ITEM 1.  BUSINESS.

     DCH Technology, Inc., a Colorado corporation ("DCH" or the "Company"),
licenses, manufactures and markets state-of-the-art technologies involving
hydrogen-related products, primarily hydrogen gas detectors and fuel cells.

History
- -------

     DCH was formed in November 1994 as a partnership between David P. Haberman,
DCH's Vice President of Technology and Planning and Chairman of the Company's
Board of Directors, and David A. Walker, the Company's President and a member of
the Board of Directors.  DCH's initial strategy was to assist a small
engineering company in Marina Del Rey, California in the manufacturing and sale
of aircraft thermocouples based on the engineering company's design and
development work.

     DCH initially established offices in Sherman Oaks, California in December
1994. The Company was incorporated in California in January 1995.

     By mid-1995, the Company had abandoned the thermocouple business when the
local engineering company's design was found to have irrecoverable flaws.
Management of DCH then re-directed its efforts toward the commercialization of a
hydrogen gas detector developed and patented by Sandia National Laboratories
("Sandia") in Albuquerque, New Mexico.  From this time until mid 1997, the
Company funded itself primarily through research contracts and the resale of
aerospace equipment.

     After investigating the hydrogen energy industry and related technologies,
management of DCH decided to pursue the licensing of the Sandia patent.  In
April 1996, the Company entered into a license with Sandia and began to
concentrate on the production and qualification of the hydrogen sensors.  DCH
commenced initial pre-production and qualification of the hydrogen sensors in
February 1997, and continued redesign of the sensors to improve performance and
reduce costs.

     In May 1997, all of the outstanding capital stock of DCH was acquired by
Connection Sports, Inc., a publicly traded Colorado corporation ("CSI") in
exchange for the issuance of 6,000,000 shares of CSI common stock.   The
survivor was CSI, and its name was changed to DCH Technology, Inc. This stock
exchange transaction is treated as an acquisition by the Company of the net
tangible book value of the assets of CSI, at the date of the acquisition.  In
this Registration Statement, the terms "DCH" or "the Company" refers to DCH
Technology, Inc., a Colorado corporation, and DCH Sensors Corp., its wholly
owned California subsidiary.  DCH is currently traded on the Over-the-Counter
Bulletin Board under the symbol "DCHT".

                                       2

     DCH expanded its offices and moved to Valencia, California in June 1998.
This relocation allowed the Company to set up offices, manufacturing and
engineering areas, including a design and engineering laboratory, a test and
calibration laboratory and a manufacturing/assembly area. DCH's offices are
located at 27811 Avenue Hopkins #6, Valencia, California 91355; its telephone
number is (661) 775-8120. It also has a Web site, located at
http:\\www.dcht.com.

General / Products
- ------------------

     DCH licenses, manufactures and markets state-of-the-art technologies
focusing on hydrogen-related products.  The Company specializes in licensing and
converting new ideas and technologies into state-of-the-art products.  To date,
DCH has licensed three technologies involving hydrogen gas sensors and one
concerning fuel cells.

     Hydrogen Gas Sensors
     --------------------

     The Company's sensors are used for detection of hydrogen, the most
plentiful element on the earth.  Hydrogen is one of two major elements of water,
which covers over 60% of the planet.  It appears in different forms in plants,
animals, fossil fuels and a wide range of chemical compounds.  Hydrogen is a
combustible, odorless and colorless gas that is widely used in industrial,
commercial and medical applications.  When hydrogen burns, it generates only
energy and water, and thus is a clean non-polluting fuel.  The Company believes
that in the future, hydrogen may replace fossil fuels in both electrical power
generation and as the fuel of choice for the automotive industry.

     Hydrogen is also the key component in the manufacture of chemicals,
especially ammonia and methanol.  It is used in large quantities in refineries
for manufacturing gasoline and heating oil, as well as to make fertilizers,
glass, refined metals, vitamins, cosmetics, semiconductor circuits, soaps,
lubricants, cleaners, margarine, peanut butter and rocket fuel.  DCH's sensors
act to monitor and measure the amount of hydrogen used in processes within these
and other industries.

     In addition to its uses, however, hydrogen carries certain dangers.
Hydrogen is explosive when it reaches an approximate four percent concentration
in air or oxygen (this is known as the "Lower Explosive Limit" or "LEL" of
hydrogen).  In order to avoid these explosions, it is necessary to monitor and
measure the concentration of hydrogen in areas of concern and to either sound
warnings as this danger point is approached or to activate control equipment
which results in the avoidance of hazardous situations.  DCH's sensors act to
alert, warn, measure and/or control the flow and use of hydrogen.

     Based on industry sources, DCH estimates that the total annual worldwide
sales of gas detectors amounted to approximately $1.09 billion in 1997.
Approximately one-half of these sales involved gas detectors for carbon
monoxide, hydrogen sulfide, ammonia, oxygen and hydrogen, with hydrogen
detectors comprising approximately 9.8% of total sales.

                                       3

     DCH's technologies have opened additional markets for hydrogen gas sensors.
For example, DCH's sensors have been sold to Westinghouse for installation in
the Leningrad Nuclear Power Plant as safety monitors, as they were the only
economically priced hydrogen gas sensors that could withstand the harsh
environment of a nuclear power plant.

     DCH has licensed certain sensor technologies from several sources, and is
currently developing products based on these technologies: the Robust Hydrogen
Sensor, the Thick Film Hydrogen Sensor and the Universal Gas Detector.  The
Company is also developing a Fiber Optic Hydrogen Sensor.

     The Robust Hydrogen Sensor.  The Robust Hydrogen Sensor technology was
     --------------------------
invented and patented (patent number 5,279,795) by the U.S. Department of Energy
("DOE") at Sandia in Albuquerque, New Mexico. The technology, an Applications
Specific Integrated Circuit ("ASIC"), was developed by Sandia for the U.S.
Department of Defense for a classified nuclear weapons application. After Sandia
had patented the technology, it was made available to the commercial market for
licensing. This process permits the U.S. government to receive royalties and
licensing fees for the technology without expending the resources required to
commercialize products.

     DCH licensed the Robust Hydrogen Sensor from Sandia in April 1996. The
Sandia license agreement, which expires on the earlier of January 1, 2015 or the
expiration of Sandia's patent rights, required DCH to pay an up-front license
fee, payable in three equal installments. All of these installments have been
paid. In addition to the license fee, DCH will pay a royalty to Sandia for every
ASIC sold (whether sold alone or installed in a device or system), subject to
certain minimum royalties. In 1998 and 1999, DCH paid royalties of $1,000 and
$8,000, respectively, to Sandia under the Sandia license agreement. No royalties
were earned in 1997.

     The Robust Hydrogen Sensor technology consists of an array of two hydrogen-
sensing elements: palladium-nickel ("PdNi") gate CMOS field effect transistors
("FETs") and PdNi resistors.  The threshold voltage of the FETs shifts in
response to the concentration of hydrogen in the surrounding environment,
detecting hydrogen in concentrations from approximately ten parts per million
("ppms") to one percent.  The PdNi resistors also change their resistance in
response to the concentration of ambient hydrogen, allowing sensing from about
one percent to 100% concentration.  The technology also includes a micro-
thermometer (temperature diode) and micro-heaters for maintaining on-chip
temperature control and other chip functions.  In addition, the heaters are used
to temporarily heat the chip to "boil" off hydrogen molecules, which may stick
to the palladium, thus freeing the sensor for repeated use.

     The Sandia license agreement defines two fields of use for the licensed
technology.  The first field of use, covering the petrochemical, energy, waste
management, environmental and manufacturing industries, is exclusive to DCH
through

                                       4
<PAGE>

April 24, 2001. After that date, the license in this field becomes non-exclusive
for the remaining term of the license agreement. The second field of use covers
all other commercial applications and is non-exclusive.

     DCH offers the Robust Hydrogen Sensor technology in three basic forms.  The
first, an integration kit, is used for installation into customized systems as
leak detectors and measurement devices.  The second form consists of a hand-held
unit, affording portability in hydrogen detection and measurement.  The third
form is a sensor system, a fixed installation arrangement for leak detection
and/or measurement in remote locations.  DCH anticipates that this third product
will have the ability to be remotely interrogated whenever desired, and may be
coupled with a modem or radio tag which could power the ASIC and send a reading
back to a computer or other equipment at another location.


                                       5
<PAGE>


     To date, DCH has received over $700,000 in orders for its Robust Hydrogen
Sensor products.  The largest of these was received in March 1998, when
Westinghouse Nuclear Products Division (Monroeville, Pennsylvania) placed an
order for a retrofit of the reactor and turbine areas of the Leningrad Nuclear
Power Plant (LNPP) in Russia.


                                       6

     Thick Film Hydrogen Sensor.  The Thick Film Hydrogen Sensor technology was
     --------------------------
invented and patented (under U.S. patent numbers 5,367,283 and 5,451,920) by the
U.S. DOE at Oak Ridge National Laboratory in Oak Ridge, Tennessee ("ORNL").  The
sensor, developed by Barbara Hoffheins and Robert Lauf of ORNL, relies on the
reversible solubility of hydrogen in palladium.

     DCH commenced the development of the Thick Film Hydrogen Sensor technology
from Lockheed Martin Energy Research ("LMER"), an ORNL contractor, in September
1996, pursuant to a Cooperative Research and Development Agreement ("CRADA")
(the "ORNL CRADA"). Under the ORNL CRADA, DCH has provided a business plan and
product definition for commercialization of the technology, while LMER continues
development efforts for certain products based on the technology. The ORNL
CRADA, which expires in September 1999, anticipates an aggregate expenditure, in
cash and in-kind, of $1,170,000.

     Concurrently with entering into the CRADA, DCM and LMER entered into a
license agreement. The LMER license grants DCH the sole commercial right and
license to manufacture, use, sell or offer for sale the products based on the
thick film hydrogen sensor technology in the following fields of use: (i)
production, storage and transportation of hydrogen for use in the generation of
power; (ii) use of hydrogen in fuel cells and high yield energy storage; and
(iii) safety applications in the chemical and petroleum industries.

     The license has an initial term of five years, with renegotiation for
renewal every five years thereafter. It provides for an initial license fee
(paid by DCH in September 1996) and royalties on sales of products incorporating
the thick film hydrogen sensor technology. To date, no revenues have been
generated from such sales; management of DCH anticipates that production of
products will commence in approximately 12 to 18 months.

     The sensor is fabricated with conventional thick film materials and methods
(primarily because of significant cost advantages).  The design consists of
several electronic compositions that are separately screen-printed and fired
onto an alumna substrate.  The key sensor composition is primarily composed of
palladium metal because of its documented affinity for hydrogen.  Changes in
hydrogen concentration in the palladium matrix correspond to changes in the
electrical resistance of the palladium and can be easily measured.

     Universal Gas Detector.  A patent application was filed for the Universal
     ----------------------
Gas Detector technology on March 27, 1998 (priority claimed by United States
Provisional Application 60/041,653).  DCH licensed the invention from Simon
Fraser University ("SFU") in Burnaby, British Columbia, Canada on July 28, 1998.
The technology is intended to selectively detect any reducing gas or oxidizing
gas and/or their vapors, and involves a detecting system that can be designed to
use any commercially available sensor head.

                                       7
<PAGE>

     The license grants DCH the exclusive right and license, for any use, to
make, have made, use, maintain, execute, copy, market, lease and sell products
based on the technology.

     The license term is from July 28, 1998 until the end of the term for which
patent rights are granted. It provides for an initial license fee (paid by DCH
in April 1998) and royalties on sales of products incorporating the universal
gas detector technology. To date, no revenues have been generated from such
sales; management of DCH anticipates that production of products will commence
in approximately 18 to 24 months.

     The technology consists of software and electronics, which can be set to
selectively detect any reducing gas or oxidizing gas (and/or their vapors) to
which it is exposed.  This involves a detecting system that can be designed to
use any commercially available sensor head.

     Fiber Optic Hydrogen Sensor  The Fiber Optic Hydrogen Sensor technology
     ---------------------------
was invented by the U.S. DOE at the National Renewable Energy Laboratory
("NREL") in Golden, Colorado. DCH, through Amerisen, a joint-venture with
Midwest Research Technology, Inc. ("MRT"), commenced development of the Fiber
Optic Hydrogen Sensor technology in May 1996 pursuant to a CRADA with NREL. The
NREL CRADA required NREL to have primary responsibility for design and
development of a prototype sensor, while Amerisen would develop and manufacture
a hydrogen detector test station and demonstrate the sensor to potential
customers. Each party would contibute in-kind support, valued at an aggregate of
$1,700,000. The NREL CRADA expires in September 1999. The parties are currently
negotiating a license for the Fiber Optic Hydrogen Sensor technology. There can
be no assurance that such a license can be negotiated on terms acceptable to
DCH.

     Fuel Cells
     ----------

     The fuel cell was invented by William Robert Grove in 1839.  A fuel cell is
a device that uses a fuel (usually hydrogen) to create electricity. The method
it uses to create the electricity is fairly simple:  Hydrogen is introduced to
one side of the fuel cell (known as the anode). The hydrogen atom is stripped of
its electron as it progresses through the cell. The electron goes through a
conductor to create an electrical current. At the other end, the hydrogen joins
up with oxygen and forms water (H2O).

     When a fuel cell is used it creates clean power (electricity) with pure
water as the only byproduct.  The amount of power that can be created is
significant. ONSI Corporation, one of DCH's competitors, has manufactured a fuel
cell delivering 200kW of power. Ballard Power Systems, another competitor of the
Company, makes fuel cells used in buses in the U.S. and Canada which generate
205 kW (275 HP).  Fuel cells are being considered for use to power electric
vehicles by many of the major automobile manufacturers.

     The fuel cell industry is generally considered to be in its infancy (even
though the basic technology is almost 160 years old), because fuel cells
historically have been large and extremely expensive to manufacture.  However,
with the interest and financing from government labs (like Los Alamos National
Lab) and private entities (like Daimler Benz), the fuel cell is quickly becoming
economically viable and physically practical.

     PEM Fuel Cell.   The Company believes that in addition to the
     -------------
transportation sector, fuel cells might be used in markets such as emergency
power supplies, medical

                                       8
<PAGE>

applications, and portable low-power sources. As a result of this belief, DCH is
working with Los Alamos National Laboratory in Los Alamos, New Mexico ("LANL")
to commercialize its Proton-Exchange-Membrane ("PEM") fuel cell -- a small,
stackable device (each unit is a little smaller than a baseball cap) that will
deliver low power (less than 50 to 500 watts) reliably and cleanly. The current
configuration of the PEM fuel cell is not powerful enough to operate an
automobile, but the Company believes that it can provide enough power for people
in third world countries or in an emergency situation or other venue where no
power is present to operate such items as small medical equipment, communication
devices and camping equipment.

     The PEM fuel cell technology, relating to annular feed air breathing fuel
cell stacks, was invented and patented (under U.S. patent numbers 5,514,486 and
5,595,834) by the U.S. DOE at LANL. The fuel cell is designed to provide clean,
economic low power (from less than 50W to 5kW).

     DCH commenced development of the PEM fuel cell technology with LANL in
March 1999, pursuant to a CRADA (the "LANL CRADA"). Under the LANL CRADA, DCH
has provided a business plan and product definition for commercialization of the
technology, while LANL continues development efforts for 50W and 300W fuel cells
based on the technology. The LANL CRADA for the PEM fuel cell technology expires
in October 2000 and contemplates aggregate development expenditures (in cash and
in-kind) of $1,200,000.

      In connection with the LANL CRADA, DCH received two licenses for the PEM
fuel cell technology.  The first license grants DCH the exclusive license to
make, have made, use, import, sell and offer to sell the products based on the
patented technology (with sublicense rights) in the fields of use of
power generation for marine, aerospace, military, portable and remote-area
applications.  This exclusive license commenced in March 1999 and continues
until the expiration of the last patent on the technology.

     The exclusive license agreement provides for an up-front fee (paid by DCH
in March 1999) and annual license fees due on January 31st of each year of the
term of the exclusive license; these fees will be credited against royalties on
net sales of the fuel cells and other payments (such as sublicense fees).

     The second license grants DCH the non-exclusive license to make, have made,
use, import, sell and offer to sell the products based on the patented
technology (with sublicense rights) in the all fields of use except power
generation for marine, aerospace, military, portable and remote-area
applications.  The nonexclusive license commenced in March 1999 and continues
until the expiration of the last patent on the technology.

     The nonexclusive license agreement provides for an up-front fee (paid by
DCH in March 1999) and annual license fees due on January 31st of each year of
the term of the nonexclusive license; these fees will be credited against
royalties on net sales of the fuel cells and other payments (such as sublicense
fees).

     To date, no revenues have been generated from sales of fuel cells pursuant
to either the exclusive or nonexclusive licenses; management of DCH
anticipates that production of products will commence in approximately 12 to 18
months.

Marketing and Sales
- -------------------

     Hydrogen Sensors.  DCH has devised a marketing strategy for its hydrogen
     -----------------
sensors, and is currently in the process of implementing this strategy.  The
Company's strategy involves three components:  establishing DCH in the "hydrogen
community", comprised of trade groups such as the National Hydrogen Association,
the California Hydrogen Business Council and the Congressional Hydrogen
Technical Advisory Panel; establishing a coalition with the insurance industry
to require use of hydrogen detection systems; and using commissioned independent
sales representatives specializing in particular industries to sell the
Company's products.

     The strategy differs in each of DCH's target markets:  for example, in the
government/aerospace industries, DCH has utilized contacts with NASA to test its
sensors on certain aircraft engines.   Its continuing strategy includes
additional testing on engines, and installation of the sensors at various NASA
sites.  In the energy industry, DCH intends to participate in the creation and
refinement of the various codes and standards governing sensor systems as well
as to persuade insurance companies to promote the use of hydrogen sensors as
safety devices.  To date, DCH has participated in the associations listed above
and has contracted with companies including Westinghouse to provide hydrogen
sensors.  DCH's marketing strategy in the petrochemical industry involves the
introduction of sensors on a test basis to oil refineries through the Company's
pipe corrosion detection feature, a relatively new field of use.  DCH also
believes that refineries will recognize the value of its hydrogen sensors as a
cost-saving safety device.

     As part of its overall business plan, the Company has entered into
strategic partnerships with several organizations. The Company believes that
strategic partnerships are a key to future growth, especially in the hydrogen
gas detection and measurement business. The Company has identified 34 industries
where hydrogen sensors are used. By creating alliances with value added
resellers ("VARs") and distributors, the Company anticipates that it will be
able to penetrate multiple markets and realize higher sales volumes.

    In addition, the Company has made alliances with multiple transformer gas
analysis companies, which are testing DCH equipment for use in transformer
cooling oil.  These Companies may become VARs of DCH equipment based upon
qualification of DCH sensors in test procedures.

     On January 21, 1999, the Company announced the signing of a distribution
agreement with Horiba, Ltd., an international gas analyzer company. The
distribution agreement permits Horiba to distribute and sell products in Japan
based on the Robust Hydrogen
                                       10
<PAGE>

Sensor technology, utilizing both the DCH Hand Held Unit design and integrating
DCH electronics into a Horiba gas analyzer. The Horiba distribution agreement
has a term of one year, but will be automatically renewed for a five-year term
if Horiba sells 50 of such products during such year.

     The Company plans to use distributors to market its products overseas and
currently has agreements with ten distributors worldwide for the Robust Hydrogen
Sensor product line.

     DCH also has increased its visibility by providing presentations at
national and international conferences advocating the use of hydrogen sensors.
The Company has also participated in the formation of a coalition to provide
insurance industry risk assessments.

     Fuel Cells.  The Company has developed a marketing plan for its fuel cell
     ----------
product line, targeting certain domestic and international markets.  The plan
has not been fully implemented, however, because the product is still in
development. Management believes that the single largest barrier to market
acceptance of its fuel cells will be the lack of market knowledge about the
benefits of fuel cells. With this in mind, the Company has embarked on a market
education program. The Company has manufactured several prototype demonstration
units of its fuel cells and has successfully operated hardware at trade shows
and conferences. In addition, Company personnel have spoken at conferences about
the fuel cell product. As the Company nears the commercial introduction of its
fuel cells, these educational activities will continue to increase.

Research and Development
- ------------------------

     Management of DCH believes that continuing research and development of its
licensed technology is critical to penetrating existing markets through superior
product features, opening new markets and obtaining a competitive advantage.
Due to its limited resources, DCH currently conducts its research and
development activities with strategic partners:  sensor development in
connection with federal research laboratories such as ORNL; applications
development in conjunction with DCH's field representatives; and advanced
systems designs for specialized industries with customers.

     To date, a significant portion of DCH's research and development has
occurred through CRADAs with the U.S. Department of Energy: the ORNL CRADA, the
LANL CRADA and the NREL CRADA. See "Business - General/Products".

     During the years ended December 31, 1997 and 1998, the Company expended
$59,484 and $1,810,185 respectively, on Research and Development. None of these
expenses were funded by the Company's customers.

Manufacturing
- -------------

     At the present time, the Company's Robust Hydrogen Sensor product line
constitutes the only products of the Company in production.  DCH subcontracts
specialty processes relating to the Robust Hydrogen Sensor product line to
several major manufacturers.  Semiconductor wafer production for the Company's
hydrogen sensor element occurs at Allied Signal's Microelectronics and
Technology Center in Columbia,

                                       11
<PAGE>

Maryland. Electronic circuit boards are fabricated by International Circuits and
Components, Inc. (ICCI) in Anaheim, California. Housings and other hardware are
fabricated by various small manufacturers. DCH conducts final assembly,
calibration and finished product testing of the sensors. To date, DCH has not
experienced any interruption in the manufacture of its products, and anticipates
that sources for each of its subcontracting activities will be readily
available. The Company is currently in the initial production phase and
anticipates going into full production within a year.

Backlog
- -------

     The commercial order backlog for DCH's products at June 30, 1999 was
$267,195, compared with $271,043 at June 30, 1998.  Since the Company generally
ships its products within the same quarter that it receives a purchase order
from the customer for such products, the Company believes that its backlog at
any particular time is generally not indicative of the level of future sales.

Competition
- -----------

     DCH competes in both the hydrogen sensor and fuel cell markets.  The
hydrogen sensor market is extremely competitive, with several manufacturers
competing for acceptance.  Most of DCH's competitors have far greater financial,
marketing and manufacturing resources than DCH by virtue of their being long
established in the field.  The attributes upon which competition is based are
primarily reliability, ease of use, product support, response speed, accuracy
and price.  Management of DCH believes that its hydrogen sensor products offer
several advantages, including a faster reaction time of less than two seconds
near the LEL (current detectors may take as long as two minutes to return a
reading) and extended sensor life.  In addition, the Company's sensors are
hydrogen-specific and therefore not prone to false readings, and operate in
hostile environments such as radioactive areas.  Finally, the sensors indicate a
complete range of hydrogen presence, similar to that offered by mass
spectrometers but at a much lower cost.

     Competition in the fuel cell industry is comprised primarily of companies
that do research and testing but have no foreseeable path to commercialization.
DCH believes its simple, passive technology will provide significant economic,
utilization and performance advantages.  Management believes the Company's fuel
cell has significant advantages over existing low power fuel cells in
development at other companies.  These advantages include a smaller size and
weight, no moving parts (it is a completely passive device), low cost and
simplicity of design.

Government Regulation
- ---------------------

     The Company is permitted to export its hydrogen sensors without
restriction, as the U.S. Department of Commerce, Bureau of Export Control has
assigned the sensor an ECCN of EAR99.

                                       12
<PAGE>

     DCH's production of hydrogen fuel cells will be subject to various federal,
state and local laws and regulations relating to, among other things, land use,
safe working conditions, handling and disposal of hazardous and potentially
hazardous substances and emissions of pollutants into the atmosphere.  To date,
DCH believes that it has obtained all necessary government permits and has been
in substantial compliance with all of these applicable laws and regulations.

Employees
- ---------

     As of June 30, 1999, the Company employed 13 people on a full-time basis,
consisting of 7 people in engineering/development/manufacturing, 4 in
administration and 2 in sales/customer service.  DCH's employees are not
represented by a labor union, and it has experienced no work stoppages.  The
Company believes that its employee relations are good.  The loss of key
employees could cause delays in completing contracted work and research and
development and commercialization activities.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

General
- -------

     DCH licenses, manufactures and markets state-of-the-art technologies
involving hydrogen-related products, primarily hydrogen gas detectors and fuel
cells. The Company currently obtains its funding from private placements of
equity securities and product sales. The Company commenced initial production of
its first product line, the Robust Hydrogen Sensor product line, in November
1998. As production activity increases, the production facilities are more fully
utilized and the Company fully implements its marketing strategies, management
expects revenues from sales of product to increase in proportion to funding from
continued equity placements.

Results of Operations
- ---------------------

Six Months Ended June 30, 1999 Compared with Six Months Ended June 30, 1998
- ---------------------------------------------------------------------------

                                       13
<PAGE>

For the six months ended June 30, 1999, the Company had sales of $216,773
compared to sales of $24,000 for the six months ended June 30, 1998. The
increased sales in 1999 were due primarily to the Company's introduction of its
Robust Hydrogen Sensor product line in November 1998. In accordance with the
growth in sales, the cost of products sold increased to $142,878 for the six
months ended June 30, 1999 compared to $5,720 for the comparable period in 1998.
Gross profit was $73,895 for the six months ended June 30, 1999 compared to
$18,280 for the six months ended June 30, 1998, also reflecting the increased
sales.

