(ii) each Outstanding Bank Share shall be converted into the right to receive cash in an amount equal to Ten Dollars and Twenty and One Half Cents ($10.205) (the “Purchase Price Per Share”), provided that there are no greater than 1,730,463 shares of Outstanding Bank Shares;

(iii) each Bank NQSO shall, ipso facto and without any action on the part of holders thereof, become and be converted into the right to receive the difference between the Purchase Price Per Share and Six Dollars and Thirty One Cents ($6.31) (the “NQSO Option Spread”), payable as provided herein and less any Tax withholding required under the Code or any provision of state or local law, and prior to the Effective Time, the Bank’s board of directors shall take such actions or make such determinations as may be required under the Bank’s stock option plan or plans, subject to the approval of Acquiror, to effect the provisions of this Agreement;

Section 3.2 Rights as Shareholders; Stock Transfers. At the Effective Time, the Bank Shareholders shall cease to be, and shall have no rights as, Bank Shareholders, other than to receive the Merger Consideration.

Upon proper surrender to the Paying Agent of a Certificate for exchange and cancellation, together with such properly completed and duly executed Transmittal Letter, the holder of such Certificates shall be entitled to receive in exchange therefore a check representing the amount of Merger Consideration that such holder is entitled to receive pursuant to this Article, and the Certificates so surrendered shall forthwith be cancelled.

(d) The Paying Agent shall deliver to each Bank Shareholder who has submitted a completed Transmittal Letter, accompanied by the related Certificates, the Merger Consideration, without interest, to which he or she is entitled to receive pursuant to the terms of this Agreement.

(e) Neither the Paying Agent nor any party hereto shall be liable to any former Bank Shareholder for any amount properly delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(f) Each of the Paying Agent, the Resulting Bank and Acquiror shall be entitled to deduct and withhold from the consideration otherwise payable to any Person pursuant to this Article such amounts as it is required to deduct and withhold with respect to the making of such payment under any Legal Requirement. If the Paying Agent, the Resulting Bank or Acquiror, as the case may be, so withholds amounts, such amounts shall be treated for all purposes of this Agreement as having been paid to the Bank Shareholders by the Paying Agent.

(g) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of the fact by the Person claiming such Certificate to be lost, stolen or destroyed and the posting by such person of a bond, in such reasonable amount as the Paying Agent or the Resulting Bank may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Paying Agent will issue, in exchange for such lost, stolen or destroyed Certificate, the appropriate amount of cash, as provided in this Article, to be paid in respect of Bank Stock represented by such Certificate.

(h) Any portion of the Merger Consideration that remains unclaimed by the Bank Shareholders on the six (6) month anniversary of the Effective Time shall be paid to Acquiror to be held for the benefit of holders of unsurrendered Certificates. Any Bank Shareholders who have not theretofore complied with this Article shall thereafter look only to Acquiror for payment of the Merger Consideration without any interest thereon.

(i) If a check representing Merger Consideration is to be issued in a name other than that in which the Certificate surrendered in exchange therefor is registered, it shall be a condition of the issuance thereof that the Certificate so surrendered shall be properly endorsed, accompanied by all documents required to evidence and effect such transfer and otherwise in proper form for transfer and that the Person requesting such payment shall pay to Acquiror any transfer or other taxes required by reason of the issuance of a check for Merger Consideration in any name other than that of the registered holder of the Certificate surrendered, or otherwise required, or shall establish to the satisfaction of Acquiror that such tax has been paid or is not payable.

(j) Immediately prior to the Effective Time, all outstanding Bank NQSOs and Bank ISOs shall become immediately exercisable and fully vested.

The payment of the NQSO Option Spreads and the ISO Option Spreads pursuant to this Article shall be delivered and paid in full satisfaction of all rights pertaining to the outstanding Bank NQSOs and Bank ISOs, respectively.

Section 3.4 Dissenting Shares. Notwithstanding anything in this Agreement to the contrary, the shares of Bank Stock that are issued and outstanding immediately prior to the Effective Time and that are held by Dissenting Shareholders (the “Dissenting Shares”) shall not be converted into or be exchangeable for the right to receive the Merger Consideration pursuant to the provisions of this Article, unless and until such holder shall have failed to perfect or shall have effectively withdrawn the holder’s right to appraisal and payment under the Arizona Statutes. If such holder shall have so failed to perfect or shall have effectively withdrawn or lost such right, such Bank Stock shall thereupon be deemed to have been converted into and to have become exchangeable for, as of the Effective Time, the right to receive the consideration described in this Article, without any interest thereon. The Bank agrees to give Acquiror notice of any written demands for appraisal or notices of dissent with respect to any Bank Stock pursuant to the Arizona Statutes, or any withdrawal of any such demand, and any other instruments served and received by the Bank, and Acquiror shall have the right to participate in all negotiations and proceedings with respect to any demands for appraisal made by any Dissenting Shareholders. Prior to the Effective Time, the Bank shall not, except with the prior written consent of Acquiror, make any payment with respect to, or offer to settle, any such demands.

The Bank hereby represents and warrants to Acquiror and AB&T that the following are true and correct as of the Agreement Date, and will be true and correct as of the Effective Date:

Section 4.1 Bank Organization. The Bank is an Arizona corporation that holds a banking permit and is validly existing and in good standing under the laws of the State of Arizona. The Bank has full power and authority, corporate and otherwise, to own, operate and lease its properties as presently owned, operated and leased, and to carry on its business as it is now being conducted, and is duly qualified to do business and is in good standing in each jurisdiction in which the nature of the business conducted or the properties or assets owned or leased by it makes such qualification necessary. Copies of the articles of incorporation and bylaws of the Bank and all amendments thereto are set forth on Schedule 4.1 and are complete and correct.

Section 4.2 Authorization; Enforceability.

(a) The Bank has the requisite power and authority to enter into and perform its obligations under this Agreement. The execution, delivery and performance of this Agreement by the Bank, and the consummation by it of its obligations under this Agreement, have been authorized by all necessary corporate action, subject to shareholder approval, and this Agreement constitutes a legal, valid and binding obligation of the Bank enforceable in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors’ rights generally and subject to general principles of equity.

(b) Except for ordinary corporate requirements, no “business combination,” “moratorium,” “control share” or other state anti-takeover statute or regulation or any provisions contained in the articles of incorporation or bylaws or similar organizational documents of the Bank: (i) prohibits or restricts the Bank’s ability to perform its obligations under this Agreement, or its ability to consummate the Contemplated Transactions; (ii) would have the effect of invalidating or voiding this Agreement, or any provision hereof; or (iii) would subject Acquiror or AB&T to any material impediment or condition in connection with the exercise of any of its rights under this Agreement. The board of directors of the Bank has unanimously approved the execution of, and performance by the Bank of its obligations under, this Agreement.

Section 4.3 No Conflict. Except as set forth on Schedule 4.3, neither the execution nor delivery of this Agreement nor the consummation or performance of any of the Contemplated Transactions will, directly or indirectly (with or without notice or lapse of time): (a) contravene, conflict with or result in a violation of any provision of the articles of incorporation or bylaws (or similar organizational documents), each as in effect on the Agreement Date, or any currently effective resolution adopted by the board of directors or shareholders of the Bank; (b) contravene, conflict with or result in a violation of, or give any Regulatory Authority or other Person the valid and enforceable right to challenge any of the Contemplated Transactions or to exercise any remedy or obtain any relief under, any Legal Requirement or any Order to which the Bank, or any of their respective assets that are owned or used by them, may be subject, except for any contravention, conflict or violation that is permissible by virtue of obtaining the regulatory approvals necessitated by the Contemplated Transactions, including such approvals under the Federal Deposit Insurance Act, as amended (the “FDIA”) and the Arizona Statutes; (c) contravene, conflict with or result in a violation or breach of any provision of, or give any Person the right to declare a default or exercise any remedy under, or to accelerate the maturity or performance of, or to cancel, terminate or modify any material Contract to which the Bank is a party or by which any of their respective assets is bound; or (d) result in the creation of any lien, charge or encumbrance upon or with respect to any of the assets owned or used by the Bank or any subsidiary of the Bank. Except for the approvals referred to in Section 8.1 and the requisite approval of its shareholders, the Bank is not or will not be required to give any notice to or obtain any consent from any Person in connection with the execution and delivery of this Agreement or the consummation or performance of any of the Contemplated Transactions.

