                               AMENDMENT NO. 1 TO
            AGREEMENT TO EXTEND AND AMEND LOAN AND SECURITY AGREEMENT

This Amendment No. 1 (the "Amendment") is entered into this 7th day of April
2004 by and between the Estate of William S. Sadler, 1370 West Ryan Avenue,
Roseville, MN 55113 (the "Estate") and Dotronix, Inc., a Minnesota corporation,
with its principal place of business located at 160 First Street S.E., St. Paul
Minnesota 55112-7894 ("Dotronix"), to amend that Agreement to Extend and Amend
Loan and Security Agreement dated November 5, 2003 (the "Agreement") between the
Estate and Dotronix.

WHEREAS, the Agreement provided for the transfer of certain real property of
Dotronix to the Estate; and

WHEREAS, in the meantime the parties have agreed that such real property shall
be sold to a third party instead of being transferred to the Estate and that the
proceeds from such sale shall be paid to the Estate;

NOW, THEREFORE, in consideration of the premises and the mutual covenants
contained in this Amendment, the parties hereto agree as follows:

1.   Section 1 of the Agreement is deleted and replaced with the following

     $465,000.00 from such sale, less $17,132.68 for fees and expenses payable
     upon the closing of the sale (the "Sales Proceeds") to the Estate. Such
     payment shall be made upon the closing of the sale of the real estate. Upon
     payment of the Sales Proceeds to the Estate, the principal amount due and
     owing under the Loan and Security Agreement dated February 23, 2000 (the
     "Loan Agreement"), as amended, originally entered into by and between
     William S. Sadler and Dotronix, shall be reduced from $1,000,000 to
     $150,000."

                                       18EXHIBIT 10.4

         THIS WARRANT AND THE SECURITIES REPRESENTED HEREBY AND ISSUABLE
PURSUANT HERETO HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "SECURITIES ACT") AND MAY NOT BE OFFERED OR SOLD, TRANSFERRED,
PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT IN A TRANSACTION THAT IS
EXEMPT FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND FROM THE
REGISTRATION AND QUALIFICATION REQUIREMENTS OF APPLICABLE STATE SECURITIES LAWS,
OR IN A TRANSACTION EFFECTED PURSUANT TO SUCH REGISTRATION AND QUALIFICATION.

         THIS WARRANT IS NOT TRANSFERABLE EXCEPT AS SET FORTH IN PARAGRAPH 7
BELOW.

                                 DOTRONIX, INC.
                            (A MINNESOTA CORPORATION)

                       WARRANT TO PURCHASE 385,000 SHARES
                   OF COMMON STOCK, PAR VALUE $0.05 PER SHARE

         THIS CERTIFIES THAT, for value received, Estate of William S. Sadler or
its permitted transferees (the "Holder") is entitled to subscribe for and
purchase 385,000 shares (the "Shares") of fully paid and nonassessable common
stock, par value $0.05 per share ("Common Stock") of Dotronix, Inc., a Minnesota
corporation (the "Company") at the Warrant Exercise Price as determined in
accordance with the terms hereof, which shall initially be equal to $0.05 per
share, subject to the provisions and upon the terms and conditions hereinafter
set forth.

         1. Term. The purchase right represented by this Warrant is exercisable,
in whole or in part, at any time and from time to time commencing on the date
hereof and ending at the close of business on April 7, 2011.

         2. Method of Exercise; Payment; Issuance of New Warrant. Subject to
Paragraph 1 hereof, the purchase right represented by this Warrant may be
exercised by the Holder, in whole or in part and from time to time, by the
surrender of this Warrant (with the notice of exercise form attached hereto as
Exhibit 1 duly executed) at the principal office of the Company and by the
payment to the Company, by check or such other manner of payment as the parties
may agree, of an amount equal to the then applicable Warrant Exercise Price (as
defined in Paragraph 4) per share multiplied times the number of Shares then
being purchased. The person or persons in whose name(s) any certificate(s)
representing the Shares shall be issuable upon exercise of this Warrant shall be
deemed to have become the holder(s) of record of, and shall be treated for all
purposes as the record holder(s) of, the shares represented thereby (and such
shares shall be deemed to have been issued) immediately prior to the close of
business on the date or dates upon which this Warrant is exercised. In the event
of any exercise of the rights represented by this Warrant, certificates for the
shares of stock so purchased shall be delivered

                                       19
<PAGE>

to the Holder as soon as is reasonably practicable and, unless this Warrant has
been fully exercised or expired, a new Warrant representing the portion of the
Shares, if any, with respect to which this Warrant shall not then have been
exercised shall also be issued to the Holder as soon as is reasonably
practicable.

         3. Stock Fully Paid; Reservation of Shares. The Company agrees that all
Shares issued upon the exercise of the rights represented by this Warrant will,
upon issuance, be fully paid and nonassessable, and free from all preemptive
rights, taxes, liens and charges with respect to the issue thereof; provided,
that the Company shall not be required to pay any withholding taxes with respect
to the issue of shares or any transfer taxes with respect to the issue of shares
in any name other than that of the registered holder hereof. During the period
within which the rights represented by this Warrant may be exercised, the
Company will at all times have authorized, and reserved for the purpose of
issuance upon exercise of the purchase rights evidenced by this Warrant, a
sufficient number of shares of its Common Stock to provide for the exercise of
the rights represented by this Warrant. The Company shall at all times take all
such action and obtain all such permits or orders as may be necessary to enable
the Company lawfully to issue such shares of Common Stock as duly and validly
issued, fully paid and nonassessable shares upon exercise in full of this
Warrant by Holder.

         4. Adjustment of Warrant Exercise Price and Number of Shares. The
number and kind of securities purchasable upon the exercise of this Warrant and
the Warrant Exercise Price shall be subject to adjustment from time to time upon
the occurrence of certain events as set forth in this Paragraph 4:

                  (a) If the Company at any time divides the outstanding shares
         of its Common Stock into a greater number of shares (whether pursuant
         to a stock split, stock dividend or otherwise), and conversely, if the
         outstanding shares of its Common Stock are combined into a smaller
         number of shares, the Warrant Exercise Price in effect immediately
         prior to such division or combination shall be proportionately adjusted
         to reflect the reduction or increase in the value of each such share of
         Common Stock.

                  (b) If any capital reorganization or reclassification of the
         capital stock of the Company, or consolidation or merger of the Company
         with another corporation, or the sale of all or substantially all of
         its assets to another corporation shall be effected in such a way that
         holders of the Company's Common Stock shall be entitled to receive
         stock, securities or assets with respect to or in exchange for such
         Common Stock, then, as a condition of such reorganization,
         reclassification, consolidation, merger or sale, the Holder shall
         thereafter have the right to purchase and receive upon the basis and
         upon the terms and conditions specified in this warrant and in lieu of
         the shares of the Common Stock of the Company immediately theretofore
         purchasable and receivable upon the exercise of the rights represented
         hereby, such shares of stock, other securities or assets as would have
         been issued or delivered to the Holder if Holder had exercised this
         Warrant and had received such shares of Common Stock immediately prior
         to such reorganization, reclassification, consolidation, merger or
         sale. The Company shall not effect any such consolidation, merger or
         sale unless prior to the consummation thereof the successor corporation
         (if other than the Company) resulting from such consolidation or merger
         or the corporation purchasing such assets shall assume by written
         instrument executed and mailed to the Holder at the last address of the
         Holder appearing on the books of the Company the obligation to deliver
         to the Holder such shares of stock,

                                       20
<PAGE>

         securities or assets as, in accordance with the foregoing provisions,
         the Holder may be entitled to purchase.

