                               PROSPECTUS SUMMARY
    
 
     The following summary is qualified in its entirety by the more detailed
information and the consolidated financial statements and notes thereto
appearing elsewhere in this Prospectus, including the information under "Risk
Factors."
 
                                  THE COMPANY
 
   
     Barringer Technologies Inc. ("Barringer" or the "Company") is the world's
leading manufacturer (based on units sold) of high sensitivity equipment used
for detecting and identifying trace amounts of plastic and other explosives and
illegal drugs. The Company designs and produces products that employ a
proprietary application of ion mobility spectrometry ("IMS") technology that can
detect and identify targeted compounds in amounts smaller than one-billionth of
a gram in approximately six seconds. The Company's principal product, the
IONSCAN(R), is a portable desktop system. As of June 30, 1997, the Company had
sold over 500 units in 39 countries. The Company's revenues have grown from $2.0
million for the year ended December 31, 1991 to $10.9 million for the year ended
December 31, 1996, representing a compounded annual growth rate of 40.4% over
the last five years. For the six months ended June 30, 1997, the Company's
revenues and net income were $9.4 million and $2.3 million, respectively.
    
 
   
     The markets for the Company's IONSCAN(R) currently include aviation
security, other transport security, facilities protection, forensics, military,
corrections, customs and law enforcement. The Company's customers include the
Federal Aviation Administration (the "FAA"), the U.S. Coast Guard, the U.S. Drug
Enforcement Agency (the "DEA") and the Federal Bureau of Investigation (the
"FBI"), as well as customs agencies in France, Canada and Japan and various
prison facilities in the U.S. and elsewhere. The IONSCAN(R) is also installed at
over 40 airports and transportation centers throughout the world, including
Gatwick and Heathrow airports in the United Kingdom, John F. Kennedy
International Airport, certain European Passenger Service ("British Rail")
terminals and the Eurotunnel. The Company believes that its principal
competitive advantages are the detection capability, reliability, versatility,
cost effectiveness, ease of use and portability of the IONSCAN(R). These
advantages enable the IONSCAN(R) to be used both in lieu of and in conjunction
with bulk imaging technologies, such as enhanced x-ray and computer aided
tomography ("CATSCAN").
    
 
   
     The Company believes that many of the markets it serves are experiencing
substantial growth. Recently, growth in the markets for advanced explosives
detection technology has accelerated significantly, principally in reaction to
heightened safety concerns caused by the threat of terrorism. For example, in
October 1996, Congress appropriated $144 million for the procurement of advanced
explosives detection technology for aviation security. Terrorist attacks on bus
and train stations, the World Trade Center and the Alfred R. Murrah Federal
Building in Oklahoma City also have resulted in the deployment of advanced
explosives detection technology for other uses. In addition, according to the
U.S. Office of National Drug Control Policy, use of certain illegal drugs has
increased during the past five years. As a result of increased drug usage, a
heightened public awareness of drug-related criminal activity and the use of
more sophisticated techniques by drug traffickers, government agencies have
increasingly turned to advanced detection technology to assist in their drug
interdiction efforts.
    
 
   
     The Company markets its products through a direct sales organization
comprised of 18 sales people located at its headquarters in New Jersey and at
offices in Toronto, London, and Paris. In addition, the Company utilizes a
network of 49 independent sales and service representatives located in Europe,
the Middle East, Africa, Asia, South America and Australia.
    
 
     The Company's objective is to maintain its position as the world's leading
provider of trace detection systems in its core markets and to become a leading
supplier of other advanced technology security solutions. The Company intends to
achieve this objective by further penetrating its existing markets, leveraging
its IMS technology for new applications, pursuing strategic relationships and
acquisitions and expanding its sales and marketing capabilities.

                           FORWARD-LOOKING STATEMENTS
 
   
     This Prospectus contains forward-looking statements within the meaning of
Section 27A of the Securities Act and Section 21E of the Securities Exchange Act
of 1934, as amended (the "Exchange Act"). Such statements include, but are not
limited to, the anticipated growth in the demand for the Company's products, the
Company's opportunities to increase sales through, among other things, the
development of new applications of and markets for the IONSCAN(R) technology,
the development of new products, the probability of the Company's success in the
sale of IONSCAN(R)s in current or future markets, the potential effect of
government regulations and directives changing security requirements, the
ability of the IONSCAN(R) to satisfy any certification protocol adopted by the
FAA or any other government agency, the amount and timing of domestic and
foreign government appropriations for the development and deployment of advanced
detection technology, the Company's liquidity and capital requirements and the
Company's anticipated use of proceeds.
    
 
   
     Forward-looking statements are inherently subject to risks and
uncertainties, many of which cannot be predicted with accuracy and some of which
might not even be anticipated. Future events and actual results, financial and
otherwise, could differ materially from those set forth in or contemplated by
the forward-looking statements contained herein. Important factors that could
contribute to such differences are set forth below under "Risk Factors,"
including, but not limited to, "Dependence on and Effects of Government
Regulation and Procurement Policies," "Dependence on Large Orders; Customer
Concentrations," "Dependence on IONSCAN(R) and Market Acceptance," "Dependence
on New Product Development; Technological Advancement," "Limited Proprietary

                                  RISK FACTORS
 
     The Common Stock offered hereby involves a high degree of risk. In addition
to the other information contained in this Prospectus, the following risk
factors should be considered carefully in evaluating the Company, its business
and an investment in the Common Stock offered hereby.
 
DEPENDENCE ON AND EFFECTS OF GOVERNMENT REGULATION AND PROCUREMENT POLICIES
 
     The Company's business is dependent upon purchases of IONSCAN(R)s by
government agencies. Budgetary allocations for detection equipment are
dependent, in part, upon government policies that fluctuate from time to time in
response to political and other factors, including the public's perception of
the threat of airline bombings and other terrorist acts. Growth in the Company's
business is substantially dependent upon the adoption and implementation of
regulations or requirements in the aviation security market, particularly in the
United States, resulting in the use of advanced explosives detection systems,
including trace particle detection equipment. The Company expects that a
substantial portion of current and anticipated purchases of advanced detection
equipment in the aviation security market will be made by the FAA with
appropriated funds. In addition, growth in the Company's business will also be
dependent on continued government purchases of IONSCAN(R)s for drug interdiction
applications. A reduction of funding for security efforts or drug interdiction
could materially and adversely affect the Company's business, financial
condition and results of operations. There can be no assurance that funding for
the purchase of such equipment will be continued or as to the level of such
funding. A substantial amount of the funds appropriated to date have been and
amounts appropriated in the future will continue to be used to purchase
equipment utilizing other technologies, such as enhanced x-ray, CATSCAN and
other bulk imaging technologies. 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 Company's products
will meet any certification or other requirements that may be adopted by the FAA
or any other government agency. See "Business--Government Regulation."
 
                                        6
<PAGE>   8
 
DEPENDENCE ON LARGE ORDERS; CUSTOMER CONCENTRATIONS
 
     In any given fiscal year, the Company's revenues have principally
consisted, and the Company believes will continue to consist, of orders for
multiple IONSCAN(R)s from a limited number of customers. For example, during the
first half of 1997, the Company received large orders for its IONSCAN(R) from
the FAA and the U.S. Coast Guard. While the number and identity of the Company's
customers may vary from period to period, the Company is nevertheless dependent
upon these multiple orders for a substantial portion of its revenues. There can
be no assurance that the Company will obtain such multiple orders on a
consistent basis. During the first half of 1997, approximately $4.8 million, or
51.2%, of the Company's revenues were generated from sales to the Company's
three largest customers. During the fiscal year ended December 31, 1996,
revenues from the Company's three largest customers were approximately $4.3
million, or 39.3%, of the Company's revenues. The Company anticipates that a
significant portion of its future revenues will result from orders from the FAA.
The Company's inability to obtain sufficient multiple orders or to expand its
customer base could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
DEPENDENCE ON IONSCAN(R) AND MARKET ACCEPTANCE
 
     The Company derives substantially all of its revenues from the sale of
IONSCAN(R)s and its future profitability is substantially dependent on the
Company's ability to market the IONSCAN(R) successfully. There can be no
assurance that markets for IONSCAN(R) technology 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. See "Business--Sales and Marketing."
 
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 products that
incorporate technological advances, keep pace with evolving industry standards
and respond to changing customer requirements. 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, financial condition and results of operations would be materially and
adversely affected. See "Business--Sales and Marketing" and "--Product
Development."
 
   
     In addition, from time to time the Company or its present or potential
competitors may introduce new products, capabilities or technologies that have
the potential to replace, shorten the life spans of, or render obsolete the
Company's existing products. There can be no assurance that the Company will be
successful in convincing potential customers that the IONSCAN(R) is superior to
such other systems or products, that new systems with comparable or greater
performance, lower prices and faster or equivalent throughput will not be
introduced, or that, if such products are introduced, customers will not delay
or cancel existing or future orders for the IONSCAN(R). 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" and
"Business--Competition." Such delays could have a material adverse effect on the
Company's business, financial condition and results of operations.
    
 
LIMITED PROPRIETARY TECHNOLOGY
 
     Certain of the technology used in the IONSCAN(R) is licensed by the Company
from the Canadian government pursuant to a license agreement that expires in
March 1999, subject to the Company's right to extend on a year-to-year basis
through March 2009. While the Company holds patents relating to certain
components, systems and techniques used in the IONSCAN(R) and while certain
other elements of the IONSCAN(R) are protected by other intellectual property
rights, the Company has no
 
                                        7
<PAGE>   9
 
comprehensive patent or similar exclusive intellectual property right covering
the IONSCAN(R) in its entirety. In addition, the basic IMS technology used by
the Company is not proprietary and is available in the public domain.
Accordingly, present and potential competitors could use such basic technology
to duplicate the performance of the IONSCAN(R). See "Business--Competition" and
"--Patents, Trademarks and Proprietary Rights."
 
FLUCTUATIONS IN OPERATING RESULTS
 
     The Company's past operating results have been, and its future operating
results will be, subject to fluctuations resulting from a number of factors,
including: the timing and size of orders from, and shipments to, major
customers; budgeting and purchasing cycles of its customers; delays in product
shipments caused by customer requirements or the inability of customers to
accept shipments; the timing of enhancements to the IONSCAN(R) by the Company or
new products introduced by the Company or its competitors; changes in pricing
policies by the Company, its competitors or suppliers, including possible
decreases in average selling prices of the IONSCAN(R) in response to competitive
pressures; the proportion of revenues derived from competitive bid processes;
the mix between sales to domestic and international customers; market acceptance
of enhanced versions of the IONSCAN(R); the availability and cost of key
components; the availability of manufacturing capacity; and fluctuations in
general economic conditions. The Company also may choose to reduce prices or to
increase spending in response to competition or to pursue new market
opportunities, all of which may have a material adverse effect on the Company's
business, financial condition and results of operations. The Company's revenues
in any period are derived from sales of IONSCAN(R)s to a limited number of
customers and are generally recognized upon shipment. As a result, variations in
the number of orders or the timing of shipments may cause the Company's
quarterly and annual operating results to vary substantially. See "-- Dependence
on Large Orders; Customer Concentrations" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Quarterly Results of
Operations."
 
   
     Moreover, government agencies and certain 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. Because the Company generally
recognizes substantially all of the revenue from a sale upon shipment, and
because 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 and the
predictability of such quarterly results.
    
 
COMPETITION
 
     The Company competes with other entities, including Thermedics Detection
Inc., InVision Technologies, Inc. and Vivid Technologies, Inc., 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. There can be no assurance that the Company will be able to continue to
compete successfully with its competitors or be able to compete with new market
entrants or in new markets that may develop.
 
   
     The Company competes for government expenditures with equipment
manufacturers utilizing other types of detection technologies, including
enhanced x-ray, CATSCAN and other bulk imaging technologies, as well as with
manufacturers of other IMS equipment and manufacturers using other trace
particle detection technologies, such as gas chromatography and
chemiluminescence.
    
 
     The Company also competes with the use of canines to locate the presence of
explosives or drugs.
 
     As a result of recent government initiatives, the Company anticipates that
additional technologies, including improved IMS technologies, will be developed
and that new competitors will enter the
 
                                        8
<PAGE>   10
 
Company's markets. The failure of the Company to develop improvements or
otherwise successfully compete in its markets would have a material adverse
effect on the Company's business, financial condition and results of operations.
See "--Dependence on and Effects of Government Regulation and Procurement
Policies" and "Business--Competition."
 
LENGTHY SALES CYCLE
 
     The Company's sales process is often protracted due to the lengthy approval
processes that typically accompany government expenditures. Typically, six to 12
months may elapse between a new customer's initial evaluation of the IONSCAN(R)
and the execution of a contract. See "--Fluctuations in Operating Results,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Overview" and "--Quarterly Results of Operations."
 
INTERNATIONAL BUSINESS; RISK OF CHANGE IN FOREIGN REGULATIONS; FLUCTUATIONS IN
EXCHANGE RATES
 
     The Company markets its products to customers outside of the U.S. and,
accordingly, is exposed to the risks of international business operations,
including unexpected changes in foreign and domestic regulatory requirements,
possible foreign currency controls, uncertain ability to protect and utilize its
intellectual property in foreign jurisdictions, currency exchange rate
fluctuations or devaluations, tariffs or other barriers, difficulties in
staffing and managing foreign operations, difficulties in obtaining and managing
vendors and distributors and potentially negative tax consequences.
International sales are subject to certain inherent risks including embargoes
and other trade barriers, staffing and operating foreign sales and service
operations and collecting accounts receivable. The Company is also subject to
risks associated with regulations relating to the import and export of high
technology products. The Company cannot predict whether quotas, duties, taxes or
other charges or restrictions upon the importation or exportation of the
Company's products in the future will be implemented by the U.S. or any other
country. There can be no assurance that any of these factors will not have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
     A portion of the Company's revenues and expenses are denominated in foreign
currencies. Fluctuations in currency exchange rates could adversely affect the
Company's profitability and could cause the Company's products to become
relatively more expensive to customers in a particular country, leading to fewer
sales or reduced selling prices in that country. As a result, the Company is
exposed to a certain degree of exchange rate risk. The Company generally does
not hedge its foreign exchange exposure. There can be no assurance that the
Company will not experience material losses in the future as a result of
currency fluctuations or that any such losses will not have a material adverse
effect on the Company's business, financial condition and results of operations.
See "Management's Discussion and Analysis of Financial Condition and Results of
Operations--Overview."
 
DEPENDENCE ON LIMITED NUMBER OF SUPPLIERS
 
   
     Certain key components used in the Company's products have been designed by
the Company to its specifications and are currently purchased from only one or a
limited number of suppliers. The Company currently does not have long-term
agreements with these suppliers. Moreover, in view of the high cost of many of
these components, the Company does not maintain significant inventories of some
necessary components. Recently, the Company has significantly increased its
purchases of certain components to meet expected demand for the IONSCAN(R). As a
result, in certain circumstances, the Company has had to enter into new supply
relationships in order to satisfy its increased demand for components and may be
required to do so in the future. If the Company's suppliers were to experience
financial, operational, production or quality assurance difficulties, the supply
of components to the Company would be reduced or interrupted. In the event that
a supplier were to cease operations, discontinue production of a component or
withhold supply for any reason, the Company might be unable to acquire certain
components from alternative sources, to find alternative third-party
manufacturers or sub-assemblers, or to obtain sufficient quantities of certain
components, which could result in delays or interruptions in product shipments,
and could have a material adverse effect on the Company's business, financial
condition and results of operations. See "Business--Manufacturing and Assembly."
    
 
                                        9
<PAGE>   11
 
ABILITY TO MANAGE RAPID GROWTH
 
     The Company has rapidly expanded its business operations as a result of
increased demand for the IONSCAN(R), which has placed significant demands on the
Company's manufacturing, management and working capital resources and operating,
management and financial control systems. Failure to maintain needed resources
or to enhance the Company's operating, management and financial control systems
as and when necessary, or difficulties encountered during such enhancements,
could have a material adverse effect on the Company's business, financial
condition and results of operations. The Company's future growth also will
depend on its ability to continue to improve and expand its engineering and
technical resources and to attract, retain and motivate key personnel. The
failure of the Company to increase its revenues sufficiently to compensate for
increased expenses resulting from current or future expansion, or the Company's
failure to otherwise adequately manage the growth of its business, would have a
material adverse effect on the Company's business, financial condition and
results of operations.
 
HISTORY OF LOSSES; CASH CONSTRAINTS
 
     The Company sustained net losses of $2.6 million and $827,000 for the years
ended December 31, 1994 and 1995, respectively, and had an accumulated deficit
of $12.3 million at June 30, 1997. Although the Company generated net income of
$2.1 million and $2.3 million for the year ended December 31, 1996 and the six
months ended June 30, 1997, respectively, the Company used $1.4 million and $1.3
million, respectively, of cash in operations during such periods as a result of
the need for working capital to support higher levels of accounts receivable and
inventory. The Company's failure to generate positive operating cash flow or to
maintain other sources of working capital could result in significant cash
shortages that could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
RISKS ASSOCIATED WITH POTENTIAL ACQUISITIONS
 
     An element of the Company's strategy is to review acquisition prospects
that would complement the Company's existing product offerings, augment its
market coverage, enhance its technological capabilities or otherwise offer
growth opportunities. Although the Company has no present understandings,
commitments or agreements with respect to any material acquisition of any
business, products or technologies, the Company may make such acquisitions in
the future. Future acquisitions by the Company could result in potentially
dilutive issuances of equity securities, the incurrence of debt and contingent
liabilities, and amortization expenses relating to goodwill and other intangible
assets, any of which could materially and adversely affect the Company's
business, financial condition and results of operations. Acquisitions entail
numerous risks, including difficulties in the assimilation of acquired
businesses, products and technologies, diversion of management's attention from
other business concerns, risks of entering markets in which the Company has no
or limited prior experience and potential loss of key employees of acquired
organizations. The Company's management has limited experience in assimilating
acquired organizations. No assurance can be given as to the ability of the
Company to integrate successfully any businesses, products, technologies or
personnel that might be acquired in the future, and the failure of the Company
to do so could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
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.
 
                                       10
<PAGE>   12
 
WARRANTY CLAIMS
 
     The Company generally provides a one-year parts and labor warranty on each
IONSCAN(R), although from time to time the Company has provided extended
warranties. 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. Increased warranty claims could have a material
adverse effect on the Company's business, financial condition and results of
operations.
 
POTENTIAL PRODUCT LIABILITY INSURANCE LIMITS
 
     The Company currently maintains product liability insurance in the amount
of $5.0 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. The Company believes that, as it
distributes more products into the marketplace and expands its product lines,
its exposure to potential product liability claims and litigation 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 its
existing coverage or obtain additional coverage at commercially reasonable
rates. Product liability losses in excess of insurance coverage could have a
material adverse effect on the Company's business, financial condition and
results of operations.

Stock are issuable upon the exercise or conversion of outstanding stock options,
warrants and convertible securities, 1,346,649 of which have been registered for
resale by the holders thereof and are, therefore, freely tradable and the
balance of which are subject to registration rights pursuant to which the
holders thereof can cause the Company to effect the registration of such shares
for resale.
    
 
   
     The Company cannot 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. Sales in the public market of
substantial amounts of Common Stock (including shares issued upon the exercise
or conversion of outstanding options, warrants and convertible securities), or
the perception that such sales might occur, could adversely affect prevailing
market prices for the Common Stock. 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 holders of an
aggregate of 770,297 shares of Common Stock (including 555,250 shares issuable
upon the exercise or conversion of outstanding options, warrants and convertible
securities), have agreed with the Underwriters not to offer or sell, directly or
indirectly, or otherwise reduce their risk in, any securities of the Company,
other than pursuant to the exercise of the Underwriters' over-allotment option,
for a period of 90 days after the date of this Prospectus, subject to certain
exceptions, without the prior written consent of Robertson, Stephens & Company.
See "Shares Eligible For Future Sale."
    
 
UNALLOCATED PROCEEDS OF OFFERING
 
     A significant portion of the estimated net proceeds of this Offering has
not been designated for specific uses. Accordingly, management of the Company
will have broad discretion with respect to the use of these funds. See "Use of
Proceeds."

VOLATILITY OF COMMON STOCK PRICE
 
     Prior to this 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 this Offering. See
"Price Range of Common Stock."
 
CERTAIN CHARTER PROVISIONS
 
     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 80.0% 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 10.0% 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 2,000,000 shares of
Common Stock offered hereby (2,218,000 if the Underwriters' over-allotment
option is exercised in full), at an assumed public offering price of $13.00 per
share and after deducting underwriting discounts and commissions and estimated
offering expenses payable by the Company, are estimated to be $24.1 million
($26.8 million if the Underwriters' over-allotment option is exercised in full).
The Company expects to use the net proceeds to increase its sales, marketing and
customer support capabilities, to expand its facilities, to pursue possible
acquisitions of, or investments in, complementary businesses, products or
technologies and for general corporate purposes. From time to time, the Company
evaluates potential acquisitions of such businesses, products or technologies in
the ordinary course of business. The Company has no present understandings,
commitments or agreements with respect to any material acquisitions of, or
investments in, any such businesses, products or technologies. See "Risk
Factors--Risks Associated with Potential Acquisitions."
    
 
     Pending the foregoing uses, the Company intends to invest the net proceeds
from this Offering in short-term, interest bearing, investment-grade securities.
 
                          PRICE RANGE OF COMMON STOCK
 
   
     Since November 12, 1996, the Common Stock has been included in the Nasdaq

                                DIVIDEND POLICY
 
     The Company has never declared or paid cash dividends on its Common Stock.
The Board of Directors 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
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 its Class A Convertible Preferred Stock and Class B
Convertible Preferred Stock at an annual rate of $0.16 per share, which
dividends, at the option of the Company, are payable in cash or shares of Common
Stock. See "Description of Capital Stock."

the Company on a basis consistent with the Company's audited consolidated
financial statements and, in the opinion of management, include all adjustments,
consisting only of normal recurring accruals, necessary for a fair presentation
of the Company's results of operations for such periods and financial condition

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
   
     Barringer is the world's leading manufacturer (based on units sold) of high
sensitivity equipment used for detecting and identifying trace amounts of
plastic and other explosives and illegal drugs. The markets for the Company's
IONSCAN(R) currently include aviation security, other transport security,
facilities protection, forensics, military, corrections, customs and law
enforcement. The Company sold its first IONSCAN(R) in 1990 and, as of June 30,
1997, had sold over 500 units. From 1991 to 1995, the Company incurred losses as
its business continued to develop, except during 1993 when the Company received
a significant order for IONSCAN(R)s for deployment at the Eurotunnel. In 1996,
the Company achieved profitability principally as a result of increased demand
for and favorable market acceptance of the IONSCAN(R). Prior to 1996, the
Company sold most of its IONSCAN(R)s for use in drug interdiction applications.
However, in 1996, the Company's unit sales were more evenly distributed between
explosives detection and drug interdiction applications. During the six months
ended June 30, 1997, approximately half of the Company's unit sales were for
explosives detection applications in the aviation security market. Management
expects that the aviation security market will continue to account for a
substantial portion of the Company's future revenues.
    
 
   
     Revenues consist of (i) sales of IONSCAN(R)s, related accessories and
consumable supplies, maintenance, training, and billable repairs, (ii) sales of
other instruments and (iii) funded product development grants and contracts. For
the year ended December 31, 1996 and the six months ended June 30, 1997,
approximately 86.1% and 95.6%, respectively, of the Company's consolidated
revenues were derived from the sale and servicing of IONSCAN(R)s. Selling prices
for the IONSCAN(R) average between $50,000 and $95,000 per unit, depending
principally on the configuration of the unit and the purchaser's location.
Profitability associated with any given sale, and the Company's gross margin for
any given quarter, may vary substantially due to unit configuration, the
geographic location of the purchaser and whether sales prices include a
distributor mark-up. 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 of operations. See "Risk Factors--Dependence on
Large Orders; Customer Concentrations" and "--Fluctuations in Operating
Results."
    
 
   
     Substantially all of the Company's revenues are denominated in U.S.
dollars. However, the Company operates in several foreign countries, including
Canada, the United Kingdom and France and, in those instances, the Company
recognizes revenues and incurs expenses denominated in the local currency. To
date, the Company has not experienced significant losses as a result of foreign
currency fluctuations. The Company generally does not hedge its foreign currency
exposure. Approximately 59.3% and 68.6% of the Company's total revenues for the
six months ended June 30, 1997 and the year ended December 31, 1996,
respectively, were derived from non-U.S. sources. Approximately 25.0% of total
revenues in 1996 were derived from customers in Canada. See "Risk
Factors--International Business; Risk of Change in Foreign Regulations;
Fluctuations in Exchange Rates."
    
 
   
     The Company manufactures to a sales forecast in order to have inventory
available to meet anticipated demand promptly and historically has not had a
backlog of orders. 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, the effects of competition and the complexity
of the customer's procurement process. However, as a result of large orders
received from the FAA and the U.S. Coast Guard in the second quarter of 1997,
the Company had a backlog of orders at June 30, 1997. See "Business--Backlog."

COMPARISON OF THE SIX-MONTH PERIOD ENDED JUNE 30, 1997 TO THE SIX-MONTH PERIOD
ENDED JUNE 30, 1996
 
     Revenues.  For the six months ended June 30, 1997, revenues increased by
$4.4 million, or 88.3%, to $9.4 million from $5.0 million in the comparable
period ended June 30, 1996. Sales of IONSCAN(R)s and related products increased
by $5.2 million, or 135%, due to an increase of 167% in the number of units
sold, offset in part by a decline in average unit selling price. The increase in
unit sales was due to significant IONSCAN(R) sales to the aviation security
sector, primarily to the FAA, and, to a lesser extent, increased sales in other
markets. The decrease in average selling prices resulted primarily from an
increase in the number of IONSCAN(R)s sold to U.S. government agencies, which
typically are at lower unit prices than sales to other customers. Sales of
specialty instruments decreased by approximately $523,000, or 83.9%, in the six
months ended June 30, 1997 as compared to the same period in 1996, principally
due to the completion of a heavy water analyzer contract, which was awarded to
the Company in mid-1995 and completed in the first half of 1996. Revenues
derived from funded research and development decreased by approximately
$227,000, or 42.0%, in the six months ended June 30, 1997 as compared to the
same period in 1996. Funded research revenues declined as the Company redirected
its research and development resources to product application and development
and in support of increased production. As sales of its IONSCAN(R)s have
increased, the Company has placed less emphasis on marketing of specialty
instruments and contract research and development. As a result, management
anticipates that revenues from those activities will become increasingly less
important to the Company's overall results of operations.
 
     Gross Profit.  For the six months ended June 30, 1997, gross profit
increased by $3.1 million, or 132%, to $5.5 million from $2.4 million in the
comparable 1996 period. As a percentage of revenues, gross profit increased to
58.1% in the 1997 period from 47.2% in the comparable 1996 period. The
improvement was primarily attributable to higher margins on international sales,
coupled with larger,
 
                                       17
<PAGE>   19
 
more efficient production runs of the IONSCAN(R), offset in part by lower
margins on sales to U.S. government agencies. In addition, the Company has been
able to reduce its cost of materials as a result of higher volume purchases.
 
     Selling, General and Administrative.  For the six months ended June 30,
1997, selling, general and administrative expenses increased by $1.6 million, or
95.0%, to $3.2 million from $1.6 million in the comparable 1996 period. Selling
and marketing expenses increased by approximately $1.0 million, of which
$687,000 was due to increased sales commissions attributable to a larger
percentage of sales originating through independent sales agents and
distributors during the period. The remaining increase was attributable to the
addition of sales and service personnel and related costs to handle increased
business volume. General and administrative expenses increased by $553,000,
primarily as a result of increased payroll and related costs and increased
professional and consulting costs. As a percentage of revenues, selling, general
and administrative expenses increased to 33.9% in the 1997 period from 32.8% in
the comparable 1996 period.
 
   
     Product Development.  For the six months ended June 30, 1997, product
development expenses increased by $281,000, or 493%, to $338,000 from $57,000 in
the comparable 1996 period. As a percentage of revenues, product development
expenses increased to 3.6% (6.9% when combined with funded research and
development) in the 1997 period from 1.1% (11.9% when combined with funded
research and development) in the comparable 1996 period as a result of a higher
level of internally funded new product development activity. Management expects
to incur increased product development expenses in future periods in connection
with the enhancement of existing products and the development of new products
and applications.
    
 
     Other Income and Expense.  For the six months ended June 30, 1997, interest
expense decreased by $125,000, or 96.2%, to $5,000 from $130,000 in the
comparable 1996 period as a result of the repayment of indebtedness out of the
net proceeds of the Company's November 1996 public offering.
 
     Investment income for the six months ended June 30, 1997 was $212,000 as
compared to $42,000 for the same period in 1996, primarily as a result of the
investment of a portion of the net proceeds from the Company's November 1996
public offering. In the six months ended June 30, 1996, the Company recorded
$42,000 of gains recognized on trading securities held for Canadian pension
funding purposes.
 
     Income Taxes.  In the six-month period ended June 30, 1997, the Company had
a net tax benefit of $131,000, composed of current foreign taxes of $291,000,
offset by a $422,000 net deferred tax benefit. Such deferred tax benefit was due
in part to a reduction in the deferred tax valuation allowance as a result of
changes in management's estimates of the utilization of both U.S. and Canadian
tax loss carryforwards caused primarily by improved operating results.
Management anticipates that further deferred tax benefits will be recognized in
1997.
 
COMPARISON OF THE FISCAL YEAR ENDED DECEMBER 31, 1996 TO THE FISCAL YEAR ENDED
DECEMBER 31, 1995
 
   
     Revenues.  Revenues for the fiscal year ended December 31, 1996 increased
by $4.5 million, or 71.4%, to $10.9 million from $6.4 million for the fiscal
year ended December 31, 1995. Net sales of the IONSCAN(R) and related products
increased by approximately $4.9 million, or 93.5%, due to an increase of 134% in
the number of units sold offset in part by a decline in average unit selling
price. The increase in unit sales was due to increased sales of the Model 400
which was introduced in the first quarter of 1995. The decrease in average
selling prices resulted from increased sales of the Model 400 which had a lower
average selling price than the Model 350. Net sales of other instruments
increased by approximately $223,000, or 41.6%, in 1996 as compared to 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 $349,000, or 33.2%, in 1996 as compared to
    
 
                                       18
<PAGE>   20
 
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.  Gross profit increased by $2.8 million, or 101%, to $5.6
million from $2.8 million for fiscal 1995. As a percentage of revenues, gross
profit increased to 50.9% from 43.5%. 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. 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 contributed to the
improvement.
    
 
     Selling, General and Administrative.  Selling, general and administrative
expenses increased by approximately $429,000, or 13.0%, to $3.7 million from
$3.3 million for fiscal 1995. In 1995, the Company recognized an expense
decrease of $337,000 attributable to a negotiated reduction in professional fees
and $147,000 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 1996 decreased by
$55,000, or 1.7%. As a percentage of revenues, selling, general and
administrative expenses decreased to 34.2% from 51.9%. The decrease as a
percentage of revenues was primarily attributable to spreading costs over
increased revenues. Selling expenses increased by $108,000, or 4.6%, in 1996 as
compared to 1995, primarily as a result of increased sales commissions on units
sold in the fourth quarter of 1996.
 
     Product Development.  Product development expenses decreased by
approximately $124,000, or 35.0%, to approximately $230,000 from $354,000 for
fiscal 1995. As a percentage of revenues, product development expenses decreased
to 2.1% from 5.5%. The level of product development at any time is primarily a
function of the availability of financial and personnel resources. Management
expects product development expenses to increase significantly in 1997.
 
     Other Income and Expense.  Equity in earnings of Labco represents the
Company's share of Labco's operating results, in which the Company had a
non-controlling ownership during most of 1996. Prior to December 31, 1995, the
Company had a controlling interest in Labco, but from the first quarter of 1995
until the end of 1996, the Company presented Labco as an operation held for
sale. The Company's share of Labco's net income for 1996 was $117,000, as
compared to $258,000 for the same period in 1995 (where it is shown as Income
from operations under the caption "Operation held for sale"). The Company sold
its remaining interest in Labco in 1996. See "Certain Transactions--Sale of
Subsidiary."
 
     In 1996, the Company earned investment income of $72,000.
 
     Other expense, net of income, was $12,000 in 1996, as compared to $52,000
in 1995. In 1996, the Company recognized $44,000 of gains from trading
securities held for Canadian pension funding purposes, partially offset by
miscellaneous expenses, including $43,000 of foreign exchange losses realized in
1996. In 1995, the Company realized foreign exchange losses of $79,000.
 
     Income Taxes.  For the year ended December 31, 1996, the Company had a net
tax benefit of $391,000 primarily due to a reduction in the deferred tax
valuation allowance as a result of changes in management's estimates of the
utilization of both U.S. and Canadian tax loss carryforwards caused primarily by
improved operating results. Management anticipates that further deferred tax
benefits will be recognized in 1997.
 
COMPARISON OF THE FISCAL YEAR ENDED DECEMBER 31, 1995 TO THE FISCAL YEAR ENDED
DECEMBER 31, 1994
 
     Revenues.  Revenues for the fiscal year ended December 31, 1995 increased
by $860,000, or 15.6%, to $6.4 million from $5.5 million for the fiscal year
ended December 31, 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
 
                                       19
<PAGE>   21
 
quarter of 1995. This reduction in selling price, coupled with other
improvements of the new model, contributed to a 36.6% increase in unit sales.
 
     Sales of instruments other than IONSCAN(R) products increased in 1995 by
approximately $114,000, or 33.0%, 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%, in 1995 as compared to 1994. The improved
revenues 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 DrugAlert(TM) were not significant.
 
   
     Gross Profit.  Gross profit increased by $1.4 million, or 96.1%, to $2.8
million from $1.4 million for fiscal 1994. As a percentage of sales, gross
profit increased to 43.5% from 25.6%. As a percentage of sales, gross profit for
the research and development business decreased to 5.1% from 12.1%. The decrease
was due to lower margins on 1995 contracts. As a percentage of sales, gross
profit for the instruments business increased to 53.1% from 26.4%. The 1995
gross profit was impacted by the write down in 1994 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.  Selling, general and administrative
expenses decreased by approximately $47,000, or 1.4%, to $3.3 million from $3.4
million for fiscal 1994. As a percentage of revenues, selling, general and
administrative expenses decreased to 51.9% from 60.8%. 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 as compared to 1994. 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, or 45.3%, in 1995 as compared to 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.
 
     Product Development.  Product development expenses decreased by
approximately $177,000, or 33.3%, to $354,000 from $531,000 in fiscal 1994. As a
percentage of revenue, product development expenses decreased to 5.5% from 9.6%.
The 1994 level was attributable to the completion of the development of the
Company's new Model 400.
 
     Other Income and Expense.  Interest expense increased by approximately
$38,000, or 18.8%, in 1995 as compared to 1994. The increase resulted from
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 changes in exchange rates
which generated a gain of $135,000 in 1994 compared to a loss of $79,000 in
1995.

