ITEM 1. BUSINESS

  General

     Rainbow Technologies, Inc., a Delaware corporation, (the "Company") is a
leading developer and supplier of computer network security products that secure
the rights to software and other digital content, and that provide privacy and
security for computer network and Internet communications and commerce. In
addition, the Company provides creative, technical and consulting services that
assist clients to transition their business processes to the Internet through
custom, high performance, secure eBusiness solutions.

     The Company's products include: (i) software protection products for (a)
anti-piracy, (b) license management and tracking, and (c) software distribution
over the Internet (the "Software Protection Products"); (ii) information
security products to protect network and satellite communications (the
"Information Security Products"); and (iii) Internet security products for: (a)
accelerated Internet commerce transaction capabilities in a secure environment,
(b) access controls for computer networks including Virtual Private Networks;
and (c) professional services with expertise in eCommerce, Knowledge Management,
Infrastructure, Security, Business Intelligence, Wireless Computing, and
Business Consulting (the "Internet Products and Services").

     The Company's principal offices and subsidiaries are located in North
America, Europe and Asia. Unless the context otherwise requires, the term
"Company" refers to Rainbow Technologies, Inc. and its subsidiaries.

  Industry Background

     Since its inception in 1984, the Company has been the leading developer and
supplier of proprietary security products that prevent unlicensed use and piracy
of software, and products that protect the confidentiality of digital content
transmitted over telecommunications systems. The Company applies "encryption"
technology in all of its security products. Encryption is the process of making
data indecipherable to anyone other than authorized users. The computer and
software industries have evolved from a market

                                        2
<PAGE>   3

comprised primarily of stand-alone personal computers and single licensed
software programs to a market where computers are connected to networks,
including the Internet, and software licenses are purchased for multiple users
within entire enterprises. The Company has kept pace with the evolving market by
applying its encryption expertise to computer security products and solutions
that correspond to market changes.

     The Company believes that the increased use and acceptance of computer
network and Internet communications to distribute Web-based content and conduct
electronic commerce have caused computer network security to become a paramount
business concern. The Company also believes that business needs for secure,
reliable and scalable computer network and Internet communications provide a
substantial market opportunity for the Company's security products and services.
A recent industry report from International Data Corporation (IDC) estimates
that the number of Internet users will grow from 97 million in 1998 to 320
million by 2002 with commensurate growth in electronic commerce from $32 billion
to $426 billion over that same period. In addition, the Company believes that
the market for the electronic delivery of digital content will continue to grow
rapidly. For example, IDC estimates that the worldwide market for Internet
software distribution will increase from approximately $200 million in 1997 to
approximately $5.9 billion by 2001, a 133% compound annual growth rate.

     The Company expects to take advantage of the anticipated explosive growth
in Internet commerce and communications by expanding its market and product
focus to improve and broaden its encryption technology to offer new computer
network security products and services supporting Internet commerce and
communications.

     During 1999, the Company acquired three companies which provide
professional services with expertise in eCommerce, Knowledge Management,
Infrastructure, Application Development, ERP Integration, Security, Business
Intelligence, Wireless Computing and Business Consulting. The Company helps
companies transition their business processes to the Internet through custom,
high performance, secure eBusiness solutions.

     Intranets, Extranets and Websites (collectively "Internet Applications")
provide companies with a new set of tools for improving basic business processes
such as communications, data transmission, marketing, transaction processing and
customer service. An Intranet enables a company's employees to receive corporate
information and training efficiently, communicate through e-mail, use the
internal network's business application and access proprietary information and
legacy databases. An Extranet can extend part or all of the functionality of a
secure Intranet to selected business partners outside of the company, such as
customers, suppliers or distributors. On the consumer side, Websites support the
full cycle of customer interaction with a brand. Websites can present
advertising and marketing materials in new and compelling fashions, display
products and services in electronic catalogs, offer products and services for
sale online, process transactions and fulfill orders, provide customers with
rapid and accurate responses to their questions and gather customer feedback
efficiently.

     Businesses are rapidly adopting Internet Applications. Companies
implementing Internet Applications often must rely on fundamentally new business
approaches because these solutions utilize new technologies and allow companies
to implement a broad scope of business process improvements. Businesses seeking
to realize the benefits provided by Internet Applications face a formidable
series of challenges presented by the need to link business strategy with new
and rapidly changing technologies and continuously updated content. Before
creating an Intranet, Extranet or Website, a company must first conduct a
thorough needs assessment to review its strategic business requirements and
compare them to the capabilities of its existing processes and systems. Next,
the company must design the solution and develop an implementation plan. The
implementation, establishment and maintenance of the solution will require
significant technical expertise in a number of areas, such as electronic
commerce systems, security and privacy technologies, application and database
programming, mainframe and legacy integration technologies and advanced user
interface and multimedia production.

     To perform the multitude of Internet professional services, a company would
have to make substantial commitments of time, money and technical personnel to
keep current with rapidly evolving technologies, content presentation techniques
and competitors' offerings. Professionals with the requisite strategic,
technical
                                        3
<PAGE>   4

and creative skills are often in short supply and many organizations are
reluctant to expand their internal information systems or marketing departments
for particular engagements at a time when they are attempting to minimize fixed
costs to increase returns on investment. At the same time, external economic
factors encourage organizations to focus on their core competencies and limit
workforces in the information technology management area. Accordingly, many
businesses have chosen to outsource a significant portion of the design,
development and maintenance of their Intranets, Extranets and Websites to
independent professionals. These independent professionals can leverage
accumulated strategic, technical and creative talent and track developments in a
field characterized by extremely short technology, process and content
lifecycles.

     The Company believes that the rapidly increasing demand for Internet
applications has created a significant market opportunity for its unique
services.

solutions to digital applications and unique processes enable the Company to
differentiate its offering of services from other consulting entities.

SOFTWARE PROTECTION PRODUCTS

     The Company's Software Protection Products combine sophisticated hardware
and software encryption technology to prevent the illegal distribution and use
of software. When software is protected by the Company's Sentinel suite of
hardware products (the "key"), the software program sends queries to the key
that is attached to the parallel port of the computer. The key immediately
evaluates each query and responds. The correct response ensures that standard
operation of the software will continue without interruption. If the key is not
present, the software will not operate. The keys incorporate the Company's
proprietary "algorithms" programmed into Company designed "ASIC" computer chips.
An algorithm is a mathematical procedure for manipulating digital information
with the intent of securing the information. An "ASIC" or "Application Specific
Integrated Circuit" is a logic circuit designed for a specific usage and
implemented in an integrated circuit. Once Sentinel protection is implemented,
developers need only include a Sentinel key with each software package shipped.
The end-user installs the software as usual, then simply plugs the enclosed
Sentinel key into the appropriate port on their computer.

     The Company also offers software-based products that provide software
license management and that provide Software Protection Products over the
Internet. These products offer software developers greater flexibility in how
their products are licensed and distributed.

     The Company's Software Protection Products include:

by subcontractors in the United States, Asia and Europe from components
specified and approved by the Company. The components include ASIC chips,
standard computer memory chips and standard computer hardware parts. The Company
maintains control over the purchasing of materials and the planning and
scheduling of the manufacturing and assembly process. After assembly of the
components, the keys are delivered to the Company's facilities in the United
States and Europe where the products are inspected, tested and configured. The
Company believes that it is the lowest cost producer of software protection
products and believes that this will continue to be a competitive advantage.

     INFORMATION SECURITY PRODUCTS

     For its Information Security Products, the Company's manufacturing
operations include the testing of ASICs and the final assembly and testing of
its satellite and network communications products.

     The Company has specific encryption technology embedded into ASIC circuits
that are fabricated to the Company's specifications by ASIC circuit
manufacturers. The Company currently has relationships with three such ASIC
circuit manufacturers. These ASIC circuits are processed to the specifications
of the U.S. Government and the Company. Any interruption in the availability of
these ASIC circuits could have a material adverse effect on the operations of
the Company.

     The Company currently has a manufacturing relationship with Raytheon
Systems Company to manufacture the Company's principal Information Security
Products. Raytheon assumed the obligations of AlliedSignal, Inc., to manufacture
the Information Security Products in September 1998. Raytheon is the sole
supplier of the product. The manufacturing agreement expired in December 1999.
The Company is currently
                                        9
<PAGE>   10

working with other companies to provide additional manufacturing sources for
product. Any interruption in the availability of the product could have a
material adverse effect on the operations of the Company. Raytheon has also
assumed the obligation to complete the development of an enhanced version of the
Company's principal Information Security Products.

     Prior to the expiration of the manufacturing agreement with Raytheon, the
Company established a manufacturing relationship with EFTC to manufacture the
Company's principal Information Security products. EFTC is the sole supplier of
the products. The manufacturing agreement expires in December, 2000. The Company
is currently working with other companies to provide additional manufacturing
sources for the products. Any interruption in the availability of the products
would have a material adverse affect on the operations of the Company.

     INTERNET SECURITY PRODUCTS

     The Company's Internet Security Products are manufactured by subcontractors
in the United States from components specified and approved by the Company. The
components include ASIC chips, standard computer related chips and standard
computer hardware parts. The Company maintains control over the purchasing of
materials and the planning and scheduling of the manufacturing and assembly
process. After assembly of the components, the products are delivered to the
Company's facilities in the United States where the products are inspected,
tested and configured.

     The Company currently has one supplier of the ASIC chip used in the
Company's Internet Security Products. The Company currently has a relationship
with a chip supplier that has multiple foundries available to produce the ASIC
chip. If the supplier is unable to fulfill the Company's requirements, the
Company may experience an interruption in the production of its Internet
Security Products until an alternative source of supply is developed. The
Company maintains a six-month inventory of ASIC chips in order to limit the
potential for such an interruption. The Company believes that there are a number
of companies capable of commencing the manufacture of its ASIC chips within six
months of such an interruption.

BACKLOG

     The Company manufactures its Software Protection Products and Internet
Products and Services on the basis of its forecast of near-term demand and
maintains inventory in advance of receipt of firm customer orders. Customer
orders are generally placed on an "as needed" basis and are usually shipped by
the Company within one week after receipt of the order. Recently, the Company
has received several multi-million dollar orders for its Internet Products and
Services with deliveries scheduled over six to nine months.

     As of December 31, 1999, the backlog for both of the Company's Information
and Internet Security Products is approximately equal to 1999 revenues for these
business segments.

INTELLECTUAL PROPERTY

     The Company believes that the value of its security products is dependent
upon its proprietary algorithms and encryption techniques remaining "trade
secrets." The Company has obtained copyright protection on certain of its
products and trademark protection for certain of its trade names. The Company
also owns several patents for its Information Security Products, and the Company

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
FINANCIAL CONDITION

     The following is management's discussion and analysis of certain
significant factors that have affected the profitability of the Company's
business segments (Software Protection Products, Information Security Products,
and Internet Products and Services) and its consolidated results of operations
and financial condition during the periods included in the accompanying
consolidated financial statements. The following should be read in conjunction
with the consolidated financial statements and related notes.

     ACQUISITIONS

     On October 22, 1999, the Company completed the acquisition of InfoCal LLC
(InfoCal). InfoCal creates collaborative intranet/extranet applications,
knowledge portals and distance learning applications and specializes in
messaging strategy migration and implementation. The total transaction value was
$3.5 million, including $3 million paid in cash and 36,530 shares of Rainbow
common stock valued at $500,000. In addition to the initial consideration, there
is contingent consideration of up to $500,000 in each of the 2000 and 2001
calendar years. The contingent payments are based upon achievement of certain
financial, revenue and strategic goals. Any additional consideration will be
recorded as goodwill. This acquisition has been accounted for using the purchase
method of accounting. Approximately $3.5 million was allocated to goodwill. The
goodwill is being amortized on a straight-line basis over ten years.

     On September 16, 1999, the Company completed the acquisition of InfoSec
Labs, Incorporated (InfoSec). InfoSec has core competency in both enterprise and
internet security solutions and is renowned for

                                       14
<PAGE>   15

its security assessment and education programs. The total transaction value was
$3.1 million, including $1.6 million paid in cash and 120,209 shares of Rainbow
common stock valued at $1.5 million. This acquisition has been accounted for
using the purchase method of accounting. Approximately $3.1 million was
allocated to goodwill and is being amortized on a straight-line basis over ten
years.

     On May 12, 1999, the Company completed the acquisition of Systematic
Systems Integration (Systematic) for an initial purchase price of $9.6 million
in cash with an additional cash payment of $1.5 million accrued for at December
31, 1999 and paid in January 2000. In addition, the purchase agreement provides
for contingent payments of up to $1.7 million. These payments are based upon the
attainment of certain revenue and gross margin goals for calendar year 2000.
This acquisition has been accounted for using the purchase method of accounting.
The entire purchase price has been allocated to goodwill and any additional
consideration paid will also be recorded as goodwill. The goodwill is being
amortized on a straight-line basis over ten years. Systematic is a
California-based eCommerce integration services firm that enables companies to
seamlessly integrate diverse software and hardware platforms, communication
systems and Internet technologies.

     On February 26, 1998, the Company completed the acquisition of Wyatt River
Software, Inc. (Wyatt). Wyatt develops, manufactures, and markets network
license management software. The total transaction value was $9 million,
including $3.9 million paid in cash to Wyatt stockholders and $5.1 million in
assumed liabilities. This acquisition has been accounted for under the purchase
method of accounting. The purchase price has been allocated based upon estimated
fair values at the date of acquisition. Approximately $1.5 million of the
purchase price was written off as in-process research and development at the
acquisition date, approximately $2.7 million was allocated to developed
software, and the remaining $4.8 million was allocated to goodwill and other
intangibles. The goodwill and other intangibles are being amortized on a
straight-line basis over five years. At December 31, 1998, the Company wrote-off
developed software related to the Wyatt acquisition which had a net book value
of $427,000. This amount has been included in research and development expense
for the year ended December 31, 1998.

     On March 6, 1998, the Company entered into an agreement to purchase certain
assets from Elan Computer Group, Inc. (Elan) for $800,000. The assets included
Elan's license manager software technology, which the Company had previously
licensed from Elan, and Elan's end-user maintenance and support relationships.
In connection with the transaction, the Company entered into a Litigation
Cooperation Agreement with Elan in connection with a patent infringement lawsuit
entitled Globetrotter Software, Inc. vs. Elan Computer Group, Inc. No. 97-4176CW
which is currently pending in the United States District Court for the Northern
District of California. The action claims that the Elan technology infringes
upon patents owned by Globetrotter. The lawsuit is deemed to include any and all
claims made now or in the future by Globetrotter Software, Inc. Prior to the
asset purchase agreement with Elan, the Company had an investment in Elan of
$1,320,000. The Company owned less than 20% of Elan's stock and accounted for
the investment under the cost method. During the first quarter of fiscal 1998,
the Company wrote-off its investment in Elan, as it was determined that the
Company's original investment was fully impaired.

     In October 1997, the Company acquired certain assets from AlliedSignal,
Inc. for approximately $7 million in cash comprising AlliedSignal's "KIV-7"
information security product line. The Company is the sole supplier of KIV-7 to
various agencies of the U.S. Government. Simultaneous with the closing of the
asset purchase transaction, the Company entered into a manufacturing and
development agreement with AlliedSignal whereby Allied-Signal was to manufacture
current KIV-7 products for the Company and complete the development of an
enhanced version of the KIV-7 product. Raytheon assumed this manufacturing and
development agreement in September, 1998.

     In May 1997, the Company completed its obligations pursuant to a Stock
Purchase Agreement entered into in March 1996 which resulted in the Company
investing approximately $6 million in QMT. In the fourth quarter of 1998, the
Company determined that the aggregate estimated future undiscounted operating
cash flows of QMT were less than the carrying amount of long-lived assets
related to QMT. Based on its evaluation, the Company determined the assets with
a carrying value of $6.1 million were impaired and wrote them down by $3,942,000
to the estimated fair value. Fair value was based on estimated discounted future
operating cash

                                       15
<PAGE>   16

flows of QMT. The charge had no impact on the Company's 1998 cash flows or its
ability to generate cash flows in the future. As a result of the charges,
depreciation and amortization expense related to those assets will decrease in
future periods. As of December 31, 1999, the Company owns a 51% interest in QMT
and accordingly recognizes a minority interest share in its losses. QMT, located
in Albuquerque, New Mexico owns an exclusive worldwide license from Sandia
National Laboratories for the commercial use and exploitation of a patented
pulsed power ion beam materials treatment technology known as "IBEST."

     At December 31, 1999, the Company performed a review for impairment of the
long-lived assets of QMT. The aggregate undiscounted cash flows estimated to be
generated by QMT during the life of its long-lived assets are greater than their
$2.1 million carrying value indicating no impairment exists at December 31,
1999. However, there is uncertainty related to the estimates used to determine
these undiscounted cash flows. The most significant and uncertain of these
estimates is future revenues. A significant shortfall from these revenue
projections could result in these assets becoming impaired as early as June 30,
2000. The Company anticipates performing impairment reviews related to the
long-lived assets of QMT on a quarterly basis in order to monitor the
achievement of its revenue projections.

     Software Protection Products revenue for the year ended December 31, 1999
increased 4% to $59,400,000 as compared with 1998. Revenues from international
markets increased by 22% while revenues from domestic markets decreased by 7%.
The increase in revenues from international markets was primarily attributable
to an increase in sales generated through the addition of offices in Australia,
Taiwan and China, and the Company's reorganization of its international
operations. The average selling price per product for the year ended December
31, 1999 increased approximately 2% from the year ended December 31, 1998. Unit
volume for the year ended December 31, 1999 increased by 2% as compared with
1998.

     During the year ended December 31, 1999, approximately 18% of the Company's
Software Protection Products revenue was subject to currency fluctuations, down
from 19% in 1998. Software Protection Products revenue in the future is expected
to continue to be affected by foreign currency rate fluctuations.

     Information Security Products revenue for the year ended December 31, 1999
decreased 10% to $45,297,000, as compared with 1998. The revenue decline was
primarily due to a shift in government spending from security products to
defense products.

     Internet Products and Services revenue for the year ended December 31, 1999
increased 857% to $16,175,000 as compared with 1998. The revenue growth was
primarily due to the increase in sales of Cryptoswift products and revenues
generated through the acquisition of Systematic.

     Gross profit from Software Protection Products for the year ended December
31, 1999 was 70% of revenues compared with 71% of revenues for the year ended
December 31, 1998.

     Gross profit from Information Security Products for the year ended December
31, 1999 was 15% of revenues compared with 22% of revenues for the year ended
December 31, 1998. The decrease in gross profit was due to the change in mix
from more profitable product contracts to less profitable research and
development contracts.

     Gross profit from Internet Products and Services for the year ended
December 31, 1999 was 50% of revenues compared with 54% of revenues for the year
ended December 31, 1998. The decrease in gross profit was due to higher costs
associated with the eCommerce integration services revenues.

     There can be no assurance that the Company will improve or maintain the
level of gross profit percentages it experienced during the year ended December
31, 1999.

     Consolidated selling, general and administrative expenses for the year
ended December 31, 1999 were 27% of revenues compared with 24% of revenues for
the year ended December 31, 1998. Selling, general and administrative expenses
for the year ended December 31, 1999 increased by $6,593,000 as compared with
1998. This increase was primarily due to additional staff and higher marketing
expenses for new internet security product introductions and the opening of
sales offices in Asia.
                                       16
<PAGE>   17

     Total research and development expenses for each of the years ended
December 31, 1999 and 1998 was 9% of revenues. Current research and development
activities are primarily focused on additional ASIC development for future
products and the adaptation of the Company's existing internet security products
to additional software operating environments and computer platforms.

     Goodwill amortization in 1999 decreased by $356,000 to $2,438,000 as
compared with 1998, due to a lower average goodwill balance in 1999 as compared
to 1998, resulting from the write-off of goodwill related to QMT at December 31,
1998, partially offset by the amortization of goodwill related to acquisitions
in 1999. For the year ended December 31, 1999, goodwill amortization was 2% of
revenues compared to 3% of revenues for the year ended December 31, 1998.

     Interest income for the year ended December 31, 1999, decreased by 37% to
$862,000, as compared with 1998, primarily due to lower average cash and cash
equivalent balances during 1999.

     At December 31, 1999, the Company held a 51% interest in one of its
subsidiaries, QMT, referred to as Ion Beam Surface Treatment in the Company's
financial statements. For the year ended December 31, 1999, QMT incurred a
$1,869,000 loss, including a write-off of impaired long-lived assets of
$144,000. The Company recognized a minority interest share in the 1999 loss of
approximately $880,000.

     During the year ended December 31, 1999, the Company incurred foreign
currency gains of $752,000, primarily due to dollar denominated deposit accounts
maintained in Europe. During the year ended December 31, 1998, the Company
recognized foreign currency losses of $90,000, also primarily due to dollar
denominated deposit accounts maintained in Europe. Such foreign currency gains
and losses result from the movement in the value of the U.S. dollar against the
functional currencies used by the Company's foreign subsidiaries.

     The effective tax rate was 38% for the year ended December 31, 1999
compared to 72% for the year ended December 31, 1998. The effective tax rate for
1998 was negatively affected due to non-deductibility of the charges related to
acquired in-process research and development, the non-deductibility of the
write-off of a long-term investment, and asset impairment charges related to
QMT. Excluding the effect of these charges, the effective tax rate was 43% for
the twelve months ended December 31, 1998.

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

     Software Protection Products revenue for the year ended December 31, 1998
decreased 5% to $57,238,000 as compared with 1997. The decline in revenue was
primarily due to the economic problems in Asia and other emerging markets.
Revenues in European markets increased 9% in 1998 as compared with 1997. The
average selling price per product for the year ended December 31, 1998 decreased
approximately 7% from the year ended December 31, 1997.

     During the years ended December 31, 1998 and 1997, approximately 19% of the
Company's Software Protection Products revenue was subject to currency
fluctuations. Software Protection Products revenue in the future is expected to
continue to be affected by foreign currency rate fluctuations.

     Information Security Products revenue for the year ended December 31, 1998
increased 48% to $50,236,000, as compared with 1997. The revenue growth was
primarily due to increased shipments of secure network communication products.

     Internet Products and Services revenue for the year ended December 31, 1998
increased 661% to $1,690,000 as compared with 1997. The revenue growth was
primarily due to the adoption of Hewlett Packard and Watchguard as OEM's for the
Company's Internet products.

     Gross profit from Software Protection Products for the year ended December
31, 1998 was 71% of revenues which was consistent with the year ended December
31, 1997. There can be no assurance that the Company will improve or maintain
the level of gross profit percentage it experienced during the year ended
December 31, 1998.

                                       17
<PAGE>   18

     Gross profit from Information Security Products for the year ended December
31, 1998 was 22% of revenues compared with 20% of revenues for the year ended
December 31, 1997. The increase in gross profit was due to the change in mix
from less profitable research and development contracts to more profitable
product contracts.

     Gross profit from Internet Products and Services for the year ended
December 31, 1998 was 54% of revenues compared with 51% of revenues for the year
ended December 31, 1997. The increase in gross profit was due to the decrease in
overall unit costs as a result of the increase in total sales.

     Selling, general and administrative expenses for the years ended December
31, 1998 were 24% of revenues compared with 23% of revenues for the year ended
December 31, 1997. Selling, general and administrative expenses for the year
ended December 31, 1998 increased by $4,642,000 as compared with 1997. This
increase was primarily due to additional staff and higher marketing expenses for
new product introductions in software protection and internet security products
and subsidiary reorganization costs which were primarily related to the
Company's efforts to lower its future effective tax rate.

     Research and development expenses for both years ended December 31, 1998
and 1997 was 9% of revenues. Current research and development activities are
primarily focused on additional ASIC development for future products and the
adaptation of the Company's existing products to additional software operating
environments and computer platforms.

     Goodwill amortization for the year ended December 31, 1998 increased
$1,002,000 as compared with 1997 due to an increase in goodwill resulting from
the 1998 Wyatt acquisition.

     In the fourth quarter 1998, the Company determined that the aggregate
estimated future undiscounted operating cash flows of QMT, a majority owned
subsidiary, referred to as Ion Beam Surface Treatment in the Company's financial
statements, were less than the carrying amount of long-lived assets related to
QMT. Based on its evaluation, the Company determined the assets with a carrying
value of $6,105,000 were impaired and wrote them down by $3,942,000 to the
estimated fair value. Fair value was based on estimated discounted future
operating cash flows of QMT. For the year ended December 31, 1998, the Company
recognized a minority interest share in the loss of QMT.

     During the year ended December 31, 1998, the Company wrote-off $1,500,000
of in-process research and development acquired in Wyatt acquisition.

     Interest income for the year ended December 31, 1998 decreased by 14% to
$1,375,000, as compared with 1997, primarily due to lower average cash and cash
equivalent balances during 1998.

     During the first quarter of fiscal 1998, the Company wrote-off a $1,320,000
investment which was determined to be fully impaired. This amount has been
included in other income (expense), net for the year ended December 31, 1998.

     During the year ended December 31, 1998, the Company incurred foreign
currency losses of $90,000, primarily due to dollar denominated deposit accounts
maintained in Europe. During the year ended December 31, 1997, the Company
recognized foreign currency losses of $167,000, also primarily due to dollar
denominated deposit accounts maintained in Europe. Such foreign currency gains
and losses result from the movement in the value of the U.S. dollar against the
functional currencies used by the Company's foreign subsidiaries.

     The effective tax rate was 72% for the year ended December 31, 1998
compared to 41% for the year ended December 31, 1997. The effective tax rate for
1998 was negatively affected due to non-deductibility of the charges related to
acquired in-process research and development, the non-deductibility of the
write-off of the original investment in Elan, and impairment charges related to
its investment in QMT. Excluding the effect of these charges, the effective tax
rate was 43% for the twelve months ended December 31, 1998.

LIQUIDITY AND CAPITAL RESOURCES

     The Company's principal sources of operating funds have been from
operations and proceeds from sales of the Company's equity securities. The
Company's cash flow from operations during 1999, 1998 and 1997 was $11,127,000,
$12,269,000, and $12,948,000, respectively. The impact of a higher accounts
receivable balance in 1999 was partially offset by amortization and depreciation
and higher accounts payable and accrued liability balances. The impact of a
higher accounts receivable balance in 1998 was offset by the asset impairment
charge related to QMT.

     Net cash used in investing activities for 1999 increased from 1998 due to
the acquisition of Systematic, InfoSec and InfoCal, offset by increased proceeds
from the sale of marketable securities. Net cash used in investing activities
for 1998 increased from 1997 due to the acquisition of Wyatt and increased
proceeds from the sales of marketable securities during 1997.

     The Company intends to use its capital resources to expand its product
lines and for possible acquisitions of additional products and technologies. The
Company has no significant capital commitments or requirements at this time.

     At December 31, 1999 the Company's subsidiaries in France and the
Netherlands carry approximately $9.9 million and $2.7 million, respectively, in
interest earning deposits which may result in foreign exchange gains or losses
due to the fact that the functional currency in those subsidiaries is not the
U.S. dollar.

     Management believes that the effect of inflation on the business of the
Company for the past three years has been minimal.

     The Company believes that its current working capital of $48,936,000 and
anticipated working capital to be generated by future operations will be
sufficient to support the Company's working capital requirements through at
least December 31, 2000.

IMPACT OF YEAR 2000

     Year 2000 problems are the result of computer programs being written using
two digits rather than four to define the applicable year. If not corrected,
many computer applications could fail or create erroneous results by not
recognizing "00" to mean the year 2000.

     In 1999, the Company completed its testing of all critical software and
hardware systems and determined that all are Year 2000 compliant. Vendor
certifications were received from all critical vendors indicating that they were
either currently compliant or that they would be compliant by December 31, 1999.

     The Company has not experienced and does not expect to experience any
significant Year 2000 problems or interruptions. There can be no assurance that
mission critical vendors and customers will not incur a Year 2000 problem or
interruption, but the Company believes adequate computer file backup procedures
and manual operating procedures will enable the continuance of the critical
processes of its business.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     Market risk generally represents the risk that losses may occur in the
values of financial instruments as a result of movements in interest rates,
foreign currency exchange rates and commodity prices. The Company is exposed to
changes in financial market conditions in the normal course of its business due
to its use of certain financial instruments as well as transacting in various
foreign currencies and translation of its foreign subsidiaries financial
statements to the U.S. dollar.

INTEREST RATE RISK

     At December 31, 1999 and 1998, the Company's cash equivalents and
short-term investments included approximately $1.2 million and $6.5 million,
respectively, of fixed income securities. These securities are subject to
interest rate risk and may decline in value when interest rates change. At
December 1999 all of the Company's fixed income securities mature during 2012.
An adverse change of 10% in interest rates would have

                                       19
<PAGE>   20

an immaterial effect on the fair value of these securities. These investments do
not represent a material market risk to the Company. The Company places
substantially all of its interest bearing investments with major financial
institutions and, by policy limits the amount of credit exposure to any one
financial institution. Additionally, the Company does not hold or issue
financial instruments for trading, profit or speculative purposes.

EQUITY PRICE RISK

     The Company holds investments in various available-for-sale equity
securities which are subject to price risk. The fair value of such investments,
as of December 31, 1999 and 1998 was approximately $2 million. The potential
change in the fair value of these investments, assuming a 10% decline in prices
would be approximately $200,000 for 1999 and 1998.

FOREIGN EXCHANGE RATE RISK

     The Company operates internationally and has adopted local currencies as
the functional currencies for its foreign subsidiaries because their principal
economic activities are most closely tied to the respective local currencies.
This exposes the Company to market risk from changes in foreign exchange rates
to the extent that transactions are not denominated in the U.S. dollar. In
consolidation, the Company converts the accounts of its foreign subsidiaries
from the functional currency to the U.S. dollar. As a result the Company faces
the risk that the foreign currencies will have declined in value as compared to
the U.S. dollar, resulting in a foreign currency translation loss. Assuming an
adverse 10% foreign exchange rate fluctuation, the Company would have
experienced translation losses of approximately $2 million for 1999 and 1998.

     The Company's earnings are affected by fluctuations in the value of the U.S
dollar as compared to foreign currencies as a result of the sales of its
products in foreign markets. Assuming an adverse 10% foreign exchange rate
fluctuation, the Company would have had a decrease in net income of
approximately $500,000 and $200,000 for the years ended December 31, 1999 and
1998, respectively. This calculation assumes that each exchange rate would
change in the same direction relative to the U.S. dollar. In addition, to the
direct effects of changes in exchange rates, which are a changed dollar value of
the resulting sales, changes in exchange rates also affect the volume of sales
or the foreign currency sales price as competitors' products become more or less
attractive. The Company's sensitivity analysis of the effects of changes in
foreign currency exchange rates does not factor in a potential change in sales
levels or local currency prices.

                         REPORT OF INDEPENDENT AUDITORS

Board of Directors
Rainbow Technologies, Inc.

     We have audited the accompanying consolidated balance sheets of Rainbow
Technologies, Inc. as of December 31, 1999 and 1998, and the related
consolidated statements of income, shareholders' equity, and cash flows for each
of the three years in the period ended December 31, 1999. Our audits also
included the financial statement schedule listed in the Index at Item 14(a).
These financial statements and the financial statement schedule are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements and the schedule based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Rainbow
Technologies, Inc. at December 31, 1999 and 1998, and the consolidated results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1999, in conformity with accounting principles generally
accepted in the United States. Also, in our opinion, the related financial
statement schedule, when considered in relation to the basic financial
statements taken as a whole, presents fairly, in all material respects, the
information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                               DECEMBER 31, 1999

 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

GENERAL

     Rainbow Technologies, Inc. (the Company) develops, manufactures, programs
and markets products which prevent the unauthorized use of intellectual
property, including software programs; develops and manufactures information
security products for satellite communications; and develops and manufactures
internet security products to provide privacy and security for network
communications. The accompanying financial statements consolidate the accounts
of the Company and its wholly-owned subsidiaries. All significant intercompany
balances and transactions have been eliminated. Certain amounts previously
reported have been reclassified to conform with the 1999 presentation.

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 amounts reported in the accompanying financial
statements. Actual results could differ from those estimates. Significant
estimates made in preparing these financial statements include the allowance for
doubtful accounts, the reserve for inventory obsolescence, accrued warranty
costs, the allowance for deferred tax assets, total estimated contract costs
associated with billed and unbilled contract revenue and revenue projections
used to estimate future cash flow projections to determine recoverability of the
long-lived assets of Quantum Manufacturing Technologies, Inc. ("QMT").

     At December 31, 1999, the Company performed a review for impairment of the
long-lived assets of QMT. The aggregate undiscounted cash flows estimated to be
generated by QMT during the life of its long-lived assets are greater than their
$2.1 million carrying value indicating no impairment exists at December 31,
1999. However, there is uncertainty related to the estimates used to determine
these undiscounted cash flows. The most significant and uncertain of these
estimates is future revenues. A significant shortfall from these revenue
projections could result in these assets becoming impaired as early as June 30,
2000. The Company anticipates performing impairment reviews related to the
long-lived assets of QMT on a quarterly basis in order to monitor the
achievement of its revenue projections.

CASH EQUIVALENTS

     The Company considers all highly liquid investments with an original
maturity of three months or less to be cash equivalents.

MARKETABLE SECURITIES

     All investment securities are considered to be available-for-sale and are
carried at fair value. Management determines classification at the time of
purchase and re-evaluates its appropriateness at each balance sheet date. The
Company's marketable securities consist of tax-exempt and other debt instruments
that bear interest at variable rates. As of December 31, 1999, gross unrealized
losses were $124,000 while gross unrealized losses were $226,000 as of December
31, 1998. There were no material realized gains or losses for the years ended
December 31, 1999, 1998 and 1997. The cost of securities sold is based on the
specific identification method. The Company's portfolio of marketable debt
securities at December 31, 1999 matures during 2012.

SOFTWARE DEVELOPMENT COSTS

     Statement of Financial Accounting Standards No. 86, "Accounting for the
Costs of Computer Software to be Sold, Leased or Otherwise Marketed," requires
capitalization of certain software development costs

                                       F-7
<PAGE>   33
                           RAINBOW TECHNOLOGIES, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1999

subsequent to the establishment of technological feasibility. Based on the
Company's product development process, technological feasibility is established
upon completion of a working model. Amortization of capitalized software
development costs commences when the products are available for general release
to customers and are determined using the straight-line method over the expected
useful lives of the respective products.

     At December 31, 1999 and 1998, the Company had capitalized computer
software costs, net of amortization, of $3,501,000 and $2,182,000, respectively.
Amortization of computer software development costs for the years ended December
31, 1999, 1998 and 1997 amounted to $588,000, $233,000 and $173,000,
respectively. During 1998 and 1997, the Company wrote-off $784,000 and $242,000,
respectively, of previously capitalized computer software development costs
which were determined to be obsolete.

INVENTORIES

     Inventoried costs relating to long-term contracts are stated at the actual
production cost, including pro-rata allocations of factory overhead and general
and administrative costs incurred to date, reduced by amounts identified with
revenue recognized on units delivered. The costs attributed to units delivered
under such long-term contracts are based on the estimated average cost of all
units expected to be produced.

     Inventories other than inventoried costs relating to long-term contracts
are stated at the lower of cost (first-in, first-out basis) or market.

PROPERTY, PLANT AND EQUIPMENT

     Additions to property, plant, equipment and leasehold improvements are
recorded at cost and depreciated on the straight-line method over their
estimated useful lives as follows:

<TABLE>
<S>                                                     <C>
Buildings.............................................       31 years
Furniture.............................................   5 to 7 years
Equipment.............................................   3 to 7 years
Leasehold improvements................................  Term of lease
</TABLE>

INTANGIBLE ASSETS

     Intangible assets consisting of goodwill, product licenses and patents are
amortized using the straight-line method over seven to ten years. Goodwill
represents the excess of purchase price over the estimated fair value of assets
acquired.

LONG-LIVED ASSETS

     In accordance with Statement of Financial Accounting Standards No. 121
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of" (FAS 121), the Company records impairment losses on long-lived
assets used in operations when events and circumstances indicate that the assets
might be impaired and the undiscounted cash flows estimated to be generated by
those assets are less than the carrying amounts of those assets.

REVENUE RECOGNITION

  Software Protection Products and Internet Security Products

     The Company recognizes revenues from product sales at the time of shipment.
Provision is currently made for estimated product returns which may occur under
programs the Company has with certain of its distributors.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1999

  Information Security Products

     Catalog product revenues and revenues under certain fixed-price contracts
calling for delivery of a specified number of units are recognized as deliveries
are made. Revenues under cost-reimbursement contracts are recognized as costs
are incurred and include estimated earned fees in the proportion that costs
incurred to date bear to total estimated costs. Certain contracts are awarded on
a fixed-price incentive fee basis. Incentive fees on such contracts are
considered when estimating revenues and profit rates and are recognized when the
amounts can reasonably be determined. The costs attributed to units delivered
under fixed-price contracts are based on the estimated average cost per unit at
contract completion. Profits expected to be realized on long-term contracts are
based on total revenues and estimated costs at completion. Revisions to contract
profits are recorded in the accounting period in which the revisions are made.
Estimated losses on contracts are recorded when identified. For research and
development and other cost-plus-fee type contracts, the Company recognizes
contract earnings using the percentage-of-completion method. The estimated
contract revenues are recognized based on percentage-of-completion as determined
by the cost-to-cost basis whereby revenues are recognized ratably as contract
costs are incurred.

WARRANTY

     The Company generally warrants its products for one year. An estimate of
the amount required to cover warranty expense on products sold is charged
against income at the time of sale.

ADVERTISING

     The Company expenses the costs of advertising as incurred. Advertising
expense was $3,709,000, $2,857,000 and $2,601,000 for 1999, 1998, and 1997,
respectively.

RESEARCH AND DEVELOPMENT

     Expenditures for research and development are expensed as incurred.

INCOME TAXES

     Deferred taxes are provided for items recognized in different periods for
financial and tax reporting purposes in accordance with Financial Accounting
Standards Board Statement No. 109, "Accounting For Income Taxes."

FOREIGN CURRENCY

     Balance sheet accounts denominated in foreign currency are translated at
exchange rates as of the date of the balance sheet and income statement accounts
are translated at average exchange rates for the period. Translation gains and
losses are accumulated as a separate component of Shareholders' Equity. The
Company has adopted local currencies as the functional currencies for its
subsidiaries because their principal economic activities are most closely tied
to the respective local currencies.

     The Company may enter into foreign exchange contracts as a hedge against
foreign currency denominated receivables. It does not engage in currency
speculation. Foreign currency transaction gains and losses are included in
current earnings. There were no foreign exchange contracts at December 31, 1999
or 1998.

STOCK OPTION PLANS

     Effective January 1, 1996, the Company adopted the disclosure-only
provisions of Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation" (SFAS No. 123) and

                                       F-9

                           RAINBOW TECHNOLOGIES, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1999

accordingly, is continuing to account for its stock-based compensation plans
under Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued
to Employees" and related interpretations. The adoption of SFAS No. 123 had no
impact on the Company's consolidated results of operations or financial
position.

EARNINGS PER SHARE

     Basic earnings per share is computed by dividing income available to common
shareholders by the weighted-average number of common shares outstanding for the
period. Diluted earnings per share reflects the assumed conversion of all
dilutive securities, consisting of employee stock options.

CONCENTRATIONS OF BUSINESS AND CREDIT RISK

     Financial instruments which potentially subject the Company to credit risk
consist principally of trade receivables and interest bearing investments. The
Company performs on-going credit evaluations of its customers and generally does
not require collateral. The Company maintains adequate reserves for potential
losses and such losses, which have historically been minimal, have been included
in management's estimates. The Company places substantially all of its interest
bearing investments with major financial institutions and, by policy, limits the
amount of credit exposure to any one financial institution.

     The Company sells the majority of its Software Protection Products and
Internet Products and Services to software developers and wholesale distributors
throughout North America, Europe and Asia Pacific. The majority of the Company's
Information Security Products are sold to the U.S. Government (Note 3). The U.S.
Government accounted for over 68%, 67%, and 52% of contract revenues in 1999,
1998, and 1997, respectively. In addition, approximately 50% and 67% of contract
accounts receivable and 71% and 73% of unbilled costs and fees at December 31,
1999 and 1998, respectively, were related to the U.S. Government.

     The Company currently has a manufacturing relationship with Raytheon
Systems Company to manufacture the Company's principal Information Security
Products. Raytheon assumed the obligations of AlliedSignal, Inc. to manufacture
the Information Security Products in September 1998. Raytheon is the sole
supplier of the product. The manufacturing agreement expired in December 1999.
The Company is currently working with other companies to provide additional
manufacturing sources for product. Any interruption in the availability of the
product could have a material adverse effect on the operations of the Company.
Raytheon has also assumed the obligation to complete the development of an
enhanced version of the Company's principal Information Security Products.

     Prior to the expiration of the manufacturing agreement with Raytheon, the
Company established a manufacturing relationship with EFTC to manufacture the
Company's principal Information Security products. EFTC is the sole supplier of
the products. The manufacturing agreement expires in December, 2000. The Company
is currently working with other companies to provide additional manufacturing
sources for the products. Any interruption in the availability of the products
would have a material adverse affect on the operations of the Company.

     The Company currently has one supplier of the ASIC chip used in the
Company's Internet Products and Services. The Company currently has a
relationship with a chip supplier that has multiple foundries available to
produce the ASIC chip. If the supplier is unable to fulfill the Company's
requirements, the Company may experience an interruption in the production of
its Internet Products and Services until an alternative source of supply is
developed. The Company maintains a six-month inventory of ASIC chips in order to
limit the potential for such an interruption. The Company believes that there
are a number of companies capable of commencing the manufacture of its ASIC
chips within six months of such an interruption.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
Accounting for Derivative Instruments and Hedging Activities. SFAS No. 133 is
effective for fiscal years beginning after June 15, 2000. SFAS No. 133 requires
that all derivative instruments be recorded on the balance sheet at their fair
value. Changes in the fair value of derivatives are recorded each period in
current earnings or other comprehensive income (loss) depending on whether a
derivative is designed as part of a hedge transaction and, if so, the type of
hedge transaction involved. The Company does not expect that adoption of SFAS
No. 133 will have a material impact on its consolidated financial position or
results of operations.

 2. ACQUISITIONS

     On October 22, 1999, the Company completed the acquisition of InfoCal LLC
(InfoCal). InfoCal creates collaborative intranet/extranet applications,
knowledge portals and distance learning applications and specializes in
messaging strategy migration and implementation. The total transaction value was
$3.5 million, including $3 million paid in cash and 36,530 shares of Rainbow
common stock valued at $500,000. In addition to the initial consideration, there
is contingent consideration of up to $500,000 in each of the 2000 and 2001
calendar years. The contingent payments are based upon achievement of certain
financial, revenue and strategic goals. Any additional consideration will be
recorded as goodwill. This acquisition has been accounted for using the purchase
method of accounting. Approximately $3.5 million was allocated to goodwill and
is being amortized on a straight-line basis over ten years. Results of
operations for InfoCal are included in the Company's consolidated results of
operations beginning on October 22, 1999.

     On September 16, 1999, the Company completed the acquisition of InfoSec
Labs, Inc. (InfoSec). InfoSec has core competency in both enterprise and
internet security solutions and security assessment and education programs. The
total transaction value was $3.1 million, including $1.6 million paid in cash
and 120,209 shares of Rainbow common stock valued at $1.5 million. This
acquisition has been accounted for using the purchase method of accounting.
Approximately $3.1 million was allocated to goodwill and is being amortized on a
straight-line basis over ten years. Results of operations for InfoSec are
included in the Company's consolidated results of operations beginning on
September 16, 1999.

     On May 12, 1999, the Company completed the acquisition of Systematic
Systems Integration (Systematic) for an initial purchase price of $9.6 million
in cash with an additional $1.5 million accrued for at December 31, 1999, and
was paid in January 2000. In addition, the purchase agreement provides for
contingent payments of up to $1.7 million. These payments are based upon the
attainment of certain revenue and gross margin goals for calendar year 2000.
This acquisition has been accounted for using the purchase method of accounting.
The entire purchase price has been allocated to goodwill and any additional
consideration paid will also be recorded as goodwill. The goodwill is being
amortized on a straight-line basis over ten years. Systematic is a
California-based eCommerce integration services firm that enables companies to
seamlessly integrate diverse software and hardware platforms, communication
systems and internet technologies. Results of operations for Systematic are
included in the Company's consolidated results of operations beginning on May
12, 1999.

     On February 26, 1998, the Company completed the acquisition of Wyatt River
Software, Inc. (Wyatt). Wyatt develops, manufactures, and markets network
license management software. The total transaction value was $9 million,
including $3.9 million paid in cash to Wyatt stockholders and $5.1 million in
assumed liabilities. This acquisition has been accounted for under the purchase
method of accounting. The purchase price has been allocated based upon estimated
fair values at the date of acquisition. Approximately $1.5 million of the
purchase price was written off as in-process research and development at the
acquisition date, approximately $2.7 million was allocated to developed
software, and the remaining $4.8 million was allocated to goodwill and other
intangibles. The goodwill and other intangibles are being amortized on a
                                      F-11

straight-line basis over five years. At December 31, 1998 the Company wrote-off
developed software related to the Wyatt acquisition which had a net book value
of $427,000. This amount has been included in research and development expense
for the year ended December 31, 1998. Results of operations for Wyatt were
included in the Company's consolidated results of operations beginning on
February 26, 1998.

     On March 6, 1998, the Company entered into an agreement to purchase certain
assets from Elan Computer Group, Inc. (Elan) for $800,000. The assets included
Elan's license manager software technology, which the Company had previously
licensed from Elan, and Elan's end-user maintenance and support relationships.
In connection with the transaction, the Company entered into a Litigation
Cooperation Agreement with Elan in connection with a patent infringement lawsuit
entitled Globetrotter Software, Inc. vs. Elan Computer Group, Inc. No. 97-4176CW
which is currently pending in the United States District court for the Northern
District of California. The action claims that the Elan technology infringes
upon patents owned by Globetrotter. The lawsuit is deemed to include any and all
claims made now or in the future by Globetrotter Software, Inc. Prior to the
asset purchase agreement with Elan, the Company had an investment in Elan of
$1,320,000. The Company owned less than 20% of Elan's stock and accounted for
the investment under the cost method. During the first quarter of fiscal 1998
the Company wrote-off its investment in Elan, as it was determined that the
Company's original investment was fully impaired.

     In October 1997, the Company acquired certain assets from AlliedSignal,
Inc. for approximately $7 million in cash comprising AlliedSignal's "KIV-7"
information security product line. The Company is the sole supplier of KIV-7 to
various agencies of the U.S. Government. Simultaneous with the closing of the
asset purchase transaction, the Company entered into a manufacturing and
development agreement with AlliedSignal whereby Allied-Signal will continue to
manufacture current KIV-7 products for the Company, and will complete the
development of an enhanced version of the KIV-7 product. Raytheon assumed this
manufacturing and development agreement in September 1998.

     In May 1997, the Company completed its obligations pursuant to a Stock
Purchase Agreement entered into in March 1996 which resulted in the Company
investing approximately $6 million in QMT. QMT, located in Albuquerque, New
Mexico owns an exclusive worldwide license from Sandia National Laboratories for
the commercial use and exploitation of a patented pulsed power ion beam
materials treatment technology known as "IBEST." In the fourth quarter of 1998,
the Company determined that the aggregate estimated future undiscounted
operating cash flows of QMT were less than the carrying amount of long-lived
assets related to QMT. Based on its evaluation, the Company determined the
assets with a carrying value of $6.1 million were impaired and wrote them down
by $3,942,000 to the estimated fair value. Fair value was based on estimated
discounted future operating cash flows of QMT. The FAS 121 charge had no impact
on the Company's 1998 cash flows or its ability to generate cash flows in the
future. As a result of the FAS 121 charges, depreciation and amortization
expense related to those assets will decrease in future periods. As of December
31, 1999, the Company owns a 51% interest in QMT and accordingly recognizes a
minority interest share in its losses. QMT incurred a 1999 loss of approximately
$1.9 million, including a write-off of impaired assets of approximately
$144,000. The Company recognized a minority interest share in the 1999 loss of
approximately $880,000. See Use of Estimates footnote for discussion regarding
the Company's review of QMT long-lived assets for recoverability at December 31,
1999.

 3. GOVERNMENT CONTRACTS

     The Company is both a prime contractor and subcontractor under fixed-price
and cost reimbursement contracts with the U.S. Government (Government). At the
commencement of each contract or contract modification, the Company submits
pricing proposals to the Government to establish indirect cost rates applicable
to such contracts. These rates, after audit and approval by the Government, are
used to settle costs on contracts completed during the previous fiscal year.

                               DECEMBER 31, 1999

     To facilitate interim billings during the performance of its contracts, the
Company establishes provisional billing rates, which are used in recognizing
contract revenue and contract accounts receivable. These provisional billing
rates are adjusted to actual at year-end and are subject to adjustment after
Government audit.

     The Company has unbilled costs and fees of $2,916,000 and $2,740,000 at
December 31, 1999 and 1998, respectively. Based on the Company's experience with
similar contracts in recent years, the unbilled costs and fees are expected to
be collected within one year.

 6. LINE OF CREDIT

     The Company has a $15 million revolving line of credit which expires on
June 7, 2001. At December 31, 1999, there was $6 million outstanding under the
line of credit. The credit line requires that certain financial ratios be
maintained. Interest on the outstanding balance is designated by the Company and
is computed based on either the prime rate, the fluctuating rate of interest
most recently announced by the lender, or at a fixed rate based on 1.25% above
LIBOR, the reserve percentage prescribed by the Board of Governors of the
Federal Reserve System, at each fixed rate term. The interest rate at December
31, 1999 was 7.75%. The Company also pays the lender an unused commitment fee
computed at one-quarter percent of the average daily unused amount of the line
of credit.

 8. FAIR VALUE OF FINANCIAL INSTRUMENTS

     The fair values presented are estimates of the fair value of the financial
instruments at a specific point in time using available market information and
appropriate valuation methodologies. These estimates are subjective in nature
and involve uncertainties and significant judgment in the interpretation of
current market data. Therefore, the fair values presented are not necessarily
indicative of amounts the Company could realize or settle currently. The Company
does not intend to dispose of or liquidate such instruments prior to maturity.

     The carrying values and estimated fair values of the Company's financial
instruments are as follows at December 31:

1998 and 1997 was $1,743,000, $1,628,000 and $1,663,000, respectively.

  Litigation

     In September 1998, a patent infringement action was filed against the
Company by Globetrotter, Inc., alleging that certain of the Company's products
infringe patents owned by Globetrotter. The complaint seeks unspecified monetary
damages and a permanent injunction banning the use of the products alleged to
infringe the Globetrotter patents. The Company believes the claims are without
merit, and will vigorously defend against the claims made in the action. The
Company has filed a counter claim against Globetrotter alleging anti-trust and
unfair competition.

     In July 1998, a patent infringement claim was filed against the Company by
Andrew Pickholtz, alleging that certain of the Company's products infringe
patents owned by Pickholtz. The complaint seeks unspecified

monetary damages. The Company believes the claims are without merit, and will
vigorously defend against the claims made in the action.

     The Company does not believe that any liabilities related to the legal
proceedings to which it is a party are likely to be, individually or in the
aggregate, material to the Company's consolidated condition or results of
operation.

10. STOCK OPTION PLANS

     The Company has elected to follow Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" (APB 25) and related
Interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under SFAS
No. 123 requires use of option valuation models that were not developed for use
in valuing employee stock options. Under APB 25, because the exercise price of
the Company's employee stock options equals the market price of the underlying
stock on the date of grant, no compensation expense is recognized.

     On April 12, 1990, the Board of Directors of the Company approved the
Company's 1990 Stock Option Plan under which non-statutory or incentive stock
options may be granted to key employees and individuals who provide services to
the Company. Up to an aggregate of 450,000 shares of the Company's common stock
were originally authorized for issuance. Options become exercisable and expire
at the discretion of the Board of Directors, although the plan specifies that no
options shall be exercisable prior to 12 months from the date of grant and all
options expire ten years from the date of grant. In June 1993, the shareholders
approved an amendment to the Company's Restated 1990 Stock Option Plan
authorizing the issuance of an additional 450,000 shares of common stock. In May
1995, an additional increase of 750,000 was approved and in June 1997 an
additional increase of 750,000 was approved. As of December 31, 1999 the total
number of shares reserved for issuance under the existing stock option plans
were 3,453,000 and the total number of options available for grant was 255,000.

     The following is a summary of changes in options outstanding pursuant to
the plan for the years ended December 31:

</TABLE>

     The weighted average remaining contractual life of stock options
outstanding at December 31, 1999, 1998 and 1997 was 7.4 years, 7.6 years and 8.0
years, respectively.

     Pro forma information regarding net income and earnings per share is
required by SFAS 123 and has been determined as if the Company had accounted for
its employee stock options under the fair value method of that Statement. The
fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted average
assumptions for 1999, 1998 and 1997: risk free interest rate of 5.6% for 1999,
4.8% for 1998 and 5.7% for 1997; dividend yield of 0% for 1999, 1998 and 1997;
volatility factor of the expected market price of the Company's common stock of
0.51 for 1999, 0.42 for 1998 and 0.39 for 1997; and a weighted-average life of
the option of 4.0 years for 1999, 1998 and 1997.

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options.

     For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows:

<TABLE>

                                                   1999          1998          1997

  Diluted.....................................  $      .54    $      .11    $       .85
</TABLE>

     The results above are not likely to be representative of the effects of
applying SFAS 123 on reported net income or loss for future years as these
amounts reflect the expense for only one to three years vesting.

11. SHAREHOLDER'S RIGHTS PLAN

     In July 1997, the Board of Directors of the Company adopted a Shareholder's
Rights Plan. In doing so, the Board of Directors declared a dividend of one
right (a "Right") for each outstanding share of the Company's Common Stock, as
of August 5, 1997 and subsequently with respect to each subsequent issuance of a
share of Common Stock. Following a "Distribution Date," each holder of a Right
is entitled to purchase, at a stated purchase price, shares of the Company's
Common Stock or other property having a value equal to two times the purchase
price. A Distribution Date will occur on the earlier of (i) the tenth day after
a public announcement that a person other than the Company or its affiliates has
acquired, or obtained the right to acquire, beneficial ownership of 15% or more
of the outstanding Common Stock (such person thereby

becoming an "Acquiring Person"), or (ii) the tenth business day after the date
of the commencement of, or first public announcement of the intent of any person
to commence a tender or exchange offer, the consummation of which would result
in such person becoming an Acquiring Person. Following a Distribution Date, the
Rights of an Acquiring Person are null and void and not exercisable. Outstanding
Rights are redeemable by the Board of Directors at any time prior to a
Distribution Date at a redemption price of $0.01 per Right. The Rights will
expire at the close of business on August 5, 2002, unless earlier exercised by
the holder or redeemed by the Company.

12. INCOME TAXES

     The provision for income taxes consists of the following for the years
ended December 31:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                               DECEMBER 31, 1999

     The Company has restated its Form 10-Q's for the three month periods ended
March 31, June 30, and September 30, 1998. The above quarterly financial data is
derived from the restated Form 10-Q's, as applicable. In September 1998, the
Securities and Exchange Commission issued a letter to the American Institute of
Certified Public Accountants wherein a new suggested valuation method for
in-process research and development determination was provided. The new
valuation method was to be retroactively applied to all acquisitions in 1998.
Accordingly, during the fourth quarter of 1998 the Company performed a new
valuation analysis related to the acquisition of Wyatt in February, 1998 (see
note 2 to the Notes to Consolidated Financial Statements), which resulted in the
Company adjusting the write-off taken in the first quarter of 1998 related to
in-process research and development acquired in the Wyatt acquisition.

     Net income per share is computed independently for each of the quarters
presented and the summation of quarterly amounts may not equal the total net
income per share reported for the year.

RE: CONSUMER PRICE INDEX (C.P.I.) ADJUSTMENT

Dear Bob:

According to the terms of your lease agreement, you have a rent adjustment on
September 1, 1999.

This rental adjustment is based on the change in the Consumer Price Index (CPI)
for the period June 1998 to June 1999. The CPI for this period has increased
2%, representing an increase of $445.00. However, your lease provides for the
increase to be 50% of the comparison index. This will reduce your increase to
$223.00.

Therefore, effective September 1, 1999 your rent will be $22,489.00 per month.
We will send you a statement reflecting the increase.

Sincerely,

SURF MANAGEMENT ASSOCIATES

     2.2  VEHICLE PARKING. Lessee shall be entitled to seventy-seven (77)
vehicle parking spaces, unreserved and unassigned, on those portions of the
Common Areas designated by Lessor for parking. Lessee shall not use more
parking spaces than said number. Said parking spaces shall be used only for
parking by vehicles no larger than full size passenger automobiles or pick-up

Size Vehicles are herein referred to as "Oversized Vehicles." Lessee shall not
park vehicles overnight.

          2.2.1  Lessee shall not permit or allow any vehicles that belong to
or are controlled by Lessee or Lessee's employees, suppliers, shippers,
customers, or invitees to be loaded, unloaded, or parked in areas other than
those designated by Lessor for such activities.

          2.2.2  If Lessee permits or allows any of the prohibited activities
described in paragraph 2.2 of this Lease, then Lessor shall have the right,
without notice, in addition to such other rights and remedies that it may have,
to remove or tow away the vehicle involved and charge the cost to Lessee, which
cost shall be immediately payable upon demand by Lessor.

     2.3  COMMON AREAS--DEFINITION. The term "Common Areas" is defined as all
areas and facilities outside the Premises and within the exterior boundary line
of the Industrial Center that are provided and designated by the Lessor from
time to time for the general non-exclusive use of Lessor, Lessee and of other
lessees of the Industrial Center and their respective employees, suppliers,
shippers, customers and invitees, including parking areas, loading and
unloading areas, trash areas, roadways, sidewalks, walkways, parkways,
driveways and landscaped areas.

     2.4  COMMON AREAS--LESSEE'S RIGHTS. Lessor hereby grants to Lessee, for
the benefit of Lessee and its employees, suppliers, shippers, customers and
invitees, during the term of this Lease, the non-exclusive right to use, in
common with others entitled to such use, the Common Areas as they exist from
time to time, subject to any rights, powers, and privileges reserved by Lessor
under the terms hereof or under the terms of any rules and regulations or
restrictions governing the use of the Industrial Center. Under no circumstances
shall the rights herein granted to use the Common Areas be deemed to include
the right to store any property, temporarily or permanently, in the Common
Areas. Any such storage shall be permitted only by the prior written consent of
Lessor or Lessor's designated agent, which consent may be revoked at any time.
In the event that any unauthorized storage shall occur then Lessor shall have
the right, without notice, in addition to such other rights and remedies that
it may have, to remove the property and charge the cost to Lessee, which cost
shall be immediately payable upon demand by Lessor.

     2.5  COMMON AREAS--RULES AND REGULATIONS. Lessor or such other person(s)
as Lessor may appoint shall have the exclusive control and management of the
Common Areas and shall have the right, from time to time, to establish, modify,
amend and enforce reasonable rules and regulations with respect thereto. Lessee
agrees to abide by and conform to all such rules and regulations, and to cause
its employees, suppliers, shippers, customers, and invitees to so abide and
conform. Lessor shall not be responsible to Lessee for the non-compliance with
said rules and regulations by other lessees of the Industrial Center.

     2.6  COMMON AREAS--CHANGES. Lessor shall have the right, in Lessor's sole
discretion, from time to time:

          (a)  To make changes to the Common Areas, including, without
limitation, changes in the location, size, shape and number of driveways,
entrances, parking spaces, parking areas, loading and unloading areas, ingress,
egress, direction of traffic, landscaped areas and walkways; (b) To close
temporarily any of the Common Areas for maintenance purposes, so long as
reasonable access to the Premises remains available; (c) To designate other
land outside the boundaries of the Industrial Center to be a part of the Common
Areas; (d) To add additional buildings and improvements to the Common Areas;
(e) To use the Common Areas while engaged in making additional improvements,
repairs or alterations to the Industrial Center, or any portion thereof; (f) To
do and perform such other acts and make such other changes in, to or with
respect to the Common Areas and Industrial Center as Lessor may, in the
exercise of sound business judgment, deem to be appropriate.

          2.6.1  Lessor shall at all times provide the parking facilities
required by applicable law and in no event shall the number of parking spaces
that Lessee is entitled to under paragraph 2.2 be reduced.

3.   TERM.

     3.1  TERM. The term of this Lease shall be for three (3) years commencing
on September 1, 1993 and ending on August 31, 1996 unless sooner terminated
pursuant to any provision hereof.

     3.2  DELAY IN POSSESSION. Notwithstanding said commencement date, if for
any reason beyond the reasonable control of the Lessor, Lessor cannot deliver
possession of the Premises to Lessee on said 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 be obligated to pay rent or perform any other
obligation of Lessee under the terms of this Lease, except as may be otherwise
provided in this Lease, until possession of the Premises is tendered to Lessee;
provided, however, that if Lessor shall not have delivered possession of the
Premises within thirty (30) days from said commencement date, Lessee may, at
Lessee's option, by notice in writing to Lessor within ten (10) days thereafter,
cancel this Lease, in which event the parties shall be discharged from all
obligations hereunder; provided further, however, that if such written notice of
Lessee is not received by Lessor within said ten (10) day period, Lessee's right
to cancel this Lease hereunder shall terminate and be of no further force or
effect.

     3.3  EARLY POSSESSION. If Lessee occupies the Premises prior to said
commencement date, such occupancy shall be subject to all provisions of this
Lease, such occupancy shall not advance the termination date, and Lessee shall
pay rent for such period at the initial monthly rates set forth below.

4.   RENT.

     4.1   BASE RENT. Lessee shall pay to Lessor, as Base Rent for the Premises,
without any offset or deduction, except as may be otherwise expressly provided
in this Lease, on the 1st day of each month of the term hereof, monthly payments
in advance of $21,269.00*. See paragraph 47.

*See paragraph #47 herein for rent schedule. There shall be annual C.P.I.
adjustments per Paragraph #46.d herein.

     Rent for any period during the term hereof which is for less than one month
shall be a pro rata portion of the Base Rent. Rent shall be payable in lawful
money of the United States to Lessor at the address stated herein or to such
other persons or at such other places as Lessor may designate in writing.

     4.2  OPERATING EXPENSES. Lessee shall pay to Lessor during the term
hereof, in addition to the base rent, Lessee's share, as hereinafter defined,
of all Operating Expenses, as hereinafter defined, during each calendar year of
the term of this Lease, in accordance with the following provisions:

          (a)  "Lessee's Share" is defined, for purposes of this Lease as 9.6
percent.

          (b)  "Operating Expenses" is defined, for purposes of this Lease, as
all costs incurred by Lessor, if any, for:

               (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,

lighting facilities and fences and gates.

                                      -1-
<PAGE>   8
                  (ee) Security services.

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

            (ii)  The cost of water, gas and electricity to service the Common
Areas.

