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

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES
 
     The following information relates to securities of the Company issued or
sold within the past three years which were not registered under the Securities
Act (all share and per share amounts have been adjusted to reflect the
one-for-four reverse stock split of the Company's common stock, $.01 par value
(the "Common Stock") effected on September 25, 1995):
 
          (i) On July 10, 1996 the Company issued an aggregate amount of
     $1,000,000 of its 6% subordinated convertible debentures, due 1997 (the
     "Debentures") to institutional and private investors and members of
     management for an aggregate purchase price of $1,000,000. This transaction
     was completed without registration under the Securities Act of the
     Debentures or the shares of Common Stock into which such Debentures are
     convertible in reliance upon exemptions provided by Section 4(2) of the
     Securities Act. There were no underwriters for this issuance.
 
          (ii) On June 30, 1995 the Company issued an aggregate of 28 units,
     each unit consisting of 2,500 shares of Common Stock and a five-year
     warrant to purchase 2,500 shares of Common Stock at $2.00 per share (a
     "Unit"), to private investors and members of management, for an aggregate
     purchase price of $168,000. This transaction was completed without
     registration under the Securities Act of the shares of Common Stock or the
     warrants comprising the Units or the shares of Common Stock underlying the
     warrants in reliance upon the exemptions provided by Section 4(2) of the
     Securities Act. There were no underwriters for this issuance.
 
          (iii) On May 9, 1995 the Company issued an aggregate of 125 Units and
     one three-year warrant to purchase 37,500 shares of Common Stock at $2.00
     per share, to two institutional investors, for an aggregate purchase price
     of $750,000. This transaction was completed without registration under the
     Securities Act of the shares of Common Stock or the warrants comprising the
     Units, the shares of Common Stock underlying the warrants included in the
     Units, the additional three-year warrant or the shares of Common Stock
     underlying the three-year warrant, in reliance upon the exemptions provided
     by Section 4(2) of the Securities Act. There were no underwriters for this
     issuance.
 
          (iv) At various times between October 1993 and October 1996, the
     Company granted stock options to certain employees of the Company covering
     an aggregate of 434,375 shares of Common Stock. These grants were exempt
     from registration pursuant to Securities Act Release No. 33-6188 (Feb. 1,
     1980). No underwriter was involved in these grants.

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

JANNEY MONTGOMERY SCOTT INC.

Attention: Syndicate Department

Dear Ladies and Gentlemen:

      Barringer Technologies Inc., a Delaware corporation (the "Company"),
proposes to issue and sell to the several underwriters named in Schedule I
hereto (the "Underwriters") 1,250,000 shares of its common stock, par value $.01
per share (the "Common Stock") and 1,250,000 Common Stock Purchase Warrants.
Each such Warrant shall represent the right to acquire one quarter of a share of
Common Stock, shall expire three years from the effective date of the initial
offering unless redeemed prior thereto, shall be exercisable at a price equal to
115% of the offering price per share of Common Stock, and shall contain such
other terms and conditions as are set forth in the related exhibit to the
Registration Statement described below. The 1,250,000 shares of Common Stock to
be purchased by the Underwriters are hereinafter referred to as the "Firm
Shares" and the 1,250,000 Common Stock Purchase Warrants to be purchased by the
Underwriters as the "Firm Warrants". The Firm Shares and Firm Warrants are
hereinafter collectively referred to as the "Firm Securities". In addition, the
Company proposes to grant to the several Underwriters, solely for the purpose of
covering over-allotments in the sale of the Firm Shares, the option described in
Section 5 of this agreement (the "Agreement") to purchase up to 187,500
additional shares of Common Stock (the "Additional Shares") and 187,500
additional Common Stock Purchase Warrants (the "Additional Warrants"). The
Additional Shares and the Additional Warrants are hereinafter collectively
referred to as the "Additional Securities". The Additional Securities may only
be purchased on the basis of one Additional Warrant for each Additional Share
purchased.

      The Firm Securities and the Additional Securities, and the shares of
Common Stock issuable upon exercise of the Firm Warrants and the Additional
Warrants are hereinafter
<PAGE>   2
collectively referred to as the "Offered Securities"; the Offered Securities and
the Representative's Securities (defined below in Section 6 hereof) collectively
as the "Securities"; all the warrants included in the Securities as the
"Warrants" and all of the shares of Common Stock issuable on exercise of the
Warrants as the "Warrant Shares".

      You, as representative of the Underwriters (the "Representative"), have
advised the Company that you and the other Underwriters desire to purchase,
severally and not jointly, the Firm Securities and that you have been authorized
by the Underwriters to execute this Agreement on their behalf. The Company
hereby confirms the agreement made by it with respect to the purchase of the
Firm Securities by the several Underwriters on whose behalf you are signing this
Agreement, as follows:

      1.    REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

      The Company represents and warrants to, and agrees with, each of the
Underwriters that:

            (a) REGISTRATION STATEMENT AND PROSPECTUS. The Company has filed
      with the Securities and Exchange Commission ("Commission") a registration
      statement on Form SB-2 (No. 333-13703) for the registration under the
      Securities Act of 1933, as amended ("Securities Act"), of the Securities,
      and may have filed one or more amendments thereto, copies of which have
      heretofore been delivered to you. The registration statement, including
      the prospectus, financial statements and exhibits, when it shall become
      effective, and such additional information, if any, with respect to the
      offering permitted to be omitted from such registration statement when it
      becomes effective if subsequently filed with the Commission pursuant to
      Rule 430A of the General Rules and Regulations of the Commission under the
      Securities Act (the "Rules under the Securities Act"), is hereinafter
      called the "Registration Statement" and the final prospectus included as
      part of the Registration Statement is herein called the "Prospectus",
      except that, if any revised prospectus shall be provided to the
      Underwriters by the Company for use in connection with the offering of the
      Securities which differs from the Prospectus on file at the Commission at
      the time the Registration Statement becomes effective (whether or not such
      revised prospectus is required to be filed by the Company pursuant to Rule
      424(b) of the Rules under the Securities Act), the term "Prospectus" shall
      refer to such revised prospectus from and after the time it is first
      provided to the Underwriters for such use. The term "Preliminary
      Prospectus" as used in this Agreement means a preliminary prospectus as
      defined in Rule 430 of the Rules under the Securities Act. The Securities
      Act, the Securities Exchange Act of 1934, as amended ("Exchange Act"), and
      the rules and regulations promulgated thereunder are sometimes
      collectively referred to in this Agreement as the "Acts." All contracts
      and documents required by the Acts to be filed or submitted in connection
      with the Registration Statement have been so filed or submitted.


                                        2
<PAGE>   3
            (b) COMPLIANCE WITH SECURITIES ACT, ETC. When the Registration
      Statement shall become effective and at all times subsequent thereto, up
      to and including the Closing Date and the Option Closing Date (as such
      terms are herein defined), and during such longer period until any
      post-effective amendment to the Registration Statement shall become
      effective, the Registration Statement (and any post-effective amendment to
      the Registration Statement) will contain all statements which are required
      to be stated therein in accordance with the Securities Act and the Rules
      under the Securities Act, will fully comply as to form in all material
      respects with the applicable provisions of the Securities Act and the
      Rules under the Securities Act, and the Registration Statement and any
      post-effective amendment to the Registration Statement will not contain
      any untrue statement of a material fact and will not omit to state any
      material fact required to be stated therein or necessary in order to make
      the statements therein not misleading; and the Prospectus and any
      amendment or supplement thereto will at all times up to and including the
      Closing Date and the Option Closing Date (as hereinafter defined), and
      during such longer period as the Prospectus may be required to be
      delivered in connection with sales of Securities by the Underwriters or
      any dealer, fully comply in all material respects with the provisions of
      the Securities Act and the Rules under the Securities Act and will not
      contain any untrue statement of a material fact and will not omit to state
      any material fact required to be stated therein or necessary in order to
      make the statements therein, in the light of the circumstances under which
      they were made, not misleading; provided, however, that the Company makes
      no representations or warranties as to the information contained in or
      omitted from the Registration Statement and any post-effective amendment
      to the Registration Statement or the Prospectus or any amendment of, or
      supplement to, either of them in reliance upon and in conformity with
      information furnished in writing to the Company by or on behalf of any
      Underwriter through the Representative specifically for use in connection
      with the preparation of the Registration Statement or of the Prospectus.
      It is understood that for all purposes of this Agreement the statements
      set forth in the Prospectus on page 2 with respect to stabilization, the
      second and third sentences of the last paragraph under "Certain
      Relationships and Related Transactions" with respect to the transactions
      with officers of the Representative under the section entitled
      "Underwriting" and the identity of counsel for the Underwriters under the
      section entitled "Legal Matters" constitute the only information furnished
      in writing by or on behalf of the Underwriters for inclusion in the
      Registration Statement and Prospectus.

            (c) NO STOP ORDER. The Commission has not issued any order
      preventing or suspending the use of any Preliminary Prospectus, and each
      Preliminary Prospectus, at the time of filing thereof, fully complied in
      all material respects with the provisions of the Securities Act and the
      Rules under the Securities Act and did not include any untrue statement of
      a material fact or omit to state any material fact required to be stated
      therein or necessary in order to make the statements therein, in the light
      of the circumstances under which they were made, not misleading; provided,
      however, that the Company makes no representations or warranties as to


                                        3
<PAGE>   4
      the information contained in or omitted from any Preliminary Prospectus in
      reliance upon and in conformity with information furnished in writing to
      the Company by or on behalf of any Underwriter through the Representative
      specifically for use in connection with the preparation of such
      Preliminary Prospectus.

            (d) ACCOUNTANTS. BDO Seidman, LLP has audited the audited financial
      statements filed as part of the Registration Statement and those included
      in the Prospectus, to the extent set forth in their reports in the
      Registration Statement and Prospectus, and are independent certified
      public accountants with respect to the Company as required by the
      Securities Act and the Rules under the Securities Act.

            (e) FINANCIAL STATEMENTS. The consolidated financial statements and
      the notes thereto included in the Registration Statement and Prospectus
      comply as to form in all material respects with the applicable accounting
      requirements of the Securities Act and the Rules under the Securities Act.
      The consolidated financial statements present fairly the financial
      condition and results of operations and combined cash flows of the Company
      and its consolidated subsidiaries, at the dates and for the periods
      indicated therein, and have been prepared in conformity with generally
      accepted accounting principles applied on a consistent basis throughout
      the periods involved (except as disclosed in the notes thereto). The
      financial information set forth in the Prospectus under the headings
      "Summary Consolidated Financial Information", "Recent Developments" and
      "Selected Consolidated Financial Data" present fairly, on the basis stated
      in the Prospectus, the information set forth therein and has been derived
      from or compiled on a basis consistent with that of the audited
      consolidated financial statements included in the Prospectus.

            The Companies (as defined below) maintain a system of internal
      accounting controls sufficient to provide reasonable assurance that (i)
      transactions are executed in accordance with management's general or
      specific authorization; (ii) transactions are recorded as necessary to
      permit preparation of financial statements in conformity with generally
      accepted accounting principles and to maintain accountability for assets;
      (iii) access to assets is permitted only in accordance with management's
      general or specific authorization; and (iv) the recorded accountability
      for assets is compared with the existing assets at reasonable intervals
      and appropriate action is taken with respect to any difference.

            (f) SUBSIDIARIES; COMMONLY CONTROLLED ENTITIES. The Company owns all
      of the outstanding shares of capital stock of Barringer Instruments, Inc.,
      a Delaware corporation ("BII"), and of Barringer Research Ltd., an
      Ontario, Canada corporation ("BRL"; collectively, the "Subsidiaries") and
      26% of the capital stock of Barringer Laboratories, Inc., a 
      corporation ("Labco"). All the outstanding shares of Capital Stock of 
      each of the Subsidiaries have been duly authorized and validly issued, 
      are fully paid and non-assessable and all the shares of capital stock of 
      BII and BRL and                 shares of Labco are owned beneficially 
      by the Company, free and clear of any liens, encumbrances, security 
      interests or other restrictions, except 

                                        4
<PAGE>   5
      restrictions created pursuant to the Stock Purchase Agreement (the "Stock
      Purchase Agreement"), dated December 1, 1995, between the Company and
      Labco and the Termination Agreement (the "Termination Agreement"), dated
      October 1996, between the Company and Labco, and no rights exist to
      acquire any of the capital stock of any of the Subsidiaries, except those
      included in the Stock Purchase Agreement and the Termination Agreement.
      Neither the Company, nor any of its Subsidiaries owns any securities of

      the Companies is a party or by which any of their respective properties or
      assets are bound other than such conflicts, breaches, violations or
      defaults which, singly or in the aggregate, would not result in a Material
      Adverse Change, nor will such action result in any violation of the
      provisions of the charter or bylaws of any of the Companies, or any law,
      rule, regulation, judgment, order or decree of any government,
      governmental instrumentality or court having jurisdiction over any of the

      violations, which, singly or in the aggregate, would not result in a
      Material Adverse Change, or (ii) require the consent, approval,
      authorization or order of any court or governmental agency or body for the
      consummation by the Company of any of the transactions contemplated
      hereby, except such as have been obtained and such as may be required
      under the Acts, and under state securities or "Blue Sky" laws in
      connection with the issuance and distribution of the Securities or except

<PAGE>   8

      Securities Act or the Rules that have not been so filed.

            (m) LITIGATION. Except as set forth in the Prospectus, there is no
      action, suit or proceeding before or by any court or governmental agency
      or body, domestic or foreign, now pending or, to the knowledge of the
      Company, threatened, against or affecting any of the Companies, that is
      required to be disclosed in the Registration Statement (other than as
      disclosed therein), or that might result in a Material Adverse Change or
      that might materially and adversely affect the properties or assets
      thereof or that might materially or adversely affect the consummation of
      this Agreement; all pending legal or governmental proceedings to which any
      of the Companies is a party or of which any of their respective properties
      or assets are the subject, that are not described in the Registration
      Statement, including ordinary routine litigation incidental to the
      business of the Companies, are not material.

            (n) PAYMENT OF TAXES. Each of the Companies has filed all United
      States federal, state and local tax returns which are required to be filed
      and all such filed returns are complete and accurate except for such
      incompletions and inaccuracies as would not result in a Material Adverse
      Change. All taxes and all assessments to the extent that they have become
      due have been paid in full or the Company has contested such amounts
      through appropriate proceedings and has established adequate reserves
      therefor in accordance with generally accepted accounting principles, and
      each of them has made adequate accruals for all taxes which may be owed
      but have not been paid. There is no audit, examination, deficiency, or
      refund litigation pending or, to the Company's knowledge, threatened, with
      respect to any Taxes of the Companies that would individually or in the
      aggregate result in a Material Adverse Change. All Taxes, interest,
      additions, and penalties due with respect to completed and settled
      examinations or concluded litigation relating to it have been paid in
      full. None of the Companies has executed an extension or waiver of any
      statute of limitations on the assessment or collection of any Tax that is
      currently in effect. No rulings have been issued by or agreements entered
      into with any Tax Authority (as defined below) with respect to the Company
      or any subsidiary or affiliate. For purposes of this paragraph, "Taxes"
      shall mean all taxes, charges, fees, liens, duties or other assessments,
      however denominated, including any interest or penalties that may become
      payable in respect thereof, imposed by the United States government, any
      state, local or foreign government or any agency or political subdivision
      of any such government (a "Taxing Authority"), which taxes shall include,
      without limiting the generality of the foregoing, all income taxes,
      payroll and employee withholding taxes, unemployment insurance taxes,
      social security taxes, sales and use taxes, excise taxes, capital taxes,
      franchise taxes, gross receipt taxes, occupation taxes, real or personal
      property taxes, value added taxes, stamp taxes, transfer taxes, workers'
      compensation taxes, and other obligations of the same or of a similar
      nature.

      National Market System.

            (p) INVESTMENT COMPANY STATUS. None of the Companies are an
      "investment company" or an "affiliated person" of, or promoter, or
      "principal underwriter" for, an "investment company," as such terms are
      defined in the Investment Company Act of 1940.

            (q) REAL AND PERSONAL PROPERTY. Except as disclosed in the
      Prospectus, each of the Companies owns outright, in fee simple, title to
      the real and personal property purported to be owned by it, free and clear
      of all liens, mortgages, charges or encumbrances of any nature, except
      those which do not materially diminish the value of the property subject
      to them or materially interfere with or materially impair the present and
      continued use of that property in the usual and normal conduct of its
      business (collectively "Permitted Encumbrances"). All of the leases under
      which each of the Companies holds properties or assets as lessee are in
      all material respects as described in the Prospectus, are valid and in
      full force and effect and, to the Companies' knowledge, enforceable as to
      the Companies in accordance with their terms, and none of the Companies is
      in default in any respect under any of the terms or provisions of any such
      leases, except for any default which would not result in a Material
      Adverse Change and, to the Company's knowledge, no claim has been asserted
      by anyone adverse to the rights of the Companies as lessee under any of
      the leases mentioned above, or affecting or questioning the right of any
      of the Companies to continued possession of the leased premises or assets
      under any such lease that would result in a Material Adverse Change.

            (r) INTELLECTUAL PROPERTY. Each of the Companies owns or possesses
      adequate licenses or other rights to use all patents, trade secrets,
      trademarks, trade names and copyrights necessary to enable it to conduct
      its business as now operated (the "Intellectual Property") except for such
      licenses or other rights, which the failure of the Company to own of
      possess would not result in a Material Adverse Change and such
      Intellectual Property (other than Intellectual Property rights acquired as
      licensee) is owned free and clear of any liens, security interests,
      mortgages, charges, encumbrances and adverse rights of every kind, nature
      and description; and none of the Companies has any knowledge of any claim
      or received any notice of infringement of or conflict with asserted rights
      of others or have knowledge of infringement by others of its rights with
      respect to any of the foregoing which, singly or in the aggregate, could
      result in a Material Adverse Change . Except for the rights of customers
      under license agreements, the Intellectual Property is not subject to any
      licenses, sublicenses, royalty arrangements, or disputes, and except for
      such rights, each of the Companies has the exclusive right to make, copy,
      sell, exploit and provide to others the use of the Intellectual Property
      pertinent to it and all derivative works thereof free and clear of any
      liens, security interests, mortgages, charges, encumbrances and adverse
      rights of every kind, nature and description. There are no defects in the
      Intellectual Property, which defects would in any material and


                                        9
<PAGE>   10
      adverse respect affect the functioning thereof in accordance with the
      specifications therefor, or the use or exploitation thereof. No agreement
      exists which would preclude any desired change to the Intellectual
      Property, excluding Permitted Encumbrances. Each of the Companies has
      taken or is taking all actions necessary in its reasonable judgment to
      protect the Intellectual Property pertinent to it. Except as disclosed in
      the Prospectus, no third party has any interest in, or right to
      compensation from any of the Companies by reason of the use, exploitation
      or sale of the Intellectual Property, and none of the Companies has
      received notice or knowledge of any complaint, assertion, threat or
      allegation that would contradict the foregoing.

