REDEMPTION AND REPURCHASE

Section 3.01 Optional Redemption Procedures for the Notes . At any time before January 1, 2025, the Notes are redeemable, in whole or from time to time in part, at the Corporation’s option, at a redemption price equal to the greater of:

(a) 100% of the principal amount of the Notes to be redeemed; or

(b) the sum of the present values of the remaining scheduled payments of principal and interest on the 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 applicable to the Notes plus 50 basis points.

At any time on or after January 1, 2025, the Notes are redeemable, in whole or from time to time in part, at the Corporation’s option, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed.

In each case above, the Corporation will pay any accrued and unpaid interest on the principal amount of the Notes to be redeemed to, but not including, the date of redemption.

In addition, at any time on or prior to April 1, 2018, the Corporation may, at its option, on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes at a redemption price of 105.625% of the principal amount thereof, plus accrued and unpaid interest on the principal amount of the Notes to be redeemed to, but not including, the date of redemption, with the net cash proceeds of an Equity Offering; provided that:

(a) at least 65% of the aggregate principal amount of Notes originally issued under this Tenth Supplemental Indenture remains outstanding immediately after the occurrence of such redemption; and

(b) the redemption occurs within 90 days of the date of the closing of such Equity Offering.

21

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 Notes to be redeemed at its registered address. The notice of redemption for the Notes will state, among other things, the amount of 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 Notes to be redeemed. Unless the Corporation defaults in the payment of the redemption price, interest will cease to accrue on any Notes that have been called for redemption at the redemption date.

The Corporation may mail notice of redemption prior to the completion of any event or transaction related to such redemption, and any redemption or notice may, at the discretion of the Corporation, be subject to one or more conditions precedent, including, but not limited to, completion of an Equity Offering. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the discretion of the Corporation, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed.

If less than all of the 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 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 Notes to be redeemed in part.

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

The Corporation will notify the Trustee of the redemption price promptly after the calculation thereof, and the Trustee shall have no responsibility for such calculation. Neither the Corporation nor the Trustee shall be required to register the transfer of or exchange the Notes redeemed pursuant to this Section 3.01.

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. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes set forth in this Section 3.02, the Corporation will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 3.02 by virtue of such conflict.

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

(d) Third Party Offer . 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 3.02 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.

This 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 Tenth Supplemental Indenture (the “Tenth Supplemental Indenture”) dated as of March 19, 2015 (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 5.625% Senior Notes, Series X, due 2025 (the “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.

At any time before January 1, 2025, the Notes are redeemable, in whole or from time to time in part, at the Corporation’s option, at a redemption price equal to the greater of: (a) of 100% of the principal amount of the Notes to be redeemed; or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the 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 50 basis points. At any time on or after January 1, 2025, the Notes are redeemable, in whole or from time to time in part, at the Corporation’s option, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed. In each case the Corporation will pay any accrued and unpaid interest on the principal amount to be redeemed to, but not including, the date of redemption.

In addition, at any time on or prior to April 1, 2018, the Corporation may, at its option, on any one or more occasions redeem up to 35% of the aggregate principal amount of the Notes at a redemption price of 105.625% of the principal amount thereof, plus accrued and unpaid interest on the principal amount of the Notes to be redeemed to, but not including, the date of redemption, with the net cash proceeds of an Equity Offering; provided that (a) at least 65% of the aggregate principal amount of Notes originally issued under the Tenth Supplemental Indenture remains outstanding immediately after the occurrence of such redemption and (b) the redemption occurs within 90 days of the date of the closing of such Equity Offering.

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 Notes to be redeemed at its registered address. The notice of redemption for the Notes will state, among other things, the amount of 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 Notes to be redeemed. Unless the Corporation defaults in the payment of the redemption price, interest will cease to accrue on any Notes that have been called for redemption at the redemption date.

The Corporation may mail notice of redemption prior to the completion of any event or transaction related to such redemption, and any redemption or notice may, at the discretion of the Corporation, be subject to one or more conditions precedent, including, but not limited to,

A-5

completion of an Equity Offering. In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the discretion of the Corporation, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date so delayed.

If less than all of the 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 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 Notes to be redeemed in part.