LIQUIDITY AND CAPITAL RESOURCES
 
     During 1995 and 1996, the Company used the net proceeds of private and
public sales of securities to fund a portion of its cash flow needs. Since
January 1, 1995, the Company has raised approximately $2.0 million from the
private sales of warrants, convertible debentures and Common Stock. During 1995
and 1996, the Company also financed a portion of its working capital needs
through the sale of its remaining interest in Labco, pursuant to which the
Company received $874,000. See "Certain Transactions--Sale of Subsidiary." In
November 1996, the Company completed a public offering of its Common Stock and
Common Stock Purchase Warrants, resulting in net proceeds of $10.4 million. A
portion of the net proceeds of that offering was used to repay the Company's
long-term indebtedness.
 
     Cash used in operations was $1.3 million for the first six months of 1997,
$1.4 million in 1996 and $711,000 in 1995. Cash used in the first six months of
1997 resulted primarily from a significant increase in accounts receivable and
inventories, which more than offset net income of $2.3 million. Accounts
receivable increased as a result of higher sales, particularly during the month
of June. Inventories also increased substantially as the Company acquired the
materials necessary to support increased IONSCAN(R) production during the second
half of 1997. Cash used in operating activities during 1996 resulted primarily
from increases in accounts receivable and inventory, which more than offset net
income of $2.1 million for the year. Cash used in operating activities during
1995 resulted primarily from the loss of $827,000 recorded by the Company for
1995.
 
     Net cash used in investing activities was $240,000 for the first six months
of 1997, $3.9 million in 1996 and $58,000 in 1995. Cash used in investing
activities during the first half of 1997 resulted primarily from capital
expenditures of $513,000, offset in part by the sale of investments. Cash used
in investing activities during 1996 resulted primarily from the investment of a
portion of the net proceeds of the Company's November 1996 public offering,
offset in part by the receipt of $574,000 in connection with the Company's sale
of its remaining interest in Labco. Cash used in investing activities during
1995 resulted primarily from the purchase of equipment, which was partially
offset by the receipt of an additional $300,000 in connection with the Labco
sale.
 
     Cash provided by financing activities was $155,000 for the first six months
of 1997, $10.6 million in 1996 and $584,000 in 1995. Cash provided by financing
activities during the first six months of 1997 resulted primarily from the net
proceeds of certain option and warrant exercises, offset in part by the
repayment of indebtedness. Cash provided by financing activities in 1996
resulted primarily from the Company's November 1996 public offering, as well as
the conversion of $1.0 million of convertible subordinated debentures, offset in
part by the repayment of indebtedness. Cash provided by financing activities in
1995 resulted primarily from the receipt of net proceeds from the private
placement of securities, offset in part by the repayment of certain
indebtedness.
 
     The Company's capital expenditures for the six months ended June 30, 1997
aggregated $513,000. Such expenditures consisted primarily of software upgrades
to various manufacturing information systems, computer hardware modernization
relating to the Company's network system and the acquisition of additional
equipment. The Company anticipates that total capital expenditures will be
approximately $500,000 for the remainder of 1997, substantially all of which
will relate to equipment. Also, the Company believes that it will require
approximately $1.0 million in additional investment in tooling, equipment,
fixtures and facility to meet its anticipated production levels for 1998.
 
     The Company has substantial tax loss carryforwards to offset future tax
liabilities in the U.S.
 
     As of June 30, 1997, the Company had cash and cash equivalents of $3.9
million and marketable securities of $4.1 million. The Company believes that its
existing cash balances, marketable securities, income from operations in future
periods and the net proceeds of this Offering will be sufficient to fund its
working capital requirements for at least the next twelve months.

INFLATION
 
     Inflation was not a material factor in either the sales or the operating
expenses of the Company during the periods presented herein.
 
RECENT PRONOUNCEMENTS OF THE FINANCIAL ACCOUNTING STANDARDS BOARD
 
     In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS
128") which establishes standards for computing and presenting earnings per
share. SFAS 128 replaces the presentation of primary earnings per share and
fully diluted earnings per share with basic earnings per share and diluted
earnings per share, respectively. Basic earnings per share excludes dilution and
is computed by dividing income available to common stockholders by the weighted
average number of common shares outstanding for the period. Diluted earnings per
share is computed similarly to fully diluted earnings per share. The standard is
effective for financial statements for periods ending after December 15, 1997,
with earlier application not permitted.
 
     Basic and diluted earnings per share using this standard would have been
$0.26 and $0.22 and $0.42 and $0.35, respectively, for the three months and six
months ended June 30, 1997, respectively, and $0.10 and $0.10 and $0.16 and
$0.15, respectively, for the three months and six months ended June 30, 1996,
respectively.
 
     In June 1997, the FASB issued Statement of Financial Accounting Standards
No. 131, "Disclosures about Segments of an Enterprise and Related Information,"
which requires disclosure of reportable operating segments and will be effective
for financial statements issued for fiscal years beginning after December 31,
1997. The Company will be reviewing this pronouncement to determine its
applicability to the Company, if any.

                                    BUSINESS
 
OVERVIEW
 
   
     Barringer is the world's leading manufacturer (based on units sold) of high
sensitivity equipment used for detecting and identifying trace amounts of
plastic and other explosives and illegal drugs. The Company designs and produces
products that employ a proprietary application of ion mobility spectrometry
("IMS") technology that can detect and identify targeted compounds in amounts
smaller than one-billionth of a gram in approximately six seconds. The Company's
principal product, the IONSCAN(R), is a portable desktop system. As of June 30,
1997, the Company had sold over 500 units in 39 countries. The Company's
revenues have grown from $2.0 million for the year ended December 31, 1991 to
$10.9 million for the year ended December 31, 1996, representing a compounded
annual growth rate of 40.4% over the last five years. For the six months ended
June 30, 1997, the Company's revenues and net income were $9.4 million and $2.3
million, respectively.
    
 
   
     The markets for the Company's IONSCAN(R) currently include aviation
security, other transport security, facilities protection, forensics, military,
corrections, customs and law enforcement. The Company's customers include the
FAA, the U.S. Coast Guard, the DEA and the FBI, as well as customs agencies in
France, Canada and Japan and various prison facilities in the U.S. and
elsewhere. The IONSCAN(R) is also installed at over 40 airports and
transportation centers throughout the world, including Gatwick and Heathrow
airports in the United Kingdom, John F. Kennedy International Airport, certain
British Rail terminals and the Eurotunnel. The Company believes that its
principal competitive advantages are the detection capability, reliability, cost
effectiveness, versatility, ease of use and portability of the IONSCAN(R). These
advantages enable the IONSCAN(R) to be used both in lieu of and in conjunction
with bulk imaging technologies, such as enhanced x-ray and CATSCAN.
    
 
INDUSTRY BACKGROUND
 
     The Company believes that there are numerous potential applications for its
trace detection technology. Currently, the principal applications are explosives
detection and drug interdiction.
 
     Explosives Detection
 
   
     In the past several years, a number of events have contributed to increased
public concern regarding the threat of terrorism and have focused government
attention on the limited effectiveness of currently deployed x-ray and metal
detection equipment and on the need for advanced explosives detection
technology. As a result, several advanced technologies have been adapted for use
in explosives detection applications. These technologies include bulk imaging
techniques, such as enhanced x-ray and CATSCAN, as well as trace detection
techniques, such as IMS, gas chromatography and chemiluminescence. Bulk imaging
techniques offer certain advantages over conventional x-ray technology, but are
generally expensive to deploy (as much as $1.0 million per installation), are
non-portable and generally reject a large number of objects as a result of
perceived anomalies that are later determined not to be explosives. By
comparison, trace detection equipment is capable of detecting and identifying
minute amounts of chemical substances and is generally more portable and less
expensive than bulk imaging equipment.
    
 
   
     While implementation of advanced detection strategies has varied
significantly around the world, the Company believes that aviation authorities,
including the FAA and BAA plc, formerly the British Airport Authority (the
"BAA"), have generally recognized that no one detection technology provides a
complete solution to the problem of enhancing existing detection capabilities.
Consequently, trace detection technology is frequently deployed as a complement
to bulk imaging equipment to resolve anomalies identified by bulk detectors and
in applications where it is impractical to use the larger, less mobile bulk
imaging detectors, such as checking carry-on baggage. Trace detection technology
is also deployed in lieu of bulk imaging equipment in certain installations
because of its relatively low cost, particularly in smaller airports and in less
developed countries.
    
 
                                       24
<PAGE>   26
 
   
     The development and deployment of advanced explosives detection technology
is being driven by recent government initiatives in the United States and
elsewhere in the world. For example, in response to the recommendations of the
White House Commission on Aviation Safety and Security (the "Gore Commission"),
in October 1996, the U.S. Congress appropriated $144 million for the procurement
of advanced explosives detection technology which the FAA is using to deploy
such technology in a limited number of the 400 busiest U.S. airports. In
addition, the BAA has installed enhanced detection technologies, including trace
detectors, in certain airports in Britain. Also, since the enactment of the
Aviation Security Act of 1990, the FAA has funded over $150 million for research
and development of advanced explosives detection technologies.
    
 
   
     Trace detection technology has a broad range of other explosives detection
uses, including other transport security, facilities protection, forensics,
military and law enforcement. For instance, trace detection equipment has been
deployed by British Rail for use on trains traveling through the Eurotunnel.
Government agencies, military forces and private businesses have deployed trace
detection equipment at facilities, such as the World Trade Center, embassies and
public utilities, such as nuclear power plants, that are perceived as potential
targets of terrorist attacks. Law enforcement agencies, such as the FBI and the
New York City Police Department, and military forces also use trace detection
technology for forensic purposes. For example, the IONSCAN(R) was recently used
in connection with the investigations of the crash of TWA Flight 800 and the
1995 Oklahoma City bombing.
    
 
     Drug Interdiction
 
   
     As a result of increased drug usage, a heightened public awareness of
drug-related criminal activity generally and the use of more sophisticated
techniques by drug traffickers, government agencies have increased their
spending on drug interdiction efforts. For example, in fiscal year 1996, the
U.S. government spent $1.4 billion on drug interdiction efforts. The use of
conventional x-ray scanning, random searches and canines has had limited success
in suppressing illegal drug trafficking. Accordingly, customs and law
enforcement agencies have increasingly turned to advanced detection technology
to assist in their drug detection and interdiction efforts. For example, the
U.S. Coast Guard has deployed trace detection equipment onboard its ships to
search vessels at sea for illegal drugs. Similarly, prisons in the U.S. and
elsewhere are employing trace detection equipment to reduce drug use.
    
 
THE BARRINGER ADVANTAGE
 
     The Company believes that its implementation of IMS technology gives the
IONSCAN(R) a distinct competitive advantage over other detection techniques,
including bulk imaging and other trace detection technologies. The IONSCAN(R)
can detect and identify targeted compounds in amounts smaller than one-billionth
of a gram. Existing bulk imaging technologies, in contrast, search for anomalies
that might indicate the presence of explosive materials but are not presently
capable of identifying specific compounds or detecting the presence of
explosives with the same sensitivity as the IONSCAN(R). In addition, because
bulk imaging technologies attempt to identify anomalies present in an object,
they reject a significantly higher number of objects that do not contain
explosives than the IONSCAN(R).
 
     The Company believes that the portability and low cost of the IONSCAN(R)
make the IONSCAN(R) particularly attractive to customers seeking a
cost-effective solution to their need for advanced detection technology. The
portability of the IONSCAN(R) allows customers to deploy the equipment where
needed. The low cost of the IONSCAN(R) relative to other existing detection
technologies allows customers in smaller installations and in less developed
countries to obtain advanced detection technology without having to incur the
significant capital expenses currently necessary to deploy bulk imaging
technologies.
 
                                       25
<PAGE>   27
 
     The Company believes that the IMS technology used in the IONSCAN(R) also
makes the IONSCAN(R) more versatile and easier to use than other detection
technologies. For example, an IONSCAN(R) can be readily used in either an
explosives detection or drug interdiction application without modification.
Currently, trace detectors utilizing other detection technologies, such as gas
chromatography, can only perform one such application.
 
     In addition the IONSCAN(R) has demonstrated its reliability in field use.
For example, based on sampling data obtained from the FAA as of July 15, 1997,
the IONSCAN(R)s deployed by the FAA to date have experienced a mean time between
failures in excess of 6,000 hours. The Company believes that this level of
reliability has not been duplicated by its competitors to date.
 
   
     The Company believes that the advantages of the IONSCAN(R) have been
recognized by the Company's customers, as demonstrated by the sale of over 500
IONSCAN(R)s as of June 30, 1997.
    
 
   
GROWTH STRATEGY
    
 
     The Company's objective is to maintain its position as the world's leading
provider of trace detection systems in its core markets and to become a leading
supplier of other advanced technology security solutions. The Company's strategy
for achieving this objective includes the following:
 
   
     Further Penetrate Existing Markets.  The Company sells its IONSCAN(R)
product in a variety of markets, including aviation security, other transport
security, facilities protection, forensics, military, corrections, customs and
law enforcement. The Company intends to extend its leadership in its existing
markets through continuous improvements to its IMS technology. In addition, the
Company intends to adapt its core IMS technology to expand its use in existing
markets. For example, the Company has received funding from the FAA for the
development of a document scanner and a token scanner for the purpose of
passenger screening at airports and an automated luggage screening system for
the purpose of screening checked luggage. See "--Product Development."
    
 
   
     Leverage IMS Technology for New Applications.  The Company believes that
the requirement for high-precision detection capability creates opportunities
for the Company's technology in applications other than explosives detection and
drug interdiction. Accordingly, the Company intends to develop products for new
applications such as quality monitoring, process control, and food and
perishable goods inspection. The Company believes that its IMS technology can
also be used to detect the presence of chemical and biological warfare agents.
    
 
     Pursue Strategic Relationships and Acquisitions.  An important element of
the Company's growth strategy is to extend its existing technology and market
expertise to attain leadership in other security markets through strategic
relationships and acquisitions. As these markets evolve and customers in both
commercial and government segments become more sophisticated, the Company
believes the ability to offer a broader scope of detection capability for use in
various current and emerging applications will become increasingly important.
Moreover, the Company believes that numerous security technologies exist that
are complementary to its own capabilities and for which the Company can provide
enhanced access to distribution, management, manufacturing and financial
resources.
 
   
     Expand Sales and Marketing Capabilities.  The Company intends to continue
to expand its sales and marketing capabilities both domestically and
internationally to capitalize on opportunities in its existing markets for new
installations as well as on opportunities in new markets. The Company intends to
hire additional sales and customer service personnel in Europe, certain
republics of the former Soviet Union, and the Middle East and, by the end of
1997, to open an office in Malaysia. Expanding its international sales and
marketing presence will provide the Company with better access to growing
foreign markets and to its existing international customer base.
    
 
IONSCAN(R) TECHNOLOGY
 
     The IONSCAN(R) is a portable, desktop system that utilizes a proprietary
implementation of IMS technology to analyze samples for the presence of targeted
chemical compounds in amounts smaller
 
                                       26
<PAGE>   28
 
than one-billionth of a gram. An operator collects samples, either by utilizing
a hand-held suction device that contains a special filter cartridge that
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
that 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 that 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 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 troubleshoot 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
U.S. Coast Guard vessel on patrol needs the capability to test a suspect vessel
for a particular type of illegal drug, the required information can be
downloaded to its unit. In addition, the Barringer Link allows the Company or
the customer to run certain diagnostic programs to determine problems that may
have occurred within a particular unit and to correct certain software problems.

SALES AND MARKETING
 
   
     The Company sells its products through a direct sales organization
comprised of 18 sales people located at its headquarters in New Jersey and at
offices in Toronto, London and Paris. The Company also intends to open an office
in Malaysia by the end of 1997. In addition, the Company utilizes a network of
49 independent sales and service representatives located in 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.
    
 
   
     Selling prices for the IONSCAN(R) average 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 provided extended warranties. To date, the Company's warranty claims
experience has not been significant. See "Risk Factors--Warranty Claims."
    
 
   
     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), management
anticipates that revenues from those activities will become increasingly less
important to the Company's overall results of operations.
    
 
     During the first six months of 1997, each of the Company's three largest
customers accounted for more than 10.0% of the consolidated revenues of the
Company. During 1996, one customer accounted for more than 10.0% of the
consolidated revenues of the Company. During 1995, no customer accounted for
more than 10.0% of the consolidated revenues of the Company. See "Risk
Factors--Dependence on Large Orders; Customer Concentrations."
 
BACKLOG
 
   
     The Company measures its backlog of instrument revenues as orders for which
contracts or purchase orders have been signed, but that have not yet been
shipped and for which revenues have not yet been recognized. The Company
includes in its backlog only those customer orders that are scheduled for
delivery within the next 18 months. The Company typically ships its products
within three months of receiving an order. For competitive purposes, the Company
follows the practice of manufacturing to a sales forecast. As a result, the
Company has not historically had a material backlog of orders for its
instruments and, in the ordinary course of business, intends to have sufficient
inventory of IONSCAN(R)s on hand to allow shipment upon receipt of an order.
However, as a result of large orders received from the FAA and the U.S. Coast
Guard in the second quarter of 1997, the Company had a $2.6 million backlog of
orders for its IONSCAN(R)s at June 30, 1997. There can be no assurance that the
Company will have a material backlog of orders in any future period.
    
 
     Substantially all of the Company's backlog at June 30, 1997 is expected to
be shipped during the current fiscal year. Any failure by the Company to meet an
agreed-upon schedule could lead to the cancellation of the related order. All
orders are subject to cancellation or delay by the customer and, accordingly,
there can be no assurance that such backlog will eventually result in revenues.
 
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 Murray
    
 
                                       30
<PAGE>   32
 
   
Hill, New Jersey. 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.
    
 
   
     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. See
"Risk Factors--Dependence on Limited Number of Suppliers."
    
