         STOCK PURCHASE AGREEMENT dated September 4, 1997 (herein, together
with the Schedules and Exhibits attached hereto, referred to as the
"Agreement") by and among Questron Technology, Inc., a Delaware corporation
("Questron"), and the shareholders of AR Acquisition Company, a Pennsylvania
corporation (the "Company"), listed on Schedule 1.1 ("Sellers").


                             W I T N E S S E T H :

         WHEREAS, Sellers are the beneficial and record holders of all of the
shares of capital stock of the Company (the "Shares"); and

         WHEREAS, Sellers wish to sell and Questron wishes to purchase the
Shares upon the terms and subject to the conditions contained in this
Agreement.

         NOW, THEREFORE, in reliance upon the representations and warranties
made herein and in consideration of the mutual agreements herein contained, the
parties agree as follows:


                                   ARTICLE 1

                          SALE AND PURCHASE OF SHARES

         1.1 Sale of Shares. At the Closing provided for in Section 2.1, each
Seller shall sell to Questron (or in Questron's sole discretion, any subsidiary
of Questron) the Shares beneficially owned by such Seller as set forth in
Schedule 1.1, and Questron shall purchase such Shares for the aggregate
purchase consideration specified in Section 1.2.

         1.2 Purchase Consideration and Payment for Shares. Questron shall
acquire 100% of the issued and outstanding stock of the Company, which will
consist of the Initial Purchase Price and the Deferred Purchase Price, as
defined below.

         (a) Initial Purchase Price. The "Initial Purchase Price" will be
payable by delivery of an aggregate of 100,000 shares of Questron's common
stock ("Questron Common Stock") to the Sellers in the proportions set forth in
Schedule 1.1. Each of the Seller's ownership rights in the Questron Common
Stock shall vest during the three (3) full calendar years immediately following
the Closing as follows: 20,000 of said shares upon the attainment by the
Company of $350,000 of pre-tax earnings in any of calendar years 1998, 1999 or
2000 up to the maximum of 100,000 shares upon the attainment of $750,000 of
pre-tax earnings in any of such years. In the event that pre-tax earnings are
more than $350,000 but less than $750,000 in any of such years, then the number
of shares which shall vest shall be adjusted on a linear basis. For example, if
1998 pre-tax earnings are $500,000, then the number of shares which shall vest
for 1998 is 50,000. While the opportunity for shares to vest shall continue
during the three year period specified, once shares have vested in respect of
the attainment of a given level of annual pre-tax earnings, no additional
vesting shall occur by reason of the attainment of such level of annual pre-tax
earnings during a subsequent year. The maximum aggregate number of shares of
Questron Common Stock issuable under this Section 1.2(a) in respect of all
three years is 100,000. In the event that any shares of Questron Common Stock
do not vest in accordance with the foregoing provisions, then the Sellers shall
return their certificates, evidencing the Questron Common Stock to Questron's
transfer agent for cancellation of the appropriate number of shares.

<PAGE>

         (b) Deferred Purchase Price. The "Deferred Purchase Price" will be
payable in each of the three (3) full calendar years immediately following the
Closing (and pro rata for the partial year from the Closing Date to the end of
1997) as set forth below:

     Company Pre-tax Earnings    % of Pre-tax       Amount
     ------------------------    ------------       ------

    $      0    to   $ 500,000        15%           $75,000
                       
     500,001    to   1,000,000        20%           100,000

   1,000,001    to   1,500,000        25%           125,000
                                      ---           -------
                       Totals         20%          $300,000
                                      ===          ========

The Deferred Purchase Price shall be payable as follows: (1) in respect of the
balance of 1997 and 1998: (A) payment to the Sellers in the proportions set
forth in Schedule 1.1 of an aggregate amount equal to $11,250 payable within
forty-five (45) days after the end of each calendar quarter (a "Quarterly
Payment"); and (B) payment to the Sellers in such proportions on April 15, 1998
and 1999 of the remainder of the Deferred Purchase Price payable in respect of
the preceding years (partial year in the case of 1997); and (2) in respect of
1999 and 2000: (A) payment to the Sellers in the proportions set forth in
Schedule 1.1 of an aggregate amount equal to 60% of the total Deferred Purchase
Price payable in respect of the preceding year divided by four (4) payable
within forty-five (45) days after the end of each calendar quarter (a
"Quarterly Payment"); and (B) payment to the Sellers in such proportions on
April 15, 2000 and 2001 of the remainder of the Deferred Purchase Price payable
in respect of the preceding year. The maximum Deferred Purchase Price payable
in respect of any calendar year is $300,000. In the event that the aggregate
Quarterly Payments made in respect of any year exceed the Deferred Purchase
Price payable in respect of such year, then the Sellers shall repay in the
proportions set forth on Schedule 1.2 such excess on or before April 30 of each
year.

         (c) Calculation of Pre-Tax Earnings. For purposes of this Section 1.2,
pre-tax earnings shall be calculated by Questron on a pro forma basis as
follows: (i) pre-tax earnings of the Company, as reflected on the Company's
income statement, prepared in accordance with generally accepted accounting
principles; plus (ii) an interest charge (equal to Questron's bank borrowing
rate) for the cost of additional capital required by the Company in excess of
its tangible net book value on the Closing Date. On or before April 15 of each
year, Questron shall deliver to the Sellers a statement of pre-tax earnings
together with a review report by Questron's independent public accountants.

         1.3 Restricted Securities. The shares representing the Questron Common
Stock shall be restricted securities under Rule 144 of the Securities Act of
1933, will not have been registered under said act and may not be resold absent
such registration or unless an exception from registration is available, and
the certificates evidencing such shares shall bear an appropriate legend
restricting transfers under said act and evidencing the vesting requirements of
Section 1.2.

<PAGE>

own expenses in connection with this Agreement and its performance. Sellers, on
the one hand, and Questron, on the other hand, each represent and warrant to
the other that the negotiations relative to this Agreement and the transactions
contemplated hereby have been carried on in such a manner as not to give rise
to any valid claims against the other party or the Company for a brokerage
commission, finder's fee or other like payment.

         3.10 Compliance With Law. The operations and activities of the Company
and its subsidiaries have complied and are in compliance in all respects with

Adverse Effect on the Company.

         3.11 Investment Intent. Each of the Sellers is: (a) acquiring the
shares of Questron Common Stock for his own account for investment and not with
a view to any distribution thereof; and (b) has such knowledge and experience
in financial and business affairs that he is capable of evaluating the merits
and risks of acquiring the Questron Common Stock. Each of the Sellers has
heretofore been: (a) furnished with a copy of Questron's Annual Report on Form
10-KSB for the year ended December 31, 1996, any subsequently filed Quarterly
Reports on Form 10-QSB and its Proxy Statement relating to its 1997 Annual
Meeting; and (b) afforded the opportunity to meet with officers of Questron and
ask questions concerning such company.

         3.12 Disclosure. No representations or warranties by Sellers in this
Agreement, including the Exhibits, and no statement contained in any document
(including, without limitation, the financial statements, certificates and
other writings furnished or to be furnished by Sellers to Questron or any of
its representatives pursuant to the provisions hereof or in connection with the
transactions contemplated hereby), contains or will contain any untrue
statement of material fact or omits or will omit to state any material fact
necessary, in light of the circumstances under which it was made, in order to
make the statements herein or therein not misleading. There is no fact known to
the Sellers which has a Material Adverse Effect on the Company which has not
been set forth in this Agreement, including any Exhibit, the Balance Sheet, any
schedule, exhibit, or certificate delivered in accordance with the

                                      -6-
<PAGE>

terms hereof or any document or statement in writing which has been supplied by
or on behalf of Sellers or the Company in connection with the transactions
contemplated by this Agreement.

         3.13 Balance Sheet. The Balance Sheet is complete and correct, was
prepared in accordance with generally accepted accounting principles
consistently applied and fairly presents the financial position of the Company
at such date.

         3.14 PCI Agreement. The representations and warranties of the Company
in the PCI Agreement remain true and correct in all material respects.

                                   ARTICLE 5

           CERTAIN COVENANTS AND AGREEMENTS OF SELLERS AND QUESTRON

         5.1 Tax Covenants. (a) for purposes of this Agreement, "Tax" or
"Taxes" shall mean any federal, state, local, foreign or other taxes
(including, without limitation, income (net or gross), gross receipts, profits,
alternative or add-on minimum, franchise, license, capital, capital stock,
intangible, services, premium, mining, transfer, sales, use, ad valorem,
payroll, wage, severance, employment, occupation, property (real or personal),
windfall profits, import, excise, custom, stamp, withholding or estimated
taxes), fees, duties, assessments, withholdings or governmental charges of any
kind whatsoever (including interest, penalties, additions to tax or additional
amounts with respect to such items) relating to the income, operations or
properties of the Company and its subsidiaries or the ownership thereof (by
Sellers).

         (b) Sellers shall timely cause to be prepared and filed by the Company
all Returns of the Company relating to Pre-Closing Periods and shall timely
pay, or cause to be paid by the Company (at Seller's expense), when due all
Taxes relating to such Returns. Such Returns shall be prepared or completed in
a manner consistent with prior practice of Sellers and the Company with respect
to Returns concerning the income, properties or operations of the Company
(including elections and accounting methods and conventions), except as
otherwise required by law or regulation or otherwise agreed to by Questron
prior to the filing thereof, subject to the proviso of the preceding sentence.

