                               PROSPECTUS SUMMARY
 
  The following summary is qualified in its entirety by the more detailed
information and the Consolidated Financial Statements, including the Notes
thereto, appearing elsewhere or incorporated by reference in this Prospectus.
Except as otherwise noted herein or as presented in the Consolidated Financial
Statements, all information in this Prospectus assumes that the Underwriters'
over-allotment option will not be exercised and assumes for purposes of
calculating the number of shares issuable on exercise of certain warrants held
by the Selling Stockholders that such warrants will be exercised on a cashless
net issuance basis prior to the closing of the Offering at an assumed fair
market value of $33.25 per share of Common Stock. See "Principal and Selling
Stockholders." The Company's fiscal year ends on June 30 of the relevant year.
 
                                  THE COMPANY
 
  LeCroy Corporation develops, manufactures and sells signal analyzers,
principally high-performance digital oscilloscopes and related products.
Digital oscilloscopes capture electronic signals, convert them to digital form
and perform sophisticated measurements and analyses. The Company's digital
oscilloscope products are used by design engineers and researchers in a broad
range of industries, including electronics, computers and communications.
 
  High-performance digital oscilloscopes have become an important enabling
technology as a result of the general shift in technology toward high-speed
digital electronics and faster and more complex electronic signals. The
analysis of such signals requires digital oscilloscopes with high sample rates
and long record lengths, two key performance measurements in the digital
oscilloscope market. The Company believes that certain models in its 9300
series and LC series of high-performance digital oscilloscopes offer the
highest sampling rate, and others the longest record length, available to date.
 
  In 1985, the Company introduced its first digital oscilloscope product.
Commencing in fiscal 1994, the Company began to focus its digital oscilloscope
product offerings on the high-end market, which has resulted in a significant
increase in revenues. At that time, the Company began to concentrate its
digital oscilloscope product offerings on a single high-performance product
family, its 9300 series. In fiscal 1997, the Company expanded its high-end
market product offerings with a second family of products, the LC series of
digital oscilloscopes. The Company's total revenues were $63.8 million, $82.3
million and $101.5 million for the fiscal years ended June 30, 1994, 1995 and
1996, respectively, and $55.2 million for the six months ended December 31,
1996. Sales of digital oscilloscopes and related products grew from
approximately 75% of the Company's total revenues for fiscal year 1994 to
approximately 89% of the Company's total revenues for the six months ended
December 31, 1996. Further, the focus on the Company's high-performance product
families, together with management's continued emphasis on operational
improvements, have resulted in efficiency gains in product development,
manufacturing, marketing, sales and service. These factors, together with the
increase in revenues, have contributed to an increase in operating margin from
4.8% for fiscal 1994 to 8.5% for fiscal 1996 and 9.8% for the six months ended
December 31, 1996.
 
  The Company's original digital oscilloscope technology was derived from its
historical efforts in developing products for high energy physics ("HEP")
research. Since its founding in 1964, the Company has designed and manufactured
instrumentation and signal analyzers for a number of leading HEP research
laboratories. The Company's signal analyzers were used in Nobel Prize winning
experiments at CERN (Centre Europeen pour la Recherche Nucleaire) near Geneva,
Switzerland and the Brookhaven National Laboratory in Upton, New York.
 
                                       3
<PAGE>
 
Sales of HEP products have been declining and accounted for approximately 21%,
15% and 11% of the Company's total revenues for the fiscal years ended June 30,
1994, 1995 and 1996, respectively, and 7% of the Company's total revenues for
the six months ended December 31, 1996. The Company expects the decline in HEP
revenues to continue. As a consequence, in January 1997 the Company adopted a
strategic business plan to reduce costs and improve asset utilization in its
HEP business. Under this plan, the Company is redirecting its engineering
resources within this business unit to focus principally on the development and
sale of signal analysis chip sets and subsystems for HEP applications as well
as new commercial applications. In connection with the plan, the Company
expects to take a series of reorganization actions resulting in write-downs,
principally for inventory and other asset revaluations, and employee severance.
The restructuring plan is expected to be completed by the end of December 1997
and result in a charge to fiscal 1997 third quarter results of an estimated
$3.9 million ($2.5 million after taxes).
 
  The Company's first business objective is to become a leading supplier of
high-performance digital oscilloscopes. According to Prime Data, Inc. ("Prime
Data"), total digital oscilloscope sales, excluding handhelds, grew from $586.5
million in 1992 to $755.0 million in 1996. The Company's second business
objective is to participate in broader markets by the use, directly and through
licensing and other arrangements with other manufacturers, of the Company's
core acquisition technology in dedicated signal analyzers. The Company believes
that market opportunities for such products are very broad, including
applications in data storage, networking and communications. The Company has
entered into an agreement to sell certain proprietary chip sets to Guzik
Technical Enterprises for use in dedicated instruments for data storage
devices, such as disk drives, and their components. The Company has also
entered into an agreement with Fluke Corporation under which the Company has
licensed Fluke to use LeCroy technology in certain handheld scopemeters and
low-end digital oscilloscopes. See "Business--Products and Services."
 
  In addition to these agreements, the Company is using its signal analysis
technology in a new LAN monitor product currently under development. This
product would analyze electronic signals in communications networks in order to
provide better monitoring and failure-diagnosis capabilities than can be
achieved using existing products.
 
  The Company operates internationally with manufacturing facilities in Geneva,
Switzerland and Chestnut Ridge, New York. The Company maintains a direct sales
force in the United States, Europe and Japan and uses manufacturers'
representatives as an extension of its direct selling efforts.
 
  The Company was founded and incorporated in the State of New York in 1964 and
reincorporated in the State of Delaware in 1995. The Company's principal
executive offices are located at 700 Chestnut Ridge Road, Chestnut Ridge, New
York 10977, and its phone number at that location is (914) 425-2000.

                                 RISK FACTORS
 
  An investment in the shares of Common Stock offered hereby involves a high
degree of risk. Prospective investors should consider carefully the following
risk factors, in addition to the other information set forth in this
Prospectus, in connection with an investment in the Common Stock offered
hereby.
 
  This Prospectus contains statements that constitute "forward-looking
statements" within the meaning of Section 27A of the Securities Act of 1933,
as amended (the "Securities Act"), and Section 21E of the Securities Exchange
Act of 1934, as amended (the "Exchange Act"). Those statements appear in a
number of places in this Prospectus and include statements regarding the
intent, belief or current expectations of the Company or its directors or
officers with respect to, among others things: (i) the licensing of the
Company's core acquisition technology for use in dedicated signal analyzers;
(ii) the targeting of additional high growth industries that require solution-
focused oscilloscopes; (iii) trends affecting the Company's financial
condition or results of operation, including the effect of foreign currency
exchange rates on revenues; (iv) the Company's business and growth strategies;
and (v) the results of the HEP restructuring plan. Prospective investors are
cautioned that any such forward-looking statements are not guarantees of
future performance and involve risks and uncertainties, and that actual
results may differ materially from those projected, expressed or implied, in
the forward-looking statements as a result of various factors. The
accompanying information contained in this Prospectus, including without
limitation the information set forth under the headings "Risk Factors,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business," identifies important factors that could cause such
differences. Such forward-looking statements speak only as of the date of this
Prospectus and the Company cautions potential investors not to place undue
reliance on such statements.
 
  COMPETITION. The market for signal analyzers such as the Company's digital
oscilloscopes is highly competitive. The Company's principal competitors in
this market are Tektronix, Inc., Hewlett-Packard Company and Fluke
Corporation, some of which have substantially greater sales and marketing,
development and financial resources than the Company and some of which have a
greater market share than the Company.
 
  The Company believes that the principal bases of competition in the signal
analyzer market are a product's performance (bandwidth, sample rate, record
length and processing power), its price and quality, the vendor's name
recognition and reputation, color display, product availability and the
availability and quality of post-sale support. The rapidly evolving nature of
the markets in which the Company competes may attract new entrants as they
perceive opportunities, and the Company's competitors may foresee the course
of market developments more accurately than the Company. In addition, the
Company's competitors may develop products that are superior to the Company's
products or may adapt more quickly than the Company to new technologies or
evolving customer requirements. The Company expects competition to increase
significantly in the future from existing competitors and other companies that
may enter the Company's existing or future markets. There can be no assurance
that the Company will be able to compete successfully with its existing
competitors or with new competitors. Failure to compete successfully could
adversely affect the Company's business, results of operations and financial
condition. See "Business--Industry Background" and "--Competition."
 
  TECHNOLOGICAL CHANGE; RISKS OF PRODUCT OBSOLESCENCE AND FAILURE TO DEVELOP
NEW PRODUCTS. The market for the Company's products is characterized by
rapidly changing technology and frequent new product introductions
particularly by the Company's principal competitors. See "Business--
Competition." The Company's success will depend, in part, upon its continued
ability to provide products with the advanced technological qualities desired
by its customers, to enhance and expand its existing product offerings and to
develop in a timely manner new products that achieve market acceptance. Any
failure or delay in accomplishing these goals could have a material adverse
effect on the Company's business, results of operations and financial
condition. In addition, current competitors or new market entrants may develop
new products with features that could adversely affect the competitive
position of the Company's products. Further, no assurance can be given that
the Company will be able to leverage its core technology into new product
markets. See "Business--Strategy."
 
                                       7

  FLUCTUATIONS IN REVENUES AND RESULTS OF OPERATIONS. The growth experienced
by the Company in its fiscal years ended June 30, 1995 and 1996 and the six
months ended December 31, 1996 is not necessarily indicative of future growth.
There can be no assurance that the Company's revenues will continue to
increase or that it will continue to be profitable. The Company's annual and
quarterly operating results may fluctuate due to factors such as the timing of
new product introductions by the Company and its competitors, market
acceptance of new or enhanced versions of the Company's products, changes in
the product mix of sales, changes in the relative proportions of sales
denominated in currencies other than United States dollars, changes in the
relative proportions of sales among distribution channels, changes in
manufacturing costs or other expenses, competitive pricing pressures, the gain
or loss of significant customers or distribution channels, increased research
and development expenses and general economic conditions. In addition, it is
possible that in some future periods, the Company's results of operations,
including gross margins, will be below the expectations of public market
analysts and investors. In any such event, the market price of the Common
Stock could be materially and adversely affected. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
  INTERNATIONAL OPERATIONS AND FOREIGN CURRENCY EXCHANGE RISKS. The Company
has manufacturing facilities in both the United States and Switzerland,
purchases parts, components and sub-assemblies from suppliers around the world
in a variety of currencies and sells its products around the world in a
variety of currencies. As a consequence, the Company is exposed to risks from
fluctuations in foreign currency exchange rates with respect to a number of
currencies, changes in government policies and legal and regulatory
requirements, political instability, transportation delays and the imposition
of tariffs and export controls.
 
  Among the more significant potential risks to the Company of relative
fluctuations in foreign exchange rates is the relationship among and between
the United States dollar, Swiss franc and Japanese yen, and, to a lesser
extent, the German deutschemark, British pound, French franc and Italian lira.
During the fiscal year ended June 30, 1996, approximately half of the
Company's revenues and half of its costs and expenses were denominated in
currencies other than the United States dollar, the Company's financial
reporting currency. Local currency expenses resulting from manufacturing and
the worldwide sourcing of parts, components and sub-assemblies are not
generally offset by related local currency revenues, if any. The Company does
not attempt to reduce its foreign currency exchange risks by entering into
foreign currency management programs or hedging transactions and has no plans
to do so in the near term. As a consequence, there can be no assurance that
the Company's results of operations will not be adversely affected by
fluctuations in foreign currency exchange rates in the future, as a result of
mismatches between local currency revenues and expenses, the translation of
foreign currencies into the United States dollar, or otherwise. Moreover,
fluctuations in exchange rates could affect demand for the Company's products.
Based on exchange rates as of the date of this Prospectus, the Company expects
that its revenues for the third quarter of fiscal 1997 will continue to be
adversely impacted by the strength of the U.S. dollar. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
  CERTAIN SINGLE-SOURCE SUPPLIERS; DIFFICULTY IN DEVELOPING ALTERNATIVE
SOURCES OF SUPPLY; POSSIBLE INCREASES IN COSTS OF MATERIALS. The Company
obtains certain parts, components and sub-assemblies from single sources. This
has particularly been the case for several key integrated circuits made by
certain single-source suppliers (Motorola, Philips, TRW and LSI Logic). The
Company has generally been able to obtain adequate supplies of components in a
timely manner from current vendors. The Company believes that, for the printed
circuit board assemblies and integrated circuits in particular, alternative
sources of supply would be difficult to develop. A reduction or interruption
of supply of these components could result in delays or reductions in product
shipments that could have a material adverse effect on the Company's business,
results of operations and financial condition and could damage its
relationships with customers. The Company may also be subject to cost
increases for such parts, components and sub-assemblies, which could have a
material adverse effect on its business, results of operations and financial
condition. See "Business--Manufacturing and Supplies."
 
                                       8

  POTENTIAL INABILITY TO MANAGE FUTURE GROWTH AND CHANGING BUSINESS. The
Company's revenues from sales of digital oscilloscopes and related products
grew significantly in the fiscal year ended June 30, 1996, increasing by
approximately $20.3 million to approximately $86.1 million from approximately
$65.8 million in the fiscal year ended June 30, 1995. Such revenues increased
$9.1 million to approximately $49.0 million for the six months ended December
31, 1996 from $39.9 million in the comparable prior year period. There can be
no assurance that the Company's recent growth rate can be sustained or that
the Company will be able to manage any future growth successfully. To manage
growth effectively requires that the Company continue to improve its
operational, financial and management information systems, to integrate new
products into its product line, to train, motivate and manage its employees
and to attract and retain senior managers. If the Company's management is
unable to manage any future growth effectively, the Company's business,
results of operations and financial condition could be materially and
adversely affected. See "Dependence on Key Employees," "Management's
Discussion and Analysis of Financial Condition and Results of Operations,"
"Business--Employees" and "Management--Executive Officers and Directors."
 
  The Company's HEP product revenues have declined from approximately $15.4
million in the fiscal year ended June 30, 1992 to approximately $11.0 million
in the fiscal year ended June 30, 1996 and declined from approximately $5.1
million for the six months ended December 31, 1995 to approximately $3.6
million for the six months ended December 31, 1996. These declines were due to
a variety of factors including a decline in United States government funding
for defense and the phase-out of the Company's digitizer products. The Company
expects the decline in HEP revenues to continue. As a consequence, in January
1997 the Company adopted a strategic business plan to reduce costs and improve
asset utilization in its HEP business. Under this plan, the Company is
redirecting its engineering resources within this business unit to focus
principally on the development and sale of signal analysis chip sets and
subsystems for HEP applications as well as new commercial applications. In
connection with the plan, the Company expects to take a series of
reorganization actions resulting in write-downs, principally for inventory and
other asset revaluations, and employee severance. The restructuring plan is
expected to be completed by the end of December 1997 and result in a charge to
fiscal 1997 third quarter results of an estimated $3.9 million ($2.5 million
after taxes). See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
  DEPENDENCE ON KEY EMPLOYEES. The Company's success depends to a significant
degree upon the continuing contributions of its key management, sales,
marketing, research and development and manufacturing personnel, many of whom
would be difficult to replace. The Company does not have long-term employment
contracts with its key personnel, although four of the Company's senior
officers have entered into noncompetition agreements with the Company. The
Company maintains key-man insurance only on the life of Lutz P. Henckels, the
President and Chief Executive Officer, in the amount of $1.5 million. The
Company believes that its future success will depend in large part upon its
ability to continue to attract and retain skilled management, sales,
marketing, research and development and manufacturing personnel. Competition
for such personnel is intense, and there can be no assurance that the Company
will be successful in attracting and retaining such personnel. Failure to
attract and retain key personnel could have a material adverse effect on the
Company's business, results of operations and financial condition. See
"Business--Employees" and "Management--Executive Officers and Directors."
 
  DEPENDENCE ON HIGH-PERFORMANCE DIGITAL OSCILLOSCOPE PRODUCTS . The Company
is primarily engaged in the development, manufacture and sale of high-end
digital oscilloscopes and derives a substantial portion of its revenues from
sales of its principal product families of digital oscilloscopes, the 9300
series and the LC series. Sales of models in the Company's 9300 series and LC
series (including sales of products in the 9400 series, the predecessor to the
9300 series) accounted for 58%, 65% and 79% of the Company's total revenues in
its fiscal years ended June 30, 1994, 1995 and 1996, respectively, and 85% for
the six months ended December 31, 1996. The 9300 series and the LC series are
expected to continue to account for a substantial portion of the Company's
total revenues. A reduction in demand for these products, whether due to the
introduction of competing products or otherwise, would have a material adverse
effect on the Company's business, results of operations and financial
condition. See "Business--Products and Services."
 
 
                                       9
<PAGE>
 
  UNCERTAINTIES REGARDING PATENTS AND PROTECTION OF PROPRIETARY
TECHNOLOGY. The Company currently relies on a combination of patents, trade
secrets, technical expertise and continuing technological research and
development to establish and protect proprietary rights in its products. There
can be no assurance that competitors will not develop similar or functionally
equivalent technology or expertise.
 
  There can be no assurance that third parties will not allege infringement by
the Company of patents and proprietary rights of such parties in the future.
If infringement is alleged, there is no assurance that the necessary licenses
would be available on acceptable terms, if at all, or that the Company would
prevail in any such challenge. In any event, patent and proprietary rights
litigation can be extremely protracted and expensive. See "Technology Dispute
Settlement and License Agreement" and "Business--Intellectual Property
Rights."
 
  LIMITED HISTORY OF PROFITABILITY. The Company reported net income of
approximately $4.3 million, $2.6 million and $200,000 for its fiscal years
ended June 30, 1996, 1995 and 1992, respectively, and $3.7 million for the six
months ended December 31, 1996. The Company reported net losses of
approximately $1.0 million and $150,000 for its fiscal years ended June 30,
1994 and 1993, respectively. There can be no assurance that the growth in
total revenues and the ability to report net income as opposed to a net loss
that the Company has previously experienced can be sustained or that the
Company will be profitable in the future. The Company's multicurrency
revolving credit facility contains a covenant including the requirement that
the Company not incur any net loss during any fiscal year. See "Selected
Consolidated Financial Data" and "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
  REGULATION. As the Company manufactures its products in the United States
and Switzerland and sells its products and purchases parts, components and
sub-assemblies in a number of countries, the Company is subject to legal and
regulatory requirements, particularly the imposition of tariffs and customs
and export controls, in a variety of countries. In addition, the export of
digital oscilloscopes from both the United States and Switzerland is subject
to regulation under the Treaty for Nuclear Non-Proliferation by such
countries.
 
  TECHNOLOGY DISPUTE SETTLEMENT AND LICENSE AGREEMENT. In February 1994, the
Company settled litigation with Tektronix, Inc. ("Tektronix") involving
allegations that the Company's digital oscilloscope products infringed patents
held by Tektronix. As part of the settlement, the Company entered into a
license agreement with respect to such patents. Pursuant to the license
agreement the Company made an initial payment in fiscal 1994 of approximately
$1.5 million. In addition, the Company is required to make future royalty
payments in a minimum aggregate amount of $3.5 million over ten years ending
June 30, 2004 and may be required to make up to an additional $3.5 million in
contingent royalty payments depending on its sales of certain products in
certain territories over the life of the patents. Royalty expense was
approximately $781,000 and $963,000 in fiscal 1995 and 1996, respectively. See
"Business--Intellectual Property Rights." The settlement agreement provides
that Tektronix may terminate the license in the event that the Company
acquires 20% or more of the stock of, or a controlling interest in, any of a
number of specified companies participating in the oscilloscope market or any
of their respective affiliates (each, a "Restricted Company"), or a Restricted
Company acquires 20% or more of the stock of, or a controlling interest in,
the Company or an affiliate of the Company, or any attempt to transfer the
Tektronix license to a Restricted Company is made. This provision of the
settlement could preclude the Company from making an investment in or
acquisition of such companies, and it also could discourage such companies or
another third party from attempting to acquire control of the Company or limit
the price that such a third party might be willing to pay for the Common
Stock. In addition, this provision could limit the price that investors might
be willing to pay in the future for the Common Stock.
 
  EFFECT OF ANTI-TAKEOVER PROVISIONS. Certain provisions of the Company's
Certificate of Incorporation and Amended and Restated By-Laws, as well as the
provisions of the settlement described above under the caption "Technology
Dispute Settlement and License Agreement," could have the effect of making it
more difficult for a third party to acquire, or of discouraging a third party
from attempting to acquire, control of the Company. Such provisions could
limit the price that investors might be willing to pay in the future for the
Common Stock. Certain of these provisions allow the Company to issue preferred
stock with rights senior to those of the Common Stock without any further vote
or action by the stockholders, eliminate the right of
 
                                      10
<PAGE>
 
stockholders to act by written consent and impose various procedural and other
requirements that could make it more difficult for stockholders to effect
certain corporate actions. These provisions could also have the effect of
delaying or preventing a change in control of the Company. The issuance of
preferred stock could decrease the amount of earnings and assets available for
distribution to the holders of Common Stock and could adversely affect the
rights and powers, including voting rights, of the holders of the Common
Stock. In certain circumstances, such issuance could have the effect of
decreasing the market price of the Common Stock. See "Description of Capital
Stock."
 
  VOLATILITY OF STOCK PRICE. Since the completion of the Company's initial
public offering in October 1995, the market price of the Common Stock has
fluctuated significantly. The Company believes that factors such as
announcements of developments related to the Company's business, announcements
of technological innovations or new products or enhancements by the Company or
its competitors, sales by competitors, including sales to the Company's
customers, sales of the Common Stock into the public market, including by
members of management, developments in the Company's relationship with its
customers, partners, distributors and suppliers, shortfalls or changes in
revenue, gross margins, earnings or losses or other financial results from
analysts' expectations, regulatory developments, fluctuations in results of
operations, seasonality and general conditions in the Company's market or the
markets served by the Company's customers or the economy could cause the price
of the Common Stock to fluctuate, perhaps substantially. In addition, in
recent years the stock market in general, and the market for shares of
technology stocks in particular, have experienced extreme price fluctuations,
which have often been unrelated to the operating performance of affected
companies. There can be no assurance that the market price of the Common Stock
will not decline substantially, or otherwise continue to experience
significant fluctuations in the future, including fluctuations that are
unrelated to the Company's operating performance. See "Price Range of Common
Stock."
 
  NO PRESENT INTENTION TO PAY DIVIDENDS. The Company has never declared or
paid cash dividends on its Common Stock and intends to retain all available
funds for use in the operation and expansion of its business. The Company
therefore does not anticipate that any cash dividends will be declared or paid
in the foreseeable future. See "Dividend Policy."

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 658,838 shares of
Common Stock offered by the Company hereby, at an assumed public offering
price of $33.25 per share (the last reported sales price of the Common Stock
on the Nasdaq National Market on February 19, 1997), and after deducting
underwriting discounts and commissions and estimated offering expenses, are
estimated to be $19,706,514 ($29,132,889 if the Underwriters' over-allotment
option to purchase up to 300,000 shares is exercised in full). The Company
will not receive any proceeds from the sale of Common Stock by the Selling
Stockholders. See "Principal and Selling Stockholders."
 
  The Company anticipates using a portion of the net proceeds of the Offering
(i) to repay borrowings under its multicurrency revolving credit facility to
be used to repurchase an estimated 350,000 shares of Common Stock held by the
ESOT, a greater than 5% stockholder of the Company, at a price per share equal
to the initial offering price of the shares of Common Stock offered to the
public in the Offering, see "Principal and Selling Stockholders--Repurchase by
the Company of Shares from the ESOT," and (ii) to repay the then remaining
outstanding advances under its multicurrency revolving credit facility ($7.0
million as of December 31, 1996, bearing interest at an interest rate of 8.25%
as of such date). Amounts repaid under the multicurrency revolving credit
facility may be reborrowed subject to the terms and conditions thereof. Any
remaining net proceeds will be used for general corporate purposes and may be
used to fund development or acquisitions of complementary businesses, products
or technologies, although there are no existing commitments with respect to
any such transactions. Pending such uses, the Company intends to invest the
remaining net proceeds in United States government securities or other short-
term, investment-grade, interest-bearing securities. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

                                DIVIDEND POLICY
 
  The Company has never declared or paid cash dividends on its Common Stock
and intends to retain all available funds for use in the operation and
expansion of its business. The Company therefore does not anticipate that any
cash dividends will be declared or paid in the foreseeable future. Any
determination to declare or pay cash dividends in the future will be at the
discretion of the Company's Board of Directors and will depend on, among other
things, the Company's financial condition and results of operations, the terms
of any outstanding shares of preferred stock, requirements of applicable law
and other considerations deemed relevant by the Company's Board of Directors.
See "Description of Capital Stock."
 
                                CAPITALIZATION
 
  The following table sets forth the capitalization of the Company as of
December 31, 1996 on an actual basis and as adjusted to give effect to (i) the
sale of 658,838 shares of Common Stock offered by the Company hereby at an
assumed offering price of $33.25 per share (the last reported sales price of
the Common Stock on the Nasdaq National Market on February 19, 1997), after
deducting underwriting discounts and commissions and estimated offering
expenses payable by the Company and the application of the estimated net
proceeds therefrom, (ii) the repurchase by the Company of an estimated 350,000
shares of Common Stock from the ESOT at a price per share equal to the initial
offering price of the shares of Common Stock offered to the public in the
Offering and (iii) the issuance of 583,011 shares of Common Stock upon the
assumed conversion of 673,913 stock warrants held by the Selling Stockholders
with an exercise price of $4.485 per share at an assumed offering price of
$33.25 per share. See "Use of Proceeds" and "Principal and Selling
Stockholders." This table should be read in conjunction with the Consolidated
Financial Statements and Notes appearing elsewhere in this Prospectus.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  Since the Company's founding in 1964, the Company has been designing,
manufacturing and selling high performance signal analyzers to scientists
engaged in HEP research. Since calendar year 1983, the Company has applied its
HEP technology to the design and development of digital oscilloscopes, its
principal product. Digital oscilloscopes are signal analyzers that capture
electronic signals, convert them to digital form and perform sophisticated
measurements and analyses. The Company's digital oscilloscope products are
used by design engineers and researchers in a broad range of industries,
including electronics, computers and communications.
 
  In 1985, the Company introduced its first digital oscilloscope product.
Commencing in fiscal 1994, the Company began to focus its digital oscilloscope
product offerings on the high end market, which has resulted in a significant
increase in revenues. The Company's total revenues were $63.8 million, $82.3
million and $101.5 million for the fiscal years ended June 30, 1994, 1995 and
1996, respectively, and $55.2 million for the six months ended December 31,
1996. Sales of digital oscilloscopes and related products grew from
approximately 75% of the Company's total revenues for fiscal year 1994 to
approximately 89% of the Company's total revenues for the six months ended
December 31, 1996.
 
  In 1993, the Company adopted a performance improvement strategy pursuant to
which the Company hired new managers, including a new Chief Executive Officer,
to supplement the existing management team. As part of the performance
improvement strategy, the Company's worldwide sales organization was
restructured, the Company's United Kingdom research and development facility
was closed and the Company's product offerings were streamlined to focus
primarily on a single family of high-performance digital oscilloscopes, the
9300 series. In fiscal 1997, the Company expanded its high-end market product
offerings with a second family of products, the LC series of digital
oscilloscopes. The primary focus on high-performance products, together with
management's continued emphasis on operational improvements, have resulted in
efficiency gains in product development, manufacturing, marketing, sales and
service. These factors, together with an increase in revenues, have
contributed to an increase in operating margin from 4.8% for fiscal year 1994
to 8.5% for fiscal year 1996 and 9.8% for the six months ended December 31,
1996. The Company believes that certain models of its 9300 series and LC
series offer the highest sampling rate, and others the longest record length,
available to date in the digital oscilloscope market.
 
  The Company's original digital oscilloscope technology was derived from its
historical efforts in developing products for high energy physics ("HEP")
research. Since its founding in 1964, the Company has designed and
manufactured signal analyzers for a number of leading HEP research
laboratories. The Company's signal analyzers were used in Nobel Prize winning
experiments at CERN (Centre Europeen pour la Recherche Nucleaire) near Geneva,
Switzerland and the Brookhaven National Laboratory in Upton, New York. Sales
of HEP products have been declining and accounted for approximately 21%, 15%
and 11% of the Company's total revenues for the fiscal years ended June 30,
1994, 1995 and 1996, respectively, and 7% of the Company's total revenues for
the six months ended December 31, 1996. The Company expects the decline in HEP
revenues to continue. As a consequence, in January 1997 the Company adopted a
strategic business plan to reduce costs and improve asset utilization in its
HEP business. Under this plan, the Company is redirecting its engineering
resources within this business unit to focus principally on the development
and sale of signal analysis chip sets and subsystems for HEP applications as
well as new commercial applications. In connection with the plan, the Company
expects to take a series of reorganization actions resulting in write-downs,
principally for inventory and other asset revaluations, and employee
severance. The restructuring plan is expected to be completed by the end of
December 1997 and to result in a charge to fiscal 1997 third quarter results
of an estimated $3.9 million ($2.5 million after taxes).
 
