provided in this Section. The record of any meeting of Holders of Securities shall be proved in the manner provided in Section 1406.

Holders, and a Depositary that is a Holder of a global Security may provide its proxy or proxies to the beneficial owners of interests in any such global Security through such Depositary’s standing instructions and customary practices.

 (2) The fact and date of the execution by any Person of any such instrument or writing may be proved in any reasonable manner

(3) The ownership, principal amount and serial numbers of Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, shall be proved by the Security Register. 
 (4) If the Company shall solicit from the

Holders of Securities entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be
given before or after such record date, but only the Holders of Securities of record at the close of business on such record date shall be deemed to be Holders for the purpose of determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of such record date; provided that no
such authorization, agreement or consent by the Holders of Securities shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date. 

(5) Any request, demand, authorization, direction, notice, consent, waiver or other Act by the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security 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 Security
Registrar, any Paying Agent or the Company in reliance thereon, whether or not notation of such Act is made upon such Security.

 Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed
with, 
 (1) the Trustee by any Holder or the Company shall be sufficient for every purpose hereunder if made, given, furnished
or filed in writing to or with the Trustee at its Corporate Trust Office, or 
 (2) the Company by the Trustee or any Holder
shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid, to the Company addressed to the attention of its Treasurer at the address of its principal office
specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company.

of Securities if in writing and mailed, first-class postage prepaid, to each Holder of a Security affected by such event, at his address as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice. 
 In any case where notice to Holders of Securities 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 Security shall affect the sufficiency of such notice with respect to other Holders of Securities. Any notice that is mailed in the manner herein
provided shall 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 shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall 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 shall be the
equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

shall control.

impaired thereby.

a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or any Security other than a provision in any Security or in the Board Resolution, Officers’ Certificate or supplemental indenture establishing
the terms of any Security that specifically states that such provision shall apply in lieu hereof) payment need not be made at such Place of Payment on such date, but such payment may be made on the next succeeding day that is a Business Day at such
Place of Payment with the same force and effect as if made on the Interest Payment Date, at the Stated Maturity or Maturity or on any such other payment date, as the case may be, and no interest shall accrue on the amount payable on such date or at
such time for the period from and after such Interest Payment Date, Stated Maturity, Maturity or other payment date, as the case may be, to the next succeeding Business Day. 

 

	 	Section 115.	Counterparts; Electronic Transmission.

copies hereof or signature hereon shall, for all purposes, be deemed originals. 
  

	 	Section 116.	Immunity of Shareholders, Directors, Officers and Agents of the Company.

amount as is permitted by the terms thereof) from time to time set forth in such Securities in global form endorsed thereon or reflected on the books and records of the Trustee and may also provide that the aggregate amount of Outstanding Securities

	 	Section 301.	Amount Unlimited; Issuable in Series. 

 The aggregate principal amount of Securities that may be authenticated and delivered under this Indenture is unlimited. The Company may issue up to the aggregate principal amount of Securities of a Series
from time to time authorized by or pursuant to one or more Board Resolutions. The Securities shall be subordinated in right of payment to Senior Indebtedness as provided in Article Fifteen. 

The Securities may be issued in one or more Series. All Securities of each Series issued under this Indenture shall in all respects be
equally and ratably entitled to the benefits hereof with respect to that Series without preference, priority or distinction on account of the actual time or times of the authentication and delivery or Maturity of the Securities of such Series.
Unless expressly provided otherwise with respect to a Series, not all Securities of a Series need be issued at the same time, and, unless otherwise provided in the Securities of that Series or in this Indenture, a Series may be reopened and the
aggregate principal amount of the Securities of a Series may be increased and additional Securities of that Series may be issued up to a maximum aggregate principal amount authorized for that Series, as that maximum aggregate principal amount may be
increased from time to time. All Securities of a Series shall rank equally among themselves and with the other existing and future indebtedness of the Company that is subordinated in right of payment to the Senior Indebtedness to the same extent as
the Securities of that Series. 

  
 13 

 The Company may from time to time establish one or more Series pursuant to this Indenture. A
Series shall be established by (1) the execution and delivery of a Supplemental Indenture or (2) the adoption of a Board Resolution by the Board of Directors establishing that Series. The specific terms and conditions of the Securities of
any Series established shall be determined and set either (1) by the Supplemental Indenture that establishes the Series, (2) if the Series is established by a Supplemental Indenture, to the extent that those specific terms and conditions
are not determined and set by that Supplemental Indenture, by the adoption of a Board Resolution or Board Resolutions by the Board of Directors and, to the extent that those specific terms and conditions are not determined and set by the
Supplemental Indenture or by the adoption of a Board Resolution or Board Resolutions by the Board of Directors or by a combination of those means of determining and setting the specific terms and conditions of the Securities of that Series, by the
action of one or more Authorized Officers pursuant to authority to determine and set the specific terms and conditions of the Securities of that Series specifically delegated by the Board of Directors to that Authorized Officer or those Authorized
Officers or (3) if the Series is established by action of the Board of Directors, to the extent that those specific terms and conditions are not set by the adoption of a Board Resolution or Board Resolutions by the Board of Directors, by the
action of one or more Authorized Officers pursuant to authority to determine and set the specific terms and conditions of the Securities of that Series specifically delegated by the Board of Directors to that Authorized Officer or those Authorized
Officers. If the specific terms and specific conditions of the Securities of a Series are determined and set by action of the Board of Directors, that action shall be evidenced by a Board Resolution. If the specific terms and conditions of the
Securities of a Series established by action of the Board of Directors are determined and set by an Authorized Officer or Authorized Officers pursuant to authority delegated to them by the Board of Directors, that action shall be evidenced by an
Officers’ Certificate executed by the Authorized Officer or Authorized Officers determining and setting those terms and conditions, which certificate shall also be attested to by the Secretary or an Assistant Secretary of the Company. If the
specific terms and conditions of the Securities of a Series established by action of the Board of Directors are determined and set by an Authorized Officer or Authorized Officers pursuant to authority delegated to them by the Board of Directors and
an Officers’ Certificate has been delivered in connection with the establishment of the terms and conditions of the Securities of a Series and the issuance of the Securities of that Series, an additional Officers’ Certificate shall not be
required to be delivered in connection with any subsequent issuance of additional Securities of that Series. 
 Upon a Series
being established and the specific terms and conditions of the Securities of that Series being determined and set otherwise than through a Supplemental Indenture, the Company shall cause to be delivered to the Trustee an Officers’ Certificate
certifying that the Series has been established and the specific terms and conditions of the Securities of the Series have been determined and set and attaching to that Officers’ Certificate (1) the Board Resolution establishing the
Series, (2) the Board Resolution or Board Resolutions determining and setting the specific terms and conditions of the Securities of that Series or providing for the delegation of authority to one or more Authorized Officers to determine and
set the specific terms and conditions of the Securities of that Series and (3) if an Authorized Officer or Authorized Officers has determined and set the specific terms and conditions of the Securities of that Series, attaching the Certificate
evidencing the action of that Authorized Officer or those Authorized Officers. The Officers’ Certificate that is required to be delivered to the Trustee in accordance with the immediately preceding sentence, may be provided before or at the
time of the consummation of the first issuance of Securities of the Series to which the Officers’ Certificate relates. 

Each Board Resolution of the Company determining and setting the specific terms and conditions of the Securities of a Series, each
Officers’ Certificate evidencing the specific terms and conditions of the Securities of a Series, and each Supplemental Indenture setting forth the terms and conditions of the Securities of a Series, shall set forth the following information as
to the terms and conditions of that Series: 
 (1) the title of the Securities of such Series; 

(2) the aggregate principal amount of the Securities of such Series to be initially issued and sold by the Company and any limit upon the
aggregate principal amount of Securities of such Series that may be authenticated and delivered under this Indenture (except for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other
Securities of such Series pursuant to Section 304, Section 305, Section 306, Section 905 or Section 1107 or upon surrender in part of any Security for conversion or exchange into Common
Stock or other securities or property pursuant to its terms), and if from time to time the Company may issue additional Securities of such Series or establish additional terms of the Securities of such Series;

 (3) if any of such Securities of such Series are to be issuable in global form, when any of
such Securities are to be issuable in global form and (i) whether such Securities are to be issued in temporary or permanent global form or both, (ii) the conditions upon which Securities in definitive form will be issued to beneficial
owners of Securities of Series; (iii) whether beneficial owners of interests in any such global Security may exchange such interests for Securities of the same Series and of like tenor and of any authorized form and denomination, and the
circumstances under which any such exchanges may occur, if other than in the manner specified in Section 305, (iv) the name of the Depositary with respect to any such global Security and (v) if applicable and in addition to the
Persons specified in Section 305, the Person or Persons who shall be entitled to make any endorsements on any such global Security and to give the instructions and take the other actions with respect to such global Security contemplated
by the first paragraph of Section 203; 
 (4) the date or dates, or the method or methods, if any, by which such
date or dates shall be determined, on which the principal and premium, if any, of such Securities is payable; 
 (5) the rate or
rates at which such Securities shall bear interest, if any, or the method or methods, if any, by which such rate or rates are to be determined, the date or dates, if any, from which such interest shall accrue or the method or methods, if any, by
which such date or dates are to be determined, the Interest Payment Dates, if any, on which such interest shall be payable and the Regular Record Date, if any, for the interest payable on such Securities on any Interest Payment Date, the notice, if
any, to Holders regarding the determination of interest on a floating rate Security and the manner of giving such notice, and the basis upon which interest shall be calculated if other than that of a 360-day year of twelve 30-day months; 

(6) if in addition to or other than Dallas, Texas, the place or places where the principal of, any premium and interest on, such
Securities shall be payable, any of such Securities may be surrendered for registration of transfer or exchange, any of such Securities may be surrendered for conversion or exchange, and notices or demands to or upon the Company in respect of such
Securities and this Indenture may be served; 
 (7) whether any of the Securities are subject to prepayment and, if so, any
premium payable in connection with any such prepayment; 
 (8) whether any of such Securities are to be redeemable at the option
of the Company and, if so, the date or dates on which, the period or periods within which, the price or prices at which and the other terms and conditions upon which such Securities may be redeemed, in whole or in part, at the option of the Company;

 (9) if the Company is obligated to redeem or purchase any of such Securities pursuant to any sinking fund or analogous
provision or at the option of any Holder thereof and, if so, the date or dates on which, the period or periods within which, the price or prices at which and the other terms and conditions upon which such Securities shall be redeemed or purchased,

Securities or the administration thereof; 
 (12) if other than the principal amount thereof, the portion of the principal
amount of any of such Securities that shall be payable upon declaration of acceleration of the Maturity thereof pursuant to Section 502 or the method by which such portion is to be determined; 

(13) if the amount of payments of principal of, or any premium or interest on, such Securities may be determined with reference to an
index, formula or other method or methods (which index, formula or method or methods may be based, without limitation, on one or more commodities, equity indices or other indices), and, if so, the terms and conditions upon which and the manner in
which such amounts shall be determined and paid or payable; 

  
 15 

 (14) any affirmative or negative covenants to which the Company shall be subject or
obligated to perform so long as any Security of such Series is Outstanding; 
 (15) any deletions from, modifications of, or
additions to, the Events of Default or covenants of the Company with respect to any of such Securities (whether or not such Events of Default or covenants are consistent with the Events of Default or covenants set forth herein), and if

 (16) if any one or more of
Section 401 relating to satisfaction and discharge, Section 402(2) relating to defeasance or Section 402(3) relating to covenant defeasance shall not be applicable to the Securities of such Series, and any
covenants in addition to or other than those specified in Section 402(3) relating to the Securities of such Series that shall be subject to covenant defeasance, and, if the Holders of such Securities have the right to convert or exchange
such Securities into Common Stock or other securities or property, if the right to effect such conversion or exchange will be subject to satisfaction and discharge pursuant to Section 401 or to defeasance or covenant defeasance pursuant
to Section 402, and any deletions from, or modifications or additions to, the provisions of Article Four (including any modification which would permit satisfaction and discharge, defeasance or covenant defeasance to be
effected with respect to less than all of the outstanding Securities of such Series) in respect of the Securities of such Series; 
 (17) if any of such Securities are issuable in global form and are to be issuable in definitive form (whether upon original issue or upon exchange of a temporary Security) only upon receipt of certain
certificates or other documents or satisfaction of other conditions, then the form and terms of such certificates, documents or conditions; 
 (18) if not the Trustee, the identity of each Security Registrar, Paying Agent or Authenticating Agent with respect to such Securities; 

(19) the Person to whom any interest on any Security of such Series shall be payable, if other than the Person in whose name the Security
(or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, and the extent to which, or the manner in which, any interest payable on a temporary global Security will be paid if other
than in the manner provided in this Indenture; 
 (20) the terms pursuant to which the Securities of such Series will be made
subordinate in right of payment to Senior Indebtedness, the definition of such Senior Indebtedness with respect to such Series and any changes in Article Fifteen with respect to such Series; and a Board Resolution, Officers’
Certificate or supplemental indenture, as the case may be, establishing the terms of such Series shall expressly state which articles, sections or other provisions thereof constitute the “Subordination Provisions” with respect to the
Securities of such Series; and 
 (21) any other terms of such Securities and any deletions from or modifications or additions
to this Indenture in respect of such Securities. 
 The terms of the Securities of any Series may provide, without limitation,
that the Securities shall be authenticated and delivered by the Trustee on original issue from time to time upon telephonic or written order of persons designated in the Board Resolution, Officers’ Certificate or supplemental indenture, as the
case may be, pertaining to such Series of Securities (telephonic instructions to be promptly confirmed in writing by such person) and that such persons are authorized to determine, consistent with such Board Resolution, Officers’ Certificate or
supplemental indenture, such terms and conditions of the Securities of such Series as are specified in such Board Resolution, Officers’ Certificate or supplemental indenture. All Securities of any one Series need not be issued at the same time
and, if so provided by the Company as contemplated by this Section 301, a Series may be reopened from time to time without the consent of any Holders for issuances of additional Securities of such Series or to establish additional terms
of such Series of Securities. 

  
 16 

 If any of the terms of the Securities of any Series shall be established by action taken by
or pursuant to a Board Resolution, the Board Resolution shall be delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of such Series. 

 

	 	Section 302.	Currency; Denominations. 

The principal of, and any premium and interest on, the Securities shall be payable in Dollars. Unless otherwise provided in or pursuant to
this Indenture, Securities shall be issuable in registered form without coupons in denominations of $1,000 and any integral multiple thereof. 
  

	 	Section 303.	Execution, Authentication, Delivery and Dating. 

 Securities shall be executed on behalf of the Company by its Chairman, Vice Chairman, Chief Executive Officer, its President or one of its Vice Presidents and by its Treasurer, one of its Assistant
Treasurers, its Secretary or one of its Assistant Secretaries and may (but need not) have its corporate seal or a facsimile thereof reproduced thereon. The signature of any of these officers on the Securities may be manual or facsimile. 

Securities bearing the manual or facsimile signatures of individuals who were at any time the proper officers of the Company shall, 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 Securities or did not hold such offices at the date of such
Securities. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may deliver
Securities executed by the Company, to the Trustee for authentication and, provided that the Board Resolution and Officers’ Certificate or supplemental indenture or indentures with respect to such Securities referred to in
Section 301 and a Company Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order and subject to the provisions hereof and of such Securities shall
authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall be entitled to receive, and (subject to
Section 315(a) through Section 315(d) of the Trust Indenture Act) shall be fully protected in relying upon, an Opinion of Counsel to the following effect, which Opinion of Counsel may contain such assumptions, qualifications and
limitations as such counsel shall deem appropriate: 
 (a) the form or forms and terms of such Securities have
been established in conformity with Section 201 and Section 301 of this Indenture; 
 (b)
all conditions precedent set forth in Section 201, Section 301 and Section 303 of this Indenture to the authentication and delivery of such Securities have been complied with and that such Securities, when
completed by appropriate insertions (if applicable), executed by duly authorized officers of the Company, delivered by duly authorized officers of the Company to the Trustee for authentication pursuant to this Indenture, and authenticated and
delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with
their terms, except as enforcement thereof may be subject to or limited by bankruptcy, insolvency, reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent transfer or other similar laws relating to or affecting creditors’
rights generally, and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law). 
 If all the Securities of any Series are not to be issued at one time, it shall not be necessary to deliver an Opinion of Counsel at the time of issuance of each Security, but such opinion, with such
modifications as counsel shall deem appropriate, shall be delivered at or before the time of issuance of the first Security of such Series. After any such first delivery, any separate request by the Company that the Trustee authenticate Securities
of such Series for original issue will be deemed to be a certification by the Company that all conditions precedent provided for in this Indenture relating to authentication and delivery of such Securities continue to have been complied with.

  
 17 

 The Trustee shall not be required to authenticate or to cause an Authenticating Agent to
authenticate any Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner that is not reasonably acceptable
to the Trustee or if the Trustee, being advised by counsel, determines that such action may not lawfully be taken. 
 Each
Security shall be dated the date of its authentication. 
 No Security shall be entitled to any benefit under this Indenture or
be valid or obligatory for any purpose, unless there appears on such Security a certificate of authentication substantially in the form provided for in Section 202 or Section 612 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 Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

  

	 	Section 304.	Temporary Securities. 

Pending the preparation of definitive Securities, the Company may execute and deliver to the Trustee and, upon Company Order, the Trustee
shall authenticate and deliver, in the manner provided in Section 303, temporary Securities in lieu thereof which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially
of the tenor of the definitive Securities in lieu of which they are issued, in registered form, without coupons, and with such appropriate insertions, omissions, substitutions and other variations as the officers of the Company executing such
Securities may determine, as conclusively evidenced by their execution of such Securities. Such temporary Securities may be in global form. 
 Except in the case of temporary Securities in global form, which shall be exchanged in accordance with the provisions set forth in this Indenture or the provisions established pursuant to
Section 301, if temporary Securities are issued, the Company shall cause definitive Securities to be prepared without unreasonable delay. Except as otherwise provided in or pursuant to this Indenture, after the preparation of definitive
Securities of the same Series and containing terms and provisions that are identical to those of any temporary Securities, such temporary Securities shall be exchangeable for such definitive Securities upon surrender of such temporary Securities at
an Office or Agency for such Securities, without charge to any Holder thereof. Except as otherwise provided in or pursuant to this Indenture, upon surrender for cancellation of any one or more temporary Securities, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Securities of authorized denominations of the same Series and containing identical terms and provisions. Unless otherwise provided in or pursuant to
this Indenture with respect to a temporary global Security, until so exchanged the temporary Securities of any Series shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of such Series. 

 

	 	Section 305.	Registration, Transfer and Exchange. 

 With respect to the Securities of each Series, if any, the Company shall cause to be kept a register (each such register being herein sometimes referred to as the “Security Register”) at
an Office or Agency for such Series in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the Securities of such Series and of transfers of the Securities of such Series. Such Office
or Agency shall be the “Security Registrar” for that Series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the initial Security Registrar for each Series of Securities shall be as specified in
the penultimate paragraph of Section 1002. The Company shall have the right to remove and replace from time to time the Security Registrar for any Series of Securities; provided that no such removal or replacement shall be effective
until a successor Security Registrar with respect to such Series of Securities shall have been appointed by the Company and shall have accepted such appointment. In the event that the Trustee shall not be or shall cease to be Security Registrar with
respect to a Series of Securities, it shall have the right to examine the Security Register for such Series at all reasonable times. There shall be only one Security Register for each Series of Securities. 

Except as otherwise provided in or pursuant to this Indenture, upon surrender for registration of transfer of any Security of any Series
at any Office or Agency for such Series, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same Series denominated as authorized in
or pursuant to this Indenture, of a like aggregate principal amount bearing a number not contemporaneously outstanding and containing identical terms and provisions. 

  
 18 

 Except as otherwise provided in or pursuant to this Indenture, at the option of the Holder,
Securities of any Series may be exchanged for other Securities of the same Series containing identical terms and provisions, in any authorized denominations, and of a like aggregate principal amount, upon surrender of the Securities to be exchanged
at any Office or Agency for such Series. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities that the Holder making the exchange is entitled to receive.

 Notwithstanding the foregoing, except as otherwise provided in or pursuant to this Indenture, the global Securities of any
Series shall be exchangeable for definitive certificated Securities of such Series only if (i) the Depositary for such global Securities notifies the Company that it is unwilling or unable to continue as a Depositary for such global Securities
or at any time the Depositary for such global Securities ceases to be a clearing agency registered as such under the Exchange Act, if so required by applicable law or regulation, and no successor Depositary for such Securities shall have been
appointed within 90 days of such notification or of the Company becoming aware of the Depositary’s ceasing to be so registered, as the case may be, (ii) the Company, in its sole discretion, determines that the Securities of such Series
shall no longer be represented by one or more global Securities and executes and delivers to the Trustee a Company Order to the effect that such global Securities shall be so exchangeable, or (iii) an Event of Default has occurred and is
continuing with respect to such Securities. 
 If the beneficial owners of interests in a global Security are entitled to
exchange such interests for definitive Securities as the result of an event described in clause (i), (ii) or (iii) of the preceding paragraph, then without unnecessary delay, but in any event not later than the earliest date on which such
interests may be so exchanged, the Company shall deliver to the Trustee definitive Securities in such form and denominations as are required by or pursuant to this Indenture, and of the same Series, containing identical terms and in aggregate
principal amount equal to the principal amount of such global Security, executed by the Company. On or after the earliest date on which such interests may be so exchanged, such global Security shall be surrendered from time to time by the Depositary
(or its custodian) as shall be specified in the Company Order with respect thereto (which the Company agrees to deliver), and in accordance with instructions given to the Trustee and the Depositary (which instructions shall be in writing but need
not be contained in or accompanied by an Officers’ Certificate or be accompanied by an Opinion of Counsel), as shall be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities as described above without charge. The Trustee shall authenticate and make available for delivery, in exchange for each portion of such surrendered global Security, a like aggregate principal
amount of definitive Securities of the same Series of authorized denominations and of like tenor as the portion of such global Security to be exchanged, which shall be in the form of Registered Securities, and which shall be in such denominations
and registered in such names, as shall be specified by the Depositary; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of the same Series to be
redeemed and ending on the relevant Redemption Date. Promptly following any such exchange in part, such global Security shall be returned by the Trustee to such Depositary (or its custodian) or such other Depositary (or its custodian) referred to
above in accordance with the instructions of the Company referred to above, and the Trustee shall endorse such global Security to reflect the decrease in the principal amount thereof resulting from such exchange. If a Security is issued in exchange
for any portion of a global Security after the close of business at the Office or Agency for such Security where such exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or
Agency on the next Interest Payment Date, or (ii) any Special Record Date for such Security and before the opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may
be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may be, in respect of such Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only
to the Person to whom interest in respect of such portion of such global Security shall be payable in accordance with the provisions of this Indenture. 
 All Securities issued upon any registration of transfer or exchange of Securities shall 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 Securities surrendered upon such registration of transfer or exchange. 

  
 19 

 Every Security presented or surrendered for registration of transfer or for exchange or
redemption shall (if so required by the Company or the Security Registrar for such Security) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar for such Security
duly executed by the Holder thereof or his attorney duly authorized in writing. 
 No service charge shall be made for any
registration of transfer or exchange of Securities, or any redemption or repayment of Securities, or any conversion or exchange of Securities for other types of securities or property, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, Section 905 or Section 1107, or
upon surrender in part of any Security for conversion or exchange into Common Stock or other securities or property pursuant to its terms, in each case not involving any transfer. 

Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required (i) to issue, register the transfer
of or exchange any Securities during a period beginning at the opening of business 15 days before the day of the selection for redemption of Securities of like tenor and terms and of the same Series under Section 1103 and ending at the
close of business on the day of such selection, or (ii) to register the transfer of or exchange any Security, or portion thereof, so selected for redemption, except in the case of any Security to be redeemed in part, the portion thereof not to
be redeemed. 
 The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any
restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Security (including any transfers between or among Depositary participants or beneficial owners of interests in any
global Security) 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 shall have
any responsibility for any actions taken or not taken by the Depositary. 
  

	 	Section 306.	Mutilated, Destroyed, Lost and Stolen Securities. 

 If any mutilated Security is surrendered to the Trustee, subject to the provisions of this Section 306, the Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a new Security of the same Series 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 Security, 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 Security has been acquired by a bona fide purchaser, the Company shall execute and, upon the
Company’s request the Trustee shall authenticate and deliver, in exchange for or in lieu of any such destroyed, lost or stolen Security, a new Security of the same Series containing identical terms and of like principal amount and bearing a
number not contemporaneously outstanding. 
 Notwithstanding the foregoing provisions of this Section 306, in case
the outstanding principal balance of any mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 

Upon the issuance of any new Security 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 Security issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute a separate obligation of the Company, whether or not the destroyed, lost or stolen
Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such Series duly issued hereunder. 

  
 20 

 The provisions of this Section, as amended or supplemented pursuant to this Indenture with
respect to particular Securities or generally, shall (to the extent lawful) be exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen
Securities. 
  

	 	Section 307.	Payment of Interest; Rights to Interest Preserved. 

 Unless otherwise provided in or pursuant to this Indenture, any interest on any Security that shall be payable, and are punctually paid or duly provided for, on any Interest Payment Date shall be paid to
the Person in whose name such Security (or one or more Predecessor Securities) is registered as of the close of business on the Regular Record Date for such interest. 
 Unless otherwise provided in or pursuant to this Indenture, any interest on any Security that shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such
Security (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the
Company, at its election in each case, as provided in clause (1) or (2) below: 
 (1) The Company may elect to make
payment of any Defaulted Interest to the Person in whose name such Security (or a Predecessor Security thereof) shall be registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in
the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on such Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an
amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit 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 shall fix or cause to be fixed a Special Record Date for the payment of such Defaulted Interest, which
shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Company (or, upon the written request of the
Company, the Trustee in the name and at the expense of the Company), shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to the Holder of such Security
(or a Predecessor Security thereof) at the Holder’s address as it appears in the Security 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 Dallas, Texas, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the
proposed payment of such Defaulted Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Security (or a Predecessor Security thereof) shall be registered
at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 
 (2)
The 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 Security 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 pursuant to this Clause, such payment shall be deemed practicable by the Trustee. 
 Unless otherwise provided in or pursuant to this Indenture or the Securities of any particular Series, at the option of the Company, interest on Securities that bear interest may be paid by mailing a
check to the address of the Person entitled thereto as such address shall appear in the Security Register or by transfer to an account maintained by the payee with a bank located in the United States of America. 

  
 21 

 Subject to the foregoing provisions of this Section and Section 305, each
Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 

 

	 	Section 308.	Persons Deemed Owners. 

Prior to due presentment of a Security 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 Security is registered in the Security Register as the owner of such Security for the purpose of receiving payment of principal of, any premium and (subject to Section 305 and
Section 307) interest on such Security and for all other purposes whatsoever, whether or not any payment with respect to such Security shall be overdue, and neither the Company, the Trustee or any agent of the Company or the Trustee
shall be affected by notice to the contrary. 
 No holder of any beneficial interest in any global Security held on its behalf
by a Depositary shall have any rights under this Indenture with respect to such global Security, and such Depositary may be treated by the Company, the Trustee, and any agent of the Company or the Trustee as the owner of such global Security for all
purposes whatsoever. None of the Company, the Trustee, any Paying Agent or the Security 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 Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 

Notwithstanding the foregoing, nothing herein shall prevent the Company, the Trustee, any Paying Agent or the Security 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 Security or impair, as between such Depositary and the owners of beneficial interests in such
global Security, the operation of customary practices governing the exercise of the rights of such Depositary (or its nominee) as the Holder of such global Security. 
  

	 	Section 309.	Cancellation. 

 All
Securities surrendered for payment, redemption, registration of transfer, exchange or conversion or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such
Securities, as well as Securities surrendered directly to the Trustee for any such purpose, shall be cancelled promptly by the Trustee. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and
delivered hereunder which the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be cancelled promptly by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled
as provided in this Section, except as expressly permitted by or pursuant to this Indenture. All cancelled Securities held by the Trustee shall be disposed of in accordance with its procedure for the disposition of cancelled Securities, and the
Trustee upon the written request of the Company shall deliver to the Company a certificate of such disposition, or if directed by a Company Order returned to the Company. 

 

	 	Section 310.	Computation of Interest. 

Except as otherwise provided in or pursuant to this Indenture or in the Securities of any Series, interest on the Securities shall be
computed on the basis of a 360-day year of twelve 30-day months. 
 ARTICLE FOUR 

SATISFACTION AND DISCHARGE OF INDENTURE 
  

	 	Section 401.	Satisfaction and Discharge. 

 Unless, pursuant to Section 301, the provisions of this Section 401 shall not be applicable with respect to the Securities of any Series, upon the direction of the Company by a
Company Order, this Indenture shall cease to be of further effect with respect to any Series of Securities specified in such Company Order, and the Trustee, on receipt of a Company Order, at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture as to such Series, when 

  
 22 

 (1) either 

(a) all Securities of such Series theretofore authenticated and delivered (other than (i) Securities of such Series
that have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 306 and (ii) Securities of such Series 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 1003) have been delivered to the Trustee for cancellation; or 

(b) all Securities of such Series and not theretofore 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, money in Dollars in an amount sufficient to pay and discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, including the principal of, and any premium and interest on
such Securities, to the date of such deposit (in the case of Securities which have become due and payable) or to the Maturity thereof, as the case may be; 
 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to the Outstanding Securities of such Series; and 

(3) the Company has delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such Series have been complied with. 
 In the event there are Securities of two or more Series Outstanding hereunder, the Trustee for the Series as to which the Indenture is to be discharged shall be required to execute an instrument
acknowledging satisfaction and discharge of this Indenture only if requested to do so with respect to Securities of such Series as to which it is Trustee and if the other conditions thereto are met. 

Notwithstanding the satisfaction and discharge of this Indenture with respect to any Series of Securities, the obligations of the Company
to the Trustee under Section 607 and, if money shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations of the Company and the Trustee with respect to the Securities of
such Series under Section 305, Section 306, Section 403, Section 404, Section 1002 and Section 1003, any rights of Holders of the Securities of such Series (unless otherwise
provided pursuant to Section 301 with respect to the Securities of such Series) to require the Company to repurchase or repay, and any rights of Holders of the Securities of such Series (unless otherwise provided pursuant to
Section 301 with respect to the Securities of such Series) to convert or exchange, and the obligations of the Company to convert or exchange, such Securities into Common Stock or other securities or property, shall survive. 

 

	 	Section 402.	Defeasance and Covenant Defeasance. 

 (1) Unless, pursuant to Section 301, either or both of (i) defeasance of the Securities of or within a Series under clause (2) of this Section 402 or (ii) covenant
defeasance of the Securities of or within a Series under clause (3) of this Section 402 shall not be applicable with respect to the Securities of such Series, then such provisions, together with the other provisions of this
Section 402 (with such modifications thereto as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to such Securities, and the Company may at its option by Board Resolution, at any
time, with respect to the Securities of or within such Series, elect to have Section 402(2) or Section 402(3) be applied to such Outstanding Securities upon compliance with the conditions set forth below in this
Section 402. Unless otherwise specified pursuant to Section 301 with respect to the Securities of any Series, defeasance under clause (2) of this Section 402 and covenant defeasance under clause (3) of

  
 23 

 
this Section 402 may be effected only with respect to all, and not less than all, of the Outstanding Securities of any Series. To the extent that the terms of any Security established
in or pursuant to this Indenture permit the Company or any Holder thereof to extend the date on which any payment of principal of, or premium, if any, or interest, if any, on, such Security is due and payable, then unless otherwise provided pursuant
to Section 301, the right to extend such date shall terminate upon defeasance or covenant defeasance, as the case may be. 
 (2) Upon the Company’s exercise of the above option applicable to this Section 402(2) with respect to any Securities of or within a Series, the Company shall be deemed to have been
discharged from its obligations with respect to such Outstanding Securities on the date the conditions set forth in clause (4) of this Section 402 are satisfied (hereinafter, “defeasance”). For this purpose, such
defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding Securities, which shall thereafter be deemed to be “Outstanding” only for the purposes of clause
(5) of this Section 402 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 Securities and this Indenture
insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder:
(i) the rights of Holders of such Outstanding Securities to receive, solely (except as provided in clause (ii) below) from the trust fund described in clause (4)(a) of this Section 402 and as more fully set forth in this
Section 402 and Section 403, payments in respect of the principal of (and premium, if any) and interest, if any, on, such Securities when such payments are due, (ii) the obligations of the Company and the Trustee with
respect to such Securities under Section 305, Section 306, Section 1002 and Section 1003, any rights of Holders of the Securities of such Series (unless otherwise provided pursuant to
Section 301 with respect to the Securities of such Series) to require the Company to repurchase or repay, and any rights of Holders of such Securities (unless otherwise provided pursuant to Section 301 with respect to the
Securities of such Series) to convert or exchange, and the obligations of the Company to convert or exchange, such Securities into Common Stock or other securities or property, (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (iv) this Section 402 and Section 403 and Section 404. The Company may exercise its option under this Section 402(2) notwithstanding the prior exercise of its option under
Section 402(3) with respect to such Securities. 
 (3) Upon the Company’s exercise of the above option
applicable to this Section 402(3) with respect to any Securities of or within a Series, the Company shall be released from its obligations under clauses (ii) and (iii) of Section 1004 and under
Section 1005, Section 1006 and Section 1007 and any other covenant applicable to such Securities with respect to such Securities shall cease to be applicable to such Securities on and after the date the conditions
set forth in clause (4) of this Section 402 are satisfied (hereinafter, “covenant defeasance”), and such Securities shall thereafter be deemed to be not “Outstanding” for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any thereof) in connection with any such covenant, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant
defeasance means that with respect to such Outstanding Securities, the Company may omit to comply with, and shall 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 shall not constitute a default or an Event of Default under Section 501(4) or Section 501(8) or otherwise, as the case may be, but, except as specified above, the remainder of this Indenture and such
Securities shall be unaffected thereby. 
 (4) The following shall be the conditions to application of clause (2) or
(3) of this Section 402 to any Outstanding Securities of or within a Series: 
 (a) The Company
shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements of Section 608 who shall agree to comply with the provisions of this Section 402 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 of such Securities, (1) an amount in Dollars or (2) 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 premium, if any) and interest, if any, on
such Securities, money or (3) a combination thereof, in any case, in an amount, sufficient, without 

  
 24 

 
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 shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (y) the principal of (and premium, if any) and interest, if any, on, such Outstanding Securities on
the Stated Maturity of such principal or installment of principal or interest or the applicable Redemption Date, as the case may be, and (z) any mandatory sinking fund payments or analogous payments applicable to such Outstanding Securities on
the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities. 
 (b) Such defeasance or covenant defeasance shall 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 Securities shall have occurred and be continuing on the date of such deposit, and, solely in the case of defeasance under Section 402(2), no Event
of Default with respect to such Securities under clause (5) or (6) of Section 501 or event which with notice or lapse of time or both would become an Event of Default with respect to such Securities under clause (5) or
(6) of Section 501 shall 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 defeasance under
Section 402(2) shall not be deemed satisfied until the expiration of such period). 
 (d) In the case
of defeasance pursuant to Section 402(2), the Company shall have delivered to the Trustee an opinion of independent counsel reasonably acceptable to the Trustee stating that (x) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling, or (y) 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
shall confirm that, the Holders of such Outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such 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 defeasance had not occurred; or, in the case of covenant defeasance pursuant to Section 402(3), the Company shall have delivered to the Trustee an opinion of independent counsel
reasonably acceptable to the Trustee to the effect that the Holders of such Outstanding Securities 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. 
 (e) The Company shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the defeasance or covenant defeasance, as the
case may be, under this Indenture have been complied with. 
 (f) If the moneys or Government Obligations or
combination thereof, as the case may be, deposited under clause (a) above are sufficient to pay the principal of, and premium, if any, and interest, if any, on, such Securities provided such Securities are redeemed on a particular Redemption
Date, the Company shall have given the Trustee irrevocable instructions to redeem such Securities on such date and to provide notice of such redemption to Holders as provided in or pursuant to this Indenture. 

(g) No event or condition will exist pursuant to the terms of Section 301(20) that would prevent the Company
from making payments of principal and premium, if any, and interest on the Securities at the date of the irrevocable deposit referred to above. 
 (h) Notwithstanding any other provisions of this Section 402(4), such defeasance or covenant defeasance shall be effected in compliance with any additional or substitute terms, conditions or
limitations that may be imposed on the Company in connection therewith pursuant to Section 301. 

  
 25 

 (5) Subject to the provisions of the last paragraph of Section 1003, all money
and Government Obligations (or other property as may be provided pursuant to Section 301) (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee—collectively for purposes of this
Section 402(5) and Section 403, the “Trustee”) pursuant to clause (4)(a) of Section 402 in respect of any Outstanding Securities of any Series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities 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 such Securities of all sums due and to become due thereon in respect of principal (and premium, if any) and interest but such money need not be segregated from other funds except to the extent required by
law. 
 The Company shall pay and indemnify the Trustee against any tax, fee or other charge, imposed on or assessed against the
Government Obligations deposited pursuant to this Section 402 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 such Outstanding
Securities. 
 Anything in this Section 402 to the contrary notwithstanding, the Trustee shall deliver or pay to the
Company from time to time upon Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in clause (4)(a) of this Section 402 which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect a defeasance or covenant defeasance,
as applicable, in accordance with this Section 402. 
  

	 	Section 403.	Application of Trust Money. 

 Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations deposited with the Trustee pursuant to Section 401 or Section 402
shall be held in trust and applied by it, in accordance with the provisions of the Securities subject to discharge under Section 401 or defeasance or covenant defeasance under Section 402, 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, premium 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 404.	Reinstatement. 

 If the
Trustee (or other qualifying trustee appointed pursuant to Section 402(4)(a)) or any Paying Agent is unable to apply any moneys or Government Obligations deposited pursuant to Section 401(1) or Section 402(4)(a)
to pay any principal of or premium, if any, or interest, if any, on, the Securities of any Series 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 Securities of such Series shall 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 premium, if any, and interest, if any, on the Securities of such Series as contemplated by Section 401 or Section 402 as the
case may be, and Section 403; provided, however, that if the Company makes any payment of the principal of or premium, if any, or interest if any, on the Securities of such Series following the reinstatement of its obligations as
aforesaid, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the funds held by the Trustee (or other qualifying trustee) or Paying Agent. 

 

	 	Section 405.	Effect on Subordination Provisions. 

 Unless otherwise expressly provided pursuant to Section 301 with respect to the Securities of any Series, the provisions of Article Fifteen hereof, insofar as they pertain to the
Securities of such Series, and the Subordination Provisions of the Securities of such Series established pursuant to Section 301(20) are hereby expressly made subject to the provisions for, and to the right of the Company to effect, the
satisfaction and discharge of all of the Securities of such Series as set forth in and pursuant to Section 401 and the provisions for, and to the right of the Company to effect, defeasance and covenant defeasance of all the Securities of
such Series or designated 

  
 26 

 
Securities within such Series as set forth in and pursuant to Section 402. As a result, and anything herein to the contrary notwithstanding, if the Company complies with the
provisions of Section 401 to effect the satisfaction and discharge of all of the Securities of a Series or complies with the provisions of Section 402 to effect the defeasance or covenant defeasance of designated Securities
within a Series (which may be all of the Securities of such Series), upon the effectiveness of such satisfaction and discharge pursuant to Section 401 with respect to all of the Securities of such Series or of defeasance or covenant
defeasance pursuant to Section 402 with respect to the Securities within such Series designated for such defeasance or covenant defeasance, all of the Securities of such Series, in the case of satisfaction and discharge pursuant to
Section 401, or, in the case of defeasance or covenant defeasance pursuant to Section 402, the Securities of such Series as to which defeasance or covenant defeasance, as the case may be, shall have become effective shall
thereupon cease to be so subordinated in right of payment to the Senior Indebtedness and shall no longer be subject to the provisions of Article Fifteen or the Subordination Provisions of such Securities established pursuant to
Section 301(20) and, without limitation to the foregoing, all moneys, Government Obligations and other securities or property deposited with the Trustee (or other qualifying trustee) in trust in connection with such satisfaction and
discharge, defeasance or covenant defeasance, as the case may be, and all proceeds therefrom may be applied to pay the principal of, and premium, if any, and interest, if any, on, such Securities as and when the same shall become due and payable
notwithstanding the provisions of Article Fifteen or such Subordination Provisions without regard to whether any or all of the Senior Indebtedness then outstanding shall have been paid or otherwise provided for. 

ARTICLE FIVE 

REMEDIES 
  

	 	Section 501.	Events of Default. 

“Events of Default,” wherever used in this Indenture with respect to Securities of any Series, means any one of the following
events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree, or order of any court or any order, rule, or regulation of any
administrative or governmental body) unless such event is specifically deleted or modified in or pursuant to the supplemental indenture, Board Resolution or Officers’ Certificate establishing such Series of Securities or the terms of the
Securities of such Series pursuant to this Indenture: 
 (1) default in the payment of any interest on any of the Securities of
such Series when such interest becomes due and payable, and continuance of such default for a period of 30 days; or 
 (2)
default in the payment of any principal of or premium, if any, on any of the Securities of such Series when due (whether at Maturity or otherwise and whether payable in cash or in shares of Common Stock or other securities or property); or

 (3) default in the deposit of any sinking fund payment or payment under any analogous provision when due with respect to any
of the Securities of such Series; or 
 (4) default in the performance, or breach, of any covenant or warranty of the Company in
this Indenture or any Security of such Series (other than a covenant or warranty for which the consequences of breach or nonperformance are addressed elsewhere in this Section 501 or a covenant or warranty which has expressly been
included in this Indenture, whether or not by means of a supplemental indenture, solely for the benefit of Securities of a Series other than such Series), and continuance of such default or breach (without such default or breach having been waived
in accordance of the provisions of this Indenture) for a period of 90 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal
amount of the Outstanding Securities of such Series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of Default” hereunder; or 

(5) 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 shall have continued unstayed and in
effect for a period of 60 consecutive days; or 

  
 27 

 (6) 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; or 
 (7) any other Event of Default provided in or pursuant to this Indenture with respect to Securities of such
Series. 
  

	 	Section 502.	Acceleration of Maturity; Rescission and Annulment. 

 Unless the supplemental indenture, Board Resolution or Officers’ Certificate establishing or evidencing the establishment of a Series of Securities or the terms of the Securities of a Series pursuant
to this Indenture shall provide otherwise, if an Event of Default (other than an Event of Default specified in clause (5) or (6) of Section 501) with respect to Securities of any Series occurs and is continuing, then either the
Trustee or the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such Series may declare the principal of all the Securities of such Series, or such lesser amount as may be provided for in the Securities of
such Series, and accrued and unpaid interest, if any, thereon to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by the Holders), and upon any such declaration such principal or such lesser amount,
as the case may be, and such accrued and unpaid interest shall become immediately due and payable. If an Event of Default specified in clause (5) or (6) of Section 501 occurs, then the principal amount of all of the Securities
of such Series Outstanding, or such lesser amount as may be provided for in the Securities of such Series, and accrued and unpaid interest, if any, on all Securities of all Series Outstanding shall become and be immediately due and payable without
any declaration or other act on the part of the Trustee or any Holder of the Securities of such Series. 
 At any time after the
occurrence of an Event of Default with respect to Securities of one or more Series and before a judgment or decree for payment of the money due has been obtained by the Trustee as provided below in this Article Five, the Holders of not
less than a majority in aggregate principal amount of the Outstanding Securities of all affected Series (voting as one class), by written notice to the Company and the Trustee may waive all defaults with respect to all affected Series, and may
rescind and annul the consequences of the Event of Default, if: 
 (1) the Company has paid or deposited with the Trustee a sum
of money sufficient to pay (or, to the extent that the terms of the Securities of such Series established pursuant to Section 301 expressly provide for payment to be made in shares of Common Stock or other securities or property, shares
of Common Stock or other securities or property, together with cash in lieu of fractional shares or securities, sufficient to pay) 
 (a) all overdue installments of any interest on any Securities of such Series that have become due otherwise than by such declaration of acceleration, 

(b) the principal of and any premium on any Securities of such Series which have become due otherwise than by such
declaration of acceleration and, to the extent permitted by applicable law, interest thereon at the rate or respective rates, as the case may be, provided for in or with respect to such Securities, 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 Securities, 
 (c) to the extent
permitted by applicable law, interest upon installments of any interest, if any, which have become due otherwise than by such declaration of acceleration at the rate or respective rates, as the case may be, provided for in or with respect to such
Securities, 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 Securities, and 
 (d) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due the Trustee
under Section 607; and 
 (2) all Events of Default with respect to Securities of all affected Series other than the
nonpayment of the principal of, or any premium and interest on, Securities of the affected Series that shall have become due solely by such acceleration, shall have been cured or waived as provided in Section 513. 

  
 28 

 No such rescission shall affect any subsequent default or impair any right consequent
thereon. 
 For all purposes under this Indenture, if a portion of the principal of any Original Issue Discount Securities shall
have been accelerated and declared due and payable pursuant to the provisions of this Indenture, then, from and after the date of such Event of Default, unless such Event of Default has been rescinded and annulled as provided above, the principal
amount of such Original Issue Discount Securities shall be deemed, for all purposes under this Indenture, to be such portion of the principal as shall be due and payable as a result of such acceleration, and the payment of such portion of the
principal as shall be due and payable as a result of such acceleration, together with interest, if any, on such portion and all other amounts owing under such Original Issue Discount Security, shall constitute payment in full of such Original Issue
Discount Securities. 
  

	 	Section 503.	Collection of Indebtedness and Suits for Enforcement by Trustee. 

 The Company covenants that if: 
 (1) default is made in the payment of any
interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, 
 (2)
default is made in the payment of the principal of (or premium, if any, on) any Security at its Maturity, or 
 (3) default is
made in the making or satisfaction of any sinking fund or analogous obligation when the same becomes due pursuant to the terms of any Security, 

the Company will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount then due and
payable with respect to such Securities, with interest upon the overdue principal, any premium and, to the extent permitted by applicable law, upon any overdue installments of interest at the rate or respective rates, as the case may be, provided
for or with respect to such Securities 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 Securities, subject, however, to any limitation on such obligation of the Company to
pay such amounts as shall be set forth in the supplemental indenture, Board Resolution or Officers’ Certificate establishing or evidencing the establishment of a Series of Securities or the terms of the Series of Securities of which such
Security is a part pursuant to this Indenture, and, in addition thereto, such further amount of money as shall 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 607. 
 If the Company
fails to pay the money it is required to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand of the Trustee, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the
collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree, and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in
the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated. 

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

 In case of any judicial proceeding relative to the Company (or any other obligor upon the Securities), its property or its creditors, the Trustee shall 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 shall be authorized to 

(1) to file and prove a claim for the whole amount, or such lesser amount as may be provided for in the Securities of such Series, of the
principal and any premium or interest owing and unpaid in respect of such Securities 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 Securities allowed in such judicial proceeding, and 
 (2) collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; 
 and any custodian, receiver, assignee, trustee, liquidator, sequestrator, or other similar official in any such judicial proceeding is authorized by each Holder of Securities to make such payments to the
Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders of Securities 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 607. 
 No provision of this
Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security any plan of reorganization, arrangement, adjustment, or composition affecting the Securities 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 505.	Trustee May Enforce Claims Without Possession of Securities. 

 All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production of such Securities in
any related proceeding, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall, 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 of the Securities in respect of which such judgment has been recovered. 

 

	 	Section 506.	Application of Money Collected.

	 	Section 507.	Limitation on Suits. 

 No
Holder of any Security of any Series shall 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:

 (1) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the
Securities of that Series; 
 (2) the Holders of not less than 25% in aggregate principal amount of the Outstanding Securities
of that Series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee under the Indenture; 
 (3) 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;

 (4) the Trustee for 60 days after its receipt of such notice, request, and offer of indemnity has failed to institute any
such proceeding; and 
 (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day
period by the Holders of a majority in principal amount of the Outstanding Securities of that Series; 
 it being understood and intended that
no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing 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 508.	Unconditional Right of Holders to Receive Principal, Premium and Interest. 

 Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and
(subject to Section 305 and Section 307) any interest on such Security on the respective Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and, in the case of any
Security that is convertible into or exchangeable for other securities or property, to convert or exchange, as the case may be, such Security in accordance with its terms), and to institute suit for the enforcement of any such payment and such
rights shall not be impaired without the consent of such Holder. 
  

	 	Section 509.	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 shall be restored severally and respectively to their former positions under this
Indenture and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 
  

	 	Section 510.	Rights and Remedies Cumulative. 

 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost, or stolen Securities in the last paragraph of Section 306, 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 shall, to the extent permitted by law, be cumulative and in addition to every other right and
remedy given under this Indenture or now or in the future existing at law or in equity or otherwise. The assertion or employment of any right or remedy under this Indenture, or otherwise, shall not prevent the concurrent assertion or employment of
any other appropriate right or remedy. 

  
 31 

	 	Section 511.	Delay or Omission Not Waiver. 

 No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default shall 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 512.	Control by Holders. 

 The
Holders of a majority in aggregate principal amount of the Outstanding Securities of any Series shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust
or power conferred on the Trustee, with respect to the Securities of such Series, provided that 
 (1) such direction shall not
be in conflict with any rule of law or with this Indenture or with the Securities of any Series, 
 (2) the Trustee may take any
other action deemed proper by the Trustee which is not inconsistent with such direction, and 
 (3) the Trustee shall have the
right to decline to follow any such direction if the Trustee in good faith shall, by a Responsible Officer or Officers of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability. 

 

	 	Section 513.	Waiver of Past Defaults. 

Subject to Section 502, the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of
any Series may on behalf of the Holders of all the Securities of such Series waive any past default under this Indenture with respect to such Series and its consequences, except a default (1) in the payment of the principal of, or any premium
or interest on, any Security of such Series, or (2) in respect of a covenant or provision of this Indenture which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of
such affected Series. 
 Upon any such waiver, such default shall cease to exist, and any Event of Default arising from such
default shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any consequent right. 

 

	 	Section 514.	Waiver of Usury, Stay or Extension Laws. 

 The Company covenants that (to the extent that it may lawfully do so) it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law or any usury law or any other law wherever enacted, now or at any time hereafter in force, which would prohibit or forgive the Company from paying all or any portion of the principal of or premium, if any, or interest, if any, on any
Securities as contemplated herein and therein or which may affect the covenants or the performance of this Indenture or the Securities; and the Company (to the extent that it may lawfully do so) expressly waives all benefit or advantage of any such
law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee or the Holders, but will suffer and permit the execution of every such power as though no such law had been enacted. 

  
 32 

	 	Section 515.	Undertaking for Costs. 

All parties to this Indenture agree, and each Holder of any Securities by his acceptance of such Securities shall be deemed to have
agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered, or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorney’s fees and expenses, against any party litigant in such suit, having
due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 515 shall 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 Securities of any Series, or to any suit instituted by any Holder for the enforcement of the payment of the principal
of (or premium, if any) or interest, if any, on any Securities on or after the Stated Maturity or Maturities expressed in such Securities (or, in the case of redemption, on or after the Redemption Date) or for the enforcement of the right, if any,

 ARTICLE SIX

 THE TRUSTEE 
  

	 	Section 601.	Duties of Trustee. 

 (1)
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

Directors may be sufficiently evidenced by a Board Resolution; 

  
 33

Certificate; 
 (4) Before the Trustee acts or refrains from acting, it may require an Officers’ Certificate or an Opinion
of Counsel or both. The Trustee will not be liable for any action it takes or omits to take in good faith in reliance on such Officers’ Certificate or Opinion of Counsel. The Trustee may consult with counsel and the written advice of such
counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon. The Trustee may act through its
attorneys and agents and will not be responsible for the misconduct or negligence of any agent appointed with due care. 
 (5)
the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by or pursuant to this Indenture at the request or direction of any of the Holders of Securities of any Series pursuant to this Indenture, unless such
Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction; 

(6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, bond, debenture or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit,
and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine, during business hours and upon reasonable notice, the books, records and premises of the Company, personally or by agent or attorney,

amount of the Outstanding Securities then outstanding delivered to the Corporate Trust Office of the Trustee and in the absence of such notice so delivered the Trustee may conclusively assume no Default exists. 

(11) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder; and

Within 90 days after the Trustee is notified of the occurrence of any default hereunder with respect to the Securities of any Series, the
Trustee shall transmit by mail to all Holders of Securities of such Series entitled to receive reports pursuant to Section 703(3), notice of such default hereunder known to the Trustee, unless such default shall have been cured or
waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any), or interest, if any, on, any Security of such Series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee or a trust committee of directors and/or Responsible Officers of the Trustee in good faith determine that the withholding of such notice is in the best interest of the Holders of Securities of such
Series; and provided, further, that in the case of any default of the character specified in Section 501(4) or Section 501(8) with respect to Securities of such Series, no such notice to Holders shall be given until at least
30 days after the occurrence thereof. For the purpose of this Section, the term “default” means any event that is, or after notice or lapse of time or both would become, an Event of Default with respect to Securities of such Series.

  

	 	Section 604.	Not Responsible for Recitals or Issuance of Securities. 

 The recitals contained herein and in the Securities, except the Trustee’s certificate of authentication, shall be taken as the statements of the Company and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Securities, except that the Trustee represents that it is duly authorized to execute and
deliver this Indenture, authenticate the Securities and perform its obligations hereunder and that the statements made by it in a Statement of Eligibility on Form T-1 supplied to the Company are true and accurate, subject to the qualifications set
forth therein. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of the Securities or the proceeds thereof. The Trustee will not be responsible for and makes no representation as to the
validity or adequacy of this Indenture or the Securities, it shall not be accountable for the Company’s use of the proceeds from the Securities or any money paid to the Company or upon the Company’s direction under any provision hereof, it
will not be responsible for the use or application of any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or any statement in the Notes or any other document in connection
with the sale of the Securities or pursuant to this Indenture other than its certificate of authentication. 
  

	 	Section 605.	May Hold Securities. 

 The
Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other Person that may be an agent of the Trustee or the Company, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject
to Section 310(b) and Section 311 of the Trust Indenture Act, may otherwise deal with the Company with the same rights that it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other Person.

  

	 	Section 606.	Money Held in Trust. 

Except as provided in Section 403 and Section 1003, money held by the Trustee in trust hereunder need not be
segregated from other funds except to the extent required by law and shall be held uninvested. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company.

  

	 	Section 607.	Compensation and Reimbursement. 

 The Company agrees: 
 (1) to pay to the Trustee from time to time reasonable
compensation for all services rendered by the Trustee hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 

  
 35 

 (2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request
for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except
any such expense, disbursement or advance as may be attributable to the Trustee’s negligence or bad faith; and 
 (3) to
indemnify each of the Trustee or any predecessor Trustee and their agents for, and to hold them harmless against, any loss, liability or reasonable expense (including, without limitation, the reasonable fees and disbursements of the Trustee’s
agents, legal counsel, accountants and experts) and including taxes (other than taxes based upon, measured by or determined by the income of the Trustee), incurred without negligence or bad faith on their part, arising out of or in connection with
the acceptance or administration of the trust or trusts hereunder, including the reasonable costs and expenses of defending themselves against any claim (whether asserted by the Company, or any Holder or any other Person) or liability in connection
with the exercise or performance of any of their powers or duties hereunder, or in connection with enforcing the provisions of this Section, except to the extent that any such loss, liability or expense was due to the Trustee’s negligence or
bad faith. 
 As security for the performance of the obligations of the Company under this Section, the Trustee shall have a
lien prior to the Securities of any Series upon all property and funds held or collected by the Trustee as such, except funds held in trust for the payment of principal of, or premium or interest on Securities. Such lien will survive the
satisfaction and discharge hereof. 
 Any compensation or expense incurred by the Trustee after a default specified by
Section 501(5) or Section 501(6) is intended to constitute an expense of administration under any then applicable bankruptcy or insolvency law. “Trustee” for purposes of this Section 607 shall include
any predecessor Trustee, but the negligence or bad faith of any Trustee shall not affect the rights of any other Trustee under this Section 607. The provisions of this Section 607 shall, to the extent permitted by law,
survive any termination of this Indenture (including, without limitation, termination pursuant to any Bankruptcy Laws) and the resignation or removal of the Trustee. 
  

	 	Section 608.	Corporate Trustee Required; Eligibility. 

 (1) There shall at all times be a Trustee hereunder that is a corporation, organized and doing business under the laws of the United States of America, any state thereof or the District of Columbia,
eligible under Section 310(a)(1) of the Trust Indenture Act to act as trustee under an indenture qualified under the Trust Indenture Act and that has a combined capital and surplus (computed in accordance with Section 310(a)(2) of the
Trust Indenture Act) of at least $50,000,000 subject to supervision or examination by federal or state authority. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article. 
 (2) The following indenture shall be considered
specifically described herein for purposes of clause (i) of the proviso contained in Section 310(b)(1) of the Trust Indenture Act: Senior Debt Indenture dated as of June 25, 2014 between the Company and Wells Fargo Bank, National
Association, as trustee; and, pursuant to Section 310(b)(1)(C)(i) of the Trust Indenture Act, unless otherwise ordered by the Commission, an event of default by the Company under this Indenture will not disqualify the Trustee under this
Indenture because it is the trustee under such other indenture. 
  

	 	Section 609.	Resignation and Removal; Appointment of Successor. 

 (1) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article Six shall become effective until the acceptance of appointment by the successor
Trustee pursuant to Section 610. 
 (2) The Trustee may resign at any time with respect to the Securities of one or
more Series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee within 30 days after the giving of such notice of
resignation, the resigning Trustee may, at the Company’s expense, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to such Series. 

  
 36 

 (3) The Trustee may be removed at any time with respect to the Securities of any Series by
Act of the Holders of a majority in principal amount of the Outstanding Securities of such Series, delivered to the Trustee and the Company. 
 (4) If at any time: 
 (a) the Trustee shall fail to comply with the
obligations imposed upon it under Section 310(b) of the Trust Indenture Act with respect to Securities of any Series after written request therefor by the Company or any Holder of a Security of such Series who has been a bona fide Holder
of a Security of such Series for at least six months, or 
 (b) the Trustee shall cease to be eligible under
Section 608 and shall fail to resign after written request therefor by the Company or any such Holder, or 
 (c) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or
control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, 
 then, in any such case,
(i) the Company, by or pursuant to a Board Resolution, may remove the Trustee with respect to all Securities or the Securities of such Series, or (ii) subject to Section 315(e) of the Trust Indenture Act, any Holder of a Security who
has been a bona fide Holder of a Security of such Series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities
of such Series and the appointment of a successor Trustee or Trustees. 
 (5) If the Trustee shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more Series, the Company, by or pursuant to a Board Resolution, shall promptly appoint a successor Trustee or Trustees
with respect to the Securities of that or those Series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such Series and that at any time there shall be only one Trustee
with respect to the Securities of any particular Series) and shall comply with the applicable requirements of Section 610. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a
successor Trustee with respect to the Securities of any Series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such Series delivered to the Company and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 610, become the successor Trustee with respect to the Securities of such Series and to that extent
supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any Series shall have been so appointed by the Company or the Holders of Securities and accepted appointment in the manner required
by Section 610, any Holder of a Security who has been a bona fide Holder of a Security of such Series 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 Securities of such Series. 
 (6) The Company shall give notice of
each resignation and each removal of the Trustee with respect to the Securities of any Series and each appointment of a successor Trustee with respect to the Securities of any Series by mailing written notice of such event by first-class mail,
postage prepaid, to the Holders of Securities, if any, of such Series as their names and addresses appear in the Security Register. Each notice shall include the name of the successor Trustee with respect to the Securities of such Series and the
address of its Corporate Trust Office. 
  

	 	Section 610.	Acceptance of Appointment by Successor. 

 (1) Upon the appointment hereunder of any successor Trustee with respect to all Securities, such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and the retiring
Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties hereunder of the retiring Trustee; but, on the request of the Company or such 

  
 37 

 
successor Trustee, such retiring Trustee, upon payment of its charges, shall execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the
retiring Trustee and, subject to Section 1003, shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, subject nevertheless to its claim, if any, provided for in
Section 607. 
 (2) Upon the appointment hereunder of any successor Trustee with respect to the Securities of one or
more (but not all) Series, the Company, the retiring Trustee and such successor Trustee shall execute and deliver an indenture supplemental hereto wherein each successor Trustee shall accept such appointment and which (i) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, such successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those Series to which the
appointment of such successor Trustee relates, (ii) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts
and duties of the retiring Trustee with respect to the Securities of that or those Series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee, and (iii) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such
Trustees co-trustees of the same trust, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee and that no Trustee shall 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 shall become
effective to the extent provided therein, such retiring Trustee shall have no further responsibility for the exercise of rights and powers or for the performance of the duties and obligations vested in the Trustee under this Indenture with respect
to the Securities of that or those Series to which the appointment of such successor Trustee relates other than as hereinafter expressly set forth, and such successor Trustee, without any further act, deed or conveyance, shall become vested with all
the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those Series to which the appointment of such successor Trustee relates; but, on request of the Company or such successor Trustee, such retiring
Trustee, upon payment of its charges with respect to the Securities of that or those Series to which the appointment of such successor relates and subject to Section 1003 shall 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 Securities of that or those Series to which the appointment of such successor Trustee relates, subject to
its claim, if any, provided for in Section 607. 
 (3) Upon request of any Person appointed hereunder as a successor
Trustee, the Company shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (1) or (2) of this Section, as the case
may be. 
 (4) No Person shall accept its appointment hereunder as a successor Trustee unless at the time of such acceptance
such successor Person shall be qualified and eligible under this Article. 
  

	 	Section 611.	Merger, Conversion, Consolidation or Succession to Business. 

 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall
be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder (provided that such corporation shall otherwise be qualified and eligible under
this Article), without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall 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 Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities. In case any Securities shall not have been authenticated by
such predecessor Trustee, any such successor Trustee may authenticate and deliver such Securities in either its own name or that of its predecessor Trustee.

	 	Section 612.	Appointment of Authenticating Agent. 

 The Trustee may appoint one or more Authenticating Agents acceptable to the Company with respect to one or more Series of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of that or those Series issued upon original issue, exchange, registration of transfer, partial redemption, partial repayment, partial conversion or exchange for Common Stock or other securities or property, or pursuant to
Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. 
 Each Authenticating Agent
shall be reasonably acceptable to the Company and, except as provided in or pursuant to this Indenture, shall at all times be a corporation that would be permitted by the Trust Indenture Act to act as trustee under an indenture qualified under the
Trust Indenture Act, is authorized under applicable law and by its charter to act as an Authenticating Agent and has a combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least
$50,000,000. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Section. 

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust business of an Authenticating Agent,
shall be the successor of such Authenticating Agent hereunder, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating
Agent. 
 An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and 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 shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent that shall be acceptable to the Company and shall mail written notice of such
appointment by first-class mail, postage prepaid, to all Holders of Securities, if any, of the Series with respect to which such Authenticating Agent shall serve, as their names and addresses appear in the Security Register. Any successor
Authenticating Agent, upon acceptance of its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of this Section 612. 
 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 shall be entitled to be reimbursed for such payments, subject to the provisions of
Section 607. 
 The provisions of Section 308, Section 604 and Section 605 shall
be applicable to each Authenticating Agent. 
 If an Authenticating Agent is appointed with respect to one or more Series of
Securities pursuant to this Section, the Securities of such Series 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 Securities of the Series designated herein referred to in the within-mentioned Indenture.

writing (which writing need not be accompanied by or contained in an Officers’ Certificate of the Company), shall appoint in accordance with this Section an Authenticating Agent having an office in a Place of Payment designated by the Company
with respect to such Series of Securities.

	 	Section 1001.	Payment of Principal, Premium, Interest. 

 The Company covenants and agrees for the benefit of the Holders of the Securities of each Series that it will duly and punctually pay the principal of, any premium and interest on the Securities of such

	 	Section 1002.	Maintenance of Office or Agency. 

 The Company shall maintain in each Place of Payment for any Series of Securities an Office or Agency where Securities of such Series may be presented or surrendered for payment, where Securities of such
Series may be surrendered for registration of transfer or exchange, where Securities of such Series that are convertible or exchangeable may be surrendered for conversion or exchange, and where notices and demands to or upon the Company in respect
of the Securities of such Series relating thereto and this Indenture may be served, provided that, if (i) the City of Dallas, Texas, is a Place of Payment for the Securities of any Series, (ii) there shall be another Place of Payment in
the United States of America for such Securities in addition to the City of Dallas, Texas, and (iii) all Securities of such Series are originally issued solely in the form of one or more permanent global Securities, then the Company shall not
be required to maintain any such office or agency in the City of Dallas, Texas, unless and until all or any portion of such global Securities shall be exchanged for or otherwise issued as definitive certificated Securities of such Series as
contemplated by the last paragraph of this Section 1002. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such Office or Agency. If at any time the Company shall fail to
maintain any such required Office or Agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Company hereby
appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 
 The Company may also
from time to time designate one or more other Offices or Agencies where the Securities of one or more Series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no
such designation or rescission shall in any manner relieve the Company of its obligation to maintain an Office or Agency in each Place of Payment for Securities of any Series for such purposes. The Company shall give prompt written notice to the
Trustee of any such designation or rescission and of any change in the location of any such other Office or Agency. 
 Unless
otherwise provided in or pursuant to this Indenture, the Company hereby designates the City of Dallas, Texas, as a Place of Payment for each Series of Securities, initially appoints the Corporate Trust Office of the Trustee in the City of Dallas,
Texas, as the Company’s Office or Agency in the City of Dallas, Texas, for such purpose and initially appoints the Trustee as the Security Registrar for each Series of Securities and, if the Securities of any Series are convertible into or
exchangeable for Common Stock or other securities or property, initially appoints the Trustee as conversion or exchange agent, as the case may be, for the Securities of such Series. The Company may subsequently appoint a different Office or Agency
in the City of Dallas, Texas or the Borough of Manhattan, the City of New York, and, as provided in Section 305, may remove and replace from time to time the Security Registrar. 

As set forth above in this Section 1002, and unless otherwise provided pursuant to Section 301 with respect to
any Series of Securities, in the event that the Securities of a Series are originally issued solely in the form of one or more permanent global Securities and if at any time thereafter Securities of such Series are issued in definitive certificated
form in exchange for all or any portion of such global Securities (whether pursuant to Section 305 or otherwise pursuant to the terms of such Securities), the Company shall, at all times from and after the date of the first such exchange
until such time as no Securities of such Series in definitive certificated form are Outstanding, establish and maintain an Office or Agency in the City of Dallas, Texas (in addition to any other Offices or Agencies the Company is required to
maintain in respect of such Securities) where Securities of such Series may be surrendered and where notices and demands in respect of Securities of such Series and this Indenture may be served for the purposes specified in, and as contemplated by,
the first paragraph of this Section 1002. 
  

	 	Section 1003.	Money for Securities Payments to Be Held in Trust.

Securities of such Series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in Dollars sufficient to pay the principal, any premium and interest, as the case may be, so becoming due until such sums shall be paid to
such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee of its action or failure so to act. 

  
 46 

 Whenever the Company shall have one or more Paying Agents for any Series of Securities, it
shall, on or prior to each due date of the principal of, or any premium or interest on, any Securities of such Series, deposit with any Paying Agent a sum in Dollars sufficient to pay the principal, premium 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 shall cause each Paying Agent for any Series of Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall: 
 (1) hold all sums held by it for the payment of the principal of, any premium or interest on the Securities of such Series in trust for the benefit of the Persons entitled thereto until such sums shall be
paid to such Persons or otherwise disposed of as provided in or pursuant to this Indenture; 
 (2) give the Trustee notice of
any default by the Company (or any other obligor upon the Securities of such Series) in the making of any payment of principal, any premium or interest on the Securities of such Series; and 

(3) at any time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all
sums so held in trust by such Paying Agent. 
 To the extent that the terms of any Securities established pursuant to
Section 301 provide that any principal of, or premium or interest, if any, on any such Securities is or may be payable in Common Stock or other securities or property, then the provisions of this Section 1003 shall apply,
mutatis mutandis, to such Common Stock or other securities or property. 
 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 shall be released from all further liability with respect to such
sums. 
 Except as otherwise provided herein or pursuant hereto, 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, any premium or interest on any Security of any Series and remaining unclaimed for two years after such principal or such premium or interest shall have become due and payable
shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall 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, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, 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 for such Series or to be mailed
to Holders of Securities of such Series, or both, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing nor shall it be earlier than two
years after such principal and any premium or interest shall have become due and payable, any unclaimed balance of such money then remaining will be repaid to the Company. 

 

	 	Section 1004.	Corporate Existence. 

Subject to Article Eight, the Company shall do or cause to be done all things necessary to preserve and keep in full force and
effect (i) the corporate existence of the Company, (ii) the existence (corporate or other) of each Significant Subsidiary of the Company and (iii) the rights (charter and statutory), licenses and franchises of the Company and each of
its Significant Subsidiaries; provided, however, that the Company shall not be required to preserve the existence (corporate or other) of any of its Significant Subsidiaries or any such right, license or franchise of the Company or any of its
Significant Subsidiaries if the Board of Directors of the Company determines that the preservation thereof is no longer desirable in the conduct of the business of the Company and its Significant Subsidiaries taken as a whole and that the loss
thereof will not be disadvantageous in any material respect to the Holders. 

  
 47 

	 	Section 1005.	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 shall 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 1006.	Waiver of Certain Covenants. 

 The Company may omit in any particular instance to comply with any term, provision or condition set forth in Section 1002 to Section 1005, inclusive, with respect to the Securities
of any Series and, if expressly provided pursuant to Section 301(13), any additional covenants applicable to the Securities of such Series if before the time for such compliance the Holders of at least a majority in principal amount of
the Outstanding Securities of such Series, by Act of such Holders, either shall waive such compliance in such instance or generally shall have waived compliance with such term, provision or condition, but no such waiver shall extend to or affect
such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain
in full force and effect. 
  

	 	Section 1007.	Company Statement as to Compliance. 

 The Company shall deliver to the Trustee, within 180 days after the end of each fiscal year, a written statement (which need not be contained in or accompanied by an Officers’ Certificate) signed by
the principal executive officer, the principal financial officer or the principal accounting officer of the Company, stating whether or not, to the best of his or her knowledge, the Company is in default in the performance and observance of any of
the terms, provisions and conditions of this Indenture (without regard to notice requirements or periods of grace) and if the Company shall be in default, specifying all such defaults and the nature and status thereof of which he or she may have
knowledge. 
 ARTICLE ELEVEN 
 REDEMPTION OF SECURITIES 
  

	 	Section 1101.	Applicability of Article. 

Redemption of Securities of any Series at the option of the Company as permitted or required by the terms of such Securities shall be made
in accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) this Article. 
  

	 	Section 1102.	Election to Redeem; Notice to Trustee. 

 The election of the Company to redeem any Securities shall be evidenced by or pursuant to a Board Resolution. In case of any redemption at the election of the Company of less than all of the Securities of
any Series, the Company shall, at least 60 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of
such Series to be redeemed and, in the event that the Company shall determine that the Securities of any Series to be redeemed shall be selected from Securities of such Series having the same issue date, interest rate or interest rate formula,
Stated Maturity and other terms (the “Equivalent Terms”), the Company shall notify the Trustee of such Equivalent Terms. 

  
 48 

 In the case of any redemption of Securities (A) prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or (B) pursuant to an election of the Company that is subject to a condition specified in the terms of such Securities or elsewhere in this
Indenture, the Company shall furnish to the Trustee an Officers’ Certificate evidencing compliance with such restriction or condition. 
  

	 	Section 1103.	Selection by Trustee of Securities to be Redeemed. 

 If less than all of the Securities of any Series are to be redeemed or if less than all of the Securities of any Series with Equivalent Terms are to be redeemed, the particular Securities to be redeemed
shall be selected not more than 60 days prior to the Redemption Date by the Trustee from the Outstanding Securities of such Series or from the Outstanding Securities of such Series with Equivalent Terms, as the case may be, not previously called for
redemption unless otherwise required by law, by lot or such method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of portions of the principal amount of Securities of such Series; provided,
however, that no such partial redemption shall reduce the portion of the principal amount of a Security of such Series not redeemed to less than the minimum denomination for a Security of such Series established herein or pursuant hereto.

 The Trustee shall promptly notify the Company and the Security Registrar (if other than itself) in writing of the Securities
selected for redemption and, in the case of any Securities 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 Securities shall relate, in the case of any Securities redeemed or to be redeemed
only in part, to the portion of the principal of such Securities which has been or is to be redeemed. 
 Unless otherwise
specified in or pursuant to this Indenture or the Securities of any Series, if any Security selected for partial redemption is converted or exchanged for Common Stock or other securities or property in part before termination of the conversion or
exchange right with respect to the portion of the Security so selected, the converted or exchanged portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities which have been converted or
exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of such selection. 
  

	 	Section 1104.	Notice of Redemption. 

Notice of redemption shall be given in the manner provided in Section 106, not less than 30 nor more than 60 days prior to the
Redemption Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by mailing in the manner herein provided to the Holder of any Securities designated for
redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portions thereof. 

Any notice that is mailed to the Holder of any Securities in the manner herein provided shall be conclusively presumed to have been duly
given, whether or not such Holder receives the notice. 
 All notices of redemption shall state: 

(1) the Redemption Date, 
 (2) the Redemption Price, 
 (3) if less than all Outstanding Securities of any
Series are to be redeemed, the identification (and, in the case of partial redemption, the principal amount) of the particular Security or Securities to be redeemed, 
 (4) that, in case any Security is to be redeemed in part only, on and after the Redemption Date, upon surrender of such Security, the Holder of such Security will receive, without charge, a new Security
or Securities of authorized denominations for the principal amount thereof remaining unredeemed, 

  
 49 

 (5) that, on the Redemption Date, the Redemption Price shall become due and payable upon
each such Security or portion thereof to be redeemed, together (if applicable) with accrued and unpaid interest, if any, thereon (subject, if applicable, to the provisos to the first paragraph of Section 1106), and, if applicable, that
interest thereon shall cease to accrue on and after said date, 
 (6) the place or places where such Securities are to be
surrendered for payment of the Redemption Price and any accrued interest pertaining thereto, 
 (7) that the redemption is for a
sinking fund, if such is the case, 
 (8) in the case of Securities of any Series that are convertible or exchangeable into
Common Stock or other securities or property, the then current conversion or exchange price or rate, the date or dates on which the right to convert or exchange the principal of the Securities of such Series to be redeemed will commence or
terminate, as applicable, and the place or places where and the Persons to whom such Securities may be surrendered for conversion or exchange, 
 (9) the CUSIP number reference numbers of such Securities, if any (or any other numbers used by a Depositary to identify such Securities), and 

(10) if the Redemption Price or any portion thereof shall be payable, at the option of the Company or any Holders, in cash or in Common
Stock or other securities or property (or a combination thereof), a statement as to whether the Company has elected to pay the Redemption Price in cash or Common Stock or other securities or property or a combination thereof and, if applicable, the
portion of the Redemption Price that is to be paid in cash, Common Stock or other securities or property. 
 A notice of
redemption published as contemplated by Section 106 need not identify particular Securities to be redeemed. 

Notice of redemption of Securities to be redeemed at the election of the Company shall 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 shall be acceptable to the Trustee), by the Trustee in the name and at the expense of the Company. 

 

	 	Section 1105.	Deposit of Redemption Price. 

 On or prior to noon (local time in the City of Dallas, Texas) on any Redemption Date, the Company shall deposit, with respect to the Securities of any Series called for redemption pursuant to
Section 1104, 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 1003) an amount of money in Dollars sufficient to pay the
Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 301 for or in the Securities of such Series) any accrued interest on, all such Securities or
portions thereof which are to be redeemed on that date, except that, if the Securities of such Series are convertible or exchangeable into Common Stock or other securities or property, no such deposit shall be required with respect to any such
Securities (or portions thereof) which have been converted or exchanged prior to such Redemption Date. 
  

	 	Section 1106.	Securities Payable on Redemption Date. 

 Notice of redemption having been given as aforesaid, the Securities so to be redeemed (except, in the case of Securities which are convertible or exchangeable into Common Stock or other securities or
property, any such Securities which shall have been so converted or exchanged prior to the applicable Redemption Date) shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, together with (unless otherwise
provided with respect to the Securities of such Series pursuant to Section 301) accrued and unpaid interest, if any, thereon and from and after such date (unless the Company shall default in the payment of the Redemption Price and
accrued interest, if any) such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with, unless
otherwise provided in or pursuant to this Indenture, any accrued and unpaid interest thereon to but excluding the Redemption Date; provided, however, that, except as otherwise specified in or 

  
 50 

 
pursuant to this Indenture or the Securities of such Series, installments of interest on Securities whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of
such Securities, or one or more Predecessor Securities, registered as such at the close of business on the Regular Record Dates therefor according to their terms and the provisions of Section 307. 

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

 

	 	Section 1107.	Securities Redeemed in Part. 

 Any Security which is to be redeemed only in part shall be surrendered at any Office or Agency for such Security (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 shall execute and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of the same Series, 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 Security so surrendered. If a Security in global form is so surrendered, the Company shall execute, and the Trustee shall authenticate and deliver to the Depositary for such Security in global form as
shall be specified in the Company Order with respect thereto to the Trustee, without service charge, a new Security in global form in a denomination equal to and in exchange for the unredeemed portion of the principal of the Security in global form
so surrendered. 
 ARTICLE TWELVE 
 SINKING FUNDS 
  

	 	Section 1201.	Applicability of Article. 

The provisions of this Article Twelve shall be applicable to any sinking fund for the retirement of Securities of a Series
that by its terms provides for such a sinking fund, except as otherwise permitted or required in or pursuant to this Indenture or any Security of such Series issued pursuant to this Indenture. 

The minimum amount of any sinking fund payment provided for by the terms of Securities of any Series is herein referred to as a
“mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of such Series is herein referred to as an “optional sinking fund payment.” If provided for by the terms
of Securities of any Series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1202. Each sinking fund payment shall be applied to the redemption of Securities of any Series as provided for by
the terms of Securities of such Series and this Indenture. 
  

	 	Section 1202.	Satisfaction of Sinking Fund Payments with Securities. 

 The Company may, in satisfaction of all or any part of any sinking fund payment with respect to the Securities of any Series to be made pursuant to the terms of such Securities (1) deliver
Outstanding Securities of such Series (other than any of such Securities previously called for redemption or any of such Securities in respect of which cash shall have been released to the Company) and (2) apply as a credit Securities of such
Series that have been redeemed either at the election of the Company pursuant to the terms of such Series of Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities, provided that
such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the
amount of such sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities of any Series in lieu of cash payments pursuant to this Section 1202, the principal amount of Securities of such
Series to be redeemed in order to exhaust the aforesaid cash payment shall be less than $100,000, the Trustee need not call Securities of such Series for redemption, except upon Company Request, and such cash payment shall be held by the Trustee or
a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall at the request of the Company from time to time pay 

  
 51 

 
over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that Series purchased by the
Company having an unpaid principal amount equal to the cash payment requested to be released to the Company. 
  

	 	Section 1203.	Redemption of Securities for Sinking Fund. 

 Not less than 75 days prior to each sinking fund payment date for any Series of Securities, the Company shall deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing
mandatory sinking fund payment for that Series pursuant to the terms of that Series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting of
Securities of that Series pursuant to Section 1202, and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking fund payment, and will also deliver to the Trustee any Securities to be so credited and not
theretofore delivered. If such Officers’ Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund payment, the Company shall thereupon be obligated to pay the amount therein specified. Not less
than 60 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be
given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in
Section 1106 and Section 1107.

majority, in principal amount of the Outstanding Securities of a Series may be adopted at a meeting or an adjourned meeting duly reconvened and at which a quorum is present as aforesaid by the affirmative vote of the Holders of such specified
percentage in principal amount of the Outstanding Securities of such Series. 
 Any resolution passed or decision taken at any
meeting of Holders of Securities of any Series duly held in accordance with this Section shall be binding on all the Holders of Securities of such Series, whether or not such Holders were present or represented at the meeting. 

 

	 	Section 1405.	Determination of Voting Rights; Conduct and Adjournment of Meetings. 

 (1) Notwithstanding any other provisions of this Indenture, the Trustee may make such reasonable regulations as it may deem advisable for any meeting of Holders of Securities of such Series in regard to
proof of the holding of Securities of such Series and of the appointment of proxies and in regard to the appointment and duties of inspectors of votes, the submission and examination of proxies, certificates and other evidence of the right to vote,
and such other matters concerning the conduct of the meeting as it shall deem appropriate. Except as otherwise permitted or required by any such regulations, the holding of Securities shall be proved in the manner specified in
Section 104 and the appointment of any proxy shall be proved in the manner specified in Section 104. Such regulations may provide that written instruments appointing proxies, regular on their face, may be presumed valid and
genuine without the proof specified in Section 104 or other proof. 

  
 53 

 (2) The Trustee shall, by an instrument in writing, appoint a temporary chairman of the
meeting, unless the meeting shall have been called by the Company or by Holders of Securities as provided in Section 1402(2), in which case the Company or the Holders of Securities of the Series calling the meeting, as the case may be,
shall in like manner appoint a temporary chairman. A permanent chairman and a permanent secretary of the meeting shall be elected by vote of the Persons entitled to vote a majority in principal amount of the Outstanding Securities of such Series
represented at the meeting. 
 (3) At any meeting, each Holder of a Security of such Series or proxy shall be entitled to one
vote for each $1,000 principal amount of Securities of such Series held or represented by him; provided, however, that no vote shall be cast or counted at any meeting in respect of any Security challenged as not Outstanding and ruled by the chairman
of the meeting to be not Outstanding. If the Securities of such Series are issuable in minimum denominations of less than $1,000, then a Holder of such a Security in a principal amount of less than $1,000 shall be entitled to a fraction of one vote
that is equal to the fraction that the principal amount of such Security bears to $1,000. The chairman of the meeting shall have no right to vote, except as a Holder of a Security of such Series or proxy. 

(4) Any meeting of Holders of Securities of any Series duly called pursuant to Section 1402 at which a quorum is present may
be adjourned from time to time by Persons entitled to vote a majority in principal amount of the Outstanding Securities of such Series represented at the meeting; and the meeting may be held as so adjourned without further notice.

 The vote upon any resolution submitted to any meeting of Holders of Securities of any Series shall be by written ballots on which shall be subscribed the signatures of the Holders of Securities of such
Series or of their representatives by proxy and the principal amounts and serial numbers of the Outstanding Securities of such Series held or represented by them. The permanent chairman of the meeting shall appoint two inspectors of votes who shall
count all votes cast at the meeting for or against any resolution and who shall make and file with the secretary of the meeting their verified written reports in triplicate of all votes cast at the meeting. A record, at least in triplicate, of the
proceedings of each meeting of Holders of Securities of any Series shall be prepared by the secretary of the meeting and there shall be attached to said record the original reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more persons having knowledge of the facts setting forth a copy of the notice of the meeting and showing that said notice was given as provided in Section 1402 and, if applicable, Section 1404. Each copy
shall be signed and verified by the affidavits of the permanent chairman and secretary of the meeting and one such copy shall be delivered to the Company, and another to the Trustee to be preserved by the Trustee, the latter to have attached thereto
the ballots voted at the meeting. Any record so signed and verified shall be conclusive evidence of the matters therein stated.

ARTICLE I 

ACQUISITION OF HCBI BY IBG 
 Section 1.01. Merger of HCBI with and into Newco. Subject to the terms and conditions of this Agreement and the Agreement and Plan of Merger to be entered into between HCBI and Newco, and
joined in by IBG (the “Merger Agreement”), in the form attached hereto as Exhibit “A”, Newco will merge with and into HCBI pursuant to the provisions of Chapter 10 of the Texas Business Organizations Code (the
“TBOC”). 
 Section 1.02. Effects of the Merger. HCBI shall continue as the corporation resulting
from the Merger (the “Resulting Corporation”), and the Merger shall otherwise have the effects set forth in Section 10.008 of the TBOC and as set forth in the Merger Agreement. 

Section 1.03. Certificate of Formation and Bylaws. The Certificate of Formation and Bylaws of the Resulting Corporation shall
be as set forth in the Merger Agreement. 
 Section 1.04. Directors and Officers. The directors and officers of the
Resulting Corporation shall be as set forth in the Merger Agreement. 
 Section 1.05. Merger Consideration. At the
Effective Time (as defined in Section 1.09) by virtue of this Agreement and without any further action on the part of any holder, all of the HCBI Shares outstanding at the Effective Time shall, subject to adjustment pursuant to
Section 8.07, be converted into the right to receive the consideration set forth in this Section 1.05 as follows. 

A. Any HCBI Shares that are owned by HCBI (other than as a fiduciary) shall automatically be canceled and retired and all rights with
respect thereto shall cease to exist, and no consideration shall be delivered in exchange therefor. 
 B. Subject to
Section 1.05(C), each HCBI Share issued and outstanding immediately before the Effective Time (excluding HCBI Shares cancelled pursuant to Section 1.05(A)) shall be converted into, and shall be canceled in exchange for, the right to
receive each of the following: 
 (1) A cash amount equal to $30.44 (the “Per Share Cash
Consideration”) subject to adjustment pursuant to Section 8.07; 

  
 2 

 (2) A number of shares of IBG Stock equal to the quotient of
(i) $56.52, divided by (ii) the Average Closing Price (the “Per Share Stock Consideration”). The “Average Closing Price” shall be the average, determined to one-one hundredth of one cent, of the
volume weighted sale price per IBG Share on The NASDAQ Stock Market, Inc. Global Select Market System (“NASDAQ”) for ten (10) consecutive trading days ending on and including the third trading day preceding the Closing Date, as
reported by Bloomberg; 
 (3) If the Average Closing Price is less than 90% of the Average Announcement Price,
IBG may in its sole discretion elect to: (a) increase the Per Share Cash Consideration to an amount up to $43.48 (the “Increased Per Share Cash Consideration”), subject to adjustment pursuant to Section 8.07; and (b) reduce
the Per Share Stock Consideration to a number of shares of IBG Stock equal to the quotient of (x) the difference between $86.96 and the Increased Per Share Cash Consideration; divided by (y) the Average Closing Price. The “Average
Announcement Price” is $47.1770; and 
 (4) Notwithstanding anything in this Agreement to the contrary,
IBG will not issue any certificates or scrip representing fractional IBG Shares otherwise issuable pursuant to the Merger. In lieu of the issuance of any such fractional shares, IBG shall pay to each former holder of HCBI Shares otherwise entitled
to receive such fractional share an amount of cash determined by multiplying (i) the Average Closing Price by (ii) the fraction of an IBG Share which such holder would otherwise be entitled to receive pursuant to this Section 1.05.

 For purposes of illustration only, calculation of the Per Share Stock Consideration pursuant to subsection (B)(2) above based
on different hypothetical Average Closing Prices is set forth in Confidential Schedule 1.05.  
 C. Subject only to
dissenter’s rights under Subchapter H of Chapter 10 of the TBOC, all HCBI Shares shall no longer be outstanding and shall be cancelled and retired and all rights with respect thereto shall cease to exist, and each holder of HCBI Shares shall
cease to have any rights with respect thereto, except the right to receive the consideration provided for in this Section 1.05. 
 D. If the Tangible Book Value (as defined in Section 8.07) on the fifth business day preceding the Closing Date (as defined in Section 2.01) (the “Calculation Date”) is greater than
$24,000,000, then on the day prior to the Closing Date, HCBI may distribute to its shareholders an amount equal to the difference between (i) the actual amount of Tangible Book Value as of the Calculation Date, less
(ii) $24,000,000. Any such distribution is referred to as the “Section 1.05(D) Distribution.” 

Section 1.06. Treatment of Newco Shares. Each Newco Share (as defined in Section 4.05) issued and outstanding
immediately before the Effective Time shall, on and after the Effective Time, be converted into a like number of shares of the Resulting Corporation with the effect that the aggregate number of common shares of the Resulting Corporation outstanding
after the Effective Time shall be equal to the aggregate number of Newco Shares outstanding 

  
 3 

 
immediately before the Effective Time, all of which shall continue to be owned by IBG. The authorized number of common shares of the Resulting Corporation shall be the same as the authorized
number of Newco Shares immediately before the Effective Time. 
 Section 1.07. Dissenting Shareholders.
Notwithstanding anything in this Agreement to the contrary, HCBI Shares that are held by shareholders of HCBI who have complied with the terms and provisions of Subchapter H of Chapter 10 of the TBOC (each a “Dissenting
Shareholder”) shall be entitled to those rights and remedies set forth in Subchapter H of Chapter 10 of the TBOC; but if that a shareholder of HCBI fails to perfect, withdraws or otherwise loses any such right or remedy granted by the
Subchapter H of Chapter 10 of the TBOC, each HCBI Share held by such shareholder shall be converted into and represent only the right to receive the consideration as specified in Section 1.05. 

Section 1.08. SEC Filing and Shareholder Approval. 
 A. IBG shall prepare a registration statement on Form S-4 or other applicable form (the “Registration Statement”) to be filed by IBG with the Securities and Exchange Commission
(“SEC”) in connection with the issuance of the IBG Shares to the HCBI Shareholders pursuant to Section 1.05 (including the Proxy Statement for the Meeting (as defined below) and prospectus and other proxy solicitation materials
of HCBI constituting a part thereof (together, the “Proxy Statement”) and all related documents). HCBI shall prepare and furnish to IBG such information relating to HCBI and its directors, officers and shareholders as may be
reasonably required to comply with SEC rules and regulations in connection with the Registration Statement. IBG shall provide HCBI, and its legal, financial and accounting advisors, the right to review and provide comments upon (i) the
Registration Statement in advance of such Registration Statement being filed with the SEC and (ii) on all amendments and supplements to the Registration Statement and all responses to requests for additional information and replies to comments
relating to the Registration Statement before filing or submission to the SEC. IBG shall consider in good faith all comments from HCBI and its legal, financial and accounting advisors to the Registration Statement, all amendments and supplements
thereto and all responses to requests for additional information. HCBI agrees to cooperate with IBG and IBG’s counsel and accountants in requesting and obtaining appropriate opinions, consents and letters from its financial advisor and
independent auditor and in taking such other actions in connection with the Registration Statement and the Proxy Statement. If HCBI has cooperated and promptly provided all information reasonably requested as described above, IBG shall file, or
cause to be filed, the Registration Statement with the SEC on or before July 15, 2014. IBG shall use its commercially reasonable efforts to cause the Registration Statement to be declared effective under the Securities Act as promptly as
reasonably practicable after the filing thereof. IBG also agrees to use its commercially reasonable efforts to obtain all necessary state securities law or “Blue Sky” permits and approvals required to carry out the transactions
contemplated by this Agreement. 
 B. The HCBI Board shall duly call, give notice of, and cause to be held, a meeting of its
shareholders (the “Meeting”) and will direct that this Agreement and the transactions contemplated hereby be submitted to a vote at the Meeting. Specifically, the HCBI Board will present for the consideration of HCBI shareholders a
proposal to approve and adopt this Agreement, the Merger, the Merger Agreement and the transactions contemplated hereby 

  
 4 

 
and thereby. The HCBI Board will (i) cause proper notice of the Meeting to be given to the HCBI shareholders in compliance with applicable law and regulations, (ii) distribute to the
HCBI shareholders the Proxy Statement, (iii) recommend by the affirmative vote of the HCBI Board a vote in favor of approval of the proposals set forth in this Section 1.08(B), subject to Section 1.08(C), and (iv) perform such
other acts as may reasonably be requested by IBG to ensure that shareholder approval of the proposals set forth in this Section 1.08(B) are obtained. HCBI shall print and commence the mailing (at its expense) of the Proxy Statement to its
shareholders on or before the third business day after the date that the Registration Statement is declared effective and a final prospectus (relating to the Registration Statement) and Proxy Statement is on file with the SEC before such mailing.

 C. Notwithstanding the foregoing, HCBI and the Board of Directors of HCBI (the “HCBI Board”) are permitted
to change its recommendation as contemplated by Section 1.08(B)(iii) (“Change in Recommendation”) if and only to the extent that: 
 (1) HCBI, HCB and the HCBI Representatives (as defined in Section 5.11), have complied in all material respects with Section 5.11; 

(2) the HCBI Board, after consultation with its outside counsel, has determined in good faith that failure to make a
Change in Recommendation would reasonably be expected to result in a violation of its fiduciary duties under applicable law; and 
 (3) if the HCBI Board intends to make a Change in Recommendation after HCBI has received an Acquisition Proposal, (a) the HCBI Board has concluded in good faith, after giving effect to all of the
adjustments which may be offered by IBG pursuant to subclause (c) below, that such Acquisition Proposal constitutes a Superior Proposal, (b) HCBI shall notify IBG, at least five business days in advance, of its intention to make a Change
in Recommendation in response to such Superior Proposal (including the identity of the party making such Acquisition Proposal) and furnish to IBG a written description of the material terms of the Superior Proposal and copies of such other material
documents that HCBI is not required to keep confidential, and (c) before making such a Change in Recommendation, HCBI shall, and shall cause its financial and legal advisors to, during the period after HCBI’s delivery of the notice
referred to in subclause (b) above, negotiate with IBG in good faith for a period of up to five business days (to the extent IBG desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such
Acquisition Proposal ceases to constitute a Superior Proposal. 
 Section 1.09. Exchange Procedures. 

A. On the business day before the Closing Date, IBG shall deposit or cause to be deposited in trust with Wells Fargo Bank, N.A. (the
“Exchange Agent”) (i) an authorization to issue shares in book entry form representing the aggregate number of IBG Shares which the holders of HCBI Shares are entitled to receive pursuant to Section 1.05, and (ii) an
amount of cash equal to the aggregate amount of cash which the holders of HCBI Shares are entitled to receive pursuant to Section 1.05 (collectively, the “Aggregate Merger Consideration”). 

  
 5 

 B. As soon as practicable after the Effective Time, with the intent to be within ten
business days after the Effective Time, IBG shall cause the Exchange Agent to mail to each record holder of an outstanding certificate or certificates representing HCBI Shares (the “Certificates”), a form letter of transmittal which
will specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon proper delivery of the Certificates to the Exchange Agent and contain instructions for use in effecting the surrender of the
Certificates for payment therefor. The form and substance of the letter of transmittal and any associated cover letter shall be mutually acceptable to IBG and HCBI before such transmittal materials are mailed to the holders of the Certificates. Upon
surrender to the Exchange Agent of a Certificate, together with such letter of transmittal properly completed and duly executed (the “Transmittal Materials”), the holder of such Certificate shall be entitled to receive in exchange
therefor (i) an amount of cash equal to the product of (x) the Per Share Cash Consideration, or the Adjusted Per Share Cash Consideration (as defined in Section 8.07), if applicable, multiplied by (y) the number of HCBI Shares
represented by the Certificate (the “Surrendered Shares”), (ii) a number of IBG Shares equal to the product of (x) the Per Share Stock Consideration, multiplied by (y) the number of Surrendered Shares, and
(iii) an amount of cash as payment in lieu of the issuance of fractional IBG Shares calculated in accordance with Section 1.05(B)(3), and such Certificate shall forthwith be canceled. The consideration to be received by a shareholder of
HCBI upon surrender of his Certificate is referred to as the “Merger Consideration.” Until surrendered in accordance with this Section 1.09, each Certificate (other than Certificates representing Dissenting Shares) shall
represent for all purposes the right to receive the Merger Consideration without any interest thereon. Promptly after receipt of the Transmittal Materials, IBG will cause the Exchange Agent to review the Transmittal Materials in order to verify
proper completion and execution thereof. As soon as practicable after the Effective Time and the surrender of a Certificate to the Exchange Agent, together with properly completed and executed Transmittal Materials, with the intent to be no later
than five business days after such surrender, IBG will cause the Exchange Agent to promptly deliver the Merger Consideration. 

C. After the Effective Time, the share transfer ledger of HCBI shall be closed and there shall be no transfers on the share transfer
books of HCBI of the HCBI Shares which were outstanding immediately before such time of filing. If, after the Effective Time, Certificates are presented to IBG, they shall be promptly presented to the Exchange Agent and exchanged as provided in this
Section 1.09. 
 D. Former shareholders of HCBI shall be entitled to vote after the Effective Time at any meeting of
IBG’s shareholders the number of IBG Shares into which their shares are converted, regardless of whether such shareholders of HCBI have surrendered their Certificates in exchange therefor. 

E. No dividends or other distributions declared after the Effective Time with respect to IBG Shares and payable to the holders thereof
shall be paid to the holder of a Certificate until such holder surrenders such Certificate to the Exchange Agent in accordance with this Section 1.09. After the surrender of a Certificate in accordance with this Section 1.09, the holder
thereof shall be entitled to receive any such dividends or other distributions, without interest thereon, which had become payable after the Effective Time with respect to the IBG Shares represented by such Certificate. 

  
 6 

 F. Any portion of the Aggregate Merger Consideration (including the proceeds of any
investments thereof) that remains unclaimed by the shareholders of HCBI for six months after the Exchange Agent mails the letter of transmittal pursuant to this Section 1.09 shall be delivered to IBG upon demand, and any shareholders of HCBI
who have not theretofore complied with the exchange procedures in this Section 1.09 shall look to IBG only, and not the Exchange Agent, for the payment of the Merger Consideration in respect of such shares. If outstanding Certificates for HCBI
Shares are not surrendered or the payment for them is not claimed before the date on which such IBG Shares or cash would otherwise escheat to any governmental unit or agency, the unclaimed items shall, to the extent permitted by abandoned property
or any other applicable law, become the property of IBG (and to the extent not in its possession shall be delivered to it), free and clear of all claims or interest of any person previously entitled to such property. 

G. If any IBG Shares are to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered,
it shall be a condition of the issuance thereof that the Certificate so surrendered shall be appropriately endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form (reasonably satisfactory to IBG) for transfer,
and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other taxes required by reason of the issuance of a certificate representing IBG Shares in any name other than that of the registered holder of
the Certificate surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or not payable. 
 H. None of IBG, HCBI, the Exchange Agent or any other person shall be liable to any former holder of HCBI Shares for any IBG Share (or dividends or distributions with respect thereto) or cash properly
delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. 
 I. If any Certificate has
been lost, stolen or destroyed, then upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by IBG or the Exchange Agent, the posting by such person of a bond in such
amount as IBG or the Exchange Agent may direct (not to exceed the amount of Merger Consideration relating to the relevant missing Certificate) as indemnity against any claim that may be made against IBG, Independent Bank, or HCBI with respect to
such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Merger Consideration deliverable in respect thereof pursuant to this Agreement. 

Section 1.10. Effective Time. The “Effective Time” means the effective time of the Merger as specified in the
Certificate of Merger filed with and certified by the Texas Secretary of State (“TSOS”). The Certificate of Merger shall be filed with the TSOS on the Closing Date. 

Section 1.11. Subsequent Merger and Bank Merger. Immediately after the Effective Time, IBG shall cause the Subsequent Merger
and the Bank Merger to be consummated. 
 Section 1.12. Anti-Dilution Provisions. If, between the date of this
Agreement and the Effective Time, the IBG Shares are changed into a different number or class of shares by reason of any reclassification, recapitalization, split-up, combination, exchange of shares or

  
 7 

 
readjustment, or a share dividend thereon is declared with a record date within said period, the Per Share Stock Consideration shall be adjusted accordingly; but an offering or sale of IBG Shares
shall not be deemed a reclassification, recapitalization, split-up, combination, exchange of shares or readjustment of the IBG Shares. 
 Section 1.13. Tax Matters. 
 A. None of IBG, Independent Bank, Newco,
HCBI or HCB has taken or agreed to take any action, or is aware of any fact or circumstance, that would prevent the Merger and the Subsequent Merger, together, from qualifying as a reorganization within the meaning of § 368 of the Code. IBG,
Independent Bank, Newco, HCBI and HCB shall each use its reasonable best efforts to cause (i) the Merger and the Subsequent Merger, together, to qualify as a “reorganization” within the meaning of § 368(a) of the Code, and
(ii) each of IBG and HCBI to be a party to the reorganization within the meaning of § 368(b) of the Code. Each of IBG, Independent Bank, Newco, HCBI and HCB agrees to file all of its tax returns, including complying with the filing
requirements of Treasury Regulations § 1.368-3, consistent with the treatment of the Merger as a “reorganization” within the meaning of § 368(a) of the Code and in particular as a transaction described in § 368(a)(1)(A) of
the Code, Treasury Regulations § 1.368-2(b)(1)(ii) and Revenue Ruling 2001-46, 2001-42 I.R.B. 321, Situation 1. This Agreement is intended to constitute a “plan of reorganization” within the meaning of Treasury Regulations §
1.368-2(g). 
 B. None of IBG, Independent Bank, Newco, HCBI or HCB has taken or agreed to take any action, or is aware of any
fact or circumstance, that would prevent the Bank Merger from qualifying as a reorganization within the meaning of § 368 of the Code. IBG, Independent Bank, Newco, HCBI and HCB shall each use its reasonable best efforts to cause (i) the
Bank Merger to qualify as a “reorganization” within the meaning of § 368(a) of the Code, and (ii) each of Independent Bank and HCB to be a party to the reorganization within the meaning of § 368(b) of the Code. Each of IBG,
Independent Bank, Newco, HCBI and HCB agrees to file all of its tax returns, including complying with the filing requirements of Treasury Regulations § 1.368-3, consistent with the treatment of the Bank Merger as a “reorganization”
within the meaning of § 368(a) of the Code and in particular as a transaction described in § 368(a)(1)(A) of the Code and Treasury Regulations § 1.368-2(b)(1)(ii). This Agreement is intended to constitute a “plan of
reorganization” within the meaning of Treasury Regulations § 1.368-2(g). 
 C. IBG and Newco shall deliver to Andrews
Kurth LLP and Harris Law Firm PC a “Tax Representation Letter,” dated as of the effective date of the Registration Statement and signed by an officer of IBG, containing representations of IBG and Newco, and HCBI shall deliver to Andrews
Kurth LLP and Harris Law Firm PC a “Tax Representation Letter,” dated as of the effective date of the Registration Statement and signed by an officer of HCBI, containing representations of HCBI, in each case as shall be reasonably
necessary or appropriate to enable Andrews Kurth LLP to render its tax opinion in connection with the Registration Statement and to enable Harris Law Firm PC to render its tax opinion in connection with the Registration Statement. IBG and Newco

LLP a “Tax Representation Letter,” dated as of the Closing Date and signed by an officer of Independent Bank, containing representations of Independent Bank, and HCB shall deliver to Andrews Kurth LLP a “Tax Representation
Letter,” dated as of the Closing Date and signed by an officer of HCB, containing representations of HCB, in each case as shall be reasonably necessary or appropriate to enable Andrews Kurth LLP to render the tax opinions described in
Section 8.15. Each of IBG, Independent Bank, Newco, HCBI and HCB shall use its reasonable best efforts not to take or cause to be taken any action that would cause to be untrue (or fail to take or cause not to be taken any action that would
cause to be untrue) any of the certifications and representations included in the tax representation letters described in this Section 1.13(C). 
 D. A HCBI representative shall prepare or cause to be prepared and file or cause to be filed, subject to the review and reasonable approval of IBG, all Tax Returns for each of HCBI and HCB for all periods
ending on or prior to the Closing Date that are required to be filed after the Closing Date. If required by applicable law, IBG shall, and shall cause HCBI or HCB to, authorize and direct their respective officers to execute any and all Tax Returns
required to be filed by each of HCBI and HCB pursuant to this Section 1.13(D). The shareholders of HCBI and HCB shall be responsible for the amount of Taxes of HCBI and HCB shown due on such Tax Returns. All such Tax Returns shall be prepared
in a manner that is consistent with the past custom and practice of HCBI and HCB effective for fiscal year 2013, except as required by a change in applicable law.

term of any such agreement or (B) that are related or of a similar nature and that in the aggregate obligate or would reasonably be expected to obligate HCBI or HCB for an amount in excess of $50,000 over the entire term of such related

each case free and clear of any lessee-granted security interests, claims, liens (including tax liens), forfeitures, mortgages, pledges, penalties, encumbrances, assignments or charges whatsoever except as established by the lease or applicable law.

limitation applicable to any tax return for any period. 
 C. Proper and accurate amounts, if required, have been withheld by
HCBI and HCB from their respective employees, independent contractors, creditors, shareholders or other third parties for all periods in material compliance with the tax withholding provisions of applicable law.

have not been audited or examined and no such audit is currently pending or, to the Best Knowledge of HCBI, threatened. 

  
 20 

 E. Neither HCBI nor HCB has entered into any tax sharing agreement, tax allocation
agreement, tax indemnity agreement, or similar contract or arrangement or any current or potential contractual obligation to indemnify any other person with respect to taxes that will require any payment by HCBI or HCB after the date of this
Agreement.

income, excise, gross receipts, gross income, ad valorem, profits, gains, property, capital, sales, transfer, use, value-added, stamp, documentation, payroll, employment, severance, withholding, duties, intangibles, franchise, backup withholding,
and other taxes, charges, levies or like assessments together with all penalties and additions to tax and interest thereon, provided that in the case of HCBI and HCB, the terms “tax” and “taxes” shall not include federal
income tax, due to the status of HCBI and HCB as an S corporation and a qualified Subchapter S subsidiary, respectively. Additionally, the terms “tax return” and “tax returns” means any return, declaration, report,
claim for refund or information return or statement relating to taxes, including any schedule or attachment thereto and including any amendment thereof. 
 G. HCBI has delivered or made available to IBG correct and complete copies of all federal income tax returns filed by HCBI with the Internal Revenue Service (“IRS”), examination reports,
and statements of deficiencies assessed against or agreed to by HCBI and HCB, if any, since with respect to any taxable period beginning on or after December 31, 2009. 
 H. Confidential Schedule 3.14 sets forth an accurate and complete description as to the United States federal net operating and capital loss carryforwards for HCBI and HCB (including the year such
net operating or capital loss was generated and any limitations of such net operating or capital loss carryforwards under Code § § 382, 383 or 384 or the Treasury Regulations, excluding any such limitations arising from the
transactions contemplated under this Agreement) as of December 31, 2012. 
 I. Effective as of January 1, 1997 (the
“S Election Date”), HCBI made a valid election to be taxed, for federal income tax purposes, as a Subchapter S corporation and that election is in effect as of the date of this Agreement. Effective on the S Election Date, HCBI made
a valid election for HCB to be taxed, for federal income tax purposes, as a qualified Subchapter S subsidiary (a “QSSS”), and each such election is in effect as of the date of this Agreement. Neither HCBI nor HCB have taken any
action that would cause HCBI to cease being an S corporation or cause HCB to cease being a QSSS before the Closing Date. HCBI and HCB are not currently and will not at any time before the Closing Date be liable for any tax under Code
§1374. 
 J. Except as set forth in Confidential Schedule 3.14, for any tax year of HCBI beginning on or after the S
Election Date, no audit by the IRS has commenced or been completed pursuant to Code §§6241 through 6245 regarding Subchapter S items, and no agreement, consent or waiver to extend the statute of limitations of Subchapter S items of HCBI
has been given. To HCBI’s Best Knowledge, for any tax year of HCBI beginning after the S Election Date, each HCBI shareholder’s treatment of Subchapter S items with respect to HCBI is consistent with the manner in which HCBI has filed its
tax returns, and no audit by the IRS of any HCBI shareholder has occurred except as set forth in Confidential Schedule 3.14. 

  
 21 

 K. Since the S Election Date, HCBI has not been required to include in income any material
adjustment pursuant to Code §481 by reason of a voluntary change in accounting method initiated by HCBI, and the IRS has not initiated or proposed any such material adjustment or change in accounting method (including any method for determining
reserves for bad debts maintained by HCBI). No dividend or other distribution declared or paid by HCBI since the S Election Date has exceeded the portion of HCBI’s “accumulated adjustments account” (within the meaning of Treasury
Regulation § 1.1368-2) properly allocated to such distribution in accordance with that regulation, and no dividend or distribution declared or paid by HCBI before the Effective Time will exceed the portion of HCBI’s accumulated adjustments
account properly allocated to such distribution in accordance with that regulation. 
 Section 3.15. Insurance.
Confidential Schedule 3.15 contains a complete list and brief description of all policies of insurance, including fidelity and bond insurance, maintained as of the date of this Agreement by HCBI and HCB. All such policies (A) are
sufficient for compliance by HCBI and HCB, in all material respects, with all requirements of applicable law and all agreements to which HCBI and HCB are parties, (B) are valid, outstanding and enforceable, except as enforceability may be
limited by bankruptcy, conservatorship, insolvency, moratorium, reorganization, receivership, or similar laws and judicial decisions affecting the rights of creditors generally and by general principles of equity (whether applied in a proceeding at
law or equity), and (C) are presently in full force and effect, and, except as set forth in Confidential Schedule 3.15, no written notice has been received of the cancellation, or threatened or proposed cancellation, of any such policy
and there are no unpaid premiums due thereon. Neither HCBI nor HCB is in default with respect to the material provisions of any such policy or has failed to give any notice or present any known claim thereunder in a due and timely fashion. Each
material Property of HCBI and HCB is insured for the benefit of HCBI and HCB in amounts deemed adequate by HCBI’s and HCB’s respective management against risks customarily insured against. Except as set forth in Confidential Schedule
3.15, there have been no claims under any fidelity bonds of HCBI and HCB since March 31, 2012 and to the Best Knowledge of HCBI, there are no facts that would reasonably be expected to form the basis of a claim under such bonds. 

Section 3.16. No Material Adverse Change. Except as disclosed in the representations and warranties made in this ARTICLE III
and the Confidential Schedules hereto, there has not been any Material Adverse Change with respect to HCBI or HCB since March 31, 2014, nor to the Best Knowledge of HCBI, has any event occurred that has resulted in, or has a reasonable
probability of resulting in the future in, a Material Adverse Change with respect to HCBI or HCB.

(other than compensation for current services not yet due and payable and reimbursement of expenses arising in the ordinary course of business) of HCBI or HCB, and none of such persons owes any amount to HCBI or HCB. There are no agreements,
instruments, commitments, extensions of credit, tax sharing or allocation agreements or other contractual agreements of any kind between or among HCBI, whether on its own behalf or in its capacity as trustee or custodian for the funds of any

limited by applicable bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and the availability of injunctive relief, specific performance and other equitable remedies), and are not subject to any
asserted or, to the Best Knowledge of HCBI, threatened, defenses, offsets or counterclaims that may reasonably be asserted against HCBI, HCB or the present holder thereof. The credit and collateral files of HCB contain all material information
(excluding general, local or national industry, economic or similar conditions) actually known to HCBI or HCB that is required to evaluate, in accordance with generally prevailing practices in the banking industry, the collectability of the loan
portfolio of HCB (including loans that will be outstanding if HCB advances funds it is obligated to advance), except for items identified on HCB’s internal exception list which has been made available to IBG. All loans classified substandard,
doubtful, loss, nonperforming or problem loans internally by management of HCB or any applicable Regulatory Agency (as defined in Section 11.10) are set forth on HCB’s watch list, which is set forth in Confidential Schedule 3.19.
Notwithstanding anything to the contrary contained in this Section, no representation or warranty is being made as to the sufficiency of collateral securing, or the collectability of, the loans of HCB.

laws relating to its relationships with its employees, and HCBI believes that the relationship between HCB and its employees is good. To the Best Knowledge of HCBI, no key executive officer or manager of any of the operations of HCB or any group of

Section 3.21. Condition of Assets. All tangible assets used by HCBI and HCB are in good operating condition, ordinary wear
and tear excepted, and conform, in all material respects, with all applicable ordinances, regulations, zoning and other laws, whether federal, state or local. None of HCB’s premises or equipment is in need of maintenance or repairs other than

Environmental Laws (as defined in Section 11.10). HCBI has not received any written notice of any past, present, or future conditions, events, activities, practices or incidents that would reasonably be expected to materially interfere with or

 Section 3.24. Absence of Certain Business Practices. Neither HCBI nor HCB nor
any of their respective officers, employees or agents, nor any other person acting on their behalf, has, directly or indirectly, since March 31, 2012, given or agreed to give any gift or similar benefit to any customer, supplier, governmental
employee or other person who is or may be in a position to help or hinder the business of HCBI or HCB (or assist HCBI or HCB in connection with any actual or proposed transaction) that (A) may reasonably be expected to subject HCBI or HCB to
any damage or penalty in any civil, criminal or governmental litigation or proceeding, (B) if not given in the past, may reasonably have resulted in a Material Adverse Change or (C) if not continued in the future may reasonably be expected

 Section 3.25. Books and Records. The minute books, stock certificate books and stock transfer ledgers of HCBI and HCB have been kept accurately in the ordinary course of business and are
complete and correct in all material respects. The transactions entered therein represent bona fide transactions, and there have been no material transactions involving the business of HCBI and HCB that properly should have been set forth therein
and that have not been accurately so set forth. 
 Section 3.26. Forms of Instruments, Etc. HCBI has made and will
make available to IBG copies of all of HCB’s standard forms of notes, mortgages, deeds of trust and other routine documents of a like nature used on a regular and recurring basis in the ordinary course of its business. 

Section 3.27. Fiduciary Responsibilities. Each of HCBI and HCB has performed in all material respects all of its duties as a
trustee, custodian, guardian or as an escrow agent in a manner that complies in all material respects with all applicable laws, regulations, orders, agreements, instruments and common law standards, where the failure to so perform would result in a
Material Adverse Change. 
 Section 3.28. Guaranties. Except in the ordinary course of business, according to past
business practices and in material compliance with applicable law, HCBI or HCB have not guaranteed the obligations or liabilities of any other person, firm or corporation. 
 Section 3.29. Employee Benefit Plans. 
 A. Set forth on
Confidential Schedule 3.29 is a complete and correct list of all “employee benefit plans” (as defined in Section 3(3) of ERISA), all specified fringe benefit plans as defined in Code § 6039D, and all other bonus,
incentive, compensation, retention, deferred compensation, profit sharing, stock option, stock appreciation right, stock bonus, stock purchase, employee stock ownership, savings, severance, supplemental unemployment, layoff, salary continuation,
retirement, pension, health, life insurance, disability, group insurance, vacation, holiday, sick leave, fringe benefit or welfare plan, or any other similar plan, agreement, policy or understanding (whether written or oral, qualified or
nonqualified, currently effective or 

  
 25 

 
terminated), and any trust, escrow or other agreement related thereto, which (a) is currently maintained or contributed to by HCBI or HCB, or with respect to which HCBI or HCB has any
liability, and (b) provides benefits to any officer, employee, service provider, former officer or former employee of HCBI or HCB, or the dependents of any thereof, regardless of whether funded or unfunded (herein collectively the
“Employee Plans” and each individually an “Employee Plan”). 
 B. No Employee Plan is a
defined benefit plan within the meaning of Section 3(35) of ERISA. HCBI has delivered or made available to IBG true, accurate and complete copies of the documents comprising each Employee Plan and any related trust agreements, annuity
contracts, insurance policies or any other funding instruments (“Funding Arrangements”), any contracts with independent contractors (including actuaries and investment managers) that relate to any Employee Plan, the Form 5500 filed
with the IRS in each of the three (3) most recent plan years with respect to each Employee Plan, and related schedules and opinions, and such other documents, records or other materials related thereto, as reasonably requested by IBG. There
have been no prohibited transactions (described under ERISA § 406 or Code § 4975(c)), breaches of fiduciary duty or any other breaches or violations of any law applicable to the Employee Plans and related Funding Arrangements
that would reasonably be expected to subject IBG, Independent Bank, HCBI or HCB to any material taxes, penalties or other liabilities. Each Employee Plan that is represented to be qualified under Code § 401(a) has a current favorable
determination or opinion letter, and does not have any amendments for which the remedial amendment period under Code § 401(b) has expired. All reports, descriptions and filings required by the Code, ERISA or any government agency with
respect to each Employee Plan have been timely and completely filed or distributed. Each Employee Plan has been operated in material compliance with applicable law or in accordance with its terms. There are no pending claims, lawsuits or actions
relating to any Employee Plan (other than ordinary course claims for benefits) and, to the Best Knowledge of HCBI, none are threatened. No written or, to the Best Knowledge of HCBI, oral representations have been made by HCBI or HCB to any employee
or former employee of HCBI or HCB promising or guaranteeing any employer payment or funding for the continuation of medical, dental, life or disability coverage for such person, their dependent, or any beneficiary for any period of time beyond the
end of the current plan year or beyond termination of employment (except to the extent of coverage required under Code § 4980B or applicable state law). Compliance with FAS 106 will not create any material change to the HCBI Financial
Statements or the HCB Call Reports. Except to the extent that the payment would constitute an “excess parachute payment” under Code § 280G, there are no contracts or arrangements providing for payments that will be nondeductible
or subject to excise tax under Code § § 4999 or 280G, nor will IBG or Independent Bank be required to “gross up” or otherwise compensate any person because of the limits contained in such Code sections. There are no
surrender charges, penalties, or other costs or fees that would reasonably be expected to be imposed by any person against HCBI, HCB, an Employee Plan, or any other person, including an Employee Plan participant or beneficiary, as a result of the
consummation of the transactions contemplated by this Agreement with respect to any insurance, annuity or investment contracts or other similar investment held by any Employee Plan. 

  
 26 

 C. With respect to each “employee benefit plan” (as defined in ERISA) maintained
or contributed to or required to be contributed to, currently or in the past, by any trade or business with which HCBI or HCB is required by any of the rules contained in the Code or ERISA to be treated as a single employer (“Controlled
Group Plans”): 
 (i) All Controlled Group Plans which are “group health plans” (as defined
in the Code and ERISA) have been operated before the Closing such that failures to operate such group health plans in compliance, in all material respects, with Part 6 of Subtitle B of Title 1 of ERISA and Code § § 4980B and 4980D
would not reasonably be expected to subject HCBI or HCB to liability; 
 (ii) There is no Controlled Group Plan
that is a defined benefit plan (as defined in Section 3(35) of ERISA), nor has there been a Controlled Group Plan that is a defined benefit plan in the last five (5) calendar years; and 

(iii) There is no Controlled Group Plan that is a “multiple employer plan” or “multi-employer plan”
(as either such term is defined in ERISA), nor has there been a Controlled Group Plan that is either a multiple employer plan or multi-employer plan since 2007. 
 D. All Employee Plan documents, annual reports or returns, audited or unaudited financial statements, actuarial valuations, summary annual reports, and summary plan descriptions issued with respect to the
Employee Plans are correct, complete, and current in all material respects, have been timely filed, and there have been no material changes in the information set forth therein. 

E. All contributions (including all employer contributions, employee salary reduction contributions and all premiums or other payments
(other than claims)) that are due have been made with respect to each Employee Plan. 
 Section 3.30. No Excess
Parachute Payments. No amount, whether in cash or property or vesting of property, that will be received by or benefit provided to, any officer, director or employee of HCBI, HCB or any of their respective Affiliates who is a “disqualified
individual” (as such term is defined in Treasury Regulation § 1.280G-1) under any employment, severance or termination agreement, other compensation arrangement or benefit plan currently in effect will be an “excess parachute
payment” (as such term is defined in Code § 280G(b)(1)) solely as a result of the transactions contemplated by this Agreement; and no such person is entitled to receive any additional payment from HCBI, HCB, or IBG if that the excise
tax of Code § 4999(a) is imposed on such person. 
 Section 3.31. Bank Secrecy Act, Foreign Corrupt Practices Act
and U.S.A. Patriot Act. HCB is in material compliance with the Bank Secrecy Act (12 U.S.C. §§ 1730(d) and 1829(b)), the United States Foreign Corrupt Practices Act and the International Money Laundering Abatement and Anti-Terrorist
Financing Act, otherwise known as the U.S.A. Patriot Act, and all regulations promulgated thereunder. HCB has properly certified all foreign deposit accounts and has made all necessary tax withholdings on all of its deposit accounts; furthermore,
HCB has timely and properly filed and maintained all requisite Currency Transaction Reports and other related forms, including any requisite Custom Reports required by any agency of the United States Treasury Department, including the IRS. HCB has
timely filed all Suspicious Activity 

  
 27 

 
Reports with the Financial Institutions – Financial Crimes Enforcement Network (U.S. Department of the Treasury) required to be filed by it pursuant to the laws and regulations referenced in
this Section. 
 Section 3.32. Data Processing Agreements. HCB obtains its data processing services, ATM, and other
information technology services exclusively through the contracts or agreements with the persons or entities described on Confidential Schedule 3.32 (“DP Contracts”). A true and correct executed copy of each DP Contract, as
in effect as of the date hereof, has been provided to IBG. Other than the DP Contracts, HCBI has no agreement with any other person or entity for data processing, ATM or other technology services.

HCBI has not received any written notices of any violation of such acts or any of the regulations promulgated thereunder, and it has not received any written notice of any, and to the Best Knowledge of HCB there is no, threatened administrative
inquiry, proceeding or investigation with respect to its compliance with such laws.

Section 3.36. Zoning and Related Laws. All real property owned or operated by HCB and the use thereof is in compliance with
all applicable laws, ordinances, regulations, orders or requirements, including building, zoning and other laws, except where the failure, whether individually or in the aggregate, to be so in compliance would not reasonably be expected to cause a
Material Adverse Change.

or records of HCBI or HCB in connection with any Acquisition Proposal, other than as provided herein or as compelled by law; or (iii) cooperate with any third party to make any Acquisition Proposal, other than the sale by HCB of assets in the

 41 

 
Representatives may engage in negotiations and discussions with, and furnish any information and other access (so long as all such information and access has previously been made available to IBG
or is made available to IBG before or concurrently with the time such information or access is made available to such person) to, any person making such Acquisition Proposal if, and only if, the HCBI Board determines in good faith, after
consultation with outside legal and financial advisors, that (i) such Acquisition Proposal is or is reasonably capable of becoming a Superior Proposal and (ii) the failure of the HCBI Board to furnish such information or access or enter
into such discussions or negotiations would reasonably be expected to be a violation of its fiduciary duties to the HCBI shareholders; but before furnishing any material nonpublic information, HCBI shall have received from the person making such
Acquisition Proposal an executed confidentiality agreement with terms at least as restrictive in all material respects on such person as the Confidentiality Agreement entered into with IBG on August 7, 2013, which confidentiality agreement
shall not prohibit HCBI from complying with the terms of this Section 5.11. HCBI will promptly, and in any event within two business days, (x) notify IBG in writing of the receipt of such Acquisition Proposal or any request for nonpublic
information relating to HCBI or for access to the properties, books or records of HCBI by any person that has made, or to the Best Knowledge of HCBI may be considering making, an Acquisition Proposal and (y) communicate the material terms of
such Acquisition Proposal to IBG, including as they may change upon any modification or amendment to the terms thereof. HCBI will keep IBG reasonably apprised of the status of and other matters relating to any such Acquisition Proposal on a timely
basis. 
 C. Nothing contained in this Section 5.11 shall prevent HCBI or the HCBI Board from (i) taking the actions
provided in Sections 1.08(C) or 5.11(B), (ii) responding to an unsolicited bona fide Acquisition Proposal for the sole purpose of clarifying the terms and conditions of the Acquisition Proposal, (iii) informing any person who submits an
unsolicited bona fide Acquisition Proposal of HCBI’s obligations pursuant to Section 5.11(A) or (iv) in consultation with outside counsel, complying with its disclosure obligations under federal or state law in connection with a
Change in Recommendation.

Section 5.13. Environmental Investigation; Right to Terminate Agreement. 

A. IBG and its consultants, agents and representatives, at the sole cost and expense of IBG, shall have the right to the same extent that
HCBI has the right, but not the obligation or responsibility, to inspect any Property, including conducting asbestos surveys and sampling, environmental assessments and investigation, and other environmental surveys and analyses including soil and
ground sampling (“Environmental Inspections”). IBG shall notify HCBI in writing before any Environmental Inspection, and HCBI may place reasonable restrictions on the time of such Environmental Inspection. If, as a result of any
such Environmental Inspection, further investigation (“Secondary Investigation”) including, test borings, soil, water and other sampling is deemed desirable by IBG, IBG shall (i) notify HCBI in

  
 42 

 
writing of any Property for which it intends to conduct such a Secondary Investigation and the reasons for the Secondary Investigation, and (ii) at the sole cost and expense of IBG, commence
the Secondary Investigation. IBG shall give reasonable written notice to HCBI of the Secondary Investigation, and HCBI may place reasonable time and place restrictions on the Secondary Investigation. 

B. IBG shall make available to HCBI the results and reports of such Environmental Inspections and Secondary Investigations promptly after
IBG receives or is advised of such results. IBG shall not have any liability or responsibility of any nature whatsoever for the results, conclusions or other findings related to any Environmental Inspection, Secondary Investigation or other
environmental survey. If this Agreement is terminated, except as otherwise required by law, reports to any Governmental Authority of the results of any Environmental Inspection, Secondary Investigation or other environmental survey shall not be made
by IBG. IBG shall make no such report before Closing unless required to do so by applicable law, and in such case will give HCBI reasonable written notice of IBG’s intentions. 

C. IBG shall have the right to terminate this Agreement if (i) the factual substance of any warranty or representation set forth in
Section 3.22 is not materially true and accurate; (ii) the results of such Environmental Inspection, Secondary Investigation or other environmental survey are disapproved by IBG because the Environmental Inspection, Secondary Investigation
or other environmental survey identifies material violations or potential material violations of Environmental Laws; (iii) HCBI has refused to allow IBG to conduct an Environmental Inspection or Secondary Investigation in a manner that IBG
reasonably considers necessary; (iv) the Environmental Inspection, Secondary Investigation or other environmental survey identifies any past or present event, condition or circumstance that would or potentially could reasonably be expected to
require a material remedial or cleanup action or result in a Material Adverse Change; (v) the Environmental Inspection, Secondary Investigation or other environmental survey identifies the presence of any underground or above ground storage
tank in, on or under any Property that is not shown to be in material compliance with all Environmental Laws applicable to the tank either at the date of this Agreement or at a future time certain, or that has had a release of petroleum or some
other Hazardous Material that has not been cleaned up to the satisfaction of the relevant Governmental Authority or any other party with a legal right to compel cleanup; or (vi) the Environmental Inspection, Secondary Investigation or other
environmental survey identifies the presence of any asbestos-containing material in, on or under any Property, the removal of which could reasonably be expected to result in a Material Adverse Change. IBG shall advise HCBI in writing (the
“Environmental Notice”) as to whether IBG intends to terminate this Agreement because IBG disapproves of the results of the Environmental Inspection, Secondary Inspection or other environmental survey. Upon receipt of the
Environmental Notice, HCBI shall have the opportunity to correct any objected to violations or conditions to IBG’s reasonable satisfaction within 30 days after the date of the Environmental Notice. If that HCBI fails to demonstrate its
satisfactory correction of the violations or conditions to IBG, IBG may terminate the Agreement on the 31st day after the date of the Environmental Notice. 
 D. HCBI agrees to make available to IBG and its consultants, agents and representatives all documents and other material relating to environmental conditions of any Property including the results of other
environmental inspections and surveys. HCBI also agrees 

  
 43 

 
that all engineers and consultants who prepared or furnished such reports may discuss such reports and information with IBG and shall be entitled to certify the same in favor of IBG and its
consultants, agents and representatives and make all other data available to IBG and its consultants, agents and representatives.

preserves the rights of the participants in such Employee Plans (including vesting rights). HCBI and HCB shall terminate the retention agreements listed in Confidential Schedule 5.14 and the agreement listed in Confidential Schedule

and HCB to execute and deliver contemporaneously with the execution of this Agreement, the Voting Agreement, in the form attached hereto as Exhibit “B”, and HCBI acknowledges that, upon the execution and delivery of the Voting
Agreement, such persons shall have agreed that they will vote the HCBI Shares owned by them in favor of this Agreement and the transactions contemplated hereby, including the Merger, subject to required regulatory approvals.

writing by IBG, consistent with GAAP, immediately before Closing, make such accounting entries as HCBI may reasonably request in order to conform the accounting records of HCBI to the accounting policies and practices of IBG. No such adjustment by
HCBI or HCB shall of itself constitute or be deemed to be a breach, violation or failure by HCBI or HCB to satisfy any representation, warranty, covenant, condition or other provision or constitute grounds for termination of this Agreement by IBG or
be an acknowledgment by HCBI of any adverse circumstances for purposes of determining whether the conditions to IBG’s obligations under this Agreement have been satisfied, nor will any such adjustment affect the calculation of the Tangible Book
Value under Section 8.07. 
 Section 5.22. D & O Liability Insurance. Contemporaneously with the Closing,
HCBI and HCB shall purchase an extended reporting period for three years under HCBI’s existing directors and officers liability insurance policy, on terms approved by IBG, for purposes of covering actions occurring before the Effective Time.

IBG that the HCBI Board determines in its good faith judgment to be more favorable to HCBI’s shareholders than the Merger (taking into account, in good faith, the written opinion, with only customary qualifications, of HCBI’s independent
financial advisor that the value of the consideration to HCBI’s shareholders provided for in such Acquisition Proposal exceeds the value of the consideration to HCBI’s shareholders provided for in the Merger) and for which financing, to
the extent required, is then committed or which, in the good faith judgment of the HCBI Board (taking into account, in good faith, the written advice of HCBI’s independent financial advisor), is reasonably capable of being obtained by such
third person.

to insist on strict compliance with an obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent or other failure. No party to this Agreement shall by any act (except by a written
instrument given pursuant to Section 11.17) be deemed to have waived any right or remedy hereunder or to have acquiesced in any breach of any of the terms and conditions hereof. No failure to exercise, nor any delay in exercising any right,
power or privilege hereunder by any party hereto shall operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder shall preclude any other or further exercise thereof or the exercise of any other right,
power or privilege. A waiver of any party of any right or remedy on any one occasion shall not be construed as a bar to any right or remedy that such party would otherwise have on any future occasion or to any right or remedy that any other party
may have hereunder. 
 Section 11.17. Amendments. This Agreement may be amended by the parties hereto, by action
taken or authorized by their respective boards of directors, at any time before or after approval of this Agreement by the HCBI shareholders; but after the approval of this Agreement by the HCBI shareholders, there shall not be, without the further
approval of the HCBI shareholders, any amendment of this Agreement that decreases the consideration to be paid for the HCBI Shares pursuant to Section 1.05 that materially and adversely affects the rights of the HCBI shareholders hereunder.

duly organized and existing under the laws of the State of Texas with authorized capital consisting of 1,000 common shares, par value $1.00 per share (“Newco Shares”), of which 1,000 shares are issued and outstanding as of the date
of this Merger Agreement; 
 WHEREAS, the majority of the respective board of directors of HCBI and Newco, pursuant to the
authority given by and in accordance with the provisions of the Texas Business Organizations Code, as amended (the “TBOC”), has approved this Merger Agreement and the Merger and has authorized the execution hereof; and 

WHEREAS, as and when required by the provisions of this Merger Agreement, all such action as may be necessary or appropriate shall be

 AGREEMENT: 

NOW, THEREFORE, Newco and HCBI, joined by IBG, hereby agree that Newco shall be merged with and into HCBI on the following terms and
conditions: 
 1. Merger of Newco and HCBI. At the Effective Time (as defined in Section 16), Newco shall be merged
with and into HCBI pursuant to the provisions of Chapter 10 of the TBOC. 

  
 A-1

 2. Effects of the Merger. The Merger shall have the effects set forth in
Section 10.008 of the TBOC. After the Merger, HCBI shall continue as the corporation resulting from the Merger (the “Resulting Corporation”), and the separate corporate existence of Newco shall cease. The name of the Resulting
Corporation shall be “Houston City Bancshares, Inc.” The existing offices and facilities of HCBI immediately preceding the Merger shall be the principal offices and facilities of the Resulting Corporation after the Merger. At the Effective
Time, all rights, title and interests to all real estate and other property owned by each of Newco and HCBI shall be allocated to and vested in the Resulting Corporation without reversion or impairment, without further act or deed, and without any
transfer or assignment having occurred, but subject to any existing liens or encumbrances thereon. At the Effective Time, all liabilities and obligations of Newco and HCBI shall be allocated to the Resulting Corporation, and the Resulting
Corporation shall be the primary obligor therefor, and no other party to the Merger shall be liable therefor. At the Effective Time, a proceeding pending by or against either Newco or HCBI may be continued as if the Merger did not occur, or the
Resulting Corporation may be substituted in the proceedings. 
 3. Certificate of Formation and Bylaws. As a result of
the Merger, the Articles of Incorporation and Bylaws of HCBI shall continue in effect as the Articles of Incorporation and Bylaws of the Resulting Corporation until the same shall be amended and changed as provided by applicable law.

Resulting Corporation and shall hold office from the Effective Time until their respective successors are duly elected or appointed and qualified in the manner provided in the Articles of Incorporation and Bylaws of the Resulting Corporation or as
otherwise provided by applicable law. 
 5. Conversion of HCBI Shares. At the Effective Time, each HCBI Share issued and
outstanding immediately before the Effective Time, shall, by virtue of the Merger, and without any action on the part of any holder thereof, be converted into the right to receive the consideration set forth in Section 1.05 of the
Reorganization Agreement. At the Effective Time, each HCBI Share that is owned by HCBI (other than as a fiduciary) shall automatically be canceled and retired and all rights with respect thereto shall cease to exist, and no consideration shall be
delivered in exchange therefor. 
 6. Conversion of Newco Shares. The Newco Shares outstanding at the Effective Time
shall, at the Effective Time and by virtue of the Merger, be converted into a like number of common shares of the Resulting Corporation with a par value of $1.00 per share, with the effect that the number of common shares of the Resulting
Corporation outstanding immediately after the Effective Time shall be equal to the aggregate number of Newco Shares outstanding immediately before the Effective Time, all of which shall continue to be owned by IBG. The authorized number of common
shares of the Resulting Corporation shall be the same as the authorized number of Newco Shares immediately before the Effective Time. 
 7. Rights of Former HCBI Shareholders. Until surrendered for exchange in accordance with the Reorganization Agreement, each certificate and document theretofore

  
 A-2

 
representing HCBI Shares shall, from and after the Effective Time, represent for all purposes only the right to receive the applicable consideration therefor set forth in Section 1.05 of the
Reorganization Agreement. No interest will be paid on such consideration. 
 8. Share Transfer Books. The share transfer
books of HCBI shall be closed as of the close of business at the Effective Time, and no transfer of record of any of the HCBI Shares shall take place thereafter. 
 9. Shareholder Approval. This Merger Agreement and the Merger shall be submitted to the shareholders of HCBI at a meeting called to be held as promptly as practicable and to the sole shareholder of
Newco by written consent of thereof. Upon approval by the requisite votes of the shareholders of HCBI and the approval of the sole shareholder of Newco, this Merger Agreement shall be made effective as soon as practicable thereafter in the manner
provided in the Reorganization Agreement. 
 10. Dissenters’ Rights. Any shareholder of HCBI who objects to the
Merger and follows the procedure for dissent as set forth in Subchapter H of Chapter 10 of the TBOC shall be entitled to the rights and benefits afforded to dissenting shareholders by such statute.

or the termination thereof on the part of either HCBI, IBG or the directors, officers, employees, agents or shareholders of either of them shall be determined pursuant to the terms and provisions of the Reorganization Agreement. Such terms and
provisions are hereby incorporated herein by reference for all purposes.

without the requisite approval of such shareholders. Any waiver, modification or amendment of this Merger Agreement shall be in writing.

obligations of HCB to the Director. Effective as of the effective time of the acquisition of HCBI and HCB by IBG pursuant to the Agreement, the Director for himself and on behalf of his heirs and assigns (the “Director Releasing

construed as an admission of liability, all liability being expressly denied by HCBI and HCB. The Director hereby represents and warrants that the consideration hereby acknowledged for entering into this Release and the transactions contemplated
hereby is greater than the value of all claims, demands, actions and causes of action herein relinquished, released, renounced, abandoned, acquitted, waived and/or discharged, and that this Release is in full settlement, satisfaction and discharge
of any and all such claims, demands, actions, and causes of action that the Director may have or be entitled to against HCBI and HCB and its predecessors, assigns, legal representatives, officers, directors, employees, attorneys and agents other

provision shall be deemed severable, the remainder of this Release and the application of all other provisions shall not be affected thereby and shall be enforced to the greatest extent permitted by law. This Release is executed as of the date first
above written. As used herein, the singular includes the plural, the masculine includes the feminine and neuter, and vice versa.

 EXHIBIT D 
 DIRECTOR 
 SUPPORT AGREEMENT 

THIS SUPPORT AGREEMENT (the “Support Agreement”) is made and entered into as of the      day of
            , 2014, by and between Independent Bank Group, a Texas corporation (“IBG”) and
                     (the “Director”). 
 RECITALS: 
 WHEREAS, IBG and Houston Community Bancshares, Inc.
(“HCBI”), have entered into that certain Agreement and Plan of Reorganization, dated as of June 2, 2014 (the “Reorganization Agreement”), which provides for the acquisition of Houston Community Bank, N.A., a
wholly owned subsidiary of HCBI (“HCB”), by IBG through the merger of HCB with and into Independent Bank, IBG’s wholly owned subsidiary. Terms with their initial letter capitalized and not otherwise defined herein shall have
the meanings given them in the Reorganization Agreement; 
 WHEREAS, the Director is a director of HCBI and HCB; 

WHEREAS, in connection with consummation of the transactions contemplated by the Reorganization Agreement, IBG and the Director have
agreed to enter into this Support Agreement. 
 AGREEMENT: 

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein and intending to be legally bound hereby, IBG and
the Director agree as follows: 
 1. Support. The Director agrees to use reasonable efforts to refrain from harming
HCB’s goodwill and their customer and client relationships. 
 2. Covenants. For and in consideration of
consummation of the transactions contemplated by the Reorganization Agreement, the Director agrees that for a period of two years after the Closing Date (as defined in the Reorganization Agreement) (the “Support Period”), the Director will
not, without the prior written consent of IBG, directly or indirectly, (i) solicit banking business of any current customers of HCB; (ii) acquire more than 2% of, charter, operate or own control of, any financial services company or
institution that provides banking services similar to those provided by HCB; (iii) serve as an officer, director, employee, agent or consultant to any financial services company or institution that provides banking services similar to those
provided by HCB, or (iv) establish or operate a branch or other office of a financial services company or institution that provides banking services similar to those provided by HCB, in each case set forth in clauses (ii), (iii) and (iv),
that has its main office, a branch office, or other office in Houston-Sugar Land-Baytown Metropolitan Statistical Area. 

  
 D-1

 Notwithstanding the provisions of this Section 2, the Director shall not be prohibited
from (i) serving as an officer, director, employee, agent or consultant of the financial services company or institution set forth on Confidential Schedule 1 attached hereto (an “Excepted Company”), or
(ii) establishing or operating a branch or other office of an Excepted Company; but the Director shall be subject to the prohibitions in Section 2(a)(i) even in his role with an Excepted Company. 

The Director agrees that (i) this Support Agreement is entered into in connection with the sale to IBG of the goodwill of the
business of HCBI and HCB, (ii) is ancillary to the Agreement and Plan of Reorganization, (iii) the Director is receiving valuable consideration in the Reorganization Agreement for this Support Agreement, and (iv) the limitations as to
time, geographical area, and scope of activity to be restrained by this Support Agreement are reasonable and acceptable, and do not impose any greater restraint than is reasonably necessary to protect the goodwill and other business interests that
IBG is acquiring from HCBI and HCB. 
 This Support Agreement creates a narrowly tailored advance approval requirement in order
to avoid unfair competition and irreparable harm to IBG and Independent Bank, the successor to HCB, and is not intended or to be construed as a general restraint from engaging in a lawful profession or a general covenant against competition. Nothing
herein will prohibit (i) ownership of less than 2% of the publicly traded capital stock of a corporation so long as this is not a controlling interest, or (ii) ownership of mutual fund investments. The Director may not avoid the purpose
and intent of this paragraph by engaging in conduct within the geographically limited area from a remote location through means such as telecommunications, written correspondence, computer generated or assisted communications, or other similar
methods. The Director agrees that if, at some later date, a court of competent jurisdiction determines that the non-solicitation agreement set forth in this Support Agreement does not meet the criteria set forth by applicable law, this Support
Agreement may be reformed by the court and enforced to the maximum extent permitted under applicable law. 
 3.
Confidentiality, Non-Solicitation of Employees. The Director agrees that he is familiar with HCB’s confidential business information and trade secrets, including without limitation, customer lists and information, account lists,
and other business plans and information, and salary, pay scale, capabilities, experiences, skill and desires of HCB’s employees (the “Confidential Information”). The Confidential Information does not include any
information that (i) is generally available to and known by the public, (ii) was available on a non-confidential basis from a source other than HCB, or (iii) was independently acquired or developed without violating any laws or
obligations under this Support Agreement. The Director agrees to maintain the confidentiality of the Confidential Information and not use such Confidential Information for any purpose. The Director further covenants and agrees that, during the
Support Period, he shall not recruit, directly or indirectly, any employees of Independent Bank, as the successor to HCB, nor shall he contact or communicate with any employees of Independent Bank for the purpose of inducing employees to terminate
their employment with Independent Bank. Notwithstanding the foregoing, the Director shall not be prohibited from hiring any employee who (i) is terminated by Independent Bank or who has voluntarily resigned from employment without direct or
indirect solicitation by the Director, (ii) responds to any general advertisement appearing in a newspaper, magazine or trade publication, or (iii) is a referral made by a placement agency or service so long as such placement agency or
service has not been instructed by Director to solicit from Independent Bank such employee. 

  
 D-2

 4. Maintenance of Banking Relationship. During the Support Period, Director shall
(i) maintain his borrowing and deposit relationships currently existing (in amounts consistent with amounts currently existing) with HCB at the date of this Support Agreement with Independent Bank as the successor to HCB, and (ii) refrain
from establishing any new borrowing or deposit relationship with any other person or entity. 
 5. Termination. This
Support Agreement shall terminate after the end of the period set forth in Section 2 above. 
 6. Effective Time.
This Support Agreement shall become effective on the Closing Date (as defined in the Reorganization Agreement). If the Reorganization Agreement is terminated in accordance with its terms, this Support Agreement shall not become effective and shall
be of no further force and effect. 
 7. Injunctive Relief. If that IBG and/or the Director violate any of the provisions
set forth in this Support Agreement, IBG and the Director acknowledge that IBG and Independent Bank would suffer immediate and irreparable harm and would not have an adequate remedy at law for money damages if that any of the covenants contained
herein were not performed in accordance with their terms or otherwise were materially breached. Accordingly, IBG and the Director agree that, without the necessity of proving actual damages or posting bond or other security, IBG and Independent Bank
shall be entitled to temporary or permanent injunction or injunctions to prevent breaches of such performance and to specific enforcement of such covenants in addition to any other remedy to which IBG and Independent Bank may be entitled, at law or
in equity. In such a situation, the parties agree that IBG and Independent Bank may pursue any remedy available, including declaratory relief, concurrently or consecutively in any order as to any breach, violation, or threatened breach or violation
of this Support Agreement, and the pursuit of any particular remedy or remedies shall not be deemed an election of remedies or waiver of the right to pursue any other remedy. 
 8. Assignability. Neither this Support Agreement nor any of the rights, interests or obligations under this Support Agreement may be assigned, in whole or in part, by operation of law or otherwise
by any of the parties hereto without the prior written consent of the other party. Any assignment in violation of the preceding sentence shall be void. Subject to the preceding two sentences, this Support Agreement will be binding upon, inure to the