         (c) After the Closing Date, Questron and Sellers shall provide each
other, and Questron shall cause the Company to provide Sellers, with such
cooperation and information relating to the Company as either party reasonably
may request in (A) filing any Tax return, amended return or claim for refund,
(B) determining any Tax liability or a right to refund of Taxes, (C) conducting
or defending any audit or other proceeding in respect of Taxes, or (D)
effectuating the terms of this Agreement. The parties shall retain, and
Questron shall cause the Company to retain, all returns, schedules and work
papers, and all material records and other documents relating thereto, until
the expiration of the statute of limitation (and, to the extent notified by any
party, any extensions thereof) of the taxable years to which such returns and
other documents relate and, unless such returns and other documents are offered
and delivered to Sellers or Questron, as applicable, until the final
determination of any Tax in respect of such years. Any information obtained
under this Section 5.1 shall be kept confidential, except as may be otherwise
necessary in connection with filing any Tax return, amended return, or claim
for refund, determining any Tax liability or right to refund of Taxes, or in
conducting or defending any audit or other proceeding in respect of Taxes.
Notwithstanding the foregoing, neither Sellers nor Questron, nor any of their
affiliates, shall be required unreasonably to prepare any document, or
determine any information not then in its possession, in response to a request
under this Section 5.1(b).

         (d) Sellers shall be liable for, and shall pay when due, (i) any
transfer, gains, documentary, sales, use, registration, stamp, value added or
other similar Taxes payable by reason of the transactions contemplated by this
Agreement or attributable to the sale, transfer or delivery of the Shares
hereunder, and (ii) other Taxes imposed on Sellers or any former shareholder of
the Company for which Questron or the Company is held liable. Other than in the
case of Returns and other

                                      -8-
<PAGE>

documentation that are required to be filed by the Company, which relate to Tax
periods commencing on or after the Closing Date, Sellers shall, at their own
expense, file all necessary Tax returns and other documentation with respect to
all such Taxes.

         5.2 No Solicitation. Sellers shall not, and shall direct the Company
and its affiliates, officers, employees, representatives or agents not to,
directly or indirectly, encourage, solicit, initiate or engage in discussions
or negotiations with, or provide any non-public information to, any Person
concerning any merger, sales of substantial assets, sales of shares of capital
stock or similar transactions involving the Company or enter into any agreement
with respect thereto. Sellers will promptly communicate to Questron the terms
of any proposal which it may receive in respect of all such transactions
prohibited by the foregoing.


         5.3 Press Releases. Except as required by law or stock exchange
regulation, any public announcements by the Company or the Sellers regarding
the transactions contemplated hereby shall be made only with the consent of
Questron.

         5.4 Transitional Assistance. Sellers shall reasonably cooperate with
and assist Questron in the orderly transfer of the business of the Company
after the Closing Date. Such cooperation and assistance shall include, but not
be limited to, the physical transfer of any books, records and computer
software of the Company.

         5.5 PCI Transaction. The transactions contemplated by the PCI
Agreement shall have been consummated simultaneously with the Closing and none
of the conditions under the PCI Agreement shall have been waived by the Sellers
or the Company.


                                   ARTICLE 6

                                INDEMNIFICATION

         6.1 Indemnification by Sellers. Effective only from and upon the
occurrence of the Closing, and subject to Section 6.3 below, each of the
Sellers hereby agrees to jointly and severally defend, indemnify and hold
harmless Questron and the Company and their respective successors, assigns and
affiliates (collectively, the "Questron Indemnitees") from and against any and
all losses, deficiencies, liabilities, damages, assessments, judgments, costs
and expenses, including reasonable attorneys' fees (both those incurred in
connection with the defense or prosecution of the indemnifiable claim and those
incurred in connection with the enforcement of this provision), including,
without limitation, Environmental Liabilities and Costs (collectively,
"Questron Losses"), caused by, resulting from or arising out of:

              (a) (i) breaches of representation or warranty under this
    Agreement on the part of any Seller; and (ii) failures by any of the
    Sellers to perform or otherwise fulfill any undertaking or other agreement
    or obligation under this Agreement;

              (b) any and all Taxes imposed on the Company (including, without
    limitation, Taxes relating to the Tax liability of Sellers to the extent
    any governmental authority seeks to impose such Taxes on the Company) for,
    or relating to, all Pre-Closing Periods to the extent the

                                      -9-
<PAGE>

    charges, accruals and reserves therefor as reflected on the books
    of the Company as of the date of the Closing are inadequate to cover such
    Taxes; and

