                               PROSPECTUS SUMMARY
 
This summary contains basic information about us and this offering. Because it
is a summary, it does not contain all of the information that you should
consider before investing. You should read this entire prospectus carefully,
including the section entitled "Risk Factors" and the financial statements and
the related notes to those statements included in this prospectus. The term
"you" refers to prospective investors in our common stock. This prospectus
assumes that the underwriters have not exercised the over-allotment option and
gives effect to our reincorporation in Delaware and the associated exchange of
one share of common stock of CRL for every three shares of common stock of CRL's
California predecessor. The reincorporation will occur before the closing of
this offering. Unless the context otherwise requires, "CRL," "we," "us" or "our"
refer to CRL Network Services, Inc., a Delaware corporation, our predecessor,
CRL Network Services, Inc., a California corporation, and our subsidiary,
Integral Networking Corporation.
 
                           CRL NETWORK SERVICES, INC.
 
CRL Network Services is a Tier 1 Internet service provider focused on offering
tailored Internet and network management solutions to small and medium-sized
businesses. We provide an extensive array of high performance, reliable and
scalable Internet and network connectivity and value-added services designed to
meet our customers' needs. Our services include:
 
  - connectivity to the Internet and secure private networks
 
  - value-added network services such as remote management and systems
    integration
 
  - hosting services
 
We believe we were among the first companies involved in the development of
connectivity solutions and services for the commercial Internet. We have
developed our own high speed network, which enables us to reliably and
cost-effectively deliver customized, end-to-end solutions. Our competitive
strengths include our:
 
  - engineering and technical expertise arising from our direct participation in
    the evolution of the commercial Internet, which has enabled us to develop
    and construct our own sophisticated network infrastructure
 
  - high speed, facilities-based, private Layer 2 switched network, which
    enables us to maximize our quality of service by reducing latency and data
    loss as well as increasing the level of security
 
  - status as one of the first commercial Internet providers, which allows us to
    peer directly with other major Tier 1 providers reducing the costs of
    operating our network
 
  - our proprietary remote management process, acquired through our recent
    merger with Integral Networking Corporation in December 1998, which enables
    us to connect our network directly to our customer's network and provide
    remote management of our customer's network from the server to the desktop
 
As of March 15, 1999, we had 30 points of presence in major metropolitan areas
that connect to all of the interexchange points sanctioned by the National
Science Foundation for the transfer of Internet Protocol-based traffic between
Internet backbone networks. Our network is comprised of several elements,
including 23 Cascade switches, 54 Cisco routers, facilities and clear channel
fiber-optic bandwidth, which together provide a fast, secure, high quality and
fault tolerant network. Our customers include Internet service and content
providers like Internet America, Inc. and Walnut Creek CDROM, Incorporated;
companies engaged in electronic commerce like Office Depot, Inc. and Joe Boxer
Corporation; government agencies like the U.S. Federal Reserve Board and the
U.S. Department of Commerce; and educational institutions like the University of
California, Hastings College of the Law and the Woodland Hills School District.

Our objective is to become the leading nationwide provider of tailored,
end-to-end Internet and network services to small and medium-sized businesses.
To achieve this objective, we intend to:
 
  - LEVERAGE OUR EXISTING NETWORK INFRASTRUCTURE. We intend to leverage our
    status as a Tier 1 Internet service provider and competitive local exchange
    carrier in California as well as our fast, secure, reliable and scalable
    network to cost-effectively expand our customer base and deliver additional
    services to our customers.
 
  - CROSS SELL VALUE-ADDED SERVICES. We intend to leverage our existing customer
    base and future customers by aggressively cross selling our current and
    future value-added services to address their Internet and other network
    management requirements.
 
  - PROVIDE BUNDLED, END-TO-END NETWORKING SOLUTIONS. By combining our network
    infrastructure with our existing and planned array of networking services,
    we believe we are well positioned to become one of the premier, end-to-end
    providers of bundled networking solutions.
 
  - EXPAND CUSTOMER BASE AND SALES EFFORTS. We believe we will be able to
    successfully market and sell our comprehensive networking solutions to a
    large national customer base by significantly increasing our direct sales
    force and expanding our relationships with potential channel partners.
 
  - DRIVE REVENUE GROWTH BY INCREASING HOSTING SERVICES. We intend to leverage
    our physical presence and facilities located at key Internet network access
    points, which provide an attractive opportunity for us to market and sell
    hosting services to existing and potential customers.
 
  - ACCELERATE GROWTH THROUGH TARGETED ACQUISITIONS. We intend to seek
    acquisition candidates that we believe we can integrate with our existing
    network to increase our customer base or provide additional value-added
    services. In this regard, we recently acquired Integral Networking
    Corporation, which enables us to provide our remote management services.
                            ------------------------

                                  RISK FACTORS
 
You should carefully consider the risks described below before making an
investment decision. The risks and uncertainties described below are not the
only ones facing us. Additional risks and uncertainties not presently known to
us or that we currently deem immaterial may also impair our business operations.
If any of the following risks actually occur, our business, financial condition
or results of operations could be materially adversely affected. If that
happens, the trading price of our common stock could decline, and you may lose
all or part of your investment. These risk factors are not intended to represent
a complete list of the general or specific risk factors that may affect us.
 
This prospectus contains forward-looking statements. When used in this
prospectus, the words "anticipate," "believe," "estimate," "will," "may,"
"should," "plan," "future," "intend," "expect" and similar expressions identify
some of these forward-looking statements. These statements may discuss future
expectations or contain projections of results of operations or financial
condition or expected benefits to us resulting from possible acquisitions,
transactions or developments. Although we believe that our plans, intentions and
expectations reflected in these forward-looking statements are reasonable, we
can give no assurance that such plans, intentions or expectations will be
achieved. Actual results, performance or achievements could differ materially
from those contemplated, expressed or implied by the forward-looking statements
contained in this prospectus. Important factors that could cause actual results
to differ materially from our forward-looking statements are contained in this
prospectus, including under the heading "Risk Factors."
 
THE SUCCESS OF OUR GROWTH STRATEGY DEPENDS ON OUR ABILITY TO MARKET AND SELL OUR
EXISTING AND FUTURE SERVICES.
 
Historically, our business has focused on selling Internet and other network
connectivity. A critical component to the successful implementation of our
growth strategy is our ability to offer and expand the range of our value-added
services and the acceptance of those services by our existing and potential
customers. In December 1998 we merged with Integral Networking Corporation, a
systems integrator and a developer of advanced remote management services.
Before this merger, we had very little experience in either the remote
management or systems integration markets and to date have derived insignificant
revenues from services in these markets. Our future growth depends, in part, on
the acceptance and use of our remote management and systems integration services
by small and medium-sized businesses. In particular, the market for remote
management services is new, making it difficult to determine the size and growth
of the market and to predict how this market will develop. Changes in
technology, the availability of qualified information technology professionals
and other factors that make internal network management more cost-effective than
remote network management would negatively impact the market for our services.
Our business may be seriously damaged if this market fails to grow, grows more
slowly than we expect or develops in some way that is different from our
expectations. We are also actively seeking to develop or acquire a variety of
other services we can offer and cross sell. For many reasons, including the
reasons described in the risk factors below, we cannot assure you that we will
be successful in developing or acquiring those or any other services or, that if
we do, we will be successful in marketing and selling those services to our
existing or potential customers.
 
                                        5

OUR OPERATING RESULTS IN ONE OR MORE FUTURE PERIODS ARE LIKELY TO FLUCTUATE
SIGNIFICANTLY AND MAY FAIL TO MEET OR EXCEED THE EXPECTATIONS OF SECURITIES
ANALYSTS OR INVESTORS.
 
We expect to experience significant fluctuations in our future quarterly and
annual results of operations due to a variety of factors, some of which are
outside our control, including:
 
  - demand for and market acceptance of our services
 
  - capacity utilization of our facilities
 
  - fluctuations in data communications and telecommunications costs
 
  - reliable continuity of service and network availability
 
  - customer retention
 
  - the timing and success of sales and marketing efforts
 
  - the timely expansion of existing facilities and completion of new facilities
 
  - the ability to increase bandwidth as necessary
 
  - fluctuations in bandwidth used by customers
 
  - the timing and magnitude of expenditures for sales and marketing and capital
    expenditures
 
  - introductions of new services or enhancements by us and our competitors
 
  - the timing of customer installations and related payments
 
  - the ability to maintain or increase peering relationships
 
  - increased competition including the introduction by third parties of new
    Internet and network services
 
  - general growth of Internet use and establishment of Internet operations by
    enterprises
 
  - changes in our pricing policies and those of our competitors
 
  - changes in regulatory laws and policies
 
  - the success of our acquisition strategy
 
  - the timing and amount of charges related to acquisitions
 
  - economic conditions specific to the Internet and networking industry
 
In addition, a relatively large portion of our expenses are fixed in the short
term, particularly telecommunications costs, depreciation, real estate and
personnel. Consequently, our future results of operations will be particularly
sensitive to fluctuations in revenues. Over the next five years, we will record
an expense related to some of our option grants. For more information about
these charges, see "Management's Discussion and Analysis of Financial Conditions
and Results of Operations."
 
We may also encounter significant difficulties in collecting accounts receivable
in the future, particularly because many of our customers are in an emerging
stage. We cannot assure you that we will be able to collect our receivables on a
timely basis or at all.
 
Due to all of the factors listed above and the other risk factors described in
this section of the prospectus, we believe that comparisons of our results of
operations are not necessarily meaningful and should not be relied upon as
indications of future performance. As a result, our results of operations in
future periods may fall below the expectations of securities analysts and
investors. The trading price of our common stock will likely suffer a
significant decrease if that happens. For more information about our
period-to-period results, see "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

<PAGE>   11
 
THE GROWTH OF OUR BUSINESS DEPENDS ON OUR ACQUISITION STRATEGY.
 
As part of our growth strategy, we will seek strategic acquisitions of
additional assets, technologies and businesses complementary to our operations.
We may not be able to locate suitable acquisition targets or be able to acquire
any target companies we locate on acceptable terms. Our recent merger with
Integral Networking Corporation is, and any future acquisitions would be,
accompanied by the risks commonly encountered with these kind of transactions.
These risks include, among other things:
 
  - loss of customers and key personnel of an acquired company
 
  - inability to achieve cost savings
 
  - acquisition expenses and charges incurred
 
  - difficulties integrating the operations and personnel of acquired companies
 
  - additional financial resources that may be needed to fund the combined
    company operations
 
  - the potential disruption of our business
 
  - our management's ability to realize financial and strategic benefits of
    incorporating acquired technologies or businesses into our service offerings
 
  - difficulty of maintaining uniform quality control and other standards,
    policies and procedures in a larger organization
 
  - impairment of employee relationships due to changes in management or
    perceived conflicts
 
  - assumption of unexpected liabilities and incurrence of significant
    unexpected expenses in completing acquisitions
 
Any of the above risks could prevent us from realizing significant benefits from
our acquisitions. In addition, issuing our common stock in acquisitions will
dilute our stockholders' percentage interests in our company, while using cash
will deplete our cash reserves. Finally, if we are unable to account for our
acquisitions under the "pooling of interests" method of accounting, we may incur
significant, one-time write-offs and amortization charges for acquisition or
debt-related expenses, goodwill and other intangible assets. These write-offs
and charges would decrease our future earnings or increase our future losses and
could hurt the trading price of our common stock.
 
THE MARKETS FOR OUR SERVICES ARE CHARACTERIZED BY MANY COMPETING TECHNOLOGIES,
AND THE TECHNOLOGIES ON WHICH OUR SERVICES ARE BASED MAY NOT COMPETE
EFFECTIVELY.
 
The markets for network connectivity services such as Internet access,
value-added network services and hosting services, are extremely competitive and
fragmented. There are no substantial barriers to entry in these markets, and we
expect that competition will intensify in the future. We believe that our
ability to compete successfully depends upon a number of factors, including:
 
  - the capacity, reliability, low latency and security of our network
    infrastructure
 
  - our ability to maintain existing and develop future peering relationships
 
  - our technical expertise and the functionality, performance and quality of
    services
 
  - our ability to provide custom solutions for our customers
 
  - the experience and technical expertise of our sales force and engineers
 
  - the ease of access to our services
 
  - our remote management capabilities
 
  - the pricing policies of our competitors and suppliers
 
  - our ability to operate as a competitive local exchange carrier
                                        7
<PAGE>   12
 
  - our ability to scale our services to meet growing customer demand
 
  - the variety of services we offer
 
  - our geographical presence
 
  - the timing of introductions of new services by us and our competitors
 
  - the responsiveness and quality of our customer support
 
  - our financial resources
 
  - our ability to support industry standards
 
Many of our competitors have greater market presence, engineering and marketing
capabilities, and financial, technological and personnel resources than those
available to us. As a result, they may develop, deploy and expand their
communications and network infrastructures more quickly, adapt more swiftly to
new technologies and changes in customer requirements, take advantage of
acquisition and other opportunities more readily, and devote greater resources
to the marketing and sale of their services than we can. Additionally, various
organizations have entered into or are forming joint ventures or consortiums to
provide services competitive with ours.
 
Our competitors generally may be divided into four principal groups:
 
  - telecommunications carriers including regional Bell operating companies,
    often referred to as "RBOCs"
 
  - Internet service providers
 
  - network and system integrators
 
  - online network service providers
 
We believe the market for network management services will be highly competitive
if it grows as we expect. Competition will probably increase significantly as
new companies enter the market and current competitors expand their services and
product lines. Many potential competitors are likely to enjoy substantial
competitive advantages, including those listed above.
 
To be competitive, we must respond promptly and effectively to the challenges of
technological change, evolving standards and our competitors' innovations by
continuing to enhance our services, as well as our sales programs and channels.
Any pricing pressures, reduced margins or loss of market share resulting from
increased competition or our failure to compete effectively, could seriously
damage our business and financial results.
 
For a list of our principal competitors, see "Business -- Competition."
 
OUR BUSINESS MAY BE HARMED IF NEW COMPETITORS ENTER OUR MARKETS.
 
We believe that new competitors will enter our markets. These new competitors
could include large computer hardware, software, media and other technology and
telecommunications companies. Telecommunications companies and online services
providers currently offer or have announced plans to offer or expand their
network services, in some cases through acquisitions. These acquisitions may
permit our competitors to devote greater resources to developing and marketing
competitive products and services. In addition, the ability of some of our
competitors to bundle other services and products could place us at a
competitive disadvantage. Other companies are also exploring the possibility of
providing or are currently providing high speed data services using alternative
delivery methods. These alternate delivery methods include cable infrastructure,
direct broadcast satellites, digital subscriber loop technology and wireless
networks. Increased competition from new competitors could negatively affect our
business and financial results.
 
                                        8
<PAGE>   13
 
WE MAY HAVE TO REDUCE THE COST OF OUR SERVICES TO REMAIN COMPETITIVE.
 
Increased competition and industry consolidation could result in significant
pricing pressure. This pricing pressure could cause large reductions in the
average selling price of our services. For example, telecommunications companies
that compete with us may provide customers with reduced communications costs for
their Internet access or private network services, reducing the overall cost of
their solutions and significantly increasing pricing pressures on us. We may not
be able to offset the effects of any price reductions by increasing the number
of our customers, generating higher revenues from enhanced services, reducing
cost, or by obtaining approvals to operate as a competitive local exchange
carrier. We believe that the businesses of providing network connectivity,
value-added network services and hosting services will likely see increased
consolidation in the future. Consolidation could decrease selling prices and
increase competition in these industries which could erode our market share and
could have a material negative effect on our business and financial results.
 
WE DEPEND ON OUR NETWORK INFRASTRUCTURE AND OTHER SUPPLIERS TO PROVIDE
AFFORDABLE, RELIABLE, SCALABLE AND SECURE SERVICES.
 
Our success will depend upon our network infrastructure's capacity, scalability,
reliability and security, including the capacity leased from telecommunications
network suppliers. In particular, we rely on Metropolitan Fiber Systems, IXC
Communications, Inc., Qwest Communications Corporation, Cable & Wireless USA,
Inc. and other telecommunications providers for backbone and local loop
capacity. These companies provide our dedicated clear channel network, the
backbone connecting our wide area data switches. These companies also permit our
networks to interexchange Internet traffic with other Internet service providers
and distribute our services to our customers. We depend on the ability of those
companies to maintain the operational integrity of our backbone and
interconnections. If one or more of these companies is unable or unwilling to
provide or expand its current levels of service to us in the future, our
operations could be seriously and adversely affected. In addition, rapid changes
within the telecommunications industry have led to the merging of many
telecommunications companies. These mergers may cause the pricing we receive for
the services we use and the quality of service that we receive to vary
significantly, and could cause the length of time it takes to deliver the
telecommunications services that we use to increase significantly.
 
We are currently in a dispute with Qwest Communications Corporation involving
certain fiber cable they own connecting several cities. Qwest agreed to lease
fiber to us to be installed and available to us by certain specified dates.
Qwest did not complete installation as agreed. Despite their failure to install
the fiber in a timely manner, Qwest alleges that we owe them approximately
$479,000 through March 31, 1999 for use of the fiber cable. We believe Qwest is
obligated to provide us with free service as a result of this installation
delay. We are currently attempting to resolve this dispute by negotiation or
arbitration. We cannot assure you that the dispute will be resolved to our
satisfaction or that Qwest will not suspend service, potentially resulting in an
interruption of service.
 
WE DEPEND ON OUR RELATIONSHIPS WITH TELECOMMUNICATIONS CARRIERS TO PROVIDE OUR
DATA COMMUNICATIONS CAPACITY.
 
We rely on local telephone companies and other companies to provide data
communications capacity via local telecommunications lines and leased long
distance lines. These arrangements are generally terminable at will or are for a
short term. We are also subject to potential disruptions or capacity constraints
in these telecommunications services and may have no means of replacing these
services on a timely basis or at all if disruption or capacity constraints
occur. In addition, local phone service is sometimes available only from one
local telephone company in a particular market we serve. We believe that the
federal Telecommunications Act of 1996 generally will lead to increased
competition in the provision of local telephone service, but we cannot predict
the timing or extent of any such developments or the effect of increased
competition on pricing or supply. Some of our suppliers, including the regional
Bell operating companies and competitive local exchange carriers, are subject to
various price constraints, including tariff controls, which in the future may
change. Recent regulatory changes and industry consolidation may
                                        9
<PAGE>   14
 
increase the prices that these carriers may charge us. Those increases may have
a serious and negative effect on our business and financial results.
 
WE DEPEND ON OUR PEERING RELATIONSHIPS AND TIER 1 STATUS TO DELIVER OUR SERVICES
ECONOMICALLY.
 
The Internet consists of many network providers operating their own networks and
interconnecting them at various public and private peering points, through
peering arrangements with one another. Our establishment through our Tier 1
status and ongoing maintenance of peering relationships allows us to maintain
high network performance levels without paying higher non-peered transit costs
to exchange traffic with other Internet service providers. These arrangements
are not regulated, are rarely subject to any written agreement, and are subject
to revision in terms, conditions or costs over time. Network service providers
may unilaterally elect at any time not to maintain peering relationships with us
which could increase requirements or costs to maintain these peering
relationships. A loss of any of these relationships or increased pricing would
diminish the level of connectivity available to our customers or cause us to
incur additional operating expenses by requiring us to identify alternative
methods to transmit our customers' information and to pay for transit. No
economical alternatives may be available if that happens.
 
If corresponding increases in bandwidth are not added as traffic through these
exchange points increases, our ability to distribute content rapidly and
reliably through these networks will be negatively affected. Many operators of
the private peering interexchanges are also our competitors.
 
OUR FAILURE TO PROPERLY MANAGE OUR GROWTH AND EXPANSION MAY STRAIN OR EXCEED OUR
RESOURCES OR COULD HARM OUR BUSINESS.
 
To effectively grow our operations, we must continue to implement and improve
our operational, financial and management information systems and identify,
attract, train, integrate and retain qualified personnel. These demands will
require us to add new management personnel and develop additional expertise. In
particular, for us to successfully integrate newly acquired assets and continue
to implement a nationwide strategy and network, we must:
 
  - closely monitor service quality
 
  - increase our direct and indirect sales and marketing efforts
 
  - continue to implement and improve our operational, financial and management
    information systems and controls
 
  - hire, train and retain qualified personnel
 
  - continue to expand and upgrade our network infrastructure
 
We must continue to enhance and develop our network to maintain our competitive
position and continue to meet the increasing demands for service quality,
availability and competitive pricing. Despite the availability of additional
network capacity from third-party network providers, we intend to maintain the
flexibility to expand or open new points of presence or make other capital
investments as dictated by customer demand or strategic considerations. To open
new points of presence, we must spend significant amounts of money for new
equipment and leased telecommunications facilities. In addition, to expand our
customer base nationwide, we will likely have to spend significant amounts of
money on additional equipment to maintain the high speed and reliability of our
Internet and other network access services.
 
We intend to begin consolidation of our San Francisco administrative operations
in a new, larger facility during the second quarter of 1999 and to complete the
consolidation in the fourth quarter of 1999. We also anticipate completing the
expansion of our Sacramento operations center by the end of the fourth quarter
of 1999. We expect management of the transition of our information systems,
personnel and operational equipment to new facilities to place additional strain
on our resources. This transition may not be completed successfully or on a
timely basis and may require a significant amount of management's attention.
 
                                       10
<PAGE>   15
 
Our increasing customer base necessitates that our network infrastructure and
technical support resources grow accordingly. We may experience difficulties
meeting the demand for our access services and technical support. We cannot
assure you that our technical support or other resources will be sufficient to
facilitate our growth. We are striving to increase total network utilization and
to optimize this utilization throughout a 24 hour period. There will be
additional demands on our customer support, sales and marketing resources as we
pursue this utilization strategy. If we fail to manage our growth effectively,
our business and financial results will be seriously adversely affected.
 
OUR SUCCESS WILL DEPEND ON THE PERFORMANCE AND INTEGRATION OF OUR KEY PERSONNEL.
 
We recently hired several key employees and officers, including our Vice
President of Business Development. As a result, our management team has worked
together for only a brief time, and may have a limited understanding of our
specific business. Our ability to effectively execute our strategies will depend
in part upon our ability to integrate these and future managers into our
operations. We also plan to hire additional executive management personnel,
including a Chief Financial Officer, a Vice President of Sales, a Vice President
of Marketing, Vice President of Operations and Vice President of Engineering. If
our executives do not integrate effectively, our business could be materially
negatively affected. Our success also depends in significant part upon the
continued services of our senior management and key technical and sales
personnel, particularly our President and Chief Executive Officer, James Couch.
We do not maintain key man insurance on the life of Mr. Couch or any other
executive officers. Any of our officers or employees can terminate his or her
relationship with us at any time. Only Mr. Couch and Robert Ross, the President
of our subsidiary, Integral Networking Corporation, have employment agreements
for specified terms with us. For more information about Messrs. Ross' and
Couch's employment agreements, see "Management -- Employment Agreements."
 
OUR SUCCESS WILL DEPEND ON ATTRACTING AND RETAINING ADDITIONAL PERSONNEL.
 
Our success depends upon our ability to attract and retain additional highly
qualified management, technical, sales and marketing and customer support
personnel. Locating personnel with the combination of skills and attributes
required to carry out our strategy is often a lengthy process. Our future growth
particularly depends upon our ability to increase substantially the size of our
sales and marketing organization. The market for highly qualified sales and
marketing personnel is intensely competitive. We may not be successful in
meeting our hiring goals. The loss of key personnel, or the inability to attract
additional, qualified personnel, would have a material adverse effect on our
business and financial results.
 
OUR NETWORK SYSTEM COULD FAIL, AND WE MAY BE UNABLE TO PROVIDE OUR SERVICES.
 
Network expansion and growth in usage will place increased stress upon our
network hardware and traffic management systems. Our network has been designed
with redundant backbone circuits permitting traffic re-routing to make it fault
tolerant. However, we could experience failures relating to individual network
points of presence or even catastrophic failure of the entire network. Our
operations depend on our ability to protect our network infrastructure against
damage from power loss, telecommunications failures and similar events such as
damage from human error or sabotage, acts of nature, power failures and
telecommunications failures. A significant portion of our computer equipment,
including critical equipment dedicated to our Internet access services and our
switches and routers that serve large areas of the United States, are located at
our facilities in San Francisco, Palo Alto and Los Angeles, California, and
Vienna, Virginia. Our network operations center, which manages the entire
network, is in San Francisco, California. At each site, we maintain off-site
backups for our network configurations in case a natural disaster occurs. We do
not, however, have a comprehensive disaster recovery program in place. In the
past, unanticipated problems outside of our control have caused service
interruptions. A natural disaster, such as an earthquake, or other unanticipated
problem at the network operations center, at one of our hubs, sites where
routers, switches and other computer equipment that make up the backbone of our
network infrastructure are located, or at a number of our points of presence in
the future could cause, interruptions in our services, including a complete loss
of operations. In addition, our services could be interrupted if our
 
                                       11
<PAGE>   16
 
telecommunications providers fail to provide the data communications capacity in
the time frame we require as a result of a natural disaster or for some other
reason. Any damage or failure that causes interruptions in our operations could
have a material adverse effect on our business and financial results.
 
IF OUR NETWORK SYSTEM FAILS, WE COULD BE LIABLE TO OUR CUSTOMERS FOR DAMAGES.
 
Our customer contracts for several of our services currently provide a limited
service warranty related to the continuous availability of service on a 24
hour-a-day, seven day-a-week basis, except for certain scheduled maintenance
periods. This warranty is generally limited to a credit of free service for a
specified limited period of time for disruptions in Internet transmission
services. To date, only a limited number of customers has received warranty
credits for free service. Should we incur significant warranty obligations in
connection with system downtime, we cannot assure you that our liability
insurance would cover these expenses. Our customer contracts provide for our
liability for personal injury or equipment damage in only limited circumstances.
Although these customer contracts typically provide for no recovery with respect
to incidental, punitive, indirect and consequential damages resulting from
damages to equipment or disruption of service, we cannot assure you that we
would not be found liable if these damages occurred or that these damages would
be covered by or would not exceed our liability insurance.
 
OUR SUCCESS DEPENDS ON THE CONTINUED GROWTH OF THE INTERNET.
 
Many of our existing and proposed services are targeted toward Internet users.
Increased Internet use for retrieving, sharing and transferring information
among businesses, consumers, suppliers and partners has only recently begun to
develop. Our success will depend in large part on continued growth in Internet
use, which in turn will depend on a variety of factors including security,
reliability, cost, ease of access, quality of service and necessary increases in
bandwidth availability. As is typical in the case of a new and rapidly evolving
industry characterized by rapidly changing technology, evolving industry
standards and frequent new product and service introductions, demand and market
acceptance for recently introduced products and services is highly uncertain. In
addition, critical issues concerning the commercial use of the Internet remain
unresolved and may impact the growth of Internet use, especially in the business
market we target. Despite growing interest in commercial Internet uses, many
businesses have not purchased Internet access and other related services for a
number of reasons, including:
 
  - inconsistent quality of service
 
  - lack of availability of cost-effective, high speed options
 
  - a limited number of points of presence for corporate users
 
  - inability to integrate business applications on the Internet
 
  - the need to use multiple and frequently incompatible vendors
 
  - inadequate protection of the confidentiality of stored data and information
    moving across the Internet
 
  - a lack of tools to simplify Internet access and use
 
  - increased risk that third parties may obtain unauthorized access to
    confidential information
 
  - concerns arising from the year 2000 problem
 
Individuals and enterprises historically relying upon alternative means of
commerce and communication must understand and accept a new way of conducting
business and exchanging information to adopt the Internet for their means of
commerce and communication. Enterprises with substantial resources invested in
other means of commerce and exchanging information may be particularly reluctant
or slow to adopt a new strategy that may make their existing personnel and
infrastructure obsolete.
 
                                       12
<PAGE>   17
 
OUR SUCCESS DEPENDS ON THE CONTINUED ACCEPTANCE OF THE INTERNET AS A VIABLE
COMMERCIAL MEDIUM.
 
Demand for and market acceptance of the Internet are subject to a high level of
uncertainty and depend on a number of factors, including growth in consumer
access to and acceptance of new interactive technologies, the development of
technologies facilitating interactive communication between organizations and
targeted audiences, and increases in user bandwidth. If the Internet as a
commercial or business medium fails to develop or develops more slowly than
expected, our business would be materially adversely affected. The recent growth
in Internet use has caused frequent periods of performance degradation,
requiring the upgrade of routers and switches, telecommunications links and
other components forming the Internet's infrastructure by Internet service
providers, operators of interexchange points and other organizations with links
to the Internet. Any perceived degradation in the Internet's performance could
undermine the benefits of our services. Potentially increased performance
provided by our services and others is ultimately limited by and reliant upon
the speed and reliability of the networks operated by third parties.
Consequently, the emergence and growth of the market for our services depends on
improvements being made to the entire Internet infrastructure to alleviate
overloading and congestion.
 
WE MUST KEEP UP WITH RAPID TECHNOLOGICAL CHANGE AND EVOLVING INDUSTRY STANDARDS
TO COMPETE EFFECTIVELY IN OUR MARKETS.
 
The markets for our services are characterized by rapidly changing technology,
evolving industry standards, changes in customer needs, rapidly growing
competition and frequent new product and service introductions. Our future
success will depend, in part, on our ability to:
 
  - effectively use and offer leading technologies
 
  - continue to develop our technical expertise
 
  - enhance our current networking services
 
  - develop new products and services that meet changing customer needs
 
  - advertise and market our services
 
  - influence and respond to emerging industry standards and other technological
    changes
 
We must accomplish these tasks in a timely and cost-effective manner. New
technologies or industry standards may replace or provide lower cost
alternatives to our existing products and services or could render our existing
products and services obsolete and unmarketable. We also believe that our
ability to compete successfully depends on the continued compatibility and
interoperability of our services with products and architectures offered by
other vendors. Although we intend to support emerging standards in the market
for Internet and other network connectivity, new industry standards could
emerge, and we may not be able to conform to these new standards in a timely
fashion and maintain a competitive position in the market. Our pursuit of
necessary technological advances and maintenance of technological compatibility
may require substantial time and expense.
 
We face the risk of fundamental changes in the way Internet access is delivered.
Internet services are currently accessed primarily by computers connected by
telephone lines. Several companies have announced the development and sales of
cable television modems, wireless modems and satellite modems to provide
Internet access. Cable television, satellite and wireless modems can transmit
data at much faster speeds than the modems we and our customers currently use.
In addition, wireless modems may reduce the cost of network services. As the
Internet becomes more accessible through these cable television, wireless and
satellite modems and by screen based telephones, televisions or other consumer
electronic devices, or customer requirements change the way Internet access is
provided, we will have to develop new technology or modify our existing
technology to accommodate these new developments. We may also have to modify how
we deliver our services. Our pursuit of these technological advances may require
substantial time and expense, and we may not succeed in adapting our Internet
access business to alternate access devices and conduits.

OUR SUCCESS DEPENDS ON OUR ABILITY TO RETAIN EXISTING AND ATTRACT NEW CUSTOMERS.
 
Our success depends on the continued growth of our customer base and the
retention of our customers. Our ability to attract new customers will depend on
a variety of factors, including:
 
  - the willingness of businesses to outsource their mission-critical Internet
    and network operations
 
  - the capacity, reliability and cost-effectiveness of our services
 
  - our ability to effectively market and sell our services
 
Substantially all of our dedicated access customer contracts have terms of one
to three years. We have lost customers to other service providers for various
reasons, including lower pricing, incentives offered and more effective
marketing. We cannot assure you that our customers will maintain or renew their
commitments to use our services.
 
WE MAY HAVE PROBLEMS MAINTAINING HIGH QUALITY STANDARDS.
 
Market acceptance of new or enhanced services could be significantly delayed or
hindered if we introduce services with reliability or compatibility problems.
Our services may contain undetected errors or defects when first introduced.
Despite testing by us or our customers, errors may be found in new services or
enhancements after commencement of commercial deployment. Any problems or delays
could adversely affect our ability to attract or retain customers.
 
In the past we have experienced shortages in bandwidth capacity, both at the
level of particular points of presence affecting only those customers using that
particular point of presence and with system-wide services such as e-mail and
news group services. If we do not maintain sufficient bandwidth capacity in our
network connections, or insufficient bandwidth is maintained on the networks
operated by our peering partners, our customers will experience a general
slowdown of all Internet services. To protect the service levels for our
customers, we may sometimes temporarily delay adding new customers in cities or
regions experiencing significant capacity constraints until we alleviate these
capacity constraints. While our objective is to maintain excess capacity, our
failure to expand or enhance our network infrastructure on a timely basis or to
adapt it to an expanding customer base, changing customer requirements or
evolving industry standards could seriously adversely affect us.
 
If we do not achieve balanced network utilization over a 24 hour period, our
network could become overburdened at certain periods during the day, which could
diminish our quality of service by increased latency or causing our system to
fail. Conversely, due to the high fixed cost nature of our infrastructure,
under-utilization of our network during certain periods of the day could hinder
our ability to provide cost-efficient services at other times. Any failure to
achieve balanced network utilization could harm our business, financial
condition and results of operations.
 
WE MAY FACE POTENTIAL LIABILITY FOR INFORMATION DISSEMINATED THROUGH OUR
NETWORK.
 
The law relating to liability of Internet service providers for information
carried on or disseminated through their networks is not settled. A number of
lawsuits have sought to impose liability for defamatory speech, indecent
materials and infringement of copyrighted materials. The United States Supreme
Court has let stand a lower court ruling that an Internet service provider was
protected from liability for material posted on its system by a provision of the
Communications Decency Act. However, the findings in that case may not apply in
other circumstances. Other courts have held that online service providers and
Internet service providers may, under certain circumstances, be subject to
damages for copying or distributing copyrighted materials. Certain provisions of
the Communications Decency Act that imposed criminal penalties for using an
interactive computer service for transmitting obscene or indecent communications
have been found unconstitutional by the United States Supreme Court. However, on
October 21, 1998, new federal legislation was enacted that requires limits on
access to pornography and other material deemed "harmful to minors." This
legislation has been challenged in court as a violation of the First Amendment
of the United States Constitution. We are unable to predict the outcome of this
case. Potential liability imposed
 
                                       14
<PAGE>   19
 
on Internet service providers like us for material carried on or disseminated
through network systems could require us to implement measures to reduce our
exposure to that liability. These measures may require us to spend substantial
resources or discontinue certain service offerings. Our errors and omissions
insurance coverage may not be adequate or available to compensate us for all
liability that may be imposed. The imposition of liability in excess of, or the
unavailability in the future of, such coverage could have a material adverse
effect on our business or financial results.
 
WE MAY BECOME SUBJECT TO BURDENSOME AND EXPENSIVE GOVERNMENT REGULATION THAT MAY
HARM OUR BUSINESS.
 
Consistent with our growth and acquisition strategy, we are now engaged in, or
will soon be engaged in, activities that subject us to varying degrees of
federal, state and local regulation. Currently only a small body of laws and
regulations directly apply to access to or commerce on the Internet. However,
due to the Internet's increasing popularity and use, laws and regulations may be
adopted at the international, federal, state and local levels with respect to
the Internet, covering a range of issues. Moreover, a number of laws and
regulations have been proposed and are currently being considered by federal,
state and foreign legislatures with respect to such issues. The nature of any
new laws and regulations and the manner in which existing and new laws and
regulations may be interpreted and enforced cannot be fully determined. The
adoption of any future laws might decrease the Internet's growth, decrease
demand for our services, impose taxes or other costly technical requirements or
otherwise increase the cost of doing business or in some other manner have a
material adverse effect on us. In addition, applicability to the Internet of
existing laws governing issues such as property ownership, copyrights and other
intellectual property issues, taxation, libel, obscenity and personal privacy is
uncertain. As our services are available over the Internet in multiple states,
and as we facilitate sales by our customers to end users located in such states,
such jurisdictions may claim that we are required to qualify to do business as a
foreign corporation in each such state. Any such new legislation or regulation,
or the application of laws or regulations from jurisdictions whose laws may not
currently apply to our business, could have a material adverse effect on us.
 
Both the provisioning of Internet access service and the provisioning of
underlying telecommunications services are affected by federal, state and local
regulation. In March 1998, the California Public Utilities Commission approved
our ability to operate as a competitive local exchange carrier in that state.
Subsequently, we negotiated an Interconnection Agreement with Pacific Bell, the
incumbent local exchange carrier in California, which was approved by the
California Public Utilities Commission in December 1998. The agreement provides
for reciprocal compensation payments for the termination of local traffic by
either party onto the other's network. While we believe that Pacific Bell will
send more traffic to our network than we will send to theirs, we cannot assure
you that this will continue, or that Pacific Bell will pay the amounts we
believe are required under the agreement. In the past, Pacific Bell has taken
the position that Internet traffic is considered inherently long distance and
not subject to reciprocal compensation. We do not believe any amounts that we
might receive as reciprocal compensation are material to our business, but we do
intend to defend our position regarding our rights to receive fair compensation
under the agreement. On February 25, 1999, the Federal Communications Commission
ruled that calls to Internet service providers for Internet access were long
distance, not local, calls. However, the ruling upheld existing reciprocal
compensation agreements in some states, including California. If incumbent local
exchange carriers charge fees for carrying Internet traffic and Internet access
becomes more expensive, this ruling may have an adverse effect on our potential
future revenues as well as increase our costs.
 
We intend to apply for competitive local exchange carrier status in other
states. As we become a competitive local exchange carrier in additional states,
we will become subject to state requirements applicable to such carriers.

We cannot predict what regulations may be adopted in the future, or to what
extent existing laws and regulations may be found applicable, or the impact such
new or existing laws may have on our business. New laws or regulations relating
to Internet or network services, or existing laws found to apply to them, could
have a material adverse effect on our business or financial results. For a
detailed discussion of government regulation impacting our business, see
"Business -- Government Regulation."
 
WE FACE RISKS ASSOCIATED WITH BECOMING YEAR 2000 COMPLIANT.
 
The Year 2000 issue is the result of computer programs being written using two
digits rather than four to define the applicable year. As a result, date
sensitive software may recognize a date using "00" as the year 1900 rather than
the year 2000. In addition, the year 2000 is a leap year, and some computer
programs may not properly provide for February 29, 2000. System failures and
miscalculations causing disruptions of normal business activities may occur. We
are currently in the process of reviewing our services, as well as our internal
management information systems, in order to identify and modify those services
and systems that are not year 2000 compliant. We do not have and are not
developing a contingency plan in the event our systems fail due to year 2000
related problems. For a detailed discussion of our Year 2000 readiness review,
see "Management's Discussion and Analysis of Results of Operations and Financial
Condition -- Year 2000 Compliance Disclosure."
 
Based on our assessment to date, we believe that our internally developed
software is year 2000 compliant. However, we utilize software and hardware
developed by third parties both for our network and internal information
systems. We have reviewed the Year 2000 compliance statements issued by, and
have sought assurances from, some of our vendors that these vendors products are
or will be Year 2000 compliant. We intend to continue to seek assurance from
some of our suppliers that their products are or will be Year 2000 compliant. To
the extent that our systems are not year 2000 compliant, we are modifying such
systems to make them compliant. To date, we have not incurred material costs in
upgrading and replacing non-compliant items. Additionally, we are continuing to
assess the year 2000 compliance of our services and systems. We believe our
services and systems assessed to date do not contain material year 2000
deficiencies. We estimate that the capital and other costs associated with the
upgrade and conversion of our existing services and systems relating to the year
2000 issue will not be material. However, we may experience material
unanticipated problems and costs caused by undetected errors or defects in the
technology, including embedded technology, used in our internal information
technology and non-information technology systems.
 
Our services and systems operate in complex network environments and directly
and indirectly interact with a number of other hardware and software systems. We
face risks to the extent that suppliers of products, services and systems
purchased by us and others with whom we transact business, including those which
form significant portions of our network and may be sole or limited source
suppliers, do not have business systems or products that comply with year 2000
requirements. We have not received significant assurances from all of our
suppliers that their networks are year 2000 compliant. If these networks fail,
our business will be significantly impacted.
 
We do not currently have any information regarding the Year 2000 status of our
customers, many of whom are private companies. As is the case with similarly
situated companies, if our customers experience Year 2000 problems, which result
in business interruptions or otherwise impact their operations, we could
experience a decrease in the demand for our services, which could have a
material adverse impact on our business, results of operations and financial
condition.
 
We have not incurred any significant expenses to date associated with our Year
2000 plan and are not aware of any material costs associated with our
anticipated Year 2000 efforts. Our expectation that we will be able to upgrade
our services and systems to address the year 2000 issue and our expectation
regarding the costs associated with these upgrades are forward-looking
statements subject to a number of risks and uncertainties. Actual results may
vary materially as a result of a number of factors. We cannot assure you that we
will be able to timely and successfully modify our services and systems to
comply with year 2000 requirements. Any failure to do so could have a material
adverse effect on our business, results of
 
                                       16
<PAGE>   21
 
operations and financial condition. Furthermore, despite testing by us and our
vendors, our services and systems may contain undetected errors or defects
associated with Year 2000 date functions. In the event any material errors or
defects are not detected and fixed or third parties cannot timely provide us
with products, services or systems that meet the Year 2000 requirements, on our
business, results of operations and financial condition could be materially
adversely affected. Known or unknown errors or defects that affect the operation
of our services or systems could result in delay or loss of revenues,
interruption of network services, cancellation of customer contracts, diversion
of development resources, damage to our reputation, damages paid to customers
and litigation costs.
 
WE ARE SUBJECT TO THE RISKS FROM OUR LENGTHY SALES CYCLE.
 
Our customers and potential customers often take a long time to evaluate our
services. We spend a lot of time educating and providing information to our
prospective customers regarding the benefits of the Internet and our services.
Changes in the growth rate in our customer base, customer renewal rates and the
sales cycle for our services have caused, and are expected in the future to
cause, significant fluctuations in our results of operations from period to
period. In addition, we intend to significantly increase our sales and marketing
expenditures. Due to the lengthy sales cycle for our services, these expenses
will occur prior to customer commitments for our services. As a result, the
increase in our sales and marketing efforts may not result in increased sales of
our services.
 
OUR NETWORK IS SUBJECT TO SECURITY RISKS.
 
Our business depends upon the security of our network and, in part, on the
security of the network infrastructures of our third-party providers, which we
do not control. Despite implementing network security measures, the core of our
network infrastructure and the infrastructure of our network providers is
vulnerable to computer viruses, break-ins and similar disruptive problems such
as the sending of excessive volumes of unsolicited bulk e-mail caused by our
customers or other Internet or network users. Computer viruses, break-ins or
other problems caused by third parties could lead to interruptions, delays or
cessation in service to our customers, which could cause losses to us or our
customers or deter businesses from subscribing to our services. Also,
inappropriate network use by third parties could jeopardize the security of
confidential information stored in our computer systems and our customers'
computer systems and cause commercial transactions to be delayed, not completed
or completed with compromised security. We may face liability and may lose
existing or potential customers as a result. Although we intend to continue to
implement industry-standard security measures, these measures occasionally have
been circumvented in the past, and others may be able to circumvent our security
measures or the security measures of our third-party network providers in the
future. The costs and resources required to eliminate computer viruses and
alleviate other security problems may require significant expenditures,
distractions to management, and interruptions, delays or cessation of service to
our customers, all of which could harm us. Further, until more comprehensive
security technologies are developed, the security and privacy concerns of
existing and potential customers may inhibit Internet service industry growth in
general and our customer base and revenues in particular.
 
WE MAY REQUIRE SUBSTANTIAL FUTURE CAPITAL TO IMPLEMENT OUR BUSINESS PLAN.
 
We anticipate that our available cash resources, combined with the net proceeds
from this offering, will be sufficient to meet our anticipated working capital
and capital expenditure requirements for the foreseeable future. However, these
resources may not be sufficient for unanticipated working capital and capital
expenditure requirements. We may need to raise additional funds through public
or private debt or equity financings to take advantage of unanticipated
opportunities, including more rapid expansion or acquisitions of complementary
businesses or technologies or to develop new products or services. Any
additional financing we may need may not be available on terms favorable to us,
or at all.
 
                                       17
<PAGE>   22
 
WE DEPEND ON THIRD PARTIES TO SUPPLY US WITH CERTAIN HARDWARE.
 
We depend on certain third-party equipment suppliers. We purchase the components
we use to provide our networking services from third parties, including wide
area data switches supplied by Ascend Communications, Inc. and high performance
routers from Cisco Systems, Inc. The expansion of our network infrastructure and
network services places a significant demand on our suppliers, some of which
have limited resources and production capacity. We have experienced delayed
delivery from suppliers of new communications lines, switches, routers, terminal
servers, and other equipment. If our suppliers cannot adjust to meet increasing
demand, the higher demand levels may prevent them from continuing to supply
components and products in the quantities, at the quality levels and at the
times we require, or at all. If we are unable to develop alternative sources of
supply, we could experience delays and increased costs in expanding our network
infrastructure.
 
WE DEPEND ON OUR PROPRIETARY TECHNOLOGY AND TECHNOLOGICAL EXPERTISE.
 
We believe our success depends more upon our technical expertise than our
proprietary rights. We rely upon a combination of copyright, trademark and trade
secret laws and contractual restrictions to protect our proprietary technology
and rights in our services. We have no patented technology that would preclude
or inhibit competitors from entering our market. We have entered into
confidentiality and invention assignment agreements with certain of our
employees, and nondisclosure agreements with our suppliers, distributors and
appropriate customers to control access to and disclosure of our proprietary
information. Despite these precautions, a third party could potentially copy or
otherwise obtain and use our products or technology without authorization or to
develop similar technology independently. We cannot assure you that such
measures have been, or will be, adequate to protect our proprietary technology
or deter third party development of similar technologies. We also rely on
certain technologies that we license from third parties such as network
management software. We do not license any other technology that is not
generally available. These third-party technology licenses may not always
continue to be available to us on commercially reasonable terms. The loss of
such technology could require us to obtain substitute technology of lower
quality or performance standards or at greater cost, which could affect us in a
material adverse manner. To date, we have not been notified that we infringe the
proprietary rights of third parties, but there can be no assurance that third
parties will not claim infringement by us. We expect that participants in our
markets will be increasingly subject to infringement claims as the number of
technologies and competitors in our industry grows. Any such claim, whether
meritorious or not, could be time consuming, result in costly litigation, cause
service delays or require us to enter into royalty or licensing agreements. Such
royalty or licensing agreements might not be available on terms acceptable to us
or at all. As a result, any such claim could have a material adverse effect upon
our business, results of operations and financial condition.
 
THE INTERESTS OF OUR CONTROLLING STOCKHOLDER MAY CONFLICT WITH OUR AND YOUR
INTERESTS.
 
After completion of this offering, our President and Chief Executive Officer,
James Couch, will own approximately      % of our outstanding common stock,
     % if the underwriters' over-allotment option is exercised in full, and will
continue to be the President, Chief Executive Officer and Chairman of our Board
of Directors. As a result of his stock ownership and board representation, Mr.
Couch will be in a position to affect corporate actions that could conflict with
your interests and ours. Mr. Couch will have the ability to control all matters
submitted to our stockholders for approval, including the election and removal
of directors and any merger, consolidation or sale of all or substantially all
of our assets, and to control our management and affairs. This ownership
concentration may delay, defer or prevent a change in corporate control, may
impede a merger, consolidation, takeover or other business combination involving
us, or discourage a potential acquirer from making a tender offer or otherwise
attempting to obtain control of us. These circumstances could cause the price of
our common stock to decline. See "Management" and "Principal and Selling
Stockholders."
 
                                       18
<PAGE>   23
 
WE HAVE BROAD DISCRETION IN HOW WE USE THE NET PROCEEDS FROM THIS OFFERING.
 
Our management can spend most of the proceeds from this offering in ways in
which the stockholders may not agree.
 
ANTITAKEOVER PROVISIONS COULD NEGATIVELY IMPACT OUR STOCKHOLDERS.
 
Certain provisions of our certificate of incorporation and bylaws, and certain
provisions of the Delaware General Corporation Law could make it more difficult
for a third party to acquire us, even if a change of ownership would benefit our
stockholders. For more information see "Description of Capital Stock."
 
WE MAY EXPERIENCE SUBSTANTIAL SALES OF OUR COMMON STOCK AFTER THE OFFERING.
 
Sales of a substantial number of shares of common stock after the offering could
cause the market price of our common stock to decline and could impair our
ability to raise capital through the sale of additional equity securities. Upon
completion of this offering, we will have           shares of common stock
outstanding or subject to currently exercisable options or           shares if
we issue shares upon exercise of the underwriters over-allotment option. The
          shares sold in the offering, or           shares if the underwriters
over-allotment option is fully exercised, will be freely tradable without
restriction or further registration under the federal securities laws unless
purchased by our "affiliates" as that term is defined in Rule 144 under the
Securities Act. The remaining           shares of common stock outstanding on
completion of the offering will be "restricted securities" as that term is
defined in Rule 144.
 
Our stockholders and stock option holders are limited by lock-up agreements
restricting their ability to sell their CRL common stock. These securityholders
cannot sell or otherwise dispose of any shares of our common stock for a period
of at least 180 days after the date of this prospectus without the prior written
consent of CIBC Oppenheimer. When the lock-up agreements expire, the shares and
the shares underlying the options will be eligible for sale, in some cases only
by complying with the volume, manner and sale notice requirements of Rule 144.
 
THERE HAS BEEN NO PRIOR MARKET FOR OUR COMMON STOCK.
 
Prior to this offering, you could not buy our common stock publicly. An active
trading market may not develop or be sustained after this offering. The initial
public offering price will be determined by negotiation among us and the
representatives of the underwriters and may not be indicative of the price that
will prevail in the open market. See "Underwriting" for a discussion of the
factors to be considered in determining the initial public offering price.
 
WE EXPECT THE PRICE OF OUR COMMON STOCK TO BE VOLATILE.
 
The market price of our shares of common stock is likely to be highly volatile
and could be subject to wide fluctuations in response to factors such as, among
others:
 
  - actual or anticipated variations in our results of operations
 
  - announcements of technological innovations
 
  - new services introduced by us or our competitors
 
  - changes in financial estimates by security analysts, conditions and trends
    in the Internet and computer industries
 
  - fluctuations in the valuation of companies perceived by investors to be
    comparable to us
 
  - any shortfall in reserve or net income or any increase in losses from levels
    expected by securities analysts
 
  - general market conditions
 
                                       19
<PAGE>   24
 
Furthermore, the stock markets, and in particular Nasdaq, have experienced
extreme price and volume fluctuations that have affected and continue to affect
the market prices of equity securities of many technology companies. These
fluctuations often have been unrelated or disproportionate to the operating
performance of those companies. The trading prices of many technology companies'
stocks are at or near historical highs and reflect price to earnings ratios well
above historical levels. These trading prices and price to earnings ratios may
not be sustained. These broad market factors may cause the market price of our
common stock to decline. These market fluctuations, as well as general economic,
political and market conditions such as recessions, interest rate changes or
international currency fluctuations, may negatively impact the market price of
our common stock. In the past, following periods of volatility in the market
price of a company's securities, class action litigation has often been brought
against such companies. We may in the future be the target of similar
litigation. Securities litigation could result in substantial costs and distract
management's attention and resources, which would likely have a material adverse
effect on us.
 
NEW INVESTORS WILL SUFFER IMMEDIATE SUBSTANTIAL DILUTION.
 
This offering is expected to create a public market for our common stock and
will substantially increase the market value of the initial investments of our
management and other existing stockholders, particularly James Couch, our
President and Chief Executive Officer. As of March 15, 1999, our existing
stockholders hold 18,978,833 shares of our common stock. Based on an assumed
initial public offering price of $     per share, the value of the shares held
by the existing stockholders following this offering would be approximately
$     million, representing an aggregate increase of approximately $     million
over the amount of consideration paid for those shares by the existing
stockholders. In addition, the initial public offering price is substantially
higher than the book value per share of our outstanding common stock. As a
result, investors purchasing common stock in this offering will incur immediate
and substantial dilution of $     per share in the net tangible book value of
the common stock from the initial public offering price. We also have issued
options to acquire common stock at prices significantly below the initial public
offering price. As these outstanding options are exercised, there will be
further dilution. See "Dilution."

<PAGE>   25
 
              HOW WE INTEND TO USE THE PROCEEDS FROM THE OFFERING
 
Our net proceeds from the sale of the                     shares of common stock
offered by us are estimated to be approximately $     , based on an assumed
initial public offering price per share of $     , and after deducting estimated
underwriting discounts and commissions and offering expenses payable by us. If
the underwriters exercise the over-allotment option in full, and the
over-allotment shares are sold by us instead of the selling stockholder, our net
proceeds are estimated to be $          . See "Underwriting." We will not
receive any proceeds from the sale of shares by the selling stockholder. The
principal purposes of this offering are to obtain additional capital, create a
public market for our common stock and facilitate our future access to the
public capital markets.
 
We intend to use a portion of the net proceeds to repay amounts then outstanding
under our loan agreements with our banks and our capital lease. As of December
31, 1998, approximately $1,106,000 was outstanding under these agreements.
Amounts borrowed under these agreements are secured by substantially all of our
assets and bear interest at a weighted average rate equal to 9.6% as of March
15, 1999. Various portions of these borrowed amounts must be repaid in full
between July 2000 and March 2003. We also expect to use a portion of the net
proceeds for working capital and other general corporate purposes, including
expansion of our sales and marketing activities.
 
As part of our growth strategy, we intend to aggressively seek suitable
acquisition candidates, such as regional Internet service providers, that have
an existing customer base that we can add to our customer base, and companies
that have products that will enable us to expand the range of our value-added
network and hosting services. We may use a portion of the net proceeds for those
acquisitions. We have no current plans, agreements or commitments with respect
to any acquisitions, and we are not currently engaged in any negotiations with
respect to any acquisitions.
 
Pending the uses described above, we will invest our net proceeds in high
quality, income-producing securities such as short-term investment grade or
United States Government interest-bearing securities.
 
                                DIVIDEND POLICY
 
We have not paid and do not anticipate paying any cash dividends on our common
stock in the foreseeable future. We intend to retain our earnings, if any, for
use in our growth and ongoing operations.

                                 CAPITALIZATION
 
The table below sets forth our capitalization as of December 31, 1998, (i) on an
actual basis and (ii) on an as adjusted basis and to reflect our sale of the
                    shares of common stock offered by us at an assumed initial
public offering price of $     , after deducting the estimated underwriting
discounts and commissions and offering expenses, and the anticipated application
of the net proceeds. See "How We Intend to Use the Proceeds From the Offering."
The capitalization information in the table below is qualified by the more
detailed consolidated financial statements and related notes beginning on page
F-1 of this prospectus. The table should be read in conjunction with those
consolidated financial statements and related notes and the sections of this
prospectus titled "Selected Financial Data" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
The number of shares of common stock in the table below for the purposes of
determining stockholders' equity excludes 1,006,320 shares issuable upon
exercise of currently outstanding options and 1,000,000 shares available for the
grant of additional options under our 1999 Stock Incentive Plan. See
"Management -- Stock Options."

                                    DILUTION
 
At December 31, 1998, our net tangible book value was approximately $  million,
or $     per share of common stock. Net tangible book value per share represents
the amount of our total tangible assets less total liabilities, divided by the
number of shares of common stock outstanding. Net tangible book value dilution
represents the difference between the amount per share of common stock paid by
new purchasers in this offering and the net tangible book value per share after
this offering. Without taking into account any changes in net tangible book
value after December 31, 1998, other than to give effect to the sale of the
               shares of common stock offered by us, assuming an initial public
offering price of $     per share and after deducting the estimated underwriting
discounts and commissions and estimated offering expenses, our adjusted net
tangible book value at December 31, 1998 would have been approximately $
million, or $     per share of common stock. This amount represents an immediate
increase in net tangible book value of $     per share to the existing
stockholders and an immediate net tangible book value dilution of $     per
share to purchasers of common stock in the offering. The following table
illustrates this per share dilution.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 RESULTS OF OPERATIONS AND FINANCIAL CONDITION
 
The following discussion should be read with the consolidated financial
statements and related notes beginning on page F-1 of this prospectus. The
results shown in this prospectus do not necessarily suggest or predict the
results to be expected in any future periods. This discussion contains
forward-looking statements based on current expectations which involve risks and
uncertainties. Actual results and the timing of certain events may differ
significantly from those projected in these forward-looking statements due to a
number of factors, including those contained in the section entitled "Risk
Factors" and elsewhere in this prospectus.
 
OVERVIEW
 
We are a Tier 1 Internet service provider focused on offering tailored Internet
and network management solutions to small and medium-sized businesses. We
provide an extensive array of high performance, reliable and scalable Internet
and private network connectivity, value-added network and hosting services
designed to meet our customers' needs. Our operations are based in San
Francisco, California. As a Tier 1 Internet service provider, we have peering
relationships at all major domestic network access points and private peering
relationships with other major Internet service providers. We are also a
national backbone provider with a facilities-based, switched network with points
of presence in 30 major metropolitan areas. As a result of our Tier 1 status and
network, we are able to provide high speed and reliable access to the Internet,
secure private networks and hosting services. Also, our network serves as the
platform by which we are able to deliver value-added services, such as remote
management services, to our customer base. Historically, we have provided our
services to a variety of customers including consumers, other Internet service
providers, government agencies, educational institutions and businesses of
various sizes. We intend to expand our direct and indirect sales force to
increase our customer base. We also intend to cross sell our value-added service
offerings to both existing and future customers in order to provide end-to-end
service offerings. We view being an end-to-end service provider as a key element
to our strategy to increase revenues and reduce customer churn.
 
In December 1998, we acquired Integral Networking Corporation in a merger
accounted for as a pooling of interests. Integral has a ten year operating
history in the area of systems integration. Over the past three years, Integral
has developed a proprietary process to remotely manage customer networks from
the server to the desktop. We are able to leverage our existing network to
provide cost-effective remote management services to our customers from a single
location. With our remote management service, customers are able to outsource a
portion or all of their information technology departments as well as add
functionality and applications to their networks. We intend to offer remote
management services on a nationwide basis. Prior to the merger with Integral, we
had little experience in, and derived insignificant revenues from, remote
management services and systems integration.
 
Revenues. We derive our revenues from four principal services:
 
  - Internet and secure private network connectivity
 
  - remote management and other value-added services
 
  - hosting services
 
  - systems integration and hardware sales
 
Revenues from Internet and private network connectivity are typically derived
from monthly fixed prices paid by customers based upon access speed. We offer
dedicated connectivity in a range of access speeds, including fractional T1
(from 64 kilobits per second up to 1.536 megabits per second), T1 (1.536
megabits per second), T3 (45 megabits per second) and OC3 (155 megabits per
second) as well as dial-up access and transit services. We also offer our
customers the ability to upgrade access speeds as their needs
 
                                       25
<PAGE>   30
 
increase. We currently generate Internet and private network connectivity
revenues from a wide range of customers including Internet service and content
providers, businesses, government agencies and educational institutions. We
intend to increase our sales and marketing focus, particularly on small and
medium-sized businesses.
 
Revenues from our remote management services are typically derived from monthly
fees for a fixed level of service. Pricing for our remote management services is
based on the number of users and a fixed maximum number of calls per month. Our
remote management services are focused on small and medium-sized businesses.
Historically, revenues from value-added services have represented an
insignificant portion of our total revenues. With our acquisition of Integral
Networking, we intend to increase our focus on our value-added services, as
evidenced by our recent rollout of remote management services.
 
Revenues from hosting services are typically derived from monthly rates for
colocation based on space, usage-sensitive storage and access speeds. Our
customers can select from a variety of options in terms of access speeds and
space such as rack, half-rack or shelf. Our customers can purchase additional
space and increase their access speeds as needed. We will be required to expand
our facilities if our space requirements exceed our existing capacity.
 
Revenues from systems integration services are derived from hardware sales and
consulting fees. Our systems integration services including hardware sales are
currently provided primarily in California. Prior to our merger with Integral
Networking we derived insignificant revenues from hardware sales to customers,
and no revenues from systems integration services.
 
Cost of Revenues. Cost of revenues from Internet and private network
connectivity consists primarily of backbone costs and monthly access charges by
local exchange carriers to connect our customers to our network and colocation
costs. Backbone costs include all leased fiber-optic capacity to interconnect
our points of presence and to connect to public and private peering points. We
lease our fiber-optic capacity typically under short-term leases and are billed
monthly by our bandwidth providers. Colocation costs consist of monthly fees for
leasing space in facilities in which we colocate with other telecommunications
providers.
 
Cost of revenues from remote management services consists primarily of personnel
costs to provide customer support and network monitoring services. We believe
our cost of revenues from remote management services and other value-added
services as a percentage of revenues may decline as we increasingly provide
remote management services and other value-added services to existing customers
over the existing connection we provide to the customer.
 
Cost of revenues from hosting services consists primarily of rent expenses for
colocation space.
 
Cost of revenues from systems integration services consists primarily of the
cost of hardware purchased.
 
Selling and Marketing Expense. Selling and marketing expense consists primarily
of sales commissions, travel and entertainment and sales and marketing programs.
We intend to expand our investment in our sales and marketing personnel to
achieve and properly support the intended expansion in our customer base.
 
General and Administrative Expense. General and administrative expense consists
primarily of personnel expense, occupancy, general operating costs, professional
fee expenses and bad debt. We expect general and administrative expense to
increase in dollar amount in the future, reflecting anticipated growth in our
operations and the costs associated with being a publicly held company.
 
Stock-Based Compensation Expense. In connection with the grant of stock options
to employees in 1998, we recorded an aggregate deferred compensation expense of
approximately $948,000, representing the difference between the estimated fair
market value of the common stock and the option exercise price at the date of
grant. This amount is represented as a reduction of stockholder's equity and is
amortized over the vesting period of the applicable options. These valuations
resulted in charges to operations of $156,000 in the year ended December 31,
1998, and will result in charges of the remaining $792,000 over the next 5
years.
                                       26
<PAGE>   31
 
Depreciation. Depreciation expense consists primarily of depreciation of
computer equipment, office furniture and leasehold improvements. On January 1,
1998, we changed the estimated useful lives for certain networking equipment
from three to five year lives as a result of our determination, based on
historical experience, that the vast majority of assets in this class have
service lives of approximately five years.

COMPARISON OF 1998 TO 1997
 
  Revenues
 
Our revenues increased 12.7% to $11.7 million in 1998, compared to $10.4 million
in 1997. This growth in revenues resulted from an 11% increase in sales of
dedicated Internet connectivity and hosting services, a tenfold increase in
revenues derived from private network connectivity services and a 34% increase
in sales generated by systems integration services. Offsetting these increases
were reductions in revenues of $545,000 realized from dial-up customers and
reduced fees for installation services. This decrease resulted from our
increased focus on providing dedicated Internet and higher value services to
business and government customers.
 
  Cost of Revenues
 
Our cost of revenues increased 32.9% to $6.2 million in 1998, compared with $4.6
million in 1997. Of this increase, $1.2 million was primarily due to increased
connectivity charges arising from the expansion of our network. In addition, we
had increased costs of $286,000 arising from hardwares sales with our systems
integration services.
 
  Selling and Marketing
 
Our selling and marketing expenses decreased 28.9% to $371,000 in 1998, compared
to $522,000 in 1997. This decrease is attributable primarily to reduced
commissions expense. Commissions in 1998 were based upon total contract value
equalling the term of the contract multiplied by monthly service fees. The
decrease in commissions expense in 1998 results from fewer sales of longer-term
versus shorter-term contracts than in 1997 and increased purchases by our
existing customer base of increased access speeds and additional space rather
than increases in the number of new customers. We also experienced a reduction
in sales personnel in 1998.
                                       27
<PAGE>   32
 
  General and Administrative
 
General and administrative expenses increased 37.6% to $4.1 million for 1998,
compared to $3.0 million for 1997. Approximately $675,000 of this increase
relates to salaries and benefits resulting from an increase in personnel.
Facilities and related expenses increased by $424,000 primarily as a result of
the buildout of our network infrastructure.
 
  Depreciation
 
Our depreciation expense increased 22.0% to $909,000 in 1998, compared to
$745,000 in 1997. The increase is due to additional capital expenditures
incurred during 1998 for telecommunications equipment and facilities
improvements. On January 1, 1998, we changed the estimated useful lives for
certain switches and routers from three to five year lives. This change reduced
1998 depreciation by $237,000. We made this change to more accurately reflect
our historical experience with respect to the actual useful lives of the
equipment.
 
  Stock-Based Compensation
 
Stock-based compensation of $156,000 was amortized during the year ended
December 31, 1998, and stock-based compensation of $792,000 will be amortized
over the remaining vesting periods of the related options, including $394,000 in
the year ending December 31, 1999. In addition, we issued stock options to
employees during the first quarter of 1999, which will result in additional
stock-based compensation of $98,000 being recorded in 1999, $50,000 of which
will be amortized as an expense 1999. Based on these issuances of stock options
below the fair value of our stock we will record a total stock-based
compensation charge in 1999 of approximately $444,000.
 
  Net Interest Income (Expense)
 
We incurred net interest expense of $30,000 in 1998, compared to $5,000 in
income in 1997. This change was a result of increased borrowing for network
equipment under our lines of credit.
 
COMPARISON OF 1997 TO 1996
 
  Revenues
 
Our revenues increased 63.3% to $10.4 million in 1997, compared to $6.4 million
in 1996. Approximately $4.9 million of this increase is due to growth in
revenues generated by our Internet connectivity services and installation fees.
This increase was slightly offset by a $917,000 aggregate decrease in dial-up
customer and systems integration services revenues.
 
  Cost of Revenues
 
Our cost of revenues increased 38.7% to $4.6 million in 1997, compared to $3.3
million in 1996. This increase resulted from a $1.4 million increase due to
larger connectivity charges and other costs incurred with our network expansion.
In addition, costs arising from our systems integration services were $118,000
less than the prior year.
 
  Selling and Marketing
 
Our selling and marketing expenses increased 51.3% to $522,000 in 1997, compared
to $345,000 in 1996. This increase is attributable primarily to increased
commissions and travel and entertainment expenses.
 
  General and Administrative
 
General and administrative expenses increased 62.9% to $3.0 million in 1997,
compared to $1.8 million in 1996. Salaries and general office expenses increased
by $584,000 as we hired more personnel to keep pace with the growth in demand
for our services. In addition, bad debt expenses increased by $573,000.
 
                                       28
<PAGE>   33
 
  Depreciation
 
Our depreciation expense increased 45.5% to $745,000 in 1997, compared to
$512,000 in 1996. The increase was primarily the result of additional capital
expenditures incurred for telecommunications equipment and facilities
improvements.
 
FACTORS AFFECTING OPERATING RESULTS
 
We expect to experience significant fluctuations in our future quarterly and
annual results of operations due to a variety of factors, most of which are
outside our control. For a list of certain factors affecting our operating
results, see "Risk Factors -- Our operating results in one or more future
periods are likely to fluctuate significantly and may fail to meet or exceed the
expectations of securities analysts or investors" and the other risk factors
described in this prospectus. Due to all of these factors, we believe that
period-to-period comparisons of our operating results are not necessarily
meaningful and should not be relied upon as indications of future performance.
 
YEAR 2000 COMPLIANCE DISCLOSURE
 
The Year 2000 issue is the result of computer programs being written using two
digits rather than four to define the applicable year. As a result,
date-sensitive software may recognize a date using "00" as the year 1900 rather
than the year 2000. In addition, the year 2000 is a leap year, and some computer
programs may not properly provide for February 29, 2000. System failures and
miscalculations causing disruptions of normal business activities may occur
including, among other things, a temporary inability to process transactions,
send invoices, or engage in similar normal business activities. As a result,
many companies' software and computer systems may need to be upgraded or
replaced in order to comply with Year 2000 requirements. We are currently in the
process of reviewing our services, as well as our internal management
information systems, in order to identify and modify those services and systems
that are not year 2000 compliant. We do not have and are not developing a
contingency plan in the event our systems fail due to year 2000 related
problems.
 
We have begun the first phase of our Year 2000 readiness review. The review will
include assessment, implementation, testing, and upgrading or replacing
non-compliant items as appropriate. To date, we have evaluated our internally
developed software and believe that it is Year 2000 compliant. However, we
utilize software and hardware developed by third parties both for our network
and internal information systems. We have reviewed the Year 2000 compliance
statements issued by, and have sought assurances from, some of our suppliers
that their products are or will be Year 2000 compliant. We intend to continue to
seek assurances from our other suppliers. To the extent that our systems are not
year 2000 compliant, we are modifying such systems to make them compliant. We
expect these modifications will be made on a timely basis and do not believe
that the cost of the modifications will have a material effect on our business,
results of operations or financial condition. To date, we have not incurred
material costs in upgrading and replacing non-compliant items. Additionally, we
are continuing to assess the Year 2000 compliance of our services and systems.
We believe our services and systems assessed to date do not contain material
year 2000 deficiencies. We estimate that the capital and other costs associated
with any upgrade and conversion of our existing services and systems relating to
the Year 2000 issue will not be material.
 
We expect to continue assessing and testing our internal information technology,
which we refer to as IT, and non-IT systems into 1999. We are not currently
aware of any material operations issues or costs associated with preparing our
internal IT and non-IT systems for the year 2000. However, we may experience
material unanticipated problems and costs caused by undetected errors or defects
in the technology, including embedded technology, used in our internal IT and
non-IT systems.
 
Based upon the public filings, press releases and other publicly available
information regarding our primary equipment, telecommunications and data
communications providers, we are aware that these providers are in the process
of reviewing and implementing their own Year 2000 compliance programs. We do not
believe that we will be afforded the opportunity to test the systems of these
providers. If our primary providers experience business interruptions as a
result of the failure to achieve Year 2000 compliance, our
                                       29
<PAGE>   34
 
ability to provide Internet connectivity could be impaired, which could have a
material adverse effect on our business, results of operations and financial
condition.
 
Our services and systems operate in complex network environments and directly
and indirectly interact with a number of other hardware and software systems. We
face risks to the extent that suppliers of products, services and systems
purchased by us and others with whom we transact business, including those which
form significant portions of our network and may be sole or limited source
suppliers, do not have business systems or products that comply with Year 2000
requirements. We have not received significant assurances from all our suppliers
that their networks are Year 2000 compliant. If these networks fail, our
business will be significantly impacted.
 
We do not currently have any information regarding the Year 2000 status of our
customers, many of whom are private companies. As is the case with similarly
situated companies, if our customers experience Year 2000 problems, which result
in business interruptions or otherwise impact their operations, we could
experience a decrease in the demand for our services, which could have a
material adverse impact on our business, results of operations and financial
condition.
 
We have not incurred any significant expenses to date associated with our Year
2000 plan and are not aware of any material costs associated with our
anticipated Year 2000 efforts. Our expectation that we will be able to upgrade
our services and systems to address the year 2000 issue and our expectation
regarding the costs associated with these upgrades are forward-looking
statements subject to a number of risks and uncertainties. Actual results may
vary materially as a result of a number of factors. We cannot assure you that we
will be able to timely and successfully modify our services and systems to
comply with year 2000 requirements. Any failure to do so could have a material
adverse effect on our business, results of operations and financial condition.
Furthermore, despite testing by us and our vendors, our services and systems may
contain undetected errors or defects associated with Year 2000 date functions.
In the event any material errors or defects are not detected and fixed or third
parties cannot timely provide us with products, services or systems that meet
the Year 2000 requirements, our business, results of operations and financial
condition could be materially adversely affected. Known or unknown errors or
defects that affect the operation of our services or systems could result in
delay or loss of revenues, interruption of network services, cancellation of
customer contracts, diversion of development resources, damage to our
reputation, damages paid to customers and litigation costs.
 
LIQUIDITY AND CAPITAL RESOURCES
 
We have historically generated positive cash flows from operating activities and
have financed our growth, as well as all necessary capital expenditures and
working capital needs, primarily through the use of internally generated funds
and lines of credit. In addition, we have made limited use of capital lease
financing. We expect to experience a substantial increase in our operating
expenses as we implement our growth strategy and incur expenses for hiring new
personnel and for additional leased network capacity. We also anticipate an
increase in our capital expenditures consistent with our anticipated need for
additional network infrastructure. We expect our operating expenses and capital
expenditures will be a significant use of our cash resources.
 
We currently have agreements with commercial lenders providing a revolving line
of credit and equipment financing arrangements. Integral also has a line of
credit with a commercial lender. As of December 31, 1998, approximately
$1,106,000 was outstanding under these agreements. Amounts borrowed under these
agreements are secured by substantially all of our assets and bear interest at a
weighted average rate equal to 9.6% as of March 15, 1999. Various portions of
these borrowed amounts must be repaid in full between July 2000 and March 2003.
We intend to use a portion of the proceeds from the offering to repay the
amounts outstanding under these loan agreements. See "How We Intend to Use the
Proceeds from the Offering."
 
Our net cash flows from operating activities were $705,000 for 1998, $1.7
million for 1997, and $944,000 for 1996. Our borrowings were $703,000 for 1998,
$358,000 for 1997 and zero for 1996. At December 31, 1998, we had $840,000 in
cash and cash equivalents.
                                       30
<PAGE>   35
 
Net cash used in investing activities was $1,529,000 for the year ended December
31, 1998, $1,182,000 for the year ended December 31, 1997, and $905,000 for the
year ended December 31, 1996. Cash used in investing activities was primarily
used to purchase property and network equipment.
 
Net cash provided by (used in) financing activities was $549,000 for the year
ended December 31, 1998, $316,000 for the year ended December 31, 1997 and
$(14,000) for the year ended December 31, 1996. In the years ended December 31,
1998 and 1997, net cash provided by financing activities resulted primarily from
borrowings. Net cash used in financing activities in the year ended December 31,
1996, resulted from debt payments.
 
We believe that the net proceeds of this offering, together with our existing
cash, cash equivalents and short-term investments and available credit
facilities, will be sufficient to meet our anticipated cash needs for working
capital, repayment of debt and capital expenditures for the foreseeable future.
 
RECENTLY ISSUED ACCOUNTING STANDARDS
 
In March 1998, the Accounting Standards Executive Committee of the American
Institute of Certified Public Accountants issued SOP 98-1, Accounting for the
Costs of Computer Software Developed or Obtained for Internal Use. SOP 98-1
provides guidance for an enterprise on accounting for the costs of computer
software developed or obtained for internal use. SOP 98-1 is effective for us in
fiscal 1999. We anticipate that accounting for transactions under SOP 98-1 will
not have a material impact on our financial position or results of operations.
 
In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, which defines derivatives, requires that all
derivatives be carried at fair value, and provides for hedge accounting when
certain conditions are met. SFAS No. 133 is effective for us in fiscal 2000. We
do not believe adoption of this statement will have a material impact on our
financial position or results of operations.

INDUSTRY OVERVIEW
 
To remain competitive, businesses today must have the ability to reliably access
and share information both externally and internally. In response, companies are
increasingly conducting business over the public Internet and their own private
networks. As a result, businesses are expanding their connectivity to the
Internet and use of both local area networks, commonly referred to as LANs, and
wide area networks, commonly referred to as WANs. The Internet's functionality
and accessibility have created an increasingly attractive commercial medium to
quickly and efficiently provide services and distribute information that
historically has been more difficult to obtain through traditional communication
channels. At the same time, businesses are continuing to develop private
networks to distribute and share information, resulting in a dramatic increase
in private network traffic as well as heightened performance requirements for
these networks. Increased use of the Internet and public and private networks
has also driven growth in the amount of sensitive corporate information shared
over networks, causing network security to become a high
 
                                       32
<PAGE>   37
 
priority for many businesses. As a result of these trends, a growing number of
businesses view responsive, reliable and secure networks as mission-critical to
their operations.
 
The proliferation of Internet use is driven by the emergence of electronic
commerce and availability of applications such as the outsourcing of help desk
functions, Internet Protocol-based voice, fax and video conferencing, purchasing
and provisioning functions, and corporate and product marketing. Businesses are
confronted with increasing customer demand for offerings of products and
services over the Internet as a result of the immediacy and convenience it
affords. As the Internet evolves, companies are transitioning from utilizing the
Internet for mission-supportive functions such as marketing and customer
support, to mission-critical functions such as transaction execution, including
sales orders and customer billing. Also, many businesses have emerged that focus
solely on delivering services over the Internet through Web sites and electronic
commerce applications. Their ability to offer these kinds of products and
services requires high bandwidth Internet sites and operations. Due to advances
in on-line security and payment mechanisms, the number of businesses
establishing commerce-enabled Web sites is expected to increase dramatically.
International Data Corporation estimates that the number of consumers buying
goods and services on the Internet will grow from 18 million in 1997 to 128
million in 2002, and that the total value of goods and services purchased over
the Internet will increase from approximately $12 billion in 1997 to
approximately $425 billion by 2002. Businesses are positioning themselves to
capture this rapid growth opportunity by enhancing their Internet presence.
 
The need for businesses to establish secure private wide area networks has been
driven by the growing importance of connecting the geographically dispersed
sites of their business, their customers and their suppliers. As networks become
a more integral part of day-to-day operations, many companies seek to minimize
network costs and improve operating efficiencies. Traditional wide area network
architectures consist of dedicated circuits between computing facilities
utilizing the same fixed bandwidth regardless of traffic flow. New switched data
technologies share and dynamically allocate bandwidth based on prevailing
traffic patterns. The shared bandwidth of switched data technologies typically
results in wide area networks that are more reliable and cost-efficient than
those based on traditional leased-line services.
 
Local area networks have emerged from businesses' need to access and share
internal electronic information. To enable effective internal communication and
distribution of company information, the local area network is used by
businesses seeking to decentralize their information databases. Local area
networks facilitate access to client/server-based technology such as Web-enabled
databases, shared file servers, e-mail, electronic commerce applications, and
other online information. Use of local area networks will continue to grow as
businesses increasingly decentralize information.
 
As local area networks and wide area networks become more prominent, businesses
increasingly need remote access to their network for mobile workers. Many
businesses recognize the importance of controlling the method by which
electronic automation takes place and ensuring the security of communications
between mobile workers and the proprietary networked resources they access. The
benefits of efficiently distributing proprietary information to those with a
need to know must be weighed carefully against the possibility that unauthorized
access to sensitive information can occur due to failed security mechanisms or
poor network design.
 
Internet access services provided by Internet service providers interconnect
businesses and individuals to the Internet, private data networks and other
interconnected networks. Access services include high speed dedicated access
used primarily by medium-sized and larger organizations and dial-up access for
individuals and small or home office businesses. In addition to Internet access
services, business-focused Internet service providers are increasingly providing
a range of value-added communications services, including remote management,
shared and dedicated Web hosting, server colocation, network security services,
electronic commerce applications and new applications such as Internet
Protocol-based voice, fax and video conferencing.
 
Several different types of Internet service providers have emerged and are
generally referred to as Tier 1, Tier 2, and Tier 3 network service providers.
International Data Corporation defines a Tier 1 network service provider as an
operator of a high quality, national backbone facility, specializing in leased
line
                                       33
<PAGE>   38
 
connectivity. Also according to International Data Corporation, Tier 1 network
service providers peer directly at the National Science Foundation-approved
network access points. International Data Corporation defines Tier 2 and Tier 3
network service providers as those who do not have a national backbone network.
 
Peering is critical to providing high quality, high speed Internet access. By
peering directly with other networks, Tier 1 Internet service providers are able
to send Internet traffic via the most direct and reliable path to its final
destination (the fewest "hops"), thereby minimizing potential delay and lost or
corrupted data. Additionally, Tier 1 Internet service providers usually maintain
and control their own national backbones and are better able to control the
quality of service, level of data integrity and degree of reliability than
non-Tier 1 Internet service providers. Because Tier 1 Internet service providers
typically do not pay for the privilege of interconnecting with other Tier 1
networks, they can increase their available Internet capacity by expanding
existing peering connections with their peer networks without the high costs
associated with the retail purchase of additional Internet access. As the number
of Internet service providers has grown, Tier 1 Internet service providers have
increased their requirements for peering arrangements, which has raised the
barriers to acquiring and maintaining Tier 1 status.
 
The internal network design of the Internet service provider's network is also a
significant factor in determining the speed and reliability of data delivery
from source to destination. Traditional networks constructed solely of routing
devices require that a packet of information stop at a router in every point of
presence along the traveled network path. Each of these routed hops requires the
data packet to be examined by the router and a policy-based routing decision to
be made regarding the egress of the packet back onto the network. Many routing
decisions can delay the delivery of the packet to its destination. By contrast,
switched data networks can deliver information directly between the source and
destination without the need to disassemble the data packets during transit. As
a result, switched data networks generally provide higher speeds, lower latency
and overall better quality of service than traditionally routed networks.
 
THE MARKET OPPORTUNITY
 
  Overview
 
Internet and private network operations are increasingly becoming
mission-critical to the commercial and communication operations of businesses.
The evolution and expansion of Internet services and the networks over which
they are delivered has led to a growing need for end-to-end, bundled Internet
and network services.
 
  The Need for Internet Connectivity Services
 
The Internet continues to increase in size and importance as its role in
mission-critical business operations expands. Businesses are looking to third
party providers for expertise in implementing their Internet strategies.
According to Forrester Research, Internet access revenues from businesses are
expected to increase from less than $1 billion in 1997 to more than $16 billion
in 2002. Internet service providers are ideally positioned to capitalize on this
growing need of businesses to access and utilize more of the Internet.
 
  Demand for Secure Private Networks
 
Historically, data communications services offered over private leased lines
were expensive, not monitored or managed for quality of service nor fault
tolerant. Seeking a less expensive alternative, some businesses use the public
Internet for communications but are confronted with potential problems inherent
in the structure and management of the Internet, such as unauthorized access and
data loss and reduced transmission speed, commonly referred to as degradation.
Virtual private networks are also used as another less expensive alternative,
but similarly include security concerns and unreliable performance due to their
reliance on the Internet for data transmission. By contrast, Layer 2, switched
private networks offer a
 
                                       34
<PAGE>   39
 
networking option which is more cost-effective than traditional point-to-point
private leased lines but is an owned and controlled network not depending upon
the Internet for data transfer, eliminating security concerns and permitting
lower and more stable latency levels than data communications alternatives
relying upon the Internet.
 
  Enhanced Network Management Services
 
Businesses need to ensure that their networks, information systems and
applications operate continuously as their reliance on public and private
networks increases. While large businesses are able to build and maintain
information technology departments capable of servicing their networks,
information systems and applications, small and medium-sized businesses find it
difficult to cost-effectively maintain information technology departments
capable of ensuring the continuous availability of complex networks running
multiple applications. It is also difficult and expensive for small and
medium-sized businesses to continuously train their information technology
departments to support new technologies and applications. As a result, many
small and medium-sized businesses have chosen to outsource their information
technology department functions to third parties capable of offering a full
range of these services. Traditionally, outsourcing information technology
services has required site visits from the service provider even for routine
problems often resulting in lengthy delays. As a result, small and medium-sized
businesses are seeking the ability to affordably outsource their information
technology departments to third parties capable of rapidly responding to
problems and minimizing network downtime. International Data Corporation reports
that the U.S. market for network monitoring and management was $2.4 billion in
1998 and is projected to reach $4.7 billion in 2002, representing an 18% annual
growth rate.
 
  Hosting Services
 
As Internet presence becomes increasingly critical to business operations, many
businesses are seeking to outsource hosting services, including Internet
colocation, to network service providers. By outsourcing these functions,
businesses can establish a strong Internet presence while remaining focused on
their core business operations. According to Forrester Research, revenues from
complex Web hosting will increase from approximately $200 million in 1997 to $8
billion in 2002, while intranet hosting will generate nearly $400 million in
revenues for Internet service providers by 2002. Traditional hosting companies
operate geographically dispersed networks that are subject to increased risks of
latency and data degradation or loss, as data travels across multiple network
connections, or hops. Many hosting companies also do not have the flexibility,
peering arrangements or capacity to quickly scale their services to meet the
sharp growth and high bandwidth requirements of mission-critical Internet
operations. Network service providers who are able to overcome these obstacles
will be well positioned to capitalize on the growth of the Web hosting market.
 
OUR SOLUTION
 
Through our national, facilities-based, fully-peered network, we offer our
customers high performance, flexible and scalable services, including:
 
  - connectivity to the Internet and secure private networks
 
  - value-added services such as remote network management and systems
    integration
 
  - hosting services
 
Our comprehensive suite of services enables our customers to easily and more
cost-effectively address their networking needs without having to assemble
services from different vendors including value-added resellers, Internet
service providers and information technology service providers. Our ability to
provide "one-stop," customized network solutions facilitates our customers'
ability to exploit opportunities created by the Internet and other network
systems on a timely basis. Key advantages of our solution are:
 
High-Quality Performance and Reliability. Our national, facilities-based, Layer
2, switched backbone network, coupled with our status as a Tier 1 Internet
service provider, enables us to provide our customers
                                       35
<PAGE>   40
 
with some of the fastest and most reliable data transmission solutions
available. Our network operations center controls and monitors the switches,
routers and fiber-optic capacity for all data transmitted over our network 24
hours-a-day, seven days-a-week, allowing our staff to be immediately aware and
responsive to problems as they arise. This control of our network infrastructure
allows us to improve quality of service by minimizing network down time.
 
Outsourcing of Mission-Critical and Support Operations. We offer our clients the
ability to outsource their network management operations to us. Through a remote
connection and our proprietary process, we are capable of managing our
customers' internal networks as well as solving common problems that our
customers encounter. When end-users encounter a problem, we are able to attach
in real-time to our customer's desktop computers and servers to evaluate and
solve the problem as if located on-site at the customer's premise. In addition,
we proactively monitor our customers' networks to predict and, in some cases,
prevent outages. The ability to manage our customers' systems remotely enables
us to offer tailored and cost-effective network management solutions. Businesses
able to outsource many aspects of an information technology department, from the
"help desk" to enterprise-wide server maintenance, can implement more complex
applications without being constrained by a lack of in-house computer
professionals. We believe that our services can enable our customers to
implement selected intranet and extranet business functions such as electronic
commerce, free of any information technology-related concerns. Our solutions
allow our customers to more rapidly grow their businesses with relatively modest
initial and recurring information technology-related expenditures.
 
Scalability and Flexibility. Our services are designed to be highly scalable and
flexible in order to meet the needs of our customers as their Internet, network
operations, and bandwidth requirements expand. Our network is designed to
provide our customers with available and uncongested bandwidth during network
traffic spikes by maintaining excess capacity and additional sources of
bandwidth. We also provide flexibility for our customers by supporting most
leading Internet hardware and software systems vendor platforms.
 
Bundled Service Offerings. Many enterprises today, especially those in the small
and medium-sized business market, often purchase services from a number of
vendors. For example, a company may receive its Internet access, file/Web server
connection and colocation space all from different vendors. We are able to offer
these services under customized packages through a single network connection and
also offer additional customer support and management expertise. We are able to
serve our customers' Internet and network management requirements without the
need for any additional service providers or connections.
 
STRATEGY
 
Our objective is to become the leading nationwide provider of tailored,
end-to-end Internet and network services to small and medium-sized businesses.
To achieve this objective, we intend to:
 
Leverage Our Existing Network Infrastructure. Through our direct participation
in the development and evolution of the commercial Internet, we are one of only
a small number of Tier 1 Internet service providers, which means we have legacy
peering relationships with major Internet service providers, including MCI
WorldCom, Inc., Sprint Corporation and Cable & Wireless P.L.C. As a result, we
can transfer traffic efficiently to other networks without paying the costs
typically associated with transport. During the past year, we became a licensed
competitive local exchange carrier in the State of California and have begun the
application process to become a competitive local exchange carrier in several
other states to complement our national backbone network. As a competitive local
exchange carrier in any particular state, we are able to purchase unbundled
network elements from the applicable regional Bell operating company operating
in that state rather than purchase retail local loops, resulting in a
significant cost savings to us. Also, our 15 years of experience developing our
network provides us with an in-depth understanding of the key elements of
network connectivity technology. As a result, over the past decade we have built
a national backbone network which currently consists of clear channel
fiber-optic capacity, Cascade switches and Cisco routers, which are controlled
through our network operations center. Our network is fast, secure and reliable,
as well as scalable to approximately one hundred times the traffic our
 
                                       36
<PAGE>   41
 
current customers generate. We intend to aggressively leverage our existing
network infrastructure to cost-effectively expand our customer base and deliver
additional service to our customers.
 
Cross Sell Value-Added Services. We intend to leverage our existing customer
base and future customers by aggressively cross selling our value-added
services. We are committed to offering our customers reliable value-added
network services necessary to address their Internet and network management
requirements. We believe we are currently one of only a few companies remotely
managing the customer's network from the Internet all the way to the desktop.
Based on our existing network infrastructure and expertise, we are able to offer
these services continuously, reliably and on a cost-effective basis. Through
acquisitions or development of relationships with providers of leading Internet
and other network technologies, we intend to enhance and increase the services
we offer to include other value-added services, such as enhanced network
security solutions, that address our customers' rapidly evolving
mission-critical networking needs such as electronic commerce.
 
Provide Bundled, End-to-End Networking Solutions. The fragmentation among
Internet and other network service providers has resulted in users often faced
with an overwhelming array of providers and services from which to choose. For
example, it is typical for a user to purchase local loop connectivity from a
regional Bell operating company or a competitive local exchange carrier, to
purchase Internet or other wide area network connectivity from a separate
Internet or other network service provider, and to purchase network services,
like remote management, systems integration and network security, from one or
more other companies. We believe the Internet and network service provider model
is evolving towards providers who are capable of providing end-to-end solutions
by bundling several or all of these functions efficiently, reliably and on a
cost-effective basis. By combining our network infrastructure with our existing
and planned array of value-added networking services, we believe we are well
positioned to become one of the premier, end-to-end providers of bundled
networking solutions to small and medium-sized businesses. Additionally, we
believe that by offering bundled services, we can reduce customer loss, commonly
known as "churn," increase network usage by existing customers, cross sell
additional services to existing customers and differentiate ourselves from our
competitors.
 
Expand Customer Base and Sales Efforts. We intend to expand our customer base by
significantly increasing our direct and indirect sales forces as well as our
marketing efforts. Our direct sales force consisted of 20 persons in three sales
offices as of March 15, 1999. As of that date, we had sales offices in three
major metropolitan areas. Our sales force is supported in their efforts by sales
engineers and, in many instances, our senior management. We intend to increase
the number of our sales offices and to significantly expand the size of our
direct sales force with the goal of having an effective selling presence in all
major domestic metropolitan and regional markets. In addition, we are exploring
other strategies to grow our direct sales force, including developing an inside
sales center to generate additional sales. We also intend to establish and
expand relationships with potential channel partners including hardware vendors,
value-added resellers, system integrators and Web hosting companies to leverage
their sales organizations and existing customer bases. By combining an expanding
direct sales force with the sales and marketing power of targeted channel
partners, we believe we will be able to effectively market and sell our
comprehensive networking solutions to a large potential customer base throughout
the United States.
 
Drive Revenue Growth by Increasing Hosting Services. Our physical presence at
key network access points provides attractive opportunities for many customers
to lease a portion of our space and purchase our colocation services. Our
hosting services permit our customers to install their equipment in close
physical proximity to major Internet access points. These connections at the
"edge" of the Internet are among the most reliable connections available. Our
presence in these locations, as well as the hardware we have installed there,
are designed to satisfy the electronic commerce and other requirements of the
most demanding Internet service providers, content providers, businesses and
government agencies. We intend to aggressively market our existing hosting
services to service these mission-critical applications.
 
Accelerate Growth Through Targeted Acquisitions. The goal of our acquisition
strategy is to accelerate market penetration, build upon our core competencies
and expand our technical staff and sales force. We evaluate acquisition
candidates based on their fit with our overall business plan. When a candidate
is
 
                                       37
<PAGE>   42
 
acquired, we will integrate our existing Internet and network connectivity and
value-added services with the service offerings of the acquired company and
leverage the acquired sales force and customer base to expand market
opportunities. The types of acquisitions we target include business Internet
service providers and companies with leading edge network connectivity and
services technologies that expand or enhance our existing services. Other types
of targeted acquisitions include local or regional business Internet service
providers in markets where we have established points of presence and would
benefit from the acquired company's local sales force and installed customer
base through the potential increase in our network utilization. Our recent
acquisition of Integral Networking Corporation, a systems integrator and
developer of advanced remote management services, is an example of the
implementation of this strategy.

needs.
 
  Network Connectivity Services
 
We are a national provider of connectivity services, including a variety of
dedicated and dial-up access and customized wide area networking solutions in
both stand-alone and bundled packages, which provide high-speed continuous
access to the Internet and other networks for our customers. We also provide
turnkey configuration solutions encompassing such services as domain name
registration, leased-line ordering and installation assistance, Internet
Protocol address assignment, router configuration, installation and management,
and technical consultation services. All of our connectivity customers receive
24 hour-a-day, seven day-a-week technical support.
 
Dedicated Access. We offer a broad line of high speed dedicated connectivity
services providing business customers with direct access to a full range of
Internet applications. Our dedicated access service provides companies with
robust, full-time, dedicated Internet connectivity in a range of access speeds,
including fractional T1 (from 64 kilobits per second up to 1.536 megabits per
second), T1 (1.536 megabits per second), T3 (45 megabits per second) and OC3
(155 megabits per second). Our dedicated Internet access is designed to help
ensure bandwidth availability for priority business applications. We believe
that the traffic-management advantages of the data switching technology deployed
in our network provide our customers with fully integrated Internet access and
improved performance.
 
Customized Wide Area Networking Solutions. We are dedicated to providing high
performance, privately managed wide area networking services. Our customized
wide area networking services combine the high performance of private lines with
the redundancy and bandwidth efficiency of a switched service. These wide area
networking services utilize the superior line management features and
cost-effectiveness of data switching technology to provide a high performance
and secure wide area network that is scalable to our customers' growing network
demands.
 
The versatility of data switching technology allows our customers to easily
manage connectivity to multiple sites at a wide range of connection speeds. With
our customized wide area networking services, our engineers can help a customer
design a network to match the specific needs of the customer. Locations can be
partially or fully-meshed, offering route redundancy where necessary, and
allowing the customer to provision only the bandwidth they need.
 
By linking a wide area network with our Internet backbone, our customers can
optimize the bandwidth of their businesses and minimize expenses. We also offer
service level guarantees and extensive 24 hour-a-day, seven day-a-week customer
support with all of our integrated solution products.
 
Dial-Up Access. Our dial-up services offer a cost-effective, entry-level

ordinary telephone lines at speeds of up to 56 kilobits per second using V.90
protocol.
 
                                       38
<PAGE>   43
 
Transit Service. Our transit service is designed for Internet service providers
with existing connectivity to one or more peering points. The service provides
for the announcement of our customer's networks to our other peering partners,
the announcement of our other peers' networks to our customer, and for the
transit of data between our customer and our other peers. This service can
usually be installed in a short time frame and gives our customers the
flexibility they need to expand their operations.
 
  Value-Added Services
 
We believe that businesses will continue to increase their use of the Internet
and private networks to remain competitive and will increasingly rely upon an
expanding range of value-added services to enhance productivity, reduce costs
and improve service reliability. We offer a variety of value-added services,
including remote management and systems integration. As part of our strategic
plan, we also intend to offer network security services. In addition, to
capitalize on our technologically advanced, high-capacity network
infrastructure, we intend to continue developing new value-added services that
facilitate customer use of the Internet and other networks, including
bandwidth-intensive multimedia services such as video conferencing.
 
Remote Management Services. Traditional outsourced network management solutions
require network problems to be diagnosed and resolved at the customer's site,
which often results in a lengthy response time. Through our alarm notification
capability, our monitoring service immediately alerts us to our customers'
network problems and details the reason for the problem. We are capable of
managing our customers' internal networks and solving common problems
encountered by our customers through a remote connection and proprietary process
which permits us to attach in real-time to our customers' desktop computers and
servers and evaluate and solve the problem as if located on-site at our
customers' premise. For these reasons, our remote management services help to
significantly reduce the necessary time and expense to diagnose and resolve
network and application-oriented problems. Our remote management solution is
also structured to be scalable to our customers' growing needs.
 
Systems and Network Integration. We provide integration services such as local
and wide area network configurations, Web and database server integration and
application-specific software solutions. We configure equipment by loading
customer programs, connecting equipment to the network and servicing hardware
and software. Our staff of engineers, many of whom are Novell Platinum providers
or Microsoft MCSP-certified, work closely with our customers to design,
assemble, configure and install a network architecture meeting our customers'
requirements.
 
Firewall Solutions. The sensitive nature of business Internet traffic demands
protection from unauthorized access. Our firewall solutions provide users with
secure access to the Internet as well as create an electronic barrier between a
customer's internal network and the public Internet. Our firewalls can also
restrict access between departments as well as track communications to ensure
that these communications follow a customer's established security procedures.
We work with a variety of vendors to provide customized firewall solutions for
each of our customers with specialized security needs.
 
  Hosting Services
 
Our existing network infrastructure, with a presence at all major domestic
network access points, provides an easy and cost-effective solution for
businesses to directly connect their equipment to the Internet and other
networks through our existing nationwide backbone. Our colocation facilities
allow our customers to install their equipment as close to our network core as
physically possible and are configured in a manner to satisfy their
mission-critical networking and Internet operations. Our infrastructure supports
the Internet hardware and software vendor platforms of most leading vendors,
including Intel Corporation, Microsoft Corporation and Sun Microsystems, Inc.
The flexibility and scalability of our network infrastructure permits our
customers to purchase additional space and power as needed, and to install and
maintain their own hardware and software. Our primary colocation facilities have
uninterruptible AC or DC power supply and back up equipment, fire suppression
equipment, HVAC
 
                                       39

(heating, ventilation and air conditioning), separate cooling zones,
seismically-braced racks and high levels of physical security, including card
key access and video surveillance.
 
Customers can select from a variety of options including shared rack facilities,
highly secure cabinets and enclosed cage facilities based upon their business
and technical requirements. Because many applications are dynamic and require
immediate hardware and software upgrades to maintain or achieve targeted service
levels, our colocation customers are offered 24 hour-a-day, seven day-a-week
physical and remote access to our facilities. We offer five options to satisfy
our customers' needs:
 
  - Switched Ethernet Service, which is a 10 megabit per second service
    connection onto our backbone router shared by other customers
 
  - Dedicated Ethernet Service, which is a 10 megabit per second service
    connection directly onto our backbone router not shared with any other
    customers
 
  - Switched Fast Ethernet Service, which is a switched ethernet service with a
    100 megabit per second Internet connection
 
  - Dedicated Fast Ethernet Service, which is a dedicated ethernet service with
    a 100 megabit per second Internet connection
 
  - Gigabit Fast Ethernet Service, which is a switched ethernet service with a
    1,000 megabit per second Internet connection
 
CUSTOMERS
 
We have established a diverse customer base including Internet service and
content providers, businesses, government agencies and educational institutions
to whom we offer a wide range of services including Internet and network
connectivity, value-added and hosting services. In addition, we provide dial-up
Internet access services to consumers. No customer accounted for more than 2.6%
of our revenues in either 1997 or 1998. The revenues derived from our top 10

We aggressively pursue small and medium-sized business customers and seek to
provide them with connectivity and customized, cost-effective network management
solutions. The following are examples of solutions we currently provide to our
customers.
 
WALNUT CREEK CDROM, INCORPORATED: Walnut Creek CDROM, Incorporated, an
Internet-based freeware site, is one of the nation's busiest public FTP sites.
According to Walnut Creek CDROM, more than five
 
                                       40
<PAGE>   45
 
million visitors download the latest computer software, ranging from games to
operating systems, from this location each month. Walnut Creek CDROM needed a
reliable, Tier 1 provider to support its traffic flows, which can often reach 98
megabits per second for a sustained period of time. Walnut Creek CDROM uses our
100 megabits per second dedicated fast ethernet service to connect directly to
our core backbone at our San Francisco network operations center. This high
speed, direct Internet solution meets our customer's bandwidth requirements and
increases network reliability by reducing the number of router hops to the
Internet. We provide the 24 hour-a-day, seven day-a-week network management
required to deliver Walnut Creek CDROM's round-the-clock Internet applications.
 
J. LINNEMAN & CO.: J. Linneman & Co., a reinsurance agency associated with
Lloyd's of London, required a reliable, private data switched network to handle
sensitive and mission-critical information. Without a managed network to
facilitate internal company communication, company officials were concerned that
underwriters could potentially over-insure national clients. Using our wide area
networking services, we developed and deployed a customized data network between
J. Linneman's headquarters in San Francisco and regional offices in Atlanta,
Chicago and Hartford. An Internet connection was also secured for each location.
In order to meet J. Linneman's demand for scalability and cost control, we
provide varying bandwidth to each city, with the option for an increase at any
time.
 
RIVER CITY PETROLEUM: River City Petroleum, Inc., a fleet fueling and wholesale
fuels provider, was listed by the Sacramento Business Journal as one of
Sacramento's "50 Fastest Growing Companies" and the 19th largest private company
in the Sacramento region. The company built a local area network but had little
expertise to install new network elements, nor did they want to oversee the
day-to-day management and administration activities a network requires. Using
our proprietary remote management services, we developed and deployed a
customized solution for River City Petroleum that reduces costly systems
administrator fees and protects the firm's mission-critical data by handing off
the day-to-day management to us. River City Petroleum can now focus on
continuing its acquisition-oriented growth, not its local area network.
 
Our success substantially depends on the continued growth of our customer base
and retention of our customers. Our ability to attract new customers will depend
on a variety of factors, including the willingness of businesses to outsource
their mission-critical networking and Internet operations, the reliability and
cost-effectiveness of our services and our ability to effectively market such
services. Substantially all of our customer contracts have terms ranging from
one to three years.
 
A failure on our part to develop these relationships could materially and
adversely impact our ability to generate increased revenues, which would
negatively affect our financial results. We also intend to significantly
increase our sales and marketing expenditures, which may not necessarily result
in increased sales of our services. For a detailed discussion of the risks, see
"Risk Factors -- Our success depends on our ability to retain existing and
attract new customers" and "-- We are subject to the risks from our lengthy
sales cycle."
 
OUR NETWORK
 
Our network enables us to provide our current service offerings and is the
platform from which we intend to expand our service offerings. Our network is
comprised of several elements, including routers, switches, facilities and clear
channel fiber-optic capacity, which together provide a fast, secure, high
quality and fault tolerant network. In addition, we have both public and private
peering agreements allowing us to connect directly with all major Internet
service providers. The following map illustrates our network and peering
relationships:
 
[Graphics depict a map of United States Entitled "Networks Built for Business"
with CRL logo, reflecting CRL's network connecting cities nationwide, including
symbols designating CRL's Regional Hubs, CRL Points of Presence or Service
Areas, Internet Protocol Backbone and Switched Backbone]
 
                                       41
<PAGE>   46
 
  Network Equipment
 
Our network consists of 23 Cascade data switches and 54 Cisco routers located
throughout our points of presence. Routers are "Layer 3" networking devices,
which must disassemble each packet of data they receive, make a policy-based
routing destination decision according to Internet Protocol-based routing
tables, and then reassemble the packet and send it to the destination determined
by the routing protocol then in effect. These routing protocol tables must be
frequently updated by the router to reflect changes in the tables arising from
numerous events, including changes in peering relationships.
 
Switches are typically "Layer 2" networking devices, which means they make
connections a layer below the Internet. Switches determine routing destinations
based on the Layer 2 addresses attached to each packet without disassembling the
data packets. By operating one layer below the Internet without the need to
disassemble packets, switches can significantly reduce latency and data
degradation, as well as increase security. As a result of the complexity and
multitude of networks that transport information over the Internet, switches are
often an essential component to deliver information in the fastest and most
reliable manner.
 
Unlike many of our competitors, we have invested significant capital in
switches, which are more expensive than routers. Switches, when properly
configured with routers, enhance the speed and reliability of networks by
 
  - minimizing the number of connections, or hops, a data packet must take,
    which minimizes the time required to deliver the packet
 
  - reducing the number of times a packet must be disassembled by routers, which
    reduces the opportunities for router errors
 
  - decreasing the instances where packets must travel over public networks,
    which decreases the likelihood of latency and data degradation
 
Our national network of switches and routers permits us to customize our network
connectivity by creating an efficient "virtual circuit" for each customer, a
logical connection between the physical devices transmitting, directing and
receiving the data packets. The following illustrations show the difference
between a network that utilizes switches and routers to maximize the quality of
network service and a network based solely on routers.
 
[Graphics depicting traditionally routed networks including the transit of a
data packet across different cities in the U.S. requiring multiple hops among
various points from the origin to the destination of the data packet and a
depiction of switched networks including a map of the U.S. overlayed by a cloud
showing a direct transfer of a data packet through this cloud.]
 
Switches have other advantages over routers as well. If a network outage occurs,
our Cascade switches can re-route data between our routers so that our network
does not experience an interruption of service during the outage. This process
allows our routers to forward more packets without making complex routing
decisions. Our Cascade switches are multi-protocol capable, allowing us to
operate Internet Protocol and other protocols as required.
 
  Network Facilities
 
We have constructed a national backbone network with points of presence in 30
cities including 16 of the largest 20 cities in the United States. We control
our points of presence, including our network operations center in San
Francisco, under leases with terms ranging from month-to-month to four years,
that allow us to control the quality and security of the operations. We can
upgrade our points of presence as desired and are able to significantly reduce
the length of time of network interruptions because we control our facilities.
We have points of presence in San Francisco, Los Angeles, San Diego, Phoenix,
Denver, Dallas, Vienna (Virginia), Chicago and 22 other cities.
 
                                       42

Many of our points of presence are located in, or in close physical proximity
to, "carrier hotels." Carrier hotels are facilities where major interexchange
carriers and Internet service providers have physical points of presence. Our
actual location in, or in close proximity to, the same building in which the
switches and routers of these carriers and providers are located offers us the
ability to quickly and easily interconnect our equipment to theirs by our simply
installing a "pipe" connection between our equipment and theirs. Without this
close physical proximity, the services and expense of a third party, like an
incumbent local exchange carrier or competitive access provider, would be
necessary to connect us to the interexchange carrier or other provider. Because
many of these carrier hotels have fully leased their space, we have an advantage
over many of our competitors who are unable to lease space in the facility or in
close enough proximity to the facility and need the services of a third party to
provide similar connectivity.
 
As we expand, we expect to increase our number of points of presence. Each point
of presence is monitored through our network operations center on a 24
hour-a-day, seven day-a-week basis, which allows us to rapidly identify and
resolve any service interruptions. All of our points of presence are connected
directly to local operators including regional Bell operating companies and
competitive local exchange carriers. Where practical, our local connections are
made at the DS-3 level, which allows us to install up to 28 customers at a time
on an expedited basis without the need for any wiring or physical changes within
our point of presence.
 
We currently lease clear channel fiber-optic capacity on networks from companies
such as Qwest Communications Corporation and IXC Communications, Inc. We have
chosen short-term leases of fiber-optic capacity as opposed to acquiring
indefeasible rights of use for fiber-optic capacity due to rapidly declining
bandwidth costs. We believe that our choice has had a significant impact on our
ability to maintain a relatively low cost structure network. Through our leased
fiber-optic cable, we are able to easily create customized data switched
networks for ourselves or others. As we expand and seek additional leased
capacity, we believe that capacity will be available. Several major fiber
construction projects have commenced in the domestic United States, and
frequently the developer of a fiber route will exchange access with other fiber
carriers in a "route swap." Such "route swaps" bring a new vendor of fiber along
a particular route to the marketplace, and ultimately serve to drive the price
of fiber-optic capacity down.
 
Our network operations center located in San Francisco is operated on a 24
hour-a-day, seven day-a-week basis. This network operations center functions
primarily to ensure that our backbone network is operational at an optimal level
and has the ability to ingress and egress traffic. In addition, the center
monitors the connections between the backbone network and the customer. If the
customer's network fails, we notify the customer of their network failure and
begin working immediately to correct the failure.
 
  Peering Relationships
 
We have both public and private peering relationships. A peering relationship
permits the direct connection of two providers without the necessity of a third
party. We believe we were one of the first companies to provide commercial
Internet access to both consumers and corporations. As the Internet and Internet
interexchange points have evolved, we have been well positioned to become and
have become a significant peering partner. We currently have public peering at
the major interexchange points including:
 
  - MAE East in Vienna, Virginia,
 
  - MAE West at Nasa Ames Research Center in Palo Alto, California,
 
  - the Fix West Federal Interconnect Exchange at Nasa Ames Research Center in
    Palo Alto, California,
 
  - the Sprint Network Access Point in Pensauken, New Jersey,
 
  - the AADS Network Access Point in Chicago, Illinois,
 
  - the Pacific Bell Network Access Point in San Francisco, California,
 
  - the Pacbell Switched Multimegabit Data Service Cloud in Northern California,
    and
 
  - the Commercial Internet Exchange router in Santa Clara, California.
 
                                       43
<PAGE>   48
 
As is typical industry practice, we have reciprocal peering relationships with
other Internet service providers that offer significant traffic exchange. Our
open network policy allows us to make cost-based peering decisions between
public and private peering points.
 
Subject to few exceptions, our peering relationships are not subject to any
written agreements. As the Internet has evolved, network service providers have
determined whether they will recognize a second provider as a peer based on the
impact on the first provider of failing to do so. The first provider makes this
determination by analyzing how many customers rely on the second provider as
their sole source of connectivity to the Internet. In many cases, either the
customer has more than one provider that supplies that connectivity or the
second provider relies on another Internet service provider to supply the first
provider's connectivity to the Internet. If the second provider has customers
who look to that provider as their sole source, and the first and second
providers refuse to peer with one another, the portions of each provider's
customer base that are sole source will be unable to connect with each other
over the Internet.
 
As a result of our early involvement in the Internet, we are a Tier 1 Internet
service provider and have peering relationships with other Tier 1 Internet
service providers.
 
SALES AND MARKETING
 
Our sales and marketing objective is to achieve broad market penetration and
increase brand name recognition among small and medium-sized businesses,
Internet service and content providers, government agencies and educational
institutions on a national basis through the expansion of our sales organization
and extensive marketing activities. As of March 15, 1999, we employed 24 persons
in sales and marketing. We have developed a multi-tiered sales strategy to sell
and market to our target markets through direct sales, Internet alliances,
channel relationships and customer referrals.
 
Direct Sales. Our direct sales force currently consists of highly trained
individuals located in San Francisco, California and two other sales offices in
the United States. Substantially all of our sales are currently generated by our
direct sales force. Our sales force is supported in their sales efforts by a
sales engineer and, in many instances, by senior management. We believe that the
integration of our sales engineers with our sales account managers assists both
the establishment of customer relationships as well as the migration of
customers to increased use of our services through cross selling of our
value-added services. We have developed programs to attract and retain high
quality, motivated sales representatives with the necessary technical skills,
consultative sales experience and knowledge of their local markets. These
programs include technical and sales process training and instruction in
consultative selling techniques. We have also developed sales compensation plans
that provide significant incentives for exceeding performance targets. We are
actively seeking to expand our direct sales force and sales engineering staff.
 
Our direct sales process consists of a multifaceted approach to lead generation
and includes direct mail, advertising, Web-based marketing, networking and cold
calling. We target small and medium-sized businesses nationwide with particular
emphasis on those geographic areas where we have points of presence. Prospects
are qualified through a needs-based consultative sales process and, depending
upon the complexity of the client need, sales engineers and senior management
are called upon to develop solutions.
 
Develop Channel Relationships. We are in the process of developing relationships
with potential channel partners including hardware vendors, value-added
resellers, system integrators and Web hosting companies to leverage their sales
organizations. We believe that by leveraging the sales forces of these
companies, we can attract customers in a cost-effective manner, as well as
provide co-branded Internet and network management service offerings for our
channel partners. We are actively engaged in hiring experienced channel managers
to focus exclusively on developing these relationships.
 
By providing Internet and network management solutions, our partners can satisfy
the demands of their customers, as well as create opportunities for new
business. We will offer the expertise involved with a complex networking
infrastructure that will allow our partners to focus on their own areas of
expertise. This relationship will provide our partner with the tools needed to
bundle Internet access with a variety of
 
                                       44
<PAGE>   49
 
services provided by us or our partner, and gain the competitive edge needed to
attract and maintain more customers, increase market share and grow.
 
Because we realize that most companies have specific operating requirements, we
have designed a flexible program to accommodate specific needs. We will both
provide the necessary network connectivity and serve as a technical resource for
our partners. Engineers in our networking operating center monitor the network
around the clock to ensure the highest quality Internet, remote management
service, and hosting services and technical support for our partner and its
customers. Instead of spending time and money building a national network
infrastructure, partners will be able to simply add Internet, remote management
service and hosting services to their existing products by becoming part of our
network. By bundling Internet, remote management service and hosting services
with existing products, the partner will be able to offer a high quality network
connection to the Internet with the ease of one bill and one point-of-contact
for customers.
 
Marketing. Our marketing program is intended to build national and local
strength and brand awareness. We use print advertising and direct mail in
targeted markets and publications to enhance awareness and acquire leads for our
direct sales force. We also use telemarketing programs, Web marketing and joint
promotional efforts.
 
CUSTOMER SUPPORT
 
We offer a high level of customer service and quality assurance by understanding
the technical requirements and business objectives of our customers and
addressing their needs proactively on an individual basis. By working closely
with our customers, we are able to enhance the performance of our customers'
Internet and network operations, avoid downtime, rapidly resolve problems and
make appropriate adjustments in services as customer needs change over time. We
work with our customers over time to ensure that we are offering the appropriate
types and quality of service. As of March 15, 1999, we had 15 employees
dedicated to customer service and quality assurance.
 
Upon receipt of a signed sales contract, the salesperson prepares a sales order
form and sends it to our provisioning department which, after initial review,
forwards the sales order to our finance department for approval and set up on
the billing system.
 
Within the provisioning department the sales order is logged into a tracking
system that is reviewed by management on a weekly basis. The provisioning
department arranges all internal and external activities to complete the
installation of the sales order. As necessary, they arrange for purchase,
delivery and setup of equipment, arrange for necessary circuits with various
telecommunications vendors, and complete necessary changes to our network
through our engineering department.
 
Upon completion of all necessary installations, the customer is contacted for
testing and acceptance. Customer information is entered into an operations
database and our finance department is notified to begin billing.
 
Ongoing customer service is provided by our technical support group. Our network
operations center operates and is available for technical support 24
hours-a-day, seven days-a-week, 365 days-a-year. They monitor customer circuits
real-time on the same basis. As problems are identified or customer calls are
received they are logged into a trouble ticket system and worked through to
resolution. Inquiries can be accepted by voice or e-mail and are typically
answered within a few minutes or hours of receipt. Resolution times vary
depending upon the problem's severity and complexity. Resolution times that
exceed a few hours are escalated to management.
 
Our enhanced customer support systems monitor and track support questions from
our customers. These systems were developed to help the network engineers track
problems efficiently and reliably. They provide an accurate history of each
account enabling the engineers to quickly access support inquiries and provide
us with valuable historical data about each account. Every time a support
question is called in, a historical record, commonly referred to as a
"trouble-ticket," is opened. Until the problem is resolved, the trouble-
 
                                       45
<PAGE>   50
 
ticket remains open. When necessary, the trouble-ticket is escalated in order to
reach the fastest possible resolution. The escalation chart is made available to
our customers.
 
COMPETITION
 
Our competitors generally may be divided into four principal groups:
 
  - telecommunications carriers including regional Bell operating companies,
    often referred to as "RBOCs"
 
  - Internet service providers
 
  - network and system integrators
 
  - online network service providers
 
Telecommunications Carriers. Many long distance companies including AT&T
Corporation, Cable & Wireless P.L.C., Sprint Corporation, MCI WorldCom, Inc.,
Qwest Communications International Inc., Level 3 Communications Inc., IXC
Communications, Inc. and Frontier Corporation offer Internet access services and
network services. Recent reforms in federal regulation of the telecommunications
industry have created greater opportunities for incumbent local exchange
carriers such as PacBell Internet, and competitive local exchange carriers such
as WinStar Communications, Inc., to enter the Internet connectivity market. We
believe that there is a move toward horizontal integration by these kinds of
carriers through acquisitions of, joint ventures with, or the wholesale purchase
of connectivity from, Internet service providers in order to meet the Internet
connectivity requirements of their business customers. Accordingly, we expect
that we will experience increased competition from the traditional
telecommunications carriers. In addition to their greater network coverage,
market presence and financial, technical and personnel resources, many of these
telecommunications carriers also have large existing commercial customer bases.
 
Internet Service Providers. Our competitors include Internet service providers
with a national or global presence that focus on business customers, such as
PSINet, Inc. and UUNET Technologies, Inc. We also compete with Internet service
providers that cluster in major markets and regional Internet service providers
that have facilities in key metropolitan areas, including Verio, Inc., and
specialized Internet service providers such as Concentric Network Corporation,
Exodus Communications, Inc., AboveNet Communications Inc. and AppliedTheory
Corporation, as well as emerging Internet service providers. While we believe
that our state-of-the-art network infrastructure, quality customer service and
proactive support teams distinguish us from most Internet service providers,
many of these competitors have greater financial, technical, and marketing
resources, larger customer bases, greater name recognition and more established
relationships in the industry.
 
Network and System Integrators. We compete with large information technology
outsourcing firms such as the Big 5 accounting firms, EDS Corp., Perot Systems
Corporation and similar firms. These firms tend to focus on large customers who
outsource entire information technology functions or re-engineer their
information technology infrastructure. We believe that we are distinguished from
these competitors because we specialize in Internet Protocol-based integration
for the businesses and government agencies focused on Internet and other network
operations. We also compete with smaller network and systems integrators.
However, we believe that our expertise with large and complex systems, our
methodology and our ability to offer one-stop solutions for integration, data
center services and network connectivity set us apart from this segment of the
competition.
 
Online Network Service Providers. In providing consumer Internet access, we
compete with online network service providers such as America Online,
Compuserve, MSN (The Microsoft Network) and Prodigy Communication Corporation.
The services offered by these companies often includes access to content
specific to each company. While we believe that our consumer products are
competitively priced and that our support and proactive network maintenance give
us an advantage over our competitors, many of these competitors have greater
financial, technical and marketing resources, larger customer bases, greater
name recognition, wider customer reach and more established relationships in the
industry.
 
                                       46
<PAGE>   51
 
We believe the primary competitive factors in our markets are:
 
  - a reliable and powerful network infrastructure
 
  - a broad range of services and technical expertise
 
  - quality of customer service
 
  - experienced and knowledgeable sales force and engineers
 
Many of our competitors may be able to develop and expand their communications
and network infrastructures more quickly, adapt more swiftly to new or emerging
technologies and changes in customer requirements, take advantage of acquisition
and other opportunities more readily, and devote greater resources to the
marketing and sale of their services than we can. In addition, we believe
competition in our markets will intensify as new competitors enter our markets
which have no significant barriers to entry. In addition, some of our
competitors may bundle other services and products, offer their services at more
attractive prices, or offer other high speed data services using alternative
delivery methods.
 
We do not currently compete internationally. If the ability to provide Internet
access internationally becomes a competitive advantage in the Internet access
industry, we may be at a competitive disadvantage relative to our competitors.
 
For more information concerning the competition we face and the factors
affecting our ability to compete, see "Risk Factors -- The markets for our
services is characterized by many competing technologies, and the technologies
on which our services are based may not compete effectively" and "-- We may have
to reduce the cost of our services to remain competitive."
 
INTELLECTUAL PROPERTY RIGHTS
 
We believe our success depends more upon our technical expertise than our
proprietary rights. We rely upon a combination of copyright, trademark and trade
secret laws and contractual restrictions to protect our proprietary technology
and rights in our services. We have no patented technology that would preclude
or inhibit competitors from entering our market. We have entered into
confidentiality and invention assignment agreements with certain of our
employees, and nondisclosure agreements with our suppliers, distributors and
appropriate customers to control access to and disclosure of our proprietary
information. Despite these precautions, a third party could potentially copy or
otherwise obtain and use our products or technology without authorization or to
develop similar technology independently. We cannot assure you that such
measures have been, or will be, adequate to protect our proprietary technology
or deter third party development of similar technologies. We also rely on
certain technologies that we license from third parties such as network
management software. We do not license any other technology that is not
generally available. These third-party technology licenses may not always
continue to be available to us on commercially reasonable terms. The loss of
such technology could require us to obtain substitute technology of lower
quality or performance standards or at greater cost, which could affect us in a
material adverse manner. To date, we have not been notified that we infringe the
proprietary rights of third parties, but there can be no assurance that third
parties will not claim infringement by us. We expect that participants in our
markets will be increasingly subject to infringement claims as the number of
technologies and competitors in our industry grows. Any such claim, whether
meritorious or not, could be time consuming, result in costly litigation, cause
service delays or require us to enter into royalty or licensing agreements. Such
royalty or licensing agreements might not be available on terms acceptable to us
or at all. As a result, any such claim could have a material adverse effect upon
our business, results of operations and financial condition.
 
GOVERNMENT REGULATION
 
Currently only a small body of laws and regulations directly apply to access to
or commerce on the Internet. However, due to the Internet's increasing
popularity and use, laws and regulations may be adopted at the international,
federal, state and local levels with respect to the Internet, covering issues
such as user privacy, freedom of expression, pricing, characteristics and
quality of products and services,
 
                                       47
<PAGE>   52
 
taxation, advertising, intellectual property rights, information security and
the convergence of traditional telecommunications services with Internet
communications. Moreover, a number of laws and regulations have been proposed
and are currently being considered by federal, state and foreign legislatures
with respect to such issues. The nature of any new laws and regulations and the
manner in which existing and new laws and regulations may be interpreted and
enforced cannot be fully determined. The adoption of any future laws or
regulations might decrease the Internet's growth, decrease demand for our
services, impose taxes or other costly technical requirements or otherwise
increase the cost of doing business or in some other manner have a material
adverse effect on us. In addition, applicability to the Internet of existing
laws governing issues such as property ownership, copyrights and other
intellectual property issues, taxation, libel, obscenity and personal privacy is
uncertain. As our services are available over the Internet in multiple states,
and as we facilitate sales by our customers to end users located in such states,
such jurisdictions may claim that we are required to qualify to do business as a
foreign corporation in each such state. Any such new legislation or regulation,
or the application of laws or regulations from jurisdictions whose laws may not
currently apply to our business, could have a material adverse effect on us.
 
The Telecommunications Act of 1996 imposes criminal liability on persons sending
or displaying in a manner available to minors indecent material on an
interactive computer service such as the Internet and on an entity knowingly
permitting facilities under its control to be used for such activities. Sections
of the Communications Decency Act of 1996 that, among other things, proposed to
impose criminal penalties on anyone distributing "indecent" material to minors
over the Internet, were held to be unconstitutional by the United States Supreme
Court. Legislation similar to the Communications Decency Act could subject us
and/or our customers to potential liability, which in turn could have an adverse
effect on us. Additionally, the Child Online Protection Act of 1998 prohibits
and imposes criminal penalties and civil liability on anyone engaged in the
business of selling or transferring, by means of the World Wide Web, material
that is harmful to minors without restricting access to such material by persons
under seventeen years of age. Numerous states have adopted or are currently
considering similar types of legislation. The imposition upon us, our customers
or other persons of potential liability for such materials carried on or
disseminated through our systems could require us to implement measures to
reduce our exposure to such liability. Such measures may require the expenditure
of substantial resources or the discontinuation of certain product or service
offerings. Further, the costs of defending against any such claims and potential
adverse outcomes of such claims could have a material adverse effect on us. The
Child Online Protection Act has been challenged by civil rights organizations in
part on the grounds that it violates the First Amendment. A United States
District Court has preliminary enjoined enforcement of the law until final
resolution of the case. A similar statute was held unconstitutional by the
United States Supreme Court in 1997.
 
The law relating to the liability of online service providers, private network
operators and Internet service providers for information carried on or
disseminated through the facilities of their networks is continuing to evolve
and remains unsettled. In the past, at least one court has ruled that Internet
service providers could be found liable for copyright infringement as a result
of information disseminated through their networks. We cannot assure you that
similar claims will not be asserted in the future. Federal laws have been
enacted, however, which, under certain circumstances, provide Internet service
providers with immunity from liability for information that is disseminated
through their networks when they are acting as mere conduits of information. A
Federal Court of Appeals has recently held that the Telecommunications Act
creates immunity from liability on the part of Internet service providers for
libel claims arising out of information disseminated over their services by
third-party content providers. In addition, the Digital Millennium Copyright
Act, enacted in 1998, creates a safe-harbor from copyright infringement
liability for Internet service providers that meet certain requirements. These
requirements include certain technical measures and registering with the
Copyright Office the identity of the provider's Designated Infringement Agent
who is to receive notice of any claims of copyright infringement. We cannot
assure you, however, that the Digital Millennium Copyright Act or any other
legislation will protect us from copyright infringement liability. We maintain
general liability insurance. However, any imposition of liability on us for
alleged negligence, intentional torts such as infringement, or other liability
could have a material adverse effect on us.

Both the provisioning of Internet access service and the provisioning of
underlying telecommunications services are affected by federal, state and local
regulation. The Federal Communications Commission exercises jurisdiction over
all facilities of, and services offered by, telecommunications carriers to the
extent that they involve the provision, origination or termination of
jurisdictionally interstate or international communications, including by
competitive local exchange carriers. The state regulatory commissions retain
jurisdiction over the same facilities and services to the extent they involve
origination or termination of jurisdictionally intrastate communications. In
addition, as a result of the passage of the Telecommunications Act, state and
federal regulators share responsibility for implementing and enforcing the
domestic pro-competitive policies of the Telecommunications Act. In particular,
state regulatory commissions have substantial oversight over the provision of
interconnection and non-discriminatory network access by incumbent local
exchange carriers. Municipal authorities generally have some jurisdiction over
access to rights of way, franchises, zoning and other matters of local concern.
 
Government agencies do not regulate Internet operations distinctly from their
regulation of businesses generally. However, the Federal Communications
Commission continues to review its regulatory position on the usage of the basic
network and communications facilities by Internet and other network service
providers. In an April 1998 report, the Federal Communications Commission
determined that Internet service providers should not be treated as
telecommunications carriers and should consequently not regulated. However, this
report stated that it expected the regulatory status of Internet service
providers in the future to continue to be uncertain. The report concluded that
certain services offered over the Internet, such as phone-to-phone Internet
protocol telephony, may be functionally indistinguishable from traditional
telecommunications service offerings, and their non-regulated status may have to
be re-examined.
 
Changes in the regulatory structure and environment affecting the Internet
access market, including regulatory changes that directly or indirectly affect
telecommunications costs or increase the likelihood of competition from regional
Bell operating companies or other telecommunications companies, could have an
adverse effect on our business. Although the Federal Communications Commission
has decided not to allow local telephone companies to impose per-minute access
charges on Internet service providers, and that decision has been upheld by the
reviewing court, further regulatory and legislative consideration of this issue
is likely. In addition, some telephone companies are seeking relief through
state regulatory agencies. Such rules, if adopted, are likely to have a greater
impact on consumer-oriented Internet access providers than on business-oriented
Internet service providers, such as us. Nonetheless, the imposition of access
charges would affect our costs of serving dial-up customers and could have a
material adverse effect on us.
 
We have recently received approval to operate as a competitive local exchange
carrier in California and intend to apply to receive similar status in other
states. Where we have competitive local exchange carriers status, regional Bell
operating companies are obligated to provide us with local connectivity loops at
prices that are substantially below the prices paid by Internet and other
network service providers that are not competitive local exchange carriers. As a
provider of domestic basic telecommunications services, particularly competitive
local exchange services, we could become subject to further regulation by the
Federal Communications Commission and/or other regulatory agencies, including
those at the state and local levels. The Telecommunications Act has caused
fundamental changes in the markets for local exchange services. In particular,
the Telecommunications Act and the Federal Communications Commission rules
issued pursuant to it mandate competition in local markets and require that
incumbent local exchange carriers interconnect with competitive local exchange
carriers. Under the provisions of the Telecommunications Act, the Federal
Communications Commission and state public utility commissions share
jurisdiction over the implementation of local competition, the Federal
Communication Commission was required to promulgate general rules and the state
commissions were required to arbitrate and approve individual agreements.
However, the Federal Communication Commission interconnection rules implementing
the Telecommunications Act were appealed and, in the case of the "national
pricing" rules, vacated. The Supreme Court has agreed to review this lower court
decision and heard oral arguments on this matter on October 13, 1998. Pending
the Supreme Court's decision, state public utility commissions are free to
develop independent pricing policies for interconnection, unbundled access,
resale, and transport and termination of local telecommunications traffic.
 
                                       49
<PAGE>   54
 
A critical issue for competitive local exchange carriers is the right to receive
reciprocal compensation for the transport and termination of Internet traffic.
We believe that, under the Telecommunications Act and current Federal
Communications Commission rules, competitive local exchange carriers are
entitled to receive reciprocal compensation from incumbent local exchange
carriers. However, some incumbent local exchange carriers have disputed payment
of reciprocal compensation for Internet traffic, arguing that Internet service
provider traffic is not local traffic. Most states have required incumbent local
exchange carriers to pay Internet service providers reciprocal compensation.
However, federal regulators and some state regulators are currently considering
the proper jurisdictional classification of local calls placed to an Internet
service provider and whether Internet service provider calling triggers an
obligation to pay reciprocal compensation. On October 30, 1998, the Federal
Communications Commission determined that dedicated digital subscriber line
service is an interstate service and properly tariffed at the interstate level.
On February 25, 1999, the Federal Communications Commission ruled that calls to
Internet service providers for Internet access were long distance, not local,
calls. However, the ruling upheld existing reciprocal compensation agreements in
some states, including California. If incumbent local exchange carriers charge
fees for carrying Internet traffic and Internet access becomes more expensive,
this ruling may have an adverse effect on our potential future revenues as well
as increase our costs.
 
As we become a competitor in local exchange markets, we will become subject to
state requirements regarding provision of intrastate services. These
requirements may include the filing of tariffs containing rates and conditions.
As a new entrant without market power, we expect to face a relatively flexible
regulatory environment. Nevertheless, it is possible that some states could
impose a variety of requirements on our operations, such as the approval of the
public utilities commission for the issuance of debt or equity or other
transactions that would result in a lien on our property used to provide
intrastate services.
 
EMPLOYEES
 
As of March 15, 1999, we had 59 employees, of which 24 were employed in sales
and marketing, eight were assigned to engineering and service development, 15
were employed in customer service and technical support, and 12 were in finance
and administration. We believe that our future success will depend in part upon
our continued ability to attract, hire and retain qualified personnel. The
competition for such personnel is intense, and we may not be able to identify,
attract and retain such personnel in the future. None of our employees is
represented by a labor union, and management believes that our employee
relations are good.
 
FACILITIES
 
Our executive offices are located in San Francisco, California and consist of
approximately 4,650 square feet that are leased pursuant to an agreement that
expires in May 1999 with a three year renewal option. Additionally, we sublease
additional offices in San Francisco, California of approximately 3,500 square
feet pursuant to an agreement that expires in September 1999. We also have a
network operating center in San Francisco of approximately 4,000 square feet
under a lease expiring in 2005. Beginning in the second quarter 1999, we intend
to commence relocating and consolidating our San Francisco operations to a
single site. We intend to complete the relocation and consolidation in the
fourth quarter of 1999. We are also currently in negotiations with the lessor of
our San Francisco network operating center to lease additional space. We also
intend to complete the expansion of our main operational center in Sacramento,
California in the fourth quarter of 1999. This Sacramento facility consists of
4,000 square feet under a lease agreement that expires in 2001. In addition, we
lease approximately 1,100 square feet in Vienna, Virginia (a major network
access point often referred to as MAE East) under an agreement that expires in
2000 with a five year renewal option. We also lease approximately 1,400 square
feet in the One Wilshire Building in Los Angeles under an agreement that expires
in 2001. We lease facilities in 26 other cities throughout the United States for
our sales offices and regional network operating centers.

any particular non-employee directors or all non-employee directors at the

executive officers, including Mr. Couch in his capacity as President and Chief
Executive Officer. Upon completion of this offering, the Compensation Committee

directors or compensation committee of any other company, nor has any such
interlocking relationship existed in the past.

(1)  There was no public trading market for the common stock as of December 31,
     1998. Accordingly, these values have been calculated on the basis of fair
     market value of common stock of $5.10 per share. Therefore, the value of
     options in the table is calculated based on the $5.10 per share value, less
     the applicable exercise price per share, multiplied by the number of shares
     underlying these options.
 
401(K) PLAN
 
We have an employee profit sharing plan that is intended to qualify as a
deferred salary arrangement under Section 401(k) of the Internal Revenue Code.
Under our 401(k) Plan, our officers and other employees may elect to defer up to
15% of their compensation, subject to limitations under the Internal Revenue
Code. We may from time to time also make contributions on behalf of each officer
or other employee, which contributions vest depending on the length of
employment of each respective officer or employee. Amounts deferred are
deposited by us in a trust account for distribution to employees upon
retirement, attaining age 65, permanent disability, death, termination of
employment or the occurrence of conditions constituting extraordinary hardship.
We have not made matching contributions on behalf of our officers and other
employees in the past.
 
STOCK OPTIONS
 
  1997 Equity Incentive Plan
 
On August 8, 1997, our Board of Directors adopted, and our stockholders
approved, the CRL Network Services, Inc. 1997 Equity Incentive Plan. The 1997
Equity Incentive Plan provides for the grant of incentive and non-statutory
options, restricted stock or stock bonuses to purchase up to an aggregate of the
number of shares of common stock equal to 10% of the total number of shares of
our authorized common stock. Incentive stock options can be granted only to our
full-time employees, including officers and directors who are also employees,
while non-statutory stock options, restricted stock and stock bonuses can be
granted to our employees, officers and directors, consultants and advisors.
Participants in the 1997 Equity Incentive Plan are selected by our Board of
Directors, or by a committee of directors selected by the Board of Directors.
The Board of Directors or the committee is empowered to determine the terms and
conditions of each award granted under the 1997 Equity Incentive Plan, subject
to limitations including that no option can have a term in excess of ten years,
or five years if granted to an employee owning more than 10% of our outstanding
common stock. In the event of:
 
  - a merger or consolidation in which we are not the surviving corporation
    (other than a merger or consolidation with a wholly-owned subsidiary or a
    reincorporation in a different jurisdiction)
 
  - our dissolution or liquidation
 
  - a sale of all or substantially all of our assets
 
  - any other transaction that qualifies as a "corporate action" under Section
    424(a) of the Internal Revenue Code
 
                                       54
<PAGE>   59
 
the number of vested shares under all options granted pursuant to the 1997
Equity Incentive Plan will increase as if the holder had remained our employee
for an additional one year from the date of such event. The Board of Directors
may amend or modify the 1997 Equity Incentive Plan at any time subject to any
required shareholder approval. The 1997 Equity Incentive Plan will terminate on
the earliest of:
 
  - August 7, 2007
 
  - the date in which all shares available for issuance under the 1997 Equity
    Incentive Plan have been issued as fully-vested shares
 
  - the termination of all outstanding options in connection with a change of
    control in which the successor corporation does not assume the 1997 Equity
    Incentive Plan
 
As of December 31, 1998, options to purchase 952,987 shares, at a weighted
average exercise price of $2.11, were outstanding under the 1997 Equity
Incentive Plan. There have been no restricted stock awards or stock bonuses
awarded. We do not intend to make any further option grants under this plan.
 
  1999 Stock Incentive Plan
 
On March 18, 1999, our Board of Directors adopted, and our stockholders
approved, the CRL Network Services, Inc. 1999 Stock Incentive Plan. The 1999
Stock Incentive Plan does not limit any award to any specified form or
structure. The types and amount of awards will be determined at the discretion
of the Board of Directors or committee of the Board of Directors empowered to
administer the 1999 Stock Incentive Plan. The maximum number of shares of common
stock that may be issued under the 1999 Stock Incentive Plan is 1,000,000
shares. If incentive stock options are issued, these options must comply with
Section 422 of the Internal Revenue Code. Participants in the 1999 Stock
Incentive Plan are selected by a committee of directors selected by the Board of
Directors as a whole, each member of which must be a "non-employee director" as
this term is defined under the Securities Exchange Act of 1934, as amended. This
committee is also empowered to determine the terms and conditions of each option
or other stock-based award granted under the 1999 Stock Incentive Plan, subject
to the limitations regarding incentive stock options imposed by the Internal
Revenue Code. The Board of Directors may amend or modify the 1999 Stock
Incentive Plan at any time subject to any required shareholder approval. The
1999 Stock Incentive Plan will terminate on March 17, 2009. There are currently
no options or other awards outstanding under the 1999 Stock Incentive Plan.
 
EMPLOYMENT AGREEMENTS
 
We entered into an employment agreement with James G. Couch, our President and
Chief Executive Officer, on March 15, 1999. Under the terms of this employment
agreement, Mr. Couch will receive an annual base salary of $320,000, which may
be increased at the discretion of the Board of Directors, and at the discretion
of the Board of Directors, a bonus. The term of this employment agreement ends
on February 28, 2002, and is automatically renewable for consecutive one-year
periods unless advance notice is given by either party. We may terminate Mr.
Couch or Mr. Couch may voluntarily resign at any time. If Mr. Couch is
terminated by us without cause, he will by entitled to receive twelve months'
salary, payable in equal monthly installments over the twelve month period
following termination. We are not obligated to pay any specified amount if we
terminate Mr. Couch for cause.
 
In connection with our merger with Integral Networking Corporation, we entered
into an employment agreement and a non-competition agreement with Robert L.
Ross, Integral's President, to continue to serve as President of Integral
Networking Corporation, our wholly-owned subsidiary. The employment agreement's
term expires December 21, 2000. Mr. Ross receives a specified salary and a bonus
based upon targeted personal and company performance. We may terminate Mr. Ross
at any time upon written notice. Mr. Ross may terminate his employment with us
if we fail to cure any breach within 30 days following written notice from him
to us describing the breach. In the event that we terminate Mr. Ross's
employment without cause before the end of its term, we are obligated to pay Mr.
Ross his salary until the end of the term or for three months, whichever is
less.

LIMITATION OF LIABILITY AND INDEMNIFICATION
 
Our Certificate of Incorporation and Bylaws require us to indemnify our
officers, directors, employees and other agents to the full extent permitted by
law, including those circumstances in which indemnification would otherwise be
discretionary. Delaware law provides that a corporation's certificate of
incorporation may contain a provision eliminating or limiting the personal
liability of a director for monetary damages for breach of their fiduciary
duties as directors, except for liability for any breach of their duty of
loyalty to the corporation or its stockholders, acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
unlawful payments of dividends or unlawful stock repurchases or redemptions as
provided in Section 174 of the Delaware General Corporation Law or any
transaction from which the director derived an improper personal benefit. Our
Bylaws also permit us to advance expenses incurred by an indemnified director or
officer in connection with the defense of any action or proceeding arising out
of such director's or officer's status or service as one of our directors or
officers upon any undertaking by such director or officer to repay such advances
if it is ultimately determined that such director or officer is not entitled to
such indemnification. In addition, our Certificate of Incorporation expressly
authorizes the use of indemnification agreements. We currently have no
indemnification agreements with our officers, directors or employees.
 
CERTAIN TRANSACTIONS
 
We are party to an airplane leasing agreement with FBN Holding Corp., the sole
stockholder of which is James G. Couch, our President and Chief Executive
Officer. Under the terms of this agreement, we can elect to lease aircraft from
FBN on an hourly basis at FBN's then prevailing rate, which includes, without
additional charge, all fuel, insurance, repairs and maintenance. Changes in the
FBN prevailing hourly rate require 30 days written prior notice to us. Either
party may terminate the lease upon 15 days prior notice. During 1998, we paid
FBN an aggregate of approximately $144,000 for our use, at various times during
the year, of an airplane owned by FBN. We believe the rates charged by FBN are
equivalent to the rates we could obtain from unaffiliated third parties. We have
sent written notice to FBN terminating this airplane leasing agreement effective
April 30, 1999.
 
In August 1995, we made a loan in the amount of $106,000 with an interest rate
of 7.5% to Mr. Couch. The promissory note delivered to us specified that the
entire principal amount plus accrued interest was to be repaid by July 10, 2000.
During 1998, the stockholder repaid the entire remaining amount outstanding
under the promissory note.
 
We have employment agreements with Messrs. Couch and Ross. See
"Management -- Employment Agreements."
 
All future transactions among us, our directors, principal stockholders and
their affiliates will be approved by a majority of the Board of Directors,
including a majority of the independent and disinterested directors.

                          DESCRIPTION OF CAPITAL STOCK
 
Upon completion of this offering, our authorized capital stock will consist of
          shares of common stock, $.01 par value, and           shares of
preferred stock, $.01 par value. The description of our capital stock below and
certain provisions of our charter documents is not complete and is qualified by
our Certificate of Incorporation and Bylaws, which are included as exhibits to
the Registration Statement that this prospectus is a part of, and by applicable
provisions of the Delaware General Corporation Law.
 
COMMON STOCK
 
As of March 15, 1999, there were 18,978,833 shares of common stock outstanding
that were held of record by four stockholders. Upon completion of this offering,
there will be                     shares of our common stock outstanding
assuming no exercise of the underwriters' over-allotment option and no exercise
of outstanding options. Holders of the common stock are entitled to one vote per
share on each matter submitted to a vote of our stockholders. Cumulative voting
for the election of directors is not authorized by our Certificate of
Incorporation, which means that the holders of a majority of the shares voted
can elect all of the directors then standing for election. Subject to
preferences that may be applicable to the holders of any outstanding series of
our preferred stock, each holder of common stock is entitled to receive
dividends, if any, as may be declared by our Board of Directors out of funds
legally available for the payment of dividends. We have not granted dividends in
the past and have no current plans to do so in the future. See "Dividend
Policy." Upon our liquidation, dissolution or winding up, our common
stockholders are entitled to share ratably in all of our assets which are
legally available for distribution, after payment of all debts and other
liabilities and the liquidation preference of any outstanding series of
preferred stock. Holders of common stock have no preemptive, subscription,
redemption or conversion rights. The outstanding shares of common stock are, and
the shares to be sold by us in the offering will be, when issued and delivered,
validly issued, fully-paid and non-assessable under the Delaware General
Corporation Law.
 
PREFERRED STOCK
 
As of March 15, 1999, no shares of preferred stock are outstanding. Our Board of
Directors is authorized, subject to any limitations of the Delaware General
Corporation Law, but without further vote or action by our stockholders, to
issue preferred stock in one or more series. The Board of Directors can
establish the number of shares of each series, to fix the designations, powers,
preferences and rights of the shares of each such series and any qualifications,
limitations or restrictions of the preferred stock, and to increase or decrease
the number of shares of any such series, but not below the number of shares of
such series then outstanding. The Board of Directors may authorize the issuance
of preferred stock with voting or conversion rights that could adversely affect
the voting power or other rights of the holders of common stock. While providing
flexibility in connection with possible acquisitions and other corporate
purposes, the issuance of preferred stock may have the effect of delaying,
deferring or preventing a change in control of our company. We have no current
plans to issue any shares of preferred stock.
 
CERTAIN PROVISIONS IN OUR CERTIFICATE OF INCORPORATION AND BYLAWS
 
  Stockholder Meetings
 
Our Bylaws provide that any action required to be taken or that may be taken at
any meeting of our stockholders may only be taken at a meeting of stockholders
and may not be taken by the written consent of the stockholders. Special
meetings of stockholders may only be called by the Board of Directors, the
Chairman of the Board or the President and only such business brought forth by
or at the direction of the Board of Directors or the stockholders may be
conducted. If a stockholder wishes to propose an item for consideration at any
meeting, the stockholder must give written notice to us not less than 90 days
before the meeting or, if later, the tenth day following the date of the first
public announcement of the meeting, or such other date as is necessary to comply
with applicable federal proxy solicitation rules and other regulations.
 
                                       58
<PAGE>   63
 
  Board of Directors
 
Our Bylaws provide that the number of directors may not be less than three nor
more than seven until changed by an amendment duly adopted by the Board of
Directors or stockholders. The Bylaws further provide that the exact number of
directors shall be fixed from time to time, within such range, by the Board of
Directors. Currently, the number of directors is fixed at                . The
Bylaws provide that the Board of Directors will be divided into three classes of
directors, which serve for staggered three-year terms. The Bylaws do not provide
for cumulation of stockholder votes in the election of directors. According to
the Bylaws, each director may be removed only for cause and only by the
affirmative vote of at least 80% of the outstanding shares of common stock. The
Bylaws provide that nominations for election of directors may be made by the
Board of Directors or any stockholder entitled to vote in the election of
directors. If a stockholder wishes to nominate a director, the stockholder must
give written notice to us not less than 90 days before the meeting or, if later,
the tenth day following the date of the first public announcement of the
meeting.
 
  Amendment of Our Charter Documents
 
Our Certificate of Incorporation may not be amended without the approval the
holders of a majority of our outstanding voting shares or the approval of at
least a majority of our directors. Our Bylaws contain provisions requiring the
affirmative vote of at least 80% of outstanding shares of common stock to amend,
alter or repeal the provisions of the Bylaws relating to the calling of special
meetings of stockholders, advance notice of stockholder business or nominees,
removal of directors or stockholder action without a meeting.
 
These provisions of our charter documents may delay, defer or prevent a change
in control without further action by our stockholders, may discourage bids for
the common stock at a premium over the market price of the common stock and may
adversely affect the market price of the common stock.
 
  Effect of Delaware Anti-takeover Statute
 
We are subject to Section 203 of the Delaware General Corporation Law which,
subject to certain exceptions, prohibits a Delaware corporation from engaging in
any "business combination" which includes a merger or sale of more than 10% of
the corporation's assets, with any interested stockholder for a period of three
years following the date that such stockholder became an interested stockholder,
unless:
 
  - before such date, the board of directors of the corporation approved either
    the business combination or the transaction which resulted in the
    stockholder becoming an interested stockholder;
 
  - upon completion of the transaction which resulted in the stockholder
    becoming an interested stockholder, the interested stockholder owned at
    least 85% of the voting stock of the corporation outstanding at the time the
    transaction commenced, excluding those shares owned by persons who are
    directors and also officers; or
 
  - on or after such date, the business combination is approved by the board of
    directors and authorized at an annual or special meeting of stockholders,
    and not by written consent, by the affirmative vote of at least two-thirds
    of the outstanding voting stock which is not owned by the interested
    stockholder.
 
In general, Section 203 defines an "interested stockholder" as any entity or
person beneficially owning 15% or more of the outstanding voting stock of the
corporation or any entity or person affiliated with or controlling or controlled
by such entity or person. See "Risk Factors -- Anti-takeover provisions could
negatively impact our stockholders."

                        SHARES ELIGIBLE FOR FUTURE SALE
 
Prior to this offering, there has been no market for our common stock. Future
sales of substantial amounts of our common stock in the public market could
adversely affect prevailing market prices.
 
Upon completion of this offering, there will be           shares of our common
stock outstanding assuming no exercise of the underwriters' over-allotment
option and no exercise of outstanding options. Of these shares, the
shares sold in this offering will be freely tradable without restriction or
further registration under the Securities Act, except for any such shares held
by our "affiliates" (as defined below). The remaining             shares held by
existing stockholders are "restricted securities" as that term is defined in
Rule 144 under the Securities Act. Restricted securities and any shares
purchased in the offering by one of our "affiliates" may not be sold in the
public market without registration under the Securities Act or in compliance
with an applicable exemption from registration as provided in Rule 144 or 701
under the Securities Act, which rules are summarized below.
 
In general, under Rule 144 as currently in effect, a person or persons whose
shares are aggregated who has beneficially owned shares of our common stock for
at least one year including the holding period of any prior owner other than any
of our "affiliates," or who is one of our "affiliates," is entitled to sell
within any three-month period a number of shares or, in the case of an
"affiliate," a number of such restricted securities and shares purchased in the
public market, that does not exceed the greater of:
 
  - 1% of the shares of our common stock then outstanding, equaling
    approximately             shares immediately after this offering, or
 
  - the average weekly trading volume of our common stock in the public market
    during the four calendar weeks immediately before such sale.
 
Sales under Rule 144 are also subject to certain requirements as to the manner
of sale, notice and availability of current public information about us.
 
Under Rule 144(k), a person who has not been one of our "affiliates" at any time
during the 90 days before a sale, and who has beneficially owned shares proposed
to be sold for at least two years, is entitled to sell such shares without
regard to the volume limitations, manner of sale provisions or notice
requirements.
 
Subject to certain limitations on the aggregate offering price of a transaction
and other conditions, Rule 701 of the Securities Act, as currently in effect,
permits the resale of securities originally purchased from us by our employees,
directors, officers, consultants or advisers prior to the closing of this
offering in connection with a compensatory stock or option plan or written
agreement, by persons who are not our "affiliates" subject only to the
manner-of-sale provisions of Rule 144 and by our affiliates under Rule 144
without compliance with its minimum holding period requirement.
 
All of our officers, directors and stockholders have agreed that they will not,
without the prior written consent of CIBC Oppenheimer Corp., which consent may
be withheld in its sole discretion, and subject to certain limited exceptions,
directly or indirectly, sell, offer, contract or grant any option to sell, make
any short sale, pledge, transfer, establish an open "put equivalent position"
within the meaning of Rule 16a-1(h) under the Exchange Act, or otherwise dispose
of any shares of common stock, options or warrants to acquire common stock, or
securities exchangeable or exercisable for or convertible into common stock
currently owned either of record or beneficially by them or announce the
intention to do any of the acts listed above, for a period beginning on the date
of this prospectus and continuing to the date which is 180 days after the date
of this prospectus. CIBC Oppenheimer Corp. may, in its sole discretion and any
time without notice, release all or any portion of the securities subject to
these lock-up agreements. In addition, we have agreed that, for a period of 180
days after the date of this prospectus, we will not, without the consent of CIBC
Oppenheimer Corp., issue, offer, sell or grant options to purchase or otherwise
dispose of any equity securities or securities convertible into or exchangeable
for equity securities except for (i) the issuance of shares of common stock
offered hereby and (ii) the grant of options to
 
                                       61
<PAGE>   66
 
purchase shares of common stock under the 1999 Stock Incentive Plan and shares
of common stock issued upon the exercise of outstanding options on or after the
date of this prospectus. See "Underwriting."
 
There are no restrictions on resale with respect to any of our securities, other
than restrictions imposed by lock-up agreements and applicable securities laws.
As a result of the lock-up agreements described above and the provisions of Rule
144 and 701, the restricted shares will be available for sale in the public
market immediately upon expiration of the 180 day lock-up period, subject to the
volume limitations and other conditions of Rule 144. Sales of our common stock
by these stockholders could have a material adverse effect on the trading price
of our common stock.
 
We have granted options to purchase up to 1,006,320 shares of common stock under
the 1997 Equity Incentive Plan. Concurrently with the sale of the shares offered
hereby, we will grant options to purchase an additional           shares of
common stock pursuant to the 1999 Equity Incentive Plan. An additional
          shares currently are reserved for issuance under the 1999 Stock
Incentive Plan. No options are outstanding under the 1999 Stock Incentive Plan.
Immediately after this offering, we intend to register the sale of the shares of
common stock issuable under the 1997 Equity Incentive Plan and 1999 Stock
Incentive Plan under the Securities Act. See "Management -- Stock Options."
Accordingly, as awards under the stock option plans vest, shares issued upon
exercise of these stock options will be freely tradable and available for sale
in the open market, immediately after the 180-day lock-up agreements expire,
except such shares as may be acquired by one of our "affiliates."

                                  UNDERWRITING
 
CRL Network Services, Inc. and the selling stockholder have entered into an
underwriting agreement with the underwriters named below. CIBC Oppenheimer Corp.
and Lehman Brothers Inc. are acting as representatives of the underwriters.
 
The underwriting agreement provides for the purchase of a specific number of
shares of common stock by each of the underwriters. The underwriters'
obligations are several, which means that each underwriter is required to
purchase a specified number of shares, but is not responsible for the commitment
of any other underwriter to purchase shares. Subject to the terms and conditions
of the underwriting agreement, each underwriter has severally agreed to purchase
the number of shares of common stock set forth opposite its name below:

CIBC Oppenheimer Corp. .....................................

</TABLE>
 
This is a firm commitment underwriting. This means that the underwriters have
agreed to purchase all of the shares offered by this prospectus (other than
those covered by the over-allotment option described below) if any are
purchased.
 
The representatives have advised CRL and the selling stockholder that the
underwriters propose to offer the shares directly to the public at the public
offering price that appears on the cover page of this prospectus. In addition,
the representatives may offer some of the shares to certain securities dealers
at such price less a concession of $     per share. The underwriter may also
allow, and such dealers may reallow, a concession not in excess of $     per
share to certain other dealers. After the shares are released for sale to the
public, the representatives may change the offering price and other selling
terms at various times.
 
CRL and the selling stockholder have granted the underwriters an over-allotment
option. This option, which is exercisable for up to 30 days after the date of
this prospectus, permits the underwriters to purchase a maximum of
additional shares from the selling stockholder or, at the selling stockholder's
option, CRL, to cover over-allotments. If the underwriters exercise all or part
of this option, they will purchase shares covered by the option at the initial
public offering price that appears on the cover page of this prospectus, less
the underwriting discount. If this option is exercised in full from the selling
stockholder, the total price to public will be $          , the total proceeds
to CRL will be $          and the total proceeds to the selling stockholder will
be $       . If this option is exercised in full from CRL, the total proceeds to
CRL will be $          and the total proceeds to the selling stockholder will be
$          . The underwriters have severally agreed that, to the extent the
over-allotment option is exercised, they will each purchase a number of
additional shares proportionate to the underwriter's initial amount reflected in
the foregoing table.
 
The following table provides information regarding the amount of the discount to
be paid to the underwriters by CRL and the selling stockholder.

CRL and the selling stockholder estimate that their portions of the total
expenses of the offering, excluding the underwriting discount, will be
approximately $          and $          , respectively.
 
CRL and the selling stockholder have agreed to indemnify the underwriters
against certain liabilities, including liabilities under the Securities Act of
1933.
 
CRL, its officers and directors and other stockholders have agreed to a 180-day
"lock up" with respect to                     shares of common stock and certain
other CRL securities that they beneficially own, including securities that are
convertible into shares of common stock and securities that are exchangeable or
exercisable for shares of common stock. This means that, for a period of 180
days following the date of this prospectus, CRL and such persons may not offer,
sell, pledge or otherwise dispose of these CRL securities without the prior
written consent of CIBC Oppenheimer Corp.
 
The representatives have informed CRL that they do not expect discretionary
sales by the underwriters to exceed five percent of the shares offered by this
prospectus.
 
There is no established trading market for the shares. The offering price for
the shares has been determined by CRL and the representatives, based on the
following factors:
 
  - negotiations among CRL and the representatives
 
  - prevailing market and economic conditions
 
  - certain financial information of CRL
 
  - the history of, and the prospects for CRL
 
  - CRL and the industry in which it competes
 
  - an assessment of CRL management, its past and present operations, the
    prospects for, and timing of, future revenues of CRL
 
  - the present stage of CRL's development and the above factors in relation to
    market values and various valuation measures of other companies engaged in
    activities similar to those of CRL's
 
The initial public offering price set forth on the cover page of this prospectus
should not, however, be considered an indication of the actual value of the
common stock. Such price is subject to change as a result of market conditions
and other factors. There can be no assurance that an active trading market will
develop for the common stock or that the common stock will trade in the public
market subsequent to this offering at or above the initial offering price.
 
The underwriters may engage in the following activities in accordance with the
rules of the Securities and Exchange Commission:
 
  - Stabilizing transactions -- The representatives may make bids or purchases
    for the purpose of pegging, fixing or maintaining the price of the shares,
    so long as stabilizing bids do not exceed a specified maximum.
 
  - Over-allotments and syndicate covering transactions -- The underwriters may
    create a short position in the shares by selling more shares than are set
    forth on the cover page of this prospectus. If a short position is created
    in connection with the offering, the representatives may engage in syndicate
    covering transactions by purchasing shares in the open market. The
    representatives may also elect to reduce any short position by exercising
    all or part of the over-allotment option.
 
  - Penalty bids -- If the representatives purchase shares in the open market in
    a stabilizing transaction or syndicate covering transaction, they may
    reclaim a selling concession from the underwriters and selling group members
    who sold those shares as part of this offering.
 
Stabilization and syndicate covering transactions may cause the price of the
shares to be higher than it would be in the absence of such transactions. The
imposition of a penalty bid might also have an effect on the price of the shares
if it discourages resales of the shares.

the effect that the transactions described above may have on the price of the
shares. These transactions may occur on the Nasdaq National Market or otherwise.
If such transactions are commenced, they may be discontinued without notice at
any time.

                          INDEPENDENT AUDITORS' REPORT
 
"To the Stockholders and Board of Directors of
CRL Network Services, Inc.:
 
We have audited the accompanying consolidated balance sheets of CRL Network
Services, Inc. and subsidiary as of December 31, 1997 and 1998, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended December 31, 1998. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, such consolidated financial statements present fairly, in all
material respects, the financial position of CRL Network Services, Inc. and
subsidiary as of December 31, 1997 and 1998, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1998, in conformity with generally accepted accounting principles.
 
San Francisco, California
March 18, 1999 (March   ,1999 as to the last paragraph in note 12)"
 
The consolidated financial statements included herein reflect the
reincorporation of the Company in the state of Delaware and the associated
exchange of one share of common stock of the Company for every three shares of
common stock of the Company's California predecessor entity as described in Note
12 to the consolidated financial statements. The above report is in the form
which will be signed by Deloitte & Touche LLP upon the effectiveness of such
event, which is described in Note 12 of Notes to the Financial Statements and
assuming that from March 18, 1999 to the effective date of such events, no other
events shall have occurred, other than those described in Note 12 of Notes to
the Financial Statements, that would affect the accompanying consolidated
financial statements and notes thereto.

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES
 
THE COMPANY -- CRL Network Services, Inc. and subsidiary ("CRL" or the
"Company") was incorporated in the state of California in 1993. CRL is a Tier 1
Internet service provider focused on offering tailored Internet and network
management solutions to small and medium-sized businesses across the United
States through a national fiber-optic data network.
 
PRINCIPLES OF CONSOLIDATION -- The consolidated financial statements include the
accounts of CRL and its wholly owned subsidiary. All intercompany balances and
transactions have been eliminated.
 
USE OF ESTIMATES -- The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
CASH AND EQUIVALENTS -- The Company considers all highly liquid monetary
instruments with an original maturity of three months or less from the date of
purchase to be cash equivalents.
 
PROPERTY AND EQUIPMENT -- Property and equipment are recorded at cost and
depreciated using the straight-line method over their useful lives. Equipment
held under capital leases is amortized on the straight-line method over the
shorter of the lease term or the estimated useful life of the asset. Estimated
useful lives are as follows:

</TABLE>
 
REVENUE RECOGNITION -- Revenues from colocation and internet connectivity are
recognized when the services are performed. Revenues from systems integration
and services are recognized when hardware is shipped and the installation and
integration is complete. Deferred revenue represents amounts billed in advance
of services not yet provided.
 
ADVERTISING EXPENSES -- All costs related to marketing and advertising the
Company's products are expensed in the periods incurred. Advertising expenses
were $80, $27 and $60 for 1996, 1997 and 1998, respectively.
 
INCOME TAXES -- The Company accounts for income taxes using the asset and
liability method in accordance with Statement of Financial Accounting Standards
No. 109 ("SFAS 109"). Under this method, deferred tax liabilities and assets are
determined based on the difference between the financial statement and tax bases
of assets and liabilities using enacted tax rates in effect for the year in
which the differences are expected to reverse.
 
STOCK-BASED COMPENSATION -- The Company accounts for stock-based awards to
employees using the intrinsic value method in accordance with APB No. 25,
Accounting for Stock Issued to Employees. Accordingly, no accounting recognition
is given to stock options granted at fair market value until they are exercised.
Compensation expense related to employee stock options is recorded if, on the
date of grant, the fair value of the underlying stock exceeds the exercise
price.
 
CONCENTRATION OF CREDIT RISK -- Financial instruments that potentially subject
the Company to concentration of credit risk consist of trade receivables. The
Company's receivables are subject to geographic concentrations of credit risk.
This risk is mitigated by the Company's credit evaluation process

NOTE 1 -- SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
and the reasonably short collection terms. The Company does not require
collateral or other security to support accounts receivable and maintains
reserves for potential credit losses.
 
FINANCIAL INSTRUMENTS -- The Company's financial instruments include cash and
equivalents, accounts receivable and debt. At December 31, 1997 and 1998, the
carrying amounts of these instruments approximates their fair values.
 
IMPAIRMENT OF LONG-LIVED ASSETS AND LONG-LIVED ASSETS TO BE DISPOSED OF -- The
Company evaluates its long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of such assets or
intangibles may not be recoverable. Recoverability of assets to be held and used
is measured by a comparison of the carrying amount of an asset to future
undiscounted net cash flows expected to be generated by the asset. If such
assets are considered to be impaired, the impairment to be recognized is
measured by the amount by which the carrying amount of the assets exceeds the
fair value of the assets. Assets to be disposed of are reported at the lower of
the carrying amount or fair value less costs to sell.
 
NET INCOME (LOSS) PER SHARE -- Basic income (loss) per share excludes dilution
and is computed by dividing net income (loss) by the weighted-average number of
common shares outstanding for the period. Diluted income (loss) per share
reflects the potential dilution that could occur if options to issue common
stock were exercised.
 
STOCKHOLDERS' EQUITY -- In August 1997, the Company's Board of Directors
authorized a 2,318 for 1 stock split. The stock split was effective and
distributed to the sole stockholder of record on August 8, 1997. Additionally,
in December 1998, the Company's Board of Directors authorized a 20 for 1 stock
split. The stock split was effective and distributed to the sole stockholder of
record on December 2, 1998. All share information in the financial statements
has been restated to give retroactive recognition to the stock splits.
 
In December 1998, the Board also authorized an increase in the number of
authorized shares of common stock to 200,000,000 (not giving effect to the
reincorporation).
 
COMPREHENSIVE INCOME -- There are no differences between comprehensive income
and net income as reported in the Company's statements of operations.
 
RECLASSIFICATIONS -- Certain prior years amounts have been reclassified to
conform to the current year presentation. Such reclassifications had no effect
on stockholders' equity or net income (loss).
 
RECENTLY ISSUED ACCOUNTING STANDARDS -- In March 1998, the Accounting Standards
Executive Committee of the American Institute of Certified Public Accountants
issued SOP 98-1, Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use. SOP 98-1 provides guidance for an enterprise on
accounting for the costs of computer software developed or obtained for internal
use. SOP 98-1 is effective for the Company in fiscal 1999. The Company
anticipates that accounting for transactions under SOP 98-1 will not have a
material impact on the Company's financial position or results of operations.
 
In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities, which defines derivatives, requires that all
derivatives be carried at fair value, and provides for hedge accounting when
certain conditions are met. SFAS No. 133 is effective for the Company in fiscal
2000. The Company does not believe adoption of this statement will have a
material impact on the Company's financial position or results of operations.

NOTE 2 -- MERGER
 
On December 21, 1998, the merger of Integral Networking Corporation ("Integral")
was completed. Under the terms of the Integral merger, which was accounted for
as a pooling-of-interests, 434,833 shares of CRL common stock were exchanged for
all of the outstanding Integral common shares at an exchange ratio of 5.80
shares of CRL for each share of Integral.
 
The financial information for all prior periods presented has been restated to
present the combined financial condition and results of operations for both
companies as if the merger had been in effect for all periods presented.
 
The following table presents a reconciliation of net sales and net income (loss)
previously reported by the company to those presented in the accompanying

NOTE 3 -- ALLOWANCES FOR DOUBTFUL ACCOUNTS
 
Allowances for doubtful accounts are estimated and established based on
historical experience and specific circumstances of each customer. Additions to
the allowance are charged to general and administrative expenses. Accounts
receivable are written off against the allowance for doubtful accounts when an
account is deemed uncollectible. Recoveries on accounts receivable previously
charged off as uncollectible are credited to the allowance for doubtful
accounts. Changes in the allowance for doubtful accounts were as follows:

No valuation allowance has been established for the deferred tax asset.
Management believes that the Company will be able to realize the tax benefit of
the deferred tax assets based on expected future taxable income and the future
reversal of taxable temporary differences.

NOTE 7 -- STOCK OPTION AND OTHER EMPLOYEE BENEFIT PLANS
 
401(K) PLAN -- In September 1997, the Company implemented a 401(k) plan covering
all employees who have met certain eligibility requirements. Under the 401(k)
plan, employees may elect to contribute up to 15% of their eligible compensation
(to a maximum of $10) to the 401(k) plan, subject to certain limitations. The
Company may make matching contributions at its discretion. As of December 31,
1997 and 1998, the Company had not made any contributions to the 401(k) plan.
 
STOCK BASED COMPENSATION PLAN -- In August 1997, the Board of Directors approved

ADDITIONAL STOCK PLAN INFORMATION -- As discussed in Note 1, the Company
accounts for its stock-based awards to employees using the intrinsic value
method in accordance with APB No. 25, Accounting for Stock Issued to Employees,
and its related interpretations.
 
SFAS No. 123, Accounting for Stock-Based Compensation, requires the disclosure
of pro forma net income (loss) and earnings (loss) per share had the Company
adopted the fair value method since the Company's inception. Under SFAS No. 123,
the fair value of stock-based awards to employees is calculated through the use
of option pricing models, even though such models were developed to estimate

TELECOMMUNICATIONS AND PEERING ARRANGEMENTS -- The Company enters into
telecommunications agreements with telephone companies who provide local access
for dial-up customers to the Company's Internet backbone. The terms of the
service agreements vary from one to two years and provide the Company with
preferred rates. If the Company prematurely cancels one of these service
contracts, the service provider, at their discretion, can charge the difference
between their regular rates and the preferred rate over the term of the service.
In the past, no service provider has exercised this option. Management believes
that potential additional charges, if any, from early cancellation of vendor
service contracts would not have a material effect on the financial statements.

NOTE 11 -- COMMITMENTS AND CONTINGENCIES (CONTINUED)
The Company is party to numerous peering arrangements with other internet
providers to allow for the exchange of internet traffic. The Company does not
record any revenue or expense associated with these non-cash transactions as
such transactions do not represent the culmination of the earnings process and
the fair value of such transactions are not reasonably determinable.
 
LEGAL MATTERS -- The Company is involved in various claims and legal actions
arising out of the normal course of business. Management does not expect that
the outcome of these cases will have a material effect on the Company's
financial position, results of operations or cash flow.
 
QWEST DISPUTE -- The Company is currently in a dispute with Qwest Communications
Corporation involving certain fiber cable they own connecting several cities.
Qwest agreed to lease fiber that was to be installed and available to the
Company by certain specified dates. Qwest did not complete installation as
agreed. The Company believes that Qwest is obligated to provide free service as
a result of the installation delay. As of December 31, 1998, Qwest has demanded
payment of $136 which includes a credit of $108 for free service. The Company
disputes the installation dates and application of service order terms and is
seeking arbitration of the dispute. As of December 31, 1998, no accrual had been
made for the Qwest dispute.
 
NOTE 12 -- SUBSEQUENT EVENTS

compensation expense of $98. The compensation expense will be recorded over the
five-year vesting period of the options.
 
On March 11, 1999, the Company terminated its relationship with FBN effective
April 30, 1999 (see Note 9).

shares of common stock of the Company's California predecessor. Such
reincorporation and stock exchange will become effective prior to the effective
date of the initial public offering contemplated by the Company. All share and
per share amounts in these financial statements have been adjusted to give
effect to the reincorporation and one for three stock exchange.
 
On March   , 1999 the Company completed the reincorporation of the Company in
the State of Delaware and the associated exchange of one share of common stock
of the Company for every 3 shares of common stock of the Company's California

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
Section 145 of the General Corporation Law of the State of Delaware provides for
the indemnification of officers and directors under certain circumstances
against expenses incurred in successfully defending against a claim and
authorizes Delaware corporations to indemnify their officers and directors under
certain circumstances against expenses and liabilities incurred in legal
proceedings involving such persons because of their being or having been an
officer or director. Article VIII of the Registrant's Certificate of
Incorporation and the Registrant's Bylaws provide that all persons who the
Registrant is empowered to indemnify pursuant to the provisions of Section 145
of the Delaware General Corporation Law (or any similar provision or provisions
of applicable law at the time in effect), shall be indemnified by the Registrant
to the full extent permitted thereby. The foregoing right of indemnification
shall not be deemed to be exclusive of any other rights to which those seeking
indemnification may be entitled under any by-law, agreement, vote of
stockholders or disinterested directors, or otherwise.
 
Section 102(b) of the Delaware General Corporation Law permits a corporation, by
so providing in its certificate of incorporation, to eliminate or limit
director's liability to the corporation and its stockholders for monetary
damages arising out of certain alleged breaches of their fiduciary duty. Section
102(b)(7) provides that no such limitation of liability may affect a director's
liability with respect to any of the following: (i) breaches of the director's
duty of loyalty to the corporation or its stockholders; (ii) acts or omissions
not made in good faith or which involve intentional misconduct of knowing
violations of law; (iii) liability for dividends paid or stock repurchased or
redeemed in violation of the Delaware General Corporation law; or (iv) any
transaction from which the director derived an improper personal benefit.
Section 102(b)(7) does not authorize any limitation on the ability of the
corporation or its stockholders to obtain injunction relief, specific
performance or other equitable relief against directors.
 
Reference is made to the Underwriting Agreement, the proposed form of which is
filed as Exhibit 1.1, pursuant to which the underwriters agree to indemnify the
directors and certain officers of the Registrant and certain other persons in
certain circumstances.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
Since January 1, 1996, the Registrant's predecessor company has issued and sold
the following securities:
 
On December 21, 1998, the Registrant issued and sold an aggregate of 434,832
shares of common stock (giving effect to the Registrant's reincorporation in
Delaware and the associated exchange of one share of common stock of CRL for
every three shares of common stock of CRL's California predecessor) to three
former shareholders of Integral Network Corporation in connection with the
merger of Integral Network Corporation with a wholly-owned subsidiary of the
Registrant.
 
The issuance and sale of the above securities were exempt from registration
under the Securities Act in reliance upon Section 4(2) of the Securities Act or
Regulation D promulgated thereunder. The recipients of securities in each such
transaction represented their intentions to acquire the securities for
investment only and now with a view to or for sale in connection with any
distribution thereof, and appropriate legends were affixed to the share
certificates issued in such transactions. All recipients had adequate access to
information about the Registrant.
 
Prior to the closing of this offering, CRL Network Services, Inc., a California
corporation ("CRL California"), will merge with and into its wholly-owned
subsidiary, CRL Network Services, Inc., a Delaware corporation ("CRL Delaware").
In connection with the merger, CRL Delaware will issue shares of common stock to
the holders of common stock of CRL California, such that the holders of common
stock of CRL California will receive a proportionate interest in CRL Delaware
common stock, without giving effect to the offering. The issuance of the
securities and such reincorporation will be exempt from the registration
requirements of the Securities Act of 1933, as amended, due to the exemptions
from registration provided by Sections 3(a)(9) and 4(2) thereof.

ITEM 17. UNDERTAKINGS
 
The Registrant hereby undertakes to the underwriters at the closing specified in
the underwriting agreement to provide certificates in such denominations and
registered in such names as required by the underwriters to permit prompt
delivery to each purchaser.
 
Insofar as indemnification for liabilities arising under the Securities Act of
1933, as amended (the "Securities Act") may be permitted to directors, officers
and controlling persons of the Registrant pursuant to the Delaware General
Corporation Law, the Registrant's Amended Certificate of Incorporation, the
Registrant's Bylaws, or otherwise, the Registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act, and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
The undersigned Registrant hereby undertakes that:
 
     (i) For purposes of determining any liability under the Securities Act, the
     information omitted from the form of prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in a form
     of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the Act is part of this Registration Statement as of the time
     it was declared effective.
 
     (ii) For the purpose of determining any liability under the Securities Act
     of 1933, each post-effective amendment that contains a form of prospectus
     shall be deemed to be a new registration statement for the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.

On behalf of the Several Underwriters named on Schedule I attached hereto.

Ladies and Gentlemen:

               CRL Network Services, Inc., a Delaware corporation (the
"Company"), and James Couch, the Chief Executive Officer and a Shareholder of
the Company (the "Selling Stockholder"), proposes to sell to you and the other
underwriters named on Schedule I to this Agreement (the "Underwriters"), for
whom you are acting as Representatives, an aggregate of ____________ shares (the
"Firm Shares") of the Company's Common Stock, (the "Common Stock"). The Company
proposes to issue and sell ____ shares of its authorized and unissued Common
Stock (the "Company Shares") and the Selling Stockholder proposes to sell in
aggregate of _____ shares of the Company's authorized and outstanding Common
Stock (the "Selling Stockholder Shares") to the Underwriters. In addition, the
Selling Stockholder and the Company propose to grant, jointly and severally, to
the several Underwriters an option to purchase severally and not jointly, up to
an additional ___________ shares (the "Option Shares") of Common Stock from them
for the purpose of covering over-allotments in connection with the sale of the
Firm Shares. The Firm Shares and the Option Shares are together called the
"Shares."

               1. Sale and Purchase of the Shares.

               On the basis of the representations, warranties and agreements
contained in, and subject to the terms and conditions of, this Agreement:

                      (a) The Company agrees to sell to each of the

the Firm Shares Closing Date or at least two business days before the Option
Shares Closing Date (as defined below), as the case may be, setting forth the

Underwriters and payment of the purchase price by certified or official bank
check or checks payable in next day funds to the Selling Stockholder and/or the

above at the time and on the date or dates (which may be the same date as, but
in no event shall be earlier than, the Firm Shares Closing Date) specified in
the notice referred to in Section 1(c) (such time and date of delivery and
payment are called the "Option Shares Closing Date"). The Firm Shares Closing
Date and the Option Shares Closing Date are called, individually, a "Closing
Date" and, together, the "Closing Dates."

               Certificates evidencing the Shares shall be registered in such
names and shall be in such denominations as the Representatives shall request at
least two full business days before the Firm Shares Closing Date or, in the case
of Option Shares, on the day of notice of exercise of the option as described in
Section l(c) and shall be made available to the Representatives for checking and

business day before the Firm Shares Closing Date (or the Option Shares Closing
Date in the case of the Option Shares).

               3. Registration Statement and Prospectus; Public Offering. The
Company has prepared in conformity with the requirements of the Securities Act
of 1933, as amended (the "Securities Act"), and the published rules and
regulations thereunder (the "Rules") adopted by the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-1 (No.
333-_____), including a preliminary prospectus relating to the Shares, and has
filed with the Commission the Registration Statement (as hereinafter defined)
and such amendments thereof as may have been required to the date of this
Agreement. Copies of such Registration Statement (including all amendments
thereto) to and of the related preliminary prospectus have heretofore been
delivered by the Company to you.

               The Company understands that the Underwriters propose to make a
public offering of the Shares, as set forth in and pursuant to the Prospectus,
as soon after the Effective Date and the date of this Agreement as the
Representatives deem advisable. The Company hereby confirms that the
Underwriters and dealers have been authorized to distribute or cause to be
distributed each preliminary prospectus and are authorized to distribute the
Prospectus (as from time to time amended or supplemented if the Company
furnishes amendments or supplements thereto to the Underwriters).