            (s) INSURANCE. Each of the Companies has its property adequately
      insured against loss or damage by fire, maintains adequate insurance
      against liability for negligence, and maintains such other insurance in
      such nature and amounts of coverage as is usually maintained by companies
      engaged in the same or similar business.

            (t) NO STABILIZATION OR MANIPULATION OF PRICE. Neither the Company
      nor any officer or director of the Company has taken or will take,
      directly or indirectly, any action designed to stabilize or manipulate the
      price of any security of the Company, or which has constituted or which
      might in the future reasonably be expected to constitute stabilization or
      manipulation of the price of the Offered Securities in connection with the
      offering contemplated by the Registration Statement.

            (u) RELATED TRANSACTIONS. There are no business relationships or
      related-party transactions of the nature described in Item 404 of
      Regulation S-B involving any of the Companies and any other persons
      referred to in said Item 404 that are required to be described in the
      Prospectus and which have not been so described.

            (v) NO REGISTRATION RIGHTS. Except as set forth in Schedule __
      hereto, no person or entity has the right (which has not been waived) to
      require registration of Common Stock or other securities of the Company
      because of the filing or effectiveness of the Registration Statement or
      otherwise.

            (w) LOCK-UP AGREEMENTS. The Company has obtained and delivered to
      the Underwriters a written agreement, in form satisfactory to Rosenman &
      Colin LLP, counsel for the Underwriters, by each officer and director of
      the Company as of the Effective Date not to, directly or indirectly, sell,
      offer to sell or agree to sell or otherwise dispose of any Common Stock of
      the Company for a period of 180 days from the Effective Date without the
      prior written consent of the Representative, other than pursuant to the
      Registration Statement or as described in such agreement.

<PAGE>   11
            (x) NO BROKER OR FINDER ENGAGED BY THE COMPANY. Except as disclosed
      in the Prospectus, the Company has not incurred any liability for any
      finder's fees or similar payments in connection with any of the
      transactions herein contemplated.

            (y) LABOR RELATIONS. None of the Companies is involved in any labor
      dispute which might reasonably be expected to result in a Material Adverse
      Change nor, to the knowledge of the Companies, is any such dispute
      threatened.

            (z) DEALINGS. None of the Companies nor any of their respective
      officers, directors, employees, agents or any other person acting on their
      behalf has, directly or indirectly, given or agreed to give any money,
      gift or similar benefit (other than legal price concessions to customers
      in the ordinary course of business) to any customer, supplier, employee or
      an agent of a customer or supplier, or official or employee of any
      governmental agency or instrumentality of any government (domestic or
      foreign) or any political party or candidate for office (domestic or
      foreign) or other person who was, is, or may be in a position to help or
      hinder their respective businesses (or assist in connection with any
      actual or proposed transaction) which (a) might subject any of them to any
      damage or penalty in any civil, criminal or governmental litigation or
      proceeding, (b) if not given in the past, might result in a Material
      Adverse Change as reflected in any of the combined financial statements
      contained in the Prospectus, or (c) if not continued in the future, would
      reasonably be expected to result in a Material Adverse Change. Each of the
      Companies' internal accounting controls and procedures are sufficient to
      cause it to comply with the Foreign Corrupt Practices Act of 1977, as
      amended.

            (aa) PRIOR TRANSACTIONS. Except as set forth in the Registration
      Statement, the Company has not issued, sold or offered for sale within the

Prospectus, the Company hereby grants an option to the Underwriters to purchase
150,000 Additional Shares and 150,000 Additional Warrants from the Company, in

by the Underwriters as to all or any part of the Additional Securities at any
time, but only once prior to the end of the close of business on the thirtieth
day following the Closing Date; provided, however, that Additional Securities
may only be purchased on the basis of one Additional Warrant for each Additional
Share purchased. Subject to such adjustments to eliminate fractional Additional
Securities as you, as the Representative of the Underwriters, may determine, the

Representative of the Underwriters, by giving written notice to the Company
setting forth the number of Additional Securities to be purchased, the date and
time for delivery of payment for the Additional Securities, and stating that the
Additional Securities being purchased are to be used solely for the purpose of

<PAGE>   13
after the day on which the notice is given. In either event, the date shall not
be more than fifteen (15) full business days after the day on which the notice
is given. The date and time for delivery and payment is called the "Option
Closing Date." Upon exercise of the option, the Company shall become obligated
to sell to the Underwriters and, subject to the terms and conditions set forth
in Section 4(c) of this Agreement, the Underwriters shall become obligated,
severally and not jointly, to purchase the number of Additional Shares described

      8. FURTHER COVENANTS OF THE COMPANY. In further consideration of the
agreements of the Underwriters contained in this Agreement, the Company
covenants and agrees with each of the several Underwriters as follows:

            (a) The Company will not at any time submit or make any amendment or
      supplement to the Prospectus or Registration Statement which shall not
      have been submitted to you within a reasonable time prior to the proposed
      submission thereof, or to which you shall reasonably object in writing, or
      which is not in compliance with the Acts.

            (b) The Company will use its best efforts to cause the Registration
      Statement and any post-effective amendments thereto to comply with the
      requirements of the Securities Act and the Rules under the Securities Act
      and to become effective, and will promptly advise you and confirm in
      writing upon your request (i) when the Registration Statement and any
      amendment thereto shall become effective, (ii) when any post-effective
      amendment to the Registration Statement becomes effective, (iii) of the
      receipt of any comments from the Commission, (iv) when the Commission
      shall request any amendment to the Registration Statement or Prospectus,
      or request any additional information, (v) of the necessity


                                       14
<PAGE>   15
      of amending or supplementing the Registration Statement or any
      post-effective amendment in order to then meet the requirements of the
      Securities Act and the Rules under the Securities Act, and (vi) of the
      issuance by the Commission, any "Blue Sky" authority or any other
      governmental agency with jurisdiction over the Company or its securities,
      of any stop order or similar order with regard to the Registration
      Statement or the Prospectus, or any order preventing or suspending the use
      of any Preliminary Prospectus or the Registration Statement or Prospectus,
      or of the suspension of the qualification of the Securities for offer or
      sale in any jurisdiction, or of the institution of any proceedings for any
      such purpose. The Company will use its best efforts to prevent the
      issuance of any stop order or of any order preventing or suspending such
      use and if such an order shall be issued, the Company will use its best
      efforts to obtain its withdrawal as soon as possible.

            (c) The Company will prepare and file with the Commission, upon your
      reasonable request, any amendments or supplements to the Registration
      Statement or Prospectus, in form and substance reasonably satisfactory to
      counsel for the Company, as in the opinion of Rosenman & Colin LLP,
      counsel for the Underwriters, may be necessary or advisable in connection
      with the distribution of the Offered Securities and the exercise of the
      Warrants included therein, and will use its best efforts to cause the same
      to become effective as promptly as possible and to remain effective for
      the term of the Warrants included in the Offered Securities.

            (d) The Company consents to the use of any Preliminary Prospectus by
      the several Underwriters and by dealers for the purposes contemplated by
      this Agreement and in accordance with the Acts. The Company will deliver
      to you, at or before the Closing Date, three copies of the Registration
      Statement and all amendments thereto, including all financial statements
      and exhibits filed with it, and copies of all written communications
      between the Company, its representatives and agents and the Commission,
      and will deliver to you such number of copies of the Registration
      Statement, including such financial statements, but without exhibits, and
      all amendments thereto as you may reasonably request. The Company will
      deliver or mail to you and, upon your request, to the Underwriters, from
      time to time, during the period when delivery of the Prospectus relating
      to the Offered Securities shall be required under the Acts, as many copies
      of the Prospectus (as amended or supplemented) as you may reasonably
      request.

            (e) If, at the time that the Registration Statement becomes
      effective, any information shall have been omitted therefrom in reliance
      upon Rule 430A of the Rules under the Securities Act, then, at the times
      specified in Rule 430A and Rule 424(b), the Company will prepare, and file
      or transmit for filing with the Commission in accordance with such Rule
      430A and Rule 424(b) of the Rules under the Securities Act copies of the
      amended Prospectus, or, if required by such Rule 430A, a post-effective
      amendment to the Registration Statement (including an amended Prospectus)
      containing all information so omitted.

            (f) The Company will comply with the requirements of the Acts and
      any other applicable rules and regulations of any governmental authority
      having


                                       15
<PAGE>   16
      jurisdiction over this offering so as to permit the completion of the
      public distribution of the Offered Securities. Subject to the provisions
      of Subsection (a) of this Section 8, if, at any time when a Prospectus is
      required to be delivered under the Acts, (i) an event relating to or
      affecting the Company shall have occurred which, in the judgment of the
      Company and its counsel, or in the opinion of counsel for the
      Underwriters, would cause the Registration Statement as then in effect to
      include an untrue statement of a material fact or to omit to state a
      material fact required to be stated therein or necessary in order to make
      the statements therein not misleading, or in order to make the
      Registration Statement comply with the Acts and the Rules under the
      Securities Act, or (ii) it is necessary to amend or supplement the
      Registration Statement or Prospectus, the Company will promptly notify you
      of the occurrence and will promptly prepare, file and deliver to you
      without charge such number of copies of the amended or supplemented
      Registration Statement or Prospectus as you shall reasonably request, and
      will use its best efforts to cause the Commission and appropriate "Blue
      Sky" authorities to take all required action with regard to any such
      amendment as may be necessary to permit the lawful use of the Registration
      Statement and Prospectus in connection with the distribution of the
      Offered Securities.

            (g) The Company will supply all necessary documents, exhibits and
      information and execute all applications, instruments and papers as may be
      necessary or desirable in the opinion of Rosenman & Colin LLP, Blue Sky
      counsel, and as requested by you, to qualify the Offered Securities for
      sale under the Blue Sky or other securities laws in such jurisdictions as
      the Underwriters may reasonably request, provided the Company shall not
      have to qualify as a foreign corporation and shall not be required to
      consent to service of process generally. The Company will take any
      reasonable measures requested by you and such action, if any, which is
      necessary under such laws in order to qualify the Offered Securities for
      sale and to continue such registration or qualification so long as
      necessary to permit the completion of the public distribution with respect
      to such Securities.

            (h) The Company will make generally available to its security
      holders as soon as practicable after the expiration of one year after the
      date the Registration Statement becomes effective, and in all events not
      later than      , 1997, an earnings statement of the Company (which will 
      be in such detail and form as you may reasonably request and which need 
      not be audited) covering a period of at least 12 months beginning not 
      later than the first day of the Company's fiscal quarter next following 
      the date the Registration Statement becomes effective, which earnings 
      statement shall satisfy the provision of Section 11(a) of the Securities 
      Act including Rule 158 promulgated thereunder.

            (i) So long as the Company shall be subject to the reporting
      requirements of the Exchange Act, the Company shall furnish to its
      stockholders and warrantholders annual reports containing financial
      statements of the Company audited by its independent certified public
      accountants and quarterly reports for the first three quarters of its
      fiscal year containing financial information which may be unaudited.


                                       16
<PAGE>   17
            (j) So long as the Company shall be subject to the reporting
      requirements of the Exchange Act, the Company will, from time to time,
      after the date the Registration Statement becomes effective, file with the
      Commission such reports as are required by the Acts and with state
      securities commissions in states where the Offered Securities have been
      sold by the Representative (as the Representative shall have advised the
      Company in writing) such reports as are required to be filed by the
      securities acts and the regulations of those states.

            (k) The Company will apply the net proceeds from the sale of the
      Offered Securities for the purposes set forth under "Use of Proceeds" in
      the Prospectus.

            (l) The Company shall furnish to you as early as practicable prior
      to the Closing Date, but no later than three (3) full business days prior
      thereto, a copy of the latest available unaudited interim financial
      statements of the Company which have been read by the Company's
      independent certified public accountants, as stated in their letters to be
      furnished pursuant to Section 11(i) of this Agreement.

            (m) During the period of five (5) years from the date the
      Registration Statement becomes effective, the Company will furnish to the
      Representative copies of all reports and other communications (financial
      or other) furnished by the Company to its shareholders and, as soon as
      reasonably practicable, copies of any reports or financial statements
      furnished or filed by the Company to or with the Commission, NASDAQ, or
      any national exchange on which any class of securities of the Company may
      be listed.

            (n) During a period of 180 days after the date the Registration
      Statement becomes effective, the Company will not, directly or indirectly,
      without the prior written consent of the Representative, offer, sell,
      grant any option to purchase or otherwise dispose of any Common Stock or
      any securities convertible into or exchangeable for Common Stock except
      pursuant to this Agreement, and except (i) in connection with a merger or
      asset acquisition, (ii) upon exercise or conversion of securities
      (including stock options) of the Company outstanding prior to the
      effective date of the Registration Statement (iii) the creation and
      adoption of an employee stock compensation program (a "Program"), or (iv)
      the grant of options, SARs, restricted stock and other securities under
      such Program, not to exceed 200,000 shares of Common Stock.

            (o) The Company will reasonably enforce, for your benefit, the
      written agreements (copies of which have been furnished to you) by all of
      the executive officers and directors of the Company pursuant to Section 
      1(w) hereof.

            (p) The Company will cause the officers and directors of the Company
      (enumerate) to enter into an agreement with the Representative to the
      effect that, for a period of 180 days from the date hereof, he or she will
      not, without the prior consent of the Representative, directly or
      indirectly, offer, sell, offer to sell, grant any option to purchase or
      otherwise sell or dispose of any shares of the Common Stock of the Company
      or any securities convertible into or exercisable or exchangeable


                                       17
<PAGE>   18
      therefor or with respect to which such person has the power of
      disposition, except for the exercise of stock options.

            (q) The Prospectus and any amendment or supplement thereto will at
      all times up to and including the Closing Date and the Option Closing Date
      (as hereinafter defined), and during such longer period as the Prospectus
      may be required to be delivered in connection with the issuance and sale
      by the Company of shares of Common Stock or exercise of any of the
      Warrants fully comply in all material respects with the provisions of the
      Securities Act and the Rules under the Securities Act and will not contain
      any untrue statement of a material fact and will not omit to state any
      material fact required to be stated therein or necessary in order to make
      the statements therein, in the light of the circumstances under which they
      were made, not misleading.

      9.    INDEMNIFICATION.

      (a) The Company agrees to indemnify and hold harmless, and, subject to
Section 9(c) to indemnify and hold harmless, each Underwriter (including
specifically each person who may be substituted for an Underwriter as provided
in Section 13 of this Agreement) and each person, if any, who controls any
Underwriter within the meaning of Section 15 of the Securities Act, from and
against any and all losses, claims, damages, expenses or liabilities, joint or
several, to which they or any of them may become subject under the Act, state
securities laws or under any other statute or at common law or otherwise, and,
except as hereinafter provided, will reimburse each of the Underwriters and each
such controlling person, if any, for any legal or other out-of-pocket expenses
reasonably incurred by them or any of them in connection with investigating or
defending any claim or action whether or not resulting in any liability, insofar
as such losses, claims, damages, expenses, liabilities or actions arise out of
or are based upon any untrue statement or alleged untrue statement of a material
fact contained in the Registration Statement, in any Preliminary Prospectus or
in the Prospectus (or the Registration Statement or Prospectus as from time to
time amended or supplemented by the Company) or in any application or other
document (hereinafter "Application") executed by the Company or based upon
written information furnished by or on behalf of the Company, filed in any
jurisdiction in order to qualify the Securities under the securities laws of
that jurisdiction, or which arise out of or are based upon the omission or
alleged omission to state in any of the foregoing any material fact required to
be stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not misleading; provided,
however, that the indemnity agreement contained in this Subsection shall not
apply to any loss, claim, damage, expense or liability to the extent arising out
of any untrue statement or alleged untrue statement or omission or alleged
omission made in the Registration Statement, Preliminary Prospectus or
Prospectus (or the Registration Statement or Prospectus as from time to time
amended or supplemented by the Company) or, Application in reliance upon and in
conformity with information furnished in writing to the Company in connection
therewith by the Representative or any Underwriter directly or through you
expressly for use therein; provided, further that the indemnity agreement
contained in this Subsection is subject to the condition that, insofar as it
relates to any such untrue statement or alleged untrue statement or omission or
alleged omission in any Preliminary Prospectus but


                                       18
<PAGE>   19
eliminated or remedied in the Prospectus, such indemnity agreement shall not
inure to the benefit of any Underwriter or any person controlling such
Underwriter from whom the person asserting any such loss, claim, damage,
expense, liability or action purchased the Securities if (i) prior to the time
such Prospectus was required under the Securities Act to be furnished to such
person the Company had furnished copies of the properly corrected or
supplemental Prospectus to such Underwriter, (ii) a copy of such Prospectus, as
then corrected or supplemented, was not furnished to such person at or prior to
the time required under the Securities Act, and (iii) the delivery of such
Prospectus would have constituted a complete defense to the claim asserted by
such person. Promptly after receipt by any Underwriter or any person controlling
such Underwriter of notice of the commencement of any action in respect of which
indemnity may be sought against the Company under this Subsection (a), such
Underwriter or controlling person shall notify the Company in writing of the
commencement of the action and, subject to the provisions hereinafter stated,
the Company shall assume the defense of that action (including the employment of
counsel who shall be reasonably satisfactory to the Representative (who may be
Company counsel)) and the payment of reasonable out-of-pocket expenses insofar
as such action shall relate to any alleged liability in respect of which
indemnity may be sought against the Company. Any Underwriter or any such
controlling person shall have the right to employ separate counsel in any such
action and participate in the defense, but the fees and expenses of such counsel
shall not be at the expense of the Company unless the employment of such counsel
has been specifically authorized by the Company or unless the indemnified party
or parties reasonably conclude there may be defenses available to it or them
which were not available to the Company (in which case the Company will not have
the right to direct the defense of the action on behalf of the indemnified
parties), in which event the reasonable expenses of one additional counsel for
the Underwriters will be borne by the Company. The Company shall not be liable
to indemnify any person for any settlement of any such action effected without
the written consent of the Company. The obligations of the Company under the
indemnity agreement set forth in this Subsection (a) shall be in addition to any
liability the Company may otherwise have under this Agreement.

