Livingston's high performance, integrated remote access solutions enable ISPs
worldwide to cost-effectively connect their subscribers to the Internet. All of
the Company's remote access products incorporate Livingston's ComOS operating
system, which has been architected specifically for remote access applications
to provide robust routing, security, centralized device management and
subscriber administration functions. The Company believes that more ISPs
worldwide use Livingston's remote access servers than those of any other vendor.
Since the Company's introduction of its first remote access server in 1990, over
2,000 ISPs have purchased the Company's products.

Housed within the ISP's local Point of Presence, Livingston's remote access
products connect dial-up subscribers communicating with the ISP over standard
analog, ISDN, Frame Relay or T1/E1 leased line connections to the Internet via
the ISP's router-based network. The Company's ComOS operating system enables the
ISP to perform a number of critical functions including:
 
- - Routing: support for TCP/IP, IPX, OSPF, PPP, RIP and other LAN/WAN protocols

The PortMaster 3 combines the Company's core software technology, the ComOS
operating system, with a streamlined hardware design to offer ISPs the following
advantages:
 
- - Integrated hardware solution
 
- - Designed to support emerging technologies such as 56K modems

                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND FINANCIAL STATEMENTS AND NOTES THERETO APPEARING ELSEWHERE IN
THIS PROSPECTUS.
 
                                  THE COMPANY
 
    Livingston is a leading provider of integrated remote access networking
solutions for ISPs worldwide. Used by ISPs to connect their subscribers to the
Internet, the Company's remote access servers deliver high performance at a low
price per port, making them particularly well-suited for the intensely
competitive ISP market. The Company also provides office routers and firewall
routers that are resold by ISPs to corporate customers for Internet connectivity
and other remote access networking applications. The Company believes that more
ISPs worldwide use Livingston's remote access servers than those of any other
vendor. Since the Company's introduction of its first remote access server in
1990, over 2,000 ISPs have purchased the Company's remote access products.
 
    In November 1996, the Company introduced the PortMaster 3 access
concentrator, its next generation remote access platform, which integrates
digital modem, router and communications server functionality with support for
analog modems, ISDN PRI, Frame Relay and T1/E1 service connections in a compact
3.5 inch high chassis. The PortMaster 3 has been designed to be easily upgraded
to support emerging technologies such as 56K modem functionality. The PortMaster
3 combines the Company's core software technology, the ComOS operating system,
with an integrated hardware design that provides ISPs with a high port density,
highly scalable remote access solution. Architected specifically for remote
access applications, ComOS is incorporated in all of the Company's remote access
products and provides robust routing, security, centralized device management
and subscriber administration capabilities. The Company believes that the
PortMaster 3 platform positions it to better address the needs of large ISPs and
Telcos, and to maintain its leadership position with the Company's established
base of local and regional ISP customers.

                                  THE COMPANY
 
    Livingston Enterprises, Inc. ("Livingston" or the "Company") is a leading
provider of integrated remote access networking solutions for Internet Service
Providers ("ISPs") worldwide. Used by ISPs to connect their subscribers to the
Internet, the Company's remote access servers deliver high performance at a low
price per port, making them particularly well-suited for the intensely
competitive ISP market. The Company also provides office routers and firewall
routers that are resold by ISPs to corporate customers for Internet connectivity
and other remote access networking applications. The Company believes that more
ISPs worldwide use Livingston's remote access servers than those of any other
vendor. Since the Company's introduction of its first remote access server in
1990, over 2,000 ISPs have purchased the Company's remote access products.
 
    In November 1996, the Company introduced the PortMaster 3 access
concentrator, its next generation remote access platform, which integrates
digital modem, router and communications server functionality with support for
analog modems, ISDN PRI, Frame Relay and T1/E1 service connections in a compact
3.5 inch high chassis. The PortMaster 3 has been designed to be easily upgraded
to support emerging technologies such as 56K modem functionality. The PortMaster
3 combines the Company's core software technology, the ComOS operating system,
with an integrated hardware design that provides ISPs with a high port density,
highly scalable remote access solution. Architected specifically for remote
access applications, ComOS is incorporated in all of the Company's remote access
products and provides robust routing, security, centralized device management
and subscriber administration capabilities. The Company believes that the
PortMaster 3 platform positions it to better address the needs of large ISPs and
Telcos, and to maintain its leadership position with the Company's established
base of local and regional ISP customers.
 
    The number of Internet subscribers and Internet traffic is growing rapidly
as the Internet continues to emerge as a global medium for communication,
commerce and entertainment. To accommodate Internet subscriber growth and
customers' increasing bandwidth requirements, many ISPs are dramatically
increasing their investments in networking infrastructure, particularly in the
area of remote access equipment.
 
    The ISP market is evolving rapidly and competition in the industry has
intensified as many major telecommunications service providers have entered or
announced plans to enter the ISP market. ISPs increasingly need to provide
reliable service with maximum accessibility and minimum downtime to maintain
customer satisfaction, forcing ISPs to continually expand and upgrade their
networks without service interruption. Competition to attract and maintain
subscribers requires ISPs to improve the performance of their networks by
incorporating new technologies such as 56K modems. As a result, ISPs are
increasingly focused on procuring remote access equipment that is
cost-effective, reliable, scalable and interoperable, includes comprehensive
network management and security capabilities and provides support for emerging
technologies.
 
    Livingston's goal is to be the leading supplier of technologically advanced
and cost-effective remote access solutions to ISPs worldwide. Livingston's
strategy is to leverage its flexible ComOS operating system and its modular
hardware design to provide cost-effective, highly scalable and reliable remote
access technologies that incorporate next generation networking functionality.
The Company is focused on maintaining its market leadership with local and
regional ISPs, continuing to build its direct sales and technical support
capabilities, and increasing its market share with major national and
international ISPs. The Company also plans to expand its presence in Europe,
Japan and other international markets.

                                  RISK FACTORS
 
    IN ADDITION TO THE OTHER INFORMATION IN THIS PROSPECTUS, THE FOLLOWING
FACTORS SHOULD BE CONSIDERED CAREFULLY IN EVALUATING AN INVESTMENT IN THE SHARES
OF COMMON STOCK OFFERED HEREBY. THIS PROSPECTUS CONTAINS FORWARD-LOOKING
STATEMENTS WHICH INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS
COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD-LOOKING
STATEMENTS AS A RESULT OF CERTAIN FACTORS, INCLUDING THOSE SET FORTH BELOW AND
ELSEWHERE IN THIS PROSPECTUS.
 
    UNPREDICTABLE AND FLUCTUATING QUARTERLY OPERATING RESULTS.  Due to the
emerging and evolving nature of the markets for the Company's products and the
likelihood of increased competition, there can be no assurance that growth in
net revenues will continue or that the Company will continue to be profitable.
As a result of the Company's recent transition to its new product, PortMaster 3,
the Company believes that future quarterly operating results could be negatively
impacted by factors such as a continuing decline in sales of many of the
Company's earlier generation products, which the Company expects, and a lack of
sustained market acceptance of PortMaster 3. In addition, the Company expects
that software licensing royalties from US Robotics Access Corp., Inc. ("USR")
will terminate in fiscal 1998, if not sooner. For the Company's fiscal year
ended August 31, 1996 and the six months ended February 28, 1997, royalty
revenues from USR represented 6.2% and 12.9% of net revenues, respectively. To
the extent that such termination in royalty revenue and a decline in revenue of
the Company's earlier generation products is not offset by sales of PortMaster 3
and future products, the Company's business, quarterly operating results and
financial condition would be materially adversely affected. The Company's
quarterly operating results could also be materially adversely affected by a
wide variety of factors including the following: price competition; the mix of
products sold; the ability of the Company to provide product features required
by ISPs; product flaws that cannot be detected or remedied in a timely manner;
shortages of critical components; the buying patterns of ISPs and other
customers; the level of Internet usage by customers of ISPs; the ability of the
Company to succeed in selling products to large ISPs, interexchange carriers
such as AT&T, MCI and Sprint, and Regional Bell Operating Companies ("RBOCs")
(interexchange carriers and RBOCs may be collectively referred to as "Telcos");
the ability of the Company to hire and retain additional sales personnel;
consolidation in the ISP markets; the mix of distribution channels employed by
the Company; changes in the levels of inventory held by third party resellers;
the timing of orders from, and shipments to, customers; and seasonality and
general economic conditions. The Company typically operates with a relatively
small backlog and, as a result, quarterly sales 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 spending is relatively fixed in advance based 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 quarterly operating results
may be magnified by the Company's inability to adjust spending to compensate for
the shortfall. As a result of the Company's plans to expand its direct sales and
marketing and research and development capabilities, the Company anticipates
that its operating expenses will substantially increase, which, in the absence
of increased sales of the Company's products, could have a material adverse
effect on the Company's quarterly operating results. Accordingly, there can be
no assurance that the Company will be able to sustain profitability in the
future, particularly on a quarter-to-quarter basis, or that the Company will not
experience material fluctuations in quarterly operating results. Additionally,
it is possible that the Company's future quarterly operating results may fall
below the expectations of analysts and investors. In such event, the market
price of the Company's Common Stock would likely be materially adversely
affected. See "--Possible Volatility of Stock Price" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

    DEPENDENCE ON SALES OF PORTMASTER 3.  In the fall of 1996, the Company
introduced PortMaster 3, sales of which represented a majority of the Company's
net revenues in the second quarter of fiscal 1997. There can be no assurance
that such level of sales will be maintained. In particular, there can be no
assurance that the initial level of sales does not reflect pent up demand from
prior quarters as a result of the anticipated introduction of PortMaster 3. In
addition, future sales of PortMaster 3 would be materially adversely affected in
the event that the Company is unable to offer on a timely basis a 56K modem
upgrade for PortMaster 3. Sales of PortMaster 3 would also be materially
adversely affected in the event that the ISP market widely adopts an alternative
56K modem technology such as USR's x2 modem technology. See "--Risks Associated
with 56K Modem Technology." From time to time, the Company's products may
contain product flaws. Due to the complexity of the PortMaster 3, there can be
no assurance that the PortMaster 3 does not contain undetected product flaws or
that the Company will be able to timely or effectively remedy such flaws. See
"--Risks Associated with Rapid Technological Changes." In addition, because the
PortMaster 3 is the Company's first product intended to address large ISPs and
Telcos, there can be no assurance that this product will prove suitable for, or
achieve acceptance in, these markets. See "--Risks Associated with Entry into
New and Unfamiliar Markets." Sales of the Company's earlier generation
PortMaster products declined in the fourth quarter of fiscal 1996 and the six
months ended February 28, 1997, and the Company expects such sales will continue
to decline and that the Company will be increasingly dependent upon sales of
PortMaster 3 to sustain and grow its net revenues. There can be no assurance
that sales of PortMaster 3 will be sufficient to sustain and grow the Company's
net revenues. The inability of the Company to increase sales of its PortMaster 3
would have a material adverse effect on the Company's business, results of
operations and financial condition. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business--Industry
Background and Market" and "--Technology and Products."
 
    RISKS ASSOCIATED WITH NEW PRODUCT INTRODUCTIONS.  The market for the
Company's products is characterized by rapidly changing technologies, evolving
industry standards, frequent competitive product introductions and short product
life cycles. The Company's introduction of new or enhanced products requires the
Company to effectively manage the transition from older products to newer
generation products in order to minimize disruption in customer ordering
patterns, avoid excessive levels of older product inventories and ensure that
adequate supplies of new products can be delivered to meet customer demand. In
the past, the Company has experienced problems with product transitions. For
example, the Company experienced a decrease in net revenues in the fourth
quarter of fiscal 1996, when sales of the Company's earlier generation products
decreased primarily as a result of the anticipated introduction of PortMaster 3.
As a result, the Company recorded charges aggregating approximately $3.3 million
through the first quarter of fiscal 1997 as a reserve for obsolete PortMaster 2
inventory. A failure by the Company to effectively manage new product
introductions in the future could have a material adverse effect on the
Company's business, results of operations and financial condition. See "--Risks
Associated with Rapid Technological Changes."
 
    DEPENDENCE ON SALES TO LOCAL AND REGIONAL ISPS.  Historically, the Company
has sold a substantial majority of its products to local and regional ISPs. The
business of local and regional ISPs is largely dependent upon free reciprocal
access to networks of large regional and national ISPs. Recently, certain
national ISPs have announced that they plan to eliminate such free access to
local and regional ISPs. There can be no assurance such limitations, or other
limitations by national ISPs, would not materially adversely impact the growth
or success of local and regional ISPs and thereby materially adversely impact
the sales of the Company's products. Additionally, local and regional ISPs often
have limited access to capital and as a result may be constrained in their
ability to purchase the Company's products. Accordingly, there can be no
assurance that sales to such ISPs, individually or as a group, will equal or
exceed historical levels in any future period. A decrease in purchases of the
Company's products by local and regional ISPs generally would materially
adversely affect the Company's business, results of operations and financial
condition.

See "Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Sales and Marketing."
 
    RISKS ASSOCIATED WITH 56K MODEM TECHNOLOGY.  Modem technology is rapidly
evolving and with the recent introduction of 56K modem technology, ISPs are
increasingly demanding remote access solutions that incorporate 56K modem
technology. There currently are two principal competing 56K modem technologies:
(i) the x2 modem technology developed by USR and (ii) the K56flex modem
technology developed by Lucent Technologies ("Lucent") and Rockwell
Semiconductor Systems, Inc. ("Rockwell"). The Company has adopted the
Lucent/Rockwell technology and has announced its offer to provide an upgrade,
when and if available, to existing PortMaster 3 customers, upon request and at
no additional charge, to support K56flex specifications. The Company does not
plan to support the USR technology. In the event that USR's technology becomes
widely adopted by ISPs, or an industry standard is adopted that is not
compatible with the 56K modem solution implemented by the Company, the Company's
business, results of operations and financial condition would be materially
adversely affected. The Company believes that in order to remain competitive it
must successfully introduce a 56K modem solution before the end of fiscal 1997.
The Company depends on Lucent for the development of microchips for its 56K
implementation. There can be no assurance that Lucent will be able to deliver to
the Company sufficient quantities of 56K microchips, that the Company will not
experience problems or delays incorporating these microchips into its products
or that the Company will not experience other difficulties introducing a 56K
modem solution. The inability of the Company to offer a 56K modem solution on a
timely basis would materially adversely impact sales of the PortMaster 3 and
would have a material adverse effect on the Company's business, results of
operations and financial condition. See "--Dependence on Sales of PortMaster 3."
 
    RISKS ASSOCIATED WITH ENTRY INTO NEW AND UNFAMILIAR MARKETS.  To date, a
substantial majority of the Company's revenues have been derived from sales to
local and regional ISPs. With the introduction of PortMaster 3, the Company
believes that it can better address the needs of large ISP and Telco markets.
These markets are characterized by longer, more costly sales cycles and
substantially greater competition than the local and regional ISP markets. Many
of the Company's competitors, such as Ascend Communications, Inc. ("Ascend"),
USR and Cisco Systems, Inc. ("Cisco"), have substantially greater resources,
name recognition and experience than the Company, as well as established
relationships with many of the large ISPs and Telcos. Because the PortMaster 3
is the Company's first product intended to address large ISPs and Telcos, there
can be no assurance that this product will prove suitable for, or achieve
acceptance in, these markets. To enter into and compete in these markets, the
Company will be required to expand its sales and marketing capabilities, which
will result in increased operating expenses. See "--Intense Competition,"
"--Dependence on Developing a Direct Sales Capability" and "--Unpredictable and
Fluctuating Quarterly Operating Results." To the extent that the Company is
unable to penetrate such markets for its products or sales of products in these
unfamiliar markets do not offset such increased expenses, the Company's
business, results of operations and financial condition could be materially
adversely affected.
 
    INTENSE COMPETITION.  The remote access market is intensely competitive and
the Company's principal competitors include Ascend, USR and Cisco. Competitive
factors in the remote access ISP market include the breadth of product features,
pricing, product quality, reliability and functionality, marketing and sales
resources, customer service and support and reputation. Competition in the large
ISP and Telco segments of the remote access market is particularly intense and
the Company's competitors have greater name recognition, resources, sales
capabilities and market share than the Company. As a result, the Company has a
competitive disadvantage in these markets. Increased competition could result in
price reductions, the inability of the Company to increase market share, or a
loss of market share by the Company, any of which could materially adversely
affect the Company's business, results of operations and financial condition.
Additionally, industry-wide consolidation, such as the recently announced
mergers of USR with 3Com Systems, Inc. ("3Com") and Ascend with Cascade
Communications, Inc. ("Cascade"), could result
 
                                       7
<PAGE>
in increased competition in the remote access ISP market because, among other
things, such companies will be able to provide a complete solution for
integrated remote access combined with other networking products not offered by
the Company. Furthermore, the ISP industry could experience consolidation and
the acquisition of one of the Company's larger customers by a corporation with
relationships with one of the Company's competitors could result in a loss of
revenue attributable to such customer. To the extent Telcos increase their share
of the ISP market and the Company is unsuccessful in penetrating the Telco
segment of the market, the Company's business, results of operations and
financial condition could be materially adversely affected. There can be no
assurance that the Company's current and future competitors will not develop or
market technologies and products that offer higher performance and are more
cost-effective than the Company's current or future products, thereby rendering
the Company's technologies and products obsolete. See "Business--Competition."
 
    DEPENDENCE ON DEVELOPING A DIRECT SALES CAPABILITY.  The Company believes
that it must augment its direct sales capability in order to effectively compete
in the large ISP and Telco markets. Accordingly, the Company has expanded, and
plans to continue to expand, its direct sales capabilities to establish direct
customer relationships. However, there can be no assurance that the Company will
be able to find, train and retain sufficient personnel to enhance or further
develop such direct sales capability or that the Company will be successful in
penetrating the large ISP and Telco markets. The market in which the Company
competes is characterized by intense competition for attracting and retaining
qualified sales personnel and there can be no assurance that the Company will be
successful in competing for such personnel. Many of the Company's competitors
have significant direct sales departments and possess substantially greater
resources to attract such personnel. In the event that the Company is
unsuccessful in developing its direct sales capability, the Company's business,
results of operations and financial condition could be materially adversely
affected.
 
    RISKS ASSOCIATED WITH RELIANCE ON RESELLERS.  For the year ended August 31,
1996 and for the six months ended February 28, 1997, 88.1% and 82.9%,
respectively, of the Company's product revenues were made through value added
resellers and distributors ("resellers"). The Company's top ten resellers
represented 73.8% and 59.3%, respectively, of product revenues during such
periods. The Company's top reseller in each period represented 27.2% and 17.4%,
respectively, of the Company's product revenues and the second largest reseller
in each period represented 13.3% and 10.3%, respectively. Accordingly, the
Company is dependent upon the continued viability and financial stability of its
resellers. Furthermore, the Company expects to become more dependent upon
resellers in the international markets. While the Company maintains contractual
relationships with most of its resellers, these agreements generally do not
require a reseller to purchase the Company's products and may be terminated by a
reseller at any time without penalty. There can be no assurance that any of the
Company's resellers will continue to market the Company's products.
Additionally, the Company's resellers generally offer products of several
different companies, including those of the Company's competitors. Consequently,
there is a risk that resellers will give higher priority to products of other
suppliers, thus reducing their efforts to sell the Company's products. The
foregoing risk is exacerbated by the Company's plans to expand its direct sales
capability which could have a negative impact on the Company's relationship with
resellers and result in a reduction in the sales of the Company's products by
such resellers. In addition, the Company may, from time to time, terminate some
of its relationships with resellers and any such termination could have a
material adverse effect on the Company's business and result in threatened or
actual litigation. For example, in November 1996, the Company terminated its
relationship with one of its largest resellers, who then threatened to sue the
Company. There can be no assurance that any future termination of a reseller
would not have a material adverse effect on the Company's business or that such
termination would not result in a lawsuit or that the Company would be
successful in defending itself in such a lawsuit. Livingston provides most of
its resellers with product return rights for stock balancing and price
protection. There can be no assurance that the Company will not experience
significant product returns or claims for price protection with respect to
products held by resellers which could materially adversely affect the Company's
business, results of
 
                                       8

operations and financial condition. See "--Risks Associated with International
Sales" and "Business-- Sales and Marketing."
 
    RISKS ASSOCIATED WITH THE MANAGEMENT OF EXPANDING OPERATIONS.  The Company
has recently experienced a period of rapid growth and an expansion in the number
of its employees, the scope and complexity of its operating and financial
systems, and the geographic area of its operations. Such growth has placed and,
if sustained, will continue to place a significant strain upon the Company's
management, operations, financial systems and resources. The Company believes
that it must expand its manufacturing, research and development, marketing,
sales and customer support capabilities in order to effectively serve the
evolving needs of the Company's present and future customers. The Company's
Chief Executive Officer also serves as the Company's Chief Technical Officer and
the Company's Vice President of Sales also serves as the Company's Vice
President of Marketing. Consequently, the Company believes it needs to hire
additional senior management in the areas of research and development and
marketing. There can be no assurance that this can be achieved without
disruption to the Company's current management team. The failure by the Company
to hire additional qualified personnel in a timely manner could have a material
adverse effect on the Company's business, results of operations and financial
condition. See "--Dependence on Key Personnel" and "Management."
 
    RISKS ASSOCIATED WITH RAPID TECHNOLOGICAL CHANGES.  The market for the
Company's products is characterized by rapidly changing technologies, evolving
industry standards, frequent competitive product introductions and short product
life cycles. The Company's success will depend to a substantial degree upon its
ability to enhance its existing products and to develop and introduce, on a
timely and cost-effective basis, new products and features that meet changing
customer requirements and emerging industry standards. Inherent in the product
development process are a number of risks. The development of new,
technologically advanced products is a complex and uncertain process requiring
high levels of innovation, as well as the accurate anticipation of technological
and market trends. The Company's introduction of new or enhanced products may
contain undetected or unresolved software or hardware defects when they are
first introduced or as new versions are released. There can be no assurance
that, despite extensive testing by the Company, design defects will not be found
in new products or upgrades after commencement of commercial shipments,
resulting in additional costs to the Company, reduced acceptance of the
Company's products or damage to the Company's reputation and relationships with
its customers. Future delays in the introduction or shipment of new or enhanced
products, the inability of such products to gain market acceptance or problems
associated with new product transitions could have a material adverse effect on
the Company's business, results of operations and financial condition,
particularly on a quarterly basis. See "--Unpredictable and Fluctuating
Quarterly Operating Results," "--Risks Associated with New Product
Introductions," "Management's Discussion and Analysis of Financial Condition and
Results of Operations" and "Business--Industry Background and Market" and
"--Research and Development."
 
    RISKS ASSOCIATED WITH INTERNATIONAL SALES.  International sales accounted
for approximately 29.7% and 44.7% of the Company's product revenues in fiscal
1996 and the six months ended February 28, 1997, respectively, and the Company
expects that international sales will continue to account for a significant
portion of its product revenues in future periods. The Company is substantially
dependent on resellers for its international sales. Certain of the Company's
resellers also act as resellers for the Company's competitors and such resellers
could devote greater effort and resources to marketing competitive products. The
loss of certain resellers could have a material adverse effect on the Company's
business, results of operations and financial condition. In addition, in each
calendar year sales in Europe and certain other parts of the world in the third
quarter and sales in Japan in the second quarter are typically adversely
affected as many customers reduce their business activities during those
periods. The Company intends to enter into additional international markets and
to continue to expand its operations outside of North America by expanding its
direct sales force, adding resellers and pursuing additional strategic
relationships
 
                                       9
<PAGE>
which will require significant management attention and expenditure of
significant financial resources. Sales to international customers are subject to
additional risks including longer receivables collection periods, greater
difficulty in accounts receivable collection, political and economic
instability, nationalization, trade restrictions, the impact of possible
recessionary environments in economies outside the United States, reduced
protection for intellectual property rights in some countries, currency
fluctuations and tariff regulations and requirements for export licenses. In
particular, United States law currently prohibits the export of certain
encryption technology which the Company may include in its future products. To
the extent the export or import of the Company's products is prohibited by the
domestic laws of the United States or any foreign country in which the Company
does business, or uncertainty relating to such laws limits the marketability of
the Company's products internationally, the Company could lose a substantial
portion of its international sales. There can be no assurance that the foregoing
risks associated with international sales will not materially adversely impact
the future level of such sales and, consequently, the Company's business,
results of operations and financial condition.
 
    Although the Company's international sales are currently denominated in U.S.
dollars, fluctuations in currency exchange rates could cause the Company's
products to become relatively more expensive to customers in a particular
country, leading to a reduction in sales or profitability in that country.
Furthermore, future international activity may result in foreign currency
denominated sales, and, in such event, gains and losses on the conversion to
U.S. dollars of accounts receivable and accounts payable arising from
international operations may contribute to fluctuations in the Company's results
of operations. These factors may have a material adverse effect on the Company's
business, results of operations and financial condition. See "--Risks Associated
with Reliance on Resellers," "--Tariff and Regulatory Matters," "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business--Sales and Marketing."
 
    DEPENDENCE ON KEY PERSONNEL.  The Company's success depends on the
continuing contributions of its key personnel, all of whom would be difficult to
replace. In particular, the Company is dependent upon Steven M. Willens, who
serves as the Company's Chief Technical Officer as well as its President and
Chief Executive Officer. The Company has no long-term employment arrangements
with Mr. Willens. While the Company has a key man life insurance policy in the
amount of $5 million on the life of Mr. Willens with the Company designated as
beneficiary, the loss of Mr. Willens' services would have a material adverse
effect upon the Company. The Company's future success will depend, in part, upon
its ability to attract and retain highly qualified personnel. There can be no
assurance that the Company will be successful in hiring or retaining qualified
personnel. Loss of, or the inability to hire, key personnel could have a
material adverse effect on the Company's business, results of operations and
financial condition. See "--Risks Associated with the Management of Expanding
Operations" and "Management."
 
    DEPENDENCE ON CONTRACT MANUFACTURERS AND SINGLE-SOURCE SUPPLIERS.  The
Company's production operations consist primarily of materials planning and
procurement, quality control, kitting and final assembly, burn-in and testing of
certain products. The Company designs all of the hardware subassemblies for its
products and uses the services of contract manufacturers to build these
subassemblies and certain of its products to the Company's specifications. The
Company is also dependent upon single or limited source suppliers for a number
of components and parts used in the Company's products, including certain key
microprocessors and integrated circuits. There can be no assurance that these
independent contractors and suppliers will be able to meet the Company's future
requirements for manufactured products, components and subassemblies. The
Company generally purchases single or limited source components pursuant to
purchase orders and has no guaranteed supply arrangements with these suppliers.
For example, the Company currently purchases all of its modem microchips from
Analog Devices, Inc. and with the Company's implementation of 56K modem
technology, the Company anticipates that it will become dependent upon Lucent
for modem microchips. In addition, the availability of many of these components
is dependent in part on the Company's ability to provide its suppliers with
accurate forecasts of its future
 
                                       10
<PAGE>
requirements. 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 replacement
component into the Company's products could disrupt its operations and have a
material adverse effect on the Company's business, results of operations and
financial condition in any given period. The Company purchases certain
components from foreign suppliers and the supply of such components could be
materially adversely affected by changing tariff and regulatory structures,
particularly those affecting the import and export of electronics and
technology. The Company may also be subject to increases in component costs,
which could also have a material adverse effect on the Company's business,
results of operations and financial condition. See "Business--Manufacturing."
 
    RISKS ASSOCIATED WITH LEGAL PROCEEDINGS.  The Company recently settled a
lawsuit with USR (the "Settlement") arising from a dispute regarding an OEM
Software License and Development Agreement between the parties dated September
1, 1994 (the "USR Agreement"). USR currently uses code developed by USR based on
Livingston's ComOS operating system in USR's NETServer access server card, which
is incorporated into its Total Control Enterprises Network Hub. In addition, the
USR NetServer 8 and 16 products use code also based on Livingston's ComOS. The
Company believes that its royalty revenue from the USR Agreement will terminate
in fiscal 1998, if not sooner. USR has substantially greater resources than the
Company and no assurance can be given that the Company will be able to
successfully compete with USR or that the Company and USR will not enter into
future litigation concerning the relationship between the two corporations and
their respective technologies. See "-- Dependence on Proprietary Technology."
The occurrence of future litigation with USR could have a material adverse
effect on the Company's business, results of operations and financial condition.
 
    In April 1997, a complaint for unfair competition was filed against the
Company as one of a group of companies separately developing 56K modem
technology by a plaintiff on behalf of the general public. The complaint alleges
that the Company knowingly made false and misleading statements regarding the
capabilities of its 56K modem technology. The Company believes that this case is
without merit and intends to vigorously defend its position. Nevertheless,
litigation is subject to inherent uncertainties and thus there can be no
assurance that this suit will be resolved favorably to the Company or that it
will not have a material adverse effect on the Company's business, results of
operations and financial condition.
 
    DEPENDENCE ON PROPRIETARY TECHNOLOGY.  The Company's future success and
ability to compete is dependent in part upon its proprietary technology. The
Company relies on a combination of contractual rights, trade secrets and
copyright laws to establish and protect its proprietary technology. The Company
currently has one patent application pending, but there can be no assurance that
a patent will be issued as a result of such application, that the Company's
patent will be upheld as valid, or that such patent will prevent the development
of competitive products. The Company generally enters into confidentiality
agreements with its employees, consultants, resellers, customers and potential
customers, and strictly limits access to and distribution of its source code,
and further limits the disclosure and use of other proprietary information.
However, as a result of the Company's licensing relationship with USR, the
Company has licensed, for a specified term, to USR the source code to its ComOS
operating software and in the event that such source code is released to
unauthorized third parties before the expiration of the license, the Company
could be materially adversely affected. There can be no assurance that the steps
taken by the Company in this regard will be adequate to prevent misappropriation
of its technology or that the Company's competitors will not independently
develop technologies that are substantially equivalent or superior to the
Company's technology. In addition, the laws of some foreign countries do not
protect the Company's proprietary rights to the same extent as do the laws of
the United States. See "--Risks Associated with Legal Proceedings."
 
    The Company is also subject to the risk of adverse claims and litigation
alleging infringement of the intellectual property rights of others. There can
be no assurance that third parties will not assert
 
                                       11
<PAGE>
infringement claims in the future with respect to the Company's current or
future products or that any such claims will not require the Company to enter
into license arrangements or develop non-infringing technology, or result in
litigation, regardless of the merits of such claims. In addition, any such
litigation could result in product delays or costs which could have a material
adverse effect on the Company's business, results of operations and financial
condition. No assurance can be given that any necessary licenses will be
available or that, if available, such licenses can be obtained on commercially
reasonable terms. The failure of the Company to adequately obtain such licenses,
or to protect its own proprietary technology through contractual rights, trade
secrets, patent and copyrights laws, could have a material adverse effect on the
Company's business, results of operations and financial condition. See
"Business-- Proprietary Rights."
 
    TARIFF AND REGULATORY MATTERS.  Rates for telecommunications services are
governed by tariffs of licensed carriers that are subject to regulatory
approval. Future changes in these tariffs could have a material adverse effect
on the Company's business, results of operations and financial condition. For
example, should tariffs for public switched digital services increase in the
future relative to tariffs for private leased services, the cost-effectiveness
of the Company's products would be reduced, and its business, results of
operations and financial condition could be materially adversely affected. In
addition, the Company's products must meet standards and receive certification
for connection to the public telecommunications network prior to their sale. In
the United States, the Company's products must comply with Part 15(a)
(industrial equipment), Part 15(b) (residential equipment) and Part 68 (analog
lines) of the Federal Communications Commission regulations. The Company's
products also must be certified by domestic telecommunications carriers in both
the United States and in foreign countries. In foreign countries, the Company's
products are subject to a wide variety of government review and certification
requirements. The Company is currently undertaking an effort to qualify for ISO
9002 series quality certification in order to fulfill the quality system
requirements for the European markets. Foreign customers typically require that
the Company's products receive certification from the country's primary
telecommunication carriers. The failure to obtain on a timely basis or retain
domestic certification or foreign regulatory approvals could have a material
adverse effect on the Company's business, results of operations and financial
condition. See "Business--Industry Background and Market."
 
    CONTROL BY OFFICERS AND DIRECTORS; CERTAIN FAMILY RELATIONSHIPS.  Following
this offering, the Company's executive officers and directors, together with
entities affiliated with such individuals, will beneficially own approximately
   % of the Company's Common Stock (approximately    % if the Underwriters'
over-allotment option is exercised in full). Following this offering, Steven
Willens, the Company's President, Chief Executive Officer and Chairman of the
Board, Ronald Willens, the Company's Executive Vice President, Secretary, a
director and the father of Steven Willens, and Jerrold Livingston, a director,
former President and Chief Executive Officer and the father-in-law of Steven
Willens will beneficially own approximately    % of the Company's outstanding
Common Stock. Accordingly, these shareholders will be able to elect at least a
majority of the Company's directors, will retain the voting power to approve all
matters requiring shareholder approval and will continue to have significant
influence over the affairs of the Company. This concentration of ownership could
have the effect of delaying or preventing a change in control of the Company.
See "Management" and "Principal and Selling Shareholders."
 
    BROAD DISCRETION OF MANAGEMENT TO ALLOCATE OFFERING PROCEEDS.  The Company
will use the proceeds from this offering for general corporate purposes,
including working capital and as a result, the Company's management will have
broad discretion to allocate the proceeds of this offering and to determine the
timing of expenditures. See "Use of Proceeds."
 
    ABSENCE OF DIVIDENDS.  The Company has not paid any dividends on its Common
Stock since its inception and does not anticipate paying any dividends upon its
Common Stock in the foreseeable future.
 
                                       12
<PAGE>
    NO PRIOR PUBLIC TRADING MARKET.  Prior to this offering, there has been no
public market for the Common Stock, and there can be no assurance that an active
trading market will develop or be sustained. The initial public offering price,
which will be established by negotiations between the Company and the
Underwriters, may not be indicative of the market price of the shares of Common
Stock after the offering. See "Underwriters."
 
    POSSIBLE VOLATILITY OF STOCK PRICE.  The equity markets, particularly the
market for high-technology corporations, recently have experienced significant
price and volume fluctuations that are unrelated to the operating performance of
individual companies. These broad market fluctuations may materially adversely
affect the market price of the Common Stock. In addition, the market price of
the shares of Common Stock is likely to be highly volatile. Factors such as
fluctuations in the Company's operating results, announcements of technological
innovations or new products by the Company or its competitors, developments with
respect to patents or proprietary rights, announcement of litigation by or
against the Company, changes in stock market analyst recommendations regarding
the Company or its competitors and general market conditions may have a material
adverse effect on the market price of the Common Stock.
 
    CERTAIN ANTI-TAKEOVER PROVISIONS.  Certain provisions of the Company's
Articles of Incorporation and Bylaws, each as amended, may have the effect of
making it more difficult for a third party to acquire, or of discouraging a
third party from attempting to acquire, control of the Company. Such provisions
could limit the price that certain investors might be willing to pay in the
future for shares of the Company's Common Stock. Certain of these provisions
provide for a classified board of directors and eliminate cumulative voting in
the election of directors. In addition, upon completion of this offering, the
Company's Board of Directors will have the authority to issue up to 5,000,000
shares of Preferred Stock and to determine the price, rights, preferences,
privileges and restrictions, including voting rights, of those shares without
any further vote or action by the shareholders. The rights of the holders of
Common Stock will be subject to, and may be materially adversely affected by,
the rights of the holders of any Preferred Stock that may be issued in the
future. The issuance of Preferred Stock, while providing flexibility in
connection with possible financings or acquisitions or other corporate purposes,
could have the effect of making it more difficult for a third party to acquire a
majority of the outstanding voting stock of the Company. The Company has no
current plans to issue shares of Preferred Stock. The Company's Bylaws and
indemnity agreements provide that the Company will indemnify officers and
directors against losses they may incur in legal proceedings resulting from
their service to the Company. These provisions may make it more difficult for
shareholders to take certain corporate actions and could have the effect of
delaying or preventing a change in control of the Company.
 
    SHARES ELIGIBLE FOR FUTURE SALE.  Sales of Common Stock (including shares
issued upon the exercise of outstanding options) in the public market after this
offering could materially adversely affect the market price of the Common Stock.
Such sales also might make it more difficult for the Company to sell equity
securities or equity-related securities in the future at a time and price that
the Company deems appropriate. Upon completion of this offering (based on shares
outstanding at April 30, 1997), the Company will have outstanding an aggregate
of         shares of Common Stock, assuming no exercise of the Underwriters'
over-allotment option and no exercise of outstanding options. Of these shares,
all of the shares sold in this offering will be freely tradeable without
restriction or further registration under the Securities Act, unless such shares
are purchased by "affiliates" of the Company as that term is defined in Rule 144
under the Securities Act (the "Affiliates"). The remaining 12,370,272 shares of
Common Stock held by existing shareholders are "restricted securities" as that
term is defined in Rule 144 under the Securities Act ("Restricted Shares").
Restricted Shares may be sold in the public market only if registered or if they
qualify for an exemption from registration under Rules 144 or 701 promulgated
under the Securities Act. As a result of the contractual restrictions described
below and the provisions of Rules 144 and 701, the Restricted Shares will be
available for sale in the public market as follows: (i) no shares will be
eligible for immediate sale on the date of this Prospectus; (ii) 33,000 shares
will be eligible for sale
 
                                       13
<PAGE>
beginning 90 days after the date of this Prospectus; and (iii) 12,337,272 shares
will be eligible for sale upon expiration of the lock-up agreements 180 days
after the date of this Prospectus. All officers, directors, shareholders and
certain option holders of the Company have agreed not to offer, pledge, sell,
contract to sell, grant any option, right or warrant to purchase, or otherwise
transfer or dispose of, directly or indirectly (or enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of), any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for shares of Common Stock, for
a period of 180 days after the date of this Prospectus, without the prior
written consent of Morgan Stanley & Co. Incorporated. The Company intends to
file a registration statement on Form S-8 which would allow shares issuable upon
exercise of options previously granted to be freely tradeable following release
of such lock-up obligations, subject to compliance with Rule 144 in the case of
Affiliates of the Company. See "Shares Eligible for Future Sale."
 
    IMMEDIATE AND SUBSTANTIAL DILUTION.  Purchasers of the Common Stock offered
hereby will suffer an immediate and substantial dilution of $     per share in
the net tangible book value of the Common Stock from the initial public offering
price of $     per share. To the extent outstanding options to purchase the
Company's Common Stock are exercised, there will be further dilution. See
"Dilution."

<PAGE>
                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the         shares of
Common Stock offered by the Company hereby are estimated to be approximately
$     million (approximately $     million if the Underwriters' over-allotment
option is exercised in full), at an assumed initial public offering price of
$     per share and after deducting estimated underwriting discounts and
commissions and estimated offering expenses payable by the Company. The
principal purposes of this offering are to obtain additional equity capital, to
create a public market for the Common Stock and to facilitate future access by
the Company to the capital markets. The Company expects to use the net proceeds
of this offering for general corporate purposes, including working capital. The
Company expects to use approximately $2.5 million of the net proceeds for
capital expenditures over the next twelve months. A portion of the net proceeds
may also be used for the acquisition of businesses, products and technologies
that are complementary to those of the Company. The Company has no present
plans, agreements or commitments with respect to any such transaction. Pending
such uses, the Company intends to invest the net proceeds of this offering in
short-term, interest-bearing, investment-grade securities.
 
                                DIVIDEND POLICY
 
    The Company has never declared or paid cash dividends on its Common Stock
and does not anticipate paying cash dividends in the foreseeable future. In
addition, the Company's bank line of credit prohibits the payment of cash
dividends without the bank's consent.

    The following table sets forth the consolidated capitalization of the
Company as of February 28, 1997 (i) on an actual basis and (ii) as adjusted to
give effect to the receipt by the Company of the estimated net proceeds from the
sale of         shares of Common Stock offered by the Company hereby at an
assumed initial public offering price of $     per share and after deducting
estimated underwriting discounts and commissions and estimated offering expenses
payable by the Company.

                                    DILUTION
 
    The net tangible book value of the Company as of February 28, 1997, was
$19,966,000 or $1.61 per share of Common Stock. Net tangible book value per
share is determined by dividing the tangible book value of the Company (total
tangible assets less total liabilities) by the number of outstanding shares of
Common Stock at that date. After giving effect to the sale by the Company of the
        shares of Common Stock offered hereby at an assumed initial public
offering price of $     per share, and after deducting underwriting discounts
and commissions and estimated offering expenses payable by the Company, the
Company's as adjusted net tangible book value at February 28, 1997 would have
been $        or $     per share. This represents an immediate increase in net
tangible book value of $     per share to existing shareholders and an immediate
dilution of $     per share to new public investors. The following table
illustrates the per share dilution:

    The foregoing analysis assumes no exercise of the Underwriters'
over-allotment option and no exercise of stock options outstanding at February
28, 1997. As of February 28, 1997, there were options outstanding to purchase a
total of 2,444,275 shares of Common Stock at a weighted average exercise price
of $3.17 per share. In addition, in May 1997, the Board of Directors adopted the
1997 Stock Plan and the 1997 Employee Stock Purchase Plan, pursuant to which
1,500,000 and 500,000 shares, respectively, were reserved for issuance
thereunder. As of May 12, 1997, no options or shares had been issued under any
of these plans. Subsequent to February 28, 1997, the Board of Directors granted
options under the 1994 Stock Plan to purchase an additional 246,250 shares of
Common Stock at a weighted average exercise price of $14.23 per share. To the
extent these stock options are exercised, there will be further dilution to
purchasers in this offering. See "Management--Executive Compensation,"
"Description of Capital Stock" and Note 5 of Notes to Consolidated Financial
Statements.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
    Livingston is a leading provider of remote access networking solutions for
ISPs worldwide. In 1990, the Company introduced its first PortMaster
communications server incorporating its proprietary ComOS operating system,
which was developed specifically for remote access applications. In 1991, the
Company introduced its remote access routers which are resold by ISPs to
corporate customers for Internet connectivity and other remote access networking
applications. In November 1996, the Company began shipping its PortMaster 3
access concentrator which incorporates the Company's enhanced ComOS, support for
high speed digital connections such as ISDN PRI and T1/E1, and up to 60 digital
modems. Because this remote access solution includes modem functionality, the
PortMaster 3 has a substantially higher selling price than the Company's earlier
generation products. The PortMaster 3 has been designed to be easily upgraded to
support emerging technologies such as 56K modem functionality. The Company has
announced its offer to provide this upgrade, when and if available, to existing
PortMaster 3 customers, upon request, at no additional charge. The Company
accrues for the cost of providing the 56K upgrade at the time of sale. Sales of
the PortMaster 3 have increased significantly since its introduction while sales
of the Company's earlier generation communications servers have declined. The
Company believes that it will be dependent upon sales of the PortMaster 3 for a
majority of the Company's net revenues for the foreseeable future. See "Risk
Factors--Dependence on Sales of PortMaster 3."
 
    In 1994, the Company entered into an OEM Software License and Development
agreement with USR, pursuant to which the Company receives software license
royalties related to sales by USR of products that incorporate the Company's
ComOS operating system. Royalty payments are normally received by Livingston
sixty days after USR's quarter end, and are recorded as royalty revenue at that
time. Through February 28, 1997, cumulative royalties from USR totaled $7.2
million. As a result of the Settlement with USR, the Company expects royalty
revenues from USR to terminate in fiscal 1998, if not earlier. See "Risk
Factors--Risks Associated with Legal Proceedings."
 
    International sales accounted for 29.7% and 44.7% of the Company's product
revenues in fiscal 1996 and the first six months of fiscal 1997, respectively.
The Company expects that international sales will continue to account for a
significant portion of its product revenues in future periods. Although the
Company's international sales are currently denominated in U.S. dollars,
fluctuations in currency exchange rates could cause the Company's products to
become relatively more expensive to customers in a particular country, leading
to a reduction in sales or profitability in such country. Furthermore, future
international activity may result in foreign currency denominated sales, and, in
such event, gains and losses on the conversion to U.S. dollars of accounts
receivable and accounts payable arising from international operations may cause
material fluctuations in the Company's results of operations.
 
    Historically, the majority of the Company's sales have been made to local
and regional ISPs through the Company's reseller channel. In connection with the
introduction of the PortMaster 3, the Company began to significantly expand its
direct sales force in order to better address the needs of large ISPs and
Telcos. Recently, the Company has expanded its direct sales force and has
established eight branch offices in North America, European headquarters in
France and a branch office in the United Kingdom. In response to growth in the
ISP market and the Company's expanded base of customers, the Company has
significantly increased its research and development activities. The Company has
also expanded its technical support operations and manufacturing capacity. These
activities, and the expansion of the Company's infrastructure to support them,
have resulted in significantly higher operating expenses in fiscal 1996 and the
first two quarters of fiscal 1997.
 
    The Company typically provides certain postcontract customer support ("PCS")
in connection with the sale of its products. Prior to the second quarter of
fiscal 1996, PCS consisted principally of telephone
 
                                       19
<PAGE>
support and minor maintenance for its PortMaster 2 products. During this period,
the Company recognized revenue at the time of product shipment and accrued the
estimated costs of providing PCS. During the second quarter of fiscal 1996, the
Company decided to provide significant feature enhancements to ComOS, free of
charge, to the Company's installed customer base. Accordingly, the Company
recognized the portion of product revenue attributable to the value of PCS
ratably over 12 months, the period during which PCS is expected to be provided.
In November 1996, the Company began selling PortMaster 3, which is accompanied
by a one year hardware and software warranty. The portion of the PortMaster 3
selling price that is attributable to PCS is recognized ratably over the 12
month support period. Additional warranty and support coverage is made available
to PortMaster 3 customers as a purchase option. PCS revenues to date have not
been significant.

</TABLE>
 
  SIX MONTHS ENDED FEBRUARY 28, 1997 COMPARED TO SIX MONTHS ENDED FEBRUARY 29,
    1996
 
    NET REVENUES.  Net revenues increased 46.3% to $31.3 million for the six
months ended February 28, 1997 as compared to $21.4 million for the six months
ended February 29, 1996. The increased net revenues reflect increased sales of
the Company's PortMaster 3 product and increased royalties, partially offset by
declining sales of the PortMaster 2 products. Royalty revenues were $4.0 million
and $963,000 for the six months ended February 28, 1997 and February 29, 1996,
respectively. Sales to international customers accounted for approximately 44.7%
of product revenues for the six months ended February 28, 1997 compared to 26.2%
for the prior year period.
 
    GROSS PROFIT.  The Company's gross profit for the six months ended February
28, 1997 increased to $17.4 million from $12.7 million for the six months ended
February 29, 1996. This increase was attributable to the introduction and
increased sales of the PortMaster 3 products and to increased royalties,
partially
 
                                       20
<PAGE>
offset by $2.0 million in charges for obsolete PortMaster 2 product and
component inventory. Gross margin on product revenues declined to 48.8% for the
six months ended February 28, 1997, compared to 57.6% for the comparable period
of 1996. The lower gross margin was due to the charge for obsolete PortMaster 2
inventory and due to approximately $840,000 reserved to provide the Company's
56K modem solution, upon request, for PortMaster 3 products sold during the
period.
 
    RESEARCH AND DEVELOPMENT.  Research and development expenses consist
primarily of compensation, amounts paid for outside services, and costs of
materials utilized in product development. Research and development expenses
increased to $1.9 million, or 5.9% of net revenues, during the six months ended
February 28, 1997, from $721,000, or 3.3% of net revenues, for the six months
ended February 29, 1996. This increase was due primarily to the addition of
personnel for the development of PortMaster 3, enhancement of the ComOS
operating system and development of future products. The Company believes that
significant research and development efforts are necessary in order for it to
compete in the evolving market for remote access products. Accordingly, the
Company expects its research and development expenditures to increase in
absolute dollars and as a percentage of net revenues.
 
    SELLING AND MARKETING.  Selling and marketing expenses consist primarily of
base and incentive compensation paid to sales, customer support and marketing
personnel, travel and related expenses, and costs associated with promotional
and trade show activities. Selling and marketing expenses increased to $6.4
million, or 20.5% of net revenues, for the six months ended February 28, 1997
from $3.4 million, or 16.1% of net revenues, for the six months ended February
29, 1996. The increase reflects significant hiring of direct sales personnel in
North America and Europe and technical support personnel in North America, as
well as increased incentive compensation due to increased sales volume. The
Company expects selling and marketing expenses to increase both in absolute
dollars and as a percentage of net revenues as the Company pursues its strategy
of expanding its direct sales force.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
primarily of compensation paid to administrative personnel and related overhead.
General and administrative expenses increased to $1.4 million, or 4.4% of net
revenues, for the six months ended February 28, 1997 from $544,000, or 2.5% of
net revenues, for the corresponding period in the prior year as the Company
continued to build its infrastructure to support growth in its manufacturing,
research and development, and selling and marketing functions. The Company
expects that general and administrative expenses will increase in absolute
dollars as the Company continues to expand its operations and incurs higher
administration expenses related to reporting and other requirements of a public
company.
 
    PROVISION FOR INCOME TAXES.  The Company's effective tax rate for the first
six months of fiscal 1997 was 40.0% compared to 39.6% in fiscal 1996. See Notes
1 and 4 of Notes to Consolidated Financial Statements.
 
  YEAR ENDED AUGUST 31, 1996 COMPARED TO THE YEAR ENDED AUGUST 31, 1995
 
    NET REVENUES.  Net revenues increased 125% to $46.1 million for fiscal 1996,
as compared to $20.5 million for fiscal 1995. This increase was due primarily to
higher sales of the Company's communication servers and routers. Royalty
revenues were $2.9 million and $323,000 in fiscal 1996 and fiscal 1995,
respectively. Sales to international customers accounted for 29.7% of product
revenues in fiscal 1996 compared to 16.9% in fiscal 1995. This increase in
international sales was the result of an expansion of the Company's reseller
relationships in Japan and Europe.
 
    GROSS PROFIT.  The Company's gross profit for fiscal 1996 increased to $27.5
million from $12.4 million for fiscal 1995. This increase was due primarily to
higher unit sales and increased royalties. Gross margin on product revenues
(excluding royalty revenues) declined to 57.0% in fiscal 1996 compared to 60.0%
in fiscal 1995 as a result of a charges of $1.3 million taken in the second half
of fiscal 1996 related to the Company's establishment of an inventory reserve in
connection with the PortMaster 2 product line.
 
                                       21

    RESEARCH AND DEVELOPMENT.  Research and development expenses increased to
$2.5 million, or 5.5% of net revenues, in fiscal 1996 compared to $890,000, or
4.3% of net revenues, in fiscal 1995, due primarily to the addition of personnel
for the development of the PortMaster 3 and for enhancements and feature
upgrades to ComOS. Research and development expenses in fiscal 1996 included
$632,000 for purchased in-process research and development, primarily related to
modem technology.
 
    SELLING AND MARKETING.  Selling and marketing expenses increased to $8.7
million, or 18.8% of net revenues, in fiscal 1996 compared to $2.8 million, or
13.8% of net revenues, in fiscal 1995. The increase was due primarily to
increased staffing levels in sales intended to broaden the geographic reach for
the Company's products, increased marketing expenses related to trade show
participation and development of collateral materials, and increased staffing of
technical support operations in response to a growing installed base of
products.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses increased
to $1.8 million, or 3.8% of net revenues, in fiscal 1996 compared to $667,000,
or 3.3% of net revenues, in fiscal 1995 due to increased personnel and overhead
costs and increased use of outside professional services as the Company began to
build its infrastructure to support growth in its manufacturing, research and
development, and selling and marketing functions.
 
    PROVISION FOR INCOME TAXES.  The Company's effective tax rate for fiscal
1996 was 39.7% compared to 38.7% in fiscal 1995.
 
  YEAR ENDED AUGUST 31, 1995 COMPARED TO THE YEAR ENDED AUGUST 31, 1994
 
    NET REVENUES.  Net revenues increased 231% to $20.5 million for fiscal 1995
from $6.2 million for fiscal 1994. This increase was due to an increase in unit
sales of PortMaster 2 products and router products. In fiscal 1995 royalty
revenues were $323,000.
 
    GROSS PROFIT.  The Company's gross profit for fiscal 1995 increased to $12.4
million from $3.3 million for fiscal 1994, due primarily to higher unit sales
and royalties from USR. Gross margin on product revenues increased to 60.0% in
fiscal 1995 from 53.8% in fiscal 1994. This increase was primarily due to
decreased component material costs related to increased volume purchases of
components.
 
    RESEARCH AND DEVELOPMENT.  Research and development expenses increased to
$890,000, or 4.3% of net revenues, in fiscal 1995 compared to $462,000, or 7.4%
of net revenues, in fiscal 1994. This increase primarily reflects increased
spending for consulting services.
 
    SELLING AND MARKETING.  Selling and marketing expenses increased to $2.8
million, or 13.8% of net revenues, in fiscal 1995 compared to $673,000, or 10.9%
of net revenues, in fiscal 1994. These increases reflect higher staffing levels
in sales, marketing, and technical service in order to develop the Company's
reseller channel domestically and internationally and to support a growing
installed product base.
 
