c.             You will be eligible to receive a 2006 bonus, in an amount determined by the Compensation Committee of the Board (the “Committee”) in accordance with the terms of the Company’s short term incentive plan, based on an individual performance factor for you of 100% and the Company performance factor as determined by the Committee.  You will not be eligible to receive any bonus in respect of the Company’s 2007 fiscal year.

d.             The Company shall provide you with continued coverage under the Company’s group health, vision and dental plans, on a basis that is substantially similar to the coverage provided to the Company’s senior executives (including, without limitation, with respect to the allocation of premium costs), for a period of six months following the Separation Date.  You may thereafter elect to continue your group health coverage pursuant to the Consolidated Omnibus Budget Reconciliation Act (“COBRA”).  In addition, the Company shall provide you with (i) financial counseling services for three months following the Separation Date and (ii) outplacement services suitable to your position for a period of one year following the Separation Date, at the Company’s sole cost.

5.             a.             You agree that you will not disparage or encourage or induce others to disparage any of the Company, its subsidiaries and affiliates, together with all of their respective past and present directors, managers, officers, shareholders, partners, employees, agents, attorneys, servants and clients and each of their predecessors, successors and assigns (collectively, the “Company Entities and Persons”).