               4. Representations and Warranties of the Company and the Selling
Stockholder. The Company and the Selling Stockholder hereby, jointly and
severally, represent, warrant and covenant to each Underwriter as follows:

                      (a) If the registration statement relating to the Shares
has been declared effective under the Securities Act by the Commission, the
Company will prepare and promptly file with the Commission the information
omitted from the registration statement pursuant to Rule 430A(a) or, if the
Representatives, on behalf of the several Underwriters, shall agree to the
utilization of Rule 434 of the Rules, the information required to be included in
any term sheet filed pursuant to Rule 434(b) or (c), as applicable, of the Rules
pursuant to subparagraph (1), (4) or (7) of Rule 424(b) of the Rules or as part
of a post-effective amendment to the registration statement (including a final
form of prospectus). If the registration statement relating to the Shares has
not been declared effective under the Securities Act by the


                                       3


<PAGE>   4
Commission, the Company will prepare and promptly file an amendment to the
registration statement, including a final form of prospectus, or, if the
Representatives, on behalf of the several Underwriters, shall agree to the
utilization of Rule 434 of the Rules, the information required to be included in
any term sheet filed pursuant to Rule 434(b) or (c), as applicable, of the
Rules. The term "Registration Statement" as used in this Agreement shall mean
such registration statement, including consolidated financial statements,
schedules and exhibits, in the form in which it became or becomes, as the case
may be, effective (including, if the Company omitted information from the
registration statement pursuant to Rule 430A(a) or files a term sheet pursuant
to Rule 434 of the Rules, the information deemed to be a part of the
registration statement at the time it became effective pursuant to Rule 430A(b)
or Rule 434(d) of the Rules) and, in the event of any amendment thereto or the
filing of any abbreviated registration statement pursuant to Rule 462(b) of the
Rules relating thereto after the effective date of such registration statement
(the "Effective Date"), shall also mean (from and after the effectiveness of
such amendment or the filing of such abbreviated registration statement) such
registration statement as so amended, together with any such abbreviated
registration statement. The term "Prospectus" as used in this Agreement shall
mean the prospectus relating to the Shares as included in such Registration
Statement at the time it becomes effective (including, if the Company omitted
information from the Registration Statement pursuant to Rule 430A(a) of the
Rules, the information deemed to be a part of the Registration Statement at the
time it became effective pursuant to Rule 430A(b) of the Rules); provided,
however, that if in reliance on Rule 434 of the Rules and with the consent of
the Representatives, on behalf of the several Underwriters, the Company shall
have provided to the Underwriters a term sheet pursuant to Rule 434(b) or (c),
as applicable, prior to the time that a confirmation is sent or given for
purposes of Section 2(10)(a) of the Securities Act, the term "Prospectus" shall
mean the "prospectus subject to completion" (as defined in Rule 434(g) of the
Rules) last provided to the Underwriters by the Company and circulated by the
Underwriters to all prospective purchasers of the Shares (including the
information deemed to be a part of the Registration Statement at the time it
became effective pursuant to Rule 434(d) of the Rules). Notwithstanding the
foregoing, if any revised prospectus shall be provided to the Underwriters by
the Company for use in connection with the offering of the Shares that differs
from the prospectus referred to in the immediately preceding sentence (whether
or not such revised prospectus is required to be filed with the Commission
pursuant to Rule 424(b) of the Rules), the term "Prospectus" shall refer to such
revised prospectus from and after the time it is first provided to the
Underwriters for such use. If in reliance on Rule 434 of the Rules and with the
consent of the Representatives, on behalf of the several Underwriters, the
Company shall have provided to the Underwriters a term sheet pursuant to Rule
434(b) or (c), as applicable, prior to the time that a confirmation is sent or
given for purposes of Section 2(10)(a) of the Securities Act, the Prospectus and
the term sheet, together, will not be materially different from the prospectus
in the Registration Statement.

        On the Effective Date the Registration Statement complied, and on the
date of the Prospectus, on the date any post-effective amendment to the
Registration Statement shall become effective, on the date any supplement or
amendment to the Prospectus is filed with the Commission and on each Closing
Date, the Registration Statement and the Prospectus (and any amendment thereof
or supplement thereto) will comply, in all material respects, with the
applicable provisions of the Securities Act and the Rules and the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), and the rules and
regulations of the Commission thereunder; the Registration Statement did not, as
of the Effective Date, contain any untrue


                                       4


<PAGE>   5
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein not
misleading; and on the other dates referred to above neither the Registration
Statement nor the Prospectus, nor any amendment thereof or supplement thereto,
will contain any untrue statement of a material fact or will omit to state any
material fact required to be stated therein or necessary in order to make the
statements therein not misleading. When any related preliminary prospectus was
first filed with the Commission (whether filed as part of the Registration
Statement or any amendment thereto or pursuant to Rule 424(a) of the Rules) and
when any amendment thereof or supplement thereto was first filed with the
Commission, such preliminary prospectus as amended or supplemented complied in
all material respects with the applicable provisions of the Securities Act and
the Rules and did not contain any untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary in order to
make the statements therein not misleading. Notwithstanding the foregoing, the
Company and the Selling Stockholder make no representation or warranty as to the
paragraph with respect to stabilization on the inside front cover page of the
Prospectus and the statements contained under the caption "Underwriting" in the
Prospectus. The Company and the Selling Stockholder acknowledge that the
statements referred to in the previous sentence constitute the only information
furnished in writing by the Representatives on behalf of the several
Underwriters specifically for inclusion in the Registration Statement, any
preliminary prospectus or the Prospectus.

                      (b) All contracts and other documents required to be filed
as exhibits to the Registration Statement have been filed with the Commission as
exhibits to the Registration Statement.

                      (c) The consolidated financial statements of the Company
and its subsidiaries (including all notes and schedules thereto) included in the
Registration Statement and Prospectus present fairly the financial position, the
results of operations and cash flows and the stockholders' equity and the other
information purported to be shown therein of the Company and its subsidiaries at
the respective dates and for the respective periods to which they apply; and
such financial statements have been prepared in conformity with generally
accepted accounting principles, consistently applied throughout the periods
involved, and all adjustments necessary for a fair presentation of the results
for such periods have been made. The selected and summary consolidated financial
and operational data included in the Registration Statement present fairly the
information shown therein and have been compiled on a basis consistent with the
audited financial statements. No other financial statements or schedules are
required to be included in the Registration Statement.

                      (d) Deloitte & Touche LLP whose reports are filed with the
Commission as a part of the Registration Statement, are and, during the periods
covered by their reports, were independent public accountants as required by the
Securities Act and the Rules.

                      (e) The Company has been duly incorporated and is validly
existing as corporation in good standing under the laws of the State of Delaware
and the Company's subsidiary has been duly incorporated and is validly existing
as a corporation in good standing under the laws of the State of California. The
Company has no subsidiary or subsidiaries and does not control, directly or
indirectly, any corporation, partnership, joint venture, association or other
business organization other than the subsidiaries listed on Exhibit 21 to the
Registration


                                       5


<PAGE>   6
Statement. Each of the Company and its subsidiary are duly qualified and in good
standing as foreign corporations in each jurisdiction in which the character or
location of its assets or properties (owned, leased or licensed) or the nature
of its businesses makes such qualification necessary except for such
jurisdictions where the failure to so qualify would not have a material adverse
effect on the assets or properties, business, results of operations or financial
condition of the Company or its subsidiary. Except as disclosed in the
Registration Statement and the Prospectus, neither the Company nor its
subsidiary own, lease or license any asset or property or conduct any businesses
outside the United States of America. Each of the Company and its subsidiary has
all requisite corporate power and authority, and all necessary authorizations,
approvals, consents, orders, licenses, certificates and permits of and from all
governmental or regulatory bodies or any other person or entity, to own, lease
and license its assets and properties and conduct its businesses as now being
conducted and as described in the Registration Statement and the Prospectus
except for such authorizations, approvals, consents, orders, material licenses,
certificates and permits the failure to so obtain would not have a material
adverse effect upon the assets or properties, business, results of operations,
prospects or condition (financial or otherwise) of the Company or its subsidiary
and each of the Company and its subsidiary has all such corporate power and
authority, and such authorizations, approvals, consents, orders, licenses,
certificates and permits to enter into, deliver and perform this Agreement and
to issue and sell the Shares (except as may be required under the Securities Act
and state and foreign Blue Sky laws).

                      (f) Each of the Company and its subsidiary owns or
possesses adequate rights to use all patents, patent rights, inventions, trade
secrets, know-how, trademarks, service marks, trade names and copyrights which
are necessary to conduct its businesses as described in the Registration
Statement and Prospectus; the expiration of any patents, patent rights, trade
secrets, trademarks, service marks, trade names or copyrights would not have a
material adverse effect on the condition (financial or otherwise), earnings,
operations, business or business prospects of the Company or its subsidiary.
Neither the Company, its subsidiary nor the Selling Stockholder have received
any notice of, and neither the Company, its subsidiary nor the Selling
Stockholder has any knowledge of, any infringement of or conflict with asserted
rights of the Company or its subsidiary by others with respect to any patent,
patent rights, inventions, trade secrets, know-how, trademarks, service marks,
trade names or copyrights; and each of the Company and its subsidiary has not
received any notice of, and neither the Company, its subsidiary nor the Selling
Stockholder has any knowledge of, any infringement of or conflict with asserted
rights of others with respect to any patent, patent rights, inventions, trade
secrets, know-how, trademarks, service marks, trade names or copyrights which,
singly or in the aggregate, if the subject of an unfavorable decision, ruling or
finding, might have a material adverse effect on the condition (financial or
otherwise), earnings, operations, business or business prospects of the Company
or its subsidiary.

                      (g) Each of the Company and its subsidiary has good title
to each of the items of personal property which are reflected in the financial
statements referred to in Section 4(c) or are referred to in the Registration
Statement and the Prospectus as being owned by it and valid and enforceable
leasehold interests in each of the items of real and personal property which are
referred to in the Registration Statement and the Prospectus as being leased by
it, in each case free and clear of all liens, encumbrances, claims, security
interests and defects, other than those described in the Registration Statement
and the Prospectus and those which do


                                       6


<PAGE>   7
not and will not have a material adverse effect upon the assets or properties,
business, results of operations or financial condition of the Company or its
subsidiary.

                      (h) There is not any pending or, to the best of the
Company's and the Selling Stockholder or its subsidiaries' knowledge, threatened
action, suit, claim or proceeding against the Company, any of its respective
officers or any of its respective properties, assets or rights before any court,
government or governmental agency or body, domestic or foreign, having
jurisdiction over the Company or its subsidiary, or over its respective officers
or properties or otherwise which (i) might result in any material adverse change
in the condition (financial or otherwise), earnings, operations, business or
business prospects of the Company or its subsidiary or might materially and
adversely affect its properties, assets or rights, (ii) might prevent
consummation of the transactions contemplated hereby or (iii) is required to be
disclosed in the Registration Statement or Prospectus and is not so disclosed.

                      (i) Subsequent to the respective dates as of which
information is given in the Registration Statement and the Prospectus, except as
described therein, (i) there has not been any material adverse change in the
assets or properties, business, results of operations, prospects or condition
(financial or otherwise), of the Company or its subsidiary, whether or not
arising from transactions in the ordinary course of business; (ii) neither the
Company nor its subsidiary has sustained any material loss or interference with
its assets, businesses or properties (whether owned or leased) from fire,
explosion, earthquake, flood or other calamity, whether or not covered by
insurance, or from any labor dispute or any court or legislative or other
governmental action, order or decree; and (iii) since the date of the latest
balance sheet included in the Registration Statement and the Prospectus, except
as reflected therein, neither the Company nor its subsidiary has (a) issued any
securities or incurred any liability or obligation, direct or contingent, for
borrowed money, except such liabilities or obligations incurred in the ordinary
course of business, (b) entered into any transaction not in the ordinary course
of business or (c) declared or paid any dividend or made any distribution on any
shares of its stock or redeemed, purchased or otherwise acquired or agreed to
redeem, purchase or otherwise acquire any shares of its stock.

                      (j) There is no document or contract required to be
described in the Registration Statement or Prospectus or to be filed as an
exhibit to the Registration Statement which is not described or filed as
required. Each agreement listed in the Exhibits to the Registration Statement is
in full force and effect and is valid and enforceable by and against the Company
or its subsidiaries in accordance with its terms, assuming the due
authorization, execution and delivery thereof by each of the other parties
thereto. Neither the Company nor its subsidiary, nor to the best of the
Company's and its subsidiary's knowledge, any other party is in default in the
observance or performance of any term or obligation to be performed by it under
any such agreement, and no event has occurred which with notice or lapse of time
or both would constitute such a default, in any such case which default or event
would have a material adverse effect on the assets or properties, business,
results of operations, prospects or condition (financial or otherwise) of the
Company or its subsidiary. No default exists, and no event has occurred which
with notice or lapse of time or both would constitute a default, in the due
performance and observance of any term, covenant or condition, by the Company or
its subsidiary of any other agreement or instrument to which the Company or its
subsidiary is a party or by which it or its properties or business may be bound
or affected which default or event would have a material


                                       7


<PAGE>   8
adverse effect on the assets or properties, business, results of operations,
prospects or condition (financial or otherwise) of the Company or its
subsidiary.

                      (k) Neither the Company nor its subsidiary is in violation
of any term or provision of its charter or by-laws or of any franchise, license,
permit, judgment, decree, order, statute, rule or regulation, where the
consequences of such violation would have a material adverse effect on the
assets or properties, business, results of operations, prospects or condition
(financial or otherwise) of the Company or its subsidiary.

                      (l) Neither the execution, delivery and performance of
this Agreement by the Company or its subsidiary nor the consummation of any of
the transactions contemplated hereby (including, without limitation, the
issuance and sale by the Company of the Shares) will give rise to a right to
terminate or accelerate the due date of any payment due under, or conflict with
or result in the breach of any term or provision of, or constitute a default (or
an event which with notice or lapse of time or both would constitute a default)
under, or require any consent or waiver under, or result in the execution or
imposition of any lien, charge or encumbrance upon any properties or assets of
the Company or its subsidiary pursuant to the terms of, any indenture, mortgage,
deed of trust or other agreement or instrument to which the Company or its
subsidiary is a party or by which it or any of its properties or businesses is
bound, or any franchise, license, permit, judgment, decree, order, statute, rule
or regulation applicable to the Company or its subsidiary or violate any
provision of the charter or by-laws of the Company or its subsidiary, except for
such consents or waivers which have already been obtained and are in full force
and effect.

                      (m) The Company has an authorized and outstanding capital
stock as set forth under the caption "Capitalization" in the Prospectus. All of
the outstanding shares of Common Stock have been duly and validly issued and are
fully paid and nonassessable were not issued in violation of or subject to any
preemptive rights and none of them was issued in violation of any preemptive or
other similar right. The Shares, when issued and sold pursuant to this
Agreement, will be duly and validly issued, fully paid and nonassessable, were
not issued in violation of or subject to any preemptive rights and none of them
will be issued in violation of any preemptive or other similar rights. Except as
disclosed in the Registration Statement and the Prospectus, there is no
outstanding option, warrant or other right calling for the issuance of, and
there is no commitment, plan or arrangement to issue, any share of stock of the
Company or any security convertible into, or exercisable or exchangeable for,
such stock. The Common Stock and the Shares conform in all material respects to
all statements in relation thereto contained in the Registration Statement and
the Prospectus. The description of the Company's stock option, stock bonus and
other stock plans or arrangements set forth in the Prospectus accurately and
fairly presents the information required to be shown with respect to such plans,
arrangements, options and rights. All the outstanding shares of capital stock of
the Company's subsidiary have been duly and validly authorized and issued and
are fully paid and nonassessable, and, except as otherwise set forth in the
Prospectus, all outstanding shares of capital stock of the subsidiary are owned
by the Company free and clear of any security interests, claims, liens or
encumbrances.

                      (n) Each officer and director of the Company, the Selling
Stockholder and each beneficial owner of [10,000] or more shares of Common Stock

is declared effective by the Commission (the "Lock-up Period"), offer to sell,
contract to sell, or otherwise sell, dispose of, loan, pledge or grant any
rights with respect to (collectively, a "Disposition") any shares of Common
Stock, any options or warrants to purchase any shares of Common Stock or any
securities convertible into or exchangeable for shares of Common Stock
(collectively, "Securities") now owned or hereafter acquired directly by such
person or with respect to which such person has or hereafter acquires the power
of disposition, otherwise than (i) as a bona fide gift or gifts, provided the
donee or donees thereof agree in writing to be bound by this restriction, (ii)
as a distribution to partners or shareholders of such person, provided that the
distributees thereof agree in writing to be bound by the terms of this
restriction, or (iii) with the prior written consent of the Representatives. The
foregoing restriction has been expressly agreed to preclude the holder of the
Securities from engaging in any hedging or other transaction which is designed
to or reasonably expected to lead to or result in a disposition of Securities
during the Lock-up Period, even if such Securities would be disposed of by
someone other than such holder. Such prohibited hedging or other transactions
would include, without limitation, any short sale (whether or not against the
box) or any purchase, sale or grant of any right (including, without limitation,
any put or call option) with respect to any Securities or with respect to any
security (other than a broad-based market basket or index) that includes,
relates to or derives any significant part of its value from Securities.
Furthermore, such person has also agreed and consented to the entry of stop
transfer instructions with the Company's transfer agent against the transfer of
the Securities held by such person except in compliance with this restriction.

list of all securityholders of the Company and the number and type of securities
held by each securityholder. The Company has provided to counsel for the
Underwriters true, accurate and complete copies of all of the agreements
pursuant to which its officers, directors and shareholders have agreed to such
or similar restrictions (the "Lock-up Agreements") presently in effect or
effected hereby. The Company hereby represents and warrants that it will not
release any of its officers, directors or other shareholders from any Lock-up
Agreements currently existing or hereafter effected without the prior written
consent of the Representatives.

                      (o) All necessary corporate action has been duly and
validly taken by the Company to authorize the execution, delivery and
performance of this Agreement and the issuance and sale of the Shares by the
Company. This Agreement has been duly and validly authorized, executed and
delivered by the Company and will constitute a legal, valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms, except (A) as the enforceability thereof may be limited by bankruptcy,
insolvency, reorganization, moratorium or other similar laws affecting the
enforcement of creditors' rights generally and by general equitable principles
and (B) to the extent that rights to indemnity or contribution under this
Agreement may be limited by Federal and state securities laws or the public
policy underlying such laws.

                      (p) The Company is not involved in any labor dispute nor,
to the knowledge of the Company and the Selling Stockholder, is any such dispute
threatened, which dispute would have a material adverse effect on the assets or
properties, business, results of operations, prospects or condition (financial
or otherwise) of the Company.

cause or result in, or which has constituted or which might reasonably be
expected to constitute, the stabilization or manipulation of the price of the
Common Stock to facilitate the sale or resale of any of the Shares.

                      (s) The Company has filed all Federal, state, local and
foreign tax returns which are required to be filed through the date hereof, or

and all assessments received by it to the extent that the same are material and
have become due.

                      (t) The Shares have been duly authorized for quotation on

               5. The Selling Stockholder represents and warrants to and agrees

               References to the Registration Statement and the Prospectus in
this paragraph (e) are to such documents as amended and supplemented at the date

                      (f) The Representatives shall have received on each
Closing Date from Gibson, Dunn and Crutcher LLP, counsel for the Company, an

duly organized and is validly existing as a corporation in good standing under
the laws of its state of organization. To the best of such counsel's knowledge,

<PAGE>   15
business organization other than the subsidiary set forth in Exhibit 21 to the
Registration Statement. Each of the Company and its subsidiary is duly qualified
and in good standing as a foreign corporation in each jurisdiction in which the
character or location of its assets or properties (owned, leased or licensed) or
the nature of its businesses makes such qualification necessary, except for such
jurisdictions where the failure to so qualify would not have a material adverse
effect on the assets or properties, business, results of operations, prospects
or condition (financial or otherwise) of the Company or its subsidiary.

                           (ii) Each of the Company and its subsidiary has all
requisite corporate power and authority to own, lease and license its assets and
properties and conduct its business as now being conducted and as described in
the Registration Statement and the Prospectus; and each of the Company and its
subsidiary has all requisite corporate power and authority and all necessary
authorizations, approvals, consents, orders, licenses, certificates and permits
to enter into, deliver and perform this Agreement and to issue and sell the
Shares other than those required under the Securities Act and state and foreign
Blue Sky laws.

Company and its subsidiary have been duly and validly authorized and have been

was issued in violation of any preemptive or other similar right. The Shares
when issued and sold pursuant to this Agreement , will be duly and validly
issued, outstanding, fully paid and nonassessable and none of them will have
been issued in violation of any preemptive or other similar right. To the best
of such counsel's knowledge, except as disclosed in the Registration Statement
and the Prospectus, there is no outstanding option, warrant or other right
calling for the issuance of, and no commitment, plan or arrangement to issue,
any share of stock of the Company or any security convertible into, exercisable
for, or exchangeable for stock of the Company. The Common Stock, the Shares
conform in all material respects to the descriptions thereof contained in the
Registration Statement and the Prospectus.

directors and officers stating that for a period of 180 days from the date of
this Agreement they will not, without the Representatives' prior written

convertible into, exercisable for, or exchangeable for any shares of Common
Stock) owned by them has been duly and validly delivered by such persons and
constitutes the legal, valid and binding obligation of each such person
enforceable against each such person in accordance with its terms, except as the
enforceability thereof may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting the enforcement of
creditors' rights generally and by general equitable principles.

                           (v) All necessary corporate action has been duly and
validly taken by the Company to authorize the execution, delivery and
performance of this Agreement, and the issuance and sale of the Shares. This
Agreement has been duly and validly authorized, executed and delivered by the
Company and this Agreement constitutes the legal, valid and


                                       15


<PAGE>   16
binding obligation of the Company enforceable against the Company in accordance
with their respective terms except (A) as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other similar
laws affecting the enforcement of creditors' rights generally and by general
equitable principles and (B) to the extent that rights to indemnity or
contribution under this Agreement may be limited by Federal or state securities
laws or the public policy underlying such laws.

                           (vi) Neither the execution, delivery and performance
of this Agreement by each of the Company and its subsidiary nor the consummation
of any of the transactions contemplated hereby (including, without limitation,
the issuance and sale by the Company of the Shares) will give rise to a right to
terminate or accelerate the due date of any payment due under, or conflict with

any event which with notice or lapse of time, or both, would constitute a
default) under, or require consent or waiver under, or result in the execution

indenture, mortgage, deed trust, note or other agreement or instrument of which
such counsel is aware and to which the Company or its subsidiary is a party or
by which it or any of its properties or businesses is bound, or any franchise,
license, permit, judgment, decree, order, statute, rule or regulation of which
such counsel is aware or violate any provision of the charter or by-laws of the
Company or its subsidiary.

                           (vii) To the best of such counsel's knowledge, no
default exists, and no event has occurred which with notice or lapse of time, or
both, would constitute a default, in the due performance and observance of any
term, covenant or condition by the Company or its subsidiary of any indenture,
mortgage, deed of trust, note or any other agreement or instrument to which the
Company or its subsidiary is a party or by which it or any of its assets or
properties or businesses may be bound or affected, where the consequences of
such default would have a material and adverse effect on the assets, properties,
business, results of operations, prospects or condition (financial or otherwise)
of the Company or its subsidiary.

                           (viii) To the best of such counsel's knowledge, the
Company nor its subsidiary is in violation of any term or provision of its
charter or by-laws or any franchise, license, permit, judgment, decree, order,
statute, rule or regulation, where the consequences of such violation would have
a material and adverse effect on the assets or properties, businesses, results
of operations, prospects or condition (financial or otherwise) of the Company or
its subsidiary.

                           (ix) No consent, approval, authorization or order of
any court or governmental agency or body is required for the performance of this
Agreement by the Company or its subsidiary or the consummation of the
transactions contemplated hereby or thereby, except such as have been obtained
under the Securities Act and such as may be required under state securities or
Blue Sky laws in connection with the purchase and distribution of the Shares by
the several Underwriters.

                           (x) To the best of such counsel's knowledge, there is
no litigation or governmental or other proceeding or investigation, before any
court or before or by any public body or board pending or threatened against, or
involving the assets, properties or


                                       16


<PAGE>   17
businesses of, the Company or its subsidiary which would have a material adverse
effect upon the assets or properties, business, results of operations, prospects
or condition (financial or otherwise) of the Company or its subsidiary.

                           (xi) The statements in the Prospectus under the
captions "Description of Capital Stock," "Liquidity and Capital Resources,"
"Business," "Shares Eligible for Future Sale," "Management-_____,"
"Management-_____" ["__________"], ["__________"] and "Certain Transactions,"
insofar as such statements constitute a summary of documents referred to therein
or matters of law, are fair summaries in all material respects and accurately
present the information called for with respect to such documents and matters.
All contracts and other documents required to be filed as exhibits to, or
described in, the Registration Statement have been so filed with the Commission
or are fairly described in the Registration Statement, as the case may be.

                           (xii) The Registration Statement, all preliminary

to form in all material respects with the requirements of the Securities Act and
the Rules.

                           (xiii) The Selling Stockholder has full right, power

Stockholder hereunder.

                           (xiv) The Registration Statement has become effective
under the Securities Act, and no stop order suspending the effectiveness of the
Registration Statement has been issued and no proceedings for that purpose have
been instituted or are threatened, pending or contemplated.

               To the extent deemed advisable by such counsel, they may rely as
to matters of fact on certificates of responsible officers of the Company and
public officials and on the opinions of other counsel satisfactory to the
Representatives as to matters which are governed by laws other than the laws of
the State of New York, the General Corporation Law of the State of Delaware and
the Federal laws of the United States; provided that such counsel shall state
that in their opinion the Underwriters and they are justified in relying on such
other opinions. Copies of such certificates and other opinions shall be

respect to the financial statements and notes schedules thereto and other
financial data, as to which such counsel need make no statement) on the date
thereof contained any untrue statement of a material fact or omitted to state a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading.

material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; in case any

the issuance of any stop order and, if issued, to obtain as soon as possible the
withdrawal thereof.

                           (ii) The Company will advise you, promptly after it
shall receive notice or obtain knowledge, of the issuance of any stop order by
the Commission suspending the effectiveness of the Registration Statement or of
the initiation or threat of any proceeding for that purpose; and it will
promptly use its best efforts to prevent the issuance of any stop order or to
obtain its withdrawal at the earliest possible moment if such stop order should
be issued

                           (iii) If, at any time when a prospectus relating to
the Shares is required to be delivered under the Securities Act and the Rules,
any event occurs as a result of which the Prospectus as then amended or
supplemented would include any untrue statement of a material fact or omit to
state any material fact necessary to make the statements therein in the light of
the circumstances under which they were made not misleading, or if it shall be
necessary to amend or supplement the Prospectus to comply with the Securities
Act or the Rules, the Company promptly shall prepare and file with the
Commission, subject to this Section 7, an amendment or supplement which shall
correct such statement or omission or an amendment which shall effect such
compliance.

                           (iv) The Company shall make generally available to
its security holders and to the Representatives as soon as practicable, but not
later than 45 days after the end of the 12-month period beginning at the end of
the fiscal quarter of the Company during which the Effective Date occurs (or 90
days if such 12-month period coincides with the Company's fiscal year), an
earning statement (which need not be audited) of the Company, covering such
12-month period, which shall satisfy the provisions of Section 11(a) of the
Securities Act or Rule 158 of the Rules.

                           (v) The Company will furnish to you, as soon as
available, and, in the case of the Prospectus and any term sheet or abbreviated
term sheet under Rule 434, in no event later than the first (1st) full business
day following the first day that Shares are traded, copies of the Registration
Statement (three of which will be signed and which will include all exhibits),
each Preliminary Prospectus, the Prospectus and any amendments or supplements to
such documents, including any prospectus prepared to permit compliance with
Section 10(a)(3) of the Securities Act, all in such quantities as you may from
time to time reasonably request. Notwithstanding the foregoing, if the
Representatives, on behalf of the several Underwriters, shall agree to the
utilization of Rule 434 of the Rules, the Company shall provide to you copies of
a Preliminary Prospectus updated in all respects through the date specified by
you in such quantities as you may from time to time reasonably request.

                           (vi) The Company will use its best efforts to qualify
the Shares for offering and sale under the securities laws of such jurisdictions
as you may designate and to continue such qualifications in effect for so long
as may be required for purposes of the distribution of the Shares, except that
the Company shall not be required in connection therewith or as a condition
thereof to qualify as a foreign corporation or to execute a general consent to
service of process in any jurisdiction in which it is not otherwise required to
be so qualified or to so execute a general consent to service of process. In
each jurisdiction in which the Shares shall have been qualified as above
provided, the Company will make and file such statements and reports in each
year as are or may be required by the laws of such jurisdiction.

                           (vii) During a period of five (5) years after the
date hereof, the Company will furnish to its shareholders as soon as practicable
after the end of each respective period, annual reports (including financial
statements audited by independent certified public accountants) and unaudited
quarterly reports of operations for each of the first three quarters of the
fiscal year, and will furnish to you and the other several Underwriters
hereunder, upon request (i) concurrently with furnishing such reports to its
shareholders, statements of operations of the Company for each of the first
three (3) quarters in the form furnished to the Company's shareholders, (ii)
concurrently with furnishing to its shareholders, a balance sheet of the Company
as of the end of such fiscal year, together with statements of operations, of
shareholders' equity, and of cash flows of the Company for such fiscal year,
accompanied by a copy of the certificate or report thereon of independent
certified public accountants, (iii) as soon as they are available, copies of all
reports (financial or other) mailed to shareholders, (iv) as soon as they are
available, copies of all reports and financial statements furnished to or filed
with the Commission, any securities exchange or the National Association of
Securities Dealers, Inc. ("NASD"), (v) every material press release and every
material news item or article in respect of the Company or its affairs which was
generally released to shareholders or prepared by the Company or any of its
subsidiaries, and (vi) any additional information of a public nature


                                       20


<PAGE>   21
concerning the Company or its subsidiaries, or its business which you may
reasonably request. During such five (5) year period, if the Company shall have
active subsidiaries, the foregoing financial statements shall be on a
consolidated basis to the extent that the accounts of the Company and its
subsidiaries are consolidated, and shall be accompanied by similar financial
statements for any significant subsidiary which is not so consolidated.

                           (viii) Without the prior written consent of the
Representatives, for a period of 180 days after the date of this Agreement, the
Company shall not issue, sell or register with the Commission, (except for any
registration on Form S-8 or on any successor form) or otherwise dispose of,
directly or indirectly, any equity securities of the Company (or any securities
convertible into or exercisable or exchangeable for equity securities of the
Company), except for the issuance of the Shares pursuant to the Registration
Statement and the issuance of shares pursuant to the Company's existing stock
option plan or bonus plan. In the event that during this period, (i) any shares
are issued pursuant to the Company's existing stock option plan or bonus plan or
(ii) any registration is effected on Form S-8 or on any successor form, the
Company shall obtain the written agreement of such grantee or purchaser or
holder of such registered securities that, for a period of 180 days after the
date of this Agreement, such person will not, without the prior written consent
of the Representatives, offer for sale, sell, distribute, grant any option for
the sale of, or otherwise dispose of, directly or indirectly, or exercise any
registration rights with respect to, any shares of Common Stock (or any
securities convertible into, exercisable for, or exchangeable for any shares of
Common Stock) owned by such person.

                           (ix) On or before completion of this offering, the
Company shall make all filings required under applicable securities laws and by
the NASDAQ National Market System (including any required registration under the
Exchange Act).

                           (x) The Company shall cause to be prepared and
delivered, at its expense, within one business day from the effective date of
this Agreement, to the Representatives an "electronic Prospectus" to be used by
the Underwriters in connection with the offering and sale of the Common Shares.
As used herein, the term "electronic Prospectus" means a form of Prospectus, and
any amendment or supplement thereto, that meets each of the following
conditions: (i) it shall be encoded in an electronic format, satisfactory to the
Representatives, that may be transmitted electronically by the Representatives
to offerees and purchasers of the Common Shares for at least the Prospectus
delivery period; (ii) it shall disclose the same information as the paper
Prospectus and Prospectus filed pursuant to EDGAR, except to the extent that
graphic and image material cannot be disseminated electronically, in which case
such graphic and image material shall be replaced in the electronic Prospectus
with a fair and accurate narrative description or tabular representation of such
material, as appropriate; and (iii) it shall be in or convertible into a paper
format or an electronic format, satisfactory to the Representatives, that will
allow investors to store and have continuously ready access to the Prospectus at
any future time, without charge to investors (other than any fee charged for
subscription to the system as a whole and for on-line time). Such electronic
Prospectus may consist of a Rule 434 preliminary prospectus, together with the
applicable term sheet, provided that it otherwise satisfies the format and
conditions described in the immediately preceding sentence. The Company hereby
confirms that it has included or will include in the Prospectus filed pursuant
to EDGAR or otherwise with the Commission and in the Registration Statement at


                                       21


<PAGE>   22
the time it was declared effective an undertaking that, upon receipt of a
request by an investor or his or her representative within the Prospectus
delivery period, the Company shall transmit or cause to be transmitted promptly,
without charge, a paper copy of the Prospectus.

                           (xi) The Company will apply the net proceeds from the
sale of the Shares being sold by it in the manner set forth under the caption
"Use of Proceeds" in the Prospectus.

                           (xii) The Company will maintain a transfer agent and,
if necessary under the jurisdiction of incorporation of the Company, a registrar
(which may be the same entity as the transfer agent) for its Common Stock.

                           (xiii) If the transactions contemplated hereby are
not consummated by reason of any failure, refusal or inability on the part of
the Company or any Selling Stockholder to perform any agreement on their
respective parts to be performed hereunder or to fulfill any condition of the
Underwriters' obligations hereunder, or if the Underwriters shall terminate this
Agreement pursuant to Section 10, the Company will reimburse the several
Underwriters for all out-of-pocket expenses (including fees and disbursements of
Underwriters' Counsel) incurred by the Underwriters in investigating or
preparing to market or marketing the Shares.

                           (xiv) If at any time during the ninety (90) day
period after the Registration Statement becomes effective, any rumor,
publication or event relating to or affecting the Company shall occur as a
result of which in your opinion the market price of the Common Stock has been or
is likely to be materially affected (regardless of whether such rumor,
publication or event necessitates a supplement to or amendment of the
Prospectus), the Company will, after written notice from you advising the
Company to the effect set forth above, forthwith prepare, consult with you
concerning the substance of and disseminate a press release or other public
statement, reasonably satisfactory to you, responding to or commenting on such
rumor, publication or event.

                           (b) The Company and the Selling Stockholder agrees to
pay, or reimburse if paid by the Representatives, whether or not the
transactions contemplated hereby are consummated or this Agreement is
terminated, all costs and expenses incident to the public offering of the Shares
and the performance of the obligations of the Company under this Agreement
including those relating to: (i) the preparation, printing, filing and
distribution of the Registration Statement including all exhibits thereto, each
preliminary prospectus, the electronic Prospectus, the Prospectus, all
amendments and supplements to the Registration Statement and the Prospectus, and
the printing, filing and distribution of this Agreement, the Agreement Among
Underwriters, the Selected Dealer Agreement, the Underwriter's Questionnaire and
Power of Attorney and any instruments related to any of the foregoing; (ii) the
issuance and delivery of the Shares hereunder to the several Underwriters,
including transfer taxes, if any, and the cost of all certificates representing
the Shares and transfer agents' and registrars' fees; (iii) the registration or
qualification of the Shares for offer and sale under the securities or Blue Sky
laws of the various jurisdictions referred to in Section 7(A)(e), including the
reasonable fees and disbursements of counsel for the Underwriters in connection
with such registration and qualification and the preparation, printing,
distribution and shipment of preliminary and


                                       22


<PAGE>   23
supplementary Blue Sky memoranda; (iv) the furnishing (including costs of
shipping and mailing) to the Representatives and to the Underwriters of copies
of each preliminary prospectus, the Prospectus and all amendments or supplements
to the Prospectus, and of the several documents required by this Section to be
so furnished, as may be reasonably requested for use in connection with the
offering and sale of the Shares by the Underwriters or by dealers to whom Shares
may be sold; (v) the filing fees of the National Association of Securities
Dealers, Inc. in connection with its review of the terms of the public offering;
(vi) the furnishing (including costs of shipping and mailing) to the
Representatives and to the Underwriters of copies of all reports and information
required by Section 7(A)(f); (vii) inclusion of the Shares for quotation on the
NASDAQ National Market System; (viii) the fees and disbursements of counsel for
the Company; (ix) all fees and other charges of the Company's independent
certified public accountants and (x) all transfer taxes, if any, with respect to
the sale and delivery of the Shares by the Company to the Underwriters. Subject
to the provisions of Section 10, the Underwriters agree to pay, whether or not
the transactions contemplated hereby are consummated or this Agreement is
terminated, all costs and expenses incident to the performance of the
obligations of the Underwriters under this Agreement not payable by the Company
pursuant to the preceding sentence, including, without limitation, the fees and
disbursements of counsel for the Underwriters.

               8. Indemnification.

                      (a) The Company agrees to indemnify and hold harmless each
Underwriter and each person, if any, who controls any Underwriter within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act
against any and all losses, claims, damages and liabilities, joint or several
(including any reasonable investigation, legal and other expenses incurred in
connection with, and any amount paid in settlement of, any action, suit or
proceeding or any claim asserted), to which they, or any of them, may become
subject under the Securities Act, the Exchange Act or other Federal or state law
or regulation, at common law or otherwise, insofar as such losses, claims,
damages or liabilities arise out of or are based upon (i) any breach of any
representation, warranty, agreement or covenant of the Company herein or (ii)
any untrue statement or alleged untrue statement of a material fact contained in
any preliminary prospectus, the Registration Statement, the electronic
Prospectus or the Prospectus or any amendment thereof or supplement thereto, or
arise out of or are based upon any omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein not misleading; provided, however, that such indemnity shall
not inure to the benefit of any Underwriter (or any person controlling such
Underwriter) on account of any losses, claims, damages or liabilities arising
from the sale of the Shares to any person by such Underwriter if such untrue
statement or omission or alleged untrue statement or omission was made in such
preliminary prospectus, the Registration Statement or the Prospectus, or such
amendment or supplement, in reliance upon and in conformity with information
furnished in writing to the Company by the Representatives on behalf of any
Underwriter specifically for use therein. This indemnity agreement will be in
addition to any liability which the Company and the Selling Stockholder may
otherwise have.

                      (b) The Selling Stockholder agrees to indemnify and hold
harmless each Underwriter and each person, if any, who controls any Underwriter
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act against any and all losses,


                                       23


<PAGE>   24
claims, damages and liabilities, joint or several (including any reasonable
investigation, legal and other expenses incurred in connection with, and any
amount paid in settlement of, any action, suit or proceeding or any claim
asserted), to which they, or any of them, may become subject under the
Securities Act, the Exchange Act or other Federal or state law or regulation, at
common law or otherwise, insofar as such losses, claims, damages or liabilities
arise out of or are based upon (i) any breach of any representation, warranty,
agreement or covenant of the Company herein or (ii) any untrue statement or
alleged untrue statement of a material fact contained in any preliminary
prospectus, the Registration Statement, the electronic Prospectus or the
Prospectus or any amendment thereof or supplement thereto, or arise out of or
are based upon any omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading; provided, however, that such indemnity shall not inure to the
benefit of any Underwriter (or any person controlling such Underwriter) on
account of any losses, claims, damages or liabilities arising from the sale of
the Shares to any person by such Underwriter if such untrue statement or
omission or alleged untrue statement or omission was made in such preliminary
prospectus, the Registration Statement or the Prospectus, or such amendment or
supplement, in reliance upon and in conformity with information furnished in
writing to the Company by the Representatives on behalf of any Underwriter
specifically for use therein. This indemnity agreement will be in addition to
any liability which the Company and the Selling Stockholder may otherwise have.
The liability of the Selling Stockholder under the representations, warranties
and agreements contained herein and under the indemnity agreements contained in
the provisions of this Section 8 shall be limited to an amount equal to the
initial public offering price of the Shares, if any, sold by the Selling
Stockholder to the Underwriters minus the amount of the underwriting discount
paid thereon to the Underwriters by the Selling Stockholder. The Company and the
Selling Stockholder may agree, as among themselves and without limiting the
rights of the Underwriters under this Agreement, as to the respective amounts of
such liability for which they each shall be responsible.

                      (c) Each Underwriter agrees, severally and not jointly, to
indemnify and hold harmless the Company, each person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act, the Selling Stockholder and each director of the Company and
each officer of the Company who signs the Registration Statement, to the same
extent as the foregoing indemnity from the Company and the Selling Stockholder
to each Underwriter, but only insofar as such losses, claims, damages or
liabilities arise out of or are based upon (i) any breach of any representation,
warranty, agreement or covenant of the Company herein or (ii) any untrue
statement or omission or alleged untrue statement or omission which was made in
any preliminary prospectus, electronic Prospectus, the Registration Statement or
the Prospectus, or any amendment thereof or supplement thereto, contained in the
last paragraph of the cover page, in the paragraph relating to stabilization on
the inside front cover page of the Prospectus and the statements contained under
the caption "Underwriting" in the Prospectus; provided, however, that the
obligation of each Underwriter to indemnify the Company (including any
controlling person, director or officer thereof) shall be limited to the net
proceeds received by the Company from such Underwriter.

                      (d) Any party that proposes to assert the right to be
indemnified under this Section 8 will, promptly after receipt of notice of
commencement of any action, suit or proceeding against such party in respect of
which a claim is to be made against an indemnifying party or parties under this
Section, notify each such indemnifying party of the commencement of


                                       24


<PAGE>   25
such action, suit or proceeding, enclosing a copy of all papers served. No
indemnification provided for in Section 8(a) or 8(b) shall be available to any
party who shall fail to give notice as provided in this Section 8(d) if the
party to whom notice was not given was unaware of the proceeding to which such
notice would have related and was prejudiced by the failure to give such notice
but the omission so to notify such indemnifying party of any such action, suit
or proceeding shall not relieve it from any liability that it may have to any
indemnified party for contribution or otherwise than under this Section 8. In
case any such action, suit or proceeding shall be brought against any
indemnified party and it shall notify the indemnifying party of the commencement
thereof, the indemnifying party shall be entitled to participate in, and, to the
extent that it shall wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel reasonably satisfactory to
such indemnified party, and after notice from the indemnifying party to such
indemnified party of its election so to assume the defense thereof and the
approval by the indemnified party of such counsel, the indemnifying party shall
not be liable to such indemnified party for any legal or other expenses, except
as provided below and except for the reasonable costs of investigation
subsequently incurred by such indemnified party in connection with the defense
thereof. The indemnified party shall have the right to employ its counsel in any
such action, but the fees and expenses of such counsel shall be at the expense
of such indemnified party unless (i) the employment of counsel by such
indemnified party has been authorized in writing by the indemnifying parties,
(ii) the indemnified party shall have reasonably concluded that there may be a
conflict of interest between the indemnifying parties and the indemnified party
in the conduct of the defense of such action (in which case the indemnifying
parties shall not have the right to direct the defense of such action on behalf
of the indemnified party) or (iii) the indemnifying parties shall not have
employed counsel to assume the defense of such action within a reasonable time
after notice of the commencement thereof, in each of which cases the fees and
expenses of counsel shall be at the expense of the indemnifying parties. An
indemnifying party shall not be liable for any settlement of any action, suit,
proceeding or claim effected without its written consent.

                           (e) The parties to this Agreement hereby acknowledge
that they are sophisticated business persons who were represented by counsel
during the negotiations regarding the provisions hereof including, without
limitation, the provisions of this Section 8, and are fully informed regarding
said provisions. They further acknowledge that the provisions of this Section 8
fairly allocate the risks in light of the ability of the parties to investigate
the Company and its business in order to assure that adequate disclosure is made
in the Registration Statement and Prospectus as required by the Securities Act
and the Exchange Act.

                      9. Contribution. In order to provide for just and
equitable contribution in circumstances in which the indemnification provided
for in Section 8(a) is due in accordance with its terms but for any reason is
held to be unavailable from the Company or the Selling Stockholder, the Company,
the Selling Stockholder, and the Underwriters shall contribute to the aggregate
losses, claims, damages and liabilities (including any investigation, legal and
other expenses reasonably incurred in connection with, and any amount paid in
settlement of, any action, suit or proceeding or any claims asserted, but after
deducting any contribution received by the Company or the Selling Stockholder
from persons other than the Underwriters, such as persons who control the
Company within the meaning of the Securities Act, officers of the Company who
signed the Registration Statement and directors of the Company, who may also be
liable for contribution) to which the Company, the Selling Stockholder and one
or more of the


                                       25


<PAGE>   26
Underwriters may be subject in such proportion as is appropriate to reflect the
relative benefits received by the Company and the Selling Stockholder on the one
hand and the Underwriters on the other from the offering of the Shares or, if
such allocation is not permitted by applicable law or indemnification is not
available as a result of the indemnifying party not having received notice as
provided in Section 8 hereof, in such proportion as is appropriate to reflect
not only the relative benefits referred to above but also the relative fault of
the Company and the Selling Stockholder on the one hand and the Underwriters on
the other in connection with the statements or omissions which resulted in such
losses, claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative benefits received by the Company and the
Underwriters shall be deemed to be in the same proportion as (x) the total
proceeds from the offering (net of underwriting discounts but before deducting
expenses) received by the Company, as set forth in the table on the cover page
of the Prospectus, bear to (y) the underwriting discounts received by the
Underwriters, as set forth in the table on the cover page of the Prospectus. The
relative fault of the Company and the Selling Stockholder or the Underwriters
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact related to information supplied by
the Company or the Selling Stockholder or the Underwriters and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company, the Selling Stockholder and the
Underwriters agree that it would not be just and equitable if contribution
pursuant to this Section 9 were determined by pro rata allocation (even if the
Underwriters were treated as one entity for such purpose) or by any other method
of allocation which does not take account of the equitable considerations
referred to above. Notwithstanding the provisions of this Section 9, (i) in no
case shall any Underwriter (except as may be provided in the Agreement Among
Underwriters) be liable or responsible for any amount in excess of the
underwriting discount applicable to the Shares purchased by such Underwriter
hereunder, and (ii) the Company and the Shareholder shall be liable and
responsible for any amount in excess of such underwriting discount; provided,
however, that no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 9, each person, if any, who
controls an Underwriter within the meaning of Section 15 of the Securities Act
or Section 20(a) of the Exchange Act shall have the same rights to contribution
as such Underwriter, and each person, if any, who controls the Company within
the meaning of the Section 15 of the Securities Act or Section 20(a) of the
Exchange Act, each officer of the Company who shall have signed the Registration
Statement and each director of the Company shall have the same rights to
contribution as the Company, subject in each case to clauses (i) and (ii) in the
immediately preceding sentence of this Section 9. Any party entitled to
contribution will, promptly after receipt of notice of commencement of any
action, suit or proceeding against such party in respect of which a claim for
contribution may be made against another party or parties under this Section,
notify such party or parties from whom contribution may be sought, but the
omission so to notify such party or parties from whom contribution may be sought
shall not relieve the party or parties from whom contribution may be sought from
any other obligation it or they may have hereunder or otherwise than under this
Section. No party shall be liable for contribution with respect to any action,
suit, proceeding or claim settled without its written consent. The Underwriter's
obligations to contribute pursuant to this Section 9 are several in proportion
to their respective underwriting commitments and not joint.

               10. Termination. This Agreement may be terminated with respect to
the Shares to be purchased on a Closing Date by the Representatives by notifying
the Company at any time:

                      (a) in the absolute discretion of the Representatives at
or before any Closing Date: (i) if on or prior to such date, any domestic or
international event or act or occurrence has materially disrupted, or in the
opinion of the Representatives will in the future materially disrupt, the
securities markets; (ii) if there has occurred any new outbreak or material
escalation of hostilities or other calamity or crisis the effect of which on the
financial markets of the United States is such as to make it, in the judgment of
the Representatives, inadvisable to proceed with the offering; (iii) if there
shall be such a material adverse change in general financial, political or
economic conditions or the effect of international conditions on the financial
markets in the United States is such as to make it, in the judgment of the
Representatives, inadvisable or impracticable to market the Shares; (iv) if
trading in the Shares has been suspended by the Commission or trading generally
on the New York Stock Exchange, Inc. or on the American Stock Exchange, Inc. has
been suspended or limited, or minimum or maximum ranges for prices for
securities shall have been fixed, or maximum ranges for prices for securities
have been required, by said exchanges or by order of the Commission, the
National Association of Securities Dealers, Inc., or any other governmental or
regulatory authority; or (v) if a banking moratorium has been declared by any
state or Federal authority, or

                      (b) at or before any Closing Date, that any of the
conditions specified in Section 6 shall not have been fulfilled when and as
required by this Agreement.

               If this Agreement is terminated pursuant to any of its
provisions, the Company shall not be under any liability to any Underwriter, and
no Underwriter shall be under any liability to the Company, except that (y) if
this Agreement is terminated by the Representatives or the Underwriters because
of any failure, refusal or inability on the part of the Company to comply with
the terms or to fulfill any of the conditions of this Agreement, the Company
will reimburse the Underwriters for all out-of-pocket expenses (including the
reasonable fees and disbursements of their counsel) incurred by them in
connection with the proposed purchase and sale of the Shares or in contemplation
of performing their obligations hereunder and (z) no Underwriter who shall have
failed or refused to purchase the Shares agreed to be purchased by it under this
Agreement, without some reason sufficient hereunder to justify cancellation or
termination of its obligations under this Agreement, shall be relieved of
liability to the Company or to the other Underwriters for damages occasioned by
its failure or refusal.

               11. Substitution of Underwriters. If one or more of the
Underwriters shall fail (other than for a reason sufficient to justify the
cancellation or termination of this Agreement under Section 10) to purchase on
any Closing Date the Shares agreed to be purchased on such Closing Date by such
Underwriter or Underwriters, the Representatives may find one or more substitute
underwriters to purchase such Shares or make such other arrangements as the
Representatives may deem advisable or one or more of the remaining Underwriters
may agree to purchase such Shares in such proportions as may be approved by the
Representatives, in each case upon the terms set forth in this Agreement. If no

                      (a) if the number of Shares to be purchased by the
defaulting Underwriters on such Closing Date shall not exceed 10% of the Shares
that all the Underwriters are obligated to purchase on such Closing Date, then
each of the nondefaulting Underwriters shall be obligated to purchase such
Shares on the terms herein set forth in proportion to their respective
obligations hereunder; provided, that in no event shall the maximum number of
Shares that any Underwriter has agreed to purchase pursuant to Section 1 be
increased pursuant to this Section 11 by more than one-ninth of such number of
Shares without the written consent of such Underwriter; or

                      (b) if the number of Shares to be purchased by the
defaulting Underwriters on such Closing Date shall exceed 10% of the Shares that
all the Underwriters are obligated to purchase on such Closing Date, then the
Company shall be entitled to an additional business day within which it may, but
is not obligated to, find one or more substitute underwriters reasonably
satisfactory to the Representatives to purchase such Shares upon the terms set
forth in this Agreement.

               In any such case, either the Representatives or the Company shall
have the right to postpone the applicable Closing Date for a period of not more
than five business days in order that necessary changes and arrangements
(including any necessary amendments or supplements to the Registration Statement
or Prospectus) may be effected by the Representatives and the Company. If the
number of Shares to be purchased on such Closing Date by such defaulting
Underwriter or Underwriters shall exceed 10% of the Shares that all the
Underwriters are obligated to purchase on such Closing Date, and none of the
nondefaulting Underwriters or the Company shall make arrangements pursuant to
this Section within the period stated for the purchase of the Shares that the
defaulting Underwriters agreed to purchase, this Agreement shall terminate with
respect to the Shares to be purchased on such Closing Date without liability on
the part of any nondefaulting Underwriter to the Company and without liability
on the part of the Company, except in both cases as provided in Sections 7, 8, 9
and 10. The provisions of this Section shall not in any way affect the liability
of any defaulting Underwriter to the Company or the nondefaulting Underwriters
arising out of such default. A substitute underwriter hereunder shall become an
Underwriter for all purposes of this Agreement.

               12. Miscellaneous. The respective agreements, representations,
warranties, indemnities and other statements of the Company or its officers, the
Selling Stockholder and of the Underwriters set forth in or made pursuant to
this Agreement shall remain in full force and effect, regardless of any
investigation made by or on behalf of any Underwriter, the Selling Stockholder
or the Company or any of the officers, directors or controlling persons referred
to in Sections 8 and 9 hereof, and shall survive delivery of and payment for the
Shares. The provisions of Sections 7, 8, 9 and 10 shall survive the termination
or cancellation of this Agreement.

               This Agreement has been and is made for the benefit of the
Underwriters, the Selling Stockholder and the Company and their respective
successors and assigns, and, to the extent expressed herein, for the benefit of
persons controlling any of the Underwriters, or the Company, and directors and
officers of the Company, and their respective successors and assigns, and no
other person shall acquire or have any right under or by virtue of this
Agreement.

<PAGE>   4

        Prompt notice shall be given of the taking of any other corporate action
approved by shareholders without a meeting by less than a unanimous written
consent to those shareholders entitled to vote who have not consented in
writing.

        Notwithstanding any of the foregoing provisions of this section, and
except as provided in Article III, Section 4 of these bylaws, directors may not
be elected by written consent except by the unanimous written consent of all
shares entitled to vote for the election of directors.

        A written consent may be revoked by a writing received by the
corporation prior to the time that written consents of the number of shares
required to authorize the proposed action have been filed with the secretary of
the corporation, but may not be revoked thereafter. Such revocation is effective
upon its receipt by the secretary of the Corporation.

SECTION 8. QUORUM AND SHAREHOLDER ACTION

        A majority of the shares entitled to vote, represented in person or by
proxy, shall constitute a quorum at a meeting of shareholders. If a quorum is
present, the affirmative vote of the majority of shareholders represented at the
meeting and entitled to vote on any matter shall be the act of the shareholders,
unless the vote of a greater number is required by law and except as provided in
the following paragraphs of this section.

        The shareholders present at a duly called or held meeting at which a
quorum is present may continue to transact business until adjournment
notwithstanding the withdrawal of enough shareholders to leave less than a
quorum, if any action is approved by at least a majority of the shares required
to constitute a quorum.

        In the absence of a quorum any meeting of shareholders may be adjourned
from time to time by the vote of a majority of the shares represented either in
person or by proxy, but no other business may be transacted except as provided
in the foregoing provisions of this section.

SECTION 9. VOTING

        Only shareholders of record on the record date fixed for voting purposes
by the board of directors pursuant to Article III Section 3 of these bylaws, or,
if there be no such date fixed, on the record date given below, shall by
entitled to vote at a meeting.

        If no record date is fixed:

        a. The record date for determining shareholders entitled to notice of,
or to vote at a meeting of shareholders, shall be at the close of business on
the business day next preceding the day on which notice is given or, if notice
is waived, at the close of business on the business day next preceding the day
on which the meeting is held.

        b. The record date for determining the shareholders entitled to give
consent to corporate actions in writing without a meeting, when no prior action
by the board is necessary, shall be the day on which the first written consent
is given.


                                       4
<PAGE>   5

        c. The record date for determining shareholders for any other purpose
shall be at the close of business on the day on which the board adopts the
resolution relating thereto, or the 60th day prior to the date of such other
action, whichever is later.

        Every shareholder entitled to vote shall be entitled to one vote for
each share held, except as otherwise provided by law, by the Articles of
Incorporation or by other provisions of these bylaws. Except with respect to
elections of directors, any shareholder entitled to vote may vote part of his or
her shares in favor of a proposal and refrain from voting the remaining shares
or vote them against the proposal. If a shareholder fails to specify the number
of shares he or she is affirmatively voting, it will be conclusively presumed
that the shareholder's approving vote is with respect to all shares the
shareholder is entitled to vote.

        At each election of directors, shareholders shall not be entitled to
cumulate votes unless the candidates' names have been placed in nomination
before the commencement of the voting and a shareholder has given notice at the
meeting, and before the voting has begun, of his or her intention to cumulate
votes. If any shareholder has given such notice, then all shareholders entitled
to vote may cumulate their votes by giving one candidate a number of votes equal
to the number of directors to be elected multiplied by the number of his or her
shares or by distributing such votes on the same principle among any number of
candidates as he or she thinks fit. The candidates receiving the highest number
of votes, up to the number of directors to be elected, shall be elected. Votes
cast against a candidate or which are withheld shall have no effect. Upon the
demand of any shareholder made before the voting begins, the election of
directors shall be by ballot rather than by voice vote.

SECTION 10. PROXIES

        Every person entitled to vote shares may authorize another person or
persons to act by proxy with respect to such shares by filing a written proxy
with the secretary of the corporation, executed by such person or his or her
duly authorized agent.

        A proxy shall not be valid after the expiration of eleven (11) months
from the date thereof unless otherwise provided in the proxy. Every proxy shall
continue in full force and effect until revoked by the person executing it prior
to the vote pursuant thereto, except as otherwise provided in Section 705 of the
California Corporations Code.


                                   ARTICLE III
                                    DIRECTORS

SECTION 1. POWERS

        The authorized number of directors shall be two until changed by
amendment to this article of these bylaws.

        After issuance of shares, this bylaw may only be amended by approval of
a majority of the outstanding shares entitled to vote; provided, moreover, that
a bylaw reducing the fixed number of directors to a number less than five (5)
cannot be adopted unless in accordance with the additional requirements of
Article IX of these Bylaws.

SECTION 3. ELECTION AND TENURE OF OFFICE

        The directors shall by elected at the annual meeting of the shareholders
and hold office until the next annual meeting and until their successors have
been elected and qualified.

SECTION 4. VACANCIES

        A vacancy on the board of directors shall exist in the case of death,
resignation, or removal of any director or in case the authorized number of
directors is increased, or in case the shareholders fail to elect the full
authorized number of directors at any annual or special meeting of the
shareholders at which any director is elected. The board of directors may
declare vacant the office of a director who has been declared of unsound mind by
an order of court or who has been convicted of a felony.

        Except for a vacancy created by the removal of a director, vacancies on
the board of directors may be filled by approval of the board or if the number
of directors then in office is less than a quorum, by (1) the unanimous written
consent of the directors then in office, (2) the affirmative vote of a majority
of the directors then in office at a meeting held pursuant to notice or waivers
of notice complying with this Article of these Bylaws, or (3) a sole remaining
director. Vacancies occurring on the board by reason of the removal of directors
may be filled only by approval of the shareholders. Each director so elected
shall hold office until the next annual meeting of the shareholders and until
his or her successor has been elected and qualified.

        The shareholders may elect a director at any time to fill a vacancy not
filled by the directors. Any such election by written consent other than to fill
a vacancy created by the removal of a director requires the consent of a
majority of the outstanding shares entitled to vote.

        Any director may resign effective upon giving written notice to the
chairperson of the board of directors, the president, the secretary or to the
board of directors unless the notice specifies a later time for the
effectiveness of the resignation. If the resignation is effective at a later
time, a successor may be elected to take office when the resignation becomes
effective. Any reduction of the authorized number of directors does not remove
any director prior to the expiration of such director's term in office.

<PAGE>   7

SECTION 5. REMOVAL

        Any or all of the directors may be removed without cause if such removal
is approved by a majority of the outstanding shares entitled to vote, subject to
the provisions of Section 303 of the California Corporations Code. Except as
provided in Sections 302, 303 and 304 of the California Corporations Code, a
director may not be removed prior to the expiration of such director's term of
office.

        The Superior Court of the proper county may, on the suit of shareholders
holding at least 10 percent of the number of outstanding shares of any class,
remove from office any director in case of fraudulent or dishonest acts or gross
abuse of authority or discretion with reference to the corporation and may bar
from re-election any director so removed for a period prescribed by the court.
The corporation shall be made a party to such action.

SECTION 6. PLACE OF MEETINGS

        Meetings of the board of directors shall be held at any place, within or
without the State of California, which has been designated in the notice of the
meeting or, if not stated in the notice or if there is no notice, at the
principal executive office of the corporation or as may be designated from time

adjournment to another time or place shall be given before the time of the
resumed meeting to all directors who were not present at the time of adjournment
of the original meeting.

SECTION 8. QUORUM AND BOARD ACTION

        A quorum for all meetings of the board of directors shall consist of a
majority of the members of the board of directors until changed by amendment to
this article of these bylaws.

                                       7
<PAGE>   8

        Every act or decision done or made by a majority of the directors
present at a meeting duly held at which a quorum is present is the act of the
board, subject to the provisions of Section 310 (relating to the approval of
contracts and transactions in which a director has a material financial
interest); the provisions of Section 311 (designation of committees); and
Section 317(e) (indemnification of directors) of the California Corporations
Code. A meeting at which a quorum is initially present may continue to transact
business notwithstanding the withdrawal of directors, if any action taken is
approved by at least a majority of the required quorum for such meeting.

        A majority of the directors present at a meeting may adjourn any meeting
to another time and place, whether or not a quorum is present at the meeting.

SECTION 9. WAIVER OF NOTICE

or wherever held, are as valid as though undertaken at a meeting duly held after

written consent shall have the same force and effect as a unanimous vote of the
directors.

SECTION 11. COMPENSATION

resolution, the board of directors may allot a reasonable fixed sum and expenses
to be paid for attendance at regular or special meetings. Nothing contained

capacity and receiving compensation therefor. Members of special of standing
committees may be allowed like compensation for attendance at meetings.

               SECTION 2.01 Annual Meetings. Annual meetings of the stockholders
of the Corporation for the purpose of electing directors and for the transaction

<PAGE>   2


such purpose, then at his post office address last known to the Secretary.
Except as otherwise expressly required by law, no publication of any notice of a
meeting of the stockholders shall be required. Every notice of a meeting of the
stockholders shall state the place, date and hour of the meeting, and, in the
case of a special meeting, shall also state the purpose or purposes for which
the meeting is called. Notice of any meeting of stockholders shall not be
required to be given to any stockholder who shall have waived such notice and
such notice shall be deemed waived by any stockholder who shall attend such
meeting in person or by proxy, except as a stockholder who shall attend such
meeting for the express purpose of objecting, at the beginning of the meeting,
to the transaction of any business because the meeting is not lawfully called or
convened. Except as otherwise expressly required by law, notice of any adjourned
meeting of the stockholders need not be given if the time and place thereof are
announced at the meeting at which the adjournment is taken.

               SECTION 2.05 Quorum. Except in the case of any meeting for the
election of directors summarily ordered as provided by law, the holders of
record of a majority in voting interest of the shares of stock of the
Corporation entitled to be voted thereat, present in person or by proxy, shall
constitute a quorum for the transaction of business at any meeting of the
stockholders of the Corporation or any adjournment thereof. In the absence of a
quorum at any meeting or any adjournment thereof, a majority in voting interest
of the stockholders present in person or by proxy and entitled to vote thereat
or, in the absence therefrom of all the stockholders, any officer entitled to
preside at, or to act as secretary of, such meeting may adjourn such meeting
from time to time. At any such adjourned meeting at which a quorum is present
any business may be transacted which might have been transacted at the meeting
as originally called.

               SECTION 2.06  Voting.

               (a) Each stockholder shall, at each meeting of the stockholders,
be entitled to vote in person or by proxy each share or fractional share of the
stock of the Corporation having voting rights on the matter in question and
which shall have been held by him and registered in his name on the books of the
Corporation:

                       (i) on the date fixed pursuant to Section 6.05 of these
               Bylaws as the record date for the determination of stockholders
               entitled to notice of and to vote at such meeting, or

                      (ii) if no such record date shall have been so fixed, then
               (a) at the close of business on the day next preceding the day on
               which notice of the meeting shall be given or (b) if notice of
               the meeting shall be waived, at the close of business on the day
               next preceding the day on which the meeting shall be held.

               (b) Shares of its own stock belonging to the Corporation or to
another corporation, if a majority of the shares entitled to vote in the
election of directors in such other corporation is held, directly or indirectly,
by the Corporation, shall neither be entitled to vote nor be counted for quorum
purposes. Persons holding stock of the Corporation in a fiduciary 


                                      2

<PAGE>   3

capacity shall be entitled to vote such stock. Persons whose stock is pledged
shall be entitled to vote, unless in the transfer by the pledgor on the books of
the Corporation he shall have expressly empowered the pledgee to vote thereon,
in which case only the pledgee, or his proxy, may represent such stock and vote
thereon. Stock having voting power standing of record in the names of two or
more persons, whether fiduciaries, members of a partnership, joint tenants in
common, tenants by entirety or otherwise, or with respect to which two or more
persons have the same fiduciary relationship, shall be voted in accordance with
the provisions of the General Corporation Law of the State of Delaware.

               (c) Any such voting rights may be exercised by the stockholder
entitled thereto in person or by his proxy appointed by an instrument in
writing, subscribed by such stockholder or by his attorney thereunto authorized
and delivered to the secretary of the meeting; provided, however, that no proxy
shall be voted or acted upon after three years from its date unless said proxy
shall provide for a longer period. The attendance at any meeting of a
stockholder who may theretofore have given a proxy shall not have the effect of
revoking the same unless he shall in writing so notify the secretary of the
meeting prior to the voting of the proxy. At any meeting of the stockholders all
matters, except as otherwise provided in the Certificate of Incorporation, in
these Bylaws or by law, shall be decided by the vote of a majority in voting
interest of the stockholders present in person or by proxy and entitled to vote
thereat and thereon, a quorum being present. The vote at any meeting of the
stockholders on any question need not be by ballot, unless so directed by the
chairman of the meeting. On a vote by ballot each ballot shall be signed by the
stockholder voting, or by his proxy, if there be such proxy, and it shall state
the number of shares voted.

               SECTION 2.07 List of Stockholders. The Secretary of the
Corporation shall prepare and make, at least ten (10) days before every meeting
of stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten (10) days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by any stockholder who is
present.

               SECTION 2.08 Judges. If at any meeting of the stockholders a vote
by written ballot shall be taken on any question, the chairman of such meeting
may appoint a judge or judges to act with respect to such vote. Each judge so
appointed shall first subscribe an oath faithfully to execute the duties of a
judge at such meeting with strict impartiality and according to the best of his
ability. Such judges shall decide upon the qualification of the voters and shall
report the number of shares represented at the meeting and entitled to vote on
such question, shall conduct and accept the votes, and, when the voting is
completed, shall ascertain and report the number of shares voted respectively
for and against the question. Reports of judges shall be in writing and
subscribed and delivered by them to the Secretary of the Corporation. The judges
need not be stockholders of the Corporation, and any officer of the Corporation
may be a judge 



                                       3
<PAGE>   4

on any question other than a vote for or against a proposal in which he shall
have a material interest.

               SECTION 2.09 Action Without Meeting. Any action required to be
taken at any annual or special meeting of stockholders of the Corporation, or
any action that may be taken at any annual or special meeting of such
stockholders, may be taken without a meeting, without prior notice and without a
vote, if a consent in writing, setting forth the action so taken, shall be
signed by the holders of outstanding stock having not less than the minimum
number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted.
Prompt notice of the taking of the corporate action without a meeting by less
than unanimous written consent shall be given to those stockholders who have not
consented in writing. Notwithstanding the foregoing, if at any time the
Corporation shall have a class of stock registered pursuant to the provisions of
the Securities Exchange Act of 1934, as amended, for so long as such class is so
registered, any action by the stockholders of such class must be taken at an
annual or special meeting of stockholders and may not be taken by written
consent.

               SECTION 2.10 Advance Notice of Stockholder Business. At any
meeting of the stockholders, only such business shall be conducted as shall have
been brought before the meeting (i) by or at the direction of the Board or (ii)
by any stockholder of the Corporation who complies with the notice procedures
set forth in this Section 2.10 and Section 2.11 of Article II. For business to
be properly brought before any meeting of the stockholders by a stockholder, the
stockholder must have given notice thereof in writing to the Secretary of the
Corporation not less than 90 days in advance of such meeting or, if later, the
tenth day following the first public announcement of the date of such meeting,
and such business must be a proper matter for stockholder action under the
General Corporation Law of the State of Delaware. A stockholder's notice to the
Secretary shall set forth as to each matter the stockholder proposes to bring
before the meeting (1) a brief description of the business desired to be brought
before the meeting and the reasons for conducting such business at the meeting,
(2) the name and address, as they appear on the Corporation's books, of the
stockholder proposing such business, (3) the class and number of shares of the
Corporation that are beneficially owned by the stockholder, and (4) any material
interest of the stockholder in such business. In addition, the stockholder
making such proposal shall promptly provide any other information reasonably
requested by the Corporation. The chairman of any such meeting shall have the
power and the duty to determine whether any business proposed to be brought
before the meeting has been made in accordance with the procedure set forth in
these Bylaws and shall direct that any business not properly brought before the
meeting shall not be considered. Notwithstanding anything in these Bylaws to the
contrary, no business shall be conducted at any meeting of the stockholders
except in accordance with the procedures set forth in this Section 2.10 and
Section 2.11 of Article II. For purposes of this Section 2.10 and Section 2.11
of Article II, "public announcement" shall mean disclosure in a press release
reported by the Dow Jones News Service, Associated Press or a comparable
national news service or in a document publicly filed by the Corporation with
the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of
the Securities Exchange Act of 1934, as amended, or any successor provision.

               SECTION 2.11 Advance Notice of Stockholder Nominees. Nominations
for the election of directors may be made by the Board or by any stockholder
entitled to vote in the election of directors; provided, however, that a
stockholder may nominate a person for election as a director at a meeting only
if written notice of such stockholder's intent to make such nomination has been
given to the Secretary of the Corporation not later than 90 days in advance of
such meeting or, if later, the tenth day following the first public announcement
of the date of such meeting. Each such notice shall set forth: (i) the name and
address of the stockholder who intends to make the nomination and of the person
or persons to be nominated; (ii) a representation that the stockholder is a
holder of record of stock of the Corporation entitled to vote at such meeting
and intends to appear in person or by proxy at the meeting and nominate the
person or persons specified in the notice; (iii) a description of all
arrangements or understandings between the stockholder and each nominee and any
other person or persons (naming such person or persons) pursuant to which the
nomination or nominations are to be made by the stockholder, (iv) such other
information regarding each nominee proposed by such stockholder as would be
required to be included in a proxy statement filed pursuant to the proxy rules
of the Securities and Exchange Commission had the nominee been nominated, or
intended to be nominated, by the Board; and (v) the consent of each nominee to
serve as a director of the Corporation if so elected. In addition, the
stockholder making such nomination shall promptly provide any other information
reasonably requested by the Corporation. Notwithstanding the foregoing
provisions of this Section 2.11 of Article II, in the event that the number of
directors to be elected to the Board is increased and there is no public
announcement naming either all of the nominees for director or specifying the
size of the increased Board made by the Corporation at least 100 days in advance
of such meeting, a stockholder's notice required by this Section 2.11 of Article
II shall be considered timely, but only with respect to nominees for any new
positions created by such increase, if it shall be delivered to the Secretary of
the Corporation not later than the tenth day following the day on which such
public announcement is first made by the Corporation. No person shall be
eligible for election as a director of the Corporation unless nominated in
accordance with the procedures set forth in this Section 2.11 of Article II. The
chairman of any meeting of stockholders shall have the power and the duty to
determine whether a nomination has been made in accordance with the procedure
set forth in this Section 2.11 of Article II and shall direct that any
nomination not made in accordance with these procedures be disregarded.

                                   ARTICLE III

his successor shall have been duly elected and shall qualify or until he shall
resign or shall have been removed in the manner hereinafter provided.

               SECTION 3.03 Election of Directors. Subject to the provisions of
the Certificate of Incorporation, the Board of Directors shall be classified
into three classes and the members of each class shall serve for a term of three
years. At the first annual meeting of stockholders, one-third of the directors
shall be elected for a term of three years, one-third of the directors shall be
elected for a term of two years and one-third of the directors shall be elected
for a term of one year. If the number of directors is not divisible by three,
the first extra director shall be elected for a term of three years and the
second extra director, if any, shall be elected for a term of two years. At any
subsequent annual meeting of stockholders, a number of directors shall be
elected equal to the number of directors with terms expiring at that annual
meeting. Directors elected at each such annual meeting shall be elected for a
term expiring with the annual meeting of stockholders three years thereafter.
There shall be no right with respect to the shares of stock of the Corporation
to cumulate votes in the election of directors.

               SECTION 3.04 Resignations. Any director of the Corporation may
resign at any time by giving written notice to the Board or to the Secretary of
the Corporation. Any such resignation shall take effect at the time specified
therein, or, if the time be not specified, it shall take effect immediately upon
its receipt; and unless otherwise specified therein, the acceptance of such
resignation shall not be necessary to make it effective.

               SECTION 3.05 Vacancies. Except as otherwise provided in the
Certificate of Incorporation, any vacancy in the Board, whether because of
death, resignation, disqualification, an increase in the number of directors, or
any other cause, may be filled by vote of the majority of the remaining
directors, although less than a quorum. Each director so chosen to fill a
vacancy shall hold office until his successor shall have been elected and shall
qualify or until he shall resign or shall have been removed in the manner
hereinafter provided. If at any time the corporation should have no directors in
office, then any officer or any stockholder or an executor, administrator,
trustee or guardian of a stockholder, may call a special meeting of stockholders
in accordance with the provisions of the certificate of incorporation and these
bylaws, or may apply to the Court of Chancery for a decree summarily ordering an
election as provided in Section 211 of the General Corporation Law of Delaware.

               SECTION 3.06 Place of Meeting, Etc. The Board may hold any of its
meetings at such place or places within or without the State of Delaware as the
Board may from time to time by resolution designate or as shall be designated by
the person or persons calling the meeting or in the notice or a waiver of notice
of any such meeting. Directors may participate in any regular or special meeting
of the Board by means of conference telephone or similar communications
equipment pursuant to which all persons participating in the meeting of the
Board can hear each other, and such participation shall constitute presence in
person at such meeting.

               SECTION 3.07 First Meeting. The Board shall meet as soon as
practicable after each annual election of directors and notice of such first
meeting shall not be required.

               SECTION 3.08 Regular Meetings. Regular meetings of the Board may
be held at such times as the Board shall from time to time by resolution
determine. If any day fixed for a regular meeting shall be a legal holiday at
the place where the meeting is to be held, then 



                                       6
<PAGE>   7

the meeting shall be held at the same hour and place on the next succeeding
business day not a legal holiday. Except as provided by law, notice of regular
meetings need not be given.

               SECTION 3.09 Special Meetings. Special meetings of the Board
shall be held whenever called by the President, the Chairman of the Board or a
majority of the authorized number of directors. Except as otherwise provided by
law or by these Bylaws, notice of the time and place of each such special
meeting shall be mailed to each director, addressed to him at his residence or
usual place of business, at least five (5) days before the day on which the
meeting is to be held, or shall be sent to him or her at such place via
facsimile or be delivered personally or by telephone not less than forty-eight
(48) hours before the time at which the meeting is to be held. Except where
otherwise required by law or by these Bylaws, notice of the purpose of a special
meeting need not be given. Notice of any meeting of the Board shall not be
required to be given to any director who shall have waived such notice and such
notice shall be deemed waived by any director who shall attend such meeting,
except a director who shall attend such meeting for the express purpose of
objecting, at the beginning of the meeting, to the transaction of any business
because the meeting is not lawfully called or convened.

               SECTION 3.10 Quorum and Manner of Acting. Except as otherwise
provided in these Bylaws, the presence of a majority of the authorized number of
directors shall be required to constitute a quorum for the transaction of
business at any meeting of the Board, and all matters shall be decided at any
such meeting, a quorum being present, by the affirmative votes of a majority of
the directors present. In the absence of a quorum, a majority of directors
present at any meeting may adjourn the same from time to time until a quorum
shall be present. Notice of any adjourned meeting need not be given. The
directors shall act only as a Board, and the individual directors shall have no
power as such.

               SECTION 3.11 Action by Consent. Any action required or permitted
to be taken at any meeting of the Board or of any committee thereof may be taken
without a meeting if a written consent thereto is signed by all members of the
Board or of such committee, as the case may be, and such written consent is
filed with the minutes of proceedings of the Board or committee.

               SECTION 3.12 Removal of Directors. Subject to the provisions of
the Certificate of Incorporation, any director may be removed at any time, but
only for cause and only by the affirmative vote of the stockholders having 80%
of the total number of shares of the Corporation entitled to vote thereon, but
only if notice of such proposal was contained in the notice of the stockholders'
meeting.

               SECTION 3.13 Compensation. The directors shall receive only such
compensation for their services as directors as may be allowed by resolution of
the Board. The Board may also provide that the Corporation shall reimburse each
such director for any expense incurred by him because of his attendance at any
meetings of the Board or Committees of the Board. Neither the payment of such
compensation nor the reimbursement of such expenses shall be construed to
preclude any director from serving the Corporation or its subsidiaries in any
other capacity and receiving compensation therefor.

limited by law, shall have and may exercise all the powers and authority of the
Board in the management of the business and affairs of the Corporation, and may
authorize the seal of the Corporation to be affixed to all papers that may
require it. Any such committee shall keep written minutes of its meetings and
report the same to the Board at the next regular meeting of the Board. In the
absence or disqualification of a member of a committee, the member or members
thereof present at any meeting and not disqualified from voting, whether or not
he or they constitute a quorum, may unanimously appoint another member of the
Board to act at the meeting in the place of any such absent or disqualified
member.

any officer or officers, assistant or assistants, agent or agents, or attorney
or attorneys of the Corporation to whom such power shall have been delegated by
the Board. The Board may make such special rules and regulations with respect to
such bank accounts, not inconsistent with the provisions of these Bylaws, as it

                                   ARTICLE VI

                            SHARES AND THEIR TRANSFER

               SECTION 6.01 Certificates for Stock. Every owner of stock of the
Corporation shall be entitled to have a certificate or certificates, to be in
such form as the Board shall prescribe, certifying the number and class of
shares of the stock of the Corporation owned by him. The certificates
representing shares of such stock shall be numbered in the order in which they
shall be issued and shall be signed in the name of the Corporation by the
President or a Vice President, and by the Secretary or an Assistant Secretary or
by the Chief Financial Officer or the Treasurer or an Assistant Treasurer. Any
of or all of the signatures on the certificates may be a facsimile. In case any
officer, transfer agent or registrar who has signed, or whose facsimile
signature has been placed upon, any such certificate, shall have ceased to be
such officer, transfer agent or registrar before such certificate is issued,
such certificate may nevertheless be issued by the Corporation with the same
effect as though the person who signed such certificate, or whose facsimile
signature shall have been placed thereupon, were such officer, transfer agent or
registrar at the date of issue. A record shall be kept of the respective names
of the persons, firms or corporations owning the stock represented by such
certificates, the number and class of shares represented by such certificates,
respectively, and the respective dates thereof, and in case of cancellation, the
respective dates of cancellation. Every certificate surrendered to the
Corporation for exchange or transfer shall be cancelled, and no new certificate
or certificates shall be issued in exchange for any existing certificate until
such existing certificate shall have been so cancelled, except in cases provided
for in Section 6.04.

               SECTION 6.02 Transfers of Stock. Transfers of shares of stock of
the Corporation shall be made only on the books of the Corporation by the
registered holder thereof, or by his attorney thereunto authorized by power of
attorney duly executed and filed with the Secretary, or with a transfer clerk or
a transfer agent appointed as provided in Section 6.03, and upon surrender of
the certificate or certificates for such shares properly endorsed and the
payment of all taxes thereon. The person in whose name shares of stock stand on
the books of the Corporation shall be deemed the owner thereof for all purposes
as regards the Corporation. Whenever any transfer of shares shall be made for
collateral security, and not absolutely, such fact shall be so expressed in the
entry of transfer if, when the certificate or certificates shall be presented to
the Corporation for transfer, both the transferor and the transferee request the
Corporation to do so.

               SECTION 6.03 Regulations. The Board may make such rules and
regulations as it may deem expedient, not inconsistent with these Bylaws,
concerning the issue, transfer and registration of certificates for shares of
the stock of the Corporation. It may appoint, or authorize any officer or
officers to appoint, one or more transfer clerks or one or more transfer 



                                       11
<PAGE>   12

agents and one or more registrars, and may require all certificates for stock to
bear the signature or signatures of any of them.

               SECTION 6.04 Lost, Stolen, Destroyed, and Mutilated Certificates.
In any case of loss, theft, destruction, or mutilation of any certificate of
stock, another may be issued in its place upon proof of such loss, theft,
destruction, or mutilation and upon the giving of a bond of indemnity to the
Corporation in such form and in such sum as the Board may direct; provided,
however, that a new certificate may be issued without requiring any bond when,
in the judgment of the Board, it is proper so to do.

               SECTION 6.05 Fixing Date for Determination of Stockholders of
Record. In order that the Corporation may determine the stockholders entitled to
notice of or to vote at any meeting of stockholders or any adjournment thereof,
or to express consent to corporate action in writing without a meeting, or
entitled to receive payment of any dividend or other distribution or allotment
of any rights, or entitled to exercise any rights in respect of any other
change, conversion or exchange of stock or for the purpose of any other lawful
action, the Board may fix, in advance, a record date, which shall not be more
than 60 nor less than 10 days before the date of such meeting, nor more than 60
days prior to any other action. If in any case involving the determination of
stockholders for any purpose other than notice of or voting at a meeting of
stockholders or expressing consent to corporate action without a meeting the
Board shall not fix such a record date, the record date for determining
stockholders for such purpose shall be the close of business on the day on which
the Board shall adopt the resolution relating thereto. A determination of
stockholders entitled to notice of or to vote at a meeting of stockholders shall
apply to any adjournment of such meeting; provided, however, that the Board may
fix a new record date for the adjourned meeting.

                                 INDEMNIFICATION

               SECTION 7.01 Action, Etc. Other Than by or in the Right of the
Corporation. The Corporation shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of the Corporation) by reason of the
fact that he is or was a director, officer, employee or agent of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the Corporation, and with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the Corporation, and, with 



                                       12
<PAGE>   13

respect to any criminal action or proceeding, that he had reasonable cause to
believe that his conduct was unlawful.

               SECTION 7.02 Actions, Etc., by or in the Right of the
Corporation. The Corporation shall indemnify any person who was or is a party or
is threatened to be made a party to any threatened, pending or completed action
or suit by or in the right of the Corporation to procure a judgment in its favor
by reason of the fact that he is or was a director, officer, employee or agent
of the Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorneys' fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Corporation, except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable for negligence or misconduct in the performance of his duty to the
Corporation unless and only to the extent that the Court of Chancery or the
court in which such action or suit was brought shall determine upon application
that, despite the adjudication of liability but in view of all the circumstances
of the case, such person is fairly and reasonably entitled to indemnity for such
expenses which the Court of Chancery or such other court shall deem proper.

               SECTION 7.03 Determination of Right of Indemnification. Unless
otherwise ordered by a court of competent jurisdiction, any indemnification
under Sections 7.01 or 7.02 of this Article VII shall be made by the Corporation
to any person who is or was a director, officer, employee or agent of the
Corporation, or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, unless a determination is reasonably and
promptly made, either (i) by the Board of Directors acting by a majority vote of
a quorum consisting of directors who were not a party to such action, suit or
proceeding, or (ii) if such a quorum is not obtainable, or, if obtainable, such
quorum so directs, by independent legal counsel in a written opinion, or (iii)
by the stockholders, that such person acted in bad faith and in a manner that
such person did not believe to be in or not opposed to the best interests of the
Corporation or, with respect to any criminal proceeding, that such person
believed or had reasonable cause to believe, that his or her conduct was
unlawful.

               SECTION 7.04 Indemnification Against Expenses of Successful
Party. Notwithstanding the other provisions of this Article, to the extent that
a director, officer, employee or agent of the Corporation has been successful on
the merits or otherwise in defense of any action, suit or proceeding referred to
in Section 7.01 or 7.02, or in defense of any claim, issue or matter therein, he
shall be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith.

               SECTION 7.05 Prepaid Expenses. Expenses incurred by an officer or
director in defending a civil or criminal action, suit or proceeding may be paid
by the Corporation in advance of the final disposition of such action, suit or
proceeding as authorized by the Board in the specific case upon receipt of an
undertaking by or on behalf of the director or officer to repay such amount
unless it shall ultimately be determined that he is entitled to be 


                                       13
<PAGE>   14

indemnified by the Corporation as authorized in this Article. Such expenses
incurred by other employees and agents may be so paid upon such terms and
conditions, if any, as the Board deems appropriate.

               SECTION 7.06 Other Rights and Remedies. The indemnification
provided by this Article shall not be deemed exclusive of any other rights to
which those seeking indemnification may be entitled under any Bylaws, agreement,
vote of stockholders or disinterested directors or otherwise, both as to action
in his official capacity and as to action in another capacity while holding such
office, and shall continue as to a person who has ceased to be a director,
officer, employee or agent and shall inure to the benefit of the heirs,
executors and administrators of such a person.

               SECTION 7.07 Insurance. Upon resolution passed by the Board, the
Corporation may purchase and maintain insurance on behalf of any person who is
or was a director, officer, employee or agent of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise against any liability asserted against him and incurred by him in any
such capacity, or arising out of his status as such, whether or not the
Corporation would have the power to indemnify him against such liability under
the provisions of this Article.

               SECTION 7.08 Constituent Corporations. For the purposes of this
Article, references to "the Corporation" include all constituent corporations
absorbed in a consolidation or merger as well as the resulting or surviving
corporation, so that any person who is or was a director, officer, employee or
agent of such a constituent corporation or is or was serving at the request of
such constituent corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise shall
stand in the same position under the provisions of this Article with respect to
the resulting or surviving corporation as he would if he had served the
resulting or surviving corporation in the same capacity.

               SECTION 7.09 Other Enterprises, Fines, and Serving at
Corporation's Request. For purposes of this Article, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on a person with respect to any employee
benefit plan; and references to "serving at the request of the Corporation"
shall include any service as a director, officer, employee or agent of the
Corporation which imposes duties on, or involves services by, such director,
officer, employee, or agent with respect to an employee benefit plan, its
participants, or beneficiaries; and a person who acted in good faith and in a
manner he reasonably believed to be in the interest of the participants and
beneficiaries of an employee benefit plan shall be deemed to have acted in a
manner "not opposed to the best interests of the Corporation" as referred to in
this Article.

                                  ARTICLE VIII

                                  MISCELLANEOUS

               SECTION 8.01 Seal. The Board may provide a corporate seal, which
shall be in the form of a circle and shall bear the name of the Corporation and
words and figures 



                                       14
<PAGE>   15

showing that the Corporation was incorporated in the State of Delaware and the
year of incorporation.

               SECTION 8.02 Waiver of Notices. Whenever notice is required to be
given by these Bylaws or the Certificate of Incorporation or by law, the person
entitled to said notice may waive such notice in writing, either before or after
the time stated therein, and such waiver shall be deemed equivalent to notice.

               SECTION 8.03 Amendments. These Bylaws, or any of them, may be
altered, amended or repealed, and new Bylaws may be made, (i) by the Board, by
vote of a majority of the number of directors then in office as directors,

majority of the shares entitled to vote thereon, provided that notice of such
proposed amendment, modification, repeal or adoption is given in the notice of
the stockholders' meeting. Any Bylaws made or altered by the stockholders may be
altered or repealed by either the Board or the stockholders. Notwithstanding the
foregoing, the affirmative vote of 80% of the total number of the then

for certain matters, recognizing the value to the Company of the efforts and
activities of Executive;

        NOW, THEREFORE, in consideration of foregoing recitals, the mutual
promises of the parties and the mutual benefits they will gain by the
performance thereof, and other good an valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties do hereby agree as
follows:

1. TERM OF EMPLOYMENT. The Company agrees to continue to employ Executive in his
current executive capacity, and Executive agrees to remain in the full-time
employ of the Company in such executive capacity and to perform his duties
provided herein, through February 28, 2002 (the period from the date hereof
through February 28, 2002, or such later date as this Agreement may be extended
in accordance with its provisions, being referred to herein as the "Term"),
unless earlier terminated pursuant to the provisions of this Agreement or upon
his earlier death. The Term shall automatically be extended for consecutive
one-year periods unless terminated by either party by written notice given at
least three (3) months prior to the expiration of the unextended initial term or
any subsequent one-year extension period.

2. AUTHORITY AND PERFORMANCE OF DUTIES. During the Term, the Company agrees to
employ Executive, and Executive agrees to serve, as the President and Chief
Executive Officer of the Company. At a minimum, Executive's duties,
responsibilities and authority will include all traditional duties,
responsibilities and authority of a President and Chief Executive Officer of a
corporation, and all duties, responsibilities and authority that Executive has
had prior to the date hereof. Without limiting the generality of the foregoing,
Executive's duties, responsibilities and authority shall include the authority
to hire, fire and discipline the workforce, set the terms and conditions of
work, and establish the compensation, benefits, bonuses and awards for the
Company's employees, all under the general policies and budget set forth by the
Board of Directors. Neither the Board of Directors nor any other person shall
interfere with Executive's day-to-day management of the Company's employees or
affairs. Executive agrees to devote his entire time and attention to the
business of the Company except insofar as he may be otherwise permitted by the
Board of Directors. The Company acknowledges Executive's residence and principal
place of performance of his duties in the State of Nevada. However, Executive
shall perform his duties at all such Company 




<PAGE>   2

offices and other locations as are reasonably necessary or appropriate to
fulfill his duties and functions as requested by the Company.

3. COMPENSATION AND BENEFITS.

        A. Salary. Executive shall receive for his services rendered hereunder
an annual base salary of Three Hundred Twenty Thousand Dollars ($320,000) (the
"Base Salary") payable on a monthly basis in twelve (12) equal monthly
installments, subject to standard withholdings for taxes and social security and
the like. Executive's compensation may be increased at any time by resolution of
the Board of Directors without the necessity of amending this Agreement or any
renewal thereof, and such increase shall not be deemed to be a change in the
terms or conditions of this Agreement.

        B. Bonus. During the Term, Executive may receive, at the discretion of
the Board of Directors, such annual or special bonuses as it may determine.

        C. Benefits. During the Term, Executive shall be entitled to participate
in any group insurance, hospitalization, medical, dental, health and accident,
disability or similar plan or program of the Company now existing or established
hereafter, to the extent that he is eligible under the general provisions
thereof. Notwithstanding the foregoing, Executive shall only be entitled to
participate in any such plan or program if executive officers of the Company are
generally eligible to participate in such plan or program. The Company may, in
its sole discretion and from time to time, establish additional senior
management benefit programs as it deems appropriate. Executive understands that
any such plans may be modified or eliminated in the discretion of the Company in
accordance with applicable law.

        D. Vacation. Executive shall be entitled to a period of annual paid
vacation time equal to not less than four (4) weeks per year. The days selected
for Executive's vacation shall be mutually agreeable to the Company and
Executive.

of the Board of Directors of the Company.

4. REASONABLE BUSINESS EXPENSES AND SUPPORT. Executive shall be reimbursed for
documented and reasonable business expenses in connection with the performance
of his duties hereunder and in accordance with the Company's general policies
relating thereto. Executive shall be furnished reasonable office space,
assistance and facilities.

5. TERMINATION OF EMPLOYMENT.

        A. Termination by the Company. This Agreement may be terminated by the
Company at any time with or without cause as set forth in this Agreement.

               (i) Without Cause. If, for any reason other than any "Certain
Event" (as defined below) during the Term, Executive's services hereunder shall
be terminated by the Company, he shall be entitled to receive, and the Company
shall pay to Executive, twelve (12)





                                       2
<PAGE>   3

months salary, which shall be paid in twelve (12) equal monthly installments
over the 12-month period following such termination. In addition, upon such
termination, Executive shall continue to be entitled to receive, for a period of
twelve (12) months following the date of termination, whatever other employee
benefits he was receiving at the time of such termination. The Company shall
also pay to Executive any salary earned but unpaid, and accrued but unused
vacation, as of the date of termination. Apart from the salary and benefit
continuation described in this subparagraph, Executive acknowledges that he is
entitled to no additional compensation in the event he is terminated without
cause. As used herein, a "Certain Event" means termination for "Cause" (as
hereinafter defined), Total and Permanent Disability (as hereinafter defined),
or death.

               (ii) For Cause. Notwithstanding the provisions of paragraph 1
hereof, the Company may at any time terminate Executive's employment hereunder
for cause. For purposes of this Agreement, the Company shall have "cause" to
terminate Executive's employment hereunder only upon (a) the continued use of
drugs or alcohol to the extent Executive becomes unable to substantially perform
his duties hereunder, (b) the engaging by Executive in willful misconduct that
is demonstrably and materially injurious to the Company, monetarily or
otherwise, (c) the commission by Executive or an act of fraud or embezzlement
against the Company, (d) the conviction of Executive of a felony involving moral
turpitude, or (e) the material breach by Executive of the provisions of
paragraphs 6 and 7 of this Agreement. Executive may not be terminated for cause
unless the Company first shall have given or delivered to Executive (i)
reasonable written notice setting forth the reasons for the Company's intention
to terminate for cause, and (ii) a notice of termination stating that in the
good faith opinion of the Board of Directors, Executive was guilty of conduct
set forth above in clauses (a), (b), (c), (d) or (e), and specifying the
particulars thereof in detail. In the event Executive is terminated for cause,
the Company shall pay to Executive any salary earned but unpaid, and accrued but
unused vacation as of the date of termination, and nothing more.

        B. Termination By Executive.

               (i) Voluntary Resignation. If at any time Executive wishes to
terminate his obligations under this Agreement, he shall give the Company at
least thirty (30) days notice. If Executive resigns his employment under this
subparagraph, the Company shall pay to Executive any salary earned but unpaid,
and accrued but unused vacation as of the last day worked by Executive, and
nothing more.

               (ii) Death Of Executive. In the event of the death of Executive
while employed under this Agreement, the Company shall pay to Executive's
designated beneficiary(s) as shown in the records of the Company any salary
earned but unpaid, and accrued but unused vacation as of the end of the month in
which Executive dies, and nothing more.

               (iii) Disability. For purposes hereof, "Total and Permanent
Disability" means inability to perform the services required hereunder due to
physical or mental disability that continues for 180 consecutive days or more,
or for an aggregate of 180 days in any period



                                       3

<PAGE>   4

of twelve months. Evidence of such disability shall be certified by a physician
acceptable to both the Company and Executive. In the event Executive's
employment is terminated as a result of his disability as defined herein, the
Company shall pay to Executive any salary earned but unpaid and accrued but
unused vacation as of the end of the month in which the termination for
disability occurs.

        C. Notice. Any notice required or permitted to be given under this
Agreement shall be in writing and shall be deemed to have been duly given or
delivered if delivered personally or mailed by registered or certified mail,
return receipt requested, with first class postage prepaid, to each of the
members of the Board of Directors in the case of the Company and to the
Executive at: Box 8343, Incline Village, Nevada 89451.

6. NON-COMPETITION. Executive agrees that, during the Term, he will not engage
or participate directly or indirectly in the conduct or management of any other
business that is similar to or in competition with the business of the Company
or its affiliates except as otherwise permitted by the Board of Directors.

7. DISCLOSURE OF INFORMATION. Executive recognizes and acknowledges that the
Company's confidential and proprietary information, as may exist from time to
time, are valuable, special and unique assets of the Company access to and
knowledge of which are essential to the performance of the duties of Executive
hereunder. Executive will not, during or after the Term in whole or in part,
disclose such confidential or proprietary information to any person, firm,
corporation or other entity for any reason or purpose whatsoever, nor shall
Executive make use of any such property for his own purposes for the benefit of
any person, firm, corporation or other entity (except the Company) under any
circumstances, during or after the Term, provided that after the Term these
restrictions shall not apply to such information which is then in the public
domain (provided that Executive was not responsible, directly or indirectly, for
such information entering the public domain without the Company's consent).

8. KEY MAN LIFE INSURANCE. Executive shall take such actions as may be
reasonably necessary or appropriate to permit the Company to obtain a key man
life insurance policy insuring Executive and naming the Company as beneficiary.
Notwithstanding the foregoing, for purposes of this Section 8, Executive shall
not be required to cease or be subject to restriction of his lawful activities
provided such activities would not be a basis for the Company's termination of
his employment for cause under this Agreement.

9. SUCCESSORS. This Agreement shall be binding upon the parties hereto, their
heirs, executors, administrators, successors and assigns. Executive, however,
shall not assign any part of his rights under this Agreement unless the Company
agrees thereto in writing. In event of a merger, consolidation or reorganization
involving the Company, this Agreement shall continue in force and become an
obligation of the Company's successor or successors.

10. ENTIRE AGREEMENT. This instrument contains the entire agreement of the
parties. It may not be changed orally but only by an agreement in writing signed
by the party against whom enforcement of any waiver, change, modification,
extension, or discharge is sought.

11. BINDING ARBITRATION. All disputes and differences which may arise out of or
in connection with this Agreement will be settled as far as possible by means of
negotiations




                                       4

<PAGE>   5

between the parties hereto. Except with regard to any disputes and differences
arising in connection with Paragraphs 6 and 7 of this Agreement, in which case
relief may be sought in any court of competent jurisdiction and proper venue,
such disputes and differences which are not settled by common accord are to be
resolved only by submission to binding arbitration to be conducted in San
Francisco, California in conformity with the Commercial Arbitration Rules of the
American Arbitration Association. The award of the arbitrator or arbitration
panel shall be final and binding on both parties hereto.

12. ATTORNEY FEES. If any legal proceeding is necessary to enforce or interpret
the terms of this Agreement, or to recover damages for breach therefor, the
prevailing party shall be entitled to reasonable attorney's fees, as well as
costs and disbursements, in addition to any other relief to which he or it may
be entitled.

13. CHOICE OF LAW. All questions concerning the construction, validity and
interpretation of this Agreement will be governed by the laws of the internal
law, and not the law of conflicts, of the State of Nevada.

                                                                    EXHIBIT 10.2



                              EMPLOYMENT AGREEMENT

        This EMPLOYMENT AGREEMENT (this "Agreement") is made as of the Effective
Date indicated below by and between CRL Network Services, Inc., a California
corporation ("CRL"), Integral Networking Corporation, a California corporation
("INTEGRAL NETWORKING") and Robert L. Ross("Employee").

                                   BACKGROUND

        This Agreement is entered into in connection with an Agreement and Plan
of Reorganization (the "Plan") dated as of December 21, 1998 by and among CRL,
RMS Sub Inc., a Delaware corporation, INTEGRAL NETWORKING, and certain
shareholders of INTEGRAL NETWORKING, pursuant to which CRL Acquisition Corp., a
wholly-owned subsidiary of CRL, is to merge with and into INTEGRAL NETWORKING.
The date on which the merger becomes effective will be the effective date of
this Agreement (the "Effective Date").

        Employee is a founder, principal shareholder and President of INTEGRAL
NETWORKING and has been actively involved in the development and marketing of
INTEGRAL NETWORKING's products. To preserve and protect the assets of INTEGRAL
NETWORKING, including INTEGRAL NETWORKING's goodwill, customers and trade
secrets of which Employee has and will have knowledge, and in consideration for
CRL entering into and performing under the Plan, Employee has agreed to enter
into this Agreement.

        NOW, THEREFORE, in consideration of the foregoing and the mutual
agreements of the parties contained herein, CRL and Employee hereby agree as
follows:

        1. Employment. CRL will employ Employee and Employee accepts employment
with CRL for a period of two years from the Effective Date (the "Initial
Period"), unless Employee's employment is sooner terminated in accordance with
this Agreement. Employee's employment may continue after this Initial Period but
will then be terminable by either party at will, with or without cause. The
obligations of CRL and Employee set forth in the Proprietary Information and
Inventions Agreement (as defined in Section 7) (referring to confidentiality),
and in Section 8 (referring to termination), and in Section 9(i) (referring to
dispute resolution) and, to the extent specifically provided therein, the
obligations of CRL and Employee set forth in Section 5 (referring to employee
benefits) and Section 6 (referring to reimbursement of expenses), will survive
the termination of Employee's employment, regardless of cause.

        2. Duties. Employee will be employed as a full-time employee of CRL and
will serve as President, Integral Networking Corporation, a CRL Company
responsible for INTEGRAL NETWORKING operations, reporting to Jim Couch,
President of CRL or his delegate. Employee agrees that, to the best of his
ability and experience, he will at all times conscientiously perform all of the
duties and obligations assigned to him under this Agreement. At CRL's option, it
will be entitled to reasonable use of Employee's name in promotional,
advertising and other materials used in the ordinary course of business.



<PAGE>   2

        3. Full-time Employment. Employee's employment will be on a full-time
basis, in accordance with standard employee policies for CRL. Employee will sign
a standard CRL employment agreement. Employee will not engage in any other
business or render any commercial or professional services, directly or
indirectly, to any other person or organization, whether for compensation or
otherwise, provided that Employee may (i) provide incidental assistance to
family members on matters of family business; and (ii) sit on the boards of
charitable and nonprofit organizations or other companies which do not, at the
time of Employee's appointment or election, to Employee's knowledge, compete
with CRL; provided in each case that such activities do not conflict with or
interfere with Employee's obligations to CRL. Employee may make personal
investments in non-publicly traded corporations, partnerships or other entities,
which, to the knowledge of Employee, do not at the time of such investment
design, research, distribute or otherwise market products similar to or
competitive with CRL in the customer relationship management system for the
financial services industry software product market. Employee may make personal
investments in publicly traded corporations regardless of the business they are
engaged in, provided that Employee does not at any time own in excess of 1% of
the issued and outstanding stock of any such corporation.

        4. Salary. Employee's salary for the period commencing on the Effective
Date will be no less than $56,500 per year, payable on CRL's regular payroll
dates, less required withholdings and will be eligible for a target bonus of
$100,000 based on targeted personal and company performance.

        5. Employee Benefits. Employee will be entitled to insurance, vacation
and other benefits commensurate with other executive officers of CRL. Employee
has received a summary of CRL's standard employee benefits policies in effect as
of the date hereof.

        6. Reimbursement of Business Expenses. CRL will, in accordance with
CRL's policies in effect from time to time, reimburse Employee for all
reasonable business expenses incurred by Employee in connection with the
performance of his duties under this Agreement, including, without limitation,
reasonable expenditures for office space, supplies, equipment and expenses and
for business entertainment and travel, upon submission of the required
documentation required pursuant to CRL's standard policies and record keeping
procedures.

        7. Confidentiality. Simultaneously with the execution of this Agreement,
Employee is executing and delivering and hereby adopts and agrees to be bound by
CRL's standard Employee Proprietary Information and Inventions Agreement, a copy
of which is attached to this Agreement as Exhibit A (the "Proprietary
Information and Inventions Agreement").

        8. Termination.

               (a) By CRL. CRL may terminate Employee's employment at any time
with or without cause upon written notice to Employee.

               (b) By Employee. Employee may terminate Employee's employment in
the event that CRL is in material breach of this Agreement upon written notice
to CRL, provided that such termination will become effective only upon the
expiration of 30 days following such notice 




                                       2
<PAGE>   3

and then only if the alleged breach remains uncured. Such termination shall be
deemed a termination by CRL of Employee's employment under Section 8(a) for
which Employee shall have the remedy set forth in Section 8(d).

               (c) If Employee resigns or otherwise terminates Employee's
employment without cause, Employee shall receive no Termination Payments
(defined below).

               (d) If CRL terminates Employee For Cause (as defined below), this
Agreement shall terminate and Employee shall not be entitled to any further
benefits hereunder, except as specifically set forth herein. If, during the
Initial Period, CRL terminates Employee and such termination is not For Cause,
CRL will pay to Employee, for the lesser of three months or the remainder of the
Initial period, on a monthly basis an amount equal to Employee's monthly salary
at the monthly rate paid to Employee immediately prior to such termination (the
"Termination Payments"). CRL's obligation to make these Termination Payments
pursuant to this Section 8(d) is in lieu of any damages or any other payment
which CRL might otherwise be obligated to pay Employee as a result of Employee's
termination of employment. CRL and Employee agree that, in view of the nature of
the issues likely to arise in the event of such a termination, it would be
impracticable or extremely difficult to fix the actual damages resulting from
such termination and proving actual damages, causation and foreseeability in the
case of such termination would be costly, inconvenient and difficult. In
requiring CRL to make the Termination Payments as set forth herein, it is the
intent of the parties to provide, as of the date of this Agreement, for a
liquidated amount of damages to be paid by CRL to Employee. Such liquidated
amount shall be deemed full and adequate damages for such termination and is not
intended by either party to be a penalty. For purposes of this Agreement, "For
Cause" shall mean:

                      (i) Employee's continued failure to perform his duties
hereunder in good faith, after written notice of such failure from CRL or
INTEGRAL NETWORKING to Employee and an opportunity to cure such failure to
perform;

                      (ii) Employee engaging in knowing and intentional illegal
conduct which is injurious to CRL or INTEGRAL NETWORKING or their affiliates;

                      (iii) Employee being convicted of a felony or committing
an act of dishonesty or fraud against, or the misappropriation of property
belonging to, CRL or INTEGRAL NETWORKING or their affiliates;

                      (iv) Employee breaching in any material respect the terms
of this Agreement or the Noncompetition Agreement;

                      (v) Employee's commencement of employment with another
employer while an employee of CRL or INTEGRAL NETWORKING; and

                      (vi) Any behavior or breach of CRL's standards of business
conduct which would be cause for termination under CRL's employment policies as
they currently exist or




                                       3
<PAGE>   4

as effected in the future, after written notice of such behavior or breach from
CRL or INTEGRAL NETWORKING to Employee and an opportunity to cure such behavior
or breach.

               (e) Upon Death. If Employee dies during the term of this
Agreement, CRL will pay his estate an amount equal to all salary, bonuses and
benefits accrued as of the date of his death.

        9. Miscellaneous.

               (a) Notices. Any and all notices permitted or required to be

or (iii) on the third business day after having been sent by registered or

Employee's employment. This Agreement may not be changed or modified in whole or
in part except by a writing signed by the party against whom enforcement of the
change or modification is sought.

               (c) Successors and Assigns. This Agreement will not be assignable
by either Employee or CRL, except that the rights and obligations of CRL under
this Agreement may be assigned to a corporation which becomes the successor to
CRL as the result of a merger or other corporate reorganization and which
continues the business of CRL, or any other subsidiary of CRL, provided that CRL
guarantees the performance by such assignee of CRL's obligations hereunder.

               (d) Governing Law. This Agreement will be governed by and
interpreted according to the substantive laws of the State of California without
regard to such state's conflicts law.

               (e) No Waiver. The failure of either party to insist on strict
compliance with any of the terms of this Agreement in any instance or instances
will not be deemed to be a waiver of any term of this Agreement or of that
party's right to require strict compliance with the terms of this Agreement in
any other instance.

               (f) Severability. Employee and CRL recognize that the limitations
contained herein are reasonably and properly required for the adequate
protection of the interests of CRL. If for any reason a court of competent
jurisdiction or binding arbitration proceeding finds any provision of this
Agreement, or the application thereof to be unenforceable, the remaining
provisions of this Agreement will be interpreted so as best to reasonably effect
the intent of the parties. The parties further agree to replace any such invalid
or unenforceable provisions with valid and enforceable provisions designed to
achieve, to the extent possible, the business purposes and intent of such
unenforceable provisions.

               (g) Counterparts. This Agreement may be executed in counterparts
which when taken together will constitute one instrument. Any copy of this
Agreement with the original signatures of all parties appended will constitute
an original.

               (h) Effect of Agreement. This Agreement will be void and have no
effect if the Effective Date does not occur on or before January 31, 1999.

               (i) Dispute Resolution.

                      (i) Arbitration of Disputes. Any dispute under this
Agreement shall be resolved by arbitration in San Francisco, California and,
except as herein specifically stated, in accordance with the commercial
arbitration rules of the American Arbitration Association ("AAA Rules") then in
effect. However, in all events, these arbitration provisions shall govern over
any conflicting rules which may now or hereafter be contained in the AAA Rules.
Any judgment upon the award rendered by the arbitrator may be entered in any
court having jurisdiction over the subject matter thereof The arbitrator shall
have the authority to grant any equitable and legal remedies that would be
available in any judicial proceeding instituted to resolve such dispute; except
that the arbitrator shall not grant any punitive, consequential or incidental
damages.

<PAGE>   6



                      (ii) Compensation of Arbitrator. Any such arbitration will
be conducted before a single arbitrator who will be compensated for his or her
services at a rate to be determined by the parties or by the American
Arbitration Association, but based upon reasonable hourly or daily consulting
rates for the arbitrator in the event the parties are not able to agree upon his
or her rate of compensation.

                      (iii) Selection of Arbitrator. The American Arbitration
Association will have the authority to select an arbitrator from a list of
arbitrators who are partners in a nationally recognized firm of independent
certified public accountants from the management advisory services department
(or comparable department or group) of such firm; provided, however, that such
firm cannot be the firm of certified public accountants then auditing the books
and records of either party or providing management or advisory services for
either party.

                      (iv) Payment of Costs. CRL and Employee will each pay 50%
of the initial compensation to be paid to the arbitrator in any such arbitration
and 50% of the costs of transcripts and other normal and regular expenses of the
arbitration proceedings; provided, however, that the prevailing party in any
arbitration will be entitled to an award of attorneys' fees and costs, and all
costs of arbitration, other than those provided for above, will be paid by the
losing party, and the arbitrator will be authorized to make such determinations.

                      (v) Burden of Proof. For any dispute submitted to
arbitration, the burden of proof will be as it would be if the claim were
litigated in a judicial proceeding.

                      (vi) Award. Upon the conclusion of any arbitration
proceedings hereunder, the arbitrator will render findings of fact and
conclusions of law and a written opinion setting forth the basis and reasons for
any decision reached and will deliver such documents to each party to this
Agreement along with a signed copy of the award.

                      (vii) Terms of Arbitration. The arbitrator chosen in
accordance with these provisions will not have the power to alter, amend or
otherwise affect the terms of these arbitration provisions or the provisions of
this Agreement.

                      (viii) Exclusive Remedy. Except as specifically otherwise
provided in this Agreement, arbitration will be the sole and exclusive remedy of

                           CRL NETWORK SERVICES, INC.

                           1997 EQUITY INCENTIVE PLAN

                            As Adopted August 8, 1997



        1. PURPOSE. The purpose of the Plan is to provide incentives to attract,
retain and motivate eligible persons whose present and potential contributions
are important to the success of the Company, its Parent, Subsidiaries and
Affiliates, by offering them an opportunity to participate in the Company's
future performance through awards of Options, Restricted Stock and Stock
Bonuses. Capitalized terms not defined in the text are defined in Section 22.

        2. SHARES SUBJECT TO THE PLAN.

               2.1 Number of Shares Available. Subject to Sections 2.2 and 18,
the total number of Shares reserved and available for grant and issuance
pursuant to the Plan shall not exceed ten percent (10%) of the Company's
authorized common stock ("Shares"). Subject to Sections 2.2 and 18, Shares shall
again be available for grant and issuance in connection with future Awards under
the Plan that: (a) are subject to issuance upon exercise of an Option but cease
to be subject to such Option for any reason other than exercise of such Option,
(b) are subject to an Award granted hereunder but are forfeited or are
repurchased by the Company at the original issue price, or (c) are subject to an
Award that otherwise terminates without Shares being issued.

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

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

                      (b)    prescribe, amend and rescind rules and regulations
                             relating to the Plan;

                      (f)    determine whether Awards will be granted singly, in
                             combination, in tandem with, in replacement of, or
                             as alternatives to, other Awards under the Plan or
                             any other incentive or compensation plan of the
                             Company or any Parent, Subsidiary or Affiliate of

                      (j)    determine whether an Award has been earned; and

                      (k)    make all other determinations necessary or
                             advisable for the administration of the Plan.

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

               4.3 Exchange Act Requirements. If the Company is subject to the
Exchange Act, the Company will take appropriate steps to comply with the
disinterested director requirements of Section 16(b) of the Exchange Act,
including but not limited to, the appointment by the Board of a Committee
consisting of not less than two persons (who are members of the Board), each of
whom is a Disinterested Person.

        5. OPTIONS. The Committee may grant Options to eligible persons and
shall determine whether such Options shall be incentive stock options within the
meaning of the Code ("ISOs") or nonqualified stock options ("NQSOs"), the number
of Shares subject to the Option, the Exercise Price of the Option, the period
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

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

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

               5.3 Exercise Period. Options shall be exercisable within the
times or upon the events determined by the Committee as set forth in the Stock
Option Agreement, provided, however, that no Option shall be exercisable after
the expiration of ten (10) years from the date the Option is granted, and
provided further that no Option granted to a person who directly or by
attribution owns more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or any Parent or Subsidiary of the
Company ("Ten Percent Shareholder") shall be exercisable after the expiration of
five (5) years from the date the Option is granted. The Committee also may
provide for the Options to become exercisable at one time or from time to time,
periodically or otherwise, in such number or percentage of the Shares as the
Committee determines. Options which provide for the attainment of certain
performance goals or criteria set forth in the Stock Option Agreement as a
condition to the exercisability of all or a portion of the shares granted
thereunder shall only be granted to key employees, executive managers and sales
personnel of the Company who are able to materially affect the attainment of
such goals.

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




                                       3
<PAGE>   4

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

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

                      (a)    If the Participant is Terminated for any reason
                             except death or Disability, then Participant may
                             exercise such Participant's Options only to the
                             extent that such Options would have been
                             exercisable upon the Termination Date no later than
                             three (3) months after the Termination Date (or
                             such shorter time period as may be specified in the
                             Stock Option Agreement), but in any event, no later
                             than the expiration date of the Options.

                      (b)    If the Participant is terminated because of death
                             or Disability (or the Participant dies within three
                             months of such termination), then Participant's
                             Options may be exercised only to the extent that
                             such Options would have been exercisable by
                             Participant on the Termination Date and must be
                             exercised by Participant (or Participant's legal
                             representative or authorized assignee) no later
                             than twelve (12) months after the Termination Date
                             (or such shorter time period as may be specified in
                             the Stock Option Agreement), but in any event no
                             later than the expiration date of the Options.

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

               5.8 Limitations on ISOs. The aggregate Fair Market Value
(determined as of the date of grant) of Shares with respect to which ISOs are
exercisable for the first time by a Participant during any calendar year (under
the Plan or under any other incentive stock option plan of the Company or any
Affiliate, Parent or Subsidiary of the Company) shall not exceed $100,000. If
the Fair Market Value of Shares on the date of grant with respect to which ISOs
are exercisable for the first time by a Participant during any calendar year
exceeds $100,000, the Options for the first $100,000 worth of Shares to become
exercisable in such calendar year shall be ISOs and the Options for the amount
in excess of $100,000 that become exercisable in that calendar year shall be
NQSOs. In the event that the Code or the regulations promulgated



                                       4
<PAGE>   5

thereunder are amended after the Effective Date of the Plan to provide for a
different limit on the Fair Market Value of Shares permitted to be subject to
ISOs, such different limit shall be automatically incorporated herein and shall
apply to any Options granted after the effective date of such amendment.

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

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

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

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

               6.2 Purchase Price. The Purchase Price of Shares sold pursuant to
a Restricted Stock Award shall be determined by the Committee and shall be at
least 85% of the Fair Market value of the Shares on the date the Restricted
Stock Award is granted, except in the case of a sale to a Ten Percent
Shareholder, in which case the Purchase Price shall be 100% of the Fair Market
Value. Payment of the Purchase Price may be made in accordance with Section 8 of
the Plan.




                                       5
<PAGE>   6

               6.3 Restrictions. Restricted Stock Awards shall be subject to
such restrictions as the Committee may impose. The Committee may provide for the
lapse of such restrictions in installments and may accelerate or waive such
restrictions, in whole or part, based on length of service, performance or such
other factors or criteria as the Committee may determine.

        7. STOCK BONUSES.

               7.1 Awards of Stock. A stock Bonus is an award of Shares (which
may consist of Restricted Stock) for services rendered to the Company or any
Parent, Subsidiary or Affiliate of the Company. A Stock Bonus may be awarded for
past services already rendered to the Company, or any Parent, Subsidiary or
Affiliate of the Company pursuant to an Award Agreement (the "Stock Bonus
Agreement") that shall be in such form (which need not be the same for each
Participant) as the Committee shall from time to time approve, and shall comply
with and be subject to the terms and conditions of the Plan. A Stock Bonus may
be awarded upon satisfaction of such performance goals as are set out in advance
(a "Performance Stock Bonus") in Participant's individual Award Agreement (the
"Performance Stock Bonus Agreement") that shall be in such form (which need not
be the same for each Participant) as the Committee shall from time to time
approve, and shall comply with and be subject to the terms and conditions of the
Plan. Stock Bonuses may vary from Participant to Participant and between groups
of Participants, and may be based upon the achievement of the Company, Parent,
Subsidiary or Affiliate and/or individual performance factors or upon such other
criteria as the Committee may determine. Performance Stock Bonuses shall only be
granted to executive managers of the Company who are, in the scope of their
employment, able to materially affect the attainment of any performance goals
set forth in the Performance Stock Bonus Agreement.

               7.2 Terms of Stock Bonuses. The Committee shall determine the
number of Shares to be awarded to the Participant and whether such Shares shall
be Restricted Stock. If the Stock Bonus is being earned upon the satisfaction of
performance goals pursuant to a Performance Stock Bonus Agreement, then the
Committee shall determine: (a) the nature, length and starting date of any
period during which performance is to be measured (the "Performance Period") for
each Stock Bonus; (b) the performance goals and criteria to be used to measure
the performance, if any; (c) the number of Shares that may be awarded to the
Participant; and (d) the extent to which such Stock Bonuses have been earned.
Performance Periods may overlap and Participants may participate simultaneously
with respect to Stock Bonuses that are subject to different Performance Periods
and different performance goals and other criteria. The number of Shares may be
fixed or may vary in accordance with such performance goals and criteria as may
be determined by the Committee. The Committee may adjust the performance goals
applicable to the Stock Bonuses to take into account changes in law and
accounting or tax rules and to make such adjustments as the Committee deems
necessary or appropriate to reflect the impact of extraordinary or unusual
items, events or circumstances to avoid windfalls or hardships.

               7.3 Form of Payment. The earned portion of a Stock Bonus may be
paid currently or on a deferred basis with such interest or dividend equivalent,
if any, as the Committee may determine. Payment may be made in the form of cash,
whole Shares, including



                                       6
<PAGE>   7


Restricted Stock, or a combination thereof, either in a lump sum payment or in
installments, all as the Committee shall determine.

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

        8. PAYMENT FOR SHARE PURCHASES.

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

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

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

                      (c)    by tender of a full recourse promissory note having
                             such terms as may be approved by the Committee and
                             bearing interest at a rate sufficient to avoid
                             imputation of income under Sections 483 and 1274 of
                             the Code; provided, however, that Participants who
                             are not employees of the Company shall not be
                             entitled to purchase Shares with a promissory note
                             unless the note is adequately secured by collateral
                             other than the Shares; provided, further that the
                             portion of the Purchase Price equal to the par
                             value of the Shares, if any, must be paid in cash;

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

                      (e)    by tender of property;

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

                             (1)    through a "same day sale" commitment from
                                    Participant and a broker-dealer that is a

                                    so purchased to pay for the Exercise Price,
                                    and whereby the NASD Dealer irrevocably
                                    commits upon receipt of such Shares to
                                    forward the Exercise Price directly to the
                                    Company; or

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

                      or

                      (g) by any combination of the foregoing.

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

        9. WITHHOLDING TAXES.

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

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

                      (a)    the election must be made on or prior to the
                             applicable Tax Date,

                      (b)    once made, then except as provided below, the
                             election shall be irrevocable as to the particular
                             Shares as to which the election is made;



                                       8
<PAGE>   9

                      (c)    all elections shall be subject to the consent or
                             disapproval of the Committee;

                      (d)    if the Participant is an Insider and if the Company
                             is subject to Section 16(b) of the Exchange Act:
                             (1) the election may not be made within six (6)
                             months of the date of grant of the Award, except as
                             otherwise permitted by SEC Rule 16b-3(e) under the
                             Exchange Act, and (2) either (A) the election to
                             use stock withholding must be irrevocably made at
                             least six (6) months prior to the Tax Date
                             (although such election may be revoked at any time
                             at least six (6) month prior to the Tax Date) or
                             (B) the exercise of the Option or election to use
                             stock withholding must be made in the ten (10) day
                             period beginning on the third day following the
                             release of the Company's quarterly or annual
                             summary statement of sales or earnings; and

                      (e)    in the event that the Tax Date is deferred until
                             six (6) months after the delivery of Shares under
                             Section 83(b) of the Code, the Participant shall
                             receive the full number of Shares with respect to
                             which the exercise occurs, but such Participant
                             shall be unconditionally obligated to tender back
                             to the Company the proper number of Shares on the
                             Tax Date.

        10. PRIVILEGES OF STOCK OWNERSHIP.

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

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

        11. TRANSFERABILITY. Awards granted under the Plan, and any interest
therein, shall not be transferable or assignable by Participant, and may not be
made subject to execution, attachment or similar process, otherwise than by will
or by the laws of descent and distribution or as



                                       9
<PAGE>   10

consistent with the specific Plan and Award Agreement provisions relating
thereto. During the lifetime of the Participant an Award shall be exercisable
only by the Participant, and any elections with respect to an Award may be made
only by the Participant.

        12. RESTRICTIONS ON SHARES. At the discretion of the Committee, the
Company may reserve to itself and/or its assignee(s) in the Award Agreement (a)
a right of first refusal to purchase all Shares that a Participant (or a
subsequent transferee) may propose to transfer to a third party, and/or (b) a
right to repurchase a portion of or all Shares held by a Participant following
such Participant's Termination at any time within ninety (90) days after the
later of Participant's Termination Date and the date Participant purchases
Shares under the Plan, for cash or cancellation of purchase money indebtedness,
at: (A) with respect to Shares that are "Vested" (as defined in the Award
Agreement), the higher of: (1) Participant's original Purchase Price, or (2) the
Fair Market Value of such Shares on Participant's Termination Date, provided,
such right of repurchase terminates when the Company's securities become
publicly traded; or (B) with respect to Shares that are not "Vested" (as defined
in the Award Agreement), at the Participant's original Purchase Price, provided,
that the right to repurchase at the original Purchase Price lapses at the rate
of at least 20% per year over 5 years from the date the Shares were purchased,
and if the right to repurchase is assignable, the assignee must pay the Company,
upon assignment of the right to repurchase, cash equal to the excess of the Fair
Market Value of the Shares over the original Purchase Price.

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

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




                                       10

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

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

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

        18 CORPORATE TRANSACTIONS.

               18.1 Assumption or Replacement of Awards by Successor. In the
event of (a) a merger or consolidation in which the Company is not the surviving
corporation (other than a merger or consolidation with a wholly-owned
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the shareholders of
the Company and the Awards granted under the Plan are assumed or replaced by the
successor corporation, which assumption shall be binding on all Participants),
(b) a dissolution or liquidation of the Company, (c) the sale of substantially
all of the assets of the Company, or (d) any other transaction which qualifies
as a "corporate action" under Section 424(a) of the Code wherein the
shareholders of the Company give up all of their equity interest in the Company
(except for the acquisition, sale or transfer of all or substantially all of the
outstanding shares of the Company) (any or all of the events described in (a)
through (d) above constituting a "Change in Control"), any or all outstanding
Awards may be assumed or replaced by the successor corporation (if any), which
assumption or replacement shall be binding on all Participants. In the
alternative, the successor corporation may substitute equivalent



                                       11
<PAGE>   12

Awards or provide substantially similar consideration to Participants as was
provided to shareholders (after taking into account the existing provisions of
the Awards). The successor corporation may also issue, in place of outstanding
Shares of the Company held by the Participant, substantially similar shares or
other property subject to repurchase restrictions no less favorable to the
Participant.

        In the event such successor corporation (if any) refuses to assume or
substitute Options, as provided above, pursuant to a transaction described in
this Subsection 18.1, such Options shall expire upon the happening of such
transaction at such time and on such conditions as the Board shall determine.

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

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

               18.4 Additional Vesting of Options. In the event of a Change in
Control, the vesting schedule in each Stock Option Agreement for Options granted
pursuant to this Plan shall automatically be modified so that, as of the date a
Change in Control occurs, the number of Options vested and exercisable by each
Option Holder shall be increased to such number the Option holder would
otherwise be entitled to exercise if the Option holder remained an employee of
the Company one year from the date of the Change in Control.

        19. ADOPTION AND SHAREHOLDER APPROVAL. The Plan shall become effective
on the date that it is adopted by the Board (the "Effective Date"), The Plan
shall be approved by the shareholders of the Company (excluding Shares issued
pursuant to this Plan), consistent with applicable laws, within twelve months
before or after the Effective Date. Upon the Effective Date, the Board may grant
Awards pursuant to the Plan, provided, however, that: (a) no Option may be
exercised prior to initial shareholder approval of the Plan; (b) no Option




                                       12
<PAGE>   13

granted pursuant to an increase in the number of Shares approved by the Board
shall be exercised prior to the time such increase has been approved by the
shareholders of the Company; and (c) in the event that shareholder approval is
not obtained within the time period provided herein, all Awards granted
hereunder shall be canceled, any Shares issued pursuant to any Award shall be
canceled and any purchase of Shares hereunder shall be rescinded. After the
Company becomes subject to Section 16(b) of the Exchange Act, the Company will
comply with the requirements of Rule 16b-3 (or its successor), as amended, with
respect to shareholder approval.

        20. TERM OF PLAN. The Plan will terminate ten (10) years from the
Effective Date or, if earlier, the date of shareholder approval.

        21. AMENDMENT OR TERMINATION OF PLAN. The Board may at any time
terminate or amend the Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to the Plan; provided, however, that the Board shall not, without the approval
of the shareholders of the Company, amend the Plan in any manner that requires

thereunder as such provisions apply to ISO plans or pursuant to the Exchange Act

and further align their interest with those of the stockholders of the Company
by providing for or increasing the proprietary interest of such directors in the
Company.

SECTION 2.  PERSONS ELIGIBLE UNDER PLAN

               Any person, including any director of the Company, who is an
officer or employee of or consultant to the Company or any of its subsidiaries
(an "Employee") and any director of the Company who is not an Employee (a
"Nonemployee Director") shall be eligible to be considered for the grant of
Awards (as defined herein); provided that only persons who are employees of the
Company shall be eligible to be considered for the grant of "Incentive Stock
Options" (as defined herein).

SECTION 3.  AWARDS

               (a) The Board of Directors or the Committee (as hereinafter
defined), on behalf of the Company, is authorized under this Plan to enter into
any type of arrangement with an Employee or a Nonemployee Director that is not
inconsistent with the provisions of this Plan and that, by its terms, involves
or might involve the issuance of (i) shares of Common Stock, par value $.01 per
share, of the Company (collectively "Common Shares"), or (ii) a right or
interest with an exercise or conversion privilege at a price related to the
Common Shares or with a value derived from the value of the Common Shares, which
right or interest may, but need not, constitute a Derivative Security (as such
term is defined in Rule 16a-1 promulgated under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), as such rule may be amended from time to
time). The entering into of any such arrangement is referred to herein as the
"grant" of an "Award."

               (b) Common Shares may be issued pursuant to an Award for any
lawful consideration as determined by the Committee, including, without
limitation, services rendered by the recipient of such Award.

               (c) Awards are not restricted to any specified form or structure

rights to acquire stock, securities convertible into or redeemable for stock,
stock appreciation rights, limited stock appreciation rights, phantom stock,
dividend equivalents, performance units or performance shares, and an Award may

the alternative.

               (d) Subject to the provisions of this Plan, the Committee, in its
sole and absolute discretion, shall determine all of the terms and conditions of
each Award granted under this Plan, which terms and conditions may include,
among other things:

                      (i) a provision permitting the recipient of such Award,
        including any recipient who is a director or officer of the Company, to
        pay the purchase price of the Common Shares or other property issuable
        pursuant to such Award, and/or such recipient's tax withholding
        obligation with respect to such issuance, in whole or in part, by any
        one or more of the following:

                             (A) the delivery of cash or a promissory note, the
               terms and conditions of which shall be determined by the
               Committee,

                             (B) the delivery of previously owned shares of
               capital stock of the Company (including "pyramiding") or other
               property deemed acceptable by the Committee, provided that the
               Company is not then prohibited from purchasing or acquiring
               shares of its capital stock or such other property,

                             (C) a reduction in the amount of Common Shares or
               other property otherwise issuable pursuant to such Award, or

                             (D) any other lawful consideration deemed
               acceptable by the Committee.

                      (ii) a provision specifying the exercise or settlement
        price for any option, stock appreciation right or similar Award, or
        specifying the method by which such price is determined; provided, that,
        if the Company is subject to the reporting requirements of the Exchange
        Act, the exercise or settlement price of any option, stock appreciation
        right or similar Award that is intended to qualify as performance based
        compensation ("Performance Based Compensation") for purposes of Section
        162(m) of the Internal Revenue Code of 1986, as amended (the "Code"),
        shall be not less than the fair market value of a Common Share on the
        date such Award is granted;

                      (iii) a provision relating to the exercisability and/or

        termination, expiration and/or forfeiture of Awards;




                                       2
<PAGE>   3

                      (iv) a provision conditioning or accelerating the receipt
        of benefits pursuant to such Award, either automatically or in the
        discretion of the Committee, upon the occurrence of specified events,
        including, without limitation, a change of control of the Company (as
        defined by the Committee), an acquisition of a specified percentage of
        the voting power of the Company, the dissolution or liquidation of the
        Company, a sale of substantially all of the property and assets of the
        Company or an event of the type described in Section 8 hereof; and/or

                      (v) any provisions required in order for such Award to
        qualify as an incentive stock option (an "Incentive Stock Option") under
        Section 422 of the Code, provided that the recipient of such Award is
        eligible under the Code to receive an Incentive Stock Option, and, if
        the Company is subject to the reporting requirements of the Exchange
        Act, any provisions required in order for such Award to qualify (A) as
        Performance Based Compensation and/or (B) for an exemption from Section
        16 of the Exchange Act.

               (e) Notwithstanding any other provision of this Plan, no Employee
shall be granted Awards for in excess of ________ shares of Common Stock and no
Nonemployee Director shall be granted Awards in excess of _______ shares of
Common Stock during any one calendar year. The limitation set forth in this
Section 3(d) shall be subject to adjustment as provided in Section 8 hereof, but
only to the extent such adjustment would not affect the status of compensation
attributable to Awards hereunder as Performance-Based Compensation.

SECTION 4.  GRANTS TO NON-EMPLOYEE DIRECTORS

               (a) Each non-employee director of the Company shall receive an
option to purchase a minimum of a number of shares of Common Stock upon such
director's appointment to the Board of Directors as is determined by resolution
of the Board of Directors. The terms and conditions of such award shall be
determined by the Committee.

               (b) On the date of the Company's next annual meeting of
stockholders, and each subsequent year thereafter, each non-employee director
who has been re-elected as director shall receive an option to purchase
15,000 shares of Common Stock. The terms and conditions of such award shall
be determined by the Committee.

               (c) In its discretion, the Committee may increase the number of
shares purchasable upon exercise of such option for any director individually,
provided that the total number of shares purchasable upon exercise of all
options granted to any non-employee director in any year shall not be greater
than _____________ shares.

SECTION 5.  STOCK SUBJECT TO PLAN

               (a) The aggregate number of Common Shares that may be issued
pursuant to all Incentive Stock Options granted under this Plan shall not exceed
3,000,000, subject to adjustment as provided in Section 8 hereof.






                                       3
<PAGE>   4


               (b) The aggregate number of Common Shares issued and issuable
pursuant to all Awards (including Incentive Stock Options) granted under this
Plan shall not exceed 3,000,000, subject to adjustment as provided in Section
8 hereof.

               (c) For purposes of Section 5(b) hereof, the aggregate number of
Common Shares issued and issuable pursuant to all Awards granted under this Plan
shall at any time be deemed to be equal to the sum of the following:

                      (i) the number of Common Shares that were issued prior to
        such time pursuant to Awards granted under this Plan, other than Common
        Shares that were subsequently reacquired by the Company pursuant to the
        terms and conditions of such Awards and with respect to which the holder
        thereof received no benefits of ownership such as dividends; plus

                      (ii) the number of Common Shares that were otherwise
        issuable prior to such time pursuant to Awards granted under this Plan,
        but that were withheld by the Company as payment of the purchase price
        of the Common Shares issued pursuant to such Awards or as payment of the
        recipient's tax withholding obligation with respect to such issuance;
        plus

                      (iii) the maximum number of Common Shares issuable at or
        after such time pursuant to Awards granted under this Plan prior to such
        time.

               (d) The "Fair Market Value" of a Common Share or other security
on any date (the "Determination Date") shall be determined as follows:

                      (i) If the Common Shares are not publicly traded on the
        business day immediately preceding the Determination Date, then Fair
        Market Value shall equal the price at which one could reasonably expect
        such Common Shares to be sold in an arm's length transaction, for cash,
        other than on an installment basis, to a person not employed by,
        controlled by, in control of or under common control with the issuer of
        such Common Shares. Such Fair Market Value shall be that which has
        currently or most recently been determined for this purpose by the Board
        or at the discretion of the Board, by an independent appraiser or
        appraisers selected by the Board, in either case giving due
        consideration to recent transactions involving shares of such Common
        Shares, if any, the Company's net worth, prospective earning power and
        dividend-paying capacity, the goodwill of the Company's business, the
        issuer's industry position and its management, that Company's economic
        outlook, the values of securities of issuers whose stock is publicly
        traded and which are engaged in similar businesses, the effect of
        transfer restrictions to which such Common Shares may be subject under
        law and under the applicable terms of any contract governing such stock,
        the absence of a public market for such Common Shares and such other
        matters as the Board or its appraiser or appraisers deem pertinent. The
        determination by the Board or its appraiser or appraisers of the Fair
        Market Value shall, if not unreasonable, be conclusive and binding
        notwithstanding the possibility that other persons might make a
        different, and also reasonable, determination. If the Fair Market Value
        to be used was thus fixed



                                       4
<PAGE>   5



        more than sixteen months prior to the day as of which Fair Market Value
        is being determined, it shall in any event be no less than the book
        value of the Common Shares being valued at the end of the most recent
        period for which financial statements of the issuer are available; or

                      (ii) If the Common Shares are publicly traded on the
        business day immediately preceding the Determination Date, then Fair
        Market Value shall equal the closing price per Common Share or unit of
        such other security on the business day immediately preceding the
        Determination Date, as reported in The Wall Street Journal, Western
        Edition (or, if such day is not a trading day in the principal
        securities market or markets for such Common Shares, on the nearest
        preceding trading day), as reported with respect to the market (or the
        composite of markets, if more than one) in which shares of such Common
        Shares are then traded, or, if no such closing prices are reported, on
        the basis of the mean between the high bid and low asked prices that day
        on the principal market or quotation system on which Common Shares are
        then quoted, or, if not so quoted, as furnished by a professional
        securities dealer making a market in the Common Shares selected by the
        Board or the Committee.

SECTION 6.  DURATION OF PLAN

               Options shall not be granted under this Plan after March 17,
2009. Although Common Shares may be issued on or after March 17, 2009 pursuant
to Options granted prior to such date, no Common Shares shall be issued under
this Plan after March 16, 2019.

SECTION 7.  ADMINISTRATION OF PLAN

               (a) This Plan shall be administered by a committee (the
"Committee") of the Board of Directors of the Company (the "Board") consisting
of two or more directors, each of whom is a "non-employee director" (as such
term is defined in Rule 16b-3 promulgated under the Exchange Act, as such Rule
may be amended from time to time); provided, however, that in the event the
Committee is not comprised of two or more "non-employee directors," then (i) the
Committee shall only be authorized and empowered to recommend to the Board all
things necessary or desirable in connection with the administration of this
Plan, including, without limitation, the things listed in Section 7, (ii) all
recommendations of the Committee relating to this Plan shall be subject to final
approval by the Board and (iii) all references herein to the Committee shall be
deemed to refer to the Board; provided further, that unless otherwise determined
by the Board, with respect to any Award that is intended to qualify as
Performance-Based Compensation, the Plan shall be administered by a committee
consisting of two or more directors, each of whom is an "outside director" (as
such term is defined under Section 162(m) of the Code).

               (b) Subject to the provisions of this Plan, the Committee shall
be authorized and empowered to do all things necessary or desirable in
connection with the administration of this Plan, including, without limitation,
the following:




                                       5
<PAGE>   6

                      (i) adopt, amend and rescind rules and regulations
        relating to this Plan;

                      (ii) determine which persons are Employees and to which of
        such Employees, if any, Awards shall be granted hereunder;

                      (iii) grant Awards to Employees and Nonemployee Directors
        (provided that Nonemployee Directors shall not be eligible to be
        considered for the grant of Incentive Stock Options) and determine the
        terms and conditions thereof, including (A) the number of Common Shares
        issuable pursuant thereto and (B) the exercise price for any Awards;

                      (iv) determine whether, and the extent to which,
        adjustments are required pursuant to Section 8 hereof; and

                      (v) interpret and construe this Plan and the terms and
        conditions of all Awards granted hereunder.

SECTION 8.  ADJUSTMENTS

               If the outstanding securities of the class then subject to this
Plan are increased, decreased or exchanged for or converted into cash, property
or a different number or kind of securities, or if cash, property or securities
are distributed in respect of such outstanding securities, in either case as a
result of a reorganization, merger, consolidation, recapitalization,
restructuring, reclassification, dividend (other than a regular, quarterly cash
dividend) or other distribution, stock split, reverse stock split or the like,
or if substantially all of the property and assets of the Company are sold,
then, unless the terms of such transaction shall provide otherwise, the
Committee may make appropriate and proportionate adjustments in (a) the number
and type of shares or other securities or cash or other property that may be
acquired pursuant to Incentive Stock Options and other Awards theretofore
granted under this Plan, (b) the maximum number and type of shares or other
securities that may be issued pursuant to Incentive Stock Options and other
Awards thereafter granted under this Plan, and (c) the maximum number of Common
Shares for which options may be granted during any one calendar year; provided,
however, that no adjustment shall be made under this Section 8 to the number of
Common Shares that may be acquired pursuant to outstanding Incentive Stock
Options or the maximum number of Common Shares with respect to which Incentive
Stock Options may be granted under this Plan to the extent such adjustment would
result in such options being treated as other than Incentive Stock Options;
provided further that no such adjustment shall be made to the extent the
Committee determines that such adjustment would result in the disallowance of a
federal income tax deduction for compensation attributable to Options hereunder
by causing such compensation to be other than Performance-Based Compensation.

<PAGE>   7


SECTION 9.  AMENDMENT AND TERMINATION OF PLAN

               The Board may amend or terminate this Plan at any time and in any
manner; provided, however, that no such amendment or termination shall deprive
the recipient of any Award theretofore granted under this Plan, without the
consent of such recipient, of any of his or her rights thereunder or with
respect thereto; provided, further, that the Board shall not, without the
approval of the shareholders of the Company, amend the Plan in any manner that
requires such shareholder approval pursuant to the Code or any applicable
securities laws.

SECTION 10.  EFFECTIVE DATE OF PLAN

               The Stock Incentive Plan shall be effective as of March 18,
1999, the date upon which it was approved by the Board; provided, however, that
no Awards may be granted nor may Common Shares be issued under this Stock
Incentive Plan until it has been approved, directly or indirectly, by the
affirmative votes of the holders of a majority of the securities of the Company
present, or represented, and entitled to vote at a meeting duly held in
accordance with the laws of the State of Delaware.

SECTION 11.  COMPLIANCE WITH OTHER LAWS AND REGULATIONS

        This Plan, the grant and exercise of Awards thereunder, and the
obligation of the Company to sell and deliver Common Shares under such Awards,
shall be subject to all applicable federal and state laws, rules and regulations
and to such approvals by any governmental or regulatory agency as may be
required. The Company shall not be required to issue or deliver any certificates
for shares of Common Stock prior to the completion of any registration or
qualification of such shares under any federal or state law or issuance of any
ruling or regulation of any government body which the Company shall, in its sole
discretion, determine to be necessary or advisable.

SECTION 12.  NO RIGHT TO COMPANY EMPLOYMENT

        Nothing in this Plan or as a result of any Award granted pursuant to
this Plan shall confer on any individual any right to continue in the employ of
the Company or any of its subsidiaries or affiliates or interfere in any way
with the right of the Company (or its subsidiaries or affiliates, as applicable)
to terminate an individual's employment at any time, with or without cause. The
agreement evidencing an Award may contain such provisions as the Committee may
approve with respect to the effect of approved leaves of absence.

SECTION 13.  LIABILITY OF COMPANY

        The Company and any affiliate which is in existence or hereafter comes
into existence shall not be liable to an Employee, Nonemployee Director or other
persons as to:

regulatory body having jurisdiction the authority deemed by the Company's
counsel to be necessary to the lawful issuance and sale of any Shares hereunder;
and

<PAGE>   8


               (b) Tax Consequences. Any tax consequence expected, but not
realized, by any Employee or Nonemployee Director or other person due to the
issuance, exercise, settlement, cancellation or other transaction involving any
Award granted hereunder.

        be the rate 5.000% above the Treasury Rate in effect as of the close of
        business on the Thursday of the week preceding disbursement of the
        Advance; provided, however, that such interest rate shall be rounded to
        the nearest 0.05%.

        PAYMENTS: Borrower shall pay principal of and interest on each Advance
        on the fifth day of each month in equal successive monthly installments

        96 months, as agreed by Borrower and Bank at the time of such Advance,
        depending on the type of equipment financed and the interest rate
        applicable at the time of such Advance. If the Advance occurs on or
        before the eighteenth day of a month, the first payment due date shall
        be the 5th day of the next month; if the Advance occurs after the
        eighteenth day of a month, the first payment due date shall be the 5th
        day of the second month following the Advance. All unpaid principal and

        prepayment fee equal to (i) 5% of the amount prepaid if the remaining
        term is five or more years, (ii) 4% of the amount prepaid if the
        remaining term is four to five years, (iii) 3% of the amount prepaid if
        the remaining term is three to four years, (iv) 2% of the amount prepaid
        if the remaining term is two to three years, and (v) 1% of the amount
        prepaid if the remaining term is one to two years. All prepayments of

        of each month in equal successive monthly installments sufficient to

        the interest rate applicable at the time of such Advance. In addition,
        Borrower shall pay all accrued unpaid interest on each payment date. If
        the Advance occurs on or before the eighteenth day of a month, the first
        payment due date shall be the 5th day of the next month; if the Advance

     or not this was or should have been known to Borrower. Borrower releases
     and waives any future claims against Bank for damages, indemnity or
     contribution in connection with Hazardous Substances. The provisions of
     this section of the Disclosure, including the obligation to indemnify, will
     survive the repayment of the Credit and the termination or expiration of

     rights, offers to purchase the Collateral or any similar matters whether or
     not Bank has any knowledge of them.

     Bank will have no duty to take any steps necessary to preserve the rights
     of Grantor against prior parties, or to initiate any action to protect
     against the possibility of a decline in the market value of the Collateral.

<PAGE>   15
     Bank will not be obligated to take any action with respect to the 
     Collateral requested by Grantor unless the request is made in writing and

     unreasonably jeopardize the value of the Collateral. Bank may at any time 
     deliver the Collateral, or any part of it, to any Grantor, and the receipt 
     thereof by any Grantor will be a complete and full acquittance for the 
     Collateral delivered. Bank will then have no further liability or 
     responsibility for the Collateral delivered.

     whether or not the deposits have matured and notwithstanding the fact that 
     such liquidation may give rise to penalties for early withdrawal of funds; 
     (e) liquidate the Collateral and apply all Proceeds toward repayment of 
     the credit obligation in such order of application as Bank may from time 
     to time elect or, at Bank's sole option, place any Proceeds in the cash 
     collateral account; (f) without notice to Grantor, enter on to Grantor's 
     premises and care for and harvest any or Grantor's Collateral that is 
     growing crops, with all expenses of care and harvesting to be paid by 
     Grantor; and (g) exercise all rights of a secured party under the 
     Commercial Code and other applicable law.

     To the extent allowable by the law, it is agreed that public or private 
     sales (for cash or on credit, to a wholesaler, retailer, investor, or user 
     of collateral of the types subject to the Agreement) or public auction are 
     all commercially reasonable.

2.7  DISPOSITION OF COLLATERAL
- -------------------------------------------------------------------------------

     Any proceeds of any disposition of any of the Collateral may be applied by 
     Bank to the payment of expenses incurred by Bank in connection with the 
     disposition, including reasonable attorney's fees; the balance of such 
     proceeds may be applied by Bank toward the payment of the Credit and in 
     such order of application as Bank may from time to time elect. Any money 
     received by Bank in respect of the Collateral will, for all purposes, be 
     deemed Collateral and may, at Bank's option, be retained in a non-interest 
     bearing cash collateral account. While Borrower is not in default, Bank 
     will -- except to the amount of contingent liabilities secured -- either 
     release or apply to any debt secured by the Agreement, at Bank's option, 
     all security in the form of cash or irrevocable bank credit. Any sums 
     withheld to secure contingent liabilities may be deposited at Bank's 
     option in a non-interest bearing account over which Grantor will have no 
     control.

2.8  TRANSFER OF COLLATERAL
- -------------------------------------------------------------------------------

     Upon the transfer of all or any part of the Credit, Bank may transfer all 
     or any part of the Collateral and will have no liability and 
     responsibility with respect to the Collateral so transferred. The 
     transferee will be vested with all the rights of Bank under the Agreement 
     with respect to the Collateral; but with respect to any part of the 
     Collateral not transferred. Bank shall retain all rights, powers, 
     privileges and remedies granted under this Agreement.

2.9  ARBITRATION
- -------------------------------------------------------------------------------

     Bank, Grantor, and any other party to this Agreement agree to be bound by 
     the terms and provisions of Arbitration Program set forth in Appendix B of 
     this Disclosure, by which Disputes shall be resolved by binding 
     arbitration upon the request of any party.

2.10 MISCELLANEOUS
- -------------------------------------------------------------------------------

     The obligations of Grantor are joint and several. Grantor hereby waives 
     any right to require Bank to make any presentment or demand, or give any 
     notice of nonpayment or nonperformance, protest, notice of protest, notice 
     of dishonor, notice of intention to accelerate or notice of acceleration 
     hereunder, to direct the application of payments or security for credit 
     obligation(s) of Borrower under the Agreement, or indebtedness owed to 
     customers of Borrower, and to require proceedings against others or to 
     require exhaustion of security.

     Grantor consents to extensions, forbearances, or alterations of the terms 
     of the Credit, the release or substitution of Collateral, and the release 
     of Guarantors.


                                       7
<PAGE>   16

     Until the Credit is paid in full, Grantor will have no right of 
     subrogation or contribution, and Grantor hereby waives any benefit of or 
     any right to participate in any Collateral or other security whatsoever 
     now or hereafter held by Bank.

     In addition, Bank, Grantor, and any other party to this Agreement agree to 
     be bound by the miscellaneous provisions set forth in Appendix A of this 
     Disclosure.

2.11 ADDITIONAL TERMS FOR SPECIFIC TYPES OF COLLATERAL
- -------------------------------------------------------------------------------

     The following additional terms and conditions apply only to specific types 
     of Collateral and are in addition to -- and not a substitute for -- those 
     listed in the other sections of this Disclosure.

  INVENTORY

     RESPONSIBILITIES OF GRANTOR:

     Grantor agrees: (a) not to remove inventory from Grantor's premises 
     without the prior written consent of Bank and upon such terms and 
     conditions as Bank may require -- except sales to buyers in the ordinary 
     course of business and inventory that consists of mobile goods as defined 
     in the Uniform Commercial Code, in which case, Grantor agrees not to 
     remove or permit the removal of the inventory from its current location as 
     shown in the Confirmation Letter for a period in excess of thirty (30) 
     calendar days; and (b) to furnish reports to Bank of all acquisitions, 
     returns, sales, and other dispositions of the inventory in such form and 
     detail and at such times as Bank may require.

     REMEDIES:

     With respect to any sale by Bank of any inventory subject to the 
     Agreement, Grantor expressly grants to Bank the right to sell the 
     inventory using any or all of Grantor's trade names, trade name rights, 
     and/or proprietary labels or marks.

  SECURITIES

     RESPONSIBILITIES OF GRANTOR:

     Grantor agrees: (a) to vote the securities and to give consents, waivers,
     and ratifications with respect to them -- provided that no vote will be
     cast or consent, waiver or ratification given or action taken that would
     impair Bank's interests in the Collateral; (b) if requested by Bank, to
     receive and use reasonable diligence to collect securities, rights to
     payment, and proceeds, in trust and as the property of Bank, and
     immediately endorse (if appropriate) and deliver them to Bank daily in the
     exact form in which they are received together with a collection report in
     a form satisfactory to Bank; and (c) in the event Bank elects to receive
     payments of securities, rights to payment, or proceeds, to pay all expenses
     incurred by Bank in receiving and processing them, including expenses of
     accounting, correspondence, collection efforts, reporting to account or
     contract debtors, filing, recording, record keeping, and incidental related
     expenses.

     REMEDIES:

     If an event of default has occurred and is continuing, Bank will be under 
     no obligation to delay a sale of any portion of the securities for the 
     period of time necessary to permit the issuer of the securities to 
     register them for public sale under any applicable state or federal law -- 
     even if the issuer would agree to do so. Any or all Collateral consisting 
     of securities may be registered, without notice, in the name of Bank or 
     its nominee, and thereafter Bank or its nominee may exercise, without 
     notice: (a) all voting and corporate rights at any meeting of the 
     shareholders of the securities issuer; and (b) any and all rights of 
     conversion, exchange, or subscription, or any other rights, privileges or 
     options pertaining to any Collateral, as if it were the absolute owner of 
     the securities. The foregoing shall include, without limitation, the right 
     of Bank or its nominee to exchange, at its discretion, any and all 
     Collateral upon the merger, consolidation, reorganization, 
     recapitalization or other readjustment of the issuer thereof, or upon the 
     exercise by the issuer thereof or Bank of any right, privilege or option 
     pertaining to any shares of the Collateral, and in connection therewith, 
     the right to deposit and deliver any and all of the Collateral with any 
     committee, depository, transfer agent, registrar or other designated 
     agency upon such terms and conditions as Bank may determine.

     All of these rights, privileges, and options may be exercised without 
     liability, except to account for property actually received by Bank. Bank 
     will have no duty to exercise any of the foregoing -- or any other rights, 
     privileges, or options -- and will not be responsible for any failure to 
     do so or delay in so doing.

- --------------------------------------------------------------------------------
SECTION 3                           GUARANTY
- --------------------------------------------------------------------------------

By signing the Confirmation Letter, Guarantor agrees, unless otherwise 
disclosed to and acknowledged by Bank in writing, that the following is true
now, and at the time of each advance will be true:

3.1  CONTINUING GUARANTY
- --------------------------------------------------------------------------------
     For valuable consideration, Guarantor absolutely and unconditionally 
     guarantees and promises to pay to Bank or its order, the indebtedness of 
     Borrower to Bank on the terms and conditions set forth in the Agreement. 
     IF MORE THAN ONE GUARANTOR EXECUTES THE AGREEMENT, THE LIABILITY OF EACH 
     AND EVERY GUARANTOR (COLLECTIVELY REFERRED TO HEREIN AS "GUARANTOR") SHALL 
     BE JOINT AND SEVERAL. The maximum liability of each Guarantor under this 
     Agreement shall not exceed the sum of the principal amount set forth in 
     the Confirmation Letter for such Guarantor, plus all interest thereon, 
     plus all of Bank's costs, expenses, and attorney's fees incurred in 
     connection with or relating to the collection of the Indebtedness, the 
     collection and sale of any collateral for the Indebtedness or this 
     Agreement, and the enforcement of this Agreement.

     The above limitation on liability is not a restriction on the amount of 
     the Indebtedness of Borrower to Bank either in the aggregate or at any one 
     time. If Bank presently holds one or more guaranties, or hereafter 
     receives additional guaranties from Guarantor, the rights of Bank under 
     all guaranties shall be cumulative. This Guaranty shall not (unless 
     specifically provided below to the contrary) affect or invalidate any such 
     other guaranties. Guarantor's liability under this Guaranty shall be open 
     and continuous for so long as this Guaranty remains in force. Guarantor 
     intends to guaranty at all times the performance and prompt payment when 
     due, whether at maturity or earlier by reason of acceleration or 
     otherwise, of all Indebtedness within the limits (if any) of the Guaranty 
     set forth in this Agreement. Accordingly, no payments made upon the 
     Indebtedness will discharge or diminish the continuing liability of 
     Guarantor in connection with any remaining portions of the Indebtedness or 
     any of the Indebtedness which subsequently arises or is thereafter 
     incurred or contracted. Any married person who signs this Guaranty as the 
     Guarantor hereby expressly agrees that recourse may be had against both 
     his or her separate property and community property.

3.2  DURATION OF GUARANTY
- --------------------------------------------------------------------------------
     This Guaranty will take effect when received by Bank without the necessity 
     of any acceptance by Bank, or any notice to Guarantor or to Borrower, and 
     will continue in full force until all Indebtedness incurred or contracted 
     before receipt by Bank or any notice of revocation shall have been fully 
     and finally paid and satisfied, and all other obligations of Guarantor 
     under this Guaranty shall have been performed in full.

     If Guarantor elects to revoke this Guaranty, Guarantor may only do so in 
     writing. Guarantor's written notice of revocation must be mailed to Bank, 
     by certified mail, at the address of Bank listed on the Confirmation 
     Letter or such other place as Bank may designate in writing. Written 
     revocation of this Guaranty will apply only to advances or new 
     Indebtedness created after actual receipt by Bank of Guarantor's written 
     revocation. For this purpose and without limitation, the term "new 
     Indebtedness" does not include Indebtedness which at the time of notice of 
     revocation is contingent, unliquidated, undetermined or not due and which 
     later becomes absolute, liquidated, determined or due. This Guaranty will 
     continue to bind Guarantor for all Indebtedness incurred by Borrower or 
     committed by Bank prior to receipt of Guarantor's written notice of 
     revocation, including any extensions, renewals, substitutions or 
     modifications of such Indebtedness.

     This Guaranty shall bind the estate of Guarantor as to Indebtedness 
     created both before and after the death or incapacity of Guarantor, 
     regardless of Bank's actual notice of Guarantor's death. Subject to the 
     foregoing, Guarantor's executor or administrator or other legal 
     representative may terminate this Guaranty in the same manner in which 
     Guarantor might have terminated it and with the same effect. Release of 
     any other Guarantor or termination of any other Guaranty of the 
     Indebtedness shall not affect the liability of Guarantor under this 
     Guaranty. A revocation received by Bank from any one or more Guarantor's 
     shall not affect the liability of any remaining Guarantor(s) under 
     this Guaranty.



                                       9
<PAGE>   18
     it is anticipated that fluctuations may occur in the aggregate amount of
     Indebtedness covered by this Guaranty and it is specifically acknowledged
     and agreed by Guarantor that reductions in the amount of Indebtedness even
     to zero dollars ($0.00), prior to written revocation in this Guaranty by
     Guarantor shall not constitute a termination of this Guaranty.

3.3  GUARANTOR'S AUTHORIZATION TO BANK

     Guarantor authorizes Bank, either before or after any revocation hereof, 
     without notice or demand and without lessening Guarantor's liability under 
     this Guaranty, from time to time: (a) prior to revocation as set forth 
     above to make one or more additional secured or unsecured loans to 
     Borrower, to lease property to Borrower, or otherwise to extend additional 
     credit to Borrower; (b) to alter, compromise, renew, extend, accelerate or 
     otherwise change the time for payment or other terms of the Indebtedness 
     or any part of the Indebtedness including increases and decreases of the 
     rate of interest on the Indebtedness; extensions may be repeated and may 
     be for longer than the original loan term; (c) to take and hold security 
     for the payment of this Guaranty or the Indebtedness, and exchange, 
     enforce, waive, subordinate, fail or decide not to perfect, and release any
     such security, with or without the substitution of new Collateral; (d) to 
     release, substitute, agree not to sue, settle or deal with any one or more 
     of Borrower's sureties, endorsers or other Guarantors on any terms or in 
     any manner Bank may choose; (e) to determine how, when and what 
     application of payments and credits shall be made on the Indebtedness;
     (f) to apply such security and direct the order or manner of sale thereof,
     including without limitation, any nonjudicial sale permitted by the terms
     of any security agreement or deed of trust, as Bank in its discretion may
     determine; and (g) to assign or transfer this Guaranty in whole or in part.

3.4  GUARANTOR'S REPRESENTATIONS AND WARRANTIES

     Guarantor represents and warrants to Bank that: (a) no representations or
     agreements of any kind have been made to Guarantor as to the credit
     worthiness of Borrower which would limit or qualify in any way the terms of
     this Guaranty; (b) upon Bank's request Guarantor will provide to Bank
     financial and credit information in form acceptable to Bank, and all such
     financial information which currently has been, and all future financial
     information which will be provided to Bank is and will be true and correct
     in all material respects and fairly present the financial condition of
     Guarantor as of the dates the financial information is provided; (c) no
     material adverse change has occurred in Guarantor's financial condition
     since the date of the most recent financial statements provided to Bank and
     no event has occurred which may materially adversely affect Guarantor's
     financial condition, and Guarantor agrees to the extent possible to not do
     or allow anything in the future which would adversely affect the
     Guarantor's financial condition; and (d) Guarantor has established adequate
     means of obtaining from Borrower on a continuing basis information
     regarding Borrower's financial condition and will keep adequately informed
     from such means of any facts, events or circumstances which might in any
     way affect Guarantor's risks under this Guaranty. Bank shall have no
     obligation to disclose to Guarantor any information or documents acquired
     by Bank in the course of its relationship with Borrower.

3.5  GUARANTOR'S WAIVERS

     Except as prohibited by applicable law, Guarantor waives any right to 
     require Bank to: (a) make any presentmemt, protest, demand or notice of 
     any kind, including notice of change of any terms of repayment of the 
     Indebtedness, default by Borrower or any other guarantor or surety, any 
     action or nonaction taken by Borrower, Bank or any other guarantor or 
     surety of Borrower, or the creation of new or additional Indebtedness;
     (b) proceed against any Collateral or any person, including Borrower,
     before proceeding against Guarantor; (c) apply any payments or proceeds
     received against the Indebtedness in any order; (d) give notice of the
     terms, time and place of any sale of the Collateral pursuant to the Uniform
     Commercial Code or any other law governing such sale; (e) disclose any
     information about the Indebtedness, Borrower, the Collateral, or any other
     guarantor or surety, or about any action or nonaction of Bank; or
     (f) pursue any remedy or course of action in Bank's power whatsoever.

     Guarantor also waives any and all rights or defenses arising by reason of: 
     (a) any disability or other defense of Borrower, any other guarantor or 
     surety or any other person; (b) the cessation from any cause whatsoever, 
     other than payment in full, of the Indebtedness; (c) the application of 
     proceeds of the Indebtedness by Borrower for purposes other than the 
     purposes understood and intended by Guarantor and Bank; (d) any act of 

     

                                       10
<PAGE>   19
     omission or commission by Bank which directly or indirectly results in or
     contributes to the discharge of Borrower or any other guarantor or surety,
     or the Indebtedness, or the loss or release of any Collateral by operation
     of law or otherwise: (e) any statutes of limitations in any action under
     this Guaranty or on the Indebtedness; or (f) any modification or change in
     terms of the Indebtedness whatsoever, including without limitation, the
     renewal, extension, acceleration or other change in the time payment of the
     Indebtedness is due and any change in the interest rate, and including any
     such modification or change in terms after revocation of this Guaranty on
     Indebtedness incurred prior to such revocation.

     Until all Indebtedness is paid in full, Guarantor waives all rights and any
     defenses Guarantor may have arising out of an election of remedies by Bank
     even though that election of remedies, such as a nonjudicial foreclosure
     with respect to security for a guarantied obligation, has destroyed
     Guarantor's rights of subrogation and reimbursement against Borrower or any
     other guarantor or surety by operation of Section 580a, 580b, 580d and 726
     of the California Code of Civil Procedure or otherwise. This waiver
     includes, without limitation, any loss of rights Guarantor may suffer by
     reason of any rights or protections of Borrower in connection with any
     anti-deficiency laws or other laws limiting or discharging the Indebtedness
     or Borrower's obligations (including, without limitation, Sections 726,
     580a, 580b, and 580d of the California Code of Civil Procedure). Guarantor
     waives all rights and protections of any kind which Guarantor may have for
     any reason, which would affect or limit the amount of any recovery by Bank
     from Guarantor following a nonjudicial sale or judicial foreclosure of any
     real or personal property security for the Indebtedness including, but not
     limited to, the right to any fair market value hearing pursuant to
     California Code of Civil Procedure Section 580a.

     Guarantor understands and agrees that the foregoing waivers are waivers of
     substantive rights and defenses to which Guarantor might otherwise be
     entitled under state and federal law. The rights and defenses waived
     include, without limitation, those provided by California laws of
     suretyship and guaranty, anti-deficiency laws, and the Uniform Commercial
     Code. Guarantor acknowledges that Guarantor has provided these waivers of
     rights and defenses with the intention that they be fully relied upon by
     Bank. Until all Indebtedness is paid in full, Guarantor waives any right to
     enforce any remedy Bank may have against Borrower or any other guarantor,
     surety, or other person, and further, Guarantor waives any right to
     participate in any Collateral for the Indebtedness now or hereafter held by
     Bank.

     Guarantor warrants and agrees that each of the waivers set forth above is
     made with Guarantor's full knowledge of its significance and consequences
     and that under the circumstances, the waivers are reasonable and not
     contrary to public policy or law. If any such waiver is determined to be
     contrary to any applicable law or public policy, such waiver shall be
     effective only to the extent permitted by law or public policy.

3.6  BANK'S RIGHT OF SETOFF
- -------------------------------------------------------------------------------

     In addition to all liens upon and rights of setoff against the moneys,
     securities or other property of Guarantor given to Bank by law, Bank shall
     have, with respect to Guarantor's obligations to Bank under this Guaranty
     and to the extent permitted by law, a contractual possessory security
     interest in and a right of setoff against, and Guarantor hereby assigns,
     conveys, delivers, pledges and transfers to Bank all of Guarantor's right,
     title and interest in and to, all deposits, moneys, securities and other
     property of Guarantor now or hereafter in the possession or on deposit
     with Bank, whether held in a general or special account or deposit, whether
     held jointly with someone else, or whether held for safekeeping or
     otherwise, excluding however all IRA and Keogh accounts. Every such
     security interest and right of setoff may be exercised without demand upon
     or notice to Guarantor.

3.7  SUBORDINATION OF BORROWER'S DEBTS TO GUARANTOR
- -------------------------------------------------------------------------------

     Guarantor agrees that the Indebtedness of Borrower to Bank, whether now
     existing or hereafter created, shall be prior to any claim that Guarantor
     may now have or hereafter acquire against Borrower, whether or not Borrower
     becomes insolvent. Guarantor hereby expressly subordinates any claim
     Guarantor may have against Borrower, upon any account whatsoever, to any
     claim that Bank may now or hereafter have against Borrower. In the event of
     insolvency and consequent liquidation of the assets of Borrower, through
     bankruptcy, by an assignment for the benefit of creditors, by voluntary
     liquidation, or otherwise, the assets of Borrower applicable to the payment
     of the claims of both Bank and Guarantor shall be paid to Bank and shall



                                       11
<PAGE>   20
     be first applied by Bank to the indebtedness of Borrower to Bank. 
     Guarantor does hereby assign to Bank all claims which it may have or 
     acquire against Borrower or against any assignee or trustee in bankruptcy 
     of Borrower; provided however, that such assignment shall be effective 
     only for the purpose of assuring to Bank full payment in legal tender of 
     the Indebtedness. If Bank so requests, any notes or credit agreements now 
     or hereafter evidencing any debts or obligations of Borrower to Guarantor 
     shall be marked with a legend that the same are subject to this Guaranty 
     and shall be delivered to Bank. Guarantor agrees, and Bank hereby is 
     authorized, in the name of Guarantor, from time to time to execute and 
     file financing statements and continuation statements and to execute such 
     other documents and to take such other actions as Bank deems necessary or 
     appropriate to perfect, preserve and enforce its rights under this 
     Guaranty.

3.8 ARBITRATION
- --------------------------------------------------------------------------------

     Bank, Guarantor, and any other party to this Agreement agree to be bound 
     by the terms and provisions of Arbitration Program set forth in Appendix B 
     of this Disclosure, by which Disputes shall be resolved by binding 
     arbitration upon the request of any party.

3.9 MISCELLANEOUS
- --------------------------------------------------------------------------------
     The following miscellaneous provisions are a part of this Guaranty:

     The obligations of Guarantor are joint and several. Guarantor hereby 
     waives any right to require Bank to make any presentment or demand, or 
     give any notice of nonpayment or nonperformance, protest, notice of 
     protest, notice of dishonor, notice of intention to accelerate or notice 
     of acceleration hereunder, to direct the application of payments or 
     security for credit obligation(s) of Borrower under the Agreement, or 
     indebtedness owed to customers of Borrower, and to require proceedings 
     against others or to require exhaustion of security.

     Guarantor consents to extensions, forbearances, or alterations of the 
     terms of the Credit, the release or substitution of Collateral, and the 
     release of Borrower, Grantor, and any Guarantors.

     Until the Credit is paid in full, Guarantor will have no right of 
     subrogation or contribution, and Guarantor hereby waives any benefit of or 
     any right to participate in any Collateral or other security whatsoever 
     now or hereafter held by Bank.

     In addition, Bank, Guarantor, and any other party to this Agreement agree 
     to be bound by the miscellaneous provisions set forth in Appendix A of 
     this Disclosure.



                                       12

- --------------------------------------------------------------------------------
APPENDIX A                 MISCELLANEOUS PROVISIONS
- --------------------------------------------------------------------------------



In addition to the general terms and conditions set forth above, the following
additional provisions are included as a part of Sections 1, 2, and 3 of this
Business Lending Disclosure, wherein the term "you" means and refers to

and correspondence concerning these matters. The terms of this Agreement may be

party or parties to be bound by the change. This Agreement will be binding on 
and may be enforced by the respective successors, assigns, administrators, 
executors and heirs of you and Bank; however, you may not assign or transfer 
any interest or rights without the prior written consent of Bank.

APPLICABLE LAW

applicable federal law. If the Confirmation Letter identifies Bank as Wells 
Fargo Bank (Texas), N.A., this Agreement will be governed by the laws of the 
State of Texas and applicable federal law, with respect to lines of credit, the 
parties agree that Chapter 15 of the Texas Credit Code shall not apply. To the 
extent that Bank has greater rights or remedies under federal law, the choice 
of state law will not be deemed to deprive Bank of the rights and remedies 
available under federal law. If the Bank enforces its rights and/or initiates 
collection of any amounts that become due to Bank under the Agreement, to the 
extent that Bank has greater rights or remedies under the law of the forum 
state, the choice of state law will not be deemed to deprive Bank of the rights 
and remedies available under the law of the forum state.

connection with the enforcement of the Bank's rights regarding your obligations

other costs and expenses of such enforcement efforts. Costs and expenses

well as allocated costs of Bank's in-house counsel), and legal expenses whether 
or not there is a lawsuit, including attorney's fees and legal expenses for 
bankruptcy proceedings (and including efforts to modify or vacate any automatic 
stay or injunction), appeals, and any anticipated post-judgment collection

    otherwise to demand strict compliance with that provision or any other
    provision of this Agreement. No prior waiver by Bank, nor any course of
    dealing between you and Bank, shall constitute a waiver of any of Bank's
    rights or of any of your obligations as to any future transactions. Whenever

    consent by Bank in any instance shall not constitute continuing consent to
    subsequent instances where such consent is required and in all cases such
    consent may be granted or withheld in the sole discretion of Bank.

APPENDIX B                     ARBITRATION PROGRAM
- --------------------------------------------------------------------------------

In addition to the General Terms and Conditions set forth above, the following
terms and conditions also apply to the Disclosure, Confirmation Letter, and
other Related Documents.

    BINDING ARBITRATION

    Any of the Bank, Borrower, Guarantor, Grantor, or any other party to the
    Disclosure, the Confirmation Letter, or any other Related Document may
    require that any Dispute be resolved by binding arbitration in accordance
    with the terms of this Arbitration Program, administered by the American
    Arbitration Association (the "AAA") pursuant to its Commercial Arbitration
    Rules and the Federal Arbitration Act (Title 9 of the United States Code).
    DISPUTES SUBMITTED TO ARBITRATION ARE NOT RESOLVED IN COURT BY A JUDGE OR
    JURY. Any party who fails to submit to binding arbitration following a
    lawful demand by the opposing party shall bear all costs and expenses
    incurred by the opposing party in compelling arbitration of a Dispute.
    Arbitration may be demanded at any time, and may be compelled by summary
    proceedings in Court.

      ARBITRATORS; PRESERVATION OF REMEDIES

      A Dispute involving claims or amounts in controversy of $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), and
      each party expressly waives any right or claim to recover more than
      $5,000,000 in such cases. A Dispute involving greater amounts shall be
      heard by and decided by a majority vote of a panel of three (3)
      arbitrators. Every arbitrator must be a retired member of the state or
      federal judiciary or a practicing attorney experienced and knowledgeable
      in the substantive laws applicable to the subject matter of the Dispute.
      Arbitrator(s) (i) may grant any remedy or relief within the scope hereof
      that a court of competent jurisdiction could, including ancillary relief
      as is necessary to make effective any award, (ii) shall have the power to
      award recovery of all costs and fees, and (iii) may impose sanctions and
      take other actions as they deem necessary to the same extent a judge
      could. The determination of the arbitrator(s) shall be binding on all
      parties and shall not be subject to further review or appeal except as
      otherwise allowed by applicable law. Judgment upon an award made hereunder
      may be entered in any court having jurisdiction. Any claim or dispute
      related to the exercise of any self-help, auxiliary or other rights under
      this paragraph shall be a Dispute hereunder. However, no provision of, nor
      the exercise of any rights under, this Arbitration Program shall limit the
      right of any party to seek, use, and employ ancillary or preliminary
      remedies, judicial or otherwise, for the purposes of (i) preserving,
      foreclosing, or obtaining possession of real or personal property, (ii)
      exercising self-help remedies including setoff and repossession rights, or
      (iii) obtaining provisional or ancillary remedies such as injunctive
      relief, sequestration, attachment, garnishment, or the appointment of a
      receiver from a court having jurisdiction. Such rights can be exercised at
      any time, unless contrary to a final award or decision in an arbitration
      proceeding, and shall not constitute a waiver of the arbitration rights of
      any party. The involvement of any party in judicial or other proceedings
      as plaintiff or in any other capacity shall not impair such party's rights
      to demand arbitration of the Dispute at any reasonable time. Any party may
      proceed against all liable persons, or against any one or more of them,
      and may release or settle with any of them, without impairing rights
      against other liable persons.

      JUDICIAL REVIEW; REAL PROPERTY COLLATERAL; JUDICIAL REFERENCE

      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 applicable substantive law, 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 whether the findings of fact
      rendered by the arbitrators are supported by substantial evidence, and
      whether the conclusions of law are erroneous under applicable substantive
      law. 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 applicable substantive law. Notwithstanding
      contrary provisions herein, no Dispute shall be submitted to arbitration
      if the Dispute concerns indebtedness secured by real property and if
      arbitration of the Dispute would preclude enforcement of a mortgage, lien
      or security interest securing such indebtedness, unless the holder of such
      mortgage, lien or security interest specifically elects in writing to
      proceed with the arbitration. If such a Dispute is not submitted to
      arbitration under such circumstances, the Dispute shall be determined by
      Judicial Reference at the election of any Party. If such an election is
      made, the Dispute shall be determined by a reference in accordance with
      California Code of Civil Procedure Section 638, et seq., or the judicial
      reference procedures of some other state if such state in which the real
      property is located offers a comparable judicial reference procedure. A
      referee shall be selected pursuant to AAA procedures and must meet the
      selection criteria set forth herein for an arbitrator.

      MISCELLANEOUS

      To the maximum extent practicable, the AAA, the arbitrator and the parties
      shall act to assure that any arbitration proceeding shall be concluded
      within 180 days of the filing of the Dispute with the AAA. Arbitration
      proceedings hereunder shall be conducted at a location mutually agreeable
      to the parties, or if they cannot agree, then in the state of the
      applicable substantive law designated in the Documents relating to the
      Dispute at a location selected by the AAA. All discovery activities shall
      be expressly limited to matters directly relevant


                                       15
<PAGE>   24

      to the Dispute. No party or arbitrator may disclose the existence, 
      content or results of any arbitration hereunder, except for disclosures 
      of information required in the ordinary course of a party's business or 
      by applicable law or regulation. The parties agree that by engaging in 
      activities with or involving each other as described above, they are 
      participating in transactions involving interstate commerce. This 
      Arbitration Program shall be administered and construed in accordance 
      with the Federal Arbitration Act, other applicable Federal law, and to 
      the extent inapplicable or unenforceable, other applicable law providing 
      for arbitration. If there is any inconsistency between the terms hereof 
      and any governing rules or statutes, the terms hereof shall control. This 
      Arbitration Program constitutes the entire agreement of the parties and 
      supersedes all prior arrangements and other communications on dispute 
      resolution concerning Disputes relating to the Business Banking Group of 
      Bank. In the event more than one arbitration program entered into by the 
      parties is potentially applicable to a Dispute, the one most directly 
      related to the Documents or transaction that is the subject of the 
      Dispute shall control. The provisions of this Arbitration Program shall 
      survive any termination, amendment, or expiration of the Documents or 
      relationships of the parties.

                                    RECITALS

           WHEREAS, The Telecommunications Act of 1996 was signed into law on
February 8, 1996 (the "Act") and substantially amends the Communications Act of
1934; and

           WHEREAS, the Act places certain duties and obligations upon, and
grants certain rights to, Telecommunications Carriers; and

           WHEREAS, PACIFIC is an Incumbent Local Exchange Carrier; and

           WHEREAS, PACIFIC is willing to sell unbundled Network Elements and
Ancillary Functions and additional features, as well as services for resale, on
the terms and subject to the conditions of this Agreement; and

           WHEREAS, CLEC is a Telecommunications Carrier and has requested that
PACIFIC negotiate an Agreement with CLEC for the provision of interconnection,
unbundled Network Elements (including Ancillary Functions and additional
features), and services pursuant to the Act and in conformance with PACIFIC's

           WHEREAS, the Parties have arrived at this Agreement through voluntary

                            DEFINITIONS AND ACRONYMS

           For purposes of this Agreement, certain terms have been defined in
Attachment 1 and elsewhere in this Agreement to encompass meanings that may
differ from, or be in addition to, the normal connotation of the defined word.
Unless the context clearly indicates otherwise, any term defined or used in the
singular shall include the plural. The words "shall" and "will" are used
interchangeably throughout this Agreement and the use of either connotes a
mandatory requirement. The use of one or the other shall not mean a different
degree of right or obligation for either Party. A defined word intended to
convey its special meaning is capitalized when used. Other terms that are
capitalized, and not defined in this Agreement, shall have the meaning

                          GENERAL TERMS AND CONDITIONS

1.      RESERVATION OF RIGHTS TO APPEAL OR PETITION FOR RECONSIDERATION

        1.1.    The filing of this arbitrated Agreement with the Commission in
                accordance with Decision No. 96-12-034 dated December 9,1996
                ("Decision") In the Matter of the Petition of AT&T
                Communications of California, Inc. for Arbitration Pursuant to
                Section 252 of the Telecommunications Act of 1996 to Establish
                an Interconnection Agreement with Pacific Bell, Application
                96-08-040 (Filed August 20,1996) does not in any way constitute
                a waiver by either CLEC or PACIFIC of any right which either
                Party may have to appeal or to petition the Commission for
                reconsideration of any determination contained in the Decision,
                or to seek modification of any language of the Agreement which
                was included (or excluded) due to mistake or clear inadvertence
                caused by the limited amount of time given to prepare this
                Agreement under the Commission's rules.

