(i) Death. The Executive's employment hereunder shall terminate upon his death. (ii) Disability. If the Executive has incurred a Disability, the Company may give the Executive written notice of its intention to terminate the Executive's employment.

(iii) Cause. The Company may terminate the Executive's employment hereunder for Cause. Any such termination for Cause may only be effected by the affirmative vote of a majority of the entire Board of Directors (other than the Executive and any other director who participated with the Executive in the alleged conduct), after written notice to the Executive and an opportunity to appear before the Board (with counsel) to respond to the allegations which are in such written notice, that the Executive has engaged in the alleged conduct and that in their good faith judgment such conduct warrants termination for Cause. (iv) Good Reason. The Executive may terminate his employment for Good Reason. (v) Without Cause. The Company may terminate the Executive's employment hereunder without Cause. (vi) Resignation without Good Reason. The Executive may resign his employment without Good Reason upon 90 days written notice to the Company. (b) Notice of Termination. Any termination of the Executive's employment by the Company or by the Executive under this Section 6 (other than termination pursuant to paragraph (a)(i)) shall be communicated by a written notice to the other party hereto indicating the specific termination provision in this Agreement relied upon, setting forth in reasonable detail any facts and circumstances claimed to provide a basis for termination of the Executive's employment under the provision so indicated, and specifying a Date of Termination which, except in the case of termination for Cause or Disability, shall be 6 7 at least thirty days following the date of such notice (a "Notice of Termination"); provided, the Company may pay out such notice period instead of employing the Executive. 7. Severance Payments. (a) Termination without Cause or for Good Reason. If the Executive's employment shall terminate without Cause (pursuant to Section 6(a)(v)) (which for this purpose shall include any termination by reason of the Company's non-extension or non-renewal of this Agreement beyond the Initial Term, Extension Term or otherwise), or for Good Reason (pursuant to Section 6(a)(iv)), and subject to the receipt of mutual releases in form reasonably acceptable to the parties, the Company shall (i) pay to the Executive, in a lump sum cash payment as soon as practicable following the Date of Termination, or, in its discretion, in monthly installments during the applicable term described in Section (9)(a), the prorated portion of the Bonus to which he would otherwise be entitled for the year of termination and an amount equal to the sum of two times (A) his then current rate of Annual Base Salary and (B) the amount of his Deemed Bonus for the year of termination; provided, however, that on or after a Change in Control, such amount shall be three times the sum of his current rate of Annual Base Salary plus Deemed Bonus, (ii) except as otherwise provided in Section 5(c)(i)(C), cause to become vested that number, if any, of his then unvested Base Options as would have been vested as of the Date of Termination if all of his Base Options had been subject to vesting in equal installments on the first three December 31's that follow the date of grant; provided, however, that if the Date of Termination is on or prior to December 31, 1999, one-third of the Base Options shall become exercisable, (iii) if the Closing Price on the day prior to the Date of Termination represents at least a 27.5% annual compound rate of appreciation from the Closing Price on the Effective Date, then (A) cause to become vested that number, if any, of his then unvested Incentive Options described in Section 5(c)(iii)(A) as would have been vested as of the Date of Termination if all of such Incentive Options had been subject to vesting in equal installments on the first three December 31's that follow the date of grant, and (B) cause to become vested that number, if any, of his then unvested Incentive Options described in Section 5(c)(iii)(B) as would have been vested as of the Date of Termination if all of such Incentive Options had been subject to vesting in equal installments on the first five December 31's that follow the date of grant. (iv) The Company shall also continue to provide the Executive with all employee benefits and perquisites which he was participating in or receiving at the time of the Termination of Employment (or if greater, at the end of the prior year) until the earlier of two years (three years if after a Change of Control) or his receipt of comparable benefits from a successor employer. If such benefits cannot be provided under the Company's programs, such benefits and perquisites will be provided on an individual basis to the Executive such that his after-tax costs will be no greater than the costs for such benefits and perquisites under the Company's programs. (b) Termination by Reason of Disability or Death. If the Executive's employment shall terminate by reason of his Disability (pursuant