AGREEMENT AND PLAN OF MERGER

THIS AGREEMENT AND PLAN OF MERGER, dated as of October 5, 2006 (“Agreement”), is made by and among Integra Bank Corporation, an Indiana corporation (“Integra”), PFC Merger Corp., a Delaware corporation and a wholly-owned subsidiary of Integra (“Sub”), and Prairie Financial Corporation, a Delaware corporation (“Prairie”).

WHEREAS, Integra is registered as a bank holding company under the Bank Holding Company Act of 1956, as amended (the “BHCA”), and is the owner of all of the outstanding capital stock of Integra Bank National Association, a national banking association (“Integra Bank”).

WHEREAS, Prairie is registered as a bank holding company under the BHCA and is the owner of all of the outstanding capital stock of Prairie Bank & Trust Company, an Illinois banking corporation (“Prairie Bank”).

WHEREAS, Integra and Prairie have each determined that it is in the best interests of their respective stockholders for Prairie to merge with Sub upon the terms and subject to the conditions set forth in this Agreement (the “Merger”);

WHEREAS, Prairie has received the opinion of Xxxxx Financial, Inc., its financial advisors, that the consideration to be paid to stockholders of Prairie pursuant to this Agreement is fair from a financial point of view;

WHEREAS, the parties intend that immediately after the Merger becomes effective, Prairie Bank shall merge with and into Integra Bank (the “Bank Merger”); and

WHEREAS, the respective Boards of Directors of Integra, Sub and Prairie have each approved this Agreement and the consummation of the transactions contemplated hereby and approved the execution and delivery of this Agreement.

NOW, THEREFORE, in consideration of the foregoing premises and the representations, warranties and agreements contained herein, the parties hereto hereby agree as follows:

ARTICLE I

THE MERGER AND THE BANK MERGER

Section 1.1 Merger. Subject to the terms and conditions of this Agreement, at the Effective Time (as defined in Section 1.2 below), Prairie and Sub will merge with Prairie as the resulting or surviving corporation (“Surviving Corporation”) and the separate corporate existence of Sub will thereupon cease in accordance with the applicable provisions of the Delaware General Corporation Law (“DGCL”).

Integra may at any time change the method of effecting the combination with Prairie (including, without limitation, the provisions of this Article I) if and to the extent it reasonably deems such change to be desirable, including, without limitation, to provide for Sub to become the Surviving Corporation, to provide for the merger of the Surviving Corporation into Integra or a wholly-owned subsidiary of Integra as a condition to the opinion contemplated in Section 7.2(d) or to change the effective time of the Bank Merger; provided, however, that no such change shall (A) alter or change the amount or kind of consideration to be issued to holders of shares of common stock, par value $1.00 per share (“Prairie Common Stock”), of Prairie as provided for in this Agreement, (B) materially impede or delay consummation of the transactions contemplated by this Agreement, or (C) would result in any material adverse tax consequences to Prairie stockholders not expressly contemplated by this Agreement.

Section 1.2 Effective Time. Prior to the Closing Date (as defined in Section 6.1), Integra and Prairie shall cause a certificate of merger complying with the requirements of the DGCL to be filed with the Secretary of State of the State of Delaware (the “Delaware Certificate of Merger”) specifying that the Merger will become effective at 11:59 p.m. (CDT) on the day on which the Closing Date occurs (the “Effective Time”).

Section 1.3 Effect of Merger. The Merger will have the effects specified in the DGCL. Without limiting the generality of the foregoing, Prairie will continue to be governed by the laws of the State of Delaware, and the separate corporate existence of Prairie and all of its rights, privileges, powers and franchises, public as well as private, and all its debts, liabilities and duties as a corporation organized under the DGCL, will continue unaffected by the Merger.

Section 1.4 Certificate of Incorporation and By-laws. The Certificate of Incorporation and By-laws of Sub in effect immediately prior to the Effective Time shall be the Certificate of Incorporation and By-laws of the Surviving Corporation, until amended in accordance with applicable law.

Section 1.5 Directors and Officers. The directors and officers of Sub immediately prior to the Effective Time will be the directors and officers, respectively, of the Surviving Corporation, from and after the Effective Time, until their successors have been duly elected or appointed and qualified or until their earlier death, resignation or removal in accordance with the terms of the Surviving Corporation’s Certificate of Incorporation and By-laws and the DGCL.

Section 1.6 Additional Actions. If, at any time after the Effective Time, the Surviving Corporation shall consider or be advised that any further deeds, assignments or assurances in law or any other acts are necessary or desirable to (i) vest, perfect or confirm, of record or otherwise, in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of Prairie, or (ii) otherwise carry out the purposes of this Agreement, Prairie and its officers and directors shall be deemed to have granted to the Surviving Corporation an irrevocable power of attorney to execute and deliver all such deeds, assignments or assurances in law or any other acts as are necessary or desirable to (a) vest, perfect or confirm, of record or otherwise, in the Surviving Corporation its right, title or interest in, to or under any of the rights, properties or assets of Prairie or (b) otherwise carry out the purposes of this Agreement and the officers and directors of the Surviving Corporation are authorized in the name of Prairie or otherwise to take any and all such action.

