ITEM 1.  BUSINESS
 
OVERVIEW
 
     LTX Corporation ("LTX" or the "Company") designs, manufactures and markets
automatic test equipment for the semiconductor industry that is used to test
digital, linear and mixed signal (a combination of digital and linear)
integrated circuits ("ICs") and discrete semiconductor components. The Company
currently offers three lines of test systems: digital test systems, which test
digital ICs, including microprocessors and microcontrollers; linear/mixed signal
test systems, which test a wide range of linear and mixed signal ICs; and
discrete component test systems, which test small signal and high power
semiconductor components. In fiscal 1998, the Company will introduce LTX Fusion,
a single platform test system designed to test system-on-a-chip devices. The
Company also sells service and applications support 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 both manufacturers and users of digital,
linear and mixed signal ICs and discrete semiconductor components.
 
INDUSTRY BACKGROUND
 
     All semiconductor manufacturers use semiconductor test equipment ("STE") in
the design and manufacture of ICs. During design, STE is used for design
verification, characterization, qualification and failure analysis of ICs.
During manufacture, STE is used during wafer probing to select usable ICs and
after packaging to classify ICs by performance characteristics and to assure
conformance with quality standards. Typically, all ICs are tested two or more
times during the manufacturing process. In addition, certain large electronic
equipment manufacturers employ STE for incoming inspection and for further
classification of ICs.
 
     Demand for STE is driven by overall business expansion in the semiconductor
industry and advances in semiconductor technology. When demand for
semiconductors increases, semiconductor manufacturers will often purchase STE to
meet their growing capacity requirements. Advances in semiconductor technology
have allowed for increasingly complex semiconductor devices with improved
performance, lower cost and greater reliability than earlier generations of
devices. As a result, the use of semiconductors has proliferated across many
industries, particularly in applications for the computer, communications,
automotive and consumer electronics industries. In turn, semiconductor
manufacturers are demanding STE that is faster, more versatile, more accurate,
more productive and easier to program and maintain.
 
     Prices of STE systems generally increase as their capabilities increase.
The acquisition of STE represents a significant investment on the part of the
Company's customers, who typically consider both the capital and long term
operating costs of the test system in the acquisition process. Factors that can
vary from one test system to another, and thereby affect the total cost of
testing, include:
 
     Speed.  A test system that offers faster test times or that is able to test
more than one device at a time is able to test a greater number of devices over
its product life, thus increasing the system's efficiency and reducing the
customer's cost of testing.
 
     Accuracy.  Superior accuracy improves the yield of the semiconductor
production process because it reduces the number of good devices that are
improperly rejected and permits the selection of a higher number of premium
devices.
 
     Efficiency.  Greater efficiency in test program preparation, loading and
debugging leads to faster time to market for newly-designed semiconductors.
 
     Software.  Test system operating software which is easier to use and more
powerful reduces the amount of engineering resources needed to develop test
programs and operate test systems.
 
     Reliability.  A test system that operates with minimal downtime allows the
customer's production and engineering work to proceed without frequent
intervention and provides more cost-effective operation.
 
                                        1
<PAGE>   4
 
     System Architecture.  Test system architecture that is modular extends the
product life of a test system because the system can be adapted to meet the
customer's new requirements while largely retaining compatibility with existing
test programs.
 
     Customer Support.  Customer specific applications programs, worldwide
service and customer training contribute to the efficient use of STE and
minimize the customer's cost of testing.
 
COMPANY STRATEGY
 
     The key components of the Company's strategy are as follows:
 
  Develop Single Test Platform for Testing Systems-on-a-Chip
 
     In fiscal 1997, the Company reorganized and integrated its linear/mixed
signal and digital engineering organizations to develop a single platform
systems-on-a-chip test system, LTX Fusion. By focusing its resources on a
single, shared technology product roadmap, the Company believes it will be able
to deliver the best mixed signal, digital and embedded memory test performance
for testing system-on-a-chip devices. The LTX Fusion test system is being
developed to enable complete functional testing of the embedded mixed signal,
digital and memory components of a system-on-a-chip device, as well as to
perform system-level testing related to the devices' end-use application. The
Company believes that superior test performance at the sub-component level,
without compromising functionality, is necessary to meet the requirements of the
emerging systems-on-a-chip market.
 
  Provide Application Specific Solutions
 
     The Company is committed to providing complete test solutions to its
customers by having a substantial group of engineers strategically located at
customer support centers throughout the world. By actively participating in the
application of its test systems, the Company is able to learn more about
requirements for new devices and to improve the design of future test systems.
LTX also believes that its participation in the application of its test systems
enables its customers to get devices to market more rapidly and builds stronger
ties with these customers.
 
  Leverage Worldwide Presence
 
     The semiconductor business is a worldwide industry, with well-established
manufacturers in the United States, Europe and the Far East. The Company has
nine offices in the United States, and in Europe maintains sales and support
offices in the United Kingdom, France, Italy and Germany. In recent years, an
increasing portion of semiconductor test and assembly operations have been
conducted in the Pacific Rim by manufacturers based in the United States and
Europe, as well as by local manufacturers. LTX has established sales and support
offices in Korea, Taiwan and Singapore to focus on the specific needs of the
markets within the Pacific Rim. In addition, through a majority-owned
subsidiary, the Company provides sales and support services at three locations
in Japan. The Company believes that this network of sales and support centers
improves its ability to sell and support its products to the world's major
semiconductor manufacturers.
 
  Emphasize Quality and Reliability
 
     The Company's quality program is designed to continually improve all of its
processes and increase the satisfaction of its customers. The Company believes
that this program will lead to: more efficient and timely performance in
engineering projects; improvement in manufacturing costs through the reduction
of defective products and manufacturing cycle time; better on-time delivery
performance; and greater reliability of its test systems. During fiscal 1997,
the Company expanded its ISO 9001 certification and its worldwide design,
manufacturing and service functions are now ISO 9001 certified.

PRODUCTS AND MARKETS
 
  Product Overview
 
     The Company currently sells products in three broad product categories:
 
     - Systems that are used to test linear and mixed signal devices, which
       include the Synchro Series and Ninety;
 
     - Systems that are used to test digital devices, which include the
       Delta/STE and Master Series, and enVision test development software; and
 
     - Discrete component test systems, marketed as the iPTest product line.
 
     The Company's test systems are used by semiconductor manufacturers for
design verification, characterization, qualification and failure analysis of
ICs. In addition, certain large electronic equipment manufacturers use the
Company's test systems for incoming inspection and for further classification of
ICs. All of the Company's test systems are comprised of multiple
computer-controlled instruments which send signals to a device under test and
measure the responses of that device to classify the device by performance
characteristics and to ensure conformance with quality standards. The Company's
test system instrumentation is controlled by operating system software which is
developed by the Company. The Company also develops and sells test programs for
specific devices and offers software packages for use by semiconductor
manufacturers for test simulation in engineering design and test program
generation, data collection and statistical analysis in manufacturing.
 
  Linear and Mixed Signal ICs
 
     Linear ICs are used in almost every electronic application. Physical
occurrences, such as sound, images, temperature, pressure, speed, acceleration,
position and rotation, consist of continuously varying information. Linear ICs
are used to amplify, filter and shape this information. Mixed signal ICs convert
the signals from linear ICs into digital signals that can be processed by a
computer. Mixed signal devices also convert processed digital information into a
linear form to control physical phenomena or to improve sound and images.
 
     Linear and mixed signal ICs are widely used in automobiles, appliances,
personal computers, telephone systems, personal communication products, such as
cellular telephones and pagers, and home entertainment products. The complexity
and density of these ICs have increased rapidly over the past several years, as
the demand for portable, battery-operated products has required IC manufacturers
to integrate more functions on each chip and reduce size and power consumption.
These technological advances have resulted in increased demand for higher
performance linear/mixed signal test systems.
 
  Digital ICs
 
     Digital ICs include microprocessors, microcontrollers, programmable DSPs
(digital signal processing), microperipherals and logic/ASIC (application
specific IC) devices. These ICs are used for computing, controlling and
calculating functions, and are at the heart of most electronic products. The
most well known of these devices is the microprocessor, which is the enabler of
personal computer technology. Microcontrollers, however, are much more broadly
used in automobiles, appliances, home entertainment products and many other
electronic products which utilize electronic control functions. Microprocessors
can cost hundreds or even thousands of dollars, while microcontrollers typically
cost tens of dollars. However, testing of microcontrollers can be as complex as
microprocessors and requires high performance test systems.
 
  System-on-a-Chip ICs
 
     System-on-a-chip ICs incorporate VLSI logic cores, embedded memory and
mixed signal interfaces on a single device and, therefore, can be used as a
product's entire electronic system. System-on-a-chip ICs will enable the
graphics, display, multimedia capabilities and communications functions of the
next generation of electronics products. These products include advanced pagers,
digital cameras, and cellular phones; digital
 
                                        3

high-definition TVs and home satellite set-top boxes; mobile Internet terminals
and modems; personal digital assistants with real-time audio and video; active
suspension and automotive collision avoidance systems; powerful graphics
accelerators; and digital motor controls. The need to test system-on-a-chip ICs
at both the subcomponent level and the system level will require test equipment
with high performance logic, memory and mixed signal capabilities.
 
LINEAR/MIXED SIGNAL PRODUCTS
 
     LTX offers two product lines for testing linear/mixed signal ICs, the
Synchro Series and Ninety.
 
  Synchro Series
 
     Synchro test systems are designed for high throughput testing of linear
devices and for testing mixed signal devices that require high digital pattern
rates and high digital pin counts along with analog signal generation and
measurement requirements. The Synchro features DSP (digital signal
processing) -- per-pin architecture which allows for concurrent control of both
linear and digital resources at each pin of the IC under test. This design
permits the generation of test signals and measurements on many device pins at
the same time, producing faster test times on high pin count ICs. The Synchro
systems are modular in design which enables customers to add new options to
their systems in the future. This allows customers to increase the capability of
their Synchro system to meet their new test requirements. Since its
introduction, the Company has significantly upgraded the performance and
capabilities of the Synchro through the introduction of new hardware and
software.
 
     The Synchro Series includes the Synchro II, Synchro Plus and Synchro
ProductionPAC test systems:
 
     Synchro II.  The configuration of the Synchro II test system is flexible.
This permits LTX customers to choose from a wide array of options to meet the
test requirements of a broad range of linear/mixed signal devices.
 
     Synchro Plus.  The Synchro Plus test system is configured with SuperSpeed
Data Pins which can test mixed signal devices at data rates of up to 400 MHz.
The Synchro Plus system addresses the test requirements of new, high speed
devices used in applications such as disk drives for personal computers and
advanced ATM(Asynchronous Transfer Mode) interface boards used to support the
development of the information superhighway.
 
  Synchro ProductionPAC.
 
     The Synchro ProductionPAC test systems are lower cost, smaller footprint,
specifically focused configurations that address the production requirements of
high volume, low cost mixed signal devices. The RFPAC system is configured to
test devices used in the rapidly expanding wireless communications market. The
PowerPAC addresses "smart" power devices that are being increasingly used in
automobiles and consumer electronics. The TelePAC addresses commodity ICs used
in telecommunications. The ConverterPAC is focused on devices used in multimedia
applications.
 
     All Synchro Series test systems are fully compatible in hardware, software
and specification.
 
  Ninety
 
     The Ninety system is an improved version of the LTX77, the Company's first
linear/mixed signal test system introduced in 1977. Although the Synchro has
largely superseded the Ninety, the Company has continued to manufacture the
Ninety for customers who are already using the Ninety or LTX77 systems and
desire to expand capacity. Many of the Ninety or LTX77 systems the Company has
previously sold are currently still in use. In the past, the Company has
upgraded the performance and capabilities of the Ninety system through the
introduction of new hardware and software.
 
                                        4
<PAGE>   7
 
  Software Tools
 
     The Company offers two software options to facilitate the development of
test solutions off-line, called Device Tool and Synchro Models Toolbox. These
software tools work in conjunction with IC design and simulation software
allowing test solutions to be designed and debugged with a model of the IC.
Device Tool and the Synchro Models Toolbox allow the development of test
solutions concurrent with the design of the IC, reducing customers time to
market for the IC.
 
DIGITAL PRODUCTS
 
     LTX offers two product lines for testing digital ICs, the Delta/STE and the
Master Series. The Delta/STE and Master Series are based on a resource-per-pin
architecture which allows for a complete set of the test system's key features
(timing generators, waveform formatting and pattern memory) for each pin channel
of the test system. The Company believes that this architecture provides for
faster, simpler characterization and engineering debugging of new ICs, better
system timing accuracy, and simplified interfacing with computer-aided design
systems. The Company's enVision test development software is sold with both the
Delta/STE and the Master Series.
 
  Delta/STE
 
     The Delta/STE, introduced in fiscal 1996, incorporates mixed signal
technology with digital technology to address the test requirements of a new
generation of devices with high performance analog signal interfaces to complex
digital functions. These new devices are enabling the development of powerful,
yet low cost consumer electronic products in areas such as multimedia and
portable communications. The Delta/STE operates with the Company's enVision
graphical software environment providing customers with compatibility among
these systems.
 
     In fiscal 1993, the Company entered into a development, manufacturing and
marketing agreement with Ando, a Japanese STE manufacturer and majority-owned
subsidiary of NEC, relating to the Company's Delta resource-per-pin digital test
system. Under the agreement, the Company granted Ando exclusive rights in Japan
to manufacture digital test systems based on the Company's Delta
resource-per-pin digital technology. The Company retained exclusive
manufacturing rights outside of Japan. Ando has the exclusive right in Japan to
sell its test systems based upon the Delta resource-per-pin digital technology
and the Company has exclusive marketing rights to these test systems for the
rest of the world, with certain exceptions in each case.
 
  Master Series
 
     The Master Series product line includes the Deltamaster and Micromaster
test systems, which are enhanced versions of the Company's original digital test
system. The Deltamaster is capable of testing up to 256 pins at data rates of up
to 80 MHz. The Micromaster is a lower-priced system that can test up to 256 pins
at data rates of up to 40 MHz. The Micromaster is device interface and software
compatible with the Deltamaster. Although the Delta/STE has essentially replaced
the Master Series, the Company has continued to sell the Master Series test
systems to customers who are already using these systems and desire to expand
capacity.
 
  enVision
 
     enVision, the Company's object-oriented programming software is designed
for use on all of its digital test systems. In earlier generation software
languages, programming commands made direct reference to the hardware of the
test system, which required the user to have a detailed knowledge of the
system's hardware. In contrast, this detailed knowledge is not required when
using enVision, thereby allowing the programmer to focus attention on refining
the test program for the specific IC under test. Thus, the Company has designed
enVision to be more device oriented than tester oriented. enVision permits a
user to test multiple devices at the same time, significantly improving the
throughput of the Company's digital test systems. enVision is an integral
feature of the Delta/STE and can be purchased by customers of the Master Series
product line.

DISCRETE PRODUCTS
 
     The Company's iPTest systems are used to test discrete components, such as
power transistors, as well as arrays of these components. The Company expects
that arrays of discrete components, such as multi-device modules, will replace
transistors in electric motor control and will permit a wider use of
semiconductors in extremely high power applications, such as air conditioners,
domestic appliances, electric locomotives and automobiles. These arrays of
discrete components are mostly constructed from IGBT (insulated gate bipolar
transistor) technology and include devices such as intelligent power modules and
power MOSFETS. In fiscal 1996, the Company introduced the iPTest PowerTrak
system to address intelligent power modules (IPM) as well as the iPTest high
speed parallel test MosTrak system to address discrete power MOSFETS and IGBT
transistors.
 
     In fiscal 1995, the Company entered into a development, manufacturing and
marketing agreement with Asia Electronics, a Japanese STE manufacturer which is
50% owned by Toshiba, relating to a discrete component test system for testing
integrated power modules. As part of the agreement, Asia Electronics paid the
Company $1.5 million and may make royalty payments in the future based on sales
of this system. The Company granted Asia Electronics exclusive manufacturing
rights in Japan and the right to sell these systems to its customers in Japan.
 
SERVICE
 
     The Company considers service to be an important aspect of its business.
The Company's worldwide service organization is capable of performing
installations and all necessary maintenance of test systems sold by the Company,
including routine servicing of components manufactured by third parties. The
Company provides a one-year parts and three-month labor warranty on test systems
or options designed and manufactured by the Company, and a three-month labor
warranty on components that have been purchased from other manufacturers and
incorporated into the Company's test systems. The Company also provides training
on the maintenance and operation of test systems sold to its customers.
 
     The Company offers a wide range of service contracts which gives its
customers flexibility to select the maintenance program best suited to their
needs. Customers may purchase service contracts which extend maintenance beyond
the initial warranty provided by the Company with the sale of its test systems.
Many customers enter into annual or multiple-year service contracts over the
life of the equipment. The pricing of contracts is based upon the level of
service provided to the customer and the time period of the service contract. As
the installed base of LTX test systems has grown, service revenues have been
increasing on an annual basis. The Company believes that service revenues should
be less affected by the cyclicality of the semiconductor industry than sales of
test equipment. The Company maintains 22 service centers around the world.
 
SALES AND DISTRIBUTION
 
     The Company sells its products primarily through its worldwide sales
organization. In Japan, the Company sells, services and supports its products
through its joint venture with SMI, except that Ando has the right to
manufacture and sell digital test systems, based on the Delta resource-per-pin
digital technology, to certain customers in Japan. The Company will share with
its SMI joint venture specified portions of the royalties to be paid by Ando on
any sales of its digital test systems. Asia Electronics also has the right to
sell the Company's iPTest systems to certain customers in Japan. The Company
uses a small number of independent sales representatives in certain other
regions of the world.
 
     Sales to customers outside the United States are subject to risks,
including the imposition of governmental controls, the need to comply with a
wide variety of foreign and United States export laws, political and economic
instability, trade restrictions, changes in tariffs and taxes, longer payment
cycles typically associated with international sales, and the greater difficulty
of administering business overseas as well as general economic conditions. Sales
by the Company to customers outside the United States are primarily denominated
in United States dollars. Sales by the Company to customers outside North
America were 67%, 64% and 66% of total sales of the Company in fiscal 1997, 1996
and 1995, respectively.

CUSTOMERS
 
     The Company's customers include many of the world's leading semiconductor
manufacturers. The Company's major customers in fiscal 1997 included:
 
<TABLE>
               <S>                              <C>
               Intel                            Samsung
               Hitachi                          SGS Thomson
               National Semiconductor           Siemens
               Philips                          STATS
               Rockwell                         Texas Instruments
</TABLE>
 
     Sales to these major customers accounted for approximately 55% of net sales
in fiscal 1997. Sales to Intel and National Semiconductor accounted for 13% and
12% of net sales in fiscal 1997, respectively. Sales to Philips accounted for
17% of net sales in fiscal 1995. No single customer accounted for 10% or more of
net sales in fiscal 1996.
 
ENGINEERING AND PRODUCT DEVELOPMENT
 
     The STE market is characterized by rapid technological change and new
product introductions, as well as advancing industry standards. The Company's
ability to remain competitive will depend upon its ability to successfully
enhance existing test systems and develop new generations of test systems and to
introduce these new products on a timely and cost-effective basis. Accordingly,
the Company devotes a significant portion of its personnel and financial
resources to engineering and product development programs and seeks to maintain
close relationships with its customers in order to be responsive to their
product needs. The Company's expenditures for engineering and product
development were $23.4 million, $22.9 million and $19.8 million during fiscal
1997, 1996 and 1995, respectively.
 
     The Company's engineering strategy is to develop its test systems in an
evolutionary manner so that they may be progressively upgraded. This approach
preserves its customers' substantial investments in test programs, and, in
general, maintains market acceptance for the Company's test systems. In order to
implement this strategy, the Company works closely with its customers to define
new product features and to identify emerging applications for its products.
 
MANUFACTURING AND SUPPLY
 
     LTX's principal manufacturing operations consist of component parts
assembly, final assembly and testing at its manufacturing facilities in
Westwood, Massachusetts and San Jose, California. In addition, the Company
outsources certain subassemblies to contract manufacturers. The Company uses
standard components and prefabricated parts manufactured to the Company's
specifications. Most of the components for the Company's products are available
from a number of different suppliers; however, certain components are purchased
from a single supplier. Although LTX believes that all single-source components
currently are available in adequate amounts, there can be no assurance that
shortages will not develop in the future. Any disruption or termination of
supply of certain single-source components could have an adverse effect on the
Company's business and results of operations.
 
COMPETITION
 
     The STE industry is highly competitive, with many other domestic and
foreign companies participating in the markets for each of the Company's
products. The Company's major competitors in the market for digital test systems
are Schlumberger Limited, Teradyne, Inc. and Credence Systems Corporation,
except in Japan where the Company's major competitor is Advantest Corporation
(an affiliate of Fujitsu Limited). The Company's principal competitor for
linear/mixed signal test systems is Teradyne, Inc. The Company's principal
competitor for discrete component test systems is Tesec, Ltd. Most of the
Company's major competitors are also suppliers of other types of automatic test
equipment and have significantly greater financial and other resources than the
Company.
 
                                        7
<PAGE>   10
 
     The Company principally competes on the basis of performance, cost of test,
reliability, customer service, applications support, price and ability to
deliver its products on a timely basis. Although the Company believes that it
competes favorably with respect to each of these factors, new product
introductions by the Company's competitors could cause a decline in sales or
loss of market acceptance of the Company's existing products or future products.
In addition, increased competitive pressure could lead to intensified
price-based competition, resulting in lower prices and adversely affecting the
Company's business and results of operations.
 
BACKLOG
 
     At July 31, 1997, the Company's backlog of unfilled orders for all products
and services was $65.1 million, compared with $65.5 million at July 31, 1996.
The Company expects to deliver approximately 90% of its July 31, 1997 backlog in
fiscal 1998. While backlog is calculated on the basis of firm orders, no
assurance can be given that customers will purchase the equipment subject to
such orders. As a result, the Company's backlog at a particular date is not
necessarily indicative of actual sales for any succeeding period.
 
PROPRIETARY RIGHTS
 
     The development of the Company's products is largely based on proprietary
information. The Company relies upon a combination of contract provisions,
copyright, trademark and trade secret laws to protect its proprietary rights in
products. It also has a policy of seeking patents on technology considered of
particular strategic importance. Although the Company believes that the
copyrights, trademarks and patents it owns are of value, the Company believes
that they will not determine the Company's success, which depends principally
upon its engineering, manufacturing, marketing and service skills. However, the
Company intends to protect its rights when, in its view, these rights are
infringed upon.
 
     The Company licenses some software programs from third party developers and
incorporates them in the Company's products. Generally, such agreements grant to
the Company non-exclusive licenses with respect to the subject program and
terminate only upon a material breach by the Company. The Company believes that
such licenses are generally available on commercial terms from a number of
licensors.
 
     The use of patents to protect hardware and software has increased in the
STE industry. The Company has at times been notified of claims that it may be
infringing patents issued to others. Although there are no pending actions
against the Company regarding any patents, no assurance can be given that
infringement claims by third parties will not have a material adverse effect on
the Company's business and results of operations. As to any claims asserted
against the Company, the Company may seek or be required to obtain a license
under the third party's intellectual property rights. There can be no assurance,
however, that a license will be available under reasonable terms or at all. In
addition, the Company could decide to resort to litigation to challenge such
claims or a third party could resort to litigation to enforce such claims. Such
litigation could be expensive and time consuming and could materially adversely
affect the Company's business and results of operations.
 
EXECUTIVE OFFICERS OF THE COMPANY
 
     The executive officers of the Company, as of October 1, 1997, are as
follows:

EMPLOYEES
 
     At July 31, 1997, the Company had a total of 950 employees, including 248
in engineering and product development, 204 in service and customer support, 294
in manufacturing and 204 in sales, marketing and administration. Many of the
Company's employees are highly skilled, and the Company believes its future
success will depend in large part on its ability to attract and retain such
employees. None of the Company's employees are represented by a labor union, and
the Company has experienced no work stoppages.
 
ENVIRONMENTAL AFFAIRS
 
     The Company's manufacturing facilities are subject to numerous laws and
regulations designed to protect the environment. The Company does not anticipate
that compliance with these laws and regulations will have a material effect on
its capital expenditures, earnings or competitive position.
 
ITEM 2.  PROPERTIES
 
     All of the Company's facilities are leased. The Company maintains its
headquarters in Westwood, Massachusetts, where corporate administration, sales
and customer support and manufacturing and engineering for its mixed signal
products are located in a 167,000 square foot facility under a lease which
expires in 2007. In May 1995, the Company subleased to a third party a 208,000
square foot facility in Westwood, Massachusetts for a ten year term. The
Company's lease of this facility expires in 2010. Manufacturing and engineering
for the Company's digital products are located in a 70,000 square foot facility
in San Jose, California. The Company's lease of this facility expires in 1999.
The Company has a five year option to extend this lease. The Company also leases
seven sales and customer support offices at various locations in the United
States totaling approximately 40,000 square feet.
 
     The Company's European headquarters is located in Woking, United Kingdom.
The Company also maintains sales and support offices at four other locations in
Europe. The manufacturing and engineering facilities for the Company's iPTest
systems are located in Guildford, United Kingdom. The Company also maintains
sales and support offices in six locations in the Far East. Office space leased
in Europe and the Far East totals approximately 100,000 square feet.
 
     The headquarters of LTX Co., Ltd., the Company's joint venture with SMI, is
located in Kawasaki, Japan. The joint venture also leases additional offices in
two other locations in Japan. Office space leased in Japan totals approximately
10,000 square feet.
 
     The Company believes that its existing facilities are adequate to meet its
current and foreseeable future requirements.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     In June 1996, the Company was notified by Korean semiconductor manufacturer
Daewoo that certain purchase agreements aggregating $50.1 million were not
properly authorized and would not be honored.
 
     The Company initiated litigation seeking to enforce those agreements in
June 1996. In September 1997, a federal district court judge in Boston,
Massachusetts determined that the court does not have jurisdiction in this
lawsuit. The Company is appealing the decision. These purchase agreements were
not included in the Company's backlog at July 31, 1997 or July 31, 1996.
 
     The Company has no other material pending legal proceedings other than
routine litigation relating to its business.

office of the Agent set forth in Section 10.1 hereof in immediately available
funds, such Bank's Commitment Percentage of each Loan. After Agent's receipt of
such funds and upon fulfillment of the applicable conditions set forth in
Section III hereof the Agent will credit the amount of such funds to the
Company's demand deposit account with the Agent.

          (c) Unless the Agent shall have received notice from a Bank prior to
the date of any Loan that such Bank will not make available to the Agent such
Bank's Commitment Percentage of such Loan, the Agent may assume that such Bank
has made such funds available to the Agent on the date of such Loan in
accordance with and as provided in this Section 2.2, and the Agent may, in
reliance upon such assumption, (but shall have no obligation to) make available
on such date a corresponding amount to the Company. If and to the extent any
Bank shall not have made its Commitment Percentage of any Loan available to the
Agent and the Agent shall have made available a corresponding amount to the
Company, such Bank agrees to pay to the Agent forthwith on demand, and the
Company agrees to repay to the Agent within three (3) Business Days after demand
(but only after demand for payment has first been made to such Bank and such
Bank has failed to make such payment), an amount equal to such corresponding
amount together with interest thereon for each day from the date the Agent shall
have made such amount available to the Company until the date such amount is
paid or repaid to the Agent, at an interest rate equal to the interest rate
applicable at the time to the Loans. If such Bank shall pay to the Agent such
corresponding amount, such amount so paid shall constitute such Bank's Loan for
purposes of this Agreement. If the Company makes a repayment required by the
foregoing provisions of this Section 2.2(c) and thereafter the applicable Bank
or Banks make the payments to the Agent required by this Section 2.2(c), the
Agent shall promptly refund the amount of the Company's payment.

          (d) The failure of any Bank to make any Loan shall not relieve any
other Bank of its obligation, if any, hereunder to make its Commitment
Percentage of such Loan on the date of such Loan, but no Bank shall be
responsible for the failure of any other Bank to make the Loan to be made by
such other Bank.

          (e) Subject to all the terms and conditions hereof, the Company may,
by delivering a notice (a "PRICING NOTICE") to the Agent received prior to 12:00
noon Boston time on the date two Business Days prior to the commencement of the
Interest Period selected in such Pricing Notice, elect to have all or a portion
of the outstanding Advances, as the Company may specify in such Pricing Notice,
accrue and bear daily interest during the Interest Period so selected at a per
annum rate equal to the Applicable LIBOR Rate for such Interest Period;
PROVIDED, HOWEVER, that any such election made with respect to the Advances
shall be in an


                                       10
<PAGE>   15

amount not less than $1,000,000 and increments of $500,000 thereafter and not
more than five (5) LIBOR Rate Loans shall be in effect at any time. Interest on
Loans bearing interest at the Applicable LIBOR Rate shall be paid for the
applicable Interest Period on the last day of such Interest Period and when such
Loan is due (whether at maturity, by reason of acceleration or otherwise). Each
Pricing Notice shall be substantially in the form of EXHIBIT C attached hereto
and shall specify: (i) the selection of a LIBOR Pricing Option or Alternative
Base Rate; (ii) the effective date and amount of Advances subject to such LIBOR
Pricing Option, subject to the limitations set forth herein; and (iii) the
duration of the applicable Interest Period, if any. Each Pricing Notice shall be
irrevocable. No election of a LIBOR Pricing Option shall become effective if,
prior to the commencement of any such LIBOR Interest Period, the Agent
determines that (a) the electing or granting of the LIBOR Pricing Option in
question would violate a Legal Requirement, (b) deposits in an amount comparable
to the principal amount of the Advances as to which such LIBOR Pricing Option
has been elected and which have a term corresponding to the proposed LIBOR
Interest Period are not readily available in the London inter-bank market or (c)
by reason of circumstances affecting the London inter-bank market, adequate and
reasonable methods do not exist for ascertaining the interest rate applicable to
such deposits for the proposed LIBOR Interest Period.

          (f) The Agent may fund any portion of the Advances subject to a LIBOR
Pricing Option out of any funds available to the Agent. Regardless of the source
of the funds actually used by the Agent to fund any portion of the Advances
subject to a LIBOR Pricing Option, all amounts payable hereunder, including the
interest rate applicable to any such portion of the Advances and the amounts
payable under Sections 2.6 and 2.7, shall be computed as if the Agent had
actually funded such portion of the Advances through the purchase of deposits in
such amount of the type by which the LIBOR Rate was determined with a maturity
the same as the applicable LIBOR Interest Period relating thereto and through
the transfer of such deposits from an office of the Bank having the same
location as the applicable LIBOR Office to one of the Agent's offices in the
United States of America.

     2.3  COMMITMENT FEE. The Company shall pay to the Agent for the ratable
benefit of the Banks during the Credit Period a commitment fee computed at the
rate of two tenths of one percent (0.20%) per annum on the average daily amount
of (i) the unborrowed portion of the Maximum Revolving Credit and (ii) the
unused portion of the Maximum Equipment Credit, during each or portion thereof.
Commitment fees shall be payable quarterly in arrears, on the first day of each
March, June, September and December beginning June 1, 1997, and ending on the
last day of the Credit Period. The Company may by thirty (30) days prior written
notice to the Bank reduce the Maximum Revolving Credit or Maximum Equipment
Credit at any time after 90 days from the date of this Agreement. Any such
reduction shall be permanent.

     2.4  THE NOTE

          (a) The Loans shall be evidenced by the Notes, payable to the order of
each Bank. Each Note shall be in the original amount of the applicable Bank's
commitment percentage of the Maximum Credit. Each Note shall be dated on or
before the date of the first Loan and shall have the blanks therein
appropriately completed.

          (b) Each Bank shall, and is hereby irrevocably authorized by the
Company to, enter on the schedule forming a part of the Note or otherwise in its
records appropriate notations evidencing the date and the amount of each Loan
and the date and amount of each payment of principal made by the Company with
respect thereto; and in the absence of manifest error, such notations shall
constitute conclusive evidence thereof. The Agent will provide the Company with
a monthly statement of all Loans made to and payments by the Company and all
interest charged on the Loans. Each Bank is hereby irrevocably authorized by the
Company to attach to and make a part of the Note a continuation of any such
schedule as and when required. No failure on the part of the Banks to make any
notation as provided in this subsection (b) shall in


                                       11
<PAGE>   16

any way affect any Loan or the rights or obligations of the Banks or the Company
with respect thereto.

     2.5 INTEREST RATES AND PAYMENTS OF INTEREST. Subject to the terms of this
Agreement relating to LIBOR Pricing Options, each Loan shall bear interest on
the outstanding principal amount thereof at a rate per annum equal to the
Alternate Base Rate, which rate shall change contemporaneously with any change
in the Base Rate. Such interest shall be payable on the first day of each month,
commencing August 1, 1997 and when such Loan is due (whether at maturity, by
reason of acceleration or otherwise). The Agent may, and the Company hereby
authorizes the Agent to, debit the amount of any payments not made by such time
to the demand deposit account of the Company with the Agent.

     2.6 CERTAIN PROVISIONS RELATING TO LIBOR PRICING OPTION.

               (a) If any portion of the Advances subject to a LIBOR Pricing
Option is repaid, or any LIBOR Pricing Option is terminated for any reason
(including acceleration of maturity, but excluding a Legal Requirement not
having the force of law), on a date which is prior to the last Business Day of
the LIBOR Interest Period applicable to such LIBOR Pricing Option, the Company
will pay to the Agent, in addition to any amounts of interest otherwise payable
hereunder, an amount equal to the present value (calculated in accordance with
this Section 2.6) of interest for the unexpired portion of such LIBOR Interest
Period on the portion of the Loan so repaid, or as to which a LIBOR Pricing
Option was so terminated, at a per annum rate equal to the excess, if any, of
(i) the LIBOR Rate applicable to such LIBOR Pricing Option MINUS (ii) the LIBOR
Rate then applicable to a deemed LIBOR Interest Period having a maturity date
approximating the last Business Day of such LIBOR Interest Period. The present
value of such additional interest shall be calculated by discounting the amount
of such interest for each day in the unexpired portion of such LIBOR Interest
Period from such day to the date of such repayment or termination at a per annum
interest rate equal to the interest rate determined pursuant to clause (ii) of
the preceding sentence, and by adding all such amounts for all such days during
such period. The determination by the Agent of such amount of interest shall, in
the absence of manifest error, be conclusive. For purposes of this Section 2.6,
if any portion of the Advances which was to have been subject to a LIBOR Pricing
Option is not outstanding on the first day of the LIBOR Interest Period
applicable to such LIBOR Pricing Option other than for reasons described in
Section 2.2(c), the Company shall be deemed to have terminated such LIBOR
Pricing Option.

          (b) If any Legal Requirement shall prevent any of the Banks from
funding or maintaining through the purchase of deposits in the London inter-bank
market any portion of the Advances subject to a LIBOR Pricing Option or
otherwise from giving effect to such Bank's obligations as contemplated by
Section 2.2(c), then not earlier than the latest day permitted by such Legal
Requirement, (i) such Bank may by notice to the Company terminate all of the
affected LIBOR Pricing Options, (ii) the portion of the Advances subject to such
terminated LIBOR Pricing Options shall immediately be converted to Base Loans
and (iii) the Company shall make any payment required by paragraph (a) above.

     2.7  CHANGES IN CIRCUMSTANCES; YIELD PROTECTION.

          (a) If any Legal Requirement shall (i) impose, modify, increase or
deem applicable any insurance assessment, reserve, special deposit or similar
requirement against any Funding Liability, (ii) impose, modify, increase or deem
applicable any other requirement or condition with respect to any Funding
Liability, or (iii) change the basis of taxation of Funding Liabilities (other
than changes in the rate of taxes measured by the overall net income of any such
Bank) and the effect of any of the foregoing shall be to increase the cost to
such Bank of issuing, making, funding or maintaining any portion of an Advance
subject to a LIBOR Pricing Option, to reduce the amounts received or receivable
by such Bank under this Agreement or to require such Bank to make any payment or
forego any amounts otherwise payable to the Bank under this


                                       12
<PAGE>   17

Agreement (other than any Tax or any reserves that are included in computing the
Reserve Requirement), such Bank may claim compensation from the Company under
paragraph (e) below.

          (b) All payments of the Obligations shall be made without set-off or
counterclaim and free and clear of any deductions, including deductions for
Taxes, unless the Company is required by law to make such deductions. If (i) any
of the Banks shall be subject to any Tax with respect to any payment of the
Obligations or its obligations hereunder, or (ii) the Company shall be required
to withhold or deduct any Tax on any payment of the Obligations, then such Bank
may claim compensation from the Company under paragraph (e) below. Whenever
Taxes must be withheld by the Company with respect to any payment of the
Obligations, the Company shall promptly furnish to the Agent official receipts
(to the extent that the relevant governmental authority delivers such receipts)
evidencing payment of any such Taxes so withheld. If the Company fails to pay
any such Taxes when due or fails to remit to the Agent the required receipts
evidencing payment of any such Taxes so withheld or deducted, the Company shall
indemnify such Bank for any incremental Taxes and interest or penalties that may
become payable by such Bank as a result of any such failure. In the event the
Bank receives a refund of any Taxes for which it has received payment from the
Company under this Section 2.7(b), such Bank shall promptly pay the amount of
such refund to the Company, together with any interest thereon actually earned
by such Bank.

          (c) If any of the Banks shall determine in good faith that compliance
by such Bank with any change in Legal Requirements after the date hereof
regarding capital adequacy of banks or bank holding companies has or would have
the effect of reducing the rate of return on the capital of such Bank as a
consequence of such Bank's commitment to make the extensions of credit
contemplated hereby, to a level below that which such Bank could have achieved
but for such compliance (taking into consideration the policies of such Bank
with respect to capital adequacy immediately before such compliance and assuming
that the capital of such Bank was fully utilized prior to any such compliance)
by an amount deemed by such Bank to be material, then such Bank may claim
compensation from the Company under paragraph (e) below.

          (d) If any of the Banks shall determine in good faith that (i) any
change in any Legal Requirement (including any new Legal Requirement) after the
date hereof shall directly or indirectly (A) reduce the amount of any sum
received or receivable by such Bank with respect to an Advance or the return to
be earned by such Bank on an Advance, (B) impose an additional cost on such Bank
that is attributable to the making or maintaining of, or such Bank's commitment
to make, its portion of an Advance or (C) require such Bank to make any payment
on, or calculated by reference to, the gross amount of any amount received by
such Bank under any of the Loan Documents (other than Taxes or income or
franchise taxes), and (ii) such reduction, increased cost or payment shall not
be fully compensated for by an adjustment in the interest rate on the Advances,
then such Bank may claim compensation from the Company under paragraph (e)
below.

          (e) Within 15 days after the receipt by the Company of a certificate
from any of the Banks setting forth why it is claiming compensation under this
Section 2.7 and computations (in reasonable detail) of the amount thereof, the
Company shall pay to such Bank such additional amounts as such Bank sets forth
in such certificate as sufficient fully to compensate it on account of the
foregoing provisions of this Section 2.7, together with interest on such amount
from the 15th day after receipt of such certificate until payment in full
thereof at the Base Rate. The determination by such Bank of the amount to be
paid to it and the basis for computation thereof hereunder shall be presumed
correct unless rebutted by clear evidence. In determining such amount, such Bank
may use any reasonable averaging and attribution methods.

          (f) The Banks shall take such commercially reasonable steps as they
may determine are not materially disadvantageous to it, including changing
lending offices to the extent


                                       13
<PAGE>   18

feasible, in order to reduce amounts otherwise payable by the Company to the
Banks pursuant to this Section 2.7 or to make LIBOR Pricing Options available
under Section 2.2. In addition, the Company shall not be responsible for costs
(i) under this Section 2.7 arising more than 90 days prior to receipt by the
Company of the certificate from the Bank pursuant to this Section 2.7 or (ii)
under Section 2.6 from the termination of LIBOR Pricing Options occurring more
than 90 days prior to the demand by the Bank for payment under Section 2.6.

     2.8  CAPITAL REQUIREMENTS. If after the date hereof any of the Banks
determines in good faith that (i) the adoption of or change in any law, rule,
regulation or guideline of any applicable governmental authority regarding
capital requirements for banks or bank holding companies, or any change in the
interpretation or application thereof by any governmental authority charged with
the administration thereof, or (ii) compliance by such Bank or its parent bank
holding company with any guideline, request or directive of any such entity
regarding capital adequacy (whether or not having the force of law), has the
effect of reducing the return on such Bank's or such holding company's capital
as a consequence of such Bank's commitment to make Loans hereunder to a level
below that which such Bank or such holding company could have achieved but for
such adoption, change or compliance (taking into consideration such Bank's or
such holding company's then existing policies with respect to capital adequacy
and assuming the full utilization of such entity's capital) by any amount deemed
by such Bank to be material, then such Bank shall notify the Company thereof.
The Company agrees to pay to such Bank the amount of such reduction of capital
as and when such reduction is determined, upon presentation by such Bank of a
statement in the amount and setting forth such Bank's calculation thereof, which
statement shall be presumed correct unless rebutted by clear evidence. In
determining such amount, such Bank may use any reasonable averaging and
attribution methods.
       
     2.9  PAYMENTS AND PREPAYMENTS OF THE LOANS. Loans outstanding in excess of
the Borrowing Base or in excess of the Maximum Revolving Credit, shall be paid
immediately without notice or demand. All Loans shall be paid without notice or
demand on the Termination Date, or earlier as provided in Section 7.2 upon the
occurrence of an Event of Default. Loans may be prepaid at any time, without
premium or penalty, upon one Business Day's notice. Any interest accrued on the
amounts so prepaid to the date of such payment must be paid at the time of any
such payment. No prepayment of the Loans during the Credit Period shall affect
the Commitment Amount or impair the Company's right to borrow as set forth in
Section 2.1.

     2.10 METHOD OF PAYMENT. All payments and prepayments of principal and all
payments of interest shall be made by the Company to the Agent at its head
office in Boston, Massachusetts in immediately available funds, on or before
10:00 a.m. Boston time on the due date thereof, free and clear of, and without
any deduction or withholding for, any taxes or other payments. The Agent may,
and the Company hereby authorizes the Agent to, debit the amount of any payment
not made by such time to the demand deposit account of the Company with the
Agent.

     2.11 OVERDUE PAYMENTS. Overdue principal (whether at maturity, by reason of
acceleration or otherwise) and, to the extent permitted by applicable law,
overdue interest and fees or any other amounts payable hereunder or under the
Note shall bear interest from and including the due date thereof until paid at a
rate per annum equal to 4% above the rate then applicable to Loans, which
interest shall be payable on demand.

     2.12 COMPUTATION OF INTEREST AND FEES. Interest and all fees payable
hereunder shall be computed daily on the basis of a year of 360 days and paid
for the actual number of days for which due. If the due date for any payment of
principal is extended by operation of law, interest shall be payable for such
extended time. If any payment required by this Agreement becomes due on a day
that is not a Business Day such payment may be made on the next succeeding
Business Day, and such extension shall be included in computing interest in
connection with such payment. For the purposes of computing interest, all
payments will be credited to the Loans one


                                       14
<PAGE>   19

(1) Business Day after receipt by the Agent.

     2.13 BORROWING BASE REPORTS. The Company shall deliver a Borrowing Base
Report and an aging report monthly prepared as of the close of business at the
end of the preceding month within thirty (30) days after the end of such month;
provided, however, that (i) the Borrowing Base Report shall only be delivered
quarterly (thirty (30) days after the end of such quarter) if there are no
outstanding Advances at the end of any month that is not at the end of a fiscal
quarter and (ii) the Banks may require more frequent reports during the
occurrence of a Default.

     2.14 AGENT'S FEE. The Company shall pay to the Agent on the Closing Date an
agency fee as previously agreed. Such fee shall be fully earned upon the date
due and shall not be pro rated in the event of a reduction in or termination of
the Commitment Amount.

     2.15 FIELD AUDIT EXPENSES. The Company shall pay to the Agent on demand the
Agent's customary fee for audit reviews by employees of the Agent (currently
$350 per day plus out-of-pocket expenses); provided that, unless an Event of
Default shall exist, the Company shall not be obligated to pay for more than one
audit in any fiscal year of the Company.

                                   -----------

                               CONDITIONS OF LOANS

<PAGE>   20

     3.2  CONDITIONS PRECEDENT TO ALL LOANS. The obligation of the Banks to make
each Loan, including the initial Loan, is further subject to the following

would make it illegal or against the policy of any governmental agency or
authority for the Banks to make Loans hereunder and no material adverse change
in the performance, prospects or ownership of the Company.

     The making of each Loan shall be deemed to be a representation and warranty
by the Company on the date of the making or continuation of such Loan as to the
accuracy of the facts referred to in subsection (b) of this Section 3.2.


                                   SECTION IV
                                   ----------

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

     In order to induce the Banks and Agent to enter into this Agreement and for
the Banks to make Loans and provide equipment financing hereunder, the Company
represents and warrants to the Banks and Agent that:

     4.1  ORGANIZATION AND QUALIFICATION.. Each of the Company and its
Subsidiaries (a) is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation, (b) has all
requisite corporate power to own its property and conduct its business as now
conducted and as presently contemplated and (c) is duly qualified and in good
standing as a foreign corporation and is duly authorized to do business in each
jurisdiction where the nature of its properties or business requires such
qualification, except for such jurisdictions in which such failure to be so
qualified will not have a material adverse effect on the Company and its
Subsidiaries taken as a whole.

     4.2  CORPORATE AUTHORITY. The execution, delivery and performance of this
Agreement and the other Loan Documents and the transactions contemplated hereby
are within the corporate power and authority of the Company and have been
authorized by all necessary corporate proceedings, and do not and will not (a)
require any consent or approval of the stockholders of the Company, (b)
contravene any provision of the charter documents or by-laws of the Company or
any law, rule or regulation applicable to the Company, (c) contravene any
provision of, or constitute an event of default or event that, but for the
requirement that time elapse or notice be given, or both, would constitute an
event of default under, any other material agreement, instrument, order or
undertaking binding on the Company, or (d) result in or require the imposition
of any Encumbrance on any of the properties, assets or rights of the Company.

     4.3  VALID OBLIGATIONS. This Agreement and the other Loan Documents and all
of 


                                       16
<PAGE>   21

their respective terms and provisions are the legal, valid and binding
obligations of the Company, enforceable against the Company in accordance with
their respective terms except as limited by bankruptcy, insolvency,
reorganization, moratorium or other laws affecting the enforcement of creditors'
rights generally, and except as the remedy of specific performance or of
injunctive relief is subject to the discretion of the court before which any
proceeding therefor may be brought.

     4.4  CONSENTS OR APPROVALS. The execution, delivery and performance of this
Agreement and the other Loan Documents and the transactions contemplated herein
do not require any approval or consent of, or filing or registration with, any
governmental or other agency or authority, or any other party.

     4.5  TITLE TO PROPERTIES; ABSENCE OF ENCUMBRANCES. Each of the Company and
its Subsidiaries has good and marketable title to all of the properties, assets
and rights of every name and nature now purported to be owned by it, including,
without limitation, such properties, assets and rights as are reflected in the
financial statements referred to in Section 4.6 (except such properties, assets
or rights as have been disposed of in the ordinary course of business since the
date thereof), free from all Encumbrances except Permitted Encumbrances or those
Encumbrances disclosed in EXHIBIT E hereto, and, except as so disclosed, free
from all defects of title that might materially adversely affect such
properties, assets or rights, taken as a whole.

     4.6  FINANCIAL STATEMENTS. The Company has furnished the Bank its
consolidated balance sheet as of July 31, 1996 and its consolidated statements
of income, changes in stockholders' equity and cash flow for the fiscal year
then ended, and related footnotes, audited and certified by Arthur Andersen LLP.
The Company has also furnished the Bank its consolidated balance sheet as of
April 30, 1997 and its consolidated statements of income, changes in
stockholders equity and cash flow for the fiscal period then ended, certified by
the principal financial officer of the Company but subject, however, to the
absence of footnotes and normal, recurring year-end adjustments that are not
reasonably expected in the aggregate to be material in amount. All such
financial statements were prepared in accordance with generally accepted
accounting principles applied on a consistent basis throughout the periods
specified and present fairly in all material respects the financial position of
the Company and its Subsidiaries on a consolidated basis as of such date and the
results of the operations of the Company and its Subsidiaries on a consolidated
basis for such period. There are no known liabilities, contingent or otherwise,
not disclosed in such financial statements that involve a material amount.

     4.7  CHANGES. Since the date of the most recent financial statements
referred to in Section 4.6, there have been no changes in the assets,
liabilities, financial condition, or business of the Company or any of its
Subsidiaries other than changes in the ordinary course of business, the effect
of which has not, in the aggregate, been materially adverse to the Company and
its Subsidiaries taken as a whole.

     4.8  DEFAULTS. As of the date of this Agreement, no Default exists.

     4.9  TAXES. The Company and each Subsidiary have filed all federal, state
and other tax returns required to be filed by it, and all taxes, assessments and
other governmental charges due from the Company and each Subsidiary have been
fully paid except (i) for taxes, the validity of which are being contested in
good faith by appropriate proceedings diligently pursued and available to the
Company or its Subsidiary (as the case may be) with respect to which adequate
reserves have been set aside on their books and (ii) to the extent failure to
have filed any such return or paid any such amount will not have a material
adverse effect on the Company and its Subsidiaries taken as a whole. The Company
has established on its books reserves adequate for the payment of all federal,

No delay or omission on the Agent's or any Bank's part in exercising its rights
and remedies against the Company or any other interested party shall constitute
a waiver. The waiver of the Company's breach in one or more instances shall not
constitute or otherwise be an implicit waiver of subsequent breaches. To the
extent permitted by applicable law, the Company hereby agrees to waive, and does
hereby absolutely and irrevocably waive (i) all presentments, demands for
performance, notices of nonperformance, protests, notices of protest and notices
of dishonor in connection with any of the Indebtedness evidenced by the Note,
(ii) any requirement of diligence or promptness on the Agent's or any Bank's
part in the enforcement of its rights under the provisions of this Agreement or
any Loan Document, and (iii) except for such notices as are specifically
required under this Agreement, any and all notices of every kind and description
which may be required to be given by any statute or rule of law with respect to
its liability (A) under this Agreement or in respect of the Indebtedness
evidenced by the Note or any other Obligation, or (B) under any other Loan
Document. No course of dealing between the Company and the Agent or any Bank
shall operate as a waiver of any of the Agent's or any Bank's rights under this

Agent's and the Banks rights and remedies under this Agreement and under all
subsequent agreements between the Agent, the Banks, or the Company shall be
cumulative and any rights and remedies expressly set forth herein shall be in
addition to, and not in limitation of, any other rights and remedies which may
be available to the Agent and the Banks in law or at equity.


                                   SECTION IX
                                   ----------

                                    THE AGENT
                                    ---------

     9.1  APPOINTMENT OF AGENT. Each Bank by becoming a party to this Agreement
does hereby appoint, and consent to the appointment of, the Agent as agent for
the ratable benefit of the Banks hereunder. The Agent is authorized to take such
action on behalf of each of the Banks and to exercise all such powers as are
hereunder and in related documents delegated to the Agent, together with such
powers as are reasonably incidental thereto.

Company.

directors, officers or employees nor any other Person assisting them in their
duties nor any agent or employee of any such person, shall be liable for any
waiver, consent or approval given or any action taken, or omitted to be taken,
in good faith by it or them hereunder, or in connection herewith or therewith,
or be responsible for the consequences of any oversight or error of judgment
whatsoever, except that the Agent or such other Person, as the case may be, may
be liable for losses due to its willful misconduct or gross negligence.

     9.4  RESPONSIBILITIES. The Agent shall not be responsible for the execution
or validity or enforceability of this Agreement, or any instrument at any time
constituting, or intended to constitute, collateral security for the Loans, or
for the value of any such collateral security or for the validity,
enforceability or collectibility of any such amounts owing with respect to the
Loans, or for any recitals or statements, warranties or representations herein
or made in any certificate or instrument hereafter furnished to it by or on
behalf of the Company, or be bound to ascertain or inquire as to the performance
or observance of any of the terms, conditions, covenants or agreements herein or
in any instrument at any time constituting, or intended to constitute,
collateral security for the Loans. The Agent shall not be bound to ascertain

consent, waiver or request delivered to it by the Company or any holder of any
of the Loans shall have been duly authorized or is true, accurate and complete.

express or implied, nor does it assume any liability to the Banks with respect
to the creditworthiness or financial condition of the Company or any of its
Subsidiaries and each Bank represents and warrants to the Agent that it has made
its own independent evaluation of the creditworthiness of the Company and its
Subsidiaries and has a not relied upon the Agent or any material or information
furnished by the Agent in making such evaluation.

     9.5  DIRECTION BY COURT. If, in the opinion of the Agent, the distribution
of any amount received by it in such capacity hereunder might involve it in
liability, it may refrain from making distribution until its right to make
distribution shall have been adjudicated by a court of competent jurisdiction.
If a court of competent jurisdiction shall adjudge that any amount received and
distributed by the Agent is to be repaid, each person to whom any such
distribution shall have been made shall either repay to the Agent its
proportionate share of the amount so adjudged to be repaid or shall pay over the
same in such manner and to such Persons as shall be determined by such court.
With respect to obligations of the Company hereunder, a payment to the Agent
shall be deemed to be payment to the Banks.

     9.6  TREATMENT OF PAYEES. The Agent may deem and treat the payee of any
Note as the absolute owner thereof for all purposes hereof until it shall have
been furnished in writing with a different name by such payee or by a subsequent
holder.

     9.7  AGENT AS BANK. In its individual capacity, BankBoston, N.A. shall have
the same obligations and the same rights, powers and privileges in respect to
its Commitment Amount and the Loans made by it hereunder, as it would have were
it not also the Agent.

     9.8  SHARING OF COSTS AND EXPENSES. To the extent not paid by the Company,
each Bank agrees to pay its proportionate share of all costs and expenses
incurred by the Agent in its capacity as Agent hereunder, in accordance with the
respective Commitment Amounts of the Banks hereunder. The costs and expenses to
be shared by the Banks pursuant to this Section 9.8 shall not include any costs
or expenses incurred by the Agent as an individual Bank in connection with the
Loans made by it.

$8,000,000                                                 Boston, Massachusetts
                                                           June __, 1997


     For value received, the undersigned hereby promises to pay to BankBoston,
N.A. (the "Bank"), or order, at the head office of the Bank at 100 Federal

($8,000,000) or such lesser amount as shall equal the principal amount of the
Loans outstanding hereunder on June __, 1998 (the "Termination Date") in lawful
money of the United States of America and in immediately available funds, and to
pay interest on the unpaid principal balance hereof from time to time
outstanding, at said office and in like money and funds, (i) in the case of a
Base Rate Loan, at a rate per annum which shall at all times equal the Alternate
Base Rate and (ii) in the case of a LIBOR Rate Loan, at a rate per annum equal
to the Applicable LIBOR Rate. Except as otherwise set forth in the Credit
Agreement with respect to Applicable Libor Rate Loans, interest shall be payable
in arrears on the first day of each month beginning on August 1, 1997 and when
the principal balance hereof is due (whether at maturity, by reason of
acceleration or otherwise).

     The terms "Loans", "Alternate Base Rate" and "Base Rate" shall have the
meanings set forth in the Agreement referred to below. The rate of interest
shall vary from time to time as the Alternate Base Rate varies, and any change
in the rate of interest will become effective on the effective date of a change
in the Base Rate. The term "Applicable LIBOR Rate" shall have the meaning set
forth in the Agreement referred to below. Interest shall be computed on the
basis of a 360-day year for the actual number of days elapsed.

     Overdue payments of principal (whether at stated maturity, by acceleration
or otherwise), and, to the extent permitted by law, overdue interest, shall bear
interest, at a rate per annum equal to four percent (4%) above the rate that
would otherwise be applicable to principal hereunder. Nothing in the preceding
sentence shall affect the rights of the Bank or Agent (as defined in the
Agreement) to exercise any of their rights and remedies provided in the
Agreement (as defined below) if an Event of Default (as defined in the
Agreement) has occurred.

     This Note is issued pursuant to, and entitled to the benefits of, and is
subject to, the provisions of a certain Credit Agreement dated as of June __,
1997 by and between the undersigned, the Agent and the Banks (herein, as the
same may from time to time be amended or extended, referred to as the
"Agreement"), but neither this reference to the Agreement nor any provision
thereof shall affect or impair the absolute and unconditional obligation of the
undersigned maker of this Note to pay the principal of and interest on this Note
as herein provided.

     In case an Event of Default (as defined in the Agreement) shall occur, and
be continuing, the aggregate unpaid principal of and accrued interest on this
Note shall become or may be declared to be due and payable in the manner and
with the effect provided in the Agreement.

of this Note before maturity upon the terms provided in the Agreement.

hereunder, and subject to the full performance of all such services, Employer
shall pay to the employee a base salary (the "Base Salary") at the annual rate
of $226,000, payable in conformity with the Employer's regular payroll dates for
salaried personnel. In addition to the Base Salary, Employer shall pay to the
Employee, within forty-five (45) days following the close of the fiscal year
ending July 31, 1997 an annual cash bonus (the "Bonus") if the Company's income
before income taxes and minority interest, without regard to inventory and
restructuring charges ("Pretax Income") for fiscal 1997 is at least $1,100,000.
The amount of the Bonus shall be $50,000 plus 1.667% of Pretax Income in excess
of $1,100,000 up to a maximum total Bonus for fiscal 1997 of $150,000. During
the Employment Period, the Compensation Committee of the Board of Directors of
the Employer shall review the Base Salary and Bonus for the purpose of
determining increases to the Base Salary and Bonus at the time of review of
compensation of other executive officers of the Employer.

          b. SPECIAL BONUS, TERMINATION BY EMPLOYEE. In the event that a Change
of Control (as hereinafter defined) shall occur, then the Employee may, at his
election, terminate his employment hereunder and this Agreement upon written
notice given at any time not earlier than six (6) months after nor later than
twelve (12) months after the occurrence of such event. In the event the Employee
voluntarily terminates his employment with Employer in accordance with the
foregoing sentence, then at or before the Employee's last day of employment with
the Employer, the Employer will pay to the Employee as compensation for services
rendered to the Employer, a lump sum cash amount equal to the then current
annual Base Salary. For the purposes of this provision a "Change of Control"
shall be deemed to have taken place if (a) a party other than Employer or
Employee, including a "Group" as defined in Section 13(d)(3) of the Securities
Act of 1934, acquires shares of the Employer, with the result that such party
then owns a majority of the total number of votes that may be cast for the
election of directors of the Employer, or (b) as a result of any cash tender or
exchange offer, merger or other business combination or transactions
("Transaction"), the persons who were directors of the Employer before the
Transaction cease to constitute a majority of the Board of Directors of the
Employer or any successor to the Employer.

          c. FRINGE BENEFITS. Employee shall be entitled to such fringe benefits
as are set forth in the attached EXHIBIT A, which EXHIBIT A is incorporated by
reference herein.

                                      -2-

     4. EXPENSES. Employer shall reimburse Employee for reasonable business
expenses incurred in direct furtherance of the business of Employer in
accordance with the Employer's standard expense policy.

     5. VACATIONS. Employee shall be entitled to an annual vacation of four (4)
weeks in accordance with the Employer's standard policy, during which time his
Base Salary shall be paid and his bonus compensation shall continue to accrue.

     6. TERMINATION. Notwithstanding the provisions of paragraph 1, Employee's
employment under this Agreement shall terminate prior to the expiration of the
Initial Term, or thereafter, under the following circumstances:

          a. DEATH: Upon the death of the Employee;

          b. DISABILITY: Upon the permanent disability of the Employee. For
purposes of this Section 6.b "permanent disability" shall mean the substantial
inability of the Employee, due to illness or physical or mental disability, to
perform his duties as an officer or employee if such inability is likely to
continue for a period of more than one hundred eighty (180) continuous days. The
determination of permanent disability shall be made by mutual agreement of the
parties or, if they cannot agree, by a physician or psychiatrist acceptable to
both the Employer and Employee. If the parties cannot agree upon the selection
of a physician or psychiatrist, each shall select an arbitrator in accordance
with the commercial arbitration rules of the American Arbitration Association,
and such arbitrator shall select a physician or psychiatrist. In either case,
the opinion of such physician or psychiatrist shall be binding on and
non-appealable by the parties. The Employer or Employee may request an
examination, and the Employee shall submit to examination at reasonable times
and under reasonable conditions. For purposes hereof, a continuous period of
incapacity shall be deemed interrupted when the employee returns to
substantially full-time work for a continuous period of at least five (5)
business days;

          c. BY THE EMPLOYEE UPON A CHANGE OF CONTROL: Upon an election by the
Employee to terminate this Agreement following a Change of Control, as provided
in Paragraph 3.b;

          d. BY THE EMPLOYEE UPON WRITTEN NOTICE: Upon thirty (30) days prior
written notice by Employee;

          e. BY THE EMPLOYER FOR CAUSE: The Employer shall have the right to
terminate this Agreement and Employee's employment for cause immediately and
without prior written notice. For purposes of this Paragraph 6.e, the following
shall constitute "cause" for termination by the Employer:


                                      -3-

<PAGE>   4

               (1)  Employee's repeated or willful failure or unwillingness to
                    perform the responsibilities of his position or such duties
                    and responsibilities as shall be reasonably assigned to him
                    by the Employer's President;

               (2)  theft, embezzlement, fraud, or other criminal conduct or
                    dishonesty occurring in connection with the Employee's
                    performance of his duties hereunder;

               (3)  Employee's prolonged or repeated unexcused absences from
                    duty without the consent of the Employer;

               (4)  willful violation by the Employee of any material provision
                    of this Agreement or violation of any written policy of the
                    Employer.

Upon termination of the Employee's employment for cause or under any of the
circumstances described in Paragraphs 6.a, 6.b or 6.d, the Employee shall be
entitled to receive only his Base Salary through the date of termination of
employment, and the Employee shall not be entitled to any other or further
compensation, bonus, severance or other fringe benefits except as otherwise
explicitly provided by law.

          f. BY THE EMPLOYER WITHOUT CAUSE: The Employer may at any time upon
thirty (30) days prior written notice or payment in lieu of notice terminate the
Employee's employment without cause. In the event of a termination without cause
during the Initial Term, the Employee shall continue to receive his Base Salary
for the remainder of the Initial Term, and the Employee shall receive in
addition thereto severance payments at his then Base Salary for a period of one
year beyond the Initial Term. If the Employer terminates the Employee's
employment without cause after the Initial Term, then, notwithstanding that the
employment may be otherwise "at will", the Employee shall receive severance
payments at his then Base Salary for a period of one year from the date of
termination. Notwithstanding any other provision of this Paragraph 6.f, it shall
be a condition of the Employee's receipt of severance payments under this
Paragraph that, upon termination, the Employee execute a general release of
claims against the Employer in a form reasonably satisfactory to counsel for the
Employer.

     7. NON-COMPETITION. During the Employment Period and for a period of six
(6) months following the end of the Employment Period, Employee shall not,
directly or indirectly (as owner, partner, director, trustee, agent, employee or
otherwise), establish or engage in any business which sells any item of
manufacture which is similar to or used in connection with the products
manufactured by Employer during the one (1) year period ending on the date of
termination of this Agreement. The Employee will not be deemed 


                                      -4-
<PAGE>   5

to have breached his obligations under this Paragraph 7 if (i) he shall have
notified the Employer in writing at least thirty (30) days prior to any proposed
new employment, investment or other business relationship of the name of the
proposed new employer or person, firm, corporation, association or other entity
and the nature of his duties, investment or business relationship, and (ii) the
Employer shall have failed to notify him in writing within fifteen (15) days
after its receipt of such notice from him that it considers such employment,
investment or relationship in violation of any provision of this Paragraph 7; or
if, in the case of passive ownership only, the Employee's equity interest in the
aggregate is less than ten percent (10%) of the value of all outstanding shares
of capital stock or other evidence of equitable ownership of such person, firm,
corporation, association, or other entity, whether such class of equitable
ownership is privately held or publicly traded.

     8. NON-INTERFERENCE WITH EMPLOYEES. During the Employment Period and for a
period of one (1) year from the end of the Employment Period, the Employee will
not, without the Employer's prior written approval, engage the services of any
employee of the Employer, whether as employee, consultant, agent or otherwise,
for any business (other than the business of Employer) in which he might be
associated as owner, stockholder, partner, consultant, employee, agent or
otherwise.

     9. NON-INTERFERENCE WITH CUSTOMERS. During the Employment Period, and for a
period of six (6) months following the end of the Employment Period, the
Employee agrees not, without the Employer's prior written approval, to perform
services (other than in the capacity as agent of the Employer), whether as an
employee, consultant, agent, or otherwise, for any then-existing customer or
client of the Employer.

     10. CONFIDENTIAL INFORMATION. The Employee agrees never, directly or
indirectly, to use, publish, disseminate or otherwise disclose any confidential
information without the prior written consent of the Employer. For the purposes
of this Agreement, "confidential information" shall mean that secret proprietary
information of the Employer of whatever kind or nature disclosed to or known by
the Employee (whether or not invented, discovered or developed by the Employee)
as a consequence of or through his employment by the Employer, including,
without limitation, sources of supply and material, operating and other cost
data, lists of present, past or prospective clients or customers, pricing
information, and records of the Employer, particularly those legended or
otherwise identified by the Employer as confidential information.

     11. RETURN OF DOCUMENTS. Upon termination of the Employee's employment for
any reason, all documents, procedural manuals, guides, specifications, plans,
drawings, designs and similar materials, lists of present,


                                      -5-
<PAGE>   6

past or prospective clients or customers, client or customer proposals,
invitations to submit proposals, price lists and data relating to pricing of the
Employer's products and services, records, notebooks and similar repositories of
or containing confidential information, including all copies thereof, then in
the Employee's possession or control, whether prepared by the Employee or
others, will be left with or forthwith returned by the Employee to the Employer.

     12. SURVIVAL; REMEDIES. The duties and obligations of Employee under
Paragraphs 7 through 11, inclusive, of this Agreement shall survive the
termination of the Employee's employment with the Employer. The Employee
acknowledges that a remedy at law for any breach or threatened breach by the
Employee of Paragraphs 7 through 11 of this Agreement may be inadequate, and the
Employee therefore agrees that the Employer shall be entitled, without limiting
any other of its legal rights, to injunctive relief and other equitable remedies
in case of any such breach or threatened breach.

     13. RESTRICTION AGAINST EMPLOYEE ASSIGNMENT. The services to be rendered by
Employee pursuant to this Agreement are personal in nature and therefore the
Employee shall not assign or transfer this Agreement or any rights or
obligations hereunder without the written consent of Employer.

     14. NOTICES. All notices required hereunder or voluntarily given shall be
in writing and shall be deemed given when personally delivered or when sent by
registered or certified mail, return receipt requested, postage prepaid,
addressed to the party for which it is intended at their following respective
address, or at such other address as either party may designate to the other by
like notice:

     If to Employer:   Attn: President
                       LTX Corporation
                       5 Rosemont Road

                       Los Gatos, California 95032

     15. GOVERNING LAW. This Agreement shall be construed and governed by the
laws of the Commonwealth of Massachusetts exclusive of conflict of law
principles.

     16. SEVERABILITY. In case any one or more of the provisions contained in
this Agreement shall, for any reason, be held to be invalid, illegal or
unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provisions of this Agreement, but this Agreement
shall be construed as if such invalid, illegal or unenforceable provisions had
never been contained herein. If, moreover, any provision contained in this
Agreement shall for any reason be held to be excessively broad as to duration,


                                      -6-
<PAGE>   7

geographical scope, activity or subject matter, such provision shall be
construed by limiting and reducing it by the minimum extent necessary to render
it enforceable under applicable law.

     17. BENEFIT; PERSONS BOUND. This Agreement shall inure to the benefit of
and bind the Employer and Employee and their respective heirs, executors,
administrators, successors and permitted assigns, if any.

     18. CONSTRUCTION. The headings in this Agreement are for purposes of
reference only and shall not be considered in construing this Agreement.

     19. ARBITRATION. In the event of any dispute between the parties hereto
arising out of the Employee's employment or relating to the validity,
construction, enforcement or performance of this Agreement, such dispute shall
be settled by arbitration before a single arbitrator conducted at Boston,
Massachusetts, in accordance with the Commercial Arbitration Rules of the
American Arbitration Association. The decision of the arbitrator shall be final
and binding on all parties thereto, and judgment upon any award entered in such
proceeding may be entered in any court having jurisdiction thereof. Each party
to such arbitration shall pay one-half of all costs and expenses of such
arbitration and each such party shall pay their respective attorneys' fees. The
determination of the arbitrator shall be conclusive on the matter of which party
is successful for purposes hereof.

     In no event, however, shall this Paragraph 19 be deemed to preclude a party
hereto from instituting legal action seeking relief in the nature of a
restraining order, an injunction or the like in order to protect his or its
rights pending the outcome of an arbitration hereunder. With respect to matters
submitted to arbitration other than claims for payment of monies due, the
parties shall continue to perform their obligations hereunder relative to said
matters pending resolution of the dispute by arbitration.

     20. INDEMNIFICATION. During and after the term of this Agreement, the
Employer will indemnify the Employee against all claims brought against him
which arise in the course of his employment by the Employer pursuant to this
Agreement to the maximum extent permitted under the laws of the Commonwealth of
Massachusetts, notwithstanding any provision of the By-laws of the Employer or
any action by the Board of Directors of the Employer, either before or after the
Employment Date, which is to the contrary or inconsistent with this provision.
This Paragraph 20 shall survive termination of the Agreement except a
termination For Cause based upon the same facts as those based on which the
claim against the Employee is made for which he seeks indemnification.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the date first above written.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS
 
RESULTS OF OPERATIONS
 
  Fiscal 1997 Compared to Fiscal 1996
 
     Orders for the Company's products and services totaled $193.9 million in
fiscal 1997 as compared to $233.6 million in fiscal 1996. The decline in orders
in fiscal 1997 reflected the significant decline in demand for test equipment,
which began in the third quarter of fiscal 1996. However, the Company
experienced sequential improvement, each quarter, in orders since the fourth
quarter of fiscal 1996, as industry conditions gradually improved. With fiscal
1997 shipments at the same level as orders for the year, the Company's backlog
of $65.1 million at July 31, 1997 remained essentially unchanged from the prior
year-end.
 
     Net sales were $194.3 million in fiscal 1997 as compared to $266.5 million
in fiscal 1996, a decline of 27%. Sales of both the Company's mixed signal and
digital test systems were down significantly, while remaining at approximately
the same proportion of total sales year-to-year. Geographically, sales to
customers outside North America were 67% of total net sales in fiscal 1997 as
compared to 64% in fiscal 1996. While sales in all geographic regions were lower
year-to-year, the Company experienced a substantial improvement in its orders
from Japan in the fourth quarter of fiscal 1997.
 
                                        1
<PAGE>   2
 
     Excluding provisions for inventories, the gross profit margin was 32.1% of
net sales in fiscal 1997 as compared to 39.3% of net sales in fiscal 1996. An
inventory provision of $9.3 million in the first quarter of fiscal 1997 reduced
the gross profit margin by 4.8% of net sales for fiscal 1997. In fiscal 1996, an
inventory provision of $3.6 million in the fourth quarter reduced the gross
profit margin by 1.4% in fiscal 1996. In fiscal 1997, the gross profit margin
was adversely affected by the lower level of sales relative to fixed
manufacturing costs and relative to the cost of the Company's applications
assistance and customer support organizations. However, as a result of a
combination of increasing sales and a reduction in manufacturing costs, the
Company's gross profit margin improved each quarter during fiscal 1997.
 
     In the first quarter of fiscal 1997, the Company redirected its product
strategy to focus primarily on functionally complex devices known as
"systems-on-a-chip." The Company has undertaken a significant product
development program, which makes use of its digital and mixed signal test
capabilities, to introduce a new family of products designed to address this
emerging market. As a result, the Company restructured its Digital Products
Division management team in October 1996 and began emphasizing sales of its
Delta/STE mixed technology test system. The Company recorded an inventory
provision of $9.3 million in the first quarter for inventories related to
non-strategic products and a charge of $6.7 million for canceled non-strategic
development projects and related equipment, other costs resulting from the
change in product strategy and severance costs related to a workforce reduction.
During the first quarter of fiscal 1997, the Company eliminated 180 positions,
primarily in its manufacturing operations.
 
     Engineering and product development expenses were $23.4 million, or 12.0%
of net sales, in fiscal 1997 as compared to $22.9 million, or 8.6% of net sales,
in fiscal 1996. Engineering expenditures have remained at essentially the same
level year-to-year, which reflects the Company's commitment to maintaining its
investment in developing products required to fully test "system-on-a-chip"
devices. The Company expects to increase its engineering and product development
expenses by over 10% in fiscal 1998 over fiscal 1997.
 
     Selling, general and administrative expenses were $39.0 million, or 20.1%
of net sales, in fiscal 1997 as compared to $46.8 million, or 17.5% of net
sales, in fiscal 1996. The lower level of expenses is a result of a combination
of lower variable selling costs and variable compensation, reduced discretionary
spending, as well as a workforce reduction and the required use of vacation
during a holiday shutdown, which occurred in the first half of fiscal 1997.
 
     Interest expense was $2.4 million in fiscal 1997 as compared to $2.5
million in fiscal 1996. The slightly lower interest expense was due to the
reduction in long-term debt resulting from sinking fund payments. Interest
income was $2.9 million in fiscal 1997 and $2.8 million in fiscal 1996.
 
     The Company's tax provision in fiscal 1997 was $0.4 million as compared to
$1.4 million in fiscal 1996. The fiscal 1997 provision primarily reflects only
certain state and foreign provisions.
 
     In May 1997, to allow the Company to increase sales, marketing and support
activities in Japan, the Company increased its ownership in its
majority-controlled Japanese subsidiary from 50.5% to 67.0%. The Company's
Japanese subsidiary operated at a small loss during fiscal 1997.
 
     Excluding inventory and product line restructuring charges of $16.0 million
in the first quarter of fiscal 1997, the Company had net income of $0.1 million.
The loss for the year, including these charges, was $15.9 million, or $0.45 net
loss per share. On a quarterly basis, the Company improved its financial
performance each quarter during fiscal 1997, beginning with net income of $0.4
million, or $0.01 per share, in the second quarter and ending with net income of
$1.8 million, or $0.05 per share, in the fourth quarter.
 
     Until backlog levels increase substantially, the Company's ability to
maintain profitable operations in the near term will continue to depend on
obtaining the required level of shippable orders to meet its quarterly sales
objectives. The Company's results of operations would be adversely affected if
it were to experience lower than anticipated order levels, extended customer
delivery requirements or lower than anticipated margins due to changes in
product mix.

  Fiscal 1996 Compared to Fiscal 1995
 
     Orders of $233.6 million for the Company's products and services in fiscal
1996 were slightly lower than the fiscal 1995 level of $236.9 million. The
Company experienced strong industry demand during the first half of fiscal 1996.
However, industry conditions weakened during the Company's third fiscal quarter,
and demand for test equipment fell through the balance of the fiscal year.
Primarily as a result of these weak industry conditions, the Company's backlog
declined to $65.5 million at July 31, 1996, as compared to $98.4 million at July
31, 1995.
 
     Net sales were $266.5 million in fiscal 1996 as compared to $210.3 million
in fiscal 1995, an increase of 27%. Sales of the Company's mixed signal test
systems were 18% higher in fiscal 1996 as compared to fiscal 1995 and sales of
digital test systems in fiscal 1996 increased 55% over fiscal 1995. The increase
in sales for both product lines in fiscal 1996 was primarily a result of strong
semiconductor industry conditions during the first half of fiscal 1996 together
with the large backlog of unshipped orders at the beginning of the fiscal year.
Sales to customers outside North America represented 64% of total sales in
fiscal 1996 as compared to 66% of total sales in fiscal 1995.
 
     The gross profit margin was 37.9% of net sales in fiscal 1996 as compared
to 35.0% of net sales in fiscal 1995. The improvement in the gross profit margin
in fiscal 1996 was a result of proportionately lower fixed manufacturing costs
on the higher shipment levels, savings from product cost reduction programs and
higher average selling prices, particularly on the Synchro Series. These
improvements were partially offset by a provision of $3.6 million for excess and
obsolete inventories in the fourth quarter of fiscal 1996. This provision was
largely a result of obsolete components and parts due to product redesigns
associated with the Company's Delta Series test systems.
 
     Engineering and product development expenses were $22.9 million, or 8.6% of
net sales, in fiscal 1996 as compared to $19.8 million, or 9.4% of net sales, in
fiscal 1995. The increase in engineering and product development expenses
reflected additional resources the Company invested in product development
programs relating to its Synchro, Delta and iPTest product lines.
 
     Selling, general and administrative expenses were $46.8 million, or 17.5%
of net sales, in fiscal 1996 as compared to $39.0 million, or 18.5% of net
sales, in fiscal 1995. The increase in expenses in fiscal 1996 included the
introduction of an employee profit sharing bonus plan and matching of
contributions to the Company's 401(k) plan along with higher travel expenses and
sales commissions on the higher level of sales.
 
     Net interest income was $0.3 million in fiscal 1996 as compared to net
interest expense of $3.8 million in fiscal 1995. Interest expense of $2.5
million in fiscal 1996 was $1.7 million lower than fiscal 1995 primarily as a
result of the conversion of the Company's 131/2 % Convertible Subordinated
Debentures into 2,241,000 shares of the Company's common stock in July 1995. In
fiscal 1996, the Company generated $2.8 million in interest income, $2.4 million
more than in fiscal 1995, primarily as a result of the investment of the $55.8
million in proceeds received in October 1995 from a public offering of the
Company's common stock.
 
     The Company's tax provision in fiscal 1996 was $1.4 million, or 4.4% of
pre-tax income. The Company fully used its U.S. federal net operating loss
carryforward, and a portion of its U.S. federal tax credit carryforward during
fiscal 1996. As a result, the tax provision represents a minimal level of U.S.
federal, state and foreign income taxes. In fiscal 1995, the tax provision of
$0.4 million represented only certain state and foreign tax liabilities.
 
     The Company's Japanese subsidiary's results of operations were
approximately break-even in fiscal 1996 and 1995. As a result, the minority
partner's share of the Company's Japanese subsidiary's results was
insignificant.
 
     The Company had net income of $30.3 million, or $0.82 per share, in fiscal
1996 as compared to $10.7 million, or $0.36 per share, in fiscal 1995. The 183%
increase in net income year-to-year was largely a result of the combination of
higher sales levels, an improvement in the gross profit margin as a percentage
of net sales, the reduction in operating expenses as a percentage of net sales
and added interest income.

  Liquidity and Capital Resources
 
     Cash and short-term investments were $67.8 million at July 31, 1997 as
compared to $76.0 million at July 31, 1996. The decrease in cash and short-term
investments of $8.2 million was a result of $10.2 million of net cash provided
by operating activities, $16.1 million of net cash used for property and
equipment additions and $2.0 million of net cash used in financing activities.
 
     The Company had positive net cash flow of $10.2 million from operating
activities in fiscal 1997. The reduction in accounts receivable of $4.8 million
reflects the lower level of sales in fiscal 1997 as compared to fiscal 1996.
Inventories declined $11.5 million in fiscal 1997, largely as a result of the
inventory provision in the first quarter of fiscal 1997 of $9.3 million.
Accounts payable declined $4.5 million as a result of the reduction in inventory
purchases required to support the lower level of sales in fiscal 1997. Accrued
expenses and restructuring costs increased $3.0 million during fiscal 1997 as a
result of the provision for product line restructuring in the first quarter of
$6.7 million. At July 31, 1997, the Company had $2.2 million remaining in its
restructuring provision to cover the future costs resulting from its change in
product strategy.
 
     Property and equipment additions of $16.1 million during fiscal 1997 were
mostly for product development and customer support activities. In addition, the
Company purchased, and is in the process of installing, a new management
information system. Non-cash depreciation charges were $11.0 million in fiscal
1997. The Company expects that expenditures for property and equipment will be
lower in fiscal 1998 than the level of expenditures in fiscal 1997.
 
     The Company's Japanese subsidiary had bank borrowings of $6.5 million at
July 31, 1997 as compared to $8.3 million at July 31, 1996. During fiscal 1997,
the Company's long-term subordinated note was reduced by $4.0 million as a
result of regularly scheduled payments.
 
     In June 1997, the Company obtained a $25.0 million domestic credit
facility. The facility includes a $20.0 million working capital line and a $5.0
million equipment lease line. At July 31, 1997, there were no borrowings
outstanding under the working capital line and $1.8 million in operating
equipment leases had been originated under the equipment lease line.
 
     The Company purchased 0.7 million shares of its common stock, for $3.4
million, in the first half of fiscal 1997 under its previously announced stock
repurchase program.
 
     In July 1997, Ando Electric Co., Ltd. purchased 1.0 million shares of
common stock, for $2.3 million, pursuant to the exercise of the remaining shares
under a warrant previously issued by the Company.
 
     Management believes that the Company has sufficient cash resources to meet
its fiscal 1998 cash requirements. These resources include cash balances of
$67.8 million at July 31, 1997, together with the borrowing availability under
its domestic working capital and equipment lease line and future cash flows from
operations.
 
BUSINESS RISKS
 
     The Company in this report makes, and may from time to time elsewhere make,
disclosures which contain forward-looking statements within the meaning of the
Private Securities Litigation Reform Act of 1995. Such disclosures in this
report include, without limitation, statements regarding the development,
introduction, acceptance, and market for Fusion, the Company's belief, under
"Results of Operations-Fiscal 1997 Compared to Fiscal 1996," as to anticipated
increases in engineering and product development expenses and the Company's
belief, under "Liquidity And Capital Resources," as to the adequacy of its cash
resources and the level of expenditures for property and equipment. Such
forward-looking statements involve risks and uncertainties including, but not
limited to, the following important factors that could cause actual results to
differ materially from those in the forward-looking statement:
 
  Fluctuations in Sales and Operating Results
 
     Given the relatively large selling prices of the Company's test systems,
sales of a limited number of test systems account for a substantial portion of
sales in any particular fiscal quarter and a small number of
 
                                        4
<PAGE>   5
 
transactions could therefore have a significant impact on sales and gross
margins for that fiscal quarter. The Company's sales and operating results have
fluctuated and could in the future fluctuate significantly from period to
period, including from one quarterly period to another, due to a combination of
factors, including the cyclical demand of the semiconductor industry, order
cancellations or rescheduling by customers, the large selling prices of the
Company's test systems (which typically result in a long selling process),
competitive pricing pressures and the mix between and configuration of test
systems sold in a particular period. The impact of these and other factors on
the Company's sales and operating results in any future period cannot be
forecast with accuracy. In addition, the need for continued investment in
research and development, for capital equipment requirements and for extensive
worldwide customer support capability results in significant fixed costs which
would be difficult to reduce in the event that the Company does not meet its
sales objectives.
 
  Importance of New Product Introductions
 
     The semiconductor test equipment (STE) market is subject to rapid
technological change and new product introductions, as well as advancing
industry standards. The development of increasingly complex semiconductors and
the utilization of semiconductors in a broader spectrum of products has driven
the need for more advanced test systems to test such devices at an acceptable
cost. The Company's ability to remain competitive in the mixed signal and
system-on-a-chip integrated circuit (IC) and discrete component markets will
depend upon its ability to successfully enhance existing test systems, develop
new generations of test systems, such as its new Fusion platform, and to
introduce these new products on a timely and cost-effective basis. The Company
also has to manufacture its products in volume at a competitive price and on a
timely basis to enable customers to integrate them into their operations as they
begin to produce their next generation of semiconductors. The Company's failure
to have a competitive test system available when required by a semiconductor
manufacturer would make it substantially more difficult for the Company to sell
test systems to that manufacturer for a number of years. The Company has in the
past experienced delays in introducing certain of its products and enhancements,
and there can be no assurance that it will not encounter technical or other
difficulties that could in the future delay the introduction of new products or
enhancements. If new products have reliability or functionality problems, then
reduced, canceled or rescheduled orders, higher manufacturing costs, delays in
collecting accounts receivable and additional warranty expense may result, which
could reduce gross margins on new product sales and otherwise materially affect
the Company's business and results of operations. The Company's Fusion product
is subject to the risks associated with new product introductions, including the
risk that delays in development, reliability or functionality problems could
increase expenses and reduce gross margins on new product sales. Furthermore,
announcements by the Company or its competitors of new products could cause
customers to defer or forego purchases of the Company's existing products, which
would also adversely affect the Company's business and results of operations.
There can be no assurance that the Company will be successful in the
introduction and volume manufacture of its new products, that such introduction
will coincide with the development by semiconductor manufacturers of their next
generation semiconductors or that such products will satisfy customer needs or
achieve market acceptance. The failure to do so could materially adversely
affect the Company's business and results of operations.
 
  Cyclicality of Semiconductor Industry
 
     The Company's business is largely dependent upon the capital expenditures
of semiconductor manufacturers. The semiconductor industry is highly cyclical
and has historically experienced recurring periods of oversupply, which often
have had a severely detrimental effect on such industry's demand for test
equipment and could cause cancellations, rescheduling or reductions of customer
orders. No assurance can be given that the Company's business and results of
operations will not be materially adversely affected if the current downturn
continues for a prolonged period or if downturns or changes in any particular
market segments of the semiconductor industry occur in the future, especially if
all of the market segments in which the Company participates experience
downturns at the same time.
 
                                        5

  Highly Competitive Industry
 
     The STE industry is highly competitive in all areas of the world. Most of
the Company's major competitors have substantially greater financial resources
and some have more extensive engineering, manufacturing, marketing and customer
support capabilities than the Company. The Company expects its competitors to
continue to improve the performance of their current products and to introduce
new products with improved price and performance characteristics. The Company
principally competes on the basis of performance, cost of test, reliability,
customer service, applications support, price and ability to deliver its
products on a timely basis. New product introductions by the Company's
competitors could cause a decline in sales or loss of market acceptance of the
Company's existing products and could prevent the successful introduction of the
Company's new products. In addition, increased competitive pressure could lead
to intensified price-based competition, resulting in lower prices and adversely
affecting the Company's business and results of operations. The Company believes
that to remain competitive it will require significant financial resources for
investment in new product development and for the maintenance of customer
support centers worldwide. There can be no assurance that the Company will be
able to compete successfully in the future.
 
  Customer Concentration
 
     The loss of a major customer or reduction in, or rescheduling or
cancellation of, orders by major customers, including reductions, cancellations
or rescheduling due to market or competitive conditions in the semiconductor
industry, has had in the past and could have in the future an adverse effect on
the Company's business and results of operations. In addition, the Company's
ability to increase its sales will depend in part upon its ability to obtain
orders from new customers. The loss of one or more of its top ten customers
could have a material adverse effect on the Company's business and results of
operations.
 
  Dependence upon Key Personnel
 
     The Company's success is dependent upon certain key management and
technical personnel. There is intense competition for a limited number of
qualified employees among companies in the semiconductor test equipment
industry, and the loss of certain of the Company's employees or an inability to
attract and motivate highly skilled employees could adversely affect its
business.
 
  Dependence upon Key Suppliers
 
     Most of the components for the Company's products are available from a
number of different suppliers; however, certain components are purchased from a
single supplier. Any disruption or termination of supply of components,
particularly single source components, could have an adverse effect on the
Company's business and results of operations.
 
  Acquisitions
 
     The Company from time to time may acquire technologies, product lines or
businesses that are complementary to those of the Company. Although the Company
believes that integration of acquired technologies, product lines and businesses
will result in long-term growth and profitability, there can be no assurance
that the Company will be able to successfully negotiate, finance or integrate
such acquired technologies, product lines or businesses. Furthermore, the
integration of an acquired company or business may cause a diversion of
management time and resources. There can be no assurance that a given
acquisition, if consummated, would not materially adversely affect the Company.
 
  Proprietary Rights
 
     The Company's future success depends in part upon its proprietary
technology. Although the Company attempts to protect its proprietary technology
through a combination of contract provisions, trade secrets, copyrights and
patents, it believes that its future success depends more upon its engineering,
manufacturing, marketing and service skills. There can be no assurance that the
steps taken by the Company to protect its proprietary rights will be adequate to
prevent misappropriation of its technology or the independent development by
others of similar technology. Although there are no pending actions against the
Company regarding any patents, no assurance can be given that infringement
claims by third parties will not have a material adverse effect on the Company's
business and results of operations.

                                LTX CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1.  THE COMPANY
 
     LTX Corporation (the Company) designs, manufactures, and markets automatic
test equipment for the semiconductor industry that is used to test digital,
linear, and mixed signal (a combination of digital and linear) integrated
circuits (ICs) and discrete semiconductor components. The Company is
headquartered in Westwood, Massachusetts, has development and manufacturing
facilities in Westwood, Massachusetts, and San Jose, California, and worldwide
sales and service facilities to support its customer base.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     The consolidated financial statements include the accounts of the Company
and its wholly owned domestic subsidiaries and wholly owned and majority-owned
foreign subsidiaries. All significant intercompany transactions and balances
have been eliminated in consolidation.
 
  Preparation of Financial Statements
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts 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. Operating results in the future could vary from the amounts derived
from management's estimates and assumptions.
 
  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, which have not been significant in the past
three fiscal years, are included in the results of operations.
 
  Revenue Recognition
 
     Revenue 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.
 
  Engineering and Product Development Costs
 
     The Company expenses all engineering, research and development costs as
incurred. Expenses subject to capitalization in accordance with the Statement of
Financial Accounting Standards No. 86, "Accounting for the Costs of Computer
Software To Be Sold, Leased or Otherwise Marketed," relating to certain software
development costs, were insignificant.
 
  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 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
 
                                       11

the past since it reinvested those earnings. At July 31, 1997, most of the
Company's foreign subsidiaries had accumulated deficits.
 
  Net Income (Loss) per Share
 
     Primary and fully diluted net income per share are based on the weighted
average number of shares of common stock and common stock equivalents (shares
issuable under stock option plans and warrants) outstanding. None of the
Company's convertible subordinated debentures are common stock equivalents. Net
loss per share is based on the weighted average number of shares of common stock
outstanding only, as the inclusion of common stock equivalents would be
anti-dilutive.
 
  Financial Instruments
 
     Cash and Short-Term Investments
 
     The Company considers all highly liquid investments that are readily
convertible to cash and that have original maturity dates of three months or
less to be cash equivalents. Cash equivalents consist primarily of repurchase
agreements and commercial paper. Effective August 1, 1995, the Company adopted
Statement of Financial Accounting Standards No. 115, "Accounting for Certain
Investments in Debt and Equity Securities" (FAS 115). In accordance with FAS
115, investments in debt securities are classified as trading,
available-for-sale or held-to-maturity. Investments are classified as
held-to-maturity when the Company has the positive intent and ability to hold
those securities to maturity. Held-to-maturity securities are stated at
amortized cost with premiums and discounts amortized to interest income over the
life of the investment.
 
     The Company has no short-term investments as of July 31, 1997. The fair
market value of cash equivalents and short-term investments is substantially
equal to the amortized cost, due to the short period of time to maturity, which
is less than one year.
 
     Fair Value
 
     Statement of Financial Accounting Standards No. 107, "Disclosures About
Fair Value of Financial Instruments," which was adopted by the Company effective
August 1, 1995, requires that disclosure be made of estimates of the fair value
of financial instruments. The fair value of the Company's notes payable and
long-term liabilities is estimated based on quoted market prices for the same or
similar issues or on current rates offered to the Company for debt of the same
remaining maturities. At July 31, 1997 and 1996, the carrying value of
$6,471,000 and $8,252,000, respectively, for notes payable and $18,593,000 and
$20,788,000, respectively, for long-term liabilities, including current portion,
approximates fair value. At July 31, 1997 and 1996, the Company's 7 1/4%
Convertible Subordinated Debentures due 2011 had a carrying value of $7,308,000
and the estimated fair value was approximately $6,200,000 and $5,800,000,
respectively. For all other balance sheet financial instruments, the carrying
amount approximates fair value.
 
     Concentration of Credit Risk
 
     Financial instruments that potentially subject the Company to
concentrations of credit risk consist principally of investments in cash
equivalents, short-term investments and trade receivables. The Company places
its investments with high-quality financial institutions, limits the amount of
credit exposure to any one institution and has established investment guidelines
relative to diversification and maturities designed to maintain safety and
liquidity. The Company's trade receivables result primarily from sales to
semiconductor manufacturers located in North America, Japan, the Pacific Rim and
Europe. Receivables are from major corporations or are supported by letters of
credit. The Company maintains reserves for potential credit losses and such
losses have been immaterial.

     Recent Accounting Pronouncements
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings Per Share" (FAS 128), which
is effective for periods ending after December 15, 1997. FAS 128 requires the
presentation of basic earnings per share (EPS) and diluted EPS. Basic EPS
replaces the primary EPS calculation required under APB Opinion No. 15. Basic
EPS excludes dilution and is calculated using the weighted average of common
shares outstanding for the period. Diluted EPS is computed similarly to fully
diluted EPS pursuant to APB Opinion No. 15. The pro forma effect of this
accounting change on the July 31, 1997 and July 31, 1996 previously reported EPS
data is as follows:

     The Company's Japanese subsidiary had borrowings outstanding of $6,471,000
at July 31, 1997 under demand bank lines of credit. Borrowings of $5,462,000, at
the local prime rate plus 1/4%, are guaranteed by the Company's minority partner
in Japan, and borrowings of $1,009,000, at the local prime plus 3/4%, under a
$1,681,000 demand bank line, are guaranteed by the Company. At July 31, 1996,
the Company's Japanese subsidiary had borrowings outstanding of $8,252,000 under

     In June 1997, the Company expanded its line of credit with its domestic
banks. The new agreement is comprised of a $20,000,000 unsecured working capital
line and a $5,000,000 equipment lease line. The working capital line matures in
July 1998 and borrowings are at the agent bank's prime rate. Borrowings under
the equipment lease line are available through July 1998 and are secured by the
leased equipment, with repayments scheduled over a maximum three-year period.
Borrowings availability under the working capital line are on a formula basis.
The working capital line has financial covenants that largely relate to results
of operations and minimum levels of liquidity. At July 31, 1997, there were no
borrowings outstanding under the working capital line, and $1,767,000 in
operating leases had been originated under the equipment lease line.

7.  STOCKHOLDERS' EQUITY
 
  Stock Repurchase Program
 
     In June 1996, the Board of Directors authorized a stock repurchase program
under which the Company could acquire up to 3,500,000 shares of its common stock
over a 12-month period. In fiscal 1997, the Company purchased 747,500 shares, to
be held in treasury, at a cost of $3,356,000 under this program. In fiscal 1996,
the Company purchased 200,000 shares at a cost of $1,005,000.
 
  Warrants
 
     In July 1994, in connection with the issuance of a subordinated note, the
Company issued a warrant to purchase up to 2,000,000 shares of common stock at
the then fair market value of $2.31 per share during the term of the note (see
Note 4). In June 1996, 1,000,000 shares of common stock were exercised under
this warrant. In July 1997, the remaining 1,000,000 shares under this warrant
were exercised.
 
  Rights Agreement
 
     The Board of Directors of the Company adopted a Rights Agreement, dated as
of May 11, 1989, between the Company and The First National Bank of Boston, as
rights agent, and in connection therewith, distributed one common share purchase
right for each outstanding share of common stock. The rights will become
exercisable only if a person or group acquires 20% or more of the Company's
common stock or announces a tender offer that would result in ownership of 30%
or more of the common stock. Initially, each right will entitle a stockholder to
buy one share of common stock of the Company at a purchase price of $30.00 per
share, subject to significant adjustment depending on the occurrence thereafter
of certain events. Before any person or group has acquired 20% or more of the
common stock of the Company, the rights are redeemable by the Board of Directors
at $0.01 per right. The rights will expire on May 11, 1999 unless redeemed by
the Company prior to that date.

8.  EMPLOYEE BENEFIT PLANS
 
  Stock Option Plans
 
     The Company has two stock option plans: the 1990 Stock Option Plan (1990
Plan) and the 1995 LTX (Europe) Ltd. Approved Stock Option Plan (U.K. Plan).
 
     The 1990 Plan and the U.K. Plan provide for the granting of options to
employees to purchase shares of common stock at not less than 100% of the fair
market value on the date of grant. The 1990 Plan also provides for the granting
of options to an employee, director or consultant of the Company or its
subsidiaries to purchase shares of common stock at prices to be determined by
the Board of Directors. Compensation expense relating to shares granted under
this plan at less than fair market value has been charged to operations over the
applicable vesting period. Options under both plans are exercisable over vesting
periods, which are typically three years beginning one year from the date of
grant. In December 1995, the stockholders of the Company approved an increase to
the number of shares of common stock that may be granted under the 1990 Plan,
through October 2000, from 2,700,000 shares to 3,700,000 shares. At July 31,
1997, 588,846 shares were subject to future grant under the 1990 Plan and 48,000
shares were subject to future grant under the U.K. Plan.
 
  Compensation Expense
 
     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (FAS 123), which is effective for the Company's fiscal year ended
July 31, 1997. FAS 123 requires employee stock-based compensation to be either
recorded or disclosed at its fair value. As permitted by FAS 123, the Company
has elected to continue to account for employee stock-based compensation under
Accounting Principles Board Opinion No. 25. Had compensation costs for awards in
fiscal 1997 and 1996 under the Company's stock-based compensation plans been
determined based on the fair value at the grant dates consistent with the method
set forth under FAS 123, the effect on the Company's net income (loss) and net
income (loss) per share would have been as follows:
 
<TABLE>
<CAPTION>
                                                                YEAR ENDED JULY 31,
                                                               ---------------------

          <S>                                                  <C>          <C>
          Net income (loss):
               As reported...................................  $(15,909)    $ 30,270
               Pro forma.....................................  $(17,535)    $ 29,985
          Net income (loss) per share:
            Primary
               As reported...................................  $  (0.45)    $   0.82
               Pro forma.....................................  $  (0.49)    $   0.82
            Fully Diluted
               As reported...................................  $  (0.45)    $   0.82
               Pro forma.....................................  $  (0.49)    $   0.82
</TABLE>
 
     Since the method prescribed by FAS 123 has not been applied to options
granted prior to August 1, 1995, the resulting pro forma compensation expense
may not be representative of the amount to be expected in future years. Pro
forma compensation expense for options granted is reflected over the vesting
period; therefore, future pro forma compensation expense may be greater as
additional options are granted.

     The fair value of each option grant is estimated on the grant date using
the Black-Scholes option-pricing model with the following weighted average
assumptions:
 
<TABLE>
<CAPTION>
                                                                 YEAR ENDED JULY 31,

                                                              -----------    -----------
          <S>                                                 <C>            <C>
          Volatility........................................          83%            83%
          Risk-free interest rate...........................       5.875%         5.875%
          Expected life of options..........................   5.02 years     5.02 years
</TABLE>
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option-pricing models require the input
of highly subjective assumptions. Because the Company's employee stock options
have characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of its employee
stock options.

     Employees' Stock Purchase Plan
 
     In December 1993, the stockholders of the Company approved the adoption of

purchase of common stock of the Company up to $25,000 of fair market value of
the stock per calendar year. The plan limits the number of shares which can be
issued for any semi-annual plan period to 150,000 shares and, over the term of
the plan, the Company may issue up to 1,200,000 shares. At July 31, 1997, 76,475
shares were available for future issuance under this plan.
 
     Other Compensation Plans
 
     In fiscal 1996, the Company established a Profit Sharing Bonus Plan,
wherein a percentage of pretax profits are distributed semi-annually to all
employees. In addition, the Company has a 401(k) Growth and Investment Program.
Eligible employees may make voluntary contributions to this plan through a
salary reduction contract up to the statutory limit or 15% of their annual
compensation. In fiscal 1996, the Company began matching employees' voluntary
contributions to the plan, up to certain prescribed limits. These Company
contributions vest at a rate of 20% per year. The total charge to expense under
these plans was $1,035,000 in fiscal 1997 and $2,006,000 in fiscal 1996.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

 
To the Board of Directors and Stockholders of LTX Corporation:
 
     We have audited the accompanying consolidated balance sheet of LTX
Corporation and subsidiaries as of July 31, 1997 and 1996, and the related
consolidated statements of operations, stockholders' equity and cash flows for
each of the three years in the period ended July 31, 1997. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of LTX Corporation and
subsidiaries as of July 31, 1997 and 1996, and the results of their operations
and their cash flows for each of the three years in the period ended July 31,
1997, in conformity with generally accepted accounting principles.
