Upon consummation of the Merger, the separate corporate existence of Merger Sub shall terminate.

Section 1.02    Effects of the Merger. The Merger will have the effects set forth in Section 10.008 of the TBOC. The name of the Surviving Corporation will be “TB&T Bancshares, Inc.”

Section 1.03    Certificate of Formation and Bylaws. The certificate of formation and bylaws of TBT, as in effect immediately before the Effective Time, will be the certificate of formation and bylaws of the Surviving Corporation until thereafter changed or amended as provided by applicable Law.

Section 1.05    Effect on Capital Stock. At the Effective Time, by virtue of the Merger and without any further action on the part of FFIN, TBT, Merger Sub or any holder of record of the following securities:

(a)    Each share of FFIN Stock outstanding prior to the Effective Time shall remain one validly issued, fully paid and nonassessable share of FFIN Stock after the Effective Time.

(b)    Except for the Cancelled Shares and Dissenting Shares, each share of common stock, par value $1.00 per share, of TBT (the “TBT Stock”) that is issued and outstanding immediately prior to the Effective Time shall cease to be outstanding and shall automatically be converted into and become the right to receive, without interest, 1.2502 shares of FFIN Stock (the “Exchange Ratio” and such shares, the “Merger Consideration”).

(c)    No certificates representing a fractional share shall be issued by FFIN. In lieu of any fractional share, each holder of TBT Stock entitled to a fractional share, upon surrender of such shares of TBT Stock, shall be entitled to receive from FFIN an amount in cash (without interest), payable in accordance with Section 1.06, rounded to the nearest cent, determined by multiplying the fractional share by $30.28.

2

(d)    All shares of TBT Stock to be converted into the right to receive the Merger Consideration pursuant to this Section 1.05 shall no longer be outstanding and shall automatically be cancelled and cease to exist, and each holder of a certificate that immediately prior to the Effective Time represented any such shares of TBT Stock shall thereafter cease to have any rights with respect to such shares of TBT Stock, except the right to receive the Merger Consideration.

(e)    Any shares of TBT Stock that are owned immediately prior to the Effective Time by TBT, FFIN or their respective Subsidiaries (other than (i) shares of TBT Stock held, directly or indirectly, in trust accounts, managed accounts and the like or otherwise held in a fiduciary capacity that are beneficially owned by third parties, and (ii) shares of TBT Stock held in respect of a debt previously contracted) shall be canceled and extinguished without any conversion thereof or consideration therefor (the “Cancelled Shares”).

(f)    Each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted automatically into and become one newly issued, fully paid and non-assessable share of common stock of the Surviving Corporation.

(g)    If, prior to the Effective Time, the outstanding shares of FFIN Stock or TBT Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Exchange Ratio.

Section 1.06    Exchange Procedures.

(a)    Prior to the Effective Time, FFIN shall appoint an exchange agent (the “Exchange Agent”) to act as the exchange agent hereunder.

(b)    At or promptly after the Effective Time, FFIN shall deposit with or make available to the Exchange Agent for exchange in accordance with this Section 1.06, the certificates or, at FFIN’s option, evidence of shares in book entry form, representing the shares of FFIN Stock to be issued to holders of TBT Stock pursuant to Section 1.05(b) and any cash payable in lieu of fractional shares (collectively, the “Exchange Fund”).

(c)    No later than five (5) Business Days after the Effective Time and subject to FFIN’s receipt of a list of TBT’s shareholders in a format that is reasonably acceptable to the FFIN, FFIN shall, or shall cause the Exchange Agent to, mail to each holder of record immediately prior to the Effective Time of certificates (other than with respect to Cancelled Shares and Dissenting Shares) representing shares of TBT Stock (each, a “Certificate,” it being understood that any reference herein to a “Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of shares of TBT Stock), (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to each Certificate shall pass, only upon delivery of such Certificate (or an affidavit of loss in lieu of such Certificate and, if reasonably required by FFIN or the Exchange Agent, the posting by such holder of TBT Stock of a bond in such amount as FFIN may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Certificate; provided, that the amount of such bond may not exceed the aggregate amount of such shareholder’s portion of the Merger Consideration)) to the Exchange Agent and shall be substantially in such form and have such other provisions as shall be prescribed by the Exchange Agent (the “Letter of Transmittal”), and (ii) instructions for

3

use in surrendering each Certificate in exchange for the Merger Consideration, any cash in lieu of a fractional share of FFIN Stock to be issued or paid in consideration therefor and any dividends or distributions to which such holder is entitled pursuant to this Section 1.06. The TBT shareholders will be entitled to receive their Merger Consideration only after receipt by the Exchange Agent of a properly completed Letter of Transmittal. If a Letter of Transmittal contains an error, is incomplete or is not accompanied by all appropriate Certificates, then the Exchange Agent will notify that TBT shareholder promptly of the need for further information or documentation.

(d)    Within five (5) Business Days after surrender to the Exchange Agent of its Certificate or Certificates, accompanied by a properly completed Letter of Transmittal, or within five (5) Business Days after the Effective Time for any uncertificated shares of TBT Stock held of record in book-entry form (subject to receipt of any customary tax documentation that may be reasonably requested by the Exchange Agent), the Exchange Agent shall deliver to such holder of TBT Stock the Merger Consideration and any cash in lieu of a fractional share of FFIN Stock to be issued or paid in consideration therefor in respect of the shares of TBT Stock represented by such holder’s Certificate or Certificates, and each Certificate surrendered will be canceled. FFIN may, at its option, deliver any shares of FFIN Stock in book-entry form. Until so surrendered, each Certificate shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the Merger Consideration and any cash in lieu of a fractional share of FFIN Stock to be issued or paid in consideration therefor upon surrender of such Certificate in accordance with this Section 1.06, and any dividends or distributions to which such holder is entitled pursuant to this Section 1.06. Notwithstanding anything to the contrary herein, no Certificate or Certificates shall be deemed surrendered to the Exchange Agent prior to the Effective Time.

