                           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.
