                       SECTION THREE - PROGRAM BENEFIT

3.01  Account.  As of the Effective Date, the Committee will establish an
Account in the Executive's name.  Subject to the terms of this Program, the
Account will:

      [1] Be credited with the amount described in Section 3.02;

      [2] Periodically be adjusted to reflect Earnings as described in
          Section 3.03;

      [3] Be fully vested and nonforfeitable in accordance with Section
          4.01; and

      [4] Be distributed as provided in Sections 4.02, 4.03 and/or 4.04.

3.02  Contributions Credited to Account.  The Company will credit the
Executive's Account with amounts deferred by the Executive pursuant to the
Employment Agreement which are compensation payable to the Executive which
are reasonably anticipated to exceed the limitation or deductible
compensation under Code Section 162(m) for a particular Program Year.  Such
amount shall be calculated as soon as administratively practicable after
the end of the Program Year and deemed contributed to the Executive's
Account as of such date.

3.03  Earnings Credited to Account.  Earnings will be credited on an annual
basis in accordance with the rate or method defined in Section 1.08.  Such
crediting will occur on the last day of the applicable period based on the
Account balance at such time.

               SECTION FOUR - DISTRIBUTION OF PROGRAM BENEFITS

4.01  Vesting.  All amounts allocated to the Executive's Account will be
fully vested and nonforfeitable at all times.

4.02  Time and Form of Payment.  Subject to this section and the terms of
this Program, the Executive's Account balance will be distributed to the
Executive in a single lump sum payment in cash as soon as administratively
feasible following the January 15th of the first calendar beginning after
the Executive's Termination of Employment.

Notwithstanding the foregoing, to the extent the Executive is a "specified
employee" within the meaning of Code Section 409A, such payment may not
commence for at least six (6) months following the Executive's Termination
of Employment or in accordance with any such other time restrictions
imposed by Code Section 409A and any regulations or guidance thereunder.

4.03  Unforeseeable Emergency.  Upon determination of an Unforeseeable
Emergency, the Executive may receive a distribution from the Program.  The
Executive must describe the nature and extent of the Unforeseeable
Emergency.  If an event constitutes an Unforeseeable Emergency and also
qualifies for an in-service hardship withdrawal under any tax-qualified
retirement plan maintained by the Corporation (or any other Group member)
and in which the Executive participates, the Executive may not withdraw any
amounts from the tax-qualified plan until he first exhausts amounts
available under this Program.  A distribution based on an


                                      4



Unforeseeable Emergency will be limited to the amount reasonably necessary
to satisfy the emergency need (which must include amounts necessary to pay
any Federal, State or Local income taxes or penalties reasonably
anticipated to result from the distribution.)

4.04  Special Distributions.

      [1]  Employment Taxes.  In accordance with Section 409A and the
regulations and guidance issued thereunder, an Executive may receive a
distribution under the Program (as an acceleration of the time or schedule
of a payment) to pay the Federal Insurance Contribution Act (FICA) tax
imposed under Code Sections 3101, 3121(a) and 3121(v)(2), income tax at
source on wages or corresponding withholding provisions of applicable
state, local or foreign tax laws as a result of the payment of the FICA
amount, and to pay the additional income tax at source on wages
attributable to the pyramiding Code Section 3401 wages and taxes.  The
total payment under this acceleration provision must not exceed the
aggregate of the FICA amount and the related income tax withholding.

      [2]  Income Inclusion Under Code Section 409A.  In accordance with
Section 409A and the regulations and guidance issued thereunder, an
Executive may receive a distribution under the Program (as an acceleration
of the time or schedule of a payment) at any time that the Program fails to
meet the requirements of Code Section 409A and the regulations thereunder.
The total payment may not exceed the amount required to be included in
income as a result of the failure to comply.

4.05  Limit on Excess Parachute Payments.  If the sum of the payments
described in this Program and those provided under any other plan, program
or agreement between the Executive and any Group member constitute "excess
parachute payments" as defined in Code Section 280G(b)(1), the Company will
either:

      [1]  Reimburse the Executive for the amount of any excise tax due
      under Code Section 4999, if this procedure provides the Executive with
      an after-tax amount that is larger than the after-tax amount produced
      under subsection 4.05[2]; or

      [2]  Reduce the amounts paid to the Executive under this Agreement so
      that his total "parachute payment" as defined in Code Section
      280G(b)(2)(A) under this and any other plan, program or agreement will
      be $1.00 less than the amount that would be an "excess parachute
      payment" if this procedure provides the Executive with an after-tax
      amount that is larger than the after-tax amount produced under
      subsection 4.05[1].

4.06  Delayed Payments.  In the event of a genuine dispute between the
Company and an Executive regarding the amount or timing of benefits under
the Program, a delay in the payment of amounts under this Program shall not
cause the Executive to violate Code Section 409A to the extent that such
delay satisfies the conditions set forth in Code Section 409A and
applicable regulations thereunder.



                                      5



                             SECTION FIVE - TAXES

5.01  Withholding for Taxes Due on Program Payments.  Regardless of any
other provision of this Program, any payment due under Section 4 will be
reduced by the amount of any federal, state and local income and wage taxes
the Company is required to withhold under any applicable law or regulation
from any payment made under Section 4.

5.02  Withholding for Taxes Due Before Payments Begin.  The Committee and
the Executive will agree on the method to be applied to pay the Executive's
portion of any employment, wage and other taxes imposed under any
applicable law or regulation on any Program benefit before that benefit is
paid to the Executive.  If the Committee and the Executive fail to agree on
the method to be applied, the Company will withhold the amount of the
Executive's liability from his other compensation.

5.03  Indemnification Under Code Section 409A.  Regardless of any other
provision of the Program, if the operation of the Program creates an excise
tax on amounts payable from the Program under Code Section 409A, the
Corporation will distribute an additional amount sufficient to ensure that
the Executive (or the Executive's beneficiary, if appropriate) retains an
amount as large as the amount he would have retained but for such
operation.  This undertaking applies to the effect of the excise taxes
arising under Code Section 409A as well as any other excise taxes that
might apply as a result of those taxes or this indemnification.

                         SECTION SIX - ADMINISTRATION

6.01  Appointment of Committee.  The Program will be administered by the
Committee.

6.02  Powers and Duties.  The Committee is fully empowered to exercise
complete discretion to administer the Program and to construe and apply all
of its provisions.

These powers and duties include:

      [1]  Subject to Section 6.07, resolving disputes that may arise with
      regard to the rights of the Executive and his legal representatives
      under the terms of the Program.  The Committee's decisions in these
      matters will be final in each case;

      [2]  Obtaining from the Company, each Group member and the Executive
      information that the Committee needs to determine the Executive's
      rights and benefits under the Program.  The Committee may rely
      conclusively upon any information furnished by the Company or the
      Executive;

      [3]  Compiling and maintaining all records it needs to administer the
      Program;

      [4]  Upon request, furnishing the Company with reasonable and
      appropriate reports of its administration of the Program;

      [5]  Authorizing the distribution of all benefits that are payable
      under the Program;


                                      6



      [6]  Engaging legal, administrative, actuarial, investment,
      accounting, consulting and other professional services that the
      Committee believes are necessary and appropriate;

      [7]  Adopting rules and regulations for the administration of the
      Program that are not inconsistent with the terms of the Program; and

      [8]  Doing and performing any other acts provided for in the Program.

Also, the Committee may delegate any of the powers and duties described in
subsections 6.02[2] through [4] to any other person or organization, as it
deems appropriate.

6.03  Actions by the Committee.  The Committee may act at a meeting, or in
writing without a meeting, by the vote or assent of a majority of its
members.  The Committee will appoint one of its members to act as secretary
to record all Committee action.  The Committee also may authorize one or
more of its members to execute papers and perform other ministerial duties
on behalf of the Committee.

6.04  Indemnification.  The Committee will be indemnified to the
fullest extent permitted by the Corporation's certificate of incorporation
and by-laws.

6.05  Conclusiveness of Action.  Subject to Section 6.07, any action on
matters within the discretion of the Committee will be conclusive, final
and binding upon the Executive and upon all persons claiming any rights
under the Program.

6.06  Payment of Expenses.

      [1]  Committee members will not be separately compensated for their
      services as Committee members.  However, the Company will reimburse
      Committee members for all appropriate expenses they incur while
      carrying out their Program duties.

      [2]  The compensation or fees of accountants, counsel and other
      specialists and any other costs of administering the Program will be
      paid by the Company.

6.07  Resolution of Disputes.

      [1]  Arbitration will be the exclusive means of resolving all disputes
      or questions arising out of or relating to this Program.  Any
      arbitration proceeding will be conducted before a panel of three
      arbitrators, one appointed by the Company, a second appointed by the
      Executive and a third appointed by those two arbitrators.  Any
      arbitration may be initiated by either the Company or the Executive by
      written notice to the other specifying the subject of the requested
      arbitration and appointing the initiating party's arbitrator.

      [2]  The arbitration will take place in Cincinnati, Ohio and will be
      conducted in accordance with the rules of the American Arbitration
      Association in effect when the arbitration begins.  Any determination
      or award made or approved by at least two of the arbitrators will be
      final and binding on the Company and the Executive.  Judgment upon


                                      7



      any award made in any arbitration may be entered and enforced in
      any court having competent jurisdiction.

      [3]  The costs of arbitration will be borne solely by the person by
      whom they are incurred.



                       SECTION SEVEN - PROGRAM AMENDMENT

The Company, by action of the Board, may modify, alter or amend the Program
at any time.  However, no amendment may affect the Executive's right to
receive the value of benefits accrued under the Program before the
effective date of that amendment unless the Executive agrees to that
reduction either in a separate written agreement or by voting, as a member
of the Board, for the reduction in benefits.  Notwithstanding the
foregoing, this Plan may be amended by action of the Committee and without
the consent of the Executive in order to comply with the provisions of Code
Section 409A.

