Stock at an exercise price of $9.847 per share. The Warrant exercise price and
the number of shares issuable upon exercise of the Warrants are subject to
adjustment under certain circumstances. The Company may redeem outstanding
Warrants commencing six months after the date of this Prospectus on not less
than 30 days' notice at a price of $.25 per Warrant (subject to adjustment under
certain circumstances) if the closing bid price of the Common Stock averages in
excess of 200% of the exercise price for a period of 30 days ending within 15
days of the redemption notice date. The Shares and the Warrants may only be
purchased together, but will be separately transferable immediately following
the completion of the Offering.
    
 
   
     The Common Stock is traded on The NASDAQ SmallCap Market under the symbol
"BARR." The Common Stock and the Warrants have been approved for inclusion in
The NASDAQ National Market System ("NMS"). On November 11, 1996, the closing
sale price of the Common Stock as reported by NASDAQ was $8.875 per share. See

and "Underwriting." Unless the context otherwise requires, all references in
this Prospectus to the Company refer to Barringer Technologies Inc. and its
subsidiaries.
 
                                  THE COMPANY
 
     Barringer Technologies Inc. (the "Company") is principally engaged in the
design, development, manufacture and sale of analytical instruments used for the
high sensitivity detection of trace amounts of plastic and other explosives and
illegal narcotics. The Company's principal product, the IONSCAN(R), is a
portable, desk-top instrument that utilizes a proprietary implementation of ion
mobility spectrometry ("IMS") technology to determine the presence or absence of
targeted compounds in a sample. The IONSCAN(R) can detect targeted substances in
amounts smaller than one-billionth of a gram in approximately six seconds. See
"Business -- IONSCAN(R) Technology."
 
   
     The Company's customers are primarily governmental, security and law
enforcement agencies throughout the world, including the Federal Bureau of
Investigation (the "FBI"), the Drug Enforcement Agency (the "DEA"), the General
Services Administration (the "GSA"), the United States, French, and Canadian
customs services and various airports worldwide. Because of its high
sensitivity, the IONSCAN(R) is used both in lieu of and in conjunction with
other detection technologies, such as X-ray, computer aided tomography
("CATSCAN"), quadropole resonance and nuclear magnetic resonance imaging. As of
September 30, 1996, the Company had sold over 325 IONSCAN(R)s, and the Company
believes that, in terms of units sold, it is the world's leading supplier of
trace particle detection instruments. See "Business -- Overview."
    
 
     IONSCAN(R)s have been sold for explosives detection applications primarily
outside the United States and for drug interdiction and detection both within
the United States and elsewhere. For example, the IONSCAN(R) is used in foreign
airports, on trains and at the Eurotunnel to check for explosives and by the
United States Coast Guard to check ships and cargo in U.S. territorial waters
for illegal narcotics. The Company believes that the security-related market for
the IONSCAN(R) is growing as a result of governmental actions, particularly in
the United States, which reflect heightened public safety concerns in the wake
of an increasing number of terrorist acts. Recently, Congress appropriated
$144,000,000 for the purchase of enhanced explosives detection equipment for use
at certain airports in the United States, and the Company believes that a
portion of such appropriation will be utilized for the acquisition of trace
particle detection equipment. The Company also believes that additional growth
will occur in the drug interdiction market for the IONSCAN(R) as a result of
recently reported increases in domestic drug usage, particularly among
teenagers. However, no assurance can be given as to the growth of either the
security-related market or the drug interdiction market for the IONSCAN(R).
 
     The Company's objective is to strengthen its position as the leading
supplier of trace detection equipment by (i) further penetrating existing
markets for the IONSCAN(R) through aggressive pursuit of additional sales, (ii)
expanding the uses of the IONSCAN(R), particularly for security screening of
individuals and for process control and quality assurance in certain industrial
applications, and (iii) extending the capabilities and the potential uses of the
IONSCAN(R) for environmental, biological and chemical testing by, among other
things, combining the IMS technology used by the IONSCAN(R) with other existing
technologies, such as gas chromatography, and by developing a hand-held detector
utilizing the IONSCAN(R) technology. See "Business -- Strategy."
 
     The Company believes that it is well positioned to implement its strategy
as a result of the large installed base of IONSCAN(R)s, the IONSCAN(R)'s
favorable field performance, its low price as compared to other available
detection equipment and its ease of use.

                                  RISK FACTORS
 
     In addition to the other information contained in this Prospectus, the
following risk factors should be considered carefully in evaluating an
investment in the Securities offered hereby.
 
HISTORY OF LOSSES
 
   
     The Company sustained net losses of $2,565,000 and $827,000 for the years
ended December 31, 1994 and 1995, respectively, and had an accumulated deficit
of $15,458,000 at September 30, 1996. Although the Company generated net income
of $1,108,000 for the first nine months of 1996, there can be no assurance that
the Company will be able to sustain a profitable level of operations in any
future period.
    
 
CASH CONSTRAINTS
 
     Historically, the Company has not generated net cash flow from operations
and, accordingly, has experienced periodic severe cash shortages. Although the
Company will seek to improve its cash flow through, among other things, the use
of a portion of the proceeds of this Offering and the implementation of its
business strategy, no assurance can be given that the Company will have
sufficient cash to implement such strategy or that implementation of such
strategy will enable the Company to satisfy its long-term cash requirements. See
"Business -- Strategy."
 
DEPENDENCE ON AND EFFECTS OF GOVERNMENTAL REGULATION
 
     The Company's business is dependent upon purchases of IONSCAN(R)s by
governmental agencies. See "Government and Other Procurement Policies." While
the Company believes that certain of its governmental customers will continue to
purchase IONSCAN(R)s for explosives detection and drug interdiction
applications, growth in the Company's business will be driven in part by the
adoption of regulations or requirements in the aviation security market
resulting in the use of enhanced explosives detection systems, including trace
particle detection equipment. As a result of certain government initiatives in
the United States, including the recent report of the Aviation Safety and
Security Commission (the "Gore Commission"), the Company anticipates that such
regulations or requirements will be adopted in the United States in the near
future. Among other things, the initial Gore Commission report recommended that
the government purchase enhanced explosives detection equipment for deployment
at certain United States airports. In October 1996, Congress appropriated
approximately $1.1 billion to fund certain anti-terrorist programs in fiscal
1997, including the initial recommendations contained in the Gore Commission
report. It is anticipated that approximately $144,000,000 of such appropriation
will be used to purchase enhanced explosives detection equipment. There can be
no assurance that funding for the purchase of such equipment will be continued
in subsequent fiscal years or as to the level thereof. While the recent
government initiatives have contemplated the deployment of trace particle
detection equipment, such as the IONSCAN(R), a substantial amount of the
appropriated funds will be used to purchase equipment utilizing other
technologies, such as CATSCAN, enhanced X-ray, quadropole resonance and other
imaging techniques. Accordingly, there can be no assurance as to the amount that
will ultimately be spent on the purchase of trace particle detection equipment
or as to the number of IONSCAN(R)s that will actually be purchased. In addition,
there can be no assurance that the IONSCAN(R) will meet any certification or
other requirements that may be adopted in connection with such initiatives.
 
     The Company anticipates that the aviation security market will undergo
significant technological changes in the future. As part of its oversight of the
domestic aviation industry, the Federal Aviation Administration (the "FAA")
sponsors research in the area of enhanced explosives detection technologies.
During the last five years, the FAA has spent approximately $150,000,000 on such
research and development activities. The FAA's sponsorship covers a wide range
of areas, such as imaging technologies, individual passenger screening systems,
development of bomb-resistant containers and trace detection methods including
those developed by the Company as well as by other entities. The Gore Commission
recommended dramatically increasing the amount spent on research and development
of enhanced explosives detection technologies and Congress recently increased
the FAA's budget for such research and development activities in fiscal 1997. As
a result of these initiatives, the Company anticipates that new technology will
be introduced into the aviation security
 
                                        7
<PAGE>   9
 
market in the future. While the Company believes that its IONSCAN(R) functions
at a state-of-the-art level, there can be no assurance that the Company will be
able to maintain its present position in this market. See "Dependence on New
Product Development; Technological Advancement."
 
GOVERNMENT AND OTHER PROCUREMENT POLICIES
 
     The Company's principal customers are governmental agencies and law
enforcement entities that are subject to budgetary processes and expenditure
constraints. Budgetary allocations for detection equipment are dependent, in
part, upon governmental policies which fluctuate from time to time in response
to political and other factors. A reduction of funding for drug interdiction and
security efforts could materially and adversely affect the Company's business,
financial condition and results of operations.
 
     Moreover, although the Company's sales are not seasonal in nature,
governmental agencies and certain of the Company's other customers expend unused
budgeted funds at the end of their respective fiscal years, causing the
Company's sales to be higher during such periods. Since the Company recognizes
substantially all of the revenue from a sale upon shipment, and since the
recognition of revenue from the sale of relatively few IONSCAN(R)s may
substantially impact the Company's profitability during any period, the impact
of these budgetary considerations on the delivery date of a relatively few units
could significantly affect the Company's quarterly results.
 
DEPENDENCE ON IONSCAN(R) AND MARKET ACCEPTANCE
 
     The Company's future profitability is substantially dependent on the
Company's ability to successfully market the IONSCAN(R). While the Company
believes that significant markets exist for its IONSCAN(R) technology, there can
be no assurance that such markets will develop as the Company expects or that
the Company will be able to capitalize on such market development. Similarly,
there can be no assurance that any markets that do develop will be sustained.
 
DEPENDENCE ON NEW PRODUCT DEVELOPMENT; TECHNOLOGICAL ADVANCEMENT
 
     The Company's success is dependent upon its ability to continue to enhance
the IONSCAN(R) and to develop and introduce in a timely manner new IONSCAN(R)
products that incorporate technological advances, keep pace with evolving
industry standards and respond to customer requirements. There can be no
assurance that the Company will be successful in developing and marketing
enhancements to the IONSCAN(R) or new IONSCAN(R) products on a timely basis or
that any new or enhanced IONSCAN(R) products will adequately address the
changing needs or preferences of the marketplace. If the Company is unable to
develop and introduce new products or enhancements in a timely manner in
response to changing market conditions or customer requirements, the Company's
business and operating results would be materially adversely affected.
 
     In addition, from time to time the Company or its present or potential
competitors may announce new products, capabilities or technologies that have
the potential to replace or shorten the life spans of the Company's existing
products. Announcements of currently planned or other new products may cause
customers to delay their purchasing decisions in anticipation of such products,
as occurred in late 1994 when the Company introduced the Model 400 IONSCAN(R).
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations." Such delays could have a material adverse effect on the Company's
business, results of operations and financial condition.
 
LACK OF PROPRIETARY TECHNOLOGY
 
     The Company believes that its implementation of IMS technology in the
IONSCAN(R) is proprietary to the Company. The Company has an exclusive license
from the Canadian government for certain technology used in the IONSCAN(R). See
"Business -- Patents, Trademarks and Proprietary Rights." In addition, the
Company has a number of patents covering certain aspects of the IONSCAN(R).
However, the basic IMS technology is not proprietary and is available in the
public domain. Accordingly, present and potential competitors could use such
technology to duplicate the performance of the IONSCAN(R). However, the
 
                                        8
<PAGE>   10
 
Company believes that such competitors could not readily replicate the
IONSCAN(R)'s performance and that any attempt to do so would require substantial
time and resources.
 
COMPETITION
 
     The Company competes with other entities, a number of which have
significantly greater financial, marketing and other resources than the Company.
In particular, the Company competes for governmental expenditures with equipment
manufacturers utilizing other types of detection technologies, including
CATSCAN, enhanced X-ray and quadropole resonance, as well as with manufacturers
of other IMS equipment and manufacturers using other trace particle detection
technologies, such as gas chromatography and chemoluminescence. As a result of
recent governmental initiatives, the Company anticipates that additional
technologies, including improved IMS technologies, will be developed and that
new competitors will enter the Company's markets. See "Dependence on and Effect
of Governmental Regulation." While the Company believes that it competes
effectively in its principal markets, there can be no assurance that the Company
will maintain its competitive position.
 
NONCOMPLIANCE UNDER CREDIT FACILITY
 
     The Company's principal subsidiary, Barringer Research Ltd. ("BRL"), is a
party to a credit facility (the "Facility") with the Toronto-Dominion Bank (the
"Bank") which the Company intends to repay in full with a portion of the net
proceeds of the Offering. See "Use of Proceeds." From time to time, BRL has not
been in compliance with the terms of the Facility. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."
 
RETENTION OF AND DEPENDENCE ON KEY PERSONNEL
 
   
     The Company's success will depend, in part, on its ability to retain the
services of its key personnel, including management and scientific employees,
who are and will continue to be instrumental in the development and management
of the Company's business. Although the Company has entered into employment
agreements with its Chief Executive Officer and certain of its other senior
executives, the loss of the services of one or more of the Company's key
employees could have a material adverse effect on the Company.
    
 
WARRANTY CLAIMS
 
     The Company generally provides a one-year parts and labor warranty on each
IONSCAN(R). Although the Company has not experienced significant warranty
claims, there can be no assurance that such claims will not increase as the
Company's sales increase. A material increase in warranty claims could have a
material adverse effect on the Company's business, results of operations and
financial condition.
 
POTENTIAL PRODUCT LIABILITY INSURANCE LIMITS
 
     The Company currently maintains product liability insurance in the amount
of $5 million per occurrence. The Company's insurance policy covers certain
claims and the cost of legal fees involved in the defense of such claims, which
are either covered under the policy or alleged in such a manner so as to invoke
the insurer's duty to defend the Company. No significant product liability
claims have been asserted or, to the knowledge of the Company's management,
threatened against the Company to date. The Company believes that, as the
Company distributes more products into the marketplace and expands its product
lines, the Company's exposure to potential product liability claims and
litigation arising from injuries and other damages allegedly caused by the
improper functioning or design of its IONSCAN(R) products will occur and may
increase. There can be no assurance that the Company's current level of
insurance will be sufficient to protect the business and assets of the Company
from all claims, nor can any assurance be given that the Company will be able to
maintain the existing coverage or additional coverage at commercially reasonable
rates. To the extent product liability losses are beyond the limits or scope of
the Company's insurance coverage, the Company could experience a materially
adverse effect on its business, results of operations and financial condition.
 
                                        9
<PAGE>   11
 
CURRENCY FLUCTUATIONS
 
     A portion of the Company's revenues and expenses are denominated in foreign
currencies. As a result, the Company is exposed to a certain degree of exchange
rate risk. The Company currently does not hedge its foreign exchange exposure.
To date, the Company has not experienced any material loss as a result of
currency fluctuations. However, there can be no assurance that the Company will
not experience material losses in the future as a result of currency
fluctuations.
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon consummation of the Offering, 4,792,974 shares of Common Stock will be
outstanding (4,980,474 shares, assuming exercise of the Underwriters'
over-allotment option). Up to 468,750 additional shares of Common Stock (515,625
shares, assuming exercise of the Underwriters' overallotment option) will be
issuable upon the exercise of the Warrants offered hereby and the Underwriter's
Warrants. 623,164 of the shares that will be outstanding upon consummation of
the Offering are held by officers, directors and other affiliates of the
Company, all of which are freely tradeable, subject to the lock-up described
below. An additional 1,025,292 shares of Common Stock are issuable to such
officers, directors and other affiliates upon the conversion or exercise of
outstanding securities, including stock options. The Company recently registered
for resale 967,042 shares of Common Stock held by or issuable to officers,
directors and other affiliates of the Company upon the exercise or conversion of
outstanding securities which had previously been restricted. The Company also
intends, in the near future, to register for resale an additional 414,500
restricted shares of Common Stock issuable upon exercise of options previously
granted to officers and directors. Thereafter, all 1,381,542 of such shares will
be generally available for sale in the open market by the holders thereof.
    
 
   
     The Company can not predict the effect, if any, that sales of additional
shares of Common Stock or the availability of shares for future sale will have
on the market price of the Common Stock or the Warrants. Sale in the public
market of substantial amounts of Common Stock (including shares issued upon the
exercise or conversion of outstanding securities), or the perception that such
sales could occur, could adversely affect prevailing market prices for the
Common Stock or the Warrants. Such sales also may make it more difficult for the
Company to sell equity securities or equity-related securities in the future at
a time and price that the Company deems appropriate. The officers and directors
of the Company, who hold an aggregate of 681,934 shares of Common Stock
(including shares issuable upon the exercise or conversion of outstanding
securities), have agreed with the Underwriters not to offer or sell, directly or
indirectly, any securities of the Company in the public market for a period of
180 days after the date of this Prospectus, subject to certain exceptions,
without the prior written consent of Janney Montgomery Scott Inc. (the
"Representative"). See "Description of Capital Stock -- Shares Eligible For
Future Sale" and "Underwriting."
    
