(B) 100% of the principal amount of the 2030 Notes to be redeemed,

(b) The 2035 Notes

(i) Prior to October 15, 2034 (three months prior to the maturity date of the 2035 Notes) (the “2035 Notes Par Call Date” and, together with the 2030 Notes Par Call Date, the “Par Call Dates”), the Issuer may redeem the 2035 Notes at its option, in whole or in part, at any time or from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

-13-

(B) 100% of the principal amount of the 2035 Notes to be redeemed,

(c) The following terms have the meanings given to them in this Section 3.01(c):

“Treasury Rate” means, with respect to any redemption date for any series of Notes, the yield determined by the Issuer in accordance with the following two paragraphs:

(i) The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities—Treasury constant maturities—Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the applicable Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

(ii) If on the third Business Day preceding the redemption date H.15 TCM is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the applicable Par Call Date, as applicable. If there is no United States Treasury security maturing on such Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from such Par Call Date, one with a maturity date preceding such Par Call Date and one with a maturity date following such Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding such Par Call Date. If there are two or more United States Treasury securities maturing on such Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer 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

-14-

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.

(iii) The Issuer’s actions and determinations in determining the redemption price for the Notes of any series shall be conclusive and binding for all purposes, absent manifest error.

Section 3.02. Offer to Purchase.

(a) An “Offer to Purchase” means an offer by the Company to purchase Notes as required by Section 4.05. An Offer to Purchase must be made by written offer (the “offer”) sent to the Holders. The Company will notify the Trustee at least 15 days (or such shorter period as is acceptable to the Trustee) prior to sending the offer to Holders of its obligation to make an Offer to Purchase, and the offer will be sent by the Company or, at the Company’s request, by the Trustee in the name and at the expense of the Company. Such request shall be evidenced by an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 3.02(b).

(b) The offer must include or state the following as to the terms of the Offer to Purchase:

(1) the Offer to Purchase is being made pursuant to Section 4.05;

(2) that the Company is offering to purchase all outstanding Notes (the “purchase amount”);

(3) the purchase price, including the portion thereof representing accrued interest;

(4) an expiration date (the “expiration date”) not less than 15 days or more than 60 days after the date of the offer, and a settlement date for purchase (the “purchase date”) not more than five Business Days after the expiration date;

(5) a description of the transaction or transactions that constituted the requirement to make the Offer to Purchase;

(6) a Holder may tender all or any portion of its Notes, subject to the requirement that any portion of a Note tendered must be equal to $2,000 principal amount or a higher multiple of $1,000 principal amount (provided, that any unpurchased portion of the Note must be in a minimum principal amount of $2,000);

(7) the place or places where Notes are to be surrendered for tender pursuant to the Offer to Purchase;

(8) each Holder electing to tender a Note pursuant to the offer will be required to surrender such Note at the place or places specified in the offer prior to the close of business on the expiration date (such Note being, if the Company or the Trustee so requires, duly endorsed or accompanied by a duly executed written instrument of transfer);

(9) interest on any Note not tendered, or tendered but not purchased by the Company pursuant to the Offer to Purchase, will continue to accrue;

-15-

(10) on the purchase date the purchase price will become due and payable on each Note accepted for purchase, and interest on Notes purchased will cease to accrue on and after the purchase date;

(11) Holders are entitled to withdraw Notes tendered by giving notice, which must be received by the Company or the Trustee not later than the close of business on the expiration date, setting forth the name of the Holder, the principal amount of the tendered Notes, the certificate number of the tendered Notes and a statement that the Holder is withdrawing all or a portion of the tender;

(12) the Company will purchase all Notes duly tendered and not withdrawn pursuant to the Offer to Purchase;

(13) if any Note is purchased in part, new Notes equal in principal amount to the unpurchased portion of the Note will be issued; and

(14) if any Note contains a CUSIP number, no representation is being made as to the correctness of the CUSIP number either as printed on the Notes or as contained in the offer and that the Holder should rely only on the other identification numbers printed on the Notes.

(c) Prior to the purchase date, the Company will accept tendered Notes for purchase as required by the Offer to Purchase and deliver to the Trustee all Notes so accepted together with an Officer’s Certificate specifying which Notes have been accepted for purchase. On the purchase date, the purchase price will become due and payable on each Note accepted for purchase, and interest on Notes purchased will cease to accrue on and after the purchase date; provided, that the Company has not defaulted in depositing the purchase price in accordance with the provisions hereof. The Trustee will promptly return to Holders any Notes not accepted for purchase and send to Holders new Notes equal in principal amount to any unpurchased portion of any Notes accepted for purchase in part.

(d) The Company will comply with Rule 14e-1 under the Exchange Act and all other applicable laws in making any Offer to Purchase, and the above procedures will be deemed modified as necessary to permit such compliance, and the Company shall not be deemed to have breached its obligations under the Indenture or the Notes as a result of such compliance.

(e) In the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes of any series accept an Offer to Purchase following a Change of Control Triggering Event and the Company purchases all of the Notes of such series held by such Holders, the Company will have the right, upon not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Offer to Purchase described above, to redeem all of the Notes of such series that remain outstanding following such purchase at a redemption price equal to 101% of the aggregate principal amount of Notes redeemed, plus accrued and unpaid interest, if any, thereon to, but excluding, the date of redemption, subject to the right of the Holders of record on the relevant Regular Record Date to receive interest due on an Interest Payment Date that is on or prior to such date of redemption.

Section 4.02. Limitation on Liens.

(a) The Company will not, and will not permit any Restricted Subsidiary to, directly or indirectly, incur or permit to exist any Liens of any nature whatsoever that secure Debt on any Principal Property of the Company or any Restricted Subsidiary, or on shares of Capital Stock or Debt issued by any Restricted Subsidiary and owned by the Company or any Restricted Subsidiary, whether the Principal Property, shares of Capital Stock or Debt were owned at the Issue Date or thereafter acquired, other than Permitted Liens, without effectively providing, substantially concurrently with or prior to the creation of such Lien, that the Notes (or, in the case of a Restricted Subsidiary that is a Guarantor, its Note Guarantee) are secured equally and ratably with (or, if the obligation to be secured by the Lien is subordinated in right of payment to the Notes or any Note Guarantee, prior to) the obligations so secured for so long as such obligations are so secured.

(b) For purposes of determining compliance with this Section 4.02, (A) a Lien securing an item of Debt need not be permitted solely by reference to one category (or portion thereof) described in the definition of “Permitted Liens,” but may be permitted in part under any combination thereof and (B) in the event that a Lien securing an item of Debt (or any portion thereof) meets the criteria of one or more of the categories (or portions thereof) of Permitted Liens, the Company shall, in its sole discretion, divide, classify or reclassify, or later divide, classify, or reclassify, such Lien securing such item of Debt (or any portion thereof) in any manner that complies (based on circumstances existing at the time of such division, classification or reclassification) with this Section 4.02.

Section 4.04. Guarantees by Domestic Subsidiaries. Each Domestic Subsidiary that Guarantees any Debt under the Credit Agreement on the Issue Date shall guarantee the Notes in accordance with the terms of Article 13 of the Base Indenture.

ARTICLE 5

DEFAULT AND REMEDIES

Section 5.01. Events of Default. In addition to the Events of Default set forth in Section 5.01 of the Base Indenture, each of the following is an “Event of Default” with respect to Notes of a series:

(1) (i) any failure to pay indebtedness for money the Company borrowed or guaranteed the payment of in an aggregate principal amount of at least $100 million at the later of Stated Maturity and the expiration of any related applicable grace period and such defaulted payment shall not have been made, waived or extended within 30 days or (ii) acceleration of the Stated Maturity of any indebtedness for money that the Company borrowed or guaranteed the payment of in an aggregate principal amount of at least $100 million, if such indebtedness has not been discharged in full or such acceleration has not been rescinded or annulled within 30 days; provided, however, that, if the default under the instrument is cured by the Company, or waived by the holders of the indebtedness, in each case as permitted by the governing instrument, then the Event of Default under the Indenture caused by such default will be deemed likewise to be cured or waived; or

(2) any Note Guarantee of a Significant Subsidiary (or a group of Subsidiaries that would, taken together, be a Significant Subsidiary) ceases to be in full force and effect, other than in accordance the terms of the Indenture, or a Guarantor that is a Significant Subsidiary (or a group of Subsidiaries that would, taken together, be a Significant Subsidiary) denies or disaffirms its obligations under its Note Guarantee.

However, if an Event of Default under clauses (1) or (2) occurs and is continuing under the Indenture with respect to Notes of a series, the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes of such series then outstanding, by written notice to the Company (and to the Trustee if the notice is given by the Holders), may, and the Trustee at the request of such Holders shall, declare the principal of and accrued and unpaid interest on the Notes of such series to be immediately due and payable. Upon a declaration of acceleration, such principal and interest will become immediately due and payable.

In the event of a declaration of acceleration of the Notes solely because an Event of Default described in clause (1) above has occurred and is continuing, the declaration of acceleration of the Notes shall be automatically rescinded and annulled if the event of default or payment default triggering such Event of Default pursuant to clause (1) shall be remedied or cured by the Company or a Significant Subsidiary of the Company or waived (and the related declaration of acceleration rescinded or annulled) by the holders of the relevant Debt within 20 Business Days after the declaration of acceleration with respect to the Notes and if the rescission and annulment of the acceleration of the Notes would not conflict with any judgment or decree of a court of competent jurisdiction obtained by the Trustee for the payment of amounts due on the Notes.