      (c)   The inclusion of the improvements, facilities and services set forth
in paragraph 4.2(b)(i) of the definition of Operating Expenses 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 this Lease to provide the same or some of them.

      (d)   Lessee's Share of Operating Expenses 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 Operating
Expenses and the same shall be payable monthly or quarterly, as Lessor shall
designate, during each twelve-month period of the Lease term, on the same day as
the Base Rent is due hereunder. In the event that Lessee pays Lessor's estimate
of Lessee's Share of Operating Expenses as aforesaid, 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 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, Lessee shall be entitled to credit the amount of such
overpayment against Lessee's Share of Operating Expenses next falling due. If
Lessee's payments under this paragraph 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 execution hereof
$10,482.00* as security for Lessee's faithful performance of Lessee's
obligations hereunder. If Lessee fails to pay rent or other charges due
hereunder, or otherwise defaults with respect to any provision of this Lease,
Lessor may use, apply or retain all or any portion of said deposit for the
payment of any rent or other charge in default or for the payment of any other
sum to which Lessor may become obligated by reason of Lessee's default, or to
compensate Lessor for any loss or damage which Lessor may suffer thereby. If
Lessor so uses or applies all or any portion of said deposit, Lessee shall
within ten (10) days after written demand therefor deposit cash with Lessor in
an amount sufficient to restore said deposit to the full amount then required of
Lessee. If the monthly rent shall, form time to time, increase during the term
of this Lease, Lessee shall, at the time of such increase, deposit with Lessor
additional money as a security deposit so that the total amount of the security
deposit held by Lessor 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 4. Lessor shall not be required to keep said security
deposit separate from its general accounts. If Lessee performs all of Lessee's
obligations hereunder, said deposit, or so much thereof as has not theretofore
been applied by Lessor, shall be returned, without payment of interest or other
increment for its use, to Lessee (or, at Lessor's option, to the last assignee,
if any, of Lessee's interest hereunder) at the expiration of the term hereof,
and after Lessee has vacated the Premises. No trust relationship is created
herein between Lessor and Lessee with respect to said Security Deposit. *To be
transferred from leases dated 3/2/87, 11/4/87, 2/10/92 and 11/30/92.

6.    USE.

      6.1 USE. The Premises shall be used and occupied only for
offices for company doing technical computer design and manufacturing
and for no other purpose.

      6.2 COMPLIANCE WITH LAW.

            (a) Lessor warrants to Lessee that the Premises, in the state
existing on the date that the Lease term commences, but without regard to the
use for which Lessee will occupy the Premises, does not violate any covenants or
restrictions of record, or any applicable building code, regulation or ordinance
in effect on such Lease term commencement date. In the event it is determined
that this warranty has been violated, then it shall be the obligation of the
Lessor, after written notice from Lessee, to promptly, at Lessor's sole cost and
expense, rectify any such violation. The warranty contained in this paragraph
6.2(a) shall be of no force or effect if, prior to the date of this Lease,
Lessee was an owner or occupant of the Premises and, in such event, Lessor shall
correct any such violation at Lessee's sole cost.

            (b) Except as provided in paragraph 6.2(a) Lessee shall, at Lessee's
expense, promptly comply with all applicable statutes, ordinances, rules,
regulations, orders, covenants and restrictions of record, and requirements of
any fire insurance underwriters or rating bureaus, now in effect or which may
hereafter come into effect, whether or not they reflect a change in policy from
that now existing, during the term or any part of the term hereof, relating in
any manner to the Premises and the occupation and use by Lessee of the Premises
and of the Common Areas. Lessee shall not use nor permit the use of the Premises
or the Common Areas in any manner that will tend to create waste or a nuisance
or shall tend to disturb other occupants of the Industrial Center.

      6.3   CONDITION OF PREMISES.

            (a) Lessor shall deliver the Premises to Lessee clean and free of
debris on the Lease commencement date (unless Lessee is already in possession)
and Lessor warrants to Lessee that the plumbing, lighting, air conditioning,
heating, and loading doors in the Premises shall be in good operating condition
on the Lease commencement date. In the event that it is determined that this
warranty has been violated, then it shall be the obligation of Lessor, after
receipt of written notice from Lessee setting forth with specificity the nature
of the violation, to promptly, at Lessor's sole cost, rectify such violation.
Lessee's failure to give such written notice to Lessor within thirty (30) days
after the Lease commencement date shall cause the conclusive presumption that
Lessor has complied with all of Lessor's obligations hereunder. The warranty
contained in this paragraph 6.3(a) shall be of no force or effect if prior to
the date of this Lease, Lessee was an owner or occupant of the Premises.

            (b) Except as otherwise provided in this Lease, Lessee hereby
accepts the Premises in their condition existing as of the Lease commencement
date or the date that Lessee takes possession of the Premises, whichever is
earlier, subject to all applicable zoning, municipal, county and state laws,
ordinances and regulations governing and regulating the use of the Premise, and
any covenants or restrictions of record, and accepts this Lease subject thereto
and to all matters disclosed thereby and by any exhibits attached hereto. Lessee
acknowledges that neither Lessor nor Lessor's agent has made any representation
or warranty as to the present or future suitability of the Premises for the
conduct of Lessee's business.

7.    MAINTENANCE, REPAIRS, ALTERATIONS AND COMMON AREA SERVICES.

      7.1. LESSOR'S OBLIGATIONS. Subject to the provisions of paragraphs 4.2
(Operating Expenses), 6 (Use), 7.2 (Lessee's Obligations) and 9 (Damage or
Destruction) and except for damage caused by any negligent or intentional act or
omission of Lessee, Lessee's employees, suppliers, shippers, customers, or
invitees, in which event Lessee shall repair the damage. Lessor, at Lessor's
expense, subject to reimbursement pursuant to paragraph 4.2, shall keep in good
condition and repair the foundations, exterior walls, structural condition of
interior bearing walls, and roof of the Premises, as well as the parking lots,
walkways, driveways, landscaping, fences, signs and utility installations of the
Common Areas and all parts thereof, as well as providing the services for which
there is an Operating Expense pursuant to paragraph 4.2. Lessor shall not,
however, be obligated to paint the exterior or interior surface of exterior
walls, nor shall Lessor be required to maintain, repair or replace windows,
doors or plate glass of the Premises. Lessor shall have no obligation to make
repairs under this paragraph 7.1 until a reasonable time after receipt of
written notice from Lessee of the need for such repairs; Lessee expressly waives
the benefits of any statute now or hereafter in effect which would otherwise
afford Lessee the right to make repairs at Lessor's expense or to terminate this
Lease because of Lessor's failure to keep the Premises in good order, condition
and repair. Lessor shall not be liable for damages or loss of any kind or nature
by reason of Lessor's failure to furnish any Common Area Services when such
failure is caused by accident, breakage, repairs, strikes, lockout, or other
labor disturbances or disputes of any character, or any other cause beyond the
reasonable control of Lessor.

      7.2 LESSEE'S OBLIGATIONS.

            (a) Subject to the provisions of paragraphs 6 (Use), 7.1 (Lessor's
Obligations), and 9 (Damage or Destruction), Lessee, at Lessee's expense, shall
keep in good order, condition and repair the Premises and every part thereof
including, without limiting the generality of the foregoing, electrical and
lighting facilities and equipment within the Premises, fixtures, interior walls
and interior surfaces of exterior walls, ceiling, windows, doors, plate glass,
and skylights located within the Premises. Lessor reserves the right to procure
and maintain the ventilating and air conditioning system maintenance contract
and if Lessor so elects, Lessee shall reimburse Lessor, upon demand, for the
cost thereof.

            (b) If Lessee fails to perform Lessee's obligations under this
paragraph 7.2 or under any other paragraph of this Lease, Lessor may enter upon
the Premises after ten (10) days' prior written notice to Lessee (except in the
case of emergency, in which no notice shall be required), perform such
obligations on Lessee's behalf and put the Premises in good order, condition and
repair, and the cost thereof together with interest thereon at the maximum rate
then allowable by law shall be due and payable as additional rent to Lessor
together with Lessee's next Base Rent installment.

            (c) On the last day of the term hereof, or on any sooner
termination, Lessee shall surrender the Premises to Lessor in the same condition
as received, ordinary wear and tear excepted, clean and free of debris. Any
damage or deterioration of the Premises shall not be deemed ordinary wear and
tear if the same could have been prevented by good maintenance practices. Lessee
shall repair any damage to the Premises occasioned by the installation or
removal of Lessee's trade fixtures, alterations, furnishings and equipment.
Notwithstanding anything to the contrary otherwise stated in this Lease, Lessee
shall leave the air lines, power panels, electrical distribution systems,
lighting fixtures, ???

      7.3 ALTERATIONS AND ADDITIONS.

            (a) Lessee shall not, without Lessor's prior written consent make
any alterations, improvements, additions, or Utility Installations in, on or
about the Premises, or the Industrial Center. Lessee shall make no change or
alteration to the exterior of the Premises nor the exterior of the Building nor
the Industrial Center without Lessor's prior written consent. As used in this
paragraph 7.3 the term "Utility Installation" shall mean carpeting, window
coverings, air lines, power panels, electrical distribution systems, lighting
fixtures, space heaters, air conditioning, plumbing, and fencing. Lessor may
require that Lessee remove any or all of said alterations, improvements,
additions or Utility Installations at the

                                      -2-
<PAGE>   9
expiration of the term, and restore the Premises and the Industrial Center to
their prior condition. Lessor may require Lessee to provide Lessor, at Lessee's
sole cost and expense, a lien and completion bond in an amount equal to one and
one-half times the estimated cost of such improvements, to insure Lessor
against any liability for mechanic's and materialmen's liens and to insure
completion of the work. Should Lessee make any alterations, improvements,
additions or Utility installations without the prior approval of Lessor, Lessor
may, at any time during the term of this Lease, require that Lessee remove any
or all of the same.

          (b)  Any alterations, improvements, additions or Utility installations
in or about the Premises or the Industrial Center that Lessee shall desire to
make and which requires the consent of the Lessor shall be presented to Lessor
in written form, with proposed detailed plans. If Lessor shall give its consent,
the consent shall be deemed conditioned upon Lessee acquiring a permit to do so
from appropriate governmental agencies, the furnishing of a copy thereof to
Lessor prior to the commencement of the work and the compliance by Lessee of all
conditions of said permit in a prompt and expeditious manner.

          (c)  Lessee shall pay, when due, all claims for labor or materials
furnished or alleged to have been furnished to or for Lessee at or for use in
the Premises, which claims are or may be secured by any mechanic's or
materialmen's lien against the Premises, or the Industrial Center, or any
interest therein. Lessee shall give lessor not less than ten (10) days' notice
prior to the commencement of any work in the Premises, and Lessor shall have the
right to post notices of non-responsibility in or on the Premises or the
Building as provided by law. If Lessee shall, in good faith, contest the
validity of any such lien, claim or demand, then Lessee shall, at its sole
expense defend itself and Lessor against the same and shall pay and satisfy any
such adverse judgment that may be rendered thereon before the enforcement
thereof against the Lessor or the Premises or the Industrial Center, upon the
condition that if Lessor shall require, Lessee shall furnish to Lessor a surety
bond satisfactory to Lessor in an amount equal to such contested lien claim or
demand indemnifying Lessor against liability for the same and holding the
Premises and the Industrial Center free from the effect of such lien or claim.
In addition, Lessor may require Lessee to pay Lessor's attorney's fees and costs
in participating in such action if Lessor shall decide it is to Lessor's best
interest to do so.

          (d)  All alterations, improvements, additions and Utility
Installations (whether or not such Utility Installations constitute trade
fixtures of Lessee), which may be made on the Premises, shall be the property of
Lessor and shall remain upon and be surrendered with the Premises at the
expiration of the Lease term, unless Lessor requires their removal pursuant to
paragraph 7.3(a). Notwithstanding the provisions of this paragraph 7.3(d),
Lessee's machinery and equipment, other than that which is affixed to the
Premises so that it cannot be removed without material damage to the Premises,
and other than Utility Installations, shall remain the property of Lessee and
may be removed by Lessee subject to the provisions of paragraph 7.2.

     7.4  UTILITY ADDITIONS. Lessor reserves the right to install new or
additional utility facilities throughout the Building and the Common Areas for
the benefit of Lessor or Lessee, or any other lessee of the Industrial Center,
including, but not by way of limitation, such utilities as plumbing, electrical
systems, security systems, communication systems, and fire protection and
detection systems, so long as such installations do not unreasonably interfere
with Lessee's use of the premises.

B.   INSURANCE; INDEMNITY.

     8.1  LIABILITY INSURANCE -- LESSEE. Lessee shall, at Lessee's expense,
obtain and keep in force during the term of this Lease a policy of Combined
Single Limit Bodily Injury and Property Damage Insurance insuring Lessee and
Lessor against any liability arising out of the use, occupancy or maintenance
of the Premises and the Industrial center. Such insurance shall be in an amount
not less than $500,000.00 per occurrence. The policy shall insure performance
by Lessee of the indemnity provisions of this Paragraph 8. The limits of said
insurance shall not, however, limit the liability of Lessee hereunder.

     8.2  LIABILITY INSURANCE -- LESSOR. Lessor shall obtain and keep in force
during the term of this Lease a policy of Combined Single Limit Bodily Injury
and Property Damage Insurance insuring Lessor, but not Lessee, against any
liability arising out of the ownership, use, occupancy or maintenance of the
Industrial Center in an amount not less than $500,000.00 per occurrence.

     8.3  PROPERTY INSURANCE. Lessor shall obtain and keep in force during the
term of this Lease a policy or policies of insurance covering loss or damage to
the Industrial Center Improvements, but not Lessee's personal property,
fixtures, equipment or tenant improvements, in an amount not to exceed the full
replacement value thereof, as the same may exist from time to time, providing
protection against all perils included within the classification of fire,
extended coverage, vandalism, malicious mischief, flood (in the event same is
required by a lender having a lien on the Premises), special extended perils
("all risk," as such term is used in the insurance industry), plate glass
insurance and such other insurance as Lessor deems advisable. In addition,
Lessor shall obtain and keep in force, during the term of this Lease, a policy
of rental value insurance covering a period of one year, with loss payable to
Lessor, which insurance shall also cover all Operating Expenses for said period.

     8.4  PAYMENT OF PREMIUM INCREASE.

          (a)  After the term of this Lease has commenced, Lessee shall not be
responsible for paying Lessee's Share of any increase in the property insurance
premium for he Industrial Center specified by Lessor's insurance carrier as
being caused by the use, acts or omissions of any other lessee of the
Industrial Center, or by the nature of such other lessee's occupancy which
create an extraordinary or unusual risk.

          (b)  Lessee, however, shall pay the entirety of any increase in the
property insurance premium for the Industrial Center over what it was
immediately prior to the commencement of the term of this Lease if the increase
is specified by Lessor's Insurance carrier as being caused by the nature of
Lessee's occupancy or any act or omission of Lessee.

          (c)  Lessee shall pay to Lessor, during the term hereof, in addition
to the rent, Lessee's Share (as defined in paragraph 4.2[a]) of the amount of
any increase in premiums for the insurance required under paragraphs 8.2 and 8.3
over and above such premiums paid during the Base Period, as hereinafter
defined, whether such premium increase shall be the result of the nature of
Lessee's occupancy, any act or omission of Lessee, requirements of the holder of
a mortgage or deed of trust covering the Premises, increased valuation of the
Premises, or general rate increases. In the event that the Premises have been
occupied previously, the words "Base Period" shall mean the last twelve months
of the prior occupancy. In the event that the Premises have never been occupied
previously, the premiums during the "Base Period" shall be deemed to be the
lowest premiums reasonably obtainable for said insurance assuming the most
nominal use of the Premises. Provided, however, in lieu of the Base Period, the
parties may insert a dollar amount at the end of this sentence which figure
shall be considered as the insurance premium for the Base Period: $1,098.23. In
no event, however, shall Lessee be responsible for any portion of the premium
cost attributable to liability insurance coverage in excess of $500,000
procured under paragraph 8.2.

          (d) Lessee shall pay any such premium increases to Lessor within 30
days after receipt by Lessee of a copy of the premium statement or other
satisfactory evidence of the amount due. If the insurance policies maintained
hereunder cover other improvements in addition to the Premises, Lessor shall
also deliver to Lessee a statement of the amount of such increase attributable
to the Premises and showing in reasonable detail, the manner in which such
amount was computed. If the term of this Lease shall not expire concurrently
with the expiration of the period covered by such insurance, Lessee's liability
for premium increases shall be prorated on an annual basis.

     8.5  INSURANCE POLICIES. Insurance required hereunder shall be in companies
holding a "General Policyholders Rating" of at least B plus, or such other
rating as may be required by a lender having a lien on the Premises, 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
carried by Lessor. Lessee shall deliver to Lessor copies of the liability
insurance policies required under paragraph 8.1 or certificates evidencing the
existence and amounts of such insurance within seven (7) days after the
commencement date of this Lease. No such policy shall be cancellable or subject
to reduction of coverage or other modification except after thirty (30) days
prior written notice to Lessor. Lessee shall, at least thirty (30) days prior
to the expiration of such policies, furnish Lessor with renewals or "binders"
thereof.

     8.6  WAIVER OF SUBROGATION. Lessee and Lessor each hereby release and
relieve the other, and waive their entire right of recovery against the other
for loss or damage arising out of or incident to the perils insured against
which perils occur in, on or about the Premises, whether due to the negligence
of Lessor or Lessee or their agents, employees, contractors and/or invitees.
Lessee and Lessor shall, upon obtaining the policies of insurance required
hereunder, give notice to the insurance carrier or carriers that the foregoing
mutual waiver of subrogation is contained in this Lease.

     8.7. INDEMNITY. Except for the negligent acts of the Lessor or Lessor's
agents, employees, contractors, customers or invitees, Lessee shall indemnify
and hold harmless Lessor from and against any and all claims arising from
Lessee's use of the Industrial Center, or from the conduct of Lessee's business
or from any activity, work or things done, permitted or suffered by Lessee in
or about the Premises or elsewhere and shall further indemnify and hold harmless
Lessor from and against any and all claims arising from any breach or default in
the performance of any obligation on Lessee's part to be performed under the
terms of this Lease, or arising from any act or omission of Lessee, or any of
Lessee's agents, contractors, or employees, and from and against all costs,
attorney's fees, expenses and liabilities incurred in the defense of any such
claim or any action or proceeding brought thereon, and in case any action or
proceeding be brought against Lessor by reason of any such claim, Lessor shall
cooperate with Lessee in such defense. Lessee, as a material part of the
consideration to Lessor, hereby assumes all risk of damage to property of Lessee
or injury to persons, in, upon or about the Industrial Center arising from any
cause and Lessee hereby waives all claims in respect thereof against Lessor.

     8.8  EXEMPTION OF LESSOR FORM LIABILITY. Except for the negligent acts of
the Lessor or Lessor's agents, employees, contractors, customers or invitees,
Lessee hereby agrees that Lessor shall not be liable for injury to Lessee's
business or any loss of income therefrom or for damage to the goods, wares,
merchandise or other property of Lessee, Lessee's employees, invitees,
customers, or any other person in or about the Premises or the Industrial
Center, nor shall Lessor be liable for injury to the person of Lessee, Lessee's
employees, agents or contractors, whether such damage or injury is caused by or
results from fire, steam, electricity, gas, water or rain, or from the breakage,
leakage, obstruction or other defects of pipes, sprinklers, wires, appliances,
plumbing, air conditioning or lighting fixtures, or from any other cause,
whether said damage or injury results form conditions arising upon the Premises
or upon other portions of the Industrial Center, or from other sources or places
and regardless of whether the cause of such damage or injury or the means of
repairing the same is inaccessible to Lessee. Lessor shall not be liable for any
damages arising from any act or neglect of any other lessee, occupant or user of
the Industrial Center, nor from the failure of Lessor to enforce the provisions
of any other lease of the Industrial Center, except for the negligent acts of
the Lessor or Lessor's agents, employees, contractors, customers or invitees.

          (b)  Uninsured Loss: Subject to the provisions of paragraphs 9.4 and
9.5, if at any time during the term of this Lease there is damage which is not
an Insured Loss and which falls within the classification of Premises Partial

willful act of Lessee (in which event Lessee shall make the repairs at Lessee's
expense), which damage prevents Lessee from using the Premises, Lessor may at
lessor's option either (i) repair such damage as soon as reasonably possible at
Lessor's expense, in which event this Lease shall continue in full force and
effect, or (ii) give written notice to Lessee within thirty (30) days after the

          (b)  Notwithstanding paragraph 9.4(a), in the even that Lessee has an
option to extend or renew this Lease, and the time within which said option may
be exercised has not yet expired, Lessee shall exercise such option, if it is

          (a)  In the event lessor repairs or restores the Premises pursuant to
the provisions of this paragraph 9, the rent payable hereunder for the period

proportion to the degree to which Lessee's use of the Premises is impaired.

restoration within ninety (90) days after such obligation shall accrue, Lessee
may at Lessee's option cancel and terminate this Lease by giving Lessor written

10.  REAL PROPERTY TAXES.

     10.1 PAYMENT OF TAX INCREASE. Lessor shall pay the real property tax, as
defined in paragraph 10.3, applicable to the Industrial Center, provided,
however, that Lessee shall pay, in addition to rent, Lessee's Share (as defined
in paragraph 4.2[a]) of the amount, if any, by which real property taxes
applicable to the Premises increase over the fiscal real estate tax year 1993
- - 1994. Such payment shall be made by Lessee within thirty (30) days after
receipt of lessor's written statement setting forth the amount of such increase
and the computation thereof. If the term of this Lease shall not expire
concurrently with the expiration of the tax fiscal year, Lessee's liability for
increased taxes for the last partial lease year shall be prorated on an annual
basis.

     10.2 ADDITIONAL IMPROVEMENTS. Lessee shall not be responsible for paying
Lessee's Share of any increase in real property tax 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. Lessee shall, however, pay to Lessor
at the time that Operating Expenses are payable under paragraph 4.2(c) the
entirety of any increase in real property tax if assessed solely by reason of
additional improvements placed upon the Premises by Lessee or at Lessee's
request.

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

     10.4 JOINT ASSESSMENT. If the Industrial Center is not separately
assessed, Lessee's Share of the real property tax liability 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 PERSONAL PROPERTY TAXES.

          (a)  Lessee shall pay prior to delinquency all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Lessee contained in the Premises or elsewhere. When possible,
Lessee shall cause said trade fixtures, furnishings, equipment and all other
personal property to be assessed and billed separately from the real property
of Lessor.

          (b)  If any of lessee's said personal property shall be assessed with
Lessor's real property, Lessee shall pay to Lessor the taxes attributable to
Lessee within ten (10) days after receipt of a written statement setting forth
the taxes applicable to Lessee's property.

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

12.  ASSIGNMENT AND SUBLETTING

     12.1 LESSOR'S CONSENT REQUIRED. Lessee shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in the Lease or in the Premises,
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold. Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer, mortgage, encumbrance or
subletting without such consent shall be void, and shall constitute a breach of
this Lease without the need for notice to Lessee under paragraph 13.1.

     12.2 LESSEE AFFILIATE. Notwithstanding the provisions of paragraph 12.1
hereof. Lessee may assign or sublet the Premises, or any portion thereof,
without Lessor's consent, to any corporation which controls, is controlled by
or is under common control of Lessee, or to any corporation resulting from the
merger or consolidation with Lessee, or to any person or entity which acquires
all the assets of Lessee as a going concern of the business that is being
conducted on the Premises, all of which are referred to as "Lessee Affiliate,"
provided that before such assignment shall be effective said assignee shall
assume, in full, the obligations of Lessee under this Lease.

     12.3 TERMS AND CONDITIONS OF ASSIGNMENT. Regardless of Lessor's consent, no
assignment shall release Lessee of Lessee's obligations hereunder or alter the
primary liability of Lessee to pay the Base Rent and Lessee's Share of Operating
Expenses, and to perform all other obligations to be performed by Lessee
hereunder. Lessor may accept rent from any person other than Lessee pending
approval or disapproval of such assignment. Neither a delay in the approval or
disapproval of such assignment nor the acceptance of rent shall constitute a
waiver or estoppel of Lessor's right to exercise its remedies for the breach of
any of the terms or conditions of this paragraph 12 or this Lease. Consent to
one assignment shall not be deemed consent to any subsequent assignment. In the
event of default by any assignee of Lessee or any successor of Lessee, in the
performance of any of the terms hereof, Lessor may proceed directly against
Lessee without the necessity of exhausting remedies against said assignee.
Lessor may consent to subsequent assignments of this Lease or amendments or
modifications to this Lease with assignees of Lessee, without notifying Lessee,
or any successor of Lessee, and without obtaining its or their consent thereto
and such action shall not relieve Lessee of liability under this Lease.

     12.4 TERMS AND CONDITIONS APPLICABLE TO SUBLETTING. Regardless of Lessor's
consent, the following terms and conditions shall apply to any subletting by
Lessee of all or any part of the Premises and shall be included in subleases:

          (a) Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease heretofore or
hereafter made by Lessee, and Lessor may collect such rent and income and apply
same toward Lessee's obligations under this Lease; provided, however, that until
a default shall occur in the performance of Lessee's obligations under this
Lease; Lessee may receive, collect and enjoy the rents accruing under such
sublease. Lessor shall not, by reason of this or any other assignment of such
sublease to Lessor nor by reason of the collection of the rents from a
sublessee, be deemed liable to the sublessee for any failure of Lessee to
perform and comply with any of Lessee's obligations to such sublessee under such
sublease. Lessee hereby irrevocably authorizes and directs any such sublessee,
upon receipt of a written notice from Lessor stating that a default exists in
the performance of Lessee's obligations under this Lease, to pay to Lessor the
rents due and to become due under the sublease. Lessee agrees that such
sublessee shall have the right to rely upon any such statement and request from
Lessor, and that such sublessee shall pay such rents to Lessor without any
obligation or right to inquire as to whether such default exists and
notwithstanding any notice from or claim from Lessee to the contrary. Lessee
shall have no right or claim against such sublessee or Lessor for any such rents
so paid by said sublessee to Lessor.

          (b) No sublease entered into by Lessee shall be effective unless and
until it has been approved in writing by Lessor. In entering into any sublease,
Lessee shall use only such form of sublease as is satisfactory to Lessor, and
once approved by Lessor, such sublease shall not be changed or modified without
Lessor's prior written consent. Any sublessee shall, by reason of entering into
a sublease under this Lease, be deemed, for the benefit of Lessor, to have
assumed and agreed to conform and comply with each and every obligation herein
to be performed by Lessee other than such obligations as are contrary to or
inconsistent with provisions contained in a sublease to which Lessor has
expressly consented in writing.

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

          (d) The consent by Lessor to any subletting shall not release Lessee
from its obligations or alter the primary liability of Lessee to pay the rent
and perform and comply with all of the obligations of Lessee to be performed
under this Lease.

          (e) The consent by Lessor to any subletting shall not constitute a
consent to any subsequent subletting by Lessee or to any assignment or
subletting by the sublessee. However, Lessor may consent to subsequent
sublettings and assignments of the sublease or any amendments or modifications
thereto without notifying Lessee or anyone else liable on the Lease or sublease
and without obtaining their consent and such action shall not relieve such
persons from liability.

          (f) In the event of any default under this Lease, Lessor may proceed
directly against Lessee any guarantors or any one else responsible for the
performance of this Lease, including the sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible therefor to
Lessor, or any security held by Lessor or Lessee.

          (g) In the event Lessee shall default in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of Lessee under such sublease from the time of
the exercise of said option to the termination of such sublease; provided,
however, Lessor shall not be liable for any prepaid rents or security deposit
paid by such sublessee to Lessee or for any other prior defaults of Lessee under
such sublease.

          (h) Each and every consent required of Lessee under a sublease shall
also require the consent of Lessor.

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

          (j) Lessor's written consent to any subletting of the Premises by
Lessee shall not constitute an acknowledgement that no default then exists
under this Lease of the obligations to be performed by Lessee nor shall such
consent be deemed a waiver of any then existing default, except as may be
otherwise stated by Lessor at the time.

          (k) With respect to any subletting to which Lessor has consented,
Lessor agrees to deliver a copy of any notice of default by Lessee to the
sublessee. Such sublessee shall have the right to cure a default of Lessee
within ten (10) days after service of said notice of default upon such
sublessee, and the sublessee shall have a right of reimbursement and offset
from and against Lessee for any such defaults cured by the sublessee.

     12.5 ATTORNEY'S FEES. In the event Lessee shall assign or sublet the
premises or request the consent of Lessor to any assignment or subletting or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable attorney's fees incurred in
connection therewith, such attorney's fees not to exceed $200.00 for each such
request.

13.  DEFAULT; REMEDIES.

     13.1 DEFAULT. The occurrence of any one or more of the following events
shall constitute a material default of this Lease by Lessee:

     (a) The vacating or abandonment of the Premises by Lessee.

     (b) The failure by Lessee to make any payment of rent or any other payment
required to be made by Lessee hereunder, as and when due, where such failure
shall continue for a period of three (3) days after written notice thereof from
Lessor to Lessee. In the event that Lessor serves Lessee with a Notice to Pay
Rent or Quit pursuant to applicable Unlawful Detainer statutes such Notice to
Pay Rent or Quit shall also constitute the notice required by this subparagraph.

     (c) Except as otherwise provided in this Lease, the failure by Lessee to
observe or perform any of the covenants, conditions or provisions of this Lease
to be observed or performed by Lessee, other than described in paragraph (b)
above, where such failure shall continue for a period of thirty (30) days after
written notice thereof from Lessor to Lessee; provided, however, that if the
nature of Lessee's noncompliance is such that more than thirty (30) days are
reasonably required for its cure, then Lessee shall not be deemed to be in
default if Lessee commenced such cure within said thirty (30) day period and
thereafter diligently prosecutes such cure to completion. To the extent
permitted by law, such thirty (30) day notice shall constitute the sole and
exclusive notice required to be given to Lessee under applicable Unlawful
Detainer statutes.

     (d) (i) The making by Lessee of any general arrangement or general
assignment for the benefit of creditors; (ii) Lessee becomes a "debtor" as
defined in 11 U.S.C. Section 101 or any successor statute thereto (unless, in
the case of a petition filed against Lessee, the same is dismissed within sixty
(60) days); (iii) the appointment of a trustee or receiver to take possession of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where possession is not restored to Lessee within thirty
(30) days; or (iv) the attachment, execution or other judicial seizure of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where such seizure is not discharged within thirty (30)
days. In the event that any provision of this paragraph 13.1(d) is contrary to
any applicable law, such provision shall be of no force or effect.

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

     13.2 REMEDIES. In the event of any such material default by Lessee, Lessor
may at any time thereafter, with or without notice or demand and without
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such default:

     (a) Terminate Lessee's right to possession of the premises by any lawful
means, in which case this Lease and the term hereof shall terminate and Lessee
shall immediately surrender possession of the Premises to Lessor. In such event
Lessor shall be entitled to recover from Lessee all damages incurred by Lessor
by reason of Lessee's default including, but not limited to, the cost of
recovering possession of the premises, expenses of reletting, including
necessary renovation and alteration of the premises, reasonable attorney's
fees, and any real estate commission actually paid; the worth at the time of
award by the court have jurisdiction thereof of the amount by which the unpaid
rent for the balance of the term after the time of such award exceeds the
amount of such rental loss for the same period that Lessee proves could be
reasonably avoided; that portion of the leasing commission paid by Lessor
pursuant to paragraph 15 applicable to the unexpired term of this Lease.


                                      -5-
<PAGE>   12
          (b)   Maintain Lessee's right to possession in which case this Lease
shall continue in effect whether or not Lessee shall have vacated or abandoned
the Premises. In such event Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease,including the right to recover the rent as
it becomes due hereunder.

          (c)   Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located. Unpaid installments of rent and other unpaid monetary obligations of
Lessee under the terms of this Lease shall bear interest from the date due at
the maximum rate then allowable by law.

     13.3  DEFAULT BY LESSOR. Lessor shall not be in default unless Lessor fails
to perform obligations required of Lessor within a reasonable time, but in no
event later than thirty (30) days after written notice by Lessee to Lessor and
to the holder of any first mortgage or deed of trust covering the Premises whose
name and address shall have theretofore been furnished to Lessee in writing,
specifying wherein Lessor has failed to perform such obligation; provided,
however, that if the nature of Lessor's obligation is such that more than thirty
(30) days are required for performance then Lessor shall not be in default if
Lessor commences performance within such thirty (30) day period and thereafter
diligently prosecutes the same to completion.

     13.4  LATE CHARGES. Lessee hereby acknowledges that late payment by Lessee
to Lessor of Base Rent, Lessee's Share of Operating Expenses or other sums due
hereunder will cause Lessor to incur costs not contemplated by this Lease, the
exact amount of which will be extremely difficult to ascertain. Such costs
include, but are not limited to, processing and accounting charges, and late
charges which may be imposed on Lessor by the terms of any mortgage or trust
deed covering the Industrial Center. Accordingly, if any installment of Base
Rent, Operating Expenses, or any other sum due from Lessee shall not be received
by Lessor or Lessor's designee within ten (10) days after such amount shall be
due, then, without any requirement for notice to Lessee, Lessee shall pay to
Lessor a late charge equal to 6% of such overdue amount. The parties hereby
agree that such late charge represents a fair and reasonable estimate of the
costs Lessor will incur by reason of late payment by Lessee. Acceptance of such
late charge by Lessor shall in no event constitute a waiver of Lessee's default
with respect to such overdue amount, nor prevent Lessor from exercising any of
the other rights and remedies granted hereunder. In the event that a late charge
is payable hereunder, whether or not collected, for three (3) consecutive
installments of any of the aforesaid monetary obligations of Lessee, then Base
Rent shall automatically become due and payable quarterly in advance, rather
than monthly, notwithstanding paragraph 4.1 or any other provision of this Lease
to the contrary.

14.   CONDEMNATION. If the Premises or any portion thereof or the Industrial
Center are taken under the power of eminent domain or sold under the threat of
the exercise of said power (all of which are herein called "condemnation"), this
Lease shall terminate as to the part so taken as of the date the condemning
authority takes title or possession, whichever first occurs. If more than ten
percent of the floor area of the Premises, or more than twenty-five percent of
that portion of the Common Areas designated as parking for the Industrial Center
is taken by condemnation, Lessee may, at Lessee's option, to be exercised in
writing only within ten (10) days after Lessor shall have given Lessee written
notice of such taking (or in the absence of such notice, within ten (10) days
after the condemning authority shall have taken possession) terminate this Lease
as of the date the condemning authority takes such possession. If Lessee does
not terminate this Lease in accordance with the foregoing, this Lease shall
remain in full force and effect as to the portion of the Premises remaining,
except that the rent shall be reduced in the proportion that the floor area of
the Premises taken bears to the total floor area of the Premises. No reduction
of rent shall occur if the only area taken is that which does not have the
Premises located thereon. Any award for the taking of all or any part of the
Premises under the power of eminent domain or any payment made under threat of
the exercise of such power shall be the property of Lessor, whether such award
shall be made as compensation for diminution in value of the leasehold or for
the taking of the fee, or as severance damages; provided, however, that Lessee
shall be entitled to any award for loss of or damage to Lessee's trade fixtures
and removable personal property. In the event that this Lease is not terminated
by reason of such condemnation, Lessor shall to the extent of severance damages
received by Lessor in connection with such condemnation, repair any damage to
the Premises caused by such condemnation except to the extent that Lessee has
been reimbursed therefor by the condemning authority. Lessee shall pay any
amount in excess of such severance damages required to complete such repair.

15.   BROKER'S FEE.

     (a)   Upon execution of this Lease by both parties, Lessor shall pay to
NONE Licensed real estate broker(s), a fee as set forth in a separate agreement
between Lessor and said broker(s), or in the event there is no separate
agreement between Lessor and said broker(s), the sum of $-0-, for brokerage
services rendered by said broker(s) to Lessor in this transaction.

     (b)   Lessor further agrees that if Lessee exercises any Option, as defined
in paragraph 39.1 of this Lease, which is granted to Lessee under this Lease, or
any subsequently granted option which is substantially similar to an Option
granted to Lessee under this Lease, or if Lessee acquires any rights to the
Premises or other premises described in this Lease which are substantially
similar to what Lessee would have acquired had an Option herein granted to
Lessee been exercised, or if Lessee remains in possession of the Premises after
the expiration of the term of this Lease after having failed to exercise an
Option, or if said broker(s) are the procuring cause of any other lease or sale
entered into between the parties pertaining to the Premises and/or any adjacent
property in which Lessor has an interest, then as to any of said transactions.
Lessor shall pay said broker(s) a fee in accordance with the schedule of said
broker(s) in effect at the time of execution of this Lease.

     (c)   Lessor agrees to pay said fee not only on behalf of Lessor but also
on behalf of any person, corporation, association, or other entity having an
ownership interest in said real property or any part thereof, when such fee is
due hereunder. Any transferee of Lessor's interests in this Lease, whether such
transfer is by agreement or by operations of law, shall be deemed to have
assumed Lessor's obligation under this paragraph 15. Said broker shall be a
third party beneficiary of the provisions of this paragraph 15.

16.   ESTOPPEL CERTIFICATE.

     (a)   Each party (as "responding party") shall at any time upon not less
than ten (10) days' prior written notice from the other party ("requesting
party") execute, acknowledge and deliver to the requesting party a statement
in writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease, as so modified, is in full force and effect) and the date to
which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to the responding party's knowledge, any
uncured defaults on the part of the requesting party, or specifying such
defaults if any are claimed. Any such statement may be conclusively relied upon
by any prospective purchaser or encumbrancer of the Premises or of the business
of the requesting party.

     (b)   At the requesting party's option, the failure to deliver such
statement within such time shall be a material default of this Lease by the
party who is to respond, without any further notice to such party, or it shall
be conclusive upon such party that (i) this Lease is in full force and effect,
without modification except as may be represented by the requesting party, (ii)
there are no uncured defaults in the requesting party's performance, and (iii)
if Lessor is the requesting party, not more than one month's rent has been paid
in advance.

     (c)   If Lessor desires to finance, refinance, or sell the Industrial
Center, or any part thereof, Lessee hereby agrees to deliver to any lender or
purchaser designated by Lessor such financial statements of Lessee as may be
reasonably required by such lender or purchaser. Such statements shall include
the past three (3) year's financial statements of Lessee. All such financial
statements shall be received by Lessor and such lender or purchaser in
confidence and shall be used only for the purposes herein set forth.

17.   LESSOR'S LIABILITY. The term "Lessor" as used herein shall mean only the
owner or owners, at the time in question, of the fee title or a lessee's
interest in a ground lease of the Industrial Center, and except as expressly
provided in paragraph 15, in the event of any transfer of such title or interest
Lessor herein named (and in case of any subsequent transfers then the grantor)
shall be relieved from and after the date of such transfer of all liability as
respects Lessor's obligations thereafter to be performed, provided that any
funds in the hands of Lessor or the then grantor at the time of such transfer,
in which Lessee has an interest, shall be delivered to the grantee. The
obligations contained in this Lease to be performed by Lessor shall, subject as
aforesaid, be binding on Lessor's successors and assigns, only during their
respective periods of ownership.

18.   SEVERABILITY. The invalidity of any provision of this Lease as determined
by a court of competent jurisdiction, shall in no way affect the validity of
any other provision thereof.

19.   INTEREST ON PAST-DUE OBLIGATIONS. Except as expressly herein provided, any
amount due to Lessor not paid when due shall bear interest at the maximum rate
then allowable by law from the date due. Payment of such interest shall not
excuse or cure any default by Lessee under this Lease; provided, however, that
interest shall not be payable on late charges incurred by Lessee nor on any
amounts upon which late charges are paid by Lessee.

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

21.   ADDITIONAL RENT. All monetary obligations of Lessee to Lessor under the
terms of this Lease, including but not limited to Lessee's Share of Operating
Expenses and Insurance and tax expenses payable shall be deemed to be rent.

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

23.   NOTICES. Any notice required or permitted to be given hereunder shall be
in writing and may be given by personal delivery or by certified mail, and if
given personally or by mail, shall be deemed sufficiently given if addressed to
Lessee or to Lessor at the address noted below the signature of the respective
parties, as the case may be. Either party may by notice to the other specify a
different address for notice purposes except that upon Lessee's taking
possession of the Premises, the Premises shall constitute Lessee's address for
notice purposes. A copy of all notices required or permitted to be given to
Lessor hereunder shall be concurrently transmitted to such party or parties at
such addresses as Lessor may from time to time hereafter designate by notice to
Lessee.

                                      -6-

<PAGE>   13
24.  WAIVERS  No waiver by Lessor or any provision hereof shall be deemed a
waiver of any other provision hereof or of any subsequent breach by Lessee of
the same or any other provision. Lessor's consent to, or approval of, any act
shall not be deemed to render unnecessary the obtaining of Lessor's consent to
or approval of any subsequent act by Lessee. The acceptance of rent hereunder by
Lessor shall not be a waiver of any preceding breach by Lessee of any provision
hereof, other than the failure of Lessee to pay the particular rent so accepted,
regardless of Lessor's knowledge of such preceding breach at the time of
acceptance of such rent.

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

26.  HOLDING OVER.  If Lessee, with Lessor's consent, remains in possession of
the Premises or any part thereof after the expiration of the term hereof, such
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease pertaining to the obligations of Lessee, but all Options, if any, granted
under the terms of this Lease shall be deemed terminated and be of no further
effect during said month to month tenancy with a ninety (90) day written notice
of intent to vacate premises.

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

28.  COVENANTS AND CONDITIONS.  Each provision of this Lease performable by
Lessee shall be deemed both a covenant and a condition.

29.  BINDING EFFECT; CHOICE OF LAW.  Subject to any provisions hereof
restricting assignment or subletting by Lessee and subject to the provisions of
paragraph 17, this Lease shall bind the parties, their personal representatives,
successors and assigns. This Lease shall be governed by the laws of the State
where the Industrial Center is located and any litigation concerning this Lease
between the parties hereto shall be initiated in the county in which the
Industrial Center is located.

30.  SUBORDINATION.

     (a)  This Lease, and any Option granted hereby, at Lessor's option, shall
be subordinate to any ground lease, mortgage, deed of trust, or any other
hypothecation or security now or hereafter placed upon the Industrial Center and
to any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.
Notwithstanding such subordination, Lessee's right to quiet possession of the
Premises shall not be disturbed if Lessee is not in default and so long as
Lessee shall pay the rent and observe and perform all of the provisions of this
Lease, unless this Lease is otherwise terminated pursuant to its terms. If any
mortgagee, trustee or ground lessor shall elect to have this Lease and any
Options granted hereby prior to the lien of its mortgage, deed of trust or
ground lease, and shall give written notice thereof to Lessee, this Lease and
such Options shall be deemed prior to such mortgage, deed of trust or ground
lease, whether this Lease or such Options are dated prior or subsequent to the
date of said mortgage, deed of trust or ground lease or the date of recording
thereof.

     (b)  Lessee agrees to execute any documents required to effectuate an
attornment, a subordination or make this Lease or any Option granted herein
prior to the lien of any mortgage, deed of trust or ground lease, as the case
may be. Lessee's failure to execute such documents within ten (10) days after
written demand shall constitute a material default by Lessee hereunder without
further notice to Lessee or, at Lessor's option, Lessor shall execute such
documents on behalf of Lessee as Lessee's attorney-in-fact. Lessee does hereby
make, constitute and irrevocably appoint Lessor as Lessee's attorney-in-fact and
in Lessee's name, place and stead, to execute such documents in accordance with
this paragraph 30(b).

31.  ATTORNEY'S FEES.  If either party or the broker(s) named herein bring an
action to enforce the terms hereof or declare rights hereunder, the prevailing
party in any such action, on trial or appeal, shall be entitled to his
reasonable attorney's fees to be paid by the losing party as fixed by the court.
The provisions of this paragraph shall inure to the benefit of the broker named
herein who seeks to enforce a right hereunder.

32.  LESSOR'S ACCESS.  Lessor and Lessor's agents shall have the right to enter
the Premises at reasonable times for the purpose of inspecting the same, showing
the same to prospective purchasers, lenders, or lessees, and making such
alterations, repairs, improvements or additions to the Premises or to the
Industrial Center as Lessor may deem necessary or desirable. Lessor may at any
time place on or about the Premises or the Building any ordinary "For Sale"
signs and Lessor may at any time during the last 120 days of the term hereof
place on or about the Premises any ordinary "For Lease" signs. All activities of
Lessor pursuant to this paragraph shall be without abatement of rent, nor shall
Lessor have any liability to Lessee for the same.

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

34.  SIGNS.  Lessee shall not place any sign upon the Premises or the Industrial
Center without Lessor's prior written consent. Under no circumstances shall
Lessee place a sign on any roof of the Industrial Center.

35.  MERGER.  The voluntary or other surrender of this Lease by Lessee, or a
mutual cancellation thereof, or a termination by Lessor, shall not work a
merger, and shall, at the option of the Lessor, terminate all or any existing
subtenancies or may, at the option of the Lessor, operate as an assignment to
Lessor of any or all of such subtenancies.

36.  CONSENTS.  Except for paragraph 33 hereof, wherever in this Lease the
consent of one party is required to an act of the other party such consent shall
not be unreasonably withheld or delayed.

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

38.  QUIET POSSESSION.  Upon Lessee paying the rent for the Premises and
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease. The individuals executing this Lease on behalf of
Lessor represent and warrant to Lessee that they are fully authorized and
legally capable of executing this Lease on behalf of Lessor and that such
execution is binding upon all parties holding an ownership interest in the
Industrial Center.

39.  OPTIONS.

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

     39.2  OPTIONS PERSONAL. Each Option granted to Lessee in this Lease is
personal to the original Lessee and may be exercised only by the original Lessee
while occupying the Premises who does so without the intent of thereafter
assigning this Lease or subletting the Premises or any portion thereof,and may
not be exercised or be assigned, voluntarily or involuntarily, by or to any
person or entity other than Lessee, provided, however, that an Option may be
exercised by or assigned to any Lessee Affiliate as defined in paragraph 12.2 of
this Lease. The Options, if any, herein granted to Lessee are not assignable
separate and apart from this Lease, nor may any Option be separated from this
Lease in any manner, either by reservation or otherwise.

     39.3  MULTIPLE OPTIONS.  In the event that Lessee has any multiple options
to extend or renew this Lease a later option cannot be exercised unless the
prior option to extend or renew this Lease has been so exercised.

     39.4  EFFECT OF DEFAULT ON OPTIONS

           (a) Lessee shall have no right to exercise an Option, notwithstanding
any provision in the grant of Option to the contrary, (i) during the time
commencing from the date Lessor gives to Lessee a notice of default pursuant to
paragraph 13.1(b) or 13.1(c) and continuing until the noncompliance alleged in
said notice of default is cured, or (ii) during the period of time commencing on
the date after a monetary obligation to Lessor is due from Lessee and unpaid
(without any necessity for notice thereof to Lessee) and continuing until the
obligation is paid, or (iii) at any time after an event of default described in
paragraphs 13.1(a), 13.1(d), or 13.1(e) (without any necessity of Lessor to give
notice of such default to Lessee), or (iv) in the event that Lessor has given to
Lessee three or more notices of default under paragraph 13.1(b) or paragraph
13.1(c), whether or not the defaults are cured, during the 12 month period of
time immediately prior to the time that Lessee attempts to exercise the subject
Option.

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

           (c) All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due and
timely exercise of the Option. If, after such exercise and during the term of
this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of Lessee
for a period of thirty (30) days after such obligation becomes due (without any
necessity of Lessor to give notice thereof to Lessee), or (ii) Lessee fails to
commence to cure a default specified in paragraph 13.1(c) within thirty (30)
days after the date that Lessor gives notice to Lessee of such default and/or
Lessee fails thereafter to diligently prosecute said cure to completion, or
(iii) Lessee commits a default described in paragraphs 13.1(a), 13.1(d) or
13.1(e) without any necessity of Lessor to give notice of such default to
Lessee), or (iv) Lessor gives to Lessee three or more notices of default under
paragraph 13.1(b), or paragraph 13.1(c), whether or not the defaults are cured.

40.  SECURITY MEASURES.  Lessee hereby acknowledges that Lessor shall have no
obligation whatsoever to provide guard service or other security measures for
the benefit of the Premises or the Industrial Center. Lessee assumes all
responsibility for the protection of Lessee, its agents, and invitees and the
property of Lessee and of Lessee's agents and invitees from acts of third
parties. Nothing herein contained shall prevent Lessor, at Lessor's sole option,
from providing security protection for the Industrial Center or any part
thereof, in which event the cost thereof shall be included within the definition
of Operating Expenses, as set forth in paragraph 4.2(b).

                                      -7-

41.  EASEMENTS.  Lessor reserves to itself the right, from time to time, to
grant such easements, rights and dedications that Lessor deems necessary or
desirable, and to cause the recordation of Parcel Maps and restrictions, so long
as such easements, rights, dedications, Maps and restrictions do not
unreasonably interfere with the use of the Premises by Lessee. Lessee shall sign
any of the aforementioned documents upon request of Lessor and failure to do so
shall constitute a material default of this Lease by Lessee without the need for
further notice to Lessee.

42.  PERFORMANCE UNDER PROTEST.  If at any time a dispute shall arise as to any
amount or sum of money to be paid by one party to the other under the provisions
hereof, the party against whom the obligation to pay the money is asserted shall
have the right to 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. It shall be adjudged
that there was no legal obligation on the part of said party to pay such sum or
any part thereof, said party shall be entitled to recover such sum or so much
thereof as it was not legally required to pay under the provisions of this
Lease.

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

44.  CONFLICT.  Any conflict between the printed provisions of this Lease and
the typewritten or handwritten provisions, if any, shall be controlled by the
typewritten or handwritten provisions.

45.  OFFER.  Preparation of this Lease by Lessor or Lessor's agent and
submission of same to Lessee shall not be deemed an offer to lease. This Lease
shall become binding upon Lessor and Lessee only when fully executed by Lessor
and Lessee.

46.  ADDENDUM.  Attached hereto is an addendum or addenda containing paragraphs
46.a through 46.f and Exhibit A which constitute a part of this Lease.

47.  Lessee shall pay $1.10 per square foot on space it is able to occupy. Upon
signature of lease, it will occupy 12,995 square feet and pay $14,295.00 per
month. After Lessee occupies all 19,335 square feet of space on the second
floor, it shall pay the full 421,268.00 per month. As Lessee occupies following
suites, its rent shall be increased the following amount:

     Suite #208 - 1,150 square feet: $1,265.00 per month

                                  46. ADDENDUM


46.a      Lessor shall arrange for a trash collection service for all tenants
on the premises of which the Premises are a part. Lessee shall pay its
proportionate share of the trash collection charges based on the proportionate
amount of building space occupied and trash load deposited in the common trash
containers by Lessee, as determined by Lessor. The fee to Lessee for trash
collection shall be $76.00* per month which may be increased if it is
determined that the fee charged is insufficient to remove Lessee's trash or if
trash rates are increased. Lessee shall not deposit any household trash or
other trash not specifically created in the normal course of operating its
business. No hazardous substances shall be disposed of in the trash bins or
anywhere on the premises. Fee shall increase at rate of $10 per 1,000 square
feet whenever Lessee occupies additional space through term of lease.

46.b      This lease is subject to all matters of record affecting the real
property of which the Premises are a part, including, without limitation,
covenants, conditions, restrictions, reservations, rights of way, easements and
exceptions, whether existing or hereafter created.

46.c      Subject to Lessee's right to deduct the cost of subleasing any space
occupied by Lessee, if Lessee, with Lessor's consent, as required by this
Lease, enters into a sublease of the entire Premises hereunder, and if Lessee
receives from the sublessee, rent or other consideration, either initially or
over the term of the sublease, in excess of the rent due Lessor under the
Lease, or if Lessee enters into a sublease of less than the entire Premises
hereunder and receives from the sublessee rent or other consideration in excess
of the rent due Lessor under this Lease fairly allocable to the portion of the
Premises so subleased after appropriate adjustments to assure that all other
payments called for under this Lease are appropriately taken into account, then
in either such event, Lessee shall pay to Lessor, as additional rent hereunder,
one half of the excess rent or other consideration so received by Lessee from
the sublessee. Such payment shall be made by Lessee to Lessor within ten (10)
days following receipt by Lessee from its sublessee of payment of such excess
rent or other consideration. A fully executed copy of all subleases must be
given to Lessor by Lessee.

46.d      ANNUAL C.P.I. ADJUSTMENT: Monthly Rent shall be adjusted upward every
year beginning on the first day of the month following the passage of the
initial twelve (12) calendar months of the lease term ("Adjustment Date"), and
on the first day of such month for each successive year of the lease term
thereafter. The adjustment shall be calculated by referring to the Consumer
Price Index as published by the United States Department of Labor, Bureau of
Labor Statistics, all Urban Consumers, All Items (1982/84=100 base), Los
Angeles/Anaheim/Riverside Area. The Base Period Index shall be the CPI for the
calendar month which is three (3) months prior to the month of the Estimated
Commencement Date set forth in Paragraph 3.1. The Base Period Index shall be
compared with the CPI (the "Comparison Index") for the same calendar month
which is three (3) months prior to the Adjustment Date. If the Comparison Index
is higher than the Base Period Index, then the Basic Monthly Rent payable by
Lessee hereunder shall be increased by 50% of the increase of the Comparison
Index over the Base Period Index. In no event shall the monthly rent be adjusted
downward. (By way of illustration only, if Lessee's commencement date was August
1, 1990, then the Base Period Index is that for May 1990 [Assume 249.1], the
Base Period Index would be compared with the Comparison Index for May 1991
[Assume 267.3], and because the Comparison Index for May 1991 is 7.3% higher,
the rent commencing on August 1, 1991, would be 3.66% higher).

Lessor shall notify Lessee of the increase in Basic Monthly Rent within ninety
(90) days after each Adjustment Date; provided, however, failure to give such
notice shall not constitute a waiver of Lessor's right to collect the Increased
Basic Monthly Rent. In the event the Bureau of Labor Statistics ceases to
publish this Consumer Price Index, the parties may agree to use any similar type
index or if they are unable to agree upon a substitute index, the parties shall
select an independent arbitrator who shall determine an alternate method of
computing the increased rental. Annual adjustment shall be at one-half (1/2) of
Consumer Price Index.

46.e      Merchandise sold on the Premises shall not be sold on a retail basis
to the general public. No warehouse, garage, clearance, or any other type of
sale to the general public is allowed on the Premises without the written
consent of Lessor and any required City permits.

46.f      HAZARDOUS SUBSTANCES.

          (1) Reportable Uses Require Consent. The term "HAZARDOUS SUBSTANCE"
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 or 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 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, by-products or fractions
thereof. Lessee shall not engage in any activity, in on 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 Law
(as defined in Section (d) below). "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. Reportable Use shall also include Lessee's being
responsible for the presence in, on or about the Premises of a Hazardous
Substance with respect to which any Applicable Law requires that a notice be
given to persons entering or occupying the Premises or


<PAGE>   16
46.f.     HAZARDOUS SUBSTANCES (CONT'D)

neighboring properties. Notwithstanding the foregoing, Lessee may, without
Lessor's prior consent, but in compliance with all Applicable Law, use any
ordinary and customary materials reasonably required to be used by Lessee in
the normal course of Lessee's business permitted on the Premises, 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 the use or presence of any
Hazardous Substance, activity or storage tank 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 therefrom
or therefor, including, but not limited to, the installation (and 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. In the
event that Lessee, at the expiration of the term of the Lease, or, if such term
has been extended, at the expiration of the applicable extended term, has not
vacated the premises and/or has not complied with all of the terms and
provisions contained in paragraph 46.f of the Lease, Lessee's obligation to pay
monthly rent and other monetary obligations to Lessor shall continue at one
hundred twenty-five percent (125%) of the rate in effect at such date of
termination until such time as Lessee has fully complied with all of the terms
and provisions in paragraph 46.f.

     (2)  DUTY TO INFORM LESSOR. If Lessee knows, or has reasonable cause to
believe, that a Hazardous Substance, or a condition involving or resulting from
same, has come to be located, in, on, under or about the Premises, other than
as previously consented to by Lessor, Lessee shall immediately give written
notice of such fact to Lessor. Lessee shall also immediately give Lessor 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, or persons entering or occupying the
Premises, concerning the presence, spill, release, discharge of, or exposure
to, any Hazardous Substance or contamination in, on or about the Premises,
including but not limited to all such documents as may be involved in any
Reportable Uses involving the Premises.

     (3)  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 loss of rents and/or damages,
liabilities, judgments, costs, claims, liens, expenses, penalties, permits and
attorney's and consultant's fees arising out of or involving any Hazardous
Substance or storage tank brought onto the Premises by or for Lessee or under
Lessee's control. Lessee's obligations under this Paragraph 46.f 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 consultant's and attorney's fees and testing),
removal, remediation, restoration and/or abatement thereof, or of any
contamination therein involved, and shall survive the expiration of 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 or storage tanks, unless
specifically so agreed by Lessor in writing at the time of such agreement.

     (4)  LESSEE'S COMPLIANCE WITH LAW. Except as otherwise provided in this
Lease, Lessee shall, at Lessee's sole cost and expense, fully, diligently and
in a timely manner, comply with all "APPLICABLE LAW," which term is used in
this Lease to include 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 ground water conditions, and (iii) the use,
generation, manufacture, production, installation, maintenance, removal,
transportation, storage, spill or release of any Hazardous Substance or storage
tank), now in effect or which may hereafter come into effect, and whether or not
reflecting a change in policy from any previously existing policy. 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 Law 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 Law.

     (5)  INSPECTION; COMPLIANCE. Lessor and Lessor's Lender(s) (as defined in
Paragraph 7.2(b) shall have the right to enter the Premises with prior notice
at reasonable times, for the purpose of inspecting the condition of the
Premises and for verifying compliance by Lessee with this Lease and all
Applicable Laws (as defined in Section (d) above), and to employ experts and/or
consultants in connection therewith and/or to advise Lessor with respect to
Lessee's activities, including but not limited to the installation, operation,
use, monitoring, maintenance, or removal of any Hazardous Substance or storage
tank on or from the Premises. The costs and expenses of any such inspections
shall be paid by the party requesting same, unless a Default or Breach of this
Lease, violation of Applicable Law, or a contamination, caused or materially
contributed to by Lessee is found to exist 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 any 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.

RE: CONSUMER PRICE INDEX (C.P.I.) ADJUSTMENT - 359 Van Ness Way,
Torrance, Ca.

Dear Mr. Kopycki:

According to the terms of your lease agreement, you have a rent adjustment on
February 1, 2000.

This rental adjustment is based on the change in the Consumer Price Index
(C.P.I.) for the period from November 1998 to November 1999. The C.P.I. for
this period has increased 2.3% representing an increase of $590.00 per month.
However, your lease provides for the increase to be 50% of the comparison
index. This will reduce your increase to $295.00

Therefor, effective February 1, 2000 your rent will be $25,927.00 per month. We
will send you a statement reflecting the increase.

Sincerely,

SURF MANAGEMENT ASSOCIATES

Lessor's agents, has made any oral or written representations or warranties with
respect to said matters other than as set forth in this Lease.

     2.5 LESSEE AS PRIOR OWNER/OCCUPANT. The warranties made by Lessor in this
Paragraph 2 shall be of no force or effect if immediately prior to the date set
forth in Paragraph 1.1 Lessee was the owner or occupant of the Premises. In such
event, Lessee shall, at Lessee's sole cost and expense, correct any
non-compliance of the Premises with said warranties.

     2.6 VEHICLE PARKING. Lessee shall be entitled to use the number of
Unreserved Parking Spaces and Reserved Parking Spaces specified in Paragraph
1.2(b) on those portions of the Common Areas designated from time to time by
Lessor for parking for the Industrial Center. Lessee shall not use more parking
spaces than said number. Said parking spaces shall be used for parking by
vehicles no larger than full-size passenger automobiles or pick-up trucks,
herein called "PERMITTED SIZE VEHICLES." Vehicles other than Permitted Size
Vehicles shall be parked and loaded or unloaded as directed by Lessor in the
Rules and Regulations (as defined in Paragraph 40) issued by Lessor. (Also see
Paragraph 2.9.)

              (a) Lessee shall not permit or allow any vehicles that belong to
or are controlled by Lessee or Lessee's employees, suppliers, shippers,
customers, contractors or invitees to be loaded, unloaded, or parked in areas
other than those designated by Lessor for such activities.

              (b) If Lessee permits or allows any of the prohibited activities
described in this Paragraph 2.6, then Lessor shall have the right, without
notice, in addition to such other rights and remedies that it may have, to
remove or tow away the vehicle involved and charge the cost to Lessee, which
cost shall be immediately payable upon demand by Lessor.

              (c) Lessor shall at the Commencement Date of this Lease, provide
the parking facilities required by Applicable Law.

     2.7 COMMON AREAS - DEFINITION. The term "COMMON AREAS" is defined as all
areas and facilities outside the Premises and within the exterior boundary line
of the Industrial Center and interior utility raceways within the Premises that
are provided and designated by the Lessor from time to time for the general
non-exclusive use of Lessor, Lessee and other lessees of the Industrial Center
and their respective employees, suppliers, shippers, customers, contractors and
invitees, including parking areas, loading and unloading areas, trash areas,
roadways, sidewalks, walkways, parkways, driveways and landscaped areas.

     2.8 COMMON AREAS - LESSEE'S RIGHTS. Lessor hereby grants to Lessee, for
the benefit of Lessee and its employees, suppliers, shippers, contractors,
customers and invitees, during the term of this Lease, the non-exclusive right
to use, in common with others entitled to such use, the Common Areas as they
exist from time to time, subject to any rights, powers, and privileges reserved
by Lessor under the terms hereof or under the terms of any rules and regulations
or restrictions governing the use of the Industrial Center. Under no
circumstances shall the right herein granted to use the Common Areas be deemed
to include the right to store any property, temporarily or permanently, in the
Common Areas. Any such storage shall be permitted only by the prior written
consent of Lessor or Lessor's designated agent, which consent may be revoked at
any time. In the event that any unauthorized storage shall occur then Lessor
shall have the right, without notice, in addition to such other rights and
remedies that it may have, to remove the property and charge the cost to Lessee,
which cost shall be immediately payable upon demand by Lessor.

     2.9 COMMON AREAS - RULES AND REGULATIONS. Lessor or such other person(s)
as Lessor may appoint shall have the exclusive control and management of the
Common Areas and shall have the right, from time to time, to establish, modify,
amend and enforce reasonable Rules and Regulations with respect thereto in
accordance with Paragraph 40. Lessee agrees to abide by and conform to all such
Rules and Regulations, and to cause its employees, suppliers, shippers,
customers, contractors and invitees to so abide and conform. Lessor shall not be
responsible to Lessee for the non-compliance with said rules and regulations by
other lessees of the Industrial Center.

