2 Item 5. Other Events. On July 10, 2000, M&T Bank Corporation announced that it had entered into a definitive agreement with Premier National Bancorp, Inc. ("Premier"), Lagrangeville, New York, pursuant to which Premier, a bank holding company, will be acquired by M&T Bank Corporation upon the satisfaction of a number of conditions. Upon consummation of the transaction, Premier National Bank, Premier's national bank subsidiary, will be merged into Manufacturers and Traders Trust Company ("M&T Bank"), M&T Bank Corporation's principal commercial bank subsidiary. Premier National Bank operates 34 banking offices in 7 counties in New York. At March 31, 2000, Premier reported approximately $1.6 billion in assets. Premier's common stock is registered pursuant to Section 12(g) of the Securities Exchange Act of 1934, as amended (File No. 1-13213). Additional information concerning Premier is on file with the Securities and Exchange Commission. Each share of Premier common stock outstanding at the time the Merger is consummated (the "Effective Time") will, at the election of the holder thereof, be converted into either that number of shares of common stock of M&T Bank Corporation (and cash in lieu of fractional shares) equal to the quotient of $21 divided by the Market Value (as defined below) of M&T Bank Corporation common stock, or the right to receive $21 in cash as provided in the Agreement and Plan of Merger, dated as of July 9, 2000, by and among Premier, M&T Bank Corporation, and M&T Bank Corporation's wholly owned subsidiary, Olympia Financial Corp. ("Olympia"), providing for the merger of Premier with and into Olympia (the "Plan of Merger"), set forth as Annex A to the Agreement and Plan of Reorganization (the "Reorganization Agreement" and, together with the Plan of Merger, the "Merger Agreements"), dated as of July 9, 2000, by and among M&T Bank Corporation, Premier and Olympia. The "Market Value" of M&T Bank Corporation common stock will be the average, for the 10 trading days immediately preceding the date on which the Effective Time occurs, of the daily average of the high and low prices of such stock on the New York Stock Exchange-Composite Transactions List (as reported by The Wall Street Journal or, if not reported therein, another comparable authoritative source). A copy of the Reorganization Agreement is filed as Exhibit 99.1 hereto and is incorporated herein by reference. Subject to possible adjustments set forth in the Plan of Merger, the total number of shares of Premier common stock to be exchanged for shares of common stock of M&T Bank Corporation shall be 50% of the approximately 15.8 million shares of Premier common stock outstanding on July 7, 2000. Premier shareholder elections to receive shares of common stock of M&T Bank Corporation or cash are subject to the allocation and proration procedures set forth in the Plan of Merger. Consummation of the transaction is subject to a number of conditions, including regulatory approvals and the approval of Premier's stockholders. Subject to the

3 satisfaction of all conditions, it is anticipated that the transaction will be completed in the first quarter of 2001. Following the consummation of the transaction, T. Jefferson Cunningham III, chairman and chief executive officer of Premier will be elected to the boards of directors of M&T Bank Corporation and M&T Bank, and will serve as chairman of M&T Bank's advisory board for the Hudson Valley region. Ten members of Premier's board also will join the regional advisory board. Contemporaneous with the execution and delivery of the definitive agreement described above, Premier granted M&T Bank Corporation a stock option (the "Stock Option") to acquire up to 19.9% of the outstanding shares of Premier common stock under certain conditions. A copy of the Stock Option Agreement, dated as of July 9, 2000, by and among M&T Bank Corporation and Premier granting the Stock Option is filed as Exhibit 99.2 hereto and is incorporated herein by reference. The press release issued by M&T Bank Corporation and Premier with respect to the announcement of the transaction described herein is filed as Exhibit 99.3 hereto and incorporated herein by reference. The press release contains forward-looking statements with respect to the financial condition, results of operations and business of M&T Bank Corporation and, assuming the consummation of the merger, a combined M&T Bank Corporation/Premier, including statements relating to the cost savings and accretion to reported earnings that will be realized from the merger. These forward-looking statements involve certain risks and uncertainties. Factors that may cause actual results to differ materially from those contemplated by such forward-looking statements include, among others, the following possibilities: (1) expected cost savings from the merger cannot be fully realized or realized within the expected time frame; (2) competitive pressure among depository institutions increases significantly; (3) costs or difficulties related to the integration of the business of M&T Bank Corporation and Premier are greater than expected; (4) changes in the interest rate environment reduce interest margins; (5) generally economic conditions, either nationally or in the states in which the combined company will be doing business, are less favorable than expected; or (6) legislation or regulatory requirements or changes adversely affect the business in which the combined company would be engaged. The foregoing descriptions of and references to all of the above-mentioned agreements and documents are qualified in their entirety by reference to the complete texts of the agreements and documents that are filed herewith and incorporated herein by reference.

Full payment has been made, or will be made in accordance with Section 404(a)(6) of the Code of all amounts that Purchaser or any ERISA Affiliate is required to pay under Section 412 of the Code or under the terms of the Purchaser Plans, and no accumulated funding deficiency (within the meaning of Section 412 of the Code) exists with respect to any Purchaser Plan. 3.11. LEGAL PROCEEDINGS There are no actions, suits or proceedings instituted, pending or, to the knowledge of Purchaser and Merger Sub, threatened against Purchaser, Merger Sub or any Purchaser Subsidiary or against any asset, interest or right of Purchaser or any Purchaser Subsidiary which could reasonably be expected to, individually or in the aggregate, have a Material Adverse Effect on Purchaser. There are no actual or, to the knowledge of Purchaser or any Purchaser Subsidiary, threatened actions, suits or proceedings which present a claim to restrain or prohibit the transactions contemplated herein or to impose any material liability in connection therewith which could reasonably be expected to, individually or in the aggregate, have a Material Adverse Effect on Purchaser. 3.12. COMPLIANCE WITH LAWS Except as Previously Disclosed, each of Purchaser and the Purchaser Subsidiaries is in compliance in all material respects with all statutes and regulations applicable to the conduct of its business, and none of them has received notification from any agency or department of federal, state or local government (i) asserting a material violation of any such statute or regulation, (ii) threatening to revoke any license, franchise, permit or government authorization or (iii) restricting or in any way limiting its operations, except for such noncompliance, violations, revocations, limitations and restrictions which would not, individually or in the aggregate, have a Material Adverse Effect on Purchaser. None of Purchaser or any Purchaser Subsidiary is subject to any regulatory or supervisory cease and desist order, agreement, directive, memorandum of understanding or commitment which could be reasonably anticipated to have a Material Adverse Effect on Purchaser, and none of them has received any communication requesting that they enter into any of the foregoing. 3.13. TAX MATTERS (a) Purchaser and each Purchaser Subsidiary have timely filed, or have timely requested filing extensions for, federal income tax returns for each year through December 31, 1998 and have timely filed, or caused to be filed, or have timely requested filing extensions for, all other Tax Returns required to be filed with respect to Purchaser or any Purchaser Subsidiary, except where the failure to file timely such federal income and other Tax Returns would not, in the aggregate, have a Material Adverse Effect on Purchaser. All Taxes due by or on behalf of Purchaser or any Purchaser Subsidiary have been paid or adequate reserves have been established on the Purchaser Financial Statements for the payment of such Taxes, except where any such failure to pay or establish adequate reserves would not, in the aggregate, have a Material Adverse Effect on Purchaser. Neither Purchaser nor any Purchaser Subsidiary will have any material liability for any such Taxes in excess of the amounts so paid or reserves or accruals so established except where such liability would not have a Material Adverse Effect on Purchaser. - 22 -

23 (b) All Tax Returns filed by Purchaser and each Purchaser Subsidiary are complete and accurate in all material respects. Neither Purchaser nor any Purchaser Subsidiary is delinquent in the payment of any material Tax, and, except as Previously Disclosed, none of them has requested any extension of time within which to file any Tax Returns which have not since been filed. Except as Previously Disclosed or as fully settled and paid or accrued on the Purchaser Financial Statements, to Purchaser's knowledge, no material audit examination, deficiency, adjustment, refund claim or litigation with respect to Tax Returns, paid Taxes, unpaid Taxes or Tax attributes of Purchaser or any Purchaser Subsidiary has been proposed, asserted or assessed (tentatively or otherwise). (c) Neither Purchaser nor any Purchaser Subsidiary is a party to any agreement (other than an agreement exclusively among Purchaser and the Purchaser Subsidiaries) providing for the allocation or sharing of, or indemnification for, Taxes. (d) Neither Purchaser nor any Purchaser Subsidiary is required to include in income any adjustment in any taxable period ending after the date hereof pursuant to Section 481(a) of the Code other than any adjustment for which it already has made an accrual. (e) Neither Purchaser nor any Purchaser Subsidiary has executed or entered into any written agreement with any Tax authority conceding or agreeing to any treatment of Taxes or Tax attributes, including, without limitation, Internal Revenue Service Form 870 or Form 870-AD, closing agreement or special closing agreement, affecting the Purchaser or any Purchaser Subsidiary pursuant to Section 7121 of the Code or any predecessor provision thereof or any similar provision of state, local or foreign law, which agreement would have a Material Adverse Effect on Purchaser or any Purchaser Subsidiary. (f) For purposes of this Section 3.13 and Section 3.19, (i) references to Purchaser and any Purchaser Subsidiary shall include predecessors thereof and (ii) "Purchaser Subsidiary" shall include each Subsidiary (as defined in Article 1 hereof) of Purchaser, and each corporation, partnership, limited liability company, joint venture or other entity which Purchaser controls directly or indirectly (through one or more intermediaries). For purposes of the previous sentence, "control" means the possession, direct or indirect, of the power either (1) to vote fifty percent (50%) or more of the voting interests of a corporation, partnership, limited liability company, joint venture or other entity, or (2) to direct or cause the direction of the management and policies of a corporation, partnership, limited liability company, joint venture or other entity, whether by contract or otherwise. 3.14.

24 3.15. INSURANCE Purchaser and the Purchaser Subsidiaries each currently maintains insurance in amounts considered by Purchaser and any Purchaser Subsidiary as applicable, to be reasonably necessary for their operations. Neither Purchaser nor any Purchaser Subsidiary has received any notice of a material premium increase or cancellation with respect to any of its insurance policies or bonds, and within the last three years, neither Purchaser nor any Purchaser Subsidiary has been refused any insurance coverage sought or applied for, and Purchaser has no reason to believe that existing insurance coverage cannot be renewed as and when the same shall expire, upon terms and conditions substantially as favorable as those presently in effect, other than possible increases in premiums or unavailability in coverage that have not resulted from any extraordinary loss experience of Purchaser or any Purchaser Subsidiary. 3.16. ENVIRONMENTAL LIABILITY Neither Purchaser nor any Purchaser Subsidiary has received any written notice of any legal, administrative, arbitral or other proceeding, claim or action and, to the knowledge of Purchaser and the Purchaser Subsidiaries, there is no governmental investigation of any nature ongoing, in each case that could reasonably be expected to result in the imposition, on Purchaser or any Purchaser Subsidiary of any liability arising under any local, state or federal environmental statute, regulation or ordinance including, without limitation, the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, which liability would have a Material Adverse Effect on Purchaser; except as Previously Disclosed, there are no facts or circumstances known to Purchaser which could reasonably be expected to form the basis for any such proceeding, claim, action or governmental investigation that would impose any such liability; and neither Purchaser nor any Purchaser Subsidiary is subject to any agreement, order, judgment, decree or memorandum by or with any court, governmental authority, regulatory agency or third party imposing any such liability. 3.17. CERTAIN INFORMATION When the Registration Statement or any post-effective amendment thereto shall become effective, and at all times subsequent to such effectiveness up to and including the time of the Seller shareholders' meeting to vote upon the Merger, such Registration Statement and all amendments or supplements thereto, except with respect to all information set forth or incorporated by reference therein furnished by Seller relating to Seller and the Seller Subsidiaries, (i) shall comply in all material respects with the applicable provisions of the Securities Laws, and (ii) shall not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements contained therein not misleading. All information concerning Purchaser and its directors, officers, shareholders and any Subsidiaries included (or submitted for inclusion) in any application and furnished by it pursuant to Section 4.3 of this Agreement shall be true, correct and complete in all material respects. - 24 -