  The Company has manufacturing facilities in both the United States and
Switzerland and purchases parts, components and sub-assemblies from a variety
of vendors around the world in a variety of currencies and sells its products
around the world in a variety of currencies. This subjects the Company to
certain risks including
 
                                      16
<PAGE>
 
fluctuations in foreign currency exchange rates, changes in government
policies and legal and regulatory requirements, political instability,
transportation delays and the imposition of tariffs and export controls. For
information with respect to the risks arising from fluctuations in foreign
currency exchange rates and certain measures adopted by the Company in an
effort to mitigate to a degree such risks, see "Risk Factors--International
Operations and Foreign Currency Exchange Risks" and "Business--Foreign
Currency Exchange."
 
  In response to the continuing decline in HEP manufacturing and revenues and
in an effort to increase absorption of the fixed costs of its Chestnut Ridge
facility, in June 1995, the Company commenced manufacturing at such facility
its Model 935X digital oscilloscope to supplement its manufacturing operations
in Geneva. In fiscal 1996 and 1997, the Company has increased oscilloscope
production at Chestnut Ridge to include its Model 938X and its newest digital
model oscilloscope, the Model LC574. This higher production volume has
increased operating efficiencies at Chestnut Ridge and has generated operating
income for the six months ended December 31, 1996, as opposed to an
approximately break-even level of area operating income (loss) for fiscal 1996
in such geographic area. See Note 8 of Notes to Consolidated Financial
Statements. However, the reorganization actions anticipated in the third
quarter of fiscal 1997 related to the HEP business, together with costs
associated with continued investment in research and development for the LAN
monitor product, are expected to result in an operating loss for the Company's
U.S. operations for the full fiscal year ended June 30, 1997.
 
  The Company anticipates using a portion of the net proceeds of the Offering
to repay borrowings under its multicurrency revolving credit facility to be
used to repurchase an estimated 350,000 shares of Common Stock held by the
ESOT, see "Principal and Selling Stockholders--Repurchase by the Company of
Shares from the ESOT," and to pay down the then remaining outstanding advances
under its floating-rate multicurrency revolving credit facility ($7.0 million
as of December 31, 1996, bearing interest at an interest rate of approximately
8.25% as of such date). Amounts repaid under the multicurrency revolving
credit facility may be reborrowed subject to the terms and conditions thereof.
Any remaining net proceeds from the Offering will be used for general
corporate purposes and may be used to fund development or acquisitions of
complementary businesses, products or technologies, although there are no
commitments or understandings with respect to any such transactions. Pending
such uses, the Company intends to invest the net proceeds in United States
government securities or other short-term, investment-grade, interest-bearing
securities.

 Comparison of Six Months Ended December 31, 1996 and 1995
 
  Total revenues increased to $55.2 million in the six months ended December
31, 1996 from $47.2 million for the six months ended December 31, 1995, or
17%, and represented record mid-year revenues for the Company. Revenues
increased primarily as a result of an increase in unit sales of digital
oscilloscopes and related products. For the six months ended December 31,
1996, an increase in revenues in the United States and the rest of the world
other than Europe (principally Japan and the rest of Asia) was partially
offset by a decrease in revenues in Europe, as compared to the six months
ended December 31, 1995. The trends with respect to geographic area revenues
have continued to date in the Company's third fiscal quarter.
 
  The increase in revenues was also offset in part by approximately $2.3
million for the six months ended December 31, 1996 attributable to the net
impact of the strengthening of the United States dollar versus the Japanese
yen, Swiss franc, French franc and German deutschemark, as compared to the
exchange rates prevailing in the same period of the prior fiscal year. Based
on exchange rates as of the date of this Prospectus, the Company expects that
revenues will continue to be adversely impacted by the strengthening of the
U.S. dollar.
 
  Revenues from sales of digital oscilloscopes and related products increased
to $49.0 million for the six months ended December 31, 1996 from $39.9 million
for the six months ended December 31, 1995, an increase of 23%. This increase
in revenues was primarily attributable to a 25% increase in unit sales of the
higher-end products in the Company's 9300 series of digital oscilloscopes,
including the Model 938X introduced in June 1996, together with sales of the
LC334/534 series of color digital oscilloscopes first introduced in the second
quarter of fiscal 1997. In addition, there was a marginal increase in average
selling prices for the Company's digital oscilloscopes and related products.

  Revenues from sales of HEP products declined 29% to $3.6 million in the six
months ended December 31, 1996 from $5.1 million in the comparable prior year
period. The Company in recent years has experienced a continuing decrease in
HEP revenues due to a variety of factors, including a decline in United States
government funding for defense and the phase-out of the Company's digitizer
products. The Company believes that revenues from sales of HEP products, which
represented approximately 7% of total revenues for the six months ended
December 31, 1996 as compared to approximately 11% of total revenues in the
same period of fiscal 1996, are expected to continue to represent a declining
portion of its total revenues in the future, attributable in part to lower
anticipated order volumes. As a consequence, in January 1997 the Company
adopted a strategic business plan to reduce costs and improve asset
utilization in its HEP business. Under this plan, the Company is redirecting
its engineering resources within this business unit to focus principally on
the development and sale of signal analysis chip sets and subsystems for HEP
applications as well as new commercial applications. In connection with the
plan, the Company expects to take a series of reorganization actions resulting
in write-downs, principally for inventory and other asset revaluations, and
employee severance. The restructuring plan is expected to be completed by the
end of December 1997 and result in a charge to fiscal 1997 third quarter
results of an estimated $3.9 million ($2.5 million after taxes).
 
  Service and other revenues increased to $2.5 million for the six months
ended December 31, 1996 from $2.2 million in the comparable prior year period,
or 15%, due primarily to the increase in sales of digital oscilloscopes and
related products.
 
  Gross profit for the six months ended December 31, 1996 was 56.6% of
revenues, compared to 54.6% for the comparable prior year period. This growth
was due primarily to increased revenues from higher sales volume of certain
higher margin 9300 series and LC series digital oscilloscopes and reduced HEP
sales, which carry a lower margin, coupled with reduced material costs and
increased operating efficiencies at the Company's manufacturing facility in
Chestnut Ridge, New York.
 
  As a percentage of total revenues, selling, general and administrative
expenses declined to 33.6% for the six months ended December 31, 1996 compared
to 33.9% for the six months ended December 31, 1995. Selling, general and
administrative expenses increased in absolute dollar terms as the Company
expanded sales management and staff at each of its regional sales headquarters
and incurred additional sales commissions due to higher sales volume and the
expansion of administrative management and support staff.
 
  Research and development expenses increased to $7.3 million in the six
months ended December 31, 1996 from $6.3 million for the six months ended
December 31, 1995, or 15%. This higher level of research and development
expenses reflected an increase in connection with introductions of new digital
oscilloscopes and related products and continued development of a LAN monitor.
See "Business--Research and Development." As a percentage of total revenues,
research and development expenses were 13.2% in the six months ended December
31, 1996 compared to 13.4% for the six months ended December 31, 1995.
 
  Operating income increased 57% to $5.4 million for the six months ended
December 31, 1996 from $3.5 million for the six months ended December 31,
1995. As a percentage of total revenues, operating income was 9.8% for the six
months ended December 31, 1996 as compared to 7.3% for the six months ended
December 31, 1995. The increase in operating income was due primarily to
increased revenues in the current year coupled with improved operating
efficiencies and other factors listed above.
 
  Net interest and financing charges, included in other (income) expenses,
net, decreased to $306,000 for the six months ended December 31, 1996 compared
to $576,000 for the six months ended December 31, 1995. The decrease was due
primarily to reduced levels of outstanding debt, paid with funds received in
the second quarter of fiscal 1996 from the Company's initial public offering.
Other (income) expenses, net, in the six month periods ended December 31, 1996
and 1995 included currency exchange gains of approximately $609,000 and
$137,000, respectively.
 
                                      19
<PAGE>
 
  The Company's effective income tax rate for the six months ended December
31, 1996 was 35%. Currently, the Company's Swiss subsidiary operates under a
tax agreement with the Canton of Geneva pursuant to which the effective tax
rate on income with respect to such subsidiary is approximately 15%. This
agreement is in effect through the fiscal year ended June 30, 2000.
 
  Income before extraordinary charge increased 90% to $3.7 million for the
first half of fiscal 1997 compared to $2.0 million in the comparable prior
year period. Income before extraordinary charge for the first half of fiscal
1997 as a percentage of total revenues was 6.7% compared to 4.2% for the
comparable prior year period. The improvement in fiscal 1997 was due primarily
to increased revenues, improved gross margins, lower interest costs and
favorable exchange gains.
 
 Comparison of Fiscal Years 1996 and 1995
 
  Total revenues increased to $101.5 million in 1996 from $82.3 million in
1995, or 23%, and represented record full-year revenues for the Company.
Revenues increased primarily as a result of an increase in sales of higher
margin digital oscilloscopes and related products. On a geographic basis,
total revenues increased to $42.2 million in 1996 from $35.8 million in 1995,
or 18%, in the United States, to $42.3 million in 1996 from $33.3 million in
1995, or 27%, in Europe and to $17.0 million in 1996 from $13.2 million in
1995, or 29%, in the rest of the world, principally Japan and the rest of
Asia.
 
  Revenues from sales of digital oscilloscopes and related products increased
to $86.1 million in 1996 from $65.8 million in 1995, or 31%. Sales of digital
oscilloscopes and related products, in terms of units, increased to
approximately 6,000 in 1996 from approximately 5,100 in 1995, or 18%. This
increase in revenues and units was primarily attributable to an increase in
sales of the higher-end products in the Company's 9300 series of digital
oscilloscopes which, in terms of units, increased to approximately 5,300 in
1996 from approximately 4,000 in 1995, or 33%. Average selling prices of
digital oscilloscopes and related products increased by 11% as compared to
1995 principally as a result of a continuing change in the Company's product
mix towards higher-end products.
 
  Revenues from sales of HEP products decreased to $11.0 million in 1996 from
$12.3 million in 1995, or 11%. The Company in recent years has experienced a
continuing decrease in HEP revenues due to a variety of factors, including a
decline in United States government funding for defense and the phase-out of
the Company's digitizer products. The Company believes that revenues from
sales of HEP products, which represented approximately 11% of total revenues
in 1996 as compared to approximately 15% of total revenues in 1995, are likely
to continue to represent a declining portion of its total revenues in the
future, attributable in part to lower anticipated order volumes.
 
  Service and other revenues increased to $4.5 million in 1996 from $4.2
million in 1995, or 6%, due primarily to the continued increase in marketing
of service and support programs for digital oscilloscopes and related products
and increased sales of upgrades for such products.
 
  Gross profit for fiscal 1996 was 55.1% of revenues compared to 54.1% for the
prior year. This growth was due primarily to increased revenues from higher
sales volume of certain higher margin 9300 series digital oscilloscopes,
coupled with increased operating efficiencies at the Company's manufacturing
facility in Chestnut Ridge, New York. Approximately $933,000 of the increase
in cost of sales for 1996 was attributable to the weakening United States
dollar versus the Swiss franc as compared to the exchange rates prevailing in
1995.
 
  Selling, general and administrative expenses increased to $34.6 million in
1996 from $28.0 million in 1995, or 24%. As a percentage of total revenues,
selling, general and administrative expenses was 34.1% in 1996 compared to
34.0% in 1995. These expenses increased as the Company expanded sales
management and support staff at its European, Asian and United States regional
sales headquarters and incurred additional sales commissions due to higher
sales volume and the hiring of additional administrative support staff.
Approximately $781,000 of the increase in selling, general and administrative
expense in 1996 was attributable to the weakening of the U.S. dollar versus
the Swiss franc as compared to the exchange rates prevailing in 1995.
 
                                      20
<PAGE>
 
  Research and development expenses increased to $12.6 million in 1996 from
$10.3 million in 1995, or 22%. This higher level of research and development
expenses reflects an increase in expenditures for prototype and development
costs of custom integrated circuits for use in digital oscilloscopes and
related products and initial development of a LAN monitor. As a percentage of
total revenues, research and development expenses were 12.5% in both 1996 and
1995. The Company's objective is to maintain annual research and development
expenses at approximately 12% to 13% of total revenues.
 
  Operating income increased to $8.7 million in 1996 from $6.2 million in
1995, or 39%. As a percentage of total revenues, operating income was 8.5% in
1996 as compared to 7.6% in 1995. The increase in operating income was due
primarily to increased revenues in 1996 as compared to 1995 coupled with
improved operating efficiencies and other factors listed above.
 
  Net interest and financing charges, included in other (income) expenses,
net, decreased to $672,000 in 1996 from $1.5 million in 1995, or 56%. The
decrease in fiscal 1996 was due primarily to reduced levels of debt, paid down
from funds received in the second quarter of fiscal 1996 from the Company's
initial public offering. Average borrowing levels were $7.6 million in 1996 as
compared to $16.6 million in 1995. Operating results in fiscal 1996 and 1995
included currency exchange gains (losses) of approximately $539,000 and
($684,000), respectively.
 
  The Company's effective income tax rate for 1996 was 35%. Currently, the
Company's Swiss subsidiary operates under a tax agreement with the Canton of
Geneva pursuant to which the effective tax rate on income with respect to such
subsidiary was approximately 15% in 1996. This agreement is in effect through
the fiscal year ended June 30, 2000.
 
  During fiscal 1996, an extraordinary charge of $1.3 million was incurred
relating to the write-off of deferred financing costs associated with the
early retirement of debt paid from the proceeds received from the Company's
initial public offering.
 
  Income before extraordinary charge increased 113% to $5.6 million in 1996,
representing record full-year earnings for the Company, compared to net income
of $2.6 million for 1995. Income before extraordinary charge in 1996, as a
percentage of total revenues, was 5.5% compared to 3.2% in 1995. The
improvement in 1996 was due primarily to increased revenues, improved
operating efficiencies and operating margins and the gain on currency
exchange.
 
 Comparison of Fiscal Years 1995 and 1994
 
  Total revenues increased to $82.3 million in 1995 from $63.8 million in
1994, or 29%, primarily as a result of an increase in sales of digital
oscilloscopes and related products. On a geographic basis, total revenues
increased to $35.8 million in 1995 from $29.4 million in 1994, or 22%, in the
United States, to $33.3 million in 1995 from $26.1 million in 1994, or 28%, in
Europe and to $13.2 million in 1995 from $8.4 million in 1994, or 58%, in the
rest of the world, principally Japan and the rest of Asia.
 
  Revenues from sales of digital oscilloscopes and related products increased
to $65.8 million in 1995 from $47.6 million in 1994, or 38%. Sales of digital
oscilloscopes and related products, in terms of units, increased to
approximately 5,100 in 1995 from approximately 3,900 in 1994, or 30%. This
increase in revenues and units was primarily attributable to an increase in
sales of the Company's 9300 series of digital oscilloscopes which, in terms of
units, increased to approximately 4,000 in 1995 from approximately 2,900 in
1994, or 37%. Average selling prices of digital oscilloscopes and related
products increased by 7% as compared to 1994 principally as a result of a
change in the Company's product mix towards higher-end products.
 
  Revenues from sales of HEP products decreased to $12.3 million in 1995 from
$13.5 million in 1994, or 9%. The Company in recent years has experienced a
continuing decrease in HEP revenues due to a variety of factors, including a
decline in United States government funding for defense and the phase-out of
the Company's
 
                                      21
<PAGE>
 
digitizer products. Revenues from sales of HEP products represented
approximately 15% of total revenues in 1995 as compared to approximately 21%
of total revenues in 1994.
 
  Service and other revenues increased to $4.2 million in 1995 from $2.7
million in 1994, or 56%, due primarily to increased marketing of service and
support programs for digital oscilloscopes and related products and increased
sales of upgrades for such products.
 
  Approximately $3.3 million of the increase in total revenues for 1995 was
attributable to the net impact of the weakening of the United States dollar
versus the Japanese yen, Swiss franc and German deutschemark, offset in part
by the strengthening of the United States dollar versus the Italian lira, in
each case as compared to the exchange rates prevailing in 1994.
 
  Gross profit increased to $44.5 million in 1995 from $35.6 million in 1994,
or 25%. This growth was due primarily to increased revenues from sales of the
Company's 9300 series of digital oscilloscopes, manufactured at the Company's
facility in Geneva, Switzerland. The gross profit margin decreased to 54.1% in
1995 from 55.7% in 1994 due principally to the inclusion in 1995 of technology
license royalties of approximately $700,000, or 1% of total revenue, the
under-utilization of the Company's Chestnut Ridge, New York manufacturing
facility resulting from the phase-out of older generation oscilloscopes, the
reduction in sales of digitizer products produced in Chestnut Ridge and a
change in product mix (including service revenues). In an effort to increase
absorption of the fixed costs of the Chestnut Ridge facility, in June 1995 the
Company commenced manufacturing at such facility of its Model 935x digital
oscilloscope to supplement its manufacturing operations in Geneva.
Approximately $1.6 million of the increase in cost of sales for 1995 was
attributable to the weakening of the United States dollar versus the Swiss
franc and the Japanese yen as compared to the exchange rates prevailing in
1994.
 
  Selling, general and administrative expenses increased to $28.0 million in
1995 from $22.8 million in 1994, or 22%. However, as a percentage of total
revenues, selling, general and administrative expenses decreased to 34.0% in
1995 from 35.8% in 1994. Selling expenses increased approximately $2.4 million
as the Company expanded management and support staff at its European, Asian
and United States regional sales headquarters and hired additional sales
engineers in Japan. General and administrative expenses also increased by
approximately $800,000 due principally to the hiring of additional
administrative support staff and improvements made to the Company's
information systems. In addition, selling, general and administrative expenses
increased by approximately $700,000 principally due to higher advertising and
promotional expenses related to the 9300 series of digital oscilloscopes.
Approximately $1.3 million of the increase in selling, general and
administrative expenses in 1995 was attributable principally to the weakening
of the United States dollar versus the Swiss franc and Japanese yen as
compared to the exchange rates prevailing in 1994.
 
  Research and development expenses increased to $10.3 million in 1995 from
$8.8 million in 1994, or 17%. This higher level of research and development
expenses reflects an increase in expenditures for the development of custom
integrated circuits for use in digital oscilloscopes and related products to
$1.5 million in 1995 from $700,000 in 1994. As a percentage of total revenues,
research and development expenses decreased to 12.5% in 1995 from 13.7% in
1994. This percentage decrease was due primarily to a significant growth in
revenues and slower growth in overall research and development expenses.
 
  Operating income increased to $6.2 million in 1995 from $3.1 million in
1994, or 104%. As a percentage of total revenues, operating income was 7.6% in
1995 as compared to 4.8% in 1994. The increase in operating income was due
primarily to the factors noted above as well as the absence in 1995 of the
restructuring costs incurred in 1994.
 
  Net interest and financing charges, included in other (income) expenses,
net, increased to $1.5 million in 1995 from $1.2 million in 1994, or 29%, due
primarily to higher average levels of debt outstanding. Average borrowing
levels were $16.6 million in 1995 as compared to $13.8 million in 1994.
Operating results in fiscal 1995 and 1994 included currency losses of
approximately $684,000 and $512,000, respectively.
 
                                      22
<PAGE>
 
  The Company's effective income tax rate for 1995 was 35%. The Company's
Swiss subsidiary operates under a tax agreement with the Canton of Geneva
pursuant to which the effective tax rate on income with respect to such
subsidiary was approximately 12% in 1995. This agreement is in effect through
the fiscal year ended June 30, 2000.
 
  Net income increased to $2.6 million in 1995 from a net loss of $1.0 million
for 1994. Net income in 1995 as a percentage of total revenues was 3.2%; in
1994, the net loss represented (1.6)% of total revenues. The improvement in
1995 was due primarily to the factors noted above as well as the incurrence in
1994 of the $1.5 million initial settlement payment included under technology
dispute settlement costs.

  The Company historically has experienced somewhat lower activity during its
first fiscal quarter than in other fiscal quarters due, it believes,
principally to the lower level of orders and market activity during the summer
months, particularly in Europe. The Company believes this seasonable aspect of
its business is likely to continue in the future.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  In October 1995, the Company completed an initial public offering of
1,500,000 shares of Common Stock at $12.00 per share, generating net proceeds
to the Company of approximately $15.3 million. These net proceeds, combined
with net cash generated from operating activities of $8.3 million in fiscal
1996 allowed the Company to reduce funded debt (current debt, long-term debt
and capitalized leases) to 13% of total capital at June 30, 1996. This
compares to a level of funded debt to total capital ranging from 48% to 54% at
the end of fiscal years 1992 through 1995. Funded debt was 16% of total
capital at December 31, 1996. The Company had working capital of $21.8
million, $32.0 million and $37.1 million at the end of fiscal 1995 and fiscal
1996 and at December 31, 1996, respectively. Cash and cash equivalent balances
of $9.4 million at December 31, 1996 primarily reflected short-term deposits
in Europe.
 
  Cash generated from operating activities was $1.0 million and $8.3 million
in fiscal 1995 and fiscal 1996, respectively. Improved operating earnings
coupled with significant asset management improvement accounted for the
favorable cash flow in fiscal 1996. Cash used in operating activities for the
first half of fiscal 1997 amounted to $1.8 million. The use of cash reflected
the fact that the increase in earnings was more than offset by increases in
accounts receivable, inventory and current assets needed to support revenue
growth. Combined accounts receivable and inventories at year-end were 49% of
fiscal 1994 revenues compared to 45% of fiscal 1995 revenues and 40% of fiscal
1996 revenues. Combined accounts receivable and inventories as of December 31,
1996 represented 43% of the first half of fiscal 1997 revenues annualized.
 
                                      24

  Capital expenditures were $1.5 million, $2.9 million and $3.7 million in
fiscal 1994, 1995 and 1996, respectively, and $2.1 million for the first half
of fiscal 1997 compared to $1.6 million in the comparable fiscal 1996 period.
These capital expenditures were primarily for assembly, research, design and
test equipment, facilities improvements and information systems. The Company
anticipates that its capital expenditures for all of fiscal 1997 will
approximate $7.0 million, primarily for facilities improvement, design and
test equipment and information systems, which expenditures are expected to be
funded from internally generated cash flow.
 
  In December 1995, the Company finalized a $15 million unsecured
multicurrency credit agreement with several commercial banks, which matures in
January 1999. At December 31, 1996, $7.0 million was borrowed under this
facility. The Company has met its financial covenants that include maintaining
specified financial ratios and positive levels of net income and limitations
on capital expenditures and lease obligations. See Note 5 of Notes to
Consolidated Financial Statements.
 
  In addition, the Company maintains certain foreign borrowing and overdraft
facilities, principally a three million Swiss franc ($2.4 million using the
U.S. dollar/Swiss franc exchange rate as of December 31, 1996) multicurrency
revolving credit agreement cancelable upon notice by the bank or the Company.
At December 31, 1996, there were no outstanding borrowings under this
facility.
 
  The Company anticipates using a portion of the net proceeds of the Offering
to repay borrowings under its multicurrency revolving credit facility to be
used to repurchase an estimated 350,000 shares of Common Stock held by the
ESOT, a greater-than-5% stockholder of the Company, at a price per share equal
to the initial offering price of the shares of Common Stock offered to the
public in the Offering, see "Principal and Selling Stockholders--Repurchase by
the Company of Shares from the ESOT," and to repay the then remaining
outstanding advances under its multicurrency revolving credit facility ($7.0
million as of December 31, 1996, bearing interest at an interest rate of 8.25%
as of such date). See "Use of Proceeds."
 
  The Company anticipates that the net proceeds of this Offering, amounts
available under its multicurrency revolving credit facility, cash on hand and
internally generated cash flow will be sufficient to fund working capital and
capital expenditure requirements for at least the next twelve months.

                                   BUSINESS
 
  LeCroy Corporation develops, manufactures and sells signal analyzers,
principally high-performance digital oscilloscopes, and related products.
Digital oscilloscopes capture electronic signals, convert them to digital form
and perform sophisticated measurements and analyses. The Company's digital
oscilloscope products are used by design engineers and researchers in a broad
range of industries, including electronics, computers and communications.
 
  The Company's original digital oscilloscope technology was derived from its
historical efforts in developing products for scientists engaged in HEP
research. Since its founding in 1964, the Company has designed and
manufactured signal analyzers for a number of leading HEP research
laboratories. The Company's signal analyzers were used in Nobel Prize-winning
experiments at CERN (Centre Europeen pour la Recherche Nucleaire) near Geneva,
Switzerland and the Brookhaven National Laboratory in Upton, New York.
 
  In 1985, the Company introduced its first digital oscilloscope product.
Subsequently, the Company expanded its digital oscilloscope product offerings
to include a variety of models with a broad range of capabilities to address
most segments of the digital oscilloscope market. Commencing in fiscal 1994,
the Company began to concentrate its digital oscilloscope product offerings in
the high-end market by offering a single high-performance product family, its
9300 series. In fiscal 1997, the Company expanded its high-end market product
offering with a second family of products, the LC series of digital
oscilloscopes. The Company believes that certain models of its 9300 series and
LC series offer the highest sampling rate, and others the longest record
length, available to date in the digital oscilloscope market. The Company's
shift towards the high end digital oscilloscope market has resulted in a
significant increase in revenues. The Company's total revenues were $63.8
million, $82.3 million and $101.5 million for the fiscal years ended June 30,
1994, 1995 and 1996, respectively, and $55.2 million for the six months ended
December 31, 1996. Sales of digital oscilloscopes and related products grew
from approximately 75% to approximately 89% of the Company's total revenues
from fiscal 1994 to the six months ended December 31, 1996.
 
INDUSTRY BACKGROUND
 
  Overview. Researchers, engineers and field technicians rely on test and
measurement instrumentation such as signal analyzers in designing, developing
and servicing electronic equipment. When designing and developing electronic
circuits, researchers and engineers use signal analyzers to ensure that the
circuits are performing as designed. Field technicians use such instruments to
diagnose electronic equipment to determine whether it is performing as
intended.
 
  The most general-purpose test and measurement instrument used for signal
analysis is the digital oscilloscope. Digital oscilloscopes are signal
analyzers that, like their earlier analog counterparts, can display a
representation of an electronic signal's "shape," which is essentially a
measure of a signal's voltage as a function of time. Digital oscilloscopes,
however, go beyond the capabilities of analog oscilloscopes in that they
capture a signal in digital form by sampling it over time and storing the data
or measurements in memory. The stored signal can then be viewed later and,
more importantly, the instrument can perform various analyses on the stored
data.
 
  During the past few decades, there has been an increasing proliferation of
electronics in general and digital electronics in particular. The growth in
digital electronics has been driven primarily by the growth in stand-alone
computers and related systems, the increase in embedded digital controls
within other electronic and electrical devices and the rapid increase in
digital communications. Combined with the general growth in the quantity of
digital electronics, there has been a substantial increase in processing
speed. For example, processing speeds of personal computers have increased
dramatically in recent years from about 33 MHz to more than 200 MHz and
sophisticated communications equipment transmits data at rates that exceed 1
gigabit per second.
 
                                      26

  Signal shape analysis is becoming increasingly important as data rates in
applications such as computers, local area networks (LANs) and
telecommunications systems increase. Within a given digital circuit, it takes
a finite amount of time for a digital signal to change from a "zero" or "off"
state to a "one" or "on" state. As digital data rates increase, signals within
a circuit may not have sufficient time to cleanly change from a "zero" to a
"one" or vice-versa. This distorts, or changes the shape of the digital
signal, which can lead to computation or information errors. To identify such
problems, engineers use digital oscilloscopes to analyze the signal's shape,
which is not generally possible using other measurement and analysis
instruments (such as protocol analyzers or logic analyzers).
 
  Technology. The basic elements of a digital oscilloscope are shown below.
They are: (i) an amplifier, which amplifies the input signal so that it can be
measured by the oscilloscope; (ii) an analog-to-digital converter ("ADC"),
which converts the analog input signal into digital form by translating it
into a series of sample points that are then measured and transformed into
digital codes representing the signal samples; (iii) an acquisition memory
system ("memory"), which stores the resulting digital data; (iv) a processor,
which controls the entire system and performs special monitoring and
measurement functions; and (v) a display system, which translates the stored
data into a graphic display of the original signal shape.
 
 
                                    (CHART)
 
 
  The following performance measures characterize a digital oscilloscope:
 
  .  BANDWIDTH refers to the highest frequency signal that a digital
     oscilloscope can capture accurately. Generally expressed in megahertz
     ("MHz") or gigahertz ("GHz"), bandwidth is a measure of the
     oscilloscope's ability to respond quickly to changes in the input signal
     and produce an accurate representation of the signal.
 
  .  SAMPLE RATE refers to the rate at which a digital oscilloscope measures
     input signals. Generally expressed in megasamples per second ("MS/s") or
     gigasamples per second ("GS/s"), the higher the sample rate the greater
     the accuracy of the representation of that signal produced by the
     digital oscilloscope.
 
  .  RECORD LENGTH refers to the maximum number of samples that a digital
     oscilloscope can store in memory. Generally expressed as a number of
     sample points or bytes, record length is a measure of the maximum signal
     duration that the digital oscilloscope can store in memory at a given
     sample rate. A digital oscilloscope must have a long enough record
     length to accommodate the longest-duration input signals the user needs
     to analyze, at a sample rate high enough to produce accurate
     representations of those signals.

  .  PROCESSING POWER of a digital oscilloscope refers to the instrument's
     capability to rapidly display the shape of an input signal and analyze
     its characteristics. The higher the processing power, the more
     sophisticated the analysis that can be performed by the digital
     oscilloscope.
 
  Users require digital oscilloscopes with a certain combination of these
attributes best suited to their specific applications. For example,
sophisticated telecommunications systems operate at data transmission rates of
hundreds of millions of bits per second. To measure and analyze these signals,
a digital oscilloscope must have a bandwidth of 1 GHz or greater, a sample
rate of several billions of samples per second, long record length and
powerful processing capabilities.
 
  Market. The Company believes that the digital oscilloscope market is
generally segmented according to bandwidth, and that with advances in
technology, the bandwidth requirements of each market segment will increase.
Products in the low-end or commodity segment of the market (less than 200
MHz), cannot capture fast, long, complex signals. Such products typically do
not have the appropriate combination of bandwidth, sample rate and memory that
is needed for analysis of long complex signals. These instruments typically
sell for under $5,000. The high-performance market segment (bandwidth of
greater than 200 MHz) is characterized by instruments with high sample rates
(from 100 MS/s to 4 GS/s) and long record lengths (from 10,000 to 8 million
sample points) and greater processing power to perform more sophisticated
analyses. These high-performance digital oscilloscopes typically range in
price from $5,000 to $37,500, although certain very high bandwidth
oscilloscopes for specialized applications are priced above $37,500.
 
  According to Prime Data, Inc. ("Prime Data"), an independent industry survey
organization, digital oscilloscope sales, excluding handhelds, grew from
$586.5 million in 1992 to $755.0 million in 1996. Prime Data estimates that
the four largest suppliers of digital oscilloscopes, exclusive of handheld
models, and their approximate respective market shares for calendar 1996 were
Tektronix with 42.5%, Hewlett-Packard Company with 18.1%, LeCroy with 12.4%
and Fluke Corporation with 4.9%.
 
  The Company's 9300 and LC digital oscilloscope product families are targeted
at customers in the high-performance market segment. See "Products and
Services."
 
LECROY PRODUCT ADVANTAGES
 
  The Company believes that its expertise in signal shape analysis has enabled
it to develop digital oscilloscopes that provide key advantages over
competitive offerings:
 
  .  HIGH SAMPLE RATES. The Company's advanced acquisition technology, which
     includes several sophisticated custom components, enables its digital
     oscilloscopes to make measurements at high sample rates. The Company's
     Model 9362 offers sample rates of up to 10 GS/s, which the Company
     believes is the highest sample rate available to date.
 
  .  LONG RECORD LENGTHS. The Company's advanced memory architecture, which
     includes several sophisticated custom components, enables its digital
     oscilloscope products to have long record capability. The Company's
     Models 9384 and LC574 offer record lengths of up to 8 million sample
     points at 4 GS/s, which the Company believes is the longest record
     length available to date.
 
  .  POWERFUL PROCESSING CAPABILITY. The Company's multiprocessor
     architecture in each of its LC models combines a Motorola PowerPC main
     processor with custom processors designed by the Company. The
     combination of this advanced multiprocessing technology with the
     Company's patented data-compaction techniques enables the rapid and
     accurate display of long signals and the performance of complex
     analyses.
 
  .  SOPHISTICATED ANALYSIS SOFTWARE. The Company's analysis software
     options, available either at the time of purchase or as aftermarket
     upgrades, provide a wide range of capabilities customized for specific
     end-user applications. By customizing its analysis software, the Company
     believes that it can provide a total solution to a particular customer's
     measurement and analysis requirements.
 
                                      28
<PAGE>
 
  The Company believes that the high sample rates, long record lengths and
powerful hardware and software processing capabilities offered by its various
digital oscilloscope products position it to serve industries, such as the
data storage and communications industries, that require the ability to
measure long, high-speed complex data streams. The Company believes that its
ability to offer digital oscilloscope customers products with these advantages
at what it believes are competitive prices permits it to compete favorably in
its target market segment.
 
STRATEGY
 
  The Company's first business objective is to become a leading supplier of
high-performance digital oscilloscopes. The Company's second business
objective is to participate in broader markets by the use, directly and
through licensing and other arrangements with other manufacturers, of LeCroy's
core acquisition technology in dedicated signal analyzers. The Company is
pursuing the following strategies to achieve these objectives:
 
  .  EXTEND HIGH-PERFORMANCE ACQUISITION TECHNOLOGY. The high-performance
     acquisition technology that the Company originally developed in the
     technically demanding HEP market and its continuing investment in
     research and development have enabled it to develop two families of
     high-performance digital oscilloscope products, certain models of which
     feature what the Company believes is the highest sample rate, and others
     the longest record length, available to date. The Company intends to
     continue to allocate significant resources to extending these
     performance advantages.
 
  .  TARGET HIGH-GROWTH INDUSTRIES WITH SOLUTION-FOCUSED OSCILLOSCOPES. The
     Company's experience with users in certain industries has shown that
     adding special analysis and processing capabilities to its digital
     oscilloscopes permits it to offer total solutions for special data
     measurement and analysis problems. For example, the Company has
     developed digital oscilloscopes targeted at the particular data
     measurement and analysis problems of the data storage industry. The
     Company believes that this strategy was a significant factor in the
     growth of its sales to this industry, which accounted for approximately
     18% of the Company's revenues in its fiscal year ended June 30, 1996.
     The Company recently introduced solution-focused oscilloscopes for the
     optical recording and telecommunications industries. The Company intends
     to target other high growth industries that require solution-focused
     oscilloscopes.
 
  .  LEVERAGE CORE TECHNOLOGY INTO NEW PRODUCT MARKETS. The Company believes
     that it is well positioned to leverage its core acquisition technology
     to develop dedicated signal analyzers for broader markets. The Company
     has entered into an agreement to sell certain proprietary chip sets to
     Guzik Technical Enterprises for use in dedicated instruments for data
     storage devices, such as disk drives, and their components. The Company
     has also entered into an agreement with Fluke Corporation under which
     the Company has licensed Fluke to use LeCroy technology in certain
     handheld scopemeters and low-end digital oscilloscopes. The Company also
     believes that market opportunities for its signal analyzer products
     include the networking and telecommunications industries, and the
     Company is currently in the development stage with respect to a LAN
     monitor product that would analyze electronic signals in communications
     networks in order to provide better monitoring and failure-diagnosis
     capabilities than can be achieved using existing products. In connection
     with these initiatives, the Company expects to incur continuing research
     and development and engineering expenses.
 
  There can be no assurance that the Company will be successful in
implementing its strategies, including whether it will be able to leverage its
core technologies into new product markets.

  Most of the models in the table above are available in several
configurations offering varying record lengths. The "x" suffix used in the
table above denotes a particular product number that is based on the product's
configuration. Taking into account all available configurations, the Company
offers over 30 different products in the 9300 series and LC series.
 
  The Company believes that the following features give its 9300 series and LC
series products one of the best user interfaces in the digital oscilloscope
market:
 
  . Large, high-resolution amber monochrome or color display, organized in a
    manner that facilitates easy readout and analysis of displayed data.
 
  . User-friendly control panel.
 
  . Main processor with up to 64 MB of random access memory.
 
  . Flexible options for data storage (floppy disk, PCMCIA memory card,
    PCMCIA removable hard disk).
 
  .Optional built-in printer that allows users to produce a print-out of the
  display at the touch of a button.
 
                                      30
<PAGE>
 
  . A standard general-purpose interface bus ("GPIB") that enables the
    digital oscilloscope to be part of a measurement and analysis system that
    uses other GPIB-compatible instruments.
 
  As part of its strategy to focus on its 9300 series and LC series products,
the Company is phasing out its other digital oscilloscope product offerings.
The Company is continuing to sell its current inventory of these products,
sales of which accounted for less than 10% of the Company's total revenues for
the fiscal year ended June 30, 1996.
 
  The Company offers its customers a wide array of post-sale upgrades of
important components, such as memory, processor and analysis software, as well
as optional features such as mass storage capability and built-in printers.
These product upgrades and options allow the Company's customers to add
performance and features to adapt their digital oscilloscopes to new
measurement and analysis requirements as they arise, which the Company
believes reduces the risk of product obsolescence to a certain degree.
 
  To provide its digital oscilloscope customers with what it believes are
total solutions to their data measurement and analysis problems, the Company
manufactures and sells a complementary line of signal source products that can
create input signals so that an electronic circuit can be evaluated under
controlled conditions. Using a digital oscilloscope, an engineer can analyze
the shape of the signal within the circuit, compare it to the shape of the
"ideal" input signal generated by the signal source and thereby identify
problems in the circuit. The Company's primary signal source products are
arbitrary waveform generators that allow the user to fully program the shape
of the signals generated. For example, an arbitrary waveform generator can be
programmed to produce signals that simulate those produced by a hard disk
drive head. Its principal arbitrary waveform generator is its Model LW4xx, the
list price of which is approximately $19,000. The Company has focused all its
development resources on signal analysis products and is no longer investing
in signal source products.
 
  Sales of digital oscilloscopes and related products grew from approximately
75% to approximately 89% of the Company's total revenues from fiscal 1994 to
the six months ended December 31, 1996. Sales of products in the Company's
9300 series and LC series (including sales of products in the 9400 series, the
predecessor to the 9300 series) grew from approximately 58% to approximately
85% of the Company's total revenues in those fiscal periods.
 
  The following are examples of specific applications involving the Company's
9300 and LC series digital oscilloscope product families:
 
  . DATA STORAGE--The computer disk drive industry is continually seeking to
    apply advanced magnetic storage technology to increase data density and
    reduce access time. Design engineers in this field require digital
    oscilloscopes with high sample rates and long record lengths. The Company
    believes that its Model 9384L and Model LC574L digital oscilloscopes,
    which feature a maximum sample rate of 4 GS/s and a maximum record length
    of 8,000,000 sample points, are well suited to such applications. In
    addition to providing digital oscilloscopes that meet the disk drive
    industry's requirements for high sample rates and long record lengths,
    the Company has worked closely with customers in this industry to develop
    specialized processing software that incorporates advanced algorithms
    designed specifically for their particular measurement and analysis
    requirements. The Company believes that the combination of its high-
    performance data-acquisition technology with this specialized processing
    capability has been a significant factor in the growth of its sales to
    this industry.
 
  . CELLULAR TELEPHONES/PAGERS--In contrast to many other applications, the
    design of cellular telephones and pagers does not require digital
    oscilloscopes with high bandwidths or sample rates. This is due to the
    relatively longer and slower electronic signals associated with these
    products. It is therefore important that digital oscilloscopes for these
    applications have long record lengths and the ability to display the
    captured data in a meaningful and usable format. The Company believes
    that its Model 9314L digital oscilloscope is particularly well suited to
    such applications. The Model 9314L has a medium bandwidth and sample
    rate, but features a maximum record length of 1,000,000 sample points. In
    addition, the Model
 
                                      31
<PAGE>
 
   9314L has the ability to simultaneously display the entire signal as well
   as an enlarged or "zoomed" view of a portion of the signal.
 
  . LASERS--A typical laser pulse has a duration on the order of two
    billionths of a second. To capture and analyze the shape of a laser
    pulse, a digital oscilloscope must make measurements of its amplitude
    many times during this period. The Company believes that its Model 9362
    is well suited to this application as it has the capability to make
    precise measurements at the rate of ten billion per second, therefore
    permitting this oscilloscope to capture accurately the shape of the laser
    pulse so that it can be analyzed.
 
  Embedded Signal Analyzers. In February 1997, the Company entered into an
agreement to sell certain proprietary chip sets to Guzik Technical Enterprises
for use in dedicated instruments for data storage devices, such as disk
drives, and their components. Subject to certain minimum purchase
requirements, Guzik's rights in these areas are exclusive and preclude the
Company from selling products or licensing its technology to others for use in
these areas. Under the agreement with Guzik, the Company received upon
execution $1.0 million in fees and anticipates receiving over the next nine
months an aggregate of $1.0 million in fees upon delivery of certain
prototypes to Guzik. In addition, Guzik is required to purchase at least
$500,000 worth of chip sets. The Company also has entered into an agreement
with Fluke Corporation under which the Company has licensed Fluke to use
LeCroy technology in certain handheld scopemeters and low-end digital
oscilloscopes. Subject to certain minimum royalty requirements, Fluke's rights
in the handheld scopemeter area are exclusive and preclude the Company from
selling handheld scopemeters or licensing others to use LeCroy technology in
such products. Pursuant to this agreement, the Company is entitled to the
payment of certain royalties commencing in fiscal 1999. See "--Strategy."
 
  HEP Products. A typical HEP experiment consists of a large assembly of
electronics that measures particle energy and speed from up to many hundreds
of thousands of particle detectors. These measurements are used to identify
individual particles and to study their interactions.
 
  The Company's HEP product offerings consist of an extensive range of modular
products. These products include analog-to-digital converters, which measure
particle energy and time-to-digital converters which measure particle speed.
The modular nature of these products enables experimenters to select products
from the Company's HEP product catalog and combine them in a configuration
that provides an overall solution to their particular data measurement and
analysis problems.
 
  Sales of HEP products (including digitizers) accounted for approximately
21%, 15%, 11% and 7% of the Company's total revenues in its fiscal years ended
June 30, 1994, 1995 and 1996 and the six months ended December 31, 1996,
respectively.
 
  Service and Aftermarket Products. The Company provides aftermarket support,
repair, maintenance and recalibration of installed Company products, as well
as installation of a variety of post-sale upgrades and optional features. The
Company maintains three major field service centers in Chestnut Ridge, New
York (located at the Company's corporate headquarters), Heidelberg, Germany
and Osaka, Japan. Sophisticated service on certain key components of the
Company's digital oscilloscope products, including on its printed circuit
boards, is performed only at the Company's manufacturing facilities in Geneva,
Switzerland and Chestnut Ridge, New York. The Company warrants its digital
oscilloscopes for three years (two years for digital oscilloscopes sold prior
to December 1, 1994), signal source products from one to five years, and HEP
products for one year.
 
CUSTOMERS
 
  During the three fiscal years ended June 30, 1996 and six months ended
December 31, 1996, the Company shipped a total of approximately 16,700 digital
oscilloscopes worldwide. The largest group of users of the Company's digital
oscilloscopes are electronic product designers and test engineers. Researchers
in many scientific disciplines including high-energy physics, medicine,
geology, ultrasound and mechanics also use the Company's digital
oscilloscopes.
 
  No single customer accounted for more than 4% of the Company's sales in the
fiscal years ended June 30, 1995 and 1996. The Company's top 25 customers,
each of which purchased more than $375,000 of products,
 
                                      32

SALES, MARKETING AND DISTRIBUTION
 
  The Company maintains a direct sales force of highly trained, technically
sophisticated sales engineers who are knowledgeable in the use of signal
analyzers in general and the features and advantages of the Company's products
in particular. In addition, particularly because of the Company's focus on
high-performance digital oscilloscopes, the Company believes that its sales
engineers are skilled in performing product demonstrations for current and
prospective customers. The Company believes it has a competitive advantage in
sales situations in which its sales engineers have the opportunity to
demonstrate the advantages of the Company's digital oscilloscopes;
accordingly, such demonstrations are an integral part of the Company's sales
strategy.
 
  The Company sells its digital oscilloscope products through its own direct
sales force in the United States, Europe and Japan with regional sales
headquarters located in Chestnut Ridge, New York, Heidelberg, Germany and
Osaka, Japan. As of December 31, 1996, the Company's direct sales force
consisted of 65 sales engineers directed by eight regional managers worldwide.
The Company is currently in the process of evaluating the integration of its
HEP sales force into its digital oscilloscope sales force. The Company also
uses manufacturer's representatives in support of its direct selling efforts
and in territories where the sales potential does not currently justify the
maintenance of a direct sales force. In addition, in Japan the Company
maintains a strategic alliance with Iwatsu Electric Co. Ltd., a Japanese
communications and test-and-measurement company that sells and distributes
some of the Company's products under the "Iwatsu/LeCroy" and "Iwatsu" labels.
 
  The Company recently has reorganized and expanded its marketing department
to further focus its efforts towards the market for high performance signal
analyzers. In connection with that effort, the Company hired a new Vice
President of Marketing in fiscal 1996. See "Management."
 
  In order to raise market awareness of its products, the Company advertises
in trade publications, distributes promotional materials, conducts marketing
programs and seminars, issues press releases regarding new products, publishes
technical articles and participates in industry trade shows and conferences.
 
RESEARCH AND DEVELOPMENT
 
  The Company believes that as a result of what it views as a continuing shift
in technology towards higher speed digital signals containing more complex
data, users of signal analyzer products will continue to demand higher
bandwidths, higher sample rates, longer record lengths and more powerful
processing capabilities. The
 
                                      33
<PAGE>
 
primary objective of the Company's research and development program is to
extend its high performance technology in order to satisfy this demand, while
maintaining ease-of-use qualities and favorable price-to-performance ratios.
There can be no assurance that the Company will achieve this objective.
 
  The Company is continuing to develop its sampling, data storage and
processing technologies using advanced integrated circuit techniques, and is
also working to improve its existing digital oscilloscope platform to provide
display enhancements, higher speed data processing and a broader range of
application-specific hardware and software options.
 
  The Company intends to use its core acquisition technology to develop
dedicated signal analyzers for broader markets. The Company believes that
possible market opportunities for such products include the networking and
communications industries. The Company is currently in the development stage
with respect to a LAN monitor product that would analyze electronic signals in
communications networks in order to provide better monitoring and failure-
diagnosis capabilities than can be achieved using existing products. There can
be no assurance that the Company will be successful in developing such a
signal analyzer.
 
  The Company conducts research and development activities in both its Geneva,
Switzerland and Chestnut Ridge, New York facilities. The Company's research
and development expenses, which are expensed as incurred, were approximately
$8.8 million, $10.3 million, $12.6 million and $7.3 million in its fiscal
years ended June 30, 1994, 1995 and 1996 and for the six months ended December
31, 1996, respectively, which expenses represented 13.7%, 12.5%, 12.5% and
13.2% of total revenues, respectively, for such fiscal periods. The Company
intends to continue to invest approximately 12% to 14% of revenues in its
research and development efforts.
 
MANUFACTURING AND SUPPLIES
 
  Prior to the Company's decision to concentrate on high-performance digital
oscilloscopes, the Company's digital oscilloscopes and related products were
manufactured at the Company's facilities in Geneva, Switzerland and Chestnut
Ridge, New York, with HEP products also manufactured at the Chestnut Ridge
facility. Following that decision, and until the first quarter of fiscal 1996,
all 9300 series digital oscilloscopes were manufactured at the Company's
Geneva facility, with the Chestnut Ridge facility principally manufacturing
HEP products, signal source products and hybrid and chip-on-board microcircuit
assemblies for Geneva's digital oscilloscope production. While continuing to
manufacture models in its 9300 series and LC series at its Geneva
manufacturing facility, the Company increasingly has been manufacturing such
products in its Chestnut Ridge facility.
 
  This shift in manufacturing has been undertaken for a variety of reasons,
including greater utilization of the Chestnut Ridge facility in light of the
reduced volume in HEP sales and an increase in the volume of U.S. sales, an
expected reduction in certain customs duties resulting from shipping parts
rather than completed units to the United States from Geneva, closer alignment
of manufacturing and development facilities and, to the extent that the
Company is able to source components in the United States for models assembled
and sold in the United States, better currency matching of revenues and
related costs. The Company has established United States vendors as sources
for certain components, including printed circuit board assemblies, that had
previously been shipped from its Geneva facility to its Chestnut Ridge
facility. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
  The Company obtains certain parts, components and sub-assemblies from single
sources. This has particularly been the case with several key integrated
circuits made by certain single source suppliers (Motorola, Philips, TRW and
LSI Logic). The Company believes that, for integrated circuits in particular,
alternative sources of supply would be difficult to develop over a short
period of time. An interruption in supply or an increase in price for its
parts, components and sub-assemblies would have a material adverse affect on
the Company's business, results of operations and financial condition.
 
 
                                      34
<PAGE>
 
  As of December 31, 1996, the Company's Geneva facility employed 42
manufacturing employees in an area devoted to such tasks of approximately
14,000 square feet and its Chestnut Ridge facility employed 101 manufacturing
employees in an area devoted to such tasks of approximately 26,000 square
feet.
 
BACKLOG
 
  The Company's backlog of unshipped customer orders was approximately $8.5
million, $8.0 million and $7.9 million at June 30, 1995, June 30, 1996 and
December 31, 1996, respectively. Customers may cancel orders at any time. The
Company believes that its level of backlog at any particular time is not
necessarily indicative of future operating performance of the Company.
 
TAX AGREEMENT WITH CANTON OF GENEVA
 
  Currently, the Company's Swiss subsidiary operates under a tax agreement
with the Canton of Geneva under which its profits are taxed at different rates
depending on the geographic location of the customers to whom sales are made.
Profits from sales to customers in Switzerland (including CERN) are taxed at a
35% tax rate, while profits from sales to other customers are taxed at a
preferential tax rate. For the fiscal year ended June 30, 1996, this
arrangement resulted in an effective tax rate of 15% for the Company's Swiss
subsidiary. This agreement will expire in the fiscal year ended June 30, 2000.
 
FOREIGN CURRENCY EXCHANGE
 
  The Company has manufacturing facilities in both the United States and
Switzerland, purchases parts, components and sub-assemblies from suppliers
around the world in a variety of currencies and sells its products around the
world in a variety of currencies. As a consequence, the Company is exposed to
risks from fluctuations in foreign currency exchange rates with respect to a
number of currencies, changes in government policies and legal and regulatory
requirements, political instability, transportation delays and the imposition
of tariffs and export controls. Among the more significant potential risks to
the Company of relative fluctuations in foreign currency exchange rates is the
relationship among and between the United States dollar, Swiss franc and
Japanese yen, and, to a lesser extent, the German deutschemark, British pound,
French franc and Italian lira. During the fiscal year ended June 30, 1996 and
the first half of fiscal 1997, approximately half of the Company's revenues
and half of its costs and expenses were denominated in currencies other than
the United States dollars. Local currency expenses resulting from
manufacturing and the worldwide sourcing of parts, components and sub-
assemblies are not generally offset by related local currency revenues, if
any. The Company seeks to mitigate to some degree its exposure to foreign
currency exchange rate fluctuations by borrowing under its multicurrency
revolving credit facility in circumstances in which it is exposed to
significant local currency receivables. The Company does not attempt to reduce
its foreign currency exchange risks by entering into other foreign currency
management programs or hedging transactions and has no plans to do so in the
near term. As a consequence, there can be no assurance that the Company's
results of operations will not be adversely effected by fluctuations in
foreign currency exchange rates in the future, as a result of mismatches
between local currency revenues and expenses, the translation of foreign
currencies into the United States dollar, the Company's financial reporting
currency, or otherwise. Moreover, fluctuations in exchange rates could affect
demand for the Company's products. During the fiscal years ended June 30, 1994
and 1995, foreign currency exchange losses amounted to $512,000 and $684,000,
respectively. During the fiscal year ended June 30, 1996 and the first six
months of fiscal 1997, the Company reported foreign currency exchange gains of
$539,000 and $609,000, respectively. Based on exchange rates as of the date of
this Prospectus, the Company expects that its revenues for the third quarter
of fiscal 1997 will continue to be adversely impacted by the strength of the
U.S. dollar. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
COMPETITION
 
  The market for signal analyzers is highly competitive and characterized by
rapid and continual advances in technology. Prime Data estimates that the four
largest suppliers of digital oscilloscopes, exclusive of handheld
 
                                      35
<PAGE>
 
models, and their approximate respective market shares for calendar year 1996
were Tektronix with 42.5%, Hewlett-Packard Company with 18.1%, LeCroy with
12.4% and Fluke Corporation with 4.9%. Some of the Company's principal
competitors have substantially greater sales and marketing, development and
financial resources than the Company. The Company believes that each of these
companies offers a wide range of products that attempt to address most
segments of the digital oscilloscope market.
 
  The Company believes that the principal bases of competition in the signal
analyzer market are a product's performance (bandwidth, sample rate, record
length and processing power), its price and quality, the vendor's name
recognition, reputation, color displays, product availability and the
availability and quality of post-sale support. The Company also believes that
its success will depend in part on its ability to maintain and develop the
advanced technology used in its signal analyzer products and its ability to
offer high-performance products at a favorable price-to-performance ratio. The
Company believes that it currently competes effectively with respect to each
of the principal bases of competition in the signal analyzer market in the
general price range ($5,000 to $37,500) in which its digital oscilloscopes are
focused and that it will be able to continue to do so, but there can be no
assurance that this is or will be the case.
 
  The Company believes that its principal competition in the HEP market comes
from its customers themselves, who are technically sophisticated and
frequently choose to construct their own measurement and analysis systems. The
Company also believes that the rest of this market is highly fragmented and
consists of a number of small firms, no one of which commands a significant
market share.
 
INTELLECTUAL PROPERTY RIGHTS
 
  The Company currently relies on a combination of patents, trade secrets,
technical expertise and continuing technological research and development to
establish and protect proprietary rights in its products. The Company
believes, however, that because of the rapid pace of change and advancement in
digital oscilloscope technology, legal intellectual property protection is and
will continue to be a less significant factor in the Company's success than
the Company's core competency in converting electronic signals to digital form
and the experience and expertise of its personnel.
 
  The Company protects significant technologies, products and processes that
it considers important to its business by, among other things, filing
applications for patent protection. As of December 31, 1996, the Company held
a total of twelve United States patents expiring in the years from 2000 to
2012. The Company also holds four foreign patents. The Company has pending
applications for eight additional United States patents and for five
additional foreign patents. The patent positions of high-technology companies
such as the Company are uncertain, however, and involve complex legal issues
and factual questions. There can be no assurance that any of the Company's
pending or future applications will result in issued patents or that any
issued patents will provide the Company with adequate protection of the
covered technologies, products or processes. Moreover, the laws of foreign
countries in which the Company's products are or may be developed,
manufactured or sold may not protect the Company's intellectual property and
other proprietary rights to the same extent as the laws of the United States.
 
  Although the Company believes that its products and technologies do not
infringe the proprietary rights of third parties, there can be no assurance
that third parties will not assert claims against the Company based on the
infringement or alleged infringement of any such rights. Such claims are
typically costly to defend, regardless of the legal outcome. There can be no
assurance that the Company would prevail with respect to any such claim, or
that a license to third-party rights, if needed, would be available on
acceptable terms. In any event, patent and proprietary rights litigation can
be extremely protracted and expensive.
 
  In February 1994, the Company settled litigation with Tektronix involving
allegations that the Company's digital oscilloscope products infringed patents
held by Tektronix. As part of the settlement, the Company entered into a
license agreement with respect to such patents. Pursuant to the license
agreement the Company made an initial payment of approximately $1.5 million.
In addition, the Company is required to make future royalty
 
                                      36
<PAGE>
 
payments in a minimum aggregate amount of $3.5 million over ten years ending
June 30, 2004 and may be required to make up to an additional $3.5 million in
contingent royalty payments depending on its sales of certain products in
certain territories over the life of the patents. Royalty expense was
approximately $781,000, $963,000 and $550,000 in fiscal 1995 and 1996 and the
first six months of fiscal 1997, respectively. The settlement agreement
provides that Tektronix may terminate the license in the event that the
Company acquires 20% or more of the stock of, or a controlling interest in,
any of a number of specified companies participating in the oscilloscope
market or any of their respective affiliates (each, a "Restricted Company") or
a Restricted Company acquires 20% or more of the stock of, or a controlling
interest in, the Company or an affiliate of the Company, or any attempt to
transfer the Tektronix license to a Restricted Company is made. This provision
of the settlement could preclude the Company from making an investment in or
acquisition of such companies, and it also could discourage such companies or
another third party from attempting to acquire control of the Company or limit
the price that such a third party might be willing to pay for the Common
Stock. In addition, this provision could limit the price that investors might
be willing to pay in the future for the Common Stock.
 
EMPLOYEES
 
  As of December 31, 1996, the Company had 504 employees, of whom 285 work in
the Company's Chestnut Ridge facility, 120 work in the Company's Geneva
facility, and the remainder work in various other Company offices around the
world. None of the Company's employees is represented by a labor union and the
Company has not experienced any work stoppages. The Company believes that its
employee relations are generally satisfactory. A majority of the Company's
senior managers has over five years of service with the Company.
 
  Competition for qualified personnel in the Company's industry is intense.
There can be no assurance that the Company will be successful in retaining its
key employees or in attracting and retaining additional qualified personnel.
See "Risk Factors--Dependence on Key Employees."
 
FACILITIES
 
  The Company's executive offices and its domestic manufacturing facility are
located in a two-story, approximately 88,000 square foot building in Chestnut
Ridge, New York that is owned by the Company. The Company also leases a three-
story office and manufacturing building of approximately 44,000 square feet in
Geneva, Switzerland pursuant to a lease expiring December 31, 2004. In
addition, the Company leases other offices around the world on a short-term
basis to support its local sales and service operations. The Company believes
that its existing facilities and offices are adequate for its current and
anticipated needs.
 
REGULATION
 
  As the Company manufactures its products in the United States and
Switzerland, and sells its products and purchases parts, components and sub-
assemblies in a number of countries, the Company is subject to legal and
regulatory requirements, particularly the imposition of tariffs, customs and
export controls, in a variety of countries. In addition, the export of digital
oscilloscopes from both the United States and Switzerland is subject to
regulation under the Treaty for Nuclear Non-Proliferation by such countries.
 
LEGAL PROCEEDINGS
 
  The Company is not currently party to any material legal proceedings.

REPURCHASE BY THE COMPANY OF SHARES FROM THE ESOT
 
  The Company is in the process of offering to beneficial owners of vested
shares of Common Stock in the ESOT the opportunity for the Company to
repurchase from the ESOT for the account of such persons such vested shares at
a price per share equal to the initial offering price of the shares of Common
Stock offered to the public in the Offering. The Company will use a portion of
the net proceeds of the Offering to repay indebtedness incurred in connection
with the purchase of the ESOT shares. The exact number of shares to be
repurchased from the ESOT will be determined shortly before the Offering and
is currently estimated at approximately 350,000 shares. See "Use of Proceeds."
 
                                      42

  The assets of the ESOT are invested primarily in Common Stock of the
Company. Cole Taylor Bank is currently the trustee of the ESOT (the
"Trustee"). The Trustee has the authority to manage and control the ESOT,
including the investment and administration of ESOT assets. Following this
Offering and the repurchase of shares of Common Stock from the ESOT, the ESOT
will own approximately 223,943 shares of Common Stock of the Company
(approximately 3.4% of the shares to be outstanding after the Offering). See
"Use of Proceeds."

                         DESCRIPTION OF CAPITAL STOCK
 
  The authorized capital stock of the Company consists of 45,000,000 shares of
Common Stock, par value $.01 per share, and 5,000,000 shares of Preferred
Stock, par value $.01 per share.
 
COMMON STOCK
 
  As of February 19, 1997, there were 5,660,133 shares of Common Stock
outstanding and held of record by 203 stockholders. Based upon the number of
shares of Common Stock outstanding as of that date and giving effect to the
issuance of the 658,838 shares of Common Stock offered hereby, the issuance of
583,011 shares through the exercise of stock warrants, reduced by the
repurchase of approximately 350,000 shares from the ESOT, there will be
6,551,982 shares of Common Stock outstanding upon the closing of this
Offering.
 
  Holders of Common Stock are entitled to one vote for each share held on all
matters submitted to a vote of stockholders and do not have cumulative voting
rights. Accordingly, holders of a majority of the shares of Common Stock
entitled to vote in any election of directors may elect all of the directors
standing for election. Holders of Common Stock are entitled to receive ratably
such dividends, if any, as may be declared by the Board of Directors out of
funds legally available therefor, subject to any preferential dividend rights
of outstanding Preferred Stock. Upon the liquidation, dissolution or winding
up of the Company, the holders of Common Stock are entitled to receive ratably
the net assets of the Company available after the payment of all debts and
other liabilities, subject to the prior rights of any outstanding Preferred
Stock. Holders of the Common Stock have no preemptive, subscription,
redemption or conversion rights. The outstanding shares of Common Stock are,
and the shares offered by the Company in the Offering will be, when issued and
paid for, fully paid and nonassessable. The rights, preferences and privileges
of holders of Common Stock are subject to, and may be adversely affected by,
the rights of the holders of shares of any series of Preferred Stock that the
Company may designate and issue in the future. As of the date hereof this
Offering, there are no shares of Preferred Stock outstanding.
 
PREFERRED STOCK
 
  The Board of Directors is authorized, subject to certain limitations
prescribed by law, without further stockholder approval, from time to time to
issue up to an aggregate of 5,000,000 shares of Preferred Stock in one or more
series and to fix or alter the designations, preferences and rights, and any
qualifications, limitations or restrictions thereof, of the shares of each
such series, including the number of shares constituting any such series and
the dividend rights, dividend rates, conversion rights, voting rights, terms
of redemption (including sinking fund provisions), redemption price or prices
and liquidation preferences thereof. The issuance of Preferred Stock may have
the effect of delaying, deferring or preventing a change of control of the
Company. The Company has no present plans to issue any shares of Preferred
Stock.
 
DELAWARE LAW AND CERTAIN CHARTER AND BY-LAW PROVISIONS
 
  The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law (the "DGCL"). Subject to certain exceptions, Section
203 prohibits a publicly held Delaware corporation from engaging in a
"business combination" with an "interested stockholder" for a period of three
years after the date of the transaction in which the person became an
interested stockholder, unless the interested stockholder attained such status
with the approval of the Board of Directors or unless the business combination
is approved in a prescribed manner. A "business combination" includes certain
mergers, asset sales and other transactions resulting in a financial benefit
to the interested stockholder. Subject to certain exceptions, an "interested
stockholder" is a person who, together with his or her affiliates and
associates, owns, or owned within three years prior, 15% or more of the
corporation's voting stock.
 
  The Company's Certificate of Incorporation (the "Charter") and Amended and
Restated By-Laws (the "By-Laws") provide for the division of the Board of
Directors into three classes, as nearly equal in size as
 
                                      44
<PAGE>
 
possible, with staggered three-year terms. See "Management--Executive Officers
and Directors." Any director may be removed only for cause by the vote of a
majority of the shares entitled to vote for the election of directors.
 
  The Company's By-Laws provide that for nominations for the Board of
Directors or for other business to be properly brought by a stockholder before
a meeting of stockholders, the stockholder must first have given timely notice
thereof in writing to the Secretary of the Company. To be timely, a notice of
nominations or other business to be brought before an annual meeting must be
delivered not less than 120 days nor more than 150 days prior to the first
anniversary of the date of the proxy statement delivered to stockholders in
connection with the preceding year's annual meeting or, if the date of the
annual meeting is more than 30 days before or more than 60 days after such
anniversary, or if no proxy statement was delivered to stockholders in
connection with the preceding year's annual meeting, such notice must be
delivered not earlier than 90 days prior to such annual meeting and not later
than the later of (i) 60 days prior to the annual meeting or (ii) 10 days
following the date on which public announcement of the date of such annual
meeting is first made by the Company. With respect to special meetings, notice
must generally be delivered not more than 90 days prior to such meeting and
not later than the later of 60 days prior to such meeting or 10 days following
the day on which public announcement of such meeting is first made by the
Company. The notice must contain, among other things, certain information
about the stockholder delivering the notice and, as applicable, background
information about each nominee or a description of the proposed business to be
brought before the meeting.
 
  The Charter empowers the Board of Directors, when considering a tender offer
or merger or acquisition proposal, to take into account factors in addition to
potential economic benefits to stockholders. Such factors may include (i)
comparison of the proposed consideration to be received by stockholders in
relation to the then current market price of the Company's capital stock, the
estimated current value of the Company in a freely negotiated transaction and
the estimated future value of the Company as an independent entity, and (ii)
the impact of such a transaction on the employees, suppliers and customers of
the Company and its effect on the communities in which the Company operates.
 
  The foregoing provisions could have the effect of making it more difficult
for a third party to acquire, or of discouraging a third party from acquiring,
control of the Company.
 
  The Charter provides that any action required or permitted to be taken by
the stockholders of the Company may be taken only at duly called annual or
special meeting of the stockholders, and that special meetings may be called
only by the Chairman of the Board of Directors, a majority of the Board of
Directors or the President of the Company. These provisions could have the
effect of delaying until the next annual stockholders meeting stockholder
actions that are favored by the holders of a majority of the outstanding
voting securities of the Company. These provisions may also discourage another
person or entity from making a tender offer for the Common Stock, because such
person or entity, even if it acquired a majority of the outstanding voting
securities of the Company, would be able to take action as a stockholder (such
as electing new directors or approving a merger) only at a duly called
stockholders meeting, and not by written consent.
 
  The DGCL provides that the affirmative vote of a majority of the shares
entitled to vote on any matter is required to amend a corporation's
certificate of incorporation or by-laws, unless the corporation's certificate
of incorporation or by-laws, as the case may be, requires a greater
percentage. The Charter requires the affirmative vote of the holders of at
least 67% of the outstanding voting stock of the Company to amend or repeal
any of the foregoing Charter provisions, or to reduce the number of authorized
shares of Common Stock and Preferred Stock. Such 67% vote is also required to
amend or repeal any of the foregoing By-Law provisions. The By-Laws may also
be amended or repealed by a majority vote of the Board of Directors. Such 67%
stockholder vote would be in addition to any separate class vote that might in
the future be required pursuant to the terms of any Preferred Stock that might
be outstanding at the time any such amendments are submitted to stockholders.

Dispute Settlement and License Agreement."

LIMITATION OF LIABILITY AND INDEMNIFICATION
 
  The Charter contains certain provisions permitted under the DGCL relating to
the liability of directors. These provisions eliminate a director's personal
liability for monetary damages resulting from a breach of fiduciary duty,
except in certain circumstances involving certain wrongful acts, such as the
breach of a director's duty of loyalty or acts or omissions that involve
intentional misconduct or a knowing violation of law. These provisions do not
limit or eliminate the rights of the Company or any stockholder to seek non-
monetary relief, such as an injunction or rescission, in the event of a breach
of a director's fiduciary duty. These provisions will not alter a director's
liability under federal securities laws. The Company's Charter and By-Laws
also contain provisions indemnifying the directors and officers of the Company
to the fullest extent permitted by the DGCL. The Company believes that these
provisions will assist the Company in attracting and retaining qualified
individuals to serve as directors.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Common Stock is The First National
Bank of Boston.

</TABLE>
 
  The Company and the Selling Stockholders are obligated to sell, and the
Underwriters are obligated to purchase, all of the shares of Common Stock
offered hereby if any are purchased.
 
  The Underwriters, through their Representatives, have advised the Company
and the Selling Stockholders that they propose to offer the Common Stock
initially at the public offering price set forth on the cover page of this
Prospectus; that the Underwriters may allow to selected dealers a concession
of $    per share; and that such dealers may reallow a concession of $    per
share to certain other dealers. After the Offering, the offering price and the
concessions may be changed by the Representatives.
 
  The Company has granted to the Underwriters an over-allotment option,
exercisable for 30 days from the date of this Prospectus, to purchase up to
300,000 additional shares of Common Stock at the public offering price, less
underwriting discounts, as set forth on the cover page of this Prospectus. The
Underwriters may exercise such option solely for the purpose of covering any
over-allotments incurred in the sale of the shares of Common Stock offered
hereby. To the extent such option to purchase is exercised, each Underwriter
will become obligated, subject to certain conditions, to purchase
approximately the same percentage of such additional shares as the number set
forth next to such Underwriter's name in the preceding table bears to
2,000,000.
 
  The Company and the Selling Stockholders have agreed to indemnify the
several Underwriters or contribute to losses arising out of certain
liabilities, including liabilities under the Securities Act, as amended.
 
  The Company, its officers and directors and certain stockholders of the
Company who, upon completion of the Offering will own in the aggregate of
1,064,865 shares of Common Stock, have agreed not to, directly or indirectly,
without the prior written consent of Prudential Securities Incorporated, on
behalf of the Underwriters, offer, sell, offer to sell, contract to sell,
pledge, grant any option to purchase or otherwise sell or dispose (or announce
any offer, sale, offer of sale, contract of sale, pledge, grant of any option
to purchase or other sale or disposition) of any shares of Common Stock or
other capital stock of the Company or any securities convertible into, or
exercisable or exchangeable for, any shares of Common Stock or other capital
stock of the Company, or any right to purchase or acquire Common Stock or
other capital stock of the Company, for a period of 90 days from the date of
this Prospectus. Prudential Securities Incorporated may, in its sole
discretion, at any time and without notice, release all or any portion of the
securities subject to such agreements.
 
                                      47
<PAGE>
 
  In connection with the Offering, certain Underwriters and selling group
members (if any) or their respective affiliates who are qualified registered
market makers on the Nasdaq National Market, may engage in passive market
making transactions in the Common Stock on the Nasdaq National Market in
accordance with Rule 103 under Regulation M during the business day prior to
the pricing of the Offering. Such passive market makers must comply with
applicable volume and price limitations and must be identified as such. In
general, a passive market maker must display its bid at a price not in excess
of the highest independent bid for such security; if all independent bids are
lowered below the passive market maker's bid, however, such bid must then be
lowered when certain purchase limits are exceeded.
 
  In connection with the Offering, certain Underwriters and selling group
members (if any) and their respective affiliates may engage in transactions
that stabilize, maintain or otherwise affect the market price of the Common
Stock. Such transactions may include stabilization transactions effected in
accordance with Rule 104 of Regulation M, pursuant to which such persons may
bid for or purchase Common Stock for the purpose of stabilizing its market
price. The Underwriters also may create a short position for the account of
the Underwriters by selling more Common Stock in connection with the Offering
then they are committed to purchase from the Company and the Selling
Stockholders, and in such case may purchase Common Stock in the open market
following completion of the Offering to cover all or a portion of such short
position. The Underwriters may also cover all or a portion of such short
position, up to 300,000 shares of Common Stock, by exercising the
Underwriters' over-allotment option referred to above. In addition, Prudential
Securities Incorporated, on behalf of the Underwriters, may impose "penalty
bids" under contractual arrangements with the Underwriters whereby it may
reclaim from an Underwriter (or any selling group member participating in the
Offering) for the account of the other Underwriters, the selling concession
with respect to Common Stock that is distributed in the Offering but
subsequently purchased for the account of the Underwriters in the open market.
Any of the transactions described in this paragraph may result in the
maintenance of the price of the Common Stock at a level above that which might
otherwise prevail in the open market. None of the transactions described in
this paragraph is required, and, if they are undertaken, they may be
discontinued at any time.

                        REPORT OF INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
LeCroy Corporation
 
  We have audited the accompanying consolidated balance sheets of LeCroy
Corporation as of June 30, 1995 and 1996, and the related consolidated
statements of operations, stockholders' equity and cash flows for each of the
three years in the period ended June 30, 1996. 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 consolidated financial position of LeCroy
Corporation at June 30, 1995 and 1996, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
June 30, 1996 in conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
(INFORMATION AS OF DECEMBER 31, 1996 AND FOR THE SIX MONTHS ENDED DECEMBER 31,
                          1995 AND 1996 IS UNAUDITED)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Basis of Presentation
 
  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
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  The consolidated interim financial information for the six month periods
ended December 31, 1995 and 1996 is unaudited and has been prepared in
accordance with generally accepted accounting principles for interim financial
information and Article 10 of Regulation S-X. Accordingly, it does not include
all of the information and footnotes required by generally accepted accounting
principles for complete financial statements. In the opinion of management,
all adjustments (consisting of normal recurring accruals) considered necessary
for a fair presentation have been included. Operating results for the six
month period ended December 31, 1996 are not necessarily indicative of the
results that may be expected for the year ended June 30, 1997.
 
  Certain amounts in the accompanying unaudited interim consolidated statement
of cash flows for the six months ended December 31, 1995 have been
reclassified to conform to the current presentation.
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of LeCroy
Corporation (the "Company") and its wholly owned subsidiaries. All significant
intercompany balances and transactions have been eliminated. Certain prior
year amounts have been reclassified to conform with the current year.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain estimates
and assumptions that affect the reported amounts in the financial statements
and the accompanying notes. Actual results could differ from those estimates.
 
 Revenue Recognition
 
  Substantially all revenue is recognized when products are shipped or
services are rendered to customers. Revenues from service contracts are
recognized ratably over the contract period.
 
 Fiscal Year Ending Dates
 
  The operations of the U.S. company, LeCroy Corporation, have a fiscal year
end of the Saturday closest to June 30 (July 2, 1994, July 1, 1995, and June
29, 1996). For each of the fiscal years presented, the fiscal year represented
a 52 week period. The majority of foreign subsidiaries have a June 30 fiscal
year end. The consolidated financial statements' year end references are
stated as of June 30.
 
 Cash Equivalents
 
  Cash equivalents represent highly liquid debt instruments with a maturity of
three months or less at the time of purchase. Financial instruments, which
potentially subject the Company to concentrations of credit risk, consist
primarily of short-term deposits in Europe with major banks located in various
cities with investment levels and debt ratings set to limit exposure with any
one institution.

(INFORMATION AS OF DECEMBER 31, 1996 AND FOR THE SIX MONTHS ENDED DECEMBER 31,
                          1995 AND 1996 IS UNAUDITED)
 
 
 Concentration of Credit Risks
 
  The Company manufactures and sells electronic equipment, principally a line
of digital oscilloscopes, to research facilities, governmental agencies and
the test and measurement industry. Sales are to all regions of the United
States as well as to a multitude of foreign countries. The Company performs
periodic credit evaluations of its customers' financial condition. Credit
losses have been minimal and within management's expectations. There is no
significant concentration of the Company's accounts receivable portfolio in
any customer or geographical region that presents a risk to the Company based
on that concentration.
 
 Property and Equipment
 
  Property and equipment are carried at cost. Depreciation and amortization
are provided on the straight-line basis. The estimated useful lives are as
follows:

      <S>                                                             <C>
      Building.......................................................   32 years
      Furniture, machinery and equipment............................. 3-12 years
</TABLE>
 
 Income Taxes
 
  Income taxes are accounted for under Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes." This statement requires that
deferred taxes be established for all temporary differences between book and
tax bases of assets and liabilities, measured using enacted tax rates and laws
that will be in effect when the differences are expected to reverse.
 
  United States income taxes have not been provided on the undistributed net
earnings of foreign subsidiaries which amount approximated $17,700 at June 30,
1996. Determining the tax liability that would arise if these earnings were
remitted is not practicable. The Company plans to reinvest substantially all
of these net earnings in assets located outside of the United States, thus
indefinitely postponing the remittance of such earnings.
 
 Foreign Exchange
 
  The Company's foreign subsidiaries use their local currency as the
functional currency and translate all assets and liabilities at current
exchange rates and all income and expenses at average exchange rates. The
adjustment resulting from this translation is included in a separate component
of stockholders' equity. Gains (losses) in fiscal 1994, 1995 and 1996
resulting from foreign currency transactions approximated $(512), $(684) and
$539, respectively, and are included in other (income) expenses, net.
 
 Warranty
 
  Estimated future warranty obligations related to products are provided by
charges to operations in the period that the related revenue is recognized.
 
 Research and Development
 
  Research and development costs are expensed as incurred.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)
 
(INFORMATION AS OF DECEMBER 31, 1996 AND FOR THE SIX MONTHS ENDED DECEMBER 31,
                          1995 AND 1996 IS UNAUDITED)
 
 
 Per Share Information
 
  Net income (loss) per share is computed based upon the weighted average
number of shares of Common Stock and common share equivalents outstanding
during the periods presented. Common share equivalents result from outstanding
rights, options and warrants to purchase Common Stock and the conversion of
Preferred Stock and are included to the extent dilutive. In accordance with
Securities and Exchange Commission Staff Accounting Bulletin No. 83, shares
issuable upon exercise of stock rights, options and warrants granted during
the twelve months immediately preceding October 5, 1995, the date of the
Company's initial public offering, have been included in the calculation of
the shares used in computing net income (loss) per share as if they were
outstanding for all periods presented prior to the initial public offering
(using the treasury stock method), including loss years where the impact of
the incremental shares is anti-dilutive.
 
 Treasury Stock
 
  The Company delivers treasury shares upon the exercise of stock options and
the issuance of shares from the 1995 Employee Stock Purchase Plan. The
difference between the cost of the treasury shares, on a last-in, first-out
basis, and the exercise price of the option or the cost of shares from the
Employee Stock Purchase Plan is reflected in additional paid-in capital.
 
 Hedging and Related Financial Instruments
 
  The Company utilizes foreign currency based borrowings in an effort to hedge
foreign exchange risks.
 
2. INVENTORIES
 
  Inventories, including demonstration units in finished goods, are stated at
the lower of cost (first-in, first-out method) or market.

  In December 1995, the Company finalized an unsecured $15 million
multicurrency revolving line of credit agreement with several commercial banks
which allows for borrowings in various currencies and provides for interest to
be payable quarterly at the higher of the prime rate, the federal funds rate
(as defined) plus 1/2% or the Eurocurrency Interest Rate (as defined). This
facility replaced a previous secured agreement. As of June 30, 1996 and
December 31, 1996, United States dollar advances were $4,600 and $7,000,
respectively, at 8.25% interest; the carrying amount approximates fair value
based upon market rates. A commitment fee is assessed on the unused line of
credit, payable at the end of each calendar quarter, at a rate of 1/4of 1% per
annum. The credit agreement expires on January 31, 1999. The agreement
contains covenants that include maintaining specified financial ratios and
positive levels of net income and limitations on capital expenditures and
lease obligations.
 
  In October 1995 proceeds received from the Company's initial public offering
were used to repay previously outstanding term loans and subordinated debt. An
extraordinary non-cash charge of $1.3 million of deferred financing costs was
taken resulting from the early extinguishment of this debt.
 
  Interest expense, net included in other (income) expenses, net, was $1,182
in fiscal 1994, $1,528 in fiscal 1995, $672 in fiscal 1996, and $306 in the
six months ended December 31, 1996.
 
  At fiscal year end 1996 the Company had short-term unused lines of credit
aggregating $5,447 for foreign operations.

  Aggregate maturities of the above term debt for each of the years in the
three year period ending June 30, 1999 are $930, $0 and $4,627, respectively.
 
6. CAPITAL STOCK AND OPTION PLANS
 
  On October 5, 1995, the Company completed an initial public offering of
1,500,000 shares of Common Stock for net proceeds of $15.3 million, at which
time 782,609 shares of Series B Preferred Stock and 655,774 shares of Series C
Preferred Stock were converted to Common Stock at the rate of one share for
one share.
 
  On March 28, 1995, in conjunction with the issuance of $4.5 million of
subordinated debentures, the Company sold warrants, at $.023 per warrant to
purchase 695,652 shares of Common Stock, which are reserved for future
issuance, at an exercise price of $4.485 per share. The warrants are 100%
exercisable and expire on December 31, 2002. For accounting purposes, the
deemed value of the warrants was treated as additional financing costs and
amortized to interest expense over the outstanding period of the subordinated
debentures. As a result of the repayment of the subordinated debentures from
the proceeds of the initial public offering, these costs were written off as
part of the extraordinary charge to earnings in the second quarter of fiscal
1996.
 
  In July 1995, the Board of Directors amended and restated the Incentive
Stock Option Plan of 1993. Under the Amended and Restated 1993 Stock Incentive
Plan, 1,521,739 shares of Common Stock can be issued through the exercise of
Incentive Stock Options, increasing 5% annually each July 1 during the term of
the Plan. At July 1, 1996, a maximum of 1,793,069 shares were reserved for
issuance. These options allow full-time employees, including officers, to
purchase shares of Common Stock at prices equal to fair market value at the
date of grant. For individuals who own more than 10% of the Common Stock of
the Company, the option price of the shares may not be less than 110% of the
fair market value on the date of grant. The vesting period and expiration of
each grant will be determined by the Compensation Committee of the Board of
Directors. This limitation does not apply to nonqualified stock options or
restricted stock awards that may be granted under the amended 1993 Plan.
 
  Under the Amended and Restated 1993 Stock Incentive Plan adopted in July,
1995, "non-qualified" stock options can be issued to full-time employees,
including officers and non-employee consultants. Options must be granted at an
exercise price of at least 85% of the fair market value on the date of grant.
The vesting period and expiration of each grant will be determined by the
Compensation Committee of the Board of Directors.

  In July 1995, the Board of Directors and stockholders approved the 1995 Non-
Employee Director Stock Option Plan. Under the Non-Employee Director Option

  In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"). As allowed by SFAS 123, the Company will not
recognize compensation cost for stock-based employee compensation
arrangements, but rather, commencing in fiscal 1997, will disclose in the
notes to the consolidated financial statements the impact on net income and
earnings per share as if the fair value based compensation cost had been
recognized.

7. EMPLOYEE BENEFIT PLANS
 
  The Company maintains a qualified Employee Stock Ownership Plan ("ESOP" or
the "Plan") which has been established in accordance with the requirements and
provisions of the Employee Retirement Income Security Act of 1974 ("ERISA")
and has been approved by the Internal Revenue Service ("IRS").
 
  Annually, the Board of Directors determines the contribution, if any, to the
Employee Stock Ownership Trust ("ESOT") which trust has been established under
the Plan for the purpose of administering and investing the funds contributed
by the Company. Annual contributions to the ESOP are not to exceed 15% of the
aggregate gross payroll of all participants. Payment of benefits may be
satisfied by the Company's stock, cash or a combination thereof. For each of
the years ended June 30, 1994 and 1995, the Company contributed $450 to the
ESOP. For the year ended June 30, 1996, the Company did not contribute to the
ESOP. Under the terms of the plan, the Company is required under certain
conditions to fund the repurchase of shares by the ESOP. In addition, the
Company is required to repurchase shares of former employees to the extent
funds are not available in the ESOP.
 
  The Company has a trusteed employee 401(k) savings plan for eligible U.S.
employees. The Company, effective October 1, 1996, matches 25% of employee
contributions up to a maximum employer contribution of 1.25% of the employee's
total compensation.
 
  For the fiscal year ended June 30, 1996, in lieu of a contribution to the
ESOP, the Company distributed $450 to all eligible New York employees through
direct cash payments.
 
  The Company's subsidiary in Switzerland maintains a defined contribution
plan which requires employee contributions based upon a percentage of the
employee's earnings currently ranging from 2.0% to 6.5%. The employer makes a
matching contribution based also upon a percentage of the employee's earnings
currently ranging from 3.5% to 11.0%. Company contributions ($430 in 1994,
$549 in 1995 and $737 in 1996) were charged to expense.
 
  In July 1995, the Company adopted the 1995 Employee Stock Purchase Plan and
reserved for issuance an aggregate of 434,783 shares of Common Stock. The Plan
allows eligible employees to purchase Common Stock, through payroll
deductions, at prices equal to 85% of fair market value on the first or last
business day of the offering period, whichever is lower. The option to
purchase Stock will terminate on July 7, 2005. As of June 30, 1996 and
December 31, 1996, 42,624 and 72,081 shares, respectively, have been issued
under the Employee Stock Purchase Plan and, as of June 30, 1996 and December
31, 1996, 392,159 and 362,702 shares were available for future grant,
respectively.

 Technology Dispute Settlement
 
  In the normal course of business, the Company and its subsidiaries are
parties to various legal claims, actions and complaints. Included among these
claims in fiscal 1994 was an intellectual property claim in the form of a
lawsuit which alleged patent infringement with respect to some of the
Company's oscilloscope products. In February, 1994, the Company concluded
negotiations to resolve this dispute and avoid extensive litigation. The
result was a settlement and a license agreement requiring an initial payment
by the Company of $1,549 on July 5, 1994, in addition to $524 of related legal
costs; legal costs amounted to $278 in 1993. Minimum annual future royalty
payments are $350 for ten years with potential for higher additional amounts
annually. These additional amounts are contingent on future product sales as
described in the settlement agreement and cannot exceed an aggregate of
$3,500. Royalty expense, which approximated $781 in 1995 and $963 in 1996, is
included in cost of sales.
 
 Restructuring Costs
 
  During 1994, the Company restructured its sales and marketing organization
and also closed its research facility in the United Kingdom; total charges
incurred were $930. The restructuring was accomplished by a combination of
relocation of certain employees, early retirement and severance payments.

requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act; and, where
interim financial information required to be presented by Article 3 of
Regulation S-X is not set forth in the Prospectus, to deliver, or cause to be
delivered to each person to whom the Prospectus is sent or given, the latest
quarterly report that is specifically incorporated by reference in the
Prospectus to provide such interim financial information.
 
  (C) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
  (D) The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of Prospectus shall
  be deemed to be a new Registration Statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof.
