                               ARTICLE VIII

                            General Provisions

     Section 8.1  Except as otherwise expressly provided herein, all
terms and conditions of the Retirement Plan applicable to a retirement
benefit or a surviving spouse benefit shall also be applicable to a
retirement benefit or a surviving spouse benefit payable hereunder.  Any
Plan retirement benefit or surviving spouse benefit, or any other benefit
payable under the Plan, shall be paid solely in accordance with the terms
and conditions of the Retirement Plan and nothing in this Plan shall
operate or be construed in any way to modify, amend or affect the terms
and provisions of the Retirement Plan.

     Section 8.2  Nothing contained in the Plan shall constitute a
guaranty by the Company or any other entity or person that the assets of
the Company will be sufficient to pay any benefit hereunder.  The
benefits under this Plan shall not be funded, but shall constitute
liabilities of the Company payable when due.

     Section 8.3  No Participant or Surviving Spouse shall have any right
to a benefit under the Plan except in accordance with the terms of the
Plan.  Establishment of the Plan shall not be construed to give any
Participant the right to be retained in the service of the Company.

     Section 8.4  No interest of any person or entity in, or right to
receive a benefit under, the Plan shall be subject in any manner to sale,
transfer, assignment, pledge, attachment, garnishment, or other
alienation or encumbrance of any kind; nor may such interest or right to
receive a benefit be taken, either voluntarily or involuntarily, for the
satisfaction of the debts of, or other obligations or claims against,
such person or entity, including claims for alimony, support, separate
maintenance and claims in bankruptcy proceedings.

     Section 8.5  The Plan shall be construed and administered under the
laws of the State of Ohio.


     Section 8.6  If the actuarial value of any retirement benefit or
surviving spouse benefit is less than $3,500, the Company may pay the
actuarial value of such Benefit to the Participant or Surviving Spouse in
a single lump sum in lieu of any further benefit payments hereunder.

     Section 8.7  If any person entitled to a benefit payment under the
Plan is deemed by the Company to be incapable of personally receiving and
giving a valid receipt for such payment, then, unless and until claim
therefor shall have been made by a duly appointed guardian or other legal
representative of such person, the Company may provide for such payment
or any part thereof to be made to any other person or institution then
contributing toward or providing for the care and maintenance of such
person.  Any such payment shall be a payment for the account of such
person and a complete discharge of any liability of the Company and the
Plan therefor.

     Section 8.8  The Plan shall not be automatically terminated by a
transfer or sale of assets of the Company or by the merger or
consolidation of the Company into or with any other corporation or other
entity, but the Plan shall be continued after such sale, merger or
consolidation only if and to the extent that the transferee, purchaser or
successor entity agrees to continue the Plan.  In the event that the
Excess Plan is not continued by the transferee, purchaser or successor
entity, then the Plan shall terminate subject to the provisions of
Section 7.2.

     Section 8.9  Each Participant shall keep the Company informed of his
current address and the current address of his spouse.  The Company shall
not be obligated to search for the whereabouts of any person.  If the
location of a Participant is not made known to the Company within three
(3) years after the date on which payment of the Participant's retirement
benefit may first be made, payment may be made as though the Participant
had died at the end of the three-year period.  If, within one additional
year after such three-year period has elapsed, or, within three years
after the actual death of a Participant, the Company is unable to locate
any Surviving Spouse of the Participant, then the Company shall have no
further obligation to pay any benefit hereunder to such Participant or
Surviving Spouse or any other person and such benefit shall be
irrevocably forfeited.

     Section 8.10  Notwithstanding any of the preceding provisions of the
Plan, neither the Company nor any individual acting as an employee or
agent of the Company shall be liable to any Participant, former
Participant, Surviving Spouse or any other person for any claim, loss,
liability or expense incurred in connection with the Plan.


     Section 8.11  An assignment of part or all of a Participant's
Maximum Benefit pursuant to the terms of a QDRO shall not reduce the
Participant's Maximum Benefit for the purpose of determining the benefit,
if any, to be paid pursuant to the provisions of this Plan.

     Section 8.12  The benefits paid by this Plan shall not duplicate
benefits being paid or to be paid by the Retirement Plan or any
Supplemental Retirement Benefit the Participant or Participant's spouse
is receiving or may be entitled to receive.

     Section 8.13  In the event a Participant's claim for Plan benefits
is denied or in the event the Participant disputes the computation of the
benefit amount, the Participant shall be entitled to the same claims
appeal procedure that is available to the Participant under the terms of
the Retirement Plan.
