                              TERMINATION AGREEMENT

     THIS AGREEMENT is made and entered into this 7th day of October, 1996, by
and among BARRINGER LABORATORIES, INC., a Delaware corporation ("Barringer"),
and BARRINGER TECHNOLOGIES, INC., a Delaware corporation, ("BTI").  Barringer
and BTI may be referred to herein collectively as "Parties."

     WHEREAS, pursuant to the Stock Purchase Agreement dated December 8, 1995 
(the "1995 Agreement").  BTI sold, and Barringer purchased, 647,238 shares of
Barringer Laboratories, Inc. common stock; and

     WHEREAS, under the terms of the 1995 Agreement, BTI granted Barringer a
perfected security interest in 88,260 ("Collateral") of the 432,475 shares of
the Barringer Laboratories, Inc. stock which it continued to hold (the
"Remaining Shares"), to secure certain covenants and agreements of BTI under the
1995 Agreement; and

     WHEREAS, in order to maximize Barringer's ability to utilize its net
operating loss carryforwards, BTI agreed in the 1995 Agreement to certain
restrictions upon the further sale and transfer of the Remaining Shares,
including the grant to Barringer of a right of first refusal with respect to the
Remaining Shares; and

     WHEREAS, BTI now desires the removal and release of these restrictions on
transferability in order to sell the Remaining Shares; and

     WHEREAS, in consideration of BTI's transfer and assignment of the 
Collateral to Barringer and of the other terms and conditions of this Agreement,
Barringer will agree to the removal and release of these restrictions on 
transferability to the extent set forth herein and Barringer has filed a 
registration statement under form S-3 with the Securities and Exchange 
Commission to facilitate any desired sale of the Remaining Shares in compliance 
with the terms of this Agreement.

     NOW, THEREFORE, in consideration of these Recitals and the provisions and
the respective agreements hereinafter set forth, the Parties hereto hereby agree
as follows:

     1.  REMOVAL AND RELEASE OF PRIOR RESTRICTIONS.  Upon the terms and subject 
to the conditions set forth in this Agreement, Barringer hereby:

         1.1  Waives and releases the restrictions on transferability set forth
     in Section 4.4 of the 1995 Agreement respecting the 344,215 shares of the 
     Barringer Laboratories, Inc. stock which BTI holds.  Barringer agrees to 
     take all action reasonably necessary to cause the reissuance of the stock
     certificate(s) evidencing such shares without the restrictive legend noting
     the existence of the restrictions set forth in the 1995 Agreement.

        1.2  Waives and releases the right granted by BTI in Section 4.5 of the
     1995 Agreement to Barringer of a first right to purchase any portion of the
     432,475 shares of the Barringer Laboratories, Inc. stock owned by BTI upon
     the same terms and conditions of a bona fide offer received by BTI.

<PAGE>

     2.  TRANSFER AND ASSIGNMENT OF COLLATERAL. Subject to the terms and 
conditions set forth herein, BTI hereby sells, assigns, and transfers to 
Barringer all of the 88,260 issued and outstanding shares of Barringer's 
common stock comprising the Collateral, free and clear of all liens, 
encumbrances and adverse claims of whatsoever kind or nature.  BTI shall 
deliver to Rumler Law Corporation, PC, as set forth in Section 4, below, a 
stock assignment in form satisfactory to Barringer, with a medallion 
certified signature stamp, sufficient to transfer title to such shares (the 
Collateral) to Barringer.

     3.   RESTRICTIONS ON FUTURE SALE, ASSIGNMENT AND TRANSFER.  The parties 
acknowledge and agree that it is their intention to maximize Barringer's 
ability to utilize its net operating loss carryforwards following the sale of 
all or any portion of the 432,475 shares (plus 5,000 additional shares 
purchased by BTI since the 1995 Agreement) of the Barringer Laboratories, 
Inc. stock which it continues to hold and which are not to be transferred to 
Barringer hereunder. Therefore, as a condition to the releases and waivers 
described in Section 1 above, BTI agrees that:

          3.1  For a period of three (3) months following the date of this 
     Agreement, and subject to the restriction set forth in Subsection 3.2, 
     immediately below, BTI agrees that it shall not, nor shall it have any 
     right to, knowingly sell, assign, transfer or otherwise dispose of more
     than 75,000 shares of the Barringer Laboratories, Inc. stock which it owns
     to any single purchaser or any affiliated purchasers, without the prior 
     written consent of Barringer, which Barringer may grant or deny in its 
     sole and absolute discretion.  For purposes of this Agreement, "affiliated 
     purchasers" shall mean purchasers who, directly or indirectly, influence, 
     control, are controlled by or are under common control, management or 
     ownership, with each other.  Affiliated Purchasers shall include but not be
     limited to voting trusts, relatives of any purchasers, and any director or 
     officer of a purchaser.

          3.2  For a period of three (3) months following the date of this 
     Agreement, and subject to the restriction set forth in Subsection 3.1, 
     immediately above, BTI agrees (i) that it shall not, nor shall it have any
     right to, sell, assign, or transfer any such shares at a price less than 
     One and 11/16 Dollars ($1.6875) per share; and (ii) that in the event it 
     receives an offer to purchase such shares at a price equal to or higher 
     than the price set forth in 3.2(i), above, BTI shall be required to sell,
     assign or transfer such shares, subject to the other restrictions set forth
     in this Agreement.

Nothing contained herein shall limit BTI's right or ability to exercise those 
certain warrants to purchase additional shares of the common stock of Barringer 
according to the terms and conditions set forth in the WARRANTS TO PURCHASE 
COMMON STOCK OF BARRINGER LABORATORIES, INC. dated August 29, 1996.  BTI 
understands and agrees that the subsequent sale by BTI of the shares received 
upon the exercise of such warrants, if so exercised, shall be subject to the 
terms, conditions and restriction set forth in this Agreement, and shall be 
subject to such other restrictions as provided under applicable state and 
federal securities laws.  Any sale, assignment, transfer or other disposition 
of shares of Barringer Laboratories, Inc. stock owned by BTI in contravention of
the terms of this Agreement shall be null and void.

     4.   CONSUMMATION OF RELEASE AND TRANSFER.  As provided in Section 2 
above, BTI shall forward to Rumler Law Corporation, PC, the stock assignment 
in form satisfactory to Barringer, with a medallion certified signature 
stamp, sufficient to transfer title to the Collateral to Barringer.  Upon the 
subsequent receipt by Rumler Law Corporation PC (i) of executed copies of 
this Agreement from each of the Parties; and (ii) of notice, in the form 
satisfactory to Rumler Law Corporation, PC., of the proper consent of the 
Board of Directors of Barringer,

                                      2

<PAGE>

harmless BTI against any and all loss, claim, damage or liability, joint or
several, to which BTI may become subject, under the Securities Act or otherwise,
insofar as such loss, claim, damage, or liability (or action with respect
thereto) arises out of or is based upon (a) any untrue statement or alleged
untrue statement of a material fact contained (i) in the Registration Statement,
the Effective Prospectus in respect of the Registration Statement; or (b) the
omission or alleged omission to state in the Registration Statement, the
Effective Prospectus or any amendment or supplement thereto of a material fact
required to be stated therein or necessary to make the statements therein not
misleading; and shall reimburse BTI for any legal or other reasonable expenses
incurred by it in connection with investigating or defending against in
connection with any such loss, claim, damage, liability or action,
notwithstanding the possibility that payments for such expenses might later be
held to be improper, in which case the person receiving them shall promptly
refund them; except that the Barringer shall not be liable in any such case to
the extent, but only to the extent, that any such loss, claim, damage, or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in reliance upon and in
conformity with written information furnished to the Barringer through BTI by or
on behalf of BTI specifically for use in the preparation of the Registration
Statement, the Effective Prospectus or any amendment or supplement thereto.

               7.5  RIGHT TO PROVIDE DEFENSE.  Promptly after receipt by an
indemnified party under Section 7.3 and/or 7.4 above of written notice of the
commencement of any action, the indemnified party shall, if a claim in respect
thereof is to be made against the indemnifying party under such section, notify
the indemnifying party in writing of the claim or the commencement of that
action; the failure to notify the indemnifying party shall not relieve it of any
liability which it may have to an indemnified party, except to the extent that
the indemnifying party did not otherwise have knowledge of the commencement of
the action and the indemnifying party's ability to defend against the action was
prejudiced by such failure.  Such failure shall not relieve the indemnifying
party from any other liability which it may have to the indemnified party.  If
any such claim or action shall be brought against an indemnified party, and it
shall notify the indemnifying party thereof, the indemnifying party shall be
entitled to participate therein and, to the extent that it wishes, jointly with
any other similarly notified indemnifying party, to assume the defense thereof
with counsel reasonably satisfactory to the indemnified party.  After notice
from the indemnifying party to the indemnified party of its election to assume
the defense of such claim or action, the indemnifying party shall not be
liable to the indemnified party under such section for any legal or other
expenses subsequently incurred by the indemnified party in connection with the
defense thereof other than reasonable costs of investigation.

               7.6  CONTRIBUTION.  If the indemnification provided for in
Section 7.4.2 herein is unavailable or insufficient to hold harmless an
indemnified party, then each indemnifying party shall contribute to the amount
paid or payable by such indemnified party as a result of the losses, claims,
damages, or liabilities referred to in Section 7.4.2 above (a) in such
proportion as is appropriate to reflect the relative benefits received by the
Barringer on one hand and BTI on the other from the offering of the securities;
or (b) if the allocation provided by clause (a) above is not permitted by
applicable law, in such proportion as is appropriate to reflect the relative
benefits referred to in clause (a) above but also the relative fault of the
Barringer on the one hand and BTI on the other in connection with the statements
or omissions which resulted in such losses, claims, damages, or liabilities, as
well as any other relevant equitable considerations.  The relative benefits
received by the Barringer and BTI shall be deemed to be in the same proportion
as the total net proceeds from the offering (before deducting expenses) received
by the Barringer bear to the total sales price and received by BTI.  Relative
fault shall be determined by reference to, among other things, whether the
untrue statement of a material fact or the omission to state a material fact
relates to information supplied by the Barringer or BTI and the parties'
relative intent, knowledge, access to information, and opportunity to correct or


                                      5

<PAGE>

prevent such untrue statement or omission.  For purposes of this Section 7.6, 
the term "damages" shall include any counsel fees or other expenses 
reasonably incurred by the Barringer or BTI in connection with investigating 
or defending any action or claim which is the subject of the contribution 
provisions of this Section 7.6. No person adjudged 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.

          Each party entitled to contribution agrees that upon the service of a
summons or other initial legal process upon it in any action instituted against
it in respect of which contribution may be sought, it shall promptly give
written notice of such service to the party or parties from whom contribution
may be sought, but the omission so to notify such party or parties of any such
service shall not relieve the party from whom contribution may be sought from
any obligation it may have hereunder or otherwise (except as specifically
provided in Section 7.6 hereof).

any Party hereto of a breach of any provision hereunder shall not operate or be
construed as a waiver of any prior or subsequent breach of the same or any other
