                  by the Economic Growth and Tax Relief Reconciliation Act of
                  2001 and Regulations and IRS Notice 2005-5 which authorizes
                  the elimination of mandatory single-sum distributions pursuant
                  to Code Section 411(a)(11) without violation of Code Section
                  411(d)(6).

         2.       Amendment. The plan is amended at Section 7.3(a)(i), (ii) and
                  (iii) to reduce the cash out limit under the plan to $1,000.

         3.       Effective Date. This Amendment shall be effective March 28,
                  2005.

         4.       Revised Pages. The Amendments reflected above are incorporated
                  in revised pages which shall be substituted for their
                  counterparts and the removed pages shall be attached to this
                  amendment.

         IN WITNESS WHEREOF, the Employer has caused this instrument to be
executed by a proper officer the day and year first above written.

                           (A) AMOUNT. The distribution does not exceed the
                  immediate and heavy financial need of the participant
                  (including amounts necessary to pay any federal, state, or
                  local income taxes or penalties reasonably expected to result
                  from the distribution);

                           (B) DISTRIBUTION AND LOANS. The participant has
                  obtained all distributions (other than for hardship) and all
                  nontaxable loans currently available under all plans
                  maintained by the Employer (or Affiliated Employer);

                           (C) SUSPENSION. The participant's Participant
                  Contributions to this Plan and all other qualified and
                  nonqualified plans of deferred compensation (other than health
                  or welfare benefit plans) maintained by the Employer (or
                  Affiliated Employer) are required to be suspended for twelve
                  (12) months (six (6) months, effective January 1, 2002) after
                  receipt of the Hardship distribution; and

                           (D) REDUCED ELECTIVE. Under all plans maintained by
                  the Employer (or Affiliated Employer), the participant may not
                  make Elective Contributions for the taxable year immediately
                  following the taxable year of the hardship distribution in
                  excess of the applicable limit under Code Section 402(g) for
                  that next taxable year less the amount of the participant's
                  Salary Deferred Contributions for the taxable year of the
                  hardship distribution.

         7.3      METHOD OF PAYMENT. Effective on the first day of the 1987 Plan
Year, January 1, 1987, except as provided, payments from a participant's
Accounts at or after a Distributive Event shall be made by a single payment
within one (1) taxable year of the recipient.

         (a)      CASH-OUT. The Participant's consent is not required with
respect to the following distributions.

                  (i) ON OR AFTER MARCH 28, 2005. For distributions made on or
         after March 28, 2005, if a Participant's Vested Account Balance is
         $1,000 or less and the Participant's employment terminates for any
         reason other than death, the Participant's Vested Account Balance shall
         be distributed as soon as administratively feasible following the end
         of the Plan Year in which the Participant's employment terminates. The
         Participant may elect earlier payment. To the extent consistent with
         Regulations and other guidance, the Participant's Vested Account
         Balance shall be determined without regard to the portion of the
         account balance that is attributable to rollovers and direct transfers,
         including earnings, from an eligible plan under Code Sections 402(c),
         403(a)(4), 403(b)(8), 408(d)(3)(A)(ii) and 457(e)(16).

                  larger amount as may be specified in Code Section
                  411(a)(11)(A)) or less. Effective January 1, 2002, the value
                  of a participant's Vested Account Balance shall be determined
                  without regard to that portion of the Account Balance that is
                  attributable to rollover contributions (and allocable
                  earnings) within the meaning of Code Sections 402(c),
                  403(a)(4), 403(b)(8), 408(d)(3)(A)(ii) and 457(e)(16).

                  Balance is $5,000 or less unless the distribution is one of a
                  series of scheduled periodic payments and the participant's
                  consent was required at the time the initial payment was made.

                             (C) BEFORE MARCH 22, 1999. A distribution made
                  before March 22, 1999, when the participant's Vested Account
                  Balance, including any earlier distribution, is $5,000 or
                  less.

                  (iii)      BEFORE AUGUST 6, 1997. For Plan Years beginning
         before August 6, 1997, a distribution when the participant's Vested
         Account Balance, including any earlier distribution, is $3,500 or less.

         (b)      TERMINATION. On recognition by the Employer of termination of
the Plan, Elective Contributions and Qualifying Accounts must be transferred to
any other defined contribution plan maintained by the Employer or a member of a
controlled group including the Employer (other than a Code Section 4975(e)(7)
employee stock ownership plan).

         (c)      STOCK. Except as otherwise provided, all distributions shall
be in whole shares of Stock if and to the extent the distribution is from an

distributed in cash.

                  (i) ELECTION AGAINST STOCK. Any participant or other payee may
         elect on the appropriate form to receive in cash all or part of the
         portion of a distribution which would otherwise be made in Stock.
