                             September 30, 1999
                                 (Unaudited)


1. Basis of presentation

The accompanying condensed consolidated financial statements of Fusion Medical
Technologies, Inc. (the "Company" or "Fusion") have been prepared in accordance
with generally accepted accounting principles for interim financial information
and with the instructions for Form 10-Q and Article 10 of Regulation S-X.  The
condensed consolidated balance sheet as of September 30, 1999, and the
condensed consolidated statements of operations for the three and nine month
periods ended September 30, 1999 and 1998, and the condensed consolidated
statements of cash flows for the nine month periods ended September 30, 1999
and 1998 are unaudited but include all adjustments (consisting of normal
recurring adjustments) which the Company considers necessary for a fair
presentation of the financial position at such dates and the consolidated
operating results and cash flows for those periods.  Although the Company
believes the disclosures in these condensed consolidated financial statements
are adequate to make the information presented not misleading, certain
information normally included in financial statements and related footnotes
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to the rules and regulations of the Securities
and Exchange Commission.  The accompanying condensed consolidated financial
statements should be read in conjunction with the financial statements as
contained in the Company's Annual Report on Form 10-K for the year ended
December 31, 1998.

Results for any interim period are not necessarily indicative of results for
any other interim period or for the entire year.

Certain previously reported balances have been reclassified to provide
consistency with current presentation.


2. Net loss per share

Basic and diluted loss per common share are computed using the weighted average
number of shares of common stock outstanding. Common equivalent shares from
stock options and warrants are excluded from the computation of diluted net
loss per common share as their effect is anti-dilutive. Stock options to
purchase 1,333,683 and 1,252,469 shares of common stock at prices ranging from
$0.16 to $11.75 per share were outstanding at September 30, 1999 and 1998,
respectively, but were not included in the computation of diluted income per
share. At September 30, 1999 and 1998, there was one warrant outstanding to
purchase 8,285 shares of common stock at an exercise price of $4.00 per share
but is excluded from the computation of diluted net loss per common share. In
addition, at September 30, 1999 and 1998, there was another warrant outstanding
to purchase 4,500 shares of common stock at an exercise price of $4.00 per
share but also is excluded from the computation of diluted net loss per common
share.


3. Cash, cash equivalents and available-for-sale securities

The Company classifies all highly liquid investments purchased with an original
maturity of three months or less as cash equivalents.  Cash and cash
equivalents include money market funds and various deposit accounts.

                                (Unaudited)

The Company classifies both short-term and long-term investments as available-
for-sale.  Such investments are recorded at fair market value and unrealized
gains and losses are recorded as a separate component of equity until
realized. Interest income is recorded using an effective interest rate, with
associated premium or discount amortized to interest income.  The cost of
securities sold is based upon the specific identification method.


4.   Inventory

As of March 31, 1999, the Company began capitalizing its inventories of raw
materials related to FloSealTM. Inventory is recorded at the lesser of cost or
market using the FIFO method.

5.   Debt

In December 1997, the Company signed an agreement for a bank loan facility to
finance previously acquired equipment up to a total of $1,000,000, and future
equipment purchases for up to a total of $2,500,000. The facility, as amended,
is secured by the equipment financed. Available credit under this facility, as
amended, expired in February 1998. The outstanding loan balance is subject to a
floating interest rate equal to the bank's prime rate plus 1.5% per annum
(9.75% at September 30, 1999). As of September 30, 1999, the Company had drawn
down $291,953 on the equipment loan facility. In connection with this loan
facility, the Company issued a warrant to purchase 4,500 shares of common stock
at an exercise price of $4.00 per share. This warrant expires in December 2002.
These facilities are subject to specific positive and negative covenants that
include restrictions on the declaration or payment of any dividend or any other
distributions on any of its capital stock.  The Company was in compliance with
those covenants at September 30, 1999.


6.      Stockholders' Equity

On April 6, 1999, the Company closed a follow-on public offering of 1.8 million
shares of its common stock that resulted in net proceeds to the Company of
approximately $8.1 million.

7.   Segment Reporting

The Company operates in one reportable segment: surgical sealants and topical
hemostat products. The Company is compliant with the segment reporting
requirements of SFAS No.131 "Disclosures about Segments of an Enterprise and
Related Information," which establishes annual and interim reporting standards
for an enterprise's business segments and related disclosures about its
products, services, geographic areas and major customers.


8.   Recent Accounting Pronouncements

In June 1998, the FASB issued Statement of Financial Accounting Standards
(SFAS) No. 133, "Accounting for Derivative Instruments and Hedging Activities",
which establishes accounting and reporting standards for derivative instruments
and hedging activities.  It requires that an entity recognize all derivatives
as either assets or liabilities in the statement of financial position and
measure those instruments at fair value. The Company, to date, has not engaged
in derivative and hedging activities.  The Company will adopt SFAS No. 133 as
required for its first quarterly filing of calendar year 2001.


9.	Subsequent Event

In October 1999, the Company entered into an agreement to lease property which
will become the Company's new headquarters.  The minimum lease commitments for
the next seven years are as follows: 2000, $794,679; 2001, $1,238,559; 2002,
$1,287,418; 2003, $1,338,231; 2004, $1,391,078; 2005, $1,446,038; and 2006,
$1,503,196.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS


This Report on Form 10-Q contains, in addition to historical information,
forward-looking statements that involve risks and uncertainties.  The Company's
actual results could differ materially from those anticipated by these forward-
looking statements as a result of certain factors, including those set forth in
"Additional Factors That Might Affect Future Results" commencing on page 13 and
those set forth under Item 1 in the Company's Annual Report filed on Form 10-K
for the Year Ended December 31, 1998.


OVERVIEW

     Since inception in October 1992, we have been primarily engaged in the
research and development of surgical sealants and topical hemostats. As of
September 30, 1999, we had an accumulated deficit of $34.8 million. We have not
achieved, nor do we expect to achieve, profitability before 2001.

     We commenced selling our first product, the RapiSeal patch, in late 1996.
After careful consideration, we reallocated our capital resources to the
development of FloSeal and in late 1997 discontinued sales of the RapiSeal
patch and disbanded our sales force.

     In 1998, we conducted a ten-center, 309-patient pivotal clinical trial to
demonstrate the safety and effectiveness of FloSeal. We received a CE mark
providing European regulatory clearance on April 20, 1999. Our premarket
approval ("PMA") application for FloSeal was accepted for filing by the U.S.
Food and Drug Administration ("FDA") and given streamlined review status on
April 27, 1999. We completed the expansion of our manufacturing facility to
meet the anticipated product supply requirements for commercial sale of
FloSeal. We spent a total of approximately $215,000 for the purchase of
production equipment and approximately $535,000 for the facilities' upgrade.

     In June 1999, we signed a multi-year distribution agreement with
Minneapolis-based Sulzer Spine-Tech. Founded in 1991,Sulzer Spine-Tech is a
business unit of Sulzer Medica AG whose total annual sales exceed $1.0 billion.
Under the agreement, Sulzer Spine-Tech becomes a worldwide distributor of
FloSeal for all spinal and cranial applications. The distribution agreement
covers most global markets with the primary exception of Japan.

     Future revenues, if any, and our results of operations may fluctuate
significantly from quarter-to-quarter and will depend upon the following, among
other factors:

     o our ability to obtain regulatory clearances for FloSeal,

     o our ability to successfully commercialize the product,

     o the speed with which the Company's future products proceed through
       clinical trials and the preparation of related regulatory
       submissions,

     o the speed with which regulatory agencies review and potentially
       clear the Company's products,

     o the rate at which the Company or its corporate partners for
       distribution establish product distribution networks and mobilize
       the available sales forces,

     o the rate at which the Company's products gain market acceptance,

<PAGE>   10


ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

     o the timing and impact of the introduction of competitive products
       for surgical sealant functions, and

     o other factors relating to the commercialization of medical products.


RESULTS OF OPERATIONS


Three and Nine Months Ended September 30, 1999 and 1998


NET SALES

     Net sales for the three and nine months ended September 30, 1999 were
$56,000 and $81,000, respectively, which represented the initial revenues
resulting from the introduction of our new product line, FloSeal, in Europe.
Due to our exit of the RapiSeal Patch business in 1997 and our current focus on
the development of FloSeal, the Company had limited revenues in the three and
nine months ended September 30, 1999 and no revenues in the same periods of
1998, respectively. We filed for European regulatory clearance and received CE
mark clearance on April 20, 1999.

COST OF GOODS SOLD AND START-UP MANUFACTURING COSTS

     Cost of goods sold and start-up manufacturing costs for the three and nine
months ended September 30, 1999 were $234,000 and $379,000, respectively, which
represented the costs associated with the introduction of our new FloSeal
product line in Europe. Our exit of the RapiSeal Patch business in 1997
resulted in the elimination of such costs during the comparable periods of
1998.

RESEARCH AND DEVELOPMENT

     Research and development expenses decreased 18% to $1.4 million in the
three months ended September 30, 1999 compared to $1.7 million in the three
months ended September 30, 1998. For the nine months ended September 30, 1999,
research and development expenses decreased 24% to $3.7 million compared to
$4.9 million for the similar 1998 period. The decrease for the three and nine
months ended September 30, 1999 is primarily attributable to completion of the
309 patient FloSeal clinical trial in December 1998. For the full fiscal year
1999, the Company believes research and development expenses are not likely to
exceed those of 1998. However, as the Company devotes more resources to the
support of new products based on the FloSeal Matrix technology, quarterly
research and development expenses should increase in the fourth quarter of
1999.

MARKETING, SELLING, GENERAL AND ADMINISTRATIVE

     Marketing, selling, general and administrative expenses increased 54% to
$730,000 in the three months ended September 30, 1999, compared to $474,000 for
the similar period in 1998. Marketing, selling, general and administrative
expenses increased 17% to $1.9 million for the nine months ended September 30,
1999 compared to $1.7 million for the similar 1998 period. The increase for the
three and nine months ended September 30, 1999, compared to the year earlier
periods, was primarily the result of increases in marketing and selling
expenses associated with commercialization of FloSeal.

<PAGE>   11


ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

INTEREST INCOME AND EXPENSE

     Interest income decreased 18% to $128,000 for the three months ended
September 30, 1999 compared to $156,000 for the three months ended September
30, 1998. For the nine months ended September 30, 1998, interest income
decreased 27% to $353,000 compared to $485,000 in the prior year.  The
decreases for the three and nine months ended September 30, 1999 were
attributable primarily to the reduction in general interest rates in the
related periods 1999 (see "Liquidity and Capital Resources").  Interest expense
decreased 33% to $6,000 for the three months ended September 30, 1999 compared
to $9,000 for the three months ended September 30, 1998. For the nine months
ended September 30, 1998, interest expense decreased 68% to $20,000 compared to
$62,000 in the prior year. The decline in interest expense for the three and
nine months ended September 30, 1999 was due to declines in interest-bearing
debt.


NET LOSS

     As a net result of the items discussed above, the net loss was $2.2
million for the three months ended September 30, 1999.  This is an increase of
nine percent or $172,000 over the net loss of $2.0 million for the similar
period in 1998. The net loss was $5.6 million for the nine months ended
September 30, 1999.  This is an improvement of 8% or $491,000 over the net loss
of $6.1 million for the similar period in 1998.


LIQUIDITY AND CAPITAL RESOURCES

     At September 30, 1999, our cash, cash equivalents and available-for-sale
securities were $9.2 million compared to $7.2 million at December 31, 1998.
Since our inception, we have funded the business with proceeds from private
security placements, our initial public offering of common stock and, most
recently, with a follow-on public offering of 1.8 million shares of our common
stock on April 6, 1999.

     For the nine months ended September 30, 1999 and 1998, our operations
consumed cash of $5.7 million and $5.8 million, respectively.  The decrease in
cash consumed by operations was due primarily to a decrease in net loss of
$491,000 resulting from reductions in clinical trial spending and in research
and development spending.  In addition, during 1999, we recorded a $311,000
increase in inventory and a $453,000 reduction in accrued expenses which were
partially offset by a $358,000 increase in accounts payable. We expect the use
of cash in operating activities to increase through calendar year 1999 and into
2000 as we continue to devote resources to the commercialization of FloSeal
and develop other products based on the FloSeal technology.

     For the nine months ended September 30, 1999, investing activities
provided net cash of $447,000 and net cash of $3.8 million for the similar
period in 1998. Year-to-date in 1999, sales and maturities of available-for-
sale securities provided $5.5 million of cash which was partially offset by the
acquisition of property and equipment of $565,000 and purchases of available-
for-sale securities of $4.5 million. For the nine months ended September 30,
1998, sales and maturities of available-for-sale securities provided $6.0
million of cash which was partially offset by the acquisition of property and
equipment of $147,000 and purchases of available-for-sale securities of $2.0
million.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

     For the nine months ended September 30, 1999 and 1998, financing
activities provided net cash of $8.2 million and $414,000, respectively. The
net cash provided by financing activities for the nine months ended September
30, 1999 was due primarily to net proceeds from the issuance of common stock
and exercises of stock options which totaled $8.3 million. The net cash
provided by financing activities for the nine months ended September 30, 1998
was due primarily to net proceeds from the issuance of notes payable which
totaled $408,000.

     In December 1997, the Company signed an agreement for a bank loan facility
to finance previously acquired equipment up to a total of $1,000,000, and
future equipment purchases for up to a total of $2,500,000. The facility, as
amended, is secured by the equipment financed. Available credit under this
facility, as amended, expired in February 1998. The outstanding loan balance is
subject to a floating interest rate equal to the bank's prime rate plus 1.5%
per annum (9.75% at September 30, 1999). As of September 30, 1999, the Company
had drawn down $291,953 on the equipment loan facility. In connection with this
loan facility, the Company issued a warrant to purchase 4,500 shares of common
stock at an exercise price of $4.00 per share. This warrant expires in December
2002. These facilities are subject to specific positive and negative covenants
that include restrictions on the declaration or payment of any dividend or any
other distributions on any of its capital stock.  The Company was in compliance
with those covenants at September 30, 1999.

     We closed a follow-on public offering of 1.8 million shares of our common
stock on April 6, 1999. The follow-on offering resulted in net proceeds to us
of approximately $8.1 million. We believe our existing cash, cash equivalents
and available-for-sale securities will be sufficient to fund our operations
into the third quarter of the year 2000. However, the amount and timing of our
capital requirements cannot be predicted with certainty. Our future capital
requirements will depend on numerous factors, including the following:

     o timing of regulatory actions on FloSeal,

     o our ability to enter into additional distribution agreements,

     o the timing of our manufacturing scale-up,

     o the extent and timing of any future FloSeal sales, and

     o the nature, timing and success of other products under development.

     We expect to commit substantial capital resources to the development of
commercial-scale manufacturing for FloSeal. The working capital requirements
for the development and commercial launch of our other products are also
expected to be substantial. If we are unable to secure corporate partners to
distribute our products, we will incur substantial additional expenditures in
sales and marketing capability. Given these factors, we anticipate that we will
need additional financing before the end of the second quarter of the year
2000.

     On November 2, 1999, we announced we had entered into agreements to
provide for the private sale of a total of 872,000 shares of newly issued
common stock to selected institutional and other accredited investors.  The
purchase price per share under these agreements was $9.50.  The closing of this
financing is expected to occur concurrently with the declaration of
effectiveness by the Securities and Exchange Commission of a resale
registration statement relating to the shares.

         RESULTS OF OPERATIONS (CONTINUED)

ADDITIONAL FACTORS THAT MIGHT AFFECT FUTURE RESULTS

This Report on Form 10-Q contains, in addition to historical information,
forward-looking statements that involve risks and uncertainties.  The Company's
actual results could differ materially from those anticipated by these forward-
looking statements as a result of certain factors, including those set forth
under Item 1 in the Company's Annual Report filed on Form 10-K for the Year
Ended December 31, 1998.


We did not generate any revenues in 1998 and only modest revenues in 1999.  We
have a history of losses and we expect losses to continue in the future.

     We did not generate any revenues in 1998 and have generated only limited
revenues so far in 1999.  We have a history of losses and we expect losses to
continue in the future.  We have not achieved, nor do we expect to achieve,
profitability before 2001. We incurred net losses of $7.0 million, $9.9 million
and $7.7 million for the years ended December 31, 1996, 1997 and 1998,
respectively.  As of September 30, 1999, we had an accumulated deficit of $34.9
million. We have reported revenues of $81,000 in European sales for the second
and third quarters of 1999.  We have not had significant revenues in any period
since our inception. We expect to increase our operating expenses in the near
future, including sales and marketing, manufacturing and research and
development expenses, as we approach U.S. commercialization of FloSeal and
continue development of our other products.  As a result, we will need to
generate significant revenues to achieve and maintain profitability.  The
amount of future net losses and the time required to achieve profitability are
highly uncertain.  If we do achieve profitability in any period, we cannot be
certain we will sustain or increase such profitability on a quarterly or
annual basis.

If we do not obtain FDA approval, we cannot sell FloSeal in the United States,
which would significantly harm our business.

     FloSeal is considered to be a medical device and is regulated by the
Center for Devices and Radiological Health, a division of the FDA, and, as such
will be subject to extensive regulation in the United States.  Before we can
market FloSeal or any of our other products under development in the United
States, we must show in clinical trials our products are safe and effective,
and obtain approval from the FDA, which cannot be guaranteed.

     We must obtain a PMA from the FDA for FloSeal before we can market it.  In
1998, we conducted a ten-center, 309-patient pivotal clinical trial to
demonstrate the safety and effectiveness of FloSeal.  Our PMA application for
FloSeal was accepted for filing by the FDA and given streamlined review status
on April 19, 1999.  We cannot guarantee either the timing or receipt of
approval.  The FDA may also limit the commercial claims and uses of FloSeal or
any of our other products.  Delays in the FloSeal approval process, limitation
of labeling claims or denial of our PMA would cause our business to be
materially and adversely affected.  We will face a similar process and similar
risks for any new product we wish to market.

If we do not successfully commercialize FloSeal, our business will suffer.

     We are dependent upon the success of our lead product under development,
FloSeal.  We have not yet received necessary regulatory approval for the
commercial sale of FloSeal in the United States.  We received the European CE
mark on April 20, 1999 and, as required by statute, have notified the FDA that
we have begun to export FloSeal to Europe.  Our PMA application for FloSeal was
accepted for filing by the FDA and given streamlined review status on April 19,
1999.  Our success after regulatory approval, if any, will depend on the
medical community's acceptance of FloSeal and our ability to successfully scale
up commercial manufacturing and develop an effective sales, marketing and
distribution capability.  We cannot predict how quickly, if at all, the medical
community will accept FloSeal, or if accepted, the extent of its use.  A
surgeon's use of FloSeal will require the surgeon to change from his or her
usage of more familiar currently available products.  For FloSeal to achieve
market acceptance, it will have to be priced competitively and offer clinically
significant advantages over other commercially available products.  Even if the
market generally accepts FloSeal, surgeons may

         RESULTS OF OPERATIONS (CONTINUED)

choose to use it in fewer procedures than projected.  If FloSeal does not
achieve significant market adoption, our business will be materially and
adversely affected.
Significant increases in operating expenses in the future may adversely affect
our operating results and financial condition.

