                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                  (Unaudited)

1.   THE COMPANY

LTX Corporation ("LTX" or the "Company") designs, manufactures, and markets
automatic test equipment for the semiconductor industry that is used to test
system-on-a-chip, digital, analog, and mixed signal (a combination of digital
and analog) integrated circuits ("ICs"). The Company's newly introduced Fusion
product is a single test platform that can be configured to test system-on-a-
chip devices, digital VLSI devices including microprocessors and
microcontrollers, and analog/mixed signal devices. The Company also sells
hardware and software support and maintenance services for its test systems. The
semiconductors tested by the Company's systems are widely used in the computer,
communications, automotive and consumer electronics industries. The Company
markets its products worldwide to manufacturers of system-on-a-chip, digital,
analog and mixed signal ICs. The Company is headquartered, and has development
and manufacturing facilities, in Westwood, Massachusetts, a development facility
in San Jose, California, and worldwide sales and service facilities to support
its customer base.

Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements have been prepared by the Company, without
audit, and reflect all adjustments, which, in the opinion of management, are
necessary for a fair statement of the results of the interim periods presented.
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amount of assets and liabilities and disclosures of
contingent assets and liabilities as of the date of the financial statements and
the reported amounts of income and expenses during the reporting periods.

Certain information and footnote disclosures normally included in the annual
financial statements, which are prepared in accordance with generally accepted
accounting principles have been condensed or omitted.  Accordingly, although the
Company believes that the disclosures are adequate to make the information
presented not misleading, the financial statements should be read in conjunction
with the footnotes contained in the Company's Annual Report on 10-K.

Foreign Currency Translation

The financial statements of the Company's foreign subsidiaries are translated in
accordance with Statement of Financial Accounting Standards No. 52, "Foreign
Currency Translation". The Company's functional currency is the U.S. dollar.
Accordingly, the Company's foreign subsidiaries translate monetary assets and
liabilities at year-end exchange rates while non-monetary items are translated
at historical rates. Income and expense accounts are translated at the average
rates in effect during the year, except for sales, cost of sales and
depreciation, which are primarily translated at historical rates. Net realized
and unrealized gains and losses resulting from foreign currency remeasurement
and transaction gains and losses were a gain of $267,000  and a loss of $460,000
for the three months ended October 31, 1999 and 1998 respectively.  The

                                       4
<PAGE>

amounts for both periods were principally due to fluctuations in the Japanese
yen. Transaction gains and losses are included in the consolidated results of
operations.

Revenue Recognition

Revenues from product sales and related warranty costs are recognized at the
time of shipment. Service revenues are recognized over the applicable
contractual periods or as services are performed.  Revenues from engineering
contracts are recognized over the contract period on a percentage of completion
basis.

During April 1998, Ando Electric Co., Ltd. ("Ando") paid the Company $17.4
million in cash and LTX Common Stock for the rights to manufacture, market and
develop LTX's Fusion product for Japanese customers. The Company recognized $7.4
million of revenue during fiscal 1998 for the sale of its marketing and
development rights. The Company deferred $10.0 million of revenue related to the
manufacturing rights and transfer of technology knowledge. The $10.0 million was
recognized on a percentage of completion basis over the period in which the
Company completes the transfer of the manufacturing and technology rights. The
Company recognized $8.5 million of the deferred revenue in fiscal 1999 and has
recognized the remaining $1.5 million in the first quarter of fiscal 2000. In
addition, the Company will receive future royalty payments, which will be
recognized as revenue in the period earned.

Income Taxes

Deferred income taxes are recorded for temporary differences between the
financial reporting and tax basis of assets and liabilities. Research and
development tax credits are recognized for financial reporting purposes to the
extent that they can be used to reduce the tax provision. The Company has not
provided for federal income taxes on the cumulative undistributed earnings of
its foreign subsidiaries, which were not significant, in the past since it
reinvested those earnings. At October 31, 1999, most of the Company's foreign
subsidiaries had accumulated deficits.

Net Income (Loss) per Share

In July 1998, the Company adopted Statement of Financial Accounting Standards,
"Earnings Per Share" (SFAS 128). All previously reported earnings per share
information presented have been restated to reflect the impact of adopting SFAS
128. Under SFAS 128, basic net income (loss) per common share is computed by
dividing net income (loss) available to common stockholders by the weighted
average number of common shares outstanding for the period. Diluted income
(loss) per common share reflects the maximum dilution that would have resulted
from the assumed exercise and share repurchase related to dilutive stock options
and is computed by dividing net income (loss) by the weighted average number of
common shares and all dilutive securities outstanding.

A reconciliation between basic and diluted earnings per share is as follows:

</TABLE>

There were no options outstanding that were excluded in the above calculation of
diluted earnings per share as of October 31, 1999.  The impact of stock option
and warrants was not used in the calculation of the October 31, 1998 diluted EPS
as the Company was in a net loss position.

Inventories

Inventories are stated at the lower of cost (first-in, first-out) or market and
include material, labor and manufacturing overhead.  Inventories consisted of
the following at:

Comprehensive Income

In August 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 130, "Reporting Comprehensive Income".
The statement requires comprehensive income to be reported with the same
prominence as other financial statements.  Comprehensive income would include
any unrealized gains or losses on available-for-sale securities, foreign
currency translation adjustments and minimum pension liability adjustments.  The
effect of SFAS 130 is immaterial to the Company's financial results.

                                       6

Recent Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board also issued Statement of
Financial Accounting Standards No. 131, "Disclosures About Segments of an
Enterprise and Related Information" (SFAS 131). The statement is effective for
fiscal 1999. SFAS 131 changes the definition and reporting of segments and
requires disclosure by operating segment of information such as profit and loss,
assets and capital expenditures, major customers and types of products from
which revenues are derived, (see Note 9).

In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities". This statement establishes accounting and
reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded in the
balance sheet as either an asset or liability measured at its fair value. The
statement requires that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met. Special
accounting for qualifying hedges allows a derivative's gains and losses to
offset related results on the hedged item in the income statement, and requires
that a company must formally document, designate, and assess the effectiveness
of transactions that receive hedge accounting. SFAS No. 133 is effective for
fiscal years beginning after June 15, 2000. A company may also implement the
statement as of the beginning of any fiscal quarter after issuance (that is,
fiscal quarters beginning June 16, 1998 and thereafter). SFAS No. 133 cannot be
applied retroactively. SFAS No. 133 must be applied to (a) derivative
instruments and (b) certain derivative instruments embedded in hybrid contracts
that were issued, acquired, or substantively modified after December 31, 1997
(and, at the company's election, before January 1, 1998). This statement could
increase volatility in earnings and other comprehensive income for companies
with applicable contracts. The Company is in the process of quantifying the
impact of adopting SFAS No. 133 on its financial statements and has not
determined the timing of or method of adoption.

Interest Expense and Income

Interest expense and income were as follows:

Results of Operations

Three Months Ended October 31, 1999 Compared
to the Three Months Ended October 31, 1998

Net sales for the three months ended October 31, 1999 increased 122% to $60.0
million as compared to $27.0 million in the same quarter of the prior year.  Net
sales included $1.5 million of deferred revenue from the Company's Fusion
alliance with Ando Electric Co., Ltd. All of the $10.0 million of deferred
revenue from the Fusion alliance with Ando has been recognized.  Geographically,
sales to customers outside of North America were 80% and 54% of total net sales
in the three months ended October 31, 1999 and 1998, respectively.  The increase
was due in part to sales to domestic semiconductor producers, which shipped to
international sites.  Service revenues accounted for $7.4 million or 12.3% and
$6.8 million or 25.2% for the three months ended October 31, 1999 and 1998,
respectively.

The gross profit margin was 39.6% of net sales in the three months ended October
31, 1999, compared to 26.7% of net sales in the same quarter of the prior year.
The increase is a result of a higher level of sales relative to fixed
manufacturing costs and improved product margins due to shipments of the
Company's Fusion test systems, which carry a higher gross margin than the prior
generation systems.

Engineering and product development expenses were $7.8 million, or 13.0% of net
sales, in the three months ended October 31, 1999, as compared to $6.0 million,
or 22.2% of net sales, in the same quarter of the prior year.  The increase in
expenditure is principally a result of a higher level of development expenses
and key account support costs for the Company's Fusion product line.

Selling, general and administrative expenses were $8.7 million, or 14.5% of net
sales, in the three months ended October 31, 1999, as compared to $7.9 million,
or 29.3% of net sales, in the same quarter of the prior year. The increase in
the selling, general and administrative expenses of $0.8 million is related to
the development of the Fusion product line and support of key account wins.

Net interest expense was $0.4 million in the three months ended October 31,
1999, as compared to net interest income of $0.2 million in the same quarter in
the prior year and occurred because of the increase in the Company's bank debt
outstanding.

The Company had no tax provision for the three months ended October 31, 1999 and
1998.  The Company's net operating loss carry forward is sufficient to cover
taxable income for the quarter ended October 31, 1999.

                                      10
<PAGE>

Net income was $6.9 million, or $0.17 per share, in the three months ended
October 31, 1999.  The Company had a net loss of $(6.9) million or $(0.19) per
share, in the same quarter of the prior year.

Liquidity and Capital Resources

At October 31, 1999, the Company had $93.5 million in cash and equivalents and
working capital of $134.0 million, as compared to $19.9 million of cash and
equivalents and $47.9 million of working capital at July 31, 1999.  The increase
in cash balance was a result of proceeds from a common stock offering totaling
approximately $80.0 million, which was completed in October 1999.

Accounts receivable from trade customers were $52.6 million at October 31, 1999,
as compared to $37.0 million at July 31, 1999.  The principal reason for the
increase is a result of increasing sales revenue for Fusion products to new and
existing accounts. The reserve for sales returns allowances and doubtful
accounts was $1.8 million or 3.3% of gross accounts receivable on October 31,
1999 and $2.2 million or 5.6% of gross accounts receivable on July 31, 1999. The
major reason for the decrease in the reserve balance was due to write offs of
specifically identified accounts.

Inventories increased by $6.5 million to $55.1 million at October 31, 1999 as
compared to $48.6 million at July 31, 1999. The increase is directly
attributable to the production ramp in the Fusion product line as sales in that
line have increased sequentially each quarter since the quarter ending October
31, 1998.

On October 1, 1999, the Company renegotiated its $10.0 million domestic credit
facility with its current lender. The facility is secured by all assets of the
Company and bears interest at the bank's prime rate plus 0.5%.  Borrowing
availability under the facility is based on a formula of eligible domestic
accounts receivable.  In addition, the Company entered into an agreement with
the same bank that provided the Company with a $5.0 million line of credit that
bears interest at prime plus 0.5%.  Borrowing availability under this facility
is based on a formula of eligible foreign accounts receivable and inventories
and is guaranteed by the Export-Import Bank of the United States.  Outstanding
borrowings at October 31, 1999 were $6.3 million under the domestic credit
facility and $5.0 million under the foreign accounts receivable line facility.

The accrued liabilities for restructuring activity of $2.3 million remained
unchanged from July 31, 1999. This relates to the estimated cost to upgrade
products due to the transition to the Fusion product line. The Company
anticipates this activity will be completed by July 31, 2000.

The Company anticipates that cash flow from operations combined with the recent
equity offering proceeds and credit facility enhancements will be adequate to
fund the Company's currently proposed operating activities for the next twelve
months.

Year 2000

A discussion of the impact of the Year 2000 to the Company appears under the
heading "Business Risks" below.

BUSINESS RISKS

This report includes or incorporates forward-looking statements that involve
substantial risks and uncertainties and fall within the meaning of Section 27A
of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of
1934. You can identify these forward-looking statements by our use of the words
"believes," "anticipates," "plans," "expects," "may," "will," "would,"

whether in the negative or affirmative. We cannot guarantee that we actually
will achieve these plans, intentions or expectations. Actual results or events
could differ materially from the plans, intentions and expectations disclosed in
the forward-looking statements we make. We have included important factors in
the cautionary statements, particularly under the heading "Business Risks,"
which we believe could cause our actual results to differ materially from the
forward-looking statements that we make. We do not assume any obligation to
update any forward-looking statement we make.

Our Sole Market Is the Highly Cyclical Semiconductor Industry, Which Causes a
Cyclical Impact on Our Financial Results.

We sell capital equipment to companies that design, manufacture, assemble, and
test semiconductor devices. The semiconductor industry is highly cyclical,
causing in turn a cyclical impact on our financial results. Any significant
downturn in the markets for our customers' semiconductor devices or in general
economic conditions would likely result in a reduction in demand for our
products and would hurt our business.

Most recently, our revenue and operating results declined in fiscal 1998 as a
result of a sudden and severe downturn in the semiconductor industry
precipitated by the recession in several Asian countries. Downturns in the
semiconductor test equipment industry have been characterized by diminished
product demand, excess production capacity and accelerated erosion of selling
prices. We believe the markets for newer generations of devices, including
system-on-a-chip ("SOC"), will also experience similar characteristics. In the
past, we have experienced delays in commitments, delays in collecting accounts
receivable and significant declines in demand for our products during these
downturns, and we cannot be certain that we will be able to maintain or exceed
our current level of sales. Additionally, as a capital equipment provider, our
revenue is driven by the capital expenditure budgets and spending patterns of
our customers who often delay or accelerate purchases in reaction to variations
in their businesses. Because a high proportion of our costs are fixed, we are
limited in our ability to reduce expenses quickly in response to revenue
shortfalls. In a contraction, we may not be able to reduce our significant fixed
costs, such as continued investment in research and development and capital
equipment requirements.

Our Sales and Operating Results Have Fluctuated Significantly From Period to
Period, Including From One Quarter to Another, and They May Continue to Do So.

Our quarterly and annual operating results are affected by a wide variety of
factors that could adversely affect sales or profitability or lead to
significant variability in our operating results or our stock price. This may be
caused by a combination of factors, including the following:

     .    sales of a limited number of test systems account for a substantial
          portion of our net sales in any particular fiscal quarter, and a small
          number of transactions could therefore have a significant impact;

     .    order cancellations by customers;

     .    lower gross margins in any particular period due to changes in:

          -- our product mix,

                                      12
<PAGE>

          -- the configurations of test systems sold, or

          -- the customers to whom we sell these systems;

     .    the high selling prices of our test systems (which typically result in
          a long selling process); and

     .    changes in the timing of product orders due to:

          -- unexpected delays in the introduction of products by our customers,

          -- shorter than expected lifecycles of our customers' semiconductor
             devices, or

          -- uncertain market acceptance of products developed by our customers.

We cannot predict the impact of these and other factors on our sales and
operating results in any future period. Results of operations in any period,
therefore, should not be considered indicative of the results to be expected for
any future period. Because of this difficulty in predicting future performance,
our operating results may fall below expectations of securities analysts or
investors in some future quarter or quarters. Our failure to meet these
expectations would likely adversely affect the market price of our common stock.

We May Not Be Able to Deliver Custom Hardware Options and Software Applications
to Satisfy Specific Customer Needs in a Timely Manner.

We must develop and deliver customized hardware and software to meet our
customers' specific test requirements. Our test equipment may fail to meet our
customers' technical or cost requirements and may be replaced by competitive
equipment or an alternative technology solution. Our inability to provide a test
system that meets requested performance criteria when required by a device
manufacturer would severely damage our reputation with that customer. This loss
of reputation may make it substantially more difficult for us to sell test
systems to that manufacturer for a number of years. We have, in the past,
experienced delays in introducing some of our products and enhancements.

The Market for Semiconductor Test Equipment is Highly Concentrated, and We Have
Limited Opportunities to Sell Our Products.

The semiconductor industry is highly concentrated, and a small number of
semiconductor device manufacturers and contract assemblers account for a
substantial portion of the purchases of semiconductor test equipment generally,
including our test equipment. Our customers may cancel orders with few or no
penalties. If a major customer reduces orders for any reason, our revenues,
operating results, and financial condition will be hurt. In addition, our
ability to increase our sales will depend in part upon our ability to obtain
orders from new customers. Semiconductor manufacturers select a particular
vendor's test system for testing the manufacturer's new generations of devices
and make substantial investments to develop related test program software and
interfaces. Once a manufacturer has selected one test system vendor for a
generation of devices, that manufacturer is more likely to purchase test systems
from that vendor for that generation of devices, and, possibly, subsequent
generations of devices as well.

                                      13
<PAGE>

Our Future Rate of Growth is Highly Dependent on the Growth of the SOC Market.

In 1996, we refocused our business strategy on the development of our Fusion HF
product, which is primarily targeted towards addressing the needs of the SOC
market. If the SOC market fails to grow as we expect, our ability to sell our
Fusion HF product will be hampered.


Our Market Is Highly Competitive, and We Have Limited Resources to Compete.

The test equipment industry is highly competitive in all areas of the world.
Many other domestic and foreign companies participate in the markets for each of
our products, and the industry is highly competitive. Our principal competitors
in the market for semiconductor test equipment are Agilent Technologies
(formerly a division of Hewlett-Packard), Credence Systems, Schlumberger
Limited, and Teradyne. Most of these major competitors have substantially
greater financial resources and more extensive engineering, manufacturing,
marketing, and customer support capabilities.

We expect our competitors to enhance their current products and to introduce new
products with comparable or better price and performance. The introduction of
competing products could hurt sales of our current and future products. In
addition, new competitors, including semiconductor manufacturers themselves, may
offer new testing technologies, which may in turn reduce the value of our
product lines. Increased competition could lead to intensified price-based
competition, which would hurt our business and results of operations. Unless we
are able to invest significant financial resources in developing products and
maintaining customer support centers worldwide, we may not be able to compete.

Development of Our Products Requires Significant Lead-Time, and We May Fail to
Correctly Anticipate the Technical Needs of Our Customers.

Our customers make decisions regarding purchases of our test equipment while
their devices are still in development. Our test systems are used by our
customers to develop, test and manufacture their new devices. We therefore must
anticipate industry trends and develop products in advance of the
commercialization of our customers' devices, requiring us to make significant
capital investments to develop new test equipment for our customers well before
their devices are introduced. If our customers fail to introduce their devices
in a timely manner or the market does not accept their devices, we may not
recover our capital investment through sales in significant volume. In addition,
even if we are able to successfully develop enhancements or new generations of
our products, these enhancements or new generations of products may not generate
revenue in excess of the costs of development, and they may be quickly rendered
obsolete by changing customer preferences or the introduction of products
embodying new technologies or features by our competitors. Furthermore, if we
were to make announcements of product delays, or if our competitors were to make
announcements of new test systems, these announcements could cause our customers
to defer or forego purchases of our existing test systems, which would also hurt
our business.

Our Success Depends on Attracting and Retaining Key Personnel.

                                      14
<PAGE>

Our success will depend on our ability to attract and retain highly qualified
managers and technical personnel. Competition for such specialized personnel is
intense, and it may become more difficult for us to hire or retain them. Our
volatile business cycles only aggravate this problem. Our layoffs in the last
industry downturn could make it more difficult for us to hire or retain
qualified personnel.

Our Dependence on Subcontractors and Sole Source Suppliers May Prevent Us from
Delivering an Acceptable Product on a Timely Basis.

We rely on subcontractors to manufacture many of the components and
subassemblies for our products, and we rely on sole source suppliers for certain
components. Our reliance on subcontractors gives us less control over the
manufacturing process and exposes us to significant risks, especially inadequate
capacity, late delivery, substandard quality, and high costs.

In addition, the manufacture of certain of these components and subassemblies is
an extremely complex process. If a supplier became unable to provide parts in
the volumes needed or at an acceptable price, we would have to identify and
qualify acceptable replacements from alternative sources of supply, or
manufacture such components internally. The process of qualifying subcontractors
and suppliers is a lengthy process. We are dependent on two semiconductor device
manufacturers, Vitesse Semiconductor and Maxtech Components. Each is a sole
source supplier of components manufactured in accordance with our proprietary
design and specifications. We have no written supply agreements with these sole
source suppliers and purchase our custom components through individual purchase
orders.

Our Dependence on International Sales and Non-U.S. Suppliers Involves
Significant Risk.

International sales have constituted a significant portion of our revenues in
recent years, and we expect that this composition will continue. International
sales accounted for 80% of our revenues for the three months ended October 31,
1999 and 54% of our revenues for the quarter ended October 31, 1998.  In
addition, we rely on non-U.S. suppliers for several components of the equipment
we sell. As a result, a major part of our revenues and the ability to
manufacture our products are subject to the risks associated with international
commerce. A reduction in revenues or a disruption or increase in the cost of our
manufacturing materials could hurt our operating results. These international
relationships make us particularly sensitive to changes in the countries from
which we derive sales and obtain supplies. International sales and our
relationships with suppliers may be hurt by many factors, including:

     .    changes in law or policy resulting in burdensome government controls,
          tariffs, restrictions, embargoes or export license requirements;

     .    political and economic instability in our target international
          markets;

     .    longer payment cycles common in foreign markets;

     .    difficulties of staffing and managing our international operations;

     .    less favorable foreign intellectual property laws making it harder to
          protect our technology from appropriation by competitors; and

                                      15

     .    difficulties collecting our accounts receivable because of the
          distance and different legal rules.

In the past, we have incurred expenses to meet new regulatory requirements in
Europe, experienced periodic difficulties in obtaining timely payment from non-
U.S. customers, and been affected by the recession in several Asian countries.

Our foreign sales are typically invoiced and collected in U.S. dollars. A
strengthening in the dollar relative to the currencies of those countries where
we do business would increase the prices of our products as stated in those
currencies and could hurt our sales in those countries. Significant fluctuations
in the exchange rates between the U.S. dollar and foreign currencies could cause
us to lower our prices and thus reduce our profitability. These fluctuations
could also cause prospective customers to push out or delay orders because of
the increased relative cost of our products. In the past, there have been
significant fluctuations in the exchange rates between the dollar and the
currencies of countries in which we do business.

Economic Conditions in Asia May Hurt Our Sales.

Asia is an important region for our customers in the semiconductor industry, and
many of them have operations there. In recent years, Asian economies have been
highly volatile and recessionary, resulting in significant fluctuations in local
currencies and other instabilities. These instabilities may continue or worsen,
which could have a material adverse impact on our financial position and results
of operations, as approximately 45% of our sales in fiscal 1999 were derived
from this region. These conditions may continue or worsen. In light of the
recent economic downturn in Asia, we may not be able to obtain additional orders
and may experience cancellations of orders. If conditions do not continue to
improve, our future financial condition, revenues, and operating results could
be hurt.

We May Not Be Able to Protect Our Intellectual Property Rights.

Our success depends in part on our ability to obtain intellectual property
rights and licenses and to preserve other intellectual property rights covering
our products and development and testing tools. To that end, we have obtained
certain domestic patents and may continue to seek patents on our inventions when
appropriate. We have also obtained certain trademark registrations. To date, we
have not sought patent protection in any countries other than the United States,
which may impair our ability to protect our intellectual property in foreign
jurisdictions. The process of seeking intellectual property protection can be
time consuming and expensive. We cannot ensure that:

     .    patents will issue from currently pending or future applications;

     .    our existing patents or any new patents will be sufficient in scope or
          strength to provide meaningful protection or any commercial advantage
          to us;

     .    foreign intellectual property laws will protect our intellectual
          property rights; or

     .    others will not independently develop similar products, duplicate our
          products or design around our technology.

                                      16
<PAGE>

If we do not successfully enforce our intellectual property rights, our
competitive position could suffer, which could harm our operating results.

We also rely on trade secrets, proprietary know-how and confidentiality
provisions in agreements with employees and consultants to protect our
intellectual property. Other parties may not comply with the terms of their
agreements with us, and we may not be able to adequately enforce our rights
against these people.

Third Parties May Claim We Are Infringing Their Intellectual Property, and We
Could Suffer Significant Litigation Costs, Licensing Expenses or Be Prevented
from Selling Our Products.

Intellectual property rights are uncertain and involve complex legal and factual
questions. We may be unknowingly infringing on the intellectual property rights
of others and may be liable for that infringement, which could result in
significant liability for us. If we do infringe the intellectual property rights
of others, we could be forced to either seek a license to intellectual property
rights of others or alter our products so that they no longer infringe the
intellectual property rights of others. A license could be very expensive to
obtain or may not be available at all. Similarly, changing our products or
processes to avoid infringing the rights of others may be costly or impractical.

We are responsible for any patent litigation costs. If we were to become
involved in a dispute regarding intellectual property, whether ours or that of
another company, we may have to participate in legal proceedings. These types of
proceedings may be costly and time consuming for us, even if we eventually
prevail. If we do not prevail, we might be forced to pay significant damages,
obtain licenses, modify our products or processes, stop making products or stop
using processes.

Our Stock Price Is Volatile.

In the past twelve months, our stock price has ranged from a low of $2.06 to a
high of $16.18. The price of our common stock has been and likely will continue
to be subject to wide fluctuations in response to a number of events and
factors, such as:

     .    quarterly variations in operating results;

     .    variances of our quarterly results of operations from securities
          analyst estimates;

     .    changes in financial estimates and recommendations by securities
          analysts;

     .    announcements of technological innovations, new products, or strategic
          alliances; and

     .    news reports relating to trends in our markets.

In addition, the stock market in general, and the market prices for
semiconductor-related companies in particular, have experienced significant
price and volume fluctuations that often have been unrelated to the operating
performance of the companies affected by these fluctuations. These broad market
fluctuations may adversely affect the market price of our common stock,
regardless of our operating performance.

Year 2000 Problems May Hurt Our Business.

We have established a program to address Year 2000 software failure issues,
which is overseen by a senior manager who updates our officers and directors
regularly. We are currently assessing the Year 2000 compliance of the products
we manufacture, our internal business systems, and the products and internal
business systems of our suppliers. We expect to incur costs of approximately
$400,000 to make our products Year 2000 compliant, most of which is represented
by current engineering staff who have been assigned to the project, and
approximately $300,000 in ensuring compliance of our internal business systems
and those of our suppliers, most of which is represented by current
administrative personnel assigned to the project. Costs related to Year 2000
compliance have been immaterial as of October 31, 1999.

Three product-based teams, employing our engineering product development
process, are in the process of identifying and contacting affected customers to
advise them of non-compliant products. We cannot assure you that our products do
not contain undetected Year 2000 problems. Another team is assessing the Year
2000 compliance of our internal business systems, including facilities, and the
products and internal business systems of our suppliers. This team has
identified all mission-critical systems and third parties and has formulated
remediation plans. We are also developing comprehensive contingency plans if our
remediation plans do not work, which were essentially completed  by October 31,
1999. These contingency plans primarily involve identifying alternative vendors
and suppliers. They may not adequately address our potential Year 2000 problems,
and alternative sources may not in fact be available. Although responses to a
survey of our critical suppliers, vendors and facilities owners indicate that
many of them are Year 2000 compliant, we have not received sufficient
information from all parties about their Year 2000 readiness to assess the
effectiveness of their efforts. We cannot be sure that these entities will
adequately address Year 2000 issues.

If we fail to detect errors or defects in our systems or those of our suppliers,
or if third parties with whom we interact experience Year 2000 problems,
reasonable descriptions of most likely worst case scenarios include the
following:

     .    power, communication and other utility outages at our facilities, in
          particular, our Westwood, Massachusetts facility; and

     .    product component shortages as a result of Year 2000 problems at our
          critical suppliers and vendors.

If any of these were to occur, our business and operations would be hurt.

Quantitative and Qualitative Disclosures About Market Risk

Financial instruments that potentially subject us to concentrations of credit-
risk consist principally of investments in cash equivalents, short-term
investments and trade receivables. We place our investments with high-quality
financial institutions, limit the amount of credit exposure to any one
institution and have established investment guidelines relative to
diversification and maturities designed to maintain safety and liquidity.

Our primary exposures to market risks include fluctuations in interest rates on
our short-term and long-term debt of approximately $33.4 million as of October
31, 1999 and $27.5 million as of

                                      18
<PAGE>

July 31, 1999, and in foreign currency exchange rates. We do not use derivative
financial instruments. We are subject to interest rate risk on our short-term
borrowings under our credit facilities. Our short-term bank debt bears interest
at a variable rate of prime plus 0.5%. Long term debt interest rates are fixed
for the term of the notes.

Foreign Exchange Risk

Operating in international markets involves exposure to movements in currency
exchange rates. Currency exchange rate movements typically also reflect economic
growth, inflation, interest rates, government actions and other factors. We
transact business in various foreign currencies and, accordingly, we are subject
to exposure from adverse movements in foreign currency exchange rates. As
currency exchange rates fluctuate, translation of the statements of operations
of our international businesses into U.S. dollars may affect year-over-year
comparability and could cause us to adjust our financing and operating
strategies. To date, the effect of changes in foreign currency exchange rates on
revenues and operating expenses have not been material. Substantially all of our
revenues are invoiced and collected in U.S. dollars. Our trade receivables
result primarily from sales to semiconductor manufacturers located in North
America, Japan, the Pacific Rim and Europe. In the three months ended October
31, 1999, our revenues derived from shipments outside the United States
constituted 80.0% of our total revenues. Revenues invoiced and collected in
currencies other than U.S. dollars comprises 3% of our last quarter fiscal
revenues. Receivables are from major corporations or are supported by letters of
credit. We maintain reserves for potential credit losses and such losses have
been immaterial.

Based on a hypothetical ten percent adverse movement in interest rates and
foreign currency exchange rates, the potential losses in future earnings, fair
value of risk-sensitive financial instruments, and cash flows are immaterial,
although the actual effects may differ materially from the hypothetical
analysis.

We do not use derivative financial instruments for speculative trading purposes,
nor do we currently hedge our foreign currency exposure to offset the effects of
changes in foreign exchange rates. We intend to assess the need to utilize
financial instruments to hedge currency exposures on an ongoing basis.

Interest Rate Risk

Historically, we have had no material interest rate risk associated with debt
used to finance our operations due to limited borrowings. Subsequent to this
offering, we intend to manage our interest rate exposure using a mix of fixed
and floating interest rate debt and, if appropriate financial derivative
instruments.

On October 31, 1999, $11.3 million was outstanding under our domestic bank
facility bearing interest at a rate of 8.5%. Based on this balance, an immediate
change of 1% in the interest rate would cause a change in interest expense of
approximately $63,000 on an annual basis. Our objective in maintaining these
variable rate borrowings is the flexibility obtained regarding early repayment
without penalties and lower overall cost as compared with fixed-rate borrowings.

                          LOAN AND SECURITY AGREEMENT


     This LOAN AND SECURITY AGREEMENT (this "Agreement") dated __________, 1999,
between SILICON VALLEY BANK , a California-chartered bank, with its principal
place of business at 3003 Tasman Drive, Santa Clara, California 95054 and with a
loan production office located at Wellesley Office Park, 40 William Street,
Suite 350, Wellesley, Massachusetts 02481, doing business under the name
"Silicon Valley East" ("Bank") and LTX CORPORATION, a Massachusetts corporation
with its chief executive office located at LTX Park at University Avenue,
Westwood, Massachusetts 02090 ("Borrower"), provides the terms on which Bank
shall lend to Borrower and Borrower shall repay Bank. The parties agree as
follows:

     1      ACCOUNTING AND OTHER TERMS
            --------------------------

     Accounting terms not defined in this Agreement shall be construed following
GAAP.  Calculations and determinations must be made following GAAP, consistently
applied.  The term "financial statements" includes the notes and schedules.  The
terms "including" and "includes" always mean "including (or includes) without
limitation" in this or any Loan Document.  Capitalized terms in this Agreement
shall have the meanings set forth in Section 13.  This Agreement shall be
construed to impart upon Bank a duty to act reasonably at all times.

     2      LOAN AND TERMS OF PAYMENT
            -------------------------

     2.1    Credit Extensions.  Borrower shall pay Bank the unpaid principal
            ------------------
amount of all Credit Extensions and interest on the unpaid principal amount of
the Credit Extensions as and when due in accordance with this Agreement.

     2.1.1  Revolving Advances.
            ------------------

            (a) Bank shall make Advances not exceeding (i) the Committed
Revolving Line or the Borrowing Base, whichever is less, minus (ii) the amount
of all outstanding Letters of Credit (including drawn but unreimbursed Letters
of Credit), minus (iii) the FX Reserve, and minus (iv) the amount of outstanding
advances in excess of $5,000,000.00 made under the A/R Purchase Agreement, but
only to the extent not sufficiently reserved therefore under the EXIM Agreement
as determined by the Borrowing Base Certificate to be delivered to the Bank.
Amounts borrowed under this Section may be repaid and reborrowed during the term
of this Agreement.

            (b) To obtain an Advance, Borrower must notify Bank by facsimile or
telephone by 3:00 p.m. Eastern time on the Business Day the Advance is to be
made. Borrower must promptly confirm the notification by delivering to Bank the
Payment/Advance Form attached as Exhibit B. Bank shall credit Advances to
Borrower's deposit account. Bank may make Advances under this Agreement based on
instructions from a Responsible Officer or his or her designee (as designated in
writing by a Responsible Officer) or without instructions if the Advances are
necessary to meet Obligations which have become due. Bank may rely on any
telephone notice given by a person whom Bank believes is a Responsible Officer
or designee. Borrower shall indemnify Bank for any loss Bank suffers due to the
foregoing reliance.

            (c) The Committed Revolving Line terminates on the Revolving
Maturity Date, when all Advances are immediately payable.

     2.1.2  Letters of Credit.  Bank shall issue or have issued Letters of
            -----------------
Credit for Borrower's account not exceeding (i) the lesser of the Committed
Revolving Line or the Borrowing Base minus (ii) the outstanding principal
balance of the Advances, but the face amount of outstanding Letters of Credit
(including drawn but unreimbursed Letters of Credit and any Letter of Credit
Reserve) may not exceed Ten Million Dollars ($10,000,000.00).  Each Letter of
Credit shall expire no later than 180 days after the Revolving Maturity Date
provided Borrower's Letter of Credit reimbursement obligation is secured by cash
on terms acceptable to Bank at any time after the Revolving Maturity Date if the
term of this Agreement is not extended by Bank.

                                      -1-
<PAGE>

     2.1.3 Foreign Exchange Sublimit. If there is availability under the
           -------------------------
Committed Revolving Line and the Borrowing Base, then Borrower may enter in
foreign exchange forward contracts with the Bank under which Borrower commits to
purchase from or sell to Bank a set amount of foreign currency more than one
business day after the contract date (the "FX Forward Contract"). Bank shall
subtract 10% of each outstanding FX Forward Contract (the "FX Reserve") from the
foreign exchange sublimit which is a maximum of Five Million Dollars
($5,000,000.00). The total FX Forward Contracts at any one time may not exceed
10 times the amount of the FX Reserve. Bank may terminate the FX Forward
Contracts if an Event of Default occurs.

     2.2   Overadvances.  If Borrower's Obligations under Section 2.1.1, 2.1.2
           ------------
and 2.1.3 exceed the lesser of either (i) the Committed Revolving Line or (ii)
the Borrowing Base, Borrower must immediately pay in cash to Bank the excess.
In addition, if at any time or for any reason, the aggregate amount of
obligations owed by the borrower to the Bank under this Agreement, the EXIM
Agreement, and the A/R Purchase Agreement exceed Twenty Million Dollars
($20,000,000.00), Borrower shall immediately pay to Bank, in cash, the amount of
such excess.

     2.3   Interest Rate; Payments.
           -----------------------

           (a) Interest Rate. Advances accrue interest on the outstanding
principal balance at a per annum rate one half of one percentage point (0.50%)
above the Prime Rate.  After an Event of Default, Obligations accrue interest at
three (3%) percent above the rate effective immediately before the Event of
Default.  The interest rate increases or decreases when the Prime Rate changes.
Interest is computed on a 360 day year for the actual number of days elapsed.

           (b) Payments.  Interest is payable on the first (1/st/) day of each
month.  Bank may debit any of Borrower's deposit accounts including Account
Number __________ for principal and interest payments or any amounts Borrower
owes Bank. Bank shall notify Borrower in writing when it debits Borrower's
accounts.  These debits are not a set-off.  Payments received after 12:00 noon
Eastern time are considered received at the opening of business on the next
Business Day.  When a payment is due on a day that is not a Business Day, the
payment is due the next Business Day and additional fees or interest accrue.

     2.4   Fees.  Borrower shall pay to Bank: All Bank Expenses (including
           ----
reasonable attorneys' fees and expenses) incurred through and after the Closing
Date when due.

     3     CONDITIONS OF LOANS
           -------------------

     3.1   Conditions Precedent to Initial Credit Extension.  The obligation of
           ------------------------------------------------
Bank to make the initial Credit Extension is subject to the condition precedent
that Bank shall have received, in form and substance satisfactory to Bank, the
following:

           (a)  this Agreement;

           (b) a certificate of the Clerk of Borrower with respect to articles,
     bylaws, incumbency and resolutions authorizing the execution and delivery
     of this Agreement;

           (c) an intellectual property security agreement covering intellectual
     property;

           (d) an opinion of Borrower's counsel;

           (e) financing statements (Forms UCC-1);

           (f)  insurance certificate;

           (g) payment of the fees and Bank Expenses then due specified in

     Section 2.4 hereof;

                                      -2-
<PAGE>

           (h) Certificate of Foreign Qualification (if applicable); and

           (i) such other documents, and completion of such other matters, as
     Bank may reasonably deem necessary or appropriate.

     3.2   Conditions Precedent to all Credit Extensions.  Bank's obligations to
           ---------------------------------------------
make each Credit Extension, including the initial Credit Extension, is subject
to the following:

           (a) timely receipt of any Payment/Advance Form; and

           (b) the representations and warranties in Section 5 must be
materially true on the date of the Payment/Advance Form and on the effective
date of each Credit Extension and no Event of Default may have occurred and be
continuing, or result from the Credit Extension. Each Credit Extension is
Borrower's representation and warranty on that date that the representations and
warranties in Section 5 remain true.

     4     CREATION OF SECURITY INTEREST
           -----------------------------

     4.1   Grant of Security Interest.  Borrower grants Bank a continuing
           --------------------------
security interest in all presently existing and later acquired Collateral to
secure all Obligations (which shall include, without limitation, all obligations
of the Borrower under the EXIM Agreement) and performance of each of Borrower's
duties under the Loan Documents and EXIM Agreement. Any security interest shall
be a first priority security interest in the Collateral. Bank may place a "hold"
on any deposit account pledged as Collateral. If the Agreement is terminated,
Bank's lien and security interest in the Collateral shall continue until
Borrower fully satisfies its Obligations. Notwithstanding the foregoing, it is
expressly acknowledged and agreed that the security interest created in this
Agreement only with respect to EXIM Eligible Foreign Accounts and Exim Eligible
Inventory (as each such term is defined in the EXIM Agreement) is subject to and
subordinate to the security interest granted to the Bank in the EXIM Agreement
with respect to such Eligible Foreign Accounts and Exim Eligible Inventory, but
only to the extent any Advances are actually made to the Borrower based upon
such Eligible Foreign Accounts and Exim Eligible Inventory.

     5     REPRESENTATIONS AND WARRANTIES
           ------------------------------

     Borrower represents and warrants as follows:

     5.1   Due Organization and Authorization.  Borrower and each Subsidiary is
           ----------------------------------
duly existing and in good standing in its state of formation and qualified and
licensed to do business in, and in good standing in, any state in which the
conduct of its business or its ownership of property requires that it be
qualified, except where the failure to do so could not reasonably be expected to
cause a Material Adverse Change.

     The execution, delivery and performance of the Loan Documents have been
duly authorized, and do not conflict with Borrower's organizational documents,
nor constitute an event of default under any material agreement by which
Borrower is bound.  Borrower is not in default under any agreement to which or
by which it is bound in which the default could reasonably be expected to cause
a Material Adverse Change.

     5.2   Collateral.  Borrower has good title to the Collateral, free of Liens
           ----------
except Permitted Liens.  The Eligible Accounts are bona fide, existing
obligations, and the service or property has been performed or delivered to the
account debtor or its agent for immediate shipment to and unconditional
acceptance by the account debtor.  Borrower has no notice of any actual or
imminent Insolvency Proceeding of any account debtor whose accounts are an
Eligible Account in any Borrowing Base Certificate.  All Inventory is in all
material respects of good and marketable quality, free from material defects.

     5.3   Litigation.  Except as shown in the Schedule, there are no actions or
           ----------
proceedings pending or, to Borrower's knowledge, threatened by or against
Borrower or any Subsidiary in which an adverse decision could reasonably be
expected to cause a Material Adverse Change.

                                      -3-
<PAGE>

     5.4   No Material Adverse Change in Financial Statements.  All consolidated
           --------------------------------------------------
financial statements for Borrower and any Subsidiary delivered to Bank fairly
present in all material respects Borrower's consolidated financial condition and
Borrower's consolidated results of operations.  There has not been any material
deterioration in Borrower's consolidated financial condition since the date of
the most recent financial statements submitted to Bank.

     5.5   Solvency.  Borrower is able to pay its debts (including trade debts)
           --------
as they mature.

     5.6   Regulatory Compliance.  Borrower is not an "investment company" or a
           ---------------------
company "controlled" by an "investment company" under the Investment Company
Act.  Borrower is not engaged as one of its important activities in extending
credit for margin stock (under Regulations T and U of the Federal Reserve Board
of Governors).  Borrower has complied in all material respects with the Federal
Fair Labor Standards Act.  Borrower has not violated any laws, ordinances or
rules, the violation of which could reasonably be expected to cause a Material
Adverse Change.  None of Borrower's or any Subsidiary's properties or assets has
been used by Borrower or any Subsidiary or, to the best of Borrower's knowledge,
by previous Persons, in disposing, producing, storing, treating, or transporting
any hazardous substance other than legally.  Borrower and each Subsidiary has
timely filed all required tax returns and paid, or made adequate provision to
pay, all material taxes, except those being contested in good faith with
adequate reserves under GAAP.  Borrower and each Subsidiary has obtained all
consents, approvals and authorizations of, made all declarations or filings
with, and given all notices to, all government authorities that are necessary to
continue its business as currently conducted except where the failure to make
such declarations, notices or filings would  not reasonably be expected to
result in a Material Adverse Change.

     5.7    Subsidiaries.  Except as disclosed in the Schedule, Borrower does
            ------------
not own any stock, partnership interest or other equity securities except for
Permitted Investments.

     5.8    Full Disclosure.  No representation, warranty or other statement of
            ---------------
Borrower in any certificate or written statement given to Bank contains any
untrue statement of a material fact or omits to state a material fact necessary
to make the statements contained in the certificates or statements not
misleading.

     6      AFFIRMATIVE COVENANTS

     9    BANK'S RIGHTS AND REMEDIES
          --------------------------

     9.1  Rights and Remedies. When an Event of Default occurs and continues
          -------------------
Bank may, without notice or demand, do any or all of the following:

          (a) Declare all Obligations (including, without limitation, all
     obligations under the EXIM Agreement) immediately due and payable (but if
     an Event of Default described in Section 8.5 occurs all Obligations are
     immediately due and payable without any action by Bank);

          (b) Stop advancing money or extending credit for Borrower's benefit
     under this Agreement or under any other agreement between Borrower and
     Bank;

          (c) Settle or adjust disputes and claims directly with account debtors
     for amounts, on terms and in any order that Bank considers advisable;

          (d) Make any payments and do any acts it considers necessary or
     reasonable to protect its security interest in the Collateral.  Borrower
     shall assemble the Collateral if Bank requests and make it available as
     Bank designates.  Bank may enter premises where the Collateral is located,
     take and maintain possession of any part of the Collateral, and pay,
     purchase, contest, or compromise any Lien which appears to be prior or
     superior to its security interest and pay all expenses incurred. Borrower
     grants Bank a license to enter and occupy any of its premises, without
     charge, to exercise any of Bank's rights or remedies;

          (e) Apply to the Obligations any (i) balances and deposits of Borrower
     it holds, or (ii) any amount held by Bank owing to or for the credit or the
     account of Borrower;

          (f) Ship, reclaim, recover, store, finish, maintain, repair, prepare
     for sale, advertise for sale, and sell the Collateral; and

          (g) Dispose of the Collateral according to the Code.

     9.2  Power of Attorney. Borrower hereby irrevocably appoints Bank as its
          -----------------
lawful attorney-in-fact, to be effective only upon the occurrence and during the
continuance of an Event of Default, to: (i) endorse Borrower's name on any
checks or other forms of payment or security in respect of any of the
Collateral; (ii) sign Borrower's name on any invoice or bill of lading for any
Accounts or drafts against account debtors, (iii) make, settle, and adjust all
claims under Borrower's insurance policies; (iv) settle and adjust disputes and
claims about the Accounts directly with account debtors, for amounts and on
terms Bank determines reasonable, and (v) transfer the Collateral into the name
of Bank or a third party as the Code permits. Borrower hereby appoints Bank its
power of attorney to sign Borrower's name on any documents necessary to perfect
or continue the perfection of any security interest regardless of whether an
Event of Default has occurred until all Obligations have been satisfied in full
and Bank is under no further obligation to make Credit Extensions hereunder.
Bank's foregoing appointment as Borrower's attorney in fact, and all of Bank's
rights and powers, coupled with an interest, are irrevocable until all
Obligations have been fully repaid and performed and Bank's obligation to
provide Credit Extensions terminates.

     9.3  Accounts Collection. When an Event of Default occurs and continues,
          -------------------
Bank may notify any Person owing Borrower money of Bank's security interest in
the funds and verify the amount of the Account.  Borrower must collect all
payments in trust for Bank and, if requested by Bank, immediately deliver the
payments to Bank in the form received from the account debtor, with proper
endorsements for deposit.

     9.4  Bank Expenses. If Borrower fails to obtain insurance as required
          -------------
under Section 6.5 or to pay any amount or furnish any required proof of payment
to third persons and the Bank, Bank may make all or part of the payment or
obtain such insurance policies required in Section 6.5, and take any action
under the policies Bank deems prudent. Any amounts paid by Bank as provided
herein are Bank Expenses and are immediately due and payable, bearing interest
at the then applicable rate and secured by the Collateral. No payments by Bank
are deemed an

                                      -8-
<PAGE>

agreement to make similar payments in the future or Bank's waiver of any Event
of Default.

     9.5  Bank's Liability for Collateral. So long as the Bank complies with
          -------------------------------
reasonable banking practices regarding the safekeeping of collateral, the Bank
shall not be liable or responsible for: (a) the safekeeping of the Collateral;
(b) any loss or damage to the Collateral; (c) any diminution in the value of the
Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or
other person.  Borrower bears all risk of loss, damage or destruction of the
Collateral.

     9.6  Remedies Cumulative. Bank's rights and remedies under this Agreement,
          -------------------
the Loan Documents, and all other agreements are cumulative.  Bank has all
rights and remedies provided under the Code, by law, or in equity. Bank's
exercise of one right or remedy is not an election, and Bank's waiver of any
Event of Default is not a continuing waiver. Bank's delay is not a waiver,
election, or acquiescence. No waiver is effective unless signed by Bank and then
is only effective for the specific instance and purpose for which it was given.

     9.7  Demand Waiver. Borrower waives demand, notice of default or dishonor,
          -------------
notice of payment and nonpayment, notice of any default, nonpayment at maturity,
release, compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guaranties held by Bank on which Borrower is
liable.

           ------------------
     Agreement, Bank agrees to make Advances to Borrower in an amount not to
     exceed the Exim Committed Line or the Borrowing Base, whichever is less,
     minus the amount of outstanding advances in excess of $5,000,000.00 made
     -----
     under the A/R Purchase Agreement, but only to the extent not sufficiently
     reserved therefore under the Domestic Agreement as determined by the
     Borrowing Base Certificate to be delivered to the Bank.

     To evidence the Advances, Borrower shall execute and deliver to Bank on the
date hereof a promissory note (the "Note") in substantially the form attached
hereto as Exhibit B.
          ---------

     Whenever Borrower desires an Advance, Borrower will notify Bank by

Business Day that the Advance is to be made.  Each such notification shall be
promptly confirmed by a Payment/Advance Form in substantially the form of

Exhibit C hereto together with any additional documentation required under the
- ---------
Borrower Agreement, including without limitation, as set forth in Section 2.03
of the Borrower Agreement.  In addition to the procedure set forth in the
preceding sentence, Bank is authorized to make Advances under this Exim
Agreement, based upon written instructions received from a Responsible Officer
or without instructions if in Bank's discretion such Advances are necessary to
meet Obligations which have become due and remain unpaid.  Bank shall be
entitled to rely on any telephonic notice given by a person who Bank reasonably
believes to be a Responsible Officer or a designee (as designated in writing by
a Responsible Officer) thereof, and Borrower shall indemnify and hold Bank
harmless for any damages or loss suffered by Bank as a result of such reliance.
Bank will credit the amount of Advances made under this Section 2.1.1 to
Borrower's deposit account.  Amounts borrowed pursuant to this Section 2.1.1 may
be repaid at any time and re-borrowed at any time during the term of this Exim
Agreement so long as no Event of Default has occurred and is continuing.

     2.2  Overadvances.  If, at any time or for any reason, the amount of
          ------------
Obligations pursuant to this Exim Agreement owed by Borrower to Bank pursuant to
Section 2.1 of this Exim Agreement is greater than the lesser of (i) the
Borrowing Base or (ii) the Exim Committed Line, Borrower shall immediately pay
to Bank, in cash, the amount of such excess.  In addition, if at any time or for
any reason, the aggregate amount of obligations owed by the Borrower to the Bank
under this Exim Agreement, the Domestic Loan Documents, and the A/R Purchase
Agreement exceed Twenty Million Dollars ($20,000,000.00), Borrower shall
immediately pay to Bank, in cash, the amount of such excess. In addition, if at
any time or for any reason, the aggregate amount of Advances made as a result of
Exim Eligible Inventory (as determined by the Borrowing Base Certificate)
exceeds the maximum allowable under Section 2.07(c) of the Borrower Agreement,
the Borrower shall within five (5) calendar days either (i) furnish additional
collateral satisfactory to the Bank which shall not consist of Inventory, or
(ii) pay to Bank, in cash, the amount of such excess

     2.3  Interest Rates, Payments, and Calculations.
          ------------------------------------------

          (a) Interest Rate. Except as set forth in Section 2.3(b), or as
              -------------
specified to the contrary in any Loan Document, any Advances under this Exim
Agreement shall bear interest, on the average daily balance, at a rate equal to
the Prime Rate plus one half of one percent (0.50%) per annum.

          (b) Default Rate. All Obligations shall bear interest, from and after
              ------------
the occurrence of an Event of Default, at a rate equal to the lesser of (i)
three (3%) percentage points above the rate that applied immediately prior to
the occurrence of the Event of Default, and (ii) the maximum interest rate
allowed by applicable law.

          (c) Payments. Interest hereunder shall be due and payable on each
              --------
Payment Date. Bank shall, at its option, charge such interest, all Exim Bank
Expenses, and all Periodic Payments against Borrower's deposit account or
against the Exim Committed Line, in which case those amounts shall thereafter
accrue interest at the rate then applicable hereunder.

          (d) Computation. In the event the Prime Rate is changed from time to
              -----------
time hereafter, the applicable rate of interest hereunder shall be increased or
decreased contemporaneously with such change by an amount equal to such change
in the Prime Rate. All interest chargeable under the Exim Loan Documents shall
be computed on the basis of a three hundred sixty (360) day year for the actual
number of days elapsed.

     2.4  Crediting Payments. The receipt by Bank of any wire transfer of funds,
          ------------------
check, or other item of payment shall be immediately applied to conditionally
reduce Obligations, but shall not be considered a payment on account unless such
wire transfer is of immediately available federal funds and is made to the
appropriate deposit account of Bank or unless and until such check or other item
of payment is honored when presented for payment. Notwithstanding anything to
the contrary contained herein, any payment (other than a wire transfer of
immediately available funds) received by Bank after 12:00 p.m. (noon) Eastern
time shall be deemed to have been received by Bank as of the opening of business
on the immediately following Business Day.

     2.5  Fees.  Borrower shall pay to Bank the following fees:

     4.   CREATION OF SECURITY INTEREST
          -----------------------------

     4.1  Grant of Security Interest.  Borrower grants and pledges to Bank a
          --------------------------
continuing security interest in all presently existing and hereafter acquired or
arising Collateral in order to secure prompt payment of any and all Obligations
(which Obligations shall include, without limitation, all obligations of the
Borrower to the Bank under the Domestic Loan Documents) and in order to secure
prompt performance by Borrower of each of its covenants and duties under the
Exim Loan Documents and Domestic Loan Documents.  Except as set forth in the
Schedule, such security interest constitutes a valid, first priority security
interest in the presently existing Collateral, and will constitute a valid,
first priority security interest in Collateral acquired after the date hereof.
Borrower acknowledges that Bank may place a "hold" on any Deposit Account
pledged as Collateral to secure the Obligations. Notwithstanding termination of
this Agreement, Bank's Lien on the Collateral shall remain in effect for so long
as any Obligations are outstanding.  Notwithstanding the foregoing, it is
expressly acknowledged and agreed that the security interest created in this
Exim Agreement in all of the Collateral, with the exception of both Exim
Eligible Foreign Accounts and Exim Eligible Inventory to the extent any Advances
are actually made by the Bank to the Borrower based upon such Eligible Foreign
Accounts and Exim Eligible Inventory), is subject to and subordinate to the
security interest granted to the Bank in the Domestic Agreement with respect to
the Collateral.

     4.2  Delivery of Additional Documentation Required. Borrower shall from
          ---------------------------------------------
time to time execute and deliver to Bank, at the reasonable request of bank, all
financing statements and other documents that Bank may reasonably request, in
form satisfactory to Bank, to perfect and continue perfected Bank's security
interests in the Collateral and in order to fully consummate all of the
transactions contemplated under the Exim Loan Documents.

     4.3  Power of Attorney.  Effective only upon the occurrence and during the
          -----------------
continuance of an Event of Default, Borrower hereby irrevocably appoints Bank
(and any of Bank's designated officers or employees) as Borrower's true and
lawful attorney, with power to: (a) send requests for verification of Accounts;
(b) endorse Borrower's name on any checks or other forms of payment or security
that may come into Bank's possession; (c) sign the name of Borrower on any of
the documents described in Section 4.2 (regardless of whether an Event of
Default has occurred); (d) sign Borrower's name on any invoice or bill of lading
relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (e) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (f) settle and adjust disputes
and claims respecting the accounts directly with account debtors, for amounts
and upon terms which Bank determines to be reasonable.  The appointment of Bank
as Borrower's attorney-in-fact, and each of Bank's rights and powers, being
coupled with an interest, is irrevocable until all of the Obligations have been
fully repaid and Bank's obligation to provide Advances hereunder is terminated.

     4.4  Right to Inspect.  Each of Bank and Exim Bank (through any of their
          ----------------
respective officers, employees, or agents) shall have the right, upon reasonable
prior notice, from time to time during Borrower's usual business hours, without
causing any disruptions of Borrower's operations (prior to an Event of Default)
to inspect Borrower's Books, facilities and activities, and to check, test, and
appraise the Collateral in order to verify Borrower's financial condition or the
amount, condition of, or any other matter relating to, the Collateral.  Bank
shall conduct annual accounts receivable audits, the results of which audits
shall be satisfactory to Bank.  Borrower will cause its officers and employees
to give their full cooperation and assistance in connection therewith.

     8.   EVENTS OF DEFAULT
          -----------------

     Any one or more of the following events shall constitute an Event of

Default occurs under any of the Domestic Loan Documents or the Borrower
Agreement and as to any default under such other term, provision, condition,
covenant or agreement that can be cured, has failed to cure such default within

default cannot by its nature be cured within the ten (10) day period or cannot

and such default is likely to be cured within a reasonable time, then Borrower
shall have an additional reasonable period (which shall not in any case exceed
thirty (30) days) to attempt to cure such default, and within such reasonable
time period the failure to have cured such default shall not be deemed an Event
of Default (provided that no Advances will be required to be made during such

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

     9.1  Rights and Remedies. Upon the occurrence and during the continuance of

authorized by the Borrower:

          (a) Declare all Obligations, whether evidenced by this Exim Agreement,
     the Domestic Loan Documents, or by any of the other Exim Loan Documents, or
     otherwise, immediately due and payable (provided that upon the occurrence

     Obligations shall become immediately due and payable without any action by
     Bank);

          (b) Cease advancing money or extending credit to or for the benefit of
     Borrower under this Exim Agreement or under any other agreement between
     Borrower and Bank;

<PAGE>

          (e) Without notice to or demand upon Borrower, make such payments and
     do such acts as Bank considers necessary or reasonable to protect its
     security interest in the Collateral. Borrower agrees to assemble the
     Collateral if Bank so requires, and to make the Collateral available to
     Bank as Bank may designate. Borrower authorizes Bank to enter the premises
     where the Collateral is located, to take and maintain possession of the
     Collateral, or any part of it, and to pay, purchase, contest, or compromise
     any encumbrance, charge, or lien which in Bank's determination appears to
     be prior or superior to its security interest and to pay all expenses
     incurred in connection therewith. With respect to any of Borrower's
     premises, Borrower hereby grants Bank a license to enter such premises and
     to occupy the same, without charge, in order to exercise any of Bank's
     rights or remedies provided herein, at law, in equity, or otherwise;

          (f) With notice to the Borrower, set off and apply to the Obligations
     any and all (i) balances and deposits of Borrower held by Bank, or (ii)
     indebtedness at any time owing to or for the credit or the account of
     Borrower held by Bank;

          (g) Ship, reclaim, recover, store, finish, maintain, repair, prepare
     for sale, advertise for sale, and sell (in the manner provided for herein)
     the Collateral. Bank is hereby granted a non-exclusive, royalty-free
     license or other right, solely pursuant to the provisions of this Section
     9.1, to use, without charge, Borrower's labels, patents, copyrights, mask
     works, rights of use of any name, trade secrets, trade names, trademarks,
     service marks, and advertising matter, or any property of a similar nature,
     as it pertains to the Collateral, in completing production of, advertising
     for sale, and selling any Collateral and, to the extent required for Bank's
     exercise of its rights under this Section 9.1, Borrower's rights under all
     licenses and all franchise agreements shall inure to Bank's benefit;

          (h) Sell the Collateral at either a public or private sale, or both,
     by way of one or more contracts or transactions, for cash or on terms, in
     such manner and at such places (including Borrower's premises) as Bank
     determines is commercially reasonable, and apply the proceeds thereof to
     the Obligations in whatever manner or order it deems appropriate; and

          (i) Bank may credit bid and purchase at any public sale, or at any
     private sale as permitted by law.

     Any deficiency that exists after disposition of the Collateral as provided
above will be paid immediately by Borrower.

     9.2  Exim Direction.  Upon the occurrence of an Event of Default, Exim Bank
          --------------
shall have a right to: (i) direct Bank to exercise the remedies specified in
Section 9.1 and (ii) request that Bank accelerate the maturity of any other
loans to Borrower as to which Bank has a right to accelerate.

     9.3  Exim Notification. Bank shall have the right to immediately notify
          -----------------
Exim Bank in writing if it has knowledge of the occurrence of any of the
following events: (1) any failure to pay any amount due under this Exim
Agreement or the Note; (2) the Borrowing Base is less than the sum of
outstanding Advances hereunder; (3) any failure to pay when due any amount
payable to Bank by the Borrower under any loan(s) extended by Bank to Borrower;
(4) the filing of an action for debtor's relief by, against, or on behalf of
Borrower; or (5) any threatened or pending material litigation against Borrower,
or any material dispute involving Borrower.

     In the event that it sends such a notification to Exim Bank, Bank shall
have the right to thereafter send Exim Bank a written report on the status of
the events covered by said notification on each Business Day which occurs every
thirty (30) calendar days after the date of said notification, until such time
as Bank files a claim with Exim Bank or said default or other events have been
cured.  Bank shall not have any obligation to make any Advances following said
notification to Exim Bank, unless Exim Bank gives its written approval thereto.
If directed to do so by Exim Bank, Bank shall have a right promptly to exercise
any rights it may have against Borrower to demand the immediate repayment of all
amounts outstanding under the Exim Loan Documents.

     9.4  Remedies Cumulative.  Bank's rights and remedies under this Exim
          -------------------
Agreement, the Exim Loan Documents, the Domestic Loan Documents and all other
agreements shall be cumulative.  Bank shall have all other rights and remedies
not inconsistent herewith as provided under the Code, by law, or in equity.  No
exercise by Bank of one right or remedy shall be deemed an election, and no
waiver by Bank of any Event of Default on Borrower's part shall be deemed a
continuing waiver.  No delay by Bank shall constitute a waiver, election, or
acquiescence by it. No waiver by Bank shall be effective unless made in a
written document signed on behalf of Bank and then shall be effective only in
the specific instance and for the specific purpose for which it was given

     9.5  Power of Attorney.  Effective only upon the occurrence and during the
          -----------------
continuance of an Event of Default, Borrower hereby irrevocably appoints Bank
(and any of Bank's designated officers, or employees) as Borrower's true and
lawful attorney to: (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (e) settle and adjust disputes
and claims respecting the accounts directly with account debtors, for amounts
and upon terms which Bank determines to be reasonable; and (f) to file, in its
sole discretion, one or more financing or continuation statements and amendments
thereto, relative to any of the Collateral without the signature of Borrower
where permitted by law provided Bank may exercise such power of attorney to sign
the name of Borrower on any of the documents described in Section  regardless of
whether an Event of Default has occurred.  The appointment of Bank as Borrower's
attorney in fact, and each and every one of Bank's rights and powers, being
coupled with an interest, is irrevocable until all of the Obligations have been
fully repaid and performed and Bank's obligation to provide advances hereunder
is terminated.

     9.6  Accounts Collection. Upon the occurrence and during the continuance of
          -------------------
an Event of Default, Bank may notify any Person owing funds to Borrower of
Bank's security interest in such funds and verify the amount of such Account.
Borrower shall collect all amounts owing to Borrower for Bank, receive in trust
all payments as Bank's trustee, and if requested or required by Bank,
immediately deliver such payments to Bank in their original form as received
from the account debtor, with proper endorsements for deposit.

     9.7  Bank Expenses.  If Borrower fails to pay any amounts or furnish any
          -------------
required proof of payment due to third persons or entities, as required under
the terms of this Agreement, then Bank may do any or all of the following:  (a)
make payment of the same or any part thereof; (b) set up such reserves under the
Committed Revolving Line as Bank reasonably deems necessary to protect Bank from
the exposure created by such failure; or (c) obtain and maintain insurance
policies of the type discussed in Section 6.5 of the Domestic Agreement, and
take any action with respect to such policies as Bank deems prudent.  Any
amounts so paid or deposited by Bank shall constitute Bank Expenses, shall be
immediately due and payable and shall bear interest at the then applicable rate
hereinabove provided, and shall be secured by the Collateral.  Any payments made
by Bank shall not constitute an agreement by Bank to make similar payments in
the future or a waiver by Bank of any Event of Default under this Agreement.

     9.8  Bank's Liability for Collateral.  So long as Bank complies with
          -------------------------------
reasonable banking practices, Bank shall not in any way or manner be liable or
responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage
thereto occurring or arising in any manner or fashion from any cause; (c) any
diminution in the value thereof; or (d) any act or default of any carrier,
warehouseman, bailee, forwarding agency, or other person whomsoever.  All risk
of loss, damage or destruction of the Collateral shall be borne by Borrower.

     9.9  Demand; Protest.  Borrower waives demand, protest, notice of protest,
          ---------------
notice of default or dishonor, notice of payment and nonpayment, notice of any

renewal of accounts, documents, instruments, chattel paper, and guarantees at
any time held by Bank on which Borrower may in any way be liable.

                           Revolving Promissory Note
                              (Export-Import Line)


$5,000,000.00                                                  ___________, 1999

     FOR VALUE RECEIVED, the undersigned (the "Borrower"), promises to pay to
the order of Silicon Valley Bank ("Bank"), at such place as the holder hereof
may designate, in lawful money of the United States of America, the aggregate
unpaid principal amount of all advances ("Advances") made by Bank to Borrower,
up to a maximum principal amount of Five Million Dollars ($5,000,000.00), plus
interest on the aggregate unpaid principal amount of such Advances, at the rates
and in accordance with the terms of the Export-Import Bank Loan and Security
Agreement between Borrower and Bank of even date herewith, as amended from time
to time (the "Loan Agreement") on the first calendar day of each month after an
Advance has been made.  The entire principal amount and all accrued interest
shall be due and payable on ___________, 2000, or on such earlier date, as
provided for in the Loan Agreement.

     Borrower irrevocably waives the right to direct the application of any and
all payments at any time hereafter received by Bank from or on behalf of
Borrower, and Borrower irrevocably agrees that Bank shall have the continuing
exclusive right to apply any and all such payments against the then due and
owing obligations of Borrower as Bank may deem advisable.  In the absence of a
specific determination by Bank with respect thereto, all payments shall be
applied in the following order: (a) then due and payable fees and expenses; (b)
then due and payable interest payments and mandatory prepayments; and (c) then
due and payable principal payments and optional prepayments.

     Bank is hereby authorized by Borrower to endorse on Bank's books and
records each Advance made by Bank under this Note and the amount of each payment
or prepayment of principal of each such Advance received by Bank; it being
understood, however, that failure to make any such endorsement (or any errors in
notation) shall not affect the obligations of Borrower with respect to Advances
made hereunder, and payments of principal by Borrower shall be credited to
Borrower notwithstanding the failure to make a notation (or any errors in
notation) thereof on such books and records.

     Borrower promises to pay Bank all reasonable costs and reasonable expenses
including all reasonable attorneys' fees, incurred in such collection or in any
suit or action to collect this Note or in any appeal thereof, unless a final
court of competent jurisdiction finds that the Bank acted with gross negligence
or willful misconduct. Borrower waives presentment, demand, protest, notice of
protest, notice of dishonor, notice of nonpayment, and any and all other notices
and demands in connection with the delivery, acceptance, performance, default or
enforcement of this Note, as well as any applicable statute of limitations.  No
delay by Bank in exercising any power or right hereunder shall operate as a
waiver of any power or right.  Time is of the essence as to all obligations
hereunder.

     This Note is issued pursuant to the Loan Agreement, which shall govern the
rights and obligations of Borrower with respect to all obligations hereunder.

     The law of the Commonwealth of Massachusetts shall apply to this Agreement.
BORROWER ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES,
UNCONDITIONALLY, THE NON-EXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT OF
COMPETENT JURISDICTION IN THE COMMONWEALTH OF MASSACHUSETTS IN ANY ACTION, SUIT,
OR PROCEEDING OF ANY KIND, AGAINST IT WHICH ARISES OUT OF OR BY REASON OF THIS
AGREEMENT; PROVIDED, HOWEVER, THAT IF FOR ANY REASON BANK CANNOT AVAIL ITSELF OF
THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS, BORROWER ACCEPTS JURISDICTION
OF THE COURTS AND VENUE IN SANTA CLARA COUNTY, CALIFORNIA..

     BORROWER WAIVES ITS RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING OUT OF ANY OF THE EXIM LOAN DOCUMENTS OR ANY OF THE
TRANSACTIONS CONTEMPLATED THEREIN, INCLUDING CONTRACT CLAIMS, TORT CLAIMS,

                                      -15-

                                  ----------


Borrower's landlord in its Westwood, Massachusetts facility served Borrower on
December 29, 1998 with a complaint seeking a declaratory judgment, specific
performance and damages for Borrower's alleged breach of its obligations under
the lease agreement with the landlord. The landlord's complaint alleges that
improvements made to the HVAC system in the building in 1995 were unauthorized
and created a lien in violation of the lease as a result of lease financing of
the HVAC system. Borrower and the landlord have entered into an agreement to
restructure the lease, subject to the landlord's refinancing of the building and
Borrower's agreement to purchase the HVAC system and terminate the HVAC lease
financing by November 15, 1999. Upon completion of these transactions, the
parties have agreed to request the court to dismiss the complaint with
prejudice.

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


Borrower owns a 10% interest in a corporate joint venture with FlexTech
Holdings. The joint venture purchased certain assets from Borrower relating to
board repair services for its legacy products.

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


Consistent with Borrower's business strategy to focus on Fusion, Borrower is
seeking to divest itself of its iPTest division. The iPTest division
manufacturers test systems that are used to test specialized components such as
power transistors. The percentage of net sales contributed by iPTest, compared
to total net sales, was 3.0%, or $5.1 million for the fiscal year ended July 31,
1999.

Company and its stockholders by improving the Company's ability to attract and

additional incentive for such individuals to contribute to the Company's future
success. The Plan is intended to be an incentive stock option plan within the
meaning of Section 422 of the Code, but not all Options granted hereunder are
required to be Incentive Options.

3.   Term of the Plan. Options and Restricted Share awards under the Plan may
     ----------------
be granted on or after June 4, 1999, but not later than June 4, 2009.

4.   Stock Subject to the Plan. Subject to the provisions of Section 14 of the
     -------------------------
Plan, the number of shares of the Stock attributable to the exercise of Options
granted under the Plan plus the number the number of shares then issuable upon
exercise of outstanding options granted under the Plan plus the number of
Restricted Shares awarded under the Plan shall at no time exceed 2,100,000
shares. Shares to be issued upon the exercise of Options granted under the Plan
and Restricted Shares may be either authorized but unissued shares or shares
held by the Company in its treasury. If any Option expires or terminates for any
reason without having been exercised in full, the shares not purchased
thereunder shall again be available for Options thereafter to be granted. Each
Director who is not an employee of the Company or a subsidiary thereof shall
receive a Nonstatutory Option to purchase 20,000 shares of Common Stock on the
date on which he or she is first elected to the Board of Directors of the
Company and an additional Nonstatutory Option to purchase 6,000 shares of Common
Stock on the date of each annual meeting at which he or she is re-elected or
after which he continues to serve as a Director. Each Director who is not an
employee of the Company or a subsidiary thereof shall also receive a
Nonstatutory Option to purchase 3,000 shares of Common Stock in each year served
as a chairman of a Committee of the Board of Directors and a Nonstatutory Option
to purchase 1,500 shares of Common Stock in each year

                                       2
<PAGE>

served as a member of a Committee of the Board of Directors, such options to be
issued on the date the Committees are established annually by the Board of
Directors. Each Option granted to a Director under this Section 4 shall have a
Fair Market Value exercise price per share and shall be exercisable,
cumulatively, to the extent of twenty percent of the stock covered thereby on
the first anniversary date of the grant of the Option, thirty-five percent of
the stock covered thereby on the second anniversary date of the grant of the
Option and forty-five percent of the stock covered thereby on the third
anniversary date of the grant of the Option. In the event any Director standing
for re-election is not re-elected to the Board of Directors at any meeting, all
of such Director's unexercisable Options granted prior to the date of that
meeting will become exercisable immediately.

5.   Administration. The Plan shall be administered by the Board of Directors
     --------------
of the Company or by a committee composed of members of the Board (the Board of
Directors or any such committee being hereinafter referred to as the
"Committee"). With respect to directors and Officers eligible to receive Options
or Restricted Shares under this Plan, the Plan shall be administered by a
special committee (the "Special Committee") of the Board of Directors of the
Company all of whom are "Non-Employee Directors" as defined in Rule 16b-
3(b)(2)(i) under Section 16 of the Securities Exchange Act of 1934 and "outside
directors" as defined in Section 162(m) of the Code. Only the Special Committee
may grant Options to directors and Officers eligible to receive Options under
this Plan. Subject to the provisions of the Plan, the Committee or the Special
Committee, as the case may be, shall have complete authority, in its discretion,
to make the following determinations with respect to each Option to be granted
by the Company and all Restricted Shares to be awarded by the Company: (a) the
employee, director or consultant to receive the Option or award; (b) the time of
granting the Option or award; (c) the number of shares subject thereto; (d) the
Option Price; (e) the Option period; and (f) the restrictions. In making such
determinations, the Committee may take into account the nature of the services
rendered by the respective employees, directors and consultants their present
and potential contributions to the success of the Company and its subsidiaries,
and such other factors as the Committee in its discretion shall deem relevant.
Subject to the provisions of the Plan, the Committee shall also have complete
authority to interpret the Plan, to prescribe, amend and rescind rules and
regulations relating to it, to determine the terms and provisions of the
respective Option Agreements or awards (which need not be identical), and to
make all other determinations necessary or advisable for the administration of
the Plan. The Committee's determinations on the matters referred to in this
Section 5 shall be conclusive.

6.   Eligibility. An Option or award may be granted only to an employee,
     -----------
director, or consultant of one or more of the Company and its subsidiaries.  A
Director of one or more of the Company and its subsidiaries who is not also an
employee of one or more of the Company and its subsidiaries shall not be
eligible to receive an Incentive Option.  Any person who, within the meaning of
Section 422(b)(6) of the Code, is deemed to own stock possessing more than 10%
of the total combined voting power of all classes of stock of the Company

                                       3
<PAGE>

(or of its parent or subsidiary corporations) shall not be eligible to receive
an Option. In any given fiscal year, no Recipient may receive Options or awards
or both covering more than 500,000 shares of Stock (such number of shares to be
adjusted in accordance with Section 14).

7.   Time of Granting Options. The granting of an Option or an award shall take
     ------------------------
place at the time specified by the Committee.  Only if expressly so provided by
the Committee, shall the Grant Date be the date on which an Option Agreement or
Restricted Share award shall have been duly executed and delivered by the
Company and the Recipient.

8.   Option Price. The Option Price under each Incentive Option shall be not
     ------------
less than 100% of the Fair Market Value of Stock on the Grant Date; the Option
Price under each Nonstatutory Option shall not be so limited.

9.   Option Period. No Incentive Option may be exercised later than the tenth
     -------------
anniversary of the Grant Date. The period during which a Nonstatutory Option may
be exercised shall not be so limited.  An Option may become exercisable in such
installments, cumulative or non-cumulative, as the Committee may determine.  In
the case of an Option not otherwise immediately exercisable in full, the
Committee may accelerate the exercisability of such Option in whole or in part
at any time, provided the acceleration of the exercisability of any Incentive
Option would not cause the Option to fail to comply with the provisions of
Section 422 of the Code.

10.  Limit on Incentive Option Characterization.  No Incentive Option shall be
     ------------------------------------------
considered an Incentive Option to the extent pursuant to its terms it would
permit the Recipient to purchase for the first time in any Vesting Year more
than the number of shares of Stock calculated by dividing the current limit by
the Fair Market Value on the Grant Date.  The current limit for any Recipient
for any Vesting Year shall be $100,000 minus the aggregate Fair Market Value at
the date of grant of the number of shares of Stock available for purchase for
the first time in such Vesting Year under each other Incentive Option granted to
the Recipient under the Plan and each other incentive stock option granted to
the Recipient under any other incentive stock option plan of the Company (and
its parent and subsidiary corporations).

11.  Exercise of Option.  An Option may be exercised in accordance with its
     ------------------
terms by written notice of intent to exercise the Option, specifying the number
of shares with respect to which the Option is then being exercised.  The notice
shall be accompanied by (a) full payment for such shares in the form of check or
bank draft payable to the order of the Company, or (b) certificates representing
shares of the Stock with a current Market Value equal to the Option Price of the
shares to be purchased, or (c) irrevocable instructions to a brokerage firm to
sell a sufficient number of the Option Shares to generate the full exercise
price plus all applicable withholding taxes and to pay over to the Company such
proceeds of sale..  Within 20 days thereafter, the Company shall deliver or
cause to be delivered to the Recipient evidence of ownership of the number of
shares then being purchased.  Such shares shall be fully paid and

                                       4
<PAGE>

nonassessable. If any law or applicable regulation of the Securities and
Exchange Commission or other public regulatory authority shall require the
Company or the Recipient to register or qualify under the Securities Act of
1933, as amended, any similar federal statute then in force or any state law
regulating the sale of securities, any Option Shares with respect to which
notice of intent to exercise shall have been delivered to the Company or to take
any other action in connection with such shares, the delivery of the certificate
or certificates for such shares shall be postponed until completion of the
necessary action, which the Company shall take in good faith and without delay.
All such action shall be taken by the Company at its own expense.

12.  Termination of Employment. In the event that the Recipient's employment or
     -------------------------
association with the Company is terminated, whether voluntarily or by reason of
dismissal or retirement, the Option, to the extent exercisable at the date of
termination, may be exercised by the Recipient within three months after he or
she ceases to be an employee, director or consultant.  In the event that the
Recipient's employment or association with the Company terminates as a result of
the death or disability of the Recipient, the Option may be fully exercised by
the Recipient or, in the event of the death of the Recipient by the person to
whom the option is transferred by will or the applicable laws of descent and
distribution, at any time within two years after the date of termination, unless
terminated earlier by its terms.  Military or sick leave shall not be deemed a
termination of employment provided that it does not exceed the longer of 90 days
or the period during which the absent employee's reemployment rights are
guaranteed by statute or by contract.  In the event that the Recipient's
employment or association with the Company terminates as a result of the death
or disability of the Recipient, the exercisability of any Option not otherwise
immediately exercisable in full held by such Recipient shall be accelerated and
such Options shall be fully exercisable as of the date of termination.

13.  Transferability of Options. Options shall not be transferable, otherwise
     --------------------------
than by will or the laws of descent and distribution, and may be exercised
during the life of the Recipient only by the Recipient.

14.  Adjustment of Number of Option Shares. In the event of any change in
     -------------------------------------
corporate capitalization, such as a stock split or a corporate transaction, such
as any merger, consolidation, separation, including a spin-off, or other
distribution of stock or property of the Company, any reorganization (whether or
not such reorganization comes within the definition of such term in Section 368
of the Code) or any partial or complete liquidation of the Company, the
Committee or Board may make such substitution or adjustments in the aggregate
number and kind of shares reserved for issuance under the Plan, in the number,
kind and Option Price of shares subject to outstanding Options, and/or such
other equitable substitution or adjustments as it may determine to be
appropriate in its sole discretion; provided, however, that the number of shares
subject to any Option shall always be a whole number.

                                       5
<PAGE>

15.  Restricted Shares. Each Restricted Share award shall be evidenced by a
     -----------------
Restricted Share award agreement that shall specify the number of Restricted
Shares awarded and such other provisions as the Board or Committee shall
determine.  The Restricted Shares may not be sold, transferred, pledged,
assigned, or otherwise alienated or hypothecated until satisfaction of the
conditions as specified by the Board or Committee and set forth in the
Restricted Share award agreement.  All rights with respect to Restricted Shares
granted to a Recipient under the Plan shall be available during his or her
lifetime only to the Recipient.  Recipients holding Restricted Shares may
exercise full voting rights with respect to those Restricted Shares.  Recipients
holding Restricted Shares will receive such cash dividends paid with respect to
the Restricted Shares as may be declared while they are so held.  Without
limiting the generality of the preceding sentence, if the grant or vesting of
Restricted Shares granted to a Recipient is designed to comply with the
requirements of the performance-based exception under Section 162(m) of the
Code, the Board or Committee may apply any restrictions it deems appropriate to
the payment of dividends declared with respect to such Restricted Shares, such
that the dividends and/or the Restricted Shares maintain eligibility for the
performance-based exception.

16.  Transferability. The Recipient agrees that he or she will not transfer any
     ---------------
of the Option Shares or Restricted Shares unless (i) such shares are registered
under the provisions of the Securities Act of 1933, as amended, or (ii) at the
request of the Company, the transferee represents, in form satisfactory to
counsel for the Company, that he or she will not transfer, sell or otherwise
dispose of the Option Shares at any time purchased by him or her in a manner
which would violate the Securities Act of 1933, as amended (the "Act"), and the
regulations of the Securities and Exchange Commission thereunder.  The Recipient
agrees that the Company may, at its discretion, make a notation on any
certificates issued upon exercise of any portion of the Option to the effect
that such certificate may not be transferred except after receipt by the Company
of an opinion of counsel satisfactory to it to the effect that such transfer
will not violate the Act and the regulations thereunder, and may issue "stop
transfer" instructions to its transfer agent, if any, and make a "stop transfer"
notation on its books as appropriate.

17.  Change of Control.
     -----------------

     (a) Vesting of Options.  In the event of a Change of Control, any Options
         -------------------
outstanding as of the date such Change of Control is determined to have
occurred, and which are not then exercisable and vested, shall become fully
exercisable and vested to the full extent of the original grant.

     (b) Elimination of Restrictions.  In the event of a Change of Control, all
         ----------------------------
restrictions with respect to all Restricted Shares outstanding as of the date
such Change of Control is determined to have occurred shall be eliminated.

     (c) Change of Control Cash-Out.  During the 60-day period from and after a
         --------------------------
Change of Control (the "Exercise Period"), unless the Committee shall

                                       6
<PAGE>

determine otherwise at the time of grant of an Option, each Recipient who is an
employee or consultant of one or more of the Company and its subsidiaries shall
have the right, whether or not the Option is fully exercisable and in lieu of
the payment of the Option Price for the shares of Stock being purchased under
the Option and by giving notice to the Company, to elect (within the Exercise
Period) to surrender all or part of the Option to the Company and to receive
cash, within 30 days of such notice, in an amount equal to the amount by which
the Change of Control Price per share of Stock on the date of such election
shall exceed the Option Price per share of Stock under the Option (the "Spread")
multiplied by the number of shares of Stock as to which the right granted under
this Section 17 shall have been exercised. Notwithstanding the foregoing, if any
right granted pursuant to this Section 17 would make a Change of Control
transaction ineligible for pooling-of-interests accounting under APB No. 16 that
but for the nature of such grant would otherwise be eligible for such accounting
treatment, the Committee shall have the ability to substitute for the cash
payable pursuant to such right Stock or other securities with a fair market
value equal to the cash that would otherwise be payable hereunder.

     (d) Definition of Change of Control Price. "Change of Control Price" means
         -------------------------------------
the higher of (i) the highest reported sales price, regular way, of a share of
Stock in any transaction reported on the New York Stock Exchange Composite Tape
or other national exchange on which such shares are listed or on NASDAQ National
Market during the 60-day period prior to and including the date of a Change of
Control or (ii) if the Change of Control is the result of a tender or exchange
offer or a Corporate Transaction, the highest price per share of Stock paid in
such tender or exchange offer or Corporate Transaction; provided, however, that
in the case of Incentive Options, the Change of Control Price shall be in all
cases the fair market value of the Stock on the date the right under Section
16(b) associated with such Incentive Option is exercised.  To the extent that
the consideration paid in any such transaction described above consists all or
in part of securities or other noncash consideration, the value of such
securities or other noncash consideration shall be determined in the sole
discretion of the Board.

     (e) Definition of Change of Control. For purposes of the Plan, a "Change of
         ---------- --------------------
Control" shall mean:

         (i) The acquisition by any individual, entity or group (within the
meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934,
as amended (the "Exchange Act")) (a "Person") of beneficial ownership (within
the meaning of Rule 13d-3 promulgated under the Exchange Act) of 20% or more of
either (a) the then outstanding shares of Stock (the "Outstanding Company Common
Stock") or (b) the combined voting power of the then outstanding voting
securities of the Company entitled to vote generally in the election of
directors (the "Outstanding Company Voting Securities"); provided, however, that
for purposes of this subsection (i), the following acquisitions shall not
constitute a Change of Control: (A) any acquisition directly from the Company,
(B) any acquisition by the Company, (C) any acquisition by any

                                       7
<PAGE>

employee benefit plan (or related trust) sponsored or maintained by the Company
or any corporation controlled by the Company or (d) any acquisition pursuant to
a transaction which complies with clauses (A), (B) and (C) of subsection (iii)
of this Section 16; or

          (ii)   Individuals who, as of June 8, 1999, constitute the Board (the
"Incumbent Board") cease for any reason to constitute at least a majority of the
Board; provided, however, that any individual becoming a director subsequent to
June 8, 1999 whose election, or nomination for election by the Company's
stockholders, was approved by a vote of at least a majority of the directors
then comprising the Incumbent Board shall be considered as though such
individual were a member of the Incumbent Board, but excluding, for this
purpose, any such individual whose initial assumption of office occurs as a
result of an actual or threatened election contest with respect to the election
or removal of directors or other actual or threatened solicitation of proxies or
consents by or on behalf of a Person other than the Board; or

          (iii)  Consummation of a reorganization, merger or consolidation or
sale or other disposition of all or substantially all of the assets of the
Company or the acquisition of assets of another entity (a "Corporate
Transaction"), in each case, unless, following such Corporate Transaction, (A)
all or substantially all of the individuals and entities who were the beneficial
owners, respectively, of the Outstanding Company Common Stock and Outstanding
Company Voting Securities immediately prior to such Corporate Transaction
beneficially own, directly or indirectly, more than 60% of, respectively, the
then outstanding shares of common stock and the combined voting power of the
then outstanding voting securities entitled to vote generally in the election of
directors, as the case may be, of the corporation resulting from such Corporate
Transaction (including, without limitation, a corporation which as a result of
such transaction owns the Company or all or substantially all of the Company's
assets either directly or through one or more subsidiaries) in substantially the
same proportions as their immediately prior to such Corporate Transaction of the
Outstanding Company Common Stock and Outstanding Company Voting Securities, as
the case may be, (B) no Person (excluding any employee benefit plan (or related
trust) of the Company or such corporation resulting from such Corporate
Transaction) beneficially owns, directly or indirectly, 20% or more of,
respectively, the then outstanding shares of common stock of the corporation
resulting from such Corporate Transaction or the combined voting power of the
then outstanding voting of such corporation except to the extent that such
ownership existed prior to the Corporate Transaction and (C) at least a majority
of the members of the board of directors of the corporation resulting from such
Corporate Transaction were members of the Incumbent Board at the time of the
execution of the initial agreement, or of the action of the Board, providing for
such Corporate Transaction; or

          (iv)   Approval by the stockholders of the Company of a complete
liquidation or dissolution of the Company.

                                       8
<PAGE>

18.  Reservation of Stock. The Company shall at all times reserve and keep
     ----------- --------
available such number of shares of the Stock as will be sufficient to satisfy
the requirements of this Plan and shall pay all fees and expenses necessarily
incurred by the Company in connection therewith.

19.  Limitation of Rights in the Option Shares. A Recipient shall not be deemed
     -----------------------------------------
for any purpose to be a stockholder of the Company with respect to any of the
Option Shares except to the extent that the Option shall have been exercised
with respect thereto and, in addition, a certificate shall have been issued
therefore and delivered to the Recipient.  Any Stock issued pursuant to the
Option shall be subject to all restrictions upon the transfer thereof which may
be now or hereafter imposed by the Articles of Organization or the By-laws of
the Company.

20.  Termination and Amendment of the Plan. The Board may at any time terminate
     -------------------------------------
the Plan or make such modifications of the Plan as it shall deem advisable;
provided that no modification shall be effective to increase the number of
- --------
shares of Stock subject to the Plan or change the number or classification of
employees eligible to receive Options until such modification is approved by the
holders of a majority of the Company's common stock represented in person or by
proxy and voting at a meeting.  No termination or amendment of the Plan may,
without the consent of the Recipient to whom any Option shall theretofore have
been granted, adversely affect the rights of such Recipient under such Option.

21.  Notices.  Any communication or notice required or permitted to be given
     -------
under the Plan shall be in writing, and mailed by registered or certified mail
or delivered in hand, if to the Company, to its Treasurer at University Avenue,
Westwood, Massachusetts 02090 and, if to the Recipient, to the address as the
Recipient shall last have furnished to the communicating party.

22.  Withholding;  Notice of Disposition of Stock Prior to Expiration of
     -------------------------------------------------------------------
Specified Holding Period.
- ------------------------

     (a) Whenever shares are to be issued in satisfaction of an Option granted
hereunder, the Company shall have the right to require the Recipient to remit to
the Company an amount sufficient to satisfy federal, state, local or other
withholding tax requirements if and to the extent required by law (whether so
required to secure for the Company an otherwise available tax deduction or
otherwise) prior to the delivery of any certificate or certificates for such
shares.

     (b) The Company may require as a condition to the issuance of shares
covered by an Incentive Option that the party exercising such Option give a
written representation to the Company which is satisfactory in form and
substance to its counsel and upon which the Company may reasonably rely, that he
or she will report to the Company any disposition of such shares prior to the
expiration of the holding periods specified by Section 422(a)(1) of the Code.
If and to the extent that the realization of income in such a disposition
imposes upon the Company federal, state, local or other withholding tax

                                       9
<PAGE>

requirements, or any other available tax deduction, the Company shall have the
right to require that the recipient remit to the Company an amount sufficient to
satisfy those requirements; and the Company may require as a condition to the
issuance of shares covered by an Incentive Option that the party exercising such
option give a satisfactory written representation promising to make such a
remittance.