25 3.18. YEAR 2000 The computer software operated by Purchaser or any Purchaser Subsidiary which is material to the conduct of Purchaser's or any Purchaser Subsidiary's business is capable of providing uninterrupted millennium functionality to record, store, process and present calendar dates falling on or after January 1, 2000 in substantially the same manner and with the same functionality as such software records, stores, processes and presents such calendar dates falling on or before December 31, 1999, and such software and Purchaser or any Purchaser Subsidiary currently are otherwise in compliance with all relevant Regulatory Authority guidance and requirements relating to the Year 2000 computer issues including the statements of the Federal Financial Institutions Examination Council, dated May 5, 1997, entitled "Year 2000 Project Management Awareness," and December 1997, entitled "Safety and Soundness Guidelines Concerning the Year 2000 Business Risk." The costs of the adaptations referred to in this clause will not have a Material Adverse Effect on Purchaser. 3.19. TAX TREATMENT As of the date of this Agreement, Purchaser knows of no reason relating to it or any of the Purchaser Subsidiaries which would reasonably cause it to believe that the Merger will not qualify as a reorganization under Section 368(a) of the Code. 3.20. MERGER CONSIDERATION Purchaser will have, at the Effective Time, unissued shares of Common Stock and shares of Common Stock held in its treasury that are not reserved for any other purpose sufficient to provide the Stock Consideration and also will have available to it at the Effective Time funds sufficient to provide the Cash Consideration. ARTICLE 4. COVENANTS 4.1. SHAREHOLDERS' MEETING Seller shall submit this Reorganization Agreement and the Plan of Merger to its shareholders for approval at a special meeting to be held as soon as practicable. Subject to the fiduciary duties of the Board of Directors of Seller as determined after consultation with counsel, the Board of Directors of Seller shall recommend that the shareholders of Seller vote in favor of such approval. At such meeting, subject to the fiduciary or contractual duties of Purchaser with respect to shares of Seller Common Stock held in fiduciary accounts, Purchaser shall, and shall cause its Subsidiaries to, cause all shares of Seller Common Stock then owned by Purchaser or any such Subsidiary, if any, to be voted in favor of the adoption of this Reorganization Agreement and the Plan of Merger. 4.2. PROXY STATEMENT; REGISTRATION STATEMENT As promptly as practicable after the date hereof, Purchaser and Seller shall cooperate in the preparation of the Proxy Statement to be mailed to the shareholders of Seller in connection with this Agreement and the transactions contemplated hereby and to be filed by Purchaser as - 25 -

26 part of the Registration Statement. Purchaser and Seller shall cooperate in the preparation of the Registration Statement and shall file with the Commission the Registration Statement and cause the Registration Statement to become effective as promptly as practicable after the date hereof. Purchaser will advise Seller, promptly after it receives notice thereof, of the time when the Registration Statement or any post-effective amendment thereto has become effective or any supplement or amendment has been filed, of the issuance of any stop order, of the suspension of qualification of the Purchaser Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, or the initiation or threat of any proceeding for any such purpose, or of any comments or request by the SEC for the amendment or supplement of the Registration Statement or for additional information. If at any time prior to the Effective Time any event shall occur that should be set forth in an amendment of or a supplement to the Registration Statement or the Proxy Statement, Purchaser, Merger Sub and Seller shall cooperate with each other in the preparation of any amendment or supplement thereto, and each shall notify the other of the receipt of any comments of the SEC with respect to the Registration Statement or the Proxy Statement and of any requests by the SEC for any amendment or supplement thereto or for additional information, and shall provide to the other promptly copies of all correspondence between Purchaser or Seller, as the case may be, or any of its Representatives with respect to the Registration Statement or the Proxy Statement. Purchaser shall give Seller and its counsel the opportunity to review the Registration Statement and all responses to requests for additional information by and replies to comments of the SEC before their being filed with, or sent to, the SEC, and Purchaser shall prepare and file with the SEC such amendment or supplement as soon thereafter as is reasonably practicable. Each of Seller, Purchaser and Merger Sub agrees to use its best efforts, after consultation with the other parties hereto, to respond promptly to all such comments of and requests by the SEC and to cause (x) the Registration Statement to be declared effective by the SEC at the earliest practicable time and to be kept effective as long as is necessary to consummate the Merger, and (y) the Proxy Statement to be mailed to the holders of Seller Common Stock entitled to vote at the meeting of the stockholders of Seller at the earliest practicable time. Purchaser shall take all actions necessary to register or qualify the shares of Purchaser Common Stock to be issued in the Merger pursuant to all applicable state "blue sky" or securities laws and shall maintain such registrations or qualifications in effect for all purposes hereof. Purchaser shall apply for, and shall use reasonable best efforts to obtain, approval to list the shares of Purchaser Common Stock to be issued in the Merger on the NYSE, subject to official notice of issuance, prior to the Effective Date. 4.3. APPLICATIONS As promptly as practicable after the date hereof, and after a reasonable opportunity for review by counsel to Seller, Purchaser shall submit any requisite applications for prior approval of, and notices with respect to, the transactions contemplated herein, in the Plan of Merger and in the Bank Merger Agreement, to (i) the Federal Reserve Board pursuant to Sections 3 and 4 of the Bank Holding Company Act and the Bank Merger Act, (ii) the New York Banking Board pursuant to Section 142 of the New York Banking Law, and (iii) the OCC pursuant to 12 C.F.R. Section 5.33(g)(3), and each of the parties hereto shall, and they shall cause their respective subsidiaries to, submit any applications, notices or other filings to any other state or federal government agency, department or body the approval of which is required for consummation of the Merger and the Bank Merger. Seller and Purchaser each represents and warrants to the other that all information concerning it and its directors, officers, shareholders and subsidiaries - 26 -

27 included (or submitted for inclusion) in any such application and furnished by it shall be true, correct and complete in all material respects. Purchaser will provide all information and communications requested by the applicable governmental or regulatory authorities, and Purchaser will proceed diligently and in good faith to obtain the requisite regulatory approvals. 4.4. BEST EFFORTS (a) Subject to the terms and conditions of this Agreement, Purchaser, Merger Sub, and Seller shall each use its reasonable best efforts in good faith, and each of them shall cause its Subsidiaries to use their reasonable best efforts in good faith, to (i) furnish such information as may be required in connection with the preparation of the documents referred to in Sections 4.2 and 4.3 above, and (ii) take or cause to be taken all action necessary or desirable on its part so as to permit consummation of the Merger on or at the earliest possible date, including, without limitation, (1) obtaining the consent or approval of each individual, partnership, corporation, association or other business or professional entity whose consent or approval is required for consummation of the transactions contemplated hereby, provided that neither Seller nor any Seller Subsidiary shall agree to make any payments or modifications to agreements in connection therewith without the prior written consent of Purchaser, which consent shall not be unreasonably withheld and (2) requesting the delivery of appropriate opinions, consents and letters from its counsel and independent auditors. Subject to the terms and conditions of this Agreement, no party hereto shall take or fail to take, or cause or permit its Subsidiaries to take or fail to take, or to the best of its ability permit to be taken or omitted to be taken by any third persons, any action that would substantially impair the prospects of completing the Merger pursuant to this Reorganization Agreement and the Plan of Merger, that would materially delay such completion, or that would adversely affect the qualification of the Merger as a reorganization within the meaning of Section 368(a) of the Code; provided that nothing herein contained shall preclude Purchaser from exercising its rights under the Option Agreement. In the event that either party has taken any action, whether before, on or after the date hereof, that would adversely affect such qualification, each party shall take such action as the other party may reasonably request to cure such effect to the extent curable without a Material Adverse Effect on either of the parties. (b) Unless prohibited by applicable law, Seller shall give prompt notice to Purchaser, and Purchaser shall give prompt notice to Seller, of (i) the occurrence, or failure to occur, of any event known to it which occurrence or failure would be reasonably likely to cause any representation or warranty contained in this Agreement to be untrue or inaccurate at any time from the date hereof to the Closing Date such that the condition set forth in Section 5.2(a) or 5.3(a), as applicable, would not be met if such failure to be true or accurate were to occur or be continuing on the Closing Date, and (ii) any material failure of Seller or Purchaser known to Seller or Purchaser, as the case may be, to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder, and each party shall use all reasonable best efforts to remedy such failure. (c) From the date of this Agreement through the Effective Date, to the extent permitted by law, Seller shall, and shall cause the Seller Subsidiaries to, provide such assistance to Purchaser at Purchaser's expense and as it shall reasonably request to assist Purchaser in converting and transferring as soon as practicable after the Effective Date all information - 27 -

28 concerning the loans, deposits and other assets and liabilities of Seller and the Seller Subsidiaries into Purchaser's own data processing system, with a view to facilitating the integration of Purchaser's and Seller's systems and otherwise combining Purchaser's and Seller's operations upon consummation of the Merger; provided, however, that neither Seller nor any Seller Subsidiary shall be required to take any action pursuant to this sentence that would interfere unreasonably with the ongoing operations of Seller or such Seller Subsidiary. After execution of this Agreement, to the extent permitted by law and contracts to which they are a party, Seller shall provide Purchaser with computer file instructions with respect to the information in its data processing system regarding the assets and liabilities of Seller and the Seller Subsidiaries, together with operational procedures designed to implement the transfer of such information to Purchaser, with a view to facilitating the integration of Purchaser's and Seller's systems and otherwise combining Purchaser's and Seller's operations upon consummation of the Merger. After execution of this Agreement, Seller and Purchaser shall each designate an individual to serve as liaison concerning the transfer of data processing information and other similar operational matters and to consult as to whether and when Seller will proceed with its pending data processing conversion. (d) In the event that this Agreement is terminated without the transactions contemplated hereby having been consummated, upon the request of Seller, Purchaser will and will cause its representatives to promptly redeliver or cause to be redelivered, or, at its sole discretion, destroy or caused to be destroyed, all copies of documents and information furnished by Seller, as the case may be, or its representatives to such party and its representatives in connection with this Agreement or the transactions contemplated hereby and destroy or cause to be destroyed all notes, memoranda, summaries, analyses, compilations and other writings related thereto or based thereon prepared by Purchaser or its representatives. (e) Each party shall provide and shall request its auditors to provide the other party with such historical financial information regarding it (and related audit reports and consents) as the other party may reasonably request for disclosure purposes under the Securities Laws. 4.5. INVESTIGATION AND CONFIDENTIALITY Seller and Purchaser each will keep the other advised of all material developments relevant to its business and to consummation of the transactions contemplated herein and in the Plan of Merger. Purchaser and Seller each may make or cause to be made such investigation of the financial and legal condition of the other as such party reasonably deems necessary or advisable in connection with the transactions contemplated herein and in the Plan of Merger, provided, however, that such investigation shall be conducted during normal business hours on reasonable notice and shall be reasonably related to such transactions and shall not interfere unnecessarily with normal operations. Purchaser and Seller agree to furnish the other and the other's advisors with such financial data and other information with respect to its business and properties as such other party shall from time to time reasonably request. No investigation pursuant to this Section 4.5 shall affect or be deemed to modify any representation or warranty made by, or the conditions to the obligations to consummate the Merger of, any party hereto. Each party hereto shall hold all information furnished by the other party or any of such party's Subsidiaries or representatives pursuant to this Agreement in confidence to the extent required - 28 -

29 by, and in accordance with, the provisions of the confidentiality agreement, dated June 14, 2000, between Seller and Purchaser (the "Confidentiality Agreement"). 4.6. PRESS RELEASES Seller and Purchaser shall agree with each other as to the form and substance of any press release related to this Reorganization Agreement and the Plan of Merger or the transactions contemplated hereby or thereby, and shall consult each other as to the form and substance of other public disclosures related thereto, provided, however, that nothing contained herein shall prohibit any party, following notification to the other parties, from making any disclosure which is required by applicable law or NYSE or Amex rules. 4.7. ACTIONS PENDING THE MERGER (a) Prior to the Closing Date, and except as otherwise provided for by this Reorganization Agreement, the Plan of Merger, the Option Agreement, or consented to or approved by the other party hereto, each of Purchaser and Seller shall, and shall cause each of its Subsidiaries to, use its reasonable best efforts to preserve in all material respects its properties, business and relationships with customers, employees and other persons.

(11) change its lending, investment, asset/liability management or other material banking policies in any material respect except as may be required by applicable law, regulation or order; (12) change its methods of accounting in effect at December 31, 1999, except as required by changes in generally accepted accounting principles concurred in by its independent certified public accountants, or change any of its methods of reporting income, deductions or other items for federal income tax purposes from those employed in the preparation of its federal income tax returns for the year ended December 31, 1999, except as required by applicable law; (13) authorize or permit any of its officers, directors, employees or agents to directly or indirectly solicit, initiate or encourage any inquiries relating to, or the making of any proposal which constitutes, a "Takeover Proposal" (as defined below), or, except to the extent its Board of Directors determines to be legally required for the discharge of its fiduciary duties, (i) recommend or endorse any Takeover Proposal, (ii) participate in any discussions or negotiations, (iii) provide third parties with any nonpublic information, relating to any such inquiry or proposal, - 30 -

31 or (iv) otherwise facilitate any effort or attempt to make or implement a Takeover Proposal; provided, however, that Seller may communicate information about any such Takeover Proposal to its shareholders if, in the judgment of Seller's Board of Directors, after consultation with outside counsel, such communication is necessary in order to comply with its fiduciary duties to Seller's shareholders required under applicable law. Seller will take all actions necessary or advisable to inform the appropriate individuals or entities referred to in the first sentence hereof of the obligations undertaken herein. Seller will notify Purchaser immediately if any such inquiries or Takeover Proposals are received by, any such information is requested from, or any such negotiations or discussions are sought to be initiated or continued with, Seller, and Seller will promptly inform Purchaser in writing of all of the relevant details with respect to the foregoing. As used in this Agreement, "Takeover Proposal" shall mean any tender or exchange offer, proposal for a merger, consolidation or other business combination involving Seller or any Seller Subsidiary or any proposal or offer to acquire in any manner a substantial equity interest in, or a substantial portion of the assets of, Seller or any Seller Subsidiary other than the transactions contemplated or permitted by this Agreement, the Plan of Merger and the Option Agreement; or (14) agree to do any of the foregoing. (c) Purchaser shall not, and shall not permit any of the Purchaser Subsidiaries to, except with the prior written consent of Seller or as expressly contemplated or permitted by this Agreement, the Plan of Merger or the Option Agreement, carry on its business other than in the usual, regular and ordinary course in substantially the same manner as heretofore conducted.

