                             FOURTH AMENDMENT TO THE
                     PERCEPTRON, INC. 1992 STOCK OPTION PLAN
                     (AMENDED AND RESTATED OCTOBER 31, 1996)

         Pursuant to the Amendment provisions in Section 9.2 of the Perceptron,
Inc. 1992 Stock Option Plan ("Plan") and the approval of the Board of Directors
of Perceptron, Inc. ("Company"), the Plan is hereby amended as set forth below.

         1. Subject to shareholder approval, Section 4.1 of the Plan (Shares
Available for Options) shall be amended and restated in its entirety to read as
follows:

                  4.1 SHARES AVAILABLE FOR OPTIONS. The Board of Directors shall
         reserve for purposes of this Plan, out of the authorized but unissued
         Stock or out of shares of Stock held in the Company's Treasury, or
         partly out of each, a total of 2,814,286 shares of Stock, after taking
         into account the Company's reverse stock split effected on May 5, 1992
         and stock split effected November 30, 1995, (or the number and kind of
         shares of Stock or other securities which, in accordance with Section 8
         of this Plan, shall be substituted for such shares or to which such
         shares shall be adjusted).

         2. Section 6.1 of the Plan (Termination of Employment - General) shall
be amended and restated in its entirety to read as follows:

                  6.1 GENERAL. If the employment by the Company of any optionee
         who is an Employee shall terminate for any reason, other than by death
         or total and permanent disability, any option which such optionee is
         entitled to exercise on the date of such termination shall be
         exercisable by the optionee at any time on or before the earlier of the
         expiration date of the option or three months after the date of such
         termination, but only to the extent of the accrued right to purchase at
         the date of such termination. Notwithstanding the foregoing, the
         Committee, in its discretion, may extend an exercise period, not to
         exceed the tenth anniversary of the date of the grant, and may permit
         the option to continue to accrue rights to purchase additional shares
         of Stock following any termination of employment of any option; it
         being understood, that the extension of the exercise term or accrual
         right as set forth above for an Incentive Stock Option may cause such
         Option to lose its preferential tax treatment.

         THIS FOURTH AMENDMENT is hereby adopted as of August 16, 2002.

                            PERCEPTRON, INC.

                               EXCHANGE AGREEMENT

         EXCHANGE AGREEMENT (the "Agreement"), dated as of __________, 2002,

Edward W. Stack, Martin J. Stack, Stacey A. Stack, Donna Stack, Kim Myers, Nancy

collectively, the "Holders");

                                   WITNESSETH

         WHEREAS, each Holder is currently a holder of common stock, par value
$.01 per share, of the Company (the "Common Stock");

         WHEREAS, pursuant to the initial public offering of the Company's
common stock (the "IPO"), the Company has amended and restated its Certificate
of Incorporation, in the form attached hereto as EXHIBIT A (the "Restated
Certificate") to, among other things, create a new Class B common stock, par
value $.01 per share, (the "Class B Common Stock");

         WHEREAS, the Class B Common Stock shall have those rights, preferences
and privileges as set forth in the Restated Certificate; and

         WHEREAS, in connection with the IPO, the Company and the Holders desire
to exchange that number of outstanding shares of Common Stock set forth opposite
such Holders name on EXHIBIT B attached hereto (the "Old Shares") for an equal
number of shares of Class B Common Stock, again as set forth on EXHIBIT B
attached hereto (the "New Shares"), upon the terms and subject to the conditions
of this Agreement;

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
herein set forth and each act done pursuant hereto, the parties hereto,
intending to be legally bound, do hereby represent, warrant, covenant and agree
as follows:

         1. EXCHANGE.

         1.1 EXCHANGE OF COMMON STOCK. Each Holder hereby agrees to assign and
transfer to the Company at the Closing (as defined below), and the Company
hereby agrees to acquire and accept from each Holder all right, title and
interest in and to that number of Old Shares set forth opposite such Holder's
name on EXHIBIT B in consideration for the issuance and transfer by the Company
to such Holder of that number of New Shares set forth opposite such Holder's
name on EXHIBIT B (such number of shares to be adjusted for any stock split,
dividend or similar event).

         1.2. CLOSING AND DELIVERIES. The exchange provided for in Section 1.1
hereof shall take place at the offices of the Company at 10:00 a.m. (Pittsburgh,
PA local time) on the date immediately prior to the consummation of the IPO (the
"Closing"). At the Closing or as soon thereafter as reasonably practicable, the
Company shall duly and validly deliver to each Holder a stock certificate
representing the New Shares acquired by such Holder.

<PAGE>

         2. REPRESENTATIONS AND WARRANTIES OF THE HOLDERS.

         (a) Each Holder hereby represents and warrants, as to himself or
herself, but not as to any other Holder, that he/she owns all right, title and
interest to the Old Shares set opposite his/her name on EXHIBIT B free and clear
of any claim, suit, proceeding, call, commitment, trust, proxy, restriction,
limitation, security interest, pledge or lien or encumbrance of any kind or
nature whatsoever, and has full power and authority to transfer and assign the
same hereunder to the Company.

         (b) Each Holder represents, as to himself or herself, but not as to any
other Holder, that the New Shares to be received by it hereunder will be
acquired for investment for its own account, not as a nominee or agent, and not
with a view to the sale or other transfer of any part thereof or interest
therein, and that it has no present intention of selling or otherwise
transferring the New Shares with the exception of shares of Common Stock being
sold by the Holders in connection with the IPO, but subject nevertheless to any
requirement of law that the disposition of its property shall at all times be
within its control.

         (c) Each Holder understands that the New Shares to be received by it
hereunder are not registered under the Securities Act of 1933, as amended (the
"Securities Act"), on the ground that the exchange provided for in this
Agreement and the issuance of the New Shares are exempt from registration
pursuant to Section 3(a)(9) of the Securities Act.

         3. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         (a) The Company hereby represents and warrants that the New Shares
being issued to the Holders hereunder, when issued, transferred and delivered in
accordance with the terms hereof for the consideration expressed herein, will be
duly and validly issued, fully paid and nonassessable, free of restrictions of
transfer other than pursuant to the terms thereof, applicable state and federal
securities laws, those restrictions set forth in the Restated Certificate and
other contractual restrictions entered into by such Holders.

         (b) The Company is a corporation duly organized, validly existing and
in good standing under the laws of the State of Delaware, has all requisite
corporate power and authority to own its properties and assets, to carry on its
business as now conducted and as proposed to be conducted and to execute,
deliver and perform this Agreement.

         (c) All corporate action on the part of the Company and its officers,
directors and stockholders necessary for the authorization, execution, delivery
and performance of all obligations of the Company under this Agreement and for
the authorization, issuance and delivery of the New Shares being exchanged under
this Agreement has been taken or will be taken prior to the Closing. This
Agreement, when executed and delivered, shall constitute a valid and legally
binding obligation of the Company, enforceable in accordance with its terms.

         5. LEGENDS. Each Holder acknowledges as follows:

         (a) The New Shares must bear legends substantially similar to the
following legends:
