Tax Gross-up. If any payment, distribution or provision of a benefit hereunder (a “Payment”) would be subject to an excise tax pursuant to Sections 280G and 4999 of the Internal Revenue Code of 1986, as amended (“Code”), or any interest or penalties with respect to such excise or other additional tax (such excise tax, together with any such interest or penalties, are hereinafter collectively referred to as the “Excise Tax”), the Company, Surviving Corporation or any Subsidiary, as applicable (for purposes of this Section, all such entities are referred to as the “Gross-up Obligor”) shall pay to the Eligible Executive an additional payment (“Gross-up Payment”) in an amount such that, after payment by the Eligible Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including any income taxes and Excise Taxes imposed on any Gross-up Payment, the Eligible Executive retains an amount of the Gross-up Payment equal to the Excise Tax imposed upon the Payments. Notwithstanding the foregoing, however, if the aggregate value of the Payments (as determined in accordance with Code Section 280G) is less than 110% of the product (such product to be referred to herein as the “Excise Tax Threshold”) of three times the Eligible Executive’s “base amount” (as such term is defined in Code Section 280G), then the Eligible Executive shall not be entitled to a Gross-up Payment and the Payments shall be reduced by the Company so that their aggregate value is equal to $1.00 less than the Excise Tax Threshold. If any payment or benefit intended to be provided under this Policy must be reduced in accordance with this Section, the Company shall designate the payments and/or benefits to be so reduced in order to give effect to this Section. The reduction shall first come from payments or benefits that are not permitted to be valued under Q&A 24(c) of Treasury regulation [Section 1.280G]‑1 and then by payments or benefits that are permitted to be valued under Q&A 24(c) of Treasury regulation [Section 1.280G]‑1. The Gross-up Obligor will coordinate with the Eligible Executive to make an initial determination as to whether a Gross-up Payment is required and the amount of any such Gross-up Payment. The Eligible Executive shall notify the Gross-up Obligor in writing of any claim by the Internal Revenue Service which, if successful, would require a Gross-up Payment (or a Gross-up Payment in excess of that initially determined). The Gross-up Obligor shall notify the Eligible Executive in writing at least ten (10) business days prior to the due date of any response required with respect to such claim if it plans to contest the claim. If the Gross-up Obligor decides to contest such claim, the Eligible Executive shall cooperate with the Gross-up Obligor in such action; provided, however, the Gross-up Obligor shall bear and pay all costs and expenses (including additional interest and penalties) incurred in connection with such action and shall indemnify and hold the Eligible Executive harmless, on an after-tax basis, for any Excise Tax or income tax, including interest and penalties with respect thereto, imposed as a result of the Gross-up Obligor’s action. If, as a result of the Gross-up Obligor’s action with respect to any such claim, the Eligible Executive receives a refund of any amount paid by the Gross-up Obligor with respect to such claim, the Eligible Executive shall promptly pay such refund to the Gross-up Obligor. If the Gross-up Obligor fails to timely notify the Eligible Executive whether it will contest such claim or the Gross-up Obligor determines not to contest such claim, then the Gross-up Obligor shall immediately pay to the Eligible Executive the portion of such claim, if any, which it has not previously paid to the Eligible Executive.