CLOSING; ARTICLES OF MERGER The transactions contemplated by this Reorganization Agreement and the Plan of Merger shall be consummated at a closing to be held at the offices of the law firm of Arnold & Porter, 399 Park Avenue, New York, New York on a date between January 2, 2001 and February 15, 2001 - 31 -

32 determined by the Purchaser with 5 days prior notice to Seller, or if later, the first business day following satisfaction of the conditions to consummation of the Merger set forth in Article 5 hereof other than conditions to be satisfied at the Closing (such later date, the "Closing Date"). In connection with such Closing, Merger Sub and Seller shall execute a certificate of merger and shall cause such certificate to be delivered, as soon as practicable on the Closing Date, to (i) the Delaware Secretary of State in accordance with Section 251(c) of the Delaware General Corporation Law, and (ii) the New York Department of State in accordance with Section 904 of the New York Business Corporation Law. The Merger shall be effective at the time and on the date (the "Effective Date"), not later than two business days after the Closing Date, specified in such certificate of merger. 4.10. AFFILIATES Seller and Purchaser shall cooperate and use their best efforts to identify those persons who may be deemed to be "affiliates" of Seller within the meaning of Rule 145 promulgated by the Commission under the Securities Act. Seller shall use its reasonable best efforts to cause each person so identified to deliver to Purchaser, no later than 30 days prior to the Effective Date, a written Affiliate Agreement in the form attached hereto as Exhibit A. 4.11. SELLER EMPLOYEES; DIRECTORS AND MANAGEMENT; INDEMNIFICATION (a) On and after the Effective Date (or as soon thereafter as may be practicable), all persons who are employed by Seller and/or any of the Seller Subsidiaries on such date ("Seller Employees") shall be employed on terms and conditions (including benefits) that in the aggregate are no less favorable (as determined by Purchaser in its reasonable discretion and good faith after consultation with Seller) with respect to their employment by Purchaser and its Subsidiaries after the Effective Date than those generally afforded to other similarly situated employees of Purchaser or its Subsidiaries, subject to the terms and conditions under which those employee benefits are made available to such employees and provided that (i) for purposes of (A) determining eligibility for and vesting of such employee benefits (and not for pension benefit accrual purposes), (B) determining levels of short-term disability benefits, vacation benefits and severance benefits under any severance pay arrangement (to the extent any such arrangement applies to employees generally and gives credit for length of service with Purchaser or a Purchaser Subsidiary), and (C) if applicable, satisfying any waiting periods concerning "preexisting conditions," service with Seller or a Seller Subsidiary or any predecessor thereto prior to the Effective Date shall be treated as service with an "employer" to the same extent as if such persons had been employees of Purchaser, and (ii) copayments and expenses paid by the Seller Employees prior to the Effective Date under the Seller Plans that provide medical benefits shall be treated as if paid under Purchaser's employee benefit plans that provide medical benefits for purposes of determining satisfaction of copayment and deductible requirements under such Purchaser plans, and provided, further, that this Section 4.11(a) shall not be construed (A) to limit the ability of Purchaser and its Subsidiaries to terminate the employment of any employee at any time for any reason or to review employee benefits programs from time to time and to make such changes as they deem appropriate or (B) to require Purchaser or its Subsidiaries to provide employees or former employees of Seller or any of its Subsidiaries with post-retirement medical benefits more favorable than those provided to new hires at Purchaser. Purchaser agrees to honor, or to cause the appropriate Purchaser Subsidiary - 32 -

33 to honor, in accordance with their terms all employment, severance and employee benefit plans, contracts, agreements and arrangements, and understandings Previously Disclosed, provided, however, that the foregoing shall not prevent Purchaser from amending or terminating any such plan, contract, or agreement in accordance with its terms and applicable law. The continued coverage of the Seller Employees under the employee benefit plans maintained by Seller and/or any Seller Subsidiary immediately prior to the Effective Date (the "Seller Plans") during a transition period of no more than 6 months shall be deemed to provide the Seller Employees with benefits that are no less favorable than those offered to other employees of Purchaser and any Purchaser Subsidiary; provided, that after the Effective Date there is no material reduction in the benefits provided under the Seller Plans. No provision of this Section 4.11(a) shall create any third party beneficiary rights in any employee or former employee of Seller (including any beneficiary or dependent thereof) in respect of continued employment (or resumed employment) or any other matter. (b) The Merger shall be deemed to constitute a "change in control" for purposes of each Seller Plan, employment, severance, consulting and change in control agreement that, as Previously Disclosed to Purchaser, contains "change in control" provisions. On and after the Effective Date, the individuals Previously Disclosed to Purchaser (the "Previously Disclosed Individuals") shall be deemed to have "good reason" or to have experienced a "triggering event" as the case may be under their respective employment agreements with Seller, all as Previously Disclosed to Purchaser. (c) Prior to the Effective Date, Seller shall take all actions that may be requested by Purchaser in writing upon advance notice of not less than 45 days with respect to (i) causing one or more Seller Plans to terminate as of the Effective Date or for benefit accrual and entitlements to cease as of the Effective Date, (ii) causing the continuation on and after the Effective Date of any contract, arrangement or insurance policy relating to any Seller Plan for such period as may be requested by Purchaser, or (iii) cooperating with Purchaser to facilitate the merger of any Seller Plan into any Purchaser Plan on or following the Effective Date. ; provided, however, that with respect to any such action: (1) Purchaser shall, at Seller's request, reimburse Seller for reasonable out-of-pocket expenses incurred by Seller with respect to such action; (2) such action shall have no material effect on the Seller Plans prior to the Effective Date; (3) Seller shall not be required to take any action that would result in a breach of its obligations under this Agreement; and (4) Seller shall not be required to take any action that would result in a violation of the terms of any Seller Plan or of any applicable law or regulation. (d) Purchaser's Board of Directors shall take all requisite action to elect, as of the Effective Date, Mr. T. Jefferson Cunningham III as a director of Purchaser, and, subject to the Board's fiduciary duties, shall nominate Mr. Cunningham for re-election as a director of Purchaser for the next succeeding three years. (e) Purchaser shall cause Purchaser Bank's Board of Directors to take all requisite action to elect, as of the Effective Date, Mr. T. Jefferson Cunningham III as a director of Purchaser Bank, and shall cause the board of directors of Purchaser Bank, subject to the board's fiduciary duties, to nominate Mr. Cunningham for re-election as a director of Purchaser Bank for the next succeeding three years. - 33 -

34 (f) In the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, including, without limitation, any such claim, action, suit, proceeding or investigation in which any person who is now, or has been at any time prior to the date of this Agreement, or who becomes prior to the Effective Date, a director or officer of Seller (the "Indemnified Parties") is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he is or was a director, officer or employee of Seller, or any Seller Subsidiary or any of their respective predecessors or (ii) this Agreement, the Plan of Merger, the Option Agreement or any of the transactions contemplated hereby or thereby, whether in any case asserted or arising before or after the Effective Date, the parties hereto agree to cooperate and use their best efforts to defend against and respond thereto. On and after the Effective Date, Purchaser shall indemnify and hold harmless, as and to the fullest extent permitted by law, each such Indemnified Party against any losses, claims, damages, liabilities, costs, expenses (including reasonable attorney's fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by law upon receipt of any undertaking required by applicable law), judgments, fines and amounts paid in settlement in connection with any such threatened or actual claim, action, suit, proceeding or investigation, and in the event of any such threatened or actual claim, action, suit, proceeding or investigation (whether asserted or arising before or after the Effective Date), the Indemnified Parties may retain counsel reasonably satisfactory to them after consultation with Purchaser; provided, however, that (1) Purchaser shall have the right to assume the defense thereof and upon such assumption Purchaser shall not be liable to any Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if Purchaser elects not to assume such defense or counsel for the Indemnified Parties reasonably advises the Indemnified Parties that there are issues which raise conflicts of interest between Purchaser and the Indemnified Parties, the Indemnified Parties may retain counsel reasonably satisfactory to them after notification, and Purchaser shall pay the reasonable fees and expenses of such counsel for the Indemnified Parties, (2) Purchaser shall be obligated pursuant to this paragraph to pay for only one firm of counsel for all Indemnified Parties, (3) Purchaser shall not be liable for any settlement effected without its prior written consent (which consent shall not be unreasonably withheld), and (4) Purchaser shall have no obligation hereunder to any Indemnified Party when and if a court of competent jurisdiction shall ultimately determine, and such determination shall have become final and nonappealable, that indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable law. Any Indemnified Party wishing to claim Indemnification under this Section 4.11(f), upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Purchaser thereof, provided that the failure of any Indemnified Party to so notify Purchaser shall not relieve it of its obligations hereunder except (and only) to the extent that such failure materially prejudices Purchaser. (g) Purchaser agrees that all rights to indemnification and all limitations on liability existing in favor of the directors, officers and employees of Seller and any Seller Subsidiary (the "Covered Parties") as provided in their respective Certificates of Incorporation, Bylaws or similar governing documents as in effect as of the date of this Agreement with respect to matters occurring prior to the Effective Date shall survive the Merger and shall continue in full force and effect, and shall be honored by such entities or their respective successors as if they were the indemnifying party thereunder, without any amendment thereto, for a period of six - 34 -

35 years from the Effective Date; provided, however, that all rights to indemnification in respect of any claim ("Claim") asserted or made within such period shall continue until the final disposition of such Claim; provided, further, however, that nothing contained in this Section 4.11(g) shall be deemed to preclude the liquidation, consolidation or merger of Seller or any Seller Subsidiary, in which case all of such rights to indemnification and limitations on liability shall be deemed to so survive and continue as an obligation of Purchaser or the successor to Seller or the Seller Subsidiary notwithstanding any such liquidation, consolidation or merger. (h) Purchaser, from and after the Effective Date will use its reasonable best efforts directly or indirectly to cause the persons who served as directors or officers of Seller on or before the Effective Date to be covered by Seller's existing directors' and officers' liability insurance policy (provided that Purchaser may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are not less advantageous than such policy) but in no event shall any insured person be entitled under this Section 4.11(h) to insurance coverage more favorable than that provided to him or her in such capacities as of the date hereof with respect to acts or omissions resulting from their service as such on or prior to the Effective Date. Such insurance coverage, if available, shall commence on the Effective Date and will be provided for a period of no less than four years after the Effective Date; provided, however, that in no event shall Purchaser be required to expend more than 200% of the current amount expended by Seller (the "Insurance Amount") to maintain or procure insurance coverage pursuant hereto and, provided, further, that the Insurance Amount shall be deemed reasonable for purposes of this Section 4.11(h). Seller agrees to renew any such existing insurance or to purchase any "discovery period" insurance provided for thereunder at Purchaser's request. (i) In the event Purchaser or any of its successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger, or (ii) transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, to the extent necessary, proper provision shall be made so that the successors and assigns of Purchaser assume the obligations set forth in this section. (j) The provisions of Section 4.11(f), (g), (h) and (i) are intended to be for the benefit of, and shall be enforceable by, each Indemnified Party and their respective heirs and representatives and shall be in addition to the provisions regarding indemnification and insurance contained in the New York Business Corporation Law, in contracts or otherwise. 4.12. SELLER SUBSIDIARIES Seller undertakes and agrees that, if reasonably so requested by Purchaser, it shall take all necessary action to facilitate the merger of Seller Subsidiaries with Subsidiaries of Purchaser or the dissolution of such Seller Subsidiaries effective at or after the Effective Date; provided however, that in no event shall the Closing be delayed in order to facilitate any such merger or dissolution and provided, further, however, that Seller shall not be required to take any action that could adversely affect the qualification of the Merger as a reorganization within the meaning of Section 368(a) of the Code. - 35 -

36 4.13. VOTING AGREEMENTS Each director of Seller shall, within 30 days of the date hereof, enter into a voting agreement with Purchaser pursuant to which such director agrees to vote all shares of Seller Common Stock with respect to which such director shall have voting rights on the record date for the special meeting of Seller in favor of the Merger and further agrees not to dispose of any shares of Seller Common Stock he or she holds as of the date of such voting agreement prior to the close of business on such record date. 4.14. DIVIDENDS After the date of this Agreement, each of Purchaser and Seller shall coordinate with the other the declaration of any dividends in respect of Purchaser Common Stock and Seller Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties hereto that holders of Purchaser Common Stock or Seller Common Stock shall not receive two dividends, or fail to receive one dividend, for any single calendar quarter with respect to their shares of Purchaser Common Stock and/or Seller Common Stock and any shares of Purchaser Common Stock any such holder receives in exchange therefor in the Merger. Notwithstanding the foregoing limitation, the holders of Seller Common Stock shall be entitled to receive dividends at the current level on a pro rata basis for any period less than a calendar quarter up to the Effective Date, provided that in determining the amount of any special dividend on Seller Common Stock, Seller shall deduct the pro rata portion of any dividend in respect of Purchaser Common Stock for the same period at the current rate to be received by such holders with respect to such period, taking into account the expected Exchange Ratio. 4.15. ADVISORY BOARDS Promptly following the Effective Date, Purchaser shall cause (i) 10 members of Seller's Board of Directors, identified by Seller prior to the Effective Date and reasonably acceptable to Purchaser to become members of the Hudson Valley Advisory Board of Purchaser Bank (the "Advisory Board"), (ii) Mr. T. Jefferson Cunningham III to be elected Chairman of the Advisory Board and (iii) such members to be appointed or elected for a period of not less than 24 months after the Effective Date as members of the Advisory Board, the function of which is to advise Purchaser Bank on business conditions and opportunities in the Hudson Valley region and on such other matters as Purchaser Bank may reasonably or customarily request of such a Board. Each such advisory director shall be paid for such services a fee according to a fee schedule to be established by Purchaser; provided, however, that notwithstanding anything else in this Section 4.15, no fee shall be paid for meetings of the Advisory Board not actually attended; and Purchaser Bank shall have no obligation to continue the services of any member of the Advisory Board who acts in a manner detrimental to Purchaser Bank. 4.16. SECTION 16 Seller shall, reasonably promptly following the date hereof, provide to Purchaser a list of (a) the directors and officers (as such terms are used under Section 16 of the Exchange Act and the rules and regulations of the SEC thereunder) of Seller, (b) the number of shares of Purchaser Common Stock and options thereon expected to be received pursuant to the Merger, as - 36 -

37 appropriate, by each such officer or director on the Effective Date on account of shares of Seller Common Stock, and options thereon, reasonably expected to be held by such directors and officers immediately prior to the Effective Date and (c) a description of the material terms of such options. Prior to the Effective Date, (a) the Seller Board of Directors shall take such actions consistent with the SEC's interpretive guidance to approve the disposition of Seller Common Stock, and options thereon, by each director and officer of Seller for purposes of Rule 16b-3(e) such that the deemed "sale" of such Seller Common Stock and options thereon by such persons pursuant to the Merger shall be exempt from liability pursuant to Section 16(b) of the Exchange Act, and (b) the Purchaser Board of Directors shall take such action consistent with the SEC's interpretive guidance to approve the acquisition of Purchaser Common Stock by each director and officer of Purchaser for purposes of Rule 16b-3(d) under the Exchange Act such that the deemed "purchase" of such Purchaser Common Stock, and options thereon, by such persons pursuant to the Merger shall be exempt from liability pursuant to Section 16(b) of the Exchange Act. 4.17. TAKEOVER LAWS No party hereto shall take any action that would cause the transactions contemplated by this Reorganization Agreement, the Plan of Merger or the Option Agreement to be subject to the requirements imposed by any Takeover Law, and each of them shall take all necessary steps within its control to exempt (or ensure the continued exemption of) the transactions contemplated by this Reorganization Agreement, the Plan of Merger and the Option Agreement from, or if necessary challenge the validity or applicability of, any applicable Takeover Law, as now or hereafter in effect. ARTICLE 5. CONDITIONS PRECEDENT 5.1. CONDITIONS PRECEDENT TO OBLIGATIONS OF PURCHASER, MERGER SUB AND SELLER The respective obligations of the parties to effect the Merger shall be subject to satisfaction or waiver of the following conditions at or prior to the Closing Date: (a) The stockholder approval contemplated by Section 2.5 hereof, shall have been duly and validly taken; (b) The parties hereto shall have received all regulatory approvals required or mutually deemed necessary in connection with the transactions contemplated by this Reorganization Agreement, the Plan of Merger and the Bank Merger Agreement, all notice periods and waiting periods required after the granting of any such approvals shall have passed and all conditions contained in any such approval required to have been satisfied prior to consummation of such transactions shall have been satisfied, provided, however, that no such approval shall have imposed any condition or requirement that, in the reasonable opinion of the Board of Directors of Purchaser or Seller so materially and adversely affects the anticipated economic and business benefits to Purchaser or Seller, respectively, of the transactions contemplated by this Agreement as to render consummation of such transactions inadvisable; - 37 -

38 (c) The Registration Statement (including any post-effective amendment thereto) shall be effective under the Securities Act, and no proceeding shall be pending, or to the knowledge of Purchaser, threatened by the Commission to suspend the effectiveness of such Registration Statement, and Purchaser shall have received all state securities or "Blue Sky" permits or other authorizations, or confirmations as to the availability of an exemption from registration requirements as may be necessary; (d) To the extent that any lease, license, loan, financing agreement or other contract or agreement to which Seller or any Seller Subsidiary is a party requires the consent of or waiver from the other party thereto as a result of the transactions contemplated by this Agreement, such consent or waiver shall have been obtained, unless the failure to obtain such consents or waivers, individually or in the aggregate, would not have a Material Adverse Effect on Seller; (e) None of the parties hereto shall be subject to any order, decree or injunction of a court or agency of competent jurisdiction which enjoins or prohibits the consummation of the transactions contemplated by this Reorganization Agreement and the Plan of Merger; (f) The shares of Purchaser Common Stock that may be issued in the Merger shall have been approved for listing on the NYSE, subject to official notice of issuance; and (g) Purchaser shall have received an opinion of Arnold & Porter, and Seller shall have received an opinion from Milbank, Tweed, Hadley & McCloy LLP, in each case in form and substance reasonably satisfactory to Purchaser and Seller, as the case may be, dated as of the Effective Date, substantially to the effect that, on the basis of facts, representations and assumptions set forth or referred to in such opinion, the Merger will be treated for federal income tax purposes as a reorganization or part of a reorganization within the meaning of Section 368(a) of the Code, and that, provided the Merger is such a reorganization: (i) Seller, Purchaser and Merger Sub will each be a party to such reorganization within the meaning of Section 368(b) of the Code; (ii) No gain or loss will be recognized by Purchaser, Merger Sub or Seller as a result of the Merger (except for amounts resulting from any required change in accounting methods, any income and deferred gain recognized pursuant to Treasury regulations issued under Section 1502 of the Code, or other exceptions as set forth in such opinion); (iii) No gain or loss will be recognized by Seller shareholders with respect to shares of Purchaser Common Stock received in exchange for all of their shares of Seller Common Stock; (iv) The gain, if any, realized by Seller shareholders who receive Purchaser Common Stock and cash (other than cash in lieu of a fractional share interest of Purchaser Common Stock) in exchange for their shares of Seller Common Stock, will be recognized by each such shareholder, but in an amount not in excess of the amount of cash received. If the exchange has the effect of the distribution of a dividend, then the amount of the - 38 -

39 gain recognized shall be treated as a dividend. No loss will be recognized by such Seller shareholders on the exchange; (v) each seller shareholder's aggregate tax basis in any shares of Purchaser Common Stock received in the transaction will be the same as the aggregate tax basis of the shares of Seller Common Stock such shareholder surrendered in the exchange therefor, decreased by the amount of any cash received by the shareholder and increased by the amount of any income or gain recognized by the shareholder in the exchange; and (vi) Each Seller shareholder's holding period in any shares of Purchaser Common Stock received in the transaction will, in each instance, include the period during which the shares of Seller Common Stock surrendered in exchange therefor were held, provided that such shares of Seller Common Stock were held as capital assets by the shareholder on the Effective Date. In rendering the opinions described in this subsection (g), Arnold & Porter and Milbank, Tweed, Hadley & McCloy LLP may rely on representations and facts as provided by Purchaser and Seller, including, without limitation, the representations set forth in Revenue Procedure 86-42, 1986-2 C.B. 722. 5.2.

41 committing such breach and (y) such breach would entitle the non-breaching party not to consummate the transactions contemplated hereby under Article 5 hereof; (c) At any time, by any party hereto in writing, if the applications for prior approval referred to in Section 4.3 hereof have been finally denied, and the time period for appeals and requests for reconsideration has run, or if any governmental entity of competent jurisdiction shall have issued a final nonappealable order enjoining or otherwise prohibiting the Merger; (d) At any time, by any party hereto in writing, if the shareholders of Seller do not approve the transactions contemplated herein upon a vote held at the special meeting duly called for that purpose or any adjournment thereof; (e) By any party hereto in writing, if the Closing Date has not occurred by the close of business on June 30, 2001 unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements set forth herein; (f) By Seller, upon the execution by Seller of a definitive agreement relating to a Takeover Proposal (as defined in Section 4.7(b)(13)), provided that (i) Seller shall have complied with its obligations under Section 4.7(b)(13) hereof, (ii) the Board of Directors of Seller shall have determined, after having received the advice of outside legal counsel to Seller and the advice of Seller's financial advisor, that such action is necessary for the Board of Directors to act in a manner consistent with its fiduciary duties under applicable law and (iii) concurrent with its notification of termination, Seller will wire to an account designated by Purchaser $24 million in immediately available funds, less Total Profit as defined in the Option Agreement, if any, theretofor actually realized by Purchaser, whereupon the option granted to Purchaser pursuant to the Option Agreement shall lapse (including with respect to shares as to which an exercise has been made under the Stock Option Agreement but which shares have not yet been issued); or (g) At any time, by Seller, if there is a "change of control" of Purchaser (as defined below).

WITNESSETH WHEREAS, the respective Boards of Directors of Seller, Merger Sub and Purchaser deem the merger of Seller with and into Merger Sub, under and pursuant to the terms and conditions herein set forth or referred to, desirable and in the best interests of the respective corporations and their respective shareholders, and the respective Boards of Directors of Seller, Merger Sub and Purchaser have adopted resolutions approving this Plan of Merger and an Agreement and Plan of Reorganization dated of even date herewith ("Reorganization Agreement"); and WHEREAS, the parties hereto desire that Seller shall be acquired by Purchaser through the merger of Seller with and into Merger Sub, with Merger Sub as the surviving corporation, subject to the terms and conditions of this Plan of Merger and the Reorganization Agreement; and WHEREAS, the parties hereto intend that the Merger shall qualify as a reorganization under Section 368(a) of the Internal Revenue Code of 1986, as amended ("the Code"). NOW, THEREFORE, in consideration of the premises and of the mutual agreements herein contained, the parties hereto do hereby agree as follows:

48 ARTICLE 1. MERGER Subject to the terms and conditions of this Plan of Merger, at the Effective Time (as hereinafter defined), Seller shall be merged with and into Merger Sub, pursuant to the provisions of, and with the effect provided in the New York Business Corporation Law and the Delaware General Corporation Law (said transaction being hereinafter referred to as the "Merger"). At the Effective Time, the separate existence of Seller shall cease and Merger Sub, as the surviving entity, shall continue unaffected and unimpaired by the Merger. (Merger Sub as existing at and after the Effective Time being hereinafter sometimes referred to as the "Surviving Corporation"). ARTICLE 2. CERTIFICATE OF INCORPORATION AND BY-LAWS Subject to Section 4.11(g) of the Reorganization Agreement, the Certificate of Incorporation and the Bylaws of Merger Sub in effect immediately prior to the Effective Time shall be the Certificate of Incorporation and the Bylaws of the Surviving Corporation, in each case until amended in accordance with applicable law. ARTICLE 3. BOARD OF DIRECTORS The directors and officers of Merger Sub immediately prior to the Effective Time shall be the directors and officers of the Surviving Corporation, each to hold office in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation. ARTICLE 4. CAPITAL At the Effective Time, all of the shares of capital stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall remain outstanding and unchanged by virtue of the Merger and shall constitute all of the issued and outstanding shares of capital stock of the Surviving Corporation. ARTICLE 5. CONVERSION AND EXCHANGE OF SELLER SHARES; FRACTIONAL SHARE INTERESTS 1. At the Effective Time, each share of the common stock of Seller, par value $0.80 per share ("Seller Common Stock"), issued and outstanding immediately prior to the Effective Time (except as provided in Section 2 of this Article 5, and subject to Sections 5 and 7 of this Article 5), shall, by virtue of the Merger, automatically and without any action on the part of the holder thereof, become and be converted into, at the election of the holder as provided in and subject to the limitations set forth in this Article 5, either (i) the right to receive $21 in cash without interest (the "Cash Consideration") or (ii) an amount of common stock of Purchaser, par value $5.00 per share ("Purchaser Common Stock") equal to the quotient (the "Exchange Ratio") of (A) $21 divided by (B) the Market Value (as defined below) of a share of Purchaser Common Stock (the "Stock Consideration"). For purposes of this Plan of Merger, the "Market Value" of the - 2 -

49 Purchaser Common Stock shall be the average of the average of the high and low prices of the Purchaser Stock on the New York Stock Exchange-Composite Transactions List (as reported by The Wall Street Journal or, if not reported therein, another comparable authoritative source) for the 10 trading days immediately preceding the date on which the Effective Time occurs. The Cash Consideration and the Stock Consideration are sometimes referred to herein collectively as the "Merger Consideration." 2. At the Effective Time, all shares of Seller Common Stock held in the treasury of Seller or owned beneficially by any Subsidiary of Seller other than in a fiduciary capacity ("Trust Account Shares") or in connection with a debt previously contracted ("DPC Shares") and all shares of Seller Common Stock owned by Purchaser or owned beneficially by any subsidiary of Purchaser other than Trust Account Shares and DPC Shares shall be canceled and no cash, stock or other property shall be delivered in exchange therefor. 3. (a) An election form (an "Election Form") and other appropriate and customary transmittal materials, which shall specify that delivery shall be effected, and risk of loss and title to the certificates theretofore representing Seller Common Stock ("Certificates") shall pass, only upon proper delivery of such Certificates to a bank or trust company designated by Purchaser and reasonably satisfactory to Seller (the "Exchange Agent") in such form as Seller and Purchaser shall mutually agree shall be mailed on the Mailing Date (as defined below) to each holder of record of shares of Seller Common Stock (other than holders of shares of Seller Common Stock to be cancelled as provided in Section 2 of this Article 5) as of a record date which shall be the same date as the record date for eligibility to vote on the Merger. The "Mailing Date" shall be the date on which proxy materials relating to the Merger are mailed to holders of shares of Seller Common Stock. (b) Each Election Form shall entitle the holder of shares of Seller Common Stock (or the beneficial owner through appropriate and customary documentation and instructions) to (i) elect to receive the Cash Consideration for all of such holder's shares (a "Cash Election"), (ii) elect to receive the Stock Consideration for all of such holder's shares (a "Stock Election"), (iii) elect to receive the Cash Consideration with respect to some of such holder's shares and the Stock Consideration with respect to such holder's remaining shares (a "Mixed Election"), or (iv) make no election or to indicate that such holder has no preference as to the receipt of the Cash Consideration or the Stock Consideration (a "Non-Election"). Holders of record of shares of Seller Common Stock who hold such shares as nominees, trustees or in other representative capacities (a "Representative") may submit multiple Election Forms; provided, that such Representative certifies that each such Election Form covers all the shares of Seller Common Stock held by that Representative for a particular beneficial owner. Shares of Seller Common Stock as to which a Cash Election has been made are referred to herein as "Cash Election Shares." Shares of Seller Common Stock as to which a Stock Election has been made are referred to herein as "Stock Election Shares." Shares of Seller Common Stock as to which no election or a Non-Election has been made are referred to as "Non-Election Shares." The aggregate number of shares of Seller Common Stock with respect to which a Stock Election has been made is referred to herein as the "Stock Election Number." (c) To be effective, a properly completed Election Form shall be submitted to the Exchange Agent on or before 5:00 p.m. New York City time on the 30th calendar day following - 3 -

50 the Mailing Date (or such other time and date as Seller and Purchaser may mutually agree) (the "Election Deadline"). An election shall have been properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline. An Election Form shall be deemed properly completed only if accompanied by one or more Certificates (or customary affidavits and, if required by Purchaser pursuant to Section 8 of this Article 5, indemnification regarding the loss or destruction of such Certificates or the guaranteed delivery of such Certificates) representing all shares of Seller Common Stock covered by such Election Form, together with duly executed transmittal materials included with the Election Form. Any Seller shareholder may at any time prior to the Election Deadline change his or her election by written notice received by the Exchange Agent prior to the Election Deadline accompanied by a properly completed and signed revised Election Form. Any Seller shareholder may, at any time prior to the Election Deadline, revoke his or her election by written notice received by the Exchange Agent prior to the Election Deadline or by withdrawal prior to the Election Deadline of his or her Certificates, or of the guarantee of delivery of such Certificates, previously deposited with the Exchange Agent. All elections shall be revoked automatically if the Exchange Agent is notified in writing by Purchaser and Seller that this Plan of Merger has been terminated. If a shareholder either (i) does not submit a properly completed Election Form by the Election Deadline, or (ii) revokes its Election Form and does not thereafter duly deliver a properly completed Election Form to the Exchange Agent prior to the Election Deadline, the shares of Seller Common Stock held by such shareholder shall be designated "Non-Election Shares." Purchaser shall cause the Certificates representing Seller Common Stock described in (ii) to be promptly returned without charge to the person submitting the Election Form upon written request to that effect from the person who submitted the Election Form. Subject to the terms of this Plan of Merger and of the Election Form, the Exchange Agent shall have reasonable discretion to determine whether any election, revocation or change has been properly or timely made and to disregard immaterial defects in any Election Form, and any good faith decisions of the Exchange Agent regarding such matters shall be binding and conclusive. (d) Notwithstanding any other provision contained in this Plan of Merger, 50% of the total number of shares of Seller Common Stock outstanding on the date hereof, less the aggregate number of shares of Seller Common Stock acquired by Purchaser pursuant to the Reorganization Agreement or Seller prior to the Effective Time (the "Stock Conversion Number") shall be converted into the Stock Consideration and the remaining outstanding shares of Seller Common Stock shall be converted into the Cash Consideration (in each case, excluding shares of Seller Common Stock to be cancelled as provided in Section 2 of this Article 5 (the shares remaining outstanding after such exclusion constituting, for purposes of this Plan of Merger the "Outstanding Seller Shares"); provided, however, that for federal income tax purposes, it is intended that the Merger should qualify as a reorganization under the provisions of Section 368(a) of the Code and, notwithstanding anything to the contrary contained herein, in order that the Merger will not fail to satisfy continuity of interest requirements under applicable federal income tax principles relating to reorganizations under Section 368(a) of the Code, as reasonably determined by Arnold & Porter and Milbank, Tweed, Hadley & McCloy LLP, Purchaser shall increase the number of outstanding Seller shares that will be converted into the Stock Consideration and reduce the number of outstanding Seller shares that will be converted into the right to receive the Cash Consideration. - 4 -

51 (e) Within five (5) business days after the later to occur of the Election Deadline or the Effective Time, Purchaser shall cause the Exchange Agent to effect the allocation among holders of Seller Common Stock of rights to receive the Cash Consideration and the Stock Consideration as follows: (i) If the Stock Election Number exceeds the Stock Conversion Number, then all Cash Election Shares and all Non-Election Shares shall be converted into the right to receive the Cash Consideration, and, subject to Section 7 of this Article 5, each holder of Stock Election Shares will be entitled to receive the Stock Consideration in respect of that number of Stock Election Shares equal to the product obtained by multiplying (x) the number of Stock Election Shares held by such holder by (y) a fraction, the numerator of which is the Stock Conversion Number and the denominator of which is the Stock Election Number, with the remaining number of such holder's Stock Election Shares being converted into the right to receive the Cash Consideration; (ii) If the Stock Election Number is less than the Stock Conversion Number (the amount by which the Stock Conversion Number exceeds the Stock Election Number being referred to herein as the "Shortfall Number"), then all Stock Election Shares shall be converted into the right to receive the Stock Consideration and the Non-Election Shares and Cash Election Shares shall be treated in the following manner: (A) if the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Cash Election Shares shall be converted into the right to receive the Cash Consideration and, subject to Section 7 of Article 5, each holder of Non-Election Shares shall receive the Stock Consideration in respect of that number of Non-Election Shares equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such holder by (y) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares, with the remaining number of such holder's Non-Election Shares being converted into the right to receive the Cash Consideration; or (B) if the Shortfall Number exceeds the number of Non-Election Shares, then all Non-Election Shares shall be converted into the right to receive the Stock Consideration, and, subject to Section 7 of this Article 5, each holder of Cash Election Shares shall receive the Stock Consideration in respect of that number of Cash Election Shares equal to the product obtained by multiplying (x) the number of Cash Election Shares held by such holder by (y) a fraction, the numerator of which is the amount by which (1) the Shortfall Number exceeds (2) the total number of Non-Election Shares and the denominator of which is the total number of Cash Election Shares, with the remaining number of such holder's Cash Election Shares being converted into the right to receive the Cash Consideration. - 5 -

52 For purposes of this Section 3(e), if Purchaser is obligated to increase the number of Outstanding Seller Shares to be converted into shares of Purchaser Common Stock as a result of the application of the last clause of Section 3(d) above, then the higher number shall be substituted for the Stock Conversion Number in the calculations set forth in this Section 3(e). (f) All of the shares of Seller Common Stock converted into and exchangeable for the Merger Consideration pursuant to this Article 5 shall no longer be outstanding and shall automatically be cancelled and cease to exist as of the Effective Time, subject, however, to the Purchaser's obligation to pay, in accordance with and subject to the limitations of Section 4.14 of the Reorganization Agreement, any dividends which may have been declared by Seller on such shares of Purchaser Common Stock in accordance with the terms of this Plan of Merger and which remained unpaid as of the Effective Time. Each Certificate previously representing any such shares of Seller Common Stock shall thereafter represent the right to receive the Merger Consideration pursuant to this Article 5, as allocated among the holders of Seller Common Stock in accordance with this Section 3. (g) At the Effective Time, Purchaser shall deposit, or shall cause to be deposited, with the Exchange Agent, for exchange in accordance with this Section 3, certificates representing the aggregate number of shares of Purchaser Common Stock into which the outstanding shares of Seller Common Stock shall be converted pursuant to this Article 5, and cash in the amount of the aggregate Cash Consideration and the aggregate amount of cash to be paid in lieu of fractional shares. As soon as practicable after the Effective Time, the Exchange Agent shall mail to all holders of record of Seller Common Stock who did not previously submit completed Election Forms letters of transmittal specifying the procedures for the delivery of such holders' certificates to the Exchange Agent and describing the Merger Consideration such holders will receive therefor. Also as soon as practicable after the Effective Time (with allowance for the mailing of the letters of transmittal described in the preceding sentence), the Exchange Agent shall distribute to holders of shares of Seller Common Stock, upon surrender to the Exchange Agent (to the extent not previously surrendered with an Election Form) of one or more Certificates for cancellation, (i) a certificate representing that number of whole shares of Purchaser Common Stock, if any, that such holder has the right to receive pursuant to this Plan of Merger, and (ii) a check for an amount equal to the cash, if any, which such holder has the right to receive pursuant to this Plan of Merger (including any cash in lieu of any fractional shares of Purchaser Common Stock to which such holder is entitled pursuant to Section 7 hereof and any dividends or other distributions to which such holder is entitled pursuant to the provisions set forth below). In no event shall the holder of any such surrendered Certificates be entitled to receive interest on any of the Cash Consideration or cash in lieu of fractional share interests to be received in the Merger. If a check is to be issued in the name of a person other than the person in whose name the Certificates surrendered for exchange therefor are registered, it shall be a condition of the exchange that the person requesting such exchange shall pay to the Exchange Agent any transfer taxes required by reason of issuance of such check to a person other than the registered holder of the Certificates surrendered, or shall establish to the reasonable satisfaction of the Exchange Agent that such tax has been paid or is not applicable. No dividends or other distributions declared after the Effective Time with respect to Purchaser Common Stock shall be paid to the holder of any unsurrendered Certificate until the holder thereof shall surrender such Certificate in accordance with this Article 5. After the surrender of a Certificate in accordance with this Article 5, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, - 6 -

53 which theretofore had become payable with respect to shares of Purchaser Common Stock, if any, represented by such Certificate. Certificates surrendered for exchange by any person who is an "affiliate" of Seller for purposes of Rule 145(c) under the Securities Act of 1933, as amended, shall not be exchanged for certificates representing shares of Purchaser Common Stock until Purchaser has received the written agreement of such person contemplated by Section 4.10 of the Reorganization Agreement. If any certificate for shares of Purchaser Common Stock is to be issued in a name other than that in which a Certificate surrendered for exchange is issued, the Certificate so surrendered shall be properly endorsed and otherwise in proper form for transfer and the person requesting such exchange shall affix any requisite stock transfer tax stamps to the Certificate surrendered or provide funds for their purchase or establish to the reasonable satisfaction of Purchaser or its agent that such taxes have been paid or are not payable. Any portion of the Merger Consideration which remains undistributed to the shareholders of Seller for six months after the Effective Time shall be delivered to Purchaser, upon demand, and any shareholders of Seller who have not theretofore complied with this Article 5 shall thereafter look only to Purchaser (subject to abandoned property, escheat and other similar laws) as general creditors for payment of their claim for Purchaser Common Stock or Cash Consideration and any cash in lieu of fractional shares of Purchaser Common Stock and any dividends or distributions with respect to Seller Common Stock. The Exchange Agent shall send notice to the shareholders of Seller who have not submitted their Certificates 90 days after the Effective Time, and again 120 days after such time. 4. At the Effective Time, the stock transfer books of Seller shall be closed and no transfer of Seller Common Stock shall thereafter be made or recognized. If, after the Effective Time, Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for the Merger Consideration as provided in this Article 5. Any other provision of this Plan of Merger notwithstanding, neither Purchaser or its agent nor any party to the Merger shall be liable to a holder of Seller Common Stock for any amount paid or properly delivered in good faith to a public official pursuant to any applicable abandoned property, escheat or similar law. 5. In the event that prior to the Effective Time, the outstanding shares of Purchaser Common Stock shall have been increased, decreased or changed into or exchanged for a different number or kind of shares or securities by reorganization, recapitalization, reclassification, stock dividend, stock split or other like changes in Purchaser's capitalization, then an appropriate and proportionate adjustment shall be made to the Stock Consideration (including the Exchange Ratio) and the formulas contained in Section 6 of this Article 5. 6. (a) At the Effective Time, each option to acquire Seller Common Stock or stock appreciation rights with respect to Seller Common Stock (each a "Seller Option") granted under the Community Bancorp, Inc. 1988 Non-Qualified Stock Option Plan, the Community Bancorp, Inc. Incentive Stock Option Plan, the Progressive Bank, Inc. 1997 Employee Stock Option Plan, the Progressive Bank, Inc. Non-Qualified Stock Option Plans for Directors, the Pawling Savings Bank Incentive Stock Option Plan, the Premier National Bancorp, Inc. 1995 Incentive Stock Plan and the Fishkill National Corporation Incentive Stock Option Plan (collectively, the "Seller Stock Option Plans") which is outstanding immediately prior to the Effective Time, whether vested or unvested, will be assumed by Purchaser. Each Seller Option so assumed by Purchaser shall continue to have, and be subject to, the same terms and conditions set - 7 -

