ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

    The following documents previously filed (File No. 0-4804) with the
Securities and Exchange Commission (the "Commission") pursuant to the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), are, as of their
respective dates, incorporated by reference in this Registration Statement:

    (a)  The Annual Report on Form 10-K of Tennant Company (the "Company") for
the fiscal year ended December 31, 1996 (which incorporates by reference certain
portions of the Company's 1996 Annual Report to Shareholders, including
financial statements and accompanying information, and certain portions of the
Company's definitive proxy statement for the Company's 1997 Annual Meeting of
Shareholders);

    (b)  All other reports filed pursuant to Section 13(a) or 15(d) of the
Exchange Act since the end of the fiscal year covered by the Annual Report on
Form 10-K referred to in (a) above; and

    (c)  The description of the Company's Common Stock contained in a
registration statement filed pursuant to the Exchange Act, together with any
amendments or reports filed for the purpose of updating such description.

    In addition, all documents filed by the Company pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Exchange Act subsequent to the date of this
Registration Statement and prior to the filing of a post-effective amendment
that indicates that all shares of Common Stock offered have been sold, or that
deregisters all shares of Common Stock then remaining unsold, shall be deemed to
be incorporated by reference in, and to be a part of, this Registration
Statement from the date of filing of such documents.

    Any statement contained in a document incorporated, or deemed to be
incorporated, by reference herein shall be deemed to be modified or superseded
for purposes of this Registration Statement to the extent that a statement

ITEM 4.  DESCRIPTION OF SECURITIES.

    Not Applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

    Not Applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Article VI of the Company's Restated By-Laws provides that the Company
shall indemnify its directors and officers to the full extent required by
Minnesota Statutes, Section 302A.521, or by other provisions of law.  Section
302A.521 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 


                                         II-1

<PAGE>

an employee benefit plan), settlements and reasonable expenses, including
attorneys' fees and disbursements, incurred by such person in connection with
the proceeding, if certain criteria are met.  These criteria, all of which must
be met by the person seeking indemnification, are: (a) such person has not been
indemnified by another organization for the same judgments, penalties, fines,
settlements and expenses; (b) such person must have acted in good faith; (c) no
improper personal benefit was obtained by such person and, if applicable,
certain statutory conflict of interest provisions have been satisfied; (d) in
the case of a criminal proceeding,  such person had no reasonable cause to
believe that the conduct was unlawful; and (e) such person acted in a manner he
or she reasonably believed was in the best interests of the corporation or, in
certain limited circumstances, not opposed to the best interests of the
corporation.  The determination as to eligibility for indemnification is made by
the members of the corporation's board of directors, or a committee thereof, who
are at the time not parties to the proceedings under consideration, by special
legal counsel, by the shareholders who are not parties to the proceedings or by
a court.

    Article VIII of the Company's Restated Articles of Incorporation provides
that no director shall be personally liable to the Company or its shareholders
for monetary damages for breach of fiduciary duty as director, except: (i) any
breach of the director's duty of loyalty to the Company or its shareholders;
(ii) acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law; (iii) dividends, stock repurchases and other
distributions made in violation of Minnesota law or for violations of the
Minnesota securities laws; (iv) any transaction from which the director derived
an improper personal benefit; or (v) any act or omission occurring prior to the
effective date of the provision in the Company's Restated Articles of
Incorporation limiting such liability.  This Article does not affect the
availability of equitable remedies, such as an action to enjoin or rescind a
transaction involving a breach of fiduciary duty, although, as a practical
matter, equitable relief may not be available.  Nor does this Article limit the
liability of directors for violations of, or relieve them from the necessity of
complying with, the federal securities laws.

ITEM 3.  INCORPORATION OF DOCUMENTS BY REFERENCE.

    The following documents previously filed (File No. 0-4804) with the
Securities and Exchange Commission (the "Commission") pursuant to the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), are, as of their
respective dates, incorporated by reference in this Registration Statement:

    (a)  The Annual Report on Form 10-K of Tennant Company (the "Company") for
the fiscal year ended December 31, 1996 (which incorporates by reference certain
portions of the Company's 1996 Annual Report to Shareholders, including
financial statements and accompanying information, and certain portions of the
Company's definitive proxy statement for the Company's 1997 Annual Meeting of
Shareholders);

    (b)  All other reports filed pursuant to Section 13(a) or 15(d) of the
Exchange Act since the end of the fiscal year covered by the Annual Report on
Form 10-K referred to in (a) above; and

    (c)  The description of the Company's Common Stock contained in a
registration statement filed pursuant to the Exchange Act, together with any
amendments or reports filed for the purpose of updating such description.

    In addition, all documents filed by the Company pursuant to Sections 13(a),
13(c), 14 and 15(d) of the Exchange Act subsequent to the date of this
Registration Statement and prior to the filing of a post-effective amendment
that indicates that all shares of Common Stock offered have been sold, or that
deregisters all shares of Common Stock then remaining unsold, shall be deemed to
be incorporated by reference in, and to be a part of, this Registration
Statement from the date of filing of such documents.

    Any statement contained in a document incorporated, or deemed to be
incorporated, by reference herein shall be deemed to be modified or superseded
for purposes of this Registration Statement to the extent that a statement
contained herein or incorporated herein by reference or in any other

ITEM 4.  DESCRIPTION OF SECURITIES.

    Not Applicable.

ITEM 5.  INTERESTS OF NAMED EXPERTS AND COUNSEL.

    Not Applicable.

ITEM 6.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Article VI of the Company's Restated By-Laws provides that the Company
shall indemnify its directors and officers to the full extent required by
Minnesota Statutes, Section 302A.521, or by other provisions of law.  Section
302A.521 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 

                                         II-1
an employee benefit plan), settlements and reasonable expenses, including
attorneys' fees and disbursements, incurred by such person in connection with
the proceeding, if certain criteria are met.  These criteria, all of which must
be met by the person seeking indemnification, are: (a) such person has not been
indemnified by another organization for the same judgments, penalties, fines,
settlements and expenses; (b) such person must have acted in good faith; (c) no
improper personal benefit was obtained by such person and, if applicable,
certain statutory conflict of interest provisions have been satisfied; (d) in
the case of a criminal proceeding,  such person had no reasonable cause to
believe that the conduct was unlawful; and (e) such person acted in a manner he
or she reasonably believed was in the best interests of the corporation or, in
certain limited circumstances, not opposed to the best interests of the
corporation.  The determination as to eligibility for indemnification is made by
the members of the corporation's board of directors, or a committee thereof, who
are at the time not parties to the proceedings under consideration, by special
legal counsel, by the shareholders who are not parties to the proceedings or by
a court.

    Article VIII of the Company's Restated Articles of Incorporation provides
that no director shall be personally liable to the Company or its shareholders
for monetary damages for breach of fiduciary duty as director, except: (i) any
breach of the director's duty of loyalty to the Company or its shareholders;
(ii) acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law; (iii) dividends, stock repurchases and other
distributions made in violation of Minnesota law or for violations of the
Minnesota securities laws; (iv) any transaction from which the director derived
an improper personal benefit; or (v) any act or omission occurring prior to the
effective date of the provision in the Company's Restated Articles of
Incorporation limiting such liability.  This Article does not affect the
availability of equitable remedies, such as an action to enjoin or rescind a
transaction involving a breach of fiduciary duty, although, as a practical
matter, equitable relief may not be available.  Nor does this Article limit the
liability of directors for violations of, or relieve them from the necessity of
complying with, the federal securities laws.
