The Plan Administrator shall establish a bookkeeping account (an "Account") for each Participant. As of the first day of the month in which a Deferred Bonus would have been paid to the Participant absent a Deferred Bonus Election, the amount of such Deferred Bonus shall be credited to such Participant's Account. 4.2 Deemed Earnings. As of each Revaluation Date, a Participant's Account shall be adjusted for Deemed Earnings since the preceding Revaluation Date. Where a Deferred Bonus is credited to an Account other than on a Revaluation Date, Deemed Earnings on the amount of such Deferred Bonus for the period from the date of such credit until the next succeeding Revaluation Date shall be a pro rata portion of Deemed Earnings on an equivalent amount for the period between the Revaluation Dates immediately preceding and succeeding the date of such credit, calculated by reference to the number of days in each period, except that Deemed Earnings on a M&T Bank Corporation Stock Deemed Investment Account shall be based on the actual dates of dividend payments on M&T Bank Corporation Common Stock. 4.3 Deemed Investment Portfolio. In his Deferred Bonus Agreement, a Participant shall designate a Deemed Investment Portfolio, and shall allocate his Deferred Bonus among the investment options offered for inclusion in the Deemed Investment Portfolio in integral multiples of 5 percent. A Participant may change such allocation on a calendar quarterly basis by submitting a written form to the Plan Administrator prior to the first day of such calendar quarter; provided, however, that a Participant may not change a prior allocation to his M&T - 5 - Bank Corporation Stock Deemed Investment Account other than to add to such Account. 4.4 Separate Accounting. Within a Participant's Account, the Plan Administrator shall account separately for each of the Participant's Deferred Bonuses. 4.5 M&T Bank Corporation Stock Deemed Investment Account. A Participant's M&T Bank Corporation Stock Deemed Investment Account shall be credited with the number of hypothetical shares of M&T Bank Corporation Common Stock that equals the portion of the Deferred Bonus as to which the Participant elected a hypothetical investment in such shares, divided by the closing price of a share of M&T Bank Corporation Common Stock on the New York Stock Exchange (or such other principal securities exchange on which the shares of Common Stock are traded if such shares are no longer traded on the New York Stock Exchange) on the effective date of the deferral, which shall be the date on which the Deferred Bonus would have been paid had it not been deferred, plus Deemed Earnings thereon. In the event of any change in corporate capital capitalization, such as a stock split, or a corporate transaction, such as any merger, consolidation, separation, including a spin-off, or other distribution of stock or property of the Employer, any reorganization (whether or not such reorganization comes within the definition of such term in Internal Revenue Code Section 368) or any partial or complete liquidation of the Employer, such adjustment shall be made in the number and class of hypothetical shares of M&T Bank Corporation Common Stock held in a Participant's M&T Bank Corporation Stock Deemed Investment Account as may be determined to be appropriate and equitable by the Plan Administrator in its sole discretion. - 6 - ARTICLE V PAYMENT OF BENEFITS 5.1 General Rule. Except as provided in the following sentence or in Section 5.2 hereof, a Participant (or, in the event of the Participant's death, his Beneficiary) shall receive (or begin to receive) payment of the amount standing to the Participant's Account as of the Revaluation Date or Dates next following the time or times elected in the Participant's Deferred Bonus Agreement or Agreements and shall receive such payment or payments in the form or forms elected in such Agreement or Agreements. If, however, a Participant terminates his employment with the Employer for any reason other than Retirement, the Plan Administrator, in its discretion, may direct that, rather than payment pursuant to the preceding sentence, a single payment shall be made of the amount standing to the Participant's Account as of any earlier Revaluation Date. 5.2 Hardship Withdrawals. In the event of Financial Hardship, a Participant may request a distribution of all or a portion of the amount standing to his Account. The determination of whether a Participant has incurred a Financial Hardship shall be made by the Plan Administrator. The Participant shall determine against which Deferred Bonus or Bonuses (and Deemed Earnings thereon) a withdrawal pursuant to this Section 5.2 shall be charged. 5.3 Payment. The payment to a Participant with respect to a Deferred Bonus (and Deemed Earnings thereon) shall be made in cash by the Participant's last Employer in the year with respect to which the Bonus deferred was payable; provided, however, that (a) if such Employer is owned directly or indirectly by a bank, the payment shall be made by such bank and - 7 - (b) payment from a Participant's M&T Bank Corporation Stock Deemed Investment Account shall be made in M&T Bank Corporation Common Stock (except to the extent that payment in M&T Bank Corporation Common Stock would result in a fractional share, in which case the amount that would constitute a fractional share shall be paid in cash, based on the closing price of a share of M&T Bank Corporation Common Stock on the New York Stock Exchange, or such other principal securities exchange on which the shares of Common Stock are traded if such shares are no longer traded on the New York Stock Exchange, on the Revaluation Date immediately preceding the date of payment). Payments of a Participant Account which (x) is not being paid in a single payment and (y) contains a M&T Bank Corporation Stock Deemed Investment Account as well as other amounts in the Account, shall be made in both cash and M&T Bank Corporation Common Stock pro rata in accordance with the values of the Participant's M&T Bank Corporation Stock Deemed Investment Account and the balance of the Participant's Account. 5.4 Tax Withholding. The Plan Administrator may make such provisions and take such steps as it may deem necessary or appropriate for the withholding by the Employers of all Federal, state, local or other taxes required by law to be withheld with respect to deferrals and payments under this Plan, including, without limitation, in the discretion of the Plan Administrator, (a) requiring the Participant (or Beneficiary, as the case may be) to pay, or provide for payment of, the amount of any such taxes, (b) deducting any such taxes from any amount otherwise payable to the Participant or Beneficiary in cash, including amounts payable under this Plan, or (c) reducing the number of shares of M&T Bank Corporation Common Stock - 8 - otherwise payable under this Plan by an amount (based on the closing price of such shares on the Revaluation Date immediately preceding the date the shares would otherwise have been paid) equal to the amount of any such taxes. ARTICLE VI BENEFICIARIES Each Participant may designate from time to time any person or persons, natural or otherwise, as his Beneficiary or Beneficiaries to whom benefits under Section 5.1 are to be paid in the event of his death. Each Beneficiary designation shall be made either in the Deferred Bonus Agreement or on a form provided by the Plan Administrator and shall be effective only when filed with the Plan Administrator during the Participant's lifetime. Each Beneficiary designation filed with the Plan Administrator shall revoke all Beneficiary designations previously made by the Participant. The revocation of a Beneficiary designation shall not require the consent of any designated Beneficiary. Payment to a Beneficiary shall be made in the form or forms elected in the Participant's Deferred Bonus Agreement or Agreements, provided that such payment shall be made in a single payment if a request for such a single payment is made by the Beneficiary and approved by the Plan Administrator. ARTICLE VII ADMINISTRATION 7.1 General. The Plan Administrator shall be charged with the administration of this Plan. The Plan Administrator shall have all such powers as may be necessary to discharge its - 9 - duties relative to the administration of this Plan, including by way of illustration and not limitation, discretionary authority to interpret and construe this Plan, to decide any dispute arising hereunder, to determine the right of any individual with respect to participation herein, to determine the right of any Participant with respect to benefits payable under this Plan and to adopt, alter and repeal such administrative rules, regulations and practices governing the operation of this Plan as it, in its sole discretion, may from time to time deem advisable. The Plan Administrator shall not be liable to any person for any action taken or omitted in connection with the interpretation and administration of this Plan unless attributable to willful misconduct or lack of good faith. The Plan Administrator shall be entitled to rely conclusively upon all tables, valuations, certificates, opinions and reports furnished by any actuary, accountant, controller, counsel or other person employed or engaged by the Plan Administrator or an Employer with respect to this Plan. The Plan Administrator, if an individual, or the members thereof if the Plan Administrator is a Committee, shall not participate in any action or determination regarding solely his or their own benefits payable hereunder. Except as provided in Section 7.3 hereof, decisions of the Plan Administrator made in good faith shall be final, conclusive and binding upon all parties. 7.2 Claims Procedure. Whenever the Plan Administrator denies, in whole or in part, a claim for benefits filed by any person (hereinafter referred to as a "Claimant"), the Plan Administrator shall transmit a written notice setting forth, in a manner calculated to be understood by the Claimant, a statement of the specific reasons for the denial of the claim, references to the specific provisions of this Plan on which the denial is based, a description of - 10 - any additional needed material or information and why such material or information is necessary, and an explanation of the claims review procedure as set forth herein. In addition, the written notice shall contain the date on which the notice was sent and a statement advising the Claimant that, within 90 days of the date on which such notice is received, he may obtain review of the Plan Administrator's decision. 7.3 Review Procedure.

Such written decision shall set forth, in a manner calculated to be understood by the Claimant, a statement of the specific reasons for the decision, including references to the specific provisions of this Plan which were relied upon. The decision will be final and binding on all persons concerned. ARTICLE VIII AMENDMENT AND TERMINATION 8.1 Power to Amend or Terminate. M&T Bank Corporation expects to continue this Plan indefinitely, but reserves the right to amend or terminate this Plan at any time, if, in its sole judgment, such amendment or termination is necessary or desirable. Any such amendment or termination shall be made in writing by the Board or its designee, if applicable, and shall be effective as of the date specified in such document. No amendment or termination of this Plan shall directly or indirectly deprive any Participant or Beneficiary of all or any portion of the amounts previously credited to the Participant's Account. In the event of a termination of this Plan, M&T Bank Corporation (or any transferee, purchaser or successor entity) may elect, in its discretion, either to have the Employers make a single payment, at the time of such termination, of the Account balances on such date to Participants and Beneficiaries or to have the Employers make payments to such individuals at such time or times as provided under the terms of this - 12 - Plan. 8.2 Successor. This Plan shall not be automatically terminated by a transfer or sale of an Employer or by the merger or consolidation of an Employer into or with any other corporation or other entity, but it shall be continued with respect to such Employer or its successor after such sale, merger or consolidation only if and to the extent that the transferee, purchaser or successor entity agrees to continue this Plan. In the event this Plan is not continued with respect to such Employer or its successor by the transferee, purchaser or successor entity, then it shall terminate with respect to such Employer or its successor subject to the provisions of Section 8.1 hereof. ARTICLE IX MISCELLANEOUS 9.1 No Effect on Employment Rights. Nothing contained herein will confer upon any Participant the right to be retained in the service of an Employer nor limit the right of an Employer to discharge or otherwise deal with Participants without regard to the existence of this Plan. 9.2 Plan Unfunded. Notwithstanding any provision herein to the contrary, the benefits offered hereunder shall constitute nothing more than unfunded, unsecured promises by each Employer to pay the amounts that such Employer is obligated to pay under this Plan. No provision shall at any time be made with respect to segregating any assets of any Employer for payment of any amounts hereunder. No Participant, Beneficiary or any other person shall have any interest in any particular assets of the Employers by reason of the right to receive a benefit under this Plan, and any such Participant, Beneficiary or other person shall have only the rights - 13 - of a general unsecured creditor of the Employer obligated to make payments to the Participant under this Plan. Nothing contained in this Plan shall constitute a guaranty by the Employers or any other entity or person that the assets of any Employer will be sufficient to pay any amount hereunder. All expenses and fees incurred in the administration of this Plan shall be paid by the Employers. 9.3 Binding on Employers, Employees and Their Successors. This Plan shall be binding upon and inure to the benefit of the Employers, their successors and assigns and each Participant and his heirs, executors, administrators and legal representatives. In the event of the merger or consolidation of an Employer with or into any other corporation, or in the event substantially all of the assets of an Employer shall be transferred to another corporation, the successor corporation resulting from the merger or consolidation, or the transferee of such assets, as the case may be, shall, as a condition to the consummation of the merger, consolidation or sale, assume the obligations of such Employer hereunder as of the date of such merger, consolidation or transfer and shall be substituted for such Employer hereunder. 9.4 Spendthrift Provisions. No amount payable under this Plan shall be subject in any manner to anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge prior to actual receipt thereof by the payee; and any attempt so to anticipate, alienate, sell, transfer, assign, pledge, encumber or charge prior to such receipt shall be void; and the Employers shall not be liable in any manner for or subject to the debts, contracts, liabilities, torts or engagements of any person entitled to any benefit under this Plan. 9.5 Disclosure. Each Participant shall receive a copy of this Plan, and the Plan - 14 - Administrator will make available for inspection by any Participant a copy of the rules and regulations used by the Plan Administrator in administering this Plan. 9.6 State Law. This Plan is established under and will be construed according to the laws of the State of New York to the extent that such laws are not preempted by ERISA. 9.7 Incapacity of Recipient. In the event a Participant or Beneficiary is declared incompetent and a guardian, conservator or other person legally charged with the care of his person or of his estate is appointed, any amounts to which such Participant or Beneficiary is entitled under this Plan shall be paid to such guardian, conservator or other person legally charged with the care of his person or his estate. Except as provided herein, when the Plan Administrator, in its sole discretion, determines that a Participant or Beneficiary is unable to manage his financial affairs, the Plan Administrator may direct the Employer, or Employers responsible for payment to make payments to any person for the benefit of such Participant or Beneficiary. 9.8 Unclaimed Benefit. Each Participant shall keep the Plan Administrator informed of his current address. The Plan Administrator shall not be obligated to search for the whereabouts of any person. If the location of a Participant is not made known to the Plan Administrator within three years after the date on which any payment of the Participant's benefit hereunder may be made, payment may be made as though the Participant had died at the end of the three-year period. If, within one additional year after such three-year period has elapsed, or, within three years after the actual death of a Participant, whichever occurs first, the Plan Administrator is unable to locate the Beneficiary of the Participant, the Participant and his - 15 - Beneficiary shall forfeit all rights to any payments under this Plan. 9.9 Elections, Applications, Notices. Every direction, revocation or notice authorized or required hereunder shall be deemed delivered to the Employers or the Plan Administrator as the case may be: (a) on the date it is personally delivered to the Plan Administrator (with a copy to the Bank's General Counsel) at the Bank's executive offices at Buffalo, New York or (b) three business days after it is sent by registered or certified mail, postage prepaid, addressed to the Plan Administrator (with a copy to the Bank's General Counsel) at the offices indicated above, and shall be deemed delivered to a Participant or Beneficiary: (a) on the date it is personally delivered to such individual, or (b) three business days after it is sent by registered or certified mail, postage prepaid, addressed to such individual at the last address shown for him on the records of the Employers.