      (b) Each Underwriter (including specifically each person who may be
substituted for an Underwriter as provided in Section 13 of this Agreement)
severally agrees to indemnify and hold harmless the Company, each of its
directors, each of its officers and each person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act, from and against
any and all losses, claims, damages, expenses, or liabilities, joint or several,
to which they or any of them may become subject under the Acts or under any
other statute or at common law or otherwise, and, except as hereinafter
provided, will reimburse the Company and each such director, officer or
controlling person for any legal or other out-of-pocket expenses reasonably
incurred by them or any of them in connection with investigating or defending
any claim or action whether or not resulting in any liability, insofar as such
losses, claims, damages, expenses, liabilities or actions arise out of or are
based upon any untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement, in any Preliminary Prospectus or in the
Prospectus (or the Registration Statement or Prospectus as from time to time
amended or supplemented) or in any Application, or arise out of or are based
upon the omission or alleged omission to state a material fact required to be
stated therein or necessary in order to make the statements therein, in the
light of the circumstances under which they were made, not


                                       19
<PAGE>   20
misleading, but only insofar as any such statement or omission was made in
reliance upon and in conformity with information furnished in writing to the
Company in connection therewith by the Representative or such Underwriter
directly or through the Representative expressly for use therein. Promptly after
receipt of notice of the commencement of any action in respect of which
indemnity may be sought against one or more Underwriters under this Subsection
(b), the indemnified party shall notify the Representative Underwriters in
writing of the commencement of the action and the Underwriter or Underwriters
against whom indemnity may be sought shall, subject to the provisions
hereinafter stated, assume the defense of such action (including the employment
of counsel who shall be reasonably satisfactory to the Company, and the payment
of expenses) and the payment of reasonable out-of-pocket expenses insofar as
such action shall relate to an alleged liability in respect of which indemnity
may be sought against such Underwriter or Underwriters. The Company and each
such director, officer or controlling person shall have the right to employ
separate counsel in any such action and participate in the defense, but the fees
and expenses of such counsel shall not be at the expense of any Underwriter
unless the employment of such counsel has been specifically authorized by the
Underwriters obligated to defend such action, unless the indemnified party or
parties reasonably conclude there may be defenses available to it or them which
are not available to the Underwriters against whom indemnification is sought (in
which case those Underwriters will not have the right to direct the defense of
the action on behalf of the indemnified party or parties), in which event the
reasonable out-of-pocket expenses of one additional counsel for all the
indemnified parties will be borne by the indemnifying Underwriters. The
Underwriter against whom indemnity may be sought shall not be liable to
indemnify any person for any settlement of any action effected without such
Underwriter's written consent. The obligations of each Underwriter under the
indemnity agreement set forth in this Subsection (b) shall be in addition to any
liability each of them may otherwise have under this Agreement.

      10. CONTRIBUTION. In order to provide for just and equitable contribution
in circumstances in which the indemnity agreement provided for in Section 9 is
for any reason held to be unenforceable by the indemnified parties although
applicable in accordance with its terms, the Company and the Underwriters shall
contribute to the aggregate losses, claims, damages, liabilities and expenses of
the nature contemplated by said indemnity agreement incurred by the Company, and
one or more of the Underwriters, as incurred, in such proportions that the
Underwriters are responsible for that portion represented by the percentage that
the underwriting discount appearing on the cover page of the Prospectus bears to
the public offering price appearing thereon, and the Company shall be
responsible for the balance; provided, however, that no person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. Notwithstanding the provisions of
this Section 10, no Underwriter shall be required to contribute any amount in
excess of the amount by which the total price at which the Firm Securities and
Additional Securities underwritten by it and distributed to the public were
offered to the public exceeds the amount of any damages of the kind described in
Section 9(a) which such Underwriter has otherwise paid in respect of such
losses, claims, damages, liabilities and expenses. For purposes of this Section,
each person, if any, who controls an Underwriter within the meaning of Section
15 of the Securities Act shall have the same rights to contribution as such
Underwriter, and each director of the Company, each officer of the Company who


                                       20
<PAGE>   21
signed the Registration Statement, and each person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act shall have the
same rights to contribution as the Company.

      11. CONDITIONS OF OBLIGATIONS OF UNDERWRITERS. The obligations of the
Underwriters to purchase and pay for the Firm Securities and Additional
Securities are subject (as of the date hereof and the Closing Date) to the

      hereof it has no knowledge that any such action is in fact contemplated by

      business or of such character as would result in a Material Adverse
      Change, whether or not that loss is covered by insurance.

            (f) Between the date of this Agreement and the Closing Date, each of

            (g) At the Closing Date, there shall have been delivered to you a
      signed opinion of Lowenstein, Sandler, Kohl, Fisher & Boylan, P.A.
      addressed to the Underwriters, dated as of the Closing Date, in form and
      substance reasonably satisfactory to Rosenman & Colin LLP, counsel for the
      Underwriters, together with a signed or photostatic copy of that opinion
      for each of the other Underwriters, substantially to the effect that:

                  (i) Each of the Company and BII has been duly incorporated and
            is validly existing and in good standing under the laws of its
            jurisdiction of incorporation and has the corporate power and
            authority to own and lease its properties and to conduct its
            business as described in the Registration Statement and Prospectus
            and is duly qualified to do business as a foreign corporation and is
            in good standing in each jurisdiction where, to such counsel's
            knowledge, it owns or leases properties and where the failure to so
            qualify would have a material adverse effect on its earnings,
            business affairs or business prospects.

                  (ii) This Agreement has been duly authorized, executed and
            delivered by the Company. All corporate action required to be taken
            by the Board of Directors of the Company and all action required to
            be taken by the stockholders of the Company, if any, in connection
            with the authorization, issuance and sale of the Securities to be
            sold by the Company as contemplated in the Registration Statement
            and the Prospectus have been duly taken. The Company has the
            requisite power and authority to enter into and consummate this
            Agreement.

                  (iii) Neither the issuance by the Company of the Securities to
            be sold by it under this Agreement, the execution and delivery of
            this Agreement, the undertakings contained in the Registration
            Statement or the Prospectus, the consummation of the transactions
            contemplated in this Agreement or compliance with the terms of this
            Agreement, will conflict with or result in a breach of any of the
            terms or provisions of the Certificate of Incorporation, as amended,
            or the By-laws of the Company, or any material indenture, mortgage,
            deed of trust, note, bank loan or credit agreement or any other


                                       22

            agreement or instrument filed as an exhibit to the Registration
            Statement or to any other filing heretofore made by the Company
            under the Acts, any applicable federal or State law (other than Blue
            Sky laws), rule or regulation, or (without search of any court
            dockets) any judgment, order or decree of any government,
            governmental agency or instrumentality or court having jurisdiction
            over any of the Companies or their respective properties or assets,
            of which such counsel is aware.

                  (iv) To such counsel's knowledge, there are no contracts,
            indentures, mortgages, notes, leases or other instruments or
            agreements required to be described or referred to in the
            Registration Statement or to be filed as exhibits thereto other than
            those described or referred to therein or filed as exhibits thereto;
            the descriptions thereof or references thereto in the Prospectus are
            correct in all material respects and no default exists in the due
            performance or observance of any obligation, agreement, covenant or
            condition contained in any contract, indenture, mortgage, note,
            lease or other instrument or agreement so described, referred to or
            filed.

                  (v) To such counsel's knowledge, the Company has no
            subsidiaries other than as set forth in Section 1(f) hereof. All of
            the outstanding shares of capital stock of each Subsidiary have been
            duly authorized and validly issued, are fully paid and non
            assessable and, as of the Closing Date, are owned beneficially by
            the Company, free and clear of any liens, encumbrances, security
            interests or other restrictions, and no person, firm or corporation
            has the right, upon the passage of time or otherwise, to acquire any
            of the stock of any such Subsidiary.

                  (vi) Except as described in the Prospectus, to such counsel's
            knowledge, the Company and the Subsidiaries hold all material
            licenses, certificates, permits and other evidence of regulatory
            compliance issued by appropriate federal, state or local
            governmental agencies or bodies necessary for the conduct of its
            business as described in the Prospectus.

                  (vii) The Company's authorized capital stock consists of
            7,000,000 shares of Common Stock, par value $.01 per share,
            1,000,000 shares of Convertible Preferred Stock, par value $1.25 per
            share, and 4,000,000 shares of Preferred Stock, par value $2.00 per
            share.

                  (viii) The outstanding stock options and warrants relating to
            the Common Stock have been duly authorized and validly issued.

                  (ix) The certificates for the Securities are in proper form
            and comply with Delaware law.

                  (x) The Firm Shares and Additional Shares to be sold by the
            Company as contemplated by this Agreement have been duly authorized,
            and, when issued as provided in this Agreement and any warrant
            agreement relating


                                      23
<PAGE>   24
            thereto upon the due exercise of the Warrants, including the payment
            of the exercise price therefor, will be validly issued, fully paid
            and non-assessable. The holders of any of the Firm Shares and
            Additional Shares when issued as contemplated pursuant to this
            Agreement and any warrant agreement relating thereto upon the due
            exercise of the Warrants, including the payment of the exercise
            price therefor, will not be subject to personal liability solely by
            reason of being such holders and, to such counsel's knowledge, there
            is no preemptive right of any holder of any securities of the
            Company applicable to [any outstanding share of Common Stock] and no
            preemptive right will be applicable to any of the Firm Shares and
            the Additional Shares to be sold by the Company under this Agreement
            when issued and sold as contemplated in this Agreement and in the
            Registration Statement and the Prospectus.

                  (xi) The Warrants have been duly authorized and, when
            delivered and paid for in accordance with this Agreement will be
            validly issued and will constitute valid and binding obligations of
            the Company in accordance with, and will be exercisable in
            accordance with, their terms; the shares of Common Stock issuable on
            exercise of the Warrants have been duly and validly reserved for
            issuance pursuant to the terms of the Warrants and when duly issued
            and paid for in accordance with the terms of such Warrants, will be
            duly authorized, validly issued, fully paid and nonassessable, and
            the holders will not be subject to personal liability by reason of
            being such holders and such shares will not be subject to the
            preemptive rights of any stockholder of the Company.

                  (xii) Except for registration or qualification under the
            Securities Act or under state securities or Blue Sky laws, no
            authorization, approval, consent or license of any federal, New
            Jersey or Delaware regulatory body or authority is required for the
            valid authorization, issuance, sale and delivery of any of the
            Securities, or, if required, all such authorizations, approvals,
            consents and licenses have been obtained and are in force and
            effect.

                  (xiii) The Registration Statement has become effective, and,
            to such counsel's knowledge, no stop order or similar order has been
            issued with regard to the Registration Statement or the Prospectus,
            and no proceedings for that purpose have been instituted or are
            pending and such counsel has not been notified that any such
            proceedings are contemplated under the Acts or under any Blue Sky or
            other securities laws of any jurisdiction.

                  (xiv) The Registration Statement, the Prospectus and each
            post-effective amendment or supplement thereto complies as to form
            in all material respects with the requirements of the Securities Act
            (except that no opinion shall be expressed as to the financial
            statements, notes related thereto, and other financial or
            statistical data included therein and information supplied by you as
            set forth in Section 1(b) hereof).

<PAGE>   25
                  (xv) Such counsel has acted as counsel for the Company and has
            participated in the preparation of the Registration Statement and
            Prospectus and any post-effective amendments or supplements thereto
            to the date of such opinion and, during the course of such
            representation, no facts have come to the attention of such counsel
            which would lead such counsel to believe that either the
            Registration Statement or the Prospectus or any post-effective
            amendment thereto contains any untrue statement of a material fact
            or omits to state 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 (except no
            opinions need be expressed as to the financial statements and notes
            thereto and other financial or statistical data included therein and
            information supplied by you as set forth in Section 1(b) hereof).

                  (xvi) To such counsel's knowledge, all statutes or regulations
            or legal or governmental proceedings required to be described in the
            Registration Statement or Prospectus are described therein as
            required, and all such descriptions in the Registration Statement or
            Prospectus are accurate in all material respects and present fairly
            the information purported to be shown.

                  (xvii) To such counsel's knowledge, none of the Companies has
            any outstanding options, warrants or other rights to purchase or
            acquire any shares of capital stock of any of them except set forth
            in the Registration Statement or the Prospectus.

                  (xviii) The Common Stock conforms as to legal matters in all
            material respects with the statements concerning such shares made in
            the Registration Statement and the Prospectus under the section
            entitled "Description of Capital Stock", and such statements present
            fairly the matters respecting such shares required to be set forth
            in the Registration Statement or the Prospectus.

                  (xix) The Warrants conform as to legal matters in all material
            respects with the statements concerning such Warrants made in the
            Registration Statement and the Prospectus under the section entitled
            "Description of Common Stock Purchase Warrants", and such statements
            present fairly the matters respecting such Warrants required to be
            set forth in the Registration Statement or the Prospectus.

                  (xx) Except as set forth in the Registration Statement and
            Prospectus, to such counsel's knowledge, there is no pending or
            threatened action, suit or proceeding before any court or before or
            by any governmental agency or body to which any of the Companies is
            a party, or of which any of their respective properties or assets
            are the subject, which is required to be disclosed in the
            Registration Statement or Prospectus.

                  (xxi) The contracts filed as Exhibit Nos. 10.1, 10.2, 10.3,
            10.4, 10.10, 10.11, 10.12 and 10.33 to the Registration Statement
            have been duly authorized, executed and delivered by the Company,
            and such counsel has not been advised of any assertion that such
            contracts do not constitute the valid and binding obligation of the
            other parties thereto. The Forms of Contracts filed as Exhibit Nos.
            10.6, 10.7, 10.13, 10.14, 10.31 and 10.34 to the Registration
            Statement have been duly authorized by the Company.

                  (xxii) Such other legal matters relating to this Agreement,
            the Companies and the Securities as you and such counsel shall
            reasonably agree upon.


            In rendering such opinion, such counsel may rely (a) as to matters
      involving the application of laws other than the laws of the United States
      and jurisdictions in which they are admitted, to the extent such counsel
      deems proper and to the extent specified in such opinion, if at all, upon
      an opinion or opinions (in form and substance reasonably satisfactory to
      counsel for Underwriters) of other counsel reasonably acceptable to
      counsel for the Underwriters, familiar with the applicable laws; and (b)
      as to matters of fact, to the extent they deem proper, on certificates of
      responsible officers of the Company and certificates or other written
      statements of officers of departments of various jurisdictions having
      custody of documents respecting the corporate existence or good standing
      of the Companies, provided that copies of any such statements or
      certificates shall be delivered to counsel for the Underwriters, and on
      the representations and warranties of the Company contained in this
      Agreement. The opinion of such counsel for the Company shall state, in
      their opinion, you and they are justified in relying on the opinion of
      such other counsel.

            (h) At the Closing Date, there shall have been delivered to you a
      signed opinion of _____________, addressed to the Underwriters, dated as
      of the Closing Date, in form and substance reasonably satisfactory to
      Rosenman & Colin LLP, counsel for the Underwriters, together with a signed
      or photostatic copy of that opinion for each of the other Underwriters,
      substantially to the effect that:

                  (1) BRL has been duly incorporated and is validly existing and
            in good standing under the laws of the jurisdiction of its
            incorporation and has the corporate power and authority to own and
            lease its properties and to conduct its business as described in the
            Registration Statement and Prospectus;

                  (2) all of the outstanding shares of capital stock of BRL have
            been duly authorized and validly issued, are fully paid and

            clear of any liens, encumbrances, security interests or other
            restrictions;

            Securities to be sold by it under this Agreement, the execution and
            delivery of this Agreement, the undertakings contained in the
            Registration Statement or the Prospectus, the consummation of the
            transactions contemplated in this Agreement nor compliance with the
            terms of this Agreement will conflict with or result in a breach of
            any of the terms or provisions of BRL's charter or by-laws, or any
            material indenture, mortgage, deed of trust, note, bank loan or
            credit agreement or any other agreement or instrument known to such
            counsel and to which BRL is a party or by which BRL is bound or
            affected, any applicable law, rule or regulation or (without search
            of any court dockets) any judgment, order or decree of any
            government, governmental agency or instrumentality or court having
            jurisdiction over BRL or any of its property; and

                  (4) The contract filed as Exhibit No. 10.10 to the
            Registration Statement has been duly authorized, executed and
            delivered by BRL and such counsel has not been advised of any
            assertion that such contract does not constitute the valid and
            binding obligation of the other parties thereto.

            (i) At the Closing Date, you shall have received a Certificate
      signed by the President and the Vice President-Finance of the Company,

                   Each officer signing the Certificate has carefully examined
            the Registration Statement and the Prospectus, and, in his opinion,
            as of the date of the Prospectus, and as of the date of the
            Certificate, neither the Registration Statement nor the Prospectus,
            nor any amendment or supplement, includes an untrue statement of a
            material fact or omits to state a material fact required to be
            stated therein or necessary in order to make the statements therein
            not misleading, and, since the date of the Prospectus, no event has
            occurred which should have been set forth in an amendment or a
            supplement to the Registration Statement or Prospectus which has not
            been so set forth, and, since the respective dates as of which
            information is given in the Registration Statement and the
            Prospectus, there has not been any material adverse change in the
            condition of any of the Companies, financial or otherwise, or, as
            compared with the comparable period in the prior fiscal year, in the
            earnings of any of the Companies from that set forth in the
            Registration Statement, whether or not arising in the ordinary
            course of business.

            (j) At the Closing Date, you shall have received a Certificate
      signed by the President of the Company, dated as of the Closing Date, to
      the effect that:

                  No stop order or similar order with regard to the Registration
            Statement or Prospectus has been issued and no proceedings for that
            purpose have been taken or are, to the knowledge of such officer,
            contemplated by the Commission.

      The Company has complied in all material respects with its obligations
under this Agreement, and the representations and warranties set forth in

      than three business days prior to the Closing Date they have no reason to
      believe that there has been any change in the matters described in the
      prior letters.

            (l) At the Closing Date there shall have been delivered to you, with
      a photostatic copy for each of the several Underwriters, a signed opinion

      Registration Statement, Prospectus and related matters as the
      Representative may request, and the Company shall have furnished to such
      counsel all documents such counsel may have reasonably requested for the
      purpose of enabling them to pass upon those matters. In rendering such
      opinion, Rosenman & Colin LLP may rely, as to incorporation of the Company

      12. CONDITIONS OF OBLIGATIONS OF COMPANY. The obligations of the Company
to sell and deliver the Firm Securities to the several Underwriters are subject
to the condition that the Registration Statement shall become effective with the
Commission not later than 10:00 A.M., New York City time, on the day following
the date of this Agreement, or such later date as shall have been consented to
by the Underwriters (including you) who are obligated to purchase a majority of
the Firm Securities to be purchased by all of the Underwriters pursuant to this
Agreement, and that prior to the Closing Date (and, with respect to the
Additional Securities, prior the Option Closing Date), no stop order or similar
order with regard to the Registration Statement shall have been issued and no
proceedings for that purpose shall have been instituted or shall be pending, or,
to your knowledge or to the knowledge of the Company, shall be contemplated by
the Commission or any other regulatory agency having jurisdiction with respect
to the offer and sales of the Offered Securities.