Selling, general and administrative expenses were $1,033,784 for the six months
ended June 30, 1999, compared to $1,281,448 for the comparable period in 1998.
Substantially all of the selling, general and administrative expenses in the
first two quarters of 1999 were derived from the ramp up required to
commercialize and introduce the Robust Hydrogen Sensor product line, while the
1998 expenses primarily reflected stock-based awards issued by the Company to
employees and non-employees in consideration of services or goods provided.

Depreciation and amortization increased to $24,014 for the six months ended June
30, 1999, compared to $7,518 for the six months ended June 30, 1998, due to
purchases by the Company of equipment for its operations.

The Company expended $319,498 on research and development during the six months
ended June 30, 1999 compared to expenditures of $610,294 for the comparable
period in 1998. The decrease was due to the movement of the Robust Hydrogen
Sensor product line from the research and development phase to initial
production.

As a result of the foregoing factors, the Company's net loss decreased to
$1,303,357 for the six months ended June 30, 1999, from $1,879,072 for the six
months ended June 30, 1998. Due to an increase in the number of shares
outstanding during the period, the net loss per share decreased to $.10 for the
six months ended June 30, 1999 from $.22 for the comparable period in 1998.

Year Ended December 31, 1998 Compared With Year Ended December 31, 1997
- -----------------------------------------------------------------------

     For the year ended December 31, 1998, the Company reported sales of
$207,580, compared to sales of $89,751 in the prior year.  Sales in both years
consisted primarily of research projects performed by the Company for the
benefit of third parties.  The increase in sales was due primarily to an
increase in the number of projects undertaken by the Company, but also reflected
the introduction of the Company's Robust Hydrogen Sensor product line in
November 1998.  Cost of sales for the year ended December 31, 1998 equaled
$66,480; the Company did not incur costs of sales for the prior year, as sales
in 1998 consisted solely of research projects with no hardware deliverables.

     Selling, general and administrative expenses were $2,880,897 for the year
ended December 31, 1998, as compared to $208,026 for the year ended December 31,
1997.  The substantial increase was composed of several factors reflecting the
Company's ramp

                                       14
<PAGE>

up of operations: stock-based awards issued by the Company during fiscal 1998 to
employees and non-employees in consideration of services or goods provided prior
to or during that year, an increase in the number of employees, the Company's
move to larger facilities and the commencement of manufacturing operations.

     The Company incurred depreciation and amortization expenses of $31,857 in
the year ended December 31, 1998 compared to $8,304 in the prior year, due to
purchases by the Company of equipment for its operations.

     Research and development expenditures in the year ended December 31, 1998
were $1,810,185, compared to $ 59,484 in 1997.  The increase in 1998 was
primarily due to the ramp up in the development of several systems for the
Robust Hydrogen Sensor product line and the research and development of the
Company's thick film hydrogen sensor, universal gas detector and fuel cell
products.

     Due to the factors set forth above, the Company incurred a net loss of
$4,577,656 in 1998 compared with $185,157 in 1997.  The net loss per share
increased to $.48 for the year ended December 31, 1998 compared to $.04 for the
year ended December 31, 1997.

Liquidity and Capital Resources
- -------------------------------

     To date, the Company has funded its operations primarily through private
placements of equity securities and secondarily through product sales and loans
from officers and major shareholders. Such placements generated net proceeds of
$900,356 during the six months ended June 30, 1999, $1,310,729 for the year
ended December 31, 1998 and $81,500 during the year ended December 31, 1997. At
June 30, 1999, the Company had a working capital deficit of $164,885, including
$38,531 cash, compared to a working capital deficit of $656,891, including
$344,417 cash at June 30, 1998.

     The Company's cash increased by $662 during the year ended December 31,
1998.  The increase was due primarily to financing activities, which provided
$1,478,021 to the Company in 1998.  Operating activities in 1998 utilized
$1,228,371 of cash, and investing activities utilized $248,988 during the same
period.

     The Company remains dependent upon its ability to obtain outside financing
through the issuance of additional securities until it achieves sustained
profitability through increased sales.  Management believes that the Company
will require significant resources in 1999, principally to fund the Company's
working capital needs to support the commercialization of the Company's hydrogen
sensor and fuel cell products and continuing research and development efforts.
The Company expects to generate the necessary resources for its 1999 business
plan through a combination of the contribution from sales of its products and
additional private placements of equity securities.  No assurances can be given,
however, that the Company will be able to obtain such additional resources.

                                       15
<PAGE>

     If the Company is unsuccessful in generating anticipated resources from one
or more of the anticipated sources and is unable to replace any shortfall with
funding from another source, the Company may be able to extend the period for
which available resources would prove adequate by deferring the satisfaction of
various commitments or otherwise scaling back operations.  If the Company were
unable to generate the required resources, its ability to meet its obligations
and to continue its operations would be adversely affected.  The Company's
financial statements have been prepared under the assumption of a going concern.
Failure to generate required resources and to achieve sustained profitability
would have an adverse effect on the financial position, results of operations,
cash flows and prospects of the Company and ultimately on its ability to
continue as a going concern.

Year 2000 Readiness Disclosure
- ------------------------------

     The Year 2000 ("Y2K") issue refers to the potential for failure of computer
systems that use two digits rather than four digits to identify the applicable
year.  This raises the possibility that some systems may recognize the year 2000
as the year 1900, which may result in system failure, miscalculations, loss of
data, etc.

     In 1998, the Company contracted with a Y2K consultant who, in concert with
Company personnel and one of the Company's aerospace customers, conducted a
comprehensive evaluation of all its systems, including the internal network,
local micro-computers, test equipment, financial systems and software imbedded
in its products.  Based on this testing, the Company was found to be Y2K
compliant in all of its product and internal systems.  The Company has also
received assurances from the suppliers of the software it employs that such
software is Y2K compliant, and intends to obtain assurances that any computer
software and hardware purchased in 1999 is Y2K compliant.  The Company does not
believe that its insistence upon Y2K compliant hardware or software will
materially increase the cost thereof.

     The Company currently has limited information regarding the Y2K compliance
status of its principal customers and suppliers of goods and services.  In
informal communications with all of its suppliers, the Company has been assured
that such suppliers' computer systems are Y2K compliant; however, it has not
received formal guarantees of such compliance.  If any principal suppliers of
the Company lack systems that are Y2K compliant or programs that provide
reasonable assurance that such systems will be Y2K compliant well before the end
of 1999, the Company will attempt to identify and establish relations with
alternative suppliers who have Y2K compliant systems.  There can be no assurance
that the Company would be successful in locating such new suppliers.

     The Company sells its products for integration in other systems developed
by its customers.  While management believes those systems to either be Y2K
compliant or committed to be Y2K compliant by January 1, 2000 (based the
Company's survey of those customers), the Company has no control over the
ability and internal commitment

                                       16
<PAGE>

of such customers to meet this goal. Therefore, the possibility remains that
some DCH products may be integrated with other companies' non-Y2K compliant
equipment.

     The Company believes that the costs associated with monitoring Y2K
compliance by suppliers and customers and dealing with any non-compliance will
not be material.  The failure of the Company or any of its principal customers
or suppliers to become Y2K compliant in a timely manner could have a material
adverse effect on the Company's business, financial condition, results of
operations and cash flow.

ITEM 3.  PROPERTIES.

     The Company's principal executive, administrative, and engineering
operations are located in two leased facilities totaling  6,700 square feet in
Valencia, California.  The main office is occupied under a lease expiring on May
31, 2001.  The production facility is in a separate building nearby
(approximately 150 yards from the main office) occupied under a lease expiring
on April 30, 2002.  The Company leases approximately 3,300 square feet in
Madison, Wisconsin where it conducts research and development on the fuel cell
product and where it plans to expand into limited production.  This lease
expires on April 30, 2002.  The Company also occupies a small sales office
(approximately 150 square feet) in Washington, DC under a month-to-month lease.
Management considers that the current facilities are adequate for the present
level of operations and that additional office and factory space is available in
the immediate vicinity.

Director Compensation
- ---------------------

     Members of the Board of Directors did not receive cash compensation in 1998
for their services to DCH in such capacity.  However, in 1998 each Director
received 30,000 shares of the Company's restricted Common Stock for their
service as Board members.  In addition, each Board member was granted in 1998
options to purchase 50,000 shares of the Company's Common Stock, at an exercise
price of $0.25 per share, expiring in 2008. The options vested immediately upon
the date of grant.

     Effective in 1999, compensation for members of the Board of Directors
(regardless of whether such members are employees of the Company) will be as

shares of which were outstanding at June 30, 1999, and 5,000,000 shares of

Common Stock
- ------------

     The holders of Common Stock are entitled to one vote per share on all
matters on which the holders of Common Stock are entitled to vote and do not
have cumulative voting rights in the election of directors. Holders of Common
Stock are entitled to dividends when, if and as may be declared by the Board of
Directors out of funds legally available therefor.  Under the Colorado
Corporations Code, DCH may declare and pay dividends only out of its surplus, or
if there shall be no such surplus, out of its net profits for the fiscal year in
which the dividend is declared or the preceding year.  In the event of the
liquidation, dissolution or winding up of the Company, holders of shares of
Common Stock are entitled to share ratably in the assets, if any, available for
distribution after payment of all creditors and the liquidation preferences on
any outstanding shares of Preferred Stock.  Holders of Common Stock have no
preemptive rights to subscribe for any additional securities of any class which
the Company may issue, nor any conversion, redemption or sinking fund rights.
The rights and privileges of holders of Common Stock are subject to the
preferences of any shares of Preferred Stock that the Company may issue in the
future.

Preferred Stock
- ---------------

     The Company may issue shares of Preferred Stock in one or more classes or
series within a class as may be determined by the Company's Board of Directors,
who may establish, from time to time, the number of shares to be included in
each class or series, may fix the designation, powers, preferences and rights of
the shares of each such class or series and any qualifications, limitations or
restrictions thereof, and may increase or decrease the number of shares of any
such class or series without any further vote or action by the shareholders.
Any Preferred Stock so issued by the Board of Directors may rank senior to the
Common Stock with respect to the payment of dividends or amounts upon
liquidation, dissolution or winding up of the Company, or both.  In addition,
any such shares of Preferred Stock may have class or series voting rights.
Moreover, under certain circumstances, the issuance of Preferred Stock or the
existence of the unissued Preferred Stock may tend to discourage or render more
difficult a merger or other change in control of the Company.

Transfer Agent and Registrar
- ----------------------------

     The Transfer Agent and Registrar for the Company's Common Stock is Holladay
Stock Transfer, Inc., in Phoenix, Arizona.

ITEM 1.  MARKET PRICE OF AND DIVIDENDS ON THE REGISTRANT'S
         COMMON EQUITY AND OTHER SHAREHOLDER MATTERS.

     Since May 16, 1997, the Company's Common Stock has been traded on the OTC
Bulletin Board under the symbol "DCHT".  The following table sets forth, for the
periods indicated, the high and low bid prices for the Common Stock as reported
by the OTC Bulletin Board.  The following quotations should not be construed to
imply that an established trading market exists for the Common Stock; trading to
date has been sporadic.

</TABLE>

     The market price for the Company's Common Stock has historically been
volatile.  Significant volatility in the market price of shares of the Company's
Common Stock may arise in the future due to factors such as the Company's
developing business, historic losses and relatively low price per share.  In
addition, future announcements concerning the Company or its competitors may
have a significant impact on the market price of the Common Stock.  Such
announcements might include financial results, the results of testing,
technological innovations, new commercial products, changes to government
regulations, developments concerning proprietary rights, or litigation.  As long
as there is only a limited public market for the Common Stock, the sale of a
significant number of shares of Common Stock at any particular time could be
difficult to achieve at the market prices prevailing immediately before such
shares are offered, and the offering of a significant number of shares of Common
Stock at one time could cause a severe decline in the price of the Common Stock.

investment and not with a view to the distribution thereof; and that the
purchasers did not intend to sell or otherwise dispose of all or any part of the

predetermined event. Each purchaser also agreed that he or she would offer or
resell shares only if the shares were registered under the Securities Act or an
exemption from such registration was available. No advertising or public
solicitation was used in the placement. The Company placed a restrictive legend
on the certificates representing the shares and placed "stop transfer"

ITEM 5.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Article V of the Company's Bylaws require the Company to indemnify, to the
fullest extent allowed by the Colorado Business Corporation Act (the "CBCA"),
any person who serves or who has served at any time as a director or an officer
of the Company, and any director or officer who, at the request of the Company,
serves or at any time has served as a director, officer, partner, trustee,
employee, or agent of any other foreign or domestic corporation or of any
partnership, joint venture, trust, other enterprise or employee benefit plan,
against any and all liabilities and reasonable expenses incurred in connection
with any claim, action, suit, or proceeding to which such director or officer is
made a party, or which may be asserted against him, because he is or was a
director or an officer.  This Article also provides that directors of the
Company shall not be liable to the Company or any of its shareholders for
monetary damages caused by a breach of fiduciary duty as a director.

     Sections 7-109-102 and 103 of the CBCA authorize the indemnification of
directors and officers against liability incurred by reason of being a director
or officer and against expenses (including attorney's fees) judgments, fines and
amounts paid in settlement and reasonably incurred in connection with any action
seeking to establish such liability, in the case of third-party  claims, if the
officer or director  acted in good faith and in a manner he reasonably  believed
to be in or not opposed to the best interests  of the corporation, and in the
case of actions by or in the right of the corporation, if the  officer or
director acted in good faith and in a manner he reasonably believed to be in or
not opposed to the best interest of the corporation and if such officer or
director shall not have been adjudged liable to the corporation, unless a court
otherwise determines.  Indemnification is also authorized with respect to any
criminal action or proceeding  where the officer or director had no reasonable
cause to believe his conduct was unlawful.

     The above discussion of the Company's Bylaws and the CBCA is only a summary
and is qualified in its entirety by the full text of each of the foregoing.

     Directors and officers of the Company and its subsidiaries are covered by
an insurance policy that insures them against certain losses, liabilities and
expenses.  The annual aggregate liability limit under the policy is $2,000,000.
The policy contains numerous exclusions, including exclusions for personal
profit, libel and slander and certain environmental liabilities.

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


The Stockholders and Board of Directors of
DCH Technology, Inc.



We have audited the accompanying consolidated balance sheet of DCH Technology,
Inc. and Subsidiary as of December 31, 1998 and the related consolidated
statements of operations, stockholders' equity (deficit) and cash flows for the
years ended December 31, 1998 and 1997. These consolidated financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these consolidated financial statements based on our
audits.

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

In our opinion, the consolidated financial statements present fairly, in all
material respects, the financial position of DCH Technology, Inc. and Subsidiary
at December 31, 1998 and the results of its operations and its cash flows for
the years ended December 31, 1998 and 1997 in conformity with generally accepted
accounting principles.

The accompanying consolidated financial statements have been prepared assuming
that the Company will continue as a going concern. As shown in the financial
statements, the Company incurred significant losses since inception, and has an
accumulated deficit. These conditions raise substantial doubt about its ability
to continue as a going concern. Management plans regarding those matters are
described in Note 12. The consolidated financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

   INFORMATION AS TO THE PERIODS ENDED JUNE 30, 1999 AND 1998 IS UNAUDITED

1.   NATURE OF THE BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES

     Organization and business
     -------------------------

     DCH Technology, Inc. (the Company), formerly Connection Sports
     International, Inc., a Colorado corporation, was incorporated on February
     23, 1996. The Company is engaged in the business of specializing in
     licensing and converting new ideas and technology into state-of-the art
     products. Currently, the Company has licensed technologies related to
     hydrogen sensing and fuel cells and is in the initial stages of limited
     production and limited sales.

     Business Recapitalization and Restatement
     -----------------------------------------

     On May 28, 1997, all of the outstanding capital stock of DCH Technology,
     Inc. was acquired by Connection Sports International, Inc. (CSI). In
     connection with this transaction, all of the shares of DCH Technology,
     Inc., were exchanged for 6,000,000 shares of CSI with CSI as the surviving
     corporation, which changed its name to DCH Technology, Inc. This stock
     exchange transaction is treated as an acquisition by the Company of the net
     tangible book value of the assets of CSI, at the date of the acquisition.
     Operating results of CSI for all periods prior to the date of its
     acquisition were not included in the operating results of the Company since
     such reverse merger is not treated as a pooling of interest for accounting
     purposes. DCH Technology, Inc. was engaged in the business of specializing
     in licensing and converting new ideas and technology into state-of-the art
     products.

     Principles of Consolidation
     ---------------------------

     The consolidated financial statements include the accounts of DCH
     Technology, Inc. and its wholly owned subsidiary. Significant intercompany
     accounts have been eliminated.

     Revenue Recognition
     -------------------

     Revenue from product sales is generally recognized at the time the product
     is shipped, with provisions established for priced protection programs and
     estimated product returns. Upon shipment, the Company also provides for the
     estimated cost that may be incurred for product warranties and post-sale
     support, if any. Service revenue is recognized over the contractual period
     or as services are rendered and accepted by the customer.

     Product Warranty
     ----------------

     The Company has calculated a reserve for the estimated cost of fulfilling
     its warranty obligation for products sold. The amount of such warranty
     obligation has been calculated based upon the expected returns for the
     various products lines and average estimated repair cost. Management does
     not deem the reserve to be significant to the accompanying financial
     statements, and therefore, a reserve has not been recorded at December 31,
     1998 and June 30, 1999.

   INFORMATION AS TO THE PERIODS ENDED JUNE 30, 1999 AND 1998 IS UNAUDITED

1.   SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES (continued)

     Allowance for Doubtful Accounts
     -------------------------------

     No allowance for doubtful accounts has been provided, as it is the
     management's belief that receivables are fully collectible at December 31,
     1998 and June 30, 1999.

     Recently Issued Accounting Pronouncements
     -----------------------------------------

     In 1997, the Financial Accounting Standards Board (FASB) issued Statements
     No. 130, "Reporting Comprehensive Income", and No. 131, "Disclosures about
     Segments of an Enterprise and Related Information". The Company's adoption
     of these statements had no material impact on the accompanying financial
     statements.

     Year 2000 Issues
     ----------------

     Many computers and other equipment with embedded chips or microprocessors
     may not be able to appropriately interpret dates after December 31, 1999,
     because such systems use only two digits to indicate a year in the date
     field rather than four digits. If not corrected, many computers and
     computer applications could fail or create miscalculations, causing
     disruptions to the Company's operations. In addition, the failure of
     customer and supplier computer systems could result in interruption of
     sales and deliveries of key supplies or utilities. Because of the
     complexity of the issues and the number of parties involved, the Company
     cannot reasonable predict with certainty the nature of likelihood of such
     impacts.

     The Company is actively addressing this situation and anticipates that it
     will not experience a material adverse impact to its operations, liquidity
     or financial condition related to systems under control. The Company is
     addressing the Year 2000 issue in four overlapping phases: (i)
     identification and assessment of all critical software systems and
     equipment requiring modification or replacement prior to 2000; (ii)
     assessment of critical business relationships requiring modification prior
     2000; (iii) corrective action and testing of critical systems; (iv)
     development of contingency and business continuation plans to mitigate any
     disruption to the Company's operations arising from the Year 2000 issue.

     The Company is in the process of implementing a plan to obtain information
     from its external service providers, significant suppliers and customer,
     and financial institutions to confirm their plans and readiness to become
     Year 2000 compliant, in order to better understand and evaluate how their
     Year 2000 issues may affect the Company's operations. The Company currently
     is not in a position to assess this aspect of the Year 2000 issues;
     however, the Company plans to take the necessary steps to provide itself
     with reasonable assurance that its service providers, customers and
     financial institutions are Year 2000 compliant.

     The Company is developing contingency plans to identify and mitigate
     potential problems and disruptions to the Company's operations arising from
     the Year 2000 issue. The total cost to achieve Year 2000 compliance is not
     expected to be material. Amounts spent to date have not been material.

   INFORMATION AS TO THE PERIODS ENDED JUNE 30, 1999 AND 1998 IS UNAUDITED

1.   SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES (continued)

     While the Company believes that its own internal assessment and planning
     efforts with respect to its external service providers, suppliers,
     customers and financial institutions are and will be adequate to address
     its Year 2000 concerns, there can be no assurance that these efforts will
     be successful or will not have a material adverse effect on the Company's
     operations.

     Inventories
     -----------

     Inventories are stated at the lower of cost or market using the first-in,
     first-out method (FIFO). Inventories consist of parts and assemblies that
     are included in the final product.

     Research and Development
     ------------------------

     Research and development expenditures are charged to operations as
     incurred.

     Property and Equipment
     ----------------------

     Property and equipment is stated at cost. The assets are being depreciated
     using the straight-line method over their estimated useful life of five to
     seven years.

     It is the policy of the Company to capitalize significant improvements and
     to expense repairs and maintenance.

     Deferred Revenue
     ----------------

     On January 15, 1997, the Company entered into an agreement with a
     California company for sale of a certain number of various hydrogen
     sensors. The sales agreement includes a provision of an initial payment of
     $30,000 when the first order is placed. As of December 31, 1998 and June
     30, 1999, the remainder of the initial payment was $28,800 and has been
     reflected as deferred revenue on the consolidated balance sheet at December
     31, 1998. On June 24, 1999 the Company received a pre-payment on a purchase
     order of $8,250. The total, $37,050, is reflected as deferred revenue on
     the consolidated balance sheet at June 30, 1999.

     Stock Based Compensation
     ------------------------

     The Company accounts for stock-based compensation as prescribed by
     Statement of Financial Accounting Standard (SFAS) Number 123, and has
     adopted its disclosure provisions. SFAS 123 requires pro forma disclosures
     of net income and earnings per share as if the fair value based method of
     accounting for stock based compensation had been applied.


     Loss Per Share
     --------------

     Loss per share of common stock is computed using the weighted average
     number of common shares outstanding during the period shown. Common stock
     equivalents are not included in the determination of the weighted average
     number of shares outstanding, as they would be antidilutive.

1.   SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES (continued)

     Statement of Cash Flows
     -----------------------

     For the purpose of the statement of cash flows, cash includes amounts "on-
     hand" and amounts deposited with financial institutions.

     Impairment of Long Lived Assets
     --------------------------------

     The Company evaluates its long lived assets by measuring the carrying
     amount of the asset against the estimated undiscounted future cash flows
     associated with them. At the time such evaluations indicate that the future
     undiscounted cash flows of certain long lived assets are not sufficient to
     recover the carrying value of such assets, the assets are adjusted to their
     fair values. No adjustment to the carrying value of the assets have been
     made.

     Use of Estimates in Preparation of Consolidated Financial Statements
     --------------------------------------------------------------------

     Management of the Company has made a number of estimates and assumptions
     relating to the reporting of assets, liabilities, revenue, expenses and
     disclosure of contingent assets and liabilities to prepare these financial
     statements in accordance with generally accepted accounting principles.
     Accordingly, actual results may differ from those estimates.

     Reclassification of Financial Statement Presentation
     ----------------------------------------------------

     Certain reclassifications have been made to the 1997 financial statements
     to conform with the 1998 financial statement presentation.

     Unaudited Interim Financial Statements
     --------------------------------------

     In the opinion of management, the unaudited interim financial statements
     for the six months periods ending June 30, 1999 and 1998 are presented on a
     basis consistent with the audited financial statements and reflect all
     adjustments, consisting only of normal recurring accruals, necessary for
     fair presentation of the results of such periods.

     2.  RELATED PARTY TRANSACTIONS

     Various advances from stockholders and advances from the Company to
     stockholders, occurred during the year ended December 31, 1998. As of
     December 31, 1998, the Company has a payable to stockholders in the amount
     of $180,359 and as of June 30, 1999, has a payable to stockholders in the
     amount of $128,725. Interest is accruing at a rate equal to the prime rate
     as published in the Wall Street Journal on the last day of the month. The

4.   INVESTMENT IN PARTNERSHIPS

     During the year ended December 31, 1998, the Company invested in two
     partnerships. The investments are accounted for in accordance with the
     provisions of Accounting Principles Board (APB) Opinion Number 18, Equity
     Method of Accounting for Investments in Common Stock. As the Corporation's
     ownership interest in all of the limited partnerships in the investment
     portfolio is more than 20% and less than or equal to 50%, the investment in
     the limited partnerships is accounted for using the equity method. Under
     this method, the investor adjusts the carrying amount of an investment for
     its share of the earnings or losses of the investee and reports the
     recognized earnings and losses in income.

     Dividends received from an investee reduce the carrying amount of the
     investment. The cost of the investments in limited partnerships at December
     31, 1998 and June 30, 1999, is as follows:

          Infrasoll LLC                          $           66,000
          Renewable Energies Group LLC                       33,000
                                                    ---------------
                                                 $           99,000
                                                    ===============

     No activity has occured in these partnerships since the initial investment.

     prior to repayment of the advance, the customer will provide shares to the
     Company as repayment of this advance at an equivalent of $10.00 per share
     or 33% discount to the IPO price, whichever is less.

7.   INCOME TAXES

     Income taxes are provided pursuant to SFAS No. 109 Accounting for Income
     Taxes. The statement requires the use of an asset and liability approach
     for financial reporting for income taxes. If it is more likely than not
     that some portion or all of a deferred tax asset will not be realized, a
     valuation allowance is recognized. Accordingly, as the realization and use
     of the net operating loss carryforward is not probable at December 31, 1998
     and June 30, 1999, the tax benefit of the loss carryforward has been
     offset by a valuation allowance of the same amount.

