3

(3) Employer’s breach of any material term of this Agreement, which has a material adverse effect on Executive; or

In the cases set forth above in subparagraphs (1) through (3), the Executive must notify the Employer, within ninety (90) days of the date of occurrence of one of the events specified above, that such event has occurred and the Employer shall then have thirty (30) calendar days to remedy the situation under subparagraphs (1) and (3) above, and shall have five (5) calendar days to remedy the situation under subparagraph (2) above.

(ii) Employer may terminate Executive “Without Cause” by delivering to Executive written notice of such termination, and Executive may terminate this Agreement for “Good Reason” upon written notice. In the event Executive’s employment is terminated Without Cause by Employer or for Good Reason by Executive, Employer shall pay to Executive an amount equal to the remaining Base Compensation due to be paid to Executive through the end of the Initial Term or any Renewal Term, whichever is applicable, plus accrued vacation, plus Executive’s Proportionate Share of any awarded but unpaid Management Bonus for the prior calendar year and a Management Bonus for the year of termination calculated based on “Annualized Income before Bonuses and Income Taxes,” which shall mean Income before Bonuses and Income Taxes (as defined in Exhibit A) through the last day of the month during which termination occurs multiplied by a fraction the numerator of which is twelve (12) and the denominator of which is number of months during the Initial or any Renewal Term, as the case may be, which begin prior to date that Termination occurs and Executive’s Proportionate Share, together with Employee Benefits through the end of the Initial Term or any Renewal Term, whichever is applicable.

EXAMPLE : Assume that Executive’s employment is terminated on June 15 of the Initial Term and that Income before Bonuses and Income Taxes through June 30 of the Initial Term is Fifteen Million Dollars ($15,000,000). Therefore, Annualized Income before Bonuses and Income Taxes is Fifteen Million Dollars multiplied by 12/6 or Thirty Million Dollars ($30,000,000) and the Executive’s Proportionate Share is twelve percent (12%). Accordingly, Executive’s Management Bonus for the year of termination is determined as follows:

Annualized Income before Bonuses and Taxes—$30,000,000

Beginning Equity—$93,631,873

Executive’s Proportionate Share—12%

Effective Tax Rate—38.25%

The Compensation described above shall be paid in one lump sum payment and (unless provided otherwise herein), it must be paid no later than the fifteenth day of the third calendar month following the date of termination of the Executive’s employment. All of the Employee Benefits payable, other than health coverage, must be paid or reimbursed no later than December 31, of the second year following the year of termination of the Executive’s employment. Nothing in this subsection 7(b)(ii) or elsewhere in this Section 7, shall not be construed or deemed to supersede any Employee Benefits or to reduce or limit Employee Benefits otherwise payable to Executive upon termination, provided that no duplication of any Employee Benefits shall occur as a result hereof.

(c) Resignation . Executive may resign by giving Employer thirty (30) days written notice of his intent to resign. Upon resignation, Executive shall have no claim to any future payments under the terms of this Agreement, excluding accrued Base Compensation, accrued vacation and any awarded but unpaid Management Bonus, allowing for deduction or set-off of any amounts owed to Employer by Executive hereunder, with respect to which Executive has agreed in writing that set-off is permissible. All amounts payable under this Section 7(c) must be paid no later than thirty (30) days following termination of Executive’s employment.

(d) Termination Because of Death or Disability . This Agreement shall be terminated because of Executive’s death or disability. For the purposes of this Section 7(d), Executive is deemed disabled if he is unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or can be expected to last for a continuous period of not less than twelve (12) months. In the event that this Agreement is terminated due to death of Executive, Employer shall pay in one lump sum to Executive’s estate the amount of

5

Base Compensation and accrued vacation due to Executive through the end of the month in which such death occurs within thirty (30) days of death. Payment of any awarded but unpaid Management Bonus to the estate must be made in no event later than (i) end of the calendar year in which Executive’s death occurs or (ii) the fifteenth (15 ^th ) day of the third calendar month following the date of the Executive’s death. In the event that this Agreement is terminated due to disability of Executive, Employer shall pay to Executive the amounts and Employee Benefits described in Section 7(b)(ii) hereof.

(e) Specified Employee . Notwithstanding any provision set forth in this Agreement to the contrary, if the Executive is considered a “specified employee” at the time of his termination of employment that creates a “separation from service,” as that term is defined in Treasury Regulations § 1.409A-1(h), then while the Executive is a specified employee no distributions of compensation shall be made to the Executive during the first six (6) months following his separation from service, unless the Executive dies after his separation from service. During the six (6) month period of time the amounts otherwise payable shall be accumulated and paid to the Executive in a lump sum payment on the first day of the seventh month following the separation from service. The compensation held by the Employer may not be assigned by the Executive or made available to his creditors.
