               whole shares of the common stock held in any Fund designated to
               invest in securities of the Employer or Predecessor Employer (or
               securities of any unrelated company that may be distributed with
               respect to the securities of the Employer or Predecessor Employer
               by reason of a spin-off or otherwise), and attributable to his or
               her Account as of the Valuation Date coincident with or preceding
               the record date shall be voted at all stockholders' meetings. The
               Funding Agent shall confidentially receive and tally the
               instructions from Members. The Funding Agent shall not disclose
               such instructions to the Employer or the Plan Administrator or
               any officer, director or Affiliate. Any stock for which a signed
               voting direction instrument is not received from the Member, or
               is not subject to being received, shall be voted by the Funding
               Agent in the same proportion as the stock for which signed
               voting-direction instruments are received as to the matter to be
               voted upon.

               12.2 TENDER OFFERS. A Member may direct the Funding Agent in
               writing how to respond to a tender or exchange offer for any or
               all whole securities held in any Fund designated to invest in
               securities of the Employer (or securities of any unrelated
               company that may be distributed with respect to the securities of
               the Employer or Predecessor Employer by reason of a spin-off or
               otherwise), and attributable to his or her Account as of the
               Valuation Date preceding, or coincident with, the offer. A
               Member's instructions hereunder shall be confidential and shall
               not be disclosed to the Employer or the Plan Administrator. The
               Plan Administrator shall notify each Member and timely distribute
               or cause to be distributed to him or her such information as will
               be distributed to securityholders in connection with any such
               tender or exchange offer. The Funding Agent shall confidentially
               receive instructions from Members and shall not disclose such
               instructions to the Employer or the Plan Administrator. Upon
               receipt of such instructions, the Funding Agent shall tender such
               securities as and to the extent so instructed. If the Funding
               Agent shall not receive instructions with respect to a Member
               regarding any such tender or exchange offer for such shares of
               stock (or shall receive instructions not to tender or exchange
               such shares), the Funding Agent shall have no discretion in such
               matter and shall take no action with respect thereto. Any shares
               for which instructions are not subject to being received shall be
               tendered by the Funding Agent only in the same proportion as the
               stock for which instructions to tender are received. Any
               securities received by the Funding Agent as a result of a tender
               of securities shall be held, and any cash so received, shall be
               invested in short-term investments for the Account of the Member
               with respect to whom shares were tendered pending any
               reinvestment by the Funding Agent consistent with the purpose of
               the Plan."

               "13.3 INDEMNIFICATION. In each case in which a director, officer
               or Employee of an Employer is or was serving at the request of
               the Board as the Plan Administrator or as a member of a committee
               authorized to act on behalf of the Plan Administrator, the
               Employer, by the adoption of this Plan, indemnifies and holds
               such person or the members of such committee (including their
               delegees), jointly and severally, harmless from the effects and
               consequences of their acts, omissions, and conduct in their
               official capacities, except to the extent that the effects and
               consequences result from their own willful misconduct or gross
               negligence in the performance of their duties. The foregoing
               right of indemnification will not be exclusive of other rights to
               which each such individual may be entitled by any contract or
               other instrument or as a matter of law."

        8. Section 13.5 of the Plan is hereby amended by deleting the first
sentence thereof.

        9. Section 15.1 of the Plan is hereby amended to read in its entirety as

               Employee Benefits Committee appointed by the Board the right at


                                      -3-

<PAGE>


               any time to amend the Plan, provided that any such amendment
               could not significantly affect the cost of the Plan. If an
               amendment could significantly affect the cost of the Plan, then
               such amendment may only be adopted by the Board. Any amendment
               adopted by the Employee Benefits Committee or the Board shall be
               binding upon each Employer. Except as provided in Section 17.2,
               no such amendment(s) shall have the effect of reverting to the
               Employer the whole or any part of the principal or income for
               purposes other than for the exclusive benefit of Members or
               Beneficiaries at any time prior to the satisfaction of all the
               liabilities under the Plan with respect to such persons. No
               amendment shall reduce a Member's Account balance on the
               effective date of the Plan amendment or eliminate an optional
               form of benefit under the Plan with respect to the Member's
               Account balance on the date of the amendment."