 
COMPETITION
 
     The Company competes with other entities, including Thermedics Detection
Inc. ("Thermedics"), InVision Technologies, Inc. and Vivid Technologies, Inc., 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 government expenditures with equipment
manufacturers utilizing other types of detection technologies, including bulk
imaging technologies, such as enhanced x-ray and CATSCAN, as well as with
manufacturers of other IMS equipment and manufacturers using other trace
particle detection technologies, such as gas chromatography and
chemiluminescence. Because trace particle detection equipment is used in certain
instances to verify detection results obtained by bulk imaging systems, the
IONSCAN(R) and other trace particle detection products are often used in
conjunction with bulk imaging technologies. As a result of recent government
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 and Procurement Policies" and "--Competition."
    
 
     In the trace particle detection market, the Company's main competitor is
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 use 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 U.S. and most foreign countries, the aviation
industry is highly regulated and authorities, such as the FAA in the U.S., have
the ability to recommend or mandate use of enhanced explosives detection
equipment.

     The FAA is currently developing a certification protocol for trace particle
detection equipment. 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. See "Risk Factors--Dependence on and Effects of Government Regulation
and Procurement Policies."
    
 
PRODUCT DEVELOPMENT
 
   
     The Company spent $651,000, $1.1 million and $1.4 million, respectively, on
research and development activities for the six months ended June 30, 1997 and
the years ended December 31, 1996 and 1995, respectively, of which $313,000,
$858,000 and $1.1 million, respectively, were funded under various research and
development grants and contracts. Substantially all of the Company's research
and development activities have related to the development and enhancement of
the Company's IONSCAN(R) technology and the development of new IONSCAN(R)
products.
    
 
     The Company received a development grant from the FAA in October 1996 to
develop a document scanner that would scan boarding passes or other passenger
documents for the presence of explosives prior to boarding. The Company
delivered a prototype of the document scanner to the FAA in December 1996.
 
     As part of the October 1996 grant, the FAA also funded the development of a
prototype token scanner system. The token scanner would sample tokens handled by
passengers for the presence of explosives prior to boarding. The Company
delivered a prototype of the token scanner to the FAA in the second quarter of
1997.
 
   
     The Company received a design grant from the FAA in March 1997 for the
design of an automated luggage system that would scan checked baggage for the
presence of drugs or explosives. The grant does not require the production of a
prototype and no such prototype exists or is being built. However, under the
contract, the Company is required to deliver detailed design drawings to the FAA
in February 1998.
    
 
   
     In addition to these government funded activities, the Company also engages
in internal product development activities. For example, the Company is
currently attempting to develop a hand-held version of the IONSCAN(R).
    
 
     There can be no assurance that the Company will successfully complete the
development of the products described above or that any such products would, if
successfully developed, achieve market acceptance or a significant level of
sales. See "Risk Factors--Dependence on New Product Development; Technological
Advancement."
 
PATENTS, TRADEMARKS AND PROPRIETARY RIGHTS
 
     Certain of the technology used in the IONSCAN(R) is licensed by the Company
from the Canadian government as described below. While the Company holds patents
relating to certain components, systems and techniques used in the IONSCAN(R)
and while certain other elements of the IONSCAN(R) are protected by other
intellectual property rights, the Company has no comprehensive patent or similar
exclusive intellectual property right covering the IONSCAN(R) in its entirety.
In addition, the basic technology used in the IONSCAN(R) is not proprietary and
is available in the public domain. Accordingly, present and potential
competitors could use such basic technology to duplicate the performance of the
IONSCAN(R). See "Risk Factors--Limited Proprietary Technology."
 
     The 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 a worldwide
 
                                       32
<PAGE>   34
 
license to use certain unpatented technology developed from such work and pays
Revenue Canada a royalty equal to 1.0% of certain IONSCAN(R) sales. The initial
term of this license agreement expires on March 31, 1999. However, the Company
has entered into an agreement with Revenue Canada, pursuant to which the Company
has obtained the right to renew such licensing arrangement on a year-by-year
basis for up to ten additional years. 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.

Convertible Preferred Stock and Class B Convertible Preferred Stock voting as a
single class. There are no family relationships among any of the directors or
executive officers.
 
   
     Outside directors are entitled to an annual retainer of $2,500 per quarter

3,000 shares of Common Stock each year on the earlier of (i) the date of the
Company's annual meeting of stockholders, or (ii) June 1. Options granted to

    December 31, 1996.
 
   
     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.
    
 
STOCK OPTION PLANS
 
    1990 Option Plan
 
     The Company maintained an option plan (the "1990 Option Plan") pursuant to
which the Company was authorized to grant options covering a total of 100,000
shares of Common Stock. As of December 31, 1996, options covering a total of
23,750 shares of Common Stock were outstanding thereunder and no further options
could be granted thereunder. All of such options expired in January 1997.
 
    1997 Stock Compensation Program
 
     In May 1997, the Company adopted the Stock Compensation Program in order to
promote the interests of the Company, its direct and indirect present and future
subsidiaries and its stockholders by providing eligible persons with the
opportunity to acquire an ownership interest, or to increase their ownership
interest, in the Company as an incentive to remain in the service of the
Company. The Stock Compensation Program authorizes the granting of incentive
stock options, non-qualified stock options, stock appreciation rights,
performance shares and stock bonus awards to employees and consultants of the
Company and its subsidiaries, including those employees serving as officers or
directors of the Company (the "Employee Plans"). The Stock Compensation Program
also authorizes automatic option grants to directors who are not otherwise
employed by the Company (the "Independent Director Plan"). In connection with
the Stock Compensation Program, 600,000 shares of Common Stock are reserved for
issuance, of which up to 500,000 shares may be issued under the Employee Plans
and up to 100,000 shares may be issued under the Independent Director Plan. The
Stock Compensation Program is administered by the Executive Compensation
Committee of the Board of Directors.
 
     Options and awards granted under the Stock Compensation Program may have an
exercise or payment price as established by the Executive Compensation
Committee; provided that the exercise price of incentive stock options granted
under the Employee Plans may not be less than the fair market
 
                                       37
<PAGE>   39
 
value of the underlying shares on the date of grant. Options granted under the
Independent Director Plan must have an exercise price equal to the fair market
value of the underlying shares on the date of grant.
 
     Unless otherwise provided at the date of grant, no option or award may vest
within one year of the date of grant and no option or award may be exercised
more than 10 years from the date of grant. Options granted under the Independent
Director Plan vest one year following the date of grant and expire if not
exercised on or before the fifth anniversary thereof. Unless otherwise specified
by the Executive Compensation Committee, options and awards (other than pursuant
to the Independent Director Plan) vest in four equal installments on the first,
second, third and fourth anniversaries of the date of grant. Vesting of any
option or award granted under the Stock Compensation Program may be accelerated
in certain circumstances, including upon the occurrence of a "Change in Control
Event" (as defined in the Stock Compensation Program).
 
   
     Options and awards granted under the Stock Compensation Program are
nontransferable, except by will or by the laws of descent and distribution.
However, the Executive Compensation Committee may permit the recipient of a
non-incentive stock option granted under the Employee Plans and options granted
under the Independent Director Plan to transfer the option to a family member or
a trust created for the benefit of family members. During the lifetime of a
participant, an option may be exercised only by the participant or a permitted
transferee. In the event that a participant's employment or service terminates
as a result of death, all vested awards will be paid to the participant's estate
by the Company and the participant's estate or any permitted transferee will
have the right to exercise vested options for a period ending on the earlier of
the expiration dates of such options or one year from the date of death. If the
participant's employment or service terminates as a result of retirement or a
"disability" (as set forth in the Stock Compensation Program), all vested awards
will be paid to the participant by the Company and the participant or any
permitted transferee will have the right to exercise vested options for a period
ending on the earlier of the expiration dates of such options or one year from
the date of termination. If the participant's employment or service terminates
for cause, all options and awards will automatically expire upon termination. If
the participant's employment or service terminates other than as a result of
death, disability, retirement or termination for cause, the participant will
have the right to collect all vested awards immediately and the participant or
any permitted transferee will have the right to exercise vested options for a
period ending on the earlier of the expiration dates of such options or awards
or 30 days from the date of termination, subject to extension at the discretion
of the Administrator, or three months from the date of termination in the case
of options granted pursuant to the Independent Director Plan. In all cases, any
unvested options or awards will terminate as of the date of termination of
employment or service.
    
 
     The Stock Compensation Program will terminate on February 28, 2007, unless
earlier terminated by the Board of Directors. No options or awards may be
granted under the Stock Compensation Program after its termination; however,
termination of the Stock Compensation Program will not affect the status of any
option or award outstanding on the date of termination.
 
   
     Incentive stock options exercisable for an aggregate of 135,500 shares of
Common Stock have been granted to date under the Employee Plans. These options
expire 10 years after the date of grant and have an exercise price, subject to
adjustment, of $9.375 per share. Such options are exercisable annually in 25%
increments beginning with the first anniversary of the date of grant. In
addition, pursuant to the terms of the Independent Director Plan, options
exercisable for an aggregate of 12,000 shares were granted to the Company's
independent directors. These options become exercisable one year from the date
of grant, expire five years from the date of grant and have an exercise price,
subject to adjustment, of $13.875 per share.
    
 
    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
 
                                       38
<PAGE>   40
 
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 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.
 
     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 Exercise
Program, representing interest otherwise payable on such notes.
 
EMPLOYMENT AGREEMENTS AND COMPENSATION ARRANGEMENTS
 
   
     The Company has entered into an Employment Agreement with Mr. Binder, the
President and Chief Executive Officer of the Company (the "Employment
Agreement"), pursuant to which Mr. Binder receives $171,000 annually as
compensation, subject to increases equal to percentage increases in the Consumer
Price Index as well as increases authorized by the 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 of grant.
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
Transactions."
    
 
     The Company has entered into employment agreements with Messrs. Wood and
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 Mr. 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.

INDEMNIFICATION OF THE DIRECTORS AND OFFICERS
 
     The Certificate of Incorporation and 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. 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 Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable.

                              CERTAIN TRANSACTIONS
 
GENERAL
 
   
     In May 1995, the Company sold to SSF III, which is controlled by Mr. Marxe
and of which Mr. Binder is an independent general partner with approximately a
0.01% interest in such partnership, and to the Special Situations Cayman Fund,
LP, 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, in June 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.
    
 
     For a description of certain transactions between Labco and the Company,
see "--Sale of Subsidiary" and "Management--Compensation Committee Interlocks
and Insider Participation."
 
     In July 1996, the Company sold to SSF $450,000 in principal amount of the
Company's 6% Subordinated Convertible Debentures due 1997 (the "Debentures").
The Debentures bore interest at the rate of 6.0% per annum, were convertible
into shares of Common Stock at a conversion rate of $2.75 and, pursuant to their
terms, matured 30 days after the consummation of the Company's November 1996
public offering, unless converted prior thereto. Certain officers and directors
of the Company purchased an additional $100,000 in aggregate principal amount of
the Debentures. All of the Debentures were converted into shares of Common Stock
in December 1996.
 
     Mr. Abernathy is currently the Executive Director of Patton Boggs, LLP, a
Washington, D.C. law firm. During 1996, the Company retained Patton Boggs, LLP
to represent the Company in various matters and has retained such firm in 1997.
 
SALE OF SUBSIDIARY
 
   
     Prior to December 1995, the Company controlled 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. 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"), subject to the return of the Retained Shares to the Company upon Labco
meeting 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. 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 with respect to, and to terminate the other 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 agreed to
 
                                       41
<PAGE>   43
 
sell its Labco shares as provided above upon receipt of an offer to acquire such
shares at a price per share at least equal to the Target Price. The restrictions
described above also applied to any shares of Labco common stock issuable to the
Company upon the exercise of certain warrants held by the Company. Labco
registered the Company's Labco shares for resale pursuant to the Securities Act
to facilitate such sales.
 
     In the Termination Agreement, the Company also 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, Messrs. Binder and Harte agreed to resign their
positions with Labco.
 
     As of December 31, 1996, the Company had sold its entire interest in Labco
and, pursuant to the terms of the Termination Agreement, Messrs. Binder and
Harte had resigned their respective positions with Labco.

                          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 20,000,000 shares of
Common Stock, par value $0.01 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 August 1, 1997, the Company had outstanding
5,475,179 shares of Common Stock, no shares of Convertible Preferred Stock,
45,146 shares of Class A Convertible Preferred Stock and 22,500 shares of Class
B Convertible Preferred Stock. The Company currently intends to redeem the
outstanding shares of Class A Convertible Preferred Stock and Class B
Convertible Preferred Stock as soon as permitted under the terms thereof. Upon
completion of this Offering, the Company will have outstanding 7,475,179 shares
of Common Stock (7,693,179 shares if the Underwriters' over-allotment option is
exercised in full). In addition, the Company will have 1,502,899 shares of
Common Stock reserved for issuance pursuant to options, warrants and convertible
securities outstanding as of August 1, 1997. See "Shares Eligible For Future
Sale." As of August 1, 1997, 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 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 by the Company pursuant to the Offering
will be, upon payment therefor, fully paid and non-assessable.
 
PREFERRED STOCK
 
     The Preferred Stock may be issued from time to time in one or more classes
or series, and the 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 holders of Common Stock. For example,
Preferred Stock issued by the Company may rank senior to the Common Stock as to
dividend rights,
 
                                       45
<PAGE>   47
 
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 Board of Directors has designated two series of Preferred Stock, the
Class A Convertible Preferred Stock and the Class B Convertible Preferred Stock.
As indicated above, the Company currently intends to redeem the outstanding
shares of Class A Convertible Preferred Stock and Class B Convertible Preferred
Stock as soon as permitted under the terms thereof. Based on the recent trading
history for the Common Stock, the Company anticipates that it will be permitted
to redeem the outstanding shares of Class A Convertible Preferred Stock and
Class B Convertible Preferred Stock on or about September 18, 1997.
 
     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 Board of Directors,
cumulative dividends at an annual rate of $0.16 per share, payable semi-annually
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 0.361745 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 Board of Directors,
cumulative dividends at an annual rate of $0.16 per share, payable semi-annually
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 0.355839 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, 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.
    
 
                                       46
<PAGE>   48
 
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 Board of
Directors, cumulative dividends at an annual rate of $.10 per share, payable
semi-annually in Common 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
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, 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 Certificate of Incorporation contains provisions which require the
favorable vote by the holders of not less than 80.0% 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 10.0% 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.
 
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 15.0% 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 85.0% of the corporation's voting stock in the
same transaction in which it exceeds 15.0%, 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 is American Stock
Transfer & Trust Company, New York, New York.

COMMON STOCK PURCHASE WARRANTS
 
     In connection with its November 1996 public offering, the Company issued an
aggregate of 1,437,500 Common Stock Purchase Warrants (the "Warrants"). 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 certain circumstances. The Warrants are
subject to redemption by the Company, at $0.25 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. The Company may, in
its sole discretion, lower the exercise price of the Warrants for a period of
not less than 30 days on not less than 30 days' prior written notice. 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.
 
   
     In connection with the November 1996 public offering, the Company sold to
Janney, Montgomery Scott, Inc. Underwriter's Warrants (the "Underwriter's
Warrants") 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
$0.06 per Warrant. The Underwriter's Warrants are exercisable with respect to
the Common Stock for a period of four years commencing November 12, 1997 and
with respect to the Warrants for a period of two years commencing November 12,
1997.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     Upon completion of this Offering, based on shares outstanding as of August
1, 1997, the Company will have outstanding approximately 7,475,179 shares of
Common Stock assuming no exercise or conversion of options, warrants and
convertible securities after August 1, 1997. All of the outstanding shares,
including the 2,000,000 shares offered hereby (2,218,000 shares if the
Underwriters' over-allotment option is exercised in full), will be freely
tradable without restriction or further registration under the Securities Act,
unless purchased by "affiliates" of the Company as that term is defined in Rule
144 under the Securities Act. An additional 1,502,899 shares of Common Stock are
issuable upon the conversion or exercise of stock options, warrants and
convertible securities outstanding as of August 1, 1997, 1,346,649 of which have
been registered for resale by the holders thereof and are, therefore, freely
tradable and the balance of which are subject to registration rights pursuant to
which the holders thereof can cause the Company to effect the registration of
such shares for resale.
    
 
   
     The holders of an aggregate of 770,297 shares of Common Stock (including
555,250 shares issuable upon the exercise or conversion of outstanding options,
warrants and convertible securities), have agreed with the Underwriters not to
offer or sell, directly or indirectly, or otherwise reduce their risk in, any
securities of the Company, other than pursuant to the exercise of the
Underwriters' over-allotment option, for a period of 90 days after the date of
this Prospectus, subject to certain exceptions, without the prior written
consent of Robertson, Stephens & Company. Following the lock-up period, all of
the shares subject to the lock-up agreements will be available for immediate
sale.
    
 
     Sales of substantial amounts of such shares in the public market, or the
perception that such sales might occur, could adversely affect the market price
of the Common Stock and could impair the Company's future ability to raise
capital through an offering of its equity securities. See "Risk Factors--Shares
Eligible for Future Sale."

</TABLE>
 
     The Company has been advised by the Representatives that the Underwriters
propose to offer the shares of Common Stock to the public at the public offering
price set forth on the cover page of this Prospectus and to certain dealers at
such price less a concession of not more than $          per share, of which
$          may be reallowed to other dealers. After the public offering, the
public offering price, concession and reallowance to dealers may be reduced by
the Representatives. No such reduction shall change the amount of proceeds to be
received by the Company as set forth on the cover page of this Prospectus.
 
