                                    PART I
 
ITEM 1. BUSINESS.
 
GENERAL
 
  NetVantage, Inc. ("NetVantage" or the "Company") is a leading provider of
Ethernet Workgroup switching products designed to increase the information
handling capacity of new and installed Local Area Networks or "LANs." Other
applications of use for the Company's switching products include connecting
LANs to each other to extend the network's scope and power and to provide
installed networks with the ability to connect to networking devices
incorporating new technologies such as Asynchronous Transfer Mode or "ATM,"
and Gigabit Ethernet. The Company's switching products require no special
skills to install, and require no changes to existing user network equipment,
wiring, hub equipment, software protocols or applications.
 
  The Company markets its products worldwide exclusively through Original
Equipment Manufacturers ("OEMs"). Sales to the three largest customers
amounted to $8,003,350 (31%), $5,712,598 (22%), and $3,773,259 (14%) in 1996
and sales to the three largest customers amounted to $256,173 (20%), $254,705
(20%) and $206,454 (16%) in 1995. The three largest customers in 1996 were
different than the three largest customers in 1995.
 
  The Company has devoted substantial resources to research and development,
with the belief that its future success is highly dependent on its ability to
enhance existing products, as well as to develop new products which meet both
the needs of its customers and maintain technological competitiveness in the
OEM market.
 
  Also of significance to the Company is the on-going development and
expansion of its account base. Key to this development and expansion is high
visibility within the existing account base as well as significant continuing
field activity to expand the number of OEMs. As a result, the Company intends
to increase the size of its sales force to meet these objectives.
 
  As cost is a fundamental decision criteria in the OEM Ethernet switching
market, manufacturing efficiencies and quality are also considered important
success factors. Shipping volumes continue to increase resulting in
substantial economies of scale from both a raw material and actual cost of
manufacturing perspective. Current contract manufacturing capacities are
expected to be adequate to meet anticipated volumes. To monitor quality
output, the Company retains salaried employees on-site at the contract
manufacturer's facility. Given the anticipated increase in product shipments,
the Company intends to increase its quality and test resources in order to
maintain continued high quality.
 
  Any contemplated or planned increase in resources or investment is highly
dependent on several factors, including the growth of the Company's revenue,
new product delivery schedules, product acceptance in the marketplace, and
retention of existing employees coupled with the Company's ability to attract
appropriate, experienced personnel. Due to the anticipated increase in fixed
operating expenses, any of the above factors could adversely affect the
Company's revenues and thereby negatively impact the Company's operating
results.
 
  To provide the necessary working capital to support the anticipated
significant growth of the Company, on October 24, 1996, the Company completed
the redemption of its Class A Warrants which resulted in the exercise of 99.9%
of the Class A Warrants and the issuance of 2,335,568 shares of Class A Common
Stock and the same number of Class B Warrants. In addition, as of October 24,
1996, 368,360 Class B Warrants were voluntarily exercised, resulting in the
issuance of 386,778 shares of Class A Common Stock. Total proceeds from the
exercise of all Class A Warrants on October 24, 1996 was approximately
$17,368,000.
 
  The Company redeemed its remaining Class B Warrants on January 10, 1997.
Prior to the redemption date, more than 3.5 million (or greater than 99%) of
the outstanding Class B Warrants were exercised, resulting in gross proceeds
to the Company of approximately $27,000,000.

  The Company was originally incorporated in California on March 12, 1991. In
late 1994, the Company changed its state of incorporation from California to
Delaware. The statements contained in this report regarding matters that are
not statements of historical fact are forward-looking statements within the
meaning of Section 21E of the Securities Exchange Act of 1934, as amended.
Actual results may differ materially from the statements made in this report
as a result of various factors, including those stated in "Risk Factors" and
elsewhere in this report and other factors which are listed from time to time
in other documents filed by the Company with the Securities and Exchange
Commission.
 
PRODUCTS
 
  In mid-1994, the Company introduced an 8 port 10MB Ethernet switch and began
commercial shipments of this product in late 1994. In the same year, the
Company began development of a Token Ring Switch. In early 1996, the Company
decided to halt further development of the Token Ring Switch and focus the
Company's resources on the larger, faster growing Ethernet switching market.
 
  In December 1995, the Company introduced a 16 port 10MB Ethernet switch with
1 high speed 100MB uplink, to potential OEM customers. Significant shipments
of the product began in March of 1996. Throughout 1996, the Company released a
number of new products derived from the original 16 port plus 1 uplink
product. These products include an 8 port 10MB Ethernet switch with 1 high
speed 100MB uplink, and the introduction of fiber interfaces on the high speed
uplinks. This product set accounted for substantially all of the Company's
1996 revenues.
 
PRODUCT DEVELOPMENT
 
  During the years ended December 31, 1996, 1995 and 1994, the Company
incurred research and development expenses of $4,312,927, $2,192,536 and
$847,872, respectively. The Company expects to expend substantial funds in the
future for research and development.
 
  On April 30, 1996, the Company acquired all of the outstanding capital stock
of MultiMedia LANs, Inc. ("MultiMedia"), and merged MultiMedia into the
Company. As a result, the Company acquired significant Application Specific
Integrated Circuit or "ASIC" expertise. The fundamental advantage of ASIC
development to the Company is higher levels of component integration resulting
in reduced costs to manufacture product.
 
  In the spring of 1996, the Company began work on its first ASIC, code named
"Coyote." The Coyote ASIC is a 100Mbps Media Access and Direct Memory
controller with customized features for Ethernet switching. The purpose of
Coyote is to consolidate several high speed uplink components into a single
chip resulting in a significant reduction in the cost of goods sold. The
Company completed testing of Coyote on December 30, 1996.
 
  The Coyote ASIC is expected to be integrated into the high speed uplinks of
the core 8 and 16 port 10MB switches shipping to OEMs in early 1997. The
product line is also expected to be expanded by adding a second high speed
uplink to both the 8 and 16 port models.
 
  In the fall of 1996, the Company expanded its ASIC development expertise,
staffing two remote design centers. Concurrent with this expansion, the
Company started the development of two new ASIC-based families of Ethernet
switches, internally named "Cougar" and "Cyclone." Both products feature high
levels of system integration. Specifically, the entire switching fabric of
both products will be integrated into a single chip.
 
  Technology for both Cougar and Cyclone was derived from a parallel
development, code named "Corvette." Corvette is a 100MB high performance
Ethernet switch developed in Field Programmable Gate Array or FPGA technology.
As a result of problems with the FPGAs, the release of Corvette has been
delayed indefinitely.
 
  Cougar is a 24 port 10MB Ethernet switch with up to 4 high speed 100MB
uplinks. The product can be either managed or unmanaged and has a number of
configuration options to meet OEM customer requirements. Cougar has low per
port costs and is targeted at the low-cost, high performance desktop and
Workgroup Ethernet switching market. The Company also intends to target the
Cougar product family in the shared media hub replacement market, a market
which the Company believes will grow substantially over the next three years.
 
                                       3
<PAGE>
 
  Cyclone is a multiple configuration product platform that features high
speed, high performance 10/100 Mbps Ethernet switching with Gigabit and/or ATM
uplink support. Other configurations include full Gigabit switching. Cyclone
supports industry standards for virtual LANs ("VLAN"), multimedia traffic
prioritization ("QoS") and network management ("RMON"). The Company
anticipates that both the Cougar and the Cyclone switches will be initially
released in the fourth quarter of 1997. Together, the Cougar and Cyclone are
expected to form a comprehensive suite of products for Ethernet Workgroup and
desktop switching. However, no assurance can be given that the Company's
products will be developed on schedule and will be accepted by the market.
 
SALES AND MARKETING
 
  Between the period from April 1995 to November 1995, the Company attempted
to develop a value-added reseller and reseller distribution channel. In
November 1995, the Company changed its strategic marketing emphasis electing
to distribute its products to OEMs, and discontinued its efforts to market
through other distribution channels.
 
  The Company currently markets its products exclusively on an OEM basis to
domestic and foreign customers, through a sales staff primarily located at the
Company's El Segundo office. The Company signed its first OEM contract
agreement with Hewlett Packard in February of 1996. Since then, the Company
has grown its OEM account base from two in the first quarter of 1996 to
nineteen in the fourth quarter of 1996. The Company continues to expand its
account base.
 
COMPETITION
 
  The Company faces competition on three fronts: from companies that market
their own switches on an OEM basis, including Accton, D-Link, Network
Peripherals and Xylan; from companies that develop commercial switching
silicon which facilitates the development of LAN switches, including AMD,
Galileo and Texas Instruments; and from internal switch development by the
Company's existing OEM customers. Many of the Company's current and potential
competitors have significantly greater financial, technical, marketing and
other resources and larger installed customer bases.
 
  To improve its competitive position in the market, continuous development
and introduction of new products and product features must be achieved in a
timely and cost effective manner, so as to keep pace with competitors'
offerings, technological developments and changing industry standards.
 
  There can be no assurance that the Company will be able to identify,
develop, manufacture, market or support its products successfully or that the
Company will be able to respond effectively to technological changes, revised
industry standards or product announcements by competitors. Delays in new
product introductions or product enhancements, or the introduction of
unsuccessful products, could adversely affect the Company.
 
MANUFACTURING AND MATERIALS
 
  The Company designs all of the hardware sub-assemblies used in its products
and employs the services of an ISO-9002 certified manufacturer to build and
test these sub-assemblies. Final assembly, configuration and testing of the
Company's products is performed by the same contract manufacturer which
utilizes burn-in, automated testing and comprehensive inspection to assure the
quality of the finished products. The Company also conducts Ongoing
Reliability Testing to ensure that all products meet the reliability
requirements of its customers.
 
  The Company's manufacturing operations consist of the procurement of
components and the assembly, testing and quality assurance of finished goods
for shipment to its customers. The Company utilizes a one source distributor
to procure, stock and kit for assembly the bulk of its raw materials.
 
                                       4
<PAGE>
 
  Although the Company generally uses standard parts and components for its
products, certain components are currently available only from single or
limited sources. The Company believes that it will be able to obtain adequate
supplies in a timely manner from these existing sources or that any shortages
experienced will be no worse than other competitors will face. No assurance
can be given that these shortages will not occur or that the Company will not
experience an increase in price or interruption in availability of one or more
of its components that would adversely affect the Company's operating results
and business.
 
  There can be no assurance that the Company will effectively manage its
contract manufacturer or that such manufacturer will meet the Company's future
requirements for timely delivery of products of sufficient quality and
quantity.
 
PROPRIETARY RIGHTS
 
  The Company does not have any patents; however, the Company has filed a
patent application relating to the Company's core switching technology. This
patent has been approved and is awaiting issuance. The Company relies on a
combination of patent, trade secret, copyright and trademark law,
nondisclosure agreements and technical measures to establish and protect its
proprietary right in its products.
 
RISK FACTORS
 
  The following risk factors should be considered carefully in addition to the
other information contained in this report in evaluating the Company and its
prospects:
 
 Recurring Losses; Fluctuations in Quarterly Operating Results
 
  The Company's net loss for the year ended 1996 was approximately $9.9
million, with net losses since its inception totaling approximately $21.4
million. The future success of the Company is dependent upon, among other
things, the Company's ability to successfully develop and market its products,
obtain necessary capital, control costs and achieve a sustainable operating
profit. There can be no assurance that the Company will ever become
profitable.
 
  During the second half of 1996, the Company experienced a rapid growth in
revenues, principally due to the introduction and customer acceptance of a new
family of products and its decision to focus solely on the OEM market for
distribution of its products. A significant portion of the Company's revenues
have been, and will continue to be, derived from substantial orders placed by
a few OEM customers. Sales to the three major customers amounted to $8,003,350
(31%), $5,712,598 (22%), and $3,773,259 (14%) in 1996 and sales to the three
major customers amounted to $256,173 (20%), $254,705 (20%) and $206,454 (16%)
in 1995. Due to, among other things, the Company's limited customer base, the
rapidly changing nature of the markets for its products and the likelihood of
increased competition, there can be no assurance that the Company's rate of
growth in revenues will continue or increase in the future.
 
  Additionally, the Company's operating results, especially when viewed on a
quarter-to-quarter basis, are affected by a wide variety of factors,
including, among other things, the Company's success in the timely
development, introduction and shipping of its current and new products; the
mix of products sold; the Company's ability to reduce operating expenses and
to retain and recruit personnel; competition and changes in the demand for the
Company's and competitors' products; price reductions for the Company's and
competitors' products; changes in the levels of inventory held by the
Company's OEM customers; the level of usage of similar internally developed
products by the Company's OEM customers; the timing of orders from and
shipments to its OEM customers; and general economic conditions. The Company
typically operates with a relatively small backlog. As a result, quarterly
revenues and operating results generally depend on the volume and timing of,
and ability to fulfill orders received within the quarter, which are difficult
to forecast. A significant portion of the Company's expense levels are
relatively fixed in advance, based largely on the Company's forecasts of
future sales. If sales are below expectations in any given quarter, the
adverse impact of the shortfall on the Company's operating
 
                                       5
<PAGE>
 
results may be magnified by the Company's inability to adjust spending to
compensate for the shortfall. In addition, the Company currently intends to
increase its funding of product development, increase its sales and market
development activities and add sales and marketing personnel. Accordingly,
there can be no assurance that the Company will ever be able to achieve
profitability in the future, whether annually or on a quarter-to-quarter
basis.
 
  Based on the foregoing, the Company believes that its revenues and operating
results are likely to vary significantly in the future and that period-to-
period comparisons of its revenues and results of operations are not
necessarily meaningful and should not be relied upon as indications of future
performance. Further, it is likely that in the future the Company's revenues
or operating results will from time to time be below the expectations of
public market analysts and investors. In such event, the price of the
Company's Common Stock is likely to be materially adversely affected. See
"Risk Factors--Fluctuations in Market Price of the Company's Securities."
 
 Product Development and Timely Introduction of New and Enhanced Products
 
  From its inception until mid-1996, the Company was primarily engaged in
research and development and, as a result, has had limited marketing
experience to date. The market for the Company's current products is
characterized by rapidly changing technologies, evolving industry standards,
frequent new product introductions and short product life cycles. Accordingly,
the Company believes that its future success will depend on its ability to
enhance its existing products and to develop and introduce in a timely fashion
new products that achieve market acceptance. There can be no assurance that
the Company will be able to identify, develop, manufacture or market such
products successfully or that the Company will be able to respond effectively
to technological changes, industry standards revisions or product
announcements by competitors. Delays in new product introductions or product
enhancements, or the introduction of unsuccessful products, could have a
material adverse effect on the Company and its results of operations. The
Company's revenues are dependent on, among other things, the acceptance of its
products by its OEM customers, and no assurance concerning their acceptance
can be given. From time to time, the Company may announce new products,
capabilities or technologies that have the potential to replace the Company's
existing product offerings. There can be no assurance that announcements of
new product offerings will not cause its customers to defer purchasing
existing Company products, materially and adversely affecting the Company and
its results of operations.
 
  The Company has experienced delays in the development of its new products
and certain enhancements of existing products. There can be no assurance that
the Company will be successful in developing and marketing, on a timely basis
or at all, competitive products, product enhancements and new products that
respond to technological change, changes in customer requirements and emerging
industry standards, or that the Company's products will now or in the future
adequately address the changing needs of the marketplace. The inability of the
Company, due to resource constraints or technological or other reasons, to
develop and introduce, new products or product enhancements in a timely manner
could have a material adverse affect on the Company and its results of
operations.
 
 Competition
 
  Competition in the market in which the Company competes is characterized by
rapidly changing technologies, evolving industry standards, in-house or
proprietary solutions, frequent new product introductions, and rapid changes
in customer requirements. To maintain and improve its competitive position,
the Company must develop and introduce, in a timely and cost-effective manner,
new products and product features that keep pace with competitors' offerings,
technological developments and changing industry standards. The principal
competitive factors in the Company's market are price performance, feature
performance, customer support, and quality. There can be no assurance that the
Company will be able to identify, develop, manufacture or market products
successfully or that the Company will be able to respond effectively to
technological changes or product announcements by its competitors. Delays in
new product introductions or product enhancements or the introduction of
unsuccessful products could materially and adversely effect the Company and
its results of operations.
 
                                       6
<PAGE>
 
  Many of the Company's current and potential competitors have longer
operating histories and have greater financial, technical, sales, marketing
and other resources than the Company. Moreover, the Company's current and
potential competitors may respond more quickly than the Company to new or
emerging technologies or changes in customer requirements. In addition, as the
market develops, a number of companies with significantly greater resources
than the Company could attempt to increase their presence in the market by
acquiring or forming strategic alliances with competitors of the Company,
resulting in increased competition to the Company. There can be no assurance
that the Company will be able to compete successfully with such competitors.
 
 Risks Associated with Software
 
  The development, enhancement and implementation of the Company's products
entail risks of product defects or failures. The Company has in the past
discovered software bugs in certain of its products. Although to date, the
Company has not experienced material adverse effects resulting from any such
bugs, there can be no assurance that errors will not be found in existing or
new products, which may result in delay or loss of revenue, loss of market
share, failure to achieve market acceptance, or may otherwise adversely impact
the Company's business, operating results and financial condition.
 
 Dependence on Single-Source Suppliers and Contract Manufacturers
 
  Although the Company generally uses standard parts for its hardware
products, certain components, circuit boards, connectors, mechanical
assemblies and power supplies are presently available only from a single
source or from limited sources. The Company generally purchases single or
limited source components pursuant to purchase orders and has no guaranteed
supply arrangements with these suppliers. In addition, the availability of
many of these components to the Company is dependent in part on the Company's
ability to provide its suppliers with accurate forecasts of its future
requirements. The Company has generally been able to obtain adequate supplies
of parts and components in a timely manner from existing sources and endeavors
to maintain inventory levels adequate to guard against interruptions in
supplies. The Company believes that there are alternative suppliers or
alternative components for all of the components contained in its products.
However, any extended interruption in the supply of any of the key components
currently obtained from a single or limited source or the time necessary to
transition a replacement supplier's product or a replacement component into
the Company's products could disrupt its operations and have a material
adverse affect on the Company and its operating results. The Company purchases
certain components from suppliers outside the United States; however, all such
purchases are denominated in U.S. dollars and the Company believes all such
components or alternate components are available from suppliers within the
United States. The Company may also be subject to increases in component
costs, which could also have a material adverse effect on the Company and its
operating results.
 
  The Company shifted to an outsourcing strategy for the manufacture of its
products during l996. The Company relies on a single independent contractor to
manufacture all of its products to its specifications. Any difficulties
experienced by the Company's manufacturer, on which the Company is solely
dependent for the supply of its products, could materially adversely affect
the Company and its operating results.
 
 Limited Number of Customers
 
  The Company currently markets its products to a limited number of OEM
customers, which purchase the Company's products under purchase orders. In
addition to the Company's products, such customers may also use products that
are developed internally or purchased from third parties, that compete with
the Company's products. The Company seeks to retain and attract customers by
providing a high quality, feature rich product at a price that makes the
Company's products the most cost effective and attractive alternative.
However, there can be no assurance that the Company will be successful in
retaining or attracting customers. The loss of a significant customer or a
limited number of smaller customers could have a material adverse affect on
the Company and its results of operations.
 
 Management of Growth
 
  The Company is currently experiencing rapid growth and expansion, which has
placed, and will continue to place, a significant strain on its
administrative, engineering and operational resources and increased demands on
 
                                       7
<PAGE>
 
its systems and controls. This growth has resulted in a continuing increase in
the level of responsibility for both existing and new management personnel.
The Company anticipates that its continued growth will require it to recruit
and hire a substantial number of new engineering, sales and marketing and
managerial personnel. There can be no assurance that the Company will be
successful at hiring or retaining these personnel. The Company's ability to
manage its growth successfully will also require the Company to continue to
expand and improve its operational, management and financial systems and
controls. If the Company's management is unable to manage growth effectively,
the Company's business, results of operations and financial condition may be
materially and adversely affected.
 
 Recent Management Changes; Dependence on Key Personnel
 
  Over the last two years, the Company has experienced significant changes in
its Board of Directors, management and certain other key employees.
Resignations included, among others, M. Charles Fogg, from the positions of
President, Chief Executive Officer and Director, in March of 1996; Roel
Pieper, from his position as a Director, in February of 1996; Thomas G. Wiley,
from his position as a Director, in March of 1996; Thomas V. Baker, from the
positions of Chief Financial Officer, Secretary and Director, in January of
1997; and Errol Ginsberg, from his position as Vice President of Engineering,
in March of 1997. There are currently two vacancies on the Company's five-
person Board of Directors.
 
  The Company's success depends to a significant degree upon the continued
contributions of its existing key management, sales, marketing, research and
development and manufacturing personnel, many of whom would be difficult to
replace. If certain of these employees were to leave, the Company could be
materially and adversely effected. The Company believes its future success
will also depend largely upon its ability to attract and retain highly skilled
software and hardware engineers, managerial, and sales and marketing
personnel. Competition for such personnel is intense, and there can be no
assurance that the Company will be successful in attracting and retaining the
necessary personnel.
 
 Risks Associated with Intellectual Property
 
  The Company regards its products as proprietary and relies primarily on a
combination of statutory and common law copyright, trademark, trade secret
laws, customer licensing agreements, employee and third-party nondisclosure
agreements and other methods to protect its proprietary rights. The Company
generally enters into confidentiality and invention assignment agreements with
its employees and consultants. Additionally, the Company enters into
confidentiality agreements with certain of its customers and potential
customers and limits access to, and distribution of, its proprietary
information. Despite these precautions, it may be possible for a third party
to copy or otherwise obtain and use the Company's technologies without
authorization, or to develop similar technologies independently. If
unauthorized use or misuse of the Company's products were to occur to any
substantial degree, the Company's business, financial condition and results of
operations could be materially adversely affected. There can be no assurance
that the Company's means of protecting its proprietary rights will be adequate
or that the Company's competitors will not independently develop similar
technology.
 
  While the Company has not received claims alleging infringement of the
proprietary rights of third parties which the Company believes would have a
material adverse effect on the Company's business, financial condition or
results of operations, nor is it aware of any similarly threatened claims,
there can be no assurance that third parties will not claim that the Company's
current or future products infringe the proprietary rights of others. Any such
claim, with or without merit, could result in costly litigation or might
require the Company to enter into royalty or licensing agreements. Such
royalty or licensing agreements, if required, may not be available on terms
acceptable to the Company, or at all.
 
 Fluctuations in Market Price of the Company's Securities
 
  The Company's securities have experienced significant price volatility and
such volatility may occur in the future, particularly as a result of quarter-
to-quarter variations in the actual or anticipated financial results of the
 
                                       8
<PAGE>
 
Company or of other companies in the industry or announcements by the Company
or its competitors regarding new product introductions or other developments
affecting the Company. In addition, the market has experienced extreme price
and volume fluctuations that have affected the market price of many technology
companies' stocks and that have been unrelated or disproportionate to the
operating performance of these companies. These broad market fluctuations may
adversely affect the price of the Company's securities.
 
EMPLOYEES
 
  As of December 31, 1996, the Company employed 51 persons, of whom 30 were
primarily engaged in engineering and engineering services, 9 in manufacturing
and quality assurance, 7 in sales, marketing, customer support and related
activities, and 5 in administration. None of the Company's employees is
currently represented by a labor union.
 
ITEM 2. PROPERTIES.
 
  The Company's principal offices are located at 201 Continental Blvd., Suite
201, El Segundo, California, consisting of approximately 12,000 square feet of
office space under a five-year lease expiring in May 2001. In November 1996,
the Company signed a two-year lease for 1613 square feet of office space in
Sunnyvale, California. In December 1996, the Company also signed a three-year
lease agreement for 750 square feet of office space in Allentown,
Pennsylvania. Total annual rent for the Company is approximately $271,000.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
        RESULTS OF OPERATIONS.
 
GENERAL
 
  This Management's Discussion and Analysis of Financial Condition and Results
of Operations contains forward-looking statements that involve certain risks
and uncertainties that could cause actual results to differ materially from
those in the forward-looking statements. Potential risks and uncertainties
include, without limitation, those mentioned in this report and in particular
included in "Risk Factors."
 
  In mid-1994, the Company introduced its 8 port Ethernet switch and began
commercial shipments of this product in late 1994. In 1995, the Company
attempted to market this product both through distribution channels and to
Original Equipment Manufacturers ("OEMs"). Late in the third quarter of 1995,
the Company changed its strategic marketing emphasis to OEM customers and
discontinued its efforts to market through distribution channels. In the first
quarter of 1996, the Company completed its second product, a 16 port Ethernet
switch with uplink capability. In the first quarter of 1996, the production
and sale of the original 8 port product was discontinued. During the third
quarter of 1996, the Company began selling an 8 port Ethernet switch with a
100 Base T uplink. Substantially all of the revenue in 1996 is from the 8 and
16 port Ethernet switching products including 100 Base T, 100 Base FX and 100
VG uplinks. Year end comparisons with 1995 and 1994 are not generally
meaningful due to the strategic shift in the Company's sales and marketing
activities and the introduction in 1996 of the 16 port Ethernet switch
products.
 
RESULTS OF OPERATIONS
 
  During the year ended December 31, 1996, the Company had net revenues of
$26,427,427 for sales of 8 and 16 port Ethernet switch products compared with
$1,262,745 from sales of 8 port products for the year ended December 31, 1995.
Net revenues for 1994 amounted to $120,102. Revenues have increased from 1994
to 1995 by 951% and from 1995 to 1996 by 2000%. The increase in sales for 1996
was attributable to the Company's shift in sales strategy to concentrate on
sales to OEMs, and to continued introduction by the Company of additional
features and functions to its products and to substantial growth in the LAN
switching market.
 
  The Company has achieved rapid growth in revenues from year to year;
however, the Company does not anticipate the ability to sustain this rate of
revenue growth in future years.
 
  Comparisons to the 1995 and 1994 years are not meaningful due to the
strategic shift in the Company's sales and marketing activities as well as the
discontinuation in 1996 of the product which accounted for the 1995 and 1994
revenues.
 
  Cost of revenue for the year ended December 31, 1996 of $23,096,871 includes
an adjustment recorded in the fourth quarter of $1,050,000, which related to a
one-time reduction in inventory value thus resulting in a higher cost of
sales. Cost of revenue for the twelve months ended December 31, 1996 was 87%
of revenue compared with 115% and 67% in 1995 and 1994, respectively. Gross
profit margin was 13% for 1996 compared with a negative 15% for 1995 and 33%
for 1994. The increase in gross margin in 1996 was primarily attributable to
sales volumes, design changes and component cost reductions. The negative
gross margin for 1995 was attributable to an inventory adjustment for the
carrying value of finished product in inventory, for a product which was
discontinued, and to declines in the average selling prices due to competitive
market pressures. The gross margin for 1994 was 33% due to product being sold
directly to customers and not through OEMs.
 
  In the future, the Company's gross margins may be affected by several
factors, including the mix of products sold, the price of products sold, price
competition, manufacturing volumes, fluctuations in material costs, changes in
other components of cost of sales and the technological innovativeness of
products sold. Timing and new product introductions may impact gross margins
and result in excess or obsolete inventories.
 
  Research and development expenses increased $2,120,391, or 97%, to
$4,312,927 in the twelve months ended December 31, 1996 compared with the
twelve months ended December 31, 1995. The 1994 expenses
 
                                      12
<PAGE>
 
amounted to $847,872. The 1996 increase in research and development expenses
is attributed to the addition of engineering staff and payments for consulting
services in connection with the development of existing and new products. See
"Risk Factors--Product Development and Timely Introduction of New and Enhanced
Products." The increase is also attributable to the Company's belief that its
future success depends on a high level of research and development and its
ability to attract and retain highly skilled software and hardware engineers.
 
  Marketing and selling expenses increased by $974,654, or 70%, to $2,369,503
for the twelve months ended December 31, 1996 compared with total expenses of
$1,394,849 in 1995 and $149,249 in 1994. These increases in expenses were due
to the addition of sales, marketing and technical support personnel. The
growth in personnel was primarily due to the need to manage the activities of
an increased number of OEM customers and the introduction of new products.
Incentive commission rates were in effect in 1996 for performance in excess of
sales levels projected at the beginning of the year. Revenues in excess of the
plan resulted in high commissions. Commissions, as a percentage of revenues,
in 1997 are expected to decline.
 
  General and administrative expenses increased $794,153, or 53%, to
$2,288,374 for the year ended December 31, 1996, compared with total expenses
of $1,494,221 for 1995. General and administrative expenses for 1994 totaled
$833,533. In 1996, administration bonus costs for achievements attained and
increased legal costs indirectly associated with the redemption of the
warrants, accounted for 2% and 14%, respectively, of such expenses. Insurance,
primarily directors' and officers' insurance, accounted for approximately 21%
of the increase and depreciation expenses accounted for approximately 13% of
the increase. Increases are also attributable to the addition of personnel,
consultants and the costs applicable to the implementation and training of
staff on a fully integrated computerized accounting system.
 
  Interest income was $91,827 for 1996 compared with $79,566 for 1995 and
$5,203 for 1994, due to higher cash balances when proceeds from the initial
public offering in 1995 and warrant exercises in 1996 were invested in
interest bearing instruments.
 
  Interest expense increased $43,700, or 17%, to $294,190 in 1996, compared
with $250,490 in 1995. Interest expense for 1994 was $57,651. This increase is
the result of the interest expense of $191,326, or 65%, which represents
interest and warrant costs associated with loans to the Company. Currently,
the Company has no debt.
 
  The net loss for 1996 was $9,896,537, which includes a non-cash charge of
$4.2 million for the release of certain escrowed common shares, and a one-time
reduction to the value of inventory of $1.1 million, which resulted in a
higher cost of sales, resulting in a $2.23 loss per share. The loss before
extraordinary item for 1995 was $6,028,512 or $3.47 loss per share compared
with a loss of $1,843,200 or $3.47 pro forma loss per share for the year ended
December 31, 1994. In 1995, the extraordinary item added an additional loss of
$474,231 or $0.27 per share; thus resulting in a loss of $3.75 per share for
the year. A similar item did not exist in 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since its inception in March 1991, the Company has financed its development
activities through a combination of an initial public offering completed in
1995 and private transactions involving the issuance of common stock for cash,
convertible notes, bridge notes and the exercise of stock options and
warrants. For the period from March 12, 1991 (inception) to December 31, 1996,
the Company has raised $39,108,077 from such sources.
 
  At December 31, 1996, the Company had working capital of $15,603,714,
including inventory of $7,440,038. At December 31, 1996 the Company had
$2,787,593 in cash. The Company requires substantial working capital to fund
its business, particularly to finance inventories and accounts receivable
(which are increasing in connection with increased product sales) and for
capital expenditure. The Company's future capital requirements will depend on
many factors, including the rate of revenue growth, the timing and extent of
spending to support product development efforts and expansion of sales and
marketing, the timing of introductions of new products and enhancements to
existing products, and market acceptance of the Company's products.
 
                                      13
<PAGE>
 
  On January 10, 1996, the Company completed a private sale of 854,993 shares
of its Class A Common Stock to two individuals for total net proceeds of
$5,000,000. In 1996 and January 1997, the Company completed calls of Class A
and Class B Warrants resulting in the receipt of $17,368,000 and $27,000,000,
respectively.
 
  The Company believes that its existing cash and the unused bank line of
credit are sufficient to meet the liquidity requirements of the Company at
least for the current year. However, because of the rapid growth in revenues,
continuing investments in research and development and operating losses, the
Company may need to seek additional credit, alternative financing and/or
further equity investment. The sources of such credit or equity investment may
include increased lines of credit and/or issuance of additional securities.
There can be no assurance, however, that additional funds from equity or debt
sources will be available on favorable terms or at all. The Company's future
capital requirements will depend upon numerous factors, including the progress
of the Company's cost reduction efforts for its existing products, the success
or lack thereof of its new product development, the amount of resources
devoted to manufacturing and marketing, technological advances, the status of
competitors and the success or lack thereof of the Company's marketing
activities.
 
  In July 1996, the Company secured a revolving line of credit with a bank,
which provides for borrowings of up to $5,000,000. Borrowings under the line
of credit bear interest at the bank's prime rate plus 2%. The line of credit
expires in June 1997. The line of credit agreement requires the Company to
comply with certain financial covenants. The line of credit is currently
unused.

                         NOTES TO FINANCIAL STATEMENTS
 
                          DECEMBER 31, 1996 AND 1995
 
NOTE 1--THE COMPANY
 
  NetVantage, Inc. ("NetVantage" or the "Company") is a leading provider of
Ethernet Workgroup switching products designed to increase the information
handling capacity of new and installed Local Area Networks or "LANs." Other
applications of use for the Company's switching products include connecting
LANs to each other to extend the network's scope and power and to provide
installed networks with the ability to connect to networking devices
incorporating new technologies such as Asynchronous Transfer Mode or "ATM,"
and Gigabit Ethernet. The Company's switching products require no special
skills to install, and require no changes to existing user network equipment,
wiring, hub equipment, software protocols or applications.
 
SALES TO MAJOR CUSTOMERS
 
  Sales to the three major customers amounted to $8,003,350 (31%), $5,712,598
(22%) and $3,773,259 (14%) in 1996 and sales to the three major customers
amounted to $256,173 (20%), $254,705 (20%) and $206,454 (16%) in 1995. Sales
were not to the same major customers in 1996 and 1995.
 
NOTE 2--SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
USE OF ESTIMATES
 
  The preparation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities and
disclosures in the financial statements. Actual results could differ from
those estimates.
 
DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS
 
  The carrying amount of all financial instruments comprising cash,
receivables, prepaids, accounts payable, accrued expenses and amounts due to
related parties approximate fair value because of the short maturities of
these instruments.
 
REVENUES
 
  Revenue from shipments to Original Equipment Manufacturers ("OEMs") is
recognized upon shipment.
 
INVENTORIES
 
  Inventories are stated at the lower of cost or market. Cost is determined on
the first-in, first-out method.
 
DEFERRED WARRANT CALL COSTS
 
  Costs incurred directly related to the Company's Class B Warrant redemption
(see Note 9) were capitalized. In January 1997, these costs will be offset
against the proceeds received and charged to stockholders' equity.
 
PROPERTY, PLANT AND EQUIPMENT
 
  Property, plant and equipment are carried at cost less accumulated
depreciation and amortization. Depreciation on property, plant and equipment
is computed using the straight-line method over the estimated useful lives,
which range from three to four years. Expenditures for ordinary repairs and
maintenance are charged to expense as incurred.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
                          DECEMBER 31, 1996 AND 1995
 
 
INTANGIBLES
 
  Goodwill and other intangibles are amortized over their estimated useful
lives which range from one to five years.
 
RESEARCH AND DEVELOPMENT COSTS
 
  Research and development costs are expensed as incurred.
 
INCOME TAXES
 
  Income taxes are determined under guidelines prescribed by Financial
Accounting Standards Board Statement No. 109 ("FAS 109"), "Accounting for
Income Taxes". Under FAS No. 109, deferred income taxes are recognized for the
tax consequences in future years of temporary differences between the tax
bases of assets and liabilities and their financial reporting amounts.
Valuation allowances are established when necessary to reduce deferred tax
assets to the amount expected to be realized. At December 31, 1996 and 1995
temporary differences consist primarily of net operating loss carry forwards
("NOLs") and tax credits. At December 31, 1996, the Company has NOLs to carry
forward for federal purposes of $15 million and for California purposes of
$7.1 million and has generated tax credits for certain research and
development activities of $366,800 and $146,700 for federal and state
purposes, respectively. The NOLs and research and development credits expire
from 2006 to 2011. A valuation allowance of $6.3 million has been provided for
the entire amount of the net deferred tax assets, which represents an increase
in the valuation allowance of $4.2 million from December 31, 1995.
 
  The Company's ability to use its NOLs to offset income may be subject to
restrictions enacted in the United States Internal Revenue Code of 1986, as
amended (the "Code"). These restrictions could limit the Company's use of its
NOLs as a result of certain stock ownership changes described in the Code,
which would include transactions such as the Company's initial public
offering, private placement of common stock and other equity transactions.
 
CONCENTRATION OF CREDIT RISK
 
  Financial instruments which subject the Company to concentration of credit
risk consist primarily of accounts receivable. The risk associated with
accounts receivable is limited by the large size and credit worthiness of the
Company's commercial customers.
 
  The Company has recorded an allowance for doubtful accounts and will
continue to adjust this allowance periodically based upon the Company's
evaluation of historical loss experience, industry trends and other related
factors.
 
ADOPTION OF RECENTLY ISSUED ACCOUNTING STANDARDS
 
  Effective January 1, 1996 the Company adopted a method of accounting for
stock-based compensation plans as required by Statement of Financial
Accounting Standard No. 123 (FAS 123). FAS 123 allows for two methods of
valuing stock based compensation. The first method allows for the continuing
application of APB 25 in measuring stock based compensation, while complying
with the disclosure requirements of FAS 123. The second method uses an option
pricing model to value stock compensation and record as such within the
financial statements. The Company will continue to apply APB 25, while
complying with FAS 123 disclosure requirements (see Note 10).

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
                          DECEMBER 31, 1996 AND 1995
 
 
NET LOSS PER SHARE
 
  Net loss per share was computed based on the weighted average number of the
Company's common shares outstanding during 1996 and excludes the shares of
Class E Common Stock held in escrow because the conditions for the release of
these shares from escrow have not been satisfied. Common Stock equivalents
were not considered in the net loss per share calculation in 1996 and 1995
because the effect on the net loss would be antidilutive.
 
PRO FORMA NET LOSS PER SHARE
 
  The pro forma net loss per share for 1994 was computed based on the weighted
average number of shares of common stock outstanding during 1994, after giving
retroactive effect to the conversion of the convertible notes, and excludes
all shares of Class E Common Stock outstanding, or subject to option, held in
escrow because the conditions for the release of shares from escrow had not
been satisfied. All Class B and Class E Stock options and warrants granted and
Class A and Class B Common Stock issued during the twelve months preceding the
May 1995 public offering have been included as outstanding for the entire
period using the treasury stock method and the public offering price per
share.
 
NOTE 3--PUBLIC OFFERING
 
  On May 3, 1995 the Company completed an initial public offering of 1,725,000
units (including the underwriter's overallotment of 225,000 units). Each unit
comprises one share of the Company's Class A Common Stock, one Class A Warrant
and one Class B Warrant (the "Units"). Upon exercise, the Class A Warrants
entitled the holder to purchase one share of Class A Common Stock for $6.50
and receive one Class B Warrant. Class B Warrants entitled the holder to
purchase one share of Class A Common Stock for $7.75. The offering price was
$5.00 per Unit for total gross proceeds of $8,625,000 or $7,503,750 after the
underwriter's commission.
 
  In accordance with the Warrant Agreement between the Company and the
underwriter, the original exercise price and number of securities issuable
upon the exercise of the Class A Warrants were adjusted to $6.21 and 1.05
shares, respectively, and the original exercise price and number of securities
issuable upon the exercise of the Class B Warrants were adjusted to $7.41 and
1.05 shares, respectively.
 
  As part of the public offering, the Company agreed to (i) issue an option to
the underwriter to purchase additional Units equal to 10% of the Units offered
to the public at a price equal to 120% of the initial public offering price
("Unit Purchase Option"), (ii) pay certain fees and expenses including the
cost of registration of the Unit Purchase Option, and/or the underlying
securities and (iii) certain other covenants. As of the date of this filing,
the underwriter has not exercised its rights under this option.
 
  As a condition of the initial public offering, the underwriter required that
all shares of the Company's Class B and Class E Common Stock and all shares of
Class B and Class E Common Stock issuable upon exercise of outstanding options
from the 1992 Stock Option Plan be subject to an escrow agreement. The Class B
Common Stock and related options were released from escrow on June 3, 1996. A
total of 541,062 Class E Common Stock and related options were released from
escrow on October 17, 1996, upon the achievement of certain earnings levels or
market price targets. The release of these shares resulted in a compensatory
non-cash charge to earnings for the fourth quarter of 1996 (see Notes 9 and
13). At December 31, 1996, 540,995 shares of Class E Common Stock remain in
escrow and are subject to release upon the attainment of certain specified
earnings levels or market price targets.

                          DECEMBER 31, 1996 AND 1995
 
NOTE 4--NOTES PAYABLE
 
  In July 1996, the Company secured a $5,000,000 revolving bank line of credit
which bears interest at prime rate plus 2% and expires in June 1997. In
connection with this line of credit, the Company issued two warrants. Each
warrant entitles the bank to purchase 30,000 shares of the Company's Class A
Common Stock at an exercise price of $9.875 and $11.44 per share,
respectively. The two warrants were exercisable immediately and expire on July
15, 2001 and August 16, 2001, respectively. This credit facility requires the
Company to comply with certain financial covenants. The Company is in
compliance with these covenants as of December 31, 1996. As of December 31,
1996, the line of credit is unused.
 
  In June 1996, NextCom K.K. ("NextCom"), a customer of the Company whose
former president also serves on the Company's Board of Directors, advanced
$500,000 to the Company. In lieu of interest expense, NextCom received an
additional 5% discount on all Company purchases until the advance was paid
off. The advance was repaid in October 1996 (see Note 5).
 
  In January 1995, the Company completed a private placement of $1,000,000 in
promissory notes through the underwriter of its initial public offering which
acted as placement agent. The notes bore interest at the rate of 10% per annum
and were payable from the proceeds of the public offering. As of December 31,
1994, $600,000 of such notes were issued. In connection with this loan, the
placement agent received a commission and a non-accountable expense allowance
of 10% and 3%, respectively, amounting to $130,000, of which $78,000 pertains
to the notes issued in December 1994. These debt issue costs were amortized to
income over the term of the loan.
 
  In addition, the Company issued warrants to these investors which entitle
them to purchase an aggregate of 500,000 shares of the Company's Class A
Common Stock at $3.00 per share. The warrants expire in 1999. The aggregate
value of all warrants, $575,000, was considered additional debt discount which
was amortized to income as interest over the term of the loan. The warrants
pertaining to the portion of notes issued in December 1994 were valued at
$345,000. Upon the closing of the public offering, the warrants automatically
converted to Class A Warrants in all respects.
 
  Upon the closing of the public offering in May 1995, the promissory notes
were paid in full. As a result, the $474,231 unamortized portion of debt issue
costs and debt discount was charged to income as an extraordinary item.
 
  In connection with the bridge financing, the Company also entered into an
agreement with the placement agent that provides for a finder's fee to be paid
to the placement agent if it originates a financing, merger, acquisition,
joint venture, or other similar transaction to which the Company is a party,
during the five-year period from the consummation of the initial public
offering. The fee is based on a declining percentage of the consideration paid
in the transaction, beginning at 7% of the first $1,000,000.
 
  In June 1994, the Company issued $482,000 of 5% redeemable, subordinated
convertible notes with detachable warrants. The Company recorded the fair
market value of the detachable warrants ($188,800) as additional debt
discount. All outstanding convertible notes were converted September 30, 1994.
 
NOTE 5--RELATED PARTY TRANSACTIONS
 
  Certain officers and directors of the Company have provided services to the
Company under consulting arrangements which permitted either party to
terminate the services at will without further obligation. For the years ended
December 31, 1995 and 1994, expenses charged to operations for consulting
services rendered by

                          DECEMBER 31, 1996 AND 1995
 
these officers and directors were $19,214 and $129,652, respectively. The
Company did not engage officers or directors under consulting arrangements
during 1996.
 
  Related parties are employed by the Company under existing employment and
sales commissions agreements. Amounts included in marketing and selling
expense for these employees were $500,000 as of December 31, 1996.
 
  The amounts due to employees and consultants were $342,505 and $18,479 at
December 31, 1996 and 1995, respectively.
 
  The amounts due from employees and consultants was $100,000 at December 31,
1996. There were no amounts due from employees and consultants in 1995.
 
  An officer of the Company has from time to time advanced money to the
Company to fund operations. In lieu of interest, the officer was issued two
warrants. These warrants entitle the officer to purchase 11,765 and 11,110
shares of Class A Common Stock at an exercise price of $8.50 and $9.00 per
share, respectively. Both warrants are exercisable immediately and expire in
October 2001. The fair value of these warrants was amortized as interest
expense during 1996.
 
  On May 27, 1996, the Company issued two warrants to an officer under the
terms of his 1996 Employment Agreement for consideration of $300. One warrant
entitles the officer to purchase 15,000 shares of Class A Common Stock at an
exercise price of $7.125 per share. This warrant became exercisable on October
17, 1996, the date the first half of the outstanding Class E Shares were
converted to Class B Common Stock. The other warrant entitles the officer to
purchase 15,000 of Class A Common Stock at a price of $7.125 per share. This
warrant is exercisable when the remaining Class E Shares are converted to
Class B Common Stock. The warrants terminate on January 1, 1999.
 
  In January 1996, the Company completed a private sale of 854,993
unregistered and previously unissued shares of its Class A Common Stock to two
private investors for net proceeds of $5,000,000. One of the private investors
is a member of the Company's Board of Directors.
 
  During 1996, a member of the Company's Board of Directors was the President
of NextCom. In 1996 the Company had sales to NextCom of $1.5 million (6% of
total 1996 revenue). There were no sales to NextCom in 1995.
 
  In June 1996, NextCom advanced $500,000 to the Company. In lieu of interest

NOTE 9--STOCKHOLDERS' EQUITY
 
COMMON STOCK
 
  The Class A, Class B and Class E Common Stock are substantially the same on
a share-for-share basis, except that (i) the holder of an outstanding share of
Class A Common Stock is entitled to one vote and the holder of an outstanding
share of Class B or Class E Common Stock is entitled to five votes; (ii) Class
B and Class E Common Stock are not freely transferable; and (iii) Class E
Common Stock is not entitled to corporate dividends or distributions and may
be redeemed by the Company after March 31, 1999 for $0.01 per share. All
shares of Class B Common Stock that were previously placed into escrow were
released on June 3, 1996. Each share of Class B Common Stock may be converted
at any time, at the option of the holder, into one share of Class A Common
Stock. Each share of Class E Common Stock is convertible into one share of
Class B Common Stock in the event that certain targets are met. See "Class E
Escrow Arrangement."
 
  At September 30, 1994, holders of warrants to purchase 98,500 shares of
Class B Common Stock and 197,001 shares of Class E Common Stock exercised
their warrants. As consideration, the Company received cash of $531,110 and
relief of amounts due to related parties of $472,114.
 
  On September 30, 1994 the holders of $1,234,749 of convertible debt,
representing all remaining convertible debt along with accrued interest of
$60,304, converted their holdings into 86,337 shares of Class B Common Stock
and 172,674 shares of Class E Common Stock.
 
CLASS E ESCROW ARRANGEMENT
 
  In connection with the public offering of the Units (see Note 3), all
outstanding shares of Class E Common Stock were placed in escrow by existing
stockholders. All shares of Class E Common Stock placed into escrow, including
those shares which may be issued upon exercise of options ("Escrowed
Contingent Shares") are not transferable (but those issued and outstanding may
be voted).
 
  These shares are to be released from escrow in the event that net income
before provision for income taxes, and exclusive of any extraordinary earnings
or charges and the compensation charges discussed in the next paragraph,
reaches certain targets during the next three years (the first 600,000 shares
will be released if pretax income exceeds $4.3 million, $5.8 million or $7.2
million in fiscal years 1996, 1997 or 1998, respectively, and the remaining
600,000 will be released if pretax income exceeds $5.3 million, $7.1 million,
or $8.9 million in fiscal years 1996, 1997 or 1998, respectively); or the
market price of the common stock reaches specified levels over the next three
years (the first 600,000 shares will be released if, commencing at May 3, 1995
and ending November 3, 1996, the bid price of the Company's common stock
averages in excess of $13.33 per share for 30 consecutive business days, or
commencing November 3, 1996 and ending May 3, 1998, the bid price averages
$16.67 per share for 30 consecutive business days and the remaining 600,000
shares will be released if, commencing at May 3, 1995 and ending November 3,
1996, the bid price of the Company's common stock averages in excess of $18.50
per share for 30 consecutive business days or commencing November 3, 1996 and
ending May 3, 1998, the bid price averages in excess of $23.50 for 30
consecutive business days). Any options to purchase common stock shall be
deemed converted into similar options to acquire Class B and Class E Common
Stock in the same proportion that outstanding Class E Common Stock is
converted upon attaining the specified earnings or market price levels.
 
  On October 17, 1996, the criteria for the release of certain Escrowed
Contingent Shares were met and on that date 600,000 shares, including 541,062
shares held by employees, officers, directors, consultants and their
relatives, were released from escrow. The release of 541,062 shares was deemed
compensatory and, accordingly,

                          DECEMBER 31, 1996 AND 1995
 
resulted in a current year charge to earnings equal to the fair market value
of the Escrowed Contingent Shares on release.
 
  The release of Escrowed Contingent Shares held by individuals that have not
had any relationship with the Company, other than that of a common
stockholder, have been deemed not to be compensatory.
 
  All Escrowed Contingent Shares that have not been released from escrow by
March 31, 1999 are subject to redemption by the Company at a redemption price
of $0.01 per share.
 
WARRANTS
 
  On October 24, 1996, the Company completed the redemption of its Class A
Warrants which resulted in the exercise of 99.9% of the Class A Warrants and
the issuance of 2,335,568 shares of Class A Common Stock and the same number
of Class B Warrants. In addition, as of October 24, 1996, Class B Warrants to
purchase 368,360 shares were voluntarily exercised, resulting in the issuance
of 386,778 shares of Class A Common Stock. Total proceeds from the exercise of
all Class A and Class B Warrants on October 24, 1996 was approximately
$17,368,000. On November 3, 1996, the Company repaid the bank line of credit
from the proceeds received from the issuance of the Class A Warrants.
 
  The Company redeemed its Class B Warrants on January 10, 1997, pursuant to
its November 27, 1996 notice of redemption. Prior to the redemption date,
approximately $3.5 million or greater than 99% of the outstanding Class B
Warrants were exercised, resulting in gross proceeds to the Company of
approximately $27,000,000. After the warrant exercise, approximately 9.4
million shares of Class A Common Stock were outstanding.

mutual agreement with the warrant holders. To induce the warrant holders to
exercise their warrants, the Company offered all warrant holders the
opportunity to reduce the exercise price of their warrants by 20%.
 
  The Company recorded additional charges against operations representing the
difference between the exercise price and the expected initial public offering
price, less amounts previously recorded. The additional compensation of
$127,820 related to additional lease costs. Also, the shares of Class B Common
Stock issued in these transactions at prices less than the initial public
offering price have been included in the calculation of weighted average
shares outstanding used in the calculation of the 1994 pro forma net loss per
share as if they were outstanding for all periods.

  These pro forma amounts may not be representative of future disclosures
since the estimated fair value of stock options is amortized to expense over
the vesting period, and additional options may be granted in future years. The
fair value for these options was estimated at the date of grant using the
Black-Scholes option pricing model with the following assumptions for 1996 and
1995, respectively: Dividend yields of 0%; average annual volatility of 40% to
50%; risk free interest rates of 5.9% to 6.9%; and expected lives of 3 to 5
years for both periods. The weighted average fair value of options granted
during 1996 and 1995 for which the exercise price equals the market price on
the grant date was $3.9 million and $900,000, respectively.
 
  The Black-Scholes model was developed for use in estimating the fair value
of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including the expected stock price and volatility.
Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in

subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a
reliable single measure of the fair value of employee stock options.

NOTE 12--STRATEGIC ALLIANCE AGREEMENT WITH CIRCUITPATH
 
  In January 1995, the Company entered into a Strategic Alliance Agreement
with CircuitPath Network Systems Corporation ("CircuitPath") which provides
each party with a license to certain technologies and information of the other
party. The Company received, for a payment of $580,000 in May 1995, a two-year
exclusive license to certain CircuitPath core technologies and intellectual
property, and a perpetual license to any enhancements made by the Company
during the initial two-year period. No Circuitpath technology has been
incorporated into any of the Company's products nor is any such incorporation
contemplated in the future.
 
NOTE 13--FOURTH QUARTER ADJUSTMENTS
 
  In the quarter ended December 31, 1996 the Company recorded a $1 million
adjustment to decrease the value of remaining inventory to reflect
management's estimate of its current market value. The Company also recorded a
$4,082,055 adjustment to record the non-cash charge to compensation expense
for the October 1996 release of 541,062 shares of Class E Common Stock from

                          DECEMBER 31, 1996 AND 1995
 
 
  In the quarter ended December 31, 1995 the Company recorded an adjustment
for its inventory of finished products in the amount of $400,660, which
reflects management's estimate of the current market value for the units
remaining in inventory. The adjustment, in management's opinion, reflects the
competitive pressures on selling prices of similar products which occurred in
the fourth quarter of 1995 and the first two months of 1996. In early 1996,
the Company decided to halt further development of the Token Ring switch and
focus the Company's resources on the Ethernet switching market. As a result an
adjustment was recorded in the fourth quarter in the amount of $210,000
representing the carrying value of Token Ring inventory. The Company recorded
a further adjustment, in the fourth quarter of 1995 of $150,426 for a chip
that was made obsolete by a recently released updated version of the device
which operates at a higher speed.

(1) Amounts do not include certain warrants granted to Mr. Rizzone and options
    granted to Mrs. Rizzone. See Note 5 to Summary Compensation Table and
    "Certain Relationships and Related Transactions."
(2) Options to purchase Class A Common Stock granted under the 1994 Plan and

(4) Options to purchase Class B Common Stock and Class E Common Stock (of
    which one-third of such shares are Class B Common Stock and two-thirds of
    such shares are Class E Common Stock) granted under the Company's 1992
    Incentive and Nonstatutory Stock Option Plan (the "1992 Plan") are
    exercisable at the rate of one-third each year and are subject to earlier
    termination in the event the employee is no longer employed by the
    Company.
(5) The market price for options to purchase Class A Common Stock was set at
    the average of the bid and ask prices of the Class A Common Stock on the
    applicable date as reported by Nasdaq. Due to certain restrictions on the
    transferability of the underlying shares, the market price for options to
    purchase Class B and Class E Common Stock was set at 80% of the average of
    the bid and ask prices of the Class A Common Stock on the applicable date
    as reported by Nasdaq.
(6) Potential gains are net of the exercise price but before taxes associated
    with the exercise. Amounts represent hypothetical gains that could be
    achieved for the respective options if exercised at the end of the option
    term. The assumed 0% (in the case of options granted at an exercise price
    below market price), 5% and 10% rates of stock price appreciation are
    provided in accordance with the rules of the Securities and Exchange
    Commission and do not represent the Company's estimate or projection of
    the future market price of the Common Stock. Actual gains, if any, on
    stock option exercises are dependent on the future financial performance
    of the Company, overall market conditions and the option holders'
    continued employment through the vesting period.
(7) Amounts shown reflect the options granted to Mr. Baker as of December 31,
    1996 and assume expiration on the dates indicated in the table; however,

    employment ceased on January 22, 1997.
(8) Amounts shown reflect the options granted to Mr. Ginsberg as of December
    31, 1996 and assume expiration on the dates indicated in the table;
    however, by their terms, such options are subject to earlier termination
    in the event Mr. Ginsberg is no longer employed by the Company. Mr.
    Ginsberg's employment ceased on March 18, 1997.

EMPLOYMENT AND SEVERANCE AGREEMENTS AND ARRANGEMENTS
 
  The Company has an employment agreement with Stephen Rizzone effective as of
January 1, 1997, as amended, providing for his employment as Chairman of the
Board, President and Chief Executive Officer through December 31, 2001, at an
initial base salary of $200,000 per year commencing January 1, 1997, and such
other incentive compensation as is consistent with industry practice, subject
to review annually by the Board. The agreement also provides for the grant of
additional options to purchase Common Stock, the use of a leased automobile
and certain other benefits. The agreement may be terminated by either party
with or without cause on 30 days written notice. In the event the Company
terminates Mr. Rizzone's employment, either with or without cause at any time,
for any reason, or Mr. Rizzone terminates his employment due to (i) a change
in duties, title or responsibility of his position, (ii) a removal from or
non-election to the Board or from the position of Chairman of the Board, (iii)
a change affecting Mr. Rizzone's position in organizational structure of the
Company, (iv) a reduction in compensation, (v) an increase in travel required
to the principal offices of the Company greater than fifty miles or (vi) an

termination benefits. Such benefits will include the following: (a) his salary
and benefits will continue for a period of thirty-six months from the date of
termination, (b) payment will be made for accrued and unused vacation time
vested as of the date of termination, (c) stock options granted prior to
termination will vest and be exercisable for a period of thirty-six months,
and (d) the cash bonus discussed below will be paid, effective for 48 months
after termination. In the event of a "Reorganization" (as defined in the
agreement), Mr. Rizzone is entitled to a cash bonus based on the total
consideration to be paid in the Reorganization divided by the number of shares
of Class A Common Stock outstanding at the time of the Reorganization, such
that if the resulting price per share is $15 or less, he will receive a bonus
equal to 2% of the total consideration; if the resulting price per share is
greater than $15 but less than $20, the bonus will equal 3% of the total
consideration; and if the resulting price per share is $20 or more, the bonus
will equal 4% of the total consideration. He is also entitled to receive such
bonus up to 12 months after his voluntary termination.
 
  The Company has an employment agreement with George Pontiakos which provides
for an initial base salary of $120,000 per year (which has been currently
adjusted to $150,000), eligibility for quarterly and annual bonuses ranging
from 5% to 15% of base salary, and certain other benefits. In the event Mr.
Pontiakos' employment is terminated for any reason, other than cause, he is
entitled to a severance, at his base salary amount for six months. The Company
is not obligated to provide any severance to Mr. Pontiakos should he
voluntarily resign his position. In addition, if the current Chief Executive
Officer is removed from his position, Mr. Pontiakos will have the option of
resigning from the Company and receiving twelve months of severance at his
base salary. Aubrey Brown also has a similar option to resign and receive
twelve months of severance at his base salary (which is currently $180,000) in
the event the current Chief Executive Officer is removed from his position.
 
  The Company had an employment agreement with Errol Ginsberg which provided
for a base salary of $150,000 per year and certain other benefits. In the
event Mr. Ginsberg is terminated for any reason, other than cause, he is
entitled to severance at his base salary for one year provided he does not
violate any terms of his confidentiality agreement with the Company. The
Company is not obligated to provide any severance to Mr. Ginsberg should he
voluntarily resign his position.
 
  The Company had an employment agreement with Thomas Baker which provided for
an initial base salary of $80,000 which was increased from time to time by the
Company. The agreement also provided for incentive compensation based on the
Company achieving certain enumerated performance goals and as determined to be
fair and reasonable by the Compensation Committee of the Board of Directors.
The agreement further provided that in the event the employee's employment was
terminated by the Company at any time for any reason other than cause,
disability, death or upon the employees' voluntary termination, or by
termination of the employee (or reduction in statute, nature of duties,
employee benefits or working conditions from those enjoyed by all other
executives at the same level or higher) within 120 days following a "Change of
Control" of the Company, the Company would pay the employee an amount equal to
the sum of (i) the employee's accrued but unpaid base salary, and one year's
base salary at the employee's then prevailing base salary; (ii) all accrued
and unpaid vacation pay as of his termination date; and (iii) all accrued and
unpaid incentive compensation through the most recent date prior to
termination for which such incentive compensation would be calculated.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.
 
  Mr. Rizzone, the Company's Chairman of the Board, Chief Executive Officer
and President is married to Mashid Rizzone, the Company's Director of Sales,
who is separately compensated by the Company. See Notes 4 and 5 to "Executive
Compensation--Summary Compensation Table." In early 1997, the Company made an
advance against future commissions to Mrs. Rizzone of approximately $255,000,
and an advance against future compensation to Mr. Rizzone of $100,000, which
the Company has recorded in 1997 as amounts due from related parties.
 
  In 1996, the Company issued four warrants to Mr. Rizzone to purchase Class A
Common Stock. Two warrants were issued in consideration of the payment of $300
in connection with Mr. Rizzone's 1996 Employment Agreement. The first warrant
granted him the right to purchase 15,000 shares of Class A Common Stock, at an
exercise price of $7.125 per share, exercisable on the date the first half of
the outstanding shares of Class E Common Stock were converted into shares of
Class B Common Stock (an event which occurred prior to the end of 1996). The
other warrant granted him the right to purchase 15,000 shares of Class A
Common Stock, at an exercise price of $7.125 per share, exercisable on the
date all remaining outstanding shares of Class E Common Stock are converted
into shares of Class B Common Stock (an event which has yet to occur). Both
warrants terminate on January 1, 1999. Two additional warrants were issued in
lieu of interest owed by the Company to Mr. Rizzone for two short-term loans
totaling $200,000 made by him to fund operations. One warrant granted him the
right to purchase 11,765 shares of Class A Common Stock at an exercise price
of $8.50 per share (a $2.00 discount from the closing price of a share of
Class A Common Stock on the date the first loan was made). The other warrant
granted him the right to purchase 11,110 shares of Class A Common Stock at an
exercise price of $9.00 per share (a $2.00 discount from the closing price of
a share of Class A Common Stock on the date the second loan was made). Both
warrants were immediately exercisable and terminate on October 14, 2001.
 
  On January 10, 1996, the Company completed the sale of 512,996 shares and
341,997 shares (or 854,993 shares in the aggregate) of its Class A Common
Stock to Seiji Uehara, a director of the Company, and Isao Okawa,
respectively, for cash consideration of $5.848 per share (or $5,000,000 in the
aggregate). The per share purchase price, although less than the market price
of the Class A Common Stock at the time, was deemed to be fair to the Company
because the shares issued in the transaction were "restricted securities"
within the meaning of Rule 144 of the Securities Act. The average of the bid
and ask prices of the Company's Class A Common Stock on January 10, 1996 was
$7.50 per share. Under the stock purchase agreement between the parties, the
Company granted Messrs. Uehara and Okawa certain "piggy back" registration
rights and agreed to provide them certain indemnification. At the time of the
transaction, Mr. Uehara was also the president of NextCom, and Mr. Okawa was
the chairman and president of the parent of NextCom.
 
  In June 1996, NextCom advanced the Company $500,000 in cash. In lieu of
interest expense, NextCom received an additional 5% discount on all its
purchases of Company products until the advance was paid off in October 1996.
The amount of the additional discount received by NextCom totaled $23,312.
Total 1996 sales to NextCom were $1.5 million (or 6% of total revenues). At
December 31, 1996, the amount due the Company for product purchases by NextCom
was $899,381 (or 10% of the Company's total accounts receivable). The Company
also entered into a sales incentive plan with NextCom to promote sales growth
and market awareness of the Company's products. In connection with the plan,
the Company paid NextCom $27,000 in cash.

                          LOAN AND SECURITY AGREEMENT


BORROWER:  NETVANTAGE, INC.

ADDRESS:   201 CONTINENTAL BOULEVARD, SUITE 201
           EL SEGUNDO, CALIFORNIA  90245

DATE:      JULY 15, 1996
                --

THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between
SILICON VALLEY BANK ("Silicon"), whose address is 3003 Tasman Drive, Santa
Clara, California 95054 and the borrower named above (the "Borrower"), whose
chief executive office is located at the above address ("Borrower's Address").

1.  LOANS.

  1.1  LOANS.  Silicon, in its reasonable discretion, will make loans to the
Borrower (the "Loans") in amounts determined by Silicon in its reasonable
discretion up to the amount (the "Credit Limit") shown on the Schedule to this
Agreement (the "Schedule"), provided no Event of Default and no event which,
with notice or passage of time or both, would constitute an Event of Default has
occurred.  The Borrower is responsible for monitoring the total amount of Loans
and other Obligations outstanding from time to time, and Borrower shall not
permit the same, at any time, to exceed the Credit Limit.  If at any time the
total of all outstanding Loans and all other Obligations exceeds the Credit
Limit, the Borrower shall immediately pay the amount of the excess to Silicon,
without notice or demand.

  1.2  INTEREST.  All Loans and all other monetary Obligations shall bear
interest at the rate shown on the Schedule hereto.  Interest shall be payable
monthly, on the due date shown on the monthly billing from Silicon to the
Borrower. Silicon may, in its discretion, charge interest to Borrower's deposit
accounts maintained with Silicon.

  1.3  FEES.  The Borrower shall pay to Silicon a loan origination fee in the
amount shown on the Schedule hereto concurrently herewith.  This fee is in
addition to all interest and other sums payable to Silicon and is not
refundable.

  1.4  LETTERS OF CREDIT.  Silicon, in its reasonable discretion, will, from
time to time during the term of this Agreement, on the request of the Borrower,
issue letters of credit for the account of the Borrower ("Letters of Credit"),
in an aggregate amount at any one time outstanding not to exceed the Letter of
Credit Sublimit shown on the Schedule, provided that, on the date the Letters of
Credit are to be issued, Borrower has available to it Loans in an amount equal
to or greater than the face amount of the Letters of Credit to be issued.
Letters of Credit shall be in form and substance acceptable to Silicon in its
sole discretion, shall be payable in United States dollars and shall have an
expiry date no later than the Maturity Date *.  Prior to the issuance of any
Letters of Credit, Borrower shall execute and deliver to Silicon applications
for letters of credit, and letter of credit agreements on Silicon's standard
forms, and such other documentation as Silicon shall specify (the "Letter of
Credit Documentation"). Fees for Letters of Credit shall be as provided in the
Letter of Credit Documentation. Borrower shall indemnify, defend and hold
Silicon harmless from any loss, cost, expense or liability, including without
limitation reasonable attorneys fees, arising out of or relating to Letters of
Credit. The Credit Limit and the Loans available to Borrower under this
Agreement shall be reduced by the face amount of Letters of Credit from time to
time outstanding.

  * PROVIDED THAT LETTERS OF CREDIT MAY HAVE A MATURITY DATE UP TO TWELVE MONTHS
BEYOND THE MATURITY DATE IN EFFECT FROM TIME TO TIME, PROVIDED THAT IF ON THE
MATURITY DATE, OR ON ANY EARLIER EFFECTIVE DATE OF TERMINATION, THERE ARE ANY
OUTSTANDING LETTERS OF CREDIT ISSUED BY SILICON OR ISSUED BY ANOTHER INSTITUTION
BASED UPON AN APPLICATION, GUARANTEE, INDEMNITY OR SIMILAR AGREEMENT ON THE PART
OF SILICON, THEN ON SUCH DATE BORROWER SHALL PROVIDE TO SILICON CASH COLLATERAL
IN AN AMOUNT EQUAL TO THE FACE AMOUNT OF ALL SUCH LETTERS OF CREDIT PLUS ALL
INTEREST, FEES AND COST DUE OR TO BECOME DUE IN CONNECTION THEREWITH, TO SECURE

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

2.  GRANT OF SECURITY INTEREST.

  2.1  OBLIGATIONS.  The term "Obligations" as used in this Agreement means the
following:  the obligation to pay all Loans and all interest thereon when due,
and to pay and perform when due all other present and future indebtedness,
liabilities, obligations, guarantees, covenants, agreements, warranties and
representations of the Borrower to Silicon, whether joint or several, monetary
or non-monetary, and whether created pursuant to this Agreement or any other
present or future agreement or otherwise.  Silicon may, in its discretion,
require that Borrower pay monetary Obligations in cash to Silicon, or charge
them to Borrower's Loan account, in which event they will bear interest at the
same rate applicable to the Loans.  Silicon may also, in its discretion, charge
any monetary Obligations to Borrower's deposit accounts maintained with Silicon.
Silicon will notify the Borrower of any such charges to Borrower's deposit
accounts.  Such charges shall not be deemed to be a setoff for any purpose.

  2.2  COLLATERAL.  As security for all Obligations, the Borrower hereby grants
Silicon a continuing security interest in all of the Borrower's interest in the
types of property described below, whether now owned or hereafter acquired, and
wherever located (collectively, the "Collateral"):  (a) All accounts, contract
rights, chattel paper, letters of credit, documents, securities, money, and
instruments, and all other obligations now or in the future owing to the
Borrower; (b) All inventory, goods, merchandise, materials, raw materials, work
in process, finished goods, farm products, advertising, packaging and shipping
materials, supplies, and all other tangible personal property which is held for
sale or lease or furnished under contracts of service or consumed in the
Borrower's business, and all warehouse receipts and other documents; and (c) All
equipment, including without limitation all machinery, fixtures, trade fixtures,
vehicles, furnishings, furniture, materials, tools, machine tools, office
equipment, computers and peripheral devices, appliances, apparatus, parts, dies,
and jigs; (d) All general intangibles including, but not limited to, deposit
accounts, goodwill, names, trade names, trademarks and the goodwill of the
business symbolized thereby, trade secrets, drawings, blueprints, customer
lists, patents, patent applications, copyrights, security deposits, loan
commitment fees, federal, state and local tax refunds and claims, all rights in
all litigation presently or hereafter pending for any cause or claim (whether in
contract, tort or otherwise), and all judgments now or hereafter arising
therefrom, all claims of Borrower against Silicon, all rights to purchase or
sell real or personal property, all rights as a licensor or licensee of any
kind, all royalties, licenses, processes, telephone numbers, proprietary
information, purchase orders, and all insurance policies and claims (including
without limitation credit, liability, property and other insurance), and all
other rights, privileges and franchises of every kind; (e) All books and
records, whether stored on computers or otherwise maintained; and (f) All
substitutions, additions and accessions to any of the foregoing, and all
products, proceeds and insurance proceeds of the foregoing, and all guaranties
of and security for the foregoing; and all books and records relating to any of
the foregoing.  Silicon's security interest in any present or future technology
(including patents, trade secrets, and other technology) shall be subject to any
licenses or rights now or in the future granted by the Borrower to any third
parties in the ordinary course of Borrower's business; provided that if the
Borrower proposes to sell, license or grant any other rights with respect to any
technology in a transaction that, in substance, conveys a major part of the
economic value of that technology, Silicon shall first be requested to release
its security interest in the same, and Silicon may withhold such release in its
discretion *.

  * PROVIDED THAT IT IS UNDERSTOOD THAT SILICON WILL NOT WITHHOLD ITS CONSENT TO
    --------                                                                    
A TRANSACTION THAT PERMITS A THIRD PARTY TO COMPLETE MANUFACTURING OF A PRODUCT
INVOLVING SUCH TECHNOLOGY ONLY, WITHOUT THE GRANT OF ANY OTHER RIGHTS TO SUCH
PARTY IN SUCH TECHNOLOGY ARISING IN CONNECTION THEREWITH

3.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

  The Borrower represents and warrants to Silicon as follows, and the Borrower
covenants that the following representations will continue to be true, and that
the Borrower will comply with all of the following covenants:

  3.1  CORPORATE EXISTENCE AND AUTHORITY.  The Borrower, if a corporation, is
and will continue to be, duly authorized, validly existing and in good standing
under the laws of the jurisdiction of its incorporation.  The Borrower is and
will continue to be qualified and licensed to do business in all jurisdictions
in which any failure to do so would have a material adverse effect on the
Borrower.  The execution, delivery and performance by the Borrower of this
Agreement, and all other documents contemplated hereby have been duly and
validly authorized, are enforceable against the Borrower in accordance with
their terms, and do not violate any law or any provision of, and are not grounds
for acceleration under, any agreement or instrument which is binding upon the
Borrower.  Borrower has no subsidiaries except as set forth on the Schedule.

  3.2  NAME; TRADE NAMES AND STYLES.  The name of the Borrower set forth in the
heading to this Agreement is its correct name.  Listed on the Schedule hereto
are all prior names of the Borrower and all of Borrower's present and prior
trade names.  The Borrower shall give Silicon 15 days' prior written notice
before changing its name or doing business under any other name.  The Borrower
has complied, and will in the future comply, with all laws relating to the
conduct of business under a fictitious business name.

  3.3  PLACE OF BUSINESS; LOCATION OF COLLATERAL.  The address set forth in the
heading to this Agreement is the Borrower's chief executive office.  In
addition, the Borrower has places of business and Collateral is located only at
the locations set forth on the Schedule to this Agreement.  The Borrower will
give Silicon at least 15 days prior written notice before changing its chief
executive office or locating the Collateral at any other location.

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

  3.4  TITLE TO COLLATERAL; PERMITTED LIENS.  The Borrower is now, and will at
all times in the future be, the sole owner of all the Collateral, except for
items of equipment which are leased by the Borrower *.  The Collateral now is
and will remain free and clear of any and all liens, charges, security
interests, encumbrances and adverse claims, except for the following ("Permitted
Liens"):  (i) purchase money security interests in specific items of equipment;
(ii) leases of specific items of equipment; (iii) liens for taxes not yet
payable; (iv) additional security interests and liens consented to in writing by
Silicon in its reasonable discretion, which consent shall not be unreasonably
withheld; and (v) security interests being terminated substantially concurrently
with this Agreement.  Silicon will have the right to require, as a condition to
its consent under subparagraph (iv) above, that the holder of the additional
security interest or lien sign an intercreditor agreement on Silicon's then
standard form, acknowledge that the security interest is subordinate to the
security interest in favor of Silicon, and agree not to take any action to
enforce its subordinate security interest so long as any Obligations remain
outstanding, and that the Borrower agree that any uncured default in any
obligation secured by the subordinate security interest shall also constitute an
Event of Default under this Agreement.  Silicon now has, and will continue to
have, a perfected and enforceable security interest in all of the Collateral,
subject only to the Permitted Liens, and the Borrower will at all times defend
Silicon and the Collateral against all claims of others.  None of the Collateral
now is or will be affixed to any real property in such a manner, or with such
intent, as to become a fixture.

 * AND SUBJECT TO THE PROVISIONS SET FORTH IN THE LAST SENTENCE OF SECTION 2.2

prior to the Maturity Date as follows:  (i) by the Borrower, effective three
business days after written notice of termination is given to Silicon; or (ii)
by Silicon at any time after the occurrence of an Event of Default, without
notice, effective immediately.

  5.3  PAYMENT OF OBLIGATIONS.  On the Maturity Date or on any earlier effective
date of termination, the Borrower shall pay and perform in full all Obligations,
whether evidenced by installment notes or otherwise, and whether or not all or
any part of such Obligations are otherwise then due and payable. Without
limiting the generality of the foregoing, if on the Maturity Date, or on any
earlier effective date of termination, there are any outstanding letters of
credit issued by Silicon or issued by another institution based upon an

Agreement, all of Silicon's security interests in all of the Collateral and all
of the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the reasonable
discretion of Silicon, Silicon may, in its sole discretion, refuse to make any
further Loans after termination. No termination shall in any way affect or
impair any right or remedy of Silicon, nor shall any such termination relieve
the Borrower of any Obligation to Silicon, until all of the Obligations have
been paid and performed in full. Upon payment and performance in full of all the
Obligations, Silicon shall promptly deliver to the Borrower termination
statements, requests for reconveyances and such other documents as may be
required to fully terminate any of Silicon's security interests.

limits his subordination agreement; or (l) there shall be a change in [the
record or beneficial ownership of an aggregate of more than 20% of the

  6.2  REMEDIES.  Upon the occurrence of any Event of Default, and at any time

(all of which are hereby expressly waived by the Borrower), may do any one or

credit or other credit facilities to or for the benefit of the Borrower under
this Agreement or any other document or agreement; (b) Accelerate and declare
all or any part of the Obligations to be immediately due, payable, and

Borrower hereby authorizes Silicon without judicial process to enter onto any of

cause a custodian to remain on the premises in exclusive control thereof without
charge for so long as Silicon deems it reasonably necessary in order to complete
the enforcement of its rights under this Agreement or any other agreement;
provided, however, that should Silicon seek to take possession of any or all of
the Collateral by Court process, the Borrower hereby irrevocably waives:  (i)
any bond and any surety or security relating thereto required by any statute,
court rule or otherwise as an incident to such possession; (ii) any demand for

all checks and other payments received with respect to all accounts and general
intangibles, together with any necessary indorsements, within one day after the
date received by the Borrower; (f) Complete the processing, manufacturing or

and for the purpose of removal, Silicon shall have the right to use the
Borrower's premises, vehicles, hoists, lifts, cranes, equipment and all other

Collateral in its condition at the time Silicon obtains possession of it or

and/or private sales, in lots or in bulk, for cash, exchange or other property,
or on credit, and to adjourn any such sale from time to time without notice
other than oral announcement at the time scheduled for sale. Silicon shall have
the right to conduct such disposition on the Borrower's premises without charge,
for such time or times as Silicon deems reasonable, or on Silicon's premises, or
elsewhere and the Collateral need not be located at the place of disposition.
Silicon may directly or through any affiliated company purchase or lease any
Collateral at any such public disposition, and if permissible under applicable
law, at any private

disposition. Any sale or other disposition of Collateral shall not relieve the
Borrower of any liability the Borrower may have if any Collateral is defective
as to title or physical condition or otherwise at the time of sale; (h) Demand
payment of, and collect any accounts and general intangibles comprising
Collateral and, in connection therewith, the Borrower irrevocably authorizes

general, special or other deposit accounts with Silicon; and (j) Demand and

obligations incurred by Silicon with respect to the foregoing shall be added to
and become part of the Obligations, shall be due on demand, and shall bear
interest at a rate equal to the highest interest rate applicable to any of the
Obligations. Without limiting any of Silicon's rights and remedies, from and
after the occurrence of any Event of Default, the interest rate applicable to
the Obligations shall be increased by an additional five percent per annum.

  6.3  STANDARDS FOR DETERMINING COMMERCIAL REASONABLENESS.  The Borrower and
Silicon agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable:  (i) Notice of the sale is given to the
Borrower at least seven days prior to the sale, and, in the case of a public
sale, notice of the sale is published at least seven days before the sale in a
newspaper of general circulation in the county where the sale is to be
conducted; (ii) Notice of the sale describes the collateral in general, non-
specific terms; (iii) The sale is conducted at a place designated by Silicon,
with or without the Collateral being present; (iv) The sale commences at any
time between 8:00 a.m. and 6:00 p.m; (v) Payment of the purchase price in cash
or by cashier's check or wire transfer is required; (vi) With respect to any
sale of any of the Collateral, Silicon may (but is not obligated to) direct any
prospective purchaser to ascertain directly from the Borrower any and all
information concerning the same.  Silicon may employ other methods of noticing
and selling the Collateral, in its discretion, if they are commercially
reasonable.

  6.4  POWER OF ATTORNEY.  Upon the occurrence of any Event of Default, without
limiting Silicon's other rights and remedies, the Borrower grants to Silicon an
irrevocable power of attorney coupled with an interest, authorizing and
permitting Silicon (acting through any of its employees, attorneys or agents) at
any time, at its option, but without obligation, with or without notice to the
Borrower, and at the Borrower's expense, to do any or all of the following, in
the Borrower's name or otherwise: (a) Execute on behalf of the Borrower any
documents that Silicon may, in its sole and absolute discretion, deem advisable
in order to perfect and maintain Silicon's security interest in the Collateral,
or in order to exercise a right of the Borrower or Silicon, or in order to fully
consummate all the transactions contemplated under this Agreement, and all other
present and future agreements; (b) Execute on behalf of the Borrower any
document exercising, transferring or assigning any option to purchase, sell or
otherwise dispose of or to lease (as lessor or lessee) any real or personal
property which is part of Silicon's Collateral or in which Silicon has an
interest; (c) Execute on behalf of the Borrower, any invoices relating to any
account, any draft against any account debtor and any notice to any account
debtor, any proof of claim in bankruptcy, any Notice of Lien, claim of
mechanic's, materialman's or other lien, or assignment or satisfaction of
mechanic's, materialman's or other lien; (d) Take control in any manner of any
cash or non-cash items of payment or proceeds of Collateral; endorse the name of
the Borrower upon any instruments, or documents, evidence of payment or
Collateral that may come into Silicon's possession; (e) Endorse all checks and
other forms of remittances received by Silicon; (f) Pay, contest or settle any
lien, charge, encumbrance, security interest and adverse claim in or to any of
the Collateral, or any judgment based thereon, or otherwise take any action to
terminate or discharge the same; (g) Grant extensions of time to pay, compromise
claims and settle accounts and general intangibles for less than face value and
execute all releases and other documents in connection therewith; (h) Pay any
sums required on account of the Borrower's taxes or to secure the release of any
liens therefor, or both; (i) Settle and adjust, and give releases of, any
insurance claim that relates to any of the Collateral and obtain payment
therefor; (j) Instruct any third party having custody or control of any books or
records belonging to, or relating to, the Borrower to give Silicon the same
rights of access and other rights with respect thereto as Silicon has under this
Agreement; and (k) Take any action or pay any sum required of the Borrower
pursuant to this Agreement and any other present or future agreements. Silicon
shall exercise the foregoing powers in a commercially reasonable manner. Any and
all reasonable sums paid and any and all reasonable costs, expenses,
liabilities, obligations and attorneys' fees incurred by Silicon with respect to
the foregoing shall be added to and become part of the Obligations, shall be
payable on demand, and shall bear interest at a rate equal to the highest
interest rate applicable to any of the Obligations. In no event shall Silicon's
rights under the foregoing power of attorney or any of Silicon's other rights
under this Agreement be deemed to indicate that Silicon is in control of the
business, management or properties of the Borrower.

  6.5  APPLICATION OF PROCEEDS.  All proceeds realized as the result of any sale
of the Collateral shall be applied by Silicon first to the costs, expenses,
liabilities, obligations and attorneys' fees incurred by Silicon in the exercise
of its rights under this Agreement, second to the interest due upon any of the
Obligations, and third to the principal of 

                                      -7-

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

the Obligations, in such order as Silicon shall determine in its sole
discretion. Any surplus shall be paid to the Borrower or other persons legally
entitled thereto; the Borrower shall remain liable to Silicon for any
deficiency. If, Silicon, in its sole discretion, directly or indirectly enters
into a deferred payment or other credit transaction with any purchaser at any
sale or other disposition of Collateral, Silicon shall have the option,
exercisable at any time, in its sole discretion, of either reducing the
Obligations by the principal amount of purchase price or deferring the reduction
of the Obligations until the actual receipt by Silicon of the cash therefor.

  6.6  REMEDIES CUMULATIVE.  In addition to the rights and remedies set forth in
this Agreement, Silicon shall have all the other rights and remedies accorded a
secured party under the California Uniform Commercial Code and under all other
applicable laws, and under any other instrument or agreement now or in the
future entered into between Silicon and the Borrower, and all of such rights and
remedies are cumulative and none is exclusive.  Exercise or partial exercise by
Silicon of one or more of its rights or remedies shall not be deemed an
election, nor bar Silicon from subsequent exercise or partial exercise of any
other rights or remedies.  The failure or delay of Silicon to exercise any
rights or remedies shall not operate as a waiver thereof, but all rights and
remedies shall continue in full force and effect until all of the Obligations
have been fully paid and performed.

7.  GENERAL PROVISIONS.

  7.1  CREDITING PAYMENTS.  Payments shall not be applied to the Obligations
until received by Silicon in immediately available federal funds, and any wire
transfer or other payment so received after 12:00 noon Pacific time shall be
deemed to have been received by Silicon as of the opening of business on the
next business day.

  7.2  NOTICES.  All notices to be given under this Agreement shall be in
writing and shall be given either personally or by regular first-class mail, or
certified mail return receipt requested, addressed to Silicon or the Borrower at
the addresses shown in the heading to this Agreement, or at any other address
designated in writing by one party to the other party.  All notices shall be
deemed to have been given upon delivery in the case of notices personally
delivered to the Borrower or to Silicon, or at the expiration of two business
days following the deposit thereof in the United States mail, with postage
prepaid.

  7.3  SEVERABILITY.  Should any provision of this Agreement be held by any
court of competent jurisdiction to be void or unenforceable, such defect shall
not affect the remainder of this Agreement, which shall continue in full force
and effect.

  7.4  INTEGRATION.  This Agreement and such other written agreements, documents
and instruments as may be executed in connection herewith are the final, entire
and complete agreement between the Borrower and Silicon and supersede all prior
and contemporaneous negotiations and oral representations and agreements, all of
which are merged and integrated in this Agreement.  There are no oral
                                                    -----------------
understandings, representations or agreements between the parties which are not
- -------------------------------------------------------------------------------
set forth in this Agreement or in other written agreements signed by the parties
- --------------------------------------------------------------------------------
in connection herewith.
- -----------------------

  7.5  WAIVERS.  The failure of Silicon at any time or times to require the
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between the Borrower and Silicon shall not
waive or diminish any right of Silicon later to demand and receive strict
compliance therewith.  Any waiver of any default shall not waive or affect any
other default, whether prior or subsequent thereto.  None of the provisions of
this Agreement or any other agreement now or in the future executed by the
Borrower and delivered to Silicon shall be deemed to have been waived by any act
or knowledge of Silicon or its agents or employees, but only by a specific
written waiver signed by an officer of Silicon and delivered to the Borrower.
The Borrower waives demand, protest, notice of protest and notice of default or
dishonor, notice of payment and nonpayment, release, compromise, settlement,
extension or renewal of any commercial paper, instrument, account, general
intangible, document or guaranty at any time held by Silicon on which the
Borrower is or may in any way be liable, and notice of any action taken by
Silicon, unless expressly required by this Agreement.

  7.6  NO LIABILITY FOR ORDINARY NEGLIGENCE.  Neither Silicon, nor any of its
directors, officers, employees, agents, attorneys or any other person affiliated
with or representing Silicon shall be liable for any claims, demands, losses or
damages, of any kind whatsoever, made, claimed, incurred or suffered by the
Borrower or any other party through the ordinary negligence of Silicon, or any
of its directors, officers, employees, agents, attorneys or any other person
affiliated with or representing Silicon.

  7.7  AMENDMENT.  The terms and provisions of this Agreement may not be waived
or amended, except in a writing executed by the Borrower and a duly authorized
officer of Silicon.

  7.8  TIME OF ESSENCE.  Time is of the essence in the performance by the
Borrower of each and every obligation under this Agreement.

  7.9  ATTORNEYS FEES AND COSTS.  The Borrower shall reimburse Silicon for all
reasonable attorneys' fees and all filing, recording, search, title insurance,
appraisal, audit, and other reasonable costs incurred by Silicon, pursuant to,
or in connection with, or relating to this Agreement (whether or not a lawsuit
is filed), including, but not limited to, any reasonable attorneys' fees and
costs Silicon incurs in order to do the following:  prepare and negotiate this
Agreement and the documents relating to this Agreement; obtain legal advice in
connection with this Agreement; enforce, or seek to enforce, any of its rights;
prosecute actions against, or defend actions by, account debtors; commence,
intervene in, or defend any action or proceeding; initiate any complaint to be

claim, third-party claim, or other claim; examine, audit, copy, and inspect any
of the Collateral or any of the Borrower's books and records; protect, obtain
possession of, lease, dispose of, or otherwise enforce Silicon's security
interest in, the Collateral; and otherwise represent Silicon in any litigation
relating to the Borrower. In satisfying Borrower's obligation hereunder to

reimburse Silicon for attorneys fees, Borrower may, for convenience, issue

checks directly to Silicon's attorneys, Levy, Small & Lallas, but Borrower
- --------------------------------------------------------------------------
acknowledges and agrees that Levy, Small & Lallas is representing only Silicon
- ------------------------------------------------------------------------------
and not Borrower in connection with this Agreement. If either Silicon or the
- ---------------------------------------------------
Borrower files any lawsuit against the other predicated on a breach of this
Agreement, the prevailing party in such action shall be entitled to recover its
reasonable costs and attorneys' fees, including (but not limited to) reasonable
attorneys' fees and costs incurred in the enforcement of, execution upon or
defense of any order, decree, award or judgment. All attorneys' fees and costs
to which Silicon may be entitled pursuant to this Paragraph shall immediately
become part of the Borrower's Obligations, shall be due on demand, and shall
bear interest at a rate equal to the highest interest rate applicable to any of
the Obligations.

  7.10  BENEFIT OF AGREEMENT.  The provisions of this Agreement shall be binding
upon and inure to the benefit of the respective successors, assigns, heirs,
beneficiaries and representatives of the parties hereto; provided, however, that
the Borrower may not assign or transfer any of its rights under this Agreement
without the prior written consent of Silicon, and any prohibited assignment
shall be void.  No consent by Silicon to any assignment shall release the
Borrower from its liability for the Obligations.

  7.11  JOINT AND SEVERAL LIABILITY.  If the Borrower consists of more than one
person, their liability shall be joint and several, and the compromise of any
claim with, or the release of, any Borrower shall not constitute a compromise
with, or a release of, any other Borrower.

  7.12  PARAGRAPH HEADINGS; CONSTRUCTION.  Paragraph headings are only used in
this Agreement for convenience.  The Borrower acknowledges that the headings may
not describe completely the subject matter of the applicable paragraph, and the
headings shall not be used in any manner to construe, limit, define or interpret
any term or provision of this Agreement.  This Agreement has been fully reviewed
and negotiated between the parties and no uncertainty or ambiguity in any term
or provision of this Agreement shall be construed strictly against Silicon or
the Borrower under any rule of construction or otherwise.

  7.13  GOVERNING LAW; JURISDICTION; VENUE.  This Agreement and all acts and
transactions hereunder and all rights and obligations of Silicon and the
Borrower shall be governed by, and in accordance with, the laws of the State of
California.  Any undefined term used in this Agreement that is defined in the
California Uniform Commercial Code shall have the meaning assigned to that term
in the California Uniform Commercial Code.  As a material part of the
consideration to Silicon to enter into this Agreement, the Borrower (i) agrees
that all actions and proceedings relating directly or indirectly hereto shall,
at Silicon's option, be litigated in courts located within California, and that
the exclusive venue therefor shall be Orange County; (ii) consents to the
jurisdiction and venue of any such court and consents to service of process in
any such action or proceeding by personal delivery or any other method permitted
by law; and (iii) waives any and all rights the Borrower may have to object to
the jurisdiction of any such court, or to transfer or change the venue of any
such action or proceeding.

  7.14  MUTUAL WAIVER OF JURY TRIAL.  THE BORROWER AND SILICON EACH HEREBY WAIVE
THE RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING BASED UPON, ARISING OUT
OF, OR IN ANY WAY RELATING TO, THIS AGREEMENT OR ANY OTHER PRESENT OR FUTURE
INSTRUMENT OR AGREEMENT BETWEEN SILICON AND THE BORROWER, OR ANY CONDUCT, ACTS
OR OMISSIONS OF SILICON OR THE BORROWER OR ANY OF THEIR DIRECTORS, OFFICERS,
EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSONS AFFILIATED WITH SILICON OR THE
BORROWER.  THIS WAIVER OF THE RIGHT TO JURY TRIAL APPLIES TO ALL CONTRACT
CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, COMMON LAW CLAIMS, STATUTORY CLAIMS
AND ALL OTHER CLAIMS AND CAUSES OF ACTION OF EVERY KIND.  EACH PARTY RECOGNIZES
AND AGREES THAT THE FOREGOING JURY TRIAL WAIVER CONSTITUTES A MATERIAL
INDUCEMENT TO THE OTHER PARTY TO ENTER INTO THIS AGREEMENT.  EACH PARTY
REPRESENTS AND WARRANTS THAT IT HAS REVIEWED THIS JURY TRIAL WAIVER WITH ITS
LEGAL COUNSEL AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS
FOLLOWING ITS CONSULTATION WITH ITS LEGAL COUNSEL.

                          LOAN AND SECURITY AGREEMENT

BORROWER:  NETVANTAGE, INC.

ADDRESS:   201 CONTINENTAL BOULEVARD, SUITE 201
           EL SEGUNDO, CALIFORNIA  90245

DATE:      AUGUST 16, 1996

     THIS SCHEDULE is an integral part of the Loan and Security Agreement
between Silicon Valley Bank ("Silicon") and the above-named borrower
("Borrower") of even date.

CREDIT LIMIT
(Section 1.1):      An amount not to exceed the lesser of:  (i) $5,000,000 at
                    any one time outstanding; or (ii) 70% of the Net Amount of
                    Borrower's accounts, which Silicon in its discretion deems
                    eligible for borrowing.  "Net Amount" of an account means
                    the gross amount of the account, minus all applicable sales,
                    use, excise and other similar taxes and minus all discounts,
                    credits and allowances of any nature granted or claimed.
                    Loans that are made based on Borrower's eligible accounts as
                    described herein are referred to as the "Accounts Loans."

                    Without limiting the fact that the determination of which
                    accounts are eligible for borrowing is a matter of Silicon's
                    discretion, the following will not be deemed eligible for
                    borrowing:  (a) accounts outstanding for more than 90 days
                    from the invoice date*; (b) accounts subject to any
                    contingencies, or arising from a consignment, guaranteed
                    sale, bill and hold, sale on approval or other transaction
                    in which payment by the account debtor is conditional; (c)
                    accounts owing from the United States or any department,
                    agency or instrumentality of the United States or any state,
                    city or municipality; (d) accounts owing from an account
                    debtor whose chief executive office or principal place of
                    business is outside the United States (unless the account is
                    pre-approved by Silicon in its discretion, or backed by a
                    letter of credit satisfactory to Silicon, or FCIA insured
                    satisfactory to Silicon, or the account arises from goods
                    shipped or services rendered to a branch or office of the
                    account debtor in the United States)**; (e) accounts owing
                    from one account debtor to the extent they exceed 25% of the
                    total eligible accounts outstanding***; (f) accounts owing
                    from an affiliate of Borrower****; and (g) accounts owing
                    from an account debtor to whom Borrower is or may be liable
                    for goods purchased from, or services received from, such
                    account debtor or otherwise (to the extent of the amount
                    owing to such account debtor).  In addition, if more than
                    50% of the accounts owing from an account debtor are
                    outstanding more than 90 days***** from the invoice date or
                    are otherwise not eligible for borrowing, then all accounts
                    owing from that account debtor will be deemed ineligible for
                    borrowing.

TERM LOANS          Borrower shall also have the option to convert up to
                    $1,000,000, in the aggregate, of Accounts Loans to term
                    loans (individually a "Term Loan" and collectively referred
                    to as the "Term Loans") during the period starting on the
                    original date of the Loan Agreement and ending on the date
                    twelve months thereafter, subject, however, to the

                    Borrower's satisfaction of all of the Conversion
                    Requirements (as defined below) in a manner satisfactory to
                    Silicon in its discretion (the date of the making of each
                    Term Loan is referred to as the "Term Loan Date").
                    Conversion of an Accounts Loan to a Term Loan as set forth
                    herein reinstates availability under the Credit Limit
                    regarding Accounts Loans up to the initial principal amount
                    of such Term Loan, provided that Accounts Loans in such an
                                       --------                               
                    amount are otherwise available to the Borrower pursuant to
                    the terms hereof.  The minimum amount of a Term Loan shall
                    be $250,000.  This option to convert Accounts Loans to Term
                    Loans is not a revolving facility and therefore repayment of
                    principal amounts of the Term Loans does not create
                    additional availability for the making of new Term Loans.

                    The principal balance of each Term Loan shall be repaid by
                    the Borrower to Silicon in 36 equal monthly principal
                    payments, commencing one month after the Term Loan Date and
                    continuing thereafter for 35 months, on which final payment
                    date the entire unpaid balance of such Term Loan and all
                    other Obligations relating thereto shall be due and payable.
                    In addition to making such indicated principal payments,
                    Borrower shall pay to Silicon interest on the principal
                    amount of the Term Loans outstanding from time to time in
                    accordance with Section 1.2 of the Loan Agreement.

                    The term "Conversion Requirements" means all of the
                    following:

                    (a)  Borrower's providing written notice to Silicon stating
                    its desire to convert a stated amount of its Accounts Loans
                    to a Term Loan, subject to the terms and provisions of this
                    Agreement;

                    (b)  Borrower's providing written and other evidence
                    satisfactory to Silicon in its discretion that the requested
                    amount of the Term Loan is equal to or less than the sum of
                    (i) 80% of the sum of the invoice amounts of new items of
                    equipment that the Borrower purchases after the date of this
                    Agreement, satisfactory to Silicon in its discretion; (ii)
                    25% of the sum of the invoice amounts of software items that
                    the Borrower purchases after the date of this Agreement,
                    satisfactory to Silicon in its discretion; plus (iii) 25% of
                                                               ----             
                    the aggregate amount of expenditures Borrower makes after

                    two fiscal quarters) or the Liquidity Coverage Ratio
                    (relating to the Borrower's most recent month end period),

                    Silicon determines are necessary or desirable in its
                    discretion; and

                    (g)  No Event of Default is then occurring or would

                    and after such time after the date hereof that Borrower
                    incurs no losses (after taxes) in two consecutive fiscal
                    quarters, the rate shall be equal to "Prime Rate" in effect
                    from time to time, plus 1.50% per annum.

                    Interest shall be calculated on the basis of a 360-day year
                    for the actual number of days elapsed.  "Prime Rate" means
                    the rate announced from time to time by Silicon as its
                    "prime rate;" it is a base rate upon which other rates
                    charged by Silicon are based, and it is not necessarily the
                    best rate available at Silicon.  The interest rate
                    applicable to the Obligations shall change on each date
                    there is a change in the Prime Rate.

  DEFERRED 
  REVENUES:         For purposes of the above quick asset ratio, deferred
                    revenues shall not be counted as current liabilities. For

  DEBT:             "Liabilities" for purposes of the foregoing covenants do not
                    include indebtedness which is subordinated to the

                    form specified by Silicon or by language in the instrument
                    evidencing the indebtedness which is acceptable to Silicon.

OTHER COVENANTS
(Section 4.1):      Borrower shall at all times comply with all of the following

                    specified from time to time by Silicon, copies of Borrower's
                    sales and collection journals, and such other information,
                    in such detail and with such frequency as Silicon shall from

                    of all of Borrower's accounts, of every kind, in whatever
                    form received, shall be held by the Borrower in trust for
                    Silicon and shall be either (i) delivered by the Borrower to
                    Silicon in kind, in the same form as received, with any
                    necessary endorsements, within one business day after
                    receipt, or (ii) within one business day after receipt,
                    deposited to a bank account previously identified to
                    Silicon, which has been established pursuant to a written
                    agreement with Silicon which provides that all funds in such
                    account will be transferred to Silicon on a daily basis, and
                    in that event the Borrower shall deliver copies of all
                    checks and other proceeds so deposited and a copy of the
                    deposit receipt to Silicon within one business day after
                    such deposit. Borrower shall have no right to, and agrees
                    not to, commingle any of the proceeds of the accounts with
                    the Borrower's own funds, and the Borrower agrees not to
                    use, divert or withhold any such proceeds. The Borrower
                    will, upon request by Silicon and in such form and at such
                    times as Silicon shall request, give notice to the account
                    debtors on the accounts of the assignment of, and the grant
                    of a security interest in, the accounts to Silicon and
                    Silicon may itself give such notice at any time, without
                    notice to the Borrower, requiring such account debtors to
                    pay the accounts directly to Silicon, and in any such event,
                    the Borrower's privilege of collecting the accounts shall
                    automatically be deemed revoked.

                    6.  COLLATERAL CONTROL MONTHLY FEE. In addition to all other
                    amounts payable by Borrower hereunder, Borrower shall pay to
                    Silicon a Collateral Control Fee in the amount of $1,000 per
                    month.

          "Exchange Act" shall mean the Securities Exchange Act of 1934, as

          "Holder" shall mean (i) any Purchaser to the extent such Purchaser

          "Permitted Transferees" shall mean any party to whom Each Purchaser

                                      -2-
<PAGE>
 
     1.2  Right to Registration. If at any time or from time to time, the
          ---------------------                                          
Company shall determine to register any Common for its own account or for the
account of others, other than a registration relating solely to employee benefit
plans or a registration relating solely to a Commission Rule 145 transaction or
a registration on any registration form which does not include substantially the
same information as would be required to be included in a registration statement
covering the sale of Registrable Securities, the Company will:

          (a)  promptly give to all Holders and Founding Shareholders written
notice thereof (which shall include a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under the applicable blue
sky or other state securities laws); and

          (b)  include in such registration (and any related qualification under
blue sky laws or other compliance), and in any underwriting involved therein,
all of the Registrable Securities specified in a written request by a Holder and
all shares of Common specified in a written request or requests by Founding
Shareholders, provided such written requests are received by the Company within
twenty (20) days following receipt by such Holders and Founding Shareholders of
such notice from the Company.

     1.3  Underwriting. If the registration of which the Company gives notice is
          ------------                                                          
for a registered public offering involving an underwriting, the Company shall so
advise the Holders and Founding Shareholders in the written notice given
pursuant to paragraph 1.2(a). In such event, the right of any Holder and
Founding Shareholder to registration pursuant to Section 1.2 shall be
conditioned upon such party's participation in such underwriting and the
inclusion of such party's Registrable Securities and such Founding Shareholder's
Common in the underwriting to the extent provided herein.  All parties proposing
to distribute their securities through such underwriting shall (together with
the Company and the other holders distributing their securities through such
underwriting) enter into an underwriting agreement in the customary form with
the underwriter or underwriters selected for such underwriting by the Company.
Notwithstanding any other provision of Section 1.2, if the Company and the
underwriter or underwriters determine that marketing factors require a
limitation of the number of shares to be underwritten, the underwriter may
exclude from such underwriting all or some of the shares proposed for
registration on behalf of Holders, Founding Shareholders, and other holders of
Company securities, on the following basis:

          (a) shares held by any person who does not have contractual rights to
cause the Company to register such shares shall first be excluded;

          (b) if further reductions are required, the shares that Founding
Shareholders have requested to be registered will next be excluded, such
reductions to be allocated as nearly as practicable based on the pro rata share
of the number of shares requested by all Founding Shareholder to be registered;
and

                                      -3-
<PAGE>
 
          (c) if further reductions are required, Registrable Securities will
next be excluded, such reductions to be allocated as nearly as practicable among
Holders in proportion to the number of shares that such Holder requests to be
registered hereunder bears to the total number of shares that all Holders
request to be registered, unless all such Holders shall otherwise unanimously
agree and advise the Company in writing.

          No shares excluded from the underwriting by reason of the
underwriter's marketing limitation shall be included in such registration. If
any Holder or Founding Shareholder disapproves of the terms of any such
underwriting, such person may elect to withdraw therefrom by written notice to
the Company and the underwriter. The Registrable Securities and/or other
securities so withdrawn from such underwriting shall also be withdrawn from such
registration; provided, however, that, if by the withdrawal of such shares a
greater number of Registrable Securities held by other Holders may be included
in such registration (up to the maximum of any limitation imposed by the
underwriters), then the Company shall offer to all Holders who have included
Registrable Securities in the registration the right to include additional
Registrable Securities in the same proportion used above in determining the
underwriter limitation.

     1.4  Preparation and Filing. In the case of each registration,
          ----------------------                                   
qualification, or compliance effected by the Company pursuant to this Exhibit B,
the Company will keep each Holder advised in writing as to the initiation of
each registration, qualification, and compliance and as to the completion
thereof. At its expense the Company will:

          (a) Keep such registration, qualification, or compliance effective for
a period of one hundred twenty (120) days or until the Holder or Holders have
completed the distribution described in the registration statement relating
thereto, whichever first occurs.

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

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

          (d) Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which 

                                      -4-
<PAGE>
 
the prospectus included in such registration statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in light of the circumstances then existing.

          (e) Furnish, at the request of any Holder requesting registration of
Registrable Securities pursuant to this Exhibit B, on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with said registration, if such securities are being sold through underwriters,
or the date that the registration statement with respect to such securities
becomes effective, (i) an opinion, dated as of such date, of the counsel
representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public
offering, addressed to the underwriters, if any, and to the Holders requesting
registration of Registrable Securities and (ii) a letter dated as of such date,
from the independent accountants of the Company, in form and substance as is
customarily given by independent accountants to underwriters in an underwritten
public offering, addressed to the underwriters, if any, and to the Holders
requesting registration of Registrable Securities.

     1.5   Expenses of Registration. All Registration Expenses incurred in
           ------------------------                                       
connection with any registration under this Exhibit B shall be borne by the
Company; and all Selling Expenses shall be borne by the holders of the
securities so registered pro rata on the basis of the number of shares so
registered.

     1.6  Indemnification.
          --------------- 

          (a) The Company shall indemnify each Holder (which term, for purposes
of this Section 1.6, shall be deemed to include Founding Shareholders who
include shares in a registration) participating in any registration,
qualification, or compliance effected pursuant to this Exhibit B with respect to
Registrable Securities held by such Holder, each of its officers, directors,
partners, controlling persons and legal counsel, and each underwriter, if any,
and each person who controls any underwriter, against all claims, losses,
damages, and liabilities (or actions in respect thereof), including any of the
foregoing incurred in settlement of any litigation, commenced or threatened, to
which they may become subject under the Securities Act, the Exchange Act, or
other federal or state law, arising out of or based on (i) any untrue statement
(or alleged untrue statement) of a material fact contained in any prospectus,
offering circular or other similar document incident to any such registration,
qualification or compliance, or based on 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 in light of the circumstances under which
they were made, or (ii) any violation by the Company of any federal, state, or
common law rule or regulation applicable to the Company in connection with any
such registration, qualification or compliance, and will reimburse each such
Holder, each of its officers, directors, partners, controlling persons and legal
counsel, each such underwriter, and each person who controls any 

                                      -5-
<PAGE>
 
such underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating and/or defending any such claim, loss, damage,
liability, or action, as incurred, provided that the Company will not be liable
in any case to the extent that any such claim, loss, damage, liability or
expense arises out of or is based on any untrue statement or omission, made in
reliance on and in conformity with written information furnished to the Company
by a Holder or underwriter specifically for use therein.

          (b) Each Holder will, if Registrable Securities held by such Holder
are included in the securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, each of its officers,
directors, partners, controlling persons and legal counsel, each underwriter, if
any, of the Company's securities covered by such registration statement, each
person who controls such underwriter, and each other Holder, each of its
officers, directors, controlling person and partners, against all claims,
losses, damages and liabilities (or actions in respect thereof) arising out of
or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any such registration statement, prospectus, offering
circular, or other similar document, or 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 in light of the circumstances under which
they were made, and will reimburse the Company, such other Holders, such
directors, officers, persons, underwriters, controlling persons or legal counsel
for any legal or any other expenses reasonably incurred in connection with
investigating and/or defending any such claim, loss, damage, liability, or
action, as incurred, in each case to the extent, but only to the extent, that
such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such registration statement, prospectus, offering circular,
or other document in reliance upon and in conformity with written information
furnished to the Company by such Holder specifically for use therein.
Notwithstanding anything herein to the contrary, the total amount for which any
Holder shall be liable under this subsection 1.6(b) shall not exceed the
aggregate proceeds received by such Holder from the sale of Registrable
Securities held by such Holder in such registration.

          (c) Each party entitled to indemnification under this Section 1.6 (the
"Indemnified Party") shall give notice to the party required to provide such
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has received written notice of any claim as to which indemnity may be sought,
and shall permit the Indemnifying Party to assume the defense of any such claim
or any litigation resulting therefrom, provided that counsel for the
Indemnifying Party who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld). The Indemnified Party may participate in such defense
at its own expense. The failure of any Indemnified Party to give notice as
provided herein shall relieve the Indemnifying Party of its obligations under
this Section 1.6 only to the extent that such failure to give notice shall
materially adversely prejudice the Indemnifying Party in the defense of any such

                                      -6-
<PAGE>
 
claim or any such litigation. No Indemnifying Party, in the defense of any such
claim or litigation, shall, except with the consent of each Indemnified Party,
consent to entry of any judgment or enter into any settlement that does not
include as an unconditional term thereof the giving by the claimant or plaintiff
to such Indemnified Party of a release from all liability in respect to such
claim or litigation.

                           WARRANT TO PURCHASE STOCK

WARRANT TO PURCHASE 30,000            ISSUE DATE:  JULY 15, 1996
SHARES OF THE CLASS A COMMON          EXPIRATION DATE:  JULY 15, 2001
STOCK OF NETVANTAGE, INC.             INITIAL EXERCISE PRICE:  $9.875 PER SHARE
 

THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for other
good and valuable consideration, SILICON VALLEY BANK ("Holder") is entitled to
purchase the number of fully paid and non-assessable shares of the class of
securities (the "Shares") of the corporation (the "Company") at the initial
exercise price per Share (the "Warrant Price") all as set forth above and as
adjusted pursuant to Article 2 of this Warrant, subject to the provisions and
upon the terms and conditions set forth in this Warrant.

ARTICLE 1.  EXERCISE.

          1.1      METHOD OF EXERCISE.  Holder may exercise this Warrant by
delivering a duly executed Notice of Exercise in substantially the form attached
as Appendix 1 to the principal office of the Company.  Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

          1.2      CONVERSION RIGHT.  In lieu of exercising this Warrant as
specified in Section 1.1, Holder may from time to time convert this Warrant, in
whole or in part, into a number of Shares determined by dividing (a) the
aggregate fair market value of the Shares or other securities otherwise issuable
upon exercise of this Warrant minus the aggregate Warrant Price of such Shares
by (b) the fair market value of one Share.  The fair market value of the Shares
shall be determined pursuant Section 1.4.

          1.3      [ALTERNATIVE STOCK APPRECIATION RIGHT.  At Holder's option,
the Company shall pay Holder the fair market value of the Shares issuable upon
conversion of this Warrant pursuant to Section 1.2 in cash in lieu of such
Shares.]

          1.4      FAIR MARKET VALUE.  If the Shares are traded in a public
market, the fair market value of the Shares shall be * [the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the business day immediately before Holder delivers
its Notice of Exercise to the Company.] If the Shares are not ** traded in a
public market, the Board of Directors of the Company shall determine fair market
value in its reasonable good faith judgment. The foregoing notwithstanding, if
Holder advises the Board of Directors in writing that Holder disagrees with such
determination, then the Company and Holder shall promptly agree upon a reputable
investment banking firm to undertake such valuation. If the valuation of such
investment banking firm is greater than that determined by the Board of
Directors, then all fees and expenses of such investment banking firm shall be
paid by the Company. In all other circumstances, such fees and expenses shall be
paid by Holder.

          * THE AVERAGE OF THE CLOSING PRICE OF SUCH STOCK ON THE NASDAQ
NATIONAL MARKET SYSTEM OR SMALL CAP ISSUE MARKET, AS APPLICABLE, FOR THE TEN
TRADING DAYS IMMEDIATELY PRECEDING THE DATE OF RECEIPT BY THE COMPANY OF THE
NOTICE OF EXERCISE

          ** NO LONGER

          1.5      DELIVERY OF CERTIFICATE AND NEW WARRANT.  Promptly after
Holder exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

          1.6      REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

          1.7 REPURCHASE ON SALE, MERGER OR CONSOLIDATION OF THE COMPANY.

          1.7.1.   "ACQUISITION".  For the purpose of this Warrant,
"Acquisition" means any sale, license, or other disposition of all or
substantially all of the assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

          1.7.2.   ASSUMPTION OF WARRANT.  If upon the closing of any
Acquisition the successor entity assumes the

securities, cash, and property as would be payable for the Shares issuable upon
exercise of the unexercised portion of this Warrant as if such Shares were
outstanding on the record date for the Acquisition and subsequent closing. The
Warrant Price shall be adjusted accordingly.

          1.7.3.   NONASSUMPTION.  If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and Holder has
not otherwise exercised this Warrant in full, then the unexercised portion of
this Warrant shall be deemed to have been automatically converted pursuant to
Section 1.2 and thereafter Holder shall participate in the acquisition on the
same terms as other holders of the same class of securities of the Company.

          1.7.4.   [PURCHASE RIGHT.  Notwithstanding the foregoing, at the
election of Holder, the Company shall purchase the unexercised portion of this
Warrant for cash upon the closing of any Acquisition for an amount equal to (a)
the fair market value of any consideration that would have been received by
Holder in consideration of the Shares had Holder exercised the unexercised
portion of this Warrant immediately before the record date for determining the
shareholders entitled to participate in the proceeds of the Acquisition, less
(b) the aggregate Warrant Price of the Shares, but in no event less than zero.]

ARTICLE 2.  ADJUSTMENTS TO THE SHARES.

          2.1      STOCK DIVIDENDS, SPLITS, ETC.  If the Company declares or
pays a dividend on its common stock (or the Shares if the Shares are securities
other than common stock) payable in common stock, or other securities,
subdivides the outstanding common stock into a greater amount of common stock,
or, if the Shares are securities other than common stock, subdivides the Shares
in a transaction that increases the amount of common stock into which the Shares
are convertible, then upon exercise of this Warrant, for each Share acquired,
Holder shall receive, without cost to Holder, the total number and kind of
securities to which Holder would have been entitled had Holder owned the Shares
of record as of the date the dividend or subdivision occurred.

          2.2      RECLASSIFICATION, EXCHANGE OR SUBSTITUTION.  Upon any
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this Warrant, Holder shall be entitled to receive, upon exercise
or conversion of this Warrant, the number and kind of securities and property
that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event.  Such an event shall include any automatic conversion of the
outstanding or issuable securities of the Company of the same class or series as
the Shares to common stock pursuant to the terms of the Company's Articles of
Incorporation upon the closing of a registered public offering of the Company's
common stock.  The Company or its successor shall promptly issue to Holder a new
Warrant for such new securities or other property.  The new Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 2 including, without
limitation, adjustments to the Warrant Price and to the number of securities or
property issuable upon exercise of the new Warrant.  The provisions of this
Section 2.2 shall similarly apply to successive reclassifications, exchanges,
substitutions, or other events.

          2.3      ADJUSTMENTS FOR COMBINATIONS, ETC.  If the outstanding Shares
are combined or consolidated, by reclassification or otherwise, into a lesser
number of shares, the Warrant Price shall be proportionately increased.

          2.4      ADJUSTMENTS FOR ADDITIONAL ISSUANCES.  The number of Shares
issuable upon exercise of this Warrant shall be subject to adjustment, from time
to time, as set forth in this Section 2.4.  The term "Silicon Percentage
Interest" shall mean the ratio of the number of shares subject of this Warrant
as of the date hereof to the number of fully diluted shares of the Company as in
effect as of the date hereof.  At such time, and from time to time, that the
number of fully diluted shares of the Company increases, the number of shares
subject of this Warrant shall be considered increased by such an amount in order
to maintain in effect the Silicon Percentage Interest at all times with respect
to the number of shares subject of this Warrant as a ratio to the then increased
number of fully diluted shares, provided in no instance shall the number of
                                --------                                   
shares subject of this Warrant be reduced.

          As used herein the number of fully diluted shares means the aggregate
amount of all common stock (including reissued shares) issued (or deemed to be
issued as noted in the following sentences).  The shares of common stock
ultimately issuable upon exercise of an option (including the shares of common
stock ultimately issuable upon conversion or exercise of a convertible security
issuable pursuant to an option) are deemed to be issued when the option is
Issued.  The shares of common stock ultimately issuable upon conversion or
exercise of a convertible security (other than a convertible security issued
pursuant to an option) shall be deemed Issued upon issuance of the convertible
security.

          2.5      NO IMPAIRMENT.  The Company shall not, by amendment of its
Articles of Incorporation or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue, or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed under this Warrant by the Company, but
shall at all times in good faith assist in carrying out of all the provisions of
this Article 2 and in taking all such action as may be necessary or appropriate
to protect Holder's rights under this Article against impairment.  If the
Company takes any action affecting the Shares or its common stock other than as
described above that adversely affects Holder's rights under this Warrant, the
Warrant Price shall be adjusted downward and the number of Shares issuable 

                                      -2-

Silicon Valley Bank                                    Warrant to Purchase Stock
- --------------------------------------------------------------------------------

upon exercise of this Warrant shall be adjusted upward in such a manner that the
aggregate Warrant Price of this Warrant is unchanged.

          2.6      FRACTIONAL SHARES.  No fractional Shares shall be issuable
upon exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share.  If a fractional share
interest arises upon any exercise or conversion of the Warrant, the Company
shall eliminate such fractional share interest by paying Holder amount computed
by multiplying the fractional interest by the fair market value of a full Share.

          2.7      CERTIFICATE AS TO ADJUSTMENTS.  Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish Holder with a certificate of its Chief Financial Officer
setting forth such adjustment and the facts upon which such adjustment is based.
The Company shall, upon written request, furnish Holder a certificate setting
forth the Warrant Price in effect upon the date thereof and the series of
adjustments leading to such Warrant Price.

                           WARRANT TO PURCHASE STOCK


WARRANT TO PURCHASE 30,000            ISSUE DATE:  AUGUST 16, 1996
SHARES OF THE CLASS A COMMON          EXPIRATION DATE:  AUGUST 16, 2001
STOCK OF NETVANTAGE, INC.             INITIAL EXERCISE PRICE:  $11.44 PER SHARE
 

THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for other
good and valuable consideration, SILICON VALLEY BANK ("Holder") is entitled to
purchase the number of fully paid and non-assessable shares of the class of
securities (the "Shares") of the corporation (the "Company") at the initial
exercise price per Share (the "Warrant Price") all as set forth above and as
adjusted pursuant to Article 2 of this Warrant, subject to the provisions and
upon the terms and conditions set forth in this Warrant.

ARTICLE 1.  EXERCISE.

          1.1      METHOD OF EXERCISE.  Holder may exercise this Warrant by
delivering a duly executed Notice of Exercise in substantially the form attached
as Appendix 1 to the principal office of the Company.  Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

          1.2      CONVERSION RIGHT.  In lieu of exercising this Warrant as
specified in Section 1.1, Holder may from time to time convert this Warrant, in
whole or in part, into a number of Shares determined by dividing (a) the
aggregate fair market value of the Shares or other securities otherwise issuable
upon exercise of this Warrant minus the aggregate Warrant Price of such Shares
by (b) the fair market value of one Share.  The fair market value of the Shares
shall be determined pursuant Section 1.4.

          1.3      [ALTERNATIVE STOCK APPRECIATION RIGHT.  At Holder's option,
the Company shall pay Holder the fair market value of the Shares issuable upon
conversion of this Warrant pursuant to Section 1.2 in cash in lieu of such
Shares.]

          1.4      FAIR MARKET VALUE.  If the Shares are traded in a public
market, the fair market value of the Shares shall be * [the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the business day immediately before Holder delivers
its Notice of Exercise to the Company.] If the Shares are [not] ** traded in a
public market, the Board of Directors of the Company shall determine fair market
value in its reasonable good faith judgment. The foregoing notwithstanding, if
Holder advises the Board of Directors in writing that Holder disagrees with such
determination, then the Company and Holder shall promptly agree upon a reputable
investment banking firm to undertake such valuation. If the valuation of such
investment banking firm is greater than that determined by the Board of
Directors, then all fees and expenses of such investment banking firm shall be
paid by the Company. In all other circumstances, such fees and expenses shall be
paid by Holder.

          * THE AVERAGE OF THE CLOSING PRICE OF SUCH STOCK ON THE NASDAQ
NATIONAL MARKET SYSTEM OR SMALL CAP ISSUE MARKET, AS APPLICABLE, FOR THE TEN
TRADING DAYS IMMEDIATELY PRECEDING THE DATE OF RECEIPT BY THE COMPANY OF THE
NOTICE OF EXERCISE

          ** NO LONGER

          1.5      DELIVERY OF CERTIFICATE AND NEW WARRANT.  Promptly after
Holder exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

          1.6      REPLACEMENT OF WARRANTS.  On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

          1.7 REPURCHASE ON SALE, MERGER OR CONSOLIDATION OF THE COMPANY.

          1.7.1.   "ACQUISITION".  For the purpose of this Warrant,
"Acquisition" means any sale, license, or other disposition of all or
substantially all of the assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

          1.7.2.   ASSUMPTION OF WARRANT.  If upon the closing of any
Acquisition the successor entity assumes the 


NOTE TO EDGAR VERSION:  Deleted language is indicated by brackets, not 
                        strike-throughs.

Silicon Valley Bank                                    Warrant to Purchase Stock

obligations of this Warrant, then this Warrant shall be exercisable for the same
securities, cash, and property as would be payable for the Shares issuable upon
exercise of the unexercised portion of this Warrant as if such Shares were
outstanding on the record date for the Acquisition and subsequent closing. The
Warrant Price shall be adjusted accordingly.

          1.7.3.   NONASSUMPTION.  If upon the closing of any Acquisition the
successor entity does not assume the obligations of this Warrant and Holder has
not otherwise exercised this Warrant in full, then the unexercised portion of
this Warrant shall be deemed to have been automatically converted pursuant to
Section 1.2 and thereafter Holder shall participate in the acquisition on the
same terms as other holders of the same class of securities of the Company.

          1.7.4.   [PURCHASE RIGHT.  Notwithstanding the foregoing, at the
election of Holder, the Company shall purchase the unexercised portion of this
Warrant for cash upon the closing of any Acquisition for an amount equal to (a)
the fair market value of any consideration that would have been received by
Holder in consideration of the Shares had Holder exercised the unexercised
portion of this Warrant immediately before the record date for determining the
shareholders entitled to participate in the proceeds of the Acquisition, less
(b) the aggregate Warrant Price of the Shares, but in no event less than zero.]

ARTICLE 2.  ADJUSTMENTS TO THE SHARES.

          2.1      STOCK DIVIDENDS, SPLITS, ETC.  If the Company declares or
pays a dividend on its common stock (or the Shares if the Shares are securities
other than common stock) payable in common stock, or other securities,
subdivides the outstanding common stock into a greater amount of common stock,
or, if the Shares are securities other than common stock, subdivides the Shares
in a transaction that increases the amount of common stock into which the Shares
are convertible, then upon exercise of this Warrant, for each Share acquired,
Holder shall receive, without cost to Holder, the total number and kind of
securities to which Holder would have been entitled had Holder owned the Shares
of record as of the date the dividend or subdivision occurred.

          2.2      RECLASSIFICATION, EXCHANGE OR SUBSTITUTION.  Upon any
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this Warrant, Holder shall be entitled to receive, upon exercise
or conversion of this Warrant, the number and kind of securities and property
that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event.  Such an event shall include any automatic conversion of the
outstanding or issuable securities of the Company of the same class or series as
the Shares to common stock pursuant to the terms of the Company's Articles of
Incorporation upon the closing of a registered public offering of the Company's
common stock.  The Company or its successor shall promptly issue to Holder a new
Warrant for such new securities or other property.  The new Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 2 including, without
limitation, adjustments to the Warrant Price and to the number of securities or
property issuable upon exercise of the new Warrant.  The provisions of this
Section 2.2 shall similarly apply to successive reclassifications, exchanges,
substitutions, or other events.

          2.3      ADJUSTMENTS FOR COMBINATIONS, ETC.  If the outstanding Shares
are combined or consolidated, by reclassification or otherwise, into a lesser
number of shares, the Warrant Price shall be proportionately increased.

          2.4      ADJUSTMENTS FOR ADDITIONAL ISSUANCES.  The number of Shares
issuable upon exercise of this Warrant shall be subject to adjustment, from time
to time, as set forth in this Section 2.4.  The term "Silicon Percentage
Interest" shall mean the ratio of the number of shares subject of this Warrant
as of the date hereof to the number of fully diluted shares of the Company as in
effect as of the date hereof.  At such time, and from time to time, that the
number of fully diluted shares of the Company increases, the number of shares
subject of this Warrant shall be considered increased by such an amount in order
to maintain in effect the Silicon Percentage Interest at all times with respect
to the number of shares subject of this Warrant as a ratio to the then increased
number of fully diluted shares, provided in no instance shall the number of
                                --------                                   
shares subject of this Warrant be reduced.

          As used herein the number of fully diluted shares means the aggregate
amount of all common stock (including reissued shares) issued (or deemed to be
issued as noted in the following sentences).  The shares of common stock
ultimately issuable upon exercise of an option (including the shares of common
stock ultimately issuable upon conversion or exercise of a convertible security
issuable pursuant to an option) are deemed to be issued when the option is
Issued.  The shares of common stock ultimately issuable upon conversion or
exercise of a convertible security (other than a convertible security issued
pursuant to an option) shall be deemed Issued upon issuance of the convertible
security.

          2.5      NO IMPAIRMENT.  The Company shall not, by amendment of its
Articles of Incorporation or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue, or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed under this Warrant by the Company, but
shall at all times in good faith assist in carrying out of all the provisions of
this Article 2 and in taking all such action as may be necessary or appropriate
to protect Holder's rights under this Article against impairment.  If the
Company takes any action affecting the Shares or its common stock other than as
described above that adversely affects Holder's rights under this Warrant, the
Warrant Price shall be adjusted downward and the number of Shares issuable

<PAGE>
 
Silicon Valley Bank                                    Warrant to Purchase Stock
- --------------------------------------------------------------------------------

upon exercise of this Warrant shall be adjusted upward in such a manner that the
aggregate Warrant Price of this Warrant is unchanged.

          2.6      FRACTIONAL SHARES.  No fractional Shares shall be issuable
upon exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the nearest whole Share.  If a fractional share
interest arises upon any exercise or conversion of the Warrant, the Company
shall eliminate such fractional share interest by paying Holder amount computed
by multiplying the fractional interest by the fair market value of a full Share.

          2.7      CERTIFICATE AS TO ADJUSTMENTS.  Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish Holder with a certificate of its Chief Financial Officer
setting forth such adjustment and the facts upon which such adjustment is based.
The Company shall, upon written request, furnish Holder a certificate setting
forth the Warrant Price in effect upon the date thereof and the series of
adjustments leading to such Warrant Price.

ARTICLE 3.  REPRESENTATIONS AND COVENANTS OF THE COMPANY.

          3.1      REPRESENTATIONS AND WARRANTIES.  The Company hereby
represents and warrants to the Holder as follows:

          (a) The initial Warrant Price referenced on the first page of this
Warrant is not greater than (i) the price per share at which the Shares were
last issued in an arms-length transaction in which at least $500,000 of the
Shares were sold and (ii) the fair market value of the Shares as of the date of
this Warrant.

          (b) All Shares which may be issued upon the exercise of the purchase

Lessee's payments under this paragraph during said Comparison Year were less 
than Lessee's Share as indicated on said statement, Lessee shall pay to Lessor 
the amount of the deficiency within ten (10) days after delivery by Lessor to 
Lessee of said statement. Lessor and Lessee shall forthwith adjust between them
by cash payment any balance determined to exist with respect to that portion of 
the last Comparison Year for which Lessee is responsible as to Operating Expense

end of such Comparison Year.

     4.3   Rent Increase.

           4.3.1 At the times set forth in paragraph 1.7 of the Basic Lease 
Provisions, the monthly Base Rent payable under paragraph 4.1 of this Lease 
shall be adjusted by the increase, if any, in the Consumer Price Index of the 
Bureau of Labor Statistics of the Department of Labor for All Urban Consumers, 
(1967=100), "All items," for the city nearest the location of the Building, 
herein referred to as "C.P.I.," since the date of this Lease.

           4.3.2 The monthly Base Rent payable pursuant to paragraph 4.3.1 
shall be calculated as follows: the Base Rent payable for the first month of the
term of this Lease, as set forth in paragraph 4.1 of this Lease, shall be 
multiplied by a fraction the numerator of which shall be the C.P.I. of the 
calendar month during which the adjustment is to take effect, and the 
denominator of which shall be the C.P.I. for the calendar month in which the 
original Lease term commences. The sum so calculated shall constitute the new 
monthly Base Rent hereunder, but, in no event, shall such new monthly Base Rent 
be less than the Base Rent payable for the month immediately preceding the date 
for the rent adjustment.

           4.3.3 In the event the compilation and/or publication of the C.P.I. 
shall be transferred to any other governmental department or bureau or

agency or shall be discontinued, then the index most nearly the same as the 
C.P.I. shall be used to make such calculations. In the event that Lessor and 
Lessee cannot agree on such alternative index, then the matter shall be 
submitted for decision to the American Arbitration Association in the County in 
which the premises are located, in accordance with the then rules of said 
association and the decision of the arbitrators shall be binding upon the 
parties, notwithstanding one party failing to appear after due notice of the 
proceeding. The cost of said Arbitrators shall be paid equally by Lessor and 
Lessee.

     4.3.4  Lessee shall continue to pay the rent at the rate previously in 
effect until the increase, if any, is determined. Within five (5) days following
the date on which the increase is determined, Lessee shall make such payment to 
Lessor as will bring the increased rental current, commencing with the effective
date of such increase through the date of any rental instalments then due. 
Thereafter the rental shall be paid at the increased rate.

     4.3.5  At such time as the amount of any change in rental required by this 
Lease is known or determined. Lessor and Lessee shall execute an amendment to 
this Lease setting forth such change.

5.  Security Deposit. Lessee shall deposit with Lessor upon execution hereof the
security deposit set forth in paragraph 1.9 of the Basic Lease Provisions as 
security for Lessee's faithful performance of Lessee's obligations hereunder. If
Lessee fails to pay rent or other charges due hereunder, or otherwise defaults 
with respect to any provision of this Lease, Lessor may use, apply or retain all
or any portion of said deposit for the payment of any rent or other charge in 
default for the payment of any other sum to which Lessor may become obligated by
reason of Lessee's default, or to compensate Lessor for any loss or damage which
Lessor may suffer thereby.  If Lessor so uses or applies all or any portion of 
said deposit, Lessee shall within ten (10) days after written demand therefor 
deposit cash with Lessor in an amount sufficient to restore said deposit to the 
full amount then required of Lessee. Lessor shall not be required to keep said 
security deposit separate from its general accounts if Lessee performs all of 
Lessee's obligations hereunder, said deposit, or so much thereof as has not 
heretofore been applied by Lessor, shall be returned, without payment of 
interest or other increment for its use, to Lessee (or, at Lessor's option, to 
the last assignee, if any, of Lessee's interest hereunder) within thirty (30) 
days following the expiration of the term hereof, and the date Lessee has 
vacated the premises. No trust relationship is created herein between Lessor and
Lessee with respect to said Security Deposit.

any manner to the Premises and the occupation and use by Lessee of the Premises.

violation.

expense or to terminate this Lease because of Lessor's failure to keep the
Premises in good order, condition and repair.

    7.2 Lessee's Obligations.

        (a) Notwithstanding lessor's obligation to keep the premises in good 
condition and repair, Lessee shall be responsible for payment of the cost 
thereof to Lessor as additional rent for that portion of the cost of any

Project, or any interest therein.

invitees. If necessary, all property insurance policies required under this 
Lease shall be endorsed to so provide.

agents, Lessor's master or ground lessor, partners and lenders, from and against
any and all claims for damage to the person or property of anyone or any entity

shall not be liable for injury to Lessee's business or any loss of income 
therefrom or for loss of or damage to the goods, wares, merchandise or other 
property of Lessee, Lessee's employees, invitees, customers, or any other person
in or about the Premises or the Office Building Project, nor shall Lessor be

Lessor shall not complete the restoration and repair within six (6) months after
such occurrence, Lessee may at Lessee's option cancel and terminate this Lease
by giving Lessor written notice of Lessee's election to do so at any time prior
to the commencement or completion, respectively, of such repair or restoration.
In such event this Lease shall terminate as of the date of such notice.

        (c) Lessee agrees to cooperate with Lessor in connection with any such
restoration and repair, including but not limited to the approval and/or
execution of plans and specifications required.

   9.6  Termination--Advance Payments. Upon termination of this Lease pursuant
to this paragraph 9, an equitable adjustment shall be made concerning advance
rent and any advance made by Lessee to Lessor. Lessor shall, in addition, return
to Lessee so much of Lessee's security deposit as has not theretofore been
applied by Lessor.

   9.7  Waiver. Lessor and Lessee waive the provisions of any statute which 
relates to termination of leases when leased property is destroyed and agree
that such event shall be governed by the terms of this Lease.

10. Real Property Taxes.

   10.1 Payment of Taxes. Lessor shall pay the real property tax, as defined in 
paragraph 10.3, applicable to the Office Building Project subject to 
reimbursement by Lessee of Lessee's Share of such taxes in accordance with 
provisions of paragraph 4.2, except as otherwise provided in paragraph 10.2.

   10.2 Additional Improvements. Lessee shall not be responsible for paying any 
increase in real property tax specified in the tax assessor's records and work 
sheets being caused by additional improvements placed upon the Office Building 
Project by other lessees or by Lessor for the exclusive enjoyment of any other 
lessee. Lessee shall, however, pay to Lessor at the time that Operating Expenses
are payable under paragraph 4.2(c) the entirety of any increase in real property
tax if assessed solely by reason of additional improvements placed upon the 
Premises by Lessee or at Lessee's request.

   10.3 Definition of "Real Property Tax." As used herein, the term "real
property tax" shall include any form of real estate tax or assessment, general,
special, ordinary or extraordinary, and any license fee, commercial rental tax,
improvement bond or bonds, levy or tax (other than inheritance, personal income
or estate taxes) imposed on the Office Building Project or any portion thereof
by any authority having the direct or indirect power to tax, including any city,
county, state or federal government, or any school, agricultural, sanitary,
fire, street, drainage or other improvement district thereof, as against any
legal or equitable interest of Lessor in the Office Building Project or in any
portion thereof, as against Lessor's right to rent or other income therefrom,
and as against Lessor's business of leasing the Office Building Project. The
term "real property tax" shall also include any tax, fee, levy, assessment or
charge (i) in substitution of, partially or totally, any tax, fee, levy,
assessment or charge hereinabove included within the definition of "real
property tax," or (ii) the nature of which was hereinbefore included within the
definition of "real property tax," or (iii) which is imposed for a service or
right not charged prior to June 1, 1978, or if previously charged, has been
increased since June 1, 1978, or (iv) which is imposed as a result of a change
in ownership, as defined by applicable local statutes for property tax purposes,
of the Office Building Project or which is added to a tax or charge hereinbefore
included within the definition of real property tax by reason of such change of
ownership, or (v) which is imposed by reason of this transaction, any
modifications or changes hereto, or any transfers hereof.

   10.4 Joint Assessment. If the improvements or property, the taxes for which 
are to be paid separately by Lessee under paragraph 10.2 or 10.5 are not 
separately assessed, Lessee's portion of that tax shall be equitably determined 
by Lessor from the respective valuations assigned in the assessor's work sheets 
or such other information (which may include the cost of construction) 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.

        (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

   11.1 Services Provided by Lessor. Lessor shall provide heating, ventilation,
air conditioning, elevator and janitorial service as reasonably required,
reasonable amounts of electricity for normal lighting and office machines, water
for reasonable and normal drinking and lavatory use, and replacement light bulbs
and/or fluorescent tubes and ballasts for standard overhead fixtures.

   11.2 Services Exclusive to Lessee. Lessee shall pay for all water, gas, heat,
light, power, telephone and other utilities and services specially or
exclusively supplied and/or metered exclusively to the Premises or to Lessee,
together with any taxes thereon. If any such services are not separately metered
to the Premises, Lessee shall pay at Lessor's option, either Lessee's Share or a
reasonable proportion to be determined by Lessor of all charges jointly metered
with other premises in the Building.

   11.3 Hours of Service. Said services and utilities shall be provided during 
generally accepted business days and hours or such other days or hours as may 
hereafter be set forth. Utilities and services required at other times shall be 
subject to advance request and reimbursement by Lessee to Lessor of the cost 
thereof.

<PAGE>
 
    11.4 Excess Usage by Lessee. Lessee shall not make connection to the 
utilities except by or through existing outlets and shall not install or use 
machinery or equipment in or about the Premises that uses excess water, lighting
or power, or suffer or permit any act that causes extra burden upon the 
utilities or services, including but not limited to security services, over 
standard office usage for the Office Building Project. Lessor shall require
Lessee to reimburse Lessor for any excess expenses or costs that may arise out 
of a breach of this subparagraph by Lessee. Lessor may, in its sole discretion, 
install at Lessee's expense supplement equipment and/or separate metering 
applicable to Lessee's excess usage or loading.

    11.5 Interruptions. There shall be no abatement of rent and Lessor shall 
not be liable in any respect whatsoever for the inadequacy, stoppage,
interruption or discontinuance of any utility or service due to riot, strike,
labor dispute, breakdown, accident, repair, or other cause beyond Lessor's
reasonable control or in cooperation with governmental request or directions.

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 unreasonably withhold or 
delay, 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 material 
default and breach of this Lease without the need for notice to Lessee under 
paragraph 13.1. "Transfer" within the meaning of this paragraph 12 shall include
the transfer or transfers aggregating: (a) if Lessee is a corporation, more than
twenty-five percent (25%) of the voting stock of such corporation, or (b) if 
Lessee is a partnership, more than twenty-five percent (25%) of the profit and 
loss participation in such partnership.

    12.2 Lessee Affiliate. Notwithstanding the provisions of paragraph 12.1 
hereof, Lessee may assign or sublet the Premises, or any portion thereof, 
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, (a) said assignee shall
assume, in full, the obligations of Lessee under this Lease under the terms of 
this Lease and (b) Lessor shall be given written notice of such assignment and
assumption. 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 Applicable to Assignment and Subletting.

         (a) Regardless of Lessor's consent, no assignment or subletting shall 
release Lessee of Lessee's obligations hereunder or alter the primary liability 
of Lessee to pay the rent and other sums due Lessor hereunder including Lessee's
Share of Operating Expense Increase, and to perform all other obligations to be 
performed by Lessee hereunder.

         (b) Lessor may accept rent from any person other than Lessee pending 
approval or disapproval of such assignment.

         (c) Neither a delay in the approval or disapproval of such assignment
or subletting, 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.

         (d) If Lessee's obligations under this Lease have been guaranteed by 
third parties, then an assignment or sublease, and Lessor's consent thereto, 
shall not be effective unless said guarantors give their written consent to such
to such sublease and terms thereof.

         (e) The consent by Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to
any subsequent or successive assignment or subletting by the sublessee. However,
Lessor may consent to subsequent subletting 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 under this Lease or said
sublease; however, such persons shall not be responsible to the extent any such
amendment or modification enlarges or increases the obligations of the Lessee or
sublessee under this Lease or such sublease.
 
         (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) Lessor's written consent to any assignment or subletting of the 
Premises by Lessee shall not constitute an acknowledgement 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.

         (h) The discovery of the fact that any financial statement relied upon 
by Lessor in giving its consent to and assignment or subletting was materially 
false shall, at Lessor's election, render Lessor's said consent null and void.

    12.4 Additional 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 deemed 
included in all subleases under this Lease whether or not expressly incorporated
therein:

         (a) 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 sublessee 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 sublease 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, which shall not be unreasonably withheld or
delayed.

         (b) 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 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.

         (c) No sublessee shall further assign or sublet all or any part of the 
Premises without Lessor's prior written consent.

         (d) 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 three (3) 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 Lessor's Expenses. 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 cost and expenses incurred in 
connection therewith, including attorneys', architects', engineers' or other 
consultants fees.

    12.6 Conditions to Consent. Lessor reserves the right to condition any 
approval to assign or sublet upon Lessor's determination that (a) the proposed
assignee or sublessee shall conduct a business on the Premises of a quality
substantially equal to that of Lessee and consistent with the general character
of the other occupants of the Office Building Project and not in violation of
any exclusives or rights then held by other tenants, and (b) the proposed
assignee or subleasee be at least as financially responsible as Lessee was
expected to be at the time of the execution of this Lease or of such assignment
or subletting, whichever is greater, as is necessary to satisfy Lessor's then
current underwriting requirements for a subtenant or assignee or Lessor's
internal requirements.

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 vacation or abandonment of the Premises by Lessee. Vacation of 
the Premises shall include the failure to occupy the Premises for a continuous 
period of sixty (60) days or more, whether or not the rent is paid.

         (b) The breach by Lessee of any of the covenants, conditions or 
provisions of paragraphs 7.3(a), (b) or (d) (alterations), 12.1 (assignment or 
subletting), 13.1(a) (vacation or abandonment), 13.1(e) (insolvency), 13.1(f)
(false statement), 16(a) (estoppel certificate), 39(b) (subordination), 33
(auctions), or 41.1 (easements), all of which are hereby deemed to be material,
non-curable defaults without the necessity of any notice by Lessor to Lessee
thereof.

         (c) 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 statues such
Notice to Pay Rent or Quit shall also constitute the notice required by this
subparagraph.

<PAGE>
 
         (d) The failure by Lessee to observe or perform any of the covenants,
conditions or provisions of the Lease to be observed or performed by Lessee 
other than those referenced in subparagraphs (b) and (c), 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 if 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 Lessee 
commenced such cure within said thirty (30) day period and thereafter diligently
pursues 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.

         (e)(i) The making by Lessee of any general arrangement or general 
assignment for the benefit of creditors; (ii) Lessee becoming a "debtor" as 
defined in 11 U.S.C. (S)101 or any successor statute 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(e) is contrary to 
any applicable law, such provision shall be of no force or effect.

         (f) The discovery by Lessor that any financial statement given to 
Lessor by Lessee, or its successor in interest or by any guarantor of Lessee's 
obligation hereunder, was materially false.

   13.2  Remedies. In the event of any material default or breach of this 
Lease 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's 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.

   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 30-day period and thereafter diligently
pursues 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 Expense Increase 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 Office Building Project. Accordingly, if any 
installment of Base Rent, Operating Expense Increase, 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 other rights and remedies granted hereunder.

14. Condemnation. If the Premises or any portion thereof or the Office Building 
Project 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; provided that if so
much of the Premises or the Office Building Project are taken by such 
condemnation as would substantially and adversely affect the operation and 
profitability of Lessee's business conducted from the Premises, Lessee shall 
have the option, to be exercised only in writing within thirty (30) days after 
Lessor shall have given Lessee written notice of such taking (or in the absence 
of such notice, within thirty (30) days after the condemning authority shall 
have taken possession), to 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 and Lessee's 
Share of Operating Expense Increase shall be reduced in the proportion that the 
floor area of the Premises taken bears to the total floor area or the Premises. 
Common Areas taken shall be excluded from the Common Areas usable by Lessee and 
no reduction of rent shall occur with respect thereto or by reason thereof. 
Lessor shall have the option in its sole discretion to terminate this Lease as 
of the taking of possession by the condemning authority, by giving written 
notice to Lessee of such election within thirty (30) days after the receipt of 
notice of a taking by condemnation of any part of the Premises of the Office 
Building Project. Any award for the taking of all or any part of the Premises or
the Office Building Project 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 any separate award for loss of or 
damage to Lessee's trade fixtures, removable personal property and unamortized 
tenant improvements that have been paid for by Lessee. For that purpose the cost
of such improvements shall be amortized over the original term of this Lease 
excluding any options. 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 damages 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) The brokers involved in this transaction are THE SEELEY COMPANY and CB
                                                     -------------------------
COMMERCIAL INC. as "listing broker" and THE KAUFMAN GROUP as "cooperating 
- ---------------                         -----------------
broker," licensed real estate broker(s). A "cooperating broker" is defined as 
any broker other than the listing broker entitled to a share of any commission 
arising under this Lease. Upon execution of this Lease by both parties, Lessor 
shall pay to said brokers jointly, or in such separate shares as they may 
mutually designate in writing, 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 $ (per separate 
                                                        ----------------
agreement), for brokerage services rendered by said broker(s) to Lessor in this 
transaction.

    (b) Lessor further agrees that (i) 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 (ii) 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 (iii) if Lessee remains in possession of
the Premises after the expiration of the term of this Lease after having failed
to exercise an Option, or (iv) 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 any adjacent property in which Lessor has an interest, or (v) if the Base
Rent is increased, whether by agreement or operation of an escalation clause
contained herein, then as to any of said transactions or rent increases, 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. Said fee shall be paid at the
time such increased rental is determined.

    (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 interest 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. Each listing and cooperating broker
shall be a third party beneficiary of the provisions of this paragraph 15 to the
extent of their interest in any commission arising under this Lease and may 
enforce that right directly against Lessor; provided, however, that all brokers 
having a right to any part of such total commission shall be a necessary party 
to any suit with respect thereto.

    (d) Lessee and Lessor each represent and warrant to the other that neither 
has had any dealings with any person, firm, broker or finder (other than the 
person(s), if any, whose names are set forth in paragraph 15(a), above) in
connection with the negotiation of this Lease and/or the consummation of the
transaction contemplated hereby, and no other broker or other person, firm or
entity is entitled to any commission or finder's fee in connection with said
transaction and Lessee and Lessor do each hereby indemnify and hold the other
harmless from and against any costs, expenses, attorney's fees or liability for
compensation or charges which may be claimed by any such unnamed broker, finder
or other similar party by reason of any dealings or actions of the indemnifying
party.

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 that this 
Lease, as so modified, is in full force and effect) and the date

to which the rent and other charges are paid in advance, if any, and (ii) 
acknowledging that there are not, to the responding party's knowledge, any 
uncured defaults on the part of the requesting party, or specifying such 
defaults if any are claimed. Any such statement may be conclusively relied upon 
by any prospective purchaser or encumbrancer of the Office Building Project or 
of the business of Lessee.

   (b) At the requesting party's option, the failure to deliver such statement 
within such time shall be a material default of this Lease by the party who is 
to respond, without any further notice to such party, or it shall be 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 in 
advance. 

   (c) If Lessor desires to finance, refinance, or sell the Office Building 
Project, or 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 be used only for the purposes herein set forth.

17. Lessor's Liability. The term "Lessor" as used herein shall mean only the 
owner or owners, at the time in question, of the fee title or a lessee's 
interest in a ground lease of the Office Building Project, 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 by
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 or judgments 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.

20. Time of Essence. Time is of the essence with respect to the obligations to 
be performed under this Lease.

21. Additional Rent. All monetary obligations of Lessee to Lessor under the 
terms of this Lease, including but not limited to Lessee's Share of Operating 
Expense Increase and any other expenses payable by Lessee hereunder shall be 
deemed to be rent.

22. Incorporation of Prior Agreements; Amendments. This Lease contains all 
agreements of the parties with respect to any matter mentioned herein. No prior 
or contemporaneous agreement or understanding pertaining to any such matter 
shall be effective. This Lease may be modified in writing only, signed by the 
parties in interest at the time of the modification. Except as otherwise stated 
in this Lease, Lessee hereby acknowledges that neither the real estate broker 
listed in paragraph 15 hereof nor any cooperating broker on this transaction nor
the Lessor or any employee or agents of any of said persons has made any oral or
written warranties or representations to Lessee relative to the condition or use
by Lessee of the Premises or the Office Building Project and Lessee acknowledges
that Lessee assumes all responsibility regarding the Occupational Safety Health 
Act, the legal use and adaptability of the Premises and the compliance thereof 
with all applicable laws and regulations in effect during the term of this 
Lease.

23. Notices. Any notice required or permitted to be given hereunder shall be in 
writing and may be given by personal delivery or by certified or registered 
mail, and shall be deemed sufficiently given if delivered or addressed to Lessee
or to Lessor at the address noted below or adjacent to the signature of the 
respective parties, as the case may be. Mailed notices shall be deemed given 
upon actual receipt at the address required, or forty-eight hours following 
deposit in the mail, postage prepaid, whichever first occurs. Either party may 
by notice to the other specify a different address for notice purposes except 
that upon Lessee's taking possession of the Premises, the Premises shall 
constitute Lessee's address for notice purposes. A copy of all notices required
or permitted to be given to Lessor hereunder shall be concurrently transmitted
to such party or parties at such addresses as Lessor may from time to time
hereafter designate by notice to Lessee.

24. Waivers. No waiver by Lessor of any provision hereof shall be deemed a 
waiver of any other provision hereof or of any subsequent breach by Lessee of 
the same or any other provision. Lessor's consent to, or approval of, any act 
shall not be deemed to render unnecessary the obtaining of Lessor's consent to 
or approval of any subsequent act by Lessee. The acceptance of rent hereunder by
Lessor shall not be a waiver of any preceding breach by Lessee of any provision 
hereof, other than the failure of Lessee to pay the particular rent so accepted,
regardless of Lessor's knowledge of such preceding breach at the time of 
acceptance of such rent.

25. Recording. Either Lessor or Lessee shall, upon request of the other, 
execute, acknowledge and deliver to the other a "short form" memorandum of this 
Lease for recording purposes.

26. Holding Over. If Lessee, with Lessor's consent, remains in possession of the
Premises or any part thereof after the expiration of the term hereof, such 
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease pertaining to the obligations of Lessee, except that the rent payable 
shall be two hundred percent (200%) of the rent payable immediately preceding 
the termination date of this Lease, and all Options, if any, granted under the 
terms of this Lease shall be deemed terminated and be of no further effect 
during said month to month tenancy.

27. Cumulative Remedies. No remedy or election hereunder shall be deemed 
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28. Covenants and Conditions. Each provision of this Lease performable by Lessee
shall be deemed both a covenant and a condition.

29. Binding Effect; Choice of Law. Subject to any provisions hereof restricting 
assignment or subletting by Lessee and subject to the provisions of paragraph 
17, this Lease shall bind the parties, their personal representatives, 
successors and assigns. This Lease shall be governed by the laws of the State 
where the Office Building Project is located and any litigation concerning this 
Lease between the parties hereto shall be initiated in the county in which the 
Office Building Project is located.

30. Subordination.

   (a) This Lease, and any Option or right of first refusal granted hereby, at 
Lessor's option, shall be subordinate to any ground lease, mortgage, deed of 
trust, or any other hypothecation or security now or hereafter placed upon the 
Office Building Project 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. 

   (b) Lessee agrees to execute any documents required to effectuate 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 attorney-in-fact and
in Lessee's name, place and stead, to execute such documents in accordance with 
this paragraph 30(b).

31. Attorneys' Fees.

    31.1 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, trial or appeal thereon, shall be entitled to his reasonable
attorneys' fees to be paid by the losing party as fixed by the court in the same
or a separate suit, and whether or not such action is pursued in decision or
judgment. The provisions of this paragraph shall inure to the benefit of the
broker named herein who seeks to enforce a right hereunder.

    31.2 The attorneys' fee award shall not be computed in accordance with any 
court fee schedule, but shall be such as to fully reimburse all attorneys' fees 
reasonably incurred in good faith.

    31.3 Lessor shall be entitled to reasonable attorneys' fees and all other 
costs and expenses incurred in the preparation and service of notice of default 
and consultations in connection therewith, whether or not a legal transaction is
subsequently commenced in connection with such default. 

32. Lessor's Access.

    32.1 Lessor and Lessor's agents shall have the right to enter the Premises
at reasonable times for the purpose of inspecting the same, performing any
services required of Lessor, showing the same to prospective purchasers,
lenders, or lessees, taking such safety measures, erecting such scaffolding or
other necessary structures, making such alterations, repairs, improvements or
additions to the Premises or to the Office Building Project as Lessor may
reasonably deem necessary or desirable and the erecting, using and maintaining
of utilities, services, pipes and conduits through the Premises and/or other
premises as long as there is no material adverse effect to Lessee's use of the
Premises. 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.

    32.2 All activities of Lessor pursuant to this paragraph shall be without 
abatement of rent, nor shall Lessor have any liability to Lessee for the same.

    32.3 Lessor shall have the right to retain keys to the Premises and to
unlock all doors in or upon the Premises other than to files, vaults and safes,
and in the case of emergency to enter the Premises by any reasonably appropriate
means, and any such entry shall not be deemed a forceable or unlawful entry or
detainer of the Premises or an eviction. Lessee waives any charges for damages
or injuries or interference with Lessee's property or business in connection
therewith.

33.Auctions. Lessee shall not conduct, nor permit to be conducted, either 
voluntarily or involuntarily, any auction upon the Premises or the Common Areas 
without first having obtained Lessor's prior written consent. Notwithstanding 
anything to the contrary in this Lease, Lessor shall not be obligated to 
exercise any standard of reasonableness in determining whether to grant such 
consent. The holding of any auction on the Premises or Common Areas in violation
of this paragraph shall constitute a material default of this Lease.

34.Signs. Lessee shall not place any sign upon the Premises or the Office 
Building Project without Lessor's prior written consent. Under no circumstances 
shall Lessee place a sign on any roof of the Office Building Project.

35.Merger. The voluntary or other surrender of this Lease by Lessee, or a 
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 paragraphs 33 (auctions) and 34 (signs) 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.

37.Guarantor. In the event that there is a guarantor of this Lease, said 
guarantor shall have the same obligations as Lessee under this Lease.

38.Quiet Possession. Upon Lessee paying the rent for the Premises and observing
and performing all of the covenants, conditions and provisions on Lessee's part 
to be observed and performed hereunder, Lessee shall have quiet possession of 
the Premises for the entire term hereof subject to all of the 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 execution is binding upon
all parties holding an ownership interest in the Office Building Project.

39.Options

    39.1 Definition. As used in this paragraph the word "Option" has the 
following meaning: (1) the right or option to extend the term of this Lease or 
to renew this Lease or to extend or renew any lease that Lessee has on other 
property of Lessor; (2) the option of right of first refusal to lease the 
Premises or the right of first offer to lease the Premises or the right of first
refusal to lease other space within the Office Building Project or other 
property of Lessor or the right of first offer to lease other space within the 
Office Building Project or other property of Lessor; (3) the right or option to 
purchase the Premises or the Office Building Project, or the right of first 
refusal to purchase the Premises or the Office Building Project or the right of 
first offer to purchase the Premises or the Office Building Project, or the 
right or option to purchase other property of Lessor, or the right of first 
refusal to purchase other property of Lessor or the right of first offer to 
purchase other property of Lessor.

    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(c) or 13.1(d) and continuing until the noncompliance alleged in 
said notice of default is cured, or (ii) during the period of time commencing on
the day 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) in the event that Lessor has given to Lessee three 
or more notices of default under paragraph 13.1(c), or paragraph 13.1(d), 
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, (iv) if Lessee has committed any non-curable breach, including without 
limitation those described in paragraph 13.1(b), or is otherwise in default of 
any of the terms, covenants or conditions of this Lease.

         (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).

40.Security Measures--Lessor's Reservations.

    40.1 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 Office Building Project. 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 security protection for the Office Building Project 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).

    40.2 Lessor shall have the following rights:

or building in which the Premises are located upon not less than 90 days prior 
written notice;

graphics on the door of the Premises and such portions of the Common Areas as 
Lessor shall reasonably deem appropriate;

long as such exclusive does not conflict with any rights expressly given herein;

         (d) To place such signs, notices or displays as Lessor reasonably deems
necessary or advisable upon the roof, exterior of the buildings or the Office 
Building Project or on pole signs in the Common Areas;

    40.3 Lessee shall not:

         (a) Use a representation (photographic or otherwise) of the Building or
the Office Building Project or their name(s) in connection with Lessee's
business;

         (b) Suffer or permit anyone, except in emergency, to go upon the roof
of the Building.

    41.1 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.

    41.2 The obstruction of Lessee's view, air, or light by any structure 
erected in the vicinity of the Building, whether by Lessor or third parties, 
shall in no way affect this Lease or impose any liability upon Lessor.

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 make 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.

this Lease as may be reasonably required by an institutional lender in

13. Completion of Improvements

    Lessor shall construct and complete improvements to the Premises in 
accordance with the plans and specifications prepared by_______________________

_____________________________________________, dated__________________________,

consisting of sheets________________________.(the "Improvements")

14. Preparation of Plans and Specifications

    Within______days after the date of this Lease Lessor shall prepare at its 
cost and deliver to Lessee for its approval______copies of preliminary plans and
specifications for the completion of the Improvements, which plans and 
specifications shall itemize the work to be done by each party, including a cost
estimate of any work required of Lessor in excess of Lessor's Standard 
Improvements. Lessee shall approve said preliminary plans and specifications and
preliminary cost estimate or specify with particularity its objection thereto 
within______days following receipt thereof. Failure to so approve or disapprove 
within said period of time shall constitute approval thereof. If Lessee shall 
reject said preliminary plans and specifications either partially or totally, 
and they cannot in good faith be modified within ten (10) days after such 
rejection to be acceptable to Lessor and Lessee, this Lease shall terminate and
neither party shall thereafter be obligated to the other party for any reason
whatsoever having to do with this Lease, except that Lessee shall be refunded
any security deposit or prepaid rent. The plans and specifications, when
approved by Lessee, shall supersede any prior agreement concerning the
Improvements.

15. Construction
    
    If Lessor's cost of constructing the Improvements to the Premises exceeds 
the cost of Lessor's Standard Improvements, Lessee shall pay to Lessor in cash 
before the commencement of such construction a sum equal to such excess.

    If the final plans and specifications are approved by Lessor and Lessee, and
Lessee pays Lessor for such excess, then Lessor shall, at its sole cost and 
expense, construct the Improvements in accordance with said approved final plans
and specifications and all applicable rules, regulations, laws or ordinances.

16. Completion.

    16.1 Lessor shall obtain a building permit to construct the Improvements as 
soon as possible.

    16.2 Lessor shall complete the construction of the Improvements as soon as 
reasonably possible after the obtaining of necessary building permits.

    16.3 The term "Completion," as used in this Work Letter, is hereby defined
to mean the date the building department of the municipality having jurisdiction
of the Premises shall have made a final inspection of the Improvements and
authorized a final release of restrictions on the use of public utilities in
connection therewith and the same are in a broom-clean condition.

    16.4 Lessor shall use its best efforts to achieve Completion of the 
Improvements on or before the Commencement Date set forth in paragraph 1.5 of 
the Basic Lease Provisions or within one hundred eighty (180) days after Lessor 
obtains the building permit from the applicable building department, whichever 
is later.

    16.5 In the event that the Improvements or any portion thereof have not 
reached Completion by the Commencement Date, this Lease shall not be invalid, 
but rather Lessor shall complete the same as soon thereafter as is possible and 
Lessor shall not be liable to Lessee for damages in any respect whatsoever.

    16.6 If Lessor shall be delayed at any time in the progress of the 
construction of the Improvements or any portion thereof by extra work, changes 
in construction ordered by Lessee, or by strikes, lockouts, fire, delay in 
transportation, unavoidable casualties, rain or weather conditions, governmental
procedures or delay, or by any other cause beyond Lessor's control, then the 
Commencement Date established in paragraph 1.5 of the Lease shall be extended by
the period of such delay.

17. Term

    Upon Completion of the Improvements as defined in paragraph 16.3, above, 
Lessor and Lessee shall execute an amendment to the Lease setting forth the date
of Tender of Possession as defined in paragraph 3.2.1 of the Lease or of actual 
taking of possession, whichever first occurs, as the Commencement Date of this 
Lease.

18. Work Done By Lessee

    Any work done by Lessee shall be done only with Lessor's prior written 
consent and in conformity with a valid building permit and all applicable rules,
regulations, laws and ordinances, and be done in a good and workmanlike manner 
with good and sufficient materials. All work shall be done only with union labor
and only by contractors approved by Lessor, it being understood that all 
plumbing, mechanical, electrical wiring and ceiling work are to be done only by 
contractors designated by Lessor.

19. Taking of Possession of Premises

    Lessor shall notify Lessee of the Estimated Completion Date at least ten 
(10) days before said date. Lessee shall thereafter have the right to enter the 
Premises to commence construction of any Improvements. Lessee is to construct
and to equip and fixturize the Premises, as long as such entry does not
interfere with Lessor's work. Lessee shall take possession of the Premises upon
the tender thereof as provided in paragraph 3.2.1 of the Lease to which this
Work Letter is attached. Any entry by Lessee of the Premises under this
paragraph shall be under all of the terms and provisions of the Lease to which
this Work Letter is attached.

20. Acceptance of Premises

    Lessee shall notify Lessor in writing of any items that Lessee deems 
incomplete or incorrect in order for the Premises to be acceptable to Lessee 
within ten (10) days following Tender of Possession as set forth in paragraph 
3.2.1 of the Lease to which this Work Letter is attached. Lessee shall be 
deemed to have accepted the Premises and approved construction if Lessee does 
not deliver such a list to Lessor within said number of days.

                   ADDENDUM TO STANDARD OFFICE LEASE - GROSS

                 By and Between SILVER GENESIS, INC. (Lessor)
                       and NET VANTAGE INC. (Lessee) for

                           201 Continental Boulevard
                         EL Segundo, California 90245

                             Dated April 10, 1996

4.2  Base Year Operating Expense.  The Base Year Operating Expense shall be 
adjusted to compensate for vacancies in the Building during the Base Year so 
that Operating Expenses shall be based on a 90% occupied building.

4.2  Audit.  The following is hereby added as Section 4.2(h):

"Lessee shall have the right to audit, at Lessee's expense, Operating Expenses 
for the Base Year and each Comparison Year within the twelve (12) month period 
following the calculation of any Operating expense Increase and shall provide 
Lessor with the results of such audit. In the event Lessee has overpaid 
Operating Expenses, Lessor shall refund the amount of the overpayment within 
thirty (30) days. In the event Lessee has underpaid Operating Expenses, Lessee 
shall pay the amount of the underpayment within thirty (30) days."

6.2  Environmental.  Lessor warrants that the Building does not contain any 
Hazardous Substances, as herein defined, in a condition or in amounts which 
exceed legally permissible limits effective as of the date possession is 
delivered to Lessee.

6.2  Compliance with Law. Notwithstanding Section 6.2(b) of the Lease, Lessee 
shall not be required to make structural changes to the Premises or the Building
Systems, unless such changes are related to Lessee's particular use of the 
Premises or improvements constructed by Lessee.

7.2  Lessee's Obligations. Section 6.3(b) is hereby supplemented as follows:

         "Lessee shall have no responsibility to perform or construct any
     repair, maintenance or improvement (i) necessitated by the acts or
     omissions of Lessor or any other occupant of the Building, or their
     respective agents, employees or contractors, (ii) occasioned by a casualty
     not caused or contributed to by Lessee, (iii) required as a consequence of
     any violation of Law in the Premises or the Building as of the date
     possession is delivered to Lessee, (iv) for which Lessor has a right or
     reimbursement from third parties, (v) which would be treated as a capital
     expenditure under generally accepted accounting principals and are
     unrelated to Lessee's particular use of the Premises or improvements
     constructed by Lessee."

7.3  Alterations and Additions. Section 7.3(a) is hereby supplemented as 
follows: 

         "Notwithstanding the foregoing, Lessee shall have the right to make 
     non-structural modifications up to a maximum cost of FIFTEEN THOUSAND
     DOLLARS ($15,000.00) without Lessor's consent. Lessee shall, however, in
     connection with such improvements provide the notice set forth in Section
     7.3(b) in order for Lessor to post a notice of non-responsibility."
     
8.10 Indemnity by Lessor. Notwithstanding anything herein to the contrary,
Lessor shall indemnify and hold harmless Lessee and its agents from and against
all costs, attorneys' fees, expenses and liabilities incurred by Lessee as a
result of the active negligence or willful misconduct of Lessor or Lessor's
failure to perform its obligations hereunder.

<PAGE>
 
12.1  Lessor's Consent Required. Lessor shall provide its written consent, or
      its disapproval of such transfer, within five (5) business days following
      receipt of a written request for approval, together with information
      reasonably requested by Lessor concerning such proposed sublessee or
      assignee, including financial information reasonably requested. In the
      event Lessee is a publicly traded company, the transfer of its stock on
      any exchange or national market system shall not be deemed a Transfer
      under this Section 12.1. The provisions of this Section 12.1 shall not
      prohibit Lessee from entering into licenses with customers or agents of
      customers of Lessee which require space for the purpose of testing or
      inspecting products produced by Lessee, provided such license is temporal
      in nature and does not constitute a grant of exclusive space within the
      Premises by Lessee.

32.   Lessor's Access. Lessor and Lessor's agents shall provide Lessee with
      twenty-four (24) hours' notice prior to entry of the Premises, except in
      the event of an emergency which shall require no notice. Such entry by
      Lessor and Lessor's agents shall not impair Lessee's obligations more than
      reasonably necessary. During any such entry, except emergency entries,
      Lessor and Lessor's agents shall at all times be accompanied by Lessee or
      Lessee's agent. In the event of an emergency entry, Lessor shall use
      reasonable efforts to be accompanied by a representative of Lessee.

49.   Final Calculation of Rentable Square Footage. The Premises, as defined in
      Paragraph 1.2 and the calculation of rent (Paragraph 1.6), security
      deposits (Paragraph 1.9) and Lessee's share of operating expenses
      (Paragraph 1.10) shall be computed upon $1.06 per rentable square foot
      pursuant to the final approved space plan. Rentable square footage shall
      be computed based upon the usable square feet multiplied by 1.15% (15%
      load factor). The vehicle parking spaces allocated to Lessee pursuant to
      Paragraph 2.2 shall be based upon 1,000 square feet of usable area. In the
      event a discrepancy is determined regarding the square footage of the
      Premises, the foregoing amounts may be adjusted, provided that in the
      event shall either party be entitled to any retroactive adjustment whether
      for operating expenses, rent or parking.

50.   Right of First Notice of Lease. In the event that space on the second
      floor becomes available for lease during the term of Lessee's Lease,
      Lessor shall notify Lessee of the availability of such space. Lessee shall
      have ten (10) working days to provide Lessor with written notice of its
      desire to negotiate a lease for the available space. In the event Lessee
      provides Lessor with written notice of its desire to negotiate a lease for
      such space, Lessor and Lessee shall negotiate in good faith the terms of
      the lease for the available space for the thirty (30) day period following
      receipt of Lessee's election to negotiate. In no event shall this right of
      first notice provide Lessee with an option to lease such other space or a
      right of first refusal. Lessor shall have the right to market such
      expansion space, despite Lessee's election, but shall negotiate in good
      faith with Lessee concerning a lease for such expansion space. Upon
      written notice by Lessor to Lessee of the date of availability of the
      proposed space, Lessee shall have ten (10) working days to enter a thirty
      (30) day period of "good faith" negotiations.

51.   Option to Renew Lease. Lessee is given the option to extend the term on
      all the provisions contained in this lease, except for minimum monthly
      rent, for a five (5) year period ("Extended Term") following expiration of
      the initial term, by giving notice of exercise of the option ("Option
      Notice") to Lessor at least six (6) months, but not more than one (1) year
      before the expiration of the term. Provided that, if Lessee is in default
      on the date of giving the Option Notice, the Option Notice shall be
      totally ineffective, or if Lessee is in

                                      -2-
<PAGE>
 
     default on the date the Extended Term is to commence, the Extended Term
     shall not commence and this lease shall expire at the end of the initial
     term.

     The parties shall have thirty (30) days after Lessor receives the Option
     Notice in which to agree on Base Rent during the Extended Term. If the
     parties agree on the Base Rent for the Extended Term during that period,
     they shall immediately execute an amendment to this lease stating the Base
     Rent.

     If the parties are unable to agree on the Base Rent for the Extended Term
     within that period, then within ten (10) days after the expiration of that
     period each party, at its cost and by giving notice to the other party,
     shall appoint a real estate appraiser with at least 5 years' full-time
     commercial appraisal experience in the area in which the premises are
     located to appraise and set the Base Rent for the Extended Term based upon
     ninety-five percent (95%) of the fair market rental for the Premises based
     upon the prevailing market rates for similar space in similar buildings. If
     a party does not appoint an appraiser within ten (10) days after the other
     party has given notice of the name of its appraiser, the single appraiser
     appointed shall be the sole appraiser and shall set the Base Rent for the
     Extended Term. If the two appraisers are appointed by the parties as stated
     in this paragraph, they shall meet promptly and attempt to set the Base
     Rent for the Extended Term. If they are unable to agree within thirty (30)
     days after the second appraiser has been appointed, they shall attempt to
     elect a third appraiser meeting the qualifications stated in this paragraph
     within ten (10) days after the last day the two appraisers are given to set
     the Base Rent. If they are unable to agree on the third appraiser, either
     of the parties to this lease by giving ten (10) days' notice to the other
     party can file a petition with the American Arbitration Association solely
     for the purpose of selecting a third appraiser who meets the qualifications
     stated in this paragraph. Each party shall bear half the cost of the
     American Arbitration Association appointing the third appraiser and of
     paying the third appraiser's fee. The third appraiser, however selected,
     shall be a person who has not previously acted in any capacity for either
     party.

     Within thirty (30) days after the selection of the third appraiser, a
     majority of the appraisers shall set the Base Rent for the Extended Term.
     If a majority of the appraisers are unable to set the Base Rent within the
     stipulated period of time, the three appraisals shall be added together and
     their total divided by three; the resulting quotient shall be the Base Rent
     for the premises during the Extended Term. If, however, the low appraisal
     and/or the high appraisal are more than ten percent (10%) lower and/or
     higher than the middle appraisal, the low appraisal and/or the high
     appraisal shall be disregarded. If only one appraisal is disregarded, the
     remaining two appraisals shall be added together and their total divided by
     two; the resulting quotient shall be the Base Rent for the premises during
     the Extended Term. If both the low appraisal and the high appraisal are
     disregarded as stated in this paragraph, the middle appraisal shall be the
     Base Rent for the premises during the Extended Term.

     After the Base Rent for the Extended Term has been set, the appraisers
     shall immediately notify the parties.

     Lessee shall have no other right to extend the term beyond the Extended
     Term.

52.  Increases in Property Taxes During the First Three (3) Years of the Lease
     Term. During the first three (3) years of the initial lease term, Lessee
     shall not be responsible for any increases in property taxes resulting from
     the reassessment of the property caused by a sale of the property by Lessor
     ("Proposition 13").

                                      -3-
<PAGE>
 
53.  Signage.  Lessee shall have the right to install its sign on one (1)
     position of the shared monument sign at the parking lot entrance to the
     property. All signage is subject to City of El Segundo approval.

54.  Microwave Dish.  Lessee may install a microwave dish on the roof of the 
     Premises subject to Lessor's reasonable approval and in a location of
     Lessor's reasonable discretion.

55.  Non-Disturbance Agreements.  Lessor shall use commercially reasonable 
     efforts to obtain promptly following the execution of the Lease, non-
     disturbance, subordination and attornment agreements from Lessor's lender
     in a form reasonably satisfactory to Lessor's lender, Lessor and Lessee.
     Lessor and Lessee shall use reasonable and diligent efforts to satisfy the
     foregoing obligation.

56.  Early Possession of Lessee's Construction Work.  Lessor shall grant Lessee 
     early possession of the Premises upon mutual execution of this Lease in its
     existing condition. During this period up to the commencement date of the
     Lease (February 1, 1997), all terms of this Lease shall be in effect with
     the exception of the payment of Base Rent. Irrespective of Lessee's
     occupancy, the payment of Base Rent and the calculation of the initial term
     shall begin February 1, 1997. Lessee acknowledges that Lessor is completing
     a refurbishment of the Building simultaneously with Lessee's completing its
     improvements. Lessee shall complete the improvements to the Premises in
     conformance with the Floor Plan attached to the Lease as Exhibit "A".
                                                              -----------
     Lessor and Lessee shall use reasonable and diligent efforts to promptly 
     complete their respective improvements.  All such improvements shall be 
     substantially completed on or before November 1, 1996.

this Lease, in which event the parties shall be discharged from all obligations 
hereunder; provided, however, that, as to Lessee's obligations, Lessee first 
reimburses-Lessor for all costs incurred for Non-Standard Improvements and, as 
to Lessor's obligations, Lessor shall return any money previously deposited by 
Lessee (less any offsets due Lessor for Non-Standard Improvements); and provided
further, that if such written notice by Lessee is not received by Lessor within 
said ten (10) day period. Lessee's right to cancel this Lease hereunder shall 
terminate and be of no further force or effect.

      3.2.1 Possession Tendered-Defined. Possession of the Premises shall be 
deemed tendered to Lessee upon mutual execution("Tender of Possession")

      3.2.2 Delays Caused by Lessee. There shall be no abatement of rent, and

right to cancel this Lease accrues under paragraph 3.2, shall be deemed extended
to the extent of any delays caused by acts of omissions of Lessee, Lessee's 
agents, employees and contractors.

   3.3 Early Possession. If Lessee occupies the Premises prior to said 
Commencement Date, such occupancy shall be subject to all provisions of this 
Lease, such occupancy shall not change the termination date, and Lessee shall 
pay rent for such occupancy.

defined as the completion of the improvements, Lessee and Lessor shall execute 
an amendment to this Lease establishing the date of Tender of Possession (as 
defined in paragraph 3.2.1) or the actual taking of possession by Lessee, 
whichever first occurs, as the Commencement Date.

4. Rent.

   4.1 Base Rent. Subject to adjustment as hereinafter provided in paragraph 
4.3, and except as may be otherwise expressly provided in this Lease, Lessee 
shall pay to Lessor the Base Rent for the Premises set forth in paragraph 1.6 of
the Basic Lease Provisions, without offset or deduction. Lessee shall pay Lessor
upon execution hereof the advance Base Rent described in paragraph 1.8 of the 
Basic Lease Provisions. Rent for any period during the term hereof which is for 
less than one month shall be prorated based upon the actual number of days of 
the calendar month involved. Rent shall be payable in lawful money of the United
States to Lessor at the address stated herein or to such other persons or at 
such other places as Lessor may designate in writing.

   4.2 Operating Expense Increase. Lessee shall pay to Lessor during the term
hereof, in addition to the Base Rent, Lessee's Share, as hereinafter defined, of
the amount by which all Operating Expenses, as hereinafter defined, for each 
Comparison Year exceeds the amount of all Operating Expenses for the Base Year, 
such excess being hereinafter referred to as the "Operating Expense Increase," 
in accordance with the following provisions:

       (a) "Lessee's Share" is defined, for purposes of this Lease, as the
percentage set forth in paragraph 1.10 of the Basic Lease Provisions, which
percentage has been determined by dividing the approximate square footage of the
Premises by the total approximate square footage of the rentable space contained
in the Office Building Project. It is understood and agreed that the square 
footage figures set forth in the Basic Lease Provisions are approximations which
Lessor and Lessee agree are reasonable and shall not be subject to revision 
except in connection with an actual change in the size of the Premises or a 
change in the space available for lease in the Office Building Project.

       (b) "Base Year" is defined as the first twelve (12) months of occupancy.

       (c) "Comparison Year" is defined as each calendar year during the term of
this Lease subsequent to the Base Year; provided, however, Lessee shall have no 
obligation to pay a share of the Operating Expense increase applicable to the
first twelve (12) months of the Lease Term (other than such as are mandated by a
governmental authority, as to which government mandated expenses Lessee shall
pay Lessee's Share, notwithstanding they occur during the first twelve (12)
months). Lessee's Share of the Operating Expense Increase for the first and last
Comparison Years of the Lease Term shall be prorated according to that portion
of such Comparison Year as to which Lessee is responsible for a share of such
increase.

       (d) "Operating Expenses" is defined, for purposes of this Lease, to 
include all costs, if any, incurred by Lessor in the exercise of its reasonable 
discretion, for:

            (i)  The operation, repair, maintenance, and replacement, in neat, 
clean, safe, good order and condition, of the Office Building Project, including
but not limited to, the following:

               (aa) The Common Areas, including their surfaces, covering, 
decorative items, carpets, drapes and window coverings, and including parking 
areas, loading and unloading areas, trash areas, roadways, sidewalks, walkways, 
stairways, parkways, driveways, landscaped areas, striping, bumpers, irrigation 
systems, Common Area lighting facilities, building exteriors and roofs, fences 
and gates;

               (bb) All heating, air conditioning, plumbing, electrical systems,
life safety equipment, telecommunication and other equipment used in common by, 
or for the benefit of, lessees or occupants of the Office Building Project, 
including elevators and escalators, tenant directories, fire detection systems 
including sprinkler system maintenance repair.

            (ii)   Trash disposal, janitorial and security services;

            (iii)  Any other service to be provided by Lessor that is elsewhere
in this Lease stated to be an "Operating Expense";

            (iv)   The cost of the premiums for the liability and property
insurance policies to be maintained by Lessor under paragraph 8 hereof;

            (v)    The amount of the real property taxes to be paid by Lessor 
under paragraph 10.1 hereof;

            (vi)   The cost of water, sewer, gas, electricity, and other 
publicly mandated services to the Office Building Project;

            (vii)  Labor, salaries and applicable fringe benefits and costs, 
materials, supplies and tools, used in maintaining and/or cleaning the Office 
Building Project and accounting and a management fee attributable to the 
operation of the Office Building Project;

            (viii) Replacing and/or adding improvements mandated by any
governmental agency and any repairs or removals necessitated thereby amortized
over its useful life according to Federal Income tax regulations or guidelines
for depreciation thereof (including interest on the unamortized balance as is
then reasonable in the judgment of Lessor's accountants);

            (ix)   Replacements of equipment or improvements that have a useful 
life for depreciation purposes according to Federal income tax guidelines of 
five (5) years or less, as amortized over such life.

       (e) Operating Expenses shall not include the costs of replacements of 
equipment or improvements that have a useful life for Federal income tax 
purposes in excess of five (5) years unless it is of the type described in 
paragraph 4.2(d)(viii), in which case their cost shall be included as above 
provided.

       (f) Operating Expenses shall not include any expenses paid by any lessee 
directly to third parties, or as to which Lessor is otherwise reimbursed by any 
third party, other tenant, or by insurance proceeds.

       (g) Lessee's Share of Operating Expense Increase shall be payable by
Lessee within thirty (30) days after a reasonably detailed statement of actual
expenses is presented to Lessee by Lessor. At Lessor's option, however, an
amount may be estimated by Lessor from time to time in advance of Lessee's Share
of the Operating Expense Increase for any Comparison Year, and the same shall be
payable monthly or quarterly, as Lessor shall designate, during each Comparison
Year of the Lease term, on the same day as the Base Rent is due hereunder. In
the event that Lessee pays Lessor's estimate of Lessee's Share of Operating
Expense Increase as aforesaid, Lessor shall deliver to Lessee within sixty (60)
days after the expiration of each Comparison Year a reasonably detailed
statement showing Lessee's Share of the actual Operating Expense Increase
incurred during such year. If Lessee's payments under this paragraph 4.2(g)
during said Comparison Year exceed Lessee's Share as indicated on said
statement, Lessee shall be entitled to credit the amount of such overpayment
against Lessee's Share of Operating Expense Increase next falling due. If
Lessee's payments under this paragraph during said Comparison Year were less
than Lessee's Share as indicated on said statement, Lessee shall pay to Lessor
the amount of the deficiency within ten (10) days after delivery by Lessor to
Lessee of said statement. Lessor and Lessee shall forthwith adjust between them
by cash payment any balance determined to exist with respect to that portion of
the last Comparison Year for which Lessee is responsible as to Operating Expense
increases, notwithstanding that the Lease term may have terminated before the
end of such Comparison Year.

   4.3 Rent Increase.

       4.3.1 At the times set forth in paragraph 1.7 of the Basic Lease 
Provisions, the monthly Base Rent payable under paragraph 4.1 of this Lease 
shall be adjusted by the increase, if any, in the Consumer Price Index of the 
Bureau of Labor Statistics of the Department of Labor for All Urban Consumers. 
(1967=100), "All Items," for the city nearest the location of the 
Building, herein referred to as "C.P.I.", since the date of this Lease.

       4.3.2 The monthly Base Rent payable pursuant to paragraph 4.3.1 shall be 
calculated as follows: the Base Rent payable for the first month of the term of 
this Lease, as set forth in paragraph 4.1 of this Lease, shall be multiplied by 
a fraction the numerator of which shall be the C.P.I. of the calendar month 
during which the adjustment is to take effect, and the denominator of which 
shall be the C.P.I. for the calendar month in which the original Lease term 
commences. The sum so calculated shall constitute the new monthly Base Rent 
hereunder, but, in no event, shall such new monthly Base Rent be less than the 
Base Rent payable for the month immediately preceding the date of the rent 
adjustment.

         4.3.5  At such time as the amount of any change in rental required by
this Lease is known or determined, Lessor and Lessee shall execute an amendment
to this Lease setting forth such change.

5.  Security Deposit. Lessee shall deposit with Lessor upon execution hereof the
security deposit set forth in paragraph 1.9 of the Basic Lease Provisions as 
security for Lessee's faithful performance of Lessee's obligations hereunder. If
Lessee fails to pay rent or other charges due hereunder, or otherwise defaults 
with respect to any provision of this Lease, Lessor may use, apply or retain all
or any portion of said deposit for the payment of any rent or other charge in 
default for the payment of any other sum to which Lessor may become obligated by
reason of Lessee's default, or to compensate Lessor for any loss or damage which
Lessor may suffer thereby. If Lessor so uses or applies all or any portion of 
said deposit, Lessee shall within ten (10) days after written demand therefor 
deposit cash with Lessor in an amount sufficient to restore said deposit to the 
full amount then required of Lessee. Lessor shall not be required to keep said 
security deposit separate from its general accounts. If Lessee performs all of 
Lessee's obligations hereunder, said deposit, or so much thereof as has not 
heretofore been applied by Lessor, shall be returned, without payment of 
interest or other increment for its use, to Lessee (or, at Lessor's option, to 
the last assignee, if any, of Lessee's interest hereunder) within thirty (30) 
days following the expiration of the term hereof, and the date Lessee has 
vacated the Premises. No trust relationship is created herein between Lessor and
Lessee with respect to said Security Deposit.

6.  Use.

    6.1  Use. The Premises shall be used and occupied only for the purpose set 
forth in paragraph 1.4 of the Basic Lease Provisions or any other use which is 
reasonably comparable to that use.

    6.2  Compliance with Law.

         (a) Lessor warrants to Lessee that the Premises, in the state existing 
on the date that the Lease term commences, but without regard to alterations or 
improvements made by Lessee or the use for which Lessee will occupy the 
Premises, does not violate any covenants or restrictions of record, or any 
applicable building code, regulation or ordinance or applicable laws in effect 
on such Lease term Commencement Date. In the event it is determined that this 
warranty has been violated, then it shall be the obligation of the Lessor, after
written notice from Lessee, to promptly, at Lessor's sole cost and expense, 
rectify any such violation.

         (b) Except as provided in paragraph 6.2(a) Lessee shall, at Lessee's 
expense, promptly comply with all applicable statutes, ordinances, rules, 
regulations, orders, covenants and restrictions of record, and requirements of 
any fire insurance underwriters or rating bureaus, now in effect or which may 
hereafter come into effect, whether or not they reflect a change in policy from 
that now existing, during the term or any part of the term hereof, relating in 
any manner to the Premises and the occupation and use by Lessee of the Premises.
Lessee shall conduct its business in a lawful manner and shall not use or permit
the use of the Premises or the Common Areas in any manner that will tend to 
create waste or a nuisance or shall tend to disturb other occupants of the 
Office Building Project.

    6.3  Condition of Premises.

         (a) Lessor shall deliver the Premises to Lessee in a clean condition on
the Lease Commencement Date (unless Lessee is already in possession) and Lessor 
warrants to Lessee that the plumbing, lighting, air conditioning, and heating 
system, electrical systems, elevators and all building systems in the Premises 
shall be in good operating condition. In the event that it is determined that 
this warranty has been violated, then it shall be the obligation of Lessor, 
after receipt of written notice from Lessee setting forth with specificity the 
nature of the violation, to promptly, at Lessor's sole cost, rectify such 
violation.

         (b) Except as otherwise provided in this Lease, Lessee hereby accepts 
the Premises and the Office Building Project in their condition existing as of 
the Lease Commencement Date or the date that Lessee takes possession of the 
Premises, whichever is earlier, subject to all applicable zoning, municipal, 
county and state laws, ordinances and regulations governing and regulating the 
use of the Premises, and any easements, covenants or restrictions of record, and
accepts this Lease subject thereto and to all matters disclosed thereby and by 
any exhibits attached hereto. Lessee acknowledges that it has satisfied itself
by its own independent investigation that the Premises are suitable for its
intended use, and that neither Lessor nor Lessor's agent or agents has made any
representation or warranty as to the present or future suitability of the
Premises, Common Areas, or Office Building Project for the conduct of Lessee's
business.

7.  Maintenance, Repairs, Alterations and Common Area Services.

    7.1  Lessor's Obligations. Lessor shall keep the Office Building Project, 
including the Premises, interior and exterior walls, roof, and common areas, and
the equipment whether used exclusively for the Premises or in common with other 
premises, in good condition and repair; provided, however, Lessor shall not be 
obligated to paint, repair or replace wall coverings, or to repair or replace 
any improvements that are not ordinarily a part of the Building or are above 
then Building standards. Except as provided in paragraph 9.5 there shall be no 
abatement of rent or liability of Lessee on account of any injury or 
interference with Lessee's business with respect to any improvements, 
alterations or repairs made by Lessor to the Office Building Project or any part
thereof. Lessee expressly waives the benefits of any statute now or hereafter in
effect which would otherwise afford Lessee the right to make repairs at Lessor's
expense or to terminate this Lease because of Lessor's failure to keep the 
Premises in good order, condition and repair.

    7.2  Lessee's Obligations. 

         (a) Notwithstanding Lessor's obligation to keep the Premises in good 
condition and repair, Lessee shall be responsible for payment of the cost 
thereof to Lessor as additional rent for that portion of the cost of any 
maintenance and repair of the Premises, or any equipment (wherever located) that
serves only Lessee or the Premises, to the extent such cost is attributable to 
causes beyond normal wear and tear. Lessee shall be responsible for the cost of 
painting, repairing or replacing wall coverings, and to repair or replace any 
Premises improvements that are not ordinarily a part of the Building or that are
above then Building standards. Lessor may, at its option, upon reasonable
notice, elect to have Lessee perform any particular such maintenance or repairs
the cost of which is otherwise Lessee's responsibility hereunder.

         (b) On the last day of the term hereof, or on any sooner termination, 
subject to all provisions of this Lease regarding the condition of the Premises,
Lessee shall surrender the Premises to Lessor in the same condition as received,
ordinary wear and tear excepted, clean and free of debris. Any damage or 
deterioration of the Premises shall not be deemed ordinary wear and tear if the 
same could have been prevented by good maintenance practices by Lessee. Lessee 
shall repair any damage to the Premises occasioned by the installation or 
removal of Lessee's trade fixtures, alterations, furnishings and equipment. 
Except as otherwise stated in this Lease, Lessee shall leave the air lines, 
power panels, electrical distribution systems, lighting fixtures, air 
conditioning, window coverings, wall coverings, carpets, wall panelling, 
ceilings and plumbing on the Premises and in good operating condition.

    7.3  Alterations and Additions.

         (a) Lessee shall not, without Lessor's prior written consent make any 
alterations, improvements, additions, Utility Installations or repairs in, on or
about the Premises, or the Office Building Project. As used in this paragraph 
7.3 the term "Utility Installation" shall mean carpeting, window and wall 
coverings, power panels, electrical distribution systems, lighting fixtures, air
conditioning, plumbing, and telephone and telecommunication wiring and 
equipment. At the expiration of the term, Lessor may require the removal of any 
or all of said alterations, improvements, additions or Utility Installations, 
and the restoration of the Premises and the Office Building Project to their 
prior condition, at Lessee's expense. Should Lessor permit Lessee to make its 
own alterations, improvements, additions or Utility Installations, Lessee shall 
use only such contractor as has been expressly approved by Lessor, and Lessor 
may require Lessee to provide Lessor, at Lessee sole cost and expense, a lien 
and completion bond involving improvements, additions or Utility Installations 
costing in excess of $100,000.00. In calculating the foregoing amount, amounts 
incurred under the Primary Lease shall be aggregated with amounts incurred 
hereunder. In addition, for purposes of the Primary Lease, costs incurred
hereunder shall be aggregated with the costs incurred under the Primary Leases
in an amount equal to one and one-half times the estimated cost of such
improvements, to insure Lessor against any liability for mechanic's and
materialmen's liens and to insure completion of the work. Should Lessee make any
alterations, improvements, additions or Utility Installations without the prior
approval of Lessor, or use a contractor not expressly approved by Lessor, Lessor
may, at any time during the term of this Lease, require that Lessee remove any
part or all of the same.

         (b) Any alterations, improvements, additions or Utility Installations 
in or about the Premises or the Office Building Project that Lessee shall desire
to make shall be presented to Lessor in written form, with proposed detailed 
plans. If Lessor shall give its consent to Lessee's making such alteration, 
improvement, addition or Utility Installation, the consent shall be deemed 
conditioned upon Lessee acquiring a permit to do so from the applicable 
governmental agencies, furnishing a copy thereof to Lessor prior to the 
commencement of the work, and compliance by Lessee with all conditions of said 
permit in a prompt and expeditious manner.

         (c) Lessee shall pay, when due, all claims for labor or materials 
furnished or alleged to have been furnished to or for Lessee at or for use in 
the Premises, which claims are or may be secured by any mechanic's or 
materialmen's lien against the Premises, the Building or the Office Building 
Project, or any interest therein.

         (d) Lessee shall give Lessor not less than ten (10) days' notice prior 
to the commencement of any work in the Premises by Lessee, and Lessor shall have
the right to post notices of non-responsibility in or on the Premises or the 
Building as provided by law. If Lessee shall, in good faith, contest the 
validity of any such lien, claim or demand, then Lessee shall, at its sole 
expense defend itself and Lessor against the same and shall pay and satisfy

any such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Premises, the Building or the Office Building
Project, upon the condition that if Lessor shall require, Lessee shall furnish
to Lessor a surety bond satisfactory to Lessor in an amount equal to such
contested lien claim or demand indemnifying Lessor against liability for the
same and holding the Premises, the Building and the Office Building Project free
from the effect of such lien or claim. In addition, Lessor may require Lessee to
pay Lessor's reasonable attorneys' fees and costs in participating in such
action if Lessor shall decide it is to Lessor's best interest so to do.

         (e) All alterations, improvements, additions and Utility Installations
(whether or not such Utility Installations constitute trade fixtures of Lessee),
which may be made to the Premises by Lessee, including but not limited to, floor
coverings, panelings, doors, drapes, built-ins, moldings, sound attenuation, and
lighting and telephone or communication systems, conduit, wiring and outlets,
shall be made and done in a good and workmanlike manner and of good and
sufficient quality and materials and shall be the property of Lessor and remain
upon and be surrendered with the Premises at the expiration of the Lease term,
unless Lessor requires their removal pursuant to paragraph 7.3(a). Provided
Lessee is not in default, notwithstanding the provisions of this paragraph
7.3(e), Lessee's personal property and equipment other than that which is
affixed to the Premises so that it cannot be removed without material damage to
the Premises or the Building, and other than Utility Installations, shall remain
the property of Lessee and may be removed by Lessee subject to the provisions of
paragraph 7.2.

         (f) Lessee shall provide Lessor with as-built plans and specifications
for any alterations, improvements, additions or Utility Installations.

    7.4  Utility Additions.  Lessor reserves the right to install new or 
additional utility facilities throughout the Office Building Project for the 
benefit of Lessor or Lessee, or any other lessee of the Office Building Project,
including, but not by way of limitation, such utilities as plumbing, electrical 
systems, communication systems, and fire protection and detection systems, so 
long as such installations do not unreasonably interfere with Lessee's use of 
the Premises.

8.  Insurance: Indemnity.

    8.1  Liability Insurance--Lessee.  Lessee shall at Lessee's expense, obtain
and keep in force during the term of this Lease a policy of Comprehensive 
General Liability insurance utilizing an Insurance Services Office standard form
with Broad Form General Liability Endorsement (GL0404), or equivalent, in an 
amount of not less than $1,000,000 per occurrence of bodily injury and property 
damage combined or in a greater amount as reasonably determined by Lessor and 
shall insure Lessee with Lessor as an additional insured against liability 
arising out of the use, occupancy or maintenance of the Premises.  Compliance 
with the above requirement shall not, however, limit the liability of Lessee 
hereunder.

    8.2  Liability Insurance--Lessor.  Lessor shall obtain and keep in force 
during the term of this Lease a policy of Combined Single Limit Bodily Injury 
and Broad Form Property Damage Insurance, plus coverage against such other risks
Lessor deems advisable from time to time, insuring Lessor, but not Lessee,
against liability arising out of the ownership, use, occupancy or maintenance of
the Office Building Project in an amount not less than $5,000,000.00 per
occurrence.

    8.3  Property Insurance--Lessee. Lessee shall, at Lessee's expense, obtain 
and keep in force during the term of this Lease for the benefit of Lessee, 
replacement cost fire and extended coverage insurance, with vandalism and 
malicious mischief, sprinkler leakage and earthquake sprinkler leakage, 
endorsements, in an amount sufficient to cover not less than 100% of the full 
replacement cost, as the same may exist from time to time, of all of Lessee's 
personal property, fixtures, equipment and tenant improvements.

    8.4  Property Insurance--Lessor. Lessor shall obtain and keep in force 
during the term of this Lease a policy or policies of insurance covering loss or
damage to the Office Building Project improvements, but not Lessee's personal 
property, fixtures, equipment or tenant improvements in the amount of the full 
replacement cost thereof, as the same may exist from time to time, utilizing 
Insurance Services Office standard form, or equivalent, providing protection 
against all perils included within the classification of fire, extended 
coverage, vandalism, malicious mischief, plate glass, and such other 
perils as Lessor deems advisable or may be required by a lender having a lien on
the Office Building Project. In addition, Lessor shall obtain and keep in force,
during the term of this Lease, a policy rental value insurance covering a period
of one year, with loss payable to Lessor, which insurance shall also cover all 
Operating Expenses for said period. Lessee will not be named in any such 
policies carried by Lessor and shall have no right to any proceeds therefrom. 
The policies required by these paragraphs 8.2 and 8.4 shall contain such 
deductibles as Lessor or the aforesaid lender may determine. In the event that 
the Premises shall suffer an insured loss as defined in paragraph 9.1(f) hereof,
the deductible amounts under the applicable insurance policies shall be deemed
an Operating Expense. Lessee shall not do or permit to be done anything which
shall invalidate the insurance policies carried by Lessor. Lessee shall pay the
entirety of any increase in the property insurance premium for the Office 
Building Project over what it was immediately prior to the commencement of the 
term of this Lease if the increase is specified by Lessor's insurance carrier as
being caused by the nature of Lessee's occupancy or any act or omission of 
Lessee.

    8.5  Insurance Policies. Lessee shall deliver to Lessor copies of liability 
insurance policies required under paragraph 8.1 or certificates evidencing the 
existence and amounts of such insurance within seven (7) days after the 
Commencement Date of this Lease. No such policy shall be cancellable or subject 
to reduction of coverage or other modification except after thirty (30) days 
prior written notice to Lessor. Lessee shall, at least thirty (30) days prior to
the expiration of such policies, furnish Lessor with renewals thereof.

    8.6  Waiver of Subrogation. Lessee and Lessor each hereby release and 
relieve the other, and waive their entire right of recovery against the other, 
for direct or consequential loss or damage arising out of or incident to the 
perils covered by property insurance carried by such party, whether due to the 
negligence of Lessor or Lessee or their agents, employees, contractors and/or 
invitees. If necessary all property insurance policies required under this Lease
shall be endorsed to so provide.

    8.7  Indemnity. Lessee shall indemnify and hold harmless Lessor and its 
agents, Lessor's master or ground lessor, partners and lenders, from and against
any and all claims for damage to the person or property of anyone or any entity 
arising from Lessee's use of the Office Building Project, or from the conduct of
Lessee's business or from any activity, work or things done, permitted or 
suffered by Lessee in or about the Premises or elsewhere and shall further 
indemnify and hold harmless Lessor from and against any and all claims, costs 
and expenses arising from any breach or default in the performance of any 
obligation or Lessee's part to be performed under the terms of this Lease, or 
arising from any act or omission of Lessee, or any of Lessee's agents, 
contractors, employees, or invitees, and from and against all costs, attorney's 
fees, expenses and liabilities incurred by Lessor as the result of any such use,
conduct, activity, work, things done, permitted or suffered, breach, default or
negligence, and in dealing reasonably therewith, including but not limited to 
the defense or pursuit of any claim or any action or proceeding involved 
therein; and in case any action or proceeding be brought against Lessor by 
reason of any such matter, Lessee upon notice from Lessor shall defend the same 
at Lessee's expense by counsel reasonably satisfactory to Lessor and Lessor
shall cooperate with Lessee in such defense. Lessor need not have first paid any
such claim in order to be so indemnified. Lessee as a material part of the 
consideration to Lessor, hereby assumes all risk of damage to property of Lessee
or injury to persons, in, upon or about the Office Building Project arising from
any cause and Lessee hereby waives all claims in respect thereof against Lessor.

    8.8  Exemption of Lessor from Liability. Lessee hereby agrees that Lessor
shall not be liable for injury to Lessee's business or any loss of income
therefrom or for loss of or damage to the goods, wares, merchandise or other
property of Lessee, Lessee's employees, invitees, customers, or any other person
in or about the Premises or the Office Building Project, nor shall Lessor be
liable for injury to the person of Lessee, Lessee's employees, agents or
contractors, whether such damage or injury is caused by or results from theft,
fire steam, electricity, gas, water or rain, or from the breakage leakage,
obstruction or other defects of pipes, sprinklers, wires, appliances, plumbing,
air conditioning or lighting fixtures, or from any other cause, whether said
damage or injury results from conditions arising upon the Premises or upon other
portions of the Office Building Project, or from other sources or places, or
from new construction or the repair, alteration or improvement of any part of
the Office Building Project, or of the equipment, fixtures, or appurtenances
applicable thereto, and regardless of whether the cause of such damage or injury
or the means of repairing the same is inaccessible, Lessor shall not be liable
for any damages arising from any act or neglect of any other lessee, occupant or
user of the Office Building Project, nor from the failure of Lessor to enforce
the provisions of any other lease of any other lessee of the Office Building
Project.

    8.9  No Representation of Adequate Coverage. Lessor makes no representation 
that the limits or forms of coverage of insurance specified in this paragraph 8 
are adequate to cover Lessee's property or obligations under this lease.

9.  Damage or Destruction.

destroyed to any extent.

         (b) "Premises Building Partial Damage" shall mean if the Building of 
which the Premises are a part is damaged or destroyed to the extent that the 
cost to repair is less than fifty percent (50%) of the then Replacement Cost of 
the building.

         (c) "Premises Building Total Destruction" shall mean if the Building of
which the Premises are a part is damaged or destroyed to the extent that the

         (f) "Insured Loss" shall mean damage or destruction which was caused by
an event required to be covered by the insurance described in paragraph 8. The 
fact that an insured Loss has a deductible amount shall not make the loss an 
uninsured loss.

         (g) "Replacement Cost" shall mean the amount of money necessary to be 
spent in order to repair or rebuild the damaged area to the condition that 
existed immediately prior to the damage occurring, excluding all improvements

         (a) Insured Loss: Subject to the provisions of paragraphs 9.4 and 9.5,
if at any time during the term of this Lease there is damage which is an
Insured Loss and which falls into the classification of either Premises Damage
or Premises Building Partial Damage, then Lessor shall, as soon as reasonably
possible and to the extent the required materials and labor are readily
available through usual commercial channels, at Lessor's expense, repair such 
damage (but not Lessee's fixtures, equipment or tenant improvements originally 
paid for by Lessee) to its condition existing at the time of the damage, and 
this Lease shall continue in full force and effect.

         (b) Uninsured Loss; Subject to the provisions of paragraphs 9.4 and
9.5, if at any time during the term of this Lease there is damage which is not
an insured Loss and which falls within the classification of Premises Damage or 
Premises Building Partial Damage, unless caused by a negligent or willful act of
Lessee (in which event Lessee shall make the repairs at Lessee's expense), which
damage prevents Lessee from making any substantial use of the Premises, Lessor 
may at Lessor's option either (i) repair such damage as soon as reasonably 
possible at Lessor's expense, in which event this Lease shall continue in full 
force and effect, or (ii) to the extent such Premises Damage exceeds five 
percent (5%) of the Replacement Cost of the Building give written notice to 
Lessee within thirty (30) days after the date of the occurrence of such damage

date of the occurrence of such damage.

    9.3  Premises Building Total Destruction; Office Building Project Total

at Lessor's option either (i) repair such damage or destruction as soon as 
reasonably possible at Lessor's expense (to the extent the required materials 
are readily available through usual commercial channels) to its condition 
existing at the time of the damage, but not Lessee's fixtures, equipment or 
tenant improvements, and this Lease shall continue in full force and effect, or 
(ii) give written notice to Lessee within thirty (30) days after the date of 
occurrence of such damage of Lessor's intention to cancel and terminate this 
Lease, in which case this Lease shall terminate as of the date of the occurrence
of such damage.

    9.4  Damage Near End of Term.

         (a) Subject to paragraph 9.4(b), if at any time during the last twelve 
(12) months of the term of this Lease there is substantial damage to the 
Premises which exceeds five percent (5%) of the Replacement Cost of the Building
Lessor may at Lessor's option cancel and terminate this Lease as of the date of 
occurrence of such damage by giving written notice to Lessee of Lessor's 
election to do so within 30 days after the date of occurrence of such damage.

         (b) Notwithstanding paragraph 9.4(a), in the event that Lessee has an 
option to extend or renew this Lease, and the time within which said option may 
be exercised has not yet expired. Lessee shall exercise such option, if it is 
to be exercised at all, no later than twenty (20) days after the occurrence of 
an insured Loss falling within the classification of Premises Damage during the 
last twelve (12) months of the term of this Lease. If Lessee duly exercises 
such option during said twenty (20) day period, Lessor shall, at Lessor's 
expense, repair such damage, but not Lessee's fixtures, equipment or tenant 
improvements, as soon as reasonably possible and this Lease shall continue in

this Lease as of the expiration of said twenty (20) day period by giving written
notice to Lessee of Lessor's election to do so within ten (10) days after the 
expiration of said twenty (20) day period, notwithstanding any term or provision
in the grant of option to the contrary.

    9.5  Abatement of Rent; Lessee's Remedies.

         (a) In the event Lessor repairs or restores the Building or Premises 
pursuant to the provisions of this paragraph 9, and any part of the Premises are
not usable (including loss of use due to loss of access or essential services), 
the rent payable hereunder (including Lessee's Share of Operating Expense 
increase) for the period during which such damage, repair or restoration 
continues shall be abated, provided (1) the damage was not the result of the 
negligence of Lessee, and (2) such abatement shall only be to the extent the 
operation and profitability of Lessee's business as operated from the Premises
is adversely affected. Except for said abatement of rent, if any, Lessee shall
have no claim against Lessor for any damage suffered by reason of any such
damage, destruction, repair or restoration.

         (b) If Lessor shall be obligated to repair or restore the Premises or
the Building under the provisions of this Paragraph 9 and shall not commence
such repair or restoration within ninety (90) days after such occurrence, or if
Lessor shall not complete the restoration and repair within six (6) months after
such occurrence, Lessee may at Lessee's option cancel and terminate this Lease 
by giving Lessor written notice of Lessee's election to do so at any time prior 
to the commencement or completion, respectively, or such repair or restoration. 
In such event this lease shall terminate as of the date of such notice.

restoration and repair, including but not limited to the approval and/or 
execution of plans and specifications required.

theretofore been applied by Lessor.

    9.7  Waiver. Lessor and Lessee waive the provisions of any statute which 
relate to termination of leases when leased property is destroyed and agree that
such event shall be governed by the terms of this Lease.

paragraph 10.3, applicable to the Office Building Project subject to 
reimbursement by Lessee of Lessee's Share of such taxes in accordance with the 
provisions of paragraph 4.2, except as otherwise provided in paragraph 10.2.

increase in real property tax specified in the tax assessor's records and work 
sheets as being caused by additional improvements placed upon the Office 
Building Project by other lessees or by Lessor for the exclusive enjoyment of 
any other lessee. Lessee shall, however, pay to Lessor at the time that 
Operating Expenses are payable under paragraph 4.2(c) the entirety of any 
increase in real property tax if assessed solely by reason of additional 
improvements placed upon the Premises by Lessee or at Lessee's request.

    10.3 Definition of "Real Property Tax". As used herein, the term "real 
property tax" shall include any form of real estate tax or assessment, general, 
special, ordinary or extraordinary, and any license fee, commercial rental tax, 
improvement bond or bonds, levy or tax (other than inheritance, personal income 
or estate taxes) imposed on the Office Building Project or any portion thereof 
by any authority having the direct or indirect power to tax, including any city,
county, state or federal government, or any school, agricultural, sanitary, 
fire, street, drainage or other improvement district thereof, as against any 
legal or equitable interest of Lessor in the Office Building Project or in any
portion thereof, as against Lessor's right to rent or other income therefrom,
and as against Lessor's business of leasing the Office Building Project. The
term "real property tax" shall also include any tax, fee, levy, assessment or
charge (i) in substitution of, partially or totally, any tax, fee, levy
assessment or charge hereinabove included within the definition of "real
property tax", or (ii) the nature of which was hereinbefore included within the
definition of "real property tax," or (iii) which is imposed for a service or
right not charged prior to June 1, 1978, or, if previously charged, has been
increased since June 1, 1978, or (iv) which is imposed as a result of a change
in ownership, as defined by applicable local statutes for property tax purposes,
of the Office Building Project or which is added to a tax or charge hereinbefore
included within the definition of real property tax by reason of such change of
ownership, or (v) which is imposed by reason of this transaction, any
modifications or changes hereto, or any transfers hereof.

    10.4 Joint Assessment. If the improvements or property, the taxes for which 
are to be paid separately by Lessee under paragraph 10.2 or 10.5 are not
separately assessed, Lessee's portion of that tax shall be equitably determined
by Lessor from the respective valuations assigned in the assessor's work sheets
or such other information (which may include the cost of construction) 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.

         (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.

    11.1 Services Provided by Lessor. Lessor shall provide heating, ventilation,
air conditioning, elevator, and janitorial service as reasonably required, 
reasonable amounts of electricity for normal lighting and office machines, water
for reasonable and normal drinking and lavatory use, and replacement light bulbs
and/or fluorescent tubes and ballasts for standard overhead fixtures.

    11.2 Services Exclusive to Lessee. Lessee shall pay for all water, gas, 
heat, light, power, telephone and other utilities and services specially or 
exclusively supplied and/or metered exclusively to the Premises or to Lessee, 
together with any taxes thereon. If any such services are not separately metered
to the Premises, Lessee shall pay at Lessor's option, either Lessee's Share or a
reasonable proportion to be determined by Lessor of all charges jointly metered 
with other premises in the Building.

    11.3 Hours of Service. Said services and utilities shall be provided during 
generally accepted business days and hours or such other days or hours as may 
hereafter be set forth. Utilities and services required at other times shall be 
subject to advance request and reimbursement by Lessee to Lessor of the cost 
thereof.

     11.4  Excess Usage by Lessee.  Lessee shall not make connection to the 
utilities except by or through existing outlets and shall not install or use 
machinery or equipment in or about the Premises that uses excess water, lighting
or power, or suffer or permit any act that causes extra burden upon the 
utilities or services, including but not limited to security services, over 
standard office usage for the Office Building Project.  Lessor shall require 
Lessee to reimburse Lessor for any excess expenses or costs that may arise out 
of a breach of this subparagraph by Lessee.  Lessor may, in its sole discretion,
install at Lessee's expense supplemental equipment and/or separate metering 
applicable to Lessee's excess usage or loading.

     11.5  Interruptions.  There shall be no abatement of rent and Lessor shall 
not be liable in any respect whatsoever for the inadequacy, stoppage, 
interruption or discontinuance of any utility or service due to riot, strike, 
labor dispute, breakdown, accident, repair or other cause beyond Lessor's 
reasonable control or in cooperation with governmental request or directions.

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 unreasonably 
withhold or delay, 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 material default and breach of this Lease without the need for 
notice to Lessee under paragraph 13.1.  "Transfer" within the meaning of this 
paragraph 12 shall included the transfer or transfers aggregating: (a) if Lessee
is a corporation, more than twenty-five percent (25%) of the voting stock of 
such corporation, or (b) if Lessee is a partnership, more than twenty-five 
percent (25%) of the profit and loss participation in such partnership.

     12.2  Lessee Affiliate.  Notwithstanding the provisions of paragraph 12.1 
hereof, Lessee may assign or sublet the Premises, or any portion thereof, 
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, (a) said assignee shall
assume, in full, the obligations of Lessee under this Lease and (b) Lessor shall
be given written notice of such assignment and assumption.  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 Applicable to Assignment and Subletting.

           (a)   Regardless of Lessor's consent, no assignment or subletting 
shall release Lessee of Lessee's obligations hereunder or alter the primary 
liability of Lessee to pay the rent and other sums due Lessor hereunder 
including Lessee's Share of Operating Expense increase, and to perform all other
obligations to be performed by Lessee hereunder.

           (b)   Lessor may accept rent from any person other than Lessee 
pending approval or disapproval of such assignment.

           (c)   Neither a delay in the approval or disapproval of such 
assignment or subletting, 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.

           (d)   If Lessee's obligations under this Lease have been guaranteed 
by third parties, then an assignment or sublease, and Lessor's consent thereto, 
shall not be effective unless said guarantors give their written consent to such
sublease and the terms thereof.

           (e)   The consent by Lessor to any assignment or subletting shall not
constitute a consent to any subsequent assignment or subletting by Lessee or to 
any subsequent or successive 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 under this Lease 
or said sublease; however, such persons shall not be responsible to the extent 
any such amendment or modification enlarges or increases the obligations of the 
Lessee or sublessee under this Lease or such sublease.

           (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)   Lessor's written consent to any assignment or subletting of the
Premises by Lessee shall not constitute an acknowledgement 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.

           (h)   The discovery of the fact that any financial statement relied 
upon by Lessor in giving its consent to an assignment or subletting was 
materially false shall, at Lessor's election, render Lessor's said consent null 
and void.

     12.4  Additional 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 deemed 
included in all subleases under this Lease whether or not expressly incorporated
therein:

           (a)   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 sublessee 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 sublease 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, which shall not be unreasonably 
withheld or delayed.

           (b)   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 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.

           (c)   No sublessee shall further assign or sublet all or any part of 
the Premises without Lessor's prior written consent.

           (d)   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 three (3) 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  Lessor's Expenses.  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 costs and expenses incurred in 
connection therewith, including attorneys', architects', engineers' or other 
consultants' fees.

     12.6  Conditions to Consent.  Lessor reserves the right to condition any 
approval to assign or sublet upon Lessor's determination that (a) the proposed 
assignee or sublessee shall conduct a business on the Premises of a quality 
substantially equal to that of Lessee and consistent with the general character 
of the other occupants of the Office Building Project and not in violation of 
any exclusives or rights then held by other tenants, and (b) the proposed 
assignee or sublessee be at least as financially responsible as Lessee was 
expected to be at the time of the execution of this Lease or of such assignment 
or subletting, whichever is greater, as is necessary to satisfy Lessor's then 
current underwriting requirements for a subtenant or assignee or Lessor's 
internal requirements.

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 vacation or abandonment of the Premises by Lessee.  
Vacation of the Premises shall include the failure to occupy the Premises for a 
continuous period of sixty (60) days or more, whether or not the rent is paid.

           (b)   The breach by Lessee of any of the covenants, conditions or 
provisions of paragraphs 7.3(a),(b) or (d)(alterations), 12.1(assignment or 
subletting), 13.1(a)(vacation or abandonment), 13.1(e)(insolvency), 13.1(f) 
(false statement), 16(a)(estoppel certificate), 30(b)(subordination), 
33(auctions), or 41.1(easements), all of which are hereby deemed to be 
material, non-curable defaults without the necessity of any notice by Lessor 
to Lessee thereof.

           (c)   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.

<PAGE>
 
     (d) The failure by Lessee to observe or perform any of the covenants,
conditions or provisions of this Lease to be observed or performed by Lessee
other than those referenced in subparagraphs (b) and (c), 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 Lessee 
commenced such cure within said thirty (30) day period and thereafter 
diligently pursues 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. 

     (e) (i) The making by Lessee of any general arrangement or general 
assignment for the benefit of creditors; (ii) Lessee becoming a "debtor" as
defined in 11 U.S.C. (Section)101 or any successor statute 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 provison of this paragraph 13.1(e) is contrary to
any applicable law, such provision shall be of no force or effect.

     (f) The discovery by Lessor that any financial statement given to Lessor
by Lessee, or its successor in interest or by any guarantor of Lessee's 
obligation hereunder, was materially false. 

   13.1 Default. 
   
        (g)  A default under the Primary Lease. 

   In addition, the Primary Lease is hereby amended to provide that a default
   hereunder shall be a default under the Primary Lease.
  
   13.2 Remedies. In the event of any material default or breach of this Lease 
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's 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 attorneys' 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 new or hereafter available to Lessor under 
the laws or judicial decision 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.

   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 30-day period and thereafter diligently
pursues 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 Expense Increase 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 Office Building Project. Accordingly, if any installment of 
Base Rent, Operating Expense increase, 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.

14. Condemnation. If the Premises or any portion thereof or the Office Building 
Project 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; provided that if so
much of the Premises or the Office Building Project are taken by such 
condemnation as would substantially and adversely affect the operation and 
profitability of Lessee's  business conducted from the Premises, Lessee shall 
have the option, to be exercised only in writing within (30) days after Lessor 
shall have given Lessee written notice of such taking (or in the absence of such
notice, within (30) days after the condemning authority shall have taken
possession), to 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 and Lessee's Share of 
Operating Expense increase shall be reduced in the proportion that the floor 
area of the Premises taken bears to the total floor area of the Premises. Common
Areas taken shall be excluded from the Common Areas usable by Lessee and no 
reduction of rent shall occur with respect thereto or by reason thereof, Lessor 
shall have the option in its sole discretion to terminate this Lease as of the 
taking of possession by the condemning authority, by giving written notice to 
Lessee of such election within thirty (30) days after receipt of notice of a 
taking by condemnation of any part of the Premises or the Office Building 
Project. Any award for the taking of all or any part of the Premises or the 
Office Building Project 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 any separate award for loss of or 
damage to Lessee's trade fixtures, removable personal property and unamortized 
tenant improvements that have been paid for by Lessee. For that purpose the cost
of such improvements shall be amortized over the original term of this Lease 
excluding any options. 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) The brokers involved in this transaction are THE SEELEY COMPANY and CB 
                                                     -------------------------
COMMERCIAL INC. as "listing broker" and THE KAUFMAN GROUP as "cooperating 
- ---------------                         ----------------
broker," licensed real estate broker(s). A "cooperating broker" is defined as 
any broker other than the listing broker entitled to a share of any commission 
arising under this Lease. Upon execution of this Lease by both parties, Lessor 
shall pay to said brokers jointly, or in such separate shares as they may 
mutually designate in writing, 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 $  (per separate 
                                                        ----------------
agreement) , for brokerage services rendered by said broker(s) to Lessor in this
- -----------
transaction.

    (b) Lessor further agrees that (i) 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 (ii) 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 (iii) if Lessee remains in possession of
the Premises after the expiration of the term of this Lease after having failed
to exercise an Option, or (iv) 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 any adjacent property in which Lessor has an interest, or (v) if the Base
Rent is increased, whether by agreement or operation of an escalation clause
contained herein, then as to any of said transactions or rent increases, 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. Said fee shall be paid at the
time such increased rental is determined.

    (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 interest 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. Each listing and cooperating broker
shall be a third party beneficiary of the provisions of this paragraph 15 to the
extent of their interest in any commission arising under this Lease and may
enforce that right directly against Lessor; provided, however, that all brokers
having a right to any part of such total commission shall be a necessary party
to any suit with respect thereto.

    (d) Lessee and Lessor each represent and warrant to the other that neither 
has had any dealings with any person, firm, broker or finder (other than the 
person(s), if any, whose names are set forth in paragraph 15(a), above) in 
connection with the negotiation of this Lease and/or  the consummation of the 
transaction contemplated hereby, and no other broker or other person, firm or 
entity is entitled to any commission or finder's fee in connection with said 
transaction and Lessee and Lessor do each hereby indemnify and hold the other 
harmless from and against any costs, expenses, attorneys' fees or liability for 
compensation or charges which may be claimed by any such unnamed broker, finder 
or other similar party by reason of any dealings or actions of the indemnifying 
party.

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 that this 
Lease, as so modified, is in full force and effect) and the date

<PAGE>
 
to which the rent and other charges are paid in advance, if any, and (ii) 
acknowledging that there are not, to the responding party's knowledge, any 
uncured defaults on the part of the requesting party, or specifying such 
defaults if any are claimed. Any such statement may be conclusively relied upon 
by any prospective purchaser or encumbrancer of the Office Building Project or 
of the business of Lessee.

  (b) At the requesting party's option, the failure to deliver such statement 
within such time shall be a material default of this Lease by the party who is
to respond, without any further notice to such party, or it shall be 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 in
advance.

  (c) If Lessor desires to finance, refinance, or sell the Office Building 
Project, or 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 be used only for the purposes herein set forth.

17.Lessor's Liability. The term "Lessor" as used herein shall mean only the
owner or owners, at the time in question, of the fee title or a lessee's
interest in a ground lease of the Office Building Project, 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 by
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 or judgments 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.

20.Time of Essence. Time is of the essence with respect to the obligations to be
performed under this Lease.

21.Additional Rent. All monetary obligations of Lessee to Lessor under the terms
of this Lease, including but not limited to Lessee's Share of Operating Expense
increase and any other expenses payable by Lessee hereunder shall be deemed to
be rent.

22.Incorporation of Prior Agreements; Amendments. This Lease contains all
agreements of the parties with respect to any matter mentioned herein. No prior
or contemporaneous agreement or understanding pertaining to any such matter
shall be effective. This Lease may be modified in writing only, signed by the
parties in interest at the time of the modification. Except as otherwise stated
in this Lease, Lessee hereby acknowledges that neither the real estate broker
listed in paragraph 15 hereof nor any cooperating broker on this transaction nor
the Lessor or any employee or agents of any of said persons has made any oral or
written warranties or representations to Lessee relative to the condition or use
by Lessee of the Premises or the Office Building Project and Lessee acknowledges
that Lessee assumes all responsibility regarding the Occupational Safety Health
Act, the legal use and adaptability of the Premises and the compliance thereof
with all applicable laws and regulations in effect during the term of this
Lease.

23.Notices. Any notice required or permitted to be given hereunder shall be 
in writing and may be given by personal delivery or by certified or registered
mail, and shall be deemed sufficiently given if delivered or addressed to Lessee
or to Lessor at the address noted below or adjacent to the signature of the
respective parties, as the case may be. Mailed notices shall be deemed given
upon actual receipt at the address required, or forty-eight hours following
deposit in the mail, postage prepaid, whichever first occurs. Either party may
by notice to the other specify a different address for notice purposes except
that upon Lessee's taking possession of the Premises, the Premises shall
constitute Lessee's address for notice purposes. A copy of all notices required
or permitted to be given to Lessor hereunder shall be concurrently transmitted
to such party or parties at such addresses as Lessor may from time to time
hereafter designate by notice to Lessee.

24.Waivers. No waiver by Lessor of any provision hereof shall be deemed a waiver
of any other provision hereof or of any subsequent breach by Lessee of the same
or any other provision. Lessor's consent to, or approval of, any act shall not
be deemed to render unnecessary the obtaining of Lessor's consent to or approval
of any subsequent act by Lessee. The acceptance of rent hereunder by Lessor
shall not be a waiver of any preceding breach by Lessee of any provision hereof,
other than the failure of Lessee to pay the particular rent so accepted,
regardless of Lessor's knowledge of such preceding breach at the time of
acceptance of such rent.

25.Recording. Either Lessor or Lessee shall, upon request of the other, 
execute, acknowledge and deliver to the other a "short form" memorandum of this 
Lease for recording purposes.

26.Holding Over. If Lessee, with Lessor's consent, remains in possession of the 
Premises or any part thereof after the expiration of the term hereof, such 
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease pertaining to the obligations of Lessee, except that the rent payable
shall be two hundred percent (200%) of the rent payable immediately preceding
the termination date of this Lease, and all Options, if any, granted under the
terms of this Lease shall be deemed terminated and be of no further effect
during said month to month tenancy.

27.Cumulative Remedies. No remedy or election hereunder shall be deemed 
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28.Covenants and Conditions. Each provision of this Lease performable by Lessee 
shall be deemed both a covenant and a condition.

29.Binding Effect; Choice of Law. Subject to any provisions hereof restricting 
assignment or subletting by Lessee and subject to the provisions of paragraph 
17, this Lease shall bind the parties, their personal representatives, 
successors and assigns. This Lease shall be governed by the laws of the State 
where the Office Building Project is located and any litigation concerning this 
Lease between the parties hereto shall be initiated in the county in which the 
Office Building Project is located.

30.Subordination.
   (a) This Lease, and any Option or right of first refusal granted hereby, at
Lessor's option, shall be subordinate to any ground lease, mortgage, deed of
trust, or any other hypothecation or security now or hereafter placed upon the
Office Building Project 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.

   (b) Lessee agrees to execute any documents required to effectuate 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 attorney-in-fact and
in Lessee's name, place and stead, to execute such documents in accordance with
this paragraph 30(b).

31.Attorneys' Fees.

   31.1 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, trial or appeal thereon, shall be entitled to his reasonable attorneys'
fees to be paid by the losing party as fixed by the court in the same or a
separate suit, and whether or not such action is pursued to decision or
judgment. The provisions of this paragraph shall inure to the benefit of the
broker named herein who seeks to enforce a right hereunder.

   31.2 The attorneys' fee award shall not be computed in accordance with any 
court fee schedule, but shall be such as to fully reimburse all attorneys' fees 
reasonably incurred in good faith.

   31.3 Lessor shall be entitled to reasonable attorneys' fees and all other
costs and expenses incurred in the preparation and service of notice of default
and consultations in connection therewith, whether or not a legal transaction is
subsequently commenced in connection with such default.

32.Lessor's Access.
   
   32.1 Lessor and Lessor's agents shall have the right to enter the Premises at
reasonable times for the purpose of inspecting the same, performing any services
required of Lessor, showing the same to prospective purchasers, lenders, or
lessees, taking such safety measures, erecting such scaffolding or other
necessary structures, making such alterations, repairs, improvements or
additions to the Premises or to the Office Building Project as Lessor may
reasonably deem necessary or desirable and the erecting, using and maintaining
of utilities, services, pipes and conduits through the Premises and/or other
premises as long as there is no material adverse effect to Lessee's use of the
Premises, 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.

   32.2 All activities of Lessor pursuant to this paragraph shall be without 
abatement of rent, nor shall Lessor have any liability to Lessee for the same.

   32.3 Lessor shall have the right to retain keys to the Premises and to unlock
all doors in or upon the Premises other than to files, vaults and safes, and in 
the case of emergency to enter the Premises by any reasonably appropriate means,
and any such entry shall not be deemed a forceable or unlawful entry or detainer
of the Premises or an eviction. Lessee waives any charges for damages or 
injuries or interference with Lessee's property or business in connection 
therewith.

33. Auctions. Lessee shall not conduct, nor permit to be conducted, either 
voluntarily or involuntarily, any auction upon the Premises or the Common Areas 
without first having obtained Lessor's prior written consent. Notwithstanding 
anything to the contrary in this Lease, Lessor shall not be obligated to 
exercise any standard of reasonableness in determining whether to grant such 
consent. The holding of any auction on the Premises or Common Areas in violation
of this paragraph shall constitute a material default of this Lease.

34. Signs. Lessee shall not place any sign upon the Premises or the Office 
Building Project without Lessor's prior written consent. Under no circumstances 
shall Lessee place a sign on any roof of the Office Building Project.

35. Merger. The voluntary or other surrender of this Lease by Lessee, or a 
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 paragraphs 33 (auctions) and 34 (signs) 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.

37. Guarantor. In the event that there is a guarantor of this Lease, said 
guarantor shall have the same obligations as Lessee under this Lease.

38. Quiet Possession. Upon Lessee paying the rent for the Premises and observing
and performing all of the covenants, conditions and provisions on Lessee's part 
to be observed and performed hereunder, Lessee shall have quiet possession of 
the Premises for the entire term hereof subject to all of the 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 execution is binding upon
all parties holding an ownership interest in the Office Building Project.

39. Options.

    39.1 Definition. As used in this paragraph the word "Option" has the 
following meaning: (1) the right or option to extend the term of this Lease or 
to renew this Lease or to extend or renew any lease that Lessee has on other 
property of Lessor; (2) the option of right of first refusal to lease the 
Premises or the right of first offer to lease the Premises or the right of first
refusal to lease other space within the Office Building Project or other 
property of Lessor or the right of first offer to lease other space within the 
Office Building Project or other property of Lessor; (3) the right or option to 
purchase the Premises or the Office Building Project, or the right of first 
refusal to purchase the Premises or the Office Building Project or the right of 
first offer to purchase the Premises or the Office Building Project, or the 
right or option to purchase other property of Lessor, or the right of first 
refusal to purchase other property of Lessor or the right of first offer to 
purchase other property of Lessor.

    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(c) or 13.1(d) and continuing until the noncompliance alleged in 
said notice of default is cured, or (ii) during the period of time commencing on
the day 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) in the event that Lessor has given to Lessee three 
or more notices of default under paragraph 13.1(c), or paragraph 13.1(d), 
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, (iv) if Lessee has committed any non-curable breach, including without 
limitation those described in paragraph 13.1(b), or is otherwise in default of 
any of the terms, covenants or conditions of this Lease.

         (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).

40. Security Measures--Lessor's Reservations.

    40.1 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 Office Building Project. 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 security protection for the Office Building Project 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).

    40.2 Lessor shall have the following rights:

         (a) To change the name, address or title of the Office Building Project
or building in which the Premises are located upon not less than 90 days prior
written notice;

         (b) To, at Lessee's expense, provide and install Building standard 
graphics on the door of the Premises and such portions of the Common Areas as 
Lessor shall reasonably deem appropriate;

         (c) To permit any lessee the exclusive right to conduct any business as
long as such exclusive does not conflict with any rights expressly given herein;

         (d) To place such signs, notices or displays as Lessor reasonably deems
necessary or advisable upon the roof, exterior of the buildings or the Office
Building Project or on pole signs in the Common Areas;

    40.3 Lessee shall not:
 
         (a) Use a representation (photographic or otherwise) of the Building or
the Office Building Project or their name(s) in connection with Lessee's
business;

         (b) Suffer or permit anyone, except in emergency, to go upon the roof
of the Building.

    41.1 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.

    41.2 The obstruction of Lessee's view, air, or light by any structure
erected in the vicinity of the Building, whether by Lessor or third parties,
shall in no way affect this Lease or impose any liability upon Lessor.

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 make 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.

preliminary plans and specifications for the completion of the Improvements, 
which plans and specifications shall itemize the work to be done by each party, 
including a cost estimate of any work required of Lessor in excess of Lessor's 
Standard Improvements. Lessee shall approve said preliminary plans and 
specifications and preliminary cost estimate or specify with particularity its 
objection thereto within ___________ days following receipt thereof. Failure to 
so approve or disapprove within said period of time shall constitute approval 
thereof. If Lessee shall reject said preliminary plans and specifications either
partially or totally, and they cannot in good faith be modified within ten (10) 
days after such rejection to be acceptable to Lessor and Lessee, this Lease 
shall terminate and neither party shall thereafter be obligated to the other 
party for any reason whatsoever having to do with this Lease, except that Lessee
shall be refunded any security deposit or prepaid rent. The plans and 
specifications, when approved by Lessee, shall supersede any prior agreement 
concerning the Improvements.

15. Construction

    If Lessor's cost of constructing the Improvements to the Premises exceeds 
the cost of Lessor's Standard Improvements, Lessee shall pay to Lessor in cash 
before the commencement of such construction a sum equal to such excess.

    If the final plans and specifications are approved by Lessor and Lessee, and
Lessee pays Lessor for such excess, then Lessor shall, at its sole cost and 
expense, construct the Improvements in accordance with said approved final plans
and specifications and all applicable rules, regulations, laws or ordinances.

16. Completion. 

    16.1 Lessor shall obtain a building permit to construct the Improvements as 
soon as possible.

reasonably possible after the obtaining of necessary building permits.

    16.4 Lessor shall use its best efforts to achieve Completion of the 
Improvements on or before the Commencement Date set forth in paragraph 1.5 of 
the Basic Lease Provisions or within one hundred eighty (180) days after Lessor 
obtains the building permit from the applicable building department, whichever 
is later.

    16.5 In the event that the Improvements or any portion thereof have not 
reached Completion by the Commencement Date, this Lease shall not be invalid, 
but rather Lessor shall complete the same as soon thereafter as is possible and 
Lessor shall not be liable to Lessee for damages in any respect whatsoever.

    16.6 If Lessor shall be delayed at any time in the progress of the 
construction of the Improvements or any portion thereof by extra work, changes 
in construction ordered by Lessee, or by strikes, lockouts, fire, delay in 
transportation, unavoidable casualties, rain or weather conditions, governmental
procedures or delay, or by any other cause beyond Lessor's control, then the 
Commencement Date established in paragraph 1.5 of the Lease shall be extended by
the period of such delay.

17. Term

    Upon Completion of the Improvements as defined in paragraph 16.3, above, 
Lessor and Lessee shall execute an amendment to the Lease setting forth the date
of Tender of Possession as defined in paragraph 3.2.1 of the Lease or of actual 
taking of possession, whichever first occurs, as the Commencement Date of this
Lease.

18. Work Done by Lessee

consent and in conformity with a valid building permit and all applicable rules,
regulations, laws and ordinances, and be done in a good and workmanlike manner

and only by contractors approved by Lessor, it being understood that all 
plumbing, mechanical, electrical wiring and ceiling work are to be done only by 
contractors designated by Lessor.

(10) days before said date. Lessee shall thereafter have the right to enter the 
Premises to commence construction of any Improvements Lessee is to construct and
to equip and fixturize the Premises, as long as such entry does not interfere 
with Lessor's work. Lessee shall take possession of the Premises upon the tender
thereof as provided in paragraph 3.2.1 of the Lease to which this Work Letter is
attached. Any entry by Lessee of the Premises under this paragraph shall be 
under all of the terms and provisions of the Lease to which this Work Letter is

provisions of this Section 12.1 shall not prohibit Lessee from entering into 
licenses with customers or agents of customers of Lessee which require space for
the purpose of testing or inspecting products produced by Lessee, provided such 
license is temporal in nature and does not constitute a grant of exclusive space
within the Premises by Lessee.

32.  Lessor's Access.  Lessor and Lessor's agents shall provide Lessee with 
twenty-four (24) hours' notice prior to entry of the Premises, except in the 
event of an emergency which shall require no notice. Such entry by Lessor and

necessary. During any such entry, except emergency entries, Lessor and Lessor's 
agents shall at all times be accompanied by Lessee or Lessee's agent. In the

accompanied by a representative of Lessee.

Paragraph 1.2 and the calculation of rent (Paragraph 1.6), security deposits 
(Paragraph 1.9) and Lessee's share of operating expenses (Paragraph 1.10) shall 
be computed based upon $1.06 per rentable square foot pursuant to the final 
approved space plan. Rentable square footage shall be computed based upon the 
usable square feet multiplied by 1.15% (15% load factor). The vehicle parking 
spaces allocated to Lessee pursuant to Paragraph 2.2 shall be based upon 1,000 
square feet of usable area. In the event a discrepancy is determined regarding 
the square footage of the Premises, the foregoing amounts may be adjusted, 
provided that in event shall either party be entitled to any retroactive 
adjustment whether for operating expenses, rent or parking.

50.  Right of First Notice of Lease - Primary Lease.  Section 50 of the Primary 
Lease regarding the availability of space on the second floor is hereby deleted 
in its entirety.

51.  Option to Renew Lease.  Lessee is given the option to extend the term on 
all the provisions contained in this lease, except for minimum monthly rent, for
a five (5) year period ("Extended Term") following expiration of the initial 
term, by giving notice of exercise of the option ("Option Notice") to Lessor at 
least six (6) months, but not more than one (1) year before the expiration of 
the term. Provided that, if Lessee is in default on the date of giving the 
Option Notice, the Option Notice shall be totally ineffective, or if Lessee is 
in default on the date the Extended Term is to commence, the Extended Term shall
not commence and this lease shall expire at the end of the initial term.

           The parties shall have thirty (30) days after Lessor receives the
     Option Notice in which to agree on Base Rent during the Extended Term. If
     the parties agree on the Base Rent for the Extended Term during that
     period, they shall immediately execute an amendment to this stating the
     Base Rent.

           If the parties are unable to agree on the Base Rent for the Extended 
Term within that period, then within ten (10) days after the expiration of that 
period each party, at its cost and by giving notice to the other party, shall 
appoint a real estate appraiser with at least 5 years' full-time commercial 
appraisal experience in the area in which the premises are located to appraise 
and set the Base Rent for the Extended Term based upon ninety-five percent (95%)
of the fair market rental for the Premises based upon the prevailing market 
rates for similar space in similar buildings. If a

                                      -2-
<PAGE>
 
     party does not appoint an appraiser within ten (10) days after the other
     party has given notice of the name of its appraiser, the single appraiser
     appointed shall be the sole appraiser and shall set the Base Rent for the
     Extended Term. If the two appraisers are appointed by the parties as stated
     in this paragraph, they shall meet promptly and attempt to set the Base
     Rent for the Extended Term. If they are unable to agree within thirty (30)
     days after the second appraiser has been appointed, they shall attempt to
     elect a third appraiser meeting the qualifications stated in this paragraph
     within ten (10) days after the last day the two appraisers are given to set
     the Base Rent. If they are unable to agree on the third appraiser, either
     of the parties to this lease by giving ten (10) days' notice to the other
     party can file a petition with the American Arbitration Association solely
     for the purpose of selecting a third appraiser who meets the qualifications
     stated in this paragraph. Each party shall bear half the cost of the
     American Arbitration Association appointing the third appraiser and of
     paying the third appraiser's fee. The third appraiser, however selected,
     shall be a person who has not previously acted in any capacity for either
     party.

          Within thirty (30) days after the selection of the third appraiser, a 
     majority of the appraisers shall set the Base Rent for the Extended Term.
     If a majority of the appraisers are unable to set the Base Rent within the
     stipulated period of time, the three appraisals shall be added together
     and their total divided by three; the resulting quotient shall be the Base
     Rent for the premises during the Extended term. If, however, the low
     appraisal and/or the high appraisal are more than ten percent (10%) lower
     and/or higher than the middle appraisal, the low appraisal and/or the high
     appraisal shall be disregarded. If only one appraisal is disregarded, the
     remaining two appraisals shall be added together and their total divided by
     two; the resulting quotient shall be the Base Rent for the premises during
     the Extended Term. If both the low appraisal and the high appraisal are
     disregarded as stated in this paragraph, the middle appraisal shall be the
     Base Rent for the premises during the Extended Term.

          After the Base Rent for the Extended Term has been set, the appraisers
     shall immediately notify the parties.

         Lessee shall have no other right to extend the term beyond the Extended
     Term. In no event shall Lessee have the right to exercise the right to
     extend hereunder unless the right to extend under the Primary Lease is
     exercised. Furthermore, in no event shall Lessee have the right to exercise
     its right to extend the primary Lease unless the term of this Lease is
     extended hereunder.

52.  Increase in Property Taxes During the First Three (3) Years of the Lease
Term.  During the first three (3) year of the initial lease term, Lessee shall 
not be responsible for any increases in property taxes resulting from the 
reassessment of the property caused by a sale of the property by Lessor 
("Proposition 13").

53.  Signage.  Lessee shall have the right to install its sign on one (1) 
position of the shared monument sign at the parking lot entrance to the 
property. All signage is subject to City of El Segundo approval.

55.  Non-Disturbance Agreements. Lessor shall use commercially reasonable
efforts to obtain promptly following the execution of the Lease, 
non-disturbance, subordination and attornment agreements from Lessor's lender in
form reasonable satisfactory to Lessor's lender, Lessor and Lessee. Lessor and
Lessee shall use reasonable and diligent efforts to satisfy the foregoing
obligation.

56.  Lessee's Construction Work.  Lessee acknowledges that Lessor is completing 
a refurbishment of the Building simultaneously with Lessee's completing its 
improvements. Lessee shall complete the 

                                      -3-

improvements to the Premises in conformance with the Floor Plan attached to the 
Lease as Exhibit "A". Lessor and Lessee shall use reasonable and diligent 
         ----------
efforts to promptly complete their respective improvements. All such 
improvements shall be substantially completed on or before November 1, 1996. 

57.  Coterminous Term. This Lease shall be coterminous with the Primary Lease 
and in the event the Primary Lease terminates for any reason whatsoever, this 
Lease shall terminate. Similarly, in the event this Lease terminates for any 
reason whatsoever, the Primary Lease shall terminate.

               --------------                                               
time to time.

          (n) "Stock" - Authorized and issued or unissued shares of Class A
               -----                                                       
Common Stock of the Company.

          (o) "Stock Award" - A Grant made under the Plan in stock or
               -----------                                           
denominated in units of stock for which the Participant is not obligated to pay
additional consideration.

     3.  ADMINISTRATION

          The Plan shall be administered by the Board, provided however, that
the Board may delegate such administration to the Committee.  Subject to the
provisions of the Plan, the Board and/or the Committee shall have authority to
(a) grant, in its discretion, Incentive Stock Options in accordance with Section
422 of the Code, or Nonstatutory Options, Stock Awards or Restricted Stock
Purchase Offers; (b) determine in good faith the fair market value of the Stock
covered by any Grant; (c) determine which eligible persons shall receive Grants
and the  number of shares, restrictions, terms and conditions to be included in
such Grants; (d) construe and interpret the Plan; (e) promulgate, amend and
rescind rules and regulations relating to its administration, and correct
defects, omissions and inconsistencies in the Plan or any Grant; (f) consistent
with the Plan and with the consent of the Participant, as appropriate, amend any
outstanding Grant or amend the exercise date or dates thereof; (g) determine the
duration and purpose of leaves of absence which may be granted to Participants
without constituting termination of their employment for the purpose of the Plan
or any Grant; and (h) make all other determinations necessary or advisable for
the Plan's administration.  The interpretation and construction by the Board of
any provisions of the Plan or selection of Participants shall be conclusive and
final.  No member of the Board or the Committee shall be 

                                      -2-
<PAGE>
 
liable for any action or determination made in good faith with respect to the
Plan or any Grant made thereunder.

     4.  ELIGIBILITY

          (a) General:  The persons who shall be eligible to receive Grants
              -------                                                      
shall be directors, officers, employees or consultants to the Company.  The term
consultant shall mean any person, other than an employee, who is engaged by the
Company to render services and is compensated for such services.  An Optionee
may hold more than one Option.  Any issuance of a Grant to an officer or
director of the Company subsequent to the first registration of any of the
securities of the Company under the Exchange Act shall comply with the
requirements of Rule 16b-3.

          (b) Incentive Stock Options:  Incentive Stock Options may only be
              -----------------------                                      
issued to employees of the Company.  Incentive Stock Options may be granted to
officers, whether or not they are directors, provided they are also employees of
the Company.  Payment of a director's fee shall not be sufficient to constitute
employment by the Company.

          The Company shall not grant an Incentive Stock Option under the Plan
to any employee if such Grant would result in such employee holding the right to
exercise for the first time in any one calendar year, under all Incentive Stock
Options granted under the Plan or any other plan maintained by the Company, with
respect to shares of Stock having an aggregate fair market value, determined as
of the date of the Option is granted, in excess of $100,000.  Should it be
determined that an Incentive Stock Option granted under the Plan exceeds such
maximum for any reason other than a failure in good faith to value the Stock
subject to such option, the excess portion of such option shall be considered a
Nonstatutory Option.  To the extent the employee holds two (2) or more such
Options which become exercisable for the first time in the same calendar year,
the foregoing limitation on the exercisability of such Option as Incentive Stock
Options under the Federal tax laws shall be applied on the basis of the order in
which such Options are granted.  If, for any reason, an entire Option does not
qualify as an Incentive Stock Option by reason of exceeding such maximum, such
Option shall be considered a Nonstatutory Option.

          (c) Nonstatutory Option:  The provisions of the foregoing Section 4(b)
              -------------------                                               
shall not apply to any Option designated as a "Nonstatutory Option" or which
sets forth the intention of the parties that the Option be a Nonstatutory
Option.

          (d) Stock Awards and Restricted Stock Purchase Offers:  The provisions
              -------------------------------------------------                 
of this Section 4 shall not apply to any Stock Award or Restricted Stock
Purchase Offer under the Plan.

                                      -3-
<PAGE>
 
     5.  STOCK

          (a) Authorized Stock:  Stock subject to Grants may be either unissued
              ----------------                                                 
or reacquired Stock.

          (b) Number of Shares:  Subject to adjustment as provided in Section
              ----------------                                               
6(i) of the Plan, the total number of shares of Stock which may be purchased or
granted directly by Options, Stock Awards or Restricted Stock Purchase Offers,
or purchased indirectly through exercise of Options granted under the Plan shall
not exceed 800,000.  If any Grant shall for any reason terminate or expire, any
shares allocated thereto but remaining unpurchased upon such expiration or
termination shall again be available for Grants with respect thereto under the
Plan as though no Grant had previously occurred with respect to such shares.
Any shares of Stock issued pursuant to a Grant and repurchased pursuant to the
terms thereof shall be available for future Grants as though not previously
covered by a Grant.

          (c) Reservation of Shares:  The Company shall reserve and keep
              ---------------------                                     
available at all times during the term of the Plan such number of shares as
shall be sufficient to satisfy the requirements of the Plan.  If, after
reasonable efforts, which efforts shall not include the registration of the Plan
or Grants under the Securities Act, the Company is unable to obtain authority
from any applicable regulatory body, which authorization is deemed necessary by
legal counsel for the Company for the lawful issuance of shares hereunder, the
Company shall be relieved of any liability with respect to its failure to issue
and sell the shares for which such requisite authority was so deemed necessary
unless and until such authority is obtained.

          (d)  Application of Funds:  The proceeds received by the Company from 
               --------------------
the sale of common Stock pursuant to the exercise of Options or rights under
Stock Purchase Agreements will be used for general corporate purposes.

          (e)  No Obligation to Exercise:  The issuance of a Grant shall impose 
               -------------------------
no obligation upon the Participant to exercise any rights under such Grant.

     6.  TERMS AND CONDITIONS OF OPTIONS

          Options granted hereunder shall be evidenced by agreements between the
Company and the respective Optionees, in such form and substance as the Board or
Committee shall from time to time approve.  The form of Incentive Stock Option
Agreement attached hereto as Exhibit "A" and the three forms of a Nonstatutory
Stock Option Agreement for 

                                      -4-
<PAGE>
 
employees, for directors and for consultants, attached hereto as Exhibits "B-1,"
"B-2" and "B-3," respectively, shall be deemed to be approved by the Board.
Option agreements need not be identical, and in each case may include such
provisions as the Board or Committee may determine, but all such agreements
shall be subject to and limited by the following terms and conditions:

          (a) Number of Shares:  Each Option shall state the number of shares to
              ----------------                                                  
which it pertains.

          (b) Exercise Price:  Each Option shall state the exercise price, which
              --------------                                                    
shall be determined as follows:

               (i) Any Option granted to a person who at the time the Option is
     granted owns (or is deemed to own pursuant to Section 424(d) of the Code)
     stock possessing more than ten percent (10%) of the total combined voting
     power or value of all classes of stock of the Company, ("Ten Percent
     Holder") shall have an exercise price of no less than 110% of the Fair
     Market Value of the Stock as of the date of grant; and

               (ii) Incentive Stock Options granted to a person who at the time
     the Option is granted is not a Ten Percent Holder shall have an exercise
     price of no less than 100% of the Fair Market Value of the Class A Common
     Stock as of the date of grant.

               (iii)  Nonstatutory Options granted to a person who at the time
     the Option is granted is not a Ten Percent Holder shall have an exercise
     price of no less than 85% of the Fair Market Value of the Stock as of the
     date of grant.

          For the purposes of this Section 6(b), the Fair Market Value per share
shall be the average of the bid and asked prices (or the closing price if such
stock is listed on the NASDAQ National Market System or Small Cap Issue Market)
on the date of grant of the Option, or if listed on a stock exchange, the
closing price on such exchange on such date of grant; provided however, that if
there is no public market for such Stock, the Fair Market Value shall be as
determined by the Board in good faith, which determination shall be conclusive
and binding.

          (c) Medium and Time of Payment:  The exercise price shall become
              --------------------------                                  
immediately due upon exercise of the Option and shall be paid in cash or check
made payable to the Company.  Should the Company's outstanding Stock be
registered under Section 12(g) of the Exchange Act at the time the Option is
exercised, then the exercise price may also be paid as follows:

               (i) in shares of the Company's Stock held by the Optionee for the
     requisite period necessary to avoid a charge to the Company's earnings for
     financial 

                                      -5-
<PAGE>
 
     reporting purposes and valued at Fair Market Value on the exercise date, or

               (ii) through a special sale and remittance procedure pursuant to
     which the Optionee shall concurrently provide irrevocable written
     instructions (a) to a Company designated brokerage firm to effect the
     immediate sale of the purchased shares and remit to the Company, out of the
     sale proceeds available on the settlement date, sufficient funds to cover
     the aggregate exercise price payable for the purchased shares plus all
     applicable Federal, state and local income and employment taxes required to
     be withheld by the Company by reason of such purchase and (b) to the
     Company to deliver the certificates for the purchased shares directly to
     such brokerage firm in order to complete the sale transaction.

          At the discretion of the Board, exercisable either at the time of
Option grant or of Option exercise, the exercise price may also be paid (i) by
Optionee's delivery of a promissory note in form and substance satisfactory to
the Company and permissible under the California Securities Rules and bearing
interest at a rate determined by the Board in its sole discretion, but in no
event less than the minimum rate of interest required to avoid the imputation of
compensation income to the Optionee under the Federal tax laws, or (ii) in such
other form of consideration permitted by the California Corporations Code as may
be acceptable to the Board.

          (d) Term and Exercise of Options:  Any Option granted to an employee
              ----------------------------                                    
of the Company shall become exercisable over a period of no longer than five (5)
years, and no less than twenty percent (20%) of the shares covered thereby shall
become exercisable annually.  No Option shall be exercisable, in whole or in
part, prior to one (1) year from the date it is granted unless the Board shall
specifically determine otherwise, as provided herein.  In no event shall any
Option be exercisable after the expiration of ten (10) years from the date it is
granted, and no Incentive Stock Option granted to a Ten Percent Holder shall, by
its terms, be exercisable after the expiration of five (5) years from the date
of the Option.  Unless otherwise specified by the Board or the Committee in the
resolution authorizing such option, the date of grant of an Option shall be
deemed to be the date upon which the Board or the Committee authorizes the
granting of such Option.

          Each Option shall be exercisable to the nearest whole share, in
installments or otherwise, as the respective Option agreements may provide.
During the lifetime of an Optionee, the Option shall be exercisable only by the
Optionee and shall not be assignable or transferable by the Optionee, and no
other person shall acquire any rights therein.  To the extent not exercised,
installments (if more than one) shall accumulate, but shall be exercisable, in
whole or in part, only during the period for exercise as stated in the Option
agreement, whether or not other installments are then exercisable.

          (e) Termination of Status as Employee, Consultant or Director:  If
              ---------------------------------------------------------     
Optionee's status as an employee shall terminate for any reason other than
Optionee's disability or death, then the Optionee (or if the Optionee shall die
after such termination, but 

                                      -6-
<PAGE>
 
prior to exercise, Optionee's personal representative or the person entitled to
succeed to the Option) shall have the right to exercise the portions of any of
Optionee's Incentive Stock Options which were exercisable as of the date of such
termination, in whole or in part, not less than 30 days nor more than three (3)
months after such termination (or, in the event of "termination for cause" as
that term is defined in Section 2922 of the California Labor Code and case law
related thereto, or by the terms of the Plan or the Option Agreement or an
employment agreement, the Option shall automatically terminate as of the
termination of employment as to all shares covered by the Option).

          With respect to Nonstatutory Options granted to employees, directors
or consultants, the Board may specify such period for exercise, not less than 30
days (except that in the case of "termination for cause" or termination of a
director pursuant to Section 302 or 304 of the California Corporations Code, the
Option shall automatically terminate as of the termination of employment or
services as to shares covered by the Option), following termination of
employment or services as the Board deems reasonable and appropriate.  The
Option may be exercised only with respect to installments that the Optionee
could have exercised at the date of termination of employment or services.
Nothing contained herein or in any Option granted pursuant hereto shall be
construed to affect or restrict in any way the right of the Company to terminate
the employment or services of an Optionee with or without cause.

          (f) Disability of Optionee:  If an Optionee is disabled (within the
              ----------------------                                         
meaning of Section 22(e)(3) of the Code) at the time of termination, the three
(3) month period set forth in Section 6(e) shall be a period, as determined by
the Board and set forth in the Option, of not less than six months nor more than
one year after such termination.

          (g) Death of Optionee:  If an Optionee dies while employed by, engaged
              -----------------                                                 
as a consultant to, or serving as a Director of the Company, the portion of such
Optionee's Option which was exercisable at the date of death may be exercised,
in whole or in part, by the estate of the decedent or by a person succeeding to
the right to exercise such Option at any time within (i) a period, as determined
by the Board and set forth in the Option, of not less than six (6) months nor
more than one (1) year after Optionee's death, which period shall not be more,
in the case of a Nonstatutory Option, than the period for exercise following
termination of employment or services, or (ii) during the remaining term of the
Option, whichever is the lesser.  The Option may be so exercised only with
respect to installments exercisable at the time of Optionee's death and not
previously exercised by the Optionee.

          (h) Nontransferability of Option:  No Option shall be transferable by
              ----------------------------                                     
the Optionee, except by will or by the laws of descent and distribution.

          (i) Recapitalization:  Subject to any required action of shareholders,
              ----------------                                                  
the number of shares of Stock covered by each outstanding Option, and the
Exercise price per share thereof set forth in each such Option, shall be
proportionately adjusted for any increase or decrease in the number of issued
shares of Stock of the Company resulting from a 

                                      -7-
<PAGE>
 
subdivision or consolidation of shares or the payment of a stock dividend, or
any other increase or decrease in the number of such shares affected without
receipt of consideration by the Company; provided, however, the conversion of
any convertible securities of the Company shall not be deemed to have been
"effected" without receipt of consideration by the Company.

          In the event of a proposed dissolution or liquidation of the Company,
a merger or consolidation in which the Company is not the surviving entity, or a
sale of all or substantially all of the assets or capital stock of the Company
(collectively, a "Reorganization"), unless otherwise provided by the Board, this
Option shall terminate immediately prior to such date as is determined by the
Board, which date shall be no later than the consummation of such
Reorganization.  In such event, if the entity which shall be the surviving
entity does not tender to Optionee an offer, for which it has no obligation to
do so, to substitute for any unexercised Option a stock option or capital stock
of such surviving entity, as applicable, which on an equitable basis shall
provide the Optionee with substantially the same economic benefit as such
unexercised Option, then the Board may grant to such Optionee, in its sole and
absolute discretion and without obligation, the right for a period commencing
thirty (30) days prior to and ending immediately prior to the date determined by
the Board pursuant hereto for termination of the Option or during the remaining
term of the Option, whichever is the lesser, to exercise any unexpired Option or
Options without regard to the installment provisions of Paragraph 6(d) of the
Plan; provided, that any such right granted shall be granted to all Optionees
not receiving an offer to receive substitute options on a consistent basis, and
provided further, that any such exercise shall be subject to the consummation of
such Reorganization.

          Subject to any required action of shareholders, if the Company shall
be the surviving entity in any merger or consolidation, each outstanding Option
thereafter shall pertain to and apply to the securities to which a holder of
shares of Class A Common Stock equal to the shares subject to the Option would
have been entitled by reason of such merger or consolidation.

          In the event of a change in the Class A Common Stock of the Company as
presently constituted, which is limited to a change of all of its authorized
shares without par value into the same number of shares with a par value, the
shares resulting from any such change shall be deemed to be the Stock within the
meaning of the Plan.

          To the extent that the foregoing adjustments relate to stock or
securities of the Company, such adjustments shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive.  Except as
expressly provided in this Section 6(i), the Optionee shall have no rights by
reason of any subdivision or consolidation of shares of stock of any class or
the payment of any stock dividend or any other increase or decrease in the
number of shares of stock of any class, and the number or price of shares of
Stock subject to any Option shall not be affected by, and no adjustment shall be
made by reason of, any dissolution, liquidation, merger, consolidation or sale
of assets or capital stock, or any issue by the Company of shares of stock of
any class or securities convertible into 

                                      -8-
<PAGE>
 
shares of stock of any class.

          The grant of an Option pursuant to the Plan shall not affect in any
way the right or power of the Company to make any adjustments,
reclassifications, reorganizations or changes in its capital or business
structure or to merge, consolidate, dissolve, or liquidate or to sell or
transfer all or any part of its business or assets.

          (j) Rights as a Shareholder:  An Optionee shall have no rights as a
              -----------------------                                        
shareholder with respect to any shares covered by an Option until the effective
date of the issuance of the shares following exercise of such Option by
Optionee.  No adjustment shall be made for dividends (ordinary or extraordinary,
whether in cash, securities or other property) or distributions or other rights
for which the record date is prior to the date such stock certificate is issued,
except as expressly provided in Section 6(i) hereof.

          (k) Modification, Acceleration, Extension, and Renewal of Options:
              -------------------------------------------------------------  
Subject to the terms and conditions and within the limitations of the Plan, the
Board may modify an Option, or, once an Option is exercisable, accelerate the
rate at which it may be exercised, and may extend or renew outstanding Options
granted under the Plan or accept the surrender of outstanding Options (to the
extent not theretofore exercised) and authorize the granting of new Options in
substitution for such Options, provided such action is permissible under Section
422 of the Code and the California Securities Rules.  Notwithstanding the
provisions of this Section 6(k), however, no modification of an Option shall,
without the consent of the Optionee, alter to the Optionee's detriment or impair
any rights or obligations under any Option theretofore granted under the Plan.

          (l) Exercise Before Exercise Date:  At the discretion of the Board,
              -----------------------------                                  
the Option may, but need not, include a provision whereby the Optionee may elect
to exercise all or any portion of the Option prior to the stated exercise date
of the Option or any installment thereof. Any shares so purchased prior to the
stated exercise date shall be subject to repurchase by the Company upon
termination of Optionee's employment as contemplated by Section 6(n) hereof
prior to the exercise date stated in the Option and such other restrictions and
conditions as the Board or Committee may deem advisable.

          (m) Other Provisions:  The Option agreements authorized under the Plan
              ----------------                                                  
shall contain such other provisions, including, without limitation, restrictions
upon the exercise of the Options, as the Board or the Committee shall deem
advisable.  Shares shall not be issued pursuant to the exercise of an Option, if
the exercise of such Option or the issuance of shares thereunder would violate,
in the opinion of legal counsel for the Company, the provisions of any
applicable law or the rules or regulations of any applicable governmental or
administrative agency or body, such as the Code, the Securities Act, the
Exchange Act, the California Securities Rules, California Corporations Code, and
the rules promulgated under the foregoing or the rules and regulations of any
exchange upon which the shares of the Company are listed.  Without limiting the
generality of the foregoing, the exercise of each 

                                      -9-
<PAGE>
 
Option shall be subject to the condition that if at any time the Company shall
determine that (i) the satisfaction of withholding tax or other similar
liabilities, or (ii) the listing, registration or qualification of any shares
covered by such exercise upon any securities exchange or under any state or
federal law, or (iii) the consent or approval of any regulatory body, or (iv)
the perfection of any exemption from any such withholding, listing,
registration, qualification, consent or approval is necessary or desirable in
connection with such exercise or the issuance of shares thereunder, then in any
such event, such exercise shall not be effective unless such withholding,
listing registration, qualification, consent, approval or exemption shall have
been effected, obtained or perfected free of any conditions not acceptable to
the Corporation.

          (n) Repurchase Agreement:  The Board may, in its discretion, require
              --------------------                                            
as a condition to the grant of an Option hereunder, that an Optionee execute an
agreement with the Company, in form and substance satisfactory to the Board in
its discretion ("Repurchase Agreement"), (i) restricting the Optionee's right to
transfer shares purchased under such Option without first offering such shares
to the Company or another shareholder of the Company upon the same terms and
conditions as provided therein; and (ii) providing that upon termination of
Optionee's employment with the Company, for any reason, the Company (or another
shareholder of the Company, as provided in the Repurchase Agreement) shall have
the right at its discretion (or the discretion of such other shareholders) to
purchase and/or redeem all such shares owned by the Optionee on the date of
termination of his or her employment at a price equal to (A) the  fair value of
such shares as of such date of termination, or (B) if such repurchase right
lapses at 20% of the number of shares per year, the original purchase price of
such shares, and upon terms of payment permissible under the California
Securities Rules; provided that in the case of Options or Stock Awards granted
to officers, directors, consultants or affiliates of the Company, such
repurchase provisions may be subject to additional or greater restrictions as
determined by the Board or Committee.

     7.  STOCK AWARDS AND RESTRICTED STOCK PURCHASE OFFERS

          (a)  Types of Grants.
               ----------------

               (i) Stock Award .  All or part of any Stock Award under the Plan
                   ------------                                                
     may be subject to conditions established by the Board or the Committee, and
     set forth in the Stock Award Agreement, which may include, but are not
     limited to, continuous service with the Company, achievement of specific
     business objectives, increases in specified indices, attaining growth rates
     and other comparable measurements of Company performance.  Such Awards may
     be based on Fair Market Value or other specified valuation.  All Stock
     Awards will be made pursuant to the execution of a Stock Award Agreement
     substantially in the form attached hereto as Exhibit "C".

               (ii)  Restricted Stock Purchase Offer.  A Grant of a Restricted
                     -------------------------------                          
     Stock Purchase Offer under the Plan shall be subject to such (i) vesting
     contingencies related to the Participant's continued association with the
     Company 

                                      -10-
<PAGE>
 
     for a specified time and (ii) other specified conditions as the Board or
     Committee shall determine, in their sole discretion, consistent with the
     provisions of the Plan. All Restricted Stock Purchase Offers shall be made
     pursuant to a Restricted Stock Purchase Offer substantially in the form
     attached hereto as Exhibit "D".

          (b) Conditions and Restrictions.  Shares of Stock which  Participants
              ----------------------------                                     
may receive as a Stock Award under a Stock Award Agreement or Restricted Stock
Purchase Offer under a Restricted Stock Purchase Offer may include such
restrictions as the Board or Committee, as applicable, shall determine,
including restrictions on transfer, repurchase rights, right of first refusal,
and forfeiture provisions.  When transfer of Stock is so restricted or subject
to forfeiture provisions it is referred to as "Restricted Stock".  Further, with
Board or Committee approval, Stock Awards or Restricted Stock Purchase Offers
may be deferred, either in the form of installments or a future lump sum
distribution.  The Board or Committee may permit selected Participants to elect
to defer distributions of Stock Awards or Restricted Stock Purchase Offers in
accordance with procedures established by the Board or Committee to assure that
such deferrals comply with applicable requirements of the Code including, at the
choice of Participants, the capability to make further deferrals for
distribution after retirement. Any deferred distribution, whether elected by the
Participant or specified by the Stock Award Agreement, Restricted Stock Purchase
Offers or by the Board or Committee, may require the payment be forfeited in
accordance with the provisions of Section 7(c).  Dividends or dividend
equivalent rights may be extended to and made part of any Stock Award or
Restricted Stock Purchase Offers denominated in Stock or units of Stock, subject
to such terms, conditions and restrictions as the Board or Committee may
establish.

          (c) Cancellation and Rescission of Grants.  Unless the Stock Award
              --------------------------------------                        
Agreement or Restricted Stock Purchase Offer specifies otherwise, the Board or
Committee, as applicable, may cancel any unexpired, unpaid, or deferred Grants
at any time if the Participant is not in compliance with all other applicable
provisions of the Stock Award Agreement or Restricted Stock Purchase Offer, the
Plan and with the following conditions:

               (i) A Participant shall not render services for any organization
     or engage directly or indirectly in any business which, in the judgment of
     the chief executive officer of the Company or other senior officer
     designated by the Board or Committee, is or becomes competitive with the
     Company, or which organization or business, or the rendering of services to
     such organization or business, is or becomes otherwise prejudicial to or in
     conflict with the interests of the Company.  For Participants whose
     employment has terminated, the judgment of the chief executive officer
     shall be based on the Participant's position and responsibilities while
     employed by the Company, the Participant's post-employment responsibilities
     and position with the other organization or business, the extent of past,
     current and potential competition or conflict between the Company and the
     other organization or business, the effect on the Company's customers,
     suppliers and competitors and such other considerations as are deemed
     relevant given the applicable facts and circumstances.  A Participant who
     has retired shall be free, however, to purchase as 

                                      -11-
<PAGE>
 
     an investment or otherwise, stock or other securities of such organization
     or business so long as they are listed upon a recognized securities
     exchange or traded over-the-counter, and such investment does not represent
     a substantial investment to the Participant or a greater than 10 percent
     equity interest in the organization or business.

               (ii) A Participant shall not, without prior written authorization
     from the Company, disclose to anyone outside the Company, or use in other
     than the Company's business, any confidential information or material, as
     defined in the Company's Proprietary Information and Invention Agreement or
     similar agreement regarding confidential information and intellectual
     property, relating to the business of the Company, acquired by the
     Participant either during or after employment with the Company.

               (iii)  A Participant, pursuant to the Company's Proprietary
     Information and Invention Agreement, shall disclose promptly and assign to
     the Company all right, title and interest in any invention or idea,
     patentable or not, made or conceived by the Participant during employment
     by the Company, relating in any manner to the actual or anticipated
     business, research or development work of the Company and shall do anything
     reasonably necessary to enable the Company to secure a patent where
     appropriate in the United States and in foreign countries.

               (iv) Upon exercise, payment or delivery pursuant to a Grant, the
     Participant shall certify on a form acceptable to the Committee that he or
     she is in compliance with the terms and conditions of the Plan.  Failure to
     comply with all of the provisions of this Section 7(c) prior to, or during
     the six months after, any exercise, payment or delivery pursuant to a Grant
     shall cause such exercise, payment or delivery to be rescinded.  The
     Company shall notify the Participant in writing of any such rescission
     within two years after such exercise, payment or delivery.  Within ten days
     after receiving such a notice from the Company, the Participant shall pay
     to the Company the amount of any gain realized or payment received as a
     result of the rescinded exercise, payment or delivery pursuant to a Grant.
     Such payment shall be made either in cash or by returning to the Company
     the number of shares of Stock that the Participant received in connection
     with the rescinded exercise, payment or delivery.

          (d)  Nonassignability.
               -----------------

               (i) Except pursuant to Section 7(e)(iii) and except as set forth
     in  Section 7(d)(ii), no Grant or any other benefit under the Plan shall be
     assignable or transferable, or payable to or exercisable by, anyone other
     than the Participant to whom it was granted.

               (ii) Where a Participant terminates employment and retains a

                                      -12-
<PAGE>
 
     Grant pursuant to Section 7(e)(ii) in order to assume a position with a
     governmental, charitable or educational institution, the Board or
     Committee, in its discretion and to the extent permitted by law, may
     authorize a third party (including but not limited to the trustee of a
     "blind" trust), acceptable to the applicable governmental or institutional
     authorities, the Participant and the Board or Committee, to act on behalf
     of the Participant with regard to such Awards.

          (e) Termination of Employment.  If the employment or service to the
              -------------------------                                      
Company of a Participant terminates, other than pursuant to any of the following
provisions under this Section 7(e), all unexercised, deferred and unpaid Stock
Awards or Restricted Stock Purchase Offers shall be cancelled immediately,
unless the Stock Award Agreement or Restricted Stock Purchase Offer provides
otherwise:

               (i) Retirement Under a Company Retirement Plan.  When a
                   ------------------------------------------         
     Participant's employment terminates as a result of retirement in accordance
     with the terms of a Company retirement plan, the Board or Committee may
     permit Stock Awards or Restricted Stock Purchase Offers to continue in
     effect beyond the date of retirement in accordance with the applicable
     Grant Agreement and the exercisability and vesting of any such Grants may
     be accelerated.

               (ii) Resignation in the Best Interests of the Company.  When a
                    ------------------------------------------------         
     Participant resigns from the Company and, in the judgment of the Board or
     Committee, the acceleration and/or continuation of outstanding Stock Awards
     or Restricted Stock Purchase Offers would be in the best interests of the
     Company, the Board or Committee may (i) authorize, where appropriate, the
     acceleration and/or continuation of all or any part of Grants issued prior
     to such termination and (ii) permit the exercise, vesting and payment of
     such Grants for such period as may be set forth in the applicable Grant
     Agreement, subject to earlier cancellation pursuant to Section 10 or at
     such time as the Board or Committee shall deem the continuation of all or
     any part of the Participant's Grants are not in the Company's best
     interest.

               (iii)  Death or Disability of a Participant.
                      ------------------------------------ 

                      (1)  In the event of a Participant's death, the
     Participant's estate or beneficiaries shall have a period up to the
     expiration date specified in the Grant Agreement within which to receive or
     exercise any outstanding Grant held by the Participant under such terms as
     may be specified in the applicable Grant Agreement.  Rights to any such
     outstanding Grants shall pass by will or the laws of descent and
     distribution in the following order: (a) to beneficiaries so designated by
     the Participant; if none, then (b) to a legal representative of the
     Participant; if none, then (c) to the persons entitled thereto as
     determined by a court of competent jurisdiction. Grants so passing shall be
     made at such times and in such manner as if the Participant were living.

                                      -13-
<PAGE>
 
                      (2)  In the event a Participant is deemed by the Board or
     Committee, to be unable to perform his or her usual duties by reason of
     mental disorder or medical condition which does not result from facts which
     would be grounds for termination for cause, Grants and rights to any such
     Grants may be paid to or exercised by the Participant, if legally
     competent, or a committee or other legally designated guardian or
     representative if the Participant is legally incompetent by virtue of such
     disability.

                      (3)  After the death or disability of a Participant, the
     Board or Committee may in its sole discretion at any time (1) terminate
     restrictions in Grant Agreements; (2) accelerate any or all installments
     and rights; and (3) instruct the Company to pay the total of any
     accelerated payments in a lump sum to the Participant, the Participant's
     estate, beneficiaries or representative - notwithstanding that, in the
     absence of such termination of restrictions or acceleration of payments,
     any or all of the payments due under the Grant might ultimately have become
     payable to other beneficiaries.

                      (4)  In the event of uncertainty as to interpretation of
     or controversies concerning this Section 7, the determinations of the Board
     or Committee, as applicable, shall be binding and conclusive.

     8.  INVESTMENT INTENT

          All Grants under the Plan are intended to be exempt from registration
under the Securities Act provided by Rule 701 thereunder.  Unless and until the
granting of Options or sale and issuance of Stock subject to the Plan are
registered under the Securities Act or shall be exempt pursuant to the rules
promulgated thereunder, each Grant under the Plan shall provide that the
purchases or other acquisitions of Stock thereunder shall be for investment
purposes and not with a view to, or for resale in connection with, any
distribution thereof. Further, unless the issuance and sale of the Stock have
been registered under the Securities Act, each Grant shall provide that no
shares shall be purchased upon the exercise of the rights under such Grant
unless and until (i) all then applicable requirements of state and federal laws
and regulatory agencies shall have been fully complied with to the satisfaction
of the Company and its counsel, and (ii) if requested to do so by the Company,
the person exercising the rights under the Grant shall (i) give written
assurances as to knowledge and experience of such person (or a representative
employed by such person) in financial and business matters and the ability of
such person (or representative) to evaluate the merits and risks of exercising
the Option, and (ii) execute and deliver to the Company a letter of investment
intent and/or such other form related to applicable exemptions from
registration, all in such form and substance as the Company may require.  If
shares are issued upon exercise of any rights under a Grant without registration
under the Securities Act, subsequent registration of such shares shall relieve
the purchaser thereof of any investment restrictions or representations made
upon the exercise of such rights.

                                      -14-
<PAGE>
 
     9.  AMENDMENT, MODIFICATION, SUSPENSION OR DISCONTINUANCE OF THE PLAN.

          The Board may, insofar as permitted by law, from time to time, with
respect to any shares at the time not subject to outstanding Grants, suspend or
terminate the Plan or revise or amend it in any respect whatsoever, except that
without the approval of the shareholders of the Company, no such revision or
amendment shall (i) increase the number of shares subject to the Plan, (ii)
decrease the price at which Grants may be granted, (iii) materially increase the
benefits to Participants, or (iv) change the class of persons eligible to
receive Grants under the Plan; provided, however, no such action shall alter or
impair the rights and obligations under any Option, or Stock Award, or
Restricted Stock Purchase Offer outstanding as of the date thereof without the
written consent of the Participant thereunder.  No Grant may be issued while the
Plan is suspended or after it is terminated, but the rights and obligations
under any Grant issued while the Plan is in effect shall not be impaired by
suspension or termination of the Plan.

          In the event of any change in the outstanding Stock by reason of a
stock split, stock dividend, combination or reclassification of shares,
recapitalization, merger, or similar event, the Board or the Committee may
adjust proportionally (a) the number of shares of Stock (i) reserved under the
Plan, (ii) available for Incentive Stock Options and Nonstatutory Options and
(iii) covered by outstanding Stock Awards or Restricted Stock Purchase Offers;
(b) the Stock prices related to outstanding Grants; and (c) the appropriate Fair
Market Value and other price determinations for such Grants.  In the event of
any other change affecting the Stock or any distribution (other than normal cash
dividends) to holders of Stock, such adjustments as may be deemed equitable by
the Committee, including adjustments to avoid fractional shares, shall be made
to give proper effect to such event.  In the event of a corporate merger,
consolidation, acquisition of property or stock, separation, reorganization or
liquidation, the Committee shall be authorized to issue or assume stock options,
whether or not in a transaction to which Section 424(a) of the Code applies, and
other Grants by means of substitution of new Grant Agreements for previously
issued Grants or an assumption of previously issued Grants.

     10.  TAX WITHHOLDING.

          The Company shall have the right to deduct applicable taxes from any
Grant payment and withhold, at the time of delivery or exercise of Options,
Stock Awards or Restricted Stock Purchase Offers or vesting of shares under such
Grants, an appropriate number of shares for payment of taxes required by law or
to take such other action as may be necessary in the opinion of the Company to
satisfy all obligations for withholding of such taxes.  If Stock is used to
satisfy tax withholding, such stock shall be valued based on the Fair Market
Value when the tax withholding is required to be made.

                                      -15-
<PAGE>
 
     11.  AVAILABILITY OF INFORMATION.

          During the term of the Plan and any additional period during which a
Grant granted pursuant to the Plan shall be exercisable, the Company shall make
available, not later than one hundred and twenty (120) days following the close
of each of its fiscal years, such financial and other information regarding the
Company as is required by the bylaws of the Company and applicable law to be
furnished in an annual report to the shareholders of the Company.

     12.  NOTICE.

          Any written notice to the Company required by any of the provisions of
the Plan shall be addressed to the chief personnel officer or to the chief
executive officer of the Company, and shall become effective when it is received
by the office of the chief personnel officer or the chief executive officer.

     13.  UNFUNDED PLAN.

          Insofar as it provides for Grants, the Plan shall be unfunded.
Although bookkeeping accounts may be established with respect to Participants
who are entitled to Grants or rights thereto under the Plan, any such accounts
shall be used merely as a bookkeeping convenience.  The Company shall not be
required to segregate any assets that may at any time be represented by Grants
or rights thereto, nor shall the Plan be construed as providing for such
segregation, nor shall the Company nor the Board nor the Committee be deemed to
be a trustee of any Grants or rights thereto to be granted under the Plan.  Any
liability of the Company to any Participant with respect to a grant of Stock or
rights thereto under the Plan shall be based solely upon any contractual
obligations that may be created by the Plan and any Grant Agreement; no such
obligation of the Company shall be deemed to be secured by any pledge or other
encumbrance on any property of the Company.  Neither the Company nor the Board
nor the Committee shall be required to give any security or bond for the
performance of any obligation that may be created by the Plan.

     14.  INDEMNIFICATION OF BOARD

          In addition to such other rights or indemnifications as they may have
as directors or otherwise, and to the extent allowed by applicable law, the
members of the Board and the Committee shall be indemnified by the Company
against the reasonable expenses, including attorneys' fees, actually and
necessarily incurred in connection with the defense of any claim, action, suit
or proceeding, or in connection with any appeal thereof, to which they or any of
them may be a party by reason of any action taken, or failure to act, under or
in connection with the Plan or any Grant granted thereunder, and against all
amounts paid by them in settlement thereof (provided such settlement is approved
by independent legal counsel selected by the Company) or paid by them in
satisfaction of a judgment in any such claim, action, suit or proceeding, except
in any case in relation to matters as to which it shall be 

                                      -16-
<PAGE>
 
adjudged in such claim, action, suit or proceeding that such Board or Committee
member is liable for negligence or misconduct in the performance of his or her
duties; provided that within sixty (60) days after institution of any such
action, suit or Board proceeding the member involved shall offer the Company, in
writing, the opportunity, at its own expense, to handle and defend the same.

     15.  GOVERNING LAW.

          The Plan and all determinations made and actions taken pursuant
hereto, to the extent not otherwise governed by the Code or the securities laws
of the United States, shall be governed by the law of the State of California
and construed accordingly.

     16.  EFFECTIVE AND TERMINATION DATES.

          The Plan shall become effective on the date it is approved by the
holders of a majority of the shares of Stock then outstanding.  The Plan shall
terminate ten years later, subject to earlier termination by the Board pursuant
to Section 9.

                               NETVANTAGE, INC.

                 1996 BONUS AND NONSTATUTORY STOCK OPTION PLAN


1.   Purpose
     -------

     This Bonus and Nonstatutory Stock Option Plan (the "Plan") is intended to
further the growth and financial success of NETVANTAGE, INC. (the "Corporation")
by providing additional incentives to Executive officers and selected
consultants to the Corporation or parent corporation or subsidiary corporation
of the Corporation as those terms are defined in Sections 424(e) and 424(f) of
the Internal Revenue Code of 1986, as amended (the "Revenue Code") (such parent
corporations and subsidiary corporations hereinafter collectively referred to as
"Affiliates"), provided such persons  are California residents and meet the
investor suitability standards pursuant to Section 25102(f) of the California
Corporations Code ("CA Code"). Stock options granted under the Plan (hereinafter
"Options") may only be "Nonstatutory Options" (i.e. not intended as Incentive
Stock Options under Section 422 of the Revenue Code) as reflected in the written
stock option agreements granted pursuant hereto, and are not assignable except
as specifically set forth herein.

2.   Administration
     --------------

     The Plan shall be administered by the Board of Directors of the Corporation
(the "Board") provided however, that any bonuses or Options granted to executive
officers hereunder shall be approved by a majority of those directors who are
the "disinterested", as contemplated by Rule 16b-3 promulgated under the
Securities Exchange Act of 1934, as amended ("Rule 16b-3").

     Subject to the provisions of the Plan, the Board shall have authority to
(a) grant bonuses and/or Nonstatutory Options; (b) determine in good faith the
fair market value of the stock covered by an Option; (c) determine which
eligible persons shall be granted bonuses and/or Options; (d) determine the
number of shares, exercise price, term and vesting conditions of any Options;
(e) construe and interpret the Plan; (f) promulgate, amend and rescind rules and
regulations relating to its administration, and correct defects, omissions and
inconsistencies in the Plan or any Option; (f) consistent with the Plan and with
the consent of the Participant, as appropriate, amend any outstanding Bonus
agreement or Option or amend the exercise date or dates thereof and (g) make all
other determinations necessary or advisable for the Plan's administration.  The
interpretation and construction by the Board of any provisions of the Plan, any
Option or any bonus agreement  shall be conclusive and final.  No member of the
Board shall be liable for any action or determination made in good faith with
respect to the Plan or any bonus or Option.

                                      -1-
<PAGE>
 
3.   Eligibility
     -----------

     The persons who shall be eligible to receive bonuses and/or Options shall
be executive officers of or consultants to the Corporation or any of its
Affiliates ("Participants").  The term consultant shall mean any person who is
engaged by the Corporation to render services and is compensated for such
services.  THE TOTAL NUMBER OF PERSONS TO WHOM OPTIONS MAY BE GRANTED HEREUNDER
IS LIMITED TO THIRTY-FIVE PERSONS EACH OF WHOM MEETS THE REQUIREMENTS SET FORTH
IN SECTION 25102(f) OF THE CA CODE AND THE SECURITIES RULES PROMULGATED
THEREUNDER.

4.   Bonuses   The aggregate amount of funds available for the grant of bonuses
     -------
under this Plan is $300,000.  Such bonuses shall be granted upon such terms and
conditions as are proposed by the Chief Executive Officer and Chief Financial
Officer of the Corporation and approved by the Board of Directors.

5.   Stock
     -----

     The stock subject to Options shall be shares of the Corporation's
authorized but unissued or reacquired common stock (the "Stock").

          (a) Number of Shares.  Subject to adjustment as provided in Paragraph
              ----------------                                                 
6(i) of this Plan, the total number of shares of Stock which may be purchased
through exercise of Options granted under this Plan shall not exceed 105,000.
If any Option shall for any reason terminate or expire, any shares allocated
thereto but remaining unpurchased upon such expiration or termination shall
again be available for the grant of Options with respect thereto under this Plan
as though no Option had been granted with respect to such shares.

          (b) Reservation of Shares. The Corporation shall reserve and keep
              ---------------------                                        
available at all times during the term of the Plan such number of shares as
shall be sufficient to satisfy the requirements of the Plan.  If, after
reasonable efforts, which efforts shall not include the registration of the Plan
or Options under the Securities Act of 1933, the Corporation is unable to obtain
authority from any applicable regulatory body, which authorization is deemed
necessary by legal counsel for the Corporation for the lawful issuance of shares
hereunder, the Corporation shall be relieved of any liability with respect to
its failure to issue and sell the shares for which such requisite authority was
so deemed necessary unless and until such authority is obtained.

          (c) Application of Funds.   The proceeds received by the Corporation
              --------------------
from the sale of common stock pursuant to the exercise of Options will be used
for general corporate purposes.

6.   Terms and Conditions of Options
     -------------------------------

                                      -2-
<PAGE>
 
     Each Option granted hereunder shall be designated as a "Nonstatutory Stock
Option Agreement" and shall set forth the intention of the parties that it be a
Nonstatutory Option.  Options granted hereunder shall be evidenced by agreements
between the Corporation and the respective Participants, in such form and
substance as the Board shall from time to time approve.  Such agreements need
not be identical, and in each case may include such provisions as the Board may
determine, but all such agreements shall be subject to and limited by the
following terms and conditions:

          (a) Number of Shares: Each Option shall state the number of shares to
              ----------------                                                 
which it pertains.

          (b) Option Price: Each Option shall state the Option Price, which in
              ------------                                                    
no event shall be less than 85% of the fair market value of the common stock as
of the date of grant.  For the purposes of this Paragraph 6(b), the fair market
value shall be the average of the bid and asked prices (or the closing price if
such stock is listed on the NASDAQ National Market System) on the date of grant
of the Option, or if listed on a stock exchange, the closing price on such
exchange on such date of grant.

          (c) Medium and Time of Payment: To the extent permissible by
              --------------------------                              
applicable law, the Option price shall be paid, at the discretion of the Board,
at either the time of grant or the time of exercise of the Option (i) in cash or
by check, (ii) by delivery of other common stock of the Corporation, provided
such tendered stock was not acquired directly or indirectly from the
Corporation, or, if acquired from the Corporation, has been held by the
Participant for more than six (6) months, (iii) by the Participant's promissory
note in a form satisfactory to the Corporation and bearing interest at a rate
determined by the Board, in its sole discretion, but in no event less than 6%
per annum, or (iv) such other form of legal consideration permitted by the
California Corporations Code as may be acceptable to the Board.

          (d) Term and Exercise of Options:  Any Option granted hereunder shall
              ----------------------------                                     
become exercisable at such times or upon the occurrences of such events as are
determined by the Board; provided that no Option shall be exercisable after the
expiration of six (6) years from the date it is granted.  Unless otherwise
specified by the Board in the resolution authorizing such option, the date of
grant of an Option shall be deemed to be the date upon which the Board
authorizes the granting of such Option.

          Each Option shall be exercisable to the nearest whole share, in
installments or otherwise, as the respective option agreements may provide.
During the lifetime of a Participant, the Option shall be exercisable only by
the Participant and shall not be assignable or transferable by the Participant,
and no other person shall acquire any rights therein.  To the extent not
exercised, installments (if more than one) shall accumulate, but shall be
exercisable, in whole or in part, only during the period for exercise as stated
in the option agreement, whether or not other installments are then exercisable.

                                      -3-
<PAGE>
 
          (e) Termination of Status as Employee or Consultant: If Participant's
              -----------------------------------------------                  
status as an Executive officer or consultant shall terminate for any reason
other than Participant's disability or death, then the Participant (or if the
Participant shall die after such termination, but prior to exercise,
Participant's personal representative or the person entitled to succeed to the
Option) shall have the right to exercise the portions of any of Participant's
Options which were exercisable as of the date of such termination, in whole or
in part, at any time during the remaining term of the Option, or such shorter
period as determined by the Board and set forth in the Option agreement;
provided that, absent a termination "for cause" as contemplated by the
California Labor Code, such period shall not be shorter than (i) ninety (90)
days or (ii) the remaining term of the Option, whichever is lesser. The Option
may not be exercised with respect to installments that the Participant could not
have exercised at the date of termination. Nothing contained herein or in any
Option granted pursuant hereto shall be construed to affect or restrict in any
way the right of the Corporation to terminate or otherwise discharge Participant
with or without cause.

          (f) Nontransferability of Option: No Option shall be transferable by
              ----------------------------                                    
the Participant, except by will or by the laws of descent and distribution.

          (g) Recapitalization: Subject to any required action of stockholders,
              ----------------                                                 
the number of shares of common stock covered by each outstanding Option, and the
price per share thereof set forth in each such Option, shall be proportionately
adjusted for any increase or decrease in the number of issued shares of common
stock of the Corporation resulting from a subdivision or consolidation of shares
or the payment of a stock dividend, or any other increase or decrease in the
number of such shares affected without receipt of consideration by the
Corporation.

          Subject to any required action of stockholders, if the Corporation
shall be the surviving entity in any merger or consolidation, each outstanding
Option thereafter shall pertain to and apply to the securities to which a holder
of shares of common stock equal to the shares subject to the Option would have
been entitled by reason of such merger or consolidation.  In the event of a
proposed dissolution or liquidation of the Company, a merger or consolidation in
which the Company is not the surviving entity, or a sale of all or substantially
all of the assets or capital stock of the Company (collectively, a
"Reorganization"), unless otherwise provided by the Board, this Option shall
terminate immediately prior to such date as is determined by the Board, which
date shall be no later than the consummation of such Reorganization.  In such
event, if the entity which shall be the surviving entity does not tender to
Participant an offer, for which it has no obligation to do so, to substitute for
any unexercised Option a stock option or capital stock of such surviving entity,
as applicable, which on an equitable basis shall provide the Participant with
substantially the same economic benefit as such unexercised Option, then the
Board may grant to such Participant, in its sole and absolute discretion and
without obligation, the right for a period commencing thirty (30) days prior to
and ending immediately prior to the date determined by the Board pursuant hereto
for

                                      -4-
<PAGE>
 
termination of the Option or during the remaining term of the Option, whichever
is the lesser, to exercise any unexpired Option or Options without regard to the
vesting provisions of Paragraph 6(d) of the Plan; provided, that any such right
granted shall be granted to all Participants not receiving an offer to receive
substitute options on a consistent basis, and provided further, that any such
exercise shall be subject to the consummation of such Reorganization.

          In the event of a change in the common stock of the Corporation as
presently constituted, which is limited to a change of all of its authorized
shares without par value into the same number of shares with a par value, the
shares resulting from any such change shall be deemed to be the common stock
within the meaning of this Plan.

          To the extent that the foregoing adjustments relate to stock or
securities of the Corporation, such adjustments shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided in this Paragraph 6(g), the Participant shall have
no rights by reason of any subdivision or consolidation of shares of stock of
any class or the payment of any stock dividend or any other increase or decrease
in the number of shares of stock of any class, and the number or price of shares
of common stock subject to any Option shall not be affected by, and no
adjustment shall be made by reason of, any Reorganization or any issue by the
Corporation of shares of stock of any class or securities convertible into
shares of stock of any class.

          The grant of an Option pursuant to the Plan shall not affect in any
way the right or power of the Corporation to make any adjustments,
reclassifications, reorganizations or changes in its capital or business
structure or to merge, consolidate, dissolve, or liquidate or to sell or
transfer all or any part of its business or assets.

          (h) Rights as a Stockholder: A Participant shall have no rights as a
              -----------------------                                          
stockholder with respect to any shares covered by an Option until the date of
the issuance of a stock certificate to Participant for such shares.  No
adjustment shall be made for dividends (ordinary or extraordinary, whether in
cash, securities or other property) or distributions or other rights for which
the record date is prior to the date such stock certificate is issued, except as
expressly provided in Paragraph 6(g) hereof.

          (i) Modification, Acceleration, Extension, and Renewal of Options:
              ------------------------------------------------------------- 
Subject to the terms and conditions and within the limitations of the Plan and
of the Revenue Code the Board may modify an Option, or once an Option is
exercisable, accelerate the rate at which it may be exercised, and may extend or
renew outstanding Options granted under the Plan or accept the surrender of
outstanding Options (to the extent not theretofore exercised) and authorize the
granting of new Options in substitution for such Options, subject to any
limitations as may be applicable under Section 424 of the Revenue Code and
Section 260.140.41 of the Corporate 

                                      -5-
<PAGE>
 
Securities Rules of the California Corporations Commissioner. Notwithstanding
the provisions of this Paragraph 6(i), however, no modification of an Option
shall, without the consent of the Participant, alter to the Participant's
detriment or impair any rights or obligations under any Option theretofore
granted under the Plan.

          (j) Investment Intent: Unless and until the issuance and sale of the
              -----------------                                               
shares subject to the Plan are registered under the Securities Act of 1933, as
amended (the "Act"), each Option under the Plan shall provide that the purchases
of stock thereunder shall be for investment purposes and not with a view to, or
for resale in connection with, any distribution thereof.  Further, unless the
issuance and sale of the stock have been registered under the Act, each Option
shall provide that no shares shall be purchased upon the exercise of such Option
unless and until (i) any then applicable requirements of state and federal laws
and regulatory agencies shall have been fully complied with to the satisfaction
of the Corporation and its counsel, and (ii) if requested to do so by the
Corporation, the person exercising the Option shall (i) give written assurances
as to knowledge and experience of such person (or a representative employed by
such person) in financial and business matters and the ability of such person
(or representative) to evaluate the merits and risks of exercising the Option,
and (ii) execute and deliver to the Corporation a letter of investment intent,
all in such form and substance as the Corporation may require.  If shares are
issued upon exercise of an Option without registration under the Act, subsequent
registration of such shares shall relieve the purchaser thereof of any
investment restrictions or representations made upon the exercise of such
Options.

          (k) Exercise Before Exercise Date: At the discretion of the Board, the
              -----------------------------                                     
Option may, but need not, include a provision whereby the Participant may elect
to exercise all or any portion of the Option prior to the stated exercise date
of the Option or any installment thereof.  Any shares so purchased prior to the
stated exercise date shall be subject to repurchase by the Corporation upon
termination of Participant's employment as contemplated by Paragraph 6(e) hereof
prior to the exercise date stated in the Option and such other restrictions and
conditions as the Board may deem advisable.

          (l) No Obligation to Exercise Option:  The granting of an Option shall
              --------------------------------                                  
impose no obligation upon the Participant to exercise such Option.

          (m) Other Provisions: The Option agreements authorized under this Plan
              ----------------                                                  
shall contain such other provisions, including, without limitation, restrictions
upon the exercise of the Options, as the Board shall deem advisable.  Shares
shall not be issued pursuant to the exercise of an Option, if the exercise of
such Option or the issuance of shares thereunder would violate, in the opinion
of legal counsel for the Corporation, the provisions of any applicable law or
the rules or regulations of any applicable governmental or administrative agency
or body, such as the Revenue Code, the Act, the Securities Exchange Act of 1934,
the rules promulgated under the foregoing or the rules and regulations of any
exchange upon which the shares of the Corporation are listed.  Without limiting
the generality of the foregoing, the exercise of each Option shall be 

                                      -6-
<PAGE>
 
subject to the condition that if at any time the Corporation shall determine
that (i) the satisfaction of withholding tax or other similar liabilities, or
(ii) the listing, registration or qualification of any shares covered by such
exercise upon any securities exchange or under any state or federal law, or
(iii) the consent or approval of any regulatory body, or (iv) the perfection of
any exemption from any such withholding, listing, registration, qualification,
consent or approval is necessary or desirable in connection with such exercise
or the issuance of shares thereunder, then in any such event, such exercise
shall not be effective unless such withholding, listing registration,
qualification, consent, approval or exemption shall have been effected, obtained
or perfected free of any conditions not acceptable to the Corporation.

7.   Effectiveness of Plan; Expiration
     ---------------------------------

     This Plan shall be deemed effective as of September 19, 1996 and shall
expire on August 31, 2001 but such expiration shall not affect the validity of
outstanding Options.

8.   Amendment and Termination of the Plan
     -------------------------------------

     The Board may, insofar as permitted by law, from time to time, with respect
to any funds not reserved for outstanding bonus grants or any shares at the time
not subject to Options, suspend or terminate the Plan or revise or amend it in
any respect whatsoever; provided, however, no such action shall alter or impair
the rights and obligations under any bonus agreement or Option then outstanding
as of the date thereof without the written consent of the Participant
thereunder.  No bonus nor Option may be granted while the Plan is suspended or
after it is terminated, but the rights and obligations under any bonus agreement
or Option granted while the Plan is in effect shall not be impaired by
suspension or termination of the Plan.

9.   Indemnification of Board
     ------------------------

     In addition to such other rights or indemnifications as they may have as
executive officers or otherwise, and to the extent allowed by applicable law,
the members of the Board and the Committee shall be indemnified by the
Corporation against the reasonable expenses, including attorneys' fees, actually
and necessarily incurred in connection with the defense of any claim, action,
suit or proceeding, or in connection with any appeal thereof, to which they or
any of them may be a party by reason of any action taken, or failure to act,
under or in connection with the Plan or any bonus or Option granted thereunder,
and against all amounts paid by them in settlement thereof (provided such
settlement is approved by independent legal counsel selected by the Corporation)
or paid by them in satisfaction of a judgment in any such claim, action, suit or
proceeding, except in any case in relation to matters as to which it shall be
adjudged in such claim, action, suit or proceeding that such Board member is
liable for negligence or misconduct in the performance of his or her duties;
provided that within sixty (60) days after institution of any such action, suit
or Board proceeding the member involved shall offer the Corporation, in writing,
the opportunity, at its own expense, to handle and defend the same.

       made to the Plan, or the discontinuance or abandonment of the Plan.

    D. Cautionary Statement

       It is important that you complete the Adoption Agreement with great care.
       Failure to fill out the Adoption Agreement properly may result in
       disqualification of the Plan.

    E. Reliance on Opinion Letter

       The adopting Company may not rely on an opinion letter issued by the
       National Office of the Internal Revenue Service, or a notification letter
       issued by a Key District Office, as evidence that the Plan is qualified
       under Code Section 401. To obtain reliance with respect to Plan
       qualification, the Company must apply to the appropriate Key District
       Office for a determination letter. This Adoption Agreement may be used
       only in conjunction with basic plan document No. 01.

Account:  The Participant 401(k) Account and/or Employer Contribution Account.

Account Balance:  The value of an Account determined as of any Valuation Date.

Administrative Committee:  The committee appointed under, and having the 
responsibilities specified in, Articles VII and VIII.

Adoption Agreement:  The instrument executed by the Company by which it agrees 
to adopt the Plan.  The Adoption Agreement contains all the options that the 
Company may select under the Plan and is an integral part of the Plan.

Affiliate:  Any corporation, partnership, or other entity (other than the 
Company) which is:

(a) a member of a "controlled group of corporations" (as defined in Code Section
    414(b)) of which the Company is a member;
(b) a member of any trade or business under "common control" (as defined in Code
    Section 414(c)) with the Company;
(c) a member of an "affiliated service group" (as defined in Code Section 
    414(m)) which includes the Company;
(d) a "leasing organization" which "leases" (as defined in Code Section 414(n))
    its employees to the Company and which otherwise satisfies the requirements
    of Code Sections 414(n)(I) through (4) and which employees who are so leased
    to the Company are (i) not covered by a money purchase pension plan
    providing (A) a nonintegrated employer contribution rate of at least 10% of
    compensation as defined in Code Section 415(c)(3) (but including amounts
    contributed under a salary reduction agreement which are excludable from the
    Employee's gross income under Code Sections 125, 402(a)(8), 402(h), or
    403(b)), (B) immediate participation (other than an individual whose
    compensation from the leasing organization in each Plan Year during the 4-
    year period ending with the Plan Year is less than $1,000), and (C) full and
    immediate vesting or (ii) if covered by such a money purchase pension plan,
    constitute more than 20% of the Company's non-highly compensated workforce
    within the meaning of Code Section 414(n)(5)(C)(ii); or
(e) an entity described in regulations promulgated by the Secretary of the 
    Treasury under Code Section 414(o).

Beneficiary:  Any person, trust, estate, or charitable organization designated 
or deemed designated by a Participant to receive payment of Plan benefits due 
after the Participant's death, except to the extent the designation or deemed 
designation is superseded by a state statute which is not preempted by ERISA.

Benefit Commencement Date:  The first day on which all events have occurred 
which entitle the Participant or Beneficiary to a Plan benefit.

Board of Directors:  The Company's board of directors or other governing body.

Code:  The Internal Revenue Code of 1986, as amended from time to time.  
Reference to a specific Code provision includes any valid regulation promulgated
under that provision.

Company:  The entity that executes the Adoption Agreement, and any of its 
successors.

Compensation:  The compensation paid to a Participant during a Plan Year, as 
reflected on the Form W-2 filed by the Employer with respect to the Participant 
for the Plan Year, and includes Employer contributions made pursuant to a salary
reduction agreement which are not includible in the Participant's gross income 
under Code Section 125, 402(a)(8), 402(b), or 403(b).  However, except for 
determining the Actual Deferral Percentage and the Contribution Percentage under
Appendix A, and except for computing the minimum contribution under Appendix C
if the Plan becomes top-heavy, the Company may elect in Section III. A of the
Adoption Agreement to exclude overtime, bonuses, commissions, severance pay,
and/or other extraordinary remuneration.
  For any Self-Employed Individual, Compensation means Earned Income.
  Compensation is determined from the Employer's records.
  A Participant's Compensation may not exceed $200,000 (as adjusted at the same 
time and in the same manner as under Code Section 415(d)).  In determining the 
Compensation of a Participant under this limitation, the family aggregation 
rules of Code Section 414(q)(6) apply.  However, in applying those rules, 
"family" includes 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, by applying the family aggregation rules, the adjusted $200,000 limitation 
would be exceeded,


                                      -1-
<PAGE>
 
then the limitation is prorated among the affected individuals in proportion to
each individual's Compensation as determined before the application of the
$200,000 limitation.

Determination Year:  The period for which Highly Compensated Employees are being
identified.  If the Plan Year is a calendar year, the Plan Year is the 
Determination Year.  Otherwise, the months in the Plan Year which follow the 
Look-back Year are the Determination Year.

Early Retirement Age:  Age 55.

Earned Income:  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 are 
determined without regard to items not included in gross income and the 
deductions allocable to those items.  Net earnings are reduced by contributions 
by an Employer to a qualified plan to the extent deductible under Code Section 
404.  Earned Income is determined with regard to the deduction allowed by Code 
Section 164(f) for taxable years beginning after December 31, 1989.

Effective Date:  The date designated in Section I.B.3 of the Adoption Agreement 
as the date on which the Plan, as originally adopted or as amended and restated,
will apply.

Elective Deferrals:  Employer contributions made to the Plan under Participant 
401(k) Elections.

Eligible Employee:  All Employees of an Employer, except nonresident aliens with
no earned income from the Company or an Affiliate which constitutes United 
States source income and those employees in the job classifications specified in
Section II.A of the Adoption agreement.

  The Eligible Employees of a Participating Affiliate are those Employees 
designated as eligible for the Plan by the Participating Affiliate under 
Section 10.8.1.

Employee:  All common law or contract employees employed by the Company or an 
Affiliate.  Employee also includes leased employees within the meaning of Code 
Section 414(n)(2).  However, if the leased employees constitute less than 20% of
the Employer's non-highly compensated work force within the meaning of Code 
Section 414(n)(1)(C)(ii), Employee does not include leased employees covered by 
a plan described in Code Section 414(n)(5) unless otherwise provided by this 
Plan.

Employer:  The Company or Participating Affiliate by whom an Employee is 
employed.

Employer Contribution Account:  The account under the Plan established for a 
Participant under Section 3.5.2.

Employment:  An Employee's employment with the Company or an Affiliate.  An 
Employee will not have terminated Employment while on a leave of absence for 
required military service or on a leave of absence for any other purpose 
authorized in writing by the Company or an Affiliate under uniform and 
nondiscriminatory rules if the Employee completes an Hour of Service with the 
Company or an Affiliate within 90 days after his separation from military 
service or within 90 days after the expiration of his other leave of absence.  
If the Employee does not complete an Hour of Service during the 90-day period, 
the Employee will be deemed to have terminated Employment as of the first day of
his leave of absence.

Entry Date:  The first day of any month.

ERISA:  The Employee Retirement Income Security Act of 1974, as amended from 
time to time.  Reference to a specific provision of ERISA includes any valid 
regulation promulgated under that provision.

Family Member:  An individual described in Code Section 414(q)(6)(B); namely, 
the spouse of an Employee, the lineal ascendants of an Employee, the lineal
descendants of an Employee, the spouses of lineal ascendants of the Employee,
and the spouses of lineal descendants of the Employee. Under this definition,
Employee refers only to a 5-percent owner of the Company or a top ten Highly
Compensated Employee.

Highly Compensated Employee:  An individual described in Code Section 414(q), 
including both Highly Compensated active Employees and Highly Compensated former
Employees.  A Highly Compensated active Employee is an Employee who performs 
service for an Employer during the Determination Year and who, during the 
Look-Back Year (a) received Compensation in excess of $75,000 (as adjusted under
Code Section 415(d)), (b) received Compensation from an Employer in excess of
$50,000 (as adjusted under Code Section 415(d)) and was a member of the top-paid
group for that year, or (c) was an officer of an Employer and received 
Compensation during that year that is greater than 50% of the dollar limitation 
in effect under Code Section 415(b)(1)(A).  Highly Compensated active Employees 
also include (a) an Employee who is described in the preceding sentence if the 
term "Determination Year" is substituted for the term "Look-Back Year" and who 
is one of the 100 Employees who received the most Compensation from the Employer
during the Determination Year, and (b) an Employee who is a 5-percent owner at 
any time during the Look-Back Year or Determination Year.

   The highest paid officer for a year is treated as a Highly Compensated 
Employee if no officer has Compensation in excess of 50% of the dollar 
limitation in effect under Code Section 415(b)(1)(A) during either a 
Determination Year or a Look-Back Year.

   A Highly Compensated former Employee includes any Employee who separated from
service (or was deemed to have separated) before the Determination Year, 
performs no service for an Employer during the Determination Year, and was a 
Highly Compensated active Employee for either the Determination Year during 
which he separated from service (or was deemed to have separated) or any 
Determination Year ending on or after the Employee's 55th birthday.

   The determination of who is a Highly Compensated Employee, including the 
determination of the number and identity of the Employees in the top-paid group,
the top 100 Employees, the number of Employees treated as officers, and the 
Compensation that is considered, is made in accordance with Code Section 414(q) 
and the following:

(a)  Leased Employees covered by a safe harbor pension plan are not treated as 
     Employees with respect to retirement plans.

(b)  In determining Compensation, accrued (not paid) compensation is not used
     and amounts other than wages, fees, bonuses, commissions, etc. are ignored
     in accordance with Treasury Regulation Section 1.415-2(d)(8).

(c)  The top-paid group is the highest paid 20% of the number of "Employees" 
     employed by the Employer during the testing year, excluding:

     (i)   nonresident aliens with no U.S. earned income;

     (ii)  leased Employees covered by a safe harbor pension plan who are not 
           treated as Employees;

     (iii) bargaining unit workers if this Plan excludes all bargaining unit
           workers and 90% or more of the Employer's work force consists of
           bargaining unit workers;

     (iv)  probationary Employees who have not completed 6 months of service;

     (v)   part time Employees who normally work fewer than 17.5 hours per week;

     (vi)  seasonal workers who normally work during less than 6 months in any 
           testing year; and

     (vii) Employees who have not attained age 21 in any testing period.

(d)  The simplified method for determining Highly Compensated Employees under 
     Code Section 414(q)(12) does not apply.

Hour of Service:

(a)  Each hour for which an Employee is paid, or entitled to payment, for the
     performance of duties for the Company or an Affiliate. These hours are
     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
     Company or an Affiliate 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 may be credited under this paragraph for any
     single continuous period (whether or not the period occurs in a single
     computation period). Hours under this paragraph are calculated and credited
     pursuant to section 2530.200b-2 of the Department of Labor Regulations
     which is incorporated by this reference; and

(c)  Each hour for which back pay, irrespective of mitigation of damages, is
     either awarded or agreed to by the Company or an Affiliate. The same Hours
     of Service are not credited both under paragraph (a) or paragraph (b), as
     the case may be, and under this paragraph (c). These hours are 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.

       If an Adoption Agreement allows an Employer to elect to determine an
     Employee's eligibility for participation based on months of service, an
     Employee will be credited with 190 Hours of Service for a month if the
     Employee would be credited with at least 1 Hour of Service during that
     month.

Investment Fund: An investment fund selected by the Administrative Committee 
under Section 8.5.

ending within the Plan Year.

Matching Contribution: An Employer contribution to the Plan for the benefit of a
Participant because of the Participant's Elective Deferral.

Nonelective Contributions: An Employer contribution to the Plan (other than a 
Matching Contribution or Qualified Matching Contribution) which the Participant 
could not have elected to receive in cash or as another taxable benefit.

Period of Severance: A period of at least 12 consecutive months beginning on the
later of (a) the date an Employee quits, retires, is discharged, or dies, or (b)
the first anniversary of the date that the Employee is absent from work (with or
without pay) for any other reason, and ending on the date he again becomes an 
Employee.  A Period of Severance is measured in years with each annual 
anniversary of the date on which the Period of Severance began measured as one 
year.

   However, a Period of Severance does not begin if the Participant is:
(a) on a leave of absence authorized by his Employer in accordance with standard
    personnel policies applied in a nondiscriminatory manner to all Employees
    similarly situated and returns to active Employment by an Employer within 90
    days after expiration of the leave of absence;
(b) on military leave while the Employee's reemployment rights are protected by
    law and returns to active Employment by an Employer within 90 days after his
    discharge or release (or such longer period as may be prescribed by law); or
(c) on layoff and returns to work within such period and in such a manner as to
    maintain seniority according to the rules of the Company in effect on the
    date of return.

       Solely,to determine whether a Period of Severance has occurred for
    participation and vesting purposes for a Participant who is absent from work
    for maternity or paternity reasons, the 24-consecutive month period
    beginning on the first anniversary of the first date of the absence is not a
    Period of Severance. However, the Participant is not credited for a Year of
    Service for the 12-month period between the first and second anniversaries
    of the absence. An absence from work for maternity or paternity reasons
    means an absence (a) because of the Participant's pregnancy, (b) because of
    the birth of the Participant's child, (c) because of the placement of a
    child with the Participant in connection with the Participant's adoption of
    the child, or (d) for caring for the child for a period beginning
    immediately after the birth or placement.

    conditions must be satisfied before a Rollover Contribution can be made:
(a) the transfer to the Plan must occur within 60 days after the Employee's 
    receipt of the last distribution from the other plan; and
(b) the amount transferred must equal any portion of the distribution the
    Employee received from the other plan, subject to the maximum rollover
    provision of Code Section 402(a)(5)(B), limiting the amount to the fair

periods begin with first Plan Year commencing after the date the Employee first 
performs an Hour of Service.

Years of Service: An Employee's period of service with the Company or an 
Affiliate. The Employee's Years of Service equals the sum of:

1.3 Rules of Construction
- -------------------------

     1.3.1 As used in this Plan, a pronoun or adjective in the masculine gender
includes the feminine gender and the singular includes the plural (and vice
versa), unless the context clearly indicates otherwise. Any reference to

                                      -5-
<PAGE>
 
Article, Section, Appendix, or paragraph means the Article, Section, Appendix, 
or paragraph so delineated in this Plan.

   1.3.2  The titles and headings to Articles, Sections, and Appendices are for 
convenience of reference. In case of any conflict, the text of the Plan, rather 
than the titles and headings, controls.


1.4 Controlling Law
- -------------------

   The Plan is intended to qualify under Code Section 401(a) and to comply with 
ERISA, and its terms will be interpreted accordingly. If any Plan provision is 
subject to more than one construction, the ambiguity will be resolved in favor 
of the interpretation or construction which is consistent with that intent. 
Similarly, in the event of any conflict between any provisions of the Plan or 
between any Plan provision and Beneficiary designation form or any other form 
submitted to the Administrative Committee, the Plan provisions necessary to 
retain qualified status under Code Section 401(a) will prevail. Otherwise, to
the extent not preempted by ERISA or as expressly provided, the laws of New
Jersey (other than its conflict of law provisions) will control the
interpretation and performance of the Plan.


1.5 Savings Clause
- ------------------

   Each Plan provision is independent of each other provision. If any provision 
proves, or is held by any court, or tribunal, board, or authority of competent 
jurisdiction, to be void or invalid as to any Participant or group of 
Participants, that provision will be disregarded and deemed to be void and no 
part of the Plan. However, the invalidation of any provision will not impair or 
affect this Plan or any other provision.

allocated to the Employer Contribution Account for all Participants or only for 
Non-Highly Compensated Employees. The allocation is made in the ratio that the 
Compensation paid to the Participant for whom the Nonelective Contribution is 
made bears to the total Compensation for the Plan Year of all Participants for 
whom the Contribution is made.

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

     3.2.1  A Participant 401(k) Election must be in 1% increments and cannot be

soon as practicable after discovery that portion of his Participant 401(k) 
Account attributable to the mistaken Rollover Contribution. The amount to be 
distributed will be determined as of the Valuation Date coincident with or 
immediately preceding the discovery.

     The Trustee may accept, only at the direction of the Administrative 
Committee, as part of the Trust a Transfer Contribution. The Administrative

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

  3.6.1  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 all plans established 
for the other trades or businesses must, when looked at as a single plan, 
satisfy Code Section 401(a) and (d) for the Employees of this and the other 
trades or businesses.

  3.6.2  If this Plan provides contributions and benefits for one or more 
Owner-Employees who control one or more other trades or businesses, the 
Employees of each other trade or business must be included in a plan which 
satisfies Code Section 401(a) and (d) and which provides contributions and 
benefits not less favorable than provided for the Owner-Employees under this 
Plan.

  3.6.3  If an individual is covered as an Owner-Employee under the plans of two
or more trades or businesses, then the contributions or benefits of the 
Employees under a plan of a trade or business which the Owner-Employee controls 
must be as favorable as those provided for the Owner-Employee under the most 
favorable trade or business which he does not control.

  3.6.4  An Owner-Employee is considered to control a trade or business if the 
Owner-Employee, either alone or with other Owner-Employees;

(a) owns the entire interest in an unincorporated trade or business; or

(b) in the case of a partnership, owns more than 50% of either the capital 
    interest or the profits interest in the partnership.

  An Owner-Employee is treated as owning any interest in a partnership which is 
owned, directly or indirectly, by another partnership controlled by the 
Owner-Employee, either alone or with other Owner-Employees.

4.1 Determination of Vesting
- ----------------------------

  4.1.1  A Participant has a nonforfeitable percentage of 100% at all times in 
the Account Balance of his Participant 401(k) Account.

  4.1.2  If the Company elects in Section V of the Adoption Agreement that 
Matching Contributions and Nonelective Contributions be immediately 100% 
nonforfeitable then Matching Contributions are Qualified Matching Contributions 
and Nonelective Contributions are Qualified Nonelective Contributions.  
Otherwise, a Participant has a nonforfeitable percentage in the Account Balance 
of his Employer Contribution Account determined as follows:
(a) 100%, if he terminates Employment (i) after attaining Normal Retirement Age 
    or (ii) because of death or disability; or
(b) in accordance with Section V of the Adoption Agreement, if he terminates 
    Employment for any other reason. 
  Under this Section, a disability is a physical or mental condition which 
results in the Participant becoming eligible for disability benefits under:
(a) the Employer's long term disability plan; or
(b) the Social Security Act, if the Employer does not maintain a long term 
    disability plan covering the Participant.


4.2 Rules for Crediting Vesting Service
- ---------------------------------------

  4.2.1  Unless otherwise elected in Section V of the Adoptation Agreement, all 
Years of Service are credited to determine a Participant's Vesting Service.
  4.2.2  An Employee's Vesting Service after a Period of Severance of at least 5
years is not counted in computing the nonforfeitable percentage in his Employer 
Contribution Account derived from contributions accrued before the Period of 
Severance.


4.3 Forfeitures
- ---------------

  4.3.1  The non-vested portion of the Employer Contribution Account of a 
Participant who has terminated Employment is forfeited as of the date on which 
he has a 5-year Period of Severance or, if earlier, upon distribution or deemed 
distribution of the Participant's entire Account Balance.
  4.3.2  If a Participant who has terminated Employment elects to have 
distributed less than the entire nonforfeitable portion of his Employer 
Contribution Account, the non-vested portion that is forfeited 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 denominator 
of which is the total value of the nonforfeitable portion of his Employer 
Contribution Account.  The forfeiture will be used to reduce Employer 
Contributions.  The forfeiture will be restored, however, if the Participant 
returns Employment as an Eligible Employee and the Participant repays to the 
Plan the full amount of the distribution attributable to his Employer 
Contribution Account before the earlier of 5 years after the first date on which
the Participant is subsequently reemployed by an Employer, or the date the 
Participant incurs a 5-year Period of Severance following the date of 
distribution.  For a Participant who has been deemed to have received a 
distribution, the forfeiture will be restored, upon reemployment, to the amount 
on the date of the deemed distribution, if the Participant returns to Employment
as an Eligible Employee before the Participant incurs a 5-year Period of 
Severance.

                    Amount and Payment of Account Balances

5.1 Termination of Employment
- -----------------------------

   Upon termination of Employment, a Participant shall receive, subject to the 
rules described below, the sum of: 

(a)  the Account Balance of his Employer Contribution Account as of the
     Valuation Date coincident with or immediately after the date the
     Participant terminates Employment, multiplied by his nonforfeitable
     percentage determined under Article IV; and

(b)  the Account Balance of his Participant 401(k) Account as of that Valuation 
     Date.


5.2 Payment of Account Balances on Termination of Employment
- ------------------------------------------------------------

   5.2.1  If the nonforfeitable portion of a Participant's Account Balances as
of the Valuation Date coincident with or immediately after the termination of
Employment is not more than $3,500, the nonforfeitable portion of the Account
Balances will be paid in a lump sum as soon as practicable thereafter.

   5.2.2  If the nonforfeitable portion of a Participant's Account Balances as
of the Valuation Date coincident with or immediately after termination of
Employment is more than $3,500, the Administrative Committee shall notify the
Participant of the right to defer payment of the nonforfeitable portion. The
notification must describe the material features and, if applicable, explain the
relative values of the optional forms of payment available under the Plan in a
manner that would satisfy the notice requirements of Code Section 417(a)(3). The
notification must be provided not less than 30 or more than 90 days before the
Benefit Commencement Date. The nonforfeitable portion of the Participant's
Account Balances will be distributed as soon as practicable after the
Participant elects to receive the distribution, but not later than the close of
the Plan Year in which the Participant attains Normal Retirement Age.

   5.2.3  A Participant is deemed to have received a distribution if the 
nonforfeitable percentage in his Employer Contribution Account is 0% on 
termination of Employment.


5.3 Death Benefit
- -----------------

   5.3.1  The benefit payable to a Beneficiary on the death of a Participant 
before the commencement of benefits equals the sum of the Participant's Account 
Balances as of the Valuation Date coincident with or immediately after the date 
of the Participant's death. The benefit payable to a Beneficiary on the death of
a Participant after distribution of his interest has begun, but before 
distribution has been completed, equals the remaining portion of the 
Participant's interest. The Beneficiary will be paid the benefit in a lump sum 
within 90 days after the Administrative Committee has been notified of the 
Participant's death unless payment is impracticable or the Beneficiary cannot be
located.


5.4 Beneficiaries
- -----------------

   5.4.1  Each Participant shall designate one or more direct or contingent 
Beneficiaries to receive any amounts which may become payable under the Plan 
upon the Participant's death. A Participant's designation of a Beneficiary must 
be filed with the Administrative Committee on a form provided by the 
Administrative Committee.

   5.4.2  Any designation of a Beneficiary may be revoked by filing a later 
designation or an instrument of revocation with the Administrative Committee in 
a time and manner designated by the Administrative Committee. The last 
designation received by the Administrative Committee is controlling over any 
testamentary or other disposition. However, no designation, or change or 
cancellation of a designation, is effective unless received by the 
Administrative Committee before the Participant's death, and in no event may it 
be effective as of a date before receipt.

   5.4.3  A married Participant's spouse must consent to a designation of a 
Beneficiary other than the spouse. The spouse's consent to the designation must 
be witnessed by a notary public or by a Plan representative and is effective 
only with respect to the Beneficiary or Beneficiaries specified in the 
designation (unless the consent expressly provides that the designation may be 
changed without further consent from the spouse). If the Participant establishes
to the satisfaction of a Plan representative that written consent cannot be
obtained because there is no spouse or the spouse cannot be located, the
designation will be deemed effective. In addition, if the spouse is legally
incompetent to give consent, then the spouse's legal guardian, even if the
guardian is the Participant, may give consent. If a Participant is legally
abandoned or has been separated (under the state law of the Participant's

                                     -11-
<PAGE>
 
residence) and the Participant has a court order to that effect, spousal
consent is not required unless a Qualified Domestic Relations Order provides
otherwise. Any consent necessary under this provision is valid only with respect
to the spouse who signs the consent. A Participant may revoke a prior waiver
without the consent of the spouse at any time before the commencement of
benefits. The number of revocations is not limited.

   5.5.4 If a Participant is not married and fails to designate a Beneficiary,
or if no designated Beneficiary survives the Participant, any amounts due after
the Participants death will be paid to his then living issue, per stirpes, but
if the Participant is not survived by issue, then to the legal representative of
his estate in a single lump sum.

   5.4.5  Subject to any Qualified Domestic Relations Order procedures as may be
established, if at any time any doubt exists about the right of any person to 
any payment under the Plan, or about the amount or time of the payment, the 
Administrative Committee may direct the Trustee to (a) hold the sum as 
segregated amount in trust until the right, amount, or time is determined or 
until there is an order of a court of competent jurisdiction, (b) pay the sum 
into court in accordance with appropriate rules of law in such case then 
provided, or (c) pay the sum only upon receipt of a bond or similar 
indemnification (in such amount and in such form as is satisfactory to the 
Administrative Committee).
   5.4.6  If a period certain distribution is elected, and a Beneficiary dies 
after the death of the Participant but before distribution of the Participant's 
entire Account Balances, then the remainder is paid to the estate of the 
Beneficiary.
  5.4.7  No Beneficiary has any rights to benefits under the Plan unless he 
survives the Participant.
  5.4.8  A Participant's former spouse is treated as his spouse to the extent
provided under a Qualified Domestic Relations Order.
  5.4.9  If the Participant and his Beneficiary die so that it is not possible 
to determine who died first, it is presumed that the Participant survived the 
Beneficiary.

5.5 Limitation on Commencement of Benefits
- ------------------------------------------

   5.5.1  A Participant must begin to receive his benefits no later than the 
60th day after the close of the Plan Year in which the latest of the following 
occurs:
(a)  the Participant attains Normal Retirement Age;
(b)  the 10th anniversary of the year in wich the Participant commenced 
participation; or
(c)  the Participant terminates Employment.
   If the amount of benefits payable cannot be determined within the 60-day
period, or if it is not possible to pay the benefits within that period because
the Administrative Committee has been unable to locate the Participant after
making reasonable efforts to do so, then a payment, retroactive to the 60th day,
will be made no later than 60 days after the earliest date on which the amount
of the benefits can be determined or the Participant can be located, as the case
may be.
   5.5.2  In addition, a Participant must begin to receive his benefits no later
than the first day of April following the calendar year in which he attains age 
70 1/2.  All distributions under this Plan must be made in accordance with 
Appendix D.

5.6 Withdrawals Before Termination of Employment
- ------------------------------------------------

   5.6.1  Each Participant who has attained age 59 1/2 may withdraw, as of the 
Valuation Date immediately preceding the filing of an application with the 
Administrative Committee, all or any part of the nonforfeitable portion of his 
Account Balances.
   5.6.2 Each Participant who has not attained age 59 1/2 may make a hardship
withdrawal from his Participant 401(k) Account if he demonstrates to the
Administrative Committee that the withdrawal is necessitated by the
Participant's immediate and heavy financial need and the Participant lacks the
available resources. A hardship withdrawal may not exceed the amount of the
immediate and heavy financial need and is limited to the Participant's Elective
Deferrals, Rollover Contributions, and Transfer Contributions and may not
include amounts treated as Elective Deferrals under Section A.4.
   5.6.3  A distribution is deemed to be made on account of an immediate or 
heavy financial need of the Participant only if the distribution is on account 
of:
(a)  medical expenses described in Code Section 213(d), incurred by the
     Participant, Participant's spouse, or any dependents of the Participant
     (within the meaning of Code Section 152);


                                     -12-
<PAGE>
 
(b)  purchase (excluding mortgage payments) of a principal residence for the 
     Participant;
(c)  payment of tuition for the next semester or quarter of post-secondary 
     education for the Participant, his spouse, children, or dependents; or
(d)  the need to prevent the eviction of the Participant from his principal
     residence or foreclosure on the mortgage of the Participant's principal
     residence.
  5.6.4  Before receiving a hardship withdrawal, a Participant must obtain all 
distributions and all nontaxable loans under all plans maintained by the Company
or an Affiliate.
  5.6.5  A Participant who receives a hardship withdrawal is suspended from 
making any Elective Deferrals for 12 months after receiving the distribution. 
The maximum amount of Elective Deferrals for the Participant's taxable year 
after the taxable year of the hardship withdrawal is the dollar limit under 
Section A.2 less the amount of the Participant's Elective Deferrals for the 
taxable year of the hardship withdrawal.
  5.6.6  The minimum hardship withdrawal is $500.
  5.6.7  The Adminstrative Committee shall establish rules and procedures with 
respect to any withdrawal, including (a) the requirements for requesting and 
receiving the hardship withdrawals and (b) suspension from further Elective 
Deferrals.


5.7 Loans
- ---------

  5.7.1  A Participant may submit an application to borrow from his Participant 
401(k) Account and Employer Contribution Account (on such terms and conditions 
as the Administrative Committee may prescribe). The amount of the loan may not 
exceed the lesser of: (a) $50,000 reduced by the excess (if any) of the highest 
outstanding balance of all other loans from the Plan during the one-year period 
ending on the date on which the loan was made, over the outstanding balance of 
loans from the Plan on the date on which the loan was made or (b) 50% of the sum
of the Account Balance in his Participant 401(k) Account and the nonforfeitable 
portion of the Account Balance in his Employer Contribution Account on the 
Valuation Date coincident with or immediately preceding the filing of the loan 
application with the Administrative Committee.
  5.7.2  If approved, each loan must comply with the following conditions:
(a)  it must be evidenced by a negotiable promissory note;
(b)  the rate of interest payable on the unpaid balance of the loan must equal
     the prevailing interest rate charged by a bank for a secured personal loan,
     but may not exceed the rate that may be imposed by the state's usury law,
     if violation of that law subjects the violator to criminal sanctions;
(c)  the loan, by its terms, must be entirely repaid within 5 years;
(d)  the loan must be secured by the Participant's interest in his Account
     Balances and such additional collateral as the Administrative Committee may
     from time to time consider prudent;
(e)  the loan must be repaid with respect to both principal and interest in
     substantially equal payments over the life of the loan, with payments not
     less frequently than quarterly;
(f)  the minimum loan under the Plan will be $500;
(e)  no more than one loan may be outstanding at any time; and
(h)  in the event of the Participant's termination from Employment, the 
     remaining payments on the loan will be due immediately.
  The level amortization requirement in paragraph (e) does not apply to a period
when a Participant is on leave of absence without pay for up to one year. 
Nothing in the Plan precludes repayment or acceleration of the loan before the 
end of the commitment period or the use of a variable interest rate under 
paragraph (b).
  5.7.3  If a Participant is granted a loan, the Administrative Committee shall 
establish a "loan account" for the Participant. The Trustee shall hold all loan 
accounts as part of the Trust. The Trustee shall transfer the amount of the loan
to the loan account from the Participant 401(k) Account and Employer 
Contribution Account on a pro rata basis. The amounts transferred shall be 
                          --- ----
withdrawn from the Investment Funds in accordance with rules established by the 
Administrative Committee. The Trustee shall deposit the promissory note executed
by the Participant in his loan account. For purposes of the Plan, the promissory
note is deemed to have a fair market value at any given time equal to the unpaid
balance of the note plus accrued but unpaid interest.
  5.7.4  Principal and interest payments of a Participant's loan are credited 
initially to that Participant's loan account and are transferred as soon as 
reasonably practicable to the Participant's Accounts from which the loan amount
was originally withdrawn on a pro rata basis. The amounts transferred are 
                              --- ----  
reinvested in the Investment Funds in accordance with rules established by the 
Administrative Committee.
  5.7.5  Any loss caused by nonpayment or other default on a Participant's loan 
obligations is borne solely by the Participant's loan account. The the extent 
permissable at law, in the event of a default, foreclosure on the promissory 
note and attachment of security will not occur until an event occurs that would 
allow or require a distribution of a Participant's Account Balances.

                                     -13-

<PAGE>
 
  5.7.6  All fees and expenses incurred in connection with a Participant's loan 
obligation are borne solely by the Participant's loan account.

  5.7.7  The Administrative Committee shall make loans available to all 
Participants and Beneficiaries who are parties in interest with respect to the 
Plan within the meaning of ERISA Section 3(14).

  5.7.8  Loans may not be made available to Highly Compensated Employees in an 
amount greater than that available to other Employees.

  5.7.9  A Participant's loan request will be cancelled if the Participant dies 
before the loan amount requested is actually distributed.

  5.7.10 No loans may be made available to any shareholder-employee or 
Owner-Employee unless the Plan receives an exemption from the Department of 
Labor for such loan which exemption is received wholly at the Employee's 
expense.  A shareholder-employee is an employee or officer of an electing small 
business (Subchapter S) corporation who owns (or is considered as owning under 
Code Section 318(a)(1)), on any day during the taxable year of the Corporation,
more than 5% of the outstanding stock of the Corporation.


5.8 Additional Distribution Events
- ----------------------------------

  In addition to the other distribution events set forth in this Article and 
Appendix A, a Participant is eligible to receive a distribution from the Plan, 
either total or partial, upon the occurrence of any of the following events:

(a) termination of the Plan without the establishment of another defined 
    contribution plan;

(b) 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 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

(c) 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.

6.1 Normal Form of Payment
- --------------------------
    The normal form of payment is a lump sum benefit.

6.2 Optional Form of Payment
- ----------------------------
    The only optional form of payment is in installments over a period certain.

are to be paid. Each participant may elect in writing not to take the normal 
form of payment and to elect the optional form of payment. The election period 
is the 90-day period ending on the Participant's Benefit Commencement Date. The 
Administrative Committee may, on a uniform and nondiscriminatory basis, provide 
for other periods that comply with regulations issued under Code Section 
401(a)(11) and Code Section 417.
    6.3.2 A Participant may revoke an election to take an optional form of 
payment, and elect the normal form of payment, at any time during the election 
period.

6.4 Limitation on Options
- -------------------------
    A Participant or a Beneficiary may not elect to receive benefits in either 
of the following forms:
(a)  a benefit in such form that, as of the time payment commences, the present
     value of the benefits payable to the Participant or Beneficiary is less
     than 50% of the total benefits payable or that would violate the incidental
     death benefit rule; or
(b)  a benefit in such form that all or any portion of the value of the benefit
     otherwise payable to the Participant during his lifetime is either (i) paid
     instead to his Beneficiary or (ii) set aside for payment to his survivor at
     death.

6.5  Change in the Form or Timing of Payment
- --------------------------------------------
    Any Participant or Beneficiary whose payments are being deferred or who is
    receiving installment payments may request acceleration or other
    modification of the form of distribution.

6.6  Conditions to Distribution
- ------------------------------
    Before any distribution is made, the Participant or Beneficiary must furnish
the Administrative Committee with all applications, certificates, tax waivers, 
signature guarantees, and any other documents which the Administrative Committee
considers necessary or advisable.

  A named fiduciary, and any fiduciary appointed by a named fiduciary, may
employ one or more persons to render advice with regard to any responsibility of
the named fiduciary or fiduciary under the Plan.

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

  Any fiduciary may serve in more than one fiduciary capacity with respect to
the Plan.



7.4 Payment of Expenses
- -----------------------

commissions, service charges, loan expenses, and professional fees.

  7.4.2  All other Plan expenses, including expenses of the Administrative
Committee and the Trustee, to the extent permitted by law, are paid by the
Trust. However, an Employer may elect to pay these expenses.



7.5 Indemnification

  To the extent not prohibited by state or federal law, the Company or an
Affiliate will indemnify and hold harmless any named fiduciary or any other
Employee, officer, or director of the Company or an Affiliate from all claims
for liability, loss, or damage (including payment of expenses in connection with
defense against any claim) which result from any exercise or failure to exercise
any responsibilities with respect to the Plan, other than willful misconduct or
willful failure to act.

                              Plan Administration


8.1 Administrative Committee
- ----------------------------

  8.1.1  Unless the Board of Directors otherwise provides, any member of the 
Administrative Committee who is an Employee of the Company or an Affiliate when 
appointed will be considered to have resigned from the Administrative Committee 
when no longer an Employee. Employees of the Company or an Affiliate may receive
no compensation for their services rendered to or as members of the 
Administrative Committee.
  8.1.2  The Administrative Committee shall act by a majority of its members at 
the time in office and any action may be taken either by a vote at a meeting or 
in writing without a meeting. However, if less than three members are appointed,
the Administrative Committee shall act only upon the unanimous consent of its 
members. The Administrative Committee may authorize in writing any person to 
execute any document or documents on its behalf. Any interested person, upon 
receipt of notice of the authorization directed to it may accept and rely on any
document executed by the authorized person until the Administrative Committee 
delivers to the interested person a written revocation of the authorization.
  8.1.3  A member of the Administrative Committee who is also a Participant may 
not vote or act upon any matter relating to himself.


8.2 Powers and Duties of the Administrative Committee
- -----------------------------------------------------

the Plan and determine all questions of fact or interpretation that may arise. 
Any construction or determination is conclusively binding on all persons 
interested in the Plan.

its expenses, as the Board of Directors and the Trustee agree upon from time to 
time; provided, however, that no compensation may be paid to any person who is 
an Employee.


8.5 Investment of Accounts 
- --------------------------

  8.5.1 It is intended that the Plan meet the requirements of ERISA Section 
404(c). In this regard, the Trustee, with the approval of the Administrative 
Committee, shall establish, or terminate, Investment Funds for the investment of
a Participant's Accounts. Each Investment Fund shall have the investment 
objective or objectives as established by the Trustee in accordance with ERISA 
Section 404(c). The Trustee's selection of Investment Funds must comply with the
following rules:

(a)  no assets of the Trust, excluding assets which have been invested in an
     Investment Fund, shall be invested in any security issued by the Company
     or any affiliate of the Company;

(b)  each Investment Fund shall limit investment in any security issue by any
     Company which establishes a plan using the Sponsor's prototype documents or
     by any affiliate of any such Company to the extent required for the
     exemption contained in Section 3(a)(2) of the Securities Act of 1933, as
     amended, to be available with respect to the plan and the interests
     therein; and

(c)  each Investment Fund shall, to the extent required to satisfy the
     requirements of ERISA Section 404(c), prohibit investment in any security
     issued by any Company which establishes a Plan using the Sponsor's
     prototype documents or by any affiliate of any such Company.

  8.5.2 The Trustee shall adopt rules and procedures for the Investment Funds in
accordance with ERISA Section 404(c) that, among other things, (a) allow
Participants to determine the portion of their Accounts that will be invested
in each Investment Fund and (b) determine what transfers between Investment
Funds will be allowed.


8.6 Valuation of Accounts
- -------------------------

  A Participant's Accounts are revalued at fair market value on each Valuation 
Date. On that date, the earnings and losses of the Investment Funds are 
allocated in the ratio that the portion of the Participant's Account Balances 
invested in a particular Investment Fund bears to the total amount invested in 
that Investment Fund. The Trustee shall adopt rules and procedures for valuing a
Participant's Account Balances and allocating earnings and losses of the 
Investment Funds.

                         Plan Amendment or Termination

9.1 Plan Amendment
- ------------------

  9.1.1  The Sponsor may amend any part of the Plan at any time including 
retroactive amendments necessary to assure that the Plan qualifies or continues 
to qualify under the Code, Regulations, Revenue Rulings, and any other 
guidelines published by the Internal Revenue Service. The Sponsor shall provide 
written notice of any amendment to the Company.

  9.1.2  The Company may at any time amend the choice of options in the Adoption
Agreement, by an instrument in writing, effective retroactively or otherwise.

  9.1.3  The Company may at any time amend the Plan by adding overriding 
language to the Adoption Agreement where the language is necessary to satisfy 
Code Sections 415 or 416 because of the required aggregation of multiple plans 
under those sections.

  9.1.4  The Company also may at any time amend the Plan by adding model 
amendments published by the Internal Revenue Service and which specifically 
provide that their adoption will not cause the Plan to be treated as 
individually designed.

  9.1.5  In accordance with the preceding provisions, the Company shall give the
Sponsor an executed copy of any amendment to the Adoption Agreement or the Plan.

  9.1.6  Except for amendments described in this Section, a Company that amends 
any portion of this Plan and its Adoption Agreement (other than to change the 
choice of options) will be deemed to have adopted an individually designed plan.
In addition, the Sponsor may deem any amendment described in Sections 9.1.3 and 
9.1.4 as causing the Plan to be treated as an individually designed plan, and 
the Company will no longer be an adopting employer of the Sponsor's "prototype 
plan" (as defined in Section 3.02 of Rev. Proc. 89-9).


9.2 Limitations on Plan Amendment
- ---------------------------------

  9.2.1  No Plan amendment, including the revision of any option selected in the
Adoption Agreement or the adoption of a new "prototype plan" (as defined in 
Section 3.02 of Rev. Proc. 89-9), may:

(a)  authorize any part of the Trust to be used for, or diverted to, purposes
     other than for the exclusive benefit of Participants or their
     Beneficiaries;

(b)  increase the duties or liabilities of the Trustee or affect the Trustee's 
     fees for services, unless the Trustee consents in writing;

(c)  decrease the accrued benefits of any Participant or Beneficiary under the 
     Plan except to the extent permissible under Code Section 412(c)(8); 

(d)  eliminate an optional form of benefit of any Participant or Beneficiary for
     the payment of Account Balances attributable to Employment before the
     amendment, except to the extent permissible by law;

(e)  reduce the nonforfeitable percentage of any Employee who is a Participant 
     as of the date the amendment is (i) adopted or if later, (ii) effective; or

(f)  change the vesting schedule, unless each Participant having not less than 3
     years of Vesting Service is permitted to elect, within a reasonable period
     specified by the Administrative Committee after the adoption of the
     amendment, to have his nonforfeitable percentage computed without regard to
     the amendment. However, no election need be provided to any Participant
     whose nonforfeitable percentage under the Plan, as amended, at any time
     cannot be less than the percentage determined without regard to the
     amendment.

  9.2.2  The period during which the election may be made will commence with the
date the amendment is adopted and end as 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 by the 
     Administrative Committee.


9.3 Right of the Company to
    Terminate Plan or Discontinue Contributions
- -----------------------------------------------

  The Company has the bona fide intention and expectation that from year to year
it will be able to and will consider it advisable to continue this Plan in 
effect and to make contributions. However, the Company reserves the right to 
terminate the Plan with respect to its Employees at any time by an instrument in
writing delivered to the Administrative Committee or to completely discontinue 
its contributions at any time.

                                     -19-
<PAGE>
 
9.4 Effect of Partial or Complete Termination
    or Complete Discontinuance of Contributions
- -----------------------------------------------

  9.4.1  As of the date of a partial termination of the Plan no further 
contributions or allocations of forfeitures will be made after that date with 
respect to each affected Participant, and each affected Participant who is then 
an Employee will become 100% vested in his Employer Contribution Account.

  9.4.2  As of the date of the complete termination of the Plan, or the complete
discontinuance of contributions under the Plan:

(a)  no further contributions or allocations of forfeitures will be made after 
     that date;

(b)  no Employee may become a Participant after that date; and

(c)  each Participant who is then an Employee will become 100% vested in his 
     Employer Contribution Account.

  9.4.3  All other provisions of the Plan will remain in effect unless otherwise
amended.



9.5 Distribution Upon Termination
- ---------------------------------

  As soon as administratively feasible after the date of termination of the 
Plan, the Participant's Account will, 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 Code Section 
4975(e)(7)) maintained by the Company or an Affiliate.



9.6 Bankruptcy
- --------------

  If the Company is at any time judicially declared bankrupt or insolvent 
without any provision being made for the continuation of this Plan, the Plan 
will be completely terminated in accordance with Section 9.4.2.



9.7 Action by Company
- ---------------------

  If the Company is a corporation, any action by the Company under this Plan 
must be by resolution of its Board of Directors, or by any person duly 
authorized by resolution of the Board to take the action.

  If the Company is a partnership, then any action by the Company must be by 
written action of any general partner, and if the Company is a self-employed 
business, then by its sole proprietor.

                           Miscellaneous Provisions

10.1 Exclusive Benefit of Participants
- --------------------------------------

  At no time may any part of the Trust (other than such part as is required to 
pay expenses) be used for, or diverted to, purposes other than for the exclusive
benefit of Participants or their Beneficiaries, except that, upon the direction 
of the Administrative Committee:

(a)  any contribution made by an Employer by a mistake of fact will be returned 
     by the Trustee within 1 year after the payment of the contribution;

(b)  any contribution made by an Employer will be returned by the Trustee within
     1 year after the denial of initial qualification of the Plan under Code 
     Section 401(a); and

(c)  any contribution made by an Employer will be returned by the Trustee to the
     extent disallowed as a deduction under Code Section 404 within 1 year after
     the disallowance.



10.2 Plan Not a Contract of Employment
- --------------------------------------

  The Plan is not a contract of Employment. The terms of Employment of any 
Employee are not affected in any way by the Plan or related instruments except 
as specifically provided therein.



10.3 Type of Plan
- -----------------

  The Plan is a profit sharing plan for purposes of Code Sections 401(a), 402, 
412, and 417.



10.4 Source of Benefits
- -----------------------

  Benefits under the Plan are paid or provided for solely from the Trust, and 
the Company, Participant Affiliates, and any fiduciary to the Plan assume no 
liability therefor. No Employee, Participant, former Participant, or Beneficiary
has any right to, or interest in, any assets of the Trust on termination of 
Employment or otherwise, except as specifically provided under the Plan.



10.5 Benefits Not Assignable
- ----------------------------

  Benefits provided under the Plan may not be assigned or alienated either 
voluntarily or involuntarily, except for loans as provided in Section 5.7 or as 
may otherwise by required by law. The preceding sentence also applies 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 the 
order is determined to be a Qualified Domestic Relations Order. The 
Administrative Committee has all powers necessary with respect to the Plan for 
the proper operation of Code Section 414(p) with respect to Qualified Domestic 
Relations Orders including, but not limited to, the power to establish all 
necessary or appropriate procedures, to authorize the establishment of new 
accounts with such assets and subject to such investment control by the 
Administrative Committee as the Administrative Committee may consider 
appropriate, and the Trustee may decide upon and make appropriate distributions 
therefrom.



10.6 Merger or Transfer of Assets
- ---------------------------------

  10.6.1  The merger or consolidation of an Employer with any other person, or 
the transfer of the assets of an Employer to any other person, or the merger of 
the Plan with any other plan will not constitute a termination of the Plan.

  10.6.2  The Plan may not merge or consolidate with, or transfer any assets or 
liabilities to, any other plan, unless each Participant would (if the Plan then 
terminated) receive a benefit immediately after the merger, consolidation, or 
transfer equal to or greater than the benefit he would have been entitled to 
receive immediately before the merger, consolidation, or transfer (if the Plan 
had then terminated).

                                     -21-
<PAGE>
 
10.7 Participation in the Plan by an Affiliate
- ----------------------------------------------

   10.7.1  With the Company's consent, any Affiliate, by appropriate action of 
its board of directors, a general partner, or the sole proprietor, as the case 
may be, may adopt the Plan. The Affiliate will determine the classes of its 
Employees eligible to participate in this Plan.

   10.7.2  A Participating Affiliate may terminate its participation in the Plan
with the Company's consent.

   10.7.3  A Participating Affiliate may withdraw from the Plan and the Trust 
with the Company's consent. The withdrawal will be deemed an adoption by the 
Participating Affiliate of a plan and trust identical to the Plan and the 
Trust, except that all references to the Company will be deemed to refer to the 
Participating Affiliate. At such time and in such manner as the Trustee directs,
the assets of the Trust allocable to Employees of the Participating Affiliate 
will be transferred to the trust deemed adopted by the Participating Affiliate.

   10.7.4  A Participating Affiliate has no power with respect to the Plan 
except as specifically provided in the Plan.

10.8 Conditional Adoption
- -------------------------

   The Company has adopted the Plan on the express condition that the Internal 
Revenue Service will consider it as initially qualifying under Code Section 
401(a) and the Trust qualifying for exemption from taxation under Code Section 
501(a). If the Internal Revenue Service determines that the Plan or Trust does 
not so qualify, the Plan may be amended or terminated as decided by the Company.
If the Plan is terminated, the Company may withdraw its contributions and the 
rights of all Employees will cease as if the Plan had never been adopted.

10.9 Inability to Locate Participant or Beneficiary
- ---------------------------------------------------

   If, after the exercise of due diligence by the Administrative Committee, a 
Participant or Beneficiary to whom Plan benefits are due cannot be located, the 
Trustee shall hold benefits as a segregated amount in trust for a period one 
month less than the relevant state escheat law to the extent that the escheat 
law is not preempted by ERISA. If not claimed by that date, the amount will be 
treated as a forfeiture and used to reduce future Employer contributions. 
However, if the Participant or Beneficiary is subsequently located and makes a 
claim for Plan benefits, the amount forfeited under the preceding sentence will 
be restored.

10.10 Application of Prior Plan
- -------------------------------

  The Plan benefit of any Participant who terminates Employment is determined in
accordance with the provisions of the Plan in effect on the date of the 
termination of Employment.

  Where the Plan constitutes a restatement and amendment of a predecessor plan
of the Company, that plan will be applied to the extent permitted by law in
determining the rights and duties of any persons with respect to any allocations
before the Effective Date.

10.11 Failure of Qualified Status
- ---------------------------------

   If the Company fails to attain or retain this Plan as a plan which qualifies 
under Code Section 401, then the Plan as adopted by the Company will no longer 
represent a prototype plan covered by an opinion letter issued by the Internal 
Revenue Service to the Sponsor as to the acceptability of the form of the Plan 
under Code Section 401(a). Rather, it will be considered an individually 
designed plan.

                                  APPENDIX A

                       Limitations on Elective Deferrals
                          and Matching Contributions


A.1 Definitions
- ---------------

These terms have the following meanings in this Appendix:

Actual Deferral Percentage: The ratio of Elective Deferrals (and Qualified 
Matching Contributions and Qualified Nonelective Contributions to the extent 
treated as Elective Deferrals under Section A.4) on behalf of the Eligible 
Participant for the Plan Year to the Eligible Participant's Compensation for the
Plan Year. In calculating the Actual Deferral Percentage, Elective Deferrals 
include Excess Deferral Amounts, but do not include Elective Deferrals that are 
taken into account in the Average Contribution Percentage Test (provided the 
Actual Deferral Percentage test is satisfied both with and without the exclusion
of these Elective Deferrals). The Actual Deferral Percentage of an Eligible 
Participant who does not make an Elective Deferral is zero. The amount of 
Compensation taken into account for an Employee who is an Eligible Participant 
at any time during the Plan Year, including the first Plan Year, equals the 
total Compensation received by the Employee for the Plan Year Plan Year 
(whether or not the Participant was an Eligible Participant for the entire Plan 
Year).

Aggregate Limit: The greater of (a) or (b), where:

(a)  is the sum of (i) 1.25 multiplied by the greater of the Average Actual
     Deferral Percentage or the Average Contribution Percentage for Eligible
     Participants who are Non-Highly Compensated Employees and (ii) the lesser
     of 200% or 2 plus the lesser of the Average Actual Deferral Percentage or
     the Average Contribution Percentage for Eligible Participants who are Non-
     Highly Compensated Employees; and

(b)  is the sum of (i) 1.25 multiplied by the lesser of the Average Actual
     Deferral Percentage or the Average Contribution Percentage for Eligible
     Participants who are Non-Highly Compensated Employees and (ii) the lesser
     of 200% or 2 plus the greater of the Average Actual Deferral Percentage or
     the Average Contribution Percentage for Eligible Participants who are Non-
     Highly Compensated Employees.

Average Actual Deferral Percentage: The average of the Actual Deferral 
Percentages of the Eligible Participants in a group.

Average Contribution Percentage: The average of the Contribution Percentages of 
the Eligible Participants in a group.

Contribution Percentage: The ratio of Matching Contributions (and Elective 
Deferrals and Qualified Nonelective Contributions to the extent treated as 
Matching Contributions under Section A.6) on behalf of the Eligible Participant 
for the Plan Year to the Eligible Participant's Compensation for the Plan Year.

Eligible Participant: To determine the Actual Deferral Percentage, any Employee 
who is eligible to have Elective Deferrals allocated to his Participant 401(k) 
Account for the Plan Year. To determine the Contribution Percentage, any 
Employee who is eligible to have Matching Contributions allocated to his 
Employer Contribution Account for the Plan Year.

Excess Aggregate Contributions: For any Plan Year, the excess of:

(a)  the aggregate amount of Matching Contributions (and participant
     contributions to another plan and, if applicable, Elective Deferrals and
     Qualified Nonelective Contributions) actually made on behalf of Highly
     Compensated Employees for the Plan Year, over

(b)  the maximum amount of those contributions permitted under the Average
     Contribution Percentage test in Section A.6 (determined by reducing
     contributions made on behalf of Highly Compensated Employees in the order
     of their Contribution Percentages beginning with the highest Contribution
     Percentage).

Excess Contributions: For any Plan Year, the excess of:

(a)  the aggregate amount of Elective Deferrals (and, if applicable, Qualified
     Matching Contributions and Qualified Nonelective Contributions) actually
     made on behalf of Highly Compensated Employees for the Plan Year, over

(b)  the maximum amount of those contributions permitted under the Actual
     Deferral Percentage test in Section A.4 (determined by reducing
     contributions made on behalf of Highly Compensated Employees in the order
     of their Actual Deferral Percentages beginning with the highest Actual
     Deferral Percentage).

Excess Deferral Amount: The amount of Elective Deferrals for a calendar year 
that are includible in a Par-

                                     -23-
<PAGE>
 
ticipant's gross income under Code Section 402(g) to the extent the 
Participant's Elective Deferrals exceed the dollar limitation under Code Section
402(g).

Matching Contribution: Under this Appendix, Matching Contribution also includes 
Employer contributions made to any other defined contribution plan on behalf of 
a Participant on account of a participant contribution made to any other plan of
an Employer or on account of the Participant's Elective Deferrals to this or any
other plan of an Employer.



A.2 Maximum Amount of Elective Deferrals
- ----------------------------------------

  No Employee may have Elective Deferrals under this Plan, or any other 
qualified plan of an Employer, during any taxable year in excess of the dollar 
limitation in Code Section 402(g) in effect at the beginning of that taxable 
year.



A.3 Excess Deferral Amounts
- ---------------------------

  A.3.1  Excess Deferral Amounts and income allocable to those amounts will be 
distributed no later than April 15 of each year to Participants who claim 
allocable Excess Deferral Amounts for the preceding calendar year.

  A.3.2  The Participant's claim must be written and submitted to the 
Administrative Committee no later than March 1. The claim must specify the 
Participant's Excess Deferral Amount for the preceding calendar year and must be
accompanied by the Participant's written statement that if those amounts are not
distributed, the Excess Deferral Amount, when added to amounts deferred under 
other plans or arrangements described in Code Section 401(k), 402(h)(1)(B), 
403(b), 457, 501(c)(18) exceeds the limit imposed on the Participant by Code 
Section 402(g) for the year in which the deferral occurred.

  A.3.3  The Excess Deferral Amount distributed to a Participant is adjusted for
income or loss. Income and loss allocable to Excess Deferral Amounts equals the 
sum of:

(a)  income or loss allocable to the Participant's Elective Deferrals for the
     taxable year multiplied by a fraction, the numerator of which is the
     Participant's Excess Deferral Amount for the taxable year, and the
     denominator is the Account Balance in his Participant 401(k) Account
     attributable to Elective Deferrals on the last day of that taxable year
     without regard to any income or loss occurring during that taxable year;
     plus

(b)  10% of the amount determined under (a) multiplied by the number of 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 the month.

  A.3.4  The Excess Deferral Amount distributed to a Participant is reduced by 
any Excess Contributions previously distributed to the Participant for the Plan
Year beginning with or within that taxable year. In no event may the amount 
distributed exceed the Participant's total Elective Deferrals for the taxable 
year.

  A.3.5  Excess Deferral Amounts are treated as Annual Additions under 
Appendix B.



A.4 Actual Deferral Percentage Test
- -----------------------------------

  A.4.1  The Average Actual Deferral Percentage for Eligible Participants who 
are Highly Compensated Employees for the Plan Year may not exceed:

(a)  the Average Actual Deferral Percentage for Eligible Participants who are 
     Non-Highly Compensated Employees for the Plan Year multiplied by 1.25; or

(b)  The Average Actual Deferral Percentage for Eligible Participants who are
     Non-Highly Compensated Employees for the Plan Year multiplied by 2,
     provided that the Average Actual Deferral Percentage for Eligible
     Participants who are Highly Compensated Employees does not exceed the
     Average Actual Deferral Percentage for Eligible Participants who are Non-
     Highly Compensated Employees by more than 2 percentage points or such
     lesser amount as the Secretary of the Treasury may prescribe to prevent the
     multiple use of this alternative limitation with respect to any Highly
     Compensated Employee.

  A.4.2  The provisions of Code Section 401(k)(3) and Department of Treasury 
Regulation 1.401(k)-1(b) are incorporated by reference.

  A.4.3  To the extent Elective Deferrals are taken into account under Section 
A.6, they are disregarded under this Section A.4.

  A.4.4  The Administrative Committee shall determine for any Plan Year whether 
Qualified Matching Con-

                                     -24-
<PAGE>
 
tributions and/or Qualified Nonelective Contributions will be treated as 
Elective Deferrals in the Actual Deferral Percentage test under this Section 
A.4. The Administrative Committee shall also determine whether the amounts 
treated as Elective Deferrals, subject to such other requirements as the 
Secretary of the Treasury may prescribe are:

(a)  all Qualified Matching Contributions;

(b)  all Qualified Nonelective Contributions;

(c)  such Qualified Matching Contributions as are needed to satisfy the Actual 
     Deferral Percentage test; or 

(d)  such Qualified Nonelective Contributions as are needed to satisfy the 
     Actual Deferral Percentage test.

   A.4.5 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 allocated to his account under 2 or more plans or 
arrangements described in Code Section 401(k) that are maintained by the Company
or an Affiliate is determined as if all Elective Deferrals (and, if applicable, 
Qualified Matching Contributions and Qualified Nonelective Contributions) were 
made under a single arrangement. If the cash or deferral arrangements have 
different plan years, all cash or deferred arrangements ending within the same 
calendar year are treated as a single arrangement. 

   A.4.6 If this Plan satisfies the requirements of Code Sections 401(a)(4),
401(k), or 410(b) only if aggregated with one or more other plans, or if one or
more other plans satisfy the requirements of those Code sections only if
aggregated with this Plan, then this Section A.4 is applied by determining the
Actual Deferral Percentage of Eligible Participants as if all the plans were a
single plan.

   A.4.7 The Administrative Committee also may treat one or more plans as a 
single plan with the Plan whether or not the aggregated plans satisfy Code 
Sections 401(a)(4) and 410(b). However, those plans must then be treated as one 
plan under Code Sections 401(a)(4), 401(k), and 410(b). Plans may be aggregated 
under this Section A.4.7 only if they have the same plan year.

   A.4.8 To determine the Actual Deferral Percentage of a Participant who is a 
5-percent owner or one of the 10 most highly-paid Highly Compensated Employees, 
the Elective Deferrals (and, if applicable, Qualified Matching Contributions and
Qualified Non-elective Contributions) and Compensation of the Participant 
includes the Elective Deferrals (and, if applicable, Qualified Matching 
Contributions and Qualified Nonelective Contributions) and Compensation of
Family Members. Family Members are disregarded as separate employees in
determining the Actual Deferral Percentage both for Participants who are Non-
Highly Compensated Employees and for Participants who are Highly Compensated
Employees.

   A.4.9 Elective Deferrals, Matching Contributions, and Nonelective 
Contributions are 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.

   A.4.10 The determination and treatment of the Elective Deferrals, Qualified 
Matching Contributions, Qualified Nonelective Contributions, and Actual Deferral
Percentage of any Participant must satisfy such other requirements as the 
Secretary of the Treasury may prescribe.



A.5 Excess Contributions
- ------------------------

  A.5.1. Excess Contributions and income allocable to those contributions will 
be distributed no later than the last day of each Plan Year to Participants to 
whose Account the Excess Contributions were made for the preceding Plan Year. 
Excess Contributions are allocated to Participants who are subject to the family
member aggregation rules of Code Section 414(q)(6) in the manner prescribed by 
regulations. The Administrative Committee anticipates that the Excess 
Contributions will be distributed to affected Participants within 2 1/2 months 
after the close of the Plan Year in which the Excess Contribution occurred. If 
Excess Contributions are not distributed to affected Participants within 2 1/2 
months after the close of the Plan Year, the Employer will be subject to a 10% 
excise tax under Code Section 4979.

  A.5.2 The Excess Contributions distributed to a Participant are adjusted for 
income and losses up to the date of distribution. The income or loss allocable 
to Excess Contributions equals the sum of:

(a) income or loss allocable to the Participant's Elective Deferrals (and, if 
    applicable, Qualified Matching Contributions and Qualified Nonelective
    Contributions treated as Elective Deferrals) for the Plan Year multiplied by
    a fraction, the numerator of which is the Participant's Excess Contributions
    for the Plan Year and the denominator is the Participant's Account Balances
    attributable to Elective Deferrals (and, if applicable, Qualified Matching
    Contributions and Qualified Nonelective Contributions) on the last day of
    the Pan Year without regard to any income or loss occurring during that Plan
    Year; plus

(b) 10% of the amount determined under (a) multiplied by the number of 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 the month.

                                     -25-
<PAGE>
 
  A.5.3  The Excess Contributions distributed to a Participant are also reduced 
by the amount of Excess Deferral Amounts distributed to the Participant.

  A.5.4  Amounts distributed under this Section A.5 are first treated as 
distributions from the Participant 401(k) Account and are treated as distributed
from the Participant's Employer Contribution Account only to the extent the 
Excess Contributions exceed the balance in his Participant 401(k) Account.

  A.5.5  Excess Contributions are treated as Annual Additions under Appendix B.



A.6 Average Contribution Percentage Test
- ----------------------------------------

  A.6.1  The Average Contribution Percentage for Eligible Participants who are 
Highly Compensated Employees for the Plan Year may not exceed:

(a)  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 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 2 percentage points or such lesser amount as the
     Secretary of the Treasury may prescribe to prevent the multiple use of this
     alternative limitation with respect to any Highly Compensated Employee.

  A.6.2  The provisions of Code Section 401(m) and any regulations issued 
thereunder are incorporated by reference.

  A.6.3  To the extent that Qualified Matching Contributions are taken into 
account under Section A.4, they are disregarded under this Section A.6.

  A.6.4  The Administrative Committee shall determine for any Plan Year whether 
Elective Deferrals and/or Qualified Nonelective Contributions will be treated as
Matching Contributions in the Average Contribution Percentage test under this 
Section A.6. The Administrative Committee shall also determine whether the 
amounts treated as Matching Contributions, subject to such other requirements as
the Secretary of the Treasury may prescribe, are:

(a)  all Elective Deferrals;

(b)  all Qualified Nonelective Contributions; 

(c)  such Elective Deferrals as are needed to satisfy the Average Contribution 
     Percentage test; or

(d)  such Qualified Nonelective Contributions as are needed to satisfy the 
     Average Contribution Percentage test.

  A.6.5  The Contribution Percentage for any Eligible Participant who is a 
Highly Compensated Employee for the Plan Year and who is eligible to receive 
Matching Contributions under 2 or more plans described in Code Section 401(a) 
or arrangements described in Code Section 401(k) that are maintained by the 
Company or an Affiliate is determined as if all Matching Contributions (and 
participant contributions to another plan) (and, if applicable, Elective 
Deferrals and Qualified Nonelective Contributions) were made under a single 
plan. If the plans have different plan years, all plans ending within the same 
calendar year are treated as a single plan.

  A.6.6  If this Plan satisfies the requirements of Code Sections 401(a)(4),
401(m) or 410(b) only if aggregated with one or more other plans, or if one or
more other plans satisfy the requirements of those Code sections only if
aggregated with this Plan, then this Section A.6 is applied by determining the
Contribution Percentages of Eligible Participants as if all the plans were a
single plan. In calculating Contribution Percentages under this paragraph,
participant contributions to the other plans are considered.

  A.6.7  The Administrative Committee may treat one or more plans as a single
plan with the Plan whether or not the aggregated plans satisfy Code Sections
401(a)(4) and 410(b). However, those plans must then be treated as one plan
under Code Sections 401(a)(4), 401(m), and 410(b). Plans may be aggregated under
this Section A.6.7 only if they have the same plan year.

  A.6.8  To determine the Contribution Percentage of an Eligible Participant who
is a 5-percent owner or one of the 10 most highly-paid Highly Compensated 
Employees, Matching Contributions (and participant contributions to another 
plan) (and, if applicable, Elective Deferrals and Qualified Nonelective 
Contributions) and Compensation of the Participant includes the Matching 
Contributions (and participant contributions to another plan) (and, if 
applicable, Elective Deferrals and Qualified Nonelective Contributions) and 
Compensation of Family Members. Family Members are disregarded as separate 
employees in determining the Contribution Percentage both for Eligible 
Participants who are Non-Highly Compensated Employees and for Eligible 
Participants who are Highly Compensated Employees.

  A.6.9  Matching Contributions and Qualified Nonelective Contributions are 
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.

                                     -26-

  A.6.10  The determination and treatment of the Contribution Percentage of any 
Participant must satisfy such other requirements as the Secretary of the
Treasury may prescribe.



A.7 Excess Aggregate Contributions
- ----------------------------------

  A.7.1  Excess Aggregate Contributions and income allocable to those 
contributions are forfeited, if otherwise forfeitable under this Plan, or if not
forfeitable, distributed no later than the last day of each Plan Year, to 
Participants to whose Accounts Matching Contributions were allocated for the 
preceding Plan Year. Excess Aggregate Contributions are allocated to 
Participants who are subject to the family member aggregation rules of Code 
Section 414(q)(6) in the manner prescribed by regulations. The Administrative 
Committee anticipates that the Excess Aggregate Contribution will be distributed
to affected Participants within 2 1/2 months after the close of the Plan Year in
which the Excess Aggregate Contribution occurred.

  A.7.2  If Excess Aggregate Contributions are not distributed to affected 
Participants within 2 1/2 months after the close of the Plan Year, the Employer 
will be subject to a 10% excise tax under Code Section 4979.

  A.7.3  The Excess Aggregate Contributions to be distributed are adjusted for 
income and losses up to the date of distribution. The income or loss allocable 
to Excess Aggregate Contributions equals the sum of:
 
(a)  income or loss allocable to the Participant's Matching Contributions (and,
     if applicable, Elective Deferrals and Qualified Nonelective Contributions
     treated as Matching Contributions) for the Plan Year multiplied by a
     fraction, the numerator of which is the Participant's Excess Aggregate
     Contributions for the Plan Year and the denominator is the Participant's
     Account Balances attributable to Matching Contributions (and, if
     applicable, Elective Deferrals and Qualified Nonelective Contributions) on
     the last day of the Plan Year without regard to any income or loss
     occurring during that Plan Year; plus

(b)  10% of the amount determined under (a) multiplied by the number of 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 the month.

  A.7.4  Amounts distributed under this Section A.7 are treated as distributions
from the Participant's Employer Contribution Account and, if applicable, on a 
pro rata basis from his Participant 401(k) Account.
- --------

  A.7.5  Amounts forfeited by Highly Compensated Employees under this Section 
A.7 are used to reduce Employer Contributions.

  A.7.6  Excess Aggregate Contributions are treated as Annual Additions under 
Appendix B.



A.8 Coordination of Distributions of Excess Deferral Amounts,
    Excess Contributions, and Excess Aggregate Contributions
- -------------------------------------------------------------

  Excess Deferral Amounts, Excess Contributions, and Excess Aggregate 
Contributions are calculated and distributed in that order.



A.9 Multiple Use of Alternative Limitation
- ------------------------------------------

  If the sum of the Average Actual Deferral Percentage and the Average 
Contribution Percentage for Eligible Participants who are Highly Compensated 
Employees exceeds the Aggregate Limit, a multiple use of the alternative 
limitation (within the meaning of Code Section 401(m)(9)) occurs. However, 
multiple use does not occur if either the Average Actual Deferral Percentage or
the Average Contribution Percentage for Eligible Participants who are Highly 
Compensated Employees does not exceed 1.25 multiplied by the Average Actual 
Deferral Percentage or the Average Contribution Percentage, as applicable, for 
Eligible Participants who are Non-Highly Compensated Employees. Under this 
Section A.9, the Average Actual Deferral Percentage and the Average Contribution
Percentage for Eligible Participants who are Highly Compensated Employees are 
determined after any corrections required to meet the Actual Deferral Percentage
test and the Average Contribution Percentage test. Multiple use is corrected by 
reducing the Actual Deferral Percentage of all Highly Compensated Employees so 
that the Aggregate Limit is not exceeded. The amount of the reduction is treated
as an Excess Contribution.

                                  APPENDIX B

                        Limitations on Annual Additions

 
B.1 Definitions
- ---------------

These terms have the following meanings in this Appendix:

Annual Addition: The sum of the following amounts credited to a Participant's 
Accounts for any Limitation Year:

(a)  contributions made by any Controlled Group Member;

(b)  participant contributions to any other qualified plan of a Controlled Group
     Member even if withdrawn during the same Limitation Year;

(c)  forfeitures allocated to any defined contribution plan maintained by a 
     Controlled Group Member;

(d)  amounts attributable to post-retirement medical benefits, allocated to the
     separate account of a key employee as defined in Code Section 419A(d)(3),
     under all welfare benefit funds as defined in Code Section 419(e)
     maintained by any Controlled Group Member; and

(e)  amounts allocated to an individual medical account as defined in Code
     Section 415(l)(l) which is part of a pension or annuity plan maintained by
     any Controlled Group Member.

Any Excess Amount applied under Section B.3.1 and B.3.3 in the Limitation Year 
to reduce Controlled Group Member contributions will be considered Annual 
Additions for that Limitation Year.

Controlled Group Member: Any corporation during the time it is a member of a
"controlled group of corporations" (as defined in Code Section 414(b) as
modified by Code Section 415(h)) of which the Company is a member and any trade
or business during the time it is under "common control" (as defined in Code
Section 414(c) as modified by Code Section 414(h)) with the Company, or any
affiliated service group as defined in Code Section 414(m), or any other entity
required to be aggregated with the Employee under Code Section 414(o).

Defined Benefit Fraction: For any Participant, the fraction (determined as of
the last day of the Limitation Year) with a numerator equal to the Projected
Annual Benefit of the Participant and a denominator equal to the lesser of:

(a)  1.25 multiplied by the dollar limitation in effect under Code Section 
     415(b)(l)(A) and (d) for that Limitation Year; or 

(b)  1.4 multiplied by the amount of the Participant's average Limitation
     Compensation for the consecutive 3 Years of Service that produces the
     highest average.

If the Participant was a participant as of the first day of the Limitation Year 
beginning after December 31, 1986, in one or more defined benefit plans 
maintained by a Controlled Group Member which were in existence on May 6, 1986, 
the denominator of this fraction will not be less than 125 percent of the sum of
the annual benefits under those 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 requirements of Code Section 415 for
all Limitation Years beginning before January 1, 1987.

Defined Contribution Dollar Limitation: $30,000 or, if greater, 1/4 of the 
dollar limitation in effect under Code Section 415(b)(l)(A) as in effect for the
Limitation Year.

Defined Contribution Fraction: For any Participant, the fraction (determined as 
of the last day of the Limitation Year) with a numerator equal to the sum of all
the Participant's Annual Additions and a denominator equal to the sum of the 
lesser of the following amounts determined for the Limitation Year and for each 
prior Limitation Year for which the Participant was credited with a Year of 
Service:

(a)  1.25 multiplied by the Defined Contribution Dollar Limitation in effect for
     that Limitation Year; or

(b)  1.4 multiplied by 25% of the Participant's Limitation Compensation for that
     Limitation Year.

  If the Participant was a participant as of the first day of the Limitation
Year beginning after December 31, 1986, in one or more defined benefit plans
maintained by a Controlled Group Member 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, disregarding 
any changes in the terms and conditions of the Plan after May 5, 1986, but using
the Code Section 415 limitation applicable to the first Limitation Year 
beginning on or after January 1, 1987.

                                     -28-
<PAGE>
 
  The Annual Addition for any Limitation Year beginning before January 1, 1987, 
is not recomputed to treat all employee contributions as Annual Additions.

Excess Amount: The excess of the Participant's Annual Additions for the 
Limitation Year over the maximum Annual Addition permitted under Section B.2.

Limitation 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 Controlled Group Member 
maintaining the Plan (including, but not limited to, commissions paid to 
salesmen, compensation for services on the basis of a percentage of profits, 
commissions on insurance premiums, tips, and bonuses), and excluding the 
following:

(a)  Controlled Group Member contributions to a plan of deferred compensation
     which are not includible in the Participant's gross income for the taxable
     year in which contributed, or Controlled Group Member contributions under a
     simplified employee pension plan to the extent those contributions are
     deductible by the Participant, or any distributions from a plan of deferred
     compensation;

(b)  Amounts realized from the exercise of a non-qualified stock option, or when
     restricted stock (or property) held by the Participant 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

(d)  other amounts which received special tax benefits, or contributions made by
     the Controlled Group Member (whether or not under a salary reduction
     agreement) toward the purchase of an annuity described in Code Section
     403(b) (whether or not the amounts are actually excludible from the gross
     income of the Participant).

  Limitation Compensation for a Limitation Year is the compensation actually 
paid or includible in gross income during that Limitation Year. However, for a 
Non-Highly Compensated Employee who is permanently and totally disabled within 
the meaning of Code Section 22(e)(3) and for whom contributions are 
nonforfeitable when made, "Limitation Compensation" means the limitation 
compensation the Participant would have received if the Participant was paid at 
the same rate as immediately before becoming permanently and totally disabled.

Limitation Year: The Plan Year. All qualified plans maintained by a Controlled 
Group Member 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.

Master or Prototype Plan: A plan the form of which is the subject of a 
favorable opinion letter from the Internal Revenue Service.

Projected Annual Benefit: The Participant's annual benefit payable in the form 
of a straight life annuity or a qualified joint and survivor annuity under all 
defined benefit plans qualified under Code Section 401 maintained at any time 
(whether or not terminated) by the Company or any other Controlled Group Member.
The Projected Annual Benefit is computed assuming that the Participant will 
remain employed until normal retirement age under the Plan (or his current age, 
if later) and that the Participant's Compensation (and all other relevant 
factors used to determine benefits) will remain at its current level until that 
time.


B.2 Maximum Annual Addition
- ---------------------------

  B.2.1  A Participant's Annual Addition in any Limitation Year may not exceed 
the lesser of:

(a)  the Defined Contribution Dollar Limitation; or

(b)  25% of the Participant's Limitation Compensation (other than any
     contribution for medical benefits within the meaning of Code Sections
     401(h) or 419A(f)(2) which is treated as an Annual Addition) for that
     Limitation Year;

  If a short Limitation Year is created by an amendment changing the Limitation 
Year to a different 12-month period, the maximum Annual Addition may not exceed 
the Defined Contribution Dollar Limitation multiplied by the following fraction;
number of months in the short Limitation Year over 12.

  B.2.2  Before determining the Participant's actual Limitation Compensation for
the Limitation Year, the Employer may determine the maximum Annual Addition 
under Section B.2.1 for a Participant on the basis of a reasonable estimation of
the Participant's Limitation Compensation for the Limitation Year, uniformly 
determined for all Participants similarly situated.

  B.2.3  As soon as administratively feasible after the end of the Limitation 
Year, the maximum Annual Addition under Section B.2.1 will be determined on the 
basis of the Participant's actual Limitation Compensation for the Limitation 
Year.

                                     -29-
<PAGE>
 
B.3 Excess Amounts
- ------------------

  B.3.1 If the Participant does not participate in, and has never participated 
in another qualified plan maintained by a Controlled Group Member, a welfare 
benefit fund as defined in Code Section 419(e) maintained by a Controlled Group 
Member, or an individual medical account as defined in Code Section 415(1)(2) 
maintained by a Controlled Group Member, which provides an Annual Addition, the 
Employer contribution to this Plan that would otherwise be contributed or 
allocated to the Participant's Account will be limited to ensure that there will
be no Excess Amount for the Limitation Year. If the Employer contribution that 
would otherwise be contributed or allocated to the Participant's Account would 
cause the Annual Addition for the Limitation Year to exceed the maximum Annual 
Addition, the amount contributed or allocated will be reduced so that the Annual
Additions for the Limitation Year will equal the maximum Annual Addition. 
However, if pursuant to Section B.2.3, there is an Excess Amount, the excess 
will be disposed of as follows:

(a)  If 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 that
     Participant in the next Limitation Year, and each succeeding Limitation
     Year if necessary;

(b)  If the Participant is not covered by the Plan at the end of the Limitation
     Year, the Excess Amount is held unallocated in a suspense account and will
     be used to reduce future Employer contributions for all remaining
     Participants in the next Limitation Year and each succeeding Limitation
     Year, if necessary.

(c)  A suspense account may not participate in the allocation of the gains and
     losses of the Investment Funds. All amounts in the suspense account must be
     allocated and reallocated to Participants' Accounts before any Employer
     contributions may be made for that Limitation Year. Excess Amounts in a
     suspense account may not be distributed to Participants or former
     Participants.

  B.3.2  This Section B.3.2 and Sections B.3.3 and B.3.4 apply if, in addition 
to this Plan, the Participant is covered under another qualified defined 
contribution Master or Prototype Plan maintained by a Controlled Group Member, a
welfare benefit fund, as defined in Code Section 419(e), maintained by a 
Controlled Group Member, or an individual medical account, as defined in Code 
Section 415(1)(2), maintained by a Controlled Group Member, which provides an 
Annual Addition during any Limitation Year. The Annual Additions which may be 
credited to a Participant's account under this Plan for any such Limitation Year
when added to the Annual Additions credited to a Participant's account under the
other plans and welfare benefit funds for the same Limitation Year may not 
exceed the maximum Annual Addition under Section B.2.1. If the Annual Additions 
with respect to the Participant under other defined contribution plans and 
welfare benefit funds maintained by a Controlled Group Member are less than the 
maximum Annual Addition under Section B.2.1 and the Controlled Group Member 
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 Annual Addition under Section B.2.1. 
If the Annual Additions with respect to the Participant under the other defined 
contribution plans and welfare benefit funds in the aggregate are equal to or 
greater than the maximum Annual Addition, no amount will be contributed or 
allocated to the Participant's Account under this Plan for the Limitation Year.

  B.3.3  If, pursuant to Section B.2.3 or as a result of the allocation of 
forfeitures, a Participant's Annual Additions under this Plan and the 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.

  B.3.4  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 that date, times

(b)  the ratio of (i) the Annual Additions allocated to the Participant for the
     Limitation Year as of that date under this Plan to (ii) the total Annual
     Additions allocated to the Participant for the Limitation Year as of that
     date under this and all the other Master or Prototype Plans. Any Excess
     Amount attributed to this Plan will be disposed in the manner described in
     Section B.3.1.

  B.3.5  This Section B.3.5 applies if the Participant is covered under another 
qualified defined contribution plan maintained by a Controlled Group Member 
which is not a Master or 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 B.3.2 through B.3.4 as though the other plan
were a Master or Prototype Plan unless the Company provides other limitations in
Section I.A of the Addendum to the Adoption Agreement.

  B.3.6  This Section B.3.6 applies in addition to the limitations of Section 
B.2.1 if a Participant has participated in any defined benefit plan maintained 
at any time (whether or not terminated) by the Company or any other

                                     -30-
<PAGE>
 
Controlled Group Member. The sum of the Participant's Defined Benefit Fraction 
and the Participant's Defined Contribution Fraction may not exceed 1.0. If 
necessary, the Annual Addition which may be credited under this Plan for any 
Limitation Year will be reduced in accordance with Section I.B of the Addendum 
to the Adoption Agreement.

  B.3.7  If this Plan is a restatement of a plan which satisfied Code Section 
415 for all Limitation Years beginning before January 1, 1987, then, in 
accordance with regulations promulgated by the Secretary of the Treasury, an 
amount (not exceeding the numerator of the Defined Contribution Plan Fraction)
is subtracted from that numerator so that the sum of the Defined Benefit Plan 
Fraction and the Defined Contribution Plan Fraction under Code Section 415(e)(1)
does not exceed 1.0 for the year. The adjustment described in the preceding
sentence is determined as if the Tax Reform Act of 1986 changes to the
limitation on contributions and benefits were in effect for the last year
beginning before January 1, 1987.

  B.3.8  The amount of Employer contributions which may not be allocated to the 
Participant 401(k) Account of a particular Participant because of the 
limitations of this Section B.2 will be considered to have been made by mistake 
of fact and will be returned to the Employer.

  B.3.9  The limitations of this Appendix B are intended to comply with Code 
Section 415 so that the maximum contributions and benefits provided by the 
Company and Controlled Group Members will exactly equal the maximum amounts 
allowed under Code Section 415. Any discrepancy between this Section and Code 
Section 415 will be resolved so as to give full effect to Code Section 415.

                                  APPENDIX C

                             Top-Heavy Provisions


C.1 Definitions
- ---------------

These terms have the following meanings in this Appendix:

Aggregated Plans: (a) All plans of the Company or an Affiliate which must be 
aggregated with the Plan, and (b) all plans of the Company or an Affiliate which
may be aggregated with the Plan and which the Administrative Committee elects to
aggregate with the Plan, in determining whether the Plan is top-heavy. A plan
must be aggregated with the Plan if the plan includes as a participant a Key
Employee or if the plan enables any plan of the Company or Affiliate in which a
Key Employee participates to qualify under Code Section 401(a)(4) or Section
410. A plan of the Company or an Affiliate may be aggregated with the Plan if
the plan satisfies the requirements of Code Sections 401(a)(4) and 410, when
considered together with this Plan and all plans which must be aggregated with
this Plan. No plan may be aggregated with this Plan unless it is a qualified
plan under Code Section 401. The top-heavy status of Aggregated Plans is
determined by aggregating the plans' respective top-heavy determinations that
are made as of the Determination Dates that fall within the same calendar year.

Determination Date: The date as of which it is determined whether a plan is 
top-heavy or super top-heavy for the Plan Year immediately after the 
Determination Date. The Determination Date for any Plan Year is the last day of 
the preceding Plan Year, or for the first Plan Year, the last day of that year.

Group Participant: Anyone who is or was a participant in any Aggregated Plan as 
of the Determination Date or any of the 4 immediately preceding Determination 
Dates. Any Beneficiary of a Group Participant who has received, or is expected
to receive, a benefit from an Aggregated Plan is considered a Group Participant
solely for determining whether the Plan is top-heavy or super top-heavy.

Key Employee: Any Employee or former Employee, or their Beneficiaries, of the 
Company or an Affiliate who, as of a Determination Date, or as of any of the 4 
immediately preceding Determination Dates, was:
(a)  an officer of the Company earning in excess of 50% of the amount in effect 
     under Code Section 415(b)(l)(A); or
(b)  a 5-percent owner of the Company; or
(c)  a 1-percent owner of the Company whose total annual compensation from the 
     Company and the Affiliates exceeds $150,000; or
(d)  an Employee whose compensation equals or exceeds $30,000 (or such higher
     amount as may be defined under Code Section 415(c)(l)(A)), and whose
     ownership interest (determined in accordance with Code Section 51) in the
     Company and the Affiliates is among the 10 largest.
   Under this Appendix, "compensation" means compensation as defined in Code 
Section 415(c)(3), but including Employer contributions made pursuant to a 
salary reduction agreement which are not includible in the individual's gross 
income under Code Section 125, 402(a)(8), 402(b), or 403(b).
   The determination of who is a Key Employee is made in accordance with Code 
Section 416(i)(l).

Non-Key Employee: Any Employee who is not a Key Employee including an Employee 
who is a former Key Employee.

Top-Heavy Ratio:

(a)  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 Aggregated Plans 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 Code Section 416
     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 Code Section 416 and the regulations thereunder.

(b)  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 plans which during the 5-year period ending
     on the Determination Date(s) has or has had any accrued benefits, the Top-
     Heavy

                                     -32-
<PAGE>
 
     Ratio for the Aggregated Plans 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 (a) 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 (a) 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 Code Section
     416 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.

(c)  For purposes of (a) and (b) 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 Code Section 416 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 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 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 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 Code Section 
411(b)(1)(C).



C.2 Top-Heavy Plan
- ------------------

  C.2.1  The rules in this Appendix apply to a Plan for the first Plan Year 
beginning after the Determination Date as of which the Plan is top-heavy or 
super top-heavy. Except where expressly indicated otherwise, those rules 
continue to apply until, as of a later Determination Date, the Plan is no longer
top-heavy or super top-heavy. However, if the Plan changes from being super 
top-heavy to being top-heavy, the rules for a top-heavy plan will apply and if 
the Plan changes from being top-heavy to being super top-heavy, the rules for a 
super top-heavy plan will apply.

  C.2.2  For any Plan Year, the Plan is "top-heavy" if the Top-Heavy Ratio 
exceeds 60% determined as of the Determination Date immediately before that Plan
Year.

  C.2.3  For any Plan Year, the Plan is "super top-heavy" if the Top-Heavy Ratio
exceeds 90% determined as of the Determination Date immediately before that 
Plan-Year.

  C.2.4  The Value of Accumulated Benefits for Key Employees under all 
Aggregated Plans and the Value of Accumulated Benefits for all Group 
Participants under all Aggregated Plans are increased to reflect any 
contributions not actually made as of the Determination Date, but which must be 
taken into account on that date under Code Section 416.



C.3 Minimum Benefits or Contributions
- -------------------------------------

  C.3.1  For any Plan Year in which the Plan is top-heavy, the minimum rate of 
contributions and forfeitures allocated to the account of any Participant 
employed by the Company on the last day of the Plan Year is determined without 
regard to any Social Security contribution and regardless of whether the 
Participant has completed 1,000 Hours of Service (or any equivalent provided in 
the Plan) or whether the Participant has compensation less than a stated amount.
The minimum contribution is equal to the lesser of:

(a)  the highest rate of employer contributions and forfeitures (determined as a
     percentage of Compensation) allocated to the account of any Key Employee;
     and

(b)  3% (4% if the Plan is super top-heavy) of Compensation.

                                     -33-
<PAGE>
 
  C.3.2  If a Participant also participates in another defined contribution plan
of the Company or an Affiliate, the minimum allocation described above will be 
provided under the other plan or this Plan as elected in Section VI.A of the 
Adoption Agreement. If the Participant also participates in one or more defined 
benefit plans of the Company or an Affiliate, the minimum required benefits or 
allocations under Code Section 416 will be provided under either this Plan or 
the defined benefit plan as elected in Section VI.B of the Adoption Agreement.

  C.3.3  Neither Elective Deferrals nor Matching Contributions made on behalf of
Non-Key Employees may be used to satisfy the minimum contribution requirement of
this Section C.3.



C.4 Adjustment to Maximum Benefits
- ----------------------------------

  For any Plan Year in which the Plan is top-heavy, the maximum benefit which 
may be provided under Appendix B is determined by substituting "1.00" for "1.25"
wherever it appears in that Appendix. However, if the Plan is not super top-
heavy for that Plan Year, then the preceding sentence does not apply if "4%" is 
substituted for 3% in Section C.3.1(b).



C.5 Discontinuance of Appendix
- ------------------------------

  If any provision of this Appendix is no longer required to qualify the Plan 
under the Code, then that provision will become void without the necessity of 
further Plan amendment.

                                     -34-

                                  APPENDIX D

                           Distribution Requirements


D.1 Definitions
- ---------------

These terms have the following meanings in this Appendix:

Applicable Life Expectancy:

(a)  The life expectancy (or joint and last survivor expectancy) calculated
     using the attained age of the Participant as of the Participant'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.

(b)  Life expectancy and joint and last survivor expectancy are computed by use
     of the expected return multiples in Table V and VI of section 1.72-9 of the
     income tax regulations.

Distribution Calendar Year: A calendar year for which a minimum distribution is
required. The first Distribution Calendar Year is the calendar year immediately
preceding the calendar year which contains the Participant's Required Beginning 
Date.

Participant's Benefit:

(a)  The Account Balances 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 contributions 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)  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 is treated as if it had been made in the immediately preceding
     Distribution Calendar Year.

Required Beginning Date: The first day of April of the calendar year following 
the calendar year in which the Participant attains age 70 1/2.




D.2 General Rules
- -----------------

  D.2.1  The requirements of this Appendix apply to any distribution of the
Participant's interest and take precedence over any inconsistent provisions of
this Plan.

  D.2.2  All distributions required under this Plan are determined and made in 
accordance with the proposed regulations under Code Section 401(a)(9), including
the minimum distribution incidental benefit requirement of Section 1.401(a)(9)-2
of the proposed regulations.

  D.2.3  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 lesser of (a)
the Applicable Life Expectancy or (b) if the Participant's spouse is not the 
designated beneficiary, the applicable divisor determined from the table set 
forth in Q&A 4 of proposed Treasury Regulation Section 1.401(a)(9)-1.

  D.2.4  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 
Participant's Required Beginning Date occurs, must be made on or before December
31 of that Distribution Calendar Year.

  D.2.5  If an amount is transferred or rolled over from another plan to this 
Plan the rules in Q&A J-2 and Q&A J-3 of proposed Treasury Regulation Section 
1.401(a)(9)-1 apply.

                                   AGREEMENT
                                   ---------


     THIS AGREEMENT is made and entered into as of _____________, 1997, by and
between NETVANTAGE, INC., a Delaware corporation (the "Company"), and STEPHEN R.
RIZZONE ("Employee").

                                    RECITALS
                                    --------

     A.  The Company and Employee were parties to an Employment Agreement
effective as of March 26, 1996 (the "1996 Employment Agreement"), under which
Employee was entitled to receive certain nonstatutory stock options (the "1996
Employment Agreement Performance Options"), among others, if certain specified
performance criteria were achieved by the Company.

     B.  In late 1996, the Board of Directors of the Company adopted an
executive bonus plan under which Employee was entitled to receive a nonstatutory
stock option (the "Bonus Plan Performance Option"), if certain specified
performance criteria were achieved by the Company.

     C.  The Company and Employee are parties to an Employment Agreement
effective as of January 1, 1997 (the "1997 Employment Agreement") (the 1996
Employment Agreement and the 1997 Employment Agreement sometimes being
collectively referred to as the "Employment Agreements"), under which Employee
is entitled to receive certain additional nonstatutory stock options (the "1997
Employment Agreement Performance Options") (the 1996 Employment Agreement
Performance Options, the Bonus Plan Performance Option and the 1997 Employment
Agreement Performance Options sometimes being collectively referred to as the
"Performance Options" and individually referred to as a "Performance Option"),
among others, if certain specified performance criteria are achieved by the
Company.

     D.  Three Nonstatutory Stock Option Agreements, each dated as of March 26,
1996, covering up to 50,000 shares, 50,000 shares and 10,000 shares,
respectively, of Class A Common Stock of the Company, were prepared to evidence
the 1996 Employment Agreement Performance Options; a Nonstatutory Stock Option
Agreement, dated as of September 19, 1996, covering 35,000 shares of Class A
Common Stock of the Company, was prepared to evidence the Bonus Plan Performance
Option; and agreements were not prepared to evidence the 1997 Employment
Agreement Performance Options.

     E.  Exhibit A to this Agreement is a complete list of all other options to
purchase shares of capital stock of the Company held by Employee (the "Other
Options").

     F.  The Company and Employee at the time the Performance Options were
granted were mistaken in their belief that the performance criteria would be
beneficial to the Company and without adverse consequence; but recently they
discovered the potential unintended consequence that such Performance Options
would result in compensation expense to the Company for financial accounting
purposes.
<PAGE>
 
     G.  The Company and Employee wish by this Agreement to rescind each of the
Performance Options and amend the Employment Agreements.

     ACCORDINGLY, in consideration of the forgoing and for good and valuable

accepted by the parties, the parties agree as follows:

Option, with the effect that each Performance Option shall be treated as if it

         ------------------------------------------                          
and 9f of the 1997 Employment Agreement are hereby deleted in their entirety,

     strike price of the 1996 ESOP options will be the average of the bid/ask

     outstanding performance and contributions to the company.  These grants are
