(b) Except as otherwise expressly provided in this Agreement, the Executive's entitlement to benefits under the employee benefit plans and benefit arrangements maintained by Clark USA and the Corporation, shall be determined under the terms of the respective plans as in effect from time to time, with such entitlement based on the fact that the Executive's employment with Clark USA and the Corporation ceased on the Executive's Date of Termination.

(b) Subject to the provisions of subsection VI.5(c), all determinations required to be made under this subsection VI.5, including whether and when a Gross-Up Payment is required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by such nationally recognized certified public accounting firm as may be designated by the Executive (the "Accounting Firm") which shall provide detailed supporting calculations both to the Corporation and the Executive within fifteen (15) business days of the receipt of notice from the Executive that there has been a Payment, or such earlier time as is requested by the Corporation. All fees and expenses of the Accounting Firm shall be borne solely by the Corporation. Any Gross-Up Payment, as determined pursuant to this Ection VI.5, shall be paid by the Corporation to the Executive within five (5) days after the receipt of the Accounting Firm's determination. If the Accounting Firm determines that no Excise Tax is payable by the Executive, it shall so indicate to the Executive in writing. Any dtermineation by the Accounting Firm shall be binding upon the Corporation and the Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Corporation should have been made ("Underpayment"), consistent with the calculations required to be made hereunder. In the event that the Corporation exhausts its remedies pursuant to subsection VI.5(c) and the Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Corporation to or for the benefit of the Executive. (c) The Executive shall notify the Corporation in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Corporation of the Gross-Up Payment. Such notification shall be given as soon as practicable but no later than ten (10) business days after the 18 Executive is informed in writing of such claim and shall apprise the Corporation 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 thirty (30) day period following the date on which it gives such notice to the Corporation (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Corporation notifies the Executive in writing prior to the expiration of such period that it desires to contest such claim, the Executive shall: (1) give the Corporation any information requested by the Corporation relating to such claim; (2) take such action in connection with contesting such claim as the Corporation 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 Corporation; (3) cooperate with the Corporation in good faith in order to effectively contest such claim; and (4) permit the Corporation to participate in any proceedings relating to such claim; provided, however, that the Corporation shall bear and pay directly all costs - -------- ------- and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold the Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto, other than interest or penalties imposed as a result of the failure of the Executive to file any tax return or pay any tax (except any such failure to pay tax in accordance with the terms hereof), required by applicable law to be filed or paid by the Executive) imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this subsection 5.5(c), the Corporation shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forego 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 Corporation shall determine; provided, however, that if the Corporation directs the Executive to -------- ------- pay such claim and sue for a refund, the Corporation shall advance the amount of 19 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 Excise Tax or income tax (including interest or penalties with respect thereto, other than interest or penalties imposed as a result of the failure of the Executive to file any tax return or pay any tax (except any such failure to pay tax in accordance with the terms hereof), required by applicable law to be filed or paid by the Executive) 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 statute of limitations to enable the Corporation to contest such claim, the Executive may limit this extension solely to such contested amount. The Corporation's control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder 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. (d) If, after the receipt by the Executive of an amount advanced by the Corporation pursuant to subsection VI.5(c), the Executive becomes entitled to receive any refund with respect to such claim, the Executive shall (subject to the Corporation's complying with the requirements of subsection VI.5(c)) promptly pay to the Corporation the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by the Executive of an amount advanced by the Corporation pursuant to subsection VI.5(c), a determination is made that the Executive shall not be entitled to any refund with respect to such claim and the Corporation does not notify the Executive in writing of its intent to contest such denial of refund prior to the expiration of thirty (30) days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid.
