Dotronix, Inc.

160 First Street SE

New Brighton, MN 55112-7894 




Dear Ladies and Gentlemen: 



        The
undersigned ("Lender") hereby agrees to amend the Loan Agreement dated April 7, 2004 (the
"Original Loan Agreement") between the undersigned and Dotronix, Inc. ("Borrower") as set
forth below.  Capitalized terms shall have the meanings provided to them in the Original
Loan Agreement unless defined otherwise in this Agreement. 



        1.      Lender hereby agrees to lend to Borrower a principal amount of up to $1,000,000
until November 1, 2005.  The first sentence in the paragraph entitled "The Loan" in the
Original Loan Agreement is hereby replaced with the following language: 



        "Subject
to the terms and conditions of this Agreement, Lender will make loans to the Borrower
(collectively, the "Loan") from time to time from the date hereof until November 1, 2005,
during which period the Borrower may repay and reborrow in accordance with the provisions
hereof, provided, that the aggregate unpaid principal amount of all outstanding loans
under this Agreement shall not exceed $1,000,000 at any time." 



        The
remainder of the Original Loan Agreement is hereby amended to the extent necessary so as
to reflect the increase of the maximum principal amount from $450,000 to $1,000,000, and
the extension of the payment period from April 7, 2005 to November 1, 2005. 



        The
remaining terms and conditions of the Original Loan Agreement remain in full force and
effect. 




        2.      Lender herewith returns to Borrower the Note evidencing the original Loan of up to
$450,000, payable on or before April 7, 2004 (the "Old Note").  Upon the return of the
Old Note and the receipt of this Agreement signed by Lender, Borrower shall issue to
Lender a new note (the "New Note") for a principal amount of up to $1,000,000, payable on
or before November 1, 2005.  With the exception of the maximum principal amount of
$1,000,000 and the expiration date of November 1, 2005, all terms and conditions of the
New Note shall be identical with the terms of the Old Note. 



        3.      In consideration of Lender's agreement to increase and extend the Loan, Borrower
agrees to issue to Lender one seven-year warrant in a form acceptable to Lender to












purchase one share of the Borrower's
common stock at an exercise price of $1.50 for each $4 of the principal amount in excess
of $450,000 that Lender actually advances to Borrower (the "Additional Warrant").  The
Additional Warrant shall be issued promptly each time upon Borrower's receipt of an
advance on the Loan if the outstanding principal amount under the Loan exceeds $450,000.
