                                  THE COMPANY
 
  ORBIT/FR, Inc. ("ORBIT/FR" or the "Company") develops, markets and supports
sophisticated automated microwave test and measurement systems for the wireless
communications, satellite, automotive and aerospace/defense industries.
Products such as cellular phones, satellites, radio transmitters, global
positioning system ("GPS") receivers and guided missiles depend on the reliable
and efficient transmission and reception of microwave signals in order to
communicate. By utilizing the Company's systems to measure the critical
performance characteristics of microwave signals, wireless manufacturers and
service providers within these industries can improve quality and time-to-
market, lower the risk of failure and underperformance and reduce costs.
Microwave test and measurement systems are used during all stages of a
product's life cycle: product development, pre-production qualification,
production testing and product maintenance.
 
  The need for microwave test and measurement systems and products expanded
rapidly during the 1960's and 1970's in conjunction with the growth and
increased sophistication of the aerospace/defense industry in the United States
and Western Europe. In the last 20 years, the need for microwave test and
measurement has expanded beyond aerospace/defense applications to all aspects
of modern telecommunications, including personal wireless communications
devices, satellite-based communications systems and "smart" automobiles. This
expansion has occurred in conjunction with a growing desire among companies to
focus on their core competencies and, accordingly, outsource many non-core
functions such as the development and manufacture of microwave test and
measurement systems.
 
  Since its founding, the Company has expanded from distributing individual
microwave test and measurement components to providing a wide range of fully
integrated microwave test and measurement solutions. Components of an ORBIT/FR
automated microwave test and measurement system include proprietary software
and hardware products, which can be combined into standard or customized
configurations to meet a customer's specific needs. The Company believes that
its innovative proprietary systems, experienced staff, reputation for quality
and reliability, strong international presence and comprehensive customer
service give it a competitive advantage that will enable it to remain a leading
global supplier of microwave test and measurement systems to a growing number
of companies within the wireless communications, satellite, automotive and
aerospace/defense industries.
   
  The Company markets and sells its systems to customers in the United States
and throughout the world. Within the Company's targeted industries, the
Company's customers since January 1, 1994 have included manufacturers of
wireless systems and products, such as Motorola, Nokia and Ericsson;
manufacturers of systems and products that incorporate microwave technology,
such as Lockheed Martin, Hughes Aircraft, BMW and Boeing; and
telecommunications service providers that rely on microwave technology, such as
AT&T, NTT and Korea Mobile Telecom. The Company's customers also include the
United States government and several foreign governments. In 1996, none of the
Company's customers accounted for more than 5% of the Company's total revenues.
At March 31, 1997, the Company's backlog was approximately $8.5 million,
compared to approximately $3.6 million at March 31, 1996.     
 
  The Company's objective is to strengthen its leadership position in automated
microwave test and measurement systems while developing products and systems
for a broader range of microwave applications. The principal elements of the
Company's strategy to reach its objective are: (i) offering comprehensive
solutions to customers, (ii) maintaining its technological leadership, (iii)
focusing on standard systems and proprietary off-the-shelf products, (iv)
pursuing growth in international markets and (v) leveraging its technological
expertise to expand into complementary markets.

                                 RISK FACTORS
 
  This Prospectus contains forward-looking statements that involve risks and
uncertainties. Actual results could differ materially from those discussed in
the forward-looking statements as a result of certain factors, including those
set forth below and elsewhere in this Prospectus. The following risk factors
should be considered carefully in addition to the other information in this
Prospectus before purchasing the shares of Common Stock offered hereby.
 
  RAPID TECHNOLOGICAL CHANGE. The microwave test and measurement industry is
characterized by rapid technological change. The Company's future success will
depend upon its ability continually to enhance its current products and to
develop and introduce new products that keep pace with the increasingly
sophisticated needs of its customers and the technological advancements of its
competitors. There can be no assurance that the Company will be successful in
developing and marketing product enhancements or new products that will
adequately meet the requirements of the marketplace. See "Business -- Systems
and Products" and "Business-- Research and Development."
 
  DEPENDENCE ON PROPRIETARY TECHNOLOGY. The Company's success is heavily
dependent upon its proprietary technology. The Company does not currently have
any material patents and relies principally on trade secret and copyright laws
to protect its technology. However, there can be no assurance that these steps
will prevent misappropriation of its technology. Moreover, third parties could
independently develop technologies that compete with the Company's
technologies. Although the Company believes that its products and proprietary
rights do not infringe patents and proprietary rights of third parties, there
can be no assurance that infringement claims, regardless of merit, will not be
asserted against the Company. In addition, effective copyright and trade
secret protection of the Company's proprietary technology may be unavailable
or limited in certain foreign countries. See "Business -- Proprietary Rights."
 
  RISKS ASSOCIATED WITH ACQUISITIONS. In the normal course of business, the
Company evaluates potential acquisitions that would complement or expand its
business. Subject to the completion of this offering, the Company will acquire
AEMI. There can be no assurance that the Company will be able to successfully
integrate the business and operations of AEMI or any other business acquired
in the future. There can be no assurance that the Company will not incur
disruptions and unexpected expenses in integrating such acquisitions. In
attempting to make acquisitions, the Company often competes with other
potential acquirors, many of which have greater financial and operational
resources. Furthermore, the process of evaluating, negotiating, financing and
integrating acquisitions may divert management time and resources. There can
be no assurance that any acquisition, when consummated, will not materially
adversely affect the Company's business, operating results or financial
condition. See "Business -- The ORBIT/FR Strategy" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
   
  DEPENDENCE ON ALCHUT; OPERATIONS IN ISRAEL. The Company maintains and will
continue to maintain a number of relationships with Alchut, the sole
stockholder of the Company prior to this offering. All of the Company's
electro-mechanical production requirements, primarily in connection with the
production of positioners, are currently subcontracted to Alchut. The amounts
paid by the Company to Alchut for its subcontracted production during 1994,
1995 and 1996 were $1.5 million, $1.4 million and $1.5 million, which
represented 28%, 26% and 23% of the Company's cost of revenues, respectively.
In addition, Alchut provides general and administrative services for the
Company's operations in Israel. Effective January 1, 1997, the Company and
Alchut entered into an agreement under which Alchut will continue to provide
these services for at least one year. See "Certain Transactions." Alchut
maintains its production operations, and the Company maintains part of its
engineering operations, in Israel. As a result, the Company may be directly
influenced by the political, economic and military conditions affecting
Israel. Such conditions may create production delays or stoppages which could
adversely affect the Company's ability to conduct operations.     
 
  RISKS OF FIXED-PRICE CONTRACTS. Virtually all of the Company's contracts for
its systems and products are on a fixed-price basis. The profitability of such
contracts is subject to inherent uncertainties as to the cost of
 
                                       6
<PAGE>
 
completion. In addition to possible errors or omissions in making initial
estimates, cost overruns may be incurred as a result of unforeseen obstacles,
including both physical conditions and unexpected problems in engineering,
design or testing. Since the Company's business may at certain times be
concentrated in a limited number of large contracts, a significant cost
overrun on any one contract could have a material adverse effect on the
Company's business, operating results and financial condition.
 
  RISKS ASSOCIATED WITH ENTERING NEW MARKETS. The Company has identified and
is evaluating whether to enter into certain complementary markets and may use
a portion of the proceeds of this offering to expand into these markets. The
Company's success in these markets will depend on, among other factors, the
Company's ability to identify markets and develop technologies for such
markets on a timely basis, hire and retain skilled management, financial,
marketing and engineering personnel, successfully manage growth and obtain
capital sufficient to finance such expansion. There can be no assurance that
the Company will successfully enter these markets. See "Use of Proceeds" and
"Business -- The ORBIT/FR Strategy."
   
  MANAGEMENT OF GROWTH. The Company is currently experiencing a period of
rapid growth in the number of employees and in the scope of its business. In
addition, the Company believes that continued growth will be required to
maintain the Company's competitive position. The Company's rapid growth,
coupled with the rapid evolution of the Company's markets, has placed, and is
likely to continue to place, strains on its management, administrative,
operating and financial resources, as well as increased demands on its
internal systems, procedures and controls. For example, as the Company further
expands, existing management will be required to supervise more wide-spread
and diversified operations and additional management personnel will have to be
hired and trained. The Company's ability to manage recent and future growth
will require the Company to devote additional management time to its financial
and management controls, reporting systems and procedures and to expand,
train, motivate and manage its sales and technical personnel. There can be no
assurance that the Company will be able to manage its growth successfully.
Failure to do so could have a material adverse effect on the Company's
business, operating results and financial condition.     
   
  RISKS ASSOCIATED WITH INTERNATIONAL SALES. In 1996, international sales
comprised approximately 52% of the Company's total sales, and the Company
expects its international business to continue to account for a material part
of its revenues. International sales are subject to numerous risks, including
political and economic instability in foreign markets, restrictive trade
policies of foreign governments, inconsistent product regulation by foreign
agencies or governments, imposition of product tariffs and burdens and costs
of complying with a wide variety of international and U.S. export laws and
regulatory requirements. There can be no assurance that the Company will be
able to continue to compete successfully in international markets or that its
international sales will be profitable. Approximately 92% of the Company's
revenues in 1996 were denominated in U.S. dollars, and the Company intends to
continue to enter into U.S. dollar-denominated contracts. Accordingly, the
Company believes that it does not have significant exposure to fluctuations in
currency. However, fluctuations in currency could adversely affect the
Company's customers. See "Business -- The ORBIT/FR Strategy."     
   
  POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS. The Company's operating results
have varied from quarter to quarter in the past and may vary significantly in
the future depending on factors such as the size and timing of significant
contracts, the mix of third party products and the Company's proprietary
products included in a particular contract, customers' budgetary constraints,
increased competition, the timing of new product announcements and changes in
pricing policies by the Company or its competitors, market acceptance of new
and enhanced versions of the Company's products, changes in operating expenses
and changes in general economic factors. During the five quarters ended March
31, 1997, the Company's revenues were $1.5 million, $1.8 million, $2.8
million, $4.2 million and $4.9 million, respectively, and the Company's net
income was $27,000, $50,000, $193,000, $561,000 and $586,000, respectively.
The Company's expense levels are based, in part, on its expectations as to
future revenue levels. If the Company's revenue levels were to be below
expectations, the Company's operating results would likely be materially
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Quarterly Results of Operations."     
 
  DEPENDENCE ON QUALIFIED TECHNICAL PERSONNEL. The Company's operating results
depend in large part upon the efforts of its microwave, software and systems
engineers. The success of the Company's business therefore
 
                                       7
<PAGE>
 
depends on its ability to attract and retain engineers and other technical
personnel. There are a limited number of microwave engineers, and such
individuals are sought both by microwave test and measurement companies such
as the Company and by manufacturers of wireless products and
telecommunications service providers. Competition for such personnel is
intense. The Company has at times experienced difficulty in recruiting and
retaining technical personnel, and there can be no assurance that the Company
will not experience difficulties in the future in attracting and in retaining
technical personnel. See "Business -- Employees."
   
  DEPENDENCE ON KEY PERSONNEL. The success of the Company depends to a
significant degree upon the contribution of its executive officers and other
key personnel, including Mr. Aryeh Trabelsi, the Company's President and Chief
Executive Officer. Other than Mr. Trabelsi, none of the Company's executive
officers has an employment agreement with the Company, except that Mr. Moshe
Pinkasy has an agreement that is terminable upon 90 days notice. There can be
no assurance that the Company will be able to retain its managerial and other
key personnel or to attract additional managerial and other key personnel if
required. See "Business -- Employees" and "Management."     
 
  PRODUCT LIABILITY; RISK OF PRODUCT DEFECTS. The sale of products and systems
by the Company may entail the risk of product liability and related claims. A
product liability claim brought against the Company could have a material
adverse effect upon the Company's business, operating results and financial
condition. Complex software and system products, such as those offered by the
Company, may contain defects or failures when introduced or when new versions
are released. There can be no assurance that, despite testing by the Company,
errors will not be found in new products after commencement of commercial
shipments, resulting in loss of market share or failure to achieve market
acceptance. The Company maintains product liability insurance in the amount of
$3.0 million and errors and omissions insurance in the amount of $1.0 million,
although there can be no assurance that such coverage will be applicable to a
particular claim or that the amounts of such insurance will be adequate if the
Company experiences a significant claim. Although the Company has not
experienced any significant claims to date related to its systems or products,
the occurrence of such a claim could have a material adverse effect upon the
Company's business, operating results and financial condition.
 
  COMPETITION. The market for automated microwave test and measurement
products, systems and services is highly competitive and is characterized by
continuing advances in products and technologies. In general, competition in
this market comes from major microwave test and measurement vendors, some of
which have a longer operating history, significantly greater financial,
technical and marketing resources, greater name recognition and a larger
installed customer base than the Company. These companies also have
established relationships with current and potential customers of the Company.
The Company also competes, on a limited basis, with the internal development
groups of its existing and potential customers, who may design and develop
parts of their own microwave test and measurement systems. The Company's
business, operating results and financial condition could be materially
adversely affected by such competition. See "Business -- Competition."
 
  FLUCTUATIONS IN CAPITAL SPENDING. The Company is dependent upon the wireless
communications, satellite, automotive and aerospace/defense industries.
Because these industries are characterized by technological change, pricing
and gross margin pressure and, particularly in the aerospace/defense industry,
government budget constraints, they have from time to time experienced sudden
economic downturns. During these periods, capital spending is frequently
curtailed and the number of design projects often decreases. Since the
Company's sales are dependent upon capital spending trends and new design
projects, negative factors affecting these industries could have a material
adverse effect on the Company's business, operating results and financial
condition.
   
  CONTROL BY PRINCIPAL STOCKHOLDER. Upon completion of this offering, Alchut
will beneficially own 65.6% of the outstanding Common Stock of the Company
(60.7% if the Underwriters' over-allotment option is exercised in full). Mr.
Joseph Aviv, Chairman of the Board of the Company, and Mr. Zeev Stein, a
director of the Company, and their families currently own approximately 44.0%
and 42.0% of the outstanding shares of Alchut, respectively. As a result,
these individuals and Alchut will be in a position to control the outcome of
all matters requiring stockholder approval, including the election or removal
of directors, approval of significant corporate transactions and the ability
generally to direct the Company's affairs. Such concentration of ownership may
have the effect of delaying or preventing a change in control of the Company,
including transactions in which the     
 
                                       8
<PAGE>
 
holders of the Company's Common Stock might otherwise receive a premium over
current market prices for their shares. See "Principal Stockholders."
 
  DISCRETIONARY USE OF PROCEEDS. The Company intends to use the proceeds of
this offering to pay up to $800,000 in connection with the AEMI acquisition
and for working capital and other general corporate purposes, including
possible acquisitions. Accordingly, the Company's management will have broad
discretion with respect to the use of the net proceeds of this offering. See
"Use of Proceeds."
 
  NO PRIOR TRADING MARKET FOR COMMON STOCK; POTENTIAL VOLATILITY OF STOCK
PRICE. Prior to this offering, there has been no public market for the Common
Stock, and there can be no assurance that an active trading market will
develop or be sustained after this offering. The initial public offering price
was determined through negotiations between the Company and the
Representatives of the Underwriters based on several factors and may not be
indicative of the market price of the Common Stock after this offering. See
"Underwriting." The market price of the shares of Common Stock may be
significantly affected by factors such as actual or anticipated fluctuations
in the Company's operating results, announcements of technological
innovations, new products or new contracts by the Company or its competitors,
developments with respect to copyrights or proprietary rights, conditions and
trends in the microwave test and measurement industry, adoption of new
accounting standards affecting the software industry, general market
conditions and other factors. In addition, the stock market has, from time to
time experienced significant price and volume fluctuations that have
particularly affected the market prices for the common stock of technology
companies and that have often been unrelated to the operating performance of
particular companies.
   
  DILUTION. The initial public offering price is substantially higher than the
pro forma net tangible book value per share of Common Stock. Investors
purchasing shares of Common Stock in this offering at the Offering Price will
therefore incur immediate and substantial dilution of $5.66 in pro forma net
tangible book value per share. See "Dilution."     
 
  NO DIVIDENDS. The Company has never paid cash dividends on its Common Stock
and does not anticipate that any cash dividends will be declared or paid in
the foreseeable future. See "Dividend Policy."
   
  SHARES ELIGIBLE FOR FUTURE SALE. Sales of substantial amounts of Common
Stock in the public market after this offering may have an adverse effect on
the market price of the Common Stock. Upon completion of this offering, the
Company will have outstanding 6,094,118 shares of Common Stock assuming the
maximum of 94,118 shares are issued in connection with the acquisition of
AEMI. Of these shares, 2,000,000 shares sold in this offering generally will
be freely transferable without restriction. The remaining 4,094,118 shares,
4,000,000 of which are owned by Alchut and a maximum of 94,118 of which will
be issued in connection with the acquisition of AEMI, may not be sold unless
registered under the Securities Act of 1933, as amended (the "Securities
Act"), or an exemption from registration is available, including the exemption
provided by Rule 144 under the Securities Act. Alchut and the Company's
directors and executive officers have agreed that they will not, other than by
Alchut with respect to the over-allotment option, directly or indirectly,
offer, sell, contract to sell, pledge, grant any option for the sale of or
otherwise dispose of any shares of Common Stock or any securities convertible
into, or exercisable or exchangeable for, any shares of Common Stock for a
period of 180 days after the date of this Prospectus without the prior written
consent of the Representatives of the Underwriters, other than in certain
private transactions in which each transferee acquiring an interest in such
Common Stock during such 180-day period agrees in writing to be bound by such
agreement. After such 180-day period, the 4,000,000 shares of Common Stock
held by Alchut will be eligible for sale in the public market in reliance upon
Rule 144 subject to the restrictions contained therein. The current
stockholders of AEMI have agreed with the Company that they will not offer,
sell or otherwise dispose of the maximum of 94,118 shares of Common Stock
issued in connection with the acquisition of AEMI for a period of two years
after the closing date of such acquisition. After such two-year period, the
maximum of 94,118 shares held by such stockholders will be eligible for sale
under Rule 144 subject to the restrictions contained therein. After 180 days
from the date of this Prospectus, the Company intends to register under the
Securities Act 800,000 shares of Common Stock reserved for awards under the
Company's 1997 Equity Incentive Plan. See "Underwriting" and "Shares Eligible
for Future Sale."

  ISSUANCE OF PREFERRED STOCK AND COMMON STOCK; ANTI-TAKEOVER PROVISIONS.
Pursuant to its Amended and Restated Certificate of Incorporation, the Company
has an authorized class of 2,000,000 shares of Preferred Stock which may be
issued by the Board of Directors with such terms and such rights, preferences
and designations as the Board may determine and without any vote of the
stockholders, unless otherwise required by law. Issuance of such Preferred
Stock, depending upon the rights, preferences and designations thereof, may
have the effect of delaying, deterring or preventing a change in control of
the Company. Issuance of additional shares Common Stock could result in
dilution of the voting power of the Common Stock purchased in this offering.
In addition, certain "anti-takeover" provisions of the Delaware General
Corporation Law (the "DGCL") among other things, may restrict the ability of
the stockholders to approve a merger or business combination or obtain control
of the Company. See "Description of Securities."
 
                                      10
<PAGE>
 
                                  THE COMPANY
 
  ORBIT/FR, Inc. ("ORBIT/FR" or the "Company") was incorporated in Delaware in
December 1996. The Company is the holding company for Orbit Advanced
Technologies, Inc., a Delaware corporation ("Technologies") and its wholly
owned subsidiary, Flam & Russell, Inc., a Delaware corporation ("Flam &
Russell"), and for Orbit F.R. Engineering, Ltd., an Israeli corporation
("Engineering"). Prior to the completion of this offering, Orbit-Alchut
Technologies, Ltd., a publicly traded company in Israel which was founded in
1950 ("Alchut"), owned all of the 4,000,000 issued and outstanding shares of
the Company. In addition to its ownership interests in the Company, Alchut has
ownership interests in companies operating in the avionics, tracking and
telemetry markets.
 
  Technologies was incorporated in 1985 as a wholly-owned subsidiary of Alchut
to provide sales and customer support for Alchut's products in the United
States, including positioning subsystems. In 1991, Technologies began to focus
on the development and design of its own proprietary microwave test and
measurement products and systems. In 1994, Technologies recognized the
potential for providing customers with fully integrated microwave test and
measurement solutions and began incorporating Technologies' software
technology with hardware from third-party manufacturers, including Alchut.
Technologies continues to subcontract certain production services to Alchut
through Engineering but retains the right to select any other production
subcontractor after January 1, 1998. See "Certain Transactions."
 
  Engineering was incorporated in Israel in December 1996 as a wholly-owned
subsidiary of Alchut at which time Alchut transferred all of the assets
relating to its microwave test and measurement business to Engineering.
Engineering is principally responsible for overseeing the development, design
and production of ORBIT/FR's electro-mechanical products.
   
  Effective December 31, 1996, Alchut transferred or caused to be transferred
to the Company all of the outstanding shares of Technologies and Engineering
in exchange for shares of the Company, thereby making Technologies and
Engineering wholly-owned subsidiaries of the Company.     
   
  On June 28, 1996, Technologies purchased all of the issued and outstanding
shares of Flam & Russell for approximately $1,043,000. The acquisition of Flam
& Russell augmented the Company's product mix, staff of microwave and software
engineers and customer base. Flam & Russell has been active in the microwave
test and measurement field since 1981. At the time it was acquired by the
Company, Flam & Russell was one of the Company's direct competitors and
offered products that were both complementary to and competitive with the
Company's products.     
   
  On March 31, 1997, the Company entered into an agreement with Advanced
Electromagnetics, Inc., a California corporation ("AEMI"), and its
stockholders, pursuant to which all of the issued and outstanding shares of
AEMI will be sold to the Company, contemporaneously with the completion of
this offering, for up to a maximum of $1.6 million, subject to a possible
downward adjustment based on AEMI's financial performance for the three years
ended March 31, 1997. One-half of the purchase price will be paid in cash and
the other half will be paid by issuance of shares of the Company's Common
Stock valued at the Offering Price. Founded in 1980, AEMI manufactures
anechoic foam, a microwave absorbing material that is used to line indoor test
chambers and that is an integral component of microwave test and measurement
systems. For the year ended December 31, 1996, AEMI had revenues of $3.2
million and a pre-tax profit of $544,000. As of and for the quarter ended
March 31, 1997, AEMI had revenues of $933,000, a pre-tax profit of $205,000,
assets of $1.2 million and net equity of $510,000. The Company believes that
the acquisition of AEMI will enhance its ability to provide comprehensive test
and measurement solutions to its customers.     
 
  The Company's principal offices are located at 506 Prudential Road, Horsham,
Pennsylvania 19044. Its telephone number is (215) 674-5100, its e-mail address
is [email protected] and its World Wide Web home page is located at

                                USE OF PROCEEDS
 
  The net proceeds to the Company from the sale of the 2,000,000 shares of
Common Stock offered by the Company hereby at the Offering Price are estimated
to be approximately $15,125,000 after deducting underwriting discounts and
commissions and estimated offering expenses. The Company intends to use the
net proceeds as follows: (i) up to $800,000 to pay the cash portion of the
purchase price (assuming the maximum purchase price) for the AEMI acquisition
(see "The Company"); and (ii) the balance for working capital and other
general corporate purposes, including the investment in or acquisition of
complementary businesses, products, product development rights or
technologies. Other than the acquisition of AEMI described in "The Company,"
the Company has no current understanding, commitment or arrangement with
respect to any potential investment or acquisition. Pending such uses, the net
proceeds will be invested in short-term, interest-bearing investment grade
securities or commercial paper. The Company will not receive any proceeds from
the sale of Common Stock pursuant to any exercise of the Underwriters' over-
allotment option.
 
                                CAPITALIZATION
   
  The following table sets forth the capitalization of the Company as of March
31, 1997 and as adjusted to reflect the sale of the 2,000,000 shares of Common
Stock offered by the Company at the Offering Price and the application of the
estimated net proceeds therefrom. See "Use of Proceeds."

                                DIVIDEND POLICY
 
  The Company has never paid any cash dividends on its Common Stock and does
not intend to pay cash dividends on its Common Stock in the foreseeable
future. The Company currently intends to reinvest its earnings, if any, in the
development and expansion of the Company's business. Any future declaration of
cash dividends will be at the discretion of the Company's Board of Directors
and will depend upon the earnings, capital requirements and financial position
of the Company, general economic conditions and other pertinent factors.
 
                                   DILUTION
   
  At March 31, 1997, the pro forma net tangible book value of the Company was
$2,117,775 or $0.52 per share of Common Stock. Pro forma net tangible book
value per share represents the amount of total tangible assets reduced by the
amount of total liabilities and divided by the number of outstanding shares of
Common Stock, after giving effect to the acquisition of AEMI. After giving
effect to the receipt by the Company of the net proceeds from the sale of the
Common Stock offered by the Company hereby at the Offering Price and after
deducting underwriting discounts and commissions and estimated offering
expenses, the adjusted pro forma net tangible book value of the Company at
March 31, 1997 would have been $17,242,775 or $2.84 per share of Common Stock.
This represents an immediate increase in pro forma net tangible book value of
$2.32 per share to the existing stockholders and an immediate dilution of pro
forma net tangible book value of $5.66 per share to purchasers of the Common
Stock offered hereby. The following table illustrates this per share dilution:

(1) The sale of shares of Common Stock by Alchut, if the Underwriters' over-
    allotment option is exercised in full, would reduce the number of shares
    held by existing stockholders to 3,794,118 shares, or approximately 62.3%
    of the total number of shares outstanding after this offering, and would
    increase the number of shares held by new investors to 2,300,000 shares,
    or approximately 37.7% of the total number of shares outstanding after
    this offering.
 
  The foregoing table (under existing stockholders) includes a maximum of
94,118 shares of Common Stock that will be issued contemporaneously with the
completion of this offering in connection with the AEMI acquisition. The
foregoing table does not include the exercise of outstanding options.
Effective upon the completion of this offering, the Company has granted
options to purchase an aggregate of 492,300 shares of Common Stock at an
exercise price equal to the Offering Price. The Company has reserved an
additional 307,700 shares of Common Stock for future stock option grants. See
"Management -- 1997 Equity Incentive Plan."

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion of the Company's historical results of operations
and liquidity and capital resources should be read in conjunction with the
Selected Consolidated Financial Data, the Consolidated Financial Statements of
the Company and related Notes thereto and other financial information
appearing elsewhere in this Prospectus. As used in this section, the term
"Company" includes the Company and its predecessors.
 
BASIS OF PRESENTATION
 
  ORBIT/FR was incorporated in December 1996, is the holding company for
Technologies, Engineering and Flam & Russell, and is a wholly-owned subsidiary
of Alchut. Technologies was incorporated in 1985 and its historical results
are included for all periods presented. In June 1996, Technologies acquired
Flam & Russell in a transaction accounted for as a purchase. Flam & Russell's
results of operations have been consolidated since the date of acquisition. In
August 1994, Alchut established a separate business unit dedicated to
microwave test and measurement which was incorporated as a separate corporate
entity in December 1996 under the name Engineering. Accordingly, since 1994,
the consolidated results of the Company reflect Technologies and Engineering
on an as-if pooled basis for the period that Technologies and Engineering were
under common control. All intercompany accounts and transactions have been
eliminated.
 
OVERVIEW
 
  Prior to 1994, the Company generated its revenues principally from sales of
microwave test and measurement software and from commission revenues generated
by the sales of Alchut's products in the United States. In 1994, the Company
recognized the potential for providing customers with fully integrated
microwave test and measurement solutions and began incorporating the Company's
software technology with hardware from third-party manufacturers, including
Alchut. Because the Company's systems and products are used as part of its
customers' manufacturing processes, the Company's growth is largely dependent
on the expansion of its customers' product development and production efforts.
 
  The Company's systems and products are sold either under fixed-price or
cost-plus contracts and are accounted for on the percentage of completion
method. Approximately 93.7% of the Company's revenues for the year ended
December 31, 1996 were derived from fixed-price contracts or purchase orders
which require the Company to provide systems and products at pre-negotiated
prices. The Company derived approximately 5.0% of its revenues in the same
period from cost-plus contracts in which customers are charged based on the
costs incurred by the Company. Cost-plus contracts are generally entered into
in connection with research and development projects that are performed for
the United States and Israeli governments. The balance of the Company's
revenues for the year ended December 31, 1996 were commissions generated from
the sales of non-microwave test and measurement systems and products, which
the Company began to de-emphasize in 1996 and will discontinue in mid-1997.
   
  At March 31, 1997, the Company had a backlog of approximately $8.5 million,
compared to a backlog of approximately $3.6 million at March 31, 1996. The
Company's backlog includes only those orders for which it has received and
accepted a completed purchase order. The backlog at March 31, 1997 is expected
to be delivered in 1997. This backlog represents an average sales cycle of
approximately five months.     
 
  A significant portion of the Company's research and development expenses has
been incurred while developing the specific requirements for particular
customers' orders and, therefore, are included in the cost of revenues. The
related funding (which includes a profit component) is included in revenues at
such time. The Company believes that its ability to offer a custom solution to
customers is an important competitive advantage. During 1996, the Company
recognized $2.2 million in revenues from this activity, including $520,000 in
customer-funded research and development. Such customer-funded research has
enabled and will continue to
 
                                      20
<PAGE>
 
   
enable the Company to update and expand upon its existing product line. During
the years ended December 31, 1996, 1995 and 1994, 47.2%, 66.8% and 66.5%,
respectively, of the Company's total research and development expenses are
included in the cost of revenues.     
 
  Since 1992, the Company has increased its independent research and
development in connection with the development of turnkey microwave test and
measurement products and systems. The Company expects such expenses to
continue to increase as the Company enhances its microwave test and
measurement product line and develops new products for the EMC market and
other microwave-related markets.
 
  In 1994, in connection with its conversion from a distributor for Alchut
products to a full service provider of its own microwave test and measurement
systems and products, the Company began selling its systems and products
overseas. In 1996, while approximately 52.0% of the Company's revenues was
derived from overseas customers, approximately 92.0% of its revenues in 1996
was denominated in U.S. dollars. Accordingly, the Company believes that it
does not have significant exposure to fluctuations in currency.
 
  The Company believes that its future financial performance will depend
substantially on its success in acquiring companies that provide complementary
products and services, capitalizing on global infrastructure development,
providing standard solutions and expanding into complementary markets that
leverage the Company's technological expertise.
 
  The acquisition of Flam & Russell on June 28, 1996 gave the Company greater
price flexibility and also augmented the Company's product mix, staff of
microwave and software engineers and customer base. The acquisition was
accounted for as a purchase transaction with a purchase price of approximately
$1,043,000 and resulted in no recognition of goodwill. Flam & Russell's
backlog at the time of the acquisition was $2.4 million. In connection with
this acquisition, the Company recorded purchased software of $352,000 and
approximately $384,000 in deferred tax assets and credits, which can be used
to offset future taxes.
   
  The Company has an agreement to acquire AEMI upon the completion of this
offering for up to a maximum of $1.6 million, subject to adjustment based on
AEMI's financial performance for the three years ended March 31, 1997. One-
half of the purchase price will be paid in cash and the other half will be
paid by issuance of shares of the Company's Common Stock valued at the
Offering Price. The Company believes that this acquisition will further
broaden its product line and enable it to offer more comprehensive microwave
test and measurement solutions to its customers.

THREE MONTHS ENDED MARCH 31, 1997 COMPARED TO THE THREE MONTHS ENDED MARCH 31,
1996     
   
  Revenues. Revenues for the three months ended March 31, 1997 were $4.9
million compared to $1.5 million for the three months ended March 31, 1996, an
increase of approximately $3.4 million or 226.7%. Revenues from microwave test
and measurement accounted for virtually all of the increase. Approximately
$2.0 million of the increase was attributable to the aerospace/defense
industry, which resulted from an improvement in the Company's ability to
capture opportunities within that industry following the acquisition of Flam &
Russell and strong growth in the industry's domestic commercial sector.
Approximately $900,000 of the increase was attributable to the wireless
communications industry and the remaining $500,000 of the increase was
attributable to the satellite industry.     
   
  Cost of revenues. Cost of revenues for the three months ended March 31, 1997
were $3.1 million compared to $1.1 million for the three months ended March
31, 1996, an increase of approximately $2.0 million or 181.8%. Gross margins
rose from 29.0% for the three months ended March 31, 1996 to 36.0% for the
three months ended March 31, 1997, as a result of improved efficiencies in the
proposal, production and delivery stages of providing turnkey systems and the
implementation of the Company's strategy to sell standard systems and
proprietary off-the-shelf products, which generate higher margins. Cost of
revenues and gross margin for the three months ended March 31, 1997 were
negatively impacted by the completion of a $540,000 revenue contract with a
relatively low gross margin which the Company assumed when it acquired Flam &
Russell.     
   
  General and administrative expenses. General and administrative expenses for
the three months ended March 31, 1997 were $319,000 compared to $195,000 for
the three months ended March 31, 1996, an increase of approximately $124,000
or 63.6%. As a percentage of revenues, general and administrative expenses
decreased from 12.7% for the three months ended March 31, 1996 to 6.5% for the
three months ended March 31, 1997 due to an increase in revenues without a
corresponding increase in general and administrative expenses.     
   
  Sales and marketing expenses. Sales and marketing expenses for the three
months ended March 31, 1997 were $273,000 compared to $112,000 for the three
months ended March 31, 1996, an increase of approximately $161,000 or 143.8%.
As a percentage of revenues, sales and marketing expenses were 5.6% for the
three months ended March 31, 1997, a decrease from 7.3% for the three months
ended March 31, 1996. Approximately $65,000 of this increase represents higher
commissions due to increased sales, approximately $64,000 reflects the
addition of the Flam & Russell sales force and approximately $30,000 is
attributable to market research efforts.     
   
  Research and development expenses. Research and development expenses for the
three months ended March 31, 1997 were $220,000 compared to $97,000 for the
three months ended March 31, 1996, an increase of $123,000 or 126.8%. This
increase reflects the additional development relating to the modification of
the Flam & Russell software to support the Company's hardware products and the
development required to support the needs of the Company's test and
measurement systems for the "smart" automobile and wireless communications
industries.     
   
  Income taxes. Income tax expense for the three months ended March 31, 1997
was $344,000 compared to $20,000 for the three months ended March 31, 1996, an
increase of $324,000. The Company's effective tax rate decreased from 42.6%
for the three months ended March 31, 1996 to 37.0% for the three months ended
March 31, 1997 as a result of the implementation of new domestic tax
strategies designed to reduce its effective tax rate.     
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
  Revenues. Revenues for 1996 were $10.4 million compared to $8.3 million in
1995, an increase of approximately $2.1 million or 25.3%. Revenues from
microwave test and measurement for 1996 were $10.3 million compared to $8.0
million in 1995, an increase of approximately $2.3 million or 28.9%.
Approximately $1.2 million of the increase was attributable to Flam &
Russell's backlog at the time of the acquisition. The Company's initiation of
sales of microwave test and measurement systems to manufacturers of "smart"
automobiles contributed $600,000 to the growth in revenues, and the balance of
the increase was attributable to
 
                                      22
<PAGE>
 
sales in the wireless communications and satellite industries. Commission
revenues from non-microwave test and measurement decreased $205,000 from the
prior year as the Company began to phase out the sale of such systems.
   
  Cost of revenues. Cost of revenues for 1996 were $6.5 million compared to
$5.4 million in 1995, an increase of approximately $1.1 million or 20.4%. As a
percentage of microwave test and measurement revenues, cost of revenues
decreased to 62.8% in 1996 from 68.4% in 1995. This increase in gross margin
reflected improved efficiencies in the proposal, production and delivery
stages of providing turnkey systems and illustrated the Company's shift to the
sale of standard systems and proprietary off-the-shelf products. The increased
gross margin was partially offset by an increase of approximately $1.0 million
in the sale of third-party products used as components in the Company's test
and measurement systems. These third-party products generally have a lower
gross margin than the Company's systems and products.     
   
  General and administrative expenses. General and administrative expenses for
1996 were $1.3 million compared to $864,000 in 1995, an increase of
approximately $436,000 or 50.5%. As a percentage of revenues, general and
administrative expenses were 12.6% in 1996 and 10.4% in 1995. Approximately
$196,000 of this increase was the result of the expansion and centralization
of the administrative and finance functions related to the growth of the
Company. Approximately $162,000 of this increase was due to the acquisition of
Flam & Russell in June 1996, which included certain transition costs and
temporary redundancies, and approximately $82,000 of the increase was
attributable to legal and accounting fees.     
   
  Sales and marketing expenses. Sales and marketing expenses for 1996 were
$791,000 compared to $994,000 in 1995, a decrease of approximately $203,000 or
20.4%. As a percentage of revenues, sales and marketing expenses were 7.6% in
1996 and 12.0% in 1995. Approximately $290,000 of this decrease was the result
of the Company's decision during 1996 to consolidate its sales and marketing
operations at the Company's headquarters in Horsham, Pennsylvania, in addition
to lower commissions negotiated with some of the Company's independent sales
representatives in the Far East. This decrease was partially offset by an
increase in the Company's direct sales force and marketing personnel resulting
from the acquisition of Flam & Russell and a decision to expand the Company's
direct sales force in the United States which together increased sales and
marketing expenses by $115,000.     
   
  Research and development expenses. Research and development expenses for
1996 were $581,000 compared to $239,000 in 1995, an increase of $342,000 or
143.1%. The increase reflected the additional research and development
relating to the modification of the Flam & Russell software to support the
Company's hardware products, the software development required to support the
needs of the Company's test and measurement systems for the "smart" automobile
and wireless communications industries and additional funds spent on porting
the Company's software products to Windows 95.     
 
  Other income. Other income decreased $35,000 in 1996 from 1995 principally
as a result of higher interest expense in 1996.
 
  Income taxes. Income tax expense for 1996 was $439,000 compared to $301,000
in 1995, an increase of $138,000. The Company's effective tax rate decreased
from 37.9% in 1995 to 34.6% in 1996, as a result of a greater percentage of
the Company's income being generated from its subsidiary in Israel where the
tax rate is lower.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
   
  Revenues. Revenues for 1995 were $8.3 million compared to $7.2 million in
1994, an increase of approximately $1.1 million or 15.3%. Revenues from
microwave test and measurement for 1995 were $8.0 million compared to $7.1
million in 1994, an increase of approximately $900,000 or 12.7%. The Company
experienced increased sales to customers within the wireless communications
industry and to customers in the Far East. These increases were partially
offset by the completion of a $2.5 million project in the satellite industry
    
                                      23
<PAGE>
 
   
in 1994 and a decrease in sales in the aerospace/defense industry in the
United States. Commission revenues from non-microwave test and measurement
increased from $43,000 in 1994 to $342,000 in 1995, an increase of $299,000.
In 1994, commission revenues were negatively impacted by a loss in connection
with a large customer contract.     
   
  Cost of revenues. Cost of revenues for 1995 were $5.4 million compared to
$5.3 million in 1994, an increase of approximately $100,000 or 2.0%. As a
percentage of microwave test and measurement revenues, cost of revenues
decreased to 68.4% in 1995 from 73.9% in 1994. This improvement in the
Company's gross margin primarily reflected an improvement in the Company's
ability to forecast and manage the costs associated with fixed-price contracts
for turnkey systems, an on-going effort to develop and build proprietary off-
the-shelf products and increased sales of approximately $1.3 million to
customers in the Far East where sales typically have higher gross margins to
offset higher selling commissions.     
   
  General and administrative expenses. General and administrative expenses for
1995 were $864,000 compared to $989,000 in 1994, a decrease of approximately
$125,000 or 12.6%. As a percentage of revenues, general and administrative
expenses were 10.4% in 1995 and 13.8% in 1994. During the transition to
turnkey systems sales in 1994, management from Alchut provided considerable
direct assistance to the Company. By 1995, the Company was able to perform
most of the design and marketing functions of these systems on its own,
thereby decreasing general and administrative expenses by approximately
$100,000. The decrease in general and administrative expenses during this
period was also attributable to greater efficiencies in managerial and
administrative functions.     
 
  Sales and marketing expenses. Sales and marketing expenses for 1995 were
$994,000 compared to $786,000 in 1994, an increase of approximately $208,000
or 26.5%. As a percentage of revenues, sales and marketing expenses increased
to 12.0% in 1995 from 11.0% in 1994. This increase was largely the result of
higher sales in the Far East where sales representatives receive higher
commissions. The Company also had increased its expenditures for training,
seminars and other promotions overseas.
 
  Research and development expenses. Research and development expenses
remained unchanged at $239,000 in 1995 compared to $237,000 in 1994. Research
and development expenditures were attributable to developments in the wireless
communications industry in 1995, compared to developments in the satellite
industry and the development of the Company's turnkey systems in 1994.
 
  Other income. Other income decreased $33,000 in 1995 from 1994 as a result
of miscellaneous income received in 1994.
 
  Income taxes. Income tax expense for 1995 was $301,000 compared to a benefit
of $119,000 in 1994. The benefit in 1994 reflects the low effective tax rate
in Israel resulting from adjustments to the statutory rate allowable under
local law.
   
QUARTERLY RESULTS OF OPERATIONS     
   
  The following table presents unaudited quarterly results in dollar amounts
and as a percentage of total revenues for each quarter during 1996 and for the
first quarter of 1997. The information has been prepared on a basis consistent
with the Company's annual consolidated financial statements and, in the
opinion of management, includes all adjustments, consisting only of
adjustments of a normal and recurring nature, which, in the opinion of
management, are necessary for a fair presentation of the information for such
periods. The Company's operating results have varied from quarter to quarter
in the past and may vary significantly in the future depending on factors such
as the size and timing of significant contracts, the mix of third party
products and the Company's proprietary products included in a particular
contract, customers' budgetary constraints, increased competition, the timing
of new product announcements and changes in pricing policies by the Company or
its competitors, market acceptance of new and enhanced versions of the
Company's products, changes in operating expenses and changes in general
economic factors. See "Risk Factors--Potential Fluctuations in Quarterly
Results."

LIQUIDITY AND CAPITAL RESOURCES
   
  Historically, the Company has satisfied its working capital requirements
through cash flows from its operations. The Company has two working capital
bank lines of credit aggregating $1,150,000. At March 31, 1997, no amounts
under these lines were outstanding. These lines of credit are renewable
annually in April, have been extended by the bank through July 31, 1997 and
bear interest at rates ranging from 0.5% to 1.5% over the bank's prime rate.
Both lines of credit are secured by accounts receivable, and one line of
credit requires a compensating cash balance of 50% of the outstanding amount
of the line. The Company believes that its cash flows from operations together
with the proceeds of this offering will be sufficient to meet its working
capital needs for at least the next 18 months. At March 31, 1997, the
$2,722,000 due to Alchut represents a three-year, non-interest bearing note
owed by Engineering for the transfer by Alchut of working capital at the end
of 1996.     
   
  Net cash provided by (used in) operating activities in 1994, 1995 and 1996
amounted to ($1.8 million), ($290,000) and $1.1 million, respectively. The
increase in cash provided by operating activities in 1996     
 
                                      25
<PAGE>
 
   
compared to 1995 and 1994 was principally due to the increase in net income to
$831,000 in 1996 from $493,000 and $84,000 in 1995 and 1994, respectively, the
reduction in inventory levels from $2.6 million in 1994 to $2.5 million in
1995 and $2.2 million in 1996 and changes in accounts payable to Alchut in all
periods.     
   
  Net cash used in investing activities increased by $794,000 in 1996 compared
to 1995. This increase was principally due to the purchase of property and
equipment of $349,000 in 1996 versus $129,000 in 1995 and the net cash paid
during 1996 for the purchase of Flam & Russell amounting to $573,000.     
   
  Net cash provided by (used in) financing activities in 1994, 1995 and 1996
amounted to $3.0 million, $91,000 and ($648,000), respectively. These changes
were principally due to net repayments on the Company's line of credit
agreements amounting to $150,000 in 1996 and fluctuations in the proceeds from
the note payable to Alchut in 1994 and 1995 in the amounts of $3.0 million and
$91,000, respectively, and a net repayment of $498,000 of the note payable to
Alchut in 1996.     
   
  During 1996, the Company spent or incurred an obligation for approximately
$1.0 million for the Flam & Russell acquisition, which was paid in its
entirety during May 1997. During 1997, the Company plans to spend up to a
maximum of $1.6 million on the AEMI acquisition, $800,000 of which will be
payable in cash, and to have capital expenditures of approximately $400,000, a
portion of which will be used to establish the Company's European office.     
   
  The Company has exposure to currency fluctuations as a result of billing
some of its contracts in foreign currency. When selling to customers in
countries with less stable currencies, the Company bills in U.S. dollars. For
the three months ended March 31, 1997, approximately 3% of the Company's
revenues was billed in currencies other than U.S. dollars. Substantially all
of the costs of the Company's contracts, including costs subcontracted to
Alchut, have been, and will continue to be, U.S. dollar-denominated except for
wages for Engineering employees which are denominated in local currency. The
Company intends to continue to enter into U.S. dollar-denominated contracts.
    
INFLATION AND SEASONALITY
 
  The Company does not believe that inflation or seasonality has had a
significant effect on the Company's operations to date.

INTRODUCTION
 
  The Company develops, markets and supports sophisticated automated microwave
test and measurement systems for the wireless communications, satellite,
automotive and aerospace/defense industries. Products such as cellular phones,
satellites, radio transmitters, global positioning system ("GPS") receivers
and guided missiles depend on the reliable and efficient transmission and
reception of microwave signals in order to communicate. By utilizing the
Company's systems to measure the critical performance characteristics of
microwave signals, wireless manufacturers and service providers within these
industries can improve quality and time-to-market, lower the risk of failure
and underperformance and reduce costs.
 
  Since its founding, the Company has expanded from distributing individual
microwave test and measurement components to providing a wide range of fully
integrated microwave test and measurement solutions. Components of an ORBIT/FR
automated microwave test and measurement system include proprietary software
and hardware products, which can be combined into standard or customized
configurations to meet a customer's specific needs. The Company believes that
its innovative proprietary systems, experienced staff, reputation for quality
and reliability, strong international presence and comprehensive customer
service give it a competitive advantage that will enable it to remain a
leading global supplier of microwave test and measurement systems to a growing
number of companies within the wireless communications, satellite, automotive
and aerospace/defense industries.
   
  The Company markets and sells its systems to customers in the United States
and throughout the world. Within the Company's targeted industries, the
Company's customers since January 1, 1994 have included manufacturers of
wireless systems and products, such as Motorola, Nokia and Ericsson;
manufacturers of systems and products that incorporate microwave technology,
such as Lockheed Martin, Hughes Aircraft, BMW and Boeing; and
telecommunications service providers that rely on microwave technology, such
as AT&T, NTT and Korea Mobile Telecom. The Company's customers also include
the United States government and several foreign governments. In 1996, none of
the Company's customers accounted for more than 5% of the Company's total
revenues. At March 31, 1997, the Company's backlog was approximately $8.5
million, compared to approximately $3.6 million at March 31, 1996.     
 
  The Company's objective is to strengthen its leadership position in
automated microwave test and measurement systems while developing products and
systems for a broader range of microwave applications. The principal elements
of the Company's strategy to reach its objective are: (i) offering
comprehensive solutions to customers, (ii) maintaining its technological
leadership, (iii) focusing on standard systems and proprietary off-the-shelf
products, (iv) pursuing growth in international markets and (v) leveraging its
technological expertise to expand into complementary markets.
 
INDUSTRY OVERVIEW
 
  The need for microwave test and measurement systems and products expanded
rapidly during the 1960's and 1970's in conjunction with the growth and
increased sophistication of the aerospace/defense industry in the United
States and Western Europe. In the last 20 years, this need for test and
measurement products and systems has expanded beyond aerospace/defense
applications to all aspects of modern telecommunications, including personal
wireless communications devices, satellite-based communications systems and
"smart" automobiles. This expansion has occurred in conjunction with a growing
desire among companies to focus on their core competencies and accordingly
outsource many non-core functions such as the development and manufacture of
microwave test and measurement systems.
 
  Within the wireless communications, satellite, automotive and
aerospace/defense industries, test and measurement products and systems are
used during all stages of a product's life cycle: product development, pre-
production qualification, production testing and product maintenance. Given
the broad scope of testing
 
                                      27

procedures, it is not uncommon for a manufacturer or service provider to own
and operate more than one microwave test and measurement system.
 
  WIRELESS COMMUNICATIONS. The wireless communications industry has grown
rapidly in recent years as a result of the development of cost-effective
digital technologies and the gradual global deregulation of the
telecommunications industry. Wireless communications products include
cellular/PCS handsets, pagers, field service/delivery equipment and
cellular/PCS base stations. Rapid growth within the wireless communications
industry is expected to continue in the future due to an increase in available
spectrum, the adoption of efficient new digital technologies and the
development of "smart" antennas. According to the Cellular Telecommunications
Industry Association ("CTIA"), there were over 44 million wireless subscribers
in the United States alone as of December 31, 1996, up 30.4% over 1995. The
CTIA also reports that wireless companies invested $8.4 billion in capital
improvements in 1996, up 65.2% over 1995, and that during 1996, 7,382 new cell
sites were deployed, 55.6% more than were deployed in 1995. The Company
believes that wireless communications growth in international markets has been
greater than growth experienced in the United States.
 
  Growing worldwide demand for wireless communications products and services
has generated a need among wireless manufacturers and service providers for
systems and products that address their specific microwave test and
measurement needs. These companies operate in highly-competitive, rapidly
changing markets in which the performance and reliability of their systems and
products are essential to achieve and maintain competitive advantages. The
accurate transmission and reception of microwave signals are fundamental to
the performance of wireless systems and products. To ensure the successful
transfer of voice or data from one point to another and to minimize poor
reception, cross talk and dropped calls, manufacturers and service providers
conduct extensive testing for signal quality, direction, strength and
interference.
   
  SATELLITE. Satellite-related markets have grown rapidly over the past
several years, driven by the emergence of advanced communication technologies
offering cost-effective global voice, video and data transmission, GPS,
internet access and tracking capabilities. Satellites provide several
advantages over terrestrial communications networks, including rapid
installation and deployment, no incremental cost as distances increase and
higher rates of data transmission. According to Euroconsult, a market research
firm, between 486 and 555 communications satellites are expected to be
manufactured between July 1996 and December 2006.     
 
  To ensure that satellite-based communications systems are effective and
reliable, it is essential that both satellites and "earth stations" transmit
and receive microwave signals accurately. The accuracy requirements for these
satellite systems are critical -- failure to detect a design error could
result in a satellite's "footprint" not covering its intended geographic area.
Satellite manufacturers cannot afford to make this kind of error since the
cost to manufacture, launch and insure a satellite can reach $200 million.
Accordingly, sophisticated microwave test and measurement systems are critical
to satellite and earth station manufacturers, as well as their subcontractors
and sub-assembly manufacturers, to ensure that their products work properly.
 
  AUTOMOTIVE. The world's major manufacturers of automobiles and automotive
sub-assemblies, driven by competitive pressures, are designing new generations
of "smart" cars and trucks that incorporate the latest communications and
safety devices including cellular/PCS, GPS-based direction-finding, data
transfer, digital TV and collision-avoidance systems. Each of these features
requires a specialized, highly-accurate microwave transmission and reception
system. To ensure the performance of these various systems and to assess how
they are impacted by the electromagnetic properties of the car itself,
automotive manufacturers must test the car and these devices as a unit using a
microwave test and measurement system designed for automotive applications.
 
  AEROSPACE/DEFENSE. The need within the aerospace/defense community for
accurate and secure communications and tracking systems led to the emergence
of microwave test and measurement companies in the 1960's. Despite cutbacks in
United States defense budgets in the late 1980's and early 1990's, microwave
test and measurement needs within the aerospace/defense industry are expected
to grow steadily for the
 
                                      28
<PAGE>

foreseeable future as a result of system upgrades on existing military
platforms, substantial new investments in non-U.S. military programs and the
expansion of civil aviation worldwide.
 
  The industry's tracking requirements, such as air traffic control and
missile guidance, led to the development of Radar Cross Section ("RCS") and
the test and measurement of radomes. RCS involves the transmission of
microwave signals towards a passive target, such as an aircraft or missile,
and then the creation of an "image" of the target by measuring the energy
reflected back towards the transmit source. Radome testing evaluates the
impact of a radome (the dome-shaped casing that is placed on the leading edge
of an aircraft or missile to protect the radar and direction-finding
equipment) on the microwave signals that pass through it.
 
THE ORBIT/FR SOLUTION
 
  ORBIT/FR provides its customers with flexible and reliable solutions for
their complex microwave test and measurement needs. The Company focuses its
efforts and resources on developing state-of-the-art microwave test and
measurement systems and products that incorporate specialized technologies and
expertise. The Company's customers have a need for microwave test and
measurement systems and products but often do not have the in-house
capabilities to develop, or the desire to develop, such systems and products
themselves. ORBIT/FR's systems and products provide customers with cost-
effective and user-friendly solutions to their microwave test and measurement
needs, thus allowing them to remain focused on their core competencies. The
Company's systems and products incorporate technological expertise developed
and acquired by the Company over many years.
 
  The Company offers a wide range of standard and custom microwave test and
measurement solutions for cellular/PCS handset testing, cellular base station
testing, satellite testing, automotive testing and specialized
aerospace/defense-related testing. The Company's products include test and
measurement software, microwave receivers, positioner subsystems, as well as
other microwave products, all of which are typically incorporated into the
Company's systems. The Company's proprietary software supports the Company's
own test and measurement products as well as those manufactured by third
parties. The Company's engineers and other technical staff use their broad
expertise to assess and understand their customers' specific microwave test
and measurement needs, process orders quickly, keep delivery time to a
minimum, provide comprehensive customer support and release new software on a
regular basis.
 
  The Company believes that its innovative proprietary systems, experienced
staff, reputation for quality and reliability, strong international presence
and comprehensive customer service give it a competitive advantage that will
enable it to remain a leading global supplier of microwave test and
measurement systems to a growing number of companies within the wireless
communications, satellite, automotive and aerospace/defense industries.
 
THE ORBIT/FR STRATEGY
 
  The Company's objective is to strengthen its leadership position in
automated microwave test and measurement systems while developing products and
systems for a broader range of microwave applications. The principal elements
of the Company's strategy to reach its objective are:
   
  OFFERING COMPREHENSIVE SOLUTIONS TO CUSTOMERS. As the need for microwave
test and measurement grows, new and existing customers increasingly desire to
purchase comprehensive, turnkey test and measurement systems from a single
provider. A turnkey system is one that has been assembled, integrated and
tested as a fully-operational system prior to a customer's use. The Company
addresses this desire by providing engineering and project management
services, by offering an increasingly broad product line and by maintaining
close relationships with outside component suppliers. Additionally, the
Company intends to acquire companies with complementary products and services
that can be integrated with the Company's existing or proposed products and
systems. For example, the Company expanded its product line with the
acquisition of Flam & Russell and will further expand its product line with
the acquisition of AEMI. By acquiring suppliers of key components of     
 
                                      29
<PAGE>
 
microwave test and measurement systems that the Company does not already
provide, the Company believes that it will be able to increase its overall
gross margin.
 
  MAINTAINING TECHNOLOGICAL LEADERSHIP. The Company believes that it has
sophisticated and diversified technological capabilities and intends to
maintain its technological leadership by continuously designing and developing
new software releases and hardware upgrades which offer greater performance
and higher precision.
 
  FOCUSING ON STANDARD SYSTEMS AND PROPRIETARY OFF-THE-SHELF PRODUCTS. Given
the diversified needs of the Company's customers, no two microwave test and
measurement systems will be identical. However, the Company seeks to keep the
costs of customization to a minimum by designing and delivering specific types
of systems that maximize the use of the Company's proprietary off-the-shelf
products. This approach enables the Company to optimize its margins while
offering its customers tailor-made solutions built around proven high-quality
and reliable products.
   
  PURSUING GROWTH IN INTERNATIONAL MARKETS. Approximately 52% of the Company's
revenues during 1996 were derived from international customers. The Company
believes that the growth of the international microwave test and measurement
marketplace over the next several years will be due in large part to worldwide
economic development, governmental policies aimed at improving the
communications infrastructure in developing countries and the increasing
globalization of commerce. The Company is devoting significant efforts to
increasing its share of the international market for microwave test and
measurement systems by strengthening and expanding its sales network through
the establishment of foreign sales and customer service centers and the
appointment of additional international sales representatives. In addition,
the Company believes it has a competitive advantage due to the duty-free
status of its products manufactured in Israel and sold into the European
Union. Approximately 92% of the Company's revenues in 1996 were denominated in
U.S. dollars, and the Company intends to continue to enter into U.S. dollar-
denominated contracts.     
 
  LEVERAGING TECHNOLOGICAL EXPERTISE TO EXPAND INTO COMPLEMENTARY MARKETS. The
Company intends to leverage its technological expertise in microwave test and
measurement systems to expand into complementary markets that the Company
believes offer high growth potential and where the Company's technology
provides competitive advantages. The Company has targeted Electromagnetic
Compatibility ("EMC") testing systems, Microwave Non-Destructive Testing
("NDT") systems and certain non-test and measurement microwave products as
potential future markets.
 
  EMC Testing. EMC testing addresses the unintentional interaction between
electronic products due to their electromagnetic radiation. Since this
radiation may adversely affect the operation of electronic equipment, FCC
guidelines in the United States, EMC and Low-Voltage directives in the
European Union and EMC guidelines in most other foreign countries regulate the
level of electromagnetic radiation emitted from these products and require
manufacturers of electronic products to perform EMC testing. The EMC testing
industry has grown rapidly over the past few years as a result of the
proliferation of electronic devices and the resultant transition from
voluntary regulatory "guidelines" to mandatory "directives." In 1996, the
market for EMC-related products and services was estimated at $1.3 billion in
Western Europe alone and is expected to grow by 20-30% annually for the
foreseeable future. The Company has identified certain test and measurement
needs within the overall EMC marketplace that require capabilities similar to
those which the Company has developed in the microwave test and measurement
field. The Company believes that its large customer base among electronic
equipment manufacturers would give it a significant advantage if it determined
to enter the EMC marketplace.
 
  Microwave Non-Destructive Testing. The field of NDT addresses the problem of
assessing the structural integrity of a product without having to damage or
destroy it. Current NDT methods employ ultrasonic and x-ray technologies which
have performance limitations and cannot be used under certain circumstances.
The Company believes that many of the techniques it has developed for
microwave test and measurement can be adapted to fill needs within the NDT
market.
 
 
                                      30
<PAGE>
 
  Other Microwave Products. The Company believes that opportunities exist to
apply the Company's core technologies to the design, manufacture and marketing
of products that incorporate microwave technology. The Company intends to
continue marketing its radial power combiners, amplifiers, antennas and
mixers, and plans to develop and sell additional microwave-based products in
the future. The Company believes its large customer base will give it a
competitive advantage in marketing these products.
 
