             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
1. QUARTERLY FINANCIAL STATEMENTS
 
  The condensed consolidated financial statements and related notes for the
three months and nine months ended July 31, 1997 and 1996 are unaudited but
include all adjustments (consisting solely of normal recurring adjustments)
which are, in the opinion of management, necessary for a fair presentation of
financial position and results of operations of the Company for the interim
periods. The results of operations for the three months and nine months ended
July 31, 1997 and 1996 are not necessarily indicative of the operating results
to be expected for the full fiscal year. The information included in this
report should be read in conjunction with the Company's audited consolidated
financial statements and notes thereto for the fiscal year ended October 31,
1996 included in the Annual Report on Form 10-K and the risk factors,
including, without limitation, risks relating to fluctuations in operating
results, rapid technological change, importance of timely product
introduction, risks of delays, limited system sales, backlog, cyclicality of
semiconductor industry, expansion of operations, sole or limited sources of
supply, reliance on subcontractors, highly competitive industry, dependence on
key customers, lengthy sales cycle, dependence on key personnel, international
sales, proprietary rights, acquisitions, future capital needs and volatility
of stock price, as set forth in this Report. Any party interested in reviewing
these publicly available documents should write to the SEC or the Chief
Financial Officer of the Company.
 
  USE OF ESTIMATES--The preparation of the accompanying unaudited consolidated
condensed financial statements requires management to make estimates and
assumptions that affect the amounts reported in the financial statements.
Actual results could differ from those estimates.
 
2. INVENTORIES
 
  Inventories are stated at the lower of standard cost (which approximates
first-in, first-out cost) or market. Inventories consist of the following (in
thousands):

3. NET INCOME (LOSS) PER SHARE
 
  Net income (loss) per share is based upon the weighted average number of
common and dilutive common equivalent shares (stock options) outstanding
during the period.
 
  In March 1997, the Financial Accounting Standards Board ("FASB") released
Statement of Financial Accounting Standards No. 128 "Earnings Per Share" ("FAS
128"), which is required to be adopted on December 31, 1997. At that time, the
Company will be required to change the method currently used to compute
earnings per share and to restate all prior periods. Under the new
requirements for calculating primary net income per share (basic earnings per
share), the dilutive effect of stock options will be excluded. The Company's

                         CREDENCE SYSTEMS CORPORATION
 
       NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
4. CONTINGENCIES
 
  The Company's litigation matters with Megatest Corporation and Teradyne,
Inc., have been resolved. There was no impact on the financial statements as a
result of these settlements.
 
  The Company is involved in various claims arising in the ordinary course of
business, none of which, in the opinion of management, if determined adversely
against the Company, will have a material adverse effect on the Company's
business, financial condition or results of operations.
 
5. ACQUISITION OF THE TEST DEVELOPMENT SERIES BUSINESS OF TEST SYSTEMS
   STRATEGIES, INC. AND SUMMIT DESIGN, INC.
 
  On July 11, 1997, the Company, through its newly formed subsidiary, Test
Systems Strategies, Inc., a Delaware Corporation ("TSSI"), acquired certain
assets and assumed certain liabilities from Summit Design, Inc. and its wholly
owned subsidiary, Test Systems Strategies, Inc., an Oregon Corporation,
including the test development series software ("TDS") and TSSI trademark of
Test Systems Strategies, Inc. (an Oregon Corporation). TDS includes tools
designed to convert gate-level simulation data from electronic design
automation simulators to programs that operate on targeted automatic test
equipment ("ATE") for testing integrated circuits characterized by the gate-
level simulation data. TDS facilitates simulation analysis, stimulus
generation, simulation rules checking, tester resource checking, ATE test
program generation, and test program conversion. The acquisition has been
accounted for by the Company under the purchase method of accounting, and
accordingly, the condensed consolidated financial statements reflect the
impact of TDS operations subsequent to the acquisition date.
 
  The purchase price of $7.3 million, consisted of a cash payment of $7.0
million to Summit Design, Inc. and $300,000 for the assumption of liabilities.
Acquired assets and liabilities were recorded at their estimated fair market
value at the date of the acquisition. The aggregate purchase price, plus
related acquisition expenses, have been allocated to the assets and
liabilities acquired based on valuations. Amounts allocated to in-process
research and development of approximately $6.0 million were written-off at the
acquisition date, representing an estimated value (using risk-adjusted cash
flows, discounted at 35%) of development programs that have not yet reached
technological feasibility. Amounts allocated to developed technology, $1.0
million, and workforce in place, $0.3 million, are being amortized on a
straight line basis over periods of six and three years respectively.
 
6. COMMITMENTS
 
  In addition on May 19, 1997, the Company entered into an agreement with
Summit Design, Inc. for the Company to purchase approximately $18 million of
Summit's Visual Testbench ("VTB") product licenses and maintenance services
through 1999. The restricted cash on the accompanying balance sheet relates to
the amounts yet to be purchased under this agreement.
 
7. SUBSEQUENT EVENTS
 
  On August 20, 1997, the Company through one of its subsidiaries, Test
Systems Strategies, Inc., purchased from Zycad Corporation ("Zycad") and one
of its subsidiaries, Attest Software, Inc. certain assets and assumed certain
liabilities for $2,250,000.
 
  On September 10, 1997, the Company sold $100 million of 5 1/4% convertible
subordinated notes (the "Notes") due 2002 through a private placement within
the U.S. to qualified institutional buyers in accordance with Rule 144A and
outside the U.S., to non-U.S. persons as defined in Regulation S under the
Securities Act of 1933, as amended. The Notes are convertible into common
stock of the Company at a conversion price of $69.15 per share. The Company
has granted to Smith Barney, Inc., the initial purchaser, a 30-day option to
purchase an additional $15 million of Notes to cover over-allotments, if any.
Expense of $3.0 million associated with the offering will be deferred and
included in other assets. Such expenses will be amortized to interest expense
over the term of the Notes.

RESULTS OF OPERATIONS
 
NET SALES
 
  Net sales consist of revenues from systems sales, spare parts sales and
maintenance contracts. Net sales were $51.1 million for the third quarter and
$134.7 for the first nine months of fiscal 1997, representing decreases of
24.0% and 30.8%, respectively, over the comparable periods of fiscal 1996.
These decreases were due primarily to a significant weakness in the ATE market
which materially adversely affected the Company and several other companies in
the capital equipment market. International net sales accounted for
approximately 71.3% and 70.0% of the total net sales for the third quarter and
first nine months of fiscal 1997 respectively, compared to approximately 61.2%
and 65.1% for the comparable periods a year ago. The Company's international
sales of its products and spare parts and its service revenues are denominated
primarily in United States dollars.
 
GROSS MARGIN
 
  The Company's gross margin has been and will continue to be affected by a
variety of factors, including manufacturing efficiencies, pricing by
competitors or suppliers, new product introductions, product sales mix,
production volume, product reliability, customization and reconfiguration of
systems, reserves, international and domestic sales mix and field service
margins. Gross margin was 57.6% for the third quarter and 55.9% for the first
nine months of fiscal 1997, compared with 59.7% for the third quarter and
59.9% for the first nine months
 
                                       8
<PAGE>
 
of fiscal 1996. The reduction in gross margin as a percent of sales was due
primarily to an increase in the first quarter of fiscal 1997 in inventory
write down reserves on slower moving parts of older products and changes in
product mix.
 
RESEARCH AND DEVELOPMENT
 
  Research and development expenses were $9.3 million in the third quarter of
fiscal 1997, a slight decrease of $0.3 million or 3.5% as compared to the
third quarter of fiscal 1996. Research and development expenses were $27.0
million in the first nine months of fiscal 1997, which was comparable, in
dollars, to expenses for the first nine months of fiscal 1996. As a percentage
of net sales, these expenses were 18.1% for the third quarter and 20.0% for
the first nine months of fiscal 1997, compared with 14.3% for the third
quarter and 14.0% for the first nine months of 1996. The increase of these
expenses as a percentage of net sales is attributable primarily to the
significant decrease in net sales in fiscal 1997 as compared with the
comparable periods of fiscal 1996. For the foreseeable future, the Company
currently intends to continue to invest significant resources in the
development of new products and enhancements. Accordingly, the Company expects
these expenses to increase in dollars for the remainder of fiscal 1997 as
compared to fiscal 1996 due to the introduction of new products in the latter
half of the year.
 
SELLING, GENERAL AND ADMINISTRATIVE
 
  Selling, general and administrative expenses were $14.5 million in the third
quarter and $37.9 million for the first nine months of fiscal 1997,
representing an increase of $0.8 million or 6.1% in the third quarter of
fiscal 1997 and a decrease of $2.6 million or 6.5% for the first nine months
of fiscal 1997, compared to the comparable periods of fiscal 1996. As a
percentage of net sales, these expenses were 28.4% for the third quarter and
28.2% for the first nine months of fiscal 1997, compared with 20.4% and 20.9%,
respectively, for the corresponding periods in fiscal 1996. The increase of
these expenses as a percentage of net sales is attributable primarily to the
significant decrease in net sales in fiscal 1997 as compared with the
comparable periods of fiscal 1996. The Company expects selling, general and
administrative expenses for the rest of fiscal 1997 to increase in dollars as
compared to fiscal 1996 due to the introduction of new products in the latter
half of the year.
 
INTEREST INCOME, NET
 
  The Company generated net interest income of $1.0 million for the third
quarter and $2.9 million for the first nine months of fiscal 1997, compared to
$989,000 and $3.1 million, respectively, for the corresponding periods of
fiscal 1996. The slight decrease for the nine months of fiscal 1997 was due
primarily to interest earned on lower average cash and cash equivalents and
short-term investments balances during the period. The lower cash and cash
equivalents and short-term investments balances reflected decreased cash
provided by operations.
 
INCOME TAXES
 
  Excluding the impact of the in-process R&D charge, the Company's provision
for income taxes for the third quarter and the first nine months of fiscal
1997 is computed based on the projected annualized effective tax rate of
33.5%. The effective tax rate for the third quarter and the first nine months
of fiscal 1996 was 35.2% and 35.5%, respectively. Excluding the impact of the
in-process R&D charge, the projected effective tax rate for fiscal 1997 is
expected to be less than the combined federal and state statutory tax rate,
and the 1996 effective tax rate, primarily due to the projected benefit of the
Company's foreign sales corporation.
 
                                       9
<PAGE>
 
  The tax provision for the first nine months of 1997 consists of two items: a
$4,420,000 provision on pre-tax book income of $13,194,000 (for a 33.5%
effective tax rate exclusive of the in-process R & D charge), and a $693,000
tax benefit on the $6,022,000 in-process R&D charge.
 
  A valuation allowance has been established in the third quarter of fiscal
1997 to offset a portion of the deferred tax asset attributable to the in-
process R&D charge. Due to the period over which this tax benefit will be
recognized, sufficient uncertainty exists regarding the realizability of a
portion of these assets, and accordingly, a valuation allowance is required.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Net cash provided (used) by operating activities was ($3.4 million) and
$31.7 million for the nine months ended July 31, 1997 and 1996, respectively.
Net cash flows used by operating activities for the nine months ended July 31,
1997 were primarily attributable to a decrease in accounts receivable, offset
in part by an increase in inventory, $11.7 million of which was transferred to
property and equipment, and reductions in accounts payable ($3.0 million) and
accrued liabilities ($2.5 million). Investing activities provided net cash of
$8.7 million and used net cash of $32.7 million for the nine months ended July
31, 1997 and 1996, respectively. In the first nine months of fiscal 1997, the
Company experienced a net reduction of $14.1 million in short-term investments
while also purchasing $7.8 million of property and equipment. Net cash
provided by financing activities was $2.0 million and $0.9 million for the
nine months ended July 31, 1997 and 1996, respectively.
 
  As of July 31, 1997, the Company had working capital of approximately $141.3
million, including cash of $42.8 million, restricted cash of $13.1 million,
and short-term investments of $23.5 million, $44.0 million of accounts
receivable and $36.4 million of inventories. The Company expects accounts
receivable to continue to represent a significant portion of working capital.
The Company believes that because of the relatively long manufacturing cycles
of many of its testers, investments in inventories will also continue to
represent a significant portion of working capital. Additionally, the Company
expects to continue investing in inventories for its new products, which may
be slower moving at the beginning of the product introduction cycle.
Significant investments in accounts receivable and inventories may subject the
Company to increased risks which could materially adversely affect the
Company's business, financial condition and results of operations. Total
liabilities of $33.3 million as of October 31, 1996 decreased to $29.8 million
as of July 31, 1997. The $3.5 million decrease was due primarily to decreases
in accounts payable of $3.0 million.
 
  The Company has entered into an agreement with Summit Design, Inc. for the
Company to purchase approximately $18 million of VTB product licenses and
maintenance services through 1999. The restricted cash relates to the amounts
yet to be purchased under this agreement.
 
  The Company's principal sources of liquidity as of July 31, 1997 consisted
of approximately $55.9 million of cash and cash equivalents and restricted
cash, short-term investments of $23.5 million and $20.0 million available
under the Company's unsecured working capital line of credit expiring on July
24, 1998. As of July 31, 1997, no amounts were outstanding under the line of
credit. Additionally, as of July 31, 1997, the Company has operating leases
for test and other equipment with remaining payments totaling approximately
$2.6 million.
 
  On September 10, 1997, the Company sold $100 million of 5 1/4% convertible
subordinated notes (the "Notes") due 2002 through a private placement within
the U.S. to qualified institutional buyers in accordance with Rule 144A and
outside the U.S., to non-U.S. persons as defined in Regulation S under the
Securities Act of 1933, as amended. The Notes are convertible into common
stock of the Company at a conversion price of $69.15 per share. The Company
has granted to Smith Barney, Inc., the initial purchaser, a 30-day option to
purchase an additional $15 million of Notes to cover over-allotments, if any.
Expense of $3.0 million associated with the offering will be deferred and
included in other assets. Such expenses will be amortized to interest expense
over the term of the Notes.
 
RISK FACTORS
 
  The Company's results of operations are affected by a variety of factors,
including the following:
 
 
                                      10
<PAGE>
 
Fluctuations in Operating Results
 
  The Company's operating results have in the past fluctuated significantly
and will in the future fluctuate significantly, due to a variety of factors.
The Company's operating performance from the first quarter of fiscal 1993
through the third quarter of fiscal 1996 produced sequential quarter-to-
quarter growth in both net sales and net income. In the fourth quarter of
fiscal 1996, however, net sales decreased 34% from the third quarter of fiscal
1996 and 17% from the fourth quarter of fiscal 1995. Net income for the fourth
quarter of fiscal 1996 decreased 63% from the third quarter of fiscal 1996 and
55% from the fourth quarter of fiscal 1995. In the first quarter of fiscal
1997, net sales decreased 9% from the fourth quarter of fiscal 1996 and
decreased 34% from the first quarter of fiscal 1996. Net income for the first
quarter of fiscal 1997 decreased 75% from the fourth quarter of fiscal 1996
and decreased 90% from the first quarter of fiscal 1996. In the second quarter
of fiscal 1997, net sales increased 8% from the first quarter of fiscal 1997
and decreased 35% from the second quarter of fiscal 1996. Net income for the
second quarter of fiscal 1997 increased 212% from the first quarter of fiscal
1997 and decreased 71% from the second quarter of fiscal 1996. In the third
quarter of fiscal 1997, net sales increased 15% from the second quarter of
fiscal 1997 but decreased 24% from the third quarter of fiscal 1996. The
Company incurred a net loss of $897,000 for the third quarter of fiscal 1997
resulting in a decrease of 127% when compared to the $3.3 million net income
for the second quarter of fiscal 1997 and a 108% decrease from the third
quarter of fiscal 1996. The decreases were due primarily to a significant
weakness in the ATE market which materially adversely affected the Company and
several other companies in the semiconductor equipment industry. The factors
that have caused and will continue to cause the Company's results to fluctuate
include the timing of new product announcements and releases by the Company or
its competitors, market acceptance of new products and enhanced versions of
the Company's products, manufacturing inefficiencies associated with the start
up of new products, changes in pricing by the Company, its competitors,
customers or suppliers, manufacturing capacity, the ability to volume produce
systems and meet customer requirements, inventory obsolescence, patterns of
capital spending by customers, delays, cancellations or reschedulings of
orders due to customer financial difficulties or otherwise, changes in
overhead absorption levels due to changes in the number of systems
manufactured, the timing and shipment of orders, availability of components,
subassemblies and services, expenses associated with acquisitions and
alliances, product discounts, customization and reconfiguration of systems,
product reliability, the proportion of direct sales and sales through third
parties, including distributors and original equipment manufacturers, the mix
of products sold, the length of manufacturing and sales cycles, cyclicality or
downturns in the semiconductor market and the markets served by the Company's
customers, natural disasters, political and economic instability, regulatory
changes and outbreaks of hostilities. The Company presently intends to
introduce many new products and product enhancements in this current fiscal
year, which will affect its operating results, financial condition and
business. The Company's gross margins on system sales have varied
significantly, especially in the last twelve months, and will continue to vary
significantly based on a variety of factors, including manufacturing
efficiencies, pricing by competitors or suppliers, product sales mix,
reserves, production volume, new product introductions, product reliability,
customization and reconfiguration of systems, international and domestic sales
mix and field service margins. In addition, new and enhanced products
typically have lower gross margins in the early stages of commercial
introduction and production. While the Company has recorded and continues to
record allowances for estimated sales returns and uncollectable accounts,
there can be no assurance that such estimates regarding allowances will be
adequate.
 
Limited System Sales; Backlog
 
  The Company derives a substantial portion of its net sales from the sale of
a relatively small number of systems that typically range in price from
$350,000 to $2.0 million, excluding the current memory products, for which the
price range is typically below $100,000. As a result, the timing of
recognition of revenue from a single transaction could have a significant
impact on the Company's net sales and operating results for a particular
period. The Company's net sales and operating results for a particular period
could be materially adversely affected if an anticipated order for even one
system is not received in time to permit shipment during that period. The
Company's backlog at the beginning of a quarter typically does not include all
tester orders needed to achieve the Company's sales objectives for that
quarter. In addition, orders in backlog are subject to cancellation, delay,
deferral or rescheduling by a customer with limited or no penalties.
Consequently, the Company's net
 
                                      11
<PAGE>
 
sales and operating results for a quarter have in the past and will in the
future depend upon the Company obtaining orders for systems to be shipped in
the same quarter that the order is received. Furthermore, products generating
most of the Company's net sales continue to be shipped near the end of each
quarter. Accordingly, the failure to receive an anticipated order or a delay
or rescheduling in a shipment near the end of a particular period due, for
example, to an order cancellation, a delay by a customer, manufacturing,
technical, reliability or other difficulties, including difficulties relating
to customization and reconfiguration of systems, a delay in the supply of
components, subassemblies or services or a delay due to competitive or
economic factors, may cause net sales in a particular period to fall
significantly below the Company's expectations, which could have a material
adverse effect upon the Company's business, financial condition or results of
operations. The relatively long manufacturing cycle of many of its testers has
caused and could continue to cause future shipments of such products to be
delayed from one quarter to the next, which could materially adversely affect
the Company's business, financial condition or results of operations.
Furthermore, announcements by the Company or its competitors of new products
and technologies could cause customers to defer or cancel purchases of the
Company's existing systems, which could also have a material adverse effect on
the Company's business, financial condition or results of operations. The
impact of these and other factors on the Company's sales and operating results
in any future period cannot be forecasted with certainty. In addition, the
need for continued significant expenditures for research and development,
marketing and other expenses for new products, capital equipment purchases and
worldwide training and customer service and support, among other factors, will
make it difficult for the Company to reduce its significant fixed expenses in
a particular period if the Company's net sales goals for such period are not
met. Accordingly, there can be no assurance that the Company will be able to
be profitable or that it will not again sustain losses in future periods. Due
to all of the foregoing factors, it is likely that in some future quarter the
Company's operating results will be below the expectations of public market
analysts and investors, as they were in the first and second quarters of 1997.
In such event, the price of the Company's Common Stock may be materially
adversely affected.
 
Cyclicality of Semiconductor Industry
 
  The Company's business and results of operations depend in significant part
upon the capital expenditures of manufacturers of semiconductors and companies
which specialize in contract packaging and/or testing of semiconductors,
including manufacturers and contractors that are opening new or expanding
existing fabrication facilities, or upgrading existing equipment, which in
turn depend upon the current and anticipated market demand for semiconductors
and products incorporating semiconductors. Historically and recently, the
semiconductor industry has been highly cyclical with recurring periods of
oversupply, which often have had a severe effect on the semiconductor
industry's demand for test equipment, including the systems manufactured and
marketed by the Company. The Company believes that the markets for newer
generations of semiconductors will also be subject to similar fluctuations.
The Company has in the past, and during the last twelve months in particular,
experienced shipment delays, delays in commitments and purchase order
restructurings by several of its customers and anticipates that this may
continue to occur in the future. Accordingly, the Company can give no
assurance that it will be able to achieve or maintain its current or prior
level of sales or rate of growth. During the last four quarters, including the
third quarter of 1997, the Company's net sales, gross margins and net income
have been significantly below the net sales, gross margins and net income,
respectively, of the comparable prior year's quarterly results. The Company
anticipates that a significant portion of new orders may depend upon demand
from semiconductor device manufacturers building or expanding fabrication
facilities and new device testing requirements that are not addressable by
currently installed test equipment, and there can be no assurance that such
demand will develop to a significant degree, or at all. In addition, any
factor adversely affecting the semiconductor industry or particular segments
within the semiconductor industry may adversely affect the Company's business,
financial condition or results of operations. Therefore, there can be no
assurance that the Company's operating results will not continue to be
materially adversely affected if downturns or slowdowns in the semiconductor
industry continue or occur again in the future.
 
Management of Fluctuations in Operating Results
 
  The Company has over the last several years experienced significant
fluctuations in its operating results. Since 1993, the Company has overall
significantly increased the scale of its operations to support increased sales
 
                                      12
<PAGE>
 
levels and has expanded its operations to address critical infrastructure and
other requirements, including the hiring of additional personnel, significant
investments in research and development to support product development, the
March 1995 acquisition of EPRO, the Company's establishment of a joint venture
with Innotech, Inc., the Company's acquisition in July 1997 of the assets and
certain liabilities of TSSI and the Company's acquisition in August of 1997 of
a software product line from Zycad. However, the Company has during certain
historical periods, particularly over the past twelve months, experienced
revenue declines and reductions in its operations.
 
  Fluctuations in the Company's sales and operations have placed a
considerable strain on its management, financial, manufacturing and other
resources. In order to effectively deal with the changes brought on by the
cyclical nature of the industry, the Company has been required to implement
and improve a variety of highly flexible operating, financial and other
systems, procedures and controls capable of expanding or contracting
consistent with the Company's business. There can be no assurance that any
existing or new systems, procedures or controls will be adequate to support
fluctuations in the Company's operations or that its systems, procedures and
controls will be designed, implemented or improved in a cost effective and
timely manner. Any failure to implement, improve and expand or contract such
systems, procedures and controls in an efficient manner at a pace consistent
with the Company's business could have a material adverse effect on the
Company's business, financial condition or results of operations.
 
Expansion of Operations
 
  Currently, the Company is devoting significant resources to the development
of new products and technologies. During 1997, the Company will conduct
evaluations of these products and will continue to invest significant
additional resources in plant and equipment, inventory, personnel and other
costs, to begin production of these products and to provide the marketing,
administration and after-sales service and support, if any, required to
service and support these new products. Accordingly, there can be no assurance
that gross profit margin and inventory levels will not be adversely impacted
in the future by start-up costs associated with the initial production and
installation of these new product lines. These start-up costs include, but are
not limited to, additional manufacturing overhead, additional inventory and
warranty reserve requirements and the creation of after-sales service and
support organizations. Additionally, there can be no assurance that operating
expenses will not increase, relative to sales, as a result of adding
additional marketing and administrative personnel, among other costs, to
support the Company's additional products. If the Company is unable to achieve
significantly increased net sales or its sales fall below expectations, the
Company's operating results will be materially adversely affected. There can
be no assurance that net sales will increase or remain at recent levels or
that such products will be successfully commercialized.
 
Limited Sources of Supply; Reliance on Subcontractors
 
  Certain components, subassemblies and services necessary for the manufacture
of the Company's testers are obtained from a limited group of suppliers. The
Company does not maintain any long-term supply agreements with any of its
vendors and purchases its components and subassemblies through individual
purchase orders. The manufacture of certain of the Company's components and
subassemblies is an extremely complex process. The Company also relies on
outside vendors to manufacture certain components and subassemblies and to
provide certain services. In addition, the Company and certain of its
subcontractors periodically experience significant shortages and delays in
delivery of various components and subassemblies. There can be no assurance
that these or other problems will not continue to occur in the future with
these or the Company's other suppliers or outside subcontractors. The
Company's reliance on a limited group of suppliers and the Company's reliance
on outside subcontractors involve several risks, including an inability to
obtain an adequate supply of required components, subassemblies and services
and reduced control over the price, timely delivery, reliability and quality
of components, subassemblies and services. Shortages, delays, disruptions or
terminations of the sources for these components and subassemblies has delayed
and could continue to delay shipments of the Company's systems and could have
a material adverse effect on the Company's business, financial condition or
results of operations. Any continuing inability to obtain adequate yields or
timely deliveries or any other circumstance that would
 
                                      13
<PAGE>
 
require the Company to seek alternative sources of supply or to manufacture
such components internally could have a material adverse effect on the
Company's business, financial condition or results of operations. Such delays,
shortages and disruptions would also damage relationships with current and
prospective customers and could allow competitors to penetrate such customer
accounts. There can be no assurance that the Company's internal manufacturing
capacity and that of its suppliers and subcontractors will be sufficient to
meet customer requirements.
 
Highly Competitive Industry
 
  The ATE industry is intensely competitive. Because of the substantial
investment required to develop test application software and interfaces, the
Company believes that once a semiconductor manufacturer has selected a
particular ATE vendor's tester, the semiconductor manufacturer is likely to
use that tester for a majority of its testing requirements for the market life
of that semiconductor and, to the extent possible, subsequent generations of
similar products. As a result, once an ATE customer chooses a system for the
testing of a particular device, it is difficult for competing vendors to
achieve significant ATE sales to such customer for similar use. The inability
of the Company to achieve significant sales to any ATE customer could have a
material adverse effect on the Company's business, financial condition or
results of operations.
 
  The Company faces substantial competition throughout the world, primarily
from ATE manufacturers located in the United States, Europe and Japan, as well
as several of the Company's customers. Many of the Company's competitors have
substantially greater financial and other resources with which to pursue
engineering, manufacturing, marketing and distribution of their products.
Certain of the Company's competitors have recently introduced or announced new
products with certain performance or price characteristics equal or superior
to certain products currently offered by the Company. The Company believes
that if the ATE industry continues to consolidate through strategic alliances
or acquisitions, the Company will continue to face significant additional
competition from larger competitors that may offer more complete product lines
and services than the Company. The Company's competitors are continuing to
improve the performance of their current products and to introduce new
products, enhancements and new technologies that provide improved cost of
ownership and performance characteristics. New product introductions by the
Company's competitors could continue to cause a decline in sales or loss of
market acceptance of the Company's existing products. Moreover, increased
competitive pressure could continue to lead to intensified price-based
competition, which could materially adversely affect the Company's business,
financial condition or results of operations. The Company has experienced and
continues to experience significant price competition in the sale of all of
its testers. In addition, at the end of a product life cycle and as
competitors introduce more technologically advanced products, pricing
pressures typically become more intense. The Company believes that to be
competitive, it will continue to require significant financial resources in
order to, among other items, invest in new product development and
enhancements and to maintain customer service and support centers worldwide.
There can be no assurance that the Company will be able to compete
successfully in the future.
 
Rapid Technological Change; Importance of Timely Product Introduction
 
  The ATE market is subject to rapid technological change and new product
introductions and enhancements and related software tools. The Company's
ability to be competitive in this market will depend in significant part upon
its ability to successfully develop and introduce new products and
enhancements and related software tools with greater features on a timely and
cost-effective basis, including the products under development acquired in the
EPRO merger and the TSSI and Zycad product line acquisitions. The Company's
customers require testers with additional features and higher performance and
other capabilities. The Company is therefore required to enhance the
performance and other capabilities of its existing systems and related
software tools. Any success by the Company in developing new and enhanced
systems and related software tools and new features to its existing systems
depends upon a variety of factors, including product selection, timely and
efficient completion of product design, timely and efficient implementation of
manufacturing and assembly processes, product performance and reliability in
the field and effective sales and marketing. Because new product development
 
                                      14
<PAGE>
 
commitments must be made well in advance of sales, new product decisions must
anticipate both future demand and the availability of technology to satisfy
that demand. There can be no assurance that the Company will be successful in
selecting, developing, manufacturing and marketing new products or
enhancements and related software tools. The inability of the Company to
introduce new products and related software tools that contribute
significantly to net sales, gross margins and net income would have a material
adverse effect on the Company's business, financial condition or results of
operations. New product or technology introductions by the Company's
competitors could cause a decline in sales or loss of market acceptance of the
Company's existing products. In addition, new product introductions by the
Company may cause confusion among the Company's customers if they transition
to such new products, and may delay product purchases.
 
  Significant delays can occur between a system's introduction and the
commencement by the Company of volume production of such system. The Company
has been and is experiencing significant delays in the introduction, volume
production and sales of its systems and related feature enhancements,
including new models within the digital, mixed-signal and non-volatile memory
product lines, due to technical, manufacturing, parts shortages, component
reliability and other difficulties and may continue to experience similar
delays in the future. As a result, certain of the Company's significant
customers have experienced significant delays in receiving and using certain
of the Company's testers in production. There can be no assurance that these
or additional difficulties will not continue to arise in the future with
respect to the Company's systems or that such delays will not materially
adversely affect customer relationships and future sales. Moreover, there can
be no assurance that the Company will not encounter these or other
difficulties that could delay future introductions or volume production or
sales of its systems or enhancements and related software tools. The Company
has incurred and may continue to incur substantial unanticipated costs to
ensure the functionality and reliability of its testers and to increase
feature sets. If the Company's systems continue to have reliability, quality
or other problems, or the market perceives certain of the Company's products
to be feature deficient, reduced orders, higher manufacturing costs, delays in
collecting accounts receivable and higher service, support and warranty
expenses, or inventory write-offs, among other items, could result. The
Company's failure to have a competitive tester and related software tools
available when required by a semiconductor manufacturer could make it
substantially more difficult for the Company to sell testers to that
manufacturer for a number of years. The Company believes that the continued
acceptance, volume production, timely delivery and customer satisfaction of
its newer digital, mixed signal and non-volatile memory testers are of
critical importance to its future financial results. As a result, an inability
to correct any technical, reliability, parts shortages or other difficulties
associated with the Company's systems or to manufacture and ship the Company's
systems on a timely basis to meet customer requirements could damage
relationships with current and prospective customers and would materially
adversely affect the Company's business, financial condition or results of
operations.
 
Customer Concentration; Lengthy Sales Cycle
 
  During the nine months ended July 31, 1997, three customers accounted for
22%, 12% and 9%, respectively, of the Company's net sales. One customer (a
distributor) accounted for 25%, 17% and 13% of the Company's net sales in
fiscal 1996, 1995 and 1994, respectively. The loss of or any reduction in
orders by a significant customer, including losses or reductions due to
continuing or other technical, manufacturing, reliability or other
difficulties associated with the Company's products or market, economic or
competitive conditions in the semiconductor industry or in other industries
that manufacture products utilizing semiconductors could materially adversely
affect the Company's business, financial condition or results of operations.
The Company's ability to maintain or increase its sales levels in the future
will depend in significant part upon its ability to obtain orders from
existing and new customers and to manufacture systems on a timely and cost-
effective basis, the financial condition and success of its customers, general
economic conditions, and the Company's ability to meet increasingly stringent
customer performance and other requirements and shipment delivery dates. There
can be no assurance that the Company will be able to maintain or increase the
level of its net sales in the future or that the Company will be able to
retain existing customers or attract new ones.
 
  Sales of the Company's systems depend in significant part upon the decision
of a semiconductor manufacturer to develop and manufacture new semiconductor
devices or to increase manufacturing capacity. As
 
                                      15
<PAGE>
 
a result, sales of the Company's testers are subject to a variety of factors
outside of the Company's control. In addition, the decision to purchase a
tester generally involves a significant commitment of capital, with the
attendant delays frequently associated with significant capital expenditures.
For these and other reasons, the Company's systems have lengthy sales cycles
during which the Company may expend substantial funds and management effort to
secure a sale and subject the Company to a number of significant risks.
 
Acquisitions
 
  The Company has developed in significant part through mergers and
acquisitions of other companies and businesses. Prior to its initial public
offering in 1993, the Company acquired two companies and the semiconductor
test systems division of Tektronix, Inc. In 1995, the Company acquired EPRO, a
memory tester company. In July 1997, the Company acquired the TDS assets of
Summit Design, Inc. and, in August 1997, acquired the TDX fault simulation and
test program development products from Zycad. The Company intends in the
future to pursue additional acquisitions of complementary product lines,
technologies and businesses. Any future acquisitions by the Company, if any,
could result in potentially dilutive issuances of equity securities, the
incurrence of debt and contingent liabilities, expenditures and reserves, and
amortization expenses related to goodwill and other intangible assets, which
could materially adversely affect the Company's business, financial condition
or results of operations. The Company's one-time charge for in-process
research and development for the TSSI asset acquisition accounted for the
Company's net loss for the third quarter of 1997. In addition, acquisitions
involve numerous other risks, including difficulties in the assimilation of
the operations, technologies and products of the acquired companies, the
diversion of management's attention from other business concerns, risks of
entering markets in which the Company has no or limited direct prior
experience, and the potential loss of key employees of the acquired company.
From time to time, the Company has engaged in and will continue to engage in
discussions with third parties concerning potential acquisitions of product
lines, technologies and businesses. In the event that such an acquisition does
occur, however, there can be no assurance as to the effect thereof on the
Company's business, financial condition or results of operations.
 
Dependence on Key Personnel
 
  The Company's future operating results depend in significant part upon the
continued service of its key personnel, none of whom are bound by an
employment or non-competition agreement. The Company's future operating
results also depend in significant part upon its ability to attract and retain
qualified management, manufacturing, technical, engineering and marketing and
sales and support personnel. Competition for such personnel is intense, and
there can be no assurance that the Company will be successful in attracting or
retaining such personnel. There may be only a limited number of persons with
the requisite skills to serve in these positions and it may be increasingly
difficult for the Company to hire such personnel over time. The loss of any
key employee, the failure of any key employee to perform in his or her current
position, or the Company's inability to attract and retain skilled employees,
as needed, could materially adversely affect the Company's business, financial
condition or results of operations.
 
  Recently, the Company has experienced an increased level of employee
turnover. The Company believes that this increase is due to several factors,
including the recent semiconductor industry slowdown; an expanding economy
within the geographic area where the Company maintains its principal business
offices, making it more difficult for the Company to retain its employees; and
the declining value of stock options granted to employees, relative to their
total compensation, as a result of full vesting of options granted prior to
the Company's initial public offering. Due to these and other factors, the
Company may continue to experience high levels of employee turnover, which
could materially adversely impact the Company's business, financial condition
and results of operations.
 
International Sales
 
  International sales accounted for approximately 70%, 67% and 55% of total
net sales for the first nine months of fiscal 1997, and for fiscal years 1996
and 1995, respectively. The Company is also attempting to
 
                                      16
<PAGE>
 
increase its sales to non-U.S.-based customers. As a result, the Company
anticipates that international sales will continue to account for a
significant portion of total net sales in the foreseeable future. These
international sales will continue to be subject to certain risks, including
changes in regulatory requirements, tariffs and other barriers, political and
economic instability, an outbreak of hostilities, integration of foreign
operations of acquired businesses, foreign currency exchange rate
fluctuations, difficulties with distributors, joint venture partners, original
equipment manufacturers, foreign subsidiaries and branch operations,
potentially adverse tax consequences and the possibility of difficulty in
accounts receivable collection. The Company is also subject to the risks
associated with the imposition of legislation and regulations relating to the
import or export of semiconductor equipment. The Company cannot predict
whether quotas, duties, taxes or other charges or restrictions will be
implemented by the United States or any other country upon the importation or
exportation of the Company's products in the future. Any of these factors or
the adoption of restrictive policies could have a material adverse effect on
the Company's business, financial condition or results of operations.
 
Proprietary Rights
 
  The Company attempts to protect its intellectual property rights through
patents, copyrights, trade secrets and other measures, including
confidentiality agreements. There can be no assurance that others will not
independently develop substantially equivalent proprietary information and
techniques or otherwise gain access to the Company's trade secrets and other
intellectual property rights or disclose such technology or that the Company
can meaningfully protect its trade secrets or other intellectual property
rights. There can be no assurance that patents owned by the Company will not
be invalidated, deemed unenforceable, circumvented or challenged, or that the
rights granted thereunder will provide competitive advantages to the Company
or that any of the Company's pending or future patent applications will be
issued with claims of the scope sought by the Company, if at all. Furthermore,
there can be no assurance that others will not develop similar products,
duplicate the Company's products or design around the patents owned by the
Company. In addition, there can be no assurance that foreign intellectual
property laws or the Company's agreements will protect the Company's
intellectual property rights. Failure to protect the Company's intellectual
property rights could have a material adverse effect upon the Company's
business, financial condition or results of operations. The Company has been
involved in extensive, expensive and time-consuming reviews of, and litigation
concerning, patent infringement claims. In addition, the Company has at times
been notified of other claims that it may be infringing intellectual property
rights possessed by third parties and expects to continue to receive notice of
such claims in the future.
 
  The European patent application relating to one of the proprietary CMOS
stabilization methods owned by the Company was abandoned by the prior owner
after the European patent examiner cited prior art. This prior art was not
referenced in the corresponding United States patent application. Based upon
its review to date of the cited prior art and the European examiner's
objections, and in part upon the advice of Smith-Hill and Bedell, P.C.,
outside patent counsel to the Company ("SHB"), the Company believes that such
prior art is unlikely to affect the validity or scope of the claims of the
United States issued patent.
 
  This prior art may, however, render invalid or significantly narrow the
scope of certain claims set forth in the United States patent covering the
Company's other proprietary CMOS stabilization method. The European examiner
referred to this prior art in the corresponding European patent application.
The European application was approved, but with narrower claims than the
United States patent. This prior art was not referenced in the corresponding
United States patent. Based in part upon the advice of SHB, and on the
Company's review of its current products, the Company believes that this
patent will continue to be valuable to the Company in preventing imitation of
the Company's products covered by this patent. Additionally, in mid-1992, a
third party suggested that certain claims set forth in this patent might be
invalid as a result of other alleged prior art. The Company believes, based in
part upon the advice of SHB, that the prior art alleged by the third party is
less relevant than the prior art referenced by the European examiner. However,
there can be no assurance that any of the aforementioned prior art or other
prior art will not be successfully asserted and used to invalidate or narrow
the scope of any claim of the United States patents or any other patents or
other patent applications of the Company.
 
                                      17
<PAGE>
 
  Certain of the Company's customers have received notices of infringement
from Jerome Lemelson alleging that the manufacture of semiconductor products
and/or the equipment used to manufacture semiconductor products infringes
certain patents issued to such person. The Company was notified by a customer
in 1990 and a different customer in late 1994 that the Company may be
obligated to defend or settle claims that the Company's products infringe such
person's patents, and, in the event it is subsequently determined that the
customer infringes such person's patents, such customer intends to seek
reimbursement from the Company for damages and other related expenses. There
can be no assurance that the Company will be successful in defending current
or future patent infringement claims or claims for indemnification resulting
from infringement claims. An award of damages, injunctive relief or
expenditures by the Company of significant amounts in defending any such
action could materially adversely affect the Company's business, financial
condition or results of operations, regardless of the outcome of any
litigation. With respect to any claims, the Company may seek to obtain a
license under the third party's intellectual property rights. There can be no
assurance, however, that a license will be available on reasonable terms or at
all. The Company could decide, in the alternative, to continue to resort to
litigation to challenge such claims. Such challenges have been and could
continue to be extremely expensive and time consuming, and could materially
adversely affect the Company's business, financial condition or results of
operations, regardless of the outcome of any litigation.
 
Future Capital Needs
 
  The development and manufacture of new ATE systems and enhancements are
highly capital intensive. In order to be competitive, the Company must make
significant investments in capital equipment, expansion of operations,
systems, procedures and controls, research and development and worldwide
training, customer service and support, among many items. The Company expects
that cash on hand and cash equivalents, including restricted cash, proceeds
from the $100 million private placement, short-term investments, funds
available under its bank line of credit, anticipated cash flow from operations
and equipment lease arrangements will satisfy its financing requirements for
at least the next 18 months.
 
Volatility of Stock Price
 
  The Company believes that factors such as announcements of developments
related to the Company's business, fluctuations in the Company's financial
results, general conditions or developments in the semiconductor and capital
equipment industry and the general economy, sales of the Company's Common
Stock into the marketplace, an outbreak of hostilities, natural disasters,
announcements of technological innovations or new products or enhancements by
the Company or its competitors, developments in patents or other intellectual
property rights, developments in the Company's relationships with its
customers and suppliers, or a shortfall or changes in revenue, gross margins
or earnings or other financial results from analysts' expectations could cause
the price of the Company's Common Stock to fluctuate, perhaps substantially.
In recent years the stock market in general, and the market for shares of
small capitalization stocks in particular, including the Company, have
experienced extreme price fluctuations, which have often been unrelated to the
operating performance of affected companies. There can be no assurance that
the market price of the Company's Common Stock will not continue to experience
significant fluctuations in the future, including fluctuations that are
unrelated to the Company's performance.
 
Leverage
 
  In connection with the sale of the $100 million aggregate principal amount
of the Note due 2002, the Company will incur $100 million of indebtedness
which will result in a ratio of long-term debt to total capitalization at July
31, 1997 of approximately 34% on an as-adjusted basis. As a result of this
indebtedness, the Company's principal and interest obligations will increase
substantially. The degree to which the Company will be leveraged could
materially adversely affect Company's ability to obtain financing for working
capital, acquisitions or other purposes and could make it more vulnerable to
industry downturns and competitive pressures. The Company's ability to meet
its debt service obligations will be dependent upon the Company's
 
                                      18
<PAGE>
 
future performance, which will be subject to financial, business and other
factors affecting the operations of the Company, many of which are beyond its
control.
 
Effects of Certain Anti-Takeover Provisions
 
  Certain provisions of the Company's Certificate of Incorporation, equity
incentive plans, Bylaws and Delaware law may discourage certain transactions
involving a change in control of the Company. In addition to the foregoing,
the Company's classified board of directors, the shareholdings of the
Company's officers, directors and persons or entities that may be deemed
affiliates and the ability of the Board of Directors to issue "blank check"
preferred stock without further stockholder approval could have the effect of
delaying, deferring or preventing a change in control of the Company and may
adversely affect the voting and other rights of holders of Common Stock.

ITEM 5. OTHER INFORMATION
 
  On July 11, 1997, the Company, through its newly formed subsidiary, Test
Systems Strategies, Inc., a Delaware Corporation ("TSSI"), acquired certain
assets and assumed certain liabilities from Summit Design, Inc. and its wholly
owned subsidiary, Test Systems Strategies, Inc., an Oregon Corporation,
including the test development series software ("TDS") and TSSI trademark of
Test Systems Strategies, Inc. (an Oregon Corporation). TDS includes tools
designed to convert gate-level simulation data from electronic design
automation simulators to programs that operate on targeted automatic test
equipment ("ATE") for testing integrated circuits characterized by the gate-
level simulation data. TDS facilitates simulation analysis, stimulus
generation, simulation rules checking, tester resource checking, ATE test
program generation, and test program conversion. The acquisition has been
accounted for by the Company under the purchase method of accounting, and
accordingly, the condensed consolidated financial statements reflect the
impact of TDS operations subsequent to the acquisition date.
 
  The purchase price of $7.3 million, consisted of a cash payment of $7.0
million to Summit Design, Inc. and $300,000 for the assumption of liabilities.
Acquired assets and liabilities were recorded at their estimated fair market
value at the date of the acquisition. The aggregate purchase price, plus
related acquisition expenses, have been allocated to the assets and
liabilities acquired based on valuations. Amounts allocated to in-process
research and development of approximately $6.0 million were written-off at the
acquisition date, representing an estimated value (using risk-adjusted cash
flows, discounted at 35%) of development programs that have not yet reached
technological feasibility. Amounts allocated to developed technology, $1.0
million and workforce in place, $0.3 million, are being amortized on a
straight line basis over periods of six and three years respectively.
 
  In addition, on May 19, 1997, the Company entered into an agreement with
Summit Design, Inc. for the Company to purchase approximately $18 million of
Summit's Visual Testbench ("VTB") product licenses and maintenance services
through 1999.
 
  On August 20, 1997, the Company, through one of its subsidiaries, Test
Systems Strategies, Inc., purchased from Zycad Corporation and one of its
subsidiaries, Attest Software, Inc. certain assets and assumed certain
liabilities for $2,250,000.
 
  On September 10, 1997, the Company sold $100 million of 5 1/4% convertible
subordinated notes (the "Notes") due 2002 through a private placement within
the U.S. to qualified institutional buyers in accordance with Rule 144A and
outside the U.S., to non-U.S. persons as defined in Regulation S under the
Securities Act of 1933, as amended. The Notes are convertible into common
stock of the Company at a conversion price of $69.15 per share. The Company
has granted to Smith Barney, Inc., the initial purchaser, a 30-day option to
purchase an
 
                                      20
<PAGE>
 
additional $15 million of Notes to cover over-allotments, if any. Expense of
$3.0 million associated with the offering will be deferred and included in
other assets. Such expenses will be amortized to interest expense over the term
of the Notes.

                            ASSET PURCHASE AGREEMENT


     This ASSET PURCHASE AGREEMENT (the "Agreement") is made and entered into as
of May 19, 1997 by and among Credence Systems Corporation, a Delaware
corporation ("CSC"), Test Systems Strategies, Inc., a Delaware corporation and
wholly-owned subsidiary of CSC ("Buyer"), Summit Design, Inc., a Delaware
corporation ("Summit"), and Test Systems Strategies, Inc., an Oregon corporation
and wholly-owned subsidiary of Summit ("Seller").

                                    RECITALS

     A.  The Boards of Directors of each of Summit, Seller, CSC and Buyer
believe it is in the best interests of each company and their respective
securityholders that Buyer acquire certain listed assets and assume certain
listed liabilities of Seller (the "Acquisition").

     B.  On the date hereof, Buyer has executed a $2,000,000 irrevocable
purchase order to purchase 400 time-based licenses for Summit's Visual HDL
interfaces for Visual Testbench ("VTB") software on CSC's standard form of
purchase order, which is payable within five (5) business days after the date
hereof.

     NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
the parties agree as follows:


                                   ARTICLE I

                                THE ACQUISITION

     1.1 PURCHASE OF ASSETS.

         (a) PURCHASE AND SALE OF ASSETS.  On the terms and subject to the
conditions set forth in this Agreement, Seller will sell, convey, transfer,
assign and deliver to Buyer and Buyer will purchase and acquire from Seller on
the Closing Date (as defined in Section 1.3(a)), all of Seller's right, title
and interest in and to the assets and properties of Seller set forth on Schedule
1.1(a) (collectively, the "Assets") free and clear of all liens, pledges,
charges, claims, actions, suits, proceedings, security interests or other
encumbrances of any sort ("Liens"), other than as set forth on Schedule 2.7. The
Assets do not include Summit's and Seller's VTB software.

         (b) NONASSIGNMENT OR SUBCONTRACTING OF CERTAIN ASSETS.
Notwithstanding anything to the contrary in this Agreement, to the extent that
the assignment or subcontracting hereunder of any of the Assets shall require
the consent of any other party (or in the event that any of the same shall be
nonassignable or unable to be subcontracted), neither this Agreement nor any
action taken pursuant to its provisions shall constitute an assignment or
subcontract or an agreement to assign or subcontract if such assignment or
subcontract or attempted assignment or subcontract would constitute a breach
thereof or result in the loss or diminution thereof; PROVIDED, HOWEVER, that in
each such case, Seller shall use its commercially reasonable efforts to obtain
the consent of such other party to an assignment to Buyer.  If such consent is
not obtained by the Closing, Seller shall cooperate with Buyer in any
arrangement designed for Buyer to perform Seller's obligation with respect to
such
<PAGE>
 
Asset after the Closing and for Buyer to receive the benefits under any such
Asset after the Closing, which arrangements may include enforcement, for the
account and benefit of Buyer, of any and all rights of Seller against any other
person arising out of the breach or cancellation by such other person or
otherwise, all of such actions of Seller to be at the direction and expense of
Buyer.  Seller shall reimburse or pay Buyer for a portion equal to one-half of
all costs and expenses, including amounts owed as a result of increased
obligations under such instruments, resulting from an inability of Buyer to
receive the benefits of such assignment or subcontract.

         (c) ASSUMPTION OF LIABILITIES.  At the Closing, Buyer shall only assume
the obligations and liabilities of Seller listed on Schedule 1.1(c) (the
"Assumed Liabilities").  Buyer shall not assume any liabilities or obligations
of Seller or the Assets except for those liabilities and obligations which Buyer
expressly assumes pursuant to this Section 1.1(c) and Seller shall retain those
liabilities of Seller that are not Assumed Liabilities.  Other than the Assumed
Liabilities of Seller specifically listed in Schedule 1.1(c), Buyer shall not
assume, nor shall Buyer or CSC or any of their respective affiliates, directors,
employees, stockholders or agents, be deemed to have assumed or guaranteed, or
be responsible for in any way, any liabilities or obligations, whether such
liabilities or obligations are contingent or otherwise, or direct or indirect,
of Seller or Summit.

         (d) RISK OF LOSS.  In the event any of the Assets are unavailable for
delivery to Buyer on the Closing Date as a result of risks for which such Assets
were insured by Seller, Buyer may at its option elect (i) to require Seller to
deliver to Buyer assignments of such Seller's rights under its insurance
policies, if any, applicable to such Assets and to close on that basis, or (ii)
to not close due to the failure of a condition to closing if the rights
described in (i) above are not fully assignable and the amount of the loss
reasonably can be expected to be in excess of five hundred thousand dollars
($500,000).  Seller hereby agrees to use its reasonable best efforts to make
such assignment of rights if Buyer so elects.

     1.2 CONSIDERATION.

         (a) CONSIDERATION.  On the terms and subject to the conditions set
forth in this Agreement, Buyer shall on the Closing Date pay to Seller by wire
transfer of immediately available funds the sum of five million dollars
($5,000,000) in full payment for the transfer of Assets to Buyer and the
assumption of the Assumed Liabilities by Buyer (the "Purchase Price").

         (b) TRANSFER TAXES.  Buyer and Seller shall each pay and promptly
discharge when due one-half of the entire amount of any and all sales, transfer
and use taxes ("Sales Taxes") imposed or levied by reason of the sale of the
Assets to the Buyer.  The parties shall cooperate with each other to the extent
reasonably requested and legally permitted to minimize any such Sales Taxes and
to prepare any documents necessary to satisfy the requirements of any applicable
exemption from such laws.  Buyer shall take title to, and possession of, the
Assets in the State of Oregon.  Buyer and Seller hereby waive compliance with
the Oregon Uniform Commercial Code-Bulk Transfers and any other applicable state
bulk transfer laws.  Seller agrees to indemnify Buyer and CSC against all claims
(other than Assumed Liabilities) brought by a creditor of Seller or Summit
against Buyer or CSC or the Assets based on noncompliance with such laws in
connection with the sale of the Assets.

     1.3 CLOSING.

         (a) CLOSING.  Unless this Agreement is earlier terminated pursuant to
Section 8.1, the closing of the transactions contemplated by this Agreement (the
"Closing") shall be held at the offices of Summit, 9305 S.W. Gemini Drive,
Beaverton, Oregon, at 10:00 a.m. on the later of (i) the date which is two
business days following satisfaction or waiver of the last of the conditions to
Closing as set forth in
<PAGE>
 
Article VI hereof, and (ii) July 1, 1997, or on such other time and/or date as
the parties agree (the actual date on which the Closing occurs is referred to
herein as the "Closing Date").

         (b)  DELIVERY.  At the Closing:

            (i)   Buyer shall deliver to Seller:

                   (A) an instrument of assumption of liabilities by which Buyer
         shall assume the Assumed Liabilities as of the Closing;

                   (B) the Purchase Price; and

                   (C) the Software OEM License Agreement and the Software
         Development Agreement (the "Related Agreements").

            (ii)  Seller and Summit shall deliver to Buyer:

                   (A) a good and sufficient bill of sale for the Assets,
         selling, delivering, transferring and assigning to Buyer title to all
         of Seller's and/or Summit's right, title and interest in and to the
         Assets, free and clear of all Liens;

                   (B) the Related Agreements;

                   (C) valid assignments for all Contracts (as defined below)
         and all other contracts and agreements under which obligations are owed
         to Seller or Summit with respect to the Assets and intellectual
         property forms for filing with the applicable governmental agencies and
         other third party or governmental consents necessary to transfer the
         Assets; and

                   (D) resale certificates for the resale of any items in
         inventory.

            (iii) Seller and Buyer shall deliver or cause to be delivered to one
another such other instruments and documents necessary or appropriate to
evidence the due execution, delivery and performance of this Agreement.

         (c) TAKING OF NECESSARY ACTION; FURTHER ACTION.  If, at any time after
the Closing Date and at Buyer's request, any further action is necessary or
desirable to carry out the purposes of this Agreement and to vest the Buyer with
full right, title and possession to the Assets, Seller and Summit shall, and
shall use their reasonable best efforts to cause Seller's employees, agents and
consultants to, sign, execute and acknowledge any and all documents and to
perform such acts as may be necessary for the purposes of perfecting the
assignment to Buyer of the Assets.  The costs related to any of the foregoing
shall be shared equally by Seller and Buyer.

                                   ARTICLE II
              REPRESENTATIONS AND WARRANTIES OF SELLER AND SUMMIT

     Summit and Seller, jointly and severally, represent and warrant to Buyer
and CSC, subject to such exceptions as are specifically disclosed in the
disclosure schedules supplied by Seller to Buyer and CSC (the "Seller
Schedules") and dated as of the date hereof, which disclosures shall be deemed
to be representations and warranties hereunder, as follows:
<PAGE>
 
     2.1 ORGANIZATION; GOOD STANDING.  Each of Seller and Summit are
corporations duly organized, validly existing and in good standing under the
laws of their respective states of organization, and have the corporate power
and authority to own, lease and operate their properties and to carry on their
businesses as the same are now being conducted.  Each of Seller and Summit is
qualified as a foreign corporation and is in good standing in each jurisdiction
in which the failure to be so qualified would have a material adverse effect on
the Assets (or Buyer's interest therein or use thereof following the Closing) (a
"Material Adverse Effect").  Seller has property, employees or operations
relating to the Assets only in the jurisdictions set forth on Schedule 2.1.
Summit owns one hundred percent (100%) of the shares of capital stock or other
proprietary interests in Seller.

     2.2 AUTHORIZATION OF SELLER.  Each of Seller and Summit has full power and
authority to enter into this Agreement and the Related Agreements to which it is
a party, to perform its obligations hereunder and thereunder, and to consummate
the transactions contemplated hereby and thereby, including, without limitation,
the execution and delivery of this Agreement, general conveyances, bills of
sale, assignments, and other documents and instruments evidencing the conveyance
of the Assets or delivered in accordance with Sections 1.1(b) or 1.3(b)
hereunder (the "Closing Documents") and the Related Agreements to which it is a
party.  Each of Seller and Summit has taken all necessary and appropriate
corporate action with respect to the execution and delivery of this Agreement,
the Closing Documents, and the Related Agreements to which it is a party.  No
other corporate or securityholder proceedings or action on the part of Seller or
Summit, or their respective securityholders, are necessary to authorize this
Agreement and the Related Agreements or to consummate the transactions
contemplated hereby and thereby.  This Agreement and the Related Agreements have
been duly executed and delivered by Seller and Summit.  This Agreement and the
Related Agreements to which it is a party constitute valid and binding
obligations of Seller and Summit, enforceable in accordance with their terms:
(i) except as limited by applicable bankruptcy, insolvency, moratorium,
reorganization, or other laws affecting creditors' rights and remedies
generally, (ii) except as may be required by the Bulk Sales provisions of
applicable state law, and (iii) except as the indemnification provisions
contained in this Agreement may be limited by principles of public policy.  The
execution and delivery of this Agreement and the Related Agreements by Seller
and Summit do not, and, as of the Closing, the consummation of the transactions
contemplated hereby and thereby will not, conflict with, or result in any
violation of, or default under (with or without notice or lapse of time, or
both), or give rise to a right of termination, cancellation or acceleration of
any obligation or loss of any benefit under (any such event, a "Conflict") (i)
any provision of the Articles or Certificate of Incorporation or Bylaws of
Seller or Summit or (ii) any material mortgage, indenture, lease, contract or
other agreement or material instrument, permit, concession, franchise, license,
judgment, order, decree, statute, law, ordinance, rule or regulation applicable
to Seller or Summit or their properties or assets, except where such Conflict
would not have a Material Adverse Effect.

     2.3 FINANCIAL STATEMENTS.  Seller has previously furnished Buyer with
copies of the profit and loss statements of Seller for each of the quarters in
the year ended December 31, 1996 and the quarter ended March 31, 1997,
(collectively, the "Seller Financials").  The Seller Financials fairly present'
in all material respects the results of operations of Seller for the periods
therein set forth, subject to normal year-end adjustments, in each case in
accordance with generally accepted accounting principles applied on a consistent
basis.  Summit's revenue recognition policies with respect to the Seller
Financials have been made in accordance with generally accepted accounting
principles.  Summit and Seller maintain an accounting system in accordance with
generally accepted accounting principles.  Notwithstanding the foregoing, the
Seller Financials were prepared using an allocation of cost of goods sold based
on Summit's overall cost of goods sold as a percentage of total revenue, using
an allocation of
<PAGE>
 
general and administrative expense between Seller's and Summit's SLDA business,
and do not include any allocation for corporate marketing expenses.

     2.4 ABSENCE OF CERTAIN CHANGES AND EVENTS.  Since March 31, 1997, there has
not been:

         (a) Any material adverse change in the financial condition, results of
operation, assets, liabilities, business, or prospects of Seller or any
occurrence, circumstance, or combination thereof which reasonably could be
expected to result in any such material adverse change;

         (b) Any material transaction relating to or involving Seller (other
than the transactions contemplated herein) which was entered into or carried out
by Seller other than in the ordinary and usual course of business;

         (c) Any modification, waiver, change, amendment, release, rescission,
accord and satisfaction, or termination of, or with respect to, any term,
condition, or provision of any material contract, agreement, license, or other
instrument to which Seller or Summit is a party and relating to or affecting the
Assets, other than any satisfaction by performance in accordance with the terms
thereof in the usual and ordinary course of business and consistent with prior
practice;

         (d) Any notice (written or unwritten) from any employee of Seller that
such employee has terminated, or intends to terminate, such employee's
employment with Seller;

         (e) Any adverse relationships or conditions with vendors or customers
that may have a Material Adverse Effect; or

         (f) Any other event or condition of any character which has resulted in
a Material Adverse Effect, or may reasonably be expected to have a Material
Adverse Effect.

     2.5 CUSTOMERS AND COMMITMENTS.  Neither Summit nor Seller is aware nor has
any reason to believe that any of Seller's five largest customers during the
twelve month period ended March 31, 1997 (determined on the basis of both
revenues and bookings during such period) has terminated, or intends materially
to reduce or terminate, the amount of its business with Seller.  Schedule 2.5
contains a true, accurate and complete list of Seller's obligations and
commitments owed to customers or prospective customers and rights of customers
or prospective customers with respect to Seller's products.

     2.6 INVENTORY.  All inventory of Seller included in the Assets and, to the
knowledge of Seller, all items to be delivered to Seller for such inventory
after the Closing that are subject to purchase commitments outstanding at the
Closing, consist of items that are or upon delivery will be of a quality and
quantity presently usable and saleable in the ordinary course of business.

     2.7 TITLE TO ASSETS; ABSENCE OF LIENS AND ENCUMBRANCES.  Seller has good
and valid title to all of the Assets, free and clear of any Liens.  Seller has
full right and power to (and at the Closing will) sell, convey, assign, transfer
and deliver to Buyer good and valid title to all the Assets, free and clear of
any and all Liens, except (i) for the Assumed Liabilities, (ii) for statutory
liens for taxes not yet due (none of which shall be the obligation of CSC or
Buyer) and (iii) as set forth on Schedule 2.7. The Assets are in good operating
condition and repair, reasonable wear and tear excepted, and are suitable and
adequate for use in the ordinary course of business and conform in all material
respects to all applicable laws.  All leases are binding, valid and enforceable
on the Seller in accordance with their terms and, to the knowledge of the
Seller, are enforceable against the other party or parties thereto in accordance
with their terms, in each case subject to the effect, if any, of (i) applicable
bankruptcy and
<PAGE>
 
other similar laws affecting the rights of creditors generally, and (ii) rules
of law governing specific performance, injunctive relief and other equitable
remedies.  Seller is not in default under any lease and there has not occurred
any event which, with the giving of notice or lapse of time or both, would
constitute a material default under any lease.  To the knowledge of Seller,
there are no current defaults by any other party to any lease or events that
have occurred which, with the giving of notice or lapse of time or both, would
constitute a material default by such party under any lease.  After the Closing
Date, Buyer will be entitled to the continued use and possession of the personal
property leased by it, for the terms specified in such leases and for the
purposes consistent with the past practices of the Seller.

     2.8  COMPLIANCE WITH LAWS.  Seller has complied and is in compliance with
all applicable foreign, federal, state, and local laws, statutes, licensing
requirements, rules, and regulations, and judicial or administrative decisions
where the failure to comply could have a Material Adverse Effect.  There is no
order issued, investigation, or proceeding pending or notice served on Summit or
Seller or, to Seller's and Summit's knowledge, threatened, with respect to any
violation of any law, ordinance, order, writ, decree, rule, or regulation issued
by any federal, state, local, or foreign court or governmental agency or
instrumentality applicable to the Assets.

     2.9  CONSENTS.  The execution and delivery of this Agreement by the Seller
and Summit does not, and the performance of this Agreement and the Related
Agreements by the Seller and Summit do not, require any consent, approval,
authorization or permit of, or filing with or notification to, any governmental
or regulatory authority, domestic or foreign, or any other third party,
including licensors and lenders, except for applicable requirements, if any, of
bulk sales laws and the notification requirements of the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended (the "HSR Act").

     2.10 PROPRIETARY RIGHTS.

          (a) Seller (i) owns all right, title and interest in, (ii) is
exclusively licensed, or (iii) is otherwise entitled to exercise, without
restriction, all rights to all patents, trademarks, trade names, service marks,

and any applications or registrations therefor, and all inventions, mask work
layouts, net lists, source code, object code, schematics, technical drawings,
technology, know-how, processes, formulas, algorithms, computer software
programs, documentation, and all other tangible and intangible information or
material in any form which form part of the Assets, without any conflict with or
infringement of the rights of others and free and clear of any Liens
(collectively, the "Intellectual Property Rights").  Seller has the right to
use, sell, license, assign, transfer, convey or dispose of the Intellectual
Property Rights or the products, processes and materials covered thereby.

          (b) Schedule 2.10(b) sets forth: (i) all copyrights, patents, patent
applications, trademarks, service marks, tradenames, and other company, product
or service identifiers owned by or licensed to Seller with respect to the
Intellectual Property Rights; (ii) the jurisdictions) in which an application
for patent or application for registration, if any, of each Intellectual
Property Right has been made, including the respective application numbers and
dates; (iii) the jurisdiction(s), if any, in which each such Intellectual
Property Right has been patented or registered, including the respective patent
or registration numbers and dates; (iv) all licenses, sublicenses and other
agreements to which Seller is a party and pursuant to which any other party is
authorized to use, exercise, or receive any benefit from the Intellectual
Property Rights (other than to end-user licenses entered into in the.ordinary
course of business); and (v) all parties to whom the Seller has delivered copies
of its source code, whether pursuant to an escrow arrangement or otherwise, or
parties who have the right to receive such source code.  Seller has delivered to
CSC copies of all licenses, sublicenses, and other agreements identified
pursuant to
<PAGE>
 
clause (iv) above.  Seller and, to the knowledge of Seller, each other party
thereto, is in compliance with all material terms and conditions of all such
licenses, sublicenses, and other agreements.  Seller has no knowledge of any
claim, threatened claim or facts indicating that Seller or any other party
thereto has breached any material terms or conditions of such licenses,
sublicenses, or other agreements.

           (c) Seller has taken all necessary and appropriate steps, including,
without limitation, the filing of copyright, and trademark applications to
perfect and protect its interest in the Intellectual Property Rights in all
countries and other jurisdictions in which the Seller does business, except
where the failure to take such actions or make such applications or filings
would not (i) have a Material Adverse Effect or (ii) materially interfere with
the use or enforcement of the Intellectual Property Rights in the ordinary
course of business.  Seller has the exclusive right to file, prosecute, and
maintain such applications and the patents and registrations that issue
therefrom.

           (d) To Seller's knowledge, after due inquiry, all patents and
registered trademarks, service marks, and other company, product or service
identifiers and copyrights held by Seller are valid and enforceable.

           (e) Seller and Summit have secured valid written assignments from all
consultants and employees who contributed to the creation or development of the
Intellectual Property Rights of the rights to such contributions that the Seller
does not already own by operation of law except where failure to secure such
assignments would not have a Material Adverse Effect.

           (f) To Seller's knowledge, there has not been and there is not now
any unauthorized use, infringement or misappropriation of any of the
Intellectual Property Rights by any third party, including, without limitation,
any service provider of Summit or Seller.

           (g) Seller has not brought any actions or lawsuits alleging (i)
infringement of any of the Intellectual Property Rights or (ii) breach of any
license, sublicense or other agreement authorizing another party to use the
Intellectual Property Rights.  To Seller's knowledge, there do not exist any
facts which could form the basis of any such action or lawsuit.  Seller has not
entered into any agreement granting any third party the right to bring
infringement actions with respect to, or otherwise to enforce rights with
respect to, any of the Intellectual Property Rights.

           (h) No person has asserted or, to the knowledge of Seller, threatened
to assert any claims with respect to the Intellectual Property Rights (i)
contesting the right of Seller to use, exercise, sell, license, transfer or
dispose of any of the Intellectual Property Rights or any products, processes or
materials covered thereby or (ii) challenging the ownership, validity or
enforceability of any of the Intellectual Property Rights.  No Intellectual
Property Right is subject to any outstanding order, judgment, decree,
stipulation or agreement related to or restricting in any manner the licensing,
assignment, transfer or conveyance thereof by Seller.

           (i) Schedule 2.10(i) sets forth: (i) all copyrights, patents, patent
applications, trademarks, service marks, tradenames, trade secrets and other
company, product or service identifiers licensed to Seller ("In-licensed
Intellectual Property Rights") and (ii) all licenses, sublicenses and other
agreements to which Seller is a party and pursuant to which Seller is authorized
to use, exercise, or  receive any benefit from any In-Licensed Intellectual
Property Right (other than commercially available, I.E., "off-the-shelf"
software).  Seller has delivered to CSC copies of all licenses, sublicenses and
other agreements identified pursuant to clause (ii) above.  Seller and, to
Seller's knowledge, each other party thereto is in compliance with all material
terms and conditions of all such licenses, sublicenses, and other agreements.
Seller has no knowledge of any claim, threatened claim or the existence of any
facts
<PAGE>
 
indicating that Seller or any other party thereto has breached any material
terms or conditions of such licenses, sublicenses, or other agreements.

           (j) No In-Licensed Intellectual Property Right is subject to any
outstanding order, judgment, decree, stipulation or agreement related to, or
restricting in any manner, the use or licensing thereof by Seller.

           (k) Seller has the right to sell, assign, transfer, and convey all of
its right, title and interest in and to the Intellectual Property Rights and In-
Licensed Intellectual Property Rights to Buyer.  Seller is not, nor will be as a
result of the execution and delivery of this Agreement or the Related Agreements
or the consummation of the transactions contemplated hereby or thereby, in
violation of, breach of nor will Seller forfeit, terminate or in any way impair
any material Intellectual Property Right or In-Licensed Intellectual Property
Right whether or not pursuant to any license, sublicense or agreement with
respect to the Intellectual Property Rights or In-Licensed Intellectual Property
Rights set forth or required to be set forth in the Seller Schedules, or in any
way impair the right of Buyer to use, sell, license or dispose of or to bring
any action for the infringement of, any Intellectual Property Right or In-
Licensed Intellectual Property Right or any products or technology designed,
developed, manufactured, sold or serviced by Seller (collectively, "Products").

           (l) To Seller's knowledge, the manufacture, marketing, license, sale
or use of any Products anywhere in the world does not (i) violate any material
license or agreement with any third party, or (ii) infringe on any intellectual
property right of any third party. Neither Summit nor Seller knows of any claims
to the effect that the manufacture, marketing, license, sale or use of any
Product infringes any copyright, patent, trade secret, or other intellectual
property right of any third party or violates any license or agreement with any
third party. Neither Seller nor Summit has received service of process or been
charged in writing as a defendant in any claim, suit, action or proceeding that
alleges that any Asset infringes any patents, trademarks, service marks, trade
secret rights, copyrights or other intellectual property rights of any third
party, which has not been finally adjudicated prior to the date hereof. Neither
Seller nor Summit has any outstanding restrictions or infringement liability
with respect to any patent, trade secret, trademark, service mark, copyright or
other intellectual property right of another which relates to the Assets.

           (m) Seller and Summit have taken all necessary and appropriate steps
to protect and preserve the confidentiality of, and proprietary rights in, all
inventions, algorithms, formulas, schematics, technical drawings, ideas, know-
how, processes not otherwise protected by patents or patent applications, source
code, program listings, and trade secrets ("Confidential Information"),
including, without limitation, marking all such Confidential Information with
appropriate "Proprietary" or "Confidential" legends, establishing policies for
the handling, disclosure, and use of Confidential Information, and the
acquisition of valid written nondisclosure agreements from any party (including
Summit and Seller employees) receiving Confidential Information (the form of
which has been provided to CSC and its counsel), except where failure to take
such steps would not have a Material Adverse Effect. All Confidential
Information is presently, and as of the Closing will be, located at Seller's
address as set forth in this Agreement. No person other than Seller has used,
divulged or appropriated Confidential Information except for the benefit of
Seller. No person has used, divulged or appropriated Confidential Information to
the detriment of Seller other than pursuant to the terms of written agreements
between Seller and such other persons.

     2.11  RESTRICTIVE DOCUMENTS OR ORDERS.  Neither Summit nor Seller is a
party to or bound by any agreement, contract, order, judgment, or decree, or any
similar restriction not of general application which (i) has, or could
reasonably be expected to have, a Material Adverse Effect, or (ii)
<PAGE>
 
materially adversely affects, or could reasonably be expected to materially
adversely affect, the consummation of the transactions contemplated by this
Agreement or the Related Agreements.

     2.12  CONTRACTS AND COMMITMENTS.

           (a)  Schedule 2.12 sets forth a list of all outstanding licenses,
contracts or other agreements, whether or not in writing, to which obligations
are owing by  the Seller and which are related to the Assets or pursuant to
which Seller or Summit derives any benefits relating to the Assets (collectively
"Contracts").

           (b) Seller has performed all of its obligations under the terms of
each Contract, and is not in default thereunder, in either case, except where
such non-performance or default would have a Material Adverse Effect. No event
or omission has occurred which but for the giving of notice or lapse of time or
both would constitute a default by Seller or, to Seller's knowledge, any other
party thereto under any such Contract where such default by any such party could
have a Material Adverse Effect. Each Contract is valid and binding on the Seller
and, to the knowledge of the Seller, on each other party thereto and is in full
force and effect. Neither Summit nor Seller has received any notice of default,
cancellation, or termination in connection with any Contract.

     2.13  ASSETS.  Upon or after the Closing, Buyer will have all the
intellectual property that Seller or Summit owned or had the right to use that
was necessary to operate the business of Seller relating to Seller's TDS product
line (but not Seller's Visual Test Bench product line) prior to the Closing.
The Assets are suitable for the purpose or purposes for which they are being
used by Seller prior to the Closing, and are free from any known defects, except
such minor defects as do not interfere with the continued use thereof.

     2.14  INSURANCE.  Schedule 2.14 sets forth all insurance policies and
fidelity bonds covering the Assets.  All such insurance policies and fidelity
bonds will terminate as of the Closing.  There is no claim by the Seller pending
under any of such policies or bonds as to which coverage has been questioned,
denied or disputed by the underwriters of such policies or bonds.

     2.15  PRODUCT WARRANTIES AND ITS PRODUCT LIABILITY.  Seller is not
obligated under any product warranty relating to the Assets, except pursuant to
Seller's standard product license agreement (a form of which is attached hereto
as Schedule 2.15). Seller is not aware of any claim in excess of claims made in
the ordinary course of business.

     2.16  LITIGATION.  Except as disclosed in documents that Summit has filed
with the Securities and Exchange Commission before the date of this Agreement,
there is no claim, investigation, litigation, action, suit, or administrative or
judicial proceeding pending or threatened against Summit or Seller, or to
Seller's or Summit's knowledge, any officer or director of Summit or Seller, and
involving the Assets.  Neither Summit nor Seller has received any complaints
from any of its customers or suppliers within the last year, which complaints
could reasonably be expected individually or in the aggregate, to have a
Material Adverse Effect.

     2.17  INTERESTED PARTY RELATIONSHIPS.  Neither Summit nor Seller, nor any
officer or director of Summit or Seller has any material financial interest,
direct or indirect, in any material supplier or customer or any party to any
contract that is included in the Assets.

     2.18  BOOKS AND RECORDS.  The books and records of Summit and Seller to
which CSC, Buyer and their accountants and attorneys have been given access are
the true books and records of
<PAGE>
 
Summit and Seller and accurately reflect, when read together, the underlying
information presented therein in all material respects.

     2.19  COMPLETE DISCLOSURE.  To the knowledge of Summit's Chief Executive
Officer and Chief Financial Officer, no representations or warranties made by
Summit or Seller in this Agreement, nor any document, written information,
written statement, financial statement, certificate or exhibit prepared and
furnished or to be prepared and furnished by Summit or Seller or its
representatives to CSC or Buyer pursuant hereto or the Related Agreements or
otherwise in connection with the transactions contemplated hereby or thereby,
when read together, contains or will contain any untrue statement of a material
fact, or omits or will have failed to state a material fact necessary to make
the statements or facts contained herein or therein not misleading; PROVIDED,
HOWEVER, that the above mentioned information contains projections and other
forward looking statements.  There is no presently existing event, fact or
condition that would have, has or could reasonably be expected to have a
Material Adverse Effect, which has not been set forth in this Agreement or the
Related Agreements or the exhibits hereto or thereto or otherwise disclosed by
Summit or the Seller to CSC or Buyer in writing prior to or on the Closing Date.
Seller and/or Summit, as the case may be, has prepared such disclosure documents
in good faith.

     2.20  BACKLOG.  Schedule 2.21 sets forth the backlog of orders that the
Seller is to ship and contract work to be performed as of May 1, 1997, and such
schedule will be updated to indicate such backlog as of the Closing.  The Seller
either (i) possesses sufficient inventory of Products, materials and personnel
to produce the same within their schedule delivery dates or (ii) such Products
or materials have lead times such that the Seller can acquire or produce such
Products and materials in time to produce and ship such backlog in accordance
with its scheduled shipping date.

     7.4 NOTICE AND OPPORTUNITY TO DEFEND AGAINST THIRD PARTY CLAIMS.

         (a) Promptly after receipt from any third party by any party hereto of
a written notice of any demand, claim or circumstance that, immediately or with
the lapse of time, would give rise to a claim or the commencement (or threatened
commencement) of any action, proceeding or investigation (an "Asserted
Liability") that may result in Losses for which indemnification may be sought
hereunder, the party seeking indemnification pursuant to Section 7.2 or 7.3 (the
"Indemnitee") shall give written notice thereof (the "Claims Notice") to the
party obligated to provide indemnification pursuant to Section 7.2 or 7.3 (the
"Indemnifying Party"), PROVIDED, HOWEVER, that a failure to give such notice
shall not prejudice the Indemnitee's right to indemnification hereunder except
to the extent that the Indemnifying Party is actually and materially prejudiced
thereby.  The Claims Notice shall describe the Asserted Liability in reasonable
detail, and shall indicate the amount (estimated, if necessary) of the Losses
that have been or may be suffered by the Indemnitee when such information is
available.

         (b) The Indemnifying Party may elect to compromise or defend, at its
own expense and by its own counsel, any Asserted Liability.  If the Indemnifying
Party elects to compromise or defend such Asserted Liability, it shall, within
20 business days following its receipt of the Claims Notice (or sooner, if the
nature of the Asserted Liability so requires) notify the Indemnitee of its
intent to do so, and the Indemnitee shall cooperate, at the expense of the
Indemnifying Party, in the compromise of, or defense against, such Asserted
Liability.  If the Indemnifying Party elects not to compromise or defend the
Asserted Liability, fails to notify the Indemnitee of its election as herein
provided or contests its obligation to provide indemnification under this
Agreement, the Indemnitee may pay, compromise or defend such Asserted Liability
with all reasonable costs and expenses borne by the Indemnifying Party.
Notwithstanding the foregoing, neither the Indemnifying Party nor the Indemnitee
may settle or compromise any claim without the consent of the other party,
PROVIDED, HOWEVER, that such consent to settlement or compromise shall not be
unreasonably withheld.  In any event, the Indemnitee and the Indemnifying Party
may participate, at their own expense, in the defense of such Asserted
Liability; PROVIDED, HOWEVER, that if the Indemnitee reasonably determines that
there is a conflict of interest between the Indemnified Party and the
Indemnitee, the fees of such counsel shall be borne by the Indemnifying Party.
If the Indemnifying Party chooses to defend any claim, the Indemnitee shall make
available to the Indemnifying Party any books, records or other documents within
its control that are necessary or appropriate for such defense.

     7.5 PROCEDURE FOR INDEMNIFICATION WITH RESPECT TO NON-THIRD PARTY CLAIMS.
In the event that CSC and Buyer, on the one hand, and Summit and Seller, on the
other hand, assert the existence of a claim giving rise to Losses (but excluding
claims resulting from the assertion of liability by third parties), Indemnitee
shall give write notice to the Indemnifying Party.  Such written notice shall
state that it is being given pursuant to this Section 7.5, specify the nature
and amount of the claim asserted and indicate the date on which such assertion
shall be deemed accepted and the amount of the claim deemed a valid claim (such
date to be established in accordance with the next sentence).  If Indemnifying
Party, within sixty (60) days after the mailing of notice by Indemnitee, shall
not give written notice to Indemnitee announcing its intent to contest such
assertion of Indemnitee, such assertion shall be deemed accepted and the amount
of claim shall be deemed a valid claim.  In the event, however, that
Indemnifying Party contests the assertion of a claim by giving such written
notice to Indemnitee within said period, then the parties shall act in good
faith to reach agreement regarding such claim.  In the event that litigation
shall arise with respect to any such claim, the prevailing party shall be
entitled to reimbursement of costs and expenses incurred in connection with such
litigation, including attorney's fees, if the parties hereto, acting in good
faith, cannot reach agreement with respect to such claim within ten (10) days
after such notice.
<PAGE>
 
     7.6 NET INDEMNITY.  The amount of any Losses from and against which either
party is liable to indemnify, reimburse, defend and hold harmless the other
party or any other person pursuant to Section 7.2 or Section 7.3 shall be
reduced by any insurance or other recoveries or any tax benefit that such
indemnified person realizes or may realize as a result of or in connection with
such Loss and increased by any taxes such indemnified person realizes or may
realize in respect of indemnification for such Loss.

     7.7 LIMITS ON INDEMNIFICATION.  Absent fraud or willful misconduct of any
party (for which there shall be no limitation of liability of any party), no
party shall have any right to seek indemnification under this Agreement (i)
until Losses which would otherwise be indemnifiable hereunder and have been
incurred by such party and other indemnitees associated with or related to such
party exceed $100,000 after insurance or other recoveries and on an after-tax
basis in the aggregate (provided that after such $100,000 amount has been
satisfied, the Indemnitee shall be entitled to recover all Losses, including
such $100,000 amount); or (ii) for an aggregate amount in excess of $5,000,000.
The parties to this Agreement shall have liabilities and obligations for Losses
under this Article VII only with respect to claims submitted or notice of claims
provided during the relevant time period of survivability of the specific
representation, warranty, covenant or agreement as set forth herein.
Notwithstanding the expiration dates of the representations, warranties,
covenants and agreements set forth herein, if any party to this Agreement shall
provide notice to the other parties with respect to the submission of a claim
during the time period of survivability of such representation, warranty,
covenant or agreement, such Indemnifying Party's (as defined herein) liability
or obligation for Losses identified in such notice shall continue in full force
and effect until a final determination of such liability or obligation with
respect to those claims timely made.


                                  ARTICLE VIII

                       TERMINATION, AMENDMENT AND WAIVER

     8.1 TERMINATION.  Except as provided in Section 8.2 below, this Agreement
may be terminated and the Acquisition abandoned at any time prior to the Closing
Date:

         (a) by mutual consent of Seller and Buyer;

         (b) by CSC or Summit if: (i) there shall be a final nonappealable order
of a federal or state court in effect preventing consummation of the
Acquisition; or (ii) there shall be any statute, rule, regulation or order
enacted, promulgated or issued or deemed applicable to the Acquisition by any
Governmental Entity that would make consummation of the Acquisition illegal;

         (c) by CSC if there shall be any action taken, or any statute, rule,
regulation or order enacted, promulgated or issued or deemed applicable to the
Acquisition by any Governmental Entity, which: (i) results in the issuance of
such an order or injunction, or the imposition against any party hereto of
substantial damages if the Acquisition is consummated, (ii) prohibits CSC's or
Buyer's ownership or operation of all or a material portion of the Assets or
compels the Buyer or Seller to dispose of or hold separate all or a material
portion of the Assets of Buyer or Seller as a result of the sale of the Assets,
(iii) materially limits or restricts Buyer's conduct or operation of the Assets
after the Closing, or (iv) renders any party hereto unable to consummate the
sale of the Assets.  In the event any such order or injunction shall have been
issued, each party agrees to use its reasonable efforts to have any such
injunction lifted;
<PAGE>
 
         (d) by CSC if it is not in material breach of its obligations under
this Agreement or the Related Agreements and there has been a material breach of
any representation, warranty, covenant or agreement contained in this Agreement
or the Related Agreements on the part of Summit or Seller and such breach has
not been cured within ten (10) business days after written notice to Summit and
Seller (provided that, no cure period shall be required for a breach which by
its nature cannot be cured);

         (e) by Summit if it is not in material breach of its obligations under
this Agreement and there has been a material breach of any representation,
warranty, covenant or agreement contained in this Agreement or the Related
Agreements on the part of CSC or Buyer and such breach has not been cured within
ten (10) business days after written notice to CSC and Buyer (provided that, no
cure period shall be required for a breach which by its nature cannot be cured).

     8.2 EFFECT OF TERMINATION.  In the event of termination of this Agreement
as provided in Section 8.1, this Agreement shall forthwith become void and there
shall be no liability or obligation on the part of any party hereto, or their
respective officers, directors, securityholders or Affiliates, provided that
each party shall remain liable for any breaches of this Agreement prior to its
termination; and provided further that, the provisions of Sections 4.3, 5.2,
5.3, 5.4, 5.12 and 9.7 of this Agreement shall remain in full force and effect
and survive any termination of this Agreement.

     8.3 AMENDMENT.  This Agreement may be amended by the parties hereto at any
time by execution of an instrument in writing signed on behalf of each of the
parties hereto.

     8.4 EXTENSION; WAIVER.  At any time prior to the Closing Date, CSC, on the
one hand, and Summit, on the other, may, to the extent legally allowed, (i)
extend the time for the performance of any of the obligations of the other party
hereto, (ii) waive any inaccuracies in the representations and warranties made
to such party contained herein or in any document delivered pursuant hereto, and
(iii) waive compliance with any of the agreements or conditions for the benefit
of such party or Seller or Buyer, as applicable, contained herein.  Any
agreement on the part of a party hereto to any such extension or waiver shall be
valid only if set forth in an instrument in writing signed on behalf of such
party and shall not be deemed to be a waiver or extension of any other condition
or breach of any other representation or warranty nor shall the forbearance by
any party to seek a remedy for any noncompliance or breach by any other party
hereto be deemed to be a waiver by such party of any rights or remedies with
respect to such breach or noncompliance.

Agreement unless otherwise indicated.  The words "include," "includes" and

                                CONFIDENTIALITY

     5.1  OBLIGATIONS.  Each party (the "receiving party") acknowledges and
agrees that any business and technical information provided to the receiving
party by the other party (the "disclosing party") hereunder constitutes the
confidential and proprietary information of the disclosing party, and that the
receiving party's protection thereof is essential to this Agreement and a
condition to the receiving party's use and possession thereof.  The receiving
party shall retain in strict confidence and not disclose to any third party
(except as authorized by this Agreement) without the disclosing party's express
written consent, any and all such information.  CSC acknowledges and agrees that
the VTB Software is confidential and proprietary information of SDI.

     5.2  EXCEPTIONS.  The receiving party shall be relieved of this obligation
of confidentiality to the extent any such information:

          (i)   was in the public domain at the time it was disclosed or has
     become in the public domain through no fault of the receiving party;

          (ii)  the receiving party can prove was known to the receiving party,
     without restriction, at the time of disclosure as shown by the files of the
     receiving party in existence at the time of disclosure;

          (iii) is disclosed by the receiving party with the prior written
     approval of the disclosing party;

          (iv)  the receiving party can prove was independently developed by the
     receiving party without any use of the disclosing party's confidential
     information and by employees or other agents of the receiving party who
     have not had access to any of the disclosing party's confidential
     information; or

          (v)   becomes known to the receiving party, without restriction,
     from a source other than the disclosing party without breach of this
     Agreement by the receiving party and otherwise not in violation of the
     disclosing party's rights.

     5.3  SOURCE CODE PROTECTIONS.  Unless as otherwise permitted under this
Agreement or another written agreement between CSC and SDI, CSC shall not under
any circumstances attempt, or knowingly permit others to attempt, to decompile,
decipher, disassemble, reverse engineer or otherwise determine the source code

     5.4  CONFIDENTIALITY AGREEMENTS.  The receiving party, prior to permitting
access by any individual to any of the disclosing party's confidential
information, shall enter into a confidentiality agreement with each such
individual which (i) incorporates the protections and restrictions set forth
herein for the disclosing party's confidential information; (ii) provides that
the individual's obligations with respect to the disclosing party's confidential
information shall continue after termination of the individual's employment,
consulting relationship or other relationship with the receiving party; and
(iii) provides that the disclosing party is a direct and intended beneficiary of
the agreement and entitled to enforce it directly against the individual.

     5.5  NOTIFICATION OF SECURITY BREACH.  The receiving party agrees to notify

threaten irreparable harm to the disclosing party, and, accordingly, the
receiving party agrees that in the event of such breach the disclosing party
shall be entitled to seek equitable relief to protect its interest therein,
including but not limited to preliminary and permanent injunctive relief, as

     6.1  WARRANTY OF TITLE.  SDI warrants and represents to CSC that (i) CSC
shall acquire good and clear title to the VTB Software, free and clear of all
liens and encumbrances, (ii) all materials and services provided hereunder
including, without limitation, the VTB Software, are either owned or properly
licensed by SDI or are in the public domain and the use thereof by CSC, its

                                   Section 7
                                INDEMNIFICATION

     7.1  INDEMNIFICATION BY SDI.  SDI agrees to indemnify, defend and hold
harmless CSC, its affiliates, and their respective officers, directors,
employees, distributors, agents, successors and assigns from and against any and
all loss, damage, settlement or expense (including reasonable legal expenses),
as incurred, resulting from or arising out of any claims which allege that the
VTB Software or the use or sale thereof infringe upon, misappropriate or violate
any patents, copyrights, or trade secret rights or other proprietary rights of
persons, firms or entities who are not parties to this Agreement; provided that
CSC (i) promptly notifies SDI, in writing, of any notice or claim of such
alleged infringement or misappropriation involving the VTB Software of which it
becomes aware; (ii) permits SDI to control, the defense, settlement, adjustment
or compromise of any such claim; (iii) the claim does not result from
modification of the VTB Software which modification is not authorized by SDI;
and (iv) the claim does not result from the combination of the VTB Software with
software or equipment not provided by SDI if the VTB Software alone would not be
the subject of the claim.  CSC may employ counsel, at its own expense (provided
that if such counsel is necessary because SDI does not assume control, SDI will
bear such expense), to assist it with respect to any such claim.  CSC shall have
no authority to settle any claim on behalf of SDI.

     7.2  INJUNCTION.  If by reason of such infringement claim, CSC or its
customers shall be prevented or are likely to be prevented by legal means from
selling or using any VTB Software, or if, in SDI's opinion, such claim is likely
to occur, SDI will use its commercially reasonable efforts, at its
<PAGE>
 
expense, to: (i) obtain all rights required to permit the sale or use of the VTB
Software by CSC; or (ii) modify or replace such VTB Software to make then non-
infringing (and extend this indemnity thereof), provided that any such
replacement or modified VTB is functionally equivalent to the VTB Software.  If
SDI is unable to achieve either of the options set forth above within a
reasonable period of time after the issuance of the injunction, or reasonably
believes that an injunction will issue and that such options cannot be achieved
within a reasonable period of time, then neither party will sell or distribute
the VTB Software in accordance with the terms of such injunction-or SDI's
reasonable instructions.  Notwithstanding the foregoing, all payments due from
CSC hereunder shall be paid whether or not the VTB Software may be used, sold or
distributed by any of the parties under such injunction or instructions of SDI.
This Section 7 states SDI's entire obligation with respect to claims that the
VTB Software or any rights therein infringe or misappropriate the rights of any
third party.

purchased VTB Software from SDI.  Upon CSC's approval, subject to SDI executing
CSC's standard Sales Representative Agreement, SDI may solicit orders from its
VTB Software customers for CSC Wavebridge products, in which case CSC shall pay
to SDI a commission of forty percent (40%) of the amount received from CSC under
such sale.


                                   Section 9
                            LIMITATION OF LIABILITY

CONFIDENTIALITY OBLIGATIONS IN SECTION 5, IN NO EVENT SHALL EITHER PARTY'S
LIABILITY ARISING OUT OF THIS AGREEMENT OR THE TERMINATION OF THIS AGREEMENT
EXCEED THE AMOUNTS PAID BY CSC TO SDI PURSUANT TO THIS AGREEMENT.  IN NO EVENT
SHALL EITHER PARTY HAVE ANY LIABILITY FOR ANY INDIRECT, INCIDENTAL, SPECIAL OR
CONSEQUENTIAL DAMAGES, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, ARISING
OUT OF THIS AGREEMENT, INCLUDING BUT NOT LIMITED TO LOSS OF ANTICIPATED PROFITS,

                                  VTB SOFTWARE

VISUAL TESTBENCH COMPONENTS

Visual Testbench consists of modified Visual HDL for Verilog and VHDL, Visual IF
Testbench harness code, Visual HDL simulation interface, various internal TDS
routines, WDB input/output routines and Visual Testbench on-line documentation.
For customer delivery these source code modules are compiled to a single Visual
Testbench binary executable module.

A Testbench is created using the Visual HDL Flow chart editor, Block diagram
editor and Waveform/Timing diagram editor.  The Testbench is connected to the
simulated circuit using the Visual HDL Block Diagram editor and the Visual
Testbench Launch editor.

The Testbench harness is compiled with the customer's simulator and design as to
stimulate and examine the circuit under investigation.  The Testbench harness
reads and writes TSSI WDB databases through binary linkable library functions.

The examples include Visual HDL databases and Verilog or VHDL codes sufficient
to demonstrate basic and advanced product operation.  The examples are
operational and will produce legitimate WDB output.

DOCUMENTATION

Visual Testbench documentation consists of a binary file in Framemaker mif
format describing theory of operation, external controls, and function call
interface of the product.  The mif file is interpreted by a view for run time
viewing of the test.

          5.2.1  RESTRICTION ON TRANSFER.  Except as expressly provided in this
Agreement neither party shall sell, transfer, pledge nor otherwise dispose of

          In addition to the foregoing, neither party shall sell, transfer,

          5.2.2  TRANSFER TO EMPLOYEES OR OFFICERS. Notwithstanding any other
provisions hereof, either party may sell or transfer up to ten percent (10%) of
its shares in JVC to the party's employees and officers.  In this case, the

employees or officers leaves the employment of such transferring party, the
transferring party shall buy back all the shares in JVC possessed by such
employees or officers.

          5.2.3  FIRST REFUSAL RIGHT.  Except as provided in Section 5.2.2

either party (the "Selling Party") shall desire to sell, assign, or transfer any
or all of its shares, it shall give the other party written notice of such
desire, setting forth in such notice all of the details of such contemplated
sale, assignment or transfer, including without limitation thereto, the price,
currency, terms and conditions of such proposed transaction and the identity and
address of the proposed purchaser or transferee. The consideration in the case
of any such contemplated transaction may not be unique, or not readily
procurable, or a service to be performed for the Selling Party. The other party
shall have sixty (60) days after receipt of such notice to exercise its right of
first refusal option to purchase such shares at the same price, in the same
currency, and upon the same terms and conditions that the Selling Party has been
offered and is willing to accept from the proposed purchaser or transferee, by
mailing to the Selling Party a written notice thereof. If the other party so
exercises its right of first refusal option to purchase, it shall have an
additional four (4) months after such exercise within which to make payment for,
and take title to, the stock of the Selling Party. If the other party does not
so exercise its right of first refusal option, the Selling Party may sell,
assign or transfer such shares to the proposed

                                       5
<PAGE>
 
purchaser or transferee pursuant to the terms and conditions set forth in such
notice to the other party.

nominated by the party who nominated the director whose death, resignation, or

defend, indemnify  and hold harmless Licensee against and from any claims that

                             PARTY RESPONSIBILITIES

       3.1.1 ICC shall make every reasonable effort to manufacture quantities

based on a monthly forecast given to ICC by Innotech.

       3.1.2 ICC shall make every reasonable effort to satisfy Innotech's

       3.2.2 Innotech shall refrain from manufacturing or selling products
which are thought by both ICC and Innotech to directly compete with the JVC
Products for the duration of this Agreement, provided, however, it is not
prohibited that Innotech may provide its customer with delivery, service and
maintenance for directly competitive products if the equipment was supplied to
such customer prior to the start of this Agreement and Innotech is requested
to provide the above services by its customer. This prohibition against
selling competitive products shall not apply, however, to products

hereunder in accordance with price schedules or bulletins supplied by ICC and
accepted by Innotech from time to time.  The presently applicable schedule is
attached hereto as Appendix B.

  4.2  PRICE CHANGES.  ICC shall give Innotech at least ninety (90) days written
notice prior to any price change which may be made by ICC; provided that, in
case of price increase, notwithstanding the provision provided above, any order

purchase orders which shall be available to ICC for review upon reasonable
request.

  5.3  TAXES.  All taxes shall be set forth separately on the face of the order
acknowledgment.  Failure of ICC to so set forth any of these items shall relieve
Innotech from the obligation to pay such amounts.  In lieu of the imposition of
any particular tax, Innotech may, where applicable, provide a tax exemption
certificate to ICC in a form acceptable to the taxing authorities.


                                   ARTICLE 6.

  The terms of payment and applicable discounts shall be as provided in Appendix
A attached hereto.  In case a  JVC Product does not meet specifications which
have been committed by mutual agreement and Innotech does not obtain customer
acceptance due to an engineering problem of the machine, payment to ICC shall be
adjusted accordingly.  If payment has been made by Innotech to ICC on that JVC
Product, the next payment shall be adjusted accordingly.


                                   ARTICLE 7.
                                    DELIVERY
                                        
  7.1  GENERAL.  ICC shall make every reasonable effort to fill all orders
promptly upon acceptance thereof.  However, if conditions beyond the control of
ICC arise which prevent compliance with normal delivery schedules, ICC shall not
be liable for damages, general, special or otherwise arising from such delivery
delay.

       All sales are made F.O.B. point of shipment, ICC facility in Machida-shi,

discretion with respect to manner of shipment and insurance to be used.

  7.2  RISK OF LOSS.  ICC shall retain title and bear the risk of loss until
such time as a shipment has been placed on board the carrier at the factory, at
which time title shall pass to Innotech and the risk of loss shall be borne by
Innotech.

is generally known to the public, or (ii) which subsequently becomes generally
known to the public through no fault of the receiving party, or (iii) which has,
at the time of disclosure thereof, been in the possession of the receiving
party, or (iv) which may subsequently be rightfully obtained by the receiving
party from a third party without confidential restriction, or (v) which may
subsequently be developed by the receiving party independently of the
CONFIDENTIAL INFORMATION.

liability law in the Territory, which result from such Innotech's alteration,
modification or change in any Product or the use of any non-ICC part.

                                  ADVERTISING

  ICC shall supply reasonable quantities of materials such as catalogs,
brochures of new JVC Products, and reprints of its advertising materials at no
charge to Credence.  Credence shall have the right to conduct advertising
campaigns with respect to the JVC Products but shall be required to obtain an
approval of ICC prior to releasing the same.  Credence agrees to refrain from
making any claims or representations concerning the JVC Products in excess of
those made by ICC.

  ICC and Credence may jointly conduct advertising and/or sales promotion in the
Territory with respect to the JVC Products upon mutual agreement.

                                  WARRANTIES

  Products are warranted in accordance with ICC's standard Hardware and Software
Warranties set forth in Appendix F. The warranty period determined in Appendix F
begins upon completion of installation procedures, including customers'
acceptance, at the customer site.  The warranty services for the JVC Products
during the warranty period shall be provided by Credence to Credence's
customers.

                               PRODUCT LIABILITY
                                        
  If, under the product liability law in the Territory, any claim is made or any
suit or action is instituted against Credence and/or Credence's customers
arising out of or otherwise in connection with any defect or alleged defects of
the JVC Products supplied by ICC to Credence under this Agreement, ICC shall, at
its own expenses and upon request of Credence:

  (i)  investigate or research the causes of accidents, occurrences, injuries or
losses affecting any person or property as a result of the manner in which the
JVC Products are designed, manufactured, treated, fabricated, constructed,
packaged, labeled, delivered, sold or used, and use its every reasonable effort
to correct or eliminate such causes within a reasonable period; and

                                      6
<PAGE>
 
  (ii)  support Credence's recall, repair, replacement in whole or in part or
research into the need to recall any JVC Products supplied by ICC to Credence in
the event that such recall is required by law or is considered necessary or
prudent by mutual agreement of Credence and ICC, and indemnify and hold harmless
Credence from and against all costs and expenses of any kind whatsoever arising
out of or in connection with such recall, repair, replacement and/or research;
and

  (iii) provide to Credence any and all assistance (including, without
limitation, technical and other information, documents, data, materials and
witnesses) which are, in the opinion of Credence or its counsel, necessary or
useful for Credence's defense to such claim, suit or action in relation to the
JVC Products supplied by ICC to Credence hereunder.

  (iv)  If a succession of claims are made, or a succession of suits or actions
are instituted (whether or not they are against Credence, and whether or not
they are made or instituted in the Territory) in relation to a product
manufactured by ICC which is the same as or similar to the JVC Products supplied
by ICC to Credence hereunder, then notwithstanding anything else in this
Agreement; (1) ICC shall, at the request of Credence, stop delivery of the JVC
Products to Credence; and (2) Credence shall have no obligation to purchase or
take delivery of the JVC Products, until ICC can establish to Credence's
complete satisfaction that: (a) the JVC Products arc free from defects in
materials, design, workmanship, manufacture, treatment, fabrication,
construction, packaging, instruction manuals, labeling, warnings or otherwise;
or (b) all such defects have been completely corrected or eliminated.

  (v)   If ICC is unable to satisfy Credence in such manner as stipulated in
subsection (iv) above within a ninety (90) days period, Credence may terminate
this Agreement by written notice with immediate effect.  Upon termination,
Credence shall have no obligation to purchase or accept delivery of any JVC
Products remaining undelivered under this Agreement, and ICC shall, upon
Credence's request, buy back from Credence any and all JVC Products and parts
thereof then in Credence's inventory.  The re-purchase price for such JVC
Products shall include the original purchase price in Japanese Yen paid by
Credence to ICC, plus freight costs, import duty and customs clearance charges
paid on such JVC Products.

                                  TERMINATION
                                        
  14.1  GENERAL.

       14.1.1 This Agreement may be terminated (i) by an agreement in writing
duly signed by the parties hereto, or (ii) by either party at will, with or
without cause, upon not less than ninety (90) days written notice, given by
registered or certified mail to the other party; provided, however, that
neither party hereto shall, by reason of the termination of this Agreement
pursuant to this Article 14.1.1, be liable to the other for compensation,
reimbursement or damages on account of the loss of prospective profits on
anticipated sales, or on account of expenditures, investments, leases or
commitments in connection with the business or good will of ICC or Credence,
or otherwise.

       14.1.2 Either party hereto may terminate this Agreement by giving a
written notice of termination to the other party upon occurrence of any of the
following events; provided, however, that the termination of this Agreement
pursuant to this Article 14.1.2 doesn't prevent claims for damages from the
unliable party for such termination:

       (i)   When the other party becomes or is caused to become insolvent or
any voluntary or involuntary petition in bankruptcy or for corporate
reorganization is filed by or against the other party, or a receiver is
appointed with respect to any of the assets of the other party, or liquidation
proceeding is commenced by or against the other party, and such proceeding is
not discharged within sixty (60) days;

       (ii)  When the whole or any substantial part of the business or assets
of the other party is transferred to a third party by agreement, order of
court or otherwise; or

       (iii) When the other party defaults in payment for the JVC Products or
otherwise defaults in any of the provisions of this Agreement and does not make
the payment or remedy the default within thirty (30) days after a written notice
is given requesting to make the payment or remedy the default.

  14.2  SALES AFTER TERMINATION.  The acceptance of any order from or the sale
of any JVC Products to Credence after the termination of this Agreement shall
not be construed as a renewal or extension hereof nor as a waiver of
termination.

  14.3  TRADE NAMES.  If during the term of this Agreement, Credence uses signs
containing the name of ICC or uses any trade name, trademark, or the listing of
ICC's name in any telephone book, directory, public record or elsewhere,
Credence, regardless of the cause of termination of this Agreement, will take
all reasonable and necessary steps to discontinue any use

                                      8
<PAGE>
 
of the aforementioned in any manner whatsoever and cause the removal of ICC's
name from any such listing.

  14.4  INVENTORY BUY-BACK.  In the event ICC terminates this Agreement for its
convenience, rather than as a result of Credence's default or insolvency, or
Credence terminates this Agreement as a result of ICC's default or insolvency,
ICC shall buy back from Credence any and all JVC Products and part thereof
purchased by Credence then in Credence's inventory.

  The re-purchase price for such JVC Products shall include the original
purchase price in Japanese Yen paid by Credence to ICC, plus freight costs,
import duty and customs clearance charges paid on such JVC Products.

  In the event that ICC terminates this Agreement as a result of Credence's
insolvency, or its default of obligations hereunder or if Credence terminates
this Agreement for any reason excluding as a result of ICC's defaults or
insolvency, ICC shall have first right of purchase, but no obligation to
repurchase any of its JVC Products from Credence.

  14.5  EFFECT OF TERMINATION.  Article 3.1.4, Article 8, Article 9.4, Article
11, Article 12, Article 14, Article 15, Article 16 and Article 17 shall survive
and continue to be effective after the termination of this Agreement.

  All disputes, controversies, or differences which may arise between the
parties, out of or in relation to or in connection with this Agreement or the
breach hereof, which cannot be satisfactorily resolved by the parties
themselves, shall be finally settled by arbitration pursuant to the Japan -
American Trade Arbitration Agreement of September 16, 1952, by which each party
hereto is bound.  The arbitration shall be held in Tokyo, Japan or any other
convenient location mutually agreed upon by the parties.