     2.10 COMMON AREAS - CHANGES. Lessor shall have the right, in Lessor's sole
discretion, from time to time:

              (a) To make changes to the Common Areas, including, without
limitation, changes in the location, size, shape and number of driveways,
entrances, parking spaces, parking areas, loading and unloading areas, ingress,
egress, direction of traffic, landscaped areas, walkways and utility raceways;

              (b) To close temporarily any of the Common Areas for maintenance
purposes so long as reasonable access to the Premises remains available;

              (c) To designate other land outside the boundaries of the
Industrial Center to be a part of the Common Areas;

              (d) To add additional buildings and improvements to the Common
Areas;

              (e) To use the Common Areas while engaged in making additional
improvements, repairs or alterations to the Industrial Center, or any portion
thereof; and

              (f) To do and perform such other acts and make such other changes
in, to or with respect to the Common Areas and Industrial Center as Lessor may,

3.   TERM.

     3.1 TERM. The Commencement Date, Expiration Date and Original Term of this
Lease are as specified in Paragraph 1.3.

     3.2 EARLY POSSESSION. If an Early Possession Date is specified in Paragraph
1.4 and if Lessee totally or partially occupies the Premises after the Early
Possession Date but prior to the Commencement Date, the obligation 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 carry the insurance
required by Paragraph 8) shall be in effect during such period. Any such early
possession shall not affect nor advance the Expiration Date of the Original
Term.

     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, 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 Lessor delivers possession of the Premises to
Lessee. If possession of the Premises is not delivered to Lessee within sixty
(60) days after the Commencement Date, Lessee may, at its option, by notice in
writing to Lessor within ten (10) days after the end of said sixty (60) day
period, cancel this Lease, in which event the parties shall be discharged from
all obligations hereunder; provided further, however, that if such written
notice of Lessee is not received by Lessor within said ten (10) day period,
Lessee's right to cancel this Lease hereunder shall terminate and be of no
further force or effect. Except as may be otherwise provided, and regardless of
when the Original Term actually commences, if possession is not tendered to
Lessee when required by this Lease and Lessee does not terminate this Lease, as
aforesaid, the period free of the obligation to pay Base Rent, if any, that
Lessee would otherwise have enjoyed shall run from the date of delivery of
possession and continue for a period equal to the period during which the Lessee
would have otherwise enjoyed under the terms hereof, but minus any days of delay
caused by the acts, changes or omissions of Lessee. See Para. 49.g

4.   RENT.

     4.1 BASE RENT. Lessee shall pay Base Rent and other rent or charges, as the
same may be adjusted from time to time, to Lessor in lawful money of the United
States, without offset or deduction, on or before the day on which it is due
under the terms of this Lease. Base Rent and all other rent and charges for any
period during the term hereof which is for less than one full month shall be
prorated based upon a 30 day 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.

                    (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) Any increase above the Base Real Property Taxes (as
defined in Paragraph 10.2(b)) for the Building and the Common Areas.

                    (vi) Any "Insurance Cost Increase" (as defined in Paragraph
8.1).

                    (vii) The cost of insurance carried by Lessor with respect
to the Common Areas.

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

                    (xi) 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 this Lease to provide
the same or some of them.

              (d) Lessee's Share of Common Area Operating Expenses 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 Expenses 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, Lessee shall be credited the amount of such over-



                                      -2-
<PAGE>   21
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, of 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 1.8, 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.

              (b) Lessor hereby agrees to not unreasonably withhold or delay its
consent to any written request by Lessee, Lessee's assignees or subtenants, and
by prospective assignees and subtenants of Lessee, its assignees and subtenants,
for a modification of said Permitted Use, so long as the same will not impair
the structural integrity of the improvements on the Premises or in the Building
or the mechanical or electrical systems therein, does not conflict with uses by
other lessees, is not significantly more burdensome to the Premises or the
Building and the improvements thereon, and is otherwise permissible pursuant to
this Paragraph 6. If Lessor elects to withhold such consent, Lessor shall within
five (5) business days after such request give a written notification of same,
which notice shall include an explanation of Lessor's reasonable objections to
the change in use.

     6.2 HAZARDOUS SUBSTANCES.

              (a) REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS
SUBSTANCE" 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 or 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 with prior notice at reasonable times, 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 costs 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 INSTALLATIONS, 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, including, without limiting
the generality of the foregoing, all equipment or facilities specifically
serving the Premises, such as electrical, lighting facilities, boilers, fired or
unfired pressure vessels, fire hose connections if within the Premises,
fixtures, interior walls, interior surfaces of 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)

              (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

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.

              (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. Lessor 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 PREMIUM INCREASES.

              (a) As used herein, the term "INSURANCE COST INCREASE" is defined
as any increase in the actual cost of the insurance applicable to the Building
and required to be carried by Lessor pursuant to Paragraphs 8.2(b), 8.3(a) and
8.3(b), ("REQUIRED INSURANCE"), over and above the base Premium, as hereinafter
defined, calculated on an annual basis. "Insurance Cost Increase" shall
include, but not be limited to, requirements of the holder of a mortgage or
deed of trust covering the Premises, increased valuation of the Premises,
and/or a general premium rate increase. The term "Insurance Cost Increase"
shall not, however, include any premium increases resulting from the nature of
the occupancy of any other lessee of the Building. If the parties insert a
dollar amount in Paragraph 1.9, such amount shall be considered the "BASE
PREMIUM." If a dollar amount has not been inserted in Paragraph 1.9 and if the
Building has been previously occupied during the twelve (12) month period
immediately preceding the Commencement Date, the "Base Premium" shall be the
annual premium applicable to such twelve (12) month period. If the Building was
not fully occupied during such twelve (12) month period, the "Base Premium"
shall be the lowest annual premium reasonably obtainable for the Required
Insurance as of the Commencement Date, assuming the most nominal use possible
of the Building. In no event, however, shall Lessee be responsible for any
portion of the premium cost attributable to liability insurance coverage in
excess of $1,000,000 procured under Paragraph 8.2(b).

              (b) Lessee shall pay any Insurance Cost Increase to Lessor
pursuant to Paragraph 4.2. Premiums for policy periods commencing prior to, or
extending beyond, the term of this Lease shall be prorated 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 limit coverage in an amount not less than $1,000,000 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 and/or earthquake unless required by a Lender or included in the Base
Premium), 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.


                                      -4-
<PAGE>   23

              (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 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 cancelable 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 the negligent acts of Lessor or Lessor's agents,
employees, contractors, customers or invitees. 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, 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. Except for the negligent acts of
Lessor or Lessor's agents, employees, contractors, customers or invitees. 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.


                                      -5-
<PAGE>   24

              (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
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 Lessor 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(a), applicable to the Industrial Center, and except as
otherwise provided in Paragraph 10.3, any increases in such amounts over the
Base Real Property Taxes 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.

              (a) 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.

              (b) As used herein, the term "BASE REAL PROPERTY TAXES" shall be
the amount of Real Property Taxes, which are assessed against the Premises,
Building or Common Areas in the calendar year during which the Lease is
executed. 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 Alterations 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.

              (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
remainder 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) alter 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.


                                      -6-
<PAGE>   25
              (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 six (6) 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. See Paragraph #49.c

     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 sublessee, be deemed liable to the sublessee
for any failure of Lessee to perform and comply with any of Lessee's obligations
to such sublessee under such Sublease. Lessee hereby irrevocably authorizes and
directs any such sublessee, upon receipt of a written notice from Lessor stating
that a 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 or 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 Lessee's interest in this Lease, where
possession is not restored to Lessee within thirty (30) days; or (iv) the
attachment, execution or other judicial seizure of substantially all of Lessee's
assets located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; 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 attorneys' 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 pro-


                                      -7-
<PAGE>   26
ceeding 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 Subparagraphs
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 becomes 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.

              (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.

     13.5 BREACH BY LESSOR. Lessor shall not be deemed in breach of this Lease
unless Lessor fails 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.

     15.2

     15.3

     15.4

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 by 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 or 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,
which 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 form 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 two hundred percent
(200%) 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 (1) 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 one hundred eighty (180) 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.


                                      -9-
<PAGE>   28

     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.

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 later 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) Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary: (i) 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 Default 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 parties shall be the joint and several
responsibility of all persons or entities named herein as such Lessor or Lessee.

50. All existing leases at 357 Van Ness Way, except Suite 200, will be
cancelled when Lessee fully vacates each Suite. The rent will be prorated based
on actual date each individual suite is vacated.

51. The items listed on the repair plan dated 9/26/96 will be fixed at no
expense to Mkyotronx. All drywall damage will be repaired and the walls made
ready for painting. All building systems such as plumbing, HVAC and electrical
will be in good operating condition. All other tenant improvements shall be at
Lessee's expense, including paint or carpet, if desired.

                                  49 ADDENDUM


49.a  TRASH: Lessor shall arrange for a trash collection service for all tenants
on the premises of which the Premises are a part. Lessee shall pay its
proportionate share of the trash collection charges based on the proportionate
amount of building space occupied and trash load deposited in the common trash
containers by Lessee, as determined by Lessor. The fee to Lessee for trash
collection shall be $280.00 per month which may be increased if it is determined
that the fee charged is insufficient to remove Lessee's trash or if trash rates
are increased. Lessee shall not deposit any household trash or other trash not
specifically created in the normal course of operating its business. No
hazardous substances shall be disposed of in the trash bins or anywhere on the
premises.

49.b  This lease is subject to all matters of record affecting the real
property of which the Premises are a part, including without limitation,
covenants, conditions, restrictions, reservations, rights of way, easements and
exceptions, whether existing or hereafter created.

49.c  SUBLEASING: If Lessee, with Lessor's consent, as required by this Lease,
enters into a sublease of the entire Premises, and if Lessee receives from the
Sublessee, rent or other consideration, either initially or over the term of
the sublease, in excess of the rent due Lessor under the Lease, of if Lessee
enters into a sublease of less than the entire Premises and receives from the
Sublessee rent or other consideration in excess of the rent due Lessor under
this Lease fairly allocable to the portion of the Premises so subleased after
appropriate adjustments to assure that all other payments called for under this
Lease are appropriately taken into account, then in either such event, Lessee
shall pay to Lessor, as additional rent, one half of the excess rent or other
consideration so received by Lessee from the Sublessee. Such payment shall be
made by Lessee to Lessor within ten (10) days following receipt by Lessee from
its Sublessee of payment of such excess rent or other consideration. A fully
executed copy of all subleases must be given to Lessor by Lessee.

49.d CPI ADJUSTMENT(S) (CPI): The monthly rent for each month of the adjustment
period(s) specified below shall be increased using the method indicated below:

On (Fill in CPI Adjustment Date(s)): February, 1, 1998, 1999, 2000 and 2001 (the
monthly rent payable under paragraph 1.5 ("Base Rent") of the attached Lease
shall be adjust by 50% of the change, if any, from the Base Rent Month specified
below, in the Consumer Price Index of the Bureau of Labor Statistics of the U.S.
Department of Labor for all Urban Consumers for Los Angeles/Anaheim/Riverside
Area. All items (1982/84 -100 base), herein referred to as "C.P.I."

The monthly rent payable shall be calculated as follows: the Base Rent set forth
in paragraph 1.5 of the attached Lease shall be multiplied by 50% of the
fraction the numerator of which shall be the C.P.I. of the calendar month three
(3) months prior to the month(s) specified above during which the adjustment is
to take effect, and the denominator of which shall be the C.P.I. of the calendar
month which is three (3) months prior to the first month of the term of this
Lease as set forth in paragraph 1.3 ("Base Month"). The sum so calculated shall
constitute the new monthly rent, but in no event, shall any such new monthly
rent be less than the rent payable for the month immediately preceding the date
for rent adjustment.

In the event the compilation and/or publication of the C.P.I. shall be
transferred to any other governmental department or bureau or agency or shall
be discontinued, then the Index most nearly the same as the C.P.I. shall be
used to make such calculation. In the event that Lessor and Lessee cannot agree
on such alternative Index, then the matter shall be submitted for decision to
the American Arbitration Association in accordance with the then rules of said
association and the decision of the arbitrators shall be biding upon the
parties. The cost of said Arbitrators shall be paid equally by Lessor and
Lessee.

Annual adjustment shall be at one-half (1/2) of the Consumer Price Index.

49.e  PUBLIC SALES: Merchandise sold on the Premises shall not be sold on a

3.   TERM.

     3.1 TERM. The Commencement Date, Expiration Date and Original Term of this
Lease are as specified in Paragraph 1.3.

     3.2 EARLY POSSESSION. If an Early Possession Date is specified in Paragraph
1.4 and if Lessee totally or partially occupies the Premises after the Early
Possession Date but prior to the Commencement Date, the obligation 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 carry the insurance
required by Paragraph 8) shall be in effect during such period. Any such early
possession shall not affect nor advance the Expiration Date of the Original
Term.

     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, 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 Lessor delivers possession of the Premises to
Lessee. If possession of the Premises is not delivered to Lessee within sixty
(60) days after the Commencement Date, Lessee may, at its option, by notice in
writing to Lessor within ten (10) days after the end of said sixty (60) day
period, cancel this Lease, in which event the parties shall be discharged from
all obligations hereunder; provided further, however, that if such written
notice of Lessee is not received by Lessor within said ten (10) day period,
Lessee's right to cancel this Lease hereunder shall terminate and be of no
further force or effect. Except as may be otherwise provided, and regardless of
when the Original Term actually commences, if possession is not tendered to
Lessee when required by this Lease and Lessee does not terminate this Lease, as
aforesaid, the period free of the obligation to pay Base Rent, if any, that
Lessee would otherwise have enjoyed shall run from the date of delivery of
possession and continue for a period equal to the period during which the Lessee
would have otherwise enjoyed under the terms hereof, but minus any days of delay
caused by the acts, changes or omissions of Lessee. See Para. 49.g

4.   RENT.

     4.1 BASE RENT. Lessee shall pay Base Rent and other rent or charges, as the
same may be adjusted from time to time, to Lessor in lawful money of the United
States, without offset or deduction, on or before the day on which it is due
under the terms of this Lease. Base Rent and all other rent and charges for any
period during the term hereof which is for less than one full month shall be
prorated based upon a 30 day 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.

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

following:

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

the Building or the Common Areas.

                    (xi) 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 this Lease to provide
the same or some of them.

              (d) Lessee's Share of Common Area Operating Expenses 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 Expenses 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, Lessee shall be credited the amount of such over-



                                      -2-
<PAGE>   34
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

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, of 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 1.8, 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.

              (b) Lessor hereby agrees to not unreasonably withhold or delay its
consent to any written request by Lessee, Lessee's assignees or subtenants, and
by prospective assignees and subtenants of Lessee, its assignees and subtenants,
for a modification of said Permitted Use, so long as the same will not impair
the structural integrity of the improvements on the Premises or in the Building
or the mechanical or electrical systems therein, does not conflict with uses by
other lessees, is not significantly more burdensome to the Premises or the
Building and the improvements thereon, and is otherwise permissible pursuant to
this Paragraph 6. If Lessor elects to withhold such consent, Lessor shall within
five (5) business days after such request give a written notification of same,
which notice shall include an explanation of Lessor's reasonable objections to
the change in use.

SUBSTANCE" 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 or 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, 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 costs 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 INSTALLATIONS, 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 of 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 and hose (if located in the
Common Areas) or other automatic fire extinguishing system including fire alarm
and/or smoke detection


                                      -3-
<PAGE>   35
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.

              (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. Lessor 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 PREMIUM INCREASES.

              (a) As used herein, the term "INSURANCE COST INCREASES" is
defined as any increases in the actual cost of the insurance applicable to the
Building and required to be carried by Lessor pursuant to Paragraphs 8.2(b),
8.3(a) and  8.3(b). ("REQUIRED INSURANCE"), over and above the Base Premium, as
hereinafter defined, calculated on an annual basis. "Insurance Cost Increase"
shall include, but not be limited to, requirements of the holder of a mortgage
or deed of trust covering the Premises, increased valuation of the Premises,
and/or a general premium rate increase. The term "Insurance Cost Increase"
shall not, however, include any premium increases resulting from the nature of
the occupancy of any other lessee of the Building. If the parties insert a
dollar amount in Paragraph 1.9, such amount shall be considered the "BASE
PREMIUM." If a dollar amount has not been inserted in Paragraph 1.9 and if the
Building  has been previously occupied during the twelve (12) month period
immediately preceding the Commencement Date, the "Base Premium" shall be the
annual premium applicable to such twelve (12) month period. If the Building was
not fully occupied during such twelve (12) month period, the "Base Premium"
shall be the lowest annual premium reasonably obtainable for the Required
Insurance as of the Commencement Date, assuming the most nominal use possible
of the Building. In no event, however, shall Lessee be responsible for any
portion of the premium cost attributable to liability insurance coverage in
excess of $1,000,000 procured under Paragraph 8.2(b).

              (b) Lessee shall pay any Insurance Cost Increase to Lessor
pursuant to Paragraph 4.2. Premiums for policy periods commencing prior to, or
extending beyond, the term of this Lease shall be prorated 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 limit coverage in an amount not less than $1,000,000 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 and/or earthquake unless required by a Lender or included in the Base
Premium), 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.


                                      -4-
<PAGE>   36

              (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 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 cancelable 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.


                                      -5-
<PAGE>   37

              (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
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 Lessor 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.

              (a) 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.

              (b) As used herein, the term "BASE REAL ESTATE PROPERTY TAXES"
shall be the amount of Real Property Taxes, which are assessed against the
Premises, Building or Common Areas in the calendar year during which the Lease
is executed. 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 Alterations 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.

              (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
remainder of the Lease term shall be increased in the same ratio as the new
rental bears to the Base Rent in effect immediately prior 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) alter 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.


                                      -6-
<PAGE>   38
              (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 six (6) 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. See Paragraph #49.c

     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 sublessee, be deemed liable to the sublessee
for any failure of Lessee to perform and comply with any of Lessee's obligations
to such sublessee under such Sublease. Lessee hereby irrevocably authorizes and
directs any such sublessee, upon receipt of a written notice from Lessor stating
that a 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 or 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 Lessee's interest in this Lease, where
possession is not restored to Lessee within thirty (30) days; or (iv) the
attachment, execution or other judicial seizure of substantially all of Lessee's
assets located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; 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 attorneys' 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 pro-


                                      -7-
<PAGE>   39
ceeding 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 Subparagraphs
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 becomes 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.

              (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.

     13.5 BREACH BY LESSOR. Lessor shall not be deemed in breach of this Lease
unless Lessor fails 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.

     15.1 PROCURING CAUSE. The Broker(s) named in Paragraph 1.10 is/are the
procuring cause of this Lease.

     15.4

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 by 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 or 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 monies or damages due Lessor, notwithstanding any
qualifying statements or conditions made by Lessee in connection therewith,
which 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 form 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 two hundred percent
(200%) 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 (1) 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 one hundred eighty (180) 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.


                                      -9-
<PAGE>   41

     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.

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 later option cannot be exercised unless the prior
Options to extend or renew this Lease have been validly exercised.

Lessee three (3) or more notices of separate Default under Paragraph 13.1 during

              (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

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.

Sublessee rent or other consideration in excess of the rent due Lessor under
this Lease fairly allocable to the portion of the Premises so subleased after
appropriate adjustments to assure that all other payments called for under this
Lease are appropriately taken into account, then in either such event, Lessee
shall pay to Lessor, as additional rent, one half of the excess rent or other
consideration so received by Lessee from the Sublessee. Such payment shall be

              (c) To designate other land outside the boundaries of the
Industrial Center to be a part of the Common Areas;

              (d) To add additional buildings and improvements to the Common
Areas;

              (e) To use the Common Areas while engaged in making additional
improvements, repairs or alterations to the Industrial Center, or any portion
thereof; and

              (f) To do and perform such other acts and make such other changes
in, to or with respect to the Common Areas and Industrial Center as Lessor may,
in the exercise of sound business judgment, deem to be appropriate.

3.   TERM.

     3.1 TERM. The Commencement Date, Expiration Date and Original Term of this
Lease are as specified in Paragraph 1.3.

     3.2 EARLY POSSESSION. If an Early Possession Date is specified in Paragraph
1.4 and if Lessee totally or partially occupies the Premises after the Early
Possession Date but prior to the Commencement Date, the obligation 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 carry the insurance
required by Paragraph 8) shall be in effect during such period. Any such early
possession shall not affect nor advance the Expiration Date of the Original
Term.

     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, 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 Lessor delivers possession of the Premises to
Lessee. If possession of the Premises is not delivered to Lessee within sixty
(60) days after the Commencement Date, Lessee may, at its option, by notice in
writing to Lessor within ten (10) days after the end of said sixty (60) day
period, cancel this Lease, in which event the parties shall be discharged from
all obligations hereunder; provided further, however, that if such written
notice of Lessee is not received by Lessor within said ten (10) day period,
Lessee's right to cancel this Lease hereunder shall terminate and be of no
further force or effect. Except as may be otherwise provided, and regardless of
when the Original Term actually commences, if possession is not tendered to
Lessee when required by this Lease and Lessee does not terminate this Lease, as
aforesaid, the period free of the obligation to pay Base Rent, if any, that
Lessee would otherwise have enjoyed shall run from the date of delivery of
possession and continue for a period equal to the period during which the Lessee
would have otherwise enjoyed under the terms hereof, but minus any days of delay
caused by the acts, changes or omissions of Lessee. See Para. 49.g.

4.   RENT.

     4.1 BASE RENT. Lessee shall pay Base Rent and other rent or charges, as the
same may be adjusted from time to time, to Lessor in lawful money of the United
States, without offset or deduction, on or before the day on which it is due
under the terms of this Lease. Base Rent and all other rent and charges for any
period during the term hereof which is for less than one full month shall be
prorated based upon a 30 day month. 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.

                    (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) Any increase above the Base Real Property Taxes (as
defined in Paragraph 10.2(b)) for the Building and the Common Areas.

                    (vi) Any "Insurance Cost Increase" (as defined in Paragraph
8.1).

                    (vii) The cost of insurance carried by Lessor with respect
to the Common Areas.

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

                    (ix) 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 this Lease to provide
the same or some of them.

              (d) Lessee's Share of Common Area Operating Expenses 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 Expenses 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, Lessee shall be credited the amount of such over-



                                      -2-
<PAGE>   48
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, of 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 1.8, 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.

              (b) Lessor hereby agrees to not unreasonably withhold or delay its
consent to any written request by Lessee, Lessee's assignees or subtenants, and
by prospective assignees and subtenants of Lessee, its assignees and subtenants,
for a modification of said Permitted Use, so long as the same will not impair
the structural integrity of the improvements on the Premises or in the Building
or the mechanical or electrical systems therein, does not conflict with uses by
other lessees, is not significantly more burdensome to the Premises or the
Building and the improvements thereon, and is otherwise permissible pursuant to
this Paragraph 6. If Lessor elects to withhold such consent, Lessor shall within
five (5) business days after such request give a written notification of same,
which notice shall include an explanation of Lessor's reasonable objections to
the change in use.

     6.2 HAZARDOUS SUBSTANCES.

              (a) REPORTABLE USES REQUIRE CONSENT. The term "HAZARDOUS
SUBSTANCE" 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 or 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, 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 costs 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 INSTALLATIONS, 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 of 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 and hose (if located in the
Common Areas) or other automatic fire extinguishing system including fire alarm
and/or smoke detection


                                      -3-
<PAGE>   49
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.

              (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. Lessor 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 PREMIUM INCREASES.

              (a) As used herein, the term "INSURANCE COST INCREASE" is defined
as any increase in the actual cost of the insurance applicable to the Building
and required to be carried by Lessor pursuant to Paragraphs 8.2(b), 8.3(a) and
8.3(b), ("REQUIRED INSURANCE"), over and above the Base Premium, as hereinafter
defined, calculated on an annual basis. "Insurance Cost Increase" shall
include, but not be limited to, requirements of the holder of a mortgage or
deed of trust covering the Premises, increased valuation of the Premises,
and/or a general premium rate increase. The term "Insurance Cost Increase"
shall not, however, include any premium increases resulting from the nature of
the occupancy of any other lessee of the Building. If the parties insert a
dollar amount in Paragraph 1.9, such amount shall be considered the "BASE
PREMIUM." If a dollar amount has not been inserted in Paragraph 1.9 and if the
Building has been previously occupied during the twelve (12) month period
immediately preceding the Commencement Date, the "Base Premium" shall be the
annual premium applicable to such twelve (12) month period. If the Building was
not fully occupied during such twelve (12) month period, the "Base Premium"
shall be the lowest annual premium reasonably obtainable for the Required
Insurance as of the Commencement Date, assuming the most nominal use possible
of the Building. In no event, however, shall Lessee be responsible for any
portion of the premium cost attributable to liability insurance coverage in
excess of $1,000,000 procured under Paragraph 8.2(b).

              (b) Lessee shall pay any Insurance Cost Increase to Lessor
pursuant to Paragraph 4.2. Premiums for policy periods commencing prior to, or
extending beyond, the term of this Lease shall be prorated 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 limit coverage in an amount not less than $1,000,000 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 and/or earthquake 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.


                                      -4-
<PAGE>   50

              (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 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 cancelable 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.


                                      -5-
<PAGE>   51

              (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
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 Lessor 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.

          (a) 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.

          (b) As used herein, the term "BASE REAL PROPERTY TAXES" shall be the
amounts of Real Property Taxes, which are assessed against the Premises,
Buildings or Common Areas in the calendar year during which the Lease is
executed. 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 Alterations 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.

              (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
remainder of the Lease term shall be increased in the same ratio as the new
rental bears to the Base Rent in effect immediately prior 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) alter 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.

<PAGE>   52
              (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 six (6) 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. See Paragraph #49.c

     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 sublessee, be deemed liable to the sublessee
for any failure of Lessee to perform and comply with any of Lessee's obligations
to such sublessee under such Sublease. Lessee hereby irrevocably authorizes and
directs any such sublessee, upon receipt of a written notice from Lessor stating
that a 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 or 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 Lessee's interest in this Lease, where
possession is not restored to Lessee within thirty (30) days; or (iv) the
attachment, execution or other judicial seizure of substantially all of Lessee's
assets located at the Premises or of Lessee's interest in this Lease, where such
seizure is not discharged within thirty (30) days; 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 attorneys' 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 pro-


                                      -7-
<PAGE>   53
ceeding 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 Subparagraphs
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 becomes 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.

              (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.

     13.5 BREACH BY LESSOR. Lessor shall not be deemed in breach of this Lease
unless Lessor fails 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.

     15.3

     15.4

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 by 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 or 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,
which 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 form 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 two hundred percent
(200%) 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 one hundred eighty (180) 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.


                                      -9-
<PAGE>   55

     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.

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 later 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) Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary: (i) 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 parties shall be the joint and several
responsibility of all persons or entities named herein as such Lessor or Lessee.

50. Lessee shall occupy premises in as is condition.

49.a  TRASH: Lessor shall arrange for a trash collection service for all tenants
on the premises of which the Premises are a part. Lessee shall pay its
proportionate share of the trash collection charges based on the proportionate
amount of building space occupied and trash load deposited in the common trash
containers by Lessee, as determined by Lessor. The fee to Lessee for trash
collection shall be $25.00 per month which may be increased if it is determined
that the fee charged is insufficient to remove Lessee's trash or if trash rates
are increased. Lessee shall not deposit any household trash or other trash not
specifically created in the normal course of operating its business. No
hazardous substances shall be disposed of in the trash bins or anywhere on the
premises.

49.b  This lease is subject to all matters of record affecting the real
property of which the Premises are a part, including without limitation,
covenants, conditions, restrictions, reservations, rights of way, easements and
exceptions, whether existing or hereafter created.

49.c  SUBLEASING: If Lessee, with Lessor's consent, as required by this Lease,
enters into a sublease of the entire Premises, and if Lessee receives from the
Sublessee, rent or other consideration, either initially or over the term of
the sublease, in excess of the rent due Lessor under the Lease, or if Lessee
enters into a sublease of less than the entire Premises and receives from the
Sublessee rent or other consideration in excess of the rent due Lessor under
this Lease fairly allocable to the portion of the Premises so subleased after
appropriate adjustments to assure that all other payments called for under this
Lease are appropriately taken into account, then in either such event, Lessee
shall pay to Lessor, as additional rent, one half of the excess rent or other
consideration so received by Lessee from the Sublessee. Such payment shall be
made by Lessee to Lessor within ten (10) days following receipt by Lessee from
its Sublessee of payment of such excess rent or other consideration. A fully
executed copy of all subleases must be given to Lessor by Lessee.

49.d

49.e  PUBLIC SALES: Merchandise sold on the Premises shall not be sold on a

terms of this Lease, and not to disclose such terms to any other occupants of

49.g  DELAY IN POSSESSION: Notwithstanding paragraph 3.2, if the Commencement
Date is delayed two (2) weeks or more, there shall be a corresponding shift in
the ending date of the lease. If the Commencement Date is delayed less than (2)
weeks, the ending date shall remain unchanged.

49.h  SECURITY CAMERAS: Any Lessor supplied notices on the buildings regarding
security cameras, and any Lessor supplied cameras themselves are intended as a

be responsible for informing its employees, agents, contractors, etc. that
Lessor supplied cameras should not be relied upon for security.

49.i  SURRENDER/RESTORATION: In addition to the terms and conditions of
Paragraph 74(c), upon vacating the premises Lessee shall, if necessary,
shampoo the carpeting, clean the restrooms and remove all debris. Should Lessee
elect not to perform these tasks, Lessor shall do so and charge a reasonable
fee for the service.

those interior and exterior portions of the Building and such other areas,

Lease; were installed by Landlord during the Term of this Lease to comply with
the requirements or directives of a government, quasi-government or regulatory
agency or authority; were installed by Landlord during the Term of this Lease
with the intent of reducing Operating Expenses; were installed by Landlord

        1.5 Notwithstanding the foregoing, those terms defined in Articles 1.1
through 1.4, above are subject to modification, revision or alteration by other
terms and conditions of this Lease, addenda, exhibits and other attachments
hereto.


ARTICLE 2 - TERM

        2.1 The "Initial Term" of this Lease shall commence on the earliest
Commencement Date and continue to the Termination Date, unless sooner terminated
as otherwise provided herein. The "Term" of this Lease shall include the Initial
Term and any other period of Tenant's occupancy resulting either from Tenant's
holding over with Landlord's consent (pursuant to Article 29.2), or from
Tenant's exercise of an express option to renew, re-lease or extend the Term, or
other express agreement to extend the Term, all made in accordance with this
Lease (or a modification or addendum thereto made in accordance with this
Lease). Unless expressly stated to the contrary herein, any and all references
herein to "months" during the Term shall be deemed to refer to full calendar
months of the Term, beginning the earliest Commencement Date (if the
Commencement Date is the first day of a calendar month) or the first day of the
first full calendar month after the earliest Commencement Date (if the
Commencement Date is not the first day of a calendar month).

<PAGE>   6

ARTICLE 3 - BASIC MONTHLY RENT

        3.1 The first installment of Basic Monthly Rent is due on or before the
execution of this Lease. All other installments of Basic Monthly Rent are
payable in advance on the first day of each calendar month, together with any
monthly installments of estimated Tax Rent, Operating Expense Rent and Capital
Expense Rent (collectively "Total Monthly Rent"). Except as provided in Article
29, if the Commencement Date is not the first day of the calendar month or the
Termination Date is not the last day of the calendar month, then Total Monthly
Rent shall be prorated based upon a thirty (30) day month.

