 WHEREAS, the Old Capital Securities were issued by the Issuer Trust and the proceeds thereof, together with the proceeds from the issuance

 (a) This Guarantee Agreement shall be held by the Guarantee Trustee for the
benefit of the Holders, and the Guarantee Trustee shall not transfer this Guarantee Agreement to any Person except to a Successor Guarantee Trustee on acceptance by such Successor Guarantee Trustee of its appointment to act as Guarantee Trustee
hereunder. The right, title and interest of the Guarantee Trustee, as such, hereunder shall automatically vest in any Successor Guarantee Trustee, upon acceptance by such Successor Guarantee Trustee of its appointment hereunder, and such vesting and

 (b) If an Event of Default has occurred and is continuing, the Guarantee Trustee shall enforce this Guarantee Agreement for
the benefit of the Holders. 
  
 (c) The Guarantee Trustee, before
the occurrence of any Event of Default and after the curing of all Events of Default that may have occurred, shall undertake to perform only such duties as are specifically set forth in this Guarantee Agreement (including pursuant to Section 2.1),
and no implied covenants shall be read into this Guarantee Agreement against the Guarantee Trustee. If an Event of Default has occurred (that has not been cured or waived pursuant to Section 2.6), the Guarantee Trustee shall exercise such of the
rights and powers vested in it by this Guarantee Agreement, and use the same degree of care and skill in its exercise thereof, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. 
  
 (d) No provision of this Guarantee Agreement shall be construed to relieve
the Guarantee Trustee from liability for its own negligent action, its own negligent failure to act or its own wilful misconduct, except that: 
  
 (i) Prior to the occurrence of any Event of Default and after the curing or waiving of all such Events of Default that may have occurred:

  
 (A) the duties and obligations of the
Guarantee Trustee shall be determined solely by the express provisions of this Guarantee Agreement (including pursuant to Section 2.1), and the Guarantee Trustee shall not be liable except for the performance of such duties and obligations as are

  

 -7- 

 
specifically set forth in this Guarantee Agreement (including pursuant to Section 2.1); and 
  
 (B) in the absence of bad faith on the part of the Guarantee Trustee, the Guarantee Trustee may conclusively
rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Guarantee Trustee and conforming to the requirements of this Guarantee Agreement; but in the case of
any such certificates or opinions that by any provision hereof or of the Trust Indenture Act are specifically required to be furnished to the Guarantee Trustee, the Guarantee Trustee shall be under a duty to examine the same to determine whether or
not they conform to the requirements of this Guarantee Agreement. 
  
 (ii) The Guarantee Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Guarantee Trustee was negligent in ascertaining the pertinent
facts upon which such judgment was made. 
  
 (iii) The Guarantee Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with the direction of the Holders of not less than a Majority in Liquidation Amount of the Capital
Securities relating to the time, method and place of conducting any proceeding for any remedy available to the Guarantee Trustee, or exercising any trust or power conferred upon the Guarantee Trustee under this Guarantee Agreement. 
  
 (iv) Subject to Section 3.1(b), no provision of this
Guarantee Agreement shall require the Guarantee Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or powers, if the Guarantee
Trustee shall have reasonable grounds for believing that the repayment of such funds or liability is not reasonably assured to it under the terms of this Guarantee Agreement or adequate indemnity against such risk or liability is not reasonably
assured to it. 
  
 Section 3.2. Certain Rights of Guarantee
Trustee. 
  
 (a) Subject to the provisions of Section 3.1:

  
 (i) The Guarantee Trustee may conclusively
rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or
other paper or document reasonably believed by it to be genuine and to have been signed, sent or presented by the proper party or parties. 
  

 -8- 

 (ii) Any direction or act of the Guarantor contemplated by this Guarantee Agreement shall
be sufficiently evidenced by an Officers’ Certificate unless otherwise prescribed herein. 
  
 (iii) Whenever, in the administration of this Guarantee Agreement, the Guarantee Trustee shall deem it desirable that a matter be proved
or established before taking, suffering or omitting to take any action hereunder, the Guarantee Trustee (unless other evidence is herein specifically prescribed) may, in the absence of bad faith on its part, request and rely upon an Officers’
Certificate which, upon receipt of such request from the Guarantee Trustee, shall be promptly delivered by the Guarantor. 
  
 (iv) The Guarantee Trustee may consult with legal counsel, and the advice or opinion of such legal counsel with respect to legal matters
shall be full and complete authorization and protection in respect of any action taken, suffered or omitted to be taken by it hereunder in good faith and in accordance with such advice or opinion. Such legal counsel may be legal counsel to the
Guarantor or any of its Affiliates and may be one of its employees. The Guarantee Trustee shall have the right at any time to seek instructions concerning the administration of this Guarantee Agreement from any court of competent jurisdiction.

  
 (v) The Guarantee Trustee shall be under no
obligation to exercise any of the rights or powers vested in it by this Guarantee Agreement at the request or direction of any Holder unless such Holder shall have provided to the Guarantee Trustee such adequate security and indemnity reasonably
satisfactory to the Guarantee Trustee against the costs, expenses (including attorneys’ fees and expenses) and liabilities that might be incurred by it in complying with such request or direction, including such reasonable advances as may be
requested by the Guarantee Trustee; provided that nothing contained in this Section 3.2(a)(v) shall be taken to relieve the Guarantee Trustee, upon the occurrence of an Event of Default, of its obligation to exercise the rights and powers
vested in it by this Guarantee Agreement. 
  
 (vi) The Guarantee Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture,
note, other evidence of indebtedness or other paper or document, but the Guarantee Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit. 
  
 (vii) The Guarantee Trustee may execute any of the trusts or
powers hereunder or perform any duties hereunder either directly or by or through its agents or attorneys, and the Guarantee Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed by it
with due care hereunder. 
  

 -9- 

 (viii) Whenever in the administration of this Guarantee Agreement the Guarantee Trustee
shall deem it desirable to receive instructions with respect to enforcing any remedy or right or taking any other action hereunder, the Guarantee Trustee (A) may request instructions from the Holders, (B) may refrain from enforcing such remedy or
right or taking such other action until such instructions are received, and (C) shall be protected in acting in accordance with such instructions. 
  
 (ix) The Guarantee Trustee shall not be liable for any action taken, suffered, or omitted to be taken by it in good faith and reasonably
believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Guarantee Agreement. 
  
 (b) No provision of this Guarantee Agreement shall be deemed to impose any duty or obligation on the Guarantee Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any jurisdiction in which it shall be illegal, or in which the Guarantee Trustee shall be unqualified or incompetent in accordance with applicable law, to perform any such
act or acts or to exercise any such right, power, duty or obligation. No permissive power or authority available to the Guarantee Trustee shall be construed to be a duty to act in accordance with such power and authority.

 GUARANTEE TRUSTEE 
  
 Section 4.1. Guarantee Trustee; Eligibility. 
  
 (a) There shall at all times be a Guarantee Trustee which shall: 
  

(i) not be an Affiliate of the Guarantor; and 
  

(ii) be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus of at least
$50,000,000, and shall be a corporation meeting the requirements of Section 310(a) of the Trust Indenture Act. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of its supervising or
examining authority, then, for the purposes of this Section 4.1 and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its
most recent report of condition so published. 
  
 (b) If at any
time the Guarantee Trustee shall cease to be eligible to so act under Section 4.1(a), the Guarantee Trustee shall immediately resign in the manner and with the effect set out in Section 4.2. 
  
 (c) If the Guarantee Trustee has or shall acquire any “conflicting
interest” within the meaning of Section 310(b) of the Trust Indenture Act, the Guarantee Trustee and Guarantor shall in all respects comply with the provisions of Section 310(b) of the Trust Indenture Act. 
  
 Section 4.2. Appointment, Removal and Resignation of the Guarantee
Trustee. 
  
 (a) Subject to Section 4.2(c), unless a Debenture
Event of Default (as defined in the Trust Agreement) shall have occurred and be continuing, the Guarantee Trustee may be appointed or removed at any time by the Guarantor. If a Debenture Event of Default (as defined in the Trust Agreement) shall
have occurred and be continuing, the Guarantee Trustee may be appointed or removed at any time by the action of the Holders of a Majority in Liquidation Amount of the Capital Securities delivered to the Guarantee Trustee. 
  
 (b) Subject to Section 4.2(c), the Guarantee Trustee may resign from office
(without need for prior or subsequent accounting) by giving written notice thereof to the Holders and the Guarantor. 
  
 (c) The Guarantee Trustee appointed hereunder shall hold office until a Successor Guarantee Trustee shall have been appointed and shall have accepted such
appointment. No removal or resignation of a Guarantee Trustee shall be effective until a Successor Guarantee Trustee has been appointed and has accepted such appointment by written instrument executed by such Successor Guarantee Trustee and
delivered to the Guarantor and, in the case of any resignation, the resigning Guarantee Trustee. 
  

 -11- 

 (d) If no Successor Guarantee Trustee shall have been appointed and accepted appointment as provided in
this Section 4.2 within 60 days after delivery to the Holders and the Guarantor of a notice of resignation, the resigning Guarantee Trustee may petition, at the expense of the Guarantor, any court of competent jurisdiction for appointment of a
Successor Guarantee Trustee. Such court may thereupon, after prescribing such notice, if any, as it may deem proper, appoint a Successor Guarantee Trustee. 
  
 (e) If a Guarantee Trustee shall be removed or become incapable of acting as Guarantee Trustee and a replacement shall not be appointed prior to such
resignation or removal, or if a vacancy shall occur in the office of Guarantee Trustee for any cause, the Holders of the Capital Securities, by the action of the Holders of record of not less than 25% in aggregate Liquidation Amount (as defined in
the Trust Agreement) of the Capital Securities then Outstanding (as defined in the Trust Agreement) delivered to such Guarantee Trustee, may appoint a Successor Guarantee Trustee or Trustees. If no Successor Guarantee Trustee shall have been so
appointed by the Holders of the Capital Securities and accepted appointment, any Holder, on behalf of such Holder and all others similarly situated, or any other Guarantee Trustee, may petition any court of competent jurisdiction for the appointment
of a Successor Guarantee Trustee. 
  
 ARTICLE V 
  
 GUARANTEE 
  
 Section 5.1. Guarantee. 
  
 The Guarantor irrevocably and unconditionally agrees to pay in full to the
Holders the Guarantee Payments (without duplication of amounts theretofore paid by or on behalf of the Issuer Trust), as and when due, regardless of any defense, right of set-off or counterclaim that the Issuer Trust may have or assert, except the
defense of payment. The Guarantor’s obligation to make a Guarantee Payment may be satisfied by direct payment of the required amounts by the Guarantor to the Holders or by causing the Issuer Trust to pay such amounts to the Holders. 

 
 Section 5.2. Waiver of Notice and Demand. 
  
 The Guarantor hereby waives notice of acceptance of this Guarantee Agreement
and of any liability to which it applies or may apply, presentment, demand for payment, any right to require a proceeding first against the Guarantee Trustee, the Issuer Trust or any other Person before proceeding against the Guarantor, protest,
notice of nonpayment, notice of dishonor, notice of redemption and all other notices and demands. 
  
 Section 5.3. Obligations Not Affected. 
  
 The obligations, covenants, agreements and duties of the Guarantor under this Guarantee Agreement shall in no way be affected or impaired by reason of the
happening from time to time of any of the following: 
  
 (a) the
release or waiver, by operation of law or otherwise, of the performance or observance by the Issuer Trust of any express or implied agreement, covenant, term or condition relating to the Capital Securities to be performed or observed by the Issuer
Trust; 
  

 -12- 

 (b) the extension of time for the payment by the Issuer Trust of all or any portion of the Distributions
(other than an extension of time for payment of Distributions that results from the extension of any interest payment period on the Debentures as provided in the Indenture), Redemption Price, Liquidation Distribution or any other sums payable under
the terms of the Capital Securities or the extension of time for the performance of any other obligation under, arising out of, or in connection with, the Capital Securities; 
  
 (c) any failure, omission, delay or lack of diligence on the part of the Holders to enforce, assert or exercise any right,
privilege, power or remedy conferred on the Holders pursuant to the terms of the Capital Securities, or any action on the part of the Issuer Trust granting indulgence or extension of any kind; 
  
 (d) the voluntary or involuntary liquidation, dissolution, receivership,
insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of debt of, or other similar proceedings affecting, the Issuer Trust or any of the assets of the Issuer Trust; 
  
 (e) any invalidity of, or defect or deficiency in, the Capital Securities;

  
 (f) the settlement or compromise of any obligation guaranteed
hereby or hereby incurred; or 
  
 (g) any other circumstance
whatsoever that might otherwise constitute a legal or equitable discharge or defense of a guarantor (other than payment of the underlying obligation), it being the intent of this Section 5.3 that the obligations of the Guarantor hereunder shall be
absolute and unconditional under any and all circumstances. 
  
 There shall be no obligation of the Holders to give notice to, or obtain the consent of, the Guarantor with respect to the happening of any of the foregoing. 
  
 Section 5.4. Rights of Holders. 
  
 The Guarantor expressly acknowledges that: (a) this Guarantee Agreement will be deposited with the Guarantee Trustee to be
held for the benefit of the Holders; (b) the Guarantee Trustee has the right to enforce this Guarantee Agreement on behalf of the Holders; (c) the Holders of a Majority in Liquidation Amount of the Capital Securities have the right to direct the
time, method and place of conducting any proceeding for any remedy available to the Guarantee Trustee in respect of this Guarantee Agreement or exercising any trust or power conferred upon the Guarantee Trustee under this Guarantee Agreement; and
(d) any Holder may institute a legal proceeding directly against the Guarantor to enforce its rights under this Guarantee Agreement without first instituting a legal proceeding against the Guarantee Trustee, the Issuer Trust or any other Person.

  

 -13- 

 Section 5.5. Guarantee of Payment. 
  
 This Guarantee Agreement creates a guarantee of payment and not of collection. This Guarantee Agreement will not be
discharged except by payment of the Guarantee Payments in full (without duplication of amounts theretofore paid by the Issuer Trust) or upon the distribution of Debentures to Holders as provided in the Trust Agreement. 
  
 Section 5.6. Subrogation. 
  
 The Guarantor shall be subrogated to all rights (if any) of the Holders
against the Issuer Trust in respect of any amounts paid to the Holders by the Guarantor under this Guarantee Agreement; provided, however, that the Guarantor shall not (except to the extent required by mandatory provisions of law) be entitled
to enforce or exercise any rights which it may acquire by way of subrogation or any indemnity, reimbursement or other agreement, in all cases as a result of payment under this Guarantee Agreement, if, at the time of any such payment, any amounts are
due and unpaid under this Guarantee Agreement. If any amount shall be paid to the Guarantor in violation of the preceding sentence, the Guarantor agrees to hold such amount in trust for the Holders and to pay over such amount to the Holders.

  
 Section 5.7. Independent Obligations. 
  
 The Guarantor acknowledges that its obligations hereunder are independent of
the obligations of the Issuer Trust with respect to the Capital Securities and that the Guarantor shall be liable as principal and as debtor hereunder to make Guarantee Payments pursuant to the terms of this Guarantee Agreement notwithstanding the
occurrence of any event referred to in subsections (a) through (g), inclusive, of Section 5.3 hereof. 
  
 ARTICLE VI 
  
 COVENANTS AND SUBORDINATION 
  
 Section 6.1. Subordination.

Guarantor to the extent and in the manner set forth in the Indenture with respect to the Debentures, and the provisions of Article XIII of the Indenture will apply, mutatis mutandis, to the obligations of the Guarantor hereunder. The
obligations of the Guarantor hereunder do not constitute Senior Indebtedness (as defined in the Indenture) of the Guarantor.

Issuer Trust (as defined in the Indenture), and (d) any other security, guarantee or other agreement or obligation that is expressly stated to rank pari passu with the obligations of the Guarantor under this Guarantee Agreement or with any
obligation that ranks pari passu with the obligations of the Guarantor under this Guarantee Agreement. 
  
 ARTICLE VII

full payment of the amounts payable in accordance with Article IX of the Trust Agreement upon liquidation of the Issuer Trust. Notwithstanding the foregoing, this Guarantee Agreement will continue to be effective or will be reinstated, as the case
may be, if at any time any Holder is required to repay any sums paid with respect to Capital Securities or this Guarantee Agreement. 
  
 ARTICLE VIII 
  
 MISCELLANEOUS 
  
 Section 8.1. Successors and Assigns.

Capital Securities then outstanding. Except in connection with a consolidation, merger or sale involving the Guarantor that is permitted under Article VIII of the Indenture and pursuant to which the successor or assignee agrees in writing to perform
the Guarantor’s obligations hereunder, the Guarantor shall not assign its obligations hereunder, and any purported assignment other than in accordance with this provision shall be void. 
  
 Section 8.2. Amendments. 
  
 Except with respect to any changes that do not adversely affect the rights of
the Holders in any material respect (in which case no consent of the Holders will be required), this Guarantee Agreement may only be amended with the prior approval of the Holders of not less than a Majority in Liquidation Amount of the Capital

 Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions, or other instruments under this Indenture, they may, but need not, be
consolidated and form one instrument. 
  
 Section 1.4. Acts of
Holders. 
  
 (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to be given to or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an
agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments is or are delivered to the Trustee, and, where it is hereby expressly required, to the
Corporation. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such
instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 6.1) conclusive in favor of the Trustee and the Corporation, if made in the manner provided in this Section.

  
 (b) The fact and date of the execution by any Person of any
such instrument or writing may be proved by the affidavit of a witness of such execution or by the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such
instrument or writing acknowledged to him or her the execution thereof. Where such execution is by a Person acting in other than his or her 

  

 -11- 

 
individual capacity, such certificate or affidavit shall also constitute sufficient proof of his or her authority. 
  
 (c) The fact and date of the execution by any Person of any such instrument
or writing, or the authority of the Person executing the same, may also be proved in any other manner that the Trustee deems sufficient and in accordance with such reasonable rules as the Trustee may determine. 
  
 (d) The ownership of Securities shall be proved by the Securities Register.

  
 (e) Any request, demand, authorization, direction, notice,
consent, waiver or other action by the Holder of any Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the transfer thereof or in exchange therefor or in lieu thereof in respect of anything
done or suffered to be done by the Trustee or the Corporation in reliance thereon, whether or not notation of such action is made upon such Security. 
  
 (f) The Corporation may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give,
make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of such series, provided that the Corporation may
not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next succeeding paragraph. If any record date is set pursuant
to this paragraph, the Holders of Outstanding Securities of the relevant series 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 of such series on such record date.
Nothing in this paragraph shall be construed to prevent the Corporation 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 cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Corporation, 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 of the relevant series in the manner set forth in Section 1.6. 
  
 The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the
giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 5.2, (iii) any request to institute proceedings referred to in Section 5.7(2), or (iv) any direction referred to in Section 5.12, in each case
with respect to Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration,

  

 -12- 

 
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 of such series 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 cancelled and of no effect), and nothing in
this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant
to this paragraph, the Trustee, at the Corporation’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Corporation in writing and to each Holder of Securities
of the relevant series in the manner set forth in Section 1.6. 
  
 With respect to any record date set pursuant to this Section, 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 of the relevant series 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, the party hereto that set such record date shall be deemed to have initially designated
the 180th 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 180th day
after the applicable record date. 
  
 (g) Without limiting the
foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do
so pursuant to such appointment with regard to all or any part of such principal amount. 
  
 Section 1.5. Notices, Etc. to Trustee and Corporation. 
  
 Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, 
  
 (1) the Trustee by any Holder, any holder of Capital
Securities or the Corporation shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing to or with the Trustee at its Corporate Trust Office, or 
  
 (2) the Corporation by the Trustee, any Holder or any holder of Capital Securities shall be sufficient for
every purpose (except as otherwise provided in Section 5.1) hereunder if in writing and mailed, first class, postage prepaid, to the Corporation addressed to it at the address of its principal office specified in the first

paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Corporation. 
  
 Section 1.6. Notice to Holders; Waiver. 
  
 Where this Indenture provides for notice to Holders of any event, such notice
shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first class postage prepaid, to each Holder affected by such event, at the address of such Holder as it appears in the Securities Register, not later
than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. 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 or of the relevant Securities, 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. 
  
 Section 1.7. Conflict with Trust Indenture Act. 
  
 Except as otherwise expressly provided herein, the Trust Indenture Act shall apply as a matter of contract to this Indenture
for purposes of interpretation, construction and defining the rights and obligations hereunder, and this Indenture, the Corporation, and the Trustee shall be deemed for all purposes hereof to be subject to and governed by the Trust Indenture Act to
the same extent as would be the case if this Indenture were qualified under that Act on the date hereof. Except as otherwise provided herein, if and to the extent that any provision of this Indenture limits, qualifies or conflicts with the duties
imposed by any of Sections 310 to 317, inclusive, of the Trust Indenture Act through operation of Section 318(c) thereof, such imposed duties shall control. 
  
 Section 1.8. Effect of Headings and Table of Contents. 
  
 The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof. 
  
 Section 1.9. Successors and Assigns. 
  
 All covenants and agreements in this Indenture by the Corporation shall bind
its successors and assigns, whether so expressed or not. 
  

 -14- 

 Section 1.10. Separability Clause. 
  
 If any provision in this Indenture or in the Securities shall be invalid, illegal or unenforceable, the validity, legality
and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. 
  
 Section 1.11. Benefits of Indenture. 
  
 Nothing in this Indenture or in the Securities, express or implied, shall give to any Person, other than the parties hereto and their successors and
assigns, the holders of Senior Indebtedness, the Holders of the Securities and, to the extent expressly provided in Sections 5.1, 5.2, 5.8, 5.9, 5.11, 5.13, 9.1 and 9.2, the holders of Capital Securities, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

Governing Law. 
  
 This Indenture and the Securities shall
be governed by, and construed in accordance with, the laws of the State of New York. 
  
 Section 1.13. Non-Business Days. 
  
 If any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day, then (notwithstanding any other provision of this Indenture or the Securities (other than a provision of any Security which
specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) or other amounts in respect of such Security need not be made on such date, but may be made on the next succeeding
Business Day (and no interest shall accrue in respect of the amounts whose payment is so delayed for the period from and after such Interest Payment Date, Redemption Date or Stated Maturity, as the case may be, until such next succeeding Business
Day) except that, if such Business Day falls in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day (in each case with the same force and effect as if made on the Interest Payment Date or
Redemption Date or at the Stated Maturity). 
  
 Section 1.14.
Execution in Counterparts. 
  
 This Indenture may be
executed and delivered in any number of counterparts, each of which when so executed and delivered shall be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

the debt securities of any subsidiary of the Corporation if such guarantee ranks pari passu in all respects with or junior in interest to Securities issued to an Issuer Trust or (iii) declare or pay any dividends or distributions on, or
redeem, purchase, acquire or make a liquidation payment with respect to, any of the Corporation’s capital stock (other than (a) repurchases, redemptions or other acquisitions of shares of capital stock of the Corporation in connection with any

first paragraph of this Security, from the dates on which amounts would otherwise have been due and payable until paid or made available for payment. The Corporation shall give the Holder of this Security and the Trustee notice of its election to

held by [insert name of applicable Issuer Trust], at least five Business Days prior to the earlier of (i) the next succeeding date on which Distributions on the Capital Securities of such Issuer Trust would be payable but for such deferral,

 Payment of the principal of (and premium, if any) and interest payable at
Maturity on this Security will be made at the office or agency of the Corporation maintained for that purpose in the [insert Place of Payment], in such coin or currency of the United States of America as at the time of payment is legal tender

address of the Person entitled thereto as such address shall appear in the Securities Register, or (ii) by wire transfer in immediately available funds at such place and to such account as may be designated by the Person entitled thereto as
specified in the Securities Register].

evidenced by this Security is, to the extent provided in the Indenture, subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness, and this Security is issued subject to the provisions of the Indenture with
respect thereto. Each Holder of this Security, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his or her behalf to take such actions as may be necessary or appropriate to
effectuate the subordination so provided, and (c) appoints the Trustee his or her attorney-in-fact for any and all such purposes. Each Holder hereof, by his or her acceptance hereof, waives all notice of the acceptance of the subordination
provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions. 
  
 Reference is hereby made to the further provisions of this Security set forth
on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

indentures for the purpose of modifying in any manner the rights and obligations of the Corporation and of the Holders of the Securities, with the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities
of each series to be affected by such supplemental indenture. The Indenture also contains provisions permitting Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders

 Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the
Corporation shall bind the Corporation, notwithstanding that 

  

 -28- 

 
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. At any time and from time to time after the execution and delivery of this Indenture, the Corporation may deliver Securities of any series executed by the Corporation to the Trustee for authentication, together with a
Corporation Order for the authentication and delivery of such Securities, and the Trustee in accordance with the Corporation Order shall authenticate and make available for delivery such Securities. If the form or terms of the Securities of the
series have been established by or pursuant to one or more Board Resolutions as permitted by Sections 2.1 and 3.1, 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 (subject to Section 6.1) shall be fully protected in relying upon, an Opinion of Counsel stating, 
  
 (1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 2.1, that such form has
been established in conformity with the provisions of this Indenture; 
  
 (2) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by Section 3.1, that such terms have been established in conformity with the provisions of this Indenture; and

  
 (3) that such Securities, when authenticated
and made available for delivery by the Trustee and issued by the Corporation in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Corporation, 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. 
  
 If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner that is not
reasonably acceptable to the Trustee. 
  
 Notwithstanding the
provisions of Section 3.1 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.1 or
the Corporation Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original
issuance of the first Security of such series to be issued. 
  
 Each Security shall be dated the date of its authentication. 
  
 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 

  

 -29- 

 
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 Corporation, and the Corporation shall deliver such Security to the Trustee for cancellation as provided in Section 3.10, 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. 
  

Section 3.4. Temporary Securities. 
  
 Pending the preparation of definitive Securities of any series, the Corporation may execute, and upon Corporation Order the Trustee shall authenticate and
make available for delivery, temporary Securities that are printed, lithographed, typewritten, mimeographed or otherwise produced, in any denomination, substantially of the tenor of the definitive Securities of such series in lieu of which they are
issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities. 
  
 If temporary Securities of any series are issued, the Corporation will cause
definitive Securities of such series to be prepared without unreasonable delay. After the preparation of definitive Securities, the temporary Securities shall be exchangeable for definitive Securities upon surrender of the temporary Securities at
the office or agency of the Corporation designated for that purpose without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities, the Corporation shall execute and the Trustee shall authenticate and make
available for delivery in exchange therefor one or more definitive Securities of the same series, of any authorized denominations having the same Original Issue Date and Stated Maturity and having the same terms as such temporary Securities. Until
so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such series. 
  
 Section 3.5. Global Securities. 
  
 (a) Each Global Security issued under this Indenture shall be registered in the name of the Depositary designated by the
Corporation 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 Securities registered, 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 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 the Corporation is unable to locate a
qualified successor, (ii) the Corporation executes and delivers to the Trustee a Corporation Order stating that the Corporation elects to terminate the book-entry system through the Depositary, (iii) there shall have occurred and be continuing an
Event of Default, or (iv) if the Global Security evidences a Restricted Security, a beneficial interest in 

  

 -30- 

 
such Global Security is transferred to an Institutional Accredited Investor that is not a Qualified Institutional Buyer, upon reasonable prior notice of such
transfer by the Depositary or its authorized representative to the Securities Registrar and (A) delivery to the Securities Registrar of a Restricted Securities Certificate duly authorized by the Depositary or its authorized representative and (B)
delivery to the Securities Registrar and the Corporation of a Institutional Accredited Investor Letter duly executed by the Institutional Accredited Investor. 
  

(c) If any Global Security is to be exchanged for other Securities or cancelled in whole, it shall be surrendered by or on behalf of the Depositary or
its nominee to the Securities Registrar for exchange or cancellation as provided in this Article III. If any Global Security is to be exchanged for other Securities or cancelled 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, subject to Section
3.6(b)(v), or increased by an amount equal to the portion thereof to be so exchanged or cancelled, 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 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 Trustee shall, subject to Section 3.5(b) and as otherwise provided in this Article III, 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, whether pursuant to this Article III, Section 9.6 or 11.6 or otherwise, 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) 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 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 Agent Members. Neither the Trustee nor
the Securities Registrar shall have any liability in respect of any transfers effected by the Depositary. 
  
 (f) 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 Agent Members.

 Section 3.6. Registration, Transfer and Exchange Generally; Certain Transfers and Exchanges;
Securities Act Legends. 
  
 (a) The Corporation shall cause to
be kept at the Corporate Trust Office of the Trustee a register in which, subject to such reasonable regulations as it may prescribe, the Corporation shall provide for the registration of Securities and of transfers of Securities. Such register is
herein sometimes referred to as the “Securities Register.” The Trustee is hereby appointed “Securities Registrar” for the purpose of registering Securities and transfers of Securities as herein provided. 

 
 Upon surrender for registration of transfer of any Security at the offices
or agencies of the Corporation designated for such purpose the Corporation shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series of any
authorized denominations of like tenor and aggregate principal amount and bearing such restrictive legends as may be required by this Indenture. 
  
 At the option of the Holder, Securities may be exchanged for other Securities of the same series of any authorized denominations, of like tenor and
aggregate principal amount and bearing such restrictive legends as may be required by this Indenture, upon surrender of the Securities to be exchanged at such office or agency. Whenever any securities are so surrendered for exchange, the Corporation
shall execute, and the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to receive. 
  
 All Securities issued upon any transfer or exchange of Securities shall be the valid obligations of the Corporation, evidencing the same debt, and
entitled to the same benefits under this Indenture, as the Securities surrendered upon such transfer or exchange. 
  
 Every Security presented or surrendered for transfer or exchange shall (if so required by the Corporation or the Trustee) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the Corporation and the Securities Registrar, duly executed by the Holder thereof or such Holder’s attorney duly authorized in writing. 
  
 No service charge shall be made to a Holder for any transfer or exchange of
Securities, but the Corporation 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. 
  
 Neither the Corporation nor the Trustee shall be required, pursuant to the
provisions of this Section, (i) to issue, register the transfer of or exchange any Security of any series during a period beginning at the opening of business 15 days before the day of selection for redemption of Securities of that series 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. 
  

 -32- 

 (b) Notwithstanding any other provision of this Indenture, transfers and exchanges of Securities and
beneficial interests in a Global Security shall be made only in accordance with this Section 3.6(b). 
  
 (i) Restricted Non-Global Security to Global Security. If the Holder of a Security (other than a Global Security) wishes at
any time to transfer all or any portion of such Security to a Person who wishes to take delivery thereof in the form of a beneficial interest in a Global Security, such transfer may be effected only in accordance with the provisions of this clause
(b)(i) and subject to the Applicable Procedures. Upon receipt by the Securities Registrar of (A) such Security as provided in Section 3.6(a) and instructions satisfactory to the Securities Registrar directing that a beneficial interest in the Global
Security in a specified principal amount not greater than the principal amount of such Security be credited to a specified Agent Member’s account and (B) if the Security evidences a Restricted Security, a Restricted Securities Certificate duly
executed by such Holder or such Holder’s attorney duly authorized in writing, then the Securities Registrar shall cancel such Security (and issue a new Security in respect of any untransferred portion thereof) as provided in Section 3.6(a) and
increase the aggregate principal amount of the Global Security by the specified principal amount as provided as provided in Section 3.5(c). 
  
 (ii) Non-Global Security to Non-Global Security. A Security that is not a Global Security may be transferred, in whole or in
part, to a Person who takes delivery in the form of another Security that is not a Global Security as provided in Section 3.6(a); provided that if the Security to be transferred in whole or in part is a Restricted Security, the Securities
Registrar shall have received a Restricted Securities Certificate duly executed by the transferor Holder or such Holder’s attorney duly authorized in writing. 
  
 (iii) Exchanges Between Global Security and Non-Global Security. A Global Security (or a
beneficial interest therein) beneficial interest in a Global Security may be exchanged for a Security that is not a Global Security as provided in Section 3.5. 
  

(iv) Certain Initial Transfers of Non-Global Securities. In the case of Securities initially issued other than in global
form, an initial transfer or exchange of such Securities that does not involve any change in beneficial ownership may be made to an Institutional Accredited Investor or Investors as if such transfer or exchange were not an initial transfer or
exchange; provided that written certification shall be provided by the transferee and transferor of such Securities to the Securities Registrar that such transfer or exchange does not involve a change in beneficial ownership. 
  
 (v) Transfers to Institutional Accredited Investors.
Notwithstanding any other provision of this Indenture, in connection with a transfer of Restricted Securities or an interest therein to an Institutional Accredited Investor that is not a Qualified Institutional Buyer, such Institutional Accredited
Investor shall be required, prior to such transfer, to furnish to the Corporation and the Securities Registrar a duly 

  

 -33- 

 
executed Institutional Accredited Investor Letter and such other certifications, legal opinions or other information as they or either of them may reasonably
require to confirm that such transfer is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirement of the Securities Act. An Institutional Accredited Investor may not hold a Restricted Security or an
interest therein in the form of a Global Security or any other form intended to facilitate book-entry trading in beneficial interests in such Security. 
  
 (vi) Limitations Relating to Principal Amount. Notwithstanding any other provision of this Indenture and unless otherwise
specified as permitted by Section 3.1, Securities or portions thereof may be transferred or exchanged only in principal amounts of not less than $100,000. Any transfer, exchange or other disposition of Securities in contravention of this Section
3.6(b)(v) shall be deemed to be void and of no legal effect whatsoever, any such transferee shall be deemed not to be the Holder or owner of any beneficial interest in such Securities for any purpose, including but not limited to the receipt of
interest payable on such Securities, and such transferee shall be deemed to have no interest whatsoever in such Securities. 
  
 (c) Except as set forth below, all Securities shall bear a Restricted Securities Legend: 
  
 (i) subject to the following clauses of this Section 3.6(c), a Security or any portion thereof that is
exchanged, upon transfer or otherwise, for a Global Security or any portion thereof shall bear the Restricted Securities Legend borne by such Global Security while represented thereby; 
  
 (ii) subject to the following clauses of this Section 3.6(c), a new Security that is not a Global Security
and is issued in exchange for another Security (including a Global Security) or any portion thereof, upon transfer or otherwise, shall bear the Restricted Securities Legend borne by such other Security while represented thereby; 
  
 (iii) after the date which is two years following the
Original Issue Date of a Security, a new Security (other than a Global Security) which does not bear a Restricted Securities Legend shall, unless the Securities Registrar is otherwise instructed by the Corporation in writing, be issued in exchange
for or in lieu of a Restricted Security or any portion thereof which bears such a legend if the Trustee has received an Unrestricted Securities Certificate, duly executed by the Holder of such legended Restricted Security or his attorney duly
authorized in writing, and after such date and receipt of such certificate, the Trustee shall authenticate and deliver such a new Security in exchange for or in lieu of such other Security as provided in this Article III; 
  
 (iv) a new Security (other than a Global Security) that does
not bear a Restricted Securities Legend may be issued in exchange for or in lieu of a Restricted Security or any portion thereof that bears such a legend if, in the Corporation’s judgment, placing such a legend upon such new Security is not
necessary to ensure compliance with the registration requirements of the Securities Act, and the Trustee, 

  

 -34- 

 
at the written direction of the Corporation in the form of an Officers’ Certificate, shall authenticate and deliver such a new Security as provided in
this Article III; 
  
 (v) Securities distributed
to a holder of Capital Securities upon dissolution of an Issuer Trust shall bear a Restricted Securities Legend if the Capital Securities so held bear a similar legend; and 
  
 (vi) notwithstanding the foregoing provisions of this Section 3.6(c), a Successor Security of a Security
that does not bear a Restricted Securities Legend shall not bear such form of legend unless the Corporation has reasonable cause to believe that such Successor Security is a “restricted security” within the meaning of Rule 144, in which
case the Trustee, at the written direction of the Corporation in the form of an Officers’ Certificate, shall authenticate and deliver a new Security bearing a Restricted Securities Legend in exchange for such Successor Security as provided in
this Article III. 
  
 Section 3.7. Mutilated, Destroyed, Lost
and Stolen Securities. 
  
 If any mutilated Security is
surrendered to the Trustee together with such security or indemnity as may be required by the Corporation or the Trustee to save each of them harmless, the Corporation shall execute and the Trustee shall authenticate and deliver in exchange therefor
a new Security of the same series, of like tenor and aggregate principal amount, bearing the same legends, and bearing a number not contemporaneously outstanding. 
  
 If there shall be delivered to the Corporation 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 Corporation or the Trustee that such Security has been acquired by a protected
purchaser, the Corporation shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series, of like tenor and aggregate principal amount and
bearing the same legends as such destroyed, lost or stolen Security, and bearing a number not contemporaneously outstanding. 
  
 If any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Corporation in its discretion may, instead
of issuing a new Security, pay such Security. 
  
 Upon the
issuance of any new Security under this Section, the Corporation 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. 
  
 Every new
Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Corporation, whether or not the 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 of the same series duly issued hereunder. 
  

 -35- 

 The provisions of this Section 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 3.8. Payment of Interest and Additional Interest; Interest Rights Preserved. 
  
 Interest and Additional Interest on any Security of any series 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 in respect of Securities of such
series, except that, unless otherwise provided in the Securities of such series, interest and any Additional Interest payable on the Stated Maturity of the principal of a Security shall be paid to the Person to whom principal is paid. The initial
payment of interest on any Security of any series that is issued between a Regular Record Date and the related Interest Payment Date shall be payable as provided in such Security or in the Board Resolution pursuant to Section 3.1 with respect to the
related series of Securities. 
  
 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 of such series (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 Corporation, at its election in each case, as provided in Clause (1) or (2) below: 
  
 (1) The Corporation may elect to make payment of any
Defaulted Interest to the Persons in whose names the Securities of such series in respect of which interest is in default (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment
of such Defaulted Interest, which shall be fixed in the following manner. The Corporation shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed
payment, and at the same time the Corporation 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 as in this Clause provided. Thereupon the Trustee shall fix a Special Record Date for
the payment of such Defaulted Interest, which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Corporation of such Special Record Date and, in the name and at the expense of the Corporation, 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 of such series at the address of such Holder as it appears in the Securities Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in
the name and at the expense of the Corporation, 

  

 -36- 

 
cause a similar notice to be published at least once in a newspaper, customarily published in the English language on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record
Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following Clause (2). 
  
 (2) The Corporation may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Securities of the series in respect of which interest is in default may be listed and, upon such notice as may be required by such exchange (or by the Trustee if the Securities are not listed), if, after notice given
by the Corporation to the Trustee of the proposed payment pursuant to this Clause, such payment shall be deemed practicable by the Trustee. 
  
 Subject to the foregoing provisions of this Section, 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 3.9. Persons Deemed Owners. 
  
 The Corporation, the Trustee and any agent of the Corporation 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 (subject to Section 3.8) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Corporation, the Trustee
nor any agent of the Corporation or the Trustee shall be affected by notice to the contrary. 
  
 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
Corporation, the Trustee and any agent of the Corporation or the Trustee as the owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the Corporation, the Trustee or any agent of the
Corporation 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 3.10. 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 Corporation may at any time deliver to the Trustee for 

  

 -37- 

 
cancellation any Securities previously authenticated and delivered hereunder that the Corporation 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, except as expressly permitted by this Indenture. All canceled
Securities shall be returned to the Corporation by the Trustee. 
  
 Section 3.11. Computation of Interest. 
  
 Except
as otherwise specified as contemplated by Section 3.1 for Securities of any series, interest on the Securities of each series for any partial period shall be computed on the basis of a 360-day year of twelve 30-day months and the actual number of
days elapsed in any partial month in such period, and interest on the Securities of each series for a full period shall be computed by dividing the rate per annum by the number of interest periods that together constitute a full twelve months.

  
 Section 3.12. Deferrals of Interest Payment Dates.

  
 If specified as contemplated by Section 2.1 or Section 3.1
with respect to the Securities of a particular series, so long as no Event of Default has occurred and is continuing, the Corporation shall have the right, at any time during the term of such series, from time to time to defer the payment of
interest on such Securities for such period or periods as may be specified as contemplated by Section 3.1 (each, an “Extension Period”), during which Extension Periods the Corporation shall, if so specified as contemplated by
Section 3.1, have the right to make partial payments of interest on any Interest Payment Date. No Extension Period shall end on a date other than an Interest Payment Date. At the end of any such Extension Period the Corporation shall pay all
interest then accrued and unpaid on the Securities (together with Additional Interest thereon, if any, at the rate specified for the Securities of such series to the extent permitted by applicable law) to the Persons in whose names the Securities
are registered at the close of business on the Regular Record Date; provided, however, that no Extension Period shall extend beyond the Stated Maturity of the principal of the Securities of such series; and provided further,
however, that during any such Extension Period, the Corporation shall not (i) make any payment of principal of or interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Corporation that rank pari
passu in all respects with or junior in interest to the Securities of such series, (ii) make any guarantee payments (other than payments under any guarantee agreement specified as contemplated by Section 3.1) with respect to any guarantee by the
Corporation of the debt securities of any subsidiary of the Corporation if such guarantee ranks pari passu in all respects with or junior in interest to Securities issued to an Issuer Trust or (iii) declare or pay any dividends or
distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any of the Corporation’s capital stock (other than (a) repurchases, redemptions or other acquisitions of shares of capital stock of the Corporation in
connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of any one or more employees, officers, directors or consultants, in connection with a dividend reinvestment or stockholder stock purchase
plan or in connection with the issuance of capital stock of the Corporation (or securities convertible into or exercisable for such capital stock) as consideration in an acquisition transaction entered into prior to the 

  

 -38- 

 
applicable Extension Period, (b) as a result of an exchange or conversion of any class or series of the Corporation’s capital stock (or any capital
stock of a Subsidiary of the Corporation) for any class or series of the Corporation’s capital stock or of any class or series of the Corporation’s indebtedness for any class or series of the Corporation’s capital stock, (c) the
purchase of fractional interests in shares of the Corporation’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged, (d) any declaration of a dividend in connection
with any Rights Plan, or the issuance of rights, stock or other property under any Rights Plan, or the redemption or repurchase of rights pursuant thereto, or (e) any dividend in the form of stock, warrants, options or other rights where the
dividend stock or the stock issuable upon exercise of such warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks pari passu with or junior to such stock). Prior to the termination of any such
Extension Period, the Corporation may further defer the payment of interest, provided that no Event of Default has occurred and is continuing, and provided further, that no Extension Period shall exceed the period or periods specified
in such Securities, extend beyond the Stated Maturity of the principal of such Securities or end on a date other than an Interest Payment Date. 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 Corporation may elect to begin a new Extension Period, subject to the above conditions. No interest or Additional 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 as and to the extent as may be specified as contemplated by Section 3.1. The
Corporation shall give the Holders of the Securities of such series and the Trustee notice of its election to begin any such Extension Period at least five Business Days prior to the next succeeding Interest Payment Date on which interest on
Securities of such series would be payable but for such deferral or, with respect to any Securities of a series issued to an Issuer Trust, so long as any such Securities are held by such Issuer Trust, at least five Business Days prior to the earlier
of (i) the next succeeding date on which Distributions on the Capital Securities of such Issuer Trust would be payable but for such deferral, and (ii) the date on which the Property Trustee of such Issuer Trust is required to give notice to holders
of such Capital Securities of the record date or the date such Distributions are payable. 
  
 The Trustee shall promptly give notice of the Corporation’s election to begin any such Extension Period to the Holders of the Outstanding Securities of such series. 
  
 Section 3.13. Right of Set-Off. 
  
 With respect to the Securities of a series initially issued to an Issuer
Trust, notwithstanding anything to the contrary herein, the Corporation shall have the right to set off any payment it is otherwise required to make in respect of any such Security to the extent the Corporation 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 Capital Securities pursuant to an action undertaken under Section 5.8 of this Indenture. 
  

 -39- 

 Section 3.14. Agreed Tax Treatment. 
  
 Each Security issued hereunder shall provide that the Corporation and, by its acceptance of a Security or a beneficial
interest therein, the Holder of, and any Person that acquires a beneficial interest in, such Security agree that for United States Federal, state and local tax purposes it is intended that such Security constitutes indebtedness. 
  
 Section 3.15. Shortening or Extension of Stated Maturity. 

 
 If specified as contemplated by Section 2.1 or Section 3.1 with respect to
the Securities of a particular series, the Corporation shall have the right to (i) shorten the Stated Maturity of the principal of the Securities of such series at any time to any date, and (ii) extend the Stated Maturity of the principal of the
Securities of such series at any time at its election for one or more periods, provided that, if the Corporation elects to exercise its right to extend the Stated Maturity of the principal of the Securities of such series pursuant to Clause
(ii) above, at the time such election is made and at the time of extension, such conditions as may be specified in such Securities shall have been satisfied. 
  
 Section 3.16. CUSIP Numbers. 
  
 The Corporation 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.

 and the Corporation, in the case of subclause (B)(i), (ii) or
(iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose an amount in the currency or currencies in which the Securities of such series are payable sufficient to pay and discharge the entire

 -41- 

 
premium, if any) and interest (including any Additional Interest) for the payment of which such money or obligations have been deposited with or received by
the Trustee. 
  
 ARTICLE V 
  
 REMEDIES 
  
 Section 5.1. Events of Default. 
  
 “Event of Default”, wherever used herein with respect to the
Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental body) except as may be specified pursuant to Section 3.1: 
  
 (1) default in the payment of any interest upon any Security of that series, including any Additional Interest in respect thereof, when it
becomes due and payable, and continuance of such default for a period of 30 days (subject to the deferral of any due date in the case of an Extension Period); or 
  
 (2) default in the payment of the principal of (or premium, if any, on) any Security of that series at its
Maturity; or 
  
 (3) failure on the part of the
Corporation duly to observe or perform any other of the covenants or agreements on the part of the Corporation in the Securities of that series or in this Indenture for a period of 90 days after the date on which written notice of such failure,
requiring the Corporation to remedy the same, shall have been given by registered or certified mail to the Corporation by the Trustee or to the Corporation and the Trustee by the Holders of at least 25% in aggregate principal amount of the
Outstanding Securities of that series; or 
  
 (4)
the entry of a decree or order by a court having jurisdiction in the premises adjudging the Corporation a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization of the Corporation under the Bankruptcy Code or any
other similar applicable Federal or State law, which decree or order shall have continued undischarged and unstayed for a period of 60 days; or the entry of a decree or order of a court having jurisdiction in the premises for the appointment of a
receiver or liquidator or trustee or assignee in bankruptcy or insolvency of the Corporation or of its property, or for the winding up or liquidation of its affairs, which decree or order shall have continued undischarged and unstayed for a period

 (5) the commencement by the

 -42- 

 
any such petition, or the consent by the Corporation to the appointment of a receiver or liquidator or trustee or assignee in bankruptcy or insolvency of it
or of its property, or the making by the Corporation of an assignment for the benefit of creditors, or the admission by the Corporation in writing of its inability to pay its debts generally as they become due; or 
  
 (6) any other Event of Default provided with respect to
Securities of such series specified as contemplated by Section 3.1. 
  
 Section 5.2. Acceleration of Maturity; Rescission and Annulment. 
  
 If an Event of Default (other than an Event of Default specified in Section 5.1(4) or 5.1(5)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then and in every such case the
Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all the Securities of that series to be due and payable immediately, by a notice in writing to the Corporation (and to the Trustee if given by Holders), provided that, in the case of
the Securities of a series issued to an Issuer Trust, if, upon an Event of Default, the Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of such series fail to declare the principal of all the Outstanding
Securities of such series to be immediately due and payable, the holders of at least 25% in aggregate Liquidation Amount (as defined in the related Trust Agreement) of the related series of Capital Securities issued by such Issuer Trust then
outstanding shall have the right to make such declaration by a notice in writing to the Corporation and the Trustee; and upon any such declaration such principal amount (or specified portion thereof) of and the accrued interest (including any
Additional Interest) on all the Securities of such series shall become immediately due and payable. If an Event of Default specified in Section 5.1(4) or 5.1(5) with respect to Securities of any series at the time Outstanding occurs, the principal
amount of all the Securities of such series (or, if the Securities of such series are Discount Securities, such portion of the principal amount of such Securities as may be specified by the terms of that series) shall automatically, and without any
declaration or other action on the part of the Trustee or any Holder, become immediately due and payable. Payment of principal and interest (including any Additional Interest) on such Securities shall remain subordinated to the extent provided in
Article XIII notwithstanding that such amount shall become immediately due and payable as herein provided. 
  
 At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of
the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in aggregate principal amount of the Outstanding Securities of that series, by written notice to the Corporation and the Trustee, may
rescind and annul such declaration and its consequences if: 
  
 (1) the Corporation has paid or deposited with the Trustee a sum sufficient to pay: 
  
 (A) all matured installments of interest on all Securities of such series, 
  

 -43- 

 (B) any accrued Additional Interest on all Securities of such series, 
  
 (C) the principal of (and premium, if any, on) any
Securities of such series that have become due otherwise than by such declaration of acceleration and interest and Additional Interest thereon at the rate borne by the Securities, and 
  
 (D) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel; and 
  
 (2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series that has become due solely by such acceleration, have been cured or waived
as provided in Section 5.13. 
  
 In the case of Securities of a
series initially issued to an Issuer Trust, if the Holders of such Securities fail to annul such declaration and waive such default, the holders of a majority in aggregate Liquidation Amount (as defined in the related Trust Agreement) of the related
series of Capital Securities issued by such Issuer Trust then outstanding shall also have the right to rescind and annul such declaration and its consequences by written notice to the Corporation and the Trustee, subject to the satisfaction of the
conditions set forth in Clauses (1) and (2) above of this Section 5.2. 
  
 No such rescission shall affect any subsequent default or impair any right consequent thereon. 
  
 Section 5.3. Collection of Indebtedness and Suits for Enforcement by Trustee. 
  
 The Corporation covenants that if: 
  

(1) default is made in the payment of any installment of interest (including any Additional Interest) on any Security of any series
when such interest becomes due and payable and such default continues for a period of 30 days, or 
  
 (2) default is made in the payment of the principal of (and premium, if any, on) any Security at the Maturity thereof, 
  
 the Corporation will, upon demand of the Trustee, pay to the Trustee, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such Securities for principal, including any sinking fund payment or analogous obligations (and premium, if any) and interest (including any Additional Interest), and, in addition
thereto, all amounts owing the Trustee under Section 6.7. 
  

 -44- 

 If the Corporation fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and
as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, and may prosecute such proceeding to judgment or final decree, and may enforce the same against the Corporation or any other
obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Corporation or any other obligor upon the Securities, wherever situated. 
  
 If an Event of Default with respect to Securities of any series occurs and is
continuing, the Trustee is authorized to proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings, whether for the specific enforcement of any covenant or agreement
in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
  
 Section 5.4. Trustee May File Proofs of Claim. 
  
 In case of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding
relative to the Corporation or any other obligor upon the Securities or the property of the Corporation or of such other obligor or their creditors, 
  
 (a) the Trustee (irrespective of whether the principal of the Securities of any series shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Corporation for the payment of overdue principal (and premium, if any) or interest (including any Additional Interest)) shall be entitled and
empowered, by intervention in such proceeding or otherwise, 
  
 (i) to file and prove a claim for the whole amount of principal (and premium, if any) and interest (including any Additional Interest) owing and unpaid in respect to the Securities and to file such other papers or
documents as may be necessary or advisable and to take any and all actions as are authorized under the Trust Indenture Act in order to have the claims of the Holders and any predecessor to the Trustee under Section 6.7 allowed in any such judicial
proceedings; and 
  
 (ii) in particular, the
Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same in accordance with Section 5.6; and 
  
 (b) any custodian, receiver, assignee, trustee, liquidator, sequestrator (or other similar official) in any
such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee for distribution in accordance with Section 5.6, and in the event that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it and any predecessor Trustee under Section 6.7. 
  

 -45- 

 Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or
adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such
proceeding; provide, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee. 
  
 Section 5.5. Trustee May Enforce Claim Without Possession of
Securities. 
  
 All rights of action and claims under this
Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be
brought in its own name as trustee of an express trust, and any recovery of judgment shall, subject to Article XIII and after provision for the payment of all the amounts owing the Trustee and any predecessor Trustee under Section 6.7, its agents
and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been recovered. 
  
 Section 5.6. Application of Money Collected. 
  
 Any money or property collected or to be applied by the Trustee with respect to a series of Securities pursuant to this Article shall be applied in the

series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture or for the appointment of a receiver, assignee, trustee, liquidator, sequestrator (or other similar official) or for any other remedy
hereunder, unless: 
  
 (1) such Holder has
previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; 
  

 -46- 

 (2) the Holders of not less than 25% in aggregate principal amount of the Outstanding
Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
  
 (3) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and
liabilities to be incurred in compliance with such request; 
  
 (4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and 
  
 (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day
period by the Holders of a majority in aggregate principal amount of the Outstanding Securities of that series; 
  
 it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing itself of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders of Securities, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner
herein provided and for the equal and ratable benefit of all such Holders. 
  
 Section 5.8. Unconditional Right of Holders to Receive Principal, Premium and Interest; Direct Action by Holders of Capital Securities. 
  
 Notwithstanding any other provision in this Indenture, the Holder of any Security of any series shall have the right, which
is absolute and unconditional, to receive payment of the principal of (and premium, if any) and (subject to Sections 3.8 and 3.12) interest (including any Additional Interest) on such Security on the respective Stated Maturities expressed in such
Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such right shall not be impaired without the consent of such Holder. In the case of Securities of a series issued to
an Issuer Trust, any registered holder of the series of Capital Securities issued by such Issuer Trust shall have the right, upon the occurrence of an Event of Default described in Section 5.1(1) or 5.1(2), to institute a suit directly against the
Corporation for enforcement of payment to such holder of principal of (premium, if any) and (subject to Sections 3.8 and 3.12) interest (including any Additional Interest) on the Securities having a principal amount equal to the aggregate
Liquidation Amount (as defined in the related Trust Agreement) of such Capital Securities held by such holder. 
  
 Section 5.9. Restoration of Rights and Remedies. 
  
 If the Trustee, any Holder or any holder of Capital Securities issued by any Issuer Trust has instituted any proceeding to enforce any right or remedy
under this Indenture and 

  

 -47- 

 
such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee, such Holder or such holder of Capital
Securities, then and in every such case the Corporation, the Trustee, such Holders and such holder of Capital Securities shall, subject to any determination in such proceeding, be restored severally and respectively to their former positions
hereunder, and thereafter all rights and remedies of the Trustee, such Holder and such holder of Capital Securities shall continue as though no such proceeding had been instituted. 
  
 Section 5.10. Rights and Remedies Cumulative. 
  
 Except as otherwise provided in the last paragraph of Section 3.7, no right or remedy herein conferred upon or reserved to
the Trustee or the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter
existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. 
  
 Section 5.11. Delay or Omission Not Waiver. 
  
 No delay or omission of the Trustee, any Holder of any Security with respect
to the Securities of the related series or any holder of any Capital Security to exercise any right or remedy accruing upon any Event of Default with respect to the Securities of the related series shall impair any such right or remedy or constitute
a waiver of any such Event of Default or an acquiescence therein. 
  
 Every right and remedy given by this Article or by law to the Trustee or to the Holders and the right and remedy given to the holders of Capital Securities by Section 5.8 may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee, the Holders or the holders of Capital Securities, as the case may be. 
  
 Section 5.12. Control by Holders. 
  
 The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of any series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that: 
  
 (1) such direction shall not be in conflict with any rule of
law or with this Indenture, 
  
 (2) the Trustee
may take any other action deemed proper by the Trustee that is not inconsistent with such direction, and 
  
 (3) subject to the provisions of Section 6.1, the Trustee shall have the right to decline to follow such direction if a Responsible
Officer or Responsible Officers of the Trustee shall, in good faith, determine that the proceeding so directed 

  

 -48- 

 
would be unjustly prejudicial to the Holders not joining in any such direction or would involve the Trustee in personal liability. 
  
 Section 5.13. Waiver of Past Defaults. 
  
 The Holders of not less than a majority in aggregate principal amount of the
Outstanding Securities of any series affected thereby and, in the case of any Securities of a series initially issued to an Issuer Trust, the holders of a majority in aggregate Liquidation Amount (as defined in the related Trust Agreement) of the
Capital Securities issued by such Issuer Trust may waive any past default hereunder and its consequences with respect to such series except a default: 
  
 (1) in the payment of the principal of (or premium, if any) or interest (including any Additional Interest) on any Security of such series
(unless such default has been cured and the Corporation has paid to or deposited with the Trustee a sum sufficient to pay all matured installments of interest (including any Additional Interest) and all principal of (and premium, if any, on) all
Securities of that series due otherwise than by acceleration), or 
  
 (2) in respect of a covenant or provision hereof that under Article IX cannot be modified or amended without the consent of each Holder of any Outstanding Security of such series affected. 
  
 Any such waiver shall be deemed to be on behalf of the Holders of all the
Securities of such series or, in the case of a waiver by holders of Capital Securities issued by such Issuer Trust, by all holders of Capital Securities issued by such Issuer Trust. 
  
 Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have
been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 
  
 Section 5.14. Undertaking for Costs. 
  
 All parties to this Indenture agree, and each Holder of any Security by his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to
pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal
amount of the Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if any) or interest (including any Additional Interest) on any Security on or after the
respective Stated Maturities expressed in such Security. 
  

 -49- 

 Section 5.15. Waiver of Usury, Stay or Extension Laws. 
  
 The Corporation covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the
performance of this Indenture; and the Corporation (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein
granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

 (b) In case an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. 
  
 (c) No provision of this Indenture shall be construed to relieve the Trustee

 (1) this SubSection shall not be construed to limit the effect of SubSection (a) of this Section; 
  
 (2) the Trustee shall not be liable for any error of

however, that, except in the case of a default in the payment of the principal of (or premium, if any) or interest (including any Additional Interest) on any Security of such series, the Trustee shall be protected in withholding such notice if
and so long as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders of Securities
of such series; and provided further, that, in the case of any default of the character specified in Section 5.1(3), no such notice to Holders of Securities of such series shall be given until at least 30 days after the occurrence thereof.

 Section 6.4. Not Responsible for Recitals or Issuance of Securities. 
  
 The recitals contained herein and in the Securities, except the
Trustee’s certificates of authentication, shall be taken as the statements of the Corporation, and neither the Trustee nor any Authenticating Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the
validity or sufficiency of this Indenture or of the Securities. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Corporation of the Securities or the proceeds thereof.

 The Trustee, any Authenticating Agent, any Paying Agent, any Securities
Registrar or any other agent of the Corporation, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 6.8 and 6.13, may otherwise deal with the Corporation with the same rights it would have

hereunder, including the costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. This indemnification shall survive the termination of this
Indenture and the resignation or removal of the Trustee. 
  

 -53- 

 When the Trustee incurs expenses or renders services after an Event of Default specified in Section

supervision or examination by Federal or State authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then, for the purposes of
this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. Neither the Corporation nor any Person directly or indirectly controlling, controlled by or under

successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee under Section 6.11. 
  
 (b) The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Corporation. If an

 (c) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in aggregate principal amount of the Outstanding Securities of such series, delivered to the Trustee and to the
Corporation. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal, the Trustee being removed may petition any court of competent jurisdiction for
the appointment of a successor Trustee with respect to the Securities of such series.

 (1) the Trustee shall fail to comply with Section 6.8 after written request therefor by the Corporation or by any Holder who has been a bona fide Holder of a Security for at least six months, or 
  
 (2) the Trustee shall cease to be eligible under Section 6.9
and shall fail to resign after written request therefor by the Corporation or by any such Holder, or 
  
 (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
  
 then, in any such case, (i) the Corporation, acting pursuant to the authority of a Board Resolution, may remove the Trustee with respect to
the Securities of all series issued hereunder, or (ii) subject to Section 5.14, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of such Holder and all others similarly situated, petition any court of

Trustee for any cause with respect to the Securities of one or more series, the Corporation, by a Board Resolution, shall promptly appoint a successor Trustee with respect to the Securities of that or those series. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee 

  

 -55- 

 
with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in aggregate principal amount of the Outstanding
Securities of such series delivered to the Corporation and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee with respect to the Securities of such series
and supersede the successor Trustee appointed by the Corporation. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Corporation or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, subject to Section 5.14, on behalf of such Holder and all others similarly situated, petition any court of competent jurisdiction for the
appointment of a successor Trustee with respect to the Securities of such series. 
  
 (f) The Corporation shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any

Trustee with respect to the Securities of such series and the address of its Corporate Trust Office. 
  
 Section 6.11. Acceptance of Appointment by Successor. 
  
 (a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor Trustee so appointed shall execute,
acknowledge and deliver to the Corporation and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further
act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Corporation or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute
and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee
hereunder. 
  
 (b) In case of the appointment hereunder of a
successor Trustee with respect to the Securities of one or more (but not all) series, the Corporation, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment and which (i) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights,
powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (ii) if the retiring Trustee is not retiring with respect to all Securities, shall
contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not
retiring shall continue to be vested in the retiring Trustee, and (iii) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one
Trustee, it being understood that 

  

 -56- 

 
nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of
a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall
become effective to the extent provided therein and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts, and duties of the retiring Trustee with respect to the Securities
of that or those series to which the appointment of such successor Trustee relates; but, on request of the Corporation or any successor Trustee, such retiring Trustee shall duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates. 
  

(c) Upon request of any such successor Trustee, the Corporation shall execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all rights, powers and trusts referred to in paragraph (a) or (b) of this Section, as the case may be. 
  
 (d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under
this Article. 
  
 Section 6.12. Merger, Conversion,
Consolidation or Succession to Business. 
  
 Any corporation
into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or
substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper
or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee
may adopt such authentication and deliver the Securities so authenticated, and in case any Securities shall not have been authenticated, any such successor to the Trustee may authenticate such Securities either in the name of any predecessor Trustee
or in the name of such successor Trustee, and in all cases the certificate of authentication shall have the full force which it is provided anywhere in the Securities or in this Indenture that the certificate of the Trustee shall have. 

 
 Section 6.13. Preferential Collection of Claims Against
Corporation. 
  
 If and when the Trustee shall be or become a
creditor of the Corporation (or any other obligor upon the Securities), the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Corporation (or any such other obligor).

 The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities, which shall be authorized to act on behalf of
the Trustee to authenticate Securities of such series issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.6, and Securities so authenticated shall be entitled to the benefits
of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s
certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Corporation and shall at all times be a
corporation organized and doing business under the laws of the United States of America, or of any State or Territory thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and
surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising
or examining authority, then for the purposes of this Section the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If
at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. 
  
 Any corporation into which an Authenticating Agent may be merged or converted
or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate trust
business of an Authenticating Agent shall be the successor Authenticating Agent hereunder, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the
Trustee or the Authenticating Agent. 
  
 An Authenticating Agent
may resign at any time by giving written notice thereof to the Trustee and to the Corporation. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the
Corporation. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor
Authenticating Agent, which shall be acceptable to the Corporation and shall give notice of such appointment in the manner provided in Section 1.6 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve.
Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provision of this Section. 
  

 -58- 

 The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its
services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 6.7. 
  
 If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed thereon, in
addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 
  
 This is one of the Securities of the series designated therein referred to in the within mentioned Indenture.

 ARTICLE X 
  
 COVENANTS 
  
 Section 10.1. Payment of Principal, Premium and Interest. 
  
 The Corporation covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of (and premium, if
any) and interest (including any Additional Interest) on the Securities of that series in accordance with the terms of such Securities and this Indenture. 
  
 Section 10.2. Maintenance of Office or Agency. 
  
 The Corporation will maintain in each Place of Payment for any series of Securities an office or agency where Securities of that series may be presented
or surrendered for 

  

 -65- 

 
payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Corporation
in respect of the Securities of that series and this Indenture may be served. The Corporation initially appoints the Trustee, acting through its Corporate Trust Office, as its agent for said purposes. The Corporation will give prompt written notice
to the Trustee of any change in the location of any such office or agency. If at any time the Corporation shall fail to maintain such office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders,
notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Corporation hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
  
 The Corporation may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for any or all of such purposes, and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner
relieve the Corporation of its obligation to maintain an office or agency in each Place of Payment for Securities of any series for such purposes. The Corporation will give prompt written notice to the Trustee of any such designation and any change
in the location of any such office or agency. 
  
 Section 10.3.
Money for Security Payments to be Held in Trust. 
  
 If the
Corporation shall at any time act as its own Paying Agent with respect to any series of Securities, it will, on or before each due date of the principal of (and premium, if any) or interest on any of the Securities of such series, segregate and hold
in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal (and premium, if any) or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and will
promptly notify the Trustee of its failure so to act. 
  
 Whenever
the Corporation shall have one or more Paying Agents, it will, prior to 10:00 a.m., New York City time, on each due date of the principal of (or premium, if any) or interest (including any Additional Interest) on any Securities, deposit with a
Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest (including any Additional Interest) so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal (and premium, if any) or
interest (including any Additional Interest), and (unless such Paying Agent is the Trustee) the Corporation will promptly notify the Trustee of its failure so to act. 
  
 The Corporation will cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: 
  
 (1) hold all sums held by it for the payment of the principal of (and premium, if any) or interest (including any Additional Interest) on
the Securities of a series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 
  

 -66- 

 (2) give the Trustee notice of any default by the Corporation (or any other obligor upon
such Securities) in the making of any payment of principal (and premium, if any) or interest (including any Additional Interest) in respect of any Security of any Series; 
  
 (3) at any time during the continuance of any default with respect to a series of Securities, upon the
written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent with respect to such series; and 
  
 (4) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent. 
  
 The Corporation may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or by Corporation Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Corporation or such Paying Agent, such sums to be held by the Trustee
upon the same trusts as those upon which such sums were held by the Corporation or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such
money. 
  
 Any money deposited with the Trustee or any Paying
Agent, or then held by the Corporation in trust for the payment of the principal of (and premium, if any) or interest (including any Additional Interest) on any Security and remaining unclaimed for two years after such principal (and premium, if
any) or interest has become due and payable shall (unless otherwise required by mandatory provision of applicable escheat or abandoned or unclaimed property law) be paid on Corporation Request to the Corporation, or (if then held by the Corporation)
shall (unless otherwise required by mandatory provision of applicable escheat or abandoned or unclaimed property law) be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the
Corporation for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Corporation as trustee thereof, shall thereupon cease; provided, however, that the Trustee or
such Paying Agent, before being required to make any such repayment, may at the expense of the Corporation cause to be published once, in a newspaper published in the English language, customarily published on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such
money then remaining will be repaid to the Corporation. 
  
 Section 10.4. Statement as to Compliance. 
  
 The
Corporation shall deliver to the Trustee, within 120 days after the end of each fiscal year of the Corporation ending after the date hereof, an Officers’ Certificate covering the preceding calendar year, stating whether or not to the best
knowledge of the signers thereof the Corporation is in default in the performance, observance or fulfillment of or compliance with any of the terms, provisions, covenants and conditions of this Indenture, and 

  

 -67- 

 
if the Corporation shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. For the purpose of
this Section 10.4, compliance shall be determined without regard to any grace period or requirement of notice provided pursuant to the terms of this Indenture. 
  

Section 10.5. Waiver of Certain Covenants. 
  
 Subject to the rights of holders of Capital Securities specified in Section 9.2, if any, the Corporation may omit in any particular instance to comply
with any covenant or condition provided pursuant to Section 3.1, 9.1(3) or 9.1(4) with respect to the Securities of any series, if before or after the time for such compliance the Holders of at least a majority in aggregate principal amount of the
Outstanding Securities of such series shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such covenant or condition, but no such waiver shall extend to or affect such covenant or condition
except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Corporation in respect of any such covenant or condition shall remain in full force and effect. 
  
 Section 10.6. Additional Sums. 
  
 In the case of the Securities of a series initially issued to an Issuer
Trust, and except as otherwise specified as contemplated by Section 2.1 or Section 3.1, if and for so long as (i) an Issuer Trust is the Holder of all of the Outstanding Securities of such series, and (ii) a Tax Event has occurred and is continuing
in respect of such Issuer Trust, the Corporation shall pay to such Issuer Trust (and its permitted successors or assigns under the related Trust Agreement) for so long as such Issuer Trust (or its permitted successor or assignee) is the registered
holder of the Outstanding Securities of such series, such additional amounts as may be necessary in order that the amount of Distributions (including any Additional Amounts (as defined in such Trust Agreement)) then due and payable by such Issuer
Trust on the related Capital Securities and Common Securities that at any time remain outstanding in accordance with the terms thereof shall not be reduced as a result of any Additional Taxes arising from such Tax Event; provided, however,
that Additional Sums shall not include any withholding taxes arising after the occurrence of a Tax Event and which have been withheld from payments to Holders of Trust Securities and for which Holders are liable (the ”Additional
Sums”). Whenever in this Indenture or the Securities there is a reference in any context to the payment of principal of or interest on the Securities, such mention shall be deemed to include mention of the payments of the Additional Sums
provided for in this paragraph to the extent that, in such context, Additional Sums are, were or would be payable in respect thereof pursuant to the provisions of this paragraph and express mention of the payment of Additional Sums (if applicable)
in any provisions hereof shall not be construed as excluding Additional Sums in those provisions hereof where such express mention is not made; provided, however, that the deferral of the payment of interest pursuant to Section 3.12 or
the Securities shall not defer the payment of any Additional Sums that may be due and payable. 
  

 -68- 

 Section 10.7. Additional Covenants. 
  
 The Corporation covenants and agrees with each Holder of Securities of each series that it shall not (i) make any payment of
principal of or interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Corporation that rank pari passu in all respects with or junior in interest to the Securities of such series, (ii) make any guarantee
payments (other than payments under any guarantee agreement specified as contemplated by Section 3.1) with respect to any guarantee by the Corporation of the debt securities of any subsidiary of the Corporation if such guarantee ranks pari passu
in all respects with or junior in interest to Securities issued to an Issuer Trust or (iii) declare or pay any dividends or distributions on, or redeem purchase, acquire or make a liquidation payment with respect to, any shares of the
Corporation’s capital stock (other than (a) repurchases, redemptions or other acquisitions of shares of capital stock of the Corporation in connection with any employment contract, benefit plan or other similar arrangement with or for the
benefit of any one or more employees, officers, directors or consultants, in connection with a dividend reinvestment or stockholder stock purchase plan or in connection with the issuance of capital stock of the Corporation (or securities convertible
into or exercisable for such capital stock) as consideration in an acquisition transaction entered into prior to the applicable Extension Period, (b) as a result of an exchange or conversion of any class or series of the Corporation’s capital
stock (or any capital stock of a Subsidiary of the Corporation) for any class or series of the Corporation’s capital stock or of any class or series of the Corporation’s indebtedness for any class or series of the Corporation’s
capital stock, (c) the purchase of fractional interests in shares of the Corporation’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged, (d) any declaration of a
dividend in connection with any Rights Plan, or the issuance of rights, stock or other property under any Rights Plan, or the redemption or repurchase of rights pursuant thereto, or (e) any dividend in the form of stock, warrants, options or other
rights where the dividend stock or the stock issuable upon exercise of such warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks pari passu with or junior to such stock) if at such time (I)
there shall have occurred any event (A) of which the Corporation has actual knowledge that with the giving of notice or the lapse of time, or both, would constitute an Event of Default with respect to the Securities of such series, and (B) which the
Corporation shall not have taken reasonable steps to cure, (II) if the Securities of such series are held by an Issuer Trust, the Corporation shall be in default with respect to its payment of any obligations under the Guarantee Agreement relating
to the Capital Securities issued by such Issuer Trust, or (iii) the Corporation shall have given notice of its election to begin an Extension Period with respect to the Securities of such series as provided herein and shall not have rescinded such
notice, or such Extension Period, or any extension thereof, shall be continuing. 
  
 The Corporation also covenants with each Holder of Securities of a series issued to an Issuer Trust (i) to hold, directly or indirectly, 100% of the Common Securities of such Issuer Trust, provided that any
permitted successor of the Corporation hereunder may succeed to the Corporation’s ownership of such Common Securities, (ii) as holder of such Common Securities, not to voluntarily terminate, wind-up or liquidate such Issuer Trust, other than
(a) in connection with a distribution of the Securities of such series to the holders of the related Capital Securities in liquidation of such Issuer Trust, or (b) in connection with certain 

  

 -69- 

 
mergers, consolidations or amalgamations permitted by the related Trust Agreement, and (iii) to use its reasonable efforts, consistent with the terms and
provisions of such Trust Agreement, to cause such Issuer Trust to continue to be taxable as a grantor trust and not to be taxable as a corporation for United States federal income tax purposes. 
  
 Section 10.8. Original Issue Discount. 
  
 For each year during which any Securities that were issued with original
issue discount are Outstanding, the Corporation shall furnish to each Paying Agent in a timely fashion such information as may be reasonably requested by each Paying Agent in order that each Paying Agent may prepare the information which it is
required to report for such year on Internal Revenue Service Forms 1096 and 1099 pursuant to Section 6049 of the Internal Revenue Code of 1986, as amended. Such information shall include the amount of original issue discount includible in income for
each $1,000 of principal amount at Stated Maturity of outstanding Securities during such year. 
  
 ARTICLE XI 
  
 REDEMPTION OF SECURITIES 
  
 Section 11.1. Applicability of This Article. 
  
 Redemption of Securities of any series (whether by operation of a sinking fund or otherwise) as permitted or required by any form of Security issued pursuant to this Indenture shall be made in accordance with such
form of Security and this Article; provided, however, that if any provision of any such form of Security shall conflict with any provision of this Article, the provision of such form of Security shall govern. Except as otherwise set forth in
the form of Security for such series, each Security of a series shall be subject to partial redemption only in the amount of $1,000 or any integral multiples thereof. 
  
 Section 11.2. Election to Redeem; Notice to Trustee. 
  
 The election of the Corporation to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of
any redemption at the election of the Corporation, the Corporation shall, at least 45 days prior to the Redemption Date (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee and, in the case of Securities of a series
held by an Issuer Trust, the Property Trustee under the related Trust Agreement, of such date and of the principal amount of Securities of the applicable series to be redeemed and provide the additional information required to be included in the
notice or notices contemplated by Section 11.4; provided that in the case of any series of Securities initially issued to an Issuer Trust, for so long as such Securities are held by such Issuer Trust, such notice shall be given not less than
30 nor more than 75 days prior to such Redemption Date (unless a shorter notice shall be satisfactory to the Property Trustee under the related Trust Agreement). In the case of any redemption of Securities prior to the expiration of any restriction
on such redemption provided in the terms of such Securities, the Corporation shall furnish the Trustee with an Officers’ Certificate and an Opinion of Counsel evidencing compliance with such restriction. 
  

 -70- 

 Section 11.3. Selection of Securities to be Redeemed. 
  
 If less than all the Securities of any series are to be redeemed, the
particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of a portion of the principal amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an
authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. 
  
 The Trustee shall promptly notify the Corporation in writing of the Securities selected for partial redemption and the principal amount thereof to be
redeemed. For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Security redeemed or to be redeemed only in part, to the portion of the
principal amount of such Security that has been or is to be redeemed. 
  
 Section 11.4. Notice of Redemption. 
  
 Notice of
redemption shall be given by first-class mail, postage prepaid, mailed not later than the thirtieth day, and not earlier than the sixtieth day, prior to the Redemption Date, to each Holder of Securities to be redeemed, at the address of such Holder
as it appears in the Securities Register, provided that in the case of any series of Securities initially issued to an Issuer Trust, for so long as such Securities are held by such Issuer Trust, such notice shall be given not less than 45 nor
more than 75 days prior to such Redemption Date (unless a shorter notice shall be satisfactory to the Property Trustee under the related Trust Agreement). 
  
 With respect to Securities of each series to be redeemed, each notice of redemption shall provide the CUSIP number, if any, of the Securities to be
redeemed and shall state: 
  
 (a) the Redemption
Date; 
  
 (b) the Redemption Price or, if the
Redemption Price cannot be calculated prior to the time the notice is required to be sent, the estimate of the Redemption Price together with a statement that it is an estimate and that the actual Redemption Price will be calculated on the third
Business Day prior to the Redemption Date (and if an estimate is provided, a further notice shall be sent of the actual Redemption Price on the date that such Redemption Price is calculated); 
  
 (c) if less than all Outstanding Securities of such
particular series are to be redeemed, the identification (and, in the case of partial redemption, the respective principal amounts) of the particular Securities to be redeemed; 
  
 (d) that on the Redemption Date, the Redemption Price will become due and payable upon each such Security or
portion thereof, and that interest (including any Additional Interest) thereon, if any, shall cease to accrue on and after said date; 
  

 -71- 

 (e) the place or places where such Securities are to be surrendered for payment of the
Redemption Price; 
  
 (f) that the redemption is
for a sinking fund, if such is the case; 
  
 (g)
such other provisions as may be required in respect of the terms of a particular series of Securities. 
  
 Notice of redemption of Securities to be redeemed at the election of the Corporation shall be given by the Corporation or, at the Corporation’s
request, by the Trustee in the name and at the expense of the Corporation and shall be irrevocable. The notice if mailed in the manner provided above shall be conclusively presumed to have been duly given, whether or not the Holder receives such
notice. In any case, a failure to give such notice by mail or any defect in the notice to the Holder of any Security designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other
Security. 
  
 Section 11.5. Deposit of Redemption Price.

  
 Prior to 10:00 a.m., New York City time, on the Redemption
Date specified in the notice of redemption given as provided in Section 11.4, the Corporation will deposit with the Trustee or with one or more Paying Agents (or if the Corporation is acting as its own Paying Agent, the Corporation will segregate
and hold in trust as provided in Section 10.3) an amount of money sufficient to pay the Redemption Price of, and any accrued interest (including any Additional Interest) on, all the Securities (or portions thereof) that are to be redeemed on that
date. 
  
 Section 11.6. Payment of Securities Called for
Redemption. 
  
 If any notice of redemption has been given as
provided in Section 11.4, the Securities or portion of Securities with respect to which such notice has been given shall become due and payable on the date and at the place or places stated in such notice at the applicable Redemption Price, together
with accrued interest (including any Additional Interest) to the Redemption Date. On presentation and surrender of such Securities at a Place of Payment in said notice specified, the said Securities or the specified portions thereof shall be paid
and redeemed by the Corporation at the applicable Redemption Price, together with accrued interest (including any Additional Interest) to the Redemption Date; provided, however, that, unless otherwise specified as contemplated by Section 3.1,
installments of interest (including any Additional Interest) whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of
business on the relevant record dates according to their terms and the provisions of Section 3.8. 
  
 Upon presentation of any Security redeemed in part only, the Corporation shall execute and the Trustee shall authenticate and deliver to the Holder
thereof, at the expense of the Corporation, a new Security or Securities of the same series, of authorized denominations, in aggregate principal amount equal to the unredeemed portion of the Security so presented and having the same Original Issue
Date, Stated Maturity and terms. 
  

 -72- 

 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the
principal of and premium, if any, on such Security shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 
  
 Section 11.7. Right of Redemption of Securities Initially Issued to an Issuer Trust. 
  
 In the case of the Securities of a series initially issued to an Issuer Trust, except as otherwise specified as contemplated
by Section 3.1, the Corporation, at its option, may redeem such Securities (i) on or after the date specified in such Security, in whole at any time or in part from time to time, or (ii) upon the occurrence and during the continuation of a Tax Event
or a Capital Treatment Event, at any time within 90 days following the occurrence and during the continuation of such Tax Event or Capital Treatment Event, in whole (but not in part), in each case at a Redemption Price specified in such Security,
together with accrued interest (including any Additional Interest) to, but excluding, the Redemption Date. 
  
 If less than all the Securities of any such series are to be redeemed, the aggregate principal amount of such Securities remaining Outstanding after
giving effect to such redemption shall be sufficient to satisfy any provisions of the Trust Agreement related to the Issuer Trust to which such Securities were issued, including any requirement in such Trust Agreement as to the minimum Liquidation
Amount (as defined in such Trust Agreement) of Capital Securities that may be held by a holder of Capital Securities thereunder. 
  
 ARTICLE XII 
  
 SINKING FUNDS 
  
 Section 12.1. Applicability of Article. 
  
 The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any series except as otherwise specified as
contemplated by Section 3.1 for such Securities. 
  
 The minimum
amount of any sinking fund payment provided for by the terms of any Securities of any series is herein referred to as a “mandatory sinking fund payment”, and any sinking fund payment in excess of such minimum amount that is permitted to be
made by the terms of such Securities of any series is herein referred to as an “optional sinking fund payment”. If provided for by the terms of any Securities of any series, the cash amount of any sinking fund payment may be subject to
reduction as provided in Section 12.2. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the terms of such Securities. 
  
 Section 12.2. Satisfaction of Sinking Fund Payments with Securities. 
  
 In lieu of making all or any part of a mandatory sinking fund payment with
respect to any Securities of a series in cash, the Corporation may at its option, at any time no more than 16 months and no less than 45 days prior to the date on which such sinking fund payment is due, deliver to the Trustee Securities of such
series (together with the unmatured coupons, if any, appertaining thereto) theretofore purchased or otherwise acquired by the Corporation, 

  

 -73- 

 
except Securities of such series that have been redeemed through the application of mandatory or optional sinking fund payments pursuant to the terms of the
Securities of such series, accompanied by a Corporation Order instructing the Trustee to credit such obligations and stating that the Securities of such series were originally issued by the Corporation by way of bona fide sale or other negotiation
for value; provided that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and credited for such purpose by the Trustee at the redemption price for such Securities, as
specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 
  
 Section 12.3. Redemption of Securities for Sinking Fund. 
  
 Not less than 45 days prior to each sinking fund payment date for any series
of Securities, the Corporation will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, the portion thereof, if any, which
is to be satisfied by payment of cash in the currency in which the Securities of such series are payable (except as provided pursuant to Section 3.1) and the portion thereof, if any, that is to be satisfied by delivering and crediting Securities
pursuant to Section 12.2 and will also deliver to the Trustee any Securities to be so delivered. Such Officers’ Certificate shall be irrevocable and upon its delivery the Corporation shall be obligated to make the cash payment or payments
therein referred to, if any, on or before the succeeding sinking fund payment date. In the case of the failure of the Corporation to deliver such Officers’ Certificate (or, as required by this Indenture, the Securities and coupons, if any,
specified in such Officers’ Certificate) by the due date therefor, the sinking fund payment due on the succeeding sinking fund payment date for such series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of
the Securities of such series subject to a mandatory sinking fund payment without the right to deliver or credit securities as provided in Section 12.2 and without the right to make the optional sinking fund payment with respect to such series at
such time. 
  
 Any sinking fund payment or payments (mandatory or
optional) made in cash plus any unused balance of any preceding sinking fund payments made with respect to the Securities of any particular series shall be applied by the Trustee (or by the Corporation if the Corporation is acting as its own Paying
Agent) on the sinking fund payment date on which such payment is made (or, if such payment is made before a sinking fund payment date, on the sinking fund payment date immediately following the date of such payment) to the redemption of Securities
of such series at the Redemption Price specified in such Securities with respect to the sinking fund. Any sinking fund moneys not so applied or allocated by the Trustee (or, if the Corporation is acting as its own Paying Agent, segregated and held
in trust by the Corporation as provided in Section 10.3) for such series and together with such payment (or such amount so segregated) shall be applied in accordance with the provisions of this Section 12.3. Any and all sinking fund moneys with
respect to the Securities of any particular series held by the Trustee (or if the Corporation is acting as its own Paying Agent, segregated and held in trust as provided in Section 10.3) on the last sinking fund payment date with respect to
Securities of such series and not held for the payment or redemption of particular Securities of such series shall be applied by the Trustee (or by the Corporation if the Corporation is acting as its own Paying Agent), together with other moneys, if
necessary, 

  

 -74- 

 
to be deposited (or segregated) sufficient for the purpose, to the payment of the principal of the Securities of such series at Maturity. The Trustee shall
select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.3 and cause notice of the redemption thereof to be given in the name of and at the expense of the Corporation in the manner provided in
Section 11.4. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Section 11.6. On or before each sinking fund payment date, the Corporation shall pay to the Trustee (or, if
the Corporation is acting as its own Paying Agent, the Corporation shall segregate and hold in trust as provided in Section 10.3) in cash a sum in the currency in which Securities of such series are payable (except as provided pursuant to Section
3.1) equal to the principal (and premium, if any) and any interest (including any Additional Interest) accrued to the Redemption Date for Securities or portions thereof to be redeemed on such sinking fund payment date pursuant to this Section 12.3.

  
 Neither the Trustee nor the Corporation shall redeem any
Securities of a series with sinking fund moneys or mail any notice of redemption of Securities of such series by operation of the sinking fund for such series during the continuance of a default in payment of interest, if any, on any Securities of
such series or of any Event of Default (other than an Event of Default occurring as a consequence of this paragraph) with respect to the Securities of such series, except that if the notice of redemption shall have been provided in accordance with
the provisions hereof, the Trustee (or the Corporation, if the Corporation is then acting as its own Paying Agent) shall redeem such Securities if cash sufficient for that purpose shall be deposited with the Trustee (or segregated by the
Corporation) for that purpose in accordance with the terms of this Article XII. Except as aforesaid, any moneys in the sinking fund for such series at the time when any such default or Event of Default shall occur and any moneys thereafter paid into
such sinking fund shall, during the continuance of such default or Event of Default, be held as security for the payment of the Securities and coupons, if any, of such series; provided however, that in case such default or Event of Default
shall have been cured or waived herein, such moneys shall thereafter be applied on the next sinking fund payment date for the Securities of such series on which such moneys may be applied pursuant to the provisions of this Section 12.3. 

 
 ARTICLE XIII 
  
 SUBORDINATION OF SECURITIES 
  
 Section 13.1. Securities Subordinate to Senior Indebtedness.

  
 The Corporation covenants and agrees, and each Holder of a
Security, by its acceptance thereof, likewise covenants and agrees, that, to the extent and in the manner hereinafter set forth in this Article, the payment of the principal of (and premium, if any) and interest (including any Additional Interest)
on each and all of the Securities of each and every series are hereby expressly made subordinate and subject in right of payment to the prior payment in full of all Senior Indebtedness. 
  

 -75- 

 Section 13.2. No Payment When Senior Indebtedness in Default; Payment Over of Proceeds Upon
Dissolution, Etc. 
  
 If the Corporation shall default in the
payment of any principal of (or premium, if any) or interest, if any, or any other amount payable on any Senior Indebtedness when the same becomes due and payable, whether at maturity or at a date fixed for prepayment or by declaration of
acceleration or otherwise, then, upon written notice of such default to the Corporation by the holders of Senior Indebtedness or any trustee therefor, unless and until such default shall have been cured or waived or shall have ceased to exist or all
Senior Indebtedness has been paid, no direct or indirect payment (in cash, property, securities, by set-off or otherwise) shall be made or agreed to be made on account of the principal of (or premium, if any) or interest (including any Additional
Interest) on any of the Securities, or in respect of any redemption, repayment, retirement, purchase or other acquisition of any of the Securities. 
  
 In the event of (a) any insolvency, bankruptcy, receivership, liquidation, reorganization, readjustment, composition or other similar proceedings relating
to the Corporation or its property, (b) any proceeding for the liquidation, dissolution or other winding up of the Corporation, voluntary or involuntary, whether or not involving insolvency or bankruptcy proceedings, (c) any assignment by the
Corporation for the benefit of creditors or (d) any other marshalling of the assets of the Corporation (each such event, if any, herein sometimes referred to as a “Proceeding”), all Senior Indebtedness (including any interest
thereon accruing after the commencement of any such proceedings) shall first be paid in full before any payment or distribution, whether in cash, securities or other property, shall be made to any Holder of any of the Securities on account thereof.
Any payment or distribution, whether in cash, securities or other property (other than securities of the Corporation or any other corporation provided for by a plan of reorganization or readjustment the payment of which is subordinate, at least to
the extent provided in these subordination provisions with respect to the indebtedness evidenced by the Securities, to the payment of all Senior Indebtedness at the time outstanding and to any securities issued in respect thereof under any such plan
of reorganization or readjustment), which would otherwise (but for these subordination provisions) be payable or deliverable in respect of the Securities of any series shall be paid or delivered directly to the holders of Senior Indebtedness in
accordance with the priorities then existing among such holders until all Senior Indebtedness (including any interest thereon accruing after the commencement of any Proceeding) shall have been paid in full. 
  
 In the event of any Proceeding, after payment in full of all sums owing with
respect to Senior Indebtedness, the Holders of the Securities, together with the holders of any obligations of the Corporation ranking on a parity with the Securities, shall be entitled to be paid from the remaining assets of the Corporation the
amounts at the time due and owing on account of unpaid principal of (and premium, if any) and interest on the Securities and such other obligations before any payment or other distribution, whether in cash, property or otherwise, shall be made on
account of any capital stock or any obligations of the Corporation ranking junior to the Securities and such other obligations. If, notwithstanding the foregoing, any payment or distribution of any character or any security, whether in cash,
securities or other property (other than securities of the Corporation or any other corporation 

  

 -76- 

 
provided for by a plan of reorganization or readjustment the payment of which is subordinate, at least to the extent provided in these subordination
provisions with respect to the indebtedness evidenced by the Securities, to the payment of all Senior Indebtedness at the time outstanding and to any securities issued in respect thereof under any such plan of reorganization or readjustment), shall
be received by the Trustee or any Holder in contravention of any of the terms hereof and before all Senior Indebtedness shall have been paid in full, such payment or distribution or security shall be received in trust for the benefit of, and shall
be paid over or delivered and transferred to, the holders of the Senior Indebtedness at the time outstanding in accordance with the priorities then existing among such holders for application to the payment of all Senior Indebtedness remaining
unpaid, to the extent necessary to pay all such Senior Indebtedness in full. In the event of the failure of the Trustee or any Holder to endorse or assign any such payment, distribution or security, each holder of Senior Indebtedness is hereby
irrevocably authorized to endorse or assign the same. 
  
 The
Trustee and the Holders shall take such action (including, without limitation, the delivery of this Indenture to an agent for the holders of Senior Indebtedness or consent to the filing of a financing statement with respect hereto) as may, in the
opinion of counsel designated by the holders of a majority in principal amount of the Senior Indebtedness at the time outstanding, be necessary or appropriate to assure the effectiveness of the subordination effected by these provisions. 

 
 The provisions of this Section 13.2 shall not impair any rights,
interests, remedies or powers of any secured creditor of the Corporation in respect of any security interest the creation of which is not prohibited by the provisions of this Indenture. 
  
 The securing of any obligations of the Corporation, otherwise ranking on a parity with the Securities or ranking junior to
the Securities, shall not be deemed to prevent such obligations from constituting, respectively, obligations ranking on a parity with the Securities or ranking junior to the Securities. 
  
 Section 13.3. Payment Permitted If No Default. 
  
 Nothing contained in this Article or elsewhere in this Indenture or in any of the Securities shall prevent (a) the
Corporation, at any time, except during the pendency of the conditions described in the first paragraph of Section 13.2 or of any Proceeding referred to in Section 13.2, from making payments at any time of principal of (and premium, if any) or
interest (including any Additional Interest) on the Securities, or (b) the application by the Trustee of any moneys deposited with it hereunder to the payment of or on account of the principal of (and premium, if any) or interest (including any
Additional Interest) on the Securities or the retention of such payment by the Holders, if, at the time of such application by the Trustee, it did not have knowledge that such payment would have been prohibited by the provisions of this Article.

  

 -77- 

 Section 13.4. Subrogation to Rights of Holders of Senior Indebtedness. 
  
 Subject to the payment in full of all amounts due or to become due on all
Senior Indebtedness, or the provision for such payment in cash or cash equivalents or otherwise in a manner satisfactory to the holders of Senior Indebtedness, the Holders of the Securities shall be subrogated to the extent of the payments or
distributions made to the holders of such Senior Indebtedness pursuant to the provisions of this Article (equally and ratably with the holders of all indebtedness of the Corporation that by its express terms is subordinated to Senior Indebtedness of
the Corporation to substantially the same extent as the Securities are subordinated to the Senior Indebtedness and is entitled to like rights of subrogation by reason of any payments or distributions made to holders of such Senior Indebtedness) 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 (and premium, if any) and interest (including any Additional
Interest) on the Securities 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 Securities or the Trustee
would be entitled except for the provisions of this Article, and no payments over pursuant to the provisions of this Article to the holders of Senior Indebtedness by Holders of the Securities or the Trustee, shall, as among the Corporation, its
creditors other than holders of Senior Indebtedness, and the Holders of the Securities, be deemed to be a payment or distribution by the Corporation to or on account of the Senior Indebtedness. 
  
 Section 13.5. Provisions Solely to Define Relative Rights. 

 
 The provisions of this Article are and are intended solely for the purpose
of defining the relative rights of the Holders of the Securities on the one hand and the holders of Senior Indebtedness on the other hand. Nothing contained in this Article or elsewhere in this Indenture or in the Securities is intended to or shall
(a) impair, as between the Corporation and the Holders of the Securities, the obligations of the Corporation, which are absolute and unconditional, to pay to the Holders of the Securities the principal of (and premium, if any) and interest
(including any Additional Interest) on the Securities as and when the same shall become due and payable in accordance with their terms; or (b) affect the relative rights against the Corporation of the Holders of the Securities and creditors of the
Corporation other than their rights in relation to the holders of Senior Indebtedness; or (c) prevent the Trustee or the Holder of any Security (or to the extent expressly provided herein, the holder of any Capital Security) from exercising all
remedies otherwise permitted by applicable law upon default under this Indenture, including filing and voting claims in any Proceeding, subject to the rights, if any, under this Article of the holders of Senior Indebtedness to receive cash, property
and securities otherwise payable or deliverable to the Trustee or such Holder. 
  
 Section 13.6. Trustee to Effectuate Subordination. 
  
 Each Holder of a Security by his or her acceptance thereof authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination
provided in this Article and appoints the Trustee his or her attorney-in-fact for any and all such purposes. 
  

 -78- 

 Section 13.7. No Waiver of Subordination Provisions. 
  
 No right of any present or future holder of any Senior Indebtedness to
enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Corporation or by any act or failure to act, in good faith, by any such holder, or by any noncompliance
by the Corporation with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof that any such holder may have or be otherwise charged with. 
  
 Without in any way limiting the generality of the immediately preceding paragraph, the holders of Senior Indebtedness may,
at any time and from to time, without the consent of or notice to the Trustee or the Holders of the Securities of any series, without incurring responsibility to such Holders of the Securities and without impairing or releasing the subordination
provided in this Article or the obligations hereunder of such Holders of the Securities to the holders of Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or
renew or alter, Senior Indebtedness, or otherwise amend or supplement in any manner Senior Indebtedness or any instrument evidencing the same or any agreement under which Senior Indebtedness is outstanding; (ii) sell, exchange, release or otherwise
deal with any property pledged, mortgaged or otherwise securing Senior Indebtedness; (iii) release any Person liable in any manner for the collection of Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the
Corporation and any other Person. 
  
 Section 13.8. Notice to
Trustee. 
  
 The Corporation shall give prompt written notice
to the Trustee of any fact known to the Corporation that would prohibit the making of any payment to or by the Trustee in respect of the Securities. Notwithstanding the provisions of this Article 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 Securities, unless and until the Trustee shall have received written notice thereof from the
Corporation or a holder of Senior Indebtedness or from any trustee, agent or representative therefor; provided however, that if the Trustee shall not have received the notice provided for in this Section at least three Business Days prior to
the date upon which by the terms hereof any monies may become payable for any purpose (including, the payment of the principal of (and premium, if any, on) or interest (including any Additional Interest) on any Security), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive such monies and to apply the same to the purpose for which they were received and shall not be affected by any notice to the contrary that may be
received by it within three Business Days prior to such date. 
  
 Subject to the provisions of Section 6.1, the Trustee shall be entitled to rely on the delivery to it of a written notice by a Person representing himself or herself to be a holder of Senior Indebtedness (or a trustee or attorney-in-fact
therefor) to establish that such notice has been given by a holder of Senior Indebtedness (or a trustee or attorney-in-fact therefor). In the event that 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 

  

 -79- 

 
payment or distribution pursuant to this Article, 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, 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. 
  
 Section 13.9. Reliance on Judicial Order or Certificate of Liquidating Agent. 
  
 Upon any payment or distribution of assets of the Corporation referred to in this Article, the Trustee, subject to the
provisions of Section 6.1, and the Holders of the Securities shall be entitled to rely upon any order or decree entered by any court of competent jurisdiction in which such Proceeding is pending, or a certificate of the trustee in bankruptcy,
receiver, liquidating trustee, custodian, assignee for the benefit of creditors, agent or other Person making such payment or distribution, delivered to the Trustee or to the Holders of Securities, 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 Corporation, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this Article. 
  
 Section 13.10.
Trustee Not Fiduciary for Holders of Senior Indebtedness. 
  
 The Trustee, in its capacity as trustee under this Indenture, shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if it shall in good faith mistakenly pay over or
distribute to Holders of Securities or to the Corporation or to any other Person cash, property or securities to which any holders of Senior Indebtedness shall be entitled by virtue of this Article or otherwise. 
  
 Section 13.11. Rights of Trustee as Holder of Senior Indebtedness;
Preservation of Trustee’s Rights.

	 	Re:	[Title of Securities] of Cullen/Frost Bankers, Inc. (the “Securities”) 

  
 Reference is made to the Junior Subordinated Indenture, dated as of February 13, 2004 (the “Indenture”),
between Cullen/Frost Bankers, Inc., a Texas corporation, and The Bank of New York, a New York banking corporation, as Trustee. Terms used herein and defined in the Indenture or in Rule 144A, Regulation D, Regulation S or Rule 144 under the United
States Securities Act of 1933 (the “Securities Act”) are used herein as so defined. 
  
 This certificate relates to
$                     aggregate principal amount of Securities, which are evidenced by the following certificate(s) (the “Specified
Securities”): 
  
 CUSIP No(s).
                                        
         
 CERTIFICATE No(s).
                                        

 CURRENTLY IN BOOK-ENTRY FORM: Yes                 
No                  (check one) 
  
 The person in whose name this certificate is executed below (the “Undersigned”) hereby certifies that either (i) it is the sole
beneficial owner of the Specified Securities or (ii) it is acting on behalf of all the beneficial owners of the Specified Securities and is duly authorized by them to do so. Such beneficial owner or owners are referred to herein collectively as the
“Owner”. If the Specified Securities are represented by a Global Security, they are held through a Depositary (except in the name of the “The Depository Trust Company”) or an Agent Member in the name of the Undersigned, as
or on behalf of the Owner. If the Specified Securities are not represented by a Global Security, they are registered in the name of the Undersigned, as or on behalf of the Owner. 
  
 The Owner has requested that the Specified Securities be transferred to a person (the “Transferee”) who
will take delivery in the form of a Restricted Security. In connection with such transfer, the Owner hereby certifies that, unless such transfer is being effected pursuant to an effective registration statement under the Securities Act, it is being
effected as set forth below in accordance with all applicable securities laws of the United States, the states of the United States and other jurisdictions. Accordingly, the Owner hereby certifies: 
  
 (1) Rule 144A Transfers. If the transfer is being
effected in accordance with Rule 144A: 
  
 (A)
the Specified Securities are being transferred to a person that the Owner and any person acting on its behalf reasonably believe is a “qualified institutional buyer” within the meaning of Rule 144A, acquiring for its own
account or for the account of a qualified institutional buyer; and 
  

 A-1 

 (B) the Owner and any person acting on its behalf have taken reasonable steps to ensure
that the Transferee is aware that the Owner may be relying on Rule 144A in connection with the transfer; and 
  
 (2) Institutional Accredited Investor Transfers. If the transfer is being effected to a Transferee that is an “institutional
accredited investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) of Regulation D under the Securities Act that is not a “qualified institutional buyer” within the meaning of Rule 144A, the Transferee shall have furnished to
the Corporation and the Securities Registrar a duly executed Institutional Accredited Investor Letter and such other certifications, legal opinions or other information as they or either of them may reasonably require to confirm that such transfer
is being made pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act. An “institutional accredited investor’ may not hold the specified securities or an interest therein in
book-entry form or in any other form intended to facilitate book-entry trading in beneficial interests in such securities. 
  
 (3) Rule 904 Transfers. If the transfer is being effected in accordance with Rule 904: 
  
 (A) the Owner is not a distributor of the Securities, an
affiliate of the Corporation or any such distributor or a person acting in behalf of any of the foregoing; 
  
 (B) the offer of the Specified Securities was not made to a person in the United States; 
  
 (C) either: 
  
 (i) at the time the buy order was originated, the Transferee was outside
the United States or the Owner and any person acting on its behalf reasonably believed that the Transferee was outside the United States, or 
  
 (ii) the transaction is being executed in, on or through the facilities of the Eurobond market, as regulated by the Association of International Bond
Dealers, or another designated offshore securities market and neither the Owner nor any person acting on its behalf knows that the transaction has been prearranged with a buyer in the United States; 
  

 A-2 

 (D) no directed selling efforts have been made in the United States by or on behalf of
the Owner or any affiliate thereof; and 
  
 (E)
the transaction is not part of a plan or scheme to evade the registration requirements of the Securities act. 
  
 (4) Rule 144 Transfers. If the transfer is being effected pursuant to Rule 144: 
  
 (A) the transfer is occurring after a holding period of at
least one year (computed in accordance with paragraph (d) of Rule 144) has elapsed since the date the Specified Securities were acquired from the Corporation or from an affiliate (as such term is defined in Rule 144) of the Corporation, whichever is
later, and is being effected in accordance with the applicable amount, manner of sale and notice requirements of paragraphs (e), (f) and (h) of Rule 144; or 
  
 (B) the transfer is occurring after a holding period by the Owner of at least two years has elapsed since the date the Specified
Securities were acquired from the Corporation or from an affiliate (as such term is defined in Rule 144) of the Corporation, whichever is later, and the Owner is not, and during the preceding three months has not been, an affiliate of the
Corporation. 
  
 This certificate and the statements contained
herein are made for your benefit and the benefit of the Corporation and the “Initial Purchaser” (as defined in the Trust Agreement relating to the Issuer Trust to which the Securities were initially issued).

one or more trusts, each of which is an “accredited investor” within the meaning of Rule 501(a)(7) under the Securities Act and for each of which we exercise sole investment discretion; if we are purchasing for the accounts of their

	 	•	in the event that we purchase any of the Securities, we will acquire Securities having a minimum principal amount of not less than $100,000 for our own account or for any separate

the Securities. 

  
 We understand that the
Securities are being offered in a transaction not involving any public offering within the United States within the meaning of the Securities Act and that the Securities have not been and will not be registered under the Securities Act, and we
agree, on our own behalf and on behalf of each account for which we acquire any Securities, that if in the future we decided to resell, pledge or otherwise transfer such Securities, such Securities may be offered, resold, pledged or otherwise
