(b) The Company shall have furnished to the Representatives an opinion of Wachtell, Lipton, ▇▇▇▇▇ & ▇▇▇▇, counsel to the Company, dated the Closing Date and addressed to the Representatives, in form and substance set forth on Exhibit A hereto;

(c) The Company shall have furnished to the Representatives an opinion of ▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Esq., Senior Vice President and General Counsel of the Company,

dated the Closing Date and addressed to the Representatives, in form and substance set forth on Exhibit B hereto;

(d) The Representatives shall have received from ▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Indenture, the Registration Statement, the Disclosure Package, the Final Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters.

(e) The Company shall have furnished to the Representatives a certificate of the Company, signed by any of the Chairman of the Board, a Vice Chairman of the Board, the President or any Executive or Senior Vice President and the principal financial or accounting officer of the Company, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Registration Statement, the Disclosure Package, the Final Prospectus and any supplements or amendments thereto, as well as each electronic road show, if used, in connection with the offering of the Securities, and this Agreement and that, to the best of his or her knowledge, after reasonable investigation:

(i) The representations and warranties of the Company in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Company has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

(ii) No stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or, to the Company’s knowledge, threatened; and

(iii) Except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto), since the date of the most recent financial statements included or incorporated by reference in the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto), there has been no material adverse change in the financial condition, business or results of operations of the Company and its subsidiaries on a consolidated basis.

(f) On the date of this Agreement and on the Closing Date, PricewaterhouseCoopers LLP shall have furnished to the Representatives, at the request of the Company, letters, dated the respective dates of delivery thereof and addressed to the Underwriters, in form and substance reasonably satisfactory to the Representatives and PricewaterhouseCoopers LLP, containing statements and information of the type customarily included in accountants’ “comfort letters” to underwriters with respect to the

financial statements and certain financial information contained or incorporated by reference in the Registration Statement, the Disclosure Package and the Final Prospectus; provided that the “cut-off” date for each such letter shall no more than five calendar days prior to the date thereof.

(g) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Final Prospectus (exclusive of any amendment or supplement thereto), there shall not have been (i) any change specified in the letter or letters referred to in paragraph (f) of this Section 6 or (ii) any adverse change, or any development involving a prospective adverse change, in or affecting the business or properties of the Company and its subsidiaries on a consolidated basis, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, makes it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Registration Statement (exclusive of any amendment thereof), the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto).

(h) The Securities shall have been rated “ A2” by ▇▇▇▇▇’▇ Investors Service, “A-” by Standard & Poor’s, a division of The McGraw Hill Companies, Inc., and “A-” by Fitch Ratings, or otherwise rated by at least two “nationally recognized statistical rating organizations” (as defined for purposes of Rule 436(g) under the Act) in one of its four highest categories.

(i) No downgrading in the rating accorded the Securities or any other debt securities of the Company by any “nationally recognized statistical rating organization” shall have occurred, and there shall not have been any public announcement that any such organization has under surveillance or review their ratings of the Securities or any other debt securities of the Company (other than an announcement with positive implications of a possible upgrading, and no implications of a possible downgrading, of such rating), if, in any such case, the effect thereof in the reasonable judgment of the Representatives makes it impracticable or inadvisable to proceed with the purchase of the Securities.

(j) Prior to the Closing Date, the Company shall have furnished to the Representatives such further information, documents and certificates as the Representatives may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled in all material respects when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be in all material respects reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at any time by the Representatives. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 shall be delivered at the office of ▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP, counsel for the Underwriters, at ▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇ ▇▇▇▇▇, on the Closing Date.

7. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless each Underwriter against any and all losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, or in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Final Prospectus, or any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 5(b) hereto, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and will reimburse each Underwriter, as incurred, for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement as originally filed or in any amendment thereof, the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Final Prospectus, or any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 5(b) hereto in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through the Representatives expressly for inclusion in the Registration Statement as originally filed or in any amendment thereof, the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Final Prospectus, or any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 5(b) hereto.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company against any and all losses, claims, damages or liabilities to which the Company may become subject under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement as originally filed or in any amendment thereof, the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement

relating to the Securities, the Final Prospectus, or any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 5(b) hereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, but only with reference to written information relating to such Underwriter furnished to the Company by or on behalf of such Underwriter through the Representatives expressly for inclusion in the Registration Statement as originally filed or in any amendment thereof, the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Final Prospectus, or any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 5(b) hereto. The Company acknowledges that the statements set forth (i) in the last paragraph of the cover page regarding delivery of the Securities and, under the heading “Underwriting”, (ii) the list of Underwriters and their respective participation in the sale of the Securities, and (iii) the sentences related to concessions and reallowances in any Preliminary Prospectus and the Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in any Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus.