     The Company and certain Selling Stockholders have granted to the
Underwriters an option, exercisable during the 30-day period after the date of
this Prospectus, to purchase up to 300,000 additional shares of Common Stock at
the same price per share as the Company receives for the 2,000,000 shares that
the Underwriters have agreed to purchase. To the extent that the Underwriters
exercise such option, each of the Underwriters will have a firm commitment to
purchase approximately the same percentage of such additional shares that the
number of shares of Common Stock to be purchased by it shown in the above table
represents as a percentage of the 2,000,000 shares offered hereby. If purchased,
such additional shares will be sold by the Underwriters on the same terms as
those on which the 2,000,000 shares are being sold.
 
     The Underwriting Agreement contains covenants of indemnity between the
Underwriters, the Company and the Selling Stockholders against certain civil
liabilities, including liabilities under the Securities Act.
 
   
     The executive officers and directors of the Company, who hold an aggregate
of 770,297 shares of Common Stock (including 555,250 shares issuable upon the
exercise or conversion of outstanding options, warrants and convertible
securities), have agreed with the Underwriters that, for a period of 90 days
from the date of this Prospectus (the "Lock-Up Period"), other than pursuant to
the exercise of the Underwriters' over-allotment option, they will not offer to
sell, contract to sell, or otherwise sell, dispose of, loan, pledge or grant any
rights with respect to any shares of Common Stock, any options or warrants to
purchase any shares of Common Stock, or any securities convertible into or
exchangeable for shares of Common Stock, now owned or hereafter acquired
directly by such holders or with respect to which such holders have or hereafter
acquire the power of disposition (subject to certain exceptions) without the
prior written consent of Robertson, Stephens & Company LLC, which may, in its
sole discretion and at any time or from time to time, without notice, release
all or any portion of the shares subject to the lock-up agreements. In addition,
the Company has agreed that during the Lock-Up Period, it will not, without the
prior written consent of Robertson, Stephens & Company LLC, issue, sell,
contract to sell or otherwise dispose of any shares of Common Stock, any options
or warrants to purchase any shares of Common Stock or any securities convertible
into, exercisable for or exchangeable for shares of Common Stock other than the
issuance of Common Stock upon the exercise of outstanding options and warrants
and the Company's issuance of options under existing employee stock option
plans.

     The offering price of the Common Stock was determined by negotiations among
the Company and the Representatives of the Underwriters, based in part upon the
market price for the Common Stock as reported on the Nasdaq National Market.
 
     In connection with this Offering, certain Underwriters and selling group
members (if any) who are qualified market makers on The Nasdaq Stock Market may
engage in passive market making transactions in the Common Stock on The Nasdaq
Stock Market in accordance with Rule 103 of Regulation M under the Exchange Act
during the business day prior to the pricing of this Offering before the
commencement of offers or sales of the Common Stock. Passive market makers must
comply with applicable volume and price limitations and must be identified as
such. In general, a passive market maker must display its bid at a price not in
excess of the highest independent bid for such security; if all independent bids
are lowered below the passive market maker's bid, however, such bid must then be
lowered when certain purchase limits are exceeded.
 
     Certain persons participating in this Offering may overallot or effect
transactions which stabilize, maintain or otherwise affect the market price of
the Common Stock at levels above those which might otherwise prevail in the open
market, including by entering stabilizing bids or effecting syndicate covering
transactions. A stabilizing bid means the placing of any bid or effecting of any
purchase, for the purpose of pegging, fixing or maintaining the price of the
Common Stock. A syndicate covering transaction means the placing of any bid on
behalf of the underwriting syndicate or the effecting of any purchase to reduce
a short position created in connection with this Offering. Such transactions may
be effected on The Nasdaq Stock Market, in the over-the-counter market or
otherwise. Such stabilizing, if commenced, may be discontinued at any time.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
 
Barringer Technologies Inc.
Murray Hill, New Jersey
 
     We have audited the accompanying consolidated balance sheets of Barringer
Technologies Inc. as of December 31, 1995 and 1996 and the related consolidated
statements of operations, stockholders' equity, and cash flows for each of the
three years in the period ended December 31, 1996. These financial statements
are the responsibility of the Company's management. Our responsibility is to
express an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the financial
statements. 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 1996, and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1996 in conformity with generally accepted accounting principles.
 
     Also, in our opinion, the schedule presents fairly, in all material
respects, the information set forth therein.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
    (INFORMATION WITH RESPECT TO JUNE 30, 1997 AND FOR THE SIX MONTHS ENDED
                      JUNE 30, 1996 AND 1997 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 statement of operation 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
 
     Net 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 (loss) 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 recognize revenue on the percentage of completion method
similar to its recognition method in the research and development business.

                  BARRINGER TECHNOLOGIES INC. AND SUBSIDIARIES
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
     For the years ended December 31, 1994, 1995 and 1996, the Company had
recognized revenues of $17,000, $264,000 and $49,000 respectively, on jobs in
process and had incurred related costs of $10,000, $183,000 and $25,000
respectively, of which $5,000, $210,000 and $0 respectively, were billed to
customers. For the six months ended June 30, 1997, the Company did not have any
significant contracts in progress.
 
  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 to
primarily governmental agencies. Marketable securities consists primarily of
investments in U.S. government and agency obligations and commercial paper.
 
  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. If and 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, ("SFAS
121") "Accounting for the Impairment of Long-Lived Assets and Long-Lived Assets
to be Disposed of", which the Company adopted effective for the year ended
December 31, 1996. No write-downs have been necessary through June 30, 1997 as a
result of SFAS 121.
 
  Stock-Based Compensation
 
     The Company has adopted the disclosure only provisions of SFAS 123,
"Accounting for Stock-Based Compensation", but applies Accounting Principle
Board Opinion No. 25 in accounting and measuring compensation expense related to
stock option plans. There was no compensation expense related to the issuance of
stock options for the years ended December 31, 1994, 1995 and 1996 and for the
six months ended June 30, 1996 and 1997. (see note 7 for pro-forma disclosure
required by SFAS 123).
 
  Fair Value of Financial Instruments
 
     The carrying amounts reported in the consolidated balance sheets for cash
and cash equivalents, marketable securities, accounts receivable, accounts
payable, accrued liabilities and notes payable approximate fair value because of
the immediate or short-term maturity of these financial instruments. The Company
has the ability and intent to hold all marketable securities through their
respective maturity dates.
 
  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 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 accounts receivable, inventories,
equipment and deferred income taxes.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
  Unaudited Information
 
     The consolidated balance sheet of the Company as of June 30, 1997, the
consolidated statements of operations and cash flows for the six months ended
June 30, 1996 and 1997, the consolidated statement of stockholders' equity for
the six months ended June 30, 1997 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 any other interim
or annual period.
 
2.  INVESTMENT IN UNCONSOLIDATED SUBSIDIARY
 
     During the first quarter of 1995, the Company started to actively seek a
purchaser for its then 47% interest in Barringer Laboratories, Inc ("Labco").
Accordingly, the financial statements had 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 $300,000 in cash, cancellation of all amounts owed by the Company
to Labco pursuant to certain intercompany agreements (aggregating $452,000) and
cancellation of $57,000 in accounts receivable due to Labco. After giving effect
to the sale of the Labco shares, the Company continued to own 432,475 shares of
Labco stock representing a 26% ownership interest.
 
     In October 1996, the Company and Labco entered into a Termination Agreement
(the "Termination Agreement") pursuant to which, among other things, the Company
agreed that, for a period of three months from the date of the Termination
Agreement, it would sell its remaining shares in Labco at a price of at least
$1.6875 per share. During 1996, the Company sold all of its remaining shares and
warrants in Labco and recognized a gain on such sales of $123,000. In addition
to the gain on the sale of its Labco investment, the Company recorded $117,000
of income representing its proportionate share of Labco's net income for 1996.
 
3.  INVENTORIES
 
     At December 31, 1995 and 1996 and June 30, 1997, the Company had parts,
subassemblies and work in process of $1,010,000, $1,483,000, and $2,953,000 and
finished goods of $611,000, $787,000, and $471,000, respectively.

5.  BANK INDEBTEDNESS AND OTHER NOTES PAYABLE
 
     The Company's Canadian subsidiary, Barringer Research Ltd. ("BRL"), had a
financing arrangement with the Ontario Development Corporation ("ODC") for a
$730,000 export line of credit. The rate of interest was adjusted quarterly and
was 10% at December 31, 1996 and outstanding borrowings totaled $150,000. The
ODC has informed the Company that this facility will no longer be available due
to the phasing out of the ODC by the Canadian government. In January 1997, the
Company paid all amounts owed to the ODC and the facility was terminated.
 
     BRL's line of credit arrangement with the Toronto-Dominion Bank ("Bank")
was terminated by BRL in December 1996 upon the payment of all amounts due to
the Bank. During December 1996, the Company placed in an interest bearing
account $280,000 in order to secure a performance bond that was previously
issued by the Bank. At December 31, 1996, this deposit was restricted. On
February 12, 1997, the bond was canceled and the deposit released.
 
6.  CURRENT PORTION OF LONG-TERM DEBT AND OTHER NON-CURRENT LIABILITIES
 
     (a) Current portion of long-term debt at December 31, 1995, consisted of
amounts due on the 12 1/2% Convertible Subordinated Debentures which were repaid
on July 15, 1996 with a portion of the net proceeds from the sale of $1,000,000
of 6% Convertible Subordinated Debentures due 1997 (see note 7).
 
     (b) Other non-current liabilities represent rents payable on the Company's
Canadian facility.
 
7.  STOCKHOLDERS' EQUITY
 
  Public Offering
 
     On November 12, 1996, the Company completed the sale of 1,250,000 shares
("Shares") of common stock and 1,250,000 Common Stock Purchase Warrants
("Warrants") in a public underwriting. On December 12, 1996, the underwriters
exercised their over-allotment option and acquired an additional 187,500 Shares
and 187,500 Warrants. The aggregate net proceeds to the Company, after all
expenses of the offering, was approximately $10,401,000.
 
  Private Offerings
 
     On May 9, 1995, the Company completed the private placement of its
securities to two institutional investors. The private placement consisted of
125 units priced at $6,000 each for an aggregate sales price of $750,000. Each
unit ("Unit") consisted of 2,500 shares of the Company's common stock and a
five-year warrant to purchase 2,500 shares of the Company's common stock at
$1.96 per share. In addition, in order to induce the institutional investors to
enter into this transaction, an additional three-year warrant to acquire 37,500
shares of the Company's common stock at $1.96 per share was issued.
 
     On June 30, 1995, the Company completed an additional private placement in
which it sold an additional 28 Units, including 22 Units to 17 members of senior
management and the Company's Board of Directors, for proceeds aggregating
$168,000. This private placement did not include the additional three-year
warrant.
 
     On July 10, 1996, the Company completed the sale of $1,000,000 of its 6%
Convertible Subordinated Debentures, ("Debentures") due 1997, in a private
transaction to private investors including members of management. These
debentures are convertible into shares of the Company's Common Stock at the rate
of $2.75 per share and mature on the earlier of (i) 30 days after the completion
of an underwritten public offering or a private placement by the Company of its
equity 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 semi-annually. A portion
of the net proceeds of the sale of these debentures were used to repay the
12 1/2% Subordinated Convertible Debentures due 1996. All of the Debentures were
converted into 363,628 shares of common stock in December 1996, as a result of
the public offering.
 
  Due from Officers/Shareholders
 
     In connection with the exercise of options to acquire 190,000 shares of the
Company's Common Stock, two officers of the Company signed full recourse
interest bearing (no interest the first year, prime rate thereafter) unsecured
promissory demand notes aggregating $274,000 that was available to them under
the Company's stock option purchase program. Under that program the Company has
arranged for a market-maker in the Company's Common Stock, to coordinate the
orderly sale in the open market of a portion of the Common Stock to be received
by the employees upon the exercise of their options in an amount sufficient to
repay the loan and related interest. As of June 30, 1997, $203,000 was still
outstanding.
 
  Common Stock Outstanding or Reserved for Issuance
 
     The following table sets forth the number of shares of Common Stock
outstanding as of December 31, 1996 as well as the number of shares of Common
Stock that would be outstanding in the event that all of the options and
warrants are exercised and all Series of Convertible Preferred Stock and
Debentures are converted into Common Stock.

  (i) Stock Compensation Plans
 
     From time to time, the Company has granted non-qualified options to various
employees and directors. The Company applies APB Opinion 25, "Accounting for
Stock Issued to Employees", and related Interpretations in accounting for the
plans. Under APB Opinion 25, because the exercise price of the Company's stock
options issued to employees equals the market price of the underlying stock on
the date of grant, no compensation is recognized.
 
     SFAS 123, "Accounting for Stock-Based Compensation", requires the Company
to provide pro forma information regarding net income (loss) and earnings (loss)
per share as if compensation cost

for the Company's stock option plans had been determined in accordance with the
fair value based method prescribed in SFAS 123. The Company estimates the fair
value of each stock option at the grant date by using the Black-Scholes
option-price model with the following weighted average assumptions used for
grants in 1995 and 1996, respectively: no dividend yield; expected volatility of
30%; risk-free interest rates of 7.11% and expected lives of 5 years for the
options.
 
     Under the accounting provisions of SFAS 123, the Company's net income
(loss), primary earnings (loss) per share and fully diluted earnings (loss) per
share would have been reduced (increased) to the pro-forma amounts indicated
below.

     At the May 13, 1997 Annual Meeting of Stockholders, the Company's
stockholders approved the adoption of the Company's 1997 Stock Compensation
Program ("Program"). The Program authorizes the granting of incentive stock
options, non-qualified supplementary options, stock appreciation rights,
performance shares and stock bonus awards to employees and consultants of the
Company and its subsidiaries, including those employees serving as officers or
directors of the Company ("Employee Plans"). The Program also authorizes
automatic option grants to directors who are not otherwise employed by the
Company ("Independent Director Plan"). In connection with the Program, 600,000
shares of Common Stock are reserved for issuance, of which up to 500,000 shares
may be issued under the Employee Plans and up to 100,000 shares may be issued
under the Independent Director Plan. In the event that an option or award
granted under the Program expires, is terminated or forfeited or certain
performance objectives with respect thereto are not met prior to exercise or
vesting, then the number of shares of Common Stock covered thereby will again
become eligible for grant under the Program. The Company will receive no
consideration for grants of options or awards under the Program.

</TABLE>
 
     As a result of the Company's historical trend of losses, a valuation
allowance has been provided for a substantial portion of the U.S. and Canadian
deferred tax assets. At December 31, 1995, the net deferred tax asset of
$225,000 related to the Company's Canadian subsidiary, which had available tax
credits and loss carryforwards. The Canadian subsidiary has a history of
profitability, despite the consolidated losses of the Company through December
31, 1995. At December 31, 1996, the net deferred tax asset of $731,000, included
approximately $525,000 and $206,000 related to the Company's Canadian and U.S.
operations, respectively. At June 30, 1997, the net deferred tax asset of
$1,031,000, included approximately $525,000 and $506,000 related to the
Company's Canadian and U.S. operations, respectively. Based on historical
results and estimated 1997 and 1998 earnings, which include earnings from
certain contracts, as well as available tax planning strategies, management
considers realization of the unreserved deferred tax asset more likely than not.
Additional reductions to the valuation allowance will be recorded when, in the
opinion of management, the Company's ability to generate taxable income is
considered more likely than not.

10.  PENSION PLAN
 
     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 in 1993, representing the excess of the Plan's
projected benefit obligation over the accumulated benefit obligation 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

consolidated balance sheet.
 
     The Company maintains a 401(k) salary deferral plan instituted for all U.S.
employees with more than one year of service. As a money purchase plan, it does
not establish any Company liability other than a matching formula to employee
contributions. The aggregate cost of the plan for 1994, 1995, and 1996 and for
the six months ended June 30, 1996 and 1997 was $16,000, $15,700, $20,000,
$9,000 and $20,000, respectively.

                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 24.  INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     The Certificate of Incorporation, as amended (the "Certificate of
Incorporation"), and 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.
 
     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.

     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

ITEM 28.  UNDERTAKINGS
 
     The undersigned registrant hereby undertakes:
 
          (1) For the purpose of determining any liability under the Securities
     Act of 1933, as amended (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.
 
                                      II-4
<PAGE>   81
 
          (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
     indemnification, 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.

certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form SB-2 and authorizes this amendment to the
registration statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the Borough of New Providence, State of New Jersey, on

      Delivery of definitive certificates for the Firm Shares to be purchased by
the Underwriters pursuant to this Section 3 shall be made against payment of the
purchase price therefor by the several Underwriters by certified or official
bank check or checks drawn in next-day funds, payable to the order of the

the Representatives and the Company), at 7:00 A.M., San Francisco time (a) on
the third (3rd) full business day following the first day that Shares are

Francisco time, the fourth (4th) full


                                     - 15 -

business day following the day that this Agreement is executed and delivered, or
(c) at such other time and date not later than seven (7) full business days
following the first day that Shares are traded as the Representatives and the
Company may determine (or at such time and date to which payment and delivery
shall have been postponed pursuant to Section l0 hereof), such time and date of
payment and delivery being herein called the "Closing Date;" provided, however,
that if the Company has not made available to the Representatives copies of the
Prospectus within the time provided in Section 4(d) hereof, the Representatives
may, in their sole discretion, postpone the Closing Date until no later than two
(2) full business days following delivery of copies of the Prospectus to the
Representatives. The certificates for the Firm Shares to be so delivered will be
made available to you at such office or such other location including, without
limitations in New York City, as you may reasonably request for checking at
least one (1) full business day prior to the Closing Date and will be in such
names and denominations as you may request, such request to be made at least two
(2) full business days prior to the Closing Date. If the Representatives so
elect, delivery of the Firm Shares may be made by credit through full fast
transfer to the accounts at The Depository Trust Company designated by the
Representatives.