Section 4.4 Bank Capitalization.

(a) The authorized capital stock of the Bank currently consists, and at the Closing will consist, exclusively of 10,000,000 shares of Bank Stock, 1,730,463 of which shares are duly issued, fully paid and non-assessable. The Bank acknowledges that the Merger Consideration was determined based upon the accuracy of the representations and warranties made in this Section with respect to the number of outstanding shares of Bank Stock and the absence of any options (except for the Bank NQSOs and the Bank ISOs) or other rights to purchase additional shares of Bank Stock, and acknowledges that any Breach of such representations and warranties shall be deemed to have a Material Adverse Effect on the Bank for purposes of this Agreement.

(b) None of the shares of Bank Stock have been issued in violation of any federal or state securities laws or any other Legal Requirement. Since December 31, 2004, except as disclosed in or permitted by this Agreement or as provided on Schedule 4.4, no shares of Bank Stock have been purchased, redeemed or otherwise acquired, directly or indirectly, by the Bank and no dividends or other distributions payable in any equity securities of the Bank have been declared, set aside, made or paid to the Bank Shareholders. To the Knowledge of the Bank, none of the shares of authorized capital stock of the Bank are, nor on the Closing will they be, subject to any claim of right inconsistent with this Agreement. Except for the Bank NQSOs and the Bank ISOs and as provided in the Arizona Statutes, as of the Agreement Date, there are no outstanding subscriptions, contracts, conversion privileges, options, warrants, calls or other rights obligating the Bank to issue, sell or otherwise dispose of, or to purchase, redeem or otherwise acquire, any shares of capital stock of the Bank, and except as provided in this Section or otherwise disclosed in this Agreement, the Bank is not a party to any Contract relating to the issuance, purchase, sale or transfer of any equity securities or other securities of the Bank.

True, correct and complete copies of Call Reports for the Bank as of the close of business on December 31, 2002, 2003 and 2004, and for the nine months ended September 30, 2005 (collectively, the “Bank Financial Statements”), are included in Schedule 4.5. The Bank Financial Statements have been prepared on a basis consistent with past accounting practices and as required by applicable Legal Requirements and fairly present the Bank’s financial condition and results of operations at the dates and for the periods presented. The Bank Financial Statements are complete and correct in all material respects and fairly and accurately present the respective financial position, assets, liabilities and results of operations of the Bank as at the respective dates of, and for the periods referred to in, the Bank Financial Statements, subject to normal year-end non-material audit adjustments in amounts consistent with past practice. The Bank Financial Statements do not include any material assets or omit to state any material liabilities, absolute or contingent, or other facts, which inclusion or omission would render the Bank Financial Statements misleading in any material respect as of the respective dates and for the periods referred to in the respective Bank Financial Statements.

Section 4.6 Books and Records. The books of account, minute books, stock record books and other records of the Bank are complete and correct in all material respects and have been maintained in accordance with the Bank’s business practices and all applicable Legal Requirements, including the maintenance of any adequate system of internal controls required by the Legal Requirements.

At the Closing, all of those books and records will be in the possession of the Bank.

Section 4.7 Title to Properties. The Bank has good and marketable title to all assets and properties, whether real or personal, tangible or intangible, that it purports to own, subject to no valid liens, mortgages, security interests, encumbrances or charges of any kind except: (a) as noted in the most recent Bank Financial Statement or on Schedule 4.7; (b) statutory liens for Taxes not yet delinquent or being contested in good faith by appropriate Proceedings and for which appropriate reserves have been established and reflected on the Bank Financial Statements; (c) pledges or liens required to be granted in connection with the acceptance of government deposits or granted in connection with repurchase or reverse repurchase agreements; and (d) minor defects and irregularities in title and encumbrances that do not materially impair the use thereof for the purposes for which they are held (all of such exceptions in clauses (a) through (d) are collectively referred to as “Permitted Exceptions”). Except as set forth on Schedule 4.7, the Bank as lessee has the right under valid and existing leases to occupy, use, possess and control any and all of the respective property leased by it. Except where any failure would not reasonably be expected to have a Material Adverse Effect on the Bank, all buildings and structures owned by the Bank lie wholly within the boundaries of the real property owned or validly leased by it, and do not encroach upon the property of, or otherwise conflict with the property rights of, any other Person.

Section 4.8 Condition and Sufficiency of Assets. The buildings, structures and equipment of the Bank are structurally sound, are in good operating condition and repair, and are adequate for the uses to which they are being put, and none of such buildings, structures or equipment is in need of maintenance or repairs except for ordinary, routine maintenance and repairs that are not material in the aggregate in nature or in cost.

Section 4.9 Loans; Allowance for Loan and Lease Losses. Except as set forth in Schedule 4.9, all loans and loan commitments extended by the Bank and any extensions, renewals or continuations of such loans and loan commitments (the “Bank Loans”) were made in accordance with the lending policies of the Bank in the Ordinary Course of Business. The Bank Loans are evidenced by appropriate and sufficient documentation and constitute valid and binding obligations to the Bank enforceable in accordance with their terms, except as enforceability may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors’ rights generally and subject to general principles of equity. All such Bank Loans are, and at the Closing will be, free and clear of any encumbrance or other charge (except for liens, if any, set forth on Schedule 4.7) and the Bank has complied, and at the Closing will have complied with all Legal Requirements relating to such Bank Loans, except where any such failure to comply would not reasonably be expected to have a Material Adverse Effect on the Bank. The allowance for loan and lease losses of the Bank is and will be on the Closing adequate in all material respects to provide for possible or specific losses, net of recoveries relating to loans previously charged off, and contains and will contain an additional amount of unallocated reserves for unanticipated future losses at an adequate level. To the Knowledge of the Bank: (i) none of the Bank Loans is subject to any material offset or claim of offset; and (ii) the aggregate loan balances in excess of the Bank’s allowance for loan and lease losses are, based on past loan loss experience, collectible in accordance with their terms (except as limited above) and all uncollectible loans have been charged off.

Except as set forth on Schedule 4.10, the Bank has no material liabilities or obligations of any nature (whether absolute, accrued, contingent or otherwise), except for liabilities or obligations reflected or reserved against in the Bank Financial Statements and current liabilities incurred in the Ordinary Course of Business since the respective dates thereof. Except as set forth on Schedule 4.10, since the date of the latest Bank Financial Statement, there has not been any change in the business, operations, properties, prospects, assets or condition of the Bank, and, to the Bank’s Knowledge, no event has occurred or circumstance exists, that has had or would reasonably be expected to have a Material Adverse Effect on the Bank.

Section 4.11 Taxes. The Bank has duly filed all material Tax Returns required to be filed by it, and each such Tax Return is complete and accurate in all material respects. The Bank has paid, or made adequate provision for the payment of, all Taxes (whether or not reflected in Tax Returns as filed or to be filed) due and payable by the Bank, or claimed to be due and payable by any Regulatory Authority, and is not delinquent in the payment of any Tax, except such Taxes as are being contested in good faith and as to which adequate reserves have been provided. There is no claim or assessment pending or, to the Knowledge of the Bank, Threatened against the Bank for any Taxes owed by any of them. No audit, examination or investigation related to Taxes paid or payable by the Bank is presently being conducted or, to the Knowledge of the Bank, Threatened by any Regulatory Authority.

Section 4.12 Compliance with ERISA. Except as set forth on Schedule 4.12, all employee benefit plans (as defined in Section 3(3) of ERISA) and all Bank Employee Benefit Plans established or maintained by the Bank or to which the Bank contributes, are in compliance with all applicable requirements of ERISA, and are in compliance with all applicable requirements (including qualification and non-discrimination requirements in effect as of the Closing) of the Code for obtaining the tax benefits the Code thereupon permits with respect to such employee benefit plans. No such employee benefit plan has any amount of unfunded benefit liabilities (as defined in Section 4001(a)(18) of ERISA) for which the Bank would be liable to any Person under Title IV of ERISA if any such employee benefit plan were terminated as of the Closing. Such employee benefit plans are funded in accordance with Section 412 of the Code (if applicable). There would be no obligations of the Bank under Title IV of ERISA relating to any such employee benefit plan that is a multi-employer plan if any such plan were terminated or if the Bank withdrew from any such plan as of the Closing.

Except in the Ordinary Course of Business with respect to any Bank Loan, the Bank has not given to or received from any other Person, at any time since January 1, 2002, any notice or other communication (whether oral or written) regarding any actual, alleged, possible or potential violation or breach of, or default under, any Contract, that has not been terminated or satisfied prior to the Agreement Date.

Each policy is in full force and effect (except for any expiring policy which is replaced by coverage at least as extensive). All premiums due on such policies have been paid in full.

Section 4.19 Compliance with Environmental Laws. Except as set forth on Schedule 4.19, there are no actions, suits, investigations, liabilities, inquiries, Proceedings or Orders involving the Bank or its assets that are pending or, to the Knowledge of the Bank, Threatened, nor to the Knowledge of the Bank is there any factual basis for any of the foregoing, as a result of any asserted failure of the Bank, or any predecessor thereof, to comply with any federal, state, county and municipal law, including any statute, regulation, rule, ordinance, Order, restriction and requirement, relating to underground storage tanks, petroleum products, air pollutants, water pollutants or process waste water or otherwise relating to the environment or toxic or hazardous substances or to the manufacture, processing, distribution, use, recycling, generation, treatment, handling, storage, disposal or transport of any hazardous or toxic substances or petroleum products (including polychlorinated biphenyls, whether contained or uncontained, and asbestos-containing materials, whether friable or not), including, the Federal Solid Waste Disposal Act, the Hazardous and Solid Waste Amendments, the Federal Clean Air Act, the Federal Clean Water Act, the Occupational Health and Safety Act, the Federal Resource Conservation and Recovery Act, the Toxic Substances Control Act, the Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980 and the Superfund Amendments and Reauthorization Act of 1986, all as amended, and regulations of the Environmental Protection Agency, the Nuclear Regulatory Agency and any state department of natural resources or state environmental protection agency now or at any time hereafter in effect (collectively, the “Environmental Laws”). No environmental clearances or other governmental approvals are required for the conduct of the business of the Bank or the consummation of the Contemplated Transactions. To the Knowledge of the Bank, the Bank is not the owner of any interest in real estate on which any substances have been used, stored, deposited, treated, recycled or disposed of, which substances if known to be present on, at or under such property, would require clean-up, removal or some other remedial action under any Environmental Law.

Section 4.20 Regulatory Filings. The Bank has filed in a timely manner all required filings with all Regulatory Authorities, including the FDIC and the Department. All such filings were accurate and complete in all material respects as of the dates of the filings, and no such filing has made any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements made, in light of the circumstances under which they were made, not misleading.

Section 4.21 Fiduciary Accounts. The Bank has properly administered in all material respects all accounts for which it acts as fiduciary, including accounts for which it serves as trustee, agent, custodian or investment advisor, in accordance with the material terms of the governing documents and applicable Legal Requirements and common law. Neither the Bank nor any of its directors, officers or employees, has committed any breach of trust with respect to any such fiduciary account, and the accountings for each such fiduciary account are true and correct in all material respects and accurately reflect the assets of such fiduciary account.

Section 4.22 Indemnification Claims. To the Bank’s Knowledge, no action or failure to take action by any of its Representatives has occurred that may give rise to a claim or a potential claim by any such Person for indemnification against the Bank under any Contract with, or the corporate indemnification provisions of, the Bank, or under any Legal Requirements.

Section 4.23 Insider Interests. Except as set forth on Schedule 4.23, no officer or director of the Bank, or any member of the Family of any such Person, and no entity that any such Person “controls” within the meaning of Regulation O of the Federal Reserve, has any loan, deposit account or any other agreement with the Bank, any interest in any material property, real, personal or mixed, tangible or intangible, used in or pertaining to the business of the Bank.

Section 4.25 Approval Delays. To the Knowledge of the Bank, there is no reason why the granting of any of the regulatory approvals referred to in Section 8.1 would be denied or unduly delayed. The Bank’s most recent Community Reinvestment Act (“CRA”) rating is “satisfactory” or better.

Section 4.26 Code Sections 280G, 409A and 4999. Except as set forth on Schedule 4.26, no payment that is owed or may become due to any director, officer, employee or agent of the Bank will be non-deductible to the Bank (or, following the Merger, Acquiror or AB&T) or subject to tax under Section 280G, Section 409A or Section 4999 of the Code, nor will the Bank (or, following the Merger, Acquiror or AB&T) be required to “gross up” or otherwise compensate any such person because of the imposition of any tax or excise tax on a payment to such person. Except to the extent required under Section 601 et seq. of ERISA and Section 4980B of the Code, and except as set forth on Schedule 4.26, the Bank does not provide health or welfare benefits to any active employee following such employee’s retirement or other termination of service.

Section 4.27 Disclosure. Neither any representation nor warranty of the Bank in, nor any Schedule to, this Agreement contains any untrue statement of a material fact, or omits to state a material fact necessary to make the statements contained herein or therein, in light of the circumstances under which they were made, not misleading. No notice given pursuant to Section 6.5 will contain any untrue statement or omit to state a material fact necessary to make the statements therein or in this Agreement, in light of the circumstances under which they were made, not misleading.

The execution, delivery and performance of this Agreement by Acquiror and AB&T, and the consummation by each of them of its respective obligations under this Agreement, have been authorized by all necessary actions, except for the approval of AB&T’s shareholders. Subject to such shareholder approval, this Agreement constitutes a legal, valid and binding obligation of each of Acquiror and AB&T enforceable in accordance with its terms, except as such enforcement may be limited by bankruptcy, insolvency, reorganization or other laws affecting creditors’ rights generally and subject to general principles of equity.

(b) Except for ordinary corporate requirements, no “business combination,” “moratorium,” “control share” or other state anti-takeover statute or regulation or any provisions contained in the certificate of incorporation or bylaws or similar organizational documents of Acquiror or any Acquiror Subsidiary: (i) prohibits or restricts Acquiror’s ability to perform its obligations under this Agreement, or its ability to consummate the Contemplated Transactions; (ii) would have the effect of invalidating or voiding this Agreement, or any provision hereof; or (iii) would subject the Bank to any material impediment or condition in connection with the exercise of any of its rights under this Agreement.

To the knowledge of Acquiror and AB&T, neither the execution nor delivery of this Agreement nor the consummation or performance of any of the Contemplated Transactions will, directly or indirectly (with or without notice or lapse of time): (a) contravene, conflict with or result in a violation of any provision of the certificate or articles of incorporation or bylaws, each as in effect on the Agreement Date, or any currently effective resolution adopted by the board of directors or shareholders of, Acquiror or AB&T; or (b) contravene, conflict with or result in a violation of, or give any Regulatory Authority or other Person the valid and enforceable right to challenge any of the Contemplated Transactions or to exercise any remedy or obtain any relief under, any Legal Requirement or any Order to which Acquiror or AB&T, or any of their respective assets that are owned or used by them, may be subject, except for any contravention, conflict or violation that is permissible by virtue of obtaining the regulatory approvals necessitated by the Contemplated Transactions, including any such approvals under the BHCA, the FDIA, the Delaware General Corporation Law and the Arizona Statutes. Neither Acquiror nor AB&T is or will be required to give any notice to or obtain any consent from any Person in connection with the execution and delivery of this Agreement or the consummation or performance of any of the Contemplated Transactions except such approvals of Regulatory Authorities that are required by law or regulation to consummate the transactions contemplated by this Agreement.

During the same period, the Bank will promptly notify Acquiror of the occurrence of any Breach of any covenant of the Bank in this Agreement or of the occurrence of any event that might reasonably be expected to make the satisfaction of the conditions in Article 9 impossible or unlikely.

Section 6.6 Other Offers.

(a) Until such time, if any, as this Agreement is terminated pursuant to Article 10, the Bank will not, and will cause its Representatives not to, directly or indirectly solicit, initiate or encourage any inquiries or proposals from, discuss or negotiate with, provide any non-public information to, or consider the merits of any unsolicited inquiries or proposals from, any Person (other than Acquiror) relating to any Acquisition Transaction (as defined below) or a potential Acquisition Transaction involving the Bank. Notwithstanding such foregoing restriction, the Bank may provide information at the request of, or enter into negotiations with, a third party with respect to an Acquisition Transaction if the board of directors of the Bank determines, in good faith, that the exercise of its fiduciary duties to the Bank’s shareholders under applicable law, as advised by its counsel, requires it to take such action, and, provided further, that the Bank may not, in any event, provide to such third party any information which it has not provided to Acquiror. The Bank shall promptly notify Acquiror orally and in writing in the event it receives any such inquiry or proposal and shall provide reasonable detail of all relevant facts relating to such inquiries, along with a summary of the advice provided by its counsel.

The Bank and its board of directors acting as a board shall recommend to the Bank Shareholders the approval of this Agreement and the Merger and shall solicit from the Bank Shareholders proxies voting only in favor thereof.

To the maximum extent permitted by applicable law: (a) no claim or right arising out of this Agreement or the documents referred to in this Agreement can be discharged by one party, in whole or in part, by a waiver or renunciation of the claim or right unless in writing signed by the other parties; (b) no waiver that may be given by a party will be applicable except in the specific instance for which it is given; and (c) no notice to or demand on one party will be deemed to be a waiver of any obligation of such party or of the right of the party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement.

Section 12.5 Modification. This Agreement may only be amended by a written agreement executed by the party to be charged with the amendment.

▇▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇ ▇▇▇▇▇

Re: Acquisition of Bank of the Southwest by Heartland Financial USA, Inc.

Ladies and Gentlemen:

We have served as special counsel to Bank of the Southwest, an Arizona chartered commercial bank with its main office located in Tempe, Arizona (the “Bank”), in connection with the Agreement and Plan of Merger dated as of December 30, 2005 (the “Agreement”), among the Bank, Heartland Financial USA, Inc., a Delaware corporation (“Heartland”), and Arizona Bank & Trust, an Arizona chartered commercial bank with its main office located in Chandler, Arizona, and a majority controlled subsidiary of Heartland (“AB&T”). Except as specifically defined herein, all capitalized terms used in this letter shall have the meanings given them under the Agreement. This opinion is delivered to you pursuant to Section 2.7(h) of the Agreement.

As counsel for the Bank, we have reviewed the Agreement and also have examined and relied upon such other documents and instruments, and certificates of public officials, and have made such other investigations and inquiries as we have deemed necessary or appropriate for purposes of this opinion. In stating our opinion, we have relied solely upon certificates of officers of the Bank with respect to certain factual matters as we have deemed reasonably necessary. For purposes of this opinion, we have also assumed, without investigation: (a) the legal capacity of each natural Person; (b) the full power and authority of each Person, other than the Bank and its officers, to execute, deliver and perform each document heretofore executed and delivered or hereafter to be executed and delivered, and to do each other act heretofore done or hereafter to be done by such Person; (c) the due authorization, execution and delivery by each Person, other than the Bank and its officers, of each document heretofore executed and delivered or hereafter to be executed and delivered by such Person; (d) the legality, validity, binding effect and enforceability as to each Person, other than the Bank and its officers, of each document heretofore executed and delivered or hereafter to be executed and delivered, and of each other act heretofore done or hereafter to be done by such Person; (e) the genuineness of each signature on and the completeness of each document submitted to us as an original; (f) the conformity to, and the authenticity of, the original of each document submitted to us as a copy; (g) no modification of any provision of any document, nor waiver of any right or remedy; and (h) no exercise of any right or remedy other than in a commercially reasonable and conscionable manner and in good faith.

As to questions of fact material to our opinion that have not been independently established, we have relied upon, without independent verification, the accuracy of the relevant facts stated in the certificates or comparable documents of officers of the Bank and upon the accuracy of the representations and warranties contained in the Agreement. Although we have made no independent investigation or verification of each matter set forth therein, nothing has come to our attention indicating that such reliance by us or by you is not justified. In addition, and particularly with respect to numbered paragraphs 5, 6 and 7 below, we wish to advise you that: (a) we have not been engaged to give substantive attention to any legal or governmental proceedings or orders to which the Bank may be a party; and (b) we have made no special investigation as to the factual matters stated in our opinion, including any search of the dockets or records of any Regulatory Authority, to determine if any such Proceedings are pending or Orders have been entered involving the Bank.

The opinions hereafter expressed are qualified to the extent that the rights, interests and remedies under the Transaction Documents (as defined below) may be subject to or affected by: (a) any bankruptcy, insolvency, bank conservatorship or receivership or similar laws affecting creditors’ rights and remedies generally, and the enforcement thereof; (b) the unavailability of, or any limitation on the availability of, any particular right or remedy (whether in a proceeding in equity or at law) because of general principles of equity; and (c) any limitation insofar as indemnification and contribution provisions thereof may be limited by applicable law.

We express no opinion concerning the applicability to the Bank, or to the Agreement or any other documents, exhibits or schedules delivered in connection with the Merger (collectively, the “Transaction Documents”), of federal, state or local laws, rules, regulations or ordinances relating to: (a) occupational health and safety, environmental siting, impact and discharge, or storage and discharge of flammable or hazardous materials or solid or toxic waste; (b) any federal, state or local tax consequences arising in connection with the transactions contemplated in the Transaction Documents; (c) patent, copyright, service ▇▇▇▇, trade name or trademark rights; or (d) the accuracy, adequacy or legal sufficiency of any personal property descriptions contained in the Transaction Documents.

On the basis of and subject to the foregoing and the qualifications stated below, we are of the opinion that:

1. The Bank is a corporation duly organized, validly existing and in good standing under the laws of the State of Arizona. The Bank has all necessary corporate and regulatory power and authority to own its properties and to carry on its business as it is now being conducted, including the conduct of a banking business in the State of Arizona.

2. The authorized capital stock of the Bank consists of 10,000,000 shares of Bank Stock. To our knowledge, 1,730,463 shares of Bank Stock are duly issued and outstanding, fully paid and non-assessable, no shares of Bank Stock are held by the Bank as treasury shares and, to our knowledge, no shares have been issued in violation of any preemptive right of the Bank’s shareholders. To our knowledge and except as disclosed in the Agreement and the Schedules, there are no other shares of capital stock of the Bank issued and outstanding, and the Bank owns no voting stock or equity securities of any corporation, association, partnership or other entity.

3. To our knowledge, except as disclosed in the Agreement or the Schedules, there is no existing Contract obligating the Bank to issue or sell, or to purchase or redeem, any shares of capital stock of the Bank.

4. The execution, delivery and performance of the Agreement and the Contemplated Transactions have been duly authorized and approved by the Bank’s board of directors and its shareholders, these being the only corporate authorizations thereof required of the Bank under its articles of incorporation and bylaws and under applicable law. The Agreement constitutes the legal, valid and binding obligation of the Bank enforceable in accordance with its terms.

5. The execution, delivery and performance by the Bank of the Agreement will not violate the articles of incorporation or bylaws of the Bank, and will not, to our knowledge, result in a material Breach of or constitute a default under any material Contract or Order of which we have knowledge to which the Bank is a party or to which it or a material portion of any of its properties or assets may be bound.

6. To our knowledge, no consent, approval, authorization or Order of any Regulatory Authority that has not been obtained is required on behalf of the Bank for consummation of the Contemplated Transactions, except for the filing of the articles of merger with the Arizona Corporation Commission.

7. To our knowledge, there are no Proceedings, pending or Threatened, against or affecting the Bank, at law or in equity or before or by any Regulatory Authority, or before any arbitrator of any kind that, in our opinion, based upon such knowledge, are reasonably likely to have a Material Adverse Effect on the Bank.

In addition to the matters set forth above, although we have not independently verified the accuracy or completeness of the statements contained in the Proxy Statement, based upon our knowledge obtained while acting as special counsel to the Bank and our review and discussion of the contents of the Proxy Statement with the representatives of the Bank and the certificates of officers of the Bank verifying certain factual information included therein, nothing has come to our attention during the course of our representation of the Bank that leads us to believe that (except for financial statements, other financial data and information relating to or supplied by Heartland or AB&T, and financial statements and other financial data supplied by the Bank included therein as to which we do not express any belief) the Proxy Statement, at the time the Proxy Statement was first mailed to the shareholders of the Bank, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or as necessary to make the statements therein, in light of the circumstances under which they were made, not misleading.

With respect to the opinions expressed above, we are qualified to practice law in the State of Arizona and express no opinion concerning any law other than the laws of the State of Arizona and the laws of the United States of America, provided, however, that with your consent and approval, we have assumed for the purposes of the opinion expressed in the last sentence of paragraph 4 above, that the laws of the State of Iowa are the same in all material respects as the laws of the State of Arizona.

To the extent any statement is made subject “to our knowledge” or words of like import, such statement is limited to facts actually known, or facts that would have been known after reasonable inquiry concerning the statement made, by attorneys in our office who have participated in the representation of the Bank in connection with the Contemplated Transactions.

This opinion is being furnished to you solely for your benefit in connection with the Agreement. It may not be relied upon by, nor a copy of it delivered to any other party, without our prior written consent. This opinion is based upon our knowledge of the law and facts as of the date hereof, and we assume no duty to communicate with you with respect to any matter that comes to our attention hereafter.

Very truly yours,

Section 10. Waivers.

Furthermore, if the scope and any restriction or requirement contained in this Agreement is too broad to permit enforcement of such restriction or requirement to its fullest extent, then such restriction or requirement shall be enforced to the maximum extent permitted by law, and each of the parties hereto consents and agrees that any court of competent jurisdiction may so modify such scope in any proceeding brought to enforce such restriction or requirement.

Section 15. Assignments, Successors and No Third Party Rights. None of the parties to this Agreement may assign any of its rights under this Agreement without the prior written consent of the other parties. Subject to the preceding sentence, this Agreement and every representation, warranty, covenant, agreement and provision hereof shall be binding upon, and inure to the benefit of, the parties hereto and their respective successors and permitted assigns.

Exhibit C

Form of Voting Agreement

This Voting Agreement (this “Agreement”) is entered into as of December 30, 2005, among Heartland Financial USA, Inc., a Delaware corporation (“Heartland”), Bank of the Southwest, an Arizona chartered commercial bank with its main office located in Tempe, Arizona (“Southwest”), and each of the Bank’s directors who owns voting stock of the Bank (collectively referred to in this Agreement as the “Principal Stockholders,” and individually as a “Principal Stockholder.”)

Recitals

A. As of the date hereof, each Principal Stockholder is the owner of the number of shares of the Bank’s common stock, no par value per share ("Bank Stock"), as is set forth opposite such Principal Stockholder’s name on the signature page attached hereto and such number of shares represents approximately the percentage of the issued and outstanding shares of the Bank’s voting stock which is also set forth thereon opposite such Principal Stockholder’s name.

B. Heartland is contemplating the acquisition of the Bank by means of a merger (the “Merger”) of the Bank with and into Arizona Bank & Trust, an Arizona chartered commercial bank with its main office located in Chandler, Arizona, and a majority controlled subsidiary of Heartland (“AB&T”), pursuant to an Agreement and Plan of Merger dated of even date herewith (the “Merger Agreement”).

C. Heartland and AB&T are unwilling to expend the substantial time, effort and expense necessary to implement the Merger, including applying for and obtaining necessary approvals of regulatory authorities, unless all of the Principal Stockholders enter into this Agreement.

D. Each Principal Stockholder believes it is in his or her best interest as well as the best interest of the Bank for Heartland and AB&T to consummate the Merger.

Agreements

In consideration of the foregoing premises, which are incorporated herein by this reference, and the covenants and agreements of the parties herein contained, and as an inducement to Heartland and AB&T to enter into the Merger Agreement and to incur the expenses associated with the Merger, the parties hereto, intending to be legally bound, hereby agree as follows:

Section 1. Definitions; Construction. All terms that are capitalized and used herein (and are not otherwise specifically defined herein) shall be used in this Agreement as defined in the Merger Agreement. The parties hereby incorporate by this reference the principles of construction set forth in Section 1.2 of the Merger Agreement.

Section 2. Representations and Warranties. Each Principal Stockholder represents and warrants that as of the date hereof, he or she:

(a) owns beneficially or owns of record the number of shares of Bank Stock as is set forth opposite such Principal Stockholder’s name on the signature page attached hereto, all of which shares are free and clear of all liens, pledges, security interests, claims, encumbrances, options, voting agreements, proxies, agreements to sell and commitments of every kind (collectively, “Encumbrances”);

(b) has the sole, or joint with any other Principal Stockholder, voting power with respect to such shares of Bank Stock, and except as described in the Merger Agreement, that he or she does not own or hold any rights to acquire any additional shares of the Bank’s capital stock (by exercise of stock option or otherwise) or any interest therein or any voting rights with respect to any additional shares; and

(c) has all necessary power and authority to enter into this Agreement and further represents and warrants that this Agreement is the legal, valid and binding agreement of such Principal Stockholder, and is enforceable against such Principal Stockholder in accordance with its terms.

Section 3. Voting Agreement. Each Principal Stockholder hereby agrees that at any meeting of the Bank’s stockholders however called, and in any action by written consent of the Bank’s stockholders, such Principal Stockholder shall vote, or cause to be voted, all shares of Bank Stock now or at any time hereafter owned or controlled by him or her:

(a) in favor of the Merger and the other Contemplated Transactions as described in the Merger Agreement;

(b) against any acquisition of control of any capital stock of the Bank through purchase, merger, consolidation or otherwise, or the acquisition by any method of a substantial portion of the assets of the Bank, in any such case by any party other than Heartland or AB&T (an “Alternate Proposal”);

(c) against any action or agreement that would reasonably be expected to result in a material breach of any covenant, representation or warranty or any other obligation of the Bank under the Merger Agreement; and

(d) against any action or agreement that would reasonably be expected to impede or interfere with the Contemplated Transactions, including any: (i) change in the Bank’s board of directors; (ii) change in the Bank’s present capitalization; or (iii) other material change in the Bank’s corporate structure or business, in each such case except as otherwise agreed to in writing by Heartland and AB&T.

Section 4. Additional Covenants. Except as required by law, each Principal Stockholder agrees that he or she will:

(a) not, and will not permit any of his or her Affiliates, prior to the Effective Time to sell, assign, transfer or otherwise dispose of, create an Encumbrance with respect to, or permit to be sold, assigned, transferred or otherwise disposed of, any Bank Stock owned of record or beneficially by such Principal Stockholder, whether such shares of Bank Stock are owned of record or beneficially by such Principal Stockholder on the date of this Agreement or are subsequently acquired by any method, except: (i) for transfers by will or by operation of law (in which case this Agreement shall bind the transferee); (ii) with the prior written consent of Heartland and AB&T (which consent shall not be unreasonably withheld), for any sales, assignments, transfers or other dispositions necessitated by hardship; or (iii) as Heartland and AB&T may otherwise agree in writing;

(b) not, and will not permit any of his or her Affiliates, directly or indirectly (including through its Representatives), to initiate, solicit or encourage any discussions, inquiries or proposals with any third party relating to an Alternate Proposal, or provide any such person with information or assistance or negotiate with any such person with respect to an Alternate Proposal or agree to or otherwise assist in the effectuation of any Alternate Proposal;

(c) not vote or execute any written consent to rescind or amend in any manner any prior vote or written consent to approve or adopt the Merger Agreement or any of the other Contemplated Transactions;

(d) at the request of Heartland and AB&T, use his or her best efforts to cause any necessary meeting of the Bank’s stockholders to be duly called and held, or any necessary consent of stockholders to be obtained, for the purpose of approving or adopting the Merger Agreement and the other Contemplated Transactions;

(e) cause any of his or her Affiliates to cooperate fully with Heartland and AB&T in connection with the Merger Agreement and the Contemplated Transactions; and

(f) execute and deliver such additional instruments and documents and take such further action as may be reasonably necessary to effectuate and comply with his or her respective obligations under this Agreement.

Section 5. Termination. Notwithstanding any other provision of this Agreement, this Agreement shall automatically terminate on the earlier of: (a) the date of termination of the Merger Agreement as set forth in Article 11 thereof, as such termination provisions may be amended by the Bank, Heartland and AB&T from time to time; and (b) the Effective Time.

Section 6. Remedies. Each Principal Stockholder understands and acknowledges that if he or she should breach any of his or her covenants contained in this Agreement, the damage to Heartland and AB&T would be indeterminable in view of the inability to measure the ultimate value and benefit to Heartland and AB&T resulting from Heartland’s contemplated future ownership and control of the Bank, and, therefore, that neither Heartland nor AB&T would have an adequate remedy at law to compensate Heartland and AB&T for any such breach. Each Principal Stockholder agrees that in addition to any other remedy available to Heartland and AB&T at law or in equity, each of Heartland and AB&T shall be entitled to specific performance of this Agreement by such Principal Stockholder upon application to any court having jurisdiction over the parties. Accordingly, each Principal Stockholder: (a) irrevocably waives, to the extent permitted by law, any defense that he or she might have based on the adequacy of a remedy at law which might be asserted as a bar to specific performance, injunctive relief or other equitable relief; and (b) agrees to the granting of injunctive relief without the posting of any bond and further agrees that if any bond shall be required, such bond shall be in a nominal amount.

Section 7. Amendment and Modification. This Agreement may be amended, modified or supplemented at any time by the written approval of such amendment, modification or supplement by the Bank, Heartland, AB&T and the Principal Stockholder directly affected by such amendment, modification or supplement.

Section 8. Entire Agreement. This Agreement evidences the entire agreement among the parties hereto with respect to the matters provided for herein and there are no agreements, representations or warranties with respect to the matters provided for herein other than those set forth herein and in the Merger Agreement and written agreements related thereto. Except for the Merger Agreement, this Agreement supersedes any agreements among any of the Bank, its stockholders, Heartland or AB&T concerning the acquisition, disposition or control of any Bank Stock.

Section 9. Absence of Control. Subject to any specific provisions of this Agreement, it is the intent of the parties to this Agreement that neither Heartland nor AB&T by reason of this Agreement shall be deemed (until consummation of the Contemplated Transactions) to control, directly or indirectly, any other party and shall not exercise, or be deemed to exercise, directly or indirectly, a controlling influence over the management or policies of any such other party. Pursuant to Section 2.10 of the Merger Agreement, nothing contained herein shall be deemed to grant Heartland an ownership interest in any shares of Bank Stock.

Section 10. Informed Action. Each Principal Stockholder acknowledges that he or she has had an opportunity to be advised by counsel of his or her choosing with regard to this Agreement and the transactions and consequences contemplated hereby. Each Principal Stockholder further acknowledges that he or she has received a copy of the Merger Agreement and is familiar with its terms.

Section 11. Severability. The parties agree that if any provision of this Agreement shall under any circumstances be deemed invalid or inoperative, this Agreement shall be construed with the invalid or inoperative provisions deleted and the rights and obligations of the parties shall be construed and enforced accordingly.

Section 12. Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute but one and the same instrument.

Section 13. Governing Law. All questions concerning the construction, validity and interpretation of this Agreement and the performance of the obligations imposed by this Agreement shall be governed by the internal laws of the State of Iowa applicable to agreements made and wholly to be performed in such state without regard to conflicts of laws.

Section 14. Jurisdiction and Service of Process. Any action or proceeding seeking to enforce any provision of, or based on any right arising out of, this Agreement shall be brought only in the courts of the State of Iowa, County of Dubuque or, if it has or can acquire jurisdiction, in the United States District Court serving the County of Dubuque, and each of the parties consents to the jurisdiction of such courts (and of the appropriate appellate courts) in any such action or proceeding and waives any objection to venue laid therein. Process in any action or proceeding referred to in the preceding sentence may be served on any party anywhere in the world.

Section 15. Successors; Assignment. This Agreement shall be binding upon and inure to the benefit of the Bank and Heartland, and their successors and permitted assigns, and the Principal Stockholders and their respective spouses, executors, personal representatives, administrators, heirs, legatees, guardians and other legal representatives. This Agreement shall survive the death or incapacity of any Principal Stockholder. This Agreement may be assigned only by Heartland, and then only to a subsidiary of Heartland.

This Consulting And Non-Competition Agreement (this “Agreement”), is entered into as of December 30, 2005, among Heartland Financial USA, Inc., a Delaware corporation (“Heartland”); Arizona Bank & Trust, an Arizona chartered commercial bank with its main office located in Chandler, Arizona, and a majority controlled subsidiary of Heartland (“AB&T”); and ▇▇▇▇ ▇▇▇▇▇▇▇▇ (“Consultant”).

Recitals

A. Heartland, AB&T and Bank of the Southwest, an Arizona chartered commercial bank with its main office located in Tempe, Arizona (“Southwest”), have entered into an Agreement and Plan of Merger of even date herewith (the “Merger Agreement”) providing for the merger of Southwest with and into AB&T (the “Merger”).

B. Consultant is currently the Chairman of the Board of Southwest and is familiar with the business, operations and properties of Southwest.

C. For purposes of facilitating a smooth transition in ownership and control, an effective consolidation of Southwest’s operations with those of AB&T and the continued success of the combined operations of AB&T and Southwest, Heartland wishes to secure Consultant’s services for a period following the Closing.

D. Consultant is willing to make his services available to Heartland on the terms and conditions hereinafter set forth.

Agreements

In consideration of the foregoing premises and the following mutual promises, covenants and agreements, the parties hereby agree as follows:

Section 1. Engagement. Heartland offers to engage Consultant, and Consultant hereby accepts such engagement, to provide services to Heartland and AB&T as a consultant for the period established under Section 4(a) (the “Term”).

Section 2. Services. During the Term, Consultant shall serve as a director and as the vice chairman of AB&T. He shall also hold himself available during regular business hours to perform such services in connection with the transition of the ownership and operation of the business and assets of Southwest acquired by Heartland pursuant to the Merger Agreement, as the respective executive officers of Heartland or AB&T may reasonably request, and to perform such other services as AB&T or Heartland may reasonably request to promote the success of AB&T, provided, however, that Consultant shall not be required to work any more than an average of twenty-five (25) hours per week in performing the services described in this Agreement. The services which may be required of Consultant hereunder may include, business development; providing general business advice with respect to the gathering of deposits and the making of loans by AB&T; promoting sound banking practices of AB&T; promoting Heartland and AB&T and their respective products and services in communities that are served by Heartland and AB&T and their respective Affiliates (as defined in the Merger Agreement); promoting the recognition and acceptance of Heartland and AB&T among Southwest’s customers; and otherwise facilitating the transition of ownership and control and the effective consolidation of Southwest’s operations with those of Heartland and AB&T. Either or both of Heartland and AB&T may, in their respective sole and absolute discretion, engage other employees or independent contractors to perform any or all of the services for which Consultant is available under this Section.

