attained his or her Vesting Date but before he or she has attained age 60 shall

The designated beneficiary of a Member who dies while employed by the Company

(a)
Except as otherwise provided in (b) below and in Sections 8.3 and 10.4, a
Member’s vested Benefit shall be paid to the Member, or in the case of a
Member’s death, to his or her designated beneficiary, in a single lump sum
payment determined in accordance with Section 8.2, as soon as administratively
feasible after his or her Termination Date, but no later than 30 days after such
date.

7

--------------------------------------------------------------------------------

(b)
With respect to a Member who has achieved his or her Vesting Date and whose
Termination Date occurs before he or she attains age 55, his or her vested
Benefit shall be paid to the Member, or in the event of his or her death prior
to such payment, to his or her designated beneficiary, as soon as
administratively feasible after his or her 55th birthday (or his or her date of
death, if sooner), but no later than 30 days after such date; provided however,
if such Member’s Termination Date is on account of a determination that he or
she is Permanently Disabled (as defined in Section 7.2), such Member’s Benefit
shall be paid as soon as administratively feasible after his or her Termination
Date, but no later than 30 days after such date.

(c)
Any designation of beneficiary shall be made by the Member on an election form
filed with the Administrator and may be changed by the Member at any time by
filing another election form containing the revised instructions. If no
beneficiary is designated or no designated beneficiary survives the Member,
payment shall be made to his or her estate.

8.2    Lump-Sum Valuation

(a)
The lump‑sum present value of a Member’s Benefit shall be the actuarial
equivalent of his or her Benefit payable as a single life annuity as set forth
in Section 6.2 or 6.3, as applicable.

(b)
Subject to the provisions of (c) below, the lump-sum present value of a Member’s
Benefit shall be determined by the enrolled actuary for the NCPP based upon
assumptions approved by the Administrator in its sole discretion. The
assumptions may be changed at any time, and from time to time, but any change
shall be valid only with respect to Termination Dates occurring twelve or more
months after the change is approved.

(c)
Unless otherwise directed by the Administrator, the lump sum present value of a
Member’s Benefit shall be calculated as of his or her Benefit Commencement Date
based upon: (i) the 60-month average of the Pension Benefit Guaranty Corporation
immediate annuity interest rate used in computing lump sums as in effect during
each of the 60 months preceding the month in which the Benefit Commencement Date
occurs; (ii) the age of the Member; (iii) the applicable mortality table in
effect under section 417(e)(3) of the Code; and (iv) the equivalent of the
amount otherwise payable as a lifetime annuity on the Member’s Benefit
Commencement Date. In the case of a payment to the designated beneficiary of a
deceased Member who had not attained age 55 at the time of his or her death, the
lump sum shall be based on the Member’s age as of the Benefit Commencement Date
and the present value of the deferred, actuarially reduced benefit that would
have been payable to the Member at age 55.

8.3    Six-Month Waiting Period

Notwithstanding any provision of the Plan to the contrary, with respect to any
Member who on his or her Termination Date is deemed to be a “specified employee”
within the

8

--------------------------------------------------------------------------------

meaning of Section 409A, his or her Benefit shall not be paid prior to the
earlier of: (i) the expiration of the six-month period measured from the date of
his or her “separation from service” (as defined in Section 409A) with the
Company, or (ii) his or her death. Such Member whose Benefit payment is so
delayed shall be entitled to interest on the delayed payment for such six-month
period (or shorter period as the case may be), accrued at the average prime rate
in effect during such period of delay, which shall be added to his or her
Benefit payable under the Plan. The average prime rate of interest for this
purpose shall be the average over such period of the daily prime rate of
interest published by the Fifth Third Bank, Cincinnati, Ohio or its successors.

ARTICLE 9: INTERPRETATION, AMENDMENT AND TERMINATION

9.1    Interpretation of the Plan

This document contains the terms of the Plan. However, the Administrator shall
have, and the Board expressly reserves to itself and its designate, the broadest
possible power to exercise its discretion to interpret the terms of this Plan
and to resolve any question regarding any person’s rights under the Plan. Any
such interpretation shall be final and binding upon a Member, the Member’s
spouse and heirs and subject to review only in accordance with Section 9.2.

