ARTICLE III

CONSIDERATION; EXCHANGE PROCEDURES

3.01. Consideration. At the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of TRBI Stock or Merger Sub Stock, each share of TRBI Common Stock outstanding immediately prior to the Effective Time, except for Dissenting Shares for which the right to dissent has been perfected, has not been withdrawn and which has not otherwise been lost, will be converted into an amount in cash, without interest, equal to $38.90 (the “Per Share Amount”); provided that

each share of TRBI Common Stock beneficially owned by BBVA (other than shares held in a trust, fiduciary, or nominee capacity or as a result of debts previously contracted) or held in TRBI’s treasury will be canceled and no amount of cash or other consideration will be paid in exchange therefor.

3.02. Cancellation of Shares; Stock Transfers. At the Effective Time, the shares of TRBI Common Stock will no longer be outstanding and will automatically be canceled and will cease to exist. Certificates that represented TRBI Common Stock before the Effective Time will be deemed for all purposes to represent only, and holders of TRBI Common Stock will have no rights as shareholders of TRBI other than, the right to receive, without interest, (A) any then unpaid dividend or other distribution with respect to such TRBI Common Stock having a record date before the Effective Time and (B) the cash consideration provided for in Section 3.01. After the Effective Time, there will be no transfers of shares of TRBI Common Stock on the stock transfer books of the TRBI or the Surviving Corporation, and shares of TRBI Common Stock presented to the Surviving Corporation or BBVA for any reason will be canceled and exchanged in accordance with this Article III.

3.03. Merger Sub Stock. Each share of Merger Sub Stock outstanding immediately prior to the Effective Time shall be converted into one validly issued, fully paid and nonassessable share of common stock, no par value, of the Surviving Corporation.

3.04. Exchange Procedures. (a) Immediately prior to the Effective Time, BBVA will deposit with a depository or trust institution of recognized standing selected by it and reasonably satisfactory to TRBI (in such capacity, the “Exchange Agent”), for the benefit of the holders of certificates formerly representing shares of TRBI Common Stock (“Old Certificates”), cash payable pursuant to Section 3.01 (the “Exchange Fund”).

(b) As soon as practicable after the Effective Time, but in no event later than five (5) business days thereafter, BBVA will cause the Exchange Agent to send to each person who was a record holder of TRBI Common Stock immediately before the Effective Time transmittal materials for exchanging Old Certificates. If practicable, BBVA shall make available such transmittal materials to TRBI prior to the Effective Time. Upon surrender of an Old Certificate for cancellation to the Exchange Agent together with the transmittal materials, duly executed, and such other documents as the Exchange Agent may reasonably require (including customary indemnity if any of such certificates are lost, stolen, or destroyed), the holder of such Old Certificate shall be entitled to receive in exchange therefor a check representing the cash payable pursuant to Section 3.01, which shall be paid as soon as reasonably practicable, and in any event within five (5) business days of the later of the receipt of such materials or the Effective Time. No interest will be paid on any such cash or other consideration deliverable pursuant to this Article III upon surrender of Old Certificates. At the twelve-month anniversary of the Effective Time, any portion of the Exchange

Fund remaining in the possession of the Exchange Agent (together with any dividends or earnings in respect thereof) shall be returned to BBVA. Any former holders of TRBI Common Stock who have not theretofore exchanged their Old Certificates for the Per Share Amount pursuant to this Article III shall thereafter be entitled only to look exclusively to BBVA, and only as general unsecured creditors thereof, for payment of any Per Share Amount which they are entitled to receive upon exchange of their Old Certificates pursuant to this Article III, without any interest thereon.

(c) None of BBVA, Merger Sub, TRBI and the Exchange Agent will be liable to any former holder of TRBI Common Stock for any cash from the Exchange Fund properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

3.05. Stock Options. At the Effective Time, all outstanding and unexercised options to purchase shares of TRBI Common Stock (each, a “TRBI Stock Option”), whether vested or unvested, will cease to represent an option to purchase TRBI Common Stock and will be converted automatically into the right to receive in cash, without interest, as soon as reasonably practicable following the Effective Time, an amount equal to the product of (i) the excess of the Per Share Amount over the option exercise price and (ii) the number of shares of TRBI Common Stock subject to the option. Before the Effective Time, TRBI, or its Board of Directors or an appropriate committee thereof, shall take all action necessary (to the extent permissible under the provisions thereof and applicable law) on its part to give effect to the provisions of this Section 3.05 and shall take such other actions reasonably requested by BBVA to give effect to this Section 3.05.

