              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (Unaudited)

A.  ACCOUNTING POLICIES

BASIS OF PRESENTATION

     The condensed consolidated financial statements include the accounts of PRI
Automation, Inc., its wholly-owned domestic subsidiaries and its wholly-owned
and majority-owned foreign subsidiaries (collectively, the "Company"). All
significant intercompany transactions and balances have been eliminated.

     In March 1999, the Company acquired Promis Systems Corporation Ltd.
("Promis"). The acquisition of Promis was accounted for using the
pooling-of-interests method of accounting. All prior period historical condensed
consolidated financial statements presented herein have been restated to include
the financial position, results of operations, and cash flows of Promis.

PREPARATION OF FINANCIAL STATEMENTS

     The interim financial data as of January 2, 2000 and for the three months
ended January 2, 2000 and December 27, 1998 is unaudited; however, in the
opinion of the Company, the interim data includes all adjustments, consisting
only of normal recurring adjustments, necessary for a fair statement of the
results for the interim periods. The results for interim periods are not
necessarily indicative of the results for the entire year. The condensed
consolidated financial statements should be read in connection with the audited
consolidated financial statements of PRI Automation, Inc. for the year ended
September 30, 1999 included in its Annual Report on Form 10-K filed with the
Securities and Exchange Commission.

     For interim reporting purposes, the Company closes its first three fiscal
quarters on the Sunday nearest the last day of December, March and June in each
year. The Company's fiscal year ends on the last day of September.

D.  NET INCOME (LOSS) PER SHARE

     Basic net income (loss) per common share is computed based on the weighted
average number of common shares outstanding during the period. Diluted net
income (loss) per common share gives effect to all dilutive potential common
shares outstanding during the period. A reconciliation between basic and diluted
net income (loss) per share is as follows (in thousands, except per share data):

         Diluted net income (loss) per share......................           $  0.01              $ (0.36)
</TABLE>

     Options to purchase 768,150 shares of common stock were outstanding as of
January 2, 2000 but were not included in the computation of diluted net income
per common share because the options' exercise prices were greater than the
average market price of the common shares, and therefore, would be anti-dilutive
under the treasury stock method. Options to purchase 3,391,906 shares of common
stock were outstanding as of December 27, 1998, but were not included in the
computation of diluted net loss per common share because the Company was in a
loss position, and the inclusion of such shares would be anti-dilutive.

E.  OTHER COMPREHENSIVE INCOME

     The Company previously adopted SFAS No. 130, "Reporting Comprehensive
Income," which established standards for reporting and displaying comprehensive
income and its components in a financial statement that is displayed with the
same prominence as other financial statements. Comprehensive income (loss) is
equal to net income (loss) for the three months ended January 2, 2000 and
December 27, 1998.

F.  ACQUISITION OF PROMIS

     On March 2, 1999, the Company acquired Promis, a Canadian corporation, in a
transaction accounted for as a pooling of interests. Promis was a developer of
manufacturing execution systems ("MES") software solutions for semiconductor and
precision electronics manufacturers. In connection with the acquisition, the
Company issued 0.1353 exchangeable shares for each outstanding Promis share, or
an aggregate of 1,389,974 exchangeable shares. Each exchangeable share may be
exchanged at any time for one share of common stock of the Company. The Company
assumed options to purchase 270,336 shares of the Company's common stock and a
warrant to purchase 13,530 shares of common stock, converted at the common stock
exchange ratio, under this acquisition agreement. The consolidated financial
statements of the Company for periods prior to the acquisition have been
restated to include the financial position, results of operations and cash flows
of Promis.

G.  SPECIAL CHARGES

     During the quarter ended March 28, 1999, the Company recorded special
charges of $1,850,000. The special charges consisted of $1,406,000 for
compensation-related costs for five management employees in the selling, general
and administrative functions to satisfy existing contractual obligations related
to the acquired companies; $196,000 of costs associated with the reductions of
leased facilities; and $248,000 for other legal issues. At January 2, 2000,
$272,000 of these charges remained in accrued expenses and are expected to be
paid by the end of calendar year 2000.

     During the quarter ended December 27, 1998, the Company recorded special
charges of $650,000. These charges represent provisions for employee severance
compensation relating to the termination of 62 employees and consultants. These
headcount reductions were approximately 40 in manufacturing and customer
support, 8 in engineering, and 14 in selling, general and administrative
functions. The reduction in force occurred in response to the continued downturn
in the semiconductor equipment industry. All of these special charges have been
paid.

H.  INCOME TAXES

     The income tax provision for the three months ended January 2, 2000 was
$110,000, or 27.2% of income before income taxes, compared to a benefit of
$2,949,000, or 27.8% of loss before income taxes, for the three months ended
December 27, 1998. The tax provision of $110,000 is primarily related to foreign
and state taxes. During the third quarter of fiscal year 1999, management
concluded that a full valuation allowance against the Company's net deferred tax
assets was required, under applicable accounting standards, due to uncertainties
surrounding their realization. Accordingly a valuation allowance in an amount
equal to the net deferred tax assets was established to reflect these
uncertainties. The effective tax rate for the three months ended December 27,
1998 differed from the statutory rate primarily because income of certain
foreign subsidiaries was not subject to income tax due to available tax credits
and net operating losses.

I.  SEGMENT REPORTING

     The Company operates in three primary segments, all within the
semiconductor manufacturing and OEM equipment supply industry, which serve both
domestic and international markets. These reportable operating segments consist
of Factory Automation Systems, Tool Automation Systems and MES and Other
Systems. The MES and Other Systems segment


                                       8
<PAGE>

includes factory management software and advanced planning and scheduling
software product lines. The Company's operating segments have no significant
intersegment revenues and expenses, as all segments' revenues are generated
from sales to unaffiliated customers.

     Operating segment information for the three months ended January 2, 2000
and December 27, 1998 is as follows:

J.  CONTINGENT LIABILITY

     At January 2, 2000, the Company had a contingent liability of approximately
$142,000. In 1993, Promis purchased the business assets and assumed selected
liabilities of Palette Systems, Inc., a Canadian company (the "sellers"). The
purchase price of approximately $9.9 million consisted of $5.5 million in cash
and 59,889 exchangeable common shares, as converted at the common stock exchange
ratio, of the Company, valued at $73.91 per common share. At the time of the
acquisition, Promis agreed that on April 7, 1998 it would pay additional cash
consideration to the sellers of an amount equal to the amount by which
approximately $4.0 million exceeded the market value of the common shares owned
by the sellers on April 7, 1998.

     On March 29, 1996, Promis made a formal claim against the sellers pursuant
to the dispute resolution provisions of the original purchase and sale
agreements. The sellers filed certain counterclaims against Promis. In 1997,
Promis and the sellers reached a settlement of the dispute. The settlement
provided that commencing on April 7, 1998 Promis would pay additional cash to
the sellers in an amount equal to the amount by which the market value of 59,889
exchangeable common shares, on each of the agreed-upon payment dates, is less
than $73.91 per common share. As part of the settlement, half the additional
cash consideration was payable on April 7, 1998, with the remaining half due in
20 quarterly installments commencing on July 7, 1998


                                       9
<PAGE>

through April 7, 2003. Under the terms of the settlement agreement, the sellers
are restricted as to the number of shares of the Company's common stock which
can be sold in any quarter prior to April 7, 2003.

     Since the payment of additional consideration is determined based on the
Company's share price at various future dates, any consideration in addition to
that paid to date will be recorded as a reduction in additional paid-in capital
of the Company as the amounts become determinable. The Company's contingent
liability as of January 2, 2000, calculated based on the market value of the
Company's common stock at January 2, 2000, is approximately $142,000.

K.  JOINT VENTURE

     The Company has entered into a joint venture with Shinsung Engineering Co.
Ltd. ("SEC") to distribute the Company's products and services in Korea. SEC is
in the business of developing and marketing products and services for the
semiconductor industry. The Company and SEC intend to invest on a pro rata basis
2.6 billion Korean won, or approximately $2.3 million, in the joint venture over
a two-year period through June 2000. As of January 2, 2000, the Company had
outstanding commitments under this agreement of 1.2 billion Korean won, or
approximately $1.0 million.

L.  RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. The statement requires companies to
recognize all derivatives as either assets or liabilities, with the instruments
measured at fair value. The accounting for changes in fair value, gains or
losses, depends on the intended use of the derivative and its resulting
designation. The statement is effective for all fiscal quarters of fiscal years
beginning after June 15, 2000. The Company will adopt SFAS No. 133 by fiscal
2001, in accordance with SFAS No. 137, which deferred the effective date of SFAS
No. 133. The Company is evaluating SFAS No. 133 to determine the impact on its
consolidated financial statements.

     In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial
Statements" ("SAB 101"). SAB 101 summarizes the staff's view in applying
generally accepted accounting principles to selected revenue recognition
issues. The application of the guidance in SAB 101 will be required in the
Company's first quarter of fiscal 2001. The effects of applying this guidance
will be reported as a cumulative effect adjustment resulting from a change in
accounting principle. The Company does not expect the application to have a
material effect on its financial statements; however, the final evaluation of
SAB 101 is not yet complete.

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

CERTAIN FACTORS THAT MAY AFFECT FUTURE RESULTS

     From time to time, information provided by the Company, statements made by
its employees or information included in its filings with the Securities and
Exchange Commission may contain statements which are not historical facts but
which are "forward-looking statements" involving risks and uncertainties. In
particular, statements in "Management's Discussion and Analysis of Financial
Condition and Results of Operations" relating to the Company's shipment level
and profitability and the sufficiency of capital to meet working capital and
capital expenditure requirements may be forward-looking statements. The words
"expect," "anticipate," "internal," "plan," "believe," "seek," "estimate" and
similar expressions are intended to identify such forward-looking statements.
This Report also contains other forward-looking statements. Such statements are
not guarantees of future performance and involve certain risks, uncertainties
and assumptions that could cause the Company's future results to differ
materially from those expressed in any forward-looking statements made by or on
behalf of the Company. Many of these factors are beyond the Company's ability to
control or predict. Readers are accordingly cautioned not to place undue
reliance on forward-looking statements. The Company disclaims any intent or
obligation to update publicly any forward-looking statements, whether in
response to new information or future events or otherwise. Important factors
that may cause the Company's actual results to differ from such forward-looking
statements include, but are not limited to, the factors discussed below.

     The Company's future results are subject to substantial risks and
uncertainties. The Company's business and results of operations depend in
significant part upon capital expenditures of manufacturers of semiconductors,
which in turn depend upon the current and anticipated market demand for
semiconductors and products incorporating semiconductors. Historically, the
semiconductor industry has been highly cyclical with recurring periods of
over-supply. This recurring over-supply often has had a severe effect on the
semiconductor industry's demand for capital equipment, including systems
manufactured and marketed by the Company. Oversupply in the semiconductor market
may in the future reduce demand for capital equipment, including demand for the
Company's systems. The semiconductor industry recently experienced a downturn
that adversely affected the Company's operating results, and reduced demand for
semiconductors in the future could jeopardize the Company's plans. The Company
believes that the markets for newer generations of semiconductors will be
subject to similar fluctuations. Also, the recent high rate of technical
innovation and resulting improvements in the performance and price of
semiconductor devices, which have driven much of the demand for the Company's
products, could slow, or encounter limits, in the future. In addition, any other
factor adversely affecting the semiconductor industry or particular segments
within the semiconductor industry may adversely effect the Company's business,
financial condition and operating results.

     In addition to the risks and uncertainties posed generally by the
cyclicality of the semiconductor industry, the Company faces the following
risks and uncertainties: the Company's lengthy sales cycle makes it difficult
to anticipate sales; the Company's operating results fluctuate significantly
and the Company's stock price could fall if its operating results are below
expectations of analysts or investors; delay in shipment of a single system
could substantially decrease the Company's sales for the period in which the
delay occurs; the Company typically charges a fixed price for a system which
allows for vulnerability to cost overruns; the Company has significant fixed
costs which are not easily reduced during a downturn; the Company depends on
a limited number of customers and the loss, cancellation or delay of any
order by these customers could adversely affect the Company's results; the
Company's customers do not have long-term purchase agreements with the
Company, and as a result, customers could stop purchasing the Company's

                                       11
<PAGE>

products and services at any time; industry consolidation and outsourcing of
the manufacture of semiconductors to foundries could reduce the number of
available customers; the Company's ongoing efforts to compete in the
Asia-Pacific market may not be successful; the Company has invested heavily
in 300mm wafer technology, which is being adopted more slowly than the
Company expected; the Company needs managerial and technical employees who
because of their skills and experience may be difficult to hire and retain;
the Company may have difficulty managing growth in light of fluctuating
demand; the Company's substantial international operations create special
risks; the Company faces significant competition from other automation
companies which may limit the prices it can charge for its products and may
result in lost sales; in order to continually improve its technology to
remain competitive, the Company must expend substantial resources on research
and development, even in periods during industry downturns; the Company may
experience delays in product development and technical difficulties that
could delay new product introductions; future acquisitions may disrupt the
Company's operations; the Company depends on subcontractors and one or a few
suppliers for some components and manufacturing processes; the Company
depends on Mitchell G. Tyson, its President and Chief Executive Officer, and
other senior staff; the Company's Chief Financial Officer has resigned and it
may not be able to replace him in a timely manner; the Company's software
products may contain errors or defects that could result in lost revenue,
delayed or limited market acceptance or product liability claims with
substantial litigation costs; the Company may be unable to protect its
proprietary technology; claims by others that the Company infringes their
proprietary technology could harm the Company's business; Year 2000 problems
may disrupt the Company's operations; the market price of the Company's
common stock is volatile; the Company may need additional financing which
could be difficult to obtain; and certain provisions of the Company's charter
and by-laws and Massachusetts law make a takeover of the Company more
difficult. As a result of the foregoing and other factors, the Company may
experience material fluctuations in its future operating results on a
quarterly or annual basis which could materially adversely affect its
business, financial condition, operating results and stock price.

RESULTS OF OPERATIONS

     On March 2, 1999, the Company acquired Promis Systems Corporation Ltd., a
Canadian corporation ("Promis"). Promis was a leading developer of manufacturing
execution systems ("MES") software solutions for semiconductor and precision
electronics manufacturers. The business combination was accounted for as a
pooling of interests; accordingly, the financial results of the Company for
fiscal 1999 have been restated to include Promis.

     TOTAL NET REVENUE: Total net revenue for the fiscal quarter ended
January 2, 2000 increased 98.1% to $58.7 million, compared to $29.6 million
for the corresponding period in fiscal 1999. This represents the fourth
consecutive quarter of revenue growth. The growth was experienced across all
of the Company's operating segments. Most of the increase was related to
product and equipment revenue, which increased 137.3%, while services and
maintenance revenue increased 6.9% from the corresponding period in fiscal
1999. The increase in net revenue is due to the growth in requirements for
capital equipment within the semiconductor industry arising from the increase
in demand for semiconductor-related products. Net export sales to European
and Asian customers for the fiscal quarter ended January 2, 2000 were $24.8
million, or 42.3% of total net revenue, compared to $5.9 million, or 20.0% of
total net revenue for the corresponding period in fiscal 1999. Sales to
foreign customers are denominated in U.S. dollars with the exception of
certain sales of tool automation and spare parts products which are
denominated in local currencies.

                                       12
<PAGE>

     GROSS PROFIT: The gross profit margin was 36.4% for the fiscal quarter
ended January 2, 2000, compared to 32.0% for the corresponding period in
fiscal 1999. The increase in gross profit margin was primarily experienced by
the Factory Systems and Tool Automation Systems segments. The increase in the
gross profit margin is due to a number of factors including a change in
product mix with a more significant increase in product and equipment revenue
as compared to service and maintenance revenue. Additionally, the upturn in
industry demand has improved product pricing and the growth in
production volume has increased manufacturing efficiencies and improved
related costs. At the same time, the gross profit margin was adversely
impacted by costs related to the introduction of new products.

     RESEARCH AND DEVELOPMENT: Research and development expenses increased to
$12.2 million, or 20.7% of total net revenue, for the fiscal quarter ended
January 2, 2000, compared to $10.4 million, or 35.1% of total net revenue, for
the corresponding quarter in fiscal 1999. The increase in spending reflects the
Company's continued investment in new product development and enhancements of
existing product lines. The Company continued to invest in the development of
200mm and 300mm products throughout its factory automation and tool automation
product lines, as well as the manufacturing execution and advanced planning and
scheduling software product lines. Research and development expenses decreased
as a percentage of total net revenue for the fiscal quarter ended January 2,
2000, compared with the corresponding period in fiscal 1999, due to the increase
in revenues.

     SELLING, GENERAL AND ADMINISTRATIVE: Selling, general and administrative
expenses decreased to $9.0 million, or 15.4% of total net revenue, for the
fiscal quarter ended January 2, 2000, compared to $9.7 million, or 32.7% of
total net revenue, for the corresponding period in fiscal 1999. The decrease in
the dollar amount of selling, general and administrative expenses for the first
quarter of fiscal 2000 is primarily attributable to the consolidation of
duplicate functions and activities of acquired companies.

     SPECIAL CHARGES: The Company did not incur special charges for the
fiscal quarter ended January 2, 2000. However, at January 2, 2000, $272,000 of
previously incurred special charges remained in accrued expenses. During the
quarter ended March 28, 1999, the Company recorded special charges of $1.9
million. The special charges consisted of $1.4 million for
compensation-related costs for five management employees in the selling,
general and administrative functions to satisfy existing contractual
obligations related to the acquired companies; $196,000 of costs associated
with the reductions of leased facilities; and $248,000 for other legal
issues. The remaining $272,000 of these special charges are expected to be
paid by the end of calendar year 2000.

     During the first fiscal quarter of 1999, the Company recorded special
charges of $650,000 representing provisions for employee severance compensation
relating to the termination of 62 employees and consultants. The headcount
reductions included 40 in manufacturing and customer support, 8 in engineering,
and 14 in selling, general and administrative functions. The reduction in force
occurred in response to the downturn in the semiconductor equipment industry.
All of these special charges have been paid.

     OPERATING PROFIT (LOSS): As a result of the increase in total net revenue
and the other foregoing factors, the operating profit for the fiscal quarter
ended January 2, 2000 was $204,000, or 0.3% of total net revenue, compared to an
operating loss of $11.3 million, or 38.0% of total net revenue, for the
corresponding quarter in fiscal 1999. Excluding the special charges of $650,000,
the operating loss in the first fiscal quarter of 1999 would have been $10.6
million, or 35.8% of net revenue.


                                       13
<PAGE>

     OTHER INCOME, NET: Other income, net for the fiscal quarter ended January
2, 2000 was $200,000, compared to $656,000 for the corresponding quarter in
fiscal year 1999. Interest income for the fiscal quarter ended January 2, 2000
was $537,000, compared to $548,000 for the corresponding quarter in fiscal 1999.
Interest expense for the current quarter was $20,000, compared to $32,000 for
the prior quarter in fiscal 1999. Net translation and foreign exchange losses
for the current fiscal quarter was $241,000, compared to net translation and
foreign exchange gains of $198,000 in the corresponding quarter in fiscal 1999.

     PROVISION FOR (BENEFIT FROM) INCOME TAXES: The income tax provision for the
three months ended January 2, 2000 was $110,000, or 27.2% of income before
income taxes, compared to a benefit of $2.9 million, or 27.8% of loss before
income taxes, for the three months ended December 27, 1998. The tax provision of
$110,000 is primarily related to foreign and state taxes. During the third
quarter of fiscal year 1999, management concluded that a full valuation
allowance against the Company's net deferred tax assets was required, under
applicable accounting standards, due to uncertainties surrounding their
realization. Accordingly a valuation allowance in an amount equal to the net
deferred tax assets was established to reflect these uncertainties. The
effective tax rate for the three months ended December 27, 1998 differed from
the statutory rate primarily because income of certain foreign subsidiaries was
not subject to income tax due to available tax credits and net operating losses.

     NET INCOME (LOSS): Net income for the fiscal quarter ended January 2, 2000
was $294,000, compared to the net loss of $7.7 million for the corresponding
quarter in fiscal 1999. Excluding the special charges net of their tax effect,
the net loss for the first quarter of fiscal 1999 would have been $7.2 million.

LIQUIDITY AND CAPITAL RESOURCES

     The Company has funded its operations primarily through public stock
offerings in October 1994 and July 1995, cash generated from operations and bank
lines of credit. As of January 2, 2000, the Company had working capital of $87.3
million, including cash and cash equivalents of $45.2 million, compared to
working capital of $78.9 million and cash and cash equivalents of $51.9 million
as of September 30, 1999.

     Net cash used in operating activities was $11.8 million for the three
months ended January 2, 2000, compared to $6.7 million for the corresponding
period in fiscal 1999. The net cash used in operations in the first quarter of
fiscal 2000 was primarily attributable to increases in contracts in progress of
$11.8 million and increases in accounts receivable of $6.0 million. These
increases are related to the significant growth in total net revenue in the
first quarter of fiscal 2000. These cash outflows were slightly offset by
proceeds associated with the decrease in other assets, which is primarily the
result of a $5.0 million income tax refund received in the first quarter of
fiscal 2000. Net cash used in operations for the three months ended December 27,
1998 was primarily attributable to the $7.7 million net loss. Additionally, a
decrease in accounts payable used $5.1 million of net cash. This outflow was
partially offset by proceeds related to decreases in inventories of $4.7 million
and increases in accrued expenses of $1.9 million.

     Net cash used in investing activities was $2.4 million for the three months
ended January 2, 2000, compared to $1.4 million for the corresponding period in
fiscal 1999. The increase in investing activities is primarily due to an
additional $1.2 million of property and equipment purchases made in the first
quarter of fiscal 2000 as compared with the corresponding period in fiscal 1999.

     Net cash provided by financing activities was $7.9 million for the three
months ended January 2, 2000, compared to $825,000 for the corresponding period
in fiscal 1999. The net cash


                                       14
<PAGE>

provided by financing activities for each of these fiscal periods was primarily
attributable to proceeds from the exercise of stock options and the Company's
Employee Stock Purchase Plan.

     At January 2, 2000, the Company had a revolving credit facility
agreement with Chase Manhattan Bank (the "Bank"). The revolving credit
facility enables the Company to borrow up to $20,000,000 on an unsecured
basis. Outstanding revolving credit loans bear interest, at the Company's
option, at the 30-, 60-or 90-day LIBOR rate plus a credit spread or at the
effective prime rate. At January 2, 2000, the Company's borrowing rate would
have been 7.0%. The ability of the Company to borrow under the revolving
credit facility is conditioned upon meeting certain financial criteria. The
revolving credit agreement expires on June 16, 2000. The Company had
outstanding letters of credit with the Bank in the aggregate amount of
$1,420,000 at January 2, 2000, and therefore, the available balance under
this credit agreement was $18,580,000 at January 2, 2000. At January 2, 2000,
the Company was not in compliance with certain of the required covenants but
has subsequently obtained a waiver from the Bank, through January 2, 2000, on
January 25, 2000. The Company was in default of the minimum consolidated net
worth requirement, the minimum fixed charge coverage ratio and the minimum
consolidated net income requirements of the revolving credit agreement for
the fiscal quarter ended January 2, 2000. The Company expects to seek future
waivers as necessary from the Bank. However, there can be no assurance that
such waivers will be obtained.

     The Company believes its existing cash balances and funds available
under its existing revolving credit facility will be sufficient to meet the
Company's cash requirements to fund operations and expected capital
expenditures during the next twelve months. However, there can be no
assurance that additional financing, if needed, will be available or at terms
acceptable to the Company.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities." This statement establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. The statement requires companies to
recognize all derivatives as either assets or liabilities, with the instruments
measured at fair value. The accounting for changes in fair value, gains or
losses, depends on the intended use of the derivative and its resulting
designation. The statement is effective for all fiscal quarters of fiscal years
beginning after June 15, 2000. The Company will adopt SFAS No. 133 by fiscal
2001, in accordance with SFAS No. 137, which deferred the effective date of SFAS
No. 133. The Company is evaluating SFAS No. 133 to determine the impact on its
consolidated financial statements.

     In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101, "Revenue Recognition in Financial
Statements" ("SAB 101"). SAB 101 summarizes the staff's view in applying
generally accepted accounting principles to selected revenue recognition
issues. The application of the guidance in SAB 101 will be required in the
Company's first quarter of fiscal 2001. The effects of applying this guidance
will be reported as a cumulative effect adjustment resulting from a change in
accounting principle. The Company does not expect the application to have a
material effect on its financial statements; however, the final evaluation of
SAB 101 is not yet complete.

YEAR 2000

     Before January 1, 2000, it was generally expected that many computer
systems and software products would experience problems handling dates beyond
the year 1999 because the systems were coded to accept only two-digit entries in
the date code fields. Before December 31, 1999, the Company completed a
company-wide Year 2000 Project (the "Project") to minimize the impact of Year
2000 issues on the Company's business, including its products, services,
infrastructure, and internal business support applications. As of February 11,
2000, the Company


                                       15
<PAGE>

is not aware that any of its products or any of the products or systems on which
it relies have been unable to process dates accurately. It may be too early to
conclude that Year 2000 issues will not affect the Company's business, and the
inability of its products, or of products and systems on which it relies, to
process these dates accurately could have a material adverse effect on its
business.

     The risk posed by Year 2000 issues depends substantially on the number and
type of any instances of non-compliance that the Company has not yet discovered.
To the extent that the Company's internal systems, or products and services
obtained from third parties, are not Year 2000 compliant, the Company could face
disruptions in its business which could, in turn, cause delays in meeting
production and shipping goals and could divert significant management resources.

     To minimize potential disruptions, the Company has implemented a
contingency plan to address any unresolved issues affecting Year 2000
compliance, if needed. The Company's contingency plan identifies actions such as
disaster recovery, emergency notification systems, employee staffing,
suitability of alternate suppliers, and critical data backups in the key areas
of manufacturing and services, supply chain management, marketing, sales and
customer support, facilities, finance, legal and human resources.

     Based on its investigation to date, the Company does not expect the total
cost of its Year 2000 Project to have a material adverse effect on the Company's
business or financial results. The estimated total cost of the Year 2000 Project
is approximately $400,000. Substantially all of these costs have been expended
as of January 2, 2000.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

     There have been no significant changes in the Company's market risks since
the year ended September 30, 1999. For more information please read the
consolidated financial statements and notes thereto included in the Company's

applied. "Operating Expenses" shall mean all expenses and costs of every kind
and nature which Landlord shall pay or become obligated to pay, because of or in
connection with the ownership, management, maintenance, repair, preservation,
replacement and operation of the Building or Project and its supporting
facilities and such additional facilities now and in subsequent years as may be
determined by Landlord to be necessary or desirable to the Building and/or
Project (as determined in a reasonable manner) other than those expenses and
costs which are specifically attributable to Tenant or which are expressly made
the financial responsibility of Landlord or specific tenants of the Building or
Project pursuant to this Lease. Operating Expenses shall include, but are not
limited to, the following:

         (1) TAXES. All real property taxes and assessments, possessory interest
         taxes, sales taxes, personal property taxes, business or license taxes
         or fees, gross receipts taxes, service payments in lieu of such taxes
         or fees, annual or periodic license or use fees, excises, transit
         charges, and other impositions, general and special, ordinary and
         extraordinary, unforeseen as well as foreseen, of any kind (including
         fees "in-lieu" of any such tax or assessment) which are now or
         hereafter assessed, levied, charged, confirmed, or imposed by any
         public authority upon the Building or Project, its operations or the
         Rent (or any portion or component thereof), or any tax,: assessment or
         fee imposed in substitution, partially or totally, of any of the above.
         Operating Expenses shall also include any taxes, assessments,

         development, leasing, management, maintenance, alteration, repair, use
         or occupancy by Tenant of the Premises, Building or Project or any
         portion thereof, including, without limitation, by or for Tenant, and
         all increases therein or reassessments thereof whether the increases or
         reassessments result from increased rate and/or valuation (whether upon
         a transfer of the Building or Project or any portion thereof or any
         interest therein or for any other reason). Operating Expenses shall not
         include inheritance or estate taxes imposed upon or assessed against
         the interest of any person in the Project or taxes computed
<PAGE>

         upon the basis of the net income of any owners of any interest in the
         Project. If it shall not be lawful for Tenant to reimburse Landlord for
         all or any part of such taxes, the monthly rental payable to Landlord
         under this Lease shall be revised to net Landlord the same net rental
         after imposition of any such taxes by Landlord as would have been
         payable to Landlord prior to the payment of any such taxes.

         (2) INSURANCE. All insurance premiums and costs, including, but not
         limited to, any deductible amounts, premiums and other costs of
         insurance incurred by Landlord, including for the insurance coverage
         set forth in Paragraph 8.A. herein.

         financial responsibility of Landlord pursuant to Paragraph 10 hereof,
         those items to the extent paid for by the proceeds of insurance; and
         those items attributable solely or jointly to specific tenants of the
         Building or Project.

         (b) Repairs, replacements, and general maintenance shall include the
         cost of any capital improvements made to or capital assets acquired for
         the Project or Building that in Landlord's discretion may reduce any

         reasonably necessary for the health and safety of the occupants of the
         Building or Project, or are required to comply with any Regulation,
         such costs or allocable portions thereof to be amortized over the
         useful lives based on industry norms and Tenant shall be responsible
         for their pro rata share for the remaining Term of the Lease, together

         absence of such
<PAGE>

         prime rate, then at the U.S. Treasury six-month market note (or bond,
         if so designated) rate as published by any national financial
         publication selected by Landlord, plus four (4) percentage points, but
         in no event more than the maximum rate permitted by law, plus
         reasonable financing charges.

         (c) Payment under or for any casement, license, permit, operating
         agreement, declaration, restrictive covenant or instrument relating to
         the Building or Project.

         (e) The cost of supplying any services and utilities which benefit all

         addressed in Paragraph 15 hereof.

         (f) Legal expenses and the cost of audits by certified public
         accountants; provided, however, that legal expenses chargeable as
         Operating Expenses shall not include the cost of negotiating leases,
         collecting rents, evicting tenants nor shall it include costs incurred
         in legal proceedings with or against any tenant or to enforce the
         provisions of any lease.

         (g) A management and accounting cost recovery fee equal to Five percent
         (5%) of the sum of the Project's base rents and Operating Expenses
         (other than such management and accounting fee).

If the rentable area of the Building and/or Project is not fully occupied during
any fiscal year of the Term as determined by Landlord, an adjustment may be made
in Landlord's discretion in computing the Operating Expenses for such year so
that Tenant pays an equitable portion of all variable items (e.g., utilities,
janitorial services and other component expenses that are affected by variations
in occupancy levels) of Operating Expenses, as reasonably determined by
Landlord, provided, however, that in no event shall Landlord be entitled to
collect in excess of one hundred percent (100%) of the total Operating Expenses
from all of the tenants in the Building or Project, as the case may be.
<PAGE>

Operating Expenses shall not include the cost of providing tenant improvements
or other specific costs incurred for the account of, separately billed to and

Operating Expense also not include costs for any defects found in the HVAC,
roof, plumbing, electrical, or sprinkler systems not created by Tenant within
the first Ninety (90) days of the Lease term which Tenant notifies Landlord of
in writing and that Landlord should have reasonably known. Notwithstanding
anything herein to the contrary, in any instance wherein Landlord, in Landlord's
sole discretion, deems Tenant to be responsible for any amounts greater than
Tenant's Proportionate Share, Landlord shall have the right to allocate costs in
any manner Landlord deems appropriate.

The above enumeration of services and facilities shall not be deemed to impose
an obligation on Landlord to make available or provide such services or
facilities except to the extent if any that Landlord has specifically agreed
elsewhere in this Lease to make the same available or provide the same. Without
limiting the generality of the foregoing, Tenant acknowledges and agrees that it
shall be responsible for providing adequate security for its use of the
Premises, the Building and the Project and that Landlord shall have no
obligation or liability with respect thereto, except to the extent if any that
Landlord has specifically agreed elsewhere in this Lease to provide the same.

B. PAYMENT OF ESTIMATED OPERATING EXPENSES. "Estimated Operating Expenses" for
any particular year shall mean Landlord's estimate of the Operating Expenses for
such fiscal year made with respect to such fiscal year as hereinafter provided.
Landlord shall have the right from time to time to revise its fiscal year and
interim accounting periods so long as the periods as so revised are reconciled
with prior periods in a reasonable manner. During the last month of each fiscal
year during the Term, or as soon thereafter as practicable, Landlord shall give
Tenant written notice of the Estimated Operating Expenses for the ensuing fiscal
year. Tenant shall pay Tenant's Proportionate Share of the Estimated Operating
Expenses with installments of Base Rent for the fiscal year to which the
Estimated Operating Expenses applies in monthly installments on the first day of
each calendar month during such year, in advance. Such payment shall be
construed to be Additional Rent for all purposes hereunder. If at any time
during the course of the fiscal year, Landlord determines that Operating
Expenses are projected to vary from the then Estimated Operating Expenses by
more than five percent (5%), Landlord may, by written notice to Tenant, revise
the Estimated Operating Expenses for the balance of such fiscal year, and
Tenant's monthly installments for the remainder of such year shall be adjusted
so that by the end of such fiscal year Tenant
<PAGE>

has paid to Landlord Tenant's Proportionate Share of the revised Estimated
Operating Expenses for such year, such revised installment amounts to be
Additional Rent for all purposes hereunder.

C. COMPUTATION OF OPERATING EXPENSE ADJUSTMENT. "OPERATING EXPENSE ADJUSTMENT"
shall mean the difference between Estimated Operating Expenses and actual
Operating Expenses for any fiscal year determined as hereinafter provided.
Within one hundred twenty (120) days after the end of each fiscal year, or as
soon thereafter as practicable, Landlord shall deliver to Tenant a statement of
actual Operating Expenses for the fiscal year just ended, accompanied by a
computation of Operating Expense Adjustment. If Such statement shows that
Tenant's payment based upon Estimated Operating Expenses is less than Tenant's
Proportionate Share of operating Expenses, then Tenant shall pay to Landlord the
difference within thirty 30 days after receipt of such statement, such payment
to constitute Additional Rent for all purposes hereunder. If such statement
shows that Tenant's payments of Estimated Operating Expenses exceed Tenant's
Proportionate Share of Operating Expenses, then (provided that Tenant is not in
default under this Lease) Landlord shall pay to Tenant the difference within
twenty (20) days after delivery of such statement to Tenant. If this Lease has
been terminated or the Term hereof has expired prior to the date of such
statement, then the Operating Expense Adjustment shall be paid by the
appropriate party within twenty (20) days after the date of delivery of the
statement. Should this Lease commence or terminate at any time other than the
first day of the fiscal year, Tenant's Proportionate Share of the Operating
Expense Adjustment shall be prorated based on a month of 30 days and the number
of calendar months during such fiscal year that this Lease is in effect.
Notwithstanding anything to the contrary contained in Paragraph 7.A or 7.13,
Landlord's failure to provide any notices or statements within the time periods
specified in those paragraphs shall in no way excuse Tenant from its obligation
to pay Tenant's Proportionate Share of Operating Expenses.

D. NET LEASE. This shall be a triple net Lease and Base Rent shall be paid to
Landlord absolutely net of all costs and expenses, except as specifically
provided to the contrary in this Lease. The provisions for payment of Operating
Expenses and the Operating Expense Adjustment are intended to pass on to Tenant
and reimburse Landlord for all costs and expenses of the nature described in
Paragraph 7.A. incurred in connection with the ownership, management,
maintenance, repair, preservation, replacement and operation of the Building
and/or Project and its supporting facilities and such additional facilities now
and in subsequent years as may be determined by Landlord to be necessary or
desirable to the Building and/or Project.

E. TENANT AUDIT. If Tenant shall dispute the amount set forth in any Statement
provided by Landlord under Paragraph 7.13. or
<PAGE>

7.C. above, Tenant shall have the right, not later than thirty (30) days
following receipt of such statement and upon the condition that Tenant shall
first deposit with Landlord the full amount in dispute, to cause Landlord's
books and records with respect to Operating Expenses for such fiscal year to be
audited by certified public accountants selected by Tenant and subject to
Landlord's reasonable right of approval. The Operating Expense Adjustment shall
be appropriately adjusted on the basis of such audit. If such audit discloses a
liability for a refund in excess of ten percent (10%) of Tenant's Proportionate
Share of the Operating Expenses previously reported, the cost of such audit
shall be borne by Landlord; otherwise the cost of such audit shall be paid by
Tenant. If Tenant shall not request an audit in accordance with the provisions
of this Paragraph 7.E. within twenty (20) days after receipt of Landlord's
statement provided pursuant to Paragraph 7.B. or 7.C., such statement shall be
final and binding for all purposes hereof.

                        8. INSURANCE AND INDEMNIFICATION

         event of condemnation or casualty damage for a period of twelve (12)
         months. Landlord may also (but shall have no obligation to) carry such
         other insurance as Landlord may deem prudent or advisable, including,
         without limitation, liability insurance in such amounts and on such
         terms as Landlord shall determine. Landlord shall not be obligated to

         at any time during the Term the amount or coverage of insurance which
         Tenant is required to carry under this Paragraph S.B. is, in Landlord's
         reasonable judgment, materially less than the amount or type of
         insurance coverage typically carried by owners or tenants of properties
         located in the general area in which the Premises are located which are
         similar to and operated for similar purposes as the Premises or if

         default by Tenant hereunder, procure the same for the account of
         Tenant, and the cost thereof shall be paid to Landlord as Additional
         Rent.

C. INDEMNIFICATION. Tenant shall indemnify, defend by counsel reasonably
acceptable to Landlord, protect and hold Landlord harmless from and against any

this Lease, and (4) claims arising from the negligence or intentional acts or
omissions of Tenant or Tenant's Parties. The foregoing indemnity by Tenant shall
not be applicable to claims to the extent arising from the gross negligence or
willful misconduct of Landlord. Landlord shall not be liable to Tenant and
Tenant hereby waives all claims against Landlord for any injury or damage to any
person or property in or about the Premises, Building or Project by or from any
cause whatsoever (other than Landlord's gross negligence or willful misconduct)
and, without limiting the generality of the foregoing, whether caused by water
leakage of any character from the roof, walls, basement or other portion of the
Premises, Building or Project, or caused by gas, fire, oil or electricity in, on
or about the Premises, Building or Project. The provisions of this Paragraph
shall survive the expiration or earlier termination of this Lease.

                            9. WAIVER OF SUBROGATION

         To the extent permitted by law and without affecting the coverage
provided by insurance to be maintained hereunder or any other rights or
remedies, Landlord and Tenant each waive any right to recover against the other
for: (a) damages for injury to or death of persons; (b) damages to property,
including personal property; (c) damages to the Premises or any part thereof,
and (d) claims arising by reason of the foregoing due to hazards covered by
insurance maintained or required to be maintained pursuant to this Lease to the
extent of proceeds recovered therefrom, or proceeds which would have been
recoverable therefrom in the case of the failure or any party to maintain any
insurance coverage required to be maintained by such party pursuant to this
Lease. This provision is intended to waive fully, any rights and/or claims
arising by reason of the foregoing, but only to the extent that any of the
foregoing damages and/or claims referred to above are covered or would be
covered, and only to the extent of such coverage, by insurance actually carried
or required to be maintained pursuant to this Lease by either Landlord or
Tenant. This provision is also intended to waive fully, and for the benefit of
each party, any rights and/or claims which might give rise to a right of
subrogation on any insurance carrier. Subject to all
<PAGE>

qualifications of this Paragraph 9, Landlord waives its rights as specified in
this Paragraph 9 with respect to any subtenant that it has approved pursuant to
Paragraph 21 but only in exchange for the written waiver of such rights to be
given by such subtenant to Landlord upon such subtenant taking possession of the
Premises or a portion thereof. Each party shall cause each insurance policy
obtained by it to provide that the insurance company waives all right of
recovery by way of subrogation against either party in connection with any
damage covered by any policy.

                     10. LANDLORD'S REPAIRS AND MAINTENANCE

         Landlord shall at Landlord's expense maintain in good repair,

except in the instance of Landlord's gross negligence or wilful misconduct,
arising from the making of repairs, alterations or improvements in or to any
portion of the Premises, the Building or the Project or to fixtures,
appurtenances or equipment in the Building, except as provided in Paragraph 24.
By taking possession of the Premises, Tenant accepts them "as is," as being in
good order, condition and repair and the condition in which Landlord is
obligated to deliver them and suitable for the Permitted Use and Tenant's
intended operations in the Premises, whether or not any notice of acceptance is
given. Tenant shall have period of Ninety (90) days from the Term Commencement
with which to report to Landlord, in writing, any defects with the FIVAQ. roof,
plumbing, electrical or sprinkler systems notice ated by 'Tenant that Landlord

Landlord's sole cost,

                      11. TENANT'S REPAIRS AND MAINTENANCE

all persons signing this Lease on its behalf are authorized to do. Tenant and
the person or persons, if any, signing on behalf of Tenant, jointly and
severally represent and warrant that Tenant has full right and authority to
enter into this Lease, and to perform all of Tenant's obligations hereunder, and
that all persons signing this Lease on its behalf are authorized to do so.

                                23. CONDEMNATION

A. CONDEMNATION RESULTING IN TERMINATION. If the whole or any substantial part
of the Premises should be taken or condemned for any public use under any
Regulation, or by right of eminent domain, or by private purchase in lieu
thereof, and the taking would prevent or materially interfere with the Permitted
Use of the Premises, either party shall have the right to terminate this Lease
at its option. If any material portion of the Building or Project is taken or
condemned for any public use under any Regulation, or by right of eminent
domain, or by private purchase in lieu thereof, Landlord may terminate this
Lease at its option. In either of such events, the Rent shall be abated during
the unexpired portion of this Lease, effective when the physical taking of said
Premises shall have occurred.

B. CONDEMNATION NOT RESULTING IN TERMINATION. If a portion of the Project of
which the Premises are a part should be taken or condemned for any public use
under any Regulation, or by right of eminent domain, or by private purchase in
lieu thereof, and the taking prevents or materially interferes with the
Permitted Use of the Premises, and this Lease is not terminated as provided in
Paragraph 23.A. above, the Rent payable hereunder during the unexpired portion
of this Lease shall be reduced, beginning on the date when the physical taking
shall have occurred, to such amount as may be fair and reasonable under all of
the circumstances, but only after giving Landlord credit for all sums received
or to be received by Tenant by the condemning authority. Notwithstanding
anything to the contrary contained in this Paragraph, if the temporary use or
occupancy of any part of the Premises shall be taken or appropriated under power
of eminent domain during the Term, this Lease shall be and remain unaffected by
such taking or appropriation and Tenant shall continue to pay in full all Rent
payable hereunder by Tenant during the Term; in the event of any such temporary
appropriation or taking, Tenant shall be entitled to receive that portion of any
award which represents compensation for the use of or occupancy of the Premises
during the Term, and Landlord shall be entitled to receive that portion of any
award which represents the cost of
<PAGE>

restoration of the Premises and the use and occupancy of the Premises.

C. AWARD. Landlord shall be entitled to (and Tenant shall assign to Landlord)
any and all payment, income, rent, award or any interest therein whatsoever
which may be paid or made in connection with such taking or conveyance and
Tenant shall have no claim against Landlord or otherwise for any sums paid by
virtue of such proceedings, whether or not attributable to the value of any
unexpired portion of this Lease, except as expressly provided in this Lease.
Notwithstanding the foregoing, any compensation specifically and separately
awarded Tenant for Tenant's personal property and moving costs, shall be and
remain the property of Tenant.

D. WAIVER OF CCP Section 1265.130. Each party waives the provisions of
California Civil Code Procedure Section 1265.130 allowing either party to
petition the superior court to terminate this Lease as a result of a partial
taking.

                               24. CASUALTY DAMAGE

A. GENERAL. If the Premises or Building should be damaged or destroyed by fire,
tornado, or other casualty (collectively, "Casualty"), Tenant shall give
immediate written notice thereof to Landlord. Within thirty (30) days after
Landlord's receipt of such notice, Landlord shall notify Tenant whether in
Landlord's estimation material restoration of the Premises can reasonably be
made within one hundred eighty (180) days from the date of such notice and
receipt of required permits for such restoration. Landlord's determination shall
be binding on Tenant.

B. WITHIN 180 DAYS. If the Premises or Building should be damaged by Casualty to
such extent that material restoration can in Landlord's estimation be reasonably
completed within one hundred eighty ( 180) days after the date of such notice
and receipt of required permits for such restoration, this Lease shall not
terminate. Provided that insurance proceeds are received by Landlord to fully
repair the damage, Landlord shall proceed to rebuild and repair the Premises in
the manner determined by Landlord, except that Landlord shall not be required to
rebuild, repair or replace any part of the Alterations which may have been
placed on or about the Premises by Tenant. If the Premises are untenantable in
whole or in part following such damage, the Rent payable hereunder during the
period in which they are untenantable shall be abated proportionately, but only
to the extent of rental abatement insurance proceeds received by Landlord during
the time and to the extent the Premises are unfit for occupancy.

C. GREATER THAN 180 DAYS. If the Premises or Building should be damaged by
Casualty to such extent that rebuilding or repairs
<PAGE>

cannot in Landlord's estimation be reasonably completed within one hundred
eighty (180) days after the date of such notice and receipt of required permits
for such rebuilding or repair, then Landlord shall have the option of either:
(1) terminating this Lease effective upon the date of the occurrence of such
damage, in which event the Rent shall be abated during the unexpired portion of
this Lease; or (2) electing to rebuild or repair the Premises diligently and in
the manner determined by Landlord. Landlord shall notify Tenant OF its election
within thirty (30) days after Landlord's receipt of notice OF the damage or
destruction. Notwithstanding the above, Landlord shall not be required to
rebuild, repair or replace any part of any Alterations which may have been
placed, on or about the Premises by Tenant. If the Premises are untenantable in
whole or in part following such damage, the Rent payable hereunder during the
period in which they are untenantable shall be abated proportionately, but only
to the extent of rental abatement insurance proceeds received by Landlord during
the time and to the extent the Premises are unfit for occupancy.

D. GREATER THAN 270 DAYS. If the Premises or Building should be damaged by
Casualty to such extent that rebuilding or repairs in Landlord's estimation be
reasonably completed within two hundred seventy (170) days after receipt of
require permits for rebuilding or repair, and such damage materially and
adversely interferes with the conduct of Tenant's business in the Premises, then
either party shall have the right to cancel this Lease by giving the other party
written notice within ten (10) days from the date of Landlord's notice that
material restoration of the Premises cannot be made within such two hundred
severity (270) day period or notice that Landlord has elected not to rebuild or
repair the Premises. Said cancellation shall be effective thirty (30) days from
the first day that either party gives its notice to cancel. If neither party
elects to so cancel this Lease, Landlord shall proceed to rebuild and repair the
Premises diligently and in the manner determined by Landlord, except that
Landlord shall not be required to rebuild, repair or replace any part of any
Alterations which may have been placed on or about the Premises by the Tenant.
If the Premises are untenantable in whole or in part following such damage, the
Rent payable hereunder during the period in which they are untenantable shall be
abated proportionately, but only to the extent of rental abatement proceeds
received by Landlord during the time and to the extent the Premises are unfit
for occupancy.

E. TENANT'S FAULT. Notwithstanding anything herein to the contrary, if the
Premises or any other portion of the Building are damaged by Casualty resulting
from the fault, negligence, or breach of this Lease by Tenant or any of Tenant's
Parties, Base Rent and Additional Rent shall not be diminished during the repair
of such damage and Tenant shall be liable to Landlord for the cost and expense
of the repair and restoration of the Building caused thereby to the extent such
cost and expense is not covered by insurance proceeds.
<PAGE>

F. INSURANCE PROCEEDS. Notwithstanding anything herein to the contrary, if the
Premises or Building are damaged or destroyed and are not fully covered by the
insurance proceeds received by Landlord or if the holder of any indebtedness
secured by a mortgage or deed of trust covering the Premises requires that the
insurance proceeds be applied to such indebtedness, then in either case Landlord
shall have the right to terminate this Lease by delivering written notice of
termination to Tenant within thirty (30) days after the date of notice to
Landlord that said damage or destruction is not fully covered by insurance or
such requirement is made by any such holder, as the case may be, whereupon this
Lease shall terminate.

G. WAIVER. This Paragraph 24 shall be: Tenant's sole and exclusive remedy in the
event of damage or destruction to the Premises or the Building. As a material
inducement to Landlord entering into this Lease, Tenant hereby waives any rights
it may have under Sections 1932, 1933(4), 1941 or 1942 of the Civil Code of
California with respect to any destruction of the Premises, Landlord's
obligation for tenantability of the Premises and Tenant's right to make repairs
and deduct the expenses of such repairs, or under any similar law, statute or
ordinance now or hereafter in effect.

H. TENANT'S PERSONAL PROPERTY. In the event of any damage or destruction of the
Premises or the Building, under no circumstances shall Landlord be required to
repair any injury or damage to, or make any repairs to or replacements of,
Tenant's personal property.

                                25. HOLDING OVER

Unless Landlord expressly consents in writing to Tenant's holding over, Tenant
shall be unlawfully and illegally in possession of the Premises, whether or not
Landlord accepts any rent from Tenant or any other person while Tenant remains
in possession of the Premises without Landlord's written consent. If Tenant
shall retain possession of the Premises or any portion thereof without
Landlord's consent following the expiration of this Lease or sooner termination
for any reason, then Tenant shall pay to Landlord for each day of such retention
150% of the amount of daily rental as of the last month prior to the date of
expiration or earlier termination. Tenant shall also indemnify, defend, protect
and hold Landlord harmless from any loss, liability or cost, including
consequential and incidental damages and reasonable attorneys' fees, incurred by
Landlord resulting from delay by Tenant in surrendering the Premises, including,
without limitation, any claims made by the succeeding tenant founded on such
delay. Acceptance of Rent by Landlord following expiration or earlier
termination of this Lease, or following demand by Landlord for possession of the
Premises, shall not constitute a
<PAGE>

renewal of this Lease, and nothing contained in this Paragraph 25 shall waive
Landlord's right of reentry or any other right. Additionally, if upon expiration
or earlier termination of this Lease, or following demand by Landlord for
possession of the Premises, Tenant has not fulfilled its obligation with respect
to repairs and cleanup of the Premises or any other Tenant obligations as set
forth in this Lease, then Landlord shall have the right to perform any such
obligations as it deems necessary at Tenant's sole cost and expense, and any
time required by Landlord to complete such obligations shall be considered a
period of holding over and the terms of this Paragraph 25 shall apply. The
provisions of this Paragraph 25 shall survive any expiration or earlier
termination of this Lease.

                                   26. DEFAULT

A. EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an
event of default on the part of Tenant:

         (1) ABANDONMENT. Abandonment of the Premises for a continuous period in
         excess of five (5) days. Tenant waives any right to notice Tenant may
         have under Section 1951.3 of the Civil Code of the State of California,
         the terms of this Paragraph 26.A. being deemed such notice to Tenant as
         required by said Section 195 1.3.

         (2) NONPAYMENT OF RENT. Failure to pay any installment of Rent or any
         other amount due and payable hereunder upon the date when said payment
         is due, as to which time is of the essence.

         (3) OTHER OBLIGATIONS. Failure to perform any obligation, agreement or
         covenant under this Lease other than those matters specified in
         subparagraphs (1) and (2) of this Paragraph 26.A., such failure
         continuing for thirty (30) days after written notice of such failure,
         as to which time is of the essence.

         (4) GENERAL ASSIGNMENT. A general assignment by Tenant for the benefit
         of creditors.

         (5) BANKRUPTCY. The filing of any voluntary petition in bankruptcy by
         Tenant, or the filing of an involuntary petition by Tenant's creditors,
         which involuntary petition remains undischarged for a period of thirty
         (30) days. If under applicable law, the trustee in bankruptcy or Tenant
         has the right to affirm this Lease and continue to perform the
         obligations of Tenant hereunder, such trustee or Tenant shall, in such
         time period as may be permitted by the bankruptcy court having
         jurisdiction, cure all defaults of Tenant hereunder outstanding as of
         the date of the affirmance of this Lease and provide to Landlord such
<PAGE>

         adequate assurances as may be necessary to ensure Landlord of the
         continued performance of Tenant's obligations under this Lease.

         (6) RECEIVERSHIP. The employment of a receiver to take possession of
         substantially all of Tenant's assets or the Premises, if such
         appointment remains undismissed or undischarged for a period of fifteen
         (15) days after the order therefor.

         (7) ATTACHMENT. The attachment, execution or other judicial seizure of
         all or substantially all of Tenant's assets or Tenant's leasehold of
         the Premises, if such attachment or other seizure remains undismissed
         or undischarged for a period of fifteen (15) days after the levy
         thereof.

         (8) INSOLVENCY. The admission by Tenant in writing of its inability to
         pay its debts as they become due.

B.       REMEDIES UPON DEFAULT.

         (1) TERMINATION. In the event of the occurrence of any event of
         default, Landlord shall have the rig ht to give a written termination
         notice to Tenant, and on the date specified in such notice, Tenant's
         right to possession shall terminate, and this Lease shall terminate
         unless on or before such date all Rent in arrears and all costs and
         expenses incurred by or on behalf of Landlord -hereunder shall have
         been paid by Tenant and all other events of default of this Lease by
         Tenant at the time existing shall have been fully remedied to the
         satisfaction of Landlord. At any time after such termination, Landlord
         may recover possession of the Premises or any part thereof and expel
         and remove therefrom Tenant and any other person occupying the same,
         including any subtenant or subtenants notwithstanding Landlord's
         consent to any sublease, by any lawful means, and again repossess and
         enjoy the Premises without prejudice to any of the remedies that
         Landlord may have under this Lease, or at law or equity by any reason
         of Tenant's default or of such termination. Landlord hereby reserves
         the right, but shall not have the obligation, to recognize the
         continued possession of any subtenant. The delivery or surrender to
         Landlord by or on behalf of Tenant of keys, entry codes, or other means
         to bypass security at the Premises shall not terminate this Lease.

         (2) CONTINUATION AFTER DEFAULT. Even though an event of default may
         have occurred, this Lease shall continue in effect for so long as
         Landlord does not terminate Tenant's right to possession under
         Paragraph 26.B.(I) hereof, and Landlord may enforce all of Landlord's
         rights and remedies
<PAGE>

         under this Lease and at law or in equity, including without limitation,
         the right to recover Rent as it becomes due, and Landlord, without
         terminating this Lease, may exercise all of the rights and remedies of
         a landlord under Section 1951.4 of the Civil Code of the State of
         California or any successor code section. Acts of maintenance,
         preservation or efforts to lease the Premises or the appointment of a
         receiver under application of Landlord to protect Landlord's interest
         under this Lease or other entry by Landlord upon the Premises shall not
         constitute an election to terminate Tenant's right to possession.

         (3) INCREASED SECURITY DEPOSIT. If Tenant is in default under Paragraph
         26.A.(2) hereof and such default remains uncured for thirty (30) days
         after such occurrence or such default occurs more than three times in
         any twelve (12) month period, Landlord may require that Tenant increase
         the Security Deposit to the amount of three times the current month's
         Rent at the time of the most recent default.

C. DAMAGES AFTER DEFAULT. Should Landlord terminate this Lease pursuant to the
provisions of Paragraph 26.B.(I) hereof, Landlord shall have the rights and
remedies of a Landlord provided by Section 1951.2 of the Civil Code of the State
of California, or any successor code sections. Upon such termination, in
addition to any other rights and remedies to which Landlord may be entitled
under applicable law or at equity, Landlord shall be entitled to recover from
Tenant: (1) the worth at the time of award of the unpaid Rent and other amounts
which had been earned at the time of termination, (2) the worth at the time of
award of the amount by which the unpaid Rent and other amounts that would have
been earned after the date of termination until the time of award exceeds the
amount of such Rent loss that Tenant proves could have been reasonably avoided;
(3) the worth at the time of award of the amount by which the unpaid Rent and
other amounts for the balance of the Term after the time of award exceeds the
amount of such Rent loss that the Tenant proves could be reasonably avoided; and
(4) any other amount and court costs necessary to compensate Landlord for all
detriment proximately caused by Tenant's failure to perform Tenant's obligations
under this Lease or which, in the ordinary course of things, would be likely to
result therefrom. The "worth at the time of award" as used in (1) and (2) above
shall be computed at the Applicable Interest Rate (defined below). The "worth at
the time of award" as used in (3) above shall be computed by discounting such
amount at the Federal Discount Rate of the Federal Reserve Bank of San Francisco
at the time of award plus one percent (1%). If this Lease provides for any
periods during the Term during which Tenant is not required to pay Base Rent or
if Tenant otherwise receives a Rent concession, then upon the occurrence of an
event of default, Tenant shall owe to Landlord the full amount of such Base Rent
or value of such Rent concession, plus interest at the Applicable Interest Rate,
<PAGE>

calculated from the date that such Base Rent or Rent concession would have been
payable.

D. LATE CHARGE. In addition to its other remedies, Landlord shall have the right
without notice or demand to add to the amount of any payment required to be made
by Tenant hereunder, and which is not paid and received by Landlord on or before
the first day of each calendar month, an amount equal to ten percent (10%) of
the delinquency for each month or portion thereof that the delinquency remains
outstanding to compensate Landlord for the loss of the use of the amount not
paid and the administrative costs caused by the delinquency, the parties
agreeing that Landlord's damage by virtue of such delinquencies would be
extremely difficult and impracticable to compute and the amount stated herein
represents a reasonable estimate thereof. Any waiver by Landlord of any late
charges or failure to claim the same shall not constitute a waiver of other late
charges or any other remedies available to Landlord. Landlord shall waive late
fee one time per year.

E. INTEREST. Interest shall accrue on all sums not paid when due hereunder at
the lesser of eighteen percent (18%) per annum or the maximum interest rate
allowed by law ("Applicable Interest Rate") from the due date until paid.

F. REMEDIES CUMULATIVE. All rights, privileges and elections or remedies of the
parties are cumulative and not alternative, to the extent permitted by law and
except as otherwise provided herein.

                                    27. LIENS

Tenant shall at all times keep the Premises and the Project free from liens
arising out of or related to work or services performed, materials or supplies
furnished or obligations incurred by or on behalf of Tenant or in connection
with work made, suffered or done by or on behalf of Tenant in or on the Premises
or Project. If Tenant shall not, within ten (10) days following the imposition
of any such lien, cause the same to be released of record by payment or posting
of a proper bond, Landlord shall have, in addition to all other remedies
provided herein and by law, the right, but not the obligation, to cause the same
to be released by such means as Landlord shall deem proper, including payment of
the claim giving rise to such lien. All sums paid by Landlord on behalf of
Tenant and all expenses incurred by Landlord in connection therefor shall be
payable to Landlord by Tenant on demand with interest at the Applicable Interest
Rate as Additional Rent. Landlord shall have the right at all times to post and
keep posted on the Premises any notices permitted or required by law, or which
Landlord shall deem proper, for the protection of Landlord, the Premises, the
Project and any other party having an interest therein, from mechanics' and
materialmen's liens, and Tenant shall give Landlord not less
<PAGE>

than ten (10) business days prior written notice of the commencement of any work
in the Premises or Project which could lawfully give rise to a claim for
mechanics' or materiaimen's liens to permit Landlord to post and record a timely
notice of non-responsibility, as Landlord may elect to proceed or as the law may
from time to time provide, for which purpose, if Landlord shall so determine,
Landlord may enter the Premises. Tenant shall not remove any such notice posted
by Landlord without Landlord's consent, and in any event not before completion
of the work which could lawfully give rise to a claim for mechanics' or
materialmen's liens.

                            29. TRANSFERS BY LANDLORD

In the event of a sale or conveyance by Landlord of the Building or a
foreclosure by any creditor of Landlord, the same shall operate to release
Landlord from any liability upon any of the covenants or conditions, express or
implied, herein contained in favor of Tenant, to the extent required to be
performed after the passing of title to Landlord's successor-in-interest. In
such event, Tenant agrees to look solely to the responsibility of the
successor-in-interest of Landlord under this Lease with respect to the
performance of the covenants and duties of "Landlord" to be performed after the
passing of title to Landlord's successor-in-interest. This Lease shall not be
affected by any such sale and Tenant agrees to attorn to the purchaser or
assignee. Landlord's successor(s)-in-interest shall not have liability to Tenant
with respect to the failure to perform any of the obligations of"Landlord," to
the extent required to be performed prior to the date such
successor(s)-in-interest became the owner of the Building.

               30. RIGHT OF LANDLORD TO PERFORM TENANT'S COVENANTS

All covenants and agreements to be performed by Tenant under any of the terms of
this Lease shall be performed by Tenant at Tenant's sole cost and expense and
without any abatement of Rent. If Tenant shall fail to pay any sum of money,
other than Base Rent, required to be paid by Tenant hereunder or shall fail to
perform any other act on Tenant's part to be performed hereunder, including
Tenant's obligations under Paragraph 11 hereof, and such failure shall continue
for fifteen (15) days after notice thereof by Landlord, in addition to the other
rights and remedies of Landlord, Landlord may make any such payment and perform
any such act on Tenant's part. In the case of an emergency, no prior
notification by Landlord shall, be required. Landlord may take such actions
without any obligation and without releasing Tenant from any of Tenant's
obligations. All sums so paid by Landlord and all incidental costs incurred by
Landlord and interest thereon at the Applicable Interest Rate, from the date of
payment by Landlord, shall be paid to Landlord on demand as Additional Rent.
<PAGE>

                                   31. WAIVER

If either Landlord or Tenant waives the performance of any term, covenant or
condition contained in this Lease, such waiver shall not be deemed to be a
waiver of any subsequent breach of the same or any other term, covenant or
condition contained herein, or constitute a course of dealing contrary to the
expressed terms of this Lease. The acceptance of Rent by Landlord shall not
constitute a waiver of any preceding breach by Tenant of any term, covenant or
condition of this Lease, regardless of Landlord's knowledge of such preceding
breach at the time Landlord accepted such Rent. Failure by Landlord to enforce
any of the terms, covenants or conditions of this Lease for any length of time
shall not be deemed to waive or decrease the right of Landlord to insist
thereafter upon strict performance by Tenant. Waiver by Landlord of any term,
covenant or condition contained in this Lease may only be made by a written
document signed by Landlord, based upon full knowledge of the circumstances.

                                   32. NOTICES

Each provision of this Lease or of any applicable governmental laws, ordinances,
regulations and other requirements with reference to sending, mailing, or
delivery of any notice or the making of any payment by Landlord or Tenant to the
other shall be deemed to be complied with when and if the following steps are
taken:

A. RENT. All Rent and other payments required to be made by Tenant to Landlord
hereunder shall be payable to Landlord at Landlord's Remittance Address set
forth in the Basic Lease Information, or at such other address as Landlord may
specify from time to time by written notice delivered in accordance herewith.
Tenant's obligation to pay Rent and any other amounts to Landlord under the
terms of this Lease shall not be deemed satisfied until such Rent and other
amounts have been actually received by Landlord.

B. OTHER. All notices, demands, consents and approvals which may or are required
to be given by either party to the other hereunder shall be in writing and
either personally delivered, sent by commercial overnight courier, mailed,
certified or registered, postage prepaid or sent by facsimile with confirmed
receipt (and with an original sent by commercial overnight courier), and in each
case addressed to the party to be notified at the Notice Address for such party
as specified in the Basic Lease Information or to such other place as the party
to be notified may from time to time designate by at least fifteen (15) days
notice to the notifying party. Notices shall be deemed served upon receipt or
refusal to accept delivery. Tenant appoints as its agent to receive the service
of all default notices and notice of commencement of unlawful detainer
<PAGE>

proceedings the person in charge of or apparently in charge of occupying the
Premises at the time, and, if there is no such person, then such service may be
made by attaching the same on the main entrance of the Premises.

C. REQUIRED NOTICES. Tenant shall immediately notify Landlord in writing of any
notice of a violation or a potential or alleged violation of any Regulation that
relates to the Premises or the Project, or of any inquiry, investigation,
enforcement or other action that is instituted or threatened by any governmental
or regulatory agency against Tenant or any other occupant of the Premises, or
any claim that is instituted or threatened by any third party that relates to
the Premises or the Project.

                               33. ATTORNEYS' FEES

If Landlord places the enforcement of this Lease, or any part thereof, OR the
collection of any Rent due, or to become due hereunder, or recovery of
possession of the Premises in the hands of an attorney, Tenant shall pay to
Landlord, upon demand, Landlord's reasonable attorneys' fees and court costs,
whether incurred at trial, appeal or review. In any action which Landlord or
Tenant brings to enforce its respective rights hereunder, the unsuccessful party
shall pay all costs incurred by the prevailing party including reasonable
attorneys' fees, to be fixed by the court, and said costs and attorneys' fees
shall be a part of the judgment in said action.

                           34. SUCCESSORS AND ASSIGNS

This Lease shall be binding upon and inure to the benefit of Landlord, its
successors and assigns, and shall be binding upon and inure to the benefit of
Tenant, its successors, and to the extent assignment is approved by Landlord as
provided hereunder, Tenant's assigns.

                                35. FORCE MAJEURE

If performance by a party of any portion of this Lease is made impossible by any
prevention, delay, or stoppage caused by strikes, lockouts, labor disputes, acts
of God, inability to obtain services, labor, or materials or reasonable
substitutes for those items, government actions, civil commotions, fire or other
casualty, or other causes beyond the reasonable control of the party obligated
to perform, performance by that party for a period equal to the period of that
prevention, delay, or stoppage is excused. Tenant's obligation to pay Rent,
however, is not excused by this Paragraph 35.
<PAGE>

                            36. SURRENDER OF PREMISES

Tenant shall, upon expiration or sooner termination of this Lease, surrender the
Premises to Landlord in the same condition as existed on the date Tenant
originally took possession thereof, including, but not limited to, all interior
walls cleaned, all holes in walls repaired, all carpets shampooed and cleaned,
all HVAC equipment in operating order and in good repair, and all floors
cleaned, waxed, and free of any Tenant-introduced marking or painting, all to
the reasonable satisfaction of Landlord. Tenant shall remove all of its debris
from the Project. At or before the time of surrender, Tenant shall comply with
the terms of Paragraph 12.A. hereof with respect to Alterations to the Premises
and all other matters addressed in such Paragraph. If the Premises are not so
surrendered at the expiration or sooner termination of this Lease, the
provisions of Paragraph 25 hereof shall apply. Al I keys to the Premises or any
part thereof shall be surrendered to Landlord upon expiration or sooner
termination of the Term. Tenant shall give written notice to Landlord at least

reasonable efforts to adapt and compensate for such delays. In addition, no
Landlord Delays shall be deemed to have occurred unless Tenant has provided
notice, in compliance with the Lease, to Landlord specifying that a delay shall
be deemed to have occurred because of actions, inactions or circumstances
specified in the notice in reasonable detail. If such actions, inactions or
circumstances are not cured by Landlord within one (1) business day after

circumstances otherwise qualify as a Landlord Delay, then a Landlord Delay shall
be deemed to have occurred commencing as of the Count Date. The Term

to act, of Landlord, its agents or contractors, where such acts or failures to
act delay the completion of the Tenant Improvements, provided that Tenant acts
in a commercially reasonable manner to mitigate any such delay, (iii) delays due
to the interference of Landlord, its agents or contractors with the completion
of the Tenant Improvements or the failure or refusal of any party to permit
Tenant, its agents and contractors, access to and use of the Building or any
Building facilities or services, including elevators and loading docks, which
access and use are necessary to complete the Tenant Improvements, and (iv)
delays due to Landlord's failure to allow Tenant sufficient access to the
Building and/or the Premises during Tenant's move into the Premises.

         7.2 Within ten (10) days after completion of construction of the Tenant
Improvements, Tenant shall cause a Notice of Completion to be recorded in the
office of the Recorder of the county in which the Building is located in
accordance with Section 3093 of the Civil Code of the State of California or
any successor statute, and shall furnish a copy thereof to Landlord

upon such recordation. If Tenant fails to do so, Landlord may execute and file
the same on behalf of Tenant as Tenant's agent for such purpose, at Tenant's
sole cost and expense. At the conclusion of construction, (i) Tenant shall cause
the Space Planner and the contractor (i) to update the approved working drawings
as necessary to reflect all changes made to the approved working drawings during
the course of construction, (ii) to certify to the best of their knowledge that
the "record-set" of as-built drawings are true and correct, which certification
shall survive the expiration or termination of' the Lease, and (c) to deliver to
Landlord two (2) sets of copies of such record set of drawings within ninety
(90) days following issuance of certificate of occupancy for the Premises, and
(iii) Tenant shall deliver to Landlord a copy of all warranties, guarantees, and
operating manuals and information relating to the improvements, equipment, and
systems in the Premises.

         7.3 A default under this Improvement Agreement shall constitute a
default under the Lease, and the parties shall be entitled to all rights and
remedies under the Lease in the event of a default hereunder by the other party
(notwithstanding that the Term thereof has not commenced).
<PAGE>

         7.4 Without limiting the "as-is" provisions of the Lease, except for
the Tenant Improvements, if any, to be constructed by Landlord pursuant to this
Improvement Agreement, Tenant accepts the Premises in its "as-is" condition and
acknowledges that it has had an opportunity to inspect the Premises prior to
signing the Lease.

the purpose of performing the Tenant Improvement work before the Scheduled
Commencement Date, so long as such entry does not interfere with the Landlord's
construction.