      13.   SUBSTITUTION OF UNDERWRITERS.

      (a) If one or more Underwriters default in its or their obligations to
purchase and pay for Firm Securities under this Agreement and if the aggregate
amount of the Firm Securities which all Underwriters so defaulting shall have
agreed to purchase does not exceed 10% of the Firm Securities, each
nondefaulting Underwriter shall have the right and is obligated, severally, to
purchase and pay for (in addition to the number of Firm Securities set forth
opposite its name in Schedule I) the number of Remaining Firm Securities
multiplied by a fraction, the numerator of which is the total number of Firm
Securities purchased by such Underwriter and the denominator of which is the
total number of Firm Securities purchased by all non-defaulting Underwriters. In
that event, the Representative, for the accounts of the several nondefaulting
Underwriters, may take up and pay for all or any part of the Remaining Firm
Securities to be purchased by each nondefaulting Underwriter under this
Subsection (a), and may postpone the Closing Date to a time not exceeding three
full business days after the Closing Date determined as provided in Section 3 of
this Agreement; or

      (b) If one or more Underwriters default in its or their obligations to
purchase and pay for Firm Securities under this Agreement and if the aggregate
amount of the Remaining Firm Securities exceeds 10% of the Firm Securities, or
if one or more Underwriters for any reason permitted under this Agreement cancel
its or their obligations to purchase and pay for Firm Securities under this
Agreement, the noncancelling and nondefaulting Underwriters (hereinafter called
the "Remaining Underwriters") shall have the right to purchase such Firm
Securities on the Closing Date in the proportion as may be agreed among them. If
the Remaining Underwriters do not purchase and pay for all such Firm Securities
at the Closing Date, the Closing Date shall be postponed by two business days
and the Remaining Underwriters shall have the right to purchase the Firm
Securities, or to substitute another person or persons to purchase them, or
both, at the postponed Closing Date. If purchasers are not found for such Firm
Securities by the postponed Closing Date, the Closing Date shall be postponed
for a further five business days and the Company shall have the right to
substitute another person or persons, satisfactory to the Representative, to
purchase those Firm Securities at the second postponed Closing Date. If the
Company does not find the purchasers for those Firm Securities by the second
postponed Closing Date, then this


                                      30
<PAGE>   31
Agreement shall automatically terminate and neither the Company nor the
Remaining Underwriters shall be under any obligation under this Agreement
(except that the Company shall remain liable to the extent provided in Sections 
7 and 9(a) and the Underwriters shall remain liable to the extent provided in
Section 9(b)). As used in this Agreement, the term "Underwriter" includes any
person substituted for an Underwriter under this Section 13. Nothing in this
Section will relieve a defaulting Underwriter from liability for its default or
obligate any Underwriter to purchase or find purchasers for any Firm Securities
in excess of those agreed to be purchased by the Underwriter in Sections 2 and
13(a) of this Agreement. If the Representative is the defaulting Underwriter,
the right of first refusal set forth in Section 16 hereof shall terminate.

      14. EFFECTIVE DATE OF AGREEMENT. This Agreement shall become effective at
whichever of the following times shall first occur: (i) at 10:00 A.M., New York
City time, on the next full business day following the date on which the
Registration Statement becomes effective or (ii) at such time after the
Registration Statement has become effective and the Underwriters shall release
the Firm Securities for sale to the public; provided, however, that the
provisions of Sections 7, 9, 10, 14 and 19 hereof shall at all times be
effective. For purposes of this Section 14, the Firm Securities shall be deemed
to have been so released upon the release by the Underwriters for publication,
at any time after the Registration Statement has become effective, of any
newspaper advertisement relating to the Firm Securities or upon the release by
the Underwriters of telegrams offering the Firm Securities for sale to
securities dealers, whichever may occur first.

      15.   TERMINATION OF AGREEMENT.

      (a) This Agreement may be terminated at any time prior to the Closing Date
by you by giving written notice to the Company upon the occurrence of any of the
following events:

            (i) any of the Companies shall have sustained a loss, by reason of
      fire, flood, accident or other calamity, which in your reasonable
      judgment, materially affects the aggregate value of the property owned or
      leased by the Companies taken as a whole or which materially interferes
      with the operation of the business of the Companies taken as a whole,
      regardless of whether or not that loss shall have been insured;

            (ii) any of the Companies has encountered or been threatened with a
      strike (including but not limited to strikes of stevedores and other
      transporters of goods) or other labor dispute or been subjected to
      governmental action or fluctuations in currency or major political
      upheaval which materially affects the aggregate value of the property
      owned or leased or which materially interferes with the operation of its
      business taken as a whole or which in your reasonable judgment makes it
      impracticable or inadvisable to offer for sale or to enforce contracts
      made by the Underwriters for the resale of the Firm Securities;

            (iii) except as set forth in the Prospectus, there shall be pending
      or threatened against any of the Companies or notification has been
      received by any of the Companies of the threat of any material legal or
      governmental proceeding or


                                      31
<PAGE>   32
      action relating generally to the business or prospects of any of the
      Companies which could materially adversely affect any of the Companies
      taken as a whole (including action with respect to credit or interest
      rates) or which in your reasonable opinion makes it impracticable or
      inadvisable to proceed with the offering;

            (iv) any of the certificates, opinions or other documents to be
      delivered on the date of this Agreement or at the Closing Date are not in
      form reasonably satisfactory to counsel to the Underwriters;

            (v) any conditions set forth in Section 11 of this Agreement shall
      not have been satisfied;

            (vi) the Company is merged or consolidated or all or substantially
      all of the capital stock or assets of the Company are acquired by another
      company or group, or there exists a binding legal commitment for the
      foregoing or any other material change of ownership or control occurs;

            (vii) if there has occurred any outbreak of hostilities or
      escalation of any existing hostilities or other calamity or crisis, the
      effect of which on the financial markets of the United States is such as
      to make it impracticable, in the Representative's reasonable judgment, to
      market any of the Firm Securities or the Additional Securities or to
      enforce contracts for the sale of any of the Firm Securities or the
      Additional Securities;

            (viii) a banking moratorium shall have been declared by either
      federal or state authorities;

            (ix) if trading generally on the American Stock Exchange, the New
      York Stock Exchange or NASDAQ has been suspended, or minimum or maximum
      prices for trading have been fixed, or maximum ranges for prices for
      securities have been required, by either of said Exchanges or the NASD or
      by order of the Commission or any other governmental authority;

            (x) there shall have been a change in the general market, political
      or economic conditions in the United States, such that in any such case,
      in the Representative's reasonable judgment, it would be inadvisable to
      proceed with the offering of the Firm Securities; or

            (xi) any law shall be enacted or any regulation promulgated relating
      to the business of any of the Companies which could materially adversely
      affect any of the Companies.

      (b) This Agreement may be terminated by the Company by giving written
notice to you (i) at any time before this Agreement becomes effective in
accordance with Section 14 hereof, or (ii) prior to the Closing Date if the
conditions set forth in Section 12 shall not have been satisfied at or prior to
such date.


                                      32
<PAGE>   33
      (c) If this Agreement shall be terminated by the Company pursuant to
preceding clause (b)(i) because (x) the Company has made, or proposes to make, a
private placement which will provide it with substantial alternative funding
through another investment banking agent, the Representative shall be entitled
to a cash fee equal to 2% of the gross amount of such funding, whether
effectuated by the Company before or after such termination of this Agreement or
(y) because the Company is to be sold, whether by merger, sale of stock, sale of
assets or otherwise, the Representative shall be paid a cash fee of $200,000
should the acquisition or merger close; provided, however, that if in such event
the Company shall choose the Representative as its investment banker in
connection therewith, such $200,000 shall be a credit against any services
rendered by the Representative in such transaction.

      (d) If this Agreement shall be terminated pursuant to this Section 15
other than by reason of the fault of the Representative, the Company, in
addition to the advance provided for in Section 7 hereof, shall pay to you your
accountable expenses, including the reasonable fees and out-of-pocket expenses
of your counsel, in an amount not to exceed $30,000.

      16. RIGHT OF FIRST REFUSAL. Until January 1, 1998, the Company shall
notify you in writing at least thirty (30) days before a proposed public
offering by the Company of any of its securities (other than bank debt or
similar financing, securities offered solely to Company employees, consultants
or representatives, shares issuable pursuant to any dividend reinvestment plan
or securities issuable in transactions enumerated in Rule 145(a) under the
Securities Act) so that you, or, at your option, together with a group of
investment bankers associated with you, shall have the right of first refusal to
effect the public offering on terms at least as favorable to the Company as
those set forth in such notice (which notice will specify the price to the
underwriter or other method of determining the underwriting discount or fee).
You will notify the Company if you intend to exercise your right of first
refusal within thirty (30) days of receipt by you of such notice from the
Company. If you fail to exercise the right of first refusal within the thirty
(30) day period and the terms of the proposed subsequent financing thereafter
are altered in any material respect less favorable to the Company, the Company
shall again offer to you the right of first refusal to effect a subsequent
financing upon such terms and you shall have ten (10) days from the date of
receipt of such notice to notify the Company of your acceptance.

      17. NOTICES. All communications under this Agreement shall be in writing

in accordance with this Agreement.

            (c) From time to time, up to the Warrant Expiration Date, the
Warrant Agent shall execute and deliver Warrant Certificates in required whole
number denominations to the persons entitled thereto in connection with any
transfer or exchange permitted under this Agreement; provided that no Warrant
Certificates shall be issued except (i) those initially issued hereunder; (ii)
those issued upon the exercise of fewer than all Warrants represented by any
Warrant Certificate, to evidence any unexercised Warrants held by the exercising
Registered Holder; (iii) those issued upon any transfer or exchange pursuant to
Section 6 herein; (iv) those issued in replacement of lost, stolen, destroyed or
mutilated Warrant Certificates pursuant to Section 7; and (v) at the option of
the Company, in such form as may be approved by its Board of Directors, to
reflect (a) any adjustment or change in the Exercise Price or the number of
shares of Common Stock purchasable upon exercise of the Warrants made pursuant
to Section 8 hereof and (b) other modifications approved by Registered Holders
in accordance with Section 16 hereof.

            SECTION 3.  Form and Execution of Warrant Certificates.

            (a) The Warrant Certificates shall be substantially in the form
annexed hereto as Exhibit A (the provisions of which are hereby incorporated
herein) and may have such letters, numbers or other marks of identification or
designation and such legends, summaries or endorsements printed, lithographed,
engraved or typed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Agreement, or as may be required to
comply with any law or with any rule or regulation made pursuant thereto or with
any rule or regulation of any stock exchange or securities association on which
or through which the Warrants may be listed, or to conform to usage. The Warrant
Certificates shall be dated the date of issuance thereof (whether upon initial
issuance, transfer, exchange or in lieu of mutilated, lost, stolen, or destroyed
Warrant Certificates) and issued in registered form. Warrants shall be numbered
serially with the letter W.

            (b) Warrant Certificates shall be executed on behalf of the Company
by its Chairman of the Board, President or any Vice President and by its
Secretary or an Assistant Secretary, by manual signatures or by facsimile
signatures printed thereon, shall have imprinted thereon a facsimile of the
Company's seal and shall be countersigned by an authorized signatory of the
Warrant Agent. In case any officer of the Company who shall


                                      3
<PAGE>   4
have signed any of the Warrant Certificates shall cease to be such officer of
the Company before the date of issuance of the Warrant Certificates and issue
and delivery thereof, such Warrant Certificates may nevertheless be issued and
delivered with the same force and effect as though the person who signed such
Warrant Certificates had not ceased to be such officer of the Company. After
execution by the Company Warrant Certificates shall be delivered by the Warrant
Agent to the Registered Holder.

            SECTION 4.  Exercise.

            Each Warrant may be exercised by the Registered Holder thereof at
any time after the effective date of the Registration Statement and until the
Warrant Expiration Date, upon the terms and subject to the conditions set forth
herein and in the applicable Warrant Certificate. A Warrant shall be deemed to
have been exercised immediately prior to the close of business on the Exercise
Date and the person entitled to receive the securities deliverable upon such
exercise shall be treated for all purposes as the holder of such securities upon
exercise of the Warrant Certificate as of the close of business on the Exercise
Date. As soon as practicable on or after the Exercise Date, the Warrant Agent
shall deposit the proceeds received from the exercise of a Warrant, and promptly
after clearance of checks received in payment of the Exercise Price pursuant to
such Warrants, cause to be issued and delivered by the Transfer Agent, to the
person or persons entitled to receive the same, a certificate or certificates
for the securities deliverable upon such exercise (plus a certificate for any
remaining unexercised Warrants of the Registered Holder, if applicable).
Notwithstanding the foregoing, in the case of payment made in the form of a
check drawn on an account of Janney Montgomery Scott Inc. (the "Representative")
or such other investment banks and brokerage houses as the Company shall
approve, certificates shall immediately be issued without any delay. Upon the
exercise of any Warrant and clearance of the funds received, the Warrant Agent
shall promptly remit the payment received for the Warrant to the Company or as
the Company may direct in writing.

            SECTION 5.  Reservation of Shares; Listing; Payment of Taxes; etc.

            (a) The Company covenants that it will at all times reserve and keep
available out of its authorized Common Stock, solely for the purpose of issuance
upon exercise of Warrants, such number of shares of Common Stock as shall then
be issuable upon the exercise of all outstanding Warrants. The Company covenants
that all shares of Common Stock which shall be issuable upon exercise of the
Warrants and payment of the Exercise Price in compliance with this Warrant
Agreement and the Warrant Certificate shall, at the time of delivery, be duly
and validly issued, fully paid, nonassessable and free from all taxes, liens and
charges with respect to the issue thereof (other than those which the Company
shall promptly pay or discharge).

            (b) The Company will use reasonable efforts to obtain appropriate
approvals or registrations under state "blue sky" securities laws with respect
to the exercise of the Warrants; provided, however, that the Company shall not
be obligated to file any general consent to service of process or qualify as a
foreign corporation in any jurisdiction. With


                                        4
<PAGE>   5
respect to any such securities laws, however, Warrants may not be exercised by,
or shares of Common Stock issued to, any Registered Holder in any state in which
such exercise would be unlawful.

            (c) The Company shall pay all documentary, stamp or similar taxes
and other governmental charges that may be imposed with respect to the issuance
of Warrants, or the issuance, or delivery of any shares upon exercise of the
Warrants; provided, however, that if shares of Common Stock are to be delivered
in a name other than the name of the Registered Holder of the Warrant
Certificate representing any Warrant being exercised, then no such delivery
shall be made unless the person requesting the same has paid to the Warrant
Agent the amount of transfer taxes or charges incident thereto, if any.

            (d) The Warrant Agent is hereby irrevocably authorized to
requisition the Transfer Agent from time to time for certificates representing
shares of Common Stock required upon exercise of the Warrants, and the Company
will authorize the Transfer Agent to comply with all such proper requisitions.

            SECTION 6.  Exchange and Recordation of Transfer.

            Subject to the restrictions on transfer contained in the Warrant
Certificates:

            (a) Warrant Certificates may be exchanged for other Warrant
Certificates representing an equal aggregate number of Warrants or may be
transferred in whole or in part. Warrant Certificates to be exchanged shall be
surrendered to the Warrant Agent at its Corporate Office, and upon satisfaction
of the terms and provisions hereof, the Company shall execute, and the Warrant
Agent shall countersign, issue and deliver in exchange therefor the Warrant
Certificate or Certificates which the Registered Holder making the exchange
shall be entitled to receive.

            (b) The Warrant Agent shall keep books at its office, in which it
shall register Warrant Certificates and the transfer thereof in accordance with
its regular practice. Upon due presentment for recordation of transfer of any
Warrant Certificate at its office, the Company shall execute and the Warrant
Agent shall issue and deliver to the transferee or transferees a new Warrant
Certificate or Certificates representing an equal aggregate number of Warrants.

            (c) With respect to all Warrant Certificates presented for
recordation of transfer, or for exchange or exercise, the exercise form on the
reverse thereof shall be duly endorsed, or be accompanied by a written
instrument or instruments of transfer and exercise, in form satisfactory to the
Company, duly executed by the Registered Holder or his attorney-in-fact duly
authorized in writing.

            (d) A service charge may be imposed by the Warrant Agent upon the
Company for any exchange or recordation of transfer of Warrant Certificates. The
Company


                                      5
<PAGE>   6
may require payment by a Registered Holder of a sum sufficient to cover any tax
or other governmental charge that may be imposed in connection therewith.

            (e) Prior to due presentment for recordation of transfer thereof,
the Company and the Warrant Agent may deem and treat the Registered Holder of
any Warrant Certificate as the absolute owner thereof and of each Warrant
represented thereby (notwithstanding any notations of ownership or writing
thereon made by anyone other than a duly authorized officer of the Company or
the Warrant Agent) for all purposes and shall not be affected by any notice to
the contrary. The Warrants, which the Company intends to publicly offer with the
Common Stock, will be separately transferable immediately following the
completion of the Public Offering.

            SECTION 7. Loss or Mutilation. Upon receipt by the Company and the
Warrant Agent of evidence satisfactory to them of the ownership and loss, theft,
destruction or mutilation of any Warrant Certificate and (in case of loss, theft
or destruction) of indemnity satisfactory to them, and (in the case of
mutilation) upon surrender and cancellation thereof, the Company shall execute
and the Warrant Agent shall (in the absence of notice to the Company and/or
Warrant Agent that the Warrant Certificate has been acquired by a bona fide
purchaser) countersign and deliver to the Registered Holder in lieu thereof a
new Warrant Certificate of like tenor representing an equal aggregate number of
Warrants. Registered Holders requesting a substitute Warrant Certificate will be
required to comply with such other reasonable regulations and pay such other
reasonable charges as the Warrant Agent may prescribe.

            SECTION 8. Adjustment of Exercise Price and Number of Shares of
                       Common Stock or Warrants.

