3

(e)                                   Cause .  Subject to the notification provisions of Section 8(f) below, Executive’s employment hereunder may be terminated by the Company for Cause.  For purposes of this Agreement, the term “Cause” shall be limited to (i) willful misconduct by Executive with regard to the Company which has a material adverse effect on the Company; (ii) the willful refusal of Executive to attempt to follow the proper written direction of the Board, provided that the foregoing refusal shall not be “Cause” if Executive in good faith believes that such direction is illegal, unethical or immoral and promptly so notifies the Board; (iii) substantial and continuing willful refusal by the Executive to attempt to perform the duties required of him hereunder (other than any such failure resulting from incapacity due to physical or mental illness) after a written demand for substantial performance is delivered to the Executive by the Board which specifically identifies the manner in which it is believed that the Executive has substantially and continually refused to attempt to perform his duties hereunder; or (iv) the Executive being convicted of a felony (other than a felony involving a traffic violation or as a result of vicarious liability).  For purposes of this paragraph, no act, or failure to act, on Executive’s part shall be considered “willful” unless done or omitted to be done, by him not in good faith and without reasonable belief that his action or omission was in the best interests of the Company.  A notice by the Company of a non-renewal of the Employment Term pursuant to Section 1 hereof shall be deemed an involuntary termination of Executive by the Company without Cause as of the end of the then Employment Term, but Executive may terminate at any time after the receipt of such notice and shall be treated as if he was terminated without Cause as of such date.

(f)                                     Notice of Termination for Cause .  A Notice of Termination for Cause shall mean a notice that shall indicate the specific termination provision in Section 8(e) relied upon and shall set forth in reasonable detail the facts and circumstances which provide for a basis for Termination for Cause.  Further, a Notification for Cause shall be required to include a copy of a resolution duly adopted by at least two-thirds (2/3) of the entire membership of the Board at a meeting of the Board which was called for the purpose of considering such termination and which Executive and his representative had the right to attend and address the Board, finding that, in the good faith of the Board, Executive engaged in conduct set forth in the definition of Cause herein and specifying the particulars thereof in reasonable detail.  The date of termination for a Termination for Cause shall be the date indicated in the Notice of Termination.  Any purported Termination for Cause which is held by a court not to have been based on the grounds set forth in this Agreement or not to have followed the procedures set forth in this Agreement shall be deemed a Termination by the Company without Cause.

9.                                        Consequences of Termination of Employment .

(a)                                   Death .  If, Executive’s employment is terminated by reason of Executive’s death, the employment period under this Agreement shall terminate without further obligations to the Executive’s legal representatives under this Agreement except for:  (i) any compensation earned but not yet paid, including and without limitation, any bonus if declared or earned but not yet paid for a completed fiscal year, any amount of Base Salary earned but unpaid, any accrued vacation pay payable pursuant to the Company’s policies, and any unreimbursed business expenses payable pursuant to Section 7 (collectively “ Accrued Amounts ”), which amounts shall be promptly paid in a lump sum to Executive’s estate; (ii) any other amounts or benefits owing to the Executive under the then applicable employee benefit plans, long term incentive plans or equity plans and programs of the Company which shall be paid or treated in accordance with Section 4(c) hereof with regard to the May 2001 Stock Options and otherwise in accordance with the terms of such plans and programs; (iii) continuation, for twelve (12) months following the date of death, of Executive’s health benefits for Executive’s dependents at the same level and cost as if Executive was an employee of the Company; and (iv) if a bonus plan is in place, the product of (x) the target annual bonus for the fiscal year of Executive’s death, multiplied by (y) a fraction, the numerator of which is the number of days of the current fiscal year during which Executive

was employed by the Company, and the denominator of which is 365, which bonus shall be paid when bonuses for such period are paid to the other executives.

(b)                                  Disability .  If Executive’s employment is terminated by reason of Executive’s Disability, Executive shall be entitled to receive the payments and benefits to which his representatives would be entitled in the event of a termination of employment by reason of his death plus Executive shall be entitled to continuation, for twelve (12) months following such termination of employment, of group life and disability insurance benefits as if Executive was an active employee of the Company.

(c)                                   Termination by Executive for Good Reason or Termination by the Company without Cause .  If Executive terminates his employment hereunder for Good Reason during the Employment Term or Executive’s employment with the Company is terminated by the Company without Cause, then:

(i) if such termination occurs on a date that does not fall within the Protection Period (as defined below), Executive shall be entitled to receive, (A) over a period of twenty-four (24) months after such termination (except as provided below), an amount equal to two (2) times the sum of his Base Salary and target bonus, if any, for the year in which such termination occurs (provided, however, in the event that the Base Salary or target bonus, if any, has been decreased in the twelve (12) months prior to the termination, the amount to be used shall be the highest Base Salary and target bonus, if any, during such twelve (12) month period); (B) any Accrued Amounts at the date of termination; (C) any other amounts or benefits owing to Executive under the then applicable employee benefit, long term incentive or equity plans and programs of the Company, which shall be paid or treated in accordance with Section 4(c) hereof with regard to the May 2001 Stock Options and otherwise in accordance with the terms of such plans and programs, except that (1) the portion of each outstanding option to acquire shares of Common Stock held by Executive that would have otherwise vested with the passage of time during the one-year period immediately following the Executive’s termination of employment had the Executive remained employed with the Company during such one-year period shall be treated as immediately vested as of the date of such termination, (2) each outstanding vested option to acquire shares of Common Stock held by Executive as of the date of such termination (taking into account the additional vesting described in the preceding clause (1)) shall remain exercisable until the earlier of (x) the expiration of such option’s original term or (y) 18 months following the date of termination and (3) with respect to each outstanding grant of shares of restricted Common Stock held by Executive, such grant shall be deemed to be vested with respect to a number of shares determined as the product of (I) the total number of shares subject to such grant and (II) the quotient obtained by dividing (aa) the number of days in the relevant restricted period that the Executive was employed with the Company (assuming for such purpose that the Executive remained employed with the Company for the one-year period immediately following the Executive’s termination of employment) by (bb) the number of days in the relevant restricted period, but only to the extent that the application of this clause (3) would result in more shares being vested than would otherwise be vested under the terms of such plans and programs and applicable award agreements; (D) continuation, for two years following such termination of employment, of group health, life and disability insurance benefits as if Executive was an employee of the Company; and (E) if a bonus plan is in place, the product of (x) the target annual bonus for the fiscal year of Executive’s termination, multiplied by (y) a fraction, the numerator of which is the number of days of the current fiscal year during which Executive was employed by the Company, and the denominator of which is 365, which bonus shall be paid when bonuses for such period are paid to the other executives; and

(ii) if such termination occurs during the period (the “ Protection Period ”) commencing on the date of a Change in Control (as defined in Section 11(a)) and ending on the third anniversary of such Change in Control, Executive shall be entitled to receive, (A) a lump sum cash payment in an amount equal to three (3) times the sum of his Base Salary and target bonus, if any, for the year in which such termination occurs (provided, however, in the event that the Base Salary or target bonus, if any, has been decreased in the twelve (12) months prior to the termination, the amount to be used shall be the highest Base Salary and target bonus, if

5

any, during such twelve (12) month period); (B) any Accrued Amounts at the date of termination; (C) any other amounts or benefits owing to Executive under the then applicable employee benefit, long term incentive or equity plans and programs of the Company, which shall be paid or treated in accordance with the terms of such plans and programs, except that (1) each outstanding option to acquire shares of Common Stock held by Executive as of the date of such termination shall become immediately fully vested and remain exercisable until the earlier of (x) the expiration of such option’s original term or (y) 36 months following the date of termination and (2) each outstanding share of restricted Common Stock held by Executive shall be immediately fully vested as of the date of such termination; (D) continuation, for three years following such termination of employment, of group health, life and disability insurance benefits as if Executive was an employee of the Company; and (E) if a bonus plan is in place, the product of (x) the target annual bonus for the fiscal year of Executive’s termination, multiplied by (y) a fraction, the numerator of which is the number of days of the current fiscal year during which Executive was employed by the Company, and the denominator of which is 365, which bonus shall be paid when bonuses for such period are paid to the other executives.

To the extent that any portion of the amount payable pursuant to clause (i)(A) of this Section 9(c) would be subject to the additional 20% tax imposed under Section 409A of the Code (the “ 409A Affected Amount ”), the parties shall negotiate in good faith an alternative arrangement that will provide Executive with payments that are equivalent in value to the value of the 409A Affected Amount but would not be subject to such additional 20% tax; provided , however , that to the extent the “short-term deferral” exception as promulgated in Internal Revenue Service Notice 2005-1 is still applicable, the Company shall pay the portion of the 409A Affected Amount otherwise due after the latest date it could be paid and still maintain the benefit of such “short-term deferral” exception in the form of a lump sum cash payment, on the latest possible date permitted pursuant to such “short-term deferral” exception that would avoid such additional 20% tax, in an amount equal to the present value of the 409A Affected Amount on such payment date, with such present value determined based on an interest rate equal to the Company’s then applicable cost of short-term borrowing.  In addition, to the extent that any extension, pursuant to clause (i)(C)(2) or clause (ii)(C)(1) of this Section 9(c), of the period of exercisability of any outstanding option to acquire shares of Common Stock would result in the imposition on Executive of the additional 20% tax under Section 409A of the Code, such extension shall not apply without the consent of the Executive.

(d)                                  Termination with Cause or Voluntary Resignation without G
