Exhibit 10.4

April 18, 2021

Mr. Luis Massiani

At the address on file with the Company

Dear Luis:

This retention agreement (this “Retention Agreement”) memorializes our agreement regarding the terms of your employment with, and service to, Webster Financial Corporation (the “Company”) following the completion of the merger (the “Merger”) contemplated by the Agreement and Plan of Merger between Sterling Bancorp (“Sterling”) and the Company, dated as of April 18, 2021 (the “Merger Agreement”). Capitalized terms used but not defined in this Retention Agreement have the meanings ascribed to them in the Merger Agreement.

1. Term

The term of this Retention Agreement will commence on the Closing Date and end on the second anniversary of the Closing Date (the “Term”). If your employment with Sterling and Sterling National Bank terminates for any reason before the Closing or the Merger Agreement is terminated before the Closing in accordance with its terms, this Retention Agreement will automatically terminate and be of no further force or effect, and neither of the parties will have any obligations hereunder. By signing this Retention Agreement, you are agreeing that, effective as of the Closing Date, your Employment Agreement with Sterling and Sterling National Bank, dated as of April 3, 2019 and effective on January 1, 2019 (the “Employment Agreement”) will terminate and be of no force or effect.

2. Position; Reporting; Duties; Location

During the Term, you will serve as the Company’s and the Surviving Bank’s Executive Vice President and Chief Operating Officer, reporting directly to the Chief Executive Officer of the Company and the Surviving Bank, and you will have the duties and authority commensurate with your position as Chief Operating Officer of a public company.

Your duties during the Term will be performed primarily at the Company’s headquarters in Stamford, Connecticut, with the ability to use the offices at other campuses of the Company from time to time, and subject to reasonable business travel. You agree that you will be subject to the Company’s and Bank’s policies applicable to similarly situated executives as in effect from time to time, including the Codes of Ethics and Conduct and stock ownership guidelines.

3. Compensation

Annual Base Salary. During the Employment Period, your annual base salary (“Annual Base Salary”) will be $750,000, payable to you in accordance with the Company’s payroll policies. Your Annual Base