 
VOLATILITY OF COMMON STOCK PRICE
 
     Prior to the Offering, there have been significant fluctuations in the
trading price of the Common Stock. No assurance can be given that such
volatility will not continue following the completion of the Offering. See
"Price Range of Common Stock."
 
DETERMINATION OF WARRANT EXERCISE PRICE
 
     The exercise price of the Warrants has been set at a premium to the
existing market price of the Common Stock and bears no relationship to any
objective criteria of future value and, accordingly, should in no event be
regarded as an indication of any future market price of the Securities offered
hereby.
 
ABSENCE OF TRADING MARKET FOR THE WARRANTS
 
   
     There currently is no trading market for the Warrants. Although the
Warrants have been approved for inclusion in the NASDAQ NMS, there can be no
assurance that an active market will develop for the Warrants or, if developed,
that it will be maintained. The trading price for the Warrants is expected to be
directly related to the market price for the Common Stock. The market price of
the Common Stock and thus the price for the Warrants are likely to be subject to
significant fluctuation in response to variations in
    
 
                                       10
<PAGE>   12
 
quarterly results of operations, general trends in the market place and other
factors, many of which are not within the Company's control.
 
UNDERWRITER'S WARRANTS
 
   
     In connection with the Offering, the Company has agreed to sell to the
Representative the Underwriter's Warrants pursuant to which the Representative
will have the right to purchase from the Company 125,000 shares of Common Stock
at an exercise price of $10.276 per share and 125,000 Warrants at an exercise
price of $.06 per Warrant. The Underwriter's Warrants are exercisable with
respect to the Common Stock for a period of four years commencing one year after
the date of this Prospectus and with respect to the Warrants underlying the
Underwriter's Warrants for a period of two years following such one-year period.
See "Underwriting." The Underwriter's Warrants, and the Warrants issuable upon
exercise thereof, afford the holders thereof the opportunity, at nominal cost,
to profit from a rise in the market price of the Common Stock, which may
adversely affect the terms upon which the Company could issue additional shares
of Common Stock during the exercise period of the Underwriter's Warrants.
Additionally, the holders of the Underwriter's Warrants, and the Warrants
issuable upon exercise thereof, will most likely exercise the Underwriter's
Warrants and the Warrants issuable upon exercise thereof at a time when the
Company could obtain capital from other sources on terms more favorable than
those contained in the Underwriter's Warrants.
    
 
CERTAIN CHARTER PROVISIONS
 
   
     The Company currently has 7,000,000 shares of Common Stock authorized for
issuance. Upon completion of the Offering, the Company will have 4,792,974
shares of Common Stock outstanding (4,980,474 shares, assuming full exercise of
the Underwriters' over-allotment option). An additional 1,841,490 shares of
Common Stock (1,888,365 shares, assuming full exercise of the Underwriters'
over-allotment option) will be reserved for issuance upon the conversion or
exercise of outstanding securities of the Company. The Company intends to seek
stockholder approval at its next annual meeting of stockholders to increase the
number of shares of Common Stock the Company is authorized to issue. In the
event that the authorized number of shares of Common Stock is not increased, the
Company's ability to issue additional shares of capital stock, including in
connection with acquisitions and subsequent financings, would be significantly
restricted.
    
 
     The Company's Certificate of Incorporation, as amended (the "Certificate of
Incorporation"), contains provisions which require the favorable vote of the
holders of not less than 80% of the outstanding shares of Common Stock for the
approval of any merger, consolidation or other combination with, or sale, lease
or exchange of all or substantially all of the assets of the Company to, another
entity holding more than 10% of the Company's outstanding voting equity
securities or any affiliate of such entity. These provisions could discourage
potential acquisition proposals, delay or prevent a change in control of the
Company and limit the price that certain investors might be willing to pay in
the future for shares of the Common Stock.
 
     The Board of Directors of the Company is empowered to issue shares of
preferred stock without stockholder action. The existence of this "blank check"
preferred stock could render more difficult or discourage an attempt to obtain
control of the Company by means of a tender offer, merger, proxy contest or
otherwise and may adversely affect the prevailing market price of the Common
Stock. The Company currently has no plans to issue additional shares of
preferred stock. In addition, Section 203 of the Delaware General Corporation
Law prohibits certain persons from engaging in business combinations with the
Company. See "Description of Capital Stock."

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from the sale of the Securities offered
hereby are estimated to be approximately $9,215,000 ($10,668,000 if the
Underwriters' over-allotment option is exercised in full), after deducting
underwriting discounts and commissions and estimated offering expenses payable
by the Company. Such proceeds are intended to be applied approximately as
follows:
    
 
        -  $4,000,000 for product development, including research and
           development, tooling and drawing expenses and product testing (see
           "Business -- Strategy");
 
        -  up to $1,000,000 for repayment of the Company's 6% Subordinated
           Convertible Debentures due 1997 (the "Debentures"), to the extent not
           converted as described below;
 
        -  up to $700,000 for repayment of the outstanding indebtedness under
           the Facility (see "Management's Discussion and Analysis of Financial
           Condition and Results of Operations -- Liquidity and Capital
           Resources");
 
        -  up to $700,000 for repayment of BRL's loan (the "ODC Loan") from the
           Ontario Development Corporation ("ODC") (see "Management's Discussion
           and Analysis of Financial Condition and Results of
           Operations -- Liquidity and Capital Resources");
 
        -  $300,000 for expansion of the Company's manufacturing and assembling
           capabilities (see "Business -- Manufacturing and Assembly"); and
 
        -  the balance for general corporate purposes, including additions to
           working capital and inventory.
 
     The Company issued $1,000,000 of the Debentures in July 1996. The
Debentures bear interest at the rate of 6% per annum, are presently convertible
into shares of Common Stock at a conversion rate of $2.75, and mature 30 days
after the consummation of the Offering unless converted prior thereto. Because
the conversion rate of the Debentures is substantially lower than the current
per share price of the Common Stock, the Company anticipates that substantially
all of the Debentures will be converted into shares of Common Stock. Any
Debentures not so converted will be repaid with a portion of the net proceeds of
the Offering. $300,000 of the net proceeds of the Debentures were utilized to
repay the Company's 12 1/2% convertible subordinated debentures due 1996 (the
"Old Debentures"), and the remaining proceeds were added to working capital. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
 
   
     The Facility bears interest at a variable rate (7.25% at September 30,
1996) equal to 1 1/2% above the Bank's prime lending rate, although from time to
time certain amounts thereunder have borne interest at a default rate of 21%.
See Note 5 to Consolidated Financial Statements. Borrowings under the Facility
are payable upon demand and have been used for working capital, including
manufacturing and inventory requirements.
    
 
   
     The ODC Loan bears interest at a variable rate set quarterly by ODC, which
was 10% at September 30, 1996, and matures on April 30, 1997, subject to
renewal. Borrowings under the ODC Loan have been used to support Canadian
export, sales and related production and receivables financing.
    
 
     A portion of the net proceeds of the Offering may be used to make future
strategic acquisitions or to invest in joint ventures, although currently the
Company has no agreement, understanding or commitment with respect to any
acquisition, investment or joint venture.
 
     Pending the applications described above, the Company will invest the
proceeds principally in short-term bank certificates of deposit, highly rated
short-term debt securities, United States governmental obligations, money market
instruments or other highly rated interest-bearing investments with maturities
of less than one year.

     On November 11, 1996, the last reported sale price of the Common Stock was

stockholders of record.
    
 
                                DIVIDEND POLICY
 
     Since inception, the Company has not paid cash dividends on its Common
Stock. The Company currently intends to retain future earnings to support its
growth strategy and does not anticipate paying dividends in the foreseeable
future. Payment of future dividends, if any, will be at the discretion of the
Company's Board of Directors after taking into account various factors,
including the Company's financial condition, results of operations, current and
anticipated cash needs and plans for expansion. The Company is prohibited from
paying cash dividends on the Common Stock unless full cumulative dividends have
been paid or set aside for payment on the Company's Class A Convertible
Preferred Stock and Class B Convertible Preferred Stock at an annual rate of
$.16 per share, which dividends, at the option of the Company, are payable in
cash or shares of Common Stock. See "Description of Capital Stock." In addition,
the ability of the Company to pay dividends has been limited because BRL is
restricted from providing cash to the Company by the terms of the Facility. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources." The Company's ability to pay
dividends on its Common Stock may be further limited in the future by other
legal or contractual restrictions placed on the Company and on the ability of
its subsidiaries to provide cash to the Company.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion and analysis should be read in conjunction with,
and is qualified in its entirety by, the Company's Consolidated Financial
Statements, including the Notes thereto, appearing elsewhere in this Prospectus.
Historical results are not necessarily indicative of trends in operating results
for any future period.
 
OVERVIEW
 
   
     Since 1990, the Company has principally engaged in the design, development,
manufacture and sale of the IONSCAN(R). To a lesser extent, the Company also
manufactures specialty instruments and engages in contract research and
development activities for industrial companies and various governmental
agencies. Prior to 1990, the Company engaged primarily in airborne mineral
exploration utilizing trace particle collection techniques and analysis, and
funded research and development activities, consisting of contracts and grants
received by the Company for research and development on behalf of third parties.
In 1990, the Company decided to use the trace particle expertise gained in its
airborne exploration business and research and development activities to pursue
the more attractive detection instrument market. Accordingly, the Company ceased
its airborne exploration business and began the development of the IONSCAN(R).
For the year ended December 31, 1995 and the nine months ended September 30,
1996, approximately 82% and 91%, respectively, of the Company's consolidated
revenues were derived from the sale and servicing of IONSCAN(R)s and other
speciality instruments.
    
 
   
     The Company sells IONSCAN(R)s in two primary markets, explosives detection
and drug interdiction. The Company sold its first IONSCAN(R) in 1990 and had
sold over 325 units as of September 30, 1996. Historically, the Company sold a
majority of its units for drug interdiction applications. However, during 1996
the Company's sales have been divided almost evenly between the explosives
detection market and the drug interdiction market. Management expects that the
explosives detection market will account for an increasingly significant portion
of the Company's future growth.
    
 
     The Company sells IONSCAN(R)s for between $50,000 and $95,000 per unit,
depending principally on the configuration of the unit and the purchaser's
location. While substantially all of the Company's revenues are denominated in
U.S. dollars, the Company operates in several foreign countries, including
Canada, the United Kingdom and France, and in certain instances, the Company
sells the IONSCAN(R) in other denominations, particularly British pounds and
French francs. In addition, the Company conducts operations in Canada and, as a
result, certain of the Company's costs are incurred in Canadian dollars. To
date, the Company has not experienced significant losses as a result of foreign
currency fluctuations. The Company currently does not hedge its foreign currency
exposure.
 
     The Company manufactures to a sales forecast in order to have inventory
available to meet anticipated demand promptly and, accordingly, does not have a
significant backlog. Management's sales forecast is determined by an analysis of
a number of factors, including, among other things, the customer's need, the
availability of budgeted funds, the status of equipment demonstrations, the
status of any required approvals and the complexity of the customer's
procurement process. The Company also considers the effect of competition in
obtaining an order. The Company has publicly announced its intention to double
its production in the second half of 1996 in order to accommodate anticipated
demand. There can be no assurance that the Company will receive orders for all
of the units to be produced and, if such orders are not received, the Company's
liquidity and results of operations could be materially and adversely affected.
The Company believes that its existing manufacturing facilities, which the
Company intends to supplement through the use of a portion of the proceeds from
the Offering, will be sufficient for the anticipated growth in orders for the
IONSCAN(R) in the foreseeable future.
 
     Through the period ended June 30, 1996, the Company reported two segments
for financial statement purposes: (i) specialty instruments and (ii) funded
research and development. Because of the rapid growth in sales of IONSCAN(R)s
through June 1996, the funded research and development segment is no longer
 
                                       16
<PAGE>   18
 
significant to the Company's consolidated revenues. Accordingly, effective June
30, 1996, the Company ceased reporting segment information.
 
   
     Approximately 72% and 77% of the Company's revenues for the year ended
December 31, 1995 and for the nine months ended September 30, 1996,
respectively, were derived from non-United States sources. Approximately 30% of
revenues in 1995 were derived from customers in Canada.
    
 
     The Company recognizes revenues from the sale of IONSCAN(R)s upon shipment.
Accordingly, changes in delivery dates for relatively few IONSCAN(R)s from one
quarter to another may have a significant impact on the Company's quarterly
results.
 
     Prior to December 1995, the Company controlled Barringer Laboratories, Inc.
("Labco"), a publicly traded company that provides comprehensive
laboratory-based analytical and consulting services in the United States and
Mexico, including environmental monitoring and geochemical analysis for the
hydrocarbon and mineral exploration industries. In order to focus its resources
on its core business and to increase working capital, in December 1995 the
Company entered into a Stock Purchase Agreement with Labco (the "Stock Purchase
Agreement") pursuant to which the Company sold back to Labco 647,238 shares of
Labco's common stock for an aggregate purchase price of $809,000. The purchase
price consisted of the cancellation of all inter-company obligations and
$300,000 in cash. A portion of the net cash proceeds from such sale were
contributed to BRL pursuant to an agreement with the Bank. After giving effect
to the sale, the Company continued to own 437,475 shares of Labco's common
stock. However, under the terms of the Stock Purchase Agreement, Labco retained
an additional 88,260 shares of Labco common stock owned by the Company (the
"Retained Shares"). The Company is only entitled to the return of the Retained
Shares if Labco meets certain pre-tax earnings goals for 1996. The Company also
agreed to terminate all voting arrangements allowing it to vote shares of Labco
common stock not owned by it and agreed for a period of 24 months not to enter
into any such voting arrangements. Labco had the right until January 2, 1997 to
purchase the Company's remaining ownership interest in Labco under certain
circumstances. In addition, the Company agreed to certain restrictions on the
transferability of its remaining Labco stock until January 2, 1997. As a result
of the transactions contemplated by the Stock Purchase Agreement, the Company
reclassified its financial statements, where appropriate, to reflect its prior
interest in Labco as a discontinued operation and commenced using the equity
method of accounting for its remaining interest. See Note 2 of the Notes to
Consolidated Financial Statements.
 
     In October 1996, the Company and Labco entered into a Termination Agreement
(the "Termination Agreement") pursuant to which Labco agreed to waive its right
of first refusal and to terminate the restrictions on the transfer of the
Company's remaining Labco shares. The Company agreed that, for a period of three
months from the date of the Termination Agreement, it would sell such shares at
a price of at least $1.6875 per share (the "Target Price") in a distribution in
which it would not knowingly sell more than 75,000 shares to any one purchaser
or group of related purchasers. Under the Termination Agreement, for such three-
month period, the Company must sell its Labco shares as provided above if it
receives an offer to acquire such shares at a price per share at least equal to
the Target Price. The restrictions described above also apply to any shares of
Labco common stock issuable to the Company upon the exercise of certain warrants
held by the Company. Labco has registered the Company's Labco shares for resale
pursuant to the Securities Act to facilitate such sales.
 
   
     In the Termination Agreement, the Company agreed to surrender to Labco the
Retained Shares and to terminate all remaining inter-company arrangements. In
addition, upon the disposition by the Company of at least 250,000 of its shares
of Labco common stock, Stanley S. Binder and John J. Harte agreed to resign
their positions with Labco.
    
 
   
     As of November 11, 1996, the Company had sold an aggregate of 280,000
shares of Labco common stock and, pursuant to the terms of the Termination
Agreement, Messrs. Binder and Harte have resigned their respective positions
with Labco.