        3.2 All amounts due or relating to Tenant's occupancy under this Lease,
other than Total Monthly Rent, are due and payable within thirty (30) days of
receipt of Landlord's invoice for same. Such amounts include, without
limitation: annual reconciliations and retroactive charges of Tax Rent,
Operating Expense Rent or Capital Expense Rent; Orders for Extra Work; charges
for extra utilities and services; and Late Charges (collectively "Additional
Rent"). All amounts due under this Lease or relating to Tenant's occupancy are
deemed to be rent, receivable as such, and subject to all remedies of Landlord
for nonpayment of rent. Tenant's obligation to pay all amounts owing under this
Lease shall survive Tenant's relinquishment of possession to Landlord, or the
expiration or early termination of this Lease.

        3.3 Tenant agrees that Tenant's late payment of any sum due under this
Lease will cause Landlord to incur costs not contemplated hereunder, the exact
amount of which is impracticable or extremely difficult to fix. Therefore, if
all or any portion of any installment of Total Monthly Rent is not received by
Landlord by the fifth (5th) day of the month for which it is due, or if all or
any portion of any item of Additional Rent is not received by Landlord when due
pursuant to Article 3.2, then Tenant shall pay to Landlord a "Late Charge" of
ten percent (10%) of the overdue amount. Landlord and Tenant agree that the Late
Charge represents a fair and reasonable estimate of costs that Landlord will
incur by reason of any late payment by Tenant. Landlord's acceptance of a Late
Charge shall not constitute a waiver of Tenant's default with respect to the
overdue amount, or prevent Landlord from exercising any of the other rights and
remedies available to Landlord under this Lease or pursuant to law. The Late
Charge shall be in addition to, and not in lieu of, any interest which may
accrue pursuant to Article 35.11 of this Lease.

        3.4 All amounts due Landlord shall be paid by Tenant, without deduction
or offset, in lawful money of the United States of America, which shall be legal
tender at the time of payment. Payments shall be made at the office of Landlord
or to such other person or at such other place as Landlord notifies Tenant.
Landlord reserves the right to require that payments be made by certified check
or cash. No receipt by Landlord of an amount less than the full amount due will
be deemed to be other than a payment on account, and no endorsement or statement
on any check or any accompanying writing effect or evidence an accord and
satisfaction; and, Landlord may accept such check or payment without prejudice
to Landlord's right to recover the balance or pursue any other right or remedy
of Landlord.


ARTICLE 4 - TAX RENT

        4.1 For each successive calendar year of the Term after the Base Year
("Comparison Year"), Tenant shall pay to Landlord "Tax Rent", which shall be the
Proportional Share of the amount, if any, which the aggregate annual Property
Taxes for the Comparison Year exceeds the Property Taxes for the Base Year. Tax
Rent is payable in the manner set forth in Article 4.3. If this Lease terminates
on a day other than the last day of the Comparison Year, then Tax Rent for the
Comparison Year shall be prorated.

        4.2 "Property Taxes" is defined for purposes of this Lease as: all costs
and expenses which Landlord or Landlord's managing agent has incurred or will
incur for real and personal property taxes, or any other assessments upon
Landlord's legal or equitable interest in the Land, Building, Common Areas and
all or any related facilities and improvements (including, without limitation,
leasehold taxes or other taxes or assessments levied in lieu thereof or in
addition thereto), whether imposed by a government authority or agency, or by a
special assessment district; any taxes resulting from a reassessment of the
Building occasioned by any cause whatsoever, including, without limitation, any
reassessment resulting from a conveyance of Landlord's interest in the Land,
Building or Common Areas (whether or not such transfer occurs before or after
the Commencement Date), or by the determination by a court that any law,
regulation, statute, or constitutional provision purporting to limit tax
increases is invalid in whole or in part; any non-progressive tax on or measured
with respect to gross receipts from the rental of space in the Building; any
user fees or charges assessed for any government services which were provided
without cost prior to the imposition of Proposition 13; any assessment, tax,
fee, charge or levy for any transportation plan, fund or system within the
general geographic area of the Building; and, any expenses of Landlord in
contesting any of the foregoing or the assessed valuation of the Land, Building
or Common Areas. Notwithstanding the foregoing, the definition of "Property
Taxes" excludes any net income, franchise, capital stock, estate or inheritance
taxes.

<PAGE>   7

        4.3 As soon as practical after the beginning of each Comparison Year,
Landlord shall provide Tenant with Landlord's estimate of Property Taxes and Tax
Rent for the Comparison Year. During the Comparison Year, Tenant shall pay
Landlord's estimated Tax Rent in equal monthly installments on the first day of
each month. If the estimated Tax Rent for the Comparison Year is not determined
until after the beginning of the Comparison Year, then Tenant shall continue to
pay the monthly installments for the prior Comparison Year, if any, and shall
retroactively pay any underpayment of estimated Tax Rent payable for the period
from the beginning of the Comparison Year until the estimate was provided. As
soon as practical after the end of the Base Year, Landlord shall determine the
Property Taxes incurred in the Base Year and shall deliver to Tenant a written
statement setting forth the same. As soon as practical after the end of each
Comparison Year, Landlord shall determine the Property Taxes incurred in the
Comparison Year and shall deliver to Tenant a written statement setting forth
the same and a calculation of the Tax Rent allocable to Tenant. If Tenant has
underpaid its Tax Rent for the Comparison Year, then Tenant shall pay to
Landlord the full amount of such deficiency as Additional Rent. If Tenant has
overpaid its Tax Rent for the Comparison Year, then Landlord shall either credit
the overpayment toward Tenant's next installment(s) of Total Monthly Rent or, if
this Lease has terminated and Tenant is not in default, refund the overpayment
to Tenant within thirty (30) days of determination.

        4.4 If the value of the improvements in the Premises (regardless of
whether such improvements were installed or paid for by Landlord or Tenant, or
have been affixed to the real property to become a part thereof) exceed the
value of improvements generally prevailing in other leased premises in the
Building, then Tenant shall pay to Landlord as Additional Rent all Property
Taxes levied on such excess value. If the records of the County Assessor are
available and sufficiently detailed to serve as a basis for determining such
excess value, then such records shall be binding on Landlord and Tenant;
otherwise, the actual cost of construction shall be determinative.

        4.5 Tenant shall directly pay the taxing authority any tax levied
against the personal property or trade fixtures of Tenant in or about the
Premises. If Tenant fails to pay such tax before delinquency, then Landlord may
pay such tax on behalf of Tenant, and the amount paid shall constitute
Additional Rent due Landlord.

        4.6 The calculation and payment of Tax Rent is separate, distinct and
shall not be affected by the calculation and payment of either Basic Monthly
Rent, Operating Expense Rent or Capital Expense Rent. Any item of cost or
expense included as Property Taxes shall not be included as either Operating
Expenses or Capital Expenses.


ARTICLE 5 - OPERATING EXPENSE RENT [SEE ADDENDUM]

        5.1 For each Comparison Year, Tenant shall pay to Landlord "Operating
Expense Rent", which shall be the Proportional Share of the amount, if any, by
which the aggregate annual Operating Expenses for the Comparison Year exceeds

        5.4 As soon as practical after the beginning of each Comparison Year,
Landlord shall provide Tenant with Landlord's estimate of Operating Expenses and
Operating Expense Rent for the Comparison Year. During the Comparison Year,
Tenant shall pay Landlord's estimated Operating Expense Rent in equal monthly
installments on the first day of each month. If the estimated Operating Expense
Rent for the Comparison Year is not determined until after the beginning of the
Comparison Year, then Tenant shall continue to pay the monthly installments for
the prior Comparison Year, if any, and shall retroactively pay any underpayment
of estimated Operating Expense Rent payable for the period from the beginning of
the Comparison Year until the estimate was provided. As soon as practical after
the end of the Base Year, Landlord shall determine the Operating Expenses
incurred in the Base Year and shall deliver to Tenant a written statement
setting forth the same. As soon as practical after the end of each Comparison
Year, Landlord shall determine the Operating Expenses incurred in the Comparison
Year and shall deliver to Tenant a written statement setting forth the same and
a calculation of the Operating Expense Rent allocable to Tenant. If Tenant has
underpaid its Operating Expense Rent for the Comparison Year, then Tenant shall
pay to Landlord the full amount of such deficiency as Additional Rent. If Tenant
has overpaid its Operating Expense Rent for the Comparison Year, then Landlord
shall either credit the overpayment toward Tenant's next installment(s) of Total
Monthly Rent or, if this Lease has terminated and Tenant is not in default,
refund the overpayment to Tenant within thirty (30) days of determination.

        5.5 The calculation and payment of Operating Expense Rent is separate,
distinct and shall not be affected by the calculation and payment of either
Basic Monthly Rent, Tax Rent or Capital Expense Rent. Any item of cost or
expense included as Operating Expenses shall not be included as either Property
Taxes or Capital Expenses.


ARTICLE 6 - CAPITAL EXPENSE RENT [SEE ADDENDUM]

        6.1 During the Term, Tenant shall pay to Landlord "Capital Expense
Rent", which shall be the Proportional Share of any Capital Expenses incurred in
the calendar year, or which Landlord has in its discretion elected to amortize
in the calendar year. Capital Expense Rent is payable in the manner set forth in
Article 6.3. If this Lease commences or terminates on a day other than the first
or last day of a calendar year, Capital Expense Rent for the year shall be
prorated.

        6.2 "Capital Expenses" is defined for purposes of this Lease as all
costs and expenses which Landlord or Landlord's managing agent has incurred or
will incur (without offset for any revenue derived from any source whatsoever,
excepting the salvage value of any asset being removed or replaced to facilitate
the improvement, modification or addition to the Land, Building, Common Areas
and/or the machinery, equipment, and facilities related thereto) in the making
or installation of capital improvements, modifications or additions to the Land,
Building, Common Areas and/or the machinery, equipment and facilities related
thereto, either:

                (a)     Required by directive of an insurer or a government,
                        quasi-government or regulatory agency or authority
                        pursuant to either (i) a law or statute enacted after
                        the execution of this Lease, or (ii) an interpretation
                        of an existing law or statute, which interpretation is
                        promulgated after the execution of this Lease;

                (b)     Made with the intent and reasonable expectation of
                        reducing Operating Expenses; or

                (c)     Deemed reasonably necessary by Landlord to maintain the
                        quality, integrity and/or character of the Land,
                        Building, Common Areas and/or the machinery, equipment
                        and facilities related thereto.

        6.3 As soon as practical after the beginning of each calendar year (or
the Term, as the case may be), Landlord shall provide Tenant with Landlord's
estimate of the Capital Expenses and Capital Expense Rent for the calendar year.
During the calendar year, Tenant shall pay Landlord's estimated Capital Expense
Rent in equal monthly installments on the first day of each month. If the
estimated Capital Expense Rent for the calendar year is not determined until
after the beginning of the calendar year, then Tenant shall continue to pay the
monthly installments for the prior calendar year, if any, and shall
retroactively pay any underpayment of estimated Capital Expense Rent payable for
the period from the beginning of the calendar year until the estimate was
provided. As soon as practical after the end of each calendar year, Landlord
shall determine the Capital Expenses incurred, allocated or amortized in the
calendar year and shall deliver to Tenant a written statement setting forth the
same and a calculation of the Capital Expense Rent allocable to Tenant. If
Tenant has underpaid its Capital Expense Rent for the calendar year, then Tenant
shall pay to Landlord the full amount of such deficiency as Additional Rent. If
Tenant has overpaid its Capital Expense Rent for the calendar year, then
Landlord shall either credit the overpayment toward Tenant's next installment(s)
of Total Monthly Rent or, if this Lease has terminated and Tenant is not in
default, refund the overpayment to Tenant within thirty (30) days of
determination.

        6.4 The calculation and payment of Capital Expense Rent is separate,
distinct and shall not be affected by the calculation and payment of either
Basic Monthly Rent, Tax Rent or Operating Expense Rent. Any item of cost or
expense included as Capital Expenses shall not be included as either Property
Taxes or Operating Expenses.

        7.1 On or before execution of this Lease, Tenant shall deposit with
Landlord the Initial Security Deposit. The Initial Security Deposit and any
other sums deposited with Landlord pursuant to this Article (collectively
"Security Deposit") shall be held by Landlord as security for the faithful
performance by Tenant of all of the terms, covenants and conditions of this
Lease to be kept or performed by Tenant. From time to time during the Term,
Tenant shall deposit additional sums with Landlord so that the total Security
Deposit held by Landlord is not less than Tenant's then current Total Monthly

Deposit for the payment of rent or any other sum in default, or to compensate
Landlord for any loss or damage which Landlord has suffered or may suffer due to
Tenant's default. Tenant shall, upon demand, restore any Security Deposit so
used, applied or retained to the amount held by Landlord immediately prior

assignee of Tenant hereunder) any Security Deposit which has not been so used,
applied or retained. Notwithstanding the foregoing, Landlord may retain all or a
portion of the Security Deposit to secure any remaining obligations of Tenant
hereunder (including, without limitation, Tenant's obligations pursuant to
Articles 4, 5 and 6, which Tenant acknowledges cannot be fully ascertained until
as soon as practical after the end of the calendar year). Tenant waives
application of the provisions of California Civil Code section 1950.7 in respect
hereto.

        7.4 If Landlord transfers, assigns or conveys its interest in the
Premises, then Landlord shall be discharged from any liability for the return of
Tenant's Security Deposit, provided Landlord transfers all Security Deposit
which has not been used, applied or retained to Landlord's successor in
interest.

Lease. Tenant shall use the Premises solely for the Permitted Use and shall not
use or permit the Premises to be used for any other purpose without the prior

Tenant shall not be deemed a waiver of Landlord's right to withhold its consent
to any subsequent proposed change of use.

certificates, rules, directives, orders and regulations of any public authority

comply with this Lease.

        8.4 Tenant shall not do or permit to be done anything which will
constitute a nuisance, or obstruct, injure, annoy or interfere with the rights

respective property or business, and Tenant shall not be entitled to any
abatement or reduction of rent as a result of Landlord's failure to provide

        11.2 Landlord shall repair and maintain all parts of the Land, Building
or Common Areas which do not constitute the Leasehold Improvements.

Landlord (as Additional Rent) the reasonable cost for such maintenance and
repairs. If Landlord reasonably believes damage to the Land, Building or Common
Areas is being caused by Tenant, its agents, servants, employees, licensees or
invitees (whether an isolated incident or a continuous course of conduct, and
whether by an individual or group), then upon receipt of written notice from
Landlord, Tenant shall take reasonable action to prevent any additional or
future damage and Tenant's failure to do so shall be a material breach of this
Lease.


ARTICLE 12 - CONDITION OF PREMISES

        12.1 Subject to any provisions of this Lease concerning the making of
Leasehold Improvements in the Premises (if any), by taking possession of the

warranty concerning the Land, Building, Common Areas or Premises, or the
suitability of either for the conduct of Tenant's business.

        12.2 Upon the expiration of the Term or earlier termination of this
Lease, Tenant shall relinquish possession of the Premises to Landlord inclusive
of all Leasehold Improvements and Alterations (unless Landlord has either

received, ordinary wear and tear excepted, free of all trash and rubbish, and in
broom clean condition. Landlord may dispose of any personal property remaining
in the Premises in accordance with California Civil Code section 1980, et seq.,
and shall be entitled to recover all costs and expenses provided therein,

advance of same, Landlord shall have the right to enter the Premises to inspect
the Premises, show the Premises to prospective purchasers or tenants, and make
alterations, improvements or repairs (including construction required by the
character of the work). No advance notice shall be required for Landlord to
supply janitorial services or to post legal notices.

        13.2 Notwithstanding the provisions of Article 13.1, Landlord shall be
entitled to enter the Premises without advising Tenant in advance or making the
required effort to minimize interference with Tenant's business when Tenant is
in default of this Lease, or in an "Emergency" (which shall be any circumstance

other tenants, occupants or the general public, or result in a liability or loss
to Landlord).

        13.3 Landlord shall at all times have a key with which to unlock all of

locks, repair any damage and restore the Premises, and charge Tenant as
Additional Rent all expenses incurred in accomplishing the foregoing.

be no abatement of rent and no liability of Landlord by reason of any injury to,
or interference with Tenant's business arising from any entry performed by
Landlord in a good faith attempt to comply with the terms of this Article. Any
such good faith entry shall not constitute an eviction, or a forcible or
unlawful entry or detainer of the Premises.

ARTICLE 14 - ALTERATIONS & RENOVATIONS

        14.1 All alterations, additions, decorations or improvements made by or
on behalf of Tenant in or to the Premises except Tenant Improvements

give Landlord ten (10) days' prior written notice of Tenant's desire to make
Alterations. Landlord may impose any reasonable condition upon issuing
Landlord's consent (including, without limitation: requiring Tenant to remove
Alterations at the end of the Term and restore the Premises to the condition
prior to Alterations having been made [reasonable wear and tear excepted];
obtaining the consent of any mortgagee, encumbrancer, lender or ground lessee;

products liability, completed operations, worker's compensation and public
liability insurance in amounts satisfactory to Landlord, naming Landlord as an
additional insured. Alterations shall be performed at the times and in the
manner specified by Landlord, and shall not interfere with access or use of the
Common Areas or other premises. Alterations shall be performed in full
compliance with all laws, rules and/or directives of any government or
regulatory agency or authority; and, if any such government or regulatory agency
or authority requires any improvements, modifications, additions or alterations
to any part of the Base Building, as a result of the Alterations, then the same
shall be made by Tenant at Tenant's sole cost and expense.

        14.3 All permanent improvements to the Premises, Leasehold Improvements
and Alterations (including, without limitation, floor and wall coverings,
blinds, drapes, cabinets, shelving, doors, locks, paneling and the like) which
Landlord has not required Tenant to remove at the end of the Term shall become
the property of Landlord upon the termination of this Lease and shall be
relinquished with the Premises.

        14.4 Landlord may require Tenant to immediately remove any Alterations
not made in accordance with this Article, and restore the Premises to the
condition immediately prior to the Alterations' having been made (reasonable
wear and tear excepted). If Tenant either fails to immediately remove
Alterations not made in accordance with this Article after Landlord's demand, or
fails at the end of the Term to remove Alterations which Landlord required to be
removed at the end of the Term as a condition of issuing Landlord's consent to
the making of such Alterations, then Landlord may perform such removal and
restore the Premises, at Tenant's sole cost and expense, to the condition
immediately prior to the Alterations having been made (reasonable wear and tear
excepted).

        14.5 All Alterations, removal of Alterations and restoration of the
Premises which Landlord is reasonably required to perform or supervise are
subject to Landlord's charge, as Additional Rent, for all costs and expenses of
such performance and supervision (including, without limitation, review of plans
or work by Landlord's architect, engineer or other consultant), plus a
supervision fee payable to Landlord in the amount of fifteen percent (15%) of
the cost of such work.

        14.6 During the Term, Landlord may renovate, improve, alter, or modify
the Building, Common Areas, Premises or Leasehold Improvements ("Renovations"),
although nothing herein shall be construed to obligate Landlord to make such
Renovations, except as expressly set forth in this Lease. In connection with any
Renovations, Landlord may erect scaffolding or other necessary structures, limit
or eliminate access to portions of the Building, Common Areas or Premises, or
perform work which may create noise, dust or debris. Tenant hereby agrees that,
except as expressly provided in this Lease (in particular, Article 22), such
Renovations shall in no way constitute a constructive eviction of Tenant nor
entitle Tenant to any abatement of rent, and Landlord shall have no
responsibility or for any reason be liable to Tenant for any direct or indirect
injury to or interference with Tenant's business arising from the Renovations,
nor shall Tenant be entitled to any compensation or damages from Landlord for
loss of the use of the whole or any part of the Premises or of Tenant's personal
property or improvements resulting from the Renovations, or for any
inconvenience or annoyance occasioned by the Renovations.

                        extended coverage endorsement perils, leakage from fire

                        replacement cost of the Building, Common Areas and all
                        fixed improvements therein, except those fixtures,
                        furnishings, Leasehold Improvements, equipment and other
                        property which Tenant is required to insure pursuant to

conditions as Landlord prudently determines to be commercially reasonable and
sufficient, provided such terms are generally available at a commercially
reasonable price in the area in which the Building is located.

                        replacement cost of the Leasehold Improvements and
                        Tenant's fixtures, furnishings, equipment, inventory,
                        stock-in-trade;

                (c)     Insurance covering those items set forth in subparagraph
                        (b) against loss or damage due to earthquake (or change
                        in condition);

                (d)     Insurance for loss of income or insurable gross profits
                        covering such perils set forth in subparagraphs (b) and

                        compensation insurance).

Notwithstanding the foregoing, Tenant may elect to self-insure the coverage
required pursuant to subparagraphs (c) and (d), above; however, Tenant's
election to self-insure such coverage shall not impair the waivers of
subrogation and recovery set forth in Article 18.4, below. Notwithstanding the
above, Landlord may reasonably and prudently change the insurance requirements
set forth herein (including, without limitation, requiring additional coverage
or types of insurance), provided that insurance to meet such changed
requirements is generally available at a commercially reasonable price in the
area in which the Building is located.

        18.3 On or before Tenant's use or occupancy of the Premises for any
purpose and from time to time during the Term, Tenant shall provide Landlord
with copies of such policies, certificates or other proof necessary for Landlord
to verify that the required insurance coverage has been obtained, is in full
force and effect and that the premiums have been paid thereon. All policies
shall contain an undertaking by the insurer to notify Landlord (and any
mortgagees or ground lessors designated by Landlord) in writing not less than
thirty (30) days prior to any material change, reduction, cancellation or other
termination of coverage required hereunder. Replacement policies or certificates
shall be furnished to Landlord not less than thirty (30) days prior to the
expiration of any such policy or policies. Landlord's failure to request
evidence of coverage shall not constitute a waiver of any of Landlord's rights
hereunder or Tenant's obligation to so insure.

        18.4 Insurance to be provided and maintained by either party pursuant to
Article 18.1, subparagraphs (b), (c) and (d) (and [e], to the extent of
earthquake and other change of condition insurance), and Article 18.2,
subparagraphs (b), (c) and (d) shall include a clause or endorsement whereby the
insurer waives its right of subrogation against the other party; and Landlord
and Tenant each waive any rights of recovery against the other for injury or
loss due to hazards required to be covered by insurance which is required to
contain such a waiver of subrogation, to the extent of the injury or loss
required to be covered thereby.


ARTICLE 19 - INDEMNIFICATION

        19.1 Subject to the waivers of subrogation and liability set forth in
Article 18.4, Tenant shall indemnify and hold Landlord harmless from and against

attorneys' fees, whether for personal injury, theft, property damage or
otherwise, due to or arising from:

                (a)     Any accident, act or omission (whether or not related to
                        Tenant's use of the Premises or conduct of business
                        therein) occurring in, or originating or emanating from
                        the Premises, except to the extent caused by the
                        negligence or willful misconduct, or breach or
                        non-performance described in Article 19.2, subparagraph
                        (b) or (c);

                (b)     The negligence or willful misconduct of Tenant, its
                        servants, employees, agents, contractors, invitees,
                        concessionaires or licensees, or those over whom Tenant
                        would normally be expected to exercise control, whether
                        in or about the Land, Building, Common Areas, Premises,
                        or parking facility; or

                (c)     Tenant's breach or non-performance of any provision of
                        this Lease.

expense by counsel reasonably satisfactory to Landlord.

        19.2 Subject to the waivers of subrogation and liability set forth in
Article 18.4, Landlord shall indemnify and hold Tenant harmless from and against
any and all liability, loss, claims, demands, damages or expenses, including
attorneys' fees, whether for personal injury, theft, property damage or
otherwise, due to or arising from:

                (a)     Any accident, act or omission in or about the Land,
                        Building, and Common Areas, except to the extent caused
                        by any accident, act or omission, negligence or willful
                        misconduct, or breach or non-performance described in
                        Article 19.1, subparagraphs (a) through (c);

                (b)     The negligence or willful misconduct of Landlord, its

                        whether in or about the Land, Building, Common Areas,
                        Premises, or parking facility; or

                (c)     Landlord's breach or non-performance of any provision of
                        this Lease.

If any action or proceeding is brought against Tenant by reason of any such
claim, then Landlord, upon notice from Tenant, shall defend the same at
Landlord's expense by counsel reasonably satisfactory to Tenant.


ARTICLE 20 - DAMAGE OR DESTRUCTION

        20.1 If the Leasehold Improvements are damaged or destroyed by any
cause, then Tenant shall, at Tenant's sole cost and expense, promptly repair,
replace and restore the Leasehold Improvements to at least the condition
existing prior to the damage (reasonable wear and tear excepted) during which
time this Lease shall remain in full force and effect, subject to Article 22.

        20.2 If any portion of the Land, Building or Common Areas (excepting the
Leasehold Improvements) reasonably necessary for Tenant's access, use or
occupancy of the Premises is damaged or destroyed by any cause, then:

                (a)     Within thirty (30) days after the event of damage or
                        destruction, Landlord shall assess the damage, determine
                        how long repairs will take and promptly thereafter
                        provide Tenant with written notice of the same (however,
                        if more than thirty (30) days are reasonably required to
                        so assess the damage and determine the length of time
                        for repair, then Landlord shall not be in default
                        hereunder if Landlord commences such assessment and
                        determinations within said thirty (30) day period and
                        otherwise diligently proceeds with such assessment and
                        determinations, and promptly provides Tenant with
                        written notice of the same).

                (b)     If the event such damage or destruction either:

                        (i)     Is uninsured by Landlord (and not required to be
                                insured by Landlord pursuant to Article 18.1),
                                or

                        (ii)    Cannot, in Landlord's reasonable opinion, be
                                repaired within one hundred eighty (180) days
                                after the occurrence of such damage or
                                destruction,

                        then Landlord may terminate this Lease upon at least
                        thirty (30) days' prior written notice to Tenant, the
                        Lease to remain in full force and effect through the
                        specified termination date, subject to Article 22;
                        otherwise, Landlord shall proceed with repairs during
                        which time this Lease shall remain in full force and
                        effect, subject to Articles 20.3 and 22.

        20.3 Notwithstanding anything to the contrary contained herein, Landlord
shall have no obligation to repair or restore damage or destruction described
under Article 20.2 when it occurs during the last twelve (12) months of the
Term; however, if Landlord so elects not to repair or restore and the damage or
destruction either:

                (a)     Substantially adversely affects Tenant's use of all or a
                        material part of the Premises, or

                (b)     Prevents Tenant's reasonable access to the Premises,

then, in addition to Tenant's rights under Article 22, Tenant shall have the
right to terminate this Lease upon at least thirty (30) days' prior written
notice to Landlord, which notice shall be given within fifteen (15) days after
receipt of Landlord's election not to repair or restore.

        20.4 If the damage or destruction is insured (or required to be insured
or self-insured) by Tenant pursuant to Article 18.2 and either Landlord or
Tenant elect to terminate this Lease pursuant to Article 20.2(b), 20.3 or 22,
then Tenant shall assign to Landlord its right to receive the benefits under
such insurance for the repair and restoration of the Leasehold Improvements, and
directly pay Landlord any deductible under such policy (and any other uninsured
amounts). If the damage or destruction is uninsured (and not required to be
insured or self-insured) by Tenant pursuant to Article 18.2 and either Landlord
or Tenant elect to terminate this Lease pursuant to Article 20.2(b), 20.3 or 22,
then Tenant shall pay to Landlord the lesser of:



                                 Page 12 of 22
<PAGE>   16

                (a)     The cost of repairing the damage or destruction of the
                        Leasehold Improvements; or

                (b)     The unamortized value of the Leasehold Improvements on
                        the effective date of termination (assuming the value of
                        the Leasehold Improvements in the Premises at the
                        inception of the Lease was amortized over the term, with
                        interest at the rate set forth in Article 35.11, in
                        equal monthly installments).

        20.5 Tenant hereby waives the application of California Civil Code
sections 1932(2) and 1933(4), to the extent contrary to the provisions of
Articles 20 and 22 of this Lease.


ARTICLE 21 - EMINENT DOMAIN

        21.1 If all or any portion of the Land, Building, Common Areas or
Premises is taken for any public or quasi-public purpose by any lawful power or
authority by exercise of the right of appropriation, condemnation or eminent
domain (or sold in lieu of such taking), then:

                (a)     If such taking or sale substantially interferes with
                        Tenant's use and occupancy of the Premises, then this
                        Lease shall terminate on the date of surrender or sale
                        to said authority; or

                (b)     If such taking or sale does not substantially interfere
                        with Tenant's use and occupancy of the Premises, then
                        Landlord may either terminate this Lease or restore the
                        Premises to substantially the same condition prior to
                        such partial taking, and Tenant's Total Monthly Rent
                        shall be abated with respect to that portion of the
                        Premises rendered unusable for the conduct of Tenant's
                        business therein as a result of the taking or sale, for
                        the period of time that such portion is so rendered
                        unusable.

        21.2 Tenant shall not assert any claim for the taking of any interest in
this Lease, the Land, Building, Common Areas or Premises and Landlord shall be
entitled to receive the entire amount of any award without deduction or offset
for any estate or interest of Tenant; however, Tenant shall be entitled to bring
a separate action for relocation expenses, and damages to Tenant's personal
property, trade fixtures and goodwill. Tenant hereby waives the application of
California Code of Civil Procedure section 1265.130.


ARTICLE 22 - INTERRUPTION OF USE

        22.1 If either use of the Premises is substantially adversely affected
or reasonable access to the Premises is prevented as a result of:

                (a)     An event of damage or destruction as described in
                        Articles 20.1 and 20.2, excepting only damage or
                        destruction caused by the gross negligence or willful
                        misconduct of Tenant;

                (b)     A Taking (as defined in Article 21);

                (c)     The failure of Landlord to repair or maintain the
                        Building or Common Areas to the extent required pursuant
                        to Article 11;

                (d)     The failure of Landlord to provide utilities or services
                        which Landlord is obligated to provide pursuant to
                        Article 9 (provided that such failure is not caused by
                        the public utility providing service to the Building);
                        or

                (e)     Renovations (as defined in Article 14);

then, such event shall constitute an "Interruption" hereunder.

        22.2 If an Interruption occurs and continues for a period of at least
five (5) consecutive business days, then Tenant's Total Monthly Rent shall be
abated from the sixth (6th) business day until use of the Premises is no longer
so substantially and adversely affected and reasonable access to the Premises
exists, provided, however, that:

                (a)     Any abatement of rent hereunder shall be prorated to
                        reflect that portion of the Premises that is actually
                        rendered unusable for the conduct of business therein
                        for the period of time such portion is so rendered
                        unusable, and shall not be afforded Tenant to the extent
                        that Tenant uses the Premises for the conduct of
                        business therein;



                                 Page 13 of 22
<PAGE>   17

                (b)     No abatement of rent hereunder shall be afforded Tenant
                        for any period of time which Tenant has not complied
                        with its obligations under Article 20.1, provided that
                        abatement of rent is solely available under the
                        provisions of Article 20.1; and

                (c)     Notwithstanding the Permitted Use, no abatement of rent
                        shall result from any inability of Tenant to use the
                        Premises because of Tenant's unique use of the Premises
                        as other than general administrative offices.

Such period to which Tenant shall be entitled to abatement of Total Monthly Rent
hereunder shall constitute the "Interruption Period." Landlord shall advise
Tenant of Landlord's reasonable estimate of the Interruption Period (based upon
taking commercially reasonable action in response to such Interruption), as soon
as reasonably practicable or as otherwise required under this Lease.

