If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

“Trustee” means the person named as such in the preamble hereof and, subject to the provisions of Article VI of the Base Indenture, any successor to that person.

Section 2.8 Repurchase upon Change of Control Triggering Event.

(a) If a Change of Control Triggering Event occurs with respect to the Notes, unless the Company shall have exercised its right pursuant to Section 4.1 hereof to redeem the Notes, the Company shall make an offer to each Holder of the Notes to repurchase all or, at such Holder’s option, any part (equal to $2,000 or any integral multiple of $1,000 in excess thereof) of such Holder’s Notes (the “Change of Control Offer”) for payment in cash equal to 101% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the date of purchase (the “Change of Control Payment”).

(b) Within 30 days following any Change of Control Triggering Event with respect to the Notes or, at the Company’s option, prior to any Change of Control but after the public announcement of the transaction or transactions that constitutes or may constitute a Change of Control, the Company shall cause a notice to be mailed to Holders of the Notes, with a copy to the Trustee for the Notes, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required by the Notes and described in such notice. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. Upon 10 Business Days’ advance notice to the Trustee, the Company may request the Trustee to mail the notice to Holders described in this Section 2.8(b) in the name of and at the expense of the Company.

(c) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with this Section 2.8, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under this Section 2.8 by virtue of such conflict.

(e) The Paying Agent shall promptly deliver, to each Holder who properly tendered Notes, the purchase price for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each such Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

(f) The Company shall not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes a Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Tenth Supplemental Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer. In the event that such third party terminates or defaults on its Change of Control Offer, the Company shall be required to make a Change of Control Offer treating the date of such termination or default as though it were the date of the Change of Control Triggering Event.

(g) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making such an offer in lieu of the Company, purchases all of such Notes properly tendered and not withdrawn by such Holders, the Company or such third party will have the right, upon not less than 10 days’ nor more than 60 days’ prior notice, provided that such notice is given not more than 30 days following such repurchase pursuant to the Change of Control Offer, to redeem all Notes that remain outstanding following such purchase on a date specified in such notice (the “Second Change of Control Payment Date”) and at a price in cash equal to 101% of the aggregate principal amount of the Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to, but excluding, the Second Change of Control Payment Date.

The foregoing restriction, however, shall not require the Company to secure the Notes if the Lien consists of either of the following:

(a) Permitted Liens; or

(b) Liens securing Indebtedness if at the time of determination, after giving pro forma effect to the incurrence, creation, assumption or guaranty of such Indebtedness or the securing of outstanding Indebtedness and to the retirement of Indebtedness which is concurrently being retired, the sum of (without duplication) (i) the aggregate principal amount of all Indebtedness of the Company and its Subsidiaries secured by Liens (other than Permitted Liens) and (ii) all Attributable Debt in respect of Sale and Lease-Back Transactions not otherwise permitted under the first sentence of Section 3.2 hereof, does not exceed fifteen percent of Consolidated Net Tangible Assets.

(a) the Company or such Significant Subsidiary, as applicable, could have incurred Indebtedness secured by a Lien on the Principal Property involved in such Sale and Lease-Back Transaction in an amount at least equal to the Attributable Debt with respect to such Sale and Lease-Back Transaction, without equally and ratably securing the Notes, pursuant to Section 3.1 hereof; or

(b) the proceeds of such Sale and Lease-Back Transaction are at least equal to the fair market value of the affected Principal Property (as determined in good faith by the Company’s Board of Directors) and the Company applies an amount equal to the net proceeds of such Sale and Lease-Back Transaction within 365 days of such Sale and Lease-Back Transaction to any (or a combination) of:

(i) the prepayment or retirement of the Notes,

(ii) the prepayment or retirement (other than any mandatory retirement, mandatory prepayment or sinking fund payment or by payment at maturity) of other Indebtedness of the Company or of one of its Subsidiaries (other than Indebtedness that is subordinated to the Notes or Indebtedness owed to the Company or one of its Subsidiaries) that matures more than 12 months after its creation; or

(iii) the purchase, construction, development, expansion or improvement of other comparable property.

Notwithstanding the foregoing, the Company and its Significant Subsidiaries shall be allowed to enter into any Sale and Lease-Back Transaction if, after giving pro forma effect to such Sale and Lease-Back Transaction, the sum of (without duplication) (i) the aggregate principal amount of all Indebtedness of the Company and its Subsidiaries secured by Liens (other than Permitted Liens) and (ii) all Attributable Debt in respect of Sale and Lease-Back Transactions not otherwise permitted under the first sentence of this Section 3.2, does not exceed fifteen percent of Consolidated Net Tangible Assets.

ARTICLE 4.

(i) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the date of redemption; and

(ii) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

Subject to Article XI of the Base Indenture, on or after the Par Call Date, the Company shall have the right to redeem the Notes, in whole or in part, at any time or from time to time, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

The applicable redemption price in connection with a redemption of Notes under either of the first two paragraphs of this Section 4.1(a) is referred to herein as the “Optional Redemption Price” with respect to such redemption.

On and after a Redemption Date, interest will cease to accrue on the Notes called for redemption (unless the Company defaults in the payment of the Optional Redemption Price and accrued interest). On or before a Redemption Date, the Company will deposit with a Paying Agent (or the Trustee) money sufficient to pay the Optional Redemption Price of and accrued interest on the Notes to be redeemed on that date.

(b) Notice of any redemption pursuant to this Section 4.1 shall be given as provided in Section 1104 of the Base Indenture, except that (i) any notice of such redemption shall not specify the related Optional Redemption Price but only the manner of calculation thereof and (ii) notice shall be given not less than 10 days prior to the Redemption Date.