9.2    Claims Procedure

Any Member or other person questioning the rights of any person under the Plan
shall submit such question in writing to the Administrator, or its designate,
for resolution. No person shall have any claim or cause of action for any
benefit under this Plan until the Administrator, or its designate, has responded
to such written claim, which response shall not be unreasonably delayed. Except
as to disputes described in Sections 10.2 and 10.4, it is the intent of the
Company, and each Member agrees as a condition of membership, that any judicial
review of any decision hereunder shall be limited to a determination of whether
the Administrator, or its designate, acted arbitrarily or capriciously, and that
any decision of the Administrator, or its designate shall be enforced unless the
action taken is found by a court of competent jurisdiction to have been
arbitrary or capricious. Disputes described in Sections 10.2 and 10.4 may be
resolved by binding arbitration, if mutually agreed by the Member and the
Administrator, or by litigation; and in either case such action may proceed
without the necessity of exhausting any other remedies that may be available
under this Plan.

9.3    Amendment or Termination of the Plan

The Board may, at any time, with or without notice to any person, amend or
terminate this Plan. With respect to any Member who has attained his or her
Vesting Date, and subject to Section 10.4, no such amendment or termination
shall directly or indirectly deprive such Member of all or any portion of his or
her vested Benefit or any right to receive his or her vested Benefit under the
terms of the Plan as in effect immediately before such amendment or termination.

9

--------------------------------------------------------------------------------

9.4    No Cause of Action

No Member shall have any right, claim or cause of action against any person or
entity to appeal the denial of a benefit by the Administrator except as provided
in Sections 9.1 and 9.2. In addition, no Member, and no person claiming by,
through or on behalf of a Member, shall have any claim to or cause of action for
any benefit under this Plan which might have been earned but for the amendment
or termination of the Plan, or the termination of the Member’s employment or the
removal of the Member from participation under this Plan.

ARTICLE 10: MISCELLANEOUS

10.1    Unsecured General Creditor

Any and all rights created under this Plan shall be unfunded and unsecured
contractual rights of the Members against the Company. The Company's obligation
under this Plan shall be a mere promise by the Company to make the benefit
payments described herein. Members shall have no legal or equitable right,
interest or other claim in any property or assets of the Company by reason of
the establishment of this Plan.

10.2    Obligations to the Company

If a Member becomes entitled to a distribution of benefits under this Plan, and
if at such time the Member has any outstanding debt, obligation or other
liability representing an amount certain owed to the Company, then the Company
may offset such amount against the amount of benefits otherwise distributable
under the Plan. Such determination shall be made by the Administrator.

10.3    Assignability

No Member shall have any right to anticipate, alienate, assign, sell, transfer,
pledge, encumber, attach, mortgage or otherwise hypothecate or convey in advance
of actual receipt the amounts, if any, payable hereunder. No part of the amounts
payable hereunder shall, prior to actual payment, be subject to seizure or
sequestration for the payment of any debts, judgments, alimony or separate
maintenance, nor shall any person have any other claim to any benefit payable
under this Plan as a result of a divorce or the Member's, or any other person's
bankruptcy or insolvency.

10.4    Forfeiture

Notwithstanding any provision in the Plan to the contrary, any Member terminated
for Cause shall forfeit all rights under this Plan. “Cause” means a willful
engaging in gross misconduct demonstrably injurious to the Company. “Willful”
means an act or omission in bad faith and without reasonable belief that such
act or omission was in the best interests of the Company. Any such determination
shall be made by the Board. Each Member shall be entitled to a statement of the
facts alleged as a basis for the Board's determination that a Member has been
terminated for Cause and shall be permitted an opportunity to present, in
person, for the Board's consideration, in such manner as the Board shall direct,
any facts or arguments on the Member’s behalf as the Member or his or her
representative may determine.

10

--------------------------------------------------------------------------------

10.5    Sale of Business

The sale as a going business of (i) the Company or (ii) substantially all of the
assets of the Company shall not be a termination of Service for the purpose of
establishing a Member’s right to receive benefits under this Plan.

10.6    Employment Not Guaranteed

The establishment of this Plan, a Member’s appointment as a Member of the Plan,
any provision of this Plan, or any action taken hereunder, shall not be or be
construed as a contract of employment for any definite term. The Company may
take any action related to a Member's employment without regard to the effect
such action has or may have on a Member’s rights hereunder.

10.7    Construction

The captions to the articles, sections and paragraphs of this Plan are for
convenience only and shall not control or affect the meaning or construction of
any of its provisions. Words in the masculine gender include the feminine, and
the singular includes the plural, and vice versa, unless qualified by the
context.

10.8    Validity

In the event any provision of this Plan is found by a court of competent
jurisdiction to be invalid, void or unenforceable, such provision shall be
stricken and the remaining provisions shall continue in full force and effect.

10.9    Applicable Law

This Plan is subject to interpretation under federal law and, to the extent
applicable, the law of the State of Ohio.