     The composition of deferred tax assets is as follows:

     License Agreements
     ------------------

     On April 24, 1996, the Company negotiated and executed a license agreement
     with Sandia Corporation (manager and operator of a federally-owned facility
     known as Sandia National Laboratories for the United States Department of
     Energy (DOE)), the owner of the rights to U.S. Patent 5,279,795 (a
     sensitive detector for hydrogen). Under the terms of the agreement, in
     exchange for a license fee, the Company was granted a limited nonexclusive
     right to make, have made or sell products under one or more claims of
     Sandia patent rights. The license fee is being amortized on a straight-line
     basis over the remaining life of the license agreement. In addition to the
     annual payments for the license, the Company has agreed to pay royalties,
     which is the larger of a minimum amount or a percentage of sales and to
     meet certain production and sales milestones during the term of the
     contract. The license expires on January 1, 2015.

     The Company entered into an agreement with Lockheed Martin Energy Research
     Corporation (manager of Oak Ridge National Laboratory for the U.S.
     Department of Energy) for a license fee the Company was granted the license
     for U.S. Patent 5,451,920 (Thick Film Hydrogen Sensor") and U.S. Patent
     Application S/N 08/445,325 ("Improved Thick Film Hydrogen Sensor"), on
     September 30, 1996. Under the terms of the agreement, the Company will be
     the sole licensee to manufacture, use, sell or offer for sale the products
     for a period of five years. The license fee is being amortized on a
     straight-line basis over the 5 year life of the contract. The contract also
     includes a provision for royalty payments which is the larger of a minimum
     amount or a percentage of net sales.

     Additionally, the Company entered into an agreement with Simon Fraser
     University on May 15, 1998, owner of the provisional patent rights to an
     invention called "Universal Gas Sensor", to be the exclusive licensee to
     make, have made, execute, copy, market, lease and sell licensed products
     during the term of the agreement. Under the terms of the agreement, in
     exchange for a license fee, the Company was granted the license for the
     patent to the "Universal Gas Sensor". The license fee is amortized on a
     straight-line basis over a 5 year life. The contract also includes a
     provision for royalty payments which is the larger of a minimum amount or a
     percentage of net sales.

     The total amortization expense related to the license agreements was $5,775
     and $1,400 for the years ended December 31, 1998 and 1997, respectively and
     $5,169 and $1,944 for the periods ended June 30, 1999 and 1998,

     and $11,000, respectively, and for the period ended June 30, 1999, and
     1998, was $20,500 and $9,000, respectively.

     Employment Agreements
     ---------------------

     The Company currently has employment agreements with each of David P.
     Haberman and David A. Walker, its Vice President, Technology and Planning,
     and President, respectively. Each employment agreement commenced on January
     1, 1995 and terminates on December 31, 2000, and provides for an annual
     salary currently set at $100,000. Neither of the employment agreements
     provides for additional payments upon a change in control.

12.  GOING CONCERN

     The Company has not had significant revenues and has experienced operating
     losses since inception primarily caused by its continued development and
     marketing costs. As shown in the accompanying financial statements, the
     Company incurred a net loss of $4,577,656 and $185,957 for the year ended
     December 31, 1998 and 1997, and as of December 31, 1998 has an accumulated
     deficit of $5,030,931. Those factors create an uncertainty and raise
     substantial doubt about the Company's ability to continue as a going
     concern. Management of the Company intends to pursue various means of
     obtaining additional capital. The financial statements do not include any
     adjustments that might be necessary if the Company is unable to continue as
     a going concern. Continuation of the Company as a going concern is
     dependent on the Company continuing to raise capital, developing
     significant revenues and ultimately attaining profitable operations.

The principal office of the Corporation in the State of California, shall be
located at 14241 Ventura Boulevard, Suite 208, Sherman Oaks, California 91423,
County of Los Angeles. The Corporation may have such other offices, either
within or without the State of California, as the Board of Directors may
designate or as the business of the Corporation may require from time to time.

                                  ARTICLE II
                                 SHAREHOLDERS

SECTION 1. Annual Meeting:
- -------------------------

The annual meeting of the shareholders shall be held within one month of the
close of the fiscal year of the Corporation, for the purpose of electing
directors, and transacting such other business as may properly come before the
meeting.

SECTION 2. Special Meetings:
- ---------------------------

Special meetings of the Shareholders, for any purpose(s), unless otherwise
prescribed by statute, may be called by the President or Board of Directors, and
shall be called by the President at the request of the holders of not less than
ten per cent (10%) of all the outstanding shares of the Corporation entitled to
vote at the meeting.

SECTION 3. Place of Meeting:
- ---------------------------

The Board of Directors may designate any place, either within or without the
State of California, unless otherwise prescribed by statute, as the place of
meeting for any annual meeting or for any special meeting. A waiver of notice
signed by all shareholders entitled to vote at a meeting may designate any
place, within or without the State of California, unless otherwise prescribed by
statute, as the place for the holding of such meeting. If no designation is
made, the place of meeting shall be the principal office of the Corporation.

SECTION 4. Notice of Meetings:
- -----------------------------

Written notice stating the place, day and hour of the meeting and, in case of a
special meeting, the purpose or purposes for which the meeting is called, shall
unless otherwise prescribed by statute, be delivered not less than ten or nor
more than fifty days before the date of the meeting, to each shareholder of
record entitled to vote at such meeting. If mailed, such notice shall be deemed
to be
<PAGE>

delivered when deposited in the United States Mail, addressed to the shareholder
at his address as it appears on the stock transfer books of the Corporation,
with postage thereon prepaid.

SECTION 5. Closing of Transfer Books or Fixing of Records:
- ---------------------------------------------------------

For the purpose of determining shareholders entitled to notice of or to vote at
any meeting of shareholders or any adjournment thereof, or shareholders entitled
to receive payment of any dividend, or in order to make a determination of
shareholders for any other proper purpose, the Board of Directors of the
Corporation may provide that the stock transfer books shall be closed for a
stated period, but not to exceed in any case fifty (50) days. If the stock
transfer books shall be closed for the purpose of determining shareholders
entitled to notice of or to vote at a meeting of shareholders, such books shall
be closed for at least 5 days immediately preceding such meeting. In lieu of
closing the stock transfer books, the Board of Directors may fix in advance a
date as the record date for any such determination of shareholders, such date in
any case to be not more than 30 days and, in case of a meeting of shareholders,
not less than 10 days prior to the date on which the particular action requiring
such determination of shareholders is to be taken. If the stock transfer books
are not closed and no record date is fixed for the determination of shareholders
entitled to notice of or to vote at a meeting of shareholders, or shareholders
entitled to receive payment of a dividend, the date on which notice of the
meeting is mailed or the date on which the resolution of the Board of Directors
declaring such dividend is adopted, as the case may be, shall be the record date
for such determination of shareholders. When a determination of shareholders
entitled to vote at any meeting of shareholders has been made as provided in
this section, such determination shall apply to any adjournment thereof.

SECTION 6. Voting Lists:
- -----------------------

The officer or agent having charge of the stock transfer books for shares of the
corporation shall make a complete list of the shareholders entitled to vote at
each meeting of shareholders or any adjournment thereof, arranged in
alphabetical order, with the address of and the number of shares held by each.
Such list shall be produced and kept open at the time and place of the meeting
and shall be subject to the inspection of any shareholder during the whole time
of the meeting for the purposes thereof.

SECTION 7. Quorum:
- -----------------

A majority of the outstanding shares of the Corporation entitled to vote,
represented in person or by proxy, shall constitute a quorum at a meeting of
shareholders. If less than a majority of the outstanding shares are represented
at a meeting, a majority of the shares so represented may adjourn the meeting
from time to time without further notice. At such adjourned meeting at which a
quorum shall be present or represented, any business may be transacted which
might have been transacted at the meeting as originally noticed. The
shareholders present at a duly organized meeting may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
shareholders to leave less than a quorum.

SECTION 8. Proxies:
- ------------------
<PAGE>

At all meetings of shareholders, a shareholder may vote in person or by proxy
executed in writing by the shareholder or by his duly authorized attorney-in-
fact. Such proxy shall be filed with the secretary of the Corporation before or
at the time of the meeting. A meeting of the Board of Directors may be had by
means of a telephone conference or similar communications equipment by which all
persons participating in the meeting can hear each other, and participation in a
meeting under such circumstances shall constitute presence at the meeting.

SECTION 9. Voting of Shares:
- ---------------------------

Each outstanding share entitled to vote shall be entitled to one vote upon each
matter submitted to a vote at a meeting of shareholders.

SECTION 10. Voting of Shares by Certain Holders:
- -----------------------------------------------

(a)  Shares standing in the name of another corporation may be voted by such
officer, agent or proxy as the Bylaws of such corporation may prescribe or, in
the absence of such provision, as the Board of Directors of such corporation may
determine.

(b)  Shares held by an administrator, executor, guardian or conservator may be
voted by him, either in person or by proxy, without a transfer of such shares
into his name. Shares standing in the name of a trustee may be voted by him,
either in person or by proxy, but no trustee shall be entitled to vote shares
held by him without a transfer of such shares into his name.

(c)  Shares standing in the name of a receiver may be voted by such receiver,
and shares held by or under the control of a receiver may be voted by such
receiver without the transfer thereof into his name, if authority to do so be
contained in an appropriate order of the court by which such receiver was
appointed.

(d)  A shareholder whose shares are pledged shall be entitled to vote such
shares until the shares have been transferred into the name of the pledgee, and
thereafter the pledgee shall be entitled to vote the shares so transferred.

(e)  Shares of its own stock belonging to the Corporation shall not be voted,
directly or indirectly, at any meeting, and shall not be counted in determining
the total number of outstanding shares at any given time.

SECTION 11. Informal Action by Shareholders:
- -------------------------------------------

Unless otherwise provided by law, any action required to be taken at a meeting
of the shareholders, or any other action which may be taken at a meeting of the
shareholders, may be taken without a meeting if a consent in writing, setting
forth the action so taken, shall be signed by all of the shareholders entitled
to vote with respect to the subject matter thereof.

                                  ARTICLE III
                              BOARD OF DIRECTORS
<PAGE>

SECTION 1. General Powers:
- -------------------------

The business and affairs of the Corporation shall be managed by its Board of
Directors.

SECTION 2. Number, Tenure and Qualifications:
- --------------------------------------------

The number of directors of the Corporation shall be fixed by the Board of
Directors, but in no event shall be less than three (3). Each director shall
hold office until the next annual meeting of shareholders and until his
successor shall have been elected and qualified.

SECTION 3. Regular Meetings:
- ---------------------------

A regular meeting of the Board of Directors shall be held without other notice
than this By-Law immediately after, and at the same place as, the annual meeting
of shareholders. The Board of Directors may provide, by resolution, the time and
place for the holding of additional regular meetings without notice other than
such resolution.

SECTION 4. Special Meetings:
- ---------------------------

Special meetings of the Board of Directors may be called by or at the request of
the President or any two directors. The person or persons authorized to call
special meetings of the Board of Directors may fix the place for holding any
special meeting of the Board of Directors called by them.

SECTION 5. Notice:
- -----------------

Notice of any special meeting shall be given at least one (1) day previous
thereto by written notice delivered personally or mailed to each director at his
business address, or electronically. If mailed, such notice shall be deemed to
be delivered when deposited in the United States Mail so addressed, with postage
thereon prepaid. If notice be given electronically, such notice shall be deemed
to be delivered when the transmission is delivered to the director. Any
directors may waive notice of any meeting. The attendance of a director at a
meeting shall constitute a waiver of notice of such meeting, except where a
director attends a meeting for the express purpose of objecting to the
transaction of any business because the meeting is not lawfully called or
convened.

SECTION 6. Quorum:
- -----------------

A majority of the number of directors fixed by Section 2 of this Article III
shall constitute a quorum for the transaction of business at any meeting of the
Board of Directors, but if less than such majority is present at a meeting, a
majority of the directors present may adjourn the meeting from time to time
without further notice.

SECTION 7. Manner of Action:
- ---------------------------

The act of the majority of the directors present at a meeting at which a quorum
is present shall be the act of the Board of Directors.
<PAGE>

SECTION 8. Action Without a Meeting:
- -----------------------------------

Any action that may be taken by the Board of Directors at a meeting may be taken
without a meeting if a consent in writing, setting forth the action so to be
taken, shall be signed before such action by all of the directors.

SECTION 9. Vacancies:
- --------------------

Any vacancy occurring in the Board of Directors may be filled by the affirmative
vote of a majority of the remaining directors though less than a quorum of the
Board of Directors, unless otherwise provided by law. A director elected to fill
a vacancy shall be elected for the unexpired term of his predecessor in office.
Any directorship to be filled by reason of an increase in the number of
directors may be filled by election by the Board of Directors for a term of
office continuing only until the next election of directors by the shareholders.

SECTION 10. Compensation:
- ------------------------

By resolution of the Board of Directors, each director may be paid his expenses,
if any, of attendance at each meeting of the Board of Directors, and may be paid
a stated salary as director or compensation in the form of stock in the
Corporation or a fixed sum for attendance at each meeting of the Board of
Directors or any combination thereof. No such payment shall preclude any
director from serving the Corporation in any other capacity and receiving
compensation therefor.

SECTION 11. Presumption of Assent:
- ---------------------------------

A director of the Corporation who is present at a meeting of the Board of
Directors at which action on any corporate matter is taken shall be presumed to
have assented to the action taken unless his dissent shall be entered in the
minutes of the meeting or unless he shall file his written dissent to such
action with the person acting as the Secretary of the meeting before the
adjournment thereof, or shall forward such dissent by registered mail to the
Secretary of the Corporation immediately after the adjournment of the meeting.
Such right to dissent shall not apply to a director who voted in favor of such
action.

The officers of the Corporation shall be a President, one or more Vice
Presidents, a Secretary and a Treasurer, each of whom shall be elected by the
Board of Directors. Such other officers and assistant officers as may be deemed
necessary may be elected or appointed by the Board of Directors, including a
Chairman of the Board. In its discretion, the Board of Directors may leave
unfilled for any such period as it may determine any office except those of
President and Secretary. Any two or more offices may be held by the same person,
except for the offices of President and
<PAGE>

Secretary, Chairman and Secretary and Chairman and President, which may not be
held by the same person. Officers may be directors or shareholders of the
Corporation.

SECTION 2. Election and Term of Office:
- --------------------------------------

The officers of the Corporation to be elected by the Board of Directors shall be
elected annually by the Board of Directors at the first meeting of the Board of

officers shall not be held at such meeting, such election shall be held as soon
thereafter as conveniently as it may be. Each officer shall hold office until
his successor shall have been duly elected and shall have qualified, or until
his death, or until he shall resign or shall have been removed in the manner
hereinafter provided.

SECTION 3. Removal:
- ------------------

Any officer or agent may be removed by the Board of Directors whenever, in its
judgment, the best interests of the Corporation will be served thereby, but such
removal shall be without prejudice to the contract rights, if any, of the person
so removed. Election or appointment of an officer or agent shall not of itself
create contract rights, and such appointment shall be terminable at will.

SECTION 4. Vacancies:
- --------------------

A vacancy in any office because of death, resignation, removal, disqualification
or otherwise, may be filled by the Board of Directors for the unexpired portion
of the term.

proper officer of the Corporation thereunto authorized by the Board of
Directors, certificates for shares of the Corporation, any deeds, mortgages,
bonds, contracts, or other instruments which the Board of Directors has
authorized to be executed, except in cases where the signing and execution
thereof shall be expressly delegated by the Board of Directors or by these
Bylaws to some other officer or agent of the Corporation, or shall be required
by law to be otherwise signed or executed; and in general shall perform all
duties incident to the office of President and such other duties as may be
prescribed by the Board of Directors from time to time.

SECTION 6. President and Vice President/s:
- -----------------------------------------

(a)  In the absence of the CEO or in event of his death, inability or refusal to
act, the President shall perform the duties of the CEO, and when so acting,

CEO. The President shall perform such other duties as from time to time may be
assigned to him by the CEO or by the Board of Directors.
<PAGE>

(b)  If there is more than one Vice President, each Vice President shall succeed
to the duties of the President in order of rank as determined by the Board of
Directors. If no such rank has been determined, then each Vice President shall

earliest date having the first rank.

SECTION 7. Secretary:

The Secretary shall: (a) keep the minutes of the proceedings of the shareholders
and of the Board of Directors in one or more minute books provided for that
purpose; (b) see that all notices are duly given in accordance with the

of the Corporation; and (g) in general perform all duties incident to the office
of the Secretary and such other duties as from time to time may be assigned to
his/her by the CEO or by the Board of Directors.

SECTION 8. Treasurer:
- --------------------

The Treasurer shall: (a) have charge and custody of and be responsible for all
funds and securities of the Corporation; (b) receive and give receipts for
moneys due and payable to the Corporation from any source whatsoever, and
deposit all such moneys in the name of the Corporation in such banks, trust
companies or other depositories as shall be selected in accordance with the
provisions of Article VI of these Bylaws; and (c) in general perform all of the
duties incident to the office of Treasurer and such other duties as from time to
time may be assigned to him by the CEO or by the Board of Directors. If required
by the Board of Directors, the Treasurer shall give a bond for the faithful
discharge of his duties in such sum and with such sureties as the Board of
Directors shall determine.

SECTION 9. Salaries:
- -------------------

The salaries of the officers shall be fixed from time to time by the Board of
Directors, and no officer shall be prevented from receiving such salary by
reason of the fact that he is also a director of the Corporation.

                                   ARTICLE V
                                   INDEMNITY

follows:

(a)   Every director, officer, or employee of the Corporation shall be
indemnified by the Corporation against all expenses and liabilities, including
counsel fees, reasonably incurred by or imposed upon him in connection with any

by reason of his being or having been a director, officer, employee or agent of
the Corporation or is or was serving at the request of the Corporation as a
director,
<PAGE>

officer, employee or agent of the corporation, partnership, joint venture, trust
or enterprise, or any settlement thereof, whether or not he is a director,
officer, employee or agent at the time such expenses are incurred, except in
such cases wherein the director, officer, or employee is adjudged guilty of
willful misfeasance or malfeasance in the performance of his duties; provided
that in the event of a settlement the indemnification herein shall apply only
when the Board of Directors approves such settlement and reimbursement as being
for the best interests of the Corporation.

(b)  The Corporation shall provide to any person who is or was a director,
officer, employee, or agent of the Corporation or is or was serving at the
request of the Corporation as a director, officer, employee or agent of the
corporation, partnership, joint venture, trust or enterprise, the indemnity
against expenses of suit, litigation or other proceedings which is specifically
permissible under applicable law.

(c)  The Board of Directors may, in its discretion, direct the purchase of
liability insurance by way of implementing the provisions of this Article V.

<PAGE>

Certificates representing shares of the Corporation shall be in such form as

thereof for all purposes. Provided, however, that upon any action undertaken by
the shareholders to elect S Corporation status pursuant to Section 1362 of the

restriction on transfer shall be made a part of the bylaws so long as said
agreement is in force and effect.

                     Article VI--Duration and Termination


6.1  The rights and licenses granted to DCH under Article II and the obligation
     to pay royalty under Article IV shall continue until January 1, 2015, or
     until the expiration of Sandia Patent Rights, whichever occurs first,
     unless earlier terminated as specified in Article VI. Except for DCH's
     rights and licenses granted under Article II, all other provisions relating
     to DCH and intended to survive the date set forth in Paragraph 6. 1, and
     the expiration of Sandia Patent Rights and any such early termination,
     shall survive. DCH's obligation to pay royalty shall cease in the event all
     claims of the Sandia Patent rights covering the Licensed Product are held
     invalid by a federal court in a final judgment from which no appeal is
     taken.

6.2  Following termination of the rights and licenses granted by Sandia under
     this License Agreement, as specified in Paragraphs 6.3 through 6.6 hereof,
     DCH shall have no further rights and licenses under Article II.

6.3  Termination of DCH's rights and licenses under this License Agreement for
     any reason shall not relieve DCH of any obligation or liability accrued
     either before or after the termination.

6.4  Sandia may terminate the right and license by Article II if DCH, at any
     time:

      (a)  defaults in the payment of any royalty due to Sandia;

      (b)  commits any material breach of this License Agreement; or

      (c)  makes any false statement;

     and fails to remedy or cure any such default, breach or false statement
     within sixty (60) days after written notice of the default, breach or false
     statement is given by Sandia.


6.5  Sandia may terminate the rights and licenses granted by Article II, if the
     combined royalties for any two (2) consecutive semiannual accounting
     periods hereunder are less than the minimum annual royalty, by giving DCH a
     written notice of its election to do so, specifying an effective date of
     termination not less than sixty (60) days from the date of such notice. DCH
     may prevent such termination by paying before the effective date of
     termination specified in such notice, the difference between royalties
     accrued and paid by DCH for the two (2) consecutive annual accounting
     periods and the minimum annual royalty.

6.6  Sandia may terminate the rights and licenses granted by Article II by
     giving written notice to DCH in the event DCH experiences any of the
     following events: dissolution, insolvency, filing of a voluntary petition
     in bankruptcy (other than reorganization under Chapter 11), adjudication as
     a bankrupt pursuant to an involuntary petition, appointment by a court of a
     temporary or permanent receiver, trustee or custodian for its business, or
     an assignment for

     the benefit of creditors. Such termination shall be effective immediately
     upon the giving of such notice.

7.1  Sandia warrants that it has the right to grant the rights and licenses in
     Article II.

7.2  Sandia makes no warranty, express or implied, as to the accuracy or utility

     implied, that the use of any Sandia Patent Rights made available to DCH
     under this License Agreement will not infringe any United States or foreign
     patent, copyright or trade secret. Under this License Agreement, Sandia
     Patent Rights are made available to DCH on an "AS-IS" basis.

     EXCEPT FOR THE WARRANTIES EXPRESSLY PROVIDED HEREIN, ALL WARRANTIES,
     EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF
     MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, ARE EXCLUDED

     shall be liable for any loss, damage (including incidental, consequential
     and special), injury or other casualty of whatsoever kind, or by whomsoever
     caused, to the person or property of anyone, including DCH, arising out of
     or resulting from the licenses granted to DCH herein, or the accuracy and
     validity of Sandia Patent Rights, or from any system or component thereof
     made, used, sold, leased or transferred by DCH. DCH agrees for itself, its
     successors and assigns, to defend Sandia and to indemnify and hold Sandia
     and the Government, harmless from and against all claims, demands,
     liabilities, suits or actions (including all reasonable expenses and

5.1  DCH shall not, without the express written consent of Sandia, make any
     verbal or written statements or perform any act indicating that Sandia

     Specifically, DCH shall not, without the express written consent of Sandia,
     associate or in any way connect any name or trademark of Sandia with any

LIMITED EXCLUSIVE FIELD OF USE PATENT LICENSE AGREEMENT
DCH TECHNOLOGY, INC.

THIS LICENSE AGREEMENT is entered into by and between THE REGENTS OF THE
UNIVERSITY OF CALIFORNIA, a nonprofit educational institution and a public
corporation of the State of California, hereinafter referred to as the
"University;" and DCH Technology, Inc., 27811 Ave. Hopkins, Suite 6, Valencia,
CA 91355, a Colorado Corporation, hereinafter referred to as the "Licensee," the
parties to this License Agreement being referred to individually as a "Party,"
and collectively as "Parties."
<PAGE>

BACKGROUND

The University conducts research and development at the Los Alamos National
Laboratory (LANL) for the U.S. Government under Contract No. W-7405-ENG-36 with
the U.S. Department of Energy (DOE).

Rights in inventions and technical data made in the course of the University's
research and development at LANL are governed by the terms and conditions of the
Contract.

Certain TECHNOLOGY relating to an Annular Feed Air Breathing Fuel Cell Stack has
been developed in the course of the University's research and development at
LANL and is covered by the University's PATENT RIGHTS as defined hereinbelow.

The University desires that such TECHNOLOGY be developed and utilized to the
fullest extent possible so as to enhance the accrual of economic and
technological benefits to the U@S. domestic economy and to provide the benefit
of federally sponsored research to U.S. industrial competitiveness.

The University is therefore willing to grant to Licensee, and the Licensee
desires to obtain from the University certain exclusive rights for the
commercial development, manufacture, use, and sale of the TECHNOLOGY.

NOW, THEREFORE, the Parties agree as follows-

1. DEFINITIONS

1.1   "TECHNOLOGY" means technical information, know-how, data and PATENT RIGHTS
owned or controlled by the University and relating to Annular Feed Air Breathing
Fuel Cell Stacks.

1.2   "PATENT RIGHTS" means the University's rights arising from U.S. patents or
applications, including any continuing applications, divisionals, and reissues
thereof (but not including continuations-in-part); and any patents issuing on
said applications where elected by Licensee and identified in Appendix A,
attached hereto.

1.3   "LICENSED METHOD" means any method, procedure or process whose use would
constitute, but for the license granted to Licensee herein, an infringement of
any subsisting claim of any patent or patent application identified in Appendix
A.

1.4   "LICENSED PRODUCT" means any article of manufacture, machine or
composition of matter whose manufacture, use, sale, or offer for sale would
constitute, but for the license granted to Licensee herein, an infringement of
any subsisting claim of any patent or patent application identified in Appendix
A, and any article of manufacture, machine or composition of matter produced
through the practice of LICENSED METHOD or whose only substantial use is to
practice LICENSED METHOD.

1.5   "LICENSED INVENTION" means any LICENSED PRODUCT or LICENSED METHOD.

1.6   "SALES" means disposing of LICENSED PRODUCTS by sale, lease, or other
delivery or practicing LICENSED METHOD. A Sale occurs when LICENSED PRODUCTS are
invoiced, or when delivered to a third person, whichever occurs first.
<PAGE>

1.7.  "SALES PRICE" means the invoice prices for SALES or, if LICENSED
INVENTIONS are not sold but otherwise disposed of, the selling price at which
products of similar kind and quality, sold in similar quantities in which
LICENSED INVENTIONS are being disposed of, are being offered for sale by
Licensee. Where such LICENSED PRODUCTS are not currently being offered for Sale
by Licensee, the SALES PRICE for purposes of computing royalties is the average
selling price at which similar kind and quality, sold in similar quantities, are
then currently being offered for sale by other companies. If such products are
not currently sold or offered for sale by others, then the SALES PRICE, for
purposes of computing royalties, is Licensee's cost of manufacture determined by
Licensee's customary accounting procedures, plus Licensee's standard mark-up.

1.8   "NET SALES" means the gross amounts for SALES at SALES PRICE by Licensee
and its' sublicensee(s), less the following deductions where applicable: (a)
SALES returns; (b) normal and customary allowances, (c) trade discounts; (d)
SALES to the U.S. Government pursuant to Paragraph 4.2 and (e) transportation
charges, duties and tariffs only if separately stated on an invoice; but before
deduction of sales and excise taxes, costs of insurance, and agents'
commissions.

1.9   "AFFILIATE" means:
a) any business entity that owns fifty (50%) percent or more of Licensee's
outstanding stock; or
b) any business entity of which Licensee owns fifty (50%) or more of such
entity's outstanding stock.

1.10  "FIELD OF USE" means a limitation of the application or utilization of
PATENT RIGHTS and is defined in Appendix A.

2. GRANT

2.1   The University grants to the Licensee, subject to Paragraphs 2.2 and 2.3,
an exclusive license to make, have made, use, import, sell and offer to sell
LICENSED INVENTION under the PATENT RIGHTS, with the right to sublicense
others under the terms of Article 3, limited to the FIELD OF USE recited in
Appendix A.

2.2   Rights not expressly granted to Licensee herein are expressly reserved to
the University.

2.3   The University expressly reserves the right to use the TECHNOLOGY,
including the right to make, have made, use and have used LICENSED INVENTION for
any purpose, including Cooperative Research and Development Agreements (CRADAs),
Work for Others (WFOs), and User Facility Agreements (UFAs).

2.4   The U.S. Government has a nonexclusive, nontransferable, irrevocable,
paid-up license to practice or have practiced throughout the world, for or on
behalf of the United States Government, inventions covered by the University's
PATENT RIGHTS, and has certain other rights under 35 U.S.C. 200-212 and
applicable implementing regulations and under the U.S. Department of Energy
Confirmatory License, attached as Appendix B to this License Agreement.

2.5   Under 35 U.S.C. 203, the U.S. Department of Energy has the right to
require the Licensee to grant a nonexclusive, partially exclusive or exclusive
license under the PATENT RIGHTS in any field of use to a responsible applicant
or applicants, 48 CFR 27.304-1(g).
<PAGE>

2.6   The Licensee will make available to the University and will grant an
irrevocable, paid-up, royalty-free nonexclusive license to the University to
make and use for purposes of performing work for and on behalf of the U.S.
government any improvements or developments to the TECHNOLOGY made by Licensee.

3. SUBLICENSES

3.1   The University grants to Licensee the right to grant sublicenses to third
parties to make, have made, use and sell LICENSED INVENTIONS in which the
Licensee has current limited exclusive rights under this License Agreement.

(a) Sublicenses granted under this clause must contain all of the conditions,
restrictions and reservations of this License Agreement, except for those
provisions related too the fees and royalties, and shall preserve the rights and
reservations of the University and the U.S. Government existing under this
License Agreement.

3.2   Licensee shall provide the University with a copy of each sublicense by at
least thirty (30) days prior to its execution.

3.3.  Licensee must pay to the University the payments prescribed in Appendix C,
and deliver all reports due the Licensor from sublicensees. With respect to any
sublicense, this obligation continues as long as a sublicense granted by
Licensee is in effect, and is an obligation of the Licensee whether or not
royalty payments are actually received by Licensee from its sublicensee(s).

3.4   Termination of this License Agreement automatically operates as an
assignment by Licensee to the University of all Licensee's right, title and
interest in and to each sublicense granted by Licensee. If this License
Agreement is terminated by either Party, any sublicensee(s) not in default of
the terms and conditions of its sublicense agreement with Licensee, may make a
written election to continue such sublicense agreement as a license agreement
with the University. Licensee will give its' sublicensee(s) written notice
thirty (30) days prior to the effective date of termination of this License
Agreement. Sublicensee(s) must submit a written election to the University
within thirty (30) days thereafter.

4. FEES AND ROYALTIES

4.1   For the rights, privileges and license granted under this License
Agreement, Licensee shall pay to the University the fees and royalties specified
in Appendix C.

4.2   Notwithstanding Paragraph 4.1 above, Licensee has no obligation to pay
royalties on any SALE of any LICENSED INVENTION to the U.S. Government or any
agency thereof or any U.S. Government contractor who certifies that its purchase
of the LICENSED INVENTION is for or on behalf of the U.S. Government. Licensee
will not impose royalty charges on SALES of LICENSED INVENTION to U.S.
Government entities, and will refund to them any royalty collected on such
SALES.

4.3   The first royalty payment due under this License Agreement is based on
NET SALES by Licensee from the effective date of this License Agreement through
June 30" of the same calendar year, if the effective date is before June 30th,
or, through December 31st, if the effective date is after June 30th. Payment
<PAGE>

must be made within one month from the end of such period. Subsequent royalty
payments shall be calculated based on NET SALES by Licensee during the
semiannual periods extending from January lst through June 30th   and from July
1st through December 31st of each year, for as long as this License Agreement
remains in effect. Royalty payments must be paid within one month from the end
of the respective semiannual period (i.e. July 30th and January 31st).

4.4   All payments due the University must be paid in United States currency to
the University of California, Los Alamos National Laboratory, at the address set
forth in Paragraph 19.1. Licensee must convert NET SALES invoiced in foreign
currencies into equivalent United States currency at the exchange rate for the
foreign currency prevailing as of the last day of the reporting period, as
reported in the Wall Street Journal.

5. DILIGENCE

5.1   Licensee shall use its best efforts to bring one or more LICENSED
INVENTION to market through a thorough, vigorous and diligent program for
exploitation of the PATENT RIGHTS and to continue active, diligent marketing
efforts for one or more LICENSED INVENTION throughout the life of this License
Agreement.

5.2   To be in compliance with Paragraph 5.1, Licensee must adhere to the
Milestones set out in Appendix D.

5.3   Article 5 is a material term of this Agreement, without which the license
grant under Article 2 would not have been made, and Licensee's failure to
perform in accordance with Paragraphs 5.1 and 5.2 above shall be grounds for the
University to terminate this License Agreement pursuant to Paragraph 9.1 of this
License Agreement.

6. REPORTS

6.1   Progress Reports. Licensee must submit semiannual Progress Reports
certified by an officer of the Licensee. Such reports are due on the date that
royalty payments are due (July 30th and January 31st), AND MUST BE SUBMITTED
REGARDLESS OF WHETHER ANY PAYMENT IS MADE. This report covers the Licensee's
activities related to the development of the TECHNOLOGY and the securing of
approvals necessary for commercialization of the TECHNOLOGY. The Progress
Reports must conform with the Progress Report Format set forth in Appendix E
hereof. Progress Reports marked by Licensee as proprietary financial or business
information of Licensee will be treated by the University as proprietary
information.

6.2   Financial Reports. Licensee must submit semiannual Financial Reports. Such
reports are due on the date that royalty payments are due (July 30th and January
31st), AND MUST BE SUBMITTED REGARDLESS OF WHETHER ANY PAYMENT IS ACTUALLY MADE.
Financial Reports must be certified by an officer of the Licensee, must conform
with the Financial Report Format set forth in Appendix F hereof, must cover the
period for which royalty payments are calculated, and must show total SALES or
commercial uses made of LICENSED INVENTION by Licensee and any sublicensee(s)
during the reporting period. IF NO SALE, SUBLICENSE, OR USE OF LICENSED PRODUCT
OR LICENSED METHOD HAS BEEN MADE DURING A REPORTING PERIOD, A STATEMENT TO THIS
EFFECT MUST BE MADE. Financial Reports marked by Licensee as proprietary
financial or business information of the Licensee will be treated as such by the
University. Licensee's failure to submit Financial Reports pursuant to this
<PAGE>

Paragraph shall be grounds for the University to terminate this License
Agreement pursuant to Paragraph 9.1.

7. BOOKS AND RECORDS

7.1   The Licensee must keep books and records according to Generally Accepted
Accounting Principles, accurately showing all SALES of LICENSED PRODUCTS or
practice of the LICENSED METHOD by Licensee or sublicensees under the terms of
this License Agreement. Such books and records must be open to inspection and
audit on a proprietary basis by representatives or agents of the University at
reasonable times, but in no event more than once for each calendar year, for the
purpose of verifying the accuracy of the semiannual Financial and Progress
Reports and the royalties due. Licensee may request that any such inspection and
audit be conducted by an independent auditor, in which event, Licensee will pay
the reasonable costs of such auditor.

7.2   The fees and expenses of the University's representatives performing the
inspection and audit will be borne by the University. However, if an error in
royalties owed the University of more than ten thousand U.S. Dollars
($10,000.00) is discovered by the representatives of the University, then
Licensee will pay the fees and expenses of said representatives within thirty
(30) days after receipt of invoice.

7.3   The books and records required by Article 7 must be preserved for at
least three (3) years from the date that the royalty payments were due.

8. TERM OF THE LICENSE AGREEMENT

8.1   This License Agreement is effective as of the later of the dates of
execution by the Parties and the University's receipt of the License Issue Fee
(as specified in Appendix C).

8.2   This License Agreement is in full force and effect from the effective
date and remains in effect until the expiration of the last to expire of the
patents included within the University's PATENT RIGHTS, unless sooner terminated
by operation of law or by acts of either of the Parties in accordance with the
terms of this License Agreement.

8.3   Licensee shall provide notice to University of its intention to file a
voluntary petition in bankruptcy or of another party's intention to file an
involuntary petition in bankruptcy for Licensee, said notice to be received by
University at least thirty (30) days prior to filing such petition. The
University may terminate this License Agreement upon receipt of such notice at
its sole discretion. Licensee's failure to provide such notice to University
will be deemed a material, pre-petition, incurable breach of this License
Agreement and the Agreement will terminate automatically on the date of filing
such voluntary or involuntary petition in bankruptcy.

9. TERMINATION BY THE UNIVERSITY

9.1   If the Licensee fails to deliver to the University any report when due, or
fails to pay any royalty or fee when due, or if the Licensee breaches any
material term of this License Agreement, including, but not limited to, Article
5. DILIGENCE, the University may give written notice of default to the Licensee.
If the Licensee fails to cure the default within thirty (30) days from the date
of delivery of notice to Licensee, the University has the right to terminate
this License Agreement. This License Agreement will terminate upon delivery of
<PAGE>

written notice of termination to the Licensee. Termination does not relieve the
Licensee of its obligation to pay any royalty or license fees due or owing at
the time of termination and does not impair any accrued right of the University.
Licensee will return all tangible property given to Licensee by the University
in support of the rights granted hereunder and return or destroy all intangible
property as directed by the University.

10. TERMINATION BY THE LICENSEE

10.1  The Licensee may terminate this License Agreement by giving written notice
to the University. Such termination will be effective ninety (90) days from the
date of delivery of the notice, and all the Licensee's rights under this License
Agreement will cease as of that date.

10.2  If Licensee exercises its option to terminate this License Agreement
without cause, then Licensee agrees to pay the University, the Annual License
Fee multiplied by the number of years remaining under this License Agreement
(from the date of notification of termination to the expiration of the last to
expire of the patents included within the University's PATENT RIGHTS) multiplied
by 0.70, in a lump sum as liquidated damages, on the effective date of
termination.

10.3  Termination pursuant to this Article does not relieve the Licensee of any
obligation or liability accrued by Licensee prior to the effective date of
termination or affect any rights of the University arising under this Agreement
prior to termination. Licensee will return all tangible property given to
Licensee by the University in support of the rights granted hereunder and return
or destroy all intangible property as directed by the University.

11. PATENT PROSECUTION AND MAINTENANCE

11.1  The University will diligently prosecute any U.S. patent applications
identified in Appendix A, and will maintain any U.S. patents identified in
Appendix A, using counsel of its choice. The University will provide the
Licensee, on request, with copies of relevant documentation relating to any such
patent prosecution. The Licensee will hold such documentation in confidence.

11.2  The University will use its best efforts to amend any patent application
to include claims reasonably requested by the Licensee and required to protect
the LICENSED INVENTION.

11.3  The Licensee acknowledges that Patent Rights in foreign countries are not
available under the University's PATENT RIGHTS.

12. USE OF NAMES, TRADENAMES, AND TRADEMARKS

12.1  Nothing contained in this License confers any right to use in advertising,
publicity, or other promotional activities any name, tradename, trademark, or
other designation of either Party hereto (including any contraction,
abbreviation, or simulation of any of the foregoing). Unless required by law,
the use of the name "the University of California" or the name of any facility
or campus of the University of California is expressly prohibited.

12.2  The University may disclose to third parties the existence of this License
Agreement and the extent of the grant in Article 2, but must not disclose
information identified as proprietary by Licensee under 12.4, except where the
<PAGE>

University is required to release the information under either the California
Public Records Act or other applicable law. A decision to release information
under applicable law will be at the sole discretion of the University.

12.3  Licensee may disclose to third parties the existence of this License
Agreement and the terms and conditions to the extent determined appropriate by
Licensee.

12.4  Licensee will mark those portions of a copy of this License Agreement
which Licensee believes contain proprietary business information of Licensee and
return such copy to the University within thirty (30) days of the effective date
of this License Agreement.

13. WARRANTY BY THE UNIVERSITY

13.1  The University warrants that it has the lawful right to grant this
license, subject to DOE assignment of rights in the TECHNOLOGY to the University
in the event such rights are not owned by the University, and that it has not
granted any rights under the University's PATENT RIGHTS to any other party that
diminish any right granted to Licensee, except as required by action of law or
by the University's prime contract with DOE.

13.2  This license is provided WITHOUT warranty of merchantability or fitness
for a particular purpose or any other warranty, express or implied. The
University makes no representation or warranty that the LICENSED PRODUCTS or
LICENSED METHODS will not infringe any patent or other proprietary right.

13.3  IN NO EVENT WILL THE UNIVERSITY BE LIABLEFORANY INCIDENTAL, SPECIAL, OR
CONSEQUENTIAL DAMAGES RESULTING FROM EXERCISE OF THIS LICENSE OR THE USE OF
LICENSED PRODUCTS OR LICENSED METHODS.

13.4  Nothing in this License Agreement shall be construed as:

a.      a warranty or representation by the University as to the validity or
scope of University's PATENT RIGHTS;

b.      an obligation to bring or prosecute actions or suits against third
parties for patent infringement, except as provided in Article 14
(infringement);

c.      conferring by implication, estoppel, or otherwise any license or rights
under any patents of the University other than University's PATENT RIGHTS,
copyrights, or other intellectual property of the University; or

d.      an obligation by University to furnish any know-how, technical
assistance, or technical data that is unrelated or unnecessary to the transfer
of the TECHNOLOGY to the Licensee for the purpose of implementing this License
Agreement.

14. INFRINGEMENT

14.1  In the event that either Party to this License Agreement learns of the
infringement of any of University's PATENT RIGHTS, that Party will inform the
other Party in writing and will provide the other Party with available evidence
of the infringement.

14.2  Both Parties will use their best efforts in cooperating with each other to
terminate the infringement without litigation.
<PAGE>

14.3  If the efforts of the Parties are not successful in abating the
infringement within ninety (90) days after the infringer has been formally
notified of infringement by the University, the University has the right to:
a. commence suit on its own account; or
b. commence suit jointly with the Licensee; or
c. refuse to participate in a suit.

The University shall give written notice to the Licensee, of its election,
within ten (10) working days after the expiration of the ninety (90) day period.
If the University elects not to commence suit on its own account or not to
commence suit jointly with the Licensee, then Licensee shall have the right to
commence suit on its own account, and, if required by law, University will join
the suit as nominal party plaintiff if the infringement occurred during the term

from the action, including attorney fees and costs of both Parties and the
defense of any counter-claim brought by the infringer. If legal action is
brought by Licensee, the University will be entitled to [*] percent of any
damage recovery based on lost profits of Licensee or a reasonable royalty or
both. Legal action brought jointly by the University and the Licensee and fully
participated in by both will be at the joint expense of the Parties and all
recoveries will be shared jointly by them in proportion to the share of expenses
paid by each.

14.5  Each Party will cooperate with the other in proceedings instituted
hereunder, provided expenses are borne by the Party bringing suit. Litigation
will be controlled by the Party bringing suit, except that the University will
control the litigation if brought jointly. The University may be represented by
its choice of counsel in any suit brought by the Licensee.

14.6  Neither Party will settle or compromise any suit without the other Party's
written consent.

consent of the University, provided however, that such AFFILIATE is not.-

a) an entity-

(1)     located in, doing business with, or being organized under the laws of a
country, which is considered a sensitive country by DOE based on DOE internal
policies and procedures at the time Licensee requests such assignment, or;

(ii)    substantially controlled by an entity located in, doing business with,
or being organized under the laws of a country, which is considered a sensitive
country by DOE based on DOE internal policies and procedures at the time
Licensee requests such assignment.

[*] Omitted pursuant to request for confidentiality filed with the Securities
    and Exchange Commission.
<PAGE>

This License Agreement is assignable by the Licensee to a non-AFFILIATE only
with the written consent of the University, which consent shall not be

contractor for the Los Alamos National Laboratory, the University may assign
this License Agreement to DOE or to the succeeding management and operating
contractor for LANL, as directed by DOE.

16.3  In the event that a foreign company or government acquires a controlling
interest in Licensee, the University, at its sole option and discretion, may
terminate this License Agreement in accordance with DOE policies. Licensee
agrees to notify the University of any change in its ownership that results in a
foreign company or government acquiring a controlling interest in Licensee,
within thirty (30) days prior to any such occurrence.

17. INDEMNIFICATION - PRODUCT LIABILITY

17.1  The Licensee will indemnify the U.S. Government and the University, and
their officers, employees, and agents, against any damages, costs and expenses,
including attorneys' fees, arising from the commercialization and utilization of
LICENSED PRODUCTS by Licensee and its' sublicensee(s), including but not limited
to the making, using, selling or exporting of products, processes, or services
derived therefrom. This indemnification will include, but will not be limited
to, product liability. To the maximum extent permitted by applicable state and
federal law, Licensee has the option to control the defense of any suit that may
result in Licensee's liability under this section.

17.2 Licensee will insure its activities relating to the License Agreement at
its own expense with an insurance company acceptable to the University or
provide a Certification of Self-Insurance acceptable to the University. Licensee
will obtain, keep in force, and maintain a minimum of [*] of Comprehensive or
Commercial Form General Liability Insurance (including contractual liability and
product liability) or an amount no less than [*], whichever amount is greater.
These coverages will not limit the liability of Licensee in any way. Licensee
will provide the University with certificates of insurance, if requested by the
University, including renewals, that show compliance with these requirements at
least thirty (30) days before the first commercial sale or distribution of
LICENSED PRODUCTS. Licensee's failure to maintain this insurance will be

for a retroactive date of placement prior to or coinciding with the effective
date of this License Agreement.

b. Licensee shall maintain the general liability insurance specified herein
during (a) the period that the LICENSED PRODUCT is being commercially
distributed or sold (other than for the purpose of obtaining regulatory
approvals) by Licensee or by a sublicensee, AFFILIATE, or agent of Licensee, and
(b) a reasonable period thereafter, but in no event less than five (5) years
from the effective date of this License Agreement.

17.3  Insurance coverage as required under Paragraph 17.2 above shall:

LIMITED NONEXCLUSIVE FIELD OF USE PATENT LICENSE AGREEMENT
DCH TECHNOLOGY, INC.

THIS LICENSE AGREEMENT is entered into by and between THE REGENTS OF THE
UNIVERSITY OF CALIFORNIA, a nonprofit educational institution and a public
corporation of the State of California, hereinafter referred to as the
"University;" and
<PAGE>

DCH Technology, Inc., 27811 Ave. Hopkins, Suite 6, Valencia, CA 91355, a
Colorado Corporation, hereinafter referred to as the "Licensee," the parties to
this License Agreement being referred to individually as a "Party," and
collectively as "Parties."

BACKGROUND

The University conducts research and development at the Los Alamos National
Laboratory (LANL) for the U.S. Government under Contract No. W-7405-ENG-36 with
the U.S. Department of Energy (DOE).

Rights in inventions and technical data made in the course of the University's
research and development at LANL are governed by the terms and conditions of the
Contract.

Certain TECHNOLOGY relating to an Annular Feed Air Breathing Fuel Cell Stack has
been developed in the course of the University's research and development at
LANL and is covered by the University's PATENT RIGHTS as defined hereinbelow.

The University desires that such TECHNOLOGY be developed and utilized to the
fullest extent possible so as to enhance the accrual of economic and
technological benefits to the U.S. domestic economy and to provide the benefit
of federally sponsored research to U.S. industrial competitiveness.

The University is therefore willing to grant to Licensee, and the Licensee
desires to obtain from the University certain exclusive rights for the
commercial development, manufacture, use, and sale of the TECHNOLOGY.

NOW, THEREFORE, the Parties agree as follows-:

1.  DEFINITIONS

1.1    "TECHNOLOGY" means technical information, know-how, data and PATENT
RIGHTS owned or controlled by the University and relating to Annular Feed Air
Breathing Fuel Cell Stacks.

1.2    "PATENT RIGHTS" means the University's rights arising from U.S. patents
or applications, including any continuing applications, divisionals, and
reissues thereof (but not including continuations-in-part); and any patents
issuing on said applications where elected by Licensee and identified in
Appendix A, attached hereto.

1.3    "LICENSED METHOD" means any method, procedure or process whose use would
constitute, but for the license granted to Licensee herein, an infringement of
any subsisting claim of any patent or patent application identified in Appendix
A.

1.4    "LICENSED PRODUCT" means any article of manufacture, machine or
composition of matter whose manufacture, use, sale, or offer for sale would
constitute, but for the license granted to Licensee herein, an infringement of
any subsisting claim of any patent or patent application identified in Appendix
A, and any article of manufacture, machine or composition of matter produced
through the practice of LICENSED METHOD or whose only substantial use is to
practice LICENSED METHOD.

1.5    "LICENSED INVENTION" means any LICENSED PRODUCT or LICENSED METHOD.
<PAGE>

1.6    "SALES" means disposing of LICENSED PRODUCTS by sale, lease, or other
delivery or practicing LICENSED METHOD. A Sale occurs when LICENSED PRODUCTS are
invoiced, or when delivered to a third person, whichever occurs first.

1.7.   "SALES PRICE" means the invoice prices for SALES or, if LICENSED
INVENTIONS are not sold but otherwise disposed of, the selling price at which
products of similar kind and quality, sold in similar quantities in which
LICENSED INVENTIONS are being disposed of, are being offered for sale by
Licensee. Where such LICENSED PRODUCTS are not currently being offered for Sale
by Licensee, the SALES PRICE for purposes of computing royalties is the average
selling price at which similar kind and quality, sold in similar quantities, are
then currently being offered for sale by other companies. If such products are
not currently sold or offered for sale by others, then the SALES PRICE, for
purposes of computing royalties, is Licensee's cost of manufacture determined by
Licensee's customary accounting procedures, plus Licensee's standard mark-up.

1.8    "NET SALES" means the gross amounts for SALES at SALES PRICE by Licensee,
less the following deductions where applicable: (a) SALES returns; (b) normal
and customary allowances; (c) trade discounts; (d) SALES to the U.S. Government
pursuant to Paragraph 3.2 and (e) transportation charges, duties and tariffs
only if separately stated on an invoice; but before deduction of sales and
excise taxes, costs of insurance, and agents' commissions.

1.9    "AFFILIATE" means:

a) any business entity that owns fifty (50%) percent or more of Licensee's
outstanding stock; or
b) any business entity of which Licensee owns fifty (50%) or more of such
entity's outstanding stock.

1.10   "FIELD OF USE" means a limitation of the application or utilization of
PATENT RIGHTS and is defined in Appendix A.

2.  GRANT

2.1    The University grants to the Licensee, subject to Paragraphs 2.2 and 2.3,
a nonexclusive license to make, have made, use, import, sell and offer to sell
LICENSED INVENTION under the PATENT RIGHTS, limited to the FIELD OF USE recited
in Appendix A.

2.2    Rights not expressly granted to Licensee herein are expressly reserved to
the University.

2.3    The Licensee will make available to the University and will grant an
irrevocable, paid-up, royalty-free nonexclusive license to the University to
make and use for any purpose permitted under the Contract any improvements or
developments to the TECHNOLOGY made by Licensee.

2.4    The Licensee will make available to the University and will grant an
irrevocable, paid-up, royalty-free nonexclusive license to the University to
make and use for purposes of performing work for and on behalf of the U.S.
government any improvements or developments to the TECHNOLOGY made by Licensee.

3.1    For the rights, privileges and license granted under this License
Agreement, Licensee shall pay to the University the fees and royalties specified
in Appendix C.

3.2    Notwithstanding Paragraph 4.1 above, Licensee has no obligation to pay
royalties on any SALE of any LICENSED INVENTION to the U.S. Government or any
agency thereof or any U.S. Government contractor who certifies that its purchase
of the LICENSED INVENTION is for or on behalf of the U.S. Government. Licensee
will not impose royalty charges on SALES of LICENSED INVENTION to U.S.
Government entities, and will refund to them any royalty collected on such
SALES.

3.3    The first royalty payment due under this License Agreement is based on
NET SALES by Licensee from the effective date of this License Agreement through
June 30th of the same calendar year, if the effective date is before June 30th
or, through December 31st, if the effective date is after June 30th. Payment
must be made within one month from the end of such period. Subsequent royalty
payments shall be calculated based on NET SALES by Licensee during the
semiannual periods extending from January 1st through June 30th and from July
1st through December 31st of each year, for as long as this License Agreement
remains in effect. Royalty payments must be paid within one month from the end
of the respective semiannual period (i.e. July 30th and January 31st).

3.4    All payments due the University must be paid in United States currency to
the University of California, Los Alamos National Laboratory, at the address set
forth in Paragraph 19.1. Licensee must convert NET SALES invoiced in foreign
currencies into equivalent United States currency at the exchange rate for the
foreign currency prevailing as of the last day of the reporting period, as
reported in the Wall Street Journal.

4.  DILIGENCE

4.1    Licensee shall use its best efforts to bring one or more LICENSED
INVENTION to market through a thorough, vigorous and diligent program for
exploitation of the PATENT RIGHTS and to continue active, diligent marketing

Agreement.

4.2    To be in compliance with Paragraph 4.1, Licensee must adhere to the
Milestones set out in Appendix D.

4.3    Article 4 is a material term of this Agreement, without which the license
grant under Article 2 would not have been made, and Licensee's failure to per-
form in accordance with Paragraphs 4.1 and 4.2 above shall be grounds for the
University to terminate this License Agreement pursuant to Paragraph 8.1 of this
License Agreement.

5.  REPORTS

5.1    Progress Reports. Licensee must submit semiannual Progress

Reports certified by an officer of the Licensee. Such reports are due on the
date that royalty payments are due (July 30th and January 31st), AND MUST BE

Licensee's activities related to the development of the TECHNOLOGY and the
securing of approvals necessary for commercialization of the TECHNOLOGY. The
Progress Reports must conform with the Progress Report Format set forth in
<PAGE>

Appendix E hereof. Progress Reports marked by Licensee as proprietary financial
or business information of Licensee will be treated by the University as
proprietary information.

5.2    Financial Reports. Licensee must submit semiannual Financial Reports.
Such reports are due on the date that royalty payments are due (July 30th and
January 31st), AND MUST BE SUBMITTED REGARDLESS OF WHETHER ANY PAYMENT IS

Licensee, must conform with the Financial Report Format set forth in Appendix F
hereof, must cover the period for which royalty payments are calculated, and
must show total SALES or commercial uses made of LICENSED INVENTION by Licensee
and any sublicensee(s) during the reporting period. IF NO SALE, SUBLICENSE, OR
USE OF LICENSED PRODUCT OR LICENSED METHOD HAS BEEN MADE DURING A REPORTING
PERIOD, A STATEMENT TO THIS EFFECT MUST BE MADE. Financial Reports marked by
Licensee as proprietary financial or business information of the Licensee will
be treated as such by the University. Licensee's failure to submit Financial
Reports pursuant to this Paragraph shall be grounds for the University to
terminate this License Agreement pursuant to Paragraph 8.1.

6.  BOOKS AND RECORDS

6.1    The Licensee must keep books and records according to Generally Accepted
Accounting Principles, accurately showing all SALES of LICENSED PRODUCTS or
practice of the LICENSED METHOD by Licensee under the terms of this License
Agreement. Such books and records must be open to inspection and audit on a
proprietary basis by representatives or agents of the University at reasonable
times, but in no event more than once for each calendar year, for the purpose of
verifying the accuracy of the semiannual Financial and Progress Reports and the
royalties due. Licensee may request that any such inspection and audit be
conducted by an independent auditor, in which event, Licensee will pay the
reasonable costs of such auditor.

6.2    The fees and expenses of the University's representatives performing the
inspection and audit will be borne by the University. However, if an error in
royalties owed the University of more than [*] is discovered by the
representatives of the University, then Licensee will pay the fees and expenses
of said representatives within thirty (30) days after receipt of invoice.

6.3    The books and records required by Article 6 must be preserved for at
least three (3) years from the date that the royalty payments were due.

7.  TERM OF THE LICENSE AGREEMENT

7.1    This License Agreement is effective as of the later of the dates of
execution by the Parties and the University's receipt of the License Issue Fee
(as specified in Appendix C).

7.2    This License Agreement is in full force and effect from the effective
date and remains in effect until the expiration of the last to expire of the
patents included within the University's PATENT RIGHTS, unless sooner terminated
by operation of law or by acts of either of the Parties in accordance with the
terms of this License Agreement.

7.3    Licensee shall provide notice to University of its intention to file a
voluntary petition in bankruptcy or of another party's intention to file an
involuntary petition in bankruptcy for Licensee, said notice to be received by

[*] Omitted pursuant to request for confidentiality filed with the Securities
    and Exchange Commission.
<PAGE>

University at least thirty (30) days prior to filing such petition. The
University may terminate this License Agreement upon receipt of such notice at
its sole discretion. Licensee's failure to provide such notice to University
will be deemed a material, pre-petition, incurable breach of this License
Agreement and the Agreement will terminate automatically on the date of filing
such voluntary or involuntary petition in bankruptcy.

8.  TERMINATION BY THE UNIVERSITY

8.1    If the Licensee fails to deliver to the University any report when due,
or fails to pay any royalty or fee when due, or if the Licensee breaches any
material term of this License Agreement, including, but not limited to, Article
4. DILIGENCE, the University may give written notice of default to the Licensee.
If the Licensee fails to cure the default within thirty (30) days from the date
of delivery of notice to Licensee, the University has the right to terminate
this License Agreement. This License Agreement will terminate upon delivery of
written notice of termination to the Licensee. Termination does not relieve the
Licensee of its obligation to pay any royalty or license fees due or owing at
the time of termination and does not impair any accrued right of the University.
Licensee will return all tangible property given to Licensee by the University
in support of the rights granted hereunder and return or destroy all intangible

B.   It is understood that the University has the responsibility to provide the
above information at the time of its completion to the DOE Office of Scientific
and Technical Information.

C.   Participant agrees to provide the above information to the University to
enable full compliance with paragraph B of this Article.

D.   It is understood that the University and the Department of Energy have a
need to document the long-term economic benefit of the cooperative research
being done under this agreement. Therefore, the Participant acknowledges a
responsibility to respond to reasonable requests, during the term of this CRADA
and for a period of three (3) years thereafter, from the University for
information relating to such economic benefit.

ARTICLE XII: PRE-PUBLICATION REVIEW

A.   The Parties agree to secure pre-publication approval from each other which
shall not be unreasonably withheld or denied beyond thirty (30) days. The
proposed publication shall be deemed not objectionable, unless the proposed
publication contains Proprietary Information, Protected CRADA Information, or
material that would create potential statutory bars to filing United States or
corresponding foreign patent applications, in which case express written
permission shall be required for publication.

B.   The Parties agree that neither will use the name of the other Party or its
employees in any promotional activity, such as advertisements, with reference to
any product or service resulting from this CRADA, without prior written approval
of the other Party.

ARTICLE XIII: COPYRIGHTS

A.   The Parties may assert copyright in any of their Generated Information.
Assertion of copyright generally means to enforce or give any indication of an
intent or right to enforce such as by marking or securing Federal registration.

B-   Each Party shall own title to copyrights in works as determined by U.S,
Copyright Law, 17 USC 101 et seq. Copyrights in jointly created works shall be
jointly owned. If either Party decides not to retain ownership of copyright in a
work created by its employee(s), that Party agrees to assign such copyright to
the other Party, at the other Party's request. Participant agrees to notify the
University if it decides not to retain ownership of copyright in any work
created by its employee(s); the University agrees to notify DOE if neither the
Participant nor the University decides to retain ownership of copyright in any
work created by their employee(s). The Parties agree to assign to the DOE, upon
request, copyrights not retained by either Party.

C.   For Generated Information, the Parties acknowledge that the Government has
for itself and others acting on its behalf, a royalty-free, non-transferable,
non-exclusive, irrevocable worldwide copyright license to reproduce, prepare
derivative works, distribute copies to the public, and perform publicly and
display publicly, by or on behalf of the Government, all copyrightable works
produced in the performance of this CRADA, subject to the restrictions this
CRADA places on publication of Proprietary Information and Protected CRADA
Information.
<PAGE>

D.   For all copyrighted computer software produced in the performance of this
CRADA, the Party owning the copyright will provide the source code, an expanded
abstract as described in Appendix B, the executable object code and the minimum
support documentation needed by a competent user to understand and use the
software to DOE's Energy Science and Technology Software Center, P.O. Box 1020,
Oak Ridge, TN 37831.

The expanded abstract will be treated in the same manner as Generated
Information in paragraph C of this Article.

E.   The University and the Participant agree that, with respect to any
copyrighted computer software produced in the performance of this CRADA, DOE has
the right, at the end of the period set forth in paragraph B of Article VIII
hereof and at the end of each two-year interval thereafter, to request the
University and the Participant and any assignee or exclusive licensee of the
copyrighted software to grant a non-exclusive, partially exclusive, or exclusive
license to a responsible applicant upon terms that are reasonable under the
circumstances, provided such grant does not cause a termination of any
licensee's right to use the copyrighted computer software. If the University or
the Participant or any assignee or exclusive licensee refuses such request, the
University and the Participant agree that DOE has the right to grant the license
if DOE determines that the University, the Participant, assignee, or licensee
has not made a satisfactory demonstration that it is actively pursuing
commercialization of the copyrighted computer software.

Before requiring licensing under this paragraph E, DOE shall furnish the
University/Participant written notice of its intentions to require the
University/Participant to grant the stated license, and the
University/Participant shall be allowed thirty (30) days (or such longer period
as may be authorized by the cognizant DOE Contracting Officer for good cause
shown in writing by the University/Participant) after such notice to show cause
why the license should not be required to be granted.

The University/Participant shall have the right to appeal the decision by the
DOE to the grant of the stated license to the Invention Licensing Appeal Board
as set forth in paragraphs (b)-(g) of 10 CFR 781.65, "Appeals."

F.   The Parties agree to place Copyright and other notices, as appropriate for
the protection of Copyright, in human readable form onto all physical media, and
in digitally encoded form in the header of machine readable information recorded
on such media such that the notice will appear in human readable form when the
digital data are off loaded or the data are accessed for display or printout.

ARTICLE XIV: REPORTING SUBJECT INVENTIONS

A.   The Parties agree to disclose to each other each and every Subject
Invention, which may be patentable or otherwise protectable under the Patent
Act. The Parties acknowledge that the University and Participant will disclose
their respective Subject Invention to the DOE within two (2) months after the
inventor first discloses the Subject Invention in writing to the person(s)
responsible for patent matters of the disclosing Party.

B.   These disclosures should be in sufficiently complete technical detail to
convey a clear understanding, to the extent known at the time of the disclosure,
of the nature, purpose and operation of the Subject Invention. The disclosure
shall also identify any known actual or potential statutory bars, i.e., printed
<PAGE>

publications describing the Subject Invention or the public use or on sale of
the Subject Invention in this country. The Parties further agree to disclose to
each other any subsequent known actual or potential statutory bar that occurs
for a Subject Invention disclosed but for which a patent application has not
been filed. All Subject Invention disclosures shall be marked as confidential
under 35 USC 205.

ARTICLE XV: TITLE TO INVENTIONS

Whereas the Participant and the University have been granted the right to elect
to retain title to Subject Inventions:

A.   Each Party shall own title to any Subject Invention made solely by its
employees or Agents. Title to jointly made Subject Inventions shall be jointly
owned. If either Party elects not to retain its interest in the title to a
Subject Invention, the other Party shall have the first option to acquire by
assignment the exclusive title to such invention. The DOE may obtain title to
any Subject Invention that is not retained by any Party.

B.   The Parties acknowledge that the DOE may obtain title to each Subject
Invention reported under Article XIV for which a patent application or
applications are not filed pursuant to Article XVI and for which any issued
patents are not maintained by any Party to this CRADA.

C.   The Parties acknowledge that the Government retains a non-exclusive, non-
transferable, irrevocable, paid-up license to practice or to have practiced for
or on behalf of the United States every Subject Invention under this CRADA
throughout the world.

The Parties agree to enter into a separate Option Agreement in which the
Participant is granted an option to obtain an exclusive license in a specified
field of use and upon mutually agreed terms and conditions to Intellectual
Property generated by University employees under this CRADA. The Parties
understand that rights in Intellectual Property generated under subcontracts for
tasks under this CRADA are treated in accordance with the terms of the
subcontracts. Accordingly, neither Party will enter into any subcontract for
tasks under this CRADA without the prior written approval of the other Party.

ARTICLE XVI: FILING PATENT APPLICATIONS

A.   The Parties agree that the Party initially indicated as having an ownership
interest in any Subject Inventions (Inventing Party) shall have the first
opportunity to file U.S. and foreign patent applications. If the Participant
does not file such applications within one year after election, or if the
University does not file such applications within the filing time specified in
its prime contract, then the other Party to this CRADA exercising an option
pursuant to Article XV may file patent applications on such Subject Inventions.
If a patent application is filed by the other Party (Filing Party), the
Inventing Party shall reasonably cooperate and assist the Filing Party, at the
Filing Party's expense, in executing a written assignment of the Subject
Invention to the Filing Party and in otherwise perfecting the patent
application, and the Filing Party shall have the right to control the
prosecution of the patent application. The Parties shall agree between
themselves as to who will file patent applications on any joint Subject
Invention.
<PAGE>

B.   The Parties agree that DOE has the right to file patent applications in any
country if neither Party desires to file a patent application for any Subject
Invention. Notification of such negative intent shall be made in writing to the
DOE Contracting Officer within three (3) months of the decision of the non-
inventing party to not file a patent application for the Subject Invention
pursuant to Article XV, or not later than 60 days prior to the time when any
statutory bar might foreclose filing of a U.S. patent application.

ARTICLE XVII: TTRADEMARKS

'Me Parties may seek to obtain Trademark/Service Mark protection on products or
services generated under this agreement in the United States or foreign
countries. Each Party shall own title -to Trademarks/Service Marks developed
solely by its employees or Agents. Jointly developed Trademarks/Service Marks
shall be jointly owned. The Parties hereby acknowledge that the Government shall
have the right to indicate on any similar goods or services produced by or for
the Government that such goods or services were derived from and are a DOE
version of the goods or services protected by such Trademark/Service Mark with
the Trademark and the owner thereof being specifically identified. In addition,
the Government shall have the right to use such Trademark/Service Mark in print
or communications media.

     independently developed by recipient's employees who did not have access to
     such Proprietary Information.

E.   In no case shall the Contractor provide Proprietary Information of

B.   The Parties agree that neither will use the name of the other Party or its
     employees in any promotional activity, such as advertisements, with
     reference to any product or service resulting from this CRADA, without
     prior written approval of the other Party.

ARTICLE XIII: COPYRIGHTS
              ----------

A.   The Parties may assert copyright in any of their Generated Information.

B.   Copyrights arising under this CRADA which are authored solely by employees
     of Participant

                                       4
<PAGE>

     shall be owned by Participant.

     Copyrights which are authored solely by employees of Contractor and which
     are obtained by Contractor shall be owned by Contractor.

     For copyrights arising under this CRADA authored by employees of both
     Parties, each Party shall have undivided rights in ownership of such
     copyrights, provided the copyrights are generated with the intention that
     the Parties' contributions be merged into inseparable or independent parts
     of a unitary whole. Jointly owned rights in copyrights shall be without
     accounting.

     For a period of up to six (6) months from the date of completion or
     termination of this CRADA, Contractor agrees to offer an option to
     Participant to negotiate a nonexclusive Copyright License Agreement for any
     Copyright arising under this CRADA and obtained by Contractor. The U.S.
     Competitiveness Clause shall apply to all such Agreements.

C.   For Generated Information, the Parties acknowledge that the Government has
     for itself and others acting on its behalf, a royalty-free,
     nontransferable, nonexclusive, irrevocable worldwide copyright license to
     reproduce, prepare derivative works, distribute copies to the public, and
     perform publicly and display publicly, by or on behalf of the Government,
     all copyrightable works produced in the performance of this CRADA, subject
     to the restrictions this CRADA places on publication of Proprietary
     Information and Protected CRADA Information.

D.   For all copyrighted computer software produced in the performance of this
     CRADA the Party owning the copyright will provide source code, an expanded
     abstract as described in Appendix B, and the object code and the minimum
     support documentation needed by a competent user to understand and use the
     software to DOE's Energy Science and Technology Software Center, P. 0. Box
     1020, Oak Ridge, TN 37831. The expanded abstract will be treated in the
     same manner as Generated Information in subparagraph C of this Article.

E.   The Contractor and the Participant agree that, with respect to any
     copyrighted computer software produced in the performance of this CRADA,
     DOE has the right, at the end of the period set forth in paragraph B of
     Article VII hereof and at the end of each two-year interval thereafter, to
     request the Contractor and the Participant and any assignee or exclusive
     licensee of the copyrighted software to grant a nonexclusive, partially
     exclusive, or sole commercial license to a responsible applicant upon terms
     that are reasonable under the circumstances, provided such grant does not
     cause a termination of any licensee's right to use the copyrighted computer
     software. If the Contractor or the Participant or any assignee or exclusive
     licensee refuses such request, the Contractor and the Participant agree
     that DOE has the right to grant the license if DOE determines that the
     Contractor, the Participant, assignee, or licensee has not made a
     satisfactory demonstration that it is actively pursuing commercialization
     of the copyrighted computer software.

     Before requiring licensing under this paragraph E, DOE shall furnish the
     Contractor/Participant written notice of its intentions to require the
     Contractor/Participant to grant the stated license, and the
     Contractor/Participant shall be allowed thirty (30) days (or such longer
     period as may be authorized by the cognizant DOE Contracting Officer for
     good cause shown in writing by the Contractor/Participant) after such
     notice to show cause why the license should not be required to be granted.

     The Contractor/Participant shall have the right to appeal the decision by
     the DOE to the grant of the stated license to the Invention Licensing
     Appeal Board as set forth in paragraphs (b)- (g) of 10 CFR 781.65,
     "Appeals".

F.   The Parties agree to place copyright and other notices, as appropriate for
     the protection of

                                       5
<PAGE>

     copyright, in human readable form onto all physical media, and in digitally
     encoded form in the header of machine readable information recorded on such
     media such that the notice will appear in human readable form when the
     digital data are off-loaded or the data are accessed for display or
     printout.

ARTICLE XIV: REPORTING SUBJECT INVENTIONS
             ----------------------------

A.   The Parties agree to disclose to each other each and every Subject
     Invention which may be patentable or otherwise protectable under the Patent
     Act. The Parties acknowledge that the Contractor will disclose all Subject
     Inventions to the DOE within two (2) months after the inventor first
     discloses the Subject Invention in writing to the person(s) responsible for
     patent matters of the disclosing Party.

B.   These disclosures should be in such detail as to be capable of enabling one
     skilled in the art to make and use the Subject Invention under 35 USC 112.
     The disclosure shall also identify any known actual or potential statutory
     bars, i.e., printed publications describing the Subject Invention or the
     public use or on sale of the Subject Invention in this country. The Parties
     further agree to disclose to each other any subsequently known actual or
     potential statutory bar that occurs for a Subject Invention disclosed but
     for which a patent application has not been filed. All Subject Invention
     disclosures shall be marked as confidential under 35 USC 205.

ARTICLE XV: TITLE TO SUBJECT INVENTIONS
            ---------------------------

Whereas DOE has granted rights to Subject Inventions to the Participant and to
the Contractor:

A.   Each Party shall have the first option to elect to retain title to any
     Subject Invention made by its employees. If a Party elects not to retain
     title to any Subject Invention of its employees, then the other Party shall
     have the second option to elect to retain title to such Subject Invention.
     The DOE shall retain title to any Subject Invention which is not retained
     by any Party. Each Party shall have the option to elect to retain title to
     its undivided rights in any Subject Invention made jointly by employees of
     Contractor and employees of Participant.

B.   The Parties acknowledge that the DOE may obtain title to each Subject
     Invention reported under Article XIV for which a patent application or
     applications are not filed pursuant to Article XVI and for which any issued
     patents are not maintained by any Party to this CRADA.

C.   The Parties acknowledge that the Government retains a nonexclusive,
     nontransferable, irrevocable, paid-up license to practice or to have
     practiced for or on behalf of the United States every Subject Invention
     throughout the world.

D.   Participant has entered into a Sole Commercial Patent License Agreement
     with Contractor having an effective date of September 30, 1996, subject to
     Participant executing this CRADA, for Contractor's Background intellectual
     Property listed in Appendix C of this CRADA in the "Licensed Field" defined
     by the use of sensors and systems in:

       (a)  Production, storage and transportation of hydrogen for use in the
            generation of power;

       (b)  Use of hydrogen in fuel cells and high yield energy storage not
            including commercial batteries;

       (c)  Safety applications in the chemical industry where hydrogen is a by-
            product of a chemical manufacturing process; and

       (d)  Safety applications in the petroleum industry.

                                       6
<PAGE>



     For a period of 1) up to six (6) months from the date of filing of any
     patent application Contractor or 2) up to six (6) months from the date of
     completion or termination of this CRADA, whichever period expires first,
     Contractor agrees to offer to license to Participant in the "Licensed
     Field" any patents or patent applications resulting from Subject Inventions
     developed under this CRADA made solely by employees of Contractor and for
     the undivided rights of Contractor in any patents or patent applications
     resulting from joint Subject Inventions developed under this CRADA made by
     employees of Contractor and employees of Participant. Such offer shall be
     effective for a period of 1) up to six (6) months from the date of filing
     of any patent application by Contractor or 2) up to six (6) months from the
     date of completion or termination of this CRADA, whichever period expires
     first. If Participant accepts such offer, Participant's existing Sole
     Commercial Patent License Agreement with Contractor in the "Licensed Field"
     shall be amended to include such patents or patent applications and to
     include the U.S. Competitiveness Clause in such Sole Commercial Patent
     License Agreement. If Participant does not accept such offer and execute
     such Sole Commercial Patent License Agreement within a period of 1) up to
     six (6) months from the date of filing of any patent application by
     Contractor or 2) up to six (6) months from the date of completion or
     termination of this CRADA, whichever period expires first, such offer will
     be withdrawn and Contractor shall be free to license such Subject
     Inventions or such joint Subject Inventions in the "Licensed Field" to any
     party. The U.S. Competitiveness Clause shall apply to all such Agreements.

ARTICLE XVI:   FILING PATENT APPLICATIONS
               --------------------------

A.   The Parties agree that the Party initially indicated as having an ownership
     interest in any Subject Inventions shall have the first opportunity to file
     U.S. and foreign patent applications; but if such Party does not file such
     applications within six (6) months after disclosure, then the other Party
     to this CRADA may file patent applications on such Subject Inventions and
     the Party initially having ownership interests shall fully cooperate in
     this effort. The Parties shall share equally in the costs for the
     prosecution, filing and maintenance of joint Subject Inventions where both
     Parties elect to retain title to their undivided rights.

B.   The Parties agree that DOE has the right to file patent applications in any
     country if neither Party desires to file a patent application for any
     Subject Invention. Notification of such negative intent shall be made in
     writing to the DOE Contracting Officer within nine (9) months after the
     initial disclosure of such Subject Invention or not later than sixty (60)
     days prior to the time when any statutory bar might foreclose filing of a
     U.S. patent application.

C.   A Party electing title or filing a patent application in the United States
     or in an foreign country shall advise the other Party and the DOE if it no
     longer desires to continue prosecution or retain title in the United States
     or any foreign country. The other Party and then the DOE will be afforded
     the opportunity to take title and retain the patent rights in the United
     States or any such foreign country.

D.   Every twelve (12) months from the date of the CRADA, each Party shall
     deliver to the other Party interim reports listing the Subject Inventions,
     if any, it has produced during the preceding twelve (12) month period. If a
     Party has produced no Subject Invention for any twelve (12) month period,
     the Party's interim report for that period will explicitly state so.

ARTICLE XVII:  TRADEMARKS
               ----------

A.   The Parties may seek to obtain Trademark/service mark protection on
     products or services generated under this CRADA in the United States or
     foreign countries. The Parties hereby acknowledge that the Government shall
     have the right to indicate on any similar goods or services produced by or
     for the Government that such goods or services were derived from and are a
     DOE version of the goods or services protected by such Trademark/service
     mark with the Trademark/service mark and the owner thereof being
     specifically identified. In

                                       7

     addition, the Government shall have the right to use such Trademark/service
     mark in print or communications media.

B.   For a period of up to six (6) months from the date of completion or
     termination of this CRADA, Contractor agrees to offer an option to
     Participant to negotiate a nonexclusive Trademark License Agreement for any
     Trademark arising under this CRADA and obtained by Contractor. The U.S.
     Competitiveness Clause shall apply to all such Agreements.

ARTICLE XVIII: MASK WORKS
               ----------

A.   The Parties may seek to obtain legal protection for Mask Works fixed in
     semiconductor products generated under this CRADA as provided by Chapter 9
     of Title 17 of the United States Code. The Parties hereby acknowledge that
     the Government or others acting on its behalf shall retain a nonexclusive,
     paid-up, worldwide, irrevocable, nontransferable license to reproduce,
     import, or distribute the covered semiconductor product by or on behalf of
     the Government, and to reproduce and use the Mask Work by or on behalf of
     the Government.

B.   For a period of up to six (6) months from the date of completion or
     termination of this CRADA, Contractor agrees to offer an option to
     Participant to negotiate a nonexclusive Mask Works License Agreement for
     any Mask Works arising under this CRADA and obtained by Contractor. The
     U.S. Competitiveness Clause shall apply to all such Agreements.

ARTICLE XIX:   COST OF INTELLECTUAL PROPERTY PROTECTION
               ----------------------------------------

Each Party shall be responsible for payment of all costs relating to copyright,
Trademark and Mask Work filing, U.S. and foreign patent application filing and
prosecution, and all costs relating to maintenance fees for U.S. and foreign
patents hereunder which are owned by that Party. Government/DOE laboratory funds
contributed as DOE's cost share to a CRADA cannot be given to Participant for
payment of Participant's costs of filing and maintaining patents or filing for
copyrights, Trademarks and Mask Works.

ARTICLE XX:    REPORTS OF SUBJECT INVENTION USE
               --------------------------------

Participant agrees to submit, upon request of DOE, a nonproprietary report no

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

The Parties acknowledge that the DOE has certain march-in rights to any Subject
Inventions in accordance with 48 CFR 27.304-1(g).

ARTICLE XXII:  U.S. COMPETITIVENESS
               --------------------

The Parties agree that a purpose of this CRADA is to provide substantial benefit
to the U.S. economy.

In exchange for the benefits received under this CRADA, the Parties therefore
agree to the following:

A.   Products embodying Intellectual Property developed under this CRADA shall
     be substantially manufactured in the United States;

B.   Processes, services, and improvements thereof which are covered by

     this CRADA to participate in or observe the research to be performed under
     this CRADA. Such personnel assigned by the assigning Party shall not during
     the period of such assignments be considered employees of the receiving
     Party for any purpose.

B.   The receiving Party shall have the right to exercise routine administrative
     and technical supervisory control of the occupational activities of such
     personnel during the assignment period and shall have the right to approve
     the assignment of such personnel and/or to later request their removal by
     the assigning Party.

C.   The assigning Party shall bear any and all costs and expenses with regard
     to its personnel assigned to the receiving Party's facilities under this

ARTICLE XXIV:  FORCE MAJEURE
               -------------

No failure or omission by Contractor or Participant in the performance of any
obligation under this CRADA shall be deemed a breach of this CRADA or create any
liability if the same shall arise from any cause or causes beyond the control of
Contractor or Participant, including but not limited to the following, which,
for the purpose of this CRADA, shall be regarded as beyond the control of the
Party in question: Acts of God, acts or omissions of any government or agency

                                     for
            Development of Low Cost Hydrogen Sensors and Detectors

Purpose and Background

The purpose of this Cooperative Research and Development Agreement (CRADA)
between Lockheed Martin Energy Research Corporation (Contractor) and DCH
Technology, Incorporated (Participant), is to develop and commercialize hydrogen
sensor prototypes for the Department of Energy (DOE) Hydrogen Program. The
Contractor and the Participant are hereinafter jointly referred to as the
"Parties". Current hydrogen sensor prototypes, developed and patented at the
Contractor are monolithic, thick-film devices that are inherently robust with
respect to temperature and humidity and cost very little to manufacture. The
sensors have demonstrated a good response to hydrogen at the lower explosive
limit and preliminary tests also indicate a fast enough response and sufficient
hardiness for many applications relevant to hydrogen production, storage, and
transport. The technical challenges that must be met to commercialize this
device involve materials optimization; detector electronics and packaging design
that enable inexpensive and reliable manufacture, as well as ease of deployment;
and comprehensive evaluation of the device performance for identified
application areas.

3.3       'Me royalty provisions of Exhibit B shall be offset by any advances
made by Licensee in the Infringement by Third Parties Section hereinbelow.
<PAGE>

3.4       Upon termination of this Agreement for any reason whatsoever, any
royalties that remain unpaid shall be properly reported and paid to LMER within
thirty (30) days of any such termination.

4 .       Records and Reports

4.1       Licensee agrees to keep adequate records in sufficient detail to

any action against the validity of the patent, Licensee shall indemnify and hold
LMER harmless against all liability, expense and costs, including attorneys'
fees incurred as a result of any such suit.
<PAGE>

6.3       Licensee may, however, apply all such costs as a reduction of any
royalties due and payable to LMER under the terms of this Agreement at such time
as verified bills of costs actually incurred are reported to LMER in accordance
with the Records and Reports Section hereinabove.

9 .       Term of Agreement and Early Termination

9.1       This Agreement shall run for a period of five (5) years from the
effective date of this Agreement subject to early termination as set forth
hereinbelow and the terms and conditions set forth in Exhibit B and Exhibit C
attached hereto and hereby incorporated into this Agreement by reference
thereto. At the end of the first five (5) year period and every five (5) year
period thereafter, LMER shall review Licensee's progress in the Development and
Commercialization plan outlined in Exhibit C and the royalty payments outlined
in Exhibit B. If said review indicates that Licensee has satisfied substantially
all the terms of the Development and Commercialization plan outlined in Exhibit
C and has paid all royalties due until the date of the review and is able to
satisfy the worldwide demand for Products, in the Licensed Field at the time of
the review, LMER shall grant an automatic extension of this Agreement for an
additional five (5) year period until the end of the life of the last-to expire
Proprietary Rights of Exhibit A, or until the time period for prosecution and
appeal on the merits for issue of all U.S. Patents on the Proprietary Rights is
exhausted at which time this Agreement is terminated. If Licensee is not able to
satisfy the Development and Commercialization plan outlined in Exhibit C at the
time of such review, the grant of the Agreement shall convert irrevocably from a
sole commercial grant to a non-exclusive grant in the same Licensed Field
maintaining the same royalty rates and annual minimum royalties as outlined in
Exhibit B of this Agreement and Article 6. Infringement by Third Parties et seq.
shall be replaced by Article 6. Infringement by Third Parties et seq. as set
forth in Exhibit D. attached hereto.

9.2       Either party shall have the right to terminate this Agreement without
judicial resolution upon written notice to the other after a breach of any
provision by the other party has gone uncorrected for sixty (60) days after the
other party has been notified in writing of such breach.

9.3       This Agreement shall terminate automatically upon the extinguishment
of all of the Exhibit A Proprietary Rights, for any reason, but only after the
time for appealing said extinguishment has expired.

9.4       The Parties agree that LMER, at its sole discretion, may immediately
terminate this Agreement upon any attempted transfer of Licensee's interest, in
whole or in part, in this Agreement to any other party, including but not
limited to any receiver, trustee, or creditor; except a transfer to a party
succeeding to substantially all of the assets of Licensee's business which
<PAGE>

relate to the subject matter of this Agreement, upon the written approval of
LMER based on verification of the scope of the transfer.

9.5       Licensee shall provide notice to LMER of its intention to file a
voluntary petition in bankruptcy or of another party's intention to file an
involuntary petition in bankruptcy for Licensee, said notice to be received by
LMER at least thirty (30) days prior to filing such a petition. Licensee's
failure to provide such notice to LMER of such intentions shall be deemed a
material, pre-petition, incurable breach of this Agreement.

9.6       Licensee agrees that this Agreement shall automatically terminate upon
any attempt by Licensee to offer Licensee's rights under this Agreement as
collateral to a third party.

9.7 Licensee may terminate this Agreement upon sixty (60) days notice to LMER
upon paying LMER all royalties due or the succeeding two years of minimum
royalties under Exhibit B which ever is the greatest.

10.       Rights of Parties After Termination

10.1      Neither party shall be relieved of any obligation or liability under
this Agreement arising from any act or omission committed prior to the effective
date of such termination.

10.2      From and after any termination of this Agreement, Licensee shall have
the right to sell any Products that Licensee had already manufactured prior to
termination, provided that all royalties and reports required hereinabove shall
be timely submitted to LMER.

10.3      From and after any termination of this Agreement, Licensee shall not
manufacture nor have manufactured any Products pursuant to this Agreement.

10.4      The rights and remedies granted herein, and any other rights or
remedies which the parties may have, either at law or in equity, are cumulative
and not exclusive of others. On any termination, Licensee shall duly account to
LMER and transfer to it all rights to which LMER may be entitled under this
Agreement.

11.       Force Majeure

11.1      No failure or omission by LMER or by Licensee in the performance of
any obligation under this Agreement shall be deemed a breach of this Agreement
or create any liability if the same shall arise from acts of God, acts or
omissions of any government or agency thereof, compliance with requests,
recommendations, rules, regulations, or orders of any governmental authority or
any office, department, agency, or instrumentality thereof, fire, storm, flood,
earthquake, accident, acts of the public enemy, war, rebellion, insurrection,

its offices located at Valencia, California, USA and Horiba, Ltd. (hereinafter
known as "Horiba, Ltd.") with its office located in Kyoto, Japan, is entered
into this 18th day of January 1999.

It is agreed as follows-

1 . Scope. Horiba, Ltd. shall serve as the exclusive representative and agent of
DCH in Japan and other Asian countries as may be identified at a later date by
agreement of both parties. Horiba, Ltd. agrees to actively market and sell
products supplied and/or manufactured by DCH in the territories covered as
agreed.

2.  Term. Horiba shall serve as the exclusive agent for DCH for a period of one
year following the date noted above. During that time, Horiba agrees to sell DCH
equipment utilizing fifty (50) sensors. Should Horiba meet its goal of selling
the indicated number of sensors, this contract will automatically be extended
for a period of five years from the date noted above. Should Horiba be
unsuccessful in selling sell DCH equipment utilizing fifty (50) sensors in the
one year period, DCH and Horiba agree to negotiate in good faith to determine
the best course of action to follow. For the purposes of this agreement, a
"sale" is described as an order from Horiba to DCH Technology that (1) has been
received by DCH, (2) are for product that has been, or will be, delivered by DCH
to Horiba and (3) has been or will be paid by Horiba within 30 days of receipt
of the products ordered. Orders that are subsequently cancelled by Horiba will
not be considered "sales" for the purposes of this agreement.

In addition to the above, DCH agrees to sell its standard products (such as the
Hand Held Unit) to Horiba for resale at a special discount of 33% off the DCH
list price.
For example, if the DCH list price is $3,500.00, DCH will sell the product to
Horiba for $2,345.00.
DCH will also provide favorable OEM pricing to Horiba for "integration kits"
which consist of DCH hardware.

It should be noted that both parties are desirous of succeeding in this market
place and both parties view this as a potentially significant opportunity.
Therefore, both parties agree that each will take whatever reasonable action
might be necessary to attain success.

3.  Non-compete and Confidentiality. Both parties agree not to compete directly
or indirectly with one another in the sensor market in the territories noted
above. Both parties (DCH and Horiba, Ltd.) agree to exchange proprietary
information (and label this as "Proprietary" or "Confidential") as necessary and
not to disseminate this information without the prior, written consent of the
other party. Both parties agree to protect each others' confidential information
with the same care they use to protect their own.
<PAGE>

4. Support. DCH agrees to provide all necessary support including, but not
limited to, brochures, data sheets, training, service and warranty
administration and hereby authorizes Horiba, Ltd. to provide such data and
services locally.

set forth therein, and (ii) eighty percent (80%) to the Members in proportion to
the number of Units held by each Member.

B.   Schedule B may be amended from time to time by the Board of Managers in its
sole and absolute discretion. With respect to any person whose name appears in
Schedule B, the Company, its Officers, and Directors shall have no liability
arising out of the deletion of such person's name from Schedule B or the
modification of such person's percentage of distributions as set forth therein,
and the appearance of any person's name in Schedule B and the designation of
such percentage shall create no right or presumption of membership in such
person in the Company or of employment in such person with the Company and no
right to, expectation of, or presumption regarding any distributions by the
Company with respect to such person, other than distributions in accordance with
the provisions of this Section 4.1. Notwithstanding any provision contained
herein to the contrary, to the extent the amount of distributions in any given
calendar year is insufficient to cover the tax liability of any Member arising
out of such person or entity's being a Member of the Company, the Board of
Managers shall cause the Company to distribute Available Cash to such Member to
make up the deficit.

C.    Notwithstanding Section 4.1.A, if the Available Cash is produced by a
Capital Transaction, the eighty percent (80%) of Available Cash not distributed
to the Management Team listed on Schedule B shall be distributed as follows:

(i)   First, to the holders of the Class A Units, in the amount of and in
proportion to their respective amounts of Invested Capital; and

previously allocated to such Members pursuant to Section 4.2.B(i) and not
previously reversed by an allocation of profits under this Section 4.2.A(i);

(ii)  Second, the balance of profits, if any, to the Members, in proportion to
the number of Units held by each Member.

B.    Loss shall be allocated among the Members in the following order:

(i)   First, to the Members in proportion to and in the amount of their positive
Capital Account balances; and

(ii)  Second, the balance of loss, if any, to the Members, in proportion to the
number of Units held by each Member.

Section 4.3    Allocation of Taxable Income and Taxable Loss.

A.    Except as may be otherwise required under the Code or the applicable

B.    In accordance with Code Section 704(c) and the Treasury Regulations
thereunder, income, gain, loss, and deduction with respect to any property
contributed to the capital of the Company shall, solely for tax purposes, be
allocated among the Members so as to take account of any variation between the
adjusted basis of such property to the Company for federal income tax purposes
and its initial fair market value (as used by the Company as the book value of
the property).

C.    In the event the book value of any Company property is adjusted upon: (i)
acquisition of Units by any person in exchange for a Capital Contribution, (ii)
any non-pro rata distribution to Members of Company property other than cash, or
(iii) a termination of the Company for federal income tax purposes under Code
Section 708(b)(1)(B), subsequent allocation of income, gain, loss, and deduction
with respect to such asset shall take account of any variation between the
adjusted basis of such asset for federal income tax purposes and its book value
in accordance with Code Section 704(c) and the Treasury Regulations thereunder,
using such method as may be determined by the Board of Directors.

D.    Allocations pursuant to Section 4.3.B and 4.3.C are solely for purposes of
federal, state, and local taxes and shall not affect, or in any way be taken
into account in computing, any Member's Capital Account or share of profits or
loss, other items, or distributions pursuant to any provision of this Agreement.
<PAGE>

Section 4.4    Distributions Upon Dissolution and Termination.

Upon the dissolution and termination of the Company, the assets remaining after
satisfaction (whether by payment or by establishment of reserves therefor) of
creditors, including Members who are creditors, shall be distributed to the
Members in accordance with the positive balances in their respective Capital
Accounts, subject to the provisions of Section 8.2 below. If assets are to be
distributed in kind, the Members' Capital Accounts shall be appropriately
adjusted, in accordance with Section 4.2, before any such distribution to
reflect any profits and losses which would have been allocated if the property
distributed in kind had been sold for its fair market value (net of liabilities)
by the Company prior to dissolution.

Section 4.5    No Deficit Restoration Obligation.

No Member shall be obligated to contribute additional capital to the Company in
order to restore a deficit balance in such Member's Capital Account except to
the extent of a negative capital account caused by a Member's receipt of
distributions of Available Cash in excess of the profits allocated to such
Member net of the losses allocated to such Member, except to the extent that
such deficit Capital Account results from the Member's receipt of Available cash
in excess of the aggregate profits (reduced by aggregate losses) allocated to
such Member.

Section 5.8     Mandatory Buy-Sell Procedures.

A.      The Buy-Sell Procedures may be initiated by any Member upon the
occurrence of a Management Deadlock. A "Management Deadlock" shall be deemed to
have occurred if (x) a Manager brings an issue to the Board of Managers to be
voted on within ten (10) days after its introduction and a resolution of the
issue is not obtained because a majority of Managers cannot agree or because one
or two of the Managers refuse(s) to vote on the issue; and (y) the same issue is
brought to the Board of Managers on one additional occasion and, on such
occasion, no resolution of the issue is obtained. The Member initiating the Buy-
Sell Procedures shall be referred to herein as the "Offering Member" and the
Member(s) other than the Offering Member shall be referred to herein as the
"Offeree Member."

B.      In order to initiate the Buy-Sell Procedures, the Offering Member shall
deliver written notice (the "Buy-Sell Notice") to the Offeree Member stating
that the Offering Member intends to initiate the Buy-Sell Procedures and the
amount that the Offering Member is willing to pay as the purchase price for all
of the Offeree Member's Units (the "Offer Price"). Upon receipt of the Buy-Sell
Notice, the Offeree Member shall have the option either:

(i)     To elect to sell all of its Units to the Offering Member for an amount
equal to the Offer Price (with the Offer Price to be divided among the Offeree
Members in proportion to their respective Percentage Interests if more than one
Offeree Member); or

(ii)    To elect to purchase all of the Units of the Offering Member for an
amount equal to the Offer Price.

C.      The Offeree Member shall have sixty (60) days from the date of the Buy-
Sell Notice to notify the Offering Member of its election hereunder. If the
Offerce Member fails to notify the Offering Member of its election within said
sixty (60) days, then, as of the day following the expiration of such 90-day
period, the Offeree Member shall be conclusively deemed to have elected to sell
all, but not less than all, of its Units to the Offering Member at the Offer
Price.

D.      If, following an election by the Offeree Member to purchase all of the
Units of the Offering Member 'or to sell all of its Units to the Offering
Member, such purchase does not close due to the fault of the Member obligated to
sell its Units, from and after the date fixed for such closing, the defaulting
Member shall have no further rights or interests under this Agreement or in the
Company other than to receive the purchase price required hereunder.

E.      The closing of the sale of a Member's Units pursuant to this Section 5.8
shall be held at the principal office of the Company, or at such other place as
agreed to in writing by the parties, and shall occur within ninety (90) days
following the date on which the selling Member becomes bound
<PAGE>

to this Section 5.8.

extent permitted or authorized by the laws of the State of Maryland now or
hereafter in force applied as if the Company were a Maryland corporation,
including (without limitation) the advance of expenses under the procedures and
to the full extent permitted by law, and (ii) other employees and agents of the
Company to such extent as shall be authorized by the Board of Managers and is
permitted by law. The foregoing rights of indemnification shall not be exclusive
of any other rights to which those seeking indemnification may be entitled. The
Board of Managers may take such action as is necessary to carry out these
indemnification provisions and is expressly empowered to adopt, approve and
arnend from time to time such resolutions or contracts implementing such
provisions or such further indemnification arrangements as may be permitted by
law. No amendment of the Articles of Organization or this Agreement or repeal of
any of the provisions thereof shall limit or eliminate the right to
indemnification provided hereunder with respect to acts or omissions occurring
prior to such amendment or repeal. The indemnification shall be payable solely
from the assets of the Company and no Member shall have any personal or
corporate liability therefor.

B.      To the fullest extent permitted by Maryland statutory or decisional law,
as amended or interpreted, no Manager or Officer of the Company shall be
personally liable to the Company or any Members for money damages. No amendment
of the Articles of Organization or this Operating Agreement, or repeal of any of
their respective provisions, shall limit or eliminate the limitation on
liability provided to Managers and Officers hereunder with respect to any act or
omission occurring prior to such amendment or repeal.

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

Section 6.1     Transfer of Units.

No Member shall Transfer all or any part of such Member's Units, except upon
receiving the prior written consent of the Board of Managers and each other
Member, which consent may be withheld for any reason, or otherwise in accordance
with the terms of this Agreement.

Section 6.2     Right of First Refusal; Tag-Along and Drag- Along.

If any Member (in this capacity, a "Selling Member") desires to engage in a
Transfer of all or any portion of its Units (the " Transferable Units") by any
means whatsoever, he shall first comply with the following:

A.      Notice. The Selling Member shall give written notice (the "Selling
Member Is Notice") to the other Member(s), (singularly and collectively, the "
Offeree Member") stating the date thereof, the number of Transferable Units, the
percentage of the total number of Units owned by the Selling
<PAGE>

Member represented by the Transferable Units (the "Applicable Percentage"), and
the ten-ns and conditions of the proposed Transfer including, without
limitation, the name and address of the proposed transferee, and the price, if
any, per Transferable Units (the "Notice Price") offered by the proposed
transferee.

B.      Right of Purchase; Tag-Along. The Offeree Member shall have the right
and option to:

(i)    purchase all or any of the Transferable Units or
(ii)   require the proposed transferee to purchase no greater than the
Applicable Percentage of the Offeree Member's Units ("tag-along rights")

on the same terms as the proposed Transfer, subject to Section 6.2(E) below. The
Offeree Member's option may be exercised only in writing delivered to the
Selling Member within fifteen (15) days after the date of the Selling Member's
Notice, stating the number of Transferable Units which the Offeree Member
desires to purchase (if proceeding under B(i) of this paragraph) or the number
of the Offeree Member's Units that the Offeree Member desires to sell (if
proceeding under B(ii) of this paragraph). Any Transfer of Units under this
Section 6.2(B) shall be consummated within ninety (90) days after the date of
the Selling Member's Notice.

C.      Sale to Proposed Transferee. If all of the Transferable Units are not
purchased by the Offeree Member or if the Offeree Member has not exercised its
tag-along rights, then the Selling Member may take either or both of the
following actions:

(i)    transfer such unpurchased Transferable Units to the proposed transferee
(ii)   require the Offeree Member to tender to the proposed transferee the
Applicable Percentage of the Offeree Member's Units

all on terms not more favorable to the proposed transferee than those described
to the Offeree Member in the Selling Member's Notice and subject to the
remaining provisions of this Agreement; provided, however, that the proposed
transferee shall become a party to this Agreement.

D.      Re-offer on Failure to Sell. If the Selling Member fails to consummate a
Transfer to the proposed transferee on the terms and conditions set forth in the
Selling Member's Notice within ninety (90) days after the date of the Selling
Member's Notice, then no Transfer of Transferable Shares may be made thereafter
to the proposed transferee or to any other transferee without again complying
with the provisions of this Section 6.2.

E.      Purchase Price; Sale Price. The per Unit purchase price for any Units
purchased by the Offeree Member under this Section 6.2 shall be equal to the
lesser of. (i) the per Unit Fair Market Value multiplied by ninety percent
(90%); and (ii) if the proposed Transfer is a sale, the Notice Price. The per
Unit sale price for any Units sold by the Offeree Member under this Section 6.2
shall be equal to the greater of. (i) the per Unit Fair Market Value; and (ii)
if the proposed Transfer is a sale, the Notice Price.

Section 6.3     Option Upon Involuntary Transfer.
<PAGE>

If any Units are transferred by operation of law to any person other than a
Member, or if (a) any Member shall be adjudicated as bankrupt or make an
assignment for the benefit of creditors; (b) bankruptcy proceedings in which a
Member is alleged to be insolvent or unable to pay its debts as they mature are
instituted by or against it, and the Member consents thereto or admits in
writing the material allegations of the petitions filed in those proceedings;
(c) a Member's Units are attached; (d) any judgment is obtained in any legal or
equitable proceeding against a Member and the sale of its Units is contemplated
or threatened under legal process as a result of that judgment; (e) any
execution process is issued against a Member's Units; or (f) any other form of
legal proceeding or process is instituted by which a Member's Units may be sold
or transferred voluntarily or involuntarily and the same remains undismissed for
sixty (60) days, then such transfer or event shall be deemed to be the giving of
a Selling Member's Notice under Section 6.2(A) hereof, whereupon the Offeree
Member may purchase such Units or exercise tag- along rights upon the same terms
as set forth in Section 6.2.

Section 6.4     Effect of Bankruptcy, Dissolution or Termination of a Member.

The bankruptcy, dissolution, liquidation or termination of a Member shall not
cause the termination or dissolution of the Company and the business of the
Company shall continue. Except as otherwise provided in this Article 6, (i) upon
any such occurrence, the trustee, receiver, executor, administrator, committee
or conservator of such Member shall have all the rights of such Member for the
purpose of settling or managing its estate or property; and (ii) the Transfer by
such trustee, receiver, executor, administrator, committee or conservator of any
Member of any Units shall be subject to all of the restrictions hereunder to
which such Transfer would have been subject if such Transfer had been made by
such bankrupt, dissolved, liquidated or terminated Member.

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

Section 7.1     DCH's Initial Capital Contribution.