     We plan to significantly increase our operating expenses to expand our
sales and marketing operations and broaden our customer support capabilities as
we approach commercial introduction of FloSeal and fund greater levels of
product development.  Our operating expenses, which include sales and
marketing, research and development and general and administrative expenses,
are based on our expectations of future revenues and are relatively fixed in
the short term.  If revenues fall below our expectations, we will not be able
to quickly reduce our spending in response, which would materially adversely
affect our operating results and financial condition.

Our limited operating history, dependence upon an unapproved product and lack
of experience in manufacturing and marketing FloSeal may result in significant
fluctuations of our financial results.

     Our limited operating history, dependence upon FloSeal to provide future
revenue and our lack of experience in manufacturing and marketing FloSeal may
likely cause our operating results to fluctuate dramatically.  As a result of
these fluctuations and uncertainties in our operating results, we believe
quarter-to-quarter or annual comparisons of our operating results are not a
good indication of our future performance.  In addition at some point in the
future, these fluctuations may likely cause us to perform below the
expectations of public market analysts and investors.  If our results were to
fall below market expectations, the price of our common stock would likely
fall.  Our limited operating results have varied widely in the past, and we
expect they will continue to vary significantly from quarter-to-quarter as we
attempt to commercially produce and establish our products in the market after
the appropriate governmental approvals are received.

We may need to raise additional money before we expect to achieve
profitability.  If we fail to raise any such needed additional money, our
business will suffer.

     Our current cash, cash equivalents and available-for-sale securities plus
 the net proceeds, if any, from the private sale of common stock announced on
November 2, 1999, should be sufficient to fund our planned operations through
the 2001.  If the private sale of common stock can not be concluded or if we
fail to achieve profitability by 2002, we would need to raise additional funds
in order to be successful.  Future financing strategies may include, but are
not limited to:

     o partnering relationships with larger medical device companies,

     o bank facilities, or

     o debt or additional equity offerings.

     If we are unable to raise additional funds when needed, we may not be able
to market FloSeal as planned, or continue development of our other products,
which would materially and adversely affect our business.

Additional funding may not be available to us or, if available, may not be
available on commercially reasonable terms.

     If we need to raise additional money to fund our operations, we cannot be
certain that funding from any source will be available to us on acceptable
terms, or at all.  The amount and the timing of raising additional funds will
depend primarily upon our ability to obtain needed regulatory clearances and

                                    14

         RESULTS OF OPERATIONS (CONTINUED)

generate revenues from the sale of FloSeal.  Our inability to obtain any needed
additional funding on reasonable terms will materially and adversely affect our
business.

We may have to incur significant costs in attaining and maintaining compliance
with regulations governing our manufacturing operations.

     We are required to demonstrate compliance with the good manufacturing
practice requirements for medical devices incorporated into the FDA's Quality
System Regulations ("QSR") before approval of FloSeal, and maintain compliance
after approval.  The  QSR are similar to good manufacturing practices and
relate to product testing and quality assurance, as well as the maintenance of
records and documentation.  The FDA enforces the QSR through pre-approval and
periodic post-approval inspections. We can provide no assurance we will be able
to maintain compliance on an ongoing basis.  If we or any third party
manufacturer of our products does not conform to the QSR and cannot be brought
up to such a standard, we will be required to find alternative manufacturers
that do conform.  This may be a long and difficult process.  Those
manufacturers must be approved by the FDA before they can commercially
manufacture our products.  We may have to incur significant costs to comply
with such laws and regulations and our failure to comply with them could lead
to penalties that could have a material and adverse affect on our business.

International sales of our products will also be subject to extensive
regulation.

     Marketing of FloSeal in jurisdictions outside of the U.S. requires
compliance with additional local regulations. We cannot guarantee we will be
able to comply with such local regulations and thus cannot guarantee that we
will be allowed to sell FloSeal to any or all of these markets.

If we fail to maintain regulatory approvals after FloSeal is commercialized,
our business will suffer.

     After regulatory approval of FloSeal, we will continue to be subject to
extensive regulatory requirements.  These regulations are wide-ranging and
govern, among other things:

     o product changes or modifications,

     o product manufacturing,

     o Quality System requirements,

     o Medical Device Reporting regulations,

     o FDA's restrictions on promoting products for unapproved, off-label
       uses,  and

     o product sales and distribution.

     If we fail to comply or maintain compliance with medical device laws or
regulations, we may be fined and barred from selling our products.  If the FDA
believes that we are not in compliance with the law, it can:

     o detain or seize our products,

     o issue a recall,

     o enjoin future violations, and

     o assess civil and criminal penalties against us.

                                    15

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

     Our failure to comply with regulatory requirements could have a material
adverse effect on our business.  Regulations are also subject to change.  We
cannot predict the effect, if any, that such changes might have on our
business.

Our ability to achieve any significant revenue will depend on our ability to
establish effective sales, marketing and distribution capabilities.

     If we fail to establish a sufficient marketing and distribution or direct
sales force to commercialize FloSeal or any of our other products, our ability
to enter new or existing markets will be impaired.  Our inability to
effectively enter these markets would materially and adversely affect our
business.  The alternatives for selling our products are:

     o distribution agreements,

     o collaborative arrangements with corporate strategic partners, or

     o our own direct sales force.

     Although we entered into a multiyear distribution agreement with Sulzer
Spine-Tech, Inc. in June 1999, we cannot be certain we will be able to enter
into additional distribution agreements or collaborative arrangements on a
timely basis or at all, or that these relationships will be successful.  We
have only limited experience in establishing and managing a direct sales force,
from selling the RapiSeal patch, a discontinued product line, and we cannot be
certain we can establish and manage a direct sales force for FloSeal.  Our
ability to achieve any significant revenue will depend heavily upon our success
in establishing effective sales and market capabilities, through a combination
of distribution or collaboration arrangements and a direct sales force.

We may be unable to effectively commercialize FloSeal because the market for
surgical bleeding control products is highly competitive.

     The market for products that control surgical bleeding is highly
competitive. A wide variety of approved products such as Gelfoam plus thrombin
and fibrin glues, exist today and will compete directly with FloSeal, which has
not yet received approval for U.S. sale. Many competitive products are produced
by companies that have competitive advantages over us, such as:

     o greater name recognition,

     o broader product lines,

     o greater distribution capabilities,

     o substantially greater capital resources, and

     o larger marketing, research and development staffs and facilities.

     Such companies include, for example Pharmacia & Upjohn AB and Johnson &
Johnson.  We cannot be certain FloSeal or our other products will be able to
successfully compete against these products and companies, or any other
companies which may enter the marketplace.  In addition, we cannot be certain
that current competitors or other companies will not succeed in developing
technologies and other products that are more effective or that would render
our technology or products obsolete or unable to compete.

We have one issued patent and five pending patent applications.  Our failure to
obtain additional issued patents and, consequently, to protect our proprietary
technology, could impair our competitive position.

                                    16

<PAGE>   17


ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

     We regard elements of FloSeal as proprietary and we attempt to protect
them through patent and trade secret laws and restrictions, as well as licenses
and contractual confidentiality provisions.  Any steps we take to protect our
intellectual property may be inadequate and expensive.  Despite our efforts, we
may be unable to prevent third parties from infringing upon or misappropriating
our intellectual property.  We have one issued U.S. patent and five pending
U.S. patent applications relating to FloSeal and other products under
development. We also have two corresponding international patent applications
filed under the Patent Cooperation Treaty and may file additional patent
applications outside the United States at a later date.  Obtaining foreign
patents may be more difficult than obtaining U.S. patents because of
differences in patent laws.  Protection provided by foreign patents, if
obtained, and any other foreign intellectual property protection may be weaker
than provided domestically.  Any existing or new patent applications, domestic
or international, may not result in:

     o the priority of our patent applications over others' applications or
       issued patents,

     o the issuance of any patents, or

     o any competitive advantage.

     Furthermore, our competitors may independently develop similar technology
in the future that substantially limits the value of our intellectual property.

We may not be able to commercialize FloSeal or our other products under
development if they infringe existing patents or patents that have not yet
issued, which would materially harm our business.

     We have conducted searches to determine whether our patent applications
interfere with existing patents.  Based upon these searches, we believe that
our patent applications and products do not interfere with existing patents.
However, we cannot be sure that relevant patents have not been issued that
could block our ability to obtain patents or commercialize our products.
Moreover, since U.S.  patent applications are not a matter of public record, a
patent application could currently be on file that would stand in our way of
obtaining an issued patent.  In addition, a number of medical device and other
companies, universities and research institutions have filed patent
applications or have issued patents relating to compositions and methods for
surgical sealing.  The issuance of any of these potentially competing patents
could materially and adversely affect our business.

The European fear of "mad cow disease" could adversely impact acceptance of our
products in Europe.

     There is uncertainty as to the European acceptance of products that
incorporate elements derived from cows.  This uncertainty is due to concerns
over transmission of disease from cows to humans.  This disease in cows is
commonly referred to as "mad cow disease." Transmission of this disease to
humans may cause serious illness or death.  FloSeal and our other products
under development contain thrombin and gelatin derived from bovine tissue only
from traceable U.S. herds.  There have been no cases of mad cow disease
associated with cattle from traceable U.S. herds.  Despite this fact, concerns
over transmission of this disease to humans may prevent or substantially delay
the acceptance of FloSeal in Europe.  A delay could materially and adversely
affect our business.

We cannot be certain that we will be able to manufacture FloSeal in high
volumes at commercially reasonable costs.

     We have produced FloSeal for use in Europe and our clinical trials.
However, we have no experience manufacturing FloSeal or any of our other
products under development in the amounts necessary to achieve significant
commercial sales. We have expanded our manufacturing capacity, but we

                                    17

<PAGE>   18


ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

cannot be certain we will be capable of reliable, high-volume manufacturing at
commercially reasonable costs.  We could encounter problems related to:

     o capacity constraints,

     o production yields,

     o quality control, and

     o shortages of qualified personnel.

     Such problems could affect our ability to adequately scale-up production
of our products and fulfill customer orders on a timely basis, which could
materially and adversely affect our business.

     Our manufacturing facilities will be subject to QSR, international quality
standards and other regulatory requirements, including preapproval inspection
for FloSeal and periodic post-approval inspections for all products. Our
failure to implement and maintain our facilities in accordance with these
regulatory requirements and standards will result in a delay or termination of
production.  Any delay or termination of production would materially and
adversely affect our business.

We do not have long-term supply arrangements with our key suppliers.  There is
a risk we could lose one or more of our key suppliers, which would disrupt our
business.

     We currently purchase bovine hides and thrombin, essential elements of
FloSeal, as well as sterilization services for the end product, from single
suppliers.  We purchase bovine hides from Spear Products and thrombin from
GenTrac, Inc.  We do not have long-term supply arrangements with any of these
suppliers.  In the event any of our current single source suppliers become
unavailable for any reason, we will be required to obtain regulatory approval
of alternative suppliers and our business would be disrupted. Any disruption
caused by a loss of one of these suppliers could materially and adversely
affect our business.

Failure of our end-users to obtain adequate third party reimbursement for the
procedures utilizing FloSeal or our other products could adversely affect our
business.

     In the United States, health care providers that purchase medical devices,
such as FloSeal and our other products under development, generally rely on
third party payors, such as federal Medicare, state Medicaid and private health
insurance plans, to reimburse some or all of the cost of the procedure in which
the medical device was used. We expect in a prospective payment system, such as
the one utilized by the Health Care Financing Administration which manages the
federal Medicare program, and whose polices are followed by state Medicaid and
private third party payors, our products' costs will be incorporated into the
overall cost of the procedures, and there will not be separate reimbursement
for our products. Our success depends, in part, upon health care providers
obtaining satisfactory reimbursement from third party payors for surgical
procedures that may use FloSeal and our other products under development.
Failure by our products' users to obtain sufficient reimbursement from third
party payors for procedures in which our products are used or adverse changes
in governmental and private third party payors' policies toward reimbursement
for such procedures could mean that they reduce or eliminate purchases of our
products, which would materially and adversely affect our business.

     If we obtain the necessary foreign regulatory approvals, international
market acceptance of our products would be dependent, in part, upon the
availability of reimbursement for our products or procedures that use our
products by the prevailing health care payment systems. Reimbursement and
health care payment systems in international markets vary significantly by
country and include both government-sponsored health care and private
insurance. We intend to seek international reimbursement

                                    18

<PAGE>   19


ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS (CONTINUED)

approvals where applicable. We cannot be certain any such approvals will be
obtained in a timely manner, if at all. Failure to receive international
reimbursement approvals could materially and adversely affect our business.

We may face product liability claims related to the use or misuse of our
products.

     We face an inherent business risk of product liability claims in the event
the use or misuse of our products results in personal injury or death. We have
not experienced any such claims to date, but we cannot be certain, in
particular after commercial introduction of our products, that we will not
experience losses due to product liability claims. We currently maintain
liability insurance with combined coverage limits of $3.0 million on a claims-
made basis. We cannot be certain that the insurance policies' coverage limits
are adequate. The insurance is expensive, difficult to obtain and may not be
available in the future on acceptable terms, or at all. Any claims against us,
regardless of their merit, could materially and adversely affect our business.

The Year 2000 Computer Problem

     We may be adversely affected by the Year 2000 computer problem.  Beginning
on January 1, 2000, computer systems and software will produce erroneous
results or fail unless they have been modified or upgraded to process date
information correctly.  Our primary exposure with respect to this problem
involves third party software we have purchased or licensed for our financial
systems, network and telecommunications equipment.  Our financial systems
software is Year 2000 compliant.  We have implemented the software needed to
make our network Year 2000 compliant.  We have analyzed the Year 2000 risk with
regard to our telecommunications equipment and have concluded that there is no
material Year 2000 risk.

     We have surveyed all our major vendors and have found their preparedness
to be sufficient.  We have expended approximately $25,000 in our internal
review and will continue to make certain investments, estimated not to exceed
$50,000, in our software systems and applications to ensure our information
systems are ready for the year 2000.  The necessary funds to support these
renovations have come from our operating budget and we do not anticipate that
we will need to allocate special future funding outside of historical levels
for this item.  The financial impact of our year 2000 readiness effort has not
been and is not anticipated to be material to our financial position or results
of operations in any given year.  To date, we have not encountered any material
Year 2000 problems with software and information systems provided to us by
third parties.  We have contacted our suppliers of bovine hides and thrombin,
the two essential materials we require for FloSeal and have confirmed that
there is no material Year 2000-associated risk of a delay in supply from these
sources.  We could be materially adversely affected if third parties, upon whom
we depend in order to run our day-to-day business, experience Year 2000
problems.  A worst case scenario would involve a complete disruption in the
delivery of materials,

power, heat and water to our facilities, which would prevent us from being able
to manufacture and ship our products.  We have not developed contingency plans
for operation of our business in the event of a complete disruption of
utilities and other services nor do we believe it is feasible to do so.  Other
than problems that would be experienced by businesses generally, we do not
anticipate any Year 2000 problems unique to our company.

        (2)     Trash disposal, property management (with a property management
fee equal to 4% of Base Rent under this Lease) and fire safety monitoring
services and the cost of any environmental or fire safety system inspections;

        (3)     Any deductible portion of an insured loss concerning the
Building or the Exterior Areas to the extent the deductible maintained does not
exceed a commercially reasonable amount given the nature of the property and
the insurance then available in the market (provided that with respect to any
loss occurring while the insurance for Lessor is provided by any insurance
program maintained by The Prudential Insurance Company of America for its own
property and for properties to which it provides management or other services,
the deductible actually maintained under such insurance program shall be deemed
commercially reasonable for purposes of this Paragraph 4.2);


        (4)     The cost of the premiums for the liability and property
insurance policies maintained by Lessor

                                       3
<PAGE>   36


under paragraph 8 hereof; provided that if Lessor elects to self-insure or
includes the Premises under blanket insurance policies covering multiple
properties, then the cost included in Operating Expenses shall include the
portion of the reasonable cost of such self-insurance or blanket insurance that
is reasonably allocated to the Premises;

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

        (6)     The cost of water, gas, electricity and telephone to service
the Exterior Areas;

        (7)     the cost of Lessor's performing the maintenance obligations
described in paragraph 7.1, including replacements;

        (8)     Except as otherwise set forth in paragraph 7.1, the cost of
operating, repairing, replacing and maintaining the Building, the roof
membrane, and any other utilities or equipment, wherever situated;

        (9)     the cost of a Commercial General Liability policy of insurance,
insuring Lessor, but not Lessee, against liability arising out of the
ownership, use, occupancy or maintenance of the Premises, in amounts determined
by Lessor, if Lessor determines to obtain such insurance; and

        (10)     any charges or fees applicable to the Premises imposed or
assessed by any master association or pursuant to any covenants, conditions and
restrictions and/or reciprocal easement agreement affecting the Premises and
other property in the project of which the Premises is a part.

        (2)     The inclusion of the improvements, facilities and services set
forth in paragraph 4.2(a) of the definition of Operating Expenses shall not be
deemed to impose an obligation upon Lessor to either have said improvements or
facilities or to provide those services unless the Premises already has the
same, Lessor already provides the services, or Lessor has agreed elsewhere in
this Lease to provide the same or some of them.

        (3)     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

                                       4
<PAGE>   37


estimated by Lessor from time to time of annual Operating Expenses and the same
shall be payable monthly or quarterly, as Lessor shall designate, during each
twelve-month period of the Lease term, on the same day as the Base Rent is due
hereunder.  In the event that Lessee pays Lessor's estimate of Operating
Expenses as aforesaid, Lessor shall deliver to Lessee within sixty (60) days
after the expiration of each calendar year, or as soon thereafter as
practicable, a reasonably detailed statement showing the actual Operating
Expenses incurred during the preceding year.  If Lessee's payments under this
paragraph 4.2(c) during said preceding year exceed the actual amount indicated
on said statement, Lessee shall be entitled to credit the amount of such
overpayment against Operating Expenses next falling due.  If Lessee's payments
under this paragraph during said preceding year were less than the actual
amount as indicated on said statement, Lessee shall pay to Lessor the amount of
the deficiency within ten (10) days after delivery by Lessor to Lessee of said
statement.

        (4)     Lessor and Lessee shall promptly adjust between them by
appropriate cash payment any balance determined to exist with respect to
Operating Expenses after the end of the calendar year in which this Lease
terminates, prorating for any partial year involved.