to Section 6(a)(ii)) or death (pursuant to Section 6(a)(i)), and subject to the receipt of mutual releases in form reasonably acceptable to the parties, the Company shall cause the Options to vest as they would have under paragraphs 7(a)(ii) and (iii) above if the words "the December 31 next following" were inserted in such subsections immediately prior to "the Date of Termination." (c) Voluntary Resignation without Good Reason. If the Executive's employment shall terminate by reason of his voluntary resignation without Good Reason (pursuant to Section 6(a)(vi), and so long as the Company would not at such time have had grounds to terminate the Executive's employment for Cause), the Company shall cause his Base Options to become vested at the greater of the actual rate of vesting or the rate of equal installments on the first five December 31's that follow the date of grant. 7 8 (d) Survival. The expiration or termination of the Term shall not impair the rights or obligations of any party hereto which shall have accrued hereunder prior to such expiration. (e) Mitigation of Damages. In the event of any termination of the Executive's employment by the Company, the Executive shall not be required to seek other employment to mitigate damages, and any income earned by the Executive from other employment or self-employment shall not be offset against any obligations of the Company to the Executive under this Agreement. Except for any action or claim to enforce the provisions of the promissory note or the agreement effectuating the pledge, each as described in Section 5(d)(ii)(B), the Company's obligations hereunder and the Executive's rights to payment shall not be subject to any right of set-off, counterclaim or other deduction by the Company not in the nature of customary withholding, other than in any judicial proceeding or arbitration. 8. Parachute Payments. (a) If it is determined (as hereafter provided) that by reason of any payment or Option vesting occurring pursuant to the terms of this Agreement (or otherwise under any other agreement, plan or program) upon a Change in Control (collectively a "Payment") the Executive would be subject to the excise tax imposed by Code Section 4999 (the "Parachute Tax"), then the Executive shall be entitled to receive an additional payment or payments (a "Gross-Up Payment") in an amount such that, after payment by the Executive of all taxes (including any Parachute Tax) imposed upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the Parachute Tax imposed upon the Payment. (b) Subject to the provisions of Section 8(a) hereof, all determinations required to be made under this Section 8, including whether a Parachute Tax is payable by the Executive and the amount of such Parachute Tax and whether a Gross-Up Payment is required and the amount of such Gross-Up Payment, shall be made by the nationally recognized firm of certified public accountants (the "Accounting Firm") used by the Company prior to the Change in Control (or, if such Accounting Firm declines to serve, the Accounting Firm shall be a nationally recognized firm of certified public accountants selected by the Executive). The Accounting Firm shall be directed by the Company or the Executive to submit its preliminary determination and detailed supporting calculations to both the Company and the Executive within 15 calendar days after the determination date, if applicable, and any other such time or times as may be requested by the Company or the Executive. If the Accounting Firm determines that any Parachute Tax is payable by the Executive, the Company shall pay the required Gross-Up Payment to, or for the benefit of, the Executive within five business days after receipt of such determination and calculations. If the Accounting Firm determines that no Parachute Tax is payable by the Executive, it shall, at the same time as it makes such determination, furnish the Executive with an opinion that he has substantial authority not to report any Parachute Tax on his federal tax return. Any good faith determination by the Accounting Firm as to the amount of the Gross-Up Payment shall be binding upon the Company and the Executive absent a contrary determination by the Internal Revenue Service or a court of competent jurisdiction; provided, however, that no such determination shall eliminate or reduce the Company's obligation to provide any Gross-Up Payments that shall be due as a result of such contrary determination. As a result of the uncertainty in the application of Code Section 4999 at the time of any determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments that will not have been made by the Company should have been made (an "Underpayment"), consistent with the calculations required to be made hereunder. In the event that the Company exhausts or fails to pursue its remedies pursuant to Section 8(f) hereof and the Executive thereafter is required to make a payment of any Parachute Tax, the Executive shall direct the Accounting Firm to determine the amount of the Underpayment that has occurred and to submit its determination and detailed supporting calculations to both the Company and the Executive as promptly as