  Nine Months Ended September 30, 1996 Compared to Nine Months Ended September
30, 1995
    
 
   
     Revenues from operations of the Company consist of (a) net sales of its
IONSCAN(R) drug and explosives detection equipment, related accessories and
consumable supplies, maintenance, training and billable repairs; (b) net sales
of other instruments; and (c) revenues derived from funded research and
development grants and contracts. Revenues from operations increased by
$2,808,000, or 61.8%, in the nine months ended September 30, 1996 compared to
the same period in 1995. Net sales of the IONSCAN(R) and related products
increased by approximately $2,592,000, or 75.4%, in the nine months ended
September 30, 1996 compared to the same period in 1995, due to an increase of
108% in the number of units sold. The increase in IONSCAN(R) sales was due to
increased sales of the Model 400 which was introduced in the first quarter of
1995. Net sales of other instruments increased by approximately $336,000, or
113%, in the nine months ended September 30, 1996 compared to the same period in
1995, principally due to work performed on a heavy water analyzer contract,
which was awarded to the Company in mid-1995 and completed in the first half of
1996. In addition, net sales benefited from the sale of several other
instruments. The markets for heavy water analyzers and other instruments are
limited, and therefore management cannot predict whether the Company will
receive any future orders. Revenues derived from funded research and development
decreased by approximately $125,000, or 16.5%, in the nine months ended
September 30, 1996 compared to the same period in 1995. The reduced revenues
were attributable to the Company's contract with the Emergencies Science
Division, Environment Canada to design and build an airborne laser-fluorosensor
system, a substantial portion of which was completed in 1995.
    
 
   
     Gross profit as a percentage of sales for the nine months ended September
30, 1996 increased to 50.4% from 37.4% in the same period last year. The
improvement was primarily attributable to higher margins on international sales,
coupled with larger, more efficient production runs of the IONSCAN(R) and
related products and, to a lesser extent, to slightly improved gross profit from
funded research and development
    
 
                                       18

activities. The sale at higher than expected prices of several Model 350 units
during the first six months of 1996, the carrying value of which had been
reduced in 1995, also attributed to the improvement.
    
 
   
     Selling, general and administrative expenses, consisting primarily of
salaries and related fringe benefits, occupancy costs, professional fees and
travel expenses, increased by approximately $604,000, or 30.9%, for the nine
months ended September 30, 1996 as compared to the same period in 1995. In the
1995 period the Company recognized an expense decrease of $226,000 attributable
to a negotiated reduction in professional fees and $120,000 of additional
expense reduction recognized on the termination of the Company's Canadian
Pension Plan as of December 31, 1993. Excluding these items, selling, general
and administrative expenses in the 1996 period increased by $258,000. As a
percentage of revenues, selling, general and administrative expenses decreased
to 34.8% for the first nine months of 1996 from 43.0% for the same period in
1995. The decrease as a percentage of revenues was primarily attributable to
spreading costs over increased revenues. Selling expenses increased by $350,000,
or 28.0%, for the nine-month period ended September 30, 1996 compared to the
same period in 1995 primarily as a result of increased selling activities,
particularly in Europe.
    
 
   
     For the nine months ended September 30, 1996, unfunded research and
development expenses, consisting primarily of salaries and related benefits and
occupancy costs for product and application development applied to IONSCAN(R)
technology, decreased by approximately $42,000, or 31.6%, compared to the same
period in 1995. The level of unfunded research and development engaged in by the
Company at any time is primarily a function of the resources, both financial and
personnel, that are available at the time.
    
 
   
     Equity in earnings of Labco represents the Company's share of the earnings
and losses of Labco, in which the Company had a 26% ownership interest as of
September 30, 1996. Prior to December 31, 1995, the Company had a controlling
interest in Labco, but since the first quarter of 1995, the Company has
presented Labco as an operation held for sale. Fluctuations in earnings and
losses are dependent upon the performance of Labco. The Company's share of
Labco's net income for the nine-month period ended September 30, 1996 was
$117,000, as compared to $194,000 for the same period in 1995 (where it is shown
under the caption "Income from operation held for sale").
    
 
   
     Other expense, net of income was $1,000 for the nine-month period ended
September 30, 1996 as compared to $83,000 in the same period last year. The
decrease was due to a smaller foreign exchange loss and gains recognized during
the period on trading securities held for pension funding purposes.
    
 
   
     In the nine-month period ended September 30, 1996, the Company had a net
tax benefit of $125,000, composed of current Canadian provincial taxes of
$35,000, offset by a $160,000 reduction in the deferred tax valuation allowance
as a result of changes in management's estimates of the utilization of the
Canadian tax loss carryforwards caused primarily by improved operating results
of BRL. Management anticipates that further deferred tax benefits will be
recognized in the fourth quarter.
    
 
  1995 Compared to 1994
 
   
     Sales of all instruments increased by $34,000, or 0.1%, in 1995 as compared
to 1994. Sales of IONSCAN(R) instruments and related products decreased by
approximately $80,000, or 1.6%. The decrease was due, in part, to the lower
selling price of the new Model 400 IONSCAN(R), which was introduced in the first
quarter of 1995. This reduction in selling price, coupled with other
improvements of the new model, resulted in approximately 36.6% more unit sales.
Sales of instruments other than IONSCAN(R) products increased in 1995 by
approximately $114,000, or 33%, principally due to the award in 1995 of the
contract to build four heavy water analyzers for use at a nuclear facility in
Asia, which was completed in mid-1996. The introduction of the Model 400
resulted in reduced sales of the Model 350. As a result, the Company reduced the
carrying value of the Model 350s remaining in inventory.
    
 
     Revenues of the research and development business increased by
approximately $754,000, or 253.0%, in 1995 as compared to 1994. The improved
sales are attributable to work performed in 1995 under the Company's contract
with the Emergencies Science Division, Environment Canada to design and build an
airborne laser-fluorosensor system.
 
     The Company introduced and made a limited distribution of DrugAlert(TM) in
1995. Sales of such product were not significant.
 
                                       19
<PAGE>   21
 
   
     Gross profit as a percentage of sales for the year ended December 31, 1995
increased to 40.3% from 22.6% in 1994. The gross profit as a percentage of sales
for the research and development business improved to a negative 14.2% in 1995
from a negative 44.6% in 1994. The improvement was due to higher volume which
absorbed a greater portion of the fixed overhead. The gross profit as a
percentage of sales for the instruments business increased to 53.1% in 1995 from
26.4% in 1994. The 1995 gross profit was impacted by the write down of the
carrying value of the Model 350 inventory which aggregated approximately
$442,000, approximately $155,000 of which related to excess spare parts
inventory and the balance to finished goods. In 1994, the Company took a
$792,000 charge against its Model 350 inventory. The consumer products business
had negative gross profit in 1995 due primarily to the expensing of tooling,
software and other development costs.
    
 
     Selling, general and administrative expenses in 1995 decreased by
approximately $47,000, or 1.4%, over 1994. As a percentage of revenues, selling,
general and administrative expenses decreased to 51.9% for 1995 from 60.8% in
1994. The decrease as a percentage of revenues was primarily attributable to
such costs being spread over a higher revenue base. Selling expenses increased
by $759,000, or 48.3%, in 1995. The increase was primarily attributable to the
expenses associated with the Company's Paris, France and London, England offices
being open for a full year and marketing expenses associated with the
DrugAlert(TM) product. General and administrative expenses decreased by
approximately $806,000 in 1995, or 45.3%, over 1994. This reduction was
attributable primarily to the recovery of $147,000 relating to the 1993
conversion of the Canadian pension plan from a defined benefit plan to a money
purchase plan, a reduction in accounts payable of $226,000 relating to a
settlement of professional fees and the effect of staff and expense reductions
implemented in late 1994.
 
     Unfunded research and development in 1995 decreased by approximately
$211,000, or 58.3%, over 1994. The 1994 level was attributable to the completion
of the development of the Company's new Model 400.
 
     Interest expense increased by approximately $38,000 in 1995, or 18.8%, over
1994 levels. The increase is the result of higher levels of borrowing, at higher
interest rates.
 
     Other expense, net of income, in 1995, was approximately $52,000 as
compared to other income, net of expense, in 1994 of approximately $113,000. The
difference of $165,000 was attributable primarily to the changes in exchange
rates which generated a gain of $135,000 in 1994 compared to a loss of $79,000
in 1995.
 
  1994 Compared to 1993
 
     Sales of all instruments for 1994 decreased by $1,545,000, or 22.8%, over
1993. The decrease was attributable to several factors. Management believes that
the pending introduction of the Company's new Model 400 IONSCAN(R) caused a
deferral of purchases until the Model 400 was available. Because of the
announcement of the Model 400, the Company anticipated that its remaining Model
350s would be sold at lower prices over a longer period of time than previously
expected. Accordingly, it offered reduced prices to certain customers as
inducements to secure more timely purchase commitments and reduced prices on
outstanding quotations in order to expedite buying decisions.
 
     Revenues of the research and development business decreased by $711,000, or
70.5%, in 1994 compared to 1993, partially as a result of a decrease in
government sponsored research due to budgetary constraints. In addition, the
Company had several proposals outstanding involving potential new applications
of its IONSCAN technology with U.S., Canadian and European governmental
agencies, which resulted in 1995 revenues for the research and development
business being significantly improved from 1994. See "1995 Compared to 1994."
 
   
     Gross profit for the instrument and research and development businesses as
a percentage of sales for the year ended December 31, 1994 decreased from 49.4%
in 1993 to 22.6% in 1994. The gross profit as a percentage of sales on the
research and development business decreased from 6.5% in 1993 to a negative
44.6% in 1994 and the gross profit as a percentage of sales on the instruments
business decreased from 55.8% in 1993 to 26.4% in 1994. As a result of the
decline in the value of its inventory of Model 350s in 1994, which resulted from
the introduction of the Model 400, the Company provided for approximately
$792,000 in inventory and other charges against the remaining inventory of Model
350s. This charge reduced 1994 gross profit percentage of the instruments
business by approximately 14.3% from 1993. The remaining decrease in
    
 
                                       20
<PAGE>   22
 
gross profit percentage was due primarily to volume variances as a result of
cutbacks in planned Model 350 production to meet the anticipated reduction in
sales levels.
 
   
     Selling, general and administrative expenses in 1994 increased by $235,000,
or 7.5%, over 1993. As a percentage of revenues, selling, general and
administrative expenses increased to 60.8% in 1994 from 40.1% in 1993. The
increase was primarily attributable to such costs being spread over a lower
revenue base. Selling expenses decreased by $274,000 in 1994, or 14.9%, over
1993, as a result of reduced commissions resulting from reduced unit sales
during 1994, offset in part by the expenses incurred in connection with the
opening of the Company's Paris office. General and administrative expenses
increased by $509,000, or 40%, primarily as a result of the impact of the
Canadian pension expense of approximately $75,000 in 1994 against a pension
credit of $206,000 in 1993, which was the result of converting from a defined
benefit plan to a money purchase plan similar to the 401(k) savings plans
available to the Company's U.S. employees. Also, payroll costs increased during
the first three quarters of 1994 in anticipation of increased volume which did
not materialize. Subsequently, significant staff reductions were implemented. In
addition, a reserve against accounts receivable of approximately $110,000 was
established.
    
 
     Unfunded research and development in 1994, applied to IONSCAN(R)
technology, doubled to $362,000 from 1993 levels. The increase was primarily
attributable to the development of the Company's new Model 400 instrument.
 
     Interest expense increased by $38,000, or 23.2%, in 1994, as a result of
higher average borrowings and rising interest rates.
 
     Other income, net of expense in 1994 was approximately $113,000 as compared
to other income, net of expense, in 1993 of approximately $63,000. The
difference is attributable, in part, to foreign exchange gains realized during
1994. Sales of IONSCAN(R) units are quoted in U.S. dollars, while production
costs are incurred in Canadian dollars.
 
     In 1994, the Company had a net reduction in its Canadian deferred tax
assets of $75,000. In 1993, the Company had a net tax benefit of $153,000,
composed of prior years' assessments by Revenue Canada of $147,000 and a net
recognition of $300,000 in Canadian deferred tax assets.
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     The Company sustained net losses of $2,565,000 and $827,000 for the years
ended December 31, 1994 and 1995, respectively, and had an accumulated deficit
of $15,458,000 at September 30, 1996. Although the Company generated net income
of $1,108,000 for the nine months ended September 30, 1996, the Company did not
generate net cash flow from operations during such period as a result of the
Company's need for working capital to support higher levels of accounts
receivable and inventory. The Company's history of losses and its failure to
generate positive operating cash flow have resulted in significant cash
shortages from time to time. See "Risk Factors -- History of Losses" and
"-- Cash Constraints." The Company's cash constraints were exacerbated during
1995 in connection with the introduction of the Company's Model 400 IONSCAN(R),
as customers chose to wait for Model 400s to become available rather than
purchase existing Model 350s.
    
 
     The Company has used the net proceeds of private sales of securities to
fund a portion of its cash flow needs. During 1995, the Company generated net
proceeds of $888,000 from such sales. In July 1996, the Company issued the
Debentures, resulting in net proceeds to the Company of approximately
$1,000,000. The Company used $300,000 of the net proceeds from the sale of the
Debentures to repay the Old Debentures which matured on July 15, 1996. The
remaining net proceeds were added to working capital. The Company intends to use
a portion of the net proceeds of the Offering to repay the Debentures, if
required, and to support its working capital needs. See "Use of Proceeds." The
Company believes that the net proceeds of the Offering will be sufficient to
fund its working capital requirements for at least the next twelve months.
 
   
     In 1995, the Company also financed its working capital requirements in part
through the sale of a portion of its investment in Labco. In October 1996, the
Company entered into an arrangement whereby it intends to sell its remaining
interest in Labco. See "Overview."
    
 
                                       21
<PAGE>   23
 
   
     The Company funds a portion of BRL's operations through the Facility and
the ODC Loan, which are used to support Canadian export production, sales and
related receivables financing. At September 30, 1996, BRL's outstanding
borrowings under these facilities were $860,000, and $600,000 remained available
for future borrowings thereunder, to the extent qualifying collateral is
available to support such additional borrowings. From time to time BRL's
borrowings under the Facility have exceeded the limits set forth therein. In
addition, from time to time BRL has not been in compliance with one or more of
the financial covenants contained therein. See "Risk Factors -- Noncompliance
Under Credit Facility" and Note 5 to Consolidated Financial Statements. The
Company intends to repay the Facility and the ODC Loan out of the net proceeds
of the Offering. Upon completion of the Offering, the Company intends to seek a
new working capital facility to support its operations, although no assurance
can be given that the Company will obtain a facility or as to the terms thereof.
See "Use of Proceeds."
    
 
   
     The Company's capital expenditures relating to its continuing operations
were $120,000, $491,000 and $359,000 for the years ended December 31, 1993, 1994
and 1995, respectively, and $85,000 for the nine months ended September 30,
1996. Such expenditures related primarily to the support of the production of
the IONSCAN(R). During 1995, a portion of such expenditures related to the
opening of the Company's foreign sales offices. Approximately $75,000 of the
1995 expenditures were for development of the DrugAlert product, further
development of which has been suspended. The Company anticipates that total
capital expenditures will be approximately $100,000 for the year ended December
31, 1996, substantially all of which will be used to support production of the
IONSCAN(R). The Company intends to use approximately $300,000 of the net
proceeds of the Offering for expansion of the Company's manufacturing and
assembling capabilities. See "Use of Proceeds."
    
 
   
     The Company has substantial tax loss and research and development tax
credit carryforwards to offset future tax liabilities both in Canada and the
United States. However, the Company utilized all of its Canadian Provincial tax
loss and research and development tax credit carryforwards during the quarter
ended September 30, 1996.
    
 
INFLATION
 
     Inflation was not a material factor in either the sales or the operating
expenses of the Company during the periods presented herein.

                                    BUSINESS
 
OVERVIEW
 
     The Company is principally engaged in the design, development, manufacture
and sale of analytical instruments used for the high sensitivity detection of
trace amounts of plastic and other explosives and illegal narcotics. The
Company's principal product, the IONSCAN(R), is a portable, desk-top instrument
that utilizes a proprietary implementation of ion mobility spectrometry ("IMS")
technology to determine the presence or absence of targeted compounds in a
sample. The IONSCAN(R) can detect targeted substances in amounts smaller than
one-billionth of a gram in approximately six seconds. See "IONSCAN(R)
Technology."
 