                  (c) Except as provided in paragraph (d) below, if and whenever
         the Company shall (i) issue or sell any shares of Common Stock for a
         consideration per share less than the Warrant Exercise Price in effect
         immediately prior to the time of such issuance or sale, (ii) issue or
         sell any warrants, options or other rights to acquire shares of Common
         Stock at a purchase price less than the Warrant Exercise Price in
         effect immediately prior to the time of such issuance or sale, or (iii)
         issue or sell any other securities that are convertible into shares of
         Common Stock for a purchase or exchange price less than the Warrant
         Exercise Price in effect immediately prior to the time of such issuance
         or sale, then, upon such issuance or sale, the Warrant Exercise Price
         shall be reduced to the price (calculated to the nearest cent)
         determined by dividing (A) an amount equal to the sum of (I) the number
         of shares of Common Stock outstanding immediately prior to such issue
         or sale multiplied by the then existing Warrant Exercise Price and (II)
         the consideration, if any, received by the Company upon such issue or
         sale plus the consideration to be received by the Company upon the
         exercise of such stock purchase rights by (B) an amount equal to the
         sum of (I) the number of shares of Common Stock outstanding immediately
         prior to such issue or sale and (II) the number of shares of Common
         Stock thus issued or sold or issuable or saleable upon the exercise of
         such purchase rights or the conversion of such convertible securities;
         PROVIDED, HOWEVER, that in the event that any such purchase right
         expires or is terminated prior to the exercise of this Warrant, the
         Warrant Exercise Price shall be recalculated by deleting such purchase
         right, and PROVIDED FURTHER, that if an adjustment is made to the
         Warrant Exercise Price as a result of the issuance or sale of any such
         purchase rights or convertible securities, no further adjustment shall
         be made to the Warrant Exercise Price at the time such purchase rights
         are exercised or convertible securities are converted.

                  (d) Notwithstanding the provisions of paragraph (c) above, no
         adjustment shall be made in the Warrant Exercise Price as a result of
         (i) the exercise of options or warrants to purchase Common Stock or
         other derivative securities exercisable for shares of Common Stock
         which are outstanding at the date of this Warrant; (ii) the grant of
         options to purchase Common Stock or the grant of restricted stock and
         other similar equity-based compensation awards pursuant to stock option
         and incentive plans which have been or are in the future approved by
         the Company's board of directors, or the exercise of such options or
         awards or (iii) the issuance of additional warrants in substantially
         the form of this Warrant pursuant to the Company's borrowing
         arrangements with Terry L. Myhre, or the exercise of such warrants.

                  (e) If the Company takes any other action, or if any other
         event occurs, which does not come within the scope of the provisions of
         paragraphs (a) through (c) above but which should result in an
         adjustment in the Warrant Exercise Price and/or the number of shares
         subject to this Warrant in order to fairly protect the purchase rights
         of the Holder, an appropriate adjustment in such purchase rights shall
         be made by the Company.

                  (f) Upon each adjustment of the Warrant Exercise Price, the
         Holder shall thereafter be entitled to purchase, at the Warrant
         Exercise Price resulting from such adjustment, the number of shares
         obtained by multiplying the Warrant Exercise Price in

                                       21
<PAGE>

         effect immediately prior to such adjustment by the number of shares
         purchasable pursuant hereto immediately prior to such adjustment and
         dividing the product thereof by the Warrant Exercise Price resulting
         from such adjustment.

                  (g) Upon any adjustment of the warrant exercise price, the
         Company shall give written notice thereof to the Holder stating the
         warrant exercise price resulting from such adjustment and the increase
         or decrease, if any, in the number of shares purchasable at such price
         upon the exercise of this warrant, setting forth in reasonable detail
         the method of calculation and the facts upon which such calculation is
         based.

         5. No Fractional Shares. No fractional shares of Common Stock will be
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor upon the basis of the
market price of such shares as of the close of business on the exercise date.

         6. No Privilege of Stock Ownership. Prior to the exercise of this
Warrant, the Holder shall not be entitled, by virtue of holding this Warrant, to
any rights of a stockholder of the Company, including (without limitation) the
right to vote or to receive dividends or other distributions.

         7. Transfer of Warrant. This Warrant shall not be transferable except
pursuant to the laws of descent and distribution.

         8. No Registration Rights; Legend. The Company is not obligated to
register this Warrant or any of the shares of Common Stock issuable hereunder
pursuant to the Securities Act of 1933 or any state securities laws. Any
certificates representing shares of Common Stock issued hereunder shall bear a
restrictive legend in such form and substance as counsel to the Company advises
the Company is required under applicable securities laws.

         9. Notices. Any notice, request or other document required or permitted
to be given or delivered to the Holder or the Company shall be delivered, or
shall be sent by certified or registered mail, postage prepaid, to the Holder at
its address as shown on the books of the Company or to the Company at the
address indicated therefor on the signature page of this Warrant.

         10. Binding Effect on Successors. This Warrant shall be binding upon
any corporation succeeding the Company by merger or consolidation. All of the
covenants and agreements of the Company contained herein shall inure to the
benefit of the permitted transferees of the Holder.

or in a particular instance, and either retroactively or prospectively), only
