(“Gross-Up Eligible Payments”) would be subject to the excise tax imposed by Section 4999 of the Code (or any othersimilar tax that may hereafter be imposed) on such benefits (the “Excise Tax”), the Corporation shall pay to the Participant anadditional payment (the “Excise Tax Gross-Up Payment”) to compensate such Participant for any Excise Tax due and owing by the Participant with respect to the Gross-Up Eligible Payments. The Excise Tax Gross-Up Payment shall equal (i) the amount of such Excise Taxes on Gross-Up Eligible Payments plus (ii) a payment to compensate such Participant for the federal (and to the degree applicable, state and local) income taxes, federal Medicare taxes and additional Excise Taxes attributable to the amount of such additional payment, calculated in accordance with Section 4.11.

For all purposes of this Section 4.10, 4.11, and 4.13, the calculations and determinations made shall be made periodically prior to a Change in Control and only by the Committee as constituted from time to time prior to a Change in Control. On and after a Change in Control, the Committee shall have no power or authority to modify the calculations previously made prior to the Change in Control.

2.   Section 4.11 is amended to read as follows:

4.11Tax Computation. For purposes of determining whether a payment or distribution is a Gross-Up Eligible Payment and the amount of the Excise Tax and the Excise Tax Gross-Up Payment referred to in Section 4.10, the Committee shall act reasonably and apply awhether any of a Participant’s SEBP Benefit or Performance Share Benefit (as defined in Section 4.10) will be subject to the Excise Tax, and the amounts of such Excise Tax: (i) there shall be taken into account all other payments or benefits received or to be received by a Participant in connection with a Change in Control of the Corporation (whether pursuant to the terms of this Plan or any other plan, arrangement, or agreement with the Corporation, any person whose actions result in a Change in Control of the Corporation or any person affiliated with the Corporation or such person); and (ii) the amount of any Gross-Up Payment payable with respect to any Participant (or his Beneficiary) by reason of such payment shall be determined in accordance with a customary “gross-up formula,” as determined by the Committee in its sole discretion.

4.13No Subsequent Recalculation of Plan Liability. The Excise Tax Gross-Up Payments described in Sections 4.10 and 4.11 are intended and hereby deemed to be a reasonably accurate calculation of each Participant’s actual income tax and Excise Tax liability under the circumstances (or such tax liability of his Beneficiary), the payment of which is to be made by the Corporation or any “rabbi trust” established by the Corporation for such purposes. All such calculations of tax liability shall not be subject to subsequent recalculation or adjustment in either an underpayment or overpayment context with respect to the actual tax liability of the Participant (or his Beneficiary) ultimately determined as owed.

IN WITNESS WHEREOF, the Company has caused this SCANA Corporation Supplementary Executive Benefit Plan to be amended by its duly authorized officer to be effective as of November 1, 2006.
