                             OPTION POOL AGREEMENT

     THIS OPTION POOL AGREEMENT (this "AGREEMENT") is entered into effective
December 21, 2001 (the "EFFECTIVE DATE") by and between Industrial Data Systems
Corporation, a Nevada corporation (together with its existing and future
subsidiaries, "IDS" or the "COMPANY"), and Alliance 2000, Ltd., a Texas limited
partnership ("ALLIANCE").

                                    RECITALS

     Alliance and IDS desire to provide an incentive for key employees of IDS to
remain in the service of IDS, to extend to them the opportunity to acquire a
proprietary interest in IDS so that they will apply their best efforts for the
benefit of IDS, and to aid IDS in attracting able persons to enter the service
of IDS;

     Alliance has agreed, in accordance with the terms of that certain Agreement
and Plan of Merger dated July 31, 2001, to give certain employees of Petrocon
and certain current and future employees of IDS an option to acquire up to
2,600,000 shares of the common stock, par value $.001 per share (the "COMMON
STOCK"), of IDS held by Alliance in accordance with the terms of this Agreement;

     NOW, THEREFORE, the parties agree as follows:

     1.  Option Pool.  Alliance hereby agrees to hold 2,600,000 shares of Common
Stock, (the "OPTION SHARES") and to grant options (the "ALLIANCE OPTIONS") to
acquire the Option Shares, in such amounts and to such persons as are determined
from time to time from the Effective Date until the Termination Date (as defined
below) by the mutual agreement of the General Partner of Alliance and the
Shareholder Representative of the Significant PEI Shareholders as those terms
are defined in that certain Voting Agreement dated of even date herewith by and
between the Significant PEI Shareholders and Michael L. Burrow in his capacity
as the Shareholder Representative.  If any of the options granted pursuant to
this Agreement lapse prior to their exercise, then the General Partner of
Alliance and the Shareholder Representative shall determine, by mutual
agreement, the persons and the amounts in which further options shall be
granted; provided however, at no time shall the Alliance Options (including any
Alliance Options which have been exercised) exceed the right to acquire
2,600,000 shares of Common Stock.  This Agreement shall terminate on December
21, 2006 (the "TERMINATION DATE").

     2.  Option Agreements.  The options shall be granted pursuant to option
agreements in the form of the agreement set forth on Exhibit A and no changes
may be made in the form or substance of the Option Agreements without the prior
written consent of Alliance and the Company.

     3.  Reclassification.  If IDS at any time shall, by subdivision,
combination or reclassification of securities or otherwise, change any of the
securities covered by the Option Pool into the same or a different number of
securities of any class or classes, or a dividend or other distribution is
issued with respect to the Option Shares, this Agreement shall thereafter
represent a right to grant options with respect to such number and kind of
securities and the dividend or other distribution as were issued as the result
of such change.

at least the number of shares for which options have been granted or may be
granted hereunder, and that it shall not sell or transfer shares of Common Stock
