ITEM 4.           DESCRIPTION OF SECURITIES.

         Not applicable.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Michigan Business Corporation Act ("MBCA") of the State of Michigan
provides that a Michigan corporation, such as the Corporation, may indemnify a
director or officer against his or her expenses and judgments, fines and amounts
paid in settlement actually and reasonably incurred in connection with any
action, suit or proceeding (other than an action by or in the right of the
corporation) involving such person by reason of the fact that such person is or
was a director or officer, concerning actions taken in good faith and in a
manner reasonably believed to be in or not opposed to the best interest of the
corporation and, with respect to any criminal action or proceeding, without
reasonable cause to believe his or her conduct was unlawful. The MBCA also
provides that in a derivative action, a Michigan corporation may indemnify its
directors and officers against expenses actually and reasonably incurred to the
extent that such director or officer acted in good faith and in a manner such
director or officer reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification may be made with
respect to any claim, issue or matter as to which such director or officer is
adjudged to be liable to the corporation unless and only to the extent that the
court determines upon application that, despite the adjudication of liability
but in view of all the circumstances of the case, such director or officer is
fairly and reasonably entitled to indemnity for such expenses as the court deems
proper. The MBCA also generally permits the advancement of a director's or
officer's expenses, including by means of a mandatory charter or bylaw provision
to that effect, in lieu of requiring the authorization of such advancement by
the Board of Directors in specific cases. Article VI of the Corporation's
articles of incorporation addresses such an issue and reads as follows:

         "1. A director is not personally liable to the Corporation or its
shareholders for monetary damages for a breach of the director's fiduciary duty.
However, this provision does not eliminate or limit the liability of a director
for any of the following:



                                        3

<PAGE>



                  (a)      A breach of the director's duty of loyalty to the
                           corporation or its shareholders.

                  (b)      Acts or omissions not in good faith or that involve
                           intentional misconduct or knowing violation of law.

                  (c)      A transaction from which the director derived an
                           improper personal benefit.

                  (d)      An act or omission occurring before March 1, 1987 to
                           the extent such act or omission was a violation of
                           law prior to that date.

                  (e)      Declaration of a dividend or distribution of assets
                           of the Corporation, purchase of shares of the
                           Corporation, or making a loan to an officer,
                           director, or employee of the Corporation in violation
                           of an applicable statute or the Corporation's
                           articles or bylaws, unless the director acted in good
                           faith and with that degree of diligence, care and
                           skill which an ordinarily prudent person would
                           exercise under similar circumstances in a like
                           position; provided, that in discharging his or her
                           duties, a director, when acting in good faith, may
                           rely on the opinion of counsel of the Corporation,
                           upon the report of an independent appraiser selected
                           with reasonable care by the board, or upon financial
                           statements of the Corporation represented to him or
                           her as correct by the president or officer of the
                           Corporation having charge of the books of account or
                           stated in a written report by an independent public
                           or certified public accountant or firm of such
                           accountants fairly to reflect the financial condition
                           of the Corporation.

         "2. The Corporation has the power to indemnify a person who was or is a
party or is threatened to be made a party to a threatened, pending, or completed
action, suit, or proceeding, whether civil, criminal, administrative, or
investigative and whether formal or informal, other than an action by or in the
right of the Corporation, by reason of the fact that he or she is or was a
director, officer, employee, or agent of the Corporation, or is or was serving
at the request of the Corporation as director, officer, partner, trustee,
employee, or agent of another foreign or domestic corporation, partnership,
joint venture, trust, or other enterprise, whether for profit or not, against
expenses, including attorneys' fees, judgments, penalties, fines, and amounts
paid in settlement actually and reasonably incurred by him or her in connection
with the action, suit, or proceeding, if the 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 or its shareholders, and with respect to a criminal
action or proceeding, if the person had no reasonable cause to believe his or
her conduct was unlawful. The termination of an action, suit, or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, does not, of itself, create a



                                       4

<PAGE>


presumption that the person did not act in good faith and in a manner which he
or she reasonably believed to be in or not opposed to the best interests of the
Corporation or its shareholders, and, with respect to a criminal action or
proceeding, had reasonable cause to believe that his or her conduct was
unlawful.

         "3. The Corporation has the power to indemnify a person who was or is a
party to or is threatened to be made a party to a threatened, pending, or
completed action or suit by or in the right of the Corporation to procure a
judgment in its favor by reason of the fact that he or she is or was a director,
officer, employee, or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, partner, trustee, employee,
or agent of another foreign or domestic corporation, partnership, joint venture,
trust, or other enterprise, whether for profit or not, against expenses,
including actual and reasonable attorneys' fees, and amounts paid in settlement
incurred by the person in connection with the action or suit, if the person
acted in good faith and in a manner the person reasonably believed to be in or
not opposed to the best interests of the Corporation or its shareholders.
However, indemnification shall not be made for a claim, issue, or matter in
which the person has been found liable to the Corporation unless and only to the
extent that the court in which the action was brought has determined upon
application that despite the adjudication of liability but in view of all
circumstances of the case, the person is fairly and reasonably entitled to
indemnification for the expenses which the court considers proper.

         "4. (a) To the extent that a director, officer, employee, or agent of
the Corporation has been successful on the merits or otherwise in defense of an
action, suit, or proceeding referred in section 2 or 3 above, or in defense of a
claim, issue, or matter in the action, suit, or matter in the action, suit, or
proceeding, he or she shall be indemnified against expenses, including actual
and reasonable attorneys' fees, incurred by him or her in connection with the
action, suit, or proceeding and an action, suit, or proceeding brought to
enforce the mandatory indemnification provided in this subsection.

                  (b) An indemnification under section 2 or 3, unless ordered by
a court, shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee, or agent is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in section 2 or 3. This determination
shall be made in any of the following ways:

                  (i)      By a majority vote of a quorum of the board
                           consisting of directors who were not parties to the
                           action, suit, or proceeding.
                  (ii)     If the quorum described in subdivision (i) is not
                           obtainable, then by a majority vote of a committee of
                           directors who are not parties to the action. The
                           committee shall consist of not less than 2
                           disinterested directors.
                  (iii)    By independent legal counsel in a written opinion.
                  (iv)     By the shareholders.

                  (c) If a person is entitled to indemnification under section 2
or 3 for a portion of expenses including attorneys' fees, judgments, penalties,
fines, and amounts paid in settlement, but not for the total amount thereof, the
Corporation may indemnify the person for the portion of





                                       5
<PAGE>



the expenses, judgments, penalties, fines, or amounts paid in settlement for
which the person is entitled to be indemnified.

         "5. Expenses incurred in defending a civil or criminal action, suit, or
proceeding described in section 2 or 3 may be paid by the Corporation in advance
of the final disposition of the action, suit, or proceeding upon receipt of an
undertaking by or on behalf of the director, officer, employee, or agent to
repay the expenses if it is ultimately determined that the person is not
entitled to be indemnified by the Corporation. The undertaking shall be by
unlimited general obligation of the person on whose behalf advances are made but
need not be secured.

         "6. The indemnification provided in sections 2 to 5 continues as to a
person who ceases to be a director, officer, employee, or agent and shall inure
to the benefit of the heirs, executors, and administrators of the person.

         "7. The Corporation shall have power to purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or agent of
the Corporation or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, whether for profit or not, against any
liability asserted against him or her and incurred by him or her in any such
capacity or arising out of his or her status as such, whether or not the
Corporation would have the power to indemnify him or her against such liability
under the provisions of this Article.

         "8. For purposes of sections 2 to 7 'corporation' includes all
constituent corporations absorbed in a consolidation or merger and the resulting
or surviving corporation, so that a person who is or was a director, officer,
employee, or agent of the constituent corporation as a director, officer,
partner, trustee, employee or agent of another foreign or domestic corporation,
partnership, joint venture, trust, or other enterprise whether for profit or not
shall stand in the same position under the provisions of this Article with
respect to the resulting or surviving corporation as the person would if he or
she had served the resulting or surviving corporation in the same capacity."

         Insurance is maintained on a regular basis (and not specifically in
connection with this offering) against liabilities arising on the part of
directors and officers out of their performance in such capacities or arising on
the part of the Corporation out of its foregoing indemnification provisions,
subject to certain exclusions and to the policy limits.

                  for the quarter ended September 30, 1996, Commission File

                  registration statement).

ITEM 9.           UNDERTAKINGS.

         A.       The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

                  (i) To include any prospectus required by Section 10 (a) (3)
of the Securities Act of 1933;

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement;

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;

         Provided, however, that paragraphs A(l)(i) and A(l)(ii) shall not apply
if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic


                                       7


<PAGE>


reports filed by the registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, 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.

         B. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         C. Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions described in Item 6 above,
or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant 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 Registrant 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 Act and
will be governed by the final adjudication of such issue.

ITEM 5.           INTERESTS OF NAMED EXPERTS AND COUNSEL.

         Not applicable.

ITEM 6.           INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         The Michigan Business Corporation Act ("MBCA") of the State of Michigan
provides that a Michigan corporation, such as the Corporation, may indemnify a
director or officer against his or her expenses and judgments, fines and amounts
paid in settlement actually and reasonably incurred in connection with any
action, suit or proceeding (other than an action by or in the right of the
corporation) involving such person by reason of the fact that such person is or
was a director or officer, concerning actions taken in good faith and in a
manner reasonably believed to be in or not opposed to the best interest of the
corporation and, with respect to any criminal action or proceeding, without
reasonable cause to believe his or her conduct was unlawful. The MBCA also
provides that in a derivative action, a Michigan corporation may indemnify its
directors and officers against expenses actually and reasonably incurred to the
extent that such director or officer acted in good faith and in a manner such
director or officer reasonably believed to be in or not opposed to the best
interests of the corporation, except that no indemnification may be made with
respect to any claim, issue or matter as to which such director or officer is
adjudged to be liable to the corporation unless and only to the extent that the
court determines upon application that, despite the adjudication of liability
but in view of all the circumstances of the case, such director or officer is
fairly and reasonably entitled to indemnity for such expenses as the court deems
proper. The MBCA also generally permits the advancement of a director's or
officer's expenses, including by means of a mandatory charter or bylaw provision
to that effect, in lieu of requiring the authorization of such advancement by
the Board of Directors in specific cases. Article VI of the Corporation's
articles of incorporation addresses such an issue and reads as follows:

         "1. A director is not personally liable to the Corporation or its
shareholders for monetary damages for a breach of the director's fiduciary duty.
However, this provision does not eliminate or limit the liability of a director
for any of the following:

                                        3
(a)      A breach of the director's duty of loyalty to the
                           corporation or its shareholders.

                  (b)      Acts or omissions not in good faith or that involve
                           intentional misconduct or knowing violation of law.

                  (c)      A transaction from which the director derived an
                           improper personal benefit.

                  (d)      An act or omission occurring before March 1, 1987 to
                           the extent such act or omission was a violation of
                           law prior to that date.

                  (e)      Declaration of a dividend or distribution of assets
                           of the Corporation, purchase of shares of the
                           Corporation, or making a loan to an officer,
                           director, or employee of the Corporation in violation
                           of an applicable statute or the Corporation's
                           articles or bylaws, unless the director acted in good
                           faith and with that degree of diligence, care and
                           skill which an ordinarily prudent person would
                           exercise under similar circumstances in a like
                           position; provided, that in discharging his or her
                           duties, a director, when acting in good faith, may
                           rely on the opinion of counsel of the Corporation,
                           upon the report of an independent appraiser selected
                           with reasonable care by the board, or upon financial
                           statements of the Corporation represented to him or
                           her as correct by the president or officer of the
                           Corporation having charge of the books of account or
                           stated in a written report by an independent public
                           or certified public accountant or firm of such
                           accountants fairly to reflect the financial condition
                           of the Corporation.

         "2. The Corporation has the power to indemnify a person who was or is a
party or is threatened to be made a party to a threatened, pending, or completed
action, suit, or proceeding, whether civil, criminal, administrative, or
investigative and whether formal or informal, other than an action by or in the
right of the Corporation, by reason of the fact that he or she is or was a
director, officer, employee, or agent of the Corporation, or is or was serving
at the request of the Corporation as director, officer, partner, trustee,
employee, or agent of another foreign or domestic corporation, partnership,
joint venture, trust, or other enterprise, whether for profit or not, against
expenses, including attorneys' fees, judgments, penalties, fines, and amounts
paid in settlement actually and reasonably incurred by him or her in connection
with the action, suit, or proceeding, if the 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 or its shareholders, and with respect to a criminal
action or proceeding, if the person had no reasonable cause to believe his or
her conduct was unlawful. The termination of an action, suit, or proceeding by
judgment, order, settlement, conviction, or upon a plea of nolo contendere or
its equivalent, does not, of itself, create a

                                       4
presumption that the person did not act in good faith and in a manner which he
or she reasonably believed to be in or not opposed to the best interests of the
Corporation or its shareholders, and, with respect to a criminal action or
proceeding, had reasonable cause to believe that his or her conduct was
unlawful.

         "3. The Corporation has the power to indemnify a person who was or is a
party to or is threatened to be made a party to a threatened, pending, or
completed action or suit by or in the right of the Corporation to procure a
judgment in its favor by reason of the fact that he or she is or was a director,
officer, employee, or agent of the Corporation, or is or was serving at the
request of the Corporation as a director, officer, partner, trustee, employee,
or agent of another foreign or domestic corporation, partnership, joint venture,
trust, or other enterprise, whether for profit or not, against expenses,
including actual and reasonable attorneys' fees, and amounts paid in settlement
incurred by the person in connection with the action or suit, if the person
acted in good faith and in a manner the person reasonably believed to be in or
not opposed to the best interests of the Corporation or its shareholders.
However, indemnification shall not be made for a claim, issue, or matter in
which the person has been found liable to the Corporation unless and only to the
extent that the court in which the action was brought has determined upon
application that despite the adjudication of liability but in view of all
circumstances of the case, the person is fairly and reasonably entitled to
indemnification for the expenses which the court considers proper.

         "4. (a) To the extent that a director, officer, employee, or agent of
the Corporation has been successful on the merits or otherwise in defense of an
action, suit, or proceeding referred in section 2 or 3 above, or in defense of a
claim, issue, or matter in the action, suit, or matter in the action, suit, or
proceeding, he or she shall be indemnified against expenses, including actual
and reasonable attorneys' fees, incurred by him or her in connection with the
action, suit, or proceeding and an action, suit, or proceeding brought to
enforce the mandatory indemnification provided in this subsection.

                  (b) An indemnification under section 2 or 3, unless ordered by
a court, shall be made by the Corporation only as authorized in the specific
case upon a determination that indemnification of the director, officer,
employee, or agent is proper in the circumstances because he or she has met the
applicable standard of conduct set forth in section 2 or 3. This determination
shall be made in any of the following ways:

                  (i)      By a majority vote of a quorum of the board
                           consisting of directors who were not parties to the
                           action, suit, or proceeding.
                  (ii)     If the quorum described in subdivision (i) is not
                           obtainable, then by a majority vote of a committee of
                           directors who are not parties to the action. The
                           committee shall consist of not less than 2
                           disinterested directors.
                  (iii)    By independent legal counsel in a written opinion.
                  (iv)     By the shareholders.

                  (c) If a person is entitled to indemnification under section 2
or 3 for a portion of expenses including attorneys' fees, judgments, penalties,
fines, and amounts paid in settlement, but not for the total amount thereof, the
Corporation may indemnify the person for the portion of

                                       5
the expenses, judgments, penalties, fines, or amounts paid in settlement for
which the person is entitled to be indemnified.

         "5. Expenses incurred in defending a civil or criminal action, suit, or
proceeding described in section 2 or 3 may be paid by the Corporation in advance
of the final disposition of the action, suit, or proceeding upon receipt of an
undertaking by or on behalf of the director, officer, employee, or agent to
repay the expenses if it is ultimately determined that the person is not
entitled to be indemnified by the Corporation. The undertaking shall be by
unlimited general obligation of the person on whose behalf advances are made but
need not be secured.

         "6. The indemnification provided in sections 2 to 5 continues as to a
person who ceases to be a director, officer, employee, or agent and shall inure
to the benefit of the heirs, executors, and administrators of the person.

         "7. The Corporation shall have power to purchase and maintain insurance
on behalf of any person who is or was a director, officer, employee or agent of
the Corporation or is or was serving at the request of the Corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, whether for profit or not, against any
liability asserted against him or her and incurred by him or her in any such
capacity or arising out of his or her status as such, whether or not the
Corporation would have the power to indemnify him or her against such liability
under the provisions of this Article.

         "8. For purposes of sections 2 to 7 'corporation' includes all
constituent corporations absorbed in a consolidation or merger and the resulting
or surviving corporation, so that a person who is or was a director, officer,
employee, or agent of the constituent corporation as a director, officer,
partner, trustee, employee or agent of another foreign or domestic corporation,
partnership, joint venture, trust, or other enterprise whether for profit or not
shall stand in the same position under the provisions of this Article with
respect to the resulting or surviving corporation as the person would if he or
she had served the resulting or surviving corporation in the same capacity."

         Insurance is maintained on a regular basis (and not specifically in
connection with this offering) against liabilities arising on the part of
directors and officers out of their performance in such capacities or arising on
the part of the Corporation out of its foregoing indemnification provisions,
subject to certain exclusions and to the policy limits.

                  for the quarter ended September 30, 1996, Commission File

ITEM 9.           UNDERTAKINGS.

         A.       The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

                  (i) To include any prospectus required by Section 10 (a) (3)
of the Securities Act of 1933;

                  (ii) To reflect in the prospectus any facts or events arising
after the effective date of the registration statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in the registration
statement. Notwithstanding the foregoing, any increase or decrease in volume of
securities offered (if the total dollar value of securities offered would not
exceed that which was registered) and any deviation from the low or high end of
the estimated maximum offering range may be reflected in the form of prospectus
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the
changes in volume and price represent no more than 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee"
table in the effective registration statement;

                  (iii) To include any material information with respect to the
plan of distribution not previously disclosed in the registration statement or
any material change to such information in the registration statement;

         Provided, however, that paragraphs A(l)(i) and A(l)(ii) shall not apply
if the information required to be included in a post-effective amendment by
those paragraphs is contained in periodic

                                       7
reports filed by the registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

         (2) That, for the purpose of determining any liability under the
Securities Act of 1933, 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.

         B. The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         C. Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions described in Item 6 above,
or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant 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 Registrant 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 Act and
will be governed by the final adjudication of such issue.