Section 1.7 Bank Merger. Upon the terms and subject to the conditions set forth in this Agreement and the Bank Merger Agreement in the form attached hereto as Exhibit A (the “Bank Merger Agreement”), and in accordance with the National Bank Act, and the Illinois Banking Act (collectively the “Banking Laws”), Prairie Bank will be merged with and into Integra Bank. Prairie Bank shall be the merging association and its separate corporate existence shall cease as of the effective time of the Bank Merger. Integra Bank shall be the surviving association and shall succeed to and assume all rights and obligations of Prairie Bank in accordance with the Banking Laws. The Bank Merger shall have the other consequences provided for in the Bank Merger Agreement and the Banking Laws.

Section 1.8 Absence of Control. Subject to any specific provisions of this Agreement, it is the intent of the parties to this Agreement that neither Integra nor Prairie by reason of this Agreement shall be deemed (until consummation of the transactions contemplated herein) to control, directly or indirectly, the other party or any of its respective subsidiaries and shall not exercise, or be deemed to exercise, directly or indirectly, a controlling influence over the management or policies of such other party or any of its respective subsidiaries.

ARTICLE II

CONVERSION OF SHARES

Section 2.1 Conversion of Shares.

(a) At the Effective Time, each then outstanding share of Prairie Common Stock not owned by Integra or any direct or indirect wholly-owned subsidiary of Integra, except for any such shares of Prairie Common Stock (i) held in the treasury of Prairie, or (ii) owned by Prairie stockholders who have properly demanded appraisal and payment for such shares pursuant to § 262 of the DGCL (“Dissenting Shares”), will be converted into the right to receive either (A) if and only if the conditions set forth in Section 7.3(d) with respect to the election under Section 338(h)(10) of the Internal Revenue Code of 1986, as amended (the “Code”), are satisfied, 5.914 shares of common stock, stated value $1.00 per share and the related rights to purchase shares of Series A Preferred Stock, no par value, which are attached to and trade with such shares (“Integra Common Stock”), of Integra (the “Per Share Stock Consideration”) and $65.26 in cash; or (B) if the conditions set forth in Section 7.3(d) are not satisfied, 5.760 shares of Integra Common Stock (the “Adjusted Per Share Stock Consideration”) and $63.57 in cash. The shares of Integra Common Stock and cash provided for in this Section 2.1(a) are referred to as the “Merger Consideration”.

(b) Each holder of Prairie Common Stock who would otherwise have been entitled to receive a fraction of a share of Integra Common Stock shall receive, in lieu thereof, cash in an amount equal to such fractional part of a share

of Integra Common Stock multiplied by the Market Price (as defined in Section 8.6(a)(vi)).

(c) At the Effective Time, each share of Prairie Common Stock held in Prairie’s treasury immediately prior to the Effective Time shall, by virtue of the Merger, automatically and without any action on the part of the holder thereof, be canceled.

(d) At the Effective Time, each then-outstanding share of Prairie Common Stock owned by Integra or any direct or indirect wholly-owned subsidiary of Integra (except for any shares that are Trust Account Shares or Dissenting Shares) will be canceled and retired.

(e) Each share of common stock of Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one share of common stock, par value $1.00 per share, of the Surviving Corporation from and after the Effective Time.

Section 2.2 Treatment of Stock Options.

(a) At the Effective Time, all rights under any stock option granted by Prairie or its predecessors pursuant to Prairie’s existing stock option plans (collectively, the “Prairie Option Plans”) that remain outstanding and unexercised, whether vested or unvested, immediately prior to the Effective Time, other than the options referenced in Section 2.2(b) and 2.2(c) below (“Unexercised Options”), shall cease to represent a right to acquire shares of Prairie Common Stock and shall be converted into an option to purchase Integra Common Stock (“Integra Substitute Options”) in an amount and at an exercise price determined in this Section 2.2(a) and otherwise subject to the terms of the agreements evidencing the original grants of such options. The adjustments provided in this Section 2.2(a) with respect to Unexercised Options shall be and is intended to be effected in a manner which is consistent with Section 424(a) of the Code. The duration and other terms of the Integra Substitute Options shall be the same as the original option except that all references to Prairie shall be deemed to be references to the Integra.

(b) At the Effective Time, the outstanding stock options to purchase an aggregate of 23,965 shares of Prairie Common Stock at its fair market value on the date of exercise shall be canceled in accordance with the agreement between Prairie and the holders of such options.

(c) At the Effective Time, all rights under the outstanding and unexercised stock options held by Xxxxxxx Xxxxxx not otherwise canceled in accordance with Section 2.2(b) shall cease to represent a right to acquire shares of Prairie Common Stock and shall be converted into the right to receive cash in an amount (less any applicable withholding taxes) equal to (a) the number of shares of Prairie Common Stock subject to the original option, multiplied by (b) the

Merger Consideration minus the applicable exercise price of the original option. For purposes of this Section 2.2(b), the Integra Common Stock portion of the Merger Consideration shall be valued at the Market Price.

Section 2.3 Exchange of Certificates.

(a) Exchange Agent. Prior to the Effective Time, Integra shall designate Integra Bank to act as exchange agent (the “Exchange Agent”) in connection with the Merger pursuant to an exchange agent agreement providing for, among other things, the matters set forth in this Section 2.3. Except as set forth herein, from and after the Effective Time, each holder of a certificate that immediately prior to the Effective Time represented outstanding shares of Prairie Common Stock (a “Certificate”) shall be entitled to receive in exchange therefor, upon surrender thereof to the Exchange Agent, the Merger Consideration for each share of Prairie Common Stock so represented by the Certificate surrendered by such holder thereof. The certificates representing shares of Integra Common Stock included in the Merger Consideration shall be properly issued and countersigned and executed and authenticated, as appropriate.

(b) Notice of Exchange. Promptly after the Effective Time, Integra shall cause the Exchange Agent to mail and/or make available to each record holder of a Certificate a notice and letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Certificate shall pass, only upon proper delivery of the Certificate to the Exchange Agent) advising such holder of the effectiveness of the Merger and the procedures to be used in effecting the surrender of the Certificate in exchange therefor. Upon surrender to the Exchange Agent of a Certificate, together with such letter of transmittal duly executed and completed in accordance with the instructions thereon, and such other documents as may reasonably be requested, the Exchange Agent shall promptly deliver to the person entitled thereto the Merger Consideration for each share of Prairie Common Stock so represented by the Certificate surrendered by such holder thereof, and such Certificate shall forthwith be canceled.

(c) Transfer. If delivery of all or part of the Merger Consideration is to be made to a person other than the person in whose name a surrendered Certificate is registered, it shall be a condition to such delivery or exchange that the Certificate surrendered shall be properly endorsed or shall be otherwise in proper form for transfer and that the person requesting such delivery or exchange shall have paid any transfer and other taxes required by reason of such delivery or exchange in a name other than that of the registered holder of the Certificate surrendered or shall have established to the reasonable satisfaction of the Exchange Agent that such tax either has been paid or is not payable.

(d) Right to Merger Consideration. Subject to Section 2.3(e) below, until surrendered and exchanged in accordance with Section 2.1 or 2.3, each Certificate shall, after the Effective Time, represent solely the right to receive the Merger Consideration, payable to the holder of the shares of Prairie Common

Stock evidenced by such Certificate, together with any dividends or other distributions as provided in Sections 2.3(e) and 2.3(f) below, and shall have no other rights. From and after the Effective Time, Integra shall be entitled to treat such Certificates that have not yet been surrendered for exchange as evidencing the right to receive the aggregate Merger Consideration into which the shares of Prairie Common Stock represented by such Certificates may be converted, notwithstanding any failure to surrender such Certificates. One hundred eighty (180) days following the Effective Time, the Exchange Agent shall deliver to the Surviving Corporation or its successor any shares of Integra Common Stock and funds (including any interest received with respect thereto) which Integra has made available to the Exchange Agent and which have not been disbursed to holders of Certificates, and thereafter such holders shall be entitled to look only to the Surviving Corporation or its successor (subject to abandoned property, escheat or other similar laws) with respect to the Merger Consideration, cash in lieu of fractional shares and dividends or distributions, if any, deliverable or payable upon due surrender of their Certificates. Neither the Exchange Agent nor any party hereto shall be liable to any holder of shares of Prairie Common Stock for any Merger Consideration (or dividends, distributions or interest with respect thereto) delivered in good faith to a public official pursuant to any applicable abandoned property, escheat or similar law.

(e) Distributions with Respect to Unexchanged Certificates. Whenever a dividend or other distribution is declared by Integra on Integra Common Stock, the record date for which is at or after the Effective Time, the declaration shall include dividends or other distributions on all shares issuable pursuant to this Agreement, provided that no dividends or other distributions declared or made with respect to Integra Common Stock shall be paid to the holder of any unsurrendered Certificate with respect to the share of Integra Common Stock represented thereby until the holder of such Certificate shall surrender such Certificate in accordance with this Article II. The Surviving Corporation, or its successor, shall pay any dividends or make any other distributions with a record date prior to the Effective Time which may have been declared or made by Prairie on Prairie Common Stock in accordance with the terms of this Agreement on or prior to the Effective Time and which remain unpaid at the Effective Time.

