There is hereby authorized a series of Securities designated the “3.700% Fixed-to-Fixed Rate Subordinated Notes due 2030,” initially offered in the aggregate principal amount of $200,000,000, which amount shall be as set forth in a Company Order for the authentication and delivery of Notes pursuant to Section 3.3 of the Base Indenture.

-6-

Section 2.2 Maturity.

Unless earlier redeemed pursuant to Section 3.2 of this Supplemental Indenture, the date upon which the Notes shall become due and payable at final maturity, together with any accrued and unpaid interest, is the Maturity Date.

Section 2.3 Form, Payment and Appointment.

(a) Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the Company or one of its Subsidiaries, holds as of 11:00 a.m. New York City time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal, premium, if any, and interest then due.

(b) No service charge shall be made for any registration of transfer or exchange of the Notes, but the Company may require payment from the Holder of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

(c) The Paying Agent, Authenticating Agent and Security Registrar for the Notes shall initially be the Trustee.

(d) The Company initially appoints The Depository Trust Company (“DTC”) to act as Depository with respect to the Global Notes. The Trustee shall act as Custodian with respect to the Global Notes.

(e) The Notes shall be issuable in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof in book-entry form only.

Section 2.4 Global Notes.

The Notes shall be represented by a permanent global certificate (collectively, the “Global Notes”) deposited with, or on behalf of, DTC and registered in the name of Cede & Co. Unless and until certificated notes are issued under the limited circumstances described in the Indenture or this Section 2.4, no Holder shall be entitled to receive a definitive certificate representing the Notes. So long as DTC or any successor depositary or its nominee is the registered owner of the Global Note, DTC or any successor depositary, or such nominee, as the case may be, will be considered to be the sole owner or holder of the notes for all purposes of the Indenture. Beneficial interests in the Global Note will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may elect to hold interests in the Global Note through DTC either directly if they are participants in DTC or indirectly through organizations that are participants in DTC. In connection with any proposed transfer outside the book entry only system, there shall be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Internal Revenue Code Section 6045. The Trustee may rely on the information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

Section 2.5 Interest.

(a) Interest on the Notes will accrue (i) during the period from and including the Issue Date, to, but excluding, the Reset Date, or to, but excluding, the date of earlier redemption, at a fixed rate of 3.700% per annum and (ii) during the period from and including the Reset

-7-

Date, to, but excluding, the Maturity Date, or to, but excluding, the date of earlier redemption, at a rate per annum that will be the Five-year U.S. Treasury Rate as of the Reset Determination Date plus 3.437% per annum. Interest will be payable semiannually in cash in arrears on September 17 and March 17 of each year, commencing on March 17, 2021. Each such date on which interest is payable is an “Interest Payment Date.”

(b) Interest shall be computed on the basis of a 360-day year consisting of twelve 30-day months. If any scheduled Interest Payment Date falls on a day that is not a Business Day, the Company shall postpone the interest payment to the next succeeding Business Day, but the payment made on such date will be treated as having been made on the date that the payment was first due, and the Holders of the Notes will not be entitled to any further interest or other payments with respect to such postponement.

(c) The Company shall be responsible for making calculations called for under the Indenture and the Notes, including but not limited to determination of interest, Redemption Price, premium, if any, and any other amounts payable on the Notes. The Company shall make the calculations in good faith and, absent manifest error, its calculations will be final and binding on the Holders. The Company shall provide a schedule of its calculations to the Trustee when requested by the Trustee, and the Trustee is entitled to rely conclusively on the accuracy of the Company’s calculations without independent verification. The Trustee shall forward the Company’s calculations to any Holder upon the written request of such Holder. The Trustee, acting in any capacity hereunder, shall have no liability or responsibility for making any calculation called for under the Indenture or the Notes, and shall be entitled to rely conclusively upon the accuracy of the Company’s calculations without independent verification thereof.

(d) Unless the Company has delivered a notice of redemption for all outstanding Notes, with such redemption to occur on the Reset Date, the Company shall appoint a calculation agent with respect to the Notes prior to the Reset Determination Date, which calculation agent may be the Company or an Affiliate of the Company. The Five-year U.S. Treasury Rate will be determined by the calculation agent on the Reset Determination Date. Any determination, decision or election that may be made by the calculation agent hereunder, including any determination with respect to a rate, will be conclusive and binding absent manifest error, may be made in the calculation agent’s sole discretion, and, notwithstanding anything to the contrary herein, shall become effective without consent from any other party. The calculation agent’s determination of any interest rate will be on file at the Company’s principal offices, will be made available to any Holder upon request, and will be final and binding in the absence of manifest error.

ARTICLE 3

REDEMPTION AND REPURCHASE OF THE NOTES

Section 3.1 No Sinking Fund.

The Notes are not entitled to the benefit of any sinking fund. Article 12 of the Base Indenture shall not apply to the Notes.

-8-

Section 3.2 Optional Redemption and Regulatory Event Redemption.

(a) On at least 10 days but no more than 60 days prior written notice delivered to the Holders (which notice may be conditioned in our discretion on one or more conditions precedent, and the redemption date may be delayed until such time as any or all of such conditions have been satisfied or revoked by the Company if the Company determines that such conditions will not be satisfied; provided, however, that if any condition precedent has not been satisfied, the Company shall provide written notice to the Trustee no fewer than two Business Days prior to the Redemption Date stating that such condition has not been satisfied, the notice of redemption is rescinded or delayed and the redemption shall not occur or shall be delayed), the Company may redeem the Notes in whole or in part, commencing (i) on the Reset Date, but not prior thereto (except upon the occurrence of the events described in Section 3.2 (b)), and on any interest payment date thereafter, or (ii) at any time during the three-month period prior to the Maturity Date, in each case, at a redemption price equal to 100% of the principal amount of the Notes being redeemed, plus accrued and unpaid interest thereon, if any, to, but excluding, the Redemption Date. If fewer than all of the Notes are to be redeemed at any time, the Notes to be redeemed shall be selected in accordance with 11.3 of the Base Indenture.

(b) The Notes may not otherwise be redeemed prior to the Maturity Date, except that the Company may also, at its option, redeem the Notes, in whole, but not in part, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest to, but excluding, the Redemption Date, upon the occurrence of a Tax Event, Tier 2 Capital Event or a 1940 Act Event.

(c) Prior to giving any notice to the Holders pursuant to Section 3.2(b), the Company shall deliver to the Trustee an Opinion of Counsel and an Officers’ Certificate certifying that (i) a Tax Event, Tier 2 Capital Event or a 1940 Act Event has occurred and (ii) the Company is entitled to redeem the Notes in accordance with Section 3.2(b), and the Trustee may conclusively rely on such Opinion of Counsel and Officers’ Certificate.

(d) If the Company elects to have the Trustee deliver the notice of redemption on the Company’s behalf, then the Company shall have delivered to the Trustee no fewer than 15 days prior to the date such redemption notice is to be delivered (unless the Trustee agrees to a shorter period) an Officer’s Certificate providing such direction. Any partial redemption will be made in accordance with the DTC’s applicable procedures among all of the Holders. If any Note is to be redeemed in part only, the notice of redemption relating to such Note shall state the portion of the principal amount thereof to be redeemed. The Company shall calculate the redemption price as described in the terms of the Notes to be redeemed and will deliver an Officer’s Certificate to the Trustee setting forth the redemption price no later than two Business Days prior to the Redemption Date, and the Trustee will not be responsible for such calculation nor shall the Trustee have any duty to monitor the accuracy of any calculations made by the Company, which will be conclusive and binding on the Holders, absent manifest error. A replacement Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of the original Note. The Notes are not subject to redemption or prepayment at the option of the Holders.

(e) Under the Federal Reserve Board’s risk-based capital regulations in effect on the Issue Date, any redemption of the Notes will be subject to the prior approval of the Federal Reserve Board. In addition, prior to exercising the Company’s option to redeem any Notes, or immediately thereafter, the Company shall either replace the redeemed Notes with an equivalent amount of a financial instrument that meets the Federal Reserve Board’s

-9-

regulatory capital criteria, or demonstrate to the satisfaction of the Federal Reserve Board that following redemption, the Company would continue to hold an amount of capital that is commensurate with its risk.

(f) In addition to the Company’s right to redeem the Notes as set forth above in this Section 3.2, the Company may at any time and from time to time purchase Notes in open market transactions, tender offers or otherwise, subject to the prior approval of the Federal Reserve Board, to the extent such approval is then required.

Section 3.3 Effect of Redemption.

Unless the Company defaults in the payment of the Redemption Price, on and after the Redemption Date, (a) interest shall cease to accrue on the Notes immediately prior to the close of business on the Redemption Date, (b) the Notes shall become due and payable at the Redemption Price and (c) the Notes shall be void and all rights of the Holders in respect of the Notes shall terminate and lapse (other than the right to receive the Redemption Price upon surrender of such Notes but without interest on such Redemption Price). Following the notice of a redemption, neither the Company nor the Security Registrar shall be required to register the transfer of or exchange the Notes to be redeemed. The redemption provisions of Sections 11.5 and 11.6 of the Base Indenture shall not apply to the Notes.

Section 3.4 Redemption Procedures.

On or prior to 11:00 a.m. New York City time on any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 10.3 of the Base Indenture) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Notes that are to be redeemed on that date. If the Company gives an irrevocable notice of redemption with respect to the Notes pursuant to Section 3.2 of this Supplemental Indenture in connection with an optional redemption, and the Company has deposited with the Trustee or with the Paying Agent the Redemption Price of the Notes to be redeemed, then, on the Redemption Date, the Paying Agent shall irrevocably deposit such funds with the Depository. The Company shall also give the Depository irrevocable instructions and authority to pay the Redemption Price in immediately available funds to the Holders of beneficial interests in the Global Notes. If any Redemption Date is not a Business Day, then the Redemption Price shall be payable on the next Business Day (and without any interest or other payment in respect of any such delay). Interest to be paid on or before the Redemption Date for any Notes called for redemption shall be payable to the Holders on the Regular Record Date for the related Interest Payment Dates. If any Notes called for redemption are not so paid upon surrender thereof for redemption, the Redemption Price shall, until paid, bear interest from the Redemption Date at the Coupon Rate then in effect.

Section 3.5 No Other Redemption.

Except as set forth in this Article 3, the Notes shall not be redeemable by the Company prior to the Maturity Date.

making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company in furtherance of any such action.

The Base Indenture contains a number of other defaults but no other defaults under, or breaches of, the Base Indenture or the Notes will result in an Event of Default, whether after notice, the passage of time or otherwise.

Section 5.2 Acceleration of Maturity. This Section 5.2 shall replace Section 5.2 of the Base Indenture with respect to the Notes only.

In the case of an Event of Default specified in clause (2) of Section 5.1, the principal amount of all Notes and premium, if any, together with accrued and unpaid interest, if any, thereon, with respect thereto, shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. In the case of an Event of Default specified in clause (1) of Section 5.1, the Trustee or the Holders of at least 25% in aggregate principal amount of the Notes may declare the principal amount of all the Notes and premium, if any, together with accrued and unpaid interest, if any, thereon, to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal amount (or specified amount) and premium, if any, together with accrued and unpaid interest, if any, thereon, with respect thereto, shall become immediately due and payable.

At any time after such an acceleration has occurred with respect to the Notes and before a judgment or decree based on such acceleration has been obtained by the Trustee as provided below in this Article 5, the Holders of not less than a majority in principal amount of the Outstanding Notes, by written notice to the Company and the Trustee, may rescind and annul such acceleration and its consequences if:

(i) the Company has paid or deposited with the Trustee a sum sufficient to pay (A) all overdue interest on all Notes, (B) the principal of or premium (if any) on any Notes that have become due otherwise than by such acceleration and interest thereon at the rate or rates prescribed therefor in such Notes, (C) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate prescribed therefor in the Notes, and (D) all sums paid or advanced by the Trustee hereunder, the reasonable compensation, expenses, disbursements and advances due to Trustee under Section 6.7 of the Base Indenture, and all other amounts due under Section 6.7 of the Base Indenture;

(ii) all Events of Default with respect to the Notes, other than the nonpayment of the principal of the Notes that have become due solely by such acceleration, have been cured, waived or otherwise remedied as provided in Section 5.13 of the Base Indenture; and

(iii) the rescission would not conflict with any final judgment or decree of a court of competent jurisdiction.

No such rescission shall affect any subsequent default or impair any right consequent thereon.

-12-

Section 5.3 Default. This Section 5.3 shall replace Section 5.3 of the Base Indenture with respect to the Notes only.

In the case of a default (not constituting an Event of Default) in the payment of interest or principal, or premium, if any, which failure to pay continues for 30 days, the Company shall, upon the demand of the Trustee, pay to the Trustee, for the benefit of the Holders, the amount then due and payable on such Notes for principal, and premium, if any, and interest and, to the extent that payment of such interest is legally enforceable, interest on any overdue principal, and premium, if any, and on any overdue interest.

If a Default with respect to Notes (other than a Default constituting an Event of Default) occurs and is continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in the Indenture or the Notes or in aid of the exercise of any power granted therein, or to enforce any other proper remedy.

(a) In the event of a Bankruptcy Proceeding, then and in any such event the holders of Senior Indebtedness shall be entitled to receive payment in full of all amounts due on or to become due on or in respect of all Senior Indebtedness, before the Holders of the Notes are

-13-

entitled to receive any payment or distribution of any kind or character whether in cash, property or securities, on account of the Notes, and to that end holders of Senior Indebtedness shall be entitled to receive, for application to the payment thereof, any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, by set-off or otherwise, which may be payable or deliverable in respect of the Notes in any such Bankruptcy Proceeding.

Section 6.4 No Payment When Senior Indebtedness in Default.

The Company shall not make any payment on account of the Notes unless full payment of amounts then due for principal (and premium, if any), sinking funds, and interest on Senior Indebtedness has been made or duly provided for in money or Government Obligations in accordance with its terms. No payment on account of the Notes shall be made by the Company if, at the time of such payment or immediately after giving effect thereto, there shall have occurred an event of default with respect to any Senior Indebtedness or in

-14-

any instrument under which the same is outstanding, permitting the holders thereof (or a trustee on behalf of the holders thereof) to accelerate the maturity thereof, or an event that, with the giving of notice or the passage of time or both, would constitute such event of default, and such event of default shall not have been cured or waived.

Section 6.5 Payment Permitted If No Default.

Nothing contained in Article 6 or elsewhere in this Indenture, or in any of the Notes or any series, shall prevent (a) the Company, at any time except during any Bankruptcy Proceeding, or under the conditions described in Section 6.3 or 6.4, from making payments at any time of principal of (or premium, if any) or interest on the Notes or (b) the application by the Trustee or any Paying Agent of any moneys deposited with it hereunder to the payment of (or premium, if any) or on account of the principal of or interest on the Notes, if, at the time of such application, the Trustee or such Paying Agent, as the case may be, did not have the written notice described in Section 6.10 or 6.14, as applicable, of any event prohibiting the making of such deposit or if, at the time of such deposit (whether or not in trust) by the Company with the Trustee or any Paying Agent (other than the Company), such payment would not have been prohibited by the provisions of this Section.

Section 6.6 Subrogation to Rights of Holders of Senior Indebtedness.

Subject to the payment in full of all Senior Indebtedness, the Holders of the Notes shall be subrogated (equally and ratably with the Holders of all Indebtedness of the Company that by its express terms is subordinated in right of payment to Senior Indebtedness to substantially the same extent as the Notes are subordinated and is entitled to like rights of subrogation) to the rights of the holders of such Senior Indebtedness to receive payments and distributions of cash, property and securities applicable to the Senior Indebtedness until the principal of, premium (if any) and interest on the Notes shall be paid in full. For purposes of such subrogation, no payments or distributions to the Holders of the Senior Indebtedness of any cash, property or securities to which the Holders of the Notes or the Trustee would be entitled except for the provisions of this Article 6, and no payments over pursuant to the provisions of this Article 6 to the holders of Senior Indebtedness by Holders of the Notes or the Trustee, shall, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Notes, be deemed to be a payment or distribution by the Company to or on account of the Senior Indebtedness.

Section 6.7 Provisions Solely to Define Relative Rights.

The provisions of this Article 6 are and are intended solely for the purpose of defining the relative rights of the Holders of the Notes, on the one hand, and the holders of Senior Indebtedness, on the other hand. Nothing contained in this Section 6 or elsewhere in this Indenture or in the Notes is intended to or shall (a) impair, as among the Company, its creditors other than holders of Senior Indebtedness and the Holders of the Notes, the obligation of the Company, which is absolute and unconditional (and which, subject to the rights under this Article 6 of the holders of Senior Indebtedness, is intended to rank equally in right of payment with all other general obligations of the Company), to pay to the Holders of the Notes the principal of, premium (if any) and interest on the Notes as and when the same shall become due and payable in accordance with their terms; or (b) affect the relative rights against the Company of the Holders of the Notes and creditors of the Company other than the holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Notes from exercising all remedies otherwise permitted by applicable law upon default under the

-15-

Indenture, subject to the rights, if any, under this Article 6 of the holders of Senior Indebtedness to receive cash, property and securities otherwise payable or deliverable to the Trustee or such Holder.

Section 6.8 Trustee to Effectuate Subordination.

Each Holder of the Notes by its acceptance thereof authorizes and directs the Trustee on its behalf to take such action as it directs to effectuate the subordination provided in this Article 6 and appoints the Trustee its attorney-in-fact for any and all such purposes, including, in the event of any dissolution, winding up, liquidation or reorganization of the Company whether in bankruptcy, insolvency, receivership proceedings, or otherwise, the timely filing of a claim for the unpaid balance of the Indebtedness of the Company owing to such Holder in the form required in such proceedings and the causing of such claim to be approved.

If the Trustee does not file a proper claim to effectuate the subordination provided in this Article 6 or proof of debt at least 30 days before the expiration of the time to file such claim, then any holders of the Senior Indebtedness and their agents, trustees or other representatives are authorized to do so (but shall in no event be liable for any failure to do so) for and on behalf of the Holders of the Notes.

Section 6.9 No Waiver of Subordination Provisions; Modifications of Terms of Senior Indebtedness.

No right of any present or future holder of any Senior Indebtedness to enforce subordination as provided in this Article 6 shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company or by any act or failure to act, in good faith, by any such holder, or by any noncompliance by the Company with the terms, provisions and covenants of the Indenture, regardless of any knowledge thereof that any such holder may have or be otherwise charged with.

Section 6.10 Notice to Trustee.

(a) The Company shall give prompt written notice to the Trustee of any fact known to the Company that would prohibit the making of any payment to or by the Trustee in respect of the Notes or that would end such prohibition. Notwithstanding the provisions of this Article 6 or any other provision of this Indenture, the Trustee shall not be charged with knowledge of the existence of any facts that would prohibit the making of any payment to or by the Trustee in respect of the Notes or that would end such prohibition, unless and until a Responsible Officer of the Trustee shall have received written notice thereof from the Company, from any holder of Senior Indebtedness or from any trustee, fiduciary or agent therefor; and, prior to the receipt of any such written notice, the Trustee, subject to the provisions of Section 6.1 of the Base Indenture, shall be entitled in all respects to assume that no such facts exist; provided, however, that if the Trustee shall not have received the notice of any prohibition provided for in this Section 6.10 at least three Business Days prior to the date upon which by the terms of this Supplemental Indenture any money may become payable for any purpose (including, without limitation, the payment of the principal of, premium (if any) or interest on the Notes), then, anything herein contained to the contrary notwithstanding, but without limiting the rights and remedies of the holders of Senior Indebtedness or any trustee, fiduciary or agent therefor, the Trustee shall have full power and authority to receive such money and to apply the same to the purpose for which such money

-16-

was received and shall not be affected by any notice to the contrary which may be received by it within two Business Days prior to such date. Any notice required or permitted to be given to the Trustee by a holder of Senior Indebtedness or by any agent, trustee or representative thereof shall be in writing and shall be sufficient for every purpose hereunder if in writing and either (i) sent via facsimile to the Trustee, the receipt of which shall be confirmed via telephone, or (ii) personally delivered, or mailed, first class postage prepaid, or sent by overnight carrier, to the Trustee addressed to its Corporate Trust Office or to any other address furnished in writing to such holder of Senior Indebtedness by the Trustee.

(2) Subject to the provisions of Section 6.1 of the Base Indenture, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing that such Person is a holder of Senior Indebtedness (or a trustee, fiduciary or agent therefor) to establish that such notice has been given by a holder of Senior Indebtedness or a trustee, fiduciary or agent therefor. If the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Article 6, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and any other facts pertinent to the rights of such Person under this Article 6, and if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment.

(3) Notwithstanding anything else contained herein, no notice, request or other communication to or with the Trustee shall be deemed given unless received by a Responsible Officer at its Corporate Trust Office.

Section 6.11 Reliance on Judicial Order or Certificate of Liquidating Agent.

Upon any payment or distribution of assets of the Company referred to in this Article 6, the Trustee, subject to the provisions of Section 6.1 of the Base Indenture, and the Holders of the Notes shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such Bankruptcy Proceeding is pending, or a certificate of any receiver, trustee, assignee, liquidator or other similar official under any Bankruptcy Law, or any agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Notes, for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other Indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article 6, provided that the foregoing shall apply only if such court has been apprised of the provisions of this Article 6.

Section 6.12 Trustee Not Fiduciary for Holders of Senior Indebtedness.

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness (or any Person) and shall not be liable to any such holders if it shall in good faith mistakenly pay over or distribute to Holders of Notes or to the Company or to any other Person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article 6 or otherwise. With respect to the holders of Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants or obligations as are specifically set forth in this Article 6 and no implied covenants or obligations with respect to holders of Senior Indebtedness shall be read into this Indenture against the Trustee.

-17-

Section 6.13 Rights of Trustee as Holder of Senior Indebtedness; Preservation of Trustee’s Rights.

(1) The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article 6 with respect to any Senior Indebtedness that may at any time be held by it, to the same extent as any other holder of Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.

(2) Nothing in this Article 6 shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.7 of the Base Indenture.

Section 6.14 Article Applicable to Paying Agents.

In case at any time any Paying Agent other than the Trustee shall be then acting hereunder, the term “Trustee” as used in this Article 6 shall in such case (unless the context otherwise requires) be construed as extending to and including such Paying Agent within its meaning as fully for all intents and purposes as if such Paying Agent were named in this Section in addition to or in place of the Trustee; provided, however, that Section 6.12 of this Supplemental Indenture shall not apply to the Company or any Affiliate of the Company if it or such Affiliate acts as Paying Agent.

Section 6.15 Redemption.
