 INDENTURE 

This INDENTURE dated as of March 31, 2022 is between Third Coast Bancshares, Inc., a Texas corporation and registered bank holding
company (the “Company”), and UMB Bank, National Association, a national banking association, as trustee (the “Trustee”). 

RECITALS 
 WHEREAS,
the Company has duly authorized the execution and delivery of this Indenture to provide for an issue of $82,250,000 in aggregate principal amount of 5.500%
Fixed-to-Floating Rate Subordinated Notes due 2032, subject to the terms and conditions set forth in this Indenture. 

NOW, THEREFORE, in order to declare the terms and conditions upon which the Subordinated Notes are authenticated, issued and delivered, and in
consideration of the premises, and of the purchase and acceptance of the Subordinated Notes by the Holders thereof, the Company and the Trustee agree as follows for the benefit of each other and for the benefit of the respective Holders from time to
time of the Subordinated Notes. 
 ARTICLE I 

DEFINITIONS AND INCORPORATION BY REFERENCE 

1.01 Definitions. 

Except as otherwise expressly provided in this Indenture or unless the context otherwise requires, the terms defined in this Section for all
purposes of this Indenture, any Company Order, any Board Resolution, and any indenture supplemental hereto will have the respective meanings specified in this Section. 

“Act,” when used with respect to any Holders, is defined in Section 1.04. 

“Additional Interest” has the meaning set forth in the Registration Rights Agreement. 

“Affiliate” means, with respect to any specified Person, any other Person directly or indirectly controlling or
controlled by or under direct or indirect common control with such specified Person. For the purposes of this definition, “control,” when used with respect to any specified Person means the power to direct the management and policies of
such Person, directly or indirectly, whether through the ownership of voting securities, by contract or otherwise; and the terms “controlling” and “controlled” have meanings correlative to the foregoing. 

“Applicable Procedures” means, with respect to any transfer or exchange of or for beneficial interests in any Global
Subordinated Note, the rules and procedures of the Depositary that apply to such transfer or exchange. 
 “Authenticating
Agent” means any Person authorized by the Trustee in accordance with Section 5.12 to act on behalf of the Trustee to authenticate Subordinated Notes. 











 “Authorized Officer” means each of the Chairman of the Board, the
Chief Executive Officer, the President, any Senior Executive Vice President and the Chief Financial Officer of the Company. 

“Bankruptcy Laws” mean Title 11, United States Code (11 U.S.C. §§101 et seq.) or any similar federal or
state law for the relief of debtors. 
 “Benchmark” means, initially, Three-Month Term SOFR; provided that if the
Calculation Agent determines on or prior to the Reference Time for any Floating Rate Period that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR or the then-current
Benchmark, then “Benchmark” means the applicable Benchmark Replacement for such Floating Rate Period and any subsequent Floating Rate Periods. 

“Benchmark Replacement” means the Interpolated Benchmark with respect to the then-current Benchmark, plus the
Benchmark Replacement Adjustment for such Benchmark; provided that if (a) the Calculation Agent cannot determine the Interpolated Benchmark as of the Benchmark Replacement Date or (b) the then-current Benchmark is Three-Month Term SOFR and
a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR (in which event no Interpolated Benchmark with respect to Three-Month Term SOFR shall be determined), then
“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Calculation Agent in its reasonable discretion as of the Benchmark Replacement Date: 

 

	 	(1)	 Compounded SOFR; 


  

	 	(2)	 the sum of: (i) the alternate rate that has been selected or recommended by the Relevant Governmental Body
as the replacement for the then-current Benchmark for the applicable Corresponding Tenor and (ii) the Benchmark Replacement Adjustment; 


  

	 	(3)	 the sum of: (i) the ISDA Fallback Rate and (ii) the Benchmark Replacement Adjustment; or



  

	 	(4)	 the sum of: (i) the alternate rate that has been selected by the Calculation Agent as the replacement for
the then-current Benchmark for the applicable Corresponding Tenor, giving due consideration to any industry-accepted rate as a replacement for the then-current Benchmark for U.S. Dollar-denominated floating rate securities at such time, and
(ii) the Benchmark Replacement Adjustment. 


 “Benchmark Replacement Adjustment” means the
first alternative set forth in the order below that can be determined by the Calculation Agent in its reasonable discretion, as of the Benchmark Replacement Date: 
  

	 	(1)	 the spread adjustment, or method for calculating or determining such spread adjustment (which may be a positive
or negative value or zero), that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement; 



  
 2 













	 	(2)	 if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, then the ISDA
Fallback Adjustment; or 


  

	 	(3)	 the spread adjustment (which may be a positive or negative value or zero) that has been selected by the
Calculation Agent giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark
Replacement for U.S. Dollar-denominated floating rate securities at such time. 


 “Benchmark Replacement
Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of “Floating Rate Period,” timing and frequency of determining
rates with respect to each Floating Rate Period and making payments of interest, rounding of amounts or tenors, and other administrative matters) that the Calculation Agent in its reasonable discretion determines may be appropriate to reflect the
adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Calculation Agent determines that adoption of any portion of such market practice is not administratively feasible or if the Calculation
Agent determines that no market practice for use of the Benchmark Replacement exists, in such other manner as the Calculation Agent determines is reasonably necessary). 

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current
Benchmark: 
  

	 	(1)	 in the case of clause (1) of the definition of “Benchmark Transition Event,” the relevant
Reference Time in respect of any determination; 


  

	 	(2)	 in the case of clause (2) or (3) of the definition of “Benchmark Transition Event,” the later of
(i) the date of the public statement or publication of information referenced therein and (ii) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark; or 



 

	 	(3)	 in the case of clause (4) of the definition of “Benchmark Transition Event,” the date of the
public statement or publication of information referenced therein. 


 For the avoidance of doubt, for purposes of the definitions of
Benchmark Replacement Date and Benchmark Transition Event, references to the Benchmark also include any reference rate underlying the Benchmark (for example, if the Benchmark becomes Compounded SOFR, references to the Benchmark would include SOFR).

 For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in
respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination. 

  
 3 












 “Benchmark Transition Event” means the occurrence of one or more of
the following events with respect to the then-current Benchmark: 
  

	 	(1)	 if the Benchmark is Three-Month Term SOFR, (i) the Relevant Governmental Body has not selected or
recommended a forward-looking term rate for a tenor of three months based on SOFR, (ii) the development of a forward-looking term rate for a tenor of three months based on SOFR that has been recommended or selected by the Relevant Governmental
Body is not complete or (iii) the Calculation Agent determines that the use of a forward-looking rate for a tenor of three months based on SOFR is not administratively feasible; 



 

	 	(2)	 a public statement or publication of information by or on behalf of the administrator of the Benchmark
announcing that such administrator has ceased or will cease to provide the Benchmark, permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the
Benchmark; 


  

	 	(3)	 a public statement or publication of information by the regulatory supervisor for the administrator of the
Benchmark, the central bank for the currency of the Benchmark, an insolvency official with jurisdiction over the administrator for the Benchmark, a resolution authority with jurisdiction over the administrator for the Benchmark or a court or an
entity with similar insolvency or resolution authority over the administrator for the Benchmark, which states that the administrator of the Benchmark has ceased or will cease to provide the Benchmark permanently or indefinitely, provided that, at
the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark; or 


  

	 	(4)	 a public statement or publication of information by the regulatory supervisor for the administrator of the
Benchmark announcing that the Benchmark is no longer representative.

Governmental Body for determining Compounded SOFR; provided that: 


  

	 	(2)	 if, and to the extent that, the Calculation Agent determines that Compounded SOFR cannot be determined in
accordance with clause (a) above, then the rate, or methodology for this rate, and conventions for this rate that have been selected by the Calculation Agent giving due consideration to any industry-accepted market practice for U.S.
Dollar-denominated floating rate securities at such time.

action taken in reliance upon such waiver. 
 Notwithstanding any other provision herein, where this Indenture provides for notice to any
Holder of a Global Subordinated Note, or of an interest therein, such notice will be sufficiently given if given to the Depositary for such Global Subordinated Note (or its designee) according to the Applicable Procedures of such Depositary

Trust Indenture Act that may be so modified or excluded, the provisions of the Trust Indenture Act will be deemed to apply to this Indenture as so modified or will be excluded, as the case may be.

 THE
SUBORDINATED NOTES 
 2.01 Forms Generally. 

The Subordinated Notes and the Trustee’s certificate of authentication will be substantially in the form of Exhibit A-1 and Exhibit A-2, as applicable, which are a part of this Indenture. The Subordinated Notes may have notations, legends or endorsements required by law, stock
exchange rule or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Company). The Company will provide any such notations, legends or endorsements to the Trustee in writing. Each Subordinated Note will be
dated the date of its authentication. The terms and provisions contained in the Subordinated Notes will constitute, and are hereby expressly made a part of this Indenture and the Company and the Trustee, by their execution and delivery of this
Indenture, agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Subordinated Note irreconcilably conflicts with the express provisions of this Indenture, the provisions of this Indenture will govern
and be controlling. 

  
 20 












 2.02 Definitive Subordinated Notes. 

The Initial Notes will be issued initially in the form of one or more Definitive Subordinated Notes, unless, before the issuance of such
Initial Notes, the Company has determined that the Initial Notes may be represented by Global Subordinated Notes and has so notified the Trustee, in which event the Initial Notes will be issued in the form of one or more Global Subordinated Notes.
The Exchange Notes will also be issued initially in the form of one or more Definitive Subordinated Notes, unless, before the issuance of such Exchange Notes, the Company has determined that the Subordinated Notes may be represented by Global
Subordinated Notes and has so notified the Trustee, in which event the Exchange Notes will be issued in the form of one or more Global Subordinated Notes. Except as provided in Section 2.07, Holders of Definitive Subordinated Notes will not be
entitled to transfer Definitive Subordinated Notes in exchange for beneficial interests in Global Subordinated Notes, and owners of beneficial interests in Global Subordinated Notes will not be entitled to receive physical delivery of Definitive
Subordinated Notes. 
 2.03 Global Subordinated Notes. 

Each Global Subordinated Note issued under this Indenture will be deposited with the Trustee at its Corporate Trust Office, as custodian for
the Depositary, and registered in the name of the Depositary or the nominee thereof, duly executed by the Company and authenticated by the Trustee as hereinafter provided. The aggregate principal amount of any Global Subordinated Note may from time
to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary as hereinafter provided. Any adjustment of the aggregate principal amount of a Global Subordinated Note to reflect the amount of any increase or
decrease in the amount of outstanding Subordinated Notes represented thereby will be made by the Trustee in accordance with instructions given by the Holder thereof as required by Section 2.07 hereof and will be made on the records of the
Trustee and the Depositary. 
 2.04 Restricted Subordinated Notes. 

Each Restricted Subordinated Note will bear a legend in substantially the following form: 

“THE SECURITIES REPRESENTED BY THIS INSTRUMENT HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT BE TRANSFERRED, SOLD OR OTHERWISE DISPOSED OF EXCEPT (A) PURSUANT TO, AND IN ACCORDANCE WITH, A REGISTRATION STATEMENT THAT IS EFFECTIVE UNDER THE SECURITIES ACT AT
THE TIME OF SUCH TRANSFER; (B) TO A PERSON THAT YOU REASONABLY BELIEVE TO BE A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT; OR (C) UNDER ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT (INCLUDING, IF AVAILABLE, THE EXEMPTION PROVIDED BY RULE 144 UNDER THE SECURITIES ACT), AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS, AS EVIDENCED BY A LEGAL OPINION OF COUNSEL IN FORM
AND SUBSTANCE REASONABLY SATISFACTORY TO THE COMPANY TO THE EFFECT THAT REGISTRATION IS NOT REQUIRED.” 

  
 21 












 The Private Placement Legend set forth above will be removed and a new Subordinated Note of
like tenor and principal amount without such Private Placement Legend will be executed by the Company, and upon written request of the Company (together with an Officers’ Certificate and an Opinion of Counsel) given at least three Business Days
prior to the proposed authentication date, the Trustee will authenticate and deliver such new Subordinated Note to the respective Holder, in each case if legal counsel to the Holder or owner of beneficial interests requesting the removal of such
Private Placement Legend delivers to the Trustee, any Registrar and Paying Agent (if a different Person than the Trustee) and the Company an opinion of counsel in compliance with this Indenture and additionally opining that the restrictive legend
can be removed in connection with the transfer in accordance with the Securities Act. 
 2.05 Execution and Authentication. 

Subordinated Notes will be executed on behalf of the Company by any Authorized Officer and may (but need not) have the Company’s
corporate seal or a facsimile thereof reproduced thereon. The signature of an Authorized Officer on the Subordinated Notes may be manual or facsimile. Subordinated Notes bearing the manual or facsimile signatures of individuals who were at the time
of execution Authorized Officers of the Company will, to the fullest extent permitted by law, bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such
Subordinated Notes or did not hold such offices at the date of such Subordinated Notes. 
 The Trustee or an Authenticating Agent will
authenticate and deliver the Initial Notes for original issue in an aggregate principal amount of up to $82,250,000 upon one or more Company Orders and an Opinion of Counsel. In addition, the Trustee or an Authenticating Agent will upon receipt of a
Company Order, Opinion of Counsel and Officers’ Certificate authenticate and deliver any Exchange Notes for an aggregate principal amount not to exceed $82,250,000 specified in such Company Order for Exchange Notes issued hereunder. The
aggregate principal amount of Outstanding Subordinated Notes to be issued hereunder may be increased at any time hereafter and the series may be reopened for issuances of additional Subordinated Notes upon Company Order without the consent of any
Holder. The Subordinated Notes issued on the date hereof and any such additional Subordinated Notes that may be issued hereafter shall be part of the same series of Subordinated Notes for all purposes under the Indenture. Unless the context
otherwise requires, the initial Subordinated Notes and the Exchange Notes shall constitute one series for all purposes under the Indenture, including with respect to any amendment, waiver, acceleration or other Act of the Holders or upon redemption
of the Subordinated Notes. The Subordinated Notes will be issued only in registered form without coupons and in minimum denominations of $100,000 and any integral multiple of $1,000 in excess thereof. 

The Trustee will not be required to authenticate any Subordinated Notes if the issue of such Subordinated Notes under this Indenture will
affect the Trustee’s own rights, duties or immunities under the Subordinated Notes and this Indenture or otherwise in a manner that is not reasonably acceptable to the Trustee or if the Trustee, being advised by counsel, determines that such
action may not lawfully be taken. 

  
 22 












 No Subordinated Note will be entitled to any benefit under this Indenture or be valid or
obligatory for any purpose, unless there appears on such Subordinated Note a certificate of authentication substantially in the form provided for herein executed by or on behalf of the Trustee or by the Authenticating Agent by the manual signature
of one of its authorized signatories. Such certificate upon any Subordinated Note will be conclusive evidence, and the only evidence, that such Subordinated Note has been duly authenticated and delivered hereunder. 

2.06 Registrar and Paying Agent. 

The Company will maintain an office or agency where Subordinated Notes may be presented for registration of transfer or for exchange
(“Registrar”) and an office or agency where Subordinated Notes may be presented for payment (“Paying Agent”). The Registrar will keep a register of the Subordinated Notes (“Subordinated Note
Register”) and of their transfer and exchange. The registered Holder of a Subordinated Note will be treated as the owner of the Subordinated Note for all purposes. The Company may appoint one or more
co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any
additional paying agent. The Company may change any Paying Agent or Registrar without prior notice to any Holder; provided that no such removal or replacement will be effective until a successor Paying Agent or Registrar will have been appointed by
the Company and will have accepted such appointment. The Company will notify the Trustee in writing of the name and address of any Registrar or Paying Agent not a party to this Indenture. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee will act as such. The Company or any of its Subsidiaries may act as Paying Agent or Registrar. 
 The
Company initially appoints the Trustee to act as the Paying Agent and Registrar for the Subordinated Notes and, in the event that any Subordinated Notes are issued in global form, to initially act as custodian with respect to the Global Subordinated
Notes. In the event that the Trustee will not be or will cease to be Registrar with respect the Subordinated Notes, it will have the right to examine the Subordinated Note Register at all reasonable times. There will be only one Subordinated Note
Register. 
 2.07 Registration of Transfer and Exchange 

(1) Except as otherwise provided in or under this Indenture, upon surrender for registration of transfer of any Subordinated Note, the Company
will execute, and the Trustee will, upon receipt of a Company Order, authenticate and deliver, in the name of the designated transferee or transferees, one or more new Subordinated Notes denominated as authorized in or under this Indenture, of a
like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions. 
 Except
as otherwise provided in or under this Indenture, at the option of the Holder, Subordinated Notes may be exchanged for other Subordinated Notes containing identical terms and provisions, in any authorized denominations (minimum denominations of
$100,000 and any integral multiple of $1,000 in excess thereof), and of a like aggregate principal amount, upon surrender of the Subordinated Notes to be exchanged at any office or agency for such purpose. Whenever any Subordinated Notes are so
surrendered for exchange, the Company will execute, and the Trustee will authenticate and deliver, subject to the terms hereof, the Subordinated Notes that the Holder making the exchange is entitled to receive. 

  
 23 












 All Subordinated Notes issued upon any registration of transfer or exchange of Subordinated
Notes will be the valid obligations of the Company evidencing the same debt and entitling the Holders thereof to the same benefits under this Indenture as the Subordinated Notes surrendered upon such registration of transfer or exchange. 

Every Subordinated Note presented or surrendered for registration of transfer or for exchange or redemption will (if so required by the
Company or the Registrar for such Subordinated Note) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar for such Subordinated Note duly executed by the Holder thereof or his
attorney duly authorized in writing. 
 No service charge will be made for any registration of transfer or exchange of Subordinated Notes,
or any redemption or repayment of Subordinated Notes, or any conversion or exchange of Subordinated Notes for other types of securities or property, but the Company may require payment of a sum sufficient to pay all taxes, assessments or other
governmental charges that may be imposed in connection with the transfer or exchange of the Subordinated Notes from the Holder requesting such transfer or exchange. 

Except as otherwise provided in or under this Indenture, the Company will not be required (i) to issue, register the transfer of or
exchange any Subordinated Notes during a period beginning at the opening of business 15 days before the day of the selection for redemption of Subordinated Notes under Section 10.03 and ending at the close of business on the day of such
selection, or (ii) to register the transfer of or exchange any Subordinated Note, or portion thereof, so selected for redemption, except in the case of any Subordinated Note to be redeemed in part, the portion thereof not to be redeemed. 

Any Registrar (if not the Trustee) appointed in accordance with Section 2.06 hereof will provide to the Trustee such information as the
Trustee may reasonably require in connection with the delivery by such Registrar of Subordinated Notes upon transfer or exchange of Subordinated Notes. No Registrar will be required to make registrations of transfer or exchange of Subordinated Notes
during any periods designated in the Subordinated Notes or in this Indenture as periods during which such registration of transfers and exchanges need not be made. 

The Trustee and the Registrar will have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on
transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Subordinated Note (including any transfers between or among Depositary participants or beneficial owners of interests in any Global
Subordinated Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture. 

Neither the Trustee nor any Paying Agent will have any responsibility for any actions taken or not taken by the Depositary. 

  
 24 












 (2) When Definitive Subordinated Notes are presented by a Holder to the Registrar with a
request to register the transfer of such Definitive Subordinated Notes or to exchange such Definitive Subordinated Notes for an equal principal amount of Definitive Subordinated Notes of other authorized denominations, the Registrar will register
the transfer or make the exchange as requested if its reasonable requirements for such transaction are met; provided, however, that the Definitive Subordinated Notes surrendered for transfer or exchange will be duly endorsed or accompanied by a
written instrument of transfer in form reasonably satisfactory to the Company and the Registrar, duly executed by the Holder thereof or such Holder’s attorney duly authorized in writing. 

(3) A Global Subordinated Note may not be transferred except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary
to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary. All Global Subordinated Notes will be exchanged by the Company for Definitive
Subordinated Notes if: (i) the Depositary has notified the Company that it is unwilling or unable to continue as Depositary for such Global Subordinated Note or such Depositary has ceased to be a “clearing agency” registered under the
Exchange Act, and a successor depositary is not appointed by the Company within 90 days, (ii) the Company determines that the Subordinated Notes are no longer to be represented by Global Subordinated Notes and so notifies the Trustee in
writing, or (iii) an Event of Default has occurred and is continuing with respect to the Subordinated Notes and the Depositary or its participant(s) has requested the issuance of Definitive Subordinated Notes. 

Any Global Subordinated Note exchanged in accordance with clause (i) or (ii) above will be so exchanged in whole and not in part, and any
Global Subordinated Note exchanged in accordance with clause (iii) above may be exchanged in whole or from time to time in part as directed by the Depositary. 

Upon the occurrence of any of the preceding events in (i), (ii) or (iii) above, Definitive Subordinated Notes will be issued in fully
registered form, without interest coupons, will have an aggregate principal amount equal to that of the Global Subordinated Note or portion thereof to be so exchanged, will be registered in such names and be in such authorized denominations as the
Depositary will instruct the Trustee in writing and will bear such legends as provided herein. Global Subordinated Notes also may be exchanged or replaced, in whole or in part, as provided in Section 2.09 hereof. Every Subordinated Note
authenticated and delivered in exchange for, or in lieu of, a Global Subordinated Note or any portion thereof, in accordance with this Section 2.07 or Section 2.09 hereof, will be authenticated and delivered in the form of, and will be, a
Global Subordinated Note, except as otherwise provided herein. A Global Subordinated Note may not be exchanged for another Subordinated Note other than as provided in this Section 2.07(3); however, beneficial interests in a Global Subordinated
Note may be transferred and exchanged as provided in Section 2.07(4) hereof. 
 Any Global Subordinated Note to be exchanged in whole
will be surrendered by the Depositary to the Trustee. With regard to any Global Subordinated Note to be exchanged in part, either such Global Subordinated Note will be so surrendered for exchange or, if the Trustee is acting as custodian for the
Depositary or its nominee with respect to such Global Subordinated Note, the principal amount thereof will be reduced, by an amount equal to the portion thereof to be so exchanged, by means of an appropriate adjustment made on the records of the
Trustee. Upon any such surrender or adjustment, the Trustee will authenticate and deliver the Subordinated Note issuable on such exchange to or upon the order of the Depositary or an authorized representative thereof. 

  
 25 












 (4) The transfer and exchange of beneficial interests in the Global Subordinated Notes will
be effected through the Depositary in accordance with the Applicable Procedures and this Section 2.07. 
 (5) A Definitive Subordinated
Note may not be exchanged for a beneficial interest in a Global Subordinated Note unless the Company determines that the Subordinated Notes may be represented by Global Subordinated Notes and so notifies the Trustee. After the Company has determined
that the Subordinated Notes may be represented by Global Subordinated Notes and so notifies the Trustee in writing, then upon receipt by the Trustee of a Definitive Subordinated Note, duly endorsed or accompanied by appropriate instruments of
transfer, in form satisfactory to the Trustee, together with written instructions from such Holder directing the Trustee to make, or to direct the Registrar to make, an adjustment on its books and records with respect to such Global Subordinated
Note to reflect an increase in the aggregate principal amount of the Subordinated Notes represented by the Global Subordinated Note, such instructions to contain information regarding the Depositary account to be credited with such increase, the
Trustee will cancel such Definitive Subordinated Note and cause, or direct the Registrar to cause, in accordance with the standing instructions and procedures existing between the Depositary and the Registrar, the aggregate principal amount of
Subordinated Notes represented by the Global Subordinated Note to be increased by the aggregate principal amount of the Definitive Subordinated Note to be exchanged, and will credit or cause to be credited to the account of the Person specified in
such instructions a beneficial interest in the Global Subordinated Note equal to the principal amount of the Definitive Subordinated Note so cancelled. If no Global Subordinated Notes are then outstanding, the Company will issue and the Trustee will
authenticate, upon Company Order, a new Global Subordinated Note in the appropriate principal amount. 
 (6) At such time as all beneficial
interests in a particular Global Subordinated Note have been exchanged for Definitive Subordinated Notes or a particular Global Subordinated Note has been repurchased or canceled in whole and not in part, each such Global Subordinated Note will be
returned to or retained and canceled by the Trustee in accordance with Section 2.12 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Subordinated Note is exchanged for or transferred to a Person who will
take delivery thereof in the form of a beneficial interest in another Global Subordinated Note or for Definitive Subordinated Notes, the principal amount of Subordinated Notes represented by such Global Subordinated Note will be reduced accordingly
by adjustments made on the records of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global
Subordinated Note, such other Global Subordinated Note will be increased accordingly by adjustments made on the records of the Trustee to reflect such increase. 

  
 26 












 (7) No Restricted Subordinated Note will be transferred or exchanged except in compliance
with the Private Placement Legend or as provided in accordance with Section 2.08. In addition to the provisions for transfer and exchange set forth in this Section 2.07, the Trustee, any Registrar and Paying Agent (if a different Person
than the Trustee) and the Company may, prior to effecting any requested transfer or exchange of any Restricted Subordinated Notes, other than an exchange in accordance with Section 2.08, require that legal counsel to the Holder or owner of
beneficial interests requesting such transfer or exchange deliver to the Trustee, any Registrar and Paying Agent (if a different Person than the Trustee) and the Company, an Opinion of Counsel in compliance with this Indenture and additionally
opining that the transfer or exchange is in compliance with the requirements of the Private Placement Legend and that the Subordinated Note issued to the transferee or in exchange for the Restricted Subordinated Note may be issued free of the
Private Placement Legend. Any untransferred or unexchanged balance of a Restricted Subordinated Note will be reissued to the Holder with the Private Placement Legend, unless the Private Placement Legend may be omitted in accordance with
Section 2.04, as evidenced by the Opinion of Counsel. 
 2.08 Exchange Offer. 

Upon the occurrence of an Exchange Offer in accordance with the Registration Rights Agreement, the Company will issue and, upon receipt of a
Company Order in accordance with Section 2.05 hereof, the Trustee will authenticate (i) Unrestricted Definitive Subordinated Notes in an aggregate principal amount equal to the principal amount of the Restricted Definitive Subordinated
Notes tendered in such Exchange Offer for acceptance by Persons that certify in the applicable Letters of Transmittal that (x) they are not Participating Broker-Dealers, (y) they are not participating in a distribution of the applicable
Exchange Notes and (z) they are not Affiliates of the Company, and accepted for exchange in such Exchange Offer and (ii) one or more Unrestricted Global Subordinated Notes in an aggregate principal amount equal to the aggregate principal
amount of the beneficial interests in the Restricted Global Subordinated Notes tendered in such Exchange Offer for acceptance by Persons that certify in the applicable Letters of Transmittal that (x) they are not Participating Broker-Dealers,
(y) they are not participating in a distribution of the applicable Exchange Notes and (z) they are not Affiliates of the Company, and accepted for exchange in such Exchange Offer. Concurrently with the issuance of such Unrestricted Global
Subordinated Notes upon exchange of Restricted Global Subordinated Notes, the Trustee will cause the aggregate principal amount of the applicable Restricted Global Subordinated Notes to be reduced accordingly, and the Company will execute and the
Trustee will authenticate and deliver to the Persons designated by the Holders of Restricted Definitive Subordinated Notes so accepted Unrestricted Definitive Subordinated Notes in the applicable principal amount. All Subordinated Notes, including
any Initial Notes that remain outstanding after the consummation of such Exchange Offer and Exchange Notes issued in connection with such Exchange Offer, will be treated as a single class of securities under this Indenture. 

2.09 Mutilated, Destroyed, Lost and Stolen Subordinated Notes. 

If any mutilated Subordinated Note is surrendered to the Trustee, subject to the provisions of this Section 2.09, the Company will
execute and the Trustee will authenticate and deliver in exchange therefor a new Subordinated Note containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding. 

  
 27 












 If there be delivered to the Company and to the Trustee (i) evidence to their
satisfaction of the destruction, loss or theft of any Subordinated Note, and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company
or the Trustee that such Subordinated Note has been acquired by a bona fide purchaser, the Company will execute and, upon the Company’s request the Trustee will authenticate and deliver, in exchange for or in lieu of any such destroyed, lost or
stolen Subordinated Note, a new Subordinated Note containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding. 

Notwithstanding the foregoing provisions of this Section 2.09, in case the outstanding principal balance of any mutilated, destroyed,
lost or stolen Subordinated Note has become or is about to become due and payable, or is about to be redeemed by the Company pursuant to Article X hereof, the Company in its discretion may, instead of issuing a new Subordinated Note, pay or redeem
such Subordinated Note, as the case may be, upon surrender of such Subordinated Note or delivery of evidence to the Company’s and Trustee’s satisfaction of the destruction, loss or theft of such Subordinated Note. 

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

Every new Subordinated Note issued in accordance with this Section in lieu of any destroyed, lost or stolen Subordinated Note will constitute
a separate obligation of the Company, whether or not the destroyed, lost or stolen Subordinated Note will be at any time enforceable by anyone, and will be entitled to all the benefits of this Indenture equally and proportionately with any and all
other Subordinated Notes duly issued hereunder. 
 The provisions of this Section, as amended or supplemented in accordance with this
Indenture with respect to particular Subordinated Notes or generally, will (to the extent lawful) be exclusive and will preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Subordinated Notes. 
 2.10 Payment of Interest; Rights to Interest Preserved. 

Any interest on any Subordinated Note that will be payable, and punctually paid or duly provided for, on any Interest Payment Date will be
paid to the Person in whose name such Subordinated Note is registered as of the close of business on the Regular Record Date for such Interest Payment Date. 

Any interest on any Subordinated Note that will be payable, but will not be punctually paid or duly provided for, on any Interest Payment Date
for such Subordinated Note (herein called “Defaulted Interest”) will cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid
by the Company, at its election in each case, as provided in clause (1) or (2) below: 
 (1) The Company may elect to make payment of
any Defaulted Interest to the Person in whose name such Subordinated Note will be registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which will be fixed in the following manner. The Company will
notify the Trustee in writing of the amount of Defaulted 

  
 28 












 
Interest proposed to be paid on such Subordinated Note and the date of the proposed payment, and at the same time the Company will deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or will make arrangements satisfactory to the Trustee for such deposit on or prior to the date of the proposed payment, such money when so deposited to be held in trust for
the benefit of the Person entitled to such Defaulted Interest as in this clause provided. Thereupon, the Company will fix or cause to be fixed a Special Record Date for the payment of such Defaulted Interest, which will be not more than 15 days and
not less than 10 days prior to the date of proposed payment. The Company (or, upon the written request of the Company, the Trustee in the name and at the expense of the Company), will cause notice of the proposed payment of such Defaulted Interest
and the Special Record Date therefor to be delivered to the Holder of such Subordinated Note at the Holder’s address as it appears in the Subordinated Note Register not less than 10 days prior to such Special Record Date. Notice of the proposed
payment of such Defaulted Interest and the Special Record Date therefor having been delivered as aforesaid, such Defaulted Interest will be paid to the Person in whose name such Subordinated Note will be registered at the close of business on such
Special Record Date and will no longer be payable under the following clause (2). 
 (2) The Company may make payment of any Defaulted
Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Subordinated Note may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to
the Trustee of the proposed payment under this Clause, such payment will be deemed practicable by the Trustee. 
 Unless otherwise provided
in or under this Indenture or the Subordinated Notes, at the option of the Company, interest on Subordinated Notes that bear interest may be paid by mailing a check to the address of the Person entitled thereto as such address will appear in the
Subordinated Note Register or by transfer to an account maintained by the payee with a bank located in the United States. 
 Subject to the
foregoing provisions of this Section and Section 2.07, each Subordinated Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Subordinated Note will carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Subordinated Note. 
 2.11 Persons Deemed Owners. 

Prior to due presentment of a Subordinated Note for registration of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name such Subordinated Note is registered in the Subordinated Note Register as the owner of such Subordinated Note for the purpose of receiving payment of principal of, and (subject to Section 2.07 and
Section 2.10) interest on, such Subordinated Note and for all other purposes whatsoever, whether or not any payment with respect to such Subordinated Note will be overdue, and neither the Company, the Trustee or any agent of the Company or the
Trustee will be affected by notice to the contrary. 

  
 29 












 No holder of any beneficial interest in any Global Subordinated Note held on its behalf by a
Depositary will have any rights under this Indenture with respect to such Global Subordinated Note, and such Depositary may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such Global Subordinated
Note for all purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests
of a Global Subordinated Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

Notwithstanding the foregoing, nothing herein will prevent the Company, the Trustee, any Paying Agent or the Registrar from giving effect to
any written certification, proxy or other authorization furnished by the applicable Depositary, as a Holder, with respect to a Global Subordinated Note or impair, as between such Depositary and the owners of beneficial interests in such Global
Subordinated Note, the operation of customary practices governing the exercise of the rights of such Depositary (or its nominee) as the Holder of such Global Subordinated Note. 

2.12 Cancellation. 
 All
Subordinated Notes surrendered for payment, redemption, registration of transfer or exchange will, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Subordinated Note, as well as Subordinated Notes
surrendered directly to the Trustee for any such purpose, will be cancelled promptly by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Subordinated Notes previously authenticated and delivered hereunder which
the Company may have acquired in any manner whatsoever, and all Subordinated Notes so delivered will be cancelled promptly by the Trustee. No Subordinated Notes will be authenticated in lieu of or in exchange for any Subordinated Notes cancelled as
provided in this Section, except as expressly permitted by or under this Indenture. All cancelled Subordinated Notes held by the Trustee will be disposed of in accordance with its procedure for the disposition of cancelled Subordinated Notes and
applicable retention laws, and the Trustee upon the written request of the Company will deliver to the Company a certificate of such disposition, unless by a Company Order the Company shall direct that cancelled Subordinated Notes shall be returned
to the Company. 
 2.13 Computation of Interest. 

(1) The Subordinated Notes will bear interest at a fixed rate of 5.500% per annum from and including March 31, 2022 to, but excluding,
April 1, 2027 or their earlier Redemption Date (the “Fixed Rate Period”). Interest accrued on the Subordinated Notes during the Fixed Rate Period will be payable semi-annually in arrears on April 1 and
October 1 of each year, commencing on October 1, 2022 (each such date, a “Fixed Rate Interest Payment Date”). The last Fixed Rate Interest Payment Date shall be April 1, 2027, unless the Subordinated Notes are
earlier redeemed. The interest payable during the Fixed Rate Period will be paid to each Holder in whose name a Subordinated Note is registered at the close of business on the fifteenth day (whether or not a Business Day) immediately preceding the
applicable Fixed Rate Interest Payment Date (each such date, a “Fixed Rate Regular Record Date”). 

  
 30 












 (2) The Subordinated Notes will bear a floating interest rate from, and including
April 1, 2027, to, but excluding, the Maturity Date or their earlier Redemption Date (the “Floating Rate Period”). The floating interest rate will be reset quarterly, and the interest rate for any Floating Rate Period
shall be equal to the then-current Three-Month Term SOFR (or other applicable Benchmark) plus 315 basis points for each quarterly Interest Period during the Floating Rate Period. During the Floating Rate Period, interest on the Subordinated Notes
will be payable quarterly in arrears on January 1, April 1, July 1 and October 1, of each year commencing, on July 1, 2027 (each such date, a “Floating Rate Interest Payment Date” and, together with a
Fixed Rate Interest Payment Date, an “Interest Payment Date”). The interest payable during the Floating Rate Period will be paid to each Holder in whose name a Subordinated Note is registered at the close of business on the
fifteenth day (whether or not a Business Day) immediately preceding the applicable Floating Rate Interest Payment Date (each such date, a “Floating Rate Regular Record Date”). Notwithstanding the foregoing, if Three-Month
Term SOFR (or other applicable Benchmark) is less than zero, then Three-Month Term SOFR (or other such Benchmark) shall be deemed to be zero. The Calculation Agent will provide the Company and the Trustee with the interest rate in effect on the
Subordinated Notes promptly after the Reference Time (or such other date of determination for the applicable Benchmark). 
 (3) The amount
of interest payable on any Fixed Rate Interest Payment Date during the Fixed Rate Period will be computed on the basis of a 360-day year consisting of twelve 30-day
months to, but excluding, April 1, 2027, and, the amount of interest payable on any Floating Rate Interest Payment Date during the Floating Rate Period will be computed on the basis of a 360-day year on
the basis of the actual number of days elapsed. 
 (4) The Company or the Calculation Agent, as applicable, shall calculate the amount of
interest payable on any Interest Payment Date and the Trustee shall have no duty to confirm or verify any such calculation. In the event that any scheduled Interest Payment Date or the Maturity Date for the Subordinated Notes falls on a day that is
not a Business Day, then payment of interest payable on such Interest Payment Date or of principal and interest payable on the Maturity Date will be paid on the next succeeding day which is a Business Day (any payment made on such date will be
treated as being made on the date that the payment was first due and no interest on such payment will accrue for the period from and after such scheduled Interest Payment Date); provided, that in the event that any scheduled Floating Rate Interest
Payment Date falls on a day that is not a Business Day and the next succeeding Business Day falls in the next succeeding calendar month, such Floating Rate Interest Payment Date will be accelerated to the immediately preceding Business Day, and, in
each such case, the amounts payable on such Business Day will include interest accrued to, but excluding, such Business Day. U.S. Dollar amounts resulting from interest calculations will be rounded to the nearest cent, with one-half cent being rounded upward. 
 (5) The Company shall take such actions as are necessary to ensure
that from the commencement of the Floating Rate Period for so long as any of the Subordinated Notes remain outstanding there will at all times be a Calculation Agent appointed to calculate Three-Month Term SOFR in respect of each Floating Rate
Period. The calculation of Three-Month Term SOFR for each applicable Floating Rate Period by the Calculation Agent will (in the absence of manifest error) be final and binding. The Calculation Agent’s determination of any interest rate and its
calculation of interest payments for any period will be maintained on file at the Calculation Agent’s principal offices, will be made available to any Holder of the Subordinated Notes upon request and will be provided to the Trustee. The
Calculation Agent shall have all the rights, protections and indemnities afforded to the Trustee hereunder. The Calculation Agent may be removed by the Company at any time. If the Calculation Agent is unable or unwilling to act as Calculation Agent


  
 31 












 
or is removed by the Company, the Company will promptly appoint a replacement Calculation Agent. The Calculation Agent may not resign its duties without a successor having been duly appointed;
provided, that if a successor Calculation Agent has not been appointed by the Company and such successor accepted such position within 30 days after the giving of notice of resignation by the Calculation Agent, then the resigning Calculation Agent
may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Calculation Agent with respect to such series. The Trustee shall not be under any duty to succeed to, assume or otherwise perform,
any duties of the Calculation Agent, or to appoint a successor or replacement in the event of the Calculation Agent’s resignation or removal or to replace the Calculation Agent in the event of a default, breach or failure of performance on the
part of the Calculation Agent with respect to the Calculation Agent’s duties and obligations hereunder. For the avoidance of doubt, if at any time there is no Calculation Agent appointed by the Company, then the Company shall be the Calculation
Agent. The Company may appoint itself or any of its Affiliates to be the Calculation Agent. 
 (6) Effect of Benchmark Transition Event.

 (a) If the Calculation Agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred on or
prior to the Reference Time in respect of any determination of the Benchmark on any date, then the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Subordinated Notes during the Floating Rate Period in
respect of such determination on such date and all determinations on all subsequent dates. In connection with the implementation of a Benchmark Replacement, the Calculation Agent will have the right to make Benchmark Replacement Conforming Changes
from time to time. 
 (b) Notwithstanding anything set forth in clause (2) of Section 2.13 above, if the Calculation Agent
determines on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR (or other applicable Benchmark), then the provisions set forth in
clause (6) of this Section 2.13 will thereafter apply to all determinations of the interest rate on the Subordinated Notes during the Floating Rate Period. After a Benchmark Transition Event and its related Benchmark Replacement Date have
occurred, the interest rate on the Subordinated Notes for each Interest Period during the Floating Rate Period will be an annual rate equal to the Benchmark Replacement plus 315 basis points. 

(c) The Calculation Agent is expressly authorized to make certain determinations, decisions and elections under the terms of the Subordinated
Notes, including with respect to the use of Three-Month Term SOFR as the Benchmark and under clause (6) of this Section 2.13. Any determination, decision or election that may be made by the Calculation Agent under the terms of the
Subordinated Notes, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from
taking any action or selection (A) will be conclusive and binding on the Holders of the Subordinated Notes and the Trustee absent manifest error, (B) if made by the Company as Calculation Agent, will be made in the Company’s sole
discretion, (C) if made by a Calculation Agent other than the Company, will be made after consultation with the Company, and the Calculation Agent will not make any such determination, decision or election


  
 32 












 
to which the Company reasonably objects and (D) notwithstanding anything to the contrary herein, shall become effective without consent from the Holders of the Subordinated Notes, the
Trustee or any other party. If the Calculation Agent fails to make any determination, decision or election that it is required to make under the terms of the Subordinated Notes, then the Company will make such determination, decision or election on
the same basis as described above. 
 (d) The Company (or its Calculation Agent) shall notify the Trustee in writing (i) upon the
occurrence of the Benchmark Transition Event or the Benchmark Replacement Date, and (ii) of any Benchmark Replacements, Benchmark Replacement Conforming Changes and other items affecting the interest rate on the Subordinated Notes after a
Benchmark Transition Event. 
 (e) The Trustee (including in its capacity as Paying Agent) shall have no (i) responsibility or
liability for the (A) Three-Month Term SOFR Conventions, (B) selection of an alternative reference rate to Three-Month Term SOFR (including, without limitation, whether the conditions for the designation of such rate have been satisfied or
whether such rate is a Benchmark Replacement or an Unadjusted Benchmark Replacement), (C) determination or calculation of a Benchmark Replacement, or (D) determination of whether a Benchmark Transition Event or Benchmark Replacement Date has
occurred, and in each such case under clauses (A) through (D) above shall be entitled to conclusively rely upon the selection, determination, and/or calculation thereof as provided by the Company or its Calculation Agent, as applicable, and
(ii) liability for any failure or delay in performing its duties hereunder as a result of the unavailability of a Benchmark rate as described in the definition thereof, including, without limitation, as a result of the Company’s or
Calculation Agent’s failure to select a Benchmark Replacement or the Calculation Agent’s failure to calculate a Benchmark. The Trustee shall be entitled to rely conclusively on all notices from the Company or its Calculation Agent
regarding any Benchmark or Benchmark Replacement, including, without limitation, with regard to Three-Month Term SOFR Conventions, a Benchmark Transition Event, Benchmark Replacement Date, and Benchmark Replacement Conforming Changes. The Trustee
shall not be responsible or liable for the actions or omissions of the Calculation Agent, or any failure or delay in the performance of the Calculation Agent’s duties or obligations, nor shall it be under any obligation to monitor or oversee
the performance of the Calculation Agent. The Trustee shall be entitled to conclusively rely on any determination made, and any instruction, notice, Officers’ Certificate or other instruction or information provided by the Calculation Agent
without independent verification, investigation or inquiry of any kind. The Trustee shall not be obligated to enter into any amendment or supplement hereto that adversely impacts its rights, duties, obligations, immunities or liabilities (including,
without limitation, in connection with the adoption of any Benchmark Replacement Conforming Changes). 
 (f) If the then-current Benchmark
is Three-Month Term SOFR, the Calculation Agent will have the right to establish the Three-Month Term SOFR Conventions, and if any of the foregoing provisions concerning the calculation of the interest rate and the payment of interest during the
Floating Rate Period are inconsistent with any of the Three-Month Term SOFR Conventions determined by the Calculation Agent, then the relevant Three-Month Term SOFR Conventions will apply. 

  
 33 












 2.14 CUSIP Numbers. 

The Company may issue the Subordinated Notes with one or more “CUSIP” numbers (if then generally in use). The Company will promptly
notify the Trustee in writing of any change in the CUSIP numbers. The Trustee may use “CUSIP” numbers in notices (including but not limited to notices of redemption or exchange) as a convenience to Holders; provided that any such notice
may state that no representation is made as to the correctness of such numbers either as printed on the Subordinated Notes or as contained in any notice (including any notice of redemption or exchange) and that reliance may be placed only on the
other identification numbers printed on the Subordinated Notes, and any such notice will not be affected by any defect in or omission of such numbers. 

ARTICLE III 

SATISFACTION AND DISCHARGE OF INDENTURE 

3.01 Satisfaction and Discharge. 

This Indenture will cease to be of further effect, and the Trustee, on receipt of a Company Order, at the expense of the Company, will execute
proper instruments acknowledging satisfaction and discharge of this Indenture, when 
 (1) either 

(a) all Subordinated Notes theretofore authenticated and delivered (other than (i) Subordinated Notes that have been destroyed, lost or
stolen and which have been replaced or paid as provided in Section 2.09 and (ii) Subordinated Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the
Company or discharged from such trust, as provided in Section 9.03) have been delivered to the Trustee for cancellation; or 
 (b) all
Subordinated Notes that have not been delivered to the Trustee for cancellation (i) have become due and payable, or (ii) will become due and payable at their Stated Maturity within one year, or (iii) if redeemable at the option of the
Company, are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, and the Company, in the case of (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 sufficient to pay and discharge the entire indebtedness on such Subordinated Notes not theretofore delivered to the
Trustee for cancellation, including the principal of, and interest on, such Subordinated Notes, to the date of such deposit (in the case of Subordinated Notes which have become due and payable) or to the Stated Maturity thereof, as the case may be;

 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the Outstanding
Subordinated Notes; and 
 (3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each
stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture have been satisfied. 

  
 34 












 Notwithstanding the satisfaction and discharge of this Indenture with respect to the
Subordinated Notes, the obligations of the Company to the Trustee under Section 5.07 and, if money will have been deposited with the Trustee in accordance with Section 3.01(1)(b), the obligations of the Company and the Trustee with respect
to the Subordinated Notes under Section 3.03 and Section 9.03 will survive. 
 3.02 Defeasance and Covenant Defeasance.

 (1) The Company may, at its option and at any time, elect to have Section 3.02(2) or Section 3.02(3) be applied to such
Outstanding Subordinated Notes upon compliance with the conditions set forth below in this Section 3.02. Legal Defeasance and Covenant Defeasance may be effected only with respect to all, and not less than all, of the Outstanding Subordinated
Notes. 
 (2) Upon the Company’s exercise of the above option applicable to this Section 3.02(2), the Company will be deemed to
have been discharged from its obligations with respect to such Outstanding Subordinated Notes on the date the conditions set forth in clause (4) of this Section 3.02 are satisfied (“Legal Defeasance”). For this
purpose, “Legal Defeasance” means that the Company will be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Subordinated Notes, which will thereafter be deemed to be “Outstanding” only
for the purposes of Section 3.02(5) and the other Sections of this Indenture referred to in clauses (i) through (iv) of this paragraph, and to have satisfied all of its other obligations under such Subordinated Notes and this Indenture
insofar as such Subordinated Notes are concerned (and the Trustee, at the expense of the Company, will execute proper instruments acknowledging the same), except for the following which will survive until otherwise terminated or discharged
hereunder: (i) the rights of Holders of such Outstanding Subordinated Notes to receive, solely from the trust fund described in Section 3.02(4)(a) and as more fully set forth in this Section 3.02 and Section 3.03, payments in
respect of the principal of and interest, if any, on, such Subordinated Notes when such payments are due, (ii) the obligations of the Company and the Trustee with respect to such Subordinated Notes under Section 2.07, Section 2.09,
Section 9.02 and Section 9.03, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 3.02 and Section 3.03. The Company may exercise its option under this
Section 3.02(2) notwithstanding the prior exercise of its option under Section 3.02(3) with respect to such Subordinated Notes. 

(3) Upon the Company’s exercise of the above option applicable to this Section 3.02(3), the Company will be released from its
obligations under clauses (ii) and (iii) of Section 9.04 and under Section 9.05, Section 9.06 and Section 9.07 on and after the date the conditions set forth in Section 3.02(4) are satisfied (“Covenant
Defeasance”), and such Subordinated Notes will thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in
connection with any such covenant, but will continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such Covenant Defeasance means that with respect to such Outstanding Subordinated Notes, the Company may
omit to comply with, and will have no liability in respect of, any term, condition or limitation set forth in any such Section or any such other covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such
Section or such other covenant or by reason of reference in any such Section or such other covenant to any other provision herein or in any other document and such omission to comply will not constitute a default, but, except as specified above, the
remainder of this Indenture and such Subordinated Notes will be unaffected thereby. 

  
 35 












 (4) The following will be the conditions to application of Section 3.02(2) or
Section 3.02(3) to any Outstanding Subordinated Notes: 
 (a) The Company will irrevocably have deposited or caused to be deposited
with the Trustee (or another trustee satisfying the requirements of Section 5.08 who will agree to comply with the provisions of this Section 3.02 applicable to it) as trust funds in trust for the purpose of making the following payments,
specifically pledged as security for, and dedicated solely to, the benefit of the Holders, (i) an amount in Dollars, (ii) Government Obligations that through the scheduled payment of principal and interest in respect thereof in accordance
with their terms will provide, not later than one day before the due date of any payment of principal of and interest, if any, on such Subordinated Notes, money or (iii) a combination thereof, in any case, in an amount, sufficient, without
consideration of any reinvestment of such principal and interest, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which
will be applied by the Trustee (or other qualifying trustee) to pay and discharge, the principal of and interest, if any, on, such Outstanding Subordinated Notes on the Stated Maturity of such principal or installment of principal or interest or the
applicable Redemption Date, as the case may be. 
 (b) Such Legal Defeasance or Covenant Defeasance will not result in a breach or
violation of, or constitute a default under, this Indenture or any other material agreement or instrument to which the Company or any Subsidiary is a party or by which it is bound. 

(c) No Event of Default or event which with notice or lapse of time or both would become an Event of Default with respect to such
Subordinated Notes will have occurred and be continuing on the date of such deposit, and, solely in the case of Legal Defeasance under Section 3.02(2), no Event of Default, or event which with notice or lapse of time or both would become an
Event of Default, under Section 4.01 will have occurred and be continuing at any time during the period ending on and including the 91st day after the date of such deposit (it being
understood that this condition to Legal Defeasance under Section 3.02(2) will not be deemed satisfied until the expiration of such period). 

(d) In the case of Legal Defeasance, the Company will have delivered to the Trustee an Opinion of Counsel in form reasonably acceptable to
the Trustee stating that (i) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (ii) since the date of this Indenture there has been a change in applicable federal income tax law, in
either case to the effect that, and based thereon such opinion of independent counsel will confirm that, the Holders of such Outstanding Subordinated Notes will not recognize income, gain or loss for federal income tax purposes as a result of such
Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred. 

(e) In the case of Covenant Defeasance, the Company will have delivered to the Trustee an Opinion of Counsel in form reasonably acceptable to
the Trustee to the effect that the Holders of such Outstanding Subordinated Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same
amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred. 

  
 36 












 (f) The Company will have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent to the Legal Defeasance or Covenant Defeasance, as the case may be, under this Indenture have been satisfied. 

(g) If the moneys or Government Obligations or combination thereof, as the case may be, deposited under Section 3.02(4)(a) above are
sufficient to pay the principal of, and interest, if any, on, such Subordinated Notes provided such Subordinated Notes are redeemed on a particular Redemption Date, the Company will have given the Trustee irrevocable instructions to redeem such
Subordinated Notes on such date and to provide notice of such redemption to Holders as provided in or under this Indenture. 
 (h) The
Trustee will have received such other documents, assurances and Opinions of Counsel as the Trustee will have reasonably required. 
 (5)
Subject to the provisions of the last paragraph of Section 9.03, all money and Government Obligations deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 3.02(5), the
“Trustee”) in accordance with Section 3.02(4)(a) in respect of any Outstanding Subordinated Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Subordinated Notes and this
Indenture, to the payment, either directly or through any Paying Agent (other than the Company or any Subsidiary or Affiliate of the Company acting as Paying Agent) as the Trustee may determine, to the Holders of all sums due and to become due
thereon in respect of principal and interest but such money and Government Obligations need not be segregated from other funds, except to the extent required by law. 

The Company will pay and indemnify the Trustee against any tax, fee or other charge, imposed on or assessed against the Government Obligations
deposited in accordance with this Section 3.02 or the principal or interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Subordinated Notes. 

3.03 Application of Trust Money. 

Subject to the provisions of the last paragraph of Section 9.03, all money and Government Obligations deposited with the Trustee in
accordance with Section 3.01 or Section 3.02 will be held in trust and applied by the Trustee, in accordance with the provisions of such Subordinated Notes subject to discharge under Section 3.01 or Legal Defeasance or Covenant
Defeasance under Section 3.02, and this Indenture, to the payment, either directly or through any Paying Agent (including the Company, acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the
principal and interest for whose payment such money has or Government Obligations have been deposited with or received by the Trustee; but such money and Government Obligations need not be segregated from other funds, except to the extent required
by law. 

  
 37 












 3.04 Reinstatement. 

If the Trustee (or other qualifying trustee appointed in accordance with Section 3.02(4)(a)) or any Paying Agent is unable to apply any
moneys or Government Obligations deposited in accordance with Section 3.01(1) or Section 3.02(4)(a) to pay any principal of, or interest, if any, on, the Subordinated Notes by reason of any legal proceeding or any order or judgment of any
court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s obligations under this Indenture and the Subordinated Notes will be revived and reinstated as though no such deposit had
occurred, until such time as the Trustee (or other qualifying trustee) or Paying Agent is permitted to apply all such moneys and Government Obligations to pay the principal of, and interest, if any, on the Subordinated Notes as contemplated by
Section 3.01 or Section 3.02 as the case may be; provided, however, that if the Company makes any payment of the principal of, or interest if any on, the Subordinated Notes following the reinstatement of its obligations as aforesaid, the
Company will be subrogated to the rights of the Holders of such Subordinated Notes to receive such payment from the funds held by the Trustee (or other qualifying trustee) or Paying Agent. 

3.05 Effect on Subordination Provisions. 

The provisions of Article XI are expressly made subject to the provisions for, and to the right of the Company to effect, the satisfaction and
discharge of all of the Subordinated Notes as set forth in and in accordance with Section 3.01 and the provisions for, and to the right of the Company to effect, Legal Defeasance and Covenant Defeasance of all of the Subordinated Notes as set
forth in and in accordance with Section 3.02. As a result, and anything herein to the contrary notwithstanding, if the Company complies with the provisions of Section 3.01 to effect the satisfaction and discharge of the Subordinated Notes
or complies with the provisions of Section 3.02 to effect the Legal Defeasance or Covenant Defeasance, upon the effectiveness of such satisfaction and discharge in accordance with Section 3.01 or of Legal Defeasance or Covenant Defeasance
in accordance with Section 3.02, in the case of satisfaction and discharge in accordance with Section 3.01, or, in the case of Legal Defeasance or Covenant Defeasance in accordance with Section 3.02, the Subordinated Notes as to which
Legal Defeasance or Covenant Defeasance, as the case may be, will have become effective will thereupon cease to be so subordinated in right of payment to the Senior Indebtedness and will no longer be subject to the provisions of Article XI and,
without limitation to the foregoing, all moneys and Government Obligations deposited with the Trustee (or other qualifying trustee) in trust in connection with such satisfaction and discharge. Legal Defeasance or Covenant Defeasance, as the case may
be, and all proceeds therefrom may be applied to pay the principal of, and interest, if any, on, such Subordinated Notes as and when the same will become due and payable notwithstanding the provisions of Article XI without regard to whether any or
all of the Senior Indebtedness then outstanding will have been paid or otherwise provided for. 

  
 38 












 ARTICLE IV 

REMEDIES 
 4.01 Events
of Default; Acceleration. 
 An “Event of Default” means any one of the following events (whatever the reason for such Event
of Default and whether it will be voluntary or involuntary or be effected by operation of law or in accordance with any judgment, decree, or order of any court or any order, rule, or regulation of any administrative or governmental body): 

(1) the entry of a decree or order for relief in respect of the Company by a court having jurisdiction in the premises in an involuntary case
or proceeding under any applicable bankruptcy, insolvency, or reorganization law, now or hereafter in effect of the United States or any political subdivision thereof, and such decree or order will have continued unstayed and in effect for a period
of 60 consecutive days; 
 (2) the commencement by the Company of a voluntary case under any applicable bankruptcy, insolvency or
reorganization law, now or hereafter in effect of the United States or any political subdivision thereof, or the consent by the Company to the entry of a decree or order for relief in an involuntary case or proceeding under any such law; 

(3) the failure of the Company to pay any installment of interest on any of the Subordinated Notes as and when the same will become due and
payable, and the continuation of such failure for a period of 30 days; 
 (4) the failure of the Company to pay all or any part of the
principal of any of the Subordinated Notes as and when the same will become due and payable under this Indenture; 
 (5) the failure of the
Company to perform any other covenant or agreement on the part of the Company contained in the Subordinated Notes or in this Indenture, and the continuation of such failure for a period of 60 days after the date on which notice specifying such
failure, stating that such notice is a “Notice of Default” hereunder and demanding that the Company remedy the same, will have been given, in the manner set forth in Section 1.05, to the Company by the Trustee, or to the Company and
the Trustee by the Holders of at least 25% in aggregate principal amount of the Subordinated Notes at the time Outstanding; or 
 (6) the
default by the Company under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company having an aggregate principal amount outstanding of at least $30,000,000, whether such indebtedness now exists or is created
or incurred in the future, which default (i) constitutes a failure to pay any portion of the principal of such indebtedness when due and payable after the expiration of any applicable grace period or (ii) results in such indebtedness
becoming due or being declared due and payable prior to the date on which it otherwise would have become due and payable without, in the case of clause (i), such indebtedness having been discharged or, in the case of clause (ii), without such
indebtedness having been discharged or such acceleration having been rescinded or annulled. 
 Upon becoming aware of any Event of Default,
the Company will promptly deliver to the Trustee a written statement specifying the Event of Default. 

  
 39 












 If an Event of Default described in Section 4.01(1) or 4.01(2) occurs, then the
principal amount of all of the Outstanding Subordinated Notes, and accrued and unpaid interest, if any, on all Outstanding Subordinated Notes will become and be immediately due and payable without any declaration or other act on the part of the
Trustee or any Holder, and the Company waives demand, presentment for payment, notice of nonpayment, notice of protest, and all other notices. Notwithstanding the foregoing, upon the occurrence of an Event of Default other than an Event of Default
described in Section 4.01(1) or 4.01(2), neither the Trustee nor any Holder may accelerate the Stated Maturity of the Subordinated Notes and make the principal of, and any accrued and unpaid interest on, the Subordinated Notes, immediately due
and payable. 
 If any Event of Default occurs and is continuing, the Trustee may also pursue any other available remedy, at law or in
equity, to collect the payment of principal of, and interest on, the Subordinated Notes or to enforce the performance of any provision of the Subordinated Notes or this Indenture. 

4.02 Failure to Make Payments. 

If an Event of Default described in Section 4.01(3) or Section 4.01(4) occurs, the Company will, upon demand of the Trustee, pay to
the Trustee, for the benefit of the Holders of such Subordinated Notes, the whole amount then due and payable with respect to such Subordinated Notes, with interest upon the overdue principal, and, to the extent permitted by applicable law, upon any
overdue installments of interest at the rate or respective rates, as the case may be, provided for or with respect to such Subordinated Notes or, if no such rate or rates are so provided, at the rate or respective rates, as the case may be, of
interest borne by such Subordinated Notes, and, in addition thereto, such further amount of money as will be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel and all other amounts due to the Trustee under Section 5.07. 
 If the Company fails to pay the money
it is required to pay the Trustee, 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, may prosecute such proceeding to judgment or final decree, and
may enforce the same against the Company or any other obligor upon such Subordinated Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company, wherever situated. 

The Trustee may proceed to protect and enforce its rights and the rights of the Holders of Subordinated Notes by such appropriate judicial
proceedings as the Trustee will deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted in this Indenture, or to
enforce any other proper remedy. 
 Upon an Event of Default, the Company may not declare or pay any dividends or distributions on, or
redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Company’s capital stock, make any payment of principal or interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Company
that rank equal with or junior to the Subordinated Notes, or make any payments under any guarantee that ranks equal with or junior to the Subordinated Notes, other than: (i) any dividends or distributions in shares of, or options, warrants or
rights to subscribe for or purchase shares of, any class of Company’s common 

  
 40 












 
stock; (ii) any declaration of a dividend in connection with the implementation of a shareholders’ rights plan, or the issuance of stock under any such plan in the future, or the
redemption or repurchase of any such rights pursuant thereto; (iii) as a result of a reclassification of Company’s capital stock or the exchange or conversion of one class or series of Company’s capital stock for another class or
series of Company’s capital stock; (iv) the purchase of fractional interests in shares of Company’s capital stock in accordance with the conversion or exchange provisions of such capital stock or the security being converted or
exchanged; or (v) purchases of any class of Company’s common stock related to the issuance of common stock or rights under any benefit plans for Company’s directors, officers or employees or any of Company’s dividend reinvestment
plans. 
 4.03 Trustee May File Proofs of Claim. 

In case of any judicial proceeding relative to the Company (or any other obligor upon the Subordinated Notes), its property or its creditors,
the Trustee will be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding.
In particular, the Trustee will be authorized to 
 (1) file and prove a claim for the whole amount, or such lesser amount as may be
provided for in the Subordinated Notes, of the principal and interest owing and unpaid in respect of such Subordinated Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee
(including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents or counsel) and of the Holders of such Subordinated Notes allowed in such judicial proceeding, and 

(2) collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; 

and any custodian, receiver, assignee, trustee, liquidator, sequestrator, or other similar official in any such judicial proceeding is authorized by each
Holder to make such payments to the Trustee and, in the event that the Trustee will consent to the making of such payments directly to the Holders and to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements,
and advances of the Trustee, its agents and counsel, and any other amounts due hereunder. 
 No provision of this Indenture will 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 Subordinated Notes or the rights of any Holder or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding; provided, however, the Trustee may vote on behalf of the Holders for the election of a trustee in bankruptcy or similar official and may be a member of a creditors, or
other similar committee.

 4.04 Trustee May Enforce Claims Without Possession of Subordinated Notes. 

All rights of action and claims under this Indenture or the Subordinated Notes may be prosecuted and enforced by the Trustee without the
possession of any of the Subordinated Notes or the production of such Subordinated Notes in any related proceeding, and any such proceeding instituted by the Trustee will be brought in its own name as trustee of an express trust, and any recovery of
judgment will, after provision for the payment of the reasonable compensation, expenses, disbursements, and advances of the Trustee, its agents, and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been
recovered. 
 4.05 Application of Money Collected. 

Any money collected by the Trustee in accordance with this Article IV or, after an Event of Default, any money or other property distributable
in respect of the Company’s obligations under this Indenture will be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal or any interest, upon
presentation of the Subordinated Notes and the notation on such Subordinated Notes of the payment if only partially paid and upon surrender of such Subordinated Notes if fully paid:

Notes for principal and interest, respectively; and 
 FOURTH: The balance, if any, to the Person or Persons entitled thereto. 

4.06 Limitation on Suits. 

No Holder of any Subordinated Note will have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture or
any Subordinated Notes, or for the appointment of a receiver or trustee, or for any other remedy under this Indenture, unless: 
 (1) such
Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Subordinated Notes; 
 (2)
the Holders of not less than 25% in aggregate principal amount of the Outstanding Subordinated Notes will have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under the
Indenture; 
 (3) such Holder or Holders have offered to the Trustee security and indemnity reasonably satisfactory to the Trustee against
the costs, expenses, and liabilities to be incurred in compliance with such request; 

  
 42 












 (4) the Trustee for 60 days after its receipt of such notice, request, and offer of
indemnity has failed to institute any such proceeding; 
 (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 Subordinated Notes; and 

(6) such notification, request, and offer of indemnity are hereby declared in every case at the option of the Trustee to be conditions
precedent to the execution of the powers and trusts of this Indenture, and to any action or cause of action for the enforcement of this Indenture, or for the appointment of a receiver or for any other remedy hereunder; 

it being understood and intended that no one or more of such Holders will have any right in any manner whatever by virtue of, or by availing of, any provision
of this Indenture to affect, disturb, or prejudice the rights of any other of such Holders, 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
provided in this Indenture and for the equal and ratable benefit of all of such Holders. 
 4.07 Unconditional Right of Holders to
Payments. 
 Notwithstanding any other provision in this Indenture, the Holder of any Subordinated Note will have the right, which is
absolute and unconditional, to receive payment of the principal of and (subject to Section 2.07 and Section 2.10) any interest on such Subordinated Note on the respective Stated Maturity or Maturities expressed in such Subordinated Note
(or, in the case of redemption, on the Redemption Date), and to institute suit for the enforcement of any such payment and such rights will not be impaired without the consent of such Holder. 

4.08 Restoration of Rights and Remedies. 

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Company, the Trustee and the Holders will be restored
severally and respectively to their former positions under this Indenture, and thereafter all rights and remedies of the Trustee and the Holders will continue as though no such proceeding had been instituted. 

4.09 Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost, or stolen Subordinated Notes in the
last paragraph of Section 2.09, no right or remedy conferred in this Indenture upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy will, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given under this Indenture or now or in the future existing at law or in equity or otherwise. The assertion or employment of any right or remedy under this Indenture, or
otherwise, will not prevent the concurrent assertion or employment of any other appropriate right or remedy. 

  
 43 












 4.10 Delay or Omission Not Waiver. 

No delay or omission of the Trustee or of any Holder of any Subordinated Notes to exercise any right or remedy accruing upon any Event of
Default will impair any such right or remedy or constitute a waiver of or acquiescence in any such Event of Default. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 4.11 Control by Holders. 

The Holders of a majority in aggregate principal amount of the Outstanding Subordinated Notes will 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 Subordinated Notes, provided that 

(1) such direction will not violate any rule of law or this Indenture or the Subordinated Notes. 

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and 

(3) the Trustee will have the right to decline to follow any such direction if the Trustee in good faith will determine that the proceeding so
directed would involve the Trustee in personal liability. 
 4.12 Waiver of Past Defaults. 

The Holders of not less than a majority in aggregate principal amount of the Outstanding Subordinated Notes may on behalf of the Holders of
all the Subordinated Notes waive any past default under this Indenture and its consequences, except a default in the payment of the principal of, or interest on, any Subordinated Note, or in respect of a covenant or provision of this Indenture which
under Article VIII cannot be modified or amended without the consent of the Holder of each Outstanding Subordinated Note. 
 Upon any such
waiver, such default will cease to exist, and any Event of Default arising from such default will be deemed to have been cured, for every purpose of this Indenture; but no such waiver will extend to any subsequent or other default or impair any
consequent right. 
 4.13 Undertaking for Costs. 

All parties to this Indenture agree, and each Holder of any Subordinated Notes by his acceptance of such Subordinated Notes will 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, suffered, 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 attorney’s fees and expenses, 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 4.13 will not apply to 

  
 44 












 
any suit instituted by the Company, 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 principal amount of
the Outstanding Subordinated Notes, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or interest, if any, on any Subordinated Notes on or after the Stated Maturity or Maturities expressed in such
Subordinated Notes (or, in the case of redemption, on or after the Redemption Date).

 5.01

with the same rights that it would have if it were not Trustee, Authenticating Agent, Paying Agent, Registrar or such other Person. 

  
 48 












 The Trustee is subject to Section 311(a) of the Trust Indenture Act, excluding any
creditor relationship listed in Section 311(b) of the Trust Indenture Act. A Trustee who has resigned or been removed shall be subject to Section 311(a) of Trust Indenture Act to the extent indicated. 

5.06 Money Held in Trust. 

Except as provided in Section 3.02(5), Section 3.03 and Section 9.03, money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law. All moneys held by the Trustee hereunder will be held uninvested. The Trustee will be under no liability for interest on any money received by it hereunder except as otherwise agreed
in writing with the Company. 
 5.07 Compensation and Reimbursement. 

The Company agrees: 
 (1) to pay
to the Trustee from time to time compensation for all ordinary services rendered by the Trustee acting in any capacity hereunder (which compensation will not be limited by any provision of law in regard to the compensation of a trustee of an express
trust); 
 (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents, accountants, consultants, counsel and other
experts employed by it in the exercise and performance of its powers and duties as Trustee), except any such expense, disbursement or advance attributable to the Trustee’s gross negligence or willful misconduct; 

(3) additionally, if it should become necessary that the Trustee perform extraordinary services, it shall be entitled to reasonable extra
compensation and to reimbursement for reasonable extraordinary expenses in connection therewith; provided that if such extraordinary services or expense are occasioned by the gross negligence, bad faith, or willful misconduct of the Trustee, it
shall not be entitled to such compensation or reimbursement; and 
 (4) to indemnify, defend protect and hold each of the Trustee acting in
any capacity or any predecessor Trustee and their agents, accountants, consultants, counsel and other experts employed by it in the exercise and performance of its powers and duties as Trustee harmless from and against any and all losses,
liabilities, damages, costs or expenses suffered or incurred by it arising out of or in connection with the acceptance or administration of its duties under this Indenture, including the costs and expenses of enforcing this Indenture against the
Company and defending itself against any claim (whether asserted by the Company, any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such
loss, liability or expense may be attributable to its gross negligence or willful misconduct, as determined by a final, non-appealable judgment of 

  
 49 












 
a court of competent jurisdiction, and the fees and disbursements of the Trustee’s agents, legal counsel, accountants and experts) and including taxes (other than taxes based upon, measured
by or determined by the income of the Trustee). The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Company will not relieve the Company of its obligations hereunder. The
Company will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the reasonable fees and expenses of such counsel. 

The obligations of the Company under this Section 5.07 will survive the satisfaction and discharge of this Indenture. 

As security for the performance of the obligations of the Company under this Section, the Trustee will have a lien prior to the Subordinated
Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of, or interest on, Subordinated Notes. Such lien will survive the satisfaction and discharge hereof and the
resignation or removal of the Trustee. 
 Any compensation or expense incurred by the Trustee after a default specified by Section 4.01
is intended to constitute an expense of administration under any then applicable bankruptcy or insolvency law. “Trustee” for purposes of this Section 5.07 will include any predecessor Trustee, but the negligence or bad faith of any
Trustee will not affect the rights of any other Trustee under this Section 5.07. The provisions of this Section 5.07 will, to the extent permitted by law, survive any termination of this Indenture (including, without limitation,
termination in accordance with any Bankruptcy Laws) and the resignation or removal of the Trustee.

 (1) There will at all times be a Trustee hereunder that is a corporation, organized and doing business under the laws of
the United States, any state thereof or the District of Columbia, eligible under Section 310(a)(1) of the Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act and that has a combined capital and
surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000 and is subject to supervision or examination by federal or state authority. The Trustee will also satisfy the requirements of
Section 310(a)(5) of the Trust Indenture Act. If at any time the Trustee will cease to be eligible in accordance with the provisions of this Section, it will resign immediately in the manner and with the effect hereinafter specified in this
Article. 
 (2) The Trustee will comply with Section 310(b) of the Trust Indenture Act; provided, however, that there will be excluded
from the operation of Section 310(b)(1) of the Trust Indenture Act this Indenture or any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Company are outstanding if the
requirements for such exclusion set forth in Section 310(b)(1) of the Trust Indenture Act are met. 
 5.09 Resignation and Removal;
Appointment of Successor. 
 (1) No resignation or removal of the Trustee and no appointment of a successor Trustee in accordance with
this Article V will become effective until the acceptance of appointment by the successor Trustee in accordance with Section 5.10. 

  
 50 












 (2) The Trustee may resign at any time with respect to the Subordinated Notes by giving
written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 5.10 will not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning
Trustee may, at the Company’s expense, petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 (3)
The Trustee may be removed at any time with respect to the Subordinated Notes by Act of the Holders of a majority in principal amount of the Outstanding Subordinated Notes, delivered to the Trustee and the Company. 

If at any time: 
 (a) the
Trustee will fail to comply with the obligations imposed upon it under Section 310(b) of the Trust Indenture Act with respect to Subordinated Notes after written request therefor by the Company or any Holder who has been a bona fide Holder for
at least six months, 
 (b) the Trustee will cease to be eligible under Section 5.08 and will fail to resign after written request
therefor by the Company or any such Holder, or 
 (c) the Trustee will become incapable of acting or will be adjudged a bankrupt or
insolvent or a receiver of the Trustee or of its property will be appointed or any public officer will 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 Company, by or in accordance with a Board Resolution, may remove the Trustee with respect to the Subordinated Notes, or
(ii) subject to Section 315(e) of the Trust Indenture Act, any Holder who has been a bona fide Holder for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee with respect to all Subordinated Notes and the appointment of a successor Trustee or Trustees. 
 (4) If the Trustee
will resign, be removed or become incapable of acting, or if a vacancy will occur in the office of Trustee for any cause, with respect to the Subordinated Notes, the Company, by or in accordance with a Board Resolution, will promptly appoint a
successor Trustee or Trustees with respect to the Subordinated Notes and will comply with the applicable requirements of Section 5.10. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Subordinated Notes shall have been appointed by Act of the Holders of a majority in principal amount of the Outstanding Subordinated Notes delivered to the Company and the retiring Trustee, the successor Trustee
so appointed will, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 5.10, become the successor Trustee with respect to the Subordinated Notes and to that extent supersede the successor
Trustee appointed by the Company. If no successor Trustee with respect to the Subordinated Notes will have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 5.10, any Holder who has been
a bona fide Holder for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Subordinated Notes. 

  
 51 












 (5) The Company will give notice of each resignation and each removal of the Trustee with

5.10 Acceptance of Appointment by Successor. 

(1) Upon the appointment hereunder of any successor Trustee with respect to all Subordinated Notes, such successor Trustee so appointed will
execute, acknowledge and deliver to the Company and the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee will become effective and such successor Trustee, without any further
act, deed or conveyance, will become vested with all the rights, powers, trusts and duties hereunder of the retiring Trustee; but, on the request of the Company or such successor Trustee, such retiring Trustee, upon payment of its fees and expenses,
will execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and, subject to Section 9.03, will duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder, subject nevertheless to its claim, if any, provided for in Section 5.07. 
 (2) Upon
the appointment hereunder of any successor Trustee with respect to the Subordinated Notes, the Company, the retiring Trustee and such successor Trustee will execute and deliver an indenture supplemental hereto wherein each successor Trustee will
accept such appointment and which (i) will contain such provisions as will be necessary or desirable to transfer and confirm to, and to vest in, such successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with
respect to the Subordinated Notes, (ii) if the retiring Trustee is not retiring with respect to all Subordinated Notes, will contain such provisions as will be deemed necessary or desirable to confirm that all the rights, powers, trusts and
duties of the retiring Trustee with respect to the Subordinated Notes will continue to be vested in the retiring Trustee, and (iii) will add to or change any of the provisions of this Indenture as will be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture will constitute such Trustees co-trustees of the same trust, that
each such Trustee will be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee and that no Trustee will be responsible for any notice given to, or received by, or any act
or failure to act on the part of any other Trustee hereunder, and, upon the execution and delivery of such supplemental indenture, the resignation or removal of the retiring Trustee will become effective to the extent provided therein, such retiring
Trustee will have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture with respect to the Subordinated Notes other than as hereinafter
expressly set forth, and such successor Trustee, without any further act, deed or conveyance, will become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Subordinated Notes; but, on request of the
Company or such successor Trustee, such retiring Trustee, upon payment of 

  
 52 












 
its fees and expenses with respect to the Subordinated Notes and subject to Section 9.03 will duly assign, transfer and deliver to such successor Trustee, to the extent contemplated by such
supplemental indenture, the property and money held by such retiring Trustee hereunder with respect to the Subordinated Notes, subject to its claim, if any, provided for in Section 5.07. 

(3) Upon request of any Person appointed hereunder as a successor Trustee, the Company will execute any and all instruments for more fully and
certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (1) or (2) of this Section, as the case may be. 

(4) No Person will accept its appointment hereunder as a successor Trustee unless at the time of such acceptance such successor Person will be
qualified and eligible under this Article. No resigning or removed Trustee shall have any liability or responsibility for the action or inaction of any successor Trustee. 

5.11 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 will be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, will be the successor of the Trustee hereunder (provided that such
corporation will otherwise be 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 Subordinated Notes will have been authenticated but not
delivered by the Trustee then in office, any such successor to such authenticating Trustee may adopt such authentication and deliver the Subordinated Notes so authenticated with the same effect as if such successor Trustee had itself authenticated
such Subordinated Notes. In case any Subordinated Notes will not have been authenticated by such predecessor Trustee, any such successor Trustee may authenticate and deliver such Subordinated Notes in either its own name or that of its predecessor
Trustee. 
 5.12 Appointment of Authenticating Agent. 

The Trustee may appoint one or more Authenticating Agents acceptable to the Company with respect to the Subordinated Notes which will be
authorized to act on behalf of the Trustee to authenticate Subordinated Notes issued upon original issue, exchange, registration of transfer, partial redemption, partial repayment, or in accordance with Section 2.09, and Subordinated Notes so
authenticated will be entitled to the benefits of this Indenture and will 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
Subordinated Notes by the Trustee or the Trustee’s certificate of authentication, such reference will be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. 
 Each Authenticating Agent will be reasonably acceptable to the Company and,
except as provided in or under this Indenture, will at all times be a corporation that would be permitted by the Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act, is authorized under applicable law and
by its charter to act as an Authenticating Agent and 

  
 53 












 
has a combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000 and is subject to supervision or examination by federal
or state authority. If at any time an Authenticating Agent will cease to be eligible in accordance with the provisions of this Section, it will 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 will be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust business of an Authenticating Agent, will
be the successor of such Authenticating Agent hereunder, provided such corporation will 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 the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent will cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent that will be acceptable to the Company and will deliver written notice of such appointment by
first-class mail, postage prepaid, to all Holders with respect to which such Authenticating Agent will serve, as their names and addresses appear in the Subordinated Note Register. Any successor Authenticating Agent, upon acceptance of its
appointment hereunder, will 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 will be appointed unless eligible
under the provisions of this Section 5.12. 
 The Company agrees to pay each Authenticating Agent from time to time reasonable
compensation for its services under this Section. If the Trustee makes such payments, it will be entitled to be reimbursed for such payments, subject to the provisions of Section 5.07. 

The provisions of Section 2.11, Section 5.04 and Section 5.05 will be applicable to each Authenticating Agent. 

If an Authenticating Agent is appointed under this Section, the Subordinated Notes may have endorsed thereon, in addition to or in lieu of the
Trustee’s certificate of authentication, an alternate certificate of authentication in substantially the following form: 

  
 54 












 This is one of the Subordinated Notes of the series designated therein referred to in the

 9.01 Payment
of Principal and Interest. 
 The Company covenants and agrees for the benefit of the Holders that it will duly and punctually pay the
principal of, and interest on, the Subordinated Notes, in accordance with the terms thereof and this Indenture. Principal and interest will be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof,

If Additional Interest is payable by the Company in accordance with the Registration Rights Agreement, the Company will deliver to the Trustee

address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 

The Company may also from time to time designate one or more other offices or agencies where the Subordinated Notes may be presented or
surrendered for any or all such purposes and may from time to time rescind such designations; provided that no such designation or rescission will in any manner relieve the Company of its obligation to maintain an office or agency in the City of
Humble, Texas. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. 

The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with
Section 9.02; provided, however, that no service of legal process on the Company may be made at any office of the Trustee. 
 9.03
Money for Subordinated Notes Payments to Be Held in Trust. 
 If the Company will at any time act as its own Paying Agent, it will,
on or before each due date of the principal of, or interest on, any of the Subordinated Notes, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in Dollars sufficient to pay the principal and interest, as the case may
be, so becoming due until such sums will be paid to such Persons or otherwise disposed of as herein provided, and will promptly notify the Trustee of its action or failure so to act. 

Whenever the Company will have one or more Paying Agents, it will, on or prior to each due date of the principal of, or interest on, any
Subordinated Notes, deposit with any Paying Agent a sum in Dollars sufficient to pay the principal and interest, as the case may be, so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
 The Company will cause each
Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent will 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, or interest on, the Subordinated Notes in trust for the benefit of the
Persons entitled thereto until such sums will be paid to such Persons or otherwise disposed of as provided in or under this Indenture; 

(2) give the Trustee notice of any default by the Company in the making of any payment of principal, or interest on, the Subordinated Notes;
and 
 (3) at any time during the continuance of any such default, upon the written request of the Trustee, pay to the Trustee all sums so
held in trust by such Paying Agent. 

  
 62 












 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of
this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same terms as those upon which
such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent will be released from all further liability with respect to such sums. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of, or
interest on, any Subordinated Note and remaining unclaimed for two years after such principal or interest will have become due and payable will be paid to the Company upon a Company Request, or (if then held by the Company) will be discharged from
such trust; and the Holder of such Subordinated Note will thereafter, as an unsecured general creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, will thereupon cease. 
 9.04 Corporate Existence. 

Subject to Article VII, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect
(i) the corporate existence of the Company, (ii) the existence (corporate or other) of each Significant Subsidiary and (iii) the rights (charter and statutory), licenses and franchises of the Company and each of its Significant
Subsidiaries, including without limitation the Company’s status as a bank holding company or financial holding company under the Bank Holding Company Act of 1956, as amended, and the Bank’s status as an “insured depository
institution” under Section 3(c)(2) of the Federal Deposit Insurance Act, as amended; provided, however, that the Company will not be required to preserve the existence (corporate or other) of any of its Significant Subsidiaries or any such
right, license or franchise of the Company or any of its Significant Subsidiaries if the Board of Directors of the Company determines that the preservation thereof is no longer desirable in the conduct of the business of the Company and its
Significant Subsidiaries taken as a whole and that the loss thereof will not be disadvantageous in any material respect to the Holders. Subject to Article VII, the Company shall not take any action, omit to take any action or enter into any
transaction that would have the effect of the Company owning less than one hundred percent (100%) of the capital stock of the Bank. 
 9.05
Maintenance of Properties. 
 The Company will, and will cause each Significant Subsidiary to, cause all its properties used or
useful in the conduct of its business to be maintained and kept in good condition, repair and working order and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and
improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this Section will
prevent the Company or any Significant Subsidiary from discontinuing the operation and maintenance of any of their respective properties if such discontinuance is, in the judgment of the Board of Directors of the Company or of any Significant
Subsidiary, as the case may be desirable in the conduct of its business.

 9.06 Waiver of Certain Covenants. 

The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 9.02 to
Section 9.05, inclusive, with respect to the Subordinated Notes if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Subordinated Notes, by Act of such Holders, either will waive such
compliance in such instance or generally will have waived compliance with such term, provision or condition, but no such waiver will extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such
waiver will become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition will remain in full force and effect. 

9.07 Company Statement as to Compliance. 

The Company will deliver to the Trustee, within 120 days after the end of each fiscal year, an Officers’ Certificate covering the
preceding calendar year, stating whether or not, to the best of his or her knowledge, the Company is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to notice requirements
or periods of grace) and if the Company will be in default, specifying all such defaults and the nature and status thereof of which he or she may have knowledge. 

9.08 Tier 2 Capital. 
 If
all or any portion of the Subordinated Notes ceases to be deemed to be Tier 2 Capital, other than due to the limitation imposed on the capital treatment of subordinated debt during the five (5) years immediately preceding the maturity date of
the Subordinated Notes, the Company will immediately notify the Trustee and the Holders thereof, and thereafter the Company and the Holders will work together in good faith, subject to the terms of this Indenture, to execute and deliver all
agreements as reasonably necessary in order to restructure the applicable portions of the obligations evidenced by the Subordinated Notes to qualify as Tier 2 Capital and the Company shall request, subject to the terms of this Indenture, that the
Trustee execute and deliver all such agreements as may be reasonably necessary in order to effect any restructuring agreed to by the Company and the Holders; provided, however, that nothing contained in this Section 9.08 shall limit the
Company’s right to redeem the Subordinated Notes upon the occurrence of a Tier 2 Capital Event pursuant to Section 10.01(3) hereof. 

ARTICLE X 
 REDEMPTION OF
SECURITIES 
 10.01 Applicability of Article. 

(1) Except as provided in this Section 10.01, the Subordinated Notes are not subject to redemption at the option of the Company. The
Subordinated Notes are not subject to redemption at the option of the Holders. 
 (2) Subject to the receipt of any required regulatory
approvals, including but not limited to the prior approval of the Federal Reserve, to the extent such approval is then required under the capital adequacy rules of the Federal Reserve System, with corresponding notice to the Trustee, the Company
may, at its option, on any Interest Payment Date on or after April 1, 2027, redeem all or a portion of the Subordinated Notes. 

  
 64 












 (3) Subject to the receipt of any required regulatory approvals, including but not limited
to the prior approval of the Federal Reserve, to the extent such approval is then required under the capital adequacy rules of the Federal Reserve System, with corresponding notice to the Trustee, the Company may, at its option, redeem all, but not
a portion, of the Outstanding Subordinated Notes at any time upon a Tier 2 Capital Event, a Tax Event or an Investment Company Event. 
 (4)
The Redemption Price with respect to any redemption permitted under this Indenture will be equal to 100% of the principal amount of the Subordinated Notes to be redeemed, plus accrued but unpaid interest and Additional Interest, if any, thereon to,
but excluding, the Redemption Date. 
 10.02 Election to Redeem; Notice to Trustee. 

The election of the Company to redeem any Subordinated Notes will be evidenced by a Company Order. In case of any redemption of less than all
of the Subordinated Notes, the Company will, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice will be satisfactory to the Trustee, but in any event not less than 45 days prior to the Redemption Date),
notify the Trustee, of such Redemption Date and of the principal amount of Subordinated Notes to be redeemed. 
 In the case of any
redemption of Subordinated Notes (i) prior to the expiration of any restriction on such redemption provided in the terms of such Subordinated Notes or elsewhere in this Indenture or (ii) in accordance with an election of the Company that
is subject to a condition specified in the terms of such Subordinated Notes or elsewhere in this Indenture, the Company will furnish to the Trustee an Officers’ Certificate evidencing compliance with such restriction or condition. 

10.03 Selection by Trustee of Subordinated Notes to be Redeemed. 

If less than all of the Subordinated Notes are to be redeemed, the particular Subordinated Notes to be redeemed will be selected not
more than 45 days prior to the Redemption Date by the Trustee from the Outstanding Subordinated Notes not previously called for redemption unless otherwise required by law or applicable depositary requirements, on a pro rata basis; provided,
however, that no such partial redemption will reduce the portion of the principal amount of a Subordinated Note not redeemed to less than the minimum denomination for a Subordinated Note established in or under this Indenture. Any partial redemption
will be processed thru DTC, in accordance with its rules and procedures as a “Pro Rata Pass-Through Distribution of Principal.” In the event a pro rata redemption is not permitted under applicable law or applicable depositary requirements,
the Subordinated Notes to be redeemed will be selected by lot or such method as the Trustee will deem fair and appropriate. 
 The Trustee
will promptly notify the Company and the Registrar (if other than itself) in writing of the Subordinated Notes selected for redemption and, in the case of any Subordinated Notes selected for partial redemption, the principal amount thereof to be
redeemed. 

  
 65 












 For all purposes of this Indenture, unless the context otherwise requires, all provisions
relating to the redemption of Subordinated Notes will relate, in the case of any Subordinated Notes redeemed or to be redeemed only in part, to the portion of the principal of such Subordinated Notes which has been or is to be redeemed. 

10.04 Notice of Redemption. 

Notice of redemption will be given in the manner provided in Section 1.05, not less than 30 nor more than 60 days prior to the Redemption
Date to the Holders of Subordinated Notes to be redeemed. Failure to give notice by delivering in the manner herein provided to the Holder of any Subordinated Notes designated for redemption as a whole or in part, or any defect in the notice to any
such Holder, will not affect the validity of the proceedings for the redemption of any other Subordinated Notes or portions thereof. 
 Any
notice that is delivered to the Holder of any Subordinated Notes in the manner herein provided will be conclusively presumed to have been duly given, whether or not such Holder receives the notice. 

All notices of redemption will state: 

(1) the Redemption Date, 
 (2)
the Redemption Price, 
 (3) if less than all Outstanding Subordinated Notes are to be redeemed, the identification (and, in the case of
partial redemption, the principal amount) of the particular Subordinated Note or Subordinated Notes to be redeemed, 
 (4) that, in case any
Subordinated Note is to be redeemed in part only, on and after the Redemption Date, upon surrender of such Subordinated Note, the Holder of such Subordinated Note will receive, without charge, a new Subordinated Note or Subordinated Notes of
authorized denominations for the principal amount thereof remaining unredeemed, 
 (5) that, on the Redemption Date, the Redemption Price
will become due and payable upon each such Subordinated Note or portion thereof to be redeemed, together (if applicable) with accrued and unpaid interest and Additional Interest, if any, thereon (subject, if applicable, to the provisos to the first
paragraph of Section 10.06), and, if applicable, that interest thereon will cease to accrue on and after said date, 
 (6) the place or
places where such Subordinated Notes are to be surrendered for payment of the Redemption Price and any accrued interest pertaining thereto, and 

(7) the section hereunder providing for such redemption. 

The notice of redemption shall include the CUSIP number reference numbers of such Subordinated Notes, if any (or any other numbers used by a
Depositary to identify such Subordinated Notes). 

  
 66 












 Notice of redemption of Subordinated Notes to be redeemed at the election of the Company
will be given by the Company or, at the Company’s request delivered at least 10 days before the date such notice is to be given (unless a shorter period will be acceptable to the Trustee) together with the form of notice to be delivered, by the
Trustee in the name and at the expense of the Company. 
 10.05 Deposit of Redemption Price. 

On or prior to 11:00 am., Houston, Texas time, on any Redemption Date, the Company will deposit, with respect to the Subordinated Notes called
for redemption in accordance with Section 10.04, with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 9.03) an amount sufficient to pay the
Redemption Price of, and (except if the Redemption Date will be an Interest Payment Date) any accrued interest on, all such Subordinated Notes or portions thereof which are to be redeemed on that date. 

10.06 Subordinated Notes Payable on Redemption Date. 

Notice of redemption having been given as provided above, the Subordinated Notes so to be redeemed will, on the Redemption Date, become due
and payable at the Redemption Price therein specified, together with accrued and unpaid interest and Additional Interest, if any, thereon and from and after such date (unless the Company will default in the payment of the Redemption Price and
accrued interest, if any) such Subordinated Notes will cease to bear interest. Upon surrender of any such Subordinated Note for redemption in accordance with said notice, such Subordinated Note will be paid by the Company at the Redemption Price,
together with any accrued and unpaid interest and Additional Interest, if any, thereon to but excluding the Redemption Date; provided, however, that installments of interest on Subordinated Notes whose Stated Maturity is on or prior to the
Redemption Date will be payable to the Holders of such Subordinated Notes registered as such at the close of business on the Regular Record Dates therefor according to their terms and the provisions of Section 2.10. 

If any Subordinated Note called for redemption will not be so paid upon surrender thereof for redemption, the principal, until paid, will bear
interest from the Redemption Date at the rate prescribed therefor in the Subordinated Note or, if no rate is prescribed therefor in the Subordinated Note, at the rate of interest, if any, borne by such Subordinated Note. 

10.07 Subordinated Notes Redeemed in Part. 

Any Subordinated Note which is to be redeemed only in part will be surrendered at any office or agency for such Subordinated Note (with, if
the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company will
execute and the Trustee will authenticate and deliver to the Holder of such Subordinated Note without service charge, a new Subordinated Note or Subordinated Notes, containing identical terms and provisions, of any authorized denomination as
requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Subordinated Note so surrendered. If a Global Subordinated Note is so


  
 67 












 
surrendered, the Company will execute, and the Trustee will authenticate and deliver to the Depositary for such Global Subordinated Note as will be specified in the Company Order with respect
thereto to the Trustee, without service charge, a new Global Subordinated Note in a denomination equal to and in exchange for the unredeemed portion of the principal of the Global Subordinated Note so surrendered. 

Upon surrender of a Subordinated Note that is redeemed in part, the Company will issue and the Trustee will authenticate for the Holder at the
expense of the Company a new Subordinated Note equal in principal amount to the unredeemed portion of the Subordinated Note surrendered representing the same indebtedness to the extent not redeemed. Notwithstanding anything in this Indenture to the
contrary, only a Company Order and not an Opinion of Counsel or an Officers’ Certificate of the Company is required for the Trustee to authenticate such new Subordinated Note. 

ARTICLE XI 

SUBORDINATION OF SECURITIES 

11.01 Agreement to Subordinate. 

The Company, for itself, its successors and assigns, covenants and agrees, and each Holder of Subordinated Notes by the Holder’s
acceptance thereof, likewise covenants and agrees, that the payment of the principal of and interest on each and all of the Subordinated Notes is and will be expressly subordinated in right of payment to the prior payment in full of all Senior
Indebtedness. 
 11.02 Distribution of Assets. 

(1) Upon any distribution of assets of the Company upon any termination, winding up, liquidation or reorganization of the Company, whether in
bankruptcy, insolvency, reorganization or receivership proceedings or upon an assignment for the benefit of creditors or any other marshalling of the assets and liabilities of the Company or otherwise (subject to the power of a court of competent
jurisdiction to make other equitable provision reflecting the rights conferred upon the Senior Indebtedness and the holders thereof with respect to the Subordinated Notes and the Holders thereof by a lawful plan of reorganization under applicable
bankruptcy law): 
 (a) holders of all Senior Indebtedness will first be entitled to receive payment in full in accordance with the
terms of such Senior Indebtedness of the principal thereof, premium, if any, and the interest due thereon (including interest accruing subsequent to the commencement of any proceeding for the bankruptcy or reorganization of the Company under any
applicable bankruptcy, insolvency or similar law now or hereafter in effect) before the Holders of the Subordinated Notes are entitled to receive any payment upon the principal of or interest on indebtedness evidenced by the Subordinated Notes; 

(b) any payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the
Holders would be entitled except for the provisions of this Article XI, including any such payment or distribution that may be payable or deliverable by reason of the payment of any other indebtedness of the Company being subordinated to the payment
of the Subordinated Notes, will be paid by the liquidating trustee or agent or other Person making such payment or distribution, whether a trustee in bankruptcy, a receiver or liquidating trustee or otherwise, directly to the holders of Senior
Indebtedness or their 

  
 68 












 
representative or representatives or to the trustee or trustees under any indenture under which any instruments evidencing any of such Senior Indebtedness may have been issued, in accordance with
the priorities then existing among holders of Senior Indebtedness for payment of the aggregate amounts remaining unpaid on account of the principal, premium, if any, and interest (including interest accruing subsequent to the commencement of any
proceeding for the bankruptcy or reorganization of the Company under any applicable bankruptcy, insolvency or similar law now or hereafter in effect) on the Senior Indebtedness held or represented by each, to the extent necessary to make payment in
full of all Senior Indebtedness remaining unpaid, after giving effect to any concurrent payment or distribution to the holders of such Senior Indebtedness; it being understood that if the Holders fail to file a proper claim in the form required by
any proceeding referred to in this Section 11.02(1)(b) prior to 30 days before the expiration of the time to file such claim or claims, then the holders of Senior Indebtedness are hereby authorized to file an appropriate claim or claims for and
on behalf of the Holders, in the form required in any such proceeding; and 
 (c) in the event that, notwithstanding the foregoing, any
payment or distribution of assets of the Company of any kind or character, whether in cash, property or securities, including any such payment or distribution that may be payable or deliverable by reason of the payment of any other indebtedness of
the Company being subordinate to the payment of the Subordinated Notes will be received by the Trustee or the Holders before all Senior Indebtedness is paid in full, such payment or distribution will be paid over to the trustee in bankruptcy,
receiver, liquidating trustee, custodian, assignee, agent or other Person making payment of assets of the Company for all Senior Indebtedness remaining unpaid until all such Senior Indebtedness will have been paid in full, after giving effect to any
concurrent payment or distribution to the holders of such Senior Indebtedness, 
 (2) Subject to the payment in full of all Senior
Indebtedness, the Holders will be subrogated to the rights of the holders of Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company applicable to the Senior Indebtedness until the principal of and
interest on the Subordinated Notes will be paid in full and no such payments or distributions to holders of such Senior Indebtedness to which the Holders would be entitled except for the provisions hereof of cash, property or securities otherwise
distributable to the holders of Senior Indebtedness will, as between the Company, its creditors, other than the holders of Senior Indebtedness, and the Holders, be deemed to be a payment by the Company to or on account of the Senior Indebtedness. It
is understood that the provisions of this Article XI are intended solely for the purpose of defining the relative rights of the Holders of the Subordinated Notes, on the one hand, and the holders of Senior Indebtedness, on the other hand. Nothing
contained in this Article XI or elsewhere in this Indenture or any supplemental indenture issued in accordance with Article VIII of this Indenture or in the Subordinated Notes is intended to or will impair, as between the Company, its creditors,
other than the holders of Senior Indebtedness, and the Holders, the obligation of the Company, which is unconditional and absolute, to pay to the Holders the principal of and interest on the Subordinated Notes as and when the same will become
due and payable in accordance with their terms or to affect the relative rights of the Holders and creditors of the Company, other than the holders of the Senior Indebtedness, nor, except as otherwise expressly provided in this Indenture and the
Subordinated Notes with respect to the limitation on the rights of the Trustee and the Holders, to accelerate the maturity of the Subordinated Notes and pursue remedies upon such an acceleration, will anything herein or in the


  
 69 












 
Subordinated Notes prevent the Trustee or any Holder from exercising all remedies otherwise permitted by applicable law upon any Event of Default under the Indenture occurring, subject to the
rights, if any, under this Article XI of the holders of Senior Indebtedness, in respect of cash, property or securities of the Company received upon the exercise of any such remedy. Upon any payment or distribution of assets of the Company referred
to in this Article XI, the Trustee and the Holders will be entitled to conclusively rely upon any order or decree of a court of competent jurisdiction in which such termination, winding up, liquidation or reorganization proceeding is pending or upon
a certificate of the liquidating trustee or agent or other Person making any distribution to the Trustee or to the Holders for the purpose of ascertaining the Persons entitled to participate in such distribution, the holders of the Senior
Indebtedness and other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XI. In the absence of any such liquidating trustee,
agent or other person, the Trustee will be entitled to rely upon a written notice by a Person representing itself to be a holder of Senior Indebtedness (or a trustee or representative on behalf of such holder) as evidence that such Person is a
holder of Senior Indebtedness (or is such a trustee or representative). If the Trustee determines, in good faith, that further evidence is required with respect to the right of any Person, as a holder of Senior Indebtedness, to participate in any
payment or distribution in accordance with this Article XI, 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, as to the extent to which
such Person is entitled to participation in such payment or distribution, and as to other facts pertinent to the rights of such Person under this Article XI, 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. 
 With respect to the holders of Senior
Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Indenture, and no implied covenants or obligations with respect to the holders of Senior Indebtedness will
be read into this Indenture against the Trustee. The Trustee, however, will not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness by reason of the execution of this Indenture, or any other supplemental indenture entered into
in accordance with Article VIII of this Indenture, and will not be liable to any such holders if it will in good faith mistakenly pay over or distribute to or on behalf of the Holders or the Company moneys or assets to which any holders of Senior
Indebtedness will be entitled by virtue of this Article XI or otherwise. 
 11.03 Default With Respect to Senior Indebtedness. 

In the event and during the continuation of any default in the payment of principal of, or premium, if any, or interest on, any Senior
Indebtedness, beyond any applicable grace period, or if any event of default with respect to any Senior Indebtedness will have occurred and be continuing, or would occur as a result of the payment referred to hereinafter, permitting the holders of
such Senior Indebtedness (or a trustee on behalf of the holders thereof) to accelerate the maturity thereof, then, unless and until such default or event of default will have been cured or waived or will have ceased to exist, no payment or principal
of or interest on the Subordinated Notes, or in respect of any retirement, purchase or other acquisition of any of the Subordinated Notes, will be made by the Company. 

  
 70 












 11.04 No Impairment. 

Nothing contained in this Indenture, any other supplemental indenture entered into in accordance with Article VIII of this Indenture, or in
any of the Subordinated Notes will: (i) impair, as between the Company and the Holders, the obligations of the Company to make, or prevent the Company from making, at any time except as provided in Section 11.02 and Section 11.03,
payments of principal of, or interest (including interest accruing subsequent to the commencement of any proceeding for the bankruptcy or reorganization of the Company under any applicable bankruptcy, insolvency, or similar law now or hereafter in
effect) on, the Subordinated Notes, as and when the same will become due and payable in accordance with the terms of the Subordinated Notes; (ii) affect the relative rights of the Holders and creditors of the Company other than the holders of
the Senior Indebtedness; (iii) except as otherwise expressly provided in this Indenture and the Subordinated Notes with respect to the limitation on the rights of the Trustee and the Holders, to accelerate the maturity of the Subordinated Notes
and pursue remedies upon such an acceleration, prevent the Holder of any Subordinated Notes or the Trustee from exercising all remedies otherwise permitted by applicable law upon default thereunder, subject to the rights, if any, under this Article
XI of the holders of Senior Indebtedness in respect of cash, property or securities of the Company received upon the exercise of such remedy; or (iv) prevent the application by the Trustee or any Paying Agent of any moneys deposited with it
hereunder to the payment of or on account of the principal of, or interest on, the Subordinated Notes or prevent the receipt by the Trustee or any Paying Agent of such moneys, if, prior to the third Business Day prior to such deposit, the Trustee or
such Paying Agent did not have written notice of any event prohibiting the making of such deposit by the Company. 
 11.05 Effectuation
of Subordination Provisions. 
 Each Holder by his acceptance of any Notes authorizes and expressly directs the Trustee on such
Holder’s behalf to take such action as may be necessary or appropriate to effectuate the Subordination Provisions, and appoints the Trustee such Holder’s
attorney-in-fact for such purposes, including, in the event of any termination, winding up, liquidation or reorganization of the Company (whether in bankruptcy,
insolvency, receivership, reorganization or similar proceedings or upon an assignment for the benefit of creditors by the Company, a marshalling of the assets and liabilities of the Company or otherwise) tending toward the liquidation of the
property and assets of the Company, the filing of a claim for the unpaid balance of the Subordinated Notes in the form required in those proceedings. 

11.06 Notice to Trustee. 

The Company will give prompt written notice to the Trustee of any fact known to the Company that would prohibit the Company from making any
payment to or by the Trustee in respect of the Subordinated Notes in accordance with the provisions of this Article XI. The Trustee will not be charged with the knowledge of the existence of any default or event of default with respect to any Senior
Indebtedness or of any other facts that would prohibit the making of any payment to or by the Trustee or any Paying Agent unless and until a Responsible Officer of the Trustee has received a written notice specifying such default, event of default
or other facts signed by an Authorized Officer, or by a holder of Senior Indebtedness or a trustee or agent thereof; and prior to the receipt of any such written notice, the Trustee will, subject to Article V of this


  
 71 












 
Indenture, be entitled to assume that no such facts exist; provided that, if the Trustee will not have received the notice provided for in this Section 11.06 at least two Business Days prior
to the date upon which, by the terms of the Indenture, any monies will become payable for any purpose (including, without limitation, the payment of the principal of or interest on any Subordinated Note), then, notwithstanding anything herein to the
contrary, the Trustee will have full power and authority to receive any monies from the Company and to apply the same to the purpose for which they were received, and will not be affected by any notice to the contrary that may be received by it on
or after such prior date except for an acceleration of the Subordinated Notes prior to such application. The foregoing will not apply if the Paying Agent is the Company. The Trustee will be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself or itself to be a holder of any Senior Indebtedness (or a trustee on behalf of, or agent of, such holder) to establish that such notice has been given by a holder of such Senior Indebtedness or a
trustee or agent on behalf of any such holder. 
 In the event that the Trustee determines in good faith that any evidence is required with
respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution in accordance with this Article XI, 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 XI and, if
such evidence is not furnished to the Trustee, the Trustee may defer any payment to such Person pending such evidence being furnished to the Trustee or a judicial determination that such Person has the right to receive such payment. 

11.07 Trustee Knowledge of Senior Indebtedness. 

Notwithstanding the provisions of this Article XI or any other provisions of this Indenture or any other supplemental indenture issued in
accordance with Article VIII of this Indenture, neither the Trustee nor any Paying Agent will be charged with knowledge of the existence of any Senior Indebtedness or of any event that would prohibit the making of any payment of moneys to or by the
Trustee or such Paying Agent, unless and until a Responsible Officer of the Trustee or such Paying Agent will have received written notice thereof from the Company or from the holder of any Senior Indebtedness or from the representative of any such
holder. 
 11.08 Senior Indebtedness to Trustee. 

The Trustee will be entitled to all of the rights set forth in this Article XI in respect of any Senior Indebtedness at any time held by it in
its individual capacity to the same extent as any other holder of such Senior Indebtedness, and nothing in this Indenture or any other supplemental indenture issued in accordance with Article VIII of this Indenture will be construed to deprive the
Trustee of any of its rights as such holder. 
 11.09 Subordination Not Applicable to Trustee Compensation. 

Nothing contained in this Article XI will apply to the claims of, or payments to, the Trustee under Section 5.07 of this Indenture. 

  
 72 












 The Trustee hereby accepts the trusts in this Indenture upon the terms and conditions set
forth herein.

(the “Subordinated Notes”) in an aggregate principal amount of $82,250,000 and initially issued on March 31, 2022. The Company has issued this Subordinated Note under that certain Indenture dated as of March 31, 2022, as the same
may be amended or supplemented from time to time (“Indenture”), between the Company and UMB Bank, National Association, as Trustee (the “Trustee”). All capitalized terms not otherwise defined in this Subordinated Note will
have the meanings assigned to them in the Indenture. The terms of this Subordinated Note include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust
Indenture Act”). This Subordinated Note is subject to all such terms, and the Holder (as defined below) is referred to the Indenture and the Trust Indenture Act for a statement of such terms. To the extent any provision of this Subordinated
Note irreconcilably conflicts with the express provisions of the Indenture, the provisions of the Indenture will govern and be controlling. 

2. Payment. The Company, for value received, promises to pay to [•], or its registered assigns (the “Holder”), the
principal sum of [•] MILLION DOLLARS (U.S.) ($[•]), plus accrued but unpaid interest on April 1, 2032 (the “Stated Maturity Date”), unless redeemed prior to such date, and to
pay interest thereon (i) from, and including, March 31, 2022, to, but excluding, April 1, 2027, unless redeemed prior to such date, at a rate of 5.500% per annum, semi-annually in arrears on April 1 and October 1 of each
year, commencing October 1, 2022 (each such date, a “Fixed Rate Interest Payment Date,” with the period from, and including, March 31, 2022 to, but excluding, the first Fixed Rate Interest Payment Date and each successive period
from, and including, a Fixed Rate Interest Payment Date to, but excluding, the next Fixed Rate Interest Payment Date being a “Fixed Rate Period”), and (ii) from, and including, April 1, 2027 to, but excluding, the Stated Maturity
Date, unless redeemed prior to the Stated Maturity Date, at a rate equal to Three-Month Term SOFR, reset quarterly, plus 315 basis points, or such other rate as determined pursuant to the Indenture, payable quarterly in arrears on January 1,
April 1, July 1 and October 1 of each year through the Stated Maturity Date or earlier Redemption Date (each, a “Floating Rate Interest Payment Date” and, together with the Fixed Rate Interest Payment Dates, the
“Interest Payment Dates,” with the period from, and including, April 1, 2027 to, but excluding, the first Floating Rate Interest Payment Date and each successive period from, and including a Floating Rate Interest Payment Date to, but
excluding, the next Floating Rate Interest Payment Date being a “Floating Rate Period”). The amount of interest payable on any Fixed Rate Interest Payment Date during the Fixed Rate Period will be computed on the basis of a 360-day year consisting of twelve 30-day months up to, but excluding April 1, 2027, and, the amount of interest payable on any Floating Rate Interest Payment Date
during the Floating Rate Period will be computed on the basis of a 360-day year and the number of days actually elapsed. In the event that any scheduled Interest Payment Date for this Subordinated Note falls
on a day that is not a Business 

  
 A-1-1 












 
Day, then payment of interest payable on such Interest Payment Date will be paid on the next succeeding day which is a Business Day (any payment made on such date will be treated as being made on
the date that the payment was first due and no interest on such payment will accrue for the period from and after such scheduled Interest Payment Date); provided, that in the event that any scheduled Floating Rate Interest Payment Date falls on a
day that is not a Business Day and the next succeeding Business Day falls in the next succeeding calendar month, such Floating Rate Interest Payment Date will be accelerated to the immediately preceding Business Day, and, in each such case, the
amounts payable on such Business Day will include interest accrued to, but excluding, such Business Day. All percentages used in or resulting from any calculation of Three-Month Term SOFR shall be rounded, if necessary, to the nearest one
hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%. The Company will pay all Additional Interest (as defined in the Indenture), if any, on the dates and in the amounts set forth in the Registration Rights Agreement (as
defined in the Indenture). 
 The Company will pay interest on this Subordinated Note to the Person who is the registered Holder at the
close of business on the fifteenth day (whether or not a Business Day) prior to the applicable Interest Payment Date, except as provided in Section 2.10 of the Indenture with respect to Defaulted Interest. This Subordinated Note will be payable
as to principal and interest at the office or agency of the Paying Agent, or, at the option of the Company, payment of interest may be made by check delivered to the Holder at its address set forth in the Subordinated Note Register or by wire
transfer to an account appropriately designated by the Person entitled to payment; provided, that the Paying Agent will have received written notice of such account designation at least five Business Days prior to the date of such payment
(subject to surrender of this Subordinated Note in the case of a payment of interest at Stated Maturity). 
 3. Paying Agent and
Registrar. The Trustee, as Trustee under the Indenture, will act as the initial Paying Agent and Registrar through its offices presently located at 5555 San Felipe Street, Suite 870, Houston, Texas 77056. The Company may change any Paying Agent
or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 
 4. Subordination.
The indebtedness of the Company evidenced by this Subordinated Note, including the principal thereof and interest thereon, is, to the extent and in the manner set forth in the Indenture, subordinate and junior in right of payment to obligations of
the Company constituting the Senior Indebtedness (as defined in the Indenture) on the terms and subject to the terms and conditions as provided and set forth in Article XI of the Indenture and will rank pari passu in right of payment with all
other Subordinated Notes. Holder, by the acceptance of this Subordinated Note, agrees to and will be bound by such provisions of the Indenture and authorizes and directs the Trustee on his behalf to take such actions as may be necessary or
appropriate to effectuate the subordination so provided. 

  
 A-1-2 












 5. Redemption. 

a. The Company may, at its option, on any Interest Payment Date on or after April 1, 2027, redeem this Subordinated Note, in whole or in
part, without premium or penalty, but in all cases in a principal amount with integral multiples of $1,000. In addition, the Company may, at its option, redeem all, but not a portion of the Subordinated Notes, at any time upon the occurrence of a
Tier 2 Capital Event, a Tax Event or an Investment Company Event. Any redemption of this Subordinated Note shall be subject to the prior approval of the Federal Reserve (or its designee) or any successor agency, and any other bank regulatory agency,
to the extent such approval shall then be required by law, regulation or policy. This Subordinated Note is not subject to redemption at the option of the Holder. The Redemption Price with respect to any redemption permitted under the Indenture will
be equal to 100% of the principal amount of this Subordinated Note, or portion thereof, to be redeemed, plus accrued but unpaid interest and Additional Interest, if any, thereon to, but excluding, the Redemption Date. 

b. If less than the then outstanding principal amount of this Subordinated Note is redeemed, (i) a new note shall be issued representing
the unredeemed portion without charge to the Holder thereof and (ii) such redemption shall be effected on a pro rata basis as to the Holders. For purposes of clarity, upon a partial redemption, a like percentage of the principal amount of every
Subordinated Note held by every Holder shall be redeemed. 
 c. If notice of redemption has been duly given and notwithstanding that any
Subordinated Notes so called for redemption have not been surrendered for cancellation, on and after the Redemption Date interest shall cease to accrue on all Subordinated Notes so called for redemption, all Subordinated Notes so called for
redemption shall no longer be deemed outstanding and all rights with respect to such Subordinated Notes shall forthwith on such Redemption Date cease and terminate (unless the Company shall default in the payment of the redemption price), except
only the right of the Holder thereof to receive the amount payable on such redemption, without interest. 
 6. Events of Default;
Acceleration. An “Event of Default” means any one of the events described in Section 4.01 of the Indenture. If an Event of Default described in Section 4.01(1) or 4.01(2) of the Indenture occurs, then the principal amount of
all of the Outstanding Subordinated Notes, and accrued and unpaid interest, if any, on all Outstanding Subordinated Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or the Holder,
and the Company waives demand, presentment for payment, notice of nonpayment, notice of protest, and all other notices. Notwithstanding the foregoing, upon the occurrence of an Event of Default other than an Event of Default described in
Section 4.01(1) or 4.01(2) of the Indenture, neither the Trustee nor the Holder may accelerate the Stated Maturity of the Subordinated Notes and make the principal of, and any accrued and unpaid interest on the Subordinated Notes, immediately
due and payable. If any Event of Default occurs and is continuing, the Trustee may also pursue any other available remedy to collect the payment of principal of, and interest on, the Subordinated Notes then due and payable or to enforce the
performance of any provision of the Subordinated Notes or the Indenture. 
 7. Failure to Make Payments. If the Company fails to make
any payment of interest on this Subordinated Note when such interest becomes due and payable and such default continues for a period of 30 days, or if the Company fails to make any payment of the principal of this Subordinated Note when such
principal becomes due and payable, the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holder, the whole amount then due and payable with respect to this Subordinated Note, with interest upon the overdue
principal, any premium and, to the extent permitted by applicable law, upon any overdue installments of interest at the rate or respective rates, as the case may be, provided for or with respect to this Subordinated Note or, if no such rate or rates
are so provided, at the rate or respective rates, as the case may be, of interest borne by this Subordinated Note. 

  
 A-1-3 












 Upon an Event of Default, the Company may not declare or pay any dividends or distributions
on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Company’s capital stock, make any payment of principal or interest or premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank equal with or junior to this Subordinated Note, or make any payments under any guarantee that ranks equal with or junior to this Subordinated Note, other than: (i) any dividends or distributions in shares of, or options,
warrants or rights to subscribe for or purchase shares of, any class of the Company’s common stock; (ii) any declaration of a dividend in connection with the implementation of a shareholders’ rights plan, or the issuance of stock
under any such plan in the future, or the redemption or repurchase of any such rights pursuant thereto; (iii) as a result of a reclassification of the Company’s capital stock or the exchange or conversion of one class or series of the
Company’s capital stock for another class or series of the Company’s capital stock; (iv) the purchase of fractional interests in shares of the Company’s capital stock in accordance with the conversion or exchange provisions of
such capital stock or the security being converted or exchanged; or (v) purchases of any class of the Company’s common stock related to the issuance of common stock or rights under any benefit plans for the Company’s directors,
officers or employees or any of the Company’s dividend reinvestment plans. 
 8. Denominations, Transfer, Exchange. The
Subordinated Notes are issuable only in registered form without interest coupons in minimum denominations of $100,000 and integral multiples of $1,000 in excess thereof. The transfer of this Subordinated Note may be registered and this Subordinated
Note may be exchanged as provided in the Indenture. The Registrar may require the Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require the Holder to pay any taxes and fees required by law
or permitted by the Indenture. 
 9. Charges and Transfer Taxes. No service charge will be made for any registration of transfer or
exchange of this Subordinated Note, or any redemption or repayment of this Subordinated Note, or any conversion or exchange of this Subordinated Note for other types of securities or property, but the Company may require payment of a sum sufficient
to pay all taxes, assessments or other governmental charges that may be imposed in connection with the transfer or exchange of this Subordinated Note from the Holder requesting such transfer or exchange. 

10. Persons Deemed Owners. The Company and the Trustee and any agent of the Company or the Trustee may treat the Person in whose name
this Subordinated Note is registered as the owner hereof for all purposes, whether or not this Subordinated Note is overdue, and neither the Company, the Trustee nor any such agent will be affected by notice to the contrary. 

11. Amendments; Waivers. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification
of the rights and obligations of the Company and the rights of the Holders of the Subordinated Notes at any time by the Company and the Trustee with the consent of the holders of a majority in principal amount of the then Outstanding Subordinated

of the holders of all Subordinated Notes, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Subordinated Note will be
conclusive and binding upon such Holder and upon all future holders of this Subordinated Note and of any Subordinated Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Subordinated Note. 
 12. No Impairment. No reference herein to the Indenture and no provision of
this Subordinated Note or of the Indenture will alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest (if any) and Additional Interest on this Subordinated Note at the times, place
and rate as herein prescribed. 
 13. No Sinking Fund; No Convertibility. This Subordinated Note is not entitled to the benefit of

in arrears on April 1 and October 1 of each year, commencing October 1, 2022 (each such date, a “Fixed Rate Interest Payment Date,” with the period from, and including, March 31, 2022 to, but excluding, the first Fixed
Rate Interest Payment Date and each successive period from, and including, a Fixed Rate Interest Payment Date to, but excluding, the next Fixed Rate Interest Payment Date being a “Fixed Rate Period”), and (ii) from, and including,
April 1, 2027 to, but excluding, the Stated Maturity Date, unless redeemed prior to the Stated Maturity Date, at a rate equal to Three-Month Term SOFR, reset quarterly, plus 315 basis points, or such other rate as determined pursuant to the
Indenture, payable quarterly in arrears on January 1, April 1, July 1 and October 1 of each year through the Stated Maturity Date or earlier Redemption Date (each, a “Floating Rate Interest Payment Date” and, together
with the Fixed Rate Interest Payment Dates, the “Interest Payment Dates,” with the period from, and including, April 1, 2027 to, but excluding, the first Floating Rate Interest Payment Date and each successive period from, and
including a Floating Rate Interest Payment Date to, but excluding, the next Floating Rate Interest Payment Date being a “Floating Rate Period”). The amount of interest payable on any Fixed Rate Interest Payment Date during the Fixed Rate
Period will be computed on the basis of a 360-day year consisting of twelve 30-day months up to, but excluding April 1, 2027, and, the amount of interest
payable on any Floating Rate Interest Payment Date during the Floating Rate Period will be computed on the basis of a 360-day year and the number of days actually elapsed. In the event that any scheduled
Interest Payment Date for this 

  
 A-2-3 












 
Subordinated Note falls on a day that is not a Business Day, then payment of interest payable on such Interest Payment Date will be paid on the next succeeding day which is a Business Day (any
payment made on such date will be treated as being made on the date that the payment was first due and no interest on such payment will accrue for the period from and after such scheduled Interest Payment Date); provided, that in the event that any
scheduled Floating Rate Interest Payment Date falls on a day that is not a Business Day and the next succeeding Business Day falls in the next succeeding calendar month, such Floating Rate Interest Payment Date will be accelerated to the immediately
preceding Business Day, and, in each such case, the amounts payable on such Business Day will include interest accrued to, but excluding, such Business Day. All percentages used in or resulting from any calculation of Three-Month Term SOFR shall be
rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with 0.000005% rounded up to 0.00001%. The Company will pay all Additional Interest (as defined in the Indenture), if any, on the dates and in the amounts set forth
in the Registration Rights Agreement (as defined in the Indenture). 
 The Company will pay interest on this Subordinated Note to the Person
who is the registered Holder at the close of business on the fifteenth day (whether or not a Business Day) prior to the applicable Interest Payment Date, except as provided in Section 2.10 of the Indenture with respect to Defaulted Interest.
This Subordinated Note will be payable as to principal and interest at the office or agency of the Paying Agent, or, at the option of the Company, payment of interest may be made by check delivered to the Holder at its address set forth in the
Subordinated Note Register or by wire transfer to an account appropriately designated by the Person entitled to payment; provided, that the Paying Agent will have received written notice of such account designation at least five Business Days
prior to the date of such payment (subject to surrender of this Subordinated Note in the case of a payment of interest at Stated Maturity). 

3. Paying Agent and Registrar. The Trustee, as Trustee under the Indenture, will act as the initial Paying Agent and Registrar through
its offices presently located at 5555 San Felipe Street, Suite 870, Houston, Texas 77056. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company or any of its Subsidiaries may act in any such capacity. 

4. Subordination. The indebtedness of the Company evidenced by this Subordinated Note, including the principal thereof and interest
thereon, is, to the extent and in the manner set forth in the Indenture, subordinate and junior in right of payment to obligations of the Company constituting the Senior Indebtedness (as defined in the Indenture) on the terms and subject to the
terms and conditions as provided and set forth in Article XI of the Indenture and will rank pari passu in right of payment with all other Subordinated Notes. Holder, by the acceptance of this Subordinated Note, agrees to and will be bound by such
provisions of the Indenture and authorizes and directs the Trustee on his behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided. 

  
 A-2-4 












 5. Redemption. 

a. The Company may, at its option, on any Interest Payment Date on or after April 1, 2027, redeem this Subordinated Note, in whole or in
part, without premium or penalty, but in all cases in a principal amount with integral multiples of $1,000. In addition, the Company may, at its option, redeem all, but not a portion of the Subordinated Notes, at any time upon the occurrence of a
Tier 2 Capital Event, a Tax Event or an Investment Company Event. Any redemption of this Subordinated Note shall be subject to the prior approval of the Federal Reserve (or its designee) or any successor agency, and any other bank regulatory agency,
to the extent such approval shall then be required by law, regulation or policy. This Subordinated Note is not subject to redemption at the option of the Holder. The Redemption Price with respect to any redemption permitted under the Indenture will
be equal to 100% of the principal amount of this Subordinated Note, or portion thereof, to be redeemed, plus accrued but unpaid interest and Additional Interest, if any, thereon to, but excluding, the Redemption Date. 

b. If less than the then outstanding principal amount of this Subordinated Note is redeemed, (i) a new note shall be issued representing
the unredeemed portion without charge to the Holder thereof and (ii) such redemption shall be effected on a pro rata basis as to the Holders. For purposes of clarity, upon a partial redemption, a like percentage of the principal amount of every
Subordinated Note held by every Holder shall be redeemed. 
 c. If notice of redemption has been duly given and notwithstanding that any
Subordinated Notes so called for redemption have not been surrendered for cancellation, on and after the Redemption Date interest shall cease to accrue on all Subordinated Notes so called for redemption, all Subordinated Notes so called for
redemption shall no longer be deemed outstanding and all rights with respect to such Subordinated Notes shall forthwith on such Redemption Date cease and terminate (unless the Company shall default in the payment of the redemption price), except
only the right of the Holder thereof to receive the amount payable on such redemption, without interest. 
 6. Events of Default;
Acceleration. An “Event of Default” means any one of the events described in Section 4.01 of the Indenture. If an Event of Default described in Section 4.01(1) or 4.01(2) of the Indenture occurs, then the principal amount of
all of the Outstanding Subordinated Notes, and accrued and unpaid interest, if any, on all Outstanding Subordinated Notes will become and be immediately due and payable without any declaration or other act on the part of the Trustee or the Holder,
and the Company waives demand, presentment for payment, notice of nonpayment, notice of protest, and all other notices. Notwithstanding the foregoing, upon the occurrence of an Event of Default other than an Event of Default described in
Section 4.01(1) or 4.01(2) of the Indenture, neither the Trustee nor the Holder may accelerate the Stated Maturity of the Subordinated Notes and make the principal of, and any accrued and unpaid interest on, the Subordinated Notes, immediately
due and payable. If any Event of Default occurs and is continuing, the Trustee may also pursue any other available remedy to collect the payment of principal of, and interest on, the Subordinated Notes then due and payable or to enforce the
performance of any provision of the Subordinated Notes or the Indenture. 
 7. Failure to Make Payments. If the Company fails to make
any payment of interest on this Subordinated Note when such interest becomes due and payable and such default continues for a period of 30 days, or if the Company fails to make any payment of the principal of this Subordinated Note when such
principal becomes due and payable, the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holder, the whole amount then due and payable with respect to this Subordinated Note, with interest upon the overdue
principal, any premium and, to the extent permitted by applicable law, upon any overdue installments of interest at the rate or respective rates, as the case may be, provided for or with respect to this Subordinated Note or, if no such rate or rates
are so provided, at the rate or respective rates, as the case may be, of interest borne by this Subordinated Note. 

  
 A-2-5 












 Upon an Event of Default, the Company may not declare or pay any dividends or distributions
on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Company’s capital stock, make any payment of principal or interest or premium, if any, on or repay, repurchase or redeem any debt securities of the
Company that rank equal with or junior to this Subordinated Note, or make any payments under any guarantee that ranks equal with or junior to this Subordinated Note, other than: (i) any dividends or distributions in shares of, or options,
warrants or rights to subscribe for or purchase shares of, any class of the Company’s common stock; (ii) any declaration of a dividend in connection with the implementation of a shareholders’ rights plan, or the issuance of stock
under any such plan in the future, or the redemption or repurchase of any such rights pursuant thereto; (iii) as a result of a reclassification of the Company’s capital stock or the exchange or conversion of one class or series of the
Company’s capital stock for another class or series of the Company’s capital stock; (iv) the purchase of fractional interests in shares of the Company’s capital stock in accordance with the conversion or exchange provisions of
such capital stock or the security being converted or exchanged; or (v) purchases of any class of the Company’s common stock related to the issuance of common stock or rights under any benefit plans for the Company’s directors,
officers or employees or any of the Company’s dividend reinvestment plans. 
 8. Denominations, Transfer, Exchange. The
Subordinated Notes are issuable only in registered form without interest coupons in minimum denominations of $100,000 and integral multiples of $1,000 in excess thereof. The transfer of this Subordinated Note may be registered and this Subordinated
Note may be exchanged as provided in the Indenture. The Registrar may require the Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require the Holder to pay any taxes and fees required by law
or permitted by the Indenture. 
 9. Charges and Transfer Taxes. No service charge will be made for any registration of transfer or
exchange of this Subordinated Note, or any redemption or repayment of this Subordinated Note, or any conversion or exchange of this Subordinated Note for other types of securities or property, but the Company may require payment of a sum sufficient
to pay all taxes, assessments or other governmental charges that may be imposed in connection with the transfer or exchange of this Subordinated Note from the Holder requesting such transfer or exchange. 

10. Persons Deemed Owners. The Company and the Trustee and any agent of the Company or the Trustee may treat the Person in whose name
this Subordinated Note is registered as the owner hereof for all purposes, whether or not this Subordinated Note is overdue, and neither the Company, the Trustee nor any such agent will be affected by notice to the contrary. 

11. Amendments; Waivers. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification
of the rights and obligations of the Company and the rights of the Holders of the Subordinated Notes at any time by the Company and the Trustee with the consent of the holders of a majority in principal amount of the then Outstanding Subordinated
Notes. The Indenture also contains provisions permitting the holders of 

  
 A-2-6 












 
specified percentages in principal amount of the then Outstanding Subordinated Notes, on behalf of the holders of all Subordinated Notes, to waive certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Subordinated Note will be conclusive and binding upon such Holder and upon all future holders of this Subordinated Note and of any Subordinated Note issued upon the registration of
transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Subordinated Note. 

12. No Impairment. No reference herein to the Indenture and no provision of this Subordinated Note or of the Indenture will alter or
impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest (if any) and Additional Interest on this Subordinated Note at the times, place and rate as herein prescribed, 

13. No Sinking Fund: No Convertibility. This Subordinated Note is not entitled to the benefit of any sinking fund. This Subordinated
Note is not convertible into or exchangeable for any of the equity securities, other securities or assets of the Company or any Subsidiary. 

14. No Recourse Against Others. No recourse under or upon any obligation, covenant or agreement contained in the Indenture or in this
Subordinated Note, or for any claim based thereon or otherwise in respect thereof, will be had against any past, present or future shareholder, employee, officer, or director, as such, of the Company or of any predecessor or successor, either
directly or through the Company or any predecessor or successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being
expressly waived and released by the acceptance of this Subordinated Note by the Holder and as part of the consideration for the issuance of this Subordinated Note.
