	hereof.
	 
	All
	things necessary to make this Third Supplemental Indenture a valid, binding and
	enforceable agreement of the Company, and to make the 2008 Notes, when executed
	by the Company and authenticated and delivered by the Trustee, the valid

	and conditions thereof, it is mutually agreed, for the equal and proportionate
	benefit of all Holders of the 2008 Notes as follows:
	 
	ARTICLE I
	 
	GENERAL TERMS AND CONDITIONS
	OF
	THE
	2008
	NOTES
	 
	Section 1.01     There
	shall be and is hereby authorized a series of Notes designated the “7.95% Senior
	Unsecured Notes Due 2018”.  The 2008 Notes shall initially be
	authenticated and delivered in the aggregate principal amount of
	$350,000,000.  The 2008 Notes shall mature and the principal thereof
	shall be due and payable together with all accrued and unpaid interest thereon
	on May 15, 2018.  The Company may issue, without the consent of the
	Holders of the 2008 Notes, additional 2008 Notes from time to time in accordance
	with Section 3.01 hereof.  Any such additional 2008 Notes shall have
	identical terms as the 2008 Notes, unless otherwise determined by the Company
	with respect to their original date of issuance, their original interest accrual
	date, and their original Interest Payment Date.  Any such additional
	2008 Notes, together with the other 2008 Notes, shall constitute a single series
	for purposes of the Indenture.
	 
	Section 1.02     The
	2008 Notes shall be issued in fully registered form without coupons, initially
	as one or more Global Notes to and registered in the name of Cede & Co., as
	nominee of The Depository Trust Company, as Depositary therefor.  Any
	2008 Notes to be issued or transferred to, or to be held by, Cede & Co. (or
	any successor thereof) for such purpose shall bear the depositary legend in
	substantially the form set forth in the second paragraph at the top of the form
	of 2008 Note in Article II hereof (in addition to that set forth in Section 2.04
	of the Indenture), unless otherwise agreed by the Company, such agreement to be
	confirmed in writing to the Trustee.  Each such Global Note may be
	exchanged in whole or in part for a 2008 Note of the same series registered, and
	any transfer of such Global Note in whole or in part may be registered, in the
	name or names of Persons other than such Depositary or a nominee thereof only
	under the circumstances set forth in Clause (2) of the last paragraph of Section
	3.05 of the Indenture, or such other circumstances in addition to or in lieu of
	those set forth in Clause (2) of the last paragraph of Section 3.05 of the
	Indenture as to which the Company shall agree, such agreement to be confirmed in
	writing to the Trustee.
	 
	Section 1.03     Each
	2008 Note will bear interest at the rate of 7.95% per annum, from May 13, 2008
	or from the most recent Interest Payment Date (as hereinafter defined) to which
	interest has been paid or duly provided for, payable semi-annually in arrears on
	May 15 and November 15 in each year (each an “
	Interest Payment Date
	”),
	commencing November 15, 2008 until the principal thereof is paid or made
	available for payment.  The interest so payable on a 2008 Note, and
	punctually paid or duly provided for, on any Interest Payment Date will, as
	provided in the Indenture, be paid to the Person in whose name such 2008 Note or
	any Predecessor Note is registered at the close of business on the Regular
	Record Date for such interest, which shall be the second Business Day preceding
	the applicable Interest Payment Date.  Any such installment of
	interest not so punctually paid or duly provided for will forthwith cease to be
	payable to the Holder on such Regular Record Date and may either be paid to the
	Person in whose name such 2008 Note or any Predecessor Note is registered at the
	close of business on a Special Record Date for the payment of such Defaulted
	Interest to be fixed by the Trustee, notice whereof shall be given to Holders of
	the 2008 Notes not less than 10 days prior to such Special Record Date, or may
	be paid at any time in any other lawful manner not inconsistent with the
	requirements of any securities exchange on which the 2008 Notes may be listed,
	and upon such notice as may be required by such exchange, all as more fully
	provided in the Indenture.
	 
	The
	amount of interest payable on the 2008 Notes for any period will be computed on
	the basis of a 360-day year of twelve 30-day months. In the event that any
	Interest Payment Date, Redemption Date or Stated Maturity of any 2008 Note is
	not a Business Day, then payment of interest or principal (and premium, if any)
	payable on such date will be made on the next succeeding day which is a Business
	Day (and without any interest or other payment in respect of any such delay), in
	each case with the same force and effect as if made on such Interest Payment
	Date, Redemption Date or Stated Maturity, as the case may be.
	 
	As used
	in this Third Supplemental Indenture, “
	Business Day
	” means any day,
	other than (i) a Saturday or Sunday, (ii) a day on which banking institutions in
	The City of New York are authorized or required by law, regulation, or executive
	order to remain closed, or (iii) a day on which the Corporate Trust Office of
	the Trustee is closed for business.
	 
