“Make Whole Amount” means, as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the date of redemption) discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points.

Incorporated, and its respective successor and three other nationally recognized investment banking firms that are Primary Treasury Dealers specified from time to time by the Company; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), we shall substitute therefor another Primary Treasury Dealer; and (ii) any other Primary Treasury Dealer selected by the Company.

“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having a maturity comparable to the remaining term of the securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such securities.

“Comparable Treasury Price” means, with respect to any redemption date, (i) the average of the Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (ii) if the Trustee obtains fewer than three such Reference Treasury Dealer Quotations, the average of all such Quotations.

Notice of redemption shall not be given not less than 30 not more than 60 days prior to the redemption date to each Holder of Securities to be redeemed.  Pursuant to the provisions of the Indenture, the Company shall give to the Trustee notice of its election to redeem such Securities, in whole or in part, on the redemption date, stating the principal amount in increments of $1,000 of the Securities to be redeemed, provided that any remaining principal amount of each of this Security and any other Securities shall be at least $100,000.  In the case of partial redemption, such notice shall state the principal amount of any such Securities to be redeemed.  If less than all the Securities are to be redeemed, the particular Securities to be redeemed shall be selected by the Trustee from the Outstanding Securities not previously called for redemption by lot or by such other method as the Trustee and the Company

shall approve.  The Trustee shall promptly give to the Company notice of the Securities selected for redemption.  Upon any partial redemption of any Security of this series, the Company will issue and the Trustee shall authenticate and make available for delivery in exchange therefor one or more Securities of the same series, of any authorized denomination and like tenor, as requested by the Holder, in aggregate principal amount equal to the unredeemed portion of the principal of such Security.

Each Holder of the Securities, by the acceptance thereof, agrees to and shall be bound by such provisions of the Indenture.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be immediately declared due and payable in the manner and with the effect provided in the Indenture.

As provided in the Indenture, the Company shall be discharged from its obligations with respect to the Securities of any series when (1) with respect to all Outstanding Securities of such series, the Company has irrevocably deposited or caused to be deposited with the Trustee as a trust fund specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Securities of such series (i) money in an amount as will, or (ii) U.S. Government Obligations as will, together with the predetermined and certain income to accrue thereon without consideration of any reinvestment thereof, or (iii) a combination of (i) and (ii) as will (in a written opinion with respect to (ii) or (iii) of independent public accountants delivered to the Trustee), be sufficient to pay and discharge the entire indebtedness on all Outstanding Securities of such series for principal (and premium, if any) and interest, if any, to the Stated Maturity; and (2) the Company has paid or caused to be paid all other sums payable with respect to the Outstanding Securities of such series; and (3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel stating that all such conditions precedent have been complied with; and (4) the Company has delivered to the Trustee (i) a ruling directed to the Company and the Trustee from the United States Internal Revenue Service to the effect that Holders of the Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result thereof and will be subject to Federal income tax as if such option had not been exercised or (ii) an opinion of Counsel to the same effect and based upon a change in law.

No reference herein to the Indenture and no provisions of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest, if any, on this Security at the times, place and rate, and in the coin or currency, herein and in the Indenture provided; subject, however, to the provisions for the discharge of the Company from its obligations under the Securities upon satisfaction of the conditions set forth in the preceding paragraph or in the Indenture.

As provided in the Indenture, upon any consolidation or merger or any conveyance, transfer or lease of the properties and assets of the Company substantially as an entirety in accordance with the provisions of the Indenture, the successor corporation formed by such consolidation or into which the predecessor corporation is merged or to which such conveyance, transfer or lease is made shall be substituted for the predecessor corporation with the same effect as if such successor corporation had been named as the Company.  Thereafter the predecessor corporation shall be relieved of the performance and observance of all obligations and covenants of the Indenture and the Securities, including but not limited to the obligation to make payment of the principal of (and premium, if any, on) and interest, if any, on all the Securities then Outstanding, and, in the event of any such conveyance, transfer or lease, may be liquidated and dissolved.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