SYSTEMS AND PRODUCTS
 
  Since its founding, the Company has expanded from distributing individual
microwave test and measurement components to providing a wide range of
microwave test and measurement solutions. Components of an ORBIT/FR automated
microwave test and measurement system include proprietary software and
hardware products which can be combined into standard or customized
configurations to meet customers' specific needs. One of the Company's
principal strengths is its experienced design team that solves complex
technical and practical problems. A typical automated microwave test and
measurement system is illustrated below:
       

[A PICTURE APPEARS HERE OF AN AUTOMATED MICROWAVE TEST AND MEASUREMENT SYSTEM,
 WHICH INCLUDES A PERSONAL COMPUTER, A MICROWAVE RECEIVER, A SIGNAL SOURCE, A
            POWER CONTROL UNIT, A PROBE AND A DEVICE UNDER TEST.]
 
  MICROWAVE TEST AND MEASUREMENT SYSTEMS. The Company designs, manufactures
and markets automated microwave test and measurement systems. In addition to
providing most of these systems' component parts, the Company also integrates
the systems and trains its customers in use of the systems. While most
customers purchase fully integrated turnkey microwave test and measurement
systems, the Company also sells its hardware and software products
individually as replacement parts or components of custom-designed systems.
The Company offers seven types of microwave test and measurement systems. The
first, antenna measurement systems, are generic systems that can be adapted
for many uses, and the other types are designed and sold in
 
                                      31
<PAGE>
 
response to well-defined microwave test and measurement needs within specific
industries. Prices for a typical ORBIT/FR system range from $50,000 to
$500,000, but large systems have sold for as much as $2.5 million.
 
  Antenna Measurement Systems. All products and systems that receive or
transmit microwave signals rely on antennas. Accordingly, items such as
microwave radios, GPS receivers, field service/delivery equipment, satellite
earth stations and guided missiles need to have their antennas tested to
ensure satisfactory performance characteristics. The Company's antenna
measurement systems offer both manufacturers and service providers user-
friendly and cost-effective solutions for their antenna measurement needs. The
systems test for signal quality, direction, strength and interference and can
be adapted to perform testing in each of the stages of a product's life:
development, qualification, production and maintenance. While antenna
measurement systems differ significantly from one application to another, all
of the Company's systems incorporate a personal computer running specialized
proprietary software, a microwave receiver, a positioning subsystem, and at
least one additional antenna or probe. The systems can be designed for use in
a wide variety of different test environments, ranging from a small anechoic
chamber to an outdoor range covering several acres. The Company offers three
types of antenna measurement methods:
 
  . Far-field:Traditional method generally used outdoors
 
  . Near-field:Cost-effective indoor method using mathematical conversion
  tools
 
  . Compact Range:High-end indoor method using a microwave reflector
 
  The Company also has developed advanced systems that combine these
measurement methods, such as far-field and near-field, in a single chamber.
   
  Cellular/PCS/Pager Systems. ORBIT/FR believes it is a leader in the design
and delivery of high-performance test and measurement systems for
manufacturers of cellular/PCS handsets and pagers. The Company has developed a
standard system based on its spherical near-field technology that the Company
sells as a turnkey off-the-shelf product. The system consists of the Company's
software, receiver and positioning subsystem built into a small anechoic
chamber together with a mannequin. The positioning subsystem allows a probe to
trace a sphere around the handset or pager held by the mannequin, thus fully
sampling the complete microwave properties of the device under test.     
   
  Cellular/PCS Base Station Systems. The Company develops and sells test and
measurement systems used to assess the microwave performance characteristics
of cellular/PCS base stations. These systems enable cellular/PCS base station
antenna manufacturers to design and build efficient and reliable products, and
they allow wireless communications service providers to monitor more
efficiently the performance of their base stations. The existing system design
is based on the Company's cylindrical near-field technology and is designed
for indoor use. Additionally, the Company is investigating the use of an
outdoor mobile testing system for cellular/PCS base stations.     
 
  Satellite Systems. The Company develops and sells microwave test and
measurement systems for satellites which test many aspects of satellite
performance including beam location (to assess the satellite's "footprint"),
channel purity and intermodulation, gain, G/T, pattern, EIRP and TMA/TDMA
microwave timing. These systems also test the transmit and receive
characteristics of the active array antennas used on most modern satellites
and can have the ability to identify and diagnose malfunctions within these
complex antennas. The Company's satellite systems utilize either near-field or
compact range technology. Both technologies are equally effective from a test
and measurement viewpoint, but each offers certain benefits. A near-field
system offers diagnostic capabilities and is generally less expensive than a
comparably equipped compact range system, but a compact range system is faster
and easier to use.
 
  Automotive Systems. ORBIT/FR believes it is a leader in the design and
delivery of high-performance test and measurement systems for automobile
manufacturers and manufacturers of automotive sub-assemblies. The Company's
systems incorporate both near-field and far-field technologies and are thus
capable of microwave sampling over a wide range of frequencies. A typical
system includes a large mechanical arm that sweeps over a large turntable. The
car being tested rests on the turntable, and both the turntable and the
mechanical arm are set in motion based upon instructions received from the
Company's measurement software. The systems' broad capabilities are essential
given a growing trend by automobile manufacturers to integrate advanced
microwave
 
                                      32
<PAGE>
 
technologies such as cellular/PCS, GPS-based direction-finding, data transfer,
digital TV and collision-avoidance systems into their "smart" cars.
 
  RCS Systems. The Company's Radar Cross Section ("RCS") measurement systems
transmit microwave signals towards a passive target and then measure the energy
reflected back towards the transmit source. In an RCS system, the passive
target is typically a model or full scale aircraft or missile that is mounted
on a special "low-RCS" testing pylon capable of rotating the target. Data
collected at various rotation angles and frequencies can be processed to form
an electromagnetic "image" of the target. This type of information enables the
design engineer to assess more accurately the detailed radar signature of the
target. The Company believes that it is a market leader in this field.
 
  Radome Systems. A radome is a dome-shaped casing that is placed on the
leading edge of an aircraft or missile to protect the radar and direction-
finding equipment. A radome is typically manufactured using fiberglass or other
materials that are designed to be "transparent" to microwave signals. Testing
is performed periodically to ensure that microwave signals are not degraded or
deflected as they pass through the radome. The Company's systems are designed
to measure radome performance by analyzing the path of microwave signals as
they pass through the radome and then comparing it to the propagation path when
the radome is not present. Radome systems use far-field measurement methods but
rely on high positioning accuracy normally required by near-field systems.
 
  Custom Systems. From time to time, the Company designs and manufactures
custom microwave test and measurement systems for a wide variety of uses and
applications. To date, most of these systems have been built for the United
States government. The Company's broad microwave and antenna expertise has
enabled it to obtain these contracts, and the Company intends to bid for
similar jobs in the future if the expertise gained in designing such systems is
deemed to be of strategic value to the Company.
 
  MICROWAVE TEST AND MEASUREMENT SOFTWARE PRODUCTS. ORBIT/FR offers automatic
measurement software for microwave test and measurement systems. The Company's
software products are Windows-based programs that provide the customer with a
consistent user-friendly interface with the test and measurement system. The
software products have a robust and modular structure that enables the Company
to easily add features for current and future customers. The software uses far-
field and/or near-field algorithms to generate accurate results, and the
computational methodologies used have gained acceptance throughout the
microwave test and measurement community. The software supports the Company's
own measurement equipment as well as equipment manufactured by third parties.
The Company's software products are designed to be "off-the-shelf" but are
versatile and can be customized by the Company's or the customer's technical
personnel to suit specific needs. The Company has delivered over 300 software
installations worldwide in the price range of $20,000-50,000 each. The Company
believes that its software products are the industry standard.
 
  While software can vary between systems, it always consists of three primary
modules: data acquisition, data analysis and report writing. The software's
data acquisition module records actual measurements as it controls the
microwave measurement equipment, the positioning subsystem, and often the
source antenna and/or the antenna being measured. Variables such as frequency,
power level, amplitude, phase, rotary and/or linear motion, polarization,
transmit/receive switching, electrical beam pointing and polarization switching
are all controlled by the Company's measurement software. The multidimensional
results obtained are stored in a computer file for subsequent analysis. The
software's data analysis module processes the acquired data using sophisticated
microwave and signal processing algorithms developed by the Company and the
National Institute of Standards and Technology ("NIST"). The data analysis
module transforms the acquired data into easily-understood numerical
information and graphic representations, thus providing the customer with the
data required to satisfy its internal requirements and those of its own
customers. The software's report writing module can be customized to meet each
customer's needs.
 
  MICROWAVE RECEIVERS. The microwave receiver is the device in the automated
microwave test and measurement system that measures the microwave signals
received from the antenna or device under test or,
 
                                       33
<PAGE>
 
alternatively, from the antenna collecting the backscatter from an RCS target.
The Company's microwave receivers convert and digitize the signals to put them
into a computer compatible format. They are capable of simultaneously
measuring up to four channels ranging in frequency from 50 MHz to 110 GHz. The
Company believes that its microwave receivers have a high degree of accuracy
and are easy to use. As part of its "Channel Partner" relationship with
Hewlett Packard, the Company uses HP as its preferred source for microwave
receivers incorporated into the Company's test and measurement systems. While
this arrangement with HP has led to a decrease in sales of the Company's own
receivers, the Company believes that the benefits of its relationship with HP,
such as increased visibility, market access and product performance,
substantially outweigh the costs.
 
  POSITIONER SUBSYSTEMS. The positioner subsystem is the collection of
equipment that holds the device under test and causes it to be moved according
to the needs of the test. A typical positioner subsystem may include the
following components:
 
  Positioners. A positioner is the item upon which the device under test is
placed while it is being tested. The Company's positioners are rugged, yet
highly precise, devices that adjust themselves in accordance with the
positioning instructions received from the measurement software. Special
circuitry and mechanical design features built into the positioner enable the
data acquired from the antenna under test to travel efficiently through the
positioner to the computer to be analyzed. The Company's simple positioners
rotate around a single axis, while the Company's more elaborate positioners
incorporate up to three axes. An automated microwave test and measurement
system requires one or more positioners. The Company offers over 200 different
positioner models and believes that its positioners are among the most
accurate in the market.
 
  Positioner Controllers and Power Control Units. The Company manufactures
positioner controllers and power control units ("PCUs") as well as models that
combine these two products into one box. Working together, the positioner
controller and the PCU act as the "translators" between the microwave software
and the positioner. The positioner controller receives digital instructions
from the microwave software and translates them into analog signals understood
by the PCU. These analog signals are then amplified by the PCU to provide
precisely calibrated DC power to the positioner's electric motors, which then
operate at a user-defined speed to move the antenna or device under test
through the desired positions. The Company offers four positioner controller
models, two PCU models and four models that combine both positioner controller
and PCU.
   
  Planar Scanners. A planar scanner is a rectangular device that enables a
probe antenna to be moved along an x- and y-axis so that its position at any
time is known and can be exactly replicated. Planar scanners are typically
mounted vertically to enable the probe to be moved throughout the height and
width dimensions of the scanner. Scanners enable test engineers to accurately
and reliably analyze many aspects of the microwave signals radiating from the
antenna or device under test. The Company offers 24 standard scanners ranging
in size from 3 feet x 3 feet to 25 feet x 80 feet.     
 
  Pylons and Model Towers. Pylons and model towers are used in many microwave
test and measurement applications and range in size from very large to very
small. Large pylons can carry substantial loads in indoor or outdoor
environments, and certain models can even support a full-sized aircraft.
Pylons are almost always used in RCS systems.
 
  OTHER MICROWAVE PRODUCTS. The Company has developed several microwave
products used in the larger microwave industry.
 
  Radial Power Combiners. The Company's radial power combiners offer a highly-
efficient electromagnetic mechanism to combine several identical low-energy
signals together to make a single high-energy signal. Radial power combiners
have many uses, but their most common application is in high-power microwave
transmitters.
   
  Microwave absorber. Following the acquisition of AEMI contemporaneously with
this offering, the Company will add microwave absorber material to its product
line. This material consists of specially-treated     
 
                                      34
<PAGE>
 
   
polyurethane foam which absorbs electromagnetic waves and is an important
component of most microwave test and measurement systems.     
 
  Antennas, Probes and Other Microwave Accessories. The Company designs and
manufactures antennas, probes and other microwave accessories. These products
are used in the Company's microwave test and measurement systems, and they are
also sold to customers as stand-alone items.
 
SALES, MARKETING AND CUSTOMER SUPPORT
   
  The Company markets and sells its products in the United States through three
regional sales managers and through two independent sales representatives that
target specific geographic and strategic markets. Internationally, the Company
has established sales and customer service centers in Israel and Germany and
has distributors and representatives for sales, marketing and customer support
in Austria, China, Denmark, France, Germany, India, Italy, Japan, Singapore,
South Korea, Spain, Sweden, Switzerland, Taiwan and the United Kingdom.     
 
  The Company's engineers and other technical staff support the efforts of the
sales force. Since a customer's engineers typically play an important role in
the procurement decision, the Company's engineers work closely with them to
help them understand the advantages of the Company's products and systems.
Additional business from existing customers is pursued through the joint
efforts of both the sales force and the engineers and other technical staff who
have worked closely with the customer's engineers and who understand the
customer's needs. If a customer has already purchased a microwave test and
measurement system from ORBIT/FR, the Company believes it has an advantage over
competitors in obtaining orders for system upgrades as well as any additional
systems that the customer may wish to purchase at a later date. Typically, a
substantial portion of the Company's revenues in a given year is generated by
customers for whom the Company has previously provided products or systems.
 
  The Company generates sales leads for new customers through referrals from
existing customers and other industry suppliers, its reputation in the
industry, advertising in trade publications and on the World Wide Web and
participation in conferences and trade shows. In addition, the Company is in
the process of establishing marketing alliances with two major manufacturers of
products and systems that incorporate microwave technology, pursuant to which
the Company will provide test and measurement system upgrades and support free
of charge in return for referral business. As a Hewlett Packard "Channel
Partner," the Company receives referrals and recommendations from HP's
worldwide sales force, and the Company believes that it thereby obtains greater
visibility in the microwave test and measurement market.
 
  The Company devotes significant resources to provide comprehensive customer
support. Customer support is provided under warranty for the first year on all
products sold by ORBIT/FR. Beyond the first year, customer support on products
sold by ORBIT/FR is provided on an as-needed basis. The Company also provides a
technical support line and, for an additional fee, on-site and in-house
training for all of its products and systems. The Company encourages its
employees to be customer service-oriented because it relies to a large degree
on its reputation to attract and retain customers. Furthermore, the Company
believes that its comprehensive customer support program gives it a competitive
advantage in the microwave test and measurement market.
 
CUSTOMERS
   
  The Company has over 1,000 installations with customers in the wireless
communications, satellite, automotive and aerospace/defense industries. In
1994, Raytheon, and in 1995, Matra Marconi, each accounted for more than 10% of
the Company's total revenues; however, the Company believes the loss of either
customer would not have a material adverse effect on the Company's revenues. In
1996, none of the Company's customers accounted for more than 5% of the
Company's total revenues. Representative customers that have purchased

  The Company's customers are located in the Americas (the United States,
Canada, Brazil and Argentina), Europe (the United Kingdom, France, Germany,
Italy, Holland, Spain, Austria, Denmark, Poland, Finland, Norway, Sweden,
Switzerland and Portugal) and throughout the rest of the world (Japan, Korea,
China, Thailand, Taiwan, Singapore, Indonesia, Israel, Australia and South
Africa).
 
PRODUCTION AND SUPPLIERS
 
  The Company's engineers, based in both Horsham, Pennsylvania and Israel, are
responsible for product design and development and for overseeing the
production of the Company's products. While the Company maintains a production
facility in Horsham, most of the production of the Company's products is
performed by subcontractors. Alchut is currently the Company's principal
subcontractor for electro-mechanical production, primarily in connection with
the manufacturing of positioners. The Company believes that Alchut currently
offers the best available combination of quality, reliability and price. After
the expiration of its one-year service contract with Alchut, the Company has
the right to select any other subcontractor. See "Certain Transactions."
 
  While the Company produces most of the component parts for its microwave
test and measurement systems, it purchases certain components from outside
vendors for turnkey microwave test and measurement systems, including personal
computers, shielded enclosures and microwave absorbers. The acquisition of
AEMI will enable the Company to add microwave absorbers to its product line,
and part of the Company's strategy is to seek future acquisitions that will
further reduce its dependence on outside suppliers.
 
BACKLOG
   
  At March 31, 1996 and 1997, the Company's backlog was approximately $3.6
million and $8.5 million, respectively. The Company includes in backlog only
those orders for which it has received and accepted a completed purchase
order. Such orders are generally subject to cancellation by the customer with
payment of a specified charge. The delivery lead time on the Company's
products and systems averages approximately five months, but can be as short
as a few days and as long as 12 months. Because of the possibility of customer
changes in delivery schedules, cancellation of orders and potential shipment
delays, the Company's backlog as of any particular date may not be
representative of actual sales for any succeeding period.     
 
                                      36

RESEARCH AND DEVELOPMENT
   
  The Company believes that its future success depends on its ability to adapt
to rapidly changing technological circumstances within the industries it serves
and to continue to meet the needs of its customers. Accordingly, the timely
development and introduction of new products is essential to maintain the
Company's competitive position. The Company develops all of its products in-
house and currently has a research and development staff which includes 14
engineers. A significant portion of the Company's research and development
efforts has been conducted in direct response to the specific requirements of
customers' orders, and, accordingly, such amounts are included in the cost of
sales when incurred and the related funding is included in net revenues at such
time. Revenues for customer-funded research and development during 1994, 1995
and 1996 were approximately $472,000, $482,000 and $520,000, respectively, and
approximately $20,000 and $127,000, respectively, for the three months ended
March 31, 1996 and 1997. In addition, the Company invested $237,000, $239,000
and $581,000 during 1994, 1995 and 1996, respectively, and approximately
$97,000 and $219,000 for the three months ended March 31, 1996 and 1997,
respectively, on independent research and development, which is not directly
funded by a third party. Customer-funded research and development contains a
profit component and is therefore not directly comparable to independent
research and development.     
 
  The Company continues to benefit from research and development grants from
the Israeli government through the Chief Scientist program, from the United
States government through the SBIR program and through BIRD, a joint United
States/Israeli government program. While the Company has already received
significant benefits from these programs throughout the initial development
stages of its core technology base, the Company believes that its business,
operating results and financial condition would not be materially adversely
affected if the Company were to lose its ability to obtain research and
development funding through these programs in the future. The Company plans to
leverage this technology base to develop additional products for commercial
applications.
 
COMPETITION
 
  The Company believes that its current systems and products compete
effectively with the systems and products offered by its competitors on the
basis of product functionality, speed and accuracy, reliability, price, ease of
use and technical support. The market for automated microwave test and
measurement products, systems and services, however, is highly competitive and
is characterized by continuing advances in products and technologies. In
general, competition in this market comes from major microwave test and
measurement vendors, some of which have a longer operating history,
significantly greater financial, technical and marketing resources, greater
name recognition and a larger installed customer base than the Company. These
companies also have established relationships with current and potential
customers of the Company. The Company also competes, on a limited basis, with
the internal development groups of its existing and potential customers, many
of whom design and develop parts of their own microwave test and measurement
systems. The Company's business, operating results and financial condition
could be materially adversely affected by such competition. The Company's
primary competitors in the microwave test and measurement market are Scientific
Atlanta, Nearfield Systems, Aeroflex, System Planning Corporation and
Rantec/ESCO.
 
PROPRIETARY RIGHTS
 
  The Company is heavily dependent on its proprietary technology. The Company
relies on a combination of confidentiality agreements with its employees,
license agreements, copyrights, trademarks and trade secret laws to establish
and protect rights to its proprietary technology. The Company does not hold any
material patents. All of the Company's software is shipped with a security lock
which limits software access to authorized users. Generally, the Company does
not license or release its source code. Effective copyright and trade secret
protection of the Company's proprietary technology may be unavailable or
limited in certain foreign countries.
 
EMPLOYEES
 
  As of March 31, 1997, the Company had a total of 67 employees, including 22
in software and research and development, 16 in engineering and program
management, 12 in sales, marketing and customer support
 
                                       37

services, eight in production and nine in administration. Fifty-two employees
are located at the Company's headquarters in Horsham, Pennsylvania, 14 are
located in Israel and one is located in Germany. None of the Company's
employees is represented by a collective bargaining agreement, nor has the
Company experienced any work stoppage. The Company considers its relations with
its employees to be good.
 
LITIGATION
 
  The Company is not a party to any litigation and is not aware of any
threatened litigation, unasserted claims or assessments that could have a
material adverse effect on the Company's business, operating results or
financial condition.
 
FACILITIES
 
  The Company occupies approximately 20,000 square feet of space at its
headquarters in Horsham, Pennsylvania under a lease expiring in October 1997.
Upon expiration of the lease, the Company anticipates moving to a 40,000 to
50,000 square foot facility in the same vicinity. The current annual base rent
is approximately $179,000. The Company also maintains an engineering facility
in Israel and is in the process of establishing a technical support and program
management center in Germany. The Company's current aggregate annual rental
expenses for these additional facilities are approximately $60,000.

1997 EQUITY INCENTIVE PLAN
 
  On March 17, 1997, the Board of Directors adopted and the Company's
stockholder approved the Company's 1997 Equity Incentive Plan (the "Incentive
Plan"). The purposes of the Incentive Plan are to attract and retain key
employees and certain other persons who are in a position to make significant
contributions to the success of the Company, to reward these employees and
other persons for their contributions, to provide additional incentive to these
employees and other persons to continue making similar contributions and to
further align the interests of these employees and other persons with those of
the Company's stockholders. To achieve these purposes, the Incentive Plan
permits grants of incentive stock options ("ISOs"), options not intended to
qualify as incentive stock options ("Non-ISOs"), stock appreciation rights
("SARs"), restricted and unrestricted stock awards, performance awards, loans
and supplemental cash awards and combinations of the foregoing (all referred to
as "Awards").
   
  The Incentive Plan permits Awards to be granted for a total of 800,000 shares
of the Company's Common Stock. Shares issuable under Awards that terminate
unexercised, shares issuable under Awards that are payable in stock or cash but
are paid in cash and shares issued but later forfeited will be available for
future Awards under the Incentive Plan. The Company has granted, effective upon
the completion of this offering, options to purchase 492,300 shares of Common
Stock at the Offering Price. By their terms, these options are not exercisable
until 24 months after the completion of this offering.     
 
  All current and future employees of the Company, and other persons who, in
the opinion of the Board of Directors, are in a position to make significant
contributions to the success of the Company, such as consultants and non-
employee directors, are eligible to receive Awards under the Incentive Plan.
 
  The Incentive Plan is administered by the Board of Directors, which
determines, among other things and subject to certain conditions, the persons
eligible to receive Awards, the persons who actually receive Awards, the type
of each Award, the number of shares of Common Stock subject to each Award, the
date of grant, exercise schedule, vesting schedule and other terms and
conditions of each Award, whether to accelerate the exercise or vesting
schedule or waive any other terms or conditions of each Award, whether to amend
or cancel an Award and the form of any instrument used under the Incentive
Plan. The Board of Directors has the right to adopt rules for the
administration of the Incentive Plan, settle all controversies regarding the
Incentive Plan or any Award, and construe and correct defects and omissions in
the Incentive Plan or any Award. The Incentive Plan may be amended, suspended
or terminated by the Board of Directors, subject to certain conditions,
provided
 
                                       42
<PAGE>
 
that stockholder approval will be required whenever necessary for the
Incentive Plan to continue to satisfy the requirements of certain securities
and tax laws, rules and regulations.
 
  Recipients of stock options under the Incentive Plan will have the right to
purchase shares of Common Stock at an exercise price, during a period of time
and on such other terms and conditions as are determined by the Board of
Directors. For ISOs, the recipient must be an employee, the exercise price
must be at least 100% (110% if issued to a 10% or greater stockholder of the
Company) of the fair market value of the Company's Common Stock on the date of
grant and the term cannot exceed ten years (five years if issued to a 10% or
greater stockholder of the Company) from date of grant. If permitted by the
Board of Directors and subject to certain conditions, an option exercise price
may be paid by delivery of shares of the Company's Common Stock that have been
outstanding, a promissory note, a broker's undertaking to promptly deliver the
necessary funds or by a combination of those methods. If permitted by the
Board of Directors, options (other than those granted in tandem with SARs) may
be settled by the Company, paying to the recipient, in cash or shares of
Common Stock (valued at the then fair market value of the Company's Common
Stock), an amount equal to such fair market value minus the exercise price of
the option shares.
 
  SARs may be granted under the Incentive Plan either alone or in tandem with
stock options. Generally, recipients of SARs are entitled to receive, upon
exercise, cash or shares of Common Stock (valued at the then fair market value
of the Company's Common Stock) equal to such fair market value on the date of
exercise minus such fair market value on the date of grant of the shares
subject to the SAR, although certain other measurements also may be used. A
SAR granted in tandem with a stock option is exercisable only if and to the
extent that the option is exercised.
 
  The Incentive Plan provides for restricted and unrestricted stock awards.
Stock awards allow the recipient to acquire shares of the Company's Common
Stock for their par value or any higher price determined by the Board of
Directors. In the case of restricted stock awards, the shares acquired are
subject to a vesting schedule and other possible conditions determined by the
Board of Directors.
 
  The Incentive Plan provides for performance awards entitling the recipient
to receive stock options, stock awards or other types of Awards conditional
upon achieving performance goals determined by the Board of Directors.
Performance goals may involve overall corporate performance, operating group
or business unit performance, personal performance or any other category of
performance determined by the Board of Directors. Financial performance may be
measured by revenue, operating income, net income, earnings per share, Common
Stock price, price-earnings multiple or other financial factors determined by
the Board of Directors.
 
  Under the Incentive Plan, loans or supplemental cash awards may be granted
to recipients of Awards to help defray taxes due as a result of the Awards.
The terms and conditions of loans and supplemental cash awards, including the
interest rate, which may be zero, and whether any loan will be forgiven, are
determined by the Board of Directors.
 
  Generally, upon termination of a recipient's employment or other
relationship with the Company, stock options and SARs remain exercisable for a
period of three months (one year if termination is due to death or disability)
to the extent that they were exercisable at the time of termination, except as
otherwise agreed between the employee and the Company, unvested shares under
outstanding restricted stock awards vest immediately except in the case of a
voluntary resignation or termination for cause (as defined in the Incentive
Plan). Stock options, SARs and other Awards that are not exercisable at the
time of termination automatically terminate, and payments or benefits under
deferred stock awards, performance awards and supplemental cash awards that
are not irrevocably due at the time of termination are forfeited.

shares of Engineering and a three-year, non-interest bearing note in the
principal amount of $2,722,000. In December 1996, Alchut transferred or caused

Technologies and Engineering in exchange for 4,000,000 shares of Common Stock
of the Company. See "The Company."
   
  The Company, Engineering and Alchut have entered into a one-year services
agreement, commencing January 1, 1997, pursuant to which: (i) Alchut will

compensation for the provision of its administrative services to Engineering,
(ii) cost of the production services plus 5% as compensation for the provision
of its production services to Engineering and (iii) $22.80 per square foot per
year as rent (approximately $51,000 for 1997). The Company will receive (i)
reimbursement for the cost of the administrative services it provides to Alchut
and (ii) $2,000 per month as rent. The compensation to be received by the
Company and Alchut for the provision of office space includes all taxes,
utilities and maintenance. After the expiration of the one-year term of the
agreement, Alchut's and the Company's compensation is subject to negotiation,
and the entire agreement is terminable on 90 days notice.     
   
  The Company has acted as a distributor for certain systems manufactured by

three months ended March 31, 1996 and 1997, the Company's commission revenues
were approximately $43,000, $342,000, $137,000 and $13,000 and $0,

December 31, 1994, 1995 and 1996 and for the three months ended March 31, 1996
and 1997 are approximately $1,492,000, $1,423,000, $1,496,000 and $298,000 and
$323,000, respectively, relating to the production services provided by Alchut.

                           DESCRIPTION OF SECURITIES
 
  Under the Company's Amended and Restated Certificate of Incorporation, the
authorized capital stock of the Company is 12,000,000 shares, consisting of
10,000,000 shares of Common Stock, $0.01 par value per share, and 2,000,000
shares of undesignated Preferred Stock, $0.01 par value per share. As of the
date of this offering, 4,000,000 shares of Common Stock are issued and
outstanding and held of record by Alchut. Upon the completion of this offering,
6,094,118 shares of Common Stock will be issued and outstanding (assuming the
issuance of a maximum of 94,118 shares of Common Stock in connection with the
acquisition of AEMI).
 
COMMON STOCK
 
  The holders of Common Stock are entitled to one vote per share on all matters
to be voted on by the stockholders. Subject to preferences that may be
applicable to outstanding shares of Preferred Stock, if any, the holders of
Common Stock are entitled to receive ratably such dividends as may be declared
from time to time by the Board of Directors out of funds legally available
therefor. In the event of the liquidation, dissolution or winding up of the
Company, the holders of Common Stock are entitled to share ratably in all
assets remaining after payment of liabilities, subject to prior liquidation
rights of Preferred Stock, if any, then outstanding. The Common Stock has no
preemptive conversion rights or other subscription rights. There are no
redemption or sinking funds provisions applicable to the Common Stock. All
outstanding shares of Common Stock are fully paid and non-assessable, and the
shares of Common Stock to be outstanding upon completion of this offering will
be fully paid and non-assessable.
 
PREFERRED STOCK
   
  Upon completion of this offering, no shares of Preferred Stock will be
outstanding. The Board of Directors will have the authority to issue up to
2,000,000 shares of Preferred Stock in one or more series and to fix the
rights, preferences, privileges and restrictions granted to or imposed upon
such Preferred Stock, including dividend rights, conversion rights, terms of
redemption, liquidation preferences, sinking fund terms and the number of
shares constituting any series or the designation of such series, without any
further vote or action by the stockholders unless otherwise required by law.
The Board of Directors can issue Preferred Stock with voting, dividend,
conversion, redemption and liquidation rights which could adversely affect the
rights of the holders of Common Stock. The issuance of Preferred Stock could
have the effect of delaying, deferring or preventing a change in control of the
Company. The Company has no present plan to issue any shares of Preferred
Stock.     
 
INDEMNIFICATION OF OFFICERS AND DIRECTORS
 
  As permitted by the DGCL, the Company's Amended and Restated Certificate of
Incorporation provides that no director of the Company will be personally
liable to the Company or its stockholders for monetary damages for breach of
fiduciary duty as a director, except (i) for any breach of the directors' duty
of loyalty to the Company or its stockholders, (ii) for acts or omissions not
in good faith or involving intentional misconduct or a knowing violation of
law, (iii) with respect to certain unlawful payments of dividends or unlawful
stock repurchases or redemptions as provided in Section 174 of the DGCL or (iv)
for any transaction from which the director derives any improper personal
benefit. In addition, the Company's Bylaws provide that the Company may
indemnify any director or officer, to the fullest extent permitted by the DGCL,
who was or is a party to any action or proceeding by reason of his or her
services to the Company.
 
DELAWARE LAW
 
  The Company is subject to the provisions of Section 203 of the DGCL. In
general, Section 203 prohibits a public 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 business combination is approved in a
prescribed manner. Generally, a "business combination" includes mergers, asset
sales and other transactions resulting in a financial benefit to the
stockholder. An "interested
 
                                       46
<PAGE>
 
stockholder" is a person who, together with his affiliates and associates, owns
(or within three years, did own) 15% or more of a corporation's voting stock.
The statute could have the effect of delaying, deferring or preventing a change
in control of the Company.
 
TRANSFER AGENT AND REGISTRAR
 
  The transfer agent and registrar for the Common Stock is American Stock
Transfer & Trust Company, New York, New York.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Upon completion of this offering, the Company will have outstanding 6,094,118
shares of Common Stock. Of these shares, the 2,000,000 shares sold in this
offering will be freely transferable by persons other than "affiliates" of the
Company without restriction or further registration under the Securities Act.
The remaining 4,094,118 shares of Common Stock outstanding, 4,000,000 of which
are owned by Alchut and a maximum of 94,118 of which will be issued in
connection with the acquisition of AEMI, are "restricted securities"
("Restricted Shares") within the meaning of Rule 144 under the Securities Act
and may not be sold unless registered under the Securities Act or an exemption
from registration is available, including the exemption afforded by Rule 144.
 
  Alchut and the Company's executive officers and directors have entered into
"lock-up" agreements with the Representatives of the Underwriters pursuant to
which neither Alchut nor such persons will, directly or indirectly, offer,
sell, contract to sell, pledge, grant any option for the sale of or otherwise
dispose of any shares of Common Stock or any securities convertible into, or
exercisable or exchangeable for, any shares of Common Stock for a period of 180
days after the date of this Prospectus without the prior written consent of the
Representatives, other than in certain private transactions in which each
transferee acquiring an interest in such Common Stock during such 180-day
period agrees in writing to be bound by such agreement. After such 180-day
period, the 4,000,000 shares of Common Stock held by Alchut will be eligible
for sale in the public market in reliance upon Rule 144 subject to the
restrictions contained therein. The stockholders of AEMI have agreed with the
Company that they will not offer, sell or otherwise dispose of the maximum of
94,118 shares of Common Stock issued in connection with the acquisition of AEMI
for a period of two years after the closing date of such acquisition. After
such two-year period, the maximum of 94,118 shares held by such stockholders
will be eligible for sale under Rule 144 subject to the restrictions contained
therein. After 180 days from the date of this Prospectus, the Company intends
to register under the Securities Act 800,000 shares of Common Stock reserved
for awards under the Company's Incentive Plan.
 
  Rule 144, as currently in effect, provides that an affiliate of the Company
or a person (or persons whose shares are aggregated) who has beneficially owned
Restricted Shares for at least one year but less than two years is entitled to
sell, commencing 90 days after the date of this Prospectus, within any three-
month period a number of shares that does not exceed the greater of one percent
of the then outstanding shares of Common Stock (60,941 shares immediately after
the completion of this offering) or the average weekly trading volume in the
Common Stock during the four calendar weeks preceding such sale. Sales under
Rule 144 also are subject to certain manner-of-sale provisions, notice
requirements and the availability of current public information about the
Company. However, a person who is not an "affiliate" of the Company at any time
during the three months preceding a sale, and who has beneficially owned
Restricted Shares for at least two years, is entitled to sell such shares under
Rule 144(k) without regard to the limitations described above.
 
  Since there has been no public market for the Company's shares of the Common
Stock, the Company is unable to predict the effect that sales made pursuant to
Rule 144 or otherwise may have on the prevailing market price at such times for
shares of the Common Stock. Nevertheless, sales of a substantial amount of the
Common Stock in the public market, or the perception that such sales could
occur, could adversely affect market prices. See "Risk Factors -- Shares
Eligible for Future Sale."
 
  Under the Company's Incentive Plan, the Company has granted, effective upon
the completion of this offering, options to purchase 492,300 shares of Common
Stock at the Offering Price. By their terms, these options are not exercisable
until 24 months after the completion of this offering. In addition, there are
307,700 shares available for options which the Company may grant in the future
under the Incentive Plan.

</TABLE>
 
  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent. The nature of the Underwriters'
obligation is such that they are committed to purchase all shares of Common
Stock offered hereby if any of such shares are purchased.
 
  The Company has been advised by the Underwriters, for whom Pennsylvania
Merchant Group Ltd and Unterberg Harris are acting as representatives (the
"Representatives"), that the Underwriters propose initially to offer the shares
of Common Stock directly to the public at the Offering Price set forth on the
cover page of this Prospectus and to certain dealers (which may include
Underwriters) at such public offering price less a concession not to exceed
$    per share. The Underwriters may allow, and such dealers may reallow, a
discount not to exceed $    per share in sales to certain other dealers. After
the public offering, the public offering price and concessions and discounts
may be changed by the Representatives.
 
  Alchut has granted to the Underwriters an option, exercisable not later than
30 business days after the date of this Prospectus, to purchase up to an
additional 300,000 shares of Common Stock to cover over allotments, at the
Offering Price less the underwriting discounts and commissions set forth on the
cover page of this Prospectus. To the extent that the Underwriters exercise
such option, each of the Underwriters will have a firm commitment to purchase
approximately the same percentage thereof that the number of shares of Common
Stock to be purchased by it shown in the table above bears to the number of
shares of Common Stock offered hereby, and Alchut will be obligated pursuant to
the option to sell such shares to the Underwriters. The Underwriters may
exercise the option only for the purposes of covering over-allotments, if any,
made in connection with the distribution of the shares of Common Stock to the
public.
 
  The Representatives have informed the Company that the Underwriters do not
intend to confirm sales of shares of the Common Stock offered hereby to any
accounts over which they exercise discretionary authority.
 
  The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act.
 
  Upon the completion of this offering, Alchut and the Company's directors and
executive officers have agreed not to sell, offer to sell, contract to sell or
otherwise dispose of any of its shares of Common Stock or any other security
convertible into or exchangeable for, or options or warrants to purchase or
acquire, shares of Common Stock without the prior written consent of the
Representatives for a period of 180 days after the date
 
                                       49
<PAGE>
 
of this Prospectus. In addition, the Company has agreed not to sell, issue,
contract to sell, offer to sell or otherwise dispose of any shares of Common
Stock or any other security convertible into or exchangeable for shares of
Common Stock without the prior written consent of the Representatives during
the same period, subject to certain exceptions including the issuance and sale
of Common Stock or securities convertible into or exchangeable for Common Stock
in connection with acquisitions and of the grant of options under the Incentive
Plan. See "Shares Eligible For Future Sale."
 
  Prior to this offering, there has been no public market for the Common Stock.
The market prices to the public will be determined by negotiations between the
Company and the Representatives. The factors to be considered in determining
such public offering price will include the Company's historical and pro forma
operations, the industry in which the Company operates, the Company's
prospects, assets, earnings, financial condition and management and the market
prices for securities of companies in businesses similar to that of the
Company.
   
  The Representatives have advised the Company that, pursuant to Regulation M
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
certain persons participating in this offering may over-allot or effect
transactions which stabilize, maintain or otherwise affect the market price of
the Common Stock at levels above those which might otherwise prevail in the
open market, including entering stabilizing bids, effecting syndicate covering
transactions or imposing penalty bids. A stabilizing bid means the placing of
any bid or the effecting of any purchase for the purpose of pegging, fixing or
maintaining the price of the Common Stock. A syndicate covering transaction
means the placing of any bid on behalf of the underwriting syndicate or the
effecting of any purchase to reduce a short position created in connection with
this offering. A penalty bid means an arrangement that permits the Underwriters
to reclaim a selling concession otherwise accruing to an Underwriter or a
syndicate member in connection with this offering when shares of Common Stock
sold by such Underwriter or syndicate member are purchased in syndicate
covering transactions. Such transactions may be effected on the Nasdaq Stock
Market, in the over-the-counter market, or otherwise. Such stabilizing, if
commenced, may be discontinued at any time.     
 
  The Company has agreed to pay the Representatives a non-accountable expense
allowance of $100,000 at closing.
 
  One or more of the Underwriters have informed the Company that they currently
intend to make a market in the Common Stock subsequent to the date of this
Prospectus, but there can be no assurance that an active trading market will
develop or continue after this offering.
 
                                 LEGAL MATTERS
 
  The validity of the Common Stock offered hereby will be passed upon for the
Company by Blank Rome Comisky & McCauley, Philadelphia, Pennsylvania. Certain
legal matters will be passed upon for the Underwriters by Duane, Morris &
Heckscher, Philadelphia, Pennsylvania.

                                    GLOSSARY
 
  Anechoic chamber -- An enclosure that has been fitted with materials that
absorb electromagnetic waves. Anechoic chambers provide an interference-free
environment for microwave test and measurement systems.
 
  BIRD -- Binational Research and Development Foundation. An Israeli-American
organization that funds research and development work conducted by Israeli-
American companies. Sales of products developed with BIRD funds are, under
certain circumstances, subject to royalties.
 
  Chief Scientist Program -- A program sponsored by the Israeli government in
which export-oriented Israeli companies can apply for research and development
grants.
 
  Compact range -- A compact range relies on a highly accurate machined
parabolic reflector to create a planar radiated electromagnetic wave. A
spherical wave radiating from the transmit antenna strikes the parabola and is
reflected as a planar wave toward the receive antenna. Since the receive
antenna sees a planar wave, the collected data can be analyzed using standard
far-field methods. A compact range system offers a primary benefit of far-field
testing (i.e. no complex mathematical transformations) as well as one of the
main benefits of near-field testing (i.e. indoor range). Compact range systems
are generally more expensive than standard far-field or near-field systems.
 
  Far-Field -- A microwave measurement is said to be conducted in the far-field
when the distance between the transmitting antenna and the receiving antenna is
large enough that planar electromagnetic waves reach the receiving antenna. In
other words, the distance between the two antennas is far enough that the
transmitting antenna's spherical radiation has become practically planar. Under
certain conditions far-field measurements can be taken in an indoor test
chamber (e.g. electrically small antenna and/or low frequencies). However, the
more versatile far-field facilities use large outdoor test ranges. A majority
of the Company's far-field test and measurement systems are used on outdoor
test ranges.
 
  Frequency -- The number of waves transmitted each second.
 
  GPS -- Global Positioning System. A digital geographic positioning system
incorporating a network of geo-stationary satellites and mobile earth-based
receivers. GPS technology is being used for land, air and sea-based direction-
finding and locator systems.
 
  Microwave -- Electromagnetic waves with frequencies ranging from 3 GHz to 30
GHz. For simplicity, the Company has used the word "microwave" in this
Prospectus to describe waves throughout the radio frequency (RF) spectrum.
 
  Near-Field -- A measurement is said to be conducted in the near-field when
the receiving antenna is within close proximity to the transmitting antenna
such that the measured electromagnetic waves retain their spherical
characteristics. Using proven, stable algorithms, near-field software
mathematically translates measured near-field data into data which is
equivalent to that which would be collected on a larger far-field range.
Because near-field data can be collected with only a very short distance
between the transmit and receive antennas, near-field systems can always be
installed in indoor test chambers. This is a significant benefit given that
indoor chambers provide a "cleaner" electromagnetic and meteorological test
environment. Near-field systems can also incorporate diagnostic tools for use
on certain complex microwave products such as satellite antennas, a feature
that far-field systems do not offer.
 
  PCS -- Personal Communication Systems. Digital wireless ground-based personal
voice and data communication services.
 
  Radome -- A radome is a dome-shaped casing that is placed on the leading edge
of an aircraft or missile to protect the radar and direction-finding equipment.
A radome is typically manufactured using fiberglass or other
 
                                       52
<PAGE>
 
materials that are transparent to microwave signals. Testing is performed
periodically to ensure that microwave signals are not deflected as they pass
through the radome.
 
  RCS -- Radar Cross Section. The radar "signature" of an aircraft or missile.
RCS measurement techniques record and analyze the electromagnetic reflectivity
of an aircraft or missile (or a scale model thereof), and then quantify and
qualify that object's RCS.
 
  RPC -- Radial Power Combiner. A solid-state device that adds several
identical low-energy signals together to make a single high-energy signal. RPCs
have many uses, but their most common application is in microwave transmitters.
 
  SBIR -- Small Business Innovative Research. A program sponsored by the United
States government under which companies with fewer than 500 employees can
obtain project-specific research and development grants.
 
  Shielded enclosure -- A room or chamber designed to prevent the entry or
escape of electromagnetic energy.

                        REPORT OF INDEPENDENT AUDITORS
 
Stockholder and Board of Directors
ORBIT/FR, Inc.
 
  We have audited the accompanying consolidated balance sheets of ORBIT/FR,
Inc. as of December 31, 1995 and 1996, and the related consolidated statements
of operations, stockholder's equity, and cash flows for each of the three
years in the period ended December 31, 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 consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of ORBIT/FR, Inc. at December 31, 1995 and 1996, and the consolidated results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1996, in conformity with generally accepted accounting
principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1996
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Ownership and Basis of Presentation
   
  ORBIT/FR, Inc. (the "Company"), incorporated in Delaware on December 9,
1996, is a wholly-owned subsidiary of Orbit-Alchut Technologies, Ltd., an
Israeli publicly traded corporation (hereinafter referred to as the Parent).
The Company develops, markets and supports sophisticated automated microwave
test and measurement systems for wireless communications, satellite,
automotive and aerospace/defense industries. The Company also is a distributor
of certain systems, which are manufactured by the Parent which has provided
the Company with all of its commission revenues. During the first half of
1997, the Company will phase out its sales arrangement with the Parent for the
distribution of such systems. The Company sells its products to customers
throughout Asia, Europe, Israel and North and South America (Note 8).     
 
  On December 31, 1996, as part of a corporate restructuring and in exchange
for 4,000,000 shares of the Company, the Parent transferred or caused to be
transferred to the Company, all of its issued and outstanding shares of two of
its subsidiaries, Orbit Advanced Technologies, Inc. ("Technologies"), a
Delaware corporation established in 1985, and Orbit F.R. Engineering, Ltd.
("Engineering"), an Israeli company incorporated on December 29, 1996. Both of
these subsidiaries are responsible for the microwave test and measurement
business. Prior to its incorporation on December 29, 1996, Engineering
operated as a separate division of the Parent (see Related Party Transactions
in Note 5). Effective January 1, 1997, the personnel formerly employed in the
microwave test and measurement division of the Parent are employed by
Engineering.
 
  The consolidated results of the Company reflect Technologies and Engineering
on an as-if pooled basis for businesses under common control for all periods
presented. Further, the recapitalization of these businesses on December 31,
1996 has retroactively been restated for common stock for all periods
presented.
 
Principles of Consolidation
 
  The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries (Note 13). All significant intercompany
accounts and transactions have been eliminated in consolidation.
   
Interim Financial Information     
   
  The consolidated financial statements and disclosures included herein for
the three months ended March 31, 1996 and 1997 are unaudited. These financial
statements and disclosures have been prepared by the Company in accordance
with generally accepted accounting principles and include all adjustments,
consisting of adjustments of a normal and recurring nature, which in the
opinion of management, are necessary for a fair presentation of the Company's
financial position and the results of its operations and cash flows for these
periods.     
 
Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
Inventory
 
  Inventory is stated at the lower of cost (first-in, first-out method) or
market.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
   
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)     
 
Property and Equipment
 
  Property and equipment are recorded at cost. Depreciation is computed on
accelerated methods for both financial reporting and income tax purposes over
the estimated useful lives as follows: office equipment -- 5-7 years; lab
equipment -- 5 years; furniture and fixtures -- 7 years; transportation
equipment -- 5 years; leasehold improvements -- 5 years.
 
Purchased Software
 
  Purchased software was acquired in connection with the acquisition described
in Note 13 and is being amortized on a straight-line basis over five years.
 
Revenue and Cost Recognition
 
  The Company's principal sources of contract revenues are from engineering
and design services and the production of electro-mechanical equipment.
Revenues from long-term fixed-price development contracts performed
principally under the Company's control are recognized on the percentage-of-
completion method, measured by the percentage of costs incurred to date to
estimated total costs for each contract when such costs can be reasonably
estimated. Contract costs include all direct material, labor and subcontractor
costs and those indirect costs related to contract performance such as
indirect labor, supplies and tool costs. General and administrative costs are
charged to expense as incurred. Changes in job performance, job conditions,
and estimated profitability, including those arising from contract penalty
provisions and final contract settlements may result in revisions to costs and
revenue and are recognized in the period in which the revisions are
determined. Revenues from electro-mechanical equipment sold to customers which
are not part of a larger contract are recognized when the contract is
substantially completed. Revenues recognized in excess of amounts billed are
classified under current assets as costs and estimated earnings in excess of
billings on uncompleted contracts. Amounts received from clients in excess of
revenues recognized to date are classified under current liabilities as
billings in excess of costs and estimated earnings on uncompleted contracts.
 
Research and Development
   
  Internally funded research and development costs are charged to operations
as incurred. Included in cost of revenues is customer funded research and
development costs of approximately $472,000, $482,000 and $520,000 for the
years ended December 31, 1994, 1995, and 1996, respectively, and $20,000 and
$127,000 for the three months ended March 31, 1996 and 1997, respectively.
    
Concentrations of Credit Risk
   
  Financial instruments, which potentially subject the Company to a
concentration of credit risk, consist principally of accounts receivable and
cash. To reduce credit risk relating to the Company's sales in the U.S. and
overseas, the Company performs ongoing credit evaluations of its commercial
customers' financial condition, but generally does not require collateral for
government and domestic commercial customers. For its foreign commercial
customers, the Company generally requires irrevocable letters of credit in the
amount of the total contract. At December 31, 1996 and March 31, 1997,
irrevocable letters of credit were posted for three and six of the Company's
foreign customers, respectively.     
 
Warranty Expense
 
  The Company provides for warranty costs on sales of its own product. Product
warranty periods vary, but generally extend for one year from the date of
sale.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
   
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)     
 
Income Taxes
 
  The Company uses the liability method to account for income taxes.
Accordingly, deferred income taxes reflect the net tax effect of temporary
differences between the carrying amount of assets and liabilities for
financial reporting purposes and the amounts reportable for income tax
purposes. The Company files a consolidated federal income tax return with its
domestic subsidiaries.
 
Foreign Currency Translation
   
  The Company's foreign operations' functional currency is the U.S. dollar.
Foreign currency transaction gains and losses, which are not material, are
recognized currently in the consolidated statements of operations. For the
year ended December 31, 1996 and for the three months ended March 31, 1997,
approximately 8% and 3%, respectively, of the Company's revenues were billed
in currencies other than the U.S. dollar. Substantially all of the costs of
the Company's contracts, including costs subcontracted to the Parent, have
been U.S. dollar denominated transactions, except for wages of Engineering
which are denominated in local currency.     
 
Net Income Per Share
 
  Net income per share is computed using the weighted average number of common
shares outstanding during the period. The common shares outstanding for all
periods have been restated to reflect the corporate restructuring described in
Note 1.
   
  In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings Per Share," which is required to be adopted on December 31,
1997. Under the new requirements for calculating primary earnings per share,
the dilutive effect of stock options will be excluded. The impact of Statement
No. 128 on the calculation of the Company's primary and fully diluted earnings
per share is not expected to be material.     
 
Long-Lived Assets
 
  During the year ended December 31, 1996, the Company adopted Financial
Accounting Standards Board (FASB) Statement No. 121 (SFAS 121), "Accounting
for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be
Disposed of." SFAS 121 did not have an impact on the Company's financial
condition or results of operations.
 
Accounting for Stock Options
   
  During the year ended December 31, 1996, the Company adopted the Financial
Accounting Standards Board Statement No. 123 (SFAS 123), "Accounting for Stock
Based Compensation." SFAS 123 provides companies with a choice to follow the
provision of SFAS 123 in the determination of stock-based compensation
expenses or to continue with the provisions of APB 25, "Accounting for Stock
Issued to Employees." The Company will continue to follow APB 25 and will
provide pro forma disclosures as required by SFAS 123. SFAS 123 did not have
an impact on the Company's financial condition or results of operations.     
   
Fair Value of Financial Instruments     
   
  Financial Accounting Standards Board Statement No. 107, Disclosures About
Fair Value of Financial Instruments, defines the fair value of a financial
instrument as the amount at which the instrument could be exchanged in a
current transaction between willing parties. Cash, accounts receivable, other
current assets, accounts payable and accrued expenses reported in the
consolidated balance sheets equal or approximate fair value due to their short
maturities. Based on the borrowing rates currently available to the Company,
the fair value of the Company's long-term debt is approximately $3 million.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
 
5. RELATED PARTY TRANSACTIONS
   
  The financial results of Engineering include all contract revenue of the
microwave test and measurement business unit of the Parent, direct contract
costs, direct personnel costs, electrical and mechanical production services in
an amount equal to the Parent's cost of providing such services plus 5% and pro
rata allocations of administrative expenses from the Parent to Engineering.
Such allocations of administrative expenses are based on management's estimate
of the level of these expenses required to support Engineering, relative to the
reasonable allocation of such costs. Interest expense on intercompany debt has
not been provided. The average balance of the intercompany debt for the three
years ended December 31, 1996 was approximately $3.0 million. Income taxes for
Engineering are in accordance with the statutory rates in Israel net of
adjustments allowable under local law. The "Parent's Equity in Division" of
Engineering has been reflected as a contribution of additional paid-in capital
upon its incorporation on December 29, 1996.     
 
  Note payable -- Parent reflects the amount due to the Parent for the net
working capital required by Engineering. At December 31, 1996, the balance of
$2,722,000 was converted into a three year, non-interest bearing promissory
note payable due in 1999.
   
  Included in cost of revenues for the years ended December 31, 1994, 1995,
1996 and for the three months ended March 31, 1996 and 1997, are approximately
$1,492,000, $1,423,000, $1,496,000, and $298,000 and $323,000, respectively,
relating to the production services provided by the Parent. Commission revenue
results from amounts earned as a distributor of certain systems manufactured by
the Parent. Accounts payable -- Parent reflects the balance outstanding
relating to these transactions with the Parent.     
 
  Effective January 1, 1997, Engineering and the Parent entered into an
agreement, whereby Engineering will purchase from the Parent electrical and
mechanical production services. Engineering will pay the Parent the cost of
providing such services plus 5%. The Parent will provide other administrative
services, including but not limited to, bookkeeping, computer, legal,
accounting, cost management, information systems, and production support for a
fixed amount of $360,000 during 1997. This amount will be evaluated and
determined on an annual basis. Engineering is leasing office space from the
Parent on an annual basis, for a rental of $51,000 per year.
 
6. LINE OF CREDIT AGREEMENTS
   
  The Company has a $1,000,000 line of credit with a bank of which no amounts
were outstanding at December 31, 1995 and 1996, respectively. The line is
renewable annually in April and bears interest at .5% over the banks prime rate
(8.75% at December 31, 1996). The line is secured by accounts receivable and
requires a compensating cash balance of 50% of the outstanding amount of the
line. At December 31, 1996, $500,000 was not available to the Company as it was
being held for a letter of credit. During May 1997, the $500,000 letter of
credit was terminated in connection with the final payment of the Flam &
Russell purchase price (Note 13).     
 
  The Company also has a $150,000 line of credit with a bank of which the
entire amount is available at December 31, 1996. The line is renewable annually
in April and bears interest at 1.5% over the bank's prime rate (9.75% at
December 31, 1996). The line is secured by accounts receivable.
   
  The terms of these line of credit agreements have been extended by the bank
through July 31, 1997.     
 
7. COMMITMENTS
   
  The Company leases its operating facilities and certain equipment under
noncancelable operating lease agreements which expire in various years through
1999. Rent expense for the years ended December 31, 1994, 1995, and 1996 was
approximately $43,000, $48,000, and $120,000, respectively and for the three
months ended March 31, 1996 and 1997 was approximately $10,500 and $55,000
respectively. Future minimum payments under noncancelable operating leases with
initial terms of one year or more is as follows at December 31, 1996: $179,000
in 1997; $45,000 in 1998; $9,500 in 1999 and $2,500 in 2000. Subsequent to
December 31, 1996 the Company entered into a sublease agreement for one of its
operating facilities. Future minimum rentals to be received under this sublease
are as follows: $37,000 in 1997; $44,000 in 1998 and $7,400 in 1999.

  Deferred tax assets at December 31, 1996 arise from net operating losses of
approximately $395,000 and tax credits of approximately $142,000 which the
Company acquired in its acquisition of Flam & Russell, Inc. (Note 13). The tax
benefit of these losses and credits may be limited both in time and amount due
to limitations imposed by Section 382 of the Internal Revenue Code. Net
operating loss and credit carryforwards expire during various dates from 1999
through 2011.     
 
  The components of income tax (benefit) expense are as follows:

14. STOCKHOLDER'S EQUITY
 
Common Stock
 
  The holders of shares of Common Stock are entitled to one vote for each share
on record on any matters to be voted on by the stockholder. The holders of
Common Stock are entitled to receive dividends if declared by the Board of
Directors and to share ratably in the assets of the Company legally available
for distribution to its stockholders in the event of liquidation, dissolution
or winding-up of the Company. Holders of Common Stock have no preemptive,
subscription, redemption or conversion rights.
 
Preferred Stock
 
  The Company's Board of Directors may, without further action by the Company's
stockholder, from time to time, direct the issuance of shares of Preferred
Stock in series and may, at the time of issuance, determine the rights,
preferences and limitations of each series. The holders of Preferred Stock
would normally be entitled to receive a preference payment in the event of any
liquidation, dissolution or winding-up of the Company before any payment is
made to the holders of the Common Stock. The issuance of Preferred Stock could
decrease the amount of earnings and assets available for distribution to the
holders of Common Stock or could adversely affect the rights and powers,
including voting rights, of the holders of Common Stock.
 
Stock Option Plan
   
  During March 1997, the Board of Directors adopted, and the Company's
Stockholder approved, the Company's 1997 Equity Incentive Plan (the "Incentive
Plan"). The purposes of the Incentive Plan is to promote the long-term
retention of the Company's key employees and certain other persons who are in a
position to make significant contributions to the success of the Company. The
Incentive Plan permits grants of incentive stock options ("ISOs"), options not
intended to qualify as ISOs ("nonqualified options"), stock appreciation rights
("SARs"), restricted, unrestricted and deferred stock awards, performance
awards, loans and supplemental cash awards, and combinations of the foregoing
(all referred to as "Awards").     
 
  The Incentive Plan provides for awards of 800,000 shares of the Company's
Common Stock of which 492,300 shares will be granted at the initial public
offering price and will vest over four years. Future shares will be granted at
the fair market value on the date of grant and will vest over four years.
 
15. EVENTS "UNAUDITED" SUBSEQUENT TO THE DATE OF THE REPORT OF INDEPENDENT
AUDITORS
 
  In April 1997, the Board of Directors of the Company authorized the filing of
a Registration Statement with the Securities and Exchange Commission for the
offer and sale of up to 2,000,000 shares of its Common Stock.
   
  On March 31, 1997, the Company entered into an agreement with Advanced
Electromagnetics, Inc., a California corporation ("AEMI"), pursuant to which
all of the issued and outstanding shares of AEMI will be sold to the Company,
contemporaneously with the completion of this offering, for up to a maximum of
$1.6 million, subject to adjustment based on AEMI's financial performance for
the three years ended March 31, 1997. One-half of the purchase price will be
paid in cash and the other half will be paid by issuance of shares of the
Company's Common Stock valued at the Offering Price.