              (c) any and all actions, suits, proceedings, claims, demands,
    incident to any of the foregoing or such indemnification;

provided, however, that if any claim, liability, demand, assessment, action,
suit or proceeding shall be asserted in respect of which a Questron Indemnitee
proposes to demand indemnification ("Questron Indemnified Claims"), Questron or
such other Questron Indemnitee shall promptly notify the Sellers thereof,
provided further, however, that the failure to so notify the Sellers shall not
reduce or affect Sellers' obligations with respect thereto except to the extent
that Sellers are materially prejudiced thereby. Subject to rights of or duties
to any insurer or other third Person having liability therefor, the Sellers
shall have the right promptly upon receipt of such notice (after acknowledging
responsibility for such Questron Indemnified Claim) to assume the control of
the defense, compromise or settlement of any such Questron Indemnified Claims
(provided that any compromise or settlement must be reasonably approved by
Questron), including, at its own expense, employment of counsel reasonably
satisfactory to Questron; provided, however, that if the Sellers shall have
exercised their right to assume such control, Questron may, in its sole
discretion and at its expense, employ counsel to represent it (in addition to
counsel employed by the Sellers) in any such matter. So long as the Sellers are
contesting any such Questron Indemnified Claim in good faith, Questron and each
other Questron Indemnitee shall not pay or settle any such Questron Indemnified
Claim. Notwithstanding the foregoing, Questron shall have the right to offset
any Questron Indemnified Claims and/or Questron Losses against the Deferred
Purchase Price.

         6.2 Indemnification by Questron. Questron hereby agrees to defend,
indemnify and hold harmless Sellers and their respective successors, assigns
and affiliates (collectively, "Seller Indemnitees") from and against any and
all losses, deficiencies, liabilities, damages, assessments, judgments, costs
and expenses, including reasonable attorneys' fees (both those incurred in
connection with the defense or prosecution of the indemnifiable claim and those
incurred in connection with the enforcement of this provision) (collectively,
"Seller Losses"), resulting from or arising out of:

              (a) (i) breaches of representation and warranty hereunder on the
    part of Questron, and (ii) failures by Questron to perform or otherwise
    fulfill any undertaking or agreement or obligation hereunder; and

              (b) any and all actions, suits, proceedings, claims and demands
    incident to any of the foregoing or such indemnification;

provided, however, that if any claim, liability,  demand, assessment,  action,
suit or proceeding  shall be asserted in respect of which a Seller  Indemnitee
proposes to demand  indemnification  ("Seller Indemnified Claims"),  Seller or
such other Seller Indemnitee shall notify Questron thereof,  provided further,
however,  that the  failure to so notify  Questron  shall not reduce or affect
Questron's  obligations  with  respect  thereto  except  to  the  extent  that
Questron is materially  prejudiced thereby.  Subject to rights of or duties to
any insurer or other third Person having  liability  therefor,  Questron shall
have the right  promptly  upon receipt of such notice to assume the control of
the defense,  compromise or settlement of any such Seller  Indemnified  Claims
(provided  that any  compromise or settlement  must be reasonably  approved by
Seller)  including,  at its own  expense,  employment  of  counsel  reasonably
satisfactory  to  Seller;  provided,  however,  that if  Questron  shall  have
exercised  its  right  to  assume  such  control,  Seller

                                     -10-
<PAGE>

may, in its sole discretion and at its expense, employ counsel to represent it
(in addition to counsel employed by Questron) in any such matter. So long as
Questron is contesting any such Seller Indemnified Claim in good faith, Seller
or such other Seller Indemnitees shall not pay or settle any such Seller
Indemnified Claim.

         6.3 Limitation on Liability. The aggregate liability of the Sellers
under this Article 6 shall not exceed the aggregate amount of consideration
received by the Sellers as Initial Purchase Price and Deferred Purchase Price.


                                   ARTICLE 7

             SURVIVAL OF REPRESENTATIONS, WARRANTIES AND COVENANTS

         7.1 Representations, Warranties and Covenants. The covenants contained
in this Agreement shall survive the Closing Date without limitation. The
representations and warranties contained herein shall survive the Closing Date
for a period of three (3) years, except that any representation or warranty of
Sellers contained in Sections 3.1, 3.5 and 3.6 shall survive the Closing Date
without limitation.


                                   ARTICLE 8

                 NON-COMPETITION BY SELLERS AND NO SOLICITATION

         8.1 Non-Compete; Non-Solicitation. In consideration of the purchase by
Questron of the Shares under this Agreement, the Sellers will at the Closing
execute and deliver non-compete agreements in the form attached to the
Employment Agreements.

         8.2 Remedies. Each Seller recognizes that a breach or threatened
breach by him of his obligations under this Article 8 and the Employment
Agreements would cause irreparable injury to the Company, and the Company shall
be entitled to seek preliminary and permanent injunctions enjoining him from
violating the non-compete agreements contemplated by this Article 8, in
addition to any other remedies which may be available.


                                   ARTICLE 9

to comply with any of its obligations or agreements herein contained may be
