For purposes of this Agreement, "Permanent Disability" shall have the same meaning as is ascribed to such terms in the Disability Policy (including the COBRA Disability Policy) covering Officer at the time of occurrence of such Permanent Disability. (e) REIMBURSEMENT FOR EXPENSES. During the Term of this Agreement, Corporation shall reimburse Officer for all reasonable out-of-pocket business and/or entertainment expenses incurred by Officer for the purpose of and in connection with the performance of his services pursuant to this Agreement.

If any of the Total Payments (as hereinafter defined) will be subject to the tax imposed by Section 4999 of the Code (the "Excise Tax"), Corporation shall pay to Officer, no later than the tenth (10th) day following the Early Termination Date, an additional amount (the "Gross-Up Payment") such that the net amount retained by him, after deduction of any Excise Tax on the Total Payments and any federal and state and local income tax upon the payment provided for by this Paragraph, shall be equal to the excess of the Total Payments over the payment provided for by this Paragraph. For purposes of determining whether any of the Total Payments will be subject to the Excise Tax and the amount of such Excise Tax, (i) all payments or benefits received or to be received by Officer in connection with a Change in Control or the termination of Officer's employment (whether payable pursuant to the terms of this Agreement or of any other plan, arrangement or agreement with 11 Corporation, its successors, any person whose actions result in a Change in Control or any person affiliated (or which, as a result of the completion of the transactions causing a Change in Control, will become affiliated) with Corporation or such person within the meaning of Section 1504 of the Code (the "Total Payments")) shall be treated as "parachute payments" (within the meaning of Section 280G(b)(2) of the Code) unless, in the opinion of tax counsel selected by Corporation's independent auditors and reasonably acceptable to Officer, such payments or benefits (in whole or in part) do not constitute parachute payments, including by reason of Section 280G(b)(4)(A) 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 in the opinion of such tax counsel such excess parachute payments represent reasonable compensation for services actually rendered within the meaning of Section 280G(b)(4)(B) of the Code, or are not otherwise subject to the Excise Tax, and (ii) the value of any noncash benefits or any deferred payment or benefit shall be determined by the Corporation's independent auditors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code.
