(B) For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax:

(i) the Executive shall be deemed to pay federal and state income tax at the highest marginal rate of income taxation in the calendar year in which the determination is being made (including applicable social security taxes;

(ii) no portion of the Total Payments shall be taken into account if (a) the Executive waived the receipt or enjoyment of such portion at such time and in such manner as not to constitute a "payment" within the meaning of Section 280G(b) of the Code, (b) in the opinion of tax counsel ("Tax Counsel"), such portion does not constitute a "parachute payment" within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) (such Tax Counsel being reasonably acceptable to the Executive and selected by the Company's independent auditor immediately prior to the Change in Control (the "Auditor")), and/or (c) in the opinion of Tax Counsel, such portion constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the Base Amount allocable to such reasonable compensation. The value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Auditor in accordance with the principles of Sections 280G(d)(3) and (4) of the Code.

(C) At the time that payments are made under this Agreement, the Company shall provide the Executive with a written statement setting forth the manner in which such payments were calculated and the basis for such calculations including, without limitation, any opinions or other advice the Company has received from Tax Counsel, the Auditor or other advisors or consultants (and any such opinions or advice which are in writing shall be attached to the statement).
