This Agreement replaces and supersedes any and all prior agreements between you and the Company regarding the engagement of you for your services by the Company, whether written or oral, formal or informal, including without limitation that certain letter agreement by and between you and the Company dated September 15, 1998 relating to your retirement and engagement as a consultant (the "Consulting Agreement"), which such Consulting Agreement shall be, as of the Effective Date terminated and of no further force or effect. In exchange for the mutual covenants set forth in this Agreement, including without limitation, your execution of the General Release of all Claims attached and incorporated herein as Exhibit 1, the Company agrees to the following: 1.

(iii) Any option or portion of an option that is, under its original terms, scheduled to Vest after December 31, 2003 is hereby forfeited, unless there occurs on or before that date a change of control (as defined by the terms of the original option) that would have accelerated the Vesting under its original terms, in which event the option shall be exercisable on or before April 1, 2004 to the extent its Vesting has been so accelerated.
