EXHIBIT 10.11

                                OPTION AGREEMENT

         This AGREEMENT, dated as of April 7, 2004 (this "AGREEMENT"), is
entered into by and among Terry L. Myhre, an individual resident of the State of
Minnesota ("GRANTEE"), the William S. Sadler Estate (the "Estate"), and
Minnesota River Aviation, Inc., a Minnesota corporation ("MRAI," and together
with the Estate, the "GRANTORS").

         WHEREAS, the Estate and MRAI are holders of 574,159 and 704,800 shares
of common stock, par value $0.05 per share (the "COMMON STOCK"), of Dotronix,
Inc., a Minnesota corporation (the "COMPANY"), respectively.

         WHEREAS, the Grantors have agreed to grant to Grantee an option to
purchase shares of Common Stock, upon the terms and subject to the conditions
set forth herein.

         NOW, THEREFORE, the parties hereto agree as follows:

ARTICLE 1
STOCK OPTION

         Section 1.01. GRANT OF STOCK OPTION. The Grantors hereby grant Grantee
an irrevocable option (collectively, the "OPTION") to purchase, in the
aggregate, up to 1,000,000 shares of Common Stock (as the same may be adjusted
from time to time pursuant to Section 1.05, the "OPTIONED SHARES") at a purchase
price of $0.05 per Optioned Share (the "PURCHASE PRICE"), subject to the terms
and conditions provided herein.

         Section 1.02. EXERCISE OF OPTION. (a) Subject to the conditions below
and as set forth in 1.03 hereof, Grantee may exercise the Option, in whole or in
part, at any time or from time to time on any business day after the date hereof
and prior to 5:00 p.m., Minneapolis time, on November 5, 2010 (the "EXPIRATION
DATE"). If Grantee wishes to exercise the Option for all or some of the Optioned
Shares, Grantee shall send a written notice (the "EXERCISE NOTICE") to the
Grantors specifying the total number of Optioned Shares that Grantee wishes to
purchase pursuant to such exercise and the place (which shall be within the
State of Minnesota), the date of purchase (which shall be not less than one nor
more than 20 business days after the date of the Exercise Notice, and no later
than the Expiration Date), and the time for the closing of such purchase. Each
closing of a purchase of Optioned Shares (a "CLOSING") shall take place at the
place, on the date (the "CLOSING DATE") and at the time designated by Grantee in
the Exercise Notice; PROVIDED, HOWEVER, that if, at any Closing Date, the
conditions set forth in Section 1.04 shall not have been satisfied (or waived by
the Grantors), Grantee may postpone the Closing until a date within five
business days after such conditions are satisfied (but no later than the
Expiration Date).

         (b) The number of Optioned Shares that Grantee wishes to purchase
pursuant to each Exercise Notice shall be allocated between the Grantors based
upon mutual agreement of the Grantors. If the Grantors cannot mutually agree
upon such allocation prior to a given Closing, the Optioned Shares with respect
to such Closing shall be allocated first to the Estate and then to MRAI;
PROVIDED, HOWEVER, that in no event shall more than an aggregate of 574,159
shares of Common Stock be allocated to the Estate. The obligations of each
Grantor pursuant to this Agreement are several and not joint.

         (c) Grantee shall not be under any obligation to deliver any Exercise
Notice and may allow the Option to terminate without purchasing any Optioned
Shares hereunder; PROVIDED, HOWEVER, that once Grantee has delivered to the
Grantors an Exercise Notice, subject to the terms and conditions of this
Agreement, Grantee shall be bound to effect the purchase as described in such
Exercise Notice.

                                       60
<PAGE>

         (d) The Purchase Price for the Optioned Shares to be purchased upon any
exercise of the Option shall be payable, at Grantee's option, in cash or a
cashier's check.

         Section 1.03. CLOSING. At each Closing, (a) each Grantor shall deliver
to Grantee a certificate or certificates representing the Optioned Shares to be
purchased from such Grantor at such Closing (in the amount as provided in in
Section 1.02(b) hereof), in each case duly endorsed or accompanied by stock
powers duly executed in blank and (b) Grantee shall deliver to Grantors the
Purchase Price for such Optioned Shares.

         Section 1.04. CONDITIONS TO GRANTORS' OBLIGATIONS. The obligation of
Grantors to sell Optioned Shares at any Closing is subject to the following
conditions:

         (a) The representations and warranties of Grantee contained in Article
3 shall be true and correct at and as of the Closing Date as if made at and as
of such date, and the Grantors shall have received a certificate signed by
Grantee to the foregoing effect; and

         (b) There shall be no preliminary or permanent injunction or other
order, decree or ruling issued by a court of competent jurisdiction or by a
governmental, regulatory or administrative agency or commission, nor any
statute, rule, regulation or order promulgated or enacted by any governmental
authority, prohibiting or otherwise restraining the purchase and sale of such
Optioned Shares at the Closing.

         Section 1.05. ADJUSTMENT UPON CHANGE IN CAPITAL STOCK. In the event of
any change in the Company's capital stock by reason of any stock dividend, stock
split, reverse stock split, stock combination, recapitalization,
reclassification, exchange of securities, or extraordinary or liquidating
dividend or distribution, or in the event of any merger, reorganization, or
consolidation to which the Company is a party but is not the surviving entity,
then the number and kind of shares or securities subject to the Option and the
Purchase Price (but not the total purchase price for all Optioned Shares) shall
be appropriately and equitably adjusted so that Grantee shall receive, upon
exercise of the Option, and payment of the same total purchase price, the number
and class of shares or other securities or property that Grantee would have
received in respect of the Optioned Shares purchasable upon exercise of the
Option if the Option had been exercised immediately prior to such event.

interests.

         Section 2.03. EXCEPTION TO REPRESENTATIONS AND WARRANTIES.

Securities Act of 1933, as amended (the "Securities Act"), or whether Grantor,
upon the execution and delivery of this Agreement or upon his exercise of the
Option granted hereunder, might be deemed such an "affiliate." Grantor further
