GUARANTY BANCSHARES, INC.

3.625% FIXED-TO-FLOATING RATE Subordinated NoteS due APRIL 1, 2032

Subordinated Notes. This Subordinated Note is one of a series of notes of Guaranty Bancshares, Inc., a Texas corporation (the “Company”) designated as the “3.625% Fixed-to-Floating Rate Subordinated Notes due April 1, 2032” (the “Subordinated Notes”) issued pursuant to that Subordinated Note Purchase Agreement, dated as of the date upon which this Subordinated Note was originally issued (the “Issue Date”) by and between the Company and each of the purchasers of the Subordinated Notes identified in the signature page thereto (the “Purchase Agreement”).

Payment. The Company, for value received, promises to pay to [●], or its registered assigns, the principal sum of Thirty-Five Million Dollars (U.S.) ($35,000,000) plus accrued but unpaid interest on April 1, 2032 (the “Maturity Date”) and to pay interest thereon (i) from and including the Issue Date to but excluding April 1, 2027 or the earlier redemption date contemplated by Section 4 (Redemption) of this Subordinated Note, (the “Fixed Rate Period”), at the rate of 3.625% per annum, computed on the basis of a 360-day year consisting of twelve 30-day months and payable semi-annually in arrears on April 1 and October 1 of each year (each payment date, a “Fixed Interest Payment Date”), beginning on October 1, 2022, and (ii) from and including April 1, 2027 to but excluding the Maturity Date or the earlier redemption date contemplated by Section 4 (Redemption) of this Subordinated Note, (the “Floating Rate Period”), at the rate per annum, reset quarterly, equal to the Floating Interest Rate (as defined below) determined on the Floating Interest Determination Date (as defined below) of the applicable interest period plus 192 basis points, computed on the basis of a 360-day year and the actual number of days elapsed and payable quarterly in arrears (each quarterly period, a “Floating Interest Period”) on January 1, April 1, July 1, and October 1 of each year, beginning on July 1, 2027. The term “Floating Interest Determination Date” means the date upon which the Floating Interest Rate is determined by the Calculation Agent (as defined herein) pursuant to the Three-Month Term SOFR Conventions (as defined herein). Any payment of principal of or interest on this Subordinated Note that would otherwise become due and payable on a day which is not a Business Day shall become due and payable on the next succeeding Business Day, with the same force and effect as if made on the date for payment of such principal or interest, and no interest will accrue in respect of such payment for the period after such day; provided, that in the event that any scheduled Floating Interest Payment Date falls on a day that is not a Business Day and the next succeeding Business Day falls in the next succeeding calendar month, such Floating Interest Payment Date will be accelerated to the immediately preceding Business Day, and, in each such case, the amounts payable on such Business Day will include interest accrued to, but excluding, such Business Day. Dollar amounts resulting from interest calculations will be rounded to the nearest cent, with one half cent being rounded upward. Notwithstanding anything to the contrary provided in this Subordinated Note or the Purchase Agreement, (i) in the event the Three-Month Term SOFR (as defined herein) is less than zero, the Three-Month Term SOFR shall be deemed to be zero, and (ii) if a Benchmark Transition Event (as defined herein) and its related Benchmark Replacement Date (as defined herein) have occurred and the Benchmark Replacement (as defined herein) is less than zero, then the Benchmark Replacement shall be deemed to be zero.

A-4

The Company shall take such actions as are necessary to ensure that from the commencement of the Floating Rate Period for so long as any of the Subordinated Notes remain outstanding there will at all times be a Calculation Agent appointed to calculate Three-Month Term SOFR in respect of each Floating Rate Period. The calculation of Three-Month Term SOFR for each applicable Floating Rate Period by the Calculation Agent will (in the absence of manifest error) be final and binding. The Calculation Agent’s determination of any interest rate and its calculation of interest payments for any period will be maintained on file at the Calculation Agent’s principal offices, and will be made available to any Noteholder (as defined herein) upon request. The Calculation Agent may be removed by the Company at any time. If the Calculation Agent is unable or unwilling to act as Calculation Agent or is removed by the Company, the Company will promptly appoint a replacement Calculation Agent. The Calculation Agent may not resign its duties without a successor having been duly appointed; provided, that if a successor Calculation Agent has not been appointed by the Company and such successor accepted such position within thirty (30) calendar days after the giving of notice of resignation by the Calculation Agent, then the resigning Calculation Agent may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Calculation Agent with respect to such series. For the avoidance of doubt, if at any time there is no Calculation Agent appointed by the Company, then the Company shall be the Calculation Agent.

An “Interest Payment Date” is either a Fixed Rate Interest Payment Date or a Floating Rate Interest Payment Date, as applicable.

A “Floating Interest Period” means:

the period from, and including, each Floating Interest Payment Date to, but excluding, the next succeeding Floating Interest Payment Date, except for the initial Floating Interest Period, which will be the period from, and including, July 1, 2027 to, but excluding, the next succeeding Floating Interest Payment Date.

The “Floating Interest Rate” means:

initially Three-Month Term SOFR (as defined below).

Notwithstanding the foregoing clause (i) of this Section 2(d):

If the Calculation Agent determines prior to the relevant Floating Interest Determination Date that a Benchmark Transition Event and its related Benchmark Replacement Date (each of such terms as defined below) have occurred with respect to Three-Month Term SOFR, then the Company shall promptly provide notice of such determination to the Noteholders and Section 2(e) (Effect of Benchmark Transition Event) will thereafter apply to all determinations, calculations and quotations made or obtained for the purposes of calculating the Floating Interest Rate payable on the Subordinated Notes during a relevant Floating Interest Period.

However, if the Calculation Agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR, but for any reason the Benchmark Replacement has not been determined as of the relevant Floating Interest Determination Date, the Floating Interest Rate for the applicable Floating Interest

A-5

Period will be equal to the Floating Interest Rate on the last Floating Interest Determination Date for the Subordinated Notes, as determined by the Calculation Agent (as defined below).

Effect of Benchmark Transition Event.

If the Calculation Agent determines that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time (as defined below) in respect of any determination of the Benchmark (as defined below) on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Subordinated Notes during the relevant Floating Interest Period in respect of such determination on such date and all determinations on all subsequent dates.

In connection with the implementation of a Benchmark Replacement, the Calculation Agent will have the right to make Benchmark Replacement Conforming Changes from time to time, and such changes shall become effective without consent from the relevant Noteholders (as defined below) or any other party.

The Calculation Agent is expressly authorized to make certain determinations, decisions and elections under the Subordinated Notes, including with respect to the use of Three-Month Term SOFR as the Benchmark under this Section 2(e). Any determination, decision or election that may be made by the Calculation Agent under the terms of the Subordinated Note, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date, and any decision to take or refrain from taking any action or any selection:

will be conclusive and binding absent manifest error;

if made by the Company as the Calculation Agent, will be made in the Company’s sole discretion;

if made by the Calculation Agent other than the Company, will be made after consultation with the Company, and the Calculation Agent will not make any such determination, decision or election to which the Company reasonably objects; and

notwithstanding anything to the contrary in this Subordinated Note or the Purchase Agreement, shall become effective without consent from the relevant Noteholders (as defined below) or any other party.

If the Calculation Agent fails to make any determination, decision or election that it is required to make under the terms of the Subordinated Notes, then the Company will make such determination, decision or election on the same basis as described above.

For the avoidance of doubt, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, interest payable on this Subordinated Note for the Floating Rate Period will be an annual rate equal to the sum of the applicable Benchmark Replacement and the spread specified on the face hereof.

A-6

If the then-current Benchmark is Three-Month Term SOFR, the Calculation Agent will have the right to establish the Three-Month Term SOFR Conventions, and if any of the foregoing provisions concerning the calculation of the interest rate and the payment of interest during the Floating Rate Period are inconsistent with any of the Three-Month Term SOFR Conventions determined by the Calculation Agent, then the relevant Three-Month Term SOFR Conventions will apply.

As used in this Subordinated Note:

“Affiliate(s)” means, with respect to any Person, such Person’s immediate family members, partners, members or parent and Subsidiary corporations, and any other Person directly or indirectly controlling, controlled by, or under common control with said Person and their respective Affiliates.

“Benchmark” means, initially, Three-Month Term SOFR; provided that if the Calculation Agent determines on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Three-Month Term SOFR or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

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

the sum of (i) Compounded SOFR and (ii) the Benchmark Replacement Adjustment;

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

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

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

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

A-7

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

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

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

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

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

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

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

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

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

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark

A-8

Replacement Date will be deemed to have occurred prior to the Reference Time for purposes of such determination.

In the event of any liquidation of the Company, holders of Senior Indebtedness of the Company shall be entitled to be paid in full with such interest as may be provided by law before any payment shall be made on account of principal of or interest on this Subordinated Note. Additionally, in the event of any insolvency, dissolution, assignment for the benefit of creditors or any liquidation or winding up of or relating to the Company, whether voluntary or involuntary, holders of Senior Indebtedness shall be entitled to be paid in full before any payment shall be made on account of the

A-12

principal of or interest on the Subordinated Notes, including this Subordinate Note. In the event of any such proceeding, after payment in full of all sums owing with respect to the Senior Indebtedness, the Noteholders, together with the holders of any obligations of the Company ranking on a parity with the Subordinated Notes, shall be entitled to be paid from the remaining assets of the Company the unpaid principal thereof, and the unpaid interest thereon before any payment or other distribution, whether in cash, property or otherwise, shall be made (i) with respect to any obligation that by its terms expressly is junior to in the right of payment to the Subordinated Notes or (ii) on account of any capital stock.

The provisions of this paragraph shall not apply to any payment with respect to which Section 3(b) above would be applicable.

Nothing herein shall act to prohibit, limit or impede the Company from issuing additional debt of the Company having the same rank as the Subordinated Notes or which may be junior or senior in rank to the Subordinated Notes.

Each Noteholder, by its acceptance hereof, further acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration for each holder of any Senior Indebtedness, whether such Senior Indebtedness was created or acquired before or after the issuance of the Subordinated Notes, to acquire and continue to hold, or to continue to hold, such Senior Indebtedness, and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold or in continuing to hold such Senior Indebtedness.

Upon the occurrence of a Tier 2 Capital Event, a Tax Event or an Investment Company Event, the Company may redeem this Subordinated Note, subject to Section 4(f) (Regulatory Approvals) hereof, in whole, but not in part, at any time, upon giving not less than ten (10) calendar days’ notice to the Noteholders at an amount equal to 100% of the outstanding principal amount being redeemed plus accrued and unpaid interest, to but excluding the redemption date. “Tier 2 Capital Event” means the receipt by the Company of an opinion of counsel to the effect that, as a result of (a) any amendment to, or change (including any announced prospective change) in, the laws or any regulations thereunder of the United States or any rules, guidelines or policies of an applicable regulatory authority for the Company or (b) any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which amendment or change is effective or which pronouncement or decision is announced on or after the date of original issuance of the Subordinated Notes, the Subordinated Notes do not constitute, or within 90 days of the date of such opinion will not constitute, Tier 2 capital (or its equivalent if the Company were subject to such capital requirement) for purposes of capital adequacy guidelines of the Federal Reserve (or any successor

A-13

regulatory authority with jurisdiction over bank holding companies), as then in effect and applicable to the Company that would preclude the Subordinated Notes from being included as Tier 2 capital. “Tax Event” means the receipt by the Company of an opinion of counsel to the effect that, as a result of (a) an amendment to, or change (including any announced prospective change) in, the laws or any regulations of the United States or any political subdivision or taxing authority, or (b) any official administrative pronouncement or judicial decision interpreting or applying such laws or regulations, which change or amendment becomes effective or which pronouncement or decision is announced on or after the date of the issuance of the Notes, there is more than an insubstantial risk that the interest payable on the Subordinate Note is not, or within 120 calendar days after the receipt of such opinion will not be, deductible by the Company, in whole or in part, for United States federal income tax purposes. “Investment Company Event” means the receipt by the Company of an opinion of independent counsel to the Company to the effect that there exist a material risk that the Company is or, within one hundred twenty (120) calendar days after the receipt of such opinion will be, required to register as an investment company pursuant to the Investment Company Act of 1940, as amended.

Redemption on or after Fifth Anniversary. On or after the fifth anniversary of the Issue Date, subject to the provisions of Section 4(f) (Regulatory Approvals) hereof, this Subordinated Note shall be redeemable at the option of and by the Company, in whole or in part at any time and from time to time upon any Interest Payment Date, at an amount equal to 100% of the outstanding principal amount being redeemed plus accrued but unpaid interest, to but excluding the redemption date, but in all cases in a principal amount with integral multiples of $1,000. In addition, on or after the fifth anniversary of the Issue Date, subject to Section 4(f) (Regulatory Approvals), the Company may redeem all or a portion of the Subordinated Notes, at any time upon the occurrence of a Tier 2 Capital Event, Tax Event or an Investment Company Event.

Partial Redemption. If less than the then outstanding principal amount of this Subordinated Note is redeemed, (i) a new Subordinated Note shall be issued representing the unredeemed portion without charge to the applicable Noteholder, and (ii) such redemption shall be effected on a pro rata basis as to the Noteholders. For purposes of clarity, upon a partial redemption, a like percentage of the principal amount of every Subordinated Note held by every Noteholder shall be redeemed.

No Redemption at Option of Noteholder. This Subordinated Note is not subject to redemption at the option of any Noteholder.

Effectiveness of Redemption. If notice of redemption has been duly given and notwithstanding that this Subordinated Note has been called for redemption but has not yet been surrendered for cancellation, on and after the date fixed for redemption interest shall cease to accrue on the portion of this Subordinated Note called for redemption; this Subordinated Note shall no longer be deemed outstanding with respect to the portion called for redemption and all rights with respect to the portion of this Subordinated Note called for redemption shall forthwith on such date fixed for redemption cease and terminate unless the Company shall default in the payment of the redemption price, subject only to the right of the Noteholder to receive the amount payable on such redemption, without interest.

Regulatory Approvals. Any such redemption shall be subject to receipt of any and all required federal and state regulatory approvals or non-objections, as applicable, including, but not limited to, the consent of the Federal Reserve to the extent then required by applicable law. In the case of any

A-14

redemption of this Subordinated Note pursuant to paragraphs (b) or (c) of this Section 4, the Company will give the Noteholder notice of redemption, which notice shall indicate the aggregate principal amount of Subordinated Notes to be redeemed, not less than thirty (30) nor more than forty-five (45) calendar days prior to the proposed redemption date.

Purchase and Resale of the Subordinated Notes. Subject to any required federal and state regulatory approvals and the provisions of this Subordinated Note, the Company shall have the right to purchase any of the Subordinated Notes at any time in the open market, private transactions or otherwise. If the Company purchases any Subordinated Notes, it may, in its discretion, hold, resell or cancel any of the purchased Subordinated Notes.

Events of Default; Acceleration. Each of the following events shall constitute an “Event of Default”:

the entry of a decree or order for relief in respect of the Company by a court having jurisdiction in the premises in an involuntary case or proceeding under any applicable bankruptcy, insolvency, or reorganization law, now or hereafter in effect of the United States or any political subdivision thereof, and such decree or order will have continued unstayed and in effect for a period of ninety (90) consecutive calendar days;

the commencement by the Company of a voluntary case under any applicable bankruptcy, insolvency or reorganization law, now or hereafter in effect of the United States or any political subdivision thereof, or the consent by the Company to the entry of a decree or order for relief in an involuntary case or proceeding under any such law;

the Company (i) becomes insolvent or is unable to pay its debts as they mature, (ii) makes an assignment for the benefit of creditors, (iii) admits in writing its inability to pay its debts as they mature, or (iv) ceases to be a bank holding company or financial holding company under the Bank Holding Company Act of 1956, as amended;

the failure of the Company to pay any installment of interest on any of the Subordinated Notes as and when the same will become due and payable, and the continuation of such failure for a period of thirty (30) calendar days;

the failure of the Company to pay all or any part of the principal of any of the Subordinated Notes as and when the same will become due and payable;

the liquidation of the Company (for the avoidance of doubt, “liquidation” does not include any merger, consolidation, sale of equity or assets or reorganization (exclusive of a reorganization in bankruptcy) of the Company or any of its Subsidiaries);

the failure of the Company to perform any other covenant or agreement on the part of the Company contained in the Subordinated Notes, and the continuation of such failure for a period of thirty (30) calendar days after the date on which notice specifying such failure, stating that such notice is a “Notice of Default” hereunder and demanding that the Company remedy the same, will have been given, in the manner set forth in Section 21 (Notices), to the Company by a Noteholder; and

A-15

the default by the Company under any bond, debenture, note or other evidence of indebtedness for money borrowed by the Company having an aggregate principal amount outstanding of at least $5,000,000, whether such indebtedness now exists or is created or incurred in the future, which default (i) constitutes a failure to pay any portion of the principal of such indebtedness when due and payable after the expiration of any applicable grace period or (ii) results in such indebtedness becoming due or being declared due and payable prior to the date on which it otherwise would have become due and payable without, in the case of clause (i), such indebtedness having been discharged or, in the case of clause (ii), such indebtedness having been discharged or such acceleration having been rescinded or annulled.

Unless the principal amount of this Subordinated Note already shall have become due and payable, if an Event of Default set forth in Section 5(a) or Section 5(b) shall have occurred and be continuing, Noteholders holding not less than twenty percent (20%) in aggregate principal amount of the Subordinated Notes at the time outstanding, by notice in writing to the Company, may declare the principal amount of all outstanding Subordinated Notes to be due and payable immediately and, upon any such declaration, the same shall become and shall be immediately due and payable. The Company waives demand, presentment for payment, notice of nonpayment, notice of protest, and all other notices. Notwithstanding the foregoing, because the Company will treat the Subordinated Notes as Tier 2 Capital, upon the occurrence of an Event of Default other than an Event of Default described in Section 5(a) or Section 5(b), the Noteholders may not accelerate the Maturity Date of the Subordinated Notes and make the principal of, and any accrued and unpaid interest on, the Subordinated Notes, immediately due and payable. The Company, within thirty (30) calendar days after the receipt of written notice from any Noteholder of the occurrence of an Event of Default with respect to this Subordinated Note, shall mail to all Noteholders, at their addresses shown on the Security Register (as defined in Section 13 (Registration of Transfer, Security Register) below), such written notice of Event of Default, unless such Event of Default shall have been cured or waived before the giving of such notice as certified by the Company in writing to the Noteholder or Noteholders who provided written notice of such Event of Default.

Failure to Make Payments. In the event of any failure by the Company to make any required payment of principal or interest on this Subordinated Note (and in the case of payment of interest, such failure to pay shall have continued for thirty (30) calendar days), the Company will, upon demand of the Noteholders, pay to the Noteholders the amount then due and payable on this Subordinated Note for principal and interest (without acceleration of the Subordinated Note in any manner), with interest on the overdue principal and interest at the rate per annum borne by the Subordinated Note, to the extent permitted by applicable law. If the Company fails to pay such amount upon such demand, the Noteholders may, among other things, 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 and collect the amounts adjudged or decreed to be payable in the manner provided by law out of the property of the Company.

Upon the occurrence of a failure by the Company to make any required payment of principal or interest on this Subordinated Note, or an Event of Default until such Event of Default is cured by the Company, or waived by the Noteholders in accordance with Section 16 (Waiver and Consent) hereof, except as may be required by any federal or state bank regulatory agency, the Company shall not: (a) declare or pay any dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment

A-16

with respect to, any of the Company’s capital stock; (b) make any payment of principal or interest or premium, if any, on or repay, repurchase or redeem any indebtedness of the Company that ranks equal with or junior to the Subordinated Notes; or (c) make any payments under any guarantee of indebtedness, which guarantee ranks equal with or junior to the Subordinated Notes, other than (i) any dividends or distributions in shares of, or options, warrants or rights to subscribe for or purchase shares of, any class of the Company’s common stock; (ii) any declaration of a non-cash dividend in connection with the implementation of a shareholders’ rights plan, or the issuance of stock under any such plan in the future, or the redemption or repurchase of any such rights pursuant thereto; (iii) as a result of a reclassification of the Company’s capital stock or the exchange or conversion of one class or series of the Company’s capital stock for another class or series of the Company’s capital stock; (iv) the purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged; or (v) purchases of any class of the Company’s common stock related to the issuance of common stock or rights under any benefit plans for the Company’s directors, officers or employees or any of the Company’s dividend reinvestment plans (the foregoing clauses (i) through (v) are collectively referred to as the “Permitted Dividends”).

Affirmative Covenants of the Company.

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

A-18

To the extent permitted by applicable law, interest shall accrue, at the rate at which interest accrues on the principal of this Subordinated Note, on any amount of principal or interest on this Subordinated Note not paid when due. All payments on this Subordinated Note shall be applied first against interest due hereunder; and then against principal due hereunder. The Noteholder acknowledges and agrees that the payment of all or any portion of the outstanding principal amount of this Subordinated Note and all interest hereon shall be pari passu in right of payment and in all other respects to the other Subordinated Notes. In the event that the Noteholder receives payments in excess of its pro rata share of the Company’s payments to the Noteholders of all of the Subordinated Notes, then the Noteholder shall hold in trust all such excess payments for the benefit of the holders of the other Subordinated Notes and shall pay such amounts held in trust to such other Noteholders upon demand by such Noteholders.

Upon surrender or presentation of the Subordinated Note for exchange or registration of transfer, the Company, or the Registrar, as the case may be, shall execute and deliver in exchange therefor a Subordinated Note or Subordinated Notes of like aggregate principal amount, each in a minimum denomination of $250,000 or any amount in excess thereof which is an integral multiple of $1,000 (and, in the absence of an opinion of counsel satisfactory to the Company to the contrary, bearing the restrictive legend(s) set forth hereinabove) and that is or are registered in such name or names requested by the Noteholder. Any Subordinated Note presented or surrendered for registration of transfer or for exchange shall be duly endorsed and accompanied by a written instrument of transfer in such form as is attached hereto and incorporated herein, duly executed by the Noteholder or its attorney duly authorized in writing, with such tax identification number or other information for each person in whose name a Subordinated Note is to be issued, and accompanied by evidence of compliance with any restrictive legend(s) appearing on such Subordinated Note or Subordinated Notes as the Company may reasonably request to comply with applicable law. No exchange or registration of transfer of this Subordinated Note shall be made on or after (i) the fifteenth (15th) calendar day immediately preceding the Maturity Date or (ii) the due delivery of notice of redemption.

Priority. The Subordinated Notes ranks pari passu among themselves and, in the event of any insolvency proceeding, dissolution, assignment for the benefit of creditors, reorganization, restructuring of debt, marshaling of assets and liabilities or similar proceeding or any liquidation or winding up of the Company with all other present or future unsecured subordinated debt obligations of the Company, except any unsecured subordinated debt that, pursuant to its express terms, is senior or subordinate in right of payment to the Subordinated Notes (including all Senior Indebtedness).

Ownership. Prior to due presentment of this Subordinated Note for registration of transfer, the Company may treat the Noteholder in whose name this Subordinated Note is registered in the Security Register as the absolute owner of this Subordinated Note for receiving payments of principal and interest on this Subordinated Note and for all other purposes whatsoever, whether or not this Subordinated Note be overdue, and the Company shall not be affected by any notice to the contrary.

Waiver and Consent.

Any consent or waiver given by the Noteholders or otherwise in accordance with the terms hereof shall be conclusive and binding upon such Noteholder and upon all subsequent holders of this Subordinated Note and of any Subordinated Note issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Subordinated Note. No delay or omission of the Noteholder to exercise any right or remedy accruing upon any Event of Default shall impair such right or remedy or constitute a waiver of any such Event of Default. Any insured depository institution which shall be a Noteholder or which otherwise shall have any beneficial ownership interest in this Subordinated Note shall, by its acceptance of this Subordinated Note (or beneficial interest therein), be deemed to have waived any right of offset with respect to the repayment of the indebtedness evidenced thereby.

No waiver or amendment of any term, provision, condition, covenant or agreement in the Subordinated Notes shall be effective except with the consent of the Noteholders holding more than fifty percent (50%) in aggregate principal amount (excluding any Subordinated Notes held by the Company or any of its Affiliates) of the Subordinated Notes at the time outstanding; provided, however,

A-22

that without the consent of each Noteholder of an affected Subordinated Note, no such amendment or waiver may: (i) reduce the principal amount of such Subordinated Note; (ii) reduce the rate of or change the time for payment of interest on such Subordinated Note; (iii) extend the maturity of such Subordinated Note; (iv) change the currency in which payment of the obligations of the Company under the Subordinated Notes are to be made; (v) lower the percentage of aggregate principal amount of outstanding Subordinated Notes required to approve any amendments of the Subordinated Notes; (vi) make any changes to Section 5 (Events of Default; Acceleration); Section 6 (Failure to Make Payments); Section 7 (Affirmative Covenants of the Company); Section 8 (Negative Covenants of the Company) or Section 16 (Waiver and Consent) of the Subordinated Notes that adversely affects the rights of any Noteholder; or (vii) disproportionately affect any of the Noteholders of the then outstanding Subordinated Notes. Notwithstanding the foregoing, the Company may amend or supplement the Subordinated Notes without the consent of the Noteholder to cure any ambiguity, defect or inconsistency or to provide for uncertificated Subordinated Note in addition to or in place of certificated Subordinated Note, or to make any change that does not adversely affect the rights of any Noteholder of any of the Subordinated Notes. No failure to exercise or delay in exercising, by any Noteholder of the Subordinated Notes, of any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege preclude any other or further exercise thereof, or the exercise of any other right or remedy provided by law, except as restricted hereby. The rights and remedies provided in this Subordinated Note are cumulative and not exclusive of any right or remedy provided by law or equity. No notice or demand on the Company in any case shall, in itself, entitle the Company to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the Noteholders to any other or further action in any circumstances without notice or demand. No consent or waiver, expressed or implied, by the Noteholders to or of any breach or default by the Company in the performance of its obligations hereunder shall be deemed or construed to be a consent or waiver to or of any other breach or default in the performance of the same or any other obligations of the Company hereunder. Failure on the part of the Noteholders to complain of any acts or failure to act or to declare an Event of Default, irrespective of how long such failure continues, shall not constitute a waiver by the Noteholders of their rights hereunder or impair any rights, powers or remedies on account of any breach or default by the Company.

Absolute and Unconditional Obligation of the Company. No provisions of the Subordinated Note shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal and interest on this Subordinated Note at the times, places and rate, and in the coin or currency, herein prescribed.

Successors and Assigns. This Subordinated Note shall be binding upon the Company and inure to the benefit of the Noteholder and its respective successors and permitted assigns. The Noteholder may, subject to the terms set forth in the restrictive legend(s) set forth hereinabove, assign all, or any part of, or any interest in, the Noteholder’s rights and benefits hereunder, upon execution of the Assignment Form attached hereto. To the extent of any such assignment, such assignee shall have the same rights and benefits against the Company and shall agree to be bound by and to comply with the terms and conditions of the Purchase Agreement as it would have had if it were the Noteholder hereunder.

A-23