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses were
$667,000, or 3.3% of net revenues, in fiscal 1995 compared to $449,000, or 7.3%
of net revenues, in fiscal 1994.
 
    PROVISION FOR INCOME TAXES.  The Company's effective tax for fiscal 1995 was
38.7% compared to 40.4% in fiscal 1994.

    Net revenues increased in each of the first three quarters of fiscal 1996
principally as a result of increased remote access unit shipments. Product
revenues declined in the fourth quarter of fiscal 1996 due primarily to the
decrease in sales of PortMaster 2 communication servers. The Company believes
that the decline in PortMaster 2 sales was due primarily to delays in purchasing
decisions by the Company's customers in anticipation of the introduction of
PortMaster 3. The Company commenced shipment of PortMaster 3 in the first
quarter of fiscal 1997, and sales of PortMaster 3 represented a majority of net
revenues in the second quarter of fiscal 1997. The Company does not expect
sequential quarterly growth in product revenues to continue at the same rate
experienced from the first to the second quarter of fiscal 1997.
 
    Royalties from USR increased from $538,000 in the first quarter of fiscal
1996 to $2.3 million in the first quarter of fiscal 1997, then declined to $1.8
million in the second quarter of fiscal 1997. The Company believes that its
royalty revenues from USR will terminate in fiscal 1998, if not sooner.
 
    Gross margin on product revenues has fluctuated on a quarterly basis
generally because of product mix. Gross margin on product revenues in the
quarter ended November 30, 1996 was adversely affected by a charge of
approximately $2.0 million related to the provision for obsolete and overstocked
product and component inventory due to the decline in PortMaster 2 sales, and
due to approximately $840,000 reserved for further upgrades to implement the
Company's 56K modem solution for PortMaster 3 products sold.
 
    Research and development expenses have generally increased in dollar amount
due to increased staffing and higher amounts spent on outside consulting. In the
quarter ended August 31, 1996, research and development expenses included
$632,000 for purchased in-process research and development, principally related
to modem technology. Selling and marketing expenses have increased in dollar
amount and as a percentage of net revenues reflecting increased personnel and
related expenses, spending for promotional expenses, travel expense, and costs
associated with opening new sales offices in North America and Europe. General
and administrative expenses have increased in dollar amount due to increased
personnel and related expenses and increased outside professional services. The
increase in general and administrative expenses in the quarter ended August 31,
1996 included a charge of approximately $117,000 related to a buy-out of the
Company's lease commitment for its previous headquarters facilities in
connection with the Company's move to its new, larger headquarters facility in
November 1996.
 
    The Company's future net revenues are difficult to predict. Although the
Company typically operates with some backlog, net revenues and operating results
in any quarter depend on the volume and timing of, and the ability to fulfill,
orders received within the quarter. In addition, due to the Company's
utilization of its reseller channel, the Company's net revenues in any period
are highly dependent upon the sales efforts and success of its resellers, which
are not within the Company's control. There can be no assurance that the
Company's resellers will give a high priority to the marketing of the Company's
products as compared to competitive products or alternative networking
solutions, or that the resellers will continue to carry the Company's products.
Further, the Company's strategy is to broaden its customer base by increasing
its direct sales force and there can be no assurance that this new sales force
and the resellers will be capable of achieving the Company's growth goals.
 
    The Company anticipates that quarterly operating results will fluctuate as a
result of a number of factors, including customers' capital spending cycles, the
timing of new product announcements by the Company or its competitors, changes
in pricing policies by the Company, its competitors or its suppliers, the
availability and cost of key components, and market acceptance of new and
enhanced versions of the Company's products. In addition, it is possible that in
some future quarter the Company's operating results may be below the
expectations of public market analysts and investors. In such event, the market
price of the Company's Common Stock would likely be materially adversely
affected. See "Risk Factors-- Unpredictable and Fluctuating Quarterly Operating
Results" and "--Possible Volatility of Stock Price."

LIQUIDITY AND CAPITAL RESOURCES
 
    Since inception, the Company has financed its operations primarily through
cash flows from operating activities. As of February 28, 1997, the Company's
principal sources of liquidity consisted of $7.3 million of cash and cash
equivalents and an unsecured $5 million line of credit. The line of credit bears
interest at the bank's prime rate and specifies financial and operating
covenants, including restrictions on the Company's ability to purchase its own
stock and a prohibition on payment of cash dividends. There have been no
borrowings under the line of credit.
 
    During the six months ended February 28, 1997, cash provided by operating
activities was $4.9 million compared to $3.2 million during the six months ended
February 29, 1996. The Company's operating activities in fiscal 1996, 1995 and
1994 provided cash flows of $3.4 million, $1.2 million, and $644,000,
respectively. Cash provided by operating activities during these periods was
attributable primarily to increases in net income, partially offset by increases
in accounts receivable and inventories. As of February 28, 1997, the Company's
working capital was $17.7 million, which included $9.6 million and $4.5 million
of accounts receivable and inventory, respectively.
 
    The Company's investing activities have consisted primarily of purchases of
property and equipment. Cash used in investing activities increased to $1.5
million in the six months ended February 28, 1997 from $197,000 in the six
months ended February 29, 1996 due primarily to purchases of furniture and
fixtures for the new headquarters facility which the Company moved into in
November 1996. Cash used in investing activities totaled $881,000, $348,000, and
$63,000 in fiscal 1996, 1995 and 1994, respectively.
 
    The Company expects to use approximately $2.5 million for capital
expenditures over the next twelve months. The Company believes that the net
proceeds from this offering, together with available funds, its existing bank
line of credit and cash flows expected to be generated from operations, will be
sufficient to meet its anticipated cash needs at least through fiscal 1998.

    Livingston is a leading provider of remote access networking solutions for
ISPs worldwide. Used by ISPs to connect their subscribers to the Internet, the
Company's remote access servers deliver high performance at a low price per
port, making them particularly well-suited for the intensely competitive ISP
market. The Company also provides office routers and firewall routers that are
resold by ISPs to corporate customers for Internet connectivity and other remote
access networking applications. The Company believes that more ISPs worldwide
use Livingston's remote access servers than those of any other vendor. Since the
introduction of its first remote access server in 1990, over 2,000 ISPs have
purchased the Company's remote access products. In November 1996, the Company
introduced the PortMaster 3 access concentrator, its next generation remote
access platform, which the Company believes positions it to better address the
needs of large ISPs and Telcos, and to maintain its leadership position with the
Company's established base of local and regional ISP customers. The Company's
goal is to be the leading supplier of technologically advanced and
cost-effective remote access solutions to ISPs worldwide.
 
INDUSTRY BACKGROUND AND MARKET
 
  GROWTH OF THE INTERNET AND INTERNET INFRASTRUCTURE
 
    The Internet has emerged as a global network enabling millions of
businesses, organizations and individuals to communicate, share information and
conduct business electronically. A network of networks, the Internet comprises
hundreds of publicly and commercially owned networks that communicate and share
traffic using a common, industry standard communications protocol suite called
TCP/IP. According to International Data Corporation, the number of Internet
World Wide Web users will increase to 163 million in 2000, from an estimated 35
million users in 1996.
 
    Individuals and corporate customers typically access the Internet through
ISPs which maintain networks offering Internet access through local points of
presence ("POPs"). A POP consists of telecommunications and internetworking
equipment connected to the Internet through high speed dedicated lines leased
from telecommunications providers or through Frame Relay or ATM service
connections. To accommodate the growing numbers of Internet users and their
bandwidth requirements, many ISPs are dramatically increasing investments in
networking infrastructure, particularly in the area of remote access equipment.
 
  REMOTE ACCESS EQUIPMENT AND THE MARKET FOR REMOTE ACCESS SOLUTIONS
 
    Internet subscribers connect to ISPs through remote access equipment, such
as access concentrators, communications servers and access routers, utilizing
analog or digital dial-up lines or leased line connections. The remote access
market is among the fastest growing segments in the networking industry.
Infonetics Research, Inc. forecasts that network product expenditures by ISPs
will increase from approximately $2.0 billion in 1996 to over $5.3 billion in
1998.
 
    As depicted on the following page, a dial-up subscriber communicates with an
ISP over a standard analog, ISDN or T1/E1 leased line connection. An access
concentrator, which contains multiple digital modems, or a communications server
with externally connected analog modems housed within the POP, receives the
subscriber's call, performs user authentication and billing functions, and
passes traffic through to the Internet via the ISP's router-based network. For
high speed communications, access routers located at the subscribers' premises
manage the exchange of Internet traffic between the ISP's network and the
subscribers' network over dedicated leased lines. Software operating with the
remote access hardware enables the ISP to perform critical functions such as
device and network management, subscriber administration, authorization and
accounting, firewall filtering and protocol routing.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The members of the Compensation Committee of the Board of Directors are Mr.
Pimentel and Mr. Hawk. No member of the Compensation Committee or executive
manager of the Company has a relationship that would constitute an interlocking
relationship with executive managers or directors of another entity.
 
LIMITATIONS ON DIRECTORS' LIABILITY AND INDEMNIFICATION
 
    The Company's Restated Articles of Incorporation include a provision that
eliminates the personal liability of its directors to the Company and its
shareholders for monetary damages for breach of the directors' fiduciary duties
in certain circumstances. This limitation has no effect on a director's
liability (i) for acts or omissions that involve intentional misconduct or a
knowing and culpable violation of law, (ii) for acts or omissions that a
director believes to be contrary to the best interest of the Company or its
shareholders or that involve the absence of good faith on the part of the
director, (iii) for any transaction from which a director derived an improper
personal benefit, (iv) for acts or omissions that show a reckless disregard for
the director's duty to the Company or its shareholders in circumstances in which
the director was aware, or should have been aware, in the ordinary course of
performing a director's duties, of a risk of a serious injury to the Company or
its shareholders, (v) for acts or omissions that constitute an unexcused pattern
of inattention that amounts to an abdication of the director's duty to the
Company or its shareholders, (vi) under Section 310 of the California
Corporations Code (the "California Code") concerning contracts or transactions
between the Company and a director or (vii) under Section 316 of the California
Code concerning directors' liability for improper dividends, loans and
guarantees. The provision does not affect the availability of injunctions and
other equitable remedies available to the Company's shareholders for any
violation of a director's fiduciary duty to the Company or its shareholders.
 
    The Company's Restated Articles of Incorporation also include an
authorization for the Company to indemnify its agents (as defined in Section 317
of the California Code), through bylaw provisions, by agreement or otherwise, to
the fullest extent permitted by law. Pursuant to this provision, the Company's
Bylaws provide for indemnification of the Company's directors, officers and
employees. In addition, the Company, at its discretion, may provide
indemnification to persons whom the Company is not obligated to indemnify. The
Bylaws also allow the Company to enter into indemnity agreements with individual
directors, officers, employees and other agents. These indemnity agreements have
been entered into with all directors and executive officers and provide the
maximum indemnification permitted by law. These agreements, together with the
Company's Bylaws and Articles of Incorporation, may require the Company, among
other things, to indemnify these directors or executive officers (other than for
liability resulting from willful misconduct of a culpable nature), to advance
expenses to them as they are incurred, provided that they undertake to repay the
amount advanced if it is ultimately determined by a court that they are not
entitled to indemnification, and to obtain directors' and officers' insurance if
available on reasonable terms. Section 317 of the California Code and the
Company's Bylaws make provision for the indemnification of officers, directors
and other corporate agents in terms sufficiently broad to indemnify such
persons, under certain circumstances, for liabilities (including reimbursement
of expense incurred) arising under the Securities Act.
 
    The Company, with the approval of the Board of Directors, intends to obtain
directors' and officers' liability insurance prior to the effectiveness of this
offering.

(1) Consists of stock options granted pursuant to the Company's 1994 Stock
    Option Plan. Mr. Sasek's option became exercisable immediately, subject to a
    right of repurchase which lapses according to a vesting schedule of 25% at
    the end of one year following the vesting commencement date as determined by
    the Board of Directors and 1/36 of the remaining amount per month
    thereafter, and Mr. Hess' option became exerciseable immediately, subject to
    a right of repurchase which lapses according to a vesting schedule of 20% at
    the end of one year following the vesting commencement date as determined by
    the Board of Directors and 1/48 of the remaining amount per month
    thereafter, as long as each optionee remains an employee with, consultant to
    or director of the Company. The maximum term of each option granted is ten
    years from the date of grant. The exercise price is equal to the fair market
    value of the stock on the date of grant as determined by the Board of
    Directors.
 
(2) Potential gains are net of the exercise price but before taxes associated
    with the exercise. The 5% and 10% assumed annual rates of compounded stock
    appreciation are mandated by the rules of the Securities and Exchange
    Commission and do not represent the Company's estimate or projection of the
    future Common Stock price. 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. This table does not take into account any appreciation in
    the price of the Common Stock from the date of grant to the date of this
    Prospectus, other than the columns reflecting assumed rates of appreciation
    of 5% and 10%.

STOCK PLANS
 
    1994 STOCK OPTION PLAN.  The Company's 1994 Stock Option Plan was adopted by
the Board of Directors on August 19, 1994. An aggregate of 3,000,000 of the
Company's Common Stock is reserved for issuance under the 1994 Stock Option
Plan. The 1994 Stock Option Plan provides for grants to employees (including
executive management and employee directors) of "incentive stock options" within
the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code"), and for grants to employees and consultants of nonstatutory stock
options. As of April 30, 1997, options to purchase a total of 2,538,380 shares
at a weighted average exercise price of $3.46 per share were outstanding, and
461,620 shares remained available for future option grants. The 1994 Stock
Option Plan may be administered by the Board of Directors or a committee of the
Board (the "Administrator"). The Administrator determines the terms of options
granted under the 1994 Stock Option Plan, including the number of shares subject
to the option, exercise price, term and the rate at which the options become
exercisable. Currently, each option that has been granted under the 1994 Plan is
immediately exerciseable, subject to a right of repurchase which lapses
according to a vesting schedule determined by the Administrator. The exercise
price of all incentive stock options granted under the 1994 Stock Option Plan
must be at least equal to the fair market value of the Common Stock of the
Company on the date of grant. The exercise price of all nonstatutory stock
options must equal at least 85% of the fair market value of the Common Stock on
the date of grant. The exercise price of any stock option granted to an optionee
who owns stock representing more than 10% of the voting power of all classes of
stock of the Company must equal at least 110% of the fair market value of the
Common Stock on the date of grant. The exercise price may be paid in cash or
pursuant to a loan or installment arrangement approved by the Board. With
respect to any participant who owns stock representing more than 10% of the
voting power of all classes of stock of the Company, the term of incentive stock
options are limited to five years or less. The term of all options may not
exceed ten years. If not terminated earlier by the Administrator, the 1994 Stock
Option Plan will terminate in 2004. The Administrator has the authority to amend
or terminate the 1994 Stock Option Plan as long as such action does not
adversely affect any outstanding option. In the event of a proposed sale of all
or substantially all of the Company's assets, or a merger of the Company with or
into another corporation, each option may be assumed or an equivalent option
substituted by the successor corporation (if any). Upon completion of this
offering, no further option grants will be made under the 1994 Stock Option
Plan.
 
    1997 STOCK PLAN.  The Company's 1997 Stock Plan was adopted by the Board of
Directors in May 1997 and will be submitted to shareholders for approval in May
1997. The 1997 Stock Plan provides for the grant of incentive stock options to
employees (including officers and directors) and for the grant of nonstatutory
stock options and stock purchase rights ("SPRs") to employees, directors and
consultants. A total of 1,500,000 shares of Common Stock has been reserved for
issuance under the 1997 Stock Plan plus any shares which have been reserved but
unissued under the 1994 Stock Option Plan. In addition, an annual increase in
the number of shares reserved will be added on each anniversary date of the
adoption of the 1997 Stock Plan equal to the lesser of (i) 600,000 shares, (ii)
4% of the outstanding shares on such date or (iii) a lesser amount determined by
the Board. Prior to this offering, there were no options or SPRs outstanding
under the 1997 Stock Plan.
 
    The 1997 Stock Plan may be administered by the Board of Directors or a
committee designated by the Board (the "Administrator"). Options and SPRs
granted under the 1997 Stock Plan are not generally transferable by the optionee
except by will or by the laws of descent and distribution, and are exercisable
during the lifetime of the optionee only by such optionee. Options granted under
the 1997 Stock Plan must be exercised within three months of the end of the
optionee's status as an employee, director or consultant of the Company, or
within twelve months after such optionee's death or disability, but in no event
later than the expiration of the option term. The exercise price of all
incentive and nonstatutory stock options granted under the 1997 Stock Plan shall
be determined by the Administrator. With respect to any participant who owns
stock possessing more than ten percent of the voting power of all classes of the
Company's outstanding capital stock (a "10% Stockholder"), the exercise price of
any incentive stock
 
                                       41
<PAGE>
option granted must equal at least 110% of the fair market value on the grant
date. The exercise price of incentive stock options and nonstatutory stock
options for all other employees shall be no less than 100% of the fair market
value per share on the date of grant. The maximum term of an option granted
under the 1997 Stock Plan may not exceed ten years from the date of grant (five
years in the case of an incentive stock option granted to a 10% stockholder). In
the case of SPRs, unless the Administrator determines otherwise, the Company
shall have a repurchase option exercisable upon the voluntary or involuntary
termination of the purchaser's employment with the Company for any reason
(including death or disability). Such repurchase option lapses at a rate
determined by the Administrator. The purchase price for shares repurchased by
the Company shall be the original purchase price paid by the purchaser and may
be paid by cancellation of any indebtedness of the purchaser to the Company. In
the event of a merger or sale of substantially all of the assets of the Company,
the acquiring or successor corporation must either assume the outstanding
options and SPRs under the 1997 Stock Plan or substitute equivalent options or
SPRs to purchase shares of the acquiring or successor corporation (or a parent
or subsidiary of the acquiring or successor corporation). If an employee is
involuntarily terminated by the acquiring or successor corporation within twelve
months of the merger or asset sale (other than for cause), or if such acquiring
or successor corporation refuses to substitute or assume outstanding options or
SPRs, the employee's options and SPRs fully vest and become immediately
exercisable.
 
    1997 EMPLOYEE STOCK PURCHASE PLAN.  The Company's 1997 Employee Stock
Purchase Plan (the "Stock Purchase Plan") was adopted by the Board of Directors
in May 1997 and will be submitted to the shareholders for approval in May 1997.
The Company has reserved a total of 500,000 shares of Common Stock for issuance
under the Stock Purchase Plan, plus an annual increase to be added on each
anniversary date of the adoption of the Stock Purchase Plan equal to the lesser
of (i) 150,000 shares, (ii) 1% of the outstanding shares on such date or (iii) a
lesser amount determined by the Board. The Stock Purchase Plan, which is
intended to qualify under Section 423 of the Internal Revenue Code of 1986, as
amended (the "Code"), permits eligible employees of the Company to purchase
shares of Common Stock through payroll deductions of up to ten percent (10%) of
their compensation, up to a maximum of $25,000 worth of Common Stock (valued at
the date of grant) in each calendar year. The Stock Purchase Plan will be
implemented by consecutive overlapping 24-month offering periods (each an
"Offering Period"). The initial Offering Period will begin on the effective date
of this offering and will end on the last trading day in the period ending March
31, 1999. All employees who work at least twenty hours per week and more than
five months per calendar year are eligible to participate in the Stock Purchase
Plan.
 
    The price of Common Stock purchased under the Stock Purchase Plan will be
85% of the lower of the fair market value of the Common Stock on the first day
of each Offering Period or the date of purchase. Employees may withdraw from the
Stock Purchase Plan at any time during an Offering Period, and the balance of
the payroll deductions will be returned to the employee. Participation in the
Stock Purchase Plan ends automatically upon termination of employment with the
Company. Rights granted under the Stock Purchase Plan are not transferable by a
participant other than by will, the laws of descent and distribution or as
otherwise provided under the Stock Purchase Plan.
 
    The Stock Purchase Plan will be administered by the Board of Directors or by
a committee appointed by the Board. The Board may amend or modify the Stock
Purchase Plan at any time. The Stock Purchase Plan will terminate ten years
after the effective date of its adoption, unless sooner terminated by the Board.
 
SECTION 401(k) PLAN
 
    In September 1995, the Board approved the Livingston Retirement Savings Plan
(the "401(k) Plan"), covering the Company's full-time employees located in the
United States. Pursuant to the 401(k) Plan, employees may elect to reduce their
current compensation by up to the statutorily prescribed annual limit ($9,500 in
calendar years 1996 and 1997) and to have the amount of such reduction
contributed to the 401(k) Plan. The 401(k) Plan permits, but does not require,
additional matching contributions to the
 
                                       42
<PAGE>
401(k) Plan by the Company on behalf of all participants in the 401(k) Plan. The
Company has not made any contributions to the 401(k) Plan. The 401(k) Plan is
intended to qualify under Section 401(k) of the Code, such that contributions to
the 401(k) Plan by employees or by the Company, and the investment earnings
thereon, are not taxable to employees until withdrawn from the 401(k) Plan, and
such that contributions by the Company, if any, will be deductible by the
Company.

                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized capital stock of the Company consists of 30,000,000 shares of
Common Stock. The following summaries of certain provisions of the Common Stock
do not purport to be complete, are subject to, and qualified in their entirety
by, the provisions of the Company's Amended and Restated Articles of
Incorporation (the "Restated Articles"), which is included as an exhibit to the
Registration Statement of which this Prospectus forms a part, and by applicable
law.
 
COMMON STOCK
 
    As of April 30, 1997, there were 12,370,272 shares of Common Stock
outstanding, which were held of record by 58 shareholders. The holders of Common
Stock are entitled to one vote per share on all matters to be voted upon by the
shareholders. The holders of Common Stock are entitled to receive ratably such
dividends, if any, as may be declared from time to time by the Board of
Directors out of funds legally available for that purpose. See "Dividend
Policy." In the event of a liquidation, dissolution or winding up of the
Company, the holders of Common Stock are entitled to share ratably in all assets
remaining after payment of liabilities. Holders of Common Stock have no
preemptive or conversion rights or other subscription rights. There are no
redemption or sinking fund provisions applicable to the Common Stock. All
outstanding shares of Common Stock are fully paid and non-assessable, and the
shares of Common Stock to be issued upon the closing of this offering will be
fully paid and non-assessable.
 
PREFERRED STOCK
 
    The Board of Directors has approved an amendment to the Restated Articles
which authorizes the issuance of up to 5,000,000 shares of Preferred Stock in
one or more series and to fix the designations, powers, preferences and
privileges, and relative participating, optional or special rights and the
qualifications, limitations or restrictions thereof, including dividend rights,
conversion rights, voting rights, terms of redemption and liquidation
preferences, any or all of which may be greater than the rights of the Common
Stock. Subject to approval of such amendment by the shareholders, and effective
upon the filing of the Restated Articles, the Board of Directors, without
further shareholder approval, can issue Preferred Stock with voting, conversion
or other rights that could adversely affect the voting power and other rights of
holders of Common Stock. Preferred Stock could thus be issued quickly with terms
calculated to delay, or prevent a change in control of the Company or make
removal of management more difficult. Additionally, the issuance of Preferred
Stock may have the effect of decreasing the market price of the Common Stock,
and may adversely affect the voting and the other rights of the holders of
Common Stock. At present, there are no shares of Preferred Stock outstanding and
the Company has no plans to issue any of the Preferred Stock.
 
CALIFORNIA LAW AND CERTAIN PROVISIONS
 
    Certain provisions of California law and the Company's Restated Articles of
Incorporation and Bylaws, could make more difficult the removal of incumbent
officers and directors and the acquisition of the Company by means of a tender
offer, a proxy contest or otherwise. Upon qualification of the Company as a
"listed corporation," as defined in Section 301.5(d) of the California Code,
cumulative voting will be eliminated and the Board of Directors will be divided
into two classes of directors, serving staggered two-year terms. At each annual
meeting, one class of directors will be elected for a two-year term. See
"Management." These provisions are expected to discourage certain types of
coercive takeover practices and inadequate takeover bids and to encourage
persons seeking to acquire control of the Company to negotiate first with the
Company. The Company believes that the benefits of increased protection of the
Company's potential ability to negotiate with the proponent of an unfriendly or
unsolicited proposal to acquire or restructure the Company outweigh the
disadvantages of discouraging such proposals because, among other things,
negotiation of such proposals could result in an improvement of their terms.
 
TRANSFER AGENT AND REGISTRAR
 
    The transfer agent and registrar for the Common Stock is ChaseMellon
Shareholder Services, L.L.P. of San Francisco, California. Its telephone number
is (415) 954-9512.

<PAGE>
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this offering, there has been no public market for the Common Stock
of the Company. Future sales of substantial amounts of Common Stock in the
public market could adversely affect prevailing market prices from time to time.
Furthermore, since only a limited number of shares will be available for sale
shortly after this offering because of certain contractual and legal
restrictions on resale (as described below), sales of substantial amounts of
Common Stock of the Company in the public market after the restrictions lapse
could adversely affect the prevailing market price and the ability of the
Company to raise equity capital in the future.
 
    Upon completion of this offering the Company will have outstanding an
aggregate of         shares of Common Stock (based upon shares outstanding at
April 30, 1997), assuming no exercise of the Underwriters' over-allotment option
and no exercise of outstanding options. Of these shares, all of the shares sold
in this offering will be freely tradeable without restriction or further
registration under the Securities Act, unless such shares are purchased by
"affiliates" of the Company as that term is defined in Rule 144 under the
Securities Act. The remaining 12,370,272 shares of Common Stock held by existing
stockholders are "restricted securities" as that term is defined in Rule 144
under the Securities Act ("Restricted Shares"). Restricted Shares may be sold in
the public market only if registered or if they qualify for an exemption from
registration under Rules 144 or 701 promulgated under the Securities Act, which
rules are summarized below. As a result of the contractual restrictions
described below and the provisions of Rules 144 and 701, the Restricted Shares
will be available for sale in the public market as follows: (i) no shares will
be eligible for immediate sale on the date of this Prospectus, (ii) 33,000
shares will be eligible for sale beginning 90 days after the date of this
Prospectus, and (iii) 12,337,272 shares will be eligible for sale upon
expiration of the lock-up agreements 180 days after the date of this Prospectus.
 
    All officers, directors and certain stockholders of the Company have agreed
not to offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase, or otherwise transfer or dispose of, directly or indirectly
(or enter into any swap or other arrangement that transfers to another, in whole
or in part, any of the economic consequences of ownership of), any shares of
Common Stock or any securities convertible into or exercisable or exchangeable
for shares of Common Stock, for a period of 180 days after the date of this
Prospectus, without the prior written consent of Morgan Stanley & Co.
Incorporated.
 
    In general, under Rule 144, beginning 90 days after the date of this
Prospectus, a person (or persons whose shares are aggregated) who has
beneficially owned Restricted Shares for at least one year (including the
holding period of any prior owner except an Affiliate) would be entitled to sell
within any three-month period a number of shares that does not exceed the
greater of: (i) one percent of the number of shares of Common Stock then
outstanding (which will equal approximately         shares immediately after
this offering); or (ii) the average weekly trading volume of the Common Stock on
the Nasdaq National Market during the four calendar weeks preceding the filing
of a notice on Form 144 with respect to such sale. Sales under Rule 144 are also
subject to certain manner of sale provisions and notice requirements and to the
availability of current public information about the Company. Under Rule 144(k),
a person who is not deemed to have been an Affiliate of the Company at any time
during the 90 days preceding a sale, and who has beneficially owned the shares
proposed to be sold for at least two years (including the holding period of any
prior owner except an Affiliate), is entitled to sell such shares without
complying with the manner of sale, public information, volume limitation or
notice provisions of Rule 144; therefore, unless otherwise restricted, "144(k)
shares" may therefore be sold immediately upon the completion of this offering.
In general, under Rule 701 of the Securities Act as currently in effect, any
employee, consultant or advisor of the Company who purchases shares from the
Company in connection with a compensatory stock or option plan or other written
agreement is eligible to resell such shares 90 days after the effective date of
this offering in reliance on Rule 144, but without compliance with certain
restrictions, including the holding period, contained in Rule 144.

    The Company intends to file a registration statement under the Securities
Act covering shares of Common Stock reserved for issuance under the Company's
1994 Stock Option Plan, 1997 Stock Plan and Stock Purchase Plan. See
"Management--Stock Plans." Such registration statement is expected to be filed
and become effective as soon as practicable after the effective date of this
offering. Accordingly, shares registered under such registration statement will,
subject to Rule 144 volume limitations applicable to Affiliates, be available
for sale in the open market, unless such shares are subject to vesting
restrictions with the Company or the lock-up agreements described above. As of
April 30, 1997, options to purchase 2,538,380 shares of Common Stock were issued
and outstanding under the 1994 Stock Option Plan, and no options to purchase
shares had been granted under the Company's 1997 Stock Plan and Stock Purchase
Plan.

    The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of Common Stock
offered hereby are subject to the approval of certain legal matters by their
counsel and to certain other conditions. The Underwriters are obligated to take
and pay for all of the shares of Common Stock offered hereby (other than those
covered by the Underwriters' over-allotment option described below) if any such
shares are taken.
 
    The Underwriters initially propose to offer part of the shares of Common
Stock offered hereby directly to the public at the initial public offering price
set forth on the cover page hereof and part to certain dealers at a price which
represents a concession not in excess of $    per share under the initial public
offering price. The Underwriters may allow, and such dealers may re-allow, a
concession not in excess of $    per share to other Underwriters or to certain
other dealers. After the initial offering of the shares of Common Stock, the
offering price and other selling terms may from time to time be varied by Morgan
Stanley & Co. Incorporated.
 
    Pursuant to the Underwriting Agreement, the Company and certain of the
Selling Shareholders have granted to the Underwriters an option, exercisable for
30 days from the date of this Prospectus, to purchase up to an aggregate of
      additional shares of Common Stock, at the public offering price set forth
on the cover page hereof, less underwriting discounts and commissions. The
Underwriters may exercise such option to purchase solely for the purpose of
covering over-allotments, if any, made in connection with the offering of the
shares of Common Stock offered hereby. To the extent such option is exercised,
each Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of such additional shares of Common
Stock as the number set forth next to such Underwriter's name in the preceding
table bears to the total number of shares of Common Stock set forth next to the
names of all Underwriters in the preceding table.
 
    In order to facilitate the offering of the Common Stock, the Underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the Common Stock. Specifically, the Underwriters may overallot in
connection with the offering, creating a short position in the Common Stock for
their own
 
                                       49
<PAGE>
account. In addition, to cover overallotments or to stabilize the price of the
Common Stock, the Underwriters may bid for, and purchase, shares of Common Stock
in the open market. Finally, the underwriting syndicate may reclaim selling
concessions allowed to an underwriter or a dealer for distributing the Common
Stock in the offering, if the syndicate repurchases previously distributed
Common Stock in transactions to cover syndicate short positions, in
stabilization transactions or otherwise. Any of these activities may stabilize
or maintain the market price of the Common Stock above independent market
levels. The Underwriters are not required to engage in these activities, and may
end any of these activities at any time.
 
    The Underwriters have informed the Company that they do not intend sales to
discretionary accounts to exceed five percent of the total number of shares of
Common Stock offered by them.
 
    The Company, the Selling Shareholders and the Underwriters have agreed to
indemnify each other against certain liabilities, including liabilities under
the Securities Act.
 
    Each of the Company and the directors, executive officers and certain other
stockholders of the Company has agreed that, without the prior written consent
of Morgan Stanley & Co. Incorporated on behalf of the Underwriters, it will not
(i) offer, pledge, sell, contract to sell, sell any option or contract to
purchase, purchase any option or contract to sell, grant any option, right or
warrant to purchase or otherwise transfer or dispose of, directly or indirectly,
any shares of Common Stock or any securities convertible into or exercisable or
exchangeable for Common Stock or (ii) enter into any swap or other arrangement
that transfers to another, in whole or in part, any of the economic consequences
of ownership of the Common Stock, whether any such transaction described in
clause (i) or (ii) above is to be settled by delivery of Common Stock or such
other securities, in cash or otherwise, during the period ending 180 days after
the date of this Prospectus, other than (x) the Shares and (y) the issuance by
the Company of shares of Common Stock upon the exercise of an option or a
warrant or the conversion of a security outstanding on the date of this
Prospectus of which the Underwriters have been advised in writing.
 
    The Underwriters have reserved up to     shares of Common Stock for sale at
the initial public offering price to certain persons associated with the
Company, as such persons have expressed an interest in purchasing such shares of
Common Stock in the Offering. The number of shares available for sale to the
general public will be reduced to the extent such persons purchase such reserved
shares. Any reserved shares not so purchased will be offered by the Underwriters
to the general public on the same basis as the other shares offered hereby.
 
PRICING OF THE OFFERING
 
    Prior to the Offering, there has been no public market for the Common Stock
of the Company. The initial public offering price for the Common Stock was
determined by negotiations among the Company, representatives of the Selling
Shareholders and the Representatives of the Underwriters. Among the factors to
be considered in determining the initial public offering price will be the
future prospects of the Company and its industry in general, sales, earnings and
certain other financial and operating information of the Company in recent
periods, and the price-earnings ratios, price-sales ratios, market prices of
securities and certain financial and operating information of companies engaged
in activities similar to those of the Company.

                         REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
 
Livingston Enterprises, Inc.
 
    We have audited the accompanying consolidated balance sheets of Livingston
Enterprises, Inc. and subsidiaries as of August 31, 1995 and 1996, and the
related consolidated statements of operations, shareholders' equity, and cash
flows for each of the years in the three-year period ended August 31, 1996.
These consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Livingston
Enterprises, Inc. and subsidiaries at August 31, 1995 and 1996, and the results
of operations and its cash flows for each of the years in the three-year period
ended August 31, 1996 in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
      (INFORMATION RELATING TO THE SIX MONTHS ENDED FEBRUARY 29, 1996 AND
                        FEBRUARY 28, 1997 IS UNAUDITED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
THE COMPANY
 
    Livingston Enterprises, Inc. (the Company), a California corporation, is a
provider of integrated remote access networking solutions for Internet Service
Providers.
 
BASIS OF CONSOLIDATION
 
    The accompanying consolidated financial statements include the accounts of
the Company and its subsidiaries from which intercompany accounts and
transactions have been eliminated.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS
 
    The Company considers all highly liquid investments with remaining
maturities of three months or less at time of acquisition to be cash
equivalents.
 
    The Company accounts for cash equivalents and short-term investments in
accordance with Statement of Financial Accounting Standards (SFAS) No. 115,
ACCOUNTING FOR CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES. All cash and
cash equivalents are classified as available-for-sale under the provisions of
SFAS No. 115. The securities are carried at cost which approximates fair value
and any unrealized gains or losses, net of taxes, would be reported as a
separate component of shareholders' equity.
 
REVENUE RECOGNITION
 
    The Company recognizes revenues from sales of remote access products upon
shipment. The Company grants its value-added resellers limited rights to
exchange products and price protection on unsold merchandise. The Company
establishes an estimated allowance for future product returns based on
historical returns experience and provides for appropriate price protection
reserves at the time the related revenue is recorded. To date, returns for
exchange and amounts granted from price protection have not been significant.
 
    The Company accounts for revenue related to the software portion of their
product in accordance with Statement of Position 91-1, SOFTWARE REVENUE
RECOGNITION. Postcontract customer support ("PCS") revenues generally are
recognized ratably over the term of the support period (generally one year). PCS
revenues to date have not been significant and are included in product revenues.
The unamortized portion of PCS is reported as deferred revenue.
 
    The Company records royalty revenue at the time the amount is determinable
and collection is certain.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
      (INFORMATION RELATING TO THE SIX MONTHS ENDED FEBRUARY 29, 1996 AND
                        FEBRUARY 28, 1997 IS UNAUDITED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
INVENTORIES
 
    Inventories are valued using standard costs, which approximate the lower of
cost or market using the first-in, first-out method.
 
PROPERTY AND EQUIPMENT
 
    Property and equipment are recorded at cost and are depreciated using the
straight-line method over the estimated useful lives of the assets, generally
three to five years. Leasehold improvements are amortized using the
straight-line method over the estimated useful life of the assets or related
lease term, whichever is shorter.
 
    The Company adopted the provisions of SFAS No. 121, ACCOUNTING FOR THE
IMPAIRMENT OF LONG-LIVED ASSETS AND FOR LONG-LIVED ASSETS TO BE DISPOSED OF, on
September 1, 1996. SFAS No. 121 requires that long-lived assets and certain
identified intangibles be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows expected
to be generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceed the fair value of the assets. Assets to be disposed
of are reported at the lower of the carrying amount or fair value less costs to
sell. Adoption of this statement did not have a material impact on the Company's
financial position, results of operations, or liquidity.
 
RESEARCH AND DEVELOPMENT COSTS
 
    Research and development expenditures are generally charged to operations as
incurred. SFAS No. 86, ACCOUNTING FOR THE COSTS OF COMPUTER SOFTWARE TO BE SOLD,
LEASED OR OTHERWISE MARKETED, governs accounting for software development costs.
This statement provides for the capitalization of certain software development
costs once technological feasibility is established. The cost capitalized is
then amortized on a straight-line basis over the estimated product life, or
using the ratio of current revenue to total projected product revenues,
whichever is greater. To date, software development costs incurred subsequent to
the establishment of technological feasibility have not been material. Included
in research and development expense in fiscal 1996 is approximately $632,000
principally related to modem technology acquired in exchange for 18,000 shares
of common stock and $443,000 in cash.
 
CONCENTRATION OF CREDIT RISK
 
    Financial instruments that potentially subject the Company to concentrations
of credit risk consist principally of cash and cash equivalents and trade
receivables. Cash and cash equivalents consist of deposits with a major U.S.
commercial bank. The Company sells its products primarily to Internet Service
Providers through resellers. To reduce its credit risk, the Company performs
ongoing credit evaluations of its customers and maintains an allowance for
doubtful accounts to cover any credit losses. At February 28, 1997, $1.8 million
of royalty revenues remained outstanding.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
      (INFORMATION RELATING TO THE SIX MONTHS ENDED FEBRUARY 29, 1996 AND
                        FEBRUARY 28, 1997 IS UNAUDITED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying amounts of cash, cash equivalents, accounts receivable,
accounts payable, and accrued liabilities approximate fair values due to the
short maturity of the instruments.
 
PRODUCT RELATED COSTS
 
    Product related costs consist of warranty costs, modem technology license
fees, and costs related to the Company's 56K Modem Swap Program. This program
allows customers to upgrade to 56K modem technology as it becomes available at
no charge to them. The Company provides for all of the above costs at the time
revenue is recognized.
 
INCOME TAXES
 
    The Company accounts for income taxes in accordance with SFAS No. 109,
ACCOUNTING FOR INCOME TAXES. SFAS No. 109 prescribes an asset and liability
approach that results in the recognition of deferred tax assets and liabilities
for the expected future tax consequences of events that have been recognized in
the Company's consolidated financial statements or tax returns. In estimating
future tax consequences, SFAS No. 109 generally considers all expected future
events other than enactment of changes in tax laws or rates.
 
INTERIM ACCOUNTING
 
    The financial statements at February 28, 1997 and for the six months ended
February 29, 1996 and February 28, 1997 include all adjustments (consisting only
of normal adjustments) that management considers necessary for a fair
presentation of its financial position at such date and its operating results
and cash flows for those periods. Results for interim periods are not
necessarily indicative of results for the entire year.
 
    Income taxes for the six months ended February 29, 1996 and February 28,
1997 have been provided based on an estimate of the Company's effective tax rate
for fiscal 1996 and 1997.
 
PER SHARE INFORMATION
 
    Net income per share is computed using the weighted average number of common
shares and common share equivalents outstanding during the periods presented.
Common share equivalents result from the dilutive effect of outstanding options
to purchase common stock. Pursuant to the requirements of the Securities and
Exchange Commission (SEC), common shares issued by the Company during the twelve
months immediately preceding the initial public offering, plus the number of
equivalent shares resulting from options granted during this period, have been
included in the calculation of the shares used in computing net income per share
as if they were outstanding for all periods presented (using the treasury stock
method and the estimated public offering price).
 
    The Financial Accounting Standards Board recently issued SFAS No. 128,
EARNINGS PER SHARE, which requires the presentation of basic earnings per share
(EPS) and, for companies with potentially dilutive securities, such as
convertible debt, options, and warrants, diluted EPS. SFAS No. 128 is effective
for

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
annual and interim periods ending after December 31, 1997. The Company expects
that basic EPS will be higher than primary EPS as presented in the accompanying
consolidated financial statements and that diluted EPS will not differ
materially from fully diluted EPS as presented in the accompanying consolidated
financial statements.
 
STOCK COMPENSATION PLANS
 
    In October 1995, the Financial Accounting Standards Board issued SFAS No.
123, ACCOUNTING FOR STOCK BASED COMPENSATION. The Company adopted SFAS No. 123
in September 1996. The Company will continue to account for employee stock
options in accordance with Accounting Principles Board Opinion No. 25 and has
adopted the "disclosure only" alternative described in SFAS No. 123. The Company
expects that the adoption of this statement will not have a material effect on
the financial position or results of operations.
 
RECLASSIFICATIONS
 
    Certain amounts in the accompanying 1994 and 1995 consolidated financial
statements have been reclassified to conform with the 1996 consolidated
financial statement presentation.

5. SHAREHOLDERS' EQUITY
 
    In March 1996, the Company restated its Articles of Incorporation cancelling
its authorized Preferred Stock and the shareholders approved a three for one
stock split. Common Share and per share data in these consolidated financial
statements have been retroactively adjusted to reflect the stock split. The
Company has reserved 3,000,000 shares of common stock for issuance under the
1994 Stock Option Plan (the 1994 Plan). The 1994 Plan provides for incentive and
non-statutory stock options to be granted to employees (including officers),
directors, consultants, and other independent contractors.
 
    Stock options are granted at prices of not less than 85% of the fair market
value of the common stock at the time of grant, except that stock options
granted to any employee who owns stock representing more than 10% of total
combined voting power of all classes of the Company's capital stock must have an
exercise price of not less than 110% of fair market value. Shares available for
purchase on the exercise of options generally vest at a rate of 20% in the first
year and thereafter at a rate of 1/48 per each month the optionee is employed or
acts as a consultant of the Company. Options expire ten years from the date of

    In connection with options granted on February 21, 1997, the Company has
recorded deferred compensation expense of $568,000 for the difference between
the option grant price and the deemed fair value of the Company's common stock
at the date of grant. The amount is being amortized over the vesting period of
the individual options, generally a 60 month period. No deferred compensation
expense was recognized for the six months ended February 28, 1997.

9. RETIREMENT SAVINGS PLAN
 
    The Company sponsors a 401(k) defined contribution benefit plan that covers
all employees who have completed at least three months of service. This plan
allows for employees to defer up to 15% of their pretax salary in certain
investments at the discretion of the employees. The Company has the option to
make discretionary employer contributions, however, no such contributions have
been made since inception of the plan.
 
10. SUBSEQUENT EVENTS
 
    On May 9, 1997, the Board of Directors approved:
 
    - the Company's 1997 Stock Plan (the 1997 Plan), subject to shareholder
      approval. The Company reserved 1,500,000 shares of common stock for
      issuance under the 1997 Plan which provides for grants of stock options
      and stock purchase rights to employees, consultants, non-employee
      directors, and any parent or subsidiary of the Company. Options and rights
      are granted at prices equal to the fair market value of the common stock
      at the time of grant. Other conditions of the 1997 Plan are substantially
      the same as those of the 1994 Plan. No options or purchase rights have
      been granted under the 1997 Plan to date.
 
    - Board of Directors approved (effective upon the closing of the Company's
      initial public offering) the 1997 Employee Stock Purchase Plan (the
      "Purchase Plan"), subject to shareholder approval. Under the Purchase
      Plan, eligible employees may purchase common shares during six month
      payment periods commencing November 1 and May 1 of each year at a price
      per share of 85% of the lower of the average market price per share on the
      first or last business day of the six-month period. Participating
      employees may elect to have up to 10% of regular pay withheld and applied
      toward the purchase of such share up to a maximum of 10,000 shares in any
      six-month period. An employee's rights under the Purchase Plan terminate
      upon voluntary withdrawal from the Purchase Plan at any time or upon
      termination of employment. The Company has reserved 500,000 shares of
      common stock for issuance under the Purchase Plan. No shares have been
      issued to date.
 
    - An amendment to the Articles of Incorporation to increase authorized
      common stock to 100,000,000 shares and upon completion of the Company's
      initial public offering to increase authorized preferred stock to
      5,000,000 shares.
 
    Also, on May 9, 1997, the Company's Board of Directors authorized management
    of the Company to file a Registration Statement with the SEC permitting the
    Company to sell shares of its common stock to the public.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Bylaws of the Company provide for the indemnification of the Company's
officers and directors against certain liabilities and expenses relating to
lawsuits and other proceedings in which they may become involved. Section 317 of
the California Corporations Code also provides for indemnification of a
corporation's directors and officers under certain circumstances.
 
    Section 204(a)(10) and (11) and Section 317 of the California Corporations
Code and the Bylaws of the Company contain provisions covering indemnification
of corporate directors and officers against certain liabilities and expenses
incurred as a result of proceedings involving such persons in their capacities
as directors and officers, including proceedings under the Securities Act or the
Exchange Act.
 
    The Company provides indemnity insurance pursuant to which its directors and
officers are indemnified or insured under certain circumstances against certain
liabilities or losses, including liabilities under the Securities Act. The
Company has obtained shareholder approval to enter into indemnity agreements
with their respective directors and officers. Each agreement provides for
indemnification of the fines, settlements and other amounts incurred by such
person in connection with the good faith performance of his or her duties as a
director or officer. The indemnification agreements also provide for the advance
payment by the Company of expenses incurred in defending any proceeding to which
the director or officer may be a party, provided that the affected director or
officer executed an undertaking, acceptable to the disinterested members of the
board of directors, agreeing to repay all amounts advanced for defense of the
proceeding if it shall be ultimately determined that such director or officer
was not entitled to be indemnified in accordance with Sections 204(a)(10) and
(11) and Section 317 of the California Corporations Code.
 
    The Company understands that the staff of the Commission is of the opinion
that statutory, charter and contractual provisions as are described above have
no effect on claims arising under the federal securities laws.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES
 
    Since 1994 the registrant has issued and sold the following unregistered
securities: as of April 30, 1997, the Registrant has issued and sold 186,832
shares of Common Stock to employees and consultants at prices
 
                                      II-1
<PAGE>
ranging from $.033 to $10.50 per share, upon exercise of stock options, pursuant
to the Registrant's 1994 Stock Option Plan; in December 1995, the Company issued
15,000 shares of Common Stock to Douglas Meltzer in consideration of past
services rendered to the Company and the signing of a confidentiality agreement;

of $189,000 as determined by the Company's Board of Directors, of Lloyd
Internetworking, Inc. ("Lloyd") in June 1996, the Company issued 18,000 shares
of Common Stock to Lloyd shareholders.
 
    The sales of the above securities were deemed to be exempt from registration
under the Securities Act in reliance on Section 4(2) of the Securities Act, or
Rule 701 promulgated under Section 3(b) of the Securities Act, as transactions
by an issuer not involving a public offering or transactions pursuant to
compensatory benefit plans and contracts relating to compensation as provided
under such Rule 701. The recipients of securities in each such transaction
represented their intention to acquire the securities for investment only and
not with a view to or for sale in connection with any distribution thereof and
appropriate legends were affixed to the share certificates and instruments
issued in such transaction. All recipients had adequate access, through their
relationships with the Company, to information about the Registrant.

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

Dear Sirs and Mesdames:

         Livingston Enterprises, Inc., a California corporation (the 
"Company"), proposes to issue and sell to the several Underwriters named in 
Schedule II hereto (the "Underwriters"), and certain shareholders of the 
Company (the "Selling Shareholders") named in Schedule I hereto severally 
propose to sell to the several Underwriters, an aggregate of  _______________ 
shares of the Common Stock, no par value, of the Company (the "Firm Shares").

         The Company also proposes to issue and sell to the several 
Underwriters not more than an additional ______________ shares of its Common 
Stock, no par value, of which _____________ shares are to be issued and sold 
by the Company and _____________ shares are to be sold by the Selling 
Shareholders, each Selling Shareholder selling the amount set forth opposite 
such Selling Shareholder's name in Schedule I hereto (the "Additional 
Shares") if and to the extent that you, as Managers of the offering, shall 
have determined to exercise, on behalf of the Underwriters, the right to 
purchase such shares of common stock granted to the Underwriters in Section 3 
hereof.  The Firm Shares and the Additional Shares are hereinafter 
collectively referred to as the "Shares."  The shares of Common Stock, no par 
value, of the Company to be outstanding after giving effect to the sales 
contemplated hereby are hereinafter referred to as the "Common

                                      1

<PAGE>

Stock."  The Company and the Selling Shareholders are hereinafter sometimes 
collectively referred to as the "Sellers."

         The Company has filed with the Securities and Exchange Commission 
(the "Commission") a registration statement, including a prospectus, relating 
to the Shares.  The registration statement as amended at the time it becomes 
effective, including the information (if any) deemed to be part of the 
registration statement at the time of effectiveness pursuant to Rule 430A 
under the Securities Act of 1933, as amended (the "Securities Act"), is 
hereinafter referred to as the "Registration Statement"; the prospectus in 
the form first used to confirm sales of Shares is hereinafter referred to as 
the "Prospectus." If the Company has filed an abbreviated registration 
statement to register additional shares of Common Stock pursuant to Rule 
462(b) under the Securities Act (the "Rule 462 Registration Statement"), then 
any reference herein to the term "Registration Statement" shall be deemed to 
include such Rule 462 Registration Statement.

         As part of the offering contemplated by this Agreement, Morgan 
Stanley & Co. Incorporated ("Morgan Stanley") has agreed to reserve out of 
the Shares set forth opposite its name on Schedule II to this Agreement, up

heading "Underwriting" (the "Directed Share Program").  The Shares to be sold 
by Morgan Stanley pursuant to the Directed Share Program (the "Directed 
Shares") will be sold by Morgan Stanley pursuant to this Agreement at the 
public offering price.  Any Directed Shares not orally confirmed for purchase 
by any Participants by the end of the first business day after the date on 
which this Agreement is executed will be offered to the public by Morgan 
Stanley as set forth in the Prospectus.

         1.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY AND THE CHIEF 
EXECUTIVE OFFICER.  The Company and the Chief Executive Officer, Steven M. 
Willens, represent and warrant to and agree with each of the Underwriters 
that:

    Registration Statement is in effect, and no proceedings for such purpose 
    are pending before or threatened by the Commission.

     (b)  (i)  The Registration Statement, when it became 
    effective, did not contain and, as amended or supplemented, if

    fact or omit to state a material fact required to be stated therein 
    or necessary to make the statements therein not misleading, (ii)

    does not contain and, as amended or supplemented, if applicable,

    misleading, except that the representations and warranties set 
    forth in this paragraph 1(b) do not apply to statements or

    adverse effect on the Company and its subsidiaries, taken as a 
    whole.

    incorporated, is validly existing as a corporation in good standing

    effect on the Company and its subsidiaries, taken as a whole; all

    conduct their respective businesses, and neither the Company nor

    to the revocation or modification of any such certificate, 
    authorization or permit which, singly or in the aggregate, if the 
    subject of an unfavorable decision, ruling or finding, would result 
    in a material adverse change in the condition, financial or 
    otherwise, or in the earnings, business or operations of the 
    Company and its subsidiaries, taken as a whole, except as described 
    in or contemplated by the Prospectus.

         (j)  The execution and delivery by the Company of, and the performance
    by the Company of its obligations under, this Agreement will not contravene
    any provision of applicable law or the certificate of incorporation or
    by-laws of the Company or any agreement or other instrument binding upon
    the Company or any of its subsidiaries that is material to the Company and
    its subsidiaries, taken as a whole, or any judgment, order or decree of any
    governmental body, agency or court having jurisdiction over the Company or
    any subsidiary, and no consent, approval, authorization or order of, or
    qualification with, any governmental body or agency is required for the
    performance by the Company of its obligations under this Agreement, except
    such as may be required by the securities or Blue Sky laws of the various
    states in connection with the offer and sale of the Shares.

    condition, financial or otherwise, or in the earnings, business or
    operations of the Company and its subsidiaries, taken as a whole, from that

<PAGE>

         (l)  There are no legal or governmental proceedings pending or

    subject that are required to be described in the Registration Statement or
    the Prospectus and are not so described or any statutes, regulations,
    contracts or other documents that are required to be described in the

    under applicable occupational safety and health and environmental laws to
    conduct their respective businesses and (iii) are in compliance with all
    terms and conditions of any such permit, license or approval, except where
    such noncompliance with, failure to receive required permits, licenses or
    other approvals or failure to comply with the terms and conditions of such
    permits, licenses or approvals would not, singly or in the aggregate, have
    a material adverse effect on the Company and its subsidiaries, taken as a
    whole, except as described in or contemplated by the Prospectus.

