(b)                                 Termination of Employment.

(i)                                     Termination With Cause.  In the event that Optionee shall cease to be an employee of the Company or any of its subsidiaries (such event shall be referred to herein as Optionee’s “Termination”) for reason of Cause (as defined below), all unexercised Options (whether vested or unvested) shall terminate as of the date of such Termination.

(iii)                               Voluntary Termination for Material Breach; Termination Without Cause.  In the event of a Termination by Optionee of his employment for Material Breach (as defined below) or in the event of a Termination of Optionee by the Company without Cause, then (A) the portion of the Option that has not vested on or

2

prior to the date of such Termination shall terminate as of the date of such Termination; provided, however, that the unvested portion of the Option that would otherwise have vested at the end of the twelve (12) month period in which the Termination by Optionee of his employment or Termination of Optionee by the Company without Cause occurs, shall vest immediately on the date of such Termination on a pro rata basis according to the number of months in which Optionee has been employed during such 12-month period, and (B) the vested portion of the Option shall terminate as of the date that is twenty-four (24) months following the date of such Termination.

3.                                       Adjustments.  In the event that the outstanding securities of the class then subject to the Option are increased, decreased or exchanged for or converted into cash, property and/or a different number or kind of securities, or cash, property and/or securities are distributed in respect of such outstanding securities, in either case as a result of a reorganization, merger, consolidation, recapitalization, reclassification, dividend (other than a regular, quarterly cash dividend) or other distribution, stock split, reverse stock split or the like, or in the event that substantially all of the property and assets of the Company are sold, then, unless such event shall cause the Option to terminate pursuant to Section 2(c) hereof, the Committee shall make appropriate and proportionate adjustments in the number and type of shares or other securities or cash or other property that may thereafter be acquired upon the exercise of the Option; provided, however, that any such adjustments in the Option shall be made without changing the aggregate Exercise Price of the then unexercised portion of the Option.

4.                                       Exercise.  The Option shall be exercisable during Optionee’s lifetime only by Optionee or by his or her guardian or legal representative, and after Optionee’s death only by the person or entity entitled to do so under Optionee’s last will and testament or applicable intestate law.  The Option may only be exercised by the delivery to the Company of a written notice of such exercise, which notice shall specify the number of Option Shares to be purchased (the “Purchased Shares”) and the aggregate Exercise Price for such shares, together with payment in full of such aggregate Exercise Price in cash or by check payable to the Company; provided, however, that payment of such aggregate Exercise Price may instead be made, in