(f) Lost, Stolen or Destroyed Certificates. In the event that any Certificate shall have been lost, stolen or destroyed, the Exchange Agent shall deliver in exchange for such lost, stolen or destroyed certificate, upon the making of an affidavit of that fact by the holder thereof in form satisfactory to the Exchange Agent, the Merger Consideration, as may be required pursuant to this Agreement; provided, however, that the Exchange Agent may, in its sole discretion and as a condition precedent to the delivery of the Merger Consideration to which the holder of such certificate is entitled as a result of the Merger, require the owner of such lost, stolen or destroyed certificate to deliver a bond in such sum as it may direct as indemnity against any claim that may be

made against Prairie, Integra or the Exchange Agent or any other party with respect to the certificate alleged to have been lost, stolen or destroyed.

(g) Voting With Respect to Unexchanged Certificates. Holders of unsurrendered Certificates will not be entitled to vote at any meeting of Integra shareholders.

(h) No Fractional Shares. No certificates or scrip representing fractional shares of Integra Common Stock shall be issued upon the surrender for exchange of a Certificate or Certificates. No dividends or distributions of Integra shall be payable on or with respect to any fractional share and any such fractional share interest will not entitle the owner thereof to vote or to any rights of shareholders of Integra. In lieu of any such fractional shares, holders of Certificates otherwise entitled to fractional shares shall be entitled to receive promptly from the Exchange Agent a cash payment in an amount equal to the fraction of such share of Integra Common Stock to which such holder would otherwise be entitled multiplied by the Market Price.

Section 2.4 Closing of Prairie’s Transfer Books. The stock transfer books of Prairie shall be closed at the close of business on the business day immediately preceding the date of the Effective Time. In the event of a transfer of ownership of Prairie Common Stock which is not registered in the transfer records of Prairie, the Merger Consideration to be distributed pursuant to this Agreement may be delivered to a transferee, if a Certificate is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by payment of any applicable stock transfer taxes. Integra and the Exchange Agent shall be entitled to rely upon the stock transfer books of Prairie to establish the identity of those persons entitled to receive the Merger Consideration specified in this Agreement for their shares of Prairie Common Stock, which books shall be conclusive with respect to the ownership of such shares. In the event of a dispute with respect to the ownership of any such shares, the Surviving Corporation and the Exchange Agent shall be entitled to deposit any Merger Consideration not already paid represented thereby in escrow with an independent party and thereafter be relieved with respect to any claims to such Merger Consideration.

Section 2.5 Changes in Integra Common Stock. If between the date of this Agreement and the Effective Time, the shares of Integra Common Stock shall be changed into a different number of shares by reason of any reclassification, recapitalization, split-up, combination or exchange of shares, or if a stock dividend thereon shall be declared with a record date within said period, the Merger Consideration shall be adjusted proportionately such that the holders will receive the same amount of Integra Common Stock as if the Integra Common Stock issuable pursuant to the Merger had been outstanding at the record date for such reclassification, recapitalization, split-up, combination, exchange of shares, or dividend.

Section 2.6 Dissenter’s Rights. No holder of Dissenting Shares shall be entitled to the Merger Consideration or cash in lieu of fractional shares or any dividends or other distributions pursuant to this Article II unless and until the holder thereof shall have failed to perfect or shall have effectively withdrawn or lost such holder’s right to appraisal of such shares of Prairie Common Stock under § 262 of the DGCL, and any such stockholder shall be entitled

to receive only the payment provided by § 262 of the DGCL with respect to Dissenting Shares. If any Prairie stockholder who otherwise would be deemed to hold Dissenting Shares shall have failed to properly perfect or shall have effectively withdrawn or lost the right to dissent with respect to any such shares, such shares of Prairie Common Stock shall thereupon be treated as though such shares of Prairie Common Stock had been converted into the right to receive the Merger Consideration pursuant to Section 2.1. Prairie shall give Integra (a) prompt notice of any written demands for appraisal, attempted withdrawals of such demands and any other instruments served pursuant to applicable law received by Prairie relating to Prairie’s rights of appraisal and (b) the opportunity to participate in and direct all negotiations and proceedings with respect to any such demands for appraisal under § 262 of the DGCL. Prairie shall not, except with the prior written consent of Integra (which consent shall not be unreasonably withheld), voluntarily make any payment with respect to any demands for appraisals of Dissenting Shares, offer to settle or settle any such demands or approve any withdrawal of any such demands.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF INTEGRA AND SUB

Integra and Sub, jointly and severally, hereby represent and warrant to Prairie that:

Section 3.1 Corporate Organization. Integra is a corporation duly organized and validly existing under the laws of the State of Indiana and is duly qualified to do business as a foreign corporation in each jurisdiction in which its ownership or lease of property or the nature of the business conducted by it makes such qualification necessary, except for such jurisdictions in which the failure to be so qualified would not have a Material Adverse Effect (as defined in Section 8.6(a)(vii)). Integra is registered as a bank holding company under the BHCA. Integra has the requisite corporate power and authority to own, lease and operate its properties and assets and to carry on its business as it is now being conducted. Integra has heretofore delivered to Prairie true and complete copies of its Articles of Incorporation and By-laws as currently in effect. Sub is duly organized, validly existing and in good standing under the laws of the State of Delaware and is duly qualified to do business as a foreign corporation in Illinois.

Section 3.2 Authority. Each of Integra and Sub has the requisite corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated by this Agreement. The execution and delivery of this Agreement and the consummation of the transactions contemplated herein have been duly approved by the Boards of Directors of Integra and Sub and no other corporate or shareholder proceedings on the part of Integra or Sub are necessary to authorize this Agreement or to consummate the transactions so contemplated. This Agreement has been duly executed and delivered by, and constitutes valid and binding obligations of, Integra and Sub enforceable against Integra and Sub in accordance with its terms, except as enforceability thereof may be limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other similar laws affecting the enforcement of creditors’ rights generally and except that the availability of the equitable remedy

of specific performance or injunctive relief is subject to the discretion of the court before which any proceedings may be brought.

Except as set forth in the Prairie Disclosure Letter, Prairie and each Prairie Subsidiary have prepared in good faith and duly and timely filed, or caused to be duly and timely filed, Tax Returns required to be filed by them on or before the date hereof, except to the extent that all such failures to file, taken together, would not have a Material Adverse Effect. Except as set forth in the Prairie Disclosure Letter, Prairie and each Prairie Subsidiary have paid, or have made adequate provision or set up an adequate accrual or reserve for the payment of, all Taxes shown or required to be shown to be owing on all such Tax Returns, together with any interest, additions or penalties related to any such Taxes or to any open taxable year or period.

A valid S election or similar election has been in effect with respect to Prairie during the S Period in all relevant state and local jurisdictions in which Prairie is subject to Tax and in which such election is required.

officers or employees of Prairie or Prairie Subsidiaries (“Prairie Employee Plans”) have been maintained, operated, and administered in substantial compliance with their terms and currently comply, and have at all relevant times complied, in all material respects with the applicable requirements of the Employee Retirement Income Security Act of 1934, as amended (“ERISA”), the Code, and any other applicable laws. Except as set forth in the Prairie Disclosure Letter, with respect to each Prairie Employee Plan which is a pension plan (as defined in Section 3(2) of ERISA), each pension plan as amended (and any trust relating thereto) intended to be a qualified plan under Section 401(a) of the Code either (a) has been determined by the Internal Revenue Service (“IRS”) to be so qualified, (b) is the subject of a pending application for such determination that was timely filed, or (c) may still be submitted for such determination as an on-cycle filing under Revenue Procedure 2005-66. None of Prairie, any of the Prairie Subsidiaries, or any entity considered one employer with any of them under Section 4001 of ERISA or Section 414 of the Code has ever established or maintained a pension plan subject to Title IV of ERISA or has ever been a participating employer in a “multiemployer plan” within the meaning of Section 3(37) of ERISA or a “multiple employer plan” within the meaning of Section 413(c) of the Code. Each Prairie Employee Plan subject to Section 409A of the Code has been operated in good faith compliance with Code Section 409A since January 1, 2005. There is no basis for any person to assert that Prairie or any of the Prairie subsidiaries has an obligation to institute any employee plan or any such other arrangement, agreement or plan. Except as set forth in the Prairie Disclosure Letter, neither Prairie nor a Prairie Subsidiary was or has used any insurance policy to provide funding for a Prairie Employee Plan. Except as set forth in the Prairie Disclosure Letter, neither the execution of this Agreement, nor the consummation of the transactions contemplated thereby will (A) constitute a stated triggering event under any Prairie Employee Plan that will result in any payment (whether pay or otherwise) becoming due from Prairie or any of the Prairie Subsidiaries to any present or former officer, employee, director, stockholder, consultant or dependent of any of the foregoing or (B) accelerate the time of payment or vesting, or increase the amount of compensation due, to any present or former officer, employee, director, stockholder, consultant, or dependent of any of the foregoing. Neither Prairie nor any of the Prairie Subsidiaries has any obligations for retiree health or life insurance benefits under any Prairie Employee Plan, except as set forth in the Prairie Disclosure Letter. Except as set forth in the Prairie Disclosure Letter, there are no restrictions on the rights of Prairie or any of the Prairie Subsidiaries to amend or terminate any such Prairie Employee Plan without incurring any liability thereunder.

Section 4.10 Material Contracts. Except as set forth in the Prairie Disclosure Letter or disclosed in the Prairie Financial Statements, neither Prairie nor any Prairie Subsidiary is a party to, or is bound or affected by, or receives benefits under (a) any employment, severance, termination, consulting or retirement agreement (collectively, “Benefit Agreements”) providing for aggregate payments to any person in any calendar year in excess of $50,000, (b) any material agreement, indenture or other instrument relating to the borrowing of money by Prairie or any Prairie Subsidiary or the guarantee by Prairie or any Prairie Subsidiary of any such obligation (other than trade payables and instruments relating to transactions entered into in the ordinary course of business) or (c) any other contract or agreement or amendment thereto that, if Prairie Common Stock was registered under the Exchange Act, would be required to be filed as an exhibit to a Form 10-K or (after August 23, 2004) a Form 8-K filed with the Commission as of the date of this Agreement (collectively, the “Prairie Contracts”). Neither Prairie nor any Prairie

Subsidiary is in default under any Prairie Contract, which default is reasonably likely to have, either individually or in the aggregate, a Material Adverse Effect, and there has not occurred any event that with the lapse of time or the giving of notice or both would constitute such a default.

Section 4.11 Absence of Certain Changes or Events. Except as set forth in the Prairie Disclosure Letter or disclosed in the Prairie Financial Statements, since December 31, 2005 there has not been any change in the financial condition, results of operations or business of Prairie or any Prairie Subsidiary which has had or will have a Material Adverse Effect.

Section 4.12 Litigation. Except as disclosed in the Prairie Disclosure Letter, there is no suit, action or proceeding pending, or, to the Knowledge of Prairie, threatened against or affecting Prairie or any Prairie Subsidiary which, if determined adversely to Prairie, would be reasonably expected to have a Material Adverse Effect, nor is there any judgment, decree, injunction, rule or order of any Governmental Entity or arbitrator, outstanding against Prairie or any Prairie Subsidiary having, or which would reasonably be expected to have, a Material Adverse Effect on the business of Prairie and the Prairie Subsidiaries. Since January 1, 2001, Prairie and Prairie Bank have continuously maintained fidelity bonds insuring them against acts of dishonesty in such amounts as are customary, usual and prudent for organizations of their size and business. To the Knowledge of Prairie and Prairie Bank, there are no facts which would form the basis of a claim or claims under such bonds. Neither Prairie nor Prairie Bank has reason to believe that its respective fidelity coverage would not be renewed by the carrier on substantially the same terms as the existing coverage, except for possible premium increases unrelated to Prairie’s and the Prairie Subsidiaries’ past claim experience.

or to such other address as any party may have furnished to the other parties in writing in accordance with this Section 8.7.

Section 8.8 Counterparts. This Agreement may be executed in any number of counterparts, each of which will be deemed to be an original but all of which together will constitute but one agreement.

Section 8.9 Parties in Interest; Assignment. Except for Sections 2.1 through 2.4 above (which are intended to be for the benefit of the stockholders of Prairie and holders of Unexercised Options to the extent contemplated thereby and their beneficiaries, and may be enforced by such persons) and Sections 5.4 and 5.8 hereof (which are intended to be for the benefit of directors, officers or employees to the extent contemplated thereby and their beneficiaries, and may be enforced by such persons), this Agreement is not intended to nor will it confer upon any other person (other than the parties hereto) any rights or remedies. Except as herein expressly provided, without the prior written consent of the other parties to this Agreement no party shall assign any rights or delegate any obligations under this Agreement. Any such purported assignment or delegation made without prior consent of the other parties hereto shall be null and void.

Section 8.10 Effect of Termination; Expenses and Fees.

(a) In the event of termination of this Agreement by either Integra or Prairie as provided in Section 8.1 hereof, this Agreement shall forthwith become void and have no effect except as set forth in this Section 8.10, Section 8.5 and the last two sentences of Section 5.5, which shall survive any termination of this Agreement.

(b) If this Agreement is terminated by:

(i) Integra because: (A) Prairie committed a breach of its covenants or agreements under this Agreement (but not a breach of its representations or warranties); or (B) there is a breach of Prairie’s representations or warranties as of the Agreement Date, unless, in either case, such breach is a result of the failure by Integra to perform and comply in all material respects with any of its material obligations under this Agreement which are to be performed or complied with by it prior to or on the date required hereunder, or such breach or breaches, individually or in the aggregate, which does not result or would not result in a Material Adverse Effect on Prairie (in each case described in clauses (A) or (B), a “Prairie Breach Termination”); or

(ii) Integra because Prairie’s stockholders fail to approve this Agreement on or before March 31, 2007 and such failure was not a result of any action or inaction on the part of Integra (a “Prairie Stockholder Termination”);

and provided in the case of both clauses (i) and (ii), Integra is in material compliance with all of its material obligations under this Agreement, then in the event of a Prairie Breach Termination, Prairie shall pay to Integra, upon its written demand, an amount equal to the sum of Integra’s reasonable expenses incurred in connection with this Agreement and the transactions contemplated herein (the “Integra Expenses”), but not in excess of two hundred thousand dollars ($200,000), plus an amount equal to one million dollars ($1,000,000), and in the event of a Prairie Stockholder Termination, Prairie shall pay to Integra, upon its written demand, an amount equal to the sum of Integra’s Expenses, but not in excess of two hundred thousand Dollars ($200,000).

(c) In addition to any payments described in Section (b), if there is a Prairie Breach Termination or a Prairie Stockholder Termination, and within eighteen (18) months after such termination of this Agreement Prairie enters into an agreement, contract, letter of intent or understanding with any party other than Integra providing for the acquisition of control of Prairie or Prairie Bank by such other party, then:

(i) if the prior termination of this Agreement was a Prairie Breach Termination, Prairie shall pay to Integra, upon its written demand, the additional sum of three million eight hundred thousand dollars ($3,800,000); or

(ii) if the prior termination of this Agreement was a Prairie Stockholder Termination, Prairie shall pay to Integra, upon its written demand, the additional sum of four million eight hundred thousand dollars ($4,800,000);

provided, however, that in each such case, the provisions of this Section 8.10 shall in no way limit Integra’s rights against any such third party.

For purposes of this Section 8.10, the phrase “control of Prairie or Prairie Bank” means the acquisition by any such third party of: (x) legal or beneficial ownership (as defined by Rule 13d-3 promulgated under the Exchange Act) of greater than twenty percent (20%) of the then issued and outstanding voting stock of Prairie or Prairie Bank through any transaction to which Prairie, Prairie Bank or any Affiliate of Prairie or Prairie Bank is a party (other than by transfers among or between members of a family, caused by redemptions or repurchases of Prairie capital stock by Prairie or by issuance of shares of Prairie Common Stock or other securities to holders of record of Prairie Common Stock as of the date hereof); or (y) all or substantially all of the assets of Prairie or Prairie Bank (except transfers to an Affiliate of Prairie or Prairie Bank).

(d) If this Agreement is terminated by Integra pursuant to Section 8.1(f)(i), (ii) or (iii) after a Competing Transaction has been publicly announced or otherwise communicated or made known to the senior management of Prairie or the Prairie Board of Directors at any time after the date of this Agreement and prior to the taking of the vote of the stockholders of Prairie contemplated by this Agreement at the Prairie Stockholders Meeting, then Prairie shall pay to Integra, upon its written demand, by wire transfer of immediately available funds to an account designated by Integra, the sum of four million eight hundred thousand dollars ($4,800,000), plus an amount equal to the sum of Integra’s Expenses, but not in excess of two hundred thousand dollars ($200,000).

(e) If this Agreement is terminated by Integra pursuant to Section 8.1(f)(iv) after a Competing Transaction has been publicly announced or otherwise communicated or made known to the senior management of Prairie or the Prairie Board of Directors at any time after the date of this Agreement and prior to the taking of the vote of the stockholders of Prairie contemplated by this Agreement at the Prairie Stockholders Meeting, and subsequently, the stockholders of Prairie do not approve the Merger at the Prairie Stockholders Meeting or any adjournment thereof as contemplated hereunder, then Prairie shall

pay to Integra, upon its written demand, by wire transfer of immediately available funds to an amount designated by Integra, the sum of four million eight hundred thousand dollars ($4,800,000), plus an amount equal to the sum of Integra’s Expenses, but not in excess of two hundred thousand dollars ($200,000).

(f) The sums payable by Prairie under this Sections 8.10(b), (c), (d) and (e) shall be made by wire transfer of immediately available funds to an account designated by Integra and shall constitute liquidated damages and Integra’s receipt thereof shall be Integra’s sole and exclusive remedy under this Agreement for all breaches of this Agreement by Prairie or failure by its stockholders to approve this Agreement.

(g) If this Agreement is terminated by Prairie because (i) Integra committed a breach of its covenants or agreements under this Agreement (but not a breach of its representations or warranties); or (ii) there is a breach of Integra’s representations or warranties as of the Agreement Date, unless, in either case, such breach is a result of the failure by Prairie to perform and comply in all material respects with any of its material obligations under or on the date required hereunder, or such breach or breaches, individually or in the aggregate, do not result in or would not result in a Material Adverse Effect on Integra, then Prairie shall be entitled to recover any and all amounts and shall have any and all rights to which it may be entitled at law or in equity.

(h) If the Merger is consummated, all costs and expenses incurred in connection with this Agreement and the transactions contemplated hereby will be paid by the Surviving Corporation.

Section 8.11 Enforcement of the Agreement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties hereto will be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof.

Section 8.12 Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy, all other terms and provisions of this Agreement will nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner adverse to any party hereto. Upon any such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto will negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated by this Agreement are consummated to the extent possible.

Section 8.13 Update and Supplement to Disclosure Letters. Prairie and Integra shall be permitted to update and supplement their respective disclosure letters so as to disclose exceptions to one or more representations or warranties contained in Article III hereof in the case of Integra and Sub and Article IV hereof in the case of Prairie which are a result of events which

occur after the date hereof; provided, however, that, anything herein to the contrary notwithstanding, (a) no exceptions or other information set forth on any such updated or supplemented disclosure letter shall be deemed to cure any representation or warranty which was not true and correct as of the date of this Agreement, (b) the exceptions and other information set forth on any such updated or supplemented disclosure letter shall not be taken into consideration in determining, for purposes of this Agreement, whether the conditions set forth in Section 7.3 in the case of Integra and Sub, and Section 7.2 hereof in the case of Prairie shall have been satisfied, and (c) this Section 8.13 shall not relieve any party of its obligations under any covenant set forth herein.

Re:

Agreement and Plan of Merger, dated October , 2006 (the “Merger Agreement”), by and among Integra Bank Corporation (“Integra”), PFC Merger Corp. (“Sub”) and Prairie Financial Corporation (“Prairie”)

Gentlemen:

I have been advised that, as of the date hereof, I may be deemed to be an “affiliate” of Prairie, as that term is defined for purposes of paragraphs (c) and (d) of Rule 145 (“Rule 145”) of the Rules and Regulations of the Securities and Exchange Commission (the “Commission”) promulgated under the Securities Act of 1933, as amended (the “Securities Act”).

Pursuant to the terms and conditions of the Merger Agreement, each share of common stock of Prairie owned by me as of the effective time of the merger of Prairie with a subsidiary of Integra as contemplated by the Merger Agreement (the “Merger”) will be converted into the right to receive shares of common stock of Integra (“Shares”) and cash. This letter is delivered to Integra pursuant to Section 5.17 of the Merger Agreement.

1. I represent and warrant to Integra and agree that:

A. I shall not make any sale, transfer or other disposition of the Shares I receive pursuant to the Merger in violation of the Securities Act or the Rules and Regulations of the Commission promulgated thereunder.

B. I understand that the issuance of the Shares to me pursuant to the Merger shall be registered with the Commission under the Securities Act. I also understand that because I may be deemed an “affiliate” of Prairie and because any distributions by me of the Shares shall not be registered under the Securities Act, such Shares must be held by me unless (i) the sale, transfer or other distribution has been registered under the Securities Act, (ii) the sale, transfer or other distribution of such Shares is made in accordance with the provisions of Rule 145, or

B-1

(iii) in the opinion of counsel acceptable to Integra some other exemption from registration under the Securities Act is available with respect to any such proposed distribution, sale, transfer or other disposition of such Shares.

2. I understand and agree that:

A. Stop transfer instructions shall be issued with respect to the Shares and there shall be placed on the certificates representing such Shares, or any certificate delivered in substitution therefor, a legend stating in substance:

“The shares represented by this Certificate have been issued to an affiliate of a party to a transaction with Integra Bank Corporation pursuant to the provisions of Rule 145 under the Securities Act of 1933. A stop transfer order with respect to this Certificate has been issued to the Transfer Agent. The shares represented hereby will be transferred on the books of Integra Bank Corporation only upon delivery to the Transfer Agent of evidence, reasonably satisfactory to Integra Bank Corporation, that such transfer complies in all material respects with the provisions of the Securities Act of 1933 and the rules and regulations thereunder.”

B. Unless the transfer by me of Shares is a sale made in compliance with the provisions of Rule 145(d) or made pursuant to an effective registration statement under the Securities Act, Integra reserves the right to place the following legend on the Certificates issued to my transferee:

“The shares represented by this Certificate have not been registered under the Securities Act of 1933, as amended, and were acquired from a person who received such shares in a transaction to which Rule 145 under the Securities Act of 1933, as amended, applied. The shares have not been acquired by the holder with a view to, or for resale in connection with, any distribution thereof within the meaning of the Securities Act of 1933, as amended, and may not be sold or otherwise transferred unless the shares have been registered under the Securities Act of 1933, as amended, or an exemption from registration is available.”

I understand and agree that the legends set forth above shall be removed by delivery of substitute Certificates without any legend if I deliver to Integra a copy of a letter from the staff of the Commission, or an opinion of counsel in form and substance satisfactory to Integra, to the effect that no such legend is required for the purpose of the Securities Act.

B-2

I have carefully read this letter and the Merger Agreement and understand the requirements of each and the limitations imposed upon the distribution, sale, transfer or other disposition of Shares by me.

Very truly yours

B-3
