 WITNESSETH: 
 WHEREAS, the Company, the Guarantor and the Trustee entered into an Indenture, dated as of December 21, 2007 (the “Original Indenture”), pursuant to which one or more series of debt

 For and in consideration of the premises and the purchase of the Notes to be issued hereunder by holders thereof, the Company, the Guarantor

 ARTICLE ONE 
 Definitions and Other Provisions of General Application

 Section 101. Definitions 
 All capitalized terms that are used herein and not otherwise defined herein shall have the meanings assigned to them in the Original Indenture. The Original Indenture together with this Third Supplemental
Indenture are hereinafter sometimes collectively referred to as the “Indenture.” As used in this Third Supplemental Indenture, the following capitalized terms shall have the following respective meanings: 
 “Business Day” means any day other than a Saturday or Sunday that is neither a legal holiday nor a day on which banking
institutions are authorized or required by law or regulations to close in the City of New York. 
 “Comparable Treasury
Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed that would be used, 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 Notes; provided, however, that if the remaining term of such Notes to be redeemed is less than one
year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used. 
 “Comparable Treasury Price” means (1) the average of five Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury
Dealer Quotations, or (2) if an Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Depositary” means The Depository Trust Company or its successor. 
 “Independent Investment Banker” means any of Citigroup Global Markets Inc., J.P. Morgan Securities Inc., or Morgan Stanley & Co. Incorporated or any of their respective successors, as designated by the Company, or
if all of those firms are unwilling or unable to serve as such, an independent investment and banking institution of national standing appointed by the Company. 
 “Interest Payment Date” means March 15 and September 15 of each year. 
 “Original Issue Date” means the date upon which the Notes are initially issued by the Company, such date to be set forth on the face of each Note. 
 “Record Date” means the fifteenth calendar day (whether or not a Business Day) immediately preceding the related Interest
Payment Date. The Record Date shall constitute the Regular Record Date for purposes of the Original Indenture. 
  

 2 

 “Reference Treasury Dealer” means: 
 (i) Citigroup Global Markets Inc., J.P. Morgan Securities Inc. or Morgan Stanley & Co. Incorporated, and each of
their respective successors; provided that, if any such Reference Treasury Dealer ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute another
Primary Treasury Dealer; and 
 (ii) up to two other Primary Treasury Dealers selected by the Company.

 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any
redemption date, the average, as determined by an Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to an Independent
Investment Banker at 3:30 p.m., New York City time, on the third Business Day preceding such redemption date. 
 “Treasury Rate” means, as of any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity (computed as of the second Business Day immediately preceding that redemption date) 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 that redemption date. 
 Section 102. Section References 
 Each reference to a particular section set forth in this Third Supplemental Indenture shall, unless the context otherwise requires, refer to this Third Supplemental Indenture. 
 ARTICLE TWO

Section 202. Variations in Terms of the 2016 Notes 
 Subject to the terms and conditions set forth in the Original Indenture and in this Third Supplemental Indenture, the terms of any particular

any Interest Payment Date would otherwise be a day that is not a Business Day, the payment required to be made on such Interest Payment Date will be postponed to the next succeeding Business Day, and no interest will accrue on such payment for the
period from and after such Interest Payment Date to the date of such payment on the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding
Business Day, in each case with the same force and effect as if made on such Interest Payment Date.

 The following terms, as used herein, have the following meanings unless the context or use clearly indicates another or different meaning or intent: 
 “Business Day” shall mean any day other than a Saturday or Sunday that is neither a legal holiday nor a day on which banking institutions are authorized or obligated by law or regulations
to close in the City of New York. 
 “Comparable Treasury Issue” means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Notes to be redeemed that would be used, 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 the Notes; provided, however, that if the remaining term of the Notes to be redeemed is less than one year, the weekly average yield on actually traded United States
Treasury securities adjusted to a constant maturity of one year will be used. 
 “Comparable Treasury Price”
means (1) the average of five Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if an Independent Investment Banker obtains fewer than five
such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Depositary” shall mean The
Depository Trust Company or any successor depositary. 
 “Independent Investment Banker” means any of Citigroup
Global Markets Inc., J.P. Morgan Securities Inc., or Morgan Stanley & Co. Incorporated or any of their respective successors, as designated by the Company, or if all of those firms are unwilling or unable to serve as such, an independent
investment and banking institution of national standing appointed by the Company. 

 “Interest Payment Date” shall mean the date on which interest on this Note
is paid, which date(s) are set forth on the face of this Note. 
 “Reference Treasury Dealer” means:

 (i) Citigroup Global Markets Inc., J.P. Morgan Securities Inc. or Morgan Stanley & Co. Incorporated, and each of
their respective successors; provided that, if any such Reference Treasury Dealer ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), the Company will substitute another Primary
Treasury Dealer; and 
 (ii) up to two other Primary Treasury Dealers selected by the Company. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the
average, as determined by an Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to an Independent Investment Banker at 3:30
p.m., New York City time, on the third Business Day preceding such redemption date. 
 “Treasury Rate” means,
as of any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity (computed as of the second Business Day immediately preceding that redemption date) 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 that redemption date. 
 INTEREST RATE 
 This Note will bear interest at the rate per annum
(computed based on a 360-day year consisting of twelve 30-day months) identified on the face of this Note. Except for the effect of any adjustment in the Interest Payment Date as provided in the following sentence, the amount of interest payable for
any period shorter than a full six-month period for which interest is computed, will be computed on the basis of the actual number of days elapsed in such a 180-day period. If any Interest Payment Date would otherwise be a day that is not a Business
Day, the payment required to be made on such Interest Payment Date will be postponed to the next succeeding Business Day, and no interest will accrue on such payment for the period from and after such Interest Payment Date to the date of such
payment on the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on
such Interest Payment Date.

greater of: 
  

	 	(i)	100% of the principal amount of the Notes then outstanding to be redeemed, or 

  

	 	(ii)	 the sum of the present values of the remaining scheduled payments of principal and interest on the Notes then outstanding to be redeemed (not including
any

	 	 
portion of such payments of interest accrued as of the redemption date) discounted to the redemption date on a semiannual basis (computed based on a 360-day year consisting of twelve 30-day
months) at the Treasury Rate, plus 25 basis points (0.25%), as calculated by an Independent Investment Banker, 

 plus, in
either of the above cases, accrued and unpaid interest thereon to the redemption date. 
 The Company will mail a notice of
redemption at least 30 days but no more than 60 days before the redemption date to each Holder of the Notes to be redeemed. If the Company elects to partially redeem the Notes, the Trustee will select in a fair and appropriate manner the Notes to be
redeemed. 
 Unless the Company defaults in payment of the redemption price, on and after the redemption date, interest will
cease to accrue on the Notes or portions thereof called for redemption. 
 The Notes are not entitled to the benefit of any
sinking fund or analogous provision.