DCH represents and warrants that all of the shares of common stock of DCH that
comprise the initial Capital Contribution of DCH (the "Shares") were validly
issued and are fully paid and nonassessable and are being issued to the Company
pursuant to one or more valid exemptions from registration under the Securities
Act of 1933 (the "Securities Act") and pursuant to similar state exemptions from
state registration requirements (collectively, the "Securities Laws"); that DCH
has made all filings, if any, required by the Securities Laws in connection with
the issuance of the Shares; and that DCH is not subject to the reporting
requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934. The
Company represents and warrants that it is acquiring the Shares for its account
for investment and not with a view to any public resale or other distribution
thereof, and that it has received, or has had access to, all information which
it considers necessary or advisable to enable it to make a decision concerning
its acceptance of the Shares.

Section 7.2     Piggyback and Demand Registration Rights.
<PAGE>

A.      If DCH at any time proposes to register any of its securities under the
Securities Act for sale to the public, whether for its own account or for the
account of other security holders or both (other than offerings pursuant to
employee plans, or noncash offerings in connection with a proposed acquisition,
exchange offer, recapitalization or similar transaction), DCH will give written
notice thereof to the Company not less than 30 days prior to the filing of its
registration statement and will, at DCH's sole expense, include in such
registration all Shares with respect to which the Company requests in writing to
be so included within 20 days after the receipt of DCH's notice. If such
registration is subject to underwriter cutbacks, then the Shares that the
Company proposes to sell shall be included in such registration in preference to
all other securities of DCH.

the Company may request DCH to register under the Securities Act all or any
portion of the Shares held by the Company for sale in the manner specified in
such notice. Following receipt of any notice under this Section 7.2(B), the
Company shall use its best efforts to register under the Securities Act, for
public sale in accordance with the method of disposition specified in such
notice from the Company, the number of Shares specified in such notice. If such
method of disposition shall be an underwritten public offering, the Company may
designate the managing underwriter of such offering, subject to the approval of
the Company, which approval shall not be unreasonably withheld or delayed. DCH
shall be obligated to register Shares pursuant to this Section 7.2(B) on two
occasions only, provided, however, that such obligation shall be deemed
satisfied only when a registration statement covering all Shares specified in
notices received as aforesaid, for sale in accordance with the method of
disposition specified by the Company, shall have become effective and, if such
method of disposition is a firm commitment underwritten public offering, all
such Shares shall have been sold thereto. Except for registration statements on
Form S-4, S-8 or any successor thereto, DCH will not file with the Securities
and Exchange Commission any other registration statement with respect to its
common stock, whether for its own account or that of other stockholders, from
the date of receipt of a notice from the Company pursuant to this Section 7.2(B)
until the completion of the period of distribution of the registration
contemplated thereby.

Section 7.3     Payment for Services.

Until determined otherwise by the Board of Managers, the Company will have no
employees. Services provided by the Members to the Company will be billed on an
hourly rate in accordance with any terms and subject to any conditions adopted
by the Board of Managers and agreed to by the respective Members (in their
capacities not as Members but as the other parties to such agreements). Except
as explicitly provided in this Agreement, no Member or Manager, in its capacity
as such, shall receive any fee, salary, reimbursement, or other compensation or
remuneration for serving as a Member or Manager.

this Lease, however, (including but not limited to the obligations to pay

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

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

<PAGE>

(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 attar 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 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

amount of the deficiency within ten (10) days after delivery by Lessor to Lessee
of said statement.

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. It 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.

neighboring premises or properties.

any written request by Lessee, Lessee's assignees or subtenants, and by
prospective assignees and subtenants of Lessee, its assignees and subtenants,

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,

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

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 govern- mental 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).

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

environmental conditions on, in, under or about the Premises, including soil and
groundwater conditions, and (iii) the use, generation, manufacture, production,

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.

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 other- wise
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
<PAGE>

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.

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 oy 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. It the parties insert a dollar amount in Paragraph
1.9, such amount shall be considered the "Base Premium." 1f a dollar amount has
not been inserted in Paragraph 1.9 and if the Building has been previously
occupied during the twelve (1 2) month period immediately preceding the
Commencement Date, the "Base Premium" shall be the annual premium applicable to
such twelve (12) month period. It 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.
<PAGE>

8.3     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 'he coverage is available and commercially
appropriate, Lessor's policy or policies shall insure against at; 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

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, it any, otherwise

include any deductible amount in the event of such loss.

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

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

8.4 Lessee's Property Insurance. Subject to the requirements of Paragraph 8.5,
Lessee at its cost shall either by separate policy or, at Lessor's option, by
endorsement to a policy already carried, maintain insurance coverage on all of
<PAGE>

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 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 t>e insured against under Paragraph S. The off act of such
releases and waivers of the right to recover damages shall not be limited by the
amount of insurance carded 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 indemnity, 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,

with, the occupancy of the Premises by Lessee, the conduct of Lessee's business,
any art, 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 fore- going shall include, but not be limited to, the defense or

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.

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

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.

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 earth- quake
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
writ- ten 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 with- in 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


<PAGE>

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.

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

(b)  If Lessor shall be obligated to repair or restore the Premises under the
provisions o. this Paragraph 9 and shall not commence, in a substan a and ment
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. It
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 affect. "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
<PAGE>

Lessor's option either (i) investigate and remediate such Hazardous Substance
Condition, if required, as soon as reasonably possible at Lessor's expense, ii
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

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 per- cent

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 relocation. at whichever time said Not 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 a-ler 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 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 beat 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 'n 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.

limited to compensatory damages and/or injunctive relief.

12.2 Terms and Conditions Applicable to Assignment and Subletting.

person other than Lessee pending approval or disapproval of an assignment.

any of the terms, covenants or conditions of !his 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

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 pe,Fons from liability under
this Lease or the sublease.

Lease, Lessor may proceed directly against Lessee, any Guarantors or any- one
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 subleases, including but not limited to the intended use and/or

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

Lessor with such other or additional information and/or documentation as may be
reasonably requested by Lessor.

formed 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-tbe-dghL-(but not the obligation) to require that the Security Deposit be
increased by an amount equal to six (6) times the tokamak and Lessor may make
the actual receipt by Lessor of the Security Deposit Increase a condition to
Lessor's consent to such transaction.
<PAGE>

(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

adjustment schedule for property similar to the Premises as then constituted, as
determined by Lessor.

12.3    Additional Terms and Conditions Applicable to Subletting. The following
terms and conditions shall apply to any subletting by Lessee of all or any part
of the Premises and shall be deemed included in all subleases under this Lease
whether or not expressly incorporated therein:

(a)  Lessee hereby assigns and transfers to Lessor all of Lessee's interest in
all rentals and income arising from any sublease of all or a portion of the
Premises heretofore or hereafter made by Lessee, and Lessor may collect such
rent and income and apply same toward Lessee's obligations under this Lease;
provided, however, that until a Breach (as defined in Paragraph 13.1) shall
occur in the performance of Lessee's obligations under this Lease, Lessee may,
except as otherwise provided in this Lease, receive, collect and enjoy the rents
accruing under such sublease. Lessor shall not, by reason of the foregoing
provision or any other assignment of such sublease to Lessor, nor by reason of
the collection of the rents from a subleases, 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
subleases 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 sub- lessee 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 Lessors prior written consent.
(e) Lessor shall deliver a copy of any notice of Default or Breach by Lessee to

13. Default; Breach; Remedies.

                                      53
<PAGE>

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

                                      54
<PAGE>

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 (a) 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

                                      55
<PAGE>

this Lease. The worth at the time of award of the amount referred to in
provision (iii) of the immediately preceding sentence shall be computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco or the Federal Reserve Bank District in which the Premises are located
at the time of award plus one percent (1%). Efforts by Lessor to mitigate
damages caused by Lessee's Default or Breach of this Lease shall not waive
Lessor's right to recover damages under this Paragraph 13.2. If termination of
this Lease is obtained through the provisional remedy of unlawful detainer,
Lessor shall have the right to recover in such proceeding the unpaid rent and
damages as are recoverable therein, or Lessor may reserve the right to recover
all or any part thereof in a separate suit for such rent and/or damages. If a
notice and grace period is required under Subparagraph 13.1 (b), (c) or (d) was
not previously given, a notice to pay rent or quit, or to perform or quit, as
the case may be, given to Lessee under any statute authorizing the forfeiture of
leases for unlawful detainer shall also constitute the applicable notice for
grace period purposes required by Subparagraph 13.1 (b),(c) or (d). In such
case, the applicable grace period under the unlawful detainer statue 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
limi-tations on assignment and subletting in this Lease are reasonable. Acts of
maintenance or preservation, efforts to relat 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 allect, 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,
are 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 def)rned a waiver by Lessor of the provisions of

                                      56
<PAGE>

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 lim4ed to, processing
and accounting charges, and late charges which may be imposed upon Lessor by the
terms of any ground lease, mortgage or dead of trust.@tovering 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 tan (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 thereafterdiii- gently 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

                                      57
<PAGE>

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

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

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, adornment and/or non-disturbance agreement
as is provided for herein.

here- after 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,

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

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

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 lessor interest, shall constitute Lessor's election to have such
event constitute the termination of such interest.

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

reason-able with reference to the particular matter for which consent is being
given.

<PAGE>

and all of the following terms and conditions:

(1)    In order to exercise an option to extend, Lessee must give written notice
of such election to Lessor and Lessor must receive the same at least 6 but not
more than 9 months prior to the date that the option period would commence, time

as follows, using the method(s) indicated below: (Check Method(s) to be Used and
Fill in Appropriately)

1. Cost of Living Adjustment(s) (COLA)

a. On (Fill in COLA Dates): June 1, 2002, June 1, 2004, June 1, 2005 and at the

A.I.a. above during which the adjustment is to take effect, and the denominator
of which shall be the GPI of the calendar month which is two months prior to MRV

hereunder, but in no event, shall any such new rent be less than the rent
payable for the month immediately preceding the rent adjustment.

C. In the event the compilation and/or publication of the CPI 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 CPI shall be used to
make such calculation. In the event that the Parties cannot agree on such
alternative index, then the matter shall be submitted for decision to the

Association and the decision of the arbitrators shall be binding upon the
parties. The cost of said Arbitration shall be paid equally by the Parties.

decision of a majority of the arbitrators shall be binding on the Parties. The
submitted MRV which is determined to be the closest to the actual MRV shall
thereafter be used by the Parties.
(111) If either of the Parties falls to appoint an arbitrator within the
specified fifteen days, the arbitrator timely appointed by one of them shall
reach a decision on his or her own, and said decision shall be binding on the
Parties.

this Lease, however, (including but not limited to the obligations to pay

<PAGE>

(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

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 attar the expiration of each calendar year a reasonably detailed

reason thereof. It Lessor uses or applies all or any portion of said Security
Deposit, Lessee shall within ten (10) days after written request therefore

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

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

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.

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

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 oy 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. It the parties insert a dollar amount in Paragraph
1.9, such amount shall be considered the "Base Premium." 1f a dollar amount has
not been inserted in Paragraph 1.9 and if the Building has been previously
occupied during the twelve (1 2) month period immediately preceding the
Commencement Date, the "Base Premium" shall be the annual premium applicable to
such twelve (12) month period. It 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.

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 'he coverage is available and commercially
appropriate, Lessor's policy or policies shall insure against at; 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

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, it any, otherwise

include any deductible amount in the event of such loss.

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

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

8.4 Lessee's Property Insurance. Subject to the requirements of Paragraph 8.5,
Lessee at its cost shall either by separate policy or, at Lessor's option, by
endorsement to a policy already carried, maintain insurance coverage on all of
<PAGE>

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 Early Possession Date-or the Commencement Date, certified

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 t>e insured against under Paragraph S. The off act of such
releases and waivers of the right to recover damages shall not be limited by the
amount of insurance carded 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 indemnity, protect, defend and hold harmless the

Lenders, from and against any and all claims, loss of rents and/or damages,

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 fore- going shall include, but not be limited to, the defense or

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

such claim In order to be so indemnified.

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

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 earth- quake
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

(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
writ- ten 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 with- in the times specified above, this Lease
shall terminate as of the date specified in Lessor's notice of termination.

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
<PAGE>

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.

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

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. It
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 affect. "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

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

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

curable a-ler 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 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 beat 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 'n 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.

be effective without the express written assumption by such assignee or
sublessee of the obligation- 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 '.or the Default or Breach by Lessee of
any of the terms, covenants or conditions of !his 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 @nay 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 pe,Fons from liability under
this Lease or the sublease.

(d) In the event of any Default or Breach of Lessee's obligation under this
Lease, Lessor may proceed directly against Lessee, any Guarantors or any- one
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 subleases, 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 IF 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 heroin to be observed or per-
formed 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-tbe-dghL-(but not the obligation) to require that the Security Deposit be
increased by an amount equal to six (6) times the tokamak and Lessor may make
the actual receipt by Lessor of the Security Deposit Increase a condition to
Lessor's consent to such transaction.
<PAGE>

(h) Lessor, as a condition to giving its consent to any assignment or
subletting, may require that the amount and adjustment schedule of the rent

payable under this Lease be adjusted to what is then the market value and/or
adjustment schedule for property similar to the Premises as then constituted, as
determined by Lessor.

12.3    Additional Terms and Conditions Applicable to Subletting. The following
terms and conditions shall apply to any subletting by Lessee of all or any part
of the Premises and shall be deemed included in all subleases under this Lease
whether or not expressly incorporated therein:

(a)  Lessee hereby assigns and transfers to Lessor all of Lessee's interest in
all rentals and income arising from any sublease of all or a portion of the
Premises heretofore or hereafter made by Lessee, and Lessor may collect such
rent and income and apply same toward Lessee's obligations under this Lease;
provided, however, that until a Breach (as defined in Paragraph 13.1) shall
occur in the performance of Lessee's obligations under this Lease, Lessee may,
except as otherwise provided in this Lease, receive, collect and enjoy the rents
accruing under such sublease. Lessor shall not, by reason of the foregoing
provision or any other assignment of such sublease to Lessor, nor by reason of
the collection of the rents from a subleases, 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
subleases 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 sub- lessee 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 Lessors 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.

<PAGE>

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

<PAGE>

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 (a) 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

<PAGE>

this Lease. The worth at the time of award of the amount referred to in
provision (iii) of the immediately preceding sentence shall be computed by
discounting such amount at the discount rate of the Federal Reserve Bank of San
Francisco or the Federal Reserve Bank District in which the Premises are located
at the time of award plus one percent (1%). Efforts by Lessor to mitigate
damages caused by Lessee's Default or Breach of this Lease shall not waive
Lessor's right to recover damages under this Paragraph 13.2. If termination of
this Lease is obtained through the provisional remedy of unlawful detainer,
Lessor shall have the right to recover in such proceeding the unpaid rent and
damages as are recoverable therein, or Lessor may reserve the right to recover
all or any part thereof in a separate suit for such rent and/or damages. If a
notice and grace period is required under Subparagraph 13.1 (b), (c) or (d) was
not previously given, a notice to pay rent or quit, or to perform or quit, as
the case may be, given to Lessee under any statute authorizing the forfeiture of
leases for unlawful detainer shall also constitute the applicable notice for
grace period purposes required by Subparagraph 13.1 (b),(c) or (d). In such
case, the applicable grace period under the unlawful detainer statue 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
limi-tations on assignment and subletting in this Lease are reasonable. Acts of
maintenance or preservation, efforts to relat 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 allect, 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,
are 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 def)rned a waiver by Lessor of the provisions of

<PAGE>

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 lim4ed to, processing
and accounting charges, and late charges which may be imposed upon Lessor by the
terms of any ground lease, mortgage or dead of trust.@tovering 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 tan (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 thereafterdiii- gently 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

<PAGE>

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 not severance
damages required to complete such repair. 15. Brokers' Fees.

negotiation of this Lease and/or the consummation of the transaction
contemplated hereby, and that no broker or other person, firm or entity other
than said named Broker(s) is entitled to any commission or finder's fee in
connection with said transaction. Lessee and Lessor do each hereby agree to
indemnity, protect, defend and hold the other harmless from and against
liability for compensation or charges which may be claimed by any such unnamed
broker, finder or other similar party by reason of any dealings or actions of
the indemnifying Party, including any costs, expenses, and/or attorneys' fees
reasonably incurred with respect thereto.

16. Tenancy and Financial Statements.

16.1    Tenancy Statement. Each Party (as "Responding Party") shall within ten

statements for the past three (3) years. All such financial statements shall be

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

the Lessor shall be binding only upon the Lessor as hereinabove defined.

18.  Severablility. The invalidity of any provision of this Lease, as determined

other provision hereof.

19.  Interest on Past-Due Obligations. Any monetary payment due Lessor

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%)_pp@rqr)nurn, but not exceeding
the maximum rate allowed by law, in addition to the potential late charge
provided for in Paragraph 13.4.

of this Lease are deemed to be rent.

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,

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 doomed to ronder 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.  This Paragraph has been intentionally omitted.-

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; Attarnment; Non-Disturbance.

<PAGE>

30.1   Subordination. This Lease and any Option granted hereby shall be subject
and subordinate to any ground lease, mortgage, dead 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 owner- ship
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, adornment 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
here- after 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.

<PAGE>

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, atid 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 applciable signage criteria established by 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 lessor 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 lessor 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

<PAGE>

Security Deposit hold 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
reason- able 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

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

hereinafter by DECLARANT acting for itself or as DECLARANT acting as trustee, on
behalf of all of the Owners of Sites. Each Owner by acquiring an interest in a
Site shall appoint irrevocably the DECLARANT as its attorney-in-fact for such
purposes; provided, however that if an Owner of a Site notified DECLARANT of a
claimed violation of these conditions, covenants, restrictions and reservations
in writing and DECLARANT fails to act within sixty (60) days after receipt of
such notification, then, and in that event only, an Owner may separately, at its
own cost and expense, enforce the conditions, covenants, restrictions and
reservations herein contained and have all of the remedies provided for in
Section 7.2 hereafter.

SECTION 7.2 DEFAULT ANID REMEDIES

equity, whether or not set forth herein. All remedies provided for herein or by
law or in equity shall be cumulative and not mutually exclusive.
<PAGE>

foregoing restrictions may cause DECLARANT to suffer material injury or damage
not compensable in money and that DECLARANT shall be entitled to bring an action
in equity or otherwise for specific performance to enforce compliance with the
VALENCIA INDUSTRIAL CENTER RESTRICTIONS or an injunction to enjoin the
continuance of any such breach or violation thereof.

C. ABATEMENT AND LIEN RIGHTS Any such breach or violation of the VALENCIA
INDUSTRIAL CENTER RESTRICTIONS or any provision hereof is hereby declared to be
a nuisance, and DECLARANT shall be entitled to enter the Site or any portion
thereof as to which the breach or violation exists and summarily abate and
remove, without further legal process to the maximum extent permitted by law,
any structure, thing or condition that may exist in violation of any of the
VALENCIA INDUSTRIAL CENTER RESTRICTIONS, or to prosecute any remedy allowed by
law or equity for the abatement of such nuisance against any person or entity
acting or failing to act in violation of the VALENCIA INDUSTRIAL CENTER
RESTRICTIONS, all at the sole cost and expense of Owner or any person having
possession under Owner. Any costs or expenses paid or incurred by DECLARANT in
abating such nuisance or prosecuting any such remedy (including all reasonable
attorneys' fees and costs of collection), together with interest thereon at the
maximum rate permitted by law shall be a charge against the Site or any portion
thereof as to which the breach or violation exists, shall be a continuing lien
thereon until paid, and shall also be the personal obligation of that person or
entity who was Owner when such charges became due and committed such breach or
violation. In addition to any other rights or remedies hereunder, DECLARANT may
deliver to Owner and record with the Los Angeles County Recorder a certificate
or notice to claim of lien (which, among other things may but need not recite
the nature of the violation, the legal description of the Site or portion
thereof affected by such violation, the record or reputed Owner thereof,
DECLARANT'S name and address, and the remedies being pursued or the amount of
any such claim being changed). If the violation recited in such lien claim has
not been cured to DECLARANT'S satisfaction and any recited amounts so charged
have not been paid within 30 days thereafter, DECLARANT or DECLARANT'S
authorized representatives may foreclose such lien by a sale conducted pursuant
to Sections 2924, 2924b, and 2924c of the California Civil Code, as amended from
time to time, or such other statutes applicable to the exercise of powers of
sale in mortgages or deeds of trust, or in any other manner permitted by law.
DECLARANT, through its authorized representatives, may bid on and acquire any
Site or portion thereof subject to such lien at any such foreclosure sale. If
the violations recited in such lien claim are timely cured and any recited
amounts timely paid as provided above, an appropriate release of such lien shall
be recorded by DECLARANT at Owner's sole cost and expense.

SECTION 7.3 WAIVER

No waiver by DECLARANT of a breach of any of the VALENCIA INDUSTRIAL CENTER
RESTRICTIONS and no delay or failure to enforce any of the VALENCIA INDUSTRIAL
CENTER RESTRICTIONS shall be construed or held to be a waiver of any succeeding
or preceding breach of the same or any other of the VALENCIA INDUSTRIAL CENTER
RESTRICTIONS by that Owner of any other Owner of the Site, or any other Site. No
waiver by DECLARANT of any breach or default hereunder shall be implied from any
omission by DECLARANT to take any action on account of such breach or default if
<PAGE>

such breach or default persists or is repeated, and no express waiver shall
affect a breach or default other than as specified in said waiver. The consent
or approval by DECLARANT to or of any act by an Owner requiring DECLARANT'S
consent or approval shall not be deemed to waive or render unnecessary
DECLARANT'S consent or approval to or of any subsequent similar acts by Owner.

SECTION 7.4 COSTS OF ENFORCEMENT

In the event any legal or equitable action or proceeding shall be instituted to
enforce any provision of the VALENCIA INDUSTRIAL CENTER RESTRICTIONS, the party
prevailing in such action shall be entitled to recover from the losing party all

defeat or render invalid the lien of any mortgage, deed of trust or similar
instrument securing a loan made in good faith and for value with respect to the

however, all of the VALENCIA INDUSTRIAL CENTER RESTRICTIONS shall be binding
upon and effective against any subsequent Owner of the Site or any portion
thereof whose title is acquired by foreclosure, trustee's sale, deed in lieu of
foreclosure or otherwise pursuant to such lien rights, but such subsequent Owner
shall take title free and clear of any violations of the VALENCIA INDUSTRIAL
CENTER RESTRICTIONS occurring prior to such transfer of title.

default under this Lease, and provided that Tenant has previously and validly
exercised the First Option, Tenant shall have the option (the "Second Option')
to extend this Lease for an additional period of Three (3) Lease Years beyond
the First Option Term (the "Second Option Term"). The Second Option shall be
exercised by delivery of written notice by Tenant to Landlord given not later
than one hundred twenty (120) days prior to the last day of the Sixth Lease
Year. If written notice is not given by Tenant by the deadline set forth herein,
then this Lease shall terminate at the end of the Lease term set forth in

(i)    the term of this Lease shall be extended for the period of the Second
Option Term;

(ii)   Minimum Rent for the first Lease Year of the Second Option Term shall be
increased by three percent (3 %) of the Minimum Rent payable during the last

additions to the Premises or to the building of which the Premises are a part,
as Landlord may reasonably deem necessary, including those to be performed by
<PAGE>

Tenant, without the same constituting an eviction of Tenant in whole or in part,
and rent shall not abate as a result of such entry. Landlord shall use its
reasonable efforts in making any repairs, alterations, improvements or additions
to the Premises or the building of which the Premises are a part to keep the
disruption of Tenant's business to a minimum. Nothing herein shall impose any
duty upon Landlord to do any work or perform any other act which Tenant may be
required to perform under this Lease, and the performance thereof by Landlord
shall not constitute a waiver of Tenant's default in failing to perform it.
During the six (6) months prior to the expiration of the term of this Lease,
Landlord may place upon the Premises notice "To Let" or "For Rent." If Tenant is

portion thereof, shall be applied by Landlord for the payment of amounts due to
Landlord by Tenant, then Tenant shall, upon written demand of Landlord,
immediately remit to Landlord a sufficient amount of cash to restore the deposit
to its original amount, and Tenant's failure to do so within five (5) days after
receipt of the demand shall of itself constitute a breach of this Lease. Should
Tenant comply with all terms, covenants and conditions and promptly pay all
rents and other sums as due, the deposit shall be returned in full to Tenant
within thirty (30) days following the expiration or termination of this Lease
and after the removal of Tenant and surrender of possession of the Premises to

quality, new and fully paid for by Tenant and shall conform to the general

of Landlord. Immediately after approval of Tenant's plans and specifications by
Landlord, Tenant shall diligently complete its construction in a good and
workmanlike manner as provided in accordance with all applicable federal, state
and municipal regulations. Tenant shall do nothing to create any work stoppage,
picketing or other labor disruption. Landlord reserves the right to approve
Tenant's general contractor and subcontractors, and such approval shall not
constitute a waiver of Tenant's obligations hereunder.

SECTION 4.04.  CONSTRUCTION LIENS. Tenant shall pay when due, and indemnify,
defend and hold Landlord harmless from, all claims for labor or materials
furnished or alleged to have been furnished to Tenant for use in the Premises,
which claims are or may be secured by any construction lien against the Premises
or any interest therein. Tenant shall not permit any liens under the
construction lien law to be filed against the Premises or any interest therein
and shall immediately obtain a release from any lien so filed. Nothing in the
Lease shall be construed in any way as constituting the consent or request of
Landlord to any contractor, subcontractor, laborer, or materialman for the
performance of any labor or the famishing of any materials for any alteration,
addition, improvement or repair to the Premises or any other part of the
Complex, nor as giving Tenant any right, power or authority to contract for or
permit the rendering of services or the furnishing of materials that would give
rise to the filing of a construction lien against the Premises or the Complex.

