  (5) Section 5.1 of the Agreement is hereby amended by adding the following

read as follows: “As soon as practicable after the Company has knowledge that a
Change in Control is imminent, but no later than the day immediately preceding
the date of the Change in Control, the Company will deposit assets in such Trust
in an amount equal to the estimated aggregate Severance Benefits which may
become due to the Executive under Sections 3.3(a), (b), (c) and (d), and 5.1 and

liability for the relevant item, all legal fees, costs of litigation,
prejudgment interest, and other expenses incurred in good faith by the Executive
as a result of the Company’s refusal to provide the Severance Benefits to which

Company’s contesting the validity, enforceability, or interpretation of this
Agreement, or as a result of any conflict (including, without limitation,
conflicts related to the calculations under Section 5 hereof) between the
parties pertaining to this Agreement. The Company’s obligations under this

interest, and other expenses incurred on or before the date that is ten

costs of litigation, prejudgment interest, and other expenses for which
Executive is entitled to be reimbursed under this Article 8 in any calendar year
shall not affect Executive’s right to reimbursement of any expenses or in-kind
benefits to which Executive is entitled under this Agreement or any other
agreement to which Executive and the Company are parties.”

“Following a Qualifying Termination (as described in Section 3.2 herein), the
Executive will be reimbursed by the Company for the reasonable costs of all
outplacement services obtained by the Executive within a two (2) year period
after the Effective Date of Termination; provided, however, that the total

subject to liquidation, and (c) may not be exchanged for another benefit. The
amount of the costs of outplacement services for which Executive is entitled to
be reimbursed under this Article 9 in any calendar year shall not affect
Executive’s right to reimbursement of any expenses or in-kind benefits to which
Executive is entitled under this Agreement or any other agreement to which
Executive and the Company are parties.