            (a) Subject to the exceptions referred to in Section 8(g) below, in
the event the Company shall, at any time or from time to time after the date
hereof, sell any shares of Common Stock for a consideration per share less than
the current fair market value per share of the Common Stock on the date of the
sale or issue any shares of Common Stock as a stock dividend to the holders of
Common Stock, or subdivide or combine the outstanding shares of Common Stock
into a greater or lesser number of shares (any such sale, issuance, subdivision
or combination being herein called a "Change of Shares"), then, and thereafter
upon each Change of Shares, the Exercise Price in effect immediately prior to
such Change of Shares shall be changed to a price (including any applicable
fraction of a cent) determined by multiplying the Exercise Price in effect
immediately prior thereto by a fraction, the numerator of which shall be the sum
of the number of shares of Common Stock outstanding immediately prior to the
issuance of such additional shares plus the number of shares of Common Stock
which the aggregate consideration received (determined as provided in subsection
8(f)(F) below), if any, for the issuance of such additional shares would
purchase at such current market price per share of Common Stock, and the
denominator of which shall be the sum of the number of shares of Common Stock
outstanding immediately after the issuance of such additional shares. Such
adjustment shall be made successively whenever such an issuance is made.


                                        6
<PAGE>   7
                  Upon each adjustment of the Exercise Price pursuant to this
Section 8, the total number of shares of Common Stock purchasable upon the
exercise of each Warrant shall (subject to the provisions contained in Section 
8(b) hereof) be such number of shares (calculated to the nearest tenth)
purchasable at the Exercise Price immediately prior to such adjustment
multiplied by a fraction, the numerator of which shall be the Exercise Price in
effect immediately prior to such adjustment and the denominator of which shall
be the Exercise Price in effect immediately after such adjustment.

            (b) The Company may elect, upon any adjustment of the Exercise Price
hereunder, to adjust the number of Warrants outstanding, in lieu of the
adjustment in the number of shares of Common Stock purchasable upon the exercise
of each Warrant as hereinabove provided, so that each Warrant outstanding after
such adjustment shall represent the right to purchase one quarter of a share of
Common Stock. Each Warrant held of record prior to such adjustment of the number
of Warrants shall become that number of Warrants (calculated to the nearest
tenth) determined by multiplying the number one by a fraction, the numerator of
which shall be the Exercise Price in effect immediately prior to such adjustment
and the denominator of which shall be the Exercise Price in effect immediately
after such adjustment. Upon each adjustment of the number of Warrants pursuant
to this Section 8, the Company shall, as promptly as practicable, cause to be
distributed to each Registered Holder of Warrant Certificates, on the date of
such adjustment, Warrant Certificates evidencing, subject to Section 10 hereof,
the number of additional Warrants to which such Holder shall be entitled as a
result of such adjustment or, at the option of the Company, cause to be
distributed to such Holder in substitution and replacement for the Warrant
Certificates held by him prior to the date of adjustment (and upon surrender
thereof, if required by the Company) new Warrant Certificates evidencing the
number of Warrants to which such Holder shall be entitled after such adjustment.

            (c) In case of any reclassification, capital reorganization or other
similar change of outstanding shares of Common Stock, or in case of any
consolidation or merger of the Company with or into another corporation (other
than a consolidation or merger in which the Company is the continuing
corporation and which does not result in any reclassification, capital
reorganization or other change of outstanding shares of Common Stock), or in
case of any sale or conveyance to another corporation of the property of the
Company as, or substantially as, an entirety (other than a sale/leaseback,
mortgage or other financing transaction), the Company shall cause effective
provision to be made so that each holder of a Warrant then outstanding shall
have the right thereafter, by exercising such Warrant, to purchase the kind and
number of shares of stock or other securities or property (including cash)
receivable upon such reclassification, capital reorganization or other change,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Common Stock that might have been purchased upon exercise of such Warrant
immediately prior to such reclassification, capital reorganization or other
similar change, consolidation, merger, sale or conveyance. Any such provision
shall include provision for adjustments that shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Section 8. The
foregoing provisions shall similarly apply to successive reclassifications,
capital


                                      7
<PAGE>   8
reorganizations and other changes of outstanding shares of Common Stock and to
successive consolidations, mergers, sales or conveyances.

            (d) Irrespective of any adjustments or changes in the Exercise Price
or the number of shares of Common Stock purchasable upon exercise of the
Warrants, the Warrant Certificates theretofore issued, unless the Company shall
exercise its option to issue new Warrant Certificates pursuant to Section 2(c)
hereof, need not be amended or replaced, but certificates thereafter issued
shall bear an appropriate legend or other notice of any adjustments.

            (e) After each adjustment of the Exercise Price pursuant to this
Section 8, the Company will promptly prepare a certificate signed by the
Chairman or President, and by the Treasurer or an Assistant Treasurer or the
Secretary or an Assistant Secretary, of the Company setting forth: (i) the
Exercise Price as so adjusted, (ii) the number of shares of Common Stock
purchasable upon exercise of each Warrant after such adjustment, and, if the
Company shall have elected to adjust the number of Warrants, the number of
Warrants to which the Registered Holder of each Warrant shall then be entitled,
and the adjustment in Redemption Price resulting therefrom, and (iii) a brief
statement of the facts accounting for such adjustment. The Company will promptly
file such certificate with the Warrant Agent and cause a brief summary thereof
to be sent by ordinary first class mail to the Representative and to each
Registered Holder at his last address as it shall appear on the registry books
of the Warrant Agent. The affidavit of an officer of the Warrant Agent or the
Secretary or an Assistant Secretary of the Company that such notice has been
mailed shall, in the absence of fraud, be prima facie evidence of the facts
stated therein.

            (f) For purposes of Section 8(a) and 8(b) hereof, the following
provisions (A) to (F) shall also be applicable:

                  (A) The number of shares of Common Stock outstanding at any
            given time shall include shares of Common Stock owned or held by or
            for the account of the Company and the sale or issuance of such
            treasury shares or the distribution of any such treasury shares
            shall not be considered a Change of Shares for purposes of said
            sections.

                  (B) No adjustment of the Exercise Price shall be made unless
            such adjustment would require an increase or decrease of at least
            $.02 in such price; provided that any adjustments which by reason of
            this clause (B) are not required to be made shall be carried forward
            and shall be made at the time of and together with the next
            subsequent adjustment which, together with any adjustment(s) so
            carried forward, shall require an increase or decrease of at least
            $.02 in the Exercise Price then in effect hereunder.

                  (C) In case of (1) the sale by the Company for cash of any
            rights or warrants to subscribe for or purchase, or any options for
            the purchase of, Common Stock or any securities convertible into or
            exchangeable for Common
                                        8
<PAGE>   9
            Stock without the payment of any further consideration other than
            cash, if any (such convertible or exchangeable securities being
            herein called "Convertible Securities"), or (2) the issuance by the
            Company, without the receipt by the Company of any consideration
            therefor, of any rights or warrants to subscribe for or purchase, or
            any options for the purchase of, Common Stock or Convertible
            Securities, in each case, if (and only if) the consideration payable
            to the Company upon the exercise of such rights, warrants or options
            shall consist of cash, whether or not such rights, warrants or
            options, or the right to convert or exchange such Convertible
            Securities, are immediately exercisable, and the price per share for
            which Common Stock is issuable upon the exercise of such rights,
            warrants or options or upon the conversion or exchange of such
            Convertible Securities (determined by dividing (x) the minimum
            aggregate consideration payable to the Company upon the exercise of
            such rights, warrants or options, plus the consideration received by
            the Company for the issuance or sale of such rights, warrants or
            options, plus, in the case of such Convertible Securities, the
            minimum aggregate amount of additional consideration, if any, other
            than such Convertible Securities, payable upon the conversion or
            exchange thereof, by (y) the total maximum number of shares of
            Common Stock issuable upon the exercise of such rights, warrants or
            options or upon the conversion or exchange of such Convertible
            Securities issuable upon the exercise of such rights, warrants or
            options) is less than the market price of the Common Stock on the
            date of the issuance or sale of such rights, warrants or options,
            then the total maximum number of shares of Common Stock issuable
            upon the exercise of such rights, warrants or options or upon the
            conversion or exchange of such Convertible Securities (as of the
            date of the issuance or sale of such rights, warrants or options)
            shall be deemed to be outstanding shares of Common Stock for
            purposes of Sections 8(a) and 8(b) hereof and shall be deemed to
            have been sold for cash in an amount equal to such price per share.

                  (D) In case of the sale by the Company for cash of any
            Convertible Securities, whether or not the right of conversion or
            exchange thereunder is immediately exercisable, and the price per
            share for which Common Stock is issuable upon the conversion or
            exchange of such Convertible Securities (determined by dividing (x)
            the total amount of consideration received by the Company for the
            sale of such Convertible Securities, plus the minimum aggregate
            amount of additional consideration, if any, other than such
            Convertible Securities, payable upon the conversion or exchange
            thereof, by (y) the total maximum number of shares of Common Stock
            issuable upon the conversion or exchange of such convertible
            Securities) is less than the market price of the Common Stock on the
            date of the sale of such Convertible Securities, then the total
            maximum number of shares of Common Stock issuable upon the
            conversion or exchange of such Convertible Securities (as of the
            date of the sale of such Convertible Securities) shall be deemed to
            be outstanding shares of Common Stock for purposes of Sections 8(a)
            and 8(b)


                                        9
<PAGE>   10
            hereof and shall be deemed to have been sold for cash in an amount
            equal to such price per share.

                  (E) If the exercise or purchase price provided for in any
            right, warrant or option referred to in (C) above, or the rate at
            which any Convertible Securities referred to in (C) or (D) above are
            convertible into or exchangeable for Common Stock, shall change at
            any time (other than under or by reason of provisions designed to
            protect against dilution), the Exercise Price then in effect
            hereunder shall forthwith be readjusted to such Exercise Price as
            would have been obtained (1) had the adjustments made upon the
            issuance or sale of such rights, warrants, options or Convertible
            Securities been made upon the basis of the issuance of only the
            number of shares of Common Stock theretofore actually delivered (and
            the total consideration received therefor) upon the exercise of such
            rights, warrants or options or upon the conversion or exchange of
            such Convertible Securities, (2) had adjustments been made on the
            basis of the Exercise Price as adjusted under clause (1) for all
            transactions (which would have affected such adjusted Exercise
            Price) made after the issuance or sale of such rights, warrants,
            options or Convertible Securities, and (3) had any such rights,
            warrants, options or Convertible Securities then still outstanding
            been originally issued or sold at the time of such change. On the
            expiration of any such right, warrant or option or the termination
            of any such right to convert or exchange any such Convertible
            Securities, the Exercise Price then in effect hereunder shall
            forthwith be readjusted to such Exercise Price as would have been
            obtained (a) had the adjustments made upon the issuance or sale of
            such rights, warrants, options or Convertible Securities been made
            upon the basis of the issuance of only the number of shares of
            Common Stock theretofore actually delivered (and the total
            consideration received therefor) upon the exercise of such rights,
            warrants or options or upon the conversion or exchange of such
            Convertible Securities and (b) had adjustments been made on the
            basis of the Exercise Price as adjusted under clause (a) for all
            transactions (which would have affected such adjusted Exercise
            Price) made after the issuance or sale of such rights, warrants,
            options or Convertible Securities.

                  (F) In case of the sale for cash of any shares of Common
            Stock, any Convertible Securities, any rights or warrants to
            subscribe for or purchase, or any options for the purchase of,
            Common Stock or Convertible Securities, the consideration received
            by the Company therefore shall be deemed to be the gross sales price
            therefor without deducting therefrom any expense paid or incurred by
            the Company or any underwriting discounts or commissions or
            concessions paid or allowed by the Company in connection therewith.

            (g) No adjustment to the Exercise Price of the Warrants or to the
number of shares of Common Stock purchasable upon the exercise of each Warrant
will be made, however,


                                       10
<PAGE>   11
                  (i) upon the exercise of any of the options presently
            outstanding under the Company's 1990 Stock Option Plan (the "1990
            Stock Option Plan") for officers, directors and all employees of the
            Company outstanding as of the date hereof; or

                  (ii) upon the issuance of any warrants issued pursuant to the
            Company's 1991 Directors' Warrant Plan (the "1991 Warrant Plan"); or

                  (iii) upon the grant or exercise of any other options or
            warrants which may hereafter be granted or exercised under the 1990
            Stock Option Plan or under the 1991 Directors' Warrant Plan; or

                  (iv) upon the sale or exercise of the Warrants issued to the
            Representative in connection with the Public Offering (the
            "Underwriter's Warrants") or the exercise of the Warrants issuable
            upon exercise of the Underwriter's Warrant; or

                  (v) upon the issuance or sale of Common Stock upon the
            conversion of the Company's Class A Preferred Stock or Class B
            Preferred Stock outstanding as of the date hereof; or

                  (vi) upon the issuance or sale of Common Stock upon conversion
            or exchange of any convertible debentures outstanding as of the date
            hereof; or

                  (vii) upon the issuance or sale of Common Stock upon the
            exercise of warrants outstanding (other than those granted pursuant
            to the 1991 Directors' Warrant Plan) as of the date of the Public

authorized which shall not be limited to a fixed sum or percentage in respect of

Warrants as a result of a subdivision or combination or consisting of a change
in par value, or from par value to no par value, or from no par value to par
value, such shares of Common Stock as so reclassified or changed.

            (i) Any determination as to whether an adjustment in the Exercise

Directors of the Company.

reported by NASDAQ averages in excess of 200% of the Exercise Price of the
Warrants in effect at the time of determination for a period of 30 days ending
within 15 days of the Redemption Notice Date, subject to certain adjustment as
set forth in Section 9(f) below.

            (b) In the event the conditions set forth in Section 9(a) are met,
and the Company shall desire to exercise its right so to redeem the Warrants, it

not later than the thirtieth day before the date fixed for redemption, at his or
her last address as shall appear on the records of the Warrant Agent. Any notice
mailed in the manner provided herein shall be conclusively presumed to have been
duly given whether or not the Registered Holder receives such notice.


                                      12
<PAGE>   13
            (c) The Redemption Notice shall specify (i) the Redemption Price,
(ii) the Redemption Date, (iii) the place where the Warrant Certificates shall
be delivered and the Redemption Price to be paid, and (iv) that the right to
exercise the Warrant shall terminate at 5:00 P.M. (New York time) on the
Redemption Date. An affidavit of the Warrant Agent or of the Secretary or an
Assistant Secretary of the Company that the Redemption Notice has been mailed
shall, in the absence of fraud, be prima facie evidence of the facts stated
therein.

            (d) Provided that the Company has irrevocably provided for the
payment of the Redemption Price, any right to exercise a Warrant shall terminate
at 5:00 P.M. (New York time) on the Redemption Date. After 5:00 P.M. on the
Redemption Date, Registered Holders of the Warrants shall have no further
rights, except to receive upon surrender of the Warrant the Redemption Price.

            (e) From and after 5:00 P.M. (New York time) on the Redemption Date,
the Company shall, at the place specified in the Redemption Notice, upon
presentation and surrender to the Company by or on behalf of the Registered
Holder thereof of one or more Warrants to be redeemed, deliver or cause to be
delivered to or upon the written order of such Registered Holder a sum in cash
equal to the Redemption Price of each such Warrant.

            (f) If the Exercise Price is adjusted pursuant to Section 8 hereof,
the Redemption Price shall be proportionately adjusted by the ratio by which the
total number of shares of Common Stock outstanding immediately prior to such
event bears to the total number of shares of Common Stock to be outstanding
immediately after such event.

            SECTION 10.       Fractional Warrants and Fractional Shares.

            (a) Regardless of whether or not the number of shares of Common
Stock purchasable upon the exercise of each Warrant is adjusted pursuant to
Section 8 hereof, the Company shall nevertheless not be required to issue
fractions of shares upon exercise of the Warrants or otherwise, or to distribute
certificates that evidence fractional shares. With respect to any fraction of a
share called for upon any exercise hereof, the Company shall pay to the
Registered Holder an amount in cash equal to such fraction multiplied by the
current market value of such fractional share, determined as follows:

                  (1) if the Common Stock is listed on a national securities
            exchange or admitted to unlisted trading privileges on such exchange
            or listed for trading on the Nasdaq National Market System ("NMS"),
            the current market value shall be the last reported sale price of
            the Common Stock on such exchange or system on the last business day
            prior to the date of exercise; or

                  (2) if the Common Stock is listed in the over-the-counter
            market (other than on NMS) or admitted to unlisted trading
            privileges thereon, the current market value shall be the mean of
            the last reported bid and asked prices reported by the National
            Quotation Bureau, Inc. on the last business day prior to the date of
            the exercise; or


                                      13
<PAGE>   14
                  (3) if the Common Stock is not so listed or admitted to
            unlisted trading privileges and bid and asked prices are not so
            reported, the current market value shall be an amount determined in
            such reasonable manner as may be prescribed by the Board of
            Directors of the Company.

            SECTION 11. Warrant Holders Not Deemed Stockholders. No Registered
Holder shall, as such, be entitled to vote or to receive dividends or be deemed
the holder of Common Stock that may at any time be issuable upon exercise of
such Warrants for any purpose whatsoever, nor shall anything contained herein be
construed to confer upon the holder of Warrants, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action (whether upon any recapitalization,
issue or reclassification of stock, change of par value or change of stock to no
par value, consolidation, merger or conveyance or otherwise), or to receive
notice of meetings, or to receive dividends or subscription rights, until such
Registered Holder shall have exercised such Warrants and been issued shares of
Common Stock in accordance with the provisions hereof.

            SECTION 12. Rights of Action. All rights of action with respect to
this Agreement are vested in the respective Registered Holders of the Warrants,
and any Registered Holder of a Warrant, without consent of the Warrant Agent or
of the holder of any other Warrant, may, on his own behalf and for his own
benefit, enforce against the Company his right to exercise his Warrants for the
purchase of shares of Common Stock in the manner provided in the Warrant
Certificate and this Agreement.

            SECTION 13. Agreement of Warrant Holders. Every holder of a Warrant,
by his acceptance thereof, consents and agrees with the Company, the Warrant
Agent and every other holder of a Warrant that:

            (a) The Warrants are transferable only on the registry books of the
Warrant Agent by the Registered Holder thereof in person or by his
attorney-in-fact duly authorized in writing and only if the Warrant Certificates
representing such Warrants are surrendered at the office of the Warrant Agent,
duly endorsed or accompanied by a proper instrument of transfer satisfactory to
the Warrant Agent and the Company in their sole discretion, together with
payment of any applicable transfer taxes; and

            (b) The Company may deem and treat the person in whose name the
Warrant Certificate is registered as the Registered Holder thereof and as the
absolute, true and lawful owner of the Warrants represented thereby for all
purposes, and the Company shall not be affected by any notice or knowledge to
the contrary, except as otherwise expressly provided in Section 7 hereof.

            SECTION 14. Cancellation of Warrant Certificates. If the Company
shall purchase or acquire any Warrant or Warrants, whether upon exercise thereof
open market purchase, redemption or otherwise, the Warrant Certificate or
Warrant Certificates


                                      14
<PAGE>   15
evidencing the same shall thereupon be cancelled by the Warrant Agent and
retired. The Warrant Agent shall also cancel Warrant Certificates surrendered to
the Warrant Agent following exercise of any or all of the Warrants represented
thereby or delivered to it for transfer, splitup, combination or exchange.