	Section 1.04     Payment
	of the principal of, and premium, if any, and interest on the 2008 Notes shall
	be payable, and registration of transfer and exchanges of the 2008 Notes may be
	effected at the office or agency of the Company maintained for that purpose in
	The City and State of New York, which shall be the Corporate Trust Office of the
	Trustee or at such other office or agency in The City of New York and State of
	New York as may be designated for such purpose by the Company from time to time;
	and such payment shall be made in such coin or currency of the United States of
	America as at the time of payment is legal tender for payment of public and
	private debts;
	provided,
	however,
	that at the option of the Company payment of interest may be
	made by check mailed to the address of the Person entitled thereto as such
	address shall appear in the Note Register.  Notices and demands to or
	upon the Company in respect of the 2008 Notes and the Indenture may be served at
	the office or agency of the Company maintained for that purpose, which initially
	shall be the Corporate Trust Office of the Trustee.
	Section
	1.05     The Company, at its option, may redeem at any
	time all, or from time to time, any part of the 2008 Notes on not less than 30
	days nor more than 60 days notice as provided in the Indenture (except that,
	notwithstanding the provisions of Section 11.04 of the Indenture, any notice of
	redemption for the 2008 Notes given pursuant to said Section need not set forth
	the Redemption Price but only the manner of calculation thereof) at a Redemption
	Price equal to the greater of the following amounts:
	 
	(i)           100%
	of the principal amount of the 2008 Notes then Outstanding to be so redeemed;
	and
	 
	(ii)          the
	sum of the present values of the principal amount and the remaining scheduled
	payments of interest on the 2008 Notes to be redeemed (not including any portion
	of payments of interest accrued as of the applicable Redemption Date),
	discounted to the applicable Redemption Date in accordance with customary market
	practice on a semi-annual basis at a rate equal to the sum of the Treasury Rate
	plus 0.60 %,
	 
	plus, in
	either of the above cases, accrued and unpaid interest on the principal amount
	being redeemed to the applicable Redemption Date.
	 
	The
	Redemption Price will be calculated by the Independent Investment Banker
	assuming a 360-day year consisting of twelve 30-day months.

	debt securities of a comparable maturity to the remaining term of such 2008
	Notes.
	 
	“
	Comparable Treasury Price

	The Wall Street Journal
	in
	the table entitled “Treasury Bonds, Notes, and Bills,” as determined by the
	Independent Investment Banker, or
	 
	(ii)           if
	such release (or any successor release) is not published or does not contain
	such prices on such Business Day:
	 
	(x)           the
	average of the Reference Treasury Dealer Quotations for that Redemption Date,
	after excluding the highest and lowest of the Reference Treasury Dealer
	Quotations,
	 
	(y)           if
	the Trustee obtains fewer than four Reference Treasury Dealer Quotations, the
	average of all Reference Treasury Dealer Quotations so received, or
	 
	(z)           if
	only one Reference Treasury Dealer Quotation is received, such
	quotation.
	 
	“
	Independent Investment Banker

	(iii) two other nationally recognized investment banking firms (or their
	affiliates) that are selected by the Company in connection with the particular
	redemption, and their respective successors, provided that if any of them ceases

	Dealer.
	 
	 “
	Reference Treasury Dealer
	Quotations
	” means, with respect to each Reference Treasury Dealer and any

	Dealer at 3:30 p.m., New York City time, on the third Business Day preceding
	that Redemption Date.
	 
	“
	Treasury Rate
	” means, with
	respect to any Redemption Date, the rate per year equal to the semi-annual

	amount) equal to the Comparable Treasury Price for that Redemption
	Date.
	 
	If less
	than all of the 2008 Notes are to be redeemed, the Trustee shall select by lot,
	on a pro-rata basis or in such other manner as it shall deem appropriate and
	fair, the particular 2008 Notes or portions thereof to be
	redeemed.  Notice of redemption shall be given by mail not less than

	a successor Depositary);
	provided, however,
	that the
	failure to duly give such notice by mail, or any defect therein, shall not
	affect the validity of any proceedings for the redemption of 2008 Notes as to
	which there shall have been no such failure or defect.  Such notice
	may state that such redemption shall be conditional upon receipt by the Paying
	Agent or Agents for such 2008 Notes, on or prior to the Redemption Date, of
	money sufficient to pay the principal of and premium, if any, and interest, if
	any, on such 2008 Notes and that if such money shall not have been so received
	such notice shall be of no force or effect and the Company shall not be required
	to redeem such 2008 Notes.  On and after the Redemption Date (unless
	the Company shall default in the payment of the 2008 Notes or portions thereof
	to be redeemed at the applicable Redemption Price, together with interest
	accrued thereon to such date), interest on the 2008 Notes or the portions
	thereof so called for redemption shall cease to accrue.
	 
	The
	Independent Investment Banker shall give to the Company and the Trustee written
	notice of the Redemption Price applicable to the 2008 Notes promptly after its
	calculation thereof.

	Trustee shall be under no duty to inquire into, may conclusively presume the
	correctness of, shall be fully protected in relying upon the Independent
	Investment Banker’s calculation of any Redemption Price, and shall have no
	responsibility for such calculation.

	fund.