(c) Promptly after receipt by an indemnified party under subsection (a) or (b) of this Section 7 of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) shall not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice

of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. In no event shall the indemnifying party be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent (which consent shall not be unreasonably withheld), but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) If the indemnification provided for in this Section 7 is unavailable or insufficient to hold harmless an indemnified party for any reason, then the Company and the Underwriters severally shall contribute to the aggregate amount paid or payable by such indemnified party as a result of any losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Underwriters on the other from the offering of the Securities to which such loss, claim, damage or liability (or action in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is unavailable for any reason, then the Company and the Underwriters severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case, as set forth on the cover page of the Final Prospectus. The relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or the Underwriters on the other, the intent of the parties, and their

relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending the same. Notwithstanding the provisions of this subsection (d), (i) in no case shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters in this subsection (d) to contribute are several in proportion to their respective purchase obligations with respect to the Securities and not joint. For purposes of this Section 7(d), each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

(e) The obligations of the Company under this Section 7 shall be in addition to any liability which the Company may otherwise have and shall extend, upon the same terms and conditions, to each director, officer, employee, Affiliate and agent of each Underwriter and to each person who controls any Underwriter within the meaning of either the Act or the Exchange Act; and the obligations of the Underwriters under this Section 7 shall be in addition to any liability that any Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each director, officer, employee, Affiliate and agent of the Company and to each person who controls the Company within the meaning of either the Act or the Exchange Act.

(f) The indemnity and contribution agreements contained in this Section 7 and the representations and warranties of the Company and the Underwriters in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of an Underwriter or any person controlling such Underwriter, or by or on behalf of the Company, its directors or officers, any authorized representative of the Company or any person controlling the Company, and (iii) acceptance of and payment for any of the Securities.

8. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such delivery and payment (i) trading in the Company’s Common Stock shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by U.S. federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by any Preliminary Prospectus or the Final Prospectus (exclusive of any amendment or supplement thereto).

9. Default by an Underwriter. If any one or more Underwriter shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for the Securities (in the respective proportions which the principal amount of Securities set forth opposite their names on Schedule II hereto bears to the aggregate principal amount of Securities set forth opposite the names of all remaining Underwriters) which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase exceeds 10% of the aggregate principal amount of the Securities set forth on Schedule II hereto, the remaining non-defaulting Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such non-defaulting Underwriters do not purchase all of the Securities, then this Agreement shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 5 hereof and the indemnity and contribution agreements in Section 7 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected.

10. Representations, Warranties and Indemnities to Survive. The respective agreements, indemnities, representations, warranties, and other statements of the Company and of the several Underwriters set forth in or made by or on behalf of them, respectively, pursuant to this Agreement shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter, or any officer or director or controlling person of any Underwriter, or the Company, or any officer or director or controlling person of the Company, and shall survive delivery of and payment for the Securities. The provisions of Sections 7 and 11 hereof shall survive the termination or cancellation of this Agreement.

11. Effect of Termination; Reimbursement of Expenses. If this Agreement shall be terminated pursuant to Section 9 hereof, the Company shall not then be under any liability to any Underwriter with respect to the Securities, except as provided in Section 5 and Section 7 hereof; but if for any other reason the Securities are not delivered by or on behalf of the Company as provided herein, the Company will reimburse the Underwriters severally through the Representatives for all out-of-pocket expenses, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, resale and delivery of such Securities, but the Company shall then be under no further liability to any Underwriter with respect to such Securities except as provided in Sections 5 and Section 7 hereof.

12. Notices. In all dealings hereunder, the Representatives of the Underwriters shall act on behalf of each such Underwriter, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representatives.

All statements, requests, notices and agreements and other communications hereunder shall be in writing and effective only on receipt, and, if sent to the Representatives, shall be mailed, delivered or telefaxed to (i) Citigroup Global Markets Inc., Attention: General Counsel (fax no.: (▇▇▇) ▇▇▇-▇▇▇▇), ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇▇▇, and (ii) Credit Suisse Securities (USA) LLC, Attention: LCD-IBD, ▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇-▇▇▇▇; or, if sent to the Company, will be mailed, delivered or telefaxed to M&T Bank Corporation, Attention: ▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Esq., (Fax No.: (▇▇▇) ▇▇▇-▇▇▇▇), ▇▇▇ ▇&▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors, employees, agents and controlling persons referred to in Section 7 hereof, and no other person will have any right or obligation hereunder. No purchaser of any of the Securities from any Underwriter shall be deemed a successor by reason merely of such purchase.

14. No Fiduciary Duty. The Company hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Company and (c) the Company’s engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Underwriters, or any of them, with respect to the subject matter hereof.

16. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

17. Waiver of Jury Trial. The Company hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

18. Counterparts. This Agreement may be signed in one or more counterparts, each of which shall constitute an original and all of which together shall constitute one and the same agreement.

(a) Each of the Company and its Significant Subsidiaries (as defined in Rule 1-02(w) of Regulation S-X of the Commission (the “Significant Subsidiaries”)) is a corporation duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation. Each of the Company and its Significant Subsidiaries has full power and authority (corporate and other) to own its properties and conduct its business as presently conducted as described in the Disclosure Package and the Final Prospectus and is duly registered and qualified to conduct its business and is in good standing in each jurisdiction or place in which the Company or such Significant Subsidiary owns or leases property or where the nature of its properties or the conduct of its business otherwise requires such registration or qualification, except where the failure to be so registered or qualified would not have a material adverse effect on the consolidated financial condition or results of operations of the Company.

(b) The Company is duly registered as a bank holding company under the Bank Holding Company Act of 1956, as amended.

(c) Manufacturers and Traders Trust Company, a banking corporation organized under the laws of the State of New York (“M&T Bank”), is a direct subsidiary of the Company and is an insured depository institution under the provisions of the Federal Deposit Insurance Act, as amended (the “FDI Act”). The deposit accounts at M&T Bank are insured by the Federal Deposit Insurance Corporation (the “FDIC”) in accordance with and to the extent provided in the FDI Act and the rules and regulations of the FDIC, and no proceedings for the termination or revocation of such insurance are pending, or, to the knowledge of the Company, threatened.

(d) The Underwriting Agreement has been duly authorized, executed and delivered by the Company.

(e) There is no pending or, to my knowledge, threatened action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company or any of its subsidiaries or its or their property, of a character required to be disclosed in the Registration Statement which is not adequately disclosed in any Preliminary Prospectus and the Final Prospectus, and there is no contract or other document of a character required to be described in the Registration Statement or Final Prospectus, or to be filed as an exhibit thereto, which is not described or filed as required.

(f) All the outstanding shares of capital stock of each Significant Subsidiary have been duly and validly authorized and issued and are fully paid and nonassessable, and, except as otherwise set forth in the Disclosure Package and the Final Prospectus, all outstanding shares of capital stock of the Significant Subsidiaries (other than M&T Real Estate Trust, a Maryland real estate investment trust (“M&T Real Estate”) are owned by the Company either directly or through wholly owned subsidiaries free and clear of any

perfected security interest and, to the knowledge of such counsel, after due inquiry, any other security interest, claim, lien or encumbrance. The Company owns all of the outstanding voting shares of capital stock and 88% of the outstanding preferred stock of M&T Real Estate either directly or through wholly-owned subsidiaries, free and clear of any perfected security interest or any other security interests, liens or encumbrances, other than such security interests, liens, and encumbrances which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the consolidated financial condition or results of operations of the Company.

(g) The Securities conform to the description thereof contained in the Disclosure Package and the Final Prospectus.

(h) None of the execution and delivery of the Underwriting Agreement or the Indenture, the issue and sale of the Securities, or the consummation of any other of the transactions contemplated in the Underwriting Agreement nor the fulfillment of the terms thereof will conflict with, result in a breach or violation of, or imposition of any lien, charge or encumbrance upon any property or assets of the Company or its subsidiaries pursuant to, (i) the charter or by-laws of the Company or its subsidiaries, (ii) to my knowledge, after reasonable investigation, the terms of any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which the Company or its subsidiaries is a party or bound or to which its or their property is subject, or (iii) any statute, law, rule, regulation, judgment, order or decree applicable to the Company or its subsidiaries of any court, regulatory body, administrative agency, governmental body, arbitrator or other authority having jurisdiction over the Company or its subsidiaries or any of its or their properties, except, in the case of clause (ii) and (iii) above, where such violation, conflict, breach or imposition would not have a material adverse effect upon the consolidated financial condition or results of operations of the Company.

(i) No holders of securities of the Company have rights to the registration of such securities under the Registration Statement.

(j) I have no reason to believe that on the Effective Date the Registration Statement contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading or that the Final Prospectus as of its date and on the Closing Date included or includes any untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (in each case, other than the financial statements and other financial information contained therein, as to which I express no opinion).

(k) I have no reason to believe that the Disclosure Package, as amended or supplemented at the Execution Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading (other than the financial statements and other financial information contained therein, as to which I express no opinion).
