“As of March 1, 2006, the Employee will be eligible to continue coverage under the Company’s medical plan pursuant to the retiree medical coverage otherwise available to retiring employees who have attained a certain age and accrued a certain number of years of service. From March 1, 2006 to October 31, 2006, the Company shall pay on the Employee’s behalf the monthly contribution otherwise payable by the Employee under the terms of the retiree medical plan coverage, to the extent that such coverage is made available by the Company to its salaried employees at such time. In addition, from March 1, 2006 through October 31, 2006 (or, if earlier, the date the Employee’s spouse is no longer eligible for coverage under the terms of the retiree medical plan), the Company shall also pay on the Employee’s behalf the monthly premium otherwise payable by the Employee or the Employee’s spouse under the terms of the retiree medical plan to cover the Employee’s spouse, to the extent that such coverage is made available by the Company to its salaried employees at such time. Any other Employee out-of-pocket costs applicable under the retiree medical plan (including but not limited to deductibles, co-payments and co-insurances) shall be paid by the Employee and/or the Employee’s spouse pursuant to the terms of the retiree medical plan.

Section 5 — Early Termination of Employment Term on Disability or Death and

Section 13 — Automatic Renewal

These sections are deleted in their entirety.

Section 11 — Indemnification

The final sentence of Section 11 is deleted and replaced with:

“The defense and indemnification provisions contained in this Section 11 survive the termination of the Employment Term, and apply to all past, present, and future proceedings, whether known or unknown, including all civil or criminal proceedings, judgments, liabilities, claims, demands, damages, amounts paid in settlement, fines, penalties, punitive damages, actions, causes of action of any type or kind whatsoever, suits, losses, attorneys’ fees, costs, and expenses, arising out of, in connection with, or in any way related to his serving or having served as an officer or employee of, or as a consultant to, the Company or any predecessor thereof or at the request of the Company or any predecessor thereof.

The Company’s agreement to defend and indemnify the Employee, which is contained in this Section 11 of the Agreement, shall be construed as agreements independent of any other provision of this Agreement, and the existence of any claim or cause of action by the Company against the Employee, whether predicated on this Agreement or otherwise, including termination for cause, shall not constitute a defense to the enforcement by the Employee of this agreement by the Company to defend and indemnify the Employee.”
