		Authorized Signatory

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”) issued or to be issued in one or more series under an indenture dated as of August 3, 2001 (herein called the “Indenture”) between the Company and SunTrust Bank, as trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties, obligations and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, initially limited in aggregate principal amount to $400,000,000. The Company may, without the consent of the Holders of the Securities, issue additional Securities having the same ranking and same interest rate, maturity and other terms as the Securities. Any additional Securities having such similar terms, together with the Securities, will constitute a single series of Securities under the Indenture.

The Securities of this series are subject to redemption upon not less than 30 nor more than 60 days’ notice by mail, such 30 or 60 days, as the case may be, to be counted from the date notice is mailed, as a whole or in part, at the election of the Company, at a Redemption Price equal to the greater of: (1) 100% of the principal amount of Securities then outstanding, or (2) 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 Redemption Date) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate (as defined below), plus 30 basis points, as calculated by an Independent Investment Banker (as defined below); plus, in either of the above cases, accrued and unpaid interest thereon to the Redemption Date, but interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Regular Record Dates or Special Record Dates referred to on the face hereof, all as provided in the Indenture.

The Adjusted Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

“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 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 the Securities (“Remaining Life”).

“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 the Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the 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 the Independent Investment Banker at 5:00 p.m., New York City time, on the third business day preceding such Redemption Date.

The interest rate payable on the Securities will be subject to adjustment from time to time after the occurrence of any Change of Control if the debt rating applicable to the Securities (a “rating”) by either Moody’s Investors Service, Inc., (“Moody’s”), or Standard & Poor’s Ratings Services, a division of McGraw-Hill, Inc. (“S&P”) is as set forth below.

If, at any time after a Change of Control occurs, the rating of the Securities from Moody’s is a rating set forth in the immediately following table, the interest rate on the Securities will increase from that set forth on the face of this Security by the percentage set opposite that rating:

If, at any time after a Change of Control occurs, the rating of the Securities from S&P is a rating set forth in the immediately following table, the interest rate on the Securities will increase from that set forth on the face of this Security by the percentage set opposite that rating:

If Moody’s or S&P subsequently increases its rating to any of the threshold ratings set forth above, the interest rate on the Securities will be decreased such that the interest rate equals the interest rate set forth on the face of this Security plus the percentages set opposite the ratings from the tables above in effect immediately following the increase. Each adjustment required by any decrease or increase in a rating set forth above, whether occasioned by the action of Moody’s or S&P, shall be made independent of any and all other adjustments. In no event shall (1) the interest rate for the Securities be reduced to below the interest rate set forth on the face of this Security, and (2) the total increase in the interest rate exceed 2.00% above the interest rate set forth on the face of this Security. If, following any Change of Control, Moody’s increases its rating to Baa2 and S&P increases its rating to BBB, the interest rate on the Securities will remain at, or be decreased to, as the case may be, the interest rate set forth on the face of this Security and no subsequent downgrades in a rating shall result in an adjustment of the interest rate on the Securities as provided herein.

If either Moody’s or S&P ceases to provide a rating, any subsequent increase or decrease in the interest rates of the Securities necessitated by a reduction or increase in the rating by the agency continuing to provide the rating shall be twice the percentage set forth in the applicable table above. No adjustments in the interest rates of the Securities shall be made solely as a result of either Moody’s or S&P ceasing to provide a rating. If both Moody’s and S&P cease to provide a rating and a Change of Control has occurred, the interest rates on the Securities will increase to, or remain at, as the case may be, 2.00% above the interest rate set forth on the face of this Security.

Any interest rate increase or decrease, as described above, will take effect as of the most recent Interest Payment Date, or if prior to the occurrence of the first Interest Payment Date following the issuance of this Security, from and including the date of issuance of this Security. The Company shall give the Trustee a notice in writing should the interest rate on the Securities be required to be increased or decreased pursuant to the terms described above no later than the Business Day immediately following the date on which a change in the interest rate is required to be made as provided above.

“Public Acquirer” means any person whose securities (or depositary receipts respect thereof), or the securities of its direct or indirect parent, are listed or quoted on any national securities exchange or The NASDAQ National Market or, in the case of any non-U.S. organized person, if such securities are listed on any internationally recognized securities exchange.

“Voting Stock” as applied to stock of any person, means shares, interests, participations or other equivalents in the equity interest (however designated) in such person having ordinary voting power for the election of a majority of the directors (or the equivalent) of such person, other than shares, interests, participations or other equivalents having such power only by reason of the occurrence of a contingency.

The Securities do not have the benefit of any sinking fund obligations. In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security and/or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in 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 declared due and payable in the manner and with the effect provided in the Indenture. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be adversely affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be adversely affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision 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 any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities of this series are issuable only in registered form without coupons in minimum aggregate principal amounts of $2,000 or integral multiples of $1,000 for amounts in excess of $2,000. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

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.

No recourse shall be had for the payment of the principal of (or premium, if any) or the interest on this Security, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture or any indenture supplemental thereto, against any incorporator, stockholder, officer, director or employee, as such, past, present or future, of the Company or any successor corporation, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, all such liability being, by the acceptance hereof and as part of the consideration for the issue hereof, expressly waived and released.

Prior to due presentment of this Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes (subject to Section 307 of the Indenture), whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture. The Indenture and this Security shall be governed by and construed in accordance with the laws of the State of New York without regard to the conflicts of laws principles thereof.