        22.3 In addition to Tenant's rights under Article 22.2, if the
Interruption Period is reasonably estimated by Landlord to continue for a period
exceeding one hundred eighty (180) days, then Tenant may, within fifteen (15)
days after receipt of Landlord's estimate, elect to terminate the Lease upon
thirty (30) days' prior written notice. Notwithstanding the foregoing, this
Lease shall not be terminated if Landlord elects to take such additional action
not otherwise required under this Lease within said thirty (30) day period which
will result in the restoration of Tenant's reasonable access to, and use of the
Premises within said one hundred eighty (180) day period. If Tenant does not
elect to terminate this Lease within such fifteen (15) day period, Landlord
shall not be liable to Tenant and Tenant will not be entitled to terminate this
Lease if such repairs and restoration are not in fact completed within the
estimated Interruption Period, provided that the Interruption Period was
reasonably estimated by Landlord and Landlord diligently commenced and pursues
such repairs and restoration to completion.


ARTICLE 23 - SUBORDINATION, NONDISTURBANCE AND ATTORNMENT

        23.1 Subject to the provisions of Article 23.2, this Lease shall be
subject and subordinate to all present and future ground or underlying leases of
the Building or Project and to the lien of any mortgage, trust deed or other
encumbrances now or hereafter in force against the Building or Project or any
part thereof, and to any and all renewals, modifications, consolidations,
replacements, substitutions and extensions thereof, as if the mortgage, trust
deed or other encumbrance and all of its renewals, modifications,
consolidations, replacements, substitutions and extensions had been executed,
delivered and recorded prior to execution of this Lease.

        23.2 In the event of the termination of any ground lease or underlying
lease, or the foreclosure of any mortgage, trust deed or other encumbrance, or
upon a transfer or conveyance in lieu of such foreclosure, then so long as the
Lease is then in full force and effect and Tenant is not in default under any of
the terms, covenants or conditions of the Lease, Tenant agrees to attorn to and
accept any such successor owner as lessor under the Lease and to be bound by and
perform all of the obligations imposed by the Lease, and successor owner will
not disturb the possession of Tenant and will be bound by and perform all of the
obligations of Landlord, except that successor owner will not be liable for: any
act, omission or default of Landlord, or be subject to any claims, offsets,
defenses, credits or deductions which Tenant might have against Landlord; any
rent, additional rent or other sum Tenant paid to Landlord more than one (1)
month in advance, or by any security deposit, cleaning deposit or other prepaid
charge Tenant paid to Landlord and not held by or paid over to successor owner;
any conflict between the provisions of the Lease and any other lease affecting
the Building or Project; or, constructing or completing any improvements to the
Premises, Building or Project required under this Lease, whether prior to or
during the Term, or in connection with any renewal, extension or expansion
hereof.

        23.3 Tenant shall, within five (5) business days after receipt of
Landlord's written request, execute such further instruments or assurances as
Landlord may reasonably deem necessary to evidence or confirm the subordination,
nondisturbance and attornment pursuant to this Article. Tenant waives the
provisions of any current or future statute, rule or law contrary to the
provisions of this Article which may give Tenant any right or election to
terminate or otherwise adversely affect this Lease and the obligations of the
Tenant hereunder in the event of any the foreclosure of any mortgage, trust deed
or other encumbrance, or upon a transfer or conveyance in lieu of such
foreclosure.


ARTICLE 24 - OFFSET STATEMENT

        24.1 Upon Landlord's request, Tenant shall execute, acknowledge and
deliver to Landlord a statement in writing setting forth Tenant's certification
of the following: that this Lease is unmodified (or, if modified, the nature of
such modification) and is in full force and effect; the extent to which rental
or other charges have been prepaid; and that Landlord, to Tenant's knowledge,
has not failed to cure any default of Landlord of this Lease (or specifying such
uncured defaults, if any are claimed). Tenant's failure or refusal to execute
and deliver such a statement within ten (10) days after receipt of Landlord's
request shall be conclusive upon Tenant that: this Lease is in full force and
effect, without modification (except as may be represented by Landlord); except
as provided in this Lease, not more than one month of rent has been paid in
advance, and not more than one month of security deposit is being held by
Landlord; and, there are no uncured defaults of Landlord. Tenant acknowledges
that such statement may be relied upon by a prospective purchaser or
encumbrancer of all or any portion of the Land, Building or Premises.

ARTICLE 25 - BUILDING PLANNING [DELETED]


ARTICLE 26 - ASSIGNMENT AND SUBLETTING

        26.1 Unless Tenant has obtained the prior written consent of Landlord
(which may only be denied by Landlord upon a commercially reasonable ground),
Tenant shall not pledge, sell, transfer, hypothecate, encumber or assign this
Lease or Tenant's interest therein, sublet all or any part of the Premises, or
permit occupancy or the conduct of business in any or all of the Premises by
anyone other than Tenant. Any assignment, sublease, sale, mortgage, pledge,
encumbrance or transfer by Tenant or such other party made in contravention of
this Article shall be void and of no force or effect.

        26.2 If Tenant proposes to assign this Lease or to sublet all or any
portion of the Premises, then Tenant shall give Landlord written notice of
Tenant's intent to so assign or sublet at least thirty (30) days' prior to the
proposed effective date of the assignment or sublease. The notice shall include,
with respect to each proposed assignee or subtenant: name and address; terms and
conditions of the proposed assignment or sublease; a detailed statement of facts
about the nature of the proposed use of the Premises and the proposed assignee's
or subtenant's business experience; a balance sheet showing financial condition
as of a date within ninety (90) days prior to the date of the notice; statements
of income, profit and loss for the last two (2) complete fiscal years; bank and
credit references; and, such other and further information as Landlord may
reasonably require.

        26.3 If Tenant proposes to assign this Lease or sublet substantially all
of the Premises for substantially all of the remaining Term of this Lease to a
party other than Tenant's Affiliate, then during the thirty (30) day period
immediately following Landlord's receipt of Tenant's notice pursuant to Article
26.1, Landlord shall have the right to terminate this Lease in its entirety,
after which Tenant shall have no further obligation to Landlord under this
Lease, except for matters occurring or obligations arising prior to the
effective date of termination. Landlord shall exercise Landlord's right to
terminate by giving Tenant written notice of same, such notice to specify the
effective date of termination (which shall be the later of either: the effective
date of the assignment or sublease proposed by Tenant; or a date specified by
Landlord which is no less than thirty (30) days, but no more than sixty (60)
days after Tenant's receipt of Landlord's notice to terminate). Landlord
reserves the right, after electing to terminate as provided herein, to acquire
the Premises for its own use, or enter into a Lease with another tenant or the
proposed assignee or subtenant on such terms and conditions as in Landlord's
sole discretion, without Tenant being entitled to any portion of the profit
which Landlord may realize as a result of such termination and reletting.

        26.4 If Landlord does not exercise its termination right set forth in
Article 26.3, then Landlord shall, within such thirty (30) day period following
receipt of Tenant's notice pursuant to Article 26.2, notify Tenant that Landlord
either grants or denies its consent for Tenant to proceed to assign or sublet on
the terms and conditions contained in Tenant's notice. Landlord's failure to
timely exercise its termination rights pursuant to Article 26.3 or timely deny
consent shall be deemed approval to assign or sublet on the terms and conditions
contained in Tenant's notice, but only to the extent that the represented terms
and conditions do not conflict with the terms and conditions of this Lease.
Landlord may deny consent to assign or sublet upon any commercially reasonable
ground, including, but not limited to, the following:

                (a)     The proposed assignee or subtenant is an existing Tenant
                        of Landlord in the Building or any other Building owned
                        or managed by Landlord in the Los Angeles/Orange County
                        Metropolitan Area, or has negotiated with Landlord
                        concerning the leasing of Premises from Landlord within
                        the prior one hundred twenty (120) days;

                (b)     The financial strength of the proposed assignee or
                        subtenant, in Landlord's opinion, is insufficient to
                        enable it to meet its proposed financial obligations;

                (c)     If Tenant is to relocate, the financial strength of
                        Tenant after the proposed assignment or sublease and
                        relocation would be insufficient to enable it to meet
                        its financial obligations under this Lease;

                (d)     The proposed use, or reputation or character of the
                        proposed assignee or subtenant is not in keeping with
                        the nature of the Building or may adversely affect the
                        operation, insurability, or reputation of the Building;

                (e)     The proposed use of the Premises is materially different
                        than the Permitted Use; or

                (f)     The proposed use of the Premises conflicts with any
                        other existing agreements between Landlord and other
                        tenants concerning the Land, Building, Common Areas or
                        Premises;

                (g)     {Deleted}.

If Landlord denies consent to assign or sublet, Tenant waives the right to
terminate this Lease pursuant to California Civil Code section 1995.310(b).

        26.5 Fifty percent (50%) of any consideration, including rents, received
by or on behalf of Tenant from such assignment or sublease in excess of Total
Monthly Rent shall be payable to Landlord upon receipt by Tenant as Additional
Rent. Notwithstanding the foregoing, Tenant shall be entitled to recapture from
any such excess consideration Tenant's costs and expenses for brokerage
commissions, advertising to sublet or assign and shared services (including,
without limitation, expenses of a shared receptionist, library, telephone
system, photocopier, or other similar office expense).

        26.6 Any allowances, concessions, rights to acquire additional Premises,
rights to extend or renew, options, parking discounts or any other similar
concessions or consideration set forth in this Lease and any addenda or
amendments thereto are expressly understood to be solely for the benefit of the
original Tenant and shall be null, void and of no force or effect as of the
effective date of any assignment or subletting; however, this shall not be
deemed to retroactively nullify or void any allowances, concessions, rights or
options actually disbursed, made or exercised prior to such effective date.

        26.7 Any advertisement, publicity or other public solicitation of any
assignment or subletting of the Premises shall require Landlord's prior written
approval.

        26.8 Any permitted assignment or subletting of the Premises shall not
act to release Tenant or any subsequent assignor or sublessor from any liability
under this Lease, and Tenant shall cause any assignee to execute an agreement
with Landlord upon a form furnished by Landlord binding the assignee or
sublessee to all the terms of this Lease without relieving Tenant of any
liability hereunder. As security for Tenant's obligations under this Lease,
Tenant assigns to Landlord the right to collect all rent resulting from any
assignment or sublease of the Premises in the event of Tenant's default; and
Landlord (as assignee and attorney-in-fact for Tenant, or as a receiver for
Tenant appointed on Landlord's application, may upon written notice to Tenant
and subtenant or assignee, thereafter collect and apply such rent toward the
satisfaction of Tenant's obligations under this Lease. Tenant shall pay a
reasonable processing fee to Landlord for each assignment or sublease submitted
to Landlord, not to exceed Five Hundred Dollars ($500.00).

        26.9 Unless Tenant is a corporation whose stock is traded through a
recognized United States exchange, any of the following shall be deemed to be a
voluntary assignment requiring Landlord's consent: a change in business status
or organization, dissolution, merger, consolidation or other reorganization of
Tenant (either voluntarily or pursuant to any provision of the Bankruptcy Act);
the sale or other transfer of a controlling share of the voting capital stock of
Tenant; or, the sale of fifty-one percent (51%) or more of the interests of
Tenant. However, if Tenant is a corporation whose stock is traded through a
recognized United States exchange, then, provided Tenant is not in default
hereunder, Tenant may assign this Lease or sublet the Premises to a corporation
into or with which Tenant is merged or consolidated, or to which all or
substantially all of Tenant's assets are transferred, or to any corporation or
other entity which controls or is controlled by the Tenant or is under common
control or affiliated with the Tenant. Tenant shall notify Landlord of any such
assignment or sublease in accordance with Article 34 of this Lease and
concurrently provide Landlord with the same financial information as required in
Article 26.2 with respect to any proposed assignee or sublessee.

        26.10 Notwithstanding anything to the contrary contained in Article 26
of this Lease, and provided Tenant is not in default of this Lease with all
applicable notices having been given and cure periods having expired, Tenant may
assign this Lease or sublet the Premises without Landlord's prior consent to
"Tenant's Affiliate" defined as: to a corporation into or with which Tenant is
merged or consolidated; to a corporation into which all or substantially all of
Tenant's assets are transferred; to any corporation or other entity which
controls or is controlled by Tenant; or, to a corporation controlled by Tenant's
parent corporation to the same extent as Tenant is controlled by such parent
corporation. Tenant shall, nevertheless, notify Landlord of any such assignment
or sublease in accordance with Article 34 of this Lease and provide Landlord
with the same information regarding the assignee or transferee required by
Article 26.2, herein.


ARTICLE 27 - BANKRUPTCY AND INVOLUNTARY ASSIGNMENT

        27.1 Any of the following acts or occurrences with respect to either
Tenant or any guarantor of this Lease shall constitute an involuntary
assignment: filing a petition under Chapter 7, 10, 11 or any other provision of
the Bankruptcy Act now or hereafter in effect; making an assignment for the
benefit of creditors; being adjudicated bankrupt in involuntary bankruptcy
proceedings, unless the judgment is vacated within sixty (60) days from entry;
becoming insolvent (reflected by either a written admission of inability to meet
current obligations, actual inability to meet current obligations, or
liabilities exceeding assets); appointment of a receiver or trustee for any
property, unless the appointment is set aside or vacated within sixty (60) days
after entry; attachment or execution upon any property (including, without
limitation, this Lease) unless the attachment or execution is removed within
sixty (60) days after levy; or transfer or assignment of this Lease by operation
of law (including, without limitation, transfer by will or intestacy).

        27.2 An involuntary assignment shall constitute a default by Tenant and
Landlord shall have the right to terminate this Lease. This Lease shall not be
treated as an asset of Tenant and neither Tenant nor any person claiming through
or under Tenant (or by virtue of any statute or order of any court) shall be
entitled to possession of the Premises, which shall be forthwith surrendered to
Landlord. Landlord shall be entitled to recover damages at least in the amounts
set forth in Article 31 of this Lease; however, nothing herein shall limit or
prejudice the right of Landlord to seek any other damages allowed by any
applicable statute or rule of law.

ARTICLE 28 - FINANCIAL STATEMENTS

        28.1 If Tenant is in default of this Lease, or Landlord is proposing to
convey, finance or refinance Landlord's interest in the Land, Building or Common
Areas, then Landlord shall have the right to require Tenant to furnish Landlord
with financial statements prepared by a Certified Public Accountant according to
generally recognized accounting principles showing Tenant's financial condition
as of a date not more than ninety (90) days prior to submission to Landlord.


ARTICLE 29 - HOLDING OVER

        29.1 Tenant shall not hold over after the expiration of the Term or
earlier termination of this Lease without the prior written consent of Landlord
(which shall not be subject to Article 35.1). Tenant agrees that Tenant's
failure to surrender possession of the Premises at the end of the Term can and
will cause actual damage to Landlord which is impracticable or extremely
difficult to ascertain (including, without limitation, lost opportunities to
lease the Premises, increase in the cost of improvements, lost rent and
liability for Landlord's inability to deliver timely possession of the Premises
to another tenant). Therefore, if Tenant holds over after the Term without the
prior written consent of Landlord, then Tenant shall become a Tenant at
sufferance only and shall continue to perform each and every term, condition and
covenant of this Lease during any such period of holding over; except that, in
lieu of damages to which Landlord may be entitled hereunder, Landlord may elect
to have Tenant pay Landlord liquidated damages in an amount equal to one hundred
fifty percent (150%) of the Total Monthly Rent payable by Tenant to Landlord in
the last complete month of the Term, for each month or portion thereof which
Tenant so holds over.

        29.2 {Deleted}.

        29.3 The foregoing provisions of this Article are in addition to any
other rights of Landlord hereunder, or as otherwise provided by law, including,
without limitation, the right to bring an action for unlawful detainer.
Landlord's acceptance of rent after expiration or earlier termination of this
Lease, or during any such period of holding over shall not be construed as a
renewal or extension of this Lease. Notwithstanding anything to the contrary
contained in this Lease, Tenant shall not be entitled to any parking discounts
or specified modes of parking during any such period of holding over.


ARTICLE 30 - DEFAULTS

        30.1 The occurrence of any one or more of the following events shall
constitute a default of this Lease by Tenant:

                (a)     Tenant's failure to pay when due any Basic Monthly Rent,
                        Tax Rent, Operating Expense Rent, Capital Expense Rent,
                        Additional Rent or any other payment due Landlord under
                        this Lease where such failure continues for a period of
                        five (5) days after receipt of written notice from
                        Landlord setting forth such failure;

                (b)     Any default set forth in Article 27 of this Lease; or

                (c)     Tenant's failure to observe or perform any express or
                        implied covenant or provision of this Lease, other than
                        those specified in subparagraphs (a) and (b), above,
                        within ten (10) days after receipt of notice from
                        Landlord; however, if more than ten (10) days are
                        reasonably required to so observe or perform, then
                        Tenant shall not be in default so long as Tenant
                        commences observance or performance within said ten (10)
                        day period and diligently prosecutes same to completion.

        30.2 Any notice of default Landlord is required to give Tenant hereunder
and any notice Landlord may be required to give pursuant to California Code of
Civil Procedure section 1161, et seq. (or any similar law now or hereafter in
effect) may be satisfied by a single notice inclusive of the requirements of
both this Article and statutory law.

        30.3 Landlord shall be in default of this Lease if Landlord fails to
observe or perform any material covenant or provision of this Lease that
Landlord is required to so observe or perform within fifteen (15) days after
receipt of written notice from Tenant to Landlord specifying the nature of such
failure; however, if more than fifteen (15) days are reasonably required to so
observe or perform, then Landlord shall not be in default so long as Landlord
commences observance or performance within said fifteen (15) day period and
diligently prosecutes same to completion. In no event shall Tenant have the
right to terminate this Lease as a result of Landlord's default, and Tenant's
remedies shall be limited to damages and/or an injunction. Tenant acknowledges
that the Premises do not constitute a "Dwelling Unit" or "Dwelling" as the term
is used in California Civil Code section 1940, et seq. Tenant waives any right
to make repairs at Landlord's expense pursuant to California Civil Code section
1942 or any similar law, statute or ordinance.

ARTICLE 31 - REMEDIES

        31.1 If Tenant is in default of this Lease, then Landlord may avail
itself of any remedies under law, Landlord's election of any particular remedy
to be at Landlord's sole discretion, without obligation under Article 35.1.
Landlord may elect to avail itself of the remedy described in California Civil
Code section 1951.4, in which case this Lease shall continue in full force and
effect after Tenant's breach and abandonment, and notwithstanding anything to
the contrary contained in Article 26, Tenant shall thereafter have the right to
sublet or assign this Lease subject only to reasonable limitations. If Landlord
does not elect to avail itself of the remedy described in California Civil Code
section 1951.4 and Tenant either breaches this Lease and abandons the Premises
before the end of the Term, or Tenant's right to possession is terminated by the
Landlord because of a breach of this Lease, then this Lease shall terminate, and
Landlord shall recover from Tenant the following:

                (a)     The worth at the time of award of the unpaid rent which
                        had been earned at time of termination;

                (b)     The worth at the time of award of the amount by which
                        the unpaid rent which would have been earned after
                        termination until the time of award exceeds the amount
                        of such rental loss that Tenant proves could have been
                        reasonably avoided;

                (c)     The worth at the time of award of the amount by which
                        the unpaid rent for the balance of the Term after the
                        time of award exceeds the amount of such rental loss
                        that Tenant proves could be reasonably avoided; and

                (d)     Any other amount necessary to compensate Landlord for
                        all the detriment proximately caused by Tenant's failure
                        to perform Tenant's obligations under this Lease, or
                        which in the ordinary course of things would be likely
                        to result therefrom (including, without limitation, any
                        costs of obtaining mitigating rental income, such as
                        excused rent, brokerage commissions, Tenant
                        improvements, parking concessions, lease takeovers, cash
                        payments, advertising, moving costs or any other cost or
                        Tenant concession related to the re-leasing of the
                        Premises upon the default of Tenant).

The "worth at the time of award" of the amounts referred to in subparagraphs (a)
and (b), above, shall be computed by allowing interest at the rate specified in
Article 35.11 of this Lease, compounded monthly; and the "worth at the time of
award" of the amounts referred to in subparagraph (c), above, shall be computed
by discounting such amount at the discount rate of the Federal Reserve Bank of
San Francisco at the time of award, plus one percent (1%).

        31.2 Tenant waives any equity of redemption and any right to relief from
forfeiture as provided by California Code of Civil Procedure section 1179 (or
any other similar applicable statute, regulation or law now or hereafter in
effect).

        31.3 Any liability for damages, breach or nonperformance by Landlord, or
arising out of the subject matter of or the relationship created by, this Lease,
will be collectible only out of Landlord's interest in the Building and no
personal liability is assumed by or will at any time be asserted against
Landlord, its parent and affiliated corporations, its and their partners,
venturers, directors, officers, agents, servants and employees, or any of its or
their successors or assigns; all such liability, if any, being expressly waived
and released by Tenant.


ARTICLE 32 - ATTORNEYS' FEES

        32.1 In any action brought by either Landlord or Tenant against the
other to enforce or interpret any provision of this Lease (including any claim
in a bankruptcy or an assignment for the benefit of creditors), the prevailing
party shall recover from the other party all reasonable costs and attorneys'
fees of such action (including those incurred either prior to such action in the
proposed resolution or contemplation of such action, in a prior unlawful
detainer action rendered moot by Tenant's vacancy, in the maintenance or
enforcement of any judgment resulting from said action, or in the appeal from
any such judgment), whether such costs were incurred or services were performed
by in-house or outside counsel.

<PAGE>   22

ARTICLE 33 - WAIVER OF JURY TRIAL

        33.1 Landlord and Tenant each hereby waive their respective rights to
trial by jury of any cause of action, claim, counterclaim or cross-complaint in
any action, proceeding and/or hearing brought by either Landlord against Tenant,
or Tenant against Landlord, as to any matter whatsoever arising out of or in any
way connected with this Lease, the relationship of Landlord and Tenant, Tenant's
use or occupancy of the Premises, any claim of injury or damage, or the
enforcement of any remedy under any law, statue, or regulation, emergency or
otherwise, now or hereafter in effect. Notwithstanding the foregoing, Landlord
and Tenant agree that this waiver shall not be effective where the legal effect
of such waiver would be to invalidate in whole or in part, or to limit or impair
in any manner any policy of insurance in force for the benefit of Landlord or
Tenant or to limit or impair any rights, remedies or coverage afforded
thereunder.


ARTICLE 34 - NOTICES [SEE ADDENDUM]

        34.1 Notice shall be given to Tenant at the Premises. Notice shall be
given to Landlord at 15760 Ventura Boulevard, Suite 500, Encino, California
91436-3095. Either party may, by written notice to the other, specify a
different address for notice purposes.

        34.2 In order to prevent disputes concerning the giving of notice, if
any provision of this Lease (or addenda or amendments thereto) requires "notice"
to be given, for either party to "notify" the other, or otherwise refers to
"notification", then such notice shall be made in writing and be given by either
personal delivery, certified mail or a nationally recognized overnight courier
service, in each case delivery to be evidenced by a signed receipt therefor.
Notice may also be given by facsimile transmission, provided the party to whom
the transmission is addressed acknowledges actual, legible receipt by executing
a copy of the transmission (or a receipt for same) and returning a copy of same
to the sender, by facsimile transmission or otherwise. Notices shall be deemed
effective at the time of delivery, as confirmed by said signed receipts. If
either party fails or refuses to accept delivery by certified mail or overnight
courier service, or refuses to execute a receipt evidencing delivery, then
notice may be given by first-class mail and shall be deemed effective two (2)
business days after mailing.

        34.3 The term "notice" shall not include any bills, invoices, rent
statements or statement of any other charges or sums due from Tenant to
Landlord, or any notice required or permitted to be given pursuant to any law or
statute.


ARTICLE 35 - GENERAL PROVISIONS

        35.1 Reasonableness. Except as may be otherwise specifically provided in
this Lease, wheresoever and whenever Landlord's or Tenant's discretion or
consent is required under this Lease, Landlord and Tenant agree that such
discretion will be reasonably exercised and that such consent will not be
unreasonably withheld or delayed.

        35.2 Rules and Regulations. Tenant shall faithfully observe and comply
with the Rules and Regulations attached hereto as Exhibit "C", and all
reasonable and nondiscriminatory modifications or additions thereto made by
Landlord from time to time.

under the laws of the State of California.

        35.4 Venue. Any lawsuit brought by Tenant against Landlord shall be

who shall be jointly and severally liable for the keeping, observing and
performing of all of the terms, covenants, conditions, provisions and agreements
of this Lease to be kept, observed and performed by Tenant. Notice from or to
any single person or entity executing this Lease as Tenant shall be deemed to be
effective notice from or to each and every person or entity executing this Lease
as Tenant, with the same force or effect as if each such person or entity had so
given or received such notice. Any act or signature by any single person or
entity executing this Lease as Tenant concerning this tenancy or Lease

or modification of this Lease) shall be binding upon each person or entity
executing this Lease as Tenant with the same force and effect as if each person
or entity had so acted or signed. Any refund to any single person or entity
executing this Lease as Tenant shall be deemed to be a refund to each person or
entity executing this Lease as Tenant, as if each such refund had been
collectively made to all such persons or entities.

        35.6 Successors and Assigns. Except as otherwise provided in this Lease,
each covenant, condition and provision of this Lease shall be binding upon and

        35.7 Relinquishment of Possession. The voluntary or involuntary
relinquishment of possession of the Premises by Tenant to Landlord, or a mutual
cancellation of this Lease by both Tenant and Landlord, shall at the option of
Landlord operate as an assignment to Landlord of any or all subleases or
subtenancies and no merger shall be effected.

        35.8 Performance by Tenant. If Tenant fails to perform any act to be
performed by Tenant hereunder other than payment of money to Landlord and such
failure continues for ten (10) days after Tenant's receipt of notice thereof
from Landlord, Landlord may, without waiving or releasing Tenant from any
obligation, perform any such act and all costs incurred by Landlord, together
with interest thereon at the rate specified in Article 35.11 of this Lease from
the date of such payment by Landlord, shall be payable by Tenant to Landlord.

        35.9 Definition of Landlord. The term "Landlord" as used in this Lease
shall be limited to mean and include only the owner at the time in question of
the fee or leasehold interest under a ground lease of the Land. If Landlord
transfers, assigns or otherwise conveys any such title or leasehold, Landlord
shall be automatically freed and relieved of all liability with respect to the
performance of any covenants or obligations in this Lease to be performed from
and after the date of such transfer, assignment or conveyance, except as may be
provided in Article 7.3.

        35.10 Waiver. The waiver by Landlord of any breach of any term, covenant
or condition of this Lease shall neither be deemed a waiver of any concurrent or
subsequent breach of the same or any other term, covenant or condition of this
Lease, nor shall any custom or practice which may develop between the parties in
the administration of the terms hereof be deemed a waiver of, or in any way
affect the right of Landlord to require strict performance by Tenant. The
acceptance of rent or any sum hereunder by Landlord shall not be deemed to be a
waiver of any breach by Tenant of any term, covenant or condition of this Lease
other than the failure of Tenant to pay such rent or sum, regardless of
Landlord's knowledge of such breach at the time of acceptance.

        35.11 Interest. Wheresoever required in this Lease, and in lieu of the
legal rate to be used in the computation of any interest owed Landlord in any
judgment or award of the court, interest shall be compounded monthly and charged
at a rate equal to the higher of:

                (a)     Ten percent (10%) per annum; or

                (b)     Five percent (5%) per annum, plus the rate established
                        by the Federal Reserve Bank of San Francisco on advances
                        to member banks under Sections 13 and 13(a) of the
                        Federal Reserve Act (as now in effect, or hereafter from
                        time to time amended or, if there is no such single
                        terminable rate of advances, the closest counterpart of
                        such rate as shall be designated by the Superintendent
                        of Banks of the State of California, unless some other
                        person or agency is delegated such authority by the
                        legislature) which is prevailing on the twenty-fifth
                        (25th) day of the month preceding the "Accrual Date".

The "Accrual Date" shall be defined as follows: for purposes of Article 30, as
the initial date of default; for purposes of Article 6, the date of final
payment by Landlord for the Capital Expense; and for all other purposes, the
date of execution of this Lease. Tenant hereby agrees that the use of such
interest rate herein shall not be deemed to be interest upon a loan or
forbearance of money, for goods or things in action for use primarily for
personal, family or household purposes within the meaning of the California
Constitution, Article 15, section 1.

        35.12 Terms, Headings and Print. The words "Landlord" and "Tenant" as
used herein shall include the plural as well as the singular. Words used in any
gender include other genders. The article headings are not a part of this Lease,
and such headings and any use of boldface, italics or underlining are for
convenience only, and shall have no effect upon the construction or
interpretation of this Lease.

        35.13 Time. Time is of the essence with respect to the performance of
every provision of this Lease in which time of performance is a factor.

        35.14 Entire Agreement. This Lease contains the entire agreement of the
parties hereto with respect to any matter covered or mentioned in this Lease and
no prior agreement or understanding, oral or written, expressed or implied,
pertaining to any such matter shall be effective for any purpose. No provision
of this Lease may be amended or added to except by an agreement in writing
executed by both Landlord and Tenant or their respective successors in interest.
The parties acknowledge that all prior agreements, representations and
negotiations concerning the subject matter of this Lease, or collateral thereto,
are deemed superseded by the execution of this Lease to the extent they are not
incorporated herein and that this agreement shall be deemed to be integrated.

        35.15 Severability. Any provision of this Lease which proves to be
invalid, void or illegal shall in no way affect, impair or invalidate any other
provisions hereof, and such other provisions shall remain in full force and
effect.

        35.16 Recording. Tenant shall not record this Lease or a short form
memorandum thereof without the written consent of Landlord. Any recording
without Landlord's written consent shall be a material breach of this Lease.

        35.17 Plats, Riders and Clauses. Any addenda, clauses, plats, riders and
provisions executed by both Landlord and Tenant which are inserted in, endorsed
on or affixed to this Lease are a part hereof. If there is any variation or
discrepancy between duplicate original documents held by Landlord and Tenant,
then the duplicate original held by Landlord shall be deemed controlling.

        35.18 Building Name. Tenant shall not use the name of the Building for
any purpose other than as the address of the business to be conducted by Tenant
in the Premises. Landlord shall have the right, without liability to Tenant for
any damage or injury, whatsoever, to change the name or street address of the
Building.

        35.19 Quiet Possession. Except as otherwise provided in this Lease,
Tenant, upon paying the rents reserved hereunder and observing and performing
all of the covenants, conditions and provisions on Tenant's part to be observed
and performed hereunder, shall have quiet possession of the Premises for the
entire Term.

        35.20 Cumulative Remedies. No remedy or election hereunder shall be
deemed exclusive and, wherever possible, each remedy shall be cumulative with
all other remedies.

        35.21 Examination and Delivery of Lease. Submission of this instrument
for examination or signature by Tenant does not constitute a reservation of, or
option to Lease and is not effective as a Lease or otherwise, or a binding legal
instrument until execution and delivery by all parties. Prior to such execution
and delivery, this Lease shall neither be legally binding nor effective.

        35.22 Confidentiality. Tenant agrees to keep the terms of this Lease
confidential and shall not disclose same to any other person not a party hereto
without the prior written consent of Landlord; however, Tenant may disclose the
terms hereof to Tenant's accountants, attorneys, managing employees, and others
in privity with Tenant to the extent reasonably necessary for Tenant's business
purposes. Tenant agrees that a breach of this Article will cause irreparable
injury to Landlord and Landlord shall be entitled, together with all other
remedies in law or equity available to Landlord, to injunctive relief to
restrain such breach.

        35.23 Agreed Figures. All figures set forth in this Lease represent
negotiated sums and percentages and are conclusive as between Landlord and
Tenant.