   
     The Company's customers are primarily governmental, security and law
enforcement agencies throughout the world, including the Federal Bureau of
Investigation (the "FBI"), the Drug Enforcement Agency (the "DEA"), the General
Services Administration (the "GSA"), the United States, French, and Canadian
customs services and various airports worldwide. Because of its high
sensitivity, the IONSCAN(R) is used both in lieu of and in conjunction with
other detection technologies, such as X-ray, computer aided tomography
("CATSCAN"), quadropole resonance and nuclear magnetic resonance imaging. As of
September 30, 1996, the Company had sold over 325 IONSCAN(R)s, and the Company
believes that, in terms of units sold, it is the world's leading supplier of
trace particle detection instruments.
    
 
     IONSCAN(R)s have been sold for explosives detection applications primarily
outside the United States and for drug interdiction and detection deployment
both within the United States and elsewhere. For example, the IONSCAN(R) is used
in foreign airports, on trains and at the Eurotunnel to check for explosives and
by the United States Coast Guard to check ships and cargo in U.S. territorial
waters for illegal narcotics.
 
     The Company believes that the security-related market for the IONSCAN(R) is
growing as a result of governmental actions, particularly in the United States,
which reflect heightened public safety concerns in the wake of an increasing
number of terrorist acts. Recently, Congress appropriated $144,000,000 for the
purchase of enhanced explosives detection equipment for use at certain airports
in the United States, and the Company believes that a portion of such
appropriation will be utilized for the acquisition of trace particle detection
equipment. Governmental agencies in the United States, including the GSA and the
FAA, have accelerated their evaluation or use of enhanced methods to increase
security measures currently employed in United States airports, other
transportation centers and in public buildings. However, no assurance can be
given as to the growth of the security-related market for the IONSCAN(R).
 
     The Company also believes that the market for the IONSCAN(R) for use in
drug applications will increase as a result of recently reported increases in
domestic drug usage, particularly among teenagers. Various governmental
agencies, including the DEA, have purchased IONSCAN(R)s for use in their efforts
to diminish drug trafficking. Prisons and private entities, including public
utilities and drug rehabilitation clinics, also have purchased IONSCAN(R)s to
detect the presence of drugs. No assurance can be given as to the growth of the
drug interdiction and detection market for the IONSCAN(R).
 
     The Company believes that new markets for the IONSCAN(R) can be developed
in other areas, such as security screening of individuals and process control
and quality assurance in certain industrial applications. In addition, when
coupled with certain other existing technologies, such as gas chromatography,
the IONSCAN(R) can be adapted to other uses, including environmental, biological
and chemical testing. Further, the Company intends to expand the potential uses
of the IONSCAN(R) technology by developing a hand held detector.
 
   
     In addition to the IONSCAN(R), the Company manufactures specialty
instruments and engages in contract research and development activities for
industrial companies and various governmental agencies. For the year ended
December 31, 1995 and the nine months ended September 30, 1996, approximately
25% and 18%, respectively, of the Company's consolidated revenues were derived
from these other activities.
    
 
     The Company was incorporated under the laws of the State of Delaware on
September 7, 1967. The Company's principal executive offices are located at 219
South Street, New Providence, New Jersey 07974, and its telephone number is
(908) 665-8200.

MARKET OVERVIEW
 
  Explosives Detection
 
     Since the 1970s, metal detection equipment and visual inspection have been
employed throughout the world to detect the presence of weapons. Passengers
boarding airplanes pass through metal detectors while carry-on baggage is
scanned by security personnel utilizing X-ray equipment or is searched by hand.
Similar security measures are used in a variety of public buildings, including
courts, where security concerns are particularly high.
 
     The persistent occurrence of terrorist bombings has demonstrated that
currently deployed security measures are inadequate, particularly for the
detection of explosives. While existing screening installations are effective to
detect metallic weapons and other metal objects, they are not always effective
for detecting explosives. In addition, advanced detection equipment has not been
uniformly deployed because of concerns relating to its efficacy, cost and
reliability.
 
     In the aviation security market the need for deployment of more
sophisticated explosives detection systems has been recognized for some time. In
the aftermath of the bombing of Pan Am flight 103 over Scotland in 1988, the
Aviation Security Improvement Act of 1990 (the "Safety Act") was enacted. The
Safety Act directed the FAA to establish a research and development program
related to the development and implementation of explosives detection technology
and procedures to counteract terrorism against civilian aircraft. The Safety Act
directed the FAA to develop certification protocols for explosives detection
equipment and authorized the FAA Administrator to require the use of certified
equipment commencing thirty-six months after enactment.
 
     In response to the requirements of the Safety Act, the FAA began funding
research and development of enhanced explosives detection technology. During the
past five years, the FAA has spent approximately $150,000,000 on such
activities. In addition, the FAA adopted a certification protocol regarding the
use of imaging detection systems for use on checked baggage. The imaging
protocol focuses on (i) the explosive substances to be detected, (ii) the
probability of detection, by explosive, (iii) the quantity of explosive that
must be detected, and (iv) the number of bags processed per hour. In addition
the protocol specifies a maximum acceptable false alarm rate by explosive. To
date, only one imaging system has met the requirements of the protocol. The FAA
has not mandated the deployment of such certified imaging equipment, in part,
because of its cost (approximately $2 million per screening station). Concern
also has been raised about its selectivity because its false alarm rate in
airport testing has been much higher than the protocol results had indicated.
 
     A number of recent events, including the destruction of TWA flight 800 over
Long Island and the bombing at the 1996 Olympics in Atlanta, have refocused
attention on the need to deploy enhanced explosives detection equipment. In
response to the crash of TWA flight 800, the FAA issued a classified security
directive to all airlines subject to FAA regulation. Although the directive is
not publicly available, the Company believes that the directive mandated
enhanced security checks for all baggage checked-in through certain airports
using one of three techniques: manual searching, deployment of certified imaging
equipment and use of trace particle detection equipment. The Company believes
that airlines are using manual searching techniques to comply with the FAA
directive and have not deployed enhanced explosives detection equipment
primarily because of the cost of such equipment which, under existing FAA
regulations, must be borne by the airlines.
 
     On international flights, the FAA has mandated that airlines subject to FAA
regulation comply with the International Civil Aviation Organization's
International Standards and Recommended Practices Safeguarding International
Civil Aviation Against Acts of Unlawful Interference ("Annex 17"). Annex 17
contains generalized recommendations regarding bag matching, the screening of
checked bags and the taking of "appropriate actions" to determine if carry-on
baggage contains explosives. For all international flights, the FAA requires
airlines to use bag matching, to X-ray all carry-on and checked baggage and to
confirm that electronic devices such as cellular telephones, tape recorders and
laptop computers are operational. For certain international flights, the FAA has
mandated more stringent security measures. The Company believes that the FAA
directive augments these procedures in certain respects.
 
                                       24
<PAGE>   26
 
     Annex 17 is implemented in a variety of ways outside the United States. In
the United Kingdom, for instance, certain airports have implemented a tiered
approach to baggage screening that utilizes trace particle detection equipment
to resolve potential security concerns. See "Explosives Applications." Certain
member countries have adopted different security protocols relying on manual
searching or other techniques and many have taken no actions to implement Annex
17.
 
     As a result of the crash of TWA flight 800, the Gore Commission was formed
to examine the security measures currently in place in United States airports
and to make recommendations to the President with respect thereto. The Gore
Commission's initial report made a number of general recommendations regarding
the enhancement of airport security. These recommendations included, among other
things, that the government bear the initial cost of enhanced security
equipment, through ticket surcharges or other methods, that approximately
$160,000,000 be appropriated initially for the purchase of enhanced explosives
detection equipment at major airports, that approximately $50,000,000 be spent
in fiscal 1997 on research and development activities and that cooperation and
sharing of information among agencies be increased.
 
     Partially in response to the Gore Commission's initial report, the
administration asked Congress to appropriate $1.1 billion to fund anti-terrorism
activities. In October 1996, Congress appropriated all the funds recommended by
the administration for fiscal 1997, including $144,000,000 for the purchase of
enhanced explosives detection equipment. A published report indicates that the
administration plans to use a portion of that appropriation to purchase 489
trace detection instruments in fiscal 1997. The Company believes that these
instruments will be used to augment screening of carry-on baggage and to resolve
false alarms reported by imaging equipment. Published reports estimate the total
cost of implementing enhanced explosives detection equipment at the 75 busiest
domestic airports will be upwards of $6 billion and will take ten years to
complete.
 
     The Company believes that the aviation security market for the IONSCAN(R)
will expand significantly as a result of the actions of Congress and the Gore
Commission. While a substantial amount of the initial $144,000,000 appropriated
for the purchase of enhanced explosives detection equipment in fiscal 1997 will
be used to purchase equipment utilizing other technologies, such as CATSCAN,
enhanced X-ray, quadropole resonance and other imaging techniques, the Company
believes that, as indicated above, a significant number of trace particle
detection instruments, including IONSCAN(R)s, will be purchased. In addition,
the appropriation approved by Congress covers only a limited number of United
States airports. The Company believes that additional appropriations will be
required to deploy enhanced explosives detection equipment at all major airports
in the United States. However, there can be no assurance that funding for the
purchase of such equipment will be continued in subsequent fiscal years or as to
the level thereof. In addition, there can be no assurance as to the amount that
will ultimately be spent on the purchase of trace particle detection equipment
or as to the number of IONSCAN(R)s that will actually be purchased or that the
IONSCAN(R) will meet any certification or other requirements that may be adopted
in connection therewith.
 
     Other explosives detection markets for the IONSCAN(R) have been similarly
affected by increased terrorist activity. For instance, as a result of the World
Trade Center bombing in 1990 and the 1995 bombing in Oklahoma City, the Company
has sold IONSCAN(R)s to customers, including the World Trade Center and the GSA,
for facilities protection applications.
 
  Drug Interdiction
 
     The Company believes that concerns regarding the increasing usage of
narcotics will result in substantial growth in the market for IONSCAN(R)s used
in drug detection and interdiction efforts. According to the Office of National
Drug Control Policy, use of certain illegal narcotics significantly increased
during the past five years. Recent surveys have also indicated that the use of
illegal narcotics by teenagers has reached a record level. X-ray scanning,
random searches and the use of canines have not resulted in sufficient progress
in programs to suppress illegal drug trafficking. Accordingly, customs and law
enforcement agencies, particularly in the United States, have increasingly
turned to more sophisticated detection equipment, including the IONSCAN(R), to
assist in their interdiction and detection efforts. The United States Coast
Guard and customs services throughout the world have purchased IONSCAN(R)s for
use in their drug interdiction efforts.
Prisons throughout the United States and around the world also are increasingly
using sophisticated equipment, such as the IONSCAN(R), to reduce drug use.
Various prisons in the United States, as well as in Canada and
 
                                       25
<PAGE>   27
 
Mexico, have purchased IONSCAN(R)s to test visitors, packages, cell blocks and
vehicles for illegal narcotics. The Company believes that the successful
integration of the IONSCAN(R) in drug interdiction and detection activities by
the United States Coast Guard, as well as by the various customs services and
correctional facilities described above, will result in additional purchases of
the IONSCAN(R) for drug interdiction purposes, although no assurance can be
given in such regard.
 
     As a result of increased drug usage and a heightened public awareness
regarding criminal activity generally, governmental agencies have increased
their spending on drug interdiction efforts. In addition, in connection with the
implementation of United States foreign policy, grants have been provided to
foreign countries, particularly in Latin America, for use in drug interdiction
efforts. The Company believes that as a result of the increased governmental
focus on drug prevention and the increased budgetary allocations for drug
intervention programs, the drug detection market for the IONSCAN(R) will
continue to grow, although no assurance can be given as to the growth of the
drug interdiction and detection market for the IONSCAN(R).
 
STRATEGY
 
     The Company's objective is to strengthen its position as the leading
supplier of trace particle detection equipment by (i) further penetrating
existing markets for the IONSCAN(R) through aggressive pursuit of additional
sales from new and existing customers, (ii) expanding the uses of the
IONSCAN(R), particularly for security screening of individuals and for process
control and quality assurance in certain industrial applications, and (iii)
extending the capabilities and the potential uses of the IONSCAN(R) for
environmental, biological and chemical testing by, among other things, combining
the IMS technology used by the IONSCAN(R) with other existing technologies, such
as gas chromatography, and by developing a hand-held detector utilizing the
IONSCAN(R) technology. The following are the key elements of the Company's
strategy to achieve these objectives:
 
  Increased Penetration of Existing Markets
 
     The Company's primary strategic objective is to enhance its sales and
marketing capabilities to take advantage of existing and emerging selling
opportunities. The Company believes that the acceptance of the IONSCAN(R) by
customers worldwide and its performance in the field both for explosives
detection and drug detection place the Company in a favorable position to take
advantage of the expected growth in its markets.
 
  Development of New Applications
 
     The Company is developing new applications for its IONSCAN(R) technology.
For instance, under research grants from the FAA, the Company has begun
development of an individual passenger screening system for the aviation
security market. The Company believes that the IONSCAN(R) is uniquely suited for
this application due to its quick analysis time and high level of throughput in
terms of items checked per hour.
 
     In addition, in the chemical manufacturing and processing industries,
instrumentation is used to ensure that specified chemicals are present and in
the correct proportions and to ensure the absence of other chemicals at various
stages of the process. The Company believes that the IONSCAN(R) is readily
adaptable for use in these applications.
 
  Product Extension
 
     The Company believes that the IONSCAN(R) can be combined with other readily
available technologies, particularly gas chromatography, to enable the
IONSCAN(R) to detect compounds contained in more difficult sampling media, such
as soil. The Company believes that a modified IONSCAN(R) would be able to break
down a complex matrix of chemicals to separate out the background material and
permit testing for the targeted substance on site, instead of requiring shipment
of a sample to an offsite laboratory for analysis. As a result, the modified
IONSCAN(R) could be utilized to field test for the presence of microscopic
organisms and other environmentally sensitive materials. In addition, the
Company intends to use a portion of the net proceeds of the Offering to fund the
development of a handheld detector utilizing the same technology as the
IONSCAN(R). Such an instrument could be used, for instance, by law enforcement
officers to test for the presence of illegal narcotics during an investigation.
 
                                       26

IONSCAN(R) TECHNOLOGY
 
     The IONSCAN(R) is a portable, desktop instrument that utilizes a
proprietary implementation of ion mobility spectrometry to analyze samples for
the presence of targeted chemical compounds in amounts smaller than
one-billionth of a gram. An operator collects samples, either by utilizing a
hand-held suction device that contains a special filter cartridge which collects
the sampled matter or by swiping a cloth or glove across the surface to be
tested and then transferring the sampled matter to the cartridge. After the
sample has been collected, the filter cartridge is placed onto a slide tray on
the front of the IONSCAN(R) and inserted into a heating chamber. The sample is
then rapidly heated causing the sample to vaporize. The molecules contained in
the vapors from the sample are charged electrically converting them into ions
which are collected and then propelled through a testing chamber containing a
controlled mixture of calibrant gases. The speed at which each ion travels
through the testing chamber will vary depending upon its molecular structure.
The IONSCAN(R) measures the time of flight of the ions through the testing
chamber and, utilizing proprietary software containing Company-developed
detection algorithms, determines whether the targeted chemicals are present and
reports the results to the user. If traces of any of the targeted chemical
compounds are present, the IONSCAN(R)'s alarm will ring, a red light on the
IONSCAN(R) will flash and the screen will display a list of the targeted
substances which were detected. If no traces of the targeted substances are
detected, the IONSCAN(R) will display a green light. The IONSCAN(R) analyzes a
sample in approximately six seconds. Because the IONSCAN(R)'s analysis takes
place under high temperature, there is virtually no residue from the sample and,
under normal operating conditions, additional sampling can take place almost
immediately with no need to clean out the testing chamber. The following diagram
illustrates the operation of the IONSCAN(R).
 
              [Schematic showing the operation of the IONSCAN(R)]
 
                                       27
<PAGE>   29
 
     The Company assembles IONSCAN(R)s from components supplied to it by various
suppliers and parts manufactured internally. Once the IONSCAN(R) is assembled,
the IONSCAN(R) is "burned in" for up to 400 hours using certain chemicals to
calibrate and tune the unit and to assure its proper functioning. After
successful completion of this procedure, the IONSCAN(R) is ready for shipment to
a customer.
 
     The Company also has developed the IONSCAN(R) Manager software for use in
conjunction with the IONSCAN(R). The IONSCAN(R) Manager provides the user with
enhanced graphic read-outs of test results enabling the user to view the data in
more detail. Utilizing this software, a user can view multiple test results at
the same time, switch back and forth between test results and highlight
particular areas of interest to obtain greater detail. This software also can be
used to print out or save data and to transfer test results onto a computer disk
for storage, transportation or other uses, such as manipulation in chemical
studies.
 