54 forth in the Seller Stock Option Plan (and any agreement) under which it was granted and as in existence immediately prior to the Effective Time, except that (i) such Seller Option shall be exercisable (when vested) for that number of whole shares of Purchaser Common Stock equal to the product of the number of shares of Seller Common Stock covered by the Seller Option multiplied by the Exchange Ratio; provided that any fractional shares of Purchaser Common Stock resulting from such multiplication shall be rounded down to the nearest share; and (ii) the exercise price per share of Purchaser Common Stock shall be equal to the exercise price per share of Seller Common Stock of such Seller Option divided by the Exchange Ratio; provided that such exercise price shall be rounded up to the nearest cent. Notwithstanding the foregoing, the adjustment provided herein will comply with the adjustment provisions in the Seller Stock Option Plans and with respect to any Seller Options that are "incentive stock options" (as defined in Section 422 of the Code) shall be and is intended to be effected in a manner which is consistent with Section 424(a) of the Code. (b) As soon as practicable after the Effective Time, Purchaser shall deliver to the persons who hold stock options or stock appreciation rights granted under the Seller Stock Option Plans notices describing the effect of the Merger on stock options or stock appreciation rights granted under the Seller Stock Option Plans. (c) Purchaser shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Purchaser Common Stock for delivery under the Seller Stock Option Plans as adjusted in accordance with this Section. As soon as practicable after the Effective Time, Purchaser shall file a registration statement on Form S-8 promulgated by the SEC under the Securities Act (or any successor or other appropriate form) with respect to the Purchaser Common Stock subject to such options or stock appreciation rights and shall use its best efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as such options or stock appreciation rights remain outstanding. With respect to those individuals who subsequent to the Merger will be subject to the reporting requirements under Section 16(a) of the Exchange Act, where applicable, Purchaser shall administer the Seller Stock Option Plans in a manner that complies with Rule 16b-3 promulgated under the Exchange Act. 7. Notwithstanding any other provision hereof, each holder of shares of Seller Common Stock who would otherwise have been entitled to receive pursuant to this Article 5 a fraction of a share of Purchaser Common Stock (after taking into account all Certificates delivered by such holder) shall receive, in lieu thereof, cash in an amount equal to such fraction of a share of Purchaser Common Stock multiplied by the Market Value of Purchaser Common Stock. No such holder shall be entitled to dividends, voting rights or any other shareholder right in respect of such fractional share. 8. In the event any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Purchaser, the posting by such person of a bond in such amount as Purchaser may reasonably direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the shares of Purchaser Common Stock constituting the Stock Consideration and cash - 8 -

55 in lieu of fractional shares and/or the cash constituting the Cash Consideration deliverable in respect thereof pursuant to this Plan of Merger. ARTICLE 6. EFFECTIVE TIME OF THE MERGER A certificate or articles of merger evidencing the transactions contemplated herein shall be delivered to the New York Department of State and the Delaware Secretary of State for filing as provided in the Reorganization Agreement. The Merger shall be effective at the time and on the date specified in such certificate or articles of merger (such date and time being herein referred to as the "Effective Time"). ARTICLE 7. CONDITIONS PRECEDENT The obligations of Purchaser, Merger Sub and Seller to effect the Merger as herein provided shall be subject to satisfaction, unless duly waived, of the conditions to the obligations of such person set forth in Article 5 of the Reorganization Agreement. ARTICLE 8. TERMINATION Anything contained in the Plan of Merger to the contrary notwithstanding, and notwithstanding adoption hereof by the shareholders of Seller or Merger Sub, this Plan of Merger may be terminated and the Merger abandoned as provided in the Reorganization Agreement. ARTICLE 9. MISCELLANEOUS 1. This Plan of Merger may be amended or supplemented at any time prior to the Effective Time by mutual agreement of Merger Sub, Purchaser and Seller. Any such amendment or supplement must be in writing and approved by their respective Boards of Directors and/or by officers authorized thereby and shall be subject to the proviso in Section 6.4 of the Reorganization Agreement. 2. Any notice or other communication required or permitted under this Plan of Merger shall be given, and shall be effective, in accordance with the provisions of the Reorganization Agreement. 3. The headings of the several Articles herein are inserted for convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Plan of Merger. 4. This Plan of Merger shall be governed by and construed in accordance with the laws of New York and Delaware applicable to the internal affairs of Seller and Merger Sub. - 9 -

56 5. This Plan of Merger, taken together with the Reorganization Agreement, shall constitute a "plan of reorganization" within the meaning of Section 1.368-2(g) of the Treasury Regulations promulgated under the Code. [Remainder of this page left intentionally blank.] - 10 -

1 EXHIBIT 99.2 STOCK OPTION AGREEMENT THE TRANSFER OF THIS AGREEMENT IS SUBJECT TO CERTAIN PROVISIONS CONTAINED HEREIN AND TO RESALE RESTRICTIONS UNDER THE SECURITIES ACT OF 1933, AS AMENDED STOCK OPTION AGREEMENT, dated July 9, 2000, between Premier National Bancorp Inc., a New York corporation ("Issuer"), and M&T Bank Corporation, a New York corporation ("Grantee"). W I T N E S S E T H: WHEREAS, Grantee, Issuer and Olympia Financial Corp., a Delaware corporation and a wholly owned subsidiary of Grantee ("Merger Sub") have entered into an Agreement and Plan of Reorganization of even date herewith (the "Reorganization Agreement"), which agreement has been executed by the parties hereto immediately prior to this Stock Option Agreement (the "Agreement"), and will enter into an Agreement and Plan of Merger to be dated as of the date of this Agreement (the "Plan of Merger," and, together with the Reorganization Agreement, the "Merger Agreements"); and WHEREAS, as a condition to Grantee's entering into the Merger Agreements and in consideration therefor, Issuer has agreed to grant Grantee the Option (as hereinafter defined); NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements set forth herein and in the Merger Agreements, the parties hereto agree as follows: 1. (a) Issuer hereby grants to Grantee an unconditional, irrevocable option (the "Option") to purchase, subject to the terms hereof, up to 3,144,107 fully paid and nonassessable shares of Issuer's Common Stock, par value $0.80 per share ("Common Stock"), at a price of $13.375 per share (the "Option Price"); provided, however, that in no event shall the number of shares of Common Stock for which this Option is exercisable exceed 19.9% of the Issuer's issued and outstanding shares of Common Stock without giving effect to any shares subject to or issued pursuant to the Option. The number of shares of Common Stock that may be received upon the exercise of the Option and the Option Price are subject to adjustment as herein set forth. Notwithstanding anything else in this Agreement to the contrary, the number of shares of Common Stock subject to the Option shall be reduced to such lesser number, if any, as may from time to time be necessary, but only for so long as may be necessary, to cause Grantee not to become an "interested shareholder" for purposes of Section 912 of the New York Business Corporation Law.

2 (b) In the event that any additional shares of Common Stock are either (i) issued or otherwise become outstanding after the date of this Agreement (other than pursuant to this Agreement or as permitted under the terms of the Merger Agreements) or (ii) redeemed, repurchased, retired or otherwise cease to be outstanding after the date of the Agreement, the number of shares of Common Stock subject to the Option shall be increased or decreased, as appropriate, so that, after such issuance, such number equals 19.9% of the number of shares of Common Stock then issued and outstanding without giving effect to any shares subject or issued pursuant to the Option. Nothing contained in this Section 1(b) or elsewhere in this Agreement shall be deemed to authorize Issuer or Grantee to breach any provision of the Merger Agreements. 2. (a) The Holder (as hereinafter defined) may exercise the Option, in whole or part, and from time to time, if, but only if, both an Initial Triggering Event (as hereinafter defined) and a Subsequent Triggering Event (as hereinafter defined) shall have occurred prior to the occurrence of an Exercise Termination Event (as hereinafter defined), provided, however, that the Holder shall have sent the written notice of such exercise (as provided in subsection (e) of this Section 2) within six months following such Subsequent Triggering Event; provided, further, however, that if the Option cannot be exercised on any day because of any injunction, order or similar restraint issued by a court of competent jurisdiction, the period during which the Option may be exercised shall be extended so that the Option shall expire no earlier than on the 10th business day after such injunction, order or restraint shall have been dissolved or when such injunction, order or restraint shall have become permanent and no longer subject to appeal, as the case may be, but in any event within one year following the Subsequent Triggering Event. Each of the following shall be an "Exercise Termination Event": (i) the Effective Date (as defined in the Plan of Merger) of the Merger; (ii) termination of the Merger Agreements in accordance with the provisions thereof if such termination occurs prior to the occurrence of an Initial Triggering Event; or (iii) the passage of twelve months after termination of the Merger Agreements if such termination follows the occurrence of an Initial Triggering Event. The term "Holder" shall mean the holder or holders of the Option. Notwithstanding anything to the contrary contained herein, the Option may not be exercised (nor may Grantee's rights under Section 10 hereof be exercised) at any time when Grantee shall be in breach of any of its covenants or agreements contained in the Merger Agreements under circumstances that would entitle Issuer to terminate the Merger Agreements (without regard to any grace period provided for in Section 6.1(b)(x) of the Reorganization Agreement). In the event that Issuer terminates the Merger Agreement pursuant to Section 6.1(f) of the Reorganization Agreement, then immediately upon Grantee's receipt of the wire transfer contemplated by such Section 6.1(f), this Agreement shall terminate and shall become void and have no further force or effect and Grantee shall surrender this Agreement to Issuer. (b) The term "Initial Triggering Event" shall mean any of the following events or transactions occurring after the date hereof: (i) Issuer or any of its Subsidiaries (each an "Issuer Subsidiary"), without having received Grantee's prior written consent, shall have entered - 2 -

3 into an agreement to engage in an Acquisition Transaction (as hereinafter defined) with any person (the term "person" for purposes of this Agreement having the meaning assigned thereto in Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the rules and regulations thereunder) other than Grantee or any of its Subsidiaries (each a "Grantee Subsidiary"). For purposes of this Agreement, "Acquisition Transaction" shall mean (w) a merger or consolidation, or any similar transaction, involving Issuer or any Significant Subsidiary (as defined in Rule 1-02 of Regulation S-X promulgated by the Securities and Exchange Commission (the "SEC")) of Issuer, (x) a purchase, lease or other acquisition or assumption of all or a substantial portion of the assets or deposits of Issuer or any Significant Subsidiary of Issuer, (y) a purchase or other acquisition (including by way of merger, consolidation, share exchange or otherwise) of securities representing 10% or more of the voting power of Issuer, or (z) any substantially similar transaction; provided, however, that in no event shall any merger, consolidation, purchase or similar transaction involving only the Issuer and one or more of its Subsidiaries or involving only two or more of such Subsidiaries, be deemed to be an Acquisition Transaction; provided that any such transaction is not entered into in violation of the terms of the Merger Agreements; (ii) Issuer or any Issuer Subsidiaries, without having received Grantee's prior written consent, shall have authorized, recommended, proposed, or publicly announced its intention to authorize, recommend or propose to engage in an Acquisition Transaction with any person other than Grantee or a Grantee Subsidiary; (iii) Any person (other than Grantee or any Subsidiary of Grantee) shall have acquired beneficial ownership or the right to acquire beneficial ownership of 10% or more of the outstanding shares of Common Stock (the term "beneficial ownership" for purposes of this Agreement having the meaning assigned thereto in Section 13(d) of the Exchange Act, and the rules and regulations thereunder) or any person other than Grantee or any Subsidiary of Grantee shall have commenced (as such term is defined under the rules and regulations of the SEC), or shall have filed or publicly disseminated a registration statement or similar disclosure statement with respect to, a tender offer or exchange offer to purchase any shares of Issuer Common Stock such that, upon consummation of such offer, such person would beneficially own, directly or indirectly, 10% or more of the then outstanding shares of Issuer Common Stock (such an offer being referred to herein as a "Tender Offer" or an "Exchange Offer," respectively); (iv) (A) the holders of Issuer Common Stock shall not have approved the Merger Agreements and the transactions contemplated thereby, at the meeting of such stockholders at which such agreement is voted on, (B) such meeting shall not have been held or shall have been cancelled prior to termination of the Merger Agreements, or (C) the Board of Directors of Issuer shall have publicly withdrawn or modified, or publicly announced its intent to withdraw or modify, in any manner adverse to Grantee, its recommendation that the stockholders of Issuer approve the transactions contemplated by the Merger Agreements, in each case after it shall have been publicly announced that any person other than Grantee or any Subsidiary of Grantee shall have (x) made, or disclosed an intention to make, a proposal to engage in an Acquisition - 3 -

4 Transaction, (y) commenced a Tender Offer, or filed or publicly disseminated a registration statement or similar disclosure statement with respect to an Exchange Offer, or (z) filed an application (or given a notice), whether in draft or final form, under any federal or state banking laws seeking regulatory approval to engage in an Acquisition Transaction; or (v) After an overture is made by a third party to Issuer or its stockholders to engage in an Acquisition Transaction, Issuer shall have breached any covenant or obligation contained in the Reorganization Agreement and such breach (x) would entitle Grantee to terminate the Merger Agreements and (y) shall not have been cured prior to the later of 30 days after written notice of breach is delivered or the Notice Date (as defined below). (c) The term "Subsequent Triggering Event" shall mean either of the following events or transactions occurring after the date hereof: (i) The acquisition by any person of beneficial ownership of 25% or more of the then outstanding shares of Common Stock; or (ii) The occurrence of the Initial Triggering Event described in paragraph (i) of subsection (b) of this Section 2, except that the percentage referred to in clause (y) shall be 25%. (d) Issuer shall notify Grantee promptly in writing of the occurrence of any Initial Triggering Event or Subsequent Triggering Event of which it has knowledge (together, a "Triggering Event"), it being understood that the giving of such notice by Issuer shall not be a condition to the right of the Holder to exercise the Option. (e) In the event the Holder is entitled to and wishes to exercise the Option, it shall send to Issuer a written notice (the date of which being herein referred to as the "Notice Date") specifying (i) the total number of shares it will purchase pursuant to such exercise and (ii) a place and date not earlier than three business days nor later than 60 business days from the Notice Date for the closing of such purchase (the "Closing Date"); provided, that if prior notification to or approval of the Federal Reserve Board or any other regulatory agency is required in connection with such purchase, the Holder shall promptly file the required notice or application for approval and shall expeditiously process the same and the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which any required notification periods have expired or been terminated or such approvals have been obtained and any requisite waiting period or periods shall have passed. Any exercise of the Option shall be deemed to occur on the Notice Date relating thereto, except that the Common Stock issuable pursuant to the Option shall not be deemed outstanding until they are issued in accordance with the provisions herein. (f) At the closing referred to in subsection (e) of this Section 2, the Holder shall pay to Issuer the aggregate purchase price for the shares of Common Stock - 4 -

5 purchased pursuant to the exercise of the Option in immediately available funds by wire transfer to a bank account designated by Issuer; provided, that failure or refusal of Issuer to designate such a bank account shall not preclude the Holder from exercising the Option. (g) At such closing, simultaneously with the delivery of immediately available funds as provided in subsection (f) of this Section 2, Issuer shall deliver to the Holder a certificate or certificates representing the number of shares of Common Stock purchased by the Holder and, if the Option should be exercised in part only, a new Option evidencing the rights of the Holder thereof to purchase the balance of the shares purchasable hereunder, and the Holder shall deliver to Issuer a copy of this Agreement and a letter agreeing that the Holder will not offer to sell or otherwise dispose of such shares in violation of applicable law or the provisions of this Agreement. (h) Certificates for Common Stock delivered at a closing hereunder may be endorsed with a restrictive legend that shall read substantially as follows: "THE TRANSFER OF THE SHARES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO CERTAIN PROVISIONS OF AN AGREEMENT BETWEEN THE REGISTERED HOLDER HEREOF AND ISSUER AND TO RESALE RESTRICTIONS ARISING UNDER THE SECURITIES ACT OF 1933, AS AMENDED. A COPY OF SUCH AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF ISSUER AND WILL BE PROVIDED TO THE HOLDER HEREOF WITHOUT CHARGE UPON RECEIPT BY ISSUER OF A WRITTEN REQUEST THEREFOR." It is understood and agreed that: (i) the reference to the resale restrictions of the Securities Act of 1933, as amended (the "Securities Act"), in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the Holder shall have delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel, in form and substance reasonably satisfactory to Issuer, to the effect that such legend is not required for purposes of the Securities Act; (ii) the reference to the provisions to this Agreement in the above legend shall be removed by delivery of substitute certificate(s) without such reference if the shares have been sold or transferred in compliance with the provisions of this Agreement and under circumstances that do not require the retention of such reference; and (iii) the legend shall be removed in its entirety if the conditions in the preceding clauses (i) and (ii) are both satisfied. In addition, such certificates shall bear any other legend as may be required by law. (i) Upon the giving by the Holder to Issuer of the written notice of exercise of the Option provided for under subsection (e) of this Section 2 and the tender of the applicable purchase price in immediately available funds and obtaining all regulatory approvals and the expiration of all statutory waiting periods, the Holder shall be deemed to be the holder of record of the shares of Common Stock issuable upon such exercise, notwithstanding that the stock transfer books of Issuer shall then be closed or - 5 -

6 that certificates representing such shares of Common Stock shall not then be actually delivered to the Holder. Issuer shall pay all expenses, and any and all United States federal, state and local taxes and other charges that may be payable in connection with the preparation, issue and delivery of stock certificates under this Section 2 in the name of the Holder or its assignee, transferee or designee. 3. Issuer agrees: (i) that it shall at all times maintain, free from preemptive rights, sufficient authorized but unissued or treasury shares of Common Stock so that the Option may be exercised without additional authorization of Common Stock after giving effect to all other options, warrants, convertible securities and other rights to purchase Common Stock; (ii) that it will not, by charter amendment or through reorganization, consolidation, merger, dissolution or sale of assets, or by any other voluntary act, avoid or seek to avoid the observance or performance of any of the covenants, stipulations or conditions to be observed or performed hereunder by Issuer; (iii) promptly to take all commercially reasonable action as may from time to time be required (including (x) complying with all premerger notification, reporting and waiting period requirements specified in 15 U.S.C. Section 18a and regulations promulgated thereunder and (y) in the event, under federal or state banking law, prior approval of or notice to the Federal Reserve Board or any other federal or state regulatory authority is necessary before the Option may be exercised, cooperating fully with the Holder in preparing such applications or notices and providing such information to the Federal Reserve Board or such other federal or state regulatory authority as they may require) in order to permit the Holder to exercise the Option and Issuer duly and effectively to issue shares of Common Stock pursuant hereto; and (iv) promptly to take all action provided herein to protect the rights of the Holder against dilution. 4. This Agreement (and the Option granted hereby) are exchangeable, without expense, at the option of the Holder, upon presentation and surrender of this Agreement at the principal office of Issuer, for other Agreements providing for Options of different denominations entitling the holder thereof to purchase, on the same terms and subject to the same conditions as are set forth herein, in the aggregate the same number of shares of Common Stock purchasable hereunder. The terms "Agreement" and "Option" as used herein include any Stock Option Agreements and related Options for which this Agreement (and the Option granted hereby) may be exchanged. Upon receipt by Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Agreement, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like tenor and date. Any such new Agreement executed and delivered shall constitute an additional contractual obligation on the part of Issuer, whether or not the Agreement so lost, stolen, destroyed or mutilated shall at any time be enforceable by anyone. 5. In addition to the adjustment in the number of shares of Common Stock that are purchasable upon exercise of the Option pursuant to Section 1 of this Agreement, the number of shares of Common Stock purchasable upon the exercise of the Option and the Option Price shall be subject to adjustment from time to time as provided - 6 -

7 in this Section 5. In the event of any change in, or distributions in respect of, the Common Stock by reason of stock dividends, split-ups, mergers, recapitalizations, combinations, subdivisions, conversions, exchanges of shares, distributions on or in respect of the Common Stock that would be prohibited under the terms of the Merger Agreement, or the like, the type and number of shares of Common Stock purchasable upon exercise hereof and the Option Price shall be appropriately adjusted so that Grantee on exercise will receive what it would have received had it exercised and held Common Stock immediately before such event. 6. Upon the occurrence of a Subsequent Triggering Event that occurs prior to an Exercise Termination Event, Issuer shall, at the request of Grantee delivered within six months of such Subsequent Triggering Event (whether on its own behalf or on behalf of any subsequent holder of this Option (or part thereof) or any of the shares of Common Stock issued pursuant hereto), promptly prepare, file and keep current a registration statement under the Securities Act covering this Option and any shares issued and issuable pursuant to this Option and shall use its reasonable best efforts to cause such registration statement to become effective and remain current in order to permit the sale or other disposition of this Option and any shares of Common Stock issued upon total or partial exercise of this Option ("Option Shares") in accordance with any plan of disposition requested by Grantee. Issuer will use its reasonable best efforts to cause such registration statement first to become effective and then to remain effective for such period not in excess of 180 days from the day such registration statement first becomes effective or such shorter time as may be reasonably necessary to effect such sales or other dispositions. The foregoing notwithstanding, Issuer may postpone filing or updating such registration for a reasonable period of time after receipt of the original request (not exceeding 180 days) if, in the good faith opinion of Issuer's board of directors, effecting the registration statement would adversely affect a material financing, acquisition, disposition of assets or stock, merger or other comparable transaction or would require Issuer to make public disclosure of information the public disclosure of which would have a material adverse effect upon Issuer, provided that the Issuer shall not delay such action pursuant to this sentence more than once in any twelve-month period. Grantee shall have the right to demand two such registrations. The foregoing notwithstanding, if, at the time of any request by Grantee for registration of the Option or Option Shares as provided above, Issuer is in registration with respect to an underwritten public offering of shares of Common Stock, and if in the good faith judgment of the managing underwriter or managing underwriters, or, if none, the sole underwriter or underwriters, of such offering the inclusion of the Holder's Option or Option Shares would interfere with the successful marketing of the shares of Common Stock offered by Issuer, the number of Option Shares otherwise to be covered in the registration statement contemplated hereby may be reduced; and provided, however, that after any such required reduction the number of Option Shares to be included in such offering for the account of the Holder or Holders shall constitute at least 25% of the total number of shares to be sold by the Holder or Holders and Issuer in the aggregate; and provided, further, however, that if such reduction occurs, then the Issuer shall file a registration statement for the balance as promptly as practicable and no reduction shall thereafter occur. Each such Holder shall provide all information reasonably requested by Issuer for inclusion in any registration - 7 -

8 statement to be filed hereunder. If requested by any such Holder in connection with such registration, Issuer shall become a party to any underwriting agreement relating to the sale of such shares, but only to the extent of obligating itself in respect of representations, warranties, indemnities and other agreements customarily included in secondary offering underwriting agreements for the Issuer. Upon receiving any request under this Section 6 from Grantee, Issuer agrees to send a copy thereof to any other person known to Issuer to be entitled to registration rights under this Section 6, in each case by promptly mailing the same, postage prepaid, to the address of record of the persons entitled to receive such copies. Notwithstanding anything to the contrary contained herein, in no event shall Issuer be obligated to effect more than two registrations pursuant to this Section 6 by reason of the fact that there shall be more than one Holder as a result of any assignment or division of this Agreement. In addition, Grantee agrees to use all reasonable efforts to cause, and to cause any underwriters of any safe or other disposition to cause, any sale or other disposition pursuant to such registration statement to be effected on a widely distribution basis so that upon consummation thereof no purchaser or transferee shall own beneficially more than 2% of the then outstanding voting power of the Issuer. 7. The periods for exercise of certain rights under Sections 2, 6, 10 and 12 shall be extended: (i) to the extent necessary to obtain all regulatory approvals for the exercise of such rights, and for the expiration of all statutory waiting periods; and (ii) to the extent necessary to avoid liability under Section 16(b) of the Exchange Act by reason of such exercise. 8. Issuer hereby represents and warrants to Grantee as follows: (a) Issuer has full corporate power and authority to execute and deliver this Agreement and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly and validly authorized by the Board of Directors of Issuer and no other corporate proceedings on the part of Issuer are necessary to authorize this Agreement or to consummate the transactions so contemplated. This Agreement has been duly and validly executed and delivered by Issuer. (b) Issuer has taken all necessary corporate action to authorize and reserve and to permit it to issue, and at all times from the date hereof through the termination of this Agreement in accordance with its terms will have reserved for issuance upon the exercise of the Option, that number of shares of Common Stock equal to the maximum number of shares of Common Stock at any time and from time to time issuable hereunder, and all such shares, upon issuance pursuant hereto, will be duly authorized, validly issued, fully paid, nonassessable, and will be delivered free and clear of all claims, liens, encumbrance and security interests and not subject to any preemptive rights. 9. Grantee hereby represents and warrants to Issuer that: - 8 -

