(g) Benefits paid to an Employee from the Excess Benefit Plan shall include an amount equivalent to the additional benefit the Employee would have received under The Retirement Plan if, for purposes of that Plan, the definition of compensation included amounts for any payments made pursuant to Section 4 of this Policy and if, for purposes of the Retirement Plan, there was no limitation on the amount of compensation that could be taken into account. 5. Excise Tax Gross-up. In the event that an Employee becomes entitled to one or more payments (with a "payment" including, without limitation, the vesting of an option or other non-cash benefit or property, whether pursuant to the terms of this Agreement or any other Plan (the "Total Payments"), which are or become subject to the tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), (or any similar tax that may hereafter be imposed) (the "Excise Tax"), the Company shall pay to the Employee at the time specified below an additional amount (the "Gross-up Payment") (which shall include, without limitation, reimbursement for any penalties and interest that may accrue in respect of such Excise Tax) such that the net amount retained by the Employee, after reduction for any Excise Tax (including any penalties or interest thereon) on the Total Payments and any federal, state and local income or employment tax and Excise Tax on the Gross-up Payment provided for by this Section 5, but before reduction for any federal, state or local income or employment tax on the Total Payments, shall be equal to the product of any deductions disallowed for federal, state or local income tax purposes because of the inclusion of the Gross-up Payment in Employee's adjusted gross income multiplied by the highest applicable marginal rate of federal, state or local income taxation, respectively, for the calendar year in which the Gross-up Payment is to be made. For purposes of determining whether any of the Total Payments will be subject to the Excise Tax and the amount of such Excise Tax, -8- (i) the Total Payments shall be treated as "parachute payments" within the meaning of Section 280G(b)(2) of the Code, and all "excess parachute payments" within the meaning of Section 280G(b)(1) of the Code shall be treated as subject to the Excise Tax, unless, and except to the extent that, in the written opinion of independent compensation consultants or auditors of nationally recognized standing selected by the Company and reasonably acceptable to the Employee ("Independent Auditors"), the Total Payments (in whole or in part) do not constitute parachute payments, or such excess parachute payments (in whole or in part) represent reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4) of the code in excess of the base amount within the meaning of Section 280G(b)(3) of the Code or are otherwise not subject to the Excise Tax, (ii) the amount of the Total Payments which shall be treated as subject to the Excise Tax shall be equal to the lesser of (A) the total amount of the Total Payments or (B) the amount of excess parachute payments within the meaning of Section 280G(b)(1) of the Code (after applying clause (i) above), and (iii) the value of any non-cash benefits or any deferred payment or benefit shall be determined by the Company's Independent Auditors appointed pursuant to clause (a) above in accordance with the principles of Sections 280G(d)(3) and (4) of the Code. For purposes of determining the amount of the Gross-up Payment, the Employee shall be deemed (A) to pay federal income taxes at the highest marginal rate of federal income taxation for the calendar year in which the Gross-up Payment is to be made; (B) to pay any applicable state and local income taxes at the highest marginal rate of taxation for the calendar in which the Gross-up Payment is to be made, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes if paid in such year (determined without regard to limitations on deductions based upon the amount of the Employee's adjusted gross income); and (C) to have otherwise allowable deductions for federal, state and local income tax purposes at least equal to those disallowed because of the inclusion of the Gross-up Payment in the Employee's adjusted gross income. In the event that the Excise Tax is subsequently determined to be less than the amount taken into account hereunder at the time the Gross-up Payment is made, the Employee shall repay to the Company at the time that the amount of such reduction in Excise Tax is finally determined (but, if previously paid to the taxing authorities, not prior to the time the amount of such reduction is refunded to the Employee or otherwise realized as a benefit by the Employee) the portion of the Gross-up Payment that would not have been paid if such Excise Tax had been applied in initially calculating the Gross-up Payment, plus interest on the amount of such repayment at the rate provided in Section 1274(b)(2)(B) of the Code. In the event that the Excise -9- Tax is determined to exceed the amount taken into account hereunder at the time the Gross-up Payment is made (including by reason of any payment the existence or amount of which cannot be determined at the time of the Gross-up Payment), the Company shall make an additional Gross-up Payment in respect of such excess (plus any interest and penalties payable with respect to such excess) at the time that the amount of such excess is finally determined. The Gross-up Payment provided for above shall be paid on the thirtieth day (or such earlier date as the Excise Tax becomes due and payable to the taxing authorities) after it has been determined that the Total Payments (or any portion thereof) are subject to the Excise Tax; provided, however, that if the amount of such Gross-up Payment or portion thereof cannot be finally determined on or before such day, the Company shall pay to the Employee on such day an estimate, as determined by the Company's Independent Auditors appointed pursuant to clause (i) above, of the minimum amount of such payments and shall pay the remainder of such payments (together with interest at the rate provided in Section 127(b)(2)(B) of the Code), as soon as the amount thereof can be determined. In the event that the amount of the estimated payments exceeds the amount subsequently determined to have been due, such excess shall constitute a loan by the Company to the Employee, payable on the fifth day after demand by the Company (together with interest at the rate provided in Section 1274(b)(2)(B) of the code). If more than one Gross-up Payment is made, the amount of each Gross-up Payment shall be computed as not to duplicate any prior Gross-up Payment. The Company shall have the right to control all proceedings with the Internal Revenue Service that may arise in connection with the determination and assessment of the Excise Tax and, at its sole option, the Company may pursue or forego any and all administrative appeals, proceedings, hearings and conferences with any taxing authority in respect of such Excise Tax (including any interest or penalties thereon); provided, however, that the Company's control over any such proceedings shall be limited to issues with respect to which a Gross-up Payment would be payable hereunder and the Employee shall be entitled to settle or contest any other issue raised by the Internal Revenue Service or any other taxing authority. The Employee shall cooperate with the Company in any proceedings relating to the determination and assessment of the Excise Tax and shall not take any position or action that would materially increase the amount of any Gross-up Payment hereunder. 6. Withholding. The Company shall have the right to deduct from all payments hereunder any taxes required by law to be withheld therefrom. 7. No Right To Employment. Nothing in this Policy shall be construed as giving any person the right to be retained in the employment of the Company or any subsidiary, nor shall it affect the right of the Company or any subsidiary to dismiss an Employee without any liability except as provided in this Policy. -10- 8. Legal Fees. The Company shall pay all legal fees and related expenses incurred by an Employee in seeking to obtain or enforce any payment, benefit or right provided by this Policy; provided; however, that the Employee shall be required to repay any such amounts to the Company to the extent that an arbitrator or a court of competent jurisdiction issues a final, unappealable order setting forth a determination that the position taken by the Employee was frivolous or advanced in bad faith. 9. Amendment and Termination. The Board of Directors of the Company may amend or terminate this Policy at any time prior to a Change in Control. This Policy may not be amended or terminated at any time after a Change in Control in any manner adverse to an Employee without the prior consent of such Employee. 10. Governing Law; Arbitration. The validity, construction, and effect of this Policy and any rules and regulations relating to this Policy shall be determined in accordance with Delaware General Corporation Law, to the extent applicable, other laws (including those governing contracts) of the State of Delaware, without giving effect to principles of conflicts of laws, and applicable federal law. If any provision hereof shall be held by a court of competent jurisdiction to be invalid and unenforceable, the remaining provisions hall continue to be fully effective. Any dispute or controversy arising under or in connection with this Policy shall be settled exclusively by arbitration in Atlanta, Georgia by three arbitrators in accordance with the rules of the American Arbitration Association in effect at the time of submission to arbitration. Judgment may be entered on the arbitrators' award in any court having jurisdiction. For purposes of settling any dispute or controversy arising hereunder or for the purpose of entering any judgment upon an award rendered by the arbitrators, the Company and the Employee hereby consent to the jurisdiction of any or all of the following courts: (i) the United States District Court for the Northern District of Georgia, (ii) any of the courts of the State of Georgia, or (iii) any other court having jurisdiction. The Company and the Employee hereby waive, to the fullest extent permitted by applicable law, any objection which it may now or hereafter have to such jurisdiction and any defense of inconvenient forum. The Company and the Employee hereby agree that a judgment upon an award rendered by the arbitrators may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. 11. Nonassignability. Compensation and benefits under the Policy may not be assigned by the Employee. The terms and conditions of this Policy shall be binding on the successors and assigns of the Company. 12. No Duty to Mitigate. No employee shall be required to mitigate, by seeking employment or otherwise, the amount of any payment that the Company becomes obligated to make under this Policy, and, except as expressly provided in this Policy, amounts or other benefits to be paid or provided to an Employee pursuant to this -11- Policy shall not be reduced by reason of the Employee's obtaining other employment or receiving similar payments or benefits from another employer. 13. Duplicate Payments or Benefits. (a) Except to the extent that the terms of this Policy confer compensa- tion or benefits that are more favorable to Employee than are available under any other employee (including executive) benefit of executive compensation plan of the company in which Employee is a participant, Employee's rights under any such employee (including executive) benefit plan or executive compensation plan shall be determined in accordance with the terms of such plan (as it may be modified or added to by the Company from time to time). (b) This Policy constitutes the entire understanding between the Company and Employee relating to employment of Employee by the Company and its subsidiaries and supersedes and cancels all prior agreements and understandings with respect to the subject matter of this Policy. Employee shall not be entitled to any payment or benefit under this Policy which duplicates a payment or benefit received or receivable by Employee under such prior agreements and understandings or under any employee (including executive) benefit plan or executive compensation plan of the Company. 14. Effective Date. This Policy is effective as of November 15, 1993. -12-