Section 3. Compensation. As compensation for the consulting services to be provided under Section 2 and for compliance with the covenants in Section 5, Consultant shall receive the following compensation, expense reimbursement and other benefits:

(a) Consulting Fees. Consultant shall receive annual consulting fees of Eighty Five Thousand Dollars ($85,000) (the “Consulting Fees”). The annual Consulting Fees shall be payable in equal monthly installments with each installment to be paid in arrears on the first business day of each month. Consultant shall be eligible, at the discretion of AB&T’s board of directors, to receive cash bonuses on comparable terms as members of AB&T’s senior management, based upon the performance of AB&T.

(b) Stock Options. Consultant shall be considered for grants of options to purchase shares of Heartland stock, all subject to the discretion of the Compensation Committee of Heartland’s board of directors.

(c) Automobile Allowance. AB&T shall pay to Consultant on a monthly basis the sum of Eight Hundred Dollars ($800) as an automobile allowance. Consultant shall be responsible for all expenses for fuel, maintenance, repairs and insurance relating to his automobile. The payment to Consultant of this automobile allowance shall be reflected annually, as the same may be required, on any tax form provided by AB&T to Consultant and shown as additional compensation for income tax purposes.

(d) Country Club Dues. Because Consultant intends to engage in business development and customer relations through customer entertainment at his country club, Heartland agrees during the Term to reimburse Consultant for his monthly country club dues.

(e) Reimbursement of Expenses. If in connection with the performance of business development and customer relations, and/or other services hereunder at the request of Heartland or AB&T, Consultant incurs out-of-pocket costs for expenses for travel, meals and lodging or other reasonable expenses of a type for which other providers of professional services to Heartland or AB&T would be reimbursed, he shall be entitled to reimbursement therefor by Heartland or AB&T in accordance with the reasonable standards and procedures established by Heartland or AB&T and, in the case of either, expressly communicated to Consultant.

Section 4. Term; Termination; Payments on Termination.

(a) Term. The Term shall be for a term of two (2) years beginning on the Effective Date, and shall automatically extend for one (1) additional year on the second anniversary of the Effective Date (the “Automatic Extension”), unless the Automatic Extension is terminated by either party effective by written notice to that effect delivered to the other not less than ninety (90) days prior to the second anniversary of the Effective Date. If the Automatic Extension is terminated, then Consultant’s employment hereunder shall terminate as of the last day of the original two (2) year Term. The parties agree that the Effective Date under this Agreement shall be the Closing Date, as defined in the Merger Agreement, provided, however, that if the Merger Agreement is terminated, this Agreement shall also terminate automatically and simultaneously.

(b) Voluntary Termination by Consultant. If Consultant voluntarily terminates his services under this Agreement, then AB&T shall only be required to pay Consultant his Consulting Fees as shall have accrued through the effective date of such termination, and AB&T shall have no further obligations to Consultant.

(c) Premature Termination by AB&T.

(i) If this Agreement is terminated by AB&T prior to the last day of the Term for any reason other than a termination for Cause (as defined below), then notwithstanding any mitigation of damages by Consultant, AB&T shall pay Consultant an amount equal to the remaining Consulting Fees that Consultant would have been entitled to receive through the second anniversary of the Effective Date.

(ii) Payment to Consultant of such remaining Consulting Fees will be made on a monthly basis during the remaining Term. At the election of AB&T, payments may be made in a lump sum discounted to their present value using the prime rate of interest as of the date of termination. Such payments shall not be reduced in the event Consultant obtains other employment following the termination of employment by AB&T.

(d) Termination for Cause. This Agreement may be terminated for cause as hereinafter defined. “Cause” shall mean: (i) Consultant’s death; (ii) Consultant’s “Permanent Disability,” which shall mean Consultant’s inability, as a result of physical or mental incapacity, substantially to perform his duties hereunder for a period of three (3) consecutive months; (iii) a material violation by Consultant of any applicable law or regulation with respect to the business of AB&T or Heartland; (iv) Consultant being found guilty of a felony or an act of dishonesty in connection with the performance of his duties as a consultant of AB&T, or which disqualifies Consultant from serving as a director of AB&T; or (v) the willful or negligent failure of Consultant to perform his duties hereunder in any material respect. If there is a dispute regarding Consultant’s Permanent Disability, each of Consultant and AB&T shall choose a physician who together will choose a third physician to make a final determination thereof. Upon a termination of Consultant’s employment with AB&T for Cause, then AB&T shall only be required to pay Consultant his Consulting Fees as shall have accrued through the effective date of such termination, and AB&T shall have no further obligations to Consultant.

(e) Payments Upon Death. If any accrued but unpaid Consulting Fees are due and owing under this Agreement at the death of Consultant, then AB&T shall pay such fees to any beneficiary who Consultant may designate in writing, or failing such designation, to the executor of his estate, in full settlement and satisfaction of all claims and demands on behalf of Consultant under the terms of this Agreement.

(f) Payments Prior to Permanent Disability. Consultant shall be entitled to the compensation and benefits provided for under this Agreement for any period during the Term and prior to the establishment of Consultant’s Permanent Disability. Notwithstanding anything contained in this Agreement to the contrary, until the date specified in a notice of termination relating to Consultant’s Permanent Disability, Consultant shall be entitled to return to his positions with AB&T as set forth in this Agreement in which event no Permanent Disability of Consultant will be deemed to have occurred.

Section 5. Restrictive Covenants.

(a) Confidential Information. Consultant acknowledges that, during the course of his engagement with AB&T, Consultant may produce and have access to confidential and/or proprietary non-public information concerning AB&T and its Affiliates, including marketing materials, customers lists, records, data, trade secrets, proprietary business information, pricing lists and policies, strategic planning, commitments, plans, procedures, litigation, pending litigation and other information not generally available to the public (collectively, “Confidential Information”). Consultant agrees not to directly or indirectly use, disclose, copy or make lists of Confidential Information for the benefit of anyone other than Heartland or AB&T, either during or after his engagement under this Agreement, except to the extent that such information is or thereafter becomes lawfully available from public sources, or such disclosure is authorized in writing by Heartland or AB&T, required by law or any competent administrative agency or judicial authority, or otherwise as reasonably necessary or appropriate in connection with performance by Consultant of his duties hereunder. Consultant agrees that, if he receives a subpoena or other court order or is otherwise required by law to provide information to a governmental authority or other person concerning the activities of AB&T or any of its Affiliates, or his activities in connection with the business of AB&T or any of its Affiliates, Consultant will immediately notify AB&T of such subpoena, court order or other requirement and deliver forthwith to AB&T a copy thereof and any attachments and non-privileged correspondence related thereto. Consultant shall take reasonable precautions to protect against the inadvertent disclosure of Confidential Information. Consultant agrees to abide by AB&T’s reasonable policies, as in effect from time to time, respecting avoidance of interests conflicting with those of AB&T and its Affiliates. In this regard, Consultant shall not directly or indirectly render services to any person or entity in connection with the design, development, marketing, sale or administration of any service, product, plan or program where Consultant’s service would involve the use or disclosure of Confidential Information. Consultant agrees not to use any Confidential Information to guide him in searching publications or other publicly available information, selecting a series of items of knowledge from unconnected sources and fitting them together to claim that he did not violate any agreements set forth in this Agreement.

(b) Documents and Property. All records, files, documents and other materials or copies thereof relating to the business of AB&T and its Affiliates, which Consultant shall prepare, receive, or use, shall be and remain the sole property of AB&T and, other than in connection with performance by Consultant of his duties hereunder, shall not be removed from the premises of AB&T or any of its Affiliates without AB&T’s prior written connect, and shall be promptly returned to AB&T upon Consultant’s termination of engagement together with all copies, magnetic disks or tapes, recordings, abstracts, notes or reproductions of any kind made from or about the documents, software and tangible items or information they contain.

(c) Non-Competition and Non-Solicitation.

(i) AB&T and Consultant have jointly reviewed the customer lists and operations of AB&T and have agreed that the primary service area of AB&T’s lending and deposit taking functions in which Consultant will actively participate will extend to an area that encompasses Maricopa County, Arizona (the “Restrictive Area”). Therefore, as an essential ingredient of and in consideration of this Agreement and his engagement by Heartland and AB&T, Consultant agrees that during the Term and for the one year period following the end of the Term (the “Restrictive Period”), he will not, except with the express prior written consent of Heartland and AB&T, directly or indirectly, do any of the following (all of which are collectively referred to in this agreement as the “Restrictive Covenant”):

(A) become an officer, employee, consultant, director or trustee of, or provide services, directly or indirectly, in any capacity whatsoever to, any person, firm, partnership, corporation or trust which owns or operates, a bank, savings and loan association, credit union or similar financial institution (a “Financial Institution”) with an office located, or to be located at an address identified in a filing with any regulatory authority, within the Restrictive Area; provided however, that the ownership by Consultant of shares of the capital stock of any Financial Institution which shares are listed on a securities exchange or quoted on the National Association of Securities Dealers Automated Quotation System and which do not represent more than one percent (1%) of the institution’s outstanding capital stock, shall not violate any terms of this Agreement;

(B) solicit or offer employment to any officer or employee of AB&T or any of its Affiliates;

(C) initiate any information, advice or recommendation with respect to any officer or employee of AB&T or any of its Affiliates that is intended, or that a reasonable person acting in like circumstances would expect, to have the effect of causing any such officer or employee to terminate his or her employment and accept employment or become affiliated with, or provide services for compensation in any capacity whatsoever to, such other entity or person; or

(D) except as a representative of AB&T or any of its Affiliates, directly or indirectly, engage in the sale or marketing of any financial institution products or services, insurance products, investment products, investment advisory services or investment brokerage services to any person or entity who is currently, or becomes after the Effective Time (as defined in the Merger Agreement), a customer of AB&T or any of its Affiliates.

(d) Remedies for Breach of Restrictive Covenants. Consultant has reviewed the provisions of this Agreement with legal counsel and Consultant acknowledges and expressly agrees that the covenants contained in this Section are reasonable with respect to their duration, geographical area and scope. Consultant further acknowledges that the restrictions contained in this Section are reasonable and necessary for the protection of the legitimate business interests of Heartland and AB&T, that they create no undue hardships, that any violation of these restrictions would cause substantial injury to Heartland and AB&T and such interests, that Heartland would not have agreed to enter into the Merger Agreement and Heartland and AB&T would not have agreed to employ Consultant without receiving Consultant’s agreement to be bound by these restrictions and that such restrictions were a material inducement to Heartland to enter into the Merger Agreement and for Heartland and AB&T to hire Consultant. In the event of any violation or threatened violation of these restrictions, Heartland or AB&T, in addition to and not in limitation of, any other rights, remedies or damages available to either of them under this Agreement or otherwise at law or in equity, shall be entitled to preliminary and permanent injunctive relief to prevent or restrain any such violation by Consultant and any and all persons directly or indirectly acting for or with him, as the case may be.

Section 6. No Employment Relationship Created. The relationship between Heartland, AB&T and Consultant shall be that of client and independent contractor. Neither Heartland nor AB&T shall assume, and each specifically disclaims, any obligations of an employer to an employee which may exist under applicable law. Consultant shall be treated as an independent contractor for all purposes of federal, state and local income taxes and payroll taxes. Consultant shall be responsible for payment of all taxes, including federal, state and local taxes arising out of Consultant’s activities in accordance with this Agreement, including federal and state personal income tax and social security tax, all as may be required by applicable law or regulation and Heartland or AB&T, as applicable, shall file the appropriate IRS Form 1099s. Consultant shall have the full authority to select the means, manner and method of performing the services to be performed under this Agreement. Consultant shall not be considered by reason of the provisions of this Agreement or otherwise as being an employee of Heartland or AB&T. Except as expressly provided in this Agreement, Consultant shall not be eligible to participate in any employee benefit plans offered by Heartland or AB&T or any of their Affiliates to their respective employees.

Section 7. Successors and Assigns. This Agreement will inure to the benefit of and be binding upon Consultant, his legal representatives and testate or intestate distributees, and Heartland and AB&T, and their respective successors and assigns, including, in the case of Heartland or AB&T, any successor by merger or consolidation or a statutory receiver or any other person or firm or corporation to which all or substantially all of the respective assets and business of Heartland or AB&T may be sold or otherwise transferred.

Section 8. Entire Agreement; Modifications; Survival. This Agreement constitutes the entire agreement between the parties respecting the subject matter hereof, and supersedes all prior negotiations, undertakings, agreements and arrangements with respect thereto, whether written or oral. Consultant agrees that any employment or consulting agreement or arrangement between Consultant and Southwest shall terminate at the Effective Time and that Consultant is entitled to receive no payments thereunder except for accrued compensation for services rendered. Except as otherwise explicitly provided herein, this Agreement may not be amended or modified except by written agreement signed by Consultant and Heartland. Consultant further acknowledges and agrees that Section 5 shall survive the termination of this Agreement.

Section 9. Enforcement. The provisions of this Agreement shall be regarded as divisible and separate; if any of said provisions should be declared invalid or unenforceable by a court of competent jurisdiction, the validity and enforceability of the remaining provisions shall not be affected thereby. Furthermore, if the scope and any restriction or requirement contained in this Agreement is too broad to permit enforcement of such restriction or requirement to its fullest extent, then such restriction or requirement shall be enforced to the maximum extent permitted by law, and Consultant consents and agrees that any court of competent jurisdiction may so modify such scope in any proceeding brought to enforce such restriction or requirement.

Section 10. Governing Law. All questions concerning the construction, validity and interpretation of this Agreement and the performance of the obligations imposed by this Agreement shall be governed by the internal laws of the State of Arizona applicable to contracts made and wholly to be performed in such state without regard to conflicts of laws.

Section 11. Jurisdiction and Service of Process. Any action or proceeding seeking to enforce, challenge or avoid any provision of, or based on any right arising out of, this Agreement shall be brought only in the courts of the State of Arizona, County of Maricopa or, if it has or can acquire jurisdiction, in the United States District Court serving the County of Maricopa, and each of the parties consents to the exclusive jurisdiction of such courts (and of the appropriate appellate courts) in any such action or proceeding and waives any objection to jurisdiction or venue laid therein. Process in any action or proceeding referred to in the preceding sentence may be served on any party anywhere in the world.

Section 12. Legal Fees. All reasonable legal fees paid or incurred by Heartland, AB&T or Consultant pursuant to any dispute or question of interpretation relating to this Agreement shall be paid or reimbursed by the party who or which is not successful on the merits pursuant to a legal judgment or settlement.

Section 13. Waiver. No waiver by either party at any time of any breach by the other party of, or compliance with, any condition or provision of this Agreement to be performed by the other party, shall be deemed a waiver of any similar or dissimilar provisions or conditions at the same time or any prior or subsequent time.

Section 14. Notices. Notices pursuant to this Agreement shall be in writing and shall be deemed given when received; and, if mailed, shall be mailed by United States registered or certified mail, return receipt requested, postage prepaid; and if to Heartland, addressed to the principal headquarters of Heartland, attention: President; if to AB&T, addressed to the principal headquarters of AB&T, attention: President; or, if to Consultant, to the address set forth below Consultant’s signature on this Agreement, or to such other address as the party to be notified shall have given to the other.

Section 15. Construction. In this Agreement, unless otherwise stated or the context otherwise requires, the following uses apply: (a) “including” means “including, but not limited to”; (b) all references to sections are to sections in this Agreement unless otherwise specified; (c) all words used in this Agreement will be construed to be of such gender or number as the circumstances and context require; (d) the captions and headings of sections appearing in this Agreement have been inserted solely for convenience of reference and shall not be considered a part of this Agreement nor shall any of them affect the meaning or interpretation of this Agreement or any of its provisions; and (e) any reference to a document or set of documents in this Agreement, and the rights and obligations of the parties under any such documents, shall mean such document or documents as amended from time to time, and any and all modifications, extensions, renewals, substitutions or replacements thereof.
