Exhibit 10.1

Execution Version

NON-COMPETITION AND NON-SOLICITATION AGREEMENT

THIS NON-COMPETITION AND NON-SOLICITATION AGREEMENT (the “Agreement”), dated as of February 21, 2021, by and among People’s United Financial, Inc. (the “Company”), a Delaware corporation, and John P. Barnes (“Executive”) is effective as of the Closing (as defined below) (the “Effective Date”). For purposes of this Agreement, Executive and the Company shall each be a “Party” and shall collectively be the “Parties”.

WITNESSETH

WHEREAS, Executive is (i) not currently subject to a post-employment non-competition covenant with respect to the Company and (ii) is currently subject to a post-employment non-solicitation covenant with respect to certain customers and employees of the Company;

WHEREAS, in connection with the transactions contemplated by the Agreement and Plan of Merger, dated as of February 21, 2021, between M&T Bank Corporation (“Parent”), Bridge Merger Corp., and the Company (as the same may be amended, restated, supplemented or otherwise modified from time to time, the “Merger Agreement”), and effective as of the closing of the transactions contemplated by the Merger Agreement (the “Closing”), Executive will cease to be employed by the Company and/or the Company Subsidiaries (as defined in the Merger Agreement);

WHEREAS, Executive and the Company are entering into this Agreement contemporaneously with the Merger Agreement, to be effective from and after the Closing; and

WHEREAS, in connection with the foregoing and subject to the occurrence of the Closing, the Company has determined that it is in the best interests of the Company and its stockholders, who will become stockholders of Blue as successor to the Company from and after the Closing, to enter into this Agreement embodying the terms of such non-competition covenant and non-solicitation covenant, subject to the terms and provisions of this Agreement.

NOW, THEREFORE, in consideration of the promises and mutual covenants contained herein and for other good and valuable consideration, the receipt and sufficiency of which are mutually acknowledged, the Parties hereby agree as follows:

Section 1. Covenant Not To Compete and Covenant Not to Solicit.

(a) Covenant Not to Compete. In consideration of the compensation to be paid to Executive under this Agreement and in addition to the restrictive covenants set forth in any other agreement between the Company or any Company Subsidiary, on the one hand, and Executive, on the other hand, Executive covenants that during the period of time commencing on the Effective Date and ending on the third anniversary of the Effective Date (such period, the “Restriction Period”), Executive shall not, without the prior written

consent of the Company, directly or indirectly, either for Executive or for or through any other individual, firm, partnership, corporation, or other entity own, manage, control, participate in, consult with, or render services for any business or enterprise that competes with any business or division of the Company or any Company Subsidiary (each, a “Related Entity”), in any geographic location within the United States in which the Company or a Related Entity operates. For purposes of this Agreement, the term “participate” includes any direct or indirect interest in any enterprise, whether as an officer, director, employee, partner, sole proprietor, agent, representative, independent contractor, consultant, franchisor, franchisee, advisor, creditor, owner or otherwise; provided that the term “participate” shall not include ownership of less than five percent of the common stock of a publicly held corporation whose common stock is traded on a national securities exchange or in the over-the-counter market. As of the Closing, Parent and the Parent Subsidiaries (as defined in the Merger Agreement) will each be a Related Entity for purposes of this Agreement.

(b) Covenant Not to Solicit. Notwithstanding any other agreement between the Company or any Company Subsidiary, on the one hand, and Executive, on the other hand, to the contrary, in consideration of the compensation to be paid to Executive under this Agreement, Executive agrees that the non-solicitation restrictions pursuant to the Company’s 2014 Amended and Restated Long-Term Incentive Plan, as amended from time to time, including any award agreements granted thereunder (the “2014 LTIP”), shall be extended to apply for the duration of the Restricted Period. As of the Closing, references to the “Company” for purposes of the non-solicitation restrictions under the 2014 LTIP will be deemed to include Parent and the Parent Subsidiaries.

Section 2. Compensation.

(a) Payment. In addition to any other payments or benefits that Executive may be entitled to as a result of a termination of his employment and in consideration for the covenants set forth in Section 1 hereof, upon and subject to the occurrence of the Closing, the Company agrees to pay Executive an amount equal to $18,000,000 (the “Restrictive Covenant Payment”), subject to the terms and conditions set forth herein. The Restrictive Covenant Payment will be paid in a lump sum within 30 days following the Effective Date. For the avoidance of doubt, Section 2(f) (“Certain Tax Provisions”) of the Change in Control Agreement (as defined below) will apply with respect to the Restrictive Covenant Payment.

(b) Clawback. In the event of a breach by Executive of any of the covenants and agreements contained in Section 1 prior to the end of the Restriction Period, the Company may, in its sole discretion, require that Executive pay to the Company, within 30 days following the date the Company first becomes aware of such breach, an amount equal to the after-tax portion of the Restrictive Covenant Payment received by Executive.

Section 3. Enforcement. In the event of a breach by Executive of any of the covenants and agreements contained in Section 1, to which the Company has not consented in writing, the Company shall be entitled to one or more of the following remedies, in addition to any other remedy provided for in this Agreement or as a matter of law, to the extent that such remedies are not by their nature exclusive:

2

(a) To seek repayment pursuant to Section 2(b) hereof;

(b) To collect through an action at law any damages sustained by the Company in excess of any amounts repaid pursuant to Section 2(b); and

(c) To obtain as appropriate, and without the necessity of showing actual damages: (i) an injunction against the continuation of any such breach by Executive, or (ii) specific performance of any negative covenant of Executive, it being agreed, in each case of clauses (i) and (ii), by Executive and the Company that money damages alone for such defaults by Executive would be inadequate.

Section 4. Reasonableness of Restrictions. Executive acknowledges and recognizes the highly competitive nature of the Company’s business, that access to confidential information renders Executive special and unique within the Company’s industry, and that Executive has had the opportunity to develop substantial relationships with existing and prospective clients, accounts, customers, consultants, contractors, investors, and strategic partners of the Company during the course of and as a result of Executive’s employment with the Company. In light of and in consideration for the foregoing, and in consideration of the compensation provided under this Agreement, Executive acknowledges and agrees that the restrictions and limitations set forth in this Agreement are reasonable and valid in geographical and temporal scope and in all other respects and are essential to protect the value of the business and assets of the Company. Executive further acknowledges that the restrictions and limitations set forth in this Agreement will not materially interfere with Executive’s ability to earn a living following the Effective Date.

Section 5. Taxes. The Company may withhold from any payments made under this Agreement all applicable taxes, including but not limited to income, employment, and social insurance taxes, as shall be required by law. Executive acknowledges and represents that the Company has not provided any tax advice to him in connection with this Agreement and that he has been advised by the Company to seek tax advice from his own tax advisors regarding this Agreement and payments that may be made to him pursuant to this Agreement, including specifically, the application of the provisions of Section 409A of the Code to such payments.

Section 6. Notice. Any notice to be given hereunder shall be deemed given when either mailed in the United States mails, postage prepaid, by registered or certified mail with return receipt requested or e-mailed to the applicable Party, in each case, to the addresses of the Parties specified by themselves.

Section 7. Waiver. No action, waiver or forbearance by the Company on any one occasion in pursuing any right or remedy to which it may be entitled under this Agreement shall operate to waive, modify or in any way affect or restrict the rights of the Company on any subsequent occasion, nor shall any action, waiver or forbearance by the Company under or with respect to any similar or dissimilar agreement with any past, present or future employee of the Company in any way modify, affect or restrict the rights of the Company under this Agreement.

Section 8. Entire Agreement; Blue Pencil. This is the entire agreement between the Parties relating to the subject matter of this Agreement and all prior discussions relating to it are merged herein other than the 2014 LTIP. This Agreement supersedes all prior agreements and oral understandings between the Parties; provided, that (i) this Agreement shall not affect any entitlements to severance payments or benefits that Executive may be entitled to pursuant to any other plan, policy, agreement or arrangement with, or maintained by, the Company or any Company Subsidiary, including, without limitation, the Change in Control Agreement, dated as of November 1, 2011, by and between the Company and Executive (the “Change in Control Agreement”) and (ii) the covenants set forth in Section 1 hereof shall be in addition to, and not in lieu of, any other restrictive covenants to which Executive is currently bound. No covenant or agreement contained herein shall be altered, modified or waived, except, in each instance, by an instrument in writing properly executed by the Party to be charged by such alteration, modification or waiver. If any term, clause or provision of this Agreement shall be judged by a court of competent jurisdiction to be invalid, the validity of any other term, clause or provision of this Agreement shall not be affected thereby. If any term, clause or provision in Section 1 shall be judged by a court of competent jurisdiction to exceed the scope of non- competition agreements permissible under applicable law, then such term, clause or provision shall be reformed to coincide with the maximum limitations permitted.

Section 9. Governing Law; Waiver of Jury Trial. This Agreement shall be governed by and construed in accordance with the laws of the State of Connecticut (excluding any that mandate the use of another jurisdiction’s laws). Each Party to this Agreement also hereby waives any right to trial by jury in connection with any suit, action, or proceeding under or in connection with this Agreement.

Section 10. Counterparts. This Agreement may be executed in two counterparts, each of which shall be deemed an original, but both of which together shall constitute one and the same instrument.

Section 11. Assignment. This Agreement shall be binding upon and shall inure to the benefit of the Parties hereto and their respective heirs, successors and permitted assigns. It is expressly understood and agreed that the benefits of this Agreement shall inure to any third party which shall succeed to the business of the Company, whether by way of consolidation, merger or otherwise, or to which all or substantially all of the assets of the Company (including its rights under this Agreement) shall be transferred or assigned, including, without limitation, pursuant to the Merger Agreement. It is also expressly understood and agreed that this Agreement is personal to Executive and cannot be assigned by Executive to any third party without the prior written consent of the Company; provided, however, that if Executive shall die, all amounts then payable to Executive hereunder shall be paid in accordance with the terms of this Agreement to Executive’s estate. Nothing expressed or referred to in this Agreement will be construed to give any person other than the Company, its Affiliates and Executive any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement.

Section 12. Section 409A Provisions.

Notwithstanding any provision in this Agreement to the contrary:

(a) Any payment otherwise required to be made hereunder to Executive at any date shall be delayed for such period of time as may be necessary to meet the requirements of Section 409A(a)(2)(B)(i) of the Code (the “Delay Period”). On the first business day following the expiration of the Delay Period, Executive shall be paid, in a single cash lump sum, an amount equal to the aggregate amount of all payments delayed pursuant to the preceding sentence, and any remaining payments not so delayed shall continue to be paid pursuant to the payment schedule set forth herein.

(b) Each payment in a series of payments hereunder shall be deemed to be a separate payment for purposes of Section 409A of the Code.

(c) To the extent that any right to reimbursement of expenses or payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A of the Code), (i) any such expense reimbursement shall be made by the Company no later than the last day of the taxable year following the taxable year in which such expense was incurred by Executive, (ii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect.

(d) While the payments and benefits provided hereunder are intended to be structured in a manner to avoid the implication of any penalty taxes under Section 409A of the Code, in no event whatsoever shall the Company be liable for any additional tax, interest, or penalties that may be imposed on Executive as a result of Section 409A of the Code or any damages for failing to comply with Section 409A of the Code (other than for withholding obligations or other obligations applicable to the Company, if any, under Section 409A of the Code).

Section 13. Review by Counsel. Executive affirms that, before the execution and delivery of this Agreement, Executive has read and understood this Agreement and its legal affects and has reviewed them with counsel of his choice.

Section 14. Conditional Upon Closing of Transaction. The effectiveness of this Agreement shall be conditioned upon the Closing. In the event that the Merger Agreement terminates prior to Closing, this Agreement shall be void ab initio.