                                      6

<PAGE>

         (p)  There are no costs or liabilities associated with occupational
    safety and health and environmental laws (including, without limitation,
    any capital or operating expenditures required for clean-up, closure of
    properties or compliance with occupational safety and health and
    environmental laws or any permit, license or approval, any related
    constraints on operating activities and any potential liabilities to third
    parties) which would, singly or in the aggregate, have a material adverse
    effect on the Company and its subsidiaries, taken as a whole.

         (q)  There are no contracts, agreements or understandings between the
    Company and any person granting such person the right to require the
    Company to file a registration statement under the Securities Act with
    respect to any securities of the Company or to require the Company to
    include such securities with the Shares registered pursuant to the
    Registration Statement.  

         (r)  The Company and its subsidiaries have good and marketable title
    in fee simple to all real property and good and marketable title to all
    personal property owned by them which is material to the business of the
    Company and its subsidiaries, in each case free and clear of all liens,
    encumbrances and defects except such as are described in the Prospectus or
    such as do not materially affect the value of such property and do not
    interfere with the use made and proposed to be made of such property by the
    Company and its subsidiaries; and any real property and buildings held
    under lease by the Company and its subsidiaries are held by them under
    valid, subsisting and enforceable leases with such exceptions as are not
    material and do not interfere with the use made and proposed to be made of
    such property and buildings by the Company and its subsidiaries, in each
    case except as described in or contemplated by the Prospectus.

         (s)  The Company and its subsidiaries own or possess, or can acquire

    systems or procedures), trademarks, service marks with trade

    names currently employed by them in connection with the business 
    now operated by them, and neither the Company nor any of its 
    subsidiaries has received any notice of infringement of or conflict 
    with asserted rights of others with respect to any of the foregoing 
    which, singly or in the aggregate, if the subject of an unfavorable 
    decision, ruling or finding, would result in any material adverse 
    change in the condition, financial or otherwise, or in the 
    earnings, business or operations of the Company and its 
    subsidiaries, taken as a whole.

         (t)  No material labor dispute with the employees of the Company or
    any of its subsidiaries exists, except as described in or contemplated by
    the Prospectus, or, to the knowledge of the Company, is imminent; and the

    disturbance by the employees of any of its principal suppliers,
    manufacturers or contractors that could result in any material adverse
    change in the condition, financial or otherwise, or in the earnings,
    business or operations of the Company and its subsidiaries, taken as a
    whole.

         (u)  The Company and each of its subsidiaries are insured by insurers
    of recognized financial responsibility against such losses and risks and in
    such amounts as are prudent and customary in the businesses in which they
    are engaged; neither the Company nor any such subsidiary has been refused
    any insurance coverage sought or applied for; and neither the Company nor
    any such subsidiary has any reason to believe that it will not be able to
    renew its existing insurance coverage as and when such coverage expires or
    to obtain similar coverage from similar insurers as may be necessary to
    continue its business at a cost that would not materially and adversely
    affect the condition, financial or otherwise, or the earnings, business or

and not jointly, to purchase from such Seller at $______ a share (the "Purchase
Price") the number of Firm Shares (subject to such adjustments to eliminate

exercisable or exchangeable for Common Stock or (ii) enter into any 
swap or other arrangement that transfers to another, in whole or in 
part, any of the economic consequences of ownership of the Common 
Stock, whether any such transaction described in clause (i) or (ii) 
above is to be settled by delivery of Common Stock or such other 
securities, in cash or otherwise.  The foregoing sentence shall not 
apply to (A) the Shares to be sold hereunder or (B) the issuance by 
the Company of shares of Common Stock upon the exercise of an

that the Registration Statement shall have become effective not 
later than 5:00 p.m. (New York City time) on the date hereof.

          The several obligations of the Underwriters are subject

               (i)  there shall not have occurred any downgrading, 
          nor shall any notice have been given of any intended or potential 
          downgrading or of any review for a possible change that does not 
          indicate the direction of the possible change, in the rating 
          accorded any of the Company's securities by any "nationally

              (ii)  there shall not have occurred any change, or any 
          development involving a prospective change, in the condition,

          set forth in the Prospectus (exclusive of any amendments or 
          supplements thereto subsequent to the date of this Agreement) that, 
          in your judgment, is material and adverse and that makes it, in 
          your judgment, impracticable to market the Shares on the terms and 
          in the manner contemplated in the Prospectus.

          (b)  The Underwriters shall have received on the Closing Date a

          order to make the statements therein, in the light of the 
          circumstances under which they were made, not misleading.

          has no reason to believe that (except for financial statements and 
          schedules and other financial and statistical data as to which such 
          counsel need not express any belief) the Registration Statement and 
          the prospectus included therein at the time the Registration 
          Statement became effective contained any untrue statement of a 
          material fact or omitted to state a material fact required to be 
          stated therein or necessary to make the statements therein not 
          misleading and (C) has no reason to believe that (except for 
          financial statements and schedules and other financial

                                      20

<PAGE>

          and statistical data as to which such counsel need not express any 
          belief) the Prospectus contains any untrue statement of a material 
          fact or omits to state a material fact necessary in order to make 
          the statements therein, in the light of the circumstances under 
          which they were made, not misleading.

          (e)  The Underwriters shall have received on the Closing Date an
     opinion of Brobeck, Phleger & Harrison LLP, counsel for the Underwriters,
     dated the Closing Date, covering the matters referred to in subparagraphs
     (vi), (vii), (ix) (but only as to the statements in the Prospectus under
     "Description of Capital Stock" and "Underwriters") and (xiii) of paragraph
     (c) above.

          With respect to subparagraph (xiii) of paragraph (c) above, 
     Wilson, Sonsini, Goodrich & Rosati and Brobeck, Phleger & Harrison 
     LLP and with respect to subparagraph (vi) of paragraph (d) above, 
     Wilson, Sonsini, Goodrich & Rosati, may state that their opinion 
     and belief are based upon their participation in the preparation of 
     the Registration Statement and Prospectus and any amendments or 
     supplements thereto and review and discussion of the contents 
     thereof, but are without independent check or verification, except 
     as specified.  With respect to paragraph (d) above, Wilson, 
     Sonsini, Goodrich & Rosati may rely upon an opinion or opinions of 
     counsel for any Selling Shareholders and, with respect to factual 
     matters and to the extent such counsel deems appropriate, upon the 
     representations of each Selling Shareholder contained herein and in 
     the Custody Agreement and Power of Attorney of such Selling 
     Shareholder and in other documents and instruments; PROVIDED that 
     (A) each such counsel for the Selling Shareholders is satisfactory 
     to your counsel, (B) a copy of each opinion so relied upon is 
     delivered to you and is in form and substance satisfactory to your 
     counsel, (C) copies of such Custody Agreements and Powers of 
     Attorney and of any such other documents and instruments shall be 
     delivered to you and shall be in form and substance satisfactory to 
     your counsel and (D) Wilson, Sonsini, Goodrich & Rosati shall state 
     in their opinion that they are justified in relying on each such 
     other opinion.

                                      21

<PAGE>

          The opinions of Wilson, Sonsini, Goodrich & Rosati described in
     paragraphs (c) and (d) above (and any opinions of counsel for any Selling
     Shareholder referred to in the immediately preceding paragraph) shall be
     rendered to the Underwriters at the request of the Company or one or more
     of the Selling Shareholders, as the case may be, and shall so state
     therein.

          (f)  The Underwriters shall have received, on each of the date 
     hereof and the Closing Date, a letter dated the date hereof or the 
     Closing Date, as the case may be, in form and substance 
     satisfactory to the Underwriters, from KPMG Peat Marwick LLP 
     independent public accountants, containing statements and 
     information of the type ordinarily included in accountants' 
     "comfort letters" to underwriters with respect to the financial 
     statements and certain financial information contained in the 
     Registration Statement and the Prospectus; PROVIDED that the letter 
     delivered on the Closing Date shall use a "cut-off date" not 
     earlier than the date hereof.

          (g)  The "lock-up" agreements, each substantially in the form 
     of Exhibit A hereto, between you and certain shareholders, officers 
     and directors of the Company relating to sales and certain other 
     dispositions of shares of Common Stock or certain other securities, 
     delivered to you on or before the date hereof, shall be in full 
     force and effect on the Closing Date.

          The several obligations of the Underwriters to purchase 
Additional Shares hereunder are subject to the delivery to you on 
the Option Closing Date of such documents as you may reasonably 
request with respect to the good standing of the Company, the due 
authorization and issuance of the Additional Shares and other 
matters related to the issuance of the Additional Shares.

          7.   COVENANTS OF THE COMPANY.  In further consideration 
of the agreements of the Underwriters herein contained, the Company 
covenants with each Underwriter as follows:

          (a)  To furnish to you, without charge, four

                                      22

<PAGE>

     signed copies of the Registration Statement (including exhibits 
     thereto) and for delivery to each other Underwriter a conformed 
     copy of the Registration Statement (without exhibits thereto) and 
     to furnish to you in New York City, without charge, prior to 10:00 
     A.M. New York City time on the business day next succeeding the 
     date of this Agreement and during the period mentioned in paragraph 
     (c) below, as many copies of the Prospectus and any supplements and 
     amendments thereto or to the Registration Statement as you may 
     reasonably request.

          (b)  Before amending or supplementing the Registration 
     Statement or the Prospectus, to furnish to you a copy of each such 
     proposed amendment or supplement and not to file any such proposed 
     amendment or supplement to which you reasonably object, and to file 
     with the Commission within the applicable period specified in Rule 
     424(b) under the Securities Act any prospectus required to be filed 
     pursuant to such Rule.
     
          (c)  If, during such period after the first date of the public 
     offering of the Shares as in the opinion of counsel for the 
     Underwriters the Prospectus is required by law to be delivered in 
     connection with sales by an Underwriter or dealer, any event shall 
     occur or condition exist as a result of which it is necessary to 
     amend or supplement the Prospectus in order to make the statements 
     therein, in the light of the circumstances when the Prospectus is 
     delivered to a purchaser, not misleading, or if, in the opinion of 
     counsel for the Underwriters, it is necessary to amend or 
     supplement the Prospectus to comply with applicable law, forthwith 
     to prepare, file with the Commission and furnish, at its own 
     expense, to the Underwriters and to the dealers (whose names and 
     addresses you will furnish to the Company) to which Shares may have 
     been sold by you on behalf of the Underwriters and to any other 
     dealers upon request, either amendments or supplements to the 
     Prospectus so that the statements in the Prospectus as so amended 
     or supplemented will not, in the light of the circumstances when 
     the Prospectus is delivered to a purchaser, be misleading or so 
     that the Prospectus, as amended or supplemented, will comply with 
     law.

                                      23

<PAGE>

          (d)  To endeavor to qualify the Shares for offer and sale under the
     securities or Blue Sky laws of such jurisdictions as you shall reasonably
     request.

          (e)  To make generally available to the Company's security 
     holders and to you as soon as practicable an earning statement 
     covering the twelve-month period ending ________, 1998(3) that 
     satisfies the provisions of Section 11(a) of the Securities Act and 
     the rules and regulations of the Commission thereunder.

          (f)  That in connection with the Directed Share Program, the 
     Company will ensure that the Directed Shares will be restricted to 
     the extent required by the National Association of Securities 
     Dealers, Inc. (the "NASD") or the NASD rules from sale, transfer, 
     assignment, pledge or hypothecation for a period of three months 
     following the date of the effectiveness of the Registration 
     Statement.  You will notify the Company as to which Participants 
     will need to be so restricted.  The Company will direct the 
     transfer agent to place stop transfer restrictions upon such 
     securities for such period of time.
     
          (g)  To pay all fees and disbursements of counsel incurred by 
     the Underwriters in connection with the Directed Share Program and 
     stamp duties, similar taxes or duties or other taxes, if any, 
     incurred by the Underwriters in connection with the Directed Share 
     Program.

          Furthermore, the Company covenants with you that the 
Company will comply with all applicable securities and other 
applicable laws, rules and regulations in each foreign jurisdiction 
in which the Directed Shares are offered in connection with the 
Directed Share Program.

          8.   EXPENSES.  Whether or not the transactions 
contemplated in this Agreement are consummated or this Agreement is 
terminated, the Sellers agree to pay or cause to be paid all

the Company and any such consultants, and the cost of any aircraft chartered 
in connection with the road show, and (ix) all other costs and expenses 
incident to the performance of the obligations of the Company hereunder for 
which provision is not otherwise made in this Section.  It is understood, 
however, that except as provided in

                                      25

<PAGE>

this Section, Section 9 entitled "Indemnity and Contribution", and the last 
paragraph of Section 11 below, the Underwriters will pay all of their costs 
and expenses, including fees and disbursements of their counsel, stock 
transfer taxes payable on resale of any of the Shares by them and any 
advertising expenses connected with any offers they may make.

          The provisions of this Section shall not supersede or otherwise 
affect any agreement that the Sellers may otherwise have for the allocation 
of such expenses among themselves.

          9.   INDEMNITY AND CONTRIBUTION.  (a)  The Company and, with 
respect to Sections (i), (ii) and (iii) of this paragraph 9(a), Steve 
Willens, jointly and severally, agree to indemnify and hold harmless each 
Underwriter and each person, if any, who controls any Underwriter within the 
meaning of either Section 15 of the Securities Act or Section 20 of the 
Securities Exchange Act of 1934, as amended (the "Exchange Act"), from and 
against any and all losses, claims, damages and liabilities (including, 
without limitation, any legal or other expenses reasonably incurred in 
connection with defending or investigating any such action or claim) (i) 
caused by any untrue statement or alleged untrue statement of a material fact 
contained in the Registration Statement or any amendment thereof, any 
preliminary prospectus or the Prospectus (as amended or supplemented if the 
Company shall have furnished any amendments or supplements thereto); (ii) 
caused by 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, except insofar as such losses, claims, damages or liabilities are 
caused by any such untrue statement or omission or alleged untrue statement 
or omission based upon information relating to any Underwriter furnished to 
the Company in writing by such Underwriter through you expressly for use 
therein; (iii) caused by any untrue statement or alleged untrue statement of 
a material fact contained in the prospectus wrapper material prepared by or 
with the consent of the Company for distribution in foreign jurisdictions in 
connection with the Directed Share Program attached to the Prospectus or any 
preliminary prospectus, or caused by any omission or alleged omission to 
state therein a material fact required to be stated therein or necessary to 
make the statement therein, when considered in conjunction with the 
Prospectus or any applicable preliminary prospectus, not misleading; (iv) 
caused by the

                                      26

<PAGE>

failure of any Participant to pay for and accept delivery of the shares in 
the Directed Share Program which, immediately following the effectiveness of 
the Registration Statement, were subject to a properly confirmed agreement to 
purchase; or (v) related to, arising out of, or in connection with the 
Directed Share Program, provided that, the Company shall not be responsible 
under this subparagraph (v) for any losses, claim, damages or liabilities (or 
expenses relating thereto) that are finally judicially determined to have 
resulted from your bad faith or gross negligence.

          (b)  Each Selling Shareholder agrees, severally and not jointly, to 
indemnify and hold harmless the Company, its directors, its officers who sign 
the Registration Statement and each person, if any, who controls the Company 
within the meaning of either Section 15 of the Securities Act or Section 20 
of the Exchange Act, from and against any and all losses, claims, damages and 
liabilities (including, without limitation, any legal or other expenses 
reasonably incurred in connection with defending or investigating any such 
action or claim) caused by any untrue statement or alleged untrue statement 
of a material fact contained in the Registration Statement or any amendment 
thereof, any preliminary prospectus or the Prospectus (as amended or 
supplemented if the Company shall have furnished any amendments or 
supplements thereto), or caused by 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, but only with reference to information 
relating to such Selling Shareholder furnished in writing by or on behalf of 
such Selling Shareholder expressly for use in the Registration Statement, any 
preliminary prospectus, the Prospectus or any amendments or supplements 
thereto.

          (c)  Each Underwriter agrees, severally and not jointly, to 
indemnify and hold harmless the Company, the Selling Shareholders, the 
directors of the Company, the officers of the Company who sign the 
Registration Statement and each person, if any, who controls the Company or 
any Selling Shareholder within the meaning of either Section 15 of the 
Securities Act or Section 20 of the Exchange Act from and against any and all 
losses, claims, damages and liabilities (including, without limitation, any 
legal or other expenses reasonably incurred in connection

                                      27

<PAGE>

with defending or investigating any such action or claim) caused by any 
untrue statement or alleged untrue statement of a material fact contained in 
the Registration Statement or any amendment thereof, any preliminary 
prospectus or the Prospectus (as amended or supplemented if the Company shall 
have furnished any amendments or supplements thereto), or caused by 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, 
but only with reference to information relating to such Underwriter furnished 
to the Company in writing by such Underwriter through you expressly for use 
in the Registration Statement, any preliminary prospectus, the Prospectus or 
any amendments or supplements thereto.

          (d)  In case any proceeding (including any governmental 
investigation) shall be instituted involving any person in respect of which 
indemnity may be sought pursuant to paragraph (a), (b) or (c) of this Section 
9, such person (the "indemnified party") shall promptly notify the person 
against whom such indemnity may be sought (the "indemnifying party") in 
writing and the indemnifying party, upon request of the indemnified party, 
shall retain counsel reasonably satisfactory to the indemnified party to 
represent the indemnified party and any others the indemnifying party may 
designate in such proceeding and shall pay the fees and disbursements of such 
counsel related to such proceeding. In any such proceeding, any indemnified 
party shall have the right to retain its own counsel, but the fees and 
expenses of such counsel shall be at the expense of such indemnified party 
unless (i) the indemnifying party and the indemnified party shall have 
mutually agreed to the retention of such counsel or (ii) the named parties to 
any such proceeding (including any impleaded parties) include both the 
indemnifying party and the indemnified party and representation of both 
parties by the same counsel would be inappropriate due to actual or potential 
differing interests between them.  It is understood that the indemnifying 
party shall not, in respect of the legal expenses of any indemnified party in 
connection with any proceeding or related proceedings in the same 
jurisdiction, be liable for (i) the fees and expenses of more than one 
separate firm (in addition to any local counsel) for all Underwriters and all 
persons, if any, who control any Underwriter within the meaning of either 
Section 15 of the Securities Act or Section 20

                                      28

<PAGE>

of the Exchange Act, (ii) the fees and expenses of more than one separate 
firm (in addition to any local counsel) for the Company, its directors, its 
officers who sign the Registration Statement and each person, if any, who 
controls the Company within the meaning of either such Section and (iii) the 
fees and expenses of more than one separate firm (in addition to any local 
counsel) for all Selling Shareholders and all persons, if any, who control 
any Selling Shareholder within the meaning of either such Section, and that 
all such fees and expenses shall be reimbursed as they are incurred.  In the 
case of any such separate firm for the Underwriters and such control persons 
of any Underwriters, such firm shall be designated in writing by Morgan 
Stanley & Co. Incorporated.  In the case of any such separate firm for the 
Company, and such directors, officers and control persons of the Company, 
such firm shall be designated in writing by the Company.  In the case of any 
such separate firm for the Selling Shareholders and such control persons of 
any Selling Shareholders, such firm shall be designated in writing by the 
persons named as attorneys-in-fact for the Selling Shareholders under the 
Powers of Attorney. The indemnifying party shall not be liable for any 
settlement of any proceeding effected without its written consent, but if 
settled with such consent or if there be a final judgment for the plaintiff, 
the indemnifying party agrees to indemnify the indemnified party from and 
against any loss or liability by reason of such settlement or judgment.  
Notwithstanding the foregoing sentence, if at any time an indemnified party 
shall have requested an indemnifying party to reimburse the indemnified party 
for fees and expenses of counsel as contemplated by the second and third 
sentences of this paragraph, the indemnifying party agrees that it shall be 
liable for any settlement of any proceeding effected without its written 
consent if (i) such settlement is entered into more than 30 days after 
receipt by such indemnifying party of the aforesaid request and (ii) such 
indemnifying party shall not have reimbursed the indemnified party in 
accordance with such request prior to the date of such settlement.  No 
indemnifying party shall, without the prior written consent of the 
indemnified party, effect any settlement of any pending or threatened 
proceeding in respect of which any indemnified party is or could have been a 
party and indemnity could have been sought hereunder by such indemnified 
party, unless such settlement includes an unconditional release of such 
indemnified party from all liability on claims that are

                                      29

<PAGE>

the subject matter of such proceeding.  Notwithstanding anything contained 
herein to the contrary, if indemnity may be sought pursuant to paragraph (a) 
of this Section 9 with regard to the Directed Share Program, then in addition 
to such separate firm for the indemnified parties, the indemnifying party 
shall be liable for the reasonable fees and expenses of not more than one 
separate firm (in addition to any local counsel) for Morgan Stanley & Co. 
Incorporated for the defense of any losses, claims, damages and liabilities 
arising out of the Directed Share Program, and all persons, if any, who 
control Morgan Stanley & Co. Incorporated within the meaning of either 
Section 15 of the Act or Section 20 of the Exchange Act.

          (e)  To the extent the indemnification provided for in paragraph 
(a), (b) or (c) of this Section 9 is unavailable to an indemnified party or 
insufficient in respect of any losses, claims, damages or liabilities 
referred to therein, then each indemnifying party under such paragraph, in 
lieu of indemnifying such indemnified party thereunder, shall contribute to 
the amount paid or payable by such indemnified party as a result of such 
losses, claims, damages or liabilities (i) in such proportion as is 
appropriate to reflect the relative benefits received by the indemnifying 
party or parties on the one hand and the indemnified party or parties on the 
other hand from the offering of the Shares or (ii) if the allocation provided 
by clause (i) above is not permitted by applicable law, in such proportion as 
is appropriate to reflect not only the relative benefits referred to in 
clause (i) above but also the relative fault of the indemnifying party or 
parties on the one hand and of the indemnified party or parties on the other 
hand in connection with the statements or omissions that resulted in such 
losses, claims, damages or liabilities, as well as any other relevant 
equitable considerations.  The relative benefits received by the Sellers on 
the one hand and the Underwriters on the other hand in connection with the 
offering of the Shares shall be deemed to be in the same respective 
proportions as the net proceeds from the offering of the Shares (before 
deducting expenses) received by each Seller and the total underwriting 
discounts and commissions received by the Underwriters, in each case as set 
forth in the table on the cover of the Prospectus, bear to the aggregate 
Public Offering Price of the Shares.  The relative fault of the Sellers on 
the one hand and the Underwriters on the other hand shall be

                                      30

<PAGE>


determined by reference to, among other things, whether the untrue or alleged 
untrue statement of a material fact or the omission or alleged omission to 
state a material fact relates to information supplied by the Sellers or by 
the Underwriters and the parties' relative intent, knowledge, access to 
information and opportunity to correct or prevent such statement or omission. 
The Underwriters' respective obligations to contribute pursuant to this 
Section 9 are several in proportion to the respective number of Shares they 
have purchased hereunder, and not joint.

          (f)  The Sellers and the Underwriters agree that it would not be 
just or equitable if contribution pursuant to this Section 9 were determined 
by PRO RATA allocation (even if the Underwriters were treated as one entity 
for such purpose) or by any other method of allocation that does not take 
account of the equitable considerations referred to in paragraph (e) of this 
Section 9.  The amount paid or payable by an indemnified party as a result of 
the losses, claims, damages and liabilities referred to in the immediately 
preceding paragraph shall be deemed to include, subject to the limitations 
set forth above, any legal or other expenses reasonably incurred by such 
indemnified party in connection with investigating or defending any such 
action or claim. Notwithstanding the provisions of this Section 9, no 
Underwriter shall be required to contribute any amount in excess of the 
amount by which the total price at which the Shares underwritten by it and 
distributed to the public were offered to the public exceeds the amount of 
any damages that such Underwriter has otherwise been required to pay by 
reason of such untrue or alleged untrue statement or omission or alleged 
omission.  No person guilty of fraudulent misrepresentation (within the 
meaning of Section 11(f) of the Securities Act) shall be entitled to 
contribution from any person who was not guilty of such fraudulent 
misrepresentation.  The remedies provided for in this Section 9 are not 
exclusive and shall not limit any rights or remedies which may otherwise be 
available to any indemnified party at law or in equity.

          (g)  The indemnity and contribution provisions contained in this 
Section 9 and the representations, warranties and other statements of the 
Company and the Selling Shareholders contained in this Agreement shall remain 
operative and in full force and effect regardless of (i) any termination of 
this

                                      31

<PAGE>

Agreement, (ii) any investigation made by or on behalf of any Underwriter or 
any person controlling any Underwriter, any Selling Shareholder or any person 
controlling any Selling Shareholder, or the Company, its officers or 
directors or any person controlling the Company and (iii) acceptance of and 
payment for any of the Shares.

          (h)  Notwithstanding any other provision of this Agreement, the 
liability of each Selling Shareholder under the representations, warranties 
and agrements contained in this Agrement and under the indemnity and other 
agrements contained in the provisions of this Section 9 shall be limited to 
an amount equal to the initial public offering price of the Selling 
Shareholder Shares sold by such Selling Shareholder to the Underwriters minus 
the amount of the underwriting discount paid thereon to the Underwriters by 
such Selling Shareholder. The Company and such Selling Shareholders may 
agree, as among themselves and without limiting the rights of the 
Underwriters under this Agrement, as to the respective amounts of such 
liability for which they each shall be responsible.

          10.  TERMINATION.  This Agreement shall be subject to termination 
by notice given by you to the Company, if (a) after the execution and 
delivery of this Agreement and prior to the Closing Date (i) trading 
generally shall have been suspended or materially limited on or by, as the 
case may be, any of the New York Stock Exchange, the American Stock Exchange, 
the National Association of Securities Dealers, Inc., the Chicago Board of 
Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of 
Trade, (ii) trading of any securities of the Company shall have been 
suspended on any exchange or in any over-the-counter market, (iii) a general 
moratorium on commercial banking activities in New York shall have been 
declared by either Federal or New York State authorities or (iv) there shall 
have occurred any outbreak or escalation of hostilities or any change in 
financial markets or any calamity or crisis that, in your judgment, is 
material and adverse and (b) in the case of any of the events specified in 
clauses (a)(i) through (iv), such event, singly or together with any other 
such event, makes it, in your judgment, impracticable to market the Shares on 
the terms and in the manner contemplated in the Prospectus.

          11.  EFFECTIVENESS; DEFAULTING UNDERWRITERS.  This Agreement shall 
become effective upon the execution and delivery hereof by the parties hereto.

          If, on the Closing Date or the Option Closing Date, as the case may 
be, any one or more of the Underwriters shall fail or refuse to purchase 
Shares that it has or they have agreed to purchase hereunder on such date, 
and the aggregate number of Shares which such defaulting Underwriter or 
Underwriters agreed but failed or refused to purchase is not more than 
one-tenth of the aggregate number of the Shares to be purchased on such date, 
the other Underwriters shall be obligated severally in the proportions that 
the number of Firm Shares set forth opposite their respective names in 
Schedule II bears to the aggregate

                                      32

<PAGE>


number of Firm Shares set forth opposite the names of all such non-defaulting 
Underwriters, or in such other proportions as you may specify, to purchase 
the Shares which such defaulting Underwriter or Underwriters agreed but 
failed or refused to purchase on such date; PROVIDED that in no event shall 
the number of Shares that any Underwriter has agreed to purchase pursuant to 
this Agreement be increased pursuant to this Section 11 by an amount in 
excess of one-ninth of such number of Shares without the written consent of 
such Underwriter.  If, on the Closing Date, any Underwriter or Underwriters 
shall fail or refuse to purchase Firm Shares and the aggregate number of Firm 
Shares with respect to which such default occurs is more than one-tenth of 
the aggregate number of Firm Shares to be purchased, and arrangements 
satisfactory to you, the Company and the Selling Shareholders for the 
purchase of such Firm Shares are not made within 36 hours after such default, 
this Agreement shall terminate without liability on the part of any 
non-defaulting Underwriter, the Company or the Selling Shareholders.  In any 
such case either you or the relevant Sellers shall have the right to postpone 
the Closing Date, but in no event for longer than seven days, in order that 
the required changes, if any, in the Registration Statement and in the 
Prospectus or in any other documents or arrangements may be effected.  If, on 
the Option Closing Date, any Underwriter or Underwriters shall fail or refuse 
to purchase Additional Shares and the aggregate number of Additional Shares 
with respect to which such default occurs is more than one-tenth of the 
aggregate number of Additional Shares to be purchased, the non-defaulting 
Underwriters shall have the option to (i) terminate their obligation 
hereunder to purchase Additional Shares or (ii) purchase not less than the 
number of Additional Shares that such non-defaulting Underwriters would have 
been obligated to purchase in the absence of such default.  Any action taken 
under this paragraph shall not relieve any defaulting Underwriter from 
liability in respect of any default of such Underwriter under this Agreement.

          If this Agreement shall be terminated by the Underwriters, or any 
of them, because of any failure or refusal on the part of any Seller to 
comply with the terms or to fulfill any of the conditions of this Agreement, 
or if for any reason any Seller shall be unable to perform its obligations 
under this Agreement, the Sellers will reimburse the Underwriters or such

                                      33

Underwriters as have so terminated this Agreement with respect to themselves, 
severally, for all out-of-pocket expenses (including the fees and 
disbursements of their counsel) reasonably incurred by such Underwriters in 
connection with this Agreement or the offering contemplated hereunder.

          12.  COUNTERPARTS.  This Agreement may be signed in two or more 
counterparts, each of which shall be an original, with the same effect as if 
the signatures thereto and hereto were upon the same instrument.

          13.  APPLICABLE LAW.  This Agreement shall be governed by and 
construed in accordance with the internal laws of the State of New York.

          14.  HEADINGS.  The headings of the sections of this Agreement have 
been inserted for convenience of reference only and shall not be deemed a 
part of this Agreement.

Dear Sirs:

     The undersigned understands that Morgan Stanley & Co. Incorporated 
("Morgan Stanley"), as Representative of the several Underwriters, proposes 
to enter into an Underwriting Agreement (the "Underwriting Agreement") with 
Livingston Enterprises, Inc., a California corporation (the "Company") 
providing for the public offering (the "Public Offering") by the several 
Underwriters, including Morgan Stanley (the "Underwriters"), of 
______________ shares (the "Shares") of the Common Stock, no par value, of 
the Company (the "Common Stock").

     To induce the Underwriters that may participate in the Public Offering 
to continue their efforts in connection with the Public Offering, the 
undersigned hereby agrees that, without the prior written consent of Morgan 
Stanley on behalf of the Underwriters, it will not, during the period 
commencing on the date hereof and ending 180 days after the date of the final 
prospectus relating to the Public Offering (the "Prospectus"), (1) offer, 
pledge, sell, contract to sell, sell any option or contract to purchase, 
purchase any option or contract to sell, grant any option, right or warrant 
to purchase, or otherwise transfer or dispose of, directly or indirectly, any 
shares of Common Stock or any securities convertible into or exercisable or 
exchangeable for Common Stock (provided that such shares or securities are 
either now owned by the undersigned or are hereafter acquired prior to or in 
connection with the Public Offering), or (2) enter into any swap or other 
arrangement that transfers to another, in whole or in part, any of the 
economic consequences of ownership of such shares of Common Stock, whether 
any such transaction described in clause (1) or (2) above is to be settled by 
delivery of Common Stock or such other securities, in cash or otherwise.  The 
foregoing sentence shall not apply to the sale of any Shares to the 
Underwriters pursuant to the Underwriting Agreement.  In addition, the 
undersigned agrees that, without the prior written consent of Morgan Stanley 
on behalf of the Underwriters, it will not, during the period commencing on 
the date hereof and ending 180 days after the date of the Prospectus, make 
any demand for or exercise any right with respect to, the registration of any 
shares of Common Stock or any security convertible into or exercisable or 
exchangeable for Common Stock.

     Whether or not the Public Offering actually occurs depends on a number 
of factors, including market conditions.  Any Public Offering will only be 
made pursuant to an Underwriting Agreement, the terms of which are subject to 
agreement between the Company and the Underwriters.

                                        Very truly yours,

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

                                 LIVINGSTON ENTERPRISES, INC.


Jerrold Livingston and Steven M. Willens certify that:

1.  They are the duly elected and acting President and Chief Financial Officer,
    respectively of Livingston Enterprises, Inc., a California corporation.

2.  The Articles of Incorporation of this corporation are amended and restated
    to read in full as follows:


                                      ARTICLE I

                           The name of this corporation is:

                             Livingston Enterprises, Inc.


                                      ARTICLE II

    The purpose of this corporation is to engage in any lawful act or activity
    for which a corporation may be organized under the General Corporation Law
    of California other than the banking business, the trust company business or
    the practice of a profession permitted to be incorporated by the California
    Corporations Code.


                                      ARTICLE III


     (a) The corporation is authorized to issue two classes of shares designated
     "Preferred Stock" and "Common Stock," respectively. The number of shares of
     Preferred Stock authorized to be issued is five million (5,000,000) and the
     number of shares of Common Stock authorized to be issued is ten million 
     (10,000,000).

     (b) The Preferred Stock may be divided into such number of series as the 
     Board of Directors may determine. The Board of Directors is authorized to 
     determine and alter the rights, preferences, privileges, and restrictions 
     granted to and imposed upon any wholly unissued series of Preferred Stock,
     and to fix the number of shares of any series of Preferred Stock and the 
     designation of any such series of Preferred Stock. The Board of Directors,
     within the limits and restrictions stated in any resolution or resolutions
     of the Board of Directors originally fixing the number of shares
     constituting any series, may increase or decrease (but not below the number
     of shares of such series then outstanding) the number of shares of any 
     series subsequent to the issue of shares of that series.


<PAGE>


                                      ARTICLE IV


     (a) The liability of directors of the corporation for monetary damages 
     shall be eliminated to the fullest extent permissible under California law.

     (b) The corporation is authorized to provide indemnification of agents (as
     defined in Section 317 of the California Corporations Code) through 
     bylaw provisions, agreements with agents, vote of shareholders or 
     disinterested directors, or otherwise, to the fullest extent permissible
     under California law.

     (c) Any amendment, repeal or modification of any provision of this 
     Article IV shall not adversely affect any right or protection of an agent
     of this corporation existing at the time of such amendment, repeal or 
     modification.

3.   The foregoing Amendment and Restatement of Article of Incorporation has 
     been duly approved by the Board of Directors of the corporation.

4.   The foregoing Amendment and Restatement of Articles of Incorporation has
     been duly approved by the required vote of shareholders in accordance with
     Section 902 of the California Corporations Code. The total number of 
     outstanding shares of the corporation is 675,000 (Common Stock). The number
     of shares voting in favor of the Amendment and Restatement exceeded the
     vote required, such vote being unanimous.

     We further declare under penalty of perjury under the laws of the State of
     California that the matters set forth in this certificate are true and
     correct of our own knowledge.

     1.1  PRINCIPAL OFFICE

     The Board of Directors shall fix the location of the principal executive
office of the corporation at any place within or outside the State of
California.  If the principal executive office is located outside California and
the corporation has one or more business offices in California, then the Board
of Directors shall fix and designate a principal business office in California.

     1.2  OTHER OFFICES

     The Board of Directors may at any time establish branch or subordinate
offices at any place or places.

II

                            MEETINGS OF SHAREHOLDERS

     2.1  PLACE OF MEETINGS

     Meetings of shareholders shall be held at any place within or outside the
State of California designated by the Board of Directors.  In the absence of any
such designation, shareholders' meetings shall be held at the principal
executive office of the corporation or at any place consented to in writing by
all persons entitled to vote at such meeting, given before or after the meeting
and filed with the Secretary of the corporation.

     2.2  ANNUAL MEETING

     An annual meeting of shareholders shall be held each year on a date and at
a time designated by the Board of Directors.  At that meeting, directors shall
be elected.  Any other proper business may be transacted at the annual meeting
of shareholders.

     2.3  SPECIAL MEETINGS

     Special meetings of the shareholders may be called at any time, subject to
the provisions of Sections 2.4 and 2.5 of these Bylaws, by the Board of
Directors, the Chairman of the Board, the President or the holders of shares
entitled to cast not less than ten percent (10%) of the votes at that meeting.

     If a special meeting is called by anyone other than the Board of Directors
or the President or the Chairman of the Board, then the request shall be in
writing, specifying the time of such meeting and the general nature of the
business proposed to be transacted, and shall be delivered personally or sent by
registered mail or by other written communication to the Chairman of the Board,
the President, any Vice President or the Secretary of the corporation.  The
officer receiving the request forthwith shall cause notice to be given to the
shareholders entitled to vote, in accordance with the provisions of Sections 2.4
and 2.5 of these Bylaws, that a meeting will be held at the time requested by
the person or persons calling the meeting, so long as that time is not less than

<PAGE>

thirty-five (35) nor more than sixty (60) days after the receipt of the request.
If the notice is not given within twenty (20) days after receipt of the request,
then the person or persons requesting the meeting may give the notice.  Nothing
contained in this paragraph of this Section 2.3 shall be construed as limiting,
fixing or affecting the time when a meeting of shareholders called by action of
the Board of Directors may be held.

     2.4  NOTICE OF SHAREHOLDERS' MEETINGS

     All notices of meetings of shareholders shall be sent or otherwise given in
accordance with Section 2.5 of these Bylaws not less than ten (10)(or, if sent
by third-class mail pursuant to Section 2.5 of these Bylaws, not less than
thirty (30)) nor more than sixty (60) days before the date of the meeting to
each shareholder entitled to vote thereat.  Such notice shall state the place,
date, and hour of the meeting and (i) in the case of a special meeting, the
general nature of the business to be transacted, and not business other than
that specified in the notice may be transacted, or (ii) in the case of the
annual meeting, those matters which the Board of Directors, at the time of the
mailing of the notice, intends to present for action by the shareholders, but,
subject to the provisions of the next paragraph of this Section 2.4, any proper
matter may be presented at the meeting for such action.  The notice of any
meeting at which Directors are to be elected shall include the names of nominees
intended at the time of the notice to be presented by the Board for election.

     If action is proposed to be taken at any meeting for approval of (i) a
contract or transaction in which a director has a direct or indirect financial
interest, pursuant to Section 310 of the California Corporations Code (the
"Code"), (ii) an amendment of the Articles of Incorporation, pursuant to Section
902 of the Code, (iii) a reorganization of the corporation, pursuant to Section
1201 of the Code, (iv) a voluntary dissolution of the corporation, pursuant to
Section 1900 of the Code, or (v) a distribution in dissolution other than in
accordance with the rights of any outstanding preferred shares, pursuant to
Section 2007 of the Code, then the notice shall also state the general nature 
of that proposal.

     2.5  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

     Notice of a shareholders' meeting shall be given either personally or by
first-class mail, or, if the corporation has outstanding shares held of record
by five hundred (500) or more persons (determined as provided in Section 605 of
the Code) on the record date for the shareholders' meeting, notice may be sent
by third-class mail, or other means of written communication, addressed to the
shareholder at the address of the shareholder appearing on the books of the
corporation or given by the shareholder to the corporation for the purpose of
notice; or if no such address appears or is given, at the place where the
principal executive office of the corporation is located or by publication at
least once in a newspaper of general circulation in the county in which the
principal executive office is located.  The notice shall be deemed to have been
given at the time when delivered personally or deposited in the mail or sent by
other means of written communication.

     If any notice (or any report referenced in Article VII of these Bylaws)
addressed to a shareholder at the address of such shareholder appearing on the
books of the corporation is returned to the corporation by the United States
Postal Service marked to indicate that the United States Postal Service is
unable to deliver the notice to the shareholder at that address, all future
notices or reports shall be deemed to have been duly given without further
mailing is the same shall be available to the shareholder upon written demand of
the shareholder at the principal executive office of the corporation for a
period of one (1) year from the date of the giving of the notice.

     An affidavit of mailing of any notice or report in accordance with the
provisions of this Section 2.5, executed by the Secretary, Assistant Secretary
or any transfer agent, shall be prima facie evidence of the giving of the notice
or report.

<PAGE>

     2.6  QUORUM

     Unless otherwise provided in the Articles of Incorporation of the
corporation, a majority of the shares entitled to vote, represented in person or
by proxy, shall constitute a quorum at a meeting of the shareholders.  The
shareholders present at a duly called or held meeting at which a quorum is
present may continue to transact business until adjournment notwithstanding the
withdrawal of enough shareholders to leave less than a quorum, if any action
taken (other than adjournment) is approved by at least a majority of the shares
required to constitute a quorum.

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

     2.7  ADJOURNED MEETING; NOTICE

     Any shareholders' meeting, annual or special, whether or not a quorum is
present, may be adjourned from time to time by the vote of the majority of the
shares represented at that meeting, either in person or by proxy.

     When any meeting of shareholders, either annual or special, is adjourned to
another time or place, notice need not be given of the adjourned meeting if its
time and place are announced at the meeting at which the adjournment is taken.
However, if the adjournment is for more than forty-five (45) days from the date
set for the original meeting or if a new record date for the adjourned meeting
is fixed, a notice of the adjourned meeting shall be given to each shareholder
of record entitled to vote at the adjourned meeting in accordance with the
provisions of Section 2.4 and 2.5 of these Bylaws.  At any adjourned meeting the
corporation may transact any business which might have been transacted at the
original meeting.

     2.8  VOTING

     The shareholders entitled to vote at any meeting of shareholders shall be
determined in accordance with the provisions of Section 2.11 of these Bylaws,
subject to the provisions of Sections 702 through 704 of the Code (relating to
voting shares held by a fiduciary, in the name of a corporation, or in joint
ownership).

     Elections for directors and voting on any other matter at a shareholders'
meeting need not be by ballot unless a shareholder demands election by ballot at
the meeting and before the voting begins.

     Except as provided in the last paragraph of this Section 2.8, or as may be
otherwise provided in the Articles of Incorporation, each outstanding share,
regardless of class, shall be entitled to one vote on each matter submitted to a
vote of the shareholders.  Any holder of shares entitled to vote on any matter
may vote part of the shares in favor of the proposal and refrain from voting the
remaining shares or may vote them against the proposal other than elections to
office, but, if the shareholder fails to specify the number of shares such
shareholder is voting affirmatively, it will be conclusively presumed that the
shareholder's approving vote is with respect to all shares which the shareholder
is entitled to vote.

     The affirmative vote of the majority of the shares represented and voting
at a duly held meeting at which a quorum is present (which shares voting
affirmatively also constitute at least a majority of the required quorum) shall
be the act of the shareholders, unless the vote of a greater number or voting by
classes is required by the Code or by the Articles of Incorporation.



                                        3

<PAGE>

    At a shareholders' meeting at which directors are to be elected, a 
shareholder shall be entitled to cumulate votes either (i) by giving one 
candidate a number of votes equal to the number of directors to be elected 
multiplied by the number of votes to which that shareholder's shares are 
normally entitled or (ii) by distributing the shareholder's votes on the same 
principle among as many candidates as the shareholder thinks fit, if the 
candidate or candidates' names have been placed in nomination prior to the 
voting and the shareholder has given notice prior to the voting of the 
shareholder's intention to cumulate the shareholder's votes.  If any one 
shareholder has given such a notice, then every shareholder entitled to vote 
may cumulate votes for candidates in nomination.  The candidates receiving 
the highest number of affirmative votes, up to the number of directors to be 
elected, shall be elected; votes against any candidate and votes withheld 
shall have no legal effect.

    2.9  VALIDATION OF MEETINGS; WAIVER OF NOTICE; CONSENT

    The transactions of any meeting of shareholders, either annual or 
special, however called and noticed, and wherever held, are as valid as 
though they had been taken at a meeting duly held after regular call and 
notice, if a quorum be present either in person or by proxy, and if, either 
before or after the meeting, each of the persons entitled to vote, not 
present in person or by proxy, signs a written waiver of notice or a consent 
to the holding of the meeting or an approval of the minutes thereof.  Neither 
the business to be transacted at nor the purpose of any annual or special 
meeting of shareholders need be specified in any written waiver of notice or 
consent to the holding of the meeting or approval of the minutes thereof, 
except that if action is taken or proposed to be taken for approval of any of 
those matters specified in the second paragraph of Section 2.4 of these 
Bylaws, the waiver of notice or consent or approval shall state the general 
nature of the proposal.  All such waivers, consents, and approvals shall be 
filed with the corporate records or made a part of the minutes of the meeting.

    Attendance of a person at a meeting shall constitute a waiver of notice 
of and presence at that meeting, except when the person objects, at the 
beginning of the meeting, to the transaction of any business because the 
meeting is not lawfully called or convened and except that attendance at a 
meeting is not a waiver of any right to object to the consideration of 
matters required by the Code to be included in the notice of such meeting but 
not so included, if such objection is expressly made at the meeting.

    2.10 SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

    Any action which may be taken at any annual or special meeting of 
shareholders may be taken without a meeting and without prior notice, if a 
consent in writing, setting forth the action so taken, shall be signed by the 
holders of outstanding shares having not less than the minimum number of 
votes that would be necessary to authorize or take such action at a meeting 
at which all shares entitled to vote thereon were present and voted.

    Directors may not be elected by written consent except by unanimous 
written consent of all shares entitled to vote for the election of directors. 
 However, a director may be elected at any time to fill any vacancy on the 
Board of Directors, provided that it was not created by removal of a 
directors and that it has not been filled by the directors, by the written 
consent of the holders of a majority of the outstanding shares entitled to 
vote for the election of directors.

    All such consents shall be maintained in the corporate records.  Any 
shareholder giving a written consent, or the shareholder's proxy holders, or 
a transferee of the shares, or a personal representative of the shareholder, 
or their respective proxy holders, may revoke the consent by a writing 
received by the Secretary of the corporation before written consents of the 
number of shares required to authorize the proposed action have been filed 
with the Secretary.

    If the consents of all shareholders entitled to vote have not been 
solicited in writing, the Secretary shall give prompt notice of any corporate 
action approved by the shareholders without a meeting by less than


                                          4

<PAGE>

unanimous written consent to those shareholders entitled to vote who have not 
consented in writing.  Such notice shall be given in the manner specified in 
Section 2.5 of these Bylaws.  In the case of approval of (i) a contract or 
transaction in which a director has a direct or indirect financial interest, 
pursuant to Section 310 of the Code, (ii) indemnification of a corporate 
"agent," pursuant to Section 317 of the Code, (iii) a reorganization of the 
corporation, pursuant to Section 1201 of the Code, and (iv) a distribution in 
dissolution other than in accordance with the rights of outstanding preferred 
shares, pursuant to Section 2007 of the Code, the notice shall be given at 
least ten (10) days before the consummation of any action authorized by that 
approval, unless the consents of all shareholders entitled to vote have been 
solicited in writing.

    2.11 RECORD DATE FOR SHAREHOLDER NOTICE; VOTING; GIVING CONSENTS

    In order that the corporation may determine the shareholders entitled to 
notice of any meeting or to vote, the Board of Directors may fix, in advance, 
a record date, which shall not be more than sixty (60) days nor less than ten 
(10) days prior to the date of such meeting nor more than sixty (60) days 
before any other action.  Shareholders at the close of business on the record 
date are entitled to notice and to vote, as the case may be, notwithstanding 
any transfer of any shares on the books of the corporation after the record 
date, except as otherwise provided in the Articles of Incorporation or the 
Code.

    A determination of shareholders of record entitled to notice of or to 
vote at a meeting of shareholders shall apply to any adjournment of the 
meeting unless the Board of Directors fixes a new record date for the 
adjourned meeting, but the Board of Directors shall fix a new record date if 
the meeting is adjourned for more than forty-five (45) days from the date set 
for the original meeting.

    If the Board of Directors does not so fix a record date:

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

         (b)  The record date for determining shareholders entitled to give 
consent to corporate action in writing without a meeting, (i) when no prior 
action by the Board has been taken, shall be the day on which the first 
written consent is given, or (ii) when prior action by the Board has been 
taken, shall be at the close of business on the day on which the Board adopts 
the resolution relating thereto, or the sixtieth (60th) day prior to the date 
of such other action, whichever is later.

    The record date for any other purpose shall be as provided in Section 8.1 
of these Bylaws.


                                          5

<PAGE>

    2.12 PROXIES

    Every person entitled to vote for directors, or on any other matter, 
shall have the right to do so either in person or by one or more agents 
authorized by a written proxy signed by the person and filed with the 
Secretary of the corporation.  A proxy shall be deemed signed if the 
shareholder's name or other authorization is placed on the proxy (whether by 
manual signature, typewriting, telegraphic or electronic transmission or 
otherwise) by the shareholder or the shareholder's attorney-in-fact.  A 
validly executed proxy which does not state that it is irrevocable shall 
continue in full force and effect unless (i) the person who executed the 
proxy revokes it prior to the time of voting by delivering a writing to the 
corporation stating that the proxy is revoked or by executing a subsequent 
proxy and presenting it to the meeting or by attendance at such meeting and 
voting in person, or (ii) written notice of death or incapacity of the maker 
of that proxy is received by the corporation before the vote pursuant to that 
proxy is counted; provided, however, that no proxy shall be valid after the 
expiration of eleven (11) months from the date thereof, unless otherwise 
provided in the proxy.  The dates contained on the forms of proxy 
presumptively determine the order of execution, regardless of the postmark 
dates on the envelopes in which they are mailed. The revocability of a proxy 
that states on its face that it is irrevocable shall be governed by the 
provisions of Sections 705(e) and 705(f) of the Code.

    2.13 INSPECTORS OF ELECTION

    In advance of any meeting of shareholders, the Board of Directors may 
appoint inspectors of election to act at the meeting and any adjournment 
thereof.  If inspectors of election are not so appointed or designated or if 
any persons so appointed fail to appear or refuse to act, then the Chairman 
of the meeting may, and on the request of any shareholder or a shareholder's 
proxy shall, appoint inspectors of election (or persons to replace those who 
so fail to appear) at the meeting.  The number of inspectors shall be either 
one (1) or three (3).  If appointed at a meeting on the request of one (1) or 
more shareholders or proxies, the majority of shares represented in person or 
by proxy shall determine whether one (1) or three (3) inspectors are to be 
appointed.

    The inspectors of election shall determine the number of shares 
outstanding and the voting power of each, the shares represented at the 
meeting, the existence of a quorum, and the authenticity, validity, and 
effect of proxies, receive votes, ballots or consents, hear and determine all 
challenges and questions in any way arising in connection with the right to 
vote, count and tabulate all votes or consents, determine when the polls 
shall close, determine the result and do any other acts that may be proper to 
conduct the election or vote with fairness to all shareholders.

                                      DIRECTORS

    3.1  POWERS

    Subject to the provisions of the Code and any limitations in the Articles 
of Incorporation and these Bylaws relating to action required to be approved 
by the shareholders or by the outstanding shares, the business and affairs of 
the corporation shall be managed and all corporate powers shall be exercised 
by or under the direction of the Board of Directors.  The Board may delegate 
the management of the day-to-day operation of the business of the corporation 
to a management company or other person provided that the business and 
affairs of the corporation shall be managed and all corporate powers shall be 
exercised under the ultimate direction of the Board.

    3.2   NUMBER OF DIRECTORS

    The authorized number of directors of the corporation shall be not less
than three (3) nor more than five (5) (which in no case shall be greater than
two times the stated minimum minus one), and the exact number of directors shall
be four (4) until changed, within the limits specified above, by a resolution
amending such exact number, duly adopted by the Board of Directors or by the
shareholders.  The minimum and maximum number of directors may be changed, or a
definite number may be fixed without provision for an indefinite number, by a
duly adopted amendment to the Articles of Incorporation or by an amendment to
this Bylaw duly adopted by the vote or written consent of holders of a majority 
of the outstanding shares entitled to vote; provided, however, that an amendment
reducing the fixed number or the minimum number of directors to a number less
than five (5) cannot be adopted if the votes cast against its adoption at a
meeting, or the shares not consenting in the case of an action by written
consent, are equal to more than sixteen and two-thirds percent (16-2/3%) of the
outstanding shares entitled to vote thereon.

    No reduction of the authorized number of directors shall have the effect 
of removing any director before that director's term of office expires.

    3.3   ELECTION AND TERM OF OFFICE OF DIRECTORS

    At each annual meeting of shareholders, directors shall be elected to 
hold office until the next annual meeting.  Each director, including a 
director elected to fill a vacancy, shall hold office until the expiration of 
the term for which elected and until a successor has been elected and 
qualified, except in the case of the death, resignation, or removal of such a 
director.

    3.4   REMOVAL

    The entire Board of Directors or any individual director may be removed 
from office without cause by the affirmative vote of a majority of the 
outstanding shares entitled to vote on such removal; provided, however, that 
unless the entire Board is removed, no individual director may be removed 
when the votes cast against such director's removal, or not consenting in 
writing to such removal, would be sufficient to elect that director if voted 
cumulatively at an election at which the same total number of votes cast were 
cast (or, if such action is taken by written consent, all shares entitled to 
vote were voted) and the entire number of directors authorized at the time of 
such director's most recent election were then being elected.