            SECTION 15. Concerning the Warrant Agent. The Warrant Agent acts
hereunder as agent and in a ministerial capacity for the Company, and its duties
shall be determined solely by the provisions hereof. The Warrant Agent shall
not, by issuing and delivering Warrant Certificates or by any other act
hereunder be deemed to make any representations as to the validity, value or
authorization of the Warrant Certificates or the Warrants represented thereby or
of any securities or other property delivered upon exercise of any Warrant or
whether any stock issued upon exercise of any Warrant is fully paid and
nonassessable.

            The Warrant Agent shall account promptly to the Company with respect
to Warrants exercised and concurrently pay the Company, as provided in Section 
4, all moneys received by the Warrant Agent upon the exercise of such Warrants.
The Warrant Agent shall, upon request of the Company from time to time, deliver
to the Company such complete reports of registered ownership of the Warrants and
such complete records of transactions with respect to the Warrants and the
shares of Common Stock as the Company may request. The Warrant Agent shall also
make available to the Company for inspection by their agents or employees, from
time to time as either of them may request, such original books of accounts and
record as may be maintained by the Warrant Agent in connection with the issuance
and exercise of Warrants hereunder, such inspections to occur at the Warrant
Agent's office as specified in Section 17, during normal business hours.

            The Warrant Agent shall not at any time be under any duty or
responsibility to any Registered Holder to make or cause to be made any
adjustment of the Exercise Price provided in this Agreement, or to determine
whether any fact exists which may require any such adjustments, or with respect
to the nature or extent of any such adjustment, when made, or with respect to
the method employed in making the same. It shall not (i) be liable for any
recital or statement of facts contained herein or for any action taken, suffered
or omitted by it in reliance on any Warrant Certificate or other document or
instrument believed by it in good faith to be genuine and to have been signed or
presented by the proper party or parties, (ii) be responsible for any failure on
the part of the Company to comply with any of its covenants and obligations
contained in this Agreement or in any Warrant Certificate, or (iii) be liable
for any act or omission in connection with this Agreement except for its own
negligence or wilful misconduct.

            The Warrant Agent may at any time consult with counsel satisfactory
to it (who may be counsel for the Company) and shall incur no liability or
responsibility for any action taken, suffered or omitted by it in good faith in
accordance with the opinion or advice of such counsel.


                                      15
<PAGE>   16
            Any notice, statement, instruction, request, direction, order or
demand of the Company shall be sufficiently evidenced by an instrument signed by
the Chairman of the Board, President, any Vice President, its Secretary, or
Assistant Secretary (unless other evidence in respect thereof is herein
specifically prescribed). The Warrant Agent shall not be liable for any action
taken, suffered or omitted by it in accordance with such notice, statement,
instruction, request, direction, order or demand believed by it to be genuine.

            The Company agrees to pay the Warrant Agent reasonable compensation
for its services hereunder and to reimburse it for its reasonable expenses
hereunder; it further agrees to indemnify the Warrant Agent and save it harmless
against any and all losses, expenses and liabilities, including judgments, costs
and counsel fees, for anything done or omitted by the Warrant Agent in the
execution of its duties and powers hereunder except losses, expenses and
liabilities arising as a result of the Warrant Agent's negligence or wilful
misconduct.

            The Warrant Agent may resign its duties and be discharged from all
further duties and liabilities hereunder (except liabilities arising as a result
of the Warrant Agent's own negligence or wilful misconduct), upon 30 days' prior
written notice to the Company and the Company may discharge the Warrant Agent
from its duties and liabilities hereunder upon 30 days' prior written notice to
the Warrant Agent. At least 15 days prior to the date such resignation or
discharge is to become effective, the Warrant Agent shall cause a copy of such
notice of resignation or discharge to be mailed to the Registered Holder of each
Warrant Certificate at the Company's expense. Upon such resignation or
discharge, or any inability of the Warrant Agent to act as such hereunder, the
Company shall appoint a new warrant agent in writing. If the Company shall fail
to make such appointment within a period of 15 days after it has been notified
in writing of such resignation by the resigning Warrant Agent, or within a
period of 15 days after the Warrant Agent has been notified by the Company of
such discharge, then the Registered Holder of any Warrant Certificate may apply
to any court of competent jurisdiction for the appointment of a new warrant
agent. Any new warrant agent, whether appointed by the Company or by such a
court, shall be a bank or trust company having a capital and surplus, as shown
by its last published report to its stockholders, of not less than $10,000,000
or a stock transfer company. After acceptance in writing of such appointment by
the new warrant agent is received by the Company, the Warrant Agent's
resignation or discharge shall be deemed to be effective and such new warrant
agent shall be vested with the same powers, rights, duties and responsibilities
as if it had been originally named herein as the Warrant Agent, without any
further assurance, conveyance, act or deed; but if for any reason it shall be
necessary or expedient to execute and deliver any further assurance, conveyance,
act or deed, the same shall be done at the expense of the Company and shall be
legally and validly executed and delivered by the resigning Warrant Agent. Not
later than the effective date of any such appointment the Company shall file
notice thereof with the resigning Warrant Agent and shall forthwith cause a copy
of such notice to be mailed to the Registered Holder of each Warrant
Certificate.

            Any corporation into which the Warrant Agent or any new warrant
agent may be converted or merged or any corporation resulting from any
consolidation to which the Warrant Agent or any new warrant agent shall be a
party or any corporation succeeding to the


                                      16
<PAGE>   17
trust business of the Warrant Agent shall be a successor warrant agent under
this Agreement without any further act, provided that such corporation is
eligible for appointment as successor to the Warrant Agent under the provisions
of the preceding paragraph. Any such successor warrant agent shall promptly
cause notice of its succession as warrant agent to be mailed to the Company and
to the Registered Holder of each Warrant Certificate.

            The Warrant Agent, its subsidiaries and affiliates, and any of its
or their officers or directors, may buy and hold or sell Warrants or other
securities of the Company and otherwise deal with the Company in the same manner
and to the same extent and with like effects as though it were not Warrant
Agent. Nothing herein shall preclude the Warrant Agent from acting in any other
capacity for the Company or for any other legal entity.

            SECTION 16. Modification of Agreement.

            (a) Subject to the provisions of Section 4(b), the parties hereto
may by supplemental agreement make any changes or corrections in this Agreement
(i) that they shall deem appropriate to cure any ambiguity or to correct any
defective or inconsistent provision or manifest mistake or error herein
contained; (ii) to reflect an increase in the number of Warrants which are to be
governed by this Agreement resulting from an increase in the size of the Public
Offering; or (iii) that they may deem necessary or desirable and which shall not
adversely affect the interests of the holders of Warrant Certificates; provided,
however, that except as otherwise indicated in this Section and this Agreement,
this Agreement shall not otherwise be modified, supplemented or altered in any
respect except with the consent in writing of the Registered Holders of Warrant
Certificates representing not less than two-thirds of the Warrants then
outstanding.

communications hereunder shall be in writing and shall be deemed to have been
made when delivered or mailed first class registered or certified mail, postage
prepaid as follows: if to the Registered Holder of a Warrant Certificate, at the
address of such holder as shown on the registry books maintained by the Warrant
Agent; if to the Company, at 219 South Street, New Providence, New Jersey,
07974, Attention: Richard S. Rosenfeld, Chief Financial Officer; if to the
Warrant Agent, at its Corporate Office.

            SECTION 18. Governing Law. This Agreement shall be governed by and

reference to principles of conflict of laws.

            SECTION 19. Binding Effect. This Agreement shall be binding upon and
inure to the benefit of the Company and the Warrant Agent (and their respective
successors and assigns) and the holders from time to time of Warrant
Certificates. Nothing in


                                      17
<PAGE>   18
this Agreement is intended or shall be construed to confer upon any other person
any right, remedy or claim, in equity or at law, or to impose upon any other
person any duty, liability or obligation.

            SECTION 20. Termination. This Agreement shall terminate on the
earliest to occur of (i) the Expiration Date of all the Warrants, (ii) the date
upon which all Warrants have been exercised and (iii) the date on which the
Company certifies to the Warrant Agent that no Warrants are outstanding;
provided however, that notwithstanding any such termination, the Warrant Agent
shall be obligated to deliver funds to the Company in accordance with this
Agreement.

            SECTION 21. Counterparts. This Agreement may be executed in all
counterparts, all of which taken together shall constitute a single document.

                  THIS CERTIFIES THAT:
or registered assigns is the registered holder (the "Registered Holder") of the
number of Warrants set forth above, each of which represents the right to
purchase one-quarter of a fully paid and nonassessable share of common stock,
par value $.01 per share (the "Common Stock"), of Barringer Technologies Inc., a
Delaware corporation (the "Company"), at any time until the Expiration Date
hereinafter referred to, by surrendering this Warrant Certificate, with the
exercise form set forth hereon duly executed with signatures guaranteed as
provided below, at the office maintained pursuant to the Warrant Agreement
hereinafter referred to for that purpose by American Stock Transfer & Trust

called the "Warrant Agent"), and by paying in full the Exercise Price, plus
transfer taxes, if any. Payment of the Exercise Price shall be made in United
States currency, by certified check or money order payable to the order of the
Company.

      Upon certain events provided for in the Warrant Agreement, the Exercise
Price and the number of shares of Common Stock issuable upon the exercise of
each Warrant are required to be adjusted.

      The Warrants are subject to call for redemption by the Company at a price

Registered Holders.

      No Warrant may be exercised after 5:00 P.M. (New York City time) on the

      Prior to the Expiration Date, subject to any applicable laws, rules or
regulations restricting transferability and to any restriction on
transferability that may appear on this Warrant Certificate in accordance with
the terms of the Warrant Agreement hereinafter referred to, the Registered
Holder shall be entitled to transfer this Warrant Certificate in whole or in
part upon surrender of this Warrant Certificate at the office of the Warrant
Agent maintained for that purpose with the form of assignment set forth hereon

securities exchange, a commercial bank, a savings bank or a savings and loan
association or a trust company located in the United States, a member of the

institution which is a participant in a signature guarantee program (as such
terms are defined in Reg. 240.17Ad-15 under the Securities Exchange Act of 1934)
applicable to the Warrant Agent. Upon any such transfer, a new Warrant
Certificate or Warrant Certificates representing the same aggregate number of
Warrants will be issued in accordance with the instructions in the form of
assignment.

Warrant Certificate, there shall be issued to the Registered Holder a new
Warrant Certificate in respect of the Warrants not exercised.

exchange this Warrant Certificate, with or without other Warrant Certificates,
for another Warrant Certificate or Warrant Certificates for the same aggregate
number of Warrants, upon surrender of this Warrant Certificate at the office
maintained for such purpose by the Warrant Agent.

      No fractional shares will be issued upon the exercise of Warrants. As to
any final fraction of a share, which the registered holder of one or more
Warrant Certificates, the rights under which are exercised in the same
transaction, would otherwise be entitled to purchase upon such exercise, the
Company shall pay the cash value thereof determined as provided in the Warrant
Agreement.

      This Warrant Certificate is issued under and in accordance with a Warrant
Agreement between the Company and the Warrant Agent (the "Warrant Agreement")
and is subject to the terms and provisions contained in said Warrant Agreement,
to all of which terms and provisions the Registered Holder consents by
acceptance hereof.

      This Warrant Certificate shall not entitle the Registered Holder to any of
the rights of a stockholder of the Company, including, without limitation, the
right to vote, to receive dividends and other distributions, or to attend or
receive any notice of meetings of stockholders or any other proceedings of the

      Section 2.02. (1) The Warrant Holder may exercise this Warrant, in whole
or in part, to purchase shares of Common Stock or Underlying Warrants, or both,
in such amounts as may be elected upon surrender of this Warrant with the

                  (3) In case the Warrant Holder shall exercise this Warrant

                                   ARTICLE III

                       ADJUSTMENT OF SHARE PURCHASE PRICES
                           AND NUMBER OF COMMON SHARES

      Section 3.01. The Share Purchase Price at which this Warrant may be
exercised at any time specified in Section 1.01( ) to purchase Common Shares
shall be subject to adjustment from time to time as follows:

                  (1) If the Company shall (i) pay a dividend on its Common
Shares, (ii) subdivide its outstanding Common Shares or (iii) combine its
outstanding Common Shares into a smaller number of shares, the Share Purchase
Prices in effect immediately prior to each of those events shall be adjusted
proportionately so that the adjusted Share Purchase Prices will bear the same
relation to the Share Purchase Prices in effect immediately prior to the event
as the total number of Common Shares outstanding immediately prior to the event
will bear to the total number of Common Shares outstanding immediately after the
event. An adjustment made pursuant to this clause (1) shall become effective
immediately after the record date in the case of a dividend and immediately
after the effective date in the case of a subdivision or combination.

                  (2) If the Company hereafter (i) issues shares of Common Stock
for a consideration less than the then current market price per Share (as
defined in clause (4) below), (b) issues rights or warrants entitling the
holders to subscribe for or to purchase Common Shares at a price per Share less
than such market price, or (c) issues convertible securities convertible into
Shares of Common Stock at a price per Share less than such market price, then at
the record date of such event the Share Purchase Prices shall be


                                        4
<PAGE>   5
adjusted so that it will equal the price determined by multiplying the Share
Purchase Prices in effect immediately prior to the adjustment by a fraction, of
which the numerator shall be (i) the number of Common Shares outstanding on the
record date plus (ii) the number of additional Common Shares issued for such
consideration below such market price or a number of additional Common Shares
which the aggregate exercise price of such rights or warrants would be purchased
at such market price, or which would be received on the conversion of such
convertible securities the aggregate exercise price of the rights or warrants or
conversion price of such convertible securities would purchase at the current
market price per Common Share (as determined in accordance with the provisions
of clause (4) below), issued for such consideration below such market price or a
number of additional Common Shares which the aggregate exercise price of such
rights or warrants would be purchased at such market price, or which would be
received on the conversion of such convertible securities and of which the
denominator shall be (x) the number of Common Shares outstanding on the record
date plus (y) the number of Common Shares offered for subscription purchase or
issuable on conversion of such convertible securities. Each adjustment shall
become effective retroactively immediately after the record date for the
determination of Common Shares entitled to receive the rights or warrants.

                  (3) Except in the case of distributions of Common Shares
subject to preceding clause (1), or of rights or cash, or of warrants to
purchase Common Shares subject to preceding clause (2), if the Company
distributes to all holders of shares evidences of its indebtedness or assets
(excluding cash dividends or distributions) or rights or warrants to subscribe
for or to purchase shares, evidences of indebtedness or assets, then in each
such case the Share Purchase Prices shall be adjusted so it will be equal to the
price determined by multiplying the Share Purchase Prices in effect immediately
prior to the adjustment by a fraction, of which the numerator shall be (i) the
total number of outstanding Common Shares, multiplied by (ii) the current market
price per Common Share (as determined in accordance with the provisions of
clause (4) be on the record date mentioned below, or less (iii) the fair market
value (as determined by the Board of Directors, whose determination shall be
deemed conclusive, unless arbitrary or unreasonable, described in a statement
mailed to the Warrant Holder) of the capital stock, assets or evidences of
indebtedness, or rights or warrants, so distributed, and of which the
denominator shall be (x) the total number of outstanding Common Shares
multiplied by (y) the current market price per Common Share. Each adjustment
shall become effective retroactively immediately after the record date for the
determination of stockholders entitled to receive a distribution.

                  (4) For the purpose of any computation under clause (2) or
clause (3) above, the current market price per Common Share at any date shall be
deemed to be the average of the daily closing prices for the thirty consecutive
business days commencing forty-five business days before the day in question.
The closing price for each day shall be the last reported sales price regular
way or, in case no such reported sale takes place on that day, the average of
reported closing bid and asked prices regular way, either on the New York Stock
Exchange or the American Stock Exchange, or, if at any time the Common


                                      5
<PAGE>   6
Shares are not listed or fitted to trading on such Exchanges, on the principal
national cities exchange on which the Common Shares are listed or admitted to
trading, or if not listed or admitted to trading on national securities
exchange, the average of the highest reported bid and lowest reported asked
prices as furnished by the National Association of Securities Dealers Inc.'s
Automated Quotations System, or the nearest comparable system or, in the absence
of either, the fair market value as determined by the Board of Directors (whose
determination shall be deemed conclusive, unless arbitrary or unreasonable) and
described in a statement mailed to the Warrant Holder.

      No adjustment of the Share Purchase Prices shall be made if the amount of
the adjustment would be less than $.05, but any adjustment which would otherwise
be required to be made will be carried forward and be made at the time of and
together with the next subsequent adjustment which, together with all
adjustments so carried forward, amounts to $.05 or more.

      Section 3.02. Upon each adjustment pursuant to this Article III of the
Share Purchase Prices for any period specified in Section 1.01( ), the number of
Common Shares purchasable in any such period shall be adjusted to the number of
shares of Common Shares, calculated to the nearest one hundredth of a share,
obtained by multiplying the number of Common Shares purchasable in such period
on exercise of the Warrant immediately prior to the adjustment by the Share
Purchase Price for that period in effect prior to the Adjustment and dividing
the product so obtained by the new Share Purchase Price for that period.

      In case of such adjustment, this Warrant will represent, for each of the
aforesaid periods the right to purchase at the original Share Purchase Price for
the Common Shares for the applicable period the number of Common Shares or
fraction of such Share (depending on whether such Price is reduced or increased)
provided to be issued pursuant to the adjustment specified in this Section 3.02,
each of such Shares to be purchased at the Share Purchase Price for such period
provided for by the aforesaid adjustments to such Share Purchase Price.

      Section 3.03. In case of any capital reorganization of the Company or of
any reclassification of the Common Shares, or the consolidation of the Company
with any other corporation or entity, or sale of the properties and assets of
the Company as, or substantially as, an entirety to any other entity, this
Warrant will be exercisable after such capital reorganization, reclassification,
consolidation or sale, upon the terms and conditions specified in this
Agreement, for the number of Common Shares, other securities or property which
the Warrant Holder would have been entitled to receive upon the capital
reorganization, reclassification, consolidation or sale if this Warrant had been
exercised immediately before the first such capital reorganization,
reclassification, consolidation or sale. In the case of a merger of the Company
into or with any other corporation or entity (provided that on such merger
securities of the Company are changed into, changed for, or converted into
securities of any other issuer), after such merger, this Warrant shall be


                                      6
<PAGE>   7
exercisable, upon the terms and conditions specified in this Agreement. The
subdivision or combination of Common Shares at any time outstanding into a
greater or lesser number of Shares shall not be deemed to be a reclassification
of the Common Shares of the Company for the purposes of this Section 3.03. The
Company shall not effect any consolidation, merger or sale unless prior to or
simultaneously with its consummation the successor entity (if other than the
Company) resulting from the consolidation or merger or the entity purchasing the
Company's assets and any other entity the shares of stock or other securities or
property of which are receivable as a result of the transaction agree, by
written instrument executed and delivered to the Warrant Holder, to (i) the
obligation to deliver to the Warrant Holder the Common Shares or other
securities or property to which the Warrant Holder will be entitled on exercise
of this Warrant, and (ii) all other obligations of the Company under this
Agreement.

