ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Frank R. Reynolds, a director of the Company, is a principal in the law
firm of Reynolds and Reynolds, Ltd., and has served as legal counsel for the
Company since 1975. It is anticipated that he will perform legal services for
the Company in 2000 as well. During the year ended December 31, 1999, the
Company paid $66,000 in legal fees to his firm.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Sec. 8.75 of the Illinois Business Corporation Act provides that a
corporation may indemnify directors and officers for expenses reasonably
incurred in defending an action brought against them based on their actions in
that capacity if such person acted in good faith and in a manner he or she
reasonably believed to be in, or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his or her conduct was unlawful. A corporation may
indemnify a director or officer in a derivative suit if such person acted in
good faith and in a manner he or she reasonably believed to be in, or not
opposed to, the best interests of the corporation, unless such person has been
adjudged to have been liable to the corporation. A corporation may purchase
directors and officers' insurance ("D&O Insurance") whether or not the
corporation would have the power to indemnify such person against such liability
under the provisions of this Section. ARTICLES OF INCORPORATION

         By Amendment dated February 10, 1987, the shareholders amended Article
Eight of the Articles of Incorporation to read:

                  The Corporation shall indemnify any officer and director who
         was or is a party to or is threatened to be made a party to any
         threatened, pending or completed action, suit or proceedings, whether
         civil, criminal, administrative or investigative (other than an action
         by or in the right of the corporation) by reason of the fact that he is
         or was a director or officer of the corporation to the fullest extent
         as provided in the Illinois Business Corporation Act of 1983 and as
         amended from time to time.

                  The Corporation shall, to the full extent permitted by the
         Illinois Corporation Act of 1983 as amended and to the full extent as
         amended in the future, indemnify all directors and officers pursuant to
         the provisions thereto.

         INSURANCE

         The Company has entered into a contract with Great American Insurance
Company for D&O Insurance. The policy covers the Company up to $7,000,000 each
year for amounts that the Company pays to its directors and officers as
indemnification under the Company's Articles of Incorporation.

ITEM 9. UNDERTAKINGS.

1.       The Company hereby undertakes:

         (1)      To file, during any period in which offers or sales are being
                  made of the securities registered hereby, a post-effective
                  amendment to this Registration Statement to include any
                  material information with respect to the plan of distribution
                  not previously disclosed in this Registration Statement or any
                  material change to such information in this Registration
                  Statement.

         (2)      That, for the purpose of determining any liability under the
                  Securities Act, each such post-effective amendment shall be
                  deemed to be a new registration statement relating to the
                  securities offered therein, and the offering of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

         (3)      To remove from registration by means of a post-effective
                  amendment any of the securities being registered which remain
                  unsold at the termination of the offering.

         (4)      That, for purposes of determining any liability under the
                  Securities Act, each filing of the Company's annual report
                  pursuant to Section 13(a) or Section 15(d) of the Exchange Act
                  (and, where applicable, each filing of an employee benefit
                  plan's annual report pursuant to Section 15(d) of the Exchange
                  Act) that is incorporated by reference in this Registration
                  Statement shall be deemed to be a new registration statement
                  relating to the securities offered therein, and the offering
                  of such securities at that time shall be deemed to be the
                  initial bona fide offering thereof.

2.       Commission Position on Indemnification.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
Company will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

         Frank R. Reynolds, a director of the Company, is a principal in the law
firm of Reynolds and Reynolds, Ltd., and has served as legal counsel for the
Company since 1975. It is anticipated that he will perform legal services for
the Company in 2000 as well. During the year ended December 31, 1999, the

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Sec. 8.75 of the Illinois Business Corporation Act provides that a
corporation may indemnify directors and officers for expenses reasonably
incurred in defending an action brought against them based on their actions in
that capacity if such person acted in good faith and in a manner he or she
reasonably believed to be in, or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his or her conduct was unlawful. A corporation may
indemnify a director or officer in a derivative suit if such person acted in
good faith and in a manner he or she reasonably believed to be in, or not
opposed to, the best interests of the corporation, unless such person has been
adjudged to have been liable to the corporation. A corporation may purchase
directors and officers' insurance ("D&O Insurance") whether or not the
corporation would have the power to indemnify such person against such liability
under the provisions of this Section. ARTICLES OF INCORPORATION

         By Amendment dated February 10, 1987, the shareholders amended Article
Eight of the Articles of Incorporation to read:

                  The Corporation shall indemnify any officer and director who
         was or is a party to or is threatened to be made a party to any
         threatened, pending or completed action, suit or proceedings, whether
         civil, criminal, administrative or investigative (other than an action
         by or in the right of the corporation) by reason of the fact that he is
         or was a director or officer of the corporation to the fullest extent
         as provided in the Illinois Business Corporation Act of 1983 and as
         amended from time to time.

                  The Corporation shall, to the full extent permitted by the
         Illinois Corporation Act of 1983 as amended and to the full extent as
         amended in the future, indemnify all directors and officers pursuant to
         the provisions thereto.

         INSURANCE

         The Company has entered into a contract with Great American Insurance
Company for D&O Insurance. The policy covers the Company up to $7,000,000 each
year for amounts that the Company pays to its directors and officers as
indemnification under the Company's Articles of Incorporation.

ITEM 9. UNDERTAKINGS.

1.       The Company hereby undertakes:

         (1)      To file, during any period in which offers or sales are being
                  made of the securities registered hereby, a post-effective
                  amendment to this Registration Statement to include any
                  material information with respect to the plan of distribution
                  not previously disclosed in this Registration Statement or any
                  material change to such information in this Registration
                  Statement.

         (2)      That, for the purpose of determining any liability under the
                  Securities Act, each such post-effective amendment shall be
                  deemed to be a new registration statement relating to the
                  securities offered therein, and the offering of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof.

         (3)      To remove from registration by means of a post-effective
                  amendment any of the securities being registered which remain
                  unsold at the termination of the offering.

         (4)      That, for purposes of determining any liability under the
                  Securities Act, each filing of the Company's annual report
                  pursuant to Section 13(a) or Section 15(d) of the Exchange Act
                  (and, where applicable, each filing of an employee benefit
                  plan's annual report pursuant to Section 15(d) of the Exchange
                  Act) that is incorporated by reference in this Registration
                  Statement shall be deemed to be a new registration statement
                  relating to the securities offered therein, and the offering
                  of such securities at that time shall be deemed to be the
                  initial bona fide offering thereof.

2.       Commission Position on Indemnification.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company has been
advised that in the opinion of the Commission such indemnification is against
public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Company of expenses incurred or paid
by a director, officer or controlling person of the Company in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
Company will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
