2.      Section 7.01(b) is hereby amended in its entirety to read as follows:

                "(b)    Should neither limitation (1) or (2) in Section 7.01(a)
                        be met with respect to a Plan Year, the Committee,
                        subject to applicable law and regulations, shall cause
                        Excess Contributions and income allocable thereto to be
                        distributed in accordance with Section 7.01(d) no later
                        than 2 1/2 months following the end of any Plan Year to
                        Participants on whose behalf such Excess Contributions
                        were made for the current Plan Year.

                        A distribution of Excess Contributions and income, gains
                        and losses allocable thereto shall be made without
                        regard to any consent otherwise required under Section
                        10.01(c) or any other provision of the Plan. A
                        distribution pursuant to Section 7.01(b)(1) of Excess
                        Contributions and income, gains and losses allocable
                        thereto shall not be treated as a distribution for
                        purposes of determining whether the distribution
                        required by Section 10.06 is satisfied. Any distribution
                        under Section 7.01(b)(1) of less than the entire Excess
                        Contribution and income, gains and losses allocable
                        thereto shall be treated as a pro rata distribution of
                        Excess Contributions and income, gains and losses
                        allocable thereto. In no event shall Excess
                        Contributions for a Plan Year remain unallocated or be
                        allocated to a suspense account for allocation to one or
                        more employees in any future Plan Year."

3.      The first paragraph of Section 7.01(d) is hereby amended in its entirety

                        and any income or loss allocable to such Excess
                        Contribution shall be designated by the Committee as

                        Compensated Employees whose Accounts were credited with
                        Excess Contributions in the current Plan Year to
                        determine the aggregate amount of Excess Contributions
                        to be distributed, the Committee shall first determine
                        the aggregate dollar amount of the distribution as
                        follows:"

4.      Section 7.02(a) is hereby amended in its entirety to read as follows:

                                all Participants who are Non-Highly Compensated
                                Employees for the current Plan Year multiplied
                                by two, but not more than two percentage points
                                in excess of the Average Actual Contribution
                                Percentage of Participants who are Non-Highly
                                Compensated Employees.

                        provided in the Plan."

                "(a)    Each Employer shall contribute to the Trust, on behalf

                specified in a salary reduction agreement between the
                Participant and such Employer; provided, however, that such
                contribution for a Participant shall not exceed the limitations
                set forth in Code Section 402(g), or any successor thereto, for
                each Plan Year (including any other elective deferrals within
                the meaning of Code Section 402(g)(3) in the case of all other
                plans, contracts, or arrangements of the Employer)."

6.      A new Section 4.02A is hereby added to read as follows:

                "4.02A    CATCH-UP CONTRIBUTIONS.

                (a)     Eligibility. Effective for Plan Years beginning on or
                        after January 1, 2005, all Employees who are eligible to
                        make Elective Deferral Contributions under this Plan and
                        who are projected to have attained age 50 before the
                        close of the Plan Year shall be eligible to make
                        Catch-Up Contributions in accordance with, and subject
                        to the limitations of, Code Section 414(v).

                (b)     Election. In order to have Catch-Up Contributions made
                        on his or her behalf for a Plan Year, a Participant
                        shall direct that such Catch-Up Contributions be made
                        pursuant to a procedure prescribed by the Committee
                        whereby such Participant's annual Compensation shall be
                        reduced by a specified amount not to exceed the
                        limitations of Code Section 414(v), and whereby the
                        Employer agrees to contribute an identical amount on the



                        Participant's behalf to the Plan on a pre-tax basis
                        under this Section 4.02A.

                (c)     Application. Such Catch-Up Contributions shall not be
                        taken into account for purposes of the limitation set
                        forth in Section 5.02 hereof as well as the provisions
                        of the Plan implementing the required limitations of
                        Code Sections 402(g) and 415. The Plan shall not be
                        treated as failing to satisfy the provisions of the Plan
                        implementing the requirements of Code Sections
                        401(k)(3), 401(k)(11), 401(k)(12), 410(b), or 416, as
                        applicable, by reason of the making of such Catch-Up
                        Contributions.

                (d)     Classification; No Matching Contributions. For purposes
                        of this Plan, except as provided in this Section 4.02A,
                        Catch-Up Contributions shall be considered Elective
                        Deferral Contributions and shall be allocated to a
                        Participant's Elective Deferral Account. Notwithstanding
                        the foregoing, Catch-Up Contributions shall not be
                        considered Elective Deferral Contributions for purposes
                        of allocating Matching Contributions as provided in
                        Section 4.03(a) of this Plan."

7.      Subsection 7.01(e) is hereby amended in its entirety to read as follows:

                "(e)    The income, gain or loss allocable to distributed Excess
                        Contributions for the Plan Year for purposes of Section
                        4.01(b) is determined by multiplying the income for the
                        Plan Year allocable to Elective Deferral Contributions
                        by a fraction. The numerator of the fraction is the
                        Excess Contribution distributed to the Participant for
                        the Plan Year. The denominator of the fraction is the
                        total Account Balance of the Participant attributable to
                        Elective Deferral Contributions as of the end of the
                        Plan Year, reduced by the gain allocable to such total
                        amount for the Plan Year and increased by the loss
                        allocable to such total amount for the Plan Year."

8.      Subsection 7.02(f) is hereby amended in its entirety to read as follows:

                "(f)    The income, gain or loss allocable to distributed Excess
                        Aggregate Contributions for the Plan Year is determined
                        by multiplying the income for the Plan Year allocable to
                        Matching Contributions by a fraction. The numerator of
                        the fraction is the Excess Aggregate Contributions made
                        on behalf of the Participant for the Plan Year. The
                        denominator of the fraction is the total Account Balance
                        of the Participant attributable to Matching
                        Contributions as of the end of the Plan Year, reduced by
                        the gain allocable to such total amount for the Plan
                        Year and increased by the loss allocable to such total
                        amount for the Plan Year."



9.      In all other respects, the Plan shall remain unchanged by the Amendment.

        IN WITNESS WHEREOF, the Company has caused this instrument to be
executed the day and year first above written.