SECTION 4.05.  REMOVAL OF IMPROVEMENTS. All items of Landlord's Work, all
heating and air-conditioning equipment and all alterations and other
improvements by Tenant shall become the property of Landlord and shall not be
removed from the Premises, unless request is made by Landlord to Tenant to
remove the same. All trade fixtures, furniture, furnishings and signs installed
in the Premises by Tenant and paid for by Tenant shall remain the property of
Tenant and may be removed upon the expiration or termination of this Lease;
provided that any of such items as are affixed to the Premises and require
severance may be removed only if Tenant repairs any damage caused by such
removal and that Tenant shall have fully performed all of the terms, conditions
and covenants to be performed by Tenant under this Lease. If Tenant fails to
remove such items from the Premises by the expiration or earlier termination of
this Lease, all such trade fixtures, furniture, furnishings and signs shall
become the property of Landlord, unless Landlord elects to require their
removal, in which case Tenant shall, at its sole cost and expense, promptly
remove the same and restore the Premises to their prior condition. The covenants
contained in this Section shall survive the expiration or termination of this
Lease.

termination of this Lease, the following insurance coverage:

(a)      Public Liability. A policy of comprehensive public liability insurance
naming Landlord, Tenant and any other party designated by Landlord as the
insured, to insure against injury to property, person or loss of life arising
out of the ownership, use, occupancy or maintenance of the Premises with limits
of public liability not less than $500,000 per person for death and/or bodily
injury including personal injury, $1,000,000 per accident and/or occurrence, and
limits of property damage liability not less than $500,000 per accident and/or
occurrence. The policy shall contain a supplemental endorsement covering
contractual liability voluntarily assumed by the insured under this Lease.

(b)      Boiler and Machinery. A policy of boiler and machinery insurance in an
amount determined by Landlord to be sufficient if any time or from time to time
such equipment is located on Premises. (No boiler of any kind shall be installed
on the Premises without the Landlord's prior written consent.)

(c)      Unusual Hazards. If Tenant commits or permits any activity or the
placing or operation of any equipment on or about the Premises creating unusual
hazards, Tenant shall promptly, upon notice or demand from Landlord, procure and
maintain in force, during such activity or operation, insurance sufficient to
cover the risks created thereby. Landlord's demand for unusual hazard insurance
shall not constitute a waiver of any right Landlord may have to demand the
removal or cessation of such activity or operation.

(d)      Other. All other insurance, if any, customarily maintained by
businesses of like type, or required by any ordinance, law, or governmental
regulation to be carried or maintained by Tenant, as may be reasonably required
by Landlord or by any ordinance, law or governmental regulation.

SECTION 8.02. INSURANCE BY LANDLORD. Landlord shall obtain before the date that
Tenant gains access to the Premises pursuant to Section 1.02, and shall maintain
through the expiration or termination of this Lease, the following insurance
coverage:

(a)      Public Liability. A policy of comprehensive public liability insurance
on the Common Areas with limits of public liability not less than $500,000 per
person for death and/or bodily injury, including personal injury, $1,000,000 per
accident and/or occurrence, and limits of property damage liability not less
than $500,000 per accident or occurrence.

(b)      Comprehensive. A comprehensive policy of coverage containing fire,
extended coverage, vandalism, malicious mischief and other endorsements deemed

including the Premises and all appurtenances thereto (excluding Tenant's
merchandise, trade fixtures, furnishings, equipment, personal property and
excluding plate glass) for the full insurable replacement value thereof, with
such deductibles as Landlord deems advisable. Tenant shall be solely responsible
for carrying personal property insurance sufficient to cover the loss or damage
to Tenant's personal property.

SECTION 8.03. INSURANCE POLICIES. Insurance required of Tenant under Section

any mortgage against the Complex. Tenant shall deliver to the other copies of
such policies or certificates evidencing the existence and amounts of such
insurance with loss payable clauses satisfactory to Landlord. No such policy
shall be cancelable or subject to reduction of coverage or modification except
after thirty (30) days prior written notice to Landlord. At least ten (10) days
prior to the expiration of Tenant's policies, Tenant shall furnish Landlord with

be done which will invalidate the insurance policies furnished by Tenant or
Landlord pursuant to Sections 8.01 and 8.02. If Tenant does or permits anything
to be done which shall increase the cost of the insurance policies furnished by
Landlord, Tenant shall pay to Landlord, as Additional Rent, the amount of any
such additional premiums. Landlord may from time to time require that the policy
limits of any or all such insurance be increased to reflect the effects of
inflation and changes in normal commercial insurance practices. If Tenant fails
to comply with the requirements of this Section or Section 8.01, Landlord may
obtain such insurance and maintain it in effect, and Tenant shall pay Landlord
the premium cost and any other costs or expenses incurred by Landlord as
Additional Rent.

SECTION 8.04. EXEMPTION OF LANDLORD FROM LIABILITY. Tenant hereby agrees that
Landlord shall not be liable for injury to Tenant's business or any loss of
income or other consequential damages or for damage to the inventory, fixtures,
furnishings, improvements or other property of Tenant, Tenant's employees,
invitees, customers, sublessees, agents, occupants, contractors, or any other
person in or about the Premises, nor shall Landlord be liable for injury to the
person of Tenant, Tenant's employees, agents, contractors, occupants, invitees,
customers, sublessees, 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, sprinkler, wires, appliances, plumbing, air-conditioning or lighting
fixtures, or from any other cause whatsoever, whether said damage or injury
results from conditions arising upon the Premises, 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 Tenant. Landlord shall not be
liable for any damages arising from any act or neglect of any other tenant of
the Complex.

SECTION 8.05  INDEMNIFICATION BY TENANT. Tenant shall indemnify, defend and hold

of the Premises, or from the conduct of Tenant's business or from any activity,

elsewhere and shall further indemnify, defend and hold harmless Landlord from

performance of any obligation on Tenant's part to be performed under the terms
of this Lease, or arising from any negligence of the Tenant, or any of Tenant's
sublessees, agents, customers, invitees, contractors, occupants, or employees,
and from and against all costs, attorneys' 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 landlord by
reason of any such claim, Tenant, upon notice from Landlord, shall defend the
same at Tenant's expense by counsel satisfactory to Landlord. Tenant, as a
material part of the consideration to Landlord, hereby assumes all risk of
damage to property or injury to persons, in, upon or about the Premises arising
<PAGE>

from any cause, and Tenant hereby waives all claims in respect thereof against
Landlord.

SECTION 8.06. INDEMNIFICATION BY LANDLORD. Landlord shall indemnify, defend and
hold harmless Tenant from and against any and all claims arising from Landlord's
use of the Common Areas, or from the conduct of Landlord's business or from any

harmless Tenant from and against any and all claims arising from any breach or
default in the performance of any obligation on Landlord's part to be performed
under the terms of this Lease, or arising from any negligence of the Landlord or
any of Landlord's sublessees, agents, customers, invitees, contractors,

or proceeding brought thereon; and in case any action or proceeding be brought
against Landlord by reason of any such claim, Landlord upon notice from Tenant,
shall defend the same at Landlord's expense by counsel satisfactory to Landlord.

SECTION 8.07. MUTUAL WAIVER OF SUBROGATION. Nothing in this Lease shall be
construed so as to authorize or permit any insurer of Landlord or Tenant to be
subrogated to any right of Landlord or Tenant against the other party arising
under this Lease. Landlord and Tenant each hereby release the other to the
extent of any perils to be insured against by either of the parties under the
terms of this Lease, whether or not such insurance has actually been secured,
and to the extent of their respective insurance coverage for any loss or damage
caused by any such casualty, even if such incidents shall be brought about by
the fault or negligence of either party or persons for whose acts or negligence
the other party is responsible. All insurance policies to be provided under this
Article VIII by either Landlord or Tenant shall contain a provision that they
are not invalidated by the foregoing waiver. Such waiver shall, however, cease
to be effective if the existence thereof precludes either Landlord or Tenant
from obtaining any such policy.

ARTICLE IX

insurable value thereof immediately preceding the casualty, (ii) the building of
which the Premises are a part is damaged by an Insured Casualty to the extent of
eighty percent (80%) or more of the insurable value thereof immediately
preceding the casualty, or (iii) the Premises are damaged by a casualty or
occurrence other than Insured Casualty, or (iv) the Premises are damaged by a

disbursement of insurance proceeds to repair or replace the same, Landlord may
terminate this Lease by giving Tenant written notice of termination within sixty
(60) days after the happening of the event causing the damage. In the event the
damage is not extensive enough to give rise to Landlord's option to terminate
this Lease or Landlord does not elect to terminate this Lease, Landlord shah
promptly repair and replace the roof, exterior walls (excluding store front),
foundation and any other improvements furnished as a part of Landlord's Work or
existing on the date that Tenant was entitled to access to the Premises pursuant

restoration (except to the extent of any rent insurance proceeds actually
received by Landlord therefor) even if the Premises are not tenantable.

ARTICLE X

CONDENNATION

SECTION 10.01. TAKING OF WHOLE. In the event (i) the whole of the Premises shall
be taken or condemned for a public or quasipublic use or purpose by a competent

utility to Tenant as immediately prior to such taking, this Lease shall
terminate upon delivery of possession to the condemning authority, and any
award, compensation or damages payable as compensation for the fee estate in the
Premises (the 'Award') shall be paid to and be the sole property of Landlord,
and Tenant hereby assigns to Landlord all of Tenant's right, title and interest
in and to any and all of the Award. Tenant shall have no claim against Landlord
by reason of such taking or termination and shall not have any claim or right to
any portion of the Award to be paid to Landlord. Tenant shall continue to pay
rent and other charges hereunder until the Lease is terminated.

SECTION 10.02. PARTIAL TAKING. In the event only a part of the Premises or
Complex is taken or condemned but the Premises or the part remaining can still
be used for the same purpose and with substantially the same utility to Tenant
as immediately prior to such taking, this Lease shall not terminate and Landlord
shall repair and restore the Premises provided the cost and expense of such
repair and restoration does not exceed the amount of the Award. If the cost of
such repair and restoration exceeds the amount of the Award, Landlord may
terminate this Lease by giving Tenant written notice of termination to Tenant
within sixty (60) days of the delivery of possession to the condemning
authority. If Landlord is obligated to repair and restore the Premises as herein
provided, there shall be no abatement or reduction in any rental because of such
taking or condemnation.

(a)      Abandonment. The abandonment of the Premises or the cessation of
business by Tenant.

(b)      Failure to Pay. The failure of Tenant to make any payment of rent or
any other payment required to be made by Tenant under this Lease, when due, and

(c)      Failure to Observe Other Covenants. The failure by Tenant to repair any
waste or to observe or perform any of the terms, covenants or conditions of this
<PAGE>

Lease to be observed or performed by Tenant where such failure shall continue
for a period of twenty (20) days after written notice thereof from Landlord to
Tenant (or without notice where (i) a violation of Section 13.01 or Section
13.17 has occurred; (ii) as a result of Tenant's failure to observe any term,
covenant or condition of this Lease, Landlord has delivered three (3) or more
notices of default under this subsection (c) within a single twelve (12)-month
period; (iii) an emergency or a hazardous condition exists or a fine, penalty,
interest or cost may otherwise be imposed or incurred). Except as otherwise
provided herein, in the event of a breach of a term, covenant or condition of
this Lease which requires more than the payment of money to cure and which
cannot because of the nature of such default be cured within said twenty (20)
days, then Tenant is deemed to be complying with said notice if, promptly upon
receipt of such notice, Tenant immediately takes steps to cure the default as
soon as reasonably possible and proceeds thereafter continuously with due
diligence to cure the default within a period of time which, under all
prevailing circumstances, shall be reasonable. Failure to send a notice shall
not be construed as a waiver of such breach or as to any subsequent breach.

(d)      Insolvency. (i) The making by Tenant of any general assignment, or
general arrangement for the benefit of creditors; (ii) the filing by or against
Tenant of a petition to have Tenant adjudged a bankrupt or a petition for

substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where possession is not restored to Tenant within sixty

substantially all of Tenant's assets located at the Premises or of Tenant's
interest in this Lease, where such seizure is not discharged within sixty (60)
days.

SECTION 11.02. LANIDLORD'S REMEDIES. If any default by Tenant shall continue
uncured following notice of default, if any, as required by this Lease, for a
period applicable to the default under the applicable provision of this Lease,
Landlord has the following remedies, in addition to all other rights and
remedies provided by law or equity, to which Landlord may resort cumulatively or
in the alternative.

(a)      Termination of Lease. Landlord may at Landlord's election terminate
this Lease by giving Tenant notice of termination. On the giving of the notice,
all further obligations of Landlord under this Lease shall terminate, Tenant
shall surrender and vacate the Premises in a broom clean condition, and Landlord
may reenter and take possession of the Premises and eject all parties in
possession or eject some and not others or eject none. Termination under this
paragraph shall not relieve Tenant from the payment of any sum then due to
Landlord or from any claim for damages previously accrued or then accruing
against Tenant. Should Tenant abandon the Premises and Landlord elect to reenter
as herein provided, or if Tenant's right to possession is terminated by Landlord
because of a breach of the Lease by Tenant, this Lease shall, at landlord's
written election, terminate and Landlord shall be entitled to recover from the
Tenant (i) unpaid rent which has been earned at the time of termination, and
(ii) as liquidated damages and not as a penalty a sum of money equal to the rent
and rental loss to be paid by Tenant to Landlord for the remainder of the term
of this Lease.

(b)      Termination of Possession. Landlord may at Landlord's election
terminate Tenant's right to possession only, without terminating the Lease,
<PAGE>

following a breach of the Lease by Tenant. Upon termination of Tenant's right to
possession without termination of the Lease, Tenant shall surrender possession
and vacate the Premises immediately and possession thereof to Landlord, and
Tenant hereby grants to Landlord the immediate right to enter into the Premises,
remove Tenant's signs and other evidences of tenancy, and take and hold
possession thereof with or without process of law, and to repossess the Premises
as Landlord's former estate and to expel or remove Tenant and any others who may
be occupying or within the Premises, without being deemed in any manner guilty
of trespass, eviction, or forcible entry or detainer, without incurring any
liability for any damage resulting therefrom, without such entry and possession
terminating the Lease or releasing Tenant from Tenant's obligation to pay the
rent and to fulfill all other of Tenant's obligations under this lease for the
full term of this Lease. Landlord shall be entitled to recover from Tenant (i)
unpaid rent which has been earned at the time of termination, and (ii) as
liquidated damages and not as a penalty a sum of money equal to the rent and
rental loss to be paid by Tenant to Landlord for the remainder of the term of
this Lease. Notwithstanding any remedial action taken hereunder by Landlord
short of termination, including reletting the Premises to a substitute Tenant,
Landlord may at any time thereafter elect to terminate this Lease for any
previous default.

(c)      Storage. , Landlord may at Landlord's election store Tenant's personal
property and trade fixtures for the account and at the cost of Tenant.

(d)      Reletting of Premises. Landlord may, but shall be under no obligation
to, relet all or any part of the Premises for such rent and upon such terms as
shall be satisfactory to Landlord (including the right to relet the Premises as
a part of a larger area, the right to change the character or use of the
Premises and the right to restrict prospective tenants to those whose business
is compatible with the nature and character of the Complex). For the purpose of
such reletting, Landlord may decorate or may make any repairs, changes,
alterations or additions in or to the Premises that may be necessary or
convenient. If the Premises are relet and a sufficient sum shall not be realized
from such reletting after paying all of the expenses of such decorations,
repairs, changes, alterations and additions, the expenses of such reletting and
the collection of the rent accruing therefrom (including, but not limited to,
attorneys' fees and brokers' commissions), to satisfy the rent and other charges
herein provided to be paid for the remainder of the term of this Lease, Tenant
shall pay to Landlord promptly any deficiency, and Tenant agrees that Landlord
may file suit to recover any sum falling due under the terms of this paragraph
from time to time.

SECTION 11.03. LANDLORD MAY PERFORM. Landlord shall have the right at any time,
after ten (10) days notice to Tenant (or without notice in case of emergency or
a hazardous condition or in case any fine, penalty, interest or cost may
otherwise be imposed or incurred), to make any payment or perform any act
required of Tenant under any provision in this Lease, and in exercising such
right, to incur necessary and incidental costs and expenses, including
reasonable attorneys' fees. Nothing herein shall obligate Landlord to make any
payment or perform any act required of the Tenant, and this exercise of the
right to so do shall not constitute a release of any obligation or a waiver of
any default. All payments made and all costs and expenses incurred in connection
with any exercise of such right shall be reimbursed to Landlord by Tenant as
Additional Rent.

ASSIGNMENT AND SUBLEITING

SECTION 12.01. ASSIGNMENT BY TENANT. Tenant shall not voluntarily or by
operation of law assign, transfer, mortgage, lease, sublet, grant license or
rights to a concessionaire or otherwise transfer or encumber all or any part of
Tenant's interest in this Lease or in the Premises, or permit the use or
occupancy of the Premises or any part thereof by anyone other than Tenant,
without Landlord's prior written consent, nor may ownership of any general
partnership interest, or of more than fifty percent (50 %) of the limited
partnership interests in Tenant (if Tenant is a partnership) or of Tenant's
corporate stock (if Tenant is a corporation) be transferred without Landlord's
prior written consent, provided, however, that the restrictions on transfer of
ownership interests in Tenant set forth herein shall not apply to transfers
resulting from death. Any attempted assignment, transfer, mortgage, use, lease,
occupancy, encumbrance or subletting without such consent shall be void and
shall constitute a default under this Lease.

SECTION 12.02. NO RELEASE OF TENANT. Notwithstanding anything to the contrary
contained in this Lease, and regardless of Landlord's consent, no such
assignment, encumbrance, subletting, transfer, lease or other permission for the
use or occupancy of all or any part of the Premises shall release Tenant of
Tenant's obligation to pay the rent and to perform all other obligations to be
performed by Tenant under this Lease, and Tenant and each respective assignor
hereby waives notice of default in the payment and performance by the tenant in
possession of the rents, covenants and conditions of this Lease. Tenant and each
such assignor further agree that Landlord may deal with the tenant in possession
without notice to, and without the consent of, Tenant or any such assignor, and
any and all extensions of time, modifications, or waivers shall be deemed to be
made with the consent of Tenant and any such assignor. The acceptance of rent by
Landlord from any other person shall not be deemed to be a waiver by Landlord of
any provision hereof. Consent to one assignment shall not be deemed consent to
any subsequent assignment.

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, (ii) acknowledging that

Any such statement may be conclusively relied upon by any prospective purchaser
or encumbrancer of the Premises.

(b)      If Landlord desires to sell or finance or refinance the Complex, or
any part thereof, Tenant shall deliver to any purchaser and/or lender designated

SECTION 13.02. LANDLORD'S LIABILITY. The term "Landlord" as used in this Lease,

a tenant's interest in a ground lease of the Premises, it being expressly
acknowledged by the parties hereto that none of the terms or conditions to be
performed or observed by Landlord under this Lease are personal to the party
originally named "Landlord" hereunder. In the event of any transfer of such
title or interest, Landlord shall be released from all liability as respects
Landlord's obligations thereafter to be performed, provided that any funds held
by Landlord at the time of such transfer, in which Tenant has an interest, shall
be delivered to the grantee.

SECTION 13.03. SEVERABILITY. The invalidity of any provision of this Lease, or
of its application to any person or circumstance as determined by a court of

provision hereof and each term, covenant, condition and provision of this Lease
shall be valid and be enforced to the fullest extent permitted by law.

SECTION 13.05. CAPTIONS. Article, section and paragraph captions are not a part

contained. No amendment, change or addition to this Lease shall be binding upon
Landlord or Tenant unless it is in writing and signed by each party.

SECTION 13.07. TENANT'S REMEDIES. If Landlord shall fail to perform any
covenant, term or condition of this Lease required to be performed by Landlord,
if any, and if as a consequence of such default, Tenant shall recover a money
judgment against Landlord, such judgment shall be satisfied only out of the
proceeds of sale received upon execution of such judgment and levied thereon
against the right, title and interest of Landlord in the Premises and out of
rents or other income from such property receivable by Landlord, or out of the
consideration received by Landlord from the sale or other disposition of all or
any part of Landlord's right, title and interest in the Premises, and Landlord
shall not be personally liable for any deficiency.

SECTION 13.08. ATTORNMENT OF TENANT. Tenant shall in the event of the sale,
assignment, or other transfer of Landlord's interest in the Premises or in this
Lease, or in the event of any proceedings brought for the foreclosure of, or in
the event of exercise of the power of sale under any mortgage made by Landlord
covering the Premises, attorn to the transferee and recognize such transferee as
Landlord under this Lease.

SECTION 13.09  DELINQUENT RENT TO BEAR INTEREST. Any rent whether Minimum,
Additional, or such other sums, if any, required to be paid by Tenant pursuant
to the terms of this Lease which are not paid when due shall bear interest at
the rate of eighteen percent (18%) per annum, or the maximum rate permitted by
law, whichever is less, from the date due until paid. The payment of such
interest shall not excuse or cure any default by Tenant under this Lease.

SECTION 13.11. WAIVERS. No waiver by Landlord of any provision of this lease
shall be deemed a waiver of any other provision hereof or of any subsequent
breach by Tenant of the same or any other provision. Landlord's consent to or
approval of any act shall not be deemed to render unnecessary the obtaining of
Landlord's consent to or approval of any subsequent act by Tenant. The
acceptance of rent hereunder by Landlord shall not constitute a waiver of any
breach by Tenant even if Landlord knows of such breach at the time of acceptance
of such rent. No payment by Tenant or receipt by Landlord of a lesser amount
than the rent then due shall be deemed to be other than on account of the
earliest rent due, nor shall any endorsement or statement on any check or any
letter accompanying any check or payment as rent be deemed an accord and
satisfaction, and Landlord shall accept such check or payment without prejudice
to Landlord's right to recover the balance of such rent or pursue any other
remedy in this Lease provided.

SECTION 13.12. RECORDING. Tenant shall not record this Lease without Landlord's
prior written consent and such recordation shall, at the option of Landlord,
constitute a non-curable default of Tenant hereunder. Either party shall, upon
request of the other, execute, acknowledge and deliver to the other a "short
form" memorandum of this Lease for recording purposes.

SECTION 13.13. HOLDING OVER. In case of holding over by the Tenant after
expiration of termination of this Lease, the Tenant will pay as liquidated
damages double rent for the entire holdover period. No holding over by the
Tenant after the term of this lease, either with or without consent and
acquiescence of the Landlord, shall thereafter constitute this Lease a lease
from month to month.
<PAGE>

SECTION 13.14. 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.

SECTION 13.15. COVENANTS AND CONDITIONS. Each provision of this Lease
performable by Tenant shall be deemed both a covenant and a condition.

SECTION 13.16. BINDING EFFECT; CHOICE OF LAW. This Lease shall bind the parties,
their heirs, personal representatives, successors and assigns. This Lease shall
be governed by and be construed and interpreted in accordance with the laws of
the State of Wisconsin.

SECTION 13.17. SUBORDINATION. This Lease shall be subject and subordinate to all
mortgages which may now or hereafter affect Landlord's interest in the Premises,
whether such mortgages cover only the Premises or by blanket mortgage cover
other premises in addition to the Premises, and to any renewals, modifications,
consolidations, replacements and extensions thereof, to the full extent of all
amounts secured by the mortgages. Tenant shall, within ten (10) days after the
giving of written notice by Landlord, execute, acknowledge and deliver to
Landlord any certificate that Landlord may request to confirm such
subordination. Tenant shall attorn to and recognize any purchaser at a
foreclosure sale under any mortgage, or any transferee who acquires Landlord's
interest in the Premises by deed in lieu of foreclosure, and the successors and
assigns of such purchasers and transferees, as its landlord for the unexpired
balance (and any extensions, if exercised) of the term of the Lease upon the
same terms and conditions set forth in this Lease.

SECTION 13.18. ATTORNEY'S FEES. If either party brings an action to enforce the
terms of or declare rights under this Lease, the prevailing party in any such
action shall be entitled to recover reasonable costs, attorneys' fees and
expenses.

SECTION 13.19. CORPORATE AUTHORITY. If Tenant is a corporation, each individual
executing this Lease on behalf of said corporation represents and warrants that
he or she is duly authorized to execute and deliver this Lease on behalf of said
corporation, in accordance with a duly adopted resolution of the Board of
Directors of said corporation, and that this Lease is binding upon said
corporation in accordance with its terms.

SECTION 13.20. MORTGAGE FINANCING. In the event Landlord desires to obtain
mortgage financing and Landlord's mortgagee or mortgagees request certain
mortgage modifications or amendments to this Lease, then Tenant, on demand,
agrees to execute such modifications or amendments as required. Notwithstanding
the foregoing, Tenant shall not be required to execute any modifications or
amendments to this Lease which shall modify the provisions of this Lease
relating to the amount of rent or other charges to be paid by Tenant, the size
of the Premises, the duration of the term of this Lease, or otherwise subject
Tenant to additional cost or expense. Tenant agrees to cooperate with Landlord's
efforts in obtaining said mortgage financing.

SECTION 13.21. EXPANSION OF COMPLEX. Tenant acknowledges and agrees that the
Complex may, from time to time, be expanded to include additional land,
buildings and improvements. The term 'Complex', as used in this Lease, refers to