9 (a) Grantee has all requisite corporate power and authority to enter into this Agreement and, subject to any approvals or consents referred to herein, to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly authorized by all necessary corporate action on the part of Grantee. This Agreement has been duly executed and delivered by Grantee. (b) The Option is not being, and any shares of Common Stock or other securities acquired by Grantee upon exercise of the Option will not be, acquired with a view to the public distribution thereof and will not be transferred or otherwise disposed of except in a transaction registered or exempt from registration under the Securities Act. 10. Neither of the parties hereto may assign any of its rights or obligations under this Agreement or the Option created hereunder to any other person, without the express written consent of the other party, except that in the event a Subsequent Triggering Event shall have occurred prior to an Exercise Termination Event, Grantee, subject to the express provisions hereof, may assign in whole or in part its rights and obligations hereunder within six months following such Subsequent Triggering Event (or such later period as provided in Section 7); provided, however, that until the date fifteen days following the date on which the Federal Reserve Board approves an application by Grantee to acquire the shares of Common Stock subject to the Option (proof of which approval shall be furnished promptly to Issuer), Grantee may not assign its rights under the Option except in (i) a widely dispersed public distribution, (ii) a private placement in which no one party acquires the right to purchase in excess of 2% of the voting shares of Issuer, (iii) an assignment to a single party (e.g., a broker or investment banker) for the purpose of conducting a widely dispersed public distribution on Grantee's behalf, or (iv) any other manner approved by the Federal Reserve Board. 11. Each of Grantee and Issuer will use its reasonable best efforts to make all filings with, and to obtain consents of, all third parties and governmental authorities necessary to the consummation of the transactions contemplated by this Agreement, including without limitation making application to list the shares of Common Stock issuable hereunder on the Amex upon official notice of issuance and applying to the Federal Reserve Board, for approval to acquire the shares issuable hereunder, and Grantee's ability to exercise the Option is conditioned on obtaining all such consents and approvals, but Grantee shall not be obligated to apply to state banking authorities for approval to acquire the shares of Common Stock issuable hereunder until such time, if ever, as it deems appropriate to do so. 12. (a) Upon the occurrence of a Subsequent Triggering Event that occurs prior to an Exercise Termination Event, (i) at the request of any Holder, delivered within thirty days following such occurrence (or such later period as provided in Section 7), Issuer shall repurchase the Option from the Holder at a price (the "Option Repurchase Price") equal to the amount by which (A) the market/offer price (as defined below) exceeds (B) the Option Price, multiplied by the number of shares for which this Option may then be exercised, plus, to the extent not previously reimbursed, Grantee's - 9 -

10 reasonable documented out-of-pocket expenses incurred in connection with the transactions contemplated by, and the enforcement of Grantee's rights under, the Merger Agreements, including without limitation reasonable legal, accounting and investment banking fees (the "Grantee's Out-of-Pocket Expenses"), and (ii) at the request of any owner of Option Shares from time to time (the "Owner"), delivered within thirty days following such occurrence (or such later period as provided in Section 7), Issuer shall repurchase such number of the Option Shares from such Owner as the Owner shall designate at a price per share ("Option Share Repurchase Price") equal to the greater of (A) the market/offer price and (B) the average option price per share paid by the Owner for the Option Shares so designated, plus, to the extent not previously reimbursed, Grantee's Out-of-Pocket Expenses. The term "market/offer price" shall mean the highest of (w) the price per share of the Common Stock at which a tender offer or exchange offer therefor constituting the Subsequent Trigger Event has been consummated, (x) the price per share of the Common Stock to be paid by any Person, other than Grantee or a subsidiary of Grantee, pursuant to an agreement with Issuer, (y) the highest closing price for shares of Common Stock within the 60-day period immediately preceding the required repurchase of Options or Option Shares, as the case may be, or (z) in the event of a sale of all or substantially all of Issuer's assets, the sum of the price paid in such sale for such assets and the current market value of the remaining net assets of Issuer as determined by a nationally recognized investment banking firm selected by a majority in the interest of the Holders or the Owners, as the case may be, and reasonably acceptable to Issuer, divided by the number of shares of Common Stock of Issuer outstanding at the time of such sale. In determining the market/offer price, the value of consideration other than cash shall be determined by a nationally recognized investment banking firm selected by a majority in interest of the Holders or the Owners, as the case may be, and reasonably acceptable to Issuer. (b) Each Holder and Owner, as the case may be, may exercise its right to require Issuer to repurchase the Option and any Option Shares pursuant to this Section 12 by surrendering for such purpose to Issuer, at its principal office, a copy of this Agreement or certificates for Option Shares, as applicable, accompanied by a written notice or notices stating that such Holder or Owner elects to require Issuer to repurchase this Option and/or Option Shares in accordance with the provisions of this Section 12 and a representation as to the ownership and freedom from liens. As promptly as practicable, and in any event within ten business days after the surrender of the Option and/or certificates representing Option Shares and the receipt of such notice or notices relating thereto, Issuer shall deliver or cause to be delivered to each Holder the Option Repurchase Price and/or to each Owner the Option Share Repurchase Price therefor or the portion thereof that Issuer is not then prohibited under applicable law and regulation from so delivering; provided, however, that the Holder may not exercise its right to require Issuer to repurchase the Option or any Option Shares more than one time. (c) To the extent that Issuer is prohibited under applicable law or regulation, or as a consequence of administrative policy, or as a result of a written agreement or other binding obligation with a governmental or regulatory body or agency, from repurchasing the Option and/or the Option Shares in full, Issuer shall immediately so notify each Holder and/or each Owner and thereafter deliver or cause to be delivered, - 10 -

11 from time to time, to such Holder and/or Owner, as appropriate, the portion of the Option Repurchase Price and the Option Share Repurchase Price, respectively, that it is no longer prohibited from delivering, within ten business days after the date on which Issuer is no longer so prohibited; provided, however, that if Issuer at any time after delivery of a notice of repurchase pursuant to paragraph (b) of this Section 12 is prohibited under applicable law or regulation, or as a consequence of administrative policy, from delivering to any Holder and/or Owner, as appropriate, the Option Repurchase Price and the Option Share Repurchase Price, respectively, in part or in full (and Issuer hereby undertakes to use its best efforts to receive any required regulatory and legal approvals and to file any required notices as promptly as practicable in order to accomplish such repurchase), such Holder or Owner may revoke its notice of repurchase of the Option or the Option Shares either in whole or to the extent of the prohibition, whereupon Issuer shall promptly (i) deliver to such Holder and/or Owner, as appropriate, that portion of the Option Purchase Price or the Option Share Repurchase Price that Issuer is not prohibited from delivering; and (ii) deliver, as appropriate, either (A) to such Holder, a new Stock Option Agreement evidencing the right of such Holder to purchase that number of shares of Common Stock obtained by multiplying the number of shares of Common Stock for which the surrendered Stock Option Agreement was exercisable at the time of delivery of the notice of repurchase by a fraction, the numerator of which is the Option Repurchase Price less the portion thereof theretofore delivered to the Holder and the denominator of which is the Option Repurchase Price, or (B) to such Owner, a certificate for the Option Shares it is then so prohibited from repurchasing. (d) At any time after the occurrence of a Subsequent Triggering Event and prior to the later of (a) the expiration of 24 months immediately following the first purchase of shares of Common Stock pursuant to the Option and (b) the termination of the Option, if Grantee shall desire to sell, assign, transfer or otherwise dispose of all or any of the Option or the shares of Common Stock or other securities acquired by it pursuant to the Option, it shall give Issuer written notice of the proposed transaction, identifying the proposed transferee, accompanied by a copy of a binding offer to purchase such shares or other securities signed by such transferee and setting forth the terms of the proposed transaction. Upon receipt of such notice, Issuer shall for a period of 10 business days have the right of first refusal to purchase the Option or the Common Stock then held by the Grantee that is proposed to be sold at the purchase price set forth in such notice. The purchase of any such shares or other securities shall be settled within 10 business days of the date of the acceptance of the offer and the purchase price shall be paid to Grantee in immediately available funds; provided that, if prior notification to or approval of any governmental or regulatory authority is required in connection with such purchase, Issuer shall promptly file the required notice or application for approval and shall expeditiously process the same (and Grantee shall cooperate with Issuer in the filing of any such notice or application and the obtaining of any such approval) and the period of time that otherwise would run pursuant to this sentence shall run instead from the date on which, as the case may be, (a) any required notification period has expired or been terminated or (b) such approval has been obtained and, in either event, any requisite waiting period shall have passed. In the event of the failure or refusal of Issuer to purchase all the shares or other securities covered by such notice or if any such governmental or regulatory authority disapproves Issuer's proposed - 11 -

12 purchase of such shares or other securities, Grantee may, within 60 days from the date of such notice (subject to any necessary extension for regulatory notification, approval or waiting periods), sell all, but not less than all, of such shares or other securities to the proposed transferee at no less than the price specified and on terms no more favorable than those set forth in such notice. The requirements of this Section 12(d) shall not apply to (w) any disposition as a result of which the proposed transferee would own beneficially not more than 2% of the outstanding voting power of Issuer, (x) any disposition of Common Stock or other securities by a person to whom Grantee has assigned its rights under the Option with the consent of Issuer, (y) any sale by means of public offering registered under the Securities Act in which steps are taken to reasonably assure that no purchaser will acquire securities representing more than 2% of the outstanding voting power of Issuer or (z) any transfer to a wholly-owned subsidiary of Grantee which agrees in writing to be bound by the terms thereof. 13. (a) Notwithstanding any other provision of this Agreement, in no event shall the Grantee's Total Profit (as hereinafter defined) exceed $24 million and, if it otherwise would exceed such amount, the Grantee, at its sole election, shall either (i) reduce the number of shares of Common Stock subject to this Option, (ii) deliver to the Issuer for cancellation Option Shares previously purchased by Grantee valued at fair market value at the time of delivery, (iii) pay cash to the Issuer, or (iv) undertake any combination thereof, so that Grantee's actually realized Total Profit shall not exceed $24 million after taking into account the foregoing actions. (b) Notwithstanding any other provision of this Agreement, this Option may not be exercised for a number of shares as would, as of the date of exercise, result in a Notional Total Profit (as defined below) of more than $24 million; provided, that nothing in this sentence shall restrict any exercise of the Option permitted hereby on any subsequent date. (c) As used herein, the term "Total Profit" shall mean the aggregate amount (before taxes) of (i)(x) the net cash amounts received by Grantee pursuant to the sale of Option Shares (or any other securities into which such Option Shares are converted or exchanged) to any unaffiliated party, including the Issuer, less (y) the Grantee's purchase price of such Option Shares, plus (ii) any amounts received by Grantee on the transfer of the Option (or any portion thereof) to any unaffiliated party, including the Issuer. (d) As used herein, the term "Notional Total Profit" with respect to any number of shares as to which Grantee may propose to exercise this Option shall be the Total Profit determined as of the date of such proposed exercise assuming that this Option were exercised on such date for such number of shares and assuming that such shares, together with all other Option Shares, including Shares underlying the Option itself, held by Grantee and its affiliates as of such date, were sold for cash at the closing market price for the Common Stock as of the close of business on the preceding trading day (less customary brokerage commissions). - 12 -

13 14. The parties hereto acknowledge that damages would be an inadequate remedy for a breach of this Agreement by either party hereto and that the obligations of the parties hereto shall be enforceable by either party hereto through injunctive or other equitable relief. 15. If any term, provision, covenant or restriction contained in this Agreement is held by a court or a federal or state regulatory agency of competent jurisdiction to be invalid, void or unenforceable, the remainder of the terms, provisions and covenants and restrictions contained in this Agreement shall remain in full force and effect, and shall in no way be affected, impaired or invalidated. If for any reason such court or regulatory agency determines that the Holder is not permitted to acquire the full number of shares of Common Stock provided in Section 1(a) hereof (as adjusted pursuant to Sections 1(b) or 5 hereof), it is the express intention of Issuer to allow the Holder to acquire such lesser number of shares as may be permissible, without any amendment or modification hereof. 16. All notices, requests, claims, demands and other communications hereunder shall be deemed to have been duly given when delivered in person, by cable, telegram, telecopy or telex, or by registered or certified mail (postage prepaid, return receipt requested) at the respective addresses of the parties set forth in the Reorganization Agreement. 17. This Agreement shall be governed by and construed in accordance with the laws of the State of New York, regardless of the laws that might otherwise govern under applicable principles of conflicts of laws thereof. 18. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement. 19. Except as otherwise expressly provided herein, each of the parties hereto shall bear and pay all costs and expenses incurred by it or on its behalf in connection with the transactions contemplated hereunder, including fees and expenses of its own financial consultants, investment bankers, accountants and counsel. 20. Except as otherwise expressly provided herein or in the Merger Agreements, this Agreement contains the entire agreement between the parties with respect to the transactions contemplated hereunder and supersedes all prior arrangements or understandings with respect thereto, written or oral. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and permitted assigns. Nothing in this Agreement, expressed or implied, is intended to confer upon any party, other than the parties hereto, and their respective successors and permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided herein. - 13 -

14 21. Capitalized terms used in this Agreement and not defined herein shall have the meanings assigned thereto in the Merger Agreement. - 14 -

15 IN WITNESS WHEREOF, each of the parties has caused this Agreement to be executed on its behalf by its officers thereunto duly authorized, all as of the date first above written.

Wilmers, president and chief executive officer of M&T, said, "Our merger with Premier, the largest independent bank in the mid-Hudson valley, will give M&T the number one market share and will significantly strengthen our presence in and commitment to the region.

M&T has succeeded in Upstate New York because we have developed an in-depth understanding of the region's markets and its customers." Following the merger, Mr. Cunningham will be elected to the boards of directors of M&T and its principal commercial bank subsidiary, Manufacturers and Traders Trust Company ("M&T Bank") and become chairman of the Hudson Valley Advisory Board of M&T Bank.

The merger will be accounted for as a purchase transaction and is anticipated to be completed in the first quarter of 2001. "Since this is an in-market transaction, we ultimately expect to be able to achieve cost savings exceeding 40% of Premier's operating expenses.

Pinto, executive vice president and chief financial officer of M&T. Premier also granted M&T an option to acquire up to 19.9% of the shares of common stock of Premier (more)
