          If any Participant shall dispute the correctness or applicability to
such Participant of a calculation of the Participants benefits under this Plan
or the applicability of any rule, procedure or regulation as applied to such
Participant, or if any Employee shall dispute or question a determination
concerning such Employee's right to participate under the Plan, such person

questions to the Plan Administrator.  If a claim is wholly or partially denied,
the Plan Administrator shall, within a reasonable period of time, but not later

written notice setting forth in a manner calculated to be understood by the
claimant:

               (b)  Specific reference to the pertinent Plan provisions on which
the denial is based;

               (c)  A description of any additional material or information

          A Participant whose claim for benefits under the Plan has been denied,
or his duly authorized representative, may request a review upon written
application to the Plan Administrator, may review pertinent documents, and may
submit issues and comments in writing.  The claimant's written request for
review must be submitted to the Plan Administrator within sixty (60) days after
receipt by the claimant of written notification of the

                                       11


denial of a claim. A decision by the Plan Administrator shall be made promptly,
and not later than sixty (60) days after the Plan Administrator's receipt of a
request for review, unless special circumstances require an extension of time
for proceeding, in which case a decision shall be rendered as soon as possible,
but not later than one hundred twenty (120) days after receipt of the request
for review. The decision on review shall be in writing and shall include
specific reasons for the decision, specific reference to the pertinent Plan
provision on which the decision is based, and be written in a manner calculated
to be understood by the claimant.

                           MISCELLANEOUS PROVISIONS
                           ------------------------

          11.1 Indemnification for Liability. The Corporation shall, to the full
extent permitted by applicable state and federal law, indemnify any board
member, officer or employee of the Corporation who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (whether civil, criminal, administrative or investigative)
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner which he
reasonably believed to be solely in the interest of the Participants and
beneficiaries of the Plan, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful;
provided further that:

               (a)  A person who discharges his duties with respect to the Plan
in a manner which he believes to be solely in the interest of its Participants
and beneficiaries shall be deemed to have acted in a manner which he reasonably
believes to be in (or not opposed to) the best interest of the Corporation;

               (b)  This indemnification shall continue as to a person who has
ceased to be a director, officer, or employee and shall inure to the benefit of
the heirs, executors and administrators of such person;

               (c)  The Corporation may retain such accountants, counsel or
other specialists as it deems necessary or desirable in connection with the
administration of the Plan and any beneficiary of this indemnity shall be
entitled to rely conclusively upon, and shall be fully protected and indemnified
in any action taken in good faith reliance upon any

                                       14


opinions or reports furnished to it in writing by such accountants, counsel or
other specialists.

          11.2 Not an Employment Contract. The establishment of the Plan, the
creation of any account, or the payment of any benefit does not create in any
Employee, Participant or other party a right to continuing employment with the
Corporation.

          11.3 No Liability for Elections. The Corporation shall not be liable
for any Participant's election under the Plan, nor shall the Corporation be
deemed to have made any representations as to the value with respect to any
Participant of any benefits offered under the Plan.

          11.4 Construction of Plan. This Plan shall be construed, administered
and governed in all respects under applicable federal law, and to the extent
that federal law is inapplicable, under the laws of the State of Michigan.

          11.5 Severability. Should any part of the Plan subsequently be
invalidated by a court of competent jurisdiction, the remainder thereof shall be
given effect to the maximum extent possible.

          11.6 Fiscal Records and Reports. The fiscal records of the Plan are to
be maintained on the basis of the Plan Year. The Plan Administrator shall
exercise such authority and responsibility as it deems appropriate in order to
comply with the terms of the Plan relating to Participant records which are
maintained under this Plan.

          11.7 Headings. The headings contained in the Plan are for reference
only, and they do not in any manner limit or expand the terms and provisions of
the Plan.

          11.8 No Vested Interest. Except for the right to receive any benefit
payable under the Plan, no person shall have any right, title or interest in or
to the assets of the Corporation because of the Plan.

                                       15


          11.9  Limit on Liability. Nothing contained in the Plan shall impose
on the Corporation, or any board members, officers or employees of the
Corporation any liability for the payment of benefits under this Plan other than
liabilities resulting from willful neglect or fraud. The liability of the
Corporation for benefits shall be limited to the benefits provided under the
Plan. Persons entitled to benefits under the Plan shall look only to the
Corporation for payment.

          11.10 Anti-Alienation.  To the extent permitted by law, the right of
any Participant or any beneficiary to any benefit or to any payment hereunder
shall not be subject in any manner to attachment or other legal process for the
debts of such Participant or beneficiary; and any such benefit or payment shall
not be subject to anticipation, alienation, sale, transfer, assignment, or
encumbrance.

          IN WITNESS WHEREOF, the Corporation has caused this First Amendment
and Restatement of this Plan to be executed in its name and behalf  effective
January 1, 1989.