      Section 3.04. Whenever the Share Purchase Prices and the number of Common
Shares purchasable are adjusted as provided in this Article, the Company shall
compute the adjustment of the Share Purchase Prices and number of such shares
purchasable in each such period in accordance with Sections 3.01 and 3.02 and
shall prepare a certificate signed by its President or a Vice President and its
principal accounting officer setting forth the adjusted Share Purchase Prices
and number of such shares purchasable in each such period and showing in
reasonable detail the method of calculation of the adjustment and the facts
requiring the adjustment and upon which the calculation is based, and that
certificate shall forthwith be mailed to the Warrant Holder.

      Section 3.05. If at any time after the date of this Agreement:

                  (1) the Company shall declare a dividend (or any other
distribution) on its Common Shares payable otherwise than in cash out of its
earned surplus; or

                  (2) the Company shall authorize the granting to the Holders of
its Common Shares of rights to subscribe for or purchase any shares of capital
stock of any class or of any other rights; or

                  (3) the Company shall authorize any reclassification of its
Common Shares (other than a subdivision or combination of its outstanding Common
Shares), any capital reorganization, or any consolidation or merger to which it
is a party and for which approval of any stockholder of the Company is required,
or the sale or transfer of all or substantially all of its assets; or

                  (4)   events shall have occurred resulting in the voluntary or
involuntary dissolution, liquidation or winding up of the Company;

then the Company shall cause to be mailed to the Warrant Holder at least 20 days
(or 10 days in any case specified in clause (1) or (2) above) prior to the
applicable record date,


                                      7
<PAGE>   8
a notice stating the date on which a record is to be taken for the purpose of
the dividend, distribution or rights, or, if a record is not to be taken, the
date as of which the holders of record of Common Shares shall become or be
entitled to such dividend, distribution or rights or the date on which the
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up is expected to become effective, and the date as of
which it is expected that holders of Common Shares of record shall be entitled
to exchange their shares for securities or other property deliverable upon such
reclassification, consolidation, merger, sale, transfer, dissolution,
liquidation or winding up. Failure to give any such notice or any defect therein
shall not affect the validity of the proceeding referred to in clauses (1), (2),
(3) and (4) above.

      Section 3.06. The form of this Warrant need not be changed because any
change in the Share Purchase Prices or in the number of Common Shares
purchasable upon exercise of this Warrant pursuant to this Article and Warrants
issued after such change may state the same Share Purchase Prices and the same
number of Common Shares as are stated in the form of warrant initially issued
pursuant to this Agreement. However, the Company may at any time in its sole
discretion (which shall be conclusive) make any change in the form of this
Warrant that it may deem appropriate and that does not affect the substance
thereof; and any Representative's Warrant thereafter issued, whether in exchange
or substitution for an outstanding Representative's Warrant or otherwise, may be
in the form as so changed.


                                   ARTICLE IV

                          OTHER PROVISIONS RELATING TO
                            RIGHTS OF WARRANT HOLDER

      Section 4.01. The Warrant Holder, as such, shall not be entitled to vote
or receive dividends or be deemed the holder of Common Stock for any purpose,
nor shall anything contained in this Warrant be construed to confer upon the
Warrant Holder, as such, any of the rights of a stockholder of the Company or
any right to vote, give or withhold consent to any action by the Company
(whether upon any recapitalization, issue of stock, reclassification of stock,
consolidation, merger, conveyance or otherwise), receive notice of meetings or
other action affecting stockholders (except for notices provided for in this
Warrant), receive dividends or subscription rights, or otherwise until this
Warrant shall have been exercised to purchase Common Stock or to purchase
Underlying Warrants and such Underlying Warrants shall have become exercisable
and the Common Stock shall have become deliverable as provided in Article II or
pursuant to the terms of the Underlying Warrants, at which time the person or
persons in whose name or names the certificate or certificates for the Common
Stock being purchased shall be deemed the holder or holders of record of such
Common Stock for all purposes; provided, however, that any such exercise on any
date when the stock transfer books of the Company shall be closed shall
constitute the person or persons in whose name or names the certificate or
certificates for such shares


                                      8
<PAGE>   9
of Common Stock are to be issued as the record holder or holders thereof for all
purposes at the opening of business on the next succeeding day on which such
stock transfer books are open and this Warrant shall not be deemed to have been
exercised, in whole or in part as the case may be, until such next succeeding
day on which stock transfer books are open for the purpose of determining
entitlement to dividends on such shares of Common Stock, and such exercise shall
be at the actual Exercise Prices in effect at such date.

      Section 4.02. If this Warrant is lost, stolen, mutilated or destroyed, the
Company may, on such terms as it may in its discretion impose (which shall, in
the case of a mutilated Warrant, include the surrender thereof), issue a new
Warrant of like denomination and tenor as, and in substitution for, this
Warrant.

      Section 4.03. (1) The Company covenants and agrees that at all times it
shall reserve and keep available for the exercise of this Warrant such number of
authorized shares of Common Stock as are sufficient to permit the exercise in
full of this Warrant.

                  (2) Prior to the issuance of any Common Stock upon exercise of
this Warrant, the Company covenants and agrees to secure the listing of such
shares of Common Shares upon any securities exchange or automated quotation
system upon which such Common Stock is then listed.

                  (3) The Company covenants that all Common Stock issued on
exercise of this Warrant, will be validly issued, fully paid, nonassessable and
free of preemptive rights.

      Section 4.04. Anything contained herein to the contrary notwithstanding,
the Company shall not be required to issue any fractional shares of Common Stock
in connection with the exercise of this Warrant and other Warrants of like tenor
submitted for exercise concurrently herewith. In any case where the Warrant
Holder would, except for the provisions of this Section 4.04, be entitled under
the terms of this Warrant to receive a fraction of a share of Common Stock upon
the exercise of this Warrant, the Company shall, upon the exercise of this
Warrant and receipt of the Warrant Prices, issue the largest number of whole
shares purchasable upon exercise of this Warrant and any other like Warrants
tendered for exercise at the same time. The Warrant Holder, by the acceptance of
the Warrant, expressly waives his right to receive a certificate of any fraction
of a Common Share upon the exercise hereof. However with respect to any fraction
of a share called for upon any exercise hereof, the Company shall pay to the
Registered Holder an amount in cash equal to such fraction multiplied by the
current market value of such fractional share, determined as follows:

                  (1) if the Common Stock is listed on a national securities
            exchange or admitted to unlisted trading privileges on such exchange
            or listed for trading on the Nasdaq National Market System ("NMS"),
            the current market


                                      9
<PAGE>   10
            value shall be the last reported sale price of the Common Stock on
            such exchange or system on the last business day prior to the date
            of exercise; or

                  (2) if the Common Stock is listed in the over-the-counter
            market (other than on NMS) or admitted to unlisted trading
            privileges thereon, the current market value shall be the mean of
            the last reported bid and asked prices reported by the National
            Quotation Bureau, Inc. on the last business day prior to the date of
            the exercise; or

                  (3) if the Common Stock is not so listed or admitted to
            unlisted trading privileges and bid and asked prices are not so
            reported, the current market value shall be an amount determined in
            such reasonable manner as may be prescribed by the Board of
            Directors of the Company.

      Section 4.05. Notices to the Warrant Holder provided for in this Warrant
shall be deemed given or made by the Company if delivered or sent by mail,
certified or registered, return receipt requested, postage prepaid, addressed to
the Warrant Holder at his last known address as it shall appear on the books of
the Company.

                           TREATMENT OF WARRANT HOLDER


      Section 5.01. Prior to due presentment for registration of transfer of
this Warrant, the Company may deem and treat the Warrant Holder as the absolute
owner of this Warrant (notwithstanding any notation of ownership or other
writing hereon) for the purpose of any exercise hereof and for all other
purposes and the Company shall not be affected by any notice to the contrary.

                                   ARTICLE VI

                       SPLIT-UP, COMBINATION, EXCHANGE AND
                              TRANSFER OF WARRANTS

      Section 6.01. This Warrant may be split up, combined or exchanged for
another Warrant or Warrants of like tenor to purchase a like aggregate number of
shares of Common Stock. If the Warrant Holder desires to split up, combine or
exchange this Warrant, he shall make such request in writing delivered to the
Company at its office in New Providence, New Jersey and shall surrender this
Warrant and any other Warrants to be so split up, combined or exchanged at said
office. Upon any such surrender for a split-up, combination or exchange, the
Company shall execute and deliver to the person entitled thereto a Warrant or
Warrants, as the case may be, as so requested. The Company


                                       10
<PAGE>   11
may require such Warrant Holder to pay a sum sufficient to cover any tax or
governmental charge that may be imposed in connection with any split-up,
combination or exchange of Warrants.

      Section 6.02. Any assignment permitted hereunder shall be made by
surrender of this Warrant to the Company at its principal office with the Form
of Assignment annexed hereto duly executed and with funds sufficient to pay any
transfer tax. In such event the Company shall, without charge, execute and
deliver a new Warrant in the name of the assignee named in such instrument of
assignment and this Warrant shall promptly be canceled. This Warrant may be
divided or combined with other Warrants which carry the same rights upon
presentation thereof at the principal office of the Company together with a
written notice signed by the Warrant Holder, specifying the names and
denominations in which new Warrants are to be issued. Upon receipt by the
Company of evidence satisfactory to it of the loss, theft, destruction or
mutilation of this Warrant, and (in the case of loss, theft or destruction) of
reasonably satisfactory indemnification, and upon surrender and cancellation of
this Warrant, if mutilated, the Company will execute and deliver a new Warrant
of like tenor and date and any such lost, stolen or destroyed Warrant shall
thereupon become void. Any such new Warrant executed and delivered shall
constitute an additional contractual obligation on the part of the Company,
whether or not the Warrant so lost, stolen, destroyed or mutilated shall be at
any time enforceable by anyone.


                                   ARTICLE VII

                  REGISTRATION UNDER THE SECURITIES ACT OF 1933

registered mail, at least sixty (60) days prior to the filing of each such
registration statement, to the holders of this Warrant of the Underlying
Warrants, and of any shares of Common Stock issued on exercise of this Warrant
or the Underlying Warrants (collectively, the "Representative's Securities") of
its intention to do so. If any of the holders of such securities shall notify
the Company within twenty (20) days after receipt of any such notice of their
desire to include any such securities (including shares of Common Stock
issuable on exercise of any Warrants included in such Representative's
Securities) in such proposed registration statement, the Company shall afford
such holders the opportunity to have any such securities registered under such
registration statement. The Company agrees to give written notice of any such
proposed registration statement to any registered holder of any then
outstanding Representative's Securities and to JMS, at least (30) days prior to

<PAGE>   12
                  (2) Upon the written request of the then holders of at least
fifty percent (50%) in interest (taken as a single group) of the registered
holders of the Representative's Securities (the holder of any Warrant being
deemed for such purpose the holder of the Common Shares purchasable on exercise
of such Warrant) made not before ___________________ and not after
__________________, the Company shall file one post-effective amendment or new
registration statement as may be appropriate to cover a public offering of such
Securities (including any shares of Common Stock issuable on exercise of any
Warrants included in such Representative's Securities).

                   (3) The following provisions shall also be applicable to any
such post-effective amendment or registration statement:

                              (a) The holders whose Representative's Securities
are to be included therein (the "Sellers") shall furnish the Company with such
appropriate information (relating to the intentions of such holders) in
connection therewith as the Company shall reasonably request in writing.
Following the effective date of such post-effective amendment or registration
statement, the Company shall upon the request of any Seller forthwith supply
such number of prospectuses meeting the requirements of the Act as shall be
requested by such Seller to permit such Seller to make a public offering of all
the Representative's Securities held by such Seller or underlying any Warrants
held by such Seller. The Company shall use its best efforts to register such
securities for sale under the securities laws in such states as the Sellers
shall reasonably designate.

                              (b) All expenses incident to effectiveness of the
Registration Statement referred to in Section 7.01 including, but not limited
to, all registration and filing fees payable to the Securities and Exchange
Commission and the National Association of Securities Dealers, Inc., fees and
disbursements of counsel and independent public accountants printing and other
expenses, (excluding underwriting commissions and any fees and disbursements of
any counsel employed by any selling shareholders on their own behalf), shall be
borne (i) in the case of a Registration Statement filed pursuant to Section 
7.01(1) by the Company, any other selling stockholder and any Seller in
proportion to the number of shares of Common Stock respectively offered by them
therein (Warrants for such purpose being considered the equivalent of the shares
of Common Stock purchasable on exercise of such Warrants), and (ii) in the case
of a Registration Statement filed pursuant to Section 7.01 (2), by the Company
to the extent of $25,000 and the balance by the Sellers whose securities are
included in such registration statement pro rata in accordance with the shares
of Common Stock included by them therein (Warrants for such purpose being
considered equivalent to the Common Shares purchasable on exercise of such
Warrants).

                              (c) Prior to any public offering pursuant to
Section 7.01, the Company will register or qualify the securities under the
securities or Blue Sky laws of such jurisdictions as any Seller or any
underwriter may reasonably request in writing, and keep such registration or
qualification effective during the period such


                                       12
<PAGE>   13
Registration Statement is required to be kept effective, and do any and all acts
or things necessary or advisable to enable the disposition of the
Representative's Securities covered by the applicable Registration Statement,
provided that the Company shall not be required generally to do business in any
jurisdiction where it has not been so qualified, or to take any action which
would subject it to general service of process in any such jurisdiction where it
is not then so subject.

                              (d) The Company shall indemnify and hold harmless
each Seller and each underwriter, within the meaning of the Act, that may
purchase from or sell for any Seller any Representative's Securities from and
against any and all losses, claims, damages and liabilities caused by any true
statement or alleged untrue statement of a material fact in any registration
statement under the Act or any prospectus included therein required to be filed
or furnished pursuant to this Section 7.01, or caused by omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages or liabilities are caused by any such untrue statement
or omission based upon information furnished or required to be furnished in
writing to the Company by such Seller or underwriter expressly for use therein,
which indemnification shall include each person, if any, who controls any such
Seller or underwriter within the meaning of such Act; provided, however, that
the Company shall not be obliged to indemnify any such Seller or underwriter or
controlling person unless such Seller or underwriter shall at the same time
indemnify the Company, its directors, each officer signing the related
registration statement and each person, if any, who controls the Company within
the meaning of the Act from and against any and all losses, claims, damages and
liabilities caused by any untrue statement or alleged untrue statement of a
material fact contained in any registration statement or any prospectus required
to be filed or furnished by reason of this Section 7.01 or caused by any
omission or alleged omission to state therein a material fact or required to be
stated therein or necessary to make the statements therein not misleading,
insofar as such losses, claims, damages or liabilities are caused by any untrue
statement or alleged untrue statement or omission or alleged omission based upon
information furnished in writing to the Company by any such Seller or
underwriter expressly for use therein.

      The Company's agreements in this Section 7.01 shall continue in effect
regardless of the exercise and surrender of this Warrant.

      Section 7.02. Neither this Warrant nor the Securities issuable on exercise
t hereof may be sold or otherwise disposed of except as follows:

                  (a) to a person, who, in the opinion of counsel reasonably
satisfactory to the Company, is a person to whom such securities may legally be
transferred without registration and without the delivery of a current
prospectus under the Act with respect thereto and then only against receipt of
an agreement of such person to comply with the provisions of this Warrant with
respect to any resale or owner disposition of such securities; or


                                      13
<PAGE>   14
                  (b) to any person upon delivery of a prospectus then meeting
the requirements of the Act relating to such securities (as to which a
registration statement under the Act shall then be in effect) and the offering
thereof for such sale or disposition.

      Notwithstanding the above, this Warrant will be restricted from sale,
transfer, assignment or hypothecation for a period of one (1) year from the
effective date of the registration statement except to officers or partners of
JMS.

Dear Sirs:

        In connection with the registration under the Securities Act of 1933, as

par value $.01 per share (the "Common Stock"), of Barringer Technologies Inc., a
Delaware corporation (the "Company"), (ii) 1,437,500 warrants to purchase shares
of Common Stock (the "Purchase Warrants"), (iii) 359,375 shares of Common Stock

Warrant Shares"), (iv) 125,000 warrants to purchase shares of Common Stock and
Purchase Warrants (the "Underwriter's Warrants"), (v) 125,000 shares of Common

Barringer Technologies Inc.                                     October 31, 1996

examined such corporate records, certificates and other documents, and such
questions of law, as we have considered necessary or appropriate for the
purposes of this opinion.

        Upon the basis of such examination, we advise you that, in our opinion:

        1.      When the Registration Statement has become effective under the
Act, the terms of the issue and sale of the Shares have been duly established
in conformity with the Company's Certificate of Incorporation, as amended, so
as not to violate any applicable law or result in a breach of any agreement or
instrument binding on the Company and so as to comply with any requirement or
restriction imposed by any court or governmental body having jurisdiction over
the Company, and the Shares have been duly issued and sold as contemplated in
the Registration Statement, the Shares will be validly issued, fully paid and
non-assessable.

        2.      When the Registration Statement has become effective under the
Act, the Warrant Agreement relating to the Purchase Warrants has been duly
authorized, executed and delivered, the terms of the Purchase Warrants and of
their issuance and sale have been duly established in conformity with the
Warrant Agreement so as not to violate any applicable law or result in a breach
of any agreement or instrument binding upon the Company and so as to comply
with any requirement or restriction imposed by any court or governmental body
having  jurisdiction over the Company, and the Purchase Warrants have been duly
executed and authenticated in accordance with the Warrant Agreement and issued
and sold as contemplated by the Registration Statement, the Purchase Warrants
will constitute valid and legally binding obligations of the Company, subject
to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and
similar laws of general applicability relating to or affecting creditors'
rights and to general equity principles.

        3.      When the Registration Statement has become effective under the
Act, the terms of the Underwriter's Warrants and of their issuance and sale
have been duly established so as not to violate any applicable law or result in
a breach of any agreement or instrument binding upon the Company and so as to
comply with any requirement or restriction imposed by any court or governmental
body having jurisdiction over the Company, and the Underwriter's Warrants have
been duly executed and authenticated in accordance with the terms of the
Underwriter's Warrants and issued and sold as contemplated by the Registration
Statement, the Underwriter's Warrants will constitute valid and legally binding
obligations of the Company, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability
relating to or affecting creditors' rights and to general equity principles.

        4.      Subject to the opinion set forth in paragraph 2 above, when the
Underwriter's Purchase Warrants have been duly issued as contemplated in the
Registration Statement upon the due exercise of the Underwriter's Warrants, and
the Company has received payment in full of the exercise price therefor, the
Underwriter's Purchase Warrants will constitute valid and legally binding
obligations of the Company, subject to bankruptcy, insolvency,

fraudulent transfer, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors' rights and to general equity
principles. 

        5.      When the Purchase Warrant Shares, the Underwriter's Warrant
Shares and the Underwriter's Purchase Warrant Shares have been duly issued as
contemplated in the Registration Statement and the Warrant Agreement upon the
due exercise of the Purchase Warrants, the Underwriter's Warrants and the

fully paid and non-assessable.

<PAGE>   3
during which such termination occurs. In addition, the Executive or his legal
representative shall be entitled to any accrued and unpaid vacation including
any allowable carry over, and to the pro-rata portion of any compensation due
pursuant to Section 3.2 that is earned in the year of death or legal incapacity.

                  5.2 The Company, may at its option, terminate the Executive's
employment under this Agreement if the Executive shall fail, or if the Board of

for a period of ninety (90) consecutive days or more during any two hundred

                  5.3 (a) The Company may terminate the Executive's employment
hereunder at any time for "cause", which includes but is not limited to the
following reasons:

                  i.     an act or acts of dishonesty on the part of the 
Executive constituting a felony or resulting or intended to result directly or 
indirectly in gains or personal enrichment at the expense of the Company;

                  ii.    the continued willful failure by the Executive to
perform substantially his duties with the Company (other than any such failure
resulting from his incapacity due to physical injury or physical or mental
illness) or a continuing material breach by the Executive of his obligations
hereunder for a period of thirty (30) days after a demand for substantial
performance is delivered to the Executive on behalf of the Board of Directors
which specifically identifies the manner in which the Board of Directors
believes that the Executive has not substantially performed his duties;

                  iii.   willful abuse of corporate power, willful neglect or
willful misconduct in the performance of the Executive's duties and obligations
to the Company.

                      (b) For purposes of clauses ii and iii of Section 5.3(a),
no act, or failure to act, on the part of the Executive shall be considered
"willful" unless done or omitted to be done by the Executive without reasonable
belief in good faith that his action or omission was in, or not opposed to, the
best interests of the Company. Any act, or failure to act, based upon authority
given pursuant to a resolution duly adopted by the Board or based upon the
advice of counsel for the Company shall be conclusively presumed to have been
done or omitted to have been done by the Executive in good faith and in the best
interests of the Company, unless such action by the Board of Directors was taken
upon the recommendation of the Executive upon information provided by the
Executive which the Executive knew to be false or upon the omission of material
facts by the Executive, which facts


                                  Page 3 of 10
<PAGE>   4
would have been adverse to the Executive's recommendation.

         In such event, the Executive or his legal representative shall be
entitled to that portion of his Current Salary accrued to or payable as of the
date of termination. In addition, the Executive shall be entitled to any accrued
and unpaid vacation including any allowable carryover.

                  5.4 The Company may terminate the Executive's employment
hereunder at any time, with or without cause, upon at least thirty (30) days
prior written notice to the Executive. In such event, the Executive or his legal
representative shall be entitled to receive his Current Salary until the
applicable Agreement Expiration Date and the pro-rata portion of any
compensation due pursuant to Section 3.2 that is earned in the year of such
termination. In addition, the Executive shall be entitled to any accrued and
unpaid vacation including any allowable carryover.

                  5.5 The Executive may voluntarily terminate the Executive's
employment hereunder at any time without cause upon at least ninety (90) days
prior written notice to the Company. Upon receipt of the ninety (90) day notice,
the Company may, at its option, terminate the Executive during such ninety (90)
day period. In such event, the Executive or his legal representative shall be
entitled to that portion of his Current Salary accrued to or payable as of the
date of termination. In addition, the Executive shall be entitled to any accrued
and unpaid vacation including any allowable carry over.

                  5.6 The severance payments described in Section 6 ("Severance
Award") shall be payable to the Executive if Executive's employment with the
Company terminates during the term of this Agreement or, if the Company does not
renew this agreement such non-renewal will be deemed to be a termination without
cause, or for any of the following reasons:

         (a)      involuntarily, other than pursuant to Sections 5.1, 5.2, 5.3
and 5.5; or

         (b)      voluntarily within 90 days, following:

                  i.     any reduction in Executive's Current Salary other than
pursuant to a general reduction of Executives' salaries; or

                  ii.    any material reduction in the benefits provided to the
Executive pursuant to Sections 3.2, 3.3 and 4. It is the intent that this
provision will in no way limit the ability of the Company to reasonably alter,
which would include a reasonable reduction in benefits on account of a Change in
Control without triggering the Severance Award, provided that any such
alteration is uniformly applied to all similarly situated executives; or

                  iii.   any relocation to which Executive has not agreed to an
office of the Company or related entity more than sixty (60) miles from the
office where the Executive was located at the time of the Change in Control or
any increase in Executive's required travel amounting to a constructive
relocation; or



                                  Page 4 of 10
<PAGE>   5
                  iv.    following a Change in Control, any material reduction
in the level of responsibility, position (including status, office, title,
reporting relationships or working conditions), authority or duties of the
Executive with the Company from that as existed within ninety (90) days
preceding the date of Change in Control. The intent of this provision is that
the Executive, following a Change in Control, will have a materially comparable
position with the Company or a successor or related entity as existed within
ninety (90) days preceding the date of Change in Control and that changes in
level of responsibility, position, authority or duties which are consistent with
the Change in Control will not be construed as constituting a material
reduction. If Executive believes that a material change has occurred, Executive
shall provide the Company or a successor or related entity with a notice and a
reasonable opportunity to cure (not to exceed forty-five (45) business days); or

         (c). voluntarily within 90 days if, following a Change in Control, the
Company or any successor of the Company either announces that it will not honor
or cause the Company or any successor of the Company to not honor the terms of
this Agreement, or if the Company or any successor of the Company or related
entity at any time fails to confirm in writing to Executive, within forty-five
(45) business days of a request by the Executive, that it will honor the terms
of this agreement.

         6.       Severance Award:

                  The Severance Award, which shall be in lieu of additional
payments under this Agreement, shall consist of the following:

                  6.1 The Executive will be paid a sum (in equal monthly
installments) equal to the product of one month's Current Salary times the
number of years, including fractional years, employed by the Company or any of
its successor or affiliates not to exceed six (6) months Current Salary;
provided that, in the event the Executive's employment is terminated pursuant to
Section 5.6(b) or 5.6(c), the Executive will be paid a sum (in equal monthly
installments) equal to the product of two months Current Salary times the number
of years, including fractional years, employed by the Company or any of its
successor or affiliates. Such amount not to exceed twelve (12) months Current
Salary. Payments shall commence not later than thirty (30) days after the
Executive's date of termination.

                  6.2 All payments received pursuant to Section 5 or this
Section 6 shall be treated as salary for purposes of the Company's 401(k)
Savings Plan to the extent permitted by law.

                  6.3 Any amounts owed to the Company or any of its successors,
pursuant to the Employee Stock Option Exercise Plan, shall be canceled as to
interest and principal upon return by the Executive of the common stock securing
such obligations.

                  6.4 The Executive will receive continuation of all benefits
being provided at the time of termination pursuant to Section 4 for the number
of months computed by multiplying the number of full and fractional years
employed by the Company times two (2) but not to exceed twelve (12)


                                  Page 5 of 10

months.

                  6.5 Following a Change in Control, the Executive will fully
vest in any stock options or equity equivalents held by the Executive that are
not fully vested and exercisable on the Executive's date of termination. Should
any stock option or equity equivalent document contain a Change in Control
clause, then such clause shall supercede this clause 6.5.

         7.       Confidential Information:

                  7.1 The Executive agrees not to disclose, either while in the
Company's employ or at any time thereafter, to any person not employed by the
Company or not engaged to render services to the Company, except with the prior
consent of the Board of Directors of the Company, any confidential information
obtained by him while in the employ of the Company, including, without
limitation, information relating to any of the Company's inventions, processes,
plans, devices, compilations of information, methods of distribution, customers,
client relationships, marketing strategies or trade secrets; provided, however,
that this provision shall not apply to any information or data which hereafter
becomes public information and shall not preclude the Executive from use or
disclosure of information for proper business purposes during the term of his
employment or from disclosure required by law or court order. This Section 7.1
shall be in addition to, and not in limitation or derogation of, any obligations
otherwise imposed by law upon the Executive in respect of confidential
information and trade secrets of the Company.

                  7.2 The Executive also agrees that, upon leaving the Company's
employ, he will not take with him, without the prior written consent of an

Company, and he will surrender to the Company, any record, list, drawing,
blueprint, specification or other document or property of the Company, together
with any copy and reproduction thereof, mechanical or otherwise, which is of a
confidential nature relating to the Company, or, without limitation, relating to
its or their methods of distribution, client relationships, marketing strategies
or any description of inventions, devices or processes, or which was produced,
developed or obtained by him or entrusted to him during the course of his
employment with the Company.

                  7.3 Should the Executive breach the terms and conditions of
Sections 7.1 and 7.2, then all amounts being paid pursuant to Section 6 shall be
terminated.

                  5.1 The Executive's employment under this Agreement shall

<PAGE>   3
during which such termination occurs. In addition, the Executive or his legal
representative shall be entitled to any accrued and unpaid vacation including
any allowable carry over, and to the pro-rata portion of any compensation due
pursuant to Section 3.2 that is earned in the year of death or legal incapacity.

                  5.2 The Company, may at its option, terminate the Executive's
employment under this Agreement if the Executive shall fail, or if the Board of
Directors shall find on the basis of medical evidence reasonably satisfactory to
it that the Executive is unable, by virtue or reason of physical injury or
physical or mental illness, to perform his duties hereunder on a full-time basis
for a period of ninety (90) consecutive days or more during any two hundred
seventy (270) day period or that the Executive's group and supplemental

termination. In addition, the Executive shall be entitled to any accrued and
unpaid vacation including allowable carry over, and to the pro-rata portion of
any compensation due pursuant to Section 3.2 that is earned in the year of such
termination.

                  5.3 (a) The Company may terminate the Executive's employment
hereunder at any time for "cause", which includes but is not limited to the
following reasons:

                  i.     an act or acts of dishonesty on the part of the 
Executive constituting a felony or resulting or intended to result directly or 
indirectly in gains or personal enrichment at the expense of the Company;

                  ii.    the continued willful failure by the Executive to
perform substantially his duties with the Company (other than any such failure
resulting from his incapacity due to physical injury or physical or mental
illness) or a continuing material breach by the Executive of his obligations
hereunder for a period of thirty (30) days after a demand for substantial
performance is delivered to the Executive on behalf of the Board of Directors
which specifically identifies the manner in which the Board of Directors
believes that the Executive has not substantially performed his duties;

                  iii.   willful abuse of corporate power, willful neglect or
willful misconduct in the performance of the Executive's duties and obligations
to the Company.

                      (b) For purposes of clauses ii and iii of Section 5.3(a),
no act, or failure to act, on the part of the Executive shall be considered
"willful" unless done or omitted to be done by the Executive without reasonable
belief in good faith that his action or omission was in, or not opposed to, the
best interests of the Company. Any act, or failure to act, based upon authority
given pursuant to a resolution duly adopted by the Board or based upon the
advice of counsel for the Company shall be conclusively presumed to have been
done or omitted to have been done by the Executive in good faith and in the best
interests of the Company, unless such action by the Board of Directors was taken
upon the recommendation of the Executive upon information provided by the
Executive which the Executive knew to be false or upon the omission of material
facts by the Executive, which facts


                                  Page 3 of 10
<PAGE>   4
would have been adverse to the Executive's recommendation.

         In such event, the Executive or his legal representative shall be
entitled to that portion of his Current Salary accrued to or payable as of the
date of termination. In addition, the Executive shall be entitled to any accrued
and unpaid vacation including any allowable carryover.

                  5.4 The Company may terminate the Executive's employment
hereunder at any time, with or without cause, upon at least thirty (30) days
prior written notice to the Executive. In such event, the Executive or his legal
representative shall be entitled to receive his Current Salary until the
applicable Agreement Expiration Date and the pro-rata portion of any
compensation due pursuant to Section 3.2 that is earned in the year of such
termination. In addition, the Executive shall be entitled to any accrued and
unpaid vacation including any allowable carryover.

                  5.5 The Executive may voluntarily terminate the Executive's
employment hereunder at any time without cause upon at least ninety (90) days
prior written notice to the Company. Upon receipt of the ninety (90) day notice,
the Company may, at its option, terminate the Executive during such ninety (90)
day period. In such event, the Executive or his legal representative shall be
entitled to that portion of his Current Salary accrued to or payable as of the
date of termination. In addition, the Executive shall be entitled to any accrued
and unpaid vacation including any allowable carry over.

                  5.6 The severance payments described in Section 6 ("Severance
Award") shall be payable to the Executive if Executive's employment with the
Company terminates during the term of this Agreement or, if the Company does not
renew this agreement such non-renewal will be deemed to be a termination without
cause, or for any of the following reasons:

         (a)      involuntarily, other than pursuant to Sections 5.1, 5.2, 5.3
and 5.5; or

         (b)      voluntarily within 90 days, following:

                  i.     any reduction in Executive's Current Salary other than
pursuant to a general reduction of Executives' salaries; or

                  ii.    any material reduction in the benefits provided to the
Executive pursuant to Sections 3.2, 3.3 and 4. It is the intent that this
provision will in no way limit the ability of the Company to reasonably alter,
which would include a reasonable reduction in benefits on account of a Change in
Control without triggering the Severance Award, provided that any such
alteration is uniformly applied to all similarly situated executives; or

                  iii.   any relocation to which Executive has not agreed to an
office of the Company or related entity more than sixty (60) miles from the
office where the Executive was located at the time of the Change in Control or
any increase in Executive's required travel amounting to a constructive
relocation; or



                                  Page 4 of 10
<PAGE>   5
                  iv.    following a Change in Control, any material reduction
in the level of responsibility, position (including status, office, title,
reporting relationships or working conditions), authority or duties of the
Executive with the Company from that as existed within ninety (90) days
preceding the date of Change in Control. The intent of this provision is that
the Executive, following a Change in Control, will have a materially comparable
position with the Company or a successor or related entity as existed within
ninety (90) days preceding the date of Change in Control and that changes in
level of responsibility, position, authority or duties which are consistent with
the Change in Control will not be construed as constituting a material
reduction. If Executive believes that a material change has occurred, Executive
shall provide the Company or a successor or related entity with a notice and a
reasonable opportunity to cure (not to exceed forty-five (45) business days); or

         (c). voluntarily within 90 days if, following a Change in Control, the
Company or any successor of the Company either announces that it will not honor
or cause the Company or any successor of the Company to not honor the terms of
this Agreement, or if the Company or any successor of the Company or related
entity at any time fails to confirm in writing to Executive, within forty-five
(45) business days of a request by the Executive, that it will honor the terms
of this agreement.

         6.       Severance Award:

                  The Severance Award, which shall be in lieu of additional
payments under this Agreement, shall consist of the following:

                  6.1 The Executive will be paid a sum (in equal monthly
installments) equal to the product of one month's Current Salary times the
number of years, including fractional years, employed by the Company or any of
its successor or affiliates not to exceed six (6) months Current Salary;
provided that, in the event the Executive's employment is terminated pursuant to
Section 5.6(b) or 5.6(c), the Executive will be paid a sum (in equal monthly
installments) equal to the product of two months Current Salary times the number
of years, including fractional years, employed by the Company or any of its
successor or affiliates. Such amount not to exceed twelve (12) months Current
Salary. Payments shall commence not later than thirty (30) days after the
Executive's date of termination.

                  6.2 All payments received pursuant to Section 5 or this
Section 6 shall be treated as salary for purposes of the Company's 401(k)
Savings Plan to the extent permitted by law.

                  6.3 Any amounts owed to the Company or any of its successors,
pursuant to the Employee Stock Option Exercise Plan, shall be canceled as to
interest and principal upon return by the Executive of the common stock securing
such obligations.

                  6.4 The Executive will receive continuation of all benefits
being provided at the time of termination pursuant to Section 4 for the number
of months computed by multiplying the number of full and fractional years
employed by the Company times two (2) but not to exceed twelve (12)


                                  Page 5 of 10

months.

                  6.5 Following a Change in Control, the Executive will fully
vest in any stock options or equity equivalents held by the Executive that are
not fully vested and exercisable on the Executive's date of termination. Should
any stock option or equity equivalent document contain a Change in Control
clause, then such clause shall supercede this clause 6.5.

         7.       Confidential Information:

                  7.1 The Executive agrees not to disclose, either while in the
Company's employ or at any time thereafter, to any person not employed by the
Company or not engaged to render services to the Company, except with the prior
consent of the Board of Directors of the Company, any confidential information
obtained by him while in the employ of the Company, including, without
limitation, information relating to any of the Company's inventions, processes,
plans, devices, compilations of information, methods of distribution, customers,
client relationships, marketing strategies or trade secrets; provided, however,
that this provision shall not apply to any information or data which hereafter
becomes public information and shall not preclude the Executive from use or
disclosure of information for proper business purposes during the term of his
employment or from disclosure required by law or court order. This Section 7.1
shall be in addition to, and not in limitation or derogation of, any obligations
otherwise imposed by law upon the Executive in respect of confidential
information and trade secrets of the Company.

                  7.2 The Executive also agrees that, upon leaving the Company's
employ, he will not take with him, without the prior written consent of an
officer authorized to act in the matter by the Board of Directors of the
Company, and he will surrender to the Company, any record, list, drawing,
blueprint, specification or other document or property of the Company, together

confidential nature relating to the Company, or, without limitation, relating to
its or their methods of distribution, client relationships, marketing strategies
or any description of inventions, devices or processes, or which was produced,
developed or obtained by him or entrusted to him during the course of his
employment with the Company.

                  7.3 Should the Executive breach the terms and conditions of
Sections 7.1 and 7.2, then all amounts being paid pursuant to Section 6 shall be
terminated.

hereunder to any entity with which it may merge or consolidate or to which it
may sell all or substantially all of its assets provided said entity shall