If the Corporation gives notice as provided in the Indenture, and funds for the redemption of any Notes (or any portion thereof) called for redemption will have been made available on the redemption date referred to in such notice, those Notes (or any portion thereof) will cease to bear interest on that redemption date and the only right of the holders of those 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 Notes as described above, it will make an offer to each holder of Notes to repurchase all or any part (in excess of $2,000 and in integral multiples of $1,000 in excess thereof) of such holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of such Notes repurchased, together with any accrued and unpaid interest on such 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 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 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 and not validly withdrawn will, to the extent lawful, 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 holders electing to have any Notes repurchased by the Corporation 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 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 Notes, the principal amount of Notes delivered for repurchase, and a statement that such holder is withdrawing his election to have the Notes repurchased and (vii) stating that holders whose Notes are being repurchased only in part will be issued new Notes 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.

A-6

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. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of the Notes, the Corporation will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.02 of the Tenth 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 Notes or portions of the 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 Notes or portions of the Notes properly tendered; and (c) deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an officers’ certificate stating the aggregate principal amount of Notes being purchased by the Corporation.

The Paying Agent will promptly mail to each holder of Notes purchased under Section 3.02 of the Tenth Supplemental Indenture the repurchase price for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new Note of the same series equal in principal amount to any unpurchased portion of any Notes surrendered, if any; provided that each new 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 Notes on or as soon as practicable after the repurchase date.

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 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.

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

In case an Event of Default, as defined in the Indenture, with respect to the Notes shall have occurred and be continuing, the principal of the 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 Note or 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 Note at the times and place and at the rate and in the currency herein prescribed.

As provided in and subject to the provisions of the Indenture, the holder of this 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 Notes, the holders of not less than a majority in aggregate principal amount of the 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 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 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 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 Note is registered as the absolute owner hereof for all purposes, whether or not this 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 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 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 and herein set forth, Notes are exchangeable for a like aggregate

SECTION 4. Shelf Registration .

(a) Shelf Registration. If (i) the Company is not required to file an Exchange Offer Registration Statement or to consummate the Exchange Offer because the Exchange Offer is not permitted by applicable law or Commission policy (after the procedures set forth in Section 6(a) hereof have been complied with), (ii) for any reason the Exchange Offer is not Consummated by the Consummation Target Date, or (iii) any Holder of Transfer Restricted Securities (other than an Initial Purchaser) notifies the Company within ten Business Days following the consummation of the Exchange Offer that, based upon the written advice of counsel, (A) such Holder is prohibited by applicable law or Commission policy from participating in the Exchange Offer or (B) such Holder may not resell the Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder, then the Company shall

(x) cause to be filed a shelf registration statement pursuant to Rule 415 under the Securities Act, which may be an amendment to the Exchange Offer Registration Statement (in either event, the “Shelf Registration Statement”) on or prior to the earliest to occur of (1) the 30th day after the date on which the Company determines that it is not required to file the Exchange Offer Registration Statement, (2) the 30th day after the date on which the Company receives notice from a Holder of Transfer Restricted Securities as contemplated by clause (iii) above, and (3) the 395 ^th day after the Closing Date (or if such 395 ^th day is not a Business Day, the next succeeding Business Day) (such earliest date being the “Shelf Filing Deadline”), which Shelf Registration Statement shall provide for resales of all Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof; and

(y) use their commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission on or before the 90th day after the Shelf Filing Deadline (or if such 90th day is not a Business Day, the next succeeding Business Day).

-5-

The Company shall use its commercially reasonable efforts to keep such Shelf Registration Statement continuously effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of Initial Securities or Exchange Securities by the Holders of Transfer Restricted Securities entitled to the benefit of this Section 4(a), and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the written policies, rules and regulations of the Commission as announced from time to time, for a period of at least one year following the effective date of such Shelf Registration Statement (or such shorter period that will terminate when all the Initial Securities or Exchange Securities covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement).

(b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement. No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Company in writing, within ten Business Days after receipt of a request therefor, such information as the Company may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. Each Holder as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Company all information required to be disclosed in order to make the information previously furnished to the Company by such Holder not materially misleading.

SECTION 5. Additional Interest. (a) If (i) the Exchange Offer is not Consummated on or prior to the Consummation Target Date, (ii) the Shelf Registration Statement, if required pursuant to Section 4(a) hereof, has not become effective on or prior to the date specified in Section 4(a)(y), or (iii) the Shelf Registration Statement is filed and declared effective but shall thereafter cease to be effective or fail to be usable for its intended purpose without the Company curing such failure by causing a post-effective amendment to such Registration Statement to be filed and declared effective within 45 days (each such event referred to in clauses (i) through (iii), a “Registration Default”), the Company hereby agrees that the interest rate borne by the Transfer Restricted Securities shall be increased by 0.25% per annum during the 90-day period immediately following the occurrence of any Registration Default and shall increase by 0.25% per annum at the end of each subsequent 90-day period, but in no event shall such increase exceed 0.50% per annum (“Additional Interest”). Upon the earlier of (i) the date all Registration Defaults relating to any particular Transfer Restricted Securities have been cured or (ii) the date of which all the Notes and Exchange Notes otherwise cease to be Registrable Securities, the interest rate borne by the relevant Transfer Restricted Securities will be reduced to the original interest rate borne by such Transfer Restricted Securities; provided, however, that, if after any

-6-

such reduction in interest rate, a different Registration Default occurs, the interest rate borne by the relevant Transfer Restricted Securities shall again be increased pursuant to the foregoing provisions.

(b) If at any time more than one Registration Default has occurred and is continuing, then, until the next date that there is no Registration Default, the increase in interest rate provided for by Section 5(a) shall apply as if there occurred a single Registration Default that begins on the date that the earliest such Registration Default occurred and ends on such next date that there is no Registration Default. Any increase in interest will be payable in cash semiannually in arrears on the same interest payment dates as the Initial Securities and in the same manner as is specified in the Indenture, commencing with the first interest payment occurring after any such Additional Interest commences to accrue.

(c) All obligations of the Company set forth in Section 5(a) hereof that are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations under Section 5(a) with respect to such security shall have been satisfied in full. Notwithstanding anything contained herein or in the Indenture to the contrary, the payment of Additional Interest shall be the only remedy available to Holders for any Registration Default. Notwithstanding any other provision of this Agreement, a Holder of Registrable Securities who does not comply with the provisions of Section 4(b) hereof, if applicable, shall not be entitled to receive Additional Interest unless and until such Holder complies with the provisions of such section, if applicable.

SECTION 6. Registration Procedures .

(a) Exchange Offer Registration Statement. In connection with the Exchange Offer, the Company shall comply with all of the provisions of Section 6(c) hereof, shall use its commercially reasonable efforts to effect such exchange to permit the sale of Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and shall comply with all of the following provisions:

(i) If in the reasonable opinion of counsel to the Company there is a question as to whether the Exchange Offer is permitted by applicable law, the Company hereby agrees to seek a no-action letter or other favorable decision from the Commission allowing the Company to Consummate an Exchange Offer for the Initial Securities. The Company hereby agrees to pursue the issuance of such a decision by the staff of the Commission but shall not be required to take commercially unreasonable action to effect a change of Commission policy. The Company hereby agrees, however, to (A) participate in telephonic conferences with the Commission, (B) deliver to the Commission staff an analysis prepared by counsel to the Company setting forth the legal bases, if any, upon which such counsel has concluded that such an Exchange Offer should be permitted and (C) diligently pursue a favorable resolution by the Commission staff of such submission.

(ii) As a condition to its participation in the Exchange Offer pursuant to the terms of this Agreement, each Holder of Transfer Restricted Securities shall furnish, upon the request of the Company, prior to the Consummation thereof, a written representation

-7-

to the Company (which may be contained in the letter of transmittal contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an affiliate of the Company, (B) it is not engaged in, and does not intend to engage in, and has no arrangement or understanding with any Person to participate in, a distribution of the Exchange Securities to be issued in the Exchange Offer and (C) it is acquiring the Exchange Securities in its ordinary course of business. In addition, all such Holders of Transfer Restricted Securities shall otherwise cooperate in the Company’s preparations for the Exchange Offer. Each Holder hereby acknowledges and agrees that any Broker-Dealer and any such Holder using the Exchange Offer to participate in a distribution of the securities to be acquired in the Exchange Offer (1) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling (dated July 2, 1993), and similar no-action letters (which may include any no-action letter obtained pursuant to clause (i) above), and (2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction and that such a secondary resale transaction should be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange Securities obtained by such Holder in exchange for Initial Securities acquired by such Holder directly from the Company.

(b) Shelf Registration Statement. In connection with the Shelf Registration Statement, the Company shall comply with all the provisions of Section 6(c) hereof and shall use its commercially reasonable efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and pursuant thereto the Company will as expeditiously as possible prepare and file with the Commission a Registration Statement relating to the registration on any appropriate form under the Securities Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the intended method or methods of distribution thereof.

(c) General Provisions. In connection with any Registration Statement and any Prospectus required by this Agreement to permit the sale or resale of Transfer Restricted Securities (including, without limitation, any Registration Statement and the related Prospectus required to permit resales of Initial Securities by Broker-Dealers), the Company shall, subject to Section 5(d) hereof:

(ii) use its commercially reasonable efforts to prepare and file with the Commission such amendments and post-effective amendments to the applicable Registration Statement as may be necessary to keep the Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof, as applicable, or such shorter period as will terminate when all Transfer Restricted Securities covered by such Registration Statement have been sold; cause the Prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable provisions of Rules 424 and 430A under the Securities Act in a timely manner; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the Prospectus;

If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or blue sky laws, the Company shall use its commercially reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time;

The objection of such Holder or underwriter, if any, shall be deemed to be reasonable if such Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be filed, contains a material misstatement or omission;

(v) promptly prior to the filing of any document that is to be incorporated by reference into a Registration Statement or Prospectus, provide copies of such document to each selling Holder named in any Registration Statement who requests such document in writing, and to the underwriter(s), if any, and make the Company’s representatives available for discussion of such document prior to the filing thereof;

(C) deliver such other documents and certificates as may be reasonably requested by such parties to evidence compliance with Section 6(c)(xi)(A) hereof and with any customary conditions contained in the underwriting agreement or other agreement entered into by the Company pursuant to this Section 6(c)(xi), if any.

If at any time the representations and warranties of the Company contemplated in Section 6(c)(xi)(A)(1) hereof cease to be true and correct in any material respect, the Company shall so advise the underwriter(s), if any, and each selling Holder named in any Registration Statement promptly and, if requested by such Persons, shall confirm such advice in writing;

(xii) prior to any public offering of Transfer Restricted Securities, cooperate with the selling Holders named in any Registration Statement, the underwriter(s), if any, and their respective counsel in connection with the registration and qualification of the Transfer Restricted Securities under the state securities or blue sky laws of such jurisdictions as the selling Holders or underwriter(s), if any, may reasonably request in writing and do any and all other acts or things necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf Registration Statement; provided, however , that the Company shall not be required to register or qualify as a foreign corporation where it is not then so qualified or to take any action that would subject it to the service of process in suits or to taxation, other than as to matters and transactions relating to the Registration Statement, in any jurisdiction where it is not then so subject;

(xiii) use its commercially reasonable efforts to cause the Transfer Restricted Securities covered by the Registration Statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof or the underwriter(s), if any, to consummate the disposition of such Transfer Restricted Securities, subject to the proviso contained in Section 6(c)(xii) hereof;

-12-

(xiv) if any fact, condition or event contemplated by Section 6(c)(iii)(D) hereof shall exist or have occurred and remain in effect, prepare a supplement or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading;

(xv) provide a CUSIP number for all Initial Securities and Exchange Securities not later than the effective date of the Registration Statement covering such Initial Securities and Exchange Securities and provide the Trustee under the Indenture with printed certificates for such Initial Securities and Exchange Securities which are in a form eligible for deposit with the Depository Trust Company and take all other action necessary to ensure that all such Initial Securities and Exchange Securities are eligible for deposit with The Depository Trust Company;

(xvi) cooperate and assist in any filings required to be made with FINRA and in the performance of any due diligence investigation by any underwriter (including any “qualified independent underwriter”) that is required to be retained in accordance with the rules and regulations of FINRA;

(xvii) otherwise use its commercially reasonable efforts to comply with all applicable rules and regulations of the Commission, and make generally available to its security holders, as soon as practicable, a consolidated earnings statement meeting the requirements of Rule 158 (which need not be audited) for the twelve-month period (A) commencing at the end of any fiscal quarter in which Transfer Restricted Securities are sold to underwriters in a firm commitment or best efforts Underwritten Offering or (B) if not sold to underwriters in such an offering, beginning with the first month of the Company’s first fiscal quarter commencing after the effective date of the Registration Statement; and

(xix) cause the Indenture to be qualified under the Trust Indenture Act not later than the effective date of the first Registration Statement required by this Agreement, and, in connection therewith, cooperate with the Trustee and the Holders to effect such changes to the Indenture as may be required for such Indenture to be so qualified in accordance with the terms of the Trust Indenture Act; and to execute and use its commercially reasonable efforts to cause the Trustee to execute, all documents that may be required to effect such changes and all other forms and documents required to be filed with the Commission to enable such Indenture to be so qualified in a timely manner.

(d) Permitted Delays . Each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of any notice from the Company (i) of the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof or (ii) that the Board of Directors of the Company has a bona fide business purpose for doing so, such Holder will forthwith discontinue disposition of Transfer Restricted Securities pursuant to the applicable Registration Statement until such

-13-

Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xiv) hereof, or until it is advised in writing (the “Advice”) by the Company that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. If so directed by the Company, each Holder will deliver to the Company (at the Company’s expense) all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such notice. In the event the Company shall give any such notice, the time period regarding the effectiveness of such Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 6(c)(iii)(D) or this Section 6(d) to and including the date when each selling Holder covered by such Registration Statement shall have received the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xiv) hereof or shall have received the Advice; provided, however, that no such extension shall be taken into account in determining whether (1) a Registration Default has occurred pursuant to Section 5 hereof or (2) Additional Interest is due pursuant to Section 5 hereof or the amount of such Additional Interest.

SECTION 7. Registration Expenses .

(a) All expenses incident to the Company’s performance of or compliance with this Agreement will be borne by the Company, regardless of whether a Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees and expenses (including filings made by any Initial Purchaser or Holder with FINRA (and, if applicable, the fees and expenses of any “qualified independent underwriter” and its counsel that may be required by the rules and regulations of FINRA)); (ii) all fees and expenses of compliance with federal securities and state securities or blue sky laws; (iii) all expenses of printing (including printing certificates for the Exchange Securities to be issued in the Exchange Offer and printing of Prospectuses), messenger and delivery services and telephone communications; (iv) all fees and disbursements of counsel for the Company and, subject to Section 7(b) hereof, the Holders of Transfer Restricted Securities; (v) all application and filing fees in connection with listing the Exchange Securities on a securities exchange or automated quotation system pursuant to the requirements thereof; and (vi) all fees and disbursements of independent certified public accountants of the Company (including the expenses of any special audit and comfort letters required by or incident to such performance).

The Company will, in any event, bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Company.

(b) In connection with any Registration Statement required by this Agreement (including, without limitation, the Exchange Offer Registration Statement and the Shelf Registration Statement), the Company will reimburse the Holders of Transfer Restricted Securities being tendered in the Exchange Offer or resold pursuant to the “Plan of Distribution” contained in the Exchange Offer Registration Statement or registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one counsel as may be chosen by the Holders of a majority in principal amount of the Transfer Restricted Securities for whose benefit such Registration Statement is being prepared.

SECTION 8. Indemnification .

(a) The Company will indemnify and hold harmless (i) each Holder and (ii) each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the Persons referred to in this clause (ii) being hereinafter referred to as a “controlling person”) and (iii) the respective officers, directors, partners, employees and agents of any Holder or any controlling person (any Person referred to in clause (i), (ii) or (iii) may hereinafter be referred to as an “Indemnified Holder”), against any losses, claims, damages or liabilities, joint or several, to which such Indemnified Holder may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon, any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto), or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading and will reimburse each such Indemnified Holder for any legal or other expenses reasonably incurred by such Indemnified Holder in connection with investigating or defending any such action or claim as such expenses are incurred; provided , however , that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Registration Statement or Prospectus, or any such amendment or supplement, in reliance upon and in conformity with information relating to any of the Holders furnished to the Company in writing by any of the Holders expressly for use therein.

(b) Each Holder of Transfer Restricted Securities, severally, but not jointly, will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in such Registration Statement or Prospectus, or any such amendment or supplement, in reliance upon and in conformity with information relating to such Holder furnished to the Company in writing by such Holder expressly for use therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the

-15-

indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve the indemnifying party from any liability which it may have to any indemnified party under such subsection unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights or defenses and (ii) will not, in any event, relieve the indemnifying party from any obligation to any indemnified party otherwise than under the indemnification obligation provided under subsection (a) or (b) above. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation unless (x) the indemnifying party and such indemnified party shall have mutually agreed to the employment of such counsel, (y) the named parties to any such action (including any impleaded parties) include both such indemnified party and the indemnifying party and such indemnified party shall have been advised by such counsel that a conflict of interest between the indemnifying party and such indemnified party may arise and for this reason it is not desirable for the same counsel to represent both the indemnifying party and also the indemnified party and (z) such indemnified party has reasonably concluded that there are or likely may be legal defenses available to the indemnified party that are different from or in addition to those available to the indemnifying party (it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys for all such indemnified parties), in each of which cases the fees and expenses of such counsel shall be at the expense of the indemnifying party. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (B) does not include any statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) of this Section 8 in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Holders on the other from the Initial Placement (which in the case of the Company shall be deemed to be equal to the total gross proceeds to the Company

-16-

from the Initial Placement) and the Registration Statement which resulted in such losses, claims, damages, liabilities, judgments, actions or expenses. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under subsection (c) of this Section 8 and the indemnifying party has been prejudiced in any material respect by such failure, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and the Holders on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or such Holders on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and each Holder of Transfer Restricted Securities agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 8(d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), none of the Holders (and its related Indemnified Holders) shall be required to contribute, in the aggregate, any amount in excess of the discount received by such Holder with respect to the Securities. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Holders in this Section 8(d) to contribute are several in proportion to the respective principal amount of Securities held by each of the Holders hereunder and not joint.

SECTION 9. Reserved.

SECTION 10. Participation in Underwritten Registrations . No Holder may participate in any Underwritten Registration hereunder unless such Holder (a) agrees to sell such Holder’s Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements.

-17-

SECTION 11. Selection of Underwriters . The Holders of Transfer Restricted Securities covered by the Shelf Registration Statement who desire to do so may sell such Transfer Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the investment banker(s) and managing underwriter(s) that will administer such offering will be selected by the Holders of a majority in aggregate principal amount of the Transfer Restricted Securities included in such offering; provided, however , that such investment banker(s) and managing underwriter(s) must be reasonably satisfactory to the Company and will be compensated by the Holders of Transfer Restricted Securities.

SECTION 12. Miscellaneous .

(a) Remedies . The Company hereby agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agree to waive the defense in any action for specific performance that a remedy at law would be adequate.

(b) No Inconsistent Agreements . The Company will not on or after the date of this Agreement enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. Since January 1, 2010, the Company has not entered into any agreement granting any registration rights with respect to its securities to any Person. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Company’s securities under any agreement in effect on the date hereof.

(c) Amendments and Waivers . The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless the Company has (i) in the case of Section 5 hereof and this Section 12(c)(i), obtained the written consent of Holders of all outstanding Transfer Restricted Securities and (ii) in the case of all other provisions hereof, obtained the written consent of Holders of a majority of the outstanding principal amount of Transfer Restricted Securities (excluding any Transfer Restricted Securities held by the Company or its Affiliates). Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of Holders whose securities are being tendered pursuant to the Exchange Offer and that does not affect directly or indirectly the rights of other Holders whose securities are not being tendered pursuant to such Exchange Offer may be given by the Holders of a majority of the outstanding principal amount of Transfer Restricted Securities being tendered or registered; provided, however, that, with respect to any matter that directly or indirectly affects the rights of any Initial Purchaser hereunder, the Company shall obtain the written consent of each such Initial Purchaser with respect to which such amendment, qualification, supplement, waiver, consent or departure is to be effective.

(d) Notices . All notices and other communications provided for or permitted hereunder shall be made in writing by hand-delivery, first-class mail (registered or certified, return receipt requested), telex, telecopier, or air courier guaranteeing overnight delivery:
