Ladies and Gentlemen:

PlainsCapital Corporation, a Texas corporation (the “Company”), proposes to issue and sell to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representative (the “Representative”), an aggregate of [    ] shares of Common Stock, par value $0.001, of the Company (the “Common Stock”), and certain shareholders of the Company named in Schedule 2 hereto (the “Selling Shareholders”) propose to sell to the several Underwriters an aggregate of [    ] shares of Common Stock of the Company (collectively, the “Underwritten Shares”). In addition, the Company proposes to issue and sell, at the option of the Underwriters, up to an additional [    ] shares of Common Stock of the Company (the “Option Shares”). The Underwritten Shares and the Option Shares are herein referred to as the “Shares”. The Underwritten Shares proposed to be sold by the Selling Shareholders are currently issued from the class of the Company’s Original Common Stock, par value $0.001 (the “Original Common Stock”) but will be converted prior to the Closing Date (as hereafter defined) into an equal number of shares of Common Stock. For the purposes hereof, the term Shares shall be deemed to include such Original Common Stock. The shares of common stock (including Common Stock and Original Common Stock) of the Company to be outstanding after giving effect to the sale of the Shares are referred to herein as the “Stock”.

The Company hereby acknowledges that it has, and the Selling Shareholders hereby acknowledge that the Company has, requested Stephens Inc. (“Stephens”) to administer a directed share program (the “Directed Share Program”) under which up to [    ] Underwritten Shares to be purchased by the Underwriters (the “Reserved Shares”), shall be reserved for sale at the initial public offering price to the Company’s officers, directors, employees and consultants and other persons having a relationship with the Company as designated by the Company (the “Directed Share Participants”) as part of the distribution of the Shares by the Underwriters, subject to the terms of this Agreement, the applicable rules, regulations and interpretations of the Financial Industry Regulatory Authority, Inc. (“FINRA”) and all other applicable laws, rules and regulations. The number of Shares available for sale to the general public will be reduced to the extent that Directed Share Participants purchase Reserved Shares. The Underwriters may offer any Reserved Shares not purchased by Directed Share Participants to the general public on the same basis as the other Shares being sold hereunder. The Company has supplied Stephens with the names,

1

addresses and telephone numbers of the individuals or other entities which the Company has designated to be participants in the Directed Share Program. It is understood that any number of those so designated to participate in the Directed Share Program may decline to do so.

The Company and the Selling Shareholders hereby confirm their agreement with the several Underwriters concerning the purchase and sale of the Shares, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement (File No. 333-161548), including a prospectus, relating to the Shares. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means each prospectus included in such registration statement (and any amendments thereto) before it becomes effective and that is furnished by the Company to the Underwriters for distribution in connection with the offering of the Shares, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Shares. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

At or prior to the Applicable Time (as defined below), the Company had prepared the following information (collectively, with the pricing information set forth on Annex B, the “Pricing Disclosure Package”): a Preliminary Prospectus dated [    ], 2009 [and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex B hereto].

“Applicable Time” means [    ] [A/P].M., New York City time, on [    ], 2009.

2. Purchase of the Shares by the Underwriters. (a) The Company agrees to issue and sell, and each of the Selling Shareholders agrees, severally and not jointly, to sell, the Underwritten Shares to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase at a price per share (the “Purchase Price”) of $[    ] from the Company the respective number of Underwritten Shares (to be adjusted by you so as to eliminate fractional shares) determined by multiplying the aggregate number of Underwritten Shares to be sold by the Company by a fraction, the numerator of which is the aggregate number of Underwritten Shares to be purchased by such Underwriter as set forth opposite the name of such Underwriter in Schedule 1 hereto and the denominator of which is the aggregate number of Underwritten Shares, and from each Selling Shareholder that number of Underwritten Shares (to be adjusted by you so as to eliminate fractional shares) determined by multiplying the aggregate number of Underwritten Shares to be sold by each such Selling Shareholder as set forth opposite the name of such Selling Shareholder in Schedule 2 hereto by a fraction, the numerator of which is the aggregate number of Underwritten Shares to be purchased by such Underwriter as set forth opposite the name of such Underwriter in Schedule 1 hereto and the denominator of which is the aggregate number of Underwritten Shares. The public offering

2

price of the Shares is not in excess of the price recommended by Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC, acting as a “qualified independent underwriter” within the meaning of NASD Rule 2720 of the FINRA.

In addition, the Company agrees to issue and sell the Option Shares to the several Underwriters as provided in this Agreement, and the Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from the Company the Option Shares at the Purchase Price less an amount per share equal to any dividends or distributions declared by the Company and payable on the Underwritten Shares but not payable on the Option Shares.

If any Option Shares are to be purchased, the number of Option Shares to be purchased by each Underwriter shall be the number of Option Shares which bears the same ratio to the aggregate number of Option Shares being purchased as the number of Underwritten Shares set forth opposite the name of such Underwriter in Schedule 1 hereto (or such number increased as set forth in Section 12 hereof) bears to the aggregate number of Underwritten Shares, subject, however, to such adjustments to eliminate any fractional Shares as the Representative in its sole discretion shall make.

The Underwriters may exercise the option to purchase the Option Shares at any time in whole, or from time to time in part, on or before the thirtieth day following the date of the Prospectus, by written notice from the Representative to the Company and the Attorneys-in-Fact (as defined below). Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised and the date and time when the Option Shares are to be delivered and paid for, which may be the same date and time as the Closing Date (as hereinafter defined) but shall not be earlier than the Closing Date or later than the tenth full business day (as hereinafter defined) after the date of such notice (unless such time and date are postponed in accordance with the provisions of Section 12 hereof). Any such notice shall be given at least two business days prior to the date and time of delivery specified therein.

(a) The Company and the Selling Shareholders understand that the Underwriters intend to make a public offering of the Shares as soon after the effectiveness of this Agreement as in the judgment of the Representative is advisable, and initially to offer the Shares on the terms set forth in the Prospectus. The Company and the Selling Shareholders acknowledge and agree that the Underwriters may offer and sell Shares to or through any affiliate of an Underwriter.

(b) Payment for the Shares shall be made by wire transfer in immediately available funds to the accounts specified by the Company and, with regard to payment to the Selling Shareholders, the Attorneys-in-Fact or any of them, to the Representative in the case of the Underwritten Shares, at the offices of Davis Polk & Wardwell LLP, 450 Lexington Avenue, New York, NY 10017, at 10:00 A.M., New York City time, on [    ], 2009, or at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representative, the Company and the Attorneys-in-Fact may agree upon in writing or, in the case of the Option Shares, on the date and at the time and place specified by the Representative in the written notice of the Underwriters’ election to purchase such Option Shares. The time and date of such payment for the Underwritten Shares is referred to herein as the “Closing Date”, and the time and date for such payment for the Option Shares, if other than the Closing Date, is herein referred to as the “Additional Closing Date”.

Payment for the Shares to be purchased on the Closing Date or the Additional Closing Date, as the case may be, shall be made against delivery to the Representative for the respective accounts of the several Underwriters of the Shares to be purchased on such date registered in such names and in such denominations as the Representative shall request in writing not later than two full business days prior to the Closing Date or the Additional Closing Date, as the case may be, with any transfer taxes payable in connection with the sale of such Shares duly paid by the Company and the Selling Shareholders, as

3

applicable. Delivery of the Shares shall be made through the facilities of The Depository Trust Company (“DTC”) unless the Representative shall otherwise instruct. The specimen certificate for the Shares will be made available for inspection and packaging by the Representative not later than 1:00 P.M., New York City time, on the business day prior to the Closing Date or the Additional Closing Date, as the case may be.

(c) Each of the Company and each Selling Shareholder acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company and the Selling Shareholders with respect to the offering of Shares contemplated hereby (including in connection with determining the terms of the offering) and not as a financial advisor or a fiduciary to, or an agent of, the Company, the Selling Shareholders or any other person. Additionally, neither the Representative nor any other Underwriter is advising the Company, the Selling Shareholders or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company and the Selling Shareholders shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and the Underwriters shall have no responsibility or liability to the Company or the Selling Shareholders with respect thereto. Any review by the Underwriters of the Company, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company or the Selling Shareholders.

The Company agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, (ii) any untrue statement or alleged untrue statement of a material fact contained in the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the

24

circumstances under which they were made, not misleading or (iii) the Directed Share Program, except, with respect to clauses (i) and (ii), insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information (x) relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below or (y) relating to any non-executive officer or non-director Selling Shareholder furnished to the Company in writing by such Selling Shareholder expressly for use therein except to the extent with respect to this sub-clause (y) that the Company has knowledge that such information is untrue or misleading, and except, with respect to clause (iii), insofar as such loss, claim, damage or liability is finally judicially determined to have resulted from the gross negligence or willful misconduct of the Underwriters with respect to the Directed Share Program.

Without limitation of and in addition to its obligations under the other subsections of this Section 9, the Company agrees to indemnify and hold harmless Stephens, its affiliates, directors and officers and each person, if any, who controls Stephens within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred) which, jointly or severally, Stephens or any such person may incur related to, arising out of, or in connection with, the Directed Share Program under the Securities Act, the Exchange Act, the common law or otherwise, including such losses, claims, damages or liabilities that are or were caused by the failure of any Directed Share Participant to pay for and accept delivery of Reserved Shares that the Directed Share Participant has agreed to purchase, except insofar as such loss, claim, damage or liability is finally judicially determined to have resulted from the gross negligence or willful misconduct of Stephens in administering the Directed Share Program.

The Company also agrees to indemnify and hold harmless, Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC, its affiliates, directors and officers and each person, if any, who controls Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred) as a result of Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its participation as a “qualified independent underwriter” within the meaning of NASD Rule 2720 of FINRA in connection with the offering of the Shares, except insofar as such loss, claim, damage or liability (i) arises out of, or is based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any non-executive officer or non-director Selling Shareholder furnished to the Company in writing by such Selling Shareholder expressly for use in any of the documents listed in the first paragraph of this Section 9(a) except to the extent that the Company has knowledge that such information is untrue or misleading or (ii) is finally judicially determined to have resulted from the gross negligence or willful misconduct of Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its participation as a “qualified independent underwriter”.

25

furnished to the Company in writing by such Underwriter through the Representative expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Pricing Disclosure Package, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (c) below or (ii) with respect to the Directed Share Program, insofar as such loss, claim, damage or liability is finally judicially determined to have resulted from the gross negligence or willful misconduct of the Underwriters with respect to the Directed Share Program.

Each of the Selling Shareholders, severally and not jointly, also agrees to indemnify and hold harmless Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC, its affiliates, directors and officers and each person, if any, who controls Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages and liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred) as a result of Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its participation as a “qualified independent underwriter” within the meaning of NASD Rule 2720 of FINRA in connection with the offering of the Shares, except insofar as such loss, claim, damage or liability is finally judicially determined to have resulted from the gross negligence or willful misconduct of Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its participation as a “qualified independent underwriter”.

Irrespective of the foregoing two paragraphs of this Section 9(b), a Selling Shareholder will only be liable in any case to the extent, but only to the extent, that any such loss, claim, damage or liability arises out of, or is based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with information furnished to the Company in writing by such Selling Shareholder expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Pricing Disclosure Package; provided, however, that in no case shall any Selling Shareholder be liable or responsible for any amount in excess of the proceeds (net of the underwriting discount but before deducting other expenses) received by such Selling Shareholder from the sale of Shares by such Selling Shareholder pursuant to the transactions contemplated hereby.

(c) Indemnification of the Company and the Selling Shareholders. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each of the Selling Shareholders to the same extent as the indemnity set forth in the first paragraph of (a) above, but only with respect to any losses, claims, damages or liabilities (including, without limitation, legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred) that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Pricing Disclosure Package, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: the concession and reallowance figures appearing in the [3^rd] paragraph under the caption “Underwriting”, the information contained in the [14^th] paragraph referring to market making activities under the caption “Underwriting” and the information contained in the first sentence of the [18^th] paragraph referring to public offerings outside the United States, insofar as such sentence relates to the Underwriters.

(d) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to the preceding paragraphs of this Section 9, such person

26

(the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 9 except to the extent that it has been materially prejudiced (through the material impairment or forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under the preceding paragraphs of this Section 9. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred upon receipt from the Indemnified Person of a written request for payment thereof accompanied by a written statement with reasonable supporting detail of such fees and expenses; provided, however, that if indemnity may be sought pursuant to the second or third paragraph of Section 9(a) or 9(b) above in respect of such proceeding, then in addition to such separate firm of the Underwriters, their affiliates and such control persons of the Underwriters, the Indemnifying Person shall be liable for the fees and expenses of not more than one separate firm (in addition to any local counsel) for each of (i) Stephens in its capacity as administrator of the Directed Share Program and (ii) Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its capacity as a “qualified independent underwriter”, including their respective affiliates, directors, officers and all persons, if any, who control Stephens or Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by J.P. Morgan Securities Inc., any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company and any such separate firm for the Selling Shareholders shall be designated in writing by the Attorneys-in-Fact or any one of them. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form

27

and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(e) Contribution. If the indemnification provided for in paragraphs (a), (b), and (c) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Shareholders, on the one hand, and the Underwriters, Stephens in its capacity as administrator of the Directed Share Program or Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its capacity as a “qualified independent underwriter”, as the case may be, on the other, from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Selling Shareholders, on the one hand, and the Underwriters, Stephens in its capacity as administrator of the Directed Share Program or Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its capacity as a “qualified independent underwriter”, as the case may be, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Shareholders, on the one hand, and the Underwriters or Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its capacity as a “qualified independent underwriter”, as the case may be, on the other, shall be deemed to be in the same respective proportions as the net proceeds (net of the underwriting discount but before deducting expenses) received by the Company and the Selling Shareholders from the sale of the Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, or the fee to be received by Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its capacity as a “qualified independent underwriter”, as the case may be, bear to the aggregate offering price of the Shares. The relative benefits received by the Company, on the one hand, and Stephens in its capacity as administrator of the Directed Share Program shall be deemed to be in the same respective proportions as the net proceeds (net of the underwriting discount but before deducting expenses) received by the Company and the Selling Shareholders from the sale of the Reserved Shares and the total underwriting discounts and commissions for the Reserved Shares bear to the aggregate offering price of the Reserved Shares. The relative fault of the Company and the Selling Shareholders, on the one hand, and the Underwriters, Stephens in its capacity as administrator of the Directed Share Program or Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its capacity as a “qualified independent underwriter”, as the case may be on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Selling Shareholders or by the Underwriters, Stephens in its capacity as administrator of the Directed Share Program or Fox-Pitt Kelton Cochran Caronia Waller (USA) LLC in its capacity as a “qualified independent underwriter”, as the case may be, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) Limitation on Liability. The Company, the Selling Shareholders and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9 were determined by pro rata allocation (even if the Selling Shareholders or the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (e) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (e) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 9, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with

28

respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. Furthermore, in no event shall a Selling Shareholder be required to contribute any amount in excess of the amount by which the total proceeds (net of the underwriting discount but before deducting other expenses) received by such Selling Shareholder from the sale of Shares sold by such Selling Shareholder pursuant to the transactions contemplated hereby exceeds the amount of any damages that such Selling Shareholder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 9 are several in proportion to their respective purchase obligations hereunder and not joint. Moreover, the Selling Shareholders’ obligation to contribute pursuant to this Section 9 are several and not joint.

(g) Non-Exclusive Remedies. The remedies provided for in this Section 9 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

10. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

11. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by written notice to the Company and the Selling Shareholders, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Shares, prior to the Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the Exchange, the NYSE AMEX Equities, The Nasdaq Stock Market, the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal, Texas or New York State authorities; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus.

12. Defaulting Underwriter.

(a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company, and in the case of the Closing Date, the Selling Shareholders on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company and the Selling Shareholders shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms. If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company, and in the case of the Closing Date, the Selling Shareholders may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company, counsel for the Selling Shareholders (in the case of the Closing Date) or counsel for the Underwriters may

29

be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 12, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company, and the Selling Shareholders as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company and, in the case of the Closing Date, the Selling Shareholders shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and, in the case of the Closing Date, the Selling Shareholders as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company and the Selling Shareholders shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Shares on the Additional Closing Date shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 12 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 13 hereof and except that the provisions of Section 9 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company, the Selling Shareholders or any non-defaulting Underwriter for damages caused by its default.