3.06. Dissenting Shares. Notwithstanding any other provision contained in this Agreement, shares of TRBI Common Stock that are issued and outstanding as of the Effective Time and that are held by a shareholder who has not voted such shares in favor of the Merger and who has otherwise taken all of the steps required by Article 5.12 of the TBCA to properly exercise and perfect such shareholder’s dissenter’s rights (any such shares being referred to herein as “Dissenting Shares”) shall be deemed to have ceased to represent any interest in the Surviving Corporation as of the Effective Time and shall be entitled to those rights and remedies set forth in Articles 5.11, 5.12 and 5.13 of the TBCA; provided, however, that in the event that a shareholder of TRBI fails to perfect, withdraws or otherwise loses any such right or remedy granted by the TBCA, the shares of TRBI Common Stock held by such shareholder shall be converted into and represent only the right to receive the Per Share Amount specified in this Agreement. TRBI shall give BBVA (a) prompt notice of any notice or demand for appraisal or payment for shares of TRBI Common Stock received by TRBI and (b) the opportunity to participate in and direct all negotiations and proceedings with respect to any such demands or notices. TRBI shall not, without the prior written consent of BBVA, make any payment with respect to, or settle, offer to settle or otherwise negotiate any such demands.

ARTICLE IV

Neither it nor any of its Subsidiaries has engaged in a transaction with respect to any of its Benefit Arrangements that, assuming the taxable period of such transaction expired as of the date hereof, could subject it or any of its Subsidiaries to a tax or penalty imposed by either Section 4975 of the Code or Section 502(i) of ERISA. Neither it nor any of its Subsidiaries has incurred or reasonably expects to incur a tax or penalty imposed by Section 4980F of the Code or Section 502 of ERISA or any liability under Section 4071 of ERISA.

(3) No liability under Subtitle C or D of Title IV of ERISA has been or is reasonably expected to be incurred by it or any of its Subsidiaries with respect to any ongoing, frozen or terminated “single-employer plan”, within the meaning of Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them, or the single-employer plan of any entity which is considered one employer with it under Section 4001 of ERISA or Section 414 of the Code (an “ERISA Affiliate”). None of it, any of its Subsidiaries or any of its ERISA Affiliates has contributed to a “multiemployer plan”, within the meaning of Section 3(37) of ERISA, at any time within the last six years.

Neither any Pension Plan nor any single-employer plan of any of its ERISA Affiliates has been required to file information pursuant to Section 4010 of ERISA for the current or most recently completed plan year. It is not reasonably anticipated that required minimum contributions to any Pension Plan under Section 412 of the Code will be increased by application of Section 412(l) of the Code. Neither it nor any of its Subsidiaries has provided, or is required to provide, security to any of its Pension Plans or to any single-employer plan of any of its ERISA Affiliates pursuant to Section 401(a)(29) of the Code.

(6) Neither it nor any of its Subsidiaries has any obligations for retiree health and life benefits under any Benefit Arrangement, Employment Agreement or collective bargaining agreement.

(7) There has been no amendment to, announcement by it or any of its subsidiaries relating to, or change in employee participation or coverage under, any Benefit Arrangement which would increase the expense of maintaining such Benefit Arrangement above the level of the expense incurred therefor for the most recent fiscal year. Neither its execution of this Agreement, the performance of its obligations hereunder, the consummation of the transactions contemplated hereby, the termination of the employment of any of its employees within a specified time of the Effective Time nor shareholder approval of the transactions covered by this Agreement, will (A) limit its right, in its sole discretion, to administer or amend in any respect or terminate any of its Benefit Arrangements or any related trust, (B) entitle any of its employees or any employees of its Subsidiaries to severance pay or any increase in severance pay, or (C) accelerate the time of payment or vesting or trigger any payment or funding (through a grantor trust or otherwise) of compensation or benefits under, increase the amount payable or trigger any other material obligation pursuant to, any of its Benefit Arrangements or Employment Agreements. Without limiting the foregoing, as a result of the consummation of the transactions contemplated hereby (including as a result of the termination of the employment of any of its employees within a specified time of the Effective Time) neither it nor any of its Subsidiaries will be obligated to make a payment to an individual that would be a “parachute payment” to a “disqualified individual” as those terms are defined in Section 280G of the Code, without regard to whether such payment is reasonable compensation for personal services performed or to be performed in the future.

(8) All TRBI Stock Options that have been granted under the TRBI Stock Plans were granted (without giving effect to any amendment

It has made provision in accordance with GAAP, in the financial statements included in the Regulatory Filings filed before the date hereof, for all Taxes that accrued on or before the end of the most recent period covered by its Regulatory Filings filed before the date hereof. No Liens for Taxes exist with respect to any of its assets or properties or those of its Subsidiaries, except for statutory Liens for Taxes not yet due and payable or that are being contested in good faith and reserved for in accordance with GAAP. Neither it nor any of its Subsidiaries has been a party to any distribution occurring during the two-year period prior to the date of this Agreement in which the parties to such distribution treated the distribution as one to which Section 355 of the Code applied, except for distributions occurring among members of the same group of affiliated corporations filing a consolidated federal income tax return. Neither it nor any of its Subsidiaries has been a party to any “reportable transaction” within the meaning of Treasury Regulations Section 1.6011-4.

ARTICLE VI

COVENANTS

6.01. Reasonable Best Efforts. (a) Subject to the terms and conditions of this Agreement, BBVA and TRBI will each use reasonable best efforts to take, or cause to be taken, in good faith, all actions, and to do, or cause to be done, all things necessary, proper or desirable, or advisable under applicable laws, so as to permit consummation of the Merger as promptly as practicable and otherwise to enable consummation of the transactions contemplated hereby, and each will cooperate fully with, and furnish information to, the other party to that end.

(b) Without limiting the generality of Section 6.01(a), TRBI agrees to use its reasonable best efforts to obtain the consent or approval of all persons party to a Contract with TRBI or any of its Subsidiaries, to the extent such consent or approval is required in order to consummate the Merger or for the Surviving Corporation to receive the benefit of such Contract.

6.02. Shareholder Approval. The TRBI Board will submit to its shareholders the plan of merger contained in this Agreement and any other matters required to be approved or adopted by shareholders in order to carry out the intentions of this Agreement. In furtherance of that obligation, TRBI will take, in accordance with applicable law, applicable NASDAQ National Market System rules, the rules of any other relevant exchange and its Constituent Documents, all action necessary to convene a meeting of its shareholders (including any adjournment or postponement, the “TRBI Meeting”), as promptly as practicable, to consider and vote upon approval of the plan of merger as well as any other such matters. Except as specifically provided in the second succeeding sentence below, the TRBI Board will use all reasonable best efforts to obtain from its shareholders a vote approving the plan of merger contained in this Agreement, including providing an unqualified recommendation that its shareholders vote in favor of the Merger. Unless the Agreement has previously been terminated pursuant to Article VIII, TRBI shall be obligated to hold the TRBI Meeting notwithstanding any Acquisition Proposal or other event or circumstance, and TRBI agrees that it will not submit any Acquisition Proposal to its shareholders for a vote. However, notwithstanding the foregoing or anything herein to the contrary, if the TRBI Board, after consultation with (and based on the advice of) counsel, determines in good faith that, because of the receipt by TRBI of an Acquisition Proposal that the TRBI Board concludes in good faith constitutes a Superior Proposal, it would more likely than not result in a violation of its fiduciary duties under applicable law to continue to recommend the plan of merger set forth in this Agreement, then, in submitting the plan of merger to the TRBI Meeting, the TRBI Board may submit the plan of merger to its shareholders without recommendation (although the resolutions adopting this Agreement as of the date hereof may not be rescinded or amended), in which event the TRBI Board may communicate the basis for its lack of a recommendation to the shareholders in the Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law; provided that the TRBI Board may not take any actions under this sentence until after giving BBVA at least 10 business days to respond to such Acquisition Proposal (and after giving BBVA notice of the latest material terms, conditions and identity of the third party in the Acquisition Proposal) and then taking into account any amendment or modification to this Agreement proposed by BBVA.

6.03. Proxy Statement. (a) TRBI will prepare a proxy statement for the TRBI Meeting (the “Proxy Statement”) and all related documents. Each party will cooperate, and will cause its Subsidiaries to cooperate, with the other party, its counsel and its accountants, in the preparation of the Proxy Statement and any amendment or supplement thereto, the solicitation of proxies and preparation for the TRBI Meeting, and, provided that BBVA and its Subsidiaries have cooperated in such manner as to permit it to do so,

TRBI agrees to file the Proxy Statement and any amendment or supplement thereto with the SEC within the time required to permit the TRBI Meeting to be held as promptly as reasonably practicable and the Closing to occur in a timely manner. Each party shall cooperate and provide the other party with a reasonable opportunity to review and comment on any amendment to the Proxy Statement prior to filing it with the SEC.

(b) Each of BBVA and TRBI agrees, as to itself and its Subsidiaries, that none of the information supplied or to be supplied by it for inclusion or incorporation by reference in the Proxy Statement and any amendment or supplement thereto will, at the date of mailing to shareholders and at the time of the TRBI Meeting, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which such statement was made, not misleading. BBVA and TRBI each further agrees that if it becomes aware that any information furnished by it would cause any of the statements in the Proxy Statement to be false or misleading with respect to any material fact, or to omit to state any material fact necessary to make the statements therein not false or misleading, to promptly inform the other party thereof and to take appropriate steps to correct the Proxy Statement.

6.04. Press Releases. BBVA and TRBI will consult with each other before issuing any press release, written employee communication or other written shareholder communication with respect to the Merger or this Agreement and will not issue any such communication or make any such public statement without the prior consent of the other party, which will not be unreasonably withheld or delayed; provided that a party may, without the prior consent of the other party (but after prior consultation, to the extent practicable in the circumstances), issue such communication or make such public statement as may be required by applicable law or securities exchange rules, provided, however, that such party shall immediately inform the other party of the issuance of such public communication or the making of such public statement. BBVA and TRBI will cooperate to develop all public communications and make appropriate members of management available at presentations related to the transactions contemplated hereby as reasonably requested by the other party.

6.05. Access; Information. (a) TRBI agrees that upon reasonable notice and subject to applicable laws relating to the exchange of information, it will (and will cause its Subsidiaries to) afford BBVA, and BBVA’s officers, employees, counsel, accountants and other authorized Representatives, such access during normal business hours to TRBI’s books, records (including, without limitation, Tax Returns and work papers of independent auditors), properties, personnel and to such other information as BBVA may reasonably request and TRBI will furnish promptly to BBVA (1) a copy of each report, schedule and other document filed by it pursuant to the requirements of federal or state securities or banking laws, and (2) all other information concerning the business, properties and personnel of it as BBVA may reasonably request. BBVA will use its best efforts to exercise such right of access in such manner as to not disrupt the normal

business activities of TRBI. Notwithstanding the foregoing, TRBI shall not be required to afford access or disclose information that would cause TRBI to forfeit the right to assert the attorney-client privilege in any pending or threatened proceeding.

(b) A will hold any information which is nonpublic and confidential to the extent required by, and in accordance with, the Confidentiality Agreement between BBVA and TRBI, dated May 12, 2006 (the “Confidentiality Agreement”).

(c) No investigation by BBVA of the business and affairs of TRBI, pursuant to this Section 6.05 or otherwise, will affect or be deemed to modify or waive any representation, warranty, covenant or agreement in this Agreement, or the conditions to BBVA’s obligation to consummate the transactions contemplated hereby.

6.06. Acquisition Proposals. (a) TRBI will not, and will cause its Subsidiaries and its and its Subsidiaries’ officers, directors, agents, advisors and affiliates not to, initiate, solicit, encourage or knowingly facilitate inquiries or proposals with respect to, or engage in any negotiations concerning, or provide any confidential or nonpublic information or data to, or have any discussions with, any person relating to, any Acquisition Proposal, provided that, in the event TRBI receives an unsolicited bona fide Acquisition Proposal, including from an Other Person (as defined below) after the execution of this Agreement, and the TRBI Board concludes in good faith that such Acquisition Proposal constitutes a Superior Proposal, TRBI may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished nonpublic information and participate in such negotiations or discussions to the extent that the TRBI Board concludes in good faith (and based on the advice of counsel) that failure to take such actions would more likely than not result in a violation of its fiduciary duties under applicable law; provided further, that prior to providing any nonpublic information permitted to be provided pursuant to the foregoing proviso, it shall have entered into a confidentiality agreement with such third party on terms no less favorable to it than the Confidentiality Agreement (without regard to any modification thereof pursuant hereto). TRBI will immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any persons other than BBVA (“Other Persons”) with respect to any Acquisition Proposal and will use its reasonable best efforts to enforce any confidentiality or similar agreement relating to an Acquisition Proposal. TRBI will promptly (within 24 hours) advise BBVA following receipt of any Acquisition Proposal and the substance thereof (including the identity of the person making such Acquisition Proposal), and will keep BBVA apprised of any related developments, discussions and negotiations (including the terms and conditions of the Acquisition Proposal) on a current basis.

(b) Nothing contained in this Agreement shall prevent TRBI or the TRBI Board from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act with respect to an Acquisition Proposal, provided that such Rules will in no

way eliminate or modify the effect that any action pursuant to such Rules would otherwise have under this Agreement.

6.07. Takeover Laws and Provisions. TRBI will not take any action that would cause the transactions contemplated hereby or by the Voting Agreements to be subject to requirements imposed by any Takeover Law and TRBI will take all reasonably necessary steps within its control to exempt (or ensure the continued exemption of) those transactions from, or if necessary and reasonable to do so, to challenge the validity or applicability of, any applicable Takeover Law, as now or hereafter in effect. TRBI will not take any action that would cause the transactions contemplated hereby and thereby not to comply with any Takeover Provisions and TRBI will take all necessary steps within its control to make those transactions comply with (or continue to comply with) any Takeover Provisions. BBVA will not purchase shares of TRBI Common Stock representing 5% or more of the outstanding shares of TRBI Common Stock.

6.08. Regulatory Applications; Third-Party Consents. (a) Each of BBVA and TRBI and their respective Subsidiaries will use all reasonable best efforts to prepare as promptly as possible all documentation, to effect all filings and to obtain all permits, consents, approvals and authorizations of all Governmental Authorities (the “Requisite Regulatory Approvals”) that are required to be effected or obtained by it, and of all other third parties from which it is required to obtain consents (the “Third-Party Consents”), necessary to consummate the transactions contemplated hereby and, and will make all necessary filings in respect of those Requisite Regulatory Approvals and Third-Party Consents for which it is responsible as soon as practicable. Each of BBVA and TRBI will have the right to review in advance, and to the extent practicable each will consult with the other, in each case subject to applicable laws relating to the exchange of information, with respect to all material written information submitted to any third party or any Governmental Authority in connection with the Requisite Regulatory Approvals and Third-Party Consents. In exercising the foregoing right, each of the parties will act reasonably and as promptly as practicable. Each party agrees that it will consult with the other party with respect to obtaining all material permits, consents, approvals and authorizations of all third parties and Governmental Authorities necessary or advisable to consummate the transactions contemplated hereby and each party will keep the other party appraised of the status of material matters relating to completion of the transactions contemplated hereby.

Each party will cooperate with the other party and will assist the other party as reasonably requested to permit the other party to obtain the Requisite Regulatory Approvals and Third-Party Consents to be obtained by the other party.

6.09. No Rights Triggered. TRBI shall take all reasonable steps necessary to ensure that the entering into of this Agreement and the Voting Agreements and the consummation of the transactions contemplated hereby and thereby, and any other action or combination of actions, or any other transactions contemplated hereby or thereby, do not and will not result in the grant of any Rights to any person (a) under TRBI’s Constituent Documents or (b) under any material Contract to which TRBI or any of its Subsidiaries is a party except, in each case, as Previously Disclosed or contemplated by this Agreement and the Voting Agreements.

6.10. Funds.

8.03. Termination Fee. (a) As a condition of BBVA and Merger Sub’s willingness, and in order to induce BBVA and Merger Sub, to enter into this Agreement, TRBI hereby agrees to pay to BBVA, and BBVA shall be entitled to payment of a fee of $85 million ($85,000,000) (less any payment made pursuant to the proviso in Section 9.05) if (each of the following being a “Fee Payment Event”) any of the following occur following the date hereof and prior to a Fee Termination Event, as hereafter defined:

(1) TRBI or any of its Subsidiaries, without having received BBVA’s prior written consent, shall have entered into an agreement to engage in an Acquisition Transaction with any person other than BBVA or any of its Subsidiaries (each an “BBVA Subsidiary”), or the TRBI Board shall have recommended that the shareholders of TRBI approve or accept any Acquisition Transaction with any person other than BBVA or an BBVA Subsidiary;

(2) Any person other than BBVA or any BBVA Subsidiary shall have acquired beneficial ownership or the right to acquire beneficial ownership of 25% or more of the outstanding shares of TRBI Common Stock;

(4) This Agreement is terminated (A) following an Acquisition Proposal or (B) pursuant to Section 8.01(e), in the event TRBI’s failure to comply with any provision of this Agreement has been the primary cause of the failure of the Effective Time to occur on or before such date, or (C) pursuant to Section 8.01(f), in the event TRBI’s failure to comply with any provision of this Agreement has been the primary cause of the denial of any approval referred to in such Section 8.01(f) and, within 18 months after any of the events described in (A), (B) or (C), an event described in Section 8.03(a)(1) or Section 8.03(a)(2) occurs.

(b) Any payment required to be made under Section 8.03(a) shall be payable within three business days following the Fee Payment Event. In any case such payment shall be made, without setoff, by wire transfer in immediately available funds, to an account specified by BBVA.

(c) TRBI acknowledges that the agreements contained in this Section 8.03 are an integral part of the transactions contemplated by this Agreement and are cumulative with, and not intended to limit, other remedies that may be available, and that, without these agreements, BBVA would not enter into this Agreement; accordingly, if TRBI fails promptly to pay any amount due pursuant to this Section 8.03, and, in order to obtain such payment, BBVA commences a suit which results in a judgment against TRBI for the payment set forth in this Section 8.03, TRBI shall reimburse BBVA’s costs and expenses (including reasonable attorneys’ fees) in connection with such suit, together with interest on any amount due pursuant to this Section 8.03 from the date such amount becomes payable until the date of such payment at the prime rate published in The Wall Street Journal in effect on the date such payment was required to be made.

(d) TRBI shall notify BBVA promptly in writing of the occurrence of any Fee Payment Event, it being understood that the giving of such notice by TRBI shall not be a condition to BBVA’s rights pursuant to this Section 8.03.

(e) For purposes hereof, a “Fee Termination Event” is any one of the following: (1) the Effective Time, or (2) the expiration of eighteen (18) months following termination of this Agreement.

9.07. Entire Understanding; No Third Party Beneficiaries. This Agreement and the Voting Agreements represent the entire understanding of BBVA and TRBI regarding the transactions contemplated hereby and supersede any and all other oral or written agreements previously made or purported to be made, other than the Confidentiality Agreement, which will survive the execution and delivery of this Agreement. No representation, warranty, inducement, promise, understanding or condition not set forth in this Agreement has been made or relied on by any party in entering into this Agreement. Except for Section 6.11, which is intended to benefit the Indemnified Parties to the extent stated, nothing expressed or implied in this Agreement is intended to confer any rights, remedies, obligations or liabilities upon any person other than BBVA, Merger Sub and TRBI.

9.08. Assignment. Neither this Agreement nor any of the rights, interests or obligations hereunder shall be assigned or delegated, in whole or in part (except by operation of law), by any of the parties hereto without the prior written consent of each other party hereto, except that BBVA and Merger Sub may assign or delegate in their sole discretion any or all of their rights, interests or obligations under this Agreement to any direct or indirect, wholly owned subsidiary of BBVA, but no such assignment shall relieve BBVA of any of its obligations hereunder. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of and be enforceable by, the parties hereto and their respective successors and assigns.

9.09. Waiver of Jury Trial. All of the parties hereto irrevocably waive any and all right to trial by jury in any legal proceeding arising out of or related to this Agreement or the transactions contemplated hereby.

9.10. Severability. If any provision of this Agreement or the application thereof to any person or circumstance is determined by a court of competent jurisdiction to be invalid, void or unenforceable, the remaining provisions, or the application of such provision to persons or circumstances other than those as to which it has been held

invalid or unenforceable, will remain in full force and effect and will in no way be affected, impaired or invalidated thereby, so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination, the parties will negotiate in good faith in an effort to agree upon a suitable and equitable substitute provision to effect the original intent of the parties.

9.11. Alternative Structure. Notwithstanding anything to the contrary contained in this Agreement or the Confidentiality Agreement, before the Effective Time, BBVA may revise the structure of the Merger or otherwise revise the method of effecting the Merger and related transactions, in a manner acceptable to TRBI, approval of or consent to which shall not be unreasonably withheld or delayed, provided that (1) such revision does not alter or change the kind or amount of consideration to be delivered to the shareholders of TRBI and the holders of TRBI Stock Options, (2) such revision does not adversely affect the tax consequences to the shareholders of TRBI, (3) such revised structure or method is reasonably capable of consummation without significant delay in relation to the structure contemplated herein, and (4) such revision does not otherwise cause any of the conditions set forth in Article VII not to be capable of being fulfilled (unless duly waived by the party entitled to the benefits thereof). This Agreement and any related documents will be appropriately amended in order to reflect any such revised structure or method.

IN WITNESS WHEREOF, the parties have caused this Agreement to be executed by their duly authorized officers as of the day and year first above written.