possible. Any such Underpayment shall be promptly paid by the Company to, or for the benefit of, the Executive within five business days after receipt of such determination and calculations. (c) The Company and the Executive shall each provide the Accounting Firm access to and copies of any books, records and documents in the possession of the Company or the Executive, as the case may 8 9 be, reasonably requested by the Accounting Firm, and otherwise cooperate with the Accounting Firm in connection with the preparation and issuance of the determination contemplated by Section 8(b) hereof. (d) The federal tax returns filed by the Executive (or any filing made by a consolidated tax group which includes the Company) shall be prepared and filed on a basis consistent with the determination of the Accounting Firm with respect to the Parachute Tax payable by the Executive. The Executive shall make proper payment of the amount of any Parachute Tax, and at the request of the Company, provide to the Company true and correct copies (with any amendments) of his federal income tax return as filed with the Internal Revenue Service, and such other documents reasonably requested by the Company, evidencing such payment. If prior to the filing of the Executive's federal income tax return, the Accounting Firm determines in good faith that the amount of the Gross-Up Payment should be reduced, the Executive shall within five business days pay to the Company the amount of such reduction. (e) The fees and expenses of the Accounting Firm for its services in connection with the determinations and calculations contemplated by Sections 8(b) and (d) hereof shall be borne by the Company. If such fees and expenses are initially advanced by the Executive, the Company shall reimburse the Executive the full amount of such fees and expenses within five business days after receipt from the Executive of a statement therefor and reasonable evidence of his payment thereof. (f) In the event that the Internal Revenue Service claims that any payment or benefit received under this Agreement constitutes an "excess parachute payment" within the meaning of Code Section 280G(b)(1), the Executive shall notify the Company in writing of such claim. Such notification shall be given as soon as practicable but not later than 10 business days after the Executive is informed in writing of such claim and shall apprise the Company of the nature of such claim and the date on which such claim is requested to be paid. The Executive shall not pay such claim prior to the expiration of the 30 day period following the date on which the Executive gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Company notifies the Executive in writing prior to the expiration of such period that it desires to contest such claim, the Executive shall (i) give the Company any information reasonably requested by the Company relating to such claim; (ii) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company and reasonably satisfactory to the Executive; (iii) cooperate with the Company in good faith in order to effectively contest such claim; and (iv) permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear and pay directly all costs and expenses (including, but not limited to, additional interest and penalties and related legal, consulting or other similar fees) incurred in connection with such contest and shall indemnify and hold the Executive harmless, on an after-tax basis, for and against for any Parachute Tax or income tax or other tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses. (g) The Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct the Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner and the Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs the Executive to pay such claim and sue for a refund, the Company shall advance the amount of such payment to the Executive on an interest-free basis, and shall indemnify and hold the Executive harmless, on an after tax basis, from any Parachute Tax (or other tax including interest and penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance; and provided, further, that if the Executive is required to extend the statue of limitations to enable the Company to contest such claim, the Executive may limit this extension solely to such contested amount. The Company's control of the contest shall be limited to issues with respect to which a corporate deduction would be disallowed pursuant to Code 9 10 Section 280G and the Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority. In addition, no position may be taken nor any final resolution be agreed to by the Company without the Executive's consent if such position or resolution could reasonably be expected to adversely affect the Executive unrelated to matters covered hereto. (h) If, after the receipt by Executive of an amount advanced by the Company in connection with the contest of the Parachute Tax claim, the Executive receives any refund with respect to such claim, the Executive shall promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto); provided, however, if the amount of that refund exceeds the amount advanced by the Company the Executive may retain such excess.
