(b) Within 30 days following any Change of Control Repurchase Event or, at the Corporation’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Corporation will mail a notice to each Securityholder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and (i) offering to repurchase the Notes on the repurchase date specified in the notice, which date will be a Business Day no earlier than 30 days and no later than 60 days from the date such notice is mailed, (ii) indicating that all Notes validly tendered will be accepted for payment and any Note not tendered will continue to accrue interest, (iii) specifying the CUSIP numbers for the Notes, (iv) stating that, unless the Corporation defaults in its payment in connection with the Change of Control Repurchase Event, all Notes accepted for payment pursuant to the Corporation’s offer to repurchase such Notes will cease to accrue interest after such repurchase, (v) stating that Securityholders electing to have any Notes repurchased by the Corporation pursuant to this Section 4.03 will be required to surrender such Notes to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the repurchase date, (vi) stating that Securityholders will be entitled to withdraw their election made pursuant to this Section 4.03 if the Paying Agent receives, not later than the close of business on the second Business Day preceding the repurchase date, a facsimile transmission or letter setting forth the name of the Securityholder, the principal amount of Notes delivered for repurchase, and a statement that such Securityholder is withdrawing his election to have the Notes repurchased and (vii) stating that Securityholders whose Notes of any series are being repurchased only in part will be issued new notes of such series equal in principal amount to the unpurchased portion of the Notes surrendered, which unpurchased portion will be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

(c) The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the Corporation’s offer to repurchase is conditioned on a Change of Control Repurchase Event occurring on or prior to the repurchase date specified in the notice. The Corporation will cause its offer to purchase to remain open for at least 20 Business Days or such longer period as is required by applicable law. The Corporation will comply with the requirements of Rule 14e‑1 under the Exchange Act, and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event.

The Corporation will publicly announce the results of its offer to repurchase the Notes on or as soon as practicable after the repurchase date.

(f) The Corporation will not be required to make an offer to repurchase the Notes upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.03 applicable to an offer made by the Corporation and such third party purchases all Notes properly tendered and not withdrawn under such third party’s offer.

CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

REGIONS BANK, as Trustee

By:

Authorized Officer

Dated: March 29, 2007

This Series N Note is one of a duly authorized issue of Securities of the Corporation (the “Securities”) issued and issuable in one or more series under an Indenture, dated as of March 31, 1994, as supplemented by the Fourth Supplemental Indenture (the “Fourth Supplemental Indenture”) dated as of March 26, 2007 (collectively, the “Indenture”), between the Corporation and Regions Bank (successor-in-interest to First American Bank & Trust of Louisiana and Regions Bank of Louisiana), as trustee (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, limitation of rights, duties and immunities thereunder of the Corporation, the Trustee and the holders of the Securities issued thereunder and of the terms upon which said Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof as 6.00% Senior Notes, Series N, due 2017 (the “Series N Notes”). Such series is being initially issued in the aggregate principal amount of $500,000,000. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

The Series N Notes are redeemable, at any time in whole or from time to time in part, at the Corporation’s option, at a redemption price equal to the greater (a) of 100% of the principal amount of the Series N Notes to be redeemed; and (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Series N Notes to be redeemed (exclusive of interest accrued to the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the then current Treasury Rate plus 25 basis points. In each case the Corporation will pay any accrued and unpaid interest on the principal amount being redeemed to the date of redemption.

The Corporation will mail notice of redemption at least 30 but not more than 60 days before the redemption date to each holder of record of the Series N Notes to be redeemed at its registered address. The notice of redemption for the Series N Notes will state, among other things, the amount of Series N Notes to be redeemed, the redemption date, the redemption price and the place or places that payment will be made upon presentation and surrender of Series N Notes to be redeemed. Unless the Corporation defaults in the payment of the redemption price, interest will cease to accrue on any Series N Notes that have been called for redemption at the redemption date.

If less than all of the Series N Notes are redeemed, the Trustee will be notified at least 45 days before giving notice of redemption, or such shorter period as is satisfactory to the Trustee, of the aggregate principal amount of Series N Notes to be redeemed and the redemption date. The Trustee will select by lot, or in such other manner it deems fair and appropriate, the Series N Notes to be redeemed in part.

If the Corporation gives notice as provided in the Indenture, and funds for the redemption of any Series N Notes (or any portion thereof) called for redemption will have been made available on the redemption date referred to in such notice, those Series N Notes (or any portion thereof) will cease to bear interest on that redemption date and the only right of the holders of those Series N Notes will be to receive payment of the redemption price.

The Series N Notes are redeemable on the Special Mandatory Redemption Date at the Special Mandatory Redemption Price in the event that, for any reason, (a) the Proposed Acquisition has not been completed on or prior to July 31, 2007; or (b) the Stock Purchase Agreement is terminated (without the Proposed Acquisition being completed) on or prior to July 31, 2007.

Notice of a special mandatory redemption will be mailed promptly after the occurrence of the event triggering redemption to each holder of Series N Notes at its registered address. If funds sufficient to pay the Special Mandatory Redemption Price (including any accrued and unpaid interest) of all Series N Notes to be redeemed on the Special Mandatory Redemption Date are deposited with the Paying Agent on or before such Special Mandatory Redemption Date, on and after such Special Mandatory Redemption Date the Series N Notes will cease to bear interest.

If a Change of Control Repurchase Event occurs, unless the Corporation is required or has exercised its right to redeem the Series N Notes as described above, it will make an offer to each holder of Series N Notes to repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000) of such holder’s Series N Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of such Series N Notes repurchased plus any accrued and unpaid interest on such Series N Notes repurchased to, but not including, the date of repurchase.

Within 30 days following any Change of Control Repurchase Event or, at the Corporation’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Corporation will mail a notice to each holder of Series N Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and (i) offering to repurchase the Series N Notes on the repurchase date specified in the notice, which date will be a Business Day no earlier than 30 days and no later than 60 days from the date such notice is mailed, (ii) indicating that all Series N Notes validly tendered will be accepted for payment and any Series N Note not tendered will continue to accrue interest, (iii) specifying the CUSIP numbers for the Series N Notes, (iv) stating that, unless the Corporation defaults in its payment in connection with the Change of Control Repurchase Event, all Series N Notes accepted for payment pursuant to the Corporation’s offer to repurchase such Series N Notes will cease to accrue interest after such repurchase, (v) stating that holders electing to have any Series N Notes repurchased by the Corporation will be required to surrender such Series N Notes to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the repurchase date, (vi) stating that holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the repurchase date, a facsimile transmission or letter setting forth the name of the holder of Series N Notes, the principal amount of Series N Notes delivered for repurchase, and a statement that such holder is withdrawing his election to have the Series N Notes repurchased and (vii) stating that holders whose Series N Notes are being repurchased only in part will be issued new Series N Notes in principal amount to the unpurchased portion of the Series N Notes surrendered, which unpurchased portion will be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the Corporation’s offer to repurchase is conditioned on a Change of Control Repurchase Event occurring on or prior to the repurchase date specified in the notice. The Corporation will cause its offer to purchase to remain open for at least 20 Business Days or such longer period as is required by applicable law. The Corporation will comply with the requirements of Rule 14e‑1 under the Exchange Act, and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable in connection with the repurchase of the Series N Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Series N Notes, the Corporation will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 4.03 of the Fourth Supplemental Indenture by virtue of such conflict.

On the repurchase date following a Change of Control Repurchase Event, the Corporation will, to the extent lawful: (a) accept for payment all the Series N Notes or portions of the Series N Notes properly tendered pursuant to the Corporation’s offer; (b) deposit with the Paying Agent an amount equal to the aggregate repurchase price in respect of all the Series N Notes or portions of the Series N Notes properly tendered; and (c) deliver or cause to be delivered to the Trustee the Series N Notes properly accepted, together with an officers’ certificate stating the aggregate principal amount of Series N Notes being purchased by the Corporation.

The Paying Agent will promptly mail to each holder of Series N Notes properly tendered the repurchase price for such Series N Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new Series N Note of the same series equal in principal amount to any unpurchased portion of any Series N Notes surrendered, if any; provided that each new Series N Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Corporation will publicly announce the results of its offer to repurchase the Series N Notes on or as soon as practicable after the repurchase date.

The Corporation will not be required to make an offer to repurchase the Series N Notes upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements applicable to an offer made by the Corporation and such third party purchases all Series N Notes properly tendered and not withdrawn under such third party’s offer.

The Indenture also contains provisions permitting the holders of a majority in aggregate principal amount of the Securities of any series at the time Outstanding, on behalf of the holders of Securities of such series, to waive any past default in the performance of any of the covenants contained in the Indenture, or established pursuant to the Indenture with respect to such series, and its consequences, except a default in the payment of the principal of, or premium, if any, or interest on any of the Securities of such series. Any such consent or waiver by the registered holder of this Security (unless revoked as provided in the Indenture) shall be conclusive and binding upon such holder and upon all future holders and owners of this Security and of any Security issued in exchange hereof or in place hereof (whether by registration of transfer or otherwise), irrespective of whether or not any notation of such consent or waiver is made upon this Security.

No reference herein to the Indenture and no provision of this Series N Noteor of the Indenture shall alter or impair the obligation of the Corporation, which is absolute and unconditional, to pay the principal of and interest on this Series N Note at the times and place and at the rate and in the currency herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Series N Note is registrable in the security register, upon surrender of this Series N Note for registration of transfer at the office or agency of the Corporation for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Corporation and the security registrar and duly executed by, the holder hereof or his attorney duly authorized in writing, and thereupon one or more new Series N Notes, of this series, of authorized denominations and of like tenor and for the same aggregate principal amount, will be issued to the designated transferee or transferees. No service charge shall be made for any such registration of transfer or exchange, but the Corporation may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

As provided in and subject to the provisions of the Indenture, the holder of this Series N Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Series N Notes, the holders of not less than a majority in aggregate principal amount of the Series N Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the holders of a majority in aggregate principal amount of Series N Notes at the time Outstanding a direction inconsistent with such request and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the holder of this Series N Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

Prior to due presentment of this Series N Note for registration of transfer, the Corporation, the Trustee, any Paying Agent and any security registrar may deem and treat the Person in whose name this Series N Note is registered as the absolute owner hereof for all purposes, whether or not this Series N Note be overdue and notwithstanding the notice of ownership or writing hereon made by anyone other than the security registrar, and neither the Corporation, the Trustee nor any such agent shall be affected by notice to the contrary.

The Series N Notes are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to the limitations therein set forth, Series N Notes are exchangeable for a like aggregate principal amount of Series N Notes of a different authorized denomination, as requested by the holder surrendering the same upon surrender of the Series N Note or Notes to be exchanged at the office or agency of the Corporation.

CERTIFICATE OF AUTHENTICATION

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

REGIONS BANK, as Trustee

By:

Authorized Officer

Dated: March 29, 2007

This Series O Note is one of a duly authorized issue of Securities of the Corporation (the “Securities”) issued and issuable in one or more series under an Indenture, dated as of March 31, 1994, as supplemented by the Fourth Supplemental Indenture (the “Fourth Supplemental Indenture”) dated as of March 26, 2007 (collectively, the “Indenture”), between the Corporation and Regions Bank (successor-in-interest to First American Bank & Trust of Louisiana and Regions Bank of Louisiana), as trustee (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, limitation of rights, duties and immunities thereunder of the Corporation, the Trustee and the holders of the Securities issued thereunder and of the terms upon which said Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof as 5.50% Senior Notes, Series O, due 2013 (the “Series O Notes”). Such series is being initially issued in the aggregate principal amount of $250,000,000. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

The Series O Notes are redeemable, at any time in whole or from time to time in part, at the Corporation’s option, at a redemption price equal to the greater (a) of 100% of the principal amount of the Series O Notes to be redeemed; and (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Series O Notes to be redeemed (exclusive of interest accrued to the date of redemption), discounted to the date of redemption on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the then current Treasury Rate plus 15 basis points. In each case the Corporation will pay any accrued and unpaid interest on the principal amount being redeemed to the date of redemption.

The Corporation will mail notice of redemption at least 30 but not more than 60 days before the redemption date to each holder of record of the Series O Notes to be redeemed at its registered address. The notice of redemption for the Series O Notes will state, among other things, the amount of Series O Notes to be redeemed, the redemption date, the redemption price and the place or places that payment will be made upon presentation and surrender of Series O Notes to be redeemed. Unless the Corporation defaults in the payment of the redemption price, interest will cease to accrue on any Series O Notes that have been called for redemption at the redemption date.

If less than all of the Series O Notes are redeemed, the Trustee will be notified at least 45 days before giving notice of redemption, or such shorter period as is satisfactory to the Trustee, of the aggregate principal amount of Series O Notes to be redeemed and the redemption date. The Trustee will select by lot, or in such other manner it deems fair and appropriate, the Series O Notes to be redeemed in part.

If the Corporation gives notice as provided in the Indenture, and funds for the redemption of any Series O Notes (or any portion thereof) called for redemption will have been made available on the redemption date referred to in such notice, those Series O Notes (or any portion thereof) will cease to bear interest on that redemption date and the only right of the holders of those Series O Notes will be to receive payment of the redemption price.

If a Change of Control Repurchase Event occurs, unless the Corporation has exercised its right to redeem the Series O Notes as described above, it will make an offer to each holder of Series O Notes to repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000) of such holder’s Series O Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of such Series O Notes repurchased plus any accrued and unpaid interest on such Series O Notes repurchased to, but not including, the date of repurchase.

Within 30 days following any Change of Control Repurchase Event or, at the Corporation’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Corporation will mail a notice to each holder of Series O Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and (i) offering to repurchase the Series O Notes on the repurchase date specified in the notice, which date will be a Business Day no earlier than 30 days and no later than 60 days from the date such notice is mailed, (ii) indicating that all Series O Notes validly tendered will be accepted for payment and any Series O Note not tendered will continue to accrue interest, (iii) specifying the CUSIP numbers for the Series O Notes, (iv) stating that, unless the Corporation defaults in its payment in connection with the Change of Control Repurchase Event, all Series O Notes accepted for payment pursuant to the Corporation’s offer to repurchase such Series O Notes will cease to accrue interest after such repurchase, (v) stating that holders electing to have any Series O Notes repurchased by the Corporation will be required to surrender such Series O Notes to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the repurchase date, (vi) stating that holders will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the repurchase date, a facsimile transmission or letter setting forth the name of the holder of Series O Notes, the principal amount of Series O Notes delivered for repurchase, and a statement that such holder is withdrawing his election to have the Series O Notes repurchased and (vii) stating that holders whose Series O Notes are being repurchased only in part will be issued new Series O Notes in principal amount to the unpurchased portion of the Series O Notes surrendered, which unpurchased portion will be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the Corporation’s offer to repurchase is conditioned on a Change of Control Repurchase Event occurring on or prior to the repurchase date specified in the notice. The Corporation will cause its offer to purchase to remain open for at least 20 Business Days or such longer period as is required by applicable law. The Corporation will comply with the requirements of Rule 14e‑1 under the Exchange Act, and any other securities laws and regulations thereunder, to the extent those laws and regulations are applicable in connection with the repurchase of the Series O Notes as a result of a Change of Control Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Series O Notes, the Corporation will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 4.03 of the Supplemental Indenture by virtue of such conflict.

On the repurchase date following a Change of Control Repurchase Event, the Corporation will, to the extent lawful: (a) accept for payment all the Series O Notes or portions of the Series O Notes properly tendered pursuant to the Corporation’s offer; (b) deposit with the Paying Agent an amount equal to the aggregate repurchase price in respect of all the Series O Notes or portions of the Series O Notes properly tendered; and (c) deliver or cause to be delivered to the Trustee the Series O Notes properly accepted, together with an officers’ certificate stating the aggregate principal amount of Series O Notes being purchased by the Corporation.

The Paying Agent will promptly mail to each holder of Series O Notes properly tendered the repurchase price for such Series O Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new Series O Note of the same series equal in principal amount to any unpurchased portion of any Series O Notes surrendered, if any; provided that each new Series O Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Corporation will publicly announce the results of its offer to repurchase the Series O Notes on or as soon as practicable after the repurchase date.

The Corporation will not be required to make an offer to repurchase the Series O Notes upon a Change of Control Repurchase Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements applicable to an offer made by the Corporation and such third party purchases all Series O Notes properly tendered and not withdrawn under such third party’s offer.

As used herein:

“Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Ratings Event.

“Comparable Treasury Issue” means the U.S. Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term (the “Remaining Life”) of the Series O Notes 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 such Series O Notes.

“Exchange Act” means the Securities Exchange Act of 1934, as amended.

“Independent Investment Banker” means one of the Reference Treasury Dealers that the Corporation appoints to act as the Independent Investment Banker from time to time.

“Investment Grade” means a rating of Baa3 or better by Xxxxx’x (or its equivalent under any successor Rating Categories of Moody’s); a rating of BBB- or better by S&P (or its equivalent under any successor Rating Categories of S&P); and the equivalent investment grade credit rating from any additional Rating Agency or Rating Agencies selected by the Corporation.

“Xxxxx’x” means Xxxxx’x Investors Service Inc.

“Rating Agency” means (1) each of Moody’s and S&P; and (2) if either of Moody’s or S&P ceases to rate the Series O Notes or fails to make a rating of the Series O Notes publicly available for reasons outside of the Corporation’s control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3‑l(e)(2)(vi)(F) under the Exchange Act, selected by the Corporation (as certified by a resolution of the Corporation’s board of directors) as a replacement agency for Moody’s or S&P, or both, as the case may be.

“Rating Category” means (i) with respect to S&P, any of the following categories: XXX, XX, X, XXX, XX, X and D (or equivalent successor categories); (ii) with respect to Moody’s, any of the following categories: Baa, Ba, B, Caa, Ca, C and D (or equivalent successor categories); and (iii) the equivalent of any such category of S&P or Moody’s used by another Rating Agency. In determining whether the rating of the Series O Notes has decreased by one or more gradations, gradations within Rating Categories (+ and − for S&P; 1, 2 and 3 for Moody’s; or the equivalent gradations for another Rating Agency) shall be taken into account (e.g., with respect to S&P, a decline in a rating from BB+ to BB, as well as from BB − to B+, will constitute a decrease of one gradation).

“Ratings Event” means the occurrence of the events described in (a) or (b) below on, or within 90 days after the earlier of, (i) the occurrence of a Change of Control or (ii) public notice of the occurrence of a Change of Control or the Corporation’s intention to effect a Change of Control (which period shall be extended so long as the rating of the Series O Notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies): (a) in the event the Series O Notes are rated by both Rating Agencies on the Rating Date as Investment Grade, the rating of the Series O Notes shall be reduced so that the Series O Notes are rated below Investment Grade by both Rating Agencies, or (b) in the event the Series O Notes (1) are rated Investment Grade by one Rating Agency and below Investment Grade by the other Rating Agency on the Rating Date, the rating of the Series O Notes by either Rating Agency shall be decreased so that the Series O Notes are then rated below Investment Grade by both Rating Agencies or (2) are rated below Investment Grade by both Rating Agencies on the Rating Date, the rating of the Series O Notes by either Rating Agency shall be decreased by one or more gradations (including gradations within Rating Categories, as well as between Rating Categories). Notwithstanding the foregoing, a Ratings Event otherwise arising by virtue of a particular reduction in Rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Ratings Event for purposes of the definition of Change of Control Repurchase Event set forth above) if the Rating Agencies making the reduction in Rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Ratings Event).

“Reference Treasury Dealer” means each of Banc of America Securities LLC, X.X. Xxxxxx Securities Inc. and Xxxxxx Brothers Inc. and their respective successors, and one other firm that is a primary U.S. Government Securities dealer (each, a “Primary Treasury Dealer”) which the Corporation specifies from time to time; provided, however, that if any of them ceases to be a Primary Treasury Dealer, the Corporation will substitute another Primary Treasury Dealer.

“Regular Record Date” means, with respect to any Interest Payment Date for the Series O Notes, the March 15 and September 15 immediately preceding such Interest Payment Date.

“Treasury Rate” means, with respect to any redemption date, the rate per year equal to: (i) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue; provided that, if no maturity is within three months before or after the Remaining Life of the Series O Notesto be redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight line basis, rounding to the nearest month; or (ii) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such redemption date. The Treasury Rate will be calculated on the third business day preceding the redemption date.

The Series O Notes are not subject to, the benefit of, and do not have, any sinking fund.

In case an Event of Default, as defined in the Indenture, with respect to the Series O Notes shall have occurred and be continuing, the principal of the Series O Notes may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

No reference herein to the Indenture and no provision of this Series O Noteor of the Indenture shall alter or impair the obligation of the Corporation, which is absolute and unconditional, to pay the principal of and interest on this Series O Note at the times and place and at the rate and in the currency herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Series O Note is registrable in the security register, upon surrender of this Series O Note for registration of transfer at the office or agency of the Corporation for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Corporation and the security registrar and duly executed by, the holder hereof or his attorney duly authorized in writing, and thereupon one or more new Series O Notes, of this series, of authorized denominations and of like tenor and for the same aggregate principal amount, will be issued to the designated transferee or transferees. No service charge shall be made for any such registration of transfer or exchange, but the Corporation may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

As provided in and subject to the provisions of the Indenture, the holder of this Series O Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Series O Notes, the holders of not less than a majority in aggregate principal amount of the Series O Notes at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable indemnity, and the Trustee shall not have received from the holders of a majority in aggregate principal amount of Series O Notes at the time Outstanding a direction inconsistent with such request and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the holder of this Series O Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

Prior to due presentment of this Series O Note for registration of transfer, the Corporation, the Trustee, any Paying Agent and any security registrar may deem and treat the Person in whose name this Series O Note is registered as the absolute owner hereof for all purposes, whether or not this Series O Note be overdue and notwithstanding the notice of ownership or writing hereon made by anyone other than the security registrar, and neither the Corporation, the Trustee nor any such agent shall be affected by notice to the contrary.

No recourse shall be had for the payment of the principal of or any premium or the interest on this Series O Note, or for any claim based hereon, or otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, shareholder, affiliate, officer or director, as such, past, present or future, of the Corporation or of any predecessor or 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 issuance hereof, expressly waived and released.

The Series O Notes are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to the limitations therein set forth, Series O Notes are exchangeable for a like aggregate principal amount of Series O Notes of a different authorized denomination, as requested by the holder surrendering the same upon surrender of the Series O Note or Notes to be exchanged at the office or agency of the Corporation.

This Series O Note shall be governed by, and construed in accordance with, the internal laws of the State of Louisiana.