2.      PROVISION OF LOCAL SERVICE AND UNBUNDLED ELEMENTS

        2.1.    This Agreement and its Attachments are subject to the Act,
                regulations thereunder and relevant FCC and Commission decisions
                in effect on the Effective Date of this Agreement. The effect on
                this Agreement of changes in the Act, regulations thereunder and
                relevant FCC and Commission decisions is set forth in Section 9
                of this Agreement.

        2.2.    This Agreement, which consists of this statement of General
                Terms and Conditions, and Attachments 1 through 18, inclusive,
                sets forth the terms, conditions and prices under which PACIFIC
                agrees to provide to CLEC (a) services for resale (hereinafter
                referred to as "Local Services") and (b) certain unbundled
                Network Elements, Ancillary Functions and additional features
                and (c) other services or combinations of such Local Services,
                Network Elements, Ancillary Functions and other services
                ("Combinations") for CLEC's own use or for resale to others, and
                for purposes of offering telecommunications services of any
                kind. This Agreement also sets forth the terms and conditions
                for the interconnection of CLEC's network to PACIFIC's network
                and the reciprocal compensation for the transport and
                termination of telecommunications traffic. Unless otherwise
                provided in this Agreement, and except where not technically
                feasible in a given area, PACIFIC will perform all of its
                obligations hereunder throughout its entire service area,
                provided, however, that PACIFIC is not required, except at
                CLEC's request pursuant to Section 1.6 of Attachment 6, to
                install new or improved facilities in areas where they do not
                currently exist.

                                                                               3


        2.3.    Subject to this Agreement and its Attachments, the Network
                Elements, Ancillary Functions, Combinations, Local Services, or
                other services provided pursuant to this Agreement may be
                connected to other Network Elements, Ancillary Functions,
                Combinations, Local Services, or other services provided by
                PACIFIC or to any Network Elements, Ancillary Functions,
                Combinations, Local Services or other services provided by CLEC
                itself or by any other vendor. Subject to the requirements of
                this Agreement and its Attachments, CLEC may, at any time add,
                delete, relocate or modify the Network Elements, Ancillary
                Functions, Local Services, Combinations or other services
                purchased hereunder.

        2.4.    PACIFIC will not discontinue any unbundled Network Element,
                Ancillary Service or Combination thereof during the term of this
                Agreement without CLEC's consent, except (i) to the extent
                required by network changes or upgrades, in which event PACIFIC
                will comply with the network disclosure requirements stated in
                the Act and FCC regulations thereunder; or (ii) if required by a
                final order of a court, the FCC or the Commission as a result of
                remand or appeal of the FCC's First Interconnection Order. In
                the event such a final order allows but does not require
                discontinuance, PACIFIC may, on thirty (30) days written notice,
                require that such terms be renegotiated, and the Parties shall
                renegotiate in good faith such mutually acceptable new terms as
                may be required or appropriate to reflect the results of such
                action. In the event that such new terms are not renegotiated
                within ninety (90) days after such notice, or if the Parties are
                unable to agree, either Party may submit the matter to the
                Alternative Dispute Resolution Process described in Attachment
                3.

        2.5.    PACIFIC will not withdraw any Local Service without providing
                one-hundred five (105) days advance notice, from the date of
                notice to the date of withdrawal of the service, to CLEC of
                PACIFIC's intent to withdraw the service, inclusive of the time
                required to file and the Commission to consider an advice letter
                to withdraw the service pursuant to General Order 96A. If
                PACIFIC discontinues a Local Service or Combination of Local
                Services, PACIFIC shall either (a) limit the discontinuance to
                new customers and grandfather the service for all CLEC resale
                customers who subscribe to the service as of the date of
                discontinuance; or (b) offer to CLEC for resale an alternative
                service, having substantially similar capabilities and terms and
                conditions.

3.      TERM OF AGREEMENT; TRANSITIONAL SUPPORT

        3.1.    This Agreement shall expire on 12/19/99, and thereafter the
                Agreement shall continue in force and effect unless and until a
                new agreement, addressing all of the terms of this Agreement,
                becomes effective between the Parties. The Parties agree to
                commence negotiations on a new agreement no less than six (6)
                months before the end of the three (3) years after this
                Agreement becomes effective. In the event that such new terms
                are not renegotiated within such six (6) month

                                                                               4


                period, either Party may submit the matter to the Alternative
                Dispute Resolution Process described in Attachment 3.

        3.2.    PACIFIC recognizes that the Network Elements, Ancillary
                Functions, Combinations, Local Services and other services
                provided hereunder are vital to CLEC and must be continued
                without interruption, and that CLEC may itself provide or retain
                another vendor to provide such comparable Network Elements,
                Ancillary Functions, Combinations, Local Services or other
                services. PACIFIC and CLEC agree to cooperate in an orderly and
                efficient transition to CLEC or another vendor. PACIFIC and CLEC
                further agree to cooperate in effecting the orderly transition
                to CLEC or another vendor such that the level and quality of the
                Network Elements, Ancillary Functions, Combinations, Local
                Services, and other services are not degraded and to exercise
                their best efforts to effect an orderly and efficient
                transition. CLEC shall be responsible for coordinating such

        In the performance of their obligations under this Agreement, the
        Parties shall act in good faith and consistently with the intent of the
        Act. Where notice, approval or similar action by a Party is permitted or
        required by any provision of this Agreement (including, without
        limitation, the obligation of the Parties to further negotiate the
        resolution of new or open issues under this Agreement), such action
        shall not be unreasonably delayed, withheld or conditioned.

        network element contained in any agreement to which PACIFIC is a party
        that has been filed and approved by the Commission.

6.      RESPONSIBILITY OF EACH PARTY

        Each Party is an independent contractor, and has and hereby retains the
        right to exercise full control of and supervision over its own
        performance of its obligations under this Agreement and retains full
        control over the employment, direction, compensation and discharge of
        all employees assisting in the performance of such obligations. Each
        Party will be solely responsible for all matters relating to payment of
        such employees, including compliance with social security taxes,
        withholding taxes and all other regulations governing such matters. Each
        Party will be solely responsible for proper handling, storage, transport
        and disposal at its own expense of all (i) substances or materials that
        it or its contractors or agents bring to, create or assume control over
        at Work Locations or, (ii) Waste resulting therefrom or otherwise
        generated in connection with its or its contractors' or agents'
        activities at the Work Locations. Subject to the limitations on
        liability and except as otherwise provided in this Agreement, each Party

        shall be responsible for (i) its own acts and performance of all
        obligations imposed by Applicable Law in connection with its activities,
        legal status and property, real or personal and, (ii) the acts of its
        own affiliates, employees, agents and contractors during the performance
        of that Party's obligations hereunder.

7.      GOVERNMENTAL COMPLIANCE

        CLEC and PACIFIC each shall comply at its own expense with all
        Applicable Law that relates to (i) its obligations under or activities
        in connection with this Agreement; or (ii) its activities undertaken at,
        in connection with or relating to Work Locations. CLEC and PACIFIC each
        agree to indemnify, defend (at the other Party's request) and save
        harmless the other, each of its officers, directors and employees from
        and against any losses, damages, claims, demands, suits, liabilities,
        fines, penalties and expenses (including reasonable attorneys' fees)
        that arise out of or result from (i) its failure or the failure of its
        contractors or agents to so comply or (ii) any activity, duty or status
        of it or its contractors or agents that triggers any legal obligation to
        investigate or remediate environmental contamination. PACIFIC will be
        solely responsible for obtaining from Governmental Authorities, building
        owners, other carriers, and any other persons or entities, all rights
        and privileges (including, but not limited to, space and power), which
        are necessary for PACIFIC to provide the Network Elements, Ancillary
        Functions, Combinations, Local Services and other services pursuant to
        this Agreement. To the extent necessary, CLEC will cooperate with
        PACIFIC in obtaining such rights and privileges.

8.      RESPONSIBILITY FOR ENVIRONMENTAL CONTAMINATION

        8.1.    CLEC shall in no event be liable to PACIFIC for any costs
                whatsoever resulting from the presence or release of any
                environmental hazard that CLEC did not introduce to the affected
                work location, provided that activities of CLEC or its agents
                did not cause or contribute to a release. PACIFIC shall
                indemnify, defend (at CLEC's request) and hold harmless CLEC,
                each of its officers, directors and employees from and against
                any losses, damages, claims, demands, suits, liabilities, fines,
                penalties and expenses (including reasonable attorneys' fees)
                that arise out of or result from (i) any environmental hazard
                that PACIFIC, its contractors or agents introduce to the work
                locations or (ii) the presence or release of any environmental
                hazard for which PACIFIC is responsible under applicable law.

        8.2.    PACIFIC shall in no event be liable to CLEC for any costs
                whatsoever resulting from the presence or release of any
                environmental hazard that PACIFIC did not introduce to the
                affected work location, provided that actions of PACIFIC or its
                agents did not cause or contribute to a release. CLEC shall
                indemnify, defend (at PACIFIC's request) and hold harmless
                PACIFIC, each of its officers, directors and employees from and
                against any losses, damages, claims, demands, suits,
                liabilities, fines, penalties and expenses (including reasonable
                attorneys fees) that arise out of or result from (i) any
                environmental hazard that CLEC, its contractors

                                                                               6


                or agents introduce to the work locations or (ii) the presence
                or release of any environmental hazard for which CLEC is
                responsible under applicable law.

9.      REGULATORY MATTERS

        9.1.    PACIFIC shall be responsible for obtaining and keeping in effect
                all FCC, state regulatory commission, franchise authority and
                other regulatory approvals that may be required in connection
                with the performance of its obligations under this Agreement.
                CLEC shall be responsible for obtaining and keeping in effect
                all FCC, state regulatory commission, franchise authority and
                other regulatory approvals that may be required in connection
                with its obligations under this Agreement, and with its offering
                of services to CLEC Customers contemplated by this Agreement.
                CLEC shall reasonably cooperate with PACIFIC in obtaining and
                maintaining any required approvals for which PACIFIC is
                responsible, and PACIFIC shall reasonably cooperate with CLEC in
                obtaining and maintaining any required approvals for which CLEC
                is responsible.

        9.2.    To the extent that PACIFIC is required by any Governmental
                Authority to file a tariff or make another similar filing in
                connection with the performance of any action that would
                otherwise be governed by this Agreement, the terms of this
                Agreement shall control, unless this Agreement links a term,
                condition or price in this Agreement to a specific tariff, in
                which case the terms of the tariff as modified from time to time
                will apply. If, subsequent to the effective date of any tariff
                incorporated by reference into this Agreement, PACIFIC is
                ordered not to file tariffs with the state regulatory commission
                or the FCC, or is permitted not to file tariffs (and elects not
                to do so), either generally or for specific Network Elements,
                Ancillary Functions, Combinations, Local Services or other
                services provided hereunder, the terms and conditions of such
                tariffs as of the date on which the requirement to file such
                tariffs was lifted shall, to the degree not inconsistent with
                this Agreement, be deemed incorporated in this Agreement by
                reference.

        9.3.    In the event that any final and nonappealable legislative,
                regulatory, judicial or other legal action renders this
                Agreement or any Attachment hereto inoperable, materially
                affects any material terms of this Agreement, or materially
                affects the ability of CLEC or PACIFIC to perform any material
                terms of this Agreement, CLEC or PACIFIC may, on thirty (30)
                days written notice (delivered not later than thirty (30) days
                following the date on which such action has become legally
                binding and has otherwise become final and nonappealable)
                require that such terms be renegotiated, and the Parties shall
                renegotiate in good faith such mutually acceptable new terms as
                may be required. In the event that such new terms are not
                renegotiated within ninety (90) days after such notice, the
                dispute shall be referred to the Alternative Dispute Resolution
                procedures set forth in Section 17 and Attachment 3.

        9.4.    Pursuant to the Decision (at 11-12), unless the Parties
                voluntarily agree otherwise, all terms of this Agreement will be
                subject to modification based on future Commission decisions.

                total of any amounts due and owing by CLEC to PACIFIC under this

        10.3.   No Consequential Damages - NEITHER CLEC NOR PACIFIC SHALL BE
                LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, INCIDENTAL,
                CONSEQUENTIAL, RELIANCE, OR SPECIAL DAMAGES SUFFERED BY SUCH
                OTHER PARTY (INCLUDING WITHOUT LIMITATION DAMAGES FOR HARM TO
                BUSINESS, LOST REVENUES, LOST SAVINGS, OR LOST PROFITS SUFFERED
                BY SUCH OTHER PARTY), REGARDLESS OF THE FORM OF ACTION, WHETHER
                IN CONTRACT, WARRANTY, STRICT LIABILITY, OR TORT, INCLUDING
                WITHOUT LIMITATION NEGLIGENCE OF ANY KIND WHETHER ACTIVE OR
                PASSIVE, AND REGARDLESS OF WHETHER THE PARTIES KNEW OF THE
                POSSIBILITY THAT SUCH DAMAGES COULD RESULT. EACH PARTY HEREBY
                RELEASES THE OTHER PARTY (AND SUCH OTHER PARTY'S SUBSIDIARIES
                AND AFFILIATES, AND THEIR RESPECTIVE OFFICERS, DIRECTORS;
                EMPLOYEES AND AGENTS) FROM ANY SUCH CLAIM. NOTHING CONTAINED IN
                THIS SECTION 10 SHALL LIMIT PACIFIC'S OR CLEC'S LIABILITY TO THE

                NEGLIGENCE); (ii) BODILY INJURY, DEATH OR DAMAGE TO TANGIBLE
                REAL OR TANGIBLE PERSONAL PROPERTY PROXIMATELY CAUSED BY

                RESPECTIVE AGENTS SUBCONTRACTORS OR EMPLOYEES, NOR SHALL
                ANYTHING CONTAINED IN THIS SECTION 10 LIMIT THE PARTIES'
                INDEMNIFICATION OBLIGATIONS, AS SPECIFIED BELOW. FOR PURPOSES OF
                THIS SECTION 10, AMOUNTS DUE AND OWING TO EITHER PARTY PURSUANT
                TO ATTACHMENT 17 SHALL NOT BE CONSIDERED TO BE INDIRECT,
                INCIDENTAL, CONSEQUENTIAL, RELIANCE, OR SPECIAL DAMAGES.

        10.4.   Obligation to Indemnify - Each Party shall, and hereby agrees
                to, defend at the other's request, indemnify and hold harmless
                the other Party and each of its officers, directors, employees
                and agents (each, an "Indemnitee") against and in respect of any
                loss, debt, liability, damage, obligation, claim, demand,
                judgment or settlement of any nature or kind, known or unknown,
                liquidated or unliquidated, including without limitation all
                reasonable costs and expenses incurred (legal, accounting or
                otherwise) (collectively, "Damages") arising out of, resulting
                from or based upon any pending or threatened claim, action,
                proceeding or suit by any third party (a "Claim") (i) alleging
                any breach of any representation, warranty or covenant made by
                such indemnifying Party (the "Indemnifying Party") in this
                Agreement, (ii) based upon injuries or damage to any person or
                property or the environment arising out of or in connection with
                this Agreement that are the result of the Indemnifying Party's
                actions, breach of Applicable Law, or status or the actions,
                breach of Applicable Law, or status of its employees, agents and
                subcontractors, or (iii) for actual or alleged infringement of
                any patent, copyright, trademark, service mark, trade name,
                trade dress, trade secret or any other intellectual property
                right, now known or later developed (referred to as
                "Intellectual Property Rights") to the extent that such claim or
                action arises from the Indemnifying Party's or the Indemnifying
                Party's customer's use of the Network Elements, Ancillary
                Functions, Combinations, Local Services or other services
                provided under this Agreement.

        10.5.   Obligation to Defend; Notice; Co-operation - Whenever a Claim
                shall arise for indemnification under Section 10.4, the relevant
                Indemnitee, as appropriate, shall promptly notify the
                Indemnifying Party and request the Indemnifying Party to defend
                the same. Failure to so notify the Indemnifying Party shall not
                relieve the Indemnifying Party of any liability that the
                Indemnifying Party might have, except to the extent that such
                failure prejudices the Indemnifying Party's ability to defend
                such Claim. The Indemnifying Party shall have the right to
                defend against such liability or assertion in which event the
                Indemnifying Party shall give written notice to the Indemnitee
                of acceptance of the defense of such Claim and the identity of
                counsel selected by the Indemnifying Party. Except as set forth
                below, such notice to the relevant Indemnitee shall give the
                Indemnifying Party full authority to defend, adjust, compromise
                or settle such Claim with respect to which such notice shall
                have been given, except to the extent that any compromise or
                settlement shall prejudice the Intellectual Property Rights of
                the relevant Indemnitees. The Indemnifying Party shall consult
                with the relevant Indemnitee prior to any compromise or
                settlement that would affect the Intellectual Property Rights or
                other rights of any Indemnitee, and the relevant Indemnitee
                shall have the right to refuse such compromise or settlement
                and, at the refusing Party's or refusing Parties' cost, to take
                over such defense, provided that in such event the Indemnifying
                Party shall not be responsible for, nor shall it be obligated to
                indemnify the relevant Indemnitee against, any cost or liability
                in excess of such refused compromise or settlement. With respect
                to any defense accepted by the Indemnifying Party, the relevant
                Indemnitee shall be entitled to participate with


<PAGE>   12
                                                                               9


                the Indemnifying Party in such defense if the Claim requests
                equitable relief or other relief that could affect the rights of
                the Indemnitee and also shall be entitled to employ separate
                counsel for such defense at such Indemnitee's expense. In the
                event the Indemnifying Party does not accept the defense of any
                indemnified Claim as provided above, the relevant Indemnitee
                shall have the right to employ counsel for such defense at the
                expense of the Indemnifying Party. Each Party agrees to
                cooperate and to cause its employees and agents to cooperate
                with the other Party in the defense of any such Claim and the
                relevant records of each Party shall be available to the other
                Party with respect to any such defense.

11.     AUDITS AND INSPECTIONS

        11.1.   Subject to PACIFIC's reasonable security requirements and except
                as may be otherwise specifically provided in this Agreement,
                CLEC may audit PACIFIC's books, records, and other documents
                once in each Contract Year for the purpose of evaluating the
                accuracy of PACIFIC's billing and invoicing for services
                provided by PACIFIC to CLEC hereunder. CLEC may employ other
                persons or firms for this purpose. Such audit shall take place
                at a time and place agreed on by the Parties no later than
                thirty (30) days after notice thereof to PACIFIC.

        11.2.   Subject to CLEC's reasonable security requirements and except as
                may be otherwise specifically provided in this Agreement,
                PACIFIC may audit CLEC's books, records, and other documents
                once in each Contract Year for the purpose of evaluating the
                accuracy of CLEC's billing and invoicing for services provided
                by CLEC to PACIFIC hereunder. PACIFIC may employ other persons
                or firms for this purpose. Such audit shall take place at a time
                and place agreed on by the Parties no later than thirty (30)
                days after notice thereof to CLEC.

        11.3.   Each Party shall promptly correct any billing or invoicing
                errors that are revealed in an audit, including making refund of
                any overpayment in the form of a credit, or payment of any under
                payment in the form of a debit, on the invoice for the first
                full billing cycle after the Parties have agreed upon the
                accuracy of the audit results. Any disputes concerning audit
                results shall be resolved pursuant to the Alternate Dispute
                Resolution procedures described in Attachment 3.

        11.4.   Each Party shall cooperate fully in any such audit, providing
                reasonable access to any and all appropriate employees and
                books, records and other documents reasonably necessary to
                assess the accuracy of each Party's billing and invoicing.

        11.5.   Either Party may audit the other Party's books, records and
                documents more than once during any Contract Year if the
                previous audit found previously uncorrected net variances or
                errors in invoices in the other Party's favor with an aggregate
                value of at least three percent (3%) of the amounts payable by
                the Party being audited under this Agreement during the period
                covered by the audit.

        11.6.   Audits shall be at the requesting Party's expense, subject to
                reimbursement by the audited Party in the event that an audit
                finds an adjustment in the charges or in any invoice paid or
                payable by the requesting Party hereunder by an amount that is,
                on an annualized basis, greater than three percent (3%) of the
                aggregate charges to the requesting Party under this Agreement
                during the period covered by the audit.

        11.7.   Upon (i) the discovery by a Party of overcharges not previously
                reimbursed to the other Party or (ii) the resolution of disputed
                audits, the audited Party shall promptly reimburse the
                requesting Party the amount of any overpayment, plus interest at
                the prime rate compounded daily for the number of days from the
                date of overpayment to and including the date that payment is
                actually made. In no event, however, shall interest be assessed
                on any previously assessed or accrued late payment charges.

        11.8.   Upon (i) the discovery by either Party of underpayments not
                previously paid to the other Party, or (ii) the resolution of
                disputed audits, the audited Party shall promptly pay the other
                Party the amount of any underpayment, plus interest at the prime
                rate compounded daily from the date of underpayment to and
                including the date that payment is actually made.

        11.9.   Subject to PACIFIC's reasonable security requirements and except
                as may be otherwise specifically provided in this Agreement,
                CLEC shall have the following audit rights in addition to the
                financial audit rights provided above: (a) if CLEC has a
                reasonable basis to believe that an audit is required to confirm
                PACIFIC's compliance with the Act or this Agreement, CLEC may
                inspect once, in each Contract Year, PACIFIC's books, records,
                and other documents relevant to the Network Elements, Ancillary
                Functions, Combinations, Local Services, or other services
                provided to CLEC for the purpose of evaluating PACIFIC's
                compliance with the terms and conditions of this Agreement; and
                (b) CLEC shall have the audit rights specified in Attachments 17
                and 18. CLEC employees may conduct audits pursuant to this
                Section 11.9, unless PACIFIC reasonably maintains that the
                books, records and other documents relating to CLEC are
                impossible or impractical to segregate from documents containing
                proprietary information of other parties, in which case, the
                audit shall be conducted by a mutually designated third Party
                auditor, with the expense shared equally by the Parties,
                provided, however, that (a) if the auditor finds that PACIFIC
                has complied with the Act or this Agreement, CLEC shall pay for
                the audit; and (b) if the auditor finds that PACIFIC has not
                complied with the Act or this Agreement, PACIFIC shall pay for
                the audit.

12.     SERVICE PERFORMANCE MEASURES AND RELATED REMEDIES

        12.1.   Remedies. The remedies set forth in Attachment 17 shall apply
                when default has occurred as defined in this Agreement, and,
                where appropriate, default notice has


<PAGE>   14
                                                                              11


                been given. Payment of remedies shall be in the nature of
                liquidated damages to the non-defaulting Party, and shall be in
                lieu of all other damages related to the default, including
                without limitation liability imposed by tariff for the same
                default. Where more than one performance category is subject to
                the remedy, a remedy payment for each category will be made by
                the defaulting Party to the non-defaulting Party, except where
                remedies involve waiver of non-recurring charges, the charge
                will only be waived once per affected service order. Remedies
                for comparative measures will be paid only for those defaulting
                performance areas for the number of provisioning and maintenance
                items that would restore service levels to parity based on the
                measured performance for the same class of service, at the same
                time in the same geographic area.

        12.2.   In order that both Parties may have the opportunity to evaluate
                the forecasting, operational processes and service levels
                provided under the Agreement, remedies will not be applied in
                the first six months from the Effective Date of the Agreement.
                Prior to the commencement of remedies, each Party will measure
                performance and, as mutually agreed, will change measurements,
                objectives and remedy limits when actual performance indicates
                that any of the measurements, objectives or remedy limits are
                ineffective or inappropriate for the service or Network Element
                being provided.

        12.3.   The Parties may amend, modify, delete or add remedies by mutual
                agreement and modification of Attachment 17.

13.     UNCOLLECTIBLE OR UNBILLABLE REVENUES

        13.1.   Uncollectible or unbillabel revenues resulting from, but not
                confined to, provisioning, maintenance, or signal network
                routing errors shall be the responsibility of the Party causing
                such error.

14.     CUSTOMER CREDIT HISTORY

        CLEC and PACIFIC agree to make available to the Centralized Credit Check
        System (CCCS) on a timely basis the following customer payment history
        components for each person or entity that applies for local or intraLATA
        toll Telecommunications Service(s) from either carrier, and for each
        unpaid closed account. Such information shall be provided on the
        condition that the CCCS will only make such information available to the
        carrier to which the person or entity in question has applied for
        telephone service when CCCS has unpaid closed account information for
        that applicant.

        Customer's full name, surname, given name, middle name or initial;
        Service address, when service was/is provided; 
        Mailing address, where bills are sent; 
        Current telephone number; 
        Applicant's previous phone number; if any; 
        Spouse's name, if applicable;


<PAGE>   15
                                                                              12


        Valid identifying number(s) for customer and/or spouse, e.g. 
        Social Security Number, Driver's License, etc.; 
        Specific Data regarding accounts that have left an unpaid debt with the 
        utility; and 
        Payments and adjustments on unpaid accounts to update current balance 
        due information.

15.     FORCE MAJEURE

        15.1.   Except as otherwise specifically provided in this Agreement,
                neither Party shall be liable for any delay or failure in
                performance of any part of this Agreement caused by a Force
                Majeure condition, including acts of the United States of
                America or any state, territory or political subdivision
                thereof, acts of God or a public enemy, fires, floods, disputes,
                freight embargoes, earthquakes, volcanic actions, wars, civil
                disturbances, or other causes beyond the reasonable control of
                the Party claiming excusable delay or other failure to perform.
                Provided, Force Majeure shall not include acts of any
                Governmental Authority relating to environmental, health or
                safety conditions at Work Locations. If any Force Majeure
                condition occurs, the Party whose performance fails or is
                delayed because of such Force Majeure condition shall give
                prompt notice to the other Party, and upon cessation of such
                Force Majeure condition, shall give like notice and commence
                performance hereunder as promptly as reasonably practicable.

        15.2.   Notwithstanding subsection 15.1, preceding, no delay or other
                failure to perform shall be excused pursuant to this Section:
                (i) by the acts or omissions of a Party's subcontractors,
                material men, suppliers or other third persons providing
                products or services to such Party unless such acts or omissions
                are themselves the product of a Force Majeure condition, (ii) if
                the delay or failure relates to environmental, health or safety
                conditions at Work Locations and, (iii) unless such delay or
                failure and the consequences thereof are beyond the control and
                without the fault or negligence of the Party claiming excusable
                delay or other failure to perform.

16.     CERTAIN STATE AND LOCAL TAXES

        Any state or local excise, sales, or use taxes (excluding any taxes
        levied on income) resulting from the performance of this Agreement shall
        be borne by the Party upon which the obligation for payment is imposed
        under applicable law, even if the obligation to collect and remit such
        taxes is placed upon the other Party, provided, however, that the other
        Party has not acted in a manner that has materially impaired the ability
        of the liable Party to contest the tax or the amount of the tax (and
        interest and penalties, etc.) regardless of whether the impairment was
        foreseeable. If the other Party has materially impaired the ability of
        the liable Party to contest the tax or the amount of the tax, the Party
        causing the impairment shall be liable for the tax (interest and
        penalties, etc.) caused by the Party's impairment. Any such taxes shall
        be shown as separate items on applicable billing documents between the
        Parties. The Party so obligated to pay any such taxes may contest the
        same in good faith, at its own expense, and shall be entitled to the
        benefit of any refund or recovery, provided that such Party shall not
        permit any lien to 


<PAGE>   16
                                                                              13


        exist on any asset of the other Party by reason of the contest. The
        Party obligated to collect and remit shall cooperate in any such contest
        by the other Party;

17.     ALTERNATIVE DISPUTE RESOLUTION

        All disputes, claims or disagreements (collectively "Disputes") arising
        under or related to this Agreement or the breach hereof, except those
        arising pursuant to Attachment 13, Connectivity Billing, shall be
        resolved according to the procedures set forth in Attachment 3. Disputes
        involving matters subject to the Connectivity Billing provisions
        contained in Attachment 13, shall be resolved in accordance with the
        Billing Disputes section of Attachment 13. In no event shall the Parties
        permit the pendency of a Dispute to disrupt service to any CLEC Customer
        contemplated by this Agreement. The foregoing notwithstanding, neither
        this Section 17 nor Attachment 3 shall be construed to prevent either
        Party from (a) invoking a remedy required or permitted by the Act or FCC
        regulations thereunder or (b) seeking and obtaining temporary equitable
        remedies, including temporary restraining orders. A request by a Party
        to a court or a regulatory authority for interim measures or equitable
        relief shall not be deemed a waiver of the obligation to comply with
        Attachment 3.

18.     NOTICES

        delivered under this Agreement shall be in hard-copy writing (unless

19.     CONFIDENTIALITY AND PROPRIETARY INFORMATION

        19.1.   For the purposes of this Agreement, "Confidential Information"
                means confidential or proprietary technical or business
                Information given by the Discloser to the Recipient. All
                information which is disclosed by one Party to the other in
                connection with this Agreement shall automatically be deemed
                proprietary to the Discloser and subject to this Agreement,
                unless otherwise confirmed in writing by the Discloser. In
                addition, by way of example and not limitation, all orders for
                Network Elements Ancillary Functions, Combinations, Local
                Services or other services placed by CLEC pursuant to this
                Agreement, and information that would constitute Customer
                Proprietary Network Information of CLEC Customers pursuant to
                the Act and the rules and regulations of the FCC, and Recorded
                Usage Data as described in Attachment 14, whether disclosed by
                CLEC to PACIFIC or otherwise acquired by PACIFIC in the course
                of the performance of this Agreement, shall be deemed
                Confidential Information of CLEC for all purposes under this
                Agreement.

        19.2.   For a period of five (5) years from the receipt of Confidential
                Information from the Discloser, except as otherwise specified in
                this Agreement, the Recipient agrees (a) to use it only for the
                purpose of performing under this Agreement; (b) to hold it in
                confidence and disclose it to no one other than its employees
                having a need to know for the purpose of performing under this
                Agreement; and (c) to safeguard it from unauthorized use or
                disclosure with at least the same degree of care with which the
                Recipient safeguards its own Confidential Information. If the
                Recipient wishes to disclose the Discloser's Confidential
                Information to a third party agent or consultant, such
                disclosure must be mutually agreed to in writing by the Parties
                to this Agreement, and the agent or consultant must have
                executed a written agreement of non-disclosure and non-use
                comparable in scope to the terms of this Section.

        19.3.   The Recipient may make copies of Confidential Information only
                as reasonably necessary to perform its obligations under this
                Agreement. All such copies shall 

<PAGE>   18
                                                                              15


                bear the same copyright and proprietary rights notices as are
                contained on the original.

        19.4.   The Recipient agrees to return all Confidential Information in
                tangible form received from the Discloser, including any copies
                made by the Recipient, within thirty (30) days after a written
                request is delivered to the Recipient, or to destroy all such
                Confidential Information. except for Confidential Information
                that the Recipient reasonably requires to perform its
                obligations under this Agreement. If either Party loses or makes
                an unauthorized disclosure of the other Party's Confidential
                Information, it shall notify such other Party immediately and
                use reasonable efforts to retrieve the lost or wrongfully
                disclosed information.

        19.5.   The Recipient shall have no obligation to safeguard Confidential
                Information: (a) which was in the possession of the Recipient
                free of restriction prior to its receipt from the Discloser; (b)
                after it becomes publicly known or available through no breach
                of this Agreement by the Recipient; (c) after it is rightfully
                acquired by the Recipient free of restrictions on its
                disclosure; or (d) after it is independently developed by
                personnel of the Recipient to whom the Discloser's Confidential
                Information had not been previously disclosed. In addition,
                either Party shall have the right to disclose Confidential
                Information to any mediator, arbitrator, state or federal
                regulatory body, the Department of Justice or any court in the
                conduct of any mediation, arbitration or approval of this
                Agreement or in any proceedings concerning the provision of
                interLATA services by PACIFIC. Additionally, the Recipient may
                disclose Confidential Information if so required by law, a
                court, or governmental agency, so long as the Discloser has been
                notified of the requirement promptly after the Recipient becomes
                aware of the intended disclosure, and so long as the Recipient
                undertakes all lawful measures to avoid disclosing such
                information until Discloser has had reasonable time to seek a
                protective order that covers the Confidential Information to be
                disclosed.

        19.6.   Each Party's obligations to safeguard Confidential Information
                disclosed prior to expiration or termination of this Agreement
                shall survive such expiration or termination.

        19.7.   Except as otherwise expressly provided elsewhere in this
                Agreement, no license is hereby granted under any patent,
                trademark, or copyright, nor is any such license implied, solely
                by virtue of the disclosure of any Confidential Information.

        19.8.   Each Party agrees that the Discloser would be irreparably
                injured by a breach of this Agreement by the Recipient or its
                representatives and that the Discloser shall be entitled to seek
                equitable relief, including injunctive relief and specific
                performance, in the event of any breach of the provisions of
                this Agreement. Such remedies shall not be deemed to be the
                exclusive remedies for a breach of this Agreement, but shall be
                in addition to all other remedies available at law or in equity.

        19.9.   Nothing in this Section 19 shall prevent PACIFIC from using
                Recorded Usage Data for the limited purpose of network planning
                and management.

20.     BRANDING

        20.1.   Services offered by CLEC that incorporate Network Elements,
                Ancillary Functions or Combinations made available to CLEC
                pursuant to this Agreement, and Local Services that CLEC offers
                for resale shall be branded as stated in the Attachments to this
                Agreement. In no event shall PACIFIC personnel installing or
                repairing CLEC Local Service, Network Elements, or Combinations

                effect, and will include the most recent version or edition

                waiver or consent is claimed or by the designated representative

                of a Party strictly to enforce any term, right or condition of

                Agreement is held to be invalid or unenforceable for any reason,
                such invalidity or unenforceability shall not invalidate the
                entire Agreement, unless such construction would be
                unreasonable. The Agreement shall be construed as if it did not
                contain the invalid or unenforceable provision or provisions,
                and the rights and obligations of each Party shall be construed
                and enforced accordingly; provided, however, that in the event
                such invalid or unenforceable provision or provisions are
                essential elements of this Agreement and substantially impair
                the rights or obligations of either Party, the Parties shall
                promptly negotiate a replacement provision or provisions.

105.       "Transit Rate" is the rate that applies to local and toll calls sent
           between a LEC and a CLC destined for a third-party LEC or CLC.

106.       "Trunk-Side" refers to a Central Office switch connection that is
           capable of, and has been programmed to treat the circuit as
           connecting to another switching entity, for example, another Central
           Office switch. Trunk-Side connections offer those transmission and
           signaling features appropriate for the connection of switching
           entities and cannot be used for the direct connection of ordinary
           telephone station sets.

           materials which are intended to be discarded, scrapped, or recycled,
           associated with activities CLEC or PACIFIC or their respective
           contractors or agents perform at Work Locations. It shall be presumed
           that all substances or materials associated with such activities,
           that are not in use or incorporated into structures (including
           without limitation damaged components or tools, leftovers,
           containers, garbage, scrap, residues or by products), except for
           substances and materials that CLEC, PACIFIC or their respective
           contractors or agents intend to use in their original form in
           connection with similar activities, are Waste. "Waste" shall not
           include substances, materials or components incorporated into

                         ALTERNATIVE DISPUTE RESOLUTION

1.      PURPOSE

        economical, and equitable resolution of disputes between PACIFIC and
        CLEC arising under this Agreement.

2.      EXCLUSIVE REMEDY

2.1     Except for disputes or matters (i) for which the total value of the
        amount in controversy exceeds Twenty Five Million Dollars ($25,000,000),
        (ii) for which this Agreement or the Telecommunications Act of 1996
        specifies a particular remedy or procedure, (iii) for which a Party
        seeks injunctive relief and/or specific performance in any Court of
        competent jurisdiction, or (iv) which are covered by the Billing
        Disputes provisions contained in Attachment 13 (Connectivity Billing and
        Recording), informal resolution and arbitration under the procedures
        provided herein shall be the exclusive remedy for all disputes between
        PACIFIC and CLEC arising out of this Agreement or its breach. PACIFIC
        and CLEC agree not to resort to any court, agency, or private group with
        respect to such disputes except in accordance with this Attachment.

2.1.1   If, for any reason, certain claims or disputes are deemed to be
        nonarbitrable, the non-arbitrability of those claims or disputes shall
        in no way affect the arbitrability of any other claims or disputes.

2.1.2   If, for any reason, the FCC or any other federal or state regulatory
        agency exercises jurisdiction over and decides any dispute related to
        this Agreement, or to the Act, or to any tariff and, as a result, a
        claim is adjudicated in both an agency proceeding and an arbitration
        proceeding under this Attachment 3, the following provisions shall
        apply:

2.1.2.1 To the extent required by law, the agency ruling shall be binding upon
        the parties and shall take precedence over any contrary ruling of the
        arbitrator for those matters within the jurisdiction and authority of
        such agency.

2.1.2.2 The arbitration ruling rendered pursuant to this Attachment 3 shall be
        binding upon the parties for purposes of establishing their respective
        contractual rights and obligations under this Agreement.

3.      INFORMAL RESOLUTION OF DISPUTES

3.1     Prior to initiating an arbitration pursuant to the American Arbitration
        Association ("AAA") rules, as described below, the parties to this
        Agreement shall submit any dispute between PACIFIC and CLEC for
        resolution to an Inter-Company Review Board consisting of one
        representative from CLEC at the Director-or-above level and one
        representative from PACIFIC at the Vice-President-or-above level (or at
        such lower level as each Party may designate).

        inform the Arbitrator of any statement or other action of a Party in
        connection with negotiations between the Parties pursuant to the
        Informal Resolution of Disputes provision of this Attachment 3.

4.      INITIATION OF AN ARBITRATION

        If the Inter-Company Review Board is unable to resolve the dispute
        within 30 days (or such longer period as agreed to in writing by the
        Parties) of such submission, and the Parties have not otherwise entered
        into a settlement of their dispute, either Party may initiate an
        arbitration in accordance with the AAA rules.

5.      GOVERNING RULES FOR ARBITRATION

        The rules set forth below and the rules of the AAA shall govern all
        arbitration proceedings initiated pursuant to this Attachment; however,
        such arbitration proceedings shall not be conducted under the auspices
        of the AAA unless the Parties mutually agree. Where any of the rules set
        forth herein conflict with the rules of the AAA, the rules set forth in
        this Attachment shall prevail.

        Parties may mutually agree to in writing).

        resignation, removal, or inability, unless a different time period is
        mutually agreed upon in writing by the Parties. Any matters pending
        before the Arbitrator at the time he or she resigns, is removed, or
        becomes unable to discharge his or her duties, will be assigned to the
        replacement Arbitrator as soon as the replacement Arbitrator is
        appointed.

        time limit set forth in Section 6.2 of this Attachment 3, or a
        replacement Arbitrator within the time limit set forth in Section 6.3 of
        this Attachment 3, either Party may apply to AAA for appointment of such
        Arbitrator. Prior to filing an application with the AAA, the Party

        witnesses pursuant to the United States Arbitration Act, hold hearings,
        issue decisions, and maintain a record of proceedings. The Arbitrator
        shall have the power to award any remedy or relief that a court with
        jurisdiction over this Agreement could order or grant, including,
        without limitation, the awarding of damages, pre-judgement interest, or
        imposition of sanctions for abuse or frustration of the arbitration
        process, except that the Arbitrator may not award injunctive relief,
        punitive damages or any remedy rendered unavailable to the Parties
        pursuant to Section 10.3 of this Agreement.

7.2     The Arbitrator shall not have the authority to limit, expand, or
        otherwise modify the terms of this Agreement.

        There shall be no discovery except for the exchange of documents deemed
        necessary by the Arbitrator to an understanding and determination of the
        dispute. PACIFIC and CLEC shall attempt, in good faith, to agree on a
        plan for document discovery. Should they fail to agree, either PACIFIC
        or CLEC may request a joint meeting or conference call with the
        Arbitrator. The Arbitrator shall resolve any disputes between PACIFIC
        and CLEC, and such resolution with respect to the need, scope, manner,
        and timing of discovery shall be final and binding.

9.      PRIVILEGES

        Although conformity to certain legal rules of evidence may not be
        necessary in connection with arbitrations initiated pursuant to this
        Attachment, the Arbitrator shall, in all cases, apply the
        attorney-client privilege and the work product immunity doctrine.

        San Francisco, California.

11.     DECISION

        shall be in writing unless the Parties mutually agree in writing to
        waive the requirement of a written opinion. Judgment upon the award
        rendered by the Arbitrator may be entered in any court having
        jurisdiction thereof. Either Party may apply to the United States

12      FEES

12.1    The Arbitrator shall, in his or her discretion, apportion the
        Arbitrator's fees and expenses to reflect the relative success of each
        Party. In accordance with Section 3.2. of this Attachment 3, in the
        event that the Parties settle a dispute before the Arbitrator reaches a
        decision with respect to that dispute, the Settlement Agreement must
        specify how the Arbitrator's fees for the particular proceeding will be
        apportioned.

12.2    In an action to enforce or confirm a decision of the Arbitrator, the
        prevailing Party shall be entitled to its reasonable attorneys' fees,
        costs, and expenses necessarily incurred in the enforcement proceedings
        without regard to the local rules of the district in which the suit is
        brought.

13.     CONFIDENTIALITY

13.1    PACIFIC, CLEC, and the Arbitrator will treat the arbitration proceeding,
        including the hearings and conferences, discovery, or other related
        events, as confidential, except as necessary in connection with a
        judicial challenge to, or enforcement of, an award, or unless otherwise
        required by an order or lawful process of a court or governmental body.

13.2    In order to maintain the privacy of all arbitration conferences and
        hearings, the Arbitrator shall have the power to require the exclusion
        of any person, other than a Party, counsel thereto, or other essential
        persons.

13.3    To the extent that any information or materials disclosed in the course
        of an arbitration proceeding contains proprietary or confidential
        information (Confidentiality Information) of either Party, it shall be
        safeguarded in accordance with Section 19 of the Agreement. However,
        nothing in Section 19 of the Agreement shall be construed to prevent
        either Party from disclosing the other Party's Confidential Information
        to the Arbitrator in connection with or in anticipation of an
        arbitration proceeding. In addition, the Arbitrator may issue orders to
        protect the confidentiality of proprietary information, trade secrets,
        or other sensitive information.

14.     SERVICE OF PROCESS

        Service may be made by submitting one copy of all pleadings and
        attachments and any other documents requiring service to each Party and
        one copy to the Arbitrator. Service shall be deemed made (i) upon
        receipt if delivered by hand; (ii) the next business day if sent by
        overnight courier service; or (iii) upon confirmed receipt if
        transmitted by facsimile. If service is by facsimile, a copy shall be
        sent the same day by hand delivery or overnight courier service.

14.1    Service by CLEC to PACIFIC and by PACIFIC to CLEC at the address
        designated for delivery of notices in this Agreement shall be deemed to
        be service to PACIFIC or CLEC, respectfully.

                         DIRECTORY LISTING REQUIREMENTS



1.      GENERAL

        PACIFIC shall make available to CLEC, for CLEC Customers,
        nondiscriminatory access to its telephone number and address directory
        listings ("Directory Listings"), under the following terms and
        conditions:

2.      WHITE AND YELLOW PAGE LISTINGS

        PACIFIC publishes and distributes white pages directories through its
        wholly owned subsidiary PBD, as its agent for the white pages. PBD also
        publishes and distributes yellow pages directories. With respect to
        those directories, upon receipt of the necessary customer information
        from CLEC, PACIFIC will include, at no charge, a standard, basic listing
        (i) of CLEC's residence customers in the appropriate white pages
        directory and, (ii) of CLEC's business customers in the appropriate
        white pages and yellow pages directories. Additionally, CLEC's customers
        each will have delivered to them at no charge one copy of appropriate
        white and yellow pages directories. Where an CLEC Customer has two
        numbers for a line due to the implementation of interim Local Number
        Portability; the second number shall be considered part of the one White
        Pages basic listing. PACIFIC shall permit CLEC Customers the option of
        not having a published White Pages listing; this option will be provided
        at the same price PACIFIC charges its end user customers for the same
        option. PACIFIC shall include in its master subscriber list database all
        Subscriber Listing Information for CLEC Customers; PACIFIC's use of CLEC
        Subscriber Listing information is subject to Section 6 of this
        Attachment 4.

3.      DIRECTORIES

3.1     Upon receipt of the necessary customer information from CLEC, PACIFIC
        shall deliver Directory Listings in book form ("Telephone Directories")
        to each of CLEC's exchange service Customers with or without charge on
        the same basis that it delivers Telephone Directories to its own
        customers with or without charge. There is no limit on the total number
        of directories that may be delivered by PACIFIC. Timing of such delivery
        and the determination of which Telephone Directories shall be delivered
        (whether by customer address, NPNNXX or other criteria), and the number
        of Telephone Directories to be provided per customer, shall be provided
        under the same terms that PACIFIC delivers Telephone Directories to its
        own local service customers.

3.2     PACIFIC shall make available recycling services for Telephone
        Directories to CLEC Customers under the same terms and conditions that
        PACIFIC makes such services available to its own local service
        customers.

                                                                     Page 2 of 3



4.      DIRECTORY LISTING CRITERIA

        The general terms relating to white and yellow page listings and
        non-published listings are set forth in PACIFIC's Schedule Cal.P.U.C.
        No. 175T, Sec. 93. Information relating to paid advertising, publication
        schedules and coverage of specific directories may be obtained by CLEC
        from PBD. PACIFIC's listing handbook will be available in the CLC
        Handbook. PACIFIC will update the CLC Handbook as product offerings or
        product process changes are made. The changes will be available
        automatically to CLEC through LI-OFFICE. Until such time as PACIFIC's
        Listings Handbook is available through LI-OFFICE, PACIFIC shall provide
        an updated paper copy of the CLC Listings Handbook on a quarterly basis
        starting not later than ten (10) days after the Effective Date of this
        Agreement. This Listing Handbook update will include all changes to the
        directory listing criteria.

5.      CUSTOMER INFORMATION LISTING

        In areas where CLEC provides (or plans to provide service within the
        next 12 months) exchange service, PACIFIC shall include, in the Customer
        Guide section of each Telephone Directory, not less than one full page
        of information about CLEC services, including addresses and telephone
        numbers for CLEC Customer service. A maximum of two pages will be
        provided without charge to CLEC. Pages in excess of two will be charged
        by PACIFIC in accordance with the nondiscriminatory rates contained in
        PACIFIC's Schedule Cal P.U.C. tariff No. 175-T, Sec.9.2 ("Customer Guide
        Service Tariff"). The form and content of such customer information
        section shall be determined by CLEC and shall be provided by CLEC to
        PACIFIC. However neither Party's content can contain puffery or rate
        comparisons with other companies. At CLEC's option, the form and content
        of this customer information may vary per community directory.

6.      SALE OF CLEC SUBSCRIBER LISTING INFORMATION

        PACIFIC will include Subscriber List Information of published CLEC local
        exchange customers in PACIFIC's Telephone Directory Reproductions Rights
        Service, unless instructed in writing by CLEC not to release Subscriber
        List Information to independent directory publications. PACIFIC will
        include the Subscriber List Information of CLEC local exchange customers
        in PACIFIC's voice and electronic
        Directory Assistance Services.

        Section 2 notwithstanding and subject to the following conditions, CLEC
        may direct PACIFIC not to release CLEC's Customers' Subscriber List
        Information to independent directory publications if the Parties first
        agree:

                1)      on the timing and method for CLEC to specify which CLEC
                        Customer Subscriber List Information is not to be
                        included in sales to independent directory publications;
                        and,

        If the Parties can not agree on the timing, method or price the Parties
        shall use the Alternative Dispute Resolution Process set forth in
        Attachment 3.

               referred to as "Local Service."

        1.2    The rights, obligations and duties set forth in this Attachment
               are subject to the Act, regulations thereunder and relevant
               Commission decisions.

2.      GENERAL TERMS AND CONDITIONS FOR RESALE

        2.1    PRICING

               The prices charged to CLEC for Local Service are set forth in
               Attachment 8 of this Agreement. All Telecommunications Services,
               including without limitation, promotions of more than 90 days
               duration, shall be available to CLEC at wholesale rates as
               specified in Attachment 8, and shall be no less favorable than
               the wholesale rates made available by PACIFIC to similarly
               situated CLCs; provided, however, pursuant to section 252 of the
               Act, implementing regulations and any court decisions applicable
               thereto, PACIFIC shall make available to CLEC, without
               unreasonable delay, any Local Service contained in any agreement
               to which PACIFIC is a party that has been filed and approved by
               the Commission. CLEC shall be subject to the same term
               commitments, volume commitments, and prohibitions against end
               user aggregation to satisfy volume discounts as apply to
               PACIFIC's retail customers and the resale discount set forth in
               Attachment 8 shall be applied to CLEC on a customer-by-customer
               basis. In no event shall CLEC be required to agree to volume or
               term commitments (other than those which may be applicable to
               PACIFIC's end user customers) as a condition for obtaining Local
               Service at wholesale rates.

        2.2    RESALE RESTRICTIONS

                      To the extent consistent with applicable rules and
               regulations of the FCC and the Commission, including, without
               limitation, Decision 96-03-020 of the Commission, CLEC may resell
               Local Services to provide Telecommunications Services. PACIFIC
               will not impose unreasonable or discriminatory conditions or

               Services that PACIFIC has grandfathered or grandfathers in the
               future may only be resold to grandfathered subscribers.

        2.3    DIALING AND SERVICE PARITY; NUMBER PORTABILITY

               2.3.1  Unless technically infeasible, for resold services,
                      PACIFIC shall ensure that all CLEC Customers experience
                      the same dialing parity as similarly-situated PACIFIC
                      customers.

               2.3.2  For resold services, PACIFIC shall ensure that all CLEC
                      Customers experience the same service levels as similarly
                      situated PACIFIC customers, and, unless technically
                      infeasible, that there is no loss of features or
                      functionalities, including, but not limited to: same dial
                      tone and ringing; same capability for either dial pulse or
                      touch tone recognition; flat and measured services; speech
                      recognition as available; same extended local free calling
                      area; 1+ IntraLATA toll calling; InterLATA toll calling
                      and international calling; 500, 700, 800, 900, 976 and

                      third number billing.

        2.4    CHANGES IN RETAIL SERVICE

               PACIFIC will notify CLEC of any changes in the terms and
               conditions under which it offers Telecommunications Services at
               retail to subscribers who are not telecommunications service
               providers or carriers, including, but not limited to, the
               introduction of any new or discontinuance of any features,
               functions, services, or promotions or the discontinuance of
               current features or services, at least sixty (60) days prior to
               the effective date of such change; provided, however, that with
               respect to terms and conditions contained in a contract between
               PACIFIC and one of its end users, PACIFIC shall notify CLEC of
               changes in such terms and conditions immediately upon signing any
               amendment to such contract.

        2.5    PRIMARY LOCAL EXCHANGE CARRIER SELECTION

               PACIFIC shall apply the principles set forth in Section 64.1100
               of the FCC Rules (47 C.F.R. Section 64.1100) to the process for
               end-user selection of a primary local exchange carrier. PACIFIC
               shall not require a written letter of authorization from the
               customer in order to process an CLEC order for Local Service for
               the customer; provided, however, that if CLEC requests a
               customer's service record, the provisions of Section 5.5.1 of
               this Attachment shall apply.

3.      REQUIREMENTS FOR SPECIFIC SERVICES

        3.1    CENTREX REQUIREMENTS

               3.1.1  At CLEC's option, CLEC may purchase the entire set of
                      CENTREX features or a subset of any one or any combination
                      of such features. The CENTREX Service provided for resale
                      will meet the following requirements:

                      3.1.1.1   All deployed features and functions of CENTREX
                                Service offered to any PACIFIC customer, whether
                                offered under tariff or otherwise, shall be
                                available to CLEC, where deployed, for resale,
                                without any customer class restrictions other
                                than those which may be imposed by applicable
                                orders of the FCC or the Commission, including,
                                without limitation, Commission Decision
                                96-03-020.

                      3.1.1.2   PACIFIC shall provide to CLEC a list of all
                                CENTREX features and functions offered by
                                PACIFIC within ten (10) days of the Effective
                                Date of this Agreement.

                      3.1.1.3   All service levels and features of CENTREX
                                Service provided by PACIFIC for resale by CLEC
                                shall be at parity to those provided to
                                PACIFIC's end user customers.

                      3.1.1.4   CLEC shall pay a one time, non-recurring charge,
                                as set forth in Attachment 8 of this Agreement
                                to pay for the cost of suppressing the need for
                                CLEC Customers to dial "9" ("Assumed Dial 9")
                                when placing calls outside the CENTREX System.
                                CLEC recognizes that there are certain problems
                                with Assumed Dial 9 on Centrex but such problems
                                would also be experienced by a PACIFIC Centrex
                                customer using Assumed Dial 9.

                      3.1.1.5   CLEC may utilize Automatic Route Selection
                                ("ARS").

        3.2    CLASS AND CUSTOM FEATURES REQUIREMENTS

               CLEC may purchase the entire set of CLASS and Custom Calling
               Features and functions where deployed by PACIFIC and made
               available to its end-user customers, or any one or any
               combination of such features, on a customer-specific basis,
               without restriction on the minimum or maximum number of lines or
               features that may be purchased. PACIFIC shall provide to CLEC a
               list of all such CLASS and Custom features and functions within
               ten (10) days of the Effective Date.

        3.3    LIFELINE SERVICE

               When a customer eligible for the Lifeline Service chooses to
               obtain Local Service from CLEC, PACIFIC shall flag the account as
               a Lifeline Service Customer and forward this information in
               electronic format in accordance with the procedures set forth
               herein. For the first ninety (90) days after the Effective Date
               of this Agreement, PACIFIC will make Lifeline Service available
               to CLEC at the wholesale discount specified in Attachment 8; for
               such period of time, CLEC will provide PACIFIC with information
               sufficient to permit PACIFIC to seek reimbursement from the
               Universal Lifeline Telecommunications Service Fund. Thereafter,
               CLEC will purchase basic local exchange service from PACIFIC,
               less the applicable wholesale discount, for resale to Lifeline
               Service customers (including customers who continue as CLEC
               Lifeline Service customers after the first ninety days) and will
               seek reimbursement from the Universal Lifeline Telecommunications
               Service Fund.

        3.4    INTERCEPT AND TRANSFER SERVICE

               Upon request from CLEC, PACIFIC will provide an intercept
               referral message that includes any new CLEC telephone number, for
               residential customers for three (3) months, and business
               customers for twelve (12) months, and PACIFIC will provide
               directory updates at the next publication. This intercept
               referral message shall be approved by CLEC and shall be similar
               in format to the intercept referral messages currently provided
               by PACIFIC for its own end users. Custom messages or extension in
               duration of the referral shall be subject to the charges set
               forth in Attachment 8.

        3.5    E9111911 SERVICES

               PACIFIC shall provide to CLEC, for CLEC Customers, E91 1/911 call
               routing to the appropriate Public Safety Answering Point
               (~'PSAP") with a parity level equal to that provided to PACIFIC's
               end-user customers. PACIFIC shall provide and validate CLEC
               Customer information to the PSAP. Upon request, PACIFIC will
               provide documentation to CLEC showing the correlation between
               PACIFIC's LSOs/rate centers to their E91 1 Selective Router
               tandems. At the price set forth in Attachment 8, PACIFIC will
               provide CLEC with access to PACIFIC's Master Street Address Guide
               (MSAG), in paper form and magnetic tape, for purposes of allowing
               CLEC to update and validate customer records in the E91 1
               Management System (E91 1 MS) database used to support E91 1/911
               services. PACIFIC will offer to CLEC a diskette version of the
               MSAG, when available; availability is expected in the first
               quarter of 1997. Nothing in this Agreement precludes CLEC from
               establishing and updating its own ALI/DMS data base

                      4.2.1.1   The calls will be unbranded, with no reference,
                                express or implied, to PACIFIC.

                                the Effective Date of this Agreement in an
                                effort to find a solution which can be
                                implemented by April 30,1997 for PACIFIC to

                                CLEC Network. In the event the Parties are
                                unable to agree within forty-five (45) days of
                                the Effective Date on a solution, the Parties
                                shall submit any dispute to Alternative Dispute

                                the Service Order process. PACIFIC will honor

                                including non-published and unlisted, as noted
                                on the Service Order Request or similar form and
                                will ensure that the listing appears as the

                                Directory Assistance Service PACIFIC provides to
                                itself and its own end users.

               technical staff to perform such testing. PACIFIC and CLEC
               technical staffs shall be available to meet as necessary to
               facilitate testing. PACIFIC and CLEC shall mutually agree on the
               schedule for such testing.

        5.9.3  At either Party's request, each Party shall provide to the other
               Party any results of the testing performed pursuant to the terms
               of this Attachment. Either Party may review such results and

            SPECIFICATIONS, SERVICE DESCRIPTIONS, AND IMPLEMENTATION
                    SCHEDULE FOR UNBUNDLED NETWORK ELEMENTS

1.      GENERAL: UNBUNDLED NETWORK ELEMENTS

        1.1.   Access To Unbundled Elements Shall Be Specified Herein and Not
               Presumed. The Network Elements offered under this Agreement shall
               be clearly specified in this Agreement or the attachments hereto.
               In no event will it be presumed that access to an Network Element
               is offered unless so specified. The methods of access to Network
               Elements described in this Attachment are not exclusive. PACIFIC
               will make available any other form of access requested by CLEC
               that is consistent with the Act and the regulations thereunder.
               Requests for Network Elements not specified in this Attachment
               shall be processed according to the process described in Section
               1.6 below.

        1.2    Consistent with the terms and conditions in this Attachment and
               the Act and regulations thereunder, PACIFIC shall offer each
               Network Element individually and in combination with any other
               Network Element or Network Elements in order to permit CLEC to
               combine such Network Element or Network Elements with another
               Network Element or other Network Elements obtained from PACIFIC
               or with network components provided by itself or by third parties
               to provide Telecommunications Services to its customers.

        1.3.   Consistent with the terms and conditions in this Attachment and
               the Act and regulations thereunder, PACIFIC will permit CLEC to
               interconnect CLEC's facilities or facilities provided by CLEC or
               by third parties with each of PACIFIC's Network Elements at any
               point designated by CLEC that is technically feasible.

        1.4.   CLEC may use one or more Network Elements to provide any
               Telecommunications Service. If CLEC requests a Combination not
               specified in this Agreement and for which the Parties have not
               agreed on methods and procedures for pre-ordering, ordering,
               provisioning, maintenance, billing and pricing, the Parties will
               meet and confer pursuant to Section 1 6, below, to establish the
               processes necessary to provide the combination. In the event the
               Parties can not agree on technical feasibility or any of the
               matters specified in the foregoing sentence, the Parties will
               follow the dispute resolution process set forth in Attachment 3
               to the Agreement.

        1.5.   For each Network Element, PACIFIC shall specify a demarcation
               point (e.g., an interconnection point at a Digital Signal Cross
               Connect or Light Guide Cross Connect panel or a Main Distribution
               Frame) and, if necessary, access to such demarcation point, which
               is mutually agreed to by the Parties. However, where PACIFIC
               provides contiguous Network Elements to CLEC, PACIFIC may
<PAGE>   67
                                                                    Attachment 6
                                                                               2

               provide the existing interconnections and no demarcation point
               shall exist between such contiguous Network Elements.

        1.6.   Attachments 6 and 7, together with Attachments 5,11,12, 13 and
               14, which collectively describe the Operating Support System
               Network Element, list the Network Elements and Combinations that
               CLEC and PACIFIC have identified as of the Effective Date of this
               Agreement. CLEC and PACIFIC agree that the Network Elements and
               Combinations identified in this Agreement are not exclusive. The
               process of requesting access to an Network Element or Combination
               not identified herein shall be as follows:

               1.6.1    Either Party may identify an Network Element or
                        Combination, that is not currently available in
                        PACIFIC's network, by providing written notice to the
                        other Party, which notice shall include a description of
                        the Network Element or Combination adequate to determine
                        technical feasibility and development requirements.

               1.6.2    The Parties agree to immediately work together to
                        determine (a) the technical feasibility of the request
                        and (b) the requirements to develop the request, and the
                        anticipated cost of developing the quote. If the Network
                        Element or Combination is identified by CLEC, PACIFIC
                        shall be allowed a commercially reasonable period of
                        time to evaluate the technical feasibility of the
                        request and the requirements to develop the requested
                        Network Element or Combination. Notwithstanding the
                        foregoing, if the Parties cannot agree within forty-five
                        (45) days (or such other period of time as may be
                        mutually agreeable), whether the Network Element or
                        Combination is technically feasible, or on the
                        requirements necessary to develop the Network Element or
                        Combination, the Parties shall use the alternate dispute
                        resolution process set forth in Attachment 3 to this
                        Agreement.

               1.6.3    The costs of developing the Network Element or
                        Combination, which includes, but is not limited to, the
                        cost of developing the quote, shall be recovered from
                        any entity which utilizes the Network Element or
                        Combination so identified, including PACIFIC and its
                        affiliates. In addition, CLEC shall pay its share of
                        PACIFIC's costs of developing any Network Element or
                        Combination, not identified in this Agreement
                        (including, but not limited to, the cost of developing
                        the quote) if CLEC requests development of the Network
                        Element or Combination but subsequently determines not
                        to purchase the Element or Combination. In all cases,
                        CLEC and PACIFIC shall meet and confer on the amount of
                        such costs, each Party's respective share of such costs,
                        and the method of recovery. In the event the Parties
                        cannot agree on the amount and method of recovery, the
                        Parties shall track their respective development costs
                        and will use the alternative dispute resolution process
                        set forth in

<PAGE>   68
                                                                    Attachment 6
                                                                               3


                        Attachment 3 to this Agreement. Any determination made
                        in alternative dispute resolution shall be subject to
                        modification by a subsequent decision of the Commission.
                        In no event shall either Party allow the pendancy of a
                        dispute concerning development costs to delay analysis
                        or implementation of the Network Element or Combination.

        1.7    Unless specified otherwise in this Attachment, PACIFIC will make
               the Network Elements identified in this Agreement, and all
               Combinations specified herein used by PACIFIC in its network,
               available on the Effective Date of this Agreement.

        1.8    The charge(s) for Network Elements requested pursuant to Section
               1.6 above shall be specified by amendment to Attachment 8.

        1.9    Implementation Costs Implementation costs for all Network
               Elements set forth in this Attachment will be determined and
               recovered as specified in Attachment 8.

2.      NETWORK INTERFACE DEVICE (NID)

        2.1    General Description and Specifications of the Network Element

               2.1.1    Description. NID is PACIFIC's terminal that is used to
                        connect the end user customer's inside wire with the
                        telephone network. In addition, the NID is the final
                        termination point, or DEMARC (demarcation point) in the
                        loop network where an end user customer connects its
                        inside wire to a telephone company's loop network.
                        Connection to PACIFIC's NID will permit CLEC to obtain
                        direct access to the end user customer's inside wire by
                        attaching its connecting facility directly to the same
                        screws or lugs being used by PACIFIC to serve the
                        customer.

               2.1.2.   Types of NID. Under this Agreement, PACIFIC shall offer
                        access to two general types of NIDs:

                      2.1.2.1. Simple NID, which is a standard network interface
                               (SNI) the use of which permits the end user's
                               customer wiring to be isolated from PACIFIC's
                               network.

                      2.1.2.2. Complex NID, which is a building terminal where
                               end user customer wiring terminates on PACIFIC's
                               network.

        2.2.   Form of Access

                        2.2.1. Form of Access Applicable to All NIDs In all
                        cases (simple and complex), access to PACIFIC's NID will
                        only be available through a separate NID provided by
                        CLEC, and a separate connecting facility running either
                        between the two NIDs, or, where a connector block is
                        available, between CLEC's NID and the connector block
                        where the end

<PAGE>   69
                                                                    Attachment 6
                                                                               4


                        user customer's inside wire is attached. Unless
                        otherwise agreed in writing, CLEC shall be responsible
                        for providing its own NID and its own connecting
                        facility. In addition, CLEC shall be responsible for
                        obtaining all approvals necessary to place its NID and
                        the connecting facility on the owner's premise. Nothing
                        in the agreement precludes the end-user customer from
                        re-terminating its inside wire to the CLEC-provided NID
                        thus eliminating the need for NID-to-NID cross-connects.
                        In addition, should CLEC purchase a combination of
                        PACIFIC's NID and PACIFIC's Links, a separate CLEC NID
                        will not be required.

               2.2.2.   Ordering. CLEC shall order access to PACIFIC's unbundled
                        NID by placing an order, requesting access to the
                        unbundled NID with PACIFIC's Local Interconnection
                        Service Center (LISC).

               2.2.3.   When orders for simple unbundled NIDs are received by
                        PACIFIC, PACIFIC shall make available to CLEC
                        information, where available, indicating the type of NID
                        currently employed (e.g., SNI, MPOE with Binding post
                        identification, MPOE with color code identification, or
                        neither); When orders for complex unbundled NIDs are
                        received by PACIFIC, PACIFIC shall make available to
                        CLEC information indicating the type of NID currently
                        employed ~ SNI, MPOE with Binding post identification,
                        MPOE with color code identification, or neither).

        2.3.   General Terms and Conditions

               2.3.1.   When CLEC purchases a combination of a PACIFIC NID and a
                        PACIFIC Link. Section 2.3.2 through 2.3.7, 2.3.10 and
                        2.4 will not be applied.

               2.3.2.   Dispatch. If the Parties agree that dispatch is required
                        (e.g., to clear or make available spare Binding posts in
                        the PACIFIC NID or to secure PACIFIC's facilities at the
                        premises), then PACIFIC will dispatch a service
                        technician to complete all necessary work at the
                        customer's premise to protect PACIFIC's facilities.
                        Dispatch charges as set forth in Attachment 8, shall
                        apply with each such order.

               2.3.3.   Protection of Facilities. In no case shall either Party
                        connect to the NID or tie down its connecting facility
                        directly over the other Party's facility without prior
                        approval of the other Party and without conditioning
                        having been performed to isolate each Party's network.
                        Furthermore, in no instance shall either Party attach
                        its connecting facility in any manner so as to cause
                        voltage or its own dial tone to occur on the other
                        Party's network.

               2.3.4.   Coordination. Unless requested by CLEC, no coordination
                        is provided. If CLEC requests coordination, charges will
                        be applied as specified in Attachment 8. In addition,
                        unless otherwise agreed by CLEC and PACIFIC, neither
                        Party shall access the other Party's NID unless the
                        owning Party's service technician is present, or unless
                        the owning Party has already made the necessary
                        modifications to isolate its network.

               2.3.5    SNI Conversion. In all residential or small business
                        locations where a protector is used to connect to the
                        end user customer's inside wire instead of a SNI, at
                        CLEC's option, either the protector will be replaced and
                        a SNI installed or CLEC will install its own SNI and
                        connect the customer's inside wire to the new SNI. If
                        CLEC requests PACIFIC to install a new SNI, PACIFIC and
                        CLEC agree that the placement of a SNI will benefit each
                        Party, and therefore the cost of installing the new SNI
                        will be shared equally by PACIFIC and CLEC. The charges
                        for new SNI installation are specified in Attachment 8.

               2.3.6.   Connector Blocks When connecting to a connector block,
                        CLEC and PACIFIC will ensure that PACIFIC's jumpers will
                        be completely disconnected and not left hanging free so
                        as to cause potential interference with other facilities
                        of CLEC, PACIFIC, or the end user customer.

               2.3.7.   Drops. Either Party shall be permitted to secure its
                        drop facility to its SNI by grounding same in an
                        appropriate manner. Upon disconnection of service to the
                        end user customer, either Party may leave its drop in
                        place until another LEC or CLC needs access to the NID
                        to provide service to the customer.

               2.3.8    Gaining Access the NID. The Parties each acknowledge and
                        agree that a special tool is necessary for access to
                        PACIFIC's side of the SNI. Neither Party shall attempt
                        to access any type of NID without the proper tool, and
                        any party accessing the SNI, protector, connector block,
                        or any other form of NID, shall exercise reasonable care
                        and sound technician practices so as to avoid damage to
                        the NID. Nothing in this section shall be construed to
                        allow either Party to connect its loops directly to the
                        other Party's NID.

               2.3.9    Tagging End User Customer Facilities. Upon request,
                        PACIFIC will dispatch a technician to tag the end user
                        customer's inside wire facilities on the customer's side
                        of the NID. In such cases, a dispatch charge shall
                        apply, as specified in Attachment 8.

               2.3.10.  Special Construction Charges. In the event any Special
                        Construction is required to implement this unbundled
                        element at any given location,

                                                                               8


               3.4.2.   CLEC will provide end-user customer listing information
                        for the purpose of providing E91 1 Service.

        3.5.   Implementation Schedule

               3.5.1    2-Wire Basic and 2-Wire Assured Link Service will be
                        available on an unbundled basis on the Effective Date
                        from all PACIFIC Wire Centers on a first-come,
                        first-served basis, applicable to all carriers,
                        including PACIFIC, and subject to the availability of
                        PACIFIC's facilities and facilities at the MPOE at the
                        premise of the CLEC end user customer. However, certain
                        of PACIFIC's geographical areas are currently served
                        solely via integrated digital loop carrier ("IDLC"). In
                        such areas PACIFIC will make reasonable efforts to
                        provide Links using copper facilities. Where copper
                        facilities are not available, PACIFIC will use other
                        methods to provide such Links and Special Construction
                        charges may apply.

               3.5.2    Combination of PACIFIC's NID and its 2-Wire Basic/2-Wire
                        Assured Link Service will be available on the Effective
                        Date.

               3.5.3    Implementation of other Link products. 2-Wire Digital
                        (ISDN/xDSL Capable) Links and 4-Wire Digital (1.544 mbps
                        Capable) Links shall be available on March 31,1997.
                        4-Wire Analog Basic Links, 4-Wire Analog Assured Links
                        and 2-Wire Copper Links will be available on March
                        31,1997; prior to this date, these facilities will be
                        installed on a case-by-case basis pursuant to the mutual
                        agreement of the Parties, provided, the provisioning
                        intervals in Attachments 11 and 17 will not apply to
                        these facilities until the Parties agree on
                        pre-ordering, ordering, provisioning and maintenance for
                        these facilities.

               3.5.4    Implementation of Links combined with LSNE (Options A, B
                        and C). Links may be combined with LSNE simultaneously
                        with the availability of the particular LSNE Option
                        pursuant to the LSNE implementation schedule specified
                        in this Attachment.

        3.6    Rates CLEC agrees to pay the rates for Loops specified in
               Attachment 8. There will be no separate charge for NID when CLEC
               purchases an unbundled loop.

4.      UNBUNDLED SWITCHING

        4.1.   Unbundled Local Switching Network Element (LSNE). PACIFIC shall
               make available unbundled switching capacity, including dial

                                                                               9


               CLEC must obtain a Line Side Port (including a telephone number
               and, at CLEC's option, a directory listing) for access to the
               switching functions and vertical features provided by the
               switch, and some designation of trunking for completion of
               calls, with the exception of intra-switch calls. All
               intra-switch calls are completed using PACIFIC's switch and no
               trunk designation is made for completion of such calls.

               4.1.1.   Types of charges

                      4.1.1.1. Line Port charges as set forth in Attachment 8.

                               for switching. The issue of the appropriate
                               charges for vertical features, if any, shall be
                               as specified in Attachment 8.

                      4.1.1.3. Any applicable directory assistance or operator
                               assistance charges as set forth in Attachment 8.

                      4.1.1.4. Usage sensitive (per minute of use) local
                               switching charges, as set forth in Attachment 8
                               and Attachment 18. Usage will be recorded in one
                               second increments. Usage seconds will be totaled
                               for the entire monthly bill and then rounded to
                               the next whole minute. Usage sensitive local
                               switching charges will be on a per minute of use
                               basis and applied to all originating and
                               terminating traffic, including, but not limited
                               to local, toll, E 911 calls, calls to time and
                               weather announcements, etc. PACIFIC will (where

                      4.2.1.1. Standard Tandem Switching Tandem Switching allows
                               use of the Tandem Switch itself for the
                               transmission of calls between two switches
                               connected to that tandem, without any customized
                               routing. PACIFIC's unbundled Tandem Switching
                               will permit access to the Tandem Switch to
                               originate a call to, or terminate a call from, a
                               CLC to a PACIFIC End Office, another LEC,
                               Wireless Service Provider, or another switch,
                               using the normal routing established in PACIFIC's
                               tandem.

                      4.2.1.2. Custom Tandem Switching. In addition to the
                               standard Tandem Switching capabilities, custom
                               Tandem Switching will allow CLEC to originate a
                               call through PACIFIC's tandem to a CLC, another
                               LEC, Wireless Service Provider, or another switch
                               using CLEC's own interoffice facilities. Custom
                               Tandem Switching consists of three options:

                             4.2.1.2.1 Option 1: Custom Basic--Use of PACIFIC's
                                       Shared Transport. This option uses
                                       screening that treats CLEC as a homing
                                       End Office. The Custom Basic unbundled
                                       Tandem Switching may use dedicated tandem
                                       trunk groups that allow full LATA-wide
                                       completion over PACIFIC's shared
                                       transport. [EMR records will need to be
                                       exchanged with ILECs who receive calls
                                       initiated from a CLC completing over
                                       PACIFIC's network.] Calls routed to CLEC
                                       will use normal LERG routing.

                             4.2.1.2.2 Option 2: Custom Simple--Use of PACIFIC's
                                       Common Transport This option uses
                                       screening that treats CLEC as an IEC. The
                                       Custom Simple unbundled Tandem Switching
                                       will use dedicated trunk groups towards
                                       PACIFIC's common transport that will
                                       limit calls to the single tandem serving
                                       area. This option is only able to use
                                       common transport in the terminating
                                       direction. Originating calls from
                                       PACIFIC's End Offices must use shared
                                       transport to the tandem. Custom Simple
                                       uses a Type 2A trunk port with unique
                                       screening capabilities to route traffic
                                       to common transport trunk groups.

                             4.2.1.2.3 Option 3: Custom Complex--Routing
                                       Designed to CLEC's Specifications. The
                                       Custom Complex tandem unbundled switching
                                       will use customized routing for calls

                                                                              14


                                       sent from CLEC to PACIFIC's tandem that
                                       will be designed to CLEC's
                                       specifications, where technically
                                       feasible. The use of route advance or
                                       overflows with this option will not
                                       advance to or from dedicated trunk ports
                                       to PACIFIC common or shared transport.
                                       PACIFIC cannot bill the overflow.
                                       Notwithstanding the foregoing, the
                                       Parties will meet and confer immediately
                                       after the Effective Date of this
                                       Agreement in an effort to find a solution
                                       which can be implemented to enable
                                       PACIFIC to bill the overflow. In the
                                       event the Parties are unable to agree
                                       within forty-five (45) days of the
                                       Effective Date on a solution, the Parties
                                       shall submit any dispute to Alternative
                                       Dispute Resolution as set forth in
                                       Attachment 3.

                      4.2.1.3  When CLEC uses PACIFIC's LSNE (except where CLEC
                               requests Dedicated Transport using Options B or
                               C), use of the tandem is included in the common
                               transport charges set forth in Attachment 8.

               interconnection to its SS7 signaling network to enable signaling
               necessary for call routing and completion. PACIFIC will also make
               available unbundled nondiscriminatory access to SS7 signaling
               links and PACIFIC's Signaling Transfer Points (STPs).

        6.2.   Form of Access and General Terms and Conditions

               6.2.1.   The Parties will interconnect their networks using SS7
                        signaling protocol as defined in Bellcore Technical
                        Reference GR-246, and GR-31 7 and GR-394 for ISDN User
                        Part (ISUP) for trunk signaling.

               6.2.2.   CLEC may establish CCS interconnections with PACIFIC
                        either directly or through a third party. CCS
                        interconnection, whether direct or by third party, shall
                        be pursuant to the PACIFIC Bell/Nevada Bell CCS network

                        information between the Parties to provision unbundled
                        signaling links and STP access. The Parties shall
                        mutually exchange all S57 signaling parameters,
                        including Calling Party Number (CPN), and procedures
                        that are implemented within their SS7 networks as
                        identified in the CCS/557 Interconnect questionnaire
                        provided by PACIFIC's CLEC account team or other
                        mutually agreed process. All privacy indicators of the
                        Parties will be honored. Also, CLEC will provide their
                        SS7 network node, address information and identify the
                        SS7 services they request using the SS7 questionnaire.

               6.2.4    PACIFIC will make available to CLEC PACIFIC's signaling
                        links and access to PACIFIC's STPs or access to
                        PACIFIC's STPs with CLEC-provided signaling links to
                        provide capability to support call set-up and to support
                        CCS-based features being provided on the effective date
                        of this Agreement. Signaling links will be provisioned
                        at 56 Kbps, or at 1.5 Mbps if available.

               6.2.5.   PACIFIC will provide CLEC with access through PACIFIC's
                        STPs to the following elements connected to PACIFIC's
                        SS7 network: (1) PACIFIC's SS7-capable End Offices and
                        Access Tandem Switches; (2) third-party CLC switches;
                        (3) third-party CLC STPs, if the third-party CLC and
                        PACIFIC have STP-to-STP interconnection; and (4) PACIFIC
                        will provide CLC signaling links and/or access to
                        PACIFIC's STPs for signaling between CLC's switches or
                        between CLEC and third-party switches (including
                        unbundled switching elements) when CLEC's and/or
                        third-party's switches are interconnected to PACIFIC's
                        SS7 signaling network.

               6.2.6.   At CLEC's option, CLEC may connect its switches to
                        PACIFIC's STPs by means of "A" link access and may
                        connect CLEC STPs to PACIFIC's STPs by means of "D" link
                        access. PACIFIC will designate the STP pair for
                        interconnection, and CLEC will then designate the
                        Signaling Point of Interconnection ("SPOI") within the
                        STP pair.

               6.2.7.   All "A" links provided by PACIFIC or CLEC will consist
                        of two link sets, and "D" links will consist of four
                        link sets.

               6.2.8.   CLEC's SS7 links will be interconnected to PACIFIC's
                        STPs in the same manner that PACIFIC connects its links
                        to its own STPs. When CLEC connects its links to
                        PACIFIC's STP a Port charge will apply as specified in
                        Attachment 8; provided, when CLEC provides its own links
                        it must access PACIFIC's STP Port through a collocation
                        cage.

               6.2.9.   PACIFIC will provide to CLEC all the signaling link
                        functions, and all the Signaling Connection Control
                        Point ("SCCP") functions that are deployed in PACIFIC's
                        SS7 network.

                        access. Access to LIDB/AS will allow CLEC to create,
                        modify, update or delete the end user line information
                        in PACIFIC's LIDB database for CLEC Customers when
                        PACIFIC is the carrier of record in the LERG. For an
                        CLEC end user, line information includes telephone
                        number and preassigned calling card PIN and billed
                        number screening data (collect and third number billing
                        indicators). PACIFIC's LIDB updates are processed
                        continuously through service order input to LIDB/AS,
                        which then updates LIDB.

                               itself.

                      7.1.3.2. PACIFIC shall use the end user line information
                               of an CLEC subscriber only to update and maintain
                               LIDB and not for any other purpose.

                      7.1.3.3. CLEC may create, update, modify, or delete end
                               user line information of its own subscribers
                               through the issuance of service order activity.
                               CLEC shall not create, update, modify, or delete

                               trunk groups for each NPA served.

                      8.2.5.3. CLEC must also have a point of presence ("POP")
                               at PACIFIC's DMS 200 switch within each LATA
                               served by CLEC.

                      8.2.5.4. In LATAs 722, 724, and 730, CLEC may select any
                               of PACIFIC's DMS 200 TOPS switches as its POP.

               8.2.6.   Billing records will be recorded at the TOPS switch and
                        billing detail will be passed to CABS. Detailed billing
                        records will be passed to CLEC for end user billing.

                      8.2.6.1  AMA billing will be created at the selected DMS
                               200 TOPS switch. These records will be created in
                               Expanded Bellcore AMA Format ("EBAF") Phase 2.

                      8.2.6.2  Billing will be based on operator work seconds as
                               specified in Attachment 8.

               8.2.7    For customer rate quote requests, PACIFIC's operators
                        will provide rating information if CLEC concurs with
                        PACIFIC's rates; if CLEC does not concur in PACIFIC's
                        rates, rate quote requests will be handled per Section
                        4.3.1.3 of Attachment 5.

        8.3.   General Terms and Conditions

               8.3.1.   If CLEC purchases the Operator Services unbundled
                        element, PACIFIC will provide CLEC nondiscriminatory
                        access to PACIFIC's Operator Services. The service
                        level, including any dialing delays, of the Unbundled
                        Operator Service provided to CLEC shall be at parity
                        with the Operator Service provided by PACIFIC to its own
                        customers.

               8.3.2.   BLV and BLVI. PACIFIC will offer operator-to-operator
                        BLV and BLVI to CLEC on a nondiscriminatory basis, in
                        accordance with LERG instructions. CLEC OS requires that
                        a reciprocal BLV/BLVI network be established between
                        PACIFIC and CLEC.

               8.3.3    Operator-Assisted Calls to DA ("OADA"). PACIFIC will
                        offer OADA to CLEC on a nondiscriminatory basis. OADA
                        refers to the situation in which a customer dials "0"
                        and asks the operator for DA; in such situations, the
                        customer is automatically transferred to a DA operator.

                                                                              27


                        providing OADA to CLEC, PACIFIC will connect CLEC's end
                        user customer to PACIFIC's DA operators, and PACIFIC
                        will charge CLEC as specified in Attachment 8.

               8.3.4.   PACIFIC shall not be obligated, under any circumstances,
                        to provide call handling methods or credit card or other
                        alternate billing arrangements that are different from
                        those PACIFIC provides to itself or its affiliates.

               8.3.5.   PACIFIC shall have no duty, apart from factors within
                        PACIFIC's control, to ensure that CLEC's customers can
                        in fact access PACIFIC's Operator Services.

        8.4.   Implementation Schedule

               8.4.1.   PACIFIC will make available unbundled Operator Services
                        no later than April 30, 1997.

        8.5.   Rates CLEC will pay the rates for Operator Services as specified
               in Attachment 8.

9.      DIRECTORY ASSISTANCE SERVICES

        9.1.   General Description and Specifications of the Unbundled Element

               9.1.1.   PACIFIC's unbundled Directory Assistance Service
                        provides unbundled Directory Assistance ("DA") services
                        to CLEC by utilizing PACIFIC's DA database. This service
                        includes PACIFIC's listed customers and listings
                        supplied to PACIFIC for DA use by other carriers. This
                        DA service shall be provided at parity with PACIFIC DA
                        service and will utilize the same Directory Listing
                        source of information as PACIFIC uses for its own DA
                        service. PACIFIC's unbundled DA has the following
                        service attributes:

                                 and name, or a report that the number is not
                                 available;

                        9.1.1.3  Up to three search requests per call;

                                 Canada:

                        9.1.1.5. Exchange locality information for California;

                        9.1.1.6. Use of Automated Response Unit for number
                                 quotation;

                                                                    Attachment 6
                                                                              28


                        9.1.1.7  Express Call Completion at parity with what
                                 PACIFIC provides for itself or its affiliates.

                        9.1.1.8. PACIFIC's DA is available on a statewide basis
                                 (throughout California) or by individual NPA.

                        9.1.1.9. PACIFIC's DA provides telephone numbers and
                                 address information within the State of
                                 California only.

               9.1.2. Nondiscriminatory Access to Directory Listings PACIFIC
                      will provide CLEC with nondiscriminatory access to
                      PACIFIC's directory listings for DA applications. CLEC
                      shall pay PACIFIC for the cost of the transfer media
                      (magnetic tape), plus PACIFIC's reasonable costs for
                      preparation and shipping of the magnetic tape. PACIFIC
                      will not permit CLEC to have access to PACIFIC's unlisted
                      customer names or unlisted customer telephone numbers.

        9.2.   Form of Access

               9.2.1. Access to Unbundled DA Services. PACIFIC will provide CLEC
                      nondiscriminatory access to PACIFIC's DA Services. The
                      service level, including any answer delays, of the
                      Unbundled DA Service provided to CLEC shall be at parity
                      with the DA Service provided by PACIFIC to its own
                      customers.

               9.2.2. Trunking Access to PACIFIC DA may be provided either
                      through PACIFIC's access tandem or by dedicated trunking
                      from End Office and routed to the appropriate DA center
                      Where CLEC uses trunking from an CLEC End Office to
                      PACIFIC's access tandem, using local interconnection
                      trunks at PACIFIC's tandem, CLEC must convert all "411"
                      dialed calls to NPA 555-1212 prior to delivery to the
                      tandem as shown in the LERG.

               9.2.3. Transport If CLEC has purchased PACIFIC's unbundled DA
                      Services element, directory transport may, at the option
                      of CLEC, be provided from where the home NPA access tandem
                      is, or from an access tandem mutually negotiated with
                      CLEC. PACIFIC will not provide transport across LATA
                      boundaries.

        9.3.   General Terms and Conditions

               9.3.1. Branding Whenever PACIFIC provides DA services on behalf
                      of CLEC, at CLEC's option, PACIFIC will brand the call as
                      an CLEC call, where technically feasible. Where not
                      technically feasible, such calls will be unbranded.

                                                                              29


               9.3.2. Unlisted Information If CLEC has purchased PACIFIC's
                      unbundled DA Services element, PACIFIC emergency operators
                      will provide emergency assistance regarding unlisted
                      customers on an equal basis as PACIFIC does to its
                      customers

               9.3.3. CLEC shall not have access to PACIFIC's customers'
                      unlisted telephone numbers.

               9.3.4. Confidentiality of CLEC's DA and Non-Published Listings
                      PACIFIC will accord CLEC's DA and Non-Published listing
                      information the same level of confidentiality that PACIFIC
                      accords its own DA and Non-Published listing information.

               9.3.5. DA Call Completion Service In conjunction with the
                      provision of unbundled DA service to CLEC, PACIFIC will
                      provide DA Call Completion Service (which is comparable in
                      every way to the DA Call Completion Service PACIFIC makes
                      available to its own end users) in those areas where DA
                      Call Completion Service is generally available and where
                      facilities permit.

               9.3.6  If CLEC purchases PACIFIC's unbundled DA Services element,
                      PACIFIC's contact with CLEC's end user customers shall be
                      limited to that effort required to process CLEC's end user
                      customers' requests for DA services. PACIFIC will not
                      transfer, forward, or redial an CLEC's end user customer's
                      call to any other location for any purpose other than the
                      provision of DA to the customer.

               9.3.7. CLEC DA service quality will be equal to that which
                      PACIFIC provides to its own DA customers.

               9.3.8. Billing

                      9.3.8.1    Billing will be handled by CABS.

                      9.3.8.2    PACIFIC will bulk-bill CLEC, with no detailed
                                 records. CLEC shall be responsible for billing
                                 its end users for this service. All bills for
                                 CLEC DA will reflect a per-call charge and the
                                 applicable transport charges.

                      9.3.8.3    PACIFIC will not credit CLEC for customer
                                 requests that are not found in the DA database.

                      9.3.8.4    All DA calls will be billable to CLEC, except
                                 as specifically mentioned herein.

        10.3   Rates CLEC agrees to pay OSS rates as specified in Attachment 8.

11.     STANDARDS FOR NETWORK ELEMENTS

        11.1   If one or more of the requirements set forth in this Agreement
               are in conflict, CLEC shall elect which requirement shall apply.

        11.2   Each Network Element and the interconnections between Network
               Elements provided by PACIFIC to CLEC shall be at least equal in
               the quality of design, performance, features, functions and other
               characteristics, including but not limited to levels and types of
               redundant equipment and facilities for power, diversity and
               security, that PACIFIC provides in PACIFIC network to itself,
               PACIFIC's own customers, to a PACIFIC affiliate or to any other
               entity.

        11.3   In the event that CLEC reasonably believes that the requirements
               of this Attachment 6 are not being met, the Parties will meet and
               confer concerning such engineering, design, performance and other
               network data, which may be necessary to cure any engineering,
               design performance of implementation deficiency. In the event
               that such data indicates that the requirements of this Attachment
               6 are not being met, PACIFIC shall cure any such deficiency as
               soon as possible.

        11.4.  Subject to this Agreement and its Attachments, PACIFIC agrees to
               work cooperatively with CLEC to provide Network Elements that
               will meet CLEC's needs in providing services to its customers.

               11.5. If PACIFIC makes available to itself or any of its end user
               customers an expedited or priority provisioning capability for
               Network Elements and interconnections

<PAGE>   96

Note 5: OS must use MOSS signaling prior to ILP (2-PIC) deployment. With ILP, OS
        can then go to FG-D (MF or SS7) if the subscriber's line is
        pre-subscribed to CLEC for intra-LATA traffic. DA requires MOSS if it
        goes to OS trunking, but FG-D cannot support 411 (3-digit).

Note 6: STP port access must be ordered on a separate order.

1.       LOCAL SERVICES RESALE

         The prices charged to CLEC for resold Local Service shall be calculated
         using the avoided cost discount set forth herein. The interim wholesale
         discount shall be [**] off the applicable retail rate for all PACIFIC
         services subject to resale. The interim discount shall remain in effect
         until the Commission determines a different wholesale discount in any
         proceeding subsequent to the Effective Date of this Agreement. Once so
         determined by the Commission, said different wholesale discount shall
         apply instead of the interim discount for the remaining Term of this
         Agreement.

         The prices shall be based on PACIFIC's retail rates applicable on the
         Effective Date, less the applicable discount. If PACIFIC changes its
         retail rates after CLEC executes this Agreement, the applicable
         discount shall be applied to the changed retail rates from the time
         such changes become effective.

         1.1.     Non-recurring Charges for Total Services Resale

                  1.1.1    Non-recurring charge(s) shall be based on PACIFIC's
                           retail rates less the applicable discount.

                  1.1.2    Notwithstanding Section 1.1.1, unless changed by the
                           Commission, PACIFIC shall NOT charge any
                           non-recurring charges to switch a customer from
                           PACIFIC's retail service to CLEC resold service.
                           PACIFIC may track its one-time, non-recurring service
                           order costs and seek recovery of these costs in an
                           appropriate Commission proceeding, which CLEC shall
                           have the right to contest. In addition, the Parties
                           disagree whether the "no change-over charge" for
                           resold services specified in this section should
                           apply in the following circumstances: (1) when CLEC
                           moves an existing Link customer (be it an existing
                           CLEC Link customer or that of another CLC) to resold
                           Local Service; (2) when CLEC moves an existing resold
                           customer of another CLC to CLEC's service. For the
                           customer movement identified in the previous
                           sentence, PACIFIC may track its non-recurring
                           provisioning costs and its one-time non-recurring
                           service order costs and seek recovery of these costs
                           in an appropriate Commission proceeding, which CLEC
                           shall have the right to contest

2.       UNBUNDLED NETWORK ELEMENTS

         The prices charged to CLEC for Network Elements are as specified in
         Appendix A to this Attachment. The prices listed in the Appendix are
         interim prices only and are subject to change to conform with the rate
         for unbundled Network Elements and non-recurring charges adopted by the
         Commission subsequent to the Effective Date of this Agreement.

                                                                    ATTACHMENT 8
                                                                          Page 3



         Once the Commission-determined prices are adopted, said prices will be
         substituted for the interim prices and shall apply for the remainder of
         the Term of this Agreement.

3.       COLLOCATION

         On an interim basis, the rates contained in PACIFIC's Schedule Cal.
         P.U.C. Tariff No. 175-T, Section 16, and FCC Tariff No. 128, Section
         16, shall apply. Any collocation rates determined by the Commission
         subsequent to the Effective Date of this Agreement shall replace such
         interim rates.

4.       INTERCONNECTION SERVICES

         PACIFIC will make interconnection arrangements available at all
         collocated locations. CLEC may choose to deliver both local and
         intraLATA toll traffic over the same trunk group(s). With respect to
         the previous sentence, CLEC will provide PACIFIC with the Percent Local
         Usage (PLU) factor to facilitate billing of the local interconnection
         rate. CLEC's PLU determination shall be subject to reasonable audit by
         PACIFIC pursuant to Section 11 of this Agreement.

         Prices and terms for interconnection services are specified in
         Attachment 18 and Appendix 1 to this Attachment 8, including, without
         limitation, the calculation of applicable charges for the completion of
         toll and local traffic when PACIFIC's LSNE is used, the manner for
         determining when reciprocal compensation applies for the exchange of
         local traffic, and the reciprocal compensation rates for local and toll
         traffic.

5.       RIGHTS OF WAY, CONDUITS AND POLE ATTACHMENTS

         CLEC shall pay PACIFIC a fee consistent with 47 U.S.C. Section 224 and
         FCC and Commission regulations thereunder for placement of CLEC's
         facilities in or on PACIFIC's poles, conduits, or rights of way. The
         Parties shall mutually agree on such fee and in the event of any
         dispute, will use the Alternative Dispute Resolution process set forth
         in Attachment 3. Such fee is subject to change, pursuant to Section 9.3
         of this Agreement, in the event the FCC issues new rules or the
         Commission adopts rules setting forth a new methodology.

6.       OTHER

         The following prices also shall apply:

         -        E911 (when CLEC orders this service as a facilities-based
                  carrier): PACIFIC's tariff rates shall apply as set forth in
                  Exhibit 1 to this Attachment 8.

         -        PACIFIC shall provide RCF to CLEC pursuant to the terms of the
                  DNCF tariff (including any modification subsequently adopted
                  by the Commission) filed by PACIFIC, except that the Parties
                  (a) shall establish accounts to track



                                       3

<PAGE>   103

                                                                    ATTACHMENT 8
                                                                          Page 4



                  their own costs of providing INP pursuant to this Agreement
                  and (b) agree to recover such costs consistent with FCC and
                  Commission requirements at such time as such requirements are
                  established. Until any FCC or Commission order establishes a
                  different cost recovery mechanism, a "bill and keep"
                  arrangement will apply to the ported segment of any ported
                  call between the Porting Party's switch and the Ported-to
                  Party's switch.

         -        References to PACIFIC's Switched and Special Access tariffs or
                  service shall mean the rates in PACIFIC's intrastate (Cal.
                  Schedule PUC 175-T) or interstate (FCC No. 128) access
                  tariffs, as applicable, shall apply.

         -        Warm line transfer: Where the Parties have agreed that CLEC
                  will pay PACIFIC for warm line transfer, PACIFIC's tariffed
                  rate for this service shall apply.

         -        Centrex Assumed Dial 9: PACIFIC's tariffed rate for this
                  service shall apply.

         These rates shall remain in effect until the Commission determines
         different rates in any proceeding subsequent to the Effective Date of
         this Agreement. Once so determined by the Commission, said different
         rates shall apply instead of the rates set forth herein for the
         remaining Term of this Agreement.

7.       IMPLEMENTATION COST RECOVERY

         The Parties disagree whether or in what amount PACIFIC should charge
         CLEC for implementation costs and service quality in excess of parity
         incurred as a result of requests to establish and provide
         interconnection services, Local Services, Network Elements or
         Combinations. PACIFIC shall track all such costs and propose recovery
         of same to the Commission. To the extent granted by the Commission,
         CLEC shall pay such costs as ordered by the Commission. CLEC is free to
         contest PACIFIC's right to recover any such costs and/or what its share
         of such costs should be.

8.       TO BE DETERMINED

         In this Agreement, rates for certain services, Network Elements and
         Combinations are specified as "To Be Determined" (TBD). In addition,
         numerous provisions of this Agreement refer to prices set forth in
         Attachment 8. In the event of such a reference in this Agreement where
         there is no corresponding price in this Attachment 8, it shall be
         deemed to be TBD. With respect to all TBD prices, prior to CLEC
         ordering any such TBD items, the Parties shall meet and confer to
         establish a price. If no agreement is reached, the Parties shall refer
         any disputes to the Alternative Dispute Resolution process set forth in
         Attachment 3. Any rates set in arbitration shall be subject to
         modification by any subsequent decision of the Commission. CLEC shall
         be responsible for payments of any such rates so established as ordered
         in arbitration or by the Commission.

                                  ATTACHMENT 9
              ACCESS TO VERIGATE AND LEX OPERATIONS SUPPORT SYSTEMS


1.       GENERAL CONDITIONS

         1.1      This Attachment sets forth the terms and conditions under
which PACIFIC provides access to three of PACIFIC'S operations support systems
(OSS) "functions" to CLEC for pre-ordering, ordering and order statusing,
VeriGate and LEX respectively.

         1.2      CLEC agrees to utilize VeriGate and LEX as described herein,
only for the purposes of establishing and maintaining Resale services or UNEs
through PACIFIC. CLEC agrees that the ordering interface will only support those
Resale and UNE services for which industry standard ordering conventions have
been adopted by the OBF. and implemented by PACIFIC. In addition, CLEC agrees
that such use will comply with the summary of SBC's Operating Practice 113, as
attached to this Attachment and the User ID request form. The Alternative
Dispute Resolution (ADR) process set forth in Attachment 3 shall apply to any
issues which arise under this Attachment 9, including any alleged non-compliance
with these security guidelines.

         1.3      CLEC's access to pre-order functions described in 2.2.2 and
2.3.2 will be governed by Sections 5.5 of Attachment 5 to this Agreement for
Resale services. and by Section 5.2 of Attachment 11 to this Agreement for UNE
services.

         1.4      By utilizing the electronic interfaces described herein to
access OSS functions, where CLEC has direct ordering capability, CLEC agrees not
to knowingly alter any applicable Resale rates and charges where they are
subject to the terms of this Agreement and applicable PACIFIC tariffs or PACIFIC
UNE rates and charges per the terms of this Agreement. CLEC agrees to use
reasonable business efforts to submit orders that are correct and complete.
Pacific will use reasonable business efforts to reject for processing CLEC
orders which are not correct and complete. The Parties agree to conduct internal
and independent reviews for accuracy. The audit rights in Section 11 of the
Agreement shall apply.

         1.5      The Information Services (I.S.) Call Center provides a
technical support function for the OSS interfaces described in this Attachment.
CLEC will also provide a single point of contact for technical issues related to
the electronic interfaces.

         1.6      PACIFIC and CLEC will establish interface contingency plans
and disaster recovery plans for the OSS interfaces described in this Attachment.

         1.7      The Parties agree that the Change Management Process agreed to
and documented under the auspices of the CPUC OSS 011 will be used to manage
changes to LEX and Verigate.

2.       PRE-ORDER

         2.1      Where available to Pacific, PACIFIC will provide real time
access to pre-order functions to support CLEC ordering of Resale services and
UNE via the electronic interfaces described herein. The Parties acknowledge that
ordering requirements necessitate the use of current, real time pre-order

                           functions for Resale Services and UNE. VeriGate may
                           be used in connection with electronic or manual
                           ordering.

3.       ORDERING/PROVISIONING

         3.1      PACIFIC will provide access to ordering and statusing
functions to support CLEC provisioning of Resale services and UNEs via the OSS
interfaces described below. To order Resale services and UNEs, CLEC will format
the service request to identify what features services, or elements it wishes
PACIFIC to provision in accordance with PACIFIC LSOR and other ordering
requirements which have been reviewed and discussed by both parties. PACIFIC
will provide CLEC access to the following interfaces:

                  3.1.1    LSR Exchange (LEX) is a graphical user interface
                           provided by PACIFIC that provides access to the

5.       OPERATIONAL READINESS TEST (ORT) FOR ORDERING/PROVISIONING

         5.1      Prior to initial live access to interface functionality, the
Parties shall conduct Operational Readiness Testing (ORT)-which will allow for
the testing of the systems, interfaces. and processes for the OSS functions.

         5.2      Prior to live system usage, CLEC must complete user education
classes for PACIFIC-provided interfaces that affect the PACIFIC network. Classes
are train-the-trainer format to enable CLEC to devise its own course work for
its own employees. Charges will apply for each class. Classes will be available
for and required for LEX. Optional classes will be available for VeriGate.
Schedules will be made available upon request and are subject to change. The
length of classes varies; the following table presents the applicable rates.
Ongoing class schedules may be requested from CLEC's account manager.


                                      [**]


         5.3      A separate agreement will be required as a commitment to pay
for a specific number of CLEC students in each class. CLEC agrees that charges
will be billed by PACIFIC and CLEC payment is due 30 days later. CLEC agrees
that personnel from other competitive Local Service Providers may be scheduled
into any class to fill any seats for which CLEC has not contracted. Class
availability is first-come, first served with priority given to CLECs who have
not yet attended the specific class.

         5.4      Class dates will based upon CLEC requests and PACIFIC
availability.

         5.5      CLEC agrees to pay a cancellation fee of the full price noted
in the separate agreement if CLEC cancels scheduled classes less than two weeks
prior to the scheduled start date. Should PACIFIC cancel a class for which CLEC
is registered less than two weeks prior to the schedule start date of that
class, Pacific will waive the charges for the reschedule class for the
registered students. CLEC agrees to provide to PACIFIC completed registration
forms for each student no later than one week prior to the scheduled training
class.

         5.6      CLEC agrees that CLEC personnel attending classes are to
utilize only training databases and training presented to them in class.
Attempts to access any other PACIFIC or SBC system are strictly prohibited.

                               ANCILLARY FUNCTIONS

1.            INTRODUCTION

              This Attachment 10 sets forth the Ancillary Functions that PACIFIC
              agrees to offer to CLEC so that CLEC may obtain and use unbundled
              Network Elements or PACIFIC services to provide services to its
              customers.

2.            PACIFIC PROVISION OF ANCILLARY FUNCTIONS

2.1           The Ancillary Functions that CLEC and PACIFIC have identified as
              of the Effective Date of this Agreement are Collocation, which is
              addressed in Section 3, and Right of Way, which is addressed in
              Section 4 of this Attachment. CLEC may use Collocation and Right
              of Way to provide any feature, function, or service option that
              such Ancillary Function is capable of providing or any feature,
              function, or service option that is described in the relevant
              technical references, or as may otherwise be designated by CLEC
              consistent with the Act, the regulations thereunder and relevant
              Commission decisions.

2.2           CLEC and PACIFIC agree that the Ancillary Functions identified in
              this Attachment 10 are not exclusive. Either Party may identify
              additional or revised Ancillary Functions as necessary to improve
              services to customers, to improve network or service efficiencies
              or to accommodate changing technologies, customer demand, or
              regulatory requirements. Upon the identification of a new or
              revised Ancillary Function, the Parties shall cooperate in an
              effort to negotiate mutually agreeable rates, terms and conditions
              for the provision of that Ancillary Function. If the Parties are
              unable to agree on the terms and conditions for a new or revised
              Ancillary Function that PACIFIC is required to offer under the
              terms of the Act, either Party may invoke the Alternative Dispute
              Resolution procedures established by Attachment 3. Security
              procedures agreed to by PACIFIC and CLEC for the protection of
              both Parties' service and property, including collocation spaces,
              and procedures for law enforcement interface are described in
              Attachment 16.

3.            COLLOCATION

3.1           DEFINITIONS:

3.1.1         Collocation is the right of CLEC to place equipment in PACIFIC's
              Local Serving Office (LSO) or other PACIFIC locations to
              interconnect with PACIFIC's network. Collocation also includes
              PACIFIC providing resources necessary for the operation and
              economical use of collocated equipment.

                                                                   Attachment 10
                                                                          Page 2



3.1.2         Physical collocation is defined in 47 C.F.R. Sec. 51.5.

3.1.3         Virtual collocation is defined in 47 C.F.R. Sec. 51.5.

3.2           TECHNICAL REQUIREMENTS

3.2.1         PACIFIC will provide for Physical Collocation and Virtual
              Collocation of CLEC's transport facilities and termination
              equipment necessary for interconnection of CLEC's network
              facilities to PACIFIC's network or access to unbundled network
              elements. Such collocation shall be provided at the rates
              specified in Attachment 8 and on a nondiscriminatory basis in
              accordance with the requirements of the Act and the FCC's rules
              thereunder.

3.2.2         PACIFIC shall permit collocation of any type of equipment used or
              useful for interconnection or access to unbundled network
              elements, in accordance with the Act and sections 579 through 582
              of the FCC's First Interconnection Order. Such equipment includes
              but is not limited to transmission equipment, such as optical
              terminating equipment and multiplexers, equipment for the
              termination of basic transmission facilities and such additional
              types of equipment that may be agreed to by the Parties or
              designated in future FCC or Commission rulings. If a request by
              CLEC to collocate is denied on the basis of the equipment to be
              installed by CLEC, PACIFIC shall prove to the Commission that such
              equipment is not "necessary" as defined by the FCC for
              interconnection or access to unbundled network elements.

3.2.3         When providing Virtual Collocation, PACIFIC will, at a minimum,
              install, maintain, and repair collocated equipment for CLEC within
              the same time periods and with failure rates that are no greater
              than those that apply to the performance of similar functions for
              comparable equipment of PACIFIC, provided, if CLEC utilizes
              nonstandard equipment or equipment not used by PACIFIC at the same
              location, CLEC shall pay for (a) any special equipment PACIFIC
              must purchase and (b) any training of PACIFIC personnel required
              for PACIFIC to install or maintain such non-standard or special
              equipment.

3.2.4         PACIFIC will make space available within or on its premises to
              CLEC and other requesting telecommunications carriers on a
              first-come, first-served basis, provided, however, that PACIFIC
              will not be required to lease or construct additional space to
              provide for Physical Collocation when existing space has been
              exhausted. To the extent possible, PACIFIC will make contiguous
              space available to CLEC if CLEC seeks to expand an existing
              collocation space. When planning renovations of existing
              facilities or constructing or leasing new facilities, PACIFIC
              shall take into account projected demand for collocation space.
              PACIFIC may retain a limited amount of floor space for PACIFIC's
              own specific future uses for a time period up to one year on terms
              no more favorable to PACIFIC than those that apply to other
              telecommunications carriers seeking to

<PAGE>   116

                                                                   Attachment 10
                                                                          Page 3



              reserve collocation space for their own future use. PACIFIC shall
              relinquish any space held for future use before denying a request
              for Virtual Collocation on grounds of space limitations, unless
              PACIFIC proves to the Commission that Virtual Collocation at that
              point is not technically feasible. PACIFIC may impose reasonable
              restrictions on its provision of additional unused collocation
              space ("warehousing") as described in Section 586 of the First
              Interconnection Order to collocating telecommunications carriers,
              provided, however, that PACIFIC shall not set a maximum space
              limitation on CLEC unless PACIFIC proves to the Commission that
              space constraints make such restrictions necessary.

3.2.5         PACIFIC will permit CLEC to collocate equipment and use such
              equipment to access unbundled Network Elements obtained from
              PACIFIC and will not require CLEC to bring its own transmission
              facilities to PACIFIC's premises in which CLEC seeks to collocate
              equipment for purposes of access to unbundled Network Elements.

3.2.6         PACIFIC will permit CLEC to interconnect its network with that of
              another collocating telecommunications carrier at PACIFIC's
              premises and to connect its collocated equipment to the collocated
              equipment of another telecommunications carrier within the same
              premises provided that the collocated equipment is also used for
              interconnection with PACIFIC or for access to PACIFIC's unbundled
              Network Elements. PACIFIC will provide the connection between the
              equipment in the collocated spaces of two or more
              telecommunications carriers via EISCCs and any necessary DCS or
              other equipment at the requesting competitive local carrier's
              expense, unless PACIFIC permits one or more of the collocating
              parties to provide this connection for themselves. PACIFIC need
              not permit collocating telecommunications carriers to place their
              own connecting transmission facilities within PACIFIC's premises
              outside of the actual Physical Collocation space.

3.2.7         Transferring CLEC interconnection from PACIFIC's current access
              service transport or entrance facilities to EISCCs will be
              accomplished within a mutually agreed-upon time frame; however, to
              ensure a smooth transition from such access services to EISCCs,
              CLEC must provide forecasts of its future needs for EISCC capacity
              by location at least 90 days in advance of its desired transition
              date.

3.2.8         PACIFIC will permit CLEC to subcontract the construction of
              Physical Collocation arrangements with contractors approved by
              PACIFIC, provided that PACIFIC will not unreasonably withhold
              approval of contractors. Approval by PACIFIC will be based on the
              same criteria PACIFIC uses in approving contractors for its own
              purposes.

3.2.9         PACIFIC shall provide an EISCC for intraoffice cross-connect

                                                                          Page 9



              Commission and this Attachment 10, Section 3, or through tariffs,
              in the event PACIFIC files tariffs covering such facilities.

4.2.2         PACIFIC shall provide CLEC with non-discriminatory and
              competitively neutral access, on a first-come, first-served basis,
              to ROW, conduit, ducts, pole attachments and entrance facilities
              that PACIFIC owns or controls.

4.2.3         Upon request, PACIFIC shall provide CLEC reasonable access on a
              non-discriminatory and competitively neutral basis to building

              personnel must be escorted, and the parties will negotiate a
              reasonable arrangement, including administrative costs, if any,
              for such escorted access.

4.2.4         PACIFIC may not favor itself in granting access to a ROW, conduit
              or pole attachment. PACIFIC shall not deny a request from CLEC for
              access to a ROW, conduit or pole attachment on the basis that such
              space is reserved for PACIFIC's future business needs, except as
              provided in Sections 4.2.5, 4.2.5.1 and 4.2.6.

4.2.5         PACIFIC may reserve capacity for projects for which it has

              activities within six (6) months after the date of CLEC's request
              or within eighteen (18) months after the date of CLEC's request if
              PACIFIC can demonstrate a definitive schedule for completion of
              the project with eighteen (18) months and that it is not possible
              to commence construction within six (6) months due to action
              required by others.

4.2.5.1       At CLEC's request in the event PACIFIC denies an CLEC request for
              access pursuant to Section 4.2.5, the parties shall supply to each
              other within thirty (30) days of the denial, subject to Section 18
              of this Agreement, copies of their respective engineering studies
              relating to the disputed space. PACIFIC shall prevail in its
              denial of space to CLEC only if PACIFIC's engineering studies have
              the same or greater level of detail and completeness as CLEC's
              studies. The parties shall meet and confer in an effort to reach
              an agreement that PACIFIC's engineering studies meet this
              standard. If the parties fail to agree, either Party may invoke
              the alternative dispute resolution process set forth in Attachment
              3.

4.2.6         The duties of PACIFIC described in Sections 4.2.5 and 4.2.5.1
              shall be subject to expansion or contraction in accordance with
              rules adopted by the Commission that constitute regulation of
              rates, terms and conditions for pole attachments within the
              meaning of Section 224(c)(3) of the Act.

              maintenance purposes.

4.2.8         In cases where PACIFIC reasonably believes that there is
              insufficient capacity to grant a request from CLEC for access to a
              ROW, conduit or pole attachment, PACIFIC must take all reasonable
              steps to accommodate CLEC's request and explore potential
              accommodations in good faith with CLEC.

4.2.9         In the event of an emergency affecting ROW, conduit or pole
              attachments made available by PACIFIC to CLEC, PACIFIC shall
              follow the mutually agreed upon Emergency Restoration Procedures
              attached to the Attachment 10 as Exhibit A.

4.2.10        PACIFIC shall provide to CLEC the names, numbers of the regional
              Single Points of Contact (SPOC) for administering all structure
              lease and ROW agreements within each defined geographical area.

4.3           APPLICATIONS FOR SPACE

4.3.1         PACIFIC will accept or reject in writing as soon as possible, but
              in any event within forty-five (45) days, CLEC's written request
              for access to PACIFIC's conduit or poles. PACIFIC's failure to
              respond within that time period shall be deemed a rejection of
              CLEC's request.

4.3.2         If PACIFIC denies an application by CLEC for conduit or pole
              space, its denial must be specific, and include all relevant
              evidence or information supporting the denial.

4.4           REQUESTS FOR DRAWINGS

4.4.1         At CLEC's request, PACIFIC shall provide CLEC with detailed
              engineering records and drawings of conduit, poles and other ROW
              paths in selected areas as specified by CLEC within a reasonable
              time frame.

                                                                         Page 11



4.4.2         PACIFIC shall allow personnel designated by CLEC to examine
              conduit system or pole line diagrams at PACIFIC's offices,
              provided that, for security reasons, a separate room is available
              for such examination. PACIFIC will make copies of such prints for
              CLEC at CLEC's expense, or a mutually agreed upon third party will
              be permitted to examine the diagrams.

4.5           PRE-ORDER REQUESTS FOR INFORMATION

4.5.1         CLEC may submit a written request for information to PACIFIC
              before submitting an application for conduit or pole space in a
              specified location.

4.5.2         PACIFIC shall provide information regarding the availability and
              condition of conduit or pole attachments within ten (10) business
              days of CLEC's written request for a records based answer and
              twenty (20) business days of CLEC's request for a field based
              answer. In the event CLEC's written request seeks information
              about the availability of more than five (5) miles of conduit or
              more than five hundred (500) poles, PACIFIC shall (1) provide an
              initial response within ten (10) business days; (2) use reasonable
              best efforts to complete its response within thirty (30) business
              days; and (3) if PACIFIC is unable to complete its response within
              thirty (30) business days or if the parties are unable to agree
              upon a mutually satisfactory long time period for PACIFIC's
              response, PACIFIC will hire outside contractors at CLEC's expense,
              not to exceed PACIFIC's customary charge for the same work,
              provided that before proceeding with such outside hiring, PACIFIC
              shall provide to CLEC the contractor's work order and hourly rate.

4.5.3         CLEC shall have the option to be present at the field based survey
              and PACIFIC shall provide CLEC at least twenty-four (24) hours
              notice prior to start of such field survey. By prior arrangement,
              PACIFIC shall allow CLEC personnel, accompanied by a PACIFIC
              escort, to enter manholes and view pole structures.

4.6           MAKE READY WORK

4.6.1         PACIFIC shall complete the "make ready work" required on poles or
              within conduit to enable CLEC to install its facilities. This work
              shall be accomplished by PACIFIC at a reasonable cost within
              thirty (30) business days, except that if PACIFIC requires longer
              than thirty (30) business days or if the parties are unable to
              agree upon a mutually satisfactory longer time period for
              completion of the make ready work, outside contractors may be
              hired at CLEC's expense to do the work. In that event, PACIFIC and
              CLEC shall confer and agree which Party shall hire the
              contractors. If CLEC hires the contractors, they must meet
              PACIFIC's reasonable standards. If PACIFIC hires the contractors,
              before proceeding with the work, PACIFIC shall provide to CLEC the
              contractor's work order and hourly rate, which shall not exceed
              PACIFIC's customary charge for the same work.

                                                                         Page 12



4.7           POLE ATTACHMENTS

4.7.1         Pole Attachments will be placed in the space on the pole
              designated for communications use. This space is generally located
              below electric supply circuits and excludes the neutral space
              between the electrical and communication space.

4.7.2         PACIFIC shall not attach, or permit other entities to attach,
              facilities on existing CLEC facilities without CLEC's prior
              written consent, except that such consent shall not be required
              for attachments to facilities such as arms and brackets that are
              designed for more than one cable.

4.7.3         CLEC may, at its option, make pole attachments using CLEC or
              CLEC-designated personnel. CLEC shall follow the methods and
              procedures for making pole attachments set forth in Commission
              General Order No. 95 and any additional standards provided to CLEC
              by PACIFIC.

4.8           CONDUITS:

4.8.1         To the extent that space is available as reasonably determined by
              PACIFIC, PACIFIC shall provide CLEC space in manholes for racking
              and storage of cable and other materials as requested by CLEC on a
              nondiscriminatory, first-come; first-served basis.

4.8.2         PACIFIC shall remove any retired cable from its conduit at CLEC's
              expense within a reasonable period of time if necessary to make
              conduit space available for CLEC.

4.8.3         Upon prior notice to PACIFIC, CLEC may conduct maintenance
              procedures in conduit space leased from PACIFIC. PACIFIC may
              dispatch a PACIFIC technician at CLEC's expense to oversee CLEC's
              work.

4.8.4         PACIFIC shall not restrict, withhold or unreasonably delay any
              modifications to conduit systems necessary to allow access to
              and/or egress from such systems, provided that CLEC must obtain
              certification of a professional structural engineer for
              modifications to post-1960 structures ensuring that the
              modifications will not adversely impact the structural integrity
              of the manhole.

4.8.5         Subject to accepted industry safety and engineering standards,
              PACIFIC will permit manhole interconnections, breaking out of
              PACIFIC manholes and breaking out of PACIFIC conduit by CLEC.
              PACIFIC may not limit new duct entrances to pre-cast knockouts,
              provided that CLEC must obtain certification of a professional
              structural engineer for modifications to post 1960 structures
              ensuring that the modifications will not adversely impact the
              structural integrity of the manhole.

                                                                         Page 13



4.9           INNERDUCTS

4.9.1         PACIFIC will permit CLEC, on a first-come, first-served basis, to
              license the use of innerducts in ducts in which PACIFIC already
              occupies an innerduct as long as one spare innerduct for
              maintenance purposes remains available. If an innerduct licensed
              by CLEC becomes defective, CLEC may use the spare maintenance
              innerduct as long as CLEC repairs the defective innerduct for use
              as a new maintenance spare as soon as possible.

4.9.2         Where spare innerduct does not exist, PACIFIC shall allow CLEC to
              install innerduct in a spare PACIFIC conduit, provided that CLEC
              complies with applicable law and PACIFIC's construction standards.

4.10          Access to Private Easements

4.10.1        PACIFIC shall not block any third party assignment of ROW to CLEC.

4.10.2        To the extent space is available, PACIFIC shall provide access to
              ROWs it has obtained from a third party to CLEC on a
              nondiscriminatory, first-come, first-served basis, provided that
              any underlying agreement with such third party permits PACIFIC to
              provide such access, and provided that CLEC agrees to indemnify
              PACIFIC for any liability arising out of such access or use.

4.10.3        PACIFIC will, upon request by CLEC, grant CLEC access to any
              private easement held by PACIFIC, in a mutually agreeable form of
              sub-easement, assignment or other appropriate access. PACIFIC's
              charge for such access shall be a pro rata portion of (a) the
              charge paid by PACIFIC to the grantor of the easement and (b) any
              other documented administrative and engineering costs incurred by
              PACIFIC in obtaining the original easement, both of which shall be
              determined on a case-by-case basis and calculated by taking into
              account (i) the size of the area to be used by CLEC and (ii) the
              number of users of PACIFIC's easement. CLEC shall also pay the
              reasonable documented administrative cost incurred by PACIFIC in
              processing such requests for access.

4.11          DISPUTE RESOLUTION

4.11.1        If the parties are unable to agree on a matter involving access by
              CLEC to a ROW, conduit, innerducts, pole, entrance facility or
              private easement owned or controlled by PACIFIC, either Party may
              submit the matter to the dispute resolution process set forth in
              Attachment 3 to this Agreement or may invoke applicable dispute
              resolution procedures described in the Act and the FCC's First
              Interconnection Order, sections 1217 through 1231.

                          EMERGENCY RESTORAL PROCEDURES

GENERAL            In the event of an emergency, restoration procedures may be
                   affected by the presence of CLEC facilities in or on PACIFIC
                   structures. While PACIFIC maintains no responsibility for the
                   repair of damaged CLEC facilities (except under a special
                   maintenance contract), it must nonetheless control access to
                   CLEC structures if restoral of affected facilities is to be
                   achieved in an orderly fashion.

PRIORITIZING       Where PACIFIC and CLEC are involved in emergency restorals,
                   access to PACIFIC's structures will be controlled by
                   PACIFIC's Maintenance District Manager or his/her on-site
                   representative according to the following guidelines:

SERVICE DISRUPTIONS/OUTAGES


          -        While exercising its right to first access, PACIFIC should
                   grant nondiscriminatory access to all occupants in or on its
                   facilities and every effort should be made to accommodate as
                   many occupants as is reasonably safe. Therefore, reasonable,
                   simultaneous access will not be denied unless public or other
                   safety considerations would prohibit such access.

          -        Where simultaneous access is not possible, access will next
                   be granted according to longevity in/on the structure (i.e.,
                   first in time, first in right). Where longevity in the
                   structure cannot be ascertained, access will be prioritized
                   on a first come, first served basis.


SERVICE AFFECTING


          -        While exercising its right to first access, PACIFIC should
                   grant nondiscriminatory access to all occupants in or on its
                   facilities and effort should be made to accommodate as many
                   occupants as is reasonably safe. Therefore, reasonable,
                   simultaneous access will not be denied unless public or other
                   safety considerations would prohibit such access.

          -        Where simultaneous access is not possible, access will next
                   be granted to occupants according to the level of damage to
                   its facilities and the likelihood that damage will result in
                   service disruption. Where likelihood that damage will result
                   is not clearly discernible, access will be granted according
                   to longevity in/on the structure (i.e., first in time, first
                   in right).

          -        Where longevity in the structure cannot be ascertained,
                   access will be prioritized a first come, first served basis.


POINT OF CONTACT   When an emergency situation arises which necessitates CLEC
                   access to a manhole after PACIFIC's normal business hours,
                   CLEC should call PACIFIC's Emergency Control Center (ECC).
                   All calls during normal business hours must be directed to
                   the appropriate PACIFIC Single Point of Contact (SPOC). For
                   after-hours calls, PACIFIC's ECC will contact the Maintenance
                   Center responsible for after-hours coverage of the affected
                   area. The maintenance supervisor contacted by the ECC will
                   return CLEC's call and will arrange for access with on-call
                   maintenance field personnel during the emergency condition.

1.       As used in this Agreement, Remote Switching Module or "RSM" means
         telecommunications equipment that provides switching network, line and
         trunk interfaces, and the capability to perform call processing when
         isolated from a required host switch. The "host switch," which must be
         provided by CLEC but not in Pacific's premises, is linked to and
         controls the RSM, and provides customer feature control, interoffice
         trunking, NPA-NXX routing and coordination of one or more RSMs.

2.       RSMs shall be placed exclusively for the purpose of access to Pacific
         unbundled network elements purchased by CLEC. No RSM shall be used to
         perform switching other than between lines served directly by the RSM,
         and between the RSM and its host switch located on CLEC premises. No
         direct trunks may be established between the RSM and another carrier's
         switch(es). Further, RSMs shall not be used to provide "information
         services" or "enhanced services," as those terms have been defined by
         applicable federal statutes and decisions, including those of the FCC.

3.       CLEC shall not be permitted to install its own power plant for use in
         connection with collocated RSM equipment. CLEC shall obtain all
         necessary AC or DC power feeds from Pacific according to the terms set
         forth in Schedule Cal P.U.C No. 175-T, Section 16.4. Any power
         requirements beyond those provided for in the above tariff shall be
         provided by Pacific to CLEC on an individual case basis.

4.       Pacific shall not be obligated to monitor any alarms installed by CLEC,
         other than environmental alarms (i e.: those that monitor conditions of
         the equipment room, rather than the RSM itself).

5.       CLEC's RSM equipment shall be grounded in such a manner as to insure
         that such equipment shall cause no harm nor interference with Pacific
         network facilities and equipment.

6.       CLEC shall list all RSMs it intends to place in its physical
         collocation space pursuant to this Agreement on each Application for
         Physical Collocation. Because of space limitations RSM collocation is
         not permitted in Shared Space collocation arrangements.

7.       The placement of RSMs in physical collocation space shall comply fully
         with all applicable physical co!location technical publication(s)
         referenced in the Interconnection Agreement.

8.       In no event shall Pacific be obligated to provide access for the RSM
         and equipment described herein or substantially similar facilities in a
         virtual collocation arrangement, whether under contract, tariff or
         otherwise. The Parties agree that this RSM Agreement does not
         constitute, and shall not be asserted to constitute, an admission or
         waiver or precedent with any state commission, the FCC, any other
         regulatory body or any court, or in

         any other forum that Pacific has agreed or acquiesced that the RSM
         equipment addressed in this Agreement is "equipment necessary for
         interconnection or access to unbundled network elements" under 47
         U.S.C. Section 251(c) (6). Pacific understands and agrees that CLEC
         remains free to argue that RSM equipment, in general, is "equipment
         necessary for interconnection or access to unbundled network elements"
         under 47 U.S.C. Section 251(c) (6).

9        Pacific shall have the right, upon 5 business days notice to CLEC, to
         inspect CLEC' physical and software configuration of CLEC's RSM for
         purposes of confirming CLEC's compliance with the terms of this RSM
         agreement. CLEC shall cooperate and provide information as requested by
         Pacific to assist with the purposes of this inspection. Any dispute
         concerning such inspections, or Pacific's right to any particular

                           PROVISIONING AND ORDERING

1.   NETWORK DEPLOYMENT

     Throughout the term of this Agreement, the quality of the technology, 
     equipment, facilities, processes and techniques (including, without 
     limitation, such new architecture, equipment, facilities, and interfaces 
     as PACIFIC may deploy) that  PACIFIC provides to CLEC under this 
     Agreement must be at least equal in quality to that provided by PACIFIC to 
     itself.

2.   GENERAL PROVISIONING REQUIREMENTS

2.1  Subject to the requirements of Attachment 6, CLEC may order Network 
     Elements either individually or in any combination. Combinations 
     ("Combinations") consist of multiple Network Elements to enable CLEC to 
     provide service in a geographic area or to a specific customer and that 
     are placed on the same order by CLEC. To the extent that Combinations or 
     unbundled Network Elements are related and logically associated with one 
     another, Combinations may be ordered with a single order.

2.2  Combinations shall be identified and described by CLEC in this Agreement,
     so that they can be ordered and provisioned together and shall not require 
     the enumeration of each Network Element within that Combination on each 
     provisioning order.

2.3  PACIFIC shall provide all provisioning services to CLEC during the same 
     business hours that PACIFIC provisions similar services for its end user 
     customers. Currently, those hours are Monday through Friday from 8:00 a.m. 
     to 5:30 p.m. PST. CLEC may request PACIFIC to provide Sunday, holiday, 
     and/or off-hour provisioning services. If CLEC requests that PACIFIC 
     perform provisioning services at times or on days other than as 
     required in the preceding sentence, PACIFIC shall provide CLEC a quote for 
     such services, consistent with PACIFIC's rates and terms for similar 
     services to PACIFIC's end user customers, at the rates set forth in 
     Attachment 8. If CLEC requests any service for which a quote is not set 
     forth in Attachment 8, PACIFIC will provide CLEC a quote based on state 
     wide average rates for the services performed. If CLEC accepts PACIFIC's 
     quote, PACIFIC shall perform such provisioning services.

2.4  PACIFIC's LISC is the Single Point of Contact (SPOC) for all ordering 
     contacts and order flow involved in the purchase of Network Elements or 
     Combinations. The SPOC shall provide an electronic  interface twenty-four 
     (24) hours a day, seven (7) days a week for all ordering order flows at 
     parity with that PACIFIC provides to itself or affiliates. Currently, 
     several systems

                                                                        10/16/98

                                                                          Page 2


     are less than twenty-four (24) hours per day, seven (7) days per week. 
     These systems, without limitation, and their current hours, are as follows:

          1.   CESAR/CLEO, Monday through Friday, 7:00 a.m. to 11:00 p.m.,
               Saturday 7:00 a.m. through 5:00 p.m.;

          2.   PREMIS, Monday through Saturday, 6:00 a.m. through 11:00 p.m.;

          3.   BOSS, Monday through Saturday, 6:00 a.m. through 11:00 p.m.;

          4.   SORD, Monday through Friday, 6:00 a.m. through 11:00 p.m.,
               Saturday 6:00 a.m. through 7:00 p.m.;

          5.   Scheduled Maintenance, one Sunday per month;      

          6.   Scheduled changes to all systems, e.g., CESAR, 7:00 p.m. every
               third Wednesday, etc.

2.5  The SPOC shall also provide to CLEC a toll-free nation-wide telephone 
     number (operational during the same hours as PACIFIC provides to its own 
     end user customers, currently from 8:00 a.m. to 5:30 p.m., Monday through 
     Friday) which will be answered by capable staff trained to answer 
     questions and resolve problems in connection with the provisioning of 
     Local Service, Network Elements or Combinations.

2.6  PACIFIC and CLEC shall mutually agree upon interface contingency and 
     disaster recovery plans for the ordering and provisioning of Local 
     Service, Network Elements or Combinations.

2.7  PACIFIC will recognize CLEC as the customer of record of all Network 
     Elements or Combinations ordered by CLEC and will send all notices, 
     invoices and pertinent information directly to CLEC.

3.   SPECIFIC PROVISIONING PROCESS REQUIREMENTS

3.1  Subject to Attachment 6, when CLEC orders the LSNE (either individually or 
     as part of a Combination), CLEC may also obtain all currently deployed 
     features and functions from the specified PACIFIC switch. If CLEC requests 
     a feature or function that is technically available but not deployed in a 
     particular switch, PACIFIC shall provide CLEC a quote pursuant to Section 
     1.6 of Attachment 6. If CLEC accepts the quote, Pacific shall deploy the 
     feature pursuant to the time frames and charges set forth in the quote. In 
     the event that the Parties cannot agree on the deployment of, or price for 
     such features, CLEC may seek Alternative Dispute Resolution pursuant to 
     Attachment 3 of the Agreement.

3.2  When requested by CLEC and at CLEC's option, Pacific will schedule 
     installation appointments (PACIFIC employee dispatch) with PACIFIC's 
     representative on the line with CLEC's representative or provide CLEC
     access

 
<PAGE>   135
                                                                   Attachment 11
                                                                          Page 3

        to Pacific's scheduling system through a mutually agreed upon
        Electronic Interface. PACIFIC will provide appropriate training to all 
        PACIFIC employees who may communicate, either by telephone or 
        face-to-face, with CLEC Customers. Such training shall instruct the 
        PACIFIC employees not to disparage or discriminate against CLEC, its 
        products or services and shall comply with the branding requirements of 
        this Agreement.

3.3     Upon request from CLEC, PACIFIC will provide an intercept referral 
        message for LSNE that includes any new CLEC telephone number, for 
        residential customers for three (3) months, and business customers for 
        twelve (12) months, and PACIFIC will provide directory updates at the 
        next publication. This intercept referral message shall be approved by 
        CLEC and shall be similar in format to the intercept referral messages 
        currently provided by PACIFIC for its own end-users. Custom messages or 
        extension in duration of the referral shall be subject to the charges 
        set forth in Attachment 8.

3.4     PACIFIC will provide CLEC with a Firm Order Confirmation (FOC) for each 
        order, within four (4) Business hours of PACIFIC's receipt of each 
        accurate and complete electronically submitted order. In the absence of 
        an electronically submitted order, the time frame for a FOC for 
        manually received orders will be as mutually agreed. In the case of a 
        Network Elements or Combinations, the FOC must contain an enumeration 
        of CLEC's ordered Network Elements or Combinations (and the specific 
        PACIFIC naming convention applied to that Network Element or 
        Combination), features, options, physical interconnection, quantity, 
        and PACIFIC commitment date for order completion (Committed Due Date).

3.5     Upon completion of the order, PACIFIC will provide CLEC electronically 
        (unless otherwise notified by CLEC) with an Order Completion per order 
        that states when that order was completed. PACIFIC shall respond with 
        specific order detail as enumerated on the FOC and shall state any 
        additional charges (e.g. Time and Cost charges) up to a previously 
        agreed upon limit associated with that order.

3.6     For new Network Elements developed based on Section 1.6 of Attachment 
        6, the Parties will mutually agree on the testing to be used.

3.7     When CLEC electronically orders a Local Service, Network Element or 
        Combination, PACIFIC shall provide notification electronically of any 
        instances when (1) PACIFIC's Committed Due Dates are in jeopardy of not 
        being met by PACIFIC on any Network Element or feature contained in any 
        order for Local Service, Network Elements or Combinations or (2) an 
        order contains Rejections/Errors in any of the data element(s) fields. 
        Such notice will be made as soon as the jeopardy or reject is 
        identified. When NDM or EBI is available and CLEC elects to place a 
        manual order, PACIFIC may notify

<PAGE>   136

                                                                   Attachment 11
                                                                          Page 4


       CLEC of a jeopardy or reject condition via facsimile or telephone call to
       the CLEC contact identified on the order. In all cases, PACIFIC shall
       concurrently indicate its new committed due date.

3.8    At CLEC's request, PACIFIC will perform co-operative testing with CLEC 
       (including trouble shooting to isolate any problems) to test Local 
       Service. Network Elements or Combinations purchased by CLEC in order to 
       identify any performance problems identified at turn-up of the service.

3.9    PACIFIC shall inform CLEC if a customer action results in a reassignment 
       of an AIN trigger from an CLEC AIN application to some other service 
       provider's application. Such notification shall be completed within 
       twenty-four (24) hours of the action via electronic interface as 
       described in the Account Maintenance requirements specified in this 
       Attachment.

3.10   Testing of AIN based services in PACIFIC's AIN test laboratory will 
       identify feature interactions with existing switch-based or other types
       of services. PACIFIC will provide CLEC with a list of feature 
       interactions uncovered during testing of any services. Disclosure of 
       feature interactions to CLEC's end user will be CLEC's sole 
       responsibility.

3.11   PACIFIC shall provision correct AIN triggers based on services ordered 
       by CLEC on its provisioning order.

4.     GENERAL ORDERING REQUIREMENTS

4.1    Upon CLEC's request through a Suspend/Restore Order for LSNE or a 
       Combination containing LSNE, PACIFIC shall suspend or restore the 
       functionality of any Network Element or Combination to the extent 
       technically feasible. PACIFIC shall implement any restoration priority 
       on a per Network Element or Combination basis in a manner that conforms 
       with CLEC requested priorities and any applicable regulatory policy or 
       procedures. The charges for a Suspend/Restore are set forth in 
       Attachment 8.

4.2    PACIFIC shall provide to CLEC the functionality of blocking calls (e.g., 
       900, 976 or international calls) by line.

4.3    Subject to Section 271(e)(2)(B), when intraLATA presubscription is 
       permissible in California, when ordering a local Switching Element, CLEC 
       may order from PACIFIC separate interLATA and intraLATA routing (i.e., 2 
       PICs where available) on a line.

4.4    As directed by CLEC, when CLEC orders a Network Element or Combination, 
       all pre-assigned trunk or telephone numbers currently associated with 
       that Network Element or Combination shall be retained, if directed by 
       CLEC, without loss of feature capability and without loss of associated 
       ancillary

                                                                   Attachment 11
                                                                          Page 5


     functions including, but not limited to, Directory Assistance and 911/E911 
     capability, unless technically infeasible.

4.5  When CLEC orders Network Elements or Combinations that are currently 
     interconnected and functional, such Network Elements and Combinations will 
     remain interconnected and functional without any disconnection or 
     disruption of functionality. This shall be known as Contiguous Network 
     Interconnection of Network Elements. There shall be no additional charge 
     for such interconnection.

5.   ORDERING INTERFACES

5.1  PACIFIC shall provide to CLEC an Electronic Interface (EI) for 
     transferring and receiving orders, FOCs Service Completions, and other 
     provisioning data and materials as set forth in Appendix C and at the 
     rates set forth in Attachment 8.

5.2  When ordering LSNE, subject to the implementation schedule in this 
     Agreement, CLEC's representatives will have real-time access to PACIFIC 
     customer information systems which will allow the CLEC representatives to 
     perform the following tasks:

          1.   Obtain customer profile, including customer name, billing and 
               residence address, billing telephone number(s), and 
               identification of features and services subscribed to by 
               customer. Such access shall be governed by Sections 5.5.1.1 and 
               5.5.1.2 of Attachment 5 to this Agreement, depending on whether 
               the information accessed is for a residence or business customer.

          2.   Obtain information on all features and services available, in

          9.   Suspension, termination, or restoral of service where 
               technically feasible."

6.   PACIFIC PROVISION OF INFORMATION

6.1  PACIFIC shall provide to CLEC upon request:

     1.   A list of all services and features technically available from each 
          switch that PACIFIC may use to provide a Local Switching Element, by 
          switch CLLI;

     2.   A listing by street address detail, of the service coverage area of 
          each wire center;

     3.   All engineering design and layout information for each Network 
          Element or Combination, in response to an order for the Network 
          Element or Combination;

     4.   A listing of all technically available functionalities for each 
          Network Element or Combination, in response to an order for the 
          Network Element or Combination;

     5.   As long as PACIFIC remains the code administrator for California, 
          notice of any NPA relief planning meetings so that CLEC may 
          participate in those meetings to reach industry consensus on NPA code 
          relief.

7.   ORDER FORMAT AND DATA ELEMENTS FOR INDIVIDUAL NETWORK ELEMENTS AND 
     COMBINATIONS

7.1  In ordering Network Elements or Combinations, CLEC and PACIFIC will 
     utilize standard industry order formats and data elements developed by the 
     Alliance for Telecommunications Industry Solutions (ATIS), including 
     without limitation the Order and Billing Forum (OBF). Industry standards 
     do not currently exist for the ordering of all Network Elements or 
     Combinations. Therefore, until such standard industry order formats and 
     data elements are developed by the ATIS for a particular Network Element 
     or Combination, CLEC and PACIFIC will mutually agree to a format to be 
     used to address the specific data requirements necessary for the ordering 
     of those Network Elements or Combinations. There currently exist OBF 
     formats for INP and the following Network Elements: Links, Ports, and 
     Transport. When an ATIS standard or

<PAGE>   139
                                                                   Attachment 11
                                                                          Page 7

        format is subsequently adopted, the Parties will use such standard or
        format in lieu of any standard or format set forth in this Attachment,
        unless the Parties mutually agree to continue to use the standard or
        format set forth herein.

7.2     CLEC and PACIFIC shall agree upon the appropriate ordering and 
        provisioning codes to be used for each Network Element or Combination. 
        These codes shall be known as data elements.

7.3     Each order for a Network Element or a Combination will contain the 
        following order-level sections, as defined by the OBF or as mutually 
        agreed to by the Parties: Administration, Bill, Contact, and End User 
        Information, e.g., Local Service Request (LSR) form, Access Service 
        Request (ASR) form, End User Information (EU) form.

7.4     CLEC will provide provisioning data in the format defined below when 
        ordering Network Elements or Combinations. First, CLEC will state 
        whether it is ordering a Network Element (one or more of the Network 
        Elements described in this Agreement) or a Combination (multiple 
        Network Elements in the same order). CLEC will then provide data in the 
        following provisioning categories, such data to be provided on the OBF 
        ordering form as completed data fields:

        1.      Activity. The activity field will comply with OBF standards, 
                which currently include Add, Change, Disconnect and Record Only.

                Order Activity Description. For each activity, a further 
                description of the Order Activity may be required. Consistent 
                with OBF standards, Modify, Cancel, Expedite, Coordinated, 
                Suspend and Restore. The preceding Order Activity Descriptions 
                may be applied to any Add, Change, Disconnect or Record Only 
                order. In some cases, more than one of these may apply to a 
                particular order. In addition, Sequence, as defined below, may 
                be added:

                Sequence: The Parties will jointly develop the sequence that 
                will apply when components of the order must be worked in the 
                proper sequence, or when components of the order are 
                sequentially related to components or another order.

        2.      Purpose of Order. The Purpose of Order will contain a brief 
                statement describing the overall purpose of the order (e.g., 
                Add new ISDN loop or build dedicated trunking/transport from 
                local end office to CLEC OSPS 5E).

        3.      Type of Network Element or Combination. The Type of Network 
                Element or Combination category consists of two parts. First, 
                an E (Network Element) or C (Combination) followed by a dash 
                and then the two character code for the Network Element(s) 
                (e.g., E-LS (Local Switching) and C-DT/LS (Combination of 
                Dedicated

          SL   Signaling Link Transport

          DB   SCPs/Databases (LNP, LIDB, Toll Free)

          TS   Tandem Switching

     The parties will mutually agree on the proper Type of Network Element or
     Combination designators for other Network Elements or Combinations, e.g.,
     Operator Services, Directory Services, etc.

4.   Interconnection Locations. This category describes the beginning and
     end-point of the Network Element or Combination. For example, the point of
     termination (POT) may be listed as a switch CLLI, a frame tie down
     location, a channel on a T3, or a customer address. Various types of POT
     are described in the tables shown in Appendix A.

5.   Interconnection Specific. The Interconnection Specific category describes
     the nature of the interconnection and the appropriate relationships within
     the Network Element/Combination. The appropriate type of Interconnection
     Specific is described for each Network Element/Combination in the tables
     shown in Appendix A. The following definitions apply:

     Contiguous: All cross-connects, muxing, cross-office ties, etc. will be
     included between the two interconnection points listed under
     Interconnection Locations so that the Network Element or Combination is
     delivered fully functional.

     Routing: Indicates that routing is party of the necessary interconnection.

     Functionally Inclusive: All functionality as it is defined within
     Attachment 6 of this Agreement as it relates to interconnection 
<PAGE>   141
                                                                   Attachment 11
                                                                          Page 9

                when the Network Element or Combination is provisioned by
                PACIFIC.

        6.      Element Identification. This field includes the precise
                identifier of the Network Element. For example, the identifier
                can be a circuit ID, facility name, switch CLLI, or Working
                Telephone Number.

        7.      Object. The Object identifies the basic unit of the Network
                Element or Combination. Examples include Network Trunk (for the
                Network Element LS) and DS1 (for the Network Element DT). The
                Objects related specifically to each Network Element or
                Combination are provided in the tables shown in Appendix A.

        8.      Quantity/Capacity. This field lists the Quantity/Capacity of
                Objects. For example, for the Local Loop the number "1" in this
                field would indicate that one Local Loop was being ordered. On
                the other hand, for the Object "DT" the number "4" would
                indicate that a capacity of 4 DS1 are being ordered.

        9.      Options. For each Object, there may be numerous Options. This
                category identifies the specific Option of the selected Object.
                In most case, only one Option applies for each Object. The
                specific Options for each Object are contained as shown in
                Appendix A. Examples include 2-wire (for the Object Analog
                Loop), DID (for the Object Customer Trunk) and ESF (for the
                Object DS1).

        10.     Characteristics. For each Option, there may be multiple
                Characteristics that require additional details. This category
                identifies those Characteristics, along with the necessary
                details. The appropriate type of Characteristics are described
                for each Network Element or Combination within the tables shown
                in Appendix A. Examples include ISDN conditioned (for the Option
                2-wire) and TSG (for the option DID).

        11.     Features. This field identifies the Features specific to the
                Network Element/Combination. For example, when the Network
                Element is Local Switching, the CLASS/LASS features would be
                included in this category. CLEC will direct PACIFIC which of
                these features to activate for a specific customer.

        12.     Desired Due Date. This field identifies the date the entire
                order is expected to be completed.

        13.     Due Date Detail. If required, this field identifies interim
                dates (for Combinations where the network Element Due Dates
                differ), and the relationship between the provisioning
                activities internal to the order, and those provisioning
                activities outside the order that may be related. Coordination
                and sequencing requirements will be reflected in this field.
<PAGE>   142
                                                                   Attachment 11
                                                                         Page 10



          14.  Remarks. This field will include any remarks that are related to
               the provisioning order that are not reflected elsewhere.

7.5       When ordering a Network Element (individually or as part of a
          Combination), the interconnection and functionality internal to that
          Network Element will not be specifically ordered by CLEC and will
          automatically be provided by PACIFIC. For example, when ordering the
          element DT (Dedicated Transport), the use of Digital Cross Connects
          that might be necessary to provide the connectivity between two
          interconnection locations will not be described on CLEC's order.

7.6       Examples of the provisioning or OBF format to be used by CLEC when
          ordering certain provisioning activities for individual Network
          Elements are shown in Appendix B.

7.7       CLEC may purchase Network Elements either individually or in
          combinations. Combinations of Contiguous Network Elements can be
          ordered (i) on a case-by-case basis for those Network Elements that
          are customer-specific; or (ii) on a common-use basis for those Network
          Elements that are shared by multiple customers.

7.8       When ordering either customer-specific or common-usage Combinations,
          CLEC may specify the functionality of that Combination without the
          need to specify the configuration of the individual Network Elements
          needed to perform that functionality. For example: CLEC may also
          choose to purchase from PACIFIC a Local Loop and Switching Combination
          which would be comprised of the Loop and Network Element LS (Local
          Switching). This Combination would allow CLEC to purchase switching
          features/such as Class features) and functionalities on a per-customer
          basis.

7.9       Prior to providing local service using unbundled Network Elements or
          Combinations in a specific geographic area or when CLEC requires a
          change of network configuration, CLEC may place an order with PACIFIC
          requiring PACIFIC to prepare certain common-usage elements and
          functionalities for CLEC. CLEC has identified one possible set of
          these elements and functionalities as the Local Switching Conditioning
          Combination. This Combination may be comprised of all or some of the
          following individual Network Elements: LS (Local Switching), CT
          (Common Transport), SS (Signal Transfer Points), DB (SCPs/Databases)
          and TS (Tandem Switching). In order to provide these Network Elements
          and their respective functionalities to CLEC, Pacific shall prepare
          its network for CLEC's use of these common elements by readying each
          necessary switch.

7.10      CLEC may also use unbundled Network Elements to originate and
          terminate toll traffic. CLEC has identified the following two
          Combinations which will allow such functionality: Toll Traffic
          Combination 1, which is comprised of the
<PAGE>   143
                                                                   Attachment 11
                                                                         Page 11



      Network Elements DT (Dedicated Transport) and LS (Local Switching); and
      Toll Traffic Combination 2, which is comprised of DT (Dedicated
      Transport), TS (Tandem Switching), CT (Common Transport) and LS (Local
      Switching).

7.11  There are many additional Combinations which CLEC may choose to order from
      PACIFIC.

8.    PERFORMANCE REQUIREMENTS

8.1   CLEC will specify on each order its Desired Due Date (DDD) for completion
      of that particular order. Standard intervals do not apply to orders under
      this Agreement. PACIFIC will not complete the order prior to the DDD or
      later than the DDD unless authorized by CLEC. If the DDD is less than the
      following Network Element intervals, the order will be considered an
      expedited order.

</TABLE>

8.2   Within two (2) business hours after a request from CLEC for an expedited
      order, PACIFIC shall notify CLEC of PACIFIC's confirmation to complete, or
      not complete, the order within the expedited interval. A Business Hour is
      any hour occurring on a business day between 8:00 a.m. and 5:00 p.m. PST.
<PAGE>   144
                                                                   Attachment 11

8.3   Once an order has been issued by CLEC and CLEC subsequently requires a new
      DDD that is less than the minimum interval defined, CLEC will issue an 
      expedited modify order. PACIFIC will notify CLEC within two (2) Business 
      Hours of its confirmation to complete, or not complete, the order 
      requesting the new DDD.

8.4   CLEC and PACIFIC will agree to escalation procedures and contacts. 
      PACIFIC shall notify CLEC of any modifications to these contacts within 
      one (1) week of such modifications.

8.5   PACIFIC shall satisfy the following performance standards: (i) at least 
      90% of all orders must be completed by DDD; (ii) at least 98% of all 
      orders must be completed by Committed Due Date; and (iii) at least 99% 
      of all orders will be completed without error.

8.6   CLEC will pay for all additional cost for performance in excess of 
      PACIFIC's intervals for comparable services.

9.    ACCOUNT MAINTENANCE

      PACIFIC AND CLEC agree to the following account maintenance procedures:

9.1   OUTPLOC Transaction Feed

      OUTPLOC means when an CLEC Local Service or LSNE changes from CLEC local
      exchange service to another local exchange carrier. Until approved
      industry standards are available, PACIFIC will notify CLEC using a 9270
      CARE-like electronic record when a customer changes from CLEC Local to a
      new Local Service Provider. PACIFIC will provide 9270 CARE-like records
      six (6) days a week, Monday through Friday (Saturday (when change activity
      occurs)), via the CONNECT: Direct interface. Electronic records will be
      sent within twenty-four (24) hours of the switch being provisioned for
      the customer change. CLEC understands that PACIFIC may send other
      9000 series CARE-like electronic records on CLEC Local customers.

9.2   Change Request Implementation

      PACIFIC will cease billing CLEC effective as of the date of the 
      customer's change request. If there is a delay in PACIFIC's 
      implementation of the customer's change request, PACIFIC will issue a 
      credit to CLEC for any amounts billed to CLEC with respect to that 
      customer following the date of the customer's change request.

9.3   Use of Service Order for PIC-Only Change
<PAGE>   145
                                                                   Attachment 11
                                                                         Page 13


      When an CLEC Local Customer contacts CLEC Local only to request a change
      of Primary Interexchange Carrier (PIC) from one IEC to another IEC,
      PACIFIC will accept the PIC-only change request from CLEC Local on the
      current service order feed. PACIFIC will change its current tariffed rate
      applicable to PIC-only changes.

9.4   IEC PIC Change Request

      PACIFIC will not accept a PIC change request from a Long Distance carrier
      for CLEC Local customers. Beginning December 1996, PACIFIC will return
      such requests to the IEC indicating CLEC's Operating Company Number (OCN)
      on the industry standard 3148 record.

The Unbundled Network Elements Service Request Form will be sent with every UNE
and TSR order and is divided into three sections: the Administrative Section,
the Bill Section, and the Contact Section.

The Administrative section is always required and contains such information as
the purchase order number, desired due date, activity, expedite, and related
order numbers.

The Billing section designates the CLEC Billing Account number to be used by the
ILEC and the CLEC billing name and address. This field is to be filled out on
all orders.

The Contact section contains contact information for the Initiator of the order,
the Implementation contact, the design contact, and maintenance contact. For
Loop and Switch orders only the initiator contact person is to be designated,
for Infrastructure provisioning, or customer orders for such things as dedicated
transport, the implementation and design contacts are to be specified.

                           END USER INFORMATION FORM

The End User Information form is sent with every UNE and TSR customer order is 
used for ordering specific network elements or TSR to provide service for a 
specific customer. It is divided into 5 parts: the Administrative Section, the 
Location and Access Section, the Inside Wiring Section, the Bill Section and 
the Per Customer Element Section.

The Administrative section is used to link subsequent forms to the Unbundled 
Network Element Form. The information in this section is on all of the forms 
that are used for ordering Unbundled Network Elements, either on a footprint 
basis or on an individual customer basis. The Administrative Section contains 
five fields which are required on all forms, these field are: Customer Carrier 
Purchase Order Number (PON), version (VER), Local Service Request Number (LSR 
NO), quantity (QTY), and the page number of (PG_of_). The Administrative 
section will not be discussed on further forms.

The Location and Access form contains the customer name and Address and any 
specific instruction need to access the customer equipment. This section is 
required on all customer orders. The information on this section would be used 
for data base entries such as E911 or DA as well designating the location of 
any customer premises work.

Inside wiring is not an Unbundled Network Elements but is included here for
completeness. This section needs to be filled out only if the ILEC is the inside
wiring vendor. This section is also included to be consistent with the existing
OBF forms. The Bill Section contains the local billing account number and
information for the billing contact.

The Per Customer Network Element Section contains a listing of the specific
Network Elements which are being ordered to serve a specific customer and an
indication of any attached forms which are need for additional information
concerning the ordered Network Elements. Possible customer specific elements
are, the NID, Loop, and Local Switching. The need to provision customer specific
data base information would also be indicated here.

               PRINCIPALS FOR IMPLEMENTING ELECTRONIC INTERFACES
                         FOR OPERATIONAL SUPPORT SYSTEMS

1.       PREORDERING

1.1      Transaction-Based Information Exchange

The Parties agree that preordering information exchange will be transmitted over
the same interface according to the same content definition both for resold
PACIFIC services provided using UNE.

1.2      Initial Systems

CLEC will utilize various manual methods of preordering information exchange.

1.3      Long Term Systems

As soon as possible after the effective date and no later than the "Detailed
Specifications Agreed To Date" as set forth in Exhibit 1, CLEC and PACIFIC will
use their best efforts to agree to detailed specifications for upgrading the
transaction based preordering information exchange mechanism according to the
CLEC proposed data model for preordering which is based on Telecommunications
Industry Forum (TCIF) for Electronic Data Interchange (EDI), Version 6. Unless
PACIFIC and CLEC agree to an alternative exchange mechanism by February 10,
1997, the specifications will require that EC-Lite/EDI formatted content be
transmitted over a mutually agreeable X.25 or TCP/IP based network to perform
inquiries, including inquiries for Switch/Feature Availability, Address
Verification, Telephone Number Assignment, Appointment Scheduling, and Customer
Service Record requests. When the "Detailed Specifications Agreed To Date" is
met, and no additional specifications or changes are required by law, PACIFIC
will implement this upgrade by the applicable "Start Date" specified in Exhibit
1.

CLEC and PACIFIC will translate preordering data elements used in their internal
processes into the agreed upon forms, and EDI.

1.4      Batch Data Exchange

Unless another mutually agreed to alternative exists between PACIFIC and CLEC,
CLEC will use two types of orders, the Infrastructure Provisioning order and
Customer Specific Provisioning order, to establish local service capabilities
based on a UNE architecture. The Infrastructure Footprint Form and associated

                                                                   Attachment 11
                                                                      Appendix C
                                                                          Page 2


ASR forms (Local Switching, Interoffice Transport, Signaling and Database,
Operator Services and DA, and Operations Systems). CLEC will provide these
Infrastructure Provisioning and ASR forms via the ASR process, including passing
the information over a file transfer network, (e.g. Network Data Mover Network)
using the CONNECT: Direct file transfer product.

Customer Specific provisioning will be based on OBF LSR forms and applicable
SOSC interpretations of transactions in accordance with OBF forms. PACIFIC and
CLEC agree to adapt interfaces based on evolving ATIS/OBF and SOSC standards.

2.       ORDERING AND PROVISIONING

2.1      CLEC Resells PACIFIC Telecommunications Service(s)

The exchange of information relating to the ordering and provisioning of local
service, when CLEC is the customer of record for the resold service(s), will be
based on the most current industry order formats and data elements developed in
the Ordering and Billing Forum (OBF).

2.1.1    Initial Systems

Except as provided in Exhibit 1. PACIFIC will provide CLEC, on or before the
Effective Date, with an electronic interface known as Resale Mechanized
Interface (RMI) for transmitting and receiving Service Requests and related
information such as Firm Order Confirmations (FOC, Jeopardies, Rejects, and
Completions). CLEC and PACIFIC will translate necessary data elements used in
their internal processes into mutually agreeable file formats and record
layouts. CLEC and PACIFIC will develop a mutually agreeable schedule for
transmissions throughout the day suing the CONNECT: Direct protocol.

For the ordering of products not supported by RMI, PACIFIC will provide CLEC
with other technologies mutually agreed to by the Parties.

2.1.2 Long Term Systems

As soon as possible after the Effective Date and no later than the "Details
Specifications Agreed to Date" as set forth in Exhibit 1, CLEC and PACIFIC will
use their best efforts to agree to detailed specifications for upgrading the
ordering information exchange mechanism according to the Telecommunications
Industry Forum (TCIF) for Electronic Data Interchange (EDI) CLEC and PACIFIC
mutually agree that the information exchange will be forms based, including the
use of the Local Services Request (LSR) Form, the End User Information Form and
the Resale Information Form developed by the OBF. CLEC and PACIFIC

                                                                          Page 3


will use a mutually agreeable X.25 or TCP/IP based transport network for
exchange of transactions. CLEC and PACIFIC will translate ordering and
provisioning requests originating in their internal processes into agreed upon
forms and EDI transactions. Provided that the "Detailed Specifications Agreed To
Date" is met and no additional specifications or changes in specifications are
required by law, PACIFIC will use its best efforts to implement this upgrade by
the applicable "Start Date" specified in Exhibit 1.

2.2      CLEC Provides Service Using PACIFIC Unbundled Network Elements

2.2.1    Ordering Process and Forms

CLEC and PACIFIC will use two types of orders, an Infrastructure Provisioning
order and a Customer Specific Provisioning order to order and provision Network
Elements and Combinations.

The Infrastructure Provisioning Footprint order notifies PACIFIC of the common
use (across CLEC Retail Customers) Network Elements and Combinations that CLEC
will require, and identifies the geographic area CLEC expects to serve through
the Network Elements and Combinations ordered. PACIFIC and CLEC will mutually
agree on necessary modifications to the existing ordering process and forms used
for Exchange Access products until the OBF has adopted an acceptable alternative
method. In addition PACIFIC will accept a modified version of the Translation
Questionnaire (TQ) Form adopted by the OBF. The modified TQ will be sent to
PACIFIC, and PACIFIC will modify the routing tables for its end offices to
accommodate the treatment of customer calling associated with the combination of
Network Elements and Combinations that CLEC is employing to deliver service.
CLEC will provide the Infrastructure Footprint Order and all associated ASR
forms. PACIFIC will accept delivery of the Infrastructure Provisioning Forms
through the ASR process.

The customer specific provisioning order will be based upon OBF LSR Forms.
PACIFIC agrees that the information exchange will be forms based using the Local
Service Request Form, End User Information Form, Loop Element Form (formerly
Loop Service form), and Switch Element Form (formerly Port Form) developed by
the OBF. Such customer specific elements include, but are no limited to, the
customer loop, the network interface device, the customer dedicated portion of
the local switch, and any combination thereof.

2.2.2.   Initial Systems

PACIFIC will provide CLEC, on the schedule specified in Exhibit 1 attached
hereto, with an Electronic Interface known as the Network Data Mover (NDM) for
transmitting and receiving Service Requests and related information such as

                                                                   Attachment 11
                                                                      Appendix C
                                                                          Page 4

Firm Order Completions (FOC), Jeopardies, Rejects, and Completions. CLEC and
PACIFIC will translate necessary data elements used in their internal processes
into mutually agreeable file formats and record layouts. CLEC and PACIFIC will
develop a mutually agreeable schedule for transmissions throughout the day using
the CONNECT: Direct protocol.

2.2.3   Long Term Systems

As soon as possible after the Effective Date and in no event after the "Detailed
Specifications Agreed To Date" as set forth in Exhibit 1 attached hereto. CLEC
and PACIFIC will use their best efforts to agree to detailed specifications for
upgrading the ordering information exchange mechanism according to the
Telecommunications Industry Forum (TCIF) for Electronic Data Interchange (EDI)
for the Customer Specific Provisioning orders. The information exchange will be
forms based. CLEC and PACIFIC will use a mutually agreeable X.25 or TCP/IP based
transport network for exchange of transactions. CLEC and PACIFIC will translate
ordering and provisioning requests originating in their internal processes into
the agreed upon forms and EDI transactions. Provided that the "Detailed
Specification Agreed To Date" is met and no additional specifications or changes
in specifications are required by law, PACIFIC will use its best efforts to
implement this upgrade by the applicable "Start Date" specified on Exhibit 1
attached hereto.

3.      TESTING AND ACCEPTANCE

CLEC and PACIFIC agree that no interface will be represented as either generally
available or as operational until end-to-end functionality testing, as agreed to
in a Joint Implementation Agreement or other mutually acceptable document are
completed to the satisfaction of both Parties. The intent of the end-to-end
functionality testing is to establish, through the submission and processing of
test scenarios, that transactions agreed to by CLEC and PACIFIC will
successfully process, in a timely and accurate manner, through both Parties'
support of OSS as well as the interfaces. CLEC will provide load forecasts by
transaction type. PACIFIC will provide documentation to assure ability to handle
forecasted load, such as system simulation models. The testing will include the
use of mutually agreeable test transactions, designed to represent no less than
95 percent of the transaction types that CLEC expects to send and receive
through the Interface undergoing end-to-end testing. In addition, CLEC and
PACIFIC will establish either a mutually agreeable testing environment or an
audit process sufficient to demonstrate that the interfaces established between
CLEC and PACIFIC have the capability and capacity to exchange busy period
transaction volumes reasonably projected to occur during the forward-looking
twelve month period following implementation of the interface. The test

can accept and process the anticipated busy period loan without degradation of
overall end-to-end performance of the information exchange delivered to CLEC
even when other CLEC transactions are simultaneously processed by PACIFIC.
Before testing begins, the Parties will mutually agree upon testing entrance
and exit criteria.

4.   JOINT IMPLEMENTATION AGREEMENT DEVELOPMENT


CLEC and PACIFIC recognize that this Attachment is not sufficient to fully
resolve all technical and operational details related to the interfaces
described. Therefore, CLEC and PACIFIC agree to document the additional 
technical and operational details in the form of a Joint Implementation 
Agreement (JIA).  The JIAs for each interface will become a legally binding 
addendum to this Attachment. These JIAs may be modified over the course of this 
Agreement without subjecting the balance of the Agreement to renegotiation or 
modification. Both Parties further agree that any technical, operational or 
implementation issues, once identified at the working team level, may be 
escalated by the initiative of either Party thirty (30) days after an issue is 
identified if no plan for resolution has been agreed.  The escalation will 
process first to the senior management of each company who will seek to resolve 
the issue. If an issue is not resolved within thirty (30) days following 
receipt of the issue by senior management, either Party may submit the issue to 
the dispute resolution procedures of Attachment 3 for binding resolution. In 
addition, CLEC and PACIFIC will document both a topical outline for the JIAs as 
well as establish a schedule for identifying, discussing, resolving and 
documenting resolution of issues related to each aspect of the JIA topical 
outline for each interface discussed in this document. In no case, will either 
end-to-end integrity testing or loan testing begin without both Parties 
mutually agreeing that each interface JIA documents the intended operation of 
the interface scheduled for testing. Any issues identified and subsequently 
resolved through either the end-to-end integrity or load testing processes will 
be incorporated into the impacted interface JIA within thirty (30) days of 
issue resolution.

1.2 INTRODUCTION

    1.2.1  This document establishes fundamental principles and actions for OSS 
    interface implementation and maintenance between Pacific Bell (hereafter 
    known as "Pacific") and CRL Network Services ("CLEC").

    1.2.2  Pacific and CLEC agree to jointly test and implement the interfaces
    that are outlined in Section 2.2. Scope, pursuant to the terms and
    conditions of the Interconnection Agreement between CLEC and Pacific dated
    December 19, 1996. Pacific will present project plans to CLEC specifying the
    technical, operational and other details regarding each such OSS interface
    and the timelines for testing and implementation thereof. CLEC shall have
    the opportunity to comment and make recommendations related to each such OSS
    interface and Pacific shall fully consider such comments and recommendations
    and respond to CLEC in a timely manner. If the parties cannot reach
    agreement regarding such OSS interface, the OSS Dispute Resolution process
    set forth in Section 4 hereof shall apply. In the event of any disagreement
    between the provisions of the Interconnection Agreement regarding OSS and
    this JIA, the terms of this Interconnection Agreement shall control.

2.   PURPOSE

2.1  PURPOSE AND OBJECTIVE

     2.1.1  The purpose of this JIA is to document the principles guiding the 
     technical and operational work efforts between Pacific and CLEC relative 
     to the implementation of OSS interfaces referenced in the Interconnection 
     Agreement and identified in Section 2.2, Scope.

     2.1.2  An objective of this JIA is to document the guidelines for 
     implementation and usage of the electronic interfaces under the terms of 
     the Interconnection Agreement. To achieve this objective, the parties will 
     use the documentation and processes referenced in this JIA and focus work 
     efforts on issues that increase the effectiveness of mechanized interfaces.

     2.1.3  This JIA is entered in accordance with Attachment 11 of the 
     Pacific/CRL Network Services Interconnection Agreement.

     2.1.4  To achieve the purpose and objective, the JIA establishes a basis 
     for work efforts and outlines the responsibilities of the parties. An 
     important part of this is the Change Control Process. This process is 
     established for the parties to manage modifications to the interfaces 
     subject to applicable guidelines developed within the Ordering and Billing 
     Forum (OBF) and the Telecommunications Industry Forum (TCIF). This Change 
     Control Process also provides for an escalation process. Supporting 
     documentation for each interface is maintained separately, outside of this 
     JIA. Issues and corresponding resolutions will be documented in 
     correspondence.

2.2  SCOPE

     This JIA pertains to the EDI ordering electronic application interface, 
     specific to Number Portability orders and the latest versions of the 
     associated interface control documents. A separate JIA will be executed 
     for the Directory Listings and 911 updates associated with these Orders; 
     CLEC will use the LI Office Gateways until EDI functionality is available, 
     tested and implemented.

3.4  INTERFACE CONTROL DOCUMENT

     3.4.1 The construction and execution of the interface implementation will 
     be fully documented by Pacific in an Interface Control Document. The 
     Interface Control Documents for the interfaces are listed in Section 2.2, 
     Scope.

     3.4.2 Interface Control Documents (ICD) identified in Section 2.2, Scope,
     serve to formalize the technical requirements and applicable business rules
     of functionality that the interface provides.

     3.4.3 Draft ICDs will be jointly reviewed and discussed. Once Pacific 
     issues the final ICD, Pacific will respond to written questions regarding 
     the ICDs. Any disputes regarding ICDs will be resolved pursuant to Section 
     4 hereof. Request for changes to the final ICD content will be handled via 
     the Change Control Process.

     3.4.4 Once an ICD has been established and Pacific plans a modification or 
     new functionality for an Interface, the ICD will be revised and CLEC will 
     be notified as described above in Section 3.2. Any disputes regarding ICDs 
     will be resolved pursuant to Section 4 hereof. The modified ICD will be 
     accompanied by a summary of the changes and identified by the date of 
     issue.
       
<PAGE>   189
3.5     INTERFACE TESTING

        3.5.1 Pacific and CLEC will perform interface testing as mutually agreed
        in the Test Plan. The parties will conduct testing on a set of interface
        functions for no longer than the interval specified in the Joint Testing
        Plan, unless a longer interval is mutually agreed to by both parties.
        Should the parties not agree whether a successful test was obtained
        within the specified interval, any disputes will be resolved pursuant to
        Section 4 hereof.

3.6     CHANGE CONTROL PROCESS

        3.6.1 Changes to the interface that are subject to the OBF and TCIF
        guidelines will be handled through the OBF and TCIF processes. Finalized
        OBF and TCIF guidelines that require or provide opportunity to change
        the interface will be managed as described in this JIA and the Change
        Control Process flow detail in Section 3.6.6 below.

        3.6.2 For all other changes, Pacific and CLEC SPOCs will serve as the
        liaison to receive the request. These requests will be reviewed and
        responded to by all parties based upon the guidelines established in
        this JIA and the Change Control Process flow detail in Section 3.6.6
        below. Any disputes will be resolved pursuant to Section 4 hereof.

        3.6.3 At such time that a written change is determined to be
        incorporated into the interface implementation, the appropriate ICDs
        will be updated to reflect such change or the agreement will be
        documented in correspondence. No verbal agreements or discussions will
        be construed to be final until this step has been executed. Any disputes
        will be resolved pursuant to Section 4 hereof.

        3.6.4 Change documentation (e.g. revised system specifications, etc.)
        will not be incorporated into the JIA but will be governed by it.

        3.6.5 Section 3.7 identifies the types of changes that will be
        identified by Pacific and CLEC within this JIA and those changes will
        adhere to the Change Control Process flow detail described in Section
        3.6.6 below. This process will pertain to changes initiated by Pacific
        and changes requested by CLEC within the scope of the implementation of
        the interface. Work on the affected interface may proceed, but in no
        case will implementation occur before disputes are resolved pursuant to
        Section 4 hereof.

        3.6.6 in all instances CLEC will receive written notice in order to
        evaluate the issue and have the opportunity to discuss it with Pacific.
        Any disputes will be resolved pursuant to Section 4 hereof.
        Specifically, these actions will follow the Change Control Process flow
        detail described in Sections 3.6.6.1 and 3.6.6.2 below.

                3.6.6.1 Flow detail for changes required to be made by CLEC to
                meet conversion date:

                1.  As the EDI/LSR issue requirements are being determined at
                    OBF, they are reviewed by Pacific to determine Pacific's LSR

3.7  CHANGE TYPES

     3.7.1  Major Change - Substantial technical process, Business Rule 
            modification(s) or change(s) to the interfaces that are required 
            and which will significantly impact the data transactions and system
            coding. Major changes including new categories of functionality not 
            included within the original scope and functionality covered by 
            this JIA will be incorporated into a new release that will be 
            subjected to a new JIA.

     3.7.2  Minor Change - Minor technical process, Business Rule 
            modification(s) or change(s) to the interfaces that are required, 
            but are easily incorporated into data transactions and system 
            coding. Minor changes may trigger a revision to an existing JIA but 
            will not require a new release and its corresponding new JIA.

3.8  IMPLEMENTATION SCHEDULING

     3.8.1  Section 5, Implementation Schedule, will be included in the initial 
     JIA for the defined interface. If a subsequent JIA needs to be issued in 
     connection with making major changes as described above, Pacific will 
     coordinate with interface users and publish a new Implementation Schedule 
     as outlined in Section 5 of the new JIA. Any disputes will be resolved 
     pursuant to Section 4 hereof.

     3.8.2  When a minor change is to be implemented but does not necessitate a 
     revision to this JIA, notification of implementation timelines for the 
     particular change(s) will be provided in writing to CLEC. Any disputes 
     will be resolved pursuant to Section 4 hereof.
<PAGE>   193
4.   OSS DISPUTE RESOLUTION

4.1  NEGOTIATIONS AND ESCALATION

     When the parties are not in agreement on Pacific's proposed business 
     rules, test plan, implementation, timeline or other aspects of an OSS 
     interface covered by this JIA, the parties shall promptly commence the 
     escalation process provided for in Section 4 of Appendix C of Attachment 
     11 of the Interconnection Agreement. The parties shall act and negotiate 
     in good faith using their best efforts to reach an agreement on the 
     disputed interface that is consistent with the needs of the industry (while
     recognizing reasonable cost and technical constraints) and that recognizes 
     that the interface must be made available by Pacific on a 
     nondiscriminatory basis and at parity to all CLECs and cannot be designed 
     to advantage or disadvantage any particular CLEC.

4.2  MAJORITY VOTE

     If the process described in Section 4.1 above does not resolve a dispute,
     CLEC may, in its sole discretion, either accept Pacific's position on the
     dispute or elect to seek the vote of other Affected CLECs (as defined in
     Section 4.3.1) that Pacific's position on the dispute is not acceptable to
     such Affected CLECs. Unless the Majority Vote (as defined in Section 4.3.2)
     is in favor of the proposed disputed change, Pacific shall not proceed with
     the proposed disputed change. If Pacific fails to garner a Majority Vote in
     favor of its position, at Pacific's election, Pacific will commence
     negotiations with the Affected CLECs to develop a position that is
     supported by a Majority Vote. The ability to appeal to the CPUC Staff for
     resolution has not been agreed to by the parties and will be resolved via
     Alternate Dispute Resolution.

4.3  DEFINITIONS FOR SECTION 4

     4.3.1.    "Affected CLECs" shall mean all CLECs which are using a 
     particular Pacific OSS interface as to which a dispute exists where 
     resolution of the dispute will impact such Affected CLECs usage of such 
     interface, all CLECs which are testing or are in the process of 
     implementing such OSS interface and all CLECs which have indicated a 
     definite intent to test, implement or use such OSS interface within the 
     next three months. Pacific shall not be treated as an "Affected CLEC" for 
     this purpose and shall have no vote. CLECs that are affiliates of each 
     other shall be considered the same CLEC.

     4.3.2.    "Majority Vote" shall mean 50% or more of all written statements 
     submitted by at least a Quorum of Affected CLECs to Pacific and CLEC 
     indicating that the signing Affected CLECs either (1) object to or (2) 
     support Pacific's position. Where a number of Affected CLECs join together 
     in one written statement, the votes of each Affected CLEC joining in the 
     statement shall be counted as if each had filed an individual statement. 
     For purposes of this definition, "Quorum" shall constitute two-thirds of 
     the Affected CLECs. In the event of a tie, the change proposed shall be 
     implemented by Pacific. In the event that less than two-thirds of Affected
     CLECs vote, the proposed change will not have garnered a Majority Vote, the
     proposed change will not be implemented, and the dispute will be submitted
     to the CPUC staff for resolution.

                                  MAINTENANCE

1.      PACIFIC shall provide repair, maintenance, testing and surveillance for 
        all Local Services and unbundled Network Elements and Combinations in 
        accordance with the terms and conditions of the Attachment.

2.      PACIFIC and CLEC shall mutually agree on appropriate maintenance 
        standards for all Local Services and unbundled Network Elements and 
        Combinations ordered under this Agreement. Such maintenance standards 
        shall include, without limitation, standards for testing, network 
        management, call gapping, and notification of upgrades as they become 
        available. Such maintenance standards shall be set forth in Attachment 
        17 to this Agreement.

3.      Maintenance and Repair Functions

3.1     Initial Electronic Bonding Interface Functions

        PACIFIC will have in place by April 10, 1997 a real time electronic
        system-to-system interface ("EBI") consistent with ATIS industry
        standards, to enable CLEC to perform any necessary maintenance and
        repair functions, including the ability to enter a new trouble ticket
        into the PACIFIC maintenance system for an CLEC Customer; the ability to
        retrieve and track current status on all CLEC Customer repair tickets;
        the ability to schedule maintenance appointments by day and time on a
        real-time basis and the ability to verify that the trouble has been
        resolved by work completed on the Customer's premises to the Minimum
        Point of Entry (MPOE) (collectively "EBI Functions"). Prior to
        implementation of EBI, PACIFIC will offer CLEC the use, at CLEC's
        option, of two interim interfaces for the performance of EBI Functions:
        (i) an 800 number and (ii) access to the PBSM system. PACIFIC will
        structure these interim interfaces so that CLEC will be able to perform
        all EBI Functions on an interim basis using the 800 number and the
        majority of the EBI using PBSM.

3.2     Additional Maintenance Functions

        Prior to the development of ATIS standards for adding to EBI (a) the 
        ability to retrieve MLT results, (b) the ability to retrieve "Dispatch 
        In-Dispatch Out" codes, and (c) the ability to retrieve all applicable 
        time and material charges at the time of ticket closure (itemized by 
        customer for each repair incident to

      individual items such as materials, if any, and total charges)
      (collectively "Maintenance Functions"), PACIFIC and CLEC will mutually
      agree on a process to accomplish CLEC's request for the Maintenance
      Functions on an interim, pre-EBI basis, and the cost, if any, to provide
      the Maintenance Functions.

4.    EBI Implementation

4.1   Maintenance and repair information exchange relating to all Local
      Services, Network Elements and Combinations provided under this Agreement
      will be transmitted over the same interface according to the same content
      definition. CLEC and PACIFIC will, for the purpose of exchanging fault
      management information, establish an EBI, based upon ANSI standards
      T1.227-1995 and T1.228-1995, and Electronic Communication Implementation
      Committee (ECIC) Trouble Report Format Definition (TRFD) Number 1 as
      defined in ECIC document ECIC TRA/95-003, and all standards referenced
      within those documents. The parties agree to adopt for EBI the functions
      currently implemented for reporting access circuit troubles. These
      functions include Enter Trouble, Request Trouble Report Status, Add
      Trouble Information, Modify Trouble Report Attributes, Trouble Report
      Attribute Value Change Notification and Cancel Trouble Report, all of
      which are fully explained in clauses 6 and 9 of ANSI T1.228-1995.

4.2   CLEC and PACIFIC will exchange requests over a mutually agreeable X.25
      based network or, if both CLEC's and PACIFIC's platforms are capable, a
      mutually agreeable TCP/IP based network may be employed. CLEC and PACIFIC
      will translate maintenance requests or responses originating in their
      internal processes into the agreed upon attributes and elements. Both
      parties, agree to complete mutually consistent translations within two (2)
      months after the Effective Date of this Agreement and to proceed to
      systems readiness testing that will result in a fully operational
      interface for local service delivery within four (4) months after the
      Effective Date of this Agreement. Changes to Network Operations Forum
      (NOF), ECIC or T1M1 standards, to the extent local service maintenance and
      repair are affected, will be implemented based upon a mutually agreeable
      schedule, but in no case will the time for adoption, including testing of
      the changes introduced, extend more than one (1) year beyond the date of
      initial closure by the relevant ATIS committee or subcommittee.

5.    In the event a PACIFIC employee misses a scheduled repair appointment on
      behalf of CLEC, PACIFIC will notify CLEC within one (1) hour of the missed
      appointment, either by EBI or by telephone.

6.    PACIFIC technicians shall provide repair service to CLEC Customers that is
      equal in quality to that provided to PACIFIC customers. Trouble calls from


                                                                        12/12/96

     CLEC shall receive response time priority that is at least equal to that of
     PACIFIC customers and shall be handled on a "first come first served" basis
     regardless of whether the customer is an CLEC Customer or a PACIFIC
     customer. Prior to EBI, CLEC may ask PACIFIC to reprioritize an CLEC
     customer trouble report among CLEC's other customer trouble reports and
     PACIFIC will reprioritize CLEC's various customer reports as requested by
     CLEC, if possible.

7.   PACIFIC shall provide CLEC with the same scheduled and non-scheduled
     maintenance, including, without limitation, required and recommended
     maintenance intervals and procedures, for all Local Services, Network
     Elements and Combinations provided to CLEC under this Agreement that it
     currently provides for the maintenance of its own network. PACIFIC shall
     provide CLEC at least ten (10) business days advance notice of any
     scheduled maintenance activity which may impact CLEC Customers. Scheduled
     maintenance shall include, without limitation, such activities as switch
     software retrofits, power tests, major equipment replacements and cable
     rolls. Plans for scheduled maintenance shall include, at a minimum, the
     following information: location and type of facilities, specific work to be
     performed, date and time work is scheduled to commence, work schedule to be
     followed, date and time work is scheduled to be completed and estimated
     number of work-hours for completion.


8.   PACIFIC shall advise CLEC of non-scheduled maintenance, testing,
     monitoring, and surveillance activity to be performed by PACIFIC on any
     Network Element, including, without limitation, any hardware, equipment,
     software, or system providing service functionality which may potentially
     impact CLEC Customers. PACIFIC shall provide the maximum advance notice of
     such non-scheduled maintenance and testing activity possible, under the
     circumstances; provided, however, that PACIFIC shall provide emergency
     maintenance as promptly as possible to maintain or restore service and
     shall advise CLEC promptly of any such actions it takes.

9.   PACIFIC shall provide CLEC with a detailed description of any and all
     emergency restoration plans and disaster recovery plans, however
     denominated, which are in place during the term of this Agreement. Such
     plans shall include, at a minimum, the following: (i) procedures for prompt
     notification to CLEC of the existence, location, and source of any
     emergency network outage potentially affecting an CLEC Customer, via the
     EBI to be established pursuant to Sections 3 and 4; (ii) establishment of a
     single point of contact responsible for initiating and coordinating the
     restoration of all Local Services and Network Elements or Combinations;
     (iii) methods and procedures to provide CLEC with real-time access to
     information relating to the status of restoration efforts and problem
     resolution during the restoration process; (iv) methods and procedures for
     reprovisioning of all Local Services



                                                                        12/12/96

                                                                          Page 4

          and Network Elements or Combinations after initial restoration; (v)
          equal priority, as between CLEC Customers and PACIFIC customers, for
          restoration efforts, consistent with FCC Service Restoration
          guidelines, including, without limitation, deployment of repair
          personnel, and access to spare parts and components; and (vi) a
          mutually agreeable process for escalation of maintenance problems,
          including a complete, up-to-date list of responsible contacts, each
          available twenty-four (24) hours per day, seven (7) days per week.
          Said plans shall be modified and up-dated as needed. PACIFIC shall 
          notify CLEC, within one hour, of all Category I Equipment and/or 
          facility failures affecting CLEC customer service as itemized in 
          PACIFIC reference S.I. 131, as amended by PACIFIC from time to time. 
          A copy of the relevant portion of S.I. 131 in effect on the effective 
          date of this Agreement is attached to this Attachment as Appendix A.

10.       PACIFIC and CLEC shall establish mutually acceptable methods and 
          procedures for referring callers to the 800/800 number supplied by 
          the other Party for purposes of receiving misdirected calls from 
          customers requesting repair.

11.       PACIFIC's Interconnection Service Center (ISC) shall conform to the 
          performance and service quality standards set forth in Attachment 17 
          when providing repair and maintenance to CLEC and CLEC Customers 
          under this Agreement.

11.1.     If service is provided to CLEC Customers before EBI is established 
          between CLEC and the PACIFIC, CLEC will transmit its repair calls to 
          the PACIFIC ISC by telephone.

11.2.     ISC, and Electronic Bonding, once deployed, shall be on-line and 
          operational and the interim interfaces described in Section 3 
          preceding shall be operational twenty-four (24) hours per day, seven 
          (7) days per week.

11.3.     Progress reports and status of repair efforts shall be available to 
          CLEC through EBI. On an interim basis before implementation of EBI, 
          PACIFIC shall provide progress reports and status of repair efforts 
          to CLEC via an 800 number supplied by PACIFIC or via PBSM, at CLEC's 
          option.

11.4.     Within thirty (30) days after the execution of this Agreement, 
          PACIFIC shall provide CLEC with written escalation procedures to be 
          followed if, in CLEC's reasonable judgment, any individual trouble 
          ticket or tickets are not resolved in a timely manner. Resolution 
          shall be deemed untimely if delayed beyond PACIFIC's best practices 
          for resolution of troubles reported by PACIFIC's own customers. The 
          escalation procedures to be provided hereunder shall include names 
          and telephone numbers of PACIFIC management personnel who are 
          responsible for maintenance issues.

11.5.     In the event PACIFIC shall fail to conform to the performance 
          standards in Attachment 17, CLEC may request, and PACIFIC shall 
          perform an analysis of the reason behind PACIFIC's failure to 
          conform, and PACIFIC shall correct said cause as soon as reasonably
          practical, at its own expense.

11.6.     Maintenance charges for premises visits by PACIFIC technicians shall 
          be billed by CLEC to its Customer, and not by PACIFIC. All forms, 
          business cards or other materials furnished by PACIFIC technicians to 
          CLEC Customers will contain no brand. If the CLEC Customer is not at 
          home when the PACIFIC technician arrives, the PACIFIC technician 
          shall leave on the premises "not-at-home" cards that are unbranded 
          but include a contact number for CLEC. The PACIFIC technician will 
          not leave on the premises a PACIFIC-branded "not-at-home" card".

11.7.     Dispatching of PACIFIC technicians to CLEC Customer premises shall be 
          accomplished by PACIFIC pursuant to a request received from CLEC.

                CATEGORY I SWITCHING MACHINES

                * Any switch congestion that results in 40% or more dial tone
                  delay lasting 15 minutes or longer.

                * Complete loss of inward and/or outward call processing
                  capability from a central office lasting 5 minutes or longer.

                * Any service interruption resulting in 50 or more customer
                  reports.

                * A duplex connectivity failure to the SS7 network, e.g.
                  MSB7/LPP frame, link set, CNI, etc.

                * Loss of interoffice calling from more than 10 minutes.

                * An FYI report should be filed anytime a central office has
                  been on battery power (greater than)30 minutes, when it is 
                  not part of a routine test.

                * E911

                        * A central office isolated from the E911 network for 15

                A community isolation occurs when no incoming or outgoing toll
                service is available and the community is cut off from the
                outside world by rural geography. A central office failure
                within a metropolitan area is not considered a community
                isolation since the community can more easily reach phone
                service in the adjacent central office serving area.

                CATEGORY I MEDIA INTEREST

                Any interruption or outage that may cause public or news media

     This Attachment describes the requirements for PACIFIC to bill and record
     all charges CLEC incurs for purchasing Local Services for resale and for
     Network Elements and combinations, and describes the requirements for
     PACIFIC and CLEC to bill and record all charges incurred to provide Meet
     Point Billing and Mutual Compensation. In addition to the terms and
     conditions set forth in this Attachment 13, CLEC and PACIFIC will use
     their best efforts to complete and sign by November 30, 1996 a Pre-Bill
     Certification Operating Agreement, which, when executed by both parties,
     will become Appendix A to this Attachment 13. The performance measurements
     applicable to Connectivity Billing and Recording are set forth in
     Attachment 17.

2.   TRANSITION TO CABS

     PACIFIC shall use a phased approach to introduce billing through CABS for
     Local Services. Network Elements and Combinations provided to CLEC under
     this Agreement. PACIFIC agrees to complete the conversion of CABS billing
     for Local Services, Network Elements and Combinations provided under this
     Agreement in accordance with the schedule set forth in Appendix B to this
     Attachment 13.

2.1  Each Party agrees to deliver billing information in the CABS format
     mutually agreed to and implemented by the Parties. Each reference to CABS
     in this Attachment 13 shall be understood prior to the date of CABS
     conversion to refer to the applicable pre-CABS billing system. Each
     reference to CABS in this Attachment 13 shall be understood as of the date
     of CABS conversion to refer to CABS.

2.2  Notwithstanding any other provisions or language to the contrary in this
     Agreement, the Parties agree to cease delivering billing information in
     CABS format, and to instead utilize the CRIS format, for resold Local
     Services effective May 11, 1998. Until such time as CLEC has developed and
     tested a conversion of its resale billing platform for CABS to CRIS, CLEC
     agrees to accept a paper CRIS bill beginning May 11 for resold Local
     Services. The Parties agree that CLEC's acceptance of a paper CRIS bill
     shall constitute conversion from CABS to CRIS."

3.   BILLABLE INFORMATION AND CHARGES

3.1  PACIFIC currently uses FABS, CRIS and CABS to bill the Network Elements.
     Local Services and Combinations that CLEC plans to purchase. PACIFIC will

                                                                   Attachment 13
                                                                          Page 2



     convert billing for all Network Elements, Local Services and Combinations
     to a CABS billing format in accordance with the schedule set forth in
     Appendix B. References to CABS billing in this Attachment apply to billing
     for the specified service following conversion to CABS.

3.2  PACIFIC will bill and record in accordance with this Attachment those
     charges CLEC incurs as a result of CLEC purchasing from PACIFIC Network
     Elements, Combinations and Local Services, as set forth in this Agreement
     (hereinafter "Connectivity Charges"). The Parties agree that, except as
     expressly provided in this Attachment, CABS or predecessor billing systems
     will comply with OBF standards.

3.3  Each bill for Connectivity Charges (hereinafter "Connectivity Bill") shall
     be formatted in accordance with CABS, CRIS or FABS, as appropriate,
     pursuant to the CABS Conversion schedule set forth in Appendix B. Each
     Element, Combination, or Local Service, purchased by CLEC shall be assigned
     a separate and unique billing code in the form agreed to by the Parties and
     such code shall be provided to CLEC on each Connectivity Bill in which
     charges for such Elements, Combinations, or Local Services appear. Each
     such billing code shall enable CLEC to identify the Element(s), or
     Combinations and Options as described in Attachment 11 to this Agreement
     ordered by CLEC, or Local Services ordered or utilized by CLEC in which
     Connectivity Charges apply pursuant to this Agreement. Each Connectivity
     Bill shall set forth the quantity and description of each such Element,
     Combination, or Local Service provided and billed to CLEC. All Connectivity
     Charges billed to CLEC must indicate the state from which such charges were
     incurred.

3.4  PACIFIC shall provide CLEC monthly Connectivity Bills that include all
     Connectivity Charges incurred by and credits and/or adjustments due to CLEC
     for those Elements, Combination thereof, or Local Services ordered,
     established, utilized, discontinued or performed pursuant to this
     Agreement. Each Connectivity Bill provided by PACIFIC to CLEC shall
     include: (1) all non-usage sensitive charges incurred for the period
     beginning with the day after the current bill date and extending to, and
     including, the next bill date, (2) any known unbilled non-usage sensitive
     charges for prior periods, (3) unbilled usage sensitive charges for the
     period beginning with the last bill date and extending up to, but not
     including, the current bill date, (4) any known unbilled usage sensitive
     charges for prior periods, and (5) any known unbilled adjustments.

3.5  The Bill Date, as defined herein, must be present on each bill transmitted
     by PACIFIC to CLEC.

                                                                   Attachment 13
                                                                          Page 3

3.6      Subject to Sections 3.6.4 and 3.6.5, PACIFIC shall not provide any
         Connectivity Bills to CLEC having a Bill Date any later than the
         following dates:

3.6.1.   Sixty (60) days following the recording date for all resale usage and
         LSNE usage, except for calls requiring data exchange with third party
         carriers. e.g. intraLATA 0+ calls made within another state, which
         calls are subject to Section 3.6.2.

3.6.2    One hundred twenty (120) days following the recording date for calls
         requiring data exchange with third party carriers.

3.6.3    Sixty (60) days following the date the charges are incurred for all
         other Network Elements, Combinations, and all non-usage resale or LSNE
         charges.

3.6.4    The time limits set forth in Sections 3.6.1 and 3.6.2 are effective
         immediately. The time limit set forth in Section 3.6.3 will be
         effective six (6) months following the effective date of this
         Agreement.

3.6.5    If any billing error is identified, quantified and communicated in
         writing by PACIFIC to CLEC within the time periods set forth in Section
         3.6.3 above after Connectivity Charges are incurred, Pacific will have
         a maximum of one hundred twenty (120) days after the Connectivity
         Charges are incurred to render correct Connectivity Bills therefor.

3.6.6    Provided that CLEC continues to participate in the Pre-Bill
         Certification Procedures described in Appendix A to this Attachment, no
         payment shall be due from CLEC for any Connectivity bill received by
         CLEC from PACIFIC that fails to meet the timeliness requirements of
         Section 3.6.1 through 3.6.5 of this Attachment.

3.6.7    On each bill where "Jurisdiction" is identified, local and local toll
         charges shall be identified as "Local" and not as interstate,
         interstate/interLATA, intrastate, or intrastate/intraLATA.


3.7      PACIFIC shall bill CLEC for each Element, Combination thereof, or Local
         Service, supplied by PACIFIC to CLEC pursuant to this Agreement at the
         rates set forth in Attachment 8. PACIFIC will bill CLEC based on the
         actual Connectivity Charges incurred, provided, however, for those
         usage-based Connectivity Charges where actual charge information is not
         determinable by PACIFIC because the jurisdiction (i.e., interstate,
         interstate/interLATA, intrastate, intrastate/intraLATA, local) of the
         traffic is unidentifiable, the parties will jointly develop a process
         to determine the appropriate charges.

3.8      Each party shall be responsible for (1) all costs and expenses it
         incurs in complying with its obligations under this Attachment 13 and
         (2) the

<PAGE>   210
                                                                   Attachment 13
                                                                          Page 4

        development, modification, technical installation and maintenance of any
        systems or other infrastructure which it requires to comply with and to
        continue complying with its responsibilities and obligations under this
        Attachment 13, except that Pacific may recover the cost to implement the
        billing system changes required by this Attachment in a competitively
        neutral manner on an industry wide basis.

3.9     Each Party shall provide the other Party at no additional charge a
        contact person for the handling of any Connectivity Billing questions or
        problems that may arise during the implementation and performance of the
        terms and conditions of this Attachment.

4.      MEET POINT BILLING

4.1     CLEC and PACIFIC will establish meet-point billing ("MPB") arrangements
        for jointly provided switched access to an IEC, in accordance with the
        Meet Point Billing guidelines adopted by and contained in the OBF's
        MECAB and MECOD documents, except as modified herein. Both parties will
        use their best reasonable efforts, individually and collectively, to
        maintain provisions in their respective federal and state access
        tariffs, and provisions within the National Exchange Carrier Association
        ("NECA") Tariff No. 4, or any successor tariff to reflect the MPB
        arrangements identified in this Agreement, in MECAB and in MECOD.

4.2     CLEC and PACIFIC will implement the "Multiple Bill/Single Tariff" option
        in order to bill any interchange carrier ("IXC") for that portion of
        the network elements provided by CLEC or PACIFIC. For all traffic
        carried over the MPB arrangement, CLEC and PACIFIC shall each bill the
        IEC for its own portion of the applicable elements.

4.3     Each Party shall provide the billing name, billing address, and carrier
        identification code ("CIC") of the IXCs that may utilize any portion of
        CLEC's network in an CLEC/PACIFIC MPB arrangement in order to comply
        with the MPB Notification process as outlined in the MECAB document.
        Each party will be entitled to reject a record that does not contain a
        CIC code. Such information shall be provided by each Party to the other
        Party in the format and via the medium that the parties agree.

4.4     The Parties agree to comply with the currently effective MECAB
        guidelines as mutually adopted by the Parties from time to time.

4.5     The Parties further agree that in those MPB situations where one Party
        subtends the other Party's access tandem, the Party providing the access
        tandem is only entitled to bill the access tandem fee and any associated
        local transport charges. The Parties also agree that the Party who
        provides the


 

<PAGE>   211
                                                                   Attachment 13
                                                                          Page 5

        end office switching is entitled to bill end office switching fees,
        local transport charges, RIC and CCL charges, as appropriate, and such
        other applicable charges.

4.6     PACIFIC and CLEC will record and transmit MPB information in accordance
        with the standards and in the format set forth in this Attachment.
        PACIFIC and CLEC will coordinate and exchange the billing account
        reference ("BAR") and billing account cross reference ("BACR") numbers
        for the MPB arrangements described in this Agreement. Each Party will
        notify the other if the level of billing or other BAR/BACR elements
        change, resulting in a new BAR/BACR number.

4.7     The secondary billing company will provide to the initial billing 
        company any necessary AMA records (in standard EMR format) within
        fourteen (14) days of the recording date. The Initial billing company
        will provide the secondary billing company the necessary summary records
        with fourteen (14) days of the initial company's bill date.

4.8     If MPB data is not submitted by either Party within the period set forth
        in 4.7, or is not in the proper format as set forth in this Agreement,
        and if as a result the other Party is delayed in billing the IXC for the
        appropriate charges it incurs, the delaying Party shall pay the other
        Party a late MPB data delivery charge which will be the total amount of
        the delayed charges times the highest interest rate (in decimal value)
        which may be levied by law for commercial transactions, compounded daily
        for the number of days from the date the MPB charge information is
        actually received.

4.9     Failure of secondary billing company to provide the necessary AMA
        records (in standard EMR format) within sixty (60) days of the recording
        date or of the initial billing company to provide the necessary summary
        records within sixty (60) days of the initial billing company's bill
        date, will result in the Party failing to deliver the data to be liable
        to the other Party for any charges the other Party is unable to bill the
        IEC.

4.10    Errors in MPB data exchanged by the Parties may be discovered by CLEC,
        PACIFIC or the billable IXC. Both CLEC and PACIFIC agree to provide the
        other Party with notification of any discovered errors within ten (10)
        business days of the discovery. The other Party shall correct the error
        within twenty (20) business days of notification and resubmit the data.
        In the event the errors cannot be corrected within the time period
        specified above, the erroneous data shall be considered lost. If either
        Party fails to provide MPB data due to loss, uncorrectable errors or
        otherwise, the Parties shall follow the procedures set forth in
        Attachment 14, Section 6, for compensation of lost,
<PAGE>   212
                                                                   Attachment 13
                                                                          Page 6


          damaged or destroyed Recorded Usage data and compensate the other for 
          the lost MPB billing data.

4.11      Both Parties will provide the other a single point of contact to 
          handle any MPB questions.

5.        COLLOCATION

          When CLEC collocates with PACIFIC in LEC's facility as described in
          this Agreement, capital expenditures (e.g., costs associated with
          building the "cage"), shall not be included in the Connectivity Bill
          provided to CLEC pursuant to this Attachment. All such capital
          expenses shall be billed through FABS, identified as capital expense
          charges and given a unique and consistent Billing Account Number. All
          invoices for capital expenses shall be sent to the location specified
          by CLEC for payment. All other non-capital recurring collocation
          expenses shall be billed to CLEC in accordance with this Agreement.
          The CABS Billing Output Specifications ("BOS") documents provide the
          guidelines on how to bill the Connectivity Charges associated with
          collocation. The bill label for those collocation charges shall be
          entitled "Expanded Interconnection Service."

6.        MUTUAL COMPENSATION

6.1       The Parties shall bill each other call termination charges for local
          exchange traffic, using a CABS like format, in accordance with the
          standards set forth in this Agreement for traffic terminated to the
          other Party's customer, where both such customers bear NPA-NXX
          designations associated with the same LATA or other authorized area
          (e.g., extended area service zones in adjacent local calling areas).
          Where required, such traffic shall be recorded and transmitted to CLEC
          in accordance with this Attachment. Further, the traffic exchanged
          pursuant to this Attachment shall be measured in billing minutes of
          use and shall be in actual conversation seconds. The total
          conversation seconds per chargeable traffic type will be totalled for
          the entire monthly billing cycle and then rounded to the next whole
          conversation minute. Reciprocal compensation for the termination of
          this traffic shall be charged at rates specified in Attachment 18 to
          this Agreement.

7.        ISSUANCE OF CONNECTIVITY BILLS - GENERAL

7.1       PACIFIC and CLEC will issue all CABS Connectivity Bills in accordance 
          with the terms and conditions set forth in this Section.

7.2       PACIFIC and CLEC will establish monthly billing dates ("Bill Date") 
          for each Billing Account Number ("BAN") or Billed Telephone Number 
          ("BTN") (collectively referred to as "Account Number"), as further 
          defined in the
<PAGE>   213
                                                                   Attachment 13
                                                                          Page 7


          CABS documents, which Bill Date shall be the same day month to month. 
          Each Account Number shall remain constant from month to month, unless 
          changed as agreed to by the Parties. Each Party shall provide the 
          other Party at least thirty (30) calendar days written notice prior 
          to changing, adding or deleting an Account Number. The Parties will 
          provide one Connectivity Billing invoice associated with each Account 
          Number.

7.3       All Connectivity Bills must be received by the other Party no later 
          than ten (10) calendar days from Bill Date and at least twenty (20) 
          calendar days prior to the payment due date (as described in this 
          Attachment), whichever is earlier. Any Connectivity Bill received on 
          a Saturday, Sunday or a day designated as a holiday by the Chase 
          Manhattan Bank of New York (or such other bank as CLEC shall specify) 
          will be deemed received the next business day. If either Party fails 
          to receive Connectivity Billing data and information within the time 
          period specified above, the payment due date will be extended by the 
          number of days the Connectivity Bill is late.

7.4       PACIFIC and CLEC shall issue all CABS Connectivity Bills containing 
          such billing data and information in accordance with CABS Version 
          26.0, or such later versions of CABS as are published by Bellcore, or 
          its successor and implemented by PACIFIC or CLEC, except that if the 
          parties enter into a meet-point billing arrangement, such 
          Connectivity Billing data and information shall also conform to the 
          standards set forth in the MECAB document, or such later versions as 
          are adopted by OBF, or its successor. To the extent that there are no 
          CABS or MECAB standards governing the formatting of certain data, 
          such data shall be issued in the format mutually agreed by the 
          Parties.

7.5       Each Party will provide the other Party written notice of which 
          Connectivity Bills are to be deemed the official bills to assist the 
          Parties in resolving any conflicts that may arise between the 
          official bills and other bills received via a different media which 
          purportedly contain the same charges as are on the official bill. If 
          either Party requests an additional copy(ies) of a bill, such Party 
          shall pay the other Party a reasonable fee per additional bill copy 
          as set forth in applicable tariffs or as mutually agreed, unless such 
          copy was requested due to errors, omissions, or corrections or the 
          failure of the transmission to comply with the specifications set 
          forth in this Agreement.

7.6       To avoid transmission failures or the receipt of Connectivity Billing 
          information that cannot be processed, the Parties shall provide each 
          other with their respective process specifications and edit 
          requirements. CLEC shall comply with PACIFIC's processing 
          specifications when CLEC transmits Connectivity Billing data to 
          PACIFIC. PACIFIC shall comply with CLEC's processing specifications 
          when PACIFIC transmits Connectivity Billing data to CLEC. CLEC and 
          PACIFIC shall provide each other reasonable notice if a Connectivity 
          Billing transmission is received that does not meet such Party's

<PAGE>   214
                                                                   Attachment 13
                                                                          Page 8

        specifications or that such Party cannot process. Such transmission
        shall be corrected and resubmitted to the other Party, at the
        resubmitting Party's sole expense, in a form that can be processed. The
        payment due date for such resubmitted transmissions will be twenty (20)
        days from the date that the transmission is received in a form that can
        be processed and that meets the specifications set forth in this
        Attachment.

8.      ELECTRONIC TRANSMISSIONS

8.1     PACIFIC and CLEC agree that each party will transmit CABS Connectivity
        Billing information and data in the CABS format electronically via
        Connect: Direct (formerly known as Network Data Mover) to the other
        Party at the location specified by such Party. The Parties agree that a
        T1.5 or 56kb circuit to Gateway for Connect: Direct is required. CLEC
        data centers will be responsible for originating the calls for data
        transmission via switched 56kb or T1.5 lines. If PACIFIC has an
        established Connect: Direct link with CLEC, that link can be used for
        data transmission if the location and applications are the same for the
        existing link. Otherwise, a new link for data transmission must be
        established. PACIFIC must provide CLEC/Alpharetta its Connect: Direct
        Node ID and corresponding VTAM APPL ID before the first transmission of
        data via Connect: Direct. CLEC's Connect: Direct Node ID is "NDMATTA4"
        and VTAM APPL ID is "NDMATTA4" and must be included in PACIFIC's
        Connect: Direct software. CLEC will supply to PACIFIC its RACF ID and
        password before the first transmission of data via Connect: Direct. Any
        changes to either party's Connect: Direct Node ID must be sent to the
        other party no later than twenty-one (21) calendar days before the
        changes take effect.

8.2     The CABS Connectivity Billing information and data will be sent using
        the current OBF format implemented by mutual agreement of both Parties.

9.      TAPE OR PAPER TRANSMISSIONS

9.1     In the event either Party does not have Connect: Direct capabilities
        upon the effective date of this Agreement, such Party agrees to
        establish Connect: Direct transmission capabilities with the other Party
        within the time period mutually agreed and at the establishing Party's
        expense. Until such time, the Parties will transmit billing information
        to each other via magnetic tape or paper (as agreed to by CLEC and
        PACIFIC). Connectivity billing information and data contained on
        magnetic tapes or paper for payment shall be sent to the Parties at the
        following locations. The Parties acknowledge that all tapes transmitted

<PAGE>   216
                                                                   Attachment 13
                                                                         Page 10


        (except a magnetron-tape device). The Parties agree that they will only 
        use those shipping containers that contain internal insulation to 
        prevent damage. Each Party will clearly mark on the outside of each
        shipping container its name, contact and return address. Each Party
        further agrees that it will not ship any Connectivity Billing tapes in
        tape canisters.

9.3     All billing data transmitted via tape must be provided on a cartridge 
        (cassette) tape and must be of high quality, conform to the parties'
        record and label standards, 9-track, odd parity, 6250 BPI, group coded
        recording mode and extended binary-coded decimal interchange code
        ("EBCDIC"). Each reel of tape must be 100% tested at 20% or better
        "clipping" level with full width certification and permanent error free
        at final inspection. CLEC reserves the right to destroy a tape that has
        been determined to have unrecoverable errors. CLEC also reserves the
        right to replace a tape with one of equal or better quality.

9.4     Billing data tapes shall have the following record and label standards.
        The dataset serial number on the first header record of an IBM standard
        tape label also shall have the following format.

                                CABS BOS
        Record Length           225 bytes (fixed length)
        Blocking Factor         84 records per block
        Block size              18,900 bytes per block
        Labels                  Standard IBM
                                Operating System

9.5     A single 6-digit serial number must appear on the external (flat)
        surface of the tape for visual identification. This number shall also
        appear in the "dataset serial number field" of the first header record
        of the IBM standard tape label. This serial number shall consist of the
        character "V" followed by the reporting location's four digit
        Originating Company Code and a numeric character chosen by the sending
        company. The external and internal label shall be the same. The dataset
        name shall appear on the flat side of the reel and also in the "data set
        name field" on the first header record of the IBM standard tape label.
        PACIFIC's name, address, and contact shall appear on the flat side of
        the cartridge or reel.

10.     TESTING REQUIREMENTS

10.1    At least thirty (30) days prior to any billing system change there will 
        be a thirty day test period to ensure that bills can be processed by the
        Parties.

10.2    For CLEC, PACIFIC will send CLEC a mechanized CABS Connectivity Bill 
        for the first time via electronic transmission, or tape, or at least
        thirty (30) days prior to changing mechanized formats (i.e., from CRIS
        to CABS), PACIFIC shall send to CLEC Connectivity Bill data in the
        appropriate mechanized format for testing to ensure that the bills can
        be processed and that the bills comply with the requirements of this
        Attachment. PACIFIC shall also provide to CLEC's Company Manager,
        located at 500 North Point Parkway, FLOC B1104B, Alpharetta, Georgia
        30302, the PACIFIC's originating or state level company code so that it
        may be added to CLEC's internal tables at least thirty (30) calendar
        days prior to testing or a change in the PACIFIC's originating or state
        level company code. CLEC will notify PACIFIC within the time period
        agreed to by the parties if Connectivity Billing transmission fails to
        meet CLEC's testing specifications. PACIFIC shall make the necessary
        corrections within the time period agreed to with CLEC to ensure that
        billing transmissions meet CLEC's testing specifications. PACIFIC shall
        not send CLEC a mechanized Connectivity Bill (except for testing) until
        such bills meet CLEC's testing specifications. If PACIFIC meets CLEC's
        testing specifications, PACIFIC may begin sending CLEC mechanized
        Connectivity Bills on the next Bill Date, or within ten (10) days,
        whichever is later.

10.3    During the testing period, PACIFIC shall transmit to CLEC Connectivity 
        Billing data and information via paper transmission. Test tapes shall be
        sent to CLEC at the following location:

        ------------------------------------------------
        Test Tapes:     CRL Network Services

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

11.     BILL ACCURACY CERTIFICATION

        The Parties agree that in order to ensure the proper performance and 
        integrity of the entire Connectivity Billing process, the sending Party
        is responsible and accountable for transmitting to the receiving Party
        an accurate and current bill. PACIFIC agrees to implement control
        mechanisms and procedures to render a bill that accurately reflects the
        Network Elements, Combination and Local Services ordered and used by
        CLEC. These processes and methodology will be set forth in a Pre-Bill
        Certification Operating Agreement and will be attached to this
        Attachment 13 as Appendix B.

12.  ADDITIONAL REQUIREMENTS

     PACIFIC agrees that if it transmits data to CLEC in a mechanized format, 
     PACIFIC will also comply with the following specifications which are not 
     contained in CABS guidelines but which are necessary for CLEC to process 
     Connectivity Billing information and data:
          o The BAN shall not contain embedded spaces or low values.
          o The Bill Date shall not contain spaces or non-numeric values.
          o Each Connectivity Bill must contain at least one detail record.
          o Any "From" Date should be less than the associated "Thru" Date and 
            neither date can contain spaces.
          o The Invoice Number must not have embedded spaces or low values.

13.  PAYMENT OF CHARGES

13.1 Subject to the terms of this Agreement and except for bills rendered by 
     PACIFIC in the CRIS format, CLEC and PACIFIC will pay each other within 
     thirty (30) calendar days from the Bill Date, or twenty (20) calendar days 
     from the receipt of the bill, whichever is later. For bills rendered by 
     PACIFIC in the CRIS format, CLEC will pay PACIFIC within sixty (60) 
     calendar days from the Bill Date, or fifty (50) calendar days from the 
     receipt of the bill, whichever is later. If the payment due date is a 
     Sunday or is a Monday that has been designated a bank holiday by the Chase 
     Manhattan Bank of New York (or such other bank as CLEC specifies), payment 
     will be made the next business day. If the payment due date is a Saturday
     or is on a Tuesday, Wednesday, Thursday or Friday that has been designated
     a bank holiday by the bank as CLEC specifies), payment will be made on the 
     preceding business day.

13.2 Payments shall be made is U.S. Dollars via electronic funds transfer 
     ("EFT") to the other Party's bank account. At least thirty (30) days prior 
     to the first transmission of Connectivity Billing data and information for 
     payment, PACIFIC and CLEC shall provide each other the name and address of 
     its bank, its account and routing number and to who Connectivity Billing 
     payments should be made payable. If such banking information changes, 
     each Party shall provide the other Party at least sixty (60) days written 
     notice of the change and such notice shall include the new banking 
     information. The Parties will render payment via EFT. CLEC will provide 
     PACIFIC with one address to which such payments shall be rendered and 
     PACIFIC will provide to CLEC with only one address to which such payments 
     shall be rendered. In the event CLEC receives multiple Connectivity Bills 
     from PACIFIC which are payable on the same date, CLEC may remit one 
     payment for the sum of all Connectivity Bills payable to PACIFIC's bank 
     account specified in this subsection. Each Party shall provide the other 
     Party with a contact person for the handling of Connectivity Billing 
     payment questions or problems.

                                                                         Page 13

14.       BILLING DISPUTES

14.1      Each Party agrees to notify the other Party upon the discovery of a 
          billing dispute. In the event of a billing dispute, the Parties will 
          endeavor to resolve the dispute within sixty (60) calendar days of 
          the Bill Date on which such disputed charges appear. Resolution of 
          the dispute is expected to occur at the first level of management 
          resulting in a recommendation for settlement of the dispute and 
          closure of a specific billing period. Bill closure procedures agreed 
          to by the Parties will be set forth in the Pre-bill Certification 
          Operating Agreement, to be attached to this Attachment as Exhibit A. 
          Closure of a specific billing period will occur by joint agreement of 
          the Parties whereby the Parties agree that such billing period is 
          closed to any further analysis and financial transactions, except 
          those resulting from an Audit as described in Section 10 of the 
          General Section of this Agreement. Closure will take place within 
          three (3) months of the close of the applicable billing period. The 
          month being closed represents those Connectivity Charges that were 
          billed or should have been billed by the respective Bill Date. If the 
          issues are not resolved within the allotted time frame, the following 
          resolution procedure will begin:

14.1.1    If the dispute is not resolved within sixty (60) days of the Bill 
          Date, the dispute will be escalated to the second level of management 
          for each of the respective Parties for resolution.

14.1.2    If the dispute is not resolved within ninety (90) days of the Bill 
          Date, the dispute will be escalated to the third level of management 
          for each of the respective Parties for resolution.

14.1.3    If the dispute is not resolved within one hundred and twenty (120) 
          days of the Bill Date, the dispute will be escalated to the fourth 
          level of management for each of the respective Parties for resolution.

14.1.4    If the dispute is not resolved within one hundred and twenty (150) 
          days of the Bill Date, the dispute will be resolved in accordance 
          with the alternative dispute resolution procedures set forth in 
          Attachment 3.

14.1.5    If a Party disputes a Connectivity Charge and does not pay such 
          charge by the payment due date, such charges shall be subject to late 
          payment charges as set forth in the Late Payment Charges provision of 
          this Attachment. If a Party disputes Connectivity Charges and the 
          dispute is resolved in favor of such Party, the other Party shall 
          credit the Connectivity Bill of the disputing Party for the amount of 
          the disputed charges along with any late payment charges assessed no 
          later than the second Bill Date after the resolution of the dispute. 
          Accordingly, if a Party disputes Connectivity Charges and the dispute 
          is resolved in favor of the other Party, the disputing Party shall 
          pay the other Party the amount of the disputed charges and any 
          associated late payment charges assessed no later than the second 
          bill payment due date after the 
<PAGE>   220
                                                                   Attachment 13
                                                                         Page 14

        resolution of the dispute. In no event, however, shall any late payment
        charges be assessed on any previously assessed late payment charges.

15.     LATE PAYMENT CHARGES

        If either Party fails to remit payment for any Connectivity Charges
        described in this Attachment by the payment due date, or if a payment or
        any portion of a payment is received by either Party after the payment
        due date, or if a payment or any portion of a payment is received in
        funds which are not immediately available to the other Party, then a
        late payment penalty shall be assessed. The late payment charge shall be
        calculated based on the applicable tariffs of the billing Party, and the
        portion of the payment not received by the payment date times the
        highest interest rate (in decimal value) which may be levied by law for
        commercial transactions, compounded daily for the number of days from
        the payment date to and including the date that payment is actually
        made. In no event, however, shall interest be assessed on any previously
        assessed late payment charges.

16.     ADJUSTMENTS

16.1    Subject to the terms of this Attachment and Attachment 17, PACIFIC will
        debit or credit CLEC for incorrect Connectivity Billing charges;
        overcharges: Local Services Elements, or any Combination thereof,
        ordered or requested but not delivered; interrupted Local Services
        associated with any Element, or combination thereof; ordered or
        requested Local Services, Elements, or Combination thereof, of poor
        quality; and installation problems if caused by PACIFIC, adjustments
        will be administered per the applicable tariff or by mutual agreement.
        Such reimbursements shall be identified as an adjustment on the
        Connectivity Bill.

16.2    Subject to the terms of this Attachment, CLEC will debit or credit
        PACIFIC for incorrect charges; overcharges; under charges for mutual
        compensation as required or permitted by the applicable tariff or by
        mutual agreement. Such reimbursements shall be identified as such on the
        Bill.

17.     RECORDING OF CALL INFORMATION

17.1    The Parties agree to record call information in accordance with this
        subsection. These records shall be provided at a Party's request and
        shall be formatted pursuant to Bellcore standards if such standards
        exist, and otherwise as agreed by the Parties. These records shall be
        transmitted to the other Party daily in EMR format via Connect: Direct,
        provided however that if CLEC and PACIFIC do not have Connect: Direct
        capabilities, such records shall be transmitted as the Parties agree.
        PACIFIC and CLEC agree that they

      will retain, at each Party's sole expense, copies of all AMA records 
      transmitted to the other party for at least seven (7) calendar days after 
      transmission to the other Party.

17.2  Pacific shall provide to CLEC the Switched Access Detail Usage Data 
      (Category 11-00-xx records) via Connect:Direct on a daily basis within 
      fourteen (14) days of the last day of the billing period. The data will 
      be in a separate dataset from the usage records associated with the CLEC 
      Resale access lines. File name and attributes will be specified by CLEC.

17.3  CLEC shall provide to Pacific the Summary Usage Data (Category 11-50-xx 
      records) via Connect:Direct on a daily basis within fourteen (14) days of 
      the last day of the billing period. The data will be in a separate 
      dataset from the usage records associated with the CLEC Resale access

           forth in Appendix I to this Attachment, Section IV, paragraph 1.1.4.
           shall apply to any data of other carriers sent in error to CLEC.

3.4        Additional Provisions Regarding Call Detail

3.4.1      Local Service

3.4.1.1    PACIFIC represents and warrants that as of the effective date of this
           Agreement it does not record local usage for its own flat rate
           customers in the ordinary course of business. There are certain
           exceptions where special study or call detail analysis is performed,
           e.g., in cases where an incident of telephone harassment is under
           investigation. If PACIFIC begins recording local usage for its own
           flat rate customers in the ordinary course of business at a future
           date, PACIFIC will simultaneously begin such recording for CLEC
           resold flat rate customers, at no additional charge. If at a future
           date PACIFIC begins recording local usage for its own flat rate
           customers served by a particular switch, PACIFIC will simultaneously
           begin such recording for CLEC resold flat rate customers served by
           that switch, at no additional charge.

3.4.1.2    If CLEC asks PACIFIC to develop the capability to provide CLEC local
           usage data on resold flat local service, and PACIFIC does not record
           local usage for its own flat rate customers in the ordinary course of
           business, PACIFIC shall develop such

                                                                   Attachment 14
                                                                          Page 3


           capability consistent with Sec. 1.6 of Attachment 6. In such event,
           PACIFIC shall be entitled to track and recover applicable development
           costs as set forth in Attachment 8.

3.4.1.3    As of the effective date of this Agreement, in some PACIFIC switches,
           the terminating number for measured local calls may not be recorded
           during periods of high volume usage. For all such calls, PACIFIC will
           inform CLEC of the minutes of use. If and when the limitation
           described in this Section is removed, PACIFIC will provide to CLEC at
           no additional cost, the terminating number for all measured local
           calls, including calls made during periods of high volume usage.

3.4.2      LSNE

3.4.2.1    When CLEC purchases a LSNE from PACIFIC, that LSNE as provided by
           PACIFIC will include all the functions and capabilities of the switch
           and the software deployed at that time within the switch relating to
           recording of usage data, including the capability to record all local
           usage and the terminating number. The charge, if any, for the
           recording of usage data shall be included in the charge for the LSNE
           set forth in Attachment 8.

4.         RECORDED USAGE DATA FORMAT

4.1        PACIFIC will provide Recorded Usage Data in the EMR format and by
           category, group and record type, as specified in the CLEC Customer
           Usage Data Transfer Requirements, November 1996 ("Data
           Requirements"), which is attached hereto and incorporated herein as
           Appendix I.

4.2        PACIFIC shall include the Working Telephone Number (WTN) of the call
           originator on each EMR call record.

4.3        End user customer usage records and station level detail records
           shall be in packs in accordance with EMR standards.

4.4        PACIFIC shall append the recording point identification to each EMR
           call record the recording point identification or other mutually
           agreed upon code that specifically designates the recording switch.

5.         RECORDED USAGE DATA REPORTING REQUIREMENTS

5.1        PACIFIC shall segregate and organize the Recorded Usage Data in a
           format mutually agreed by the Parties.

5.2        PACIFIC shall provide segregated Recorded Usage Data to multiple CLEC
           biller locations as mutually agreed by the Parties.

                                                                          Page 4


5.3        PACIFIC, at no cost to CLEC, shall transmit to CLEC Recorded Usage
           Data in Bellcore EMR format, as modified by Appendix I to this
           Attachment, via CONNECT: Direct. If CLEC requests Recorded Usage Data
           in a format customized for CLEC, PACIFIC may charge CLEC pursuant to
           Attachment 8.

5.4        CLEC will test and certify the CONNECT: Direct interface to ensure
           the accurate receipt of Recorded Usage Data. PACIFIC shall make any
           changes necessary in the CONNECT: Direct interface to meet the
           requirements of this Attachment.

5.5        PACIFIC shall provide Recorded Usage Data to CLEC once a day Monday
           through Friday, excluding mutually designated holidays. PACIFIC shall
           provide to CLEC the Recorded Usage Data for a Local Service within
           the time period specified in Attachment 17 to this Agreement.

5.6        Each Party will establish a single point of contact to respond to
           CLEC call usage, data error, and record transmission inquiries from
           the other Party.

5.7        The Recorded Usage Data EMR format, content, and transmission process
           will be tested by CLEC for compliance with industry standards.

6.         RECORDING FAILURES

6.1        CLEC Recorded Usage Data determined to have been lost, damaged or
           destroyed as a result of an error or omission by PACIFIC in its
           performance of the recording function or due to an aberrant switch
           overload of limited duration and frequency, shall, upon CLEC's
           request, be recovered by PACIFIC at no charge to CLEC. In the event
           the data cannot be recovered by PACIFIC, PACIFIC shall estimate the
           messages and associated revenue, with assistance from CLEC, based
           upon the method described below. This method will be applied on a
           consistent basis, subject to modifications agreed to by PACIFIC and
           CLEC. This estimate will be used by the Parties to determine any
           amounts owed to CLEC. PACIFIC will provide this amount to CLEC via a
           check accompanied by a statement that clearly identifies the purpose
           of the check.

6.1.1      PARTIAL LOSS PACIFIC shall review its daily controls to determine if
           data has been lost. When there has been a partial loss, actual
           message and minute volumes shall be reported, if possible. Where
           actual data are not available, a full day shall be estimated for the
           recording entity, as outlined in Section 6.1.3 following. The amount
           of the partial loss is then determined by subtracting the data
           actually recorded for such day from the estimated total for such day.

6.1.2      COMPLETE LOSS Estimated message and minute volumes for each loss
           consisting of an entire AMA tape or entire data volume due to its
           loss prior to or during processing, loss after receipt, degaussed
           before processing, receipt of a blank or unreadable tape, or lost for
           other causes, shall be reported.

                                                                   Attachment 14
                                                                          Page 5



6.1.3      ESTIMATED VOLUMES From message and minute volume reports for the
           entity experiencing the loss, PACIFIC shall secure message/minute
           counts for the four (4) corresponding days of the weeks preceding
           that in which the loss occurred and compute an average of these
           volumes.

6.1.4      NET LOSS CALCULATION The amount due to CLEC will be calculated based
           on the Average Revenue Per Minute (ARPM) minus the average charge per
           minute (ACPM) that CLEC would have paid to PACIFIC, times the
           estimated lost minutes. The parties shall agree upon the appropriate
           ARPM and ACPM to apply.

EXCEPTIONS:

6.1.4.1    If the day of loss is not a holiday but one (1) (or more) of the
           preceding corresponding days is a holiday, use additional preceding
           weeks in order to procure volumes for two (2) non-holidays in the
           previous two (2) weeks that correspond to the day of the week that is
           the day of the loss.

6.1.4.2    If the loss occurs on a weekday that is a holiday (except Christmas),
           PACIFIC shall use volumes from the two (2) preceding Sundays.

6.1.4.3    If the loss occurs on Mother's Day, Christmas or the Monday after
           Thanksgiving, PACIFIC shall use volumes from that day in the
           preceding year.

6.2        CLEC may also request data be provided that has previously been
           successfully provided by PACIFIC to CLEC, provided the request is
           received within forty-five (45) days of original processing. PACIFIC
           reserves the right to bill CLEC for its direct costs of providing
           such data if CLEC makes such a request more than 45 days after
           original processing.

7.         CLEARINGHOUSE PROCEDURES

7.1        The Parties acknowledge that calls will be placed using the local
           service of one Party that will be billable to the customer for local
           service of another Party. In order to ensure that these calls are
           properly accounted for and billed to the appropriate customer, the
           parties have established clearinghouse procedures to accomplish these
           objectives in a separate agreement entitled Data Exchange Agreement
           for the Settlement of CATS messages and non CATS Messages. The
           Parties intend to use best efforts to sign that Agreement by November
           30, 1996.

7.1.1      CLEC shall identify a CMDS host for transmitting and receiving
           in-collect and out-collect local and intralata messages.

7.1.2      In the event CLEC fails to designate a CMDS host, PACIFIC agrees on
           an interim basis, if requested by CLEC, to serve as CLEC's CMDS host
           for out-collect billing subject to the rates, terms and conditions as
           mutually agreed by the Parties.

                                   SECTION II

                    RECORDED USAGE TO BE TRANSMITTED TO CLEC

1.         GENERAL

This section addresses the types of usage to be transmitted by PACIFIC to CLEC.

1.1        USAGE TO BE TRANSFERRED TO CLEC

1.1.1      CLEC USAGE TO BE TRANSFERRED

           The following messages recorded by PACIFIC are to be transmitted to
           CLEC. PACIFIC recorded usage is defined as:

           - intraLATA - Local

           - intraLATA-Toll

           NOTE: Rated incollect messages should be transmitted via the direct
           feed and can be intermingled with the unrated messages. No special
           packing is needed.

           PACIFIC is developing a direct return feed. CLEC may return via
           direct return feed, once developed, any of the above mentioned
           messages that cannot be rated and/or billed by CLEC, for reasons
           specified in the returns process. Returned messages will be sent to
           PACIFIC in EMR format. Standard EMR return codes will be utilized.

           File transfer specifications are included within Section III.

1.2        CLEC USAGE

           The Recorded Usage Data in a local resale environment includes all
           intraLATA toll and local usage. PACIFIC will provide CLEC with
           unrated EMR records associated with all intraLATA toll and local
           usage which PACIFIC records on CLEC's behalf.

           Any Category, Group and/or Record types approved in the future for
           PACIFIC will be included if they fall within the definition of this
           local resale phase. PACIFIC will give CLEC one hundred twenty (120)
           days advance notification of PACIFIC's intended implementation of
           additional Category, Group and/or Record types.

           NOTE: PACIFIC messages will be packed using the packing criteria
           outlined in Section VI. PACIFIC shall pack records for rated messages
           and non-rated messages in separate packages. Any request by CLEC for
           packing in a different arrangement (for example, using CLEC's RAO)
           shall be separately negotiated by the parties and shall be at a
           reasonable additional charge to CLEC.

                                   SECTION III

                       PACIFIC TO CLEC USAGE FEED GENERAL

1.         GENERAL

           This section contains the information required for PACIFIC to
           transmit the usage defined in Section II to CLEC. This section
           specifically addresses the dataset requirements and processing.

1.1        DETAILED EMR RECORD EDITS

           CLEC will perform detailed record edits on the unrated and rated
           messages upon receipt from PACIFIC. Messages that fail these edits
           may be returned to PACIFIC with mutually agreed upon return codes
           designated.

1.2        DUPLICATE RECORD CHECKS

           CLEC will perform record checks on the unrated and rated messages to
           validate that duplicate messages are not sent by PACIFIC to CLEC,
           except where valid duplicate messages are applicable, e.g., ISDN
           bonded . PACIFIC shall perform record checks to validate that
           duplicate messages are not sent to CLEC in accordance with CMDS
           standards.

1.3        PACIFIC TO CLEC USAGE FEED

1.3.1      USAGE DATA TRANSPORT REQUIREMENTS

           PACIFIC will provide the transport facility between the PACIFIC
           location and the CLEC location. It is CLEC's intent that usage data
           be transmitted via CONNECT:Direct whenever possible. In the event
           usage transfer cannot be accommodated by CONNECT:Direct because of
           extended (one business day or longer) facility outages, or if
           facilities do not exist, PACIFIC will contract for a courier service
           to transport the data via tape.

           PACIFIC will provide CLEC with contacts, Remote Identifiers (IDs),
           and expected usage data volumes for each sending location.

           CLEC will provide contacts responsible for:

           Receiving usage transmitted by PACIFIC.

           Receiving usage tapes from a courier service in the event of a
           facility outage.

1.3.2      PHYSICAL CHARACTERISTICS

                                                                   Attachment 14
                                                                      Appendix I
                                                                          Page 9



           In the event the electronic system for data transmission
           malfunctions, by mutual agreement PACIFIC shall provide the data to
           CLEC on tape or cartridge by courier. Such data will have the
           physical characteristics indicated in Appendix A. CLEC's intent is
           for variable block format (2,476 bytes) with a LRECL of 2472.

1.3.3      DATA DELIVERY SCHEDULES

           Data will be delivered to CLEC by PACIFIC daily (Monday through
           Friday) or as negotiated. CLEC and/or PACIFIC Data Center holidays
           are excluded. PACIFIC and CLEC will exchange schedules of designated
           Data Center holidays.

1.3.4      RESENDING DATA

           CLEC will notify PACIFIC as promptly as possible upon discovery of
           resend requirements if a pack or entire dataset must be replaced due
           to pack rejection, damage in transit, dataset name failure, etc.

1.3.5      PACK REJECTION

           Critical edit failure on the Pack Header or Pack Trailer records will
           result in pack rejection (e.g., detail record count not equal to
           grand total included in the pack trailer). Notification of pack
           rejection will be made by CLEC within one business day of processing.
           Rejected packs will be retransmitted to CLEC by PACIFIC.

1.3.6      HELD PACKS AND MESSAGES

           CLEC and PACIFIC will track pack number to control input based upon
           invoice sequencing criteria. PACIFIC will be notified of sequence
           failures identified by CLEC and resend procedures are to be invoked.

1.3.7      DATA CONTENT REQUIREMENTS

           EMR is the format to be used for usage data provided to CLEC.

1.3.8      PACKING REQUIREMENTS

           A pack shall contain a minimum of one message record or a maximum of
           9,999 message records plus a pack header record and a pack trailer
           record. A file transmission contains a maximum of 99 packs. A dataset
           shall contain a minimum of one pack. PACIFIC will provide CLEC one
           dataset per sending location with the agreed upon OCN populated in
           the Header and Trailer records.

           Within the Header and Trailer records, the FROM RAO identifies the
           location that will be sending usage to CLEC. PACIFIC will populate
           the FROM RAO field with the

                                                                      Appendix I
                                                                         Page 10


           unique numeric value identifying the location that is sending the
           data to CLEC. Also, Pack Header and Trailer will have the OCN
           appropriately populated.

           The FROM RAO, OCN, and Remote Identifiers will be used by CLEC to
           control invoice sequencing and each will have its own invoice
           controls. The FROM RAO will also be used to determine where the
           message returns file, containing any misdirected and unguidable
           usage, will be sent.

           The file's Record Format (RECFM) will be Variable Block (VB) Size
           2,476 and the Logical Record Length (LRECL) will be 2,472 bytes.

           CLEC has no special sort requirements for the packs sent by PACIFIC.

1.3.9      DATASET NAMING CONVENTION

           PACIFIC will transmit the usage to CLEC using the following dataset
           naming conventions. The dataset name (DSN) will be partitioned into
           five nodes, separated by periods as follows:

           NODE 1BB03PXNN*

           NODE 2.IBMUP

           NODE 3 (To be determined during negotiations)

           NODE 4.USAGE

           NODE 5.GNNNNVNN* (Generational Dataset to be incremented by sender).

           *The italicized "N" represents numeric fields determined during
           negotiations.

1.3.10     CONTROL REPORTS

           CLEC accepts input data provided by PACIFIC in EMR format in
           accordance with the requirements and specifications detailed in this
           section of the Attachment. In order to ensure the overall integrity
           of the usage being transmitted from PACIFIC to CLEC, data transfer
           control reports will be required. These reports shall be provided by
           CLEC to PACIFIC on a daily or otherwise negotiated basis and reflect
           the results of the processing for each pack transmitted by PACIFIC.

1.4        MESSAGE VALIDATION REPORTS

           CLEC will provide the following three daily (or otherwise negotiated)
           Message Validation reports to the designated PACIFIC System Control
           Coordinator. These reports will be provided for all data received
           within PACIFIC Local Resale Feed and will

           be transmitted Monday through Friday whether or not there have been
           any files transmitted.

1.4.1      MESSAGE VALIDATION PACK REJECT REPORT (A7287)

           This report provides information on packs rejected by CLEC. It lists
           the header and trailer record of each rejected pack and indicates the
           error codes and the associated error message which explains why the
           pack was rejected.

           An example of the report and a list of Valid Error Codes and
           associated error messages are provided in Appendix B.

1.4.2      MESSAGE VALIDATION PACK ACCEPTED REPORT (A7288)

           This report provides vital statistics and control totals by Record
           ID, Type of Service, Message Counts and Record Counts, for all valid,
           rejected and dropped messages. The information is provided in the
           following report formats and control levels:

           1.        PACIFIC Total Messages

           2.        PACIFIC Total Records

           3.        RAO Total Messages

           4.        RAO Total Records

           5.        Pack Total (Record Counts and Message Counts)

           The first four report formats include percentages that indicate the
           relationship of the daily input volume by Record ID and Type of
           Record to the total input volume provided by an RAO and PACIFIC.

           An example of the report is provided in Appendix C.

1.4.3      MESSAGE VALIDATION DETAIL ERROR REPORT (A7289)

           An EMR detailed error report is generated for each pack/ invoice that
           is received and processed by CLEC. The report lists, in vertical
           format, the complete 175 byte EMR record that has failed to pass the
           initial edit criteria. It prints this detailed information only for
           the first five EMR records that share a common error condition. The
           error condition is flagged on the report by one of two possible error
           codes preceding the field value. The error codes are:

                     (C)       DENOTES CRITICAL ERRORS

                     (I)       DENOTES INFORMATION ERRORS

           The last two pages of the report for a given pack/invoice provide the
           following control totals:

           Total Errors for each Field

           Total Records Received

           Total Records Dropped

           Total Records rejected to MIU

           Pack Reject Rate

           Total Default Count (represents the number of Files on all of the
           input records that had to be programmatically altered to meet the EMR
           standards and specifications.)

           If the entire pack/invoice has been rejected because of a Critical
           Error Rate greater than 0.5%, the last page of the report will
           display such a statement enclosed in asterisks.

           CLEC has provided PACIFIC a sample of this report.

1.4.4      CONTROL REPORTS - DISTRIBUTION

           Since PACIFIC is not receiving control reports, dataset names will be
established during detailed negotiations.

1.1.1      MESSAGE RATING

           CLEC will rate any individual messages (as defined in Section II),
           that have not already been rated by PACIFIC (information provider
           messages will be rated by PACIFIC), prior to transmitting the usage
           to a billing environment within CLEC.

1.1.2      APPLICATION OF TAXES/FEES/SURCHARGES

           CLEC will apply taxes, fees and surcharges as appropriate for the
           individual messages and/or customer accounts. The application of all
           taxes, fees and surcharges will be applied on all intralata local and
           toll usage received from PACIFIC.

1.1.3      DUPLICATE MESSAGES

           CLEC has existing duplicate checks as part of their message
           processing or billing functions. CLEC will perform these checks on
           the rated/unrated messages sent by PACIFIC duplicate message
           disposition procedures and reports will be identified by CLEC during
           negotiations.

1.1.4      RECORD EDITS

1.1.4.1    CLEC RECORD EDITS

           CLEC will perform detailed record edits on the rated and unrated
           messages prior to transmitting them to the billing environment. Rated
           & unrated records that do not pass CLEC edits will be returned to
           PACIFIC with thirty (30) days of the file date.

1.1.4.2    PACIFIC RECORD EDITS

           If PACIFIC has existing detailed record edits for rated and unrated
           messages, PACIFIC is to perform these edits.

           Rated and unrated records that do not pass CLEC edits will be
           returned to PACIFIC. PACIFIC will attempt to perform error correction
           on all records requiring such action as agreed upon through the
           detailed negotiations process.

1.1.5      CLEC TO PACIFIC MESSAGE RETURNS

           At the discretion of CLEC, messages that have been sent to CLEC by
           PACIFIC that cannot be guided to an CLEC billed account or error in
           processing due to an error by PACIFIC will be returned to PACIFIC
           with the appropriate negotiated return codes.

                                    SECTION V

                        TEST PLANS AND ACTIVITIES GENERAL

1.         GENERAL

           This section defines the PACIFIC and CLEC activities which are
           required prior to implementation. The tests and activities described
           are necessary to ensure a smooth, accurate and well-programmed
           conversion. Specific test dates will be identified through the
           negotiations process.

1.1        INTERFACE TESTING

           The purpose of this test is to ensure that the usage described in
           Section II can be sent by PACIFIC to CLEC and can be accepted and
           processed by CLEC. PACIFIC will provide a test file to CLEC's
           designated Regional Processing Center (RPC) in the format that will
           be used for live day-to-day processing. The file will contain one
           full day's production usage. The format of the file will conform to
           the requirements shown in Section III. CLEC will review the file and
           verify that it conforms to its data center requirements. CLEC will
           notify PACIFIC in writing whether the format is acceptable. CLEC will
           also provide PACIFIC with the agreed-upon control reports as part of
           this test.

1.2        OPERATIONAL TEST

           The purpose of this test is to ensure that volumes of usage in
           consecutive sequence can be extracted, distributed, and processed by
           PACIFIC and CLEC.

           PACIFIC is required to provide CLEC with PACIFIC recorded, unrated
           intraLATA local and toll usage (as defined in Section II) for a
           minimum of five (5) consecutive days. CLEC will provide PACIFIC with
           the message validation reports associated with test usage.

           CLEC will rate and process the unrated intraLATA toll and local
           usage. CLEC will process this data to test bills. CLEC may request
           that the test usage contain specific usage volumes and
           characteristics to ensure a complete test. Specific usage volumes and
           characteristics will be discussed during detailed negotiations.

1.3        TEST FILE TRANSPORT

           Test data should be transported via CONNECT:Direct whenever possible.
           In the event that courier service must be used to transport test
           media the physical tape characteristics to be used are described in
           Appendix A.

                                   SECTION VI

                           POST DEPLOYMENT ACTIVITIES

1.         GENERAL

           Requirements for ongoing maintenance of the usage feeds between CLEC
           and PACIFIC are described in this section. Included am minimal
           requirements for day to day control of the regularly scheduled
           transfer of PACIFIC unrated and rated usage data and procedures for
           introducing and verifying CLEC/PACIFIC System Changes.

1.1        CONTROL MAINTENANCE AND REVIEW

1.1.1      PERIODIC REVIEW

           Control procedures for all usage transferred between PACIFIC and CLEC
           will require periodic review. This review may be included as part of
           an annual audit of PACIFIC by CLEC or as part of the normal
           production interface management function. Breakdowns which impact the
           flow of usage between PACIFIC and CLEC must be identified and jointly
           resolved as they occur. The resolution may include changes to control
           procedures, as similar problems would be avoided in the future. Any
           changes to control procedures would need to be mutually agreed upon
           by CLEC and PACIFIC.

1.1.2      RETENTION OF RECORDS

           PACIFIC shall maintain a machine readable back-up copy of the message
           detail provided to CLEC for a minimum of forty-five (45) calendar
           days. CLEC will maintain the message detail received from PACIFIC for
           a minimum period of forty-five (45) calendar days. Designated CLEC
           personnel will provide these records to PACIFIC or its authorized
           agents upon written request. PACIFIC will also provide any data back
           to CLEC upon their written request.

1.2        PACIFIC SOFTWARE CHANGES

           When PACIFIC plans to introduce any software changes which impact the
           format or content structure of the usage data feed to CLEC,
           designated PACIFIC personnel shall notify CLEC of such changes within
           any time period specified by the FCC or CPUC for that purpose, and in
           any event will use reasonable best efforts to notify CLEC no less
           than one hundred twenty (120) calendar days before such changes are
           Implemented.

           PACIFIC will communicate the projected changes to the appropriate
           groups in CLEC so that potential impacts on CLEC processing can be
           determined.

           CLEC personnel will review the impact of the change or the entire
           control structure as described in Section 1.5, Post Conversion Test
           Plan. CLEC will negotiate any perceived

           problems with PACIFIC and will arrange to have the data tested
           utilizing the modified software.

           If it is necessary for PACIFIC to request changes in the schedule,
           content or format of usage data transmitted to CLEC, PACIFIC will
           notify CLEC.

1.3        REQUESTED CHANGES

           If it is necessary for either Party to request changes in the
           schedule, content, or format of the usage data transmitted from
           PACIFIC, the requesting Party will notify the other Party and the
           terms and conditions of the change shall be mutually agreed upon
           pursuant to the process set forth in Section 1.5.2. When the
           negotiated changes are to be implemented, CLEC and/or PACIFIC will
           arrange for testing of the modified data as described in Section 1.5,
           Post Conversion Test Plan.

1.4        CLEC SOFTWARE CHANGES

           When CLEC plans to introduce any software changes which may impact
           the format or content structure of the usage data transmitted from
           PACIFIC, CLEC will use reasonable best efforts to notify the
           designated PACIFIC personnel, no less than one hundred twenty (120)
           calendar days before such changes are implemented.

           The CLEC contact will communicate the projected changes to the
           appropriate groups in PACIFIC so that potential impacts on PACIFIC
           processing can be determined.

           CLEC will negotiate any perceived problems with PACIFIC and will
           arrange to have the data tested utilizing the modified software.

           Altering the one hundred twenty (120) day window for introducing
           software changes can be negotiated by both companies, dependent upon
           the scope and impact of the change.

1.5        POST-CONVERSION TEST PLAN

           The test plan described below is designed to encompass all types of
           changes to the usage data transferred by PACIFIC to CLEC and the
           methods of transmission for that data.

1.5.1      PACIFIC SYSTEM CHANGE DESCRIPTION

           For a PACIFIC system change that would be reasonably likely to impact
           CLEC, PACIFIC shall provide CLEC with an overall description of the
           change, stating the objective and a brief explanation of the reasons
           for the change.

           During the initial negotiations regarding the change, PACIFIC shall
           provide a list of the specific records and/or systems impacted by the
           change to designated CLEC personnel.



                                       17
<PAGE>   246
                                                                   Attachment 14
                                                                      Appendix I
                                                                         Page 18


           Finally, PACIFIC shall also provide CLEC a detailed description of
           the changes to be implemented. It shall include sufficient detail for
           designated CLEC personnel to analyze and estimate the effects of the
           changes and to design tests to verify the accuracy of the
           implementation.

1.5.2      CHANGE NEGOTIATIONS

           PACIFIC will notify CLEC in writing of all proposed change
           negotiations initiated by PACIFIC. In turn, CLEC will notify PACIFIC
           in writing of proposed change negotiations initiated by CLEC.

           After formal notification of planned changes, whether originated by
           PACIFIC or CLEC, negotiation meetings shall be scheduled between
           designated CLEC and PACIFIC personnel. The first meeting should
           produce the overall change description (if not previously furnished)
           and the list of records and/or systems affected.

           In subsequent meetings, the Parties shall jointly develop a detailed
           description of changes to be implemented and a detailed test
           procedure.

1.5.3      CONTROL CHANGE ANALYSIS

           Based on the detailed description of the changes and review thereof
           by the parties in negotiation meetings, designated CLEC personnel
           will:

1.5.3.1    Determine the impact of the changes on the overall structure.

1.5.3.2    Determine whether any single change has a potential control impact
           (i.e., High error rate on individual records that might result in
           pack rejection).

1.5.3.3    Determine whether any controls might be adversely affected.

1.5.3.4    Arrange for appropriate control structure changes to meet any of the
           above conditions.

1.5.4      VERIFICATION OF CHANGES

           Based on the detailed description of changes and review thereof in
           negotiation meetings, designated CLEC personnel will:

1.5.4.1    Determine the type of change(s) to be implemented.

1.5.4.2    Develop a comprehensive test plan.

1.5.4.3    Negotiate scheduling and transfer of modified data with PACIFIC.

1.5.4.4    Negotiate testing of modified data with the appropriate CLEC Regional

                            LOCAL NUMBER PORTABILITY
                              AND NUMBER ASSIGNMENT

1.       PROVISION OF LOCAL NUMBER PORTABILITY

1.1      Each Party shall provide, to the extent technically feasible, service
         provider local Number Portability, subject to the Act, regulations
         thereunder and relevant FCC and Commission decisions. Until permanent
         Number Portability ("PNP") is available, each party shall provide
         Interim Number Portability ("INP"), through RCF and LERG reassignment,
         as described herein, immediately upon notification that CLEC is
         commencing facilities-based local exchange service on CLEC-provided
         facilities. Each Party shall provide INP through Flex DID and/or Route
         Indexing, as described below, no later than one hundred eighty (180)
         days after the effective date of this agreement or immediately upon
         CLEC's notification that it is commencing facilities-based local
         exchange service on CLEC-provided facilities, which ever occurs later.
         Each Party will provide INP with minimum impairment of functionality,
         quality, reliability and convenience to the other Party's subscriber.
         Each Party will provide PNP as soon as it is technically feasible, in
         conformance with FCC rules and the Act.

2.       INTERIM NUMBER PORTABILITY (INP)

2.1      INP shall be provided by Remote Call Forwarding ("RCF"), Flexible
         Direct Inward Dialing ("Flex DID"), Route Indexing ("RI") or Local
         Exchange Routing Guide ("LERG") Reassignment as provided herein. The
         Party that operates the switch to which the number is ported
         ("Ported-to Party") shall specify on a per telephone number or customer
         type basis which method is to be employed, and the Party that operates
         the switch from which the number is ported ("Porting Party") shall
         provide such method to the extent technically feasible. Both Parties
         agree to release ported telephone line numbers which were ported using
         INP methods other than LERG Reassignment, back to the Porting Party
         assigned an NXX in the LERG when the ported telephone line number
         "becomes vacant" (i.e., when the ported number is no longer in service
         for the customer originally assigned the ported number), and any
         applicable referral/intercept period has expired.

2.2      REMOTE CALL FORWARDING (RCF)

2.2.1    When RCF, which PACIFIC refers to as DNCF, is used to provide INP,
         calls to the ported number will first route to the Porting Party's
         switch. The Porting Party's switch will then forward the call to a
         second "shadow" number with an NXX associated with the Ported-to
         Party's switch. If necessary to handle multiple simultaneous calls to
         the same ported telephone number, the Ported-to Party may order up to
         ninety-nine (99) paths for the provisioning of RCF.

                                                                          Page 2

2.2.2    PACIFIC shall provide RCF INP to CLEC pursuant to the terms of
         PACIFIC's DNCF tariff (including any modification subsequently adopted
         by the Commission) filed by PACIFIC.

2.2.3    DNCF and CLEC's equivalent RCF INP service calls will be delivered over
         Local Interconnection Trunk Groups. Each Party's customers will have
         the ability to receive collect calls and bill to third party numbers.
         Call quality will be equivalent to that which other RCF customers
         receive.

2.3      FLEX DID

2.3.1    When Flex DID is used to provide INP, calls to the ported number will
         first route to the Porting Party's switch. The Porting Party's switch
         will then direct calls to the ported number over direct trunks to the
         Ported-to Party's switch. At the option of the Ported-to Party, and
         where technically feasible, Flex DID may be used to port either a block
         of telephone numbers or an individual telephone number, and Flex DID
         may be provisioned to allow a full ten (10) digit telephone number to
         be sent to the Ported-to Party's switch.

2.3.2    Flex DID will be delivered over dedicated truck groups using either MF
         or SS7 signaling, where technically feasible, at the option of the
         Ported-to Party.

2.4      ROUTE INDEXING

2.4.1    Route Indexing (RI) may take two forms: Route Indexing Portability Hub
         (RIPH) or Directory Number Route Index (DN-RI).

2.4.2    DN-RI is a form of RI that requires direct trunking between the Porting
         Party's switch to which the ported number was originally assigned and
         the Ported-to Party's switch to which the number has been ported. The
         Porting Party's switch shall send the originally dialed number to the
         Ported-to Party's switch without the use of steering digits.

2.4.3    RI-PH will be delivered over Local Interconnection Trunk Groups. DN-RI
         will be delivered over dedicated trunks using SS7 signaling

2.4.4    If the tandem switch is not operated by the Porting Party, the Porting
         Party will make whatever process and compensation arrangements with the
         tandem provider that are necessary to implement the steering digits for
         RI-PH.

2.5      LERG REASSIGNMENT

         If a customer has an entire NXX code and transfers from the Porting
         Party to the Ported-to Party, portability for that customer shall be
         provided by utilizing reassignment of the NXX code to the Ported-to
         Party through the Local Exchange Routing Guide (LERG). Updates to
         translations in the Porting Party's switching office to which the
         ported numbers were originally assigned will be made by the Porting
         Party prior to the date on 


<PAGE>   265
                                                                   Attachment 15
                                                                          Page 3

         which LERG changes become effective, in order to redirect calls to the
         Ported-to Party's switch via route indexing.

3.       OTHER INTERIM PORTABILITY PROVISIONS

3.1      With regard to the division of terminating Switched Access revenues
         associated with RCF, Flex DID and RI, the Porting Party shall pay the
         Ported-to Party $1.75 per month for each business line and $1.25 per
         month for each residence line associated with the INP arrangement.
         Determination of the number of lines to which the above payment shall
         apply will be made at the time the INP arrangement is established. The
         payment shall be made based on the total number of lines included in
         the same hunting arrangement as the INP number. Partial months will be
         paid on a prorated basis and such payment shall continue until the INP
         arrangement is disconnected or PNP is made available for the INP
         number, whichever occurs first. Such amount is in consideration of the
         Switched Access compensation and reciprocal compensation that would
         have been received by each Party if PNP had been in effect.

3.2      With RCF, Flex DID with SS7, DN-RI, or RI-PH, each Party shall exchange
         with the other Party, SS7 TCAP messages as required for the
         implementation of Custom Local Area Signaling Services (CLASS) or other
         features available in each Party's network.

3.3      Each Party shall disclose to the other Party any technical or capacity
         limitations that would prevent use of a requested INP implementation in
         a particular switching office. Both Parties shall cooperate in the
         process of porting numbers to minimize customer out-of-service time,
         including updating switch translations where necessary.

3.4      With respect to 911 service associated with ported numbers under INP,
         the Porting Party agrees that all ported directory numbers (DN) will
         remain in the Public Service Answering Points (PSAP) routing databases.
         When RCF INP or other INP methods that use a shadow number are used, it
         is the responsibility of the Ported-to Party to provide both the ported
         numbers and shadow numbers to the Porting Party to be stored in the
         Porting Party's appropriate databases. CLEC will input the ported
         number and the shadow number with CLEC's data via the E 911 Management
         System (MS) Gateway for storage in the MS. The Ported-to Party shall
         have the right to verify the accuracy of the information in the
         appropriate databases. CLEC may verify the accuracy of the information
         in the E 911 MS via the MS Gateway.

4.       PERMANENT NUMBER PORTABILITY (PNP)

4.1      The Parties agree to implement PNP, in compliance with FCC or CPUC
         orders, within and between their networks as soon as technically
         feasible, but no later than the schedule established by the FCC or
         CPUC.

4.2      Each Party shall recover its costs for PNP in accordance with FCC or
         CPUC orders.

                                                                          Page 3

4.3      The Parties agree to comply with such industry guidelines as may be
         established for the treatment of vacant telephone numbers, including
         provisions for number pooling, where available.

4.4      To the extent that a query is performed or required to be performed,
         each Party will make arrangements to perform its own queries for PNP
         calls.

5.       REQUIREMENTS FOR INP AND PNP

5.1      CUT-OVER PROCESS

         The Parties shall cooperate in the process of porting numbers from one
         carrier to another so as to limit service outage for the ported
         subscriber. This may include, but not be limited to, the Porting Party
         promptly updating its network element translations following
         notification by the industry SMS, or ported-to local service provider,
         and deploying such temporary translations as may be required to
         minimize service outage, e.g., unconditional triggers. The Parties
         agree to comply with such industry guidelines as may be established in
         the appropriate subcommittees of the California Local Number
         Portability Task Force for the cut-over process.

5.2      TESTING

         Both Parties shall cooperate in conducting testing to ensure
         interconnectivity between systems. Each Party shall inform the other
         Party of any system updates that may affect the other Party's network
         and each Party shall, at the other Party's request, perform tests to
         validate the operation of the network. Additional testing requirements
         may apply as specified by this Agreement.

5.3      NON-GEOGRAPHICAL NUMBERS

         Neither Party shall be required to provide Number Portability for
         nongeographic services (i.e., 500, 700 and 900 Service Access Codes
         (SACs), and 976 NXX and similar services) under this Agreement.

5.4      ENGINEERING AND MAINTENANCE

         Both Parties will cooperate to ensure that performance of trunking and
         signaling capacity is engineered and managed at levels which are at
         least at parity with that provided by the other Party to its
         subscribers and to ensure effective maintenance testing through
         activities such as routine testing practices, network trouble isolation
         processes and review of operational elements for translations, routing
         and network fault isolation. Additional specific engineering and
         maintenance requirements shall apply as specified in this Agreement.
         For subscribers ported by INP using RCF, Flex DID, or RI, the Ported-to
         Party shall perform appropriate testing to isolate trouble prior to
         referring repair requests to the Porting Party. For subscribers ported
         by PNP, trouble shooting by the Porting Party shall generally involve
         verification that a proper location routing number has been

                                                                   Attachment 15
                                                                          Page 5

         entered into the system, and other trouble shooting as may be
         established in industry guidelines.

5.5      RECORDING AND BILLING

5.5.1    The Porting Party shall provide the Ported-to Party with accurate
         billing and Customer Account Record Exchange data for the Ported-to
         Party's subscribers whose numbers have been ported.

5.5.2    Calls originated from RCF ported numbers in the Porting Party
         end-offices and sent to the Ported-to Party interLATA toll network must
         signal the shadow number in the Calling Party Number (CgPN) parameter
         and ported number in the Charge Number (CN) parameter in the SS7
         Initial Address Message.

5.6      Treatment of Telephone Line Number Based Calling Cards

5.6.1    PACIFIC shall remove from its Line Information Data Base (LIDB) all
         existing PACIFIC- issued Telephone Line Number (TLN)-based card numbers
         issued to a customer, when that customer ports the associated telephone
         numbers to CLEC

5.6.2    PACIFIC shall continue to allow CLEC access to its LIDB. Other LIDB
         provisions are specified in this Agreement.

6.       ASSIGNMENT OF NXX CODES AND TELEPHONE NUMBERS

6.1      The Parties agree, in principle, that the administration and assignment
         of Central Office Codes ("NXXs") should be moved from PACIFIC to a
         neutral third party. In the interim, where PACIFIC functions as
         California Code Administrator, the following provisions apply:

6.1.1    Each Party will comply with Industry Carriers Compatibility Forum
         ("ICCF") Central Office Code (NXX) Assignment Guidelines, INC
         95-0407-008 ("ICCF Guidelines").

6.1.2    Unless the FCC adopts rules that differ from the ICCF Central Office
         Code Assignment Guidelines, PACIFIC will assign NXX codes to CLEC
         according to those Guidelines in a competitively neutral manner and on
         a basis no less favorable than that on which PACIFIC assigns codes to
         itself. These Number Administrator functions will be provided without
         charge. Number Administrator functions do not include opening NXX
         Codes.

6.1.3    It shall be the responsibility of each Party to program and update its
         own switches and network systems to recognize and route traffic to the
         other Party's assigned NXX codes at all times. Neither PACIFIC nor CLEC
         shall charge each other for changes to switch routing software
         necessitated by the creation, assignment or reassignment or activation
         of NPA or NXX codes, so long as the requirement set forth at page 84 of
         Commission Decision 96-03-020 remains in place.


<PAGE>   268
                                                                   Attachment 15
                                                                          Page 6

6.1.4    The Parties will each be responsible for the electronic input of their
         respective number assignment information into the Routing Database
         System.

6.1.5    The Parties will provide to each other test-line numbers and access to
         test lines, including a test-line number that returns answer
         supervision in each NPA-NXX opened by a Party.

6.1.6    PACIFIC, in its role as the California Code Administrator, will provide
         routine reporting on NXX availability, consistent with the orders of
         the Commission.

6.1.7    The Parties agree that any forecasts required to be submitted prior to
         establishment of an independent third party administrator will be
         considered confidential and proprietary, and will only be made
         available to the California Code Administrator for the purposes of code
         assignment and administration.

6.2      In those circumstances where CLEC assigns its customers telephone
         numbers from an NXX assigned in the LERG to PACIFIC, CLEC shall be able
         to obtain and assign telephone numbers from PACIFIC in the same manner
         that PACIFIC performs these functions for its own customers.

6.2.1    CLEC can request, review, reserve, exchange and return telephone
         numbers for up to five basic exchange or COPT lines or single-line
         ISDN, on an electronic, real-time basis to allow assignment during
         service negotiation with the CLEC's customer. Such access shall be
         provided as described with respect to the Operational Support Services
         ("OSS") functions set forth in Attachment 11.

6.2.2    Number assignments other than those described in Section 6.2.1. above,
         including specialty numbers and complex product assignments, will be
         obtained through a telephone call to the unbranded Number Assignment
         Center (NAC) in the LISC. This NAC is unbranded to allow CLEC to
         include its customer in the call without indication that they are
         interacting with PACIFIC.

6.3      CLEC will be provided with electronic access for additional number
         products as soon as such access is made available by PACIFIC. Such
         access shall be provided as described with respect to other OSS
         functions set forth in Attachment 11.

         persons.

1.7.     With respect to any equipment, support equipment, systems, tools and
         data of one Party on the premises of the other Party, or spaces which
         contain or house the other Party's equipment or equipment enclosures,
         each Party shall comply with the security and safety procedures and
         requirements of the Party that owns or controls the premises, including
         but not limited to sign-in, identification and escort requirements.

1.8.     PACIFIC shall allow CLEC to inspect or observe spaces which house or
         contain CLEC equipment or equipment enclosures at any time within
         normal business hours and shall furnish CLEC with all keys, entry
         codes, lock combinations, or other materials or information which may
         be needed to gain entry into any secured CLEC space. In the

         access available to CLEC within three (3) hours after receiving a call
         from CLEC.

1.9.     PACIFIC agrees not to use card access readers and devices that use
         cards which are encoded identically, or that use mechanical coded locks
         on external doors or on internal doors to spaces which house mission
         critical equipment or equipment which supports the mission critical
         equipment.

1.10.    Keys used in PACIFIC's keying systems for spaces which contain or house
         CLEC equipment or equipment enclosures shall be limited to PACIFIC
         employees and representatives for emergency access only. CLEC shall
         have the right to require PACIFIC to change locks at PACIFIC's expense
         where there is evidence of inadequate security. In all other cases,
         CLEC may require PACIFIC to change locks at CLEC's expense.

1.11.    PACIFIC shall install security studs in the hinge plates of doors
         having exposed hinges if such doors lead to spaces which contain or
         house CLEC equipment or equipment enclosures.

1.12.    PACIFIC shall use reasonable measures to control' unauthorized access
         from passenger and freight elevators to spaces which contain or house
         CLEC equipment or equipment enclosures.

1.13.    PACIFIC shall provide notification within two (2) hours to designated

2.       ADDITIONAL PROVISIONS APPLICABLE TO COLLOCATION SPACES

2.1.     PACIFIC shall be responsible for the security of CLEC's collocation
         spaces. Security measures shall meet or exceed CLEC '5 requirements. If
         a security issue arises or if CLEC believes that PACIFIC's security
         measures fail to meet CLEC's requirements, CLEC shall notify PACIFIC
         and the Parties shall work together to address the problem. PACIFIC
         shall, at a minimum, do the following:

2.2.     PACIFIC shall design collocation cages to prevent unauthorized access.

2.3.     PACIFIC shall establish procedures for controlling access to the
         collocation areas by employees, security guards and others. Those
         procedures shall limit access to the collocation equipment areas to
         PACIFIC's employees, agents or invitees having a business need to be in
         these areas. PACIFIC shall require all persons entering the collocation
         equipment areas to wear identification badges.

         location for compliance with security procedures.

3.       DISASTER RECOVERY

3.1.     PACIFIC shall maintain for CLEC the same level of disaster recovery
         capability to be used in the event of a system failure or emergency as
         PACIFIC provides for itself. PACIFIC will provide CLEC with a written
         summary of such capability within 30 days after the effective date of
         this Agreement, subject to the non-disclosure provisions of this
         Agreement.

4.       DATA PROTECTION

4.1.     Each Party shall install controls in any of its data bases to which the
         other Party has access:

4.1.1.   to deny access to data base users after a pre-determined period of
         inactivity; and

4.1.2.   to protect the other Party's proprietary information and the other
         Party's customer proprietary information.

4.2.     PACIFIC shall maintain controls over databases used by CLEC to protect
         both ongoing operational and update integrity, at parity with control

INTRODUCTION

I.      Pursuant to Section 12 of this Agreement, Section A of this Attachment
        17 sets forth the service standards, measurements, and performance
        applicable to Local Services, Network Elements or Combinations provided
        under this Agreement.

        Section B of this Attachment 17 sets forth liquidated damages to be paid
        in the event that specified failures of performance occur.

        As experience is acquired under this Agreement with the new business
        processes established, the Parties expect to learn which measurements
        set forth in Section A are more or less useful than others. The Parties
        also expect that experience will show whether new measurements are
        needed or whether certain existing measurements are not needed.
        Accordingly, while this Agreement is in effect, either Party may, from
        time to time, request the addition, deletion or modification of the
        measures set forth in Section A. In the event the Parties cannot agree
        on such addition, deletion or modification they will submit such dispute
        for resolution to an Inter-Company Review Board, as identified in
        Section 3.1 of Attachment 3 to this Agreement provided, however, that
        other provisions of Attachment 3 shall not apply.

        Unless otherwise stated, PACIFIC shall make monthly reports to CLEC for
        all performance measures. Should a dispute arise concerning the accuracy
        of any of PACIFIC's measurements, CLEC may audit them under procedures
        set out in Section 11.9 of the Umbrella Agreement.

II.     "Parity" Defined: PACIFIC shall provide services to CLEC that, for any
        relevant period of measurement, have substantially the same
        characteristics of timeliness and performance as PACIFIC provides at
        retail and, for such purpose, those services shall be deemed to have
        substantially the same characteristics for any population of thirty (30)
        or more observations if it has the same statistical distribution at the
        90% confidence interval. Service Parity is achieved when PACIFIC's
        service performance, as defined by the designated comparable measures,
        is within 1.65 standard deviations (90% confidence level) of the average
        retail performance for the equivalent retail product or service, subject
        to the definitions contained within this Attachment 17. The calculation
        of 1.65 standard deviations will be based on the most recent two full
        calendar quarters of actual performance and revised quarterly. As used
        in the preceding sentence, PACIFIC's "average retail performance for the
        equivalent retail product or service" shall be calculated using all
        available observations of PACIFIC performance, rather than any form of
        sampling. "PACIFIC's service performance" for CLEC shall, similarly, be
        calculated using all available observations. Average performance will be
        measured and reported monthly for each comparable measure. Liquidated
        damages will apply when performance is not al parity.

        Service Parity applies to the comparable measures only. Other agreed to
        performance measures will be based on specified service standards and
        liquidated damages will apply as defined in this Attachment 17.

8.      SERVICE ORDER DISCREPANCY

        Definition:
        Measures percent of Orders initiated by CLEC that result in a
        discrepancy. The discrepancy is a result of CLEC issuance. An order will
        be considered to be discrepant if at any time after receipt of the order
        PACIFIC has to either reject the order or request a supplement of the
        order from the CLEC as a result of incomplete or inaccurate information,
        as defined in PACIFIC's Resale Access Line Request Forms Instruction
        Guide (GUIDE), Version 4, dated April 8, 1996. If CLEC service orders
        conform to the Guide, rejects or requests to supplement such service
        orders will be excluded from this measurement and will not incur
        Liquidated Damages, as defined in Section B of this Attachment. CLEC and
        PACIFIC will mutually agree on revisions to the Guide that effect
        service order form or content. If they are unable to agree, they will
        take the dispute to the Inter-company review Board as set forth in the
        Section I of the Introduction to this Attachment.

        Method of Calculation:
        As a measurement of Performance Standards, this metric will comply with

GENERAL DESCRIPTION:
        PACIFIC will provide Local Usage Information detail in an accurate
        timely manner. The format and content is described in the Bellcore
        EXCHANGE MESSAGE RECORD (EMR) document in effect as of the Effective
        Date of this Agreement and the CLEC Local Resale Data Transfer
        Requirements.

        Because these processes are new, CLEC and PACIFIC agree to jointly
        review and revise these performance standards as Local Resale is fully
        implemented to ensure that: 

        -    the processes are stabilized and that agreed upon in-service 
             volumes are met. 
        -    comparative measures of parity with PACIFIC's retail processes are
             established, where appropriate
        -    the standards reflect elements required by CLEC to bill end users, 
        -    an accurate baseline using some historical data for resale is in 
             place.

1.      FILE TRANSFER

        Definition:
        PACIFIC will initiate and transmit files that are error free and without
        loss of signal.

        performance and value for this standard will be done after six months
        from Effective Date. No comparative measure applies

        Reporting Period:
        Monthly

2.      % TIMELINESS

        Definition:
        PACIFIC will mechanically transmit, via CONNECT: Direct, all available
        usage records to CLEC's Message Processing Center once a day, Monday
        through Friday, or as negotiated. CLEC and/or PACIFIC's Data Center
        Holidays are excluded. CLEC and PACIFIC will exchange schedules of
        designated holidays.

        By January 1, 1997, PACIFIC and CLEC will jointly audit, review, and
        agree on comparative measures of timeliness; i.e. a measure of parity
        between the methods used to provide usage data to PACIFIC's retail
        billing and the methods used to process CLEC's usage data to CLEC.
        In-service thresholds will be determined using accepted statistical
        algorithms.

        In the interim, a joint analysis of the timeliness based on cooperative
        test accounts will be conducted to ensure common definitions and scope
        and to create a baseline for comparison. The following are interim
        benchmarks for timeliness:

Sept. - Nov. 1996:     90% of all messages delivered within 5 days from when 
                       message recorded.
Dec. - Jan. 1997:      95% of all messages delivered within 5 days from when 
                       message recorded.
Jan. - June 1997:      99% of all messages delivered within 10 days from when 
                       message recorded;
                       100% of all messages delivered within 30 days from when
                       message recorded; or demonstrate parity of performance
                       with PACIFIC Retail Business standard, as defined by
                       benchmark audit and analysis.

Note: The audit and analysis of performance during the above time frames is
intended to validate the parity of performance standards. Therefore, the above
time frames and measurements are exempt from Performance Credits / Liquidated
Damages as specified in Section B of this Attachment.

June 1997:             Specified Performance Standard:
End of Agreement       95% of all messages delivered within 5 days from when 
                       message recorded.
Jan. - June 1997:      99% of all messages delivered within 10 days from when 
                       message recorded;
                       100% of all messages delivered within 30 days from when
                       message recorded;

                       or;

                       Parity of Performance:
                       The above Specified Performance Standard is subject to
                       change upon PACIFIC's ability to demonstrate Parity of
                       Performance with its Retail Business standard, as defined
                       by benchmark audit and analysis.

        Note: The above time frame and measurement is not exempt from
        Performance Credits / Liquidated Damages as specified in Section B of
        this Attachment.

        Reporting Period:
        Monthly

3.      % RECORDED USAGE DATA COMPLETE (A SELF-REPORTING MEASUREMENT)

        Definition:
        PACIFIC will provide all required Recorded Usage Data and ensure that it
        is processed and transmitted within time periods established in
        Attachment 13.

        By January, 1997, in-service volume thresholds will be determined using
        accepted statistical algorithms to provide a basis for comparison with
        PACIFIC's retail performance. Because messages that are held in
        PACIFIC's error file are usually not uniquely identified, CLEC and
        PACIFIC agree to invoke auditing procedures, as defined in Section 11.1
        of the Agreement, to ensure that the rate of unbillable messages is in
        parity with the rate of unbillable messages experienced in PACIFIC's
        retail business.

        Method of Calculation:


              TOTAL NUMBER OF RECORDED USAGE DATA RECORDS DELIVERED
          DURING CURRENT MONTH MINUS NUMBER OF USAGE CALL RECORDS HELD
                          IN ERROR FILE AT END OF MONTH
          ------------------------------------------------------------
      TOTAL NUMBER OF RECORDED USAGE DATA RECORDS DELIVERED X 100 = 99.98%


4.      % ACCURACY

        Definition:
        PACIFIC will provide Recorded Usage Data in the format and with the
        content as defined in the Bellcore document. These measures relate only
        to Unbillable unrated local and local toll messages due to critical edit
        failures (format errors).

        Method of Calculation:


          TOTAL NUMBER OF UNRATED LOCAL MESSAGES TRANSMITTED CORRECTLY
          ------------------------------------------------------------
               TOTAL NUMBER OF UNRATED LOCAL MESSAGES TRANSMITTED      100=> 98%


        Note:  No comparative measure applies.

                          SECTION B LIQUIDATED DAMAGES

For certain delays or failures of either Party under this Agreement effective
July 1 1997 and there are at least thirty (30) occurrences per month per
Functional Activity, and on a Region Basis, as appropriate, the non-performing
Party shall pay the other Party the amounts calculated as provided below.

Average Non-Recurring Charges -
The Average Non-Recurring Charge is the sum of all non-recurring charges applied
to service orders issued by CLEC and for which there were performance defects (
e.g., Installation Appointment Missed, Late CSR, Service Order Discrepancy,
etc.) divided by the total number of defects within the measurement period.
These calculations will be made by Functional Activity and product
(Business-Single/Multi-line, Centrex, PBX Trunks), Residence, LINK, and ISDN.

Average Recurring Charges -
The Average Recurring Charge is the sum of all recurring charges applied to
service orders issued by CLEC and for which there were performance defects (
e.g. Maintenance Appointment Missed, Repeat Trouble, etc.) divided by the total
number of defects within the measurement period. These calculations will be made
by Functional Activity and product (Business-Single/Multi-line, Centrex, PBX
Trunks), Residence, LINK, and ISDN.

Below are listed selected functional activities which are critical to customer
satisfaction and the remedy payable by the non-performing Party for specific
lack of performance as described in the following table:

I.      LOCAL INTERCONNECTION TRUNK ARRANGEMENTS

        GENERAL

        The Parties will establish Local Interconnection Trunks to exchange
        local and intraLATA toll traffic. Neither Party shall terminate Switched
        Access traffic over Local Interconnection Trunks. Separate two-way Meet
        Point Trunks will be established for the joint provisioning of Switched
        Access traffic. Local Interconnection will be provided via two-way
        trunks unless both Parties agree to implement one-way trunks on a
        case-by-case basis.

        A.      Interconnection Within Each LATA.

                1.      Each Party will establish a Local Interconnection Trunk
                        Group with each Access Tandem in the LATA(s) in which it
                        originates or terminates local and/or toll traffic with
                        the other Party, unless CLEC orders LATA-Wide
                        Terminating Access from PACIFIC. The Parties may not
                        route Local Interconnection traffic to an Access Tandem
                        destined for an NXX that subtends another Tandem, except
                        as specified in Sections l.A.2 and II below. The Parties
                        agree that direct trunking to an end office from either
                        Party's end office or Access Tandem is permitted under
                        the terms of this section.

                2.      LATA-Wide Terminating Access

                        The Parties agree that CLEC may select a LATA-Wide
                        terminating arrangement. When CLEC selects such an
                        arrangement, interconnection is established at a single
                        tandem designated by PACIFIC for termination of all
                        Local Interconnection Traffic destined for any office in
                        that LATA.

                3.      Tandem-Level Terminating Access

                        Interconnection at PACIFIC tandems within each LATA:
                        CLEC will interconnect with all PACIFIC Access Tandems
                        in each of the LATA(s) in which it originates traffic
                        and interconnects with PACIFIC, unless CLEC selects the
                        LATA-Wide Terminating Option.

                4.      In addition to the tandem interconnection described
                        above, either Party may establish end office-to-end
                        office or end office-to-tandem or tandem-to-tandem trunk
                        groups. In the case of host-remote end offices, such
                        interconnection shall occur at the location of the host
                        or remote, at the option of the Party deploying the
                        host-remote end office.

                5.      CLEC and PACIFIC agree to interconnect their networks
                        through existing and/or new facilities between CLEC End
                        Offices and/or Access Tandem

                                       2

                        Switches and the corresponding PACIFIC End Office and/or
                        Access Tandems set forth in Appendix A. The Parties will
                        establish logical trunk groups referencing the
                        appropriate CLEC Routing Point and PACIFIC Central
                        Office. In addition, where necessary, and as mutually
                        agreed to, the Parties will define facilities between
                        their networks to permit trunk group(s) to be
                        established between the points listed in Appendix A.
                        While Appendix A is unpopulated at the time of execution
                        of this Agreement, CLEC shall initially populate
                        Appendix A; PACIFIC may populate Appendix A further,
                        under paragraph 6 below.

                6.      Nothing in the foregoing restricts either Party from
                        ordering and establishing CLEC and/or PACIFIC Local
                        Interconnection trunk groups in addition to the initial
                        combinations described above. Amendments to Appendix A
                        may be made by either Party, upon 30 days written notice
                        and acceptance by the other Party. Acceptance will not
                        be unreasonably withheld. Such amendments may be made
                        without the need to renegotiate the terms of the rest of
                        this Attachment.

        B.      Single P01 Model.

                1.      For each interconnection between the Parties for the
                        exchange of local, intraLATA toll, and meet-point
                        Switched Access traffic, the Parties agree that CLEC
                        will designate a single Point Of Interconnection between
                        any two switching entities.

        C.      Sizing and Structure of Interconnection Facilities.

                1.      The Parties will mutually agree on the appropriate
                        sizing for facilities based interconnection, based on
                        the standards set forth below. The capacity of
                        interconnection facilities provided by each Party will
                        be based on mutual forecasts and sound engineering
                        practice, as mutually agreed to by the Parties during
                        planning and forecasting meetings. The interconnection
                        facilities provided by each Party shall be formatted
                        using either Alternate Mark Inversion Line Code or
                        Superframe Format Framing. D53 facilities will be
                        optioned for C-bit Parity.

                2.      When interconnecting at PACIFIC's tandems, the Parties
                        agree to establish Bipolar 8 Zero Substitution Extended
                        Super Frame ("B8ZS ESF") two-way trunks where
                        technically feasible for the sole purpose of
                        transmitting 64k CCC data calls. In no case will these
                        trunks be used for calls for which the User Service
                        Information parameter (also referred to as "Bearer
                        Capability") is set for "speech" unless all available
                        non 64K CCC circuits are busy. If all such circuits are
                        busy, CLEC and PACIFIC agree to use Network Management
                        Controls (including inter alia, re-routing to 64K CCC
                        trunk groups) pursuant to Section XII of this Attachment
                        to relieve

<PAGE>   299

                                                                   Attachment 18

                        network congestion temporarily. Where additional
                        equipment is required, such equipment would be obtained,
                        engineered, and installed on the same basis and with the
                        same intervals as any similar growth job for IXC, CLC,
                        or PACIFIC internal customer demand for 64K CCC trunks.

                3.      When interconnecting at PACIFIC's digital End Offices,
                        the Parties have a preference for use of BBZS ESF
                        two-way trunks for all traffic between their networks.
                        Where available, such trunk equipment will be used for
                        these Local Interconnection Trunk Groups and Meet Point
                        Trunk Groups. Where AMI trunks are used, either Party
                        may request upgrade to B8ZS ESF when such equipment is
                        available.

        D.      Combination Interconnection Trunks.

                1.      The Parties agree to work cooperatively to combine all
                        functionalities of Local Interconnection Trunk Groups
                        and Meet Point Trunk Groups on a single Combination
                        Interconnection Trunk Group at any feasible Point Of
                        Interconnection where either Party desires, except in
                        connection with the LATA-Wide terminating option.

                2.      The Parties agree to make the initial decision as to
                        whether the use of Combination Interconnection Trunk
                        Groups is feasible, including a determination of
                        switched software compatibility, ordering procedures and
                        billing procedures, no later than six months from the
                        effective date of this Agreement.

                3.      If the Parties find the use of Combination
                        Interconnection Trunk Groups not to be feasible at that
                        time, the Parties will undertake a review of such
                        feasibility and a further decision on the use of
                        Combination Interconnection Trunk Groups at six month
                        intervals, at either Party's option, through the term of
                        the Agreement.

                4.      Until the Parties find Combination Interconnection Trunk
                        Groups to be feasible, Local Interconnection will be
                        provided via one-way and/or two-way trunks.

                5.      Whenever the use of Combination Interconnection Trunk
                        Groups is determined to be feasible, and ordering and
                        billing procedures have been established:

                        a)      Any new trunk groups may be ordered using the
                                Combination Interconnection Trunk Group option;
                                and

                        b)      The Parties will work together in good faith to
                                complete the conversion from the use of separate
                                Local Interconnection Trunk

                                                                   Attachment 18


                                Groups and Meet Point Trunk Groups to the use of
                                Combination Interconnection Trunk Groups within
                                six months from that time.

        E.      Signaling Protocol. The Parties will interconnect their networks
                using SS7 signaling as defined in GR-317 and GR-394, including
                ISDN User Part ("IS UP") for trunk signaling and Transaction
                Capabilities Application Part ("TCAP") for CCS-based features in
                the interconnection of their networks. Either Party may
                establish CCS interconnections either directly and/or through a
                third party. CCS interconnection, whether direct or by third
                party shall be pursuant to PUB L-780023-PB/NB and in accordance
                with the rates, terms and conditions of the Parties' respective
                tariffs. The Parties will cooperate in the exchange of TCAP
                messages to facilitate full interoperability of CCS-based
                features between their respective networks, including all CLASS
                features and functions, to the extent each carrier offers such
                features and functions to its own end users. The Parties will
                provide all CCS signaling parameters, including CPN, and will
                honor all privacy indicators.

        F.      Transit Signaling: CLEC may choose to route SS7 signaling
                information (~, ISUP, TCAP) from CLEC's signaling network to
                another CLC's signaling network via PACIFIC's signaling network
                for the purpose of signaling call processing and network
                information between CLEC and the other CLC's network, whether or
                not PACIFIC has a direct-traffic trunk to the terminating
                address, provided that CLEC furnishes PACIFIC with:

                1.      the destination point codes of all the CLC switches to
                        which it wishes to send transit signaling;

                2.      the identity of the STPs in PACIFIC's network in which
                        each DPC will be translated;

                3.      the identity of the STPs in the other signaling network
                        to which such transit signaling will be sent; and

                4.      a letter from the other party authorizing PACIFIC to
                        send such signaling messages.

        CLEC agrees to pay the rates for Transit Signaling as specified in
Attachment 8.

        G.      Either Party may opt at any time to terminate (i.e., overflow)
                to the other Party some or all local exchange traffic and
                intraLATA toll traffic originating on its network, together with
                Switched Access traffic, via Feature Group D or Feature Group B
                Switched Access Service. Either Party may otherwise purchase
                these Switched Access Services from the other Party subject to
                the rates, terms and conditions specified in its standard
                intrastate access tariffs.

                                                                   Attachment 18

        H.      When the Tandem-Level Terminating option is chosen, each Party
                shall deliver to the other Party over the Local Interconnection
                Trunk Group(s) only such traffic which is destined for those
                publicly dialable NPA NXX codes served by end offices that
                directly subtend the Access Tandem or to those LECs, CLCs and
                Wireless Service Providers that directly subtend the Access
                Tandem. When a LATA-Wide Terminating Access option is chosen,
                CLEC may route Local Interconnection traffic to a PACIFIC Access
                Tandem destined for any NXX in the LATA.

        I.      Unless otherwise agreed to, each Party shall deliver all traffic
                destined to terminate at either Party's end office or tandem in
                accordance with the serving arrangements defined in the Local
                Exchange Routing Guide ("LERG").

        J.      Where the Parties deliver over the Local Interconnection Trunk
                Group miscellaneous calls (i.e., time, weather, NPA-555,
                California 900, Mass Calling Codes) destined for each other,
                the'! shall deliver such traffic in accordance with the serving
                arrangements defined in the LERG.

        K.      Nil codes (e.g., 411, 611 and 911) shall not be sent between
                CLEC's and PACIFIC's network over the Local Interconnection
                Trunk Groups.

        L.      Maintenance of Service.

                1.      A Maintenance of Service charge, as specified below
                        (N.3], applies whenever either Party requests the
                        dispatch of the other Party's personnel for the purpose
                        of performing maintenance activity on the
                        interconnection trunks, and any of the following
                        conditions exist:

                        a)      No trouble is found :n the interconnection
                                trunks; or

                        b)      The trouble condition results from equipment,
                                facilities or systems not provided by the Party
                                whose personnel were dispatched; or

                        c)      Trouble clearance did not otherwise require a
                                dispatch and, upon dispatch requested for repair
                                verification, the interconnection trunk does not
                                exceed Maintenance Limits.

                2.      If a Maintenance of Service initial charge has been
                        applied and trouble is subsequently found in the
                        facilities of the Party whose personnel were dispatched,
                        the charge will be canceled.

                3.      Billing for Maintenance of Service is based on each
                        half-hour or fraction thereof expended to perform the
                        work requested. The time worked is categorized and
                        billed at one of the following three rates:

                        a)      basic time;



                                       6
<PAGE>   302

                                                                   Attachment 18

                        b)      overtime; or

                        c)      premium time

                        As defined for billing by PACIFIC in PACIFIC's revised
                        Schedule Cal. P.U.C. Tariff No. 175-T, Section 13 and in
                        CLEC's Exchange tariff.

II.     THIRD-PARTY TRAFFIC

        A.      PACIFIC shall terminate traffic from third-party LECs, CLCs, or
                wireless service providers ("WSPs") delivered to PACIFIC's
                network through an CLEC tandem. Prior to the routing of such
                traffic, the Parties agree to negotiate the issues of network
                capacity and forecasting caused by such terminations. The
                Parties shall conduct such negotiations in good faith and shall
                not unreasonably withhold consent to the routing of such
                traffic.

        B.      PACIFIC shall complete traffic delivered from CLEC destined to
                third-party LECs, CLCs or WSPs in the LATA. PACIFIC shall have
                no responsibility to ensure that any third-party LEC, CLC or WSP
                will accept such traffic.

        C.      PACIFIC shall accept, from any third-party LEC, CLC, or WSP in
                the LATA, traffic destined for an CLEC end office subtending the
                relevant PACIFIC tandem, or a LEC, CLC or WSP subtending CLEC's
                central office if PACIFIC has a provision in ~n interconnection
                agreement with such LEC, CLC or WSP permitting such an
                arrangement.

III.    COMPENSATION FOR CALL TERMINATION

        A.      In all cases, resale lines (whether purchased by CLEC or a third
                party) in PACIFIC's switches will be treated in the same manner
                as PACIFIC's end user customers for the purposes of call
                termination charges.

        B.      For calls that originate from or terminate to an CLEC LSNE,
                bound for or terminated from a third party LEC, the Parties
                agree that PACIFIC shall make arrangements directly with that
                third party for any compensation owed in connection with such
                calls on CLEC's behalf.

        C.      PACIFIC agrees to bill any facilities-based third party referred
                to in B, above, unless, after thirty (30) days' notice in
                writing to PACIFIC, CLEC requests otherwise. To compensate
                PACIFIC for this service, CLEC agrees to pay $.005 (one-half
                cent) per message.

        D.      For calls that originate from a facilities-based third party and
                terminate to an CLEC LSNE, PACIFIC will compensate CLEC on
                behalf of that third party. For calls that terminate to a
                facilities-based third party from an CLEC LSNE,

                PACIFIC has agreed to charge CLEC as if the call terminated in

                                responsible for the measurement of its
                                originating traffic transmitted to the other.
                                The Parties will undertake traffic measurements
                                on a LATA-Wide basis in each LATA where the
                                Parties interconnect. The Parties will report
                                measurements to each other no later than the end
                                of the month following the completion of the
                                quarter. The provisions of this Section and of
                                (b) and (c), below, will not apply until the
                                first full calendar quarter after the effective
                                date of this Agreement. The reported
                                measurements will determine the requirement for
                                payments, if any, for the subsequent full
                                calendar quarter. In determining whether any
                                amount for call terminations owing under this
                                section, neither Party shall be obliged to pay
                                the other unless, on a LATA-Wide basis, the net
                                usage differential (i.e., the difference between
                                the respective Parties' usage levels, calculated
                                by subtracting the lower total number of minutes
                                of use in a quarter from the higher total
                                number) exceeds the following percentages of the
                                total volume of local traffic exchanged between
                                the Parties in the LATA:

                                (i)     The applicable percentage for 0 to
                                        2,000,000 minutes of use will be 10%;

                                (ii)    The applicable percentage for 2,000,001
                                        through 5,000,000 minutes of use will be
                                        5%;

                                (iii)   The applicable percentage for greater
                                        than 5,000,000 minutes of use will be
                                        2%.

                        (b)     The Parties agree that any calculation of net
                                usage differential for local traffic volumes
                                less than the percentages set out immediately
                                above shall demonstrate the Parties' traffic to
                                be in balance for purposes of this Section, The
                                Parties will base calculation under this Section
                                on AMA recordings, which shall be made, where
                                possible, in both the originating and
                                terminating Parties' network. The Parties agree
                                to report to each other on a monthly and
                                quarterly basis the total monthly local minutes
                                of use each terminates to the other Party.

                        (c)     Where the Parties' traffic is not in balance, as
                                determined in the immediately preceding Section,
                                the Party terminating the greater

                                amount of ~ traffic to the other (the
                                "out-of-balance Party") will pay the other
                                Party, for all minutes of use in excess of the
                                number of minutes terminated to it by the other
                                Party, call termination rates based on the
                                following rate elements, per minute of use. The
                                out-of-balance Party will continue to make such
                                payments through the end of the quarter in which
                                it is determined that its traffic is no longer
                                out of balance. Upon such a determination, the
                                payments shall cease until the Parties' traffic
                                is again determined to be out of balance. When
                                traffic exchanged is out of balance, the
                                out-of-balance Party shall pay

                                (i)     Local Switching Capacity,

                                (ii)    Tandem Switching (where used), and

                                (iii)   Common Transport (where used).

                        (d)     Once the Commission has established rates for
                                Local Call transport and termination in its Open
                                Access and Network Architecture Development
                                ("OANAD") proceeding, those rates shall apply in
                                lieu of the above-specified rate elements.

                2.      For Local and intraLATA Toll traffic originated by CLEC
                        (or CLCs subtending its network) to PACIFIC, CLEC agrees
                        to pay PACIFIC the following:

                        (a)     Local calls: Bill and Keep (applicable to all
                                local Zone Usage Measurement ("ZUM") Zone 1,
                                Zone 2 and Zone 3, and Extended Area Service
                                traffic) shall apply unless the Parties' traffic
                                is out of balance per subsection 1(a) of this
                                Section, above. In the latter event, the
                                provisions of Subsection 1(c) of this Section
                                shall apply.

                        (b)     Toll calls: The following rate elements are
                                applicable to intraLATA toll calls, based on the
                                rates in Attachment 8.

                                (1)     The following rate elements from
                                        PACIFIC's Tariff Cal. PUC 1 75-T will
                                        apply when a Toll Call routes over Local
                                        Interconnection Trunk Groups:

                                (a)     For common switched transport: where
                                        PACIFIC's tandem is used:

                                       (i)     Fixed - per minute of use.

                                       (ii)    Variable - per mile per minute of
                                               use. Mileage shall be calculated
                                               based on the

                                               PACIFIC end office or CLC routing
                                               point.

                                       (iii)   Tandem Switching.

                                (2)     CLEC will pay two times the Tandem
                                        Switching rate as specified in
                                        Attachment 8 if whenever CLEC elects the
                                        LATA-Wide Terminating Option.

               3.     For Local and intraLATA Toll traffic originated from
                      PACIFIC to CLEC, PACIFIC agrees to pay CLEC the following:

                      (a)    Local calls: Bill and Keep: (applicable to all
                             local Zone Usage Measurement ("ZUM") Zone 1, Zone 2
                             and Zone 3, and Extended Area Service traffic)
                             shall apply unless the Parties' traffic is out of
                             balance per Section Fl(a), above. In the latter
                             event, the provisions of Section F1(c) shall apply.

                      (b)    Toll calls: The following rate elements from
                             PACIFIC's Tariff Cal. PUC 175-T will apply when a
                             toll call routes over Local Interconnection Trunk
                             Groups:

                             (1)    For common switched transport:  
                                    where CLEC's tandem is used:

                                    (i)     Fixed - per minute of use.

                                    (ii)    Variable - per mile per minute of
                                            use. Mileage shall be calculated
                                            based on the airline miles between
                                            the Vertical and Horizontal ("V&H")
                                            coordinates of the P01, and the CLEC
                                            end office or CLC/CLEC routing
                                            point.

                             (2)    Tandem Switching

                             (3)    Local switching

                                                                   Attachment 18

        G.      Tandem Transit Switching rate: Tandem Transit Switching rate
                shall be equal to the Tandem Switching rate plus two times the
                Common Transport Fixed rate element as specified in Attachment
                8.

                1.      The transit rate provides for Access Tandem switching
                        when either Party uses the other Party's Access Tandem
                        to originate a CLC call to a third party such as another
                        LEC, CLC, or Wireless Service Provider.

                2.      If either Party receives a call through the other
                        Party's Access Tandem that originates from another LEC,
                        CLC or wireless service Provider, the Party receiving
                        the transited call will not charge the other Party any
                        rate element for this call regardless of whether the
                        call is local or toll. The Parties will establish
                        appropriate billing relationships directly with the
                        Wireless Service Provider, other CLC or LEC.

        H.      For intraLATA Toll Free Service calls where such service is
                provided by one of the Parties, the compensation set forth in
                Section III. above, shall be charged by the Party originating
                the call, rather than the Party terminating the call. This
                includes originating charges listed in Section III as well as a
                database query charge as specified in PACIFIC's intrastate
                access tariff or CLEC's local exchange tariff.

        I.      Each Party will calculate terminating interconnection minutes of
                use based on standard Automatic Message Accounting ("AMA")
                recordings made within each Party's network. These recordings
                are the basis for each Party to generate bills to the other
                Party. Either Party may request the exchange of originating EMR
                records in order to bill the other Party terminating minutes of
                use. The Parties agree to cooperate in the exchange of the
                records if so requested.

        J.      Measurement of minutes of use over Local Interconnection Trunk
                Groups shall be in actual conversation seconds. The total
                conversation seconds over each individual Local Interconnection
                Trunk Group will be totaled for the entire monthly bill and then
                rounded to the next whole minute.

        K.      Each Party will provide the other, within fifteen (15) calendar
                days after the end of each calendar quarter, a usage report with
                the following information regarding traffic it sent to (i.e.,
                terminated over) the Local Interconnection Trunk arrangements:

                1.      Total traffic volume described in terms of minutes and
                        messages and by call type (local, toll and other)
                        terminated to each other over the Local Interconnection
                        Trunk Groups; and

                2.      Percent Local Usage (PLU)

        L.      CLEC will pay the rates for SS7 CCS interconnection as specified
                in Attachment 8. The Parties will exchange TCAP messages to
                facilitate full interoperability of CCS-based features and
                functions, to the extent each carrier offers such features and
                functions to its own end users. All CCS signaling parameters
                will be provided, including CPN. All privacy indicators will be
                honored.

        M.      For 976 or California 900 calls (those 900 NXXs shown in the
                LERG as PACIFIC's 900 NXXs), CLEC shall deliver calls originated
                over CLEC-provided exchange services to the Local
                Interconnection Trunk Groups. The Parties have separately
                reached agreement on the rating and billing of such calls.

IV.     COMPENSATION FOR USE OF LOCAL INTERCONNECTION FACILITIES

        A.      Interconnection facilities include the facilities that connect
                the Parties' respective switching networks.

        B.      The Parties agree that each has an equal obligation to
                interconnect its network infrastructure to the other's network.
                The Parties may decide to own the interconnection facility
                jointly or to provide facilities to deliver traffic to the
                other. If the Parties agree to build the interconnection
                facilities, they will agree on desired capacity and performance
                characteristics and then may bid to install the facilities. The
                Party with the lowest bid will construct the facilities and bill
                the other Party 50% of the construction costs. The constructing
                Party will charge a monthly maintenance charge for maintaining
                the facilities. This charge will be based upon the TELRIC of
                maintaining the facility. (Solely for the purpose of this
                paragraph, TELRIC shall be defined as did the FCC in the First
                Interconnection Order.) !f the Parties decide not to build and
                operate the interconnecting facility jointly, they may choose
                from options 1 or 2 below.

        C.      The Parties agree to the following terms based on consideration
                of the generally balanced use of the Parties' respective
                facilities for interconnection. Such consideration is based on
                relative facility length the capacity provided to each other,
                determined by the comparison of facility deployment behind the
                POIs associated with CLEC collocation arrangements and PACIFIC's
                network. This compensation is contingent on a balanced facility
                interconnection being defined in Appendix A.

                1.      Where the P01 for the Local Interconnection Trunk Group
                        is located other than in the same PACIFIC Wire Center as
                        the PACIFIC switch where the Local Interconnection Trunk
                        Group terminates, CLEC will pay a monthly charge for the
                        PACIFIC-provided facility according to PACIFIC's
                        intrastate access tariff, in addition to any usage rate
                        elements in Section III above. CLEC may, at its option,
                        choose to pay PACIFIC either the applicable PACIFIC
                        tariffed unbundled transport or unbundled interoffice

                                                                   Attachment 18

                        facility rates for DS-1 rates for those DS-1(s) used for
                        Local Interconnection Trunks in a DS-3 facility, or pay
                        the applicable tariffed or unbundled interoffice
                        facility rates for DS-3 for each DS-3 facility, used for
                        Local Interconnection Trunks between the Parties.

                2.      Where the P01 for the Local Interconnection Trunk Group
                        is at a collocation arrangement in the same PACIFIC Wire
                        Center as the PACIFIC switch where the Local
                        Interconnection Trunk Group terminates, PACIFIC will pay
                        CLEC a monthly charge for the facility and cross connect
                        equal to one Point Of Termination at DS-1 rates (per
                        DS-1(s) used for Local Interconnection Trunks) or DS-3
                        rates (per DS-3 used for Local Interconnection Trunks)
                        according to Pacific's intrastate access tariff, in
                        addition to any usage rate elements, if any, above.
                        PACIFIC may, at its option, choose to pay either the
                        applicable tariffed DS-1 rates for those DS-1(s) used
                        for Local Interconnection Trunks in a DS-3 facility, or
                        pay the applicable tariffed DS-3 rates for each DS-3
                        facility used for Local Interconnection Trunks between
                        the Parties.

                3.      Where the P01 for the Local Interconnection Trunk Group
                        is at a Mid Span Meet, there shall be no compensation
                        between the Parties for the Local Interconnection
                        facilities used.

V.      MEET-POINT TRUNKING ARRANGEMENTS

        A.      Two-way trunks will be established to enable CLEC and PACIFIC
                jointly to provide Feature Group B and D ("FGB and FGD")
                Switched Access Services via PACIFIC's Access Tandem switch.

        B.      CLEC may use Meet-Point Trunks to send and receive FGB and FGD
                calls from Switched Access customers connected to PACIFIC's
                Access Tandem.

        C.      The Parties will use separate facilities and separate two-way
                trunk groups to each and every PACIFIC Access Tandem under which
                CLEC's NXXs home using DS-1 or DS-3 facilities other than the
                facilities used for Local Interconnection Trunk Groups. Neither
                Party will charge the other any amount for any meet-point
                facilities.

        D.      In the case of Switched Access Services provided through
                PACIFIC's Access Tandem, PACIFIC will not offer blocking
                capability for Switched Access customer traffic delivered to
                PACIFIC's tandem for completion on CLEC's network. The Parties
                understand and agree that Meet-Point Trunking arrangements are
                available and functional only to or from Switched Access
                customers who directly connect with PACIFIC's tandems that CLEC
                subtends in each LATA. In no event will PACIFIC be required to
                route such traffic through more than one tandem for connection
                to or from Switched Access customers. 



                                       21
<PAGE>   317

                                                                   Attachment 18

                PACIFIC shall have no responsibility to ensure that any Switched
                Access customer will accept traffic that CLEC directs to the
                Switched Access customer. PACIFIC also agrees to furnish CLEC a
                list of those IXCs which also interconnect with PACIFIC's
                tandems.

        E.      The Parties will provide CCS to one another, where and as
                available, in conjunction with meet-point two-way trunk groups.
                CLEC may establish CCS interconnections (either directly or
                through a third party), provided such third-party is
                interconnected with PACIFIC pursuant to inter- and intra-state
                access tariffs. The Parties will exchange TCAP messages to
                facilitate full inter-operability of CCS-based features between
                their respective networks, including all CLASS features and
                functions, to the extent each carrier offers such features and
                functions to its own end users. CLEC will provide all CCS
                signaling including, without limitation, Charge Number and
                originating line information ("OLI"). For terminating FGD,
                PACIFIC will pass all CCS signaling including, without
                limitation, CPN if it receives CPN from FGD carriers. All
                privacy indicators will be honored. Where available, network
                signaling information such as Transit Network Selection ("TNS")
                parameter, Carrier Identification Codes ("CIC"), (CCS platform)
                and CICIOZZ information (non-CCS environment) will be provided
                by CLEC wherever such information is needed for call routing or
                billing. The Parties will follow all OBF adopted standards
                pertaining to TNS and CIC/OZZ codes.

        F.      The Parties shall use CCS in conjunction with Meet-Point Trunks,
                provided that they must use multifrequency ("MF") signaling on a
                separate Meet Point Trunk group for originating FGD access to
                Switched Access customers that use MF FGD signaling protocols
                and may use such signaling due to equipment constraints. The
                Parties shall not provide MF and CCS trunk within a DS-1
                facility. They must use a separate DS-1 facility for each
                signaling type.

        G.      CLEC shall deliver all originating Toll Free Service calls for
                which it requests that PACIFIC perform the Service Switching
                Point ("SSP") function (e.g., performs the database query) using
                GR-394 format over the Meet-Point Trunk group. CLEC shall use
                Carrier Code "0110" and Circuit Code of "08" for all such calls.

        H.      When CLEC performs the SSP function for Toll Free service calls,
                and if such calls are destined for an IEC, if CLEC delivers such
                calls to PACIFIC it shall do so over Meet Point Trunk Groups
                using GR-394 format. When CLEC performs the SSP function for
                Toll Free service calls, and if such calls are destined for NXXs
                within the LATA, if CLEC delivers such calls to PACIFIC, it
                shall do so over the Local Interconnection Trunk Group using
                GR-317 format.

                                                                   Attachment 18

        I.      Originating Feature Group B calls delivered to PACIFIC's tandem
                shall use GR-317 signaling format unless the associated FGB
                carrier employs GR-394 signaling for its FGB traffic at the
                serving Access Tandem.

VI.     RESPONSIBILITIES OF THE PARTIES

        A.      CLEC and PACIFIC agree to exchange such reports and/or data as
                provided in this Attachment to facilitate the proper billing of
                traffic. Either Party may request an audit of such usage reports
                on no fewer than ten (10) business days written notice and any
                audit shall be accomplished during normal business hours at the
                office of the Party being audited (which shall be San Francisco
                for CLEC and San Francisco for PACIFIC). Such audit must be
                performed by a mutually agreed-to auditor paid for by the Party
                requesting the audit. Such audits shall be requested within six
                months of having received the PLU factor and usage reports from
                the other Party and may not be requested more than twice per
                year.

        B.      CLEC and PACIFIC will review engineering requirements on a
                semi-annual basis and establish guidelines for forecasts of
                trunk and facilities utilization provided under this Attachment.

        C.      CLEC and PACIFIC shall share responsibility for all Control
                Office functions for Local Interconnection Trunks and Trunk
                Groups, and both Parties shall share the overall coordination,
                installation, and maintenance responsibilities for these trunks
                and trunk groups.

        D.      CLEC is responsible for all Control Office functions for Meet
                Point Trunks and Trunk Groups, and shall be responsible for the
                overall coordination, installation, and maintenance
                responsibilities for these trunks and trunk groups.

        E.      CLEC and PACIFIC shall:

                1.      Provide trained personnel with adequate and compatible
                        test equipment to work with each others' technicians.

                2.      Notify each other when there is any change affecting the
                        service requested, including the due date.

                3.      Coordinate and schedule testing activities of their own
                        personnel, and others as applicable, to ensure its
                        interconnection trunks/trunk groups are installed per
                        the interconnection order, meet agreed upon acceptance
                        test requirements, and are placed in service by the due
                        date.

                4.      Perform sectionalization to determine if a trouble is
                        located in its facility or its portion of the
                        interconnection trunks prior to referring the trouble to
                        each other.



                                       23

                                                                   Attachment 18

                5.      Advise each other's Control Office if there is an
                        equipment failure that may affect the interconnection
                        trunks.

                6.      Provide each other with a trouble reporting number that
                        is readily accessible and available 24 hours/7 days a
                        week.

                7.      Provide to each other test-line numbers and access to
                        test lines, including a test-line number that returns
                        answer supervision in each NPA-NXX opened by a Party.

        F.      CLEC and PACIFIC will provide their respective billing contact
                numbers to one another on a reciprocal basis

        G.      The Parties will conduct cooperative testing for the proper
                recording of AMA records in each carrier switch(es) before
                establishing service.

        H.      Prior to the time of interconnection, CLEC will provide to
                PACIFIC CLEC's references or internal standards governing each
                topic in the Bilateral Agreement Template/Worksheet attached as
                Appendix B, for which there is a corresponding PACIFIC
                reference.

VII.    INSTALLATION OF TRUNKS

        Due dates for the installation of Local Interconnection Trunk Groups and
        Meet Point Trunks covered by this Agreement shall be equal to PACIFIC's
        Switched Access intervals.

VIII.   TRUNK FORECASTING

        A.      The Parties shall work towards the development of joint
                forecasting responsibilities for traffic utilization over trunk
                groups. Orders for trunks that exceed forecasted quantities for
                forecasted locations will be accommodated as facilities and/or
                equipment becomes available. The Parties must provide forecast
                information to each other twice a year. The forecasting Service
                Performance Measures and Liquidated Damages (Attachment 17 to
                this Agreement) shall not apply to the following forecasts. The
                semi-annual forecasts shall include:

               1.     Yearly forecasted trunk quantities (which include
                      measurements that reflect actual tandem Local
                      Interconnection and Meet Point Trunk Groups and end office
                      equivalent trunking requirements, whether or not tandem
                      subtending) for a minimum of three (current and plus-i and
                      plus-2) years;

               2.     The use of Common Language Location Identifier, described
                      in Bellcore documents BR 795-100-100 and BR 795400-100
                      and;



                                       24
<PAGE>   320

                                                                   Attachment 18

               3.     A description of major network projects anticipated for
                      the following six months. Major network projects include
                      trunking or network rearrangements, shifts in anticipated
                      traffic patterns, or other activities that are reflected
                      by a significant increase or decrease in trunking demand
                      for the following forecasting period.

        B.      If differences in semi-annual forecasts of the Parties vary by
                more than 48 additional DSO two-way trunks for each Local
                Interconnection Trunk Group, the Parties shall meet to reconcile
                the forecast to within 48 DSO trunks.

        C.     If a trunk group is under 75 percent (75%) of centum call seconds
               capacity on a monthly average basis for each month of any
               six-month period, either Party may request the issuance of an
               order to resize the trunk group, which shall be left with not
               less than 25% excess capacity. In all cases, grade-of-service
               objectives identified in Section IX, following, shall be
               maintained.

        D.     Each Party shall provide a specified point of contact for
               planning, forecasting and trunk servicing purposes.

IX.     GRADE OF SERVICE

        A blocking standard of one half of one percent (.005) during the average
        busy hour, for final trunk groups between the Parties' networks carrying
        Meet-Point traffic shall be maintained. All other final trunk groups
        shall be engineered with a blocking standard of one percent (.01)

X.      LOCAL INTERCONNECTION TRUNK SERVICING

        A.      Orders between the Parties to establish, add, change or
                disconnect trunks shall be processed by use of an
                Interconnection Service Request ("ISR") for CLEC orders to
                PACIFIC or an Access Service Request "ASR" for PACIFIC orders to
                CLEC.

        B.      The Parties will jointly manage the capacity of Local
                Interconnection Trunk Groups. PACIFIC's Circuit Provisioning
                Assignment Center ("CPAC") and CLEC's equivalent center will
                send a Trunk Group Service Request ("TGSR") to the other Party
                to trigger changes to the Local Interconnection Trunk Groups
                based on capacity assessment. Either Party upon receipt of the
                TGSR will issue an ISRIASR to the other Party:

                1.      Within 10 business days after receipt of the TGSR; or

                2.      At any time as a result of either Party's own capacity
                        management assessment, in order to begin the
                        provisioning process.

        C.      Orders that comprise a major project shall be submitted at the
                same time, and their implementation shall be jointly planned and
                coordinated. Major projects are those

                                                                   Attachment 18

        that require the coordination and execution of multiple orders or
        related activities between and among PACIFIC and CLEC work groups
        including, but not limited to, the initial establishment of Local
        Interconnection or Meet Point Trunk Groups and service in an area, NXX
        code moves, re-homes, facility grooming, or network rearrangements.

        D.      The Parties will cooperate to establish separate high-volume
                trunk groups for the completion of calls to high volume
                customers, such as radio contest lines.

        E.      CLEC will be responsible for engineering its network on its side
                of the P01. PACIFIC will be responsible for engineering its
                network on its side of the P01.

XI.     TROUBLE REPORTS

        CLEC and PACIFIC will cooperatively plan and implement coordinated
        repair procedures for the Meet Point and Local Interconnection Trunks
        and facilities to ensure that trouble reports are resolved in a timely
        and appropriate manner consistent with procedures referenced in Section
        VI of this Attachment.

XII.    NETWORK MANAGEMENT

        A.      Protective Controls Either Party may use protective network
                traffic management controls, such as 7-digit and 10-digit code
                gaps, on traffic toward each other's network, when required to
                protect the public switched network from congestion due to
                facility failures, switch congestion or failure, or focused
                overload. CLEC and PACIFIC will immediately notify each other of
                any protective control action planned or executed.

        B.      Expansive Controls Where the capability exists, either Party may
                implement originating or terminating traffic reroutes to relieve
                network congestion temporarily due to failures or abnormal
                calling patterns. Reroutes will not be used to circumvent normal
                trunk servicing. Expansive controls will only be used when the
                Parties mutually agree.

        C.      Mass Calling CLEC and PACIFIC shall cooperate and share
                pre-planning information regarding cross-network call-ins
                expected to generate large or focused temporary increases in
                call volumes.

           FOR THE PURPOSE OF CONNECTING TO THE AMES INTERNET EXCHANGE

1.0     AUTHORITY

        This Reimbursable Space Act Agreement (RSAA) is entered into by CRL
Network Services, Inc. (hereinafter referred t6 as the Participant) with a place
of business at San Francisco, CA, and the NATIONAL AERONAUTICS AND SPACE
ADMINISTRATION, Ames Research Center located at Moffett Field, California
94035-1000 ("NASA"). The legal authority for NASA to enter into this agreement
is found in sections 203(c)(5) and (6) of the Space Act of 1958, 42 USC
Section 2473(c).

2.0     PURPOSE

        This RSAA shall be effected for the purpose of:

               (a)    adding Participant to a unique collocated network
                      interconnect in vivo testbed in which Participants
                      exchange data among their client networks as well as with
                      NASA networks and other cooperating commercial and Federal
                      networks that are similarly attached at this testbed which
                      is known as MAE-West (Metropolitan Area Exchange - West
                      Coast) which is part of the Ames Internet Exchange;

               (b)    facilitating (1) the metering and analysis of internet
                      traffic flows, (2) the study of new algorithms for caching
                      internetwork flows, and (3) the development of new
                      approaches to traffic moderation by aggregating
                      Participants on a common testbed to share in the resulting
                      costs and benefits;

               (c)    providing new technology transmission facilities, either
                      terrestrial or satellite, that stimulate competition and
                      cost moderation as new network capabilities are introduced
                      by Participants; use of such new technology is essential
                      to efficient operation of NASA and other Federal networks;

        The foregoing statements of purpose (a) to (c) support NASA-Ames
Research Centers role as NASA lead center for Information Systems Technology.

        This interconnect testbed shall be located at NASA Ames Research Center
along with associated collocated equipment required to establish network
connectivity. This RSAA will benefit NASA by enhancing the ability of the
NASA-Ames Research Center to meet its 



                                       1
<PAGE>   5

responsibility to provide for a logical extension to the existing Federal
Interconnect Exchange - West Coast facility (FD( - West) that is managed by NASA

        Ames Research Center Information Services Division and is also part of
the Ames Internet Exchange. In attaining this objective, it will ensure that all
costs to the government are offset by fees paid by those Participants connecting
to MAE-West.

        This agreement is for both the network connecting the Participants to
the Internet at MAE-West, a unique collocated interconnect facility located at
NASA-Ames, and for operating a satellite terminal collocated near MAE-West. No
agreement expressed or implied, is hereby made to order or provide communication
services to NASA or the U.S. Government. Both parties will use reasonable
efforts to meet performance provisions under this RSAA.

3.0     RESPONSIBILITIES

        3.1    PARTICIPANT RESPONSIBILITIES

        The Participant will provide the following materials, effort and
information to NASA:

        1.  The Participant shall provide all equipment required to properly
attach its network facilities to the facilities at MAE-West, such as routers,
CSU/DSU's, etc. including all required cabling, and shall provide up to date
configuration drawings to NASA to insure that adequate information is available
for trouble shooting requirements. The Participant shall provide for reasonable
maintenance and support agreements for any of its equipment located at NASA Ames
Research Center and shall ensure that any third party personnel requiring access
to their equipment are cognizant of all terms and conditions in this Agreement,
including the requirement of U.S. citizenship.

        2.  The Participant shall provide required telecommunications
transmission services such as DS-3 leased lines, ATM facilities, etc. and shall
provide NASA with copies of any related orders for such services when they
occur, to assure coordinated delivery and installation of such services by
NASA's Resident Staff.

        3.  The Participant shall provide out-of-band (OOB) network
management for all active devices such as routers, CSU/DSU's, etc. to minimize
the support required from NASA for emergency trouble shooting of equipment. The
Participant shall provide all required telecommunications links (such as
switched analog voice lines for dialup modems, etc.) to support this OOB
management.

        4.  The Participant shall provide a detailed implementation plan
including configuration, installation, and operation of equipment that is to be
attached to MAE-West, within 30 days of the signature of this Agreement, and the
RSAA must be approved by NASA before any work commences unless waived in writing
by NASA. If the Participant enters separate agreements between itself and
Network Service Providers (peering agreements), Participant shall designate the
names of such Network Service Providers (NSPs) to NASA as part of the
implementation plan.

               (i)    maintenance of an inventory of Participant's decaled
                      equipment and support of their property management system.

        2.  NASA will provide access to related telecommunications carrier
facilities (e.g. Pacific Bell, Metropolitan Fiber Systems, etc.) that are
collocated in the same facility as MAE-West for termination of Participant
provided telecommunications services (e.g., DS-3 leased line facilities, FDDI
fiberoptics, etc.). However, NASA is not responsible for providing said services
themselves nor is it responsible for setting costs for such services except such
costs as accrue to the government.

        3.  NASA will provide access to the MAE-West facilities, currently an
FDDI Ring, and future access to one port on new technology switch when it is
acquired and installed. This switched facility (e.g., a DEC GIGAswitch) will be
operated and managed by NASA 24 hours per day, seven (7) days per week, 52 weeks
per year (24x7x52), and provide reliable, high performance transport of network
traffic between the Participant's equipment and other NSPs that are attached
directly to MAE-West NASA will maintain this configuration and ensure that
changes are adequately coordinated with Participants.

        4.  NASA will provide access to designated staff of the Participant
or their designees for maintenance and trouble shooting of Participant's
equipment Emergency access to equipment located at MAE-West will be provided by
NASA within a two (2) hour period after a request has been made, including
off-hours. NASA will also provide Resident Technician emergency support for
trouble shooting problems with Participant equipment, such as power cycling or
physical resetting of equipment within two (2) hours of a request being made, in
case normal OOB management capabilities cannot provide equivalent functionality.

        Note the existence of access restrictions: all Participant staff,
including third party staff with whom Participant may contract for services,
e.g., maintenance, that are allowed on-site access must be U.S. citizens and
they must obtain prior written consent by NASA to visit the site, either
on-shift or off-shift; no foreign nationals are allowed on-site access. NASA
will escort approved Participant staff or their designees while work is being
performed on-site at NASA Ames Research Center, and will insure proper
identification, documentation and authentication as well as in/out logging.
Off-shift access to Moffett Field will require escort by NASA Resident Staff
through the Main Gate. On-shift access is Monday through Friday, 0700 to 1615
hours.

        5.  NASA will provide monthly traffic statistics of data exchanged
among MAE-West participants only with written consent from NSPs. NASA may
monitor network layer traffic for purposes of Research and Development
consistent with its mission. NASA reserves the right to monitor end user data of
Government agency networks attached to MAE-West to insure appropriate use of
Government network facilities involved with MAE-West.

        6.  NASA will perform the installation and cabling of all of the
Participant's equipment as per the layout that is included in the Participant's
implementation plan. Installation will be performed in accordance with current
standards as set forth in paragraph 9.0 Reference A of this agreement

                                       4
<PAGE>   8

        7.  NASA will provide one business week's notice for normal
maintenance of facility systems.

        8.  NASA will, at its discretion, provide information other than
traffic statistics on NSPs that are connected to FIX-West or MAE-West NASA shall
not accept requests for non-disclosure for any data that are not traffic
statistics or designated as Participant Produced Data in paragraph 6.3 of this
agreement NASA is not responsible for peering agreements among Participants but
will facilitate such agreements whenever it can do so.

                            SPRINT NAP ACCESS TYPES

To promote a variety of access methods Sprint has established two options for 
customer connectivity to the NAP. These are outlined below.

Type I

The NSP terminates a DS3 or OC-3 circuit to an NSP-provided router collocated 
at the Sprint NAP. This connection type allows the placement of a 
customer-owned router at the NAP with direct attachment to FDDI ports on the 
NAP. The IXC service provider is of the NSP's selection. The minimum 
transmission rate is DS3.

Customer must provide the DS3 CSU/DSU and router HSSI cable. Sprint will 
provide the FDDI multimode fiber cabling to connect the customer's router to 
the NAP.

                       Figure 1. Type I NAP Access Method



Note: For reasons of space planning and configuration control, each collocated
      router is permitted to terminate a maximum of three (3) DS3s or one (1)
      OC-3 circuit from the NSP's backbone.

TYPE II
- -------

The NSP-provided router terminates an ATM network DS3 or OC-3 circuit using
Sprint's ATM User-to-Network Interface (UNI) at the Sprint NAP. This connection
type allows the placement of a customer-owned router at the NAP with direct
attachment to FDDI ports on the NAP. The minimum transmission rate is DS3.

Sprint will provide the FDDI multimode fiber cabling to connect the customer's 
router to the NAP.

                            NAP COLLOCATED EQUIPMENT


1. INSTALLATION SPECIFICATIONS

The Customer is responsible for installing and maintaining their equipment at 
the Sprint NAP in accordance with the following specifications:

        - Equipment must be UL approved
        - Equipment must support 120Vac power (see note)
        - Rackmount shelves must have rack-mount ears for flush mounting to
          rack standoffs
        - Rackmount shelves must have manufacturer-supplied cable management
          brackets
        - Rackmount shelf width must be no more than 17.72 inches
        - No open shelf slots are permitted (e.g., vacant slots must be
          covered)

Note:  Redundant 48Vdc power is available for Cisco 7507 or similar sized 
       router. Consult with Spring NAP Engineering for details.

In addition, the Customer is responsible for ensuring that the standards by 
which the equipment is installed are consistent with industry standards and 
practices.

2. FACILITY ACCESS

The Customer will be granted access into the Sprint NAP facility during normal 
business hours. Access for emergency repairs only on a 24 x 7 basis is also 
available. In both cases, prior arrangements must be made by contacting NAP 
Engineering. NAP Engineering will coordinate customer technician access into 
the Sprint facility. Sprint will endeavor to accommodate requests for after 
hours or weekend upgrades to existing equipment. No installation, maintenance 
or non-emergency repair of equipment after hours or on weekends/holidays will be
allowed without prior arrangements having been made. Installation of new 
equipment requires a minimum of two (2) business days confirmed advance notice.

3. SPECIFICATIONS OF CUSTOMER COLLOCATED EQUIPMENT

The customer is required to submit his desired equipment configuration to the 
NAP Engineering and receive approval before collocation can proceed. Equipment 
specifications such as rackmount shelf dimensions, power requirements, heat 
dissipation and other pertinent information are required by NAP Engineering so 
as to determine customer equipment rack mounting configuration and bay mounting 
assignments. NAP Engineering will provide customer with an installation 
specification document prior to the scheduled installation date at the NAP.

4. RACK MOUNTING

Sprint will provide standard open 19-inch relay racks. EIA-drilled, with 5-inch 
rack standoffs. Shelf dimensions must not exceed 17.72" in width. Sprint will 
provide UPS-protected 120Vac power for the customer's equipment.

5.  MANAGEMENT PORT ACCESS

    If the Customer requires out-of-band dialup access to their equipment, they
    will need to supply the necessary equipment and order the necessary business
    lines from the Bell Atlantic Business Office. The Customer will be
    responsible for all expenses associated with the use of the business lines.
    The customer must obtain a bay assignment from NAP Engineering before the
    order can be placed with Bell Atlantic.

    For other remote management requirements, such as private network links,
    Spring will cooperate with the Customer. All costs will be born by the
    Customer. The installed equipment will need to meet the same requirements as
    those set out here for similar equipment.


6.  IP ADDRESS ASSIGNMENT

    The customer shall receive his IP address assignment(s) from Sprint. Any
    address(es) provided by Sprint shall remain the property of Sprint and must
    be relinquished upon customer disconnect of NAP services. Sprint shall also
    assign with each customer's NAP IP address a DNS name from the
    SPRINTNAP.NET domain.


7.  SECURITY

    While Sprint makes no requirements in the area of security management for
    NAP clients, it recommends that the Customer develop a policy that addresses
    the traditional information system security issues of acceptable use,
    accountability, and incident handling and recovery for their equipment.

                  (a) adding Participant to a unique collocated network
                      interconnect in vivo testbed in which Participants
                      exchange data among their client networks as well as with
                      NASA networks and other cooperating commercial and Federal
                      networks that are similarly attached at this testbed which
                      is known as MAE-West (Metropolitan Area Exchange - West
                      Coast) which is part of the Ames Internet Exchange;

                  (b) facilitating (1) the metering and analysis of internet
                      traffic flows, (2) the study of new algorithms for caching
                      internetwork flows, and (3) the development of new

its responsibility to provide for a logical extension to the existing Federal
Interconnect Exchange -- West Coast facility (FIX - West) that is managed by
NASA Ames Research Center Information Services Division and is also part of the
Ames Internet Exchange. In attaining this objective, it will ensure that all
costs to the government are offset by fees paid by those Participants connecting
to MAE-West.

        This agreement is for both the network connecting the Participants to
the Internet at MAE-West, a unique collocated interconnect facility located at
NASA-Ames, and for operating a satellite terminal owned by the Participants and
collocated near MAE-West. No agreement expressed or implied, is hereby made to
order or provide communication services to NASA or the U.S. Government. Both
parties will use reasonable efforts to meet performance provisions under this
RSAA.

                  resetting of equipment within two (2) hours of a request being
                  made, in case normal OOB management capabilities cannot
                  provide equivalent functionality.

        Note the existence of access restrictions: all Participant staff,
including third party staff with whom Participant may contract for services,
e.g., maintenance, that are allowed on-site access must be U.S. citizens and
they must obtain prior written consent by NASA to visit the site, either
on-shift or off-shift no foreign nationals are allowed on-site access. NASA will
escort approved Participant staff or their designees while work is being
performed on-site at NASA Ames Research Center, and will insure proper
identification, documentation and authentication as well as in/out logging.
Off-shift access to Moffett Field will require escort by NASA Resident Staff
through the Main Gate. On-shift access is Monday through Friday, 0700 to 1615

                      paragraph 8.6 (a) above.

                  (b) Either party may terminate this Agreement at any time

                      written notice to the other party sixty (60) days before

<PAGE>   4
                             OFFICE LEASE AGREEMENT

        This Office Lease Agreement (the "Lease") is made and entered into as of
the date the last party signed hereon, between Maria Chen, an individual
("Landlord"), and CRL Network Services Inc., a California corporation
("Tenant").

                                    RECITALS

        A. Landlord owns that certain space consisting of approximately 4,650
rentable square feet, together with the fixtures, personal property and
appurtenances thereto (the "Premises") on the tenth (10th) floor of the building
located at and known as One Kearny Street, San Francisco, California (the
"Building"), all as more particularly described on Exhibit A hereto.

        B. Landlord desires to lease the Premises to Tenant, and Tenant desires
to lease the Premises from Landlord, all on the terms and conditions set forth
herein.

        C. Tenant currently leases premises (the "Current Premises") on the
fifth (5th) floor of the Building pursuant to that certain Office Lease
Agreement dated as of July 15, 1994, between Landlord and Tenant (the "Current
Lease")

        NOW, THEREFORE, in consideration of the mutual promises and covenants
contained herein, the parties hereto agree as follows:

        1. Agreement to Lease Premises: Delivery of Possession.

               a. Lease Covenant. Landlord hereby leases to Tenant, and Tenant
hereby leases from Landlord, the Premises, all on the terms and conditions set
forth herein. Tenant acknowledges that the Premises are being leased "as is,"
and that Landlord or Landlord's agents or employees have not made any
representation or warranty, whether oral or written, to Tenant with respect to
the condition of the Premises. Tenant's taking possession of the Premises on the
Commencement Date shall constitute Tenant's express acknowledgment that the
Premises were delivered by Landlord in good condition and, in any event, in a
condition acceptable to Tenant. Tenant further acknowledges that it has
conducted its own due diligence investigation on both the Building and the
Premises, and has satisfied itself as to each and every item and matter relevant
to its decision to enter into this Lease, and that the Building and the Premises
are suitable in all respects for the use intended. Tenant acknowledges that it
is accepting the Premises "AS IS" and with all faults, except that Landlord
represents to Tenant that the Premises are in compliance with current,
applicable laws, rules and regulations, including, without limitation, the
Americans with Disabilities Act. Tenant specifically agrees that Landlord has no
duty to make any disclosures concerning the condition of the Building and the
Premises and/or the fitness of the Building and the Premises for Tenant's
intended use, and Tenant expressly waives any duty which Landlord may have to
make any of said disclosures; provided, however, that Landlord represents that
the Premises are serviced by a functioning heating and air conditioning system
(including the two in-ceiling air conditioners) , that electrical plugs and


                                       1
<PAGE>   5
lights in the Premises are functioning, and that window coverings in the
Premises, if any, are in working order

               b. Delivery of Possession. In the event that Landlord is unable
to deliver possession of the Premises to Tenant by the Commencement Date, Tenant
agrees that Landlord shall not be liable for any damage to Tenant and that this
Lease shall not be void or voidable, but Tenant shall not be liable for any
Rent, as defined below, until such time as Landlord tenders delivery of
possession of the Premises to Tenant; provided, however, that if Landlord does
not deliver possession of the Premises to Tenant on or before a date forty-five
(45) days after the Commencement Date, this Lease shall then become voidable at
the option of either party upon ten (10) days' written notice to the other
party.

               c. Antenna and Conduit License Subject to delivery of possession
of the Premises as contemplated herein, and in view of Tenant's existing rights
with respect to the Current Lease, Landlord hereby grants Tenant a license (the
"License") to (i) install and use an antenna on the roof of the Building and to
connect the same to the Premises, and (ii) connect the Premises to Tenant's
offices at 49 Geary Street, Suite 211, San Francisco, California, by means of a
conduit on the outside of the Building. The term of the License shall be
concurrent with the Term of the Lease. Installation of the antenna and
connection of the same to the Premises and installation of the conduit shall be
made at Tenant's sole cost and expense. Said installation and the effectiveness
of the License shall be subject to (i) Tenant first obtaining all necessary
permits and licenses for installation and operation of the antenna and conduit,
and (ii) Landlord's approval, not to be unreasonably withheld, of the location
and placement of the antenna and the connection of the same to the Premises and
the location, placement and appearance of the conduit. In determining whether to
approve the location and placement of the antenna and conduit, Landlord may
consider a variety of factors related to the size and appearance of the antenna
and conduit and their proposed locations, including, without limitation, the
aesthetic aspects of said antenna and conduit and, in the case of the antenna,
its potential interference with Landlord's enjoyment of the private deck located
on the 12th floor of the Building or the view from the same. As to the conduit,
Tenant covenants to install the same in a professional manner and so as not to
degrade the appearance of the Building. If approved and installed, for purposes
of Tenant's insurance requirements hereunder, the antenna and its adjoining
area, and the conduit, shall be considered part of the Premises.

               d. Construction Noise. Tenant acknowledges that for a period of
time following the Commencement Date, the Landlord may conduct construction of
improvements and remodeling of areas of the Building, and that noise, dust and
other factors related to said construction may interfere with Tenant's full
enjoyment of the Premises, and Tenant hereby consents to said interference,
provide that Tenant is able to conduct its business in a reasonable manner.

               e. Termination of Current Lease. Effective on the Commencement
Date, and subject to Tenant taking possession of the Premises and otherwise
performing under this Lease, the Current Lease shall terminate and Tenant shall
immediately return possession of the Current


                                       2
<PAGE>   6
Premises to Landlord, along with the furniture rented by Tenant pursuant to the
Current Lease, all in accordance with the terms and conditions of the Current
Lease.

               f. Signing Bonus. Upon execution of this Lease, and subject to
Tenant making the payments described in Section 7 hereof, Landlord shall pay
Tenant a Lease signing bonus in the amount of Thirty Thousand Dollars ($30,000).

        2. Initial Term. The Initial Term of this Lease shall begin on the
Commencement Date and shall end on the Expiration Date, unless earlier
terminated pursuant to the provisions hereof or extended pursuant to Section 3,
below. The Initial Term and any extensions thereof shall be referred to
collectively as the "Term."

        3. Option to Extend Term.

               a. Option to Extend. Subject to the provisions of this Section,
Tenant, at Tenant's sole option, may extend the Term for one (1) additional
period(s) of three (3) years (the "Option Period") by giving written notice to
Landlord of its intention to do so no later than ninety (90) days prior to the
Expiration Date. Annual Base Rent for the Option Period shall be determined in
accordance with subsection b., below, and such determination shall be binding
upon all parties

               b. Base Rent During Option Period. The Annual Base Rent for the
first year of the Option Period shall be equal to the fair market value rent for
the Premises as determined by independent appraisal (the "Extension Rent") in
accordance with this subsection. Upon receipt by Landlord of written notice from
Tenant of the exercise of its option to extend, Landlord shall appoint an
independent appraiser for the purpose of determining the Extension Rent. The
appraiser shall complete the appraisal forthwith and shall notify Landlord and
Tenant in writing of the determination of the fair market value rent within
fifteen (15) days after the date of the appointment. If said determination is
disputed, Tenant, at Tenant's sole cost and expense, shall (i) notify Landlord
in writing of such dispute, and (ii) within ten (10) days after the date of said
notice, appoint a second independent appraiser who shall, in turn, conduct an
appraisal and notify Landlord and Tenant in writing of the determination of the
fair market value rent within fifteen (15) days after the date of the
appointment. If the first two appraisers cannot agree on the fair market value
Rent, they shall jointly appoint a third independent appraiser within ten (10)
days after the determination by the second appraiser. The third appraiser shall
then conduct an appraisal and shall notify Landlord and Tenant in writing of the
determination of the fair market value rent within fifteen (15) days after the
date of the appointment. The fair market value rent shall then be the average of
the two closest appraisals. Landlord and Tenant shall share the cost of the
third appraiser.

               c. Qualifications of Appraiser. Any appraiser appointed pursuant
to this Section 3 shall be an MAI-designated appraiser with at least five (5)
years' experience in appraising commercial real property rental values in the
City and County of San Francisco.

               d. Single Appraiser. Nothing contained herein shall prevent
Landlord and Tenant from jointly selecting a single appraiser to determine the
fair market value rent, in which


                                       3
<PAGE>   7
event the determination of the appraiser shall be conclusively deemed the fair
market value rent. Landlord and Tenant shall share equally the fees and expenses
of said joint appraiser.

               e. Extension Rent. Extension Rent, as used in this Section 3,
shall mean only the Annual Base Rent for the Option Period, exclusive of any
Additional Rent, as defined in Section 5, below. In no event shall the Extension
Rent be less than the amount of Annual Base Rent charged during the last year of
the Initial Term.

               f. No Commissions. In no event shall Landlord pay, or become
liable to pay, any commissions or other compensation to Tenant's real estate
brokers involved in Tenant's exercise of its option to extend the term pursuant
to this Section.

        4. Base Rent.

               a. Annual Base Rent. Tenant agrees to pay to Landlord as Annual
Base Rent for the Premises the amount set forth in the Basic Lease Information.
Payment of the Annual Base Rent shall be made in monthly installments, each in
the amount of the Monthly Base Rent (as defined in the Basic Lease Information),
payable in advance on the first day of each calendar month during the Term. If
the Commencement Date is a day other than the first day of a calendar month,
then the rental due hereunder for the first month of the Term shall be prorated
in the proportion that the number of days this Lease is in effect during said
month bears to the number of days in said month. All rental shall be paid to
Landlord without deduction or offset, in lawful money of the United States of
America, at Landlord's Address, or to such other person or persons or at such
other places as Landlord may from time to time designate by written notice to
Tenant.

               b. Late Payment. Tenant hereby acknowledges that late payment of
Annual Base Rent or Additional Rent, as defined in Section 5, below, after the
expiration of seven (7) calendar days after the due date thereof (the "Grace
Period") shall cause Landlord to incur costs not contemplated by this Lease, the
exact amount of which is difficult to ascertain. Said costs include, without
limitation, processing and accounting charges and late charges that may be
imposed on Landlord by any holder of a deed of trust on the Building.
Accordingly, if any installment of Annual Base Rent or Additional Rent due from
Tenant shall not be received by Landlord prior to the expiration of the Grace
Period, Tenant shall pay to Landlord a late charge equal to ten percent (10%) of
such overdue amount. Landlord and Tenant agree that said late charge represents
a fair and reasonable estimate of the costs Landlord will incur by reason of
late payment by Tenant. Acceptance of said late charge by Landlord shall in no
event constitute a waiver of Tenant's default with respect to such overdue
amount, nor prevent Landlord from exercising any of the other rights and
remedies available at law and/or under this Lease.

               c. Interest. Rent not paid when due shall bear interest from the
date due until paid at the rate of ten percent (10%) per annum.

               d. Rent Abatement. Base Rent shall be abated for the last three
(3) months of the Initial Term.


                                       4
<PAGE>   8
        5. Additional Rent.

               a. Direct Expenses. For purposes of this Lease, the following
terms shall have the meanings described below:

                      (1) "Base Year" shall mean the calendar year 1994;

                      (2) "Excess Taxes" with respect to any tax year shall mean
the amount, if any, by which Real Estate Taxes for such Tax year exceed the Real
Estate Taxes for the Base Year;

                      (3) "Excess Expenses" with respect to any Expense Year

Real Estate Taxes shall not include franchise, transfer, inheritance or capital

<PAGE>   10
right initially to determine monthly estimates and to revise such estimates from
time to time. If the actual Excess Taxes or Excess Expenses exceed the estimated
Excess Taxes or Excess Expenses paid by the Tenant for such Tax Year or Expense
Year, Tenant shall pay to Landlord the difference between the amount paid by
Tenant and the actual Excess Taxes and Excess Expenses within thirty (30) days
after the receipt of Landlord's Tax and Expense Statement, and if the total
amount paid by Tenant for any such Tax Year or Expense Year exceeds the actual
Excess Taxes or Excess Expenses for such Tax Year or Expense Year, such Excess

Expenses due from Tenant to Landlord.

                      (2) If Tenant wishes to dispute the determination of the
Excess Expenses, Tenant shall give Landlord written notice of dispute within
thirty (30) days after receipt from Landlord of Landlord's Tax and Expense
Statement. If Tenant does not give Landlord a notice of dispute within such
time, Tenant shall have waived its right to dispute such determination or
calculation. Promptly after the giving of such written notice, Landlord shall
meet with Tenant in an attempt to reconcile any outstanding disputes. If such
efforts do not succeed, Landlord shall cause to be made a complete audit of
Landlord's records relating to the matter in dispute by a firm of independent
certified accountants to be selected by Landlord, the costs of such audit to be
borne by Tenant. If such audit reveals that the amount previously determined by
Landlord was incorrect, a correction shall be made and either Landlord shall
promptly return to Tenant any overpayment or Tenant shall promptly pay any
underpayment to Landlord. Notwithstanding the pendency of any dispute hereunder,
Tenant shall make payments based upon Landlord's determination or calculation
until such determination or calculation has been established hereunder to be
incorrect.

               d. Personal Property Taxes. Tenant hereby agrees to pay all taxes
which may be levied with respect to Tenant's personal property located in the
Premises including, without limitation, the portion of the improvements to the
Premises, if any, the cost which was borne by Tenant, and any furniture, office
equipment and other furnishings. Tenant agrees to use its best efforts to cause
such personal property to be taxed or assessed separately from the Premises and
not as a lien thereon.

        6. Right of First Refusal.

               a. Landlord shall notify Tenant in writing upon receipt of any
serious, good faith offer from a third party for rental of all or portion of the
eleventh (11th) floor of the Building (the "Expansion Premises"). Said notice
shall contain the third party's proposed rental rate and all other proposed
terms, as well as Landlord's asking rental rate and all other asking terms.
Tenant shall then have seven (7) calendar days after receipt of said notice to
notify Landlord in writing of Tenant's intention to lease the Expansion Premises
on Landlord's asking terms. If Tenant notifies Landlord that it does not
exercise its right of first refusal hereunder, or fails to notify Landlord
within said seven (7) day period, Landlord shall be free to lease the Expansion
Premises to the third party on terms no less favorable to Landlord than those
asked by Landlord and set forth in Landlord's notice to Tenant.


                                       7
<PAGE>   11
               b. In the event that Tenant exercises its right of first refusal
with respect to the Expansion Premises, Tenant and Landlord shall, as a
condition to the effectiveness of said exercise, execute a new lease agreement
with respect to the Expansion Premises, in form and substance similar to this
Lease, except for the terms and conditions required by this Section. Upon
execution and delivery of said new lease agreement, Landlord and Tenant shall
fully discharge and release each other from their respective obligations under
this Lease.

               7. Security Deposit. Upon execution of this Lease, Tenant shall
(i) pay Landlord an amount equal to Monthly Base Rent for the first (1st) month
of the Term, and (ii) deposit with Landlord the sum specified in the Basic Lease
Information (the "Security Deposit") . The Security Deposit shall be held by
Landlord as security for the faithful performance by Tenant of all of Tenant's
obligations under this Lease. If Tenant fails to pay Rent, or a portion thereof,
or otherwise defaults with respect to any provision of this Lease, Landlord may
use, apply or retain all or any portion of the Security Deposit for the payment
of any Rent in default, for the payment of any other sum to which Landlord may
become obligated by reason of Tenant's default, or to compensate Landlord for
any loss or damage which Landlord may suffer thereby. If Landlord so uses,
applies or retains all or any portion of the Security Deposit, Tenant shall,
within ten (10) days after demand therefor, deliver to Landlord an amount
sufficient to restore the Security Deposit to the full amount set forth in the
Basic Lease Information, and Tenant's failure to do so shall be a material
breach of this Lease. Landlord shall be free to commingle the Security Deposit
with funds held in Landlord's own accounts, including accounts in which Landlord
keeps other security deposits. If Tenant performs all of its obligations under
this Lease, the Security Deposit, or so much thereof as has not been used,
applied or retained by Landlord in accordance with this Section, shall be
returned to Tenant, within thirty (30) days after the expiration of the Term,
and subject to Tenant relinquishing possession of the Premises, without payment
of interest or other increment for its use. No trust relationship is created
herein between Landlord and Tenant with respect to the Security Deposit. In the
event the Building is sold or otherwise transferred, credit for the Security
Deposit shall be transferred by Landlord to the new owner.

        8. Tenant's Improvements. Prior to the Commencement Date, Landlord shall
install for Tenant's use the improvements to the premises described in Exhibit B
to this Lease (the "Tenant's Improvements"). All of the Tenant's Improvements
shall be the property of Landlord upon installation and shall not be removed or
altered by Tenant, except with the prior written consent of Landlord, and
Landlord shall have the right to depreciate and claim deductions against income
with respect to the Tenant's Improvements. Upon expiration or earlier
termination of this Lease, Landlord shall be free to elect whether to retain the
Tenant's Improvement or demolish and remove the same, in whole or in part, at
Tenant's sole cost and expense.

        9. Use and Compliance with Laws. Use of the Premises shall be on the
following terms:

               a. Use. Tenant shall use or permit the Premises to be used only

<PAGE>   12
for any other purposes without obtaining the prior written consent of Landlord,
which consent may be given or withheld in Landlord's sole and absolute
discretion. Tenant shall not use or permit the Premises to be used in any manner
that may result in waste or subject the Premises to any use which would damage
the Premises or raise the cost of or violate any insurance coverage maintained
at the Building or create a nuisance. Tenant shall maintain the Premises free of
any objectionable noise, odors or disturbances. Without limiting the generality
of the foregoing, Tenant shall dispose of waste as follows:

                      (1) Tenant shall not keep any trash, garbage, waste or
other refuse on the Premises except in sanitary containers and shall regularly
and frequently remove the same from the Premises. Tenant shall keep all
containers or other equipment used for the storage or disposal of such matter in
a clean and sanitary condition.

                      (2) Tenant shall properly dispose of all sanitary sewage
and shall not use the sewage disposal system for the disposal of anything except
sanitary sewage. Tenant shall keep the sewage disposal system free of all
obstructions and in good operating condition.

                      (3) Tenant shall properly dispose of all other waste or
other matter stored1 used or located on the Premises in accordance with the
terms set forth in subsection b., below.

               b. Compliance with Laws. Notwithstanding any other provision in
this Lease to the contrary, Tenant, at its sole cost and expense, shall comply
with all laws, statutes, ordinances, regulations, rules, court orders and other
governmental requirements, including all environmental laws and regulations,
whether in effect at the Commencement Date or thereafter, in performing or
observing its obligations under this Lease. Tenant shall not use or permit the
use of the Premises for any purpose or in any manner that may constitute a
violation of the laws of the United States or the laws, ordinances, regulations
or requirements of any governmental entity having authority in the jurisdiction
where the Premises are located. For purposes of this Lease, the phrase
"environmental laws and regulations," or any such similar phrase or term shall
be interpreted in the broadest possible sense, to include any and all laws,
regulations, ordinances and orders enacted, adopted or issued for the protection
of the environment or the public, including, without limitation, the
Comprehensive Environmental Response, Compensation and Liability Act of 1980,

the future). In particular, Tenant shall comply with all laws relating to
storage, use and disposal of toxic materials and hazardous or toxic matter,
including toxic matter described in Title 22 of the California Code of
Regulations ("Toxic Materials"). The provisions of this subsection shall not
supersede, but shall be in addition to, any other provisions of this Lease which
impose a higher standard of care or duty on Tenant.


                                       9
<PAGE>   13
               c. Indemnity. Tenant shall defend, indemnify and hold Landlord
and its agents harmless from any loss, claim, liability, response cost or
expense, including attorneys' fees and costs (including fees and costs on
appeal), arising out of or in connection with Tenant's failure to observe or
comply with the provisions of this Section 10. Tenant shall further be solely
responsible for, and shall defend, indemnify and hold Landlord and its agents
harmless from and against all claims, costs and liabilities, including
attorneys' fees and costs (including fees and costs on appeal) , arising out of
or in connection with the removal, clean-up and restoration work and materials
necessary to return the Premises and any other property of whatever nature and
wherever located to their condition prior to the placing or arrival of any Toxic
Materials on the Premises or use thereof by Tenant. Tenant's obligations
hereunder shall survive the expiration or earlier termination of this Lease.

               d. Toxic Materials. If Tenant does, or intends to, use or
transport any Toxic Materials in any area in or around the Premises or the
Building, Tenant shall give immediate written notice thereof to Landlord, and
Landlord shall have the right to purchase, or require Tenant to purchase,
insurance with coverage of no less than Two Million Dollars ($2,000,000.00) to
insure that any contaminated, polluted or radioactive matter be removed from the
Premises or the Building and that the Premises and the Building are restored to
a clean, neat, attractive, healthy and sanitary condition. If Landlord elects to
purchase said insurance, the cost of the premium therefor shall be paid in full,
as Additional Rent, by Tenant within five (5) days after presentation of an
invoice from Landlord. If Landlord elects to require Tenant to purchase said
insurance, Tenant shall provide satisfactory evidence of such coverage to
Landlord and shall name Landlord as an additional insured on said policy. In the
event that said insurance is unavailable, Tenant shall refrain from using or
transporting any Toxic Material in any area in or around the Premises or the
Building.

               e. Material Default. Any default by Tenant under this Section 10
shall be a material default enabling Landlord to exercise any of the remedies
set forth in this Lease or available at law.

               f. Signs. Other than Tenant's name in the Building's lobby
directory, Tenant shall not install any sign in the Building without the prior
written approval of Landlord, which approval may be withheld in Landlord's
absolute discretion.

               g. Overloading. Tenant shall not place a load upon the floor of
the Premises which exceeds the lesser of (i) the load per square foot which such
floor is designed to carry, or (ii) the load per square foot which is then
allowed by law. No machinery, apparatus, or other appliance shall be used or
operated in or on the Premises if such use or operation will in any manner
injure, vibrate, or shake the Premises.

        10. Maintenance and Repair.

               a. Tenant's Obligations. Tenant shall, at Tenant's sole cost and
expense, keep the Premises and every part thereof in good condition and repair,
reasonable wear and tear excepted. Tenant shall, upon expiration or sooner

a. to the contrary, Landlord shall repair and maintain in good condition the
structural portions of the Building, including the basic plumbing, the heating,
air conditioning and ventilation system, and the electrical system, unless the
need for maintenance or repair of such systems is rendered necessary by the act,
neglect, fault or omission of Tenant, its agents, employees or invitees, in
which case Tenant shall pay to Landlord, as Additional Rent, the cost of such
maintenance or repair. There shall be no abatement of Rent and no liability of
Landlord by reason of any injury or interference with Tenant's business arising
from the making of any repairs, alterations or improvements in or to any portion
of the Building or the Premises or in or to fixtures, appurtenances and
equipment therein. Tenant waives the right to make repairs at Landlord's expense
under Section 1942 of the California Civil Code or under any law, statute or
ordinance now or hereafter in effect.

        11. Alterations.

               a. Landlord's Consent. Tenant shall make no alterations,
decorations, additions or improvements, including changes to the electrical
system or wiring in the Premises (collectively, "Alterations") , in or to the
Premises without Landlord's prior written consent (which consent shall not be
unreasonably withheld); provided, however, that Tenant shall be allowed to
install a lock on the interior stairwell door linking the Premises to the ninth
and eleventh floors of the Building (and shall deliver a key to said door to
Landlord) . Tenant agrees that there shall be no construction, partitions or
other obstructions that might interfere with Landlord's free and safe access to
mechanical installations or service facilities of the Building, or interfere
with the moving of Landlord's equipment to or from the enclosures containing
said installations or facilities. Tenant covenants and agrees that all work done
by Tenant shall be performed in compliance with all laws, rules, orders,
ordinances, directions, regulations and requirements of all governmental
agencies, offices, departments, bureaus and boards having jurisdiction thereof.

               b. Notice. Before commencing any Alterations work, Tenant shall
give Landlord ten (10) days' written notice of the proposed Alterations and
shall secure, at its sole cost and expense, a completion and lien indemnity bond
satisfactory to Landlord for such work. Landlord shall have ten (10) days after
receipt of said notice to approve or disapprove the proposed Alterations. Any
and all Alterations shall, unless Landlord elects otherwise, become the property
of Landlord and shall remain upon, and be surrendered with, the Premises upon
expiration or earlier termination of this Lease. Landlord may, by written notice
to Tenant given at least sixty (60) days prior to the end of the Initial Term,
require Tenant to remove at Tenant's sole cost and expense all Alterations and
repair any damage resulting from such removal, provided that Landlord has so
stipulated at the time it approved said Alterations. Notwithstanding anything in
the foregoing to the contrary, Tenant may remove its fixtures,


                                       11
<PAGE>   15
provided that Tenant repairs any damage caused by such removal and that such
removal and repair is completed prior to the expiration or earlier termination
of the Term.

attendant services during the Building's recognized business hours, as set out
in the Building's Rules and Regulations and as modified by Landlord from time to
time in its sole discretion. Tenant shall pay directly to the billing entity for
any utilities separately metered to the Premises, and shall pay Landlord as
Additional Rent for any utilities billed to Landlord and used by Tenant in
excess of normal usage. Tenant further agrees to conduct its business in the
Building in such manner as not to overload the Building's electrical system or
cause any interruption in service. Landlord shall not be liable for, and Tenant
shall not be entitled to any reduction or abatement of Rent by reason of,
Landlord's failure to furnish any of the foregoing utilities when such failure
is due to the utility entity's failure to provide said services, or when such
failure is caused by accident, breakage, repairs, strikes, lockouts or other
labor disturbances or labor disputes of any character, governmental regulation,
moratorium, other governmental action or inaction, or any act of God.

        13. Insurance and Indemnity.

               a. Casualty Insurance. During the Term of this Lease, Tenant
shall, at Tenant's sole cost and expense, obtain and keep in full force and

fixtures installed by Tenant (including Tenant's Improvements), and any other
personal property, in an amount no less than one hundred percent (100%) of the
full replacement value, without deduction for depreciation.

               b. Liability Insurance. During the Term of this Lease, Tenant
shall, at Tenant's sole cost and expense, obtain and keep in full force and
effect comprehensive general liability insurance insuring Tenant against any and
all liability arising out of the lease, use, occupancy or maintenance of the

Dollars ($2,000,000) in the event of personal injury to any number of persons or
of damage to property arising out of any one occurrence. All of such insurance ~
be primary and noncontributing with any insurance which may be carried by
Landlord, shall name Landlord as an additional insured and shall contain a
provision that Landlord, although named as an insured, shall nevertheless be
entitled to recover under the policy for any loss, injury or damage to Landlord,
its agents or employees, or the property of such persons by reason of the
negligence of Tenant. All such insurance shall specifically insure Tenant's
performance of the indemnity obligations contained in subsection e. of this
Section.


                                       12

expiration of each policy, Tenant shall furnish to Landlord a certificate of
insurance issued by the insurance carrier of each policy of insurance carried by
Tenant pursuant to this Lease providing that such policies shall not be
cancelable or subject to reduction of coverage or other modification except
after thirty (30) days' prior written notice to Landlord.

               d. Subrogation. Any policy or policies of fire, extended
coverage, or similar casualty insurance shall, to the extent the same may be
obtained without undue expense, include a clause or endorsement denying the
insurer any rights of subrogation against the other party to the extent rights
have been waived by the insured prior to the occurrence of injury or loss.
Landlord and Tenant waive any rights of recovery against the other for injury or
loss due to hazards covered by insurance containing such a waiver of subrogation
clause or endorsement to the extent of the injury or loss covered thereby.

               e. Indemnification. Tenant shall indemnify, defend and hold
Landlord, the Premises and the Building harmless from and against (i) any and
all liability, penalties, losses, damages, costs and expenses, demands, causes
of action, claims or judgments arising from or growing out of any injury to any
person or persons or damage to any property as a result of any accident or other
occurrence during the Term, occasioned in any way as a result of Tenant's or
Tenant's officers, employees, agents, servants, subtenants, concessionaires,
licensees, contractors or invitees use, maintenance, occupation, or operation of
the Premises during the Term, and (ii) any and all legal costs and charges,
including attorneys' fees, incurred in and about any such matters and the
defense of any action arising out of the same or in discharging the Building or

obligations pursuant to the foregoing indemnity shall survive the expiration or
earlier termination of this Lease.

               a. Obligation to Repair or Rebuild. Except as otherwise provided
in this Section, if the Premises are damaged or destroyed during the Term,
Landlord shall diligently repair or rebuild them to substantially the condition
in which they existed immediately prior to the damage or destruction; provided,
however, that Landlord shall be obligated to repair or rebuild the Premises only
if (i) insurance proceeds are available therefor and such proceeds are not
applied by any lender against payment of an existing loan on the Building or the
land on which the Building is located, and (ii) such repairs or rebuilding can
be accomplished within ninety (90) days, as determined in Landlord's reasonable
judgment.

               b. Abatement of Rent. Rent shall be abated in proportion to the
amount of the Premises that are damaged or destroyed, during any period in
which, by reason of any damage or destruction, Tenant reasonably determines that
there is substantial interference with


                                       13
<PAGE>   17
the operation of Tenant's business in the Premises. Such abatement shall
continue for the period commencing with such damage or destruction and ending
with the earlier of (i) substantial completion by Landlord of the work of repair
or reconstruction which Landlord is obligated or undertakes to do, or (ii)
expiration or earlier termination of this Lease.

               c. Impracticable to Repair or Rebuild; Termination. If the
Premises or the Building are damaged or destroyed to the extent that Landlord
determines that the Premises or Building cannot, with reasonable diligence, be
fully repaired and restored by Landlord within one hundred and eighty (180) days
after the date of the damage or destruction, Landlord and Tenant shall employ
their reasonable good faith efforts to agree, within fifteen (15) days after the
date of the damage o~ destruction, on whether to (i) terminate this Lease, or
(ii) maintain this Lease in full force and effect for a period of time equal to
the time necessary to repair or restore the Premises or the Building plus thirty
(30) days. In the event that no agreement is reached within said fifteen (15)
day period, this Lease shall automatically terminate without further notice.

               d. End of Term. Notwithstanding anything to the contrary
contained in this Lease, if the Premises or the Building are partially destroyed
or damaged during the last twelve (12) months of the Term, Landlord may elect to
terminate this Lease as of the date such destruction or damage occurred, with no
liability to Tenant, by serving on Tenant within thirty (30) days from the date
such destruction or damage occurred, written notice of Landlord's election to
terminate this Lease.

               e. Insurance Coverage. Notwithstanding anything contained herein
to the contrary, in the event of damage to or destruction of all or any portion
of the Premises or the Building which is not fully covered by insurance for the
benefit of Landlord, Landlord may terminate this Lease by written notice to
Tenant, given within forty-five (45) days after the date of notice to Landlord
that said damage or destruction is not so covered.

               f. Waiver. With respect to any damage or destruction which
Landlord is obligated to repair or may elect to repair under the terms of this
Section, Tenant hereby waives all rights to terminate this Lease pursuant to
rights otherwise presently or hereafter accorded by law to tenants.

        15. Condemnation.

               a. Complete Condemnation. If the whole of the Premises is
acquired or condemned by eminent domain, inversely condemned or sold in lieu of
condemnation, for any public or quasi-public use or purpose ("Condemned"), then
this Lease shall terminate as of the date of such condemnation. Each party shall
notify the other promptly of any such occurrence.

               b. Partial Condemnation. If any part of the Premises is partially
Condemned, and such partial condemnation renders the Premises unusable for the
business of Tenant, as reasonably determined by Landlord, or in the event that a
substantial portion of the Building is Condemned, as reasonably determined by
Landlord, then this Lease shall terminate as of the date of title vesting in
such proceeding. If such condemnation is not sufficiently extensive to render


                                       14
<PAGE>   18
the Premises unusable for the business of Tenant, as reasonably determined by
Landlord, or, if less than a substantial portion of the Building is Condemned,
then Landlord shall (to the extent the proceeds of the award are available
therefrom and are not applied by any lender against payment of an existing loan
on the Building or on the land on which the Building is located) promptly
restore the Premises to a condition comparable to their condition immediately
prior to said condemnation, less the portion thereof lost in said condemnation,
and this Lease shall continue in full force and effect, except that the Annual
Base Rent shall be appropriately reduced as reasonably determined by Landlord.

               c. Landlord's Award. If the Premises are wholly or partially
condemned, then, subject to the provisions of subsection d., below, Landlord
shall be entitled to the entire award paid for such condemnation, and Tenant
waives any right or claim to any part thereof from Landlord or the condemning
authority.

               d. Tenant's Award. Tenant shall have the right to claim and
recover from the condemning authority, but not from Landlord, only such
compensation as may be separately awarded or recoverable by Tenant in Tenant's
own right on account of (i) any and all costs or loss to which Tenant might be
put in removing Tenant's merchandise, fixtures, furniture and equipment to a new
location and (ii) any loss of goodwill occasioned to Tenant's business.

               e. Temporary Condemnation. If the whole or any part of the
Premises shall be Condemned for any temporary public or quasi-public use or
purpose, this Lease shall remain in effect and Tenant shall be entitled to
receive for itself such portion or portions of any award made for such use with
respect to the period of the taking that is within the Term. if a temporary
condemnation remains in force at the expiration or earlier termination of this
Lease, Tenant shall pay to Landlord a sum equal to the reasonable cost of
performing any obligations required of Tenant by this Lease with respect to the
surrender of the Premises, including, without limitation, repairs and
maintenance, and upon such payment Tenant shall be excused from any such
obligations. If a temporary condemnation is for an established period which
extends beyond the Term, this Lease shall terminate as of the date of occupancy
by the condemning authority.

               f. Sale under Threat of Condemnation. 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 purposes of this Section 16.

        16.    Assignment and Subletting.

               a. Landlord's Consent. Tenant, including any subsequent assignee
or subtenant, shall not assign, mortgage, pledge or otherwise transfer this
Lease, in whole or in part, nor sublet or permit occupancy by any party other
than Tenant of all or any part of the Premises, without the prior written
consent of Landlord in each instance, which consent shall not be unreasonably
withheld. No permitted assignment or subletting shall relieve Tenant of any
obligation under this Lease, including Tenant's obligation to pay Rent and other
monies due hereunder. Any purported assignment or subletting contrary to the
provisions hereof without Landlord's prior written consent shall be void. The
consent by Landlord to any assignment or


                                       15
<PAGE>   19
subletting shall not constitute a waiver of the necessity for such consent to
any subsequent assignment or subletting.

               b. Instrument in Writing. Any assignment or subletting to which
Landlord has consented shall be by an instrument in writing, in form and
substance satisfactory to Landlord, and any assignee, sublessee, transferee,
licensee, concessionaire or mortgagee shall agree for the benefit of Landlord to
be bound by, assume and perform all the terms, covenants and conditions of this
Lease.

               c. Assignment of Rent If Tenant assigns its interest in this
Lease or sublets the Premises or any portion thereof, Tenant immediately,
unconditionally and irrevocably assigns to Landlord, as security for Tenant's
obligations under this Lease, all rent due Tenant from such assignment or
subletting as permitted under this Lease, and Landlord, as assignee and
attorney-in-fact for Tenant, or a receiver for Tenant appointed on Landlord's
application, may collect such rent and apply it toward Tenant's obligations
under this Lease; except that, until the occurrence of an act of default by
Tenant, Tenant shall have the right to collect such rent.

               d. Bonus Rental. If for any assignment or subletting Tenant
receives rent or other consideration, either initially or over the term of the
assignment or sublease, in excess of the Rent called for hereunder, or, in the
case of a sublease of a portion of the Premises, in excess of such Rent fairly
allocable to such portion, Tenant shall pay to Landlord, as Additional Rent
hereunder, one hundred percent (100%) of the excess of each such payment of rent
or other consideration received by Tenant within three (3) days after receipt.

               e. Costs and Expenses. As Additional Rent hereunder, Tenant shall
pay all of Landlord's costs and expenses, including attorneys' fees, appraisal
fees, and other consultants' fees incurred in connection with the review and
consideration by Landlord of any proposed assignment or subletting, whether or
not Landlord's consent to the assignment or subletting is ultimately given.

        17. Events of Default; Landlord's Remedies.

               a. Events of Default. The occurrence of any of the following
shall constitute a material default by Tenant under this Lease:

                      (1) Failure to pay Rent when due, if the failure continues
for a period of seven (7) calendar days.

                      (2) Vacation or abandonment of the Premises.

                      (3) Default in the performance of any of Tenant's
covenants, agreements or obligations hereunder (other than default in the

days after written notice thereof from Landlord.

                      (4) A general assignment by Tenant for the benefit of
creditors.


                                       16
<PAGE>   20
                      (5) The filing of a voluntary petition by Tenant, or the
filing of an involuntary petition by any of Tenant's creditors, seeking the
rehabilitation, liquidation or reorganization of Tenant under any law relating
to bankruptcy, insolvency or other relief of debtors

                      (6) The appointment of a receiver or other custodian to
take possession of substantially all of Tenant's assets or of this leasehold.

                      (7) Tenant becoming insolvent or unable to pay its debts,
or failing generally to pay its debts as they become due; or any court entering
a decree or order directing the winding up or dissolution of Tenant or the
liquidation of substantially all of its assets; or Tenant taking any action
toward the dissolution or winding up of its affairs or the cessation or
suspension of its use of the Premises.

                      (8) Attachment, execution or other judicial seizure of
substantially all of Tenant's assets or this leasehold.

                      (9) Failure to comply with the provisions of Section 9 of
this Lease.

        b. Landlord's Remedies. In the event of Tenant's default under this
Lease, Landlord shall have the remedies set forth below with respect to said
default. Landlord's remedies shall be cumulative and in addition to any other
remedy permitted by law, and the failure by Landlord to insist upon the strict
performance of any term hereof or to exercise any right or remedy hereunder
shall not constitute a waiver of such right or remedy.

                      (1) If Tenant vacates or abandons the Premises, this Lease
shall continue in effect unless terminated by Landlord and Landlord shall have
all the rights and remedies of a landlord provided by Section 1951.4 of the
California Civil Code.

                      (2) Following the occurrence of any default, Landlord
shall have the right, so long as the default continues, to terminate this Lease

prejudice to any other remedies Landlord may have by reason of Tenant's default,
Landlord may (a) re-enter the Premises upon surrender by Tenant or remove Tenant
and any person occupying the Premises, (b) repossess and enjoy the Premises or
relet the same on such terms and conditions as Landlord, in its sole discretion,
may determine, and (c) remove all personal property from the Premises.

                      (4) Following termination under clause (2), above,
Landlord shall have all the rights and remedies of a landlord under Section
1951.2 of the California Civil Code.

        c. Additional Remedies. In addition to the foregoing remedies, Landlord
shall have the right to remedy any default of Tenant, to maintain or improve the
Premises without terminating this Lease, and to incur expenses on behalf of
Tenant in seeking a subtenant or assignee, including, without limitation,
broker's commissions and attorneys' fees.


                                       17
<PAGE>   21
        18. Landlord's Right of Entry. Landlord, its agents and employees, shall
have the right to enter the Premises at all times in case of emergency, and at
reasonable times upon 24 hours notice for any other purpose, including, without
limitation, the following: (i) to determine whether Tenant is in compliance with
its obligations under this Lease, (ii) to do any necessary maintenance and to
repair or restore the Premises or other portions of the Building, (iii) to post
or serve any notices required or permitted by this Lease, (iv) to post "for
sale" signs at any time during the Term, and to post "for lease" signs at any
time during the last year of the Term, and (v) to show the Premises to
prospective buyers, tenants, brokers, or persons interested in an exchange, at
any time during the Term. Landlord agrees to exercise its right of entry in such
manner as to minimize any inconvenience to Tenant or interference with Tenant's
business. Notwithstanding the foregoing, Landlord shall not be liable in any
manner for any inconvenience, disturbance, loss of business, nuisance or other
damage arising out of Landlord's entry on the Premises in accordance with this
Section.

        19. Subordination: Estoppel.

               a. Subordination. This Lease is and shall be subordinate to any
encumbrance now of record or recorded after the date of this Lease affecting the
Building, other improvements, and the land on which the Building is located.
Such subordination is effective without any further act of Tenant. Tenant shall,
from time to time upon Landlord's request, execute and deliver within ten (10)
days after Landlord's request any documents or instruments that may be required
by a lender to effect such subordination. If Tenant fails to execute and deliver
any such documents or instruments, Tenant hereby irrevocably constitutes and
appoints Landlord as Tenant's special attorney-in-fact to execute and deliver
any such documents or instruments.

               b. Estoppel Certificate. Within ten (10) days after request by
Landlord, or if on any sale, assignment or hypothecation by Landlord of
Landlord's interest in the Building, the land on which the Building is located,
or any portion thereof, an estoppel certificate shall be required, Tenant shall
deliver, substantially in the form attached hereto as Exhibit C, or in such
other form as may be reasonably requested by prospective lenders or purchasers,
an estoppel certificate to any proposed mortgagee, purchaser, sublessee or
assignee and to the Landlord. Failure to deliver said certificate in time shall
constitute a material default under this Lease giving Landlord the option to
terminate this Lease in accordance with Section 18b(2) hereof. Further, failure
to deliver the certificate in time shall be conclusive upon the non-requesting
party that (i) this Lease is in full force and effect, without modification
except as may be represented by the requesting party, (ii) there are no uncured
defaults in the requesting party's performance and the non-requesting party has
no right of offset, counterclaim or deduction against Rent hereunder, and (iii)
no more than one period's Monthly Base Rent has been paid in advance.

        20. Sale of Landlord's Interest. In the event of any sale or transfer by
Landlord of the Premises or the Building, and assignment of this Lease by
Landlord, Landlord shall be and is hereby relieved of any and all liability and
obligations contained in or derived from this Lease arising out of any act,
occurrence or omission relating to the Premises or this Lease occurring after
the consummation of such sale or transfer, provided the purchaser or transferee
shall assume expressly all of the covenants and obligations of Landlord under
this Lease. If any security


                                       18
<PAGE>   22
deposit or prepaid rent has been paid by Tenant, Landlord may transfer the same
to Landlord's successor and, upon such transfer, Landlord shall be relieved of
any and all further liability with respect thereto.

               a. The prevailing party in any dispute with respect to the
meaning or enforceability of this Lease, or the enforcement of any provisions
hereof, whether or not said dispute results in litigation or arbitration, shall
recover from the other party all reasonable costs and expenses, including,
without limitation, reasonable attorneys' fees.

               b. Without limiting the generality of the foregoing, any
reasonable costs and expenses, including, without limitation, reasonable
attorneys' fees, incurred in enforcing any judgment or arbitration award shall
be recoverable by the prevailing party as a separate item of recovery. This
subsection b. is intended to be severable from the other provisions of this
Lease and shall survive any judgment or arbitration award and shall not be
deemed to be merged into the judgment or award.

        26. Notices. Any notice required or contemplated by this Lease shall be
delivered either by (i) personal delivery, (ii) postage prepaid receipt
requested certified mail, or (iii) telecopy or other facsimile transmission,

conditions shall be binding upon and shall inure to the benefit of the parties

Lease.

        33. Severability. If any term, covenant, condition or provision of this
Lease, or the application thereof to any person or circumstance, shall to any
extent be held to be invalid, void or unenforceable, the remainder of the terms,
covenants, conditions or provisions of this Lease shall remain in full force and
effect and shall in no way be affected, impaired or invalidated.

        34. Entire Agreement. This Lease sets forth all covenants, promises,
agreements, conditions and understandings between Landlord and Tenant concerning
the Premises, Building and the land on which the Building is located, and there
are no covenants, promises, agreements, conditions or understandings, either

RE:     March Rent Adjustment

As per our agreement for adjustments of February's rental period. I have
calculated that the difference for the first five days rent amounts to $530.70
(see below for calculations). Since rent for February has already been paid,
therefore, your adjusted rent for March will be $4,769.30.

(based on 29 days in February)

<TABLE>
<S>                                               <C>
5TH FLOOR BASE RENT                               $  2,221.88
        divided by 29 = $76.62 per day
        X 5 days =                                $    383.10

10TH FLOOR BASE RENT                              $  5,300.00
divided by 29 = $182.76 per day
X 5 days =                                        $    913.80

DIFFERENCE -- $913.80 - $383.10 = $  530.70

MARCH RENT -- $ 5,300 - $530.70 = $4,769.30

                                  OFFICE LEASE

        THIS LEASE, dated February 4, 1994, for purposes of reference only, is
made and entered into by and between The Equitable Montgomery Company
("Landlord") and Orrell & Company, Inc. ("Tenant").


                                   WITNESSETH:

        Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord
the premises described in paragraph 1(b) below for the term and subject to the
terms, covenants, agreements and conditions hereinafter set forth, to each and
all which Landlord and Tenant hereby mutually agree.


        1. DEFINITIONS. Unless the context otherwise specifies or requires, the
following terms shall have the meanings herein specified:

               (a) The term "Building" shall mean the land and other real
property described in the Basic Lease Information, as well as any property
interest in the area of the streets bounding the parcel described in the Basic
Lease Information, and all other improvements on or appurtenances to said parcel
or said streets.

               (b) The term "Premises" shall mean the portion of the Building
located on the floor(s) specified in the Basic Lease Information which is
crosshatched on the floor plan(s) attached to this Lease as Exhibit A.

               (c) The term "Base Year" shall mean the calendar year specified
in the Basic Lease Information as the Base Year.

               (d) The term "Operating Expenses" shall mean (1) all costs of
management, operation and maintenance of the Building, including, without
limitation: wages, salaries and payroll of employees; property management fees;
janitorial, maintenance, guard and other services; Building office rent or
rental value; power, water, waste disposal and other utilities; materials and
supplies; maintenance, replacements and repairs; insurance premiums and the
deductible portion of any insured loss; and depreciation on personal property;
and (2) the cost of any capital improvements made to the Building by Landlord
after the Base Year that are reasonably anticipated to reduce other Operating
Expenses or are required for the health and safety of tenants, or made to the
Building by Landlord after the date of this Lease that are required under any
governmental law or regulation that was not in effect as of the date of this
Lease, such cost or allocable portion thereof to be amortized over such
reasonable period as Landlord shall determine together with interest on the
unamortized balance at the rate of 10% per annum or such higher rate as may have
been paid by Landlord on funds borrowed for the purpose of constructing such
capital improvements. Operating Expenses shall not include: Property 



                                       1
<PAGE>   8

Taxes; depreciation on the Building other than depreciation on exterior window
covering provided by Landlord and carpeting in public corridors and common
areas; costs of tenants' improvements; real estate brokers' commissions;
interest (except as stated in clause (2) above); and capital items other than
those referred to in clause (2) above. If less than 95% of the total rentable
area of the Building is occupied during the Base Year or any calendar year
during the term of this Lease, then actual Operating Expenses for such year
shall be adjusted to equal Landlord's reasonable estimate of Operating Expenses
had 95% of the total rentable area of the Building been occupied. Landlord and
Tenant acknowledge that certain of the costs of management, operation and
maintenance of the Building and certain of the costs of the capital improvements
referred to in clause (2) above may be allocated exclusively to a single
component of the Building (e.g., to an office area, a retail area or a parking
facility) and certain of such costs may be allocated among such components. The
determination of such costs and their allocation shall be in accordance with
generally accepted accounting principles applied on a consistent basis. All
operating expense calculations shall be determined in accordance with generally
accepted accounting principles applied on a consistent basis. All operating
expense calculations shall be determined in accordance with GAAP.

               (e) The term "Base Operating Expenses" shall mean the Operating
Expenses paid or incurred by Landlord in the Base Year.

               (f) The term "Property Taxes" shall mean all real property taxes
and assessments (and any tax levied against the Building or the rents earned in
connection with the Building wholly or partly in lieu thereof) levied against
the Building, and all real estate tax consultant expenses and attorneys' fees
incurred for the purpose of maintaining an equitable assessed valuation of the
Building.(1)

               (g) The term "Base Property Taxes" shall mean the amount of
Property Taxes paid by Landlord allocable to the Base Year.

               (h) The term "Tenant's percentage share" shall mean the
percentage figure specified in the Basic Lease Information.

        2. TERM; CONDITION OF PREMISES. The term of this Lease shall commence
and, unless sooner terminated as hereinafter provided, shall end on the dates
respectively specified in the Basic Lease Information. Unless otherwise agreed
by Landlord and Tenant in this Lease, Landlord shall deliver the Premises to
Tenant on March 15, 1994 or upon substantial completion. If Landlord has
undertaken in this Lease to make any alterations to the Premises prior to
commencement of the term and the alterations are completed prior to the date set
forth in the Basic Lease Information for commencement of the term, if Tenant
desires to take occupancy in 

- --------

  (1) Property taxes shall not include interest on taxes or penalties resulting
      from Landlord's failure to pay taxes.

                                       2
<PAGE>   9


advance of such date and Landlord consents to such prior occupancy, Landlord
shall deliver the Premises to Tenant on such advance date as shall be mutually
approved by Landlord and Tenant and, notwithstanding anything to the contrary
contained herein, the term of the Lease shall commence upon such delivery. If
Landlord, for any reason whatsoever, cannot deliver the Premises to Tenant at
the commencement of the term, this Lease shall not be void or voidable, nor
shall Landlord be liable to Tenant for any loss or damage resulting therefrom,
but in that event rental shall be waived for the period between the commencement
of the term and the time when Landlord delivers the Premises to Tenant. No delay
in delivery of the Premises shall operate to extend the term hereof.


        3.  RENTAL.

               (a) Tenant shall pay to Landlord throughout the term of this
Lease as rental for the Premises the sum specified in the Basic Lease
Information as the Base Rent, provided that the rental payable during each
calendar year subsequent to the Base Year shall be the Base Rent, increased by
Tenant's percentage share of the total dollar increase, if any, in Operating
Expenses paid or incurred by Landlord in such year over the Base Operating
Expenses, and also increased by Tenant's percentage share of the total dollar
increase, if any, in Property Taxes paid by Landlord in such year over the Base
Property Taxes. Tenant acknowledges that the Basic Lease Information may set
forth different percentage shares of Operating Expenses and Property Taxes or a
single percentage share applicable to both. The increased rental due pursuant to
this paragraph (a) is hereinafter referred to as "Escalation Rent."

               (b) Rental shall be paid to Landlord on or before the first day
of the term hereof and on or before the first day of each and every successive
calendar month thereafter during the term hereof. In the event the term of this
Lease commences on a day other than the first day of a calendar month or ends on
a day other than the last day of a calendar month, the monthly rental for the
first and last fractional months of the term hereof shall be appropriately
prorated.

               (c) All sums of money due from Tenant hereunder not specifically
characterized as rental shall constitute additional rent, and if any such sum is
not paid when due it shall nonetheless be collectible as additional rent with
the next installment of rental thereafter falling due, but nothing contained
herein shall be deemed to suspend or delay the payment of any sum of money at
the time it becomes due and payable hereunder, or to limit any other remedy of
Landlord.

               (d) Tenant hereby acknowledges that late payment by Tenant to
Landlord of rent and other sums due hereunder after the expiration of any
applicable grace period described in Paragraph 19(a) will cause Landlord to
incur costs not contemplated by this Lease, the exact amount of which will be
difficult to ascertain. Such costs include, but are not limited to, processing
and accounting charges, and late charges which may be imposed on Landlord by the
terms of any encumbrances covering the Building and the Premises. Accordingly,
if any installment of rent or any other sums due from Tenant shall not be
received by Landlord prior to the expiration of any applicable grace period
described in Paragraph 19(a), Tenant shall pay to Landlord a late charge equal
to 2% of such overdue amount. The parties hereby agree that such 




                                       3
<PAGE>   10

late charge represents a fair and reasonable estimate of the costs Landlord will
incur by reason of late payment by Tenant. Acceptance of such late charge by
Landlord shall in no event constitute a waiver of Tenant's default with respect
to such overdue amount, nor prevent Landlord from exercising any of the other
rights and remedies granted hereunder.

               (e) Any amount due from Tenant, if not paid when first due
following the expiration of any grace period provided for, if any, hereunder
shall bear interest from the date due until paid at an annual rate equal to 4%
over the annual prime rate of interest announced publicly by Citibank, N.A., in
New York, New York from time to time (but in no event in excess of the maximum
rate of interest permitted by law), provided that interest shall not be payable
on late charges incurred by Tenant nor on any amounts upon which late charges
are paid by Tenant to the extent such interest would cause the total interest to
be in excess of that legally permitted. Payment of interest shall not excuse or
cure any default hereunder by Tenant.

               (f) All payments due from Tenant shall be paid to Landlord,
without deduction or offset, in lawful money of the United States of America at
Landlord's address for notices hereunder, or to such other person or at such
other place as Landlord may from time to time designate by notice to Tenant.

        4.  ESCALATION RENT PAYMENTS.

               (a) With respect to each calendar year during the term of this
Lease subsequent to the Base Year, Tenant shall pay to Landlord as additional
rent, at the times hereinafter set forth, an amount equal to the Escalation
Rent. Prior to or anytime after the commencement of any calendar year subsequent
to the Base Year Landlord may, but shall not be required to, notify Tenant of
Landlord's estimate of the amount, if any, of the Escalation Rent for such
current year. Tenant shall pay to Landlord on the first day of each calendar
month during such current calendar year one-twelfth (1/12) of the amount of any
such estimated Escalation Rent for such current calendar year payable by Tenant
hereunder. If at any time or times Landlord determines that the amount of any
Escalation Rent payable by Tenant for the current year will vary from its
estimate by more than 5%, Landlord may, by notice to Tenant, revise Landlord's
estimate for such year, and subsequent payments by Tenant for such year shall be
based on such revised estimate. Following the close of each calendar year,
Landlord shall deliver to Tenant a statement of the actual amount of Escalation
Rent for the immediately preceding year, accompanied by a statement made by an
accounting or auditing officer designated by Landlord showing the Operating
Expenses and Property Taxes on the basis of which Escalation Rent was
determined. The statement of said accounting or auditing officer shall be final
and binding upon Landlord and Tenant. All amounts payable by Tenant as shown on
said statement, less any amounts theretofore paid by Tenant on account of
Landlord's earlier estimate of Escalation Rent for such calendar year made
pursuant to this paragraph 4, shall be paid by or, if Tenant theretofore shall
have paid more than such amounts, reimbursed to Tenant within ten (10) days
after delivery of said statement to Tenant.

               (b) If this Lease shall terminate on a day other than the last
day of a calendar year, the amount of any Escalation Rent payable by Tenant for
the calendar year in which the Lease 




                                       4
<PAGE>   11

terminates shall be prorated on the basis by which the number of days from the
commencement of said calendar year to and including said date on which this
Lease terminates bears to 365 and shall be due and payable when rendered
notwithstanding termination of this Lease. Escalation Rent allocable to the
calendar year in which this Lease terminates shall be deemed to have been
incurred evenly over the entire twelve-month period of that calendar year.

        5. USE. The Premises shall be used for general office purposes and no
other. Tenant shall not do or permit to be done in or about the Premises, nor
bring or keep or permit to be brought or kept therein, anything which is
prohibited by or would in any way conflict with any law, statute, ordinance or
governmental rule or regulation now in force or which may hereafter be enacted
or promulgated, or which is prohibited by the standard form of fire insurance
policy, or would in any way increase the existing rate of or affect any fire or
other insurance upon the Building or any of its contents, or cause a
cancellation of any insurance policy covering the Building or any part thereof
or any of its contents. Tenant shall not do or permit anything to be done in or
about the Premises which would in any way obstruct or interfere with the rights
of other tenants of the Building, or injure or annoy them, or use or allow the
Premises to be used for any improper, immoral, unlawful or objectionable
purposes, nor shall Tenant cause, maintain or permit any nuisance or waste in,
on or about the Premises.

        6.  SERVICES.

               (a) Landlord shall maintain the public and common areas of the
Building, including lobbies, stairs, elevators, corridors and restrooms,
windows, mechanical, plumbing and electrical equipment, and the structure itself
in reasonably good order and condition except for damage occasioned by the act
of Tenant, its employees, agents, contractors or invitees, which damage shall be
repaired by Landlord at Tenant's expense.

               (b) Landlord shall furnish the Premises with (1) electricity for
lighting and the operation of customary office machines, (2) heat and air
conditioning to the extent reasonably required for the comfortable occupancy by
Tenant in its use of the Premises during the period from 8 a.m. to 6 p.m. on
weekdays (except holidays), or such shorter periods as may be prescribed by any
applicable policies or regulations adopted by any utility or governmental
agency, (3) elevator service, (4) lighting replacement (for building standard
lights), (5) restroom supplies, (6) window washing with reasonable frequency,
and (7) security guards and services and daily janitor service during the times
and in the manner that such services are customarily furnished in comparable
office buildings in the area. Landlord may establish reasonable measures to
conserve energy, including but not limited to, automatic switching of lights
after hours, so long as such measures do not unreasonably interfere with
Tenant's use of the Premises. Landlord shall not be in default hereunder or be
liable for any damages directly or indirectly resulting from, nor shall the
rental herein reserved be abated by reason of (i) the installation, use or
interruption of use of any equipment in connection with the furnishing of any of
the foregoing services, (ii) failure to furnish or delay in furnishing any such
services when such failure or delay is caused by accident or any condition
beyond the reasonable control of Landlord or by the making of necessary repairs
or improvements to the Premises or to the Building, or (iii) the limitation,
curtailment, rationing or restrictions on use of water, electricity, gas or any
other form 



                                       5
<PAGE>   12

of energy serving the Premises or the Building. Landlord shall use reasonable
efforts diligently to remedy any interruption in the furnishing of such
services.

               (c) Whenever heat-generating equipment or lighting other than
building standard lights are used in the Premises by Tenant which affect the
temperature otherwise maintained by the air conditioning system, Landlord shall
have the right, after notice to Tenant, to install supplementary air
conditioning facilities in the Premises or otherwise modify the ventilating and
air conditioning system serving the Premises, and the cost of such facilities
and modifications shall be borne by Tenant. Tenant shall also pay the cost of
providing all cooling energy to the Premises in excess of that required for
normal office use or during hours requested by Tenant when air conditioning is
not otherwise furnished by Landlord. If there is installed in the Premises
lighting requiring power in excess of that required for normal office use in the
Building or if there is installed in the Premises equipment requiring power in
excess of that required for normal desk-top office equipment or normal copying
equipment. Tenant shall pay for the cost of such excess power, together with the
cost of installing any additional risers or other facilities that may be
necessary to furnish such excess power to the Premises.

               (d) In the event that Landlord, at Tenant's request, provides
services to Tenant that are not otherwise provided for in this Lease. Tenant
shall pay Landlord's reasonable charges for such services upon billing therefor.

        7. IMPOSITIONS PAYABLE BY LESSEE. In addition to the monthly rental and
other charges to be paid by Tenant hereunder, Tenant shall pay or reimburse
Landlord for any and all of the following items thereinafter collectively
referred to as "Impositions"), whether or not now customary or in the
contemplation of the parties hereto taxes (other than local, state and federal
personal or corporate income taxes measured by the net income of Landlord from
all sources), assessments (including, without limitation, all assessments for
public improvements, services or benefits, irrespective of when commenced or
completed), excises, levies, business taxes, license, permit, inspection and
other authorization fees, transit development fees, assessments or charges for
housing funds, service payments in lieu of taxes and any other fees or charges
of any kind, which are levied, assessed, confirmed or imposed by any public
authority, but only to the extent the Impositions are (a) upon, measured by or
reasonably attributable to the cost value of Tenant's equipment, furniture,
fixtures and other personal property located in the Premises, or the cost or
value of any leasehold improvements made in or to the Premises by or for Tenant,
regardless of whether title to such improvements shall be in Tenant or Landlord;
(b) upon or measured by the monthly rental or other charges payable hereunder,
including, without limitation, any gross receipts tax levied by the City and
County of San Francisco, the State of California, the Federal Government or any
other governmental body with respect to the receipt of such rental; (c) upon,
with respect to or by reason of the development, possession, leasing, operation,
management, maintenance, alteration, repair, use or occupancy by Tenant of the
Premises or any portion thereof; or (d) upon this transaction or any document to
which Tenant is a party creating or transferring an interest or an estate in the
Premises. In the event that it shall not be lawful for Tenant to reimburse
Landlord for the Impositions but it is lawful to increase the monthly rental to
take into account Landlord's payment of the Impositions, the monthly rental
payable to  



                                       6
<PAGE>   13

Landlord shall be revised to net Landlord the same net return without
reimbursement of the Impositions as would have been received by Landlord with
reimbursement of the Impositions.

        8.  ALTERATIONS.

               (a) Tenant shall make no alterations, additions or improvements
to the Premises or install fixtures in the Premises without first obtaining
Landlord's consent, which consent shall not be unreasonably withheld. In no
event, however, may the Tenant make any alterations, additions or improvements
or install fixtures which in Landlord's reasonable judgment might adversely
affect the structural components of the Building or Building mechanical, utility
or life safety systems. At the time such consent is requested, Tenant shall
furnish to Landlord a description of the proposed work, an estimate of the cost
thereof and such information as shall reasonably be requested by Landlord
substantiating Tenant's ability to pay for such work. Landlord, at its sole
option, may require as a condition to the granting of such consent to any work
costing in excess of $10,000, that Tenant provide to Landlord, at Tenant's sole
cost and expense, a lien and completion bond in an amount equal to one and
one-half (1 1/2) times any and all estimated costs of the proposed work, to
insure Landlord against any liability for mechanics' and materialmen's liens and
to insure completion of the work. Before commencing any work, Tenant shall give
Landlord at least five (5) days written notice of the proposed commencement of
such work in order to give Landlord an opportunity to prepare, post and record
such notice as may be permitted by law to protect Landlord's interest in the
Premises and the Building from mechanics' and materialmen's liens. Within a
reasonable period following completion of any work for which plans and
specifications were required to obtain a building permit for such work, Tenant
shall furnish to Landlord "as built" plans showing the changes made to the
Premises.

               (b) Any alterations, additions or improvements to the Premises
shall be made by Tenant at Tenant's sole cost and expense, and any contractor or
other person selected by Tenant to make the same shall be subject to Landlord's
prior approval, which approval shall not be unreasonably withheld Tenant's
contractor and its subcontractors shall employ union labor to the extent
necessary to insure, so far as may be possible, the progress of the alterations,
additions or improvements and the performance of any other work or the provision
of any services in the Building without interruption on account of strikes, work
stoppage or similar causes of delay. All work performed by Tenant shall comply
with the laws, rules, orders, directions, regulations and requirements of all
governmental entities having jurisdiction over such work and shall comply with
the rules, orders, directions, regulations and requirements of any nationally
recognized board of insurance underwriters. All alterations, additions and
improvements shall immediately become Landlord's property and, at the end of the
term hereof, shall remain on the Premises without compensation to Tenant;
provided, however, that if Landlord at the time of consenting to the making of
such alterations, additions and improvements reserved the right to have Tenant
remove such alterations, additions and improvements, Tenant shall, prior to the
end of the term, at its sole cost and expense, remove the alterations, additions
and improvements and repair and restore the Premises to their condition at the
commencement of the term. Notwithstanding the foregoing, Tenant shall not be
required to remove any improvements installed by other parties prior to the
commencement of the term.



                                       7
<PAGE>   14

               (c) Tenant acknowledges that there may be asbestos-containing
fireproofing material in the Building and on the Premises. Upon request by
Tenant, Landlord shall provide Tenant with all material information then in
Landlord's possession regarding such fireproofing material. No work affecting
such fireproofing material shall be made without compliance with all applicable
procedures, including procedures promulgated by Landlord, relating to work
involving material containing asbestos.

        9. LIENS. Tenants shall keep the Premises and the Building free from any
liens arising out of any work performed, materials furnished or obligations
incurred by Tenant. Landlord shall have the right to post and keep posted on the
Premises any notices that may be provided by law or which Landlord may deem to
be proper for the protection of Landlord, the Premises and the Building from
such liens.

        10. REPAIRS. By entry hereunder, Tenant accepts the Premises as being in
the condition in which Landlord is obligated to deliver the Premises, provided
that such acceptance shall not extend to latent defects which are not
discoverable through a diligent inspection of the Premises. Tenant shall, at all
times during the term hereof and at Tenant's sole cost and expense, keep the
Premises in good condition and repair, ordinary wear and tear and damage thereto
by fire, earthquake, act of God or the elements excepted. Tenant hereby waives
all rights to make repairs at the expense of Landlord or in lieu thereof to
vacate the Premises. Tenant shall at the end of the term hereof surrender to
Landlord the Premises and all Alterations thereto in the same condition as when
received, ordinary wear and tear and damage by fire, earthquake, act of God or
the elements excepted. Landlord had no obligation and has made no promise to
alter, remodel, improve, repair, decorate or paint the Premises or any part
thereof, except as specifically herein set forth. No representations respecting
the condition of the Premises or the Building have been made by Landlord to
Tenant, except as specifically herein set forth. Landlord agrees to repair and
maintain the structural components of the Building, including but not limited to
the foundation, bearing and exterior walls, sub-flooring and roof, as well as
the elevators, the electrical, mechanical, plumbing, sewage, heating,
ventilating and air conditioning systems, the Common Areas. Tenant shall be
responsible for the repair and maintenance of any supplemental air conditioning
equipment installed by Tenant or Tenant's contractor within the Premises. Tenant
shall provide Landlord a copy of the maintenance agreement for such equipment
within thirty (30) days of such installation.

        Landlord shall use reasonable efforts to enforce construction
warranties' obtained from the initial tenant improvements to the Premises.

        11.  DESTRUCTION OR DAMAGE.

               (a) In the event the Premises or the portion of the Building
necessary for Tenant's use and enjoyment of the Premises are damaged by fire,
earthquake, act of God, the elements or other casualty, Landlord shall repair
the same, subject to the provisions of this paragraph hereinafter set forth, if
(i) such repairs can, in Landlord's opinion, be made within a period of 120 days
after commencement of the repair work, (ii) the cost of repairing damage for
which Landlord is not insured shall be less than ten percent (10%) of the then
full insurable value of the 



                                       8
<PAGE>   15

Premises with respect to repairing any damage to the Premises or five percent
(5%) of the then full insurable value of the Building with respect to repairing
any damage to other areas of the Building, and (iii) the damage or destruction
does not occur during the last twelve (12) months of the term of this Lease or
any extension thereof. This Lease shall remain in full force and effect except
that so long as the damage or destruction is not caused by the fault or
negligence of Tenant, its contractors, agents, employees or invitees, an
abatement of rental shall be allowed Tenant for such part of the Premises as
shall be rendered unusable by Tenant in the conduct of its business during the
time such part is so unusable.

               (b) As soon as is reasonably possible following the occurrence of
any damage, Landlord shall notify Tenant of the estimated time and cost required
for the repair or restoration of the Premises or the portion of the Building
necessary for Tenant's occupancy. If, in Landlord's opinion, such repairs cannot
be made within 120 days as set forth in paragraph (a)(i) above. Landlord or
Tenant may elect by written notice to the other within 30 days after Landlord's
notice of estimated time and cost is given, to terminate this Lease effective as
of the date of such damage or destruction. If Landlord is not obligated to
effect the repair based upon the circumstances set forth in paragraphs (a)(ii)
or (a)(iii) above. Landlord shall have the right to terminate this Lease, by
written notice to Tenant within 30 days after Landlord's notice of time and cost
is given, effective as of the date of such damage or destruction. If neither
party so elects to terminate this Lease, this Lease shall continue in full force
and effect, but the rent shall be partially abated as hereinabove in this
paragraph provided, and Landlord shall proceed diligently to repair such damage.

               (c) A total destruction of the Building shall automatically
terminate this Lease. Tenant waives California Civil Code Sections 1932(2) and
1933(4) providing for termination of hiring upon destruction of the thing hired.

               (d) In no event shall Tenant be entitled to any compensation or
damages from Landlord, specifically including, but not limited to, any
compensation or damages for (i) loss of the use of the whole or any part of the
Premises, (ii) damage to Tenant's personal property in or improvements to the
Premises, or (iii) any inconvenience, annoyance or expense occasioned by such
damage or repair (including moving expenses and the expense of establishing and
maintaining any temporary facilities).

               (e) Landlord, in repairing the Premises, shall not be required to
repair any injury or damage to the personal property of Tenant, or to make any
repairs to or replacement of any alterations, additions, improvements or
fixtures installed on the Premises by or for Tenant.

        12.  INSURANCE.

               (a) Tenant agrees to procure and maintain in force during the
term hereof, at Tenant's sole cost and expense, (i) personal injury liability
insurance with limits of not less than $1,000,000 per person and $1,000,000 per
occurrence for injuries to or death of persons occurring in, on or about the
Premises or the Building, and (ii) property damage liability insurance with a
limit of not less than $1,000,000 per accident. All such insurance policies
shall name Landlord, Landlord's managing agent and any other party designated by
Landlord as 



                                       9
<PAGE>   16

additional insureds; shall insure the performance by Tenant of its indemnity
obligations set forth in paragraph 14 of this Lease; shall insure Landlord's and
Landlord's managing agent's contingent liability as respects acts or omissions
of Tenant; shall be issued by insurance companies licensed to do business in the
State of California and otherwise reasonably acceptable to Landlord; and shall
provide that such insurance may not be cancelled nor amended without thirty (30)
days prior written notice to Landlord. Tenant may carry said insurance under a
blanket policy, provided however, said insurance by Tenant shall include an
endorsement confirming application to and coverage of Landlord.

               (b) A copy of each policy of insurance shall be delivered to
Landlord by Tenant prior to commencement of the term of this Lease and upon each
renewal of such insurance.

               (c) Tenant shall, prior to and throughout the term of this Lease,
procure from each of its insurers under all policies of fire, theft, public
liability, workers' compensation and any other insurance policies of Tenant now
or hereafter existing, pertaining in any way to the Premises or the Building or
any operation therein, a waiver, as set forth in paragraph 13 of this Lease, of
all rights of subrogation which the insurer might otherwise, if at all, have
against Landlord or any officer, agent or employee of Landlord (including
Landlord's managing agent).

               (d) Throughout the term of the Lease and any extension thereof,
Landlord shall maintain all risk and liability insurance in amounts and with
such deductibles as other comparable buildings in the San Francisco Financial
District.

        13. SUBROGATION. Landlord and Tenant shall each obtain from its
respective insurers under all policies of fire, theft, public liability,
workers' compensation and other insurance maintained by either of them at any
time during the term hereof insuring or covering the Building or any portion
thereof or operations therein, a waiver of all rights of subrogation which the
insurer of one party might have against the other party, and Landlord and Tenant
shall each indemnify the other against and reimburse the other for any and all
loss or expense, including reasonable attorneys' fees, resulting from the
failure to obtain such waiver.

        14. INDEMNIFICATION. Tenant hereby waives all claims against Landlord
for damage to any property or injury or death of any person in, upon or about
the Premises arising at any time and from any cause other than principally by
reason of gross negligence or will act of Landlord, its employees or
contractors, and Tenant shall hold Landlord harmless from and reimburse Landlord
for any and all damage to any property or injury to or death of any person
arising from the use or occupancy of the Premises by Tenant or Tenant's failure
to perform its obligations under this Lease, except such as is caused
principally by gross negligence or willful act of Landlord, its contractors or
employees. The foregoing indemnity obligation of Tenant shall include reasonable
attorneys' fees, investigation costs and all other reasonable costs and expenses
incurred by Landlord from the first notice that injury, death or damage has
occurred or that any claim or demand is to be made or may be made. The
provisions of this paragraph shall survive the termination of this Lease with
respect to any damage, injury or death occurring prior to such termination.



                                       10
<PAGE>   17

        15. COMPLIANCE WITH LEGAL REQUIREMENTS. Tenant, at its sole cost and
expense, shall promptly comply with all laws, statutes, ordinances and
governmental rules, regulations or requirements now in force or which may
hereafter be in force, with the requirements of any board of fire underwriters
or other similar body now or hereafter constituted, with any direction or
occupancy certificate issued pursuant to any law by any public officer or
officers, as well as the provisions of all recorded documents affecting the
Premises (including, without limitation, any ground lease, mortgage or
covenants, conditions and restrictions), insofar as any thereof relate to or
affect the condition, use or occupancy of the Premises, including structural
utility system and life safety system changes necessitated by Tenant's acts, use
of the Premises or by improvements made by or for Tenant.

        16.  ASSIGNMENT AND SUBLETTING.

               (a) Tenant shall not, without the prior consent of Landlord,
which consent shall not be unreasonably withheld by Landlord, transfer, assign
or hypothecate this Lease or any interest herein, sublet the Premises or any
part thereof, or permit the use of the Premises by any party other than Tenant.
This Lease shall not, nor shall any interest herein, be assignable as to the
interest of Tenant by operation of law without the consent of Landlord, which
consent shall not be unreasonably withheld. Any of the foregoing acts without
such consent shall be void and shall, at the option of Landlord, terminate this
Lease. In connection with each consent requested by Tenant, Tenant shall submit
to Landlord the terms of the proposed transaction, the identity of the parties
to the transaction, the proposed documentation for the transaction, and all
other information reasonably requested by Landlord concerning the proposed
transaction and the parties involved.

               (b) If the Tenant is a privately held corporation, or is an
unincorporated association or partnership, the transfer, assignment, or
hypothecation of any stock or interest in such corporation, association, or
partnership in excess of fifty percent (50%) in the aggregate shall be deemed an
assignment or transfer within the meaning and provisions of this paragraph 16.
If Tenant is a publicly held corporation, the public trading of stock in Tenant
shall not be deemed an assignment or transfer within the meaning of this
paragraph.

               (c) Without limiting the other instances in which it may be
reasonable for Landlord to withhold its consent to an assignment or subletting,
Landlord and Tenant acknowledge that it shall be reasonable for Landlord to
withhold its consent in the following instances:

                      (1) if at the time consent is requested or at any time 
prior to the granting of consent, Tenant is in default under this Lease or would
be in default under this Lease but for the pendency of any grace or cure period
under paragraph 19 below;

                      (2) if the proposed assignee or sublessee is a
governmental agency;

                      (3) if, in Landlord's reasonable judgment, the use of the
Premises by the Proposed assignee or sublessee would not be comparable to the
types of office use by other tenants in the Building, would entail any
alterations which would lessen the value of the 




                                       11
<PAGE>   18

leasehold improvements in the Premises, would result in more than a reasonable
number of occupants per floor, would require increased services by Landlord or
would conflict with any so-called "exclusive" or percentage leases then in favor
of another tenant of the Building;

                      (4) if, in Landlord's reasonable judgment, the financial
worth of the proposed assignee or sublessee does not meet the credit standards
applied by Landlord for other tenants under leases with comparable terms, or the
character, reputation, or business of the proposed assignee or sublessee is not
consistent with the quality of the other tenancies in the Building;

                      (5) if the subletting would result in the division of the
Premises into three or more units; and

                      (6) if the proposed assignee or sublessee is an existing
tenant of the Building.

               (d) If at any time during the term of this Lease Tenant desires
to assign its interest in this Lease or sublet all or part of the Premises,
Tenant shall give notice to Landlord setting forth the terms of the proposed
assignment or subletting ("Tenant's Notice"). Landlord shall have the option,
exercisable by notice given to Tenant within thirty (30) days after Tenant's
Notice is given (Landlord's Option Period"), either (1) to consent to the
assignment in which event the provisions of paragraph (g) shall be applicable,
or to consent to the subletting in which event the provisions of paragraph (h)
shall be applicable; (2) to become the assignee or sublessee of Tenant (instead
of the entity specified in Tenant's Notice) upon the terms set forth in Tenant's
Notice; (3) in the event of a proposed assignment, to terminate this Lease and
to retake possession of the Premises; or (4) in the event of a proposed
subletting of the entire Premises, or a portion of the Premises for all or
substantially all of the remainder of the term, to terminate this Lease with
respect to, and to retake possession of, such space, together with, if only a
portion of the Premises is involved, such rights of access to and from such
portion as may be reasonably required for its use and enjoyment. If Landlord
does not exercise one of such options, Tenant shall be free for a period of 120
days after Landlord's Option Period, to assign its entire interest in this Lease
or to sublet such space to the entity specified in Tenant's Notice upon the
terms set forth therein or to any third party upon the same terms set forth in
Tenant's Notice, subject to obtaining Landlord's prior consent as hereinabove
provided.

               (e) Notwithstanding the provisions of paragraphs (a) and (b)
above, Tenant may assign this Lease or sublet the Premises or any portion
thereof, with prior notice to Landlord but without the necessity of Landlord's
consent and without extending any option to Landlord pursuant to paragraph (d)
above, to any corporation which controls, is controlled by or is under common
control with Tenant, to any corporation resulting from the merger or
consolidation with Tenant, or to any person or entity which acquires all the
assets of Tenant as a going concern of the business that is being conducted on
the Premises.

               (f) No sublessee (other than Landlord if it exercises its option
pursuant to paragraph (d) above) shall have a right further to sublet without
Landlord's prior consent, which Tenant acknowledges may be withheld in
Landlord's absolute discretion, and any assignment by 



                                       12
<PAGE>   19

a sublessee of its sublease shall be subject to Landlord's prior consent in the
same manner as if Tenant were entering into a new sublease. No sublease, once
consented to by Landlord, shall be modified or terminated by Tenant without
Landlord's prior consent, which consent shall not be unreasonably withheld.

               (g) In the case of an assignment to an entity other than
Landlord, 50% of any sums or other economic consideration received by Tenant as
a result of such assignment shall be paid to Landlord after first deducting the
unamortized cost of leasehold improvements paid for by Tenant, and the cost of
any real estate commissions or legal fees not to exceed $1,500 incurred by
Tenant in connection with such assignment.

               (h) In the case of a subletting to an entity other than Landlord,
50% of any sums or economic consideration received by Tenant as a result of such
subletting shall be paid to Landlord after first deducting (1) the rental due
hereunder, prorated to reflect only rental allocable to the sublet portion of
the Premises, (2) the cost of leasehold improvements made to the sublet portion
of the Premises at Tenant's cost, amortized over the term of this Lease except
for leasehold improvements made for the specific benefit of the sublessee, which
shall be amortized over the term of the sublease, and (3) the cost of any real
estate commissions or legal fees not to exceed $1,500 incurred by Tenant in
connection with such subletting, amortized over the term of the sublease.

               (i) Regardless of Landlord's consent, no subletting or assignment
shall release Tenant of Tenant's obligation or alter the primary liability of
Tenant to pay the rental and to perform all other obligations to be performed by
Tenant hereunder. The acceptance of rental by Landlord from any other person
shall not be deemed to be a waiver by Landlord of any provision hereof. Consent
to one assignment or subletting shall not be deemed consent to any subsequent
assignment or subletting. In the event of default by an assignee of Tenant or
any successor of Tenant in the performance of any of the terms hereof, Landlord
may proceed directly against Tenant without the necessity of exhausting remedies
against such assignee or successor. Landlord may consent to subsequent
assignments or subletting of this Lease or amendments or modifications to this
Lease with assignees of Tenant, without notifying Tenant, or any successor of
Tenant, and without obtaining its or their consent thereto, and such action
shall not relieve Tenant of liability under this Lease.

               (j) In the event Tenant shall assign this Lease or sublet the
Premises or request the consent of Landlord to any assignment, subletting,
hypothecation or other action requiring Landlord's consent hereunder, then
Tenant shall pay Landlord's then reasonable and standard processing fee and
Landlord's reasonable attorneys' fees incurred in connection therewith.

        17. RULES; NO DISCRIMINATION. Tenant shall faithfully observe and comply
with the rules and regulations annexed to this Lease, and after notice thereof,
all reasonable modifications thereof and additions thereto from time to time
promulgated in writing by Landlord. Landlord shall not be responsible to Tenant
for the nonperformance by any other tenant or occupant of the Building of any of
said rules and regulations. Tenant specifically covenants and agrees that Tenant
shall not discriminate against or segregate any person or group of persons on
account of 



                                       13
<PAGE>   20

race, sex, creed, color, national origin, or ancestry in the occupancy, use,
sublease, tenure or enjoyment of the Premises.

        18. ENTRY BY LANDLORD. Landlord may enter the Premises at reasonable
hours to (a) inspect the same; (b) exhibit the same to prospective purchasers,
lenders or tenants, provided, however, that Landlord shall only exhibit the
Premises to prospective tenants during the final 90 days of Tenant's occupancy
of the Premises; (c) determine whether Tenant is complying with all its
obligations hereunder; (d) supply janitor service and any other service to be
provided by Landlord to Tenant hereunder; (e) post notices of nonresponsibility;
and (f) make repairs required of Landlord under the terms hereof or repairs to
any adjoining space or utility services or make repairs, alterations or
improvements to any other portion of the Building; provided, however, that all
such work shall be done as promptly as reasonably possible and so as to cause as
little interference to Tenant as reasonably possible. Tenant hereby waives any
claim for damages for any inconvenience to or interference with Tenant's
business or any loss of occupancy or quiet enjoyment of the Premises occasioned
by such entry. Landlord shall at all times have and retain a key with which to
unlock all of the doors in, on or about the Premises (excluding Tenant's vaults,
safes and similar areas designated in writing by Tenant in advance); and
Landlord shall have the right to use any and all means which Landlord may deem
proper to open Tenant's doors in an emergency in order to obtain entry to the
Premises, and any entry to the Premises obtained by Landlord in an emergency
shall not be construed or deemed to be a forcible or unlawful entry into or a
detainer of the Premises or an eviction, actual or constructive, of Tenant from
the Premises or any portion thereof.

        19. EVENTS OF DEFAULT. The following events shall constitute Events of
Default under this Lease:

               (a) a default by Tenant in the payment when due of any rent or
other sum payable hereunder and the continuation of such default for a period of
10 days after the same is due, provided that if Tenant has failed three or more
times in any twelve-month period to pay any rent or other sum within 10 days
after the due date, no grace period shall thereafter be applicable hereunder.

               (b) a default by Tenant in the performance of any of the other
terms, covenants, agreements or conditions contained herein and, if the default
is curable, the continuation of such default for a period of 20 days after
notice by Landlord or beyond the time reasonably necessary for cure if the
default is of a nature to require more than 20 days to remedy, provided that if
Tenant has defaulted in the performance of the same obligation three or more
times in any twelve-month period and notice of such default has been given by
Landlord in each instance, no cure period shall thereafter be applicable
hereunder.

               (c) the bankruptcy or insolvency of Tenant, transfer by Tenant in
fraud of creditors, an assignment by Tenant for the benefit of creditors, or the
commencement of any proceedings of any kind by or against Tenant under any
provision of the Federal Bankruptcy Act or under any other insolvency,
bankruptcy or reorganization act unless, in the event any such proceedings are
involuntary, Tenant is discharged from the same within 60 days thereafter;



                                       14
<PAGE>   21

               (d) the appointment of a receiver for a substantial part of the
assets of Tenant;

               (e) the abandonment of the Premises; and

               (f) the levy upon this Lease or any estate of Tenant hereunder by
any attachment or execution and the failure to have such attachment or execution
vacated within 20 days thereafter.

        20. TERMINATION UPON DEFAULT. Upon the occurrence of any Event of
Default by Tenant hereunder, Landlord may, at its option and without any further
notice or demand, in addition to any other rights and remedies given hereunder
or by law, terminate this Lease and exercise its remedies relating thereto in
accordance with the following provisions:

               (a) Landlord shall have the right, so long as the Event of
Default remains uncured, to give notice of termination to Tenant, and on the
date specified in such notice this Lease shall terminate.

               (b) In the event of any such termination of this Lease, Landlord
may then or at any time thereafter by judicial process, re-enter the Premises
and remove therefrom all persons and property and again repossess and enjoy the
Premises, without prejudice to any other remedies that Landlord may have by
reason of Tenant's default or of such termination.

               (c) In the event of any such termination of this Lease, and in
addition to any other rights and remedies Landlord may have, Landlord shall have
all of the rights and remedies of a landlord provided by Section 1951.2 of the
California Civil Code. The amount of damages which Landlord may recover in event
of such termination shall include, without limitation, (1) the worth at the time
of award (computed by discounting such amount at the discount rate of the
Federal Reserve Bank of San Francisco at the time of award plus one percent) of
the amount by which the unpaid rent for the balance of the term after the time
of award exceeds the amount of rental loss that Tenant proves could be
reasonably avoided, (2) all legal expenses and other related costs incurred by
Landlord following Tenant's default, (3) all costs incurred by Landlord in
restoring the Premises to good order and condition, or in remodeling, renovating
or otherwise preparing the Premises for reletting, and (4) all costs (including,
without limitation, any brokerage commissions) incurred by Landlord in reletting
the Premises.

               (d) After terminating this Lease, Landlord may remove any and all
personal property located in the Premises and place such property in a public or
private warehouse or elsewhere at the sole cost and expense of Tenant. In the
event that Tenant shall not immediately pay the cost of storage of such property
after the same has been stored for a period of thirty (30) days or more,
Landlord may sell any or all thereof at a public or private sale in such manner
and at such times and places as Landlord in its sole discretion may deem proper,
without notice to or demand upon Tenant, Tenant waives all claims for damages
that may be caused by Landlord's removing or storing or selling the property as
herein provided, and Tenant shall indemnify and hold Landlord free and harmless
from and against any and all losses, costs and damages, including without
limitation all costs of court and attorneys' fees of Landlord occasioned
thereby.



                                       15
<PAGE>   22

               (e) In the event of the occurrence of any of the events specified
in paragraph 19(c) of this Lease, if Landlord shall not choose to exercise, or
by law shall not be able to exercise, its rights hereunder to terminate this
Lease, then, in addition to any other rights of Landlord hereunder or by law,
(1) Landlord may discontinue the services provided pursuant to paragraph 6 of
this Lease, unless Landlord has received compensation in advance for such
services in the amount of Landlord's reasonable estimate of the compensation
required with respect to such services, and (2) neither Tenant, as
debtor-in-possession, nor any trustee or other person (collectively, the
"Assuming Tenant") shall be entitled to assume this Lease unless on or before
the date of such assumption, the Assuming Tenant (a) cures, or provides adequate
assurance that the Assuming Tenant will promptly cure, any existing default
under this Lease, (b) compensates, or provides adequate assurance that the
Assuming Tenant will promptly compensate, Landlord for any pecuniary loss
(including, without limitation, attorneys' fees and disbursements) resulting
from such default, and (c) provides adequate assurance of future performance
under this Lease. For purposes of this subparagraph (c), "adequate assurance" of
such cure, compensation or future performance shall be effected by the
establishment of an escrow fund for the amount at issue or by bonding.

        21. CONTINUATION AFTER DEFAULT. Even though Tenant has breached this
Lease and abandoned the Premises, this Lease shall continue in effect for so
long as Landlord does not terminate Tenant's right to possession, and Landlord
may enforce all rights and remedies under this Lease, including the right to
recover the rental as it becomes due under this Lease. Acts of maintenance or
preservation or efforts to relet the Premises or the appointment of a receiver
upon initiative of Landlord to protect Landlord's interest under this Lease
shall not constitute a termination of Tenant's right to possession.

        22. OTHER RELIEF. The remedies provided for in this Lease are in
addition to any other remedies available to Landlord at law or in equity by
statute or otherwise.

        23. LANDLORD'S RIGHT TO CURE DEFAULTS. All agreements and provisions to
be performed by Tenant under any of the terms of this Lease shall be at its sole
cost and expense and without any abatement of rental. If Tenant shall fail to
pay any sum of money, other than rental, required to be paid by it hereunder or
shall fail to perform any other act on its part to be performed hereunder and
such failure shall continue for 20 days after notice thereof by Landlord, or
such longer period as may be allowed hereunder, Landlord may, but shall not be
obligated so to do, and without waiving or releasing Tenant from any obligations
of Tenant, make any such payment or perform any such other act on Tenant's part
to be made or performed as in this Lease provided. All sums so paid by Landlord
(with interest at an annual rate equal to four percent (4%) over the annual
prime rate of interest announced publicly by Citibank, N.A., in New York, New
York from time to time, but in no event in excess of the maximum interest rate
permitted by law) and all necessary incidental costs shall be payable to
Landlord on demand.

        24. ATTORNEYS' FEES. If as a result of any breach or default in the
performance of any of the provisions of this Lease, Landlord uses the services
of an attorney in order to secure compliance with such provisions or recover
damages therefor, or to terminate this Lease or evict Tenant, Tenant shall
reimburse Landlord upon demand for any and all reasonable attorneys' fees 



                                       16
<PAGE>   23

and expenses so incurred by Landlord, provided that if Tenant shall be the
prevailing party in any legal action brought by Landlord against Tenant, Tenant
shall be entitled to recover reasonable attorneys' fees and expenses incurred by
Tenant.

        25. EMINENT DOMAIN. If all or any part of the Premises shall be taken as
a result of the exercise of the power of eminent domain, this Lease shall
terminate as to the part so taken as of the date of taking, and, in the case of
a partial taking, either Landlord or Tenant shall have the right to terminate
this Lease as to the balance of the Premises by notice to the other within 30
days after such date, provided, however, that a condition to the exercise by
Tenant of such right to terminate shall be that the portion of the Premises
taken shall be of such extent and nature as substantially to handicap, impede or
impair Tenant's use of the balance of the Premises. In the event of any taking,
Landlord shall be entitled to any and all compensation, damages, income, rent,
awards, or any interest therein whatsoever which may be paid or made in
connection therewith, and Tenant shall have no claim against Landlord for the
value of any unexpired term of this Lease or otherwise. In the event of a
partial taking of the Premises which does not result in a termination of this
Lease, the monthly rental thereafter to be paid shall be equitably reduced.

        26.  SUBORDINATION.

               (a) This Lease shall be subject and subordinate to any ground
lease, mortgage, deed of trust, or any other hypothecation for security now or
hereafter placed upon the Building and to any and all advances made on the
security thereof or Landlord's interest therein, and to all renewals,
modifications, consolidations, replacements and extensions thereof.
Notwithstanding the foregoing, if any mortgagee, trustee or ground lessor shall
elect to have this Lease prior to the lien of its mortgage or deed of trust or
prior to its ground lease, and shall give notice thereof to Tenant, this Lease
shall be deemed prior to the mortgage, deed of trust, or ground lease, whether
this Lease is dated prior or subsequent to the date of the mortgage, deed of
trust or ground lease or the date of recording thereof. In the event any
mortgage or deed of trust to which this Lease is subordinate is foreclosed or a
deed in lieu of foreclosure is given to the mortgagee or beneficiary, Tenant
shall attorn to the purchaser at the foreclosure or to the grantee under the
deed in lieu of foreclosure; in the event any ground lease to which this Lease
is subordinate is terminated, Tenant shall attorn to the ground lessor. Tenant
agrees to execute any documents required to effectuate such subordination, to
make this Lease prior to the lien of any mortgage or deed of trust or ground
lease, or to evidence such attornment.

               (b) In the event any mortgage or deed of trust to which this
Lease is subordinate is foreclosed or a deed in lieu of foreclosure is given to
the mortgagee or beneficiary, or in the event any ground lease to which this
Lease is subordinate is terminated, this Lease shall not be barred, terminated,
cut off or foreclosed nor shall the rights and possession of Tenant hereunder be
disturbed if Tenant shall not then be in default in the payment of rental and
other sums due hereunder or otherwise be in default under the terms of this
Lease, and if Tenant shall attorn to the purchaser, grantee, or ground lessor as
provided in paragraph (a) above or, if requested, enter into a new lease for the
balance of the term hereof upon the same terms and provisions as are contained
in this Lease. Tenant's covenant under paragraph (a) above to subordinate this
Lease to any ground lease, mortgage, deed of trust or other hypothecation
hereafter executed is 



                                       17
<PAGE>   24

conditioned upon each such senior instrument containing the commitments
specified in this paragraph (b).

        27. NO MERGER. The voluntary or other surrender of this Lease by Tenant,
or a mutual cancellation thereof, shall not work a merger, and shall, at the
option of Landlord, terminate all or any existing subleases or subtenancies, or
operate as an assignment to it of an or all such subleases or subtenancies.

        28. SALE. In the event the original Landlord hereunder, or any successor
owner of the Building, shall sell or convey the Building, all liabilities and
obligations on the part of the original Landlord, or such successor owner, under
this Lease accruing thereafter shall terminate, and thereupon all such
liabilities and obligations shall be binding upon the new owner. Tenant agrees
to attorn to such new owner.

        29. ESTOPPEL CERTIFICATE. At any time and from time to time but on not
less than 10 days prior notice by Landlord, Tenant shall execute, acknowledge,
and deliver to Landlord, promptly upon request, a certificate certifying (a)
that this Lease is unmodified and in full force and effect (or, if there have
been modifications, that this Lease is in full force and effect, as modified,
and stating the date and nature of each modification), (b) the date, if any, to
which rental and other sums payable hereunder have been paid, (c) that no notice
has been received by Tenant of any default which has not been cured, except as
to defaults specified in the certificate, and (d) such other matters as may be
reasonably requested by Landlord. Any such certificate may be relied upon by any
prospective purchaser, mortgagee or beneficiary under any deed of trust on the
Building or any part thereof.

        30. NO LIGHT, AIR, OR VIEW EASEMENT. Any diminution or shutting off of
light, air or view by any structure which may be erected on lands adjacent to
the Building shall in no way affect this Lease or impose any liability on
Landlord.

        31. HOLDING OVER.

               (a) If, without objection by Landlord, Tenant holds possession of
the Premises after expiration of the term of this Lease, Tenant shall become a
tenant from month to month upon the terms herein specified but at a monthly
rental equivalent to 150% of the then prevailing monthly rental paid by Tenant
at the expiration of the term of this Lease, payable in advance on or before the
first day of each month. Each party shall give the other notice at least one
month prior to the date of termination of such monthly tenancy of its intention
to terminate such tenancy.

               (b) If, over Landlord's objection, Tenant holds possession of the
Premises after expiration of the term of this Lease or expiration of its
holdover tenancy, without limiting the liability of Tenant for its unauthorized
occupancy of the Premises, Tenant shall pay rent at a monthly rental equivalent
to 200% of the then prevailing monthly rental paid by Tenant at the expiration
of the term of this Lease and shall indemnify Landlord and any replacement
tenant for the Premises for any damages or loss suffered by either Landlord or
the replacement tenant resulting from Tenant's failure timely to vacate the
Premises.



                                       18
<PAGE>   25

        32. SECURITY DEPOSIT. Tenant has deposited with Landlord the sum
specified in the Basic Lease Information (the "deposit"). The deposit shall be
held by Landlord as security for the faithful performance by Tenant of all the
provisions of this Lease to be performed or observed by Tenant. If Tenant fails
to pay rent or other sums due hereunder (after the expiration of any applicable
grace period) or otherwise defaults with respect to any provisions of this Lease
(after the expiration of any applicable grace period), Landlord may use, apply
or retain all or any portion of the deposit for the payment of any rent or other
sum in default or for the payment of any other sum to which Landlord may become
obligated by reason of Tenant's default, or to compensate Landlord for any loss
or damage which Landlord may suffer thereby. If Landlord so uses or applies all
or any portion of the deposit, Tenant shall within 10 days after demand therefor
deposit cash with Landlord in an amount sufficient to restore the deposit to the
full amount thereof and Tenant's failure to do so shall be a material breach of
this Lease. Landlord shall not be required to keep the deposit separate from its
general accounts. If Tenant performs all of Tenant's obligations hereunder, the
deposit, or so much thereof as has not theretofore been applied by Landlord,
shall be returned, without interest, to Tenant (or, at Landlord's option, to the
last assignee, if any, of Tenant's interest hereunder) at the expiration of the
term hereof, and after Tenant has vacated the Premises. No trust relationship is
created herein between Landlord and Tenant with respect to the deposit.

        33. WAIVER. The waiver by Landlord of any agreement, condition or
provision herein contained shall not be deemed to be a waiver of any subsequent
breach of the same or any other agreement, condition or provision herein
contained, nor shall any custom or practice which may grow up between the
parties in the administration of the terms be construed to waive or to lessen
the right of Landlord to insist upon the performance by Tenant in strict
accordance with such terms. The subsequent acceptance of rental hereunder by
Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of
any agreement, condition or provision of this Lease, other than the failure of
Tenant to pay the particular rental so accepted, regardless of Landlord's
knowledge of the preceding breach at the time of acceptance of the rental.

        34. NOTICES AND CONSENTS. All notices, consents, demands and other
communications from one party to the other that are given pursuant to the terms
of this Lease shall be in writing and shall be deemed to have been fully given
when deposited in the United States mail, certified or registered, postage
prepaid, and addressed as follows: to Tenant at the address specified in the
Basic Lease Information, or to such other place as Tenant may from time to time
designate in a notice to Landlord; to Landlord at the address specified in the
Basic Lease Information, or to such other place as Landlord may from time to
time designate in a notice to Tenant; or, in the case of Tenant, delivered to
Tenant at the Premises. Tenant hereby appoints as its agent to receive the
service of all dispossessory or distraint proceedings and notices thereunder the
person in charge of or occupying the Premises at the time, and, if no person
shall be in charge of or occupying the same, then such service may be made by
attaching the same on the main entrance of the Premises.

        35. COMPLETE AGREEMENT. There are no oral agreements between Landlord
and Tenant affecting this Lease, and this Lease supersedes and cancels any and
all previous negotiations, arrangements, brochures, agreements, and
understandings if any, between Landlord and Tenant 



                                       19
<PAGE>   26

or displayed by Landlord to Tenant with respect to the subject matter of this
Lease, the Building or related facilities. There are no representations between
Landlord and Tenant other than those contained in this Lease and all reliance
with respect to any representation is solely upon such representations. All
implied warranties, including implied warranties of merchantability and fitness,
are excluded.

        36. CORPORATE AUTHORITY. If Tenant signs as a corporation, each of the
persons executing this Lease on behalf of Tenant warrants that Tenant is a duly
authorized and existing corporation, that Tenant has and is qualified to do
business in California, that the corporation has full right and authority to
enter into this Lease, and that each and both of the persons signing on behalf
of the corporation were authorized to do so.

        37. PARTNERSHIP AUTHORITY. If Tenant is a partnership, joint venture, or
other unincorporated association, each individual executing this Lease on behalf
of Tenant warrants that this Lease is binding on Tenant and that each and both
of the persons signing on behalf of Tenant were authorized to do so.

        38. LIMITATION OF LIABILITY TO BUILDING. The liability of Landlord to
Tenant for any default by Landlord under this Lease or arising in connection
with Landlord's operation, management, leasing, repair, renovation, alteration,
or any other matter relating to the Building or the Premises, shall be limited
to the interest of Landlord in the Building. Tenant agrees to look solely to
Landlord's interest in the Building for the recovery of any judgment against
Landlord, and Landlord shall not be personally liable for any such judgment or
deficiency after execution thereon. The limitations of liability contained in
this paragraph 38 shall apply equally and inure to the benefit of Landlord, its
successors and their respective, present and future partners of all tiers,
beneficiaries, officers, directors, trustees, shareholders, agents and
employees, and their respective heirs, successors and assigns. Under no
circumstances shall any present or future general partner of Landlord (if
Landlord is a partnership) or individual trustee or beneficiary (if Landlord or
any partner of Landlord is a trust) have any liability for the performance of
Landlord's obligations under this Lease.

        39. BROKERS. Tenant and Landlord each confirms and represents to the
other party that each party has contacted and dealt with solely the broker
identified in the Basic Lease Information and that no other broker has
participated in the negotiation of this Lease or is entitled to any commission
in connection with this Lease.

        40. MISCELLANEOUS. The words "Landlord" and "Tenant" as used herein
shall include the plural as well as the singular. If there be more than one
Tenant, the obligations hereunder imposed upon Tenant shall be joint and
several. Time is of the essence of this Lease and each and all of its
provisions. Submission of this instrument for examination or signature by Tenant
does not constitute a reservation of or option for lease, and it is not
effective as a lease or otherwise until execution and delivery by both Landlord
and Tenant. The agreements, conditions and provisions herein contained shall,
subject to the provisions as to assignment, apply to and bind the heirs,
executors, administrators, successors and assigns of the parties hereto. Tenant
shall not, without the consent of Landlord, use the name of the Building for any
purpose other 



                                       20
<PAGE>   27

than as the address of the business to be conducted by Tenant in the Premises.
If any provision of this Lease shall be determined to be illegal or
unenforceable, such determination shall not affect any other provision of this
Lease and all such other provisions shall remain in full force and effect. This
Lease shall be governed by and construed pursuant to the laws of the State of
California.

        41. EXHIBITS. The exhibit(s) and addendum, if any, specified in the
Basic Lease Information are attached to this Lease and by this reference made a
part hereof.

        41. ADDITIONAL PROVISIONS.

                                    EXHIBIT B

                              RULES AND REGULATIONS

        1. The sidewalks, halls, passages, exits, entrances, shopping malls,
elevators, escalators and stairways of the Building shall not be obstructed by
any of the tenants or used by them for any purpose other than for ingress to and
egress from their respective Premises. The halls, passages, exits, entrances,
shopping malls, elevators, escalators and stairways are not for the general
public, and Landlord shall in all cases retain the right to control and prevent
access thereto of all persons whose presence in the judgment of Landlord would
be prejudicial to the safety, character, reputation and interests of the
Building and its tenants, provided that nothing herein contained shall be
construed to prevent such access to persons with whom any tenant normally deals
in the ordinary course of its business, unless such persons are engaged in
illegal activities. No tenant and no employee or invitee of any tenant shall go
upon the roof of the Building except such roof or portion thereof as may be
contiguous to the Premises of a particular tenant and may be designated in
writing by Landlord as a roof deck or roof garden area.

        2. No sign, placard, picture, name, advertisement or notice visible from
the exterior of any tenant's Premises shall be inscribed, painted, affixed or
otherwise displayed by any tenant on any part of the Building without the prior
written consent of Landlord. Landlord will adopt and furnish to tenants general
guidelines relating to signs inside the Building on the office floors. Each
tenant shall conform to such guidelines, but may request approval of Landlord
for modifications, which approval will not be unreasonably withheld. All
approved signs or lettering on doors shall be printed, painted, affixed or
inscribed at the expense of the tenant by a person approved by Landlord, which
approval will not be unreasonably withheld. Material visible from outside the
Building will not be permitted.

        3. The Premises shall not be used for the storage of merchandise held
for sale to the general public or for lodging. No cooking shall be done or
permitted by an tenant on the Premises, except that use by the tenant of food
and beverage vending machines and Underwriters' Laboratory approved microwave
ovens and equipment for brewing coffee, tea, hot chocolate and similar beverages
shall be permitted, provided that such use is in accordance with all applicable
federal, state and city laws, codes, ordinances, rules and regulations.

        4. No tenant shall employ any person or persons other than Landlord's
janitorial service for the purpose of cleaning the Premises, unless otherwise
approved by Landlord. No person or persons other than those approved by Landlord
shall be permitted to enter the Building for the purpose of cleaning the same.
No tenant shall cause any unnecessary labor by reason of such tenant's
carelessness or indifference in the preservation of good order and cleanliness.
Janitor service will not be furnished on nights when rooms are occupied after
9:30 P.M. unless, by prior arrangement with Landlord, service is extended to a
later hour for specifically designated rooms.

        5. Landlord will furnish each tenant free of charge with two keys to
each door lock in its Premises. Landlord may make a reasonable charge for any
additional keys. No tenant shall have 



                                      B-1
<PAGE>   30

any keys made. No tenant shall alter any lock or install a new or additional
lock or any bolt on any door of its Premises without the prior consent of
Landlord. The tenant shall in each case furnish Landlord with a key for any such
lock. Each tenant, upon the termination of its tenancy, shall deliver to
Landlord all keys to doors in the Building which shall have been furnished to
the tenant.

        6. The freight elevator shall be available for use by all tenants in the
Building, subject to such reasonable scheduling as Landlord in its discretion
shall deem appropriate. The persons employed to move such equipment in or out of
the Building must be acceptable to Landlord. Landlord shall have the right to
prescribe the weight, size and position of all equipment, materials, furniture
or other property brought into the Building. Heavy objects shall, if considered
necessary by Landlord, stand on wood strips of such thickness as is necessary
properly to distribute the weight. Landlord will not be responsible for loss of
or damage to any such property from any cause, and all damage done to the
Building by moving or maintaining such property shall be repaired at the expense
of the tenant.

        7. No tenant shall use or keep in the Premises or the Building any
kerosene, gasoline or inflammable or combustible fluid or material other than
limited quantities thereof reasonably necessary for the operation or maintenance
of office equipment, or, without Landlord's prior approval, use any method of
heating air conditioning other than that supplied by Landlord. No tenant shall
use or keep or permit to be used or kept any foul or noxious gas or substance in
the Premises, or permit or suffer the Premises to be occupied or used in a
manner offensive or objectionable to Landlord or other occupants of the Building
by reason of noise, odors or vibrations, or interfere in any way with other
tenants or those having business therein.

        8. Landlord shall have the right, exercisable without notice and without
liability to any Tenant, to change the name and street address of the Building.

        9. Landlord reserves the right to exclude from the Building between the
hours of 6 P.M. and 7 A.M. and at all hours on Saturdays, Sundays and legal
holidays all persons who do not present a pass to the Building signed by
Landlord. Landlord will furnish passes to persons for whom any tenant requests
the same in writing. Each tenant shall be responsible for all persons for whom
it requests passes and shall be liable to Landlord for all acts of such persons.
Landlord shall in no case be liable for damages for any error with regard to the
admission to or exclusion from the Building of any person. In the case of
invasion, mob, riot, public excitement or other circumstances rendering such
action advisable in Landlord's opinion, Landlord reserves the right to prevent
access to the Building during the continuance of the same by such action as
Landlord may deem appropriate.

        10. The directory of the Building will be provided for the display of
the name and location of tenants and a reasonable number of the principal
officers and employees of tenants, and Landlord reserves the right to exclude
any other names therefrom. Any additional name which a tenant desires to have
added to the directory shall be subject to Landlord's approval and may be
subject to a charge therefor.




                                      B-2
<PAGE>   31

        11. No curtains, draperies, blinds, shutters, shades, screens or other
coverings, hangings or decorations shall be attached to, hung or placed in, or
used in connection with any exterior window in the Building without the prior
consent of Landlord. If consented to by Landlord, such items shall be installed
on the office side of the standard window covering and shall in no way be
visible from the exterior of the Building.

        12. Messenger services and suppliers of bottled water, food, beverages,
and other products or services shall be subject to such reasonable regulations
as may be adopted by Landlord. Landlord may establish a central receiving
station in the Building for delivery and pick-up by all messenger services, and
may limit delivery and pick-up at tenant Premises to Building personnel.

        13. Each tenant shall see that the doors of its Premises are closed and
locked and that all water faucets or apparatus, cooking facilities and office
equipment (excluding office equipment required to be operative at all times) are
shut off before the tenant or its employees leave the Premises at night, so as
to prevent waste or damage, and for any default or carelessness in this regard
the tenant shall be responsible for any damage sustained by other tenants or
occupants of the Building or Landlord. On multiple-tenancy floors, all tenants
shall keep the doors to the Building corridors closed at all times except for
ingress and egress.

        14. The toilets, urinals, wash bowls and other restroom facilities shall
not be used for any purpose other than that for which they were constructed, no
foreign substance of any kind whatsoever shall be thrown therein and the expense
of any breakage, stoppage or damage resulting from the violation of this rule
shall be borne by the tenant who, or whose employees or invitees, shall have
caused it.

        15. Except with the prior consent of Landlord, no tenant shall sell, or
permit the sale at retail, of newspapers, magazines, periodicals, theatre
tickets or any other goods or merchandise to the general public in or on the
Premises, nor shall any tenant carry on, or permit or allow any employee or
other person to carry on, the business of stenography, typewriting or any
similar business in or from the Premises for the service or accommodation of
occupants of any other portion of the Building, nor shall the Premises of any
tenant be used for manufacturing of any kind, or any business or activity other
than that specifically provided for in such tenant's lease.

        16. No tenant shall install any antenna, loudspeaker, or other device on
the roof or exterior walls of the Building.

        17. There shall not be used in any portion of the Building, by any
tenant or its invitees, any hand trucks or other material handling equipment
except those equipped with rubber tires and side guards unless otherwise
approved by Landlord.

        18. Each tenant shall store its refuse within its Premises. No material
shall be placed in the refuse boxes or receptacles if such material is of such
nature that it may not be disposed of in the ordinary and customary manner of
removing and disposing of refuse in the City and County of San Francisco without
being in violation of any law or ordinance governing such disposal. All 



                                      B-3
<PAGE>   32

refuse disposal shall be made only through entryways and elevators provided for
such purposes and at such times as Landlord shall designate.

        19. Canvassing, peddling, soliciting, and distribution of handbills or
any other written materials in the Building are prohibited, and each tenant
shall cooperate to prevent the same.

        20. The requirements of the tenants will be attended to only upon
application by telephone or in person at the office of the Building. Employees
of Landlord shall not perform any work or do anything outside of their regular
duties unless under special instructions from Landlord.

        21. Landlord may waive any one or more of these Rules and Regulations
for the benefit of any particular tenant or tenants, but no such waiver by
Landlord shall be construed as a waiver of such Rules and Regulations in favor
of any other tenant or tenants, nor prevent Landlord from thereafter enforcing
any such Rules and Regulations against any or all of the tenants of the
Building.

        22. These Rules and Regulations are in addition to, and shall not be
construed to in any way modify or amend, in whole or in part, the terms,
covenants, agreements and conditions of any lease of Premises in the Building.

        23. Landlord reserves the right to make such other and reasonable rules
and regulations as in its judgment may from time to time be needed for the
safety, care and cleanliness of the Building, and for the preservation of good
order therein.

                                    EXHIBIT C

                           IMPROVEMENT OF THE PREMISES

        1. The Work. Landlord, through Landlord's contractor, shall construct
and install in the Premises, substantially in accordance with plans, working
drawings and specifications ("Tenant's Plans") prepared by Landlord's architects
and engineers and approved by Tenant, the improvements ("The Work") described in
Tenant's Plans (except work described in paragraph 6 hereof). Tenant's Plans
shall be based upon and derived from the preliminary architectural plans
prepared by Thomas Lew, dated December 9, 1993 and revised December 20, 1993
(P1), including the modification or deletion of notes No. 1 and No. 4 based on
the final costs of performing The Work. The costs of preparing Tenant's Plans
and performing The Work shall be paid by Landlord, as set forth in this Exhibit
C. The Work shall be performed in a good and workmanlike manner and in
accordance with applicable laws and regulations. The quantities, character and
manner of construction and installation of The Work shall be subject to all
limitations and restrictions imposed by laws, regulations and guidelines
relating to health, safety, the environment, handicapped persons and
conservations of energy adopted by any public or government authority.

        2.  Tenant's Plans and Construction.

        (a) As soon as reasonably possible Landlord shall submit Tenant's Plans
to Tenant for Tenant's written approval. Tenant shall have two (2) working days
to review Tenant's Plans and submit to Landlord any changes, comments, and
revisions to the same. Tenant's Plans and any revisions thereto requested by
Tenant, shall be prepared by Landlord's architect and shall comply with all
applicable codes, laws, ordinances, rules and regulations and shall be in a form
sufficient to secure the approval of all government authorities with
jurisdiction over the approval thereof. If Tenant approves Tenant's Plan,
Landlord shall deliver to Tenant an estimate ("Cost Estimate") of the cost of
completing The Work in the Premises (which Cost Estimate shall include the cost
of preparing Tenant's Plans). Tenant shall either (i) approve the Cost Estimate
by written notice to Landlord, (ii) request additional changes to Tenant's
Plans, whereby Landlord shall revise Tenant's Plans in accordance with Tenant's
request and resubmit to Tenant for its approval both the revised Tenant's Plans
and revised Cost Estimate. Any changes to Tenant's Plans prior to Tenant's
approval of the Cost Estimate shall be not considered a change pursuant to
Paragraph 4 of this Exhibit C. Tenant's approval or Tenant's Plans shall
constitute authorization for Landlord to perform The Work substantially in
accordance with Tenant's Plans. In the absence of such authorization, Landlord
shall not be obligated to commence The Work. Landlord's contractor shall
complete The Work in the Premises substantially in accordance with Tenant's
Plans.

        (b) All interior decorating services, such as the selection of colors of
wall paint, wall coverings, carpeting and all other decorator selection work,
required by Tenant shall be provided by Tenant at Tenant's expense.

        3. Landlord's Contribution. As Landlord's Contribution for the costs of
preparing Tenant's Plans and performing The Work, Landlord shall provide Tenant
an allowance 



                                      C-1
<PAGE>   34

"Landlord's Contribution" in an amount not to exceed $60,789.00. Landlord shall
pay Landlord's Contribution directly to Landlord's architects, engineers,
consultants or suppliers or to Landlord's contractor for the account of Tenant,
in installments, or as professional services are rendered, or The Work is
performed. Landlord's Contributions shall include all architectural fees for
Tenant's Plans. If costs incurred in preparing Tenant's Plans and performing The
Work exceed Landlord's Contribution, and provided that The Work is constructed
in accordance with Tenant's Plans, Tenant shall pay to Landlord, as Additional
Rent ("Additional Rent") an amount up to and not exceeding Ten Thousand Dollars
and 00/100 cents ($10,000.00) ("Additional Contribution"). Tenant shall pay the
Additional Rent to Landlord (payable at the same time and place as monthly
installments of Base Rent), in equal monthly installments, amortized over a five
(5) year period, with interest at 9% per annum, commencing on the first day of
the sixth (6th) full calendar month of the Term, with any residual due upon
expiration of the Term. If any cost associated with preparing Tenant's Plans and

within thirty (30) days of Landlord's written notice that such cost are due and
payable.

        4. Changes. If Tenant requests any change in The Work subsequent to

written notice to Landlord. Each such request shall be accompanied, if
necessary, by plans, drawings and specifications prepared by Landlord's
architects or engineers, at Tenant's expense, necessary to show and explain such
change from the previously approved Tenant's Plans. Landlord shall have
Landlord's contractor give Tenant an estimate of the construction cost, if any,
for such change. Landlord shall have Landlord's contractor also give Tenant an
estimate of the delay in substantial completion of The Work, if any, which will
be incurred for such change and which Tenant shall be liable for in accordance
with Paragraph 5 below. Tenant shall, within five (5) business days after
receipt of such estimate, notify Landlord in writing to proceed or not to
proceed with such change. If Tenant approves the estimate and requests the
change be constructed then Tenant shall be liable for, and pay to Landlord as
Additional Rent (at such times and in such manner as provided in Paragraph 3)
the actual cost of The Work. In the absence of such written notice to proceed,
Landlord shall not be obligated to make the change requested by Tenant and
Landlord shall proceed with The Work in accordance with the previously approved
Tenant's Plans.

        5. Delay. Tenant shall be liable for, and shall pay all costs and
expenses incurred by Landlord in connection with any delay ("Tenant Delay") in
the commencement or completion of The Work caused by (i) Tenant's failure
promptly to approve Tenant's Plans, (ii) Tenant's requirement of additional or
different work, (iii) interruption of The Work in question to accommodate
performance of other Tenant requested work outside the scope of The Work in
question , (iv) any changes, additions, or alterations to The Work which are
requested by Tenant as to which Landlord has notified Tenant that such change
will cause a delay, (v) Tenant's failure to take any action required of Tenant
under the Lease or this Addendum, (vi) any interruption or interference in the
construction caused by Tenant or its architects, planners, engineers,
contractors, subcontractors, laborers or suppliers, or (vii) any other delay
requested or caused by Tenant.

contractors and conduct Tenant's work in such a manner as to maintain harmonious

                            ADDENDUM TO OFFICE LEASE

        This Addendum to Office Lease shall constitute a part of that certain
120 Montgomery Street Office Lease dated February 4, 1994 (the "Lease") between
The Equitable Montgomery Company ("Landlord") and Orrell & Company, Inc.
("Tenant"). Landlord and Tenant desire to amend the Lease as hereinafter
provided.

        NOW, THEREFORE, notwithstanding anything to the contrary contained in
the Lease, Landlord and Tenant agree as follows:

        1. Definitions.  The definitions in the Lease shall also apply to this
Addendum unless herein otherwise indicated.

        2. Rent Credit. Notwithstanding anything to the contrary in the Lease,
Base Rent shall be abated during the first five (5) months of the Lease Term.
Accordingly, no Base Rental or operating expenses shall be payable for the first
five (5) months of the term of the Lease. Thereafter, throughout the term of the
Lease, base annual rental shall be as provided in Article H of the Basic Lease
Information and Paragraph 3(a) of the Lease and shall be due and payable in
accordance with the terms of the Lease.

        3. Term Commencement and Substantial Completion. Notwithstanding any
provision of the Lease to the contrary, the commencement date for the term of
the Lease shall be the date of Substantial Completion of the Work constituting
the improvements to the Premises as defined in Exhibit C to this Lease. Landlord
and Tenant shall use reasonable efforts to effect 



                                       1
<PAGE>   37

Substantial Completion of the Work constituting the improvements to the Premises
by March 15, 1994. "Substantial Completion" shall be defined as the condition of
the improvements when (i) the Work has been performed substantially in
accordance with Tenant's Plans as defined in Exhibit C to this Lease (except for
finishing details of construction, decoration, mechanical and other adjustments
or items commonly found on an architectural punch list, all of which do not
materially interfere with Tenant's permitted use of the demised Premises) and
Substantial Completion shall be deemed to have occurred notwithstanding a
requirement on the part of the contractor to complete "punch list" or similar
corrective work, and (ii) a certificate of occupancy with respect to the demised
Premises has been issued by the City and County of San Francisco, if required.
If Landlord is delayed in substantially completing any Work as a result of any
Tenant Delay, (as defined in Exhibit C to this Lease) then the date of
Substantial Completion of such Work shall be deemed to have been the date upon
which such Work would have been substantially completed in the absence of such
Tenant Delay. Landlord will diligently pursue completion of all punch list
items. As and when requested by Tenant, Landlord will give Tenant the
contractor's then best estimate of the date of Substantial Completion of any
Work then in progress. The date of Substantial Completion of any Work shall be
fixed by Landlord in a notice to Tenant, which notice shall state that the
demised Premises are, or prior to the date stated in such notice will be,
substantially complete. Tenant agrees to acknowledge in writing all dates of
Substantial Completion of Work with respect to the demised Premises as well as
the date upon which the term of the Lease commenced, as and when requested to do
so by Landlord. By occupying the demised Premises, Tenant accepts the demised
Premises as being in the condition 



                                       2
<PAGE>   38

in which Landlord is obligated to deliver the demised Premises, subject only to
the completion or correction of "Punch list" items.

        4. Option to Extend Term. Subject to the provisions of this Paragraph,
Tenant shall have the option to extend the term of this Lease (the "Extension
Option") for a period of five (5) years (the "Renewal Term") provided that:

               (a) Tenant gives Landlord written notice of Tenant's intention to
exercise the Extension Option no later than nine (9) months prior to the
expiration of the term of the Lease, and;

               (b) At the time of the aforesaid notice, at the time the
Extension Option is exercised and at the commencement of the Renewal Term, the
Lease must be in full force and effect, Tenant must not be then in default under
the Lease, Tenant shall not have been in monetary default (for more than ten
(10) days after written notice of such default from Landlord) or in material
nonmonetary default from Landlord, or if the cure of such default reasonably
requires more than thirty (30) days, Tenant shall not have commenced to cure the
same within thirty (30) days after written notice of such default from Landlord
and shall not have diligently proceeded to complete such cure) more than three
times during the last five years of the initial term of the Lease or at any time
during the last five years of the initial term for more than thirty days,
Tenant's interest under the Lease must not have been assigned by operation of
law or otherwise, Tenant must be in occupancy of the entire demised Premises,
and Tenant must not have sublet any portion thereof; and



                                       3
<PAGE>   39

               (c) All of the terms, covenants and conditions of the Lease shall
remain in effect during the Renewal Term, except that (i) no rent concessions or
renewal or expansion option shall be included and (ii) the base annual rental
shall be at fair market rental value of the demised Premises for the Renewal
Term, meaning the monthly rental rate per square foot prevailing at the
commencement of the Renewal Term for five (5) year leases then being entered
into for comparable space in first class buildings in the San Francisco
Financial District and used for comparable purposes.

        Within thirty (30) days after Landlord's receipt of the Tenant's notice
specified in subparagraph (a) above, Landlord and Tenant shall meet, negotiate
and attempt to agree upon the fair market rental value for the demised Premises
for the Renewal Term. If Landlord and Tenant have not agreed in writing on such
fair market value within sixty (60) days of Landlord's receipt of Tenant's
notice specified in subparagraph (as) above, then, upon written notice of either
party to the other requesting a determination of such fair market rental value
by real estate brokers such fair market rental value shall be determined by real
estate brokers in accordance with the terms of Paragraph 5 of this Addendum.

        5. Determination of Fair Market Rental Value. Whenever, pursuant to this
Addendum, fair market rental is to be determined by real estate brokers, the
procedures of this Paragraph 5 shall apply.

        Each party shall select (and pay the fees of) a disinterested real
estate broker with at least five (5) years of commercial real estate office
leasing experience in the City and County of San Francisco. Each party shall,
within ten (10) days after the notice of request for the determination 



                                       4
<PAGE>   40

of fair market rental value by brokers, notify the other party of the name and
address of the real estate broker selected by such party. The two brokers
selected shall attempt to determine the fair market rental value of the demised
Premises for the Renewal Term. If either Landlord or Tenant shall fail timely to
so appoint a broker, the appointed broker shall select the second broker
(subject to the above selection criteria) within ten (10) days after the failure
of Landlord or Tenant, as the case may be, to so appoint. Such brokers shall,
within thirty (30) days after the appointment of the last of them to be
appointed, complete their determinations of fair market value and submit their
reports to Landlord and Tenant. If the valuations vary by 5% or less of the
higher value, the fair market rental value shall be the average of the values.
If the values vary by more than 5% of the higher value, the two brokers shall,
within ten (10) days after submission of the last of the reports, appoint a
third broker who shall be similarly qualified. If the two brokers shall be
unable to agree timely on the selection of a third broker, then the third broker
shall be appointed by the presiding Judge of the Superior Court for the City and
County of San Francisco. The third broker shall, within thirty (30) days after
his or her appointment, choose as the fair market rental value of the demised
Premises for the Renewal Term one of the values calculated by the other two
brokers and notify Landlord and Tenant of his or her choice. The third broker
shall have no right to propose a middle ground. Landlord and Tenant shall each
pay the respective fees of its selected broker, or of the broker selected on its
behalf by the other's selected broker if Landlord or Tenant shall fail to timely
appoint, as provided above. The fees of a third broker, if there be one, shall
be paid one-half by Landlord and one-half by Tenant.

<PAGE>   41

        6. Relocation Expense Allowance. Within thirty (30) days of the date of
Tenant's occupancy in Premises, Landlord shall reimburse Tenant, upon Tenant
forwarding copies of paid invoices to Landlord, up to Four Thousand Four Hundred
and Five Dollars and 00/100 cents ($4,405.00) for costs associated with Tenant's
move to the new Premises. Relocation expenses shall be defined as Tenant moving
costs strictly limited to relocating Tenant's furniture and personal property to
the Premises. Such moving costs shall not include telephone systems, telephone
cabling or data cabling costs.

        7. Irrevocable Standby Letter of Credit.

               (a) In addition to the security deposit in the amount of
$5,432.83 to be provided pursuant to Paragraph 32 of the Lease, Tenant shall
provide Landlord on March 1, 1994, and maintain in effect throughout the term of
the Lease (subject to Paragraph B below), an Irrevocable Standby Letter of
Credit in the amount of $30,000.00 (the "Letter of Credit"), issued in favor of
the Equitable Montgomery Company as beneficiary ("EMC") by a banking institution
acceptable to EMC. EMC shall be entitled to draw down upon the Letter of Credit
in whole or in part as and to the extent that Landlord would be entitled to use
or apply all or any portion of the security deposit under Paragraph 32 of the
Lease; provided, however, EMC may not draw down upon any portion of the Letter
of Credit until after the expiration of any applicable grace period provided to
Tenant hereunder. If EMC draws down upon any portion of the Letter of Credit as
provided herein, Tenant shall restore the Letter of Credit to the full amount
then required by the terms of this Paragraph 7. The terms of the Letter of
Credit shall entitle Landlord to draw upon the Letter of Credit in whole or in
part upon certification from any individual purportedly acting for Landlord that
it is entitled under the Lease to make such draw, and shall further entitle




                                       6
<PAGE>   42

Landlord to draw down the entire amount of the Letter of Credit in the event
Tenant fails to deliver to Landlord thirty (30) days prior to the expiration
date of the current Letter of Credit a renewal Letter of Credit effective as of
the expiration of the current term of the Letter of Credit. The initial term of
the Letter of Credit shall be one (1) year, and Tenant shall renew it for
successive one-year periods thereafter, subject to subparagraph (b) below. The
issuer of the Letter of Credit shall provide Landlord with not less than
forty-five (45) days' notice prior to cancellation. If Landlord is entitled to
draw down the entire Letter of Credit based on a failure to renew, until such
time as the Letter of Credit has been renewed, Landlord shall deposit the
proceeds in an interest bearing money market account at Wells Fargo Bank or
another Federally Insured Bank or Savings and Loan. Interest shall be retained
in such account. Landlord may thereafter withdraw funds directly from such
account as and to the extent Landlord would have been entitled to draw upon the
Letter of Credit. Landlord shall bear no liability whatsoever for any loss of
principal, interest or measure of interest in such account. Any funds remaining
in such account on the date that the Letter of Credit would otherwise expire
shall be returned to Tenant.

               (b) In the event that no event of default has occurred under the
Lease and is continuing, no monetary event of the default has occurred under the
Lease (whether or not such event of default shall be continuing), and no facts
or circumstances then exist that would, with the passage of time, the giving of
notice, or both, constitute an event of default, the amount of the Letter of
Credit shall be reduced to zero effective as of the close of the twenty fifth
(25th) calendar month of the Lease Term.



                                       7
<PAGE>   43

        8. Time is of the Essence. Time is of the essence of the obligations of
the Tenant under the Lease and under this Addendum.

        9. Conflicts. If there are any conflicts between the provisions of the
Lease and this Addendum, the provisions of this Addendum shall prevail.

        10. Ratification of Lease. Landlord and Tenant hereby ratify and confirm
all of the provisions of the Lease as amended by this Addendum.

        1.1 Real Property, Building and Premises. Upon and subject to the terms,
covenants and conditions hereinafter set forth in this Lease, Landlord hereby

referred to as the "REAL PROPERTY." Tenant is hereby granted the right to the
nonexclusive use of the common corridors and hallways, stairwells, elevators,
restrooms and other public or common areas located on the Real Property;
provided, however, that (i) the manner in which such public and common areas are
maintained and operated shall be at the sole discretion of Landlord and the use
thereof shall be subject to such rules, regulations and restrictions as Landlord
may make from time to time, and (ii) Tenant shall have no right to use any
portion of the Building or of the Real Property for parking for Tenant or
Tenant's employees, visitors and/or invitees. Landlord reserves the right to

                                   LEASE TERM

        The terms and provisions of this Lease shall be effective as of the date

Rent. The term of this Lease (the "LEASE TERM") shall be as set forth in Section
7.1 of the Summary and shall commence on the date (the "LEASE COMMENCEMENT

        Tenant shall pay, without notice or demand, to Landlord or Landlord's
agent at the management office of the Building, or at such other place as
Landlord may from time to time designate in writing, in currency or a check for
currency which, at the time of payment, is legal tender for private or public
debts in the United States of America, base rent ("BASE RENT") as set forth in
Section 8 of the Summary, payable in equal monthly installments as set forth in
Section 8 of the Summary in advance on or before the first day of each and every
month during the Lease Term, without any setoff or deduction whatsoever. The
Base Rent for the first full month of the Lease Term shall be paid at the time
of Tenant's execution of this Lease. If any rental payment date (including the
Lease Commencement Date) falls on a day of the month other than the first day of
such month or if any rental payment is for a period which is shorter than one
month, then the rental for any such fractional month shall be a proportionate
amount of a full calendar month's rental based on the proportion that the number
of days in such fractional month bears to the number of days in the calendar
month during which such fractional month occurs. All other payments or
adjustments required to be made under the terms of this Lease that require
proration on a time basis shall be prorated on the same basis.

are defined in Sections 4.2.8 and 4.2.3 of this Lease, respectively, which are
in excess of the amount of Direct Expenses applicable to the "BASE YEAR," as
that term is defined in Section 4.2.1 of this Lease. Such additional rent,

limitation on other obligations of Tenant which shall survive the expiration of
the Lease Term, the obligations of Tenant to pay the Additional Rent provided
for in this Article 4 shall survive the expiration of the Lease Term.

Expense Year involved in any such change.

        4.2.5 "OPERATING EXPENSES" shall mean all expenses, costs and amounts of
every kind and nature which Landlord shall pay during any Expense Year because
of or in connection with the ownership, management, maintenance, repair,
replacement, restoration or operation of the Building and Real Property,
including, without limitation, any amounts paid for: (i) the cost of supplying
all utilities (excluding the cost of electricity consumed in the Premises and
the premises of other tenants in the Building since Tenant is separately paying
for the cost of electricity consumed in the Premises pursuant to Section 6.1.2
below), the cost of operating, maintaining. repairing, renovating and managing
the utility systems, mechanical systems, sanitary and storm drainage systems,
any elevator systems and all other "Systems and Equipment" (as defined in
Section 4.2.6 of this Lease), and the cost of supplies and equipment and
maintenance and service contracts in connection therewith; (ii) the cost of
licenses, certificates, permits and inspections, and the cost of contesting the
validity or applicability of any governmental enactments which may affect

                                       3

Property, and employer's Social Security taxes, unemployment taxes or insurance,
and any other taxes which may be levied on such wages, salaries, compensation
and benefits; (vii) payments under any easement, license, operating agreement,
declaration, restrictive covenant, underlying or ground lease (excluding rent),
or instrument pertaining to the sharing of costs by the Building or Real
Property; (viii) the cost of janitorial service (excluding the cost to provide

coverings, ceiling tiles and fixtures in lobbies, corridors, restrooms and other
common or public areas or facilities, maintenance and replacement of curbs and

(I) which are intended as a labor-saving device or to elect other economies in
the operation or maintenance of the Building and Real Property, (II) made to the
Building or Real Property after the Lease Commencement Date that are required
under any governmental law or regulation, or (III) which are reasonably
determined by Landlord to be in the best interests of the Building and/or the
Real Property; provided, however, that if any such cost described in (I), (II)
or (III) above, is a capital expenditure, such costs shall be amortized
(including interest on the unamortized cost) over its useful life as Landlord
shall reasonably determine. If Landlord is not furnishing any particular work or
service (the cost of which, if performed by Landlord, would be included in
Operating Expenses) to a tenant who has undertaken to perform such work or
service in lieu of the performance thereof by Landlord, Operating Expenses shall
be deemed to be increased by an amount equal to the additional Operating
Expenses which would reasonably have been incurred during such period by
Landlord if it had at its own expense furnished such work or service to such
tenant. If the Building is then ninety-five percent occupied during all or a
portion of any Expense Year (including the Base Year), Landlord shall make an
appropriate adjustment to the variable components of Operating Expenses for such
year or applicable portion thereof, employing sound accounting and management
principles, to determine the amount of Operating Expenses that would have been
paid had ninety-five percent of the Building been occupied; and the amount so
determined shall be deemed to have been the amount of Operating Expenses for
such year, or applicable portion thereof Landlord shall have the right, from
time to time, to equitably allocate some or all of the Operating Expenses among
different tenants of the Building (the "COST POOLS"). Such Cost Pools may
include, without limitation, the office space tenants and retail space tenants
of the Building. Notwithstanding anything to the contrary set forth in this
Article 4, when calculating Direct Expenses for the Base Year, Operating
Expenses shall exclude market-wide labor-rate increases due to extraordinary
circumstances, including, but not limited to, boycotts and strikes, and utility
rate increases due to extraordinary circumstances including, but not limited to,
conservation surcharges, boycotts, embargoes or other shortages, and costs
relating to capital improvements.

        Notwithstanding the foregoing, Operating Expenses shall not, however,
include: (A) costs of leasing commissions, attorneys' fees and other costs and
expenses incurred in connection with negotiations or disputes with present or
prospective tenants or other occupants of the Building; (B) costs (including
permit, license and inspection costs) incurred in renovating


                                       4
<PAGE>   11
or otherwise improving, decorating or redecorating rentable space for other
tenants or vacant rentable space; (C) costs incurred due to the violation by
Landlord of the terms and conditions of any lease of space in the Building; (D)
costs of overhead or profit increment paid to Landlord or to subsidiaries or
affiliates of Landlord for services in or in connection with the Building to the
extent the same exceeds the costs of overhead and profit increment included in
the costs of such services which could be obtained from third parties on a
competitive basis; (E) except as otherwise specifically provided in this Section
4.2.5, costs of interest on debt or amortization on any mortgages, and rent
payable under any ground lease of the Real Property; and (F) costs incurred in
connection with correcting existing violations of the Building and Real Property
of applicable laws in effect as of the date of this Lease, including, without
limitation, any costs to remediate or mitigate any Hazardous Materials (as such
term is defined in Article 5 below) existing in the Building or Real Property in
violation of Hazardous Materials laws as of such date.

               4.2.6 "SYSTEMS AND EQUIPMENT" shall mean any plant, machinery,
transformers, duct work, cable, wires, and other equipment, facilities, and
systems designed to supply heat, ventilation, air conditioning and humidity or
any other services or utilities, or comprising or serving as any component or
portion of the electrical, gas, steam, plumbing, sprinkler, communications,
alarm, security, or fire/life safety systems or equipment, or any other
mechanical, electrical, electronic, computer or other systems or equipment which
serve the Building in whole or in part.

               4.2.7 "TAX EXPENSES" shall mean all federal, state, county, or
local governmental or municipal taxes, fees, assessments, charges or other
impositions of every kind and nature, whether general, special, ordinary or
extraordinary, (including, without limitation, real estate taxes, general and
special assessments, transit assessments, fees and taxes, child care subsidies,
fees and/or assessments, job training subsidies, fees and/or assessments, open
space fees and/or assessments, housing subsidies and/or housing fund fees or
assessments, public art fees and/or assessments, leasehold taxes or taxes based
upon the receipt of rent, including gross receipts or sales taxes applicable to
the receipt of rent, personal property taxes imposed upon the fixtures,
machinery, equipment, apparatus, systems and equipment, appurtenances, furniture
and other personal property used in connection with the Real Property), which
Landlord shall pay during any Expense Year because of or in connection with the
ownership, leasing and operation of the Real Property or Landlord's interest
therein. For purposes of this Lease, Tax Expenses shall be calculated as if the
tenant improvements in the Building were fully constructed and the Real
Property, the Building, and all tenant improvements in the Building were fully
assessed for real estate tax purposes.

                      4.2.7.1 Tax Expenses shall include, without limitation:

                              (i) Any tax on Landlord's rent, right to rent or
other income from the Real Property or as against Landlord's business of leasing
any of the Real Property;

                              (ii) Any assessment, tax, fee, levy or charge in
addition to, or in substitution, partially or totally, of any assessment, tax,
fee, levy or charge previously included


                                       5
<PAGE>   12
within the definition of real property tax, it being acknowledged by Tenant and
Landlord that Proposition 13 was adopted by the voters of the State of
California in the June 1978 election ("PROPOSITION 13") and that assessments,
taxes, fees, levies and charges may be imposed by governmental agencies for such
services as fire protection, street, sidewalk and road maintenance, refuse
removal and for other governmental services formerly provided without charge to
property owners or occupants. It is the intention of Tenant and Landlord that
all such new and increased assessments, taxes, fees, levies, and charges and all
similar assessments, taxes, fees, levies and charges be included within the
definition of Tax Expenses for purposes of this Lease;

                              (iii) Any assessment, tax, fee, levy, or charge
allocable to or measured by the area of the Premises or the rent payable
hereunder, including, without limitation, any gross income tax upon or with
respect to the possession, leasing, operating, management, maintenance,
alteration, repair, use or occupancy by Tenant of the Premises, or any portion
thereof;

                              (iv) Any assessment, tax, fee, levy or charge,
upon this transaction or any document to which Tenant is a party. creating or
transferring an interest or an estate in the Premises; and

                              (v) Any reasonable expenses incurred by Landlord
in attempting to protest, reduce or minimize Tax Expenses.

                      4.2.7.2 In no event shall Tax Expenses for any Expense
Year be less than the component of Tax Expenses comprising a portion of the Base
Year.

                      4.2.7.3 Notwithstanding anything to the contrary contained
in this Section 4.2.7, there shall be excluded from Tax Expenses (i) all excess
profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and
succession taxes, estate taxes, federal and state net income taxes, and other
taxes to the extent applicable to Landlord's net income (as opposed to rents,
receipts or income attributable to operations at the Building or Real Property),
(ii) any items included as Operating Expenses, and (iii) any items paid by
Tenant under Section 4.4 of this Lease.

               4.2.8 "TENANT'S SHARE" shall mean the percentage set forth in
Section 9.2 of the Summary. Tenant's Share was calculated by multiplying the
number of rentable square feet of the Premises by 100 and dividing the product
by the total rentable square feet in the Building. In the event either the
rentable square feet of the Premises and/or the total rentable square feet of
the Building is changed, Tenant's Share shall be appropriately adjusted, and, as
to the Expense Year in which such change occurs, Tenant's Share for such year
shall be determined on the basis of the number of days during such Expense Year
that each such Tenant's Share was in effect.

        4.3 Calculation and Payment of Additional Rent.

               4.3.1 Calculation of Excess. If for any Expense Year ending or
commencing within the Lease Term, Tenant's Share of Direct Expenses for such
Expense Year exceeds


                                       6
<PAGE>   13
Tenant's Share of Direct Expenses for the Base Year, then Tenant shall pay to
Landlord, in the manner set forth in Section 4.3.2, below, and as Additional
Rent, an amount equal to the excess (the "EXCESS"); provided, however, that for
the first twelve months of the Lease Term, Tenant shall not be obligated to pay
any Excess.

               4.3.2 Statement of Actual Direct Expenses and Payment by Tenant.
Landlord shall endeavor to give to Tenant on or before the first day of April
following the end of each Expense Year, a statement (the "STATEMENT") which
shall state the Direct Expenses incurred or accrued for such preceding Expense
Year, and which shall indicate the amount, if any, of any Excess. Upon receipt
of the Statement for each Expense Year ending during the Lease Term, if an
Excess is present, Tenant shall pay, with its next installment of Base Rent due,
the full amount of the Excess for such Expense Year, less the amounts, if any,
paid during such Expense Year as "ESTIMATED EXCESS," as that term is defined in
Section 4.3.3 of this Lease. The failure of Landlord to timely furnish the
Statement for any Expense Year shall not prejudice Landlord from enforcing its
rights under this Article 4. Even though the Lease Term has expired and Tenant
has vacated the Premises, when the final determination is made of Tenant's Share
of the Direct Expenses for the Expense Year in which this Lease terminates, if
an Excess is present, Tenant shall immediately pay to Landlord an amount as
calculated pursuant to the provisions of Section 4.3.1 of this Lease. The
provisions of this Section 4.3.2 shall survive the expiration or earlier
termination of the Lease Term.

               4.3.3 Statement of Estimated Direct Expenses. In addition,
Landlord shall endeavor to give Tenant a yearly expense estimate statement (the
"ESTIMATE STATEMENT") which shall set forth Landlord's reasonable estimate (the
"ESTIMATE") of what the total amount of Direct Expenses for the then-current
Expense Year shall be and the estimated Excess (the "ESTIMATED EXCESS") as
calculated by comparing Tenant's Share of Direct Expenses, which shall be based
upon the Estimate, to Tenant's Share of Direct Expenses for the Base Year. The
failure of Landlord to timely furnish the Estimate Statement for any Expense
Year shall not preclude Landlord from enforcing its rights to collect any
Estimated Excess under this Article 4. If pursuant to the Estimate Statement an
Estimated Excess is calculated for the then-current Expense Year, Tenant shall
pay, with its next installment of Base Rent due, a fraction of the Estimated
Excess for the then-current Expense Year (reduced by any amounts paid pursuant
to the last sentence of this Section 4.3.3). Such fraction shall have as its
numerator the number of months which have elapsed in such current Expense Year
to the month of such payment, both months inclusive, and shall have twelve (12)
as its denominator. Until a new Estimate Statement is furnished, Tenant shall
pay monthly, with the monthly Base Rent installments, an amount equal to
one-twelfth (1/12) of the total Estimated Excess set forth in the previous
Estimate Statement delivered by Landlord to Tenant.

        4.4 Taxes and Other Charges for Which Tenant Is Directly Responsible.
Tenant shall reimburse Landlord upon demand for any and all taxes or assessments
required to be paid by Landlord (except to the extent included in Tax Expenses
by Landlord), excluding state, local and federal personal or corporate income
taxes measured by the net income of Landlord from all sources and estate and
inheritance taxes, whether or not now customary or within the contemplation of
the parties hereto, when:


                                       7
<PAGE>   14

               4.4.1 Said taxes are measured by or reasonably attributable to
the cost or value of Tenant's equipment, furniture. fixtures and other personal
property located in the Premises, or by the cost or value of any leasehold
improvements made in or to the Premises by or for Tenant, to the extent the cost
or value of such leasehold improvements exceeds the cost or value of a building
standard build-out as determined by Landlord regardless of whether title to such
improvements shall be vested in Tenant or Landlord;

               4.4.2 Said taxes are assessed upon or with respect to the
possession, leasing, operation, management, maintenance, alteration, repair, use
or occupancy by Tenant of the Premises or any portion of the Real Property; or

               4.4.3 Said taxes are assessed upon this transaction or any
document to which Tenant is a party creating or transferring an interest or an
estate in the Premises.

        4.5 Late Charges. If any installment of Rent or any other sum due from
Tenant shall not be received by Landlord or Landlord's designee by the due date
therefor, then Tenant shall pay to Landlord a late charge equal to five percent
(5%) of the amount due plus any attorneys' fees incurred by Landlord by reason
of Tenant's failure to pay Rent and/or other charges when due hereunder. The
late charge shall be deemed Additional Rent and the right to require it shall be
in addition to all of Landlord's other rights and remedies hereunder, at law
and/or in equity and shall not be construed as liquidated damages or as limiting
Landlord's remedies in any manner. In addition to the late charge described
above, any Rent or other amounts owing hereunder which are not paid by the date
they are due shall thereafter bear interest until paid at a rate (the "INTEREST
RATE") equal to the lesser of (i) the "PRIME RATE" or "REFERENCE RATE" announced
from time to time by the Bank of America (or such reasonable comparable national
banking institution as selected by Landlord in the event Bank of America ceases
to exist or publish a Prime Rate or Reference Rate), plus four percent (4%), or
(ii) the highest rate permitted by applicable law.

                                    ARTICLE 5

thereof for any use or purpose contrary to the provisions of Exhibit D, attached
hereto, or in violation of the laws of the United States of America, the state
in which the Building is located, or the ordinances, regulations or requirements
of the local municipal or county governing body or other lawful authorities
having jurisdiction over the Building. Tenant shall comply with all recorded
covenants, conditions, and restrictions, and the provisions of all ground or
underlying leases, now or hereafter affecting the Real Property. Tenant shall
not use or allow another person or entity to use any part of the Premises for
the storage, use, treatment, manufacture or sale of "HAZARDOUS MATERIAL," as
that term is defined below. As used herein, the term "HAZARDOUS


                                       8
<PAGE>   15
MATERIAL" means any hazardous or toxic substance, material or waste which is or
becomes regulated by any local governmental authority, the state in which the
Building is located or the United States Government.

6.1.2 below.

               6.1.2 Electricity for the Premises shall be provided through the
electrical wiring and facilities existing in the Premises as of the date of this

Improvements to be constructed pursuant to the Work Letter attached to this
Lease as Exhibit B); provided, however, that in no event shall the amount of the
electricity provided to and/or consumed in the Premises exceed the capacity of
such wiring and facilities. Tenant shall pay directly to Landlord, within ten
(10) days after demand and as additional rent under this Lease (and not as part
of Operating Expenses), the cost of electricity provided to and/or consumed in
the Premises (including the electricity for the heating and air conditioning
unit and normal and excess consumption), which electricity shall be separately
metered, at Tenant's cost. Such electricity shall be provided by a provider of
electricity which Landlord shall select in its sole discretion. At Landlord's
option, the cost of such electricity usage shall be billed directly by the
electricity provider to Tenant, and Tenant shall pay such costs to such provider
as and when due. Landlord shall bear the cost of replacement of Building
Standard lamps, starters and ballasts for lighting fixtures within the Premises

non-Building Standard lamps, starters and ballasts for lighting fixtures within
the Premises.

<PAGE>   16
        6.3 Interruption of Use. Except as otherwise provided in Section 6.5
below, Tenant agrees that Landlord shall not be liable for damages, by abatement
of Rent or otherwise, for failure to furnish or delay in furnishing any service
(including telephone and telecommunication services), or for any diminution in
the quality or quantity thereof, when such failure or delay or diminution is
occasioned, in whole or in part, by repairs, replacements, or improvements, by
any strike, lockout or other labor trouble, by inability to secure electricity,
gas, water, or other fuel at the Building after reasonable effort to do so, by
any accident or casualty whatsoever, by act or default of Tenant or other
parties, or by any other cause beyond Landlord's reasonable control; and such
failures or delays or diminution shall never be deemed to constitute an eviction
or disturbance of Tenant's use and possession of the Premises or relieve Tenant
from paying Rent or performing any of its obligations under this Lease.
Furthermore, Landlord shall not be liable under any circumstances for a loss of,
or injury to, property or for injury to, or interference with, Tenant's
business, including, without limitation, loss of profits, however occurring,
through or in connection with or incidental to a failure to furnish any of the
services or utilities as set forth in this Article 6.

        6.4 Additional Services. Landlord shall also have the exclusive right,
but not the obligation, to provide any additional services which may be required
by Tenant, including, without limitation, locksmithing, lamp replacement,
additional janitorial service, and additional repairs and maintenance, provided
that Tenant shall pay to Landlord upon billing, the sum of all costs to Landlord
of such additional services plus an administration fee. Charges for any
utilities or service for which Tenant is required to pay from time to time
hereunder, shall be deemed Additional Rent hereunder and shall be billed on a
monthly basis.

        6.5 Abatement of Rent. Notwithstanding the provisions of Section 6.3
above to the contrary, in the event that during this Lease Term Tenant is
prevented from using, and does not use, the Premises or any portion thereof as a
result of the failure by Landlord to provide the electricity to the Premises
required to be provided by Landlord pursuant to Section 6.1.2 above, and such
failure is not the result of (i) the negligence or willful misconduct of Tenant
or any of Tenant's employees, agents, contractors, licensees or invitees, or
(ii) any strike, lockout or other labor trouble, any inability to secure
utilities at the Building after reasonable effort to do so, any accident or
casualty whatsoever, or any other cause beyond Landlord's reasonable control
(such event shall be known as an "ABATEMENT EVENT"), then Tenant shall give
Landlord written notice of such Abatement Event. If such Abatement Event
continues for ten (10) consecutive days after Landlord's receipt of any such
written notice from Tenant ("ELIGIBILITY PERIOD"), then the Rent shall be abated
or reduced, as the case may be, during such time after the Eligibility Period
that Tenant continues to be so prevented from using, and does not use, the
Premises or a portion thereof, in the proportion that the rentable square feet
of the portion of the Premises that Tenant is prevented from using, and does not
use, bears to the total rentable square feet of the Premises. The foregoing
provisions of this Section 6.5 shall not apply to any abatement of Rent that may
be available to Tenant following a damage or destruction or eminent domain
taking as provided in Articles 11 and 12 of this Lease, and accordingly, to the
extent Tenant is entitled to abatement without regard to the Eligibility Period
because of a damage, destruction or eminent domain taking pursuant to Articles
11 and 12 of this Lease, then the Eligibility Period shall not be applicable to
such event.

however, if such maintenance and repairs are caused in part or in whole by the
act. neglect. fault of or omission of any duty by Tenant, its agents, servants,
employees or invitees, Tenant shall pay to Landlord as additional rent. the
reasonable cost of such maintenance and repairs. Landlord shall not be liable
for any failure to make ally such repairs, or to perform any maintenance unless
such failure shall persist for an unreasonable time after written notice of the
need of such repairs or maintenance is given to Landlord by Tenant. There shall
be no abatement of rent and no liability of Landlord by reason of any injury to
or interference with Tenant's business arising from the making of any repairs,
alterations or improvements in or to any portion of the Building or the Premises
or in or to fixtures, appurtenances and equipment therein. Tenant hereby waives

the "ALTERATIONS") without first procuring the prior written consent of Landlord
to such Alterations, which consent shall be requested by Tenant not less than
thirty (30) days prior to the commencement thereof, and which consent shall not
be unreasonably withheld by Landlord; provided, however, Landlord may withhold
its consent in its sole and absolute discretion with respect to any Alterations
which may affect the structural components of the Building or the Systems and
Equipment. Tenant shall pay for all overhead, general conditions, fees and other
costs and expenses of the Alterations, and


                                       11
<PAGE>   18
shall pay to Landlord a Landlord supervision fee of five percent (5%) of the
cost of the Alterations. The construction of the initial improvements to the
Premises shall be governed by the terms of the Tenant Work Letter and not the
terms of this Article 8. Notwithstanding anything to the contrary set forth in
this Article 8, Landlord's approval shall not be required for the movement of
telecommunications racks within the Premises and the installation of
telecommunications wiring provided that such movement and installation do not
affect the structural components of the Building or the Systems and Equipment.
In connection with Tenant's normal business operations, Tenant anticipates that
it will need to install wiring between the Premises and the streets surrounding
the Building in order for Tenant to connect Tenant's telecommunications
equipment to other telecommunications systems. Provided that Tenant shall comply
with all applicable laws, Landlord's Rules and Regulations and such activities
do not interfere with the structural components of the Building or the Systems
and Equipment, Tenant shall have the right to install such wiring.

        8.2 Manner of Construction. Landlord may impose, as a condition of its
consent to all Alterations or repairs of the Premises or about the Premises,
such requirements as Landlord in its reasonable discretion may deem desirable,
including, but not limited to, the requirement that Tenant utilize for such
purposes only contractors, materials, mechanics and materialmen approved by
Landlord; provided, however, Landlord may impose such requirements as Landlord
may determine, in its sole and absolute discretion, with respect to any work
affecting the structural components of the Building or Systems and Equipment
(including designating specific contractors to perform such work). Tenant shall
construct such Alterations and perform such repairs in conformance with any and
all applicable rules and regulations of any federal, state, county or municipal
code or ordinance and pursuant to a valid building permit, issued by the city in
which the Building is located, and in conformance with Landlord's construction
rules and regulations. Landlord's approval of the plans, specifications and
working drawings for Tenant's Alterations shall create no responsibility or
liability on the part of Landlord for their completeness, design sufficiency, or
compliance with all laws, rules and regulations of governmental agencies or
authorities. All work with respect to any Alterations must be done in a good and
workmanlike manner and diligently prosecuted to completion to the end that the
Premises shall at all times be a complete unit except during the period of work.
In performing the work of any such Alterations, Tenant shall have the work
performed in such manner as not to obstruct access to the Building or the common
areas for any other tenant of the Building, and as not to obstruct the business
of Landlord or other tenants in the Building, or interfere with the labor force
working in the Building. If Tenant makes any Alterations, Tenant agrees to carry
"BUILDER'S ALL RISK" insurance in an amount approved by Landlord covering the
construction of such Alterations, and such other insurance as Landlord may
require, it being understood and agreed that all of such Alterations shall be
insured by Tenant pursuant to Article 10 of this Lease immediately upon
completion thereof In addition, Landlord may, in its discretion, require Tenant
to obtain a lien and completion bond or some alternate form of security
satisfactory to Landlord in an amount sufficient to ensure the lien-free
completion of such Alterations and naming Landlord as a co-obligee. Upon
completion of any Alterations, Tenant shall (i) cause a Notice of Completion to
be recorded in the office of the Recorder of the county in which the Building is
located in accordance with Section 3093 of the Civil Code of the State of
California or any successor statute, (ii) deliver to the Building management
office a reproducible copy of


                                       12
<PAGE>   19
the "as built" drawings of the Alterations, and (iii) deliver to Landlord
evidence of payment, contractors' affidavits and full and final waivers of all
liens for labor, services or materials.

        8.3 Landlord's Property. All Alterations, improvements, fixtures and/or
equipment which may be installed or placed in or about the Premises, and all
signs installed in, on or about the Premises, from time to time, shall be at the
sole cost of Tenant and shall be and become the property of Landlord; provided,
however, that any communications and communications-related equipment installed
by Tenant in the Premises shall remain the property of Tenant and Tenant shall,
at its expense, remove such equipment at the expiration or earlier termination
of the Lease Term, and repair any damage to the Premises and Building caused by
such removal. In addition, Tenant shall, at its expense, remove the raised floor
which is in the Premises as of tile date of the execution of this Lease at the
expiration or earlier termination of the Lease Term, and repair any damage to
the Building caused by such removal. Furthermore, Landlord may require that
Tenant, at its expense, remove any other improvement or Alteration upon the
expiration or early termination of the Lease Term, and repair any damage to the
Premises and Building caused by such removal. If Tenant fails to complete any
such removal and/or to repair any damage caused by the removal of any
Alterations. Landlord may do so and may charge the cost thereof to Tenant.

                                    ARTICLE 9

                             COVENANT AGAINST LIENS

        Tenant has no authority or power to cause or permit any lien or
encumbrance of any kind whatsoever, whether created by act of Tenant, operation
of law or otherwise, to attach to or be placed upon the Real Property, Building
or Premises, and any and all liens and encumbrances created by Tenant shall
attach to Tenant's interest only. Landlord shall have the right at all times to
post and keep posted on the Premises any notice which it deems necessary for
protection from such liens. Tenant covenants and agrees not to suffer or permit
any lien of mechanics or materialmen or others to be placed against the Real
Property, the Building or the Premises with respect to work or services claimed
to have been performed for or materials claimed to have been furnished to Tenant
or the Premises, and, in case of any such lien attaching or notice of any lien,
Tenant covenants and agrees to cause it to be immediately released and removed
of record. Notwithstanding anything to the contrary set forth in this Lease, if
any such lien is not released and removed on or before the date notice of such
lien is delivered by Landlord to Tenant, Landlord, at its sole option, may
immediately take all action necessary to release and remove such lien, without
any duty to investigate the validity thereof, and all sums, costs and expenses,
including reasonable attorneys' fees and costs, incurred by Landlord in
connection with such lien shall be deemed Additional Rent under this Lease and
shall immediately be due and payable by Tenant.

notify Landlord of any damage to the Premises resulting from fire or any other
casualty. If the Premises or any common areas of the Building serving or

condition; provided that if the cost of such repair by Landlord exceeds the
amount of insurance proceeds received by Landlord from Tenant's insurance
carrier, as assigned by Tenant, the cost of such repairs shall be paid by Tenant
to Landlord prior to Landlord's repair of the damage. In connection with such
repairs and replacements, Tenant shall, prior to the commencement of
construction, submit to Landlord, for Landlord's review and approval, all plans,
specifications and working drawings relating thereto, and Landlord shall select
the contractors to perform such improvement work. Landlord shall not be liable

employees, contractors, licensees, or invitees, Landlord shall allow Tenant a
proportionate abatement of Base Rent and Tenant's Share of Direct Expenses to
the extent Landlord is reimbursed from the proceeds of rental interruption
insurance purchased by Landlord as part of Operating Expenses, during the time
and to the extent the Premises are unfit for occupancy for the purposes
permitted under this Lease, and not occupied by Tenant as a result thereof.

        11.2 Landlord's Option to Repair. Notwithstanding the terms of Section

<PAGE>   23

Building shall require that the insurance proceeds or any portion thereof be
used to retire the mortgage debt, or shall terminate the ground or underlying
lease, as the case may be; or (iii) the damage is not fully covered, except for
deductible amounts, by Landlord's insurance policies. In addition, if the
Premises or the Building is destroyed or damaged to an' substantial extent
during the last twelve (12) months of the Lease Term, then notwithstanding
anything contained in this Article 11, Landlord shall have the option to
terminate this Lease by giving written notice to Tenant of the exercise of such
option within thirty (30) days after such damage or destruction, in which event
this Lease shall cease and terminate as of the date of such notice. Upon any
such termination of this Lease pursuant to this Section 11.2, Tenant shall pay
the Base Rent and Additional Rent, properly apportioned up to such date of
termination, and both parties hereto shall thereafter be freed and discharged of
all further obligations hereunder, except as provided for in provisions of this
Lease which by their terms survive the expiration or earlier termination of the
Lease Term.

        11.3 Waiver of Statutory Provisions. The provisions of this Lease,
including this Article 11, constitute an express agreement between Landlord and

statute or regulation of the state in which the Building is located. including,
without limitation, Sections 1932(2) and 1933(4) of the California Civil Code,
with respect to any rights or obligations concerning damage or destruction in

                                  CONDEMNATION

        12.1 Permanent Taking. If the whole or any part of the Premises or
Building shall be taken by power of eminent domain or condemned by any competent
authority for any public or quasi-public use or purpose, or if any adjacent
property or street shall be so taken or condemned, or reconfigured or vacated by
such authority in such manner as to require the use, reconstruction or
remodeling of any part of the Premises or Building, or if Landlord shall grant a
deed or other instrument in lieu of such taking by eminent domain or
condemnation, Landlord shall have the option to terminate this Lease upon ninety
(90) days' notice, provided such notice is given no later than one hundred
eighty (180) days after the date of such taking, condemnation, reconfiguration,
vacation, deed or other instrument. If more than twenty-five percent (25%) of
the rentable square feet of the Premises is taken, or if access to the Premises
is substantially impaired, Tenant shall have the option to terminate this Lease
upon ninety (90) days' notice,


                                       17
<PAGE>   24
provided such notice is given no later than one hundred eighty (180) days after
the date of such taking. Landlord shall be entitled to receive the entire award
or payment in connection therewith, except that Tenant shall have the right to
file any separate claim available to Tenant for any taking of Tenant's personal
property and fixtures belonging to Tenant and removable by Tenant upon
expiration of the Lease Term pursuant to the terms of this Lease, and for moving
expenses, so long as such claim does not diminish the award available to
Landlord, its ground lessor with respect to the Real Property or its mortgagee,
and such claim is payable separately to Tenant. All Rent shall be apportioned as
of the date of such termination, or the date of such taking, whichever shall
first occur. If any part of the Premises shall be taken, and this Lease shall
not be so terminated, the Rent shall be proportionately abated. Tenant hereby
waives any and all rights it might otherwise have pursuant to Section 1265.130
of The California Code of Civil Procedure.

        12.2 Temporary Taking. Notwithstanding anything to the contrary
contained in this Article 12, in the event of a temporary taking of all or any
portion of the Premises for a period of one hundred and eighty (180) days or
less, then this Lease shall not terminate but the Base Rent and the Additional
Rent shall be abated for the period of such taking in proportion to the ratio
that the amount of rentable square feet of the Premises taken bears to the total
rentable square feet of the Premises. Landlord shall be entitled to receive the
entire award made in connection with any such temporary taking.

                                   ARTICLE 14

                            ASSIGNMENT AND SUBLETTING

        14.1 Transfers. Subject to Tenant's rights set forth in Section 14.7

otherwise transfer, this Lease or any interest hereunder, permit any assignment
or other such foregoing transfer of this Lease or any interest hereunder by
operation of law, sublet the Premises or any part thereof, or permit the use of
the Premises by any persons other than Tenant and its employees (all of the
foregoing are hereinafter sometimes referred to collectively as "TRANSFERS" and
any person to whom any Transfer is made or sought to be made is hereinafter
sometimes referred to as a "TRANSFEREE"). If Tenant shall desire Landlord's
consent to any Transfer, Tenant shall notify Landlord in writing, which notice


                                       18
<PAGE>   25
(the "TRANSFER NOTICE") shall include (i) the proposed effective date of the
Transfer, which shall not be less than thirty (30) days nor more than one
hundred eighty (180) days after the date of delivery of the Transfer Notice,
(ii) a description of the portion of the Premises to be transferred (the
"SUBJECT SPACE"), (iii) all of the terms of the proposed Transfer, the name and
address of the proposed Transferee, and a copy of all existing and/or proposed
documentation pertaining to the proposed Transfer, including all existing
operative documents to be executed to evidence such Transfer or the agreements
incidental or related to such Transfer, (iv) current financial statements of the
proposed Transferee certified by an officer, partner or owner thereof,, and (v)
such other information as Landlord ma', reasonably require. Any Transfer made
without Landlord's prior written consent shall, at Landlord's option, be null,
void and of no effect, and shall, at Landlord's option, constitute a default by
Tenant under this Lease. Whether or not Landlord shall grant consent, Tenant
shall pay Landlord's reasonable legal fees incurred by Landlord, within thirty
(30) days after written request ~ Landlord. Notwithstanding anything to the
contrary set forth in this Article 14, Tenant shall have the right to rent rack
space to Tenant's customers, provided that such rental of rack space is made in
the ordinary course of the conduct of Tenant's business, and such rental shall
be deemed not to be a Transfer, and the terms and conditions of this Article 14
shall not apply to such rental.

        14.2 Landlord's Consent. Landlord shall not unreasonably withhold its
consent to any proposed Transfer of the Subject Space to the Transferee on the
terms specified in the Transfer Notice. The parties hereby agree that it shall
be reasonable under this Lease and under any applicable law for Landlord to
withhold consent to any proposed Transfer where one or more of the following
apply, without limitation as to other reasonable grounds for withholding
consent:

               14.2.1 The Transferee is of a character or reputation or engaged
in a business which is not consistent with the quality of the Building;

               14.2.2 The Transferee intends to use the Subject Space for
purposes which are not permitted under this Lease;

               14.2.3 The Transferee is either a governmental agency or
instrumentality thereof,

               14.2.4 The Transfer will result in more than a reasonable and
safe number of occupants per floor within the Subject Space;

               14.2.5 The Transferee is not a party of reasonable financial
worth and/or financial stability in light of the responsibilities involved under
the Lease on the date consent is requested;

               14.2.6 The proposed Transfer would cause Landlord to be in
violation of another lease or agreement to which Landlord is a party, or would
give an occupant of the Building a right to cancel its lease;

               14.2.7 The terms of the proposed Transfer will allow the
Transferee to exercise a right of renewal, right of expansion, right of first
offer, or other similar right held by Tenant (or will allow the Transferee to
occupy space leased by Tenant pursuant to any such right); or


                                       19
<PAGE>   26
               14.2.8 Either the proposed Transferee, or any person or entity
which directly or indirectly, controls, is controlled by, or is under common
control with, the proposed Transferee, (i) occupies space in the Building at the
time of the request for consent, (ii) is negotiating with Landlord to lease
space in the Building at such time, or (iii) has negotiated with Landlord during
the twelve (12)-month period immediately preceding the Transfer Notice.

        If Landlord consents to any Transfer pursuant to the terms of this
Section 14.2 (and does not exercise any recapture rights Landlord may have under
Section 14.4 of this Lease), Tenant may within six (6) months after Landlord's
consent, but not later than the expiration of said six-month period, enter into
such Transfer of the Premises or portion thereof. upon substantially the same
terms and conditions as are set forth in the Transfer Notice furnished by Tenant
to Landlord pursuant to Section 14.1 of this Lease, provided that if there are
any changes in the terms and conditions from those specified in the Transfer
Notice (i) such that Landlord would initially have been entitled to refuse its
consent to such Transfer under this Section 14.2, or (ii) which would cause the
proposed Transfer to be more favorable to the Transferee than the terms set
forth in Tenant's original Transfer Notice, Tenant shall again submit the
Transfer to Landlord for its approval and other action under this Article 14
(including Landlord's right of recapture, if any, under Section 14.4 of this
Lease).

        14.3 Transfer Premium. If Landlord consents to a Transfer, as a
condition thereto which the parties hereby agree is reasonable, Tenant shall pay
to Landlord seventy-five percent (75%) of any "TRANSFER PREMIUM," as that term
is defined in this Section 14.3, received by Tenant from such Transferee.
"TRANSFER PREMIUM" shall mean all rent, additional rent or other consideration
payable by such Transferee in excess of the Rent and Additional Rent payable by
Tenant under this Lease on a per rentable square foot basis if less than all of
the Premises is transferred, after deducting the reasonable expenses incurred by
Tenant for (i) any changes, alterations and improvements to the Premises in
connection with the Transfer, and (ii) any brokerage commissions in connection
with the Transfer (collectively, the "SUBLEASING COSTS"). "TRANSFER PREMIUM"
shall also include, but not be limited to, key money and bonus money paid by
Transferee to Tenant in connection with such Transfer, and any payment in excess
of fair market value for services rendered by Tenant to Transferee or for
assets, fixtures, inventory, equipment, or furniture transferred by Tenant to
Transferee in connection with such Transfer.

        14.4 Landlord's Option as to Subject Space. Subject to the terms of
Section 14.7 below, notwithstanding anything to the contrary contained in this
Article 14, Landlord shall have the option, by giving written notice to Tenant
within thirty (30) days after receipt of any Transfer Notice, to recapture the
Subject Space. Such recapture notice shall cancel and terminate this Lease with
respect to the Subject Space as of the date stated in the Transfer Notice as the
effective date of the proposed Transfer until the last day of the term of the
Transfer as set forth in the Transfer Notice. If this Lease shall be canceled
with respect to less than the entire Premises, the Rent reserved herein shall be
prorated on the basis of the number of rentable square feet retained by Tenant
in proportion to the number of rentable square feet contained in the Premises,
and this Lease as so amended shall continue thereafter in full force and effect,
and upon request of either party, the parties shall execute written confirmation
of the same. If Landlord declines, or fails to elect in a timely manner to
recapture the Subject Space under this Section 14.4, then,


                                       20
<PAGE>   27
provided Landlord has consented to the proposed Transfer, Tenant shall be
entitled to proceed to transfer the Subject Space to the proposed Transferee.
subject to provisions of the last paragraph of Section 14.2 of this Lease.
Notwithstanding anything to the contrary set forth in this Section 14.4,
Landlord shall not have the rights provided to Landlord under this Section 14.4
for the first three (3) years of the Lease Term only.

        14.5 Effect of Transfer. If Landlord consents to a Transfer, (i) the
terms and conditions of this Lease shall in no way be deemed to have been waived
or modified, (ii) such consent shall not be deemed consent to any further
Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to
Landlord, promptly after execution, an original executed copy of all
documentation pertaining to the Transfer in form reasonably acceptable to
Landlord, and (iv) no Transfer relating to this Lease or agreement entered into
with respect thereto, whether with or without Landlord's consent, shall relieve
Tenant or any guarantor of the Lease from liability under this Lease. Landlord
or its authorized representatives shall have the right at all reasonable times
to audit the books, records and papers of Tenant relating to any Transfer, and
shall have the right to make copies thereof. If the Transfer Premium respecting
any Transfer shall be found understated, Tenant shall, within thirty (30) days
after demand, pay the deficiency and Landlord's costs of such audit.

        14.6 Additional Transfers. Subject to Section 14.7 below, for purposes
of this Lease, the term "TRANSFER" shall also include (i) if Tenant is a
partnership, the withdrawal or change, voluntary, involuntary or by operation of
law, of fifty percent (50%) or more of the partners, or transfer of twenty-five
percent or more of partnership interests, within a twelve (12)-month period, or
the dissolution of the partnership without immediate reconstitution thereof, and
(ii) if Tenant is a closely held corporation (i.e., whose stock is not publicly
held and not traded through an exchange or over the counter), (A) the
dissolution, merger, consolidation or other reorganization of Tenant, (B) the
sale or other transfer of more than an aggregate of fifty percent (50%) of the
voting shares of Tenant (other than to immediate family members by reason of
gift or death), within a twelve (12)-month period, or (C) the sale, mortgage,
hypothecation or pledge of more than an aggregate of fifty percent (50%) of the
value of the unencumbered assets of Tenant within a twelve (12) month period.

        14.7 Non-Transfers. Notwithstanding the foregoing provisions of this
Article 14 to the contrary, neither (i) an assignment to a transferee of all or
substantially all of the assets of Tenant, (ii) an assignment of this Lease to a
transferee which is the resulting entity of a merger or consolidation of Tenant
with another entity, nor (iii) an assignment of this Lease or subletting of all
or a portion of the Premises to an affiliate of Tenant (an entity which is
controlled by, controls, or is under common control with, Tenant) shall be
deemed a Transfer under Section 14.1 above, provided that (A) Tenant notifies
Landlord of any such assignment or sublease and promptly supplies Landlord with
any documents or information reasonably requested by Landlord regarding such
transfer or transferee as set forth in items (i) through (v) of Section 14.1
above, (B) such assignment or sublease is not a subterfuge by Tenant to avoid
its obligations under this Lease, and (C) such transferee or affiliate (referred
to in hits Lease as the "PERMITTED AFFILIATE") shall have a net worth (not
including goodwill as an asset) computed in accordance with generally accepted
accounting principles (the "NET WORTH") at lease equal to the 


                                       21
<PAGE>   28
greater of (y) the Net Worth of Tenant immediately prior to such assignment or
sublease, or (z) the Net Worth on the date of execution of this Lease by the
original named Tenant. "Control," as used in this Section 14.7, shall mean the
ownership, directly or indirectly, of at least fifty-one percent (51%) of the
voting securities of, or possession of the right to vote, in the ordinary
direction of its affairs, of at least fifty-one percent (51%) of the voting
interest in, any person or entity.

                              SURRENDER; OWNERSHIP
                          AND REMOVAL OF TRADE FIXTURES

        15.1 Surrender of Premises. No act or thing done by Landlord or any
agent or employee of Landlord during the Lease Term shall be deemed to
constitute an acceptance by Landlord of a surrender of the Premises unless such
intent is specifically acknowledged in a writing signed by Landlord. The
delivery of keys to the Premises to Landlord or any agent or employee of
Landlord shall not constitute a surrender of the Premises or effect a
termination of this Lease, whether or not the keys are thereafter retained by
Landlord, and notwithstanding such delivery Tenant shall be entitled to the
return of such keys at any reasonable time upon request until this Lease shall
have been properly terminated. The voluntary or other surrender of this Lease by
Tenant, whether accepted by Landlord or not, or a mutual termination hereof,
shall not work a merger, and at the option of Landlord shall operate as an
assignment to Landlord of all subleases or subtenancies affecting the Premises.

        15.2 Removal of Tenant Property by Tenant. Upon the expiration of the
Lease Term, or upon any earlier termination of this Lease, Tenant shall, subject
to the provisions of this Article 15, quit and surrender possession of the
Premises to Landlord in as good order and condition as when Tenant took
possession and as thereafter improved by Landlord and/or Tenant, reasonable wear
and tear and repairs which are specifically made the responsibility of Landlord
hereunder excepted. Upon such expiration or termination, Tenant shall, without
expense to Landlord, remove or cause to be removed from the Premises all debris
and rubbish, and such items of furniture, equipment, free-standing cabinet work,
and other articles of personal property owned by Tenant or installed or placed
by Tenant at its expense in the Premises, and such similar articles of any other
persons claiming under Tenant, as Landlord may, in its sole discretion, require
to be removed, and Tenant shall repair at its own expense all damage to the
Premises and Building resulting from such removal.

                                   ARTICLE 16

                                  HOLDING OVER

        If Tenant holds over after the expiration of the Lease Term hereof, with
or without the express or implied consent of Landlord, such tenancy shall be
from month-to-month only, and shall not constitute a renewal hereof or an
extension for any further term, and in such case Base Rent shall be payable at a
monthly rate equal to two hundred percent (200%) of the greater of (i) the Base
Rent applicable during the last rental period of the Lease Term under this Lease
or (ii) 


                                       22
<PAGE>   29
the fair market rental rate for the Premises as of the commencement of such
holdover period. Such month-to-month tenancy shall be subject to every other
term, covenant and agreement contained herein. Landlord hereby expressly
reserves the right to require Tenant to surrender possession of the Premises to
Landlord as provided in this Lease upon the expiration or other termination of
this Lease. The provisions of this Article 16 shall not be deemed to limit or
constitute a waiver of any other rights or remedies of Landlord provided herein
or at law. If Tenant fails to surrender the Premises upon the termination or
expiration of this Lease, in addition to any other liabilities to Landlord
accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord
harmless from all loss, costs (including reasonable attorneys' fees) and
liability resulting from such failure, including, without limiting the
generality of the foregoing, any claims made by any succeeding tenant founded
upon such failure to surrender, and any lost profits to Landlord resulting
therefrom.

                                   ARTICLE 17

                              ESTOPPEL CERTIFICATES

        Within ten (10) days following a request in writing by Landlord, Tenant
shall execute and deliver to Landlord an estoppel certificate, which, as
submitted by Landlord, shall be substantially in the form of Exhibit E, attached
hereto, (or such other form as may be required by any prospective mortgagee or
purchaser of the Project, or any portion thereof,, indicating therein any
exceptions thereto that may exist at that time, and shall also contain any other
information reasonably requested by Landlord or Landlord's mortgagee or
prospective mortgagee. Tenant shall execute and deliver whatever other
instruments may be reasonably required for such purposes. Failure of Tenant to
timely execute and deliver such estoppel certificate or other instruments shall
constitute an acceptance of the Premises and an acknowledgment by Tenant that
statements included in the estoppel certificate are true and correct, without
exception.

                                   ARTICLE 18

                                  SUBORDINATION

        18.1 Subordination. This Lease is subject and subordinate to all present
and future ground or underlying leases of the Real Property and to the lien of
any mortgages or trust deeds, now or hereafter in force against the Real
Property and the Building, if any, and to all renewals, extensions,
modifications, consolidations and replacements thereof, and to all advances made
or hereafter to be made upon the security of such mortgages or trust deeds,
unless the holders of such mortgages or trust deeds, or the lessors under such
ground lease or underlying leases, require in writing that this Lease be
superior thereto. Tenant covenants and agrees in the event any proceedings are
brought for the foreclosure of any such mortgage, or if any ground or underlying
lease is terminated, to attorn, without any deductions or set-offs whatsoever,
to the purchaser upon any such foreclosure sale, or to the lessor of such ground
or underlying lease, as the case may be, if so requested to do so by such
purchaser or lessor and/or if required to do so pursuant to any subordination,
nondisturbance and attornment agreement executed pursuant to Section 8.2 below,
and to recognize such purchaser or lessor as the lessor under this Lease. Tenant
shall, within five (5) days of request by Landlord, execute such further
instruments or 


                                       23
<PAGE>   30
assurances as Landlord may reasonably deem necessary to evidence or confirm the
subordination or superiority of this Lease to any such mortgages, trust deeds,
ground leases or underlying leases. Tenant hereby irrevocably authorizes
Landlord to execute and deliver in the name of Tenant any such instrument or
instruments if Tenant fails to do so, provided that such authorization shall in
no way relieve Tenant from the obligation of executing such instruments of
subordination or superiority. Tenant waives the provisions of any current or
future statute, rule or law which may give or purport to give Tenant any right
or election to terminate or otherwise adversely affect this Lease and the
obligations of the Tenant hereunder in the event of any foreclosure proceeding
or sale.

        18.2 Existing Agreement. Tenant hereby acknowledges that as of the date
on which Landlord and Tenant execute this Lease there is a deed of trust
encumbering, and in force against, the Real Property in favor of General
Electric Capital Corporation, a New York corporation (the "CURRENT LENDER").
Simultaneously with Tenant's execution of this Lease, Tenant shall sign,
notarize and deliver a subordination, non-disturbance and attornment agreement
substantially in the form of Exhibit G attached hereto. If Landlord at any time
during the Lease Term causes the Real Property to be encumbered by a new deed of
trust or mortgage pursuant to which the beneficiary of such deed of trust or
mortgage is a party or entity other than the Current Lender, and/or if any party
which acquires, or otherwise succeeds to, Landlord's interest in the Real
Property (including without limitation, any ground lessee) encumbers or places a
lien against the Real Property with a mortgage, deed of trust or similar
security instrument and the beneficiary thereof requires this Lease to be
subordinated to such encumbrance or lien, Landlord or the successor of Landlord
will use commercially reasonable efforts to provide to Tenant a subordination,
nondisturbance and attornment agreement in form reasonably acceptable to
Landlord or such successor of Landlord, the subject beneficiary and Tenant. If
said subordination, non-disturbance and attornment agreement is required and
agreed upon by the aforesaid parties, Landlord or the successor of Landlord, the
subject beneficiary and Tenant shall cause any such subordination,
non-disturbance and attornment agreement to be executed, acknowledged and
recorded concurrently with, or as soon as practicable after, the execution and
recordation of any such lien, deed of trust or mortgage. In addition to the
foregoing, if Landlord enters into a ground lease with regard to the Real
Property and such ground lessee requires this Lease to be subordinated to such
ground lease, the ground lessee and ground lessor will use commercially
reasonable efforts to provide to Tenant a subordination, non-disturbance and
attornment agreement in form reasonably acceptable to such ground lessee, ground
lessor, any beneficiary of ground lessee, and to Tenant.

                     TENANT'S DEFAULTS; LANDLORD'S REMEDIES

        19.1 Events of Default by Tenant. All covenants and agreements to be
kept or performed by Tenant under this Lease shall be performed by Tenant at
Tenant's sole cost and expense and without any reduction of Rent. The occurrence
of any of the following shall constitute a default of this Lease by Tenant:


                                       24
<PAGE>   31
               19.1.1 Any failure by Tenant to pay any Rent or any other charge
required to be paid under this Lease, or any part thereof, when due; or

               19.1.2 Any failure by Tenant to observe or perform any other
provision, covenant or condition of this Lease to be observed or performed by
Tenant where such failure continues for fifteen (15) days after written notice
thereof from Landlord to Tenant; provided however, that any such notice shall be
in lieu of, and not in addition to, any notice required under California Code of
Civil Procedure Section 1161 or any similar or successor law; and provided
further that if the nature of such default is such that the same cannot
reasonably be cured within a fifteen (1 5)-day period, Tenant shall not be
deemed to be in default if it diligently commences such cure within such period
and thereafter diligently proceeds to rectify' and cure said default as soon as
possible; or

               19.1.3 Abandonment or vacation of the Premises by Tenant.
Abandonment is herein defined to include, but is not limited to, any absence by
Tenant from the Premises for three (3) business days or longer while in default
of any provision of this Lease.

        19.2 Landlord's Remedies Upon Default. Upon the occurrence of any such
default by Tenant, Landlord shall have, in addition to any other remedies
available to Landlord at law or in equity, the option to pursue any one or more
of the following remedies, each and all of which shall be cumulative and
nonexclusive, without any notice or demand whatsoever.

               19.2.1 Terminate this Lease, in which event Tenant shall
immediately surrender the Premises to Landlord, and if Tenant fails to do so,
Landlord may, without prejudice to any other remedy which it may have for
possession or arrearages in rent, enter upon and take possession of the Premises
and expel or remove Tenant and any other person who may be occupying the
Premises or any part thereof, without being liable for prosecution or any claim
or damages therefor; and Landlord may recover from Tenant the following:

                      (i) The worth at the time of award of any unpaid rent
which has been earned at the time of such termination; plus

                      (ii) The worth at the time of award of the amount by which
the unpaid rent which would have been earned after termination until the time of
award exceeds the amount of such rental loss that Tenant proves could have been
reasonably avoided; plus

                      (iii) The worth at the time of award of the amount by
which the unpaid rent for the balance of the Lease Term after the time of award
exceeds the amount of such rental loss that Tenant proves could have been
reasonably avoided; plus

                      (iv) Any other amount necessary to compensate Landlord for
all the detriment proximately caused by Tenant's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, specifically including but not limited to, brokerage
commissions and advertising expenses incurred, expenses of remodeling the
Premises or any portion thereof for a new tenant, whether for the same or a
different use, and any special concessions made to obtain a new tenant; and


                                       25
<PAGE>   32

                      (v) At Landlord's election, such other amounts in addition
to or in lieu of the foregoing as may be permitted from time to time by
applicable law

The term "rent" as used in this Section 19.2 shall be deemed to be and to mean
all sums of every nature required to be paid by Tenant pursuant to the terms of
this Lease, whether to Landlord or to others. As used in Paragraphs 19.2.1(i)
and (ii), above, the "worth at the time of award" shall be computed by allowing
interest at the Interest Rate set forth in Section 4.5 of this Lease. As used in
Paragraph 19.2. 1(iii) above, the "worth at the time of award" shall be computed
by discounting such amount at the discount rate of the Federal Reserve Bank of
San Francisco at the time of award plus one percent (1%).

               19.2.2 Landlord shall have the remedy described in California
Civil Code Section 1951.4 (lessor may continue lease in effect after lessee's
breach and abandonment and recover rent as it becomes due, if lessee has the
right to sublet or assign, subject only to reasonable limitations). Accordingly,
if Landlord does not elect to terminate this Lease on account of any default by
Tenant, Landlord may, from time to time, without terminating this Lease, enforce
all of its rights and remedies under this Lease, including the right to recover
all rent as it becomes due.

               19.2.3 Landlord may, but shall not be obligated to, make any such
payment or perform or otherwise cure any such obligation, provision, covenant or
condition on Tenant's part to be observed or performed (and may enter the
Premises for such purposes). In the event of Tenant's failure to perform any of
its obligations or covenants under this Lease, and such failure to perform poses
a material risk of injury or harm to persons or damage to or loss of property,
then Landlord shall have the right to cure or otherwise perform such covenant or
obligation at any time after such failure to perform by Tenant, whether or not
any such notice or cure period set forth in Section 19.1 above has expired. Any
such actions undertaken by Landlord pursuant to the foregoing provisions of this
Section 19.2.3 shall not be deemed a waiver of Landlord's rights and remedies as
a result of Tenant's failure to perform and shall not release Tenant from any of
its obligations under this Lease.

        19.3 Payment by Tenant. Tenant shall pay to Landlord, within fifteen
(15) days after delivery by Landlord to Tenant of statements therefor: (i) sums
equal to expenditures reasonably made and obligations incurred by Landlord in
connection with Landlord's performance or cure of any of Tenant's obligations
pursuant to the provisions of Section 19.2.3 above; and (ii) sums equal to all
expenditures made and obligations incurred by Landlord in collecting or
attempting to collect the Rent or in enforcing or attempting to enforce any
rights of Landlord under this Lease or pursuant to law, including, without
limitation, all legal fees and other amounts so expended. Tenant's obligations
under this Section 19.3 shall survive the expiration or sooner termination of
the Lease Term.

        19.4 Sublessees of Tenant. Whether or not Landlord elects to terminate
this Lease on account of any default by Tenant, as set forth in this Article 19,
Landlord shall have the right to terminate any and all subleases, licenses,
concessions or other consensual arrangements for possession entered into by
Tenant and affecting the Premises or may, in Landlord's sole


                                       26
<PAGE>   33
discretion, succeed to Tenant's interest in such subleases, licenses,
concessions or arrangements. In the event of Landlord's election to succeed to
Tenant's interest in any such subleases, licenses, concessions or arrangements,
Tenant shall, as of the date of notice by Landlord of such election. have no
further right to or interest in the rent or other consideration receivable
thereunder.

        19.5 Waiver of Default. No waiver by Landlord of any violation or breach
by Tenant of any of the terms, provisions and covenants herein contained shall
be deemed or construed to constitute a waiver of any other or later violation or
breach by Tenant of the same or any other of the terms, provisions, and
covenants herein contained. Forbearance by Landlord in enforcement of one or
more of the remedies herein provided upon a default by Tenant shall not be
deemed or construed to constitute a waiver of such default. The acceptance of
any Rent hereunder by Landlord following the occurrence of any default, whether
or not known to Landlord, shall not be deemed a waiver of any such default,
except only a default in the payment of the Rent so accepted.

        19.6 Efforts to Relet. For the purposes of this Article 19, Tenant's
right to possession shall not be deemed to have been terminated by efforts of
Landlord to relet the Premises, by its acts of maintenance or preservation with
respect to the Premises, or by appointment of a receiver to protect Landlord's
interests hereunder. The foregoing enumeration is not exhaustive, but merely
illustrative of acts which may be performed by Landlord without terminating
Tenant's right to possession.

                                   ARTICLE 20

                                SECURITY DEPOSIT

        Concurrent with Tenant's execution of this Lease, Tenant shall deposit
with Landlord a security deposit (the "SECURITY DEPOSIT") in the amount set
forth in Section 10 of the Summary. The Security Deposit shall be held by
Landlord as security for the faithful performance by Tenant of all the terms,
covenants, and conditions of this Lease to be kept and performed by Tenant
during the Lease Term. If Tenant defaults with respect to any provisions of this
Lease, including, but not limited to, the provisions relating to the payment of
Rent, Landlord may, but shall not be required to, use, apply or retain all or
any part of the Security Deposit for the payment of any Rent or any other sum in
default, or for the payment of any amount that Landlord may spend or become
obligated to spend by reason of Tenant's default, or to compensate Landlord for
any other loss or damage that Landlord may suffer by reason of Tenant's default.
If any portion of the Security Deposit is so used or applied, Tenant shall,
within five (5) days after written demand therefor, deposit cash with Landlord
in an amount sufficient to restore the Security Deposit to its original amount,
and Tenant's failure to do so shall be a default under this Lease. If Tenant
shall fully and faithfully perform every provision of this Lease to be performed
by it, the Security Deposit, or any balance thereof, shall be returned to
Tenant, or, at Landlord's option, to the last assignee of Tenant's interest
hereunder, within sixty (60) days following the expiration of the Lease Term.
Tenant shall not be entitled to any interest on the Security Deposit.

                               COMPLIANCE WITH LAW

        Tenant shall not do anything or suffer anything to be done in or about
the Premises which will in any way conflict with any law, statute, ordinance or
other governmental rule, regulation or requirement now in force or which may
hereafter be enacted or promulgated. At its sole cost and expense, Tenant shall
promptly comply with all such governmental measures, other than the making of
structural changes or changes to the Building's life safety system (collectively
the "EXCLUDED CHANGES") except to the extent such Excluded Changes are required
due to Tenant's alterations to or manner of use of the Premises. In addition,
Tenant shall fully comply with all present or future programs intended to manage
parking, transportation or traffic in and around the Building, and in connection
therewith, Tenant shall take responsible action for the transportation planning
and management of all employees located at the Premises by working directly with
Landlord, any governmental transportation management organization or any other
transportation-related committees or entities. The judgment of any court of
competent jurisdiction or the admission of Tenant in any judicial action,
regardless of whether Landlord is a party thereto, that Tenant has violated any
of said governmental measures, shall be conclusive of that fact as between
Landlord and Tenant.

                                   ARTICLE 22

                                ENTRY BY LANDLORD

        Landlord reserves the right at all reasonable times and upon at least
twenty-four hours' notice (except in the event of an emergency) to Tenant to
enter the Premises to (i) inspect them; (ii) show the Premises to prospective
purchasers, mortgagees or tenants; or to the ground or underlying lessors; (iii)
post notices of nonresponsibility; or (iv) alter, improve or repair the Premises
or the Building if necessary to comply with current building codes or other
applicable laws, or for structural alterations, repairs or improvements to the
Building, or as Landlord may otherwise reasonably desire or deem necessary.
Notwithstanding anything to the contrary contained in this Article 22, Landlord
may enter the Premises at any time, without notice to Tenant, to perform
janitorial or other services required of Landlord pursuant to this Lease. Any
such entries shall be without the abatement of Rent and shall include the right
to take such reasonable steps as required to accomplish the stated purposes.
Tenant hereby waives any claims for damages or for any injuries or inconvenience
to or interference with Tenant's business, lost profits, any loss of occupancy
or quiet enjoyment of the Premises, and any other loss occasioned thereby. For
each of the above purposes, Landlord shall at all times have a key with which to
unlock all the doors in the Premises, excluding Tenant's vaults, safes and
special security areas designated in advance by Tenant. In an emergency,
Landlord shall have the right to use any means that Landlord may deem proper to
open the doors in and to the Premises. Any entry into the Premises in the manner
hereinbefore described shall not be deemed to be a forcible or unlawful entry
into, or a detainer of, the Premises, or an actual or constructive eviction of
Tenant from any portion of the Premises.

four (4) copies signed by Tenant of such Final Working Drawings. Landlord shall
advise Tenant within five (5) business

accordance with such review and any disapproval of Landlord in connection
therewith.

Final Working Drawings, Tenant may submit the same to the appropriate
governmental authorities for all applicable building permits. Tenant hereby
agrees that neither Landlord nor Landlord's consultants shall be responsible for
obtaining any building permit or certificate of occupancy for the Premises and
that obtaining the same shall be Tenantts responsibility; provided, however,

costs, losses, damages, injuries and liabilities related in any way to
Landlord's performance of any ministerial acts reasonably necessary (i) to
permit Tenant to complete the Tenant Improvements, and (ii) to enable Tenant to
obtain any building permit or certificate of occupancy for the Premises.

inspect the Tenant Improvements at all times, provided however, that Landlord's
failure to inspect the Tenant Improvements shall in no event constitute a waiver
of any of Landlord's rights hereunder nor shall Landlord's inspection of the
Tenant Improvements constitute Landlord's approval of the same. Should Landlord
disapprove any portion of the Tenant Improvements, Landlord shall notify Tenant
in writing of such disapproval and shall specify the items disapproved. Any
defects or deviations in, and/or disapproval by Landlord of, the Tenant
Improvements shall be rectified by Tenant at no expense to Landlord, provided

                              ASBESTOS NOTIFICATION
                         100 CALIFORNIA STREET BUILDING

        The California legislature adopted Assembly Bill 3713 (effective January
1, 1989) which requires, among other things, that a building owner inform
tenants, employees and contractors if the building owner has knowledge of the
presence of asbestos containing materials (ACMs) in the building. In the
California statutes an ACM is defined as a construction material containing
"more than one-tenth of one percent asbestos by weight."

        Annually the building sends a letter to the building's tenants,
employees and contractors disclosing the presence of ACMs known to the owner.
All of the buildings consultant's reports are available for review in the
Building Office, 100 California Street, Suite 770, San Francisco, California.

        During the month of April, 1994 a survey of the building was conducted
by Boelter Environmental Consultants. The survey concludes that during the
original building construction, two layers of materials were applied to the
underside of the floor decks above the ceiling of floors 3 through 12. The
outermost material is a hard layer of fireproofing which does not contain ACM.
The innermost material (which is completely covered by the hard fireproofing) is
acoustical plaster which does contain ACM. This innermost layer is not in
contact with the ventilation systems and is not able to be contacted through
routine ceiling access, nor is it likely to produce levels of asbestos fibers in
the air.

        Asbestos is a naturally-occurring mineral used in many types of
construction. High concentrations of asbestos fibers have been found to be
associated with asbestosis and lung cancer in humans. Most of the evidence for
this has come from individuals who have been associated with mining of the
mineral or have worked with it in shipyards or other settings where
concentrations of asbestos in the air have been high.

        Based upon the April 1994 survey finding, the building's consultant has
revised the Operations and Maintenance Program in order to accurately reflect
the condition and location of ACM in the building. All contractors, including
those hired directly by tenants who work in any Section of the building will be
required to follow the revised procedures. Employees who are not trained in
handling ACM should not remove, drill or otherwise disturb it. Copies of the
procedures are available in the Building Office, 100 California Street, Suite
770, San Francisco California.

        If you should require any additional information regarding this subject,
please do not hesitate to call.

GENERAL ELECTRIC CAPITAL CORPORATION ("GECC") has made or is about to make a
loan (the "Loan") to the Landlord which will be secured by a mortgage or deed of
trust and security agreement (the "Deed of Trust"), covering the real property
described on EXHIBIT A and the buildings and improvements located thereon
(collectively, the "Real Property"). In connection with the making of the Loan,
GECC has requested that the Tenant complete this Tenant Certificate with the
appropriate information as it pertains to the Tenant's lease and to agree to the
requirements set forth herein.

        The undersigned, Tenant, hereby certifies to and agrees with GECC, as to
the following:

ACKNOWLEDGMENT OF LEASE

1.      The Leased Premises contain approximately 4,051 rentable square feet.
        The term of the Lease is for five (5) years, and shall commence on the
        Commencement Date as determined pursuant to the Lease.

2.      The minimum monthly Base Rent initially payable under the Lease is
        $8,439.58, and is subject to adjustment as provided in the Lease.

3       Concurrently with Tenant's execution of the Lease, Tenant is required to
        deliver to Landlord a security deposit of $9,114.75.


                                     Page 1
<PAGE>   66

4.      No rent or other sum which is payable under the Lease has been paid by
        or on behalf of Tenant more than one (1) month in advance.

5.      The Lease, upon execution by the Landlord, is valid and in full force
        and effect, and, to the best of Tenant's knowledge, neither Landlord nor
        Tenant is in default thereunder.

6.      Any improvements required by the Lease to be made by Landlord have been
        completed to the full satisfaction of Tenant, except as required
        pursuant to Exhibit B attached to the Lease.

7.      The Lease has not been assigned, modified, supplemented or amended in
        any way. Tenant shall not enter into any assignment, modification,
        supplement or amendment to the Lease without the prior written consent
        of GECC. The Lease constitutes the entire agreement between the parties
        and there are no other agreements (including any letter agreements)
        between Landlord and Tenant concerning the Leased Premises. Tenant shall
        not, without obtaining the prior written consent of GECC, (a) prepay any
        of the rents, additional rents or other sums due under the Lease for
        more than one (1) month in advance of the due dates thereof, ~)
        voluntarily surrender the Leased Premises or terminate the Lease without
        cause, or (c) assign the Lease or sublet the Leased Premises other than
        pursuant to the provisions of the Lease.

SUBORDINATION

8.      The Lease (including, without limitation, all rights to insurance
        proceeds and condemnation awards, any rights of first refusal, options
        to purchase, and any other rights granted to Tenant pursuant to the
        Lease) is, and shall at all times continue to be, subject and
        subordinate in each and every respect, to (a) the Deed of Trust and to
        any and all liens, security interests, rights and any other interest
        created thereby and to any and all increases, renewals, modifications,
        extensions, substitutions, replacements and/or consolidations of the
        Deed of Trust and the Loan, and ~) any additional financing of the Real
        Property or portions thereof provided by GECC and the liens and security
        interests under the documents evidencing and securing such additional
        financing, and to any increases therein or supplements thereto.

        NON-DISTURBANCE

9.      So long as the Lease is in full force and effect and Tenant is not in
        default in the payment of rent, additional rent, taxes, utility charges
        or other sums payable by Tenant under the terms of the Lease, or under
        any of the other terms, covenants or conditions of the Lease on Tenant's
        part to be performed beyond the period, if any, specified in the Lease
        within which Tenant may cure such default) (a) Tenant's possession of
        the Leased Premises under the Lease shall not be disturbed or interfered
        with by GECC in the exercise of any of its rights under the Deed of
        Trust, including any foreclosure, and (1)) GECC will not join Tenant as
        a party defendant for the purpose of terminating Tenant's interest and
        estate under the Lease in any proceeding for foreclosure of the Deed of
        Trust.


                               EXHIBIT G - Page 2
<PAGE>   67

        ATTORNMENT

10.     If, at any time GECC (or any person, or such person's successors or
        assigns, who acquire the interest of the Landlord under the Lease
        through foreclosure action of the Deed of Trust, or upon a transfer of
        the Real Property by conveyance in lieu of foreclosure, or otherwise)
        shall succeed to the rights of the Landlord under the Lease as a result
        of a default or event of default under the Mortgage, and if the Tenant
        is not then in default under the Lease beyond the time permitted
        therein, if any, to cure such default), then (a) the Lease shall not
        terminate, (0) upon receipt by Tenant of written notice of such
        succession, Tenant shall attorn to and recognize such person as
        succeeding to the rights of the Landlord under the Lease (herein
        sometimes called "Successor Landlord"), upon the terms and conditions of
        the Lease, and (c) Successor Landlord shall accept such attornment and
        recognize Tenant as the Successor Landlord's tenant under the Lease.
        Upon such attornment and recognition, the Lease shall continue in full
        force and effect as, or as if it were, a direct lease between the
        Successor Landlord and Tenant upon all of the terms, conditions and
        covenants (including any right under the Lease on the part of the Tenant
        to extend the term of the Lease) as are set forth in the Lease and which
        shall be applicable after such attornment and recognition.
        Notwithstanding anything to the contrary set forth herein, GECC or such
        Successor Landlord shall not be (i) liable for any act or omission of
        any previous landlord, including the Landlord, (ii) subject to any
        offset, defense or counterclaim which Tenant might be entitled to assert
        against any previous landlord, including the Landlord, (iii) bound by
        any payment of rent or additional rent made by the Tenant to any
        previous landlord (including the Landlord) for more than one (1) month
        in advance, unless the same was paid to and received by the Successor
        Landlord, (iv) bound by any amendment or modification of the Lease
        hereafter made without the written consent of GECC, or (v) liable for
        any deposit that Tenant may have given to any previous landlord
        (including the Landlord) which has not been transferred to the Successor
        Landlord. Further, notwithstanding anything to the contrary set forth
        herein, the liability of GECC for any obligations under the Lease shall
        be limited to GECC's interest in the Real Property. GECC shall not have
        any liability or responsibility under or pursuant to the terms of the
        Lease after it ceases to own an interest in or to the Real Property.

11.     The provisions of this Tenant Certificate regarding attornment by Tenant
        shall be self-operative and effective without the necessity of execution
        of any new lease or other document on the part of any party hereto or
        the respective heirs, legal representatives, successors or assigns of
        any such party. Tenant agrees, however, to execute and deliver at any
        time and from time to time, upon the request of GECC or of any Successor
        Landlord, any instrument or certificate which, in the reasonable
        judgment of GECC or such Successor Landlord may be necessary or
        appropriate in any such foreclosure proceeding or otherwise to evidence
        such attornment, including, if requested, a new lease of the Leased
        Premises on the same terms and conditions as the Lease.

HAZARDOUS MATERIALS


                               EXHIBIT G - Page 3
<PAGE>   68
12.     Tenant shall neither suffer nor itself manufacture, store, handle,
        transport, dispose of, spill, leak or dump any toxic or hazardous waste,
        waste product or substance (as they may be defined in any federal or
        state statute, rule or regulation pertaining to or governing such
        wastes, waste products or substances) on the Leased Premises or on any
        property in the vicinity of the Leased Premises at any time during the
        term (including any renewal term) of the Lease and during Tenant's
        occupancy of the Leased Premises.

NOTICE

13.     Tenant hereby acknowledges and agrees that: (a) from and after the date
        hereof, in the event of any act or omission of Landlord which would give
        Tenant the right, either immediately or after the lapse of time, to
        terminate the Lease or to claim a partial or total eviction, Tenant will
        not exercise any such right (i) until it has given written notice of
        such act or omission to GECC and (ii) until the expiration of thirty
        (30) days following such giving of notice to GECC in which time period
        GECC shall be entitled to cure any such act or omissions of Landlord;
        (b) Tenant shall send to Landlord all copies of any such default, notice
        or statement under the Lease at the same time such notice is sent to
        Landlord; and (c) if GECC notifies Tenant of a default under the Deed of
        Trust and demands that Tenant pay its rent and all other sums due under
        the Lease to GE CC, Tenant shall honor such demand and pay its rent and
        all of the sums due under the Lease directly to GECC or as otherwise
        required pursuant to such notice.

        All notices and other communications from Tenant to GECC shall be in
        writing and shall be delivered or mailed by registered mail, postage
        paid, return receipt requested, or delivered by an overnight courier,
        addressed to GECC at:

<PAGE>   72
                             EXTENSION OPTION RIDER

        This Extension Option Rider ("Extension Rider") is made and entered into
by and between WHLNF REAL ESTATE LIMITED PARTNERSHIP. a Delaware limited
partnership ("Landlord"), and CRL NETWORKS, a California corporation ("Tenant"),
and is dated as of the date of the Office Lease ("Lease") by and between
Landlord and Tenant to which this Extension Rider is attached. The agreements
set forth in this Extension Rider shall have the same force and effect as if set
forth in the Lease. To the extent the terms of this Extension Rider are
inconsistent with the terms of the Lease, the terms of this Extension Rider
shall control.

        1. Option Right. Landlord hereby grants Tenant one (I) option to extend
the Lease Term for a period of five (5) years (the "Option Term"), which option
shall be exercisable only by written Exercise Notice (as defined below)
delivered by Tenant to Landlord as provided below, provided that, as of the date
of delivery of such Exercise Notice, Tenant is not in default under the Lease
and Tenant has not previously been in default under the Lease more than once.
Upon the proper exercise of such option to extend, and provided that, as of the
end of the initial Lease Term Tenant is not in default under the Lease and
Tenant has not previously been in default under the Lease more than once, the
Lease Term shall be extended for the Option Term. The rights contained in this
Extension Rider shall be personal to the original Tenant executing the Lease and
may only be exercised by the original Tenant (and not any assignee, sublessee or
other transferee of Tenant's interest in the Lease) if the original Tenant
occupies the entire Premises as of the date of the Exercise Notice.

        2. Option Rent. The Annual Base Rent payable by Tenant during the Option
Term (the "Option Rent") shall be equal to the "Fair Market Rental Rate" for the
Premises, which for the purposes hereof shall mean the Annual Base Rent at which
tenants. as of the commencement of the Option Term, are leasing non-sublease
space comparable in size, location and quality to the Premises for a comparable
term, which comparable space is located in the Building and first-class office
buildings comparable to the Building in the Financial District of San Francisco,
California, taking into consideration all concessions and inducements
(including, without limitation, tenant improvement allowances) generally being
granted at such time. All other terms and conditions of the Lease shall apply
throughout the Option Term; however, any obligation of Landlord to construct
Tenant Improvements or provide an allowance (if applicable) shall not apply
during the Option Term and Tenant shall, in no event, have the option to extend
the Lease Term beyond the Option Term described in Section 1 above.

3. Exercise of Option. The option contained in this Extension Rider shall be
exercised by Tenant, if at all, only in the following manner: (i) Tenant shall
deliver written notice to Landlord not more than thirteen (13) months nor less
than twelve (12) months prior to the expiration of the initial Lease Term
stating that Tenant may be interested in exercising its option; (ii) Landlord,
after receipt of Tenant's notice, shall deliver notice (the "Option Rent
Notice") to Tenant not less than ten (10) months prior to the expiration of the
initial Lease Term setting forth the Option Rent; and (iii) if Tenant wishes to
exercise such option, Tenant shall, on or before the date (the "Exercise Date")
which is the earlier of (A) the date occurring nine (9) months prior to


                         EXHIBIT A TO EXHIBIT G - Page 1
<PAGE>   73
the expiration of the initial Lease Term, and (B) the date occurring thirty (30)
days after Tenant's receipt of the Option Rent Notice, exercise the option by
delivering written notice ("Exercise Notice") thereof to Landlord, and upon, and
concurrent with such exercise, Tenant may, at its option, object to Landlord's
determination of the Fair Market Rental Rate contained in the Option Rent
Notice, in which case the parties shall follow the procedure and the Fair Market
Rental Rate shall be determined as set forth in Section 4 below. Tenant's
failure to deliver the Exercise Notice on or before the Exercise Date, shall be
deemed to constitute Tenant's waiver of its extension right hereunder.

        4. Determination of Fair Market Rental Rate. In the event Tenant timely
objects in writing to the Fair Market Rental Rate initially determined by
Landlord, Landlord and Tenant shall attempt to agree upon the Fair Market Rental
Rate, using their best good-faith efforts. If Landlord and Tenant fail to reach
agreement within ten (10) business days following Tenant's objection to the Fair
Market Rental Rate (the "Outside Agreement Date"), then each party shall submit
to the other party a separate written determination of the Fair Market Rental
Rate within ten (10) business days after the Outside Agreement Date, and such
determinations shall be submitted to arbitration in accordance with Sections 4.1
through 4.7 below. Failure of Tenant or Landlord to submit a written
determination of the Fair Market Rental Rate within such ten (10) business day
period shall conclusively be deemed to be the non-determining party's approval
of the Fair Market Rental Rate submitted within such ten (10) business day
period by the other party.

               4.1 Landlord and Tenant shall each appoint one arbitrator who
shall by profession be an independent real estate appraiser who has no financial
interest in Landlord or Tenant and who shall have been active over the five (5)
year period ending on the date of such appointment in the appraisal for rental
purposes of rentals of space in first-class office buildings in the Financial
District of San Francisco, California. The determination of the arbitrators
shall be limited solely to the issue of whether Landlord's or Tenant's submitted
Fair Market Rental Rate is the closest to the actual Fair Market Rental Rate as
determined by the arbitrators, taking into account the requirements of Section 2
of this Extension Rider. Each such arbitrator shall be appointed within thirty
(30) days after the Outside Agreement Date.

               4.2 The two (2) arbitrators so appointed shall within ten (10)
business days of the date of the appointment of the last appointed arbitrator
agree upon and appoint a third arbitrator who shall be qualified under the same
criteria as set forth hereinabove for qualification of the initial two (2)
arbitrators.

               4.3 The three (3) arbitrators shall within twenty (20) days after
the appointment of the third arbitrator reach a decision as to which of the
Landlord's or Tenant's submitted Fair Market Rental Rate is closest to the
actual Fair Market Rental Rate, and the arbitrators shall use whichever
submitted Fair Market Rental Rate is closest to the Fair Market Rental Rate as
the Option Rent to be paid during the Option Term, and shall notify Landlord and
Tenant thereof.


                         EXHIBIT A TO EXHIBIT G - Page 2
<PAGE>   74
               4.4 The decision of the majority of the three (3) arbitrators
shall be binding upon Landlord and Tenant.

               4.5 If either Landlord or Tenant fails to appoint an arbitrator
within thirty (30) days after the Outside Agreement Date, and if such failure
shall continue for an additional fifteen (15) days after written notice thereof
is received by the non-appointing party, the arbitrator appointed by one of them
shall reach a decision, notify Landlord and Tenant thereof, and such
arbitrator's decision shall be binding upon Landlord and Tenant.

               4.6 If the two (2) arbitrators fail to agree upon and appoint a
third arbitrator within the time period provided in Section 1.4.2 above, then
the parties shall mutually select the third arbitrator. If Landlord and Tenant
are unable to agree upon the third arbitrator within ten (10) days, then either
party may, upon at least five (5) days' prior written notice to the other party,
request the Presiding Judge of the San Francisco County Superior Court, acting
in his private and nonjudicial capacity, to appoint the third arbitrator.
Following the appointment of the third arbitrator, the panel of arbitrators
shall within thirty (30) days thereafter reach a decision as to whether
Landlord's or Tenant's submitted Option Rent shall be used and shall notify
Landlord and Tenant thereof.

               4.7 The cost of the arbitrators and the arbitration proceeding
shall be paid by Landlord and Tenant equally, except that each party shall pay
for the cost of its own witnesses and attorneys.

                                    AGREEMENT

        1. PREMISES. Landlord hereby leases the Premises to Tenant and Tenant
hereby hires and takes the Premises from Landlord. The Premises are located at
the address set forth in Section A(l) on page 1 and are more particularly shown
on Exhibit "A" attached hereto and incorporated herein by this reference. The
office building in which the Premises are located is referred to herein as the
"Building."

        2.     TERM.

        2.1 The term of this Lease shall commence on the "Commencement Date"
indicated in Section D on Page 1 and shall extend for the period set forth in
Section C on Page 1. In the event that Landlord, for any reason, cannot tender
possession of the Premises to Tenant on or before the "'Estimated Commencement
Date"' indicated in Section D on Page 1, this Lease shall not be void or
voidable, nor shall Landlord be liable to Tenant in any way as a result of such
failure to tender possession. In the event that Landlord cannot tender
possession of the Premises to Tenant for any reason other than the acts or
omissions of Tenant. Tenant's obligation to pay rent hereunder shall be deferred
by a period of time equal to the delay in Landlord's delivery of possession not
caused by Tenant. If such inability to tender possession of the Premises for
reasons other than the acts or omissions of Tenant continues for a period in
excess of 90 days after the Estimated Commencement Date. Tenant shall have the
right, exercisable by notice to Landlord, to terminate this Lease, but the
suspension of rent obligations and the right of termination pursuant to this
Section 2.1 shall be Tenant's sole remedies in the circumstances herein
described.

        2.2 In the event that Tenant is allowed to enter into possession of the
Premises prior to the Commencement Date, such possession shall be deemed to be
pursuant to, and shall be governed by, the terms, covenants and conditions of
this Lease, including without limitation the covenant to pay rent, as though the
Commencement Date occurred upon the date of taking of possession by Tenant.

        2.3 In the event that the Commencement Date falls on other than the
first day of a month, rent for any initial partial month of the term hereof
shall be appropriately prorated: and if the date of commencement of Tenant's
rent obligations is delayed, pursuant to Section 2.1, the end of the term hereof
shall be correspondingly delayed. At the request of either party hereto, both
parties shall execute a memorandum confirming the date of commencement of
Tenant's rent obligations.

        3. RENT. Beginning on the Commencement Date (subject to adjustment
pursuant to Section 2.1 above), the base rent ("Base Rent") for the Premises
shall be in accordance with the Schedule of Monthly Base Rents set forth in
Section E on Page 2. Each installment of Base Rent shall be payable in advance
on the first day of each and every month throughout the term of this Lease.
Tenant agrees to pay all rent, without offset, demand or deduction of any kind,
to Landlord by mail to the address set forth in Section A(3) on page I or in
such manner, to such other person or at such other place as Landlord may from
time to time designate. Tenant agrees that no payment made to Landlord by check
or other instrument shall contain a restrictive 

                                       4
<PAGE>   8

endorsement of any kind: and if any such instrument should contain a restrictive
endorsement in violation of the foregoing, that endorsement shall have no legal
effect whatever, notwithstanding that such item is processed for payment.

        4.     RENT ESCALATION.

        4.1 Tenant shall pay, as monthly rent hereunder, in addition to the Base
Rent, the sums provided in this Section 4. Tenant shall be advised of any
change, from time to time, in rent escalation payments required hereunder by
written notice from Landlord, which shall include information in such detail as
Landlord may reasonably determine to be necessary in support of such change.
Tenant shall have, 30 days after the receipt of any such notice to protest the
change indicated therein, and Tenant's failure to make such protest in a written
notice to Landlord within such 30-day period shall be conclusively deemed to be
Tenant's agreement to such charges. Notwithstanding any such protest all rent
escalation payments falling due after service of such notice shall be made in
accordance with such notice until the protest has been resolved. whereupon any
necessary adjustment shall be made between Landlord and Tenant. Any audit
arising out of such a protest by Tenant shall be done, at Tenant's expense, in
accordance with generally accepted auditing and management standards by a major
public accounting firm selected by Tenant and approved by Landlord in its
reasonable discretion. Such audit shall be performed at the offices of Paramount
Group, Inc., in New York City or at such other location in the United States as
Landlord may select from time to time for the maintenance of its accounting
records for the Building. Any audit shall be limited to the calendar year
covered by the notice from Landlord as to which Tenant served a timely protest
on Landlord. For example, if in early 1998, Landlord gives Tenant a notice of
sums due for calendar year 1997, and if Tenant protests such charges in a
written notice served on Landlord within 30 days thereafter, then any audit
arising out of such protest shall relate to calendar year 1997.

        4.2 Following the first December 31 during the term of the Lease, Tenant
shall pay Landlord in a single lump sum upon billing therefor, Tenant's
Percentage Share (as defined in Section G on Page 2 of the Lease) of each of the
following amounts: (1) the amount (if any) by which Real Estate Taxes for the
then current tax fiscal year exceed the Real Estate Taxes for the Base Year for
Real Estate Taxes set forth in Section F on Page 2; (2) the amount (if any) by
which Operating Costs for the just completed calendar year exceed the Operating
Costs for the Base Year for Operating Costs set forth in Section F on Page 2;
and (3) the amount (if any) by which Utility Costs for such calendar year exceed
the Utility Costs for the Base Year for Utility Costs set forth in Section F on
Page 2. At the same time Tenant shall also pay to Landlord one-twelfth of
Tenant's Percentage Share of such amounts for each month that has commenced
since December 31, as estimated payments towards Tenant's share of the Real
Estate Taxes, Operating Costs, and Utility Costs for the following year.
Following each succeeding December 31, Landlord again shall determine in the
same fashion the increase or decrease (if any) in annual Real Estate Taxes,
Operating Costs, and Utility Costs over or under those for the previous year,
and if there is an increase Tenant shall pay to Landlord in a single lump sum
upon billing Tenant's Percentage Share of the increase plus one-twelfth of
Tenant's Percentage Share of such increase for each month that has then
commenced in the new calendar year, or if there is a decrease Landlord shall
refund to Tenant or, at Landlord's option, credit against the next rent 

                                       5
<PAGE>   9

falling due under the Lease the amount of the overpayment made by Tenant during
the preceding calendar year, provided that the amount of such refund or credit
shall in no event exceed the total payments made by Tenant during the calendar
year toward Tenant's Percentage Share of excess Real Estate Taxes, Operating
Costs and Utility Costs. Thereafter, with each month's Base Rent until the next
adjustment hereunder, Tenant shall pay one-twelfth of Tenant's Percentage Share
of the cumulative excess (if any) of Real Estate Taxes, Operating Costs and
Utility Costs over the Base Year Real Estate Taxes, Operating Costs and Utility
Costs. The Real Estate Taxes for any partial fiscal year at the end of the Lease
term and the Operating Costs and Utility Costs for any partial calendar year at
the end of the Lease term shall be appropriately prorated.

        For purposes hereof, "Real Estate Taxes" shall include any form of
assessment, license fee, license tax, business license fee, commercial rental
tax, levy, penalty, charge, tax or similar imposition (other than net income,
inheritance or estate taxes), imposed by any authority having the direct or
indirect power to tax, including any city, county, state or federal government,
or any school, agricultural, lighting, drainage, flood control or other special
district thereof, as against any legal or equitable interest of Landlord in the
Premises or in the real property of which the Premises and the Building are a
part, including, but not limited to, the following:

               (i)    Any tax on Landlord's "right" to rent or "right" to
other income from the Premises or as against Landlord's business of leasing the
Premises;

               (ii)   Any assessment, tax, fee, levy or charge in substitution,
partially or totally, of any assessment, tax, fee, levy or charge previously
included within the definition of Real Estate Taxes, it being acknowledged by
Tenant and Landlord that Proposition 13 was adopted by the voters of the State
of California in the June, 1978 Election and that assessments, taxes, fees,
levies and charges may be imposed by governmental agencies for such services as
fire protection, street, sidewalk and road maintenance, refuse removal and for
other governmental services formerly provided without charge to property owners
or occupants. It is the intention of Tenant and Landlord that all such new and
increased assessments, taxes, fees, levies and charges be included within the
definition of "Real Property Taxes" for the purpose of this Lease;

               (iii)  Any assessment, tax, fee, levy or charge allocable to or
measured by the area of the Premises or the rent payable hereunder, including,
without limitation, any gross income tax or excise tax levied by the State, City
or Federal government, or any political subdivision thereof, with respect to the
receipt of such rent, or upon or with respect to the possession, leasing,
operating, management, maintenance, alteration, repair, use or occupancy by
Tenant of the Premises, or any portion thereof:

               (iv)   Any assessment, tax, fee, levy or charge upon this
transaction or any document to which Tenant is a party, creating or transferring
an interest or an estate in the Premises;

               (v)    Any assessment, tax, fee, levy or charge by any
governmental agency related to any transportation plan, fund or system
instituted within the geographic area of which the Building is a part; or

                                       6
<PAGE>   10

               (vi)   Reasonable legal and other professional fees, costs and
disbursement incurred in connection with proceedings to contest, determine or
reduce real property taxes.

The definition of "Real Estate Taxes," including any additional tax the nature
of which was previously included within the definition of "Real Estate Taxes,"
shall include any increases in such taxes, levies, charges or assessments
occasioned by increases in tax rates or increases in assessed valuations,
whether occurring by sale or otherwise.

        As used in this Lease, the term "Operating Costs" shall mean all costs
and expenses of management, operation, maintenance, overhaul, improvement or
repair of the Building, the common areas and the Site, as determined by standard
accounting practices, including the following costs by way of illustration but
not limitation:

               (a)    Any and all assessments imposed with respect to the
Building, common areas, and/or the site on which the Building is located,
pursuant to any covenants, conditions and restrictions affecting the site,
common areas or Building;

               (b)    Any costs, levies or assessments resulting from statutes
or regulations promulgated by any governmental authority in connection with the
use or occupancy of the Building or the Premises;

               (c)    Costs of all insurance obtained by Landlord;

                     (ii)    costs of any structural repairs (except as provided

                     (kk)    cost of Landlord's general corporate overhead and

with the Premises and/or Building, including without limitation costs of
heating, ventilation and air conditioning for the Premises and/or Building,
costs of furnishing gas, electricity and other fuels or power sources to the
Premises and/or Building, and costs of furnishing water and sewer services to

        The term "Building" as used in this Section 4,2 shall be deemed to
include not only the Building but also any parking facility owned, leased or
operated by Landlord in order to meet the parking requirements of the Building.

        If the average occupancy of the rentable area of the Building during the
Tenant's Base Year for Operating and Utility Costs as set forth in Section F on
page 2 or during any other calendar year of the Lease term is less than 90% of
the total rentable area of the Building, the Operating Costs and Utility Costs
shall be adjusted by Landlord for such calendar year, prior to the pass-through
of Operating Costs and Utility Costs to Tenant pursuant to this Section 4.2, to
reflect what they would have been had 90% of the rentable area been occupied
during that year. In making such calculation, the Landlord's reasonable opinion
of what portion, if any, of each cost was affected by changes in occupancy shall
be binding upon the parties.

        5.     TAX ON TENANT'S PROPERTY; OTHER TAXES.

        5.1 Tenant shall be liable for, and shall pay at least 10 days before
delinquency, and Tenant hereby indemnifies and holds Landlord harmless from and
against any liability in connection with, all taxes levied directly or
indirectly against any personal property, fixtures, machinery, equipment,
apparatus, systems and appurtenances placed by Tenant in or about, or utilized
by Tenant in, upon or in connection with, the Premises ("Equipment Taxes"). If
any Equipment Taxes are levied against Landlord or Landlord's property or if the
assessed value of Landlord's property is increased by the inclusion therein of a
value placed upon such personal property, fixtures, machinery, equipment,
apparatus, systems or appurtenances of Tenant, and if Landlord, after written
notice to Tenant, pays the Equipment Taxes or taxes based upon such an increased
assessment (which Landlord shall have the right to do regardless of the validity
of such levy, but only under proper protest if requested by Tenant prior to such
payment and if payment under protest is permissible), Tenant shall pay to
Landlord upon demand, as additional rent hereunder, the taxes so levied against
Landlord or the proportion of such taxes resulting from such increase in the
assessment; provided, however, that in any such event Tenant shall have the
right, in the name of Landlord and with Landlord's full cooperation, but at no
cost to Landlord, to bring suit in any court of competent jurisdiction to
recover the amount of any such tax so paid under protest, and any amount so
recovered shall belong to Tenant.

                                       10
<PAGE>   14

        5.2 If the tenant improvements in the Premises, whether installed and/or
paid for by. Landlord or Tenant and whether or not affixed to the real property
so as to become a part thereof, are assessed for real property tax purposes at a
valuation higher than the valuation at which tenant improvements conforming to
Landlord's building standards in other space in the Building are assessed, then
the real property taxes and assessments levied against Landlord or Landlord's
property by reason of such excess assessed valuation shall be deemed to be
Equipment Taxes and shall be governed by the provisions of Section 5.1. Any such
amounts, and any similar amounts attributable to excess improvements by other
tenants of the Building and recovered by Landlord from such other tenants under
comparable lease provisions, shall not be included in Real Estate Taxes for
purposes of rent escalation under Section 4 of this Lease.

        5.3 Tenant shall pay, as additional rent hereunder, upon demand and in
such manner and at such times as Landlord shall direct from time to time by
written notice to Tenant, any excise, sales, privilege or other tax, assessment
or other charge (other than income or franchise taxes) imposed, assessed or
levied by any governmental or quasi-governmental authority or agency upon
Landlord on account of this Lease, the rent or other payments made by Tenant
hereunder, any other benefit received by Landlord hereunder, Landlord's business
as a lessor hereunder, or otherwise in respect of or as a result of the
agreement or relationship of Landlord and Tenant hereunder.

        6.     SECURITY DEPOSIT AND OTHER SECURITY.

        6.1 A deposit (the "Security Deposit") in the amount set forth in
Section H on page 2 shall be paid by Tenant upon execution of this Lease and
shall be held by Landlord without liability for interest and as security for the
performance by Tenant of Tenant's covenants and obligations under this Lease, it
being expressly understood that the Security Deposit shall not be considered an
advance payment of rent or a measure of Landlord's damages in case of default by
Tenant. Upon the occurrence of any breach or default under this Lease by Tenant,
Landlord may, from time to time, without prejudice to any other remedy, use the
Security Deposit or any portion thereof to the extent necessary to make good any
arrearages of rent or any other damage, injury, expense, or liability caused to
Landlord by such breach or default, Following any application of the Security
Deposit, Tenant shall pay to Landlord on demand an amount to restore the
Security Deposit to its original amount. In the event of bankruptcy or other
debtor relief proceedings by or against Tenant, the Security Deposit shall be
deemed to be applied first to the payment of rent and other charges due
Landlord, in the order that such rent or charges became due and owing, for all
periods prior to filing of such proceedings, Landlord shall not be required to
keep the Security Deposit separate from its general funds. Upon termination of
this Lease any remaining balance of the Security Deposit shall be returned by
Landlord to Tenant within 14 days after termination of Tenant's tenancy.

        6.2 As additional partial security for the faithful performance of its
obligations under this Lease, Tenant hereby grants Landlord a security interest
in all furniture, fixtures, equipment, and all other personal property now owned
or hereafter acquired by Tenant and located on the Premises for use in Tenant's
business operated in the Premises (the "Collateral"), and all accessions to,
and the proceeds, increases, or products of, the whole or any part of the
Collateral. 

                                       11
<PAGE>   15

Tenant represents and warrants to Landlord that such security interest shall at
all times be senior to any other liens or encumbrances against the Collateral,
This Section 6.2 shall constitute a security agreement for such Collateral
between Landlord and Tenant, which shall terminate upon the later of (a) the
expiration or termination of this Lease or (b) the full performance of all
Tenant's obligations under the Lease, Upon execution of this Lease, Tenant
agrees to execute and cooperate in filing a UCC-1 financing statement and/or
fixture filing with the California Secretary of State and/or the Los Angeles
County Recorder, as appropriate, in order to perfect Landlord's security
interest in the Collateral, Such financing statement and/or fixture filing shall
be renewed by the parties from time to time before its expiration, and shall be
supplemented by the parties from time to time, as Landlord may request, by the
preparation and filing with the Secretary of State and/or County Recorder, as
appropriate, of an inventory of all items included within the Collateral at the
time of the inventory.

        Tenant shall initiate and maintain, or defend, at its sole expense, any
proceeding which may affect or protect its title to, or Landlord's interest in,
all, or any part of, the Collateral, Such obligation shall not apply to any
claims on title arising through Landlord or Landlord's successors-in-interest
after Landlord takes title to the Collateral, if ever. Tenant shall take all
steps necessary to protect the Collateral from damage or destruction, and shall
not, without the prior written consent of Landlord, transfer all or any part of
the Collateral, Except in the ordinary course of business, Tenant shall not,
without obtaining the prior written consent of Landlord, sell, lease, encumber
or otherwise dispose of any part of the Collateral, provided however that Tenant
shall have the right to sell any part of the Collateral after having given
Landlord written notice at least five business days prior to such sale on
condition that such Collateral shall be replaced immediately thereafter by
another piece which is either of equal or greater value, and which shall
thereafter become a part of the Collateral.

        Tenant shall maintain the Collateral, and each part thereof, in good
order and repair at Tenant's own cost and expense, and shall not use the
Collateral, or any part thereof, in a manner that would subject the Collateral
to waste or undue deterioration. Tenant assumes all risk of loss to the
Collateral, and Tenant shall not be released from any obligations under this
Lease arising out of any loss, damage or disrepair suffered by the Collateral,
and all parts thereof, Landlord may, upon giving Tenant at least twenty-four
hours written notice, enter the Premises at any reasonable business hour, to
inspect the Collateral.

        Should Tenant be in default under the terms of the Lease, Landlord shall
have, in addition to Landlord's rights as a landlord at law, equity, or under
the terms of the Lease, the rights and remedies of a secured party under the
California Commercial Code, as well as the rights and remedies provided for at
law, in equity or in the Lease. Nothing in this Section 6.2 shall be deemed to
limit in any way Landlord's remedies in the event of Tenant's default, Landlord
shall not be required to exhaust all or any of the Collateral before preceding
with Landlord's other remedies. Landlord may pursue its remedies in any order
that Landlord sees fit. To the extent allowed by law, Tenant waives notice of
foreclosure, notice of sale and advertisement of sale.

        7. LATE PAYMENTS. All covenants and agreements to be performed by Tenant
under any of the terms of this Lease shall be performed by Tenant at Tenant's
sole cost and 

                                       12
<PAGE>   16

expense and without any abatement of rent. Tenant acknowledges that the late
payment by Tenant to Landlord of any sums due under this Lease will cause
Landlord to incur costs not contemplated by this Lease, the exact amount of such
cost being extremely difficult and impractical to fix. Such costs include,
without limitation, processing and accounting charges, and late charges that may
be imposed on Landlord by the terms of any note or other obligation secured by
any encumbrance covering the Premises or the Building of which the Premises are
a part. Therefore, if any monthly installment of rent is not received by
Landlord by the date when due, or if Tenant fails to pay any other sum of money
due hereunder, Tenant shall pay to Landlord, as additional rent, the sum of ten
percent (10%) of the overdue amount as a late charge. Landlord's acceptance of
any late charge, or interest pursuant to Section 33.9, shall not be deemed to be
liquidated damages, nor constitute a waiver of Tenant's default with respect to
the overdue amount, nor prevent Landlord from exercising any of the other rights
and remedies available to Landlord under this Lease or any law now or hereafter
in effect, Further, in the event such late charge is imposed by Landlord for 2
consecutive months for whatever reason, Landlord shall have the option to
require that, beginning with the first payment of rent due following the
imposition of the second consecutive late charge, rent shall no longer be paid
in monthly installments but shall be payable 3 months in advance.

        8. USE OF PREMISES. Tenant, and any permitted subtenant or assignee,
shall use the Premises only for the use described in Section I on page 2. Any
other use of the Premises is absolutely prohibited. Tenant shall not use or
occupy the Premises in violation of any recorded covenants, conditions and
restrictions affecting the land on which the Building is located nor of any law,
ordinance, rule and regulation. Tenant shall not do or permit to be done
anything which will invalidate or increase the cost of any fire, extended
coverage or any other insurance policy covering the Building or property located
therein and shall comply with all rules, orders, regulations and requirements of
any applicable fire rating bureau or other organization performing a similar
function. Tenant shall promptly upon demand reimburse Landlord as additional
rent for any additional premium charged for any insurance policy by reason of
Tenant's failure to comply with the provisions of this Section 8. Tenant shall
not do or permit anything to be done in or about the Premises which will in any
way obstruct or interfere with the rights of other tenants of occupants of the
Building, or injure or annoy them, or use or allow the Premises to be used for
any improper, immoral, unlawful or objectionable purpose, nor shall Tenant
cause, maintain or permit any nuisance in, on or about the Premises. Tenant
shall not commit or suffer to be committed any waste in or upon the Premises and
shall keep the Premises in first class repair and appearance. Tenant shall not
place a load upon the Premises exceeding the average pounds of live load per
square foot of floor area specified for the Building by Landlord's architect,
with any partitions to be considered a part of the live load. Landlord reserves
the right to prescribe the weight and position of all safes, files and heavy
equipment which Tenant desires to place in the Premises so as to distribute
properly the weight thereof. Tenant's business machines and mechanical equipment
which cause vibration or noise that may be transmitted to the Building structure
or to any other space in the Building shall be so installed, maintained and used
by Tenant as to eliminate such vibration or noise. Tenant shall be responsible
for the cost of all structural engineering required to determine structural
load. In any event, unless specifically authorized herein, Tenant shall not
prepare or serve, or authorize the preparation or service of, food or beverages
in the Premises, except only the occasional 

                                       13
<PAGE>   17

preparation of coffee, tea, hot chocolate and other such common refreshments for
Tenants and its employees. Tenant shall not conduct any auction in or about the
Premises or the Building without Landlord's prior written consent.

        9.     BUILDING SERVICES.

        9.1 Throughout the term of this Lease, subject to shortage and accidents
beyond Landlord's reasonable control, and subject to reimbursement pursuant to
Section 4.2, Landlord shall repair and maintain all structural elements of the
Building and common areas (including, without limitation, the structural walls,
doors, floors, ceilings, roof, elevators, stairwells, lobby, heating system, air
conditioning system, telephone cable riser for Building-standard service from
the Building's main terminal to the terminal box on the same floor as the
Premises [but excluding Tenant's telephone equipment and the cable and wiring
from such equipment to the terminal box], plumbing and electrical wiring) and
maintain the exterior of the Premises, including grounds, walks, drives and
loading area, if any, Tenant shall reimburse Landlord upon demand, as additional
rent hereunder, for the cost of any repairs or extraordinary maintenance
necessitated by acts of Tenant or Tenant's employees, contractors, agents,
licensees or invitees. Landlord agrees to operate and maintain the Building
(including Tenant's means of access to the Premises) in a safe, first class,
commercially reasonable manner consistent with the standards of landlords of
other office buildings of comparable size, age and quality in the central
business district of Los Angeles. Such standards shall include standards for
compliance of the Building's structural elements, systems, common areas and
other areas under Landlord's control with all applicable laws, subject to (a)
acts of Tenant or third parties, (b) shortages and accidents beyond Landlord's
reasonable control, (c) commercially reasonable time periods for programs
implementing compliance with laws requiring substantial expenditures, and (d)
reimbursement of Landlord to the extent permitted pursuant to Section 4.2.

        9.2 Provided that Tenant is not in default hereunder, subject to
shortages and accidents beyond Landlord's reasonable control, Landlord shall
furnish building standard heating and air conditioning service Monday through
Friday from 8:00 A.M. to 6:00 P.M., and Saturday from 8:00 A.M. to 1:00 P.M.,
except for holidays. No heating or air conditioning will be furnished by
Landlord on Sundays, holidays or during hours other than as set forth above,
except upon prior arrangement with Tenant and at an extra charge as may be
agreed to between Landlord and Tenant. For purposes of this Section 9.2,
"holidays" shall mean and refer to the holidays of Christmas, New Year's Day,
President's Day, Memorial Day, the Fourth of July, Labor Day, Thanksgiving and
the day after Thanksgiving, as those holidays are defined, recognized or
established by governmental authorities or agencies from time to time and such
other days the New York Stock Exchange is closed. Tenant shall install, at its
expense, such additional air conditioning equipment as may be reasonably
determined by Landlord to be necessary in order to maintain building air
conditioning standards resulting from Tenant's installation and operation of
computer equipment or other special equipment or facilities placing a greater
burden on the air conditioning system than would general office use. Landlord
shall furnish electric current to the Premises in amounts reasonably sufficient
for normal business use, including operation of building standard lighting and
operation of typewriters and standard fractional horsepower office machinery.
Tenant agrees that, at all times during the term of this 

                                       14
<PAGE>   18

Lease, Tenant's use of electric current shall never exceed the capacity of the
feeders to the Building or the risers or wiring installation in the Building.
Tenant shall not install or use or permit the installation or use upon or about
the Premises of any computer or electronic data processing or other equipment
using current in excess of 110 volts or requiring power in excess of 500 watts,
without the express prior written consent of Landlord. Tenant shall pay monthly
upon billing as additional rent under this Lease such sums as Landlord's
building engineer may reasonably determine to be necessary in order to reimburse
Landlord for the additional cost of utilities (including, without limitation,
electricity, gas and other fuels or power sources, and water, and Landlord's
reasonable costs of administration) attributable to the operation of additional
air conditioning equipment and any other requirements in excess of those for
normal office use by reason of the operation of computer equipment or other
special equipment or facilities. At Landlord's election, Landlord may separately
meter at Tenant's expense the electrical usage of some or all of Tenant's
equipment, facilities or Premises. In such event Tenant shall pay the charges
for all such separately metered electrical usage within 10 days after receipt of
a billing therefor. If Landlord meters Tenant's entire Premises, Tenant shall
not be charged for the first 0.66 kilowatt hours per rentable square foot in the
Premises per month (i.e., 982 kilowatt hours per month for Tenant's initial
Premises), which shall be deemed to be building standard electrical usage. Any
amounts billed directly to Tenant shall not be included in the Building's
"Operating Costs" for purposes of Section 4 above. Any extra maintenance
charges or service calls attributable to the actions of Tenant (e.g., continual
adjustments of the thermostats or the failure to keep window coverings closed as
necessary) shall be payable by Tenant to Landlord upon demand, as additional
rent hereunder.

        9.3 Landlord shall furnish unheated water from mains for drinking,
lavatory and toilet purposes drawn through fixtures installed by Landlord, or by
Tenant with Landlord's express prior written consent, and heated water for
lavatory purposes from regular building supply in such quantities as required in
Landlord's judgment for the comfortable and normal use of the Premises. Tenant
shall pay Landlord for additional water which is furnished for any other
purpose. The amount that Tenant shall pay Landlord for such additional water
shall be the average price per gallon charged to the Landlord for the Building
by the entity providing water. increased by 25% to cover Landlord's
administrative expense.

        9.4 Landlord shall furnish janitor service (including washing of windows
with reasonable frequency as determined by Landlord) in and about the Premises,
to the extent necessitated by normal office use of the Premises, Monday through
Friday, holidays excepted. Landlord shall have no obligation to furnish janitor
service for any portion of the Premises which is occupied after 7:00 p.m., is
locked or may be used (to the extent permitted under this Lease) for the
preparation, dispensing or consumption of food or beverages or for any purpose
other than general office use, and Tenant shall keep all such portions of the
Premises in a clean and orderly condition at Tenant's sole cost and expense. In
the event that Tenant shall fail to keep such portions of the Premises in a
clean and orderly condition, Landlord may do so and any costs incurred by
Landlord in connection therewith shall be payable by Tenant to Landlord upon
demand, as additional rent hereunder. Tenant shall also pay to Landlord, as
additional rent hereunder, amounts equal to any increase in cost of janitor
service in and about the Premises if such increase in costs is due to (a) use of
the Premises by Tenant during hours other than normal

                                       15
<PAGE>   19

business hours, or (b) location in or about the Premises of any fixtures,
improvements, materials or finish items (including without limitation wall
coverings and floor coverings) other than those which are of the standard type
adopted by Landlord for the Building. Only those persons who have been approved
by Landlord may perform janitorial services.

        9.5 Landlord shall furnish passenger and freight elevator service in
common with Landlord and other tenants Monday through Friday from 8:00 A.M. to
6:00 P.M. and Saturday from 8:00 A.M. to 1:00 P.M. Landlord shall provide
limited passenger elevator service daily at all times such normal passenger
service is not furnished.

        9.6 Landlord does not warrant that any service will be free from
interruptions caused by repairs, renewals, improvements, changes of service,
alterations, strikes, lockouts, labor controversies, accidents, inability to
obtain fuel, steam, water or supplies or other cause, provided the cause is
beyond the reasonable control of Landlord. Landlord agrees to give Tenant notice
of any extended interruptions of which Landlord has prior knowledge. No
interruption of service shall be deemed an eviction or disturbance of Tenant's
use and possession of the Premises or any part thereof, nor relieve Tenant from
performance of Tenant's obligations under this Lease. Landlord shall not be
liable for any failure to make such repairs or furnish such services unless the
failure shall be reasonably curable by Landlord and nonetheless shall persist
for an unreasonable time after written notice from Tenant of the need for such
repairs or the failure to furnish such service. There shall be no abatement of
rent and no liability of Landlord by reason of any injury to or interference
with Tenant's business arising from the making of any repairs, alterations or
improvements, or provision of any service in or to any portion of the Building,
including the Premises, or in or to the fixtures, appurtenances and equipment
therein: provided that in making such repairs, alterations or improvements or
providing such service Landlord shall interfere as little as reasonably
practicable with the conduct of Tenant's business in the Premises, without,
however, being obligated to incur liability for overtime or other premium
payment to its agents, employees or contractors in connection therewith. If
Tenant's beneficial use of all or a substantial portion of the Premises is
prevented for a period in excess of 3 consecutive business days (excluding
Saturdays, Sundays, and holidays), the Base Rent shall be equitably abated
commencing with the fourth business day and continuing until such use is no
longer prevented. Such abatement, to the extent provided above, shall be
Tenant's sole remedy. Except as provided above, Tenant shall not be entitled to
any abatement or reduction of rent or other remedy by reason of Landlord's
failure to furnish any of the services or Building systems called for by this
Lease when such failure is caused by accident, breakage, repairs, strikes,
lockouts or other labor disturbances or labor disputes of any character, or any
other cause. As a material inducement to Landlord's entry into this Lease,
Tenant waives and releases any rights it may have to make repairs at Landlord's
expense under Sections 1941 and 1942 of the California Civil Code.

        10. CONDITION OF PREMISES. By occupying the Premises, Tenant shall be
deemed to accept the same and acknowledge that they comply fully with Landlord's
covenants and obligations hereunder, subject to completion of any items which it
is Landlord's responsibility hereunder to furnish and which are listed by
Landlord and Tenant upon inspection of the Premises. Tenant acknowledges that
neither Landlord nor any agent, employee or representative of Landlord has made
any representation or warranty with respect to any matter, 

                                       16
<PAGE>   20

including but not limited to any matter regarding the Building or Premises, the
applicable zoning or the effect of other applicable laws, or the suitability or
fitness of the Building or Premises for the conduct of Tenant's business or any
other purpose. Tenant is relying solely on its own investigations with respect
to all such matters. During the term of this Lease, Tenant shall maintain the
Premises in as good condition as when Tenant took possession, ordinary wear and
tear and repairs which are specifically made the responsibility of Landlord
hereunder excepted, and shall repair all damage or injury to the Building or to
fixtures, appurtenances and equipment of the Building caused by Tenant's
installation or removal of its property or resulting from the negligence or
tortious conduct of Tenant, its employees, contractors, agents, licensees and
invitees. In the event of failure by Tenant to perform its covenants of
maintenance and repair hereunder, Landlord may perform such maintenance and
repair, and any amounts expended by Landlord in connection therewith shall be
payable by Tenant to Landlord upon demand, as additional rent hereunder.

        11.    DAMAGE TO PREMISES OR BUILDING.

        11.1 In the event that the Building should be totally destroyed by fire
or other casualty, this Lease shall terminate. In the event the Premises or a
substantial portion of the Building should be so damaged or destroyed that
rebuilding or repairs cannot, in Landlord's opinion, be completed within 180
days after the date of such damage or Landlord will not receive insurance
proceeds sufficient to cover the costs of such repairs, reconstruction and
restoration, Landlord may at its option terminate this Lease upon notice to
Tenant, or Landlord may proceed to restore the Building. In the event that such
rebuilding or repairs can, in Landlord's opinion, be completed within 180 days
after the date of such damage and Landlord will receive insurance proceeds
sufficient to cover the costs of such repairs, reconstruction and restoration,
Landlord shall restore the Building. In the event that Landlord is obligated or
elects to restore the Building, Landlord shall commence to rebuild or repair the
Building reasonably promptly after such damage or destruction and shall proceed
with reasonable diligence to restore it to substantially the condition in which
it was immediately prior to the casualty, except that Landlord shall not be
required to rebuild, repair or replace any part of the partitions, fixtures,
alterations, decorations or other improvements which may have been constructed
by or specifically for Tenant, or by or for other tenants within the Building.
In such event this Lease shall remain in full force and effect, provided that if
Tenant is dispossessed by reason of such casualty from all or a substantial
portion of the Premises for more than 3 consecutive business days, Tenant shall
be entitled to a ratable abatement of the Base Rent during the time and to the
extent the Premises are unfit for occupancy, commencing with the fourth business
day. After Landlord completes Landlord's restoration work on the Premises (i.e.,
any necessary repair work on the Building shell and the Building systems in the
core of the Building), Tenant shall diligently complete Tenant's repairs to its
tenant improvements. If Tenant is unable to conduct its business in all or a
substantial portion of the Premises during Tenant's repairs, then Tenant's
ratable rent abatement shall continue during such repairs, but in no event for
more than 90 days after Landlord completes Landlord's restoration work. The
parties shall cooperate in performing their respective repairs simultaneously
if, in Landlord's reasonable opinion, that is feasible and appropriate. Tenant
shall have the right to terminate this Lease upon notice served upon Landlord
prior to actual completion of Landlord's restoration work on the Premises if
such 

                                       17
<PAGE>   21
restoration work is not substantially completed within 360 days after the
casualty. Rental abatement or lease termination, to the extent provided above,
shall be Tenant's sole remedy. Notwithstanding the foregoing to the contrary, if
the damage is due to the negligence or willful misconduct of Tenant or any of
Tenant's agents, employees or invitees, there shall be no abatement of rent.
Except for abatement of rent as provided hereinabove, Tenant shall not be
entitled to any compensation or damages for loss of, or interference with,
Tenant's business or use or access of all or any part of the Premises resulting
from any such damage, repair, reconstruction or restoration.

        11.2 In the event of any damage or destruction of all or any part of the
Premises, Tenant shall immediately notify Landlord thereof.

        11.3 In the event any holder of a mortgage or deed of trust on the
Building should require that the insurance proceeds payable upon damage or
destruction to the Building by fire or other casualty be used to retire the debt
secured by such mortgage or deed of trust, or in the event any lessor under any
underlying or ground lease should require that such proceeds be paid to such
lessor, Landlord shall in no event have any obligation to rebuild, and at
Landlord's election this Lease shall terminate.

        11.4 With the exception of insurance required to be carried by Tenant
under Section 28 of this Lease, and except as provided in Section 11.2, any
insurance which may be carried by Landlord or Tenant against loss or damage to
the Building or to the Premises shall be for the sole benefit of the party
carrying such insurance and under its sole control. Landlord shall not be
required to carry insurance of any kind on Tenant's property and, except by
reason of the breach by Landlord of any of its obligations hereunder, shall not
be obligated to repair any damage thereto or to replace the same.

        11.5 In addition to its termination rights in Subsection 11.1 above,
Landlord shall have the right to terminate this Lease if any damage to the
Building or Premises occurs during the last 1 2 months of the Term of this Lease
and Landlord estimates that the repair, reconstruction or restoration of such
damage cannot be completed within the earlier of (a) the scheduled expiration
date of the Lease Term, or (b) 60 days after the date of such casualty.

        11.6 Tenant, as a material inducement to Landlord's entering into this
Lease, irrevocably waives and releases its rights under the provisions of
Sections 1932(2) and 1933(4) of the California Civil Code (and any successor
statutes permitting Tenant to terminate this Lease as a result of any damage or
destruction), it being the intention of the parties hereto that the express
terms of this Lease shall control under any circumstances in which those
provisions might otherwise apply.

        12.    EMINENT DOMAIN.

        12.1 In the event that the whole of the Premises, or so much thereof as
to render the balance unusable to Tenant for the purposes leased hereunder, as
reasonably determined by Landlord, shall be lawfully condemned or taken in any
manner for any public or quasi-public use, or conveyed by Landlord in lieu
thereof (a "Taking"), this Lease and the term hereby 

                                       18
<PAGE>   22

granted shall forthwith cease and terminate on the date of the taking of
possession by the condemning authority (the "Date of Taking").

        12.2 In the event of a Taking of a portion of the Premises which does
not result in the termination of this Lease pursuant to Section 12.1, above, the
Base Rent shall be abated in proportion to the part of the Premises so taken.

        12.3 In the event that there is a Taking of a portion of the Building
other than the Premises, and if, in the opinion of Landlord, the Taking is so
substantial as to render the remainder of the Building uneconomic to maintain
despite reasonable reconstruction or remodeling, or if it would be necessary to
alter the Building or Premises materially, Landlord may terminate this Lease by
notifying Tenant of such termination within 60 days following the Date of
taking, and this Lease shall end on the date specified in the notice of
termination, which shall not be less than 60 days after the giving of such
notice.

        12.4 No temporary Taking of the Building or Premises and/or of Tenant's
rights therein or under this Lease shall terminate this Lease or give Tenant any
right to abatement of rent hereunder. Tenant shall be entitled to receive such
portion or portions of any award made for the temporary use with respect to the
period of the taking which is within the term of this Lease, provided that, if
such taking shall remain in force at the expiration or earlier termination of
this Lease, then Tenant shall pay to Landlord a sum equal to the reasonable
costs of performing Tenant's obligations under Section 15 with respect to
Tenant's surrender of the Premises and, upon such payment, shall be excused from
such obligations. For purposes of this Section 12.4, a temporary taking shall be
defined as a taking for a period of 270 days or less.

        12.5 Except for the award in the event of a temporary Taking as
contemplated in Section 12.4, above, Tenant hereby releases and shall have no
interest in, or right to participate with respect to the determination of, any
compensation for any Taking, except only that Tenant shall be entitled to the
portion of any award specifically designated by the condemning authority to be
for any personal property of Tenant included in any such Taking or for any
relocation expenses or business interruption loss incurred by Tenant.

        13.    DEFAULT.

        13.1 The following events shall be deemed to be events of default by
Tenant under this Lease:

               (a)   If Tenant shall fail to pay any installment of rent or any
other sum required to be paid by Tenant under this Lease as due.

               (b)   If Tenant shall fail to comply with any term, provision or
covenant of this Lease, other than provisions pertaining to the payment of
money.

               (c)   If Tenant shall make an assignment for the benefit of
creditors.

                                       19
<PAGE>   23

               (d)    If Tenant shall file a petition under any section or
chapter of the federal Bankruptcy Code, as amended from time to time, or under
any similar law or statute of the United States or any State thereof pertaining
to bankruptcy, insolvency or debtor relief, or Tenant shall have a petition or
other proceedings filed against Tenant under any such law or chapter thereof and
such petition or proceeding shall not be vacated or set aside within 60 days
after such filing.

               (e)    If a receiver or trustee shall be appointed for all or
substantially all of the assets of Tenant and such receivership shall not be
terminated and possession of such assets restored to Tenant within 30 days after
such appointment.

               (f)    If Tenant shall desert or vacate any substantial portion
of the Premises and the same shall remain unoccupied for more than 14 days
thereafter.

               (g)    If Tenant shall assign this Lease or sublet the Premises
in violation of the terms hereof.

        13.2 Any shorter period for cure provided by law notwithstanding, and in
lieu thereof, including without limitation California Code of Civil Procedure
Section 1161, Tenant may cure any monetary default under Subsection 13.1 (a),
above, at any time within 5 days after written notice of default is received by
Tenant from Landlord; and (except as specifically provided otherwise in Section
24) Tenant may cure any non-monetary default within 15 days after written notice
of default is received by Tenant from Landlord, provided that if such
non-monetary default is curable but is of such a nature that the cure cannot be
completed within 15 days, Tenant shall be allowed to cure the default if Tenant
promptly commences the cure upon receipt of the notice and diligently prosecutes
the same to completion, which completion shall occur not later than 60 days from
the date of such notice from Landlord.

        14.    REMEDIES UPON DEFAULT.

        14.1 Upon the occurrence of any event of default by Tenant, Landlord
shall have, in addition to any other remedies available to Landlord at law or in
equity, the option to pursue any one or more of the following remedies (each and
all of which shall be cumulative and non-exclusive) without any notice or demand
whatsoever:

               (a)    Terminate this Lease, in which event Tenant shall
immediately surrender the Premises to Landlord, and if Tenant fails to do so.
Landlord may, without prejudice to any other remedy which it may have for
possession or arrearages in rent, enter upon and take possession of the Premises
and expel or remove Tenant and any other person who may be occupying the
Premises or any part thereof, without being liable for prosecution or any claim
or damages therefor, and Landlord may recover from Tenant the following:

                     (1)     The worth at the time of award of any unpaid rent

hich has been earned at the time of such termination; plus

                                       20
<PAGE>   24

                     (2)     The worth at the time of award of the amount by
which the unpaid rent which would have been earned after termination until the
time of award exceeds the amount of such rental loss that Tenant proves could
have been reasonably avoided; plus

                     (3)     The worth at the time of award of the amount by
which the unpaid rent for the balance of the term after the time of award
exceeds the amount of such rental loss that Tenant proves could have been
reasonably avoided; plus

                     (4)     Any other amount necessary to compensate Landlord
for all the detriment proximately caused by Tenant's failure to perform its
obligations under this Lease or which in the ordinary course of things would be
likely to result therefrom, specifically including but not limited to attorneys'
fees, removal and storage (or disposal) of Tenant's personal property,
unreimbursed leasehold improvement costs (e.g., the amounts Landlord has
expended for leasehold improvements which have not been recovered as of the
termination of the Lease when amortized on a straight-line basis over the
originally scheduled lease term), brokerage commissions and advertising expenses
incurred, expenses of remodeling the Premises or any portion thereof for a new
tenant, whether for the same or a different use, and any special concessions
made to obtain a new tenant; and

                     (5)     At Landlord's election, such other amounts in
addition to or in lieu of the foregoing as may be permitted from time to time by
applicable law.

The term "rent" as used in this Subsection 14.1(a) shall be deemed to be and to
mean all sums of every nature required to be paid by Tenant pursuant to the
terms of this Lease, whether to Landlord or to others. Any such sums which are
based on percentages of income, increased costs or other historical data shall
be reasonable estimates or projections computed by Landlord on the basis of the
amounts thereof accruing during the 24-month period immediately prior to
default, except that if it becomes necessary to compute such sums before a
24-month period has expired, then the computation shall be made on the basis of
the amounts accruing during such shorter period, As used in Subsections 14.1
(a)(1)(1) and (2), above, the "worth at the time of award" shall be computed by
allowing interest from the date the sums became due at the lesser of (i) the
Bank of America prime rate on the due date plus 6%, or (ii) the maximum rate
permitted by law, As used in Subsection 14.1(a)(3), above, the "worth at the
time of award" shall be computed by discounting such amount at the discount rate
of the Federal Reserve Bank of San Francisco at the time of award plus 1%.

               (b)   In the event of any such default by Tenant, in addition to
any other remedies available to Landlord under this Lease, at law or in equity,
Landlord shall also have the right, with or without terminating this Lease, to
re-enter the Premises and remove all persons and property from the Premises;
such property may be removed, stored and/or disposed of pursuant to any
procedures permitted by applicable law, including but not limited to those
described in Section 15.3. No re-entry or taking possession of the Premises by
Landlord pursuant to this Subsection 14.1(b), and no acceptance of surrender of
the Premises or other action on Landlord's part, shall be construed as an
election to terminate this Lease unless a written notice of such 

                                       21
<PAGE>   25

intention be given to Tenant or unless the termination thereof be decreed by a
court of competent jurisdiction.

               (c)   In the event of any such default by Tenant, in addition to
any other remedies available to Landlord under this Lease, at law or in equity,
Landlord shall have the right to continue this Lease in full force and effect,
whether or not Tenant shall have abandoned the Premises. The foregoing remedy
shall also be available to Landlord pursuant to California Civil Code Section
1951.4 and any successor statute in the event Tenant has abandoned the Premises.
In the event Landlord elects to continue this Lease in full force and effect
pursuant to this Subsection 14.1(c), then Landlord shall be entitled to enforce
all of its rights and remedies under this Lease, including the right to recover
rent as it becomes due. Landlord's election not to terminate this Lease pursuant
to this Subsection 14.1(c) or pursuant to any other provision of this Lease, at
law or in equity, shall not preclude Landlord from subsequently electing to
terminate this Lease or pursuing any of its other remedies.

               (d)   Whether or not Landlord elects to terminate this Lease on
account of any default by Tenant, Landlord shall have the right to terminate any
and all subleases, licenses, concessions or other consensual arrangements for
possession entered into by Tenant and affecting the Premises or may, in
Landlord's sole discretion, succeed to Tenant's interest in such subleases,
licenses, concessions or arrangements. If Landlord so elects to succeed to
Tenant's interest, Tenant shall, as of the date of notice by Landlord of such
election, have no further right to or interest in the rent or other
consideration receivable thereunder.

        14.2 Following the occurrence of an event of default by Tenant, Landlord
shall have the 'right to require that any or all subsequent amounts paid by
Tenant to Landlord hereunder, whether in cure of the default in question or
otherwise, be paid in the form of cash, money order, cashier's or certified
check drawn on an institution acceptable to Landlord, or by other means approved
by Landlord, notwithstanding any prior practice of accepting payments in any
different form.

        14.3 All rights, options and remedies of Landlord contained in this
Section 14 and elsewhere in this Lease shall be construed and held to be
cumulative, and no one of them shall be exclusive of the other, and Landlord
shall have the right to pursue any one or more of such remedies or any other
remedy or relief which may be provided by law or in equity, whether or not
stated in this Lease. Nothing in this Section 14 shall be deemed to limit or
otherwise affect Tenant's indemnification of Landlord pursuant to any provision
of this Lease.

        14.4 Landlord shall not be deemed in default in the performance of any
obligation required to be performed by Landlord under this Lease unless Landlord
has failed to perform such obligation within 30 days after the receipt of
written notice from Tenant specifying in detail Landlord's failure to perform;
provided however, that if the nature of Landlord's obligation is such that more
than 30 days are required for its performance, then Landlord shall not be deemed
in default if it commences such performance within such 30-day period and
thereafter diligently pursues the same to completion. Upon any such uncured
default by Landlord. Tenant shall be entitled, as Tenant's sole and exclusive
remedy, to recover from Landlord Tenant's actual 

                                       22
<PAGE>   26

damages (but not lost profits or other incidental or consequential damages)
shown by Tenant to have been directly caused thereby; provided, however (a)
Tenant shall have no right to offset or abate rent in the event of any default
by Landlord under this Lease, except to the extent offset rights are
specifically provided to Tenant in this Lease; (b) Tenant shall in no event be
entitled to terminate this Lease by reason of Landlord's default; and (c)
Tenant's rights and remedies hereunder shall be limited to the extent Tenant has
expressly waived in this Lease any of such rights or remedies, including the
limitation on Landlord's liability contained in Section 33.17 hereof.

        14.5 No waiver by Landlord or Tenant of any violation or breach of any
of the terms, provisions and covenants herein contained shall be deemed or
construed to constitute a waiver of any other or later violation or breach of
the same or any other of the terms, provisions, and covenants herein contained.
Forbearance by Landlord in enforcement of one or more of the remedies herein
provided upon an event of default shall not be deemed or construed to constitute
a waiver of such default. The acceptance of any rent hereunder by Landlord
following the occurrence of any default, whether or not known to Landlord, shall
not be deemed a waiver of any such default, except only a default in the payment
of the rent so accepted, subject to the provisions of Section 33.1.

        15.    SURRENDER OF PREMISES; REMOVAL OF PROPERTY.

        15.1 No act or thing done by Landlord or any agent or employee of
Landlord during the term hereof shall be deemed to constitute an acceptance by
Landlord of a surrender of the Premises unless such intent is specifically
acknowledged in a writing signed by Landlord. The delivery of keys to the
Premises to Landlord or any agent or employee of Landlord shall not constitute a
surrender of the Premises or effect a termination of this Lease, whether or not
the keys are thereafter retained by Landlord, and notwithstanding such delivery
Tenant shall be entitled to the return of such keys at any reasonable time upon
request until this Lease shall have been properly terminated. The voluntary or
other surrender of this Lease by Tenant, whether accepted by Landlord or not, or
a mutual termination hereof, shall not work a merger, and at the option of
Landlord shall operate as an assignment to Landlord of all subleases or
subtenancies affecting the Premises.

        15.2 Upon the expiration of the term of this Lease, or upon any earlier
termination of this Lease, Tenant shall, subject to the provisions of this
Section 15, quit and surrender possession of the Premises to Landlord in as good
order and condition as when Tenant took possession and as thereafter improved by
Landlord and/or Tenant, reasonable wear and tear and repairs which are
specifically made the responsibility of Landlord hereunder excepted. Upon such
expiration or termination, Tenant shall, without expense to Landlord, remove or
cause to be removed from the Premises all debris and rubbish, and such items of
furniture, equipment, free-standing cabinet work, movable partitions and other
articles of personal property owned by Tenant or installed or placed by Tenant
at its expense in the Premises, and such similar articles of any other persons
claiming under Tenant, as Landlord may, in its sole discretion, require to be
removed, and Tenant shall repair at its own expense all damage to the Premises
and Building resulting from such removal.

                                       23
<PAGE>   27

        15.3 Whenever Landlord shall re-enter the Premises as provided in this
Lease, any personal property of Tenant not removed by Tenant upon the expiration
of the term of this Lease, or within 48 hours after a termination by reason of
Tenant's default as provided in this Lease, shall be deemed abandoned by Tenant
and may be disposed of by Landlord without liability to Tenant) in accordance
with Sections 1980 through 1991 of the California Civil Code and Section 1174 of
the California Code of Civil Procedure, or in accordance with any laws or
judicial decisions which may supplement or supplant those provisions from time
to time, or in accordance with any other legally permissible procedure, whether
by public or private sale or otherwise. Landlord shall be entitled to apply any
proceeds of the sale of such items to any sums due to Landlord by Tenant and to
Landlord's costs of removal, storage and sale of such items. Alternatively,
Landlord shall be entitled to treat Tenant's failure to remove such items from
the Premises as either a permitted or unpermitted holdover pursuant to Section
19 of this Lease.

        15.4 All fixtures, alterations, additions, repairs, improvements and/or
appurtenances attached to or built into or on or about the Premises prior to or
during the term hereof, whether by Landlord at its expense or at the expense of
Tenant, or by Tenant at its expense, or by previous occupants of the Premises,
shall be and remain part of the Premises and shall not be removed by Tenant at
the end of the term of this Lease. Such fixtures, alterations, additions,
repairs, improvements and/or appurtenances shall include, without limitation,
floor coverings, drapes, paneling, molding, doors, kitchen and dishwashing
fixtures and equipment, plumbing systems, electrical systems, lighting systems,
silencing equipment, communication systems, all fixtures and outlets for the
systems mentioned above and for all telephone, radio, telegraph and television
purposes, and any special flooring or ceiling installations. Notwithstanding the
foregoing, Landlord may, in its sole discretion, require Tenant, at Tenant's
sole cost and expense, to remove any fixtures, alterations, additions, repairs,
improvements and/or appurtenances attached or built into or on or about the
Premises, and to repair any damage to the Building and Premises occasioned by
the installation, construction, operation and/or removal of such fixtures,
equipment, alterations, additions, repairs, improvements and/or appurtenances.
If Tenant shall fail to complete such removal and repair such damage, Landlord
may do so and may charge the reasonable cost thereof to Tenant.

        15.5 Tenant hereby waives all claims for damages or other liability in
connection with Landlord's re-entering and taking possession of the Premises or
removing, retaining, storing or selling the property of Tenant as herein
provided, and Tenant hereby indemnifies and holds Landlord harmless from any
such damages or other liability, and no such re-entry shall be considered or
construed to be a forcible entry.

        16. COSTS OF SUIT; ATTORNEYS' FEES; WAIVER OF JURY TRIAL.

        16.1. If Tenant or Landlord shall bring any action for any relief,
declaratory or otherwise, against the other arising out of or under this Lease,
including any suit by Landlord for the recovery of rent or possession of the
Premises, the losing party shall pay the successful party its costs of suit,
including, without limitation, a reasonable sum for attorneys' and other
professional fees relating to such suit, and such fees shall be deemed to have
accrued on the 

                                       24
<PAGE>   28

commencement of such action and shall be paid whether or not such action is
contested or prosecuted to judgment.

        16.2 In the event that Landlord shall, without fault of Landlord's part,
be made party to any litigation instituted by Tenant or by any third party
against Tenant, or by or against any person holding under or using the Premises
by license of Tenant, or for the foreclosure of any lien for labor or material
furnished to or for Tenant or of any such other person, Tenant hereby
indemnifies and holds Landlord harmless from and against all costs and expenses,
including reasonable attorneys' fees, incurred by Landlord in or in connection
with such litigation.

        16.3 In order to limit the cost of resolving any disputes between the
parties, and as a material inducement to each party to enter into this Lease,
each party hereby waives the right to a jury trial with respect to any
litigation between the parties arising out of this Lease, Tenant's occupancy of
the Premises, or Landlord's ownership, operation or management of the Building,
irrespective of any rights to a jury trial which either party otherwise then
would have under applicable statutes, constitutions, judicial decisions or other
laws.

        17.    ASSIGNMENT AND SUBLETTING.

        17.1 Except as hereinafter provided, Tenant shall not sublet all or any
part of the Premises, nor assign this Lease, nor enter any license,
"'co-location agreement" or other agreement permitting a third party (other than
Tenant's employees and occasional guests) to use or occupy any portion of the
Premises, without Landlord's express prior written consent, which consent shall
not unreasonably be withheld, conditioned or delayed. (For purposes of the
balance of this Section 17.1 and Sections 17.2 through 17.4, the term
"'sublease" shall be deemed to include licenses, co-location agreements, and
other agreements for use or occupancy of the Premises as described in the
preceding sentence. The terms "subtenant" and "sublet"' shall be construed
accordingly.)

        In order to assist Landlord in evaluating any proposed assignment or
sublease, Tenant agrees to provide Landlord with the proposed subtenant or
assignee's current financial statement and financial statements for the
preceding 2 years and such other information concerning the business background
and financial condition of the proposed subtenant or assignee and of Tenant as
Landlord may reasonably request.

        Landlord and Tenant hereby agree that Landlord's disapproval of any
proposed sublease or assignment hereunder shall be deemed reasonable if based
upon any reasonable factor, including, without limitation, any or all of the
following factors:

               (a)   The rent payable by the proposed transferee would be less
than 85% of the fair market rental value for the space as determined pursuant to
the last paragraph of this Section 17.1 (except as otherwise provided in Section
17.2);

               (b)   The proposed transferee is an existing tenant or occupant
of the Building (except Customers described in Section 17.2 or existing tenants
who lease space on the same floor of the Building as the Premises) or has
negotiated with Landlord within the last twelve 

                                       25
<PAGE>   29

months for space in the Building or is another transferee prohibited by the next
to last paragraph of this Section 17.1;

               (c)   The proposed transferee is a governmental entity;

               (d)   The transaction calls for new demising walls to be built,
and the portion of the Premises proposed to be sublet or assigned is irregular
in shape and/or has inadequate means of ingress and egress;

               (e)   The use of the Premises by the proposed transferee (i) is
not permitted by the use provisions of this Lease, or (ii) might, in Landlord's
reasonable opinion, violate any right for an exclusive use granted by Landlord
to another Tenant in the Building;

               (f)   The transfer would likely result, in Landlord's reasonable
opinion, in a significant increase in the use of the parking areas or common
areas of the Building due to the transferee's employees or visitors, and/or
significant increase in the demand for utilities and services to be provided by
Landlord to the Premises;

               (g)   The assignee or subtenant does not, in Landlord's
reasonable opinion, have the financial capability to fulfill the obligations
imposed by the transfer, or in the case of an assignment, the assignee does not,
in Landlord's reasonable opinion, have income and net worth at least equal to
that of Tenant;

               (h)   The transferee is not, in the Landlord's reasonable
opinion, of reputable or good character or consistent with Landlord's desired
tenant mix;

               (f)   The transferee is a real estate developer or landlord or
is acting directly or indirectly on behalf of a real estate developer or
landlord;

               (j)   The proposed transferee may, in Landlord's reasonable
opinion, increase the chances of significant hazardous waste contamination
within the Premises or the Building; or

               (k)   In the reasonable judgment of the Landlord, the purpose
for which the transferee intends to use the Premises is not in keeping with the
standards of the Landlord for the Building or is in violation of the terms of
any other lease in the Building.

        Notwithstanding the foregoing, Tenant may, subject to the rest of the
terms hereof, sublet all of the Premises or assign this Lease to any entity
controlling, controlled by or under common control with Tenant, (including
assignment or subletting to any corporation resulting from a merger or
consolidation with Tenant, or to any person or entity which acquires all the
assets of Tenant's business as a going concern) provided that, with regard to
each such assignment or subletting: (A) Landlord receives the financial
statements prescribed above and such other financial and background information
as Landlord may request regarding the assignee or subtenant at least 20 days
prior to such proposed assignment or sublease; (B) the Landlord determines, in
its reasonable discretion, that the income and net worth of the assignee or
subtenant comply with the standards prescribed in item (h) above; (C) the use of
the Premises is 

                                       26
<PAGE>   30

not altered; (D) the Landlord determines, in its reasonable discretion, that the
transaction is not being entered into as a subterfuge to avoid the restrictions
on assignment and subletting in the Lease; and (E) the subtenant or assignee
expressly assumes the obligations of Tenant hereunder as prescribed below in
this Section 17.1.

        Neither this Lease nor the term hereby demised shall be mortgaged by
Tenant, nor shall Tenant mortgage, assign, pledge or otherwise transfer the
interest of Tenant in and to any sublease or the rentals payable thereunder or
in the Security Deposit.

        Any sublease, assignment, mortgage, pledge, encumbrance, or transfer
made in violation of this Section 17.1 shall be void and at Landlord's election
shall terminate this Lease.

        Each subtenant, assignee or transferee of Tenant, other than Landlord,
shall assume all obligations of Tenant under this Lease and shall be and remain
liable jointly and severally with Tenant for the payment of the rent, and for
the due performance of all the terms, covenants, conditions and agreements
herein contained on Tenant's part to be performed for the term of this Lease
(provided that in the case of a sublease, the subtenant's obligations shall be
limited to those obligations relating to the subleased space and the common
areas during the sublease term). No sublease or assignment shall be deemed
approved by Landlord unless such subtenant or assignee and Tenant shall deliver
to Landlord a counterpart of such sublease or assignment and an instrument in a
form acceptable to Landlord, which contains a covenant of assumption by the
subtenant or assignee satisfactory in substance and form to Landlord, consistent
with the requirements of this Section 17.1, but the failure or refusal of the
subtenant or assignee to execute such instrument of assumption shall not release
or discharge the subtenant or assignee from its liability as set forth above.

        No subtenant or assignee not complying with the foregoing requirements
shall have any interest in the Security Deposit. Any assignee that does comply
with the foregoing requirements shall automatically succeed to Tenant's position
with respect to the Security Deposit, and Landlord shall have the right to
refund all or any portion of the Security Deposit to the assignee at any time or
under any circumstances with no liability to the assignor.

        Landlord may require that the assignee or subtenant remit directly to
Landlord on a monthly basis, all monies due to Tenant by said assignee or
subtenant. In such event Landlord shall apply the sums received to the
obligations of Tenant and its successors under this Lease.

        In the event of default by any assignee or subtenant or any successor of
Tenant in the performance of any of the terms hereof, Landlord may proceed
directly against Tenant without the necessity of exhausting remedies against
such assignee, subtenant or successor.

        Landlord may consent to subsequent assignments of the Lease or
sublettings or amendments or modifications to the Lease with the assignee or
other successor of Tenant, and without obtaining Tenant's consent thereto, and
any such actions shall not relieve Tenant of liability under this Lease;
provided, however, that Tenant shall not be liable for any additional
obligations undertaken by the assignee or successor in such an amendment or
modification, such as new obligations for additional premises or an extended
term.

                                       27
<PAGE>   31

        Consent by Landlord to one assignment or subletting shall not be deemed
consent to any subsequent assignment or subletting.

        If Tenant is a corporation which, under California law, is not deemed a
publicly-held corporation, or is an unincorporated association or partnership,
the transfer, assignment or hypothecation of any stock or interest controlling
such corporation, association or partnership shall be deemed an assignment
within the meaning and provisions of this Section 17. For purposes hereof,
"control" shall be deemed to refer to any amount, in the aggregate, exceeding
25% of the voting power of such corporation, association or partnership.
Notwithstanding the foregoing, the immediately preceding sentence shall not
apply to any transfer of stock of Tenant if Tenant is a publicly-held
corporation and such stock is transferred publicly over a recognized security
exchange or over-the-counter market.

        Subject to Section 17.2, Tenant agrees that all advertising by Tenant to
market the space in the Premises to be sublet or assigned shall require
Landlord's prior written approval, which shall not be unreasonably withheld,
Subject to Section 17.2, Tenant further agrees that it shall not, without
Landlord's prior written consent, which may be granted or withheld in Landlord's
sole discretion, market any space in the Premises, assign the lease or sublet
any space in the Premises to existing tenants or occupants of the Building, or
to any entity controlling, controlled by, or under common control with any
existing tenant or occupant of the Building, except for any entity controlling,
controlled by or under common control with Tenant, or existing tenants who lease
space on the same floor of the Building as the Premises.

        Subject to Section 17.2, Tenant agrees that it shall not sublet, nor
assign, nor advertise as available for subletting or assignment, nor list with
brokers for subletting or assignment, all or any portion of the Premises for a
consideration which is equal to less than 85% of the fair market rental value,
as determined by Landlord in its reasonable discretion, comparable space in the
Building for a comparable term commencing concurrently with the assignment or
sublease term, with comparable rent credits and tenant improvement allowances.
Within 10 days after Landlord receives any written request from Tenant for
Landlord's estimate of the fair market rental value for specified space (which
request shall identify the space in question, the proposed term and the proposed
rent credits and improvement allowances), Landlord shall notify Tenant in
writing of the fair market rental value for such space for a comparable term
with comparable rent credits and tenant improvement allowances.

        17.2 Landlord acknowledges that Tenant's business to be conducted on the
Premises requires the installation on the Premises of certain communications
equipment by telecommunications customers of Tenant ("'Customers") in order for
such Customers to interconnect with Tenant's terminal facilities.
Notwithstanding anything contained elsewhere in this Section 17, Landlord agrees
not to withhold its consent to any license agreement, sublease or "'co-location
agreement between Tenant and such a Customer for the purposes of permitting such
a telecommunications connection, so long as (a) such Customer agrees in writing
(in a form approved by Landlord in advance in writing) to comply with all
obligations imposed on Tenant under this Lease to the extent relating to the
portion of the Premises in question (including but not limited to insurance,
waiver and indemnity requirements); (b) such licenses, subleases or co-


                                       28
<PAGE>   32

location agreements do not collectively cover more than 50% of the Premises at
any one time; and (c) each such license, sublease or co-location agreement is on
a form for this purpose approved by Landlord in writing in advance. Landlord
agrees that any such form may provide that (i) Tenant's Customer may remove its
equipment from the Premises at any time, subject to the Building's reasonable
rules and insurance requirements, provided that Tenant's Customer repairs any
damage to the Premises or Building caused by such removal; and (ii) title to the
Customer's equipment will remain with such Customer, and such equipment shall
not be deemed part of the Premises. Provided that Tenant's transactions with
Customers comply with items (a), (b) and (c) above, they need not comply with
those requirements of Section 17.1 above regarding financial statements,
advertising, and minimum rental rates. Tenant shall be liable to Landlord for
any violation by its Customers of any provisions of this Lease.

        Landlord agrees to use commercially reasonable, good faith efforts not
to intentionally disclose the identity of Tenant's Customers to other
telecommunications companies, including other tenants in the Building. However,
Landlord can make no guaranties in that regard, and Landlord shall have no
liability to Tenant of any kind for such disclosure, regardless of whether such
disclosure is actually, or alleged to be, negligent or intentional.

        17.3 In the event that Tenant desires to assign this Lease, or to enter
into a sublease, as to all or any portion of the Premises, except (a) where the
subtenant or assignee is en entity controlling, controlled by or under common
control with Tenant, or (b) as permitted under Section 17.2 herein, Tenant
shall, prior to solicitation of offers therefor, give Landlord notice of
Tenant's desire to assign or sublet and of the portion of the Premises to be
affected by the proposed assignment or sublease, Landlord shall have the right,
exercisable by notice to Tenant within 60 days after Landlord's receipt of
Tenant's notice of desire to assign or sublet, to terminate this Lease as to the
portion of the Premises affected by the proposed assignment or sublease, such
termination to be effective as of the date 60 days after notice by Landlord to
Tenant of such termination.

        In the event of a termination of this Lease as to any portion of the
Premises pursuant to this Section 17.3, effective as of such termination, the
Premises shall be deemed to no longer include the portion of the Premises
subject to such termination, Tenant shall surrender possession of that portion
of the Premises in accordance with the provisions of this Lease, and the rent
payable hereunder and Tenant's Percentage Share shall be appropriately adjusted
based upon the rentable area remaining within the Premises.

        If Landlord does not elect to terminate pursuant to this Section 17.3,
and if Tenant does not enter into an assignment or sublease as specified in
Tenant's notice of desire to assign or sublet within 6 months after the
expiration of Landlord's 60-day period for election to terminate, then Tenant
shall again comply with the provisions of this Section 17.3 before assigning
this Lease, or entering into a sublease, as to all or any portion of the
Premises.

        17.4 In the event that Tenant has sought and received Landlord's consent
to assign this Lease, or to enter into a sublease as to all or any portion of
the Premises, the monthly rent payable by Tenant to Landlord, pursuant to
Section 3, shall be increased by 50% of the excess of 

                                       29
<PAGE>   33

(a) the amount to be received by Tenant during each month pursuant to the terms
of the assignment or sublease, over (b) Tenant's monthly rental payable to
Landlord for the space subject to the assignment or sublease. The amounts
referred to in the previous sentence include rent, additional rent, or any other
payment in respect of use or occupancy, or in reimbursement of costs of
leasehold improvements installed by Tenant, and whether paid in a lump sum or
periodic payments; provided however, such amounts shall not include any fees
charged by Tenant to its Customers to the extent such fees are based on Tenant's
services (not square footage of space used by the Customers) as provided under
Section 17.2 herein. In no event shall the total sums payable to the Landlord be
less than the monthly rental Landlord would have received but for such
assignment or sublease.

        The additional rent shall be due and payable to Landlord in accordance
with the schedule specified in the sublease or assignment instrument, and the
failure of any subtenant or assignee to make any payments in accordance with
that schedule shall not affect the obligation of Tenant to pay the additional
rent to Landlord.

        The calculation of the amount of rentable space being sublet shall be
made by Landlord in accordance with the standards of the Building Owners and
Managers Association (provided, however, that if the entire original Premises
are sublet, the rentable area shall be deemed to be as shown in Section B on
page 1). Landlord may require acknowledgment by Tenant of Tenant's concurrence
on the Landlord's calculation of the amount of rentable space being sublet as a
condition to Landlord's consent to any sublease.

        Tenant's obligations for additional rent under this Section 17.4 shall
not commence until Tenant has fully recovered (or would have recovered but for
the subtenant or assignee's default) the following sums out of the portion of
the subtenant or assignee's monthly rent or other payments which exceeds
Tenant's monthly rent for the same space: (a) all expenses incurred and actually
paid by the Tenant for lease commissions in connection with obtaining the
subtenant or assignee; and (b) the amount of the rent paid by Tenant to Landlord
for the space subject to assignment or sublease (not to exceed three months rent
for such space) during the time that Tenant fully vacates (with prior written
notice to Landlord) and does not use such space prior to the subtenant or
assignee occupying such space.

        The provisions of a sublease or assignment instrument consented to by
Landlord cannot be modified, nor the sublease or assignment terminated, other
than in accordance with its terms, without the prior written consent of the
Landlord, which consent shall not be unreasonably withheld. The terms of this
Section 17.4 shall apply to any subleasing or assignment by any subtenant or
assignee.

        17.5 Tenant shall pay to Landlord, promptly upon receipt of a billing
from Landlord, the amount of Landlord's reasonable attorney fees and costs
incurred in connection with Landlord's review or approval of any sublease or
assignment transaction requiring Landlord's consent hereunder, which fees and
costs shall be deemed to be $750 per transaction.

        18. TRANSFER OF LANDLORD'S INTEREST. In the event of any transfer of
Landlord's interest in the Building or Premises, other than a transfer for
security purposes only,

                                       30
<PAGE>   34

the transferor shall be automatically relieved of any and all obligations and
liabilities on the part of Landlord accruing from and after the date of such
transfer, including, without limitation, the obligation of Landlord to return
the Security Deposit as provided in this Lease; provided that the transferor
shall, within a reasonable time, transfer any Security Deposit then held by
Landlord, or any portion thereof remaining after proper deductions therefrom, to
the transferee and shall thereafter notify Tenant of such transfer, of any
claims made against the Security Deposit, and of the transferee's name and
address, by written notice delivered personally (in which case Tenant shall
acknowledge receipt of such notice by signing Landlord's copy of such notice) or
by registered or certified mail.

        19. HOLDING OVER. If Tenant holds over after the term hereof, with or
without the express or implied consent of Landlord, such tenancy shall be from
month-to-month only, and shall not constitute a renewal hereof or an extension
for any further term, and in such case, Base Rent shall be payable at a monthly
rate equal to one hundred fifty percent (150%) of the Base Rent applicable to
the Premises immediately prior to the date of such expiration or earlier
termination. Such month-to-month tenancy shall be subject to every other term,
covenant and agreement contained herein. Nothing contained in this Section 19
shall be construed as consent by Landlord to any holding over by Tenant, and
Landlord expressly reserves the right to require Tenant to surrender possession
of the Premises to Landlord as provided in this Lease upon the expiration or
other termination of this Lease.

        20. NOTICES. In every case when, under the provisions of this Lease, it
shall be necessary or desirable for one party hereto to serve any notice,
request or demand on the other, such notice or demand shall be in writing and
shall be served personally or by deposit in the United States mail, postage and
fees fully prepaid, registered or certified mail, with return receipt requested,
addressed to the applicable address for notice set forth in Section A on page 1.
Landlord or Tenant may, from time to time, by notice in writing served upon the
other as aforesaid, designate a different mailing address or a different person
to whom all such notices or demands are thereafter to be addressed. Service of
any such notice or demand if given personally shall be deemed complete upon
delivery, and if made by mail shall be deemed complete on the day of actual
delivery as shown by the addressee's registry or certification receipt or at the
expiration of 2 business days after the date of mailing, whichever is earlier.

        Notwithstanding the provisions of this Section 20, any notice of default
as described in Section 13.2 and any pleadings or notices given by either party
to the other with respect to any judicial proceeding between the parties shall
be served in the manner prescribed by applicable California law without
reference to this paragraph, and shall be deemed served at such time as is
provided by such applicable law without reference to this paragraph.

        21. QUIET ENJOYMENT. Landlord covenants that Tenant, upon paying the
rent and performing the covenants of this Lease on Tenant's part to be
performed, shall and may peaceably and quietly have, hold and enjoy the Premises
for the term of this Lease.

        22.    TENANT'S FURTHER OBLIGATIONS.

                                       31
<PAGE>   35

        22.1 Except for ordinary wear and as otherwise provided in this Lease,
Tenant shall, at Tenant's expense, keep in good order, condition and repair the
interior of the Premises and shall promptly and adequately repair all damage to
the interior of the Premises and replace or repair all glass, fixtures,
equipment and appurtenances therein damaged or broken, under the supervision and
with the approval of Landlord and, if Tenant does not do so, Landlord may, but
need not, make such repairs and replacements. If Landlord does so, Tenant shall
pay Landlord the cost thereof promptly upon demand, as additional rent
hereunder.

        22.2 Tenant shall comply with all laws, ordinances, rules, regulations,
orders and directives of governmental and quasi-governmental bodies and
authorities having jurisdiction over Tenant or the Premises from time to time
and shall obtain and keep in effect all licenses, permits (including but not
limited to conditional use permits) and other authorizations required with
respect to the business or businesses conducted by Tenant within or from the
Premises or with respect to any special equipment or facilities of Tenant
permitted under the other provisions of this Lease. Tenant and its employees,
agents, licensees and invitees shall also comply with all reasonable rules and
regulations which Landlord may adopt from time to time for the protection and
welfare of the Building and its tenants and occupants; provided that Tenant
shall not be responsible for compliance with any rule or regulation adopted by
Landlord unless or until Tenant is furnished with a copy thereof. The present
rules and regulations for the Building are attached hereto as Exhibit "'B".
Landlord shall have no liability to Tenant for the failure of any other tenant
in the Building to observe the rules and regulations.

        23. ESTOPPEL CERTIFICATE BY TENANT. At any time and from time to time,
within 15 days after written request by Landlord. Tenant shall execute,
acknowledge and deliver to Landlord a statement in writing certifying that this
Lease is unmodified and in full force and effect (or if there have been
modifications, that this Lease is in full force and effect as modified and
stating the modifications), that Tenant knows of no default hereunder by
Landlord and has no right of offset or deduction against the rent or any other
charge payable to Landlord (or specifying any claimed), the amount of any
security posted by Tenant, the dates to which the rent and other charges have
been paid in advance, any increases or decreases of rent that are anticipated,
the commencement date of the Lease and such other matters as may be reasonably
requested by Landlord. It is intended that any statement delivered pursuant to
this Section 23 may be relied upon by any purchaser of the fee or mortgagee or
beneficiary or assignee of any mortgage or trust deed upon the fee of the
Building or Premises. Tenant's failure to deliver the statement within the
period specified above shall be conclusive and binding upon Tenant that the
Lease is in full force and effect without modification except as may be
represented by Landlord, that there are no uncured defaults in Landlord's
performance and that Tenant has no right of offset, counterclaim or deduction
against rental, and that no more than one month's rental has been paid in
advance.

        24. SUBORDINATION AND ATTORNMENT. This Lease is and at all times shall
be subject and subordinate to any ground or underlying leases, mortgages, trust
deeds or like encumbrances, which may now or hereafter affect the Building or
Premises, and to all renewals, modifications, consolidations, replacements and
extensions of any such lease, mortgage, trust deed or like encumbrance. As a
condition precedent to the effectiveness of any such 

                                       32
<PAGE>   36

subordination of this Lease to any future ground or underlying leases or the
lien of any future mortgages, deeds of trust, or like encumbrances, Landlord
shall provide to Tenant a commercially reasonable non-disturbance and attornment
agreement in favor of Tenant executed by such future ground lessor, master
lessor, mortgagee or deed of trust beneficiary, as the case may be, which shall
provide that Tenant's quiet possession of the Premises shall not be disturbed on
account of such subordination to such future lease or lien so long as Tenant is
not in default under any provisions of this Lease. Notwithstanding the
foregoing, Landlord shall have the right to subordinate or cause to be
subordinated any or all ground or underlying leases or the lien of any or all
mortgages, deeds of trust or like encumbrances to the Lease. In the event that
any ground or underlying lease terminates for any reason or any mortgage, deed
of trust or like encumbrance is foreclosed or a conveyance in lieu of
foreclosure is made for any reason, then at the election of Landlord's
successor-in-interest. Tenant shall attorn to and become the tenant of such
successor. Tenant hereby waives its rights under any current or future law which
gives or purports to give Tenant any right to terminate or otherwise adversely
affect this Lease and the obligations of Tenant hereunder in the event of any
such foreclosure proceeding or sale, Tenant covenants and agrees to execute and
deliver to Landlord in the form reasonably required by Landlord, within 10 days
after receipt of written demand by Landlord, any additional documents evidencing
the priority or subordination of this Lease with respect to any ground or
underlying lease or the lien of any mortgage, deed of trust or like encumbrance.
Should Tenant fail to sign and return any such documents within said 10-day
period. Tenant shall be in default hereunder without the benefit of any
additional notice or cure periods, except as may be required by statute.

        25.    RIGHTS RESERVED TO LANDLORD.

        25.1 All portions of the Building are reserved to Landlord, including
exterior building walls, core corridor walls and doors and any core corridor
entrance, but excluding the Premises and the inside surfaces of all walls,
windows and doors bounding the Premises. Landlord also reserves any space in or
adjacent to the Premises used for shafts, stacks, pipes, conduits, fan rooms,
ducts, electric or other utilities, sinks or other building facilities, and the
use thereof, as well as the right to access thereto through the Premises for the
purposes of operation, maintenance, decoration and repair.

        25.2 Landlord shall have the following rights exercisable without notice
(except as specified below) and without liability to Tenant for damage or injury
to property, person or business (all claims for damage being hereby released),
and without effecting an eviction or disturbance of Tenant's use or possession
or giving rise to any claim for setoffs or abatement of rent:

               (a)   .To enter the Premises at all reasonable times during the

service, when no notice shall be required) for the purpose of inspecting the
same, supplying janitorial service, posting notices of non-responsibility,
exhibiting the Premises to prospective tenants, purchasers or others, or making
such repairs or replacements therein as may be required by this Lease or as
Landlord may deem appropriate; provided that Landlord shall use reasonable care
and precaution in order to minimize the 

                                       33
<PAGE>   37

disruptions to Tenant's business. For each of the foregoing purposes, Tenant
shall provide to Landlord a key with which to unlock at any time all of the
doors in, upon and about the Premises, excluding Tenant's vaults and safes.
Landlord may use any other means which Landlord may deem proper to open such
doors in an emergency in order to obtain entry to the Premises, Any entry to the
Premises obtained by Landlord by any means shall not under any circumstances be
construed or deemed to be a forcible or unlawful entry into, or a detainer of,
the Premises, or an eviction of Tenant from the Premises or any portion thereof,
or grounds for any abatement or reduction of rent, Any damages or losses on
account of any such entry by Landlord shall be Tenant's sole responsibility
except as otherwise expressly provided herein, Nothing in this Section 25 shall
be construed as obligating Landlord to perform any repairs, alterations or
decorations, except as otherwise expressly required in this Lease.

               (b)   To change the name or street address of the Premises or
Building.

               (c)   To install and maintain signs on the exterior and interior

after Tenant abandons the Premises.

exterior of the Building or any adjacent or nearby building, land, street or
alley.

               (h)   To grant to anyone the exclusive right to conduct any
business or render any service in the Building, provided such exclusive right
shall not operate to exclude Tenant from the use expressly permitted by this
Lease.

        26. FORCE MAJEURE. Whenever there is provided in this Lease a time
limitation for performance by Landlord or Tenant of any construction, repair,
maintenance or service, the time provided for shall be extended for as long as
and to the extent that delay in compliance with such limitation is due to an act
of God, governmental control or other factors beyond the reasonable control of
Landlord or Tenant, respectively.

        27.    WAIVER OF CLAIMS; INDEMNITY.

        27.1 Tenant, as a material part of the consideration to Landlord, hereby
assumes all risk of, and waives all claims it may have against Landlord, its
agents, employees, affiliates and successors in interest for damage to or loss
of property or personal injury or loss of life resulting from the Building or
Premises or any part thereof becoming out of repair, by reason of any repair or
alteration thereof, or resulting from any accident within the Building or
Premises or on or 

                                       34
<PAGE>   38

about any space adjoining the Building or Premises, or resulting directly or
indirectly from any act or omission of any person, or due to any condition,
design or defect of the Building or Premises, or any space adjoining the
Building or Premises, or the mechanical systems of the Building or Premises,
which may exist or occur, whether such damage, loss or injury results from
conditions arising upon the Premises or upon other portions of the Building, or
from other sources or places, and regardless of whether the cause of such
damage, loss or injury or the means of repairing the same is accessible to
Tenant; provided such assumption and waiver shall not apply to claims caused by
the gross negligence or willful misconduct of Landlord or its agents.

        27.2 Tenant hereby indemnifies and holds Landlord and Landlord's agents,
employees, affiliates and successors in interest harmless from and against any
and all claims, demands, suits, fines, losses and other liabilities for or
relating to injury or loss of life to persons or damage to or loss of property
arising from Tenant's use of the Building or the Premises or from the conduct of
Tenant's business or from any work done, permitted or suffered by Tenant in or
about the Premises or elsewhere, and further indemnifies and holds Landlord and
Landlord's agents, employees, affiliates and successors in interest harmless
from and against any and all claims arising from any breach or default in the
performance of any obligation on Tenant's part to be performed under the terms
of this Lease, or arising from any negligence or intentional conduct of Tenant
or Tenant's agents, employees, contractors, licensees, invitees, representatives
or successors in interest, and from and against all costs, attorneys' and other
professional fees, expenses and liabilities incurred by Landlord or Landlord's
agents, employees, affiliates and successors in interest in or in connection
with any such claim, demand, suit, fine or proceeding. In the event that any
action or proceeding be brought against Landlord or Landlord's agents,
employees, affiliates or successors in interest by reason of any such claim,
Tenant upon notice from Landlord shall defend such action or proceeding at
Tenant's cost and expense by counsel approved by Landlord, such approval not to
be unreasonably withheld.

        28.    INSURANCE.

        28.1 Tenant shall procure and shall maintain in effect, at Tenant's sole
cost and expense throughout the term of this Lease, including any extensions and
renewals thereof, public liability and property damage insurance against claims
for bodily injury, death or property damage occurring upon or about the Premises
or Building, in each case naming Landlord as additional insured and, upon
request by Landlord, naming the holder of any mortgage, deed of trust or like
encumbrance or the lessor under any underlying lease covering the Building as
additional insured, with a limit of liability of not less than $2,000,000.00
single limit. If from time to time, the limits of liability set forth above are,
in the reasonable opinion of Landlord, inadequate, Tenant shall increase such
insurance coverage to an amount as shall be designated by Landlord's notice to
Tenant.

        Tenant shall also procure and maintain, at Tenant's sole cost and
expense throughout the term of this Lease, casualty insurance on Tenant's
personal property in the Premises and any leasehold improvements which the
Tenant installed at its own cost in an amount at least equal to the full
replacement cost of such property, providing coverage against all perils insured
against 

                                       35
<PAGE>   39

by a "fire and extended coverage" policy, as well as sprinkler damage,
vandalism and malicious mischief.

        Tenant shall also obtain the following insurance:

               (a)   Worker's compensation and employer's liability insurance 
in form and amount satisfactory to Landlord.

               (b)   Loss of income and extra expense insurance in such amounts
as will reimburse Tenant for direct or indirect loss of earnings attributable to
all perils commonly insured against by prudent tenants or attributable to
prevention of access to or use of the Premises or the Building as a result of
such perils.

               (c)   Liquor liability insurance coverage in limits of not less
than Five Hundred Thousand Dollars ($500,000) if at any time during the term
hereof any alcoholic beverages of any nature are served on the Premises.

               (d)   Any other form or forms of insurance as Landlord or
Landlord's lender or ground or primary lessors may reasonably require from time
to time in form, in amounts, and for insurance risks against which a prudent
tenant of a comparable size and in a comparable business would protect itself.

        Such policies of insurance shall be with insurance companies acceptable
to Landlord, shall not have a deductible amount exceeding $5,000.00 in the
aggregate, and shall specifically provide that the insurance afforded by such
policies for the benefit of Landlord and Landlord's mortgagees and ground
lessors shall be primary, and that any insurance carried by Landlord or
Landlord's mortgagees and ground lessors shall be excess and non-contributing.
Such policies shall be evidenced by certificates of insurance delivered to
Landlord from time to time showing such insurance to be at all times prepaid and
in full force and effect and providing that such insurance cannot be canceled or
modified upon less than 30 days' prior written notice to Landlord. If at any
time Tenant has not provided Landlord with a then currently effective
certificate of insurance acceptable to Landlord as to any insurance required to
be maintained by Tenant, Landlord may, without further inquiry as to whether
such insurance is actually in force, obtain such a policy and Tenant shall
reimburse Landlord, upon demand as additional rent hereunder, for the cost
thereof, together with Landlord's administrative fee equal to 25% of the
premium.

        28.2 Tenant hereby waives its rights against Landlord and its managing
agent and their respective partners, officers, directors, shareholders,
employees, agents, representatives, contractors, affiliates, successors,
licensees, and invitees with respect to any claims or damages or losses
(including any claims for bodily injury to persons and/or damage to property)
which are caused by or result from (a) risks insured against under any insurance
policy carried by Tenant at the time of such claim, damage, loss or injury, or
(b) risks which would have been covered under any insurance required to be
obtained and maintained by Tenant under this Lease had such insurance been
obtained and maintained as required. The foregoing waivers shall be in addition
to, and not a limitation of, any other waivers or releases contained in this
Lease.

                                       36
<PAGE>   40

        28.3 Tenant shall cause each insurance policy required to be obtained by
it pursuant to this Section 28 to provide that the insurer waives all rights of
recovery by way of subrogation against Landlord and its managing agent and their
respective partners, officers, directors, shareholders, employees, agents,
representatives, contractors, affiliates, successors, licensees, and invitees in
connection with any claims, losses and damages covered by such policy. If Tenant
fails to maintain insurance required hereunder, Tenant shall be deemed to be
self self-insured with a deemed full waiver of subrogation as set forth in the
immediately preceding sentence.

        29.    FIXTURES, TENANT IMPROVEMENTS AND ALTERATIONS.

        29.1 Except as otherwise provided in any rider to this Lease, all
improvements, fixtures and/or equipment which Tenant may install or place in or
about the Premises, and all alterations, repairs or changes to the Premises, and
all signs installed in, on or about the Premises, from time to time, shall be at
the sole cost of Tenant. Landlord shall be without any obligation in connection
therewith. Tenant hereby indemnifies and holds Landlord harmless from any
liability, cost, obligation, expense or claim of lien in any manner relating to
the installation, placement, removal or financing of any such alterations,
repairs, changes, improvements, fixtures, and/or equipment in, and/or about the
Premises.

        29.2 Notwithstanding any provision in this Section 29 to the contrary,
Tenant is absolutely prohibited from making any alterations, additions,
improvements or decorations which: (i) affect any area outside the Premises;
(ii) affect the Building's structure, equipment, services or systems, or the
proper functioning thereof, or Landlord's access thereto; (iii) affect the
outside appearance, character or use of the Building or the common areas: (iv)
weaken or impair the structural strength of the Building; (v) in the opinion of
Landlord, lessen the value of the Building; (vi) will violate or require a
change in any occupancy certificate applicable to the Premises; or (vii) in the
opinion of Landlord, will increase the Building's Operating Costs or Utility
Costs.

        29.3 Before proceeding with any alteration, repair or change which is
not otherwise prohibited in Subsection 29.2 above, Tenant must first obtain
Landlord's written approval of (i) the plans and specifications for all such
work; (ii) with respect to any connecting lines that will be outside the
Premises (if such lines are permitted by Landlord in its sole discretion), a
description of the areas of the Building to which Tenant will require access
both for the initial work and for ongoing maintenance of the improvements or
installations: (iii) the names of all contractors and subcontractors who will
perform such work, all of whom shall be selected from Landlord's then-current
list of approved contractors, which Landlord may compile in Landlord's sole
discretion and will provide to Tenant within ten days following Landlord's
receipt of Tenant's written request; (iv) copies of all liability, casualty and
worker's compensation insurance applicable to the construction, maintenance and
ongoing operation of the improvements and installations: and (v) copies of all
governmental permits required for the work. Landlord's consent to such matters
shall not unreasonably be withheld: provided, however, that with regard to any
such matters which may affect the structural members, the heating, ventilation,
air conditioning or other building systems, exterior walls, windows and doors of
the Building, and 

                                       37
<PAGE>   41

with regard to the installation of any signs outside the Premises, Landlord may
grant or withhold its consent in its unlimited discretion. Landlord may impose,
as a condition of its consent to any alterations, repairs or changes of the
Premises, such requirements as Landlord in its sole discretion may deem
desirable, including, but not limited to, the requirement that Tenant utilize
for such purposes only contractors, materials, mechanics and materialmen
previously used and currently approved by Landlord for work in the Building.

        29.4 After Landlord has approved the change, repair or alteration and
the other items listed in Section 29.3, Tenant shall enter into an agreement for
the performance of such change, repair or alteration with the contractors and
subcontractors approved by Landlord, as provided in Section 29.3. Before
proceeding with any change, repair or alteration Tenant shall (i) provide
Landlord with 10 days' prior written notice thereof: and (ii) pay to Landlord,
within 10 days after written demand, the costs of any increased insurance
premiums incurred by Landlord as a result of such changes, repairs or
alterations. In addition, before proceeding with any change, repair or
alteration, Tenant's contractors shall obtain, on behalf of Tenant and at
Tenant's sole cost and expense: (A) all necessary governmental permits and
approvals for the commencement and completion of such change, repair or
alteration: and (B) a completion and lien indemnity bond, or other surety,
satisfactory to Landlord for such change, repair or alteration. Landlord's
approval of permits pursuant to Section 29.3 shall not relieve Tenant of the
obligation to obtain any other or supplemental permits required by the preceding
sentence.

        29.5 Tenant shall pay to Landlord, as additional rent, the reasonable
costs of Landlord's engineers and other consultants (but not Landlord's on-site
management personnel) for review of all plans, specifications and working
drawings for the change, repair or alteration within 10 business days after
Tenant's receipt of invoices either from Landlord or such consultants. In
addition to such costs, Tenant shall pay to Landlord, within 10 business days
after completion of any change, repair or alteration, the actual, reasonable
costs incurred by Landlord for services rendered by Landlord's management
personnel and engineers to coordinate and/or supervise any of the change, repair
or alteration to the extent such services are provided in excess of or after the
normal on-site hours of such engineers and management personnel.

        29.6 All changes, repairs and alterations shall be performed: (i) in
accordance with the approved plans, specifications and working drawings: (ii)
lien-free and in a first-class and workmanlike manner: (iii) in compliance with
all laws, rules, and regulations of all governmental agencies and authorities:
(iv) in such a manner so as to not to interfere with the occupancy of any other
tenant in the Building, nor impose any additional expense or delay upon Landlord
in the maintenance and operation of the Building: and (v) at such times, in such
manner and subject to rules and regulations as Landlord may from time to time
reasonably designate.

        29.7 Throughout the performance of any such change, repair or alteration
Tenant shall obtain, or cause its contractors to obtain, worker's compensation
insurance and general liability insurance covering the work in compliance with
provisions of Section 28 of this Lease, and builder's risk insurance for the
work reasonably acceptable to Landlord.

                                       38
<PAGE>   42

        29.8 In the event Tenant orders any construction, alteration, decorating
or repair work directly from Landlord, or from the contractor selected by
Landlord, the charges for such work, together with Landlord's administration fee
equal to 15% of the contract price, shall be deemed additional rent under this
Lease, payable upon billing therefor, either in advance of the start of work, or
periodically during construction, or upon the substantial completion of such
work, at Landlord's option.

        30. MECHANIC'S LIENS. Tenant agrees to give Landlord written notice of
the commencement date of any alterations, improvements or repairs to be made in,
to or upon the Premises not later than 15 days prior to the commencement of any
such work, in order to give Landlord time to post notices of nonresponsibility.
Tenant will not permit any mechanic's, materialman's or other lien to be placed
upon the Premises or Building or improvements therein during the term hereof;
and in the event that any mechanic's, materialman's or other lien is filed
against the Premises or Building or improvements therein in connection with any
alteration, repair, improvement or change of, or installation of fixtures or
equipment in, the Premises, Tenant shall cause such lien to be released within
10 days after such filing, either by satisfaction of such claim or by posting of
a bond. Notwithstanding the foregoing, Landlord shall have the right and
privilege at Landlord's option of paying the amount of any such lien or claim,
or any portion thereof, without inquiry as to the validity thereof, and any
amounts so paid, including expenses and interest, shall be deemed additional
rent hereunder due from Tenant to Landlord upon demand.

        31. ALTERNATE SPACE. If the Premises comprise less than a full floor in
the Building, Landlord shall have the privilege of moving Tenant to other space
in the Building reasonably comparable to the Premises. If Tenant is still in the
telecommunications business and maintains telecommunications switching equipment
in the Premises, such space shall be equipped with a switch, ancillary
equipment, and intra-building conduit, complete with associated wiring,
reasonably comparable to Tenant's (and that of Tenant's Customers who maintain
such items in the Premises in accordance with Section 17.2), all at Landlord's
sole cost and expense. Such space shall be completed prior to the relocation of
Tenant, and Landlord shall permit Tenant to operate the equipment in both the
original Premises and the new space for a brief, commercially reasonable period
of time to prevent interruption of service to Tenant's telecommunications
customers, All terms hereof shall apply to the new space with equal force. In
the event of such relocation, Landlord shall give Tenant at least 90 days' prior
notice in writing and shall move Tenant's effects to new space at Landlord's
sole cost and expense at such time and in such manner as to inconvenience Tenant
as little as practicable.

Tenant Parties, provided Landlord's approval of such actions shall first be
obtained, Furthermore, Tenant shall immediately notify Landlord of any inquiry,
test, investigation or enforcement proceeding by or against Tenant or the
Premises concerning the presence of any Hazardous Material.

judgment for possession shall reinstate, continue or extend the term of this

unenforceable clause or provision as may be possible and be legal, valid and
enforceable.

        33.3 The covenants and obligations of Tenant pursuant to this Lease
shall be independent of performance by Landlord of the covenants and obligations
of Landlord pursuant to this Lease, and performance by Tenant of each covenant
and obligation of Tenant pursuant to this Lease shall be a condition precedent

against any such persons or entities or any of their personal assets for
satisfaction of any liability with respect to this Lease. In addition, in

that this Lease is being executed on behalf of Tenant. Each of the partners of
Tenant executing this Lease agrees that he or she and Tenant are irrevocably
bound by execution of any amendment to or modification of this Lease by one or
more of the partners of Tenant. Tenant agrees that each new partner in Tenant
shall be obligated under this Lease, in the same fashion as the existing
partners, and that each new partner shall execute a copy of this Lease and
deliver it to Landlord within 60 days after that partner's admission to the
partnership. In the event that such newly admitted partner is a corporation, the
principal or principals for whose benefit the corporation has been organized
shall execute and deliver to Landlord a lease guaranty in form acceptable to
Landlord. Each newly admitted partner in Tenant shall be jointly and severally
liable with the remaining partners for the performance and satisfaction of all
obligations of the Tenant under this Lease accruing from and after the effective

                              RENT ESCALATION RIDER

        In order to adjust the rent payable under the Lease in accordance with
changes in the cost of living from time to time, Tenant agrees to pay to
Landlord, with the installments of Base Rent, and as additional monthly rent
under the Lease, an amount representing rent escalation. For purposes of
calculating the rent escalation payable hereunder, the Consumer Price Index for
All Urban Consumers, U.S. City Average, All Items (1967 = 100), unadjusted
(herein the "Index") published by the Bureau of Labor Statistics of the United
States Department of Labor for the month of January, 1996 shall be the base
Index figure (the "Base Index"). The Base Index shall be compared to the Index
figure for December of each yen during the term of the Lease, including the
initial partial calendar year if the Lease term commences other then during
December. In the event that the Index figure for December of any year during the
term of the Lease shall be greater than the Base Index, in addition to the Base
Rent Tenant shall pay rent escalation to Landlord in an amount equal to one half
of the same percentage increase in the Base Rent as the percentage increase in
the Index for such December over the Base Index. Such amount shall be payable
monthly commencing with the payment of Base Rent for the month following such
December. By way of example, if the Index for the December in question is 8%
greater than the Base Index, then the Tenant shall pay thereafter as rent
escalation under this rider, until the next annual adjustment, a monthly amount
equal to 4% of the Base Rent, as well as paying the Base Rent itself.

        In the event that the Index for any December during the term of the
Lease is not yet available upon the date that any installment(s) of Base Rent is
due, Tenant shall continue paying the monthly installments of Base Rent and rent
escalation in the amount applicable for such December until the Index for that
month is published, whereupon Tenant shall immediately pay Landlord the rent
escalation which would have been due in the months following such December had
the Index for such December been available. In the event that publication of the
Index is discontinued, Landlord and Tenant agree that the index of consumer
prices which is most closely analogous to the Index shall be used in place of
the Index for calculation of the rent escalation payable hereunder. In the event
that the referents or techniques employed in the calculation of the Index shall
be modified and such modification would have resulted in a different figure for
the Base Index. Landlord and Tenant agree that the Base Index shall be
appropriately adjusted and that the Index, as modified, shall be used as
provided hereunder.

        The term "Base Rent" as used in this Rider shall be deemed to include
the additional monthly rent for conduit space pursuant to Section 2 of the
Telecommunications Conduit Rider (excluding the initial one-time payment of
$9,400 and the cost of installing the interducts from floor P-1 to floor 3) as
well as the Base Rent described in Section E on page 2 and Section 3 on page 3
of the body of this Lease. Thus, the additional rent for the conduit space shall
be adjusted from time to time in the same fashion as the Base Rent.

                        TELECOMMUNICATIONS CONDUIT RIDER

        1.     LEASE AND USE OF CONDUIT. Landlord hereby leases to Tenant, as
part of the Premises for the Lease Term, the conduit space described below (the
"Conduit Space"). Tenant shall use the Conduit Space solely for
telecommunications cable to connect the Premises to the premises of other
telecommunications companies that lease space on the floors of the Building
through which the Conduit Space passes. Any such connection shall require the
mutual written agreement of Tenant and the other affected telecommunications
companies.

        The Conduit Space is contained within two 1-inch interducts running from
floor P-1 through floor 17.

        The interducts from floor 3 through floor 17 run through conduit closets
in the northwest corner of the corridor on each floor. Access to the conduit
closet on each floor shall, at Landlord's election, be restricted so that no
entry to the closet will be permitted unless Landlord's designated contractor or
other representative is present. Landlord may require any installation of cable
in the Conduit Space or any connection of Tenant's cable to the Premises or
cable of other tenants in the Building to be performed by Landlord's approved
contractor. Upon Tenant's written request. Landlord will cause such contractor
to provide Tenant with an advance written breakdown of the costs of the work,
including applicable labor rates. All costs of such installations and
connections (including but not limited to Landlord's administrative fee equal to
10% of the other costs) and the ongoing use and maintenance of such items shall
be at Tenant's sole expense. Tenant shall pay Landlord any costs incurred by
Landlord, together with Landlord's administrative fee, within ten days after
Tenant's receipt of a bill for such items. Tenant's use of the Conduit Space and
such cable and connecting lines shall comply with all applicable laws, the other
provisions of the Lease, and such Building Rules as are adopted by Landlord from
time to time, and shall not interfere in any way with the operation of the
Building or with the use by any other tenant of the Building of such tenant's
premises or the common areas of the Building. All required cabling and
connecting lines shall be installed out of sight.

        Prior to any installation of cable in the Conduit Space or connecting
lines to the Premises or the premises of other tenants. Tenant shall obtain
Landlord's written approval as set forth in Section 29.3 of the Lease, and in
the case of connecting lines to the Premises or cable systems of another tenant,
obtain the written consent of such other tenants to the work.

        2.     CONDUIT RENT. Tenant agrees to pay Landlord additional rent for
the Conduit Space, which initially shall be a one-time payment of $9,400, plus
Landlord's actual costs of installing the interducts from floor P-1 to floor 3,
which have not previously been installed as of the execution of this Lease. The
$9,400 shall be due and payable upon execution of this Lease, and the
installation costs for the interducts from floor P-1 to floor 3 shall be due and
payable within 10 days after billing by Landlord to Tenant. (No portion of such
payments shall be 

                                       1
<PAGE>   64

refundable if the Lease is terminated for any reason.) Thereafter, the
additional rent for the Conduit Space shall be $40 per month, subject to
adjustment as provided below. Such additional rent shall be due and payable to
Landlord on the first day of each month or portion of a calendar month
throughout the balance of the Lease Term, together with Tenant's Base Rent and
other monthly charges, with the first such installment of additional rent due on
the Commencement Date. The amount of such monthly conduit rent shall be adjusted
from time to time in accordance with the Rent Escalation Rider to this Lease to
reflect increases in the Consumer Price Index as described in that Rider.

        3.     INDEMNITY AND WAIVER. Tenant hereby agrees to indemnify and hold
harmless Landlord and its partners, its agent Paramount Group, Inc. and their
respective officers, directors, shareholders, agents and employees
(collectively, the "Landlord Group") from and against any and all claims
(including but not limited to claims for bodily injury or property damage),
actions, mechanic's liens, losses, liabilities, and expenses (including
reasonable attorney fees and costs of defense by Landlord's legal counsel)
(collectively, "Claims"), which may arise from the installation, operation, use,
maintenance or removal of the cable and connecting lines pursuant to this Rider
and the Lease. Similarly, Tenant shall pay upon demand by Landlord the costs to
repair any damage to the Building caused by such installation, operation, use,
maintenance or removal. Tenant hereby waives and releases the Landlord Group
from any Claims Tenant may have at any time (including but not limited to Claims
relating to interruptions in services) arising out of or relating in any way to
the installation, operation, use, maintenance, or removal of the cable and
connecting lines described in this Rider and the Lease, whether or not caused by
the negligence of any member of the Landlord Group or Landlord's contractors.

        4.     REMOVAL OF CABLE AND CONNECTING LINES. Tenant agrees that, upon
the expiration or termination of the Lease, Tenant (or, at Landlord's election,
the contractor designated by Landlord) shall promptly remove, at Tenant's sole
cost and expense, all cable, connecting lines, and other installations installed
under this Rider and the Lease (excepting the conduits themselves, which shall
remain the property of Landlord), and restore those portions of the Building
damaged by such removal to their condition immediately prior to the installation
of such items. If Tenant fails to promptly remove all such items pursuant to
this Section 4, or if Landlord elects to have such work performed by Landlord's
contractor, Landlord may remove such items installed hereunder, and restore
those portions of the Building damaged by such removal to their condition
immediately prior to the installation, in which case Tenant agrees promptly to
pay Landlord's reasonable costs of removal and restoration, including Landlord's
administrative fee.

        5.     APPLICABILITY OF OTHER PROVISIONS. Except as explicitly provided
otherwise herein, Tenant's obligations under the Lease for the protection of the
Building, Landlord, the Landlord Group, and third parties, including but not
limited to Tenant's obligations regarding maintenance, repairs, mechanic's
liens, insurance, attorneys' fees and costs of suit, shall apply in the same
fashion with respect to Tenant's use of the Conduit Space and the cable and
connecting lines described in this Rider as they do with respect to Tenant's use
of the rest of the Premises.

understandings, negotiations, or agreements between the parties, whether written
or oral, with respect to its subject matter.

                             EXTENSION OPTION RIDER

        Provided that Tenant is not in default under this Lease, Tenant shall
have options to extend the term of this Lease for up to two additional two-year
periods following the expiration of the initial term. Tenant shall have the
right to exercise the option for the second two-year period only if Tenant has
previously duly exercised the option for the first two-year period. Tenant may
exercise each such option only by giving Landlord a written notice at least nine
(9) months, but not more than twelve (12) months, prior to the commencement of
the two-year period in question, and only if tenant is not in default at the
time Tenant gives such notice. If Tenant has exercised such option, but is In
default on the date the additional two-year extended term is to commence, then
at Landlord's election, the extended term shall not commence until and unless
the Tenant timely cures such default.

        With respect to each additional two-year term, the Lease shall be
adjusted to reflect the following: (a) a new Base Rent for the Premises equal to
95% of the average Base Rents per rentable square foot charged by Landlord for
telecommunications space in the Building of comparable size and quality in
comparable renewal leases for a comparable term entered into by Landlord within
six months prior to the date Tenant exercises this option (provided, however,
that if no such comparable renewal leases were entered into within such six
month period, then the valuation shall be based on the Base Rent Landlord would
have been willing to accept at that time as reasonably calculated by Landlord in
good faith); and (b) a new rental rate for the Conduit Space based on the
then-prevailing rate being charged by Landlord for similar interducts in the
Building.*

        Landlord shall advise Tenant of such rental adjustments within one month
after Landlord's receipt of Tenant's notice. Tenant shall have ten days
following Tenant's receipt of notice of the rental adjustment within which to
accept such terms by executing any appropriate documentation submitted by
Landlord to Tenant. If Tenant fails to so accept such terms, Tenant's rights to
extend the term pursuant to this Rider shall be cancelled.

        In no event shall the terms offered by Landlord under this Rider bind
Landlord to offer such terms to Tenant or to any other person or entity at any
time except as explicitly set forth in this Rider, nor shall such terms prevent
Landlord from leasing the Premises to any person or entity on different terms if
Tenant does not timely accept the terms determined in accordance with this
Rider.

*BUT IN NO EVENT SHALL THE NEW RENTAL RATE FOR THE CONDUIT SPACE EXCEED $200.

3.      USE

        Lessee will use and occupy the Demised Premises solely for general

that Lessee intends to utilize the Demised Premises for general office use in
connection with the operation of a general business and data communications

<PAGE>   2

will not use the Demised Premises in any manner which will annoy or interfere
with other tenants in the Building and will comply with the Rules and
Regulations listed under Exhibit C. Lessee will not use or occupy the Demised
Premises for any unlawful purpose, and will comply with all present and future
laws, ordinances, regulations, and orders of the United States of America, the
State of Virginia, the Fire Marshall and any other public authority having
jurisdiction over the Demised Premises that may affect the Demised Premises or
Lessee's use and/or occupancy thereof. In no event shall Lessee generate,
manufacture, prepare, use, store, treat or dispose of any polychlorinated
biphenyls ("PCB's"), petroleum products or asbestos, or any hazardous,
radioactive, carcinogenic, or toxic chemicals, substances pollutants,
contaminants, materials or waste, including storage tanks and/or containers
thereof, as such terms are defined under applicable Federal, state and local
laws, ordinances or regulations, in or on the Demised Premises or the Building
on the Property upon which the Demised Premises is located or any portion
thereof, nor shall Lessee use, or suffer the Demised Premises to be used, for
industrial or manufacturing purposes. In the event of any breach of this Section
3, Lessee agrees to defend, indemnify and hold Lessor harmless from and against
any and all claims, damages, expense and liability incurred as a result,
including, but not limited to, costs and attorneys' fees incurred by or on
behalf of Lessor to (I) cure Lessee's breach of this Section 3, (ii) remediate
the effects of Lessee's breach, or (iii) to bring Lessee into compliance with
any and all federal, state and municipal orders, ordinances, laws, and
regulations. The foregoing indemnity shall be deemed to survive the expiration
of this Lease.

4.      RENTAL

        The monthly Rent to be paid for the Demised Premises during the Lease
Term, which Lessee hereby agrees to pay to Lessor in advance, and Lessor hereby
agrees to accept, shall be the sum of Two Thousand One Hundred Sixty-Seven and
seventy-five/one hundredths Dollars ($2,167.75), payable on the first (1st) day
of each calendar month during the Lease Term commencing with the Commencement
Date. Monthly rent payable under this Section 4 shall be hereinafter referred to
as "Monthly Base Rent." Such Monthly Base Rent shall be subject to escalation as
hereinafter provided. If the obligation of the Lessee to pay Rent hereunder
begins on a day other than on the first day of a month, Rent from such date
until the first day of the following month shall be prorated at the rate of
one-thirtieth (1/30) of the Monthly Base Rent for each day payable in advance.
The Lessee will pay Rent without demand, by check to the Lessor or to such other
party or to such other address as Lessor may designate from time to time by
written notice to Lessee, without demand and without deduction, set-off or
counterclaim. If Lessor shall at any time or times accept said Rent after it
shall become due and payable, such acceptance shall not excuse delay upon
subsequent occasions, or constitute, or be construed as, a waiver of any or all
of the Lessor's rights hereunder. The term "Rent" as used herein shall mean each
installment of Monthly Base Rent payable hereunder, all additional Rent plus all
other sums payable by Lessee to Lessor hereunder (including, but not limited to,
late charges and interest).

5.      BASE MONTHLY RENTAL RATE ESCALATION, BASED UPON INCREASES IN REAL ESTATE
        TAXES, OPERATING COST AND ANNUAL ESCALATION.

        A.     DEFINITIONS

               1. Real Estate Taxes shall mean the aggregate amount of real
estate taxes and assessments, general and special, ordinary and extraordinary,
foreseeable or unforeseen, including assessments for public improvements and
betterments, real estate taxes upon any "air rights", front foot benefit
assessments, vault rents, sewer assessments, and special area taxes assessed,
levied or imposed with respect to the Land and the improvements located on the
Land in the manner in which such taxes and assessments are imposed, as of the
Commencement Date provided, that if because of any change in the taxation of
real estate or other tax assessment (including, without limitation, any
occupancy, gross receipts or rental tax) is imposed upon Lessor or the owner of
the Land and/or Building, or upon or with respect to the Land and/or Building,
or the occupancy, rents or income therefrom, in substitution for, or in addition
to, any of the foregoing Taxes, such other tax or assessment shall be deemed
part of the Taxes. Real Estate Taxes shall not include any sales tax or excise
tax imposed by any governmental authority upon the Rent payable by Lessee
hereunder, and in the event that any sales tax or excise tax is 

                                       2
<PAGE>   3

imposed by any governmental authority on the Rent payable by Lessee hereunder,
such sales tax or excise tax shall be paid by Lessee.

               2. Monthly Base Rent shall mean the rate of Monthly Base Rent
originally fixed in Section 4 of this Lease on the date of execution thereof, as
such rate may be subsequently modified or supplemental in any way other than
under the provisions of Sections 5B and 5C hereof.

               3. Lease Term shall be deemed to mean the period beginning with
the Commencement Date in accordance with Exhibit D and ending with the date of
the expiration in accordance with Exhibit D or sooner termination of this Lease
subject to the terms of this Lease.

               4. Operating Costs of the Building shall mean the costs of all

and all other costs and expenses of operating the office area, common area and
garage associated with the Building; provided, however, that Operating Costs of
the Building shall not include (i) leasing commissions and (ii) payments of
principal and interest on any mortgages, deeds of trust or other encumbrances
upon the Building. Operating Costs of the Building shall include, in addition to
the above, the cost of any capital improvements designed to decrease operating
expenses, and any improvements required by law after the initial occupancy. The
cost of such capital improvements shall be amortized over the life of the
particular asset and to this extent, shall be included in Operating Costs of the
Building.

               5. Base Year shall be the period January 1, 1996 to December 31,
1996.

               6. Comparison Year shall mean any twelve month period after the
Base Year which begins with the same first month as the Base Year.

               7. Real Estate Tax Fiscal Year shall mean the period January 1 to
December 31 (or such other period as hereafter may be duly adopted by the State
of Virginia and/or Fairfax County, Virginia, as the fiscal year for real estate
tax purposes; and wherever reference is hereinafter made to January 1, it shall
mean, in the case of such other fiscal year, the first day thereof)

               8. Base Tax Year shall mean the Real Estate Tax Fiscal Year
within which Lessee occupies the Demised Premises or its obligation to pay Rent
occurs, whichever comes earlier.

               9. Base Real Estate Taxes shall mean the taxes payable for the
Base Tax Year.

               10. Lessee's Proportionate Percentage shall mean eighty-eight/one
hundredths percent (0.88%) and shall represent the agreed percentage of the
Building for purposes of computing Lessee's allocable share of any change in
Real Estate Taxes or Operating Costs provided hereunder.

        B.     INCREASES IN REAL ESTATE TAXES

        During the Lease Term, Lessee shall pay to Lessor, as additional Rent,
Lessee's Proportionate Percentage of any increase during the Lease Term in Real
Estate Taxes levied on the Building and the Land on which the Building is
situated over the Base Real Estate Taxes. Lessor shall submit to Lessee a
Statement of such tax increase and Lessee shall pay to Lessor its aforesaid
percentage share of such tax increase for the Real Estate Tax Fiscal Year of
Fairfax 

                                       3
<PAGE>   4

County, Virginia (currently January 1 to December 31) for which such tax
increase is effective and shall, commencing with the first monthly installment
of Rent which is due during such Real Estate Tax Fiscal Year, pay to Lessor as
additional monthly Rent, together with such monthly installment of Rent an
amount equal to one-twelfth (1/12) of Lessee' 5 aforesaid percentage share of
such annual increase in Real Estate Taxes to be applied to Lessee's obligation
thereafter accruing under this Section. If the expiration date of this Lease
does not coincide with the last day of the Real Estate Tax Fiscal Year, the
portion of the increase in Real Estate Taxes payable by Lessee hereunder for the
Real Estate Tax Fiscal Year in which the expiration date occurs, shall be
appropriately adjusted and pro-rated between the Lessor and Lessee, based upon
the respective number of days in such Real Estate Fiscal Year prior to and after
the expiration date.

        C.     INCREASE IN OPERATING COSTS

               (i) For each Comparison Year after the Base Year, as herein
defined, Lessee shall pay to Lessor as additional Rent Lessee's Proportionate
Percentage of the increase (if any) in the Operating Costs of the Building as
herein defined, for such Comparison Year over the Operating Costs of the
Building for the Base Year as herein defined; provided that, Lessee's obligation
to pay Lessee's Proportionate Percentage of any increase in Operating Costs
shall not commence to accrue until the first (1st) anniversary of the
Commencement Date. Within ninety (90) days after the expiration of each
Comparison Year during the Lease Term, or as soon thereafter as is reasonably
possible, a certified public accountant selected by Lessor shall audit the books
and records of Lessor and shall make a determination of the increase in the
Operating Costs of the Building for such Comparison Year over the Operating
Costs of the Building for the Base Year. Lessor shall submit to Lessee a
statement (the "Expense Statement") of the aforesaid determination, including
Lessee's Proportionate Percentage of such increase ("Lessee's Expense Increase
Share"). Within thirty (30) days after the delivery of the Expense Statement,
Lessee shall pay to Lessor Lessee's Expense Increase Share. In the event Lessee
fails to dispute any such Expense Statement within forty-five (45) days
following delivery of such Expense Statement, such Expense Statement shall be
deemed final and conclusive against Lessee.

               (ii) In order to provide for payment by Lessee of Lessee's
Anticipated Expense Increase Share for each Comparison Year on an estimated
monthly installment basis during each Comparison Year, said installments due
with the Monthly Base Rent, Lessee agrees that, commencing with the first
anniversary of the Commencement Date of the Lease, Lessee shall pay to Lessor an
amount equal to one-twelfth (1/12) of Lessee's Anticipated Expense Increase
Share, which amount shall be 3% of the previous year's Monthly Base Rent, plus
Lessee's Proportionate Percentage of any actual increase, if any, in the
Operating Costs of the Building for the prior Comparison Year over the Operating
Costs of the Building for the Base Year, which additional monthly payment shall
be applied as a credit against Lessee's Expense Increase Share for such
Comparison Year. In the event that after the operating expenses for such
Comparison Year have been determined and such additional monthly payments for
Lessee's Anticipated Expense Increase Share are in excess of Lessee's Expense
Increase Share for such Comparison Year, Lessor shall promptly refund such
excess to Lessee. In the event that the amount of such monthly payment is
insufficient to pay the full amount of Lessee's Expense Increase Share for such
Comparison Year, Lessee shall pay to Lessor, within thirty (30) days after the
delivery of the Expense Statement, the entire amount of such deficiency. If this
Lease expires on other than the last day of the Comparison Year, Lessee's
Expense Increase Share shall be equitably adjusted to exclude the portion of
such Comparison Year during which this Lease is not in effect.

               (iii) In the event that the Building is less than ninety-five
percent (95%) occupied for a period exceeding ninety (90) days during the Base
Year or any Comparison Year of this Lease, then those components of Operating
Costs during the Comparison Year which vary according to the level of occupancy
of the Building (e.g., as the case may be, electricity, gas, trash, etc.) will
be adjusted as reasonably estimated by Lessor to reflect the Building as
ninety-five percent (95%) occupied for purposes of determining Lessee's Expense
Increase Share and Lessee's Anticipated Expense Increase Share. It is
recognized, however, that the level of said variable expenses does not
necessarily vary on a linear basis relative to the occupancy level. Expenses
which do not normally vary according to the level of occupancy of the Building,
such as Building Engineer expenses, shall not be adjusted.

                                       4
<PAGE>   5

        D.     BASE RENTAL ADJUSTMENT

        Commencing with the first (1st) anniversary of the Commencement Date and
on each anniversary thereof throughout the term, Lessee's Monthly Base Rent
shall be increased by three percent (3%) of the Monthly Base Rent in effect
immediately preceding such adjustment. Lessee shall pay such increased Rent in
monthly installments commencing with the Monthly Base Rent payment then due.

        E.     PERSONAL PROPERTY TAXES

        Lessee shall pay before delinquency all taxes, assessments, license
fees, and other charges that are levied and assessed against Lessee's personal
property installed or located in or on the Demised Premises, and that become
payable during the term. On demand by Lessor, Lessee shall furnish Lessor with
satisfactory evidence of these payments.

        If any taxes on Lessee's personal property are levied against Lessor or
Lessor's property, or if the assessed value of the Building and other
improvements in which the Demised Premises are located is increased by the
inclusion of a value placed on Lessee's personal property, and if Lessor pays
the taxes on any of these items or the taxes based on the increased assessment
of these items, Lessee, on demand, shall immediately reimburse Lessor for the
sum of the taxes levied against Lessor, or the proportion of the taxes resulting
from the increase in Lessor's assessment. Lessor shall have the right to pay
these taxes regardless of the validity of the levy.

        In the event that any sales tax or excise tax is imposed by any
governmental authority on either the Rent payable by Lessee hereunder or on the
services provided under the Lease hereunder, such sales tax or excise tax shall
be paid by Lessee.

6.      DEPOSIT

        Simultaneously with the execution of this Lease, Lessee shall deposit
with Lessor the sum of Four Thousand Three Hundred Thirty-Five and fifty/one
hundredths Dollars ($4,335.50), as a security deposit for the performance by
Lessee of the provisions of this Lease. Such deposit shall be considered as
security for the payment and performance by Lessee of all Lessee's obligations,
covenants, conditions and agreements under this Lease. In the event of any
default by Lessee hereunder, Lessor shall have the right, but shall not be
obligated, to apply all or any portion of the deposit to cure such default, in
which event Lessee shall be obligated to promptly deposit with Lessor the amount
necessary to restore the deposit to its original amount provided, however, such
defaults and Lessee's liability under this Lease shall thereby be discharged
only pro tanto and Lessee shall remain liable for any amounts that said Security
Deposit shall be insufficient to pay. Lessor shall return the security deposit
to Lessee within thirty (30) days after (i) the Lease has expired, (ii) the
Lessee has surrendered possession of the Demised Premises in accordance with the
terms hereof, and (iii) the Lessee has performed all obligations imposed on the
Lessee hereunder. Lessor shall not be required to pay Lessee interest en the
security deposit. Notwithstanding the foregoing, in the event of the sale or
transfer of Lessor's interest in the Demised Premises or this Lease, Lessor
shall have the right to transfer the Security Deposit to the purchaser or
transferee, in which event Lessee shall look only to the new landlord for the
return of the Security Deposit and Lessor shall thereupon be released from all
liability to Lessee for the return of such Security Deposit.

7.      ASSIGNMENT AND SUBLETTING

               (a) Lessee shall not mortgage or encumber this Lease. Lessee
shall not assign or transfer this Lease, or grant any license or concession
hereunder, or sublet or permit the occupancy or use of the Demised Premises, or
any part thereof (each of the foregoing herein referred to as a "Transfer", and
any person or entity to whom a Transfer is made or proposed to be made being
herein referred to as a "Transferee"), by any person or entity other than Lessee
and its employees, or cause, permit or suffer any Transfer to occur by operation
of law or otherwise, without obtaining the prior written consent of Lessor. In
no event shall Lessee grant any partial assignment of Lessee's interest in this
Lease. Lessee shall deliver not less than thirty (30) days prior written notice
of any proposed Transfer, said notice to further specify the identity of the
proposed Transferee, the terms of the proposed Transfer and such other
information as 

                                       5
<PAGE>   6

Lessor may reasonably request. Lessee agrees to reimburse Lessor for such
reasonable costs as may be incurred by Lessor in the review of the proposed
Transferee's credentials, financial information and other information required
by Lessor.

               (b) Subject to the other provisions of this Section 7, and
provided that (I) Lessee is not and has not been in default hereunder and (ii)
Lessee will remain in possession of in excess of fifty percent (50%) of the
Demised Premises, Lessor agrees that it will not unreasonably withhold or delay
its consent to a proposed Transfer; provided that, notwithstanding the
foregoing, it shall be deemed reasonable for Lessor to withhold its consent to a
proposed Transfer if Lessor determines that: (A) the proposed Transferee or its
business is not of a type and quality suitable for a first-class office
building, (B) the proposed Transferee is a governmental or quasi-governmental
authority, a foreign government or international agency or other organization
entitled to sovereign or other immunity, (C) the proposed assignment or
sub-tenancy or the proposed assignee or subtenant would adversely affect the
other tenants of the Building or would impose an additional, material burden
upon Lessor in its operation of the Building, (D) the proposed Transfer would
impair the reputation of the Building as a first-class office building, (E) the
proposed Transferee has not been demonstrated to Lessor's satisfaction to have
sufficient financial capability and stability to perform its obligations under
this Lease and under such proposed assignment or sublease (as the case may be),
(F) the proposed Transfer would result in more than one (1) sublease being in
effect, (G) the Lease has previously been Transferred, (H) the proposed
Transferee is proposing to engage in a use which (I) is not permitted pursuant
to Section 3 hereof, (ii) is not permitted pursuant to applicable law to be
conducted by the proposed Transferee or within the Demised Premises (or such
lesser portion as is being sublet) or both, (iii) will violate any covenant,
condition, restriction or other matter of record affecting title to the
Building, or any other agreement, judgment or law by which Lessor or the
Building is bound, or (iv) will violate any "exclusive use" or other restrictive
covenant of any other lease of any portion of the Building, (I) the proposed
Transferee is proposing to manufacture, use, store or dispose of Hazardous
Materials in, on or upon the Demised Premises (or such lesser portion as is
being sublet), (J) the rent to be paid in connection with such Transfer is less
than the comparable rents then being charged for similar space in the Building,
or (K) Lessor's lender shall refuse to grant its consent to such Transfer (if
required). Notwithstanding anything herein contained, Lessee shall have no right
to make any Transfer to any person or entity with whom Lessor is negotiating to
lease space in the Building, or to any existing tenant or other occupant of the
Building.

               (c) The consent by Lessor to any Transfer shall not be construed
as a waiver or release of Lessee from the terms of any covenant or obligation
under this Lease, nor shall the collection or acceptance of Rent from any
Transferee constitute a waiver or release of Lessee of any covenant or
obligation contained in this Lease, nor shall any such Transfer be construed to
relieve Lessee from giving Lessor said thirty (30) days notice or from obtaining
the consent in writing of Lessor to any further Transfer. Lessee hereby assigns
to Lessor the rent due from any Transferee and hereby authorizes each such
Transferee to pay said rent directly to Lessor; provided that, so long as Lessee
is not in default hereunder, Lessee shall be authorized to collect the rent from
each such Transferee. Any costs and expenses, including, but not limited to,
reasonable attorney's fees (which shall include the cost of any time expended by
Lessor' 5 attorneys including in-house counsel) incurred by Lessor in connection
with any proposed or purported Transfer shall be borne by Lessee and shall be
payable to Lessor as additional Rent.

               (d) Without conferring any rights upon Lessee not otherwise
provided in this Section 7, in the event of a Transfer fifty percent (50%) of
the excess of any monthly base rent or other payment or consideration accruing
to the Lessee as a result of such Transfer (including, but not limited to, any
lump sum or periodic payment in any manner relating to such Transfer) above the
Monthly Base Rent payable by Lessee with respect to that portion of the Demised
Premises, shall, after deduction of Lessee's reasonable out-of-pocket costs for
brokerage commissions and tenant improvements paid by Lessee in connection with
such Transfer (such costs to be amortized on a straight-line basis over the term
of any sublease), be paid by Lessee to Lessor within ten (10) days following
receipt thereof by Lessee, as additional Rent.

               (e) If Lessee is a corporation, then the sale, issuance or
transfer of any voting capital stock of Lessee or of any corporate entity which
directly or indirectly controls Lessee 

                                       6
<PAGE>   7

(unless Lessee is a corporation whose stock is traded on the New York Stock
Exchange or the American Stock Exchange or a recognized national
"over-the-counter" exchange) which shall result in a change in the voting
control of Lessee or the corporate entity which controls Lessee shall be deemed
to be an assignment of this Lease within the meaning of this Section 7. If
Lessee is a partnership or an unincorporated association, then the sale,
issuance or transfer of a majority interest therein, or the transfer of a
majority interest in or a change in the voting control of any partnership or
unincorporated association or corporation which directly or indirectly controls
Lessee, or the transfer of any portion or all of any general partnership or
managing partnership interest, shall be deemed to be an assignment of this Lease
within the meaning of this Section 7. Any attempted or purported Transfer in
violation of the foregoing, whether voluntary or involuntary or by operation of
law or otherwise, shall be null and void and shall not confer any rights upon
any purported Transferee, and shall, at Lessor's option, terminate this Lease
without relieving Lessee of any of its obligations hereunder for the balance of
the stated Term.

               (f) Notwithstanding anything herein contained to the contrary,
the co-location of customer equipment in the Demised Premises in the ordinary
course of Lessee's business shall not be deemed to be an assignment or
subletting. However, Lessee shall be solely responsible for all risk of loss or
damage to any such equipment, and shall be solely responsible for any and all
loss or damage occasioned by the installation, operation, repair, maintenance
and/or removal of such equipment.

8.      MAINTENANCE BY LESSEE

        Lessee, subject to Sections 9, 10, and 20, at its cost shall keep the
Demised Premises and the fixtures and equipment therein in clean, safe and
sanitary condition, will take good care thereof, will suffer no waste or injury
thereto, and will, at the expiration or other termination of the term of this
Lease, surrender the same, broom clean, in the same order and condition in which
they are on the Commencement Date, ordinary wear and tear and damage by the
elements, fire and other casualty not due to the intentional or negligent acts
or omissions of Lessee or Lessee's agents, employees, contractors, licensees or
invitees, excepted; and upon such termination of this Lease, Lessor shall have
the right to re-enter and resume possession of the Demised Premises. It is
hereby understood and acknowledged by the parties hereto that, except as
expressly set forth in the Lease, Lessor is leasing the Demised Premises to
Lessee in "as is" condition with all faults, and that Lessor has made no
representations respecting the conditions of the Demised Premises or the
Property not expressly contained herein. Except as expressly set forth herein,
Lessor shall have no liability to Lessee or any of Lessee's directors, officers,
employees, agents, contractors, licensees or invitees arising from the condition
of the Property or the Demised Premises, and Lessee shall defend, indemnify and
hold Lessor harmless from and against any claims, causes of action, damages and
liability arising therefrom. The foregoing indemnity shall be deemed to survive
the expiration of this Lease.

9.      ALTERATIONS

               (a) Lessee will not make or permit any alterations, decorations,
additions or improvements, structural or otherwise, in or to the Demised
Premises or the Building, without the prior written consent of Lessor, which
consent may be conditioned upon Lessee's agreement to remove the same and
restore the Demised Premises to its condition prior to the making of such
alterations, at Lessee's sole cost and expense, upon the expiration or sooner
termination of this Lease. Lessor hereby grants Lessee the right to install (i)
a Kastle card reader at the suite entry door to the Demised Premises, (ii) a
supplemental heating, ventilation and air conditioning system package, and (iii)
a supplemental fire suppression system in the Demised Premises, subject to the
following terms and conditions:

        (A) Lessee shall submit to Lessor in advance of each such installation,
for Lessor's approval, complete plans and specifications for such installation;

        (B) All such installations shall be performed in accordance with all
applicable laws, regulations and codes, and otherwise in compliance with all
applicable terms and conditions of this Lease (including, but not limited to,
this Section 9) and with such other reasonable restrictions and conditions as
Lessor may impose with regard thereto, all at Lessee's sole cost and expense.
Without limiting the foregoing, Lessee shall be solely responsible for causing
any 

                                       7
<PAGE>   8

HVAC equipment installed by Lessee to be separately metered for electricity and
water, and Lessee shall pay to Lessor the metered cost of consumption of such
utilities;

        (C) Lessee shall, prior to commencing such installation work, procure
all approvals, licenses, permits and other required authorizations from the
applicable governmental authorities as required to perform such installations;

        (D) Lessee shall further obtain and maintain in full force and effect
throughout the Lease Term all approvals, licenses, permits and other required
authorizations (including, but not limited to, any periodic inspections of the
same) from the applicable governmental authorities as are required to maintain
and operate such installations;

        (E) Upon the expiration of the Lease Term, or any earlier day on which
removal may be required in order to comply with any applicable law, regulation,
code or order, Lessee shall remove such installations and shall restore the
Demised Premises to its condition prior to the performance of such
installations, all at Lessee's sole cost and expense; provided that, Lessor
shall have the right, to be exercised by written notice to Lessee prior to the
expiration of the Lease Term and without payment of compensation or other
consideration, to require that such installations remain upon the Demised
Premises at the expiration of the Lease Term;

        (F) Lessee shall obtain and maintain throughout the Lease Term all
necessary policy endorsements required to insure against any and all costs,
claims, expenses, fees, liabilities, loss, suits or damages which may be
occasioned by the installation, operation, maintenance, repair and/or removal of
such installations; and

        (G) Lessor shall have no liability, and Lessee hereby relieves and
releases Lessor from any and all liability, with respect to the proper
functioning of, or any loss or damage to, such installations. Lessee shall and
does hereby undertake to defend, indemnify and hold Lessor and the Property
harmless from and against any and all claims, costs, damages, expenses, fees,
liabilities, losses and suits which may arise, directly or indirectly, from or
out of, or in connection with, the installation, operation, maintenance, repair
and/or removal of such installations, including, but not limited to, any bodily
injury, damage, loss or loss of use of property, and any third party liability
which Lessor may suffer or incur, whether due to an accidental release or
otherwise.

               (b) If any mechanic's lien is filed against the Demised Premises,
or the real property of which the Demised Premises are a part, for work claimed
to have been done for, or materials claimed to have been furnished to, Lessee,
such mechanic's lien shall be discharged by Lessee within ten (10) days
thereafter, at Lessee's sole cost and expense, by the payment thereof or by
filing any bond required by law. Lessee shall promptly inform Lessor upon
receipt, by Lessee, of any notice of the filing of any such mechanics lien(s).
If Lessee shall fail to discharge any such mechanic's lien, Lessor may, at its
option and without inquiring into the validity thereof discharge the same and
treat the cost thereof as additional Rent payable with the monthly installment
of Rent next becoming due; it being hereby expressly covenanted and agreed that
such discharge by Lessor shall not be deemed to waive, or release, the default
of Lessee in not discharging the same. Lessee hereby covenants and agrees to
defend, indemnify /and hold Lessor, the Demised Premises and the property upon
which the Demised Premises is constructed, harmless from and against any and all
claims, damages, cost, expense, liability, liens and other detriment which they
may suffer or which may arise by reason of the making of any such alterations,
decorations, additions or improvements. If any such alteration, decoration,
addition or improvement is made without the prior written consent of Lessor,
Lessor may correct or remove the same, and Lessee shall be liable for any and
all expenses incurred by Lessor in the performance of this work. All
alterations, decorations, additions or improvements in or to the Demised
Premises made by either party shall immediately become the property of Lessor
and shall remain upon and be surrendered with the Demised Premises as a part
thereof at the end of the Lease Term without disturbance, molestation or injury;
provided, however, that if Lessee is not in default in the performance of any of
its obligations under this Lease, Lessee shall have the right to remove, prior
to the expiration or termination of the Lease Term, all movable furniture,
furnishings or equipment installed in the Demised Premises at the expense of
Lessee, and if such property of Lessee is not removed by Lessee prior to the
expiration or termination of this Lease the same shall become the property of
Lessor and shall be surrendered with the Demised 

                                       8

Premises as a part thereof. Should the Lessor elect that alterations,
decorations, additions or improvements upon the Demised Premises be removed,
upon termination of this Lease or upon termination of any renewal period hereof,
Lessee hereby agrees to cause same to be removed at Lessee's sole cost and
expense and should Lessee fail to remove the same, then and in such event, the
Lessor shall cause same to be removed at the Lessee's expense and the Lessee
hereby agrees to reimburse the Lessor for the cost of such removal together with
any and all damages which the Lessor may suffer and sustain by reason of the
failure of Lessee to remove the same.

10.     TENANT WORK

               (a) Promptly following the execution hereof, Lessor shall cause
Lessor 5 architect to prepare construction drawings and specifications for the
improvements to the Demised Premises which are consistent with the Tenant
Workletter attached as Exhibit B, and preliminary space plan attached as Exhibit
B-l. Following preparation of such construction drawings and specifications,
Lessor shall cause Lessor's general contractor to perform in the Demised
Premises the leasehold improvements shown on such final construction drawings
and specifications (the "Initial Improvements") . In no event shall the Initial
Improvements include any work to the Demised Premises not set forth in the final
construction drawings and specifications as approved by Lessor, nor shall Lessor
have any obligation to do any work to the Demised Premises not included in the
Initial Improvements.

               (b) The Initial Improvements shall be performed by Lessor at
Lessor's sole cost; provided that, Lessee shall reimburse Lessor for any costs
incurred in connection with the design or performance of the Initial
Improvements to the extent attributable to, or occasioned by, a Lessee Delay or
work which is beyond the scope of the Initial Improvements set forth on Exhibit
B-l.

               (c) Lessee may undertake to have extra tenant work performed at
its own expense, provided, that (i) the design of all such work and
installations shall be subject to the prior written approval of Lessor and
Lessor's architect or supervising engineer, (ii) no work may be commenced until
the written approval of Lessor is obtained, (iii) all work must be performed in
accordance with tenant work procedures promulgated by Lessor, (iv) Lessee will
not make any structural modifications (the term "structural" as used herein
being given the widest possible application and to include, but not be limited
to, the roof, all load bearing walls, all exterior walls, membranes and glass
lines, all concrete floor and roof slabs, and all electrical, plumbing, heating,
ventilation, air conditioning and other mechanical systems), (v) Lessee will
obtain a building permit for said work and will deliver one set of approved
plans as well as final inspection stickers and occupancy certificate to Lessor,
and (v) all work must be performed by a contractor approved by Lessor. In
addition, Lessee's contractor, if other than Lessor or Lessor's Contractor, is
to be bonded if the total cost of the proposed improvements exceeds $10,000.00;
(ii) Lessee shall comply with all such other reasonable restrictions and
conditions as Lessor may impose; (iii) Lessee shall discharge all mechanics'
liens in accordance with Section 9(b); and (iv) Lessee will defend, indemnify
and hold Lessor and Lessor's Property harmless from and against all damage and
liability arising from the making of any such leasehold improvements.

               (d) As used in this Lease, "Lessee Delays" shall mean delays in
Lessee's providing Lessor with information or approvals relevant to planning or
constructing the Initial Improvements following written notice requesting such
information or approvals, and delays in the performance of the Initial
Improvements caused by change orders requested by Lessee (including any changes
in the construction plans and specifications) or other acts or omissions of
Lessee or Lessee's agents, contractors, employees or others for whose actions
Lessee is responsible.

11.     SIGNS, SAFES & FURNISHINGS

        No signs, advertisement or notice shall be inscribed, painted, affixed
or displayed on any part of the outside or the inside of the Building except on
the directories and the doors of offices, and then only in such place, number,
size, material color and style as is approved by Lessor, and if any such sign,
advertisement or notice is exhibited, Lessor shall have the right to remove the
same and Lessee shall be liable for any and all expenses incurred by Lessor by
said removal, Lessee hereby agreeing to reimburse Lessor upon demand for all
such expenses incurred by 

                                       9
<PAGE>   10

Lessor. Any such permitted use, including directories and name plates, shall be
at the sole expense and cost of the Lessee. Lessor shall have the right to
prohibit any advertisement of Lessee which in its opinion tends to impair the
reputation of the Building or its desirability as a high-quality office
Building, and, upon written notice from Lessor, Lessee shall immediately refrain
from and discontinue any such advertisement. Lessor shall have the right to
prescribe the weight and position of safes and other heavy equipment or
fixtures. Any and all damages or injury to the Demised Premises or the Building
caused by moving the property of Lessee into, or out of the Demised Premises, or
due to the same being on the Demised Premises, shall be repaired by, and at the
sole cost of, Lessee. No furniture, equipment or other bulky matter of any
description will be received into the Building or carried in the elevators
except as approved by Lessor. All moving of furniture, equipment and other
material within the public areas shall be subject to such conditions and
restrictions as may be imposed by Lessor, who shall, however, not be responsible
for any damage to or charges for moving the same. Lessee agrees promptly to
remove from the sidewalks adjacent to the Building any of the Lessee's
furniture, equipment or other material there delivered or deposited.

12.     ENTRY FOR REPAIRS AND INSPECTIONS

        Lessor hereby reserves the right, for itself and its agents, officers,
employees and contractors, to have access to the Demised Premises at all
reasonable times upon not less than twenty-four (24) hours verbal notice (except
in the event of an emergency, in which event no notice shall be required) to
examine, inspect, and protect the same and to prevent damage or injury to the
same; to make such alterations and repairs to the Demised Premises, the Building
or other premises as the Lessor may deem necessary; to exhibit the same to
potential or actual mortgagees or purchasers of said Building; and during the
last six (6) months of the Lease Term, to exhibit the same to prospective
tenants. No such access by Lessor or those claiming by or through Lessor shall
constitute a constructive eviction or a basis for an abatement of Rent, nor
shall Lessee be entitled to any compensation on account thereof. Lessor shall
exercise reasonable efforts to give Lessee prior notice of such access, and,
when making such access, to minimize the interference with Lessee's business
operations; provided, however, the foregoing shall not be construed to require
Lessor to limit such access to non-business hours or to limit the number of
persons permitted access to the Demised Premises hereunder.

13.     INSURANCE RATING

        Lessee will not conduct or permit to be conducted any activity, or place
any equipment in or about the Demised Premises, which will, in any way, increase
the rate of fire insurance or other insurance on the Building; and if any
increase in the rate of fire insurance or other insurance is stated by any
insurance company or by the applicable Insurance Rating Bureau to be due to
activity or equipment in or about the Demised Premises, such statement shall be
conclusive evidence that the increase in such rate is due to such activity or
equipment and, as a result thereof, Lessee shall be liable for such increase as
additional Rent and upon notification thereof by Lessor shall reimburse Lessor
therefore.

14.     LESSEE'S EQUIPMENT

        Lessee will not install or operate in the Demised Premises any
electrically operated equipment or other machinery, other than electric
typewriters, adding machines, radios, televisions, tape recorders, dictaphones,
bookkeeping machines, telefax machines, personal computers and associated
peripheral equipment, copy machines, coffee machines, microwave ovens and
clocks, without first obtaining the prior written consent of Lessor who may
condition such consent upon the payment by Lessee of additional Rent in
compensation for such excess consumption of the utilities, for additional wear,
tear or depreciation to base Building equipment occasioned from such usage, and
for the cost of additional wiring as may be occasioned by the operation of said
equipment of a kind or nature whatsoever which will or may necessitate any
changes, replacements or additions to, or in the use, the water system, heating
system, plumbing system, air-conditioning system, or electrical system of the
Demised Premises or the Building. Business machines and mechanical equipment
belonging to Lessee which cause noise or vibration that may be transmitted to
the structure of the Building or to any space therein to such a degree as to be
objectionable to Lessor or to any tenant in the Building shall be Installed and


                                       10
<PAGE>   11

maintained by Lessee, at Lessee's expense, on vibration eliminators or other
devices sufficient to eliminate such noise and vibration.

15.     INDEMNITY

        Lessee will defend, indemnify and hold harmless Lessor from and against
any loss, damage or liability (including attorneys fees) occasioned by or
resulting from any default hereunder or any willful or negligent act or omission
on the part of Lessee, its agents, employees, invitees, licensees, contractors
or persons permitted in the Building or on the Demised Premises by Lessee.

16.     SERVICES AND UTILITIES

        Lessor shall furnish reasonably adequate electricity, water, lavatory
supplies, and automatically operated elevator service and normal and customary
cleaning and char service for comparable Tysons Corner buildings (on a five (5)
day week basis exclusive of legal holidays) after business hours. Lessor shall
furnish hot and cold water at those points of supply provided for general use of
other tenants in the Building, central heat and air-conditioning in season, at
such times as Lessor normally furnishes these services to other tenants in the
Building, and at such temperatures and in such amounts as are considered by
Lessor to be standard, Monday through Friday, from 8 a.m. to 6 p.m. and on
Saturday from 8 a.m. to 1 p.m. exclusive of Sundays and holidays during such
seasons of the year when such services are normally and usually furnished in the
modern office buildings in the Washington, D.C. metropolitan area; routine
maintenance, painting and electric lighting service for all public areas, garage
and special service areas of the Building in the manner and to the extent deemed
by Lessor to be standard; proper electrical facilities to furnish sufficient
power to machines of low electrical consumption provided, however, that, except
for reasonable quantities of low electrical consumption equipment which Lessee
is permitted to install in the Demised Premises pursuant to Section 14 without
Lessor's consent, Lessee shall bear the utility costs occasioned by electro-data
processing machines, including air-conditioning costs therefor, mini computers,
mainframe computers and similar machines of high electrical consumption; all
subject to Federal, State and County governmental controls and regulations; but
failure by Lessor to any extent to furnish these defined services, or any
cessation thereof, resulting from causes beyond the control of Lessor, shall not
render Lessor liable in any respect for damages to either person or property,
nor be construed as an eviction of Lessee, nor work an abatement of Rent, nor
relieve Lessee from fulfillment of any covenant or agreement hereof. Should any
of the Building equipment or machinery break down, or for any cause cease to
function properly, Lessor shall, upon receipt of notice from Lessee of the need
therefore, use reasonable diligence to repair the same promptly, but Lessee
shall have no claim for rebate of Rent or damages on account of any
interruptions in service occasioned thereby or resulting therefrom. Subject to
the terms hereof, regular maintenance and repairs, and circumstances and events
beyond the reasonable control of Lessor, Lessee and Lessee's employees shall
have access to the Building and the Demised Premises twenty-four (24) hours per
day, three hundred sixty-five (365) days per year.

        Subject to the terms hereof, regular maintenance and repairs, and
circumstances and events beyond the reasonable control of Lessor, Lessor shall
provide heat and air conditioning at times in addition to those specified above,
at Lessee's expense upon not less than twenty-four (24) hours written notice
from Lessee, but in no event shall notice be provided later than 11:00 a.m. on a
Friday for weekend or holiday overtime operation. Lessee shall pay Lessor for
said after-hours service based upon Lessor's building standard service charge
then-in effect and subject to change from time to time (currently Nineteen
Dollars ($19.00) per hour per floor), plus Lessor's additional charge as then-in
effect and subject to change from time to time (currently Thirty Dollars
($30.00) per hour (regardless of the number of floors)) when an engineer's
presence is required or requested by Lessee. The foregoing charges shall be
subject to annual revision by Lessor.

        Notwithstanding anything herein contained to the contrary, Lessee shall
reimburse Lessor upon demand for all electrical consumption and demand charges
attributable to electricity provided through the sub-panel installed by Lessor
in the Demised Premises, or otherwise provided for or consumed by any
supplemental heating, ventilation and air conditioning equipment or other
equipment installed by or on behalf of Lessee. Without limiting the

                                       11
<PAGE>   12

foregoing, Lessee shall reimburse Lessor for all such electrical usage,
including demand and consumption charges attributable to such usage (Lessee
hereby acknowledging and agreeing that Lessee shall bear demand charges
attributable to electricity consumption during summer peak months, even though a
portion of such demand changes may be imposed during the nine (9) months after
such summer peak months) based on a sub-metered calculation of such usage.

17.     RESPONSIBILITY FOR CERTAIN DAMAGE AND BREAKAGE

        All injury to the Demised Premises or the Building of which they are a
part, and all breakage and damage done by Lessee or the agents, servants,
licensees, contractors, employees and visitors of Lessee, shall be repaired
promptly by the Lessee, at the expense of the Lessee. In the event that the
Lessee shall fail so to do, then the Lessor shall have the right to make
necessary repairs, alterations and replacements, structural, non-structural, or
otherwise, and any charge or cost so incurred by the Lessor shall be paid by the
Lessee with the right on the part of the Lessor to elect in its discretion to
regard the same as additional Rent, in which event such cost or charge shall
become additional Rent payable with the installment of Monthly Base Rent next
becoming due or thereafter falling due under the terms of this Lease. This
provision shall be construed as an additional remedy granted to the Lessor and
not in limitation of any other rights and remedies which the Lessor has or may
have in said circumstances. The exercising of Lessor's right to cure will not
excuse the failure of Lessee to perform its obligations hereunder.

18.     BANKRUPTCY

               (a) If at any time during the Lease Term, a petition shall be
filed, either by or against the Lessee, in any Court or pursuant to any Federal,
State, or Municipal statute whether in bankruptcy, insolvency, for the
appointment of a receiver of the Lessee's property or because of any general
assignment made by the Lessee of the Lessee's property for the benefit of the
Lessee's creditors, then immediately upon the happening of any such event, and
without any entry or other act by the Lessor, this Lease, at Lessor's option,
shall cease and come to an end with the same force and effect as if the date of
the happening of any such event were the date herein fixed for the expiration of
the Lease Term. It is further stipulated and agreed that, in the event of the
termination of the Lease Term by the happening of any such event, the Lessor
shall forthwith, upon such termination, and any other provisions of this Lease
to the contrary notwithstanding, become entitled to recover as and for
liquidated damages caused by such breach of the provisions of this Lease, an
amount equal to the difference between the then cash value of the Rent reserved
hereunder for the unexpired portion of the term and the then cash rental value
of the Demised Premises for such unexpired portion of the Lease Term hereby
demised, unless the statute which governs or shall govern the proceeding in
which such damages are to be proved limits or shall limit the amount of such
claim capable of being so proved, in which case the Lessor shall be entitled to
prove as and for liquidated damages an amount equal to that allowed by or under
any such statute. The provisions of this Section of this Lease shall be without
prejudice to the Lessor's right to prove in full damages for Rent accrued prior
to the termination of this Lease, but not paid. This provision of this Lease
shall be without prejudice to any rights given to the Lessor by any pertinent
statute to prove any amounts allowed thereby.

               (b) In making any such computation, the then cash rental value of
the Demised Premises shall be deemed prima-fade to be the present cash value
(utilizing a 6% discount rate) of rental realized upon any re-letting, if such
re-letting can be accomplished by the Lessor within a reasonable time after such
termination of this Lease, and the then present cash value of the future Rents
hereunder reserved to the Lessor for the unexpired portion of the term hereby
demised shall be deemed to be such sum, if invested at six per cent (6%) simple
interest, as will produce the future Rent over the period of time in question.

19.     LIABILITY FOR DAMAGE TO PERSONAL PROPERTY AND PERSON

        All personal property of the Lessee, its employees, agents, business
invitees, licensees, customers, clients, family members, guests or trespassers
in and on said Demised Premises, shall be and remain at their sole risk, and
Lessor shall not be liable to them for any damage to, or loss of such personal
property arising from any act of negligence of any other persons nor from the
leaking of the roof, or from the bursting, leaking or overflowing of water,
sewer or steam pipes, or from heating or plumbing fixtures, or from electrical
wires or fixtures, or from air-

                                       12
<PAGE>   13

conditioning failure, or from any other cause whatsoever, nor shall the Lessor
be liable for the interruption or loss to Lessee's business arising from any of
the above described acts or causes, nor shall the Lessor be liable for any
personal or bodily injury to the Lessee, its employee, agents, business
invitees, licensees, contractors, customers, clients, family members, guests or
trespassers arising from the use, occupancy and condition of the Demised
Premises or Building; the Lessee especially agreeing to defend, indemnify and
save the Lessor harmless in all such cases from and against any loss, damage, or
liability (including attorney's fees) arising therefrom.

20.     DAMAGE TO THE DEMISED PREMISES

        If the Demised Premises shall be damaged by fire or other cause without
the fault or neglect of Lessee, Lessor shall diligently and as soon as
practicable after such damage occurs (taking into account the time necessary to
effectuate a satisfactory settlement with any insurance company) repair such
damage (but excluding Lessee's furniture, fixtures, furnishings, equipment,
improvements and/or alterations) at the expense of the Lessor, and the Monthly
Base Rent shall be reduced in proportion to the extent the Demised Premises are
rendered untenantable, until such repairs are completed, provided, however, that
if the Building is damaged by fire or other cause to such extent that the damage
cannot be fully repaired within sixty (60) days from the date of such damage,
Lessor shall have the option of terminating this Lease by giving written-notice
to Lessee of such decision and the Lease Term shall terminate on the day such
notice is given. Notwithstanding the foregoing, in the event the Building shall
be damaged or destroyed by fire or other casualty during the last twelve (12)
months of the Lease Term, Lessor shall have no obligation to rebuild the Demised
Premises, and upon giving Lessee notice of Lessor's election not to rebuild the
Demised Premises, this Lease shall cease and determine as fully as if the date
of such notice were the scheduled termination date of this Lease. No
compensation or claim or reduction of Rent will be allowed or paid Lessor by
reason of inconvenience, annoyance, or injury to business arising from the
necessity of repairing the Demised Premises or any portion of the Building
however the necessity may occur.

21.     DEFAULT OF LESSEE

        If (I) Lessee shall fail to pay any monthly installment of Monthly Base
Rent or any other Rent as reserved hereunder when and as the same are due
(although no legal or formal demand shall have been made therefor), or (ii)
Lessee shall violate or fail to perform any of the other conditions, covenants
or agreements herein made or imposed upon Lessee, and such violation or failure
shall continue for a period of ten (10) days after written notice thereof to
Lessee from Lessor (provided that, for any default which cannot reasonably be
cured within said ten (10) day period, the cure period therefor shall be
extended for such time as is reasonably necessary to effect a cure of such
default (but in no event beyond forty-five (45) days after delivery of notice of
such default), on the conditions that Lessee immediately commences to cure such
default and diligently pursues such cure to completion, and that, promptly upon
determining that the aforesaid ten (10) day cure period is inadequate, Lessee
shall deliver notice to Landlord of the steps being taken to cure such default
and the amount of time reasonably estimated by Lessee to effect such cure; but
provided further that, no notice or cure period shall be required to be provided
with regard to any intentional or willful default by Lessee hereunder, or with
regard to any default which (A) by its nature cannot be cured (or cannot be
cured within the aforesaid forty-five (45) day period), (B) constitutes a hazard
to the health and/or safety of any occupant of the Property, (C) has caused the
insurer of any policy of insurance on the Property to issue a notice of
cancellation of such policy, (D) involves the failure by the Lessee to maintain
any insurance required to be maintained by Lessee hereunder, or (E) subjects
Landlord to the risk of civil or criminal liability, fine, penalty or
prosecution), or (iii) if (a) Lessee becomes "insolvent," as defined in Title 11
of the United States Code, entitled "Bankruptcy," 11 U.S.C. Section 101, et seq.
(the "Bankruptcy Code"), or under the insolvency laws of any State, District,
Commonwealth or Territory of the United States of America ("Insolvency Laws"),
(b) a receiver or custodian is appointed for any or all of Lessee's property or
assets, or if there is instituted a foreclosure action on any of Lessee's
property, (c) Lessee files a voluntary petition under the Bankruptcy Code or any
Insolvency Laws, (d) there is filed an involuntary petition against Lessee as
the subject debtor under Bankruptcy Code or any Insolvency Laws, which such
petition is not dismissed within thirty (30) days of filing or results in
issuance of an order for relief against the Lessee as debtor, or (e) Lessee
makes or consents to an assignment of its assets, 

                                       13
<PAGE>   14
in whole or in part, for the benefit of creditors, or a common law composition
of creditors, or (iv) the Demised Premises being abandoned, vacant or deserted
and remaining so for five (5) days (provided that, vacating the Demised Premises
shall not constitute a default hereunder, so long as (A) Lessee shall notify
Lessor not less than ten (10) days in advance of vacating the Demised Premises
that Lessee intends to vacate the Demised Premises, (B) Lessee shall obtain and
maintain in full force and effect such insurance endorsements as shall be
required in order to assure that all insurance required to be maintained by
Lessee hereunder shall remain in force notwithstanding that Lessee has vacated
the Demised Premises, and (C) Lessee shall take all commercially reasonable
steps necessary to ensure that the Demised Premises are secure against
unauthorized entry during such period(s) as the Demised Premises shall remain
vacant), then and in any of said events this Lease shall, at the option of
Lessor, cease and terminate and shall operate as a notice to quit, ANY NOTICE TO
QUIT OR OF LESSOR'S INTENTION TO RE-ENTER BEING HEREBY EXPRESSLY WAIVED, and
Lessor may proceed to recover possession under and by virtue of the provisions
of the laws of the State of Virginia, or by such other proceedings, including
re-entry and possession, as may be applicable. If Lessor elects to terminate
this Lease, everything herein contained on the part of Lessor to be done and
performed shall cease without prejudice, however, to the right of Lessor to
recover from Lessee all Rent accrued up to the time of termination or recovery
of possession by Lessor, whichever is later. Upon the occurrence of an event of
default as aforesaid, at Lessor's option (either with or without terminating
this Lease), the Demised Premises may be relet by Lessor for such Rent and upon
such terms as Lessor, in Lessor's sole discretion, shall deem appropriate under
the circumstances, and, if the full Rent hereinabove provided shall not be
realized by Lessor, Lessee shall be liable for all damages sustained by Lessor,
including, without limitation, deficiency in Rent, reasonable attorneys' fees,
brokerage fees, and expenses of placing the Demised Premises in first class
rentable condition. Any damage or loss of Rent sustained by Lessor may be
recovered by Lessor at Lessor's option, at the time of the re-letting, or in
separate actions, from time to time, as said damage shall have been made more
easily ascertainable by successive re-lettings, or, at Lessor's option, may be
deferred until the expiration of the Lease Term, in which event the cause of
action shall not be deemed to have accrued until the date of expiration of said
Lease Term. If Lessor should commence any summary proceeding for non-payment of
Rent by Lessee or to recover possession of the Demised Premises, Lessee shall
not interpose any counterclaim of any nature or description in any such
proceeding. Upon the occurrence of an event of default hereunder, provided this
Lease shall not be terminated, Lessor shall, in addition, have the option to
either (I) declare the Rent reserved for the next succeeding six (6) months (or
such lesser period as Lessor deems appropriate) immediately due and payable, or
(ii) require Lessee to deposit with Lessor an additional Security Deposit in an
amount not to exceed six (6) months' Monthly Base Rent. The provisions contained
in this Section shall be in addition to and shall not prevent the enforcement of
any claim Lessor may have against Lessee for anticipatory breach of the
unexpired Lease Term. In the event that Lessee continues to occupy the Demised
Premises after the expiration of the Lease Term, with the express or implied
consent of Lessor, such tenancy shall be from month to month and shall not be a
renewal of the term of this Lease or a tenancy from year to year. All rights and
remedies of Lessor under this Lease shall be cumulative and shall not be
exclusive of any other rights and remedies provided to Lessor under applicable
law.

22.     WAIVER

        If under the provisions hereof Lessor shall institute proceedings and a
compromise or settlement thereof shall be made, the same shall not constitute a
waiver of any covenant herein contained nor of any of Lessor's rights hereunder.
No waiver by Lessor of any breach of any covenant, condition or agreement herein
contained shall operate as a waiver of such covenant, condition, or agreement
itself, or of any subsequent breach thereof. No payment by Lessee or receipt by
Lessor of a lesser amount than the Rent herein stipulated shall be deemed to be
other than on account of the earliest stipulated Rent nor shall any endorsement
or statement on any check or letter accompanying a check for payment of Rent be
deemed an accord and satisfaction and Lessor may accept such check or payment
without prejudice to Lessor's right to recover the balance of such Rent or to
pursue any other remedy provided in this Lease. No re-entry by Lessor, and
acceptance by Lessor of keys from Lessee, shall be considered an acceptance of a
surrender of the Lease.

                                       14
<PAGE>   15

23.     SUBORDINATION

        This Lease is and shall automatically be subject and subordinate to the
lien of any and all mortgages (which term "mortgage" shall include both
construction and permanent financing and shall include deeds of trust and
similar security instruments) which may now or hereafter encumber or otherwise
affect the real estate (including the Building) of which the Demised Premises
form a part, or Lessor's interest therein, and to all and any renewals,
extensions, modifications, recastings or refinancings thereof. In confirmation
of such subordination, Lessee shall, at Lessor's request, promptly execute any
requisite or appropriate certificate or other document. Lessee hereby
constitutes and appoints Lessor as Lessee's attorney-in-fact to execute any such
certificate or certificates for or on behalf of Lessee, in the event Lessee
fails to execute and return the same within ten (10) days after delivery of
Lessor's request. Notwithstanding anything to the contrary set forth above, any
beneficiary under any mortgage shall have the right, at its election (which
election may be exercised unilaterally by said beneficiary executing and filing
a notice thereof for record with the Clerk of the Circuit Court of Fairfax
County, Virginia, at any time prior to said beneficiary commencing foreclosure
Proceedings pursuant to such mortgage) to subordinate the lien of such mortgage
to the Lease to the extent set forth in such document and thereupon the Lease
shall be deemed prior to such mortgage to the extent set forth in such document
without regard to their respective dates of execution, delivery and/or
recording. In that event, to the extent set forth in such document, such
mortgage shall have the same rights with respect to this Lease as would have
existed if this Lease had been executed, and a memorandum thereof recorded prior
to the execution, delivery and recording of the mortgage. Lessee agrees that in
the event that any Proceedings are brought for the foreclosure of any such
mortgage, Lessee shall attorn to the purchaser at such foreclosure sale, if
requested to do so by such purchaser and to recognize such purchaser as the
Lessor under this Lease, and Lessee waives the provisions of any statute or rule
of law, now or hereafter in effect, which may give or purport to give Lessee any
right to terminate or otherwise adversely affect this Lease and the obligations
of Lessee hereunder in the event that any such foreclosure proceeding is
prosecuted or completed. Any mortgagee, purchaser at foreclosure, or assignee of
Lessor who requests such attornment shall not (a) be bound by any prepayment of
Rent for more than one (1) month in advance (Lessee hereby acknowledging and
agreeing that Lessee shall have no right to, and shall not, prepay Rent more
than one month in advance of its due date, and that Rent shall be payable after
any such foreclosure, purchase, or assignment, in case of a requested attornment
as aforesaid, in accordance with the provisions of this Lease as if such
prepayment of Rent for more than one (1) month in advance had not been made),
nor (b) to be bound by any amendment to this Lease which was not approved by
such mortgagee prior to the foreclosure or assignment, nor (c) be subject to any
defense which Lessee might assert against Lessor, nor (d) be liable for any
defaults (including defaults of a continuing nature) by any prior landlord,
including the Lessor, or for the return of any security deposit except to the
extent the mortgagee or such purchaser actually received the same, in cash or in
kind, and such security deposit has been segregated and identified as such by
Lessor in the ordinary course of business.

24.     CONDEMNATION

        If the whole or a substantial part of the Demised Premises shall be
taken or condemned (the terms "taken" and "condemned" as used herein being
deemed to include any deed given in lieu of or under threat of taking or
condemnation) by any governmental or quasi-governmental authority for any public
or quasi-public use or purpose, then the Lease Term shall cease and terminate as
of the date when title vests in such condemning authority, and Lessee shall have
no claim against Lessor or the condemning authority for any portion of the
amount that may be awarded as damages as a result of such taking or condemnation
or for the value of any unexpired portion of the Lease Term. The Monthly Base
Rent, however, shall be abated on the date when such title vests in such
condemning authority. If less than a substantial part of the Demised Premises is
taken or condemned by any governmental or quasi-governmental authority for any
public or quasi-public use or purpose, the Monthly Base Rent shall be equitably
adjusted on the date when title vests in such condemning authority and the Lease
shall otherwise continue in full force and effect. For purpose of the Article, a
substantial part of the Demised Premises shall be considered to have been taken
if more than fifty percent (50%) of the Demised Premises are untenantable by
Lessee.

25.     RULES AND REGULATIONS

        Lessee shall, and shall cause Lessee's employees, agents, officers,
contractors, licensees and invitees to, abide by and observe the rules and
regulations attached hereto as Exhibit C. Lessee, its agents and employees,
contractors, licensees and invitees shall abide by and observe such other rules
or regulations as may be promulgated from time to time by Lessor for the
operation and maintenance of the Building provided that the same are in
conformity with common practice and usage in similar buildings and are not
inconsistent with the provisions of this Lease and a copy thereof is sent to
Lessee. Nothing contained in this Lease shall be construed to impose upon Lessor
any duty or obligation to enforce such rules and regulations, or the terms,
conditions or covenants contained in any other Lease as against any other
tenant, and Lessor shall not be liable to Lessee for violation of the same by
any other tenant, its employees, agents, business invitees, licensees,
customers, clients, family members or guests.

26.     RIGHT OF LESSOR TO CURE LESSEE'S DEFAULT

        If Lessee defaults in the making of any payment or in the doing of any
act herein required to be made or done by Lessee, then Lessor may, but shall not
be required to, make such payment or do such act, and the amount of the expense
thereof, if made or done by Lessor, with interest thereon at the rate of twelve
percent (12%) per annum from the date paid by Lessor, shall be paid by Lessee to
Lessor and shall constitute additional Rent hereunder due and payable with the
next monthly installment of Monthly Base Rent; but the making of such payment or
the doing of such act by Lessor shall not operate to cure such default or to
estop Lessor from the pursuit of any remedy to which Lessor would otherwise be
entitled. Any installment of Rent which is not paid by Lessee within ten (10)
days after the same becomes due and payable shall bear interest at the rate of
twelve percent (12%) per annum from the date such installment became due and
payable to the date of payment thereof by Lessee, plus a late charge of 10% of
the Rent payments not received by Lessor by the 10th of the month due, and such
interest and late charge shall constitute additional Rent hereunder due and
payable with the next monthly installment of Rent. The imposition of late
charges or interest will not be deemed to excuse the untimely payment of Rent.

27.     NO PARTNERSHIP

        Nothing contained in this Lease shall be deemed or construed to create a
partnership or joint venture of or between Lessor and Lessee, or to create any
other relationship between the parties hereto other than that of Lessor and
Lessee.

28.     NO REPRESENTATIONS BY LESSOR

        Neither Lessor nor any agent or employee of Lessor has made any
representations or promises with respect to the Demised Premises or the Building
except as herein expressly set forth, and no rights, privileges, easements or
licenses are granted to Lessee except as herein set forth. The Lessee, by taking
possession of the Demised Premises, shall accept the same "as is", and such
taking of possession shall be conclusive evidence that the Demised Premises and
the Building are in good and satisfactory condition at the time of such taking
of possession, as provided for in Exhibit D, subject to completion of mutually
agreed punch list items identified prior to Lessee's occupancy of the Demised
Premises.

29.     BROKERS

        Lessor and Lessee each represent and warrant one to another that except
as hereinafter set forth neither of them has employed any broker in carrying on
the negotiations relating to this Lease. Lessor shall indemnify and hold Lessee
harmless, and Lessee shall indemnify and hold Lessor harmless, from and against
any claim or claims for brokerage or other commission arising from or out of any
breach of their respective representation and warranty. Lessor recognizes
Barnes, Morris, Pardoe & Foster, Inc. as cooperating broker for this Lease and
Lessor agrees to pay said broker a leasing commission pursuant to a separate
cooperating brokerage agreement.

30.     WAIVER OF JURY TRIAL

        Lessor and Lessee hereby waive trial by jury in any action, proceeding
or counterclaim brought by either of the parties hereto against the other on or
in respect of any matter whatsoever arising out of or in any way connected with
this Lease, the relationship of Lessor and Lessee hereunder, Lessee's use or
occupancy of the Demised Premises' and/or claim of injury or damage.

31.     NOTICES

        All notices or other communications hereunder shall be in writing and
shall be deemed duly given when (a) if delivered in person (or attempted
delivery of the same if refused) or (b) deposited in the U.S. mails by certified
or registered mail, return receipt requested, addressed first-class, postage
prepaid, (i) if to Lessor, attention: Barry R. Gosnell, Gosnell Properties,
Inc., 8130 Boone Boulevard, Vienna, Virginia 22182, and (ii) if to Lessee, CRL
Network Services, Attention: Stacey Wright, One Kearny Street, Suite 1450, San
Francisco, California 94108, unless notice of a change of address is given

32.     ESTOPPEL CERTIFICATES

        Lessee agrees, at any time and from time to time, upon not less than ten
(10) days prior written notice by Lessor, to execute, acknowledge and deliver to
Lessor a statement in writing (i) certifying that this Lease is unmodified and
in full force and effect (or if there have been modifications, that the Lease is
in full force and effect as modified and stating the modifications), (ii)
stating the dates to which the Rent and other charges hereunder have been paid
by Lessee, (iii) stating whether or not to the best knowledge of Lessee, Lessor
is in default in the performance of any covenant, agreement or condition
contained in this Lease, and, if so, specifying each such default of which
Lessee may have knowledge, and (iv) stating the address to which notices to
Lessee should be sent and (v) such other information as Lessor may reasonably
request. Any such statement delivered pursuant hereto may be relied upon by any
owner of the Building, any prospective purchaser of the Building, any mortgagee
or prospective mortgagee of the Building or of Lessor's interest, or any
prospective assignee of any such mortgagee. Lessee hereby appoints Lessor as
Lessee's attorney-in-fact to execute and deliver any estoppel certificate which
Lessee fails to deliver to Lessor within ten (10) days of receipt of Lessor's
written request.

33.     HOLDING OVER

        In the event that Lessee shall not immediately surrender the Demised
Premises on the date of expiration of the term hereof, or any renewal term,
Lessee shall, by virtue of the provisions hereof, become a Lessee by the month
at the Monthly Base Rent in effect during the last month of the term of this
Lease plus twenty five percent (25%), which said monthly tenancy shall commence
with the first day next after the expiration of the Lease Term. The Lessee as a
monthly Lessee shall be subject to all of the conditions and covenants of this
Lease, except those provisions relating to Lessor funded tenant work, Rent
abatement or other Lessor funded allowances, as though the same had originally
been monthly tenancy. Lessee shall give to Lessor at least thirty (30) days'
written notice of any intention to quit the Demised Premises, and Lessee shall
be entitled to thirty (30) days' written notice to quit the Demised Premises,
EXCEPT IN THE EVENT OF NONPAYMENT OF RENT IN ADVANCE OR OF THE BREACH OF ANY
COVENANT BY THE LESSEE, IN WHICH EVENT LESSEE SHALL NOT BE ENTITLED TO ANY
NOTICE TO QUIT, THE USUAL THIRTY (30) DAYS' NOTICE TO QUIT BEING HEREBY
EXPRESSLY WAIVED. Notwithstanding the foregoing provisions of this Section, in
the event that Lessee shall hold over the expiration of the Lease Term hereby
created, and if Lessor shall desire to regain possession of the Demised Premises
promptly at the expiration of the Lease Term, then at any time prior to Lessor's
acceptance of Rent from Lessee as a monthly tenant hereunder, Lessor, at its
option, may forthwith re-enter and take possession of the Demised Premises
without process, or by any legal process in force in the State of Virginia, and
Lessee shall remain liable for any and all claims, cost, damage, expense and
liability which Lessor may suffer, to the extent that the same shall be
proximately caused by Lessee's failure to surrender the Demised Premises as
required hereunder.

34.     INTENTIONALLY OMITTED

35.     LIEN FOR RENT

        In consideration of the mutual benefits arising under this Lease, Lessee
hereby grants to Lessor a lien on all property of Lessee now or hereafter placed
in or on the Demised Premises (except such part of any property as may be
exchanged, replaced, or sold from time to time in the ordinary course of
business operation or trade) and such property shall be and remain subject to
such lien of Lessor for payment of all Rent and other sums agreed to be paid by
Lessee herein; provided that, Lessor hereby agrees to subordinate the lien
granted pursuant to this Section 35 to the lien of any properly perfected
purchase money security interest in equipment owned by Lessee which is placed in
the Demised Premises, and, with respect to leased equipment utilized by Lessee
in the Demised Premises, to the rights of the lessor in and to such equipment.
Lessee hereby covenants and agrees to execute and deliver to Lessor, upon
Lessor's request, a financing statement in form sufficient to perfect the
Lessor's security interest, as granted pursuant to this Section 35, in the
aforementioned property and proceeds pursuant to the provisions of the Uniform
Commercial Code as enacted in the Commonwealth of Virginia. Said lien shall be
in addition to and cumulative upon the Lessor's liens provided by law.

36.     PUBLIC LIABILITY INSURANCE

        Lessee shall obtain and maintain in effect at all times during the Lease
Term, a policy of comprehensive public liability insurance, naming Lessor, any
property management agent for the Building and any mortgagee of the Building as
additional insureds, protecting Lessor, Lessee, management agent and any such
mortgagee against any liability for bodily injury, death or property damage
occurring upon, in or about any part of the Building or the Demised Premises
arising from any of the items set forth herein against which Lessee is required
to indemnify Lessor, with such policies to afford protection to the limit of not
less than Five Hundred Thousand Dollars ($500,000) with respect to bodily injury
or death to any one person, to the limit of not less than One Million Dollars
($1,000,000), per occurrence and Two Hundred Fifty Thousand Dollars ($250,000)
with respect to damage to the property of any one owner. Lessor shall have the
right to require Lessee to increase the minimum limits of coverage set forth
above, from time to time, to the standard limits of coverage required in
comparable first class office Buildings in the Washington, D.C. area. Lessee, at
Lessee's sole cost and expense, shall obtain and maintain in effect commencing
with the Commencement Date and continuing through the Lease Term, insurance
policies providing for the following coverage: all risk and property insurance,
including (without limitation) coverage against fire, theft, vandalism,
malicious mischief, sprinkler leakage and such additional perils as now are or
hereafter may be included in a standard extended coverage endorsement from time
to time in general use in the Commonwealth of Virginia, insuring Lessee's
merchandise, trade fixtures, furnishings, equipment and all items of personal
property of Lessee located on or in the Demised Premises, in an amount equal to
not less than the full replacement value thereof. All proceeds of such
insurance, so long as the Lease shall remain in effect, shall be used only to
repair or replace the items so insured. Such insurance policies shall be issued
by responsible insurance companies licensed to do business in the State of
Virginia. Neither the issuance of any insurance policy required under this
Lease, nor the minimum limits specified herein with respect to Lessee's
insurance coverage, shall be deemed to limit or restrict in any way Lessee's
liability arising under or out of this Lease.

37.

        Feminine or neuter pronouns shall be substituted for those of the
masculine form, and the plural shall be substituted for the singular number, in
any place or places herein in which the context may require such substitution or
substitutions.

38.     BENEFIT AND BURDEN

        The provisions of this Lease shall be binding upon and shall inure to
the benefit of the parties hereto and each of their respective representatives,
successors and assigns (however, the foregoing shall not be deemed to permit any
assignment, sublet, encumbrance or other transfer in violation of Section 7
hereof) Lessor may freely and fully assign its interest hereunder.

                                       18
<PAGE>   19

39.     PARKING

        Lessee shall have the right, subject to Lessor's regulations and
restrictions with respect thereof, to park four (4) automobiles (3.65
automobiles for each initial 1000 square feet of space leased, rounded to the
closest whole number) in the on-site garage and surface parking lot adjacent to
the Building on an unreserved, non-exclusive basis. Lessor will issue Lessee
four (4) plastic parking passes to be placed, facing out, on the rear view
mirror of Lessee's vehicles. Vehicles (other than vehicles in bona fide visitor
parking) without Lessor-provided parking passes may be subject to towing,
booting or parking charge without prior notice at the sole risk and expense of
the vehicle owner, in Lessor's sole discretion. During the Initial Term, the
foregoing parking rights shall be free of charge and without cost to Lessee.
During the Renewal Term (if any), Lessee shall pay the Building standard charge
for such parking. Additional parking will be offered, as available, at the
Building standard charge in effect from time to time (currently $60.00 per
permit per month).

40.     MISCELLANEOUS

               (a) Recording. Neither this Lease nor any memorandum nor short
form hereof shall be recorded in the land or other records of the Commonwealth
of Virginia or Fairfax County, Virginia.

               (b) Survival of Obligations. If Lessee has failed to fulfill its
obligations under this Lease such obligations and Lessor's rights in respect
thereof shall remain in full force and effect notwithstanding the expiration of
the Term.

               (c) Headings. The captions, section numbers and index appearing
in this Lease are inserted only as a matter of convenience and reference, and in
no way shall be held to explain, modify, amplify, define, limit, construe, or
describe the scope of intent of such sections of this Lease nor in any way add
to the interpretation, construction or meaning of any provision or otherwise
affect this Lease.

               (d) Severability. If any covenant or agreement of this Lease or
the application thereof to any person or circumstance shall be held to be
invalid or unenforceable, then and in each such event the remainder of this
Lease, or the application of such covenant or agreement to any other person or
any other circumstance, as the case may be, shall not be thereby effected, and
each covenant and agreement of this Lease shall remain valid and enforceable to
the fullest extent permitted by law.

               (e)    Corporate or Partnership Authority:

                      (i)    If Lessee executes this Lease as a corporation,
each of the persons executing this Lease on behalf of Lessee hereby covenants
and warrants: (1) that Lessee is a duly authorized and existing corporation,
qualified to do business in the Commonwealth of Virginia, with full right and
authority to enter into this Lease; (2) each of the persons executing this Lease
on behalf of Lessee possesses actual authority to do so; and (3) this Lease
constitutes a valid and legally binding obligation on Lessee, enforceable
according to the terms hereof.

                      (ii) If Lessee executes this Lease as a partnership, each
of the persons executing this Lease on behalf of Lessee hereby covenants and
warrants: (1) that Lessee is a duly authorized and existing partnership,
qualified to do business in the Commonwealth of Virginia, with full right and
authority to enter into this Lease; (2) each of the persons executing this Lease
on behalf of Lessee possesses actual authority to do so; and (3) this Lease
constitutes a valid and legally binding obligation on Lessee, enforceable
according to the terms hereof.

               (f) Lessor's Liability. Notwithstanding any provision hereof to
the contrary, Lessee shall look solely to the estate and property of Lessor in
and to the Building (or the proceeds received by Lessor on a sale of such estate
and property but not the proceeds of any financing or refinancing thereof) in
the event of any claim or judgment against Lessor arising out of or in
connection with this Lease, the relationship of landlord and tenant or Lessee's
use of the Demised Premises, and Lessee agrees that the liability of Lessor
arising out of or in connection with this Lease, the relationship of landlord
and tenant or Lessee's use of the Demised Premises,


                                       19
<PAGE>   20

shall be limited to such estate and property of Lessor (or sale proceeds). No
other properties or assets of Lessor shall be subject to levy, execution or
other enforcement procedures for the satisfaction of any judgment (or other
judicial process) or for the satisfaction of any other remedy of Lessee arising
out of or in connection with this Lease, the relationship of landlord and tenant
or Lessee's use of the Demised Premises, and if Lessee shall acquire a lien on
or interest in any other properties or assets by judgment or otherwise, Lessee
shall promptly release such lien on or interest in such other properties and
assets by executing, acknowledging and delivering to Lessor an instrument to
that effect prepared by Lessor's attorneys. It is agreed that neither Lessor nor
any of its officers, directors or employees shall ever be personally liable for
any judgment against Lessor or any duty or liability of Lessor under this Lease.
Lessor shall have no liability to Lessee for failure to perform Lessor's
obligations hereunder where such failure(s) is due to causes beyond Lessor's
control, including without limitation acts of God, war, civil commotion,
strikes, and embargoes; nor shall any such failure entitle Lessee to any
abatement or reduction in Rent, except as may be expressly provided herein, or
any claim of actual or constructive eviction. Lessee shall not be entitled to
any compensation or reduction in Rent by reason of inconvenience or loss arising
from Lessor's entry onto the Demised Premises as authorized hereunder, nor by
reason of any repairs to the Demised Premises or the Building.

               (g) Governing Law. This Lease shall be governed by the laws of
the Commonwealth of Virginia, without regard to the conflict of laws principles
thereof.

               (h) Effective Date. For all purposes hereof, the "Effective Date"
of this Lease shall be the date upon which this Lease shall have been executed
by both parties and physically delivered by Lessor to Lessee or its attorney.
Prior to the Effective Date, neither this Lease nor anything hereunder contained
shall be legally binding on either Lessor or Lessee, and the submission of this
Lease by Lessor to Lessee prior to such Effective Date for examination or
consideration by Lessee or discussion between Lessor and Lessee shall not
constitute a reservation of or option for the Demised Premises or create any
legal obligation or liability whatsoever on Lessor.

41.     WAIVER OF SUBROGATION

        Notwithstanding any language to the contrary in this Lease, Lessee shall
not be responsible for damage to the Lessor's property caused by Lessee to the
extent the damage is covered by the Lessor's all risk property insurance policy.
Lessor agrees to maintain such a policy during the Lease Term and Lessor shall
obtain a waiver of subrogation under the policy in favor of the Lessee. Lessee
shall require its insurer(s) to include in all of Lessee's insurance policies
which could give rise to a claim against Lessor an endorsement whereby the
insurer(s) shall waive any rights of subrogation against Lessor. Lessee hereby
releases Lessor and its partners, officers, directors, agents and employees from
any and all liability and responsibility to Lessee or any person claiming by,
through or under Lessee, by way of subrogation or otherwise, for any injury,
loss or damage to Lessee's property covered by a valid and collectible fire
insurance policy with extended coverage endorsement. Lessee agrees to look to
its own fire and hazard insurance policies in the event of damage to Lessee's
personal property. The waivers of subrogation shall be made in writing and
delivered to the respective parties.

42.     CONTINGENCY

        This Lease shall be of no force or effect unless and until Lessor and
Solutions by Design, Inc. ("Existing Tenant") shall execute and deliver
documentation acceptable to Lessor (in Lessor's sole discretion) pursuant to
which Existing Tenant shall release all right of possession to the Demised
Premises effective on or before the Commencement Date.