    3.5   RESIGNATION AND VACANCIES

    Any director may resign effective upon giving oral or written notice to 
the Chairman of the Board, the President, the Secretary or the Board of 
Directors, unless the notice specifies a later time for the effectiveness of 
such resignation.  If the resignation of a director is effective at a future 
time, the Board of Directors may elect a successor to take office when the 
resignation becomes effective.

    Vacancies on the Board of Directors may be filled by a majority of the 
remaining directors, or if the number of directors then in office is less 
than a quorum by (i) unanimous written consent of the directors then in 
office, (ii) the affirmative vote of a majority of the directors then in 
office at a meeting held pursuant to notice or waivers of notice, or (iii) a 
sole remaining director; however, a vacancy created by the removal of a 
director by the vote or written consent of the shareholders or by court order 
may be filled only by the affirmative vote of a majority of the shares 
represented and voting at a duly held meeting at which a quorum is present 
(which shares voting affirmatively also constitute at least a majority of the 
required quorum), or by the unanimous written

                                          7

<PAGE>

consent of all shares entitled to vote thereon.  Each director so elected shall
hold office until the next annual meeting of the shareholders and until a
successor has been elected and qualified, or until his or her death, resignation
or removal.

    A vacancy or vacancies in the Board of Directors shall be deemed to exist 
(i) in the event of the death, resignation or removal of any director, (ii) 
if the Board of Directors by resolution declares vacant the office of a 
director who has been declared of unsound mind by an order of court or 
convicted of a felony, (iii) if the authorized number of directors is 
increased, or (iv) if the shareholders fail, at any meeting of shareholders 
at which any director or directors are elected, to elect the full authorized 
number of directors to be elected at that meeting.

    The shareholders may elect a director or directors at any time to fill any
vacancy or vacancies not filled by the directors, but any such election by
written consent, other than to fill a vacancy created by removal, shall require
the consent of the holders of a majority of the outstanding shares entitled to
vote thereon.  A director may not be elected by written consent to fill a
vacancy created by removal except by unanimous consent of all shares entitled to
vote for the election of directors.

    3.6   PLACE OF MEETINGS; MEETINGS BY TELEPHONE

    Regular meetings of the Board of Directors may be held at any place within

resolution of the Board.  In the absence of such a designation, regular meetings

meetings of the Board may be held at any place within or outside the State of
California that has been designated in the notice of the meeting or, if not
stated in the notice or if there is no notice, at the principal executive office
of the corporation.

    Members of the Board may participate in a meeting through the use of
conference telephone or similar communications equipment, so long as all
directors participating in such meeting can hear one another.  Participation in
a meeting pursuant to this paragraph constitutes presence in person at such
meeting.

the time and place of such meetings are fixed by the Board of Directors.

    3.8   SPECIAL MEETINGS; NOTICE

the Board of Directors for any purpose or purposes may be called at any time by
the Chairman of the Board, the President, any Vice President, the Secretary or

    Notice of the time and place of special meetings shall be delivered 
personally or by telephone to each director or sent by first-class mail,
telegram, charges prepaid, or by telecopier, addressed to each director at that
director's address as it is shown on the records of the corporation.  If the
notice is mailed, it shall be deposited in the United States mail at least four
(4) days before the time of the holding of the meeting.  If the notice is
delivered personally or by telephone or by telecopier or telegram, it shall be
delivered personally or by telephone or by telecopier or to the telegraph
company at least forty-eight (48) hours before the time of the holding of the
meeting.  Any oral notice given personally or by telephone may be communicated

the director.  The notice need not specify the purpose of the meeting.

    3.9   QUORUM

    A majority of the authorized number of directors shall constitute a 
quorum for the transaction of business, except to adjourn as provided in 
Section 3.11 of these Bylaws.  Every act or decision done or made by a 
majority of the directors present at a meeting duly held at which a quorum is 
present is the act of the Board of Directors, subject to the provisions of 
Section 310 of the Code (as to approval of contracts or transactions in which 
a director has a direct or indirect material financial interest), Section 311 
of the Code (as to appointment of committees), Section 317(e) of the Code (as 
to indemnification of directors), the Articles of Incorporation, and other 
applicable law.

    A meeting at which a quorum is initially present may continue to transact
business notwithstanding the withdrawal of directors, if any action taken is
approved by at least a majority of the required quorum for such meeting.

    3.10  WAIVER OF NOTICE

    Notice of a meeting need not be given to any director who signs a waiver of
notice or a consent to holding the meeting or an approval of the minutes
thereof, whether before or after the meeting, or who attends the meeting without
protesting, prior thereto or at its commencement, the lack of notice to such
director.  All such waivers, consents, and approvals shall be filed with the
corporate records or made a part of the minutes of the meeting.  A waiver of
notice need not specify the purpose of any regular or special meeting of the
Board of Directors.

    3.11  ADJOURNMENT

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

    3.12  NOTICE OF ADJOURNMENT

any adjournment to another time and place shall be given prior to the time of

the adjournment.

    3.13  BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING

    Any action required or permitted to be taken by the Board of Directors may
be taken without a meeting, if all members of the Board individually or
collectively consent in writing to such action.  Such written consent or
consents shall be filed with the minutes of the proceedings of the Board.  Such
action by written consent shall have the same force and effect as a unanimous
vote of the Board of Directors.

    3.14  FEES AND COMPENSATION OF DIRECTORS

    Directors and members of committees may receive such compensation, if any,
for their services and such reimbursement of expenses as may be fixed or
determined by resolution of the Board of Directors.  This Section 3.14 shall not
be construed to preclude any director from serving the corporation in any other
capacity as an officer, agent, employee or otherwise and receiving compensation
for those services.

accordance with the Code, the corporation may, upon the approval of the Board 
of Directors alone, make loans of money or property to, or guarantee the 
obligations of, any officer of the corporation or of its parent, if any, 
whether or not a director, or adopt an employee benefit plan or plans 
authorizing such loans or guaranties provided that (i) the Board of Directors 
determines that such a loan or guaranty or plan may reasonably be expected to 
benefit the corporation, (ii) the corporation has outstanding shares held of 
record by 100 or more persons (determined as provided in Section 605 of the 
Code) on the date of approval by the Board of Directors, and (iii) the

the vote of any interested director or directors.  Notwithstanding the 
foregoing, the corporation shall have the power to make loans permitted by 
the Code.

The Board may designate one or more directors as alternate members of any
committee, who may replace any absent member at any meeting of the committee. 
The appointment of members or alternate members of a committee requires the vote

VI

                INDEMNIFICATION OF DIRECTORS, OFFICERS, EMPLOYEES,
                                 AND OTHER AGENTS

     6.1  INDEMNIFICATION OF DIRECTORS

     The corporation shall, to the maximum extent and in the manner permitted 
by the Code, indemnify each of its directors against expenses (as defined in 
Section 317(a) of the Code), judgments, fines, settlements, and other amounts 
actually and reasonably incurred in connection with any proceeding (as 
defined in Section 317(a) of the Code), arising by reason of the fact that 
such person is or was a director of the corporation. For purposes of this 
Article VI, a "director" of the corporation includes any person (i) who is or 
was a director of the corporation, (ii) who is or was serving at the request 
of the corporation as a director of another foreign or domestic corporation, 
partnership, joint venture, trust or other enterprise, or (iii) who was a 
director of a corporation which was a predecessor corporation of the 
corporation or of another enterprise at the request of such predecessor 
corporation.

     6.2  INDEMNIFICATION OF OTHERS

     The corporation shall have the power, to the extent and in the manner 
permitted by the Code, to indemnify each of its employees, officers, and 
agents (other than directors) against expenses (as defined in Section 317(a) 
of the Code), judgments, fines, settlements, and other amounts actually and 
reasonably incurred in connection with any proceeding (as defined in 
Section 317(a) of the Code), arising by reason of the fact that such person is 
or was an employee, officer, or agent of the corporation. For purposes of this 
Article VI, an "employee" or "officer" or "agent" of the corporation (other 
than a director) includes any person (i) who is or was an employee, officer, 
or agent of the corporation, (ii) who is or was serving at the request of the 
corporation as an employee, officer, or agent of another foreign or domestic 
corporation, partnership, joint venture, trust or other enterprise, or 
(iii) who was an employee, officer, or agent of a corporation which was a 
predecessor corporation of the corporation or of another enterprise at the 
request of such predecessor corporation.

                                      13
<PAGE>

     6.3  PAYMENT OF EXPENSES IN ADVANCE

     Expenses and attorneys' fees incurred in defending any civil or criminal 
action or proceeding for which indemnification is required pursuant to 
Section 6.1, or if otherwise authorized by the Board of Directors, shall be 
paid by the corporation in advance of the final disposition of such action or 
proceeding upon receipt of an undertaking by or on behalf of the indemnified 
party to repay such amount if it shall ultimately be determined that the 
indemnified party is not entitled to be indemnified as authorized in this 
Article VI.

     6.4  INDEMNITY NOT EXCLUSIVE

     The indemnification provided by this Article VI shall not be deemed 
exclusive of any other rights to which those seeking indemnification may be 
entitled under any Bylaw, agreement, vote of shareholders or directors or 
otherwise, both as to action in an official capacity and as to action in 
another capacity while holding such office. The rights to indemnity hereunder 
shall continue as to a person who has ceased to be a director, officer, 
employee, or agent and shall inure to the benefit of the heirs, executors, 
and administrators of the person.

     6.5  INSURANCE INDEMNIFICATION

     The corporation shall have the power to purchase and maintain insurance 
on behalf of any person who is or was a director, officer, employee or agent 
of the corporation against any liability asserted against or incurred by such 
person in such capacity or arising out of that person's status as such, 
whether or not the corporation would have the power to indemnify that person 
against such liability under the provisions of this Article VI.

     6.6  CONFLICTS

     No indemnification or advance shall be made under this Article VI, 
except where such indemnification or advance is mandated by law or the
order, judgment or decree of any court of competent jurisdiction, in any 
circumstance where it appears:

          (1)  That it would be inconsistent with a provision of the Articles 
of Incorporation, these Bylaws, a resolution of the shareholders or an 
agreement in effect at the time of the accrual of the alleged cause of the 
action asserted in the proceeding in which the expenses were incurred or 
other amounts were paid, which prohibits or otherwise limits indemnification; 
or

          (2)  That it would be inconsistent with any condition expressly 
imposed by a court in approving a settlement.

     6.7  RIGHT TO BRING SUIT

     If a claim under this Article is not paid in full by the corporation 
within 90 days after a written claim has been received by the corporation 
(either because the claim is denied or because no determination is made), the 
claimant may at any time thereafter bring suit against the corporation to 
recover the unpaid amount of the claim and, if successful in whole or in 
part, the claimant shall also be entitled to be paid the expenses of 
prosecuting such claim. The corporation shall be entitled to raise as a 
defense to any such action that the claimant has not met the standards of 
conduct that make it permissible under the Code for the corporation to 
indemnify the claimant for the claim. Neither the failure of the corporation 
(including its Board of Directors, independent legal counsel, or its 
shareholders) to have made a determination prior to the commencement of such 
action that indemnification of the claimant is permissible in the 
circumstances because he or she has met the

                                      14
<PAGE>

applicable standard of conduct, if any, nor an actual determination by the 
corporation (including its Board of Directors, independent legal counsel, or 
its shareholders) that the claimant has not met the applicable standard of 
conduct, shall be a defense to such action or create a presumption for the 
purposes of such action that the claimant has not met the applicable standard 
of conduct.

     6.8  INDEMNITY AGREEMENTS

     The Board of Directors is authorized to enter into a contract with any 
director, officer, employee or agent of the corporation, or any person who is 
or was serving at the request of the corporation as a director, officer, 
employee or agent of another corporation, partnership, joint venture, trust 
or other enterprise, including employee benefit plans, or any person who was 
a director, officer, employee or agent of a corporation which was a 
predecessor corporation of the corporation or of another enterprise at the 
request of such predecessor corporation, providing for indemnification rights 
equivalent to or, if the Board of Directors so determines and to the extent 
permitted by applicable law, greater than, those provided for in this Article 
VI.

     6.9  AMENDMENT, REPEAL OR MODIFICATION

     Any amendment, repeal or modification of any provision of this Article 
VI shall not adversely affect any right or protection of a director or agent 
of the corporation existing at the time of such amendment, repeal or 
modification.

VII

                              RECORDS AND REPORTS

     7.1  MAINTENANCE AND INSPECTION OF SHARE REGISTER

     The corporation shall keep either at its principal executive office or 
at the office of its transfer agent or registrar (if either be appointed), as 
determined by resolution of the Board of Directors, a record of its 
shareholders listing the names and addresses of all shareholders and the 
number and class of shares held by each shareholder.

     A shareholder or shareholders of the corporation holding at least five 
percent (5%) in the aggregate of the outstanding voting shares of the 
corporation or who hold at least one percent (1%) of such voting shares and 
have filed a Schedule 14B with the United States Securities and Exchange 
Commission relating to the election of directors, shall have an absolute 
right to do either or both of the following (i) inspect and copy the record 
of shareholders' names, addresses, and shareholdings during usual business 
hours upon five (5) days' prior written demand upon the corporation, or (ii) 
obtain from the transfer agent for the corporation, upon written demand and 
upon the tender of such transfer agent's usual charges for such list (the 
amount of which charges shall be stated to the shareholder by the transfer 
agent upon request), a list of the shareholders' names and addresses who are 
entitled to vote for the election of directors, and their shareholdings, as 
of the most recent record date for which it has been compiled or as of a date 
specified by the shareholder subsequent to the date of demand. The list shall 
be made available on or before the later of five (5) business days after the 
demand is received or the date specified therein as the date as of which the 
list is to be compiled.

                                      15
<PAGE>

     The record of shareholders shall also be open to inspection and copying 
by any shareholder or holder of a voting trust certificate at any time during 
usual business hours upon written demand on the corporation, for a purpose 
reasonably related to the holder's interest as a shareholder or holder of a 
voting trust certificate.

     Any inspection and copying under this Section 7.1 may be made in person 
or by an agent or attorney of the shareholder or holder of a voting trust 
certificate making the demand.

     7.2  MAINTENANCE AND INSPECTION OF BYLAWS

     The corporation shall keep at its principal executive office or, if its 
principal executive office is not in the State of California, at its 
principal business office in California, the original or a copy of these 
Bylaws as amended to date, which shall be open to inspection by the 
shareholders at all reasonable times during office hours.  If the principal 
executive office of the corporation is outside the State of California and 
the corporation has no principal business office in such state, then it 
shall, upon the written request of any shareholder, furnish to such 
shareholder a copy of these Bylaws as amended to date.

     7.3  MAINTENANCE AND INSPECTION OF OTHER CORPORATE RECORDS

     The accounting books and records and the minutes of proceedings of the 
shareholders and the Board of Directors, and committees of the Board of 
Directors shall be kept at such place or places as are designated by the 
Board of Directors or, in absence of such designation, at the principal 
executive office of the corporation.  The minutes shall be kept in written 
form, and the accounting books and records shall be kept either in written 
form or in any other form capable of being converted into written form.

     The minutes and accounting books and records shall be open to inspection 
upon the written demand on the corporation of any shareholder or holder of a 
voting trust certificate at any reasonable time during usual business hours, 
for a purpose reasonably related to such holder' interests as a shareholder 
or as the holder of a voting trust certificate.  Such inspection by a 
shareholder or holder of a voting trust certificate may be made in person or 
by an agent or attorney and the right of inspection includes the right to 
copy and make extracts. Such rights of inspection shall extend to the records 
of each subsidiary corporation of the corporation.

     7.4  INSPECTION BY DIRECTORS

     Every director shall have the absolute right at any reasonable time to 
inspect and copy all books, records, and documents of every kind and to 
inspect the physical properties of the corporation and each of its subsidiary 
corporations, domestic or foreign.  Such inspection by a director may be made 
in person or by an agent or attorney and the right of inspection includes the 
right to copy and make extracts.

     7.5  ANNUAL REPORT TO SHAREHOLDERS; WAIVER

     The Board of Directors shall cause an annual report to be sent to the 
shareholders not later than one hundred twenty (120) days after the close of 
the fiscal year adopted by the corporation. Such report shall be sent to the 
shareholders at least fifteen (15) (or, if sent by third-class mail, 
thirty-five (35)) days prior to the annual meeting of shareholders to be held 
during the next fiscal year and in the manner specified in Section 2.5 of 
these Bylaws for giving notice to shareholders of the corporation.

     The annual report shall contain a balance sheet as of the end of the 
fiscal year and an income statement and statement of changes in financial 
position for the fiscal year, accompanied by any report thereon of 
independent accountants or, if there is no such report, the certificate of an 
authorized officer of the corporation that the statements were prepared 
without audit from the books and records of the corporation.

                                       16
<PAGE>

     The foregoing requirement of an annual report shall be waived so long as 
the shares of the corporation are held by fewer than one hundred (100) 
holders of record.

     7.6  FINANCIAL STATEMENTS

     If no annual report for the fiscal year has been sent to shareholders, 
then the corporation shall, upon the written request of any shareholder made 
more than one hundred twenty (120) days after the close of such fiscal year, 
deliver or mail to the person making the request, within thirty (30) days 
thereafter, a copy of a balance sheet as of the end of such fiscal year and 
an income statement and statement of changes in financial position for such 
fiscal year.

     A shareholder or shareholders holding at least five percent (5%) of the 
outstanding shares of any class of the corporation may make a written request 
to the corporation for an income statement of the corporation for the 
three-month, six-month or nine-month period of the current fiscal year ended 
more than thirty (30) days prior to the date of the request and a balance 
sheet of the corporation as of the end of that period.  The statements shall 
be delivered or mailed to the person making the request within thirty (30) 
days thereafter.  A copy of the statements shall be kept on file in the 
principal office of the corporation for twelve (12) months and it shall be 
exhibited at all reasonable times to any shareholder demanding an examination 
of the statements or a copy shall be mailed to the shareholder.  If the 
corporation has not sent to the shareholders its annual report for the last 
fiscal year, the statements referred to in the first paragraph of this 
Section 7.6 shall likewise be delivered or mailed to the shareholder or 
shareholders within thirty (30) days after the request.

     The quarterly income statements and balance sheets referred to in this 
section shall be accompanied by the report thereon, if any, of any 
independent accounts engaged by the corporation or the certificate of an 
authorized officer of the corporation that the financial statements were 
prepared without audit from the books and records of the corporation.

     7.7  REPRESENTATION OF SHARES OF OTHER CORPORATIONS

     The Chairman of the Board, the President, any Vice President, the Chief 
Financial Officer, the Secretary or Assistant Secretary of this corporation, 
or any other person authorized by the Board of Directors or the President or 
a Vice President, is authorized to vote, represent, and exercise on behalf of 
this corporation all rights incident to any and all shares of any other 
corporation or corporations standing in the name of this corporation.  The 
authority herein granted may be exercised either by such person directly or 
by any other person authorized to do so by proxy or power of attorney duly 
executed by such person having the authority.

VII

                                 GENERAL MATTERS

     8.1  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

     For purposes of determining the shareholders entitled to receive payment 
of any dividend or other distribution or allotment of any rights or entitled 
to exercise any rights in respect of any other lawful action (other than with 
respect to notice or voting at a shareholders meeting or action by 
shareholders by written consent without a meeting), the Board of Directors 
may fix, in advance, a record date, which shall not be more than sixty (60) 
days prior to any such action.  Only shareholders of record at the close of 
business on the record date are entitled to receive the dividend, 
distribution or allotment of rights, or to exercise the rights, as the case

                                       17
<PAGE>


may be, notwithstanding any transfer of any shares on the books of the
corporation after the record date, except as otherwise provided in the Articles
of Incorporation or the Code.

     If the Board of Directors does not so fix a record date, then the record
date for determining shareholders for any such purpose shall be at the close of
business on the day on which the Board adopts the resolution relating thereto or
the sixtieth (60th) day prior to the date of that action, whichever is later.
     
     8.2  CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

     From time to time, the Board of Directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtness that are issued in the
name of or payable to the corporation, and only the persons so authorized shall
sign or endorse those instruments.

     8.3  CORPORATE CONTRACTS AND INSTRUMENTS: HOW EXECUTED

     The Board of Directors, except as otherwise provided in these Bylaws, 
may authorize any officer or officers, or agent or agents, to enter into any 
contract or execute any instrument in the name of and on behalf of the 
corporation; such authority may be general or confined to specific instances. 
Unless so authorized or ratified by the Board of Directors or within the 
agency power of an officer, no officer, agent or employee shall have any 
power or authority to bind the corporation by any contract or engagement or 
to pledge its credit or to render it liable for any purpose or for any amount.

     8.4  CERTIFICATE FOR SHARES

     A certificate or certificates for shares of the corporation shall be issued
to each shareholder when any of such shares are fully paid.  The Board of
Directors may authorize the issuance of certificates for shares partly paid
provided that these certificates shall state the total amount of the
consideration to be paid for them and the amount actually paid.   All
certificates shall be signed in the name of the corporation by the Chairman of
the Board or the Vice Chairman of the Board or the President or a Vice
President and by the Chief Financial Officer or an Assistant Treasurer or the
Secretary or an Assistant Secretary, certifying the number of shares and the
class or series of shares owned by the shareholder.  Any or all of the
signatures on the certificate may be by facsimile.

     In case any officer, transfer agent or registrar who has signed or whose
facsimile signature has been placed on a certificate has ceased to be such
officer, transfer agent or registrar before such certificate is issued, it may
be issued by the corporation with the same effect as if that person were an
officer, transfer agent or registrar at the date of issue.

     8.5  LOST CERTIFICATES

                                       18
<PAGE>

     Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the corporation or its transfer agent or registrar and cancelled
at the same time.  The Board of Directors may, in case any share certificate or
certificate for any other security is lost, stolen or destroyed (as evidenced by
a written affidavit or affirmation of such fact), authorize the issuance of
replacement certificates on such terms and conditions as the Board may require;
the Board may require indemnification of the corporation secured by a bond or
other adequate security sufficient to protect the corporation against any claim
that may be made against it, including any expense or liability, on account of 
the alleged loss, theft or destruction of the certificate or the issuance of the
replacement certificate.

     8.6  CONSTRUCTION; DEFINITIONS

     Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the Code shall govern the construction of these
Bylaws.  Without limiting the generality of this provision, the singular number
includes the plural, the plural number includes the singular, and the term
"person" includes both a corporation and a natural person.

     9.1  AMENDMENT BY SHAREHOLDERS

     New Bylaws may be adopted or these Bylaws may be amended or repealed by the
vote or written consent of holders of a majority of the outstanding shares

consent was filed, shall be stated in said book.

    2.3  SPECIAL MEETING

    A special meeting of the shareholders may be called at any time by the

not less than ten percent (10%) of the votes at that meeting.

facsimile transmission to the chairman of the board, the president, any vice 
president or the secretary of the corporation.  The officer receiving the

the request, then the person or persons requesting the meeting may give the 
notice.  Nothing contained in this paragraph of this Section 2.3 shall be 
construed as limiting, fixing or affecting the time when a meeting of 
shareholders called by action of the board of directors may be held.

    2.4  NOTICE OF SHAREHOLDERS' MEETINGS

    All notices of meetings of shareholders shall be sent or otherwise given 
in accordance with Section 2.5 of these bylaws not less than ten (10) (or, if 
sent by third-class mail pursuant to Section 2.5 of these bylaws, thirty 
(30)) nor more than sixty (60) days before the date of the meeting.  The 
notice shall specify the place, date, and hour of the meeting and (i) in the 
case of a special meeting, the general nature of the business to be 
transacted (no business other than that specified in the notice may be

the board of directors, at the time of giving the notice, intends to present 
for action by the shareholders (but subject to the provisions of the next 
paragraph of this Section 2.4 any proper matter may be presented at the 
meeting for such action).  The notice of any meeting at which directors are 
to be elected shall include the name of any nominee or nominees who, at the 
time of the notice, the board intends to present for election.

    If action is proposed to be taken at any meeting for approval of (i) a 
contract or transaction in which a director has a direct or indirect 
financial interest, pursuant to Section 310 of the Corporations Code of 
California (the "Code"), (ii) an amendment of the articles of incorporation, 
pursuant to Section 902 of the Code, (iii) a reorganization of the 
corporation, pursuant to Section 1201 of the Code, (iv) a voluntary 
dissolution of the corporation, pursuant to Section 1900 of the Code, or (v) 
a distribution in dissolution other than in accordance with the rights of 
outstanding preferred shares, pursuant to Section 2007 of the Code, then the 
notice shall also state the general nature of that proposal.

    2.5  ADVANCE NOTICE OF SHAREHOLDER NOMINEES AND SHAREHOLDER BUSINESS

    To be properly brought before an annual meeting or special meeting, 
nominations for the election of director or other business must be (a) 
specified in the notice of meeting (or any supplement thereto) given by or at 
the direction of the board of directors, (b) otherwise properly brought 
before the meeting by or at the direction of the board of directors, or (c) 
otherwise properly brought before the meeting by a shareholder.  For such 
nominations or other business to be considered properly brought before the 
meeting by a shareholder, such shareholder must have given timely notice and 
in proper form of his intent to bring such business before such meeting.  To 
be timely, such shareholder's notice must be delivered to or mailed and 
received by the secretary of the corporation not less than ninety (90) days 
prior to the meeting; provided, however, that in the event that less than one 
hundred (100) days notice or prior public disclosure of the date of the 
meeting is given or made to shareholders, notice by the shareholder to be 
timely must be so received not later than the close of business on the tenth 
day following the day on which such notice of the date of the meeting was 
mailed or such public disclosure was made.  To be in proper form, a 
shareholder's notice to the secretary shall set forth:

         (a)  the name and address of the shareholder who intends to make the
         nominations or propose the business and, as the case may be, the name
         and address of the person or persons to be nominated or the nature of
         the business to be proposed;

         (b)  a representation that the shareholder is a holder of record of
         stock of the corporation entitled to vote at such meeting and,
         if applicable, intends to appear in person or by proxy at the
         meeting to nominate the person or persons specified in the notice 
         or to introduce the business specified in the notice;

         (c)  if applicable, a description of all arrangements or
         understandings between the shareholder and each nominee and any other
         person or persons (naming such person or persons) pursuant to which
         the nomination or nominations are to be made by the shareholder;

         (d)  such other information regarding each nominee or each matter of
         business to be proposed by such shareholder as would be required to be
         included in a proxy statement filed pursuant to the proxy rules of the
         Securities and Exchange Commission had the nominee been nominated, or
         intended to be nominated, or the matter been proposed, or intended to
         be proposed by the board of directors; and 

         (e)  if applicable, the consent of each nominee to serve as director
         of the corporation if so elected.

foregoing procedure.

<PAGE>

    2.6  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

    Written notice of any meeting of shareholders shall be given either (i) 
personally or (ii) by first-class mail or (iii) by third-class mail but only 
if the corporation has outstanding shares held of record by five hundred 
(500) or more persons (determined as provided in Section 605 of the Code) on 
the record date for the shareholders' meeting, or (iv) by telegraphic or 
other written communication. Notices not personally delivered shall be sent 
charges prepaid and shall be addressed to the shareholder at the address of 
that shareholder appearing on the books of the corporation or given by the 
shareholder to the corporation for the purpose of notice.  If no such address 
appears on the corporation's books or is given, notice shall be deemed to 
have been given if sent to that shareholder by mail or telegraphic or other 
written communication to the corporation's principal executive office, or if 
published at least once in a newspaper of general circulation in the county 
where that office is located.  Notice shall be deemed to have been given at 
the time when delivered personally or deposited in the mail or sent by 
telegram or other means of written communication.

    If any notice addressed to a shareholder at the address of that 
shareholder appearing on the books of the corporation is returned to the 
corporation by the United States Postal Service marked to indicate that the 
United States Postal Service is unable to deliver the notice to the 
shareholder at that address, then all future notices or reports shall be 
deemed to have been duly given without further mailing if the same shall be 
available to the shareholder on written demand of the shareholder at the 
principal executive office of the corporation for a period of one (1) year 
from the date of the giving of the notice.

    An affidavit of the mailing or other means of giving any notice of any 
shareholders' meeting, executed by the secretary, assistant secretary or any 
transfer agent of the corporation giving the notice, shall be prima facie 
evidence of the giving of such notice.

    2.7  QUORUM

    The presence in person or by proxy of the holders of a majority of the 
shares entitled to vote thereat constitutes a quorum for the transaction of 
business at all meetings of shareholders.  The shareholders present at a duly 
called or held meeting at which a quorum is present may continue to do 
business until adjournment, notwithstanding the withdrawal of enough 
shareholders to leave less than a quorum, if any action taken (other than 
adjournment) is approved by at least a majority of the shares required to 
constitute a quorum.

    2.8  ADJOURNED MEETING; NOTICE

    Any shareholders' meeting, annual or special, whether or not a quorum is 
present, may be adjourned from time to time by the vote of the majority of 
the shares represented at that meeting, either in person or by proxy.  In the 
absence of a quorum, no other business may be transacted at that meeting 
except as provided in Section 2.6 of these bylaws.

                                     -4-

<PAGE>

    When any meeting of shareholders, either annual or special, is adjourned 
to another time or place, notice need not be given of the adjourned meeting 
if the time and place are announced at the meeting at which the adjournment 
is taken. However, if a new record date for the adjourned meeting is fixed or 
if the adjournment is for more than forty-five (45) days from the date set 
for the original meeting, then notice of the adjourned meeting shall be 
given.  Notice of any such adjourned meeting shall be given to each 
shareholder of record entitled to vote at the adjourned meeting in accordance 
with the provisions of Sections 2.4 and 2.6 of these bylaws.  At any 
adjourned meeting the corporation may transact any business which might have 
been transacted at the original meeting.

    2.9  VOTING

    The shareholders entitled to vote at any meeting of shareholders shall be 
determined in accordance with the provisions of Section 2.11 of these bylaws, 
subject to the provisions of Sections 702 through 704 of the Code (relating 
to voting shares held by a fiduciary, in the name of a corporation or in 
joint ownership).

    The shareholders' vote may be by voice vote or by ballot; provided, 
however, that any election for directors must be by ballot if demanded by any 
shareholder at the meeting and before the voting has begun.

    Except as provided in the last paragraph of this Section 2.9, or as may 
be otherwise provided in the articles of incorporation, each outstanding 
share, regardless of class, shall be entitled to one vote on each matter 
submitted to a vote of the shareholders. Any shareholder entitled to vote on 
any matter may vote part of the shares in favor of the proposal and refrain 
from voting the remaining shares or, except when the matter is the election 
of directors, may vote them against the proposal; but, if the shareholder 
fails to specify the number of shares which the shareholder is voting 
affirmatively, it will be conclusively presumed that the shareholder's 
approving vote is with respect to all shares which the shareholder is 
entitled to vote.

    If a quorum is present, the affirmative vote of the majority of the 
shares represented and voting at a duly held meeting (which shares voting 
affirmatively also constitute at least a majority of the required quorum) 
shall be the act of the shareholders, unless the vote of a greater number or 
a vote by classes is required by the Code or by the articles of incorporation.

    At a shareholders' meeting at which directors are to be elected, a 
shareholder shall be entitled to cumulate votes (i.e., cast for any candidate 
a number of votes greater than the number of votes which such shareholder 
normally is entitled to cast) if the candidates' names have been placed in 
nomination prior to commencement of the voting and the shareholder has given 
notice prior to commencement of the voting of the shareholder's intention to 
cumulate votes. If any shareholder has given such a notice, then every 
shareholder entitled to vote may cumulate votes for candidates in nomination 
either (i) by giving one candidate a number of votes equal to the number of 
directors to be elected multiplied by the number of votes to which that 
shareholder's shares are normally entitled or (ii) by distributing the 
shareholder's votes on the same principle among any or all of the candidates, 
as the shareholder thinks fit. The candidates receiving the highest number of 
affirmative votes, up to the

                                     -5-

<PAGE>

number of directors to be elected, shall be elected; votes against any 
candidate and votes withheld shall have no legal effect.  Effective upon such 
time as (i) shares of the capital stock of the corporation are designated as 
qualified for trading as National Market System securities on the National 
Association of Securities Dealers, Inc. Automated Quotation System (or any 
successor national system) ("Qualified Public Offering") and (ii) the 
corporation has at least 800 holders of shares of its capital stock, 
shareholders shall no longer be entitled to cumulate votes.

    2.10 VALIDATION OF MEETINGS; WAIVER OF NOTICE; CONSENT

    The transactions of any meeting of shareholders, either annual or 
special, however called and noticed, and wherever held, shall be as valid as 
though they had been taken at a meeting duly held after regular call and 
notice, if a quorum be present either in person or by proxy, and if, either 
before or after the meeting, each person entitled to vote, who was not 
present in person or by proxy, signs a written waiver of notice or a consent 
to the holding of the meeting or an approval of the minutes thereof.  The 
waiver of notice or consent or approval need not specify either the business 
to be transacted or the purpose of any annual or special meeting of 
shareholders, except that if action is taken or proposed to be taken for 
approval of any of those matters specified in the second paragraph of Section 
2.4 of these bylaws, the waiver of notice or consent or approval shall state 
the general nature of the proposal.  All such waivers, consents, and 
approvals shall be filed with the corporate records or made a part of the 
minutes of the meeting.

    Attendance by a person at a meeting shall also constitute a waiver of 
notice of and presence at that meeting, except when the person objects at the 
beginning of the meeting to the transaction of any business because the 
meeting is not lawfully called or convened.  Attendance at a meeting is not a 
waiver of any right to object to the consideration of matters required by the 
Code to be included in the notice of the meeting but not so included, if that 
objection is expressly made at the meeting.

    2.11 SHAREHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING

    Any action which may be taken at any annual or special meeting of 
shareholders may be taken without a meeting and without prior notice, if a 
consent in writing, setting forth the action so taken, is signed by the 
holders of outstanding shares having not less than the minimum number of 
votes that would be necessary to authorize or take that action at a meeting 
at which all shares entitled to vote on that action were present and voted.

    In the case of election of directors, such a consent shall be effective 
only if signed by the holders of all outstanding shares entitled to vote for 
the election of directors.  However, a director may be elected at any time to 
fill any vacancy on the board of directors, provided that it was not created 
by removal of a director and that it has not been filled by the directors, by 
the written consent of the holders of a majority of the outstanding shares 
entitled to vote for the election of directors.

    All such consents shall be maintained in the corporate records. Any 
shareholder giving a written consent, or the shareholder's proxy holders, or 
a transferee of the shares, or a personal representative of the shareholder, 
or their respective proxy holders, may revoke the consent by a

                                     -6-

<PAGE>

writing received by the secretary of the corporation before written consents 
of the number of shares required to authorize the proposed action have been 
filed with the secretary.

    If the consents of all shareholders entitled to vote have not been 
solicited in writing and if the unanimous written consent of all such 
shareholders has not been received, then the secretary shall give prompt 
notice of the corporate action approved by the shareholders without a 
meeting.  Such notice shall be given to those shareholders entitled to vote 
who have not consented in writing and shall be given in the manner specified 
in Section 2.6 of these bylaws.  In the case of approval of (i) a contract or 
transaction in which a director has a direct or indirect financial interest, 
pursuant to Section 310 of the Code, (ii) indemnification of a corporate 
"agent," pursuant to Section 317 of the Code, (iii) a reorganization of the 
corporation, pursuant to Section 1201 of the Code, and (iv) a distribution in 
dissolution other than in accordance with the rights of outstanding preferred 
shares, pursuant to Section 2007 of the Code, the notice shall be given at 
least ten (10) days before the consummation of any action authorized by that 
approval.

    2.12 RECORD DATE FOR SHAREHOLDER NOTICE; VOTING; GIVING
         CONSENTS

    For purposes of determining the shareholders entitled to notice of any 
meeting or to vote thereat or entitled to give consent to corporate action 
without a meeting, the board of directors may fix, in advance, a record date, 
which shall not be more than sixty (60) days nor less than ten (10) days 
before the date of any such meeting nor more than sixty (60) days before any 
such action without a meeting, and in such event only shareholders of record 
on the date so fixed are entitled to notice and to vote or to give consents, 
as the case may be, notwithstanding any transfer of any shares on the books 
of the corporation after the record date, except as otherwise provided in the 
Code.

    If the board of directors does not so fix a record date:

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

         (b)  the record date for determining shareholders entitled to give 
consent to corporate action in writing without a meeting, (i) when no prior 
action by the board has been taken, shall be the day on which the first 
written consent is given, or (ii) when prior action by the board has been 
taken, shall be at the close of business on the day on which the board adopts 
the resolution relating to that action, or the sixtieth (60th) day before the 
date of such other action, whichever is later.

    The record date for any other purpose shall be as provided in Article 
VIII of these bylaws.

                                     -7-

<PAGE>

    2.13  PROXIES

    Every person entitled to vote for directors, or on any other matter, 
shall have the right to do so either in person or by one or more agents 
authorized by a written proxy signed by the person and filed with the 
secretary of the corporation.  A proxy shall be deemed signed if the 
shareholder's name is placed on the proxy (whether by manual signature, 
typewriting, telegraphic transmission or otherwise) by the shareholder or the 
shareholder's attorney-in-fact.  A validly executed proxy which does not 
state that it is irrevocable shall continue in full force and effect unless 
(i) the person who executed the proxy revokes it prior to the time of voting 
by delivering a writing to the corporation stating that the proxy is revoked 
or by executing a subsequent proxy and presenting it to the meeting or by 
voting in person at the meeting, or (ii) written notice of the death or 
incapacity of the maker of that proxy is received by the corporation before 
the vote pursuant to that proxy is counted; provided, however, that no proxy 
shall be valid after the expiration of eleven (11) months from the date of 
the proxy, unless otherwise provided in the proxy. The dates contained on the 
forms of proxy presumptively determine the order of execution, regardless of 
the postmark dates on the envelopes in which they are mailed.  The 
revocability of a proxy that states on its face that it is irrevocable shall 
be governed by the provisions of Sections 705(e) and 705(f) of the Code.

    2.14  INSPECTORS OF ELECTION

    Before any meeting of shareholders, the board of directors may appoint an 
inspector or inspectors of election to act at the meeting or its adjournment. 
If no inspector of election is so appointed, then the chairman of the meeting 
may, and on the request of any shareholder or a shareholder's proxy shall, 
appoint an inspector or inspectors of election to act at the meeting.  The 
number of inspectors shall be either one (1) or three (3).  If inspectors are 
appointed at a meeting pursuant to the request of one (1) or more 
shareholders or proxies, then the holders of a majority of shares or their 
proxies present at the meeting shall determine whether one (1) or three (3) 
inspectors are to be appointed.  If any person appointed as inspector fails 
to appear or fails or refuses to act, then the chairman of the meeting may, 
and upon the request of any shareholder or a shareholder's proxy shall, 
appoint a person to fill that vacancy.

    Such inspectors shall:

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

         (b)  receive votes, ballots or consents;

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

         (d)  count and tabulate all votes or consents;

                                     -8-

<PAGE>

         (e)  determine when the polls shall close;

         (f)  determine the result; and

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

                                  ARTICLE III

                                   DIRECTORS

    3.1  POWERS

    Subject to the provisions of the Code and any limitations in the articles 
of incorporation and these bylaws relating to action required to be approved 
by the shareholders or by the outstanding shares, the business and affairs of 
the corporation shall be managed and all corporate powers shall be exercised 
by or under the direction of the board of directors.

    3.2  NUMBER OF DIRECTORS

    The number of directors of the corporation shall be not less than six (6) 
nor more than nine (9).  The exact number of directors shall be six (6) 
until changed, within the limits specified above, by a bylaw amending this 
Section 3.2, duly adopted by the board of directors or by the shareholders.  
The indefinite number of directors may be changed, or a definite number may 
be fixed without provision for an indefinite number, by a duly adopted 
amendment to the articles of incorporation or by an amendment to this bylaw 
duly adopted by the vote or written consent of holders of a majority of the 
outstanding shares entitled to vote; provided, however, that an amendment 
reducing the fixed number or the minimum number of directors to a number less 
than five (5) cannot be adopted if the votes cast against its adoption at a 
meeting, or the shares not consenting in the case of an action by written 
consent, are equal to more than sixteen and two-thirds percent (16-2/3%) of 
the outstanding shares entitled to vote thereon.  No amendment may change the 
stated maximum number of authorized directors to a number greater than two 
(2) times the stated minimum number of directors minus one (1).

    3.3  ELECTION QUALIFICATION AND TERM OF OFFICE OF DIRECTORS

    Except as provided in Section 3.4 of these bylaws, at each annual meeting 
of shareholders, directors of the corporation shall be elected to hold office 
until the expiration of the term for which they are elected, and until their 
successors have been duly elected and qualified; except that if any such 
election shall not be so held, such election shall take place at a 
shareholders' meeting called and held in accordance with the Code.  Effective 
upon such time as (i) shares of the capital stock of the corporation are 
designated as qualified for trading as National Market System securities on 
the National Association of Securities Dealers, Inc. Automated Quotation 
System (or any successor

                                     -9-

<PAGE>

national system) ("Qualified Public Offering") and (ii) the corporation has 
at least 800 holders of shares of its capital stock, the directors of the 
corporation shall be divided into two classes as nearly equal in size as is 
practicable, hereby designated Class I and Class II.  The term of office of 
the initial Class I directors shall expire at the next succeeding annual 
meeting of shareholders and the term of office of the initial Class II 
directors shall expire at the second succeeding annual meeting of 
shareholders. For the purposes hereof, the initial Class I and Class II 
directors shall be those directors so designated and elected at the first 
annual meeting of shareholders scheduled to be held after the consummation of 
such a Qualified Public Offering.  At each annual meeting after the annual 
meeting of shareholders scheduled to be held thereafter, directors to replace 
those of a Class office whose terms expire at such annual meeting shall be 
elected to hold office until the second succeeding annual meeting and until 
their respective successors shall have been duly elected and qualified.  If 
the number of directors is hereafter changed, any newly created directorships 
or decrease in directorships shall be so apportioned among the classes as to 
make both classes as nearly equal in number as is practicable.

    Directors need not be shareholders unless so required by the articles of 
incorporation or these bylaws, wherein other qualifications for directors may 
be prescribed.  Election of directors need not be by written ballot.

    3.4  RESIGNATION AND VACANCIES

    Any director may resign effective on giving written notice to the 
chairman of the board, the president, the secretary or the board of 
directors, unless the notice specifies a later time for that resignation to 
become effective.  If the resignation of a director is effective at a future 
time, the board of directors may elect a successor to take office when the 
resignation becomes effective.

    Vacancies in the board of directors may be filled by a majority of the 
remaining directors, even if less than a quorum, or by a sole remaining 
director; however, a vacancy created by the removal of a director by the vote 
or written consent of the shareholders or by court order may be filled only 
by the affirmative vote of a majority of the shares represented and voting at 
a duly held meeting at which a quorum is present (which shares voting 
affirmatively also constitute a majority of the required quorum), or by the 
unanimous written consent of all shares entitled to vote thereon.  Each 
director so elected shall hold office until the next annual meeting of the 
shareholders and until a successor has been elected and qualified.

    A vacancy or vacancies in the board of directors shall be deemed to exist 
(i) in the event of the death, resignation or removal of any director, (ii) 
if the board of directors by resolution declares vacant the office of a 
director who has been declared of unsound mind by an order of court or 
convicted of a felony, (iii) if the authorized number of directors is 
increased, or (iv) if the shareholders fail, at any meeting of shareholders 
at which any director or directors are elected, to elect the number of 
directors to be elected at that meeting.

    The shareholders may elect a director or directors at any time to fill 
any vacancy or vacancies not filled by the directors, but any such election 
other than to fill a vacancy created by removal, if by

                                     -10-

<PAGE>

written consent, shall require the consent of the holders of a majority of 
the outstanding shares entitled to vote thereon.

    3.5  PLACE OF MEETINGS; MEETINGS BY TELEPHONE

    Regular meetings of the board of directors may be held at any place 
within or outside the State of California that has been designated from time 
to time by resolution of the board.  In the absence of such a designation, 
regular meetings shall be held at the principal executive office of the 
corporation.  Special meetings of the board may be held at any place within 
or outside the State of California that has been designated in the notice of 
the meeting or, if not stated in the notice or if there is no notice, at the 
principal executive office of the corporation.

    Any meeting, regular or special, may be held by conference telephone or 
similar communication equipment, so long as all directors participating in 
the meeting can hear one another; and all such directors shall be deemed to 
be present in person at the meeting.

    3.6  REGULAR MEETINGS

    Regular meetings of the board of directors may be held without notice if 
the times of such meetings are fixed by the board of directors.

    3.7  SPECIAL MEETINGS; NOTICE

    Special meetings of the board of directors for any purpose or purposes 
may be called at any time by the chairman of the board, the president, any 
vice president, the secretary or any two directors.

    Notice of the time and place of special meetings shall be delivered 
personally or by telephone to each director or sent by first-class mail or 
telegram, charges prepaid, addressed to each director at that director's 
address as it is shown on the records of the corporation.  If the notice is 
mailed, it shall be deposited in the United States mail at least four (4) 
days before the time of the holding of the meeting.  If the notice is 
delivered personally or by telephone or telegram, it shall be delivered 
personally or by telephone or to the telegraph company at least forty-eight 
(48) hours before the time of the holding of the meeting.  Any oral notice 
given personally or by telephone may be communicated either to the director 
or to a person at the office of the director who the person giving the notice 
has reason to believe will promptly communicate it to the director.  The 
notice need not specify the purpose or the place of the meeting, if the 
meeting is to be held at the principal executive office of the corporation.

    3.8  QUORUM

    A majority of the authorized number of directors shall constitute a 
quorum for the transaction of business, except to adjourn as provided in 
Section 3.10 of these bylaws.  Every act or decision done or made by a 
majority of the directors present at a duly held meeting at which a quorum is 

                                     -11-

<PAGE>

present shall be regarded as the act of the board of directors, subject to

100 or more persons (determined as provided in Section 605 of the Code) on 
the date of approval by the board of directors, and (iii) the approval of the

The board may designate one (1) or more directors as alternate members of any 
committee, who may replace any absent member at any meeting of the committee.

expenses (as defined in Section 317(a) of the Code), judgments, fines, 
settlements and other amounts actually and reasonably incurred in connection 
with any proceeding (as defined in Section 317(a) of the Code), arising by 
reason of the fact that such person is or was an agent of the corporation.  
For purposes of this Section 6, a "director" or "officer" of the corporation 
includes any person (i) who is or was a director or officer of the 
corporation, (ii) who is or was serving at the request of the corporation as 
a director or officer of another corporation, partnership, joint venture, 
trust or other enterprise, or (iii) who was a director or officer of a

     The corporation shall have the power, to the extent and in the manner 
permitted by the Code, to indemnify each of its employees and agents (other 
than directors and officers) against expenses (as defined in Section 317(a) 
of the Code), judgments, fines, settlements, and other amounts actually and 
reasonably incurred in connection with any proceeding (as defined in Section 
317(a) of the Code), arising by reason of the fact that such person is or was 
an agent of the corporation.  For purposes of this Section 6, an "employee" 
or "agent" of the corporation (other than a director or officer) includes any 
person (i) who is or was an employee or agent of the corporation, (ii) who is 
or was serving at the request of the corporation as an employee or agent of 
another corporation, partnership, joint venture, trust or other enterprise, 
or (iii) who was an employee or agent of a corporation which was a 
predecessor corporation of the corporation or of another enterprise at the 
request of such predecessor corporation.

     6.3  PAYMENT OF EXPENSES IN ADVANCE

     Expenses incurred in defending any civil or criminal action or 
proceeding for which indemnification is required pursuant to Section 6.1 or 
for which indemnification is permitted pursuant to Section 6.2 following 
authorization thereof by the Board of Directors shall be paid by the 
corporation in advance of the final disposition of such action or proceeding 
upon receipt of an undertaking by or on behalf of the indemnified party to 
repay such amount if it shall ultimately be determined that the indemnified 
party is not entitled to be indemnified as authorized in this Section 6.

<PAGE>

     6.4      INDEMNITY NOT EXCLUSIVE

     The indemnification provided by this Section 6 shall not be deemed 
exclusive of any other rights to which those seeking indemnification may be 
entitled under any bylaw, agreement, vote of shareholders or disinterested 
directors or otherwise, both as to action in an official capacity and as to 
action in another capacity while holding such office, to the extent that such 
additional rights to indemnification are authorized in the Articles of 
Incorporation.

     6.5  INSURANCE INDEMNIFICATION

     The corporation shall have the power to purchase and maintain insurance 
on behalf of any person who is or was a director, officer, employee or agent 
of the corporation against any liability asserted against or incurred by such 
person in such capacity or arising out of such person's status as such, 
whether or not the corporation would have the power to indemnify him against 
such liability under the provisions of this Section 6.

     6.6  CONFLICTS

     No indemnification or advance shall be made under this Section 6, except 
where such indemnification or advance is mandated by law or the order, 
judgment or decree of any court of competent jurisdiction, in any 
circumstance where it appears:

          (a)    That it would be inconsistent with a provision of the 
Articles of Incorporation, these bylaws, a resolution of the shareholders or 
an agreement in effect at the time of the accrual of the alleged cause of the 
action asserted in the proceeding in which the expenses were incurred or 
other amounts were paid, which prohibits or otherwise limits indemnification; 
or

          (b)  That it would be inconsistent with any condition expressly 
imposed by a court in approving a settlement.

certificate, at any reasonable time during usual business hours, for a 
purpose reasonably related to the holder's interests as a shareholder or as

for the three-month, six-month or nine-month period of the then current

                            ARTICLE VIII

                           GENERAL MATTERS

     8.1  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING

     For purposes of determining the shareholders entitled to receive payment 
of any dividend or other distribution or allotment of any rights or the 
shareholders entitled to exercise any rights in respect of any other lawful 
action (other than action by shareholders by written consent without a 
meeting), the board of directors may fix, in advance, a record date, which 
shall not be more than sixty (60) days before any such action.  In that case, 
only shareholders of record at the close of business on the date so fixed are 
entitled to receive the dividend, distribution or allotment of rights, or to 
exercise such rights, as the case may be, notwithstanding any transfer of any 
shares on the books of the corporation after the record date so fixed, except 
as otherwise provided in the Code.

     If the board of directors does not so fix a record date, then the record 
date for determining shareholders for any such purpose shall be at the close 
of business on the day on which the board adopts the applicable resolution or 
the sixtieth (60th) day before the date of that action, whichever is later.

     8.2  CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS

     From time to time, the board of directors shall determine by resolution

issued in the name of or payable to the corporation, and only the persons so 
authorized shall sign or endorse those instruments.

     8.3  CORPORATE CONTRACTS AND INSTRUMENTS:  HOW EXECUTED

     The board of directors, except as otherwise provided in these bylaws, 
may authorize any officer or officers, or agent or agents, to enter into any 
contract or execute any instrument in the name of and on behalf of the 
corporation; such authority may be general or confined to specific instances. 
Unless so authorized or ratified by the board of directors or within the 
agency power of an officer, no officer, agent or employee shall have any 
power or authority to bind the corporation by any contract or engagement or 
to pledge its credit or to render it liable for any purpose or for any amount.

     8.4  CERTIFICATES FOR SHARES

     A certificate or certificates for shares of the corporation shall be 
issued to each shareholder when any of such shares are fully paid.  The board 
of directors may authorize the issuance of certificates for shares partly 
paid provided that these certificates shall state the total amount of the 
consideration to be paid for them and the amount actually paid.  All 
certificates shall be signed in the name of the corporation by the chairman 
of the board or the vice chairman of the board or the president or a vice 
president and by the chief financial officer or an assistant treasurer or the 
secretary or an assistant secretary, certifying the number of shares and the 
class or series of shares owned by the shareholder.  Any or all of the 
signatures on the certificate may be facsimile.

     In case any officer, transfer agent or registrar who has signed or whose 
facsimile signature has been placed on a certificate ceases to be that 
officer, transfer agent or registrar before that certificate is issued, it 
may be issued by the corporation with the same effect as if that person were 
an officer, transfer agent or registrar at the date of issue.

     8.5  LOST CERTIFICATES

     Except as provided in this Section 8.5, no new certificates for shares 
shall be issued to replace a previously issued certificate unless the latter 
is surrendered to the corporation and cancelled at the same time.  The board 
of directors may, in case any share certificate or certificate for any other 
security is lost, stolen or destroyed, authorize the issuance of replacement 
certificates on such terms and conditions as the board may require; the board 
may require indemnification of the corporation secured by a bond or other 
adequate security sufficient to protect the corporation against any claim 
that may be made against it, including any expense or liability, on account 
of the alleged loss, theft or destruction of the certificate or the issuance 
of the replacement certificate.

     8.6  CONSTRUCTION; DEFINITIONS

     Unless the context requires otherwise, the general provisions, rules of 
construction, and definitions in the Code shall govern the construction of 
these bylaws.  Without limiting the generality of this provision, the 
singular number includes the plural, the plural number includes the singular, 
and the term "person" includes both a corporation and a natural person.

                         LIVINGSTON ENTERPRISES, INC.

                           INDEMNIFICATION AGREEMENT



    This Indemnification Agreement ("Agreement") is effective as of May 9, 
1997 by and between Livingston Enterprises, Inc., a California corporation 
(the "Company"), and             (name) ("Indemnitee").

    WHEREAS, the Company desires to attract and retain the services of highly 
qualified individuals, such as Indemnitee, to serve the Company and its 
related entities;

    WHEREAS, in order to induce Indemnitee to continue to provide services to 
the Company, the Company wishes to provide for the indemnification of, and 
the advancement of expenses to, Indemnitee to the maximum extent permitted by 
California law;

    WHEREAS, the Company and Indemnitee recognize the continued difficulty in 
obtaining liability insurance for the Company's directors, officers, 
employees, agents and fiduciaries, the significant increases in the cost of 
such insurance and the general reductions in the coverage of such insurance;

    WHEREAS, the Company and Indemnitee further recognize the substantial 
increase in corporate litigation in general, subjecting directors, officers, 
employees, agents and fiduciaries to expensive litigation risks at the same 
time as the availability and coverage of liability insurance has been 
severely limited; 

    WHEREAS, the Company and Indemnitee desire to continue to have in place 
the additional protection provided by an indemnification agreement and to 
provide indemnification and advancement of expenses to the Indemnitee to the 
maximum extent permitted by California law; and

    WHEREAS, in view of the considerations set forth above, the Company 
desires that Indemnitee shall be indemnified and advanced expenses by the 
Company as set forth herein;

    NOW, THEREFORE, the Company and Indemnitee hereby agree as set forth 
below.

    1.   CERTAIN DEFINITIONS.

         (a)  "Change in Control" shall mean, and shall be deemed to have 
occurred if, on or after the date of this Agreement, (i) any "person" (as 
such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act 
of 1934, as amended), other than a trustee or other fiduciary holding 
securities under an employee benefit plan of the Company acting in such 
capacity or a corporation owned directly or indirectly by the stockholders of 
the Company in substantially the same proportions

<PAGE>

as their ownership of stock of the Company, becomes the "beneficial owner" 
(as defined in Rule 13d-3 under said Act), directly or indirectly, of 
securities of the Company representing more than 50% of the total voting 
power represented by the Company's then outstanding Voting Securities, (ii) 
during any period of two consecutive years, individuals who at the beginning 
of such period constitute the Board of Directors of the Company and any new 
director whose election by the Board of Directors or nomination for election 
by the Company's stockholders was approved by a vote of at least two thirds 
(2/3) of the directors then still in office who either were directors at the 
beginning of the period or whose election or nomination for election was 
previously so approved, cease for any reason to constitute a majority 
thereof, or (iii) the stockholders of the Company approve a merger or 
consolidation of the Company with any other corporation other than a merger 
or consolidation which would result in the Voting Securities of the Company 
outstanding immediately prior thereto continuing to represent (either by 
remaining outstanding or by being converted into Voting Securities of the 
surviving entity) at least 80% of the total voting power represented by the 
Voting Securities of the Company or such surviving entity outstanding 
immediately after such merger or consolidation, or the stockholders of the 
Company approve a plan of complete liquidation of the Company or an agreement 
for the sale or disposition by the Company of (in one transaction or a series 
of related transactions) all or substantially all of the Company's assets.

         (b)  "Claim" shall mean with respect to a Covered Event:  any 
threatened, pending or completed action, suit, proceeding or alternative 
dispute resolution mechanism, or any hearing, inquiry or investigation that 
Indemnitee in good faith believes might lead to the institution of any such 
action, suit, proceeding or alternative dispute resolution mechanism, whether 
civil, criminal, administrative, investigative or other.

         (c)  References to the "Company" shall include, in addition to 
Corporation, any constituent corporation (including any constituent of a 
constituent) absorbed in a consolidation or merger to which Corporation (or 
any of its wholly owned subsidiaries) is a party which, if its separate 
existence had continued, would have had power and authority to indemnify its 
directors, officers, employees, agents or fiduciaries, so that if Indemnitee 
is or was a director, officer, employee, agent or fiduciary of such 
constituent corporation, or is or was serving at the request of such 
constituent corporation as a director, officer, employee, agent or fiduciary 
of another corporation, partnership, joint venture, employee benefit plan, 
trust or other enterprise, Indemnitee shall stand in the same position under 
the provisions of this Agreement with respect to the resulting or surviving 
corporation as Indemnitee would have with respect to such constituent 
corporation if its separate existence had continued.

         (d)  "Covered Event" shall mean any event or occurrence related to 
the fact that Indemnitee is or was a director, officer, employee, agent or 
fiduciary of the Company, or any subsidiary of the Company, or is or was 
serving at the request of the Company as a director, officer, employee, agent 
or fiduciary of another corporation, partnership, joint venture, trust or 
other enterprise, or by reason of any action or inaction on the part of 
Indemnitee while serving in such capacity.

                                     -2-

<PAGE>

         (e)  "Expenses" shall mean any and all expenses (including 
attorneys' fees and all other costs, expenses and obligations incurred in 
connection with investigating, defending, being a witness in or participating 
in (including on appeal), or preparing to defend, to be a witness in or to 
participate in, any action, suit, proceeding, alternative dispute resolution 
mechanism, hearing, inquiry or investigation), judgments, fines, penalties 
and amounts paid in settlement (if such settlement is approved in advance by 
the Company, which approval shall not be unreasonably withheld), actually and 
reasonably incurred, of any Claim and any federal, state, local or foreign 
taxes imposed on the Indemnitee as a result of the actual or deemed receipt 
of any payments under this Agreement.

         (f)  "Expense Advance" shall mean a payment to Indemnitee pursuant 
to Section 3 of Expenses in advance of the settlement of or final judgement 
in any action, suit, proceeding or alternative dispute resolution mechanism, 
hearing, inquiry or investigation which constitutes a Claim.

         (g)  "Independent Legal Counsel" shall mean an attorney or firm of 
attorneys, selected in accordance with the provisions of Section 2(d) hereof, 
who shall not have otherwise performed services for the Company or Indemnitee 
within the last three years (other than with respect to matters concerning 
the rights of Indemnitee under this Agreement, or of other indemnitees under 
similar indemnity agreements).

         (h)  References to "other enterprises" shall include employee 
benefit plans; references to "fines" shall include any excise taxes assessed 
on Indemnitee with respect to an employee benefit plan; and references to 
"serving at the request of the Company" shall include any service as a 
director, officer, employee, agent or fiduciary of the Company which imposes 
duties on, or involves services by, such director, officer, employee, agent 
or fiduciary with respect to an employee benefit plan, its participants or 
its beneficiaries; and if Indemnitee acted in good faith and in a manner 
Indemnitee reasonably believed to be in the interest of the participants and 
beneficiaries of an employee benefit plan, Indemnitee shall be deemed to have 
acted in a manner "not opposed to the best interests of the Company"  as 
referred to in this Agreement.

         (i)  "Reviewing Party" shall mean, subject to the provisions of 
Section 2(d), any person or body appointed by the Board of Directors in 
accordance with California law to review the Company's obligations hereunder 
and under California law, which may include a member or members of the 
Company's Board of Directors, Independent Legal Counsel or any other person 
or body not a party to the particular Claim for which Indemnitee is seeking 
indemnification.

         (j)  "Section" refers to a section of this Agreement unless 
otherwise indicated.

         (k)  "Voting Securities" shall mean any securities of the Company 
that vote generally in the election of directors.

    2.   INDEMNIFICATION.

                                     -3-

<PAGE>

         (a)  INDEMNIFICATION OF EXPENSES.  Subject to the provisions of 
Section 2(b) below, the Company shall indemnify Indemnitee for Expenses to 
the fullest extent permitted by California law if Indemnitee was or is or 
becomes a party to or witness or other participant in, or is threatened to be 
made a party to or witness or other participant in, any Claim (whether by 
reason of or arising in part out of a Covered Event), including all interest, 
assessments and other charges paid or payable in connection with or in 
respect of such Expenses. 

         (b)  REVIEW OF INDEMNIFICATION OBLIGATIONS.  Notwithstanding the 
foregoing, in the event any Reviewing Party shall have determined (in a 
written opinion, in any case in which Independent Legal Counsel is the 
Reviewing Party) that Indemnitee is not entitled to be indemnified hereunder 
under California law, (i) the Company shall have no further obligation under 
Section 2(a) to make any payments to Indemnitee not made prior to such 
determination by such Reviewing Party, and (ii) the Company shall be entitled 
to be reimbursed by Indemnitee (who hereby agrees to reimburse the Company) 
for all Expenses theretofore paid in indemnifying Indemnitee; PROVIDED, 
HOWEVER, that if Indemnitee has commenced or thereafter commences legal 
proceedings in a court of competent jurisdiction to secure a determination 
that Indemnitee is entitled to be indemnified hereunder under California law, 
any determination made by any Reviewing Party that Indemnitee is not entitled 
to be indemnified hereunder under California law shall not be binding and 
Indemnitee shall not be required to reimburse the Company for any Expenses 
theretofore paid in indemnifying Indemnitee until a final judicial 
determination is made with respect thereto (as to which all rights of appeal 
therefrom have been exhausted or lapsed). Indemnitee's obligation to 
reimburse the Company for any Expenses shall be unsecured and no interest 
shall be charged thereon.  

         (c)  INDEMNITEE RIGHTS ON UNFAVORABLE DETERMINATION; BINDING EFFECT. 
If any Reviewing Party determines that Indemnitee substantively is not 
entitled to be indemnified hereunder in whole or in part under California 
law, Indemnitee shall have the right to commence litigation seeking an 
initial determination by the court or challenging any such determination by 
such Reviewing Party or any aspect thereof, including the legal or factual 
bases therefor, and, subject to the provisions of Section 15, the Company 
hereby consents to service of process and to appear in any such proceeding.  
Absent such litigation, any determination by any Reviewing Party shall be 
conclusive and binding on the Company and Indemnitee.

         (d)  SELECTION OF REVIEWING PARTY; CHANGE IN CONTROL.  If there has 
not been a Change in Control, any Reviewing Party shall be selected by the 
Board of Directors, and if there has been such a Change in Control (other 
than a Change in Control which has been approved by a majority of the 
Company's Board of Directors who were directors immediately prior to such 
Change in Control), any Reviewing Party with respect to all matters 
thereafter arising concerning the rights of Indemnitee to indemnification of 
Expenses under this Agreement or any other agreement or under the Company's 
Articles of Incorporation or Bylaws as now or hereafter in effect, or under 
any other California law, if desired by Indemnitee, shall be Independent 
Legal Counsel selected by Indemnitee and approved by the Company (which 
approval shall not be unreasonably withheld). Such counsel, among other 
things, shall render its written opinion to the Company and Indemnitee as to 
whether and to what extent Indemnitee would be entitled to be indemnified 
hereunder under California law

                                     -4-

<PAGE>

and the Company agrees to abide by such opinion.  The Company agrees to pay 
the reasonable fees of the Independent Legal Counsel referred to above and to 
indemnify fully such counsel against any and all expenses (including 
attorneys' fees), claims, liabilities and damages arising out of or relating 
to this Agreement or its engagement pursuant hereto.  Notwithstanding any 
other provision of this Agreement, the Company shall not be required to pay 
Expenses of more than one Independent Legal Counsel in connection with all 
matters concerning a single Indemnitee, and such Independent Legal Counsel 
shall be the Independent Legal Counsel for any or all other Indemnitees 
unless (i) the Company otherwise determines or (ii) any Indemnitee shall 
provide a written statement setting forth in detail a reasonable objection to 
such Independent Legal Counsel representing other Indemnitees.

         (e)  MANDATORY PAYMENT OF EXPENSES.  Notwithstanding any other 
provision of this Agreement other than Section 10 hereof, to the extent that 
Indemnitee has been successful on the merits or otherwise, including, without 
limitation, the dismissal of an action without prejudice, in defense of any 
Claim, Indemnitee shall be indemnified against all Expenses incurred by 
Indemnitee in connection therewith.

    3.   EXPENSE ADVANCES.

         (a)  OBLIGATION TO MAKE EXPENSE ADVANCES.  Upon receipt of a written 
undertaking by or on behalf of the Indemnitee to repay such amounts if it 
shall ultimately be determined that the Indemnitee is not entitled to be 
indemnified therefor by the Company, the Company shall make Expense Advances 
to Indemnitee.

         (b)  FORM OF UNDERTAKING.  Any written undertaking by the Indemnitee 
to repay any Expense Advances hereunder shall be unsecured and no interest 
shall be charged thereon.

         (c)  DETERMINATION OF REASONABLE EXPENSE ADVANCES.  The parties 
agree that for the purposes of any Expense Advance for which Indemnitee has 
made written demand to the Company in accordance with this Agreement, all 
Expenses included in such Expense Advance that are certified by affidavit of 
Indemnitee's counsel as being reasonable shall be presumed conclusively to be 
reasonable.

    4.   PROCEDURES FOR INDEMNIFICATION AND EXPENSE ADVANCES.

         (a)  TIMING OF PAYMENTS.  All payments of Expenses (including 
without limitation Expense Advances) by the Company to the Indemnitee 
pursuant to this Agreement shall be made to the fullest extent permitted by 
California law as soon as practicable after written demand by Indemnitee 
therefor is presented to the Company, but in no event later than forty-five 
(45) business days after such written demand by Indemnitee is presented to 
the Company, except in the case of Expense Advances, which shall be made no 
later than twenty (20) business days after such written demand by Indemnitee 
is presented to the Company.

                                     -5-

<PAGE>

         (b)  NOTICE/COOPERATION BY INDEMNITEE.  Indemnitee shall, as a 
condition precedent to Indemnitee's right to be indemnified or Indemnitee's 
right to receive Expense Advances under this Agreement, give the Company 
notice in writing as soon as practicable of any Claim made against Indemnitee 
for which indemnification will or could be sought under this Agreement.  
Notice to the Company shall be directed to the Chief Executive Officer of the 
Company at the address shown on the signature page of this Agreement (or such 
other address as the Company shall designate in writing to Indemnitee).  In 
addition, Indemnitee shall give the Company such information and cooperation 
as it may reasonably require and as shall be within Indemnitee's power.

         (c)  NO PRESUMPTIONS; BURDEN OF PROOF.  For purposes of this 
Agreement, the termination of any Claim by judgment, order, settlement 
(whether with or without court approval) or conviction, or upon a plea of 
NOLO CONTENDERE, or its equivalent, shall not create a presumption that 
Indemnitee did not meet any particular standard of conduct or have any 
particular belief or that a court has determined that indemnification is not 
permitted by this Agreement or California law.  In addition, neither the 
failure of any Reviewing Party to have made a determination as to whether 
Indemnitee has met any particular standard of conduct or had any particular 
belief, nor an actual determination by any Reviewing Party that Indemnitee 
has not met such standard of conduct or did not have such belief, prior to 
the commencement of legal proceedings by Indemnitee to secure a judicial 
determination that Indemnitee should be indemnified under this Agreement or 
California law, shall be a defense to Indemnitee's claim or create a 
presumption that Indemnitee has not met any particular standard of conduct or 
did not have any particular belief.  In connection with any determination by 
any Reviewing Party or otherwise as to whether the Indemnitee is entitled to 
be indemnified hereunder, the burden of proof shall be on the Company to 
establish that Indemnitee is not so entitled.

         (d)  NOTICE TO INSURERS.  If, at the time of the receipt by the 
Company of a notice of a Claim pursuant to Section 4(b) hereof, the Company 
has liability insurance in effect which may cover such Claim, the Company 
shall give prompt notice of the commencement of such Claim to the insurers in 
accordance with the procedures set forth in the respective policies.  The 
Company shall thereafter take all necessary or desirable action to cause such 
insurers to pay, on behalf of the Indemnitee, all amounts payable as a result 
of such Claim in accordance with the terms of such policies.

         (e)  SELECTION OF COUNSEL.  In the event the Company shall be 
obligated hereunder to provide indemnification for or make any Expense 
Advances with respect to the Expenses of any Claim, the Company, if 
appropriate, shall be entitled to assume the defense of such Claim with 
counsel approved by Indemnitee (which approval shall not be unreasonably 
withheld) upon the delivery to Indemnitee of written notice of the Company's 
election to do so.  After delivery of such notice, approval of such counsel 
by Indemnitee and the retention of such counsel by the Company, the Company 
will not be liable to Indemnitee under this Agreement for any fees or 
expenses of separate counsel subsequently employed by or on behalf of 
Indemnitee with respect to the same Claim; provided that, (i) Indemnitee 
shall have the right to employ Indemnitee's separate counsel in any such 
Claim at Indemnitee's expense and (ii) if (A) the employment of separate 
counsel by Indemnitee has

                                     -6-

<PAGE>

been previously authorized by the Company, (B) Indemnitee shall have 
reasonably concluded that there may be a conflict of interest between the 
Company and Indemnitee in the conduct of any such defense, or (C) the Company 
shall not continue to retain such counsel to defend such Claim, then the fees 
and expenses of Indemnitee's separate counsel shall be Expenses for which 
Indemnitee may receive indemnification or Expense Advances hereunder.

    5.   ADDITIONAL INDEMNIFICATION RIGHTS; NONEXCLUSIVITY.

         (a)  SCOPE.  The Company hereby agrees to indemnify the Indemnitee 
to the fullest extent permitted by California law, notwithstanding that such 
indemnification is not specifically authorized by the other provisions of 
this Agreement, the Company's Articles of Incorporation, the Company's Bylaws 
or by statute.  In the event of any change after the date of this Agreement 
in any California law, statute or rule which expands the right of a 
California corporation to indemnify a member of its board of directors or an 
officer, employee, agent or fiduciary, it is the intent of the parties hereto 
that Indemnitee shall enjoy by this Agreement the greater benefits afforded 
by such change.  In the event of any change in any California law, statute or 
rule which narrows the right of a California corporation to indemnify a 
member of its board of directors or an officer, employee, agent or fiduciary, 
such change, to the extent not otherwise required by such law, statute or 
rule to be applied to this Agreement, shall have no effect on this Agreement 
or the parties' rights and obligations hereunder except as set forth in 
Section 10(a) hereof.

         (b)  NONEXCLUSIVITY.  The indemnification and the payment of Expense 
Advances provided by this Agreement shall be in addition to any rights to 
which Indemnitee may be entitled under the Company's Articles of 
Incorporation, its Bylaws, any other agreement, any vote of stockholders or 
disinterested directors, the General Corporation Law of the State of 
California, or otherwise. The indemnification and the payment of Expense 
Advances provided under this Agreement shall continue as to Indemnitee for 
any action taken or not taken while serving in an indemnified capacity even 
though subsequent thereto Indemnitee may have ceased to serve in such 
capacity.

    6.   NO DUPLICATION OF PAYMENTS.  The Company shall not be liable under 
this Agreement to make any payment in connection with any Claim made against 
Indemnitee to the extent Indemnitee has otherwise actually received payment 
(under any insurance policy, provision of the Company's Articles of 
Incorporation, Bylaws or otherwise) of the amounts otherwise payable 
hereunder.

    7.   PARTIAL INDEMNIFICATION.  If Indemnitee is entitled under any 
provision of this Agreement to indemnification by the Company for some or a 
portion of Expenses incurred in connection with any Claim, but not, however, 
for all of the total amount thereof, the Company shall nevertheless indemnify 
Indemnitee for the portion of such Expenses to which Indemnitee is entitled.

    8.   MUTUAL ACKNOWLEDGEMENT.  Both the Company and Indemnitee acknowledge 
that in certain instances, federal law or applicable public policy may 
prohibit the Company from indemnifying its directors, officers, employees, 
agents or fiduciaries under this Agreement or otherwise.

                                     -7-

<PAGE>

Indemnitee understands and acknowledges that the Company has undertaken or 
may be required in the future to undertake with the Securities and Exchange 
Commission to submit the question of indemnification to a court in certain 
circumstances for a determination of the Company's right under public policy 
to indemnify Indemnitee.

    9.   LIABILITY INSURANCE.  To the extent the Company maintains liability 
insurance applicable to directors, officers, employees, agents or 
fiduciaries, Indemnitee shall be covered by such policies in such a manner as 
to provide Indemnitee the same rights and benefits as are provided to the 
most favorably insured of the Company's directors, if Indemnitee is a 
director; or of the Company's officers, if Indemnitee is not a director of 
the Company but is an officer; or of the Company's key employees, agents or 
fiduciaries, if Indemnitee is not an officer or director but is a key 
employee, agent or fiduciary.

    10.  EXCEPTIONS.  Notwithstanding any other provision of this Agreement, 
the Company shall not be obligated pursuant to the terms of this Agreement:

         (a)  EXCLUDED ACTION OR OMISSIONS.  To indemnify Indemnitee for 
Expenses resulting from acts, omissions or transactions for which Indemnitee 
is prohibited from receiving indemnification under this Agreement or 
California law; PROVIDED, HOWEVER, that notwithstanding any limitation set 
forth in this Section 10(a) regarding the Company's obligation to provide 
indemnification, Indemnitee shall be entitled under Section 3 to receive 
Expense Advances hereunder with respect to any such Claim unless and until a 
court having jurisdiction over the Claim shall have made a final judicial 
determination (as to which all rights of appeal therefrom have been exhausted 
or lapsed) that Indemnitee has engaged in acts, omissions or transactions for 
which Indemnitee is prohibited from receiving indemnification under this 
Agreement or California law.

         (b)  CLAIMS INITIATED BY INDEMNITEE.  To indemnify or make Expense 
Advances to Indemnitee with respect to Claims initiated or brought 
voluntarily by Indemnitee and not by way of defense, counterclaim or 
crossclaim, except (i) with respect to actions or proceedings brought to 
establish or enforce a right to indemnification under this Agreement or any 
other agreement or insurance policy or under the Company's Articles of 
Incorporation or Bylaws now or hereafter in effect relating to Claims for 
Covered Events, (ii) in specific cases if the Board of Directors has approved 
the initiation or bringing of such Claim, or (iii) as otherwise required 
under Section 317 of the California General Corporation Law, regardless of 
whether Indemnitee ultimately is determined to be entitled to such 
indemnification or insurance recovery, as the case may be.

         (c)  LACK OF GOOD FAITH.  To indemnify Indemnitee for any Expenses 
incurred by the Indemnitee with respect to any action instituted (i) by 
Indemnitee to enforce or interpret this Agreement, if a court having 
jurisdiction over such action determines as provided in Section 13 that each 
of the material assertions made by the Indemnitee as a basis for such action 
was not made in good faith or was frivolous, or (ii) by or in the name of the 
Company to enforce or interpret this Agreement, if a court having 
jurisdiction over such action determines as provided in Section 13 that

                                     -8-

<PAGE>


each of the material defenses asserted by Indemnitee in such action was made 
in bad faith or was frivolous.

         (d)  CLAIMS UNDER SECTION 16(B).  To indemnify Indemnitee for 
expenses and the payment of profits arising from the purchase and sale by 
Indemnitee of securities in violation of Section 16(b) of the Securities 
Exchange Act of 1934, as amended, or any similar successor statute; PROVIDED, 
HOWEVER, that notwithstanding any limitation set forth in this Section 10(d) 
regarding the Company's obligation to provide indemnification, Indemnitee 
shall be entitled under Section 3 to receive Expense Advances hereunder with 
respect to any such Claim unless and until a court having jurisdiction over 
the Claim shall have made a final judicial determination (as to which all 
rights of appeal therefrom have been exhausted or lapsed) that Indemnitee has 
violated said statute.

    11.  COUNTERPARTS.  This Agreement may be executed in one or more 
counterparts, each of which shall constitute an original.

    12.  BINDING EFFECT; SUCCESSORS AND ASSIGNS.  This Agreement shall be 
binding upon and inure to the benefit of and be enforceable by the parties 
hereto and their respective successors, assigns (including any direct or 
indirect successor by purchase, merger, consolidation or otherwise to all or 
substantially all of the business or assets of the Company), spouses, heirs 
and personal and legal representatives.  The Company shall require and cause 
any successor (whether direct or indirect, and whether by purchase, merger, 
consolidation or otherwise) to all, substantially all, or a substantial part, 
of the business or assets of the Company, by written agreement in form and 
substance satisfactory to Indemnitee, expressly to assume and agree to 
perform this Agreement in the same manner and to the same extent that the 
Company would be required to perform if no such succession had taken place.  
This Agreement shall continue in effect regardless of whether Indemnitee 
continues to serve as a director, officer, employee, agent or fiduciary (as 
applicable) of the Company or of any other enterprise at the Company's 
request.

Indemnitee shall be entitled to be indemnified for all Expenses incurred by 
Indemnitee with respect to such action (including without limitation 
attorneys' fees), regardless of whether Indemnitee is ultimately successful 
in such action, unless as a part of such action a court having jurisdiction

which all rights of appeal therefrom have been exhausted or lapsed) that each 
of the material defenses asserted by Indemnitee in such action was made in 
bad faith or was frivolous; provided, however, that until such final judicial 
determination is made, Indemnitee shall be entitled under Section 3 to 
receive payment of Expense Advances hereunder with respect to such action.

    14.  NOTICE.  All notices, requests, demands and other communications

liabilities, powers and duties of the parties to this Agreement, shall be

                          LIVINGSTON ENTERPRISES, INC.
                             1994 STOCK OPTION PLAN

     I.  PURPOSES OF THE PLAN

         This 1994 Stock Option Plan is intended to promote the interests and 
success of Livingston Enterprises, Inc., a California corporation, by 
providing a method whereby eligible individuals who provide valuable services 
to the Company are offered incentives which will enable and encourage them to 
acquire a proprietary interest, or otherwise increase their proprietary 
interest, in the Company.

    II.  DEFINITIONS

         For the purposes of this Plan, the following definitions shall apply:

         A.  BOARD shall mean the Company's board of directors.

         B.  CODE shall mean the Internal Revenue Code of 1986, as amended.

         C.  COMMITTEE shall mean a committee of two (2) or more Board 
members appointed by the Board to exercise one or more administrative 
functions under the Plan.

         D.  COMMON STOCK shall mean shares of the Company's common stock.

corporation, or any "Parent" or "Subsidiary" as defined in this Article II.

         F.  CORPORATE TRANSACTION shall mean either of the following 
Shareholder-approved transactions to which the Company is a party:

             (i)   a merger or consolidation in which securities possessing 
      more than eighty percent (80%) of the total combined voting power of 
      the Company's outstanding securities are transferred to a person or 
      persons different from those who held those securities immediately 
      prior to such transaction, or

          (ii)  the sale, transfer or other disposition of all or 
      substantially all of the Company's assets in complete liquidation or 
      dissolution of the Company.

         G.  EMPLOYEE shall mean an individual who is in the employ of the 
Company, subject to the control and direction of the Company as to both the 
work to be performed and the manner and method of performance. The payment of 
a director's fee by the Company shall not be sufficient to classify a 
Director as an "Employee."

<PAGE>

             (i)   If the Common Stock is listed or admitted to trading on 
      any Stock Exchange, or on the NASDAQ National Market System, then 
      the Fair Market Value shall be the closing selling price per share 
      of Common Stock on the date in question on the Stock Exchange 
      determined by the Board to be the primary market for the Common 
      Stock, as such price is officially quoted in the composite tape of 
      transactions on such exchange, or as reported by the National 
      Association of Securities Dealers through the NASDAQ National Market 
      System. If there is no closing selling price for the Common Stock on 
      the date in question, then the Fair Market Value shall be the 
      closing selling price on the preceding date for which such quotation 
      exists.

          (ii)  If the Common Stock is at the time neither listed nor 
      admitted to trading on any Stock Exchange nor traded on the NASDAQ 
      National Market System, then such Fair Market Value shall be 
      determined in good faith by the Board after taking into account such 
      factors as it deems appropriate.

         J.  INCENTIVE OPTION shall mean an Option which satisfies the 
requirements of Code Section 422.

Board or a consultant or independent contractor.

         Q.  STOCK EXCHANGE shall mean either the American Stock Exchange or 
the New York Stock Exchange.

         R.  SUBSIDIARY shall mean a "subsidiary corporation," whether now or 
hereafter existing, as defined in Section 424(f) of the Code.

         S.  10% SHAREHOLDER shall mean the owner of stock (as determined 
under Code Section 424(d)) possessing ten percent (10%) or more of the total 
combined voting power of all classes of stock of the company.

   III.  ADMINISTRATION OF THE PLAN

         A.  The Plan is administered by the Board. Any or all administrative 
functions otherwise exercisable by the Board may, however, be delegated to a 
Committee. Members of such Committee shall serve for such period of time as 
the Board may determine and shall be subject to removal by the Board at any 
time. The Board may also at any time terminate the functions of the Committee 
and reassume all powers and authority previously delegated.

                                       2
<PAGE>

         B.  The Board shall have full power and authority (subject to the 
limitations herein) to establish such rules and regulations as it may deem 
appropriate for proper administration of the Plan, and to make such 
determinations and interpretations in connection with the Plan and any 
outstanding Options, as it may deem necessary or advisable. Decisions of the 
Board are final and binding on all parties who have an interest in the Plan 
or any outstanding Option.

    IV.  ELIGIBILITY FOR OPTION GRANTS

         A.  The persons eligible to receive Option grants under the Plan are 
as follows:

             (i)    Employees;

             (ii)   non-employee members of the Board;

             (iii)  consultants and other independent contractors.

         B.  The Board shall have full authority to determine which eligible 
individuals are to receive Option grants under the Plan, the number of shares 
to be covered by each grant, the status of the granted Option as either an 
Incentive Option or a Non-Statutory Option, the time or times at which each 
Option is to become exercisable, the vesting schedule (if any) applicable to 
the Option shares, the form of stock option agreement utilized under the Plan 
and the maximum term for which the Option is to remain outstanding.

     V.  STOCK SUBJECT TO THE PLAN

         A.  The stock issuable under the Plan shall be shares of the 
Company's authorized but unissued or re-acquired Common Stock. The maximum 
number of shares which may be issued over the term of the Plan shall not 
exceed 1,000,000 shares, subject to adjustment from time to time in 
accordance with the provisions of this Article V.

         B.  Shares subject to outstanding Options shall be available for 
subsequent Option grants under the Plan to the extent (i) the Options expire 
or terminate for any reason prior to exercise in full or (ii) the Options 
are cancelled in accordance with the cancellation-regrant provisions of 
Article IX of this Plan. All shares issued under this Plan shall reduce on a 
share-for-share basis the number of shares of Common Stock available for 
subsequent Option grants.

         C.  In the event any change is made to the Common Stock issuable 
under the Plan by reason of any stock split, stock dividend, 
recapitalization, combination of shares, exchange of shares or other change 
affecting the outstanding Common Stock as a class, without the Company's 
receipt of consideration, appropriate adjustments shall be made to (i) the 
maximum number and/or class of securities issuable under the Plan and 
(ii) the number and/or class of securities and the exercise price per share 
in effect under each outstanding Option, in order to prevent the dilution or 
enlargement of benefits hereunder. Any such adjustments determined by the 
Board will be final, binding and conclusive.

    VI.  TERMS AND CONDITIONS OF OPTIONS

         Options granted pursuant to the Plan shall be authorized by action 
of the Board and may, at the Board's discretion, be either Incentive Options 
or Non-Statutory Options. Each granted Option shall be evidenced by a stock 
option agreement in the form approved by the Board, provided however, that 
each such stock option agreement shall comply with the terms and conditions 
specified below. Each stock option agreement evidencing an Incentive Option 
shall, in addition, be subject to the applicable provisions of Article VII.

                                       3
<PAGE>

         A.  EXERCISE PRICE

             1.  The exercise price per share shall be fixed by the Board. In 
no event, however, shall the exercise price per share be less than 
eighty-five percent (85%) of the Fair Market Value per share of Common Stock 
on the date of the Option grant.

             2.  If the individual to whom the Option is granted is a 10% 
Shareholder, then the exercise price per share shall not be less than one 
hundred ten percent (110%) of the Fair Market Value per share of Common Stock 
on the grant date.

             3.  The exercise price shall become immediately due upon 
exercise of the Option and shall, subject to the provisions of Article X and 
the agreement evidencing the grant, be payable in cash or check made payable 
to the Company.

         B.  TERM AND EXERCISE OF OPTIONS  Each Option granted under the Plan 
shall be exercisable, upon written notice, at such time or times, during such 
period and for such number of shares as shall be determined by the Board and 
set forth in the stock option agreement. However, no Option shall have a term 
in excess of ten (10) years measured from the grant date. The Option shall be 
exercisable during the Optionee's lifetime only by the Optionee and shall not 
be assignable or transferable other than by will or by the laws of descent 
and distribution following Optionee's death.

         C.  EFFECT OF TERMINATION OF SERVICE

             1.  Except to the extent otherwise provided pursuant to 
subsection C.2 below, the following provisions shall govern the exercise 
period applicable to any Options held by the Optionee at the time of 
cessation of Service, disability or death:

                 (a)  Should the Optionee cease to remain in Service for any 
         reason other than death or disability, then the period during which 
         each outstanding Option held by such Optionee is to remain 
         exercisable shall be limited to the thirty (30) day period following 
         the date of cessation of Service.

                 (b)  Should such Service terminate by reason of disability, 
         then the period during which each outstanding Option held by the 
         Optionee is to remain exercisable shall be limited to the six (6) 
         month period following the date of such cessation of Service.

                 (c)  Should the Optionee die while holding on or more 
         outstanding Options, then the period during which each such Option 
         is to remain exercisable shall be limited to the twelve (12) month 
         period following the date of the Optionee's death. During such 
         period, the Option may be exercised by the personal representative 
         of the Optionee's estate or by the person or persons to whom the 
         option is transferred pursuant to Optionee's will or in accordance 
         with the laws of descent and distribution.

                 (d)  Under no circumstances, however, shall any such Option be 
         exercisable after the specified expiration date of the Option term.

                 (e)  During the applicable post-Service exercise period, the 
         Option may not be exercised in the aggregate for more than the 
         number of vested shares for which the Option is exercisable on the 
         date of the Optionee's cessation of Service. Upon the expiration of 
         the applicable exercise period or (if earlier) upon the expiration 
         of the Option term, the Option shall

                                       4
<PAGE>

         terminate and cease to be exercisable for any vested shares for 
         which the Option has not been exercised. The Option shall, however, 
         immediately upon the Optionee's cessation of Service, terminate and 
         cease to be outstanding with respect to any Option shares for which 
         the Option is not at that time exercisable or in which the Optionee 
         is not otherwise at that time vested.

             2.  The Board shall have full power and authority to extend the 
period of time for which the Option is to remain exercisable following the 
Optionee's cessation of Service, disability or death from the limited period 
in effect under subsection C.1 of this Article VI to such greater period of 
time as the Board shall deem appropriate; provided, that in no event shall 
such Option be exercisable after the specified expiration date of the Option 
term.

         D.  SHAREHOLDER RIGHTS  Shareholder rights are only acquired only by 
an Optionee upon Optionee's exercise of the Option.

         E.  RULE 16b-3  Options granted to persons subject to Section 16(b) 
of the Securities Exchange Act of 1934, as amended, must comply with 
Rule 16b-3 and shall contain such additional conditions or restrictions as 
may be required thereunder to qualify for the maximum exemption from 
Section 16 with respect to Plan transactions.

   VII.  INCENTIVE OPTIONS

         The terms and conditions specified below are applicable to all 
Incentive Options granted under the Plan. Except as modified by the 
provisions of this Article VII, all other provisions of the Plan are also 
applicable to Incentive Options. Incentive Options may only be granted to 
individuals who are Employees. Options which are specifically designated as 
Non-Statutory shall not be subject to these terms and conditions.

         A.  EXERCISE PRICE  The exercise price per share of the Common Stock 
subject to an Incentive Option shall in no event be less than one hundred 
percent (100%) of Fair Market Value on the date of grant.

         B.  DOLLAR LIMITATION  The aggregate Fair Market Value of the Common 
Stock (determined as of the respective date of grant) for which one (1) or 
more Options granted to any Employee under this Plan may for the first time 
become exercisable as Incentive Options during any one (1) calendar year 
shall not exceed the sum of One Hundred Thousand Dollars ($100,000). 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 Options as Incentive Options shall 
be applied on the basis of the order in which such Options are granted. 
Should the applicable One Hundred Thousand Dollar ($100,000) limitation in 
fact be exceeded in any calendar year, then the Option shall nevertheless 
become exercisable for the excess number of shares in such calendar year as a 
Non-Statutory Option.

         C.  10% SHAREHOLDER.  If any individual to whom an Incentive Option 
is granted is a 10% Shareholder, then the Option term shall not exceed five 
(5) years measured from the grant date.


  VIII.  CORPORATE TRANSACTIONS

         A.  Upon the completion of a Corporate Transaction, each outstanding 
Option granted under this Plan shall immediately terminate and cease to be 
exercisable; except in the event, and to the extent, assumed by a successor 
corporation (or other entity).

                                       5
<PAGE>

         B.  If the Plan (and all unexercised Options) terminates as a result 
of a Corporate Transaction, all Optionees entitled to exercise any vested but 
unexercised portions of Options then outstanding shall have the right, at 
such time prior to the consummation or closing of the Corporate Transaction, 
to exercise the vested but unexercised portions of their Options.

         C.  The Board and the board of directors of an assuming corporation 
(or other entity) may decide it to be in the best interests of the parties 
to have the Plan and all outstanding Options either: (1) continue, and 
assume Options heretofore granted in accordance with the terms herein or, 
(2) substitute the outstanding Options, with appropriate adjustments as to 
the number and type of shares and exercise prices, with Options for the stock 
of the successor.

    IX.  CANCELLATION AND REGRANT OF OPTIONS

         The Board shall have the authority to effect, at any time, with the 
consent of the affected Optionees, the cancellation of any or all outstanding 
Options under the Plan and to grant in substitution therefore new Options 
under the Plan, covering the same or different numbers of shares of Common 
Stock, but with an exercise price per share not less than (i) one hundred 
percent (100%) of the Fair Market Value per share of Common Stock on the new 
grant date in the case of a grant of an Incentive Option; (ii) one hundred 
ten percent (110%) of such Fair Market Value in the case of an Option grant 
to a 10% Shareholder; or (iii) eighty-five percent (85%) of such Fair Market 
Value in the case of all other grants.

     X.  LOANS

         A.  The Board may assist any Optionee in the exercise of one or more 
Options granted to the Optionee by:

             (i)   authorizing the extension of a loan from the Company to 
         the Optionee, or

             (ii)  permitting the Optionee to pay the exercise price in 
         installments over a period of time.

         B.  The terms of any loan or installment payment (including the 
interest rate and terms of repayment) shall be established by the Board in 
its sole discretion. Loans or installment payments may be authorized with or 
without security or collateral. Any loan made to a consultant or other 
non-employee advisor, however, must be secured by property other than the 
purchased shares of Common Stock. In all events, the maximum credit available 
to each Optionee may not exceed the sum of (i) the aggregate exercise price 
payable for the purchased shares plus (ii) any Federal, state and local 
income and employment tax liability incurred by the Optionee in connection 
with such exercise.

    XI.  NO EMPLOYMENT OR SERVICE RIGHTS

         Nothing in the Plan shall confer upon the Optionee any right to 
continue in Service or remain an Employee for any period of specific 
duration, or interfere with or otherwise restrict in any way the rights of 
the Company or of the Optionee, which rights are hereby expressly reserved by 
each, to terminate the Optionee's Service at any time for any reason, with or 
without cause.

   XII.  TERMINATION AND AMENDMENT OF THE PLAN

         A.  The Board shall have complete and exclusive power and authority 
to terminate, suspend, amend or modify the Plan in any or all respects 
whatsoever. No such termination, amendment or modification shall, however, 
without the consent of the Optionee's,

                                       6
<PAGE>

adversely affect their rights and obligations under their outstanding 
Options. In addition, the Board shall not, without the approval of the 
Company's shareholders, (i) increase the maximum number of shares issuable 
under the Plan, except for permissible adjustments under Article V; (ii) 
materially modify the eligibility requirements for Option grants; or (iii) 
otherwise materially increase the benefits accruing to Option holders.

     B.  Options may be granted under this Plan to purchase shares of Common 
Stock in excess of the number of shares then available for issuance under the 
Plan, provided an amendment sufficiently increasing the number of shares of 
Common Stock available for issuance under the Plan is approved by the 
Company's shareholders within twelve (12) months after the date the excess 
grants are first made.

  XIII.  EFFECTIVE DATE AND TERM OF PLAN

     A.  The Plan shall become effective when adopted by the Board, but no 
Option granted under the Plan shall become exercisable unless and until the 
Plan shall have been approved by the Company's shareholders. If such 
shareholder approval is not obtained within twelve (12) months after the date 
of the Board's adoption of the Plan, then all Options previously granted 
under the Plan shall terminate and no further Options shall be granted. 
Subject to this limitation, the Board may grant Options under the Plan at any 
time after the effective date and before the date fixed herein for 
termination of the Plan.

     B.  Unless sooner terminated in accordance with Articles VIII and/or 
XII, the Plan shall terminate upon the earlier of (i) the expiration of the 
ten (10) year period measured from the date the Plan is adopted by the 
Board; or (ii) the date on which all shares available for issuance under the 
Plan shall have been issued pursuant to the exercise of Options granted under 
the Plan.

  XIV.  USE OF PROCEEDS

     Any cash proceeds received by the Company from the sale of shares 
pursuant to Options granted under the Plan will be used for general corporate 
purposes.

  XV.  TAX ISSUES

     The Company makes no representations or warranties to Optionee 
concerning the Federal and/or state tax consequences of the exercise of an 
Option granted to Optionee, or the ultimate disposition of the Common Stock 
issued thereunder. Optionee understands that the applicable tax laws and 
regulations are subject to change, and it is Optionee's sole responsibility 
to consult a tax adviser before exercising an Option or disposing any Common

XVIII.  CONDITIONS UPON ISSUANCE OF SHARES

     A.  Shares of Common Stock will not be issued pursuant to the exercise 
of an Option unless the exercise of such Option and the issuance and delivery 
of such shares pursuant thereto comply with all relevant provisions of law, 
including, without limitation, the Securities Act of 1933, as amended, the 
Securities Exchange Act of 1934, as amended, the rules and regulations 
promulgated thereunder, and the requirements of any Stock Exchange, upon 
which the shares may then be listed, and shall be further subject to the 
approval of counsel for the Company with respect to such compliance.

     B.  As a condition to the exercise of an Option, the Company may require 
the person exercising such Option to represent and warrant at the time of any 
such exercise that the shares are being purchased only for investment and 
without any present intention to sell or distribute such shares if, in the 
opinion of counsel for the Company, such a representation is required by any 
of the aforementioned relevant provisions of law.

     C.  If the Employment of an Optionee is terminated for any reason (other 
than death, Permanent Disability or retirement in accordance with Company 
policy), the Company shall have the option, for a term of sixty (60) days 
after the expiration of the thirty (30) day exercise term following cessation 
of Optionee's Service (set forth in Article VI C.1(a) herein), to purchase 
for cash, or cancellation of indebtedness, all or any part of the Optionee's 
Common Stock issued pursuant to this Plan. The repurchase price to the 
Company shall be the higher of the exercise price or the Fair Market Value of 
the Common Stock as of the date of termination of employment. The Company 
repurchase rights set forth herein will not apply, and this paragraph will 
become void, upon the Company's securities becoming publicly traded.

                       INVESTMENT REPRESENTATION STATEMENT

OPTIONEE       :

COMPANY        :    LIVINGSTON ENTERPRISES, INC.

SECURITY       :    COMMON STOCK (the "Shares")

NO. OF SHARES  :

In connection with the purchase of the above-listed Common Stock, the
undersigned Optionee represents to the Company the following:


          (a)  Optionee is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Shares. Optionee is acquiring
the Shares for investment for Optionee's own account only and not with the view
to, or for resale in connection with, any "distribution" thereof within the
meaning of the Securities Act of 1933, as amended (the "Securities Act").

          (b)  Optionee understands that the Shares have not been registered
under the Securities Act, that no market presently exists for the Shares, and
that the Shares may not be sold or transferred unless and until registered
under the Securities Act or unless, in the opinion of counsel, such transfer is
exempt from the registration requirements of the Securities Act. Optionee
further understands that it is unlawful to consummate a sale or transfer of this
security, or any interest therein, or to receive any consideration therefor,
without the prior written consent of the Commissioner of Corporations of the
State of California, except as permitted in the Commissioner's Rules (Section
260.141.11, Title 10, California Administrative Code), a copy of which will be
provided to Optionee together with Optionee's stock certificate representing the
Shares purchased.

          (c)  Optionee acknowledges and understands that the Shares constitute
"restricted securities" under the Securities Act and have been issued in
reliance upon a specific exemption therefrom, which exemption depends upon,
among other things, the bona fide nature of Optionee's investment intent as
expressed herein. Optionee further understands that the Shares must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available. Optionee further acknowledges
and understands that the Company is under no obligation to register the Shares.

          (d)  Optionee is familiar with the provisions of Rule 701 and Rule 
144, each promulgated under the Securities Act, which, in substance, permit 
limited public resale of "restricted securities" acquired, directly or 
indirectly from the issuer thereof, in a non-public offering subject to the 
satisfaction of certain conditions. Rule 701 provides that if the issuer 
qualifies under Rule 701 at the time of exercise of the Option by the 
Optionee, such exercise will be exempt from registration under the Securities 
Act. In the event the Company later becomes subject to the reporting 
requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934, 
as amended (the "Exchange Act"), ninety (90) days thereafter securities 
exempt under Rule 701 may be resold, subject to the satisfaction of certain 
of the conditions specified by Rule 144, including among other things: (1) 
the sale being made through a broker in an unsolicited "broker's transaction" 
or in transactions directly with a "market maker" (as these terms are defined 
under the Exchange Act) and, in the case of an affiliate, (2) the 
availability of certain public information about the Company, and the amount 
of securities being sold during any three month period not exceeding the 
limitations specified in Rule 144(e), if applicable.
<PAGE>

         In the event that the Company does not qualify under Rule 701 at the
time of exercise of the Option, then the Shares may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires among other
things: (1) the resale occurring not less than two years after the party has
purchased, and made full payment for, within the meaning of Rule 144, the
securities to be sold; and, in the case of an affiliate, or of a non-affiliate
who has held the securities less than three years, (2) the availability of
certain public information about the Company, (3) the sale being made through a
broker in an unsolicited "broker's transaction"  or in transactions directly
with a "market maker," and (4) the amount of securities being sold during any
three month period not exceeding the specified limitations stated limitations
stated therein, if applicable.

         (e)  Optionee agrees, in connection with the Company's initial
underwritten public offering of the Company's securities, (1) not to sell, make
short sale of, loan, grant any options for the purchase of, or otherwise dispose
of any Shares of capital stock of the Company held by Optionee (other than those
Shares included in the registration) without the prior written consent of the
Company and the underwriters managing such initial underwritten public offering,
for one hundred eighty (180) days from the effective date of such registration,
and (2) further agrees to execute any agreement reflecting (1) above as may be
requested by the underwriters at the time of the public offering; provided,
however, that Optionee shall be relieved of the foregoing obligation in the
event the officers and directors of the Company also agree to similar
restrictions. Optionee agrees that, in order to ensure compliance with the
restrictions referred to herein, the Company may issue appropriate "stop
transfer" instructions to its transfer agent, if any, and that, if the Company
transfers its own securities, it may make appropriate notations to the same
effect in its own records.

         (f)  Optionee understands and agrees that the Company shall cause the
legends set forth below or legends substantially equivalent thereto, to be
placed upon any certificate(s) evidencing ownership of the Shares, together with
any other legends that may be required by state or Federal securities laws:

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
    1933 (THE "ACT"). THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
    HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO
    THE SECURITIES UNDER THE ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE
    COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

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

         (g)  REFUSAL TO TRANSFER. The Company shall not be required to: (i)
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) treat as owner of
such Shares or to accord the right to vote or pay dividends to any purchaser or
other transferee to whom such Shares shall have been transferred.

         (8)  to a broker-dealer licensed under the Code in a principal
transaction, or as an underwriter or member of an underwriting syndicate or

commissioner's written consent is obtained or under this rule not required;

         (10) by way of a sale qualified under Section 25111, 25112, 25113 or
25121 of the Code, of the securities to be transferred, provided that no order
under Section 25140 or Subdivision (a) of Section 25143 is in effect with
respect to such qualification;

corporation, or by a wholly owned subsidiary of a corporation to such

or by the administrator of the unclaimed property law of another state if, in 
either such case, such person (i) discloses to potential purchasers at the 
sale that transfer of the securities is restricted under this rule, (ii) 
delivers to each purchaser a copy of this rule, and (iii) advises the 
Commissioner of the name of each purchaser;

         (16) by a trustee to a successor trustee when such transfer does not
involve a change in the beneficial ownership of the securities;

         (17) by the way of an offer and sale of outstanding securities in an
issuer transaction that is subject to the qualification requirement of Section
25110 of the Code but exempt from that qualification requirement by subdivision
(f) of Section 25102;

providing that any such transfer is on the condition that certificate evidencing
the security issued to such transferee shall contain the legend required by this
section.

         (c)  The certificates representing all such securities subject to such
a restriction on transfer, whether upon initial issuance or upon any transfer
thereof, shall bear on their face a legend, prominently stamped or printed
thereon in capital letters of not less than 10-point size, reading as follows:

administered by different Committees with respect to different groups of 
Service Providers.

              (ii) SECTION 162(m). To the extent that the Administrator 
determines it to be desirable to qualify Options granted hereunder as 
"performance-based compensation" within the meaning of Section 162(m) of the 
Code, the Plan shall be administered by a Committee of two or more "outside 
directors" within the meaning of Section 162(m) of the Code.

                                      -4-

<PAGE>

              (iii) RULE 16b-3.  To the extent desirable to qualify 
transactions hereunder as exempt under Rule 16b-3, the transactions 
contemplated hereunder shall be structured to satisfy the requirements for 
exemption under Rule 16b-3.

              (iv) OTHER ADMINISTRATION.  Other than as provided above, the 
Plan shall be administered by (A) the Board or (B) a Committee, which 
committee shall be constituted to satisfy Applicable Laws. 

         (b)  POWERS OF THE ADMINISTRATOR.  Subject to the provisions of the 
Plan, and in the case of a Committee, subject to the specific duties 
delegated by the Board to such Committee, the Administrator shall have the 
authority, in its discretion:

              (i)  to determine the Fair Market Value;

              (ii) to select the Service Providers to whom Options and Stock 
Purchase Rights may be granted hereunder;

              (iii) to determine the number of shares of Common Stock to 
be covered by each Option and Stock Purchase Right granted hereunder;

              (iv) to approve forms of agreement for use under the Plan;

              (v)  to determine the terms and conditions, not inconsistent 
with the terms of the Plan, of any Option or Stock Purchase Right granted 
hereunder. Such terms and conditions include, but are not limited to, the 
exercise price, the time or times when Options or Stock Purchase Rights may 
be exercised (which may be based on performance criteria), any vesting 
acceleration or waiver of forfeiture restrictions, and any restriction or 
limitation regarding any Option or Stock Purchase Right of the shares of 
Common Stock relating thereto, based in each case on such factors as the 
Administrator, in its sole discretion, shall determine;

              (vi) to reduce the exercise price of any Option or Stock 
Purchase Right to the then current Fair Market Value if the Fair Market Value 
of the Common Stock covered by such Option or Stock Purchase Right shall have 
declined since the date the Option or Stock Purchase Right was granted;

              (vii) to institute an Option Exchange Program;

              (viii) to construe and interpret the terms of the Plan and 
awards granted pursuant to the Plan;

                                      -5-

<PAGE>

              (ix) to prescribe, amend and rescind rules and regulations 
relating to the Plan, including rules and regulations relating to sub-plans 
established for the purpose of qualifying for preferred tax treatment under 
foreign tax laws;

              (x)  to modify or amend each Option or Stock Purchase Right 
(subject to Section 15(c) of the Plan), including the discretionary authority 
to extend the post-termination exercisability period of Options longer than 
is otherwise provided for in the Plan;

              (xi) to allow Optionees to satisfy withholding tax obligations 
by electing to have the Company withhold from the Shares to be issued upon 
exercise of an Option or Stock Purchase Right that number of Shares having a 
Fair Market Value equal to the amount required to be withheld.  The Fair 
Market Value of the Shares to be withheld shall be determined on the date 
that the amount of tax to be withheld is to be determined.  All elections by 
an Optionee to have Shares withheld for this purpose shall be made in such 
form and under such conditions as the Administrator may deem necessary or 
advisable;

              (xii) to authorize any person to execute on behalf of the 
Company any instrument required to effect the grant of an Option or Stock 
Purchase Right previously granted by the Administrator;

              (xiii) to make all other determinations deemed necessary or 
advisable for administering the Plan.

         (c)  EFFECT OF ADMINISTRATOR'S DECISION.  The Administrator's 
decisions, determinations and interpretations shall be final and binding on 
all Optionees and any other holders of Options or Stock Purchase Rights.

    5.   ELIGIBILITY.  Nonstatutory Stock Options and Stock Purchase Rights 
may be granted to Service Providers.  Incentive Stock Options may be granted 
only to Employees.

    6.   LIMITATIONS.

         (a)  Each Option shall be designated in the Option Agreement as 
either an Incentive Stock Option or a Nonstatutory Stock Option.  However, 
notwithstanding such designation, to the extent that the aggregate Fair 
Market Value of the Shares with respect to which Incentive Stock Options are 
exercisable for the first time by the Optionee during any calendar year 
(under all plans of the Company and any Parent or Subsidiary) exceeds 
$100,000, such Options shall be treated as Nonstatutory Stock Options.  For 
purposes of this Section 6(a), Incentive Stock Options shall be taken into 
account in the order in which they were granted.  The Fair Market Value of 
the Shares shall be determined as of the time the Option with respect to such 
Shares is granted.

         (b)  Neither the Plan nor any Option or Stock Purchase Right shall 
confer upon an Optionee any right with respect to continuing the Optionee's 
relationship as a Service Provider with

                                      -6-

<PAGE>

the Company, nor shall they interfere in any way with the Optionee's right or 
the Company's right to terminate such relationship at any time, with or 
without cause.

         (c)  The following limitations shall apply to grants of Options:

              (i)  No Service Provider shall be granted, in any fiscal year 
of the Company, Options to purchase more than 500,000 Shares.

              (ii) In connection with his or her initial service, a Service 
Provider may be granted Options to purchase up to an additional 
250,000 Shares which shall not count against the limit set forth in 
subsection (i) above.

              (iii) The foregoing limitations shall be adjusted 
proportionately in connection with any change in the Company's capitalization 
as described in Section 13. 

              (iv) If an Option is cancelled in the same fiscal year of 
the Company in which it was granted (other than in connection with a 
transaction described in Section 13), the cancelled Option will be counted 
against the limits set forth in subsections (i) and (ii) above.  For this 
purpose, if the exercise price of an Option is reduced, the transaction will 
be treated as a cancellation of the Option and the grant of a new Option.

    7.   TERM OF PLAN.  Subject to Section 19 of the Plan, the Plan shall 
become effective upon its adoption by the Board.  It shall continue in effect 
for a term of ten (10) years unless terminated earlier under Section 15 of 
the Plan.

    8.   TERM OF OPTION.  The term of each Option shall be stated in the 
Option Agreement.  In the case of an Incentive Stock Option, the term shall 
be ten (10) years from the date of grant or such shorter term as may be 
provided in the Option Agreement.  Moreover, in the case of an Incentive 
Stock Option granted to an Optionee who, at the time the Incentive Stock 
Option is granted, owns stock representing more than ten percent (10%) of the 
total combined voting power of all classes of stock of the Company or any 
Parent or Subsidiary, the term of the Incentive Stock Option shall be five 
(5) years from the date of grant or such shorter term as may be provided in 
the Option Agreement.

    9.   OPTION EXERCISE PRICE AND CONSIDERATION.

         (a)  EXERCISE PRICE.  The per share exercise price for the Shares to 
be issued pursuant to exercise of an Option shall be determined by the 
Administrator, subject to the following:

              (i)  In the case of an Incentive Stock Option

                   (A)  granted to an Employee who, at the time the Incentive 
Stock Option is granted, owns stock representing more than ten percent (10%) 
of the voting power of all classes of

                                      -7-

<PAGE>

stock of the Company or any Parent or Subsidiary, the per Share exercise 
price shall be no less than 110% of the Fair Market Value per Share on the 
date of grant.

                   (B)  granted to any Employee other than an Employee 
described in paragraph (A) immediately above, the per Share exercise price 
shall be no less than 100% of the Fair Market Value per Share on the date of 
grant.

              (ii) In the case of a Nonstatutory Stock Option, the per Share 
exercise price shall be determined by the Administrator.  In the case of a 
Nonstatutory Stock Option intended to qualify as "performance-based 
compensation" within the meaning of Section 162(m) of the Code, the per Share 
exercise price shall be no less than 100% of the Fair Market Value per Share 
on the date of grant.

              (iii) Notwithstanding the foregoing, Options may be granted 
with a per Share exercise price of less than 100% of the Fair Market Value 
per Share on the date of grant pursuant to a merger or other corporate 
transaction.

         (b)  WAITING PERIOD AND EXERCISE DATES.  At the time an Option is 
granted, the Administrator shall fix the period within which the Option may 
be exercised and shall determine any conditions which must be satisfied 
before the Option may be exercised. 

         (c)  FORM OF CONSIDERATION.  The Administrator shall determine the 
acceptable form of consideration for exercising an Option, including the 
method of payment.  In the case of an Incentive Stock Option, the 
Administrator shall determine the acceptable form of consideration at the 
time of grant.  Such consideration may consist entirely of:

              (i)  cash;

              (ii) check;

              (iii) promissory note;

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

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

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

                                     -8-

<PAGE>

              (vii) any combination of the foregoing methods of payment; 
or

              (viii) such other consideration and method of payment for 
the issuance of Shares to the extent permitted by Applicable Laws.

    10.  EXERCISE OF OPTION.

         (a)  PROCEDURE FOR EXERCISE; RIGHTS AS A SHAREHOLDER. Any Option 
granted hereunder shall be exercisable according to the terms of the Plan and 
at such times and under such conditions as determined by the Administrator 
and set forth in the Option Agreement.  Unless the Administrator provides 
otherwise, vesting of Options granted hereunder shall be tolled during any 
unpaid leave of absence.  An Option may not be exercised for a fraction of a 
Share.

              An Option shall be deemed exercised when the Company receives: 
(i) written or electronic notice of exercise (in accordance with the Option 
Agreement) from the person entitled to exercise the Option, and (ii) full 
payment for the Shares with respect to which the Option is exercised.  Full 
payment may consist of any consideration and method of payment authorized by 
the Administrator and permitted by the Option Agreement and the Plan.  Shares 
issued upon exercise of an Option shall be issued in the name of the Optionee 
or, if requested by the Optionee, in the name of the Optionee and his or her 
spouse. Until the Shares are issued (as evidenced by the appropriate entry on 
the books of the Company or of a duly authorized transfer agent of the 
Company), no right to vote or receive dividends or any other rights as a 
shareholder shall exist with respect to the Optioned Stock, notwithstanding 
the exercise of the Option. The Company shall issue (or cause to be issued) 
such Shares promptly after the Option is exercised.  No adjustment will be 
made for a dividend or other right for which the record date is prior to the 
date the Shares are issued, except as provided in Section 13 of the Plan.

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

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

                                      -9-

<PAGE>

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

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

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

    11.  STOCK PURCHASE RIGHTS.

         (a)  RIGHTS TO PURCHASE.  Stock Purchase Rights may be issued either 
alone, in addition to, or in tandem with other awards granted under the Plan 
and/or cash awards made outside of the Plan.  After the Administrator 
determines that it will offer Stock Purchase Rights under the Plan, it shall 
advise the offeree in writing or electronically, by means of a Notice of 
Grant, of the terms, conditions and restrictions related to the offer, 
including the number of Shares that the offeree shall be entitled to 
purchase, the price to be paid, and the time within which the offeree must 
accept such offer.  The offer shall be accepted by execution of a Restricted 
Stock Purchase Agreement in the form determined by the Administrator.

         (b)  REPURCHASE OPTION.  Unless the Administrator determines 
otherwise, the Restricted Stock Purchase Agreement shall grant the Company a 
repurchase option exercisable upon the voluntary or involuntary termination 
of the purchaser's service with the Company for any reason (including death 
or Disability).  The purchase price for Shares repurchased pursuant to the 
Restricted Stock Purchase Agreement shall be the original price paid by the 
purchaser and may be paid by

                                     -10-

<PAGE>

cancellation of any indebtedness of the purchaser to the Company.  The 
repurchase option shall lapse at a rate determined by the Administrator.

         (c)  OTHER PROVISIONS.  The Restricted Stock Purchase Agreement 
shall contain such other terms, provisions and conditions not inconsistent 
with the Plan as may be determined by the Administrator in its sole 
discretion. 

         (d)  RIGHTS AS A SHAREHOLDER.  Once the Stock Purchase Right is 
exercised, the purchaser shall have the rights equivalent to those of a 
shareholder, and shall be a shareholder when his or her purchase is entered 
upon the records of the duly authorized transfer agent of the Company.  No 
adjustment will be made for a dividend or other right for which the record 
date is prior to the date the Stock Purchase Right is exercised, except as 
provided in Section 13 of the Plan.

    12.  NON-TRANSFERABILITY OF OPTIONS AND STOCK PURCHASE RIGHTS.  Unless 
determined otherwise by the Administrator, an Option or Stock Purchase Right 
may not be sold, pledged, assigned, hypothecated, transferred, or disposed of 
in any manner other than by will or by the laws of descent or distribution 
and may be exercised, during the lifetime of the Optionee, only by the 
Optionee.  If the Administrator makes an Option or Stock Purchase Right 
transferable, such Option or Stock Purchase Right shall contain such 
additional terms and conditions as the Administrator deems appropriate.

    13.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, MERGER OR   
       ASSET SALE. 

         (a)  CHANGES IN CAPITALIZATION.  Subject to any required action by 
the shareholders of the Company, the number of shares of Common Stock covered 
by each outstanding Option and Stock Purchase Right, and the number of shares 
of Common Stock which have been authorized for issuance under the Plan but as 
to which no Options or Stock Purchase Rights have yet been granted or which 
have been returned to the Plan upon cancellation or expiration of an Option 
or Stock Purchase Right, as well as the price per share of Common Stock 
covered by each such outstanding Option or Stock Purchase Right, shall be 
proportionately adjusted for any increase or decrease in the number of issued 
shares of Common Stock resulting from a stock split, reverse stock split, 
stock dividend, combination or reclassification of the Common Stock, or any 
other increase or decrease in the number of issued shares of Common Stock 
effected without receipt of consideration by the Company; provided, however, 
that conversion of any convertible securities of the Company shall not be 
deemed to have been "effected without receipt of consideration."  Such 
adjustment shall be made by the Board, whose determination in that respect 
shall be final, binding and conclusive. Except as expressly provided herein, 
no issuance by the Company of shares of stock of any class, or securities 
convertible into shares of stock of any class, shall affect, and no 
adjustment by reason thereof shall be made with respect to, the number or 
price of shares of Common Stock subject to an Option or Stock Purchase Right.

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

         (c)  MERGER OR ASSET SALE.  In the event of a merger of the Company 
with or into another corporation, or the sale of substantially all of the 
assets of the Company, each outstanding Option and Stock Purchase Right shall 
be assumed or an equivalent option or right substituted by the successor 
corporation or a Parent or Subsidiary of the successor corporation.  In the 
event that the successor corporation refuses to assume or substitute for the 
Option or Stock Purchase Right, the Optionee shall fully vest in and have the 
right to exercise the Option or Stock Purchase Right as to all of the 
Optioned Stock, including Shares as to which it would not otherwise be vested 
or exercisable.  If an Option or Stock Purchase Right becomes fully vested 
and exercisable in lieu of assumption or substitution in the event of a 
merger or sale of assets, the Administrator shall notify the Optionee in 
writing or electronically that the Option or Stock Purchase Right shall be 
fully vested and exercisable for a period of fifteen (15) days from the date 
of such notice, and the Option or Stock Purchase Right shall terminate upon 
the expiration of such period.  For the purposes of this paragraph, the 
Option or Stock Purchase Right shall be considered assumed if, following the 
merger or sale of assets, the

                                     -12-

<PAGE>

option or right confers the right to purchase or receive, for each Share of 
Optioned Stock subject to the Option or Stock Purchase Right immediately 
prior to the merger or sale of assets, the consideration (whether stock, 
cash, or other securities or property) received in the merger or sale of 
assets by holders of Common Stock for each Share held on the effective date 
of the transaction (and if holders were offered a choice of consideration, 
the type of consideration chosen by the holders of a majority of the 
outstanding Shares); provided, however, that if such consideration received 
in the merger or sale of assets is not solely common stock of the successor 
corporation or its Parent, the Administrator may, with the consent of the 
successor corporation, provide for the consideration to be received upon the 
exercise of the Option or Stock Purchase Right, for each Share of Optioned 
Stock subject to the Option or Stock Purchase Right, to be solely common 
stock of the successor corporation or its Parent equal in fair market value 
to the per share consideration received by holders of Common Stock in the 
merger or sale of assets.

    14.  DATE OF GRANT.  The date of grant of an Option or Stock Purchase 
Right shall be, for all purposes, the date on which the Administrator makes 
the determination granting such Option or Stock Purchase Right, or such other 
later date as is determined by the Administrator.  Notice of the 
determination shall be provided to each Optionee within a reasonable time 
after the date of such grant.

    15.  AMENDMENT AND TERMINATION OF THE PLAN.

         (a)  AMENDMENT AND TERMINATION.  The Board may at any time amend, 
alter, suspend or terminate the Plan.  

         (b)  SHAREHOLDER APPROVAL.  The Company shall obtain shareholder 
approval of any Plan amendment to the extent necessary and desirable to 
comply with Applicable Laws. 

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

    16.  CONDITIONS UPON ISSUANCE OF SHARES.  

         (a)  LEGAL COMPLIANCE.  Shares shall not be issued pursuant to the 
exercise of an Option or Stock Purchase Right unless the exercise of such 
Option or Stock Purchase Right and the issuance and delivery of such Shares 
shall comply with Applicable Laws and shall be further subject to the 
approval of counsel for the Company with respect to such compliance.

         (b)  INVESTMENT REPRESENTATIONS.  As a condition to the exercise of 
an Option or Stock Purchase Right, the Company may require the person 
exercising such Option or Stock Purchase Right to represent and warrant at 
the time of any such exercise that the Shares are being purchased only for

                                     -13-

<PAGE>

investment and without any present intention to sell or distribute such 
Shares if, in the opinion of counsel for the Company, such a representation 
is required.

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

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

    19.  SHAREHOLDER APPROVAL.  The Plan shall be subject to approval by the 
shareholders of the Company within twelve (12) months after the date the Plan 
is adopted.  Such shareholder approval shall be obtained in the manner and to 
the degree required under Applicable Laws.

    Term/Expiration Date:              _________________________


  VESTING SCHEDULE:

    This Option may be exercised, in whole or in part, in accordance with the 
following schedule:

    [25% of the Shares subject to the Option shall vest twelve months after 
the Vesting Commencement Date, and 1/48 of the Shares subject to the Option 
shall vest each month thereafter, subject to the Optionee continuing to be 
a Service Provider on such dates].

<PAGE>


    TERMINATION PERIOD:

    This Option may be exercised for [three months] after Optionee ceases to 
be a Service Provider.  Upon the death or Disability of the Optionee, this 
Option may be exercised for [one year] after Optionee ceases to be a Service 
Provider. In no event shall this Option be exercised later than the 
Term/Expiration Date as provided above.

II.  AGREEMENT

    1.   GRANT OF OPTION.  The Plan Administrator of the Company hereby 
grants to the Optionee named in the Notice of Grant attached as Part I of 
this Agreement (the "Optionee") an option (the "Option") to purchase the 
number of Shares, as set forth in the Notice of Grant, at the exercise price 
per share set forth in the Notice of Grant (the "Exercise Price"), subject to 
the terms and conditions of the Plan, which is incorporated herein by 
reference.  Subject to Section 15(c) of the Plan, in the event of a conflict 
between the terms and conditions of the Plan and the terms and conditions of 
this Option Agreement, the terms and conditions of the Plan shall prevail.

         If designated in the Notice of Grant as an Incentive Stock Option 
("ISO"), this Option is intended to qualify as an Incentive Stock Option 
under Section 422 of the Code.  However, if this Option is intended to be an 
Incentive Stock Option, to the extent that it exceeds the $100,000 rule of 
Code Section 422(d) it shall be treated as a Nonstatutory Stock Option 
("NSO").

    2.   EXERCISE OF OPTION.

         (a)  RIGHT TO EXERCISE.  This Option is exercisable during its term 
in accordance with the Vesting Schedule set out in the Notice of Grant and 
the applicable provisions of the Plan and this Option Agreement.

         (b)  METHOD OF EXERCISE.  This Option is exercisable by delivery of 
an exercise notice, in the form attached as Exhibit A (the "Exercise 
Notice"), which shall state the election to exercise the Option, the number 
of Shares in respect of which the Option is being exercised (the "Exercised 
Shares"), and such other representations and agreements as may be required by 
the Company pursuant to the provisions of the Plan.  The Exercise Notice 
shall be completed by the Optionee and delivered to [Secretary] of the 
Company.  The Exercise Notice shall be accompanied by payment of the 
aggregate Exercise Price as to all Exercised Shares.  This Option shall be 
deemed to be exercised upon receipt by the Company of such fully executed 
Exercise Notice accompanied by such aggregate Exercise Price.

         No Shares shall be issued pursuant to the exercise of this Option 
unless such issuance and exercise complies with Applicable Laws.  Assuming 
such compliance, for income tax purposes the Exercised Shares shall be 
considered transferred to the Optionee on the date the Option is exercised 
with respect to such Exercised Shares.

                                     -2-

<PAGE>

    3.   METHOD OF PAYMENT.  Payment of the aggregate Exercise Price shall be 
by any of the following, or a combination thereof, at the election of the 
Optionee:

         (a)  cash; or

         (b)  check; or

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

         (d)  surrender of other Shares which (i) in the case of Shares 
acquired upon exercise of an option, have been owned by the Optionee for more 
than six (6) months on the date of surrender, AND (ii) have a Fair Market 
Value on the date of surrender equal to the aggregate Exercise Price of the 
Exercised Shares.

    4.   NON-TRANSFERABILITY OF OPTION.  This Option may not be transferred 
in any manner otherwise than by will or by the laws of descent or 
distribution and may be exercised during the lifetime of Optionee only by the 
Optionee.  The terms of the Plan and this Option Agreement shall be binding 
upon the executors, administrators, heirs, successors and assigns of the 
Optionee.

    5.   TERM OF OPTION.  This Option may be exercised only within the term 
set out in the Notice of Grant, and may be exercised during such term only in 
accordance with the Plan and the terms of this Option Agreement.

    6.   TAX CONSEQUENCES.  Some of the federal tax consequences relating to 
this Option, as of the date of this Option, are set forth below.  THIS 
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE 
SUBJECT TO CHANGE.  THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE 
EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

         (a)  EXERCISING THE OPTION.

              (i)  NONSTATUTORY STOCK OPTION.  The Optionee may incur regular 
federal income tax liability upon exercise of a NSO.  The Optionee will be 
treated as having received compensation income (taxable at ordinary income 
tax rates) equal to the excess, if any, of the Fair Market Value of the 
Exercised Shares on the date of exercise over their aggregate Exercise Price. 
 If the Optionee is an Employee or a former Employee, the Company will be 
required to withhold from his or her compensation or collect from Optionee 
and pay to the applicable taxing authorities an amount in cash equal to a 
percentage of this compensation income at the time of exercise, and may 
refuse to honor the exercise and refuse to deliver Shares if such withholding 
amounts are not delivered at the time of exercise.

              (ii) INCENTIVE STOCK OPTION.  If this Option qualifies as an 
ISO, the Optionee will have no regular federal income tax liability upon its 
exercise, although the excess, if any, of the Fair

                                      -3-

<PAGE>

Market Value of the Exercised Shares on the date of exercise over their 
aggregate Exercise Price will be treated as an adjustment to alternative 
minimum taxable income for federal tax purposes and may subject the Optionee 
to alternative minimum tax in the year of exercise.  In the event that the 
Optionee ceases to be an Employee but remains a Service Provider, any 
Incentive Stock Option of the Optionee that remains unexercised shall cease 
to qualify as an Incentive Stock Option and will be treated for tax purposes 
as a Nonstatutory Stock Option on the date three (3) months and one (1) day 
following such change of status.

         (b)  DISPOSITION OF SHARES.  

              (i)  NSO.  If the Optionee holds NSO Shares for at least one 
year, any gain realized on disposition of the Shares will be treated as 
long-term capital gain for federal income tax purposes.

              (ii) ISO.  If the Optionee holds ISO Shares for at least one 
year after exercise and two years after the grant date, any gain realized on 
disposition of the Shares will be treated as long-term capital gain for 
federal income tax purposes.  If the Optionee disposes of ISO Shares within 
one year after exercise or two years after the grant date, any gain realized 
on such disposition will be treated as compensation income (taxable at 
ordinary income rates) to the extent of the excess, if any, of the lesser of 
(A) the difference between the Fair Market Value of the Shares acquired on 
the date of exercise and the aggregate Exercise Price, or (B) the difference 
between the sale price of such Shares and the aggregate Exercise Price.  Any 
additional gain will be taxed as capital gain, short-term or long-term 
depending on the period that the ISO Shares were held.

         (c)  NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES.  If the 
Optionee sells or otherwise disposes of any of the Shares acquired pursuant 
to an ISO on or before the later of (i) two years after the grant date, or 
(ii) one year after the exercise date, the Optionee shall immediately notify 
the Company in writing of such disposition.  The Optionee agrees that he or 
she may be subject to income tax withholding by the Company on the 
compensation income recognized from such early disposition of ISO Shares by 
payment in cash or out of the current earnings paid to the Optionee.

    7.   ENTIRE AGREEMENT; GOVERNING LAW.  The Plan is incorporated herein by 
reference.  The Plan and this Option Agreement constitute the entire 
agreement of the parties with respect to the subject matter hereof and 
supersede in their entirety all prior undertakings and agreements of the 
Company and Optionee with respect to the subject matter hereof, and may not 
be modified adversely to the Optionee's interest except by means of a writing 
signed by the Company and Optionee.  This agreement is governed by the 
internal substantive laws, but not the choice of law rules, of California.

    8.   NO GUARANTEE OF CONTINUED SERVICE.  OPTIONEE ACKNOWLEDGES AND AGREES 
THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED 
ONLY BY CONTINUING AS A SERVICE PROVIDER AT THE WILL OF THE COMPANY (AND NOT 
THROUGH THE ACT OF BEING HIRED, BEING GRANTED AN OPTION OR PURCHASING SHARES 
HEREUNDER).  OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT THIS AGREEMENT, 
THE TRANSACTIONS

                                      -4-

<PAGE>

CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT 
CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE 
PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT 
INTERFERE WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO TERMINATE 
OPTIONEE'S RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT 
CAUSE.

    By your signature and the signature of the Company's representative 
below, you and the Company agree that this Option is granted under and 
governed by the terms and conditions of the Plan and this Option Agreement.  
Optionee has reviewed the Plan and this Option Agreement in their entirety, 
has had an opportunity to obtain the advice of counsel prior to executing 
this Option Agreement and fully understands all provisions of the Plan and 
Option Agreement. Optionee hereby agrees to accept as binding, conclusive and 
final all decisions or interpretations of the Administrator upon any 
questions relating to the Plan and Option Agreement.  Optionee further agrees 
to notify the Company upon any change in the residence address indicated 
below.

                       1997 EMPLOYEE STOCK PURCHASE PLAN


    The following constitute the provisions of the 1997 Employee Stock 
Purchase Plan of Livingston Enterprises, Inc.

    1.   PURPOSE.  The purpose of the Plan is to provide employees of the 
Company and its Designated Subsidiaries with an opportunity to purchase 
Common Stock of the Company through accumulated payroll deductions.  It is 
the intention of the Company to have the Plan qualify as an "Employee Stock 
Purchase Plan" under Section 423 of the Internal Revenue Code of 1986, as 
amended.  The provisions of the Plan, accordingly, shall be construed so as 
to extend and limit participation in a manner consistent with the 
requirements of that section of the Code.

    2.   DEFINITIONS.

         (a)  "BOARD" shall mean the Board of Directors of the Company.

         (b)  "CODE" shall mean the Internal Revenue Code of 1986, as amended.

         (d)  "COMPANY" shall mean Livingston Enterprises, Inc. and any 
Designated Subsidiary of the Company.

         (e)  "COMPENSATION" shall mean all base straight time gross 
earnings, commissions and overtime payments, but exclusive of payments for 
shift premium, incentive compensation, incentive payments, bonuses and other 
compensation.

         (f)  "DESIGNATED SUBSIDIARY" shall mean any Subsidiary which has 
been designated by the Board from time to time in its sole discretion as 
eligible to participate in the Plan.

         (g)  "EMPLOYEE" shall mean any individual who is an Employee of the 
Company for tax purposes whose customary employment with the Company is at 
least twenty (20) hours per week and more than five (5) months in any 
calendar year. For purposes of the Plan, the employment relationship shall be 
treated as continuing intact while the individual is on sick leave or other 
leave of absence approved by the Company.  Where the period of leave exceeds 
90 days and the individual's right to reemployment is not guaranteed either 
by statute or by contract, the employment relationship shall be deemed to 
have terminated on the 91st day of such leave. 

         (h)  "ENROLLMENT DATE" shall mean the first day of each Offering 
Period.

<PAGE>

the public as set forth in the final prospectus included within the

         (b)  Any provisions of the Plan to the contrary notwithstanding, no 
Employee shall be granted an option under the Plan (i) to the extent that, 
immediately after the grant, such Employee (or any other person whose stock 
would be attributed to such Employee pursuant to Section 424(d) of the Code) 
would own capital stock of the Company and/or hold outstanding options to 
purchase such stock possessing five percent (5%) or more of the total 
combined voting power or value of all classes of the capital stock of the 
Company or of any Subsidiary, or (ii) to the extent that his or her rights to 
purchase stock under all employee stock purchase plans of the Company and its 
subsidiaries accrues at a rate which exceeds Twenty-Five Thousand Dollars 
($25,000) worth of stock (determined at the fair market value of the shares 
at the time such option is granted) for each calendar year in which such 
option is outstanding at any time.

    4.   OFFERING PERIODS.  The Plan shall be implemented by consecutive, 
overlapping Offering Periods with a new Offering Period commencing on the

to change the duration of Offering Periods (including the commencement dates

such change is announced at least five (5) days prior to the scheduled 
beginning of the first Offering Period to be affected thereafter.

    5.   PARTICIPATION.

         (a)  An eligible Employee may become a participant in the Plan by 
completing a subscription agreement authorizing payroll deductions in the 
form of Exhibit A to this Plan and filing it with the Company's payroll 
office prior to the applicable Enrollment Date.

                                     -3-

<PAGE>

         (b)  Payroll deductions for a participant shall commence on the 
first payroll following the Enrollment Date and shall end on the last payroll 
in the Offering Period to which such authorization is applicable, unless 
sooner terminated by the participant as provided in Section 10 hereof. 

    6.   PAYROLL DEDUCTIONS.

         (a)       At the time a participant files his or her subscription 
agreement, he or she shall elect to have payroll deductions made on each pay 
day during the Offering Period in an amount not exceeding ten (10%) of the 
Compensation which he or she receives on each pay day during the Offering 
Period. 

         (b)  All payroll deductions made for a participant shall be credited 
to his or her account under the Plan and shall be withheld in whole 
percentages only.  A participant may not make any additional payments into 
such account.

         (c)  A participant may discontinue his or her participation in the 
Plan as provided in Section 10 hereof, or may increase or decrease the rate 
of his or her payroll deductions during the Offering Period by completing or 
filing with the Company a new subscription agreement authorizing a change in 
payroll deduction rate.  The Board may, in its discretion, limit the number 
of participation rate changes during any Offering Period.  The change in rate 
shall be effective with the first full payroll period following five (5) 
business days after the Company's receipt of the new subscription agreement 
unless the Company elects to process a given change in participation more 
quickly.  A participant's subscription agreement shall remain in effect for 
successive Offering Periods unless terminated as provided in Section 10 
hereof.

         (d)  Notwithstanding the foregoing, to the extent necessary to 
comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a 
participant's payroll deductions may be decreased to zero percent (0%) at any 
time during a Purchase Period.  Payroll deductions shall recommence at the 
rate provided in such participant's subscription agreement at the beginning 
of the first Purchase Period which is scheduled to end in the following 
calendar year, unless terminated by the participant as provided in Section 10 
hereof.

         (e)  At the time the option is exercised, in whole or in part, or at 
the time some or all of the Company's Common Stock issued under the Plan is 
disposed of, the participant must make adequate provision for the Company's 
federal, state, or other tax withholding obligations, if any, which arise 
upon the exercise of the option or the disposition of the Common Stock.  At 
any time, the Company may, but shall not be obligated to, withhold from the 
participant's compensation the amount necessary for the Company to meet 
applicable withholding obligations, including any withholding required to 
make available to the Company any tax deductions or benefits attributable to 
sale or early disposition of Common Stock by the Employee. 

                                      -4-

<PAGE>

    7.   GRANT OF OPTION.  On the Enrollment Date of each Offering Period, 
each eligible Employee participating in such Offering Period shall be granted 
an option to purchase on each Exercise Date during such Offering Period (at 
the applicable Purchase Price) up to a number of shares of the Company's 
Common Stock determined by dividing such Employee's payroll deductions 
accumulated prior to such Exercise Date and retained in the Participant's 
account as of the Exercise Date by the applicable Purchase Price; provided 
that in no event shall an Employee be permitted to purchase during each 
Purchase Period more than [2,500] shares of the Company's Common Stock 
(subject to any adjustment pursuant to Section 19) on the Enrollment Date, 
and provided further that such purchase shall be subject to the limitations 
set forth in Sections 3(b) and 12 hereof. Exercise of the option shall occur 
as provided in Section 8 hereof, unless the participant has withdrawn 
pursuant to Section 10 hereof.  The option shall expire on the last day of 
the Offering Period. 

    8.   EXERCISE OF OPTION.  Unless a participant withdraws from the Plan as 
provided in Section 10 hereof, his or her option for the purchase of shares 
shall be exercised automatically on the Exercise Date, and the maximum number 
of full shares subject to option shall be purchased for such participant at 
the applicable Purchase Price with the accumulated payroll deductions in his 
or her account.  No fractional shares shall be purchased; any payroll 
deductions accumulated in a participant's account which are not sufficient to 
purchase a full share shall be retained in the participant's account for the 
subsequent Purchase Period or Offering Period, subject to earlier withdrawal 
by the participant as provided in Section 10 hereof.  Any other monies left 
over in a participant's account after the Exercise Date shall be returned to 
the participant.  During a participant's lifetime, a participant's option to 
purchase shares hereunder is exercisable only by him or her.

    9.   DELIVERY.  As promptly as practicable after each Exercise Date on 
which a purchase of shares occurs, the Company shall arrange the delivery to 
each participant, as appropriate, of a certificate representing the shares 
purchased upon exercise of his or her option.

    10.  WITHDRAWAL.

         (a)  A participant may withdraw all but not less than all the 
payroll deductions credited to his or her account and not yet used to 
exercise his or her option under the Plan at any time by giving written 
notice to the Company in the form of Exhibit B to this Plan.  All of the 
participant's payroll deductions credited to his or her account shall be paid 
to such participant promptly after receipt of notice of withdrawal and such 
participant's option for the Offering Period shall be automatically 
terminated, and no further payroll deductions for the purchase of shares 
shall be made for such Offering Period.  If a participant withdraws from an 
Offering Period, payroll deductions shall not resume at the beginning of the 
succeeding Offering Period unless the participant delivers to the Company a 
new subscription agreement.

         (b)  A participant's withdrawal from an Offering Period shall not 
have any effect upon his or her eligibility to participate in any similar 
plan which may hereafter be adopted by the Company or in succeeding Offering 
Periods which commence after the termination of the Offering Period from 
which the participant withdraws.

    11.  TERMINATION OF EMPLOYMENT.  

         Upon a participant's ceasing to be an Employee, for any reason, he 
or she shall be deemed to have elected to withdraw from the Plan and the 
payroll deductions credited to such participant's account during the Offering 
Period but not yet used to exercise the option shall be returned to such 
participant or, in the case of his or her death, to the person or persons 
entitled thereto under Section 15 hereof, and such participant's option shall 
be automatically terminated.  The preceding sentence notwithstanding, a 
participant who receives payment in lieu of notice of termination of 
employment shall be treated as continuing to be an Employee for the 
participant's customary number of hours per week of employment during the 
period in which the participant is subject to such payment in lieu of notice.

    12.  INTEREST.  No interest shall accrue on the payroll deductions of a 
participant in the Plan.

    13.  STOCK.

         (a)  The maximum number of shares of the Company's Common Stock 
which shall be made available for sale under the Plan shall be 500,000 
shares, plus an annual increase to be added on each anniversary date of the 
adoption of the Plan equal to the lesser of (i) 150,000 shares, (ii) 1% of 
the outstanding shares on such date or (iii) a lesser amount determined by 
the Board, subject to adjustment upon changes in capitalization of the 
Company as provided in Section 19 hereof.  If, on a given Exercise Date, the 
number of shares with respect to which options are to be exercised exceeds 
the number of shares then available under the Plan, the Company shall make a 
pro rata allocation of the shares remaining available for purchase in as 
uniform a manner as shall be practicable and as it shall determine to be 
equitable.

         (b)  The participant shall have no interest or voting right in 
shares covered by his option until such option has been exercised.

         (c)  Shares to be delivered to a participant under the Plan shall be 
registered in the name of the participant or in the name of the participant 
and his or her spouse.

    14.  ADMINISTRATION.  The Plan shall be administered by the Board or a 
committee of members of the Board appointed by the Board.  The Board or its 
committee shall have full and exclusive discretionary authority to construe, 
interpret and apply the terms of the Plan, to determine eligibility and to 
adjudicate all disputed claims filed under the Plan.  Every finding, decision 
and determination made by the Board or its committee shall, to the full 
extent permitted by law, be final and binding upon all parties.

    15.  DESIGNATION OF BENEFICIARY.

         (a)  A participant may file a written designation of a beneficiary 
who is to receive any shares and cash, if any, from the participant's account 
under the Plan in the event of such partici-

                                      -6-

<PAGE>

pant's death subsequent to an Exercise Date on which the option is exercised 
but prior to delivery to such participant of such shares and cash.  In 
addition, a participant may file a written designation of a beneficiary who 
is to receive any cash from the participant's account under the Plan in the 
event of such participant's death prior to exercise of the option.  If a 
participant is married and the designated beneficiary is not the spouse, 
spousal consent shall be required for such designation to be effective.

         (b)  Such designation of beneficiary may be changed by the 
participant at any time by written notice.  In the event of the death of a 
participant and in the absence of a beneficiary validly designated under the 
Plan who is living at the time of such participant's death, the Company shall 
deliver such shares and/or cash to the executor or administrator of the 
estate of the participant, or if no such executor or administrator has been 
appointed (to the knowledge of the Company), the Company, in its discretion, 
may deliver such shares and/or cash to the spouse or to any one or more 
dependents or relatives of the participant, or if no spouse, dependent or 
relative is known to the Company, then to such other person as the Company 
may designate.

    16.  TRANSFERABILITY.  Neither payroll deductions credited to a 
participant's account nor any rights with regard to the exercise of an option 
or to receive shares under the Plan may be assigned, transferred, pledged or 
otherwise disposed of in any way (other than by will, the laws of descent and 
distribution or as provided in Section 15 hereof) by the participant.  Any 
such attempt at assignment, transfer, pledge or other disposition shall be 
without effect, except that the Company may treat such act as an election to 
withdraw funds from an Offering Period in accordance with Section 10 hereof.

    17.  USE OF FUNDS.  All payroll deductions received or held by the 
Company under the Plan may be used by the Company for any corporate purpose, 
and the Company shall not be obligated to segregate such payroll deductions.

    18.  REPORTS.  Individual accounts shall be maintained for each 
participant in the Plan.  Statements of account shall be given to 
participating Employees at least annually, which statements shall set forth 
the amounts of payroll deductions, the Purchase Price, the number of shares 
purchased and the remaining cash balance, if any.

    19.  ADJUSTMENTS UPON CHANGES IN CAPITALIZATION, DISSOLUTION, 
         LIQUIDATION, MERGER OR ASSET SALE.

         (a)  CHANGES IN CAPITALIZATION.  Subject to any required action by 
the shareholders of the Company, the Reserves, the maximum number of shares 
each participant may purchase each Purchase Period (pursuant to Section 7), 
as well as the price per share and the number of shares of Common Stock 
covered by each option under the Plan which has not yet been exercised shall 
be proportionately adjusted for any increase or decrease in the number of 
issued shares of Common Stock resulting from a stock split, reverse stock 
split, stock dividend, combination or reclassification of the Common Stock, 
or any other increase or decrease in the number of shares of Common Stock 
effected without receipt of consideration by the Company; provided, however, 
that conversion of any convertible securities of the Company shall not be 
deemed to have been "effected without receipt of consideration".  Such 
adjustment shall be made by the Board, whose determination in that respect 

                                      -7-

<PAGE>

shall be final, binding and conclusive. Except as expressly provided herein, 
no issuance by the Company of shares of stock of any class, or securities 
convertible into shares of stock of any class, shall affect, and no 
adjustment by reason thereof shall be made with respect to, the number or 
price of shares of Common Stock subject to an option.

         (b)  DISSOLUTION OR LIQUIDATION. In the event of the proposed 
dissolution or liquidation of the Company, the Offering Period then in 
progress shall be shortened by setting a new Exercise Date (the "New Exercise 
Date"), and shall terminate immediately prior to the consummation of such 
proposed dissolution or liquidation, unless provided otherwise by the Board.  
The New Exercise Date shall be before the date of the Company's proposed 
dissolution or liquidation.  The Board shall notify each participant in 
writing, at least ten (10) business days prior to the New Exercise Date, that 
the Exercise Date for the participant's option has been changed to the New 
Exercise Date and that the participant's option shall be exercised 
automatically on the New Exercise Date, unless prior to such date the 
participant has withdrawn from the Offering Period as provided in Section 10 
hereof.  

         (c)  MERGER OR ASSET SALE.  In the event of a proposed sale of all 
or substantially all of the assets of the Company, or the merger of the 
Company with or into another corporation, each outstanding option shall be 
assumed or an equivalent option substituted by the successor corporation or a 
Parent or Subsidiary of the successor corporation.  In the event that the 
successor corporation refuses to assume or substitute for the option, any 
Purchase Periods then in progress shall be shortened by setting a new 
Exercise Date (the "New Exercise Date") and any Offering Periods then in 
progress shall end on the New Exercise Date.  The New Exercise Date shall be 
before the date of the Company's proposed sale or merger.  The Board shall 
notify each participant in writing, at least ten (10) business days prior to 
the New Exercise Date, that the Exercise Date for the participant's option 
has been changed to the New Exercise Date and that the participant's option 
shall be exercised automatically on the New Exercise Date, unless prior to 
such date the participant has withdrawn from the Offering Period as provided 
in Section 10 hereof.

    20.  AMENDMENT OR TERMINATION.

         (a)  The Board of Directors of the Company may at any time and for 
any reason terminate or amend the Plan.  Except as provided in Section 19 
hereof, no such termination can affect options previously granted, provided 
that an Offering Period may be terminated by the Board of Directors on any 
Exercise Date if the Board determines that the termination of the Plan is in 
the best interests of the Company and its shareholders.  Except as provided 
in Section 19 hereof, no amendment may make any change in any option 
theretofore granted which adversely affects the rights of any participant.  
To the extent necessary to comply with Section 423 of the Code (or any 
successor rule or provision or any other applicable law, regulation or stock 
exchange rule), the Company shall obtain shareholder approval in such a 
manner and to such a degree as required.

         (b)  Without shareholder consent and without regard to whether any 
participant rights may be considered to have been "adversely affected," the 
Board (or its committee) shall be entitled to change the Offering Periods, 
limit the frequency and/or number of changes in the amount

                                     -8-

<PAGE>

withheld during an Offering Period, establish the exchange ratio applicable 
to amounts withheld in a currency other than U.S. dollars, permit payroll 
withholding in excess of the amount designated by a participant in order to 
adjust for delays or mistakes in the Company's processing of properly 
completed withholding elections, establish reasonable waiting and adjustment 
periods and/or accounting and crediting procedures to ensure that amounts 
applied toward the purchase of Common Stock for each participant properly 
correspond with amounts withheld from the participant's Compensation, and 
establish such other limitations or procedures as the Board (or its 
committee) determines in its sole discretion advisable which are consistent 
with the Plan.

    21.  NOTICES.  All notices or other communications by a participant to 
the Company under or in connection with the Plan shall be deemed to have been 
duly given when received in the form specified by the Company at the 
location, or by the person, designated by the Company for the receipt thereof.

    22.  CONDITIONS UPON ISSUANCE OF SHARES.  Shares shall not be issued with 
respect to an option unless the exercise of such option and the issuance and 
delivery of such shares pursuant thereto shall comply with all applicable 
provisions of law, domestic or foreign, including, without limitation, the 
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as 
amended, the rules and regulations promulgated thereunder, and the 
requirements of any stock exchange upon which the shares may then be listed, 
and shall be further subject to the approval of counsel for the Company with 
respect to such compliance.

         As a condition to the exercise of an option, the Company may require 
the person exercising such option to represent and warrant at the time of any 
such exercise that the shares are being purchased only for investment and 
without any present intention to sell or distribute such shares if, in the 
opinion of counsel for the Company, such a representation is required by any 
of the aforementioned applicable provisions of law.

    23.  TERM OF PLAN.  The Plan shall become effective upon the earlier to 
occur of its adoption by the Board of Directors or its approval by the 
shareholders of the Company.  It shall continue in effect for a term of ten 
(10) years unless sooner terminated under Section 20 hereof.

    24.  AUTOMATIC TRANSFER TO LOW PRICE OFFERING PERIOD.  To the extent 
permitted by any applicable laws, regulations, or stock exchange rules if the 
Fair Market Value of the Common Stock on any Exercise Date in an Offering 
Period is lower than the Fair Market Value of the Common Stock on the 
Enrollment Date of such Offering Period, then all participants in such 
Offering Period shall be automatically withdrawn from such Offering Period 
immediately after the exercise of their option on such Exercise Date and 
automatically re-enrolled in the immediately following Offering Period as of 
the first day thereof.

                              EXHIBIT A


                    LIVINGSTON ENTERPRISES, INC.

                  1997 EMPLOYEE STOCK PURCHASE PLAN

                       SUBSCRIPTION AGREEMENT



_____ Original Application              Enrollment Date: ___________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)


1.   ___________________________________________________ hereby elects to
     participate in the Livingston Enterprises, Inc.  1997 Employee Stock
     Purchase Plan (the "Employee Stock Purchase Plan") and subscribes to
     purchase shares of the Company's Common Stock in accordance with this
     Subscription Agreement and the Employee Stock Purchase Plan.

2.   I hereby authorize payroll deductions from each paycheck in the amount of
     ____% of my Compensation on each payday (from 1 to _____%) during the
     Offering Period in accordance with the Employee Stock Purchase Plan. 
     (Please note that no fractional percentages are permitted.)

3.   I understand that said payroll deductions shall be accumulated for the
     purchase of shares of Common Stock at the applicable Purchase Price
     determined in accordance with the Employee Stock Purchase Plan.  I
     understand that if I do not withdraw from an Offering Period, any
     accumulated payroll deductions will be used to automatically exercise my
     option.

4.   I have received a copy of the complete Employee Stock Purchase Plan.  I
     understand that my participation in the Employee Stock Purchase Plan is in
     all respects subject to the terms of the Plan.  I understand that my
     ability to exercise the option under this Subscription Agreement is 
     subject to shareholder approval of the Employee Stock Purchase Plan.

5.   Shares purchased for me under the Employee Stock Purchase Plan should be
     issued in the name(s) of (Employee or Employee and Spouse only):
     ______________________________________________.

6.   I understand that if I dispose of any shares received by me pursuant to 
     the Plan within 2 years after the Enrollment Date (the first day of the
     Offering Period during which I purchased such shares) or one year after 
     the Exercise Date, I will be treated for federal income tax purposes as 
     having received ordinary income at the time of such disposition in an 
     amount equal to the

                                      -1-

<PAGE>

     excess of the fair market value of the shares at the time such shares 
     were purchased by me over the price which I paid for the shares.  I 
     HEREBY AGREE TO NOTIFY THE COMPANY IN WRITING WITHIN 30 DAYS AFTER 
     THE DATE OF ANY DISPOSITION OF MY SHARES AND I WILL MAKE ADEQUATE 
     PROVISION FOR FEDERAL, STATE OR OTHER TAX WITHHOLDING OBLIGATIONS, IF 
     ANY, WHICH ARISE UPON THE DISPOSITION OF THE COMMON STOCK.  The Company 
     may, but will not be obligated to, withhold from my compensation the 
     amount necessary to meet any applicable withholding obligation including 
     any withholding necessary to make available to the Company any tax 
     deductions or benefits attributable to sale or early disposition of 
     Common Stock by me. If I dispose of such shares at any time after the 
     expiration of the 2-year and 1-year holding periods, I understand that I 
     will be treated for federal income tax purposes as having received income 
     only at the time of such disposition, and that such income will be taxed 
     as ordinary income only to the extent of an amount equal to the lesser of 
     (1) the excess of the fair market value of the shares at the time of such 
     disposition over the purchase price which I paid for the shares, or 
     (2) 15% of the fair market value of the shares on the first day of the 
     Offering Period.  The remainder of the gain, if any, recognized on such 
     disposition will be taxed as capital gain.

7.   I hereby agree to be bound by the terms of the Employee Stock Purchase
     Plan.  The effectiveness of this Subscription Agreement is dependent upon
     my eligibility to participate in the Employee Stock Purchase Plan.

8.   In the event of my death, I hereby designate the following as my
     beneficiary(ies) to receive all payments and shares due me under the
     Employee Stock Purchase Plan:


NAME:  (Please print)______________________________________________

to pay Base Rent shall be abated for the period of such early occupancy. All 
other terms of this Lease, however, (including but not limited to the 
obligations to pay Lessee's Share of Common Area Operating Expenses and to

period. Any such early possession shall not affect nor advance the Expiration

     3.3 DELAY IN POSSESSION. If for any reason, Lessor cannot deliver 
possession of the Premises to Lessee by the Early Possession Date, if one is 
specified in Paragraph 1.4, or if no Early Possession Date is specified, by 
the Commencement Date, Lessor shall not be subject to any liability therefor, 
nor shall such failure affect the validity of this Lease, or the obligations 
of Lessee hereunder, or extend the term hereof, but in such case, Lessee 
shall not, except as otherwise provided herein, be obligated to pay rent or 
perform any other obligation of Lessee under the terms of this Lease until

cancel this Lease hereunder shall terminate and be of no further force or 
effect.

charges for any period during the term hereof which is for less than one full 
month shall be prorated based upon the actual number of days of the month 
involved. Payment of Base Rent and other charges shall be made to Lessor at 
its address stated herein or to such other persons or at such other addresses 
as Lessor may from time to time designate in writing to Lessee.

     4.2 COMMON AREA OPERATING EXPENSES. Lessee shall pay to Lessor during 
the term hereof, in addition to the Base Rent, Lessee's Share (as specified 
in Paragraph 1.6(b)) of all Common Area Operating Expenses, as hereinafter 
defined, during each calendar year of the term of this Lease, in accordance 
with the following provisions:

         (a)  "COMMON AREA OPERATING EXPENSES" are defined, for purposes of 
this Lease, as all COSTS incurred by Lessor relating to the ownership and 
operation of the Industrial Center, including, BUT NOT LIMITED TO, the 
following:

              (i)  The operation, repair and maintenance, in neat, clean, 
good order and condition, of the following:

                   (aa) The Common Areas, including parking areas, loading 
and unloading areas, trash areas, roadways, sidewalks, walkways, parkways, 
driveways, landscaped areas, striping, bumpers, irrigation systems, Common 
Area lighting facilities, fences and gates, elevators and roof.

                   (bb) Exterior signs and any tenant directories.

                   (cc) Fire detection and sprinkler systems.

              (ii) The cost of water, gas, electricity and telephone to service 
the Common Areas, including pest control and window washing services.

             (iii) Trash disposal, property management and security services 
and the costs of any environmental inspections.

              (iv) Reserves set aside for maintenance and repair of Common
Areas.

               (v) Real Property Taxes (as defined in Paragraph 10.2) to be paid
by Lessor for the Building and the Common Areas under Paragraph 10 hereof, and
any property association dues and expenses levied against the Industrial Center.

              (vi) The cost of the premiums for the insurance policies 
maintained by Lessor under Paragraph 8 hereof.

             (vii) Any deductible portion of an insured loss concerning the 
Building or the Common Areas.

            (viii) Any other services to be provided by Lessor that are 
stated elsewhere in this Lease to be a Common Area Operating Expense.

         (b) Any Common Area Operating Expenses and Real Property Taxes that 
are specifically attributable to the Building or to any other building in the 
Industrial Center or to the operation, repair and maintenance thereof, shall 
be allocated entirely to the Building or to such other building. However, any 
Common Area Operating Expenses and Real Property Taxes that are not 
specifically attributable to the Building or to any other building or to the 
operation, repair and maintenance thereof, shall be equitably allocated by 
Lessor to all buildings in the Industrial Center.

         (c) The inclusion of the improvements, facilities and services set 
forth in Subparagraph 4.2(a) shall not be deemed to impose an obligation upon 
Lessor to either have said improvements or facilities or to provide those 
services unless the Industrial Center already has the same. Lessor already 
provides the services, or Lessor has agreed elsewhere in the Lease to provide 
the same or some of them.

         (d) Lessee's Share of Common Area Operating Expense shall be payable 
by Lessee within ten (10) 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 of Lessee's Share of 
annual Common Area Operating Expense and the same shall be payable monthly or 
quarterly, as Lessor shall designate, during each 12-month period of the 
Lease term on the same day as the Base Rent is due hereunder. Lessor shall 
deliver to Lessee within sixty (60) days after the expiration of each calendar 
year a reasonably detailed statement showing Lessee's Share of the actual 
Common Area Operating Expenses incurred during the preceding year. If Lessee's 
payments under this Paragraph 4.2(d) during said preceding year exceed 
Lessee's Share as indicated on said statement, Lessor shall be credited the 
amount of such over-


                                       -2-

<PAGE>


payment against Lessee's Share of Common Area Operating Expenses next becoming 
due. If Lessee's payments under this Paragraph 4.2(d) during said preceding 
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.

5.  SECURITY DEPOSIT. Lessee shall deposit with Lessor upon Lessee's 
execution hereof the Security Deposit set forth in Paragraph 1.7 as security 
for Lessee's faithful performance of Lessee's obligations under this Lease. 
If Lessee fails to pay Base Rent or other rent or charges due hereunder, or 
otherwise Defaults under this Lease (as defined in Paragraph 13.1), Lessor 
may use, apply or retain all or any portion of said Security Deposit for the 
payment of any amount due Lessor or to reimburse or compensate Lessor for any 
liability, cost, expense, loss or damage (including attorneys' fees) which 
Lessor may suffer or incur by reason thereof. If Lessor uses or applies all 
or any portion of said Security Deposit, Lessee shall within ten (10) days 
after written request therefore deposit monies with Lessor sufficient to 
restore said Security Deposit to the full amount required by this Lease. Any 
time the Base Rent increases during the term of this Lease, Lessee shall, 
upon written request from Lessor, deposit additional monies with Lessor as an 
addition to the Security Deposit so that the total amount of the Security 
Deposit shall at all times bear the same proportion to the then current Base 
Rent as the initial Security Deposit bears to the initial Base Rent set forth 
in Paragraph 1.5. Lessor shall not be required to keep all or any part of the 
Security Deposit separate from its general accounts. Lessor shall, at the 
expiration or earlier termination of the term hereof and after Lessee has 
vacated the Premises, return to Lessee (or, at Lessor's option, to the last 
assignee, if any, or Lessee's interest herein), that portion of the Security 
Deposit not used or applied by Lessor. Unless otherwise expressly agreed in 
writing by Lessor, no part of the Security Deposit shall be considered to be 
held in trust, to bear interest or other increment for its use, or to be 
prepayment for any monies to be paid by Lessee under this Lease.

6.  USE.

     6.1 PERMITTED USE.

         (a) Lessee shall use and occupy the Premises only for the Permitted 
Use set forth in Paragraph 1.6, or any other legal use which is reasonably 
comparable thereto, and for no other purpose. Lessee shall not use or permit 
the use of the Premises in a manner that is unlawful, creates waste or a 
nuisance, or that disturbs owners and/or occupants of, or causes damage to 
the Premises or neighboring premises or properties.

