                            CONSENT TO MODIFICATIONS

         This Consent to Modifications, dated March 17, 2003, is given and
agreed to by the "Purchasers" under the Second Amended Note and Warrant Purchase
Agreement by and among the Purchasers, Integral Vision, Inc., a Michigan
corporation (the "Company"), and Warren Cameron Faust & Asciutto, P.C., as
Agent.

                               Factual Statements

A.       The undersigned is a Purchaser under the Second Amended Note and
         Warrant Purchase Agreement, dated effective as of the date of execution
         by such Purchaser, for the purchase of the Notes and Warrants of the
         Company (the "Purchase Agreement").

B.       The parties to this Purchase Agreement wish to modify certain portions
         of the Purchase Agreement, which shall be accomplished by attaching
         said changes to the Purchase Agreement in the form of an addendum to
         the Purchase Agreement. One of the modifications desired by the parties
         to the Purchase Agreement is to increase the amount of notes authorized
         under said Purchase Agreement from the present limit of $2,000,000 to
         $2,500,000 and to clarify that the limit applies to the amount of notes
         outstanding at any time rather than to the amount issued.

C.       The Company is indebted to Purchasers of Class 1 Notes numbered 1
         through 20 pursuant to the terms of the Promissory Notes (the "Class 1
         Notes") purchased by the Purchasers pursuant to the Purchase Agreement
         which provides for quarterly interest payments and quarterly principal
         payments. None of the required interest and principal payments have
         been paid to such Purchasers. The parties now wish to postpone the
         payment of all interest due Purchasers of Class 1 Notes until December
         31, 2003, to postpone the requirement that the Company commence
         principal payments as specified under said Class 1 Notes until March
         31, 2004, and to extend the maturity date for said Class 1 Notes until
         February 27, 2007.

D.       The Company is also indebted to the Purchasers of Class 2 Notes
         numbered 8 through 16 (the "Class 2 Notes") purchased by the Purchasers
         pursuant to the Purchase Agreement and subsequent amendments to some of
         the Class 2 Notes. The parties now wish to further amend said notes to
         extend the maturity date of the Class 2 Notes from the current March
         31, 2003 maturity date to September 30, 2003.

                                    Agreement

1.       Modifications. The undersigned agree to the modifications to the
         Purchase Agreement as follows:

         SECTION 1.A.: The reference to "Section 2(c)" in the last sentence of
         this section shall be corrected to refer to "Section 2(d)."

         SECTION 1.B.: In the portion of said section stating, "As used herein,
         "Notes" means either "Class 1 Notes" or "Class 2 Notes" in a total
         aggregate amount not to exceed $2,000,000" shall be modified to read,
         "As used herein, "Notes" means either "Class 1 Notes" or "Class 2
         Notes" in a total aggregate amount outstanding at any time not to
         exceed $2,500,000."

<PAGE>



         SECTION 1.(B)(I): In the portion of said section stating, "Class 1
         Notes issued after April 15, 2002 will be subordinated to the Class 1
         Notes issued on or before April 15, 2001 in their rights to receive
         payment under the Collateral Assignment, as defined below" shall be
         corrected to read, "Class 1 Notes issued after April 15, 2002 will be
         subordinated to the Class 1 Notes issued on or before April 15, 2002 in
         their rights to receive payment under the Collateral Assignment, as
         defined below."

         SECTION 2.D. shall be amended by adding the following to said section:
         "For all notes and warrants issued under this Purchase Agreement after
         December 31, 2001 the Company and its tax advisors have determined that
         the limited marketability of the Company's common shares does not
         provide a reasonable basis for the Company and its advisors to
         determine a value for the warrants issued. Therefore, all warrants
         issued by the company pursuant the Purchase Agreement after December
         31, 2001 shall have only a minimal or negligible value ascribed to
         them."

         SECTION 11.1. shall be modified by adding the following to said
         section: "or (v) modify the subordination terms in the Purchase
         Agreement, including without limitation, the subordination terms in
         Sections 1.(b) (i), 1. (b) (ii), 6.1. (c), and 20.2. without the
         consent of the holder of each Note so affected."

2.       Modifications to Class 1 Notes, Class 2 Notes, and Warrants and
         additional agreements to implement sections C and D above.

         CLASS 1 NOTES. The undersigned holders of Class 1 Notes hereby agree to
         the postponement of all interest payments due Purchasers of Class 1
         Notes until December 31, 2003, to the postponement of the requirement
         that the Company commence principal payments as specified under said
         Class 1 Notes until March 31, 2004, and to extend the maturity date for
         said Class 1 Notes until February 27, 2007.

         CLASS 2 NOTES. The undersigned holders of Class 2 Notes hereby agree to
         extend the maturity date for said Class 2 Notes from March 31, 2003 to
         September 30, 2003.

         UNANIMOUS APPROVAL. These above modifications to Class 1 Notes and
         Class 2 Notes require the unanimous consent of all holders of Class 1
         Notes and Class 2 Notes specified in sections C and D above.

         CONSIDERATION. All of the parties to this CONSENT TO MODIFICATIONS
         agree that the consideration for the holders of Class 1 Notes and Class
         2 Notes specified in sections C and D to consent to the modifications
         in this section shall be as follows:

         a.       At the time each of the Class 1 Notes was purchased by the
                  Purchaser, the Company issued to each Purchaser Common Stock
                  Purchase Warrant Certificates ("Warrants"). The date specified
                  in said Warrants for their exercise shall be extended from the
                  fourth anniversary of the date said Warrants were issued to
                  February 27, 2007. Additionally, the purchase price per share
                  specified in said Warrants shall be reduced from whatever
                  price was originally specified to $0.25 per share.

         b.       At the time each of the Class 2 Notes was purchased by the
                  Purchaser, the Company agreed to issue to each Purchaser
                  Warrants with an exercise price of $0.35 per share. This $0.35
                  per share


<PAGE>


                  exercise price shall be reduced to $0.25 per share, which is
                  acknowledged to be at or above the market price for the
                  Company's common stock at the date of this Agreement.

         c.       In addition the Company agrees that it will require that all
                  new Class 1 Notes issued by the Company after March 17, 2003
                  ("New Notes") shall include an agreement from each New Note
                  holder to defer all interest payments due each New Note holder
                  until December 31, 2003.

         d.       The Company agrees to issue each Class 1 Note holder, Class 2
                  Note holder, and Warrant holder an addendum duly endorsed by
                  an authorized officer of the Company to attach to each said
                  note or warrant incorporating the changes agreed to herein.

3.       Voluntary and Informed Execution. THE PARTIES ACKNOWLEDGE THAT THEY
         HAVE HAD AN OPPORTUNITY TO CONSULT WITH LEGAL COUNSEL WITH RESPECT TO
         THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY, AND THAT THE
         MODIFICATIONS SET FORTH HEREIN WERE KNOWINGLY AND VOLUNTARILY MADE.

4.       Effective Date. This agreement shall be effective on the date all
         parties to this Consent to Modification, including the Company and
         Agent, have signed this agreement (or counter part thereto) and the
         Board of Directors of the Company has accepted the terms and conditions
         herein if, and only if, all of the aforementioned parties sign this
         agreement and the Board of Directors of the Company accepts these terms
         and conditions on or before March 31, 2003.

5.       Remaining Terms Unaffected. Except as set forth in this Consent to
         Modifications, the terms of the Purchase Agreement shall continue in
         full force and effect.
