ARTICLE II. CONSIDERATION

2.1 MERGER CONSIDERATION. On the Effective Date, without any action on the part of HBI, CBI, or the holder of any of the shares of CBI Common Stock, the Merger shall be effected in accordance with the following terms:

(A) STOCK OR CASH CONSIDERATION. Subject to the provisions of Sections 2.1(B), 2.1(C), 2.1(E) and 2.2, (i) each Holder who is an Accredited Investor shall receive the number of whole shares of HBI Common Stock equal to the product of 16.8153 and the number of shares of such Holder’s CBI Common Stock surrendered for Merger Consideration (“Stock Consideration”) and (ii) each Holder who is not an Accredited Investor shall receive a cash payment equal to the product of (x) $22.00, (y) 16.8153 and (z) the number of shares of such Holder’s CBI Common Stock surrendered for Merger Consideration (“Cash Consideration”). The total Merger Consideration to be paid is $24,999,945.50 (“Aggregate Merger Consideration”) based upon HBI Common Stock being valued at $22 per share. No interest shall be paid on any Merger Consideration.

(B) EXCEPTION SHARES. All shares of CBI Common Stock owned directly by CBI (including treasury shares), or any of its Subsidiaries (in each case other than shares in trust accounts or in another fiduciary capacity, managed accounts and the like or shares held in satisfaction of a debt previously contracted) (the “Exception Shares”) shall be cancelled and retired as of the Effective Date and shall not thereafter represent capital stock of the Surviving Corporation and shall not be exchanged for Merger Consideration or any other consideration.

(C) FRACTIONAL SHARE CONSIDERATION. Notwithstanding any other provision of this Plan, no fractional shares of HBI Common Stock and no certificates, scrip or other evidence of ownership of fractional shares will be issued in the Merger. HBI shall pay to each Holder of CBI Common Stock who would otherwise be entitled to a fractional or partial share of HBI Common Stock an amount of cash equal to $22.00 multiplied by such fraction of a share otherwise owed the Holder (the “Fractional Share Consideration”). No such Holder shall be entitled to dividends, interest, or any other rights in respect to such fractional shares and no interest shall be paid on the Fractional Share Consideration.

(D) RULE 506 EXEMPTION. The offering of HBI Common Stock to Holders of CBI Common Stock who are Accredited Investors (each, an “Eligible Holder”) is being made pursuant to the exemption from registration under Section 4(2) of the Securities Act and Rule 506. Each Eligible Holder must deliver his or her Transmittal Form, including the Required Rule 506 Representations, as a condition to receipt of his or her portion of the Merger Consideration.

(E) POTENTIAL REDUCTION OF MERGER CONSIDERATION; ESCROW. The Aggregate Merger Consideration shall be reduced (the “Merger Consideration Reduction”) on a dollar-for-dollar basis for (1) the after tax effect of any tax adjustments, penalties and interest made to the federal or state income tax returns of CBI as a result or arising out of the examination of CBI by the Internal Revenue Service referred to in Schedule 4.1(BB) which causes CBI to have to pay any income tax for, or attributable to, taxable years 2004, 2005 and 2006 (the “Covered Years”) or which reduces or eliminates the net operating loss or other tax benefit(s) claimed or taken by CBI or its predecessors in its (or their) tax returns for the Covered Years (the “IRS Examination Reduction”) and (2) any Loss or Losses sustained by Centennial on or prior to December 31, 2009 on the loans and borrowers identified (the “Identified Loans”) in a confidential letter from CBI to HBI (which confidentiality is occasioned by confidentiality laws) (the “Loan Reduction”), provided, however, that the Merger

Consideration Reduction shall not exceed $1,000,000 in the case of the IRS Examination Reduction and $2,000,000 in the case of the Loan Reduction. As used in this Section 2.1(E), “Loss” or “Losses” means, as of December 31, 2009, the sum of (a) the amount of the total outstanding principal, accrued and unpaid interest, and any other amounts advanced by Centennial (the “Total Outstanding Balance”) of or on the Identified Loans, (b) the Total Outstanding Balance of any renewals, extensions, refinancings or modifications of the Identified Loans, (c) the Total Outstanding Balance of all other loans to the same borrower, as that term is defined under the rules aggregating loans to one borrower applicable to Centennial whose loans are included as Identified Loans (other than those loans which HBI has agreed in writing shall not constitute a Loss) and (d) the dollar amount of any write-downs, write-offs or similar treatment by Centennial of the Identified Loans. The IRS Examination Reduction and the Loan Reduction shall only result in a Merger Consideration Reduction.