     6.2 HAZARDOUS SUBSTANCES.

         (a) REPORTABLE USES REQUIRE CONSENT. The term "Hazardous Substances" 
as used in this Lease shall mean any product, substance, chemical, material 
or waste whose presence, nature, quantity and/or intensity of existence, use, 
manufacture, disposal, transportation, spill, release or effect, either by 
itself of in combination with other materials expected to be on the Premises, 
is either: (i) potentially injurious to the public health, safety or welfare, 
the environment, or the Premises; (ii) regulated or monitored by any 
governmental authority; or (iii) a basis for potential liability of Lessor to 
any governmental agency or third party under any applicable statute or common 
law theory. Hazardous Substance shall include, but not be limited to, 
hydrocarbons, petroleum, gasoline, crude oil or any products or by-products 
thereof. Lessee shall not engage in any activity in or about the Premises 
which constitutes a Reportable Use (as hereinafter defined) of Hazardous 
Substances without the express prior written consent of Lessor and compliance 
in a timely manner (at Lessee's sole cost and expense) with all Applicable 
Requirements (as defined in Paragraph 6.3). "Reportable Use" shall mean (i) 
the installation or use of any above or below ground storage tank, (ii) the 
generation, possession, storage, use, transportation, or disposal of a 
Hazardous Substance that requires a permit from, or with respect to which a 
report, notice, registration or business plan is required to be filed with, 
any governmental authority, and (iii) the presence in, on or about the 
Premises of a Hazardous Substance with respect to which any Applicable Laws 
require that a notice be given to persons entering or occupying the Premises 
or neighboring properties. Notwithstanding the foregoing, Lessee may, without 
Lessor's prior consent, but upon notice to Lessor and in compliance with all 
Applicable Requirements, use any ordinary and customary materials reasonably 
required to be used by Lessee in the normal course of the Permitted Use, so 
long as such use is not a Reportable Use and does not expose the Premises or 
neighboring properties to any meaningful risk of contamination or damage or 
expose Lessor to any liability therefor. In addition, Lessor may (but 
without any obligation to do so) condition its consent to any Reportable Use 
of any Hazardous Substance by Lessee upon Lessee's giving Lessor such 
additional assurances as Lessor, in its reasonable discretion, deems 
necessary to protect itself, the public, the Premises and the environment 
against damage, contamination or injury and/or liability therefor, including 
but not limited to the installation (and, at Lessor's option, removal on or 
before Lease expiration or earlier termination) of reasonably necessary 
protective modifications to the Premises (such as concrete encasements) 
and/or the deposit of an additional Security Deposit under Paragraph 5 hereof.

         (b) DUTY TO INFORM LESSOR. If Lessee knows, or has reasonable cause 
to believe, that a Hazardous Substance has come to be located in, on, under 
or about the Premises or the Building, other than as previously consented to 
by Lessor, Lessee shall immediately give Lessor written notice thereof, 
together with a copy of any statement, report, notice, registration, 
application, permit, business plan, license, claim, action or proceeding 
given to, or received from, any governmental authority or private party 
concerning the presence, spill, release, discharge of, or exposure to, such 
Hazardous Substance including but not limited to all such documents as may be 
involved in any Reportable Use involving the Premises. Lessee shall not cause 
or permit any Hazardous Substance to be spilled or released in, on, under or 
about the Premises (including, without limitation, through the plumbing or 
sanitary sewer system).

         (c) INDEMNIFICATION. Lessee shall indemnify, protect, defend and 
hold Lessor, its agents, employees, lenders and ground lessor, if any, and 
the Premises, harmless from and against any and all damages, liabilities, 
judgments, costs, claims, liens, expenses, penalties, loss of permits and 
attorneys' and consultants' fees arising out of or involving any Hazardous 
Substance brought onto the Premises by or for Lessee or by anyone under 
Lessee's control. Lessee's obligations under this Paragraph 6.2(c) shall 
include, but not be limited to, the effects of any contamination or injury to 
person, property or the environment created or suffered by Lessee, and the 
cost of investigation (including consultants' and attorneys' fees and 
testing), removal, remediation, restoration and/or abatement thereof, or of 
any contamination therein involved, and shall survive the expiration or 
earlier termination of this Lease. No termination, cancellation or release 
agreement entered into by Lessor and Lessee shall release Lessee from its 
obligations under this Lease with respect to Hazardous Substances, unless 
specifically so agreed by Lessor in writing at the time of such agreement.

     6.3 LESSEE'S COMPLIANCE WITH REQUIREMENTS. Lessee shall, at Lessee's 
sole cost and expense, fully, diligently and in a timely manner, comply with 
all "Applicable Requirements," which term is used in this Lease to mean all 
laws, rules, regulations, ordinances, directives, covenants, easements, and 
restrictions of record, permits, the requirements of any applicable fire 
insurance underwriter or rating bureau, and the recommendations of Lessor's 
engineers and/or consultants, relating in any manner to the Premises 
(including but not limited to matters pertaining to (i) industrial hygiene, 
(ii) environmental conditions on, in, under or about the Premises, including 
soil and groundwater conditions, and (iii) the use, generation, 
manufacture, production, installation, maintenance, removal, transportation, 
storage, spill, or release of any Hazardous Substance), now in effect or 
which may hereafter come into effect. Lessee shall, within five (5) days 
after receipt of Lessor's written request, provide Lessor with copies of all 
documents and information, including but not limited to permits, 
registrations, manifests, applications, reports and certificates, evidencing 
Lessee's compliance with any Applicable Requirements specified by Lessor, and 
shall immediately upon receipt, notify Lessor in writing (with copies of any 
documents involved) of any threatened or actual claim, notice, citation, 
warning, complaint or report pertaining to or involving failure by Lessee or 
the Premises to comply with any Applicable Requirements.

     6.4 INSPECTION - COMPLIANCE WITH LAW. Lessor, Lessor's agents, 
employees, contractors and designated representatives, and the holders of any 
mortgages, deeds of trust or ground leases on the Premises ("Lenders") shall 
have the right to enter the Premises at any time in the case of an emergency, 
and otherwise at reasonable times, upon reasonable notice, for the purpose of 
inspecting the condition of the Premises and for verifying compliance by 
Lessee with this Lease and all Applicable Requirements (as defined in 
Paragraph 6.3), and Lessor shall be entitled to employ experts and/or 
consultants in connection therewith to advise Lessor with respect to Lessee's 
activities, including but not limited to Lessee's installation, operation, 
use, monitoring, maintenance, or removal of any Hazardous Substance on or 
from the Premises. The cost and expenses of any such inspections shall be 
paid by the party requesting same, unless a Default or Breach of this Lease 
by Lessee or a violation of Applicable Requirements or a contamination, 
caused or materially contributed to by Lessee, is found to exist or to be 
imminent, or unless the inspection is requested or ordered by a governmental 
authority as the result of any such existing or imminent violation or 
contamination. In such case, Lessee shall upon request reimburse Lessor or 
Lessor's Lender, as the case may be, for the costs and expenses of such 
inspections.

7.  MAINTENANCE, REPAIRS, UTILITY INSTALLATION, TRADE FIXTURES AND ALTERATIONS.

     7.1 LESSEE'S OBLIGATIONS.

         (a) Subject to the provisions of Paragraphs 2.2 (Condition). 2.3 
(Compliance with Covenants, Restrictions and Building Code), 7.2 (Lessor's 
Obligations), 9 (Damage or Destruction), and 14 (Condemnation), Lessee shall, 
at Lessee's sole cost and expense and at all times, keep the Premises and 
every part thereof in good order, condition and repair (whether or not such 
portion of the Premises requiring repair, or the means of repairing the same, 
are reasonably or readily accessible to Lessee, and whether or not the need 
for such repairs occurs as a result of Lessee's use, any prior use, the 
elements or the age of such portion of the Premises), including, without 
limiting the generality of the foregoing, all equipment or facilities 
specifically serving the Premises, such as plumbing, heating, air 
conditioning, ventilating, electrical, lighting facilities, boilers, fired or 
unfired pressure vessels, fire hose connections if within the Premises, 
fixtures, interior walls, interior surfaces or exterior walls, ceilings, 
floors, windows, doors, plate glass, and skylights, but excluding any items 
which are the responsibility of Lessor pursuant to Paragraph 7.2 below. 
Lessee, in keeping the Premises in good order, condition and repair, shall 
exercise and perform good maintenance practices. Lessee's obligations shall 
include restorations, replacements or renewals when necessary to keep the 
Premises and all improvements thereon or a part thereof in good order, 
condition and state of repair.

         (b) Lessee shall, at Lessee's sole cost and expense, procure and 
maintain a contract, with copies to Lessor, in customary form and substance 
for and with a contractor specializing and experienced in the inspection, 
maintenance and service of the heating, air conditioning and ventilation 
system for the Premises. However, Lessor reserves the right, upon notice to 
Lessee, to procure and maintain the contract for the heating, air 
conditioning and ventilating systems and if Lessor so elects, Lessee shall 
reimburse Lessor, upon demand, for the cost thereof.

         (c) If Lessee fails to perform Lessee's obligations under this 
Paragraph 7.1, Lessor may enter upon the Premises after ten (10) days prior 
written notice to Lessee (except in the case of an emergency, in which case 
no notice shall be required), perform such obligations on Lessee's behalf, 
and put the Premises in good order, condition and repair, in accordance with 
Paragraph 13.2 below.

     7.2 LESSOR'S OBLIGATIONS. Subject to the provisions of Paragraphs 2.2 
(Condition), 2.3 (Compliance with Covenants, Restrictions and Building Code), 
4.2 (Common Area Operating Expenses), 6 (Use), 7.1 (Lessee's Obligations), 9 
(Damage or Destruction) and 14 (Condemnation), Lessor, subject to 
reimbursement pursuant to Paragraph 4.2, shall keep in good order, condition 
and repair the foundations, exterior walls, structural condition of interior 
bearing walls, exterior roof, fire sprinkler and/or standpipe or hose (if 
located in the Common Areas) or other automatic fire extinguishing system 
including fire alarm and/or smoke


                                       -3-



<PAGE>

detection systems and equipment, fire hydrants, parking lots, walkways, 
parkways, driveways, landscaping, fences, signs and utility systems serving 
the Common Areas and all parts thereof, as well as providing the services for 
which there is a Common Area Operating Expense pursuant to Paragraph 4.2. 
Lessor shall not be obligated to paint the exterior or interior surfaces of 
exterior walls nor shall Lessor be obligated to maintain, repair or replace 
windows, doors or plate glass of the Premises. Lessee expressly waives the 
benefit 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 Building, Industrial 
Center or Common Areas in good order, condition and repair.

    7.3  UTILITY INSTALLATIONS, TRADE FIXTURES, ALTERATIONS.

         (a)  DEFINITIONS; CONSENT REQUIRED.  The term "Utility Installations" 
is used in this Lease to refer to all air lines, power panels, electrical 
distribution, security, fire protection systems, communications systems, 
lighting fixtures, heating, ventilating and air conditioning equipment, 
plumbing, and fencing in, on or about the Premises. The term "Trade Fixtures" 
shall mean Lessee's machinery and equipment which can be removed without 
doing material damage to the Premises. The term "Alterations" shall mean any 
modification of the improvements on the Premises which are provided by Lessor 
under the terms of this Lease, other than Utility Installations or Trade 
Fixtures. "Lessee-Owned Alterations and/or Utility Installations" are defined 
as Alterations and/or Utility Installations made by Lessee that are not yet 
owned by Lessor pursuant to Paragraph 7.4(a). Lessee shall not make nor cause 
to be made any Alterations or Utility Installations in, on, under or about 
the Premises without Lessor's prior written consent. Lessee may, however, 
make non-structural Utility Installations to the interior of the Premises 
(excluding the roof) without Lessor's consent but upon notice to Lessor, so 
long as they are not visible from the outside of the Premises, do not involve 
puncturing, relocating or removing the roof or any existing walks, or 
changing or interfering with the fire sprinkler or fire detection systems and 
the cumulative cost thereof during the term of this Lease as extended does 
not exceed $2,500.00.

         (b)  CONSENT.  Any Alterations or Utility Installations that Lessee 
shall desire to make and which require the consent of the Lessor shall be 
presented to Lessor in written form with detailed plans. All consents given 
by Lessor, whether by virtue of Paragraph 7.3(a) or by subsequent specific 
consent, shall be deemed conditioned upon: (i) Lessee's acquiring all 
applicable permits required by governmental authorities; (ii) the furnishing 
of copies of such permits together with a copy of the plans and 
specifications for the Alteration or Utility Installation to Lessor prior to 
commencement of the work thereon; and (iii) the compliance by Lessee with all 
conditions of said permits in a prompt and expeditious manner. Any 
Alterations or Utility Installations by Lessee during the term of this Lease 
shall be done in a good and workmanlike manner, with good and sufficient 
materials, and be in compliance with all Applicable Requirements. Lessee 
shall promptly upon completion thereof furnish Lessor with as-built plans and 
specifications therefor. Lessee may, (but without obligation to do so) 
condition its consent to any requested Alteration or Utility Installation 
that costs $2,500.00 or more upon Lessee's providing Lessor with a lien and 
completion bond in an amount equal to one and one-half times the estimated 
cost of such Alteration or Utility Installation.

         (c)  LIEN PROTECTION.  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 on the Premises, which claims are or may be secured by any 
mechanic's or materialmen's lien against the Premises or any interest 
therein. Lessee shall give Lessor not less than ten (10) days' notice prior 
to the commencement of any work in, on, or about the Premises, and Lessor 
shall have the right to post notices of non-responsibility in or on the 
Premises 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 and protect itself, Lessor and the Premises 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. If 
Lessor shall require, Lessee shall furnish to Lessor a surety bond 
satisfactory to Lessor in an amount equal to one and one-half times the 
amount of such contested lien claim or demand, indemnifying Lessor against 
liability for the same, as required by law for the holding of the Premises 
free from the effect of such lien or claim. In addition, Lessor may require 
Lessee to pay Lessor's attorneys' fees and costs in participating in such 
action if Lessor shall decide it is to its best interest to do so.

    7.4  OWNERSHIP, REMOVAL, SURRENDER, AND RESTORATION.

         (a)  OWNERSHIP.  Subject to Lessor's right to require their removal 
and to cause Lessee to become the owner thereof as hereinafter provided in 
this Paragraph 7.4, all Alterations and Utility Installations made to the 
Premises by Lessee shall be the property of and owned by Lessee, but 
considered a part of the Premises. Lessor may, at any time and at its option, 
elect in writing to Lessee to be the owner of all or any specified part of the 
Lessee-Owned Alterations and Utility Installations. Unless otherwise 
instructed per Subparagraph 7.4(b) hereof, all Lessee-Owned Alterations and 
Utility Installations shall, at the expiration or earlier termination of this 
Lease, become the property of Lessor and remain upon the Premises and be 
surrendered with the Premises by Lessee.

         (b)  REMOVAL.  Unless otherwise agreed in writing, Lessor may require 
that any or all Lessee-Owned Alterations or Utility Installations be removed 
by the expiration or earlier termination of this Lease, notwithstanding that 
their installation may have been consented to by Lessor. Lessor may require 
the removal at any time of all or any part of any Alterations or Utility 
Installations made without the required consent of Lessor.

         (c)  SURRENDER/RESTORATION.  Lessee shall surrender the Premises by 
the end of the last day of the Lease term or any earlier termination date, 
clean and free of debris and in good operating order, condition and state of 
repair, ordinary wear and tear excepted. Ordinary wear and tear shall not 
include any damage or deterioration that would have been prevented by good 
maintenance practice or by Lessee performing all of its obligations under 
this Lease. Except as otherwise agreed or specified herein, the Premises, as 
surrendered, shall include the Alterations and Utility Installations. The 
obligation of Lessee shall include the repair of any damage occasioned by the 
Installation, maintenance or removal of Lessee's Trade Fixtures, furnishings, 
equipment, and Lessee-Owned Alterations and Utility Installations, as well as 
the removal of any storage tank installed by or for Lessee, and the removal, 
replacement, or remediation of any soil, material or ground water 
contaminated by Lessee, all as may then be required by Applicable 
Requirements and/or good practice. Lessee's Trade Fixtures shall remain the 
Property of Lessee and shall be removed by Lessee subject to its obligation 
to repair and restore the Premises per this Lease.

8.  INSURANCE; INDEMNITY

    8.1  PAYMENT OF PREMIUMS.  The cost of the premiums for the insurance 
policies maintained by Lessor under this Paragraph 8 shall be a Common Area 
Operating Expense pursuant to Paragraph 4.2 hereof. Premiums for policy 
periods commencing prior to, or extending beyond, the term of this Lease 
shall be pro-rated to coincide with the corresponding Commencement Date or 
Expiration Date.

    8.2  LIABILITY INSURANCE.

         (a)  CARRIED BY LESSEE.  Lessee shall obtain and keep in force 
during the term of this Lease a Commercial General Liability policy of 
insurance protecting Lessee, Lessor and any Lender(s) whose names have been 
provided to Lessee in writing (as additional insureds) against claims for 
bodily injury, personal injury and property damage based upon, involving or 
arising out of the ownership, use, occupancy or maintenance of the Premises 
and all areas appurtenant thereto. Such insurance shall be on an occurrence 
basis providing single unit coverage in an amount not less than $2,000,000 
per occurrence with an "Additional Insured-Managers or Lessors of Premises" 
endorsement and contain the "Amendment of the Pollution Exclusion" 
endorsement for damage caused by heat, smoke or fumes from a hostile fire. 
The policy shall not contain any intra-insured exclusions as between insured 
persons or organizations, but shall include coverage for liability assumed 
under this Lease as an "insured contract" for the performance of Lessee's 
indemnity obligations under this Lease. The limits of said insurance required 
by this Lease or as carried by Lessee shall not, however, limit the liability 
of Lessee nor relieve Lessee of any obligation hereunder. All insurance to be 
carried by Lessee shall be primary to and not contributory with any similar 
insurance carried by Lessor, whose insurance shall be considered excess 
insurance only.

         (b)  CARRIED BY LESSOR.  Lessor shall also maintain liability 
insurance described in Paragraph 8.2(a) above, in addition to and not in lieu 
of, the insurance required to be maintained by Lessee. Lessee shall not be 
named as an additional insured therein.

     8.3  PROPERTY INSURANCE-BUILDING, IMPROVEMENTS AND RENTAL VALUE.

         (a)  BUILDING AND IMPROVEMENTS.  Lessor shall obtain and keep in 
force during the term of this Lease a policy or policies in the name of 
Lessor, with loss payable to Lessor and to any Lender(s), insuring against 
loss or damage to the Premises. Such insurance shall be for full replacement 
cost, as the same shall exist from time to time, or the amount required by 
any Lender(s), but in no event more than the commercially reasonable and 
available insurable value thereof if, by reason of the unique nature or age 
of the improvements involved, such latter amount is less than full 
replacement cost. Lessee-Owned Alterations and Utility Installations, Trade 
Fixtures and Lessee's personal property shall be insured by Lessee pursuant 
to Paragraph 8.4. If the coverage is available and commercially appropriate, 
Lessor's policy or policies shall insure against all risks of direct physical 
loss or damage (except the perils of flood unless required by a Lender), 
including coverage for any additional costs resulting from debris removal and 
reasonable amounts of coverage for the enforcement of any ordinance or law 
regulating the reconstruction or replacement of any undamaged sections of the 
Building required to be demolished or removed by reason of the enforcement of 
any building, zoning, safety or land use laws as the result of a covered 
loss, but not including plate glass insurance. Said policy or policies shall 
also contain an agreed valuation provision in lieu of any co-insurance 
clause, waiver of subrogation, and inflation guard protection causing an 
increase in the annual property insurance coverage amount by a factor of not 
less than the adjusted U.S. Department of Labor Consumer Price Index for All 
Urban Consumers for the city nearest to where the Premises are located.

         (b)  RENTAL VALUE.  Lessor shall also obtain and keep in force during 
the term of this Lease a policy or policies in the name of Lessor, with loss 
payable to Lessor and any Lender(s), insuring the loss of the full rental and 
other charges payable by all lessees of the Building to Lessor for one year 
(including all Real Property Taxes, insurance costs, all Common Area 
Operating Expenses and any scheduled rental increases). Said insurance may 
provide that in the event the Lease is terminated by reason of an insured 
loss, the period of indemnity for such coverage shall be extended beyond the 
date of the completion of repairs or replacement of the Premises, to provide 
for one full year's loss of rental revenues from the date of any such loss. 
Said insurance shall contain an agreed valuation provision in lieu of any 
co-insurance clause, and the amount of coverage shall be adjusted annually to 
reflect the projected rental income. Real Property Taxes, insurance premium 
costs and other expenses, if any, otherwise payable, for the next 12-month 
period. Common Area Operating Expenses shall include any deductible amount in 
the event of such loss.

         (c)  ADJACENT PREMISES.  Lessee shall pay for any increase in the 
premiums for the property insurance of the Building and for the Common Areas 
or other buildings in the Industrial Center if said increase is caused by 
Lessee's acts, omissions, use or occupancy of the Premises.

         (d)  LESSEE'S IMPROVEMENTS.  Since Lessor is the Insuring Party, 
Lessor shall not be required to insure Lessee-Owned Alterations and Utility 
Installations unless the item in question has become the property of Lessor 
under the terms of this Lease.

    8.4  LESSEE'S PROPERTY INSURANCE.  Subject to the requirements of 
Paragraph 8.5, Lessee at its cost shall either by separate policy or, at 
Lessor's option, by endorsement to a policy already carried, maintain 
insurance coverage on all of Lessee's personal property, Trade Fixtures and 
Lessee-Owned Alterations and Utility Installations in, on, or about the 
Premises similar in coverage to that carried by Lessor as the Insuring Party 
under Paragraph 8.3(a). Such insurance shall be full replacement cost coverage 
with a deductible not to exceed $1,000 per occurrence. The proceeds from any 
such insurance shall be used by Lessee for the replacement of personal 
property and the restoration of Trade Fixtures and Lessee-Owned Alterations 
and Utility Installations. Upon request from Lessor, Lessee shall provide 
Lessor with written evidence that such insurance is in force.

    8.5  INSURANCE POLICIES.  Insurance required hereunder shall be in 
companies duly licensed to transact business in the state where the Premises 
are located and maintaining during the policy term a "General Policyholders 
Rating" of at least B+, V, or such other rating as may be required by a 
Lender as set forth in the most current issue of "Best's Insurance Guide." 
Lessee shall not do or permit to be done anything which shall invalidate the 
insurance policies referred to in

                                       4
<PAGE>

this Paragraph 8. Lessee shall cause to be delivered to Lessor, within seven 
(7) days after the earlier of the Early Possession Date or the Commencement 
Date, certified copies of, or certificates evidencing the existence and 
amounts of, the insurance required under Paragraph 8.2(a) and 8.4. No such 
policy shall be cancellable or subject to 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 evidence 
of renewals or "insurance binders" evidencing renewal thereof, or Lessor may 
order such insurance and charge the cost thereof to Lessee, which amount 
shall be payable by Lessee to Lessor upon demand.

    8.6  WAIVER OF SUBROGATION.  Without affecting any other rights or 
remedies, Lessee and Lessor each hereby release and relieve the other, and 
waive their entire right to recover damages (whether in contract or in tort) 
against the other, for loss or damage to their property arising out of or 
incident to the perils required to be insured against under Paragraph 8. The 
effect of such releases and waivers of the right to recover damages shall not 
be limited by the amount of insurance carried or required, or by any 
deductibles applicable thereto. Lessor and Lessee agree to have their 
respective insurance companies issuing property damage insurance waive any 
right to subrogation that such companies may have against Lessor or Lessee, 
as the case may be, so long as the insurance is not invalidated thereby.

    8.7  INDEMNITY.  Except for Lessor's negligence and/or breach of express 
warranties, Lessee shall indemnify, protect, defend and hold harmless the 
Premises, Lessor and its agents, Lessor's master or ground lessor, partners 
and Lenders, from and against any and all claims, loss of rents and/or 
damages, costs, liens, judgments, penalties, loss of permits, attorneys' and 
consultants' fees, expenses and/or liabilities arising out of, involving, or 
in connection with, the occupancy of the Premises by Lessee, the conduct of 
Lessee's business, any act, omission or neglect of Lessee, its agents, 
contractors, employees or invitees, and out of any Default or Breach by 
Lessee in the performance in a timely manner of any obligation on Lessee's 
part to be performed under this Lease. The foregoing shall include, but not 
be limited to, the defense or pursuit of any claim or any action or 
proceeding involved therein, and whether or not (in the case of claims made 
against Lessor) litigated and/or reduced to judgment. In case any action or 
proceeding be brought against Lessor by reason of any of the foregoing 
matters, 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.

    8.8  EXEMPTION OF LESSOR FROM LIABILITY.  Lessor shall not be liable for 
injury or damage to the person or goods, wares, merchandise or other property 
of Lessee, Lessee's employees, contractors, invitees, customers, or any other 
person in or about the Premises, whether such damage or injury is caused by 
or results from fire, steam, electricity, gas, water or rain, or from the 
breakage, leakage, obstruction or other defects of pipes, fire sprinklers, 
wires, appliances, plumbing, air conditioning or lighting fixtures, or from 
any other cause, whether said injury or damage results from conditions 
arising upon the Premises or upon other portions of the Building of which the 
Premises are a part, from other sources or places, and regardless of whether 
the cause of such damage or injury or the means of repairing the same is 
accessible or not. Lessor shall not be liable for any damages arising from 
any act or neglect of any other lessee of Lessor nor from the failure by 
Lessor to enforce the provisions of any other lease in the Industrial Center. 
Notwithstanding Lessor's negligence or breach of this Lease, Lessor shall 
under no circumstances be liable for injury to Lessee's business or for any 
loss of income or profit therefrom.

9.  DAMAGE OR DESTRUCTION.

    9.1  DEFINITIONS.

         (a)  "PREMISES PARTIAL DAMAGE" shall mean damage or destruction to 
the Premises, other than Lessee-Owned Alterations and Utility Installations, 
the repair cost of which damage or destruction is less than fifty percent 
(50%) of the then Replacement Cost (as defined in Paragraph 9.1(d)) of the 
Premises (excluding Lessee-Owned Alterations and Utility Installations and 
Trade Fixtures) immediately prior to such damage or destruction.

         (b)  "PREMISES TOTAL DESTRUCTION" shall mean damage or destruction 
to the Premises, other than Lessee-Owned Alterations and Utility 
Installations, the repair cost of which damage or destruction is fifty 
percent (50%) or more of the then Replacement Cost of the Premises (excluding 
Lessee-Owned Alterations and Utility Installations and Trade Fixtures) 
immediately prior to such damage or destruction. In addition, damage or 
destruction to the Building, other than Lessee-Owned Alterations and Utility 
Installations and Trade Fixtures of any lessees of the Building, the cost of 
which damage or destruction is fifty percent (50%) or more of the then 
Replacement Cost (excluding Lessee-Owned Alterations and Utility 
Installations and Trade Fixtures of any lessees of the Building) of the 
Building shall, at the option of Lessor, be deemed to be Premises Total 
Destruction.

         (c)  "INSURED LOSS" shall mean damage or destruction to the 
Premises, other than Lessee-Owned Alterations and Utility Installations and 
Trade Fixtures, which was caused by an event required to be covered by the 
insurance described in Paragraph 8.3(a) irrespective of any deductible 
amounts or coverage limits involved.

         (d)  "REPLACEMENT COST" shall mean the cost to repair or rebuild the 
improvements owned by Lessor at the time of the occurrence to their condition 
existing immediately prior thereto, including demolition, debris removal and 
upgrading required by the operation of applicable building codes, ordinances 
or laws, and without deduction for depreciation.

         (e)  "HAZARDOUS SUBSTANCE CONDITION" shall mean the occurrence or 
discovery of a condition involving the presence of, or a contamination by, a 
Hazardous Substance as defined in Paragraph 6.2(a), in, on, or under the 
Premises.

    9.2  PREMISES PARTIAL DAMAGE - INSURED LOSS.  If Premises Partial Damage 
that is an Insured Loss occurs, then Lessor shall, at Lessor's expense, 
repair such damage (but not Lessee's Trade Fixtures or Lessee-Owned 
Alterations and Utility Installations) as soon as reasonably possible and 
this Lease shall continue in full force and effect. In the event, however, 
that there is a shortage of insurance proceeds and such shortage is due to 
the fact that, by reason of the unique nature of the improvements in the 
Premises, full replacement cost insurance coverage was not commercially 
reasonable and available. Lessor shall have no obligation to pay for the 
shortage in insurance proceeds or to fully restore the unique aspects of the 
Premises unless Lessee provides Lessor with the funds to cover same, or 
adequate assurance thereof, within ten (10) days following receipt of written 
notice of such shortage and request therefor. If Lessor receives said funds 
or adequate assurance thereof within said ten (10) day period, Lessor shall 
complete them as soon as reasonably possible and this Lease shall remain in 
full force and effect. If Lessor does not receive such funds or assurance 
within said period, Lessor may nevertheless elect by written notice to Lessee 
within ten (10) days thereafter to make such restoration and repair as is 
commercially reasonable with Lessor paying any shortage in proceeds, in which 
case this Lease shall remain in full force and effect. If Lessor does not 
receive such funds or assurance within such ten (10) day period, and if 
Lessor does not so elect to restore and repair, then this Lease shall 
terminate sixty (60) days following the occurrence of the damage or 
destruction. Unless otherwise agreed, Lessee shall in no event have any right 
to reimbursement from Lessor for any funds contributed by Lessee to repair 
any such damage or destruction. Premises Partial Damage due to flood or 
earthquake shall be subject to Paragraph 9.3 rather than Paragraph 9.2, 
notwithstanding that there may be some insurance coverage, but the net 
proceeds of any such insurance shall be made available for the repairs if 
made by either Party.

    9.3  PARTIAL DAMAGE - UNINSURED LOSS.  If Premises Partial Damage that is 
not an Insured Loss occurs, unless caused by a negligent or willful act of 
Lessee (in which event Lessee shall make the repairs at Lessee's expense and 
this Lease shall continue in full force and effect), 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) give written notice to Lessee within thirty (30) days after 
receipt by Lessor of knowledge of the occurrence of such damage of Lessor's 
desire to terminate this Lease as of the date sixty (60) days following the 
date of such notice. In the event Lessor elects to give such notice of 
Lessor's intention to terminate this Lease, Lessee shall have the right 
within ten (10) days after the receipt of such notice to give written notice 
to Lessor of Lessee's commitment to pay for the repair of such damage totally 
at Lessee's expense and without reimbursement from Lessor. Lessee shall 
provide Lessor with the required funds or satisfactory assurance thereof 
within thirty (30) days following such commitment from Lessee. In such event 
this Lease shall continue in full force and effect, and Lessor shall proceed 
to make such repairs as soon as reasonably possible after the required funds 
are available. If Lessee does not give such notice and provide the funds or 
assurance thereof within the times specified above, this Lease shall 
terminate as of the date specified in Lessor's notice of termination.

    9.4  TOTAL DESTRUCTION.  Notwithstanding any other provision hereof, if 
Premises Total Destruction occurs (including any destruction required by any 
authorized public authority) this Lease shall terminate sixty (60) days 
following the date of such Premises Total Destruction, whether or not the 
damage or destruction is an Insured Loss or was caused by a negligent or 
willful act of Lessee. In the event, however, that the damage or destruction 
was caused by Lessee, Lessor shall have the right to recover Lessor's damages 
from Lessee except as released and waived in Paragraph 9.7.

    9.5  DAMAGE NEAR END OF TERM.  If at any time during the last six (6) 
months of the term of this Lease there is damage for which the cost to repair 
exceeds one month's Base Rent, whether or not an Insured Loss, Lessor may, at 
Lessor's option, terminate this Lease effective sixty (60) days following the 
date of occurrence of such damage by giving written notice to Lessee of 
Lessor's election to do so within thirty (30) days after the date of 
occurrence of such damage. Provided, however, if Lessee at that time has an 
exercisable option to extend this Lease or to purchase the Premises, then 
Lessee may preserve this Lease by (a) exercising such option, and 
(b) providing Lessor with any shortage in insurance proceeds (or adequate 
assurance thereof) needed to make the repairs on or before the earlier of 
(i) the date which is ten (10) days after Lessee's receipt of Lessor's 
written notice purporting to terminate this Lease, or (ii) the day prior to 
the date upon which such option expires. If Lessee duly exercises such option 
during such period and provides Lessor with funds (or adequate assurance 
thereof) to cover any shortage in insurance proceeds, Lessor shall, at 
Lessor's expense repair such damage as soon as reasonably possible and this 
Lease shall continue in full force and effect. If Lessee fails to exercise 
such option and provide such funds or assurance during such period, then this 
Lease shall terminate as of the date set forth in the first sentence of this 
Paragraph 9.5.

    9.6  ABATEMENT OF RENT; LESSEE'S REMEDIES.

         (a)  In the event of (i) Premises Partial Damage or (ii) Hazardous 
Substance Condition for which Lessee is not legally responsible, the Base 
Rent, Common Area Operating Expenses and other charges, if any, payable by 
Lessee hereunder for the period during which such damage or condition, its 
repair, remediation or restoration continues, shall be abated in proportion 
to the degree to which Lessee's use of the Premises is impaired, but not 
in excess of proceeds from insurance required to be carried under 
Paragraph 8.3(b). Except for abatement of Base Rent, Common Area Operating 
Expenses and other charges, if any, as aforesaid, all other obligations of 
Lessee hereunder shall be performed by Lessee, and Lessee shall have no claim 
against Lessor for any damage suffered by reason of any such damage, 
destruction, repair, remediation or restoration.

         (b)  If Lessor shall be obligated to repair or restore the Premises 
under the provisions of this Paragraph 9 and shall not commence, in a 
substantial and meaningful way, the repair or restoration of the Premises 
within ninety (90) days after such obligation shall accrue. Lessee may, at 
any time prior to the commencement of such repair or restoration, give 
written notice to Lessor and to any Lenders of which Lessee has actual notice 
of Lessee's election to terminate this Lease on a date not less than sixty 
(60) days following the giving of such notice. If Lessee gives such notice to 
Lessor and such Lenders and such repair or restoration is not commenced 
within thirty (30) days after receipt of such notice, this Lease shall 
terminate as of the date specified in said notice. If Lessor or a Lender 
commences the repair or restoration of the Premises within thirty (30) days 
after the receipt of such notice, this Lease shall continue in full force and 
effect. "COMMENCE" as used in this Paragraph 9.6 shall mean either the 
unconditional authorization of the preparation of the required plans, or the 
beginning of the actual work on the Premises, whichever occurs first.

    9.7  HAZARDOUS SUBSTANCE CONDITIONS.  If a Hazardous Substance Condition 
occurs, unless Lessee is legally responsible therefor (in which case Lessee 
shall make the investigation and remediation thereof required by Applicable 
Requirements and this Lease shall continue in full force and effect, but 
subject

                                       5
<PAGE>

to Lessor's rights under Paragraph 6.2(c) and Paragraph 13), Lessor may at 
Lessor's option either (i) investigate and remediate such Hazardous Substance 
Condition, if required, as soon as reasonably possible at Lessor's expense, 
in which event this Lease shall continue in full force and effect, or (ii) if 
the estimated cost to investigate and remediate such condition exceeds twelve 
(12) times the then monthly Base Rent or $100,000 whichever is greater, give 
written notice to Lessee within thirty (30) days after receipt by Lessor of 
knowledge of the occurrence of such Hazardous Substance Condition of Lessor's 
desire to terminate this Lease as of the date sixty (60) days following the 
date of such notice. In the event Lessor elects to give such notice of 
Lessor's intention to terminate this Lease, Lessee shall have the right 
within ten (10) days after the receipt of such notice to give written notice 
to Lessor of Lessee's commitment to pay for the excess costs of (a) 
investigation and remediation of such Hazardous Substance Condition to the 
extent required by Applicable Requirements, over (b) an amount equal to 
twelve (12) times the then monthly Base Rent or $100,000, whichever is 
greater. Lessee shall provide Lessor with the funds required of Lessee or 
satisfactory assurance thereof within thirty (30) days following said 
commitment by Lessee. In such event this Lease shall continue in full force 
and effect, and Lessor shall proceed to make such investigation and 
remediation as soon as reasonably possible after the required funds are 
available. If Lessee does not give such notice and provide the required funds 
or assurance thereof within the time period specified above, this Lease shall 
terminate as of the date specified in Lessor's notice of termination.

     9.8  TERMINATION - ADVANCE PAYMENTS. Upon termination of this Lease 
pursuant to this Paragraph 9, Lessor shall return to Lessee any advance 
payment made by Lessee to Leesor and so much of Lessee's Security Deposit as 
has not been, or is not then required to be, used by Lessor under the terms 
of this Lease.

     9.9  WAIVER OF STATUTES. Lessor and Lessee agree that the terms of this 
Lease shall govern the effect of any damage to or destruction of the Premises 
and the Building with respect to the termination of this Lease and hereby 
waive the provisions of any present or future statute to the extent it is 
inconsistent herewith.

10.  REAL PROPERTY TAXES.

     10.1  PAYMENT OF TAXES. Lessor shall pay the Real Property Taxes, as 
defined in Paragraph 10.2, applicable to the Industrial Center, and except as 
otherwise provided in Paragraph 10.3, any such amounts shall be included in 
the calculation of Common Area Operating Expenses in accordance with the 
provisions of Paragraph 4.2.

     10.2  REAL PROPERTY TAX DEFINITION. As used herein, the term "Real 
Property Taxes" 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 upon the Industrial Center by any 
authority having the direct or indirect power to tax, including any city, 
state or federal government, or any school, agricultural, sanitary, fire, 
street, drainage, or other improvement district thereof, levied against any 
legal or equitable interest of Lessor in the Industrial Center or any portion 
thereof, Lessor's right to rent or other income therefrom, and/or Lessor's 
business of leasing the Premises. The term "Real Property Taxes" shall also 
include any tax, fee, levy, assessment or charge, or any increase therein, 
imposed by reason of events occurring, or changes in Applicable Law taking 
effect, during the term of this Lease, including but not limited to a change 
in the ownership of the Industrial Center or in the improvements thereon, the 
execution of this Lease, or any modification, amendment or transfer thereof, 
and whether or not contemplated by the Parties. In calculating Real Property 
Taxes for any calendar year, the Real Property Taxes for any real estate tax 
year shall be included in the calculation of Real Property Taxes for such 
calendar year based upon the number of days which such calendar year and tax 
year have in common.

     10.3  ADDITIONAL IMPROVEMENTS. Common Area Operating Expenses shall not 
include Real Property Taxes specified in the tax assessor's records and work 
sheets as being caused by additional improvements placed upon the Industrial 
Center by other lessees or by Lessor for the exclusive enjoyment of such 
other lessees. Notwithstanding Paragraph 10.1 hereof, Lessee shall, however, 
pay to Lessor at the time Common Area Operating Expenses are payable under 
Paragraph 4.2, the entirety of any increase in Real Property Taxes if 
assessed solely by reason of Alterations, Trade Fixtures or Utility 
Installations placed upon the Premises by Lessee or at Lessee's request.

     10.4  JOINT ASSESSMENT. If the Building is not separately assessed, Real 
Property Taxes allocated to the Building shall be an equitable proportion of 
the Real Property Taxes for all of the land and improvements included within 
the tax parcel assessed, such proportion to be determined by Lessor from the 
respective valuations assigned in the assessor's work sheets or such other 
information as may be reasonably available. Lessor's reasonable determination 
thereof, in good faith, shall be conclusive.

     10.5  LESSEE'S PROPERTY TAXES. Lessee shall pay prior to delinquency all 
taxes assessed against and levied upon Lessee-Owned Alternations and Utility 
Installations. Trade Fixtures, furnishings, equipment and all personal 
property of Lessee contained in the Premises or stored within the Industrial 
Center. When possible, Lessee shall cause its Lessee-Owned Alterations and 
Utility Installations, Trade Fixtures, furnishings, equipment and all other 
personal property to be assessed and billed separately from the real property 
of Lessor. If any of Lessee's said property shall be assessed with Lessor's 
real property, Lessee shall pay Lessor the taxes attributable to Lessee's 
property within ten (10) days after receipt of a written statement setting 
forth the taxes applicable to Lessee's property.

11.  UTILITIES. Lessee shall pay directly for all utilities and services 
supplied to the Premises, including but not limited to electricity, 
telephone, security, gas and cleaning of the Premises, together with any 
taxes thereon. If any such utilities or services are not separately metered to 
the Premises or separately billed to the Premises, Lessee shall pay to Lessor 
a reasonable proportion to be determined by Lessor of all such charges 
jointly metered or billed with other premises in the Building, in the manner 
and within the time periods set forth in Paragraph 4.2(d).

12.  ASSIGNMENT AND SUBLETTING.

     12.1  LESSOR'S CONSENT REQUIRED.

           (a) Lessee shall not voluntarily or by operation of law assign, 
transfer, mortgage or otherwise transfer or encumber (collectively, "assign") 
or sublet all or any part of Lessee's interest in this Lease or in the 
Premises without Lessor's prior written consent given under and subject to 
the terms of Paragraph 36.

           (b) A change in the control of Lessee shall constitute an 
assignment requiring Lessor's consent. The transfer, on a cumulative basis, 
of twenty-five percent (25%) or more of the voting control of Lessee shall 
constitute a change in control for this purpose.* REFER TO PARAGRAPH 59 BELOW.

           (c) The involvement of Lessee or its assets in any transaction, or 
series of transactions (by way of merger, sale, acquisition, financing, 
refinancing, transfer, leveraged buy-out or otherwise), whether or not a 
formal assignment or hypothecation of this Lease or Lessee's assets occurs, 
which results or will result in a reduction of the Net Worth of Lessee, as 
hereinafter defined, by an amount equal to or greater than twenty-five 
percent (25%) of such Net Worth of Lessee as it was represented to Lessor at 
the time of full execution and delivery of this Lease or at the time of the 
most recent assignment to which Lessor has consented, or as it exists 
immediately prior to said transaction or transactions constituting such 
reduction, at whichever time said Net Worth of Lessee was or is greater, 
shall be considered an assignment of this Lease by Lessee to which Lessor may 
reasonably withhold its consent. "Net Worth of Lessee" for purposes of this 
Lease shall be the net worth of Lessee (excluding any Guarantors) established 
under generally accepted accounting principles consistently applied.

           (d) An assignment or subletting of Lessee's interest in this Lease 
without Lessor's specific prior written consent shall, at Lessor's option, be 
a Default curable after notice per Paragraph 13.1, or a non-curable Breach 
without the necessity of any notice and grace period. If Lessor elects to 
treat such unconsented to assignment or subletting as a non-curable Breach, 
Lessor shall have the right to either: (i) terminate this Lease, or (ii) upon 
thirty (30) days' written notice ("Lessor's Notice"), increase the monthly 
Base Rent for the Premises to the greater of the then fair market rental 
value of the Premises, as reasonably determined by Lessor, or one hundred ten 
percent (110%) of the Base Rent then in effect. Pending determination of the 
new fair market rental value, if disputed by Lessee, Lessee shall pay the 
amount set forth in Lessor's Notice, with any overpayment credited against 
the next installment(s) of Base Rent coming due, and any underpayment for the 
period retroactively to the effective date of the adjustment being due and 
payable immediately upon the determination thereof. Further, in the event of 
such Breach and rental adjustment, (i) the purchase price of any option to 
purchase the Premises held by Lessee shall be subject to similar adjustment 
to the then fair market value as reasonably determined by Lessor (without the 
Lease being considered an encumbrance or any deduction for depreciation or 
obsolescence, and considering the Premises at its highest and best use and in 
good condition) or one hundred ten percent (110%) of the price previously in 
effect, (ii) any index-oriented rental or price adjustment formulas contained 
in this Lease shall be adjusted to require that the base index be determined 
with reference to the index applicable to the time of such adjustment, and 
(iii) any fixed rental adjustments scheduled during the reminder of the Lease 
term shall be increased in the same ratio as the new rental bears to the Base 
Rent in effect immediately prior to the adjustment specified in Lessor's 
Notice.

           (e) Lessee's remedy for any breach of this Paragraph 12.1 by 
Lessor shall be limited to compensatory damages and/or injunctive relief.

     12.2  TERMS AND CONDITIONS APPLICABLE TO ASSIGNMENT AND SUBLETTING.

           (a) Regardless of Lessor's consent, any assignment or subletting 
shall not (i) be effective without the express written assumption by such 
assignee or sublessee of the obligations of Lessee under this Lease, (ii) 
release Lessee of any obligations hereunder, nor (iii) after the primary 
liability of Lessee for the payment of Base Rent and other sums due Lessor 
hereunder or for the performance of any other obligations to be performed by 
Lessee under this Lease.

           (b) Lessor may accept any rent or performance of Lessee's 
obligations from any person other than Lessee pending approval or disapproval 
of an assignment. Neither a delay in the approval or disapproval of such 
assignment nor the acceptance of any rent for performance shall constitute a 
waiver or estoppel of Lessor's right to exercise its remedies for the Default 
or Breach by Lessee of any of the terms, covenants or conditions of this 
Lease.

           (c) The consent of 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 assignee 
or 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 under this Lease or the 
sublease and without obtaining their consent, and such action shall not 
relieve such persons from liability under this Lease or the sublease.

           (d) In the event of any Default or Breach of Lessee's obligation 
under this Lease, Lessor may proceed directly against Lessee, any Guarantors 
or anyone else responsible for the performance of the Lessee's obligations 
under this Lease, including any sublessee, without first exhausting Lessor's 
remedies against any other person or entity responsible therefor to Lessor, 
or any security held by Lessor.

           (e) Each request for consent to an assignment or subletting shall 
be in writing, accompanied by information relevant to Lessor's 
determination as to the financial and operational responsibility and 
appropriateness of the proposed assignee or sublessee, including but not 
limited to the intended use and/or required modification of the Premises, if 
any, together with a non-refundable deposit of $1,000 or ten percent (10%) of 
the monthly Base Rent applicable to the portion of the Premises which is the 
subject of the proposed assignment or sublease whichever is greater, as 
reasonable consideration for Lessor's considering and processing the request 
for consent Lessee agrees to provide Lessor with such other or additional 
information and/or documentation as may be reasonably requested by Lessor.

           (f) Any assignee of, or sublessee under, this Lease shall, by 
reason of accepting such assignment or entering into such sublease be deemed 
for the benefit of Lessor, to have assumed and agreed to conform and comply 
with each and every term, covenant, condition and obligation herein to be 
observed or performed by Lessee during the term of said assignment or 
sublease, other than such obligations as are contrary to or inconsistent with 
provisions of an assignment or sublease to which Lessor has specifically 
consented in writing.

           (g) The occurrence of a transaction described in Paragraph 12.2(c) 
shall give Lessor the right (but not the obligation) to require that the 
Security Deposit be increased by an amount equal to two (2) times the then 
monthly Base Rent, and Lessor may make the actual receipt by Lessor of the 
Security Deposit increase a condition to Lessor's consent to such transaction.

           (h) Lessor, as a condition to giving its consent to any assignment 
or subletting, may require that the amount and adjustment schedule of the 
rent payable under this Lease be adjusted to what is then the market value 
and/or adjustment schedule for property similar to the Premises as then 
constituted, as determined by Lessor.

     12.3  ADDITIONAL TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. 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) Lessee hereby assigns and transfers to Lessor all of Lessee's 
interest in all rentals and income arising from any sublease of all or a 
portion of the Premises heretofore or hereafter made by Lessee, and Lessor 
may collect such rent and income and apply same toward Lessee's obligations 
under this Lease, provided, however, that until a Breach (as defined in 
Paragraph 13.1) shall occur in the performance of Lessee's obligations under 
this Lease, Lessee may, except as otherwise provided in this Lease, receive, 
collect and enjoy the rents accruing under such sublease. Lessor shall not, 
by reason of the foregoing provision or any other assignment of such sublease 
to Lessor, nor by reason of the collection of the rents from a sublease, be 
deemed liable to the sublessee for any failure of Lessee to perform and 
comply with any of Lessee's obligations to such sublessee under such 
Sublease. Lessee hereby irrevocably authorizes and directs any such 
sublessee, upon receipt of a written notice from Lessor stating that a Breach 
exists in the performance of Lessee's obligations under this Lease, to pay to 
Lessor the rents and other charges due and to become due under the sublease. 
Sublessee shall rely upon any such statement and request from Lessor and 
shall pay such rents and other charges to Lessor without any obligation or 
right to inquire as to whether such Breach exists and notwithstanding any 
notice from or claim from Lessee to the contrary, Lessee shall have no right 
or claim against such sublessee, or, until the Breach has been cured, against 
Lessor, for any such rents and other charges so paid by said sublessee to 
Lessor.

           (b) In the event of a Breach by Lessee 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 the sublessor under 
such sublease from the time of the exercise of said option to the expiration 
of such sublease; provided, however, Lessor shall not be liable for any 
prepaid rents or security deposit paid by such sublessee to such sublessor or 
for any other prior defaults or breaches of such sublessor under such 
sublease.

           (c) Any matter or thing requiring the consent of the sublessor 
under a sublease shall also require the consent of Lessor herein.

           (d) No sublessee under a sublease approved by Lessor shall further 
assign or sublet all or any part of the Premises without Lessor's prior 
written consent.

           (e) Lessor shall deliver a copy of any notice of Default of Breach 
by Lessee to the sublessee, who shall have the right to cure the Default of 
Lessee within the grace period, if any, specified in such notice. The 
sublessee shall have a right of reimbursement and offset from and against 
Lessee for any such Defaults cured by the sublessee.

13.  DEFAULT; BREACH; REMEDIES.

     13.1  DEFAULT: BREACH. Lessor and Lessee agree that if an attorney is 
consulted by Lessor in connection with a Lessee Default or Breach (as 
hereinafter defined), $350.00 is a reasonable minimum sum per such occurrence 
for legal services and costs in the preparation and service of a notice of 
Default, and that Lessor may include the cost of such services and costs in 
said notice as rent due and payable to cure said default. A "Default" by 
Lessee is defined as a failure by Lessee to observe, comply with or perform 
any of the terms, covenants, conditions or rules applicable to Lessee under 
this Lease. A "Breach" by Lessee is defined as the occurrence of any one or 
more of the following Defaults, and, where a grace period for cure after 
notice is specified herein, the failure by Lessee to cure such Default prior 
to the expiration of the applicable grace period, and shall entitle Lessor to 
pursue the remedies set forth in Paragraphs 13.2 and/or 13.3:

           (a) The vacating of the Premises without the intention to reoccupy 
same, or the abandonment of the Premises.

           (b) Except as expressly otherwise provided in this Lease, the 
failure by Lessee to make any payment of Base Rent, Lessee's Share of Common 
Area Operating Expenses, or any other monetary payment required to be made by 
Lessee hereunder as and when due, the failure by Lessee to provide Lessor 
with reasonable evidence of insurance or surety bond required under this 
Lease, or the failure of Lessee to fulfill any obligation under this Lease 
which endangers or threatens life or property, where such failure continues 
for a period of three (3) days following written notice thereof by or on 
behalf of Lessor to Lessee.

           (c) Except as expressly otherwise provided in this Lease, the 
failure by Lessee to provide Lessor with reasonable written evidence (in duly 
executed original form, if applicable) of (i) compliance with Applicable 
Requirements per Paragraph 6.3, (ii) the inspection, maintenance and service 
contracts required under Paragraph 7.1(b), (iii) the rescission of an 
unauthorized assignment or subletting per Paragraph 12.1, (iv) a Tenancy 
Statement per Paragraphs 16 or 37, (v) the subordination or non-subordination 
of this Lease per Paragraph 30, (vi) the guaranty of the performance of 
Lessee's obligations under this Lease if required under Paragraphs 1.11 and 
37, (vii) the execution of any document requested under Paragraph 42 
(easements), or (viii) any other documentation or information which Lessor 
may reasonably require of Lessee under the terms of this lease, where any 
such failure continues for a period of ten (10) days following written notice 
by or on behalf of Lessor to Lessee.

           (d) A Default by Lessee as to the terms, covenants, conditions, or 
provisions of this Lease, or of the rules adopted under Paragraph 40 hereof 
that are to be observed, complied with or performed by Lessee, other than 
those described in Subparagraphs 13.1(a), (b) or (c), above, where such 
Default continues for a period of thirty (30) days after written notice 
thereof by or on behalf of Lessor to Lessee; provided, however, that if the 
nature of Lessee's Default is such that more than thirty (30) days are 
reasonably required for its cure, then it shall not be deemed to be a Breach 
of this Lease by Lessee if Lessee commences such cure within said thirty (30) 
day period and thereafter diligently prosecutes such cure to completion.

           (e) The occurrence of any of the following events: (i) the making 
by Lessee of any general arrangement or assignment for the benefit of 
creditors; (ii) Lessee's becoming a "debtor" as defined in 11 U.S. Code 
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 Lesse'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; provided, however, in the event that any provision of this 
Subparagraph 13.1(e) is contrary to any applicable law, such provision shall 
be of no force or effect, and shall not affect the validity of the remaining 
provisions.

           (f) The discovery by Lessor that any financial statement of Lessee 
or of any Guarantor, given to Lessor by Lessee or any Guarantor, was 
materially false.

           (g) If the performance of Lessee's obligations under this Lease is 
guaranteed: (i) the death of a Guarantor, (ii) the termination of a 
Guarantor's liability with respect to this Lease other than in accordance 
with the terms of such guaranty, (iii) a Guarantor's becoming insolvent or 
the subject of a bankruptcy filing, (iv) a Guarantor's refusal to honor the 
guaranty, or (v) a Guarantor's breach of its guaranty obligation on an 
anticipatory breach basis, and Lessee's failure, within sixty (60) days 
following written notice by or on behalf of Lessor to Lessee of any such 
event, to provide Lessor with written alternative assurances of security, 
which, when coupled with the then existing resources of Lessee, equals or 
exceeds the combined financial resources of Lessee and the Guarantors that 
existed at the time of execution of this Lease.

     13.2  REMEDIES. If Lessee fails to perform any affirmative duty or 
obligation of Lessee under this Lease, within ten (10) days after written 
notice to Lessee (or in case of an emergency, without notice), Lessor may at 
its option (but without obligation to do so), perform such duty or obligation 
on Lessee's behalf, including but not limited to the obtaining of reasonably 
required bonds, insurance policies, or governmental licenses, permits or 
approvals. The costs and expenses of any such performance by Lessor shall be 
due and payable by Lessee to Lessor upon invoice therefor. If any check given 
to Lessor by Lessee shall not be honored by the bank upon which it is drawn, 
Lessor, at its own option, may require all future payments to be made under 
this Lease by Lessee to be made only by cashier's check. In the event of a 
Breach of this Lease by Lessee (as defined in Paragraph 13.1), with or 
without further notice or demand, and without limiting Lessor in the exercise 
of any right or remedy which Lessor may have by reason of such Breach, Lessor 
may:

           (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: (i) the worth 
at the time of the award of the unpaid rent which had been earned at the time 
of termination; (ii) the worth at the time of award of the amount by which 
the unpaid rent which would have been earned after termination until the time 
of award exceeds the amount of such rental loss that the Lessee proves could 
have been reasonably avoided; (iii) the worth at the time of award of the 
amount by which the unpaid rent for the balance of the term after the time of 
award exceeds the amount of such rental loss that the Lessee proves could be 
reasonably avoided; and (iv) any other amount necessary to compensate Lessor 
for all the detriment proximately caused by the Lessee's failure to perform 
its obligations under this Lease or which in the ordinary course of things 
would be likely to result therefrom, 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 that portion of any leasing commission paid by Lessor in connection 
with this Lease applicable to the unexpired term of this Lease. The worth at 
the time of award of the amount referred to in provision (iii) of the 
immediately preceding sentence shall be computed by discounting such amount 
at the discount rate of the Federal Reserve Bank of San Francisco or the 
Federal Reserve Bank District in which the Premises are located at the time 
of award plus one percent (1%). Efforts by Lessor to mitigate damages caused 
by Lessee's Default or Breach of this Lease shall not waive Lessor's right to 
recover damages under this Paragraph 13.2 if termination of this Lease is 
obtained through the provisional remedy of unlawful detainer. Lessor shall 
have the right to recover in such proceeding the unpaid rent and damages as 
are recoverable therein, or Lessor may reserve the right to recover all or 
any part thereof in a separate suit for such rent and/or damages. If a notice 
and grace period required under Subparagraph 13.1(b), (c) or (d) was not 
previously given, a notice to pay rent or quit, or to perform or quit, as the 
case may be, given to Lessee under any statute authorizing the forfeiture of 
leases for unlawful detainer shall also constitute the applicable notice for 
grace period purposes required by Subparagraph 13.1(b), (c) or (d). In such 
case, the applicable grace period under the unlawful detainer statute shall 
run concurrently after the one such statutory notice, and the failure of 
Lessee to cure the Default within the greater of the two (2) such grace 
periods shall constitute both an unlawful detainer and a Breach of this Lease 
entitling Lessor to the remedies provided for in this Lease and/or by said 
statute.

           (b) Continue the Lease and Lessee's right to possession in effect 
(in California under California Civil Code Section 1951.4) after Lessee's 
Breach and recover the rent as it become due, provided Lessee has the right 
to sublet or assign, subject only to reasonable limitations. Lessor and 
Lessee agree that the limitations on assignment and subletting in this Lease 
are reasonable. Acts of maintenance or preservation, efforts to relet the 
Premises, or the appointment of a receiver to protect the Lessor's interest 
under this Lease, shall not constitute a termination of the Lessee's right to 
possession.

           (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.

                                                                    ----------

<PAGE>

          (d)  The expiration or termination of this Lease and/or the
termination of Lessee's right to possession shall not relieve Lessee from
liability under any indemnity provisions of this Lease as to matters occurring
or accruing during the term hereof or by reason of Lessee's occupancy of the
Premises.

     13.3 INDUCEMENT RECAPTURE IN EVENT OF BREACH. Any agreement by Lessor for
free or abated rent or other charges applicable to the Premises, or for the
giving or paying by Lessor to or for Lessee of any cash or other bonus, 
inducement or consideration for Lessee's entering into this Lease, all of which
concessions are hereinafter referred to as "Inducement Provisions" shall be
deemed conditioned upon Lessee's full and faithful performance of all of the
terms, covenants and conditions of this Lease to be performed or observed by
Lessee during the term hereof as the same may be extended. Upon the occurrence
of a Breach (as defined in Paragraph 13.1) of this Lease by Lessee, any such
Inducement Provision shall automatically be deemed deleted from this Lease and
of no further force or effect, and any rent, other charge, bonus, inducement or
consideration theretofore abated, given or paid by Lessor under such an
Inducement Provision shall be immediately due and payable by Lessee to Lessor,
and recoverable by Lessor, as additional rent due under this Lease,
notwithstanding any subsequent cure of said Breach by Lessee. The acceptance by
Lessor of rent or the cure of the Breach which initiated the operation of this
Paragraph 13.3 shall not be deemed a waiver by Lessor of the provisions of this
Paragraph 13.3 unless specifically so stated in writing by Lessor at the time of
such acceptance.

     13.4 LATE CHARGES*. Lessee hereby acknowledges that late payment by Lessee
to Lessor of rent and 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 upon Lessor by the
terms of any ground lease, mortgage or deed of trust covering the Premises.
Accordingly, if any installment of rent or 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 six percent (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 or Breach with respect to such overdue amount, nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder. In the event that a late charge is payable hereunder, whether or not
collected, for three (3) consecutive installments of Base Rent, then
notwithstanding Paragraph 4.1 or any other provision of this Lease to the
contrary, Base Rent shall, at Lessor's option, become due and payable quarterly
in advance. *REFER TO PARAGRAPH 52 BELOW.

     13.5 BREACH BY LESSOR. Lessor shall not be deemed in breach of this 
Lease unless Lessor falls within a reasonable time to perform an obligation 
required to be performed by Lessor. For purposes of this Paragraph 13.5, a 
reasonable time shall in no event be less than thirty (30) days after receipt 
by Lessor, and by any Lender(s) whose name and address shall have been 
furnished to Lessee in writing for such purpose, of written notice specifying 
wherein such obligation of Lessor has not been performed; provided, however, 
that if the nature of Lessor's obligation is such that more than thirty (30) 
days after such notice are reasonably required for its performance, then 
Lessor shall not be in breach of this Lease if performance is commenced 
within such thirty (30) day period and thereafter diligently pursued to 
completion.

14.  CONDEMNATION. If the Premises or any portion thereof are taken under the 
power of eminent domain or sold under the threat of the exercise of said 
power (all of which are herein called "condemnation"), this Lease shall 
terminate as to the part so taken as of the date the condemning authority takes 
title or possession, whichever first occurs. If more than ten percent (10%) 
of the floor area of the Premises, or more than twenty-five percent (25%) of 
the portion of the Common Areas designated for Lessee's parking, is taken by 
condemnation, Lessee may, at Lessee's option, to be exercised in writing 
within ten (10) days after Lessor shall have given Lessee written notice of 
such taking (or in the absence of such notice, within ten (10) days after the 
condemning authority shall have taken possession) terminate this Lease as of 
the date the condemning authority takes such possession. If Lessee does not 
terminate this Lease in accordance with the foregoing, this Lease shall 
remain in full force and effect as to the portion of the Premises remaining, 
except that the Base Rent shall be reduced in the same proportion as the 
rentable floor area of the Premises taken bears to the total rentable floor 
area of the Premises. No reduction of Base Rent shall occur if the 
condemnation does not apply to any portion of the Premises. Any award for the 
taking of all or any part of the Premises under the power of eminent domain 
or any payment made under threat of the exercise of such power shall be the 
property of Lessor, whether such award shall be made as compensation for 
diminution of value of the leasehold or for the taking of the fee, or as 
severance damages; provided, however, that Lessee shall be entitled to any 
compensation, separately awarded to Lessee for Lessee's relocation expenses 
and/or loss of Lessee's Trade Fixtures. In the event that this Lease is not 
terminated by reason of such condemnation, Lessor shall to the extent of its 
net severance damages received, over and above Lessee's Share of the legal 
and other expenses incurred by Lessor in the condemnation matter, repair any 
damage to the Premises caused by such condemnation authority. Lessee shall be 
responsible for the payment of any amount in excess of such net severance 
damages required to complete such repair.

15.  BROKERS' FEES.

     15.1 PROCURING CAUSE.* The Broker(s) named in Paragraph 1.10 is/are the
procuring cause of this Lease. *REFER TO PARAGRAPH 55 BELOW.

     DELETE PARAGRAPH 15.2

     DELETE PARAGRAPH 15.3

     15.4 REPRESENTATIONS AND WARRANTIES. Lessee and Lessor each represent and
warrant to the other that it has had no dealings with any person, firm, broker
or finder other than as named in Paragraph 1.10(a) in connection with the
negotiation of this Lease and/or the consummation of the transaction
contemplated hereby, and that no broker or other person, firm or entity other
than said named Broker(s) is entitled to any commission or finder's fees in
connection with said transaction. Lessee and Lessor do each hereby agree to
indemnify, protect, defend and hold the other harmless from and against
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, including any costs, expenses, and/or attorneys' fees
reasonably incurred with respect thereto.

16.  TENANCY AND FINANCIAL STATEMENTS.

     16.1 TENANCY STATEMENT. Each Party (as "Responding Party") shall within ten
(10) days after written notice from the other Party (the "Requesting Party")
execute, acknowledge and deliver to the Requesting Party a statement in writing
in a form similar to the then most current "Tenancy Statement" form published by
the American Industrial Real Estate Association, plus such additional
information, confirmation and/or statements as may be reasonably requested by
the Requesting Party.

     16.2 FINANCIAL STATEMENT. If Lessor desires to finance, refinance, or sell
the Premises or the Building, or any part thereof, Lessee and all Guarantors
shall deliver to any potential lender or purchaser designated by Lessor such
financial statements of Lessee and such Guarantors as may be reasonably required
by such lender or purchaser, including but not limited to Lessee's financial
statements for the past three (3) years. 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 the owner
or owners at the time in question of the fee title to the Premises. In the event
of a transfer of Lessor's title or interest in the Premises or in this Lease,
Lessor shall deliver to the transferee or assignee (in cash or by credit) any
unused Security Deposit held by Lessor at the time of such transfer or
assignment. Except as provided in Paragraph 15.3, upon such transfer or
assignment and delivery of the Security Deposit, as aforesaid, the prior Lessor
shall be relieved of all liability with respect to the obligations and/or
covenants under this Lease thereafter to be performed by the Lessor. Subject to
the foregoing, the obligations and/or covenants in this Lease to be performed by
the Lessor shall be binding only upon the Lessor as hereinabove defined.

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. Any monetary payment due Lessor 
hereunder, other than late charges, not received by Lessor within ten (10) 
days following the date on which it was due, shall bear interest from the 
date due at the prime rate charged by the largest state chartered bank in the 
state in which the Premises are located plus four percent (4%) per annum, but 
not exceeding the maximum rate allowed by law, in addition to the potential 
late charge provided for in Paragraph 13.4.

20.  TIME OF ESSENCE. Time is of the essence with respect to the performance of
all obligations to be performed or observed by the Parties under this Lease.

21.  RENT DEFINED. All monetary obligations of Lessee to Lessor under the terms
of this Lease are deemed to be rent.

22.  NO PRIOR OR OTHER AGREEMENTS; BROKER DISCLAIMER. This Lease contains all 
agreements between the Parties with respect to any matter mentioned herein, 
and no other prior or contemporaneous agreement or understanding shall be 
effective. Lessor and Lessee each represents and warrants to the Brokers that 
it has made, and is relying solely upon, its own investigation as to the 
nature, quality, character and financial responsibility of the other Party to 
this Lease and as to the nature, quality and character of the Premises. 
Brokers have no responsibility with respect thereto or with respect to any 
default or breach hereof by either Party. Each Broker shall be an intended 
third party beneficiary of the provisions of this Paragraph 22.

23.  NOTICES.

     23.1 NOTICE REQUIREMENTS. All notices required or permitted by this 
Lease shall be in writing and may be delivered in person (by hand or by 
messenger or courier service) or may be sent by regular, certified or 
registered mail or U.S. Postal Service Express Mail, with postage prepaid, or 
by facsimile transmission during normal business hours, and shall be deemed 
sufficiently given if served in a manner specified in this Paragraph 23. The 
addresses noted adjacent to a Party's signature on this Lease shall be that 
Party's address for delivery or mailing of notice purposes. Either Party may 
be written 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 the purpose of mailing or 
delivering notices to Lessee. 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 written notice to Lessee.

     23.2 DATE OF NOTICE. Any notice sent by registered or certified mail,
return receipt requested, shall be deemed given on the date of delivery shown on
the receipt card, or if no delivery date is shown, the postmark thereon. If sent
by regular mail, the notice shall be deemed given forty-eight (48) hours after
the same is addressed as required herein and mailed with postage prepaid.
Notices delivered by United States Express Mail or overnight courier that
guarantees next day

                                                                          ------

delivery shall be deemed given twenty-four (24) hours after delivery of the same
to the United States Postal Service or courier. If any notice is transmitted by
facsimile transmission or similar means, the same shall be deemed served or
delivered upon telephone or facsimile confirmation of receipt of the
transmission thereof, provided a copy is also delivered via delivery of mail. If
notice is received on a Saturday or a Sunday or a legal holiday, it shall be
deemed received on the next business day.

24.  WAIVERS. No waiver by Lessor of the Default or Breach of any term, 
covenant or condition hereof by Lessee, shall be deemed a waiver of any other 
term, covenant or condition hereof, or of any subsequent Default or Breach by 
Lessee of the same or any other term, covenant or condition hereof. Lessor's 
consent to, or approval of, any such act shall not be deemed to render 
unnecessary the obtaining of Lessor's consent to, or approval of, any 
subsequent or similar act by Lessee, or be construed as the basis of an 
estoppel to enforce the provision or provisions of this Lease requiring such 
consent. Regardless of Lessor's knowledge of a Default or Breach at the time 
of accepting rent, the acceptance of rent by Lessor shall not be a waiver of 
any Default or Breach by Lessee of any provision hereof. Any payment given 
Lessor by Lessee may be accepted by Lessor on account of moneys or damages 
due Lessor, notwithstanding any qualifying statements or conditions made by 
Lessee in connection therewith, with such statements and/or conditions shall 
be of no force or effect whatsoever unless specifically agreed to in writing 
by Lessor at or before the time of deposit of such payment.

25.  RECORDING. Either Lessor or Lessee shall, upon request of the other, 
execute, acknowledge and deliver to the other a short term memorandum of this 
Lease for recording purposes. The Party requesting recordation shall be 
responsible for payment of any fees or taxes applicable thereto.

26.  NO RIGHT TO HOLDOVER. Lessee has no right to retain possession of the 
Premises or any part thereof beyond the expiration or earlier termination of 
this Lease. In the event that Lessee holds over in violation of this 
Paragraph 26 then the Base Rent payable from and after the time of the 
expiration or earlier termination of this Lease shall be increased to one 
hundred twenty-five percent (125%) of the Base Rent applicable during the 
month immediately preceding such expiration or earlier termination. Nothing 
contained herein shall be construed as a consent by Lessor to any holding 
over by Lessee.

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. All provisions of this Lease to be observed or
performed by Lessee are both covenants and conditions.

29.  BINDING EFFECT; CHOICE OF LAW. This Lease shall be binding upon the
Parties, their personal representatives, successors and assigns and be governed
by the laws of the State in which the Premises are located. Any litigation
between the Parties hereto concerning this Lease shall be initiated in the
county in which the Premises are located.

30.  SUBORDINATION; ATTORNMENT; NON-DISTURBANCE.

     30.1 SUBORDINATION. This Lease and any Option granted hereby shall be
subject and subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "Security Device"), now or
hereafter placed by Lessor upon the real property of which the Premises are a
part, to any and all advances made on the security thereof, and to all renewals,
modifications, consolidations, replacements and extensions thereof. Lessee
agrees that the Lenders holding any such Security Device shall have no duty,
liability or obligation to perform any of the obligations of Lessor under this
Lease, but that in the event of Lessor's default with respect to any such
obligation, Lessee will give any Lender whose name and address have been
furnished Lessee in writing for such purpose notice of Lessor's default pursuant
to Paragraph 13.5. If any Lender shall elect to have this Lease and/or any
Option granted hereby superior to the lien of its Security Device and shall give
written notice thereof to Lessee, this Lease and such Options shall be deemed
prior to such Security Device, notwithstanding the relative dates of the
documentation or recordation thereof.

     30.2 ATTORNMENT. Subject to the non-disturbance provisions of Paragraph
30.3, Lessee agrees to attorn to a Lender or any other party who acquires
ownership of the Premises by reason of a foreclosure of a Security Device, and
that in the event of such foreclosure, such new owner shall not: (i) be liable
for any act or omission of any prior lessor or with respect to events occurring
prior to acquisition of ownership, (ii) be subject to any offsets or defenses
which Lessee might have against any prior lessor, or (iii) be bound by
prepayment of more than one month's rent.

     30.3 NON-DISTURBANCE. With respect to Security Devices entered into by
Lessor after the execution of this Lease, Lessee's subordination of this Lease
shall be subject to receiving assurance (a "non-disturbance agreement") from the
Lender that Lessee's possession and this Lease, including any options to extend
the term hereof, will not be disturbed so long as Lessee is not in Breach hereof
and attorns to the record owner of the Premises.

     30.4 SELF-EXECUTING. The agreements contained in this Paragraph 30 shall be
effective without the execution of any further documents; provided, however,
that upon written request from Lessor or a Lender in connection with a sale,
financing or refinancing of Premises, Lessee and Lessor shall execute such
further writings as may be reasonably required to separately document any such
subordination or non-subordination, attornment and/or non-disturbance agreement
as is provided for herein.

31.  ATTORNEYS' FEES. If any Party or Broker brings an action or proceeding to
enforce the terms hereof or declare rights hereunder, the Prevailing Party (as
hereafter defined) in any such proceeding, action, or appeal thereon, shall be
entitled to reasonable attorneys' fees. Such fees may be awarded in the same
suit or recovered in a separate suit, whether or not such action or proceeding
is pursued to decision or judgment. The term "Prevailing Party" shall include,
without limitation, a Party or Broker who substantially obtains or defeats the
relief sought, as the case may be, whether by compromise, settlement, judgment,
or the abandonment by the other Party or Broker of its claim or defense. 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. Lessor shall be entitled to attorneys' fees, costs and expenses
incurred in preparation and service of notices of Default and consultations in
connection therewith, whether or not a legal action is subsequently commenced in
connection with such Default or resulting Breach. Broker(s) shall be intended
third party beneficiaries of this Paragraph 31.

32.  LESSOR'S ACCESS: SHOWING PREMISES; REPAIRS. Lessor and Lessor's agents 
shall have the right to enter the Premises at any time, in the case of an 
emergency, and otherwise at reasonable times for the purpose of showing the 
same to prospective purchasers, lenders, or lessees, and making such 
alterations, repairs, improvements or additions to the Premises or to the 
Building, as Lessor may reasonably deem necessary. Lessor may at any time 
place on or about the Premises or Building any ordinary "For Sale" signs and 
Lessor may at any time during the last two hundred seventy (270) days of the 
term hereof place on or about the Premises any ordinary "For Lease" signs. 
All such activities of Lessor shall be without abatement of rent or liability 
to Lessee.

33.  AUCTIONS. Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises 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.

34.  SIGNS. Lessee shall not place any sign upon the exterior of the Premises 
or the Building, except that Lessee may, with Lessor's prior written consent, 
install (but not on the roof) such signs as are reasonably required to 
advertise Lessee's own business so long as such signs are in a location 
designated by Lessor and comply with Applicable Requirements and the signage 
criteria established for the Industrial Center by Lessor. The installation of 
any sign on the Premises by or for Lessee shall be subject to the provisions 
of Paragraph 7 (Maintenance, Repairs, Utility Installations, Trade Fixtures 
and Alterations). Unless otherwise expressly agreed herein, Lessor reserves 
all rights to the use of the roof of the Building, and the right to install 
advertising signs on the Building, including the roof, which do not 
unreasonably interfere with the conduct of Lessee's business; Lessor shall be 
entitled to all revenues from such advertising signs.

35.  TERMINATION; MERGER. Unless specifically stated otherwise in writing by 
Lessor, the voluntary or other surrender of this Lease by Lessee, the mutual 
termination or cancellation hereof, or a termination hereof by Lessor for 
Breach by Lessee, shall automatically terminate any sublease or lesser estate 
in the Premises; provided, however, Lessor shall, in the event of any such 
surrender, termination or cancellation, have the option to continue any one 
or all of any existing subtenancies. Lessor's failure within ten (10) days 
following any such event to make a written election to the contrary by 
written notice to the holder of any such lesser interest, shall constitute 
Lessor's election to have such event constitute the termination of such 
interest.

36.  CONSENTS.

          (a)  Except for Paragraph 33 hereof (Auctions) or as otherwise 
provided herein, wherever in this Lease the consent of a Party is required to 
an act by or for the other Party, such consent shall not be unreasonably 
withheld or delayed. Lessor's actual reasonable costs and expenses (including 
but not limited to architects', attorneys', engineers' and other consultants' 
fees) incurred in the consideration of, or response to, a request by Lessee 
for any Lessor consent pertaining to this Lease or the Premises, including 
but not limited to consents to an assignment a subletting or the presence or 
use of a Hazardous Substance, shall be paid by Lessee to Lessor upon receipt 
of an invoice and supporting documentation therefor. In addition to the 
deposit described in Paragraph 12.2(e), Lessor may, as a condition to 
considering any such request by Lessee, require that Lessee deposit with 
Lessor an amount of money (in addition to the Security Deposit held under 
Paragraph 5) reasonably calculated by Lessor to represent the cost Lessor 
will incur in considering and responding to Lessee's request. Any unused 
portion of said deposit shall be refunded to Lessee without interest. 
Lessor's consent to any act, assignment of this Lease or subletting of the 
Premises by Lessee shall not constitute an acknowledgment that no Default or 
Breach by Lessee of this Lease exists, nor shall such consent be deemed a 
waiver of any then existing Default or Breach, except as may be otherwise 
specifically stated in writing by Lessor at the time of such consent.

          (b)  All conditions to Lessor's consent authorized by this Lease are
acknowledged by Lessee as being reasonable. The failure to specify herein any
particular condition to Lessor's consent shall not preclude the impositions by
Lessor at the time of consent of such further or other conditions as are then
reasonable with reference to the particular matter for which consent is being
given.

37.  GUARANTOR.

     37.1 FORM OF GUARANTY. If there are to be any Guarantors of this Lease 
per Paragraph 1.11, the form of the guaranty to be executed by each such 
Guarantor shall be in the form most recently published by the American 
Industrial Real Estate Association, and each such Guarantor shall have the 
same obligations as Lessee under this lease, including but not limited to the 
obligation to provide the Tenancy Statement and information required in 
Paragraph 16.

     37.2 ADDITIONAL OBLIGATIONS OF GUARANTOR. It shall constitute a Default of
the Lessee under this Lease if any such Guarantor fails or refuses, upon
reasonable request by Lessor to give: (a) evidence of the due execution of the
guaranty called for by this Lease, including the authority of the Guarantor (and
of the party signing on Guarantor's behalf) to obligate such Guarantor on said
guaranty, and resolution of its board of directors authorizing the making of
such guaranty, together with a certificate of incumbency showing the signatures
of the persons authorized to sign on its behalf, (b) current financial
statements of Guarantor as may from time to time be requested by Lessor, (c) a
Tenancy Statement, or (d) written confirmation that the guaranty is still in
effect.

38.  QUIET POSSESSION. Upon payment by Lessee of the rent for the Premises and
the performance of all of the covenants, conditions and provisions on Lessee's
part to be observed and performed under this Lease, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease.


                                                                Initials:       
                                                                          ------

                                                                          ------

39.  OPTIONS.

     39.1  DEFINITION.  As used in this Lease, the word "Option" has the 
following meaning: (a) the right 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; (b) the 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 property of Lessor or the right of first offer to lease other property 
of Lessor; (c) the right to purchase the Premises, or the right of first 
refusal to purchase the Premises, or the right of first offer to purchase the 
Premises, or the right 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.

     39.2  OPTIONS PERSONAL TO ORIGINAL LESSEE.  Each Option granted to 
Lessee in this Lease is personal to the original Lessee named in Paragraph 
1.1 hereof, and cannot be voluntarily or involuntarily assigned or exercised 
by any person or entity other than said original Lessee while the original 
Lessee is in full and actual possession of the Premises and without the 
intention of thereafter assigning or subletting. The Options, if any, herein 
granted to Lessee are not assignable, either as a part of an assignment of 
this Lease or separately or apart therefrom, and no Option may be separated 
from this Lease in any manner, by reservation or otherwise.

     39.3  MULTIPLE OPTIONS.  In the event that Lessee has any multiple 
Options to extend or renew this Lease, a letter option cannot be exercised 
unless the prior Options to extend or renew this Lease have been validly 
exercised.

     39.4  EFFECT OF DEFAULT ON OPTIONS.

     (a)  Lessees shall have no right to exercise an Option, notwithstanding 
any provision in the grant of Option to the contrary: (1) during the period 
commencing with the giving of any notice of Default under Paragraph 13.1 and 
continuing until the noticed Default is cured, or (ii) during the period of 
time any monetary obligation due Lessor from Lessee is unpaid (without regard 
to whether notice thereof is given Lessee), or (iii) during the time Lessee 
is in Breach of this Lease, or (iv) in the event that Lessor has given to 
Lessee three (3) or more notices of separate Defaults under Paragraph 13.1 
during the twelve (12) month period immediately preceding the exercise of the 
Option, whether or not the Defaults are cured.

     (b)  The period of time within which an Option may be exercised shall 
not be extended or enlarged by reason of Lessee's inability to exercise an 
Option because of the provisions of Paragraph 39.4(a).

     (c)  All rights of Lessee under the provisions of an Option shall 
terminate and be of no further force or effect, notwithstanding Lessee's due 
and timely exercise of the Option. If, after such exercise and during the 
term of this Lease, (i) Lessee fails to pay to Lessor a monetary obligation 
of Lessee for a period of thirty (30) days after such obligation becomes due 
(without any necessity of Lessor to give notice thereof to Lessee); or (ii) 
Lessor gives to Lessee three (3) or more notices of separate Defaults under 
Paragraph 13.1 during any twelve (12) month period, whether or not the 
Defaults are cured, or (iii) if Lessee commits a Breach of this Lease.

40.  RULES AND REGULATIONS.  Lessee agrees that it will abide by, and keep 
and observe all reasonable rules and regulations ("Rules and Regulations") 
which Lessor may make from time to time for the management, safety, care, and 
cleanliness of the grounds, the parking and unloading of vehicles and the 
preservation of good order, as well as for the convenience of other occupants 
or tenants of the Building and the Industrial Center and their invitees.

41.  SECURITY MEASURES.  Lessee hereby acknowledges that the rental payable 
to Lessor hereunder does not include the cost of guard service or other 
security measures, and that Lessor shall have no obligation whatsoever to 
provide same. Lessee assumes all responsibility for the protection of the 
Premises, Lessee, its agents and invitees and their property from the acts of 
third parties.

42.  RESERVATIONS.  Lessor reserves the right, from time to time, to grant, 
without the consent or joinder of Lessee, such easements, rights of way, 
utility raceways, and dedications that Lessor deems necessary, and to cause 
the recordation of parcel maps and restrictions, so long as such easements, 
rights of way, utility raceways, dedications, maps and restrictions do not 
reasonably interfere with the use of the Premises by Lessee. Lessee agrees 
to sign any documents reasonably requested by Lessor to effectuate any such 
easement rights, dedication, map or restrictions.

43.  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.

44.  AUTHORITY.  If either Party hereto is a corporation, trust, or general or 
limited partnership, each individual executing this Lease on behalf of such 
entity represents and warrants that he or she is duly authorized to execute 
and deliver this Lease on its behalf. If Lessee is a corporation, trust or 
partnership, Lessee shall, within thirty (30) days after request by Lessor, 
deliver to Lessor evidence satisfactory to Lessor of such authority.

45.  CONFLICT.  Any conflict between the printed provisions of this Lease and 
the typewritten or handwritten provisions shall be controlled by the 
typewritten or handwritten provisions.

46.  OFFER.  Preparation of this Lease by either Lessor or Lessee or Lessor's 
agent or Lessee's agent and submission of same to Lessee or Lessor shall not 
be deemed an offer to lease. This Lease is not intended to be binding until 
executed and delivered by all Parties hereto.

47.  AMENDMENTS.  This Lease may be modified only in writing, signed by the 
parties in interest at the time of the modification. The Parties shall amend 
this Lease from time to time to reflect any adjustments that are made to the 
Base Rent or other rent payable under this Lease. As long as they do not 
materially change Lessee's obligations hereunder, Lessee agrees to make such 
reasonable non-monetary modifications to this Lease as may be reasonably 
required by an institutional insurance company or pension plan Lender in 
connection with the obtaining of normal financing or refinancing of the 
property of which the Premises are a part.

48.  MULTIPLE PARTIES.  Except as otherwise expressly provided herein, if 
more than one person or entity is named herein as either Lessor or Lessee, 
the obligations of such multiple persons shall be the joint and several 
responsibility of all persons or entities named herein as such Lessor or 
Lessee.

 ADDENDUM TO STANDARD INDUSTRIAL/COMMERCIAL MULTI TENANT LEASE - MODIFIED NET
              PARTIES: WILLOW ROAD ASSOCIATES, LLC (LESSOR), 
                 LIVINGSTON ENTERPRISES, INC. (LESSEE).
                             DATED: JANUARY 24, 1996


49. EARLY POSSESSION.  Lessee shall be granted possession of a portion of the 
Premises, as determined by Lessor in its sole and absolute discretion, on 
October 1, 1996, provided: (i) Lessee does not interfere with the 
construction of the improvements contemplated by this Lease or any seismic 
work that Lessor may elect to perform, nor cause a delay in such 
construction, and (ii) all governing authorities having jurisdiction over the 
Premises approve of Lessee's partial occupancy during the course of 
construction. In the event that Lessee's acts, changes, or omissions during 
such early possession causes a delay in completion of the improvements or 
seismic work, as determined by Lessor in its sole and absolute discretion, 
such delay shall not alter or affect the scheduled Commencement Date and 
Lessee shall pay Base Rent as of the Commencement Date even if the 
improvements and seismic work are not completed. In the event Lessee's early 
possession causes an increase in the cost to construct the improvements or 
seismic work, as determined by Lessor in its sole and absolute discretion, 
then Lessee shall pay Lessor on demand for such increase, regardless of the 
total cost of said improvements or seismic work. Notwithstanding anything to 
the contrary contained in this Lease, if partial possession is not tendered 
to Lessee on the scheduled Early Possession Date, the period free of the 
obligation to pay Base Rent shall terminate on the date prior to the 
Commencement Date and shall not extend for any period thereafter.

50. RENT INCREASE.  Commencing May 1, 1999 and continuing through October, 
2001, the monthly Base Rent shall be $52,000.00. Commencing November 1, 2001 
and continuing through the remainder of the Original Term, the monthly Base 
Rent shall be $55,500.00.

51. PARKING.  Notwithstanding anything to the contrary contained in paragraph 
2.6 above, Lessee shall not park nor permit to be parked any inoperative 
vehicles on any portion of the Common Areas.

52. LATE CHARGES.  In reference to paragraph 13.4 above, the ten (10) day time 
period for performance shall end at 4:00 PM Pacific Time on the tenth (10th) 
calendar day. If the ten (10) day time period for performance ends on a 
Saturday, Sunday, or federal, state, city or legal holiday, then such date 
for performance shall be extended to 4:00 PM Pacific Time on the following

holiday. Notwithstanding anything to the contrary contained in paragraph 13.4 
above or this paragraph 52, Lessor agrees to waive the late charge the first 
time only, AND FOR NO OTHER TIME, Lessee fails to pay rent or any other sum

being notified by Lessor that the rent or other sum due is late.

53. PETS.  Lessee shall not keep or permit to be kept any pets within the 
Premises, Common Areas, or Industrial Center at any time.

54. FINANCIAL STATEMENTS.  Lessee shall provide Lessor with additional 
financial statements and credit references as Lessor may require prior to the 
execution of this Lease.

55. CONFIDENTIALITY.  Lessee and Broker agree to keep every part of this Lease 
confidential and not to disclose nor advertise any of the terms and 
conditions of this Lease without the Lessor's prior written consent.

56. IMPROVEMENTS.  Immediately upon execution and delivery of this Lease, 
Lessor and Lessee agree to meet with Lessor's architect to plan alterations 
and improvements to the Premises. Lessor and Lessee agree to cooperate and 
work expeditiously in finalizing a floor plan within one month of the 
execution of this Lease. Commencing on the later of the Early Possession Date 
or the date which Lessor receives a building permit to construct the 
improvements, Lessor, at Lessor's expense, and subject to possible 
reimbursement below, shall begin the improvement work as indicated on the 
improvement plans. Lessor's cost for the improvements, including the cost of 
architectural and engineering, building permits, plan check, fees, fire 
protection, ADA compliance, and all other improvement-related costs requested 
by Lessee or required by any governing authority, excepting only the cost to 
repaint the Building, shall not exceed $200,000.00. In the event it is 
estimated that the cost shall exceed $200,000.00, then prior to the

contrary contained above, Lessor, at Lessor's expense, shall repaint the 
exterior of the Building on or before December 31, 1996.

57. OPTION TO EXTEND.  Subject to the provisions contained in paragraph 39 
above, Lessee shall have the right, at its option, to extend the term of this 
Lease for a period of five (5) years commencing November 1, 2004 (the 
"Extension Term"). If Lessee elects to extend this Lease pursuant to this 
paragraph 57, Lessee shall give unequivocal written notice ("Exercise 
Notice") of its exercise to Lessor not less than two hundred seventy (270) 
days prior to the Expiration Date of the Original Term. Lessee's failure to 
give the Exercise Notice in a timely manner shall be deemed a waiver of 
Lessee's right to extend. The terms, covenants and conditions applicable to 
the Extension Term shall be the same terms, covenants and conditions of this 
Lease except that (1) Lessee shall not be entitled to any further option to 
extend for any period after the Extension Term, and (2) the Base Rent for the 
Premises shall be increased as provided in this paragraph 57.

DETERMINATION OF BASE RENT DURING THE EXTENSION TERM:

     (i)  AGREEMENT ON RENT.  Lessor and Lessee shall have sixty (60) days 
after Lessor receives the Exercise Notice in which to agree on the Base Rent 
during the Extension Term, which shall be the fair market rental value of the 
Premises during the Extension Term. In determining the fair market rental 
value of the Premises during the Extension Term, consideration shall be given 
to the uses of the premises permitted under this Lease, the quality, size, 
design and location of the Premises, and the rental value of comparable space 
located the Pleasanton area with similar quality improvements to the 
improvements in existence on the date of the extension. In no event shall the 
Base Rent for the Extension Term be less than the Base Rent last payable 
under this Lease during the Original Term. If Lessor and Lessee agree on the 
Base Rent for the Extension Term during the sixty (60) day period, they shall 
immediately execute an amendment to this Lease stating the Base Rent.

<PAGE>

     (ii)  SELECTION OF APPRAISERS.  If Lessor and Lessee are unable to agree 
on the Base Rent for the Extension Term within the sixty (60) day period, 
then within ten (10) days after the expiration of the sixty (60) day period, 
Lessor and Lessee each, at its cost and by giving notice to the other party, 
shall appoint a competent disinterested real estate appraiser with at least 
five (5) years' full time commercial appraisal experience in the geographical 
area of the Building to appraise and set the Base Rent during the Extension 
Term. If either Lessor or Lessee 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 during the Extension Term. If two (2) appraisers are 
appointed by Lessor and Lessee as stated in this paragraph, they shall meet 
promptly and attempt to set the Base Rent during the Extension Term. If two 
(2) appraisers are unable to agree within thirty (30) days after the second 
appraiser has been appointed, they shall attempt to select a third appraiser 
meeting the qualifications stated in this paragraph within ten (10) days 
after the last day the two (2) appraisers are given to set the Base Rent. 
If they are unable to agree on the third appraiser, either Lessor or Lessee, by
giving ten (10) days' notice to the other party, can apply to the then 
president of the real estate board of the county in which the Building is 
located, or to the Presiding Judge of the Superior Court of the county in which
the Building is located, for the selection of a third appraiser who meets the 
qualifications stated in this paragraph. Lessor and Lessee each shall bear 
one-half (1/2) of the cost of appointing the third appraiser and of paying 
the third appraiser's fee. The third appraiser, however selected, shall be a 
person who has not previously acted in any capacity for either Lessor or 
Lessee.

     (iii)  VALUE DETERMINED BY THREE (3) APPRAISERS.  Within thirty (30) days 
after the selection of the third appraiser, a majority of the appraisers 
shall set the Base Rent for the Extension Term. If a majority of the 
appraisers is unable to set the Base Rent within the stipulated period of 
time, Lessor's appraiser shall arrange for simultaneous exchange of written 
appraisals from each of the appraisers and the three (3) appraisals shall be 
added together and their total divided by three (3); the resulting quotient 
shall be the Base Rent for the Premises during the Extension Term. If, 
however, the low appraisal and/or high appraisal are/is more than ten percent 
(10%) lower and/or higher than the middle appraisal, the low appraisal and/or 
the high appraisal shall be disregarded. If only one (1) appraisal is 
disregarded, the remain two (2) appraisals shall be added together and their 
total divided by two (2); the resulting quotient shall be the Base Rent for 
the Premises during the Extension Term. If both the low appraisal and the 
high appraisal are disregarded as stated this paragraph, the middle appraisal 
shall be the Base Rent for the Premises during the Extension Term.

     (iv)  NOTICE TO LESSOR AND LESSEE.  After the Base Rent for the Extension 
Term has been set, the appraisers shall immediately notify Lessor and Lessee, 
and Lessor and Lessee shall immediately execute an amendment to this Lease 
stating the Base Rent.

58.  HAZARDOUS SUBSTANCES.  Lessee acknowledges that Lessor has delivered to 
Lessee a copy of that certain Environmental Site Assessment dated September 
22, 1995 and Subsurface Investigation Report dated October 11, 1995, prepared 
by AllWest Environmental, Inc. (collectively, "Environmental Reports"). The 
Environmental Reports indicate the presence of trace amounts of a Hazardous 
Substance in the groundwater beneath the Building ("Existing Hazardous 
Substance"). Lessor shall be responsible for any investigation or remediation 
of the Existing Hazardous Substance required by any applicable governmental 
agency having jurisdiction and Lessee shall not be required to pay any costs 
in connection with any such investigation or remediation. Nothing contained 
herein shall absolve Lessee from any responsibility for Hazardous Substances 
used, generated, stored, disposed, released or transported by Lessee on or 
from the Industrial Center.

59.  ASSIGNMENT AND SUBLETTING.  Notwithstanding anything to the contrary 
contained in paragraph 12.1(b) above, the transfer, on a cumulative basis, of 
fifty (50%) percent or more of the voting control of Lessee shall constitute 
a change in control for purposes of this Lease, EXCEPT, in the event Lessee 
becomes a publically traded company through an initial and subsequent public 
offerings AND Steve Willens remains as President of Lessee, then for purposes 
of this Lease, the transfer, on a cumulative basis, of seventy-five (75%) 
percent or more of the voting control of Lessee shall constitute a change in 
control.

                               DEFERRED COMPENSATION PLAN

This Deferred Compensation Plan (the "Plan"), is made by and between 
Livingston Enterprises, Inc., located at 6920 Koll Center Parkway, #220, 
Pleasanton, California ("Company"), and Jerrold Livingston ("Livingston"), an 
individual residing at 1844 Kenpark Ct., San Jose, California.

WHEREAS, Livingston is a founder, and has served as the Company's Chairman of 
the Board from inception to 1995, and its President from inception to 1994;

WHEREAS, During this time frame, Livingston has received no salary for the 
time spent in pursuit of the growth of the Company, and for the assumption of 
the risk of liability inherent in such pursuit;

WHEREAS, The Board of Directors wishes to recognize the contributions of 
Livingston to the success of the Company, and his forbearance of full 
compensation for his past services provided on behalf of the Company;

NOW THEREFORE, In consideration of Livingston's past services provided on 
behalf of the Company, the Company hereby agrees to provide to Livingston, 
the deferred compensation package as set forth below:

1. DEFERRED COMPENSATION PLAN--This Deferred Compensation Plan is established 
as an unfunded individual plan, created by the Company for the benefit of 
Jerrold Livingston. It is created to compensate Livingston for his past 
services provided on behalf of the Company, from the period of time from 
September 12, 1986 until September 28, 1995. Livingston resigned as President 
and Chief Executive Officer on October 26, 1994, and resigned as Chairman on 
September 28, 1995. Livingston remains a director and over 10% shareholder of 
the Company. This Plan is not intended to meet the funding, employee coverage 
and other requirements of a "qualified" plan under Section 401(a) of the 
Internal Revenue Code.

2. PAYMENT OF BENEFITS--Commencing on January 1, 1996, the Company agrees to 
pay to Livingston, the aggregate amount of $90,000, to be paid in twenty-four 
(24) bi-monthly installments, in accordance with the Company's standard 
payroll procedures. Thereafter, the Company shall continue to make such 
payments until: (1) January 1, 2005, or (2) the lock-up period terminates in 
connection with the closing of an initial public offering of the Company's 
common stock, or (3) the closing of a merger or sale of the Company; 
whichever is sooner. The parties agree, however, that the first $90,000 is 
guaranteed, notwithstanding the occurrence of numbers (2) or (3) above. In the 
event of (1), (2) or (3) above, this Plan shall immediately terminate and be 
of no further force or effect.

3. TAX IMPACT--The Company makes no representations or warranties to 
Livingston concerning the Federal or California state tax consequences of this 
Plan. Each party agrees

<PAGE>

that it shall be responsible for its own tax consequences and to satisfy or 
pay when due, all tax obligations which may arise as a result of the 
implementation of this Plan.

4. PARTIES IN INTEREST/NO ASSIGNMENT--This Plan shall be binding upon and 
inure to the benefit of the Company, its successors in interest, and 
Livingston and his heirs, executors, administrators and legal 
representatives. The rights and other benefits created under this Plan shall 
not be assigned, transferred, pledged or encumbered except by will or by the 
laws of descent and distribution.

5. GOVERNING LAW--This Plan shall be construed in accordance with and is 
governed by the laws of the State of California.

IN WITNESS WHEREOF, the parties hereto have executed this agreement on 
May 2, 1996.

|                                                                             |
|   $5,000,000.00       APRIL 30, 1996    MARCH 1, 1998    77-0127305         |
|_____________________________________________________________________________|


On the Maturity Date, as stated above, for value received, the undersigned 
promise(s) to pay to the order of COMERICA BANK-CALIFORNIA ("Bank"), at any 
office of the Bank in the State of California, FIVE MILLION AND NO/100 
Dollars (U.S.) (or that portion of it advanced by the Bank and not repaid as 
later provided) with interest until maturity, whether by acceleration or 
otherwise, or an Event of Default, as later defined, at a per annum rate 
equal to the Bank's base rate from time to time in effect PLUS 0.00% per 
annum and after that at a rate equal to the rate of interest otherwise 
prevailing under this Note plus 3% per annum (but in no event in excess of 
the maximum rate permitted by law). The Bank's "base rate" is that annual 
rate of interest so designated by the Bank and which is changed by the Bank 
from time to time. Interest rate changes will be effective for interest 
computation purposes as and when the Bank's base rate changes. Interest shall 
be calculated on the basis of 360-day year for the actual number of days the 
principal is outstanding. Accrued interest on this Note shall be payable on 
the 1ST day of each MONTH commencing JUNE 1, 1996, until the Maturity Date 
when all amounts outstanding under this Note shall be due and payable in 
full. If the frequency of interest payments is not otherwise specified, 
accrued interest on this Note shall be payable monthly on the first day of 
each month. If any payment of principal or interest under this Note shall be 
payable on a day other than a day on which the Bank is open for business, 
this payment shall be extended to the next succeeding business day and 
interest shall be payable at the rate specified in this Note during this 
extension. A late payment charge equal to 5% of each late payment may be 
charged on any payment not received by the Bank within 10 calendar days after 
the payment due date, but acceptance of payment of this charge shall not 
waive any Default under this Note.

The principal amount payable under this Note shall be the sum of all advances 
made by the Bank to or at the request of the undersigned, less principal 
payments actually received in cash by the Bank. The books and records of the 
Bank shall be the best evidence of the principal amount and the unpaid 
interest amount owing at any time under this Note and shall be conclusive 
absent manifest error. No interest shall accrue under this Note until the 
date of the first advance made by the Bank; after that interest on all 
advances shall accrue and be computed on the principal balance outstanding 
from time to time under this Note until the same is paid in full.

This Note and any other indebtedness and liabilities of any kind of the 
undersigned (or any of them) to the Bank, and any and all modifications, 
renewals or extensions of it, whether joint or several, contingent or 
absolute, now existing or later arising, and however evidenced (collectively, 
"Indebtedness") are secured by and the Bank is granted a security interest in 
all items deposited in any account of any of the undersigned with the Bank 
and by all proceeds of these items (cash or otherwise), all account balances 
of any of the undersigned from time to time with the Bank, by all property of 
any of the undersigned from time to time in the possession of the Bank and by 
any other collateral, rights and properties described in each and every deed 
of trust, mortgage, security agreement, pledge, assignment and other security 
or collateral agreement which has been, or will at any time(s) later be, 
executed by any (or all) of the undersigned to or for the benefit of the Bank 
(collectively "Collateral"). Notwithstanding the above, (i) to the extent 
that any portion of the Indebtedness is a consumer loan, that portion shall 
not be secured by any deed of trust or mortgage on or other security interest 
in any of the undersigned's principal dwelling or any of the undersigned's 
real property which is not a purchase money security interest as to that 
portion, unless expressly provided to the contrary in another place, or (ii) 
if the undersigned (or any of them) has(have) given or give(s) Bank a deed of 
trust or mortgage covering real property, that deed of trust or mortgage 
shall not secure this Note or any other Indebtedness of the undersigned (or 
any of them), unless expressly provided to the contrary In another place.

If the undersigned (or any of them) or any guarantor under a guaranty of all 
or part of the Indebtedness ("guarantor") (i) fail(s) to pay any of the 
indebtedness when due, by maturity, acceleration or otherwise, or fails(s) to 
pay any indebtedness owing on a demand basis upon demand; or (ii) fail(s) to 
comply with any of the terms or provisions of any agreement between the 
undersigned (or any of them) or any such guarantor and the Bank; or (iii) 
become(s) insolvent or the subject of a voluntary or involuntary proceeding 
in bankruptcy, or a reorganization, arrangement or creditor composition 
proceeding, (if a business entity) cease(s) doing business as a going 
concern, (if a natural person) die(s) or become(s) incompetent, (if a 
partnership) dissolve(s) or any general partner of it dies, becomes 
incompetent or becomes the subject of a bankruptcy proceeding or (if a 
corporation of a limited liability company) is the subject of a dissolution, 
merger or consolidation; or (a) if any warranty or representation made by any 
of the undersigned or any guarantor in connection with this Note or any of 
the Indebtedness shall be discovered to be untrue or incomplete; or (b) if 
there is any termination, notice of termination, or breach of any guaranty, 
pledge, collateral assignment or subordination agreement relating to all or 
any part of the Indebtedness; or (c) if there is any failure by any of the 
undersigned or any guarantor to pay when due any of its Indebtedness (other 
than to the Bank) or in the observance or performance of any term, covenant 
or condition in any document evidencing, securing or relating to such 
Indebtedness; or (d) if the Bank deems itself insecure believing that the 
prospect of payment of this Note or any of the Indebtedness is impaired or 
shall fear deterioration, removal or waste of any of the Collateral; or (e) 
if there is filed or issued a levy or writ of attachment or garnishment or 
other like judicial process upon the undersigned (or any of them) or any 
guarantor or any of the Collateral, including without limit, any accounts of 
the undersigned (or any of them) or any guarantor with the Bank, then the 
Bank, upon the occurrence of any of these events (each a "Default"), may at 
its option and without prior notice to the undersigned (or any of them), 
declare any or all of the Indebtedness to be immediately due and payable 
(notwithstanding any provisions contained in the evidence of it to the 
contrary), sell or liquidate all or any portion of the Collateral, set off 
against the Indebtedness any amounts owing by the Bank to the undersigned (or 
any of them), charge interest at the default rate provided in the document 
evidencing the relevant Indebtedness and exercise any one or more of the 
rights and remedies granted to the Bank by any agreement with the undersigned 
(or any of them) or given to it under applicable law. In addition, if this 
Note is secured by a deed of trust or mortgage covering real property, then 
the trustor or mortgagor shall not mortgage or pledge the mortgaged premises 
as security for any other Indebtedness or obligations. This Note, together 
with all other Indebtedness secured by said deed of trust or mortgage, shall 
become due and payable immediately, without notice, at the option of the 
Bank, (a) if said trustor or mortgagor shall mortgage or pledge the mortgaged 
premises for any other Indebtedness or obligations or shall convey, assign or 
transfer the mortgaged premises by deed, installment sale contract 
instrument, or (b) if the title to the mortgaged premises shall become vested 
in any other person or party in any manner whatsoever, or (c) if there is any 
disposition (through one or more transactions) of legal or beneficial title 
to a controlling interest of said trustor or mortgagor. All payments under 
this Note shall be in immediately available United States funds, without 
setoff or counterclaim.

If this Note is signed by two or more parties (whether by all as makers or by 
one or more as an accommodation party or otherwise), the obligations and 
undertakings under this Note shall be that of all and any two or more jointly 
and also of each severally. This Note shall bind the undersigned, and the 
undersigned's respective heirs, personal representatives, successors and 
assigns.

The undersigned waive(s) presentment, demand, protest, notice of dishonor, 
notice of demand or intent to demand, notice of acceleration or intent to 
accelerate, and all other notices and agree(s) that no extension or 
indulgence to the undersigned (or any of them) or release, substitution or 
nonenforcement of any security, or release or substitution of any of the 
undersigned, any guarantor or any other party, whether with or without 
notice, shall affect the obligations of any of the undersigned. The 
undersigned waive(s) all defenses or right to discharge available under 
Section 3-605 of the California Uniform Commercial Code and waive(s) all 
other suretyship defenses or right to discharge. The undersigned agree(s) 
that the Bank has the right to sell, assign, or grant participations, or any 
interest, in any or all of the Indebtedness, and that, in connection with 
this right, but without limiting its ability to make other disclosures to the 
full extent allowable, the Bank may disclose all documents and information 
which the Bank now or later has relating to the undersigned or the 
Indebtedness. The undersigned agree(s) that the Bank may provide information 
relating to the Note or to the undersigned to the Bank's parent, affiliates, 
subsidiaries and service providers.

<PAGE>


The undersigned agree(s) to reimburse the holder or owner of this Note for 
any and all costs and expenses (including without limit, court costs, legal 
expenses and reasonable attorney fees, whether inside or outside counsel is 
used, whether or not suit is instituted and, if suit is instituted, whether 
at the trial court level, appellate level, in a bankruptcy, probate or 
administrative proceeding or otherwise) incurred in collecting or attempting 
to collect this Note or incurred in any other matter or proceeding relating 
to this Note.

The undersigned acknowledge(s) and agree(s) that there are no contrary 
agreements, oral or written, establishing a term of this Note and agree(s) 
that the terms and conditions of this Note may not be amended, waived or 
modified except in a writing signed by an officer of the Bank expressly 
stating that the writing constitutes an amendment, waiver or modification of 
the terms of this Note. As used in this Note, the word "undersigned" means, 
individually and collectively, each maker, accommodation party, indorser and 
other party signing this Note in a similar capacity. If any provision of this 
Note is unenforceable in whole or part for any reason, the remaining 
provisions shall continue to be effective. THIS NOTE IS MADE IN THE STATE OF 
CALIFORNIA AND SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE 
INTERNAL LAWS OF THE STATE OF CALIFORNIA, WITHOUT REGARD TO CONFLICT OF LAWS

CONSTITUTIONAL ONE, BUT THAT IT MAY BE WAIVED, EACH PARTY, AFTER CONSULTING 
(OR HAVING HAD THE OPPORTUNITY TO CONSULT) WITH COUNSEL OF THEIR CHOICE, 
KNOWINGLY AND VOLUNTARILY, AND FOR THEIR MUTUAL BENEFIT, WAIVES ANY RIGHT TO
