         if that definition is more favorable for him than the definition in the
         first sentence of this Section 1.39.

                  (b) ELIGIBILITY. Section 3.01 of the Plan shall be amended to

         (3) COMMINGLING OF FUNDS. Temroc further agrees that the Committee, in
its sole discretion, may permit the funds contributed by them to be commingled
for purposes of investment with other funds in the Trust or to be maintained
separately.

         (4) AGREEMENT TO FURNISH INFORMATION. Temroc agrees to promptly furnish
all information required by the Committee and the Trustee with reference to its
employees who are eligible for the Plan, and to pay its contribution to the Plan

                     MERGER OF THE PRIOR PLAN INTO THE PLAN

         (1) MERGER OF PLAN. Effective July 1, 2001, the Prior Plan is merged

         (3) CONTRIBUTIONS. No contributions shall be made under the Prior Plan
with respect to any period after June 30, 2001.

         (4) QUALIFICATION A CONDITION PRECEDENT TO MERGER. The merger of the
Prior Plan into the Plan is contingent upon and subject to the express condition
precedent that the merger meets all statutory and regulatory requirements for
qualification of the Plan and the Prior Plan and their related trusts have at
all times in form and in operation maintained their qualified and exempt status.
In the event that this condition precedent is not satisfied the merger shall
fail retroactively for failure to meet the condition precedent and the portion

REVENUE CODE OF 1986. The merger of the Prior Plan into the Plan will comply
with sections 411(d)(6) and 414(l) of the Internal Revenue Code of 1986, as
amended (the "Code"). The distribution options available under the Prior Plan
shall be preserved in the Plan in accordance with section 411(d)(6) of the Code.
Each participant in the Prior Plan would (if the Prior Plan then terminated)
receive a benefit immediately after the merger equal to or greater than the
benefit he would have been entitled to receive immediately before the merger (if
the Prior Plan had then terminated).

         (6) SINGLE PLAN. Upon the merger of the Prior Plan into the Plan, the
Prior Plan and the Plan will be a single plan within the meaning of section
414(l) of the Code. All Prior Plan and Plan assets will be available to pay the
benefits of all participants in the Prior Plan and Plan.