                     SECTION EIGHT - TERMINATION OF PROGRAM

8.01 Right to Terminate.  The Company, by action of the Board, may
terminate the Program in whole or in part at any time.  However, no
termination may affect the Executive's right to receive the value of
benefits accrued under the Program before the effective date of that
termination unless the Executive agrees to that reduction either in a
separate written agreement or by voting, as a member of the Board, for the
reduction in benefits.

8.02  Automatic Termination.  This Program will automatically terminate
as of the date the Executive has received all of the benefits he is
entitled to receive under the terms of this document.

8.03  Merger and Consolidation.  If the Program is merged into or
consolidated with any other plan, the Executive will be entitled to a
benefit amount immediately after the merger or consolidation (determined as
if the surviving plan had then terminated) at least equal to the benefit
amount he had accrued immediately before the merger or consolidation
(determined as if the Program terminated immediately before that merger or
consolidation).

8.04  Successor Employer.  If the Company dissolves, reorganizes, merges
into or consolidates with another business entity, provision may be made by
which the successor will continue the Program, in which case the successor
will be substituted for the Company under the terms and provisions of this
Program.  The substitution of the successor for the Company will constitute
an assumption by the successor of all Program liabilities and the successor
will have all of the powers, duties and responsibilities of the Company
under the Program.

                            SECTION NINE - FUNDING

This Program constitutes an unfunded, unsecured promise by the Company to
pay only those


                                      8



benefits that are accrued by the Executive under the terms of the Program.
Neither the Company nor any Group member will segregate any assets into a
fund established exclusively to pay Program benefits unless the Company, in
its sole discretion, establishes a trust for this purpose.  Neither the
Company nor any Group member is liable for the payment of Program benefits
that are actually paid from a trust established for that purpose.  Also, the
Executive has only the rights of a general unsecured creditor and does not
have any interest in or right to any specific asset of the Company or any
Group member.  Nothing in this Program constitutes a guarantee by the
Company, any Group member or any other entity or person that the assets of
the Company, any Group member or any other entity will be sufficient to pay
Program benefits.

                         SECTION TEN - MISCELLANEOUS

10.01 Voluntary Program.  The Program is purely voluntary on the part
of the Company; neither the establishment of the Program nor any amendment
to it nor the creation of any fund or account nor the payment of any
benefits may be construed as giving any person [1] a legal or equitable
right against the Company, any Group member or the Committee other than
those specifically granted under the Program or conferred by affirmative
action of the Committee or the Company or any Group member in a manner that
is consistent with the terms and provisions of this Program or [2] the
right to be retained as an employee.

10.02 Nonalienation of Benefits.  The Executive's right to receive
Program benefits may not be assigned, transferred, pledged or encumbered,
including by will or by applicable laws of descent and distribution.  Any
attempt to assign, transfer, pledge, encumber or devise a Program benefit
will be null and void and of no legal effect.

10.03 Inability to Receive Benefits.  Any Program benefit payable to
the Executive after he is declared incompetent will be paid to the
guardian, conservator or other person legally charged with the care of his
person or estate.  Also, if the Committee, in its sole discretion,
concludes that the Executive is unable to manage his financial affairs, the
Committee may, but is not required to, direct the Company to distribute
Program benefits to any one or more of his spouse, lineal ascendants or
descendants or other close living relatives of the Executive who
demonstrates to the satisfaction of the Committee the propriety of those
distributions.  Any payment made under this Section will completely
discharge the Program's liability with respect to that payment.  The
Committee is not required to see to the application of any distribution
made to any person.

10.04 Inability to Locate Executive.  The Executive is obligated to
keep the Committee apprised of his current mailing address.  The
Committee's obligation to search for the Executive is limited to sending a
registered or certified letter to the Executive's last known address.  If
the Executive does not file a claim for benefits with the Committee, all
unpaid Program benefits will be forfeited no later than 12 months after
benefits are otherwise payable.

10.05 Limitation of Rights.  Nothing in the Program, expressed or
implied, is intended or may be construed as conferring upon or giving to
any person, firm or association (other than the Company, the Group and the
Executive) any right, remedy or claim under or by reason of this Program.


                                      9



10.06 Invalid Provision.  If any provision of this Program is held to
be illegal or invalid for any reason, the Program will be construed and
enforced as if the offending provision had not been included in the
Program.  However, that determination will not affect the legality or
validity of the remaining parts of this Program.

10.07 One Program.  This Program may be executed in any number of
counterparts, each of which will be deemed to be an original.

10.08 Governing Law.  The Program will be governed by and construed in
accordance with the laws of the United States and, to the extent
applicable, the laws of Ohio.

10.09 Coordination with other Programs.  The Executive's right to any
benefits accrued or payable under this Program will be determined solely by
reference to the terms of this Program document and will be unaffected by
any other document or agreement between the Executive and the Company or
any other Group member.

IN WITNESS WHEREOF, the undersigned authorized officer of the Company has
executed this Program to be effective as of May 18, 2006.