43.     RENEWAL

               (a) Provided Lessee is not in default, Lessee shall have the
subordinate option, upon the terms and conditions set forth herein, to extend
the Lease Term for one (1) additional five (5) year period (herein referred to
as the "Renewal Term") Lessee may exercise the renewal option only upon binding
written notice delivered to Lessor not later than nine (9) months prior to the
expiration of the Initial Term. In the event Lessee does not timely exercise its
option for the Renewal Term, Lessee's rights under this Section 43 shall lapse.
Lessee's notice to renew 

                                       20
<PAGE>   21

shall, at Lessor's option, be deemed ineffective if Lessee is in default on the
date the notice is given or is in default on the date the Renewal Term is to
commence. The Renewal Term, if properly exercised, shall extend the Lease Term
accordingly, and shall be on all of the same terms and conditions as the Initial
Term, except that the Monthly Base Rent shall be as determined pursuant to
sub-paragraph (b), and there shall be no further Renewal Terms after the first
(1st) Renewal Term.

               (b) The Monthly Base Rent payable by Lessee during the Renewal
Term shall be one hundred percent (100%) of the prevailing market rental rate
for comparable first-class office space in first-class buildings in the Tysons
Corner area, but in no event less than the then-escalated Monthly Base Rent in
effect immediately prior to the commencement of the Renewal Term. The Monthly
Base Rent payable during the Renewal Term shall be increased annually, on each
anniversary date of the commencement of the Renewal Term, in accordance with
Section SD. Promptly following delivery of Lessee's notice of the exercise of
the renewal option, Lessor and Lessee shall meet and negotiate in good faith
toward agreement on the prevailing market rental rate for Demised Premises. In
the event that Lessor and Lessee are unable to agree in good faith on the
then-prevailing market rental rate as above described within thirty (30) days
after the Lessee gives a valid notice of the exercise of its option for the
Renewal Term, Lessee's option for the Renewal Term and any purported exercise
thereof shall be null and void and this Section 43 shall be of no further force
or effect.

               (c) Notwithstanding the foregoing provisions of this Section 43,
Lessee hereby acknowledges that Lessee's option to extend this Lease for the
Renewal Term is expressly subordinate and subject to all expansion options for
space on the third (3rd) floor of the Building which are in existence as of the
Commencement Date. In the event any tenant shall exercise its expansion option
with respect to space including the Demised Premises, this Section 43, and any
notice purporting to exercise the option to extend this Lease for the Renewal
Term, shall be deemed null and void and of no force or effect.

        This Lease, together with Exhibits A, B, B-l, C, D and E attached hereto
and made a part hereof, contains and embodies the entire agreement of the
parties hereto, and no representations, inducements, or agreements, oral or
otherwise between the parties not contained and embodied in said Lease and
Exhibits, shall be of any force or effect, and that same may not be modified,
changed or terminated in whole or in part in any manner other than by an
agreement in writing duly signed by all parties hereto.

        IN WITNESS WHEREOF, each of the parties hereto, respectively, has caused
these presents to be executed and attested by their duly authorized officers and
their seals affixed.

determined by Lessor from the respective valuations assigned in the assessor's
work sheets or such other information as may be reasonably available Lessor's
reasonable determination thereof, in good faith, shall be conclusive.

        10.5 PERSONAL PROPERTY TAXES.

               (a) Lessee shall pay prior to delinquency all taxes assessed
against and levied upon trade fixtures, furnishings, equipment and all other
personal property of Lessee contained in the Premises or elsewhere. When
possible, Lessee shall cause said trade fixtures, furnishings, equipment and all
other personal property to be assessed and billed separately from the real
property of Lessor.

               (b) If any of Lessee's said personal property shall be assessed
with Lessor's real property, Lessee shall pay to Lessor the taxes attributable
to Lessee within ten (10) days after receipt of a written statement setting
forth the taxes applicable to Lessee's property.

11.            UTILITIES. Lessee shall pay for all water, gas, heat, light,
power, telephone and other utilities and services supplied to the Premises,
together with any taxes thereon if any such services are not separately metered

reasonable proportion to be determined by Lessor of all charges jointly metered
with other premises in the Building.

12.     ASSIGNMENT AND SUBLETTING.

        12.1 LESSOR'S CONSENT REQUIRED. Lessee shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in the Lease or in the Premises,
without Lessor's prior written consent, which Lessor shall not reasonably
withhold. Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer mortgage encumbrance or
subletting without such consent shall be void, and shall constitute a breach of
this Lease without the need for notice to Lessee under paragraph 13.1.

        12.2 LESSEE AFFILIATE. Notwithstanding the provisions of paragraph 12.1
hereof, Lessee may assign or sublet the Premises, or any portion hereof, without
Lessor's consent to any corporation which controls, is controlled by or is under
common control with Lessee, or to any corporation resulting from the merger or
consolidation with Lessee, or to any person or entity which acquires all the
assets of Lessee as a going concern of the business that is being conducted on
the Premises, all of which are referred to as "Lessee Affiliate," provided that
before such assignment shall be effective said assignee shall assume, in full,
the obligations of Lessee under this Lease. Any such assignment shall not in any
way, affect or limit the liability of Lessee under the terms of this lease even
if after such assignment or subletting the terms of this Lease are materially
changed or altered without the consent of Lessee, the consent of whom shall not
be necessary.

        12.3 TERMS AND CONDITIONS OF ASSIGNMENT. Regardless of Lessor's consent,
no assignment shall release Lessee of Lessee's obligations hereunder or after
the primary liability of Lessee to pay the Base Rent and Lessee's Share of
Operating Expenses, and to perform all other obligations to be performed by
lessee hereunder. Lessor may accept rent from any person other than Lessee
pending approval or disapproval of such assignment. Neither a delay in the
approval or disapproval of such assignment nor the acceptance of rent shall
constitute a waiver or estoppel of Lessor's right to exercise its remedies for
the breach of any of the terms or conditions of this paragraph 12 or this Lease.
Consent to one assignment shall not be deemed consent to any subsequent
assignment. In the event of default by any assignee of Lessee or any successor
of Lessee, in the performance of any of the terms hereof. Lessor may proceed
directly against Lessee without the necessity of exhausting remedies against
said assignee. Lessor may consent to subsequent assignments of this Lease or
amendments or modifications to this Lease with assignees of Lessee, without
notifying Lessee, and without obtaining its or their consent thereto and such
action shall not relieve Lessee of liability under this Lease.

        12.4 TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. Regardless of
Lessor's consent, the following terms and conditions shall apply to any
subletting by Lessee of all or any part of the Premises and shall be included in
subleases:

               (a) Lessee hereby assigns and transfers to lessor all of Lessee's
interest in all rentals and income arising from any sublease heretofore or
hereafter made by Lessee, and Lessor may collect such rent and income and apply
same toward Lessee's obligations under this Lease, provided, however, that until
a default shall occur in the performance of Lessee's obligations


                                       15


<PAGE>   16
under this Lease, Lessee may receive, collect and enjoy the rents accruing under
such sublease. Lessor shall not, by reason of this or any other assignment of
such sublease to Lessor nor by reason of the collection of the rents from a
sublessee, be deemed liable to the sublessee for any failure of Lessee to
perform and comply with any of Lessee's obligations to such sublessee under such
sublease. Lessee hereby irrevocably authorizes and directs any such sublessee,
upon receipt of a written notice from Lessor stating that a default exists in
the performance of Lessee's obligations under this Lease, to pay to Lessor the
rents due and to become due under the sublease. Lessee agrees that such
sublessee shall have the right to rely upon any such statement and request from
lessor, and that such sublessee shall pay such rents to lessor without any
obligation or right to inquire as to whether such default exists and
notwithstanding any notice from or claim from lessee to the contrary, Lessee
shall have no right or claim against such sublessee or Lessor for any such rents
so paid by said sublessee to lessor.

               (b) No sublease entered into by Lessee shall be effective unless
and until it has been approved in writing by Lessor. In entering into any
sublease, Lessee shall use only such form of sublease as is satisfactory to
Lessor, and once approved by Lessor, such sublease shall not be changed or
modified without Lessor's prior written consent. Any sublessee shall, by reason
of entering into a sublease under this Lease, be deemed, for the benefit of
Lessor, to have assumed and agreed to conform and comply with each and every
obligation herein to be performed by Lessee other than such obligations as are
contrary to or inconsistent with provisions contained in a sublease to which
Lessor has expressly consented in writing.

               (c) If Lessee's obligations under this Lease have been guaranteed
by third parties, then a sublease, and Lessor's consent thereto, shall not be
effective unless said guarantors give their written consent to such sublease and
the terms thereof.

               (d) The consent by Lessor to any subletting shall not release
Lessee from its obligations or alter the primary liability of Lessee to pay the
rent and perform and comply with all of the obligations of Lessee to be
performed under this Lease.

               (e) The consent by lessor to any subletting shall not constitute
to any subsequent subletting by Lessee or to any assignment or subletting by the
sublessee. However, Lessor may consent to subsequent sublettings and assignments
of the sublease or any amendments or modifications thereto without notifying
Lessee or anyone else liable on the Lease or sublease and without obtaining
their consent and such action shall not relieve such persons from liability.

               (f) In the event of any default under this Lease, Lessor may
proceed directly against Lessee, any guarantors or any one else responsible for
the performance of this Lease, including the sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible therefor to
Lessor, or any security held by Lessor or Lessee.

               (g) In the event Lessee shall default in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of Lessee under such sublease from the time of
the exercise of said option to the termination of such


                                       16


<PAGE>   17
sublease; provided, however, Lessor shall not be liable for any prepaid rents or
security deposit paid by such sublessee to Lessee or for any other prior
defaults of Lessee under such sublease.

               (h) Each and every consent required of Lessee under a sublease
shall also require the consent of Lessor.

               (i) No sublessee shall further assign or sublet all or any part
of the Premises without Lessor's prior written consent.

               (j) Lessor's written consent to any subletting of the Premises by
Lessee shall not constitute an acknowledgment that no default then exists under
this Lease of the obligations to be performed by Lessee nor shall such consent
be deemed a waiver of any then existing default, except as may be otherwise
stated by Lessor at the time.

               (k) With respect to any subletting to which Lessor has consented,
Lessor agrees to deliver a copy of any notice of default by Lessee to the
sublessee. Such sublessee shall have the right to cure a default of Lessee
within ten (10) days after service of said notice of default upon such
sublessee, and the sublessee shall have a right of reimbursement and offset from
and against Lessee for any such defaults cured by the sublessee.

        12.5 ATTORNEY'S FEES. In the event Lessee shall assign or sublet the
Premises or request the consent of Lessor to any assignment or subletting or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable attorneys fees incurred in connection
therewith, such attorneys fees not to exceed $350.00 for each such request.

13.     DEFAULT; REMEDIES.

        13.1 DEFAULT. The occurrence of any one or more of the following events
shall constitute a material default of this Lease by Lessee:

               (a) The vacating or abandonment of the Premises by Lessee.

               (b) The failure by Lessee to make any payment of rent or any
other payment required to be made by Lessee hereunder, as and when due, where
such failure shall continue for a period of three (3) days after written notice
thereof from Lessor to Lessee. In the event that Lessor serves Lessee with a
Notice to Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes
such Notice to Pay Rent or Quit shall also constitute the notice required by
this subparagraph.

               (c) Except as otherwise provided in this Lease, the failure by
Lessee to observe or perform any of the convenants, conditions or provision of
this Lease to be observed or performed by Lessee, other than described in
paragraph (b) above, where such failure shall continue for a period of thirty
(30) days after written notice thereof from Lessor to Lessee; provided, however,
that if the nature of Lessee's noncompliance is such that more than thirty (30)
days are reasonably required for its cure, then Lessee shall not be deemed to be
in default if


                                       17


<PAGE>   18
Lessee commenced such cure within said thirty (30) day period and thereafter
diligently prosecutes such cure to completion. To the extent permitted by law,
such thirty (30) day notice shall constitute the sole and exclusive notice
required to be given to Lessee under applicable Unlawful Detainer statutes.

               (d) (i) The making by Lessee of any general arrangement or
general assignment for the benefit of creditors; (ii) Lessee becomes a "debtor"
as defined in 11 U.S.C. Section 101 or any successor stature thereto (unless, in
the case of a petition filed against Lessee, the same is dismissed within sixty
(60) days, (iii) the appointment of a trustee or receiver to take possession of
substantially all of Lessee's assets located at the premises or of Lessee's
interest in this lease, where possession is not restored to Lessee within thirty
(30) days; or (iv) the attachment, execution or other judicial seizure of
substantially all of Lessee's assets located at the premises or of Lessee's
interest in this Lease, where such seizure is not discharged within thirty (30)
days. In the event that any provision of this paragraph 13.1(d) is contrary to
any applicable law, such provision shall be of no force or effect.

               (e) The discovery by Lessor that any financial statement given to
Lessor by Lessee, any assignee of Lessee, any subtenant of Lessee, any successor
in interest of Lessee or any guarantor of Lessee's obligation hereunder, was
materially false.

        13.2 REMEDIES. In the event of any such material default by Lessee,
Lessor may at any time thereafter, with or without notice or demand and without
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such default:

               (a) Terminate Lessee' right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor. In such
event Lessor shall be entitled to recover from Lessee all damages incurred by
Lessor by reason of Lessee's default including, but not limited to, the cost of
recovering possession of the Premises; expenses of reletting, including
necessary renovation and alteration of the premises, reasonable attorney's fees,
and any real estate commission actually paid; the worth at the time of award by
the court having jurisdiction thereof of the amount by which the unpaid rent for
the balance of the term after the time of such award exceeds the amount of such
rental loss for the same period that Lessee proves could be reasonably avoided;
that portion of the leasing commission paid by Lessor pursuant to paragraph 15
applicable to the unexpired term of this Lease.

               (b) Maintain Lessee's right to possession in which case this
lease shall continue in effect whether or not Lessee shall have vacated or
abandoned the Premises. IN such event Lessor shall be entitled to enforce all of
Lessor's rights and remedies under this Lease, including the right to recover
the rent as it becomes due hereunder.

               (c) Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located. Unpaid installments of rent and other unpaid monetary obligations of
Lessee under the terms of this Lease shall bear interest from the date due at
the maximum rate then allowable by law.


                                       18


<PAGE>   19
        13.3 DEFAULT BY LESSOR. Lessor shall not be in default unless Lessor
fails to perform obligations required of Lessor within a reasonable time, but in
no event later than thirty (30) days after written notice by Lessee to Lessor
and to the holder of any first mortgage or deed of trust covering the Premises
whose name and address shall have theretofore been furnished to lessee in
writing, specifying wherein Lessor has failed to perform such obligation,
provided, however, that if the nature of Lessor's obligation is such that more
than thirty (30) days are required for performance then Lessor shall not be in
default, if Lessor commences performance within such thirty (30) day period and
thereafter diligently prosecutes the same to completion.

        13.4 LATE CHARGES. Lessee hereby acknowledges that late payment by
Lessee to Lessor of Base Rent, Lessee's Share of Operating Expenses or other
sums due hereunder will cause Lessor to incur costs not contemplated by this
Lease, the exact amount of which will be extremely difficult to ascertain. Such
costs include, but are not limited to, processing and accounting charges, and
late charges which may be imposed on Lessor by the terms of any mortgage or
trust deed covering the Property. Accordingly, if any installment of Base Rent,
Operating Expenses, or any other sum due from Lessee shall not be received by
Lessor or Lessor's designee within ten (10) days after such amount shall be due,
then, without any requirement for notice to Lessee, Lessee shall pay to Lessor a
late charge equal to 6% of such overdue amount. The parties hereby agree that
such late charge represents a fair and reasonable estimate of the costs Lessor
will incur by reason of late payment by Lessee. Acceptance of such late charge
by Lessor shall in no event constitute a waiver of Lessee's default with respect
to such overdue amount, nor prevent Lessor from exercising any of the other
rights and remedies granted hereunder. In the event that a late charge is
payable hereunder, whether or not collected, for three (3) consecutive
installments of any of the aforesaid monetary obligations of Lessee, then Base
Rent shall automatically become due and payable quarterly in advance, rather
than monthly, notwithstanding paragraph (4) or any other provision of this Lease
to the contrary.

14.     CONDEMNATION. If the Premises or any portion thereof or the Industrial
Center are taken under the power of eminent domain, or sold under the threat of
the exercise of said power (all of which are herein called "condemnation"), this
Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever first occurs. If more than ten
percent of the floor area of the Premises, or more than twenty-five percent of
that portion of the Common Areas designated as parking for the Industrial Center
is taken by condemnation, Lessee may, at Lessee's option, to be exercised in
writing only within ten (10) days after Lessor shall have given Lessee written
notice of such taking (or in the absence of such notice, within ten (10) days
after the condemning authority shall have taken possession) terminate this Lease
as of the date the condemning authority takes such possession. If Lessee does
not terminate this Lease in accordance with the foregoing, this Lease shall
remain in full force and effect as to the portion of the premises remaining
except that the rent shall be reduced in the proportion that the floor area of
the Premises taken bears to the total floor area of the Premises. No reduction
of rent shall occur if the only area taken is that which does not have the
premises located thereon. Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of such power shall be the property of Lessor, whether such award
shall be made as compensation for diminution in value of the leasehold or for
the taking of the fee, or as severance damages, provided, however, that Lessee
shall be entitled to


                                       19


<PAGE>   20
any award for loss of or damage to Lessee's trade fixtures and removable
personal property. In the event that this Lease is not terminated by reason of
such condemnation, Lessor shall to the extent of severance damages received by
Lessor in connection with such condemnation, repair any damage to the Premises
caused by such condemnation except to the extent that Lessee has been reimbursed
therefor by the condemning authority. Lessee shall pay any amount in excess of
such severance damages required to complete such repair.

15.     BROKER'S FEE.

        (a) Upon execution of this Lease by both parties, Lessor shall pay to
None Licensed real estate broker(s) a fee as set forth in a separate agreement
between Lessor and said broker(s), or in the event there is no separate
agreement between Lessor and said broker(s), the sum of $0.00, for brokerage
services rendered by said broker(s) to Lessor in this transaction.

        (b) Lessor further agrees that if Lessee exercises any Option, as
defined in paragraph 39.1 of this Lease, which is granted to Lessee under this
Lease, or any subsequently granted option which is substantially similar to an
Option granted to Lessee under this Lease, or if Lessee acquires any rights to
the Premises or other premises described in this Lease which are substantially
similar to what Lessee would have acquired had an Option herein granted to
Lessee been exercised, or if Lessee remains in possession of the Premises after
the expiration of the terms of this Lease after having failed to exercise an
Option, or if said broker(s) are the procuring cause of any other lease or sale
entered into between the parties pertaining to the Premises and/or adjacent
property in which Lessor has an interest, then as to any of said transactions,
Lessor shall pay said broker(s) a fee in accordance with the schedule of said
broker(s) in effect at the time of execution of this Lease.

        (c) Lessor agrees to pay said fee not only on behalf of Lessor but also
on behalf of any person, corporation, association, or other entity having an
ownership interest in said real property or any part thereof, when such fee is
due hereunder. Any transferee of Lessor's interests in this Lease, whether such
transfer is by agreement or by operation of law shall be deemed to have assumed
Lessor's obligation under this paragraph 15. Said broker shall be a third party
beneficiary of the provisions of this paragraph 15.

16.     ESTOPPEL CERTIFICATE.

        (a) Each party (as "responding party") shall at any time upon not less
than ten (10) days' prior written notice from the other party ("requesting
party") execute acknowledge and deliver to the requesting party a statement in
writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying

statement within such time shall be a material default of this Lease by the

conclusive upon such party that (i) this Lease is in full force and effect,
without modification except as may be represented by the requesting party, (ii)
there are no uncured defaults in the requesting party's performance, and (iii)
if Lessor is the requesting party, not more than one month's rent has been paid

any part thereof, Lessee hereby agrees to deliver to any lender or purchaser
designated by Lessor such financial statements of Lessee as may be reasonably
required by such lender or purchaser. Such statements shall include the past
three (3) years' financial statements of lessee. All such financial statements
shall be received by Lessor and such lender or purchaser in confidence and shall

interest in a ground lease of the Industrial Center, and except as expressly
provided in paragraph 15, in the event of any transfer of such title or
interest. Lessor herein named (and in case of any subsequent transfers then the
grantor) shall be relieved from and after the date of such transfer of all
liability as respects Lessor's obligations thereafter to be performed, provided
that any funds in the hands of Lessor or the then grantor at the time of such
transfer, in which Lessee has an interest, shall be delivered to the grantee.
The obligations contained in this Lease to be performed by Lessor shall, subject
as aforesaid, be binding on Lessor's successors and assigns only during their
respective periods of ownership.

18.     SEVERABILITY. The invalidity of any provision of this Lease as
determined b a court of competent jurisdiction, shall in no way affect the
validity of any other provision hereof.

19.     INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein provided,
any amount due to lessor not paid when due shall bear interest at the maximum
rate then allowable by law from the date due. Payment of such interest shall not
excuse or cure any default by Lessee under this Lease, provided, however, that
interest shall not be payable on late charges incurred by Lessee nor on any
amounts upon which late charges are paid by Lessee.

agreements of the parties with respect to any matter mentioned herein. No prior
or contemporaneous agreement or understanding pertaining to any such matter

REGARDLESS OF LESSOR'S KNOWLEDGE OF SUCH PRECEDING BREACH AT THE TIME OF
ACCEPTANCE OF SUCH RENT.

option, shall be subordinate to any ground lease, mortgage, deed of trust, or
any other hypothecation or security now or hereafter placed upon the Industrial
Center and to any and all advances made on the security thereof and to all
renewals, modifications, consolidations, replacements and extensions thereof.
Notwithstanding such subordination, Lessee's right to quiet possession of the
Premises shall not be disturbed if Lessee is not in default and so long as
Lessee shall pay the rent and observe and perform all of the provisions of this
Lease, unless this Lease is otherwise terminated pursuant to its terms. If any
mortgagee, trustee or ground lessor shall elect to have this Lease and any
Options granted hereby prior to the lien of its mortgage, deed of trust or
ground lease, and shall give written notice thereof to Lessee, this Lease and
such Options shall be deemed prior to such mortgage, deed of trust or ground
lease, whether this Lease or such Options are dated prior or subsequent to the
date of said mortgage, deed of trust or ground lease or the date of recording
thereof.

an attornment, a subordination or to make this Lease or any Option granted
herein prior to the lien of any mortgage, deed of trust or ground lease, as the
case may be. Lessee's failure to execute such documents within ten (10) days
after written demand shall constitute a material default by Lessee hereunder
without further notice to Lessee or, at Lessor's option, Lessor shall execute
such documents on behalf of Lessee as Lessee's attorney-in-fact. Lessee does
hereby make, constitute and irrevocably appoint Lessor as Lessee's

documents in accordance with this paragraph 30(b).

31.     ATTORNEY'S FEES. If either party or the broker(s) named herein bring an
action to enforce the terms hereof or declare rights hereunder, the prevailing
party in any such action, on trial or appeal, shall be entitled to his
reasonable attorney's fees to be paid by the losing party as fixed by the court.
The provisions of this paragraph shall insure to the benefit of the broker named
herein who seeks to enforce a right hereunder.

32.     LESSOR'S ACCESS. Lessor and Lessor's agents shall have the right to
enter the Premises at reasonable times for the purpose of inspecting the same,
showing the same to prospective purchasers, lenders, or lessees, and making such
alterations, repairs, improvements or additions to the Premises or to the
building of which they are part as Lessor may deem necessary or desirable.
Lessor may at any time place on or about the Premises or the Building any
ordinary "For Sale" signs and Lessor may at any time during the last 120 days of
the term hereof place on or about the Premises any ordinary "For Lease" signs.
All activities of Lessor pursuant to the paragraph shall be without abatement of
rent, nor shall Lessor have any liability to Lessee for the same.

exercise any standard of reasonableness in determining whether to grant such
consent.

Industrial Center without Lessor's prior written consent. Under no circumstances
shall Lessee place a sign on any roof of the Industrial Center.

mutual cancellation thereof, or a termination by Lessor, shall not work a
merger, and shall, at the option of Lessor, terminate all or any existing
subtenancies or may, at the option of Lessor, operate as an assignment to Lessor
of any or all of such subtenancies.

36.     CONSENTS. Except for paragraph 33 hereof, wherever in this Lease the
consent of one party is required to an act of the other party such consent shall
not be unreasonably withheld or delayed.

provisions of this Lease. The individuals executing this Lease on behalf of
Lessor represent and warrant to Lessee that they are fully authorized and
legally capable of executing this Lease on behalf of Lessor and that such

while occupying the Premises who does so without the intent of thereafter
assigning this Lease or subletting the Premises or


                                       24


<PAGE>   25
any portion thereof, and may not be exercised or be assigned, voluntarily or
involuntarily, by or to any person or entity other than Lessee, provided,
however, that an Option may be exercised by or assigned to any Lessee Affiliate
as defined in paragraph 12.2 of this Lease. the Options, of any, herein granted
to Lessee are not assignable separate and apart from this Lease, nor may any
Option be separated from this Lease in any manner, either by reservation or
otherwise.

        39.3. MULTIPLE OPTIONS. In the event that Lessee has any multiple
options to extend or renew this Lease a later option cannot be exercised unless
the prior option to extend or renew this Lease has been so exercised.

        39.4. EFFECT OF DEFAULT ON OPTIONS.

               (a) Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary, (i) during
the time commencing from the date Lessor gives to Lessee a notice of default
pursuant to paragraph 13.1(b) or 13.1(c) and continuing until the noncompliance
alleged in said notice of default is cured, or (ii) during the period of time
commencing on the date after a monetary obligation to Lessor is due from Lessee
and unpaid (without any necessity for notice thereof to Lessee) and continuing
until the obligation is paid, or (iii) at any time after an event of default
described in paragraphs 13.1(a), 13.1(d), or 13.1(e) without any necessity of
Lessor to give notice of such default to Lessee) or (iv) in the event that
Lessor has given to Lessee three or more notices of default under paragraph
13.1(b), or paragraph 13.1(c), whether or not the defaults are cured, during the
12 month period of time immediately prior to the time that Lessee attempts to
exercise the Subject Option.

               (b) The period of time within which an Option may be exercised
shall not be extended or enlarged by reason of Lessee's inability to exercise an
Option because of the provisions of paragraph 39.4(a).

               (c) All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due and
timely exercise of the Option, if, after such exercise and during the term of
this Lease, (I) Lessee fails to pay to Lessor a monetary obligation of Lessee
for a period of thirty (30) days after such obligation becomes due (without any
necessity of Lessor to give notice thereof to Lessee) or (ii) Lessee fails to
commence to cure a default specified in paragraph 13.1(c) within thirty (30)
days after the date that Lessor gives notice to Lessee of such default and/or
Lessee fails thereafter to diligently prosecute said cure to completion, or
(iii) Lessee commits a default described in paragraph 13.1(a), 13.1(d) or
13.1(e) (without any necessity of Lessor to give notice of such default to
Lessee), or (iv) Lessor gives to Lessee three or more notices of default under
paragraph 13.1(b), or paragraph 13.1(c), whether or not the defaults are cured.

40.            SECURITY MEASURES. Lessee hereby acknowledges that Lessor shall
have no obligation whatsoever to provide guard service or other security
measures for the benefit of the Premises or the Industrial Center. Lessee
assumes all responsibility for the protection of Lessee, its agents, and
invitees and the property of Lessee and of Lessee's agents and invitees from
acts of third parties. Nothing herein contained shall prevent Lessor, at
Lessor's sole option, from providing


                                       25


<PAGE>   26
security protection for the Industrial Center or any part thereof, in which
event the cost thereof shall be included within the definition of Operating
Expenses, as set forth in paragraph 4.2(b).

41.            EASEMENTS. Lessor reserves to itself the right, from time to
time, to grant such easements, rights and dedications that Lessor deems
necessary or desirable, and to cause the recordation of Parcel Maps and
restrictions, so long as such easements, rights, dedications, Maps and
restrictions do not unreasonably interfere with the use of the Premises by
Lessee, Lessee shall sign any of the aforementioned documents upon request of
Lessor and failure to do so shall constitute a material default of this Lease by
Lessee without the need for further notice to Lessee.

42.            PERFORMANCE UNDER PROTEST. If at any time a dispute shall arise
as to any amount or sum of money to be paid by one party to the other under the
provisions hereof, the party against whom the obligation to pay the money is
asserted shall have the right to m made payment "under protest" and such payment
shall not be regarded as a voluntary payment, and there shall survive the right
on the part of said party to institute suit for recovery of such sum if it shall
be adjudged that there was no legal obligation on the part of said party to pay
such sum or any part thereof, said party shall be entitled to recover such sum
or so much thereof as it was not legally required to pay under the provisions of
this Lease.

43.            AUTHORITY. If Lessee is a corporation, trust, or general or
limited partnership, each individual executing this Lease on behalf of such
entity represents and warrants that he or she is duly authorized to execute and
deliver this Lease on behalf of said entity. If Lessee is a corporation, trust
or partnership, Lessee shall, within thirty (30) days after execution of this
Lease, deliver to Lessor evidence of such authority satisfactory to Lessor.

Lease and the typewritten or handwritten provisions, if any, shall be controlled
by the typewritten or handwritten provisions.

45.            OFFER. Preparation of this Lease by Lessor or Lessor's agent and

                       QUALIFIED RETIREMENT PLAN AND TRUST
                   DEFINED CONTRIBUTION BASIC PLAN DOCUMENT 01

================================================================================

                                   SECTION ONE
                                   DEFINITIONS

        The following words and phrases when used in the Plan with initial
        capital letters shall, for the purpose of this Plan, have the meanings
        set forth below unless the context indicates that other meanings are
        intended:

1.01    ADOPTION AGREEMENT

        Means the document executed by the Employer through which it adopts the
        Plan and Trust and thereby agrees to be bound by all terms and
        conditions of the Plan and Trust.

1.02    BASIC PLAN DOCUMENT

        Means this regional prototype Plan and Trust document.

1.03    BREAK IN ELIGIBILITY SERVICE

        Means a 12 consecutive month period which coincides with an Eligibility
        Computation Period during which an Employee fails to complete more than
        500 Hours of Service (or such lesser number of Hours of Service
        specified in the Adoption Agreement for this purpose).

1.04    BREAK IN VESTING SERVICE

        Means a Plan Year during which an Employee fails to complete more than
        500 Hours of Service (or such lesser number of Hours of Service
        specified in the Adoption Agreement for this purpose).

1.05    CODE

        Means the Internal Revenue Code of 1986 as amended from time-to-time.

1.06    COMPENSATION

        For Plan Years beginning on or after January 1, 1989, the following
        definition of Compensation shall apply:

        Unless another definition of Compensation is selected in the Adoption
        Agreement, Compensation will mean all of each Participant's W-2
        earnings. For any Self-Employed Individual covered under the Plan,
        Compensation will mean Earned Income. 




<PAGE>   7

        Compensation shall include only that Compensation which is actually paid
        to the Participant during the applicable period. Except as provided
        elsewhere in this Plan, the applicable period shall be the Plan Year
        unless the Employer has selected another period in the Adoption
        Agreement.

        Unless otherwise indicated in the Adoption Agreement, Compensation shall
        include any amount which is contributed by the Employer pursuant to a
        salary reduction agreement and which is not includible in the gross
        income of the Employee under Sections 125, 402(a)(8), 402(h) or 403(b))
        of the Code.

        The annual Compensation of each Participant taken into account under the
        Plan for any year shall not exceed $200,000, as adjusted by the
        Secretary at the same time and in the same manner as under Section
        415(d) of the Code. In determining the Compensation of a Participant for
        purposes of this limitation, the rules of Section 414(q)(6) of the Code
        shall apply, except in applying such rules, the term "family" shall
        include only the spouse of the Participant and any lineal descendants of
        the Participant who have not attained age 19 before the dose of the
        year.

        If, as a result of the application of such rules the adjusted $200,000
        limitation is exceeded, then (except for purposes of determining the
        portion of Compensation up to the integration level if this Plan
        provides for permitted disparity), the limitation shall be prorated
        among the affected individuals in proportion to each such individual's
        Compensation as determined under this Section prior to the application
        of this limitation.

        Unless otherwise indicated in the Adoption Agreement, where an Employee
        enters the Plan (and thus becomes a Participant) on an Entry Date other
        than the first Entry Date in a Plan Year, his Compensation will not
        include any earnings paid to him before the Employee enters the Plan.

        However, if this Plan is a 401(k) plan as indicated in the Adoption
        Agreement, a Participant's Compensation for purposes of the Actual
        Deferral Percentage (ADP) and Actual Contribution Percentage (ACP) tests
        described in Sections 11.401 and 11.402, respectively, shall be his
        earnings for the entire Plan Year. (Pursuant to Section 5.03 of Revenue
        Procedure 89~5, the preceding sentence shall not apply for Plan Years
        beginning before the later of January 1, 1992 or the date that is 60
        days after the publication by the Secretary of final regulations under
        Sections 401(k) and 401(m) of the Code.)

        Where this Plan is being adopted as an amendment and restatement to
        bring a Prior Plan into compliance with the Tax Reform Act of 1986, such
        Prior Plan's definition of Compensation shall apply for Plan Years
        beginning before January 1, 1989.

        In addition to other applicable limitations set forth in the Plan, and
        notwithstanding any other provision of the Plan to the contrary, for
        Plan Years beginning on or after January 1, 1994, the annual
        Compensation of each Employee taken into account under the Plan shall
        not exceed the OBRA '93 annual



                                       2
<PAGE>   8

        Compensation limit. The OBRA '93 annual Compensation limit is $150,000,
        as adjusted by the Commissioner for increases in the cost of living in
        accordance with Section 401(a)(17)(B) of the Internal Revenue Code. The
        cost-of-living adjustment in effect for a calendar year applies to any
        period, not exceeding 12 months, over which Compensation is determined
        (determination period) beginning in such calendar year. If a
        determination period consists of fewer than 12 months, the OBRA '93
        annual Compensation limit will be multiplied by a fraction, the
        numerator of which is the number of months in the determination period,
        and the denominator of which is 12.

        For Plan Years beginning on or after January 1, 1994, any reference in
        this Plan to the limitation under Section 401(a)(17) of the Code shall
        mean the OBRA '93 annual Compensation limit set forth in this provision.

        If Compensation for any prior determination period is taken into account
        in determining an Employee's benefits accruing in the current Plan Year,
        the Compensation for that prior determination period is subject to the
        OBRA '93 annual Compensation limit in effect for that prior
        determination period. For this purpose, for determination periods
        beginning before the first day of the first Plan Year beginning on or
        after January 1, 1994, the OBRA '93 annual Compensation limit is
        $150,000.

1.07    CUSTODIAN

        Means an entity specified in the Adoption Agreement as Custodian or any
        duly appointed successor as provided in Section 5.09.

1.08    DISABILITY

        Means the inability to engage in any substantial, gainful activity by
        reason of any medically determinable physical or mental impairment that
        can be expected to result in death or which has lasted or can be
        expected to last for a continuous period of not less than 12 months. The
        permanence and degree of such impairment shall be supported by medical
        evidence.

1.09    EARNED INCOME

        Means the net earnings from self-employment in the trade or business
        with respect to which the Plan is established, for which personal
        services of the individual are a material income-producing factor. Net
        earnings will be determined without regard to items not included in
        gross income and the deductions allocable to such items. Net earnings
        are reduced by contributions by the Employer to a qualified plan to the
        extent deductible under Section 404 of the Code.

        Net earnings shall be determined with regard to the deduction allowed to
        the Employer by Section 164(f) of the Code for taxable years beginning
        after December 31, 1989.


                                       3
<PAGE>   9

1.10    EFFECTIVE DATE

        Means the date the Plan becomes effective as indicated in the Adoption
        Agreement. However, where a separate date is stated in the Plan as of
        which a particular Plan provision becomes effective, such date will
        control with respect to that provision.

1.11    ELIGIBILITY COMPUTATION PERIOD

        An Employee's initial Eligibility Computation Period shall be the 12
        consecutive month period commencing with the date such Employee first
        performs an Hour of Service (employment commencement date). His
        subsequent Eligibility Computation Periods shall be the 12 consecutive
        month periods commencing on the anniversaries of his employment
        commencement date; provided, however, if pursuant to the Adoption
        Agreement, an Employee is required to complete one or less Years of
        Eligibility Service to become a Participant, then his subsequent
        Eligibility Computation Periods shall be the Plan Years commencing with
        the Plan Year beginning during his initial Eligibility Computation
        Period.

1.12    EMPLOYEE

        Means any person employed by the Employer maintaining the Plan or of any
        other employer required to be aggregated with such Employer under
        Sections 414(b), (c), (m) or (o) of the Code.

        The term Employee shall also include any Leased Employee deemed to be an
        Employee of any Employer described in the previous paragraph as provided
        in Sections 414(n) or (o) of the Code.

1.13    EMPLOYER

        named in the Adoption Agreement and any successor who by merger,
        consolidation, purchase or otherwise assumes the obligations of the
        Plan. A partnership is considered to be the Employer of each of the
        partners and a sole-proprietorship is considered to be the Employer of a
        sole proprietor.

1.14    EMPLOYER CONTRIBUTION

        Means the amount contributed by the Employer each year as determined
        under this Plan.

1.15    ENTRY DATES

        Means the first day of the Plan Year and the first day of the seventh
        month of the Plan Year, unless the Employer has specified more frequent
        dates in the Adoption Agreement.

        Participants' exclusive benefit.

1.19    HIGHLY COMPENSATED EMPLOYEE

        The term Highly Compensated Employee includes highly compensated active
        employees and highly compensated former employees.

        A highly compensated active employee includes any Employee who performs
        service for the Employer during the determination year and who, during
        the look-back year (a) received Compensation from the Employer in excess
        of $75,000 (as adjusted pursuant to Section 415(d) of the Code); (0)
        received Compensation from the Employer in excess of $50,000 (as
        adjusted pursuant to Section 415(d) of the Code) and was a member of the
        top-paid group for such year; or (c) was an officer of the Employer and
        received Compensation during such year that is greater than 50% of the
        dollar limitation in effect under Section 415(0)~)(A) of the Code. The
        term Highly Compensated Employee also includes: (a) Employees who are
        both described in the preceding sentence if the term "determination
        year" is substituted for the term "look-back year" and the Employee is
        one of the 100 Employees who received the most Compensation from the
        Employer during the determination year; and (b) Employees who are 5%
        owners at any time during the look-back year or determination year.

        If no officer has satisfied the Compensation requirement of (c) above
        during either a determination year or look-back year, the highest paid
        officer for such year shall be treated as a Highly Compensated Employee.

        For this purpose, the determination year shall be the Plan Year. The
        look-back year shall be the 12 month period immediately preceding the
        determination year.

        A highly compensated former employee includes any Employee who separated
        from service (or was deemed to have separated) prior to the
        determination year, performs no service for the Employer during the
        determination year, and was a highly compensated active employee for
        either the separation year or any determination year ending on or after
        the Employee's 55th birthday.

                                       5
<PAGE>   11

        If an Employee is, during a determination year or look-back year, a
        family member of either a 5% owner who is an active or former Employee
        or a Highly Compensated Employee who is one of the 10 most Highly
        Compensated Employees ranked on the basis of Compensation paid by the
        Employer during such year, then the family member and the 5% owner or
        top 10 Highly Compensated Employee shall be aggregated. In such case,
        the family member and 5% owner or top 10 Highly Compensated Employee
        shall be treated as a single Employee receiving Compensation and Plan
        contributions or benefits equal to the sum of such Compensation and
        contributions or benefits of the family member and 5% owner or top 10
        Highly Compensated Employee. For purposes of this Section, family member
        includes the spouse, lineal ascend ants and descendants of the Employee
        or former Employee and the spouses of such lineal ascendants and
        descendants.

        The determination of who is a Highly Compensated Employee, including the
        determinations of the number and identity of Employees in the top-paid
        group, the top 100 Employees, the number of Employees treated as
        officers and the Compensation that is considered, will be made in
        accordance with Section 414(q) of the Code and the regulations
        thereunder.

1.20    HOURS OF SERVICE - MEANS

        A. Each hour for which an Employee is paid, or entitled to payment, for
           the performance of duties for the Employer. These hours will be
           credited to the Employee for the computation period in which the
           duties are performed; and

        B. Each hour for which an Employee is paid, or entitled to payment, by
           the Employer on account of a period of time during which no duties
           are performed (irrespective of whether the employment relationship
           has terminated) due to vacation, holiday, illness, incapacity
           (including disability), layoff, jury duty, military duty or leave of
           absence. No more than 501 Hours of Service will be credited under
           this paragraph for any single continuous period (whether or not such
           period occurs in a single computation period). Hours under this
           paragraph shall be calculated and credited pursuant to Section
           2530.200b-2 of the Department of Labor Regulations which is
           incorporated herein by this reference; and

        C. Each hour for which back pay, irrespective of mitigation of damages,
           is either awarded or agreed to by the Employer. The same Hours of
           Service will not be credited both under paragraph (A) or paragraph
           (B), as the case may be, and under this paragraph (C). These hours
           will be credited to the Employee for the computation period or
           periods to which the award or agreement pertains rather than the
           computation period in which the award, agreement, or payment is made.

        D. Solely for purposes of determining whether a Break in Eligibility
           Service or a Break in Vesting Service has occurred in a computation
           period (the computation period for purposes of determining whether a
           Break in Vesting Service has occurred is the Plan Year), an
           individual who is absent from work for maternity or paternity reasons
           shall 



                                       6
<PAGE>   12

            receive credit for the Hours of Service which would otherwise have
            been credited to such individual but for such absence, or in any
            case in which such hours cannot be determined, 8 Hours of Service
            per day of such absence. For purposes of this paragraph, an absence
            from work for maternity or paternity reasons means an absence (1) by
            reason of the pregnancy of the individual, (2) by reason of a birth
            of a child of the individual, (3) by reason of the placement of a
            child with the individual in connection with the adoption of such
            child by such individual, or (4) for purposes of caring for such
            child for a period beginning immediately following such birth or
            placement. The Hours of Service credited under this paragraph shall

           Date if he has met the eligibility requirements of Section 2.01 as of
           such date. After the Effective Date, each Employee shall become a
           Participant on the first Entry Date following the date the Employee
           satisfies the eligibility requirements of Section 2.01.

        C. The Plan Administrator shall notify each Employee who becomes
           eligible to be a Participant under this Plan and shall furnish him

        If an Employee who had been a Participant becomes ineligible to
        participate because he is no longer a member of an eligible class of
        Employees, but has not incurred a Break in Eligibility Service, such
        Employee shall participate immediately upon his return to an eligible
        class of Employees. If such Employee incurs a Break in Eligibility
        Service, his eligibility to participate shall be determined by Section
        2.04.

        An Employee who is not a member of the eligible class of Employees will
        become a Participant immediately upon becoming a member of the eligible
        class provided such Employee has satisfied the age and Years of
        Eligibility Service requirements. If such Employee has not satisfied the
        age and Years of Eligibility Service requirements as of the date he
        becomes a member of the eligible class, he shall become a Participant on

           requirements, such Employee's Years of Eligibility Service before
           such Break in Eligibility Service will not be taken into account.

        B. NONVESTED PARTICIPANTS - In the case of a Participant who does not
           have a Vested interest in his Individual Account derived from
           Employer Contributions, Years of Eligibility Service before a period
           of consecutive Breaks in Eligibility Service will not be taken into
           account for eligibility purposes if the number of consecutive Breaks
           in Eligibility Service in such period equals or exceeds the greater
           of 5 or the aggregate number of Years of Eligibility Service before
           such break. Such aggregate number of Years of Eligibility Service
           will not include any Years of Eligibility Service disregarded under
           the preceding sentence by reason of prior breaks.

           If a Participant's Years of Eligibility Service are disregarded
           pursuant to the preceding paragraph, such Participant will be treated
           as a new Employee for eligibility purposes. If a Participant's Years
           of Eligibility Service may not be disregarded pursuant to the
           preceding paragraph, such Participant shall continue to participate
           in the Plan, or, if terminated, shall participate immediately upon
           reemployment.

        C. VESTED PARTICIPANTS - A Participant who has sustained a Break in
           Eligibility Service and who had a Vested interest in all or a portion
           of his Individual Account derived from Employer Contributions shall
           continue to participate in the Plan, or, if terminated, shall
           participate immediately upon reemployment.

               delegate) of the Key Employee's Compensation, allocated on behalf
               of any Key Employee for that year. The minimum allocation is
               determined will,, regard to any Social Security contribution.
               This minimum allocation shall be made even though under other
               Plan provisions, the Participant would not otherwise be entitled
               to receive an allocation, or would have received a lesser
               allocation for the year because of (a) the Participant's failure
               to complete 1,000 Hours of Service (or any equivalent provided in
               the Plan), or (b) the Participant's failure to make mandatory
               Employee Contributions to the Plan, or (c) Compensation less than
               a stated amount.

          2.   For purposes of computing the minimum allocation, Compensation
               shall mean Compensation as defined in Section 1.06 of the Plan.

          3.   The provision in (1) above shall not apply to any Participant who
               was not employed by the Employer on the last day of the Plan
               Year.

          4.   The provision in (1) above shall not apply to any Participant to
               the extent the Participant is covered under any other plan or
               plans of the Employer and the Employer has provided in the
               Adoption Agreement that the minimum allocation or benefit
               requirement applicable to Top-Heavy Plans will be met in the
               other plan or plans.

          5.   The minimum allocation required under this Section 3.01(E) and
               Section 3.01(F)(1) (to the extent required to be nonforfeitable
               under Code Section 416(b)) may not be forfeited under Code
               Section 411(a)(3)(B) or 411(a)(3)(D).

        F. SPECIAL REQUIREMENTS FOR PAIRED PLANS - The Employer maintains paired
           plans if the Employer has adopted both a standardized profit sharing
           plan and a standardized money purchase pension plan using this Basic
           Plan Document.

          1.   Minimum Allocation - The mandatory minimum allocation provision
               of Section 3.01(E) shall not apply to any Participant if the
               Employer maintains paired plans. Rather, the following rules will
               apply when the plans are Top-Heavy. For each Plan Year, the
               Employer will provide the minimum contribution described in
               Section 3.01(E) for each non-Key Employee who is entitled to a



                                       15
<PAGE>   21

               minimum contribution. Such minimum contribution will only be made
               to one of the Plans. If an Employee is a Participant in only one
               of the Plans, the minimum contribution shall be made to that
               Plan. If the Employee is a Participant in both Plans, the minimum
               contribution shall be made to the money purchase plan.

           2.  Only One Plan Can Be Integrated - If the Employer maintains
               paired plans, only one of the Plans may provide for the disparity
               in contributions which is permitted under Section 401(1) of the
               Code. In the event that both Adoption Agreements provide for such
               integration, only the money purchase pension plan shall be deemed
               to be integrated.

        G. RETURN OF THE EMPLOYER CONTRIBUTION TO THE EMPLOYER UNDER SPECIAL
           CIRCUMSTANCES Any contribution made by the Employer because of a
           mistake of fact must be returned to the Employer within one year of
           the contribution.

           In the event that the Commissioner of Internal Revenue determines
           that the Plan is not initially qualified under the Code, any
           contributions made incident to that initial qualification by the
           Employer must be returned to the Employer within one year after the
           date the initial qualification is denied, but only if the application
           for qualification is made by the time prescribed by law for filing
           the Employer's return for the taxable year in which the Plan is
           adopted, or such later date as the Secretary of the Treasury may
           prescribe.

           In the event that a contribution made by the Employer under this Plan
           is conditioned on deductibility and is not deductible under Code
           Section 404, the contribution, to the extent of the amount
           disallowed, must be returned to the Employer within one year after
           the deduction is disallowed.

        H. OMISSION OF PARTICIPANT

           1.  If the Plan is a money purchase plan or a target benefit plan
               and, if in any Plan Year, any Employee who should be included as
               a Participant is erroneously omitted and discovery of such
               omission is not made until after a contribution by the Employer
               for the year has been made and allocated, the Employer shall make
               a subsequent contribution with respect to the omitted Employee in
               the amount which the Employer would have contributed with respect
               to that Employee had he not been omitted.

           2.  If the Plan is a profit sharing plan, and if in any Plan Year,
               any Employee who should be included as a Participant is
               erroneously omitted and discovery of such omission is not made
               until after the Employer Contribution has been made and
               allocated, then the Plan Administrator must re-do the allocation
               (if a correction can be made) and inform the Employee.
               Alternatively, the Employer may choose to contribute for the
               omitted Employee the amount which the Employer would have
               contributed for him.

3.02    EMPLOYEE CONTRIBUTIONS

        This Plan will not accept nondeductible employee contributions and
        matching contributions for Plan Years beginning after the Plan Year in
        which this Plan is adopted by the Employer. Employee contributions for
        Plan Years beginning after December 31, 1986, together with any matching
        contributions as defined in Section 4~(m) of the Code, will be limited
        so as to meet the nondiscrimination test of Section 401(m) of the Code.

        A separate account will be maintained by the Plan Administrator for the
        nondeductible employee contributions of each Participant.

        A Participant may, upon a written request submitted to the Plan
        Administrator, withdraw the lesser of the portion of his Individual
        Account attributable to his nondeductible employee contributions or the
        amount he contributed as nondeductible employee contributions.

        Employee contributions and earnings thereon will be nonforfeitable at
        all times. No Forfeiture will occur solely as a result of an Employee's
        withdrawal of employee contributions.

        The Plan Administrator will not accept deductible employee contributions
        which are made for a taxable year beginning after December 31, 1986.
        Contributions made prior to that date will be maintained in a separate
        account which will be non-forfeitable at all times. The account will
        share in the gains and losses of the Fund in the same manner as
        described in Section 4.03 of the Plan. No part of the deductible
        employee contribution account will be used to purchase life insurance.
        Subject to Section 6.05, joint and survivor annuity requirements (if
        applicable), the Participant may withdraw any part of the deductible
        employee contribution account by making a written application to the
        Plan Administrator.

3.03    ROLLOVER CONTRIBUTIONS

        If the Plan Administrator so permits in a uniform and nondiscriminatory
        manner, a Participant may contribute a rollover contribution to the
        Plan; provided that such Employee submits a written certification,
        satisfactory to the Trustee (or Custodian), that the contribution
        qualifies as a rollover contribution.

        A separate account shall be maintained by the Plan Administrator for
        each Participant's rollover contributions which will be nonforfeitable
        at all times. Such account will share in the income and gains and losses
        of the Fund in the manner described in Section 4.03 and shall be subject
        to the Plan's provisions governing distributions.

        For purposes of this Section 3.03, "rollover contribution" means a
        contribution described in Sections 402(a)(5), 403(a)(4) or 408(d)(3) of
        the Code or in any other provision which may be added to the Code which
        may authorize rollovers to the Plan



                                       17
<PAGE>   23

3.04    TRANSFER CONTRIBUTIONS

        If the Plan Administrator so permits in a uniform and nondiscriminatory
        manner, the Trustee (or Custodian, if applicable) may receive any
        amounts transferred to it from the trustee or custodian of another plan
        qualified under Code Section 401(a).

        A separate account shall be maintained by the Plan Administrator for
        each Participant's transfer contributions which will be nonforfeitable
        at all times. Such account will share in the income and gains and losses
        of the Fund in the manner described ii Section 4.03 and shall be subject
        to the Plan's provisions governing distributions.

3.05    LIMITATION ON ALLOCATIONS

        A. If the Participant does not participate in, and has never
           participated in another qualified plan maintained by the Employer or
           a welfare benefit fund, as defined in Section 419(e) of the Code
           maintained by the Employer, or an individual medical account, as
           defined in Section 5(l)(2) of the Code, maintained by the Employer,
           which provides an annual addition as defined in Section 3.05(E)(1),
           the following rules shall apply.

          1.   The amount of annual additions which may be credited to the
               Participant's Individual Account for any limitation year will not
               exceed the lesser of the maximum permissible amount or any other
               limitation contained in this Plan. If the Employer Contribution
               that would otherwise be contributed or allocated to the
               Participant's Individual Account would cause the annual additions
               for the limitation year to exceed the maximum permissible amount,
               the amount contributed or allocated will be reduced so that the
               annual additions for the limitation year will equal the maximum
               permissible amount.

          2.   Prior to determining the Participant's actual compensation for
               the limitation year, the Employer may determine the maximum
               permissible amount for a Participant on the basis of a reasonable
               estimation of the Participant's Compensation for the limitation
               year, uniformly determined for all participants similarly
               situated.

          3.   As soon as is administratively feasible after the end of the
               limitation year, the maximum permissible amount for the
               limitation year will be determined on the basis of the
               Participant's actual compensation for the limitation year.

          4.   If pursuant to Section 3.05(A)(3) or as a result of the
               allocation of Forfeitures there is an excess amount, the excess
               will be disposed of as follows:

               a.   Any nondeductible voluntary employee contributions, to the
                    extent they would reduce the excess amount, will be returned
                    to the Participant;

               b.   If after the application of paragraph (a) an excess amount
                    still exists, and the Participant is covered by the Plan 
                    the end of the limitation year, the



                                       18
<PAGE>   24

                    excess amount in the Participant's Individual Account will
                    be used to reduce Employer Contributions (including any
                    allocation of Forfeitures) for such Participant in the
                    next limitation year and each succeeding limitation
                    year if necessary.

               c.   If after the application of paragraph (a) an excess amount
                    still exists, and the Participant is not covered by the Plan
                    at the end of a limitation year, the excess amount will be
                    held unallocated in a suspense account. The suspense account
                    will be applied to reduce future Employer Contributions
                    (including allocation of any Forfeitures) for all remaining
                    Participants in the next limitation year, and each
                    succeeding limitation year if necessary;

               d.   If a suspense account is in existence at any time during a
                    limitation year pursuant to this Section, it will not
                    participate in the allocation of the Fund's investment gains
                    and losses. If a suspense account is in existence at any
                    time during a particular limitation year, all amounts in the
                    suspense account must be allocated and reallocated to
                    Participants' Individual Accounts before any Employer
                    Contributions or any Employee contributions may be made to
                    the Plan for that limitation year. Excess amounts may not be
                    distributed to Participants or former Participants.

        B. If, in addition to this Plan, the Participant is covered under
           another qualified regional prototype defined contribution plan
           maintained by the Employer, a welfare benefit fund, as defined in
           Section 419(e) of the Code maintained by the Employer, or an
           individual medical account, as defined in Section 415(l)(2) of the
           Code, maintained by the Employer, which provides an annual addition
           as defined in Section 3.05(E)(1), during any limitation year, the
           following rules apply:

          1.   The annual additions which maybe credited to a Participant's
               Individual Account under this Plan for any such limitation year
               will not exceed the maximum permissible amount reduced by the
               annual additions credited to a Participant's Individual Account
               under the other plans and welfare benefit funds for the same
               limitation year. If the annual additions with respect to the
               Participant under other defined contribution plans and welfare
               benefit funds maintained by the employer are less than the
               maximum permissible amount and the Employer Contribution that
               would otherwise be contributed or allocated to the Participant's
               Individual Account under this Plan would cause the annual
               additions for the limitation year to exceed this limitation, the
               amount contributed or allocated will be reduced so that the
               annual additions under all such plans and funds for the
               limitation year will equal the maximum permissible amount. If the
               annual additions with respect to the Participant under such other
               defined contribution plans and welfare benefit funds in the
               aggregate are equal to or greater than the maximum permissible
               amount, no amount will be contributed or allocated to the
               Participant's Individual Account under this Plan for the
               limitation year.

                                       19
<PAGE>   25

           2.  Prior to determining the Participant's actual compensation for
               the limitation year, the Employer may determine the maximum
               permissible amount for a Participant in the manner described in
               Section 3.05(A)(2).

           3.  As soon as is administratively feasible after the end of the
               limitation year, the maximum permissible amount for the
               limitation year will be determined on the basis of the
               Participant's actual compensation for the limitation year.

           4.  If, pursuant to Section 3.05(B)(3) or as a result of the
               allocation of Forfeitures, a Participant's annual additions under
               this Plan and such other plans would result in an excess amount
               for a limitation year, the excess amount will be deemed to
               consist of the annual additions last allocated, except that
               annual additions attributable to a welfare benefit fund or
               individual medical account will be deemed to have been allocated
               first regardless of the actual allocation date

           5.  If an excess amount was allocated to a Participant on an
               allocation date of this Plan which coincides with an allocation
               date of another plan, the excess amount attributed to this Plan
               will be the product of,

                  a.  the total excess amount allocated as of such date, times

                  b.  the ratio of (i) the annual additions allocated to the
                      Participant for the limitation year as of such date under
                      this Plan to (ii) the total annual additions allocated to
                      the Participant for the limitation year as of such date
                      under this and all the other qualified regional prototype
                      defined contribution plans.

           6.  Any excess amount attributed to this Plan will be disposed in the
               manner described in Section 3.05(A)(4).

        C. If the Participant is covered under another qualified defined
           contribution plan maintained by the Employer which is not a regional
           prototype plan, annual additions which may be credited to the
           Participant's Individual Account under this Plan for any limitation
           year will be limited in accordance with Sections 3.05(B)(1) through
           3.05(B)(6) as though the other plan were a regional prototype plan
           unless the Employer provides other limitations in the Section of the
           Adoption Agreement titled "Limitation on Allocation More Than One
           Plan."

        D. If the Employer maintains, or at any time maintained, a qualified
           defined benefit plan covering any Participant in this Plan, the sum
           of the Participant's defined benefit plan fraction and defined
           contribution plan fraction will not exceed 1.0 in any limitation
           year. The annual additions which may be credited to the Participant's
           Individual Account under this Plan for any limitation year will be
           limited in accordance with the Section of the Adoption Agreement
           titled "Limitation on Allocation - More Than One Plan."

                                       20

        E. The following terms shall have the following meanings when used in
           this Section 3.05:

           1.  Annual additions: The sum of the following amounts credited to a
               Participant's Individual Account for the limitation year:

               a.   Employer Contributions,

               b.   Employee contributions,

               c.   Forfeitures, and

               d.   amounts allocated, after March 31, 1984, to an individual
                    medical account, as defined in Section 415(l)(2) of the
                    Code, which is part of a pension or annuity plan maintained
                    by the Employer are treated as annual additions to a defined
                    contribution plan. Also amounts derived from contributions
                    paid or accrued after December 31, 1985, in taxable years
                    ending after such date, which are attributable to
                    post-retirement medical benefits, allocated to the separate
                    account of a key employee, as defined in Section 419A(d)(3)
                    of the Code, under a welfare benefit fund, as defined in
                    Section 419(e) of the Code, maintained by the Employer are
                    treated as annual additions to a defined contribution plan.

                    For this purpose, any excess amount applied under Section
                    3.05(A)(4) or 3.05(B)(6) in the limitation year to reduce
                    Employer Contributions will be considered annual additions
                    for such limitation year.

           2.  Compensation: A Participant's earned income, wages, salaries, and
               fees for professional services and other amounts received for
               personal services actually rendered in the course of employment
               with the Employer maintaining the Plan (including, but not
               limited to, commissions paid salesmen, compensation for services
               on the basis of a percentage of profits, commissions on insurance
               premiums, tips and bonuses), and excluding the following:

               a.   Employer contributions to a plan of deferred compensation
                    which are not includible in the Employee's gross income for
                    the taxable year in which contributed, or employer
                    contributions under a simplified employee pension plan to
                    the extent such contributions are deductible by the
                    Employee, or any distributions from a plan of deferred
                    compensation;

               b.   Amounts realized from the exercise of a nonqualified stock
                    option, or when restricted stock (or property) held by the
                    Employee either becomes freely transferable or is no longer
                    subject to a substantial risk of forfeiture;

               c.   Amounts realized from the sale, exchange or other
                    disposition of stock acquired under a qualified stock
                    option; and

                                       21
<PAGE>   27

               d.   Other amounts which received special tax benefits, or
                    contributions made by the Employer (whether or not under a
                    salary reduction agreement) towards the purchase of an
                    annuity described in Section 403(b) of the Code (whether or
                    not the amounts are actually excludible from the gross
                    income of the Employee).

                    For purposes of applying the limitations of this Section
                    3.05, compensation for a limitation year is the compensation
                    actually paid or includible in gross income during such
                    limitation year.

                    Notwithstanding the preceding sentence, compensation for a
                    Participant in a defined contribution plan who is
                    permanently and totally disabled (as defined in Section
                    22(e)(3) of the Code) is the compensation such Participant
                    would have received for the limitation year if the
                    Participant had been paid at the rate of compensation paid
                    immediately before becoming permanently and totally
                    disabled; such imputed compensation for the disabled
                    participant may be taken into account only if the
                    Participant is not a Highly Compensated Employee (as defined
                    in Section 414(q) of the Code) and contributions made on
                    behalf of such Participant are nonforfeitable when made.

           3.  Defined benefit fraction: A fraction, the numerator of which is
               the sum of the Participant's projected annual benefits under all
               the defined benefit plans (whether or not terminated) maintained
               by the Employer, and the denominator of which is the lesser of
               125% of the dollar limitation determined for the limitation year
               under Section 415(b) and (d) of the Code or 140% of the highest
               average compensation, including any adjustments under Section
               415(0) of the Code.

               Notwithstanding the above, if the Participant was a Participant
               as of the first day of the first limitation year beginning after
               December 31, 1986, in one or more defined benefit plans
               maintained by the employer which were in existence on May 6,
               1986, the denominator of this fraction will not be less than 125%
               of the sum of the annual benefits under such plans which the
               participant had accrued as of the close of the last limitation
               year beginning before January 1, 1987, disregarding any changes
               in the terms and conditions of the plan after May 5, 1986. The
               preceding sentence applies only if the defined benefit plans
               individually and in the aggregate satisfied the requirements of
               Section 415 of the Code for all limitation years beginning before
               January 1, 1987.

           4.  Defined contribution dollar limitation: $30,000 or if greater,
               one-fourth of the defined benefit dollar limitation set forth in
               Section 415(b)(1) of the Code as in effect for the limitation
               year.

          5.   Defined contribution fraction: A fraction, the numerator of which
               is the sum of the annual additions to the Participant's account
               under all the defined contribution plans (whether or not
               terminated) maintained by the Employer for the current and 



                                       22
<PAGE>   28

               all prior limitation years (including the annual additions
               attributable to the Participant's nondeductible employee
               contributions to all defined benefit plans, whether or not
               terminated, maintained by the Employer, and the annual additions
               attributable to all welfare benefit funds, as defined in Section
               419(e) of the Code, and individual medical accounts, as defined
               in Section 415(l)(2) of the Code, maintained by the Employer),
               and the denominator of which is the sum of the maximum aggregate
               amounts for the current and all prior limitation years of service
               with the Employer (regardless of whether a defined contribution
               plan was maintained by the Employer). The maximum aggregate
               amount in any limitation year is the lesser of 125% of the dollar
               limitation determined under Section 415(b) and (d) of the Code in
               effect under Section 415(c)(1)(A) of the Code or 35% of the
               Participant's compensation for such year.

               If the Employee was a participant as of the end of the first day
               of the first limitation year beginning after December 31, 1986,
               in one or more defined contribution plans maintained by the
               Employer which were in existence on May 6, 1986, the numerator of
               this fraction will be adjusted if the sum of this fraction and
               the defined benefit fraction would otherwise exceed 1.0 under the
               terms of this Plan. Under the adjustment, an amount equal to the
               product of (1) the excess of the sum of the fractions over 1.0
               times (2) the denominator of this fraction, will be permanently
               subtracted from the numerator of this fraction. The adjustment is
               calculated using the fractions as they would be computed as of
               the end of the last limitation year beginning before January 1,
               1987, and disregarding any changes in the terms and conditions of
               the Plan made after May 5, 1986, but using the Section 415
               limitation applicable to the first limitation year beginning on
               or after January 1, 1987. The annual addition for any limitation
               year beginning before January 1, 1987, shall not be recomputed to
               treat all employee contributions as annual additions.

          6.   Employer: For purposes of this Section 3.05, Employer shall mean
               the Employer that adopts this Plan, and all members of a
               controlled group of corporations (as defined in Section 414~) of
               the Code as modified by Section 415(h)), all commonly controlled
               trades or businesses (as defined in Section 414(c) as modified by
               Section 415(h)) or affiliated service groups (as defined in
               Section 414(m)) of which the adopting Employer is a part, and any
               other entity required to be aggregated with the Employer pursuant
               to regulations under Section 414(0) of the Code.

           7.  Excess amount: The excess of the Participant's annual additions
               for the limitation year over the maximum permissible amount.

           8.  Highest average compensation: The average compensation for the
               three consecutive years of service with the Employer that
               produces the highest average.

                                       23
<PAGE>   29

           9.  Limitation year: A calendar year, or the 12-consecutive month
               period elected by the Employer in the Section of the Adoption
               Agreement titled "Limitation on Allocation - More Than One Plan."
               All qualified plans maintained by the-Employer must use the same
               limitation year. If the limitation year is amended to a different
               12-consecutive month period, the new limitation year must begin
               on a date within the limitation year in which the amendment is
               made

           10. Regional prototype plan: A plan the form of which is the subject
               of a favorable notification letter from the Internal Revenue
               Service.

           11. Maximum permissible amount: The maximum annual addition that may
               be contributed or allocated to a Participant's Individual Account
               under the Plan for any limitation year shall not exceed the
               lesser of:

                    a.   the defined contribution dollar limitation, or

                    b.   25% of the Participant's compensation for the
                         limitation year.

                         The compensation limitation referred to in (b)) shall
                         not apply to any contribution for medical benefits
                         (within the meaning of Section 401(h) or Section 
                         419A(f)(2) of the Code) which is otherwise treated as
                         an annual addition under Section 415(l)(1) or 419A(d)
                         (2) of the Code.

                         If a short limitation year is created because of an
                         amendment changing the limitation year to a different
                         12-consecutive month period, the maximum permissible
                         amount will not exceed the defined contribution dollar
                         limitation multiplied by the following fraction:

                  Number of months in the short limitation year
                                       12

           12. Projected annual benefit: The annual retirement benefit (adjusted
               to an actuarially equivalent straight life annuity if such
               benefit is expressed in a form other than a straight life annuity
               or qualified joint and survivor annuity) to which the Participant
               would be entitled under the terms of the Plan assuming:

                    a.   the Participant will continue employment until normal
                         retirement age under the Plan (or current age, if
                         later), and

                    b.   the Participant's compensation for the current
                         limitation year and all other relevant factors used to
                         determine benefits under the Plan will remain constant
                         for all future limitation years.

        F. If the Employer maintains a defined benefit plan which is paired with
           this Plan, the following rule shall apply. In any Plan Year in which
           the paired plans are Top-Heavy, (i.e., the Top-Heavy ratio, as
           defined in Section 10.08(C) of the Plan, exceeds 

                                       24
<PAGE>   30

          60%) the denominators of the defined benefit plan fraction (as defined
          in Section 3.05(E)(3) of the Plan) and the defined contribution plan
          fraction (as defined in Section 3.05(E)(5) of the Plan) shall be
          computed using 100% of the dollar limitation instead of 125%.

                                  SECTION FOUR
                INDIVIDUAL ACCOUNTS OF PARTICIPANTS AND VALUATION

4.01    INDIVIDUAL ACCOUNTS

        A. The Plan Administrator shall establish and maintain an Individual
           Account in the name of each Participant to reflect the total value of
           his interest in the Fund. Each Individual Account established
           hereunder shall consist of such subaccounts as may be needed for each
           Participant including:

           1.  a subaccount to reflect Employer Contributions and Forfeitures
               allocated on behalf of a Participant;

           2.  a subaccount to reflect a Participant's rollover contributions;

           3.  a subaccount to reflect a Participant's transfer contributions;

           4.  a subaccount to reflect a Participant's nondeductible employee
               contributions; and

           5.  a subaccount to reflect a Participant's deductible employee
               contributions.

           Such subaccounts are primarily for accounting purposes, and do not
           necessarily require a segregation of the Fund.

        B. The Plan Administrator may establish additional accounts as it may
           deem necessary for the proper administration of the Plan, including,
           but not limited to, a suspense account for Forfeitures as required
           pursuant to Section 6.01(D).

4.02    VALUE ON OF FUND

        The Fund will be valued each Valuation Date at fair market value.

4.03    VALUATION OF INDIVIDUAL ACCOUNTS

        A. Where all or a portion of the assets of a Participant's Individual
           Account are invested in a Separate Fund for the Participant, then the
           value of that portion of such Participant's Individual Account at any
           relevant time equals the sum of the fair market values of the assets
           in such Separate Fund, less any applicable charges or penalties.

        B. The fair market value of the remainder of each Individual Account is
           determined in the following manner:

                                       25
<PAGE>   31

           1.  First, the portion of the Individual Account invested in each
               Investment Fund as of the previous Valuation Date is determined.
               Each such portion is reduced by any withdrawal made from the
               applicable Investment Fund to or for the benefit of a Participant
               or his Beneficiary, further reduced by any amounts forfeited by
               the Participant pursuant to Section 6.01(D) and further reduced
               by any transfer to another Investment Fund since the previous
               Valuation Date and is increased by any amount transferred from
               another Investment Fund since the previous Valuation Date. The
               resulting amounts are the net Individual Account portions
               invested in the Investment Funds.

          2.   Secondly, the net Individual Account portions invested in each
               Investment Fund are adjusted upwards or down-wards, pro rata
               (i.e., ratio of each net Individual Account portion to the sum of
               all net Individual Account portions) so that the sum of all the
               net Individual Account portions invested in an Investment Fund
               will equal the then fair market value of the Investment Fund.
               Notwithstanding the previous sentence, for the first Plan Year
               only, the net Individual Account portions shall be the sum of all
               contributions made to each Participant's Individual Account
               during the first Plan Year.

          3.   Thirdly, any contributions to the Plan and Forfeitures are
               allocated in accordance with the appropriate allocation
               provisions of Section 3. For purposes of Section 4, contributions
               made by the Employer for any Plan Year but after that Plan Year
               will be considered to have been made on the last day of that Plan
               Year regardless of when paid to the Trustee (or Custodian, if
               applicable).

               Amounts contributed between Valuation Dates will not be credited
               with investment gains or losses until the next following
               Valuation Date.

           4.  Finally, the portions of the Individual Account invested in each
               Investment Fund (determined in accordance with (1), (2) and (3)
               above) are added together.

4.04    SEGREGATION OF ASSETS

        If a Participant elects a mode of distribution other than a lump sum,
        the Plan Administrator may place that Participant's account balance into
        a segregated Investment Fund for the purpose of maintaining the
        necessary liquidity to provide benefit installments on a periodic basis.

4.05    STATEMENT OF INDIVIDUAL ACCOUNTS

        No later than 270 days after the close of each Plan Year, the Plan
        Administrator shall furnish a statement to each Participant indicating
        the Individual Account balances of such Participant as of the last
        Valuation Date in such Plan Year.

                                       26
<PAGE>   32

4.06    MODIFICATION OF METHOD FOR VALUING INDIVIDUAL ACCOUNTS

        If necessary or appropriate, the Plan Administrator may establish
        different or additional procedures (which shall be uniform and
        nondiscriminatory) for determining the fair market value of the
        Individual Accounts.

                                  SECTION FIVE
                              TRUSTEE OR CUSTODIAN

5.01    CREATION OF FUND

        By adopting this Plan, the Employer establishes the Fund which shall
        consist of the assets of the Plan held by the Trustee (or Custodian, if
        applicable) pursuant to this Section 5. Assets within the Fund maybe
        pooled on behalf of all Participants, earmarked on behalf of each
        Participant or be a combination of pooled and earmarked. To the extent
        that assets are earmarked for a particular Participant, they will be
        held in a Separate Fund for that Participant.

        No part of the corpus or income of the Fund may be used for, or diverted
        to, purposes other than for the exclusive benefit of Participants or
        their Beneficiaries.

5.02    INVESTMENT AUTHORITY

        Except as provided in Section 5.14 (relating to individual direction of
        investments by Participants), the Employer not the Trustee (or
        Custodian, if applicable), shall have exclusive management and control
        over the investment of the Fund into permitted investment.
        Notwithstanding the preceding sentence, a Trustee with full trust powers
        (under applicable law) make an agreement with the Employer whereby the
        Trustee will manage the investment of all or a portion of the Fund An'
        such agreement shall be in writing and set forth such matters as the
        Trustee deems necessary or desirable.

5.03    FINANCIAL ORGANIZATION CUSTODIAN OR TRUSTEE WITHOUT FULL TRUST POWERS

        This Section 5.03 applies where a financial organization has indicated
        in the Adoption Agreement that it will serve, with respect to this Plan,
        as Custodian or as Trustee without full trust powers (under applicable
        law). Hereinafter, a financial organization Trustee without full trust
        powers (under applicable law) shall be referred to as a Custodian.

        A. PERMISSIBLE INVESTMENTS - The assets of the Plan shall be invested
           only in those investments which are available through the Custodian
           in the ordinary course of business which the Custodian may legally
           hold in a qualified plan and which the Custodian chooses to make
           available to Employers for qualified plan investments.

                                       27
<PAGE>   33

        B. RESPONSIBILITIES OF THE CUSTODIAN - The responsibilities of the
           Custodian shall be limited to the following:

           1.  To receive Plan contributions and to hold, invest and reinvest

        of the assets of the Fund then held by him as expeditiously as possible
        to the successor Trustee (or Custodian) after paying or reserving such
        reasonable amount as he shall deem necessary to provide for the expense
        in the settlement of the accounts and the amount of any compensation due

        hands under this Plan. If the amount reserved shall be in excess of the
        amount actually needed, the former Trustee (or Custodian) shall return
        such excess to the successor Trustee (or Custodian).

        it is merged with or bought by another organization (or comes under the
        control of any federal or state agency), that organization shall serve
        as the successor Trustee (or Custodian) of this Plan, but only if it is
        the type of organization that can so serve under applicable law.

        custodian pursuant to Section l.4~42(n) of the Income Tax Regulations,
        the Employer will appoint a successor Trustee (or Custodian) upon
        notification by the Commissioner of Internal Revenue that such
        substitution is required because the Trustee (or Custodian) has failed
        to comply with the requirements of Section 1.401-12(n) or is not keeping
        such records or making such returns or rendering such statements as are
        required by forms or regulations.

5.13    MATTERS RELATING TO INSURANCE

        A. If a life insurance policy is to be purchased for a Participant, the
           aggregate premium for certain life insurance for each Participant
           must be less than a certain percentage of the aggregate Employer

               pay the premiums attributable to them.

           2.  Term and Universal Life Insurance - No more than 250/0 of the
               aggregate Employer Contributions and Forfeitures allocated to any

               on term life insurance contracts, universal life insurance
               contracts, and all other life insurance contracts which are not
               ordinary life.

           3.  Combination - The sum of 50% of the ordinary life insurance
               premiums and all other life insurance premiums will not exceed
               25% of the aggregate Employer Contributions and Forfeitures
               allocated to any Participant's Individual Account.

        B. Any dividends or credits earned on insurance contracts for a
           Participant shall be allocated to such Participant's Individual
           Account.

        C. Subject to Section 6.05, the contracts on a Participant's life will
           be converted to cash or an annuity or distributed to the Participant
           upon commencement of benefits.

        D. The Trustee (or Custodian, if applicable) shall apply for and will be
           the owner of any insurance contract(s) purchased under the terms of
           this Plan. The insurance contract(s) must provide that proceeds will
           be payable to the Trustee (or Custodian), however, the Trustee (or
           Custodian) shall be required to pay over all proceeds of the
           contract(s) to the Participant's designated Beneficiary in accordance
           with the distribution provisions of this Plan. A Participant's spouse
           will be the designated Beneficiary of the proceeds in all
           circumstances unless a qualified election has been made in accordance
           with Section 6.05, Joint and Survivor Annuity Requirements, if
           applicable. Under no circumstances shall the Fund retain any part of
           the proceeds. In the event of any conflict between the terms of this
           Plan and the terms of any insurance contract purchased hereunder, the
           Plan provisions shall control.

        E. The Employer may direct the Trustee (or Custodian) to sell and
           distribute insurance or annuity contracts to a Participant (or other
           party as may be permitted) in accordance with applicable law or
           regulations.

5.14    DIRECTION OF INVESTMENTS BY PARTICIPANT

        If so indicated in the Adoption Agreement, each Participant may
        individually direct the Trustee (or Custodian, if applicable) regarding
        the investment of part or all of his Individual Account. To the extent
        so directed, the Employer, Plan Administrator, Trustee (or Custodian)
        and all other fiduciaries are relieved of their fiduciary responsibility
        under Section 404 of ERISA.

        The Plan Administrator shall direct that a Separate Fund be established
        in the name of each Participant who directs the investment of part or
        all of his Individual Account. Each Separate Fund shall be charged or
        credited (as appropriate) with the earnings, gains, losses or expenses
        attributable to such Separate Fund. No fiduciary shall be liable for any
        loss which results from a Participant's individual direction. The assets
        subject to individual direction shall not be invested in collectibles as
        that term is defined in Section 408(m) of the Code.

        The Plan Administrator shall establish such uniform and
        nondiscriminatory rules relating to individual direction as it deems
        necessary or advisable including, but not limited to, rules describing
        (1) which portions of Participant's Individual Account can be
        individually directed; (2) the frequency of investment changes; (3) the
        forms and procedures for making investment changes; and (4) the effect
        of a Participant's failure to make a valid direction.

        The Plan Administrator may, in a uniform and nondiscriminatory manner,
        limit the available investments for Participants' individual direction
        to certain specified investment options (including, but not limited to,
        certain mutual funds, investment contracts, deposit accounts and group
        trusts). The Plan Administrator may permit, in a uniform and
        nondiscriminatory manner, a Beneficiary of a deceased Participant to
        individually direct in accordance with this Section.

                                   SECTION SIX
                            VESTING AND DISTRIBUTION

6.01    DISTRIBUTION TO PARTICIPANT

        A. WHEN DISTRIBUTABLE

           1.  Entitlement to Distribution - The Vested portion of a
               Participant's Individual Account shall be distributable to the
               Participant upon the occurrence of any of the following events:

                  a.  the Participant's Termination of Employment;

                  b.  the Participant's attainment of Normal Retirement Age;

                  c.  the Participant's Disability; or

                                       36
<PAGE>   42

                  d.  the termination of the Plan.

           2.  Written Request: When Distributed - A Participant entitled to
               distribution who wishes to receive a distribution must submit a
               written request to the Plan Administrator. Such request shall be
               made upon a form provided by the Plan Administrator. Upon a valid
               request, the Plan Administrator shall direct the Trustee (or
               Custodian, if applicable) to commence distribution no later than
               90 days following the later of:

                  a.   the close of the Plan Year within which the event occurs
                       which entitles the Participant to distribution; or

                  b.   the close of the Plan Year in which the request is
                       received.

           3.  Special Rules For Withdrawals During Service - If this is a
               profit sharing plan and the Adoption Agreement so provides, a
               Participant who is not otherwise entitled to a distribution under
               Section 6.01(A)(1) may elect to receive a distribution of all or
               a part of the Vested portion of his Individual Account, subject
               to the requirements of Section 6 05 and further subject to the
               following limits:

                  a.  Participant for 5 or more years. An Employee who has been
                      a Participant in the Plan for 5 or more years may withdraw
                      up to his entire Vested portion of his Individual Account.

                  b.  Participant for less than 5 years. An Employee who has
                      been a Participant in the Plan for less than 5 years may
                      withdraw only the amount which has been in his Vested
                      Individual Account attributable to Employer Contributions
                      for at least 2 full Plan Years.

                      However, if the distribution is on account of hardship,
                      the Participant may withdraw up to his entire Vested
                      portion of his Individual Account. For purposes of the
                      preceding sentence, hardship is defined as an immediate
                      and heavy financial need of the Participant where such
                      Participant lacks other available resources. The following
                      are the only financial needs considered immediate and
                      heavy: expenses incurred or necessary for medical care,
                      described in Section 213(d) of the Code, of the Employee,
                      the Employee's spouse or dependents; the purchase
                      (excluding mortgage payments) of a principal residence for
                      the Employee; payment of tuition and related educational
                      fees for the next 12 months of post-secondary education
                      for the Employee, the Employee's spouse, children or
                      dependents; or the need to prevent the eviction of the
                      Employee from, or a foreclosure on the mortgage of, the
                      Employee's principal residence.

                      A distribution will be considered as necessary to satisfy
                      an immediate and heavy financial need of the Employee only
                      if:

                                       37
<PAGE>   43

                  1)  The employee has obtained all distributions, other than
                      hardship distributions, and all nontaxable loans under all
                      plans maintained by the Employer;

                  2)  The distribution is not in excess of the amount of an
                      immediate and heavy financial need (including amounts
                      necessary to pay any federal, state or local income taxes
                      or penalties reasonably anticipated to result from the
                      distribution)

           4.  Commencement of Benefits - Notwithstanding any other provision,
               unless the Participant elects otherwise, distribution of benefits
               will begin no later than the 60th day after the latest of the
               close of the Plan Year in which:

                  a.  the Participant attains Normal Retirement Age;

                  b.  occurs the 10th anniversary of the year in which the
                      Participant commenced participation in the Plan; or

                  c. the Participant incurs a Termination of Employment.

                      Notwithstanding the foregoing, the failure of a
                      Participant and spouse to consent to a distribution while
                      a benefit is immediately distributable, within the meaning
                      of Section 6.02(B), shall be deemed to be an election to
                      defer commencement of payment of any benefit sufficient to
                      satisfy this Section 6.01(A)(4).

        B. DETERMINING THE VESTED PORTION - In determining the Vested portion of
           a Participant's Individual Account, the following rules apply:

           1.  Employer Contributions and Forfeitures - The Vested portion of a
               Participant's Individual Account derived from Employer
               Contributions and Forfeitures is determined by applying the
               vesting schedule selected in the Adoption Agreement (or the
               vesting schedule described in Section 6.01(C) if the Plan is a
               Top-Heavy Plan).

           2.  Rollover and Transfer Contributions - A Participant is fully
               Vested in his rollover contributions and transfer contributions.

           3.  Fully Vested Under Certain Circumstances - A Participant is fully
               Vested in his Individual Account if any of the following occurs:

                  a.  the Participant reaches Normal Retirement Age;

                  b.  the Participant incurs a Disability;

                  c.  the Participant dies;

                                       38
<PAGE>   44

                  d.  the Plan is terminated or partially terminated; or

                  e.  there exists a complete discontinuance of contributions
                      under the Plan (if this Plan is a profit sharing plan).

           4.  Participants in a Prior Plan - If a Participant was a participant
               in a Prior Plan on the Effective Date, his Vested percentage
               shall not be less than it would have been under such Prior Plan
               as computed on the Effective Date.

        C. MINIMUM VESTING SCHEDULE FOR TOP-HEAVY PLANS - The following vesting
           provisions apply for any Plan Year in which this Plan is a Top-Heavy
           Plan.

           Notwithstanding the other provisions of this Section 6.01 or the
           vesting schedule selected in the Adoption Agreement (unless those
           provisions or that schedule provide for more rapid vesting), a
           Participant's Vested portion of his Individual Account attributable
           to Employer Contributions and Forfeitures shall be determined in
           accordance with the following minimum vesting schedule:
<TABLE>
<CAPTION>

                YEAR OF VESTING SERVICE                          VESTED PERCENTAGE

<S>                                                              <C>
                           1                                            0
                           2                                           20
                           3                                           40
                           4                                           60
                           5                                           80
                           6                                          100
</TABLE>

        This minimum vesting schedule applies to all benefits within the meaning
        of Section 411(a)(7) of the Code, except those attributable to employee
        contributions including benefits accrued before the effective date of
        Section ~6 of the Code and benefits accrued before the Plan became a
        Top-Heavy Plan. Further, no decrease in a Participant's Vested
        percentage may occur in the event the Plan's status as a Top-Heavy Plan
        changes for any Plan Year. However, this Section 6.01(C) does not apply
        to the Individual Account of any Employee who does not have an Hour of
        Service after the Plan has initially become a Top-Heavy Plan and such
        Employee's Individual Account attributable to Employer Contributions and
        Forfeitures will be determined without regard to this Section.

           If this Plan ceases to be a Top-Heavy Plan, then in accordance with
           the above restrictions, the vesting schedule as selected in the
           Adoption Agreement will govern. If the vesting schedule under the
           Plan shifts in or out of Top-Heavy status, such shift is an amendment
           to the vesting schedule and the election in Section 9.04 applies.

        D. BREAK IN VESTING SERVICE AND FORFEITURES - If a Participant incurs a
           Termination of Employment, any portion of his Individual Account
           which is not Vested shall be held in a suspense account. Such
           suspense account shall share in any increase or decrease 


                                       39
<PAGE>   45

           in the fair market value of the assets of the Fund in accordance with
           Section 4 of the Plan. The disposition of such suspense account shall
           be as follows:

           1.  No Breaks in Vesting Service - If a Participant neither receives
               nor is deemed to receive a distribution pursuant to Section
               6.01(D)(2) or (3) and the Participant returns to the service of
               the Employer before incurring 5 consecutive Breaks in Vesting
               Service, there shall be no Forfeiture and the amount in such
               suspense account shall be recredited to such Participant's
               Individual Account.

          2.   Cash-out of Certain Participants - If the value of the Vested
               portion of such Participant's Individual Account derived from
               Employee and Employer Contributions does not exceed $3,500, the
               Participant shall receive a distribution of the entire Vested
               portion of such Individual Account and the portion which is not
               Vested shall be treated as a Forfeiture. For purposes of this
               Section, if the value of the Vested portion of a Participant's
               Individual Account is zero, the Participant shall be deemed to
               have received a distribution of such Vested Individual Account. A
               Participant's Vested Individual Account balance shall not include
               accumulated deductible employee contributions within the meaning
               of Section 72(o)(5)(B) of the Code for Plan Years beginning prior
               to January 1, 1989.

           3.  Participants Who Elect to Receive Distributions - If such
               Participant elects to receive a distribution, in accordance with
               Section 6.02(B), of the value of the Vested portion of his
               Individual Account derived from Employee and Employer
               Contributions, the portion which is not Vested shall be treated
               as a Forfeiture.

          4.   Re-employed Participants - If a Participant receives or is deemed
               to receive a distribution pursuant to Section 6.01(D)(2) or (3)
               above and the Participant resumes employment covered under this
               Plan, the Participant's Employer-derived Individual Account
               balance will be restored to the amount on the date of
               distribution if the Participant repays to the Plan the full
               amount of the distribution attributable to Employer Contributions
               before the earlier of 5 years after the first date on which the
               Participant is subsequently re-employed by the Employer, or the
               date the Participant incurs 5 consecutive Breaks in Vesting
               Service following the date of the distribution.

               Amounts forfeited under Section 6.01(D) shall be allocated in
               accordance with Section 3.01(C) as of the last day of the Plan
               Year during which the Forfeiture arises. Any restoration of a
               Participant's Individual Account pursuant to Section 6.01(D)(4)
               shall be made from other Forfeitures, income or gain to the Fund
               or contributions made by the Employer.

        E. DISTRIBUTION PRIOR TO FULL VESTING - If a distribution is made to a
           Participant who was not then fully Vested in his Individual Account
           derived from Employer Contributions and the Participant may increase
           his Vested percentage in his Individual Account, then the following
           rules shall apply:

                                       40
<PAGE>   46

          1.   a separate account will be established for the Participant's
               interest in the Plan as of the time of the distribution, and

          2.   at any relevant time the Participant's Vested portion of the
               separate account will be equal to an amount ("X") determined by
               the formula: X=P (AB + (R x D)) - (R x D) where "P" is the Vested
               percentage at the relevant time, "AB" is the separate account
               balance at the relevant time; "D" is the amount of the
               distribution; and "R" is the ratio of the separate account
               balance at the relevant time to the separate account balance
               after distribution.

6.02    FORM OF DISTRIBUTION TO A PARTICIPANT

        A. VALUE OF INDIVIDUAL ACCOUNT DOES NOT EXCEED $3,500 - If the value of
           the Vested portion of a Participant's Individual Account derived from
           Employee and Employer Contributions does not exceed $3,500,
           distribution from the Plan shall be made to the Participant in a
           single lump sum in lieu of all other forms of distribution from the
           Plan.

        B. VALUE OF INDIVIDUAL ACCOUNT EXCEEDS $3,500

          1.   If the value of the Vested portion of a Participant's Individual
               Account derived from Employee and Employer Contributions exceeds
               (or at the time of any prior distribution exceeded) $3,500, and
               the Individual Account is immediately distributable, the
               Participant and the Participant's spouse (or where either the
               Participant or the spouse died, the survivor) must consent to any
               distribution of such Individual Account. The consent of the
               Participant and the Participant's spouse shall be obtained in
               writing within the 90-day period ending on the annuity starting
               date. The annuity starting date is the first day of the first
               period for which an amount is paid as an annuity or any other
               form. The Plan Administrator shall notify the Participant and the
               Participant's spouse of the right to defer any distribution until
               the Participant's Individual Account is no longer immediately
               distributable. Such notification shall include a general
               description of the material features, and an explanation of the
               relative values of, the optional forms of benefit available under
               the Plan in a manner that would satisfy the notice requirements
               of Section 417(a)(3) of the Code and shall be provided no less
               than 30 days and no more than 90 days prior to the annuity
               starting date. If a distribution is one to which Sections
               401(a)(11) and 417 of the Internal Revenue Code do not apply,
               such distribution may commence less than 30 days after the notice
               required under Section 1.411(a)41(c) of the Income Tax
               Regulations is given provided that:

                  a.  the Plan Administrator clearly informs the Participant
                      that the Participant has a right to a period of at least
                      30 days after receiving the notice to consider the
                      decision of whether or not to elect a distribution (and,
                      if applicable, a particular distribution option), and

                                       41
<PAGE>   47

                  b.  the Participant, after receiving the notice, affirmatively
                      elects a distribution.

                      Notwithstanding the foregoing, only the Participant need
                      consent to the commencement of a distribution in the form
                      of a qualified joint and survivor annuity while the
                      Individual Account is immediately distributable. Neither
                      the consent of the Participant nor the Participant's
                      spouse shall be required to the extent that a distribution
                      is required to satisfy Section 4~(a)(9) or Section 415 of
                      the Code. In addition, upon termination of this Plan if
                      the Plan does not offer an annuity option (purchased from
                      a commercial provider), the Participant's Individual
                      Account may, without the Participant's consent, be
                      distributed to the Participant or transferred to another
                      defined contribution plan (other than an employee stock
                      ownership plan as defined in Section 4975(e)(7) of the
                      Code) within the same controlled group.

                      An Individual Account is immediately distributable if any
                      part of the Individual Account could be distributed to the
                      Participant (or surviving spouse) before the Participant
                      attains or would have attained (if not deceased) the later
                      of Normal Retirement Age or age 62.

           2.  For purposes of determining the applicability of the foregoing
               consent requirements to distributions made before the first day
               of the first Plan year beginning after December ~, 1988, the
               Vested portion of a Participant's Individual Account shall not
               include amounts attributable to accumulated deductible employee
               contributions within the meaning of Section 72(o)(5)(B) of the
               Code.

        C. OTHER FORMS OF DISTRIBUTION TO PARTICIPANT - If the value of the
           Vested portion of a Participant's Individual Account exceeds $3,500
           and the Participant has properly waived the joint and survivor
           annuity, as described in Section 6.05, the Participant may request in
           writing that the Vested portion of his Individual Account be paid to
           him in one or more of the following forms of payment: (1) in a lump
           sum; (2) in installment payments over a period not to exceed the life
           expectancy of the Participant or the joint and last survivor life
           expectancy of the Participant and his designated Beneficiary; or (3)
           applied to the purchase of an annuity contract.

           Notwithstanding anything in this Section 6.02 to the contrary, a
           Participant cannot elect payments in the form of an annuity if the
           safe harbor rules of Section 6.05(F) apply.

6.03    DISTRIBUTIONS UPON THE DEATH OF A PARTICIPANT

        A. DESIGNATION OF BENEFICIARY - SPOUSAL CONSENT - Each Participant may
           designate, upon a form provided by and delivered to the Plan
           Administrator, one or more primary and contingent Beneficiaries to
           receive all or a specified portion of his Individual Account in the
           event of his death. A Participant may change or revoke


                                       42
<PAGE>   48

           such Beneficiary designation from time to time by completing and
           delivering the proper form to the Plan Administrator.

           In the event that a Participant wishes to designate a primary
           Beneficiary who is not his spouse, his spouse must consent in writing
           to such designation, and the spouse's consent must acknowledge the
           effect of such designation and be witnessed by a notary public.
           Notwithstanding this consent requirement, if the Participant
           establishes to the satisfaction of the Plan Administrator that such
           written consent may not be obtained because there is no spouse or the
           spouse cannot be located, no consent shall be required. Any change of
           Beneficiary will require a new spousal consent.

        B. PAYMENT TO BENEFICIARY - If a Participant dies before his entire
           Individual Account has been paid to him, such deceased Participant's
           Individual Account shall be payable to any surviving Beneficiary
           designated by the Participant, or, if no Beneficiary survives the
           Participant, to the Participant's estate.

        C. WRITTEN REQUEST: WHEN DISTRIBUTED - A Beneficiary of a deceased
           Participant entitled to a distribution who wishes to receive a
           distribution must submit a written request to the Plan Administrator.
           Such request shall be made upon a form provided by the Plan
           Administrator. Upon a valid request, the Plan Administrator shall
           direct the Trustee (or Custodian) to commence distribution no later
           than 90 days following the later of:

           1.  the close of the Plan Year within which the Participant dies; or

           2. the close of the Plan Year in which the request is received.

        D. LOCATION OF PARTICIPANT OR BENEFICIARY UNKNOWN - In the event that
           all, or any portion, of the distribution payable to a Participant or
           his Beneficiary hereunder shall, at the expiration of 5 years after
           it becomes payable, remain unpaid solely by reason of the inability
           of the Plan Administrator, after sending a registered letter, return
           receipt requested, to the last known address, and after further
           diligent effort, to ascertain the whereabouts of such Participant or
           his Beneficiary, the amount so distributable shall be forfeited and
           allocated in accordance with the terms of the Plan. In the event a
           Participant or Beneficiary is located subsequent to his benefit being
           forfeited, such benefit shall be restored; provided, however, if all
           or a portion of such amount has been lost by reason of escheat under
           state law, the Participant or Beneficiary shall cease to be entitled
           to the portion so lost.

6.04    FORM OF DISTRIBUTION TO BENEFICIARY

        A. VALUE OF INDIVIDUAL ACCOUNT DOES NOT EXCEED $3,500- If the value of
           the Participant's Individual Account derived from Employee and
           Employer Contributions does not exceed $3,500, the Plan Administrator
           shall direct the Trustee (or Custodian, if applicable) to make a
           distribution to the Beneficiary in a single lump sum in lieu of all
           other forms of distribution from the Plan.

                                       43
<PAGE>   49

        B. VALUE OF INDIVIDUAL ACCOUNT EXCEEDS $3,500 - If the value of a
           Participant's Individual Account derived from Employee' and Employer
           Contributions exceeds $3,500 the preretirement survivor annuity
           requirements of Section 6.05 shall apply unless waived in accordance
           with that Section or unless the safe harbor rules of Section 6.05(F)
           apply.

        C. OTHER FORMS OF DISTRIBUTION TO BENEFICIARY - If the value of a
           Participant's Individual Account exceeds $3,500 and the Participant
           has properly waived the preretirement survivor annuity, as described
           in Section 6.05 (if applicable), the Beneficiary may, subject to the
           requirements of Section 6.06, request in writing that the
           Participant's Individual Account be paid to him as follows: (1) in a
           lump sum; or (2) in installment payments over a period not to exceed
           the life expectancy of such Beneficiary.

6.05    JOINT AND SURVIVOR ANNUITY REQUIREMENTS

        A. The provisions of this Section shall apply to any Participant who is
           credited with at least one Hour of Eligibility Service with the
           Employer on or after August 23, 1984, and such other participants as
           provided in Section 6.05(G).

        B. QUALIFIED JOINT AND SURVIVOR ANNUITY - Unless an optional form of
           benefit is selected pursuant to a qualified election within the
           90-day period ending on the annuity starting date, a married
           Participant's Vested account balance will be paid in the form of a
           qualified joint and survivor annuity and an unmarried Participant's
           Vested account balance will be paid in the form of a life annuity.
           The Participant may elect to have such annuity distributed upon
           attainment of the earliest retirement age under the Plan.

        C. QUALIFIED PRERETIREMENT SURVIVOR ANNUITY - Unless an optional form of
           benefit has been selected within the election period pursuant to a
           qualified election, if a Participant dies before the annuity starting
           date then the Participant's Vested account balance shall be applied
           toward the purchase of an annuity for the life of the surviving
           spouse. The surviving spouse may elect to have such annuity
           distributed within a reasonable period after the Participant's death.

        D. DEFINITIONS

           1.  Election Period - The period which begins on the first day of the
               Plan Year in which the Participant attains age 35 and ends on the
               date of the Participant's death. If a Participant separates from
               service prior to the first day of the Plan year in which age 35
               is attained, with respect to the account balance as of the date
               of separation, the election period shall begin on the date of
               separation.

               Pre-age 35 waiver - A Participant who will not yet attain age 35
               as of the end of any current Plan Year may make a special
               qualified election to waive the qualified preretirement survivor
               annuity for the period beginning on the date of such 



                                       44
<PAGE>   50

               election and ending on the first day of the Plan Year in which
               the Participant will attain age 35. Such election shall not be
               valid unless the Participant receives a written explanation of
               the qualified preretirement survivor annuity in such terms as are
               comparable to the explanation required under Section 6.05(E)(1).
               Qualified preretirement survivor annuity coverage will be
               automatically reinstated as of the first day of the Plan Year in
               which the Participant attains age 35. Any new waiver on or after
               such date shall be subject to the full requirements of this
               Section 6.05.

           2.  Earliest Retirement Age - The earliest date on which, under the
               Plan, the Participant could elect to receive retirement benefits.

           3.  Qualified Election - A waiver of a qualified joint and survivor
               annuity or a qualified preretirement survivor annuity. Any waiver
               of a qualified joint and survivor annuity or a qualified
               preretirement survivor annuity shall not be effective unless: (a)
               the Participant's spouse consents in writing to the election, ~)
               the election designates a specific Beneficiary, including any
               class of beneficiaries or any contingent beneficiaries, which may
               not be changed without spousal consent (or the spouse expressly
               permits designations by the Participant without any further
               spousal consent); (c) the spouse's consent acknowledges the
               effect of the election; and (d) the spouse's consent is witnessed
               by a plan representative or notary public. Additionally, a
               Participant's waiver of the qualified joint and survivor annuity
               shall not be effective unless the election designates a form of
               benefit payment which may not be changed without spousal consent
               (or the spouse expressly permits designations by the Participant
               without any further spousal consent). If it is established to the
               satisfaction of a plan representative that there is no spouse or
               that the spouse cannot be located, a waiver will be deemed a
               qualified election.

               Any consent by a spouse obtained under this provision (or
               establishment that the consent of a spouse may not be obtained)
               shall be effective only with respect to such spouse. A consent
               that permits designations by the Participant without any
               requirement of further consent by such spouse must acknowledge
               that the spouse has the right to limit consent to a specific
               Beneficiary, and a specific form of benefit where applicable, and
               that the spouse voluntarily elects to relinquish either or both
               of such rights. A revocation of a prior waiver may be made by a
               Participant without the consent of the spouse at any time before
               the commencement of benefits. The number of revocations shall not
               be limited. No consent obtained under this provision shall be
               valid unless the Participant has received notice as provided in
               Section 6.05(E) below.

           4.  Qualified Joint and Survivor Annuity - An immediate annuity for
               the life of the Participant with a survivor annuity for the life
               of the spouse which is not less than 50010 and not more than 100%
               of the amount of the annuity which is payable during the joint
               lives of the Participant and the spouse and which is the amount
               of benefit which can be purchased with the Participant's vested
               account balance. The 



                                       45
<PAGE>   51

               percentage of the survivor annuity under the Plan shall be 500/0
               (unless a different percentage is elected by the Employer in the
               Adoption Agreement).

           5.  Spouse (surviving spouse) - The spouse or surviving spouse of the
               Participant, provided that a former spouse will be treated as the
               spouse or surviving spouse and a current spouse will not be
               treated as the spouse or surviving spouse to the extent provided
               under a qualified domestic relations order as described in
               Section 414(p) of the Code.

           6.  Annuity Starting Date - The first day of the first period for
               which an amount is paid as an annuity or any other form.

           7.  Vested Account Balance - The aggregate value of the Participant's
               Vested account balances derived from Employer and Employee
               contributions (including rollovers), whether Vested before or
               upon death, including the proceeds of insurance contracts, if
               any, on the Participant's life. The provisions of this Section
               6.05 shall apply to a Participant who is Vested in amounts
               attributable to Employer Contributions, Employee contributions
               (or both) at the time of death or distribution.

        E. NOTICE REQUIREMENTS

          1.   In the case of a qualified joint and survivor annuity, the Plan
               Administrator shall no less than 30 days and not more than 90
               days prior to the annuity starting date provide each Participant
               a written explanation of: (a) the terms and conditions of a
               qualified joint and survivor annuity; in) the Participant's right
               to make and the effect of an election to waive the qualified
               joint and survivor annuity form of benefit; (c) the rights of a
               Participant's spouse; and (d) the right to make, and the effect
               of, a revocation of a previous election to waive the qualified
               joint and survivor annuity.

           2.  In the case of a qualified preretirement survivor annuity as
               described in Section 6.05(C), the Plan Administrator shall
               provide each Participant within the applicable period for such
               Participant a written explanation of the qualified preretirement
               survivor annuity in such terms and in such manner as would be
               comparable to the explanation provided for meeting the
               requirements of Section 6.05(E)(l) applicable to a qualified
               joint and survivor annuity.

               The applicable period for a Participant is whichever of the
               following periods ends last: (a) the period beginning with the
               first day of the Plan Year in which the Participant attains age
               32 and ending with the close of the Plan Year preceding the Plan
               Year in which the Participant attains age 35; (0) a reasonable
               period ending after the individual becomes a Participant; (c) a
               reasonable period ending after Section 6.05(E)(3) ceases to 
               apply to the Participant; (d) a reasonable period ending after 
               this Section 6.05 first applies to the Participant. 
               Notwithstanding the foregoing, notice must be provided within 
               a reasonable period ending after 



                                       46
<PAGE>   52
               separation from service in the case of a Participant who
               separates from service before attaining age 35.

               For purposes of applying the preceding paragraph, a reasonable
               period ending after the enumerated events described in (b), (c)
               and (d) is the end of the two-year period beginning one year
               prior to the date the applicable event occurs, and ending one
               year after that date. In the case of a Participant who separates
               from service before the Plan Year in which age 35 is attained,
               notice shall be provided within the two-year period beginning one
               year prior to separation and ending one year after separation. If
               such a Participant thereafter returns to employment with the
               Employer, the applicable period for such Participant shall be
               redetermined.

          3.   Notwithstanding the other requirements of this Section 6.05(E),
               the respective notices prescribed by this Section 6.05(E), need
               not be given to a Participant if (a) the Plan "fully subsidizes"
               the costs of a qualified joint and survivor annuity or qualified
               preretirement survivor annuity, and in) the Plan does not allow
               the Participant to waive the qualified joint and survivor annuity
               or qualified preretirement survivor annuity and does not allow a
               married Participant to designate a nonspouse beneficiary. For
               purposes of this Section 6.05(E)(3), a plan fully subsidizes the
               costs of a benefit if no increase in cost, or decrease in
               benefits to the Participant may result from the Participant's
               failure to elect another benefit.

        F. SAFE HARBOR RULES

          1.   If the Employer so indicates in the Adoption Agreement, this
               Section 6.05(F) shall apply to a Participant in a profit sharing

                         occurring after the Participant's death in accordance
                         with the provisions of the Plan governing the

                         sharing plan if the plan is a direct or indirect
                         transferee of a defined benefit plan, money purchase

                         the Code. If this Section 6.05(F) is operative, then
                         the provisions of this Section 6.05 other than Section
                         6.05(G) shall be inoperative.

           2.  The Participant may waive the spousal death benefit described in
               this Section 6.05(F) at any time provided that no such waiver
               shall be effective unless it satisfies the conditions of Section
               6.05(D)(3) (other than the notification requirement referred to
               therein) that would apply to the Participant's waiver of the
               qualified preretirement survivor annuity.

           3.  For purposes of this Section 6.05(F), Vested account balance
               shall mean, in the case of a money purchase pension plan or a

               of the following requirements if benefits would have been payable
               in the form of a life annuity:

                  a.  Automatic Joint and Survivor Annuity - If benefits in the
                      form of a life annuity become payable to a married

                      1.   begins to receive payments under the Plan on or after

                           such benefits;

                      then such benefits will be received under this Plan in the
                      form of a qualified joint and survivor annuity, unless the
                      Participant has elected otherwise during the election
                      period. The election period must begin at least 6 months
                      before the Participant attains qualified early retirement
                      age and ends not more than 90 days before the commencement
                      of benefits. Any election hereunder will be in writing and

                      election period, to have a survivor annuity payable on
                      death. If the Participant elects the survivor annuity,
                      payments under such annuity must not be less than the
                      payments which would have been made to the spouse under
                      the qualified joint and survivor annuity if the
                      Participant had retired on the day before his or her
                      death. Any election under this provision will be in
                      writing and may be changed by the Participant at any time.

                      begins, and ends on the date the Participant terminates
                      employment.

                  c.  For purposes of Section 6.05(G)(4):

                             a. the earliest date, under the Plan, on which the
                                Participant may elect to receive retirement 
                                benefits,

                             b. the first day of the 120th month beginning 
                                before the Participant reaches Normal Retirement

                             c. the date the Participant begins participation.

                          2. Qualified joint and survivor annuity is an annuity

                             annuity for the life of the spouse as described in
                             Section 6.05 (D)(4) of this Plan.

        C. LIMITS ON DISTRIBUTION PERIODS - As of the first distribution
           calendar year, distributions, if not made in a single sum, may only
           be made over one of the following periods (or a combination thereof):

           1.  the life of the Participant,

               Participant, or

           4.  a period certain not extending beyond the joint and last survivor
               expectancy of the Participant and a designated Beneficiary.

        D. DETERMINATION OF AMOUNT TO BE DISTRIBUTED EACH YEAR - If the

           Participant's designated Beneficiary or (2) a period not extending
           beyond the life expectancy of the designated Beneficiary, the amount
           required to be distributed for each calendar year, beginning with
           distributions for the first distribution calendar year, must at least
           equal the quotient obtained by dividing the Participant's benefit by
           the applicable life expectancy.

        b. For calendar years beginning before January 1, 1989, if the
           Participant's spouse is not the designated Beneficiary, the method of
           distribution selected must assure that at least 50% of the present
           value of the amount available for distribution is paid within the
           life expectancy of the Participant.

        c. For calendar years beginning after December 31, 1988, the amount to
           be distributed each year, beginning with distributions for the first

           Participant shall be distributed using the applicable life expectancy
           in Section 6.06(D)(1)(a) above as the relevant divisor without regard
           to regulations 1.401(a)(9)-2.

        d. The minimum distribution required for the Participant's first
           distribution calendar year must be made on or before the
           Participant's required beginning date. The minimum distribution for
           other calendar years, including the minimum distribution for the
           distribution calendar year in which the Employee's required beginning
           date occurs, must be made on or before December 31 of that
           distribution calendar year.

        2. Other Forms - If the Participant's benefit is distributed in the form
           of an annuity purchased from an insurance company, distributions
           thereunder shall be made in accordance with the requirements of

        E.     DEATH DISTRIBUTION PROVISIONS

        1. Distribution Beginning Before Death - If the Participant dies after
           distribution of his or her interest has begun, the remaining portion
           of such interest will continue to be distributed at least as rapidly
           as under the method of distribution being used prior to the
           Participant's death.

        2. Distribution Beginning After Death - II the Participant dies before
           distribution of his or her interest begins, distribution of the
           Participant's entire interest shall be completed by December 31 of
           the calendar year containing the fifth anniversary of the


                                       51
<PAGE>   57

           Participant's death except to the extent that an election is made to
           receive distributions in accordance with (a) or (b) below:

           a.  if any portion of the Participant's interest is payable to a
               designated Beneficiary, distributions may be made over the life
               or over a period certain not greater than the life expectancy of
               the designated Beneficiary commencing on or before December 31 of
               the calendar year immediately following the calendar year in
               which the Participant died;

           b.  if the designated Beneficiary is the Participant's surviving
               spouse, the date distributions are required to begin in
               accordance with (a) above shall not be earlier than the later of
               (1) December 31 of the calendar year immediately following the
               calendar year in which the Participant dies or (2) December 31 of
               the calendar year in which the Participant would have attained
               age 70 1/2.

               If the Participant has not made an election pursuant to this
               Section 6.06(E)(2) by the time of his or her death, the
               Participant's designated Beneficiary must elect the method of
               distribution no later than the earlier of (1) December 31 of the
               calendar year in which distributions would be required to begin
               under this Section 6.06(E)(2), or (2) December 31 of the calendar
               year which contains the fifth anniversary of the date of death of
               the Participant. If the Participant has no designated
               Beneficiary, or if the designated Beneficiary does not elect a
               method of distribution, distribution of the Participant's entire
               interest must be completed by December ~ of the calendar year
               containing the fifth anniversary of the Participant's death.

        3. For purposes of Section 6.06(E)(2) above, if the surviving spouse
           dies after the Participant, but before payments to such spouse begin,
           the provisions of Section 6.06(E)(2), with the exception of paragraph
           (0) therein, shall be applied as if the surviving spouse were the
           Participant.

        4. For purposes of this Section 6.06(E), any amount paid to a child of
           the Participant will be treated as if it had been paid to the
           surviving spouse if the amount becomes payable to the surviving
           spouse when the child reaches the age of majority.

        5. For purposes of this Section 6.06(E), distribution of a Participant's
           interest is considered to begin on the Participant's required
           beginning date (or, if Section 6.06(E)(3) above is applicable, the
           date distribution is required to begin to the surviving spouse
           pursuant to Section 6.06(E)(2) above). If distribution in the form of
           an annuity irrevocably commences to the Participant before the
           required beginning date, the date distribution is considered to begin
           is the date distribution actually commences.

<PAGE>   58

        1. Applicable Life Expectancy - The life expectancy (or joint and last
           survivor expectancy) calculated using the attained age of the
           Participant (or designated Beneficiary) as of the Participant's (or
           designated Beneficiary's) birthday in the applicable calendar year
           reduced by one for each calendar year which has elapsed since the
           date life expectancy was first calculated. If life expectancy is
           being recalculated, the applicable life expectancy shall be the life
           expectancy as so recalculated. The applicable calendar year shall be
           the first distribution calendar year, and if life expectancy is being
           recalculated such succeeding calendar year.

        2. Designated Beneficiary - The individual who is designated as the
           Beneficiary under the Plan in accordance with Section 401(a)(9) of
           the Code and the regulations thereunder.

        3. Distribution Calendar Year - A calendar year for which a minimum
           distribution is required. For distributions beginning before the
           Participant's death, the first distribution calendar year is the
           calendar year immediately preceding the calendar year which contains
           the Participant's required beginning date. For distributions
           beginning after the Participant's death, the first distribution
           calendar year is the calendar year in which distributions are
           required to begin pursuant to Section 6.06(E) above.

        4. Life Expectancy - Life expectancy and joint and last survivor
           expectancy are computed by use of the expected return multiples in
           Tables V and VI of Section 1.72-9 of the Income Tax Regulations.

           Unless otherwise elected by the Participant (or spouse, in the case
           of distributions described in Section 6.06(E)(2)(b) above) by the
           time distributions are required to begin, life expectancies shall be
           recalculated annually. Such election shall be irrevocable as to the
           Participant (or spouse) and shall apply to all subsequent years. The
           life expectancy of a nonspouse Beneficiary may not be recalculated.

        5. Participant's Benefit

           a.  The account balance as of the last valuation date in the
               valuation calendar year (the calendar year immediately preceding
               the distribution calendar year) increased by the amount of any
               Contributions or Forfeitures allocated to the account balance as
               of dates in the valuation calendar year after the valuation date
               and decreased by distributions made in the valuation calendar
               year after the valuation date.

           b.  Exception for second distribution calendar year. For purposes of
               paragraph (a) above, if any portion of the minimum distribution
               for the first distribution calendar year is made in the second
               distribution calendar year on or before the required beginning
               date, the amount of the minimum distribution made in the second
               distribution calendar year shall be treated as if it had been
               made in the immediately preceding distribution calendar year.

        6. Required Beginning Date

           a.  General Rule - The required beginning date of a Participant is
               the first day of April of the calendar year following the
               calendar year in which the Participant attains age 70 1/2.

           b.  Transitional Rules - The required beginning date of a Participant
               who attains age 70 1/2 before January 1, 1988, shall be
               determined in accordance with (1) or (2) below:

                  1.  Non 5% Owners - The required beginning date of a
                      Participant who is not a 5% owner is the first day of
                      April of the calendar year following the calendar year in
                      which the later of retirement or attainment of age 70 1/2
                      occurs.

                  2.  5% Owners - The required beginning date of a Participant
                      who is a 5% owner during any year beginning after December
                      31, 1979, is the first day of April following the later
                      of:

                          a. the calendar year in which the Participant attains
                             age 70 1/2, or

                          b. the earlier of the calendar year with or within
                             which ends the Plan Year in which the Participant
                             becomes a 5% owner, or the calendar year in which
                             the Participant retires.

                             The required beginning date of a Participant who is
                             not a 5% owner who attains age 70 1/2 during 1988
                             and who has not retired as of January 1, 1989, is
                             April 1, 1990.

           c.  5% Owner - A Participant is treated as a 5% owner for purposes of
               this Section 6.06(F)(6) if such Participant is a 5% owner as
               defined in Section 416(i) of the Code (determined in accordance
               with Section ~6 but without regard to whether the Plan is
               top-heavy) at any time during the Plan Year ending with or within
               the calendar year in which such owner attains age 66 1/2 or any
               subsequent Plan Year.

           d.  Once distributions have begun to a 5% owner under this Section
               6.06(F)(6) they must continue to be distributed, even if the
               Participant ceases to be a 5% owner in a subsequent year.

        G.     TRANSITIONAL RULE

        1. Notwithstanding the other requirements of this Section 6.06 and
           subject to the requirements of Section 6.05, Joint and Survivor
           Annuity Requirements, distribution on behalf of any Employee,
           including a 5% owner, may be made in accordance with all of the
           following requirements (regardless of when such distribution
           commences):

                                       54
<PAGE>   60

           a.  The distribution by the Fund is one which would not have
               disqualified such Fund under Section 401(a)(9) of the Code as in
               effect prior to amendment by the Deficit Reduction Act of 1984.

           b.  The distribution is in accordance with a method of distribution
               designated by the Employee whose interest in the Fund is being
               distributed or, if the Employee is deceased, by a Beneficiary of
               such Employee.

           c.  Such designation was in writing, was signed by the Employee or
               the Beneficiary, and was made before January 1, 1984.

           d.  The Employee had accrued a benefit under the Plan as of December
               31, 1983.

           e.  The method of distribution designated by the Employee or the
               Beneficiary specifies the time at which distribution will
               commence, the period over which distributions will be made, and
               in the case of any distribution upon the Employee's death, the
               Beneficiaries of the Employee listed in order of priority.

        2. A distribution upon death will not be covered by this transitional
           rule unless the information in the designation contains the required
           information described above with respect to the distributions to be
           made upon the death of the Employee.

        3. For any distribution which commences before January 1, 1984, but
           continues after December 31, 1983, the Employee, or the Beneficiary,
           to whom such distribution is being made, will be presumed to have
           designated the method of distribution under which the distribution is
           being made if the method of distribution was specified in writing and
           the distribution satisfies the requirements in Sections 6.06(G)(1)(a)
           and (e).

        4. If a designation is revoked, any subsequent distribution must satisfy
           the requirements of Section 401(a)(9) of the Cede and the regulations
           thereunder. If a designation is revoked subsequent to the date
           distributions are required to begin, the Plan must distribute by the
           end of the calendar year following the calendar year in which the
           revocation occurs the total amount not yet distributed which would
           have been required to have been distributed to satisfy Section
           401(a)(9) of the Code and the regulations thereunder, but for the
           Section 242(1,)(2) election. For calendar years beginning after
           December 31, 1988, such distributions must meet the minimum
           distribution incidental benefit requirements in Section 1.401(a)(9)-2
           of the Income Tax Regulations. Any changes in the designation will be
           considered to be a revocation o~ the designation. However, the mere
           substitution or addition of another Beneficiary (one not named in the
           designation) under the designation will not be considered to be a
           revocation of the designation, so long as such substitution of
           addition does not alter the period over which distributions are to be
           made under the designation, directly or indirectly (for example, by
           altering the relevant measuring life). In the case in which an amount
           is transferred or rolled over from one plan to another plan, the
           rules in Q&A J-2 and Q&A J-3 shall apply.


                                       55

6.07    ANNUITY CONTRACTS

        Any annuity contract distributed under the Plan (if permitted or
        required by this Section 6) must be nontransferable. The terms of any
        annuity contract purchased and distributed by the Plan to a Participant
        or spouse shall comply with the requirements of the Plan.

6.08    LOANS TO PARTICIPANTS

        If the Adoption Agreement so indicates, a Participant may receive a loan
        from the Fund, subject to the following rules:

        A. Loans shall be made available to all Participants on a reasonably
           equivalent basis.

        B. Loans shall not be made available to Highly Compensated Employees (as
           defined in Section 414(q) of the Code) in an amount greater than the
           amount made available to other Employees.

        C. Loans must be adequately secured and bear a reasonable interest rate.

        D. No Participant loan shall exceed the present value of the Vested
           portion of a Participant's Individual Account.

        E. A Participant must obtain the consent of his or her spouse, if any,
           to the use of the Individual Account as security for the loan.
           Spousal consent shall be obtained no earlier than the beginning of
           the 90 day period that ends on the date on which the loan is to be so
           secured. The consent must be in writing, must acknowledge the effect
           of the loan, and must be witnessed by a plan representative or notary
           public. Such consent shall thereafter be binding with respect to the
           consenting spouse or any subsequent spouse with respect to that loan.
           A new consent shall be required if the account balance is used for
           renegotiation, extension, renewal, or other revision of the loan.

        F. In the event of default, foreclosure on the note and attachment of
           security will not occur until a distributable event occurs in the
           Plan.

        G. No loans will be made to any shareholder-employee or Owner-Employee.
           For purposes of this requirement, a shareholder-employee means an
           employee or officer of an electing small business (Subchapter S)
           corporation who owns (or is considered as owning within the meaning
           of Section 318(a)(1) of the Code), on any day during the taxable year
           of such corporation, more than 5% of the outstanding stock of the
           corporation.

        If a valid spousal consent has been obtained in accordance with 6.08(E),
        then, notwithstanding any other provisions of this Plan, the portion of
        the Participant's Vested Individual Account used as a security interest
        held by the Plan by reason of a loan outstanding to the Participant
        shall be taken into account for purposes of determining the 



                                       56
<PAGE>   62
        amount of the account balance payable at the time of death or
        distribution, but only if the reduction is used as repayment of the
        loan. If less than 1000/" of the Participant's Vested Individual
        Account (determined without regard to the preceding sentence) is
        payable to the surviving spouse, then the account balance shall be
        adjusted by first reducing the Vested Individual Account by the amount
        of the security used as repayment of the loan, and then determining
        the benefit payable to the surviving spouse.

        No loan to any Participant can be made to the extent that such loan when
        added to the outstanding balance of all other loans to the Participant
        would exceed the lesser of (a) $50,000 reduced by the excess (if any) of
        the highest outstanding balance of loans during the one year period
        ending on the day before the loan is made, over the outstanding balance
        of loans from the Plan on the date the loan is made, or (b) 50% of the
        present value of the nonforfeitable Individual Account of the
        Participant or, if greater, the total Individual Account up to $10,000.
        For the purpose of the above limitation, all loans from all plans of the
        Employer and other members of a group of employers described in Sections
        414(b), 414(c), and 414(m) of the Code are aggregated. Furthermore, any
        loan shall by its terms require that repayment (principal and interest)
        be amortized in level payments, not less frequently than quarterly, over
        a period not extending beyond 5 years from the date of the loan, unless
        such loan is used to acquire a dwelling unit which within a reasonable
        time (determined at the time the loan is made) will be used as the
        principal residence of the Participant. An assignment or pledge of any
        portion of the Participant's interest in the Plan and a loan, pledge, or
        assignment with respect to any insurance contract purchased under the
        Plan, will be treated as a loan under this paragraph.

        The Plan Administrator shall administer the loan program in accordance
        with a written document. Such written document shall include, at a
        minimum, the following: (i) the identity of the person or positions
        authorized to administer the Participant loan program; (ii) the
        procedure for applying for loans; (iii) the basis on which loans will be
        approved or denied; (iv) limitations (if any) on the types and amounts
        of loans offered; (v) the procedure under the program for determining a
        reasonable rate of interest; (vi) the types of collateral which may
        secure a Participant loan; and (vii) the events constituting default and
        the steps that will be taken to preserve Plan assets in the event of
        such default.

6.09    DISTRIBUTION IN KIND

        The Plan Administrator may cause any distribution under this Plan to be
        made either in a form actually held in the Fund, or in cash by
        converting assets other than cash into cash, or in any combination of
        the two foregoing ways.

6.10    DIRECT ROLLOVERS OF ELIGIBLE ROLLOVER DISTRIBUTIONS

        A. DIRECT ROLLOVER OPTION - This Section applies to distributions made
           on or after January 1, 1993. Notwithstanding any provision of the
           Plan to the contrary that would otherwise limit a distributee's
           election under this Section, a distributee may elect, at the time and
           in the manner prescribed by the Plan Administrator, to have any


                                       57
<PAGE>   63

           portion of an eligible rollover distribution paid directly to an
           eligible retirement plan specified by the distributee in a direct
           rollover.

        B. DEFINITIONS

           1.  Eligible rollover distribution - An eligible rollover
               distribution is any distribution of all or any portion of the
               balance to the credit of the distributee, except that an eligible
               rollover distribution does not include:

                  a.  any distribution that is one of a series of substantially
                      equal periodic payments (not less frequently than
                      annually) made for the life (or life expectancy) of the
                      distributee or the joint lives (or joint life
                      expectancies) of the distributee and the distributee's
                      designated beneficiary, or for a specified period of ten
                      years or more;

                  b.  any distribution to the extent such distribution is
                      required under Section 401(a)(9) of the Code; and

                  c.  the portion of any distribution that is not includible in
                      gross income (determined without regard to the exclusion
                      for net unrealized appreciation with respect to employer
                      securities).

          2.   Eligible retirement plan - An eligible retirement plan is an
               individual retirement account described in Section 408(a) of the
               Code, an individual retirement annuity described in Section 408~)
               of the Code, an annuity plan described in Section 403(a) of the
               Code, or a qualified trust described in Section 401 (a) of the
               Code, that accepts the distributee's eligible rollover
               distribution. However, in the case of an eligible rollover
               distribution to the surviving spouse, an eligible retirement plan
               is an individual retirement account or individual retirement
               annuity.

           3.  Distributee - A distributee includes an Employee or former
               Employee. In addition, the Employee's or former Employee's
               surviving spouse and the Employee's or former Employee's spouse
               or former spouse who is the alternate payee under a qualified
               domestic relations order, as defined in Section 414(p) of the
               Code, are distributees with regard to the interest of the spouse
               or former spouse.

           4.  Direct rollover - A direct rollover is a payment by the Plan to
               the eligible retirement plan specified by the distributee.

        Portion of the Participant's Individual Account shall file a written
        request with the Plan Administrator on a form to be furnished to him by
        the Plan Administrator for such purpose. The request shall set forth the
        basis of the claim. The Plan Administrator is authorized to conduct such
        examinations as may be necessary to facilitate the payment of any
        benefits to which the Participant or Beneficiary may be entitled under
        the terms of the Plan.

7.02    DENIAL OF CLAIM

        Whenever a claim for a Plan distribution by any Participant or
        Beneficiary has been wholly or partially denied, the Plan Administrator
        must furnish such Participant or Beneficiary written notice of the
        denial within 60 days of the date the original claim was filed. This
        notice shall set forth the specific reasons for the denial, specific
        reference to pertinent Plan provisions on which the denial is based, a
        description of any additional information or material needed to perfect
        the claim, an explanation of why such additional information or material
        is necessary and an explanation of the procedures for appeal.

7.03    REMEDIES AVAILABLE

        The Participant or Beneficiary shall have 60 days from receipt of the
        denial notice in which to make written application for review by the
        Plan Administrator. The Participant or Beneficiary may request that the
        review be in the nature of a hearing. The Participant or Beneficiary
        shall have the right to representation, to review pertinent documents
        and to submit comments in writing. The Plan Administrator shall issue a
        decision on such review within 60 days after receipt of an application
        for review as provided for in Section 7.02. Upon a decision unfavorable
        to the Participant or Beneficiary, such Participant or Beneficiary shall
        be entitled to bring such actions in law or equity as may be necessary
        or appropriate to protect or clarify his right to benefits under this
        Plan.

                                  SECTION EIGHT
                               PLAN ADMINISTRATOR

8.01    EMPLOYER IS PLAN ADMINISTRATOR

        A. The Employer shall be the Plan Administrator unless the managing body
           of the Employer designates a person or persons other than the
           Employer as the Plan Administrator and so notifies the Regional
           Prototype Sponsor and the Trustee (or Custodian, if applicable). The
           Employer shall also be the Plan Administrator if the person or
           persons so designated cease to be the Plan Administrator.

<PAGE>   65

        B. if the managing body of the Employer designates a person or persons
           other than the Employer as Plan Administrator, such person or persons
           shall serve at the pleasure of the Employer and shall serve pursuant
           to such procedures as such managing body may provide. Each such
           person shall be bonded as may be required by law.

8.02    POWERS AND DUTIES OF THE PLAN ADMINISTRATOR

        A. The Plan Administrator may, by appointment, allocate the duties of
           the Plan Administrator among several individuals or entities. Such
           appointments shall not be effective until the party designated
           accepts such appointment in writing.

        B. The Plan Administrator shall have the authority to control and manage
           the operation and administration of the Plan. The Plan Administrator
           shall administer the Plan for the exclusive benefit of the
           Participants and their Beneficiaries in accordance with the specific
           terms of the Plan.

               manner consistent with the Plan's documents and the Plan
               Administrator's construction or determination in good faith shall
               be conclusive and binding on all persons except as otherwise
               provided herein or by law. Any interpretation or construction
               shall be done in a nondiscriminatory manner and shall be
               consistent with the intent that the Plan shall continue to be
               deemed a qualified plan under the terms of Section 401(a) of the
               Code, as amended from time-to-time, and shall comply with the
               terms of ERISA, as amended from time-to-time;

           2.  To determine all questions relating to the eligibility of

               Trustee (or Custodian, if applicable) with respect to all
               disbursements under the Plan and when requested by the Trustee
               (or Custodian), to furnish the Trustee (or Custodian) with
               instructions, in writing on matters pertaining to the Plan and
               the Trustee (or Custodian) may rely and act thereon;

               Plan;

           7.  To furnish each Employee, Participant or Beneficiary such
               notices, information and reports under such circumstances as may

           appropriate to accomplish his duties under the Plan, including, but
           not limited to, the following:

           1.  To appoint and retain such persons as may be necessary to carry
               out the functions of the Plan Administrator;

           2.  To appoint and retain counsel, specialists or other persons as
               the Plan Administrator deems necessary or advisable in the
               administration of the Plan;

           3.  To resolve all questions of administration of the Plan;

           4.  To establish such uniform and nondiscriminatory rules which it

               deemed necessary or advisable to carry out the purpose of the
               Plan.

8.03    EXPENSES AND COMPENSATION

        All reasonable expenses of administration including, but not limited to,

        paid from the assets of the Fund. Alternatively, the Employer may, in
        its discretion, pay such expenses. The Employer shall furnish the Plan
        Administrator with such clerical and other assistance as the Plan
        Administrator may need in the performance of his duties.

8.04    INFORMATION FROM EMPLOYER

        To enable the Plan Administrator to perform his duties, the Employer
        shall supply full and timely information to the Plan Administrator (or
        his designated agents) on all matters relating to the Compensation of
        all Participants, their regular employment, retirement, death,
        Disability or Termination of Employment, and such other pertinent facts
        as the Plan Administrator (or his agents) may require. The Plan
        Administrator shall advise the Trustee (or Custodian, if applicable) of
        such of the foregoing facts as may be pertinent to the Trustee's (or
        Custodian's) duties under the Plan. The Plan Administrator (or his
        agents) is entitled to rely on such information as is supplied by the
        Employer and shall have no duty or responsibility to verify such
        information.

                                  SECTION NINE
                            AMENDMENT AND TERMINATION

9.01    RIGHT OF REGIONAL PROTOTYPE SPONSOR TO AMEND THE PLAN

        A. The Regional Prototype Sponsor may amend any part of the Plan.
           However, it shall be understood that the Regional Prototype Sponsor
           shall be under no obligation to amend the Plan documents and the
           Employer expressly waives any rights or claims against the Regional
           Prototype Sponsor for not exercising this power to amend.

        B. An amendment by the Regional Prototype Sponsor shall be accomplished
           by giving written notice to the Employer of the amendment to be made.
           The notice shall set forth the text of such amendment and the date
           such amendment is to be effective. Such amendment shall take effect
           unless within the 30 day period after such notice is provided, or
           within such shorter period as the notice may specify, the Employer
           gives the Regional Prototype Sponsor written notice of refusal to
           consent to the amendment. Such written notice of refusal shall have
           the effect of withdrawing the Plan as a regional prototype plan and
           shall cause the Plan to be considered an individually designed plan.
           The right of the Regional Prototype Sponsor to cause the Plan to be
           amended shall terminate should the Plan cease to conform as a
           regional prototype plan as provided in this or any other section.

9.02    RIGHT OF EMPLOYER TO AMEND THE PLAN

        The Employer may ~) change the choice of options in the Adoption
        Agreement, (2) add overriding language in the Adoption Agreement when
        such language is necessary to satisfy Section ~5 or Section ~6 of the
        Code because of the required aggregation of multiple plans, and (3) add
        certain model amendments published by the Internal Revenue Service which
        specifically provide that their adoption will not cause the Plan to be
        treated as individually designed. An Employer that amends the Plan for
        any other reason, including a waiver of the minimum funding requirement
        under Section 412(d) of the Code, will no longer participate in this
        regional prototype plan and will be considered to have an individually
        designed plan.

        An Employer who wishes to amend the Plan to change the options it has
        chosen in the Adoption Agreement must complete and deliver a new
        Adoption Agreement to the Regional Prototype Sponsor and Trustee (or
        Custodian, if applicable). Such amendment shall become effective upon
        execution by the Employer and Trustee (or Custodian).

        The Employer further reserves the right to replace the Plan in its
        entirety by adopting another retirement plan which the Employer
        designates as a replacement plan.

                                       62
<PAGE>   68

9.03    LIMITATION ON POWER TO AMEND

        No amendment to the Plan shall be effective to the extent that it has
        the effect of decreasing a Participant's accrued benefit.
        Notwithstanding the preceding sentence, a Participant's Individual
        Account may be reduced to the extent permitted under Section 412(c)(8)
        of the Code. For purposes of this paragraph, a plan amendment which has
        the effect of decreasing a Participant's Individual Account or
        eliminating an optional form of benefit with respect to benefits
        attributable to service before the amendment shall be treated as
        reducing an accrued benefit. Furthermore, if the vesting schedule of a
        Plan is amended, in the case of an Employee who is a Participant as of
        the later of the date such amendment is adopted or the date it becomes
        effective, the Vested percentage (determined as of such date) of such
        Employee's individual Account derived from Employer Contributions will
        not be less than the percentage computed under the Plan without regard
        to such amendment.

9.04    AMENDMENT OF VESTING SCHEDULE

        If the Plan's vesting schedule is amended, or the Plan is amended in any
        way that directly or indirectly affects the computation of the
        Participant's Vested percentage, or if the Plan is deemed amended by an
        automatic change to or from a top-heavy vesting schedule, each
        Participant with at least 3 Years of Vesting Service with the Employer
        may elect, within the time set forth below, to have the Vested
        percentage computed under the Plan without regard to such amendment.

        For Participants who do not have at least 1 Hour of Service in any Plan
        Year beginning after December 31, 1988, the preceding sentence shall be
        applied by substituting "5 Years of Vesting Service" for "3 Years of
        Vesting Service" where such language appears.

        The Period during which the election may be made shall commence with the
        date the amendment is adopted or deemed to be made and shall end the
        later of:

        A.     60 days after the amendment is adopted;

        B.     60 days after the amendment becomes effective; or

        C.     60 days after the Participant is issued written notice of the
               amendment by the Employer or Plan Administrator.

9.05    PERMANENCY

        The Employer expects to continue this Plan and make the necessary
        contributions thereto indefinitely, but such continuance and payment is
        not assumed as a contractual obligation. Neither the Adoption Agreement
        nor the Plan nor any amendment or modification thereof nor the making of
        contributions hereunder shall be construed as giving any Participant or
        any person whomsoever any legal or equitable right against the 

                                       63
<PAGE>   69

        Employer, the Trustee (or Custodian, if applicable), the Plan
        Administrator or the Regional Prototype Sponsor except as specifically
        provided herein, or as provided by law.

9.06    METHOD AND PROCEDURE FOR TERMINATION

        The Plan may be terminated by the Employer at any time by appropriate
        action of its managing body. Such termination shall be effective on the
        date specified by the Employer. The Plan shall terminate if the Employer
        shall be dissolved, terminated, or declared bankrupt. Written notice of
        the termination and effective date thereof shall be given to the Trustee
        (or Custodian, if applicable), Plan Administrator, Regional Prototype
        Sponsor, Participants and Beneficiaries of deceased Participants, and
        the required filings (such as the Form 5500 series and others) must be
        made with the Internal Revenue Service and any other regulatory body as
        required by current laws and regulations. Until all of the assets have
        been distributed from the Fund, the Employer must keep the Plan in
        compliance with current laws and regulations by (a) making appropriate
        amendments to the Plan and (b) taking such other measures as may be
        required.

9.07    CONTINUANCE OF PLAN BY SUCCESSOR EMPLOYER

        Notwithstanding the preceding Section 9.06, a successor of the Employer
        may continue the Plan and be substituted in the place of the present
        Employer. The successor and the present Employer (or, if deceased, the
        executor of the estate of a deceased Self-Employed Individual who was
        the Employer) must execute a written instrument authorizing such
        substitution and the successor must complete and sign a new Adoption
        Agreement.

9.08    FAILURE OF PLAN QUALIFICATION

        If the Plan fails to attain or retain its qualified status, the Plan
        will no longer be considered to be part of a regional prototype plan,
        and such Employer can no longer participate under this regional
        prototype. In such event, the Plan will be considered an individually
        designed plan.

                                   SECTION TEN
                                  MISCELLANEOUS

10.01   STATE COMMUNITY PROPERTY LAWS

        The terms and conditions of this Plan shall be applicable without regard
        to the community property laws of any state.

10.02   HEADINGS

        The headings of the Plan have been inserted for convenience of reference
        only and are to be ignored in any construction of the provisions hereof.

10.03   GENDER AND NUMBER

        Whenever any words are used herein in the masculine gender they shall be
        construed as though they were also used in the feminine gender in all
        cases where they would so apply, and whenever any words are used herein
        in the singular form they shall be construed as though they were also
        used in the plural form in all cases where they would so apply.

10.04   PLAN MERGER OR CONSOLIDATION

        In the case of any merger or consolidation of the Plan with, or transfer
        of assets or liabilities of such Plan to, any other plan, each
        Participant shall be entitled to receive benefits immediately after the
        merger, consolidation, or transfer (if the Plan had then terminated)
        which are equal to or greater than the benefits he would have been
        entitled to receive immediately before the merger, consolidation, or
        transfer (if the Plan had then terminated). The Trustee (or Custodian,
        if applicable) has the authority to enter into merger agreements or
        agreements to directly transfer the assets of this Plan but only if such
        agreements are made with trustees or custodians of other retirement
        plans described in Section 401(a) of the Code.

10.05   STANDARD OF FIDUCIARY CONDUCT

        The Employer, Plan Administrator, Trustee and any other fiduciary under
        this Plan shall discharge their duties with respect to this Plan solely
        in the interests of Participants and their Beneficiaries and with the
        care, skill, prudence and diligence under the circumstances then
        prevailing that a prudent man acting in like capacity and familiar with
        such matters would use in the conduct of an enterprise of a like
        character and with like aims. No fiduciary shall cause the Plan to
        engage in any transaction known as a "prohibited transaction" under
        ERISA.

10.06   GENERAL UNDERTAKING OF ALL PARTIES

        All parties to this Plan and all persons claiming any interest
        whatsoever hereunder agree to perform any and all acts and execute any

        carrying out of this Plan and any of the provisions.

10.07   AGREEMENT BINDS HEIRS, ETC.

        This Plan shall be binding upon the heirs, executors, administrators,
        successors and assigns, as those terms shall apply to any and all
        parties hereto, present and future.

10.08   DETERMINATION OF TOP-HEAVY STATUS

        A. For any Plan Year beginning after December 31, 1983, this Plan is a
           Top-Heavy Plan if any of the following conditions exist:

                                       65
<PAGE>   71

           1.  If the top-heavy ratio for this Plan exceeds 60% and this Plan is
               not part of any required aggregation group or permissive
               aggregation group of plans.

           2.  If this Plan is part of a required aggregation group of plans but
               not part of a permissive aggregation group and the top-heavy
               ratio for the group of plans exceeds 60%.

           3.  If this Plan is a part of a required aggregation group and part
               of a permissive aggregation group of plans and the top-heavy
               ratio for the permissive aggregation group exceeds 60%.

               For purposes of this Section 10.08, the following terms shall
               have the meanings indicated below:

        B. KEY EMPLOYEE - Any Employee or former Employee (and the beneficiaries
           of such Employee) who at any time during the determination period was
           an officer of the Employer if such individual's annual compensation
           exceeds 50% of the dollar limitation under Section 415(b)(1)(A) of
           the Code, an owner (or considered an owner under Section 318 of the
           Code) of one of the 10 largest interests in the Employer if such
           individual's compensation exceeds 100% of the dollar limitation under
           Section 415(c)(1)(A) of the Code, a 5% owner of the Employer, or a 1%
           owner of the Employer who has an annual compensation of more than
           $150,000. Annual compensation means compensation as defined in
           Section 415(c)(3) of the Code, but including amounts contributed by
           the Employer pursuant to a salary reduction agreement which are
           excludible from the Employee's gross income under Section 125,
           Section 402(a)(8), Section 402(h) or Section 403(b) of the Code. The
           determination period is the Plan Year containing the determination
           date and the 4 preceding Plan Years.

           The determination of who is a Key Employee will be made in accordance
           with Section 416(i)(1) of the Code and the regulations thereunder.

        C. TOP-HEAVY RATIO

        1. If the Employer maintains one or more defined contribution plans
           (including any simplified employee pension plan and the Employer has
           not maintained any defined benefit plan which during the 5-year
           period ending on the determination date(s) has or has had accrued
           benefits, the top-heavy ratio for this Plan alone or for the required
           or permissive aggregation group as appropriate is a fraction, the
           numerator of which is the sum of the account balances of all Key
           Employees as of the determination date(s) (including any part of any
           account balance distributed in the 5-year period ending on the
           determination date(s)), and the denominator of which is the sum of
           all account balances (including any part of any account balance
           distributed in the 5-year period ending on the determination
           date(s)), both computed in accordance with Section 416 of the Code
           and the regulations thereunder. Both the numerator and the
           denominator of the top-heavy ratio are increased to reflect any
           contribution not actually made as of 


                                       66
<PAGE>   72

           the determination date, but which is required to be taken into 
           account on that date under Section 416 of the Code and the 
           regulations thereunder.

        2. If the Employer maintains one or more defined contribution plans
           (including any simplified employee pension plan) and the Employer
           maintains or has maintained one or more defined benefit plans which
           during the 5-year period ending on the determination date(s) has or
           has had any accrued benefits, the top-heavy ratio for any required or
           permissive aggregation group as appropriate is a fraction, the
           numerator of which is the sum of account balances under the
           aggregated defined contribution plan or plans for all Key Employees,
           determined in accordance with (1) above, and the present value of
           accrued benefits under the aggregated defined benefit plan or plans
           for all Key Employees as of the determination date(s), and the
           denominator of which is the sum of the account balances under the
           aggregated defined contribution plan or plans for all Participants,
           determined in accordance with (1) above, and the present value of
           accrued benefits under the defined benefit plan or plans for all
           Participants as of the determination date(s), all determined in
           accordance with Section 416 of the Code and the regulations
           thereunder. The accrued benefits under a defined benefit plan in both
           the numerator and denominator of the top-heavy ratio are increased
           for any distribution of an accrued benefit made in the 5-year period
           ending on the determination date.

        3. For purposes of (1) and (2) above, the value of account balances and
           the present value of accrued benefits will be determined as of the
           most recent valuation date that falls within or ends with the
           12-month period ending on the determination date, except as provided
           in Section ~6 of the Code and the regulations thereunder for the
           first and second plan years of a defined benefit plan. The account
           balances and accrued benefits of a Participant (a) who is not a Key
           Employee but who was a Key Employee in a Prior Year, or (b) who has
           not been credited with at least one Hour of Service with any employer
           maintaining the plan at any time during the 5-year period ending on
           the determination date will be disregarded. The calculation of the
           top-heavy ratio, and the extent to which distributions, rollovers,
           and transfers are taken into account will be made in accordance with
           Section 416 of the Code and the regulations thereunder. Deductible
           employee contributions will not be taken into account for purposes of
           computing the top-heavy rat i(' When aggregating plans the value of
           account balances and accrued benefits will be calculated with
           reference to the determination dates that fall within the same
           calendar year.

           The accrued benefit of a Participant other than a Key Employee shall
           be determined under (a) the method if anything uniformly applies for
           accrual purposes under all defined benefit plans maintained by the
           Employer or (b) if there is no such method, as if such benefit
           accrued not more rapidly than the slowest accrual rate permitted
           under the fractional rule of Section 411(b)(1)(C) of the Code.

        4. Permissive aggregation group: The required aggregation group of plans
           plus any other plan or plans of the Employer which, when considered
           as a group with the required 



                                       67
<PAGE>   73

          aggregation group, would continue to satisfy the requirements of
          Sections 401(a)(4) and ~0 of the Code.

        5. Required aggregation group: (a) Each qualified plan of the Employer
           in which at least one Key Employee participates or participated at
           any time during the determination period (regardless of whether the
           Plan has terminated), and (b) any other qualified plan of the
           Employer which enables a plan described in (a) to meet the
           requirements of Sections 401(a)(4) or 410 of the Code.

        6. Determination date: For any Plan Year subsequent to the first Plan
           Year, the last day of the preceding Plan Year. For the first Plan
           Year of the Plan, the last day of that year.

        7. Valuation date: For purposes of calculating the top-heavy ratio, the
           valuation date shall be the last day of each Plan Year.

        8. Present value: For purposes of establishing the "present value" of
           benefits under a defined benefit plan to compute the top-heavy ratio,
           any benefit shall be discounted only for mortality and interest based
           on the interest rate and mortality table specified for this purpose
           in the defined benefit plan.

10.09   SPECIAL LIMITATIONS FOR OWNER-EMPLOYEES

        If this Plan provides contributions or benefits for one or more
        Owner-Employees who control both the business for which this Plan is
        established and one or more other trades or businesses, this Plan and
        the plan established for other trades or businesses must, when looked at
        as a single plan, satisfy Sections 401(a) and (d) of the Code for the
        employees of those trades or businesses.

        If the Plan provides contributions or benefits for one or more
        Owner-Employees who control one or more other trades or businesses, the
        employees of the other trades or businesses must be included in a plan
        which satisfies Sections 4~(a) and (d) of the Code and which provides
        contributions and benefits not less favorable than provided for
        Owner-Employees under this Plan.

        If an individual is covered as an Owner-Employee under the plans of two
        or more trades or businesses which are not controlled and the individual
        controls a trade or business, then the contributions or benefits of the
        employees under the plan of the trade or business which is controlled
        must be as favorable as those provided for him under the most favorable
        plan of the trade or business which is not controlled.

        For purposes of the preceding paragraphs, an Owner-Employee, or two or
        more Owner-Employees, will be considered to control a trade or business
        if the Owner-Employee, or two or more Owner-Employees, together:

        A.     own the entire interest in a unincorporated trade or business, or

                                       68
<PAGE>   74

        B. in the case of a partnership, own more than 50% of either the capital
           interest or the profit interest in the partnership.

        For purposes of the preceding sentence, an Owner-Employee, or two or
        more Owner-Employees, shall be treated as owning any interest in a
        partnership which is owned, directly or indirectly, by a partnership
        which such Owner-Employee, or such two or more Owner-Employees, are
        considered to control within the meaning of the preceding sentence.

10.10   INALIENABILITY OF BENEFITS

        No benefit or interest available hereunder will be subject to assignment
        or alienation, either voluntarily or involuntarily. The preceding
        sentence shall also apply to the creation, assignment, or recognition of
        a right to any benefit payable with respect to a Participant pursuant to
        a domestic relations order, unless such order is determined to be a
        qualified domestic relations order, as defined in Section 414(p) of the
        Code.

        Generally, a domestic relations order cannot be a qualified domestic
        relations order until January 1, 1985. However, in the case of a
        domestic relations order entered before such date, the Plan
        Administrator:

           (1) shall treat such order as a qualified domestic relations order if
               such Plan Administrator is paying benefits pursuant to such order
               on such date, and

           (2) may treat any other such order entered before such date as a
               qualified domestic relations order even if such order does not
               meet the requirements of Section ~4(p) of the Code.

                                 SECTION ELEVEN
                                401(K) PROVISIONS

        In addition to Sections 1 through 10, the provisions of this Section 11
        shall apply if the Employer has established a 401(k) cash or deferred
        arrangement (CODA) by completing and signing the appropriate Adoption
        Agreement.

11.100  DEFINITIONS

        The following words and phrases when used in the Plan with initial
        capital letters shall, for the purposes of this Plan, have the meanings
        set forth below unless the context indicates that other meanings are
        intended.

11.101  ACTUAL DEFERRAL PERCENTAGE (ADP)

        Means, for a specified group of Participants for a Plan Year, the
        average of the ratios (calculated separately for each Participant in
        such group) of ~) the amount of Employer Contributions actually paid
        over to the Fund on behalf of such Participant for the Plan Year to (2)
        the Participant's Compensation for such Plan Year (taking into account
        only 



                                       69
<PAGE>   75

        that Compensation paid to the Employee during the portion of the Plan
        Year he was an eligible Participant). For purposes of calculating the
        ADP, Employer Contributions on behalf of any Participant shall include:
        (1) any Elective Deferrals made pursuant to the Participant's deferral
        election, including Excess Elective Deferrals but excluding Elective
        Deferrals that are taken into account in the Average Contribution
        Percentage test (provided the ADP test is satisfied both with and
        without exclusion of these Elective Deferrals); (2) any Qualified
        Nonelective Contributions but excluding Qualified Nonelective
        Contributions that are taken into account in the Average Contribution
        Percentage test; and (3) at the election of the Employer, Qualified
        Matching Contributions. For purposes of computing Actual Deferral
        Percentages, an Employee who would be a Participant but for the failure
        to make Elective Deferrals shall be treated as a Participant on whose
        behalf no Elective Deferrals are made.

11.102  AGGREGATE LIMIT

        Means the sum of (1) 125% of the greater of the ADP of the Participants
        who are not Highly Compensated Employees for the Plan Year or the ACP of
        the Participants who are not Highly Compensated Employees under the Plan
        subject to the Code Section 401(m) for the Plan Year beginning with or
        within the Plan Year of the CODA and (2) the lesser of 200% or two plus
        the lesser of such ADP or ACP.

        pursuant to Section 11.201 and on whose behalf the Employer is
        contributing Elective Deferrals to the Plan.

11.105  CONTRIBUTION PERCENTAGE

        Means the ratio (expressed as a percentage) of the Participant's
        Contribution Percentage Amounts to the Participant's Compensation for

        entire Plan Year).

11.106  CONTRIBUTION PERCENTAGE AMOUNTS

        Means the sum of the Employee Contributions, Matching Contributions, and
        Qualified Matching Contributions (to the extent not taken into account
        for purposes of the ADP test) made under the Plan on behalf of the
        Participant for the Plan Year. Such Contribution Percentage Amounts
        shall not include Matching Contributions that are forfeited either to
        correct Excess Aggregate Contributions or because the contributions to
        which they relate are Excess Deferrals, Excess Contributions, or Excess
        Aggregate Contributions. If so elected in the Adoption Agreement, the
        Employer may include Qualified Nonelective Contributions in the
        Contribution Percentage Amounts. The 



                                       70
<PAGE>   76

        Employer also may elect to use Elective Deferrals in the Contribution
        Percentage Amounts so long as the ADP test is met before the Elective
        Deferrals are used in the ACP test and continues to be met following the
        exclusion of those Elective Deferrals that are used to meet the ACP
        test.

11.107  ELECTIVE DEFERRALS

        Means any Employer Contributions made to the Plan at the election of the
        Participant, in lieu of cash compensation, and shall include
        contributions made pursuant to a salary reduction agreement or other
        deferral mechanism. With respect to any taxable year, a Participant's
        Elective Deferral is the sum of all Employer contributions made on
        behalf of such Participant pursuant to an election to defer under any
        qualified CODA as described in Section 401(k) of the Code, any
        simplified employee pension cash or deferred arrangement as described in
        Section 402(h)(1)(B), any eligible deferred compensation plan under
        Section 457, any plan as described under Section 501(c)(18), and any
        Employer contributions made on the behalf of a Participant for the
        purchase of an annuity contract under Section 403(b) pursuant to a
        salary reduction agreement. Elective Deferrals shall not include any
        deferrals properly distributed as excess annual additions.

        No Participant shall be permitted to have Elective Deferrals made under
        this Plan, or any other qualified plan maintained by the Employer,
        during any taxable year, in excess of the dollar limitation contained in
        Section 402(g) of the Code in effect at the beginning of such taxable
        year.

        Elective Deferrals may not be taken into account for purposes of
        satisfying the minimum allocation requirement applicable to Top-Heavy
        Plans described in Section 3.01(E).

        Means any Employee who is eligible to make an Employee Contribution, or
        an Elective Deferral (if the Employer takes such contributions into
        account in the calculation of the Contribution Percentage), or to
        receive a Matching Contribution (including Forfeitures thereof) or a
        Qualified Matching Contribution. If an Employee Contribution is required
        as a condition of participation in the Plan, any Employee who would be a
        Participant in the Plan if such Employee made such a contribution shall
        be treated as an Eligible Participant on behalf of whom no Employee
        Contributions are made.

11.109  EMPLOYEE CONTRIBUTION

        A. The aggregate Contribution Percentage Amounts taken into account in
           computing the numerator of the Contribution Percentage actually made
           on behalf of Highly Compensated Employees for such Plan Year, over

        B. The maximum Contribution Percentage Amounts permitted by the ACP test
           (determined by reducing contributions made on behalf of Highly
           Compensated Employees in order of their Contribution Percentages
           beginning with the highest of such percentages).

        Such determination shall be made after first determining Excess Elective
        Deferrals pursuant to Section 11A12 and then determining Excess
        Contributions pursuant to Section 11.111.

11.111  EXCESS CONTRIBUTIONS

        Means, with respect to any Plan Year, the excess of:

        A. The aggregate amount of Employer Contributions actually taken into
           account in computing the ADP of Highly Compensated Employees for such
           Plan Year, over

        B. The maximum amount of such contributions permitted by the ADP test
           (determined by reducing contributions made on behalf of Highly
           Compensated Employees in order of the ADPs, beginning with the
           highest of such percentages).

11.112  EXCESS ELECTIVE DEFERRALS

        Means those Elective Deferrals that are includible in a Participant's
        gross income under Section 402(g) of the Code to the extent such
        Participant's Elective Deferrals for a taxable year exceed the dollar
        limitation under such Code section Excess Elective Deferrals shall be
        treated as annual additions under the Plan, unless such amounts are

        Matching Contributions may not be taken into account for purposes of
        satisfying the minimum allocation requirement applicable to Top-Heavy
        Plans described in Section ~

11.114  QUALIFIED NONELECTIVE CONTRIBUTIONS

        Means contributions (other than Matching Contributions or Qualified
        Matching Contributions) made by the Employer and allocated to

11.115  QUALIFIED MATCHING CONTRIBUTIONS

        Means Matching Contributions which are subject to the distribution and

11.200  CONTRIBUTING PARTICIPANT

11.201  REQUIREMENTS TO ENROLL AS A CONTRIBUTING PARTICIPANT

        A. Each Employee who becomes a Participant may enroll as a Contributing
           Participant. A Participant shall be eligible to enroll as a
           Contributing Participant on the Entry Date as of which he enters the

           Administrator shall permit in a uniform and nondiscriminatory manner,
           on any subsequent Entry Date. A Participant who wishes to enroll as a
           Contributing Participant must complete, sign and file a salary
           reduction agreement with the Plan Administrator.

        B. Notwithstanding the times set forth in Section 11.201(A) as of which
           a Participant may enroll as a Contributing Participant, the Plan
           Administrator shall have the authority to designate, in a
           nondiscriminatory manner, additional enrollment times during the 12
           month period beginning on the Effective Date in order that an orderly
           first enrollment might be completed. In addition, if the Employer has
           indicated in the Adoption Agreement that Elective Deferrals may be
           based on cash bonuses, then Participants shall be afforded a
           reasonable period of time prior to the issuance of such cash bonuses
           to elect to defer them into the Plan.

11.202  MODIFICATION OF SALARY REDUCTION AGREEMENT BY A CONTRIBUTING PARTICIPANT

        A Contributing Participant may modify his salary reduction agreement to
        increase or decrease (within the limits placed on Elective Deferrals in
        the Adoption Agreement) the amount of his Compensation deferred into the
        Plan. Such modification may only be made as of the first day of a Plan
        Year, or as of any other more frequent date(s) if the Plan Administrator
        permits in a uniform and nondiscriminatory manner. A Contributing
        Participant who desires to make such a modification shall complete, sign
        and file a new salary reduction agreement with the Plan Administrator at
        least thirty days before the modification is to become effective.

11.203  WITHDRAWAL AS A CONTRIBUTING PARTICIPANT

        A Participant may withdraw as a Contributing Participant as of the last
        day preceding any Entry Date (or as of any other date if the Plan
        Administrator so permits in a uniform and 



                                       73
<PAGE>   79

        nondiscriminatory manner) by revoking his authorization to the Employer
        to make Elective Deferrals on his behalf. A Participant who desires to
        withdraw as a Contributing Participant shall give written notice of
        withdrawal to the Plan Administrator at least thirty days (or such
        lesser period of days as the Plan Administrator shall permit in a
        uniform and nondiscriminatory manner) before the effective date of
        withdrawal. A Participant shall cease to be a Contributing Participant
        upon his Termination of Employment, or on account of termination of the
        Plan.

11.204  RETURN AS A CONTRIBUTING PARTICIPANT AFTER WITHDRAWAL

        A Participant who has withdrawn as a Contributing Participant under
        Section 11.203 may not again become a Contributing Participant until the
        first day of the first Plan Year following the effective date of his
        withdrawal as a Contributing Participant.

        Section 11.505 of the Plan, or Excess Aggregate Contributions as
        provided in Section 11.506 of the Plan, and to the extent elected by the
        Employer in the Adoption Agreement, the Employer may make Qualified
        Nonelective Contributions on behalf of Participants who are not Highly
        Compensated Employees that are sufficient to satisfy either the Actual
        Deferral Percentage test or the Average Contribution Percentage test, or
        both, pursuant to regulations under the Code.

11.303  QUALIFIED MATCHING CONTRIBUTIONS

        The Employer may elect to make Qualified Matching Contributions under
        the Plan on behalf of Participants as provided in the Adoption
        Agreement.

11.304  EMPLOYEE CONTRIBUTIONS

        Notwithstanding Section 3.02, if the Employer so allows in the Adoption
        Agreement, a Participant may contribute an Employee Contribution to the
        Plan.

        A separate account will be maintained by the Plan Administrator for the
        Employee Contributions for each Participant.

                                       74
<PAGE>   80

        A Participant may, upon a written request submitted to the Plan
        Administrator, withdraw the lesser of the portion of his Individual
        Account attributable to his Employee Contributions or the amount he
        contributed as Employee Contributions.

        Employee Contributions and earnings thereon will be nonforfeitable at
        all times. No Forfeiture will occur solely as a result an Employee's
        withdrawal of Employee Contributions.

11.400  NONDISCRIMINATION TESTING

11.401  ACTUAL DEFERRAL PERCENTAGE (ADP) TEST

        A. LIMITS ON HIGHLY COMPENSATED EMPLOYEES - The Actual Deferral
           Percentage (hereinafter "ADP") for Participants who are Highly
           Compensated Employees for each Plan Year and the ADP for Participants
           who are not Highly Compensated Employees for the same Plan Year must
           satisfy one of the following tests:

           1.   The ADP for Participants who are Highly Compensated Employees
                for the Plan Year shall not exceed the ADP for Participants who
                are not Highly Compensated Employees for the same Plan Year
                multiplied by 1.25; or

           2.   The ADP for Participants who are Highly Compensated Employees
                for the Plan Year shall not exceed the ADP for Participants who
                are not Highly Compensated Employees for the same Plan Year
                multiplied by 2.0 provided that the ADP for Participants who are
                Highly Compensated Employees does not exceed the ADP for
                Participants who are not Highly Compensated Employees by more
                than 2 percentage points.

        B. SPECIAL RULES

           1.   The ADP for any Participant who is a Highly Compensated Employee
                for the Plan Year and who is eligible to have Elective Deferrals
                (and Qualified Nonelective Contributions or Qualified Matching
                Contributions, or both, if treated as Elective Deferrals for
                purposes of the ADP test) allocated to his or her Individual
                Accounts under two or more arrangements described in Section
                401(k) of the Code, that are maintained by the Employer, shall
                be determined as if such Elective Deferrals (and, if applicable,
                such Qualified Nonelective Contributions or Qualified Matching
                Contributions, or both) were made under a single arrangement. If
                a Highly Compensated Employee participates in two or more cash
                or deferred arrangements that have different Plan Years, all
                cash or deferred arrangements ending with or within the same
                calendar year shall be treated as a single arrangement.

          2.    In the event that this Plan satisfies the requirements of
                Sections 401(k), 401(a)(4), or 410(b) of the Code only if
                aggregated with one or more other plans, or if one or more other
                plans satisfy the requirements of such sections of the Code only
                if 



                                       75
<PAGE>   81

                aggregated with this Plan, then this Section 11.401 shall be
                applied by determining the ADP of Employees as if all such plans
                were a single plan. For Plan Years beginning after December 31,
                1989, plans may be aggregated in order to satisfy Section 401(k)
                of the Code only if they have the same Plan Year.

          3.    For purposes of determining the ADP of a Participant who is a 5%
                owner or one of the 10 most highly paid Highly Compensated
                Employees, the Elective Deferrals (and Qualified Nonelective
                Contributions or Qualified Matching Contributions, or both, if
                treated as Elective Deferrals for purposes of the ADP test) and
                compensation of such Participant shall include the Elective
                Deferrals (and, if applicable, Qualified Nonelective
                Contributions and Qualified Matching Contributions, or both) and
                Compensation for the Plan Year of family members (as defined in
                Section 414(q)(6) of the Code). Family members, with respect to
                such Highly Compensated Employees, shall be disregarded as
                separate Employees in determining the ADP both for Participants
                who are not Highly Compensated Employees and for Participants
                who are Highly Compensated Employees.

          4.    For purposes of determining the ADP test, Elective Deferrals,
                Qualified Nonelective Contributions and Qualified Matching
                Contributions must be made before the last day of the 12 month
                period immediately following the Plan Year to which
                contributions relate.

          5.    The Employer shall maintain records sufficient to demonstrate
                satisfaction of the ADP test and the amount of Qualified
                Nonelective Contributions or Qualified Matching Contributions,
                or both, used in such test.

          6.    The determination and treatment of the ADP amounts of any
                Participant shall satisfy such other requirements as may be
                prescribed by the Secretary of the Treasury.

          7.    If the Employer has elected in the Adoption Agreement to take
                Qualified Matching Contributions into account as Elective
                Deferrals for purposes of the ADP test, then (subject to such
                other requirements as may be prescribed by the Secretary of the
                Treasury) only the amount of such Qualified Matching
                Contributions that are needed to meet the ADP test shall be
                taken into account.

          8.    In the event that the Plan Administrator determines that it is
                not likely that the ADP test will be satisfied for a particular
                Plan Year unless certain steps are taken prior to the end of
                such Plan Year, the Plan Administrator may require Contributing
                Participants who are Highly Compensated Employees to reduce
                their Elective Deferrals for such Plan Year in order to satisfy
                that requirement. Said reduction shall also be required by the
                Plan Administrator in the event that the Plan Administrator
                anticipates that the Employer will not be able to deduct all
                Employer Contributions from its income for Federal income tax
                purposes.

11.402  LIMITS ON EMPLOYEE CONTRIBUTIONS AND MATCHING CONTRIBUTIONS

        A. LIMITS ON HIGHLY COMPENSATED EMPLOYEES - The Average Contribution
           Percentage (hereinafter "ACP") for Participants who are Highly
           Compensated Employees for each Plan Year and the ACP for Participants
           who are not Highly Compensated Employees for the same Plan Year must
           satisfy one of the following tests:

           1.   The ACP for Participants who are Highly Compensated Employees
                for the Plan Year shall not exceed the ACP for Participants who
                are not Highly Compensated Employees for the same Plan Year
                multiplied by 1.25; or

           2.   The ACP for Participants who are Highly Compensated Employees
                for the Plan Year shall not exceed the ACP for Participants who
                are not Highly Compensated Employees for the same Plan Year
                multiplied by 2 provided that the ACP for the Participants who
                are Highly Compensated Employees does not exceed the ACP for
                Participants who are not Highly Compensated Employees by more
                than 2 percentage points.

        B. SPECIAL RULES

           1.   Multiple Use If one or more Highly Compensated Employees
                participate in both a CODA and a plan subject to the ACP test
                maintained by the Employer and the sum of the ADP and ACP of
                those Highly Compensated Employees subject to either or both
                tests exceeds the Aggregate Limit, then the ACP of those Highly
                Compensated Employees who also participate in a CODA will be
                reduced (beginning with such Highly Compensated Employee whose
                ACP is the highest) so that the limit is not exceeded. The
                amount by which each Highly Compensated Employee's Contribution
                Percentage Amounts is reduced shall be treated as an Excess
                Aggregate Contribution. The ADP and ACP of the Highly
                Compensated Employees are determined after any corrections
                required to meet the ADP and ACP tests. Multiple use does not
                occur if the ADP and ACP of the Highly Compensated Employees
                does not exceed 1.25 multiplied by the ADP and ACP of the
                Participants who are not Highly Compensated Employees.

          2.    For purposes of this Section 11A02, the Contribution Percentage
                for any Participant who is a Highly Compensated Employee and who
                is eligible to have Contribution Percentage Amounts allocated to
                his or her Individual Account under two or more plans described
                in Section 401(a) of the Code, or arrangements described in
                Section 401(k) of the Code that are maintained by the Employer,
                shall be determined as if the total of such Contribution
                Percentage Amounts was made under each plan. If a Highly
                Compensated Employee participates in two or more cash or
                deferred arrangements that have different plan years, all cash
                or deferred arrangements ending with or within the same calendar
                year shall be treated as a single arrangement.

                                       77
<PAGE>   83

          3.    In the event that this Plan satisfies the requirements of
                Sections 401(m), 401(a)(4) or 410~) of the Code only if
                aggregated with one or more other plans, or if one or more other
                plans satisfy the requirements of such Sections of the Code only
                if aggregated with this Plan, then this Section shall be applied
                by determining the Contribution Percentage of Employees as if
                all such plans were a single plan. For Plan Years beginning
                after December 31, 1989, plans may be aggregated in order to
                satisfy Section 401(m) of the Code only if they have the same
                Plan Year.

          4.    For purposes of determining the Contribution Percentage of a
                Participant who is a 5% owner or one of the 10 most highly pa id
                Highly Compensated Employees, the Contribution Percentage
                Amounts and Compensation of such Participant shall include the
                Contribution Percentage Amounts and Compensation for the Plan
                Year of family members, (as defined in Section 414(q)(6) of the
                Code). Family members, with respect to Highly Compensated
                Employees, shall be disregarded as separate Employees in
                determining the Contribution Percentage both for Participants
                who are not Highly Compensated Employees and for Participants
                who are Highly Compensated Employees.

          5.    For purposes of determining the Contribution Percentage test,
                Employee Contributions are considered to have been made in the
                Plan Year in which contributed to the Fund. Matching
                Contributions and Qualified Nonelective Contributions will be
                considered made for a Plan Year if made no later than the end of
                the 12 month period beginning on the day after the close of the
                Plan Year.

          6.    The Employer shall maintain records sufficient to demonstrate
                satisfaction of the ACP test and the amount of Qualified
                Nonelective Contributions or Qualified Matching Contributions,
                or both, used in such test.

          7.    The determination and treatment of the Contribution Percentage
                of any Participant shall satisfy such other requirements as may
                be prescribed by the Secretary of the Treasury.

          8.    If the Employer has elected in the Adoption Agreement to take
                Qualified Nonelective Contributions into account as Contribution
                Percentage Amounts for purposes of the ACP test, then (subject
                to such other requirements as may be prescribed by the Secretary
                of the Treasury) only the amount of such Qualified Nonelective
                Contributions that are needed to meet the ACP test shall be
                taken into account.

          9.    If the Employer has elected in the Adoption Agreement to take
                Elective Deferrals into account as Contribution Percentage
                Amounts for purposes of the ACP test, then (subject to such
                other requirements as may be prescribed by the Secretary of the
                Treasury) only the amount of such Elective Deferrals that are
                needed to meet the ACP test shall be taken into account.

11.500  DISTRIBUTION PROVISIONS

11.501  GENERAL RULE

        Distributions from the Plan are subject to the provisions of Section 6
        and the provisions of this Section 11. In the event of a conflict
        between the provisions of Section 6 and Section 11, the provisions of
        Section 11 shall control.

11.502  DISTRIBUTION REQUIREMENTS

        Elective Deferrals, Qualified Nonelective Contributions, and Qualified
        Matching Contributions, and income allocable to each are not
        distributable to a Participant or his or her Beneficiary or
        Beneficiaries, in accordance with such Participant's or Beneficiary or
        Beneficiaries' election, earlier than upon separation from service,
        death, or disability.

           409(d)(2) of the Code) used in a trade or business of such
           corporation if such corporation continues to maintain this Plan after
           the disposition, but only with respect to Employees who continue
           employment with the corporation acquiring such assets.

        C. The disposition by a corporation to an unrelated entity of such
           corporation's interest in a subsidiary (within the meaning of Section
           409(d)(3) of the Code) if such corporation continues to maintain this
           Plan, but only with respect to Employees who continue employment with
           such subsidiary.

        D. The attainment of age 59 1/2 in the case of a profit sharing plan.

        E. If the Employer has so elected in the Adoption Agreement, the

           All distributions that may be made pursuant to one or more of the
           foregoing distributable events are subject to the spousal and
           Participant consent requirements (if applicable) contained in
           Sections 401(a)(11) and 417 of the Code.

11.503  HARDSHIP DISTRIBUTION

        A. GENERAL - If the Employer has so elected in the Adoption Agreement,
           distribution of Elective Deferrals (and any earnings credited to a
           Participant's account as of the end of the last Plan Year ending
           before July 1, 1989) may be made to a Participant in the event of
           hardship. For the purposes of this Section, hardship is defined as
           an immediate and heavy financial need of the Employee where such
           Employee lacks 



                                       79
<PAGE>   85

                other available resources. Hardship distributions are subject to
                the spousal consent requirements contained in Sections
                401(a)(11) and 417 of the Code.

        B. SPECIAL RULES

          1.    The following are the only financial needs considered immediate
                and heavy: expenses incurred or necessary for medical care,
                described in Section 213(d) of the Code, of the Employee, the
                Employee's spouse or dependents; the purchase (excluding
                mortgage payments) of a principal residence for the Employee;
                payment of tuition and related educational fees for the next 12
                months of post-secondary education for the Employee, the
                Employee's spouse, children or dependents; or the need to
                prevent the eviction of the Employee from, or a foreclosure on
                the mortgage of, the Employee's principal residence.

          2.    A distribution will be considered as necessary to satisfy an
                immediate and heavy financial need of the Employee only if:

                  a.  The Employee has obtained all distributions, other than
                      hardship distributions, and all nontaxable loans under all
                      plans maintained by the Employer;

                  b.  All plans maintained by the Employer provide that the
                      Employee's Elective Deferrals (and Employee Contributions)
                      will be suspended for 12 months after the receipt of the
                      hardship distribution;

                  c.  The distribution is not in excess of the amount of an
                      immediate and heavy financial need (including amounts
                      necessary to pay any federal, state or local income taxes
                      or penalties reasonably anticipated to result from the
                      distribution); and

                  d.  All plans maintained by the Employer provide that the
                      Employee may not make Elective Deferrals for the
                      Employee's taxable year immediately following the taxable
                      year of the hardship distribution in excess of the
                      applicable limit under Section 402(g) of the Code for such
                      taxable year less the amount of such Employee's Elective
                      Deferrals for the taxable year of the hardship
                      distribution.

11.504  DISTRIBUTION OF EXCESS ELECTIVE DEFERRALS

        A. GENERAL RULE - A Participant may assign to this Plan any Excess
           Elective Deferrals made during a taxable year of the Participant by
           notifying the Plan Administrator on or before the date specified in
           the Adoption Agreement of the amount of the Excess Elective Deferrals
           to be assigned to the Plan. A Participant is deemed to notify the
           Plan Administrator of any Excess Elective Deferrals that arise by
           taking into account only those Elective Deferrals made to this Plan
           and any other plans of the Employer.

                                       80
<PAGE>   86

           Notwithstanding any other provision of the Plan, Excess Elective
           Deferrals, plus any income and minus any loss allocable thereto,
           shall be distributed no later than April 15 to any Participant to
           whose Individual Account Excess Elective Deferrals were assigned for
           the preceding year and who claims Excess Elective Deferrals for such
           taxable year

        B. DETERMINATION OF INCOME OR LOSS - Excess Elective Deferrals shall be
           adjusted for any income or loss up to the date of distribution. The
           income or loss allocable to Excess Elective Deferrals is the sum of:
           (1) income or loss allocable to the Participant's Elective Deferral
           account for the taxable year multiplied by a fraction, the numerator
           of which is such Participant's Excess Elective Deferrals for the year
           and the denominator is the Participant's Individual Account balance
           attributable to Elective Deferrals without regard to any income or
           loss occurring during such taxable year; and (2) 10% of the amount
           determined under (1) multiplied by the number of whole calendar
           months between the end of the Participant's taxable year and the date
           of distribution, counting the month of distribution if distribution
           occurs after the 15th of such month. Notwithstanding the preceding
           sentence, the Plan Administrator may compute the income or loss
           allocable to Excess Elective Deferrals in the manner described in
           Section 4 (i.e., the usual manner used by the Plan for allocating
           income or loss to Participants' Individual Accounts), provided such
           method is used consistently for all Participants and for all
           corrective distributions under the Plan for the Plan Year.

11.505  DISTRIBUTION OF EXCESS CONTRIBUTIONS

        A. GENERAL RULE - Notwithstanding any other provision of this Plan,
           Excess Contributions, plus any income and minus any loss allocable
           thereto, shall be distributed no later than the last day of each Plan
           Year to Participants to whose Individual Accounts such Excess
           Contributions were allocated for the preceding Plan Year. If such
           excess amounts are distributed more than 2 1/2 months after the last
           day of the Plan Year in which such excess amounts arose, a 10% excise
           tax will be imposed on the Employer maintaining the Plan with respect
           to such amounts. Such distributions shall be made to Highly
           Compensated Employees on the basis of the respective portions of the
           Excess Contributions attributable to each of such Employees. Excess
           Contributions of' Participants who are subject to the family member
           aggregation rules shall be allocated among the family members in
           proportion to the Elective Deferrals (and amounts treated as Elective
           Deferrals) of each family member that is combined to determine the
           combined ADP.

           Excess Contributions (including the amounts recharacterized) shall be
           treated as annual additions under the Plan.

        B. DETERMINATION OF INCOME OR LOSS - Excess Contributions shall be
           adjusted for any income or loss up to the date of distribution. The
           income or loss allocable to Excess Contributions is the sum of: (I)
           income or loss allocable to Participant's Elective 



                                       81
<PAGE>   87

           Deferral account (and, if applicable, the Qualified Nonelective
           Contribution account or the Qualified Matching Contributions account
           or both) for the Plan Year multiplied by a fraction, the numerator of
           which is such Participant's Excess Contributions for the year and the
           denominator is the Participant's Individual Account balance
           attributable to Elective Deferrals (and Qualified Nonelective
           Contributions or Qualified Matching Contributions, or if any of such
           contributions are included in the ADP test) without regard to any
           income or loss occurring during such Plan Year; and (2) 10% of the
           amount determined under (1) multiplied by the number of whole 
           calendar months between the end of the Plan Year and the date of 
           distribution, counting the month of distribution if distribution
           occurs after the 15th of such month. Notwithstanding the preceding
           sentence, the Plan Administrator may compute the income or loss
           allocable to Excess Contributions in the manner described in 
           Section 4 (i.e., the usual manner used by the Plan for allocating
           income or loss to Participants' Individual Accounts), provided such
           method is used consistently for all Participants and for all
           corrective distributions under the Plan for the Plan Year.

        C. ACCOUNTING FOR EXCESS CONTRIBUTIONS - Excess Contributions shall be
           distributed from the Participant's Elective Deferral account and
           Qualified Matching Contribution account (if applicable) in proportion
           to the Participant's Elective Deferrals and Qualified Matching
           Contributions (to the extent used in the ADP test) for the Plan Year.
           Excess Contributions shall be distributed from the Participant's
           Qualified Nonelective Contribution account only to the extent that
           such Excess Contributions exceed the balance in the Participant's
           Elective Deferral account and Qualified Matching Contribution
           account.

11.506  DISTRIBUTION OF EXCESS AGGREGATE CONTRIBUTIONS

        A. GENERAL RULE - Notwithstanding any other provision of this Plan,
           Excess Aggregate Contributions, plus any income and minus any loss
           allocable thereto, shall be forfeited, if forfeitable, or if not
           forfeitable, distributed no later than the last day of each Plan Year
           to Participants to whose accounts such Excess Aggregate Contributions
           were allocated for the preceding Plan Year. Excess Aggregate
           Contributions of Participants who are subject to the family member
           aggregation rules shall be allocated among the family members in
           proportion to the Employee and Matching Contributions (or amounts
           treated as Matching Contributions) of each family member that is
           combined to determine the combined ACP. If such Excess Aggregate
           Contributions are distributed more than 2 1/2 months after the last
           day of the Plan Year in which such excess amounts arose, a 10% excise
           tax will be imposed on the Employer maintaining the Plan with respect
           to those amounts.

           Excess Aggregate Contributions shall be treated as annual additions
           under the Plan.

