If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided , that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date (as defined below) by Holders of the requisite principal amount of Outstanding Securities on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect). Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Securities in the manner set forth in Section 1.6 .

     (g) The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration or rescission or annulment thereof referred to in Section 5.2 , (iii) any request to institute proceedings referred to in Section 5.7(b) or (iv) any direction referred to in Section 5.12 . If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided , that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be canceled and of no effect). Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities in the manner set forth in Section 1.6 .

     (h) With respect to any record date set pursuant to paragraph (f) or (g) of this Section 1.4 , the party hereto that sets such record date may designate any day as the “ Expiration Date ” and from time to time may change the Expiration Date to any earlier or later day; provided , that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto in writing, and to each Holder of Securities in the manner set forth in Section 1.6 , on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to this Section 1.4 , the party hereto that set such record date shall be deemed to have initially designated the ninetieth (90 ^th ) day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date

as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the one hundred and eightieth (180 ^th ) day after the applicable record date.

     SECTION 1.5. Notices, Etc.

     Any request, demand, authorization, direction, notice, consent, waiver, Act of Holders, or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with:

If, by reason of the suspension of or irregularities in regular mail service or for any other reason, it shall be impossible or impracticable to mail notice of any event to Holders when said notice is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to the Trustee shall be deemed to be a sufficient giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

     (b) Interest and Additional Interest on any Security that is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, except that interest and any Additional Interest payable on the Stated Maturity (or any date of principal repayment upon early maturity) of the principal of a Security or on a Redemption Date shall be paid to the Person to whom principal is paid. The initial payment of interest on any Security that is issued between a Regular Record Date and the related Interest Payment Date shall be payable as provided in such Security.

     (c) Any interest on any Security that is due and payable, but is not timely paid or duly provided for, on any Interest Payment Date for Securities (herein called “ Defaulted Interest ”) shall forthwith cease to be payable to the registered Holder on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in paragraph (i) or (ii) below:

     (i) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered at the close of business on a special record date for the payment of such Defaulted Interest (a “ Special Record Date ”), which shall be fixed in the following manner. At least thirty (30) days prior to the date of the proposed payment, the Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest, which shall be not more than fifteen (15) days and not less than ten (10) days prior to the date of the proposed payment and not less than ten (10) days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first class, postage prepaid, to each Holder of a Security at the address of such Holder as it appears in the Securities Register not less than ten (10) days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities (or their respective Predecessor Securities) are registered on such Special Record Date; or

     (ii) The Company may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Securities may be listed, traded or quoted and, upon such notice as may be required by such exchange or automated quotation system (or by the Trustee if the Securities are not listed), if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such payment shall be deemed practicable by the Trustee.

     (d) Payments of interest on the Securities shall include interest accrued to but excluding the respective Interest Payment Dates. The amount of interest payable for any interest period shall be computed and paid on the basis of a 360-day year and the actual number of days elapsed in the relevant interest period.

     (e) Payment of principal of, premium, if any, and interest on the Securities shall be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Payments of principal, premium, if any, and

interest due at the Maturity of such Securities shall be made at the Place of Payment upon surrender of such Securities to the Paying Agent and payments of interest shall be made subject to such surrender where applicable, by wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Paying Agent at least ten (10) Business Days prior to the date for payment by the Person entitled thereto unless proper written wire transfer instructions have not been received by the relevant record date, in which case such payments shall be made by check mailed to the address of such Person as such address shall appear in the Security Register. Notwithstanding the foregoing, so long as the holder of the Security is the Property Trustee, the payment of the principal of (and premium if any) and interest (including any overdue installment of interest and Additional Tax Sums, if any) on the Security will be made at such place and to such account as may be designated by the Property Trustee.

     (f) Subject to the foregoing provisions of this Section 3.1 , each Security delivered under this Indenture upon transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, that were carried by such other Security.

     SECTION 3.2. Denominations.

     The Securities shall be in registered form without coupons and shall be issuable in minimum denominations of $100,000 and any integral multiple of $1,000 in excess thereof.

     SECTION 3.3. Execution, Authentication, Delivery and Dating.

     (a) At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver Securities in an aggregate principal amount (including all then Outstanding Securities) not in excess of $20,619,000 executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and shall be fully protected in relying upon:

     (i) a copy of any Board Resolution relating thereto; and

     (ii) an Opinion of Counsel stating that (1) such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles; (2) the Securities have been duly authorized and executed by the Company and have been delivered to the Trustee for authentication in accordance with this Indenture; and (3) the Securities are not required to be registered under the Securities Act.

     (b) The Securities shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its Chief Executive Officer, its President or one of its

Vice Presidents. The signature of any of these officers on the Securities may be manual or facsimile. Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

     (c) No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by the manual signature of one of its authorized officers, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.8 , for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture.

     (d) Each Security shall be dated the date of its authentication.

     SECTION 3.4. Global Securities.

     (a) Upon the election of the Holder after the Original Issue Date, which election need not be in writing, the Securities owned by such Holder shall be issued in the form of one or more Global Securities registered in the name of the Depositary or its nominee. Each Global Security issued under this Indenture shall be registered in the name of the Depositary designated by the Company for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture.

     (b) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for registered Securities, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (i) such Depositary advises the Trustee and the Company in writing that such Depositary is no longer willing or able to properly discharge its responsibilities as Depositary with respect to such Global Security, and no qualified successor is appointed by the Company within ninety (90) days of receipt by the Company of such notice, (ii) such Depositary ceases to be a clearing agency registered under the Exchange Act and no successor is appointed by the Company within ninety (90) days after obtaining knowledge of such event, (iii) the Company executes and delivers to the Trustee a Company Order stating that the Company elects to terminate the book-entry system through the Depositary or (iv) an Event of Default shall have occurred and be continuing. Upon the occurrence of any event specified in clause (i), (ii), (iii) or (iv) above, the Trustee shall notify the Depositary and instruct the Depositary to notify all owners of beneficial interests in such Global Security of the occurrence of such event and of the availability of Securities to such owners of beneficial interests requesting the same. Upon the issuance of such Securities and the registration in the Securities Register of such Securities in the names of the Holders of the beneficial interests therein, the Trustees shall recognize such holders of beneficial interests as Holders.

     (c) If any Global Security is to be exchanged for other Securities or canceled in part, or if another Security is to be exchanged in whole or in part for a beneficial interest in any Global Security, then either (i) such Global Security shall be so surrendered for exchange or cancellation as provided in this Article III or (ii) the principal amount thereof shall be reduced or increased by an amount equal to the portion thereof to be so exchanged or canceled, or equal to the principal amount of such other Security to be so exchanged for a beneficial interest therein, as the case may be, by means of an appropriate adjustment made on the records of the Securities Registrar, whereupon the Trustee, in accordance with the Applicable Depositary Procedures, shall instruct the Depositary or its authorized representative to make a corresponding adjustment to its records. Upon any such surrender or adjustment of a Global Security by the Depositary, accompanied by registration instructions, the Company shall execute and the Trustee shall authenticate and deliver any Securities issuable in exchange for such Global Security (or any portion thereof) in accordance with the instructions of the Depositary. The Trustee shall not be liable for any delay in delivery of such instructions and may conclusively rely on, and shall be fully protected in relying on, such instructions.

     (d) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Security or any portion thereof shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered in the name of a Person other than the Depositary for such Global Security or a nominee thereof.

     (e) Securities distributed to holders of Book-Entry Preferred Securities (as defined in the Trust Agreement) upon the dissolution of the Trust shall be distributed in the form of one or more Global Securities registered in the name of a Depositary or its nominee, and deposited with the Securities Registrar, as custodian for such Depositary, or with such Depositary, for credit by the Depositary to the respective accounts of the beneficial owners of the Securities represented thereby (or such other accounts as they may direct). Securities distributed to holders of Preferred Securities other than Book-Entry Preferred Securities upon the dissolution of the Trust shall not be issued in the form of a Global Security or any other form intended to facilitate book-entry trading in beneficial interests in such Securities.

     (f) The Depositary or its nominee, as the registered owner of a Global Security, shall be the Holder of such Global Security for all purposes under this Indenture and the Securities, and owners of beneficial interests in a Global Security shall hold such interests pursuant to the Applicable Depositary Procedures. Accordingly, any such owner’s beneficial interest in a Global Security shall be shown only on, and the transfer of such interest shall be effected only through, records maintained by the Depositary or its nominee or its Depositary Participants. The Securities Registrar and the Trustee shall be entitled to deal with the Depositary for all purposes of this Indenture relating to a Global Security (including the payment of principal and interest thereon and the giving of instructions or directions by owners of beneficial interests therein and the giving of notices) as the sole Holder of the Security and shall have no obligations to the owners of beneficial interests therein. Neither the Trustee nor the Securities Registrar shall have any liability in respect of any transfers effected by the Depositary.

     (g) The rights of owners of beneficial interests in a Global Security shall be exercised only through the Depositary and shall be limited to those established by law and agreements between such owners and the Depositary and/or its Depositary Participants.

     (h) No holder of any beneficial interest in any Global Security held on its behalf by a Depositary shall have any rights under this Indenture with respect to such Global Security, and such Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the owner of such Global Security for all purposes whatsoever. None of the Company, the Trustee nor any agent of the Company or the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests of a Global Security or maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by a Depositary or impair, as between a Depositary and such holders of beneficial interests, the operation of customary practices governing the exercise of the rights of the Depositary (or its nominee) as Holder of any Security.

     SECTION 3.5. Registration, Transfer and Exchange Generally.

     (a) The Trustee shall cause to be kept at the Corporate Trust Office a register (the “ Securities Register ”) in which the registrar and transfer agent with respect to the Securities (the “ Securities Registrar ”), subject to such reasonable regulations as it may prescribe, shall provide for the registration of Securities and of transfers and exchanges of Securities. The Trustee shall at all times also be the Securities Registrar. The provisions of Article VI shall apply to the Trustee in its role as Securities Registrar.

     (b) Subject to compliance with Section 2.2(b) , upon surrender for registration of transfer of any Security at the offices or agencies of the Company designated for that purpose the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of any authorized denominations of like tenor and aggregate principal amount.

     (c) At the option of the Holder, Securities may be exchanged for other Securities of any authorized denominations, of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and upon receipt thereof the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to receive.

     (d) All Securities issued upon any transfer or exchange of Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange.

     (e) Every Security presented or surrendered for transfer or exchange shall (if so required by the Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Securities Registrar, duly executed by the Holder thereof or such Holder’s attorney duly authorized in writing.

     (f) No service charge shall be made to a Holder for any transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other

governmental charge that may be imposed in connection with any transfer or exchange of Securities.

     (g) Neither the Company nor the Trustee shall be required pursuant to the provisions of this Section 3.5 (i) to issue, register the transfer of or exchange any Security during a period beginning at the opening of business fifteen (15) days before the day of selection for redemption of Securities pursuant to Article XI and ending at the close of business on the day of mailing of the notice of redemption or (ii) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except, in the case of any such Security to be redeemed in part, any portion thereof not to be redeemed.

     (h) The Company shall designate an office or offices or agency or agencies where Securities may be surrendered for registration or transfer or exchange. The Company initially designates the Corporate Trust Office as its office and agency for such purposes. The Company shall give prompt written notice to the Trustee and to the Holders of any change in the location of any such office or agency.

     SECTION 3.6. Mutilated, Destroyed, Lost and Stolen Securities.

     (a) If any mutilated Security is surrendered to the Trustee together with such security or indemnity as may be required by the Company or the Trustee to save each of them harmless, the Company shall execute and upon receipt thereof the Trustee shall authenticate and deliver in exchange therefor a new Security of like tenor and aggregate principal amount and bearing a number not contemporaneously outstanding.

     (b) If there shall be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them harmless, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a bona fide purchaser, the Company shall execute and upon its written request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of like tenor and aggregate principal amount as such destroyed, lost or stolen Security, and bearing a number not contemporaneously outstanding.

     (c) If any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

     (d) Upon the issuance of any new Security under this Section 3.6 , the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

     (e) Every new Security issued pursuant to this Section 3.6 in lieu of any mutilated, destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities duly issued hereunder.

     (f) The provisions of this Section 3.6 are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

     SECTION 3.7. Persons Deemed Owners.

     The Company, the Trustee and any agent of the Company or the Trustee shall treat the Person in whose name any Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any interest on such Security and for all other purposes whatsoever, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

     SECTION 3.8. Cancellation.

     All Securities surrendered for payment, redemption, transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities and Securities surrendered directly to the Trustee for any such purpose shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section 3.8 , except as expressly permitted by this Indenture. All canceled Securities shall be disposed of by the Trustee in accordance with its customary practices and the Trustee shall deliver to the Company a certificate of such disposition.

     SECTION 3.9. Deferrals of Interest Payment Dates.

     (a) So long as no Event of Default pursuant to Sections 5.1(c) , (e) , (f) , (g) or (h) has occurred and is continuing, the Company shall have the right, at any time and from time to time during the term of the Security, to defer the payment of interest on the Securities for a period of up to twenty (20) consecutive quarterly interest payment periods (each such period, an “ Extension Period ”), during which Extension Period(s), the Company shall have the right to make no payments or partial payments of interest on any Interest Payment Date (except any Additional Tax Sums that otherwise may be due and payable). No Extension Period shall end on a date other than an Interest Payment Date and no Extension Period shall extend beyond the Stated Maturity of the principal of the Securities. No interest shall be due and payable during an Extension Period, except at the end thereof, but each installment of interest that would otherwise have been due and payable during such Extension Period shall bear Additional Interest (to the extent payment of such interest would be legally enforceable) at a fixed rate per annum equal to 6.84% through the interest payment date in October, 2017, and a variable rate, per annum, reset quarterly, equal to LIBOR plus 1.58% thereafter, compounded quarterly, from the dates on which amounts would have otherwise been due and payable until paid or until funds for the payment thereof have been made available for payment. At the end of any such Extension Period, the Company shall pay all interest then accrued and unpaid on the Securities together with such Additional Interest. Prior to the termination of any such Extension Period, the Company may extend such Extension Period and further defer the payment of interest; provided , that (i) all such previous and further extensions comprising such Extension Period do not exceed

twenty (20) quarterly interest payment periods, (ii) no Extension Period shall end on a date other than an Interest Payment Date and (iii) no Extension Period shall extend beyond the Stated Maturity of the principal of the Securities. Upon the termination of any such Extension Period and upon the payment of all accrued and unpaid interest and any Additional Interest then due on any Interest Payment Date, the Company may elect to begin a new Extension Period; provided , that (i) such Extension Period does not exceed twenty (20) quarterly interest payment periods, (ii) no Extension Period shall end on a date other than an Interest Payment Date, (iii) no Extension Period shall extend beyond the Stated Maturity of the principal of the Securities and (iv) no Event of Default pursuant to Sections 5.1(c) , (e) , (f) , (g) or (h) has occurred and is continuing. The Company shall give (i) the Holders of the Securities, (ii) the Trustee, (iii) the Property Trustee and (iv) any beneficial owner of the Preferred Securities reasonably identified to the Company (which identification may be made either by such beneficial owner or by the Purchaser) written notice of its election to begin any such Extension Period no later than the close of business on the fifteenth (15th) Business Day prior to the next succeeding Interest Payment Date on which interest on the Securities would be payable but for such deferral.

     (b) In connection with any such Extension Period, the Company shall be subject to the restrictions set forth in Section 10.6(a) .

     SECTION 3.10. Right of Set-Off.

     Notwithstanding anything to the contrary herein, the Company shall have the right to set off any payment it is otherwise required to make in respect of any Security to the extent the Company has theretofore made, or is concurrently on the date of such payment making, a payment under the Guarantee Agreement relating to such Security or to a holder of Preferred Securities pursuant to an action undertaken under Section 5.8 of this Indenture.

     SECTION 3.11. Agreed Tax Treatment.

     Each Security issued hereunder shall provide that the Company and, by its acceptance or acquisition of a Security or a beneficial interest therein, the Holder of, and any Person that acquires a direct or indirect beneficial interest in, such Security, intend and agree to treat such Security as indebtedness of the Company for United States Federal, state and local tax purposes and to treat the Preferred Securities (including but not limited to all payments and proceeds with respect to the Preferred Securities) as an undivided beneficial ownership interest in the Trust (and payments and proceeds therefrom, respectively) for United States Federal, state and local tax purposes. The provisions of this Indenture shall be interpreted to further this intention and agreement of the parties.

     SECTION 3.12. CUSIP Numbers.

     The Company in issuing the Securities may use “CUSIP” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption and other similar or related materials as a convenience to Holders; provided , that any such notice or other materials may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of redemption or other materials and that

reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers.