To the Stockholders
Flam & Russell, Inc.
Horsham Pennsylvania
 
  We have audited the accompanying balance sheets of Flam & Russell, Inc. (a
wholly-owned subsidiary of Orbit Advanced Technologies, Inc.) as of June 30,
1995 and June 28, 1996 and the related statements of income, changes in
stockholders' equity and cash flows for each of the three fiscal years in the
period ended June 28, 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 financial position of Flam & Russell, Inc. as of
June 30, 1995 and June 28, 1996 and the results of its operations and its cash
flows for each of the three fiscal years in the period ended June 28, 1996 in

                         NOTES TO FINANCIAL STATEMENTS
 
                 JULY 1, 1994, JUNE 30, 1995 AND JUNE 28, 1996
 
NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  This summary of significant accounting policies of Flam and Russell, Inc.
(the Company) is presented to assist in the understanding of the financial
statements.
 
Organization and Nature of Operations
 
  The Company was incorporated in the State of Delaware on July 8, 1980 and
became a wholly owned subsidiary of Orbit Advanced Technologies, Inc. on June
28, 1996. It is an engineering firm specializing in research, development, and
design services in the areas of microwave, antenna, and related technology.
The Company markets its product and services worldwide.
 
Use of Estimate
 
  Management uses estimates and assumptions in preparing financial statements.
Those estimates and assumptions affect the reported amounts of assets and
liabilities, the disclosure of contingent assets and liabilities, and the
reported revenues and expenses. Actual results could differ from those
estimates.
 
Inventories
 
  Inventories are valued at the lower of cost or market. Cost is determined by
the average cost method.
 
Property and Equipment
 
  Property and equipment are stated at cost. Depreciation is provided using
straight-line and accelerated methods over the estimated useful lives of the
assets.
 
Revenue Recognition
 
  The Company accounts for certain contracts on the percentage-of-completion
method in which income is recognized in the ratio that costs incurred bears to
estimated total costs. Adjustments to cost estimates are made periodically,
and losses expected to be incurred on contracts in progress are charged to
operations in the period such losses are determined. The aggregate of costs
incurred and income recognized on uncompleted contracts in excess of related
billings is shown as a current asset, and the aggregate of billings on
uncompleted contracts in excess of related costs incurred and income
recognized is shown as a current liability.
 
Deferred Income Taxes
 
  Deferred taxes reflect the net tax effects of temporary differences between
the carrying amounts of assets and liabilities for financial reporting
purposes and amounts used for income tax purposes. These differences related
principally to the Company recognizing revenue on the percentage of completion
method for financial reporting purposes and the completed contract method for
income tax purposes. Deferred taxes are also recognized for operating losses
that are available to offset future taxable income and tax credits that are
available to offset future federal income taxes.
 
NOTE B -- CREDIT RISK
 
  The Company maintains cash deposits, at primarily one financial institution
that may at times exceed the $100,000 federally insured limits. At June 28,
1996, the Company has uninsured cash deposits of $119,042.

Inc. certain stockholders of the Company were beneficiaries of the Trust.
 
  On June 30, 1995, the trustees of the Trust agreed to waive and forgo the
payments of accrued interest through that date. This transaction resulted in
an extrordinary gain of $400,902.
 
  On June 28, 1996, with the approval of the Board of Directors, the
outstanding balance of the notes payable to the Trust of $850,000, and accrued
interest of $63,042 was converted to 3,300 shares of Class A common stock and
37,500 shares of Class B common stock of the Company, in the amount of
$510,000, and the remainder was recorded as an extraordinary gain of $403,042.
The Company valued each share issued at $12.50, which was equivalent to the
amount received by the Company's shareholders in connection with the sale of
their shares on June 28, 1996.

NOTE N -- CONTINGENT LIABILITY
 
  The State of California is currently examining the Company's liability for
back sales tax and has proposed certain adjustments that aggregate
approximately $28,000 of additional sales tax. The Company does not agree with
the basis upon which the adjustments are calculated. The ultimate resolution
is not presently determinable.
 
NOTE O -- SALE OF BUSINESS
 
  On June 28, 1996, the Company's stockholders sold all their shares of the
Company to Orbit Advanced Technologies, Inc.
 
NOTE P -- ADJUSTMENTS TO FINANCIAL STATEMENTS ISSUED PREVIOUSLY
 
  At the time that the original financial statements were issued for the
period ended June 28, 1996, management had determined that the extraordinary
gain, as more fully described in Note K, should be presented net of applicable
taxes. The current facts no longer support this position, as management has
determined that this gain is a permanent difference for tax purposes. The
financial statements for this period have been adjusted as follows:

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
  The DGCL provides, in substance, that Delaware corporations shall have the
power, under specified circumstances, to indemnify their directors, officers,
employees and agents in connection with actions, suits or proceedings brought
against them by third parties and in connection with actions or suits by or in
the right of the corporation, by reason of the fact that they were or are such
directors, officers, employees and agents, against expenses (including
attorneys' fees) and, in the case of actions, suits or proceedings brought by
third parties, against judgments, fines and amounts paid in settlement
actually and reasonably incurred in any such action, suit or proceeding.
 
  The Company's Bylaws also provide for indemnification to the fullest extent
permitted by the Delaware General Corporation Law. Reference is made to the
Bylaws of the Company.
 
  As permitted by the DGCL, the Company's Certificate of Incorporation
eliminates the personal liability of its directors to the Company and its
stockholders, in certain circumstances, for monetary damages arising from a
breach of the director's duty of care.
 
  The Company intends to obtain directors' and officers' liability insurance
which covers certain liabilities, including liabilities to the Company and its
stockholders, in the amount of $5.0 million.
 
  The Underwriting Agreement to be filed as Exhibit 1.1 to this Registration
Statement provides for indemnification by the Underwriters of certain
officers, directors and controlling persons of the Company with respect to
certain liabilities in connection with this offering.
 
ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.
 
  During the past three years, the Company has issued unregistered securities
to a limited number of persons, as described below. No underwriters or
underwriting discounts or commissions were involved. There was no public
offering in any such transaction, and the Company believes that each
transaction was exempt from registration requirements of the Securities Act,
by reason of Section 4(2) thereof. Pursuant to the Share Exchange Agreement
dated December 31, 1996 by and among the Company, Alchut and Orbit Advanced
Systems, Ltd.,
 
                                     II-1
<PAGE>
 
the Company issued 3,999,520 shares of common stock to Alchut in consideration
for 10 shares of the common stock of Technologies and 99 shares of the
ordinary stock of Engineering and issued 480 shares of common stock to Orbit
Advanced Systems, Ltd. in exchange for 1 share of the ordinary stock of
Engineering.

  shall be deemed to be a new Registration Statement relating to the
  securities offered therein, and this offering of such securities at that
  time shall be deemed the initial bona fide offering thereof.
 
  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 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 of 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.
 
  The undersigned registrant hereby undertakes to provide to the underwriter
at the closing specified in the underwriting agreements certificates in such
denominations and registered in such names as required by the underwriter to
permit prompt delivery to each purchaser.

Pennsylvania Merchant Group Ltd
Unterberg Harris
   As Representatives of the Several
   Underwriters Named in Schedule I
   Attached Hereto
Four Falls Corporate Center
West Conshohocken, Pennsylvania 19428

Dear Sirs:

     Orbit/FR, Inc., a Delaware corporation (the "Company"), proposes to issue
and sell an aggregate of 2,000,000 shares of its common stock to Pennsylvania
Merchant Group Ltd and Unterberg Harris (the "Representatives") and the several
underwriters named in Schedule I hereto (collectively with the Representatives,
the "Underwriters" and individually, an "Underwriter," which terms shall also
include any Underwriter substituted as hereinafter provided in Section 11). The
shares of the Company's common stock, par value $.01 per share, are hereinafter
referred to as the "Common Shares," and the 2,000,000 Common Shares to be issued
and sold to the Underwriters by the Company are hereinafter referred to as the
"Offered Shares." The initial public offering price per Offered Share (the
"Offering Price") and the purchase price per Offered Share for the Offered
Shares to be paid by the several Underwriters shall be agreed upon by the
Company, the Selling Stockholder and the Representatives, acting on behalf of
the several Underwriters, and such agreement shall be set forth in a separate
written instrument substantially in the form of Exhibit A hereto (the "Price
Determination Agreement"). The Price Determination Agreement may take the form
of an exchange of any standard form of written telecommunication among the
Company, the Selling Stockholder and the Representatives and shall specify such
applicable information as is indicated in Exhibit A hereto. The offering of the
Shares will be governed by this Agreement, as supplemented by the Price
Determination Agreement. From and after the date
<PAGE>
 
of execution and delivery of the Price Determination Agreement, this Agreement
shall be deemed to incorporate, and, unless the context otherwise indicates, all
references contained herein to "this Agreement" and to the phrases "herein" and
"hereof" shall be deemed to include the Price Determination Agreement.

     In addition, the Underwriters, in order to cover over-allotments in the
sale of the Offered Shares, may purchase from Orbit-Alchut Technologies, Ltd.,
an Israeli corporation (the "Selling Stockholder") within 30 business days
after the Effective Date (as hereinafter defined), for their own account for
offering to the public at the Offering Price, up to 300,000 additional Common
Shares (the "Optional Shares"), upon the terms and conditions set forth in
Section 4 hereof. The Selling Stockholder has executed and delivered a Power of
Attorney and a Custody Agreement in the form attached hereto as Exhibit B
(collectively, the "Agreement and Power of Attorney") pursuant to which the
Selling Stockholder has placed the Optional Shares in custody and appointed the
person or persons designated therein with authority to execute and deliver this
Agreement on behalf of the Selling Stockholder and to take certain other actions
with respect thereto and hereto. The Offered Shares and the Optional Shares are
hereinafter collectively referred to as the "Shares." The Company and the
Selling Stockholder, intending to be legally bound hereby, confirm their
respective agreements with each of the Underwriters as follows:

     1.   Representations and Warranties.

          (a)   The Company represents and warrants to, and agrees with, the
     several Underwriters that:

                (i)   The Company has prepared in conformity with the
          requirements of the Securities Act of 1933, as amended (the "Act"),
          and the rules, regulations, releases and instructions (the
          "Regulations") of the Securities and Exchange Commission (the "SEC")
          under the Act in effect at all applicable times and has filed with the
          SEC a registration statement on Form S-1 (File No. 333-25015) and one
          or more amendments thereto registering the Shares under the Act. If
          the Company elects to rely on Rule 462(b) of the Regulations to
          register a portion of the Shares, a registration statement on Form S-1
          relating to the Shares (the "Rule 462 registration statement") has
          been or will be prepared by the Company under the Act and the
          Regulations and has been or will be filed with the SEC. Any
          preliminary prospectus included in such registration statement or
          filed with the SEC pursuant to Rule 424(a) of the Regulations is
          hereinafter called a "Preliminary Prospectus." The various parts of
          such initial registration statement, including all exhibits thereto
          and the information contained in the form of final prospectus filed
          with the SEC pursuant to Rule 424(b) of the Regulations in accordance
          with Section 5(a) of this Agreement and deemed by virtue of Rule 430A
          of the Regulations to be part of the registration statement at the
          time it was declared effective, each as amended at the time

                                      -2-
<PAGE>
 
          the registration statement became effective, and any Rule 462
          registration statement at the time it becomes or became effective, are
          hereinafter collectively called the "Registration Statement." The
          final prospectus in the form included in the Registration Statement
          and any Rule 462 registration statement or first filed with the SEC
          pursuant to Rule 424(b) of the Regulations and any amendments or
          supplements thereto is hereinafter collectively called the
          "Prospectus."

               (ii)   The Registration Statement and any Rule 462 registration
          statement have become effective under the Act as of their respective
          Effective Date (as defined below), and the SEC has not issued any stop
          order suspending the effectiveness of such Registration Statement or
          Rule 462 registration statement or preventing or suspending the use of
          the Preliminary Prospectus nor, to the knowledge of the Company, has
          the SEC instituted, contemplated or threatened to institute
          proceedings with respect to such an order. No stop order suspending
          the sale of the Shares in any jurisdiction designated by the
          Representatives pursuant to Section 5(f) hereof has been issued, and
          no proceedings for that purpose, to the knowledge of the Company, have
          been instituted or are contemplated or threatened. The Company has
          complied in all material respects with any request of the SEC, or any
          state securities commission in a state designated by the
          Representatives pursuant to Section 5(f) hereof, for additional
          information to be included in the Registration Statement or Prospectus
          or otherwise. Each Preliminary Prospectus conformed to the Act and the
          Regulations as of its date in all material respects and did not as of
          its date contain any untrue statement of a material fact or omit to
          state a material fact required to be stated therein or necessary to
          make the statements therein, in light of the circumstances under which
          they were made, not misleading, except the foregoing shall not apply
          to statements in or omissions from any Preliminary Prospectus in
          reliance upon and in conformity with information furnished to the
          Company in writing by or on behalf of any Underwriter through the
          Representatives expressly for use therein. The Registration Statement
          and any Rule 462 registration statement on the date on which it is
          declared effective by the SEC (the "Effective Date") conformed, and
          any post-effective amendment thereof on the date it shall become
          effective, and the Prospectus at the time it is filed with the SEC
          pursuant to Rule 424(b) and on the Closing Date (as defined in Section
          3 hereof) and any Option Closing Date (as defined in Section 4(b)
          hereof), will conform in all material respects to the requirements of
          the Act and the Regulations, and neither the Registration Statement,
          any Rule 462 registration statement, any post-effective amendment
          thereof nor the Prospectus will, on any of such respective dates,
          contain any untrue statement of a material fact or omit to state any
          material fact required to be stated therein or necessary to make the

                                      -3-
<PAGE>
 
          statements therein not misleading, except that this representation and
          warranty does not apply to statements in or omissions from the
          Registration Statement, any Rule 462 registration statement or the
          Prospectus made in reliance upon and in conformity with information
          furnished to the Company in writing by or on behalf of any Underwriter
          through the Representatives expressly for use therein.

              (iii)   Each of the Company and the Subsidiaries (as defined
          herein) is a corporation duly organized, validly existing and in good
          standing under the laws of its jurisdiction of incorporation with all
          necessary power and authority, corporate and other, and all required
          licenses, permits, certifications, registrations, approvals, consents
          and franchises, to own or lease and operate its properties and to
          conduct its business as described in the Prospectus. The Company has
          full power and authority, corporate and other, to execute, deliver and
          perform this Agreement. Each of the Company and the Subsidiaries is
          duly qualified to do business as a foreign corporation and is in good
          standing in all jurisdictions in which such qualification is required,
          except where the failure so to qualify would not have a material
          adverse effect on the general affairs, properties, condition
          (financial or otherwise), results of operations, stockholders' equity,
          business or prospects of the Company and the Subsidiaries. The Company
          does not own any stock or other equity interest in any corporation,
          partnership, joint venture or other entity other than Orbit Advanced
          Technologies, Inc., a Delaware corporation and its wholly owned
          subsidiary, Flam & Russell, Inc., a Delaware corporation ("Flam &
          Russell") and Orbit F. R. Engineering, Ltd., an Israeli corporation
          (collectively, the "Subsidiaries"). For the purposes of this
          Agreement, the term "Subsidiary") shall also include Advanced
          Electromagnetics, Inc. ("AEMI"), a California corporation. No
          Subsidiary is currently prohibited, directly or indirectly, from
          paying any dividends to the Company, from making other distributions
          on such Subsidiary's capital stock, from repaying to the Company any
          loans or advances to such Subsidiary or from transferring any of such
          Subsidiary's property or assets to the Company or any other
          Subsidiary, except as disclosed in the Prospectus. All material
          transactions between the Company and the Subsidiaries and the
          officers, directors and stockholder of the Company have been
          accurately disclosed in the Registration Statement and the terms of
          each such transaction are fair to the Company and no less favorable to
          the Company than the terms that could have been obtained from
          unrelated parties.

               (iv)   All of the issued shares of capital stock of each of the
          Subsidiaries have been duly authorized and validly issued, are fully
          paid and nonassessable and are owned beneficially, or will be owned
          beneficially in the case of AEMI upon the Closing Date, by the Company
          free and clear of all liens, security interests, pledges, charges,
          encum-

                                      -4-
<PAGE>
 
          brances, defects, stockholders' agreements, voting trusts, equities or
          claims of any nature whatsoever.

                (v)   This Agreement has been duly authorized, executed and
          delivered by the Company and, assuming due execution by the
          Representatives, constitutes the legal, valid and binding obligation
          of the Company, enforceable against the Company in accordance with its
          terms, subject, as to enforcement, to applicable bankruptcy,
          insolvency and moratorium laws and other laws relating to or affecting
          the enforcement of creditors' rights generally and to general
          equitable principles and except as the enforceability of rights to
          indemnity and contribution hereunder may be limited by federal or
          state securities laws or principles of public policy underlying such
          laws.

               (vi)   The issue and sale of the Shares to be issued and sold by
          the Company and the execution, delivery and performance of this
          Agreement by the Company does not and will not, with or without the
          giving of notice or the lapse of time, or both, (A) conflict with any
          terms or provisions of the Certificate of Incorporation or By-laws, as
          amended to the date hereof of the Company or any of the Subsidiaries;
          (B) result in a breach of, constitute a default under, result in the
          termination or modification of or result in the creation or imposition
          of any lien, security interest, charge or encumbrance upon any of the
          properties of the Company or any of the Subsidiaries pursuant to, any
          indenture, mortgage, deed of trust, contract, commitment or other
          agreement or instrument to which the Company or any of the
          Subsidiaries is a party or by which any of the properties of the
          Company or any of the Subsidiaries are bound or affected; (C) violate
          any law, rule, regulation, judgment, order or decree of any government
          or governmental agency, instrumentality or court, domestic or foreign,
          having jurisdiction over the Company or any of the Subsidiaries or any
          of the properties or business of the Company or any of the
          Subsidiaries or (D) result in a breach, termination or lapse of the
          power and authority of the Company or any of the Subsidiaries to own
          or lease and operate its properties and conduct its business as
          described in the Prospectus.

              (vii)   At the date or dates indicated in the Prospectus, the
          Company had the capitalization set forth under the caption
          "Capitalization" in the Prospectus and will have the pro forma
          capitalization and the pro forma as adjusted capitalization set forth
          under the caption "Capitalization" in the Prospectus. On the Effective
          Date, the Closing Date and any Option Closing Date, there will be no
          options or warrants for the purchase of, other outstanding rights to
          purchase, agreements or obligations to issue or agreements or other
          rights to convert or exchange any obligation or security into, capital
          stock of the Company or any of the Subsidiaries or securities
          convertible into or exchangeable

                                      -5-
<PAGE>
 
          for capital stock of the Company or any such Subsidiary, except as
          described in the Registration Statement or the Prospectus with respect
          to the (A) outstanding options that have been granted to employees and
          directors to purchase 492,300 Common Shares (the "Employee Options")
          and (B) the Over-allotment Option granted hereunder.

             (viii)   The authorized capital stock of the Company, including,
          without limitation, the outstanding Common Shares and the Shares being
          issued on the Closing Date and any Option Closing Date, conforms in
          all material respects with the descriptions thereof in the Prospectus,
          and such descriptions conform in all material respects with the
          descriptions thereof set forth in the instruments defining the same.
          The information in the Prospectus insofar as it relates to the
          Employee Options as of the Effective Date and immediately prior to the
          Closing Date is true and correct in all material respects.

               (ix)   The outstanding Common Shares have been duly authorized
          and are validly issued, fully paid and non-assessable and the Employee
          Options have been duly authorized and validly issued and are legal,
          valid and binding obligations enforceable against the Company in
          accordance with the terms thereof. The Common Shares issuable pursuant
          to the Employee Options, when issued in accordance with the terms
          thereof, will be duly authorized, validly issued, fully-paid and
          nonassessable. None of such outstanding Common Shares, Employee
          Options or shares of capital stock of each Subsidiary were, and none
          of such issuable Common Shares will be, issued in violation of any
          preemptive rights of any security holder of the Company or any
          Subsidiary that have not been waived. The Company has reserved a
          sufficient number of Common Shares for issuance pursuant to the
          Employee Options. The holders of the outstanding Common Shares are not
          subject to personal liability solely by reason of being such holders,
          and the holders of the Common Shares issuable pursuant to the Employee
          Options will not be subject to personal liability solely by reason of
          being such holders. The offers and sales of the outstanding Common
          Shares, the Employee Options and the shares of capital stock of each
          Subsidiary were, and the issuance of the Common Shares pursuant to the
          Employee Options will be, made in conformity with applicable
          registration requirements or exemptions therefrom under federal and
          applicable state securities laws.

                (x)   The issuance and sale of the Shares by the Company have
          been duly authorized and, when the Shares have been duly delivered
          against payment therefor as contemplated by this Agreement, the Shares
          will be validly issued, fully paid and nonassessable, and the holders
          thereof will not be subject to personal liability solely by reason of
          being such holders. None of the Shares will be issued in violation of
          any preemptive rights of any stockholder of

                                      -6-
<PAGE>
 
          the Company. The certificates representing the Shares are in proper
          legal form under, and conform in all respects to the requirements of,
          the Delaware General Corporation law, as amended (the "DGCL"). Neither
          the filing of the Registration Statement nor the offering or sale of
          the Shares as contemplated by this Agreement gives any security holder
          of the Company any rights, other than those which have been waived,
          for or relating to the registration of any Common Shares or other
          security of the Company.

               (xi)   No consent, approval, authorization, order, registration,
          license or permit of any court, government, governmental agency,
          instrumentality or other regulatory body or official is required for
          the valid authorization, issuance, sale and delivery by the Company of
          any of the Shares, or for the execution, delivery or performance by
          the Company of this Agreement, except such as may be required for the
          registration of the Shares under the Act, the Regulations and the
          Securities Exchange Act of 1934, as amended (the "Exchange Act"),
          which consent, approval and authorization have been obtained, and for
          compliance with the applicable state securities or Blue Sky laws, or
          the By-laws, rules and other pronouncements of the National
          Association of Securities Dealers, Inc. ("NASD"). Upon the
          effectiveness of the Registration Statement, the Common Shares will be
          registered pursuant to Section 12(g) of the Exchange Act, and will be
          listed on the National Market System ("NMS") of the NASD Automated
          Quotation System ("Nasdaq"). The Company has taken no action designed
          to, or likely to, have the effect of terminating the registration of
          the Common Shares from the Nasdaq NMS, nor has the Company received
          any notification that the SEC or the NASD is contemplating terminating
          such registration or listing.

              (xii)   The statements in the Registration Statement and the
          Prospectus, insofar as they are descriptions of or references to
          statutes, legal and governmental proceedings or contracts, agreements
          or other documents, are accurate in all material respects and present
          or summarize fairly, in all material respects, the information
          required to be disclosed under the Act or the Regulations, and there
          are no contracts, agreements or other documents required to be
          described or referred to in the Registration Statement or the
          Prospectus or to be filed as exhibits to the Registration Statement
          under the Act or the Regulations that have not been so described,
          referred to or filed, as required.

             (xiii)   The consolidated financial statements of the Company and
          its consolidated subsidiaries and the financial statements of Flam &
          Russell (including the notes thereto) filed as part of the Preliminary
          Prospectus, the Prospectus and the Registration Statement present
          fairly, in all material respects, the financial position of the
          Company as of the respective dates thereof, and the results of
          operations and cash flows of the Company and its consolidated

                                      -7-
<PAGE>
 
          subsidiaries, on a consolidated basis, and of Flam & Russell,
          respectively at the dates and for the periods indicated therein, all
          in conformity with generally accepted accounting principles
          consistently applied. The supporting schedules included in the
          Registration Statement fairly state in all material respects the
          information required to be stated therein in relation to the basic
          financial statements taken as a whole. The financial information
          included in the Prospectus under the captions "Prospectus Summary" and
          "Selected Consolidated Financial Data" presents fairly the information
          shown therein and has been compiled on a basis consistent with that of
          the audited financial statements included in the Registration
          Statement. No other financial statements or schedules of any
          Subsidiary are required by the Act or the Regulations to be included
          in the Registration Statement or the Prospectus.

              (xiv)   Since the respective dates as of which information is
          given in the Registration Statement and the Prospectus, except as
          otherwise stated therein, there has not been (A) any material adverse
          change, including, whether or not insured against, any material loss
          or damage to any assets, or development involving a prospective
          material adverse change, in the general affairs, properties, assets,
          management, condition (financial or otherwise), results of operations,
          stockholders' equity, business or prospects of the Company or any of
          the Subsidiaries, (B) any transaction entered into by the Company or
          any of the Subsidiaries that is material to the Company and the
          Subsidiaries, (C) any dividend or distribution of any kind declared,
          paid or made by the Company or any of the Subsidiaries on their
          respective capital stock, (D) any liabilities or obligations, direct
          or indirect, incurred by the Company or any of the Subsidiaries that
          are material to the Company and the Subsidiaries or (E) any material
          change in the short-term debt or long-term debt of the Company or any
          of the Subsidiaries. Neither the Company nor any of the Subsidiaries
          has any contingent liabilities or obligations that are material and
          that are not disclosed in the Prospectus.

               (xv)   The Company has not distributed and, prior to the later to
          occur of the Closing Date, the Option Closing Date or the completion
          of the distribution of the Shares, will not distribute any offering
          material in connection with the offering and sale of the Shares other
          than the Registration Statement, the Preliminary Prospectus, the
          Prospectus and other materials, if any, permitted by the Act and the
          Regulations.

              (xvi)   The Company and each of the Subsidiaries has filed with
          the appropriate federal state and local governmental agencies, and all
          foreign countries and political subdivisions thereof, all material tax
          returns that are required to be filed or has duly obtained extensions
          of time for the filing thereof and has paid all taxes shown on

                                      -8-
<PAGE>
 
          such returns and all material assessments received by it to the extent
          that the same have become due. The Company and each of the
          Subsidiaries has not executed or filed with any taxing authority,
          foreign or domestic, any agreement extending the period for assessment
          or collection of any income or other taxes, is not a party to any
          pending action or proceeding by any foreign or domestic governmental
          agencies for the assessment or collection of taxes, and no claims for
          assessment or collection of taxes have been asserted against the
          Company or any of the Subsidiaries that might materially adversely
          affect the general affairs, assets, properties, assets, condition
          (financial or otherwise), results of operations, stockholders' equity,
          business or prospects of the Company and the Subsidiaries.

             (xvii)   To the best of the Company's knowledge, Ernst & Young LLP,
          which has certified certain financial statements of the Company and
          its consolidated subsidiaries and of Flam & Russell including in the
          Registration Statement and the Prospectus, are independent public
          accountants as required by the Act, the Exchange Act and the
          Regulations. The statements included in the Registration Statement
          with respect to Ernst & Young LLP pursuant to Rule 509 of Regulation
          S-K are true and correct in all material respects.

            (xviii)   Neither the Company nor any of the Subsidiaries is, or
          with the giving of notice or the passage of time or both would be, in
          violation of, or in default under, any of the terms or provisions of
          (A) its Certificate of Incorporation or By-laws, as amended to the
          date hereof, or (B) except to the extent such action would not have a
          material adverse effect on the general affairs, properties, assets,
          condition (financial or otherwise), results of operations,
          stockholders' equity, business or prospects of the Company and the
          Subsidiaries, (1) any indenture, mortgage, deed of trust, contract,
          loan agreement, commitment or other agreement or instrument to which
          it is a party or by which it or any of its properties is bound or
          affected; (2) any law, rule, regulation, judgment, order or decree of
          any government or governmental agency, instrumentality or court,
          domestic or foreign, having jurisdiction over it or any of its
          properties or business or (3) any license, permit, certification,
          registration, approval, consent or franchise referred to in subsection
          (iii) of this Section 1(a).

              (xix)   Other than as disclosed in the Prospectus, there are no
          claims, actions, suits, proceedings, arbitrations, investigations or
          inquiries pending before or, to the knowledge of the Company,
          threatened or contemplated by, any governmental agency,
          instrumentality, court or tribunal, domestic or foreign, or before any
          private arbitration tribunal, relating to or affecting the Company or
          any of the Subsidiaries or any of their respective properties or
          business that might affect the issuance or validity of any of the
          Shares or the validity of any of the outstanding

                                      -9-
<PAGE>
 
          Common Shares, or that, if determined adversely to the Company, would,
          in any case or in the aggregate, result in any material adverse change
          in the general affairs, properties, assets, condition (financial or
          otherwise), results of operations, stockholders' equity, business or
          prospects of the Company and the Subsidiaries; nor, to the knowledge
          of the Company, is there any reasonable basis for any such claim,
          action, suit, proceeding, arbitration, investigation or inquiry. There
          are no outstanding orders, judgments or decrees of any court,
          governmental agency, instrumentality or other tribunal enjoining the
          Company or any Subsidiary from, or requiring the Company to take or
          refrain from taking, any action, or to which the Company or any
          Subsidiary, or their respective properties, assets or business is
          bound or subject.

               (xx)   Except as disclosed in the Prospectus, the Company and
          each of the Subsidiaries owns, or possesses adequate rights to use,
          all patents, patent applications, trademarks, trademark registrations,
          applications for trademark registration, trade names, service marks,
          licenses, inventions, copyrights, know-how (including trade secrets
          and other unpatented and/or unpatentable proprietary or confidential
          technology, information, systems, design methodologies and devices or
          procedures developed or derived from the Company's or a Subsidiary's
          business), trade secrets, confidential information, processes and
          formulations necessary for, used in or proposed to be used in the
          conduct of its business as described in the Prospectus (collectively,
          the "Intellectual Property") that, if not so owned, would materially
          adversely affect the general affairs, properties, condition (financial
          or otherwise), results of operations, stockholders' equity, business
          or prospects of the Company and the Subsidiaries; neither the Company
          nor any of the Subsidiaries has knowingly infringed, is infringing or
          has received any notice of conflict with the asserted rights of others
          with respect to the Intellectual Property that, individually or in the
          aggregate, if the subject of an unfavorable decision, ruling or
          finding, would materially adversely affect the general affairs,
          properties, condition (financial or otherwise), results of operations,
          stockholders' equity, business or prospects of the Company and the
          Subsidiaries, and the Company does not know of any reasonable basis
          therefor; and, to the knowledge of the Company, no others have
          infringed upon or are in conflict with its Intellectual Property.

              (xxi)  The Company and each of the Subsidiaries has good and
          marketable title to all personal property (tangible and intangible)
          described in the Prospectus as being owned by it, free and clear of
          all liens, security interests, charges or encumbrances, except such as
          are described in the Prospectus or such as do not materially affect
          the value or the transferability of such property and do not

                                      -10-
<PAGE>
 
          interfere in any material respect with the use made, or proposed to be
          made, of such property by the Company or such Subsidiary. The Company
          and each of the Subsidiaries has adequately insured with insurers of
          recognized financial responsibility its personal property against loss
          or damage by fire or other casualty and maintains, in adequate
          amounts, insurance against such other risks as are prudent and
          customary in the businesses in which they are engaged. The Company
          does not own any real property, and all real property used or leased
          by the Company or any of the Subsidiaries, as described in the
          Prospectus (collectively, the "Premises"), is held by the Company or
          such Subsidiary under a valid, subsisting and enforceable lease. The
          Premises, and all operations conducted thereon, are now and, since the
          Company or such Subsidiary began to use such Premises, always have
          been and, to the knowledge of the Company, prior to when the Company
          or such Subsidiary began to use such Premises, always had been, in
          compliance with all federal, state and local statutes, ordinances,
          regulations, rules, standards and requirements of common law
          concerning or relating to industrial hygiene and the protection of
          health and the environment (collectively, "the Environmental Laws"),
          except to the extent that any failure to be in such compliance would
          not materially adversely affect the general affairs, properties,
          condition (financial or otherwise), results of operations,
          stockholders' equity, business or prospects of the Company and the
          Subsidiaries. To the knowledge of the Company, there are no conditions
          on, about, beneath or arising from the Premises that might give rise
          to liability, the imposition of a statutory lien or require a
          "Response," "Removal" or "Remedial Action," as defined herein, under
          any of the Environmental Laws, and that would materially adversely
          affect the general affairs, properties, condition (financial or
          otherwise), results of operations, stockholders' equity, business or
          prospects of the Company and the Subsidiaries. Neither the Company nor
          any of the Subsidiaries has received notice, and does not have actual
          or constructive knowledge, of any claim, demand, investigation,
          regulatory action, suit or other action instituted or threatened
          against it or the Premises relating to any of the Environmental Laws.
          Neither the Company nor any of the Subsidiaries has received any
          notice of material violation, citation, complaint, order, directive,
          request for information or response thereto, notice letter, demand
          letter or compliance schedule to or from any governmental or
          regulatory agency arising out of or in connection with Hazardous
          Substances (as defined by applicable Environmental Laws) on, about,
          beneath, arising from or generated at the Premises. As used in this
          subsection, the terms "Response," "Removal" and "Remedial Action"
          shall have the respective meanings assigned to such terms under
          Sections 101 (23)-101 (25) of the Comprehensive Environmental
          Response, Compensation and Liability Act, as amended by the Superfund
          Amendments and Reauthorization Act.

<PAGE>
 
             (xxii)   Each of the Company and the Subsidiaries maintains a
          system of internal accounting controls sufficient to provide
          reasonable assurances that: (A) transactions are executed in
          accordance with management's general or specific authorization; (B)
          transactions are recorded as necessary in order to permit preparation
          of the Company's consolidated financial statements in accordance with
          generally accepted accounting principles and to maintain
          accountability for assets; (C) access to assets is permitted only in
          accordance with management's general or specific authorization and (D)
          the recorded accountability for assets is compared with existing
          assets at reasonable intervals and appropriate action is taken with
          respect to any differences.

            (xxiii)   All offers and sales of the Company's capital stock prior
          to the date hereof were at all relevant times duly registered under
          the Act or exempt from the registration requirements of the Act by
          reasons of Sections 3(b), 4(2) or 4(6) thereof and were duly
          registered or the subject of an available exemption from the
          registration requirements of applicable state securities or blue sky
          laws.

             (xxiv)   Each contract or other instrument (however characterized
          or described) to which the Company or any of the Subsidiaries is a
          party or by which any of its properties or business is bound or
          affected and to which reference has been made in the Prospectus or
          which has been filed as an exhibit to the Registration Statement has
          been duly and validly executed by the Company or such Subsidiary and,
          to the knowledge of the Company, by the other parties thereto. Except
          as described in the Prospectus, each such contract or other instrument
          is in full force and effect in all material respects and, to the
          knowledge of the Company, is enforceable against the parties thereto
          in all material respects in accordance with its terms, and neither the
          Company nor such Subsidiary is and, to the knowledge of the Company,
          no other party is in material default thereunder and no event has
          occurred that, with the lapse of time or the giving of notice, or
          both, would constitute a material default thereunder.

              (xxv)   Except for the Company's 401(k), disability, health and
          life insurance plans, neither the Company nor any Subsidiary has had
          any employee benefit plan, profit sharing plan, employee pension
          benefit plan or employee welfare benefit plan or deferred compensation
          arrangements (collectively, "Plans") that are subject to the
          provisions of the Employee Retirement Income Security Act of 1974, as
          amended, or the rules and regulations thereunder ("ERISA"). All Plans
          that are subject to ERISA are, and have been at all times since their
          establishment, in compliance with ERISA in all material respects and,
          to the extent required by the Internal Revenue Code of 1986, as
          amended (the "Code"), in compliance with the Code in all material re-

          spects. Neither the Company nor any Subsidiary has had any employee
          pension benefit plan that is subject to Part 3 of Subtitle B of Title
          I of ERISA or any defined benefit plan or multiemployer plan. Neither
          the Company nor any Subsidiary has maintained retired life and retired
          health insurance plans that are employee welfare benefit plans
          providing for continuing benefit or coverage for any employee or any
          beneficiary of any employee after such employee's termination of
          employment, except as required by Section 4980B of the Code. To the
          knowledge of the Company, no fiduciary or other party in interest with
          respect to any of the Plans has caused any of such Plans to engage in
          a prohibited action as defined in Section 406 of ERISA. As used in
          this subsection, the terms "defined benefit plan," "employee benefit
          plan," "employee pension benefit plan," "employee welfare benefit
          plan," "fiduciary" and "multiemployer plan" shall have the respective
          meanings assigned to such terms in Section 3 of ERISA.

             (xxvi)   No labor dispute exists with the employees of the Company
          or any of the Subsidiaries and, to the knowledge of the Company, no
          such labor dispute is imminent. The Company is not aware of any
          existing or imminent labor disturbance by the employees of any of its
          principal suppliers, contractors or customers that would materially
          adversely affect the general affairs, properties, condition (financial
          or otherwise), results of operations, stockholders' equity, business
          or prospects of the Company and the Subsidiaries.

            (xxvii)   Except as disclosed in the Prospectus, the Company has not
          incurred any liability for any finder's fees or similar payments in
          connection with the transactions contemplated herein.

           (xxviii)   Except as described in the Prospectus, neither the Company
          nor any Subsidiary is a party to, nor is it bound by, any agreement
          pursuant to which royalties, honoraria or fees are payable by the
          Company or such Subsidiary to any person by reason of the ownership or
          use of any Intellectual Property that is material to the business of
          the Company or such Subsidiary.

             (xxix)   The Company is familiar with the Investment Company Act of
          1940, as amended (the "1940 Act"), and the rules and regulations
          thereunder, and has in the past conducted, and intends in the future
          to continue to conduct, its affairs in such a manner to ensure that it
          will not become an "investment company" within the meaning of the 1940
          Act and such rules and regulations.

              (xxx)   Neither the Company nor any of its officers, directors or
          affiliates has (A) taken, directly or indirectly, any action designed
          to cause or result in, or that has constituted or might reasonably be
          expected to consti-

                                      -13-

          tute, the stabilization or manipulation of the price of any security
          of the Company to facilitate the sale or resale of the Shares or (B)
          since the filing of the Registration Statement (1) sold, bid for,
          purchased or paid anyone any compensation for soliciting purchases of,
          the Shares or (2) paid or agreed to pay to any person any compensation
          for soliciting another to purchase any other securities of the
          Company.

             (xxxi)   The Company has obtained for the benefit of the Company
          and the Underwriters from the Selling Stockholder and each of the
          Company's directors and executive officers a written agreement that
          for a period of 180 days from the date of the Prospectus such Selling
          Stockholder, director or executive officer will not, without the prior
          written consent of the Representatives, offer, sell, contract to sell,
          grant any option for the sale of, or otherwise dispose of, directly or
          indirectly, any shares of Common Stock.

            (xxxii)   Neither the Company, any of the Subsidiaries, nor any
          director, officer, employee or other person associated with or acting
          on behalf of the Company or any Subsidiary has, directly or
          indirectly: used any corporate funds for unlawful contributions,
          gifts, entertainment or other unlawful expenses relating to political
          activity; made any unlawful payment to foreign or domestic government
          officials or employees or to foreign or domestic political parties or
          campaigns from corporate funds; violated any provision of the Foreign
          Corrupt Practices Act of 1977, as amended; or made any bribe, rebate,
          payoff, influence payment, kickback or other unlawful payment.

          Any certificate signed by any officer of the Company in such capacity
     and delivered to the Representatives or to counsel for the Underwriters
     pursuant to this Agreement shall be deemed a representation and warranty by
     the Company to the several Underwriters as to the matters covered thereby.

          (b)   Representations and Warranties of the Selling Stockholder. The
     Selling Stockholder represents and warrants to, and agrees with, each of
     the several Underwriters and the Company that:

                (i)   The Selling Stockholder is a corporation in good standing
          under the laws of the State of Israel. The Selling Stockholder has

          as described in the Prospectus and is duly qualified to do business in
          each jurisdiction in which it owns or leases real property or in which
          the conduct of its business requires such qualification.

               (ii)   The Selling Stockholder has full right, power (corporate
          and other) and authority to enter into this

                                      -14-

          Agreement and the Agreement and Power of Attorney and to sell, assign,
          transfer and deliver to the Underwriters the Shares to be sold by the
          Selling Stockholder hereunder; and the execution and delivery of this
          Agreement and the Agreement and Power of Attorney have been duly
          authorized by all necessary action of the Selling Stockholder.

              (iii)   The Selling Stockholder has duly executed and delivered
          this Agreement and the Agreement and Power of Attorney and, assuming
          due execution of this Agreement by the Representatives of the
          Underwriters, this Agreement and the Agreement and Power of Attorney
          constitute the valid and binding agreements of the Selling Stockholder
          enforceable against the Selling Stockholder in accordance with its
          terms, subject, as to enforcement, to applicable bankruptcy,
          insolvency, reorganization and moratorium laws and other laws relating
          to or affecting the enforcement of creditors' rights generally and to
          general equitable principles and, with respect to this Agreement and
          the Agreement and Power of Attorney, except as the enforceability of
          rights to indemnity and contribution under this Agreement may be
          limited under applicable securities laws or the public policy
          underlying such laws.

               (iv)   No consent, approval, authorization, order or declaration
          of or form, or registration, qualification or filing with, any court
          or governmental agency or body is required for the sale of the Shares
          to be sold by the Selling Stockholder or the consummation of the
          transactions contemplated by this Agreement and the Agreement and
          Power of Attorney, except the registration of such Shares under the
          Act (which, if the Registration Statement is not effective as of the
          time of execution hereof, shall be obtained as provided in this
          Agreement) and such as may be required under state securities or blue
          sky laws in connection with the offer, sale and distribution of such
          Shares by the Underwriters.

                (v)   The sale of the Shares to be sold by the Selling
          Stockholder and the performance of this Agreement and the Agreement
          and the Power of Attorney and the consummation of the transactions
          therein and herein contemplated will not conflict with, or, with or
          without the giving of notice or the passage of time or both, result in
          a breach or violation of any of the terms or provisions of, or
          constitute a default under, any indenture, mortgage, deed of trust,
          loan agreement, lease or other agreement or instrument to which the
          Selling Stockholder or any of its subsidiaries is a party or to which
          any of their respective properties or assets is subject, nor will such
          action conflict with or violate any provision of the charter documents
          or by-laws of the Selling Stockholder or governing instruments of any
          of its subsidiaries or any statute, rule or regulation or any order,
          judgement or decree of any court or governmental agency or body having
          jurisdiction over the Selling Stock-

                                      -15-
<PAGE>
 
          holder or any of the Selling Stockholder's properties or assets.

               (vi)   The Selling Stockholder has, and immediately prior to the
          Option Closing Date (as defined in Section 4 hereof), the Selling
          Stockholder will have, good and valid title to the Shares to be sold
          by the Selling Stockholder hereunder, free and clear of all liens,
          security interests, pledges, charges, encumbrances, defects,
          shareholders' agreements, voting trusts, equities or claims of any
          nature whatsoever (other than pursuant to the Agreement and Power of
          Attorney); and, upon delivery of such Shares against payment therefor
          as provided herein, good and valid title to such Shares, free and
          clear of all liens, security interests, pledges, charges,
          encumbrances, defects, stockholders' agreements, voting trusts,
          equities or claims of any nature whatsoever, will pass to the several
          Underwriters.

              (vii)   Neither the Selling Stockholder nor any of its officers,
          directors or affiliates has (A) taken, directly or indirectly, any
          action designed to cause or result in, or that has constituted or
          might reasonably be expected to constitute, the stabilization or
          manipulation of the price of any security of the Company to facilitate
          the sale or resale of the Shares or (B) since the filing of the
          Registration Statement (1) sold, bid for, purchased or paid anyone any
          compensation for soliciting purchases of, the Shares or (2) paid or
          agreed to pay to any person any compensation for soliciting another to
          purchase any other securities of the Company.

             (viii)   To the best knowledge of the Selling Stockholder, the
          representations and warranties of the Company contained in Section
          1(a) hereof are true and correct.

               (ix)   When any Preliminary Prospectus was filed with the SEC it
          (A) contained all statements required to be stated therein in
          accordance with, and complied in all material respects with the
          requirements of, the Act and the Regulations thereunder, and (B) did
          not include any untrue statement of a material fact or omit to state
          any material fact necessary in order to make the statements therein,
          in the light of the circumstances under which they were made, not
          misleading. When the Registration Statement or any amendment thereto
          was or is declared effective and at the Option Closing Date, it (A)
          contained or will contain all statements required to be stated therein
          in accordance with, and complied or will comply in all material
          respects with the requirements of, the Act and the Regulations
          thereunder and (B) did not or will not include any untrue statement of
          a material fact or omit to state any material fact necessary to make
          the statements therein not misleading. When the Prospectus or any
          amendment or supplement thereto is filed with the SEC pursuant to Rule
          424(b) (or,

                                      -16-
<PAGE>
 
          if the prospectus or such amendment or supplement is not required to
          be so filed, when the Registration Statement or the amendment thereto
          containing such amendment or supplement to the Prospectus was or is
          declared effective), and at the Option Closing Date, the Prospectus,
          as amended or supplemented at any such time, (A) contained or will
          contain all statements required to be stated therein in accordance
          with, and complied or will comply in all material respects with the
          requirements of, the Act and the Regulations thereunder and (B) did
          not or will not include any untrue statement of a material fact or
          omit to state any material fact necessary in order to make the
          statements therein, in the light of the circumstances under which they
          were made, not misleading. The foregoing provisions of this paragraph
          (viii) do not apply to statements or omissions made in any Preliminary
          Prospectus, the Registration Statement or any amendment thereto or the
          Prospectus or any amendment or supplement thereto in reliance upon and
          in conformity with written information furnished to the Company by any
          Underwriter through the Representatives specifically for use therein.

                (x)   Certificates in negotiable form for the Optional shares to
          be sold hereunder by the Selling Stockholder have been placed in
          custody, for the purpose of making delivery of such Optional Shares
          under this Agreement, under the Agreement and Power of Attorney which
          appoints ___________ as custodian (the "Custodian") for the Selling
          Stockholder. The Selling Stockholder agrees that the Optional Shares
          represented by the certificates held in custody for it under the
          Agreement and Power of Attorney are for the benefit of and coupled
          with and subject to the interest hereunder of the Custodian, the
          Underwriters and the Company, that the arrangements made by the
          Selling Stockholder for such custody and the appointment of the
          Custodian by the Selling Stockholder are irrevocable, and that the
          obligations of the Selling Stockholder hereunder shall not be
          terminated by operation of law, the liquidation of the Selling
          Stockholder or any other event, and after any such liquidation or
          event, certificates for the Optional Shares shall be delivered by the
          Custodian in accordance with the terms and conditions of this
          Agreement and any actions taken by the Custodian pursuant to the
          Agreement and Power of Attorney shall be as valid as if such
          liquidation or other event had not occurred, regardless of whether or
          not the Custodian shall have received notice thereof.

          In order to document the Underwriters' compliance with the reporting
     and withholding provisions of the Code, with respect to the transactions
     herein contemplated, the Selling Stockholder agrees to deliver to the
     Representatives prior to or at the Option Closing Date, a properly
     completed and executed United States Treasury Department Form W-9 or other
     applicable form or statement specified by Treasury Department regulations
     in lieu thereof.

representations, warranties, covenants and agreements herein contained, but
subject to the terms and conditions herein set forth, the Company shall sell the

underwriting discount shown on the cover page of the Prospectus (the
"Underwriting Discount"), and the Underwriters, severally and not jointly,
shall purchase from the Company on a firm commitment basis, at the Offering
Price less the Underwriting Discount, the respective Offered Shares set forth
opposite their names on Schedule I hereto.  In making this Agreement, each 
Underwriter is contracting severally, and not jointly, and except as provided in

     3. Payment and Delivery. Payment for the Offered Shares shall be made to

4200 One Liberty Place, Philadelphia, Pennsylvania 19103, or at such other

immediately available funds wired to such account as the Company may specify
(with all costs and expenses incurred by the Underwriters in connection with
such settlement in immediately available funds (including, but not limited to,
interest or cost of funds expenses) to be borne by the Company), against
delivery of the Offered Shares to the Representatives at the offices of The
Depository Trust Company, 55 Water Street, New York, New York 10041, for the
respective accounts of the Underwriters. Such payment and delivery will be made
at 10:00 A.M., Philadelphia time, on the fifth business day after the date of
this Agreement or at such other time and date not later than five business days
thereafter as the Representatives and the Company shall agree upon. Such time
and date are referred to herein as the "Closing Date." The certificates
representing the Offered Shares to be sold and delivered will be in such
denominations and registered in such names as the Representatives request not
less than two full business days prior to the Closing Date, and will be made
available to the Representatives for inspection, checking and packaging at the
office of The Depository Trust Company in New York, New York or at such other
location in New York, New York as is specified by the Representatives, not less
than one full business day prior to the Closing Date.

     4.    Option to Purchase Optional Shares.

           (a) For the purposes of covering any over-allotments in connection
     with the distribution and sale of the Offered Shares as contemplated by the
     Prospectus, subject to the terms and conditions herein set forth, the
     several Underwriters are hereby granted an option by the Selling
     Stockholder to purchase all or any part of the Optional Shares from the
     Selling Stockholder (the "Over-allotment Option"). The purchase price to be
     paid for the Optional Shares shall be the Offering Price less the 

                                      -18-
<PAGE>
 
     Underwriting Discount. The Over-allotment Option granted hereby may be
     exercised by the Representatives on behalf of the several Underwriters as
     to all or any part of the Optional Shares at any time and from time to time
     within 30 business days after the Effective Date. No Underwriter shall be
     under any obligation to purchase any Optional Shares prior to an exercise
     of the Over-allotment Option.

           (b) The Over-allotment Option granted hereby may be exercised by the
     Representatives on behalf of the several Underwriters by giving notice to
     the Selling Stockholder by a letter sent by registered or certified mail,
     postage prepaid, telex, telegraph, telegram or facsimile (such notice to be
     effective when sent), addressed as provided in Section 13 hereof, setting
     forth the number of Optional Shares to be purchased, the date and time for
     delivery of and payment for the Optional Shares and stating that the
     Optional Shares referred to therein are to be used for the purpose of
     covering over-allotments in connection with the distribution and sale of
     the Offered Shares. If such notice is given prior to the Closing Date, the
     date set forth therein for such delivery and payment shall not be earlier
     than either five full business days thereafter or the Closing Date,
     whichever occurs later. If such notice is given on or after the Closing
     Date, the date set forth therein for such delivery and payment shall be a
     date selected by the Representatives that is not later than five full
     business days after the exercise of the Over-allotment Option. The date and
     time set forth in such a notice is referred to herein as an "Option Closing
     Date," and a closing held pursuant to such a notice is referred to herein
     as an "Option Closing." The number of Optional Shares to be sold to each
     Underwriter pursuant to each exercise of the Over-allotment Option shall be
     the number that bears the same ratio to the aggregate number of Optional
     Shares being purchased through such Over-allotment Option exercise as the
     number of Offered Shares opposite the name of such Underwriter in Schedule
     I hereto bears to the total number of all Offered Shares; subject, however,
     to such adjustment as the Representatives may approve to eliminate
     fractional shares and subject to the provisions for the allocation of
     Optional Shares purchased for the purpose of covering over-allotments set
     forth in Sections 9 and 12 of the Agreement Among Underwriters. Upon each
     exercise of the Over-allotment Option, the Selling Stockholder shall become
     obligated to issue and sell to the Representatives for the respective
     accounts of the Underwriters, and on the basis of the representations,
     warranties, covenants and agreements herein contained, but subject to the
     terms and conditions herein set forth, the several Underwriters shall
     become severally but not jointly obligated to purchase from the Selling
     Stockholder, the number of Optional Shares specified in each notice of
     exercise of the Over-allotment Option.

           (c) Payment for the Optional Shares shall be made to the Selling
     Stockholder by certified or official bank check payable to its order in
     Philadelphia Clearing House funds, at the offices of Duane, Morris &
     Heckscher, 4200 One Liberty Place, 

                                      -19-

     Philadelphia, PA 19103, or such other location as shall be agreed upon by
     the Selling Stockholder and the Representatives, or in immediately
     available funds wired to such account as the Selling Stockholder may
     specify (with all costs and expenses incurred by the Underwriters in
     connection with such settlement in immediately available funds (including,
     but not limited to, interest or cost of funds expenses) to be borne by the
     Selling Stockholder), against delivery of the Optional Shares to the
     Representatives at the offices of The Depository Trust Company, 55 Water
     Street, New York, New York 10041, for the respective accounts of the
     Underwriters. The certificates representing the Optional Shares to be
     issued and delivered will be in such denominations and registered in such
     names as the Representatives request not less than two full business days
     prior to the Option Closing Date, and will be made available to the
     Representatives for inspection, checking and packaging at the office of
     The Depository Trust Company in New York, New York or at such other
     location in New York, New York as is specified by the Representatives not
     less than one full business day prior to the Option Closing Date.

     5.   Certain Covenants and Agreements of the Company and the Selling
Stockholder.

           (a)   Covenants of the Company. The Company covenants and agrees
     with the several Underwriters as follows:

                 (i) If Rule 430A of the Regulations is employed, the Company
           will timely file the Prospectus pursuant to and in compliance with
           Rule 424(b) of the Regulations and will advise the Representatives of
           the time and manner of such filing.

                 (ii) The Company will not at any time, whether before or after
           the Registration Statement shall have become effective, during such
           period as, in the opinion of counsel for the Underwriters, the
           Prospectus is required by law to be delivered in connection with
           sales by the Underwriters or a dealer, file or publish any amendment
           or supplement to the Registration Statement or the Prospectus of
           which the Representatives have not been previously advised and 
           furnished a copy, or which is not in compliance with the Regulations,
           or, during the period before the distribution of the Offered Shares
           and the Optional Shares is completed, file or publish any amendment
           or supplement to the Registration Statement or the Prospectus to
           which the Representatives reasonably object in writing.

                 (iii) The Company will use its best efforts to cause the
           Registration Statement, if not effective at the time and date that
           this Agreement is executed and delivered by the parties hereto, to
           become effective and will advise the Representatives immediately, and
           confirm such advice in writing, (A) when the Registration Statement,
           or any post-effective amendment to the Registration Statement, is
           filed 

                                      -20-
<PAGE>
 
           with the SEC, (B) of the receipt of any comments from the SEC, (C)
           when the Registration Statement has become effective and when any
           post-effective amendment thereto becomes effective, or when any
           supplement to the Prospectus or any amended Prospectus has been
           filed, (D) of any request of the SEC for amendment or supplementation
           of the Registration Statement or Prospectus or for additional
           information, (E) during the period when the Prospectus is required to
           be delivered under the Act and Regulations, of the happening of any
           event which in the Company's judgment makes any material statement in
           the Registration Statement or the Prospectus untrue or which requires
           any changes to be made in the Registration Statement or the
           Prospectus in order to make any material statements therein not
           misleading and (F) of the issuance by the SEC of any stop order
           suspending the effectiveness of the Registration Statement or of any
           order preventing or suspending the use of any Preliminary Prospectus
           or the Prospectus, the suspension of the qualification of any of the
           Shares for offering or sale in any jurisdiction in which the
           Underwriters intend to make such offers or sales, or of the
           initiation or threatening of any proceedings for any of such
           purposes. The Company will use its best efforts to prevent the
           issuance of any such stop order or of any order preventing or
           suspending such use and, if any such order is issued, to obtain as
           soon as possible the lifting thereof.

                 (iv) The Company has delivered to the Representatives, without
           charge, and will continue to deliver from time to time until the
           Effective Date, as many copies of each Preliminary Prospectus as the
           Representatives may reasonably request. The Company will deliver to
           the Representatives, without charge, as soon as possible after the
           Effective Date, and thereafter from time to time during the period
           when delivery of the Prospectus is required under the Act, such
           number of copies of the Prospectus (as supplemented or amended, if
           the Company makes any supplements or amendments to the Prospectus) as
           the Representatives may reasonably request. The Company hereby
           consents to the use of such copies of the Preliminary Prospectus and
           the Prospectus for the purposes permitted by the Act, the Regulations
           and the securities or Blue Sky laws of the jurisdictions in which the
           Shares are offered by the several Underwriters and by all dealers to
           whom Shares may be sold, both in connection with the offering and
           sale of the Shares and for such period of time thereafter as the
           Prospectus is required by the Act to be delivered in connection with
           sales by any Underwriter or dealer. The Company has furnished or will
           furnish to the Representatives two signed copies of the Registration
           Statement as originally filed and of all amendments thereto, whether
           filed before or after the Effective Date, two copies of all exhibits
           filed therewith and two signed copies of all consents and
           certificates of experts, and will deliver to the Representatives such
           number of conformed copies of the Registration State-
                                      -21-
<PAGE>
 
           ment, including financial statements and exhibits, and all
           amendments thereto, as the Representatives may reasonably request.

                 (v) The Company will comply with the Act, the Regulations, the
           Exchange Act and the rules and regulations thereunder so as to permit
           the continuance of sales of and dealings in the Shares for as long as
           may be necessary to complete the distribution of the Shares as
           contemplated hereby. The Company will comply with all of the
           provisions of any undertakings contained in the Registration 
           Statement.

                 (vi) The Company will furnish such information as may be
           required and otherwise cooperate in the registration or qualification
           of the Shares, or exemption therefrom, for offering and sale by the
           several Underwriters and by dealers under the securities or Blue Sky
           laws of such jurisdictions in which the Representatives determine to
           offer the Shares, after consultation with the Company, and will file
           such consents to service of process or other documents necessary or
           appropriate in order to effect such registration or qualification;
           provided, however, that no such qualification shall be required in
           any jurisdiction where, solely as a result thereof, the Company would
           be subject to taxation or qualification as a foreign corporation
           doing business in such jurisdiction where it is not now so qualified
           or to take any action which would subject it to service of process
           in suits, other than those arising out of the offering or sale of the
           Shares, in any jurisdiction where it is not now so subject. The
           Company will, from time to time, prepare and file such statements and
           reports as are or may be required to continue such qualification in
           effect for so long a period as is required under the laws of such
           jurisdictions for such offering and sale.

                 (vii) Subject to subsection (ii) of this Section 5(a), in case
           of any event, at any time within the period during which, in the
           opinion of counsel for the Underwriters, a prospectus is required to
           be delivered under the Act and the Regulations, as a result of which
           event any Preliminary Prospectus or the Prospectus, as then amended
           or supplemented, would contain in the judgment of the Company or in
           the opinion of counsel for the Underwriters an untrue statement of a
           material fact, or omit to state any material fact necessary in order
           to make the statements therein, in light of the circumstances under
           which they were made, not misleading, or, if it is necessary at any
           time to amend any Preliminary Prospectus or the Prospectus to comply
           with the Act and the Regulations or any applicable securities or Blue
           Sky laws, the Company promptly will prepare and file with the SEC,
           and any applicable state securities commission, an amendment or
           supplement that will correct such statement or omission or an
           amendment that will effect such compliance and will furnish to the
           Representatives such 

                                      -22-
<PAGE>
 
           number of copies of such amendment or amendments or supplement or
           supplements to the Prospectus, in form and substance satisfactory to
           the Representatives and counsel for the Underwriters, as the
           Representatives may reasonably request. For purposes of this
           subsection, the Company will furnish such information to the
           Representatives, the Underwriters' counsel and counsel to the
           Company as shall be necessary to enable such persons to consult with
           the Company with respect to the need to amend or supplement the
           Prospectus, and shall furnish to the Representatives and the
           Underwriters' counsel such further information as each may from time
           to time reasonably request. If the Company and the Representatives
           agree that the Prospectus should be amended or supplemented, the
           Company, if requested by the Representatives, will, if and to the
           extent required by law, promptly issue a press release announcing or
           disclosing the matters to be covered by the proposed amendment or
           supplement.

             (viii)  The Company will make generally available to its security
           holders as soon as practicable and in any event not later than 45
           days after the end of the period covered thereby, an earnings
           statement of the Company, which need not be audited unless required
           by the Act or the Regulations, that shall comply with Section 11(a)
           of the Act and Rule 158 under the Regulations and cover a period of
           at least 12 consecutive months beginning not later than the first day
           of the Company's fiscal quarter next following the Effective Date.

               (ix)  For a period of five years from the Effective Date, the
           Company will deliver to the Representatives: (i) a copy of each
           report or document, including, without limitation, reports on Forms 
           8-K, 10-Q and 10-K (or such similar forms as may be designated by the
           SEC), registration statements and any exhibits thereto, filed or
           furnished to the SEC or any securities exchange or the NASD, on the
           date each such report or document is so filed or furnished; (ii) as
           soon as practicable, copies of any reports or communications
           (financial or other) of the Company mailed to its security holders
           and (iii) every material press release in respect of the Company or
           its affairs that was released or prepared by the Company.

                (x)  For a period of three years from the Effective Date, the
           Company will deliver to the Representatives, subject to execution of
           an appropriate confidentiality agreement, such additional information
           concerning the business and financial condition of the Company as the
           Representatives may from time to time reasonably request in writing,
           and which can be prepared or obtained by the Company without
           unreasonable effort or expense.

               (xi)  Neither the Company nor any of its officers, directors or
           affiliates will (A) take, directly or indi-

                                      -23-

           rectly, prior to the termination of the underwriting syndicate
           contemplated by this Agreement, any action designed to cause or to
           result in, or that might reasonably be expected to constitute, the
           stabilization or manipulation of the price of any security of the
           Company to facilitate the sale or resale of the Shares, (B) sell, bid
           for, purchase or pay anyone any compensation for soliciting purchases
           of, the Shares or (C) pay or agree to pay to any person any
           compensation for soliciting another to purchase any other securities
           of the Company.

               (xii)  The Company will cause each person listed on Schedule II
           hereto to execute a legally binding and enforceable agreement (a
           "lock-up agreement") in the form of Exhibit C hereto to, for a period
           of 180 days from the Effective Date, not sell, offer to sell,
           contract to sell, grant any option for the sale of or otherwise
           transfer or dispose of any Common Shares, any options to purchase
           Common Shares or any securities convertible into or exchangeable for
           Common Shares (excluding the issuance of Common Shares pursuant to
           the Employee Options) without the prior written consent of the
           Representatives, which consent will not be unreasonably withheld,
           which lock-up agreement shall be in form and substance satisfactory
           to the Representatives and the Underwriters' counsel, and shall
           deliver such agreement to the Representatives prior to the Effective
           Date. Appropriate stop transfer instructions with respect to any
           Common Shares held by such person will be issued by the Company to
           the transfer agent for the Common Shares.

              (xiii)  The Company will not sell, issue, contract to sell, offer
           to sell or otherwise dispose of any Common Shares, options to
           purchase Common Shares or any other security convertible into or
           exchangeable for Common Shares, from the date of the Effective Date
           through the period ending 180 days after the Effective Date, without
           the prior written consent of the Representatives, which consent shall
           not be unreasonably withheld, except for (i) the sale of the Shares
           as contemplated by this Agreement and the granting of options, (ii)
           the issuance of Common Shares upon the exercise of options under the
           Company's 1997 Equity Incentive Plan described in the Prospectus
           and (iii) in connection with the acquisition of AEMI.

               (xiv)  The Company will use all reasonable efforts to maintain
           the listing of the Common Shares on the Nasdaq NMS.

                (xv)  The Company shall, at its sole cost and expense, supply
           and deliver to the Representatives and the Underwriters' counsel (in
           the form they require), within a reasonable period from the Closing
           Date, six transaction binders, each of which shall include the
           Registration Statement, as amended or supplemented, all exhibits to
           the 

                                      -24-

           Registration Statement, the Prospectus, the Preliminary Blue Sky
           Memorandum and any supplement thereto and all other underwriting and
           closing documents.

                 (xvi) Upon the Representatives' request, individually and not

           make available its stock transfer records for examination by the
           Representatives at the offices of the Company's transfer agent for a
           period of 12 months after the Effective Date.

                 (xvii) The Company will use the net proceeds from the sale of
           the Shares to be sold by it hereunder substantially in accordance
           with the description set forth in the Prospectus and shall file such
           reports with the SEC with respect to the sale of such Shares and the
           application of the proceeds therefrom as may be required in
           accordance with Rule 463 under the Act.

                 (xviii) Following the Closing Date, the Company shall nominate
           as directors for election by the Company's stockholders and, to the
           extent permitted by applicable law, shall use its best efforts to
           effectuate such election so that for the three years following the
           Effective Date, the Company's Board of Directors shall include three
           individuals who are not affiliates of the Company or its affiliates.

                 (xix) If at any time during the period beginning on the
           Effective Date and ending on the later of (A) the date 30 days after

           reasonable opinion of the Representatives the market price of the
           Shares has been or is likely to be materially affected, regardless of
           whether such publication or event necessitates an amendment of or
           supplement to the Prospectus, the Company will, after written notice
           from the Representatives advising the Company to the effect set forth
           above, forthwith prepare, consult with the Representatives
           concerning the substance of, and disseminate a press release or other
           public statement, reasonably satisfactory to the Representatives,
           responding to or commenting on such publication or event and (y) any
           rumor relating to or affecting the Company shall occur as a result of
           which in the reasonable opinion of the Representatives the market
           price of the Shares has been or is likely to be materially affected,
           regardless of whether such rumor necessitates an amendment of or
           supplement to the Prospectus, the Company will consult with the
           Representatives concerning the necessity of a press release or other
           public statement, and, if 

                                      -25-

           the Company grants Pennsylvania Merchant Group Ltd the right of first
           refusal to act as the managing underwriter for any and all future
           public offerings (excluding offerings to Company employees or to
           others as consideration for the purchase of assets for use in the
           Company's business or in one or more business combinations) of any
           equity securities of the Company, or any successor to or any
           subsidiary of the Company. Pennsylvania Merchant Group Ltd shall
           notify the Company of the decision whether or not to exercise this
           right of first refusal within 30 days of receipt of written notice of
           the intention of the Company or its successor or subsidiary to offer
           equity securities for sale.

           Agreement, any action designed to cause or to result in, or that
           might reasonably be expected to constitute, the stabilization or
           manipulation of the price of any security of the Company to facili-
           tate the sale or resale of any of the Shares, (B) sell, bid for,
           purchase or pay anyone any compensation for soliciting purchases of,
           the Shares or (C) pay to or agree to pay any person any compensation
           for soliciting another to purchase any other securities of the
           Company.

                 (i) The Company has been incorporated and is validly existing
           and in good standing under the laws of Delaware, with corporate power
           and authority to own or lease and 

                                      -29-
<PAGE>
 
           operate its properties and to conduct its business as described in
           the Prospectus and to execute, deliver and perform this Agreement.
           The Company is duly qualified to do business as a foreign corporation
           and is in good standing in all jurisdictions in which it owns or
           leases properties, or conducts any business, so as to require such
           qualification, except where the failure so to qualify would not have
           a material adverse effect on the general affairs, properties,
           condition (financial or otherwise), results of operations,
           stockholders' equity or business of the Company. To the knowledge of
           Company Counsel, the Company does not own any stock or other equity
           interest in any corporation, partnership or other entity other than
           the Subsidiaries.

                 (ii) Each Subsidiary has been duly incorporated, is validly
           existing as a corporation in good standing under the laws of its
           jurisdiction of incorporation and has the corporate power and
           authority to own or lease its properties and conduct its business as
           described in the Prospectus. Each Subsidiary is duly qualified to
           transact business as a foreign corporation and is in good standing
           under the laws of each other jurisdiction in which it owns or leases
           property, or conducts any business, so as to require such
           qualification, except where the failure so to qualify would not have
           a material adverse effect on the general affairs, properties,
           condition (financial or otherwise), results of operations,
           stockholders' equity or business of the Company and its Subsidiaries.

                 (iii)  This Agreement has been duly authorized, executed and
           delivered by the Company.

                 (iv) The execution, delivery and performance of this Agreement
           by the Company and the Selling Stockholder does not and will not,
           with or without the giving of notice or the lapse of time, or both,
           (A) conflict with any terms or provisions of the Certificate of
           Incorporation or By-laws, as amended to the date hereof of each of
           the Company, the Selling Stockholder or the Subsidiaries; (B) result
           in a breach of, or constitute a default under, result in the
           termination or modification of or result in the creation or
           imposition of any lien, security interest, charge or encumbrance
           upon any of the properties of the Company, the Selling Stockholder or
           any Subsidiary pursuant to, any indenture, mortgage, deed of trust,
           contract, commitment or other agreement or instrument, known to
           Company Counsel, to which the Company, the Selling Stockholder or any
           Subsidiary is a party or by which any of the properties or assets of
           the Company, the Selling Stockholder or any Subsidiary is bound or
           subject or (C) violate any law, rule or regulation, or any judgment,
           order or decree, known to Company Counsel, of any government or
           governmental agency, instrumentality or court, domestic or foreign,
           having jurisdiction over the Company, the Selling Stockholder or any
           

                                      -30-
<PAGE>
 
           Subsidiary or any of the properties of the Company, the Selling
           Stockholder or any Subsidiary.

                 (v) The Company has the authorized and outstanding
           capitalization as set forth in the Prospectus. There are no options
           or warrants for the purchase of, other outstanding rights to
           purchase, agreements or obligations to issue or agreements or other
           rights to convert or exchange any obligation or security into,
           capital stock of the Company or securities convertible into or
           exchangeable for capital stock of the Company, except as described in
           the Registration Statement or the Prospectus.

                 (vi) The authorized capital stock of the Company, including,
           without limitation, the outstanding Common Shares and the Shares
           being issued on the Closing Date and any Option Closing Date,
           conforms in all material respects with the descriptions thereof in
           the Prospectus, and such descriptions conform in all material
           respects with the descriptions thereof set forth in the instruments
           defining the same. The information in the Prospectus insofar as it
           relates to the Employee Options is true and correct in all material
           respects.

                 (vii)  The Common Shares outstanding immediately prior to the
           Closing Date, including the Common Shares to be sold by the Selling
           Stockholder, have been duly authorized and are validly issued, fully
           paid and nonassessable; the Employee Options have been duly
           authorized and validly issued and are legal, valid and binding
           obligations, enforceable against the Company in accordance with
           their respective terms; the Common Shares issuable pursuant to the
           Employee Options, when issued in accordance with the respective terms
           thereof, will be duly authorized and validly issued, fully-paid and
           nonassessable; the Company has reserved a sufficient number of Common
           Shares for issuance pursuant to the Employee Options, and none of
           such outstanding Common Shares or Employee Options are, and none of
           such issuable Common Shares will be, issued in violation of any
           preemptive rights, known to Company Counsel, of any security holder
           of the Company that have not been waived.

                 (viii)  All of the issued shares of capital stock of each of
           the Subsidiaries have been duly authorized and validly issued, are
           fully paid and non-assessable, and, except for AEMI, are, and, in the
           case of AEMI, will be, owned beneficially by the Company free and
           clear of all liens, security interests, pledges, charges,
           encumbrances, stockholders agreements, voting trusts, defects,
           equities or claims of any nature whatsoever. To such counsel's
           knowledge, other than the subsidiaries listed on Exhibit 21.1 to the
           Registration Statement, the Company does not own, directly or
           indirectly, any capital stock or other equity securities of any other
           corporation or any ownership interest in any partnership, joint
           venture or other association.

                 (ix) The issuance and sale of the Shares by the Company have
           been duly authorized and, when the Shares have been duly delivered
           against payment therefor as contemplated by this Agreement, the
           Shares will be validly issued, fully paid and nonassessable. None of
           the Shares will be issued in violation of any preemptive rights of
           any stockholder of the Company pursuant to the Certificate of
           Incorporation or By-laws, as amended to the date hereof, of the
           Company and, to the knowledge of Company Counsel, there are no
           contractual preemptive rights that have not been waived that exist
           with respect to the Shares. The certificates representing the Shares
           are in proper legal form under, and conform in all respects to the
           requirements of, the DGCL. To the knowledge of Company Counsel,
           neither the filing of the Registration Statement nor the offering or
           sale of the Shares as contemplated by this Agreement gives any
           security holder of the Company any rights, other than those which
           have been waived, for or relating to the registration of any Common
           Shares and there are no contracts, agreements or understandings known
           to such counsel between the Company and any person granting such
           person the right to require the Company to file a registration
           statement under the Act with respect to any securities of the Company
           owned or to be owned by such person.

                 (x) No consent, approval, authorization, order, registration,
           license or permit of any court, government, governmental agency,
           instrumentality or other regulatory body or official is required for
           the valid authorization, issuance, sale and delivery by the Company
           or the Selling Stockholder of any of the Shares or for the execution,
           delivery or performance by the Company or the Selling Stockholder of
           this Agreement, except such as may be required for the registration
           of the Shares under the Act, the Regulations or the Exchange Act, or
           for compliance with the applicable state securities or Blue Sky laws,
           or the By-laws, rules and other pronouncements of the NASD.

                 (xi) The descriptions contained in the Registration Statement
           and the Prospectus of statutes or regulations, legal and governmental
           proceedings and of contracts and other documents are accurate in all
           material respects and fairly present in all material respects the
           information required to be shown. To Company Counsel's knowledge,
           there are no contracts, agreements or other documents required to be
           described or referred to in the Registration Statement or the
           Prospectus or to be filed as exhibits to the Registration Statement
           under the Act or the Regulations that have not been so described,
           referred to or filed as required.

                 (xii)  To Company Counsel's knowledge, there are no claims,
           actions, suits, proceedings, arbitrations, investigations or
           inquiries pending before, or threatened or contemplated by, any
           governmental agency, instrumentality, 

                                      -32-
<PAGE>
 
           court or tribunal, domestic or foreign, or before any private
           arbitration tribunal, to which the Company is a party or is
           threatened to be made a party that, if determined adversely to the
           Company, would, in any case or in the aggregate, result in any
           material adverse change in the general affairs, properties, condition
           (financial or otherwise), results of operations, stockholders'
           equity or business of the Company and the Subsidiaries.

                 (xiii)  The Registration Statement has become effective under
           the Act, as of the Effective Date, and, to Company Counsel's
           knowledge, the SEC has not issued any stop order suspending the
           effectiveness of the Registration Statement, nor has the SEC
           instituted or threatened to institute proceedings with respect to any
           such order. Any and all filings required to be made by Rule 424 and
           Rule 430A under the Act have been made.

                 (xiv)  The Registration Statement and the Prospectus, as of the
           Effective Date, and each amendment or supplement thereto as of its
           effective or issue date (except for the financial statements and
           notes thereto, and related schedules, included therein or omitted
           therefrom, as to which Company Counsel need not express an opinion)
           comply as to form in all material respects with the applicable
           requirements of the Act and Regulations.

                 (xv) The Company is not, and will not be as a result of the
           consummation of the transactions contemplated by this Agreement, an
           "investment company" or a company "controlled" by an "investment
           company" within the meaning of the Investment Company Act of 1940.

                 (xvi)  Company Counsel has participated in the preparation of
           the Registration Statement and the Prospectus, including reviews and
           discussions of the contents thereof, and while such Counsel has no
           particular expertise with respect to the financial statements and
           notes thereto and related schedules and the technical and scientific
           information contained in the Prospectus, and is not passing upon the
           accuracy or completeness of the statements contained in the
           Registration Statement or the Prospectus, other than those
           specifically referred to in the other clauses of this subsection (f)
           of this Section 7, in the course of such reviews and discussions, no
           facts came to its attention that would cause it to have reason to
           believe that (A) the Registration Statement or any post-effective
           amendment thereto, on the date it became effective and on the Closing
           Date or the Option Closing Date, as the case may be, contained any
           untrue statement of a material fact or omitted any material fact
           necessary to make the statements therein, in light of the
           circumstances under which they were made, not misleading or that (B)
           the Prospectus on the Effective Date, on the date it was filed
           pursuant to Rule 424(b) and on the Closing Date or Option Closing
           Date, as the case may

                                      -33-
<PAGE>
 
           be, contained any untrue statement of material fact or omitted any
           material fact necessary to make the statements therein, in light of
           the circumstances under which made, not misleading.

                 (xvii)  Nothing has come to the attention of Company Counsel
           which causes it to believe that there exists any defect in title or
           leasehold interest, or any lien, claim or encumbrance which would
           materially affect the use made and, to such Counsel's knowledge,
           proposed to be made, of any of the personal or real property of the
           Company and the Subsidiaries.

                 (xviii)  Nothing has come to the attention of Company Counsel
           that causes it to believe that each of the Company and the
           Subsidiaries does not have all licenses, permits, certifications,
           registrations, approvals, consents and franchises (collectively,
           "Permits") required to own or lease and operate its properties and to
           conduct its business as described in the Prospectus in all material
           respects or that there are any proceedings pending or threatened
           against the Company or any Subsidiary that may cause any such Permit
           that is material to the conduct of the business of the Company or any
           of the Subsidiaries as presently conducted to be revoked, withdrawn,
           canceled, suspended or not renewed.

                 (xix) The Common Shares have been approved for inclusion on the
           Nasdaq National Market.

           The foregoing opinion may be limited to the laws of the United States
     and the DGCL and Company Counsel may rely as to certain legal matters on
     other counsel to the Company provided that in each case, Company Counsel
     shall state that they believe that they and the Underwriters are justified
     in relying on such other counsel and shall deliver signed copies of any
     such opinion to the Representatives and as to questions of fact upon the
     representations of the Company set forth in this Agreement and upon
     certificates of officers of the Company and of government officials, all
     of which certificates must be reasonable and satisfactory in form and scope
     to counsel to the Underwriters provided that in each case, Company Counsel
     shall deliver signed copies of any such certificate to the Representatives.

           (g)   On the Closing Date and any Option Closing Date, there shall
     have been delivered to the Representatives a signed opinion of Blank Rome
     Comisky & McCauley, counsel to the Selling Stockholder, dated as of each
     such date and addressed to the Representatives, individually and as
     Representatives of the several Underwriters, in form and substance
     satisfactory to counsel to the Underwriters, to the effect that:

                 (i) The Selling Stockholder is an existing corporation in good
           standing under the laws of the State of Israel. The Selling
           Stockholder has full power and authority

                                      -34-
<PAGE>
 
           to own its assets and to conduct its business as described in the
           Prospectus and is duly qualified to do business in each jurisdiction
           in which it owns or leases real property or in which the conduct of
           its business requires such qualification.

                 (ii) This Agreement and the Agreement and Power of Attorney
           have been duly authorized, executed and delivered by or on behalf of
           the Selling Stockholder; to the best of such counsel's knowledge, the
           sale of the Shares to be sold by the Selling Stockholder at the
           Option Closing Date and the performance of this Agreement and the
           Agreement and Power of Attorney and the consummation of the
           transactions therein and herein contemplated will not, in any
           material respect, conflict with, or, with or without the giving of
           notice or the passage of time or both, result in a breach or
           violation of any of the terms or provisions of, or constitute a
           default under, any indenture, mortgage, deed of trust, loan
           agreement, lease or other agreement or instrument to which such
           Selling Stockholder is a party or to which any of its properties or
           assets is subject, nor will such action conflict with or violate any
           provision of the charter documents or Bylaws of the Selling
           Stockholder or any statute, rule or regulation or, to the best of
           such counsel's knowledge, any order, judgment or decree of any court
           or governmental agency or body having jurisdiction over the Selling
           Stockholder or any of the Selling Stockholder's properties or
           assets.

                 (iii)  No consent, approval, authorization, order or
           declaration of or from, or registration, qualification or filing
           with, any court or governmental agency or body is required for the
           issue and sale of the Shares being sold by the Selling Stockholder or
           the consummation of the transactions contemplated by this Agreement
           and the Agreement and Power of Attorney, except the registration of
           such Shares under the Act and such as may be required under the state
           securities or blue sky laws in connection with the offer, sale and
           distribution of such Shares by the Underwriters.

                 (iv) To the best of such counsel's knowledge, the Selling
           Stockholder has, and immediately prior to the Option Closing Date the
           Selling Stockholder will have, good and valid title to the Shares to
           be sold by the Selling Stockholder hereunder, free and clear of all
           liens, security interests, pledges, charges, encumbrances, defects,
           stockholders' agreements, voting trusts, equities or claims of any
           nature whatsoever; and, upon delivery of such Shares against payment
           therefor as provided herein, good and valid title to such Shares,
           free and clear of all liens, security interests, pledges, charges,
           encumbrances, defects, stockholders' agreements, voting trusts,
           equities or claims of any nature whatsoever, will pass to the several
           Underwriters.

                 (v) There are no transfer or similar taxes payable in
           connection with the sale and delivery of the Optional Shares by the
           Selling Stockholder to the Underwriters.

           In rendering such opinion, such counsel may relay as to certain legal
           matters on other legal counsel to the Selling Stockholder provided
           that, in each case, such counsel shall state that they believe that
           they and the Underwriters are justified in relying on such other
           counsel and shall deliver signed copies of any such opinion to the
           Representatives and, as to questions of fact, upon the
           representations of the Selling Stockholder set forth in this
           Agreement and upon certificates of officers of the Selling
           Stockholder and of government officials, all of which certificates
           must be reasonable and satisfactory in form and scope to counsel to
           the Underwriters provided that in each case, such counsel shall
           deliver signed copies of any such certificate to the Representatives.

           (h)   At the Closing Date and any Option Closing Date: (i) the
     Registration Statement and any post-effective amendment thereto and the
     Prospectus and any amendments or supplements thereto shall contain all
     statements that are required to be stated therein in accordance with the
     Act and the Regulations and in all material respects shall conform to the
     requirements of the Act and the Regulations, and neither the Registration
     Statement nor any post-effective amendment thereto nor the Prospectus and
     any amendments or supplements thereto shall contain any untrue statement of
     a material fact or omit to state any material fact required to be stated
     therein or necessary to make the statements therein, in light of the
     circumstances under which they were made, not misleading; (ii) since the
     respective dates as of which information is given in the Registration
     Statement and any post-effective amendment thereto and the Prospectus and
     any amendments or supplements thereto, except as otherwise stated therein,
     there shall have been no material adverse change in the properties,
     condition (financial or otherwise), results of operations, stockholders'
     equity, business or management of the Company and the Subsidiaries from
     that set forth therein, whether or not arising in the ordinary course of
     business, other than as referred to in the Registration Statement or the
     Prospectus; (iii) since the respective dates as of which information is
     given in the Registration Statement and the Prospectus or any amendment or
     supplement thereto, there shall have been no transaction, contract or
     agreement entered into by the Company or any Subsidiary, other than in the
     ordinary course of business and as set forth in the Registration Statement
     or the Prospectus, that has not been, but would be required to be, set
     forth in the Registration Statement or the Prospectus and (iv) no action,
     suit or proceeding at law or in equity shall be pending or, to the
     knowledge of the Company, threatened against the Company or any Subsidiary
     that would be required to be set forth in the Prospectus, other than as set
     forth therein, and no proceedings shall be pending or, to the knowledge of
     the Company, threatened against the Company or any Subsidiary before or by
     any federal, state or other commission, 

                                      -36-

     board or administrative agency wherein an unfavorable decision, ruling or
     finding would materially adversely affect the properties, condition
     (financial or otherwise), results of operations, stockholders' equity or
     business of the Company and the Subsidiaries other than as set forth in
     the Prospectus. The Representatives shall have received at the Closing
     Date certificates of the Chief Executive Officer and the Chief Financial
     Officer of the Company dated as of the date of the Closing Date or Option
     Closing Date, as the case may be, and certificates of the Chief Executive
     Officer and the Chief Financial Officer of the Selling Stockholder dated as
     of the date of any Option Closing Date, and addressed to the
     Representatives, individually and as the Representatives of the several
     Underwriters, to the effect, to the knowledge of such persons, that the
     conditions set forth in this subsection have been satisfied and as to the
     accuracy and performance, to the knowledge of such persons, as of the
     Closing Date or the Option Closing Date, as the case may be, of the
     agreements, representations and warranties of the Company set forth herein
     and as to the accuracy and performance to the knowledge of such persons, as
     of the Option Closing Date, the agreements, representations and warranties
     of the Selling Stockholder set forth herein.

           (i)   At the time this Agreement is executed and at the Closing Date
     and any Option Closing Date, the Representatives shall have received a
     letter addressed to the Representatives, individually and as the
     Representatives of the several Underwriters, and in form and substance
     satisfactory to the Representatives in all respects, including the non-
     material nature of the changes or decreases, if any, referred to in clause
     (iv) below, from Ernst & Young LLP dated as of the date of this Agreement,
     the Closing Date or any Option Closing Date, as the case may be:

                 (i) confirming that they are independent public accountants
           with respect to the Company and its consolidated subsidiaries within
           the meaning of the Act and the Regulations and stating that the
           section of the Registration Statement under the caption "Experts" is
           correct insofar as it relates to them;

                 (ii) stating that, in their opinion, the consolidated financial
           statements of the Company and the Subsidiaries (other than AEMI)
           audited by them and included in the Registration Statement and in the
           Prospectus comply in form in all material respects with the
           applicable accounting requirements of the Act and the Regulations;

                 (iii) the consolidated financial statements of the Company and
           the Subsidiaries (other than AEMI) as of and for the three-month
           period ended March 31, 1997, were reviewed by them in accordance with
           the standards established by the American Institute of Certified
           Public Accountants and based upon their review they are not aware of
           any material modifications that should be made to such 

                                      -37-
<PAGE>
 
     financial statements for them to be in conformity with generally accepted
     accounting principles, and such financial statements comply as to form in
     all material respects with the applicable accounting requirements of the
     Act and the Regulations thereunder;

           (iv) stating that, on the basis of specified procedures, not
     constituting an audit in accordance with generally accepted accounting
     principles, which included a reading of the unaudited interim consolidated
     financial statements of the Company and the Subsidiaries (other than AEMI)
     for period ended March 31, 1997, a reading of the minutes of the meetings
     of the stockholders and the Board of Directors of the Company and audit and
     compensation committees of such Board, if any, and inquiries to certain
     officers and other employees of the Company who are responsible for
     financial and accounting matters and other specified procedures and
     inquiries, nothing has come to their attention that would cause them to
     believe that (A) the unaudited consolidated financial statements and
     related schedules of the Company and the Subsidiaries included in the
     Registration Statement, if any (1) do not comply in form in all material
     respects with the applicable accounting requirements of the Act and the
     Regulations or (2) were not fairly presented in conformity with generally
     accepted accounting principles on a basis substantially consistent with
     that of the audited consolidated financial statements and related schedules
     included in the Registration Statement or (B)(1) at a specified date, not
     more than five business days prior to the date of such letter, there was
     more than a 10% change in the capital stock, inventories or short-term or
     long-term debt of the Company and the Subsidiaries or any decrease
     (increase) of more than 10% in net current assets, total assets or
     stockholders' equity compared with the amounts shown in the March 31, 1997
     consolidated balance sheet of the Company included in the Registration
     Statement, other than as set forth in or contemplated by the Registration
     Statement and the Prospectus, or if there was any such change or decrease
     (increase), setting forth the amount of such change or decrease 
     (increase), and (2) during the period from March 31, 1997 to a specified 
     date not more than five business days prior to the date of such letter,
     there has been any decrease of more than 10% in revenues or any increase of
     more than 10% in loss before interest income (expense), net and taxes or
     net loss of the Company and the Subsidiaries on a consolidated basis other
     than as set forth in or contemplated by the Registration Statement or the
     Prospectus; and

           (v) stating that they have compared specific dollar amounts,
     percentages, numbers of shares and other information (including pro forma
     information) pertaining to the Company and the Subsidiaries set forth in
     the Registration Statement and the Prospectus that have been specified by
     the Representatives prior to the date of this Agreement, to


                                     -38-
<PAGE>
 
     the extent that such amounts, percentages, numbers and information may be
     derived from the general accounting or other records of the Company and the
     Subsidiaries, with the results obtained from the application of specified
     readings, inquiries and other appropriate procedures, which procedures do
     not constitute an audit in accordance with generally accepted auditing
     standards, set forth in the letter, and found them to be in agreement.

           (vi) in the event that the letters referred to in this Section 7(i)
     set forth any changes, decreases or increases in the items specified in
     subsection (v) of this Section 7(i), it shall be a further condition to the
     obligations of the Underwriters that (A) such letters shall be accompanied
     by a written explanation by the Company as to the significance thereof,
     unless the Representatives deem such explanation unnecessary, and (B) such
     changes, decreases or increases do not, in their sole judgment, make it
     impractical or inadvisable to proceed with the purchase, sale and delivery
     of the Shares being delivered at the Closing Date or any Option Closing
     Date, as the case may be, as contemplated by the Registration Statement,
     as amended as of the date of such letter.

     (j)   At the time the Agreement is executed and at the Closing Date and any
Option Closing Date, the Representatives shall have received a letter addressed
to the Representatives individually and as the Representatives of the several
Underwriters, and in form and substance satisfactory to the Representatives in
all respects, from Messina, Ceci, Archer & Company, P.C. dated as of the date of
this Agreement, the Closing Date or any Option Closing Date, as the case may be:

           (i) confirming that they are independent public accountants with
     respect to Flam & Russell within the meaning of the Act and the Regulations
     and stating that the section of the Registration Statement under the
     caption "Experts" is correct insofar as it relates to them; and

           (ii) stating that, in their opinion, the financial statements of Flam
     & Russell audited by them and included in the Registration Statement and in
     the Prospectus comply in form in all material respects with the applicable
     accounting requirements of the Act and the Regulations.

     (k)   There shall have been duly tendered to the Representatives for the
respective accounts of the Underwriters certificates representing all of the
Shares to be purchased by the Underwriters on the Closing Date or any Option
Closing Date, as the case may be.

     (l)   At the Closing Date and any Option Closing Date, the Representatives
shall have been furnished such additional documents and certificates as they
shall reasonably request.


                                     -39-
<PAGE>
 
     (m)   No action shall have been taken by the NASD the effect of which is to
make it improper, at any time prior to the Closing Date or any Option Closing
Date, for members of the NASD to execute transactions as principal or as agent
in the Shares or to trade or deal in the Shares, and no proceedings for the
purpose of taking such action shall have been instituted or shall be pending or,
to the Company's or the Representatives' knowledge, shall be contemplated by the
NASD.

     If any condition to the Underwriters' obligations hereunder to be fulfilled
prior to or at the Closing Date or any Option Closing Date, as the case may be,
is not fulfilled, the Representatives may on behalf of the several Underwriters
terminate this Agreement or, if they so elect, waive any such conditions which
have not been fulfilled or extend the time for their fulfillment.

  8. Indemnification.

     (a) The Company and the Selling Stockholder, jointly and severally, shall
  indemnify and hold harmless each Underwriter, and each person, if any, who
  controls each Underwriter within the meaning of the Act or the Exchange Act,
  against any and all loss, liability, claim, damage and expense whatsoever,
  whether joint or several, to which such Underwriter may become subject, under
  the Act or otherwise, including, but not limited to, any and all expense
  whatsoever incurred in investigating, preparing or defending against any
  litigation, commenced or threatened, or any claim whatsoever or in connection
  with any investigation or inquiry of, or action or proceeding that may be
  brought against, the respective indemnified parties, arising out of or based
  upon any untrue statements or alleged untrue statements of a material fact
  contained in any Preliminary Prospectus, the Registration Statement or the
  Prospectus, or any application or other document (in this Section 8
  collectively called "application") executed by the Company and based upon
  written information furnished by or on behalf of the Company filed in any
  jurisdiction in order to qualify all or any part of the Shares under the
  securities laws thereof or filed with the SEC or the NASD, or the omission or
  alleged omission therefrom of a material fact required to be stated therein or
  necessary to make the statements therein, in light of the circumstances under
  which they were made, not misleading; provided, however, that the foregoing
  indemnity of the Company and the Selling Stockholder (i) shall not apply in
  respect of any statement or omission made in reliance upon and in conformity
  with written information furnished to the Company by any Underwriter through
  the Representatives expressly for use in any Preliminary Prospectus, the
  Registration Statement or the Prospectus, or any amendment thereto or
  supplement thereof, or in any application or in any communication to the SEC,
  as the case may be, (ii) with respect to any Preliminary Prospectus, shall not
  inure to the benefit of any Underwriter from whom the person asserting any
  such losses, claims, damages, liabilities or expenses purchased the Shares
  that are the subject thereof (or to the benefit of any person


                                     -40-
<PAGE>
 
     controlling such Underwriter) if at or prior to the written confirmation of
     the sale of such Shares a copy of an amended Preliminary Prospectus or the
     Prospectus (or the Prospectus as amended or supplemented) was not sent or
     delivered to such person and the untrue statement or omission of a material
     fact contained in such Preliminary Prospectus was corrected in the amended
     Preliminary Prospectus or Prospectus (or the Prospectus as amended or
     supplemented) and (iii) the Selling Stockholder's total liability under
     this Section 8 shall be limited to an amount equal to the purchase price
     received by the Selling Stockholder from the sale of the Optional Shares by
     it pursuant to this Agreement. Neither the Company nor the Selling Stock-
     holder will, without the prior written consent of the Underwriters, settle
     or compromise or consent to the entry of any judgment in any pending or
     threatened claim, action, suit or proceeding (or related cause of action
     or portion thereof) in respect of which indemnification may be sought
     hereunder, whether or not any Underwriter is a party to such claim, action,
     suit or proceeding, unless such settlement, compromise or consent includes
     an unconditional release of each Underwriter from all liability arising out
     of such claim, action, suit or proceeding (or related cause of action or
     portion thereof). This indemnity agreement will be in addition to any
     liability the Company or the Selling Stockholder may otherwise have.

           (b) Each Underwriter, severally and not jointly, shall indemnify and
     hold harmless the Company and the Selling Stockholder, each of the
     directors of the Company and the Selling Stockholder, each of the officers
     of the Company who shall have signed the Registration Statement and each
     other person, if any, who controls the Company or the Selling Stockholder
     within the meaning of the Act or the Exchange Act to the same extent as the
     foregoing indemnities from the Company and the Selling Stockholder to the
     several Underwriters, but only with respect to any loss, liability, claim,
     damage or expense resulting from statements or omissions, or alleged
     statements or omissions, if any, made in any Preliminary Prospectus, the
     Registration Statement or the Prospectus or any amendment thereto or
     supplement thereof or any application in reliance upon, and in conformity
     with written information furnished to the Company by any Underwriter
     through the Representatives with respect to any Underwriter by or on behalf
     of such Underwriter expressly for use in any Preliminary Prospectus, the
     Registration Statement or the Prospectus or any amendment thereto or
     supplement thereof or any application, as the case may be, or from the
     failure of any Underwriter at or prior to the written confirmation of the
     sale of Shares to send or deliver a copy of an amended Preliminary
     Prospectus or the Prospectus (or the Prospectus as amended or supplemented)
     to the person asserting any such losses, claims, damages, liabilities or
     expenses who purchased the Shares that are the subject thereof and the
     untrue statement or omission of a material fact contained in such
     Preliminary Prospectus was corrected in the amended Preliminary Prospectus
     or Prospectus (or the Prospectus as amended or supplemented). This
     indemnity


                                     -41-
<PAGE>
 
     agreement will be in addition to any liability which such Underwriter may
     otherwise have.

           (c) If any action, inquiry, investigation or proceeding is brought
     against any person in respect of which indemnity may be sought pursuant to
     any of the two preceding paragraphs, such person (hereinafter called the
     "indemnified party") shall, promptly after formal notification of, or
     receipt of service of process for, such action, inquiry, investigation or
     proceeding, notify in writing the party or parties against whom
     indemnification is to be sought (hereinafter called the "indemnifying
     party") of the institution of such action, inquiry, investigation or
     proceeding and the indemnifying party, upon the request of the indemnified
     party, shall assume the defense of such action, inquiry, investigation or
     proceeding, including the employment of counsel, reasonably satisfactory to
     such indemnified party, and payment of expenses. No indemnification
     provided for in this Section 8 shall be available to any indemnified party
     who shall fail to give such notice if the indemnifying party does not have
     knowledge of such action, inquiry, investigation or proceeding and shall
     have been materially prejudiced by the failure to give such notice, but the
     omission so to notify the indemnifying party shall not relieve the
     indemnifying party otherwise than under this Section 8. Such indemnified
     party or controlling person shall have the right to employ its or their own
     counsel in any such case, but the fees and expenses of such counsel shall
     be at the expense of such indemnified party unless the employment of such
     counsel shall have been authorized in writing by the indemnifying party in
     connection with the defense of such action or the indemnifying party shall
     not have employed counsel to have charge of the defense of such action,
     inquiry, investigation or proceeding or such indemnified party or parties
     shall have been advised by counsel that there is a conflict of interest
     that would prevent counsel to the indemnifying party from representing both
     parties, in any of which events the reasonable fees and expenses of such
     counsel shall be borne by the indemnifying party. It is understood that the
     indemnifying party shall not, in connection with any proceeding or related
     proceedings in the same jurisdiction, be liable for the fees and expenses
     of more than one separate counsel, in addition to one local counsel in each
     jurisdiction in which any proceeding may be brought, for all indemnified
     parties. In the case of any such separate counsel for the Underwriters,
     such firm shall be designated in writing by the Representatives. Expenses
     covered by the indemnification in this subsection (c) of this Section 8
     shall be paid by the indemnifying party as they are incurred by the
     indemnified party. Anything in this subsection to the contrary notwith-
     standing, the indemnifying party shall not be liable for any settlement of
     any such claim effected without its written consent. The indemnifying party
     shall promptly notify the indemnified party of the commencement of any
     litigation, inquiry, investigation or proceeding against the indemnifying
     party or any of its officers or directors in connection with the issue and
     sale of any of the Shares or in connection with such


                                     -42-
<PAGE>
 
     Preliminary Prospectus, Registration Statement or Prospectus, or any
     amendment thereto or supplement thereof or any such application.

           (d) If the indemnification provided for in this Section 8 is
     unavailable to or insufficient to hold harmless an indemnified party under
     subsections (a) or (b) of this Section 8 in respect of any losses,
     liabilities, claims, damages or expenses (or actions, inquiries,
     investigations or proceedings in respect thereof) referred to therein
     except either by reason of the proviso set forth in subsection (a) or the
     failure to give notice as required in subsection (c) (provided that the
     indemnifying party does not have knowledge of the action, inquiry,
     investigation or proceeding and has been materially prejudiced by the
     failure to give such notice), then each indemnifying party shall contribute
     to the amount paid or payable by such indemnified party as a result of such
     losses, liabilities, claims, damages or expenses (or actions, inquiries,
     investigations or proceedings in respect thereof) in such proportion as is
     appropriate to reflect the relative benefits received by the Company and
     the Selling Stockholder on the one hand and the Underwriters on the other
     from the offering of the Shares. If, however, the allocation provided by
     the immediately preceding sentence is not permitted by applicable law or
     the indemnified party failed to give the notice required under subsection
     (c) then each indemnifying party shall contribute to such amount paid or
     payable by such indemnified party in such proportion as is appropriate to
     reflect not only such relative benefits but also the relative fault of the
     Company and the Selling Stockholder on the one hand and the Underwriters
     on the other in connection with the statements or omissions which resulted
     in such losses, liabilities, claims or reasonable expenses (or actions,
     inquiries, investigations or proceedings in respect thereof), as well as
     any other relevant equitable considerations. The relative benefits
     received by the Company and the Selling Stockholders on the one hand and
     the Underwriters on the other shall be deemed to be in the same proportion
     as the total net proceeds from the offering (before deducting expenses)
     received by the Company and the Selling Stockholder bear to the total
     underwriting discounts and commissions received by the Underwriters, in
     each case as set forth in the table on the cover page of the Prospectus.
     The relative fault shall be determined by reference to, among other things,
     whether the untrue or alleged untrue statement of a material fact or the
     omission or alleged omission to state a material fact relates to
     information supplied by the Company and the Selling Stockholder on the one
     hand or the Underwriters on the other hand and the parties' relative
     intent, knowledge, access to information and opportunity to correct or
     prevent such statement or omission. The Company, the Selling Stockholder
     and the Underwriters agree that it would not be just and equitable if
     contributions pursuant to this subsection (d) were determined by pro rata
     allocation (even if the Underwriters were treated as one entity for such
     purpose) or by any other method of allocation that does not take account of
     the equitable considerations referred to above


                                     -43-
<PAGE>
 
     in this subsection (d). The amount paid or payable by an indemnified party
     as a result of the losses, liabilities, claims, damages or reasonable
     expenses (or actions, inquiries, investigations or proceedings in respect
     thereof) referred to above in this subsection (d) shall be deemed to
     include any legal or other expenses reasonably incurred by such indemnified
     party in connection with investigating or defending any such action or
     claim. Notwithstanding the provisions of this subsection (d), no
     Underwriter shall be required to contribute any amount in excess of the
     amount by which the total price at which the Shares underwritten by it and
     distributed to the public exceeds the amount of any damages which such
     Underwriter has otherwise been required to pay by reason of such untrue or
     alleged untrue statement or omission or alleged omission. No person guilty
     of fraudulent misrepresentation (within the meaning of Section 11(f) of the
     Act) shall be entitled to contribution from any person who was not guilty
     of such fraudulent misrepresentation. The Underwriters' obligations in
     this subsection (d) to contribute are several in proportion to their
     respective underwriting obligations and not joint.

     9.   Representations and Agreements to Survive Delivery.  Except as the
context otherwise requires, all representations, warranties and agreements
contained in this Agreement shall be deemed to be representations, warranties
and agreements at the Closing Date and any Option Closing Date; and such
representations, warranties and agreements of the Underwriter, the Company and
the Selling Stockholder, including without limitation the indemnity and
contribution agreements contained in Section 8 hereof and the agreements
contained in Sections 6, 9, 10 and 13 hereof, shall remain operative and in full
force and effect regardless of any investigation made by or on behalf of any
Underwriter or any controlling person thereof, and shall survive delivery of the
Shares and termination of this Agreement, whether before or after the Closing
Date or any Option Closing Date.  With respect to any obligation of the Company
and the Selling Stockholder hereunder to make any payment, to indemnify for any
liability or to reimburse for any expense, notwithstanding the fact that such
obligation is a joint and several obligation of the Company and the Selling
Stockholder, the Underwriters, or any other person to whom such payment,
indemnification or reimbursement is owed, may pursue the Company with respect
thereto prior to pursuing the Selling Stockholder.

     10.   Effective Date of this Agreement and Termination Thereof.

           (a) This Agreement shall become effective immediately as to Sections
     6, 8, 9, 10 and 13 and, as to all other provisions, (i) if at the time of
     execution and delivery of this Agreement the Registration Statement has not
     become effective, at 11:00 a.m., Philadelphia time, on the first business

     Statement and the Prospectus, any material adverse change or any
     development involving a prospective material adverse change in or affecting

     or the earnings, business affairs, management or business prospects of the
     Company and the Subsidiaries, whether or not arising in the ordinary course
     of business; (ii) any outbreak of hostilities or other national or
     international calamity or crisis or change in economic, political or
     financial market conditions if such outbreak, calamity, crisis or change

     effect on the Company, the financial markets of the United States or the
     offering or delivery of the Shares; (iii) suspension of trading generally
     in securities on the New York Stock Exchange, the American Stock Exchange
     or the over-the-counter market or limitation on prices (other than

     promulgation of any federal or state statute, regulation, rule or order of
     any court or other governmental authority which in the Representatives'
     reasonable opinion materially and adversely affects trading on such
     Exchange or the over-the-counter market; (iv) the enactment, publication,
     decree or other promulgation of any federal or state statute, regulation,
     rule or order of any court or other governmental authority which in the
     Representatives' reasonable opinion materially and adversely affects or
     will materially or adversely affect the business or operations of the
     Company and the Subsidiaries; (v) declaration of a banking moratorium by
     either federal or state authorities; (vi) the taking of any action by any

                                     -45-
<PAGE>
 
     any securities of the Company shall have been suspended or halted by the
     NASD or the SEC.

           (c) If the Representatives elect to prevent this Agreement from
     becoming effective or to terminate this Agreement as provided in this
     Section 10, the Representatives shall notify the Company and the Selling
     Stockholder thereof promptly by telephone, telex, telegraph, telegram or
     facsimile, confirmed by letter.

     11.   Default by an Underwriter.

           (a) If any Underwriter or Underwriters shall default in its or their
     obligation to purchase Offered Shares or Optional Shares hereunder, and if
     the Offered Shares or Optional Shares with respect to which such default
     relates do not exceed the aggregate of 10% of the number of Offered Shares
     or Optional Shares, as the case may be, that all Underwriters have agreed
     to purchase hereunder, then such Offered Shares or Optional Shares to which
     the default relates shall be purchased severally by the non-defaulting
     Underwriters in proportion to their respective commitments hereunder.

           (b) If such default relates to more than 10% of the Offered Shares or
     the Optional Shares, as the case may be, the Representatives may in their
     discretion arrange for another party or parties (including a non-defaulting
     Underwriter) to purchase such Offered Shares or Optional Shares to which
     such default relates, on the terms contained herein. In the event that the
     Representatives do not arrange for the purchase of the Offered Shares or
     the Optional Shares to which a default relates as provided in this Section
     11, this Agreement may be terminated by the Representatives or by the
     Company, in the case of the Offered Shares, or by the Representatives or by
     the Selling Stockholder, in the case of the Optional Shares, without
     liability on the part of the several Underwriters (except as provided in
     Section 8 hereof) or the Company or the Selling Stockholder (except as
     provided in Sections 6 and 8 hereof), but nothing herein shall relieve a
     defaulting Underwriter of its liability, if any, to the other several
     Underwriters and to the Company or the Selling Stockholder for damages
     occasioned by its default hereunder.

           (c) If the Offered Shares or Optional Shares to which the default
     relates are to be purchased by the non-defaulting Underwriters, or are to
     be purchased by another party or parties as aforesaid, the Representatives
     or the Company shall have the right to postpone the Closing Date or the
     Representatives or the Selling Stockholder shall have the right to postpone
     any Option Closing Date, as the case may be, for a reasonable period but
     not in any event exceeding seven days, in order to effect whatever changes
     may thereby be made necessary in the Registration Statement or the
     Prospectus or in any other documents and arrangements, and the Company
     agrees to file promptly any amendment to the Registration Statement or
     supplement to the

                               CUSTODY AGREEMENT


     CUSTODY AGREEMENT, dated ________________, 1997, among ___________________,
as Custodian (the "Custodian"), and Orbit-Alchut Technologies, Ltd. (the 
"Selling Stockholder").

     Orbit/FR, Inc., a Delaware corporation (the "Company"), has filed a 
registration statement (together with any subsequent registration statement 
filed pursuant to Rule 462(b) under the Securities Act of 1933, as amended (the 
"Act") relating to the prior registration statement, the "Registration 
Statement") with the Securities and Exchange Commission to register for sale to 
the public under the Act, shares of the Company's Common Stock, par value $.01 
per share (the "Common Shares").

     The shares to be covered by the Registration Statement shall consist of 
(a) up to 2,000,000 Common Shares to be sold by the Company and (b) up to 
300,000 Common Shares (the "Shares") to be sold by the Selling Stockholder.

     The Selling Stockholder has executed and delivered a Power of Attorney (the
"Power of Attorney") naming _______________________ and _______________________,
and each of them, as its attorney-in-fact (the "Committee"), for certain 
purposes, including the execution, delivery and performance of this Agreement in
its name, place and stead, in connection with the proposed sale by the Selling 
Stockholder of the Shares.

     1.   A custody arrangement is hereby established by the Selling 
Stockholder with the Custodian with respect to the Shares, and the Custodian is 
hereby instructed to act in accordance with the Agreement and any amendments or 
supplements hereto authorized by the Committee.

     2.   There are herewith delivered to the Custodian, and the Custodian 
hereby acknowledges receipt of, certificates representing the Shares, which 
certificates have been endorsed in blank or are accompanied by duly executed 
stock powers, in each case with all signatures accompanied by the signature of 
another officer of the Selling Stockholder.  Such certificates are to be held by
the Custodian for the account of the Selling Stockholder and are to be disposed 
of by the Custodian in accordance with this Agreement.

     3.   The Custodian is authorized and directed by the Selling Stockholder:

          (a)   To hold the certificates representing the Shares delivered by 
the Selling Stockholder in the Custodian's custody;

          (b)   On or prior to any closing date for any Shares sold pursuant to 
the Registration Statement (an "Option Closing Date"), to cause such Shares to 
be transferred on the books of

                                      B-7
<PAGE>
 
     the Company into such names as the Custodian shall have been instructed by
     the representatives (the "Representatives") of the several Underwriters
     (the "Underwriters"); to cause to be issued, against surrender of the
     certificates for the Shares, a new certificate or certificates for such
     Shares, free of any restrictive legend, registered in such name or names;
     to deliver such new certificates in such name or names, to deliver such new
     certificates representing such Shares to the Representatives, as instructed
     by the Representatives on the Option Closing Date for their account or
     accounts against full payment therefor and to give receipt for such
     payment; and

          (c)  To disburse such payments in the following manner: (i) to itself,
     as agent for the Selling Stockholder, a reserve amount to be designated in
     writing by the Committee from which amount the Custodian shall pay, as soon
     as reasonably practicable, any applicable stock transfer taxes and (ii) to
     the Selling Stockholder, pursuant to the written instructions of the
     Committee, (A) on the Option Closing Date, a sum equal to the proceeds to
     which the Selling Stockholder is entitled, as determined by the Committee,
     less the reserve amount designated by the Committee and (B) promptly after
     all proper charges, disbursements, costs and expenses shall have been paid,
     any remaining balance of the amount reserved under clause (i) above. Before
     making any payment from the amount reserved under clause (i) above, except
     payments made pursuant to subclause (B) of clause (ii) above, the Custodian
     shall request and receive the written approval of the Committee.

     4.   Subject in each case to the indemnification obligations set forth in 
Section 7, in the event Shares of the Selling Stockholder are not sold prior to 
August 31, 1997, the Custodian shall deliver to the Selling Stockholder as soon 
as practicable after the earlier to occur of such date and termination of the 
offering of the Shares, certificates representing such Shares deposited by the 
Selling Stockholder. Certificates returned to the Selling Stockholder shall be 
returned with any related stock powers, and any new certificates issued to the 
Selling Stockholder with respect to such Shares shall bear any appropriate 
legend reflecting the unregistered status thereof under the Act.

     5.   This Agreement is for the express benefit of the Company and the 
Selling Stockholder, the Underwriters and the Representatives. The obligations 
and authorizations of the Selling Stockholder hereunder are irrevocable and 
shall not be terminated by any act of the Selling Stockholder or by operation of
law, whether by the incapacity of the Selling Stockholder or by the occurrence
of any other event or events, and if after the execution hereof the Selling
Stockholder shall be incapacitated, or if any other event or events shall occur
before the delivery of the Selling Stockholder's Shares hereunder to the
Representatives, such Shares shall be delivered to the Representatives in
accordance with the terms and conditions of this Agreement, as if such event had
not occurred, regardless of whether or not the Custodian shall have received
notice of such event.

     6.    Until payment of the purchase price for the Shares has been made to 
the Selling Stockholder or to the Custodian, the Selling Stockholder shall 
remain the owner of, and shall retain the right to receive dividends and 
distributions on, and to vote, the number of Shares delivered by it to the 
Custodian hereunder.  Until such payment in full has been made or until the 
offering of Shares has been terminated, the Selling Stockholder agrees that it 
will not give, assign, sell, agree to sell, pledge, hypothecate, grant any lien 
on, transfer, or otherwise dispose of the Shares or any interests therein.

to deal with the certificates for the Shares and the proceeds from the sale of 
the Shares represented thereby in accordance with the provisions hereof, and 
the Selling Stockholder hereby agrees to indemnify the Custodian for and to 
hold the Custodian harmless against any and all losses, claims, damages or 
liabilities incurred on its part arising out or in connection with it acting as 
the Custodian pursuant hereto, as well as the costs and expenses of 
investigating and defending any such losses, claims, damages or liabilities, 
except to the extent such losses, claims, damages or liabilities are due to the 
negligence or bad faith of the Custodian; provided that the maximum amount for 
which the Selling Stockholder shall be liable under this Agreement shall be the 
net proceeds from the offering received by the Selling Stockholder less any 
amounts for which the Selling Stockholder is liable for indemnification under 
Section 8 of the Underwriting Agreement and Section 6 of the Agreement and Power
of Attorney.  The Selling Stockholder agrees that the Custodian may consult with
counsel of its own choice, who may be counsel for the Company, and the Custodian
shall have full and complete authorization and protection for any action taken 
or suffered by the Custodian hereunder in good faith and in accordance with the 
opinion of such counsel.

     8.    The Selling Stockholder hereby represents and warrants that:  (a) it
has, and at the time of delivery of its Shares to the Representatives it will 
have, full power and authority to enter into this Agreement and the Power of 
Attorney, to carry out the terms and provisions hereof and thereof and to make 
all of the representations, warranties and agreements contained herein and 
therein and (b) this Agreement and the Power of Attorney are the valid and 
binding agreements of the Selling Stockholder and are enforceable against the 
Selling Stockholder in accordance with their respective terms.

     9.    The Custodian's acceptance of this Agreement by the Custodian's 
execution hereof shall constitute an acknowledgment by the Custodian of the 
authorization herein conferred and shall evidence the Custodian's agreement to 
carry out and perform this Agreement in accordance with its terms.

     10.   The Custodian shall be entitled to act and rely upon any statement,

     11. This Agreement may be executed in two or more counterparts with the 
same effect as if the signatures thereto and hereto were upon the same 
instrument. Execution by the Custodian of one counterpart hereof and its 
delivery thereof to the Committee shall constitute the valid execution of this 
Agreement by the Custodian.

     12. This Agreement shall be binding upon the Custodian, the Selling 
Stockholder and the respective, legal representatives, distributees, successors 
and assigns of the Selling Stockholder.

     13. This Agreement shall be governed by the laws of the Commonwealth of

long as, it is coupled with an interest sufficient in law to support an
irrevocable power.  A proxy may be made irrevocable regardless of whether the
interest with which it is coupled is an interest in the stock itself or an
interest in the corporation generally.  All proxies shall be filed with the
Secretary of the meeting before being voted upon.

reasonable cause to believe his conduct was unlawful.  Indemnification as
provided by this Section shall be made by the corporation only as authorized in
the specific case, and only upon a determination that the person claiming

the stockholders entitled to notice of or to vote at any meeting of
stockholders, or to receive payment of any dividend or other distribution or
allotment of any rights or to exercise any rights in respect of any change,
conversion or exchange of stock or for the purpose of any other lawful action,
the Board of Directors may fix a record date, which record date shall not
precede the date on which the resolution fixing the record date is adopted and
which record date shall not be more than sixty nor less than ten days before the
date of any meeting of stockholders, nor more than sixty days prior to the time
for such other action as hereinbefore described; provided, however, that if no
record date is fixed by the Board of Directors, the record date for determining
stockholders entitled to notice of or to vote at a meeting of stockholders shall
be at the close of business on the day next preceding the day on which notice is
given or, if notice is waived, at the close of business on the day next
preceding the day on which the meeting is held, and, for determining
stockholders entitled to receive payment of any dividend or other distribution
or allotment of rights or to exercise any rights of change, conversion or

relating thereto.  A determination of stockholders of record entitled to notice

the date upon which the resolution fixing the record date is adopted by the
Board of Directors, and which record date shall be not more than ten days after

record date has been fixed by the Board of Directors and no prior action by the
Board of Directors is required by the Delaware General Corporation Law, the
record date shall be the first date on which a signed written consent setting
forth the action taken or proposed to be taken is delivered to the corporation
in the manner prescribed by Article III, Section 8 hereof. If no record date has
been fixed by the Board of Directors and prior action by the Board of Directors
is required by the Delaware General Corporation Law with respect to the proposed
action by written consent of the stockholders, the record date for determining
stockholders entitled to consent to corporate action in writing shall be at the
close of business on the day on which the Board of Directors adopts the
resolution taking such prior action.

           Registration Statement on Form S-1
           File No. 333-25015
           ------------------

Gentlemen:

     We have acted as counsel to ORBIT/FR, Inc. (the "Company") in connection
with the preparation of the Registration Statement on Form S-1, as amended
("Registration Statement") filed by the Company with the Securities and Exchange
Commission under the Securities Act of 1933, as amended, relating to the offer
and sale (i) by the Company of up to 2,000,000 shares (the "Firm Shares") of its
common stock, par value $.01 per share ("Common Stock"), and (ii) by a selling
stockholder of up to 300,000 shares of Common Stock to be purchased at the
option of the Underwriters to cover over-allotments, if any (the "Option
Shares").

     Although as counsel to the Company we have advised the Company in
connection with a variety of matters referred to us by it, our services are
limited to specific matters so referred. Consequently, we may not have knowledge
of many transactions in which the Company engaged or its day-to-day operations.

     In rendering this opinion, we have examined only the following documents:
(i) the Company's Certificate of Incorporation and Bylaws, as amended and
restated since the inception of the Company; (ii) resolutions adopted by the
Company's Board of Directors and its sole stockholder as contained in the
Company's minute books; and (iii) the Registration Statement.
 
     We have not made any independent investigation in rendering this opinion
other than the document examination described above.  Our opinion is therefore
qualified in all respects by the scope of that document examination.  We make no
representation as to the sufficiency of our
<PAGE>

investigation for your purposes.  We have assumed and relied on the truth,
completeness, authenticity and due authorization of all documents and records
examined and the genuineness of all signatures.  This opinion is limited to the
Delaware General Corporation Law.  In rendering this opinion, we have assumed
compliance with all other laws, including federal laws.

     Based upon and subject to the limitations stated herein, we are of the
opinion that (i) the Firm Shares which are being offered and sold by the Company
pursuant to the Registration Statement, when sold in the manner and for the
consideration contemplated by the Registration Statement, will be legally
issued, fully paid and non-assessable, and (ii) the Option Shares are legally
issued, fully paid and non-assessable.

     This opinion is given as of the date hereof.  We assume no obligation to
update or supplement this opinion to reflect any facts or circumstances which
may hereafter come to our attention or any changes in laws which may hereafter
occur.

     We consent to the filing of this opinion as an exhibit to the Registration
Statement and to the reference to us under the caption "Legal Matters" in the
Prospectus that is a part of the Registration Statement.

                                 Sincerely,

                                 /s/ Blank Rome Comisky & McCauley