     In addition, the Company has developed the Barringer Link software, which
allows a remote user to have access to the IONSCAN(R). Typically, this software
is used by the customer to select different testing algorithms for the
IONSCAN(R) or to trouble shoot problems with the unit. A customer has the
capability to test for a different set of chemical compounds by remotely
downloading the necessary algorithms onto its IONSCAN(R). For instance, if a
United States Coast Guard vessel on patrol needs the capability to test a
suspect vessel for a particular type of illegal narcotics, the Coast Guard can
download the required information to its unit. In addition, the Barringer Link
allows the Company or the customer to run certain diagnostic programs to
determine problems which may have occurred within a particular unit and to
correct certain software problems.
 
EXPLOSIVES APPLICATIONS
 
  Aviation Security
 
     IONSCAN(R)s are currently used in explosives detection applications in the
aviation security market primarily outside the United States. In most cases, the
IONSCAN(R) is used to resolve concerns regarding checked or carry-on baggage
that may contain explosives. For instance, certain foreign airports have
implemented a three-tiered security procedure for checked baggage. All checked
bags are screened by an X-ray machine to identify those bags that may contain
explosive materials. Bags identified through that process are then subjected to
a second level of testing, generally using a more sensitive imaging system, such
as enhanced X-ray or CATSCAN. Bags that are not cleared at this second level are
either manually searched or tested using trace particle detection instruments
such as the IONSCAN(R). A number of IONSCAN(R)s have been purchased for this
purpose.
 
     IONSCAN(R)s also are used to augment screening of carry-on baggage. The
carry-on bags of individuals meeting certain passenger profiles are searched
manually (including using bomb sniffing canines), screened by imaging equipment
or scanned using trace particle detection equipment, such as the IONSCAN(R).
Although the IONSCAN(R) was approved in 1992 by the FAA for screening electronic
items, there has been only limited use of it for such purpose.
 
     Although most airports use manual searching to resolve concerns about
checked baggage and to provide enhanced security of certain carry-on baggage,
the Company believes that as a result of recent governmental initiatives,
governmental regulators will require deployment of more sophisticated equipment,
such as the IONSCAN(R). Currently, IONSCAN(R)s are used in 15 airports
throughout the world in explosives detection applications.
 
  Other Transportation Security
 
     IONSCAN(R)s also are employed in explosives detection applications in other
segments of the transportation industry. In Europe, IONSCAN(R)s are in use at
the Eurotunnel, which connects England and France, to scan vehicles and freight
for explosive materials. In addition, IONSCAN(R)s are used by British Rail and
train systems operating in the Eurotunnel to test for explosive materials. The
Company believes that this market will experience substantial growth as
governmental authorities increasingly recognize that terrorist acts, such as the
poison gas incidents in Tokyo in 1995, may involve other forms of public
transportation, such as
 
                                       28
<PAGE>   30
 
railroads and subways. However, there can be no assurance as to the ultimate
size of this market or as to the technologies that will be used to implement any
increased security measures.
 
  Building Security and Forensics
 
     IONSCAN(R)s are deployed at numerous facilities around the world, such as
large electric utilities and landmark buildings, that are perceived as
potentially likely targets for terrorist attacks. For instance, IONSCAN(R)s
currently are in use at the World Trade Center in New York as a result of the
bombing there in 1993. In addition, the Company recently sold several
IONSCAN(R)s to the GSA, which is responsible for the maintenance and security of
U.S. government buildings. In the wake of incidents such as the 1995 Oklahoma
City bombing and the bombing in Atlanta during the 1996 Summer Olympics, the
Company believes that this market will experience significant growth as the need
for physical security measures at public facilities increases, although there
can be no assurance as to the growth of this market for the IONSCAN(R). The
Company believes that the IONSCAN(R) is particularly well suited for this
application because of its fast scanning time, its high throughput and its low
cost compared to other available detection technologies.
 
     Customers, such as the FBI, the New York City Police Department, and
military forces in Europe and the Middle East use the IONSCAN(R) for forensic
purposes to test debris for traces of explosives and other chemicals following
the occurrence of a bombing or explosion. For example, IONSCAN(R)s were used to
test debris from the crash of TWA flight 800 and at the site of the 1995
Oklahoma City bombing.
 
DRUG APPLICATIONS
 
  Drug Interdiction
 
     As a result of the increased usage of illegal narcotics, governmental
agencies in the United States and around the world are refining their drug
interdiction techniques. Metal detectors, X-ray equipment, random manual
searching and the use of canines have not resulted in sufficient progress in
programs to suppress illegal drug trafficking, and governmental agencies have
been increasingly utilizing more sophisticated detection equipment, including
the IONSCAN(R), to supplement their drug interdiction efforts. Currently, law
enforcement agencies around the world, including the FBI, the DEA, customs
officials in the United States and eight other countries, the U.S. and Japanese
Coast Guards, police departments in 10 states and five foreign countries and a
number of federal and foreign prisons use the IONSCAN(R) for this purpose.
IONSCAN(R)s also are in use in drug interdiction efforts in 16 airports
throughout the world.
 
     The Company expects that this market will continue to grow as a result of
continuing drug trafficking, increased governmental attention in this area and
increased budgets for anti-drug activities. The Company believes that it will be
well-positioned to take advantage of the expected growth in this market because
of its large installed base, the breadth of its customers and the field
performance of the IONSCAN(R) to date, although no assurance can be given as to
the growth of the drug interdiction market for the IONSCAN(R).
 
  Drug Detection
 
     The increased usage of illegal narcotics also is driving sales of
IONSCAN(R)s to other entities for drug detection applications. For instance,
several large public utilities have purchased IONSCAN(R)s to test their
facilities, vehicles and employees for the presence of illegal narcotics. In
addition, various prisons in the United States, as well as in Canada and Mexico,
have purchased IONSCAN(R)s to test visitors and packages entering prisons, cell
blocks and vehicles for illegal narcotics. Drug rehabilitation centers also have
purchased IONSCAN(R)s to supplement their testing procedures for patients. The
Company believes that this market segment will experience additional growth as
other large utilities, prisons and drug rehabilitation centers seek to
supplement their current drug detection efforts, although no assurance can be
given as to the growth of the drug detection market for the IONSCAN(R).
 
                                       29
<PAGE>   31
 
SALES AND MARKETING
 
     The Company sells its products through a direct sales and support force of
18 persons located at its headquarters in New Jersey and at its offices in
Toronto, London and Paris. In addition, the Company has a network of independent
sales representatives located throughout Europe, the Middle East, Africa, Asia,
South America and Australia. See "Facilities." The Company also has entered into
sales representative agreements with Mitsubishi Heavy Industries for
distribution of the IONSCAN(R) in Japan. The Company's sales and marketing
efforts typically involve extensive customer visits, demonstrations and field
testing. Sales prospects generally are targeted by the Company or its
independent sales representatives, although the Company also responds to
requests for proposals.
 
     Typically, the Company sells its IONSCAN(R) instruments for prices between
$50,000 and $95,000 per unit, depending principally on the configuration of the
unit and the purchaser's location. Once a sale is consummated, the Company
provides training at a customer's location to teach operators how to use the
IONSCAN(R), including proper sampling techniques. The Company generally provides
a one-year parts and labor warranty on its IONSCAN(R) instruments, although from
time to time the Company has entered into service contracts which include
extended warranties. To date, the Company's warranty claims experience has not
been significant.
 
     The Company does not actively market its other specialty instruments or its
contract research and development services. However, from time to time the
Company responds to appropriate requests for proposals for non-IONSCAN(R)
instruments and such services. Although sales of such instruments and such
services have been material to the Company's historic results from time to time,
as a result of the expected increase in sales of the IONSCAN(R), the Company
does not expect that such sales will materially affect its results of operations
in future periods.
 
     During 1995, no customer accounted for more than 10% of the consolidated
revenues of the Company. During 1994, one customer accounted for 10.8% of the
consolidated revenues of the Company.
 
BACKLOG
 
   
     Although the Company's sales cycle is relatively long due to governmental
budgetary and procurement policies, once orders are placed customers typically
seek immediate delivery. Accordingly, for competitive purposes, the Company
follows the practice of manufacturing to a sales forecast. As a result, the
Company does not have a material backlog of orders for its instruments. The
Company anticipates that all of its instrument backlog at September 30, 1996
will be shipped prior to December 31, 1996. Because the Company's funded
research and development activities are undertaken pursuant to contracts which
typically run for one or more fiscal periods, from time to time the Company has
a backlog relating to research and development activities to be performed in
future periods. Such backlog was not material at September 30, 1996. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
    
 
MANUFACTURING AND ASSEMBLY
 
     The Company manufactures and assembles IONSCAN(R)s at its facility in
Toronto, Canada, and has recently expanded its capabilities to manufacture and
assemble IONSCAN(R)s at its facility in New Providence, New Jersey. The Company
intends to use a portion of the net proceeds from the Offering to augment its
existing manufacturing and assembling capabilities. See "Use of Proceeds."
 
     Although many of the basic components of the IONSCAN(R), such as
chipboards, resistors, capacitors, liquid crystal displays and other similar
components, are readily available from a number of sources, the Company
typically purchases such components from single suppliers. A limited number of
components and sub-assemblies are manufactured for the Company, pursuant to the
Company's proprietary specifications, but the Company does not believe it is
dependent on any single source for these items. To date, the Company has not
experienced any difficulty in obtaining any components or sub-assemblies.

COMPETITION
 
     The Company competes with other entities, a number of which have
significantly greater financial, marketing and other resources than the Company.
Principal competitive factors include selectivity (the ability of an instrument
to identify the presence of a particular substance), sensitivity (the ability of
an instrument to detect small amounts of a particular substance), false alarm
rate, price, marketing, ease of use and speed of analysis. The Company believes
that it competes effectively with respect to each of these factors.
 
     The Company competes for governmental expenditures with equipment
manufacturers utilizing other types of detection technologies, including
CATSCANs, enhanced X-ray and quadropole resonance, as well as with manufacturers
of other IMS equipment and manufacturers using other trace particle detection
technologies, such as gas chromatography and chemoluminescence. Because trace
particle detection equipment is used in certain instances to verify detection
results obtained by other enhanced detection systems, the IONSCAN(R) and other
trace particle detection equipment are used in conjunction with systems
utilizing imaging technologies. As a result of recent governmental initiatives,
the Company anticipates that additional technologies, including improved IMS
technologies, will be developed and that new competitors will enter the
Company's markets. See "Risk Factors -- Dependence on and Effects of Government
Regulation."
 
     In the trace particle detection market, the Company's main competitor is
Thermedics, Inc. ("Thermedics"), which has greater financial, marketing and
other resources than the Company. However, the Company believes that the
IONSCAN(R) has certain advantages over Thermedics' instrument, including faster
speed of analysis, lower cost, greater portability, lower power consumption and
lower weight. Accordingly, the Company believes that it competes effectively
with Thermedics and will continue to do so, although no assurance can be given.
 
     The Company also competes with the present use by various law enforcement
agencies of canines to locate the presence of explosives or drugs. Although
canines have a highly developed sense of smell and are able to follow a trail,
the Company believes that its IONSCAN(R) instruments are more effective and cost
efficient than canines, because they can operate 24 hours a day, have greater
selectivity than canines and can identify the composition of the substance
detected.
 
GOVERNMENT REGULATION
 
     Although the Company's business is not subject to significant government
regulation, government regulation plays a large role in determining the demand
for the IONSCAN(R). In the United States and most foreign countries, the
aviation industry is highly regulated and authorities, such as the FAA in the
United States, have the ability to recommend or mandate use of enhanced
explosives detection equipment.
 
     The FAA has adopted a certification protocol regarding the use of imaging
detection systems for use on checked baggage. See "Overview." The FAA is
currently developing a certification protocol for trace particle detection
equipment, which the Company believes will be finalized in the second quarter of
1997. Once the protocol is adopted, the Company believes that only instruments
meeting the FAA certification requirements will be approved for use by airlines
subject to FAA regulation. Although the final protocol has yet to be adopted,
based on early versions of the testing criteria, as well as discussions with
representatives of the FAA, the Company believes that the IONSCAN(R) will meet
the FAA's certification requirements, although no assurance can be given. The
FAA has approved the IONSCAN(R) for screening of electronic carry-on items, such
as cellular telephones, tape recorders and laptop computers. In addition, the
FAA recently issued a classified security directive that the Company believes
authorizes the use of certain trace particle detection equipment, including the
IONSCAN(R), on carry-on baggage.
 
UNFUNDED RESEARCH AND DEVELOPMENT
 
   
     The Company's research and development expenses totaled $91,000, $151,000,
$362,000 and $182,000, for the nine months ended September 30, 1996 and the
years ended December 31, 1995, 1994 and 1993, respectively. These amounts
primarily relate to the development and enhancement of the Company's IONSCAN(R)
instruments. All of these amounts were funded by the Company.
    
 
                                       31
<PAGE>   33
 
     The Company intends to use a portion of the net proceeds from this Offering
to fund increased research and development of the IONSCAN(R). In addition to
further performance enhancements, the Company intends to combine the IONSCAN(R)
with other existing technologies, such as gas chromatography, to enable the
IONSCAN(R) to detect compounds contained in more difficult sampling media, such
as soil. The Company believes that the modified IONSCAN(R) would be able to
break down a complex matrix of chemicals to separate out the background material
and permit testing for the targeted substance on site instead of shipment of a
sample to an offsite laboratory for analysis. As a result, the modified
IONSCAN(R) could be utilized to field test for the presence of microscopic
organisms and other environmentally sensitive materials. In addition, the
Company intends to use a portion of the net proceeds of the Offering to fund the
development of a hand-held detector utilizing the same technology as the
IONSCAN(R). Such an instrument could be used, for instance, by law enforcement
officers to test for the presence of illegal narcotics during an investigation.
See "Strategy." In order to gain access to technology and manufacturing
expertise, the Company may also use a portion of the net proceeds of the
Offering to make strategic acquisitions or to enter into development joint
ventures. To date, the Company has not entered into any agreements or
understandings with respect to any such acquisitions or joint ventures. See "Use
of Proceeds."
 
PATENTS, TRADEMARKS AND PROPRIETARY RIGHTS
 
     The Company holds, through BRL, an aggregate of 10 patents throughout the
world related to equipment, systems and techniques. While such patents may be
regarded as having substantial value, the Company's current business is not
deemed to be materially dependent upon either the aggregate of such patents or
any one of them individually. The Company relies primarily on unpatented
proprietary know-how in building the IONSCAN(R) which it protects through the
use of nondisclosure agreements and other methods. However, the basic technology
used in the IONSCAN(R) is not proprietary to the Company and the same
functionality contained in the IONSCAN(R) could be duplicated by the Company's
competitors without violating the Company's patents.
 
     The Company's initial development of the IONSCAN(R) was funded in part by
Transport Canada and Revenue Canada. Pursuant to an agreement with the Canadian
government, the Company has received a worldwide, perpetual license to certain
unpatented technology developed from such work and pays Revenue Canada a royalty
equal to 1% of sales of all IONSCAN(R) units. This licensing arrangement remains
exclusive until March 31, 1999. The Company has entered into an agreement in
principle with Revenue Canada, pursuant to which the Company expects to obtain
the right to renew such exclusive arrangement on a year by year basis for up to
ten additional years at which time Revenue Canada would have the right to
license the technology to third parties. Revenue Canada has retained the right
to use the technology and to produce products incorporating such technology
although, to date, Revenue Canada has not attempted to do so.
 
     The Company believes that the IONSCAN(R) registered trademark has gained
recognition in the markets for the Company's products and is a valuable
trademark.

against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement, actually and reasonably incurred by such person in connection
with any threatened, pending or actual suit, action or proceeding (whether
civil, criminal, administrative or investigative in nature or otherwise) in
which such person may be involved by reason of the fact that he or she is or was
a director or officer of the Company or is serving any other incorporated or
unincorporated enterprise in any of such capacities at the request of the
Company. Such provisions may provide indemnification to the officers and
directors of the Company for liability under the Securities Act.
 
     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 Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable.

(1) The exercise price of such options exceeded the market price of the
    underlying Common Stock on December 31, 1995.
 
     BRL maintained a defined benefit pension plan for its Canadian employees
that was terminated on December 31, 1993. Mr. Davies was a participant in that
plan. His projected annual benefit at age 65 has been set at approximately
$54,000, which amount may be subject to change only in response to changes in
the Canadian pension regulatory scheme.
 
1990 OPTION PLAN
 
   
     The Company maintains an option plan (the "1990 Option Plan") pursuant to
which the Company was authorized to issue options covering a total of 100,000
shares of Common Stock. No shares are available for issuance under the 1990
Option Plan. However, options covering a total of 32,500 shares of Common Stock
remain outstanding thereunder. Options granted pursuant to the 1990 Option Plan
are exercisable after the expiration of two years from the date of grant and
expire five years after the date of grant.
    
 
EXERCISE PROGRAM
 
     In connection with the options granted by the Company to its employees, the
Board of Directors has approved a stock option exercise program (the "Exercise
Program"). The Exercise Program permits all employees of the Company and its
subsidiaries who are granted stock options (pursuant to either qualified or
non-qualified plans) to finance the exercise of such options by causing the
Company to issue the shares underlying such options upon receipt by the Company
from the employee of a full-recourse demand note evidencing indebtedness to the
Company in an amount equal to the exercise price. Such loans, which are secured
by the underlying shares of Common Stock, are interest-free for one year from
the date on which the
 
                                       37
<PAGE>   39
 
employee exercises his or her option, after which interest accrues at the prime
rate, which rate is changed monthly. The loans are repaid with a portion of the
proceeds from the sale of the Common Stock to be received by the employees upon
the exercise of their options.
 
EMPLOYMENT AGREEMENTS AND COMPENSATION ARRANGEMENTS
 
     The Company has entered into an Employment Agreement with Stanley S.
Binder, the President and Chief Executive Officer of the Company, (the
"Employment Agreement"), pursuant to which Mr. Binder receives $171,000 as
compensation, subject to increases equal to percentage increases in the Consumer
Price Index as well as by increases authorized by the Company's Executive
Compensation Committee. The Employment Agreement provides that it will be
automatically renewed each year, unless either party gives the other six months
prior written notice of non-renewal. In addition, under the Employment Agreement
Mr. Binder received an option to purchase 25,000 shares of Common Stock at an
exercise price of $4.00 per share, which approximated market value at the time
that the Employment Agreement was executed. In addition, Mr. Binder received a
non-qualified option to purchase 25,000 shares of Common Stock at an exercise
price of $8.00 per share, subject to anti-dilution provisions, which option
became exercisable immediately as to all shares subject thereto. Such
non-qualified option has been exercised by Mr. Binder, pursuant to the Stock
Option Exercise Program. See "Certain Relationships and Related Transactions."
During 1995, Mr. Binder received a non-qualified option to purchase 45,000
shares of the Company's Common Stock at $2.00 per share.
 
   
     The Company has entered into employment agreements with both Kenneth S.
Wood and Richard S. Rosenfeld which run for a term of one year from November 1,
1996, subject to automatic renewal unless either the employee or the Company
gives the other party to the employment agreement 90 days' prior written notice
of non-renewal. Pursuant to the employment agreements, Messrs. Wood and
Rosenfeld receive annual base salaries of $111,815 and $96,000, respectively,
subject to periodic increases at the discretion of the Board of Directors, and
are entitled to participate in any cash bonus plan maintained by the Company.
Both of the employment agreements provide, among other things, that, in the
event of a termination of employment by the Company without cause, or a
termination by the employee in certain circumstances following a "change in
control" of the Company, the employee will be entitled to receive certain
severance benefits (payable in equal monthly installments) determined on a
formula basis. Both of the employment agreements also contain certain
confidentiality and non-competition provisions which continue in effect
following the termination of the employee's employment by the Company.
    
 
     The Company has entered into a Consulting Agreement with John J. Harte (the
"Consulting Agreement") pursuant to which Mr. Harte receives $2,000 per month as
compensation. The Consulting Agreement provides that it will be automatically
renewed each year, unless either party gives the other six months prior written
notice of non-renewal. In addition, under the Consulting Agreement, Mr. Harte is
entitled to participate in any grant of stock options to outside board members.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     The Company's Compensation Committee is comprised of Messrs. Abernathy,
Harte and McGrath. During the fiscal year ended December 31, 1995, Mr. Harte was
also the Vice President, Special Projects, of the Company. Messrs. Abernathy and
McGrath were not officers or employees of the Company during fiscal 1995.
 
   
     Until November 1996, Mr. Harte was Chairman of the Board of Labco, and Mr.
Binder was a Director of Labco. Mr. Binder also served on the compensation
committee of Labco's Board of Directors. Except as described herein, no
executive officer of the Company and no member of the Compensation Committee is
a member of any other business entity that has an executive officer that sits on
the Company's Board or on the Compensation Committee. In January 1996, Mr.
Binder received an option to purchase 10,000 shares of Labco common stock at an
exercise price equal to the fair market value of the Labco common stock on the
date of grant. For certain other transactions between Labco and the Company, see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Overview."

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
     Pursuant to the Exercise Program, on April 21, 1994, Mr. Binder and Mr.
Wood exercised options to purchase 37,500 shares of Common Stock and 10,000
shares of Common Stock, respectively, in exchange for which Mr. Binder and Mr.
Wood executed notes payable to the Company in the amount of $203,000 and
$71,600, respectively. In 1995, for the period in which no interest accrued to
the Company (from January 1, 1995 through April 21, 1995), Mr. Binder and Mr.
Wood received benefits of $5,469 and $1,929 respectively, under the Stock Option
Exercise Program, representing interest otherwise payable on such notes.
 
     On May 9, 1995 the Company sold to SSF III, of which Mr. Binder is an
independent General Partner with approximately .01% interest in such
partnership, and to the Cayman Fund, an affiliate of SSF III (collectively, with
SSF III, "SSF"), an aggregate of 125 units at a purchase price of $6,000 per
unit for an aggregate purchase price of $750,000. Each unit consisted of 2,500
shares of Common Stock and a five-year warrant to purchase 2,500 shares of
Common Stock at $1.96 per share, subject to certain anti-dilution provisions. As
an inducement to enter into the transaction and in lieu of a transaction fee,
the Company also issued to SSF warrants, exercisable for three years, to
purchase an aggregate of 37,500 shares of Common Stock at $1.96 per share,
subject to certain anti-dilution provisions. In addition, on June 30, 1995, the
Company sold 22 units to certain officers and directors of the Company for an
aggregate purchase price of $132,000. Such units were identical to those sold to
SSF.

     In July 1996, as part of a private placement and on the same terms as all
other investors, the Company issued Debentures in an aggregate amount of $50,000
and $150,000 to Herbert Gardner and William Barrett, respectively. Herbert
Gardner and William Barrett are officers of the Representative of the
Underwriters. Mr. Gardner and Mr. Barrett purchased the Debentures without any
understanding or agreement regarding this Offering. As part of the same private
placement, certain officers and directors of the Company purchased Debentures in
an aggregate principal amount of $100,000, and SSF purchased $450,000 in
principal amount of the Debentures.
    
 
                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
     The following is a brief summary of certain provisions of the capital stock
of the Company. Such summary does not purport to be complete and is qualified in
all respects by reference to the actual text of the Certificate of
Incorporation, a copy of which has been filed as an exhibit to the Registration
Statement of which this Prospectus is a part.
 
   
     The Company's authorized capital stock consists of 7,000,000 shares of
Common Stock, par value $.01 per share, 1,000,000 shares of Convertible
Preferred Stock, par value $1.25 per share, and 4,000,000 shares of Preferred
Stock, par value $2.00 per share, of which 270,000 shares are designated as
Class A Convertible Preferred Stock and 730,000 shares are designated as Class B
Convertible Preferred Stock. As of November 8, 1996, the Company had outstanding
3,542,974 shares of Common Stock, no shares of Convertible Preferred Stock,
60,165 shares of Class A Convertible Preferred Stock and 122,500 shares of Class
B Convertible Preferred Stock. Upon completion of the Offering, the Company will
have outstanding 4,792,974 shares of Common Stock (4,980,474 shares if the
Underwriters' over-allotment option is exercised in full). In addition, the
Company will have 1,841,490 shares of Common Stock (1,888,365 shares if the
Underwriters' overallotment option is exercised in full) reserved for issuance
pursuant to outstanding options and the Warrants, and upon conversion or
exercise of outstanding securities. See "Shares Eligible For Future Sale." As of
November 8, 1996, there were approximately 1,000 record holders of Common Stock.
    
 
COMMON STOCK
 
     The holders of shares of Common Stock are entitled to one vote for each
share on all matters on which the holders of Common Stock are entitled to vote.
Subject to the rights of the outstanding shares of Convertible Preferred Stock
and Preferred Stock, the holders of the Common Stock are entitled to receive
ratably such dividends as may be declared by the Company's Board of Directors
out of funds legally available therefor. Holders of Common Stock are entitled to
share ratably in the net assets of the Company upon liquidation or dissolution
after payment or provision for all liabilities and the preferential liquidation
rights of the Convertible Preferred Stock and Preferred Stock then outstanding.
The holders of Common Stock have no pre-emptive rights to purchase any shares of
any class of stock of the Company. All outstanding shares of Common Stock are,
and the shares of Common Stock to be issued pursuant to the Offering will be,
upon payment therefor, fully paid and nonassessable.
 
PREFERRED STOCK
 
     The Company's Preferred Stock may be issued from time to time in one or
more classes or series, and the Company's Board of Directors is authorized,
subject to any limitations prescribed by Delaware law, to fix the rights,
preferences and privileges of the shares and the qualifications, limitations or
restrictions thereon, the number of shares constituting such class or series and
the designation thereof, without any further vote or action by the stockholders.
Unless the designations establishing a particular series of Preferred Stock
provide that the shares of such series of Preferred Stock rank junior to the
Convertible Preferred Stock, all outstanding shares of Preferred Stock will rank
pari passu with the Convertible Preferred Stock.
 
     One of the effects of undesignated Preferred Stock may be to enable the
Board of Directors to render more difficult or to discourage an attempt to
obtain control of the Company by means of a tender offer, proxy contest, merger
or otherwise, and thereby to protect the continuity of the Company's management.
Depending upon the rights of such Preferred Stock, the issuance of additional
Preferred Stock could adversely affect the
 
                                       41
<PAGE>   43
 
holders of Common Stock. For example, Preferred Stock issued by the Company may
rank senior to the Common Stock as to dividend rights, liquidation preference or
both, may have full or limited voting rights and may be convertible into shares
of Common Stock. Accordingly, the issuance of shares of Preferred Stock may
discourage bids for the Common Stock at a premium or may otherwise adversely
affect the market price of the Common Stock.
 
     The Company's Board of Directors has designated two series of Preferred
Stock, the Class A Convertible Preferred Stock and the Class B Convertible
Preferred Stock.
 
  Class A Convertible Preferred Stock
 
     Holders of Class A Convertible Preferred Stock are entitled to receive or
have set apart for payment, when and as declared by the Company's Board of
Directors, cumulative dividends at an annual rate of $.16 per share, payable
semiannually in cash or shares of Common Stock at the Company's option. Holders
of shares of Class A Convertible Preferred Stock are entitled to convert each
share of Class A Convertible Preferred Stock into .361745 of a share of Common
Stock. The number of shares of Common Stock into which each share of Class A
Convertible Preferred Stock is convertible is subject to adjustment in certain
events. The Class A Convertible Preferred Stock is redeemable any time, at the
Company's option, after the closing price of the Common Stock has been $12.00 or
more for 90 consecutive trading days, in whole or in part, at $2.00 per share,
plus accrued dividends. In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the affairs of the Company, holders of
Class A Convertible Preferred Stock will be entitled to a liquidation preference
of $2.00 per share plus accrued dividends. Holders of Class A Convertible
Preferred Stock are entitled to vote on all matters on which the holders of
shares of Common Stock are entitled to vote, vote together with the holders of
the Common Stock the Convertible Preferred Stock and the Class B Convertible
Preferred Stock as a single class, and in such circumstances will be entitled to
that number of votes which is equal to the number of shares of Common Stock into
which each share of Class A Convertible Preferred Stock held by such holder is
then convertible. Holders of Class A Convertible Preferred Stock also are
entitled to vote as a class in certain limited circumstances.
 
  Class B Convertible Preferred Stock
 
     Holders of Class B Convertible Preferred Stock are entitled to receive or
have set apart for payment, when and as declared by the Company's Board of
Directors, cumulative dividends at an annual rate of $.16 per share, payable
semiannually in cash or shares of Common Stock at the Company's option. Holders
of shares of Class B Convertible Preferred Stock are entitled to convert each
share of Class B Convertible Preferred Stock at any time after the date of
issuance thereof, into .355839 of a share of Common Stock. The number of shares
of Common Stock into which each share of Class B Convertible Preferred Stock is
convertible is subject to adjustment in certain events. The Class B Convertible
Preferred Stock is redeemable any time, at the Company's option, after the
closing price of the Common Stock has been $12.00 or more for 90 consecutive
trading days, in whole or in part, at $2.00 per share, plus accrued dividends.
In the event of any voluntary or involuntary liquidation, dissolution or winding
up of the affairs of the Company, holders of Class B Convertible Preferred Stock
will be entitled to a liquidation preference of $2.00 per share, plus accrued
dividends. Holders of Class B Convertible Preferred Stock are entitled to vote
on all matters on which the holders of Common Stock are entitled to vote,
together with the holders of Common Stock, the Convertible Preferred Stock and
the Class A Convertible Preferred Stock as a single class, and in such
circumstances will be entitled to that number of votes which is equal to the
number of shares of Common Stock into which each share of Class B Convertible
Preferred Stock held by such holder is then convertible. Holders of Class B
Convertible Preferred Stock also are entitled to vote as a class in certain
limited circumstances.
 
CONVERTIBLE PREFERRED STOCK
 
     No Convertible Preferred Stock is currently issued or outstanding, and the
Company has no current plan to issue any shares of Convertible Preferred Stock.
Holders of Convertible Preferred Stock, when and if issued, will be entitled to
receive or have set apart for payment, when and as declared by the Company's
Board of Directors, cumulative dividends at an annual rate of $.10 per share,
payable semi-annually in Common
 
                                       42
<PAGE>   44
 
   
Stock. Holders of shares of Convertible Preferred Stock will be entitled to
convert each share of Convertible Preferred Stock at any time prior to the
fourth anniversary of the date of issuance thereof, into one (1) share of Common
Stock. The Company will be entitled to force a conversion of the Convertible
Preferred Stock, but not with respect to less than all of the outstanding
shares, upon the occurrence of certain events. The number of shares of Common
Stock into which each share of Convertible Preferred Stock is convertible is
subject to adjustment in certain events. In the event of any voluntary or
involuntary liquidation, dissolution or winding up of the affairs of the
Company, holders of Convertible Preferred Stock will be entitled to a
liquidation preference of $1.25 per share. Holders of Convertible Preferred
Stock will be entitled to vote on all matters on which the holders of Common
Stock vote, together with the Common Stock, the Class A Convertible Preferred
Stock and the Class B Convertible Preferred Stock as a single class, and in such
circumstances will be entitled to that number of votes which is equal to the
number of shares of Common Stock into which each share of Convertible Preferred
Stock held by such holder is then convertible. Holders of Convertible Preferred
Stock will also be entitled to vote as a class in certain circumstances
including, a merger, consolidation, a sale of substantially all of the Company's
assets and the adoption of stock option or other incentive plans.
    
 
CERTAIN CHARTER PROVISIONS
 
     The Company's Certificate of Incorporation contains provisions which
require the favorable vote by the holders of not less than 80% of the
outstanding shares of Common Stock for the approval of any merger, consolidation
or other combination with, or sale, lease or exchange of all or substantially
all of the assets of the Company to, another entity holding more than 10% of the
Company's outstanding voting equity securities or any affiliate of such entity.
These provisions could discourage potential acquisition proposals, delay or
prevent a change in control of the Company and limit the price that certain
investors might be willing to pay in the future for shares of the Company's
Common Stock.
 
SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW
 
     Section 203 of the Delaware General Corporation Law generally restricts a
corporation from entering into certain business combinations with an interested
stockholder (defined as any person or entity that is the beneficial owner of at
least 15% of a corporation's voting stock) or its affiliates for a period of
three years after the date of the transaction in which the person became an
interested stockholder unless (i) the transaction is approved by the board of
directors of the corporation prior to such business combination, (ii) the
interested stockholder acquires 85% of the corporation's voting stock in the
same transaction in which it exceeds 15%, or (iii) the business combination is
approved by the board of directors and by a vote of two-thirds of the
outstanding voting stock not owned by the interested stockholder. The Delaware
General Corporation Law provides that a corporation may elect not to be governed
by Section 203. At present, the Company does not intend to make such an
election. Section 203 may render more difficult a change in control of the
Company or the removal of incumbent management.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Common Stock and the Warrants is
American Stock Transfer & Trust Company, New York, New York.
 
SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon consummation of the Offering, 4,792,974 shares of Common Stock will be
outstanding (4,980,474 shares, assuming exercise of the Underwriters'
over-allotment option). Up to 468,750 additional shares of Common Stock (515,625
shares, assuming exercise of the Underwriters' overallotment option) will be
issuable upon the exercise of the Warrants offered hereby and the Underwriter's
Warrants. 623,164 of the shares that will be outstanding upon consummation of
the Offering are held by officers, directors and other affiliates of the
Company, all of which are freely tradeable, subject to the lock-up described
below. An additional 1,025,292 shares of Common Stock are issuable to such
officers, directors and other affiliates upon the conversion or exercise of
outstanding securities, including stock options. The Company recently registered
for resale 967,042 shares of Common Stock held by or issuable to officers,
directors and other affiliates of the Company upon the exercise or conversion of
outstanding securities which had previously been restricted. The
    
 
                                       43
<PAGE>   45
 
Company also intends, in the near future, to register for resale an additional
414,500 restricted shares of Common Stock issuable upon exercise of options
previously granted to officers and directors. Thereafter, all 1,381,542 of such
shares will be generally available for sale in the open market by the holders
thereof.
 
   
     The officers and directors of the Company, who hold an aggregate of 681,934
shares of Common Stock (including shares issuable upon the exercise or
conversion of outstanding securities), have agreed with the Underwriters not to
offer or sell, directly or indirectly, any securities of the Company in the
public market for a period of 180 days after the date of this Prospectus,
subject to certain exceptions, without the prior written consent of the
Representative. See "Underwriting."
    
 
                            DESCRIPTION OF WARRANTS
 
     The following is a brief summary of certain provisions of the Warrants.
Such summary does not purport to be complete and is qualified in all respects by
reference to the actual text of the Warrant Agreement (the "Warrant Agreement")
between the Company, the Representative and American Stock Transfer & Trust
Company (the "Warrant Agent"). A copy of the Warrant Agreement has been filed as
an exhibit to the Registration Statement of which this Prospectus is a part. See
"Additional Information."
 
EXERCISE PRICE AND TERMS
 
   
     Each Warrant entitles the registered holder thereof to purchase one-quarter
of a share of Common Stock at an exercise price of $9.847 per share prior to
November 12, 1999 subject to adjustment in accordance with the anti-dilution and
other provisions referred to below. The holder of any Warrant may exercise such
Warrant by surrendering the certificate representing the Warrant to the Warrant
Agent, with the subscription form thereon properly completed and executed,
together with payment of the exercise price. The Warrants may be exercised at
any time in whole or in part at the exercise price then in effect until
expiration or redemption of the Warrants. No fractional shares will be issued
upon the exercise of the Warrants.
    
 
     The exercise price of the Warrants has been set at a premium to the
existing market price of the Common Stock and bears no relationship to any
objective criteria of future value and, accordingly, should in no event be
regarded as an indication of any future market price of the Securities offered
hereby.
 
ADJUSTMENTS
 
     The exercise price and the number of shares of Common Stock purchasable
upon the exercise of the Warrants are subject to adjustment upon the occurrence
of certain events, including stock dividends, stock splits, combinations or
reclassifications of the Common Stock, or sale by the Company of shares of its
Common Stock or other securities convertible into Common Stock (exclusive of
shares issued upon the exercise or conversion of outstanding options, warrants
and convertible securities) at a price below the market price (as defined) of
the Common Stock. Additionally, an adjustment would be made in the case of a
reclassification or exchange of Common Stock, consolidation or merger of the
Company with or into another corporation (other than a consolidation or merger
in which the Company is the surviving corporation) or sale of all or
substantially all of the assets of the Company in order to enable Warrant
holders to acquire the kind and number of shares of stock or other securities or
property receivable in such event by a holder of the number of shares of Common
Stock that might otherwise have been purchased upon the exercise of the Warrant.
 
REDEMPTION PROVISIONS
 
   
     Commencing six months from the date of this Prospectus, the Warrants are
subject to redemption by the Company, at $.25 per Warrant (subject to adjustment
under certain circumstances), upon not less than 30 days' prior written notice,
if the bid price of the Common Stock as reported by NASDAQ averages in excess of
200% of the exercise price of the Warrants for a period of 30 days ending within
15 days of the redemption notice date. In the event that the Company exercises
the right to redeem the Warrants, such
    
 
                                       44
<PAGE>   46
 
Warrants will be exercisable until the close of business on the date for
redemption fixed in the redemption notice. If any Warrant called for redemption
is not exercised by such time, it will cease to be exercisable and its holder
will be entitled only to the redemption price.
 
TRANSFER, EXCHANGE AND EXERCISE
 
   
     The Warrants are in registered form and may be presented to the Warrant
Agent for transfer, exchange or exercise at any time on or prior to the earlier
of (i) the business day prior to the redemption date, or (ii) their expiration
date three years from the date of this Prospectus, at which time the Warrants
become wholly void and of no value. If a market for the Warrants develops, the
holder may sell the Warrants instead of exercising them. There can be no
assurance, however, that a market for the Warrants will develop or continue.
    
 
WARRANT HOLDER NOT A STOCKHOLDER
 
     The Warrants do not confer upon holders any voting, dividend or other
rights as stockholders of the Company.
 
MODIFICATION OF WARRANTS
 
     The Company and the Warrant Agent may make such modifications to the
Warrants as they deem necessary and desirable that do not adversely affect the
interests of the warrant holders. The Company may, in its sole discretion, lower
the exercise price of the Warrants for a period of not less than thirty days on
not less than thirty days' prior written notice to the warrant holders and the
Representative. Except as described above, modification of the number of
securities purchasable upon the exercise of any Warrant, the exercise price and
the expiration date with respect to any Warrant or any other modification to the
Warrants requires the consent of the holders of two-thirds of the outstanding
Warrants.
 
     The Warrants are not exercisable unless, at the time of the exercise, the
Company has a current prospectus covering the shares of Common Stock issuable
upon exercise of the Warrants, and such shares have been registered, qualified
or are deemed to be exempt under the securities laws of the state of residence
of the exercising holder of the Warrants. Although the Company will use its best
efforts to have all the shares of Common Stock issuable upon exercise of the
Warrants registered or qualified on or before the exercise date and to maintain
a current prospectus relating thereto until the expiration of the Warrants,
there can be no assurance that it will be able to do so.
 
     The Warrants are separately transferable immediately upon issuance.
Although the Securities will not knowingly be sold to purchasers in
jurisdictions in which the Securities are not registered or otherwise qualified
for sale, purchasers may buy Warrants in the aftermarket in, or may move to,
jurisdictions in which the shares underlying the Warrants are not so registered
or qualified during the period that the Warrants are exercisable. In this event,
the Company would be unable to issue shares to those persons desiring to
exercise their Warrants, and holders of Warrants would have no choice but to
attempt to sell the Warrants in a jurisdiction where such sale is permissible or
allow them to expire unexercised.
 
UNDERWRITER'S WARRANTS
 
   
     In connection with this Offering, the Company has authorized the issuance
of the Underwriter's Warrants and has reserved 156,250 shares of Common Stock
for issuance upon exercise of such Underwriter's Warrants (including the
Warrants issuable upon exercise of the Underwriter's Warrants). The
Underwriter's Warrants will entitle the holder to acquire 125,000 shares of
Common Stock at an exercise price of $10.276 per share and 125,000 Warrants at
an exercise price of $.06 per Warrant. See "Underwriting."

     The obligations of the Underwriters are subject to certain conditions
precedent. The Underwriters are obligated to take and pay for all of the
Securities offered hereby (other than those covered by the over-allotment option
described below), if any such Securities are taken.
 
   
     The Underwriters for whom Janney Montgomery Scott Inc. is acting as
representative (the "Representative") propose to initially offer the Securities
directly to the public at the initial offering price set forth on the cover page
hereof and to certain dealers (who may be Underwriters) at a price that
represents a concession not in excess of $.40 per Share and $.002 per Warrant
under the initial offering price. The Underwriters may allow, and such dealers
may reallow, a concession not in excess of $.10 per Share to other Underwriters
or to certain other dealers. After the commencement of the offering, the public
offering prices and such concessions may be changed by the Representative. The
Representative has informed the Company that it does not expect sales to
discretionary accounts by the Underwriters to exceed five percent of the
Securities offered hereby.
    
 
     The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to 187,500 additional
Shares and 187,500 additional Warrants at the offering prices set forth on the
cover page hereof, less Underwriting discounts and commissions. The Underwriters
may exercise such option to purchase additional Shares and Warrants solely for
the purpose of covering over-allotments, if any, incurred in connection with the
sale of the Securities offered hereby.
 
     The Company and the Underwriters have agreed to indemnify each other
against certain liabilities that may be incurred in connection with the
Offering, including liability that may be incurred in connection with the
Offering under the Securities Act. In addition to underwriting discounts and
commissions, the Company has agreed to pay the Representative a non-accountable
expense allowance equal to 2% of the gross proceeds of this Offering.
 
     The Company, and its present executive officers and directors, have agreed
not to offer, pledge, sell, contract to sell, grant any option for the sale of,
or otherwise dispose of, directly or indirectly, any securities of the Company
for a period of 180 days after the date of this Prospectus, subject to certain
exceptions, without the prior written consent of the Representative.
 
                                       46

     Certain Underwriters may engage in passive market making transactions in
the Common Stock on the NASDAQ Stock Market in accordance with Rule 10b-6A under
the Exchange Act prior to the commencement of offers or sales of Common Stock
offered hereby. Passive market making consists of displaying bids and effecting
transactions in the Common Stock at a price that is not in excess of the highest
bid price for the Common Stock that is displayed on NASDAQ by a market maker who
is not an Underwriter or an affiliated purchaser. New purchases on each day by a
passive market maker are limited to 30% of the average daily trading volume in
the Common Stock during the applicable period.
 
     Although it has no obligation to do so, the Representative currently
intends to make a market in the Company's Securities and may otherwise effect
transactions in such Securities. Such market-making activity may be discontinued
at any time.
 
   
     In connection with this offering, the Company has agreed to sell to the
Representative, at a purchase price of $.0012 per Underwriter's Warrant,
Underwriter's Warrants to purchase from the Company 125,000 shares of Common
Stock at an exercise price of $10.276 per share (the "Exercise Price") and
125,000 Warrants (the "Underlying Warrants") at an exercise price of $.06 per
Warrant. Each Underlying Warrant entitles the holder to purchase one-quarter of
a share of Common Stock at an exercise price of $9.847 per share. The
Underwriter's Warrants are exercisable with respect to the Common Stock for a
period of four years commencing one year after the date of this Prospectus and
with respect to the Underlying Warrants for a period of two years following such
one-year period. The Underwriter's Warrants and the Underlying Warrants provide
for adjustment in the number of shares of Common Stock issuable upon the
exercise thereof as a result of certain events, including stock dividends, stock
splits, combinations and issuance of Common Stock for consideration less than
the Exercise Price, subject to certain exceptions. The Underwriter's Warrants
are restricted and may not be sold, transferred, assigned or hypothecated for a
period of one year from the date of this Prospectus, except to officers of the
Representative. The holders of Underwriter's Warrants and Underlying Warrants
have no voting, dividend or other rights as stockholders of the Company with
respect to shares underlying such warrants, or shares purchasable upon exercise
of such warrants until and to the extent shares of Common Stock have been
purchased, upon exercise of such warrants.
    
 
     If the Underwriter's Warrants to purchase Common Stock or the Underlying
Warrants are exercised, the value of the Common Stock held by public investors
will be diluted. The Underwriter's Warrants and the Underlying Warrants afford
the holders thereof the opportunity, at nominal cost, to profit from a rise in
the market price of the Common Stock, which may adversely affect the terms upon
which the Company could issue additional shares of Common Stock during the
four-year exercise period.
 
     A new registration statement or post-effective amendment to the
registration statement of which this Prospectus is a part will be required to be
filed and declared effective before distribution to the public of shares of
Common Stock issuable upon exercise of the Underwriter's Warrants and the
Underlying Warrants (the "Warrant Shares"). The Company has agreed, on one
occasion when requested by the holders of a majority of the Warrant Shares and
the Underlying Warrants, to make necessary filings, at its expense (subject to a
maximum of $25,000), to permit a public offering of the Warrant Shares during
the period beginning one year after the date of this Prospectus and ending four
years thereafter, and to use its best efforts to cause such filing to become
effective and remain effective for a period of at least one year. In addition,
the Company has agreed, during the period commencing at the beginning of the
second year and concluding at the end of the fifth year after the effective date
of the Registration Statement, to give advance notice to holders of
Underwriter's Warrants, Underlying Warrants and Warrant Shares of its intention
to file a registration statement and, in such case, holders of such securities
shall have the right to require the Company to include the Warrant Shares and
the Underlying Warrants in such registration statement at the Company's expense
and to maintain the effectiveness of such registration statement for a period of
at least one year.
 
   
     In July 1996, Messrs. William J. Barrett and Herbert M. Gardner, officers
of the Representative, purchased Debentures from the Company in the principal
amount of $150,000 and $50,000, respectively. See "Use of Proceeds" and "Certain
Relationships and Related Transactions." The Debentures, when converted in
accordance with their terms, will entitle Messrs. Barrett and Gardner to receive
from the Company 54,545 and 18,181 shares of Common Stock, respectively.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
Barringer Technologies Inc.
New Providence, New Jersey
 
     We have audited the accompanying consolidated balance sheets of Barringer
Technologies Inc. as of December 31, 1995 and 1994 and the related consolidated
statements of operations, stockholders' equity, and cash flows for each of the
three years in the period ended December 31, 1995. 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 financial position of Barringer
Technologies Inc. at December 31, 1995 and 1994 and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1995 in conformity with generally accepted accounting principles.

                   SEPTEMBER 30, 1996 AND 1995 IS UNAUDITED)
    
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements comprise the accounts of
the Company and its continuing subsidiary companies. All intercompany
transactions have been eliminated.
 
  Principles of Translation
 
     Assets and liabilities of the Company's foreign subsidiaries are translated
by using year-end exchange rates and income statement items are translated at
average exchange rates for the year. Translation adjustments are accumulated in
a separate component of stockholders' equity.
 
  Inventories
 
     Materials and supplies are carried at the lower of average cost or
replacement cost. Finished goods and work-in process are carried at the lower of
average cost or net realizable value.
 
  Property and Equipment
 
     Property and equipment are carried at cost. Depreciation of owned equipment
is computed on a straight-line basis over the estimated useful lives of the
related assets, generally from three to ten years. Leasehold improvements are
amortized over the term of the related lease, generally from five to ten years,
which approximates the useful lives of these improvements. Equipment under
capital leases is amortized on a straight-line basis over the term of the lease,
generally four to ten years, which approximates the estimated useful lives of
the leased equipment.
 
  Per Share Data
 
   
     Income (loss) per share is computed by dividing net income (loss), less
preferred stock dividends, by the weighted average number of common and common
equivalent shares outstanding during the period. Common equivalent shares
consist of the dilutive effect, if any, of unissued shares under options and
warrants, computed using the treasury stock method (using the average stock
prices for primary basis and the higher of average or period-end stock prices
for fully diluted basis). Fully diluted income per share is computed assuming
the conversion of convertible preferred stock and subordinated debentures at the
beginning of the period or the date of issuance, whichever is later.
    
 
  Statement of Cash Flows
 
     For purposes of the Statement of Cash Flows, the Company considers all
highly liquid investments with an original maturity of three months or less to
be cash equivalents.
 