On the Effective Date, HBI shall deduct from the Aggregate Merger Consideration and transfer to the Escrow Agent HBI Common Stock (valued at $22 per share) and cash with a total value of $3,000,000, each in the same proportion of HBI Common Stock and cash as the total Stock Consideration and Cash Consideration bears respectively to the Aggregate Merger Consideration, to be held by the Escrow Agent pursuant to the terms of the Escrow Agreement among HBI, CBI and the Escrow Agent, to be dated as of the Effective Date (the “Escrow Agreement”) for the purpose of effecting the Merger Consideration Reduction. Certificates for the HBI Common Stock subject to the Escrow Agreement shall be issued in the names of the Eligible Holders.

Any dispute arising under or out of this Section 2.1(E) shall be resolved by an independent certified public account, mutually selected by HBI and CBI, whose decision shall be binding on the Parties. The costs of such independent certified public account shall be split equally between HBI and the Holders, unless the independent certified public accountant shall determine that another apportionment of costs is more equitable.

2.2. TRANSMITTAL PROCEDURES.

(A) TENDER OF SHARES OF CBI COMMON STOCK AND DELIVERY OF CONSIDERATION. Any Merger Consideration into which shares of a Holder’s CBI Common Stock are converted on the Effective Date, and any dividends paid on shares of HBI Common Stock issued as Stock Consideration for which the record date for determination of shareholders entitled to such dividends is on or after the Effective Date, will be delivered on the Effective Date to such Holder only upon delivery to HBI of the certificates representing all of such Holder’s shares of CBI Common Stock (or an affidavit for indemnity satisfactory to HBI, in its sole judgment, if any of such certificates are lost, stolen or destroyed). No interest shall be paid on any dividends to which such Holder shall be entitled.

(B) TRANSMITTAL OF SHARES. Each delivery of shares of CBI Common Stock by an Eligible Holder shall be accompanied by a transmittal form, in form and content satisfactory to HBI (the “Transmittal Form”), signed by the Holder(s) of such shares, which Transmittal Form shall, among other things, (i) contain stock powers sufficient to evidence the transfer of such shares to HBI, (ii) represent that the Holder(s) is (are) an Accredited Investor, (iii) make the representations required of Persons acquiring securities pursuant to Rule 506 (the

“Required Rule 506 Representations”), (iv) agree to the restrictions required by Regulation D and Rule 506 and acknowledge that each share of HBI Common Stock to be issued hereunder constitutes Restricted Securities (collectively, the “Required Rule 506 Restrictions”), and (v) agree to any other reasonable restrictions contained in the Transmittal Form. Each Eligible Holder shall submit to HBI a properly completed Transmittal Form at least 10 days prior to the Effective Date, together with certificate(s) evidencing shares of CBI Common Stock owned by such Holder. Failure to submit a properly completed Transmittal Form at least 10 days prior to the Effective Date shall result in that Holder not being deemed to be an Accredited Investor. Once submitted, the Transmittal Form is irrevocable, provided the Merger is consummated hereunder. HBI shall be under no obligation to notify any Persons of any defect in a Transmittal Form. The Transmittal Form shall also include the Holder’s grant of a special power of attorney to the designated Holder Representative. HBI may also require Holders who are not Accredited Investors to also submit a transmittal form, in form and content satisfactory to HBI, to accompany their delivery of CBI Common Stock and designate the Holder Representative.