        (5)     Limitation on First Year Operating Expenses.  Lessor hereby
                -------------------------------------------
agrees that the amount payable by Lessee for Operating Expenses attributable to
the first twelve (12) months of the term of this Lease shall not exceed the sum
of (a) $191,400.00, and (b) any increases in real property tax attributable to
the value of tenant improvements installed in the Premises in excess of a value
equal to $725,000.00.


        (6)     Operating Expense Exclusions.

to the contrary, Operating Expenses shall not include the following:

        (1)     Any ground lease rental;

        (2)     Costs incurred by Landlord for the repair of damage to the
extent Landlord is reimbursed by insurance proceeds;

                                       5
<PAGE>   15


        (4)     Marketing costs including leasing commissions, attorneys' fees,
space planning costs, and other costs and expenses incurred in connection with
leases, sublease and/or assignment negotiations and transactions with present
or prospective lessees or other occupants of the Building;
        (1)

        (5)     Depreciation or reserves;

        (6)     Costs incurred by Lessor due to the violation by Lessor of the
terms and conditions of any lease of space in the Building;

        (7)     Overhead and profit increments paid to Lessee or to its agents
or affiliates for goods and/or services to the extent the same exceeds the
costs of such goods and/or services that could be obtained from unaffiliated
third parties on a competitive basis;

        (8)     Lessor's corporate overhead and general and administrative
expense;

        (9)     Tax penalties incurred as a result of Lessor's negligence,
inability or unwillingness to make payments and/or file any income tax or
informational returns when due;

        (10)     Costs arising from remedial work or the presence of Hazardous
Materials (as defined in Paragraph 47) in or about the Building or the site on
which is resides (the "Site"), including, without limitation, Hazardous
Materials in the ground water or soil, but only to the extent the same are
Preexisting Conditions (as defined in Paragraph 47.3);

        (11)     Costs arising from Lessor's charitable or political
contributions;

        (12)     Costs (including in connection therewith all attorneys' fees
and costs of settlement judgments and payments in lieu thereof) arising from
claims, disputes or potential disputes in connection with potential or actual
claims litigation or arbitrations pertaining to the Lessor and/or the Building
and/or Site;

                                       6
<PAGE>   38


        (13)     Costs of the initial construction of the Building and Common
Area.


        (7)     Audit Right.  In the event of any dispute as to the amount
                -----------
of Operating Expenses as set forth in Lessor's statement of Operating Expenses
delivered to Lessee, Lessee shall have the right, after reasonable notice and
at reasonable times within one year after the final statement for such
Operating Expenses is delivered to Lessee, to inspect and photocopy (at
Lessee's expense) Lessor's accounting records with respect to 100% ("Lessee's
Share") of Operating Expenses.  If, after such inspection and photocopying,
Lessee still disputes the amount of Operating Expenses as set forth in Lessor's
statement, Lessee shall be entitled to retain an independent certified public
accountant reasonably approved by Lessor to audit Lessor's records to determine
the proper amount of such Operating Expenses and the proper amount payable by
Lessee pursuant to this Lease.  Lessee agrees to pay the cost of such audit,
provided that Lessor shall pay such cost if the audit reveals that Lessor's
determination of Operating Expenses as set forth in Lessor's statement
overstated Operating Expenses by 5% or more.  Lessor shall be required to
maintain records of all Operating Expenses for one year after the final
statement for such Operating Expenses.  If such audit reveals an overstatement
or understatement of Operating Expenses, the amount of the differential shall
be promptly reimbursed to Lessee by Lessor or paid by Lessee to Lessor, as the
case may be.

        (8)     Special Limitation on Operating Expenses.
                ----------------------------------------
Anything to the contrary herein notwithstanding, Lessor, at Lessor's cost,
shall be responsible for the maintenance of the roof structure (excluding the
roof membrane) and structural elements of interior load bearing walls, exterior
walls and foundations of the Building (the "Lessor Structural Elements").


       4.3     Certain Capital Items.  As used herein, the term "Capital
               ---------------------
Item" means an item, the cost of which under generally accepted accounting
principles, consistently applied, must be capitalized and not expensed.  As
used herein, the term "Amortized Capital Cost" means a repair, maintenance,
replacement, alteration or improvement which (a) is a Capital Item,  and (b)
either (i) costs $5,000.00 or more with respect to a single Capital Item or
(ii) has a cost that when added to other Capital Items which are not Amortized
Capital Costs would cause the amount of costs for Capital Items that are not
Amortized Capital Costs and that are paid by

                                       7
<PAGE>   39


Lessee as Operating Expenses to exceed $50,000.00 in any calendar year.  As
used herein, the term "Useful Life" means the useful life of the particular
Capital Item determined under generally accepted industry standards.  As to
each Operating Expense otherwise payable by Lessee pursuant to this Lease that
is an Amortized Capital Cost, the Amortized Capital Cost shall be included in
Operating Expenses in a monthly amount (the "Monthly Recovery Amount") which
equals the monthly amount that would fully amortize a loan having a principal
balance equal to the Amortized Capital Cost and an interest rate equal to the
Amortization Interest Rate (as defined below) in equal monthly payments over
the number of months in the Useful Life of the applicable Capital Item.
Commencing on the first day of the calendar month after the calendar month in
which the applicable Capital Item is completed and on the first day of each
month thereafter until the earlier of (A) the expiration of the term of the
Lease, or (B) the expiration of the number of months in the item's Useful Life
used to calculate the Monthly Recovery Amount, Lessee shall pay Lessor as part
of Operating Expenses an amount equal to the Monthly Recovery Amount as to each
Amortized Capital Cost.  As used herein, the term "Amortization Interest Rate"
means an interest rate equal to the LIBOR Rate plus 325 basis points, where the
"LIBOR Rate" means, for each month, the one (1) month LIBOR (London Interbank
Offered Rate) Rate published in The Wall Street Journal (the "Reported Rate")
on the first Publication Date (as defined below) of the applicable month.  If
The Wall Street Journal (i) publishes more than one (1) Reported Rate on any
Publication Date, the average of such rates shall apply or (ii) publishes a
retraction or correction of any Reported Rate, the corrected rate reported in
such retraction or correction shall apply.  If the Reported Rate is no longer
published at least monthly, the LIBOR Rate shall be deemed to be such other
London Interbank Offered Rate published in The Wall Street Journal as most
reasonably approximates the Reported Rate.  As used herein, the term
"Publication Date" means any date on which the LIBOR Rate is published in The
Wall Street Journal.

       4.4     Capital Items Incurred by Lessee for Compliance Work.
               ----------------------------------------------------
With respect to any Capital Item which is the obligation of Lessee pursuant to
paragraph 6.2(b) of the Lease and which is required for reasons other than
Lessee's particular use of the Premises, Lessee's breach of the Lease or any
alterations or other improvements to the Premises by Lessee (each, a "Lessee
Capital Cost"), Lessee may give notice to Lessor of the amount of the Lessee
Capital Cost and Lessee's opinion as to the Useful Life of the Capital Item and
that Lessee requires that Lessor reimburse Lessee for the entire cost of the
Lessee Capital Cost and agrees to repay Lessor on a monthly basis in the same

                                       8
<PAGE>   40


manner as if the Lessee Capital Cost were an Amortized Capital Cost under
paragraph 4.3.  If Lessee makes the election under this paragraph 4.4, Lessor
shall reimburse Lessee for the entire cost of such Capital Item within thirty
(30) days after Lessee's notice.  As a condition to Lessor's obligation to make
the payments to Lessee  described in paragraph 4.4, Lessee shall provide Lessor
with reasonable evidence that the costs of such Capital Item was paid and
unconditional mechanic's lien releases in the form required under California
law from the contractor and subcontractors who installed the Capital Item.

       4.5     Effect of Exercise of Option to Extend on Payment of Certain
               ------------------------------------------------------------
Amounts Under Sections 4.3 and 4.4.  In the event that Lessee exercises a
- ----------------------------------
Lease Option pursuant to paragraph 39, then with respect to Amortized Capital
Costs under paragraph 4.3 and Lessee Capital Costs under paragraph 4.4, to
which it has not made a Monthly Recovery Amount payment for the number of
months in the Useful Life of the applicable Capital Item, Lessee shall pay
during the applicable Lease Option a Monthly Recovery Amount until it has made
monthly payments for the number of months in the Useful Life of the applicable
Capital Item, taking into account all prior Monthly Recovery Amount payments.

     5.     Security Deposit.  Lessee shall deposit with Lessor upon
            ----------------
execution hereof $146,812.50 as security for Lessee's faithful performance of
Lessee's obligations hereunder.  If Lessee fails to pay rent or other charges
due hereunder, or otherwise defaults with respect to any provision of this
Lease, Lessor may use, apply or retain all or any portion of said deposit for
the payment of any rent or other charge in default or for the payment of any
other sum to which Lessor may become obligated by reason of Lessee's default,
or to compensate Lessor for any loss or damage which Lessor may suffer thereby.
If Lessor so uses or applies all or any portion of said deposit, Lessee shall
within ten (10) days after written demand therefor deposit cash with Lessor in
an amount sufficient to restore said deposit to the full amount then required
of Lessee and Lessee's failure to do so shall be a material breach of this
Lease.  If the monthly rent shall, from time to time, increase during the term
of this Lease, Lessee shall, at the time of such increase, deposit with Lessor
additional money as a security deposit so that the total amount of the security
deposit held by Lessor shall at all times be equal to 150% of the then current
Base Rent.  Lessor shall not be required to keep said security deposit separate
from its general accounts.  If Lessee performs all of Lessee's obligations
hereunder, said deposit, or so much thereof as has not theretofore been applied
by Lessor, shall be returned,

                                       9
<PAGE>   41


without payment of interest or other increment for its use, to Lessee (or, at
Lessor's option, to the last assignee, if any, of Lessee's interest hereunder)
at the expiration of the term hereof, and after Lessee has vacated the
Premises.  No trust relationship is created herein between Lessor and Lessee
with respect to said Security Deposit.

     6.     Use.
            ---

       6.1     Use.  The Premises shall be used and occupied only for
               ---
office, research and development, manufacturing and warehousing and legal
related uses, and for no other purpose, unless such other use shall have been
approved in writing by Lessor.

       6.2     Compliance with Law.
               -------------------

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

        (2)     Except as provided in paragraphs 6.2(a) and 47.3 Lessee shall,
at Lessee's expense, promptly comply with all applicable statutes, ordinances,
rules, regulations, orders, covenants and restrictions of record, and
requirements of any fire insurance underwriters or rating bureaus, now in
effect or which may hereafter come into effect, whether or not they reflect a
change in policy from that now existing, during the term or any part of the
term hereof, relating in any manner to the Premises and the occupation and use
by Lessee of the Premises.  Lessee shall not use nor permit the use of the
Premises in

                                       10
<PAGE>   42


any manner that will tend to create waste or a nuisance or shall tend to
disturb other occupants of the Premises.

       6.3     Conditions of Premises.
               ----------------------

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

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

     7.     Maintenance, Repairs, Alterations and Exterior Area Services.
            ------------------------------------------------------------

       7.1     Lessor's Obligations.  Subject to the provisions of paragraph
               --------------------
4.2 (Operating Expenses), 6 (Use), 7.2 (Lessee's Obligations) 7.5, (Condition
of Premises Upon Termination) and 9 (Damage or Destruction) and except for
damage caused by any negligent or intentional act or

                                      11
<PAGE>   43


omission of Lessee, Lessee's employees, suppliers, shippers, customers, or
invitees, in which event (subject to paragraph 8.7) Lessee shall repair the
damage, Lessor, (i) at Lessor's expense, shall keep in good condition and
repair the Lessor Structural Elements and (ii) shall keep in good condition and
repair, subject to reimbursement pursuant to paragraph 4.2, the other elements
of the Premises, as well as the parking lots, walkways, driveways, landscaping,
fences, signs and utility installations of the Exterior Areas and all parts
thereof.  Lessor shall not, however, be obligated to paint the exterior or
interior surface of exterior walls, nor shall Lessor be required to maintain,
repair or replace windows, doors or plate glass of the Premises, or to maintain
or repair anything required to be maintained by Lessee under paragraph 7.2.
Lessor shall have no obligation to make repairs under this paragraph 7.1 until
a reasonable time after receipt of written notice from Lessee of the need for
such repairs.  Lessee expressly waives the benefits of any statute now or
hereafter in effect which would otherwise afford Lessee the right to make
repairs at Lessor's expense or to terminate this Lease because of Lessor's
failure to keep the Premises in good order, condition and repair.  Lessor shall
not be liable for damages or loss of any kind or nature by reason of Lessor's
failure to furnish any services when such failure is caused by accident,
breakage, repairs, strikes, lockout, or other labor disturbances or disputes of
any character or by any other cause beyond the reasonable control of Lessor.

       7.2     Lessee's Obligations.
               --------------------

        (1)     Subject to the provisions of paragraphs 4.3, 4.4, 6 (Use), 7.1
(Lessor's Obligations), 7.2(d) and 9 (Damage or Destruction), Lessee, at
Lessee's expense, shall keep in good order, condition and repair the Premises
and every part thereof (whether or not the damaged portion of the Premises or
the means of repairing the same are reasonably or readily accessible to Lessee)
including, without limiting the generality of the foregoing, any plumbing,
heating, ventilating and air conditioning systems (Lessee shall procure and
maintain, at Lessee's expense, a ventilating and air conditioning system
maintenance contract), electrical and lighting facilities and equipment within
the Premises, or that serves only the Premises wherever situated, fixtures,
interior walls and interior surfaces of exterior walls, ceilings, windows,
doors, plate glass, and skylights located within the Premises.  Lessor reserves
the right to procure and maintain the ventilating and air conditioning system
maintenance contract and if Lessor so elects,

                                      12
<PAGE>   22


Lessee shall reimburse Lessor, upon demand for the cost thereof.

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

        (3)     On the last day of the term hereof, or on any sooner
termination, Lessee shall, subject to paragraph 7.3(f), surrender the Premises
to Lessor in the same condition as received, ordinary wear and tear excepted,
clean and free of debris.  Any damage or deterioration of the Premises shall
not be deemed ordinary wear and tear if the same could have been prevented by
good maintenance practices.  Lessee shall repair any damage to the Premises
occasioned by the installation or removal of Lessee's trade fixtures,
alterations, furnishings and equipment.  Notwithstanding anything to the
contrary otherwise stated in this Lease, Lessee shall leave the air lines,
power panels, electrical distribution systems, lighting fixtures, space
heaters, air conditioning, plumbing and fencing on the Premises in good
operating condition.

       7.3     Alterations and Additions.
               -------------------------

        (1)     Lessee shall not, without Lessor's prior written consent make
any alterations, improvements, additions, or Utility Installations in, on or
about the Premises, except for nonstructural alterations to the Premises not
exceeding $25,000 in cumulative costs, during the term of this Lease.  In any
event, whether or not in excess of $25,000 in cumulative cost, Lessee shall
make no change or alteration to the exterior of the Premises nor the exterior
of the Building without Lessor's prior written consent.  As used in this
paragraph 7.3 the term "Utility Installation" shall mean carpeting, window
coverings, air lines, power panels, electrical distribution systems, lighting
fixtures, space heaters, air conditioning, plumbing, and fencing.  Lessor may
require that Lessee remove any or all of said alterations, improvements,
additions or Utility Installations at the

                                       13
<PAGE>   44


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

        (2)     Any alterations, improvements, additions, or Utility
Installations made by Lessee during the term of this Lease shall be done in a
good and workmanlike manner and of good and sufficient materials, and Lessee
shall, within thirty (30) days after completion of such alteration,
improvements, addition or Utility Installation, provide Lessor with as-built
plans and specifications for same.  Notwithstanding anything contained in this
Lease to the contrary, Paragraphs 7.3(d)(i)(bb) and (cc) shall apply to non-
structural alterations, improvements, additions or Utility Installations not
exceeding $25,000.00 in cost.

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

        (4)     For any additions, alterations, improvements, or Utility
Installations requiring Lessor's prior written consent:

        (1)     Lessee shall:

(aa)     Request Lessor's approval in writing at least thirty (30) days prior
to proposed construction.

                                       14
<PAGE>   45


(bb)     Employ a California licensed architect, contractor and structural
engineer in connection with the proposed construction.

(cc)     Be fully responsible for the acts of Lessee's consultants, employees,
contractors, subcontractors, invitees and agents, and cause them to fully
comply with any applicable terms of this Lease and documents referred to by
this Lease and all applicable laws, rules and regulations.

(dd)     Enter into written agreements with an architect and general contractor
on standard American Institute of Architects (AIA) form or reasonable
equivalent for the contract itself as well as payment schedules, change orders,
etc.  Copies of executed agreements will be forwarded to Lessor within five (5)

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

property of Lessee and (ii) Lessee's installed refrigeration equipment,

earlier termination of the Lease.  Any items that Lessor does not require to be
removed and that Lessee elects not to remove shall become the property of
Lessor.

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

       7.5     Condition of Premises Upon Termination; Additional.
               --------------------------------------------------

        7.5.1     Lessee shall maintain the Premises as provided in Paragraph
7.2 and in accordance with the requirements of any covenants or restrictions as
may from time to time be applicable to the Premises.  Lessee, in keeping the
Premises in good order, condition and repair, shall exercise and perform good
maintenance practices and any damage or deterioration shall not be deemed
"ordinary wear and tear" if the same could have been prevented by good
maintenance practice.  Lessee's obligations shall include restorations,
replacements or renewals when necessary to keep the Premises and all
improvements thereon or a part thereof in good order, condition and state of
repair.  Notwithstanding anything contained in the Lease to the contrary, but
subject to paragraph 8.7, hereof, Lessee shall make all repairs whatsoever on
the Premises necessitated by the negligence, misconduct or

                                       18
<PAGE>   49


fault of Lessee, or its agents, licensees, contractors or invitees.

        7.5.2     If the term of this Lease, as the same may be extended or
renewed, exceeds five (5) years, Lessor shall have the right to require Lessee
to repaint the interior of the improvements every four (4) to six (6) years,
but not more often that once every five (5) years, as reasonably necessary.

        7.5.3     Notwithstanding anything to the contrary in paragraph 7.2 of
this Lease, upon termination of this Lease, Lessee shall leave all plumbing,
heating (including space heaters), air conditioning, electrical and mechanical
systems, on the Premises and in good condition and operating order, and Lessee
shall upon demand pay to Lessor that portion of the cost to restore such items
to good condition and operating order as may be reasonably allocable to
Lessee's tenancy.

        7.5.4     Notwithstanding anything to the contrary contained in this
Lease, the Premises shall not be used for the warehousing or distribution of
hazardous or explosive products, substances or materials, or of products,
substances or materials that are detrimental to the Premises.

     8.     Insurance; Indemnity.
            --------------------

       8.1     Lessee hereby agrees to indemnify, defend and hold harmless
Lessor, its successors, assigns, subsidiaries, directors, officers, agents and
employees from and against any and all damage, loss, liability or expense
including, but not limited to, attorney's fees and legal costs suffered by same
directly or by reason of any claim, suit or judgement brought by or in favor of
any person or persons for damage, loss or expense due to, but not limited to,
bodily injury, including death resulting anytime therefrom, and property damage
sustained by such person or persons which arises out of, is occasioned by or in
any way attributable to the use or occupancy of the Premises by the Lessee, the
acts or omission of the Lessee, its agents, employees or any other contractors
or invitees brought onto said Premises by the Lessee, or any breach or default
in the performance of any obligation on Lessee's part to be performed under the
terms of this Lease, except to the extent caused by the gross negligence or
wilful misconduct of Lessor, its employees, or agents.  If any action or
proceeding is brought against Lessor by reason of any such claim, Lessee, upon
notice from Lessor, shall defend same at Lessee's expense by counsel
satisfactory to Lessor.  Such loss or damage shall include, but not be limited
to, any injury or

                                       19
<PAGE>   50


damage to Lessor's personnel (including death resulting anytime therefrom) on
the Premises.  Lessor shall not be liable for any damages arising from any act
or neglect of any other tenant, if any, of the building or industrial park in
which the Premises are located.  Lessee agrees that the obligations assumed
herein shall survive the termination of this Lease.

       8.2     Lessee hereby agrees to maintain in full force and effect at all
times during the term of this Lease, at Lessee's own expense, for the
protection of Lessee, Lessor and Lessor's property manager, as their interest
may appear, policies of insurance issued by a responsible carrier or carriers
which afford the following coverages:

        (1)     Workers' Compensation with statutory limits.

        (2)     Employers' Liability insurance with the following minimum
limits:

Bodily injury by disease per person                    $1,000,000
Bodily injury by accident policy limit                 $1,000,000
Bodily injury by disease policy limit                  $1,000,000


        (3)     Property insurance on a special causes of loss insurance form
covering any and all personal property of Lessee including but not limited to
improvements, betterments, furniture, fixtures, Utility Installations, and
equipment in an amount not less than their full replacement cost, with a
deductible not to exceed $10,000.  This policy should contain a waiver of
subrogation.

        (4)     Commercial General Liability Insurance including Broad Form
Property Damage and Contractual Liability with the following minimum limits:

General Aggregate                                      $2,000,000

                                                        person

        (5)     Umbrella/Excess Liability on a following form basis with the

Each Occurrence                                        $5,000,000

                                       20
<PAGE>   51


The limits of said insurance in this Paragraph 8.2 shall not, however, limit
the liability of Lessee hereunder.

       8.3     If Lessor is providing property insurance on the Premises, then
Lessor shall, at all times during the term of this Lease, maintain the
following insurance:

        (1)     a policy or policies of all-risk property insurance, issued by
and binding upon some solvent insurance company, insuring for the full
replacement cost of the building on the Premises.  Lessor shall not be
obligated to insure, and shall not assume any liability or risk of loss for,
any of Lessee's furniture, equipment, machinery, goods, supplies, utility
installations, improvements, or alterations upon the Premises.  This policy
shall contain an agreed amount endorsement and be written with no coinsurance.
Lessor may, but shall not be obligated to, obtain earthquake and flood
insurance.

        (2)     Rent insurance on an all-risk basis in an amount equal to all
that is called for under Paragraph 4 of this Lease (Base Rent and any
additional rents payable under this Lease including tax and insurance costs)
for a period of at least twelve (12) months commencing with the date of loss.

        (3)     Boiler and machinery insurance in an amount satisfactory to
Lessor on a comprehensive coverage form.

       8.4     The Lessee shall deliver to Lessor prior to taking possession of
the Premises, and thereafter at least thirty (30) days prior to expiration of
such policy, certificates of insurance evidencing the above coverage with
limits not less than those specified above.  Lessor shall likewise deliver to
Lessee prior to Lessee's taking possession of the Premises, certificates of
insurance evidencing the above coverage required to be maintained by Lessor.
Insurance required hereunder shall be in companies holding a "General
Policyholders Rating" of at least A-VIII as set forth in the most current issue
of "Best's Insurance Guide".  Such Certificates with the exception of Worker's
Compensation, shall name Lessor, its subsidiaries, directors, agents and
employees, and its property manager as additional insureds and shall expressly
provide that the interest of same herein shall not be affected by a breach by
Lessee of any insurance policy provision for which such Certificates evidence
coverage.  Further, all Certificates shall expressly provide that no less than
ten (10) days prior written notice shall be given to Lessor in the event of
material alteration to or cancellation of the coverage evidenced by such
Certificates.

       8.5     Lessor may secure and maintain, at Lessee's expense, increased
amounts of insurance and other insurance

                                       21
<PAGE>   52


coverage in such limits, as Lessor may require in its reasonable judgment to
afford Lessor adequate protection, consistent with the practices of
institutional owners of comparable properties.

       8.6     Lessor makes no representation that the limits of liability
specified to be carried by Lessee under the term of this Lease are adequate to
protect Lessee against Lessee's undertaking under this Paragraph 8 and in the
event Lessee believes that any such insurance coverage called for under this
Lease is insufficient, Lessee shall provide, at its own expense, such
additional insurance as Lessee deems adequate.


       8.7     Anything in this Lease to the contrary notwithstanding, Lessor
and Lessee hereby waive and release each other of and from any and all rights
of recovery, claims, action or cause of action, against each other, their
agents, officers and employees, for any loss or damage that may occur to the
Premises, improvements to the building of which the Premises are a part,
personal property (building contents) within the building on the Premises, any
furniture, equipment, machinery, goods or supplies not covered by this Lease
which Lessee may bring or obtain upon the Premises or any additional
improvements which Lessee may construct on the Premises, by reason of fire, the
elements or any other cause which could be insured against under the terms of
all risk property insurance policies, regardless of cause or origin, including
negligence of Lessor or Lessee and their agents, officers and employees.
Because this Paragraph will preclude the assignment of any claim mentioned in
it by way of subrogation (or otherwise) to an insurance company (or any other
person) each party to this Lease agrees immediately to give to each insurance
company, written notice of the terms of the mutual waivers contained in this
Paragraph, and to have the insurance policies properly endorsed if necessary to
prevent the invalidation of the insurance coverages by reason of the mutual
waivers contained in this Paragraph.  Lessee also waives and releases Lessor,
its agents, officers and employees of and from any and all rights of recovery,
claim, action or cause of action for any loss or damage insured against under
any other policies of insurance carried by Lessee.

       8.8     Payment of Premium Increase.
               ---------------------------

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

                                       22
<PAGE>   53


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

       8.9     Exemption of Lessor from Liability.  Lessee hereby agrees that
               ----------------------------------
Lessor shall not be liable for injury to Lessee's business or any loss of
income therefrom or for damage to the goods, wares, merchandise or other
property of Lessee, Lessee's employees, invitees, customers, or any other
person in or about the Premises, nor shall Lessor be liable for injury to the
person of Lessee, Lessee's employees, agents or contractors, whether such
damage or injury is caused by or results from fire, steam, electricity, gas,
water or rain, or from the breakage, leakage, obstruction or other defects of
pipes, sprinklers, wires, appliances, plumbing, air conditioning, or lighting
fixtures, or from any other cause, whether said damage or injury results 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 Lessee.  Subject to Paragraph 8.7, the
foregoing shall not limit Lessor's liability for injuries to natural persons or
damage to property to the extent caused by the sole active negligence or
willful misconduct of Lessor, its employees, agents or contractors.
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.
               -----------

        (1)     "Premises Partial Damage" shall mean if the Premises are
damaged or destroyed to the extent that the cost of repair is less than fifty
percent of the then replacement cost of the Premises.

        (2)     "Premises Total Destruction" shall mean if the Premises are
damaged or destroyed to the extent that the cost of repair is fifty percent or
more of the then replacement cost of the Premises.

        (3)     "Insured Loss" shall mean damage or destruction which was
caused by an event required to be

                                       23
<PAGE>   54


covered by the insurance described in paragraph 8.  The fact that an Insured
Loss has a deductible amount shall not make the loss an uninsured loss.

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

       9.2     Premises Partial Damage.
               -----------------------

        (1)     Insured Loss:  Subject to the provisions of paragraphs 9.4 and
9.5, if at any time during the term of this Lease there is damage which is an
Insured Loss and which falls into the classification of Premises Partial
Damage, then Lessor shall, at Lessor's expense, repair such damage to the
Premises, but not Lessee's fixtures, equipment, tenant improvements or Utility
Installations, as soon as reasonably possible and this Lease shall continue in
full force and effect.

        (2)     Uninsured Loss:  Subject to the provisions of paragraphs 9.4
and 9.5, if at any time during the term of this Lease there is damage which is
not an Insured Loss and which falls within the classification of Premises
Partial Damage, unless caused by a negligent or willful act of Lessee or its
agents, contractors or invitees (in which event, subject to Paragraph 8.7
hereof, Lessee shall make the repairs at Lessee's expense), which damage
prevents Lessee from using the Premises, Lessor may at Lessor's option either
(i) repair such damage as soon as reasonably possible at Lessor's expense, in
which event this Lease shall continue in full force and effect, or (ii) give
written notice to Lessee within thirty (30) days after the date of the
occurrence of such damage of Lessor's intention to cancel and terminate this
Lease as of the date of the occurrence of such damage.  In the event Lessor
elects to give such notice of Lessor's intention to cancel or 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 intention to repair
such damage at Lessee's expense, without reimbursement from Lessor, in which
event this Lease shall continue in full force and effect, and Lessee shall
proceed to make such repairs as soon as reasonably possible.  If Lessee does
not give such notice within such 10-day period this Lease shall be canceled and
terminated as of the date of the occurrence of such damage.

        9.3     Premises Total Destruction.
                --------------------------

                                       24
<PAGE>   55


        (1)     Subject to the provisions of paragraphs 9.4 and 9.5, if at any
time during the term of this Lease there is damage, whether or not it is an
Insured Loss, and which falls into the classification of Premises Total
Destruction, then Lessor may at Lessor's option either (i) repair such damage
or destruction, but not Lessee's fixtures, equipment, tenant improvements or
Utility Installations as soon as reasonably possible at Lessor's expense, and
this Lease shall continue in full force and effect, or (ii) give written notice
to Lessee within thirty (30) days after the date of occurrence of such damage
of Lessor's intention to cancel and terminate this Lease, in which case this
Lease shall be canceled and terminated as of the date of the occurrence of such
damage.

       9.4     Damage Near End of Term.
               -----------------------

        (1)     Subject to paragraph 9.4(b), if at any time during the last six
months of the term of this Lease there is substantial damage, whether or not an
Insured Loss, which falls within the classification of Premises Partial Damage,
Lessor may at Lessor's option cancel and terminate this Lease as of the date of
occurrence of such damage by giving written notice to Lessee of Lessor's
election to do so within 30 days after the date of occurrence of such damage.

        (2)     Notwithstanding paragraph 9.4(a), in the event that Lessee has
an option to extend or renew this Lease, and the time within which said option
may be exercised has not yet expired, Lessee shall exercise such option, if it
is to be exercised at all, no later than twenty (20) days after the occurrence
of an Insured Loss falling within the classification of Premises Partial Damage
during the last six months of the term of this Lease.  If Lessee duly exercises
such option during said twenty (20) day period, Lessor shall, at Lessor's
expense, repair such damage, but not Lessee's fixtures, equipment or tenant
improvements, as soon as reasonably possible and this Lease shall continue in
full force and effect provided Lessee first deposits with Lessor any shortfall
in necessary funds.  If Lessee fails to exercise such option during said twenty
(20) day period, then Lessor may at Lessor's option terminate and cancel this
Lease as of the expiration of said twenty (20) day period by giving written
notice to Lessee of Lessor's election to do so within ten (10) days after the
expiration of said twenty

                                       25
<PAGE>   56


(20) day period, notwithstanding any term or provision in the grant of option
to the contrary.

       9.5     Abatement of Rent; Lessee's Remedies.
               ------------------------------------

        (1)     In the event Lessor repairs or restores the Premises pursuant
to the provisions of this paragraph 9, the rent payable hereunder for the
period during which such damage, repair or restoration continues shall be
abated in proportion to the degree to which Lessee's use of the Premises is
impaired to the extent Lessor receives proceeds from rent abatement insurance.
Except for abatement of rent, if any, Lessee shall have no claim against Lessor
for any damage suffered by reason of any such damage, destruction, repair or
restoration.

        (2)     If Lessor shall be obligated to repair or restore the Premises
under the provisions of this paragraph 9 and shall not commence such repair or
restoration within ninety (90) days after such obligation shall accrue, Lessee
may at Lessee's option cancel and terminate this Lease by giving Lessor written
notice of Lessee's election to do so at any time prior to the commencement of
such repair or restoration.  In such event this Lease shall terminate as of the
date of such notice.  In the event that Lessor shall be obligated to repair or
restore the Premises pursuant to Paragraph 9 of this Lease and shall not
commence such repair or restoration within ninety (90) days after such
obligation shall accrue, the right of Lessee to terminate this Lease pursuant
to this Paragraph 9.5(b) shall be the sole right and remedy of Lessee against
Lessor, and Lessor shall have no other liability to Lessee, for damages,
specific performance or otherwise, in connection with any such failure.

        (3)     Lessor shall promptly (in any event, within 30 days after
becoming aware of any damage) notify Lessee in writing as to how long it will
take to substantially restore the damage Lessor shall be obligated to or shall
elect to undertake under the provisions of this paragraph 9 as estimated by
Lessor's architect and/or contractor.  Lessor's failure to so notify Lessee
within such 30 day period, where such failure continues for an additional 10
days after notice thereof from Lessee, shall if Lessee so chooses be deemed to
be the contractor's determination that such restoration will take longer than
270 days (measured from the date of the casualty).

                                       26
<PAGE>   57


        (4)     If any repair or restoration Lessor shall be obligated to or
shall elect to undertake under the provisions of this Paragraph 9 is estimated
by Lessor's architect or contractor to take more than 270 days from the event
of damage to complete, either party at such party's election, may cancel and
terminate this Lease by giving the other party written notice of the electing
party's election to do so at any time prior to the commencement of such repair

in addition, return to Lessee so much of Lessee's security deposit as has not

               ------
which relate to termination of leases when leased property is destroyed and

"real property tax" shall also include any tax, fee, levy, assessment or charge
(i) in substitution of, partially or totally, any tax, fee, levy, assessment or
charge hereinabove included within the definition of "real property tax,"  or
(ii) the nature of which was hereinbefore included within the definition of
"real property tax" or (iii) which is imposed for a service or right not

        (2)     If any of Lessee's said personal property shall be assessed

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

<PAGE>   59


property taxes or assessments applicable to all or any portion of the Premises
and to seek a reduction in the assessed valuation of all or any portion of the
Premises (collectively, "Tax Contests").  Any refund of real property taxes
resulting from any such Tax Contest shall be applied first to reimburse Lessor
for its costs and expenses in connection with the Tax Contest (including,
without limitation attorneys' fees and the costs of consultants) and then, out
of and to the extent of the balance of such refund, Lessor shall reimburse to
Lessee the portion of such reduction attributable to the Premises and the term
of this Lease, as and to the extent previously paid by Lessee as part of
Lessee's Share of Operating Expenses.  Fees payable to tax consultants and
attorneys for consultation and contesting real property taxes shall be an
Operating Expense.  In the event that Lessor has not undertaken a Tax Contest
with respect to the property taxes or assessments for a tax fiscal year, Lessee
may request that Lessor undertake such a Tax Contest.  In the event that Lessor
does not commence such Tax Contest within 90 days after receipt of Lessee's
request or does not otherwise agree to proceed with that Tax Protest, then
Lessee may undertake a Tax Contest; provided that no such Tax Contest by Lessee
shall be made if the contested tax or assessment may become a lien on the
Building or the Industrial Center unless the contested amount is paid prior to
the Tax Contest by Lessee.  Lessee shall indemnify and hold Lessor harmless
with respect to any increases in real property taxes or assessments arising out
of Lessee's conduct of a Tax Contest above the level those real estate taxes or
assessments would have been in the absence of such a Tax Contest.

     11.     Utilities.  Lessee shall pay for all water, gas, heat, light,
             ---------

together with any taxes thereon.

     12.     Assignment and Subletting.
             -------------------------

       12.1     Lessor's Consent Required.  Lessee shall not voluntarily or by
                -------------------------
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in the Lease or in the Premises,
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold.  Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer, mortgage, encumbrance or
subletting without such consent shall be void, and shall constitute a
noncurable breach of this Lease without the need for notice to Lessee under
paragraph 13.1.  If at any time or from time to time during the term of this
Lease, Lessee desires to assign or sublet all or any part of Lessee's interest
in this Lease or in the Premises, Lessee shall give prior written

                                       29
<PAGE>   60


notice to Lessor setting forth the terms of the proposed assignment or
subletting and the space so proposed to be assigned or sublet.  Such assignment
or sublease shall be subject to, without limitation, all the conditions in this
Paragraph 12 and the following conditions:

        (1)     The assignment or sublease shall be on the terms set forth in
the notice given to Lessor.  Any subsequent changes or modifications will
require Lessor's prior written consent.
        (1)

        (2)     Lessee acknowledges that Lessor's agreement to lease these
Premises to Lessee at the rent and terms stated herein is made in material
reliance upon Lessor's evaluation of this particular Lessee's background,
experience and ability, as well as the nature of the use of the Premises by
this Lessee as set forth in Paragraph 6.  In the event that Lessee shall
request Lessor's written consent to assign or sublease the Premises as required
in this Paragraph 12.1, then each such request for consent shall be accompanied
by the following:

        (1)     Financial statements of the proposed assignee or sublessee;

        (2)     A statement of the specific uses for which the Premises will be
utilized by the proposed assignee or sublessee; and

        (3)     Preliminary plans prepared by an architect or civil engineer
for all alterations to the Premises that are contemplated to be made by Lessee,
the proposed assignee or sublessee.

        (3)     No assignment or sublease shall be valid and no assignee or
sublessee shall take possession of the Premises assigned or subleased until an
executed counterpart of such assignment or sublease has been delivered to
Lessor.

        (4)     No sublessee or assignee shall have a right further to sublet
or assign.

        (5)     In the case of an assignment, 75% of any sums or other economic
consideration received by Lessee as a result of such assignment (excluding any
bona fide payments made by an assignee for Lessee-owned property in the
Premises) shall be paid to Lessor after first deducting the unamortized cost of
leasehold improvements

                                       30
<PAGE>   61


paid for by Lessee and the cost of any real estate commissions incurred by
Lessee in connection with such assignment.

        (6)     In the case of a subletting, 75% of any sums or economic
consideration received by Lessee as a result of such subletting (excluding any
bona fide payments made by a sublessee for Lessee-owned property in the
Premises) shall be paid to Lessor after first deducting (i) the Base Rent and
Additional Rent due hereunder prorated to reflect only rent allocable to the
sublet portion of the Premises, (ii) the cost of tenant improvements made to
the sublet portion of the Premises at Lessee's cost, amortized over the term of
this Lease except for tenant improvements made for the specific benefit of the
sublessee, which shall be amortized over the term of the applicable sublease
and (iii) the cost of any real estate commissions incurred by Lessee in
connection with such subletting, amortized over the term of the sublease.

       12.2     Lessee Affiliate.  Notwithstanding the provisions of paragraph
                ----------------
12.1 hereof, Lessee may assign or sublet the Premises, or any portion thereof,
without Lessor's consent, and without any participation by Lessor in the
proceeds relating to such assignment or subletting, to any corporation which
controls, is controlled by or is under common control with Lessee, or to any
corporation resulting from the merger or consolidation with Lessee, or to any
person or entity which acquires all the assets of Lessee as a going concern of
the business that is being conducted on the Premises, all of which are referred
to as "Lessee Affiliate," provided that before such assignment shall be
effective said assignee shall assume, in full, the obligations of Lessee under
this Lease.  Any such assignment shall not, in any way, affect or limit the
liability of Lessee under the terms of this Lease, even if after such
assignment or subletting the terms of this Lease are materially changed or
altered without the consent of Lessee, the consent of whom shall not be
necessary; provided, in that event Lessee shall not be liable for any increase
in the obligations under this Lease resulting from an amendment or modification
of this Lease to which Lessee has not consented.
 .

       12.3     Lessees Other Than Individuals.
                ------------------------------

        (1)     If Lessee is a partnership, a transfer of any interest of a
general partner, a withdrawal of any general partner from the partnership, or
the dissolution of the partnership, shall be deemed to be an assignment of this
Lease.

                                       31
<PAGE>   62


        (2)     If Lessee is a corporation, unless Lessee is a public
corporation whose stock is regularly traded on a national stock exchange, or is
regularly traded in the over-the-counter market and quoted on NASDAQ, any sale
or other transfer of a percentage of capital stock of Lessee which results in a
change of controlling persons, or the sale or other transfer of substantially
all of the assets of Lessee, shall be deemed to be an assignment of this Lease.

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

       12.5     Terms and Conditions Applicable to Subletting.  Regardless of
                ---------------------------------------------
Lessor's consent, the following terms and conditions shall apply to any
subletting by Lessee of all or any part of the Premises and shall be included
in subleases:

        (1)     Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease heretofore or
hereafter made by Lessee, and Lessor may collect such rent and income and apply
same toward Lessee's obligations under this Lease; provided, however, that
until a default shall occur in the performance of Lessee's obligations under
this Lease, Lessee may, subject to paragraph 12.1(e) receive, collect and enjoy
the rents accruing under such sublease.  Lessor shall not, by reason of this or
any other assignment of

                                       32
<PAGE>   63


such sublease to Lessor nor by reason of the collection of the rents from a
sublessee, be deemed liable to the sublessee for any failure of Lessee to
perform and comply with any of Lessee's obligations to such sublessee under
such sublease.  Lessee hereby irrevocably authorizes and directs any such
sublessee, upon receipt of a written notice from Lessor stating that a default
exists in the performance of Lessee's obligations under this Lease, to pay to
Lessor the rents due and to become due under the sublease, Lessee agrees that
such sublessee shall have the right to rely upon any such statement and request
from Lessor, and that such sublessee shall pay such rents to Lessor without any
obligation or right to inquire as to whether such default exists and
notwithstanding any notice from or claim from Lessee to the contrary.  Lessee
shall have no right or claim against such sublessee or Lessor for any such
rents so paid by said sublessee to Lessor.

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

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

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

        (5)     The consent by Lessor to any subletting shall not constitute a
consent to any subsequent subletting by Lessee or to any assignment or
subletting by the sublessee.  However, Lessor may consent to subsequent
sublettings and assignments of the sublease or any

                                       33
<PAGE>   64


amendments or modifications thereto without notifying Lessee or anyone else
liable on the Lease or sublease and without obtaining their consent and such
action shall not relieve such persons from liability.

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

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


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

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

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

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

       12.6     Attorney's FeesAttorney's Fees.  In the event Lessee shall
assign or sublet the Premises or request the

                                       34
<PAGE>   65


consent of Lessor to any assignment or subletting or if Lessee shall request
the consent of Lessor for any act Lessee proposes to do then Lessee shall pay
Lessor's reasonable attorney's and/or consultants' fees incurred in connection
therewith, such attorney's fees not to exceed $350.00 for each such request.
Notwithstanding anything to the contrary in this Paragraph 12.6, the parties
agree that a payment of $750.00 is a reasonable fee for Lessor's review of
Lessee's request to assign or sublet.

     13.     Default Remedies.
             ----------------

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

        (1)     The vacating or abandonment of the Premises by Lessee; provided
the vacating of the Premises by Lessee shall be a default only in the event it
results in an impairment or limitation on the insurance coverage for the
Premises.


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

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

                                       35
<PAGE>   66


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

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

        (6)     If the performance of Lessee's obligations under this Lease is
guaranteed:  (i) the dissolution 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 assurance or 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

                                       36
<PAGE>   67


payable by Lessee to Lessor upon invoice therefor.  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:


        (1)     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 the leasing commission paid by Lessor applicable to the unexpired
term of this Lease.  The worth at the time of award of the amount referred to
in provisions (i) and (ii) of the prior sentence shall be calculated based on
an interest rate equal to the highest rate permitted by applicable law.  The
worth at the time of award of the amount referred to in provision (iii) of the
prior sentence shall be computed by discounting such amount at the discount
rate of the Federal Reserve Bank of San Francisco at the time of award plus one
percent.  Efforts by Lessor to mitigate damages caused by Lessee's breach of
this Lease shall not waive Lessor's right to recover damages under this
Paragraph.  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 therein the right to recover all or any part thereof in a separate
suit for such rent and/or damages.  If a notice and grace period required under
subparagraphs 13.1(b), (c) or (d)

                                       37
<PAGE>   68


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 subparagraphs 13.1(b), (c) or (d).
In such case, the applicable grace period under subparagraphs 13.1(b), (c) or
(d) and under the unlawful detainer statute shall run concurrently after the
one such statutory notice, and the failure of Lessee to cure the default within
the greater of the two such grace periods shall constitute both an unlawful
detainer and breach of this Lease entitling Lessor to the remedies provided for
in this Lease and/or by said statute.

        (2)     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 abandonment and recover the rent as it becomes due, provided Lessee
has the right to sublet or assign, subject only to reasonable limitations.  See
Paragraphs 12 and 36 for the limitations on assignment and subletting which
limitations Lessee and Lessor agree are reasonable.  Acts of maintenance or
preservation, efforts to relet the Premises, or the appointment of a receiver
to protect the Lessor's interest under the Lease, shall not constitute a
termination of the Lessee's right to possession.

        (3)     Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the State of California.  Unpaid
installments of rent and other unpaid monetary obligations of Lessee under the
terms of this Lease shall bear interest from the date due at the maximum rate
allowed by law.

        (4)     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     Default by Lessor.  Lessor shall not be in default unless
                -----------------
Lessor fails to perform obligations required of Lessor within a reasonable
time, but in no event later than thirty (30) days after written notice by
Lessee to Lessor and to the holder of any first mortgage or deed of trust
covering the Premises whose name and address shall have theretofore been
furnished to Lessee in writing, specifying wherein Lessor has failed to perform
such

                                       38
<PAGE>   69


obligation; provided, however, that if the nature of Lessor's obligation is
such that more than thirty (30) days are required for performance then Lessor
shall not be in default if Lessor commences performance within such thirty (30)
day period and thereafter diligently prosecutes the same to completion.

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


     14.     Condemnation.  If the Premises or any portion thereof is taken
             ------------
under the power of eminent domain, or sold under the threat of the exercise of
said power (all of which are herein called "condemnation"), this Lease shall
terminate as to the part so taken as of the date the condemning authority takes
title or possession, whichever first occurs.  If more than ten percent of the
floor area of the Premises, or more than twenty-five percent of that portion of
the Exterior Area designated as parking for the Premises is taken by
condemnation, Lessee may, at Lessee's option, to be exercised in writing only
within ten (10) days after Lessor shall have given Lessee written notice of
such taking (or in the absence of such notice, within ten (10) days after the
condemning authority shall have taken possession) terminate this Lease as of
the date the condemning authority takes such possession.  If Lessee does not
terminate this Lease in accordance with the foregoing, this Lease shall remain
in full force and effect as to the portion of the

                                       39
<PAGE>   70


Premises remaining, except that the rent shall be reduced in the proportion
that the floor area of the Premises taken bears to the total floor area of the
Premises.  No reduction of rent shall occur if the only area taken is that
which does not have the Premises located thereon.  Any award for the taking of
all or any part of the Premises under the power of eminent domain or any
payment made under threat of the exercise of such power shall be the property
of Lessor, whether such award shall be made as compensation for diminution in
value of the leasehold or for the taking of the fee, or as severance damages;
provided, however, that Lessee shall be entitled to any award for loss of or
damage to Lessee's trade fixtures and removable personal property.  In the
event that this Lease is not terminated by reason of such condemnation, Lessor
shall to the extent of severance damages received by Lessor in connection with
such condemnation, repair any damage to the Premises caused by such
condemnation except to the extent that Lessee has been reimbursed therefor by
the condemning authority.  Lessee shall pay any amount in excess of such
severance damages required to complete such repair.

15.     Broker's Commissions.
        --------------------

Lessee and Lessor each represent and warrant to the other that neither has had
any dealings with any person, firm, broker or finder (other than those persons,
if any, whose names are set forth at the end of this paragraph 15) in
connection with the negotiation of this Lease and/or the consummation of the
transaction contemplated hereby, and no other broker or other person, firm or
entity is entitled to any commission or finder's fee in connection with said
transaction and Lessee and Lessor do each hereby indemnify and hold the other
harmless from and against any costs, expenses, attorneys' fees or liability for
compensation, commission 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.  Named brokers:

       Lessor's Broker:     CB Richard Ellis, Inc.

       Lessee's Broker:     Grubb & Ellis

The commission payable to Lessor's Broker with respect to this Lease shall be
paid by Lessor pursuant to the terms of the separate commission agreement in
effect between Lessor and Lessor's Broker.  Lessor's Broker shall pay a portion
of its commission to Lessee's Broker, if so provided in any agreement between
Lessor's Broker and Lessee's Broker.  Nothing in this Lease shall impose any
obligation on Lessor to pay a commission or fee to any party other than
Lessor's Broker or any other party

                                       40
<PAGE>   71


claiming a right to a commission as a result of such broker's activities on
behalf of Lessor.

     16.     Estoppel Certificate.
             --------------------

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

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

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

     17.     Lessor's Liability.  The term "Lessor" as used herein shall mean
             ------------------
only the owner or owners, at the time in question, of the fee title or a
lessee's interest in a ground lease of the Premises, in the event of any
transfer of such title or interest.  Lessor herein named (and in case of any
subsequent transfers then the grantor) shall be relieved

                                       41
<PAGE>   72


from and after the date of such transfer of all liability as respects Lessor's
obligations thereafter to be performed, provided that any funds in the hands of
Lessor or the then grantor at the time of such transfer, in which Lessee has an
interest, shall be delivered to the grantee.  The obligations contained in this
Lease to be performed by Lessor shall, subject as aforesaid, be binding on
Lessor's successors and assigns, only during their respective periods of
ownership.

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

     19.     Interest on Past-due Obligations.  Except as expressly herein
             --------------------------------
provided, any amount due to Lessor not paid when due shall bear interest at the
lesser of 12% or the maximum rate then allowable by law from the date due.
Payment of such interest shall not excuse or cure any default by Lessee under
this Lease; provided, however, that interest shall not be payable on late
charges incurred by Lessee.

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

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

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

                                       42
<PAGE>   73


in effect during the term of this Lease except as otherwise specifically stated
in this Lease.

     23.     Notices.  Any notice required or permitted to be given hereunder
             -------
shall be in writing and shall be personally delivered, delivered by Federal
Express or comparable overnight courier, providing written evidence of
delivery, or delivered by U.S. registered or certified mail, return receipt
requested, postage prepaid and if given personally or by mail, shall be deemed
sufficiently given if addressed to Lessee or to Lessor at the addresses noted
below.  Either party may by notice to the other specify a different address for
notice purposes except that upon Lessee's taking possession of the Premises,
the Premises shall constitute Lessee's address for notice purposes.  A copy of
all notices required or permitted to be given to Lessor hereunder shall be
concurrently transmitted to such party or parties at such addresses as Lessor
may from time to time hereafter designate by notice to Lessee.

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

     25.     Recording.  Lessee shall not record this Lease.
             ---------

     26.     Holding Over.  If Lessee, with Lessor's consent, remains in
             ------------
possession of the Premises or any part thereof after the expiration of the term
hereof, such occupancy shall be a tenancy from month to month upon all of the
provisions of this Lease pertaining to the obligations of Lessee, except that
the monthly rent shall be 150% of the rent payable in the last month of the
lease term but all Options, if any, granted under the terms of this Lease shall
be deemed terminated and be of no further effect during said month to month
tenancy.

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

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

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

     30.     Subordination; Attornment; Non-Disturbance.
             ------------------------------------------

       30.1     Subordination.  This Lease and any Option granted hereby shall
                -------------
be subordinate to any ground lease, mortgage, deed of trust, or other
hypothecation or security device (collectively, "Security Device"), now or
hereafter placed upon the Premises, to any and all advances made on the
security thereof, and to all renewals, modifications, and extensions thereof.
Lessee agrees that the holders of any such Security Devices (in this Lease
together referred to as "Lessor's Lender") shall have no liability or
obligation to perform any of the obligations of Lessor under this Lease.  Any
Lender may elect to have this Lease and/or any Option granted hereby superior
to the lien of its Security Device by giving written notice thereof to Lessee,
whereupon this Lease and such Options shall be deemed prior to such Security
Device, notwithstanding the relative dates of the documentation or recordation
thereof.  Lessor warrants that the Security Devices encumbering the Premises on
the date of this Lease will be released within ten (10) business days after the
Access Delivery Date.
       1.1

       30.2     Attornment.  Subject to the non-disturbance provisions of
                ----------
Paragraph 30.3, Lessee agrees to attorn to a Lender or another party who
acquires ownership of the Premises by reason of a foreclosure of a Security
Device, and that in the event of such foreclosure, such new owner shall not;
(i) be liable for any act or omission of any prior lessor or with respect to
events occurring prior to acquisition of ownership (provided that this clause
(i) shall not relieve the new owner from its ongoing maintenance obligations
under this Lease); (ii) be subject to any offsets or defenses which Lessee
might have against any prior lessor, or (iii) be bound by prepayment of more
than one (1) month's rent.

       30.3     Non-Disturbance-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 a commercially
reasonable non-disturbance agreement (a "Non-Disturbance Agreement") from the
Lender which Non-Disturbance Agreement provides that Lessee's possession of the
Premises, 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.

                                       45
<PAGE>   76


       30.4     Self-Executing-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 the Premises, Lessee and
Lessor shall execute such further writings as may be reasonably required to
separately document any subordination, attornment and/or Non-Disturbance
Agreement provided for herein.

     31.     Attorneys Fees.
             --------------

       31.1     If either party brings an action or proceeding to enforce the
terms hereof or declare rights hereunder, the prevailing party in any such
proceeding, action, or appeal thereon, shall be entitled to his reasonable
attorney's fees and such fees as 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 who obtains legal counsel or brings an action against the
other by reason of the other's breach or default, or who defends such action,
and substantially obtains or defeats the relief sought, whether by compromise,
settlement, judgment, or abandonment of the claim or defense by the other
party.

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

       31.3     Lessor shall be entitled to attorney's fees, costs and expenses
incurred in the 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. Lessor and Lessee agree that $350.00
is a reasonable sum per occurrence for legal services and costs per preparation
and service of a notice of default and that Lessor may include $350.00 as
additional rent due in each such notice of default as an amount that must be
paid to cure said default.

     32.     Lessor's Access.  Lessor and Lessor's agents shall have the right
             ---------------
to enter the Premises at reasonable times for the purpose of inspecting same,
showing the same to prospective purchasers, lenders, or lessees, and making
such alterations, repairs, improvements or additions to the Premises or to the
building of which they are part as Lessor may deem necessary or desirable.
Lessor may at any time place on or about the Premises or the Building any
ordinary "For Sale" signs and Lessor may at any time during the last 120 days
of

                                       46
<PAGE>   77


the term hereof place on or about the Premises any ordinary "For Lease" signs.
All activities of Lessor pursuant to this paragraph shall be without abatement
of rent, nor shall Lessor have any liability to Lessee for the same paid by
Lessor.  Notwithstanding anything to the contrary in this Paragraph 32, except
in the case of emergency or during periods in which Lessee is in default under
this Lease, Lessor shall give Lessee notice at least 2 business days in advance
of Lessor's intent to enter the Premises and such entry shall be made during
Lessee's business hours.

     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 Premises without
             -----
Lessor's prior written consent.  Under no circumstances shall Lessee place a
sign on any roof of the Building.  Lessor shall, at Lessee's sole cost and
expense, install a berm sign in front of the Building identifying its name and
logo.  The graphics, materials, color, design, lettering, size, location and
specifications of Lessee's signage shall be subject to the prior written
approval of Lessor, which approval shall not be unreasonably withheld or
delayed, and the approval of the City of Fremont.  The sign shall be installed
and maintained, at Lessee's sole cost and expense, pursuant to an installation
and maintenance program approved and supervised by Lessor.  At the expiration
or earlier termination of this Lease, Lessor shall, at Lessee's sole cost and
expense, cause the sign to be removed and the berm sign affected by the sign to
be restored to the condition existing prior to the installation of the sign.
Lessor may disapprove any signage that contains a name which relates to an
entity or individual which is of a character or reputation, or is associated
with a political orientation or faction, which is materially inconsistent with
the quality of the Building, or which would otherwise reasonably offend the
landlord of a comparable building or that would conflict with any covenants in
leases of space in the Building.

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

                                       47
<PAGE>   78


     36.     Consents.  Except for paragraphs 46 and 47 hereof, wherever in
             --------
this Lease the consent of one party is required to an act of the other party,
such consent shall not be unreasonably withheld or delayed.

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

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

     39.     Options.
             -------

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

purchase the Premises, or the right of first offer to purchase the Premises, or
the right or option to purchase other property of Lessor, or the right of first
refusal to purchase other property of Lessor or the right of first offer to
purchaser other property of Lessor.

       39.2     Options Personal.  Each Option granted to Lessee in this Lease
                ----------------
is personal to Lessee and may not be exercised or be assigned, voluntarily or
involuntarily, by or to any person or entity other than Lessee, provided,
however, the Option may be exercised by or assigned to any Lessee Affiliate as
defined in Paragraph 12.2 of this Lease or a party holding controlling interest
in the stock of Lessee pursuant to Paragraph 12.3(b).  The Options herein
granted to Lessee are not assignable separate and apart from this Lease.

                                       48
<PAGE>   79


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

       39.4     Effect of Default on Options.
                ----------------------------

        (1)     Lessee shall have no right to exercise an Option,
notwithstanding any provision in the grant of Option to the contrary, (i)
during the time commencing from the date Lessor gives to Lessee a notice of
default pursuant to Paragraphs 13.1(b) or 13.1(c) and continuing until the
default alleged in said notice of default is cured, or (ii) during the period
of time commencing on the day after a monetary obligation to Lessor is due from
Lessee and unpaid (after notice thereof to Lessee) continuing until the
obligation is paid, or (iii) at any time after an event of default described in
Paragraphs 13.1(a), 13.1(d), 13.1(e) or 13.1(f) (without any necessity of
Lessor to give notice of such default to Lessee), or (iv) in the event that
Lessor has given to Lessee three or more notices of default under Paragraph
13.1(b), where a late charge has become payable under Paragraph 13.4 for each
of such defaults, or Paragraph 13.1(c), whether or not the defaults are cured,
during the 12 month period prior to the time that Lessee intends to exercise
the subject Option.

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

        (3)     All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due
and timely exercise of the Option, if, after such exercise and during the term
of this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of
Lessee for a period of 30 days after such obligation becomes due (after notice
thereof to Lessee), or (ii) Lessee fails to commence to cure a default
specified in Paragraph 13.1(c) within 30 days after the date that Lessor gives
notice to Lessee of such default and/or Lessee fails thereafter to diligently
prosecute said cure to completion, or (iii) Lessee commits a default described
in Paragraphs 13.1(a), 13.1(d), 13.1(e) or 13.1(f) (without any necessity of
Lessor to give notice of such default to Lessee), or (iv) Lessor

gives to Lessee three or more notices of default under Paragraph 13.1(b), where
a late charge becomes payable under Paragraph 13.4 for each such default, or
Paragraph 13.1(c), whether or not the defaults are cured.

       39.5     Option.  Lessor hereby grants to Lessee the option to extend
                ------
the term of this Lease for a Five (5) year period commencing on the date the
prior term expires (the "Option Period") upon each and all of the following
terms and conditions:

        (1)     Lessee gives to Lessor, and Lessor actually receives, on a date
which is prior to the date that the Option Period would commence (if exercised)
by at least six (6) and not more than twelve (12) months, a written notice of
exercise of the option to extend this Lease for said additional term, time
being of the essence.  If said notification of the exercise of said option is
not so given and received, this option shall automatically expire;

        (2)     The provisions of Paragraph 39, including the provision
relating to default of Lessee set forth in Paragraph 39.4, of this Lease are
conditions of this option;

        (3)     All of the terms and conditions of this Lease except where
specifically modified by this option shall apply, except that Lessee shall have
no further option to extend the term of this Lease;

        (4)     Any prior Lessee that has not been expressly released from
liability under this Lease, and any guarantor of the Lessee's performance
hereunder, expressly reaffirms in writing the extension of their liability for
the term of the option; and

        (5)     Subject to the annual increase provided for in Paragraph
39.6(a)(vi), the monthly Base Rent for each month of the Option Period shall be
the Fair Market Rent (as defined below) of the Premises as of the commencement
of the Option Period, but in no event less than $123,843.08 per month.

       39.6     Fair Market Rent.
                ----------------

        (1)     The term "Fair Market Rent" as used in this Lease is defined to
mean the rent, including all escalations, at which tenants are leasing non-
sublease, non-encumbered, non-equity space comparable in size and

                                       50
<PAGE>   81


quality to the Premises for the Option Period as to which Fair Market Rent is
being determined in the Ardenwood area of Fremont market, giving appropriate
consideration to the annual rental rates per square foot and the standard of
measurement by which the square footage is measured.  In determining Fair
Market Rent it shall be assumed that:

        (1)     The Premises are in good condition and repair and there shall
be no deduction for depreciation, obsolescence or deferred maintenance (but
less reasonable wear and tear as long as well maintained by Lessee).

        (2)     The Premises would be leased for the period of the option being
exercised by a tenant with the credit standing of Lessee, as the same exists at
that time.

        (3)     The Premises would be leased on the same terms of this Lease
insofar as the obligations for repair, maintenance, insurance and real estate
taxes existed as of the expiration of the original term of this Lease.

        (4)     No deduction shall be given nor consideration given to
allowances for real estate brokerage commissions or free rent.

        (5)     The Premises will be used for its highest and best use.

        (6)     That monthly Base Rent will be increased on each anniversary of
the commencement of the Option Period by an amount equal to 4% of the Base Rent
in effect during the prior year.  (The Fair Market Rent as determined shall
provide for that annual increase.)

        (7)     the Fair Market Rent shall not include in its calculation any
improvements or alterations to the Premises paid for by Lessee in excess of the
Allowance (as defined in Exhibit "C" attached hereto).

        (2)     Determination By Lessor.  Lessor shall initially determine the
Fair Market Rent in each instance, and shall give Lessee notice (the "Market
Rent Notice") of such determination and the basis on which such determination
was made on or before the 60th day prior to

                                       51
<PAGE>   82


the date on which such determination is to take effect, or as soon thereafter
as is reasonably practicable.


        (3)     Disputes re Fair Market Rent.  In the event that Lessee
notifies Lessor in writing, on or before the 20th business day following any
Market Rent Notice, that Lessee disagrees with the applicable determination,
Lessor and Lessee shall negotiate in good faith to resolve such dispute within
10 business days thereafter (The 30th business day after any Market Rent Notice
is referred to herein as the "Outside Agreement Date.")  If not resolved by the
Outside Agreement Date each party shall submit to the other its determination
of Fair Market Rent and the dispute shall be submitted to arbitration in
accordance with the following paragraph titled "Arbitration Procedures."  Until
any such dispute is resolved, any applicable payments due under this Lease
shall correspond to Lessor's determination and, if Lessee's determination
becomes the final determination, Lessor shall refund any overpayments to
Lessee, within 5 business days following the final resolution of the dispute.

        (4)     Arbitration Procedures.

        (1)     Lessor and Lessee shall each appoint one arbitrator who shall
by profession be a real estate broker who shall have been active over the 5-
year period ending on the date of such appointment in the leasing of properties
similar to the Premises in the surrounding area of the County in which the
Premises are located.  The determination of the arbitrators shall be limited
solely to the issue of whether Lessor's or Lessee's submitted Fair Market Rent
for the Premises is the closest to the actual Fair Market Rent for the Premises
as determined by the arbitrators, taking into account the requirements of this
subparagraph regarding the same.  Each such arbitrator shall be appointed
within 15 days after the Outside Agreement Date.  Lessor and Lessee may not
consult with either such arbitrator prior to resolution.

        (2)     The two arbitrators so appointed shall within 15 days of the
date of the appointment of the last appointed arbitrator, meet and attempt to
reach a decision as to whether the parties shall use Lessor's or Lessee's
submitted Fair Market Rent, and shall notify Lessor and Lessee of their
decision, if any.

                                       52
<PAGE>   83


        (3)     If the two arbitrators are unable to reach a decision, the two
arbitrators shall, within 30 days of the date of the appointment of the last
appointed arbitrator, agree upon and appoint a 3rd arbitrator who shall be a
broker who shall be qualified under the same criteria set forth hereinabove for
qualification of the initial 2 arbitrators.

        (4)     The 3 arbitrators shall, within 30 days of the appointment of
the 3rd arbitrator, reach a decision as to whether the parties shall use
Lessor's or Lessee's submitted Fair Market Rent, and shall notify Lessor and
Lessee thereof.
        (1)

        (5)     The decision of the majority of the 3 arbitrators shall be
binding upon Lessor and Lessee.

        (6)     If either Lessor or Lessee fails to appoint an arbitrator
within 15 days after the Outside Agreement Date, the arbitrator appointed by
one of them shall reach a decision, notify Lessor and Lessee thereof, and such
arbitrator's decision shall be binding upon Lessor and Lessee.

        (7)     If the 2 arbitrators fail to agree upon and to appoint a 3rd
arbitrator, then the appointment of the 3rd arbitrator shall be dismissed, and
the matter to be decided shall be forthwith submitted to arbitration under the
provisions of the American Arbitration Association, but subject to the
instructions set forth in this Lease.

        (8)     The cost of arbitration shall be paid by Lessor and Lessee
equally.

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

     41.     Easements.  Lessor reserves to itself the right, from time to
             ---------
time, to grant such easements, rights and dedications

                                       53
<PAGE>   84


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

     42.     Performance Under Protest.  If at any time a dispute shall arise
             -------------------------
as to any amount or sum of money to be paid by one party to the other under the
provisions hereof, the party against whom the obligation to pay the money is
asserted shall have the right to make payment "under protest" and such payment
shall not be regarded as a voluntary payment, and there shall survive the right
on the part of said party to institute suit for recovery of such sum.  If it
shall be adjudged that there was no legal obligation on the part of said party
to pay such sum or any part thereof, said party shall be entitled to recover
such sum or so much thereof as it was not legally required to pay under the
provisions of this Lease.

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

     44.     Cashiers Checks.
             ---------------

       44.1     In the event that any check given to Lessor by Lessee shall not
be honored by the bank upon which it is drawn on two or more occasions, then
Lessor, at its option may require all future payments to be made by Lessee
under this Lease to be made by Cashier's Checks.

       44.2     Any payment made by Lessee pursuant to a written notice to pay
or be deemed in default under this Lease shall be made by Cashier's Check.

     45.     Amendments to Lease.
             -------------------

       45.1     At such times as a rental adjustment is made to this Lease by
virtue of any provision of this Lease, the parties shall execute a written
amendment to this Lease to reflect said change.

                                       54
<PAGE>   85


       45.2     Lessee agrees to make any non-monetary modifications to this
Lease that may be required by an institutional mortgagee of Lessor.

     46.     Storage Tanks.
             -------------

       46.1     Notwithstanding anything to the contrary in Paragraph 7.3
hereof, Lessee shall not install storage tanks of any size or shape in the
Premises, above or below ground, without the consent of the Lessor which can be
withheld in Lessor's sole discretion.  If Lessor elects to grant its consent,
Lessor shall have the right to condition its consent upon Lessee agreeing to
give to Lessor such assurances that Lessor, in its sole discretion, deems
necessary to protect itself against potential problems concerning the
installation, use, removal and contamination of the Premises as a result of the
installation and/or use of such tank, including but not limited to the
installation of a concrete encasement for said tank.  Lessee shall comply at
its expense with all applicable permit and/or registration requirements and
repair any damage caused by the installation, maintenance or removal of such
tank.  Upon termination of the Lease, Lessee shall, at its sole cost and
expense, remove any tank from the Premises, remove and replace any contaminated
soil or materials (and compact or treat the same as then required by law) and
repair any damage or change to the Premises caused by said installation and/or
removal.  Nothing contained herein shall be construed to diminish or reduce
Lessee's obligations under Paragraph 47.

       46.2     Lessor shall have the right to employ experts and/or
consultants, at Lessee's expense, to advise Lessor with respect to the
installation, operation, monitoring, maintenance and removal and restoration of
any such tank.

     47.     Hazardous Materials.
             -------------------

       47.1     Lessee's Covenants Regarding Hazardous Materials.
                ------------------------------------------------

        (1)     Lessor's Prior Consent.  Notwithstanding anything contained in
this Lease
                ----------------------

termination of this Lease, Lessee shall, at Lessee's sole cost and expense,
cause all Hazardous Materials brought on the Premises with Lessor's consent to
be removed from the Premises in compliance with all applicable Hazardous
Materials Laws.  If Lessee or its employees, agents, or contractors violates
the provisions of the foregoing two paragraphs, or if Lessee's acts,
negligence, or business operations contaminate, or expand the scope of
contamination of, the Leased Premises from such Hazardous Materials, then
Lessee shall promptly, at Lessee's expense, take all investigatory and/or
remedial action (collectively, the "Remediation") that is necessary in order to
clean up, remove and dispose of such Hazardous Materials causing the violation
on the Leased Premises or the underlying groundwater or the properties adjacent

claims relating to any Hazardous Materials in any way connected with the
Premises, without first notifying Lessor of Lessee's

                                       57
<PAGE>   88


intention to do so and affording Lessor ample opportunity to appear, intervene

        (4)     Notices.  Lessee shall immediately notify Lessor in writing of:
(i) any enforcement, cleanup, removal or other governmental or regulatory
action threatened, instituted, or completed pursuant to any Hazardous Materials
Laws with respect to the Premises; (ii) any claim, demand, or complaint made or
threatened by any person against Lessee or the Premises relating to damage,

       47.3     Preexisting Conditions.  Notwithstanding anything to the
                ----------------------
contrary in this Lease, Lessee shall not be liable to Lessor under this Lease
for any cost associated with Hazardous Materials, if any, to the extent that
(a) the Hazardous Materials existed on the Premises prior to the date of this
Lease and were not brought on to the Premises by Lessee, its agents, employees,
contractors, subcontractors, licensees or invitees (the "Lease Parties") or (b)
any subsurface Hazardous Materials migrate onto the Property from offsite
sources (other than Lessee Parties) after the Commencement Date (collectively
the "Preexisting Conditions").  Lessor hereby reserves the right to enter upon
the Premises at reasonable times to perform any work necessary, or in Lessor's
judgment, advisable in connection with any such Preexisting Conditions, and, so
long as Lessor makes commercially reasonable efforts to minimize interference
with Lessee's operations in the Premises, no such entry or performance of work
shall constitute a constructive eviction or otherwise entitle Lessee to any
damages or reduction in rent, or to terminate this Lease.  The foregoing right
of entry may be exercised by Lessor, its agents, employees, and contractors and
by any person Lessor may identify as being connected with the Preexisting
Conditions, and such person's agents, employees and

                                       58
<PAGE>   89


contractors.  Without limiting any other provision of this Lease, Lessee shall
provide Lessor with the original of any notices or other documents received by

prepared by ATC Associates, (Project No. 75.81075.0002) and any prior hazardous
materials studies described therein ("Hazardous Substance Surveys").  The
Hazardous Substance Surveys do not indicate the presence of Hazardous Materials
at the leased Premises based on the present levels or content of said Hazardous
Materials in the materials sampled and tested at the Building housing the
Premises, as said levels or content are presently set by the U.S. Environmental
Protection Agency ("EPA") or the U.S. Occupational Safety and Health
Administration ("OSHA").  Lessor has no knowledge of Hazardous Materials at the
Premises or in the Building but Lessor's knowledge regarding the absence of
said Hazardous Materials is limited to the Hazardous Substance Surveys.  For
purposes of the preceding sentence, knowledge by Lessor shall be limited to the
actual knowledge of the following persons:  Tig Tarlton.  Lessor, except as
provided in the following sentence of this paragraph, makes no representations
or warranties whatsoever to Lessee regarding:  (i) the Hazardous Substance
Surveys (including, without limitation, the contents and/or accuracy thereof)
or (ii) the presence or absence of toxic or Hazardous Materials in, at, or
under the Premises, the Building or the Industrial Center.  Lessor does
acknowledge to Lessee that:  (i) Lessor has not authorized any other studies
for hazardous or toxic materials at the Premises or Building other than the
Hazardous Substance Surveys; (ii) Lessor does not know of any surveys for toxic
or Hazardous Materials at the Premises or the Building other than the Hazardous
Substance Surveys; and (iii) Lessor does not know of any reason that the
Hazardous Substance Surveys are not true and correct.  Notwithstanding the
preceding sentence, Lessee:  (a) shall not rely on and Lessee hereby represents
to Lessor that it has not relied on the Hazardous Substance Surveys; (b) shall
make such studies and investigations, conduct such tests and surveys, and
engage such specialists as Lessee deems appropriate to fairly evaluate the
Premises and any risks from hazardous or toxic materials.  In connection with
any inspections or tests to be conducted by Lessee at the Premises or Building,
Lessee shall first notify Lessor of each proposed inspection or test and the
scope, impact, and intent thereof and obtain Lessor's written consent to
perform the same.  To the extent such proposed inspection or test causes
physical damage to the Premises, Lessee shall restore the Premises and

                                       59
<PAGE>   90


the property on which the Premises are located to the condition existing
immediately prior to any such test and/or inspection and will provide Lessor
with true and complete copies of any survey or report obtained by or for the
benefit of Lessee in connection with hazardous or toxic materials that concern
the Building or the Premises.

       47.5     Consent to Certain Hazardous Materials.  Pursuant to Paragraph
                --------------------------------------
47.1(a), Lessor hereby consents to the use of the materials described in
Schedule 47.5 so long as Lessee complies with all of the requirements of
Paragraph 47.1 with respect to those permitted materials.

     48.     Lessor's Default.
             ----------------

Any damages or judgments arising out of Lessor's default of its obligations
under this Lease shall be satisfied only out of Lessor's interest and estate in
the Premises, and Lessor shall have no personal liability beyond such interest
and estate with respect to such damages or judgments.

     49.     Recovery of Concessions Upon Early Termination.  In the event that
             ----------------------------------------------
Lessee's right of possession of the Premises is terminated prior to the end of
the initial term by reason of default, legal process, abandonment, or any other
reason other than mutual agreement of the parties or as a result of Lessee
exercising its right to terminate the Lease as provided in this Lease, then
immediately upon such termination, an amount shall be due and payable by Lessee
to Lessor equal to the unamortized portion as of that date (which amortization
shall exclude any Option Terms and shall be based on an interest rate of twelve
percent (12%) per annum) of the sum of (i) the Lessee Improvement Allowance (as
defined in Exhibit C), (ii) the value of the free Base Rent (i.e., the Base
Rent stated in this Lease to be abated as an inducement to Lessee's entering
into this Lease) enjoyed as of that date by Lessee, and (iii) the amount of all
commissions paid by Lessor in order to procure this Lease.

     50.     Easements and Restrictions of Record
             ------------------------------------

       50.1     Lessee accepts the Premises subject to the easements and
covenants or restrictions of record.

       50.2     Lessor and Lessee agree to cooperate and use their best efforts
to participate in traffic management programs generally applicable to
businesses located in the area which includes the Premises and, initially,
shall encourage and support van and car pooling by Lessee's employees to the

                                       60

fullest extent permitted by the requirements of Lessee's business.  Neither
this Paragraph nor any other provision in this Lease, however, is intended to
or shall create any rights or benefits in any other person, firm, company,
governmental entity or the public.

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

     52.     Letter of Credit as Security.
             ----------------------------

       52.1     Letters of Credit.  On or before the date (the "LC Delivery
Date") that is
                -----------------
fourteen days after the Access Delivery Date, Lessee shall deliver to Lessor a
letter of credit (the "Initial Letter of Credit") in the amount of
$1,087,500.00 (the "Letter of Credit Required Amount").  Lessee's failure to
deliver the Initial Letter of Credit by the LC Delivery Date shall be a default
by Lessee under this Lease, without the obligation of Lessor to provide any
notice or opportunity to cure.  Without limiting any of Lessor's rights or
remedies under this Lease, Lessor shall have no obligation to disburse any
portion of the Allowance until the Initial Letter of Credit is delivered to
Lessor.  The Initial Letter of Credit, together with all substitute or
replacement letters of credit delivered to Lessor from time to time pursuant to
this Paragraph 52, are collectively referred to herein as the "Letters of
Credit"; and the issuer of the Initial Letter of Credit, together with the
issuer(s) of all subsequent Letters of Credit, are collectively referred to
herein as the "Issuers."  Each Letter of Credit shall be an irrevocable,
unconditional and transferable letter of credit in the Letter of Credit
Required Amount, shall be issued by a financial institution reasonably
acceptable to Lessor, shall be substantially in the form of Exhibit "B" hereto
and otherwise in form and substance reasonably acceptable to Lessor and,
without limiting the generality of the foregoing, shall permit Lessor to draw
upon it from time to time upon delivery by Lessor to the Issuer of a statement
certifying that either (A)  Lessee has failed to pay or perform one or more of
its obligations under this Lease and/or the Lease Improvement Note (as defined
below), or (B) Lessor is entitled to make a full drawing under the Letter of
Credit as a result of (1) Lessee's failure to timely replace such Letter of
Credit or (2) the termination of the Lease as a result of Lessee's default.
Lessor may draw on the Letter of Credit and/or apply the Security Deposit in
any order.

       52.2     Replacement of Letters of Credit.  The Initial Letter of Credit
                --------------------------------
shall expire no earlier

                                       61
<PAGE>   92


than the one-year anniversary of the Lease Commencement Date.  On or before the
30th day prior to the expiration date of the Initial Letter of Credit and each
subsequent Letter of Credit, Lessee shall deliver a replacement Letter of
Credit to Lessor with the same provisions except that each new Letter of Credit
shall expire no earlier than the one-year anniversary of the expiration of the
previous Letter of Credit (provided that Lessee shall be deemed to have met the
foregoing requirement if Lessee delivers to Lessor a document in form and
substance satisfactory to Lessor which effectively extends the expiration of
the existing Letter of Credit for not less than an additional year).

       52.3     Drawing Upon Failure to Renew.  In the event that, at any time,
                -----------------------------
Lessee fails to timely deliver a replacement Letter of Credit to Lessor in
accordance with Paragraph 52.2, then in such event (and without notice to
Lessee) Lessor shall be entitled to draw the entire outstanding balance of the
unexpired Letter of Credit, which amount may be immediately applied by Lessor
against any amounts then past due and unpaid to Lessor under the Lease and/or
against the outstanding balance of the Lessee Improvement Note, and any
remaining balance shall be held by Lessor as the security deposit under this
Lease (a "Letter of Credit Deposit").  In the event that Lessor draws the
entire balance of the Letter of Credit in accordance with this paragraph,
Lessee shall be deemed to have cured the default resulting from its failure to
provide a replacement Letter of Credit (but subject to Lessee's obligation to
supplement the Letter of Credit Deposit as provided in Paragraph 52.5, below),
and Lessee shall have no further right or obligation to provide a Letter of
Credit in substitution for a cash deposit.

       52.4     Drawing Upon Lease Termination.  In the event that this Lease
                ------------------------------
terminates prior to the scheduled expiration thereof as the result of a default
by Lessee or a default occurs under the Lessee Improvement Note, Lessor shall
be entitled to immediately draw the entire outstanding balance of the current
Letter of Credit and to apply such proceeds against the unpaid balance of the
Lessee Improvement Note.  In the event that Lessor draws the entire balance of
the applicable Letter of Credit (or applies the entire balance of a Letter of
Credit Deposit) following any such Lease termination and such balance is more
or less than the amounts (when finally determined) against which Lessor is
permitted to apply such funds, then the amount of the difference shall be
promptly paid by Lessee to Lessor, or by Lessor to Lessee, as applicable.

       52.5     Reinstatement of Letter of Credit.    In the event that Lessor
                ---------------------------------
draws upon any Letter of

                                       62
<PAGE>   93


Credit in whole or in part, Lessee shall deliver (or cause to be delivered) to
Lessor, on or before the fifth (5th) business day following the later of
Lessee's receipt of notice that Lessor has made (or will make) such draw, or
such draw, evidence satisfactory to Lessor that such Letter of Credit has been
reinstated to the full Letter of Credit Required Amount; provided that Lessee
shall be deemed to have met the foregoing reinstatement requirement if Lessee
delivers a replacement Letter of Credit to Lessor in the Letter of Credit
Required Amount on or before such fifth (5th) business day.  If Lessee fails to
timely reinstate any Letter of Credit, such failure shall constitute an
additional default by Lessee under this Lease, without any notice or
opportunity to cure.  Notwithstanding the foregoing, (i) in the event that
Lessor makes a full drawing of the Letter of Credit as a result of Lessee's
failure to timely deliver a replacement Letter of Credit, Lessee shall not be
obligated to reinstate the Letter of Credit but shall instead be required to
deliver to Lessor from time to time, within three (3) business days following
Lessor's written demand, funds in the amount, if any, by which the Letter of
Credit Required Amount exceeds the balance of the Letter of Credit Deposit, and
(ii) in the event that Lessor makes a full drawing of the Letter of Credit
following the termination of the Lease and/or a default under the Lessee
Improvement Note, the foregoing reinstatement obligation shall not apply (which
shall not be construed as a waiver by Lessor of any damages or other amounts
owing by Lessee in excess of the amounts so drawn by Lessor).

     53.     Lessor Improvements.  Lessor shall perform the following work on
             -------------------
the Premises at Lessor's cost (the "Lessor Improvements"):

       53.1       Deliver all building systems and subsystems (e.g., HVAC,
electrical and plumbing) in good working condition and repair on the
Commencement Date.

       53.2     All modifications to the Premises and Building common areas
(including, without limitation, the restrooms, elevators, parking lot and
exterior entrances) required to bring them into compliance with applicable laws
in effect and enforceable against the Premises on the date of this Lease.

     54.     Lessee Improvements.  Lessee shall construct the Lessee
             -------------------
Improvements pursuant to Exhibit "C" attached hereto, and the applicable
provisions of this Lease.

     55.     Lessee Improvement Loan.  Pursuant to the Work Letter attached
             -----------------------
hereto as Exhibit "C,"

                                       63
<PAGE>   94


Lessor is making the Lessee Improvement Loan to Lessee.  The Lessee Improvement
Loan shall be evidenced by a promissory note (the "Lessee Improvement Note") in
the form and with the terms and conditions of Exhibit "D" attached hereto.  The
Lessee Improvement Note shall be executed and delivered by Lessee concurrently
with Lessee's execution and delivery of this Lease.  A default under the Lessee
Improvement Note shall be a default under this Lease.  At any time after
Lessee's receipt of FDA approval of its "Floseal" product, Lessee may request
that the Lease be amended to recharacterize the then outstanding principal
balance of the Lessee Improvement Note as an improvement allowance.  Within
thirty (30) days after that request, Lessee and Lessor shall enter into an
amendment of this Lease which shall contain the following provisions and shall
otherwise be acceptable to Lessor and Lessee:  (a) Lessee shall agree to pay
improvement rent (the "Improvement Rent") for the balance of the initial term
in a monthly amount equal to $17,774.08, (b) Improvement Rent shall be payable
on the first day of each month of the initial term of this Lease, concurrently
with and in addition to Lessee's obligation for payment of the monthly Base
Rent under Paragraph 4 above, (c) Improvement Rent shall be deemed rental
payments, and Lessee's failure to pay the same shall entitle Lessor to all of
the remedies that are available to Lessor for Lessee's failure in payment of
any Base Rent or other amount due hereunder, (d) the Lessee Improvement Note
shall cease to be effective, and (e) the Letter of Credit shall be modified to
Lessor's satisfaction to provide that Lessor may draw on the Letter of Credit
for any amounts due Lessor from Lessee under this Lease.

LESSOR AND LESSEE HAVE CAREFULLY READ AND REVIEWED THIS LEASE AND EACH TERM AND
PROVISION CONTAINED HEREIN AND, BY EXECUTION OF THIS LEASE, SHOW THEIR INFORMED
AND VOLUNTARY CONSENT THERETO.  THE PARTIES HEREBY AGREE THAT, AT THE TIME THIS
LEASE IS EXECUTED, THE TERMS OF THIS LEASE ARE COMMERCIALLY REASONABLE AND
EFFECTUATE THE INTENT AND PURPOSE OF LESSOR AND LESSEE WITH RESPECT TO THE
PREMISES.

                                EXHIBIT "C"
                                -----------

                           WORK LETTER AGREEMENT
                           ---------------------
                        (Lessee Designs and Builds)

          This Work Letter Agreement, dated, for reference purposes only,
October 7, 1999, supplements the Lease (the "Lease"), dated and executed
concurrently herewith, by and between Lessor and Lessee, covering certain
premises described in the Lease (the "Premises").  All terms not defined herein
shall have the same meaning as set forth in the Lease.

     1.     Construction Representatives.  Lessor hereby appoints L.C. (Tig)
            ----------------------------
Tarlton/Tarlton Properties as Lessor's representative ("Lessor's
Representative") to act for Lessor in all matters covered by this Exhibit "C".
Lessee hereby appoints Scott Huie as Lessee's representative ("Lessee's
Representative") to act for Lessee in all matters covered by this Exhibit "C".
All communications with respect to the matters covered by this Exhibit "C"
shall be made to Lessor's Representative or Lessee's Representative, as the
case may be.  Either party may change its representative under this Exhibit "C"
at any time by written notice to the other party.  Lessee shall enter into a
construction management contract with a qualified contractor (the "Contractor")
reasonably approved by Lessor for the construction of the Lessee Improvements.

     2.     Construction Plans for Premises.  Lessor hereby approves
            -------------------------------
Lessee's engagement of Dowler Gruman, ("Architect") as Lessee's architect on
the Lessee Improvements.  Lessor shall have the right to approve Lessee's
engineers (the "Engineer"), which approval shall not be withheld unreasonably.

       2.1     Preparation of Space Plans.  The Architect shall prepare
               --------------------------
detailed space plans sufficient to convey the architectural design of the
Premises and layout of the Lessee Improvements therein ("Space Plans").  The
Space Plans shall be submitted to Lessor for Lessor's reasonable approval,
which approval shall be granted or withheld by written notice to Lessee
delivered not later than five (5) business days following Lessor's receipt of
the proposed Space Plans.  Lessee acknowledges and agrees that it shall be
reasonable for Lessor to disapprove the Space Plans or Plans if the same do not
include, at a minimum, the types of improvements necessary to operate the
Premises as a first class industrial/office facility, within the budgetary
limits of the Allowance (as defined below).  If Lessor shall disapprove of any
portion of the Space Plans, Lessor shall advise Lessee in writing of such

                                Exhibit "C"
                                Page 1 of 8
<PAGE>   101


disapproval and the reasons therefor.  Lessee shall then submit to Lessor for
Lessor's reasonable approval, a redesign of the Space Plans, incorporating
those revisions required by Lessor, which approval shall be granted or withheld
by written notice to Lessee delivered not later than five (5) business days
following Lessor's receipt of the proposed Space Plans.

       2.2     Preparation of Final Plans.  Based on the approved Space
               --------------------------
Plans, Lessee shall cause the Architect, in consultation with the Engineer, to
prepare architectural plans, drawings and specifications and Lessee shall cause
the Architect to prepare working drawings for the Lessee Improvements (the
"Plans").  All such Plans shall ultimately show:  (a) the subdivision
(including partitions and walls), layout, lighting, finish and decoration work
(including carpeting and other floor coverings) desired by Lessee for the
Premises; (b) all internal and external communications and utility facilities
which will require conducting or other improvements from the Building shell;
and (c) all other specifications for the Lessee Improvements.  The Plans shall
be approved in the same manner as provided in Paragraph 2.1 above for approval
of Space Plans.

       2.3     Requirements of Lessee's Final Plans.  Lessee's Plans as
               ------------------------------------
finalized and approved by Lessor (the "Final Plans") shall include locations
and complete dimensions, and shall:  (a) be compatible with the Building shell
and with the design, construction and equipment of the Building; (b) be
compatible with and of at least equal quality as the standards contained in the
preliminary plans previously delivered to Lessee by Lessor (the "Standards");
and (c) comply with all applicable laws and ordinances, including without
limitation the American's with Disabilities Act and Title 24, and the rules and
regulations of all governmental authorities having jurisdiction, and all
applicable insurance regulations.

       2.4     Changes to Shell of Building.  If the Final Plans or any
               ----------------------------
amendment thereof or supplement thereto shall require changes in the Building
shell or the other Lessor Improvements, the increased cost of the Building
shell work or the other Lessor Improvements caused by such changes shall be
charged against the Lessee Improvement Allowance.

       2.5     Approvals.  Lessee shall be solely responsible for obtaining
               ---------
approval of the Final Plans by the City of Fremont, California, together with
approvals of any other governmental agencies having jurisdiction including all
necessary permits and the temporary and permanent certificate

                                Exhibit "C"
                                Page 2 of 8
<PAGE>   102


of occupancy (or other required, equivalent approval from the local government
authority permitting occupancy of the Premises).  Lessee shall deliver
certified copies of all such permits, approvals and certificates within ten
(10) days of Lessee's receipt thereof, and in any event not later than thirty
(30) days following Lessee's commencement of business from the Premises.
Lessor shall reasonably cooperate with Lessee in obtaining such approvals.


     3.     Allowance for Lessee Improvements.
            ---------------------------------
       2.6     Allowance.  Lessee shall receive from Lessor an allowance
               ---------
(the "Lessee Improvement Allowance") in the amount of $725,000.00, and a loan
(the "Lessee Improvement Loan") in an amount not to exceed $1,087,500.00 which
Lessee Improvement Allowance and Lessee Improvement Loan shall be used solely
to contribute toward payment of the Work Cost (as defined below) of the Lessee
Improvements.  The Lessee Improvement Allowance and the Lessee Improvement Loan
are sometimes referred to herein collectively as the "Allowance".

       2.7     Excess Work Costs.  In the event that the actual Work Costs
               -----------------
exceed the Allowance, Lessee shall pay such excess and Lessor shall have no
responsibility therefor.  Such excess shall be paid in accordance with
Paragraphs 3.4 and 3.5 below.

       2.8     Changes.  In the event that changes to the Space Plans or
               -------
Plans are requested by Lessee or required by any governmental agency subsequent
to Lessor's approval thereof, such changes and the costs thereof shall be
forwarded to Lessor for approval (which approval shall not be unreasonably
withheld) prior to incorporation into the work.  After Lessor's approval of the
changes and the costs thereof, the changes shall be incorporated into the work
by means of a change order.

       2.9     Payment of Allowance.  The Allowance and the Reserve Funds
               --------------------
(as defined below) shall be paid by Lessor in accordance with this Paragraph
3.4.  The Lessee Improvement Allowance shall be fully disbursed prior to any
disbursement of the Lessee Improvement Loan.  Lessor shall pay directly all
fees and costs payable to Lessor's consultants in connection with the review of
the Space Plans and Plans (not to exceed $5,000.00 in the aggregate), which
shall be charged against and payable from the Allowance.  Lessee or Lessee's
general contractor shall provide Lessor, not more often than once per calendar
month, with an invoice prepared by Lessee's general contractor (or Lessee's
Architect with respect to design costs) on the standard AIA forms or in such
other similar form

approved by Lessor setting forth the Work Cost payable since the last such
invoice.  Such invoice shall be accompanied by (i) a certificate from Lessee's
Architect and general contractor certifying that the Work Cost set forth in
such invoice is accurate and that all Work Costs set forth in prior invoices
have been paid, (ii) copies of all invoices from subcontractors setting forth
the Work Cost on Lessee's general contractor's invoice, (iii) receipts from
such subcontractors acknowledging payment of the Work Cost set forth in prior
invoices, and (iv) copies of lien releases and waivers, or conditional lien
releases and waivers, in both Lessor's and Lessee's favor, from Lessee's
general contractor and subcontractors (such releases and waivers shall be
conditional with respect to the Work Cost set forth in the invoice which they
are accompanying and final with respect to the Work Cost on prior invoices).
Lessor shall pay to Lessee's general contractor, or to Lessee's Architect with
respect to design costs, within five (5) business days of receipt of all of the
foregoing, the Work Cost set forth on the invoice, less the amount of the
retention as described in Paragraph 4.1 below, to the extent Lessor, in its
reasonable judgment, deems such Work Cost to be accurate.  Such payment shall
be from the Allowance and the Reserve Funds in the proportions described in
Paragraph 3.5 below.  Upon completion of all work to be undertaken by Lessee,
which completion shall be certified, on the AIA form or in such other similar
form approved by Lessor, by Lessee, the Architect and the Contractor, Lessee
shall execute and deliver to Lessor a written acknowledgment that the Lessee
Improvements are approved by Lessee and a written certificate setting forth the
amount and nature of all costs and expenses billed to Lessee in connection with
the design, permit approval and construction of the Lessee Improvements.
Within ten (10) days after Lessor's receipt of such certificate, accompanied by
copies of all related bills, invoices, receipts and final unconditional lien
releases and unconditional waivers of all lien rights, in recordable form, from
Lessee's contractor and all subcontractors, Lessor shall pay to Lessee the
remaining amount of such cost and expenses which will be due to the actual hold
back provided in the construction contract up to and including, but not
exceeding, the Allowance and the Reserve Funds.  Such payment shall be from the
Allowance and the Reserve Funds in the proportions described in Paragraph 3.5
below.  Within thirty (30) days of the completion of the Lessee Improvements,
Lessee shall deliver to Lessor two (2) complete sets of as-built plans for the
Lessee Improvements.