        B. DETERMINATION OF INCOME OR LOSS - Excess Aggregate Contributions
           shall be adjusted for any income or loss up to the date of
           distribution. The income or loss allocable to Excess Aggregate
           Contributions is the sum of: (1) income or loss 



                                       82
<PAGE>   88

          allocable to the Participant's Employee Contribution account, Matching
          Contribution account (if any, and if all amounts therein are not used
          in the ADP test) and, if applicable, Qualified Nonelective
          Contribution account and Elective Deferral account for the Plan Year
          multiplied by a fraction, the numerator of which is such Participant's
          Excess Aggregate Contributions for the year and the denominator is the
          Participant's Individual Account balance(s) attributable to
          Contribution Percentage Amounts without regard to any income or loss
          occurring during such Plan Year; and (2) 10% of the amount determined
          under (1) multiplied by the number of whole calendar months between
          the end of the Plan Year and the date of distribution, counting the
          month of distribution if distribution occurs after the 15th of such
          month. Notwithstanding the preceding sentence, the Plan Administrator
          may compute the income or loss allocable to Excess Aggregate
          Contributions in the manner described in Section 4 (i.e., the usual
          manner used by the Plan for allocating income or loss to Participants'
          Individual Accounts), provided such method is used consistently for
          all Participants and for all corrective distributions under the Plan
          for the Plan Year.

     C.   FORFEITURES OF EXCESS AGGREGATE CONTRIBUTIONS - Forfeitures of Excess
          Aggregate Contributions may either be reallocated to the accounts of
          Contributing Participants who are not Highly Compensated Employees or
          applied to reduce Employer Contributions, as elected by the Employer
          in Section 5 of the Adoption Agreement.

     D.   ACCOUNTING FOR EXCESS AGGREGATE CONTRIBUTIONS - Excess Aggregate
          Contributions shall be forfeited, if forfeitable or distributed on a
          pro rata basis from the Participant's Employee Contribution account,
          Matching Contribution account, and Qualified Matching Contribution
          account (and, if applicable, the Participant's Qualified Nonelective
          Contribution account or Elective Deferral account, or both).

11.507  RECHARACTERIZATION

        A Participant may treat his or her Excess Contributions as an amount
        distributed to the Participant and then contributed by the Participant
        to the Plan. Recharacterized amounts will remain nonforfeitable and
        subject to the same distribution requirements as Elective Deferrals.
        Amounts may not be recharacterized by a Highly Compensated Employee to
        the extent that such amount in combination with other Employee
        Contributions made by that Employee would exceed any stated limit under
        the Plan on Employee Contributions.

        Recharacterization must occur no later than 2 1/2 months after the last
        day of the Plan Year in which such Excess Contributions arose and is
        deemed to occur no earlier than the date the last Highly Compensated
        Employee is informed in writing of the amount recharacterized and the
        consequences thereof. Recharacterized amounts will be taxable to the
        Participant for the Participant's tax year in which the Participant
        would have received them in cash.

11.508  DISTRIBUTION OF ELECTIVE DEFERRALS IF EXCESS ANNUAL ADDITIONS

        Notwithstanding any other provision of the Plan, a Participant's
        Elective Deferrals shall be distributed to him to the extent that the
        distribution will reduce an excess annual addition (as that term is
        described in Section 3.05 of the Plan).

11.600  VESTING

11.601  100% VESTING ON CERTAIN CONTRIBUTIONS

        The Participant's accrued benefit derived from Elective Deferrals,
        Qualified Nonelective Contributions, Employee Contributions, and
        Qualified Matching Contributions is nonforfeitable. Separate accounts
        for Elective Deferrals, Qualified Nonelective Contributions, Employee
        Contributions, Matching Contributions, and Qualified Matching
        Contributions will be maintained for each Participant. Each account will
        be credited with the applicable contributions and earnings thereon.

11.602  FORFEITURES AND VESTING OF MATCHING CONTRIBUTIONS

        Matching Contributions shall be Vested in accordance with the vesting
        schedule selected for Matching Contributions in the Adoption Agreement.
        In any event, Matching Contributions shall be fully Vested at Normal
        Retirement Age, upon the complete or partial termination of the profit
        sharing plan, or upon the complete discontinuance of Employer
        Contributions. Notwithstanding any other provision of the Plan, Matching
        Contributions or Qualified Matching Contributions may be forfeited if
        the contributions to which they relate are Excess Elective Deferrals,
        Excess Contributions or Excess Aggregate Contributions.

        Any forfeitures of Matching Contributions which (as indicated in the
        Adoption Agreement) are allocated to Participants' Accounts shall be
        made in accordance with Section 6.01(D).

                        Section 6.01(a).)

                        The Employer shall allocate Employer Contributions (and
                        Participant forfeitures) in the same ratio that each

                        Year.

                (2)(X)  Integrated Allocation Formula-Maximum Disparity. The
                        Employer will allocate the annual Employer Contributions
                        and participant forfeitures, if any, in the same ratio
                        that each Participant's Excess Compensation for the Plan
                        Year bears to the total Excess Compensation of all
                        Participants for the Plan Year. The allocation under
                        this paragraph, as a percentage of each Participant's

                        Table contained in Article XVII. If the Plan is
                        top-heavy, then step one and two of Article XVII must be
                        allocated before this allocation is made

                        The Employer will then allocate any remaining Employer
                        Contributions and Participant forfeitures, if any, in
                        the same ratio that each Participant's Compensation for
                        the Plan Year bears to the total Compensation of all
                        Participants for the Plan Year.

<PAGE>   20

                (c) Amounts realized from the sale, exchange or other

                (d) other amounts which received special tax benefits, or
contributions made by the employer (whether or not under a salary reduction
agreement) towards the purchase of an annuity contract described in section
403(b) of the Internal Revenue Code (whether or not the contributions are
actually excludable from the gross income of the Employee).

        For purposes of applying the limitations of this article, compensation
for a limitation year is the compensation actually paid or made available during
such limitation year.

        Notwithstanding the preceding sentence, compensation for a participant
in a defined contribution plan who is permanently and totally disabled (as
defined in section 22(e) (3) of the Internal Revenue Code) is the compensation
such participant would have received for the limitation year if the participant
had been paid at the rate of compensation paid immediately before becoming
permanently and totally disabled; such imputed compensation for the disabled
participant may be taken into account only if the participant is not a highly
compensated employee (as defined in section 414(q) of the Code) and
contributions made on behalf of such participant are nonforfeitable when made.

        For years beginning after December 31, 1988, the annual compensation of
each participant taken into account for determining all benefits provided under
the plan for any determination period shall not exceed $200,00.00. This
limitation shall be adjusted by the Secretary at the same time and in the same
manner as under section 415(d) of the Code, except that the dollar increase in
effect on January 1 of any calendar year is effective for years beginning in
such calendar year and the first adjustment to the $200,000.00 limitation is
effected on January 1, 1990. If the period for determining compensation used in
calculating an employee's allocation for a determination period is a short plan
year (i.e. shorter that 12 months), the annual compensation limit is an amount
equal to the otherwise applicable annual compensation limit multiplied by the
fraction, the numerator of which is the number of months in the short plan year,
and the denominator of which is 12.

        In determining the compensation of a participant for purposes of this
limitation, the rules of section 414(q) (6) of the Code shall apply, except in
applying such rules, the term "family" shall include only the spouse of the
participant and any lineal descendants of the participant who have not attained
age 19 before the close of the year. If, as a result of the application of such
rules the adjusted $200,000 limitation is exceeded, then (except for purposes of
determining the portion of compensation up to the integration level if this plan
provides for permitted disparity), the limitation shall be prorated among the
affected individuals in proportion to each individual's compensation as
determined under this section prior to the application of this limitation.

disability, will be unable to perform the duties of his customary position of
employment (or is unable to engage in any substantial gainful activity) for an
indefinite period which the Plan Administrator considers will be of long
continued duration.

        A Participant also is disabled if he incurs the permanent loss or loss
of use of a member or function of the body, or is permanently disfigured, and
incurs a Separation from Service. The Plan considers a Participant disabled on
the date the Plan Administrator determines the Participant satisfied the
definition of disability. A Participant must submit to a physical examination in
order to confirm disability. The Plan Administrator will apply the provisions of
this Section in a nondiscriminatory, consistent, and uniform manner.

        2.16

        "Earned Income" means a Self-Employed Individual's net earnings from
self-employment in the trade or business with respect to which the Plan is
established, for which personal services of the individual are a material
income-producing factor. Net earnings will be determined without regard to items
not included in gross income and the deductions allocable to such items. Net
earnings are reduced by contributions by the Employer to a qualified plan to the
extent deductible under Section 404 of the Code. Net earnings shall be
determined with regard to the deduction allowed to the employer by section
164(f) of the Code for taxable years beginning after December 31, 1989.

<PAGE>   25

                (3) each hour for which back pay, irrespective of mitigation of

                (c) Solely for purposes of determining whether an Employee
incurs a Break in Service, an Employee who is absent from work for maternity or

for maternity or paternity reasons means an absence (1) by reason of the
pregnancy of the Employee, (2) by reason of a birth of a child of the Employee,
(3) by reason of the placement of a child with the Employee in connection with
the adoption of such child by such Employee, or (4) for purposes of caring for

The Hours of Service credited under this Subsection

                (c) shall be credited (1) in the Plan Year in which the absence
begins if the crediting is necessary to prevent a Break in Service in that
period, or (2) in all other cases, in the following Plan Year.

        2.25

        "Inactive Participant" shall mean any Employee or former Employee who
has ceased to be a Participant and on whose behalf an account is maintained
under the plan.

        2.26

        "Insurer" means the life insurance company chosen by the Trustee(s) to
issue policies to the Plan.

        2.27

        "Key Employee" means any Employee or former Employee (and the
Beneficiaries of such Employee) who at any time during the "Determination
Period" was an officer of the Employer if such individual's Compensation exceeds
50 percent of the dollar limitation under Section 415(b) (1) (A) of the Code, an
owner (or considered an owner under Section 318 of the Code) of one of the ten
largest interests in the Employer if such individual's compensation exceeds 100
percent of the dollar limitation under Section 415(c)(l)(A) of the Code, a
5-percent owner of the Employer, or a one percent owner of the Employer who has
an annual compensation of more than $150,000. Annual compensation means
compensation as defined in section 415(c) (3) of the Code, but including amounts
contributed by the employer pursuant to a salary reduction agreement which are

                                       22
<PAGE>   26

section 125, section 402(a)(8), section 402(h) or section 403(b) of the Code.
For purposes of determining a 5-percent owner or a one percent owner, neither
the aggregation rules nor the rules of subsection (b), (c), and (m) of IRC
Section 414 apply. Beneficiaries of an employee acquire the character of the
employee who performed service for the employer. Also, inherited benefits will
retain the character of the benefits of the employee who performed services for
the employer. For purposes of this Section, the "Determination Period" is the
Plan Year containing the Determination Date and the 4 preceding Plan Years. The
determination of who is a Key Employee will be made in accordance with Section
416(i) (1) of the Code and the regulations thereunder

        2.28

        "Leased Employees" The plan treats a Leased Employee as an employee of
the Employer. A Leased Employee is an individual (who otherwise is not an
Employee of the Employer) who, pursuant to a leasing agreement between the
Employer and any other person, has performed services for the Employer (or for
the Employer and any persons related to the Employer within the meaning of Code
Section 414(n)(6)) on a substantially full time basis for at least one year and
who performs services historically performed by employees in the Employer's
business field. If a Leased Employee is treated as an Employee, "Compensation"
includes compensation from the leasing organization which is attributable to
services performed for the Employer. The Plan does not treat a Leased Employee
as an Employee if the leasing organization covers the employee in a safe harbor
plan and, prior to application of this safe harbor plan exception, 20% or less
of the Employer's Employees (other than Highly Compensated Employees) are Leased
Employees. A safe harbor plan is a money purchase pension plan providing
immediate participation, full and immediate vesting, and a nonintegrated
contribution formula equal to at least 10% of the employee's compensation
without regard to employment by the leasing organization on a specified date.
The safe harbor plan must determine the 10% contribution on the basis of
compensation as defined in Code Section 415(c) (3) plus any employer
contribution under a qualified cash or deferred arrangement to the extent not
included in gross income under Section 402(a)(8) or 402(h)(l)(B), any amount
which the Employee would have received in cash but for an election under a
cafeteria plan (within the meaning of Section 125 of the Code), and any amount
contributed to an annuity contract described in Section 403(b) pursuant to a
salary reduction agreement (within the meaning of section 3121(a) (5) (D) of the
Code). Contributions or benefits provided a leased employee by the leasing
organization which are attributable to services performed for the recipient
employer shall be treated as provided by the recipient Employer.

        2.29

        "Matching Contribution" shall mean any contribution to the Plan made by
the Employer for the Plan Year and allocated to a Participant's account by
reason of the Participant's Employee Contributions or Elective Deferrals.
Matching contributions are not available for hardship withdrawals.

                    ARTICLE III -- PARTICIPATION AND VESTING

        3.01
        Participation

                (a) Covered Employees who, as of the first day of the Plan Year
in which this Plan is adopted, have completed the minimum age requirement and
have completed the minimum service requirement specified in Article I Section
6(A)2 and 6(A)3 shall become participants as of such date.

                (b) Covered Employees who do not become Participants under
Article III 3.01(a) shall become Participants on the Effective Date of
Participation specified in the Adoption Agreement following the date they
satisfy the age and service requirement specified in Article I Section 6(A)2 and
6(A)3.

                (c) Participants shall cease to be Participants as of the date
of termination of employment.

        3.02
        Election not to Participate

        If elected in writing by the Participant and his spouse, any Key
Employee may, by informing the Trustees, elect not to participate in the Plan.

        3.03
        Vesting

                (a) Notwithstanding the selection made in the Adoption Agreement
a Participant shall be fully (100%) vested in the balance of his Employer
Contribution Account upon his Normal Retirement Age, as defined in IRC Section
4"(a) (8), or if he has a Termination of Employment on account of his death.

                (b) (1) If a former Participant becomes a Participant after
having five (5) consecutive one-year Breaks in Service, Years of Service
completed by the Participant after such Breaks in Service shall be disregarded
for determining the vested interest in that portion of the Employer Contribution
Account balance which accrued before the Break in Service. However, all Years of
Service including those completed prior to such Breaks in Service will count for
determining the vested interest in that portion of the Employer Contribution
Account which accrued after such Breaks in Service.

                        (2) If a Participant does not incur five (5) consecutive
one-year Breaks in Service, all Years of Service shall be counted for
determining the vested interest in the Employer Contribution Account which
accrued before and after the Break in Service. A participant who is re-employed
after a break-in-service will be allowed to participate in the plan immediately
on his or her re-employment commencement date. In any event, a Participant's
Employer Contribution Account will continue to share in earnings and losses of
the Trust Fund.



                                       27
<PAGE>   31

                (3) In the case of a participants who does not have any
nonforfeitable right to the account balance derived from employer contributions,
years of service before a period of consecutive 1-year breaks in service will
not be taken into account in computing eligibility service if the number of
consecutive 1-year breaks in service in such period equals or exceeds the
greater of 5 or the aggregate number of years of service. Such aggregate number
of years of service will not include any years of service disregarded under the
preceding sentence by reason of prior breaks in service.

        If a participant's years of service are disregarded pursuant to the
preceding paragraph, such participant will be treated as a new employee for
eligibility purposes. If a participant's years of service may not be disregarded
pursuant to the preceding paragraph, such participant shall continue to
participate immediately upon reemployment.

                (4) In the case of any participant who has a 1-year break in
service, years of eligibility service before such break will not be taken into
account until the employee has completed a year of service after returning to
employment. Such year of service will be measured by the 12-consecutive month
period beginning on an employee's reemployment commencement date and, if
necessary, subsequent 12-consecutive month periods beginning on anniversaries of
reemployment commencement date. The reemployment commencement date is the first
day on which the employee is credited with an hour of service for the
performance of duties after the first eligibility computation period in which
the employee incurs a one year break in service.

                (5) In the event a participant is no longer a member of an
eligible class of employees and becomes ineligible to participate but has not
incurred a break in service, such employee will participate immediately upon
returning to an eligible class of employees. If such participant incurs a break
in service, eligibility will be determined under the break in service rules of
the plan. In the event an employee who is not a member of an eligible class of
employees becomes a member of an eligible class, such employee will participate
immediately if such employee has satisfied the minimum age and service
requirements and would have otherwise previously become a participant.

                (6) If an employee terminates service, and elects, in accordance
with the requirements of Article VIII, to receive the value of the employee's
vested account balance, the nonvested portion will be treated as a forfeiture.
If the employee elects to have distributed less than the entire vested portion
of the account balance derived from employer contributions, the part of the
nonvested portion that will be treated as a forfeiture is the total nonvested
portion multiplied by a fraction, the numerator of which is the amount of the
distribution attributable to employer contributions and the dominator of which
is the total value of the vested employer derived account balance. If an
employee receives a distribution pursuant to this section and the employee
resumes employment covered under this plan, the employee's employer-derived
account balance will be restored to the amount on the date of distribution if
the employee repays to the plan the full amount of the distribution attributable
to employer contributions before the earlier of 5 years after the first date on
which the participant is subsequently re-employed by the employer, or the date
the participant incurs 5 consecutive 1-year breaks in service following the 



                                       28
<PAGE>   32

date of the distribution. If an employee is deemed to receive a distribution
pursuant to this section, and the employee resumes employment covered under this
plan before the date the participant incurs 5 consecutive 1-year breaks in
service, upon the reemployment of such employee, the employer-derived account
balance of the employee will be restored to the amount on the date of such
deemed distribution. If a distribution is made at a time when a participant has
a nonforfeitable right to less than 100 percent of the account balance derived
from employer contributions and the participant may increase the nonforfeitable
percentage in the account;

                        (i)     A separate account will be established for the
                                participant's interest in the plan as of the
                                time of the distribution, and

                        (ii)    At any relevant time the participant's
                                nonforfeitable portion of the separate account
                                will be equal to an amount ("X") determined by
                                the formula:

                                            X=P(AB + (R x D)) - (R x D)

                                For the purposes of applying the formula: P is
                                the nonforfeitable percentage at the relevant
                                time, AB is the account balance at the relevant
                                time, D is the amount of the distribution, and R
                                is the ratio of the account balance at the
                                relevant time to the account balance after
                                distribution.

                (7) In the case of a participant who has 5 or more consecutive
1-year breaks in service, the participant's pre-break service will count in
vesting of the employer-derived accrued benefit only if either:

                        (i)     such participant has any nonforfeitable interest
                                in the account balance attributable to employer
                                contributions at the time of separation from
                                service; or

                        (ii)    upon returning to service the number of
                                consecutive 1-year breaks in service is less
                                than the number of years of service.

                (8) In the case of a participant who has 5 or more consecutive
1-year breaks in service all service after such breaks in service will be
disregarded for the purpose of vesting the employer-derived account balance that
accrued before such breaks in service. Such participant's pre-break service will
count in vesting the post-break employer-derived account balance only if either:

                        (i)     such participant has any nonforfeitable interest
                                in the account balance attributable to employer
                                contributions at the time of separation from
                                service; or

                        (ii)    upon returning to service the number of
                                consecutive 1-year breaks in service is less
                                than the number of years of service.



                                       29
<PAGE>   33

                                Separate accounts will be maintained for the
                                participant's pre-break and post-break
                                employer-derived account balance. Both accounts
                                will share in the earnings and losses of the
                                fund.

                (c) If the Plan's vesting schedule is amended, or the Plan is
amended in any way that directly or indirectly affects the computation of the
Participant's vested percentage or if the Plan is deemed amended by an automatic
change to or from a top-heavy vesting schedule, each Participant with at least
three (3) years of Service with the Employer may elect, within a reasonable
period after the adoption of the amendment or change, to have the vested
percentage computed under the Plan without regard to such amendment or change.
Any participant whose non forfeitable percentage is determined under the new
vesting schedule may elect to have his non forfeitable percentage determined
under the old vesting schedule. The period during which the election may be made
shall commence with the date the amendment is adopted or deemed to be made and
shall end on the latest of:

                        (1) 60 days after the amendment is adopted;

                        (2) 60 days after the amendment becomes effective, or;

                        (3) 60 days after the Participant is issued written
notice of the amendment by the Employer or plan administrator.

                (d) No amendment to the Plan shall be effective to the extent
that it has the effect of decreasing a Participant's Account balance.
Notwithstanding the preceding sentence, a Participant's Account balance may be
reduced to the extent permitted under Section 412(c) (8)of the Code. For
purposes of this paragraph, a plan amendment which has the effect of decreasing
a participant's account balance or eliminating an optional form of benefit, with
respect to benefits attributable to service before the amendment shall be
treated as reducing an account balance. Furthermore, no amendment to the Plan
shall have the effect of decreasing a Participant's vested interest or accrued
benefit determined without regard to such amendment, as of the later of (1) the
date such amendment is adopted, or (2) the date it becomes effective.
Furthermore, if the vesting schedule of a plan is amended, in the case of an
employee who is a participant as of the later of the date such amendment is
adopted or the date it becomes effective, the nonforfeitable percentage
(determined as of such date) of such employee's right to his employer derived
accrued benefit will not be less than his percentage computed under the plan
without regard to such amendment.

        3.04
        Controlled Trades or Businesses

                (a) If this Plan provides contributions or benefits for one or
more Owner-Employees who control both the business for which this Plan is
established and one or more other trades or businesses, this Plan and the plan
established for other trades or businesses must, when looked at as a single
plan, satisfy Section 401(a) and (d) of the Code for the Employees of this and
all such other trades or businesses.



                                       30
<PAGE>   34

                (b) (1)If this Plan provides contributions or benefits for one
or more Owner-Employees who control one of more other trades or businesses, the
employees of such other trades or businesses must be included in a plan which
satisfies Section 401(a) and (d) of the Code and which provides contributions
and benefits not less favorable than those provided for Owner-Employees under
this Plan.

                (2) If an individual is covered as an Owner-Employee under the
plans of two or more trades or businesses which are not controlled and the
individual controls another trade or business, then the contributions or
benefits of the employees under the plan of the trades or businesses which are
controlled must be as favorable as those provided for him under the most
favorable plan of the trade or business which is not controlled.

                (c) For purposes of this Section 3.04, an Owner-Employee, or two
or more Owner-Employees, will be considered to control a trade or business if
the Owner-Employee, or two or more Owner-Employees together:

                        (1) Own the entire interest in a unincorporated trade or
business, or

                        (2) in the case of a partnership, own more than 50
percent of either the capital interest or the profits interest in the
partnership.

An Owner-Employee, or two or more Owner-Employees shall also be treated as
owning any interest in a partnership which is owned, directly or indirectly, by
a partnership which such Owner-Employee, or such two or more Owner-Employees,
are considered to control within the meaning of the preceding sentence.

        3.05
        Ineligible Class

        An employee who would otherwise be eligible to participate in this Plan
who is in an ineligible class of employees, will immediately participate in this
plan on becoming a member of an eligible class.

                    ARTICLE IV -- EMPLOYER CONTRIBUTIONS AND
                 VOLUNTARY NON-DEDUCTIBLE EMPLOYEE CONTRIBUTIONS

        4.01
        Employer Contributions to the Profit Sharing Plan

        If the Profit-Sharing Plan Adoption Agreement is completed in
conjunction with this Basic Plan Document, the Employer's contribution for each
Plan Year shall be the amount specified in the Adoption Agreement or such other
amount as may be specified in an appropriate resolution or other written
directive. No contribution shall be made for any Participant which would cause
the "Annual Addition" to any Participant's Account to exceed the "Maximum
Permissible Amount" specified in Article VI.

        4.02
        Timing of Employer Contributions

        (a) Employer contributions may be made in one or more installments at
such time or times during the Plan Year or during any additional period provided
by law for making contributions for the Plan year as the Employer may decide.

        (b) For purposes of making allocations to Employer contribution
Accounts, all contributions for any Plan Year shall be considered made on the
Allocation Date, regardless of the actual date of contribution.

        (c) All contributions shall be payable to the Trustees, except that with
the consent of the Trustees, the portion of the Employer's contribution which
represents premiums or considerations on insurance policies or annuity contracts
may be paid directly by the Employer to the Insurer under such terms as may be
mutually agreed upon by the Employer and Insurer.

        (d) A matching contribution shall be allocated to an employee's account
under the terms of the Plan as of any date within the plan year when it is
actually paid to the trust no later than the end of the twelve month period
beginning on the day after the close of such plan year, and is made on behalf of
an employee on account of such employee's elective contribution or employee
contributions for the plan year.

        4.03
        Establishing Employer Contribution Accounts

        (a) The Trustees shall establish a separate Employer Contribution
Account for each Participant for each Adoption Agreement completed in connection
with this Basic Plan Document. A Participant's share of Employer contributions,
forfeitures and mandatory Employee contributions determined in accordance with
Sections 6.01 and 6.02 shall be allocated to each such Account. Except as
provided in Subsection (b), all Participants' Employer Contribution Accounts
shall be held as a single, commingled fund except for life insurance and
individual annuity contracts.



                                       32
<PAGE>   36

        These shall be held exclusively for the benefit of the Participant upon
whose life such contract is issued.

        (b) The Trustees may, by mutual agreement with a Participant, segregate
such Participant's Account(s) and hold, invest and value such Account(s)
separately from all other Plan assets. After a Participant has a Termination of
Employment, the Trustees do not need the Participant's consent to establish a
segregated Account from which a distribution will be made to the Participant or
his Beneficiary, but all distributions must comply with Article VIII.

        4.04
        Voluntary Contributions

        (a) Each Participant may, if the Plan Administrator so allows, make
voluntary non-deductible contributions to the Plan at such times and under such
conditions as the Trustees may prescribe. However, Employer contributions and
voluntary contributions may not be commingled in the same individual annuity
contract.

        (b) The aggregate voluntary contributions during any Plan Year may not
exceed ten percent (10%) of a Participants aggregate Compensation during any
Plan Year.

        (c) Voluntary Contributions and Matching Contributions shall be
aggregated to determine if this Plan meets the nondiscrimination tests of Code
Section 401(m) and Proposed Treasury Regulations l.401(m)-l. Voluntary
Contributions shall, notwithstanding any other provision of this Plan, be
distributed first and then Matching Contributions to any highly compensated
participant if this Plan or any other Plan required to be aggregated with this
Plan for purposes of the nondiscrimination tests, if this Plan or the aggregated
plans fail the nondiscrimination tests. Under this test, the actual contribution
percentage (ACP) for the group of eligible highly compensated employees may not
exceed the greater of (a) 125% of the ACP for all other eligible employees or
(b) the lesser of twice the ACP for all other eligible employees, or such ACP
for all other eligible employees plus 2%. The ACP for a group of eligible
employees is the average of the ratios (calculated separately for each employee)
of the amount of voluntary and matching contributions (and any other
contributions required to be aggregated for purposes of the ACP test) made on
behalf of each employee for the plan year, divided by the employee's
compensation.

        4.05
        Payment of Voluntary Contributions

        (a) All voluntary contributions must be made in cash.

        (b) All voluntary contributions made under Section 4.04 shall be part of
the Trust Fund.

        (c) Voluntary contributions may not be used to purchase life insurance
contracts, but may be used, to the extent necessary, to keep any life insurance
contract which was initially



                                       33
<PAGE>   37

purchased with Employer contributions in force when Employer contributions are
insufficient for this purpose.

        (d) In the event voluntary contributions are used in the manner
described in Subsection (c) , the value of the life insurance contract which is
attributable to voluntary contributions shall be determined in the same ratio to
the total value of the contract as the premiums paid by voluntary contributions
bear to the total premiums paid.

        4.06
        Voluntary Contribution Account

        (a) The Trustees shall establish and maintain a Voluntary Contribution
Account for each Participant who makes voluntary contributions.

        (b) The balance in each Participant's Voluntary Contribution Account
shall at all times be fully (100%) vested. At no time shall the balance in a
Participant's Voluntary Contribution Account be forfeited for any reason.

        4.07
        Withdrawal of Voluntary Contributions

        (a) A Participant may, at any time, with spousal consent if married,
elect to withdraw all or any portion of the balance in his Voluntary
Contribution Account.

        (b) Upon a Termination of Employment, the balance in a Participant's
Voluntary Contribution Account shall be distributed to him at the time and in
the manner specified in Article VIII. However, a Participant may, with the
consent of the Trustees and his spouse choose a different method of distribution
for the Voluntary Contribution Account than is chosen for the Employer
Contribution Account.

        4.08
        Roll-overs

        A Participant may, with the consent of the Trustees, roll over to this
Plan all or any part of a qualified total distribution as defined in Section 402
(a) (5) (E) of the Code. An amount may also be transferred to this Plan on a
Participant's behalf directly from another plan which qualifies under Section
401(a) of the Code. In the event that a Participant makes a roll-over or if an
amount is transferred to this Plan on his behalf, the proceeds shall be held in
a segregated roll-over contribution account to be established by the Trustees
which shall be invested and valued separately from all other Plan assets. A
Participant shall at all times be fully (100%) vested in the value, if any, of
his roll-over contribution account.

        4.09
        Valuation of Trust Fund



                                       34
<PAGE>   38

        (a) The value of the Trust Fund and each Participant's Account shall be
determined as of the last day of the Plan Year or more frequently as determined
by the Administrative Committee. All assets of the Trust Fund shall be valued at
their fair market value, determined in accordance with regulations adopted by
the Trustees. On such date, the earnings and losses of the Trust Fund will be
allocated to each Participant's Account in the ratio that such Account balance
bears to all Account balances or based upon earning and losses in that Account.

        (b) The value of any life insurance or annuity contract held in a
Participant's Account as of the last day of the Plan Year shall be equal to the
sum of the net cash values of the life insurance contracts and the value
available to provide annuity benefits of allocated annuity contracts held in
such Account as of such date.

                         ARTICLE V -- ELECTIVE DEFERRALS

        5.01
        Maximum Amount of Elective Deferrals

        Effective as of January 1, 1987, no Employee shall be permitted to have
Elective Deferrals made under this plan during any calendar year in excess of
$7000.00 multiplied by the Adjustment Factor as provided by the Secretary of the
Treasury. The foregoing limit shall not apply to Elective Deferrals of amounts
attributable to service performed in 1986 and described in Section 1105(c) (5)
of the Tax Reform Act of 1986.

        5.02
        Employee Elections

        Each Participant shall file a written election form with the Plan
Administrator no later than the date he becomes eligible to participate,
specifying the portion of his Compensation to be contributed to the Plan as an
Elective Deferral. The portion contributed shall be deposited to the
Participants "Tax Sheltered Savings Account". Such election of the Participants
shall remain in effect until a new election is filed with the Plan Administrator
in accordance with Section 5.04.

        5.03
        Tax Sheltered Savings Account

        (a) The Trustees shall establish and maintain a Tax Sheltered Savings
Account for each Participant who makes an Elective Deferral.

        (b) The balance in each Participant's Tax Sheltered Savings Account
shall at all times be fully (100%) vested. At no time shall the balance in a
Participant's Tax Sheltered Savings Account be forfeited for any reason.

        5.04
        Adjustments to Elective Deferrals

        A Participant may increase or decrease the rate of Elective Deferrals
effective as of any pay period or at times as determined by the Plan
Administrator by submitting a new election to the Plan Administrator. A
Participant may suspend his Elective Deferrals at any time by submitting a
written 30 day notice to the Plan Administrator. Suspensions during the Plan
Year shall be effective as soon as practicable after the election is filed with
the Plan Administrator. Amounts attributable to elective deferrals may not be
distributed earlier than: 1. The employee's retirement, death, disability or
separation from service; 2. The termination of the plan without establishment of
another defined contribution plan, other than an employee stock ownership plan
(as defined in section 4975(e) or section 409 of the Code) or a simplified
employee pension plan as defined in section 408(k); 3. In the case of a profit
sharing or stock bonus plan, the employee's attainment of age 59 1/2 or the
employee's hardship; 4. The disposition by a corporation to an unrelated
corporation of substantially all of the assets (within the meaning of section
409(d) (2) of the Code) used in a trade or business of such corporation 



                                       36
<PAGE>   40

if such corporation continues to maintain this plan after the disposition, but
only with respect to employees who continue employment with the corporation
acquiring such assets; or 5. The disposition by a corporation to an unrelated
entity of such corporation's interest in a subsidiary (within the meaning of
section 409(d) (3) of the Code) if such corporation continues to maintain this
plan, but only with respect to employees who continue employment with the
subsidiary.

        5.05
        Actual Deferral Percentage

        (a) The Actual Deferral Percentage for Eligible Participants who are
Highly Compensated Employees for the Plan Year shall not exceed the Actual
Deferral Percentage for Eligible Participants who are Nonhighly Compensated
Employees for the Plan Year multiplied by 1.25; or

        (b) The Actual Deferral Percentage for Eligible Participants who are
Highly Compensated Employees for the Plan Year shall not exceed the Actual
Deferral Percentage for Eligible Participants who are Nonhighly Compensated
Employees for the Plan year multiplied by 2, provided that the Actual Deferral
Percentage for Eligible Participants who are Highly Compensated Employees does
not exceed the Deferral Percentage for Eligible Participants who are Nonhighly
Compensated Employees by more than two (2) percentage points or such lesser
amount as the Secretary of the Treasury shall prescribe to prevent the multiple
use of this alternative limitation with respect to any Highly Compensated
Employee.

        5.06
        Definitions. For purposes of this Article V and for purposes of Articles
XIV and XV of this Plan, the following definitions shall be used:

        (a) Actual Deferral Percentage shall mean for a specified group of
participants for a Plan Year, the average of the ratios (calculated separately
for each participant in such group) of (1) the amount of employer contributions
actually paid over the trust on behalf of such participant for the Plan Year to
(2) the participant's Compensation for such Plan Year. Employer contributions on
behalf of any participant shall include: (1) any Elective Deferrals made
pursuant to the participant's deferral election (including Excess Elective
Deferrals of Highly Compensated Employees) , but excluding (a) Excess Elective
Deferrals of Non-highly compensated Employees that arise solely from Elective
Deferrals made under the plan or plans of this employer and (b) Elective
Deferrals that are taken into account in the Contribution Percentage test
(provided the ADP test is satisfied both with and without exclusion of these
Elective Deferrals); and (2) at the election of the employer, Qualified
Non-elective Contributions and Qualified Matching Contributions. For purposes of
computing Actual Deferral percentages, an employee who would be a participant
but for the failure to make Elective Deferrals shall be treated as a participant
on whose behalf no Elective Deferrals are made.

        (b) Average Actual Deferral Percentage shall mean the average (expressed
as a percentage) of the Actual Deferral Percentage of the Eligible Participants
in a group.



                                       37
<PAGE>   41

        (c) Qualified Employer Deferral Contributions shall mean Qualified
Nonelective Contributions taken into account under the terms of the plan without
regard to this Article in determining the Actual Deferral Percentage.

        (d) Eligible Participant shall mean any employee who is directly or
indirectly eligible to make a cash or deferred election under the plan for all
or a portion of a plan year and includes: an employee who would be a plan
participant but for the failure to make required contributions; an employee
whose eligibility to make elective contributions has been suspended because of:
an election (other than certain one-time elections) not to participate, a
distribution, or a loan; an employee who cannot defer because of Code section
415 limits on annual additions; and, an employee who is unable to make an
elective contribution because his or her compensation is less than a stated
dollar amount. In the case of an eligible employee who makes no elective
contributions the deferral ratio that is to be included in determining the ADP
is zero. Employee for the Plan Year who is eligible to have Elective Deferrals
or Qualified Nonelective Employer Contributions and Qualified Matching
Contributions allocated to his account under two or more plans or arrangements
described in Section 401(k) of the Code that are maintained by the Employer or
an Affiliated Employer shall be determined as if all such Elective Deferrals and
Qualified Employer Deferral Contribution were made under a single arrangement.
Additionally, all elective contributions that are made under two or more plans
that are aggregated for purposes of Code Section 401(a) (4) or 410(b) (other
than section 410(b) (2) (A) (ii)) are to be treated as made under a single plan
and that if two or more plans are permissively aggregated for purposes of Code
Section 401(k), the aggregated plans must also satisfy Code Sections 401 (a) (4)
and 410(b) as though they were a single plan. Plans may not be permissively
aggregated after January 1, 1989 unless the plans have the same plan year.

        5.07
        Special Rules

        (a) For purposes of this Article V, the Actual Deferral Percentage for
any Eligible Participant who is a Highly Compensated Employee for the Plan Year
and who is eligible to have Elective Deferrals or Qualified Non-elective
Contributions or Qualified Matching Contributions or both if treated as Elective
Deferrals for purposes of the ADP test, allocated to his account under two or
more plans or arrangements described in Section 401(k) of the Code and all Plans
that have a plan year that end in the same calendar year shall be treated as a
single arrangement and all Plans that are maintained by the Employer or an
Affiliated Employer shall be determined as if all such Elective Deferrals and
Qualified Non-elective Contributions or Qualified Matching Contributions, or
both, were made under a single arrangement. Notwithstanding the foregoing,
certain plans shall be treated as separate if mandatorily desegregated under
regulations under section 401(k) of the Code.

        (b) For purposes of determining the Actual Deferral Percentage in the
case of a highly compensated employee who is either a 5% owner or one of the ten
most highly compensated employees and is thereby subject to the family
aggregation rules of section 414(q) (6), the actual deferral ratio (ADR) for the
family group (which is treated as one highly compensated employee) is the ADR
determined by combining the elective contributions, compensation, and amounts



                                       38
<PAGE>   42

treated as elective contributions of all eligible family members. Except to the
extent taken into account in the preceding sentence, the elective contributions,
compensation, and amounts treated as elective contributions of all family
members shall be disregarded as separate employees in determining the actual
deferral percentages for the groups of highly compensated employees and
nonhighly compensated employees.

        (c) The determination and treatment of the Elective Deferrals, Qualified
Nonelective Contributions, Qualified Matching Contributions, or both, and Actual
Deferral Percentage of any Participant shall satisfy such other requirements as
may be prescribed by the Secretary of the Treasury. The Employer shall maintain
records sufficient to demonstrate satisfaction of the ADP test and the amount of
Qualified Non-elective Contributions or Qualified Matching Contributions, or
both, used in such test.

        (d) For purposes of determining whether a plan satisfied the actual
deferral percentage test of Code section 401(k), all elective contributions that
are made under two or more plans that are aggregated for purposes of Code
section 401(a) (4) or 410(b) (other than section 410(b)(2)(A)(ii)) and that have
the same Plan Year are to be treated as made under a single plan and that is two
or more plans are permissively aggregated for purposes of Code section 401(k),
the aggregated plans must also satisfy sections 401(a)(4) and 410(b) of the Code
as though they were a single plan.

        (e) For purposes of determining the ADP test, Elective Deferrals,
Qualified Non-elective Contributions, and Qualified Matching Contributions must
be made before the last day of the 12th month period immediately following the
plan year to which the contributions relate.

      ARTICLE VI -- ALLOCATION OF EMPLOYER CONTRIBUTIONS AND LIMITATIONS ON
                           CONTRIBUTIONS AND BENEFITS

        6.01
        Allocation of Employer Contributions

        Employer Contributions shall be allocated in accordance with the
Adoption Agreement Section (7) (B) and Article XVII if the plan provides for
permitted disparity or social security integration.

        6.02
        Allocation of Forfeitures

        Except as otherwise provided in Section 8.05, any forfeiture arising
under Section 6.03 shall be allocated as if it were an Employer contribution.

        6.03
        Timing of Forfeitures

        No forfeiture shall be made unless, a Participant has a Termination of
Employment and five consecutive one year breaks in service or a distribution as
described in Section 8.01(a) is made, the non-vested portion of the
Participant's Account shall be forfeited on the earlier of (1) the last day of
the first Plan Year in which the Participant receives a distribution in
accordance with Section 8.04(a)(l), or (2) the last day of the first Plan Year
in which a Break in Service occurs in all other cases.

        6.04
        Limitations on Contribution and Benefits

        (a) For purposes of this section 6.04, the following terms shall be
defined as follows:

        (1) Annual Additions--The sum of the following amounts allocated on
behalf of a Participant for a Limitation Year:

                (A) all Employer contributions,

                (B) all forfeitures,

                (C) all employee contributions, and annual additions include
excess contributions described in Code Section 401(k), excess aggregate
contributions described in Code Section 401(m) and excess deferrals described in
Code 402 (g), irrespective of whether the plan distributes or forfeits such
excess amounts. Annual additions also include excess amounts re-applied to
reduce employer contributions under section 6.02 of the plan. Annual additions
include all contributions after March 31, 1984 to an individual medical account,
as defined in section 415(1) (2) of the Code, which is part of a defined benefit
plan maintained by the Employer, and amounts derived from contributions paid or
accrued after December 31, 1985, in taxable years ending after such date, which
are attributable to post-retirement medical benefits, as 



                                       40
<PAGE>   44

defined in Code Section 419A(d) (3), allocated to the separate account of a Key
Employee, under a welfare benefit fund, as defined in Code Section 419(e),
maintained by the Employer.

        For purposes of this section 6.04, amounts re-applied to reduce Employer
contributions under paragraph 6.04(b) (4) shall also be included as Annual
Additions.

        (2) (A) "Compensation" means for any Limitation Year, the definition as
set out in Article II, Section 12.

        (3) "Defined Benefit Plan" means any Retirement Plan that is not a
Defined Contribution Plan.

        (4) "Defined Benefit Plan Fraction" means a fraction, the numerator of
which is the sum of the Participant's Projected Annual Benefits under all the
Defined Benefit Plans (whether or not terminated) maintained by the Employer,
and the denominator of which is the lesser of (1) 125 percent of the dollar
limitation in effect for the Limitation Year under Section 415(b) & (d) of the
Code, or (2) 140 percent of the Participant's Highest Average Compensation taken
over three (3) consecutive Years of Service.

        Notwithstanding the above if the Participant was a Participant as of the
first day of the first limitation year beginning after December 31, 1986, in one
or more defined benefit plans maintained by the employer which were in existence
on May 6, 1986, the denominator of this fraction will be not less than 125
percent of the sum of the annual benefits under such plans which the participant
had accrued as of the close of the last limitation year beginning before January
1, 1987, disregarding any changes in the terms and conditions of the plan after
May 5, 1986. The preceding sentence applies only if the defined benefit plans
individually and in the aggregate satisfied the requirements of section 415 of
the Code for all limitation years beginning before January 1, 1987.

        (5) "Defined Contribution Plan" means a Retirement Plan which provides
for an individual account for each participant and for benefits based solely on
the amount contributed to such account and any income, expense, gains and
losses, and forfeitures of accounts of other participants which may be allocated
to such account.

        (6) "Defined Contribution Plan Fraction" means a fraction, the numerator
of which is the sum of the Annual Additions to the Participant's account under
all the Defined Contribution Plans (whether or not terminated) and all
contributions to individual medical accounts as defined in Section 415(1) (2) of
the Code maintained by the Employer for the current and all prior Limitation
Years described in Section 415(b) & (d) of the Code (including the Annual
Additions attributable to the Participant's non-deductible employee
contributions to all Defined Benefit Plans, whether or not terminated,
maintained by the Employer and the Annual Additions attributable to all welfare
benefit funds as described in Section 6.04(a)(l)(D) of the Plan), and the
denominator of which is the sum of the maximum aggregate amounts for the current
and all prior Limitation Years of service with the Employer (regardless of
whether a Defined Contribution Plan was maintained by the Employer). The maximum
aggregate amount in any Limitation Year



                                       41
<PAGE>   45

is the lesser of (1) 125 percent of the dollar limitation in effect under
Section 415(c) (1) (A) of the Code, or (2) 35 percent of the Participant's
Compensation for the Limitation Year.

        If the Employee was a participant as of the end of first day of the
first limitation year beginning after December 31, 1986, in one or more defined
contribution plans maintained by the employer which were in existence on May 6,
1986, the numerator of this fraction will be adjusted if the sum of this
fraction and the defined benefit fraction would otherwise exceed 1.0 under the
terms of this plan. Under the adjustment, an amount equal to the product of (1)
the excess of the sum of the fractions over 1.0 times (2) the denominator of
this fraction, will be permanently subtracted from the numerator of this
fraction. The adjustment is calculated using the fractions as they would be
computed as of the end of the last limitation year beginning before January 1,
1987, and disregarding any changes in terms and conditions of the plan made
after May 5, 1986, but using the section 415 limitation applicable to the first
limitation year beginning on or after January 1, 1987. The annual addition for
any limitation year beginning before January 1, 1987, shall not be recomputed to
treat all employee contributions as annual additions.

        (7) "Employer" means the Employer that adopts this Plan. In the case of
a group of employers which constitutes a controlled group of corporations (as
defined in section 414(b) of the Code, as modified by section 415(h)) which
constitutes trades or businesses (whether or not incorporated) which are under
common control (as defined in Code Section 414(c), as modified by section
415(h)), or which forms part of an Affiliated Service Group (as defined in Code
Section 414(m)) or a separate organization, employee leasing or other
arrangement described in Code Section 414(0) or the regulations prescribed under
the Code Section all such employers or groups shall be considered a single
Employer for purposes of applying the limitations of this Section 6.04.

        (8) "Excess Amount" means the value of the excess of Annual Additions to
a Participant's Account for the Limitation Year over the Maximum Permissible
Amount.

        (9) "Highest Average Compensation". The Average Compensation for the
three consecutive Years of Service with the Employer that produces the highest
average. A Year of Service with the Employer is the 12-consecutive month period
defined in Section 2.45 of the Plan.

        (10) "Limitation Year" means the calendar year unless a different
limitation year is chosen in the Adoption Agreement. All plans of the Employer
or the Affiliated Service Group shall have the same Limitation Year. If the
limitation year is amended to a different 12 consecutive month period, the new
limitation year must begin on a date within the limitation year in which the
amendment is made.

        (11) "Regional Prototype Plan" means this basic plan and any amendments
the form of which is the subject of a favorable opinion letter from the Internal
Revenue Service.

        (12) "Maximum Permissible Amount" means the lesser of (1) $30,000, or
such larger amount equal to 1/4 of the defined benefit dollar limitations as
adjusted for cost-of-living increases pursuant to IRC sections 415(d)(l) and
415(d)(3), or (2) 25 percent of the Participant's



                                       42
<PAGE>   46

Compensation for the Limitation Year. If a short Limitation Year is created
because of an amendment changing the Limitation Year to a different 12
consecutive months period, the Maximum Permissible Amount will not exceed
$30,000 multiplied by the following fraction:

                  Number of months in the short Limitation Year
    -------------------------------------------------------------------------
                                       12

        (13) "Projected Annual Benefit" means the annual retirement benefit
(adjusted to an actuarially equivalent straight life annuity if such benefit is
expressed in a form other than a straight life annuity or qualified joint and
survivor annuity) to which the Participant would be entitled under the terms of
the Plan assuming:

                (A) the Participant will continue employment until normal
retirement age under the Plan (or current age, if later), and

                (B) the Participant's Compensation for the current Limitation
Year and all other relevant factors used to determine benefits under the Plan
will remain constant for all future Limitation Years.

        (14) "Retirement Plan" means any plan maintained by an Employer which is
(1) a pension, profit-sharing, stock bonus or cash or deferred arrangement plan
described in Sections 401(a) and 501(a) of the Code, (2) an annuity plan or
annuity contract described in Section 403(a) or 403(b) of the Code or (3) a
qualified bond purchase plan described in Section 405(a) of the Code.

        (b) (1)If the Participant does not participate in, and has never
participated in another qualified plan or welfare benefit fund as defined in
Section 419(e) of the Code or an individual medical account which is part of any
pension or annuity plan described in Code Section 415(1) (2) maintained by the
Employer, the amount of Annual Additions which may be credited to the
Participant's Account for any Limitation Year will not exceed the lesser of (A)
the Maximum permissible Amount, or (B) any other limitation contained in this
Plan. If the Employer contribution that would otherwise be contributed or
allocated to the participant's Account would cause the Annual Additions for the
Limitation Year to exceed the Maximum Permissible Amount, the amount contributed
or. allocated will be reduced so that the Annual Additions for the Limitation
Year will equal the Maximum Permissible Amount.

        (2) Prior to determining the Participant's actual compensation for the
Limitation Year, the Employer may determine the Maximum Permissible Amount for a
Participant on the basis of a reasonable estimation of the Participant's
Compensation for the Limitation Year, uniformly determined for all Participants
similarly situated.

        (3) As soon as is administratively feasible after the end of the
Limitation Year, the Maximum Permissible Amount for the Limitation Year will be
determined on the basis of the Participant's actual Compensation for the
Limitation Year.



                                       43
<PAGE>   47

        (4) If there is an Excess Amount, the excess will be disposed of as
follows:

                (A) Any non-deductible voluntary employee contributions, to the
extent they would reduce the Excess Amount, will be returned to the Participant;

                (B) If after the application of Paragraph (A) an Excess Amount
still exists, and the Participant is covered by the Plan at the end of the
Limitation Year, the Excess Amount in the Participant's Account will be used to
reduce Employer contributions (including any allocation of forfeitures) for such
Participant in the next Limitation Year, and each succeeding Limitation Year, if
necessary.

                (C) If after the application of Paragraph (A) an Excess Amount
still exists, and the Participant is not covered by the Plan at the end of the
Limitation Year, the Excess Amount will be held in the Unallocated Suspense
Account. The amount in the Unallocated Suspense Account will be applied to
reduce future Employer contributions (including allocation of any forfeitures)
for all remaining Participants in the Next Limitation Year, and each succeeding
Limitation Year, if necessary.

                (D) If the Unallocated Suspense Account is in existence at any
time during the Limitation Year pursuant to this section, it will not
participate in the allocation of the Trust's investment gains and losses. If a
suspense account is in existence at any time during a particular limitation
year, all amounts in the suspense account must be allocated and reallocated to
participants' accounts before any employer or employee contributions may be made
to the plan for that limitation year. Excess amounts may not be distributed to
participants or former participants.

        (c) This Subsection (c) (1) applies to Employers who, in addition to
this Plan, maintain one or more other qualified Regional Prototype Defined
Contribution Plan(s) or welfare benefit funds.

        (1) If, in addition to this Plan, the Participant is covered under
another qualified Regional Prototype Defined Contribution Plan(s), welfare
benefit fund as defined in Section 419(e) of the Code or Individual Medical
Account(s) as defined under section 415(1) (2) of the Code maintained by the
Employer during any Limitation Year, the Annual Additions which may be credited
to a Participant's Account under this Plan for any such Limitation Year will not
exceed the Maximum Permissible Amount reduced by the Annual Additions credited
to a Participant's Account under the other plans and welfare benefit funds for
the same Limitation Year. If the Annual Additions with respect to the
Participant under other Defined Contribution Plans and welfare benefit funds
maintained by the Employer are less than the Maximum Permissible Amount and the
Employer contribution that would otherwise be contributed or allocated to the
Participant's Account under this Plan would cause the Annual Additions for the
Limitation Year to exceed this limitation, the amount contributed or allocated
will be reduced so that the Annual Additions under all such Plans and funds for
the Limitation Year will equal the Maximum Permissible Amount. If the Annual
Additions with respect to the Participant under such other Defined Contribution
Plans and welfare benefit funds in the aggregate are equal to or 



                                       44
<PAGE>   48

greater than the Maximum Permissible Amount, no amount will be contributed or
allocated to the Participant's Account under this Plan for the Limitation Year.

        (2) Prior to determining the Participant's actual Compensation for the
Limitation Year, the Employer may determine the Maximum Permissible Amount for a
Participant in the manner described in Section 6.04(b)(2).

        (3) As soon as is administratively feasible after the end of the
Limitation Year, the Maximum Permissible Amount for the Limitation Year will be
determined on the basis of the Participant's actual Compensation for the
Limitation Year.

        (4) If, pursuant to Section 6.04(c) (3), a Participant's Annual
Additions under this Plan and such other plans would result in an Excess Amount
for a Limitation Year, the Excess Amount will be deemed to consist of the Annual
Additions last allocated, except that Annual Additions attributable to a welfare
benefit fund or individual medical account, as defined in Section 415(1) (2) of
the Code, maintained by the Employer, will be deemed to have been allocated
first regardless of the actual allocation date.

        (5) If an Excess Amount was allocated to a Participant on an allocation
date of this Plan which coincides with an allocation date of another plan, the
Excess Amount attributed to this Plan will be the product of:

                (A) the total Excess Amount allocated as of such date, times.

                (B) the ratio of (i) the Annual Additions allocated to the
Participant for the Limitation Year as of such date under this Plan to (ii) the
total Annual Additions allocated to the Participant for the Limitation Year as
of such date under this and all the other qualified Defined Contribution Plans.

        (6) Any Excess Amount attributed to this Plan will be disposed in the
manner described in Section 6.04(b) (4).

        (d) This Subsection applies to Employers who maintain another qualified
Defined Contribution Plan which is not a Regional Prototype Plan. If the
Participant is covered under another qualified Defined Contribution Plan
maintained by the Employer which is not a Regional Prototype Plan, Annual
Additions which may be credited to the Participant's Account under this Plan for
any Limitation Year will be limited in accordance with Sections 6.04(c)(l)
through 6.04(c)(6) as though the other plan were a Regional Prototype Plan.

        (e) This Subsection applies to an Employer who maintains, or at any time
maintained, a qualified Defined Benefit Plan. If the Employer maintains, or at
any time maintained, a qualified Defined Benefit Plan covering any Participant
in this Plan, the sum of the Participant's Defined Benefit Plan Fraction and
Defined Contribution Plan Fraction will not exceed 1.0 in any Limitation Year.
The Annual Additions which may be credited to the Participant's Account under
this Plan for any Limitation Year will be limited in accordance with the
Adoption Agreement.

        6.05
        Super Top-Heavy Adjustments

        In any Plan Year which the Top-Heavy Ratio exceeds 90% (i.e., becomes
Super Top-Heavy) the denominators of the Defined Benefit Plan Fraction and
Defined Contribution Plan Fraction (as described in IRC Section 415(e)) shall be
computed substituting a factor of 1.0 for 1.25.

        6.06
        Integration of Paired Plans

        If the Employer adopts this Plan and another plan that qualifies under
Code Section 401 only one Plan may be integrated.

        6.07
        Compensation Limit

        Compensation taken into account under the plan shall not exceed
$200,000, adjusted for changes in the cost of living as provided in section
415(d) of the Internal Revenue Code, for the purpose of calculating a plan
participant's account balance (including the right to any optional benefit
provided under the plan) for any plan year commencing after December 31, 1988.

        6.08
        Coordination of Top-Heavy Minimum

        If the top-heavy ratio does not exceed 90% and the employer uses a
factor of 1.25 in the denominator of the Code Section 415 fraction, one of the
following conditions must be met:

        (a) A defined benefit minimum of 3% per year of service (up to 30%) is
provided, or

        (b) For participants covered only by a defined contribution plan, a
defined contributions minimum of 4% is provided, or

        (c) For participants covered by both types of plans, benefits from the
defined contribution minimum are comparable to the 3% defined benefit minimum,
or

        (d) The plan provides a floor offset where the floor is 3% defined
benefit minimum, or

        (e) A defined contribution minimum of 7 1/2% of compensation is provided
for any non-key employee who is covered under both a defined benefit plan and a
defined contribution plan (each of which is top-heavy) of an employer.

                         ARTICLE VII -- TOP-HEAVY RULES

        7.01
        Definitions--For purposes of this Article VII the following terms shall
be defined as follows:

        (a) "Determination Date" means for any Plan Year after the first Plan
Year, the last day of the preceding Plan Year. For the first Plan Year, the last
day of that year.

        (b) "Permissive Aggregation Group" means the Required Aggregation Group
of plans plus any other plan or plans of the Employer which, when considered as
a group with the Required Aggregation Group, would continue to satisfy the
requirements of Section 401(a)(4) and 410 of the Code.

        (c) "Present Value" means a benefit of equivalent value and shall be
based only on the interest and mortality rates specified in the defined benefit
plan. In the absence of such specifications in the defined benefit plan, Present
Value shall be determined by applying the then current purchase rates for
qualified, single payment non-participating immediate annuities issued by the
Insurance Company and discounting the resulting value by 6 percent per annum.

        (d) "Required Aggregation Group" means (1) each qualified plan of the
Employer in which at least one Key Employee participates in the plan year
containing the determination date or any of the four preceding plan years, and
(2) any other qualified plan of the Employer which enables a plan described in
this Subsection (d) to meet the requirements of Sections 401(a) (4) or 410 of
the Code, are required to be aggregated for top-heavy testing purposes and are
considered the required aggregation group. All employers aggregated under
sections 414(b), (c) or (m) are considered a single employer.

        (e) "Top-Heavy Plan" means for any Plan Year beginning after December
31, 1983, this plan, if any of the following conditions exists:

                (1) If the Top-Heavy Ratio for this Plan exceeds 60 percent and
this Plan is not part of any Required Aggregation Group or Permissive
Aggregation Group of plans

                (2) If this Plan is a part of a Required Aggregation Group of
plans but not part of a Permissive Aggregation Group and the Top-Heavy Ratio for
the Required Aggregation Group of plans exceeds 60 percent.

                (3) If this Plan is a part of a Required Aggregation Group and
part of a Permissive Aggregation Group of plans and the Top-Heavy Ratio for the
Permissive Aggregation Group exceeds 60 percent.

                This Plan is "Super Top-Heavy" if any of the above described
conditions exists when "90 percent" is substituted for "60 percent" each place
that it appears.

        (f) "Top-Heavy Ratio" means



                                       47
<PAGE>   51

        (1) If the Employer maintains one or more defined contribution plans
(including any Simplified Employee Pension Plan) and the Employer has not
maintained any defined benefit plan which during the 5-year period ending on the
Determination Date(s) has or has had accrued benefits, the Top-Heavy Ratio for
this Plan alone or for the Required or Permissive Aggregation Group, as
appropriate, is a fraction, the numerator of which is the sum of the Account
balances of all Key Employees as of the Determination Date(s) (including any
part of any account balance distributed in the 5-year period ending on the
Determination Date(s)), and the denominator of which is the sum of all account
balances (including any part of any account balance distributed in the 5-year
period ending on the Determination Date(s)), both computed in accordance with
Section 416 of the Code and the regulations thereunder. Both the numerator and
denominator of the Top-Heavy Ratio are increased to reflect any contribution not
actually made as of the Determination Date, but which is required to be taken
into account on that date under Section 416 of the Code and the regulations
thereunder.

        (2) If the Employer maintains one or more defined contribution plans
(including any Simplified Employee Pension Plans) and the Employer maintains or
has maintained one or more defined benefit plans which during the 5-year period
ending on the Determination Date(s) has or has had any accrued benefits, the
Top-Heavy Ratio for any Required or Permissive Aggregation Group, as
appropriate, is a fraction, the numerator of which is the sum of account
balances under the aggregated defined contribution plan or plans for all Key
Employees, determined in accordance with Paragraph (1), and the Present Value of
accrued benefits under the aggregated defined benefit plan or plans for all Key
Employees as of the Determination Date(s) , and the denominator of which is the
sum of the account balances under the aggregated defined contribution plan or
plans for all Participants, determined in accordance with Paragraph (1), and the
Present Value of accrued benefits under the defined benefit plan or plans for
all Participants as of the Determination Date(s), all determined in accordance
with Section 416 of the Code and the regulations thereunder. The accrued
benefits under a defined benefit plan in both the numerator and denominator of
the Top-Heavy Ratio are increased for any distribution of an accrued benefit
made in the 5-year period ending on the Determination Date.

        (3) For purposes of Paragraphs (1) and (2) , the value of Account
balances and the Present Value of Accrued Benefits will be determined as of the
most recent Valuation Date that falls within or ends with the 12-month period
ending on the Determination Date, except as provided in Section 416 of the Code
and the regulations thereunder for the first and second plan years of a defined
benefit plan. The Account balances and accrued benefits of a Participant (1) who
is not a Key Employee but who was a Key Employee in a prior year, or (2) who has
not been credited with at least one hour of service for any Employer maintaining
the Plan at any time during the 5-year period ending on the Determination Date
will be disregarded. The calculation of the Top-Heavy Ratio, and the extent to
which distributions, roll-overs, and transfers are taken into account will be
made in accordance with Section 416 of the Code and the regulations thereunder.
Deductible Employee contributions will not be taken into account for purposes of
computing the Top-Heavy Ratio. When aggregating plans, the value of Account
balances and accrued benefits will be calculated with reference to the
Determination Dates that fall within the same calendar year. The accrued benefit
of a participant other than a key employee shall be determined under (a) the
method, if any, that uniformly applies for accrual purposes under all 



                                       48
<PAGE>   52

defined benefit plans maintained by the employer, or (b) if there is no such
method, as if such benefit accrued not more rapidly than the slowest accrual
rate permitted under the fractional rule of section 4"(b) (1) (C) of the Code.

        (g) "Allocation Date" means the date specified in Article 2.05 as of
which Account balances or accrued benefits are valued for purposes of
calculating the Top-Heavy Ratio.

        7.02
        Minimum Contributions

        (a) Except as otherwise provided in Subsections (c) and (d) for any Plan
Year in which the Plan is a Top-Heavy Plan, the Employer contributions and
forfeitures allocated on behalf of any Participant who is not a Key Employee
shall not be less than the lesser of (1) three percent (3%) of such
Participant's Compensation, or (2) in the case where the Employer has no defined
benefit plan which designates this Plan to satisfy Section 401 of the Code, the
largest percentage of Employer contributions and forfeitures expressly allocated
on behalf of any Key Employee for that year as a percentage of the first
$200,000 of the Key Employee's compensation, and shall include amounts
contributed as a result of a salary reduction agreement. The minimum
contribution is determined without regard to any Social Security contribution.
This minimum contribution shall be made even though, under other Plan
provisions, the Participant would not otherwise be entitled to receive such
contribution, or would have received a lesser allocation for (i) the year
because of the Participant's failure to complete 1,000 Hours of Service (or any
equivalent provided in the Plan) , or (ii) the Participant's failure to make
mandatory employee contributions to the Plan, or (iii) compensation less than a
stated amount.

        (b) For purposes of computing the minimum contribution, "Compensation"
will means Compensation as defined in this Plan.

        (c) The requirements of Subsection (a) shall not apply to any
Participant who was not employed by the Employer on the last day of the Plan
Year.

        (d) The requirements of Subsection (a) shall not apply to any
Participant to the extent the Participant is covered under any other plan or
plans of the Employer and the minimum contribution or benefit requirement
applicable to Top-Heavy Plans will be met in such other plan or plans.

        (e) After January 1, 1989, this plan may not include elective deferrals
or matching contributions as Employer contributions for the purpose of
satisfying the minimum contributions requirement.

        7.03
        Nonforfeitability of Minimum Contribution

        The minimum contribution required (to the extent required to be
nonforfeitable under Code Section 416(b)) may not be forfeited under Code
Section 4"(a)(3)(B) or Code Section 4"(a)(3)(D).



                                       49
<PAGE>   53

        7.04
        Compensation Limit

        For any Plan Year, only the first $200,000 (or such larger amount as may
be prescribed by the Secretary of the Treasury or his delegate) of a
Participant's annual Compensation shall be taken into account for purposes of
determining Employer contributions under the Plan.

        7.05
        Minimum Vesting for Non-Standardized Plans

        For any Plan Year in which this Plan is a Top-Heavy Plan, one of the
minimum vesting schedules as elected by the Employer in the Adoption Agreement
will automatically apply to the Plan. The minimum vesting schedule applies to
all benefits within the meaning of Section 411(a)(7) of the Code except those
attributable to Employee contributions, including benefits accrued before the
effective date of Code Section 416 and benefits accrued before the Plan became
Top-Heavy. Further, no decrease in a Participant's nonforfeitable percentage may
occur in the event the Plan's status as Top-Heavy changes for any Plan Year.
However, this section does not apply to the Account balances of any Employee who
does not have an Hour of Service after the Plan has initially become Top-Heavy
and such Employee's Account balance attributable to Employer contributions and
forfeitures will be determined without regard to this Section 7.05. If the Plan
is top-heavy then the vesting schedule selected in the Adoption Agreement
Section 9(B) shall apply. If the vesting schedule under the Plan shifts in or
out of the above schedule for any Plan Year because of the Plan's top-heavy
status, such shift is an amendment to the vesting schedule and the election in
this Section of the Plan.

        7.06
        Coordination of Top-Heavy Plan Minimum Contribution

        If an Employer and Affiliated Employer maintain both defined
contribution and defined benefit plans, the top-heavy minimums shall be
coordinated by providing that contributions and forfeitures under the defined
contribution plan equal 5% of compensation for each year the plan is top-heavy.

                       ARTICLE VIII -- PAYMENT OF BENEFITS

        8.01
        Form of Distributions

        (a) Following a Termination of Employment but in no event later than
April 1st of the calendar year following the year in which a 5% owner (as
defined in Section 416(i) of the Code) attains age 70-1/2, the vested portion of
a Participant's Account balance shall be distributed, subject to the provision
of section 8.02, to him, or in the event of the Participant's death, to his
Beneficiary in one lump sum. A Participant may elect to receive any benefit in
cash, installments, or subject to Subsection (b), apply all or a portion of the
cash to the purchase of an immediate or deferred non-transferable annuity
contract. A Participant may also elect, subject to the provisions of Subsection
(d), to receive the life insurance contracts, if any, held on his life. However,
a deferred annuity may not be purchased on behalf of a terminated Participant
who has attained age 70-1/2. Optional forms of benefits shall be made available
to Participants in a manner that does not discriminate in favor of highly
compensated participants. Distributions to each participant shall commence no
later than the participant's required beginning date. Required Beginning Date
means April 1st of the calendar year following the calendar year in which the
employee attains age 70-1/2. If a Participant dies his interest shall be
distributed at least as rapidly as his benefit was being distributed and in no
event may the distribution take longer than five years from the date of death.
Any distribution required under the incidental death benefit requirement of Code
Section 401(a)(9)(G) shall be treated as a distribution for the purposes of
this plan section. The provisions reflecting Code Section 401(a)(9) and
Proposed Treasury Regulations 1.401(a)(9)-2 shall override any distribution
options in this plan which are inconsistent with Code Section 401(a)(9) and
Proposed Treasury Regulation 1-401(a)(9)-2.

        (b)(1) For purposes of this Article VIII, "Designated Beneficiary" means
any individual designated as a Beneficiary by the Participants as defined in
Section 401(a)(9) of the Code and the proposed regulations thereunder.

        (2) Any annuity purchased shall comply with all requirements of the Plan
and pursuant to Subsection (a) or (c) must be payable over the Participant's
life (or over the joint lives of the Participant and Designated Beneficiary) .
Such annuity will be non-transferable and will provide for non-increasing
payments and may provide for an annuity certain feature. If an annuity certain
feature applies such period may not exceed the joint and last survivor
expectancy of the Participant and his Designated Beneficiary, as the case may
be. An annuity certain feature shall have a payment period which shall be
greater than 50% of the annuity which is payable during the joint lives of the
participant and the spouse. A participant who elects to defer receipt of
benefits shah not do so to the extent that the participant is creating a death
benefit that is more than incidental. Life expectancy will be determined not
later than the date distribution must commence under Subsection (a) or (c) of
this Article.

        (3) Individual Account

                (A) If a participant's benefit is to be distributed over (1) a
period not extending beyond the life expectancy of the 



                                       51
<PAGE>   55

participant or the joint life and last survivor expectancy of the participant
and the participant's designated beneficiary or (2) a period not extending
beyond the life expectancy of the designated beneficiary, the amount required to
be distributed for each calendar year, beginning with distributions for the
first distribution calendar year, must at least equal the quotient obtained by
dividing the participant's benefit by the applicable life expectancy.

                (B) For calendar years beginning before January 1, 1989, if the
participant's spouse is not the designated beneficiary, the method of
distribution selected must assure that at least 50% of the present value of the
amount available for distribution is paid within the life expectancy of the
participant.

                (C) For calendar years beginning after December 31, 1988, the
amount to be distributed each year, beginning with distributions for the first
distribution calendar year shall not be less than the quotient obtained by
dividing the participant's benefit by the lessor of (l) the applicable life
expectancy or (2) if the participant's spouse is not the designated beneficiary,
the applicable divisor determined from the table set forth in Q&A-4 of section
1.401(a)(9)-2 of the proposed regulations. Distributions after the death of the
participant shall be distributed using the applicable life expectancy in section
4.1(a) above as the relevant divisor without regard to Proposed Regulations
section 1.401(a)(9)-2.

                (D) The minimum distribution required for the participant's
first distribution calendar year must be made on or before the participant's
required beginning date. The minimum distribution for other calendar years,
including the minimum distribution for the distribution calendar year in which
the employee's required beginning date occurs, must be made on or before
December 31 of that distribution calendar year. For distributions beginning
before the participant's death, the first distribution calendar year is the
calendar year immediately preceding the calendar year which contains the
participant's required beginning date. For distributions beginning after the
participant's death, the first distributions calendar year is the calendar year
in which distributions are required to begin according to this section
hereinabove.

                (E) Participant's benefit shall mean the account balance as of
the last valuation date in the calendar year immediately preceding the
distribution calendar year (valuation calendar year) increased by the amount of
any contribution or forfeitures allocated to the account balance as of dates in
the valuation calendar year after the valuation date and decreased by
distributions made in the valuation calendar year after the valuation date. For
purposes of this paragraph, if any portion of the minimum distribution for the
first distribution calendar year is made in the second distribution calendar
year on or before the required beginning date, the amount of the minimum
distribution made in the second distribution calendar year shall be treated as
if it had been made in the immediately preceding distribution calendar year.

        (c) If a Participant who has attained age 70-1/2 remains employed by the
Employer then contributions will continue to be made for the Participant to the
extent required under Section 4.01. However, in the case of a 5% owner, in
addition to any benefit otherwise receivable by such Participant from
contributions made previously, an additional distribution will be made. The
amount of the distribution will be, subject to the provisions of Section 7.02,
the lump sum value of the Participant's Account or, at the election of the
Participant, the value of the 



                                       52
<PAGE>   56
Account will be applied to purchase an immediate annuity. Distributions to each
participant shall commence no later than the participants required beginning
date. Any distribution required under the incidental death benefit requirement
of Code Section 401(a)(9)(G) shall be treated as a distribution for the purposes
of this plan section. The provisions reflecting Code Section 401(a)(9) and
Proposed Treasury Regulation 1.401(a) (9)-2 shall override any distribution
options in this Plan which is inconsistent with the Code Section 401(a)(9) and
Proposed Treasury Regulation l.401(a)(9)-2.

         (d)(1) A Participant who is entitled to a distribution under this
Section of the Plan and who is fully (100%) vested in the balance of his
contribution Account may elect to receive a distribution of any life insurance
contracts issued on his life. If the Participant is not fully (100%) vested at
the time distribution commences and if such life insurance contracts would
otherwise be surrendered by the Plan, the Participant may purchase the
contracts. The Participant will pay the Plan the amount necessary to put the
Plan in the same cash position as it would have been in if the Trustees had
surrendered the contract and distributed the Participant's vested interest in
the Plan. Any amount paid to a child of the participant will be treated as if it
had been paid to the surviving spouse if the amount becomes payable when the
child reaches the age of majority.

        (2) Upon the request of a Participant described in Paragraph (1) , the
Trustees may borrow all or any portion of the cash surrender value of any life
insurance policy issued on such Participant's life and then sell the contract to
the Participant subject to the loan. Loans from insurance contracts for any
other purpose, except as specified in Section 9.04, shall be prohibited under
this Plan.

         (3) If a Participant who has a Termination of Employment does not
purchase the policy or policies issued on his life under this Section 8.01(d),
the policy or policies on his life shall be surrendered by the Trustees(1) the
cash surrender proceeds shall be added to his Account and distributed under the
provisions of this Article VIII.

        (4) A Participant shall elect the manner in which his vested Account
balance is to be distributed by signing a written statement and, if necessary,
making a Qualified Election on a form satisfactory to the Trustees and the
Insurer, if required, within a reasonable time before or after his Termination
of Employment. If a Participant fails to make a valid election of a manner of
distribution within the time specified by the Trustees, the distribution shall
be made in one sum, or installments, except to the extent otherwise provided in
Section 8.02(b).

        (5) A Participant with vested benefits attributable to Employee or
Employer contributions, who survives until the Annuity Starting Date, (which is
the earlier of the first day of the first period for which an amount payable as
an annuity or in the case of a benefit not payable in the form of an annuity,
the first day on which all events have occurred which entitle the participant or
beneficiary to such benefit) shall receive benefits in the form of a qualified
joint and survivor annuity. For an unmarried participant a qualified joint and
survivor annuity shall mean a single life annuity.



                                       53
<PAGE>   57

        (6) If the value of a participant's vested account balance derived from
employer and employee contributions exceeds (or at the time of any prior
distribution exceeded) $3,500.00, and the account balance is immediately
distributable, the participant and the participant's spouse (or where either the
participant or the spouse has died, the survivor) must consent to any
distribution of such account balance. The consent of the participant and the
participant's spouse shall be obtained in writing within the 90-day period
ending on the annuity starting date. The annuity starting date is the first day
of the first period for which an amount is paid as an annuity or any other form.
The plan administrator shall notify the participant and the participant's spouse
of the right to defer any distribution until the participant's account balance
is no longer immediately distributable. Such notification shall include a
general description of the material features, and an explanation of the relative
values of, the optional forms of benefit available under the plan in a manner
that would satisfy the notice requirements of section 417(a)(3), and shall be
provided no less than 30 days and no more than 90 days prior to the annuity
starting date.

Notwithstanding the foregoing, only the participant need consent to the
commencement of a distribution in the form of a qualified joint and survivor
annuity while the account balance is immediately distributable. (Furthermore, if
payment in the form of a qualified joint and survivor annuity is not required
with respect to the participant pursuant to section 8.2 of the plan, only the
participant need consent to the distribution of an account balance that is
immediately distributable.) Neither the consent of the participant nor the
participant's spouse shall be life under this Section 8.01(d), the policy or
policies on his life shall be surrendered by the Trustees, the cash surrender
proceeds shall be added to his Account and distributed under the provisions of
this Article VIII.

        (4) A Participant shall elect the manner in which his vested Account
balance is to be distributed by signing a written statement and, if necessary,
making a Qualified Election on a form satisfactory to the Trustees and the
Insurer, if required, within a reasonable time before or after his Termination
of Employment. If a Participant fails to make a valid election of a manner of
distribution within the time specified by the Trustees, the distribution shall
be made in one sum, or installments, except to the extent otherwise provided in
Section 8.02(b).

        (5) A Participant with vested benefits attributable to Employee or
Employer contributions, who survives until the Annuity Starting Date, (which is
the earlier of the first day of the first period for which an amount payable as
an annuity or in the case of a benefit not payable in the form of an annuity,
the first day on which all events have occurred which entitle the participant or
beneficiary to such benefit) shall receive benefits in the form of a qualified
joint and survivor annuity. For an unmarried participant a qualified joint and
survivor annuity shall mean a single life annuity.

        (6) If the value of a participant's vested account balance derived from
employer and employee contributions exceeds (or at the time of any prior
distribution exceeded) $3,500.00, and the account balance is immediately
distributable, the participant and the participant's spouse (or where either the
participant or the spouse has died, the survivor) must consent to any
distribution of such account balance. The consent of the participant and the
participant's spouse shall be obtained in writing within the 90-day period
ending on the annuity 



                                       54
<PAGE>   58

starting date. The annuity starting date is the first day of the first period
for which an amount is paid as an annuity or any other form. The plan
administrator shall notify the participant and the participant's spouse of the
right to defer any distribution until the participant's account balance is no
longer immediately distributable. Such notification shall include a general
description of the material features, and an explanation of the relative values
of, the optional forms of benefit available under the plan in a manner that
would satisfy the notice requirements of section 417(a)(3), and shall be
provided no less than 30 days and no more than 90 days prior to the annuity
starting date.

Notwithstanding the foregoing, only the participant need consent to the
commencement of a distribution in the form of a qualified joint and survivor
annuity while the account balance is immediately distributable. (Furthermore, if
payment in the form of a qualified joint and survivor annuity is not required
with respect to the participant pursuant to section 8.2 of the plan, only the
participant need consent to the distribution of an account balance that is
immediately distributable.) Neither the consent of the participant nor the
participant's spouse shall be required to the extent that a distribution is
required to satisfy section 401(a) (9) or section 415 of the Code. In addition,
upon termination of this plan if the plan does not offer an annuity option
(purchased from a commercial provider) the participant's account balance may,
without the participant's consent, be distributed to the participant or
transferred to another defined contribution plan (other than an employee stock
ownership plan as defined in section 4975(e) (7) of the Code) within the same
controlled group. An account balance is immediately distributable if any part of
the account balance could be distributable to the participant (or surviving
spouse) before the participant attains or would have attained if not deceased)
the later of normal retirement age or age 62. For purposes of determining the
applicability of the foregoing consent requirements to distributions made before
the first day of the first plan year beginning after December 31, 1988, the
participant's vested account balance shall not include amounts attributable to
accumulated deductible employee contributions within the meaning of section
72(0)(5)(B) of the Code.

        8.02
        Qualified Joint and Survivor Annuity and pre-retirement Survivor Annuity

        (a) For purposes of this Article VIII:

                (1) "Qualified Election" means a waiver of a Qualified Joint and
Survivor Annuity or a pre-Retirement Survivor Annuity, as defined under article
8.02(a)(3) and (5) of the Plan. The waiver must be in writing and must be
consented to by the participant's Spouse. The Spouse's consent to a waiver must
be witnessed by a Plan representative or notary public and must be limited to a
benefit for a specific alternate Beneficiary. Notwithstanding this consent
requirement, if the participant established to the satisfaction of a Plan
representative that such written consent may not be obtained because there is no
Spouse or the Spouse cannot be located, a waiver by the participant only will be
deemed a Qualified Election. Any consent necessary under this provision will be
valid only with respect to the Spouse who signs the consent, or in the event of
a deemed Qualified Election, the designated Spouse. Additionally, a revocation
of a prior waiver may be made by a participant without the consent of the Spouse
at any time before the commencement of benefits. However, once made, the consent
of a Participant's Spouse shall 



                                       55
<PAGE>   59

be irrevocable. A participant may make any number of revocations during the
election period. Any new waiver or change of Beneficiary will require new
spousal consent.

                (2) During the 90 day period ending on the annuity starting
date, a participant may waive the Qualified Joint and Survivor Annuity form of
benefit provided the following conditions are satisfied:

                (A) the participant's spouse consents in writing to the election
are the spouse's consent is witnessed by a plan representative or notary public;

                (B) the participant's waiver and the spouse's consent state that
the specific nonspouse beneficiary (including any class of beneficiaries or
contingent beneficiaries) and the particular optional form of benefit, may not
be further modified (except back to a Qualified Joint and Survivor Annuity)
without subsequent spousal consent (unless expressly permitted by the spouse);
and

                (C) The spouses consent acknowledges the effect of the election.
Unless an optional form of benefit is selected pursuant to a qualified election
within a 90-day period ending on the annuity starting date, a married
participant's vested accrued benefit will be paid in the form of a qualified
joint and survivor annuity and an unmarried participant's vested accrued benefit
will be paid in the normal form of an immediate life annuity. The participant
may elect to have such annuity distributed upon attainment of the earliest
retirement age under the Plan.

                (3) "Qualified Joint and Survivor Annuity" means an annuity for
the life of the Participant with a survivor annuity for the life of the Spouse
which is not less than 50 percent and not more than 100 percent of the amount of
the annuity which is payable during the joint lives of the Participant and the
Spouse and which is the amount of benefit which can be purchased with the vested
balance in the Participant's Account. The Joint and 50% Survivor Annuity is
designated as the automatic form of benefit payment.

                (4) "Spouse" means the spouse or surviving spouse of the
Participant, including a former spouse or surviving spouse to the extent
provided under a qualified domestic relations order as described in Section
414(p) of the Code.

                (5) "Pre-retirement survivor annuity" shall mean an annuity
which is purchased for the life of the surviving spouse the actuarial equivalent
of which is not less than 50 percent of the nonforfeitable account balance,
including the proceeds of life insurance on the participant's life, of the
Participant, as of the date of death. No more than a proportional percent of the
account balance attributable to contributions that may not be forfeited at
death, (e.g. employee deferrals) may be used to satisfy this requirement. The
amount of life insurance shall not exceed the Incidental Death Benefits
contained in 9.03 of the plan.

        (b) Notwithstanding any other provision of this Plan to the contrary,
except as provided in Subsection (d) -



                                       56
<PAGE>   60

                (1) If a Participant who completes at least one (1) Hour of
Service on or after August 23, 1984 does not make a Qualified Election and dies
before benefits have commenced as a Qualified Joint and Survivor Annuity, the
Participant's vested Account balance, including life insurance, less any loans
will be distributed in the form of a life annuity; and if a married participant
with vested benefits attributable to employer or employee contributions dies
before the Annuity Starting Date, the participant's spouse will be provided with
a pre-retirement survivor annuity unless there has been a proper election to
waive the pre-retirement survivor annuity and the notice requirements have been
met.

                (2) If a married Participant who completes at least one (1) Hour
of Service on or after August 23, 1984 does not make a Qualified Election and
dies before benefits have begun under the Plan, his Account balance including
life insurance less any loans shall be applied to purchase an annuity for the
surviving Spouse the actuarial equivalent of which is not less than 50% of the
account balance of the participant as of the date of death.

                (3) the surviving spouse may direct the commencement of payments
under the Pre-Retirement Survivor Annuity within a reasonable time after the
participant's death.

        (c)(1)The Trustees shall provide to each Participant within no less
than 30 days and no more than 90 days prior to the annuity starting a written
explanation of (1) the terms and conditions of the Qualified Joint and Survivor
Annuity; (2) the Participant's right to make and the effect of an election to
waive the Qualified Joint and Survivor Annuity; (3) the rights of a
Participant's Spouse; and (4) the right to make and the effect of a revocation
of a previous election to waive the Qualified Joint and Survivor Annuity.
Notwithstanding the other requirements of this section, the respective notices
prescribed by this section need not be given to a participant if (1) the plan
"fully subsides" the costs of a qualified joint and survivor annuity or
qualified preretirement survivor annuity, and (2) the plan does not allow the
participant to waive the qualified joint and survivor annuity or qualified
preretirement survivor annuity and does not allow a married participant to
designate a nonspouse beneficiary. A plan fully subsidizes the costs of a
benefit if no increase in cost, or decrease in benefits to the participant may
result from the participant's failure to elect another benefit.

        (2) The Trustees shall also provide each Participant within the period
beginning on the first day of the Plan Year in which the Participant attains age
32 and ending with the close of the Plan Year preceding the Plan Year in which
the Participant attains age 35, a written explanation of the Pre-Retirement
Survivor Annuity as described in Section 8.02(b) (2) in such terms and in such
manner as would be comparable to the explanation provided for meeting the
requirements of Paragraph (1).

        (3) If a Participant enters the Plan after the first day of the Plan
Year in which age 32 is attained, the Trustees shall provide the required notice
no later than the close of the third Plan Year following the Participant's entry
into the Plan.

        (4) The Trustees shall provide a participant and his spouse, if any,
with a written explanation of a pre-retirement survivor annuity within one year
after the Participant separates from service before age 35 if he has already
received the explanation.



                                       57
<PAGE>   61

        (5) Election Period: The period which begins on the first day of the
plan year in which the participant attains age 35 and ends on the date of the
participant's death. If a participant separates from service prior to the first
day of the plan year in which age 35 is attained, with respect to the account
balance as of the date of separation, the election period shall begin on the
date of separation. Pre-age 35 waiver: A participant who will not yet attain age
35 as of the end of any current plan year may make a special qualified election
to waive the qualified preretirement survivor annuity for the period beginning
on the date of such election and ending on the first day of the plan year in
which the participant will attain age 35. Such election shall not be valid
unless the participant receives a written explanation of the qualified
preretirement survivor annuity. Qualified preretirement survivor annuity
coverage will be automatically reinstated as of the first day of the plan year
in which the participant attains age 35. Any new waiver on or after such date
shall be subject to the full requirement of this Section. Earliest retirement
age shall mean the earliest date under the Plan the Participant could elect to
receive retirement benefits.

        (d) This section shall apply to a participant in a profit sharing plan,
and to any distribution, made on or after the first day of the first plan year
beginning after December 31, 1988, from or under a separate account attributable
solely to accumulated deductible employee contributions, as defined in section
72(o)(5)(B) of the Code, and maintained on behalf of a participant in a money
purchase pension plan, (including a target benefit plan) if the following
conditions are satisfied: (1) the participant does not or cannot elect payments
in the form of a life annuity; and (2) on the death of a participant, the
participant's vested account balance will be paid to the participant's surviving
spouse, but if there is no surviving spouse, or if the surviving spouse has
consented in a manner conforming to a qualified election, then to the
participant's designated beneficiary. The surviving spouse may elect to have
distribution of the vested account balance commence within the 90-day period
following the date of the participant's death. The account balance shall be
adjusted for gains or losses occurring after the participant's death in
accordance with the provisions of the plan governing the adjustment of account
balances for other types of distributions. This section shall not be operative
with respect to a participant in a profit sharing plan if the plan is a direct
or indirect transferee of a defined benefit plan, money purchase plan, a target
benefit plan, stock bonus, or profit sharing plan which is subject to the
survivor annuity requirements of section 401(a)(11) and section 417 of the Code.
The participant may waive the spousal death benefit described in this section at
any time provided that no such waiver shall be effective unless it satisfied the
conditions that would apply to the participant's waiver of the qualified
preretirement survivor annuity. For purposes of this section, vested account
balance shall mean, in the case of a money purchase pension plan or a target
benefit plan, the participant's separate account balance attributable solely to
accumulated deductible employee contributions within the meaning of section
72(o)(5)(B) of the Code. In the case of a profit sharing plan, vested account
balance shall have the same meaning as provided in hereinabove.

        Transitional Rules



                                       58
<PAGE>   62

        (a) Any living Participant who is not receiving benefits on August 23,
1984, and would otherwise not receive the benefits prescribed in Section 8.02
must be given the opportunity to elect to have the provisions of Section 8.02

under this Plan or a predecessor plan in a Plan Year beginning on or after
January 1, 1976 and (2) had at least ten (10) Years of Service when he or she
incurred a Termination of Employment.

        (b) Any living Participant who is not receiving benefits on August 23,
1984, and who was credited with at least one Hour of Service under this Plan or
a predecessor plan on or after September 2, 1974, and who is not otherwise
credited with any service in a Plan Year beginning on or after January 1, 1976,
must be given the opportunity to have his or her benefits paid in accordance

beginning on August 23, 1984, and ending on the date benefits would otherwise
begin.

        (d) Any Participant who has elected pursuant to Subsection (b) and any
Participant who does not elect under Subsection (a) or who meets the
requirements of Subsection (a) except that such Participant does not have at
least ten (10) Years of Service when he or she had a Termination of Employment,
shall have his or her benefits distributed in accordance with all of the
following requirements if benefits would have been payable in the form of a life
annuity:

                (1) Automatic Joint and Survivor Annuity - If benefits in the
form of a life annuity become payable to a married Participant who:

                        (A) begins to receive payments under the Plan on or
after his Normal Retirement Age, or

                        (B) dies on or after Normal Retirement Age while still
working for the Employer; or

                        (C) begins to receive payments on or after the Qualified
Early Retirement Age; or

                        (D) has a Termination of Employment on or after
attaining Normal Retirement Age (or the Qualified Early Retirement Age) and
after satisfying the eligibility requirements for the payment of benefits under
the Plan and thereafter dies before beginning to receive such benefits; then
such benefits will be received under this Plan in the form of a Qualified Joint
and Survivor Annuity, unless the Participant has elected otherwise during the
election period. The election period must begin at least six (6) months before
the Participant attains Qualified Early Retirement Age and end not more than 90
days before the commencement of benefits. Any election will be in writing and
may be changed by the Participant at any time.

                        (E) A Participant who is employed after attaining the
Qualified Early Retirement Age will be given the opportunity to elect, during

                                       59
<PAGE>   63

survivor annuity payable on death. If the Participant elects the survivor
annuity, payments under such annuity must not be less than the payments which
would have been made to the Spouse under the Qualified Joint and Survivor
Annuity if the Participant had retired on the date before his or her death. Any
election under this provision will be in writing and may be changed by the
Participant at any time. The election period begins on the later of (1) the 90th
day before the Participant attains the Qualified Early Retirement Age, or (2)
the date on which participation begins, and ends on the date the Participant has
a Termination of Employment.

        (e) For purposes of this Section 8.03 Qualified Early Retirement Age is
the latest of:

                (1)(A) the earliest date, under the Plan, on which the

                        (B) the first day of the 120th month beginning before
the Participant reaches Normal Retirement Age, or

                        (C) the date the Participant begins participation.

        (2) Qualified Joint and Survivor Annuity is an annuity for the life of
the Participant with a survivor annuity for the life of the Spouse as described
in Section 8.02(a) (6).

        8.04
        Timing of Distributions

        (a) The distribution of a Participant's Account balance (other than
elective contributions see 8.04(g)) under Section 8.01 shall begin at the
Participant's or Beneficiary's election:

                (1) On the earliest practicable date following a Termination of
Employment, if

                        (A) the Participant 5 fully (100%) vested in his or her
Employer contribution Account balance on his Termination of Employment, or

                        (B) the distribution is made in a lump sum and does not
exceed $3,500, or

                        (C) the distribution is made in a lump sum and the
Participant has elected (with his spouse's consent) to receive such
distribution; and

                        (D) distributions shall be made not later than the
required beginning date for distributions.

        (2) On the earliest practicable date after the Allocation Date of the
first Plan Year in which a Participant has a Break in Service, in any case not
specified in Paragraph (1), provided that such Participant consents (and where
applicable obtains his spouse's consent) to receive such distribution on such
date.


                                       60
<PAGE>   64

        (b) In no event, unless a Participant consents to postponement under
Subsection (d), may the distribution of his Account balance commence later than
the sixtieth (60th) day after the last day of the Plan Year in which occurs the
later of (1) a Participant's Normal Retirement Age, or (2) ; the date of his
Termination of Employment.

        (c) The Participant or Beneficiary may elect to defer distributions
under the Plan to the date specified in Section 8.04(a)(2) or to the latest date
specified in Section 8.04(b). Any such deferral of distributions shall be
administered in a uniform and non-discriminatory manner. The employer may not
through the exercise of any discretion, deny a participant a Code Section 4"(d)
(6) protected benefit for which the participant is otherwise eligible.

        (d) A former Participant may consent to postpone the distribution of his
Account balance beyond the latest date permitted by Subsection (b), but in no
event later than April 1st of the calendar year following the year in which age
70-1/2 is attained, by filing a written statement with the Trustees describing
the distribution to which he is entitled and stating the date upon which he
desires such distribution to commence. Any such postponement shall require the
approval of the Trustees.

        (e) For distributions beginning before the participant's death, the
first distribution calendar year is the calendar year immediately preceding the
calendar year which contains the participant's required beginning date. For
distributions beginning after the participant's death, the first distribution
calendar year is the calendar year in which distributions are required to begin.

        (f) If the Plan has early retirement provision and contains either a
minimum age or service for eligibility, a participant who meets the service
requirement, but separates from service before early retirement will begin to
receive benefits, unless otherwise elected upon meeting the early retirement age

        (g) Elective Deferrals may not be distributed earlier than upon one of
the following events:

                (1) The employee's retirement, death, disability or separation
from service;

                (2) The termination of the plan without establishment of a
successor defined contribution plan other than an employee stock ownership plan
(as defined in section 4975(e) or section 409 of the Code) or a simplified
employee pension plan as defined in section 408(k).

                (3) In case of a profit sharing or stock bonus plan, the
employee's attainment of age 59-1/2 or, for plan year beginning before 1989, the
employee's hardship;

                (4) the sale or other disposition by a corporation to an
unrelated corporation of substantially all of the assets used in a trade or
business, but only with respect to employees who continue employment with the
acquiring corporation; and



                                       61
<PAGE>   65

                (5) The sale or other disposition by a corporation of its
interest in a subsidiary to an unrelated entity but only with respect to
employees who continue employment with the subsidiary.

                (6) All distributions that may be made pursuant to one or more
of the foregoing distributable events are subject to the spousal and participant
consent requirements (if applicable) contained in section 4c(a) (11) and 417 of
the Code. In addition, distributions after March 31, 1988, that are triggered by
event (2), (4), or (5) enumerated above must be made in a lump sum.

        (h) The required beginning date of a participant who attains age 70 1/2
before January 1, 1988, shall be determined in accordance with (1) or (2) below:

                (1) Non-5-percent owners. The required beginning date of a
participant who is not a 5-percent owner is the first day of April of the
calendar year following the calendar year in which the later of retirement or
attainment of age 70 1/2 occurs.

                (2) 5-percent owners. The required beginning date of a
participant who is a 5-percent owner during the year beginning after December
31, 1979, is the first day of April following the later of:

                        (i) the calendar year in which the participant attains
age 70 1/2, or

                        (ii) the earlier of the calendar year with or within
which ends the plan year in which the participant becomes a 5-percent owner, or
the calendar year in which the participant retires.

The required beginning date of a participant who is not a 5-percent owner who
attains age 70 1/2 during 1988 and who has not retired as of January 1, 1989, is
April 1, 1990.

        (i) 5-percent owner. A participant is treated as a 5-percent owner for
purposes of this section if such participant is a 5-percent owner as defined in
section 416(i) of the Code (determined in accordance with section 416 but
without regard to whether the plan is top-heavy) at any time during the plan
year ending with or within the calendar year in which such owner attains age 66
1/2 or any subsequent plan year. Once distributions have begun to a 5-percent
owner under this section, they must continue to be distributed, even if the
participant ceases to be a 5-percent owner in a subsequent year.

        8.05
        Repayment of Forfeitures

        (a) A former Participant who again becomes an Employee and satisfies all
of the conditions set forth in this Subsection (a), may repay to the Trust Fund
the amount of any distribution which was received upon the Participant's
previous Termination of Employment. Upon such repayment, the Employer shall
restore the portion of the Participant's Account balance which was forfeited
upon such Termination of Employment, unadjusted for any gains or losses 



                                       62
<PAGE>   66

incurred by the Trust Fund since the Allocation Date as of which the forfeiture
occurred. The right of repayment described in this Subsection (a) shall exist
only if --

                (1) the Participant, following a previous Termination of
Employment, received a distribution in one lump sum;

                (2) upon such Termination of Employment, such Participant was
not fully (100%) vested in his Employer contribution Account balance; and

                (3) such repayment is made before the Participant has incurred
five (5) consecutive one-year Breaks in Service.

        (b) Any restoration of forfeitures under Subsection (a) shall be made
from Employer contributions.

        (c) If a benefit is forfeited because the Participant or beneficiary
cannot be found, such benefit will be reinstated if a claim is made by the
Participant or beneficiary.

        8.06
        Distributions After Death

        (a)(1)In the event a Participant dies before benefits commence and the
Participant has not made a Qualified Election to waive the Pre-Retirement
Annuity, such benefit shall be paid in the form of an immediate or deferred
annuity for the surviving Spouse's lifetime or with the consent of the surviving
Spouse in one lump sum. In the event a surviving Spouse elects to purchase a
deferred annuity, distribution must commence not later than the date on which
the Participant would have attained age 70-1/2. In the event the surviving
Spouse is the Beneficiary and dies before distribution to such Spouse begins,
the surviving Spouse shall be treated as if he or she were the Participant. If a
Participant dies before benefits commence and his surviving Spouse is not the
designated Beneficiary, the entire interest must be distributed within 5 years
after the participant's death to the Participant's Beneficiary or Beneficiaries
unless a designated Beneficiary elects not later than one year following the
Participant's death to receive the distribution over the designated
Beneficiary's lifetime. If distributions have commenced to the Participant
before the Participant's death, the remaining portion of the Participant's
benefit will be paid to the Participant's surviving Spouse or other Beneficiary
as rapidly as under the method selected by the Participant. Any amount paid to a
child of the Participant will be treated as if it had been paid to the surviving
spouse if the amount becomes payable to the surviving spouse when the child
reaches the age of majority. If distribution in the form of an annuity
irrevocably commences to the participant before the required beginning date, the
date distribution is considered to begin is the date distribution actually
commences.

        (2) For purposes of Paragraph (1), payments will be calculated by use of
the return multiples specified in section 1.72-9 of the Income Tax Regulations.
Life expectancy of a surviving spouse may be recalculated annually. In the case
of any other designated Beneficiary, life expectancy will be calculated at the
time payment first commences and payments for any 



                                       63
<PAGE>   67

12-consecutive month period will be based on such life expectancy minus the
number of whole years passed since distribution first commenced.

        (b) Notwithstanding the provisions contained in Subsection (a) and
subject to the requirements contained in Section 8.02(a), a distribution on
behalf of any Employee, including a 5% owner, may be made in accordance with the
following requirements (regardless of when such distribution commences):

                (1) The distribution by the trust is one which would not have
disqualified such trust under Section 401(a)(9) of the Code, as in effect prior
to amendment by the Deficit Reduction Act of 1984.

                (2) The distribution is in accordance with a method of
distribution designated by the Employee whose interest in the trust is being
distributed or, if the Employee is deceased, by a Beneficiary of such Employee.

                (3) Such designation was in writing was signed by the Employee
of the Beneficiary, and was made before January 1, 1984 and was made pursuant to
Section 242(b)(2) of the Tax Equity and Fiscal Responsibility Act of 1982
("TEFRA").

                (4) The Employee had accrued a benefit under the Plan as of
December 31, 1983.

                (5) (A) The method of distribution designated by the Employee of
the Beneficiary specifies the time at which distribution will commence, the
period over which distributions will be made, and in the case of any
distribution upon the Employee's death, the Beneficiaries of the Employee listed
in order of priority.

                        (B) A distribution upon death will not be covered by
this transitional rule unless the information in the designation contains the
required information described above with respect to the distributions to be
made upon the death of the Employee.

                        (C) For any distribution which commences before January
1, 1984, but continues after December 31, 1983, the Employee, or the
Beneficiary, to whom such distribution is being made, will be presumed to have
designated the method of distribution under which the distribution is being made
if the method of distribution was specified in writing and the distribution
satisfies all the applicable requirements described in Paragraphs 1 through 5
above.

                        (D) If a designation is revoked, and subsequent
distribution must satisfy the. requirements of Section 401(a)(9) of the Code
and the proposed regulations thereunder. If a designation is revoked subsequent
to the date distributions are required to begin, the trust must distribute by
the end of the calendar year following the calendar year in which the revocation
occurs the total amount not yet distributed which would have been required to
have been distributed to satisfy section 401(a)(9) of the Code and the proposed
regulations thereunder, but for the section 242(b)(2) election. For calendar
years beginning after December 31, 1988, such distributions must meet the
minimum distribution incidental benefit 



                                       64
<PAGE>   68

requirements in section 1.401(a) (9)-2 of the proposed regulations. Any changes
in the designation will be considered to be a revocation of the designation.
However, the mere substitution or addition of another Beneficiary (one not named
in the designation) under the designation will not be considered to be a
revocation of the designation, so long as such substitution or addition does not
alter the period over which distributions are to be made under the designation,
directly or indirectly (for example, by altering the relevant measuring life) .
In the case in which an amount is transferred or rolled over from one plan to
another plan, the rules in Q & A J-2 and Q & A J-3 shall apply.

        8.07
        Beneficiaries

        (a) Upon receipt of a notification from the Trustees that an individual
has qualified for participation in the Plan, a participant shall designate, on
forms provided for that purpose by the Trustees and the Insurer, if applicable,
a Beneficiary and successor Beneficiary. Such designation shall be subject to
the following rules:

                (1) If the Participant is married, and has not made a Qualified
Election, the Beneficiary shall be his Spouse.

                (2) If the Participant is married, and he revokes a Qualified
Election, the Beneficiary shall be his Spouse.

                (3) If the Participant is not married or is married and has made
a Qualified Election, the Beneficiary of any death benefit under the Plan shall
be his designated Beneficiary.

                (4) If the Participant is married or unmarried and any life
insurance or annuity contract is issued on his life under this Plan, the
Beneficiary of such contract shall be the Trustee(s).

        The designation of a Beneficiary shall be effective upon its receipt in
proper form by the Trustees, or, if applicable, the Insurer.

        (b) The Trustees of the Insurer may prescribe rules and regulations for
changing the Beneficiary. If any Participant fails to designate a Beneficiary or
is predeceased by the designated Beneficiary, the Beneficiary shall be:

                (1) the Participant's Spouse, if married, otherwise

                (2) the Participant's living children (including adoptive
children) in equal shares, otherwise

                (3) The Participant's parents, if living, in equal shares.

        Incompetency



                                       65
<PAGE>   69

        A Participant or Beneficiary may be, in the judgment of the Trustees,
legally, physically or mentally incapable of personally receiving and receipting
for any payment due under this Plan. If so, payment may, in the discretion of
the Trustees, be made to the guardian or legal representative of such
Participant or Beneficiary. If no guardian or representative exists, payment may
be made to any other person or institution which, in the judgment of the
Trustees, then maintains or has custody of, such Participant or Beneficiary.

           ARTICLE IX -- LIFE INSURANCE POLICIES AND ANNUITY CONTRACTS

        9.01
        Purchase of Life Insurance

        The trustees shall apply for and will be owner of any insurance contract
purchased under the terms of this plan. The insurance contract(s) must provide
that proceeds will be payable to the trustee, however the trustee shall be
required to pay over all proceeds of the contract(s) to the participant's
designated beneficiary in accordance with the distribution provisions of this
plan. A participant's spouse will be the designated beneficiary of the proceeds
in all circumstances unless a qualified election has been made with spousal
consent in accordance with Section 8, Joint and Survivor Annuity Requirements,
if applicable. Under no circumstances shall the trust retain any part of the
proceeds. In the event of any conflict between the terms of this plan and the
terms of any insurance contract purchased hereunder, the plan provisions shall
control.

        9.02
        Ownership of Policies and Contracts

        (a) The Trustees shall own all life insurance and annuity contracts
acquired under the Plan and shall be designated as sole owner in each contract
and shall abide by the terms of this plan including the joint and survivor
annuity requirements

        (b) In the event that this Plan substitutes for a previous Plan which
was non-trusteed, any life insurance or annuity contract which was purchased
under such previously existing plan may be kept in force under this Plan even
though it is owned by the Participant and not by the Trustees. Each such
contract shall be non-transferable and must be endorsed to prohibit the owner
from exercising the loan and assignment privileges without the consent of the
Employer.

        (c) In the event that any life insurance contract was purchased under a
pre-existing plan on the life of a Participant, such contract may be maintained
under this Plan (even if not issued by the Insurer) . The only annuity contracts
which may be maintained under this Plan are those which are issued by the
Insurer.

        9.03
        Incidental Death Benefits

        (a) The limitations on the amount of insurance which may be purchased
under the Plan are the portion of Employer contributions and forfeitures
allocated to the Participant's Account for the current and first two (2)
preceding Plan Years used to purchase term or universal life insurance policies,
plus 50% of the portion used to purchase ordinary life insurance and endowment
policies other than retirement income policies, shall at no time exceed 25% of
the portion of such sum not used to purchase retirement income policies. All
amounts allocated prior to the last two Plan Years may be applied to the
purchase of whole life or term insurance. For purposes of these incidental
insurance provisions, ordinary life insurance contracts are contracts with both
nondecreasing death benefits and nonincreasing premiums. If such contracts 



                                       67
<PAGE>   71

are purchased, less than 1/2 of the aggregate employer contributions allocated
to any participant will be used to pay the premiums attributable to them. The
sum of 1/2 of the ordinary life insurance premiums and all other life insurance
premiums will not exceed 1/4 of the aggregate employer contributions and
employee deferrals allocated to any participant.

        (b) As soon as practicable after each Allocation Date, the Trustees
shall recompute the maximum death benefit purchasable in accordance with the
provisions of Section 9.03(a). If upon such recomputation it is determined that
the face amount of the contract(s) on the Participant's life exceeds the maximum
death benefit as so recomputed, or if such Participant shall have modified or
terminated his election, the Trustees shall take such action as may be specified
by the Insurer to adjust the face amount of the contract(s) held for the
Participant so as not to exceed the limitation contained in Section 9.03(a).

        9.04
        Increases and Reductions in Face Amount

        (a) Each policy acquired under this Article IX shall be purchased from
assets of the Account of the Participant on whose life such contract is issued
and shall be an asset of the Trust earmarked for such Participant's Account.

        (b) A Participant who desires to maintain less life insurance under the
Plan than the amount in force may elect to purchase the contract(s) issued on
his life for an amount equal to the net cash value. Alternatively, the Trustees
may borrow out the loan value(s) and sell the contract(s) subject to the loan(s)
to the Participant for the then remaining value. If the Participant does not
elect to make the purchase, the contract(s) will be surrendered.

        9.05
        Application of Dividends

        All dividends or credits earned on insurance contracts will be allocated
to the Account of the Participant on whose life such contract was issued.

        9.06
        Refund of Premiums

        If a premium or the cost of insurance on a life insurance contract Is
waived on account of a Participant's disability, the premium or the cost of
insurance which is returned by the Insurer shall be added to the disabled
Participant's Account.

        9.07
        Distribution of Life Insurance policies

        Life Insurance policies shall be either converted to cash, an annuity
contract, or distributed to the Participant at or before retirement. If the
participant's benefit is distributed in the form of an annuity purchased from an
insurance company, distributions thereunder shall be



                                       68
<PAGE>   72

 made in accordance with the
requirement of section 401(a) (9) of the Code and the proposed regulations
thereunder.

                           ARTICLE X -- MISCELLANEOUS

        10.01
        Non-Alienation and Non-Assignment of Benefits

        (a) No benefit under this Plan shall be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, charge,
encumbrance, garnishment, levy or attachment. Any attempt to anticipate,
alienate, sell, transfer, assign, pledge, charge, encumber, garnish, levy upon
or attach any benefit under this Plan shall be void. No benefit under this Plan
shall be in any manner liable for or subject to the debts, contracts,
liabilities engagements or torts of the person entitled to it.

        (b) The prohibition against assignment and alienation of benefits
contained in Subsection (a) shall not apply to any benefit payable with respect
to a Participant pursuant to a qualified domestic relations order as defined in
Section 414(p) of the Code or pursuant to any domestic relations order if such
order was entered before January 1, 1985.

        10.02
        Amendment to Plan

        (a) The Employer may amend any selection it has made in Article I or
replace this Plan with another program, at any time. Also, no amendment or
replacement of the Plan may change, without the Trustees' written consent, the
duties, responsibilities, rights or privileges of the Trustees under the Plan.

        (b) No amendment or replacement of the Plan may deprive any Participant
of any benefit accrued under the Plan, decrease a Participant's Account balance
or eliminate an optional form of distribution, except for the removal of an
option which does not involve a Participant's "protected benefits" as determined
in accordance with regulations to be prescribed by the Secretary of the
Treasury, except to the extent such amendment is necessary for the Plan to
obtain or retain its qualified status or to conform the Plan to any other law or
regulation which pertains to qualified retirement plans.

        (c) The Employer may amend this Plan if the amendment relates to
administrative provisions of the trust or custodial account document (such as
provisions relating to investments and the duties of trustees), so long as the
amended provisions are not in conflict with any other provisions of the plan and
do not conflict with any other provision of the plan and do not cause the plan
to fail to qualify under section 401(a) of the Code.

        (d) The sponsoring organization may amend any part of the plan. For
purposes of sponsoring organization amendments, the mass submitter shall be
recognized as the agent of the sponsoring organization. If the sponsoring
organization does not adopt the amendments made by the mass submitter, it will
no longer be identical to or a minor modifier of the mass submitter plan. The
employer may (1) change the choice of options in the adoption agreement, (2) add
overriding language in the adoption agreement when such language is necessary to
satisfy section 415 or section 416 of the Code because of the required
aggregation of multiple plans, and 



                                       70
<PAGE>   74

(3) add certain model amendments published by the Internal Revenue Service which
specifically provide that their adoption will not cause the plan to be treated
as individually designed. An employer that amends the plan for any other reason,
including a waiver of the minimum funding requirement under section 412(d) of
the Code, will no longer participate in this regional prototype plan and will be
considered to have an individually designed plan.

        10.03
        Merger or Consolidation

        If this Plan merges or consolidates with, or transfers assets or
liabilities to, any other plan, each Participant in this Plan shall be entitled
to receive a benefit immediately after the merger, consolidation or transfer
(assuming that the Plan had then terminated) which is equal to or greater than
the benefit such Participant would have been entitled to receive immediately
before the merger, consolidation or transfer (assuming that the Plan had then
terminated).

        10.04
        Termination of Plan

        The Employer may terminate the Plan at any time. No benefit shall accrue
to any Participant after such termination. Upon the termination or partial
termination of the Plan, each affected Participant shall be 100% vested in his
Accounts. If this Plan is a Profit Sharing Plan, in the event of a complete
discontinuance of contributions under the Plan, each affected Participant shall
be 100% vested in his Account under such Plan.

        10.05
        Gender and Form

        Wherever any words are used in this Plan in the masculine gender, they
should be considered as if they are also used in the feminine gender, in all
cases where they so apply and vice-versa; and wherever any words are used in
this Plan in a singular form, they should be considered as if they are also used
in a plural form, in all cases where they so apply and vice-versa.

        10.06
        Conditions on Employer Contributions

        (a) The Employer's contribution is conditioned upon the initial
qualification of the Plan under Section 401(a) of the Code. If the Plan fails to
qualify, the Trustees shall within one year after the date initial qualification
is denied, dispose of each contract and liquidate each Account as if the
Participant on whose life such contract was issued or for whom such Account was
established had resigned with a non-forfeitable percentage of zero, and each
Participant's voluntary contributions, if any, plus any gains and less any
losses and expenses attributable thereto, shall be returned to the Participant
who made it. However, if this Plan is being substituted for a previous program,
the Trustees shall dispose of each contract in accordance with non-forfeitable
provisions of this plan. In the event that the Commissioner of the Internal
Revenue determines that the plan is not initially qualified under the Internal
Revenue Code, any 



                                       71
<PAGE>   75

contribution made incident to that initial qualification by the employer must be
returned to the Employer within one year after the date the initial
qualification is denied, but only if the application for the qualification is
made by the time prescribed by law for filing the employer's return for the
taxable year in which the Plan is adopted, or such later year as the Secretary
of the Treasury may prescribe.

        (b) All contributions made by the Employer to the Plan are conditioned
upon their deductibility under Section 404 of the Code. If the deduction for any
contribution is denied, the value of the contribution shall to the extent it is
disallowed be returned to the Employer within one year following the date of
disallowance.

        (c) If any Employer contribution to this Plan is made by a good faith
mistake of fact, the value of the contribution may be returned to the Employer
within one year following the date it is made.

        10.07
        Conflict Between Plan and Contracts

        In the event of a conflict between the provisions of the Plan and any
insurance contract issued under or to the Plan, the provisions of the Plan shall
govern.

        10.08
        Furnishing Information to Participants, Etc.

        (a) The Trustees shall notify all persons who are eligible to
participate in this Plan, informing them of the basic provisions of the Plan and

        (b) The Employer shall require each Participant to take whatever action
may be necessary by such Participant to permit the Administrator, the Trustee,
the Participant and the Insurer to comply, with the laws and regulations
applying to the Plan. The Trustees shall take all necessary steps to carry out
the provisions of the Plan.

        10.09
        Annual Accounting

        The Trustee shall give to the Employer an annual accounting on the basis
of the Plan Year showing receipts and the charges and credits made under the
Plan. Such accounting shall be based upon the current fair market value of the
Trust assets. The value of any insurance or annuity contract shall be determined
in the same way as in Section 4.09(b). The Employer's approval of the Trustee's
accounting will be assumed at the end of 90 days after receipt by the Employer
unless the Trustee is notified otherwise. The Trustee shall also, on request,
provide the Employer with whatever information the Employer deems necessary to
enable it to comply with the reporting and disclosure requirements established
by federal law.



                                       72

        10.10
        Exclusive Benefit

        This Plan has been established for the exclusive benefit of the
Participants and their Beneficiaries. No trust funds shall revert to or be used
by or enjoyed by the Employer, except to the extent provided by Section 10.06.

        10.11
        Hardship Withdrawals

        A Participant may apply in writing to the Plan Administrator for a
hardship withdrawal at any time. The withdrawal must be for an immediate and
heavy financial need of the Participant for which funds are not reasonably
available from other resources of the Participant. Hardship withdrawals are
subject to the spousal consent requirements contained in Sections 401(a)(11) and
417 of the Code. If approved by the Plan Administrator, such withdrawal shall
equal the lesser of (i) the amount required to be distributed to meet the need
created by the hardship, or (ii) the Participant's total accumulated
contributions exclusive of earnings after 1988. The only circumstances which may
warrant approval of a Participant's application for a hardship withdrawal are:

        (a) Medical expenses described in section 213(d) of the Code incurred by
the employee, the employee's spouse, or and dependents of the employee (as
defined in section 152);

        (b) Purchase (excluding mortgage payments) of a principal residence for

        (d) The need to prevent the eviction of the employee from his principal
residence or foreclosure on the mortgage of the employee's principal residence.

        10.12

        The following conditions apply to withdrawals made under Section 10.11:

        (a) A Participant may make only one withdrawal from his Tax Sheltered
Savings Account in any 12-month period.

        (b) Withdrawals pursuant to Section 10." hereof shall be based on the
value of the Participant's Tax Sheltered Savings Account as of the Valuation
Date coincident with or next following the Participant's request.

        (c) Withdrawals shall be made from the investment fund(s) designated by
the Participant in writing on a form supplied by the Plan Administrator.



                                       73
<PAGE>   77

        (d) If a hardship withdrawal is allowed by the Plan Administrator the
withdrawal will be made without forfeiting vested benefits based upon employer
contributions.

        (e) Distribution of Elective Deferrals (and any earnings credited to a
participant's account as of the end of the last Plan Year ending before July 1,
1989) may be made to a participant in the event of hardship.

        10.13
        Hardship Withdrawals Immediate Financial Need

A distribution will be deemed to be necessary to satisfy an immediate and heavy
financial need of an employee if all of the following requirements are
satisfied:

        (a) The distribution is not in excess of the amount of the immediate and
heavy financial need of the employee (including amounts necessary to pay any
federal, state or local income taxes or penalties reasonably anticipated to
result from the distribution),

        (b) The employee has obtained all distributions, other than hardship
distributions, and all nontaxable loans currently available under all plans
maintained by the employer,

        (c) The plan, and all other plans maintained by the employer, provide
that the employee's elective contributions and employee contributions will be
suspended for at least 12 months after receipt of the hardship distribution, and

        (d) The plan, and all other plans maintained by the employer, provide
that the employee may not make elective contributions for the employee's taxable
year immediately following the taxable year of the hardship distribution in
excess of the applicable limit under section 402(g) for such next taxable year
less the amount of such employee's elective contributions for the taxable year
of the hardship distribution.

                       ARTICLE XI -- LOANS TO PARTICIPANTS

        11.01
        Loans from the Plan

        Any Participant or beneficiary may apply to the Plan Administrator for a
loan from the Plan. All such loans are available to Participants and
beneficiaries on the same basis with no special treatment of favoritism shown to
officers, stockholders, or highly compensated employees. The Plan Administrator
can establish the policy of denying loans to all Participants and/or
beneficiaries. No loans will be made to any share-holder employee or
owner-employee. For purposes of this requirement, a share-holder employee means
an employee or officer of an electing small business (Subchapter S) corporation
who owns (or is consider as owning within the meaning of section 318 (a) (1) of
the Code, on any day during the taxable year of such corporation, more than 5%
of the outstanding stock of the corporation.

        11.02
        Amount of Loan

        Participant loans, including all Plans of the Employer, are limited to
an amount not to exceed the lesser of:

        a)     50% of the Participant's accrued vested benefit; or
        b)     $50,000.

        The $50,000 limitation is reduced by the highest outstanding loan
balance during the previous twelve (12) months.

        11.03
        Term of Loan

        The maximum term for a Participant loan is five (5) years unless the
purpose of the loan is for the purchase of a dwelling to be used as principal
residence of the Participant ("home loan").

        11.04
        Spousal Consent

        A participant must obtain the consent of his or her spouse, if any, to
use of the account balance as security for the loan. Spousal consent shall be
obtained no earlier than the beginning of the 90-day period that ends on the
date on which the loan is to be so secured. The consent must be in writing, must
acknowledge the effect of the loan, and must be witnessed by a plan
representative or notary public. Such consent shall thereafter be binding with
respect to the consenting spouse or any subsequent spouse with respect to that
loan. A new consent shall be required if the account balance is used for
renegotiation, extension, renewal, or other revision of the loan. If a valid
spousal consent has been obtained, then, notwithstanding any other provision of
this plan, the portion of the participant's vested account balance used as a
security interest held 



                                       75
<PAGE>   79

by the plan by reason of a loan outstanding to the participant shall be taken
into account for purposes of determining the amount of the account balance
payable at the time of death or distribution, but only if the reduction is used
as repayment of the loan. If less than 100% of the participant's vested account
balance (determined without regard to the preceding sentence) is payable to the
surviving spouse, then the account balance shall be adjusted by first reducing
the vested account balance by the amount of the security used as repayment of
the loan, and then determining the benefit payable to the surviving spouse.

        11.05
        Security

        All Participant loans must be secured, in writing, by no more than one
half of the non-forfeitable amount of the Participant's accrued vested benefit.
When the Participant terminates employment with the Employer, dies, or becomes
disabled, any unpaid portion of the loan will be subtracted from the amount of
any distribution due the Participant from the Plan.

        11.06
        Rate of Interest

        All Participant loans will bear a rate of interest equal to 1% above the
current Bank of America's Prime Lending Rate in force at the time such loan is
transacted.

        11.07
        Repayment of Loan

        Generally, all loans must be repaid within five (5) years from the date
the loan is approved with the outstanding balance due at maturity. The only
exception to this general rule is "home loans" which may be written for a
reasonable term, exceeding five years. Participants will be required to make
fully amortized payments at least on a quarterly basis.

        11.08
        Default on Payments

        Participant loans will be subject to demand in the event of default or
foreclosure, but attachment of security will not occur until a distributable
event occurs in the Plan.

        "Default" is defined as follows:

        a) Failure to make a payment when due (or within ten (10) days
thereafter).

        b) Another note of Borrower to Lender becomes or is declared to be due
and payable prior to its maturity.

        c) Property pledged as security has become subject to attachment or
garnishment, or has been disposed of without provision of satisfactory
substitute.



                                       76
<PAGE>   80

        d) Borrower seeks relief from claims of creditors by invoking the
provisions of the federal Bankruptcy Code or state law.

        e) Borrower is subject to bankruptcy, insolvency or other similar
proceeding started by another, consents to, or approves of any such proceeding,
or a receiver is appointed with respect to the Borrower.

        11.09
        Late Payments

        Should an installment payment not be received within ten (10) days of
the due date, the Participant will be charged a late fee of $10.00. If the late
fees have not been paid by the maturity date of the note (or such earlier time
as demand for the balance is made), the outstanding charges will be withdrawn
from the Participant's account balance.

        11.10
        Interest Credited

        Participant loans are deemed to be investments made solely for the
benefit of the account of the Participant under the Plan. Thus, all interest
paid with respect to any Participant loan is credited to the account of the
Borrower, and any loss or other expense associated with any such loan is borne
by the account of the Borrower.

        11.11
        Death of Participant

        In the event of the Participant's death prior to the complete repayment
of this loan, including principal and accrued interest, the Administrator is
directed to distribute the Note evidencing this loan to the Beneficiary(ies)
designated by the Participant under the terms of the Plan and Trust Agreement(s)
covering the Participant's account, and, in the absence of such designation,
then pursuant to the laws of intestacy of the State of California. Under no
circumstances will the Administrator be required to make a creditor's claim
against the Participant's estate for the payment of this loan. Should the
Participant's death necessitate such a claim, it shall be prosecuted, if at all,
by the Participant's Beneficiary(ies) either directly or on behalf of the
Administrator as permitted by the applicable probate procedure. All reasonable
costs and expenses relating to such claim will be borne by the account of the
Participant.

        11.12
        Loan Request

        A Participant or beneficiary must complete and return Participant Loan
Application to the Plan Administrator, so that a determination can be made as to
the requested Participant loan.

        Existing Balances

<PAGE>   81

        No loan to any participant or beneficiary can be made to the extent that
such loan when added to the outstanding balance of all other loans to the
participant or beneficiary would exceed the lesser of (a) $50,000 reduced by the
excess (if any) of the highest outstanding balance of loans during the one year
period ending on the day before the loan is made, over the outstanding balance
of loans from the plan on the date the loan is made, or (b) one-half the present
value of the nonforfeitable accrued benefit of the participant or, if greater,
the total accrued benefit up to $10,000. For the purpose of the above
limitation, all loans from all plans of the employer and other members of a
group of employers described in section 414(b), 414(c), and 414(m) and (o) of
the Code are aggregated. Furthermore, any loan shall by its terms require that
repayment (principal and interest) be amortized in level payments, not less
frequently than quarterly, over a period not extending beyond five years from
the date of the loan, unless such loan is used to acquire a dwelling unit which
within a reasonable time (determined at the time the loan is made) will be used
as the principal residence of the participant. An assignment or pledge of any
portion of the participant's interest in the plan and a loan, pledge, or
assignment with respect to any insurance contract purchased under the plan, will
be treated as a loan under this paragraph.

    ARTICLE XIII-LIMITATIONS ON EMPLOYEE CONTRIBUTIONS AND MATCHING EMPLOYER
                                  CONTRIBUTIONS

        13.01
        Contribution Percentage

        (a) The Average Contribution Percentage for Eligible Participants who
are Highly Compensated Employees for the Plan Year shall not exceed the Average
Contribution Percentage for Eligible Participants who are Non-highly Compensated
Employees for the Plan Year multiplied by 1.25; or

        (b) The Average Contribution Percentage for Eligible Participants who
are Highly Compensated Employees for the Plan Year shall not exceed the Average
Contribution Percentage for Eligible Participants who are Non-Highly Compensated
Employees for the Plan Year multiplied by 2, provided that the Average
Contribution Percentage for Eligible Participants who are Highly Compensated
Employees does not exceed the Average Contribution Percentage for Eligible
Participants who are Non-Highly Compensated Employees by more than two (2)
percentage points or such lesser amount as the Secretary of the Treasury shall
prescribe to prevent the multiple use of this alternative limitation with
respect to any Highly Compensated Employee.

        13.02
        Definitions

For purposes of this Article XIII, and for purposes of Article XVI of this Plan,
the following definitions shall apply.

        (a) "Average Contribution Percentage", "ACP" shall mean the average
(expressed as a percentage) of the Contribution Percentages of the Eligible
Participants in a group. The plan shall take into account the actual
contribution ratios of all eligible employees for the purpose of determining the
actual contribution percentage

        (b) "Contribution Percentage" shall mean the ratio (expressed as a
percentage) of the sum of the Employee Contributions and Matching Contributions
under the plan on behalf of the Eligible Participant for the Plan Year to the
Eligible Participant's Compensation for the Plan Year. An Eligible Employee who
makes no employee contributions and who receives no matching contributions shall
have a contribution ratio that is to be included in determining the ACP of zero.
Such Contribution Percentage Amounts shall not include Matching Contributions
that are forfeited either to correct Excess Aggregate Contributions or because
the contributions to which they relate are Excess Deferrals, Excess
Contributions, or Excess Aggregate Contributions

        (c) "Eligible Participant" shall mean any employee who is eligible to
make an Employee Contribution, or an Elective Deferral (if the employer takes
such contributions into account in the calculation of the Contribution
Percentage), or to receive a Matching Contribution (including forfeitures) or a
Qualified Matching Contribution. If an Employee Contribution is required as a
condition of participation in the plan, any employee who would be a participant
in 



                                       85
<PAGE>   89

the plan if such employee made such a contribution shall be treated as an
eligible participant on behalf of whom no Employee Contributions are made.

        13.03
        Special Rules

        (a) For purposes of this Article XIII, the Contribution Percentage for
any Eligible Participant who is a Highly Compensated Employee for the Plan Year
and who is eligible to make Employee Contributions, or to receive Matching
Contributions or Elective Deferrals allocated to his account under two or more
plans described in Section 401(a) of the Code or arrangements described in
Section 401(k) of the Code that are maintained by the Employer or an Affiliated
Employer shall be determined as if all such contributions and Elective Deferrals
were made under a single plan and if those plans have different plan years then
all such Plans whose limitation year ends with or within the same calendar year
shall be treated as a single arrangement. Notwithstanding the foregoing, certain
plans shall be treated as separate if mandatorily desegregated under regulations
under section 401(m) of the Code. Family members, with respect to Highly
Compensated Employees, shall be disregarded as separate employees in determining
the Contribution Percentage both for participants who are Non-highly Compensated
Employee and for participants who are Highly Compensated Employees.

        (b) All employee deferrals and matching contributions that are made
under two or more plans that are aggregated for purposes of section 401(a) (4)
and 410(b) (other than section 410(b)(2)(A)(ii)) are to be treated as made under
a single plan for the purposes of determining whether the plan satisfies the
actual contribution percentage test of IRC section 401(m). If two or more plans
are permissively aggregated for purposes of section 401(m), the aggregated plans
must also satisfy section 401(a) (4) and 410(b) as though they were a single
plan, but for plan years beginning after December 31, 1989, plans may be
aggregated only if the plans have the same Plan Year.

        (c) A Highly compensated Employee who is either a 5% owner or one of the
ten most highly compensated employees and is therefore subject to the family
aggregation rules of IRC section 414(q)(6), the actual contribution ratio (ACR)
for the family group (which is treated as one highly compensated employee) shall
be the greater of (1) the ACR determined by combining the contributions and
compensation of all eligible family members who are highly compensated without
regards to family aggregation, and (2) the ACR (actual contribution ratio)
determined by combining the contributions and compensation of all eligible
family members. Except to the extent taken into account in the preceding
sentence, the contributions and compensation of all family members are to be
disregarded in determining the actual contribution percentages for the groups of
highly compensated employees and nonhighly compensated employees.

        (d) The determination and treatment of the Contribution Percentage of
any Participant shall satisfy such other requirements as may be prescribed by
the Secretary of the Treasury.

        (e) In calculating the actual contribution percentage (ACP) test of
section 401(m) for a plan year, contributions will be taken into account as
follows: An employee deferral is to be taken into account if it is paid to the
trust during the plan year or paid to an agent of the plan and 



                                       86
<PAGE>   90

transmitted to the trust within a reasonable period after the end of the plan
year. An excess contribution to a cash or deferred arrangement that is
recharacterized is to be taken into account in the plan year in which the
contribution would be have been received in cash by the employee had the
employee not elected to defer the amounts. A matching contribution shall be
taken into account for a plan year only if it is (1) made on account of the
employee's elective or employee contributions for the plan year, (2) allocated
to the employee's account as of a date within that year, and (3) paid to the
trust by the end of the twelfth month following the close of that year.
Qualified matching contributions which are used to meet the requirements of Code
Section 401(k) (3) (A) are not to be taken into account for purposes of the ACP
test of Code Section 401(m).

        (f) For purposes of determining the Contribution Percentage of an
Eligible Participant who is a Highly Compensated Employee, the Employee
Contributions, matching Employer Contributions, qualified nonelective
contributions, and Compensation of such Participant shall include the Employee
Contributions, Matching Contributions, qualified nonelective contributions, and
Compensation of Family Members, and such Family Members shall be disregarded in
determining the Contribution Percentage for Eligible Participants who are
Nonhighly Compensated Employees. For purposes of determining in Contribution
Percentage test, Employee Contributions are considered to have been made in the
Plan Year in which contributed to the trust. Matching Contributions and
Qualified Non-elective Contributions will be considered made for a Plan Year if
made no later than the end of the twelve-month period beginning on the day after
the close of the Plan Year.

        (g) A separate account must be maintained for each participant's
matching contributions as described in Code Section 401(m) (4) (A), that are
not used to satisfy the test provided in Code Section 401(k) (3).

        (h) The employer shall maintain records sufficient to demonstrate
satisfaction of the ACP test and the amount of Qualified Non-elective
Contributions or Qualified Matching Contributions, or both, used in such test.

        (i) If one or more Highly Compensated Employees participate in both a
CODA and a plan subject to the ACP test maintained by the employer and the sum
of the ADP and ACP of those Highly Compensated Employees subject to either or
both test exceeds the Aggregate limit, then the ACP of those Highly Compensated
Employees who also participate in a CODA will be reduced (beginning with such
Highly compensated Employee whose ACP is the highest) so that the limit is not
exceeded. The amount by which each highly Compensated Employee's Contribution
Percentage Amounts is reduced shall be treated as an Excess Aggregate
Contribution. The ADP and ACP of the Highly Compensated Employees are determined
after any corrections required to meet the ADP and ACP tests. Multiple use does
not occur if either the ADP or ACP of the Highly Compensated Employees does not
exceed 1.25 multiplied by the ADP and ACP of the Non-highly Compensated
Employees. "Aggregate Limit" shall mean the sum of (i) 125 percent of the
greater of the ADP of the Non-highly Compensated Employees for the Plan Year or
the ACP of Non-highly Compensated Employees under the plan subject to Code
section 401(m) for the Plan Year beginning with or within the Plan Year of the
CODA and 



                                       87
<PAGE>   91

(ii) the lesser of 200% or two plus the lesser of such ADP or ACP.
"Lesser" is substituted for "greater" in "(i)", above, and "greater" is
substituted for "lesser" after "two plus the" in "(ii)" if it would result in a
larger Aggregate Limit.

              ARTICLE XIV-DISTRIBUTION OF EXCESS ELECTIVE DEFERRALS

        14.01
        In General

        Notwithstanding any other provision of the plan, Excess Deferral Amounts
and income allocable thereto shall be distributed no later than April 15, 1988
and each April 15 thereafter to Participants who claim such Allocable Excess
Deferral Amounts for the preceding calendar year. "Elective Deferrals" shall
mean any employer contributions made to the plan at the election of the
participant, in lieu of cash compensation, and shall include contributions made
pursuant to a salary reduction agreement or other deferral mechanism. With
respect to any taxable year, a participant's Elective Deferral is the sum of all
Employer contributions made on behalf of such participant pursuant to an
election to defer under any qualified CODA as described in section 401(k) of the
Code, any simplified employee pension cash or deferred arrangement as described
in section 402(h)(l)(B), any eligible deferred compensation plan under section
457, any plan as described under section 501(c)(18), and any employer
contributions made on the behalf of a participant for the purchase of any
annuity contract under section 403(b) pursuant to a salary reduction agreement.
Elective Deferrals shall not include any deferrals properly distributed as
excess annual additions.

        14.02
        Definitions

        For purposes of this Plan, the "Excess Elective Deferrals" shall mean
Elective Deferrals that are includable in a participant's gross income under
section 402(g) of the Code to the extent such participant's Elective Deferrals
for a taxable year exceed the dollar limitation under such Code Section. Excess
Elective Deferrals shall be treated as annual additions under the plan, unless
such amounts are distributed no later than the first April 15 following the
close of the participant's taxable year. Excess Elective Deferrals shall be
adjusted for any income or loss up to the date of distribution. The income or
loss allocable to Excess Elective Deferrals is the sum of: (1) income or loss
allocable to the participant's Elective Deferral account for the taxable year
multiplies by a fraction, the numerator of which is such participant's Excess
Elective Deferrals for the year and the denominator is the participant's account
balance attributable to Elective Deferrals with regard to any income or loss
occurring during such taxable year; and (2) ten percent of the amount determined
under (1) multiplied by the number of whole calendar months between the end of
the participant's taxable year and the date of distribution, counting the month
of distribution if distribution occurs after the 15th of such month.

        14.03
        Claims

        A mechanism must be provided by which a participant may notify or be
deemed to notify the Plan Administrator of Excess Elective Deferrals, and if in
writing it shall be submitted to the plan administrator no later than March 1;
shall specify the Participant's Excess Deferral Amount for the Preceding
calendar year; and shall be accompanied by the Participant's written statement
that if such amounts are not distributed, such Excess Deferral Amount, when
added to amounts 



                                       89
<PAGE>   93

deferred under other plans or arrangements described in Sections 401(k), 408(k)
or 403(b) of the Code, exceeds the limit imposed on the Participant by Section
402(g) of the Code for the year in which the deferral occurred.

        Deemed notification occurs if Excess Elective Deferrals arise solely
from Elective Deferrals made under the plan or plans of this employer. A
participant is deemed to notify the Plan Administrator of any Excess Elective
Deferrals that arise by taking into account only those Elective Deferrals made
to this plan and any other plans of this employer.

        14.04
        Maximum Distribution Amount

        Excess Deferral Amount distributed to a Participant with respect to a
calendar year shall be adjusted for income and , if there is a loss allocable to
the Excess Deferral, shall in no event be less than the lesser of the
Participant's account under or the Participant's Elective Deferrals for the Plan
Year.

               ARTICLE XV -- DISTRIBUTION OF EXCESS CONTRIBUTIONS

        15.01
        In General

        Notwithstanding any other provision of the plan, Excess Contributions
and income allocable thereto shall be distributed no later than the last day of
each plan year beginning after December 31, 1987, to Participants on whose
behalf such Excess Contributions were made for the preceding Plan Year.

        15.02
        Excess Contributions

        "Excess Contributions" shall mean the amount of deferred contributions
described in Code Section 401(k) (3) (B) made by Highly Compensated Employees
which cause the plan to fail the annual contribution percentages test of Article
13.01 of this plan. Excess Contributions of participants who are subject to the
family member aggregation rules shall be allocated among the family members in
proportion to the Elective Deferrals (and amounts treated as Elective Deferrals)
of each family member that is combined to determine the combined ADP.

        15.03
        Allocable Income for the Plan Year

        Excess Contributions shall be adjusted for any income or loss up to the
date of distribution. The income or loss allocable to Excess Contributions is
the sum of: (1) income or loss allocable to the participant's Elective Deferral
account (and, if applicable, the Qualified Non-elective Contribution account or
the Qualified Matching Contributions account or both) for the Plan Year
multiplied by a fraction, the numerator of which is such participant's Excess
Contributions for the year and the denominator is the Participant's account
balance attributable to Elective Deferrals (and Qualified Non-Elective
Contributions or Qualified Matching Contributions, or both, if any of such
contributions are included in the ADP test) without regard to any income or loss
occurring during such Plan Year; and (2) ten percent of the amount determined
under (1) multiplied by the number of whole calendar months between the end of
the Plan Year and the date of distribution, counting the month of distribution
if distribution occurs after the 15th of such month.

        15.04
        Maximum Distribution Amount

        The Excess Contributions which would otherwise be distributed to the
Participant shall be adjusted for income and reduced (in accordance with IRS
regulations) by the amount of Excess Deferrals distributed to the Participant.
If there is a loss allocable to the Excess Contributions, it shall in no event
be less than the lesser of the Participant's account under the plan or the
Participant's Elective Deferrals and Qualified Employer Deferral Contributions
for the Plan Year.



                                       91
<PAGE>   95

        15.05
        Accounting for Excess Contributions

        Excess Contributions shall be distributed from the participant's
Elective Deferral account and Qualified Matching Contribution account (if
applicable) in proportion to the participant's Elective Deferrals and Qualified
Matching Contributions (to the extent used in the ADP test) for the Plan Year.
Excess Contributions shall be distributed from the participant's Qualified
Non-elective Contribution account only to the extent that such Excess
Contributions exceed the balance in the participant's Elective Deferral account
and Qualified Matching Contribution account.

        "Excess Contributions" shall mean with respect to any Plan Year, the
excess of the aggregate amount of employer contributions actually taken into
account in computing the ADP of Highly Compensated Employees for such Plan Year,
over, the maximum amount of such contributions permitted by the ADP test
(determined by reducing contributions made on behalf of Highly Compensated
Employees in order of the ADPs, beginning with the highest of such percentages).

        15.06
        Family Aggregation Rules

        In the case of a highly compensated employee whose actual deferral ratio
(ADR) is determined under the family aggregation rules, the determination of the
amount of excess contributions shall be made as follows:

        (a) If the highly compensated employee's ADR is determined by combining
the contributions and compensation of only those family members who are highly
compensated without regard to family aggregations, then the ADR is reduced in
accordance with the "leveling" method described in section l.401(k)-l(f) (2) of
the regulations and the excess contributions for the family unit are allocated
among the family members in proportion to the contributions and compensation of
each family member that have been combined.

        (b) If the highly compensated employee's ADR is determined by combining
the contributions and compensation of all family members, then the ADR is
reduced in accordance with the leveling method but not below the ADR of eligible
non-highly compensated family members. Excess contributions are determined by
taking into account the contributions of the eligible family members who are
highly compensated without regard to family aggregation and are then allocated
among such family members in proportion to their contributions. If further
reductions of the ADR are required, excess aggregate contributions resulting
from this reduction are determined by taking into account the contributions of
all eligible family members and are allocated in the amount to each family
member in proportion to their contribution.

        (c) In the case of a highly compensated employee whose actual deferral
ratio (ADR) is determined under the family aggregation rules, the determination
of the amount of excess contributions shall be made as follows: The ADR is
reduced in accordance with the "leveling" method described in section
l.401(k)-l(f) (2) of the regulations and the excess contributions are 



                                       92
<PAGE>   96

allocated among the family members in proportion to the contributions of each
family member that have been combined.

        (d) The amount of excess contributions for a highly compensated employee
will be determined in the following manner. First, the actual deferral ratio
(ADR) of the highly compensated employee with the highest ADR is reduced to the
extent necessary to satisfy the actual deferral percentage (ADP) test or cause
such ratio to equal the ADR of the highly compensated employee with the next
highest ratio. Second, this process is repeated until the ADP test is satisfied.
The amount of excess contributions for a highly compensated employee is then
equal to the total of elective and other contributions taken into account for
the ADP test minus the product of the employee's contribution ratio as
determined above and the employee's compensation.

        (e) The amount of excess contributions to be distributed shall be
reduced by excess deferrals previously distributed for the taxable year ending
in the same plan year and excess deferrals to be distributed for a taxable year
will be reduced by excess contributions previously distributed for the plan
beginning in such taxable year.

        15.07
        Correction of Excess Deferrals

        (a) The amount of excess deferrals for a highly compensated employee for
a plan year is the amount (if any) by which the employee's elective contribution
must be reduced for the employee's actual deferral ratio to equal the highest
permitted ratio under the plan. To calculate the highest permitted actual
deferral ratio (ADR) under the plan, the (ADR) of the highly compensated
employee with the highest (ADR) is reduced by the amount required to cause the
employee's (ADR) to equal the ratio of the highly compensated employee with the
next highest (ADR). If a lesser reduction would enable the arrangement to
satisfy the actual deferral percentage (ADP) test, only this lesser reduction
may be made. This process must be repeated until the cash or deferred
arrangement satisfies the (ADP) test. The highest (ADR) remaining under the plan
after leveling shall be the highest permitted (ADR). In no case may the amount
of excess deferrals be distributed for the plan year with respect to any highly
compensated employee, exceed the amount of elective contributions made on behalf
of the highly compensated employee for the plan year.

        (b) The amount of excess contributions to be distributed shall be
reduced by excess deferrals previously distributed for the taxable year ending
in the same plan year, and excess deferrals to be distributed for a taxable year
will be reduced by excess contributions previously distributed for the plan
beginning in such taxable year.

        15.08
        Failure to Correct Excess Contribution

        Failure to correct excess contributions by the close of the plan year
following the plan year for which they were made will cause the cash or deferred
arrangement to fail to satisfy the requirements of Code section 401(k) (3) for
the plan year for which the excess contributions were 



                                       93
<PAGE>   97

made and for all subsequent years they remain in the trust. Also, the employer
will be liable for a 10% excise tax on the amount of excess contributions and
any excess aggregate contributions unless they are corrected within 2 1/2 months
after the close of the plan year for which they were made.

        15.09
        Record Keeping

        The Trustee shall correct excess contributions by distributions to
highly compensated employee(s). Records shall be kept by the Employer that
demonstrate compliance with the nondiscrimination requirements of Code Section
401(k) including the extent to which qualified nonelective contributions and
qualified matching contributions are taken into account.

        15.10
        Non-Elective and Matching Contributions

        (a) Non-elective contributions and/or matching contributions may be
treated as elective contributions only if each of the following applicable
conditions are satisfied:

                (1) The amount of nonelective contributions, including those
qualified nonelective contributions treated as elective contributions for the
purposes of the actual deferral percentage test, satisfies the requirements of
section 401(a) (4).

                (2) The amount of nonelective contributions, excluding those
qualified nonelective contributions treated as elective contributions for
purposes of the actual deferral percentage test and those qualified nonelective
contributions treated as matching contributions under Section l.401(m)-l(b) (5)
for purposes of the actual contribution percentage test, satisfies the
requirements of section 401(a)(4).

                (3) For plan years beginning before January 1, 1987, or such
later date provided in Treasury Regulation l.401(k)-l(h), the matching
contributions, including those qualified matching contributions treated as
elective contributions for purposes of the actual deferral percentage test,
satisfy the requirements of section 401 (a) (4).

                (4) For plan years beginning before January 1, 1987, or such
later date provided in Treasury Regulation 4.101(k)-l(h), the matching
contributions excluding those matching contributions treated as elective
contributions for purposes of the actual deferral percentage test, satisfy the
requirements of section 401 (a) (4).

                (5) The qualified nonelective contributions and qualified
matching contributions satisfy the requirements of this section for the plan
year as if the contributions were elective contributions.

                (6) For plan years beginning after December 31, 1988, or such
later date provided in Treasury Regulation l.401(k)-l(h), the plan that includes
the cash or deferred arrangement and the plan or plans to which the 
nonelective contributions and qualified 



                                       94
<PAGE>   98

matching contributions are made, could be aggregated for purposes of section
410(b) (other than the average benefit percentage test). If the plan year of the
plan that includes the cash or deferred arrangement is changes to satisfy the
requirement under section 410(b) that aggregated plans have the same plan year,
the qualified nonelective contributions and qualified matching contributions may
be taken into account in the resulting short plan year only if the contributions
satisfy the requirements of paragraph (b) (4) (i) of this section with respect
to the short year as if the contributions were elective contributions and the
aggregated plans could otherwise be aggregated for purposes of section 410(b) of
the Code.

        (b) Non-elective contributions and matching contributions may be treated
as elective contributions for purposes of the actual deferral percentage test of
section 401(k) only if such contributions are nonforfeitable when made and
subject to the same distributions restrictions that apply to elective
contributions. Non-elective contributions and matching contributions which may
be treated as elective contributions must satisfy these requirements without
regard to whether they are actually taken into account as elective
contributions.

          ARTICLE XVI -- DISTRIBUTION OF EXCESS AGGREGATE CONTRIBUTIONS

        16.01
        In General

        Excess Aggregate Contributions, Matching Contributions, and income
allocable thereto, are corrected by distributing such excess aggregate and
matching contributions and allocable income as designated by the employer as a
distribution of excess aggregate contributions, matching, (and income) and
distributing the funds to the appropriate highly compensated employees after the
close of the plan year in which the excess aggregate contributions arose and
within twelve months after the close of the following plan year. In the event of
the complete termination of the plan during the plan year in which an excess
aggregate contributions arose, such distributions are to be made after
termination of the plan and before the close of the twelve-month period
immediately following such termination.

        16.02
        Excess Aggregate Contributions

        For purposes of this Plan "Excess Aggregate Contributions" shall mean
with respect to any plan year, the excess of:

        (a) the aggregate amount of the matching contributions and employee
elective contributions (and any qualified nonelective contribution or elective
contribution taken into account in computing the contribution percentage)
actually made on behalf of highly compensated employees for such plan year, over

        (b) the maximum amount of such contributions permitted under the
limitations of (determined by reducing contributions made on behalf of highly
compensated employees in order of their contribution percentages beginning with
the highest of such percentages).

        (c) The determination of the amount of excess aggregate contributions
shall be made after first determining the excess deferrals within the meaning of
Code Section 402(g) and then determining the excess contributions under Code
Section 401(k).

        16.03
        Income Allocable to Excess Contributions

        Excess Aggregate Contributions shall be adjusted for any income or loss
up to the date of distribution. The income or loss allocable to Excess Aggregate
Contributions is the sum of: (1) income or loss allocable to the participant's
Employee Contribution account, Matching Contribution account, Qualified Matching
Contribution account (if any, and if all amounts therein are not used in the ADP
test) and, if applicable, Qualified Non-elective Contribution account and
Elective Deferral account for the Plan Year multiplied by a fraction, the
numerator of which is such participant's Excess Aggregate Contributions for the
year and the denominator is the participant's account balance(s) attributable to
Contribution Percentage Amounts without 



                                       96
<PAGE>   100

regard to any income or loss occurring during such Plan Year; and (2) ten
percent of the amount determined under (1) multiplied by the number of whole
calendar months between the end of the Plan Year and the date of distribution,
counting the month of distribution if distribution occurs after the 15th of such
month.

        16.04
        Distribution Amount

        The Excess Aggregate Contributions to be distributed to a Participant
shall be adjusted for income, and, if there is a loss allocable to the Excess
Aggregate Contribution, shall in no event be less than the lesser of the
Participant's account under the plan or the Participant's Employee Contributions
and Matching Contributions for the Plan Year. The Excess Aggregate Contribution
to be distributed shall start at the last dollar contributed and any matching
related to that last dollar. Employee contributions that exceed the matching
limit of the employer shall be distributed first for any highly compensated
employee who's contribution percentage is the highest and then pro-rata for all
highly compensated employees unless one highly compensated employee voluntarily
agrees to take an additional excess aggregate contribution. Any distributions or
forfeitures of excess aggregate contributions for any plan year shall be made on
the basis of the respective portions of such amounts attributable to each highly
compensated employee.

        16.05
        Allocation of Excess Aggregate Contributions

        Notwithstanding any other provision of this plan, Excess Aggregate
Contributions plus any income and minus any loss allocable thereto, shall be
forfeited, if forfeitable, or if not forfeitable, distributed no later than the
last day of each Plan Year to participants to whose accounts such Excess
Aggregate Contributions were allocated for the preceding Plan Year.

        16.06
        Allocation of Forfeitures

        Amounts forfeited by Highly Compensated Employees under this Article XVI
shall be:

        (a) Treated as Annual Additions;

        (b) Applied to reduce employer contributions; and

        (c) Notwithstanding the foregoing, no forfeitures arising under this
Article shall be allocated to the account of any Highly Compensated Employee.

        16.07
        Correction of Excess Contribution

        If there are excess contributions by the highly compensated employees
and the nonhighly compensated employees contributions are not increased to bring
up their ratios then the amount 



                                       97
<PAGE>   101

of excess aggregate contributions which shall include income allocable thereto
from the time of the excess contribution to the time of the distribution of the
excess aggregate contribution for a highly compensated employee under the
requirements of Code Section 401(m) will be corrected in the following manner.
First, the actual contribution ratio (ACR) of the highly compensated employee
with the highest ACR is reduced to the extent necessary to satisfy the Actual
Contribution Percentage (ACP) test or cause such ratio to equal the ACR of the
highly compensated employee with the next highest ratio. Second, this process is
repeated until the ACP test is satisfied. The amount of excess aggregate
contributions for a highly compensated employee is then equal to the total of
employee matching and other contributions taken into account for the ACP test
minus the product of the employee's contribution ratio as determined above and
the employee's compensation. This correction is set out in regulations of the
Department of the Treasury section 401(m)-l(e).

        16.08
        Family Aggregation Rules

        (a) The amount of excess aggregate contributions in the case of a highly
compensated employee's ACP or a highly compensated employee's ACR which has been
determined under the family aggregation rules shall be determined as follows:

                (1) If the highly compensated employee's ACR is determined by
combining the contributions and compensation of only those family members who
are highly compensated without regard to family aggregation, then the ACR is
reduced by reducing the actual contribution ratio and allocating the excess
aggregate contributions for the family group among the family members in
proportion to the employee and matching contributions of each family member that
are combined to determine the actual contribution ratio and the excess aggregate
contributions for the family unit are allocated among family members in
proportion to the contributions of each family member that have been combined.

                (2) If the highly compensated employee's ACR is determined by
combining the contributions and compensation of only those family members who
are highly compensated without regard to family aggregation, then the ACR is
reduced in accordance with the leveling method but not below the ACR of eligible
nonhighly compensated family members. Excess aggregate contributions are
determined by taking into account the contributions of the eligible family
members who are highly compensated without regard to family aggregation and are
allocated among such family members in proportion to their contributions.

                (3) In the case of a highly compensated employee who is either a
5% owner or one of the ten most highly compensated employees and is thereby
subject to the family aggregation rules of section 414(q)(6), the actual
contribution ratio (ACR) for the family group (which is treated as one highly
compensated employee) is the greater of (1) the ACR determined by combining the
contributions and compensation of all eligible family members who are highly
compensated without regard to family aggregation, and (2) the ACR determined by
combining the contributions and compensation of all eligible family members.
Except to the extent taken into account in the preceding sentence, the
contributions and compensation of all family 



                                       98
<PAGE>   102

members are disregarded in determining the actual contribution percentages for
the groups of highly compensated employees and nonhighly compensated employees.

                (4) In the case of a highly compensated employee whose actual
contribution ratio (ACR) is determined under the family aggregation rules, the
determination of the amount of excess contributions shall be made as follows:
the ADR is reduced by the amount required to cause the employee's actual
deferral ratio to equal the ratio of the highly compensated employee with the
next highest actual deferral ratio. If a lesser reduction would enable the
arrangement to satisfy the actual deferral percentage test, only this lesser
reduction may be made. This process must be repeated until the excess
contributions are allocated among the family members in proportion to the
contributions of each family member that have been combined.

        (b) The amount of excess contributions for a highly compensated employee
will be determined in the following manner: first, the actual contribution ratio
(ACR) of the highly compensated employee with the highest ACR is reduced to the
extent necessary to satisfy the actual contribution percentage (ACP) test or
cause such ratio to equal the ACR of the highly compensated employee with the
next highest ratio; and second, this process is repeated until the ACP test is
satisfied. The amount of excess contributions for a highly compensated employee
is then equal to the total of elective and other contributions taken into
account for the ACP test minus the product of the employee's contribution ratio
as determined above.

        (c) The amount of excess contributions to be distributed shall be
reduced by excess deferrals previously distributed for the taxable year ending
in the same plan year and excess deferrals to be distributed for a taxable year
will be reduced by excess contributions previously distributed for the plan
beginning in such taxable year.

        (d) Excess Aggregate Contributions of participants who are subject to
the family member aggregation rules shall be allocated among the family members
in proportion to the Employee and Matching Contributions (or amounts treated as
Matching Contributions) of each family member that is combined to determine the
combined ACP.

        16.09
        Failure to Correct Excess Contribution

        Failure to correct excess contributions by the close of the plan year
following the plan year for which they were made will cause the Plan to fail to
satisfy the requirements for the plan year for which the excess contributions
were made and for all subsequent years they remain in the trust. Also, the
employer will be liable for a 10% excise tax on the amount of excess
contributions unless they are corrected within 2 1/2 months after the close of
the plan year for which they are made. Excess Aggregate Contributions shall be
treated as annual additions under the Plan.

        17.01
        Profit Sharing Plan Integration

        (a) Employer contributions for the plan year plus any forfeitures will
be allocated to participants' accounts as follows:

                (1) Contributions and forfeitures will be allocated to each
participant's account in the ratio that each participant's total compensation
bears to all participants' total compensation, but not in excess of 3% of each
participant's compensation

                (2) Any contributions and forfeitures remaining after the
allocation in Step One will be allocated to each participant's account in the
ratio that each participant's compensation for the plan year in excess of the
integration level bears to the excess compensation of all participants, but not
in excess of 3%. Steps one and two shall apply only in years in which the plan
is top heavy. Steps one and two, if the Plan is top heavy, shall not require an
employer contribution, but shall be the allocation method if employer
contributions are made or forfeitures are allocated in the Plan Year.

                (3) Any contributions and forfeitures remaining after the
allocation in Step Two will be allocated to each participant's account in the
ratio that the sum of each participant's total compensation and compensation in
excess of the integration level bears to the sum of all participants total
compensation and compensation in excess of the integration level, but not in
excess of the profit-sharing maximum disparity rate.

                (4) Any remaining employer contributions or forfeitures will be
allocated to each participant's account in the ratio that each participant's
total compensation for the plan year bears to all participants' total
compensation for that year.

        17.02
        Integration Level

        (a) The integration level shall be equal to the taxable wage base or
such lesser amount elected by the employer in the adoption agreement. The
taxable wage base is the contribution and benefit base in effect under section
230 of the social Security Act at the beginning of the plan year.

        The maximum profit sharing disparity rate is equal to the lesser of:

        (1) 2.7%

        (2) the applicable percentage determined in accordance with the table
below.

                        ARTICLE XVIII-ELIGIBLE ROLLOVERS

        18.01
        Distributions

        This Article applies to distributions made on or after January 1, 1993.
Notwithstanding any provision of the plan to the contrary that would otherwise
limit a distributee's election under this Article, a distributee may elect, at
the time and in the manner prescribed by the plan administrator, to have any
portion of an eligible rollover distribution paid directly to an eligible
retirement plan specified by the distributee in a direct rollover.

        18.02
        Definitions

        (a) Eligible rollover distribution means any distribution of all or any
portion of the balance to the credit of the distributee, except that an eligible
rollover distribution does not include: any distribution that is one of a series
of substantially equal periodic payments (not less frequently than annually)
made for the life (or life expectancy) of the distributee or the joint lives (or
joint life expectancies) of the distributee and the distributee's designated
beneficiary, or for a specified period of ten year or more; any distribution to
the extent such distribution is required under section 401(a) (9) of the Code;
and the portion of any distribution that is not includible in gross income
(determined without regard to the exclusion for net unrealized appreciation with
respect to employer securities).

        (b) Eligible retirement plan means an individual retirement account
described in section 408(a) of the Code, an individual retirement annuity
described in section 408(b) of the Code, an annuity plan described in section
403(a) of the Code, or a qualified trust described in section 401(a) of the
Code, that accepts the distributee's eligible rollover distribution. However, in
the case of an eligible rollover distribution to the surviving spouse, an
eligible retirement plan is an individual retirement account or individual
retirement annuity.

        (c) A Distributee includes an employee or former employee. In addition,
the employee's or former employee's surviving spouse and the employee's or
former employee's spouse or former spouse who is the alternate payee under a
qualified domestic relations order, as defined in section 414(p) of the Code,
are distributees with regard to the interest of the spouse or former spouse.

        (d) Direct rollover means payment by the Plan to the eligible retirement
plan specified by the distributee.

to the provisions of Articles 2, 10 and 11 only, the shareholders of INTEGRAL
NETWORKING (collectively "INTEGRAL NETWORKING Shareholders").

                                    RECITALS

        A. The parties intend that, subject to the terms and conditions
hereinafter set forth, RMS Sub Inc. will merge with and into INTEGRAL NETWORKING
in a reverse triangular merger (the "Merger"), with INTEGRAL NETWORKING to be
the surviving corporation of the Merger, all pursuant to the terms and
conditions of this Agreement. a Certificate of Merger substantially in the form
of Exhibit A-1 (the "Certificate of Merger"), an Agreement of Merger
substantially in the form of Exhibit A-2 (the "Agreement of Merger") and the
applicable provisions of the laws of the states of Delaware and California. Upon
the effectiveness of the Merger, all the outstanding Common Stock of INTEGRAL
NETWORKING will be converted into Common Stock of CRL Network in the manner and
on the basis determined herein and as provided in the Certificate of Merger and
the Agreement of Merger.

        B. It is intended by the parties hereto that the Merger shall constitute
a reorganization within the meaning of Section 3 68(a)(1)(A) of the Internal
Revenue Code of 1986, as amended (the "Code"), by virtue of the provisions of
Section 368(a)(2)(E) of the Code.

        C. At the Closing of this Agreement:

               1. Robert L. Ross is entering into with CRL Network an Employment
Agreement and Noncompetition Agreement substantially in the form of Exhibit B-1
and B-2.

               2. Each of the INTEGRAL NETWORKING Shareholders is entering into
an Escrow Agreement in substantially the form of Exhibit C hereto (the "Escrow
Agreement").

        NOW, THEREFORE, the parties hereto agree as follows:

        1. PLAN OF REORGANIZATION

               1.1. The Merger. The Certificate of Merger and the Agreement of
Merger will be filed with the Secretaries of State of the States of Delaware and
California, respectively, as soon as practicable after the Closing (as defined
in Section 6.1 below). The effective time of the Merger as specified in the
Certificate of Merger and the Agreement of Merger (the "Effective Time") will
occur on or before December 21, 1998, or on such other date as the parties
hereto may mutually agree upon. Subject to the terms and conditions of this
Agreement, the Certificate of Merger and the Agreement of Merger, RMS Sub Inc.
will be merged with and into INTEGRAL NETWORKING in a statutory merger pursuant
to the Certificate of Merger and the Agreement of Merger and in accordance with
applicable provisions of Delaware and California laws as follows:

                      1.1.1. Conversion of INTEGRAL NETWORKING Shares. Each
share of INTEGRAL NETWORKING Common Stock, no par value (the "INTEGRAL
NETWORKING Common Stock"), that is issued and outstanding immediately prior to
the Effective Time will, by virtue of the Merger and at the Effective Time, and
without further action on the part of any holder thereof, be converted into the
Applicable Number (determined in


<PAGE>   8
accordance with Section 1.1.2 hereof) of fully paid and nonassessable shares of
CRL Network Common Stock, $0.001 par value ("CRL Network Common Stock").

                      1.1.2. Definitions. Unless there is an adjustment to the
shares to be issued in the Merger pursuant to Section 1.1.3 below, The
Applicable Number for the conversion of the Integral Common Stock will be
determined by dividing 1,304,498 by the sum of the total number of issued and
outstanding shares of INTEGRAL NETWORKING Common Stock at the Effective Time.

                      1.1.3. Adjustments for Capital Changes. If prior to the
Merger, CRL Network recapitalizes either through a split-up of its outstanding
shares into a greater number, or through a combination of its outstanding shares
into a lesser number, or reorganizes, reclassifies or otherwise changes its
outstanding shares into the same or a different number of shares of other
classes (other than through a split-up or combination of shares provided for in
the previous clause), or declares a dividend on its outstanding shares payable
in shares or securities convertible into shares, the calculation of the
Applicable Number governing the conversion of INTEGRAL NETWORKING Common Stock
will be adjusted appropriately.

                      1.1.4. Conversion of RMS Sub Inc. Shares. Each share of
RMS Sub Inc. Common Stock, $0.01 par value ("RMS Sub Inc. Common Stock"), that
is issued and outstanding immediately prior to the Effective Time will, by
virtue of the Merger and without further action on the part of the sole
stockholder of RMS Sub Inc., be converted into and become one (1) share of
INTEGRAL NETWORKING Common Stock that is issued and outstanding immediately
after the Effective Time, and the shares of INTEGRAL NETWORKING Common Stock
into which the shares of RMS Sub Inc. Common Stock are so converted shall be the
only shares of INTEGRAL NETWORKING Stock that are issued and outstanding
immediately after the Effective Time.

               1.2. Fractional Shares. No fractional shares of CRL Network
Common Stock will be issued in connection with the Merger, but in lieu thereof,
the holder of any shares of INTEGRAL NETWORKING Common Stock who would otherwise
be entitled to receive a fraction of a share of CRL Network Common Stock will
receive from CRL Network, promptly after the Effective Time, an amount of cash
equal to $1.15, multiplied by the fraction of a share of CRL Network Common
Stock to which such holder would otherwise be entitled.

               1.3. Escrow Agreement. Pursuant to the Escrow Agreement, on the
Closing Date, CRL Network will (i) withhold, pro rata, from the shares of CRL
Network Common Stock that would otherwise be delivered to the INTEGRAL
NETWORKING Shareholders, 10% of the total number of shares of CRL Network Common
Stock issued to them in the Merger and (ii) deposit or cause to be deposited in
escrow certificates representing the shares thus withheld. The shares of CRL
Network Common Stock withheld pursuant to this Section 1.3 at the Closing (the
"Escrow Shares") will be held as collateral for the indemnification obligations
of the INTEGRAL NETWORKING Shareholders under Section 10.2 below and pursuant to
the Escrow Agreement, pending their release from escrow pursuant to the Escrow
Agreement.

               1.4. Effects of the Merger. At the Effective Time: (a) the
separate existence of RMS Sub Inc. will cease and RMS Sub Inc. will be merged
with and into INTEGRAL NETWORKING and INTEGRAL NETWORKING will be the surviving
corporation pursuant to the terms of the Certificate of Merger and the Agreement
of Merger; (b) the Articles of Incorporation and Bylaws of INTEGRAL NETWORKING
will be amended to read as set forth in Exhibit 1.4A and B as the Articles of
Incorporation and Bylaws of the surviving corporation; (c) each share of
INTEGRAL NETWORKING Common Stock outstanding immediately prior to the Effective
Time will be converted as provided in this Section 1; (d) each share of RMS Sub
Inc. Common Stock outstanding immediately prior to the Effective Time will be
converted into one (1) outstanding share-of INTEGRAL NETWORKING Common Stock and
each share of INTEGRAL NETWORKING Common Stock will be converted as provided in
Sections 1.1 and 1.2; (e) the sole Director and executive officer of CRL Network
remaining unchanged and the sole director of RMS Sub Inc. immediately prior to
the Effective Time will become the sole director of the surviving corporation
and the officers of RMS Sub Inc. will become the officers of the surviving
corporation; and (f) the Merger will, at and after the Effective Time, have all
of the effects provided by applicable law.

NETWORKING peaceful and undisturbed possession of the subject matter of the
lease. INTEGRAL NETWORKING is not in violation of any material zoning, building,
safety or environmental ordinance, regulation or requirement or other law or

                      2.23.4. Investment Intent. Each of the INTEGRAL NETWORKING
Shareholders is receiving the Restricted Securities in the Merger for investment
for such INTEGRAL NETWORKING Shareholder's own account only and not with a view

Act and constitutes "restricted securities" under Rule 144(d) of the Securities
Act, and has been issued in reliance on the exemptions for non-public offerings
provided by Rule 506 and Section 4(2) of the Securities Act, which exemptions
depend upon, among other things, the representations made and information

not satisfied, registration under the Securities Act or some other exemption
from the registration requirements of the Securities Act will be required in
order to dispose of the Restricted Securities, and that such stockholder may be
required to hold his or her shares for a significant period of time prior to
reselling them.

                      2.23.7. Legends. Each of the INTEGRAL NETWORKING
Shareholders also understands and agrees that there will be placed on the
certificates evidencing the ownership of the Restricted Securities, the
following legends, in addition to any legends required by applicable state
laws):

ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE
DISTRIBUTION THEREOF THE SECURITIES MAY NOT BE OFFERED, SOLD, PLEDGED, OR
TRANSFERRED UNLESS THERE IS AN OPINION OF COUNSEL SATISFACTORY TO THE ISSUER
THAT (1) A REGISTRATION STATEMENT UNDER THE ACT (AND CURRENT PROSPECTUS) IS IN
EFFECT AS TO THE SECURITIES, (2) AN EXEMPTION THEREFROM IS AVAILABLE, OR (3) THE
SECURITIES ARE SOLD PURSUANT TO RULE 144 OF THE ACT.

have been so transferred in violation of any provision of this Agreement. CRL
Network agrees that such stop transfer instructions and legends will be promptly
removed if the provisions of the Securities Act are complied with.

                      2.23.9. No Intention to Transfer. Each of the INTEGRAL
NETWORKING Shareholders has no current plan or intention to engage in a sale,
exchange, transfer, distribution, redemption or reduction in any way of the
INTEGRAL NETWORKING Shareholder's risk of ownership by short sale or otherwise,
or other disposition, directly or indirectly, of more than fifty percent of any

each of the INTEGRAL NETWORKING Shareholders provides to CRL Network hereunder
concerning such INTEGRAL NETWORKING Shareholder's financial position and
knowledge of financial and business matters is correct and complete as of the
date set forth above.

                      2.23.11. Ability to Bear Economic Risk. Whether or not

bear the economic risk of the INTEGRAL NETWORKING Shareholder's investment, (ii)
is able to hold the Restricted Securities for an indefinite period of time,

investment in the Restricted Securities and (iv) has adequate means of providing

NETWORKING Shareholders represents that at no time was such INTEGRAL NETWORKING

INTEGRAL NETWORKING Shareholders, elect to take all necessary steps properly to
contest any Claim involving third parties or to prosecute such Claim to
conclusion or settlement satisfactory to the Representative. If the

consent of either CRL Network (if the Representative defends the Claim) or the
Representative (if CRL Network defends the Claim), such consent not to be
unreasonably withheld.

such further acts and things, and execute all such documents as the

transactions contemplated by this Agreement, including without limitation, the

pertaining to the indemnification referred to in this Agreement, including the
power to compromise any claim on behalf of the INTEGRAL NETWORKING Shareholders
and to transact matters of litigation; (ii) to consummate any transactions
contemplated by the Escrow Agreement; (iii) to do or refrain from doing any
further act or deed on behalf of the INTEGRAL NETWORKING Shareholders which the

notices and service of process on behalf of the INTEGRAL NETWORKING Shareholders
in connection with any claims or matters under this Agreement;

                           (b) The Representative or any successor
Representative shall have the power to substitute any other INTEGRAL NETWORKING
Shareholder as a successor Representative hereunder. In the event that the

appointed, a substitute Representative shall be appointed by INTEGRAL NETWORKING
Shareholders holding a majority of the voting power of the shares of INTEGRAL
NETWORKING as of the date of this Agreement.

                           (c) The Representative shall act for the INTEGRAL
NETWORKING Shareholders on all matters set forth in this Agreement in a manner
the Representative believes to be in the best interests of the INTEGRAL
NETWORKING Shareholders and consistent with his obligations under this
Agreement, but the Representative shall not be responsible to the INTEGRAL
NETWORKING Shareholders for any loss or damages the INTEGRAL NETWORKING
Shareholders may suffer by reason of the performance by the Representative of
his duties under the Agreement, other than loss or damage arising from willful
violation of the law or gross negligence in the performance of his duties under
this Agreement. The INTEGRAL NETWORKING Shareholders agree, jointly and
severally, to indemnify' and hold harmless the Representative for any loss or
damage arising from the performance of his duties as Representative hereunder,

payment of such indemnity in full, be surrogated to all rights of such

        under the U.S. Simply Business Premium Line, including the Variable Rate
        Amount and all Fixed Rate Loans, shall not exceed an aggregate amount
        equal to $50,000.00 (as such amount may be changed from time to time,
        the "Credit Limit").

2.      PROMISE TO PAY. Borrower promises to pay to the order of Lender, in
        accordance with the terms of this Agreement and the Terms and
        Conditions, a principal amount equal to the Credit Limit or so much
        thereof as may be outstanding, together with interest as set forth in
        this Agreement. If Borrower is granted an increase in the Credit Limit
        at any time, Borrower also promises to pay that amount to the order of
        Lender.

3.      VARIABLE RATE LOANS.

        a.      VARIABLE INTEREST RATE. Interest shall accrue on the Variable
                Rate Amount at a variable per annum interest rate (the "Variable

                payments on the Variable Rate Amount are being paid by automatic
                debit from Borrower's business account with Lender or another
                U.S. Bank affiliated with Lender; or (ii) the Prime Rate plus
                3.0000% if payments On the Variable Rate Amount are not being
                paid by automatic debit from Borrower's business account with
                Lender or another U.S. Bank affiliated with Lender.

        b.      PAYMENT SCHEDULE.

               (i)    Subject to Section 3(b)(iii), interest on the Variable
                      Rate Amount shall be paid on the 5th day of October and on
                      the same day of each month thereafter and on any day when

        (iii)   If the U.S. Simply Business Premium Line is cancelled, unless an
                Event of Default has occurred, the principal balance of the
                Variable Rate Amount outstanding on the date of cancellation
                shall be automatically converted to a Fixed Rate Loan bearing
                interest at the Fixed Interest Rate in effect on such date. On
                the day of each month specified in Section 3(b)(i), beginning on
                the first such date to occur following the cancellation date and
                on the same day of each month thereafter, Borrower shall repay
                such Fixed Rate Loan in 59 approximately equal installments of
                principal and interest, each in an amount sufficient to amortize

                Loan at a rate equal to the applicable Fixed Interest Rate. The
                Fixed Interest Rate for any Fixed Rate Loan is a per annum
                interest rate equal to the Prime Rate, as in effect on the date
                such Fixed Rate Loan is made, plus (i) 3.0000% if payments on
                the Fixed Rate Loans are being paid by automatic debit from
                Borrower's business account with Lender or another U.S. Bank
                affiliated with Lender and (ii) 3.5000% if payments on the Fixed
                Rate Loan are not being paid by automatic debit from Borrower's
                business account with Lender or another U.S. Bank affiliated
                with Lender. Although different Fixed Rate Loans may bear
                different interest rates, unless the Default Rate is applicable,
                the interest rate for any individual Fixed Rate Loan will not
                change during the term of such Fixed Rate Loan.

        b.      PAYMENT SCHEDULE. Each month, on the payment due date
                established by Borrower, beginning with the month following the
                month in which any Fixed Rate Loan is made, Borrower shall repay
                each Fixed Rate Loan in approximately equal installments of
                principal and interest, each in an amount sufficient to fully
                amortize the balance of principal and interest of the Fixed Rate
                Loan over the amortization period selected by Borrower;
                provided, however, that the then outstanding balance of
                principal and interest of each Fixed Rate Loan shall be due and
                payable in full at the end of the amortization period for such
                Fixed Rate Loan.

        c.      ADDITIONAL INTEREST PAYMENTS. In addition to the payments set
                forth in Section 4b, upon the date of conversion of any Fixed

                Lender all interest accrued to the date of conversion.

        to time, including without limitation the following:

               equal to $375.00. The set-up fee is payable on the date this
               Agreement is signed. Unless otherwise requested by Borrower, the
               set-up fee will be deemed to be a Variable Rate Loan made on such
               date.

        b.     ANNUAL FEE. In advance, a non-refundable annual Loan Fee in an
               amount equal to $150.00, payable on each anniversary of the date

        its option, increase the interest rate applicable to the Variable Rate
        Amount and each Fixed Rate Loan, by 5% per annum ("Default Rate").
        However, the interest rate will not exceed the maximum rate permitted by
        applicable law.

7.      LATE CHARGE. If any payment is 15 days or mere past due, Borrower will
        be charged a late charge of 5% of the delinquent payment.

        Borrower's and each Guarantor's creditworthiness and the basis for
        Lender's credit accommodations to Borrower. In connection with any such
        review, Borrower will furnish and will cause any Guarantor to furnish
        Lender with any information regarding Borrower's or any Guarantor's

        Without prejudice to Lender's rights at any time to decline to make any
        requested Loan, to cancel the U.S. Simply Business Premium Line, and to
        reduce the Credit Limit, if Lender determines that there has been a
        material adverse change in the financial condition of Borrower or any

        its option, exercise any of the default remedies available to Lender.

                           AIRPLANE LEASING AGREEMENT

        This Airplane Leasing Agreement (the "Agreement") is entered into on
February 15th, 1999, by and between CRL Network Services, Inc., a California
corporation ("Customer"), and FBN Holding Corp., a Delaware corporation (the
"Company").

                                    RECITALS

        Whereas, the Company has, from time to time, leased a Cessna Citation I
aircraft, serial # 500-107, U.S. Registration N79RS (the "Airplane") owned by
the Company to Customer for various transportation needs of Customer, and in
return therefor, Customer has paid the Company's hourly lease rate as in effect
from time-to-time;

        Whereas, the Company and Customer desire to set forth the terms and
conditions of such arrangement in this Agreement;

        Now, therefore, in consideration of the foregoing recitals, the terms
and conditions set forth herein, and other good and valuable consideration, the
receipt and adequacy of which are hereby acknowledged, the parties agree as
follows:

        1. LEASE OF AIRPLANE. For so long as the Company shall own and operate
the Airplane, and during such periods of time as the Airplane may be available
for use as determined by the Company, the Company agrees to the non-exclusive
lease of the Airplane to Customer on the terms and conditions set forth in this
Agreement. If Customer desires to lease the Airplane, Customer shall contact the
Company and inquire about its availability. If the Airplane is available during
the period requested, the Company shall make the Airplane available to Customer.
For such use, Customer shall pay to the Company the hourly rate that shall then
be in effect for each hour that the Airplane in flight; provided, however, that
such hourly rate shall be the lowest hourly rate offered by the Company to any
third party (other than Customer) during the preceding three months. Subject to
the proviso of the immediately preceding sentence, the Company may change the
hourly rate upon thirty (30) days prior written notice to the Company. Any
amounts due by Customer shall be paid within thirty (30) days following the
completion of each use of the Airplane by Customer. The Company's lease of the
Airplane shall be on an all inclusive "wet" basis, meaning that the hourly rate
constitutes the entire payment to be made by Customer for its use of the
Airplane and all gasoline used by Customer shall be supplied by the Company.

        2. TERMINATION. This Agreement may be terminated at any time by either
party upon fifteen (15) days prior written notice to the other party.

        3. NO OBLIGATION ON CUSTOMER TO LEASE AIRPLANE. Nothing set forth herein
shall create any obligation on the part of the Company to lease the Airplane.
Without limiting the generality of the foregoing, the Company shall be free at
any time to lease any other airplanes or arrange any other form of
transportation it may elect in any and all circumstances. If

<PAGE>   2
Customer shall elect to lease the Airplane, Customer shall have no obligation to
lease the Airplane for any minimum period of time.

        4. REPRESENTATIONS. Each party represents and warrants that this
Agreement has been duly and validly executed and delivered by such party, and
that this Agreement constitutes the valid and binding obligation of such party,
enforceable in accordance with its terms.

        5. INSURANCE. The Company shall maintain at all times both hull and
liability insurance coverage with respect to the Airplane in amounts customary
for similar craft.

        6. INDEMNIFICATION. Customer shall indemnify the Company against any
loss of or damage to the Airplane and any liability arising out of or in
connection with Customer's negligence or misconduct in connection with the
operation or use of the Airplane, reasonable wear and tear accepted.

        7. USE. Customer shall use the Airplane in conformance with all
requirements of state and federal statutes and regulations, and in conformance
with the limitations set forth in the insurance coverage described in Section 5
of this Agreement. Customer agrees to land the Airplane only at established
airports except as a precautionary or emergency measure, and to allow only
licensed and qualified pilots to fly the Airplane. Customer shall not pledge,
loan, mortgage, sublet or part with the possession of the Airplane or permit any
liens to be incurred upon the Airplane during the periods of time Customer that
leases the Airplane pursuant to this Agreement.

        8. MAINTENANCE. During the periods of time that Customer leases the
Airplane pursuant to this Agreement, Customer shall keep the Airplane in good
condition. At the end of each lease period, Customer shall return the Airplane
to the Company in as good a condition as when received, reasonable wear and tear
excepted.

        9. DEFAULT. Upon material default of any of the conditions of this
Agreement, the Company shall have the right to terminate this Agreement and to
take possession of the Airplane without legal process wherever the Airplane may
be found.

        10. DISPUTE RESOLUTION AND BINDING ARBITRATION. Customer and the Company
agree that in the event a dispute arises concerning or relating to this
Agreement, such dispute shall be submitted to binding arbitration in accordance
with the rules of the American Arbitration Association then in effect. The
arbitration shall take place in Reno, Nevada, and both Customer and the Company
agree to submit to the jurisdiction of the arbitrator selected in accordance
with American Arbitration Association rules and procedures. Customer and the

this Agreement, and that the award of the arbitrator shall be final and binding
on both parties, and nonappealable. The arbitrator shall have discretion to
award monetary and other damages, or no damages, and to fashion such other
relief as the arbitrator deems appropriate. The arbitrator shall also have