      It is understood that you, individually, and not as the Representatives of
the several Underwriters, may (but shall not be obligated to) make payment of
the purchase price on behalf of any Underwriter or Underwriters whose check or
checks shall not have been received by you prior to the Closing Date for the
Firm Shares to be purchased by such Underwriter or Underwriters. Any such
payment by you shall not relieve any such Underwriter or Underwriters of any of
its or their obligations hereunder.

      After the Registration Statement becomes effective, the several
Underwriters intend to make an initial public offering (as such term is
described in Section 11 hereof) of the Firm Shares at an initial public offering
price of $_____ per share. After the initial public offering, the several
Underwriters may, in their discretion, vary the public offering price.

cover concerning stabilization, over-allotment and passive market making by the
Underwriters, and under the caption "Underwriting" in any Preliminary Prospectus
and in the Prospectus constitutes the only information furnished by the

Prospectus or the Registration Statement, and you, on behalf of the respective
Underwriters, represent and warrant to the Company and the Selling Stockholders

material fact or omit to state a material fact required to be stated therein or

      4. Further Agreements of the Company. The Company agrees with the several
Underwriters that:

            (a) The Company will use its best efforts to cause the Registration
Statement and any amendment thereof, if not effective at the time and date that
this Agreement is executed and delivered by the parties hereto, to become

cause any abbreviated registration statement pursuant to Rule 462(b) of the
Rules and Regulations as may be required subsequent to the date the Registration
Statement is declared effective to become effective as promptly as possible; the
Company will notify you, promptly after it shall receive notice thereof, of the
time when the Registration Statement, any subsequent amendment to the
Registration Statement or any abbreviated registration statement has become
effective or any supplement to the Prospectus has been filed; if the Company
omitted information from the Registration Statement at the time it was
originally declared effective in reliance upon Rule 430A(a) of the Rules and
Regulations, the Company will provide evidence satisfactory to you that the
Prospectus contains such information and has been filed, within the time period
prescribed, with the Commission pursuant to subparagraph (l) or (4) of Rule
424(b) of the Rules and Regulations or as part of a post-effective amendment to
such Registration Statement as originally declared effective which is declared
effective by the Commission; if the Company files a term sheet pursuant to Rule
434 of the Rules and Regulations, the Company will provide evidence satisfactory
to you that the Prospectus and term sheet meeting the requirements of Rule
434(b) or (c), as applicable, of the Rules and Regulations, have been filed,
within the time period prescribed, with the Commission pursuant to subparagraph
(7) of Rule 424(b) of the Rules and Regulations; if for any reason the filing of
the final form of Prospectus is required under Rule 424(b)(3) of the Rules and
Regulations, it will provide evidence satisfactory to you that the Prospectus
contains such information and has been filed with the Commission within the time
period prescribed; it will notify you promptly of any request by the Commission
for the amending or supplementing of the Registration Statement or the
Prospectus or for additional information; promptly upon your request, it will

several Underwriters ("Underwriters' Counsel"), may be necessary or advisable in
connection with the distribution of the Shares by the Underwriters; it will
promptly prepare and file with the Commission, and promptly notify you of the
filing of, any amendments or supplements to the Registration Statement or
Prospectus which may be necessary to correct any statements or omissions, if, at
any time when a prospectus relating to the Shares is required to be delivered
under the Act, any event shall have occurred as a result of which the Prospectus
or any other prospectus relating to the Shares as then in effect would include
any untrue statement of a material fact or omit to state a material fact
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading; in case any Underwriter is required
to deliver a prospectus nine (9) months or more after the effective date of the
Registration Statement in connection with the sale of the Shares, it will
prepare promptly upon request, but at the


                                     - 17 -
<PAGE>   18

expense of such Underwriter, such amendment or amendments to the Registration
Statement and such prospectus or prospectuses as may be necessary to permit
compliance with the requirements of Section 10(a)(3) of the Act; and it will
file no amendment or supplement to the Registration Statement or Prospectus
which shall not previously have been submitted to you a reasonable time prior to
the proposed filing thereof or to which you shall reasonably object in writing,
subject, however, to compliance with the Act and the Rules and Regulations and
the provisions of this Agreement.

            (b) The Company will advise you, promptly after it shall receive
notice or obtain knowledge, of the issuance of any stop order by the Commission
suspending the effectiveness of the Registration Statement or of the initiation

efforts to prevent the issuance of any stop order or to obtain its withdrawal at
the earliest possible moment if such stop order should be issued.

            (c) The Company will use its best efforts to qualify the Shares for
offering and sale under the securities laws of such jurisdictions as you may
designate and to continue such qualifications in effect for so long as may be
required for purposes of the distribution of the Shares, except that the Company
shall not be required in connection therewith or as a condition thereof to
qualify as a foreign corporation or to execute a general consent to service of
process in any jurisdiction in which it is not otherwise required to be so
qualified or to so execute a general consent to service of process. In each
jurisdiction in which the Shares shall have been qualified as above provided,
the Company will make and file such statements and reports in each year as are
or may be required by the laws of such jurisdiction.

      5. Expenses.

            (a) The Company agrees with each Underwriter [and each Selling
Stockholder] that:

                  (i) The Company will pay and bear all costs and expenses in
connection with the preparation, printing and filing of the Registration
Statement (including financial statements, schedules and exhibits), Preliminary
Prospectuses and the Prospectus and any amendments or supplements thereto; the
printing of this Agreement, the Agreement Among Underwriters, the Selected
Dealer Agreement, the Preliminary Blue Sky Survey and any Supplemental Blue Sky
Survey, the Underwriters' Questionnaire and Power of Attorney, and any
instruments related to any of the foregoing; the issuance and delivery of the
Shares hereunder to the several Underwriters, including transfer taxes, if any,

accountants; the cost of furnishing to the several Underwriters copies of the

                                     - 20 -
<PAGE>   21

performance of [its][their] obligations hereunder. [Any additional expenses
incurred as a result of the sale of the Shares by the Selling Stockholders will
be borne collectively by the Company and the Selling Stockholders.] The
provisions of this Section 5(a)(i) are intended to relieve the Underwriters from
the payment of the expenses and costs which the Selling Stockholders and the
Company hereby agree to pay, but shall not affect any agreement which the
Selling Stockholders and the Company may make, or may have made, for the sharing
of any of such expenses and costs. Such agreements shall not impair the
obligations of the Company and the Selling Stockholders hereunder to the several
Underwriters.

                  (ii) In addition to its other obligations under Section 8(a)
hereof, the Company agrees that, as an interim measure during the pendency of
any claim, action, investigation, inquiry or other proceeding described in
Section 8(a) hereof, it will reimburse the Underwriters on a monthly basis for
all reasonable legal or other expenses incurred in connection with investigating
or defending any such claim, action, investigation, inquiry or other proceeding,
notwithstanding the absence of a judicial determination as to the propriety and
enforceability of the Company's obligation to reimburse the Underwriters for
such expenses and the possibility that such payments might later be held to have
been improper by a court of competent jurisdiction. To the extent that any such
interim reimbursement payment is so held to have been improper, the Underwriters
shall promptly return such payment to the Company together with interest,
compounded daily, determined. on the basis of the prime rate (or other
commercial lending rate for borrowers of the highest credit standing) listed
from time to time in The Wall Street Journal which represents the base rate on
corporate loans posted by a substantial majority of the nation's thirty (30)
largest banks (the "Prime Rate"). Any such interim reimbursement payments which
are not made to the Underwriters within thirty (30) days of a request for
reimbursement shall bear interest at the Prime Rate from the date of such
request.

                  (iii) In addition to their other obligations under Section
8(b) hereof, each Selling Stockholder agrees that, as an interim measure during
the pendency of any claim, action, investigation, inquiry or other proceeding
described in Section 8(b) hereof relating to such Selling Stockholder, it will
reimburse the Underwriters on a monthly basis for all reasonable legal or other
expenses incurred in connection with investigating or defending any such claim,
action, investigation, inquiry or other proceeding, notwithstanding the absence
of a judicial determination as to the propriety and enforceability of such
Selling Stockholder's obligation to reimburse the Underwriters for such expenses
and the possibility that such payments might later be held to have been improper
by a court of competent jurisdiction. To the extent that any such interim
reimbursement payment is so held to have been improper, the Underwriters shall
promptly return such payment to the Selling Stockholders, together with
interest, compounded daily, determined on the basis of the Prime Rate. Any such
interim reimbursement payments which are not made to the Underwriters within
thirty (30) days


                                     - 21 -
<PAGE>   22

of a request for reimbursement shall bear interest at the Prime Rate from the
date of such request.

            (b) In addition to their other obligations under Section 8(c)
hereof, the Underwriters severally and not jointly agree that, as an interim
measure during the pendency of any claim, action, investigation, inquiry or
other proceeding described in Section 8(c) hereof, they will reimburse the
Company and each Selling Stockholder on a monthly basis for all reasonable legal
or other expenses incurred in connection with investigating or defending any
such claim, action, investigation, inquiry or other proceeding, notwithstanding
the absence of a judicial determination as to the propriety and enforceability
of the Underwriters' obligation to reimburse the Company and each such Selling
Stockholder for such expenses and the possibility that such payments might later
be held to have been improper by- a court of competent jurisdiction. To the
extent that any such interim reimbursement payment is so held to have been
improper, the Company and each such Selling Stockholder shall promptly return
such payment to the Underwriters together with interest, compounded daily,
determined on the basis of the Prime Rate. Any such interim reimbursement
payments which are not made to the Company and each such Selling Stockholder
within thirty (30) days of a request for reimbursement shall bear interest at
the Prime Rate from the date of such request.

            (c) It is agreed that any controversy arising out of the operation
of the interim reimbursement arrangements set forth in Sections 5(a)(ii),
5(a)(iii) and 5(b) hereof, including the amounts of any requested reimbursement
payments, the method of determining such amounts and the basis on which such
amounts shall be apportioned among the reimbursing parties, shall be settled by
arbitration conducted under the provisions of the Constitution and Rules of the
Board of Governors of the New York Stock Exchange, Inc. or pursuant to the Code
of Arbitration Procedure of the NASD. Any such arbitration must be commenced by
service of a written demand for arbitration or a written notice of intention to
arbitrate, therein electing the arbitration tribunal. In the event the party
demanding arbitration does not make such designation of an arbitration tribunal
in such demand or notice, then the party responding to said demand or notice is
authorized to do so. Any such arbitration will be limited to the operation of
the interim reimbursement provisions contained in Sections 5(a)(ii), 5(a)(iii)
and 5(b) hereof and will not resolve the ultimate propriety or enforceability of
the obligation to indemnify for expenses which is created by the provisions of
Sections 8(a), 8(b) and 8(c) hereof or the obligation to contribute to expenses
which is created by the provisions of Section 8(e) hereof.

      6. Conditions of Underwriters' Obligations. The obligations of the several
Underwriters to purchase and pay for the Shares as provided herein shall be
subject to the accuracy, as of the date hereof and the Closing Date and any
later date on which Option Shares are to be purchased, as the case may be, of
the representations and warranties of the Company and the Selling Stockholders
herein, to the performance by the Company


                                     - 22 -

and the Selling Stockholders of their respective obligations hereunder and to
the following additional conditions:

            (a) The Registration Statement shall have become effective not later
than 2:00 P.M., San Francisco time, on the date following the date of this
Agreement, or such later date as shall be consented to in writing by you; and no
stop order suspending the effectiveness thereof shall have been issued and no
proceedings for that purpose shall have been initiated or, to the knowledge of
the Company, any Selling Stockholder or any Underwriter, threatened by the
Commission, and any request of the Commission for additional information (to be
included in the Registration Statement or the Prospectus or otherwise) shall
have been complied with to the satisfaction of Underwriters' Counsel.

            (b) All corporate proceedings and other legal matters in connection
with this Agreement, the form of Registration Statement and the Prospectus, and
the registration, authorization, issue, sale and delivery of the Shares, shall
have been reasonably satisfactory to Underwriters' Counsel, and such counsel
shall have been furnished with such papers and information as they may
reasonably have requested to enable them to pass upon the matters referred to in
this Section.

            (c) Subsequent to the execution and delivery of this Agreement and
prior to the Closing Date, or any later date on which Option Shares are to be
purchased, as the case may be, there shall not have been any change in the
condition (financial or otherwise), earnings, operations, business or business
prospects of the Company and its subsidiaries considered as one enterprise from
that set forth in the Registration Statement or Prospectus, which, in your sole
judgment, is material and adverse and that makes it, in your sole judgment,
impracticable or inadvisable to proceed with the public offering of the Shares
as contemplated by the Prospectus.

            (d) You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, the
following opinion of counsel for the Company and the Selling Stockholders, dated
the Closing Date or such later date on which Option Shares are to be purchased
addressed to the Underwriters and with reproduced copies or signed counterparts
thereof for each of the Underwriters, to the effect that:

                  (i) The Company and each subsidiary has been duly incorporated
            and is validly existing as a corporation in good standing under the
            laws of the jurisdiction of its incorporation;

                  (ii) The Company and each subsidiary has the corporate power

                                     - 23 -
<PAGE>   24

                  (iii) The Company and each subsidiary is duly qualified to do
            business as a foreign corporation and is in good standing in each
            jurisdiction, if any, in which the ownership or leasing of its
            properties or the conduct of its business requires such
            qualification, except where the failure to be so qualified or be in
            good standing would not have a material adverse effect on the
            condition (financial or otherwise), earnings, operations or business
            of the Company and its subsidiaries considered as one enterprise. To
            such counsel's knowledge, the Company does not own or control,
            directly or indirectly, any corporation, association or other entity
            other than those subsidiaries listed in Exhibit 21 to the Company's

            Statement;

                  (iv) The authorized, issued and outstanding capital stock of
            the Company is as set forth in the Prospectus under the caption
            "Capitalization" as of the dates stated therein, the issued and
            outstanding shares of capital stock of the Company (including the
            Option Shares to be sold by the Selling Stockholders) have been duly
            and validly issued and are fully paid and nonassessable, and, to
            such counsel's knowledge, will not have been issued in violation of
            or subject to any preemptive right, co-sale right, registration
            right, right of first refusal or other similar right;

                  (v) All issued and outstanding shares of capital stock of each
            subsidiary of the Company have been duly authorized and validly
            issued and are fully paid and nonassessable, and, to such counsel's
            knowledge, have not been issued in violation of or subject to any
            preemptive right, co-sale right, registration right, right of first
            refusal or other similar right and are owned by the Company free and
            clear of any pledge, lien, security interest, encumbrance, claim or
            equitable interest;

                  (vi) The Shares to be issued by the Company pursuant to the
            terms of this Agreement have been duly authorized and, upon issuance
            and delivery against payment therefor in accordance with the terms
            hereof, will be duly and validly issued and fully paid and
            nonassessable, and will not have been issued in violation of or
            subject to any preemptive right, co-sale right, registration right,
            right of first refusal or other similar right.

                  (vii) The Company has the corporate power and authority to
            enter into this Agreement and to issue, sell and deliver to the
            Underwriters the Shares to be issued and sold by it hereunder;

                  (viii) This Agreement has been duly authorized by all
            necessary corporate action on the part of the Company and has been
            duly executed


                                     - 24 -
<PAGE>   25

            and delivered by the Company and, assuming due authorization,
            execution and delivery by you, is a valid and binding agreement of
            the Company, enforceable in accordance with its terms, except
            insofar as indemnification provisions may be limited by applicable
            law and except as enforceability may be limited by bankruptcy,
            insolvency, reorganization, moratorium or similar laws relating to
            or affecting creditors' rights generally or by general equitable
            principles;

                  (ix) The Registration Statement has become effective under the
            Act and, to such counsel's knowledge, no stop order suspending the
            effectiveness of the Registration Statement has been issued and no
            proceedings for that purpose have been instituted or are pending or
            threatened under the Act;

                  (x) The Registration Statement and the Prospectus, and each
            amendment or supplement thereto (other than the financial statements
            (including supporting schedules) and financial data derived
            therefrom as to which such counsel need express no opinion), as of
            the effective date of the Registration Statement, complied as to
            form in all material respects with the requirements of the Act and
            the applicable Rules and Regulations;

                  (xi) The information in the Prospectus under the caption
            "Description of Capital Stock, " to the extent that it constitutes
            matters of law or legal conclusions, has been reviewed by such
            counsel and is a fair summary of such matters and conclusions; and
            the forms of certificates evidencing the Common Stock and filed as
            exhibits to the Registration Statement comply with Delaware law;

                  (xii) The description in the Registration Statement and the
            Prospectus of the charter and bylaws of the Company and of statutes
            are accurate and fairly present the information required to be
            presented by the Act and the applicable Rules and Regulations;

                  (xiii) To such counsel's knowledge, there are no agreements,
            contracts, leases or documents to which the Company is a party of a
            character required to be described or referred to in the

            the Registration Statement which are not described or referred to
            therein or filed as required;

                  (xiv) The performance of this Agreement and the consummation
            of the transactions herein contemplated (other than performance of
            the Company's indemnification obligations hereunder, concerning
            which no opinion need be expressed) will not (A) result in any
            violation of the


                                     - 25 -
<PAGE>   26

            Company's charter or bylaws, or (B) to such counsel's knowledge,
            result in a material breach or violation of any of the terms and
            provisions of, or constitute a default under, any bond, debenture,
            note or other evidence of indebtedness, or any lease, contract,
            indenture, mortgage, deed of trust, loan agreement, joint venture or
            other agreement or instrument known to such counsel to which the
            Company is a party or by which its properties are bound, or any
            applicable statute, rule or regulation known to such counsel or, to
            such counsel's knowledge, any order, writ or decree of any court,
            government or governmental agency or body having jurisdiction over
            the Company or any of its subsidiaries, or over any of their
            properties or operations;

                  (xv) No consent, approval, authorization or order of or
            qualification with any court, government or governmental agency or
            body having jurisdiction over the Company or any of its
            subsidiaries, or over any of their properties or operations is
            necessary in connection with the consummation by the Company of the
            transactions herein contemplated, except such as have been obtained
            under the Act or such as may be required under state or other
            securities or Blue Sky laws in connection with the purchase and the
            distribution of the Shares by the Underwriters;

                  (xvi) To such counsel's knowledge, there are no legal or
            governmental proceedings pending or threatened against the Company
            or any of its subsidiaries of a character required to be disclosed
            in the Registration Statement or the Prospectus by the Act or the
            Rules and Regulations, other than those described therein;

                  (xvii) To such counsel's knowledge, neither the Company nor
            any of its subsidiaries is presently (a) in material violation of
            its respective charter or bylaws, or (b) in material breach of any
            applicable statute, rule or regulation known to such counsel or, to
            such counsel's knowledge, any order, writ or decree of any court or
            governmental agency or body having jurisdiction over the Company or
            any of its subsidiaries, or over any of their properties or
            operations; and

                  (xviii) To such counsel's knowledge, except as set forth in
            the Registration Statement and Prospectus, no holders of Common
            Stock or other securities of the Company have registration rights
            with respect to securities of the Company and, except as set forth
            in the Registration Statement and Prospectus, all holders of
            securities of the Company having rights known to such counsel to
            registration of such shares of Common Stock or other securities,
            because of the filing of the Registration Statement by the Company
            have, with respect to the offering contemplated thereby, waived such
            rights or such rights have expired by reason of lapse


                                     - 26 -
<PAGE>   27

            of time following notification of the Company's intent to file the
            Registration Statement or have included securities in the
            Registration Statement pursuant to the exercise of and in full
            satisfaction of such rights;

                  (xix) Each Selling Stockholder which is not a natural person
            has full right power and authority to enter into and to perform its
            obligations under the Power of Attorney and Custody Agreement to be
            executed and delivered by it in connection with the transactions
            contemplated herein; the Power of Attorney and Custody Agreement of
            each Selling Stockholder that is not a natural person has been duly
            authorized by such Selling Stockholder; the Power of Attorney and
            Custody Agreement of each Selling Stockholder has been duly executed
            and delivered by or on behalf of such Selling Stockholder; and the
            Power of Attorney and Custody Agreement of each Selling Stockholder
            constitutes the valid and binding agreement of such Selling
            Stockholder, enforceable in accordance with its terms, except as the
            enforcement thereof may be limited by bankruptcy, insolvency,
            reorganization, moratorium or other similar laws relating to or
            affecting creditors' rights generally or by general equitable
            principles;

                  (xx) Each of the Selling Stockholders has full right, power
            and authority to enter into and to perform its obligations under
            this Agreement and to sell, transfer, assign and deliver the Option
            Shares to be sold by such Selling Stockholder hereunder;

                  (xxi) This Agreement has been duly authorized by each Selling
            Stockholder that is not a natural person and has been duly executed
            and delivered by or on behalf of each Selling Stockholder; and

                  (xxii) Upon the delivery of and payment for the Option Shares
            as contemplated in this Agreement, each of the Underwriters will
            receive valid marketable title to the Option Shares purchased by it
            from such Selling Stockholder, free and clear of any pledge, lien,
            security interest, encumbrance, claim or equitable interest. In
            rendering such opinion, such counsel may assume that the
            Underwriters are without notice of any defect in the title of the
            Option Shares being purchased from the Selling Stockholders.

            In addition, such counsel shall state that such counsel has
participated in conferences with officials and other representatives of the
Company, the Representatives, Underwriters' Counsel and the independent
certified public accountants of the Company, at which such conferences the
contents of the Registration Statement and Prospectus and related matters were
discussed, and although they have not verified the accuracy or completeness of
the statements contained in the Registration Statement or the Prospectus,


                                     - 27 -
<PAGE>   28

nothing has come to the attention of such counsel which leads them to believe
that, at the time the Registration Statement became effective and at all times
subsequent thereto up to and on the Closing Date and on any later date on which
Option Shares are to be purchased, the Registration Statement and any amendment
or supplement thereto (other than the financial statements including supporting
schedules and other financial and statistical information derived therefrom, as
to which such counsel need express no comment) contained any untrue statement of
a material fact or omitted to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, or at the
Closing Date or any later date on which the Option Shares are to be purchased,
as the case may be, the Registration Statement, the Prospectus and any amendment
or supplement thereto (except as aforesaid) contained any untrue statement of a
material fact or omitted to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. Such counsel shall also state that the conditions for the
use of Form SB-2 have been satisfied.

            Counsel rendering the foregoing opinion may rely as to questions of
law not involving the laws of the United States or the State of New Jersey, New
York and Delaware upon opinions of local counsel, and as to questions of fact
upon representations or certificates of officers of the Company, the Selling
Stockholders or officers of the Selling Stockholders (when the Selling
Stockholder is not a natural person), and of government officials, in which case
their opinion is to state that they are so relying and that they have no
knowledge of any material misstatement or inaccuracy in any such opinion,
representation or certificate. Copies of any opinion, representation or
certificate so relied upon shall be delivered to you, as Representatives of the
Underwriters, and to Underwriters' Counsel.

            (e) You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, an opinion
of Alston & Bird LLP, in form and substance satisfactory to you, with respect to
the sufficiency of all such corporate proceedings and other legal matters
relating to this Agreement and the transactions contemplated hereby as you may
reasonably require, and the Company shall have furnished to such counsel such
documents as they may have requested for the purpose of enabling them to pass
upon such matters.

            (f) You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, a letter
from BDO Seidman, LLP addressed to the Underwriters, dated the Closing Date or
such later date on which Option Shares are to be purchased, as the case may be,
confirming that they are independent certified public accountants with respect
to the Company within the meaning of the Act and the applicable published Rules
and Regulations and based upon the procedures described in such letter delivered
to you concurrently with the execution of this Agreement (herein called the
"Original Letter"), but carried out to a date not more than five (5) business
days prior to the Closing Date or such later date on which Option Shares are to
be purchased, as the case may be, (i) confirming, to the extent true, that the


                                     - 28 -
<PAGE>   29

statements and conclusions set forth in the Original Letter are accurate as of
the Closing Date or such later date on which Option Shares are to be purchased,
as the case may be, and (ii) setting forth any revisions and additions to the
statements and conclusions set forth in the Original Letter which are necessary
to reflect any changes in the facts described in the Original Letter since the
date of such letter, or to reflect the availability of more recent financial
statements, data or information. The letter shall not disclose any change in the
condition (financial or otherwise), earnings, operations, business or business
prospects of the Company and its subsidiaries considered as one enterprise from
that set forth in the Registration Statement or Prospectus, which, in your sole
judgment, is material and adverse and that makes it, in your sole judgment,
impracticable or inadvisable to proceed with the public offering of the Shares
as contemplated by the Prospectus. The Original Letter from BDO Seidman, LLP
shall be addressed to or for the use of the Underwriters in form and substance
satisfactory to the Underwriters and shall (i) represent, to the extent true,
that they are independent certified public accountants with respect to the
Company within the meaning of the Act and the applicable published Rules and
Regulations, (ii) set forth their opinion with respect to their examination of
the consolidated balance sheet of the Company as of December 31, 1996 and
related consolidated statements of operations, stockholders' equity, and cash
flows for the twelve (12) months ended December 3l, 1996, (iii) state that BDO
Seidman, LLP has performed the procedures set out in Statement on Auditing
Standards No. 71 ("SAS71") for a review of interim financial information and
providing the report of BDO Seidman, LLP as described in SAS71 on the financial
statements for each of the quarters in the six month period ended June 30, 1996
(the "Quarterly Financial Statements"), (iv) state that in the course of such
review, nothing came to their attention that leads them to believe that any
material modifications need to be made to any of the Quarterly Financial
Statements in order for them to be in compliance with generally accepted
accounting principles consistently applied across the periods presented, and (v)
address other matters agreed upon by BDO Seidman, LLP and you. In addition, you
shall have received from BDO Seidman, LLP a letter addressed to the Company and
made available to you for the use of the Underwriters stating that their review
of the Company's system of internal accounting controls, to the extent they
deemed necessary in establishing the scope of their examination of the Company's
consolidated financial statements as of December 3l, 1996, did not disclose any
weaknesses in internal controls that they considered to be material weaknesses.

            (g) You shall have received on the Closing Date and on any later
date on which Option Shares are to be purchased, as the case may be, a
certificate of the Company, dated the Closing Date or such later date on which
Option Shares are to be purchased, as the case may be, signed by the Chief
Executive Officer and Chief Financial Officer of the Company, to the effect
that, and you shall be satisfied that:

                  (i) The representations and warranties of the Company in this
            Agreement are true and correct, as if made on and as of the Closing
            Date or any later date on which Option Shares are to be purchased,
            as the case


                                     - 29 -
<PAGE>   30

            may be, and the Company has complied with all the agreements and
            satisfied all the conditions on its part to be performed or
            satisfied at or prior to the Closing Date or any later date on which
            Option Shares are to be purchased, as the case may be;

                  (ii) No stop order suspending the effectiveness of the
            Registration Statement has been issued and no proceedings for that
            purpose have been instituted or are pending or threatened under the
            Act;

                  (iii) When the Registration Statement became effective and at
            all times subsequent thereto up to the delivery of such certificate,
            the Registration Statement and the Prospectus, and any amendments or
            supplements thereto, contained all material information required to
            be included therein by the Act and the Rules and Regulations and in
            all material respects conformed to the requirements of the Act and
            the Rules and Regulations, the Registration Statement, and any
            amendment or supplement thereto, did not and does not include any
            untrue statement of a material fact or omit to state a material fact
            required to be stated therein or necessary to make the statements
            therein not misleading, the Prospectus, and any amendment or
            supplement thereto, did not and does not include any untrue
            statement of a material fact or omit to state a material fact
            necessary to make the statements therein, in the light of the
            circumstances under which they were made, not misleading, and, since
            the effective date of the Registration Statement, there has occurred
            no event required to be set forth in an amended or supplemented
            Prospectus which has not been so set forth; and

                  (iv) Subsequent to the respective dates as of which
            information is given in the Registration Statement and Prospectus,
            there has not been (A) any material adverse change in the condition
            (financial or otherwise), earnings, operations, business or business
            prospects of the Company and its subsidiaries considered as one

certificate, dated the Closing Date, or any later date on which Option Shares
are to be purchased, as the case may be, from the Attorneys for each Selling
Stockholder to the effect that, as of the Closing Date, or any later date on
which Option Shares are to be purchased, as the case may be, they have not been
informed that:

                  (i) The representations and warranties made by such Selling
            Stockholder herein are not true or correct in any material respect
            on the Closing Date or on any later date on which Option Shares are
            to be purchased, as the case may be; or

                  (ii) Such Selling Stockholder has not complied with any
            obligation or satisfied any condition which is required to be
            performed or satisfied on the part of such Selling Stockholder at or

            (i) The Company shall have obtained and delivered to you an
agreement from each officer and director of the Company, each Selling
Stockholder and each of [Austin W. Marxe and Janney, Montgomery Scott, Inc.] in
writing prior to the date hereof that such person will not, during the Lock-up
Period, effect the Disposition of any Securities now owned or hereafter acquired

gifts, provided the donee or donees thereof agree in writing to be bound by this

respect to any Securities or with respect to any security (other than a
broad-based market basket or index) that includes, relates to or derives any
significant part of its value from Securities. Furthermore, such person will

the Company's transfer agent against the transfer of the Securities held by such

            (j) The Company and the Selling Stockholders shall have furnished to
you such further certificates and documents as you shall reasonably request
(including certificates of officers of the Company, the Selling Stockholders or
officers of the Selling Stockholders (when the Selling Stockholder is not a
natural person) as to the accuracy of the representations and warranties of the
Company and the Selling Stockholders herein, as to the performance by the
Company and the Selling Stockholders of their respective obligations hereunder
and as to the other conditions concurrent and precedent to the obligations of
the Underwriters hereunder.

            All such opinions, certificates, letters and documents will be in
compliance with the provisions hereof only if they are reasonably satisfactory
to Underwriters' Counsel. The Company and the Selling Stockholders will furnish
you with such number of conformed copies of such opinions, certificates, letters
and documents as you shall reasonably request.

      7. Option Shares.

            (a) On the basis of the representations, warranties and agreements
herein contained, but subject to the terms and conditions herein set forth, the
Company and the Selling Stockholders, severally but not jointly, hereby grant to
the several Underwriters, for the purpose of covering over-allotments in
connection with the distribution and sale of the Firm Shares only, a
nontransferable option to purchase up to the respective number of Option Shares
set forth opposite the names of the Company and the Selling Stockholders in
Schedule B hereto at the purchase price per share for the Firm Shares set forth
in Section 3 hereof. Such option may be exercised by the Representatives on
behalf of the several Underwriters on one (1) or more occasions in whole or in
part during the period of thirty (30) days after the date on which the Firm
Shares are initially offered to the public, by giving written notice to the
Company. The number of Option Shares to be purchased by each Underwriter upon
the exercise of such option shall be the same proportion of the total number of
Option Shares to be purchased by the several Underwriters pursuant to the
exercise of such option as the number of Firm Shares purchased by such
Underwriter (set forth in Schedule A hereto) bears to the total number of Firm
Shares purchased by the several Underwriters (set forth in Schedule A hereto),
adjusted by the Representatives in such manner as to avoid fractional shares.
[Priority of purchases if less than all Option Shares are to be purchased?????]

            Delivery of definitive certificates for the Option Shares to be
purchased by the several Underwriters pursuant to the exercise of the option
granted by this Section 7 shall be made against payment of the purchase price
therefor by the several Underwriters by certified or official bank check or
checks drawn in next-day funds, payable to the order of the Company with regard
to the Option Shares being purchased from the Company, and to the order of the
Custodian for the respective accounts of the Selling Stockholders with regard to
the Option Shares being purchased from such Selling Stockholders (and the
Company and such Selling Stockholders agree not to deposit and to


                                     - 32 -
<PAGE>   33

cause the Custodian not to deposit any such check in the bank on which it is
drawn, and not to take any other action with the purpose or effect of receiving
immediately available funds, until the business day following the date of its
delivery to the Company or the Custodian, as the case may be, and in the event
of any breach of the foregoing, the Company or the Selling Stockholders, as the
case may be, shall reimburse the Underwriters for the interest lost and any
other expenses borne by them by reason of such breach). Such delivery and
payment shall take place at the offices of Lowenstein, Sandler, Kohl, Fisher &
Boylan, P.A., 65 Livingston Avenue, Roseland, New Jersey 07068, or at such other
place as may be agreed upon among the Representatives, the Company and the
Attorneys (i) on the Closing Date, if written notice of the exercise of such
option is received by the Company at least two (2) full business days prior to
the Closing Date, or (ii) on a date which shall not be later than the third
(3rd) full business day following the date the Company receives written notice
of the exercise of such option, if such notice is received by the Company less
than two (2) full business days prior to the Closing Date.

            The certificates for the Option Shares to be so delivered will be
made available to you at such office or such other location including, without
limitation, in New York City, as you may reasonably request for checking at
least one (1) full business day prior to the date of payment and delivery and
will be in such names and denominations as you may request, such request to be
made at least two (2) full business days prior to such date of payment and
delivery. If the Representatives so elect, delivery of the Option Shares may be
made by credit through full fast transfer to the accounts at The Depository
Trust Company designated by the Representatives.

            It is understood that you, individually, and not as the
Representatives of the several Underwriters, may (but shall not be obligated to)
make payment of the purchase price on behalf of any Underwriter or Underwriters
whose check or checks shall not have been received by you prior to the date of
payment and delivery for the Option Shares to be purchased by such Underwriter
or Underwriters. Any such payment by you shall not relieve any such Underwriter
or Underwriters of any of its or their obligations hereunder.

      The certificates in negotiable form for the Option Shares to be sold by
the Selling Stockholders have been placed in custody (for delivery under this
Agreement) under the Custody Agreements. Each Selling Stockholder agrees that
the certificates for the Option Shares of such Selling Stockholder so held in
custody are subject to the interests of the Underwriters hereunder, that the
arrangements made by such Selling Stockholder for such custody, including the
Power of Attorney, is to that extent irrevocable and that the obligations of
such Selling Stockholder hereunder shall not be terminated by the act of such
Selling Stockholder or by operation of law, whether by the death or incapacity
of such Selling Stockholder or the occurrence of any other event, except as
specifically provided herein or in the applicable Custody Agreement. If any
Selling Stockholder should die or be incapacitated, or if any other such event
should occur, before the delivery


                                     - 33 -
<PAGE>   34

of the certificates for the Option Shares to be sold by such Selling Stockholder
hereunder, the Option Shares to be sold by such Selling Stockholder shall,
except as specifically provided herein or in the applicable Custody Agreement,
be delivered by the Custodian in accordance with the terms and conditions of
this Agreement as if such death, incapacity or other event had not occurred,
regardless of whether the Custodian shall have received notice of such death or
other event.

            (b) Upon exercise of any option provided for in Section 7(a) hereof,
the obligations of the several Underwriters to purchase such Option Shares will
be subject (as of the date hereof and as of the date of payment and delivery for
such Option Shares) to the accuracy of and compliance with the representations,
warranties and agreements of the Company and the Selling Stockholders herein, to
the accuracy of the statements of the Company, the Selling Stockholders and
officers of the Company made pursuant to the provisions hereof, to the
performance by the Company and the Selling Stockholders of their respective
obligations hereunder, to the conditions set forth in Section 6 hereof, and to
the condition that all proceedings taken at or prior to the payment date in
connection with the sale and transfer of such Option Shares shall be
satisfactory in form and substance to you and to Underwriters' Counsel, and you
shall have been furnished with all such documents, certificates and opinions as
you may request in order to evidence the accuracy and completeness of any of the
representations, warranties or statements, the performance of any of the
covenants or agreements of the Company and the Selling Stockholders or the
satisfaction of any of the conditions herein contained.

      8. Indemnification and Contribution

            (a) The Company agrees to indemnify and hold harmless each
Underwriter against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject (including, without
limitation, in its capacity as an Underwriter or as a "qualified independent
underwriter" within the meaning of Schedule E of the Bylaws of the NASD), under
the Act, the Exchange Act or otherwise, specifically including, but not limited
to, losses, claims, damages or liabilities (or actions in respect thereof)
arising out of or based upon (i) any breach of any representation, warranty,
agreement or covenant of the Company herein contained, (ii) any untrue statement
or alleged untrue statement of any material fact contained in the Registration
Statement or any amendment or supplement thereto, or the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or (iii) any untrue
statement or alleged untrue statement of any material fact contained in any
Preliminary Prospectus or the Prospectus or any amendment or supplement thereto,
or the omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading, and agrees to
reimburse each Underwriter for any legal or other expenses reasonably incurred
by it in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the Company shall not be
liable in any such


                                     - 34 -
<PAGE>   35

case to the extent that any such loss, claim, damage, liability or action arises
out of or is based upon an untrue statement or alleged untrue statement or
omission or alleged omission made in the Registration Statement, such
Preliminary Prospectus or the Prospectus, or any such amendment or supplement
thereto, in reliance upon, and in conformity with, written information relating
to any Underwriter furnished to the Company by such Underwriter, directly or
through you, specifically for use in the preparation thereof and, provided
further, that the indemnity agreement provided in this Section 8(a) with respect
to any Preliminary Prospectus shall not inure to the benefit of any Underwriter
from whom the person asserting any losses, claims, damages, liabilities or
actions based upon any untrue statement or alleged untrue statement of material
fact or omission or alleged omission to state therein a material fact purchased
Shares, if a copy of the Prospectus in which such untrue statement or alleged
untrue statement or omission or alleged omission was corrected had not been sent
or given to such person within the time required by the Act and the Rules and
Regulations, unless such failure is the result of noncompliance by the Company
with Section 4(d) hereof.

            The indemnity agreement in this Section 8(a) shall extend upon the
same terms and conditions to, and shall inure to the benefit of, each person, if
any, who controls any Underwriter within the meaning of the Act or the Exchange
Act. This indemnity agreement shall be in addition to any liabilities which the
Company may otherwise have.

            (b) Each Selling Stockholder, severally and not jointly, agrees to
indemnify and hold harmless each Underwriter against any losses, claims, damages
or liabilities, joint or several, to which such Underwriter may become subject
(including, without limitation, in its capacity as an Underwriter or as a
"qualified independent underwriter" within the meaning of Schedule E or the
Bylaws of the NASD) under the Act, the Exchange Act or otherwise, specifically
including, but not limited to, losses, claims, damages or liabilities (or
actions in respect thereof) arising out of or based upon (i) any breach of any
representation, warranty, agreement or covenant of such Selling Stockholder
herein contained, (ii) any untrue statement or alleged untrue statement of any
material fact contained in the Registration Statement or any amendment or
supplement thereto, or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or (iii) any untrue statement or alleged untrue
statement of any material fact contained in any Preliminary Prospectus or the
Prospectus or any amendment or supplement thereto, or the omission or alleged
omission to state therein a material fact necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, in the case of subparagraphs (ii) and (iii) of this Section 8(b) to
the extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company or such Underwriter
by such Selling Stockholder, directly or through such Selling Stockholder's
representatives, specifically for use in the preparation thereof, and agrees to
reimburse each Underwriter for any legal or other


                                     - 35 -
<PAGE>   36

expenses reasonably incurred by it in connection with investigating or defending
any such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement provided in this Section 8(b) with respect to any
Preliminary Prospectus shall not inure to the benefit of any Underwriter from
whom the person asserting any losses, claims, damages, liabilities or actions
based upon any untrue statement or alleged untrue statement of a material fact
or omission or alleged omission to state therein a material fact purchased
Shares, if a copy of the Prospectus in which such untrue statement or alleged
untrue statement or omission or alleged omission was corrected had not been sent
or given to such person within the time required by the Act and the Rules and
Regulations, unless such failure is the result of noncompliance by the Company
with Section 4(d) hereof.

            The indemnity agreement in this Section 8(b) shall extend upon the
same terms and conditions to, and shall inure to the benefit of, each person, if
any, who controls any Underwriter within the meaning of the Act or the Exchange
Act. This indemnity agreement shall be in addition to any liabilities which such
Selling Stockholder may otherwise have.

            (c) Each Underwriter, severally and not jointly, agrees to indemnity
and hold harmless the Company and each Selling Stockholder against any losses,
claims, damages or liabilities, joint or several, to which the Company or such
Selling Stockholder may become subject under the Act or otherwise, specifically
including, but not limited to, losses, claims, damages or liabilities (or
actions in respect thereof) arising out of or based upon (i) any breach of any
representation, warranty, agreement or covenant of such Underwriter herein
contained, (ii) any untrue statement or alleged untrue statement of any material
fact contained in the Registration Statement or any amendment or supplement
thereto, or the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or (iii) any untrue statement or alleged untrue statement of any
material fact contained in any Preliminary Prospectus or the Prospectus or any
amendment or supplement thereto, or the omission or alleged omission to state
therein a material fact necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading, in the case of
subparagraphs (ii) and (iii) of this Section 8(c) to the extent, but only to the
extent, that such untrue statement or alleged untrue statement or omission or
alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by such Underwriter, directly or through
you, specifically for use in the preparation thereof, and agrees to reimburse
the Company and each such Selling Stockholder for any legal or other expenses
reasonably incurred by the Company and each such Selling Stockholder in
connection with investigating or defending any such loss, claim, damage,
liability or action.

            The indemnity agreement in this Section 8(c) shall extend upon the
same terms and conditions to, and shall inure to the benefit of, each officer of
the Company who signed the Registration Statement and each director of the
Company, each Selling


                                     - 36 -
<PAGE>   37

Stockholder and each person, if any, who controls the Company or any Selling
Stockholder within the meaning of the Act or the Exchange Act. This indemnity
agreement shall be in addition to any liabilities which each Underwriter may
otherwise have.

            (d) Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
shall, if a claim in respect thereof is to be made against any indemnifying
party under this Section 8, notify the indemnifying party in writing of the
commencement thereof but the omission so to notify the indemnifying party will
not relieve it from any liability which it may have to any indemnified party
otherwise than under this Section 8. In case any such action is brought against
any indemnified party, and it notified the indemnifying party of the
commencement thereof, the indemnifying party will be entitled to participate
therein and, to the extent that it shall elect by written notice delivered to
the indemnified party promptly after receiving the aforesaid notice from such
indemnified party, to assume the defense thereof, with counsel reasonably
satisfactory to such indemnified party; provided, however, that if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that there may be legal defenses available to it and/or other indemnified
parties which are different from or additional to those available to the
indemnifying party, the indemnified party or parties shall have the right to
select separate counsel to assume such legal defenses and to otherwise
participate in the defense of such action on behalf of such indemnified party or
parties. Upon receipt of notice from the indemnifying party to such indemnified
party of the indemnifying party's election so to assume the defense of such
action and approval by the indemnified party of counsel, the indemnifying party
will not be liable to such indemnified party under this Section 8 for any legal
or other expenses subsequently incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that the indemnifying party shall not be liable
for the expenses of more than one separate counsel (together with appropriate
local counsel) approved by the indemnifying party representing all the
indemnified parties under Section 8(a), 8(b) or 8(c) hereof who are parties to
such action), (ii) the indemnifying party shall not have employed counsel
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of commencement of the action or (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying parry. In no event shall any
indemnifying party be liable in respect of any amounts paid in settlement of any
action unless the indemnifying party shall have approved the terms of such
settlement; provided that such consent shall not be unreasonably withheld. No
indemnifying party shall, without the prior written consent of the indemnified
party, effect any settlement of any pending or threatened proceeding in respect
of which any indemnified party is or could have been a party and indemnification
could have been sought hereunder by such indemnified party, unless such
settlement


                                     - 37 -
<PAGE>   38

includes an unconditional release of such indemnified party from all liability
on all claims that are the subject matter of such proceeding.

            (e) In order to provide for just and equitable contribution in any
action in which a claim for indemnification is made pursuant to this Section 8
but it is judicially determined (by the entry of a final judgment or decree by a
court of competent jurisdiction and the expiration of time to appeal or the
denial of the last right of appeal) that such indemnification may not be
enforced in such case notwithstanding the fact that this Section 8 provides for
indemnification in such case, all the parties hereto shall contribute to the
aggregate losses, claims, damages or liabilities to which they may be subject
(after contribution from others) in such proportion so that, except as set forth
in Section 8(f) hereof, the Underwriters severally and not jointly are
responsible pro rata for the portion represented by the percentage that the
underwriting discount bears to the initial public offering price, and the
Company and the Selling Stockholders are responsible for the remaining portion,
provided, however, that (i) no Underwriter shall be required to contribute any
amount in excess of the amount by which the underwriting discount applicable to
the Shares purchased by such Underwriter exceeds the amount of damages which
such Underwriter has otherwise required to pay and (ii) no person guilty of a
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who is not guilty of such
fraudulent misrepresentation. The contribution agreement in this Section 8(e)
shall extend upon the same terms and conditions to, and shall inure to the
benefit of, each person, if any, who controls any Underwriter, the Company or
any Selling Stockholder within the meaning of the Act or the Exchange Act and
each officer of the Company who signed the Registration Statement and each
director of the Company.

            (f) The liability of each Selling Stockholder under the
representations, warranties and agreements contained herein and under the
indemnity agreements contained in the provisions of this Section 8 shall be
limited to an amount equal to the initial public offering price of the Selling
Stockholder Shares sold by such Selling Stockholder to the Underwriters minus
the amount of the underwriting discount paid thereon to the Underwriters by such
Selling Stockholder. The Company and such Selling Stockholders may agree, as
among themselves and without limiting the rights of the Underwriters under this
Agreement, as to the respective amounts of such liability for which they each
shall be responsible.

            (g) The parties to this Agreement hereby acknowledge that they are
sophisticated business persons who were represented by counsel during the
negotiations regarding the provisions hereof including, without limitation, the
provisions of this Section 8, and are fully informed regarding said provisions.
They further acknowledge that the provisions of this Section 8 fairly allocate
the risks in light of the ability of the parties to investigate the Company and
its business in order to assure that adequate disclosure is made in the
Registration Statement and Prospectus as required by the Act and the Exchange
Act.

      9. Representations, Warranties, Covenants and Agreements to Survive
Delivery. All representations, warranties, covenants and agreements of the
Company, the Selling Stockholders and the Underwriters herein or in certificates
delivered pursuant hereto, and the indemnity and contribution agreements
contained in Section 8 hereof shall remain operative and in full force and
effect regardless of any investigation made by or on behalf of any Underwriter
or any person controlling any Underwriter within the meaning of the Act or the
Exchange Act, or by or on behalf of the Company or any Selling Stockholder, or
any of their officers, directors or controlling persons within the meaning of
the Act or the Exchange Act, and shall survive the delivery of the Shares to the
several Underwriters hereunder or termination of this Agreement.

      10. Substitution of Underwriters. If any Underwriter or Underwriters shall
fail to take up and pay for the number of Firm Shares agreed by such Underwriter
or Underwriters to be purchased hereunder upon tender of such Firm Shares in
accordance with the terms hereof, and if the aggregate number of Firm Shares
which such defaulting Underwriter or Underwriters so agreed but failed to
purchase does not exceed 10% of the Firm Shares, the remaining Underwriters
shall be obligated, severally in proportion to their respective commitments
hereunder, to take up and pay for the Firm Shares of such defaulting Underwriter
or Underwriters.

            If any Underwriter or Underwriters so defaults and the aggregate
number of Firm Shares which such defaulting Underwriter or Underwriters agreed
but failed to take up and pay for exceeds 10% of the Firm Shares, the remaining
Underwriters shall have the right, but shall not be obligated, to take up and
pay for (in such proportions as may be agreed upon among them) the Firm Shares
which the defaulting Underwriter or Underwriters so agreed but failed to
purchase. If such remaining Underwriters do not, at the Closing Date, take up
and pay for the Firm Shares which the defaulting Underwriter or Underwriters so
agreed but failed to purchase, the Closing Date shall be postponed for
twenty-four (24) hours to allow the several Underwriters the privilege of
substituting within twenty-four (24) hours (including non-business hours)
another underwriter or underwriters (which may include any nondefaulting
Underwriter) satisfactory to the Company. If no such underwriter or underwriters
shall have been substituted as aforesaid by such postponed Closing Date, the
losing Date may, at the option of the Company, be postponed for a further
twenty-four (24) hours, if necessary, to allow the Company the privilege of
finding another underwriter or underwriters, satisfactory to you, to purchase
the Firm Shares which the defaulting Underwriter or Underwriters so agreed but
failed to purchase. If it shall be arranged for the remaining Underwriters or
substituted underwriter or underwriters to take up the Firm Shares of the
defaulting Underwriter or Underwriters as provided in this Section 10, (i) the
Company shall have the right to postpone the time of delivery for a period of
not more than seven (7) full business days, in order to effect whatever changes
may thereby be made necessary in the Registration Statement or the Prospectus,
or in any other documents or arrangements, and the Company agrees promptly to
file any amendments to the Registration Statement,


                                     - 39 -
<PAGE>   40

supplements to the Prospectus or other such documents which may thereby be made
necessary, and (ii) the respective number of Firm Shares to be purchased by the
remaining Underwriters and substituted underwriter or underwriters shall be
taken as the basis of their underwriting obligation. If the remaining
Underwriters shall not take up and pay for all such Firm Shares so agreed to be
purchased by the defaulting Underwriter or Underwriters or substitute another
underwriter or underwriters as aforesaid and the Company shall not find or shall
not elect to seek another underwriter or underwriters for such Firm Shares as
aforesaid, then this Agreement shall terminate.

            In the event of any termination of this Agreement pursuant to the
preceding paragraph of this Section 10, neither the Company nor any Selling
Stockholder shall be liable to any Underwriter, except as provided in Sections 5
and 8 hereof) nor shall any Underwriter (other than an Underwriter who shall
have failed, otherwise than for some reason permitted under this Agreement, to
purchase the number of Firm Shares agreed by such Underwriter to be purchased
hereunder, which Underwriter shall remain liable to the Company, the Selling
Stockholders and the other Underwriters for damages, if any, resulting from such
default) be liable to the Company or any Selling Stockholder (except to the
extent provided in Sections 5 and 8 hereof).

            (a) This Agreement shall become effective at the earlier of (i) 6:30
A.M., San Francisco time, on the first full business day following the effective
date of the Registration Statement, or (ii) the time of the initial public
offering of any of the Shares by the Underwriters after the Registration
Statement becomes effective. The time of the initial public offering shall mean
the time of the release by you, for publication, of the first newspaper
advertisement relating to the Shares, or the time at which the Shares are first
generally offered by the Underwriters to the public by letter, telephone,
telegram or telecopy, whichever shall first occur. By giving notice as set forth
in Section 12 before the time this Agreement becomes effective, you, as
Representatives of the several Underwriters, or the Company, may prevent this

party, except as provided in Sections 4(j), 5 and 8 hereof.

            (b) You, as Representatives of the several Underwriters, shall have
the right to terminate this Agreement by giving notice as hereinafter specified
at any time on or prior to the Closing Date or on or prior to any later date on
which Option Shares are to be purchased, as the case may be, (i) if the Company
or any Selling Stockholder shall have failed, refused or been unable to perform
any agreement on its part to be performed, or because any other condition of the
Underwriters' obligations hereunder required to be fulfilled is not fulfilled,
including, without limitation, any change in the condition

(financial or otherwise), earnings, operations, business or business prospects
of the Company and its subsidiaries considered as one enterprise from that set
forth in the Registration Statement or Prospectus, which, in your sole judgment,
is material and adverse, or (ii) if additional material governmental
restrictions, not in force and effect on the date hereof, shall have been
imposed upon trading in securities generally or minimum or maximum prices shall
have been generally established on the New York Stock Exchange or on the
American Stock Exchange or in the over the counter market by the NASD, or
trading in securities generally shall have been suspended on either such
exchange or in the over the counter market by the NASD, or if a banking
moratorium shall have been declared by federal, New York or California
authorities, or (iii) if the Company shall have sustained a loss by strike,
fire, flood, earthquake, accident or other calamity of such character as to
interfere materially with the conduct of the business and operations of the
Company regardless of whether or not such loss shall have been insured, or (iv)
if there shall have been a material adverse change in the general political or
economic conditions or financial markets as in your reasonable judgment makes it
inadvisable or impracticable to proceed with the offering, sale and delivery of
the Shares, or (v) if there shall have been an outbreak or escalation of
hostilities or of any other insurrection or armed conflict or the declaration by
the United States of a national emergency which, in the reasonable opinion of
the Representatives, makes it impracticable or inadvisable to proceed with the
public offering of the Shares as contemplated by the Prospectus. In the event of
termination pursuant to subparagraph (i) above, the Company shall remain
obligated to pay costs and expenses pursuant to Sections 4(j), 5 and 8 hereof.
Any termination pursuant to any of subparagraphs (ii) through (v) above shall be
without liability of any party to any other party except as provided in Sections
5 and 8 hereof.

terminate this Agreement as provided in this Section 11, you shall promptly
notify the Company by telephone, telecopy or telegram, in each case confirmed by
letter. If the Company shall elect to prevent this Agreement from becoming
effective, the Company shall promptly notify you by telephone, telecopy or