       2.10    Reserve Fund.  Following Lessor's approval of the Plans,
               ------------
Lessor shall give Lessee notice of Lessor's

                                Exhibit "C"
                                Page 4 of 8
<PAGE>   104


reasonable estimate of the Work Cost.  In the event such estimate exceeds the
Allowance, Tenant shall pay Lessor, within ten (10) days of such notice, an
amount equal to such excess, which amount shall constitute the Reserve Fund.
If at any time thereafter Lessor reasonably increases its estimate of the Work
Cost, Lessor may give notice to Lessee of the amount of such increase and
Lessee shall pay Landlord, within ten (10) days of such notice, such increase,
which amount shall be added to the Reserve Fund.  The Allowance and the Reserve
Funds shall be disbursed in the proportion that each bears to the total
estimated Work Cost.  Accordingly, as to any individual disbursement, the
portion payable out of the Allowance shall equal a percentage determined by
dividing the Allowance by the total estimated Work Cost and the portion
disbursed from the Reserve Funds shall be a percentage determined by dividing
the total amount of the Reserve Funds by the total estimated Work Costs.  In
the event that the estimate of the Work Costs increases, all disbursements
thereafter shall be made entirely from the Reserve Funds until the remaining
amounts in the Allowance and the Reserve Funds are in the same proportions as
existed with respect to the original estimate of Work Costs and Lessee's
initial deposit into the Reserve Fund. Within thirty (30) days after lien free
completion of the Lessee Improvements by Lessee, Lessor will release to Lessee
any undisbursed Reserve Funds.

        2.11    Construction Management Fee.  As part of each disbursement
                ---------------------------
of Allowance and Reserve Funds, a portion of the Construction Management Fees
equal to 2.0% of such disbursement shall also be made.  Upon completion of the
Lessee Improvements, the actual Construction Management Fees shall be
determined and the difference between the actual and estimated Construction
Management Fees shall, as appropriate, be refunded by Tarlton Properties to the
Allowance, or paid to Tarlton Properties from the Allowance.

     4.     Construction.
            ------------

       2.12    Selection of Contractor.  The general contractor (the
               -----------------------
"Contractor") for the Lessee Improvements shall be subject to Lessor's prior
written approval.  Promptly following Lessor's approval of the Final Plans,
Lessee shall enter into a construction contract with the Contractor, which
contract shall provide for (a) a contractor's profit of not more than ten
percent (10%) of the hard costs of the Lessee Improvements, (b) the retention
of a percentage of the monthly progress payments in a commercially reasonable
amount not to exceed ten percent (10%), and shall otherwise be reasonably
approved in

                                Exhibit "C"
                                Page 5 of 8
<PAGE>   105


writing by Lessor within five (5) business days after submittal by Lessee, or
if disapproved, then reasons for such disapproval shall be given to Lessee
within said five (5) business day period.  Lessee shall be solely responsible
for the performance of the work of the Lessee Improvements to be performed by
the general contractor and any and all subcontractors, suppliers and the like
performing services for Lessee and/or the general contractor.

       2.13    Construction Schedule.  Prior to commencement of construction
               ---------------------
of any Lessee Improvements, Lessee shall furnish to Lessor for reasonable
approval in writing a schedule setting forth projected completion dates and
showing the projected approximate deadlines for any actions required to be
taken by Lessor and Lessee during such construction.  Lessor shall exercise
such approval right within two (2) business days after it receives such
schedule.

       2.14    Prosecution of Lessee Improvements.  Following Lessor's
               ----------------------------------
approval of the initial Plans, and execution of the construction contract
pursuant to Subparagraph 4.1 above, Lessee shall direct Lessee's general
contractor and such subcontractors to immediately commence and diligently
complete construction of the Lessee Improvements.  Such work shall be performed
diligently, in a first-class, workmanlike manner and in accordance with all
applicable laws.  Prior to commencing such work, Lessee shall furnish Lessor
with sufficient evidence that Lessee and Lessee's contractor are carrying the
following insurance:  Commercial General Liability in the aggregate amount of
$5,000,000; automobile liability, with a $1,000,000 combined single limit;
workers compensation, in the amount of $1,000,000 for each accident.  Lessee
shall also advise Lessor of the amount of Lessee's contractor's excess
liability coverage.  Such policy shall be endorsed to name the following as
additional insureds:  Lessor, Tarlton-Wohl Venture Nine, LLC, Strategic
Performance Fund-II, and The Prudential Insurance Company of America.  Lessor
shall have the right to enter the Premises at all times to inspect the work and
to post notices of nonresponsibility.  Lessee shall ensure lien-free completion
of the Premises, and Lessee shall comply with all provisions of the Lease
regarding liens.

     3.     Work Cost.  "Work Cost" means:  (a) all design and engineering
            ---------
fees incurred in connection with the preparation and review of the Space Plans
and Final Plans (including the cost of Lessor's consulting architect, engineers
and other consultants); (b) costs of permits, fees and taxes; (c) testing and
inspecting costs; (d) the actual costs and charges for

                                Exhibit "C"
                                Page 6 of 8
<PAGE>   106


material and labor, contractor's profit and contractor's general overhead
incurred by Lessee in having the Lessee Improvements done; (e) all other costs
expended in the construction of the Lessee Improvements, and (f) construction
management fee equal to 2.0% of the other Work Costs.

     4.     Nonliability of Reviewing Party.  Except as otherwise expressly
            -------------------------------
set forth in this Lease, the review by Lessor (the "Reviewer") of any plans
prepared by Lessee or any other party (the "Preparer") is for the Reviewer's
benefit only, and the Reviewer's approval of any such plans (a) shall not be
relied upon by the Preparer or by any other person or entity, (b) shall impose
no liability on the Reviewer, (c) shall not constitute a representation or
warranty by the Reviewer, express or implied, including without limitation any
representation or warranty that such plans are complete or accurate, or that
such plans comply with zoning or other land use laws, local building department
requirements, or any applicable public or private covenants, conditions or
restrictions, and (d) shall not in any way relieve the Preparer of its
obligation to prepare its plans and perform its work in accordance with this
Lease and all applicable laws and requirements.

     5.     Delays.  The Commencement Date shall be extended (i) one (1) day
            ------
for each day that Lessee is actually and directly delayed in substantially
completing the Lessee Improvements (excluding decoration and punch-list items)
because of "Lessor Delays", as such term is defined below.  As used herein, the
term "Lessor Delay" shall mean any delay in substantial completion of the
Lessee Improvements which is actually and directly caused by all or any of the
following:


        (1)     Lessor's failure to respond to any request for approved of the
Space Plans or Plans within the time periods established in this Work Letter
Agreement;

        (2)     Lessor's failure to provide Lessee or Lessee's contractors
complete access to the Premises;

        (3)     Lessor's failure to fund Lessor's share of the Work Costs up
to, but not exceeding, the Allowance, in accordance with the terms of Paragraph
3.4 above; and

        (4)     any other act or failure to act by Lessor, its agents or
contractors which actually and directly delays the substantial completion of
the Lessee Improvements.

                                Exhibit "C"
                                Page 7 of 8
<PAGE>   107


          No Lessor Delay shall be deemed to occur unless and until Lessee
provides written notice to Lessor, in compliance with the notice provisions of
the Lease, claiming that such delay(s) occurred and specifying in detail or
inaction on the part of Lessor which is the basis for such claim.  If such
action or inaction is not cured by Lessor by the date which is one (1) business
day after Lessor's receipt of such notice (the "Cure Date"), then unless Lessor
proves that such action or inaction did not actually cause a delay in
substantial completion of the Lessee Improvements, the Lessor Delay as set
forth in such notice shall be deemed to have occurred commencing as of the date
after the Cure Day and continuing for the number of days the inaction or action
claimed by Lessee in such notice remains uncured and actually and directly
causes a delay in substantial completion of the Lessee Improvements beyond such
date.

                               PROMISSORY NOTE



$1,087,500.00                                      Los Angeles, California
                                                           October 7, 1999


          FOR VALUE RECEIVED, the undersigned, FUSION MEDICAL TECHNOLOGIES,
INC., a Delaware corporation ("Maker"), having an address at 34175 Ardenwood
Boulevard, Fremont, California,  PROMISES TO PAY TO THE ORDER OF TARLTON/WOHL
VENTURE NINE LLC ("Landlord") (Landlord and its successors and assigns who
become holders of this Promissory Note (the "Note") are hereinafter
collectively referred to as "Holder"), to Landlord at c/o Tarlton Properties,
Inc., 955 Alma Street, Palo Alto, California  94301, or at such other place as
Holder, may from time to time designate, the principal sum of One Million
Eighty-Seven Thousand Five Hundred and No/100ths Dollars ($1,087,500.00), or so
much thereof as may have been advanced pursuant hereto and to the Lease (as
defined below), together with interest thereon from the date funds are first
disbursed hereunder until paid at a rate per annum equal to the Interest Rate
(as hereinafter defined).  Interest shall be calculated on the basis of a 360-
day year and 30-day month; except with respect to partial months in which case
interest shall be calculated on the basis of the actual number of days in the
year and the actual number of days elapsed in the period during which it
accrues, in accordance with the terms and conditions set forth below.

     1.     Definitions.  For the purpose of this Note, the following terms
     ------------------
shall have the meanings set forth below; certain other terms are defined where
they appear in this Note:

        (1)     "Interest Rate" means a rate of interest per annum of nine
                 -------------
and one-half percent (9.5%).

        (2)     "Lease" means that certain Lease dated October 7, 1999,
                 -----
entered into by and between Landlord as "Lessor" and Maker as "Lessee" of
certain premises commonly known as 34175 Ardenwood Boulevard, Fremont,
California.

        (3)     "Loan" means the loan evidenced by this Note.
                 ----

        (4)     "Maturity Date" means December 1, 2006.
                 -------------

(5)     "Principal Balance" means the outstanding principal balance of this
         -----------------
Note from time to time outstanding.

                                    -1-
<PAGE>   109

        (6)     "Secondary Interest Rate" means a rate of interest equal to
                 -----------------------
the greater of (i) eighteen percent (18%) per annum, or (ii) a per annum rate
equal to five percent (5%) over the prime rate (for corporate loans at large
United States money center commercial banks) published in the Wall Street
Journal on the first business day of each month in which such default occurs or
continues.

     2.     Payments.  Commencing on the Commencement Date (as defined in
            --------
the Lease) and continuing on the first day of each calendar month thereafter
through and including the first day of December, 2006, monthly installments of
principal and interest in the amount of $17,774.08 each shall be due and
payable with the entire unpaid Principal Balance plus accrued interest and
other amounts payable under this Note being due and payable on the Maturity
Date.

     3.     Treatment of Payments.  All payments due under this Note shall
            ---------------------
be paid by Maker in lawful money of the United States of America on the date
such payment is due.  All such payments shall be made without deduction for any
present or future taxes, levies, imposts, deductions, charges or withholdings
(including U.S., state or local income taxes), which amounts shall be paid by
Maker.  Payments from Maker to Holder under this Note shall be applied first to
the payment of any Per Diem Late Charges or Late Charges (each as hereinafter
defined), in such order as Holder shall determine, then to accrued and unpaid
interest, with the remainder to be applied to the Principal Balance.

     4.     Per Diem Late Charges, Late Charges and Secondary Interest.
            ----------------------------------------------------------

        (1)     If Maker fails timely to pay any sum due and payable under this
Note on or before the date due, a late charge equal to One Hundred Dollars
($100) per day (the "Per Diem Late Charge") shall be assessed for each day that
such payment is not paid from and including the first day following the date
such payment was due to and including the date upon which such payment is made;
provided, however, that notwithstanding the foregoing, if such payment,
together with all accrued Per Diem Late Charges, is not made on or before the
tenth (10th) day following the date due, a late charge equal to four cents
($.04) for each dollar ($1.00) of each such late payment (the "Late Charge")
shall be immediately due and payable.  The Late Charge shall be in lieu of the
Per Diem Late Charges that shall have accrued during the immediately preceding
ten (10) day period.  Maker acknowledges and agrees that its failure to make
timely payments will result in Holder incurring additional expense in servicing
the Loan, and that it is extremely difficult and impractical to ascertain the
extent of such damages and that the Per Diem Late Charges and the Late Charge
represent fair and reasonable estimates, considering all of the circumstances
existing on the date of the execution of this Note, of the costs that Holder
will incur by reason of such late payment.  Acceptance of any Per Diem Late
Charge or Late Charge shall not constitute a waiver of the default with respect
to the late payment, and shall not prevent Holder from exercising any of the
other rights or remedies available hereunder or at law or in equity.

                                    -2-
<PAGE>   110

        (2)     Maker further acknowledges and agrees that during the time that
any payment of principal, interest or other amount due under this Note shall be
delinquent, Holder will incur additional costs and expenses attributable to its
loss of use of money due to and to the adverse impact on Holder's ability to
meet its other obligations and avail itself of other opportunities.  Maker
agrees that it is extremely difficult and impractical to ascertain the extent
of such expenses, and Maker therefore agrees that interest at the Secondary
Interest Rate shall accrue on any delinquent payments of principal, interest or
other amounts due under this Note or any Loan Document from the date such
payments were due and for so long as non-payment continues, regardless of
whether or not there has been an acceleration of the maturity of the
indebtedness evidenced by this Note.

     5.     Event of Default and Secondary Interest.
            ---------------------------------------

        (1)     Maker's failure to pay any sum due and payable under this Note
on or before the due date therefor which is not cured within 5 days after
written notice thereof from Holder to Maker shall be an Event of Default under
this Note.  The occurrence of a default under the Lease shall also constitute
an Event of Default under this Note.

        (2)     It shall constitute an Event of Default hereunder without the
requirement of any notice if one or more of the following events shall have
occurred and be continuing:

          (1)     (i) The entry of an order for relief under Title 11 of the
United States Code as to Maker or the adjudication of Maker as insolvent or
bankrupt pursuant to the provisions of any state insolvency or bankruptcy act;
(ii) the commencement by Maker of any case, proceeding or other action seeking
any reorganization, arrangement, composition, adjustment, liquidation,
dissolution or similar relief for itself under any present or future statute,
law or regulation relating to bankruptcy, insolvency, reorganization or other
relief for debtors; (iii) consent to, acquiescence in or attempt to secure the
appointment of any receiver of all or any substantial part of its properties by
Maker; (iv) Maker shall generally not pay its debts as they become due or shall
admit in writing its inability to pay its debts or shall make a general
assignment for the benefit of creditors; or (v) Maker shall take any action to
authorize any of the acts set forth above; or

          (2)     Any case, proceeding or other action against Maker shall be
commenced seeking to have an order for relief entered against such party as a
debtor or seeking any reorganization, arrangement, composition, adjustment,
liquidation, dissolution or similar relief for itself under any present or
future statute, law or regulation relating to bankruptcy, insolvency,
reorganization or other relief for debtors, or seeking the appointment of any
receiver for Maker or for all or any substantial part of its property, and such
case, proceeding or other action remains undismissed for an aggregate of sixty
(60) days (whether or not consecutive) or Maker fails to proceed diligently
during such sixty (60) day period to have such proceeding or other action
dismissed.

        (3)     Upon the occurrence of an Event of Default, Holder, may at any
time

                                  -3-
<PAGE>   111

declare the Principal Balance together with all unpaid accrued interest, and
any other sums evidenced by this Note, to be immediately due and payable,
without further presentment, demand, protest or notice of any kind.

        (4)     Maker agrees that from and after the acceleration of the
indebtedness pursuant to Paragraph 5(c) hereof, interest at the Secondary
Interest Rate shall accrue on the Principal Balance and all unpaid accrued
interest and other sums evidenced by this Note.

     6.     Prepayment.  Maker shall not have the right to prepay all or any
            ----------
portion of the Principal Balance.

     7.     Letter of Credit.  Upon the occurrence of an Event of Default,
            ----------------
Holder may draw on the Letter of Credit ("Letter of Credit") described in the
Lease and apply the amount so drawn to the payment of principal in the inverse
order of maturity, interest and other accounts due under this Note.  No such
draw and application of funds from the letter of Credit shall be deemed to cure
an Event of Default unless (a) the draw causes the Principal Balance and all
accrued interest thereon to be paid in full, (b) the remaining undrawn amount
under the Letter of Credit is equal to or greater than the then outstanding
Principal Balance and accrued interest under this Note, or (c) within 5 days
after the draw Maker restores the undrawn amount of the Letter of Credit to the
amount that existed prior to the draw.

     8.     Holder's Rights; No Waiver by Holder.  The rights, powers and
            ------------------------------------
remedies of Holder under this Note shall be in addition to all rights, powers
and remedies given to Holder under the Lease or by virtue of any statute or
rule of law, including, but not limited to, the California Uniform Commercial
Code.  All such rights, powers and remedies shall be cumulative and may be
exercised successively or concurrently in Holder's sole discretion without
impairing Holder's rights or available remedies.  Any forbearance, failure or
delay by Holder in exercising any right, power or remedy shall not preclude
further exercise thereof, and every right, power or remedy of Holder shall
continue in full force and effect until such right, power or remedy is
specifically waived in a writing executed by Holder.  Maker waives any right to
require the Holder to proceed against any person or to pursue any remedy in
Holder's power.

     9.     Maker's Waivers.
            ---------------

        (1)     Maker and any endorsers of this Note, and each of them, hereby
waive diligence, demand, presentment for payment, notice of non-payment,
protest and notice of protest, and specifically consent to and waive notice of
any renewals or extensions of this Note, whether made to or in favor of Maker
or any person or persons.  Maker and any endorsers of this Note expressly waive
all right to the benefit of any statute of limitations and any moratorium,
reinstatement, marshalling, forbearance, extension, redemption, or appraisement
now or hereafter provided by the Constitution or the laws of the United States
or of any state thereof, as a defense to any demand against Maker or any such
endorsers, to the fullest extent permitted by law.

                                    -4-
<PAGE>   112

        (2)     Maker hereby waives any right to trial by jury with respect to
any action or proceeding brought by Maker, Holder or any other person relating
to the indebtedness evidenced by this Note.  Maker hereby agrees that this Note
constitutes a written consent to waiver of trial by jury pursuant to the
provisions of California Code of Civil Procedure Section 631 and Maker does
hereby constitute and appoint Holder its true and lawful attorney-in-fact,
which appointment is coupled with an interest, and Maker does hereby authorize
and empower Holder, in the name, place and stead of Maker, to file this Note
with the clerk or judge of any court of competent jurisdiction as statutory
written consent to waiver of trial by jury.

     10.     Transfers by Holder.  This Note or any interest in this Note
             -------------------
may be hypothecated, transferred or assigned by Holder without the prior
consent of Maker to any successor landlord under the Lease.

     11.     Amendment.  This Note may be amended or modified only by an
             ---------
