The Employer may not add, delete, or replace any investment option identified
in this Service Agreement within 90 days of the Plan's adding the MFW.

The Employer understands that this MFW service is an investment selection of
a certain group of funds currently available for the Plan and that the funds
present in this MFW service change over time. The Employer understands that a
choice can be made at any time to change from the MFW service to another
investment platform (another window or a platform without a window
investment) offered by Fidelity and available to the Plan. The Employer will
always have the option to move to an investment platform of 15 Fidelity Funds
(not Select Funds) chosen from among those available to the Plan. The
Employer agrees that any change of investment platform will be effective as
soon as administratively feasible for Fidelity (after the Employer and
Fidelity have amended this agreement to reflect such change) and that the
Employer will communicate to participants the date and consequences of such
change.

The Employer hereby directs Fidelity to add new funds to the Permissible
Investments for the Plan as those funds are added to MFW service. Fidelity
shall always give the Employer at least 90 days notice of the date that new
fund(s) will become available through the MFW service an the Employer has
until 20 days before such date to direct Fidelity not to make any such new
fund or funds available for the Plan. The Employer understands that, since
this service is a package service and Fidelity is unable to customize this
package, the Employer's decision not to add certain fund(s) may mean that the
Plan is unable to remain on its current MFW service. If the Employer's
decisions make the Plan unable to remain on its current MFW service, the
Employer agrees to choose an entirely different investment platform (another
MFW service or a platform without a MFW service) for the Plan at least 10
business days before such new funds are to be added to the current MFW
service.

The Employer hereby directs Fidelity to remove from the Permissible
Investments for the Plan any funds being removed as a fund available under
the MFW service ("Non-MFW Funds"). Fidelity shall always give the Employer at
least 90 days notice of the date that a fund or funds will become Non-MFW
Funds. If the Employer decides to change any of the Core Permissible
Investments for the Plan, the Employer agrees that Fidelity may reassess the
Plan's fee structure and charge additional fees based upon the Core
Permissible Investments for the Plan resulting from the Employer's decision.
The Employer hereby directs Fidelity to exchange all balances present in the
any such Non-MFW funds, on the date such a Non-MFW Fund ceases to be a
Permissible Investment for the Plan, into the default investment for the
Plan.

The Employer agrees that any closure of a fund that is part of the MFW
service will be treated as a fund being removed from the MFW service pursuant
to the paragraph immediately preceding, except that Fidelity may adjust
notice timeframes as circumstances dictate. The Employer further agrees that
anytime a fund within the MFW service merges completely (thus ceasing to
exist) into a fund that is not currently a Permissible Investment under the
Plan, that such fund will be treated as if it was closing pursuant to the
previous sentence. Fidelity agrees that anytime two funds that are
Permissible Investments under the Plan merge, Fidelity will assist the
Employer with communicating in advance the consequences of the merger to its
Plan participants. The Employer agrees that when two Permissible Investments
merge Plan participants who do not act before the date of the merger will
have their account balances in each such fund combined in the resulting fund.
If a merger of two Permissible Investments will result in the Plan having one
less Core Permissible Investment, Fidelity agrees to give the Employer the
opportunity to remove the resulting fund from the MFW service and assign it
as a Core Permissible Investment. The Employer understands that the timing of
the merger of funds it outside of the control of the Trustee and that all
assistance to be provided the Employer will always be on a fest efforts
basis.

The Plan is intended to constitute a plan described in ERISA Section 404(c)
and regulations issued thereunder. The Employer shall not be relieved of
fiduciary responsibility for the selection and monitoring of all Permissible
Investments under the Plan, including any constituting part of the MFW.

AND FURTHER AGREE, that this Amendment shall be effective upon the date
indicated below and that the changes made by this Amendment are incorporated
into the Service Agreement and control over conflicting provisions of any
previously executed Service Agreement, or any amendment or addendum thereto.

This Amendment shall be effective July 10, 2002.

              Permissible Investments designated in the Service Agreement.

     2.  Section 2.01(a)(34) is added to the Basic Plan Document No. 07 as
         follows:

              "Permissible Investment" means the investments specified by the
              Employer as available for investment of assets of the Trust and
              agreed to by the Trustee.

     3.  Section 2.01(a)(35) is added to the Basic Plan Document No. 07 as
         follows:

              "Service Agreement" means the agreement between the Employer
              and the Prototype Sponsor (or an agent or affiliate of the
              Prototype Sponsor) relating to the provision of investment and
              other services to the Plan and shall include any addendum to
              the agreement and any other separate written agreement between
              the Employer and the Prototype Sponsor (or an agent or
              affiliate of the Prototype Sponsor) relating to the provision
              of services to the Plan.

     4.  All occurrences of "Section 1.14(b)" in the Basic Plan Document No.
         07 will be replaced with "the Service Agreement".

In witness whereof, the Employer has signed this instrument this 21, day of
June 2002.
