               INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

          The following documents, which have been filed by Dotronix, Inc. (the
"Company") with the Securities and Exchange Commission, are incorporated by
reference in this Registration Statement, as of their respective dates:

         (a) the Company's Annual Report on Form 10-KSB40/A for the fiscal year
ended June 30, 1999, as filed December 1, 1999;

         (b) the Company's Quarterly Reports on Form 10-Q for the quarter ended
September 30, 1999, as filed November 15, 1999;

         (c) the description of the Company's Common Stock, par value $0.05 per
share, contained in Amendment No. 2 to the Company's Registration Statement on
Form S-18, SEC File No. 2-71333C, and any amendment or report filed for the
purpose of updating such description filed prior to the termination of the
offering described herein.

      All documents filed by the Company pursuant to Sections 13(a), 13(c),
14 or 15(d) of the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), subsequent to the date hereof and prior to the filing of a
post-effective amendment to this Registration Statement which indicates that
all securities offered hereby have been sold or which deregisters all
securities remaining unsold, shall be deemed to be incorporated by reference
herein and to be a part hereof from the respective dates of filing of such
documents.

ITEM 4.  DESCRIPTION OF SECURITIES.

      Not Applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

      Not Applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Section 302A.521, subd. 2, of the Minnesota Statutes requires the
Company to indemnify a person made or threatened to be made a party to a
proceeding by reason of the former or present official capacity of the person
with respect to the Company, against judgments, penalties, fines (including,
without limitation, excise taxes assessed against the person with respect to an
employee benefit plan), settlements, and reasonable expenses, including
attorneys' fees and disbursements, incurred by the person in connection with the
proceeding, if, with respect to the acts or omissions of the person complained
of in the proceeding, the person (1) has not been indemnified by another
organization or employee benefit plan for the same judgments, penalties or
fines; (2) acted in good faith; (3) received no improper personal benefit, and
statutory procedure has been followed in the case of any conflict of interest by
a director; (4) in the case of a criminal proceeding, had no reasonable cause to
believe the conduct was unlawful; and (5) in the case of acts or omissions
occurring in the person's performance in the official capacity of a director or,
for a person not a director, in the official capacity of an officer, board
committee member or employee, reasonably believed that the conduct was in the
best interests of the Company, or, in the case of performance by a director,
officer or employee of the Company involving service as a director, officer,
partner, trustee, employee or agent of another organization or employee benefit
plan, reasonably believed that the conduct was not opposed to the best interests
of the Company. In addition, Section 302A.521, subd. 3, requires payment by the
Company, upon written request, of reasonable expenses in advance of final
disposition of the proceeding in certain instances. A decision as to required
indemnification is made by a disinterested majority of the Board of Directors
present at a meeting at which a disinterested quorum is present, or by a
designated committee of the Board, by special legal counsel, by the
shareholders, or by a court.

<PAGE>

          Article X of the Bylaws of the Company provides that the Company shall
indemnify officers and directors to the extent permitted by Section 302A.521 as
now enacted or hereafter amended.

          Article XI of the Company's Articles of Incorporation, as amended,
provides that a director of the corporation shall not be personally liable to
the corporation or its shareholders for monetary damages for breach of
fiduciary duty as a director, except for liability (a) for any breach of the
director's duty of loyalty to the corporation or its shareholders, (b) for
acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (c) for authorizing a dividend, stock
repurchase or redemption or other distribution in violation of Minnesota law
or for violation of certain provisions of Minnesota securities laws, (d) for
any transaction from which the director derived an improper personal benefit,
or (e) for any act or omission occurring prior to the date when Article XI
became effective.

          Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers, or persons controlling
the Company pursuant to the foregoing provisions, the Company has been informed
that in the opinion of the Commission such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.

          (2) For determining any liability under the Securities Act of 1933, as
amended (the "Securities Act"), treat each post-effective amendment as a new

         (a) the Company's Annual Report on Form 10-KSB40/A for the fiscal year

      All documents filed by the Company pursuant to Sections 13(a), 13(c),

Act"), subsequent to the date hereof and prior to the filing of a

ITEM 4.  DESCRIPTION OF SECURITIES.

      Not Applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

      Not Applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          Section 302A.521, subd. 2, of the Minnesota Statutes requires the
Company to indemnify a person made or threatened to be made a party to a
proceeding by reason of the former or present official capacity of the person
with respect to the Company, against judgments, penalties, fines (including,
without limitation, excise taxes assessed against the person with respect to an
employee benefit plan), settlements, and reasonable expenses, including
attorneys' fees and disbursements, incurred by the person in connection with the
proceeding, if, with respect to the acts or omissions of the person complained
of in the proceeding, the person (1) has not been indemnified by another
organization or employee benefit plan for the same judgments, penalties or
fines; (2) acted in good faith; (3) received no improper personal benefit, and
statutory procedure has been followed in the case of any conflict of interest by
a director; (4) in the case of a criminal proceeding, had no reasonable cause to
believe the conduct was unlawful; and (5) in the case of acts or omissions
occurring in the person's performance in the official capacity of a director or,
for a person not a director, in the official capacity of an officer, board
committee member or employee, reasonably believed that the conduct was in the
best interests of the Company, or, in the case of performance by a director,
officer or employee of the Company involving service as a director, officer,
partner, trustee, employee or agent of another organization or employee benefit
plan, reasonably believed that the conduct was not opposed to the best interests
of the Company. In addition, Section 302A.521, subd. 3, requires payment by the
Company, upon written request, of reasonable expenses in advance of final
disposition of the proceeding in certain instances. A decision as to required
indemnification is made by a disinterested majority of the Board of Directors
present at a meeting at which a disinterested quorum is present, or by a
designated committee of the Board, by special legal counsel, by the
shareholders, or by a court.
Article X of the Bylaws of the Company provides that the Company shall
indemnify officers and directors to the extent permitted by Section 302A.521 as
now enacted or hereafter amended.

          Article XI of the Company's Articles of Incorporation, as amended,
provides that a director of the corporation shall not be personally liable to
the corporation or its shareholders for monetary damages for breach of
fiduciary duty as a director, except for liability (a) for any breach of the
director's duty of loyalty to the corporation or its shareholders, (b) for
acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (c) for authorizing a dividend, stock
repurchase or redemption or other distribution in violation of Minnesota law
or for violation of certain provisions of Minnesota securities laws, (d) for
any transaction from which the director derived an improper personal benefit,
or (e) for any act or omission occurring prior to the date when Article XI
became effective.

          Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers, or persons controlling
the Company pursuant to the foregoing provisions, the Company has been informed
that in the opinion of the Commission such indemnification is against public
policy as expressed in the Securities Act and is therefore unenforceable.