        35.24 Measurement of Premises. The usable area of the Premises has been
measured consistent with the American National Standard Institute Publication
ANSI Z65.1 - 1996 ("BOMA"). The rentable area of the Premises and Building
include a factor for those Common Areas on the floor containing the Premises and
an additional factor for those Common Areas which generally serve rentable areas
of the Building (such as the Ground Floor Lobby), and exclude those areas
designated exclusively as storage space. If Landlord elects to remeasure the
Premises, Common Areas, Building or any portion thereof, or the use of any
portion of the Building is modified so as to affect the gross rentable square
footage of the Building, then Landlord may upon written notice to Tenant revise
the Proportional Share to reflect the results of any such survey or
modification, provided that such remeasurement is consistent with the method of
measurement and calculation of rentable area set forth herein.

                This Addendum dated November 24, 1999, is made a part of and is
attached to that certain Lease dated November 24, 1999, between Stevens Creek

ARTICLE 36 - TENANT IMPROVEMENTS

        36.1 Landlord shall provide Tenant with a "Construction Allowance" in
the amount of Three Hundred Thousand Nine Hundred Ninety-Two Dollars
($300,992.00), such amount to be applied toward construction of permanent
improvements (including cabling) in the Premises ("Tenant Improvements") in
accordance with the Work Letter attached hereto as Exhibit "E".

        36.2 Notwithstanding anything to the contrary contained herein or in the
Work Letter, Tenant may use a portion of the Construction Allowance not to
exceed One Hundred Twelve Thousand Eight Hundred Seventy-Two Dollars
($112,872.00) to reimburse Tenant for the purchase of fixtures, furnishings and
equipment for the Premises (the "FF&E"), and a portion of the Construction
Allowance not to exceed Twenty-Eight Thousand Two Hundred Eighteen Dollars
($28,218.00) to reimburse Tenant for the costs of moving Tenant's fixtures,
furnishings and equipment to the Premises by qualified licensed and insured
movers (the "Moving Expenses"). Landlord shall have no obligation to reimburse
Tenant for FF&E or Moving Expenses unless and until Landlord, in Landlord's sole
discretion, is satisfied that there is or will be Construction Allowance
remaining after the completion of all Tenant's Work and payment of those Work
Costs other than FF&E and Moving Expenses that may result in a lien upon the
Land and Building. Landlord shall not be obligated to reimburse Tenant for FF&E
unless and until the FF&E subject to the reimbursement request is delivered and
installed in the Premises and functioning to Tenant's satisfaction. Landlord
shall not be obligated to reimburse Tenant for Moving Expenses unless and until
the moving activities included in the Moving Expenses subject to the
reimbursement request have been performed to Tenant's reasonable satisfaction.
Any reimbursement of FF&E or Moving Expenses shall be subject to offset by
Landlord for the reasonable costs of repairing any damage to the Building and
Common Areas caused by the subcontractors performing the work subject to the
request for reimbursement.


ARTICLE 37 - OPTION TO RENEW

        37.1 Tenant shall have the option to renew this Lease for an additional
term of sixty (60) months (the "Renewal Term"), upon the following terms and
conditions:

                (a)     Tenant shall not at the time of exercising this Option
                        be in material monetary default (with all applicable
                        notices having been given and cure periods having
                        expired without Tenant having cured such material
                        default) under any of the terms, covenants, conditions,
                        provisions or agreements of this Lease.

                (b)     Such re-leasing shall be upon the same terms, covenants,
                        conditions, provisions and agreements as in this Lease,
                        except that:

                        (i)     Tenant's Basic Monthly Rent shall be an amount
                                determined by multiplying the rentable area of
                                the Premises by the "Fair Market Rate" (as
                                defined in Article 37.3).

                        (ii)    Tenant's Base Year shall be amended to be the
                                calendar year 2005.

                        (iii)   Tenant shall continue in the Premises in its "as
                                is" condition.

                (c)     Tenant shall exercise this option to renew this Lease by
                        notifying Landlord of the same in writing on or before
                        May 31, 2004, or this option shall be null, void and of
                        no force or effect.

<PAGE>   27

                (d)     Within ten (10) business days after Landlord's receipt
                        of Tenant's notice of exercise of this Option, Landlord
                        shall propose to Tenant the Fair Market Rate for the
                        Renewal Term (based upon the definition in Article
                        37.3).

                (e)     Landlord and Tenant shall thereafter continue to
                        negotiate Fair Market Rate in good faith until the
                        earlier of the agreement of the parties or November 30,
                        2004 (the "Outside Agreement Date").

                (f)     If the parties have not reached agreement on Fair Market
                        Rate by the Outside Agreement Date, then the last such
                        proposal for the Fair Market Rate submitted by each
                        party to the other prior to the Outside Agreement Date
                        shall be submitted to arbitration in accordance with
                        Article 37.2.

        37.2 If arbitration is required pursuant to Article 37.1, then the
parties shall proceed as follows:

                (a)     Each arbitrator appointed hereunder shall be a licensed
                        real estate professional who shall have been active over
                        the five (5) year period immediately prior to the date
                        of such appointment in the leasing of first-class
                        commercial high-rise office properties in the Market
                        Area (defined in Article 37.3, below), and who does not
                        then represent or act on behalf of either of the
                        parties.

                (b)     If Landlord and Tenant cannot agree to a single
                        arbitrator within ten (10) business days after the
                        Outside Agreement Date, then Landlord and Tenant shall
                        each appoint one (1) arbitrator within such ten (10)
                        business day period; however, if one (1) party fails to
                        timely appoint an arbitrator, and further fails to
                        appoint an arbitrator within two (2) business days after
                        receipt of written notice of such failure from the other
                        party, then the determination shall be made by the sole
                        appointed arbitrator.

                (c)     If a sole arbitrator is not agreed upon or deemed
                        selected, then the two (2) qualified arbitrators so
                        appointed shall, within ten (10) business days
                        thereafter, appoint a third (3rd) arbitrator having the
                        same minimum required qualifications; however, if the
                        two (2) arbitrators fail to agree upon and appoint a
                        third (3rd) arbitrator, then the identity of the third
                        (3rd) arbitrator shall be submitted to arbitration under
                        the provisions of the American Arbitration Association,
                        but subject to such arbitrator having the foregoing
                        qualifications.

                (d)     The determination of the arbitrator(s) shall be limited
                        solely to the issue of whether Landlord's or Tenant's
                        submitted Fair Market Rate is closer to the actual Fair
                        Market Rate for such space. The arbitrator(s) shall have
                        no authority to issue any decision other than the
                        selection of either Landlord's or Tenant's submitted
                        Fair Market Rate.

                (e)     A majority of the arbitrator(s) shall, within thirty
                        (30) days after the appointment of the last arbitrator,
                        reach a decision consistent with subparagraph (d),
                        above, and shall notify Landlord and Tenant thereof. The
                        decision of the arbitrator(s) shall be binding upon both
                        Landlord and Tenant.

                (f)     The losing party shall be responsible for paying all
                        reasonable fees of the arbitrator(s) hereunder.

        37.3 For purposes of this Lease, the term "Fair Market Rate" shall mean
a single Basic Monthly Rent per rentable square foot (such rate to amortize over
the term any mid-term increases or indexing, and excused rent to reach a single
effective rate payable in each month of the term) that a landlord has accepted
in current transactions from new or renewing non-equity tenants (not affiliated
with Landlord) of comparable credit-worthiness, for a comparable amount of
improved space, for a comparable use for a comparable term with a commencement
date within six (6) months of the commencement of the renewal term ("Comparable
Transactions"). If there are at least two (2) Comparable Transactions in the
Building, then the Fair Market Rate shall be determined considering only those
Comparable Transactions in the Building. If there are not at least two (2) such
Comparable Transactions in the Building, then such determination shall be made
further considering what comparable landlords of comparable buildings (which
shall each be of a comparable size, class and age in the Downtown Long Beach
area fronting on Ocean Boulevard [the "Market Area"], and with comparable
vacancy) have accepted in Comparable Transactions. Although determination of
Fair Market Rent shall be limited to determination of the Basic Monthly Rent per
rentable square foot, in comparison of Comparable Transactions appropriate
consideration shall be given to differences in the method of measuring the area
of the premises, the ratio of rentable to usable square area, whether rent is
based upon usable or rentable area, and the type of escalation clause (e.g.,
whether increases in additional rent are determined on a net or gross basis and,
if gross, whether such increases are determined according to a base year or a
base dollar amount expense stop); the extent to which the premises have been or
are obligated to be improved; whether or not a brokerage commission was payable;
and, any other customary concession granted the tenant in the Comparable
Transaction.

ARTICLE 38 - SIGNS

        38.1 Full Floor Signage. Effective upon the Commencement Date for Suite
2000A, Tenant shall be entitled to the sign rights set forth therein.
Notwithstanding anything to the contrary contained in Article 23, Tenant shall
have the right to install signs in Premises visible from, but not within, the
elevator lobby on the Twentieth (20th) Floor, identifying Tenant by Tenant's
name and/or logo. Tenant may design and construct the Premises (incorporating
such improvements as may be required by any fire/life safety codes applicable to
the Premises and elevator lobby at Tenant's sole cost and expense, for which
Tenant may use the Construction Allowance) so that the doors from the elevator
lobby to the Premises may remain open for the conduct of normal business.

        38.2 Monument Signage. Effective upon the Commencement Date for Suite
2000A, Tenant shall have the non-exclusive right to place Tenant's name on one
(1) insert on each of the two (2) sides of either the existing monument sign at
the Ocean Boulevard entrance to the Building or any additional monument sign
that may be installed by Landlord along the Ocean Boulevard frontage of the
Building (the "Sign") upon the following terms and conditions:

                (a)     Tenant's rights hereunder shall be subject to all rights
                        granted to other tenants in the Building existing as of
                        the execution of this Amendment (the "Prior Rights");
                        and, shall be further subject to space on the Sign
                        becoming available, unencumbered by any Prior Rights.
                        Landlord shall not be obligated to reduce the size of
                        any inserts or increase the number of inserts which the
                        Sign can accommodate to create an opportunity for Tenant
                        to install Tenant's name on the Sign. Tenant is advised
                        that there are, as of the execution of this Lease,
                        rights to the Sign superior to those granted herein to
                        Tenant.

                (b)     Tenant's right to install and maintain Tenant's inserts
                        on the Sign is subject to:

                        (i)     Tenant not being in default of this Lease, with
                                all applicable notices having been given and
                                cure periods having expired; and

                        (ii)    The occupancy for the conduct of business by
                                Tenant and affiliates of Tenant of not less than
                                eighteen thousand eight hundred twelve rentable
                                square feet (18,812 RSF) of the Premises (e.g.,
                                the entire Twentieth (20th) Floor).

                        If at the time that Tenant's sign rights accrue, Tenant
                        fails to satisfy any requirement hereunder, then this
                        Article 38.2 shall be deemed deleted and of no further
                        force or effect. If at any time after installation of
                        the Sign, Tenant fails to satisfy either of the above
                        requirements, and continues to do so for a period of
                        thirty (30) days, then Landlord by notice to Tenant may
                        require Tenant to remove the Sign in accordance with
                        subparagraph (j), below, and shall thereafter forfeit
                        all rights to replace such Sign for the remainder of the
                        Term (as may be extended).

                (c)     The cost to fabricate, construct, install, repair and
                        maintain Tenant's inserts on the Sign shall be borne
                        solely by Tenant, and Tenant shall keep Tenant's inserts
                        on the Sign in good order, condition and repair. If
                        Tenant changes Tenant's legal name, then Tenant shall
                        promptly replace the inserts on the Sign with correct
                        inserts, at Tenant's sole cost and expense. Landlord may
                        determine, in Landlord's sole discretion, in which slot
                        Tenant's inserts shall be placed.

                (d)     Tenant's inserts on the Sign shall have the same
                        dimensions as those other inserts on the Sign, and
                        materials used to construct Tenant's inserts shall be of
                        the same composition as the existing inserts on the
                        Sign.

                (e)     Tenant shall secure Landlord's prior written approval as
                        to the design, size, color, construction and other
                        aesthetic aspects of Tenant's inserts on the Sign.

                (f)     Prior to installation or any modification of Tenant's
                        inserts on the Sign, Tenant or Tenant's contractors
                        shall obtain all required plans, permits and government
                        approvals which may be required.

                (g)     Tenant shall indemnify and defend Landlord in regards to
                        the installation and maintenance of Tenant's inserts on
                        the Sign to the same extent as with respect to the
                        Premises.

                (h)     Tenant shall insure Tenant's inserts on the Sign to the
                        same extent as Tenant is obligated to insure Tenant's
                        personal property in the Premises.

                (i)     Landlord reserves the right to erect such other signs in
                        the Common Areas, the real property upon which the
                        Building is situated, the parking facilities, and
                        otherwise upon the interior and exterior of the Building
                        as Landlord in its sole discretion deems appropriate,
                        and any such installation shall not serve to increase
                        Tenant's rights hereunder.

<PAGE>   29

                (f)     At the end of the Term (or as may be required pursuant
                        to subparagraph [b], above) Tenant shall, at Tenant's
                        sole cost and expense, remove the Sign and repair and
                        restore the area of the monument in which the Sign
                        panels were located to their original or blank
                        condition.

                (g)     The rights under this Article 38 are personal to Tenant
                        or any affiliate of Tenant defined in Article 26.10, and
                        may not be sublet or assigned to any other entity.


ARTICLE 39 - RIGHT TO AUDIT

        39.1 Tenant shall have a right to audit Landlord's determination of Tax
Rent, Operating Expense Rent and Capital Expense Rent and the respective
Property Taxes, Operating Expenses and Capital Expenses upon which the same were
based (collectively, "Escalations"), upon the following terms and conditions:

                (a)     Tenant shall not be in material monetary default of this
                        Lease (including, but not limited to payment of any
                        charges to be reviewed hereunder) at the time notice of
                        audit is given by Tenant, or at any other time prior to
                        completion of the audit.

                (b)     Any audit shall be limited to those annual
                        determinations of actual Escalations that Landlord is
                        required to make pursuant to Articles 4, 5 and 6, and
                        shall not include a right to audit Landlord's estimates
                        of Escalations that Landlord is required to make
                        thereunder.

                (c)     Each audit shall be limited to the Escalations for not
                        more than two (2) consecutive Comparison Years of the
                        Term and, in the case of the first audit performed, the
                        Base Year. No Escalations for any Comparison Year or the
                        Base Year may be audited more than once. For any
                        Comparison Year, Tenant shall notify Landlord that it is
                        exercising its right to audit Escalations for such
                        Comparison Year not later than a date two (2) years
                        after Tenant's receipt of Landlord's statement
                        reconciling the Escalations for such Comparison Year.
                        With respect to each Comparison Year, if Tenant fails to
                        give timely notice of exercise of Tenant's rights (or
                        such notice is not effective because of Tenant's default
                        pursuant to subparagraph [a], above), then Tenant shall
                        be deemed to have accepted Landlord's statement of such
                        Escalations and be deemed to have waived any claim with
                        respect to such Escalations, except as such claim may
                        arise from the fraud or other intentional tort on the
                        part of Landlord.

                (d)     The audit shall take place at Landlord's regional
                        offices within the Los Angeles Metropolitan area or, at
                        Landlord's option, the Building, at a time mutually
                        convenient to Landlord and Tenant (but not later than
                        sixty [60] days after receipt of Tenant's notice to
                        audit). Except as Landlord may consent in writing, and
                        provided Landlord has fully cooperated with Tenant's
                        auditors to supply requested information on a prompt
                        bases, the audit shall be completed within ten (10)
                        consecutive business days after commencement.

                (e)     The audit may be accomplished by either Tenant's own
                        employees with accounting experience reasonably
                        sufficient to conduct such review, or a nationally or
                        regionally recognized public accounting firm mutually
                        acceptable to Landlord and Tenant that is not
                        compensated on a contingency or bonus basis. Under no
                        circumstances shall Landlord be required to consent to
                        an accounting firm which is also a tenant of Landlord in
                        the Building.

                (f)     If it is determined that Tenant overpaid Escalations,
                        Landlord shall repay to Tenant the amount of the
                        overpayment to the extent that Landlord does not dispute
                        the results of such audit. If the audit determines that
                        Tenant underpaid Escalations, then Tenant shall promptly
                        pay to Landlord the amount of any such underpayment.

                (g)     If the audit is performed by a nationally or regionally
                        recognized public accounting firm, and it is determined
                        that the total Property Taxes, Operating Expense and
                        Capital Expenses subject to audit (as opposed to the
                        resulting calculations of Tax Rent, Operating Expense
                        Rent and Capital Expense Rent) were overstated by
                        Landlord by more than five percent (5%), then Landlord
                        shall reimburse Tenant for all actual and reasonable
                        expenses incurred to such firm in auditing the same.

                (h)     Tenant agrees to keep all information acquired, as a
                        result of Tenant's exercise of its rights, hereunder,
                        confidential and shall not disclose same to any other
                        person not a party hereto without the prior written
                        consent of Landlord; however, Tenant may disclose the
                        terms hereof to the mutually agreed upon auditor,
                        Tenant's accountants, attorneys, managing employees,
                        assignees, sublessees, other persons and entities as may
                        be required pursuant to legal process or other legal
                        requirements, and others in privity with Tenant only to
                        the extent reasonably necessary for Tenant to exercise
                        its rights hereunder. Any accounting firm hired by
                        Tenant to perform the audit shall likewise agree in
                        writing to the foregoing as a condition of Landlord
                        consenting to the employment of such firm or such firm
                        being provided access to Landlord's records.

                (i)     If Tenant fails to notify Landlord of Tenant's exercise
                        of Tenant's right to audit (or subsequently perform such
                        audit) within the time periods specified herein, then
                        Tenant shall be deemed to have accepted as correct
                        Landlord's statement of Escalations and shall waive any
                        and all claims in regard to the same; however, nothing
                        herein shall be deemed a waiver of any claim for fraud
                        or other intentional tort on the part of Landlord.

        39.2 The submittal of all matters to arbitration in accordance with the
terms and conditions of this Article 39.2 shall be the sole and exclusive
method, means and procedure to resolve any and all claims, disputes or
disagreements arising in regard to any dispute by Landlord pursuant to Article
39.1(f), Landlord's election pursuant to Article 6 to amortize certain items of
Capital Expenses (including, without limitation, the determination of useful
life or payback period by Landlord) or the extent to which costs incurred by
Landlord shall be included as an item of Capital Expenses, as follows:

                (a)     The parties hereby irrevocably waive any and all rights
                        to the contrary and shall at all times conduct
                        themselves in strict, full, complete and timely
                        accordance with the terms and conditions of this Article
                        39.2 and all attempts to circumvent this Article 39.2
                        shall be absolutely null and void and of no force or
                        effect whatsoever.

                (b)     Any payment to Landlord can be made "under protest,"
                        which shall occur when such payment is accompanied by a
                        good faith notice stating the reasons that the party has
                        elected to make a payment under protest. Such protest
                        will be deemed waived unless the subject matter
                        identified in the protest is submitted to arbitration as
                        set forth in this Article 39.2.

                (c)     Any dispute to be arbitrated pursuant to the provisions
                        of this Article 39.2 shall be determined by binding
                        arbitration before a retired judge of the Superior Court
                        of the State of California (the "Arbitrator") under the
                        auspices of Judicial Arbitration & Mediation Services,
                        Inc. ("JAMS"), or any other similar arbitration or
                        mediation service to which the parties may agree,
                        subject to the following:

                        (i)     Such arbitration shall be initiated by the
                                parties, or either of them, within ten (10) days
                                after either party sends Notice (the
                                "Arbitration Notice") of a demand to arbitrate
                                to the other party and to JAMS. The Arbitration
                                Notice shall contain a description of the
                                subject matter of the arbitration, the dispute
                                with respect thereto, the amount involved, if
                                any, and the remedy or determination sought.

                        (ii)    The parties may agree on a retired judge from
                                the JAMS panel. If they are unable to promptly
                                agree, JAMS will provide a list of three
                                available judges and each party may strike one.
                                The remaining judge (or if there are two, the
                                one selected by JAMS) will serve as the
                                Arbitrator. In the event that JAMS shall no
                                longer exist or if JAMS fails or refuses to
                                accept submission of such dispute and the
                                parties cannot agree on another similar service,
                                then the dispute shall be resolved by binding
                                arbitration before the American Arbitration
                                Association ("AAA") under the AAA's commercial
                                arbitration rules then in effect.

                        (iii)   The Arbitrator shall schedule a pre-hearing
                                conference to resolve procedural matters,
                                arrange for the exchange of information, obtain
                                stipulations, and narrow the issues. The parties
                                will submit proposed discovery schedules to the
                                Arbitrator at the pre-hearing conference. The
                                scope and duration of discovery will be within
                                the sole discretion of the Arbitrator. The
                                Arbitrator shall have the discretion to order a
                                pre-hearing exchange of information by the
                                parties, including, without limitation,
                                production of requested documents, exchange of
                                summaries of testimony of proposed witnesses,
                                and examination by deposition of parties and
                                third-party witnesses. This discretion shall be
                                exercised in favor of discovery reasonable under
                                the circumstances.

                        (iv)    The arbitration shall be conducted in the County
                                of Los Angeles, California. Any party may be
                                represented by counsel or other authorized
                                representative.

                        (v)     In rendering a decision(s), the Arbitrator shall
                                determine the rights and obligations of the
                                parties according to the substantive and
                                procedural laws of the State of California and
                                the terms and conditions of this Lease. The
                                Arbitrator's decision shall be based on the
                                evidence introduced at the hearing, including
                                all logical and reasonable inferences therefrom.

                        (vi)    The Arbitrator may make any determination,
                                and/or grant any remedy or relief (an
                                "Arbitration Award") that is just and equitable.
                                The decision must be based on, and accompanied
                                by, a written statement of decision explaining
                                the factual and legal basis for the decision as
                                to each of the principal controverted issues.

                        (vii)   The decision shall be conclusive and binding,
                                and it may thereafter be confirmed as a judgment
                                by the Superior Court of the State of
                                California, subject only to challenge on the
                                grounds set forth in the California Code of
                                Civil Procedure Section 1286.2. The validity and
                                enforceability of the Arbitrator's decision is
                                to be determined exclusively by the California
                                courts pursuant to the terms and conditions of
                                this Lease.

                        (viii)  The Arbitrator shall award costs, including
                                without limitation attorneys' fees, and expert
                                and witness costs, to the prevailing party as
                                defined in California Code of Civil Procedure
                                Section 1032 ("Prevailing Party"), if any, as
                                determined by the Arbitrator in his or her
                                discretion. The Arbitrator's fees and costs
                                shall be paid by the non-prevailing party as
                                determined by the Arbitrator in his or her
                                discretion.

                (d)     This Article 39.2 shall not apply to any claims by
                        Tenant that are primarily founded upon matters of fraud,
                        willful misconduct, bad faith or any other allegation of
                        an intentional tortious act.

                (a)     Repairs or other work occasioned by fire or other
                        casualty to the extent of actual insurance proceeds
                        received by Landlord (however, any deductibles under
                        such policy shall be included in Operating Expenses);

                (b)     Leasing commissions, attorneys' fees, costs and

                        occupants or prospective tenants or prospective tenants
                        or occupants;

                (c)     Renovating, decorating, painting, redecorating or making
                        leasehold improvements to the interior of the existing
                        or prospective premises of other tenants, or storage
                        space, in the Building, but not excluding costs and
                        expenses of such work in the Common Areas of the
                        Building;

                (d)     Services to tenants for which Landlord is reimbursed by
                        tenants under the leases with such tenants (excepting
                        fees for parking);

                (e)     Depreciation, interest on any mortgage, and rent under
                        any ground lease;

                (f)     Violations of this Lease by Landlord and violations by
                        other tenants of provisions of their leases (however, if
                        such violation results in an insured loss, then any
                        deductibles under such policy shall be included in
                        Operating Expenses);

                (g)     Insurance deductibles to the extent that the same exceed
                        an aggregate of Fifty Thousand Dollars in a calendar
                        year;

                (h)     Without waiving Landlord's right to include the same in
                        Capital Expenses to the extent permitted pursuant to
                        Article 6, any costs or expenses required to be
                        capitalized according to generally accepted accounting
                        principles applicable to, and generally recognized by
                        the commercial office real estate industry; and

                (i)     Earthquake insurance, unless earthquake insurance was
                        included in the Base Year.

        5.7 If any facilities, services or utilities used in connection with the
Building are provided from another building owned or operated by Landlord (or an
affiliate of Landlord), or vice versa, the costs incurred by Landlord in
connection therewith shall be equitably pro rated and allocated to Operating
Expenses by Landlord on an reasonable basis.

ADDENDUM TO ARTICLE 6 - CAPITAL EXPENSE RENT

        6.5 Notwithstanding anything to the contrary contained in Article 6, for
purposes of this Lease, only, Capital Expenses shall be subject to the following
provisions:

                (a)     Each item of Capital Expenses defined in subparagraph
                        (a) or (c) of Article 6.2 incurred during any calendar
                        year in which all or any part of the Term occurs and
                        costing in excess of Fifty Thousand Dollars ($50,000.00)
                        shall be amortized with interest as provided in Article
                        35.11, in equal installments, over its "Useful Life"
                        (defined below), and only those installments accruing
                        during any calendar year in which all or any part of the
                        Term occurs shall be included in Capital Expenses for
                        such calendar year; and

                (b)     Each item of Capital Expenses defined in subparagraph
                        (b) of Article 6.2 incurred during any calendar year in
                        which all or any part of the Term occurs shall not
                        exceed the savings in Operating Expenses reasonably
                        projected by Landlord to result and actually resulting
                        therefrom (as reasonably determined by Landlord after
                        consultation with experts experienced in the applicable
                        improvement and calculation of savings therefrom)
                        discounted to present value at the rate specified in
                        Article 35.11, and such lesser amount shall be amortized
                        with interest as provided in Article 35.11, in equal
                        installments, over the payback period for such Capital
                        Expense (as reasonably projected by Landlord), and only
                        those installments accruing during any calendar year in
                        which all or any part of the Term occurs shall be
                        included in Capital Expenses for such calendar year.

The term "Useful Life" for purposes of this Article 6, shall mean and refer to
that period of time which the subject capital improvement, modification or
addition will be productive and/or useful, without replacement, for the purpose
required and intended at the time of installation, assuming that such capital
improvement, modification or addition is repaired and maintained as provided in
this Lease and will be subject to the elements of nature or any other condition
beyond the reasonable control of Landlord (including further governmental action
which renders the improvement, modification or addition obsolete).

        6.6 Notwithstanding anything to the contrary contained in Article 6,
Capital Expenses shall exclude any item of costs incurred by Landlord in the
making or installation of capital improvements, modifications or additions to
the Land, Building, Common Areas and/or the machinery, equipment and facilities
related thereto and arising in connection with renovating, decorating, painting,
redecorating or making leasehold improvements to the premises of existing or
prospective tenants, or to storage space, in the Building, excepting costs and
expenses of such work in those portions of the Common Areas of the Building (a)
that are available for use by Tenant (and do not duplicate facilities on the
Twentieth [20th] Floor of the Building), and (b) which otherwise directly
benefit Tenant by maintaining or enhancing the health or safety of occupants of
the Premises or facilitating access between the Premises and the Common Areas.

        6.7 Notwithstanding anything to the contrary contained herein, that
portion of Capital Expense Rent attributable to Capital Expenses defined
pursuant to subparagraph (c) of Article 6.2 shall not in any calendar year
during the Term exceed a sum determined by multiplying the rentable square
footage of the Premises by 20/100 Dollars ($0.20).


ADDENDUM TO ARTICLE 10 - PARKING LICENSE

        10.2 Notwithstanding anything to the contrary contained herein:

                (a)     Effective from the Commencement Date for Suite 2000A
                        through March 31, 2000, Tenant shall purchase not less
                        than ten (10) parking passes entitling Tenant to park in
                        the Building's parking facility in either the unreserved
                        or reserved mode (parking in the reserved mode to be
                        subject to availability), at the scheduled rates for
                        parking in such mode in effect from time to time; and



                                  Page 7 of 9
<PAGE>   33

                (b)     Effective April 1, 2000, and continuing for the
                        remainder of the Term (as may be extended or renewed),
                        Tenant shall purchase not less than seventy-three (73)
                        parking passes entitling Tenant to park in the
                        Building's parking facility in either the unreserved or
                        reserved mode (parking in the reserved mode to be
                        subject to availability), at the scheduled rates for
                        parking in such mode in effect from time to time.

Any parking purchased by Tenant's Affiliate occupying the Premises shall be
included in determining whether Tenant has fulfilled its requirement hereunder.
The foregoing obligation is referred to herein as the "Minimum Parking
Requirement".

        10.3 Tenant's rights and obligations to satisfy the Minimum Parking
Requirement may not be assigned, sublet, licensed or otherwise transferred to
any third party (other than Tenant's Affiliate), except as follows:

                (a)     Tenant's rights and obligations to satisfy the Minimum
                        Parking Requirement may be transferred by Tenant to
                        Tenant's assignee in conjunction with an assignment of
                        this Lease approved by Landlord in accordance with
                        Article 26; and

                (b)     Tenant may purchase such parking on behalf of any
                        approved subtenant of Tenant and be reimbursed for the
                        same by such subtenant, provided that:

                        (i)     Any such reimbursement shall be at cost, without
                                profit, markup or administrative charge; and

                        (ii)    Tenant may not purchase parking or seek
                                reimbursement from any such subtenant for any
                                portion of the Minimum Parking Requirement that
                                exceeds each such subtenant's share of the
                                Premises (based upon the rentable area of such
                                portion of the Premises exclusively granted and
                                occupied by such subtenant). For example, if
                                after April 1, 2000, a subtenant exclusively
                                subleases and occupies nine thousand three
                                hundred rentable square feet (9,300 RSF) of the
                                Premises, then Tenant may not purchase and seek
                                reimbursement from such subtenant for more than
                                49.43% of the Minimum Parking Requirement, or
                                thirty-six (36) passes; and, if such subtenant
                                requires passes in addition to such amount, then
                                such subtenant must purchase the same directly
                                from Landlord, on a month-to-month basis,
                                subject to availability.

        10.4 Notwithstanding anything to the contrary contained herein, Tenant
or Tenant's Affiliate may purchase such additional parking at the scheduled
rates for parking in such mode in effect from time to time in such amounts and
modes as Landlord may reasonably determine a month-to-month basis.

Plan and Construction Drawings pursuant to sections 4.1 and 4.2, above, and any
cooperation and assistance of Landlord's Representative in the preparation
thereof, is solely for the protection of Landlord's interests in the Land,
Building and Premises, and should not be construed as a waiver of any of
Tenant's or the Tenant Improvements Architect's obligations hereunder to prepare
and modify the Space Plans and Construction Drawings in accordance with sections
4.3 and 4.4. The provisions of this section 4 shall apply equally to any
modifications of approved and/or permitted drawings required hereunder.

                        vacate the Building, Common Areas or Premises of
                        personnel, equipment, materials and supplies to the
                        extent reasonably required to eliminate any such

this Work Letter and the Lease, and Landlord has received appropriate lien
releases from Tenant's Contractor and all subcontractors and suppliers
(including a conditional lien release for any current application for payment,
accompanied by an unconditional lien release for any prior application for
payment for which payment has been made). Tenant shall endeavor to limit
payments to two (2) checks in any thirty (30) day period to Tenant's general
contractor, and a reasonable number of payments to any other direct contractors

telephone and computer cabling services).

        7.4 If the Work Costs do not exceed the Construction Allowance, and any
Construction Allowance remains unused six (6) months after the Commencement
Date, then the unused balance of the Construction Allowance shall be forfeited.

Retention to Tenant or Tenant's Contractors unless and until Tenant or Tenant's
Contractor furnishes Landlord with:
