Section 103 Form of Documents Delivered to Trustee. In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based is erroneous. Any such certificate or opinion of counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous. Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture or any Subordinated Note, they may, but need not, be consolidated and form one instrument. Section 104 Acts of Holders. Any request, demand, authorization, direction, notice, consent, waiver or other action provided by or under this Indenture to be made, given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by an agent duly appointed in writing. Except as herein otherwise expressly provided, such action will become effective when such instrument or instruments or

Β 
10 record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the β€œAct” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Subordinated Note, will be sufficient for any purpose of this Indenture and (subject to Section 501) conclusive in favor of the Trustee and the Company and any agent of the Trustee or the Company, if made in the manner provided in this Section. The fact and date of the execution by any Person of any such instrument or writing may be proved in any reasonable manner that the Trustee deems sufficient and in accordance with such reasonable rules as the Trustee may determine, and the Trustee may in any instance require further proof with respect to any of the matters referred to in this Section. The ownership, principal amount and serial numbers of Subordinated Notes held by any Person, and the date of the commencement and the date of the termination of holding the same, will be proved by the Subordinated Note Register. The Company may, in the circumstances permitted by the Trust Indenture Act, set a record date for purposes of determining the identity of Holders entitled to give any request, demand, authorization, direction, notice, consent, waiver or take any other act authorized or permitted to be given or taken by Holders. Unless otherwise specified, if not set by the Company prior to the first solicitation of a Holder made by any Person in respect of any such action, any such record date will be the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation. If a record date is fixed, the Holders on such record date, and only such Persons, will be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such Holders remain Holders after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other action will be valid or effective if made, given or taken more than 90 days after such record date. Any effective request, demand, authorization, direction, notice, consent, waiver or other Act by the Holder of any Subordinated Note will bind every future Holder of the same Subordinated Note and the Holder of every Subordinated Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done or suffered to be done by the Trustee, any Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such Act is made upon such Subordinated Note. Without limiting the foregoing, a Holder entitled to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so in accordance with such appointment with regard to all or any part of such principal amount. Any notice given or action taken by a Holder or its agents with regard to different parts of such principal amount in accordance with this paragraph will have the same effect as if given or taken by separate Holders of each such different part.

Β 
11 Without limiting the generality of this Section 104, a Holder, including a Depositary that is a Holder of a Global Subordinated Note, may make, give or take, by a proxy or proxies, duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other Act provided in or under this Indenture or the Subordinated Notes to be made, given or taken by Holders, and a Depositary that is a Holder of a Global Subordinated Note may provide its proxy or proxies to the beneficial owners of interests in any such Global Subordinated Note through such Depositary’s Applicable Procedures. The Company may fix a record date for the purpose of determining the Persons who are beneficial owners of interests in any Global Subordinated Note entitled under the Applicable Procedures of such Depositary to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders. If such a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies, and only such Persons, will be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such Holders remain Holders after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other action will be valid or effective if made, given or taken more than 90 days after such record date. Promptly upon any record date being set in accordance with this Section 104, the Company, at its own expense, will cause notice of the record date, the proposed action by Holders and the expiration date to be given to the Trustee in writing and the Holders in the manner set forth in Section 105. Section 105 Required Notices or Demands. Any notice or communication by the Company or the Trustee to the others is duly given if in writing and delivered in Person or mailed by registered or certified mail (return receipt requested), facsimile or overnight air courier guaranteeing next day delivery, to the other’s address: If to the Company: First NBC Bank Holding Company 000 Xxxxxxx Xxxxxx Xxx Xxxxxxx, XX 00000 Attention: Xxxxxxx X. Xxxxx Facsimile: (000) 000-0000 If to the Trustee: U.S. Bank National Association, as Trustee 0000 Xxx Xxxxxx, Xxxxx 0000 Xxxxxxx, Xxxxx 00000 Attention: Corporate Trust Services Facsimile: (000) 000-0000 The Company or the Trustee by notice to the other may designate additional or different addresses for subsequent notices or communications.

Β 
12 All notices and communications will be deemed to have been duly given: at the time delivered by hand, if personally delivered; five Business Days after being deposited in the mail, postage prepaid, if mailed; on the first Business Day after being sent, if sent by facsimile and the sender receives confirmation of successful transmission; and the next Business Day after timely delivery to the courier, if sent by overnight air courier guaranteeing next day delivery. Any notice required or permitted to be given to a Holder under the provisions of this Indenture will be deemed to be properly mailed by being deposited postage prepaid in a post office letter box in the United States addressed to such Holder at the address of such Holder as shown on the Subordinated Note Register. Any report in accordance with Section 313 of the Trust Indenture Act will be transmitted in compliance with subsection (c) therein. If the Company mails a notice or communication to Holders, the Company will mail a copy to the Trustee at the same time. In any case where notice to Holders of Subordinated Notes is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Subordinated Note will affect the sufficiency of such notice with respect to other Holders of Subordinated Notes. Any notice that is mailed in the manner herein provided will be conclusively presumed to have been duly given or provided. In the case by reason of the suspension of regular mail service or by reason of any other cause it will be impracticable to give such notice by mail, then such notification as will be made with the approval of the Trustee will constitute a sufficient notification for every purpose hereunder. Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver will be the equivalent of such notice. Waivers of notice by Holders of Subordinated Notes will be filed with the Trustee, but such filing will not be a condition precedent to the validity of any 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 prescribed for giving such notice. Section 106 Language of Notices. Any request, demand, authorization, direction, notice, consent or waiver or other Act required or permitted under this Indenture will be in the English language, except that, if the Company so elects, any published notice may be in an official language of the country of publication.

ARTICLE II. THE SUBORDINATED NOTES Section 201 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. Section 202 Definitive Subordinated Notes. The Initial Notes will be issued initially in the form of one or more Definitive 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 207, 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. Section 203 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 207 hereof and will be made on the records of the Trustee and the Depositary.

Β 
17 Section 204 Restricted Subordinated Notes. Each Definitive Restricted Note and Global Restricted Note will bear a legend in substantially the following form: β€œTHE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE β€œSECURITIES ACT”) OR UNDER ANY APPLICABLE STATE SECURITIES LAW. THESE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OR (B) AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY, IF REQUESTED, OR (II) UNLESS SOLD IN ACCORDANCE WITH RULE 144 UNDER SAID ACT.” The restrictive legend set forth above will be removed and a new Subordinated Note of like tenor and principal amount without such restrictive 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, if legal counsel to the Holder or owner of beneficial interests requesting the removal of such legend 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 Subordinated Note is eligible for immediate resale, without any remaining holding period, under Rule 144 without the requirement for the Company to be in compliance with the current public information required under Rule 144 as to such securities. Section 205 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 $60,000,000 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 authenticate and deliver any Exchange Notes for an aggregate principal amount not to exceed $60,000,000 specified in such Company Order for Exchange Notes issued hereunder. The aggregate principal amount of Outstanding Subordinated Notes at any time

Β 
18 may not exceed the amount set forth in the foregoing sentence, except as provided in Section 209. The Subordinated Notes will be issued only in registered form without coupons and in minimum denominations of $1,000 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. 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. Section 206 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 (β€œRegistrar”) and an office or agency where Subordinated Notes may be presented for payment (β€œPaying Agent”). The Registrar will keep a register of the Subordinated Notes (β€œSubordinated 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 β€œRegistrar” includes any co-registrar and the term β€œPaying 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. Section 207 Registration of Transfer and Exchange. 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 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

Β 
19 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 $1,000 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, the Subordinated Notes that the Holder making the exchange is entitled to receive. 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 1003 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 appointed in accordance with Section 206 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 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

Β 
20 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, and to examine the same to determine substantial compliance as to form with the express requirements hereof. Neither the Trustee nor any Paying Agent will have any responsibility for any actions taken or not taken by the Depositary. 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 Xxxxxx’s attorney duly authorized in writing. 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 β€œclearing 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, 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 209 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 207 or Section 209 hereof, will be authenticated and delivered in the form of, and will be, a Global

Β 
21 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 207(3); however, beneficial interests in a Global Subordinated Note may be transferred and exchanged as provided in Section 207(4) hereof. Any Global Subordinated Note to be exchanged in whole will be surrendered by the Depositary to the Trustee, as Registrar. 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. 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 207. 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, 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. 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 212 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

Β 
22 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. No Restricted Subordinated Note will be transferred or exchanged except in compliance with the legend set forth in Section 204 or as provided in accordance with Section 208. In addition to the provisions for transfer and exchange set forth in this Section 207, 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 208, 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 legend set forth in Section 204 and that the Subordinated Note issued to the transferee or in exchange for the Restricted Subordinated Note may be issued free of the legend set forth in Section 204. Any untransferred or unexchanged balance of a Restricted Subordinated Note will be reissued to the Holder with the legend set forth in Section 204, unless the legend may be omitted in accordance with Section 204, as evidenced by the Opinion of Counsel. Section 208 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 205 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 or, if permitted by the Company, (ii) one or more Unrestricted Global Subordinated Notes in an aggregate principal amount equal to the 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 Definitive 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 mail to the Persons designated by the Holders of Definitive Subordinated Notes so accepted Unrestricted Definitive Subordinated Notes in the applicable principal amount. Any Subordinated 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.

Β 
23 Section 209 Mutilated, Destroyed, Lost and Stolen Subordinated Notes. If any mutilated Subordinated Note is surrendered to the Trustee, subject to the provisions of this Section 209, 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. 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 209, 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, the Company in its discretion may, instead of issuing a new Subordinated Note, pay 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. Section 210 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. 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 β€œDefaulted Interest”) will cease to be payable to the Holder thereof on the relevant Regular Record

Β 
24 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: 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 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 the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the 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 mailed, first-class postage prepaid, 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. The Company may, in its discretion, in the name and at the expense of the Company cause a similar notice to be published at least once in an Authorized Newspaper of general circulation in the City of Houston, Texas, but such publication will not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest 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). 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 of America. Subject to the foregoing provisions of this Section and Section 206, 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.

Β 
25 Section 211 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 206 and Section 210) 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. 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. Section 212 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 Notes, 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 the Trustee upon the written request of the Company will deliver to the Company a certificate of such disposition, or if directed by a Company Order returned to the Company.

Β 
26 Section 213 Computation of Interest. Interest on the Subordinated Notes will be computed on the basis of a 360-day year of twelve 30-day months and, for any period less than a full month, on the number of days actually elapsed. Section 214 CUSIP Numbers. The Company may issue the Subordinated Notes with one or more β€œCUSIP” numbers (if then generally in use). The Company will promptly notify the Trustee of any change in the CUSIP numbers. The Trustee may use β€œCUSIP” 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 Section 301 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 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 209 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 903) 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 Maturity thereof, as the case may be;

Β 
27 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 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. Notwithstanding the satisfaction and discharge of this Indenture with respect to the Subordinated Notes, the obligations of the Company to the Trustee under Section 507 and, if money will have been deposited with the Trustee in accordance with Section 301(1)(b), the obligations of the Company and the Trustee with respect to the Subordinated Notes under Section 303 and Section 903, any rights of Holders to require the Company to repurchase or repay, and any rights of Holders to convert or exchange, and the obligations of the Company to convert or exchange, such Subordinated Notes into Common Stock or other securities or property, will survive. Section 302 Defeasance and Covenant Defeasance. The Company may at its option and at any time, elect to have Section 302(2) or Section 302(3) be applied to such Outstanding Subordinated Notes upon compliance with the conditions set forth below in this Section 302. Legal Defeasance and Covenant Defeasance may be effected only with respect to all, and not less than all, of the Outstanding Subordinated Notes. Upon the Company’s exercise of the above option applicable to this Section 302(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 302 are satisfied (β€œLegal 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 β€œOutstanding” only for the purposes of Section 302(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 302(4)(a) and as more fully set forth in this Section 302 and Section 303, 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 206, Section 209, Section 902 and Section 903, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 302 and Section 303. The Company may exercise its option under this Section 302(2) notwithstanding the prior exercise of its option under Section 302(3) with respect to such Subordinated Notes. Upon the Company’s exercise of the above option applicable to this Section 302(3), the Company will be released from its obligations under clauses (ii) and (iii) of Section 904 and under Section 905, Section 906 and Section 907 on and after the date the

Β 
28 conditions set forth in Section 302(4) are satisfied (β€œCovenant Defeasance”), and such Subordinated Notes will thereafter be deemed to be not β€œOutstanding” 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 β€œOutstanding” 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. The following will be the conditions to application of Section 302(2) or Section 302(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 508 who will agree to comply with the provisions of this Section 302 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 302(2), no Event of Default, or event which with notice or lapse of time or both would become an Event of Default, under Section 401 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 302(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 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,

Β 
29 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 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. (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 302(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. Subject to the provisions of the last paragraph of Section 903, all money and Government Obligations deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 302(5), the β€œTrustee”) in accordance with Section 302(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 302 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. Section 303 Application of Trust Money. Subject to the provisions of the last paragraph of Section 903, all money and Government Obligations deposited with the Trustee in accordance with Section 301 or Section 302 will be held in trust and applied by the Trustee, in accordance with the provisions of such Subordinated Notes

Β 
30 subject to discharge under Section 301 or Legal Defeasance or Covenant Defeasance under Section 302, 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. Section 304 Reinstatement. If the Trustee (or other qualifying trustee appointed in accordance with Section 302(4)(a)) or any Paying Agent is unable to apply any moneys or Government Obligations deposited in accordance with Section 301(1) or Section 302(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 301 or Section 302 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. Section 305 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 301 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 302. As a result, and anything herein to the contrary notwithstanding, if the Company complies with the provisions of Section 301 to effect the satisfaction and discharge of the Subordinated Notes or complies with the provisions of Section 302 to effect the Legal Defeasance or Covenant Defeasance, upon the effectiveness of such satisfaction and discharge in accordance with Section 301 or of Legal Defeasance or Covenant Defeasance in accordance with Section 302, in the case of satisfaction and discharge in accordance with Section 301, or, in the case of Legal Defeasance or Covenant Defeasance in accordance with Section 302, 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

Β 
31 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. ARTICLE IV. REMEDIES Section 401 Events of Default; Acceleration. An β€œEvent 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): 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 of America or any political subdivision thereof, and such decree or order will have continued unstayed and in effect for a period of 60 consecutive days; 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 of America 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; 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; 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; 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 β€œNotice of Default” hereunder and demanding that the Company remedy the same, will have been given, in the manner set forth in Section 105, 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 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 $25,000,000, 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.

Β 
32 Upon becoming aware of any Event of Default, the Company will promptly deliver to the Trustee a written statement specifying the Event of Default. If an Event of Default described in Section 401(1) or Section 401(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, because the Company will treat the Subordinated Notes as tier 2 capital (or its then equivalent if the Company were subject to such capital requirement) for purposes of capital adequacy guidelines of the Federal Reserve Board as then in effect and applicable to the Company, upon the occurrence of an Event of Default other than an Event of Default described in Section 401(1) or Section 401(2), neither the Trustee nor the Holder may accelerate the 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 or to enforce the performance of any provision of the Subordinated Notes or this Indenture. Section 402 Failure to Make Payments. If the Company fails to make any payment of interest on any 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 any 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 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 507. If the Company fails to pay the money it is required to pay the Trustee upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, 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 in its discretion 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

Β 
33 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 the occurrence of a failure by the Company to make any required payment of principal or interest on the Subordinated Notes, 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 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 of benefit plans for Company’s directors, officers or employees or any of Company’s dividend reinvestment plans. Section 403 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 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 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 the Trustee under Section 507.

Β 
34 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. Section 404 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. Section 405 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: FIRST: To the payment of all amounts due the Trustee (including any predecessor trustee) under Section 507; SECOND: To the payment of amounts then due and unpaid to the holders of Senior Indebtedness, to the extent required under the Subordination Provisions established with respect to the Subordinated Notes; THIRD: To the payment of the amounts then due and unpaid for principal of and any interest on the Subordinated Notes in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the aggregate amounts due and payable on such Subordinated Notes for principal and interest, respectively; and FOURTH: The balance, if any, to the Person or Persons entitled thereto. Section 406 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 for the appointment of a receiver or trustee, or for any other remedy under this Indenture, unless: such Xxxxxx has previously given written notice to the Trustee of a continuing Event of Default with respect to the Subordinated Notes;

Β 
35 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; such Holder or Holders have offered to the Trustee indemnity reasonably satisfactory to the Trustee against the costs, expenses, and liabilities to be incurred in compliance with such request; the Trustee for 60 days after its receipt of such notice, request, and offer of indemnity has failed to institute any such proceeding; and 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 principal amount of the Outstanding Subordinated Notes; 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. Section 407 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 206 and Section 210) 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. Section 408 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. Section 409 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 209, 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

Β 
36 any right or remedy under this Indenture, or otherwise, will not prevent the concurrent assertion or employment of any other appropriate right or remedy. Section 410 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. Section 411 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 such direction will not violate any rule of law or this Indenture or the Subordinated Notes, the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and the Trustee will have the right to decline to follow any such direction if the Trustee in good faith will, by a Responsible Officer or Officers of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability. Section 412 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. Section 413 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

Β 
37 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 413 will not apply to 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). ARTICLE V. THE TRUSTEE Section 501 Duties of Trustee. If an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it hereby, and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

Whether or not therein expressly so provided, every provision hereof that in any way relates to the Trustee is subject to paragraphs (1) and (2) of this Section 501 and to Section 502. No provision hereof will require the Trustee to expend or risk its own funds or incur any liability.

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 510. 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 will be 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 510, become the successor Trustee with respect to the

Β 
43 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 510, 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.

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

Β 
44 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 its charges with respect to the Subordinated Notes and subject to Section 903 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 507. 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. 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.

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. Section 512 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 209, 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.

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 mail 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 512. 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 507. The provisions of Section 211, Section 504 and Section 505 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: This is one of the Subordinated Notes designated herein referred to in the within-mentioned Indenture.

Β 
53 The Company hereby designates the Corporate Trust Office of the Trustee as one such office or agency of the Company in accordance with Section 902. Section 903 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 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; provided, however, that the Trustee or such Paying Agent,

Β 
54 before being required to make any such repayment, may, not later than 30 days after the Company’s request for such repayment, at the expense of the Company cause to be published once, in an Authorized Newspaper in each Place of Payment or to be mailed to such Holders of Subordinated Notes, or both, notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such publication or mailing nor will it be earlier than two years after such principal and or interest will have become due and payable, any unclaimed balance of such money then remaining will be repaid to the Company.

Section 905 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. Section 906 Waiver of Certain Covenants. The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 902 to Section 905, 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.

56 Section 1003 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, by lot or such method as the Trustee will deem fair and appropriate and which may provide for the selection for redemption of portions of the principal amount of Subordinated Notes; 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. 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. 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. Section 1004 Notice of Redemption. Notice of redemption will be given in the manner provided in Section 105, 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 mailing 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 mailed 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: the Redemption Date, the Redemption Price, 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, 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,

Β 
57 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 1006), and, if applicable, that interest thereon will cease to accrue on and after said date, 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 the authority for such redemption. The notice of redemption may 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). 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), by the Trustee in the name and at the expense of the Company. Section 1005 Deposit of Redemption Price. On or prior to 11:00 a.m., Houston, Texas time, on any Redemption Date, the Company will deposit, with respect to the Subordinated Notes called for redemption in accordance with Section 1004, 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 903) 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. Section 1006 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, 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 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 210. 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.

Β 
58 Section 1007 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 Subordinated Note in global form is so surrendered, the Company will execute, and the Trustee will authenticate and deliver to the Depositary for such Subordinated Note in global form as will be specified in the Company Order with respect thereto to the Trustee, without service charge, a new Subordinated Note in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Subordinated Note in global form 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 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 Section 1101 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. Section 1102 Distribution of Assets. 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) the 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

Β 
59 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 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 1102(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. 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

Β 
60 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 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 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 hereof 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 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.

Β 
61 Section 1103 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. Section 1104 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 1102 and Section 1103, 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. Section 1105 Effectuation of Subordination Provisions. Each Holder by his acceptance of any Notes authorizes and expressly directs the Trustee on such Xxxxxx’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.

Β 
62 Section 1106 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 unless and until the Trustee will have received notice in writing at its Corporate Trust Office to that effect 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 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 1106 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 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. Section 1107 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 or 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.

Β 
63 Section 1108 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. Section 1109 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 507 of this Indenture.

No. CUSIP 32115D AA4 FIRST NBC BANK HOLDING COMPANY 5.75% SUBORDINATED NOTE DUE 2025 1. Indenture; Holders. This note is one of a duly authorized issue of notes of First NBC Bank Holding Company, a Louisiana corporation (the β€œCompany”), designated as the β€œ5.75% Subordinated Notes due 2025” (the β€œSubordinated Notes”) in an aggregate principal amount of $60,000,000 and initially issued on February 18, 2015. The Company has issued this Subordinated Note under that certain Indenture dated as of February 18, 2015, as the same may be amended or supplemented from time to time (β€œIndenture”), between the Company and U.S. Bank National Association, as Trustee. All capitalized terms not otherwise defined herein this Subordinated Note will have the meanings assigned to them in the Indenture. The terms of this Subordinated Note includes those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act. This Subordinated Note is subject to all such terms, and the Holder (as defined below) is referred to the Indenture and the Trust Indenture Act for a statement of such terms. To the extent any provision of this Subordinated Note irreconcilably conflicts with the express provisions of the Indenture, the provisions of the Indenture will govern and be controlling. 2. Payment. The Company, for value received, promises to pay to , or registered assigns (the β€œHolder”), the principal sum of Dollars (U.S.) ($ ), plus accrued but unpaid interest on February 18, 2025 (β€œStated Maturity”) and to pay interest thereon at the rate of 5.75% per annum from February 18, 2015, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on February 18 and August 18 of each year (each, an β€œInterest Payment Date”), commencing August 18, 2015, until the principal hereof is paid or made available for payment, with such interest calculated on the basis of a 360-day year consisting of twelve 30-day months and the number of days elapsed in any partial month. Any payment of principal of or interest on this Subordinated Note that would otherwise become due and payable on a day which is not a Business Day will become due and payable on the next succeeding Business Day, with the same force and effect as if made on the date for payment of such principal or interest, and no interest will accrue in respect of such payment for the period after such day.

Β 
A-1-3 The Company will pay interest on this Subordinated Note to the Person who is the registered Holder at the close of business on the first calendar day of the month in which the Interest Payment Date occurs, except as provided in Section 210 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 mailed 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 Maturity). 3. Paying Agent and Registrar. U.S. Bank National Association, the Trustee (β€œTrustee”) under the Indenture, will act as the initial Paying Agent and Registrar through its offices presently located at 0000 Xxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000. 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 XII 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. 5. Redemption. The Company may, at any time or from time to time on or after November 18, 2024, 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 redeem all, but not a portion of the Subordinated Notes, at any time upon the occurrence of a Tier 2 Capital Event, Tax Event or an Investment Company Event. Any redemption with respect to this Subordinated Note will be subject to any required regulatory approvals. This Subordinated Note is not subject to redemption at the option of the Holder. The Redemption Price with respect to any redemption permitted under this 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. 6. Events of Default; Acceleration. An β€œEvent of Default” means any one of the events described in Section 401 of the Indenture. If an Event of Default described in Section 401(1) or Section 401(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, because the Company will treat the Subordinated Notes as tier 2 capital (or its then

Β 
A-1-4 equivalent if the Company were subject to such capital requirement) for purposes of capital adequacy guidelines of the Federal Reserve Board as then in effect and applicable to the Company, upon the occurrence of an Event of Default other than an Event of Default described in Section 401(1) or Section 401(2) of the Indenture, neither the Trustee nor the Holder may accelerate the 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 or to enforce the performance of any provision of the Subordinated Notes or the Indenture. 7.

This note is one of a duly authorized issue of notes of First NBC Bank Holding Company, a Louisiana corporation (the β€œCompany”) designated as the β€œ5.75% Subordinated Notes due 2025” (the β€œSubordinated Notes”) in an aggregate principal amount of $60,000,000 and initially issued on February 18, 2015. The Company has issued this Subordinated Note under that certain Indenture dated as of February 18, 2015, as the same may be amended or supplemented from time to time (β€œIndenture”), between the Company and U.S. Bank National Association, as Trustee.

The terms of this Subordinated Note includes those stated in the Indenture and those made part of the Indenture by reference to 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 Cede & Co. or registered assigns (β€œHolder”), the principal sum of Dollars (U.S.) ($ ), plus accrued but unpaid interest on February 18, 2025 (β€œStated Maturity”) and to pay interest thereon at the rate of 5.75% per annum from February 18, 2015, or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semiannually in arrears on February 18 and August 18 of each year (each, an β€œInterest Payment Date”), commencing August 18, 2015, until the principal hereof is paid or made available for payment, with such interest calculated on the basis of a 360-day year consisting of twelve 30-day months and the number of days elapsed in any partial month. Any payment of principal of or interest on this Subordinated Note that would otherwise become due and payable on a day which is not a Business Day will become due and payable on the next succeeding Business Day, with the same force and effect as if made on the date for payment of such principal or interest, and no interest will accrue in respect of such payment for the period after such day. The Company will pay interest on this Subordinated Note to the Person who is the registered Holder at the close of business on the first calendar day of the month in which the Interest Payment Date occurs, except as provided in Section 210 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 mailed 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 Maturity).

Β 
A-2-4 3. Paying Agent and Registrar. U.S. Bank National Association, the Trustee (β€œTrustee”) under the Indenture, will act as the initial Paying Agent and Registrar through its offices presently located at 0000 Xxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000. 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 XII 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. 5. Redemption. The Company may, at any time or from time to time on or after November 18, 2024, 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 redeem all, but not a portion of the Subordinated Notes, at any time upon the occurrence of a Tier 2 Capital Event, Tax Event or an Investment Company Event. Any redemption with respect to this Subordinated Note will be subject to any required regulatory approvals. This Subordinated Note is not subject to redemption at the option of the Holder. The Redemption Price with respect to any redemption permitted under this 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. 6. Events of Default; Acceleration. An β€œEvent of Default” means any one of the events described in Section 401 of the Indenture. If an Event of Default described in Section 401(1) or Section 401(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, because the Company will treat the Subordinated Notes as tier 2 capital (or its then equivalent if the Company were subject to such capital requirement) for purposes of capital adequacy guidelines of the Federal Reserve Board as then in effect and applicable to the Company, upon the occurrence of an Event of Default other than an Event of Default described in Section 401(1) or Section 401(2) of the Indenture, neither the Trustee nor the Holder may accelerate the 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 or to enforce the performance of any provision of the Subordinated Notes or the Indenture.