2.3. CBI SHAREHOLDER RIGHTS; STOCK TRANSFERS. On the Effective Date, holders of CBI Common Stock shall cease to be, and shall have no rights as, shareholders of CBI other than to receive the consideration provided under this ARTICLE II, or (in the event that HBI shall waive the requirement that there be no Dissenting Shareholders) the rights of a Dissenting Shareholder who perfects those rights under the Appraisal Laws. On and after the Effective Date, there shall be no transfers on the stock transfer books of CBI or the Surviving Corporation of the shares of CBI Common Stock that were issued and outstanding immediately prior to the Effective Date.

2.4. RESERVATION OF RIGHT TO REVISE TRANSACTION. In its sole discretion, and notwithstanding any other provision in this Plan to the contrary, HBI may at any time prior to the Effective Date revise the transaction as follows:

(A) HBI may change the method of effecting its acquisition of CBI including, but not limited to, causing CBI to be merged directly into HBI for the purpose of acquiring CBI and becoming the Surviving Corporation in the Merger; provided, however, that (i) no such change shall change the amount, value or kind of consideration to be generally issued to Holders as provided for in this Plan and, provided further that the Merger Consideration set forth in Section 2.1 is not reduced, (ii) no delay caused by such a change shall be the basis upon which HBI terminates this Plan pursuant to Section 7.1(B), and (iii) no such change shall affect the rights and obligations of Centennial’s directors and officers as set forth in ARTICLE VIII.

(B) If HBI elects to change the method of acquisition pursuant to this Section 2.4, CBI will cooperate with and assist HBI with any necessary amendment to this Plan, and with the preparation and filing of such applications, documents, instruments and notices as may be necessary or desirable, in the opinion of counsel for HBI, to obtain all necessary shareholder approvals and approvals of any regulatory agency, administrative body or other governmental entity.

(A) MUTUAL CONSENT. By the mutual consent of the Parties, if the board of directors of each Party so determines by vote of a majority of the members of its entire board;

(B) DELAY. By either Party in the event the Merger is not consummated by the Termination Date, unless the failure of the consummation of the transactions to occur shall be due to the failure of the Party seeking to terminate this Plan to perform its obligations hereunder in a timely manner; provided, however, that neither party may terminate the Plan pursuant to this Section 7.1(B), if such delay results from a change in the method of acquisition pursuant to Section 2.4, and provided, further, that a Party may not terminate the Plan pursuant to this Section 7.1(B) if it is in Material breach of any of the provisions of the Plan;

(C) NO REGULATORY APPROVALS. By either Party, in the event that, absent the Material breach of the terminating Party, any of the required regulatory approvals set forth in Section 6.1(B) are denied (or should any such required approval be conditioned upon a substantial deviation from the transactions contemplated); provided, however, that either Party may extend the term of this Plan for a sixty (60)-day period to prosecute diligently and overturn such denial provided that such denial has been appealed within fifteen (15) Business Days of the receipt thereof; or

(D) [RESERVED]

(E) SECURITIES LAW EXEMPTION. By HBI, in the event it believes, in the exercise of its or its counsel’s reasonable judgment, that the issuance of the HBI Common Stock (1) is not or may not be exempt from registration under the Securities Act pursuant to Rule 506 or any applicable state securities laws, or (2) would require HBI’s registration as a broker-dealer, agent or similar registration under any applicable state securities laws.

7.2. TERMINATION FOR BREACH. This Plan may be terminated prior to the Effective Date, either before or after receipt of required shareholder approvals, by either Party if there has been a Material breach on the part of the other Party of its representations, warranties, covenants, or other agreements set forth herein or in any Schedule or certificate delivered pursuant hereto. The non-breaching Party expressly reserves all rights and remedies available in law or equity if this Agreement is terminated for breach.

ARTICLE VIII. POST-CLOSING MATTERS

8.1. MANAGEMENT OF CBI AND CENTENNIAL.

(A) From the Effective Date, through and including December 31, 2008 (the “Carry-Over Control Period”), the directors and officers of CBI and Centennial as of the Effective Date (and any replacements thereof elected by such directors, or recommended by such directors to HBI to be elected by HBI as the sole shareholder of the Surviving Corporation) shall continue to manage the business and affairs of the Surviving Corporation and Centennial prudently (as if such directors and officers were the owners of the Surviving Corporation and

Centennial), in a safe and sound manner, in accordance with all applicable laws and regulations (including, without limitation, those of any Regulatory Authorities) and in compliance with any policies HBI has adopted or may adopt that are generally applicable to all of its bank Subsidiaries. In managing the business and affairs of the Surviving Corporation and Centennial, such directors and officers shall consult with HBI and its officers, and to the fullest extent possible coordinate the business operations of the Surviving Corporation and Centennial with HBI’s operations and those of HBI’s Subsidiaries.

(B) During the Carry-Over Control Period, HBI shall not take any action the consequence of which shall be to:

(1) Amend the Governing Documents of the Surviving Corporation or Centennial;

(2) Remove, or fail to re-elect, any director of the Surviving Corporation or Centennial serving in such capacity on the Effective Date, or fail to elect any replacements thereof recommended by such directors to HBI to be elected by HBI as the sole shareholder of the Surviving Corporation; or

(3) Otherwise direct the management of the business and affairs of the Surviving Corporation or Centennial;

provided, however, that, notwithstanding the foregoing, HBI may: (i) elect, or require to be elected, one (1) director to the board of each of the Surviving Corporation and Centennial, which director shall serve ex officio on each board committee (and, as may be necessary in connection with the elections or committee membership of such directors, amend or require to be amended the Governing Documents of the Surviving Corporation or Centennial); (ii) remove any director, officer or employee of the Surviving Corporation or Centennial for Cause (as defined below), in the event that such removal shall not have been timely effected by action of the board or an officer of the Surviving Corporation or Centennial after a written request for removal shall be presented to the Surviving Corporation or Centennial by HBI; (iii) cause the Surviving Corporation to be merged into HBI or any Subsidiary of HBI, provided that the control of the business and affairs of Centennial remains subject to this Section 8.1; (iv) cause CBI to obtain from HBI, a Subsidiary of HBI, or any Person designated by HBI, those services set forth on Schedule 8.1 hereto, or such other services as HBI shall hereafter designate; provided, however, that all such services shall be substantially upon the same terms, and at equivalent prices, to those that could be obtained by the Surviving Corporation or Centennial from Third Parties, such determination to be made in the reasonable discretion of the board of directors of the Surviving Corporation or Centennial; (v) take any other action required by law, a Regulatory Authority or a Securities Regulatory Authority; or (vi) terminate at any time this Section 8.1 and Section 8.2, and thereby assume full control of the business and affairs of the Surviving Corporation and Centennial (including, without limitation, the right to remove directors and officers and to elect or appoint their successors), and eliminate any obligation to pay Contingent Consideration, by written notice to the Holders accompanied by payment to the Holders, in the aggregate, of the sum of $4,000,000, with Holders having the option to receive cash or HBI Common Stock valued at $22.00 per share.

(C) For purposes of Section 8.1(B), “Cause” for removal of any director, officer or employee shall be limited to (i) a directive of a Regulatory Authority or a Securities Regulatory Authority requiring the removal of such director, officer or employee; (ii) fraud, misappropriation, embezzlement, theft, dishonesty, breach of any fiduciary duty owed to the Surviving Corporation or Centennial, or similar actions by such director, officer or employee; or (iii) the committing of any act, or failure to act where there is a duty to act, by such director, officer or employee, where such act or omission constitutes an indictable criminal offense.

8.2. CONTINGENT CONSIDERATION.

(A) ADDITIONAL DEFINITIONS. In addition to the definitions set forth elsewhere in this Agreement, the following definitions shall apply for purposes of Sections 2.1(E) and 8.2:

“Adjusted Cash Earnings Before Tax” means, for the period January 1 through December 31, 2008, an amount equal to: (w) Centennial’s income before taxes, plus (x) Core Deposit Intangible Amortization, minus (y) the Imputed Capital Charge, minus (z) interest expense on the trust preferred securities of CBI that were outstanding on the Effective Date; which amount shall be further adjusted by the addition or subtraction, as applicable, of any Other Adjustments.

“Base Amount” means $3,044,100.

“Contingent Cash Consideration” means any amount due under Section 8.2(B) below which Holders shall receive in cash.

“Contingent Stock Consideration” means any amount due under Section 8.2(B) below which Holders shall receive in shares of HBI Common Stock.

“Core Deposit Intangible Amortization” means the amortization of the estimated value related to Centennial’s customer deposit relationships on the Effective Date.

“Holder Representative” means any Holder who has been designated by all Holders and given a special power of attorney by all Holders with respect to the determination of the amount of Contingent Consideration and other matters relating to the transactions contemplated by this Agreement and the Escrow Agreement, and who shall have power to bind all Holders as to such matters.

“Imputed Capital Charge” means the interest imputed on any Capital contributed to Centennial by HBI or any HBI Subsidiary, from the date or dates of such contribution through December 31, 2008, using the Fed Funds rate(s) in effect from time to time during such periods.

“Other Adjustments” means such addition of income or subtraction of expense as shall be determined under Section 8.2(D).

Except as is expressly provided otherwise in this Agreement, terms used in this Section 8.2 are ascribed the meanings given them under GAAP, and computations made pursuant to this Section 8.2 shall be made in accordance with GAAP.

(B) COMPUTATION OF CONTINGENT CONSIDERATION. In the event that Centennial’s Adjusted Cash Earnings Before Tax for the calendar year ending December 31, 2008 shall exceed the Base Amount, such excess shall be multiplied by 9.58, and the resulting sum shall be the Contingent Consideration payable in the aggregate to the Holders; provided, however, that the maximum amount of Contingent Consideration shall be $4,000,000, regardless of the amount by which Adjusted Cash Earnings Before Taxes shall exceed the Base Amount, and provided, further, that the Contingent Consideration so computed shall be reduced, on a dollar-for-dollar basis but not to an amount less than zero and in accordance with the terms and conditions hereof, by the amount of any loss or expense suffered or incurred by HBI as the result of the inaccuracy, breach or violation of any representation, warranty or covenant of CBI contained in Section 4.1 once such losses or expenses suffered or incurred by HBI exceeds $250,000 in the aggregate (the “Deductible”) and then only for losses or expenses incurred by HBI in excess of the Deductible. In no event shall the Contingent Consideration be reduced by more than $2,000,000 for losses or expenses incurred by HBI hereunder. No amount applied as an IRS Examination Reduction or a Loan Reduction against the Merger Consideration Reduction shall also cause a reduction of Contingent Consideration. In the event that HBI determines that it is entitled to a reduction in the Contingent Consideration, HBI shall provide written notice thereof to CBI within three business days from the date that HBI determines that it is entitled to the reduction and such notice shall contain a detailed description and explanation of the facts and circumstances supporting HBI’s rationale for claiming the reduction to the Contingent Consideration. In the event CBI disputes HBI’s claim and such dispute shall not be resolved by agreement of HBI and CBI within ten (10) days after written notice of HBI’s claim hereunder, then such dispute shall be resolved by binding arbitration, held in Little Rock, Arkansas, by the American Arbitration Association under its Commercial Arbitration Rules or other method mutually acceptable to CBI and HBI and neither Party shall have the right to seek resolution or relief from a court of competent jurisdiction except to enforce the award rendered by the arbitrator(s). The aggregate amount of Contingent Consideration, if any, shall be allocated among the Holders in the same proportions and as between Stock Consideration and Cash Consideration as the Merger Consideration was allocated.

(C) PAYMENT OF CONTINGENT CONSIDERATION. Not later than thirty (30) days following the delivery to HBI of consolidated and consolidating audited financial statements for HBI for the year ended December 31, 2008 (or such later time as all disputes have been resolved under Section 8.2(D)), HBI shall cause written notice to be given to the Holders (the “Payment Notice”) that shall (i) state the amount of Contingent Consideration, if any, payable pursuant to this Section 8.2, (ii) request the Holder’s written election (which shall be irrevocable) (the “Holder’s Payment Election”) between receiving the Holder’s portion of the Contingent Consideration as Contingent Stock Consideration (for which purposes a share of HBI Common Stock shall be valued at $22.00) or Contingent Cash Consideration, and (iii) advise that such election shall be made by HBI in the event the Holder’s Payment Election, indicating the Holder’s election, is not returned to HBI within thirty (30) days after the date of the Payment Notice. If the Holder elects to receive Contingent Stock Consideration, he or she must make the

Required Rule 506 Representations and agree to the Required Rule 506 Restrictions or the Holder will only receive Contingent Cash Consideration. Promptly after HBI’s receipt of a Holder’s Payment Election, HBI shall cause to be paid to the Holder his or her portion of the Contingent Consideration, in the form of Contingent Stock Consideration or Contingent Cash Consideration, as elected by the Holder’s Payment Election; provided, however, that no fractional shares of Contingent Stock Consideration shall be paid, such fractional shares, if any, to be paid in Contingent Cash Consideration, and provided, further, that the Contingent Consideration owed to any Holder who has failed to return his or her Payment Election within the thirty (30) day period immediately following the date of the Payment Notice may be paid by HBI, in its discretion, in the form of Contingent Stock Consideration or Contingent Cash Consideration. Notwithstanding anything else to the contrary, all Holders who are not Accredited Investors shall be deemed to have elected to receive Contingent Cash Consideration.

(D) DETERMINING OTHER ADJUSTMENTS; DISPUTE RESOLUTION. Any item of income or expense that would under GAAP be classified as “extraordinary” shall be an Other Adjustment. Additionally, either HBI or the Holder Representative (acting on behalf of the Holders) may, by written notice to the other, propose that a particular income or expense of Centennial be deemed an Other Adjustment based on the fact that such income or expense is of a one-time, non-recurring or non-sustainable nature, or is a result of the accounting treatment of the Merger. In the event that HBI and the Holder Representative are unable to agree whether and in what amount the income or expense shall be an Other Adjustment, or in the event that any other dispute shall arise between HBI and the Holder Representative regarding the determination of the amount of Contingent Consideration, and any such proposal or dispute shall not be resolved by agreement of HBI and the Holder Representative within ten (10) days after written notice of such proposal or dispute has been received by the other party, such matter shall be referred for determination to an independent certified public accountant, mutually selected by HBI and the Holder Representative, whose decision in such matter shall be binding on the Parties. The costs of such independent certified public accountant shall be split equally between HBI and the Holders, unless the independent certified public accountant shall determine that another apportionment of costs is more equitable.

8.3. DEMAND REGISTRATION RIGHTS. To the extent that any Merger Consideration or Contingent Stock Consideration is then held by the Holders and is not eligible for sale pursuant to Rules 144 or 145 under the Securities Act or, as to any Holder, exceeds the 3-month volume limitations set forth therein, the Holders (acting as a group, and provided that such group holds fifty percent (50%) or more of the shares of HBI Common Stock issued as Merger Consideration and Contingent Stock Consideration) shall be entitled to one (1) standard demand registration under the Securities Act of the shares of HBI Common Stock constituting Merger Consideration or Contingent Stock Consideration, such right to be exercised by giving written notice to HBI any time after December 31, 2008 and prior to or on December 31, 2009. Such registration shall be at HBI’s expense (except that the participating Holders shall be responsible for the SEC and NASD registration fees, the underwriting discount, and any fees and expenses of counsel for the participating Holders), and otherwise including such terms and conditions as shall be mutually agreeable to the participating Holders and HBI. The rights under this Section 8.3 shall expire if not exercised by written notice to HBI after December 31, 2008 and prior to or on December 31, 2009, and may be exercised one time only.

ARTICLE IX. OTHER MATTERS

9.1. SURVIVAL. Only the representations, warranties, covenants, or other agreements contained in ARTICLES I, II and VIII of this Plan shall survive the Effective Date, regardless of whether a provision specifically states that such provision survives; provided, however, that the representations, warranties and covenants contained in Section 4.1 shall survive until December 31, 2008 (or such later time as all disputes have been resolved under Section 8.2(B) or (D)), for the purpose of determining any reduction to the Contingent Consideration.

9.2. WAIVER; AMENDMENT.