  Revenue Recognition
 
     The Company recognizes revenue on the percentage of completion method for
its research and development contracts with progress measured based on the ratio
of costs incurred to the total estimated cost, and generally, when product is
shipped for all other sales. Where the Company receives contracts for the design
and construction of specialty instruments that require long manufacturing times,
the Company will also
 
                                       F-7

                  BARRINGER TECHNOLOGIES INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
recognize revenue on the percentage of completion method similar to its
recognition method in the research and development business.
 
   
     For the year ended December 31, 1995, the Company had recognized revenues
of $264,000 on jobs in process and had incurred related costs of $183,000, of
which $210,000 were billed to customers at December 31, 1995. For the nine
months ended September 30, 1996, the Company had recognized revenues of $36,000
on jobs in process and had incurred costs of $52,000, of which none were billed
to customers at September 30, 1996.
    
 
  Financial Instruments and Credit Risk Concentration
 
     Financial instruments which potentially subject the Company to
concentrations of credit risk consist primarily of trade accounts receivable.
Concentrations of credit risk with respect to such receivables are limited
primarily to United States and Canadian governmental agencies.
 
  Long-Lived Assets
 
   
     Long-lived assets, such as property and equipment, are evaluated for
impairment when events or changes in circumstances indicate that the carrying
amount of the assets may not be recoverable through the estimated undiscounted
future cash flows from the use of these assets. When any such impairment exists,
the related assets will be written down to fair value. This policy is in
accordance with Statement of Financial Accounting Standards No. 121, "Accounting
for the Impairment of Long-Lived Assets and Long-Lived Assets to be Disposed
of ", which is effective for fiscal years beginning after December 15, 1995. No
write-downs have been necessary through September 30, 1996.
    
 
  Stock-Based Compensation
 
     The Company does not presently intend to adopt the fair value based method
for accounting for stock compensation plans as permitted by Statement of
Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation", which is effective for transactions entered into in fiscal years
that begin after December 15, 1995.
 
  Fair Value of Financial Instruments
 
     The carrying amounts reported in the consolidated balance sheets for cash
and cash equivalents, accounts receivable, accounts payable, and accrued
liabilities approximate fair value because of the immediate or short-term
maturity of these financial instruments.
 
  Unaudited Information
 
   
     The consolidated balance sheet of the Company as of September 30, 1996, the
consolidated statements of operations and cash flows for the nine months ended
September 30, 1996 and 1995, the consolidated statement of stockholders' equity
for the nine months ended September 30, 1996 and the notes to such financial
statements, are unaudited. However, in the opinion of management, such financial
statements contain all adjustments (consisting of only normal recurring
accruals) necessary for a fair presentation. The results of operations for the
interim periods are not necessarily indicative of the results to be expected for
the full year.
    
 
  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 reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the
 
                                       F-8

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from these estimates. Many of the Company's estimates and
assumptions used in the financial statements relate to the Company's products,
which are subject to technology and market changes. It is reasonably possible
that changes may occur in the near term that would affect management's estimates
with respect to inventories and equipment.
 
2. INVESTMENT IN UNCONSOLIDATED SUBSIDIARY
 
     During the first quarter of 1995, the Company began to seek a purchaser for
its then 47% interest in Barringer Laboratories, Inc. ("Labco"). Accordingly,
the financial statements have been reclassified, where appropriate, to reflect
Labco as an operation held for sale.
 
     Pursuant to the terms of a Stock Purchase Agreement, dated December 8, 1995
("Agreement"), by and between the Company and Labco, on December 13, 1995 the
Company sold to Labco 647,238 shares of Labco's common stock for an aggregate
purchase price of $809,000, resulting in a gain of $93,000. The purchase price
consisted of cancellation of all intercompany obligations and $300,000 in cash.
After giving effect to the sale of the Labco shares, the Company continued to
own 437,475 shares of Labco stock.
 
   
     Under the terms of the Agreement, all intercompany agreements between the
Company and Labco terminated and certain collateral securing the Company's
obligations thereunder was returned to the Company. However, pursuant to the
terms of the Agreement, Labco retained 88,260 shares of Labco stock owned by the
Company (the "Retained Shares"). In the event that Labco had met certain pre-tax
earnings goals for 1996, those shares would have been returned to the Company.
If Labco had not met such goals, all or a portion of such Retained Shares would
have been retained by Labco. The Company has reduced its gain by the value of
the Retained Shares.
    
 
     The Company also agreed to terminate all voting arrangements allowing it to
vote shares of Labco stock not owned by it and agreed for a period of 24 months
not to enter into any such voting arrangements. In addition, the Company granted
Labco the right, until January 2, 1997, to purchase shares of Labco stock owned
by the Company in the event that the Company wishes to sell any additional
shares. In connection with such right, the Company agreed to certain
restrictions on the transferability of any Labco stock owned until January 2,
1997.
 
   
     The right of first refusal and the related restrictions would have
terminated upon the first to occur of (a) the sale, within twelve months of the
date of the Agreement, of Labco stock sufficient to give any one person or
entity ownership of 50% or more of the Labco stock, or (b) the change of more
than three members of the Board of Directors of Labco, other than as a result of
resignation, during any twelve month period after the date of the Agreement.
    
 
     After the transaction described above, the Company retained a 26% ownership
interest in the common stock of Labco and is reporting its remaining interest in
Labco under the equity method of accounting.
 
     In October 1996, the Company and Labco entered into a Termination Agreement
(the "Termination Agreement") pursuant to which Labco agreed to waive its right
of first refusal and to terminate the restrictions on the transfer of the
Company's remaining Labco shares. The Company agreed that, for a period of three
months from the date of the Termination Agreement, it would sell such shares at
a price of at least $1.6875 per share (the "Target Price") in a distribution in
which it would not knowingly sell more than 75,000 shares to any one purchaser
or group of related purchasers. Under the Termination Agreement, for such three-
month period, the Company must sell its Labco shares as provided above if it
receives an offer to acquire such shares at a price per share at least equal to
the Target Price. The restrictions described above also apply to any shares of
Labco common stock issuable to the Company upon the exercise of certain warrants
held by the Company. Labco has registered the Company's Labco shares for resale
pursuant to the Securities Act to facilitate such sales.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
   
     As of November 11, 1996, the Company had sold 280,000 shares of Labco
common stock pursuant to the Termination Agreement.
    
 
     In the Termination Agreement, the Company and Labco agreed to surrender to
Labco the Retained Shares and to terminate all remaining inter-company
arrangements. In addition, upon the disposition by the Company of at least
250,000 of its shares of Labco common stock, Stanley S. Binder and John J. Harte
will resign their positions with Labco.
 
     The following are the condensed results of operations and condensed balance
sheet for Labco:

5. BANK INDEBTEDNESS, OTHER NOTES, ACCRUED LIABILITIES AND CONVERTIBLE
SUBORDINATED DEBENTURES
    
 
   
     The Company's Canadian subsidiary, Barringer Research Ltd. ("BRL"), has a
financing arrangement with the Ontario Development Corporation ("ODC") for a
$730,000 export line of credit. BRL may borrow up to $730,000 on a formula basis
of 90% of export accounts receivable plus 70% of the value of export purchase
orders (subject to a maximum sub-limit of $230,000). The rate of interest is
adjusted quarterly and was 10% at September 30, 1996. At September 30, 1996, BRL
had $373,000 available pursuant to the borrowing formula under this facility.
    
 
   
     BRL also has a line of credit financing arrangement with the
Toronto-Dominion Bank ("Bank") that provides up to $730,000 based on eligible
receivables. The rate of interest is Canadian prime plus 1.5% (7.25% at
September 30, 1996). At September 30, 1996, BRL had $227,000 available pursuant
to the borrowing formula under this facility. This facility is guaranteed by the
Company.
    
 
     Commencing in March 1995, BRL had not been in compliance with the
collateral coverage covenant of the loan agreement. The amount of funds borrowed
were in excess of the amount allowed pursuant to the collateral formula. At that
time, the Bank agreed to give BRL approximately six months to comply with this
formula. During this time, the Bank continued to finance BRL's needs. On
September 28, 1995, the Company entered into an agreement ("Agreement") with the
Bank, pursuant to which the Bank agreed that BRL would have until September 30,
1995 to comply with certain amended covenants specified in the Agreement and to
maintain such requirements thereafter. In exchange, the Company agreed to remit
50% of the net proceeds realized on the sale of a portion of its stock in Labco
(see Note 2) to BRL. In addition, the Company agreed to provide the Bank with
additional collateral to secure its advances to BRL, resulting in the pledge of
substantially all the assets of the Company as collateral. At September 30,
1995, BRL was in compliance with such covenants. However, at December 31, 1995
BRL was not in compliance with the minimum working capital requirement and at
January 31 and February 29, 1996 BRL's borrowings under the line of credit
exceeded the amount available thereunder. The Bank notified BRL of such
defaults, and without waiving any other remedies available to it, has charged
BRL an interest rate of 21% on the excess of such allowable borrowings. At June
30, 1996 BRL was not in compliance with the minimum working capital or the
minimum

net worth requirements. BRL was in compliance at September 30, 1996, although,
there can be no assurances that BRL will remain in compliance in the future.
Management believes that the Bank will continue to provide funding consistent
with past practices, however, the Company cannot predict what actions, if any,
the Bank may take or as to the timing thereof.

securities pursuant to which the Company receives net proceeds in an aggregate
amount in excess of $5,000,000, or (ii) July 9, 1997. Interest is payable

     As a result of the Company's history of losses, a valuation allowance has
been provided for all U.S. deferred tax assets and for substantially all of the
Canadian deferred tax assets. The net deferred tax asset relates to the
Company's Canadian subsidiary, which has available tax credits and loss
carryforwards. The Canadian subsidiary has a history of profitability, despite
the consolidated losses of the Company. Based on this history and estimated 1996
earnings, which includes earnings from certain contracts, as well as available
tax planning strategies, management considers realization of the unreserved
deferred tax asset more likely than not. During 1995 the Canadian subsidiary
realized tax loss carryforwards of approximately $75,000 with a tax benefit of
approximately $29,000. At September 30, 1996, the valuation allowance was
reduced by $160,000 as a result of changes in management's estimates of the
utilization of the Canadian tax loss carryforwards caused primarily by improved
operating results of BRL.

     The Company's Canadian subsidiary's defined benefit pension plan, which
covered its Canadian employees, was terminated at December 31, 1993. At the same
time, it established a money purchase plan that is structured after the 401(k)
salary deferral plan available to all U.S. employees and as such, does not
establish any corporate obligation other than a discretionary matching formula
to employee contributions. As a result of the termination, the Company
recognized a gain of $206,000, representing the excess of the Plan's projected
benefit obligation over the accumulated benefit obligation, in 1993 and
recognized an additional gain in 1995 of $172,000, representing the excess of
the Plan's assets over the cost of providing the annuities to the participants
for the value of their termination benefits. This excess will be put into a
money purchase contract

                                    PART II
 
                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 24. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Article Tenth of the Certificate of Incorporation, as amended (the
"Certificate of Incorporation"), and Section 10 of the Company's by-laws, as
amended ("By-laws"), provide that the Company shall, to the fullest extent
permitted by law, indemnify each person (including the heirs, executors,
administrators and other personal representatives of such person) against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement, actually and reasonably incurred by such person in connection with
any threatened, pending or actual suit, action or proceeding (whether civil,
criminal, administrative or investigative in nature or otherwise) in which such
person may be involved by reason of the fact that he or she is or was a director
or officer of the Company or is serving any other incorporated or unincorporated
enterprise in any of such capacities at the request of the Company.
 
     Section 145 of the General Corporation Law of the State of Delaware (the
"GCL") permits a corporation, under specified circumstances, to indemnify its
directors, officers, employees or agents against expenses (including attorney's
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by them in connection with any action, suit or proceeding brought by
third parties by reason of the fact that they were or are directors, officers,
employees or agents of the corporation, if such directors, officers, employees
or agents acted in good faith and in a manner they reasonably believed to be in
or not opposed to the best interests of the corporation and, with respect to any
criminal action or proceeding, had no reason to believe their conduct was
unlawful. In a derivative action, i.e., one by or in the right of the
corporation, indemnification may be made only for expenses actually and
reasonably incurred by directors, officers, employees or agents in connection
with the defense or settlement of an action or suit, and only with respect to a
matter as to which they shall have acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interests of the
corporation, except that no indemnification shall be made if such person shall
have been judged liable to the corporation unless and only to the extent that
the court in which the action or suit was brought shall determine upon
application that the defendant directors, officers, employees or agents are
fairly and reasonably entitled to indemnity for such expenses despite such
adjudication of liability.
 
     Article Tenth of the Certificate of Incorporation also contains a provision
limiting the personal liability of directors to the fullest extent permitted or
authorized by the GCL or other applicable law. Under the GCL, such provision
would not limit liability of a director for (i) breach of the director's duty of
loyalty, (ii) acts or omissions not in good faith or involving intentional
misconduct or knowing violation of law, (iii) payment of dividends or
repurchases or redemptions of stock other than from lawfully available funds, or
(iv) any transactions from which the director derives an improper benefit.

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES
 
     The following information relates to securities of the Company issued or

Act (all share and per share amounts have been adjusted to reflect the

(the "Common Stock") effected on September 25, 1995):
 
          (i) On July 10, 1996 the Company issued an aggregate amount of
     $1,000,000 of its 6% subordinated convertible debentures, due 1997 (the
     "Debentures") to institutional and private investors and members of
     management for an aggregate purchase price of $1,000,000. This transaction
     was completed without registration under the Securities Act of the
     Debentures or the shares of Common Stock into which such Debentures are
     convertible in reliance upon exemptions provided by Section 4(2) of the
     Securities Act. There were no underwriters for this issuance.
 
          (ii) On June 30, 1995 the Company issued an aggregate of 28 units,
     each unit consisting of 2,500 shares of Common Stock and a five-year
     warrant to purchase 2,500 shares of Common Stock at $2.00 per share (a
     "Unit"), to private investors and members of management, for an aggregate
     purchase price of $168,000. This transaction was completed without
     registration under the Securities Act of the shares of Common Stock or the
     warrants comprising the Units or the shares of Common Stock underlying the
     warrants in reliance upon the exemptions provided by Section 4(2) of the
     Securities Act. There were no underwriters for this issuance.
 
          (iii) On May 9, 1995 the Company issued an aggregate of 125 Units and
     one three-year warrant to purchase 37,500 shares of Common Stock at $2.00
     per share, to two institutional investors, for an aggregate purchase price
     of $750,000. This transaction was completed without registration under the
     Securities Act of the shares of Common Stock or the warrants comprising the
     Units, the shares of Common Stock underlying the warrants included in the
     Units, the additional three-year warrant or the shares of Common Stock
     underlying the three-year warrant, in reliance upon the exemptions provided
     by Section 4(2) of the Securities Act. There were no underwriters for this
     issuance.
 
          (iv) At various times between October 1993 and October 1996, the
     Company granted stock options to certain employees of the Company covering
     an aggregate of 434,375 shares of Common Stock. These grants were exempt
     from registration pursuant to Securities Act Release No. 33-6188 (Feb. 1,
     1980). No underwriter was involved in these grants.

ITEM 28. UNDERTAKINGS
    
 
     The undersigned registrant hereby undertakes:
 
          (1) For the purpose of determining any liability under the Securities
     Act, the information omitted from the form of Prospectus filed as part of
     this Registration Statement in reliance upon Rule 430A and contained in a
     form of Prospectus filed by the registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act, shall be deemed a part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purposes of determining any liability under the Securities
     Act, each post-effective amendment that contains a form of Prospectus shall
     be deemed to be a new registration statement relating to the securities
     offered therein, and the offering of such securities at that time shall be
     deemed to be the initial bona fide offering thereof.
 
          (3) 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 on
     indemnifications, or otherwise, the registrant has been advised that in the
     opinion of the Securities and Exchange Commission such indemnification is
     against public policy as expressed in the Securities Act and is, therefore,
     unenforceable. In the event that a claim for indemnification against such
     liabilities (other than the payment by the registrant of expenses incurred
     or paid by a director, officer or controlling person of the registrant in
     the successful defense of any action, suit or proceeding) is asserted by
     such director, officer or controlling person in connection with the
     securities being registered, the registrant will, unless in the opinion of
     its counsel the matter has been settled by controlling precedent, submit to
     a court of appropriate jurisdiction the question whether such
     indemnification by it is against public policy as expressed in the
     Securities Act and will be governed by the final adjudication of such
     issue.