(e)    No dividends or other distributions with respect to FFIN Stock shall be paid to the holder of any unsurrendered Certificate with respect to the shares of FFIN Stock represented thereby, in each case unless and until the surrender of such Certificate in accordance with this Section 1.06. However, upon surrender of such Certificate, the Merger Consideration, together with all such undelivered dividends or other distributions without interest, shall be delivered and paid with respect to each share represented by such Certificate. Subject to the effect of applicable abandoned property, escheat or similar Laws, following surrender of any such Certificate in accordance with this Section 1.06, the record holder thereof shall be entitled to receive, without interest, (i) the amount of dividends or other distributions, if any, with a record date at or after the Effective Time that are payable with respect to the whole shares of FFIN Stock issuable with respect to such Certificate and not paid, and (ii) at the appropriate payment date, the amount of dividends or other distributions payable with respect to shares of FFIN Stock issuable with respect to such Certificate with a record date after the Effective Time (but before such surrender date) and with a payment date subsequent to the issuance of the FFIN Stock issuable with respect to such Certificate.

(f)    In the event of a transfer of ownership of a Certificate representing TBT Stock prior to the Effective Time that is not registered in the stock transfer records of TBT, the Merger Consideration and any cash in lieu of a fractional share of FFIN Stock to be issued or paid in consideration therefor shall be issued or paid in exchange therefor to a Person other than the Person in whose name the Certificate so surrendered is registered if the Certificate formerly representing such TBT Stock shall be properly endorsed or otherwise be in proper form for transfer and the Person requesting such payment or issuance shall pay any transfer or other similar Taxes required by reason of the payment or issuance to a Person other than the registered holder of the Certificate or establish to the satisfaction of FFIN and the Exchange Agent that the Tax has been paid or is not applicable.

4

(g)    FFIN and the Exchange Agent, as the case may be, shall be entitled to deduct and withhold, if necessary, from any consideration otherwise payable pursuant to this Agreement to any Person such amounts as FFIN or the Exchange Agent, as the case may be, is required to deduct and withhold under the Code, or any provision of state, local or foreign tax law, with respect to the making of such payment. To the extent that amounts are so withheld by FFIN or the Exchange Agent, as the case may be, and remitted to the appropriate Governmental Entity, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to such Person in respect of which such deduction and withholding was made by FFIN or the Exchange Agent, as the case may be.

(h)    Any portion of the Exchange Fund that remains unclaimed by the shareholders of TBT at the expiration of six (6) months after the Effective Time shall be paid to FFIN. In such event, any former shareholders of TBT who have not theretofore complied with this Section 1.06 shall thereafter look only to FFIN with respect to the Merger Consideration, any cash in lieu of any fractional shares and any unpaid dividends and distributions on the FFIN Stock deliverable in respect of each share represented by a Certificate such shareholder holds as determined pursuant to this Agreement, in each case, without any interest thereon.

(i)    Any other provision of this Agreement notwithstanding, none of FFIN, the Surviving Corporation or the Exchange Agent shall be liable to a holder of TBT Stock for any amounts paid or property delivered in good faith to a public official pursuant to any applicable abandoned property, escheat or similar law.

Section 1.07    Tax Treatment. For U.S. federal income Tax purposes, it is intended that the Integrated Mergers together be treated as a single integrated transaction that qualifies as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement and the merger agreement for the Second Step Merger, shall constitute, and are hereby adopted as, a “plan of reorganization” within the meaning of Treasury Regulation Section 1.368-2(g). From and after the date of this Agreement and until the Closing Date, each party hereto shall use its reasonable best efforts to cause the Integrated Mergers to so qualify, and will not knowingly take any action, cause any action to be taken, fail to take any action or cause any action not to be taken, which action or failure to act could reasonably be expected to prevent the Integrated Mergers from qualifying as a “reorganization” within the meaning of Section 368(a) of the Code.

Section 1.08    Modification of Structure. Notwithstanding any provision of this Agreement to the contrary, FFIN may elect, subject to the filing of all necessary applications and the receipt of all required regulatory approvals, to modify the structure of the transactions contemplated hereby so long as (i) there are no material adverse federal or state income tax consequences to the holders of TBT Stock as a result of such modification (taken as a whole and not with respect to any individual holder), (ii) the after tax consideration to be paid to the holders of TBT Stock is not changed in kind or reduced in amount, and (iii) such modification will not be likely to materially delay or jeopardize receipt of any required regulatory approvals or the Closing.

Section 1.09    Dissenting Shareholders. Notwithstanding anything in this Agreement to the contrary, each share of TBT Stock that is outstanding immediately prior to the Effective Time and that is held by shareholders (“Dissenting Shares”) who have not voted such shares in favor of this Agreement, the Merger and the transactions contemplated hereby and who will have otherwise complied with the terms and provisions of Chapter 10, Subchapter H of the TBOC will be entitled to those rights and remedies set forth in Chapter 10, Subchapter H of the TBOC; but if a shareholder fails to perfect, withdraws or otherwise loses any such right or remedy granted by the TBOC, each such Dissenting Shares shall be deemed to have been converted into and to have become exchangeable for, the right to receive the Merger Consideration without any interest thereon in accordance with the provisions of this Article I.

5

Section 1.10    Second Step Merger. As soon as reasonably practicable following the Effective Time, in accordance with the TBOC, FFIN shall cause the Surviving Corporation to be merged with and into FFIN in the Second Step Merger, with FFIN surviving the Second Step Merger and continuing its existence under the Laws of the State of Texas, and the separate corporate existence of the Surviving Corporation ceasing as of the Second Effective Time. In furtherance of the foregoing, FFIN shall cause to be filed with the Texas Secretary of State, in accordance with the TBOC, a certificate of merger relating to the Second Step Merger (the “Second Certificate of Merger”). The Second Step Merger shall become effective as of the date and time specified in the Second Certificate of Merger (such date and time, the “Second Effective Time”). At and after the Second Effective Time, the Second Step Merger shall have the effects set forth in the applicable provisions of the TBOC.

Section 1.11    Bank Merger. Immediately following the Second Step Merger, or at such later time as FFIN may determine in its sole discretion, FFIN will cause the Bank Merger on the terms and subject to the terms and conditions set forth in the Bank Merger Agreement attached hereto as Exhibit “A” (the “Bank Merger Agreement”). FFB shall be the surviving entity in the Bank Merger and, following the Bank Merger, the separate corporate existence of the Bank shall cease. The parties agree that the Bank Merger will become effective immediately after the Second Effective Time or at such later time as FFIN may determine. Prior to or on the date of this Agreement, the board of directors each of FFB and the Bank have approved the Bank Merger Agreement and FFB and the Bank entered into the Bank Merger Agreement. In furtherance of the foregoing, the parties shall execute and cause to be filed applicable articles or certificates of merger and such other documents as are necessary to effectuate the Bank Merger.

ARTICLE II

Section 4.09    Regulatory Compliance.

(a)    Except as set forth on Confidential Schedule 4.09, FFIN is not subject to any cease-and-desist or other Order or enforcement action issued by, or is a party to any written agreement, consent agreement or memorandum of understanding with, or is a party to any commitment letter or similar undertaking to, or is subject to any Order or directive by, or has been ordered to pay any civil penalty by, or is a recipient of a supervisory letter from, or has adopted any board resolutions at the request or suggestion of any Regulatory Agency or other Governmental Entity that restricts the conduct of its business or that relates to its capital adequacy, its ability to pay dividends, its credit or risk management policies, its management or its business.

FFIN is “well-capitalized” (as that term is defined in 12 C.F.R. § 225.2(r)) and “well managed” (as that term is defined is 12 C.F.R. § 225.2(s)).

None of the information supplied or to be supplied by FFIN or any of its directors, officers, employees or agents for inclusion in the Proxy Statement/Prospectus shall, at the date the Proxy Statement/Prospectus is mailed to the shareholders of TBT and, as the Proxy Statement/Prospectus may be amended or supplemented, at the time of the Shareholders’ Meeting, contain any untrue statement of a material fact or omit to state any material fact with respect to FFIN or any Subsidiary of FFIN necessary in order to make the statements therein with respect to FFIN or any Subsidiary of FFIN, in light of the circumstances under which they are made, not misleading or necessary to correct any statement in any earlier communication with respect to the solicitation of any proxy for the Shareholders’ Meeting. All documents that FFIN is responsible for filing with any regulatory or governmental agency in connection with the Merger shall comply with respect to FFIN in all material respects with the provisions of applicable Law.

34

mechanical or photographic process, whether computerized or not) which (including all means of access thereto and therefrom) are not under the exclusive ownership and direct control of FFIN or its accountants. FFIN (and each of its Subsidiaries) has devised, established and maintained a system of “internal controls over financial reporting” (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that is sufficient to provide reasonable assurance (i) regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP (except as otherwise required by RAP), (ii) that receipts and expenditures of FFIN and its Subsidiaries are being made only in accordance with authorizations of management and the FFIN Board, and (iii) regarding prevention or timely detection of the unauthorized acquisition, use or disposition of FFIN’s and its Subsidiaries’ assets that could have a material effect on FFIN’s financial statements. FFIN’s “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) are reasonably designed to ensure that information required to be disclosed by FFIN in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that all such information is accumulated and communicated to FFIN’s management as appropriate to allow timely decisions regarding required disclosure and to make the certifications of the chief executive officer and chief financial officer of FFIN required under the Exchange Act with respect to such reports. FFIN has disclosed, based on its most recent evaluation prior to the date of this Agreement, to FFIN’s auditors and the audit committee of the FFIN Board (i) any significant deficiencies and material weaknesses in the design or operation of internal controls over financial reporting which are reasonably likely to adversely affect in any material respect FFIN’s ability to record, process, summarize and report financial information, and (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in FFIN’s internal controls over financial reporting. For purposes of this Agreement, the terms “significant deficiency” and “material weakness” shall have the meaning assigned to them in Public Company Accounting Oversight Board Auditing Standard 5, as amended and in effect on the date of this Agreement.

Section 4.13    Taxes.

(a)    FFIN and each of its Subsidiaries have duly and timely filed all federal, state and other material Tax Returns that they were required to file under applicable Laws with the appropriate Governmental Entity. All such Tax Returns were correct and complete in all material respects and have been prepared in compliance with all applicable Laws and all material Taxes due and owing by FFIN and each of its Subsidiaries have been timely and properly paid.

(b)    FFIN and each of its Subsidiaries have collected or withheld and duly paid to the appropriate Governmental Entity all material Taxes required to have been collected or withheld and so paid in connection with amounts paid or owing to any employee, independent contractor, creditor, shareholder or other third party.

To the Knowledge of FFIN, no taxing authority has threatened in writing to assess additional Taxes for any period for which Tax Returns have been filed.

(d)    Neither FFIN nor any of its Subsidiaries has participated in a reportable or listed transaction as defined under Section 6011 and 6111 of the Code and Treasury Regulation § 1.6011-4. Neither FFIN nor any of its Subsidiaries has been required to disclose on its federal income Tax Returns any position that could give rise to a substantial understatement of federal income Tax within the meaning of Section 6662 of the Code.

35

(e)    Neither FFIN nor any of its Subsidiaries is aware of any fact or circumstance that reasonably could be expected to prevent the Integrated Mergers from qualifying as a reorganization within the meaning of Section 368(a) of the Code.

Section 4.14    Employee Benefit Plans. All Employee Plans that (i) are sponsored, maintained, or contributed to, by FFIN and any of its Subsidiaries, or with respect to which FFIN and any of its Subsidiaries has or could reasonably be expected to have any liability thereunder and (ii) provide benefits to, or for the welfare of, any current of former officer, director, independent contractor, employee, or service provider of FFIN or any of its Subsidiaries, or the dependents or spouses of any such Person, regardless of whether funded (the “FFIN Employee Plans”), have been maintained and operated in material compliance with applicable Law and the terms of the plans. There have been no prohibited transactions (as defined in Code §4975(c)(1)), breaches of fiduciary duty or any other breaches or violations of any Law applicable to the FFIN Employee Plans that would directly or indirectly subject FFIN, any of its Subsidiaries, or any FFIN Employee Plan to any taxes, penalties, or other liabilities (including any liability arising from any indemnification agreement or policy), except as would not reasonably be expected to result in a material liability. Except as set forth on Confidential Schedule 4.14, either FFIN nor any corporation or trade or business that is a member of a controlled group with FFIN for purposes of Title IV of ERISA or Code §414 currently maintains, contributes to, or has an obligation to contribute to, or during the six year period ending on the Closing Date, has maintained, contributed to, or had an obligation to contribute to, (i) an “employee pension benefit plan” (as defined under ERISA § 3(2)) that is subject to Title IV or Code §412, (ii) a “multiple employer plan” (as described in Code §413(c)), (iii) a “multiemployer plan” (as defined in ERISA §3(37)) or (iv) a “multiple employer welfare arrangement” (as defined in ERISA §3(40)). No written or oral representations have been made by or on behalf of FFIN or any of its Subsidiaries to any employee or former employee of FFIN or any of its Subsidiaries promising or guaranteeing any employer payment or funding for the continuation of medical, dental, life or disability coverage or any other welfare benefit (as defined in ERISA §3(1)) for any period of time beyond the end of the current plan year (except to the extent of coverage required under Code §4980B).

Section 4.15    Representations Not Misleading. No representation or warranty by FFIN contained in this Agreement, nor any written statement, exhibit or schedule furnished to TBT by FFIN under and pursuant to this Agreement, contains or will contain on the Closing Date any untrue statement of a material fact or omits or will omit to state a material fact necessary to make the statements contained herein or therein, in light of the circumstances under which it was or will be made, not misleading and such representations and warranties would continue to be true and correct following disclosure to any Governmental Entity having jurisdiction over FFIN or their properties of the facts and circumstances upon which they were based.

Section 4.16    No Other Representations or Warranties. Except as expressly set forth in Article IV of this Agreement, none of FFIN, its Subsidiaries or any other Person is making or has made, and none of them shall have liability in respect of, any written or oral representation or warranty, express or implied, at Law, in equity or otherwise, with respect to FFIN or any of its Subsidiaries or otherwise, and whether express or implied, at Law, in equity or otherwise, in respect of this Agreement or the transactions contemplated thereby, or in respect of any other matter whatsoever.

FFIN will notify TBT prior to any physical inspections of the Property, and TBT may place reasonable restrictions on the time of such inspections. 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 FFIN, FFIN will (i) notify TBT of any Property for which it intends to conduct such a Secondary Investigation and the reasons for such Secondary Investigation, and (ii) commence such Secondary Investigation, on or prior to the date that is seventy-five (75) days after the date of this Agreement.

On or prior to the date that is ninety (90) days after the

42

date of this Agreement, FFIN will advise TBT in writing as to whether FFIN intends to terminate this Agreement in accordance with Section 9.01 because FFIN disapproves of the results of the Environmental Inspection, Secondary Investigation or other environmental survey. TBT will have the opportunity to correct any objected to violations or conditions to FFIN’s reasonable satisfaction prior to the date that is one hundred five (105) days after the date of this Agreement.

All such participation shall be subject to such terms of such plans as may be in effect from time to time and this Section 6.07 is not intended to give any Continued Employee any rights or privileges superior to those of other similarly situated employees of FFIN or its Subsidiaries. The provisions of this Section 6.07 shall not be deemed or construed so as to provide duplication of similar benefits but, subject to that qualification, FFIN shall, solely for purposes of vesting (but not benefit accrual) and any age or period of service requirements for commencement of participation with respect to any employee benefit plans in which a Continued Employee may participate (excluding any defined benefit pension plan), credit each Continued Employee with his or her term of service with TBT or the Bank (and its predecessor, Texas Enterprise Bank) to the extent such service was recognized under the substantially analogous TBT Employee Plan.

Section 6.08    Conduct of Business in the Ordinary Course. Except as specifically provided for in this Agreement, FFIN shall conduct its business in the ordinary course as heretofore conducted.

Section 6.12    Indemnification.

(a)    For a three (3) year period after the Effective Time, and subject to the limitations contained in applicable Federal Reserve, OCC and FDIC regulations and to any limitations contained in the TBT Constituent Documents, FFIN will indemnify, defend and hold harmless (and advance expenses to) each present director and officer of TBT or the Bank, determined as of the Effective Time (the “Indemnified Parties”), against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring at or before the Effective Time, whether asserted or claimed before, at or after the Effective Time, arising in whole or in part out of or pertaining to the fact that he or she was acting in his or her capacity as a director or officer of the TBT or the Bank to the fullest extent that the Indemnified Party would be entitled under the TBT Constituent Documents, as applicable, in each case as in effect on the date hereof and to the extent permitted by applicable Law.

(b)    Any Indemnified Party wishing to claim indemnification under this Section 6.12, upon learning of any such claim, action, suit, proceeding or investigation, is to promptly notify FFIN, but the failure to so notify will not relieve FFIN of any liability it may have to the Indemnified

50

Party to the extent such failure does not prejudice FFIN. In any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) FFIN will have the right to assume the defense thereof and FFIN will not be liable to an Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by an Indemnified Party in connection with the defense thereof, except that if FFIN elects not to assume such defense or counsel for the Indemnified Party is of the opinion that there are issues which raise conflicts of interest between FFIN and the Indemnified Party, the Indemnified Party may retain counsel reasonably satisfactory to FFIN, and FFIN will pay the reasonable fees and expenses of such counsel for the Indemnified Party (which may not exceed one firm in any jurisdiction), (ii) the Indemnified Party will cooperate in the defense of any such matter, (iii) FFIN will not be liable for any settlement effected without its prior written consent, and (iv) FFIN will have no obligation hereunder if indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable Laws and regulations.

(b)    FFIN and its counsel shall control any audit of TBT’s federal or state Tax Returns for any taxable period whether before or after the Closing Date, and FFIN may settle any such audit in any matter that it determines is appropriate and shall pay all amounts due with respect to any such settlement.

(d)    FFIN will not take any action or omit to take any action that would prevent or impede the Integrated Mergers taken together from qualifying as a reorganization described in Section 368(a) of the Code or satisfying the “continuity of business enterprise” requirement for a “reorganization” as provided in Treasury Regulation Section 1.368-1(d). FFIN will comply, to the extent reasonably expected to be necessary to cause the Integrated Mergers taken together to qualify as a reorganization under the provisions of Section 368(a) of the Code, with all representations, warranties, and covenants contained in the FFIN Certificate.

Section 6.15    Access; Pre-Closing Investigation. Upon reasonable notice and subject to applicable Laws, FFIN will afford the officers, directors, employees, attorneys, accountants, investment bankers and authorized representatives of TBT full access (excluding any information that is prohibited from being disclosed by applicable Law) during normal business hours to the properties, books, contracts and records of FFIN and each of its Subsidiaries as TBT may reasonably require and furnish to TBT during such

51

period all such information concerning FFIN, each of its Subsidiaries and its affairs as TBT may reasonably request, in order that TBT may have full opportunity to make such reasonable investigation as it desires to make of the affairs of FFIN and each of its Subsidiaries, including access sufficient to verify the satisfaction of the conditions precedent to TBT’s obligations described in Article VII of this Agreement. TBT will use its commercially reasonable efforts not to disrupt the normal business operations of FFIN or any of its Subsidiaries. FFIN agrees at any time, and from time to time, to furnish to TBT as soon as practicable, any additional information that TBT may reasonably request. Neither FFIN nor any of its Subsidiaries shall be required to provide access to or to disclose information where such access or disclosure would violate or prejudice the rights of FFIN’s or any of its Subsidiaries’ customers, jeopardize the attorney-client privilege of the institution in possession or control of such information (after giving due consideration to the existence of any common interest, joint defense or similar agreement between the parties) or contravene any Law, rule, regulation, Order, judgment, decree, fiduciary duty or binding agreement entered into prior to the date of this Agreement.

No failure to exercise, nor any delay in exercising any right, power or privilege hereunder by any party hereto will operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder will 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 will 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. Any party may unilaterally waive a right which is solely applicable to it.

WHEREAS, the Merger Agreement provides that all of the issued and outstanding shares of common stock, par value $1.00 per share, of TBT (the “Common Stock”), other than Cancelled Shares and Dissenting Shares, will be exchanged for such consideration as set forth in the Merger Agreement;

WHEREAS, as a condition and inducement to FFIN’s willingness to enter into the Merger Agreement, each of the Shareholders have agreed to vote their shares of Common Stock in favor of approval of the Merger Agreement and the transactions contemplated thereby; and

WHEREAS, FFIN is relying on the agreements set forth herein in incurring expenses in reviewing the business of TBT and The Bank & Trust of ▇▇▇▇▇/College Station, a Texas banking association with its principal offices in Bryan, Texas and a wholly owned subsidiary of TBT (the “Bank”), in proceeding with the filing of applications for regulatory approvals, and in undertaking other actions necessary for the consummation of the Merger, and the Shareholders are benefiting both from such expenditures by FFIN and by the terms of the Merger Agreement.

NOW, THEREFORE, for and in consideration of the foregoing and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, TBT, FFIN, the Proxy Holder and the Shareholders undertake, promise, covenant and agree with each other as follows:

AGREEMENT

1.    Each Shareholder, being the registered owner or beneficial owner of the number of shares of Common Stock set forth below the Shareholder’s name on the signature pages hereto (for each such Shareholder, the “Shares”), will vote, direct to vote, or act by consent with respect to:

(clauses (a), (b) and (c), collectively, the “Proxy Shares”), in favor of approval of the Merger Agreement, the Merger and any other transactions contemplated by the Merger Agreement.

2.    If TBT conducts a meeting of or otherwise seeks approval of its shareholders with respect to any Acquisition Proposal or any other matter that may contradict this Agreement or the Merger Agreement or may prevent FFIN or TBT from completing the Merger, then the Shareholders will vote the Proxy Shares against the approval of the Acquisition Proposal or otherwise act in the manner most favorable to completing the Merger and the transactions contemplated by the Merger Agreement.

3.    Each Shareholder shall not invite or seek any Acquisition Proposal, support (or publicly suggest that anyone else should support) any Acquisition Proposal that may be made, or ask the TBT Board to consider, support or seek any Acquisition Proposal or otherwise take any action designed to make any Acquisition Proposal more likely. None of the Shareholders shall meet or otherwise communicate with any Person that makes or is considering making an Acquisition Proposal or any representative of such Person after becoming aware that the Person has made or is considering making an Acquisition Proposal. Each Shareholder shall promptly advise TBT of each contact the Shareholder or any of the Shareholder’s representatives may receive from any Person relating to any Acquisition Proposal or otherwise indicating that any Person may wish to participate or engage in any transaction arising out of any Acquisition Proposal and will provide TBT with all information FFIN requests that is available to the Shareholder regarding any such Acquisition Proposal or possible Acquisition Proposal. Each Shareholder will not make any claim or join in any litigation alleging that the TBT Board is required to consider, endorse or support any Acquisition Proposal or to invite or seek any Acquisition Proposal. Each Shareholder shall not take any other action that is reasonably likely to make consummation of the Merger less likely or to impair FFIN’s ability to exercise any of the rights granted by the Merger Agreement.

4.    Each Shareholder, severally, but not jointly, represents and warrants to FFIN that:

B-3

5.    In order to better effect the provisions of Sections 1 and 2 of this Agreement, each Shareholder hereby revokes any previously executed proxies and hereby constitutes and appoints Proxy Holder, with full power of substitution, his true and lawful proxy and attorney-in-fact to vote at any meeting of the shareholders of TBT all of the Proxy Shares in favor of the approval of the Merger Agreement, the Merger and any other transactions contemplated by the Merger Agreement, with such modifications to the Merger Agreement as the parties thereto may make; provided, however, that this proxy will not apply with respect to any vote on approval of the Merger Agreement if the Merger Agreement is modified so as to (a) reduce the amount of consideration or the form of consideration to be received by the Shareholder or (b) materially alter the tax consequences of the receipt thereof under the Merger Agreement in its present form. This proxy shall be limited strictly and solely to the power and authority to vote the Proxy Shares in the manner and for the purpose set forth in Sections 1 and 2 of this Agreement and shall not extend to any other matters.

B-4

6.    Each Shareholder hereby covenants and agrees that until this Agreement is terminated in accordance with its terms, each Shareholder will not, and will not agree to, without the consent of FFIN, directly or indirectly, sell, transfer, assign, pledge, encumber, hypothecate, cause to be redeemed or otherwise dispose of (any such transaction, a “Transfer”) any of the Shares or grant any proxy or interest in or with respect to any Shares or deposit any such Shares into a voting trust or enter into another voting agreement or arrangement with respect to such Shares except as contemplated by this Agreement. Any attempted Transfer of Shares or any interest therein in violation of this Section shall be null and void. This Section shall not prohibit a Transfer of the Shares to any member of Shareholder’s immediate family, to another Shareholder, to a trust for the benefit of Shareholder or any member of Shareholder’s immediate family, or upon the death of Shareholder; provided, that a Transfer referred to in this sentence shall be permitted only if, as a precondition to such Transfer, the transferee agrees in a writing, reasonably satisfactory in form and substance to FFIN and TBT, to be bound by all of the terms of this Agreement.

7.    Proxy Holder, by his execution below, agrees to (a) vote all of the Shareholders’ Proxy Shares at any meeting of the shareholders of TBT, in favor of the approval of the Merger Agreement, the Merger and any other transactions contemplated by the Merger Agreement, with such modifications to the Merger Agreement as the parties thereto may make; provided, however, that this proxy will not apply with respect to any vote on approval of the Merger Agreement if the Merger Agreement is modified so as to (i) reduce the amount of consideration or the form of consideration to be received by the Shareholder or (ii) materially alter the tax consequences of the receipt thereof under the Merger Agreement in its present form, and (b) in the event of an Acquisition Proposal, to vote all of the Shareholders’ Proxy Shares at any meeting of the shareholders of TBT, against the approval of the Acquisition Proposal or otherwise act in the manner most favorable to completing the Merger and the transactions contemplated by the Merger Agreement.

8.    Each Shareholder acknowledges that FFIN and TBT are relying on this Agreement in incurring expenses in connection with FFIN’s review of TBT and the Bank’s business, in FFIN’s preparation, with TBT’s cooperation, of a proxy statement and Registration Statement on Form S-4, in FFIN’s proceeding with the filing of applications for regulatory approvals, and in their undertaking other actions necessary for completing the Merger and that THE PROXY GRANTED HEREBY IS COUPLED WITH AN INTEREST AND IS IRREVOCABLE TO THE FULL EXTENT PERMITTED BY APPLICABLE LAW, INCLUDING TO THE EXTENT APPLICABLE, SECTION 21.369 OF THE TBOC. The Shareholders and TBT acknowledge that the performance of this Agreement is intended to benefit FFIN.

9.    This Agreement shall remain in effect until the earliest to occur of (a) the termination of the Merger Agreement, as it may be amended or extended from time to time, pursuant to the terms and conditions contained therein, (b) completion of the transactions contemplated by the Merger Agreement, or (c) one (1) year after the date of this Agreement.

10.    Proxy Holder may, in his sole discretion, appoint a substitute proxy to act as Proxy Holder under this Agreement; provided, that any substitute proxy shall agree in writing to be bound by the terms and conditions of this Agreement. In the event of the death, disability or incapacity of Proxy Holder, FFIN, in its sole discretion, may appoint a substitute proxy to act as Proxy Holder under this Agreement.

B-5

11.    The vote of the Proxy Holder will control in any conflict between his vote of the Proxy Shares and a vote by the substitute proxy holder or the Shareholders of the Proxy Shares, and TBT agrees to recognize the vote of the Proxy Holder instead of the vote of substitute proxy holder or the Shareholders if the substitute proxy holder or the Shareholders do not vote in accordance with Sections 1 and 2 of this Agreement.

12.    This Agreement may not be amended, modified, altered or supplemented with respect to a particular Shareholder except upon the execution and delivery of a written agreement executed by FFIN, TBT, Proxy Holder and that Shareholder. Any such amendment, modification, alteration or supplement shall only apply to the Shareholder(s) executing such written agreement and this Agreement will remain in full force and effect with respect to Shareholders who do not execute such written agreement.

13.    For the convenience of the parties hereto, this Agreement may be signed in multiple counterparts, each of which will be deemed an original, and all counterparts hereof so signed by the parties hereto, whether or not such counterpart will bear the execution of each of the parties hereto, will be deemed to be, and is to be construed as, one and the same Agreement. An email or electronic scan in “PDF” format of a signed counterpart of this Agreement will be sufficient to bind the party or parties whose signature(s) appear thereon.

14.    This Agreement, the Merger Agreement, the Director Support Agreements and the other agreements, documents, schedules and instruments signed and delivered by the parties to each other at the Closing are the full understanding of the parties, a complete allocation of risks between them and a complete and exclusive statement of the terms and conditions of their agreement relating to the subject matter hereof and supersede any and all prior agreements, whether written or oral, that may exist between the parties with respect thereto.

15.    Any and all notices, requests, instructions and other communications required or permitted to be given under this Agreement after the date of this Agreement by any party hereto to any other party may be delivered personally or by nationally recognized overnight courier service or sent by mail or (except in the case of payments) by email or facsimile, at the respective addresses or transmission numbers set forth below and is deemed delivered (a) in the case of personal delivery, email or facsimile, when received; (b) in the case of mail, upon the earlier of actual receipt or five (5) Business Days after deposit in the United States Postal Service, first class certified or registered mail, postage prepaid, return receipt requested; and (c) in the case of an overnight courier service, one (1) Business Day after delivery to such courier service with instructions for overnight delivery.

16.    THIS AGREEMENT IS TO BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS, WITHOUT REGARD FOR THE PROVISIONS THEREOF REGARDING CHOICE OF LAW THAT WOULD APPLY THE LAW OF A DIFFERENT JURISDICTION. VENUE FOR ANY CAUSE OF ACTION BETWEEN THE PARTIES TO THIS AGREEMENT WILL LIE IN ▇▇▇▇▇▇ COUNTY, TEXAS. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH SUCH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY SUIT, ACTION OR OTHER PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT: (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR

B-7

OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ANY ACTION, SUIT OR PROCEEDING, SEEK TO ENFORCE THE FOREGOING WAIVER, (B) EACH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) EACH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) EACH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 16.

17.    All of the terms, covenants, representations, warranties and conditions of this Agreement are binding upon, and inure to the benefit of and are enforceable by, the parties and their respective successors, representatives and permitted assigns. No party to this Agreement may assign this Agreement, by operation of law or otherwise, in whole or in part, without the prior written consent of the other parties, and any purported assignment made or attempted in violation of this Section shall be null and void. Nothing contained in this Agreement, express or implied, is intended to confer upon any Persons, other than the parties hereto or their respective successors, any rights, remedies, obligations, or liabilities under or by reason of this Agreement.

18.    If any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws, then (a) this Agreement is to be construed and enforced as if such illegal, invalid or unenforceable provision were not a part hereof; (b) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by such illegal, invalid or unenforceable provision or by its severance from this Agreement; and (c) there will be added automatically as a part of this Agreement a provision mutually agreed to which is similar in terms to such illegal, invalid or unenforceable provision as may be possible and still be legal, valid and enforceable.

19.    Each of the parties hereto acknowledges that the other parties would be irreparably damaged and would not have an adequate remedy at law for money damages if any of the covenants contained in this Agreement were not performed in accordance with its terms or otherwise were materially breached. Each of the parties hereto therefore agrees that, without the necessity of proving actual damages or posting bond or other security, the other party will be entitled to temporary and/or permanent injunction or injunctions which a court of competent jurisdiction concludes is justified to prevent breaches of such performance and to specific enforcement of such covenants in addition to any other remedy to which they may be entitled, at law or in equity.

EXHIBIT C

FORM OF DIRECTOR SUPPORT AGREEMENT

This DIRECTOR SUPPORT AGREEMENT (the “Agreement”) is made and entered into as of September 19, 2019, by and between First Financial Bankshares, Inc., a Texas corporation and registered bank holding company under the Bank Holding Company Act of 1956, as amended (the “BHCA”), with its principal offices in Abilene, Texas (“FFIN”), and [                    ], an individual resident of the State of Texas (“Director”). Terms with their initial letters capitalized and not otherwise defined herein have the meanings given to them in the Merger Agreement (as defined below).

RECITALS

WHEREAS, FFIN, Brazos Merger Sub, Inc., a Texas corporation and wholly owned subsidiary of FFIN (“Merger Sub”), and TB&T Bancshares, Inc., a Texas corporation and registered bank holding company under the BHCA (“TBT”), have entered into an Agreement and Plan of Reorganization, dated as of the date hereof (the “Merger Agreement”), providing for FFIN’s acquisition of TBT through the merger of Merger Sub with and into TBT, with TBT surviving as a wholly owned subsidiary of FFIN (the “Merger”); and

WHEREAS, as a condition and inducement to FFIN’s willingness to enter into the Merger Agreement, FFIN and Director have agreed to enter into this Agreement.

NOW, THEREFORE, in consideration of the premises and mutual covenants contained herein and in the Merger Agreement intending to be legally bound hereby, FFIN and Director agree as follows;

AGREEMENT

1.    Director Support. Director agrees to use his or her good faith efforts to refrain from harming the goodwill of TBT, any Subsidiary of TBT (“TBT Subsidiary”), FFIN or any Subsidiary of FFIN, and their respective customer, client and vendor relationships. During the term of this Agreement, Director agrees to consider utilizing First Financial Bank, National Association, a national association with its principal office in Abilene, Texas and wholly owned subsidiary of FFIN, when obtaining banking products or services for his or her personal or business needs.

2.    Director Covenants.

(a)    Director acknowledges that he or she has received substantial, valuable consideration, including confidential trade secret and proprietary information relating to the identity and special needs of current and prospective customers of TBT or any TBT Subsidiary, TBT’s and any TBT Subsidiary’s current and prospective services, TBT’s and any TBT Subsidiary’s business projections and market studies, TBT’s and any TBT Subsidiary’s business plans and strategies, TBT’s and any TBT Subsidiary’s studies, and information concerning special services unique to TBT or any TBT Subsidiary. Director further acknowledges and agrees that this consideration constitutes fair and adequate consideration for the execution of the non-solicitation and non-competition restrictions set forth below. Accordingly, other than in any capacity for or on behalf of FFIN or any Subsidiary of FFIN, Director agrees that Director will not, directly or indirectly, individually or as an employee, partner, officer, director or shareholder or in any other capacity whatsoever:

i.    solicit the business of any person or entity who is a customer of TBT or any TBT Subsidiary as of the date of this Agreement or as of the Closing Date on behalf of any other insured depository institution for the purpose of providing financial services to such person or entity;

ii.    acquire any interest in (directly or indirectly), charter, operate or enter into any franchise or other management agreement with any insured depository institution that has a location within a 35 mile radius of any location of TBT or any TBT Subsidiary (the “Noncompete Area”) (but notwithstanding the foregoing, Director may (1) acquire an ownership interest in any publicly-traded depository institution, so long as that ownership interest does not exceed 1% of the total number of shares outstanding of that depository institution, and (2) invest in an existing mutual fund that invests, directly or indirectly, in such insured depository institutions);

iii.    from and after the Effective Time, serve as an officer, director, employee, agent or consultant to any insured depository institution that has a location within the Noncompete Area;

iv.    establish or operate a branch or other office of an insured depository institution within the Noncompete Area; or

v.    recruit, hire, assist others in recruiting or hiring, discuss employment with, or refer others concerning employment, any person who is, or within the 12 months preceding the Closing Date was, an employee of TBT or any TBT Subsidiary; but nothing in this Section 2(a)(v) applies to employment other than in financial services.

Director may not avoid the purpose and intent of this Section 2(a) by engaging in conduct within the Noncompete Area from a remote location through means such as telecommunications, written correspondence, computer generated or assisted communications, or other similar methods.

(b)    If any court of competent jurisdiction should determine that the terms of this Section 2 are too broad in terms of time, geographic area, lines of commerce or otherwise, that court is to modify and revise any such terms so that they comply with applicable law.

(c)    Director agrees that (i) this Agreement is entered into in connection with the sale to FFIN of TBT and The Bank & Trust of ▇▇▇▇▇/College Station, a Texas banking association with its principal place of business in Bryan, Texas (the “Bank”), (ii) Director is receiving valuable consideration for this Agreement, (iii) the restrictions imposed upon Director by this Agreement are essential and necessary to ensure FFIN acquires the goodwill of the TBT and the Bank, and (iv) all the restrictions (including particularly the time and geographical limitations) set forth in this Agreement are fair and reasonable.

3.    Early Resolution Conference. This Agreement is understood to be clear and enforceable as written and is executed by both parties on that basis. However, should Director later challenge any provision as unclear, unenforceable, or inapplicable to any competitive activity that Director intends to engage in, Director will first notify FFIN in writing and meet with a FFIN representative and a neutral mediator (if FFIN elects to retain one at its expense) to discuss resolution of any disputes between the parties. Director will provide this notice at least twenty-one (21) days before Director engages in any activity on behalf of a competing business or engages in other activity that could foreseeably fall

C-3

within a questioned restriction. If Director fails to comply with this requirement, Director waives his right to challenge the reasonable scope, clarity, applicability or enforceability of this Agreement and its restrictions at a later time.

4.    Termination. This Agreement and all obligations hereunder will terminate on the earlier of (a) the date the Merger Agreement is terminated pursuant to Section 9.01 of the Merger Agreement or (b) the date that is twenty-four (24) months after the Closing Date.

5.    Waiver, Amendment and Modification. Any party may unilaterally waive a right which is solely applicable to it. Such action will be evidenced by a signed written notice. No failure to exercise nor any delay in exercising any right, power or privilege hereunder by any party hereto will operate as a waiver thereof. No single or partial exercise of any right, power or privilege hereunder will 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 will 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. This Agreement may be amended, modified or supplemented only by an instrument in writing executed by each of the parties hereto.

6.    Governing Law. THIS AGREEMENT IS TO BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF TEXAS WITHOUT REGARD FOR THE PROVISIONS THEREOF REGARDING CHOICE OF LAW THAT WOULD APPLY THE LAW OF A DIFFERENT JURISDICTION. VENUE FOR ANY CAUSE OF ACTION BETWEEN THE PARTIES TO THIS AGREEMENT WILL LIE IN ▇▇▇▇▇▇ COUNTY, TEXAS. EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES AND, THEREFORE, EACH SUCH PARTY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LEGAL ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY TO THIS AGREEMENT CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT SEEK TO ENFORCE THE FOREGOING WAIVER IN THE EVENT OF A LEGAL ACTION, (B) SUCH PARTY HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (C) SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (D) SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 6.

7.    Binding Effect; Assignment. All of the terms, covenants, representations, warranties and conditions of this Agreement are binding upon, and inure to the benefit of and are enforceable by, the parties and their respective successors, representatives and permitted assigns. No party to this Agreement may assign this Agreement, by operation of law or otherwise, in whole or in part, without the prior written consent of the other parties, and any purported assignment made or attempted in violation of this Section shall be null and void.

C-4

8.    No Third Party Beneficiaries. Nothing contained in this Agreement, express or implied, is intended to confer upon any Persons, other than the parties hereto or their respective successors, any rights, remedies, obligations, or liabilities under or by reason of this Agreement.

9.    Severability. If any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws, then (a) this Agreement is to be construed and enforced as if such illegal, invalid or unenforceable provision were not a part hereof; (b) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by such illegal, invalid or unenforceable provision or by its severance from this Agreement; and (c) there will be added automatically as a part of this Agreement a provision mutually agreed to which is similar in terms to such illegal, invalid or unenforceable provision as may be possible and still be legal, valid and enforceable.

10.    Specific Performance. Each of the parties hereto acknowledges that the other parties would be irreparably damaged and would not have an adequate remedy at law for money damages if any of the covenants contained in this Agreement were not performed in accordance with its terms or otherwise were materially breached. Each of the parties hereto therefore agrees that, without the necessity of proving actual damages or posting bond or other security, the other party will be entitled to temporary and/or permanent injunction or injunctions which a court of competent jurisdiction concludes is justified to prevent breaches of such performance and to specific enforcement of such covenants in addition to any other remedy to which they may be entitled, at law or in equity.

11.    Entire Agreement. This Agreement, the Merger Agreement, the Voting Agreement and the other agreements, documents, schedules and instruments signed and delivered by the parties to each other at the Closing are the full understanding of the parties, a complete allocation of risks between them and a complete and exclusive statement of the terms and conditions of their agreement relating to the subject matter hereof and supersede any and all prior agreements, whether written or oral, that may exist between the parties with respect thereto.

12.    Rules of Construction. Descriptive headings as to the contents of particular sections are for convenience only and do not control or affect the meaning, construction or interpretation of this Agreement or any particular section.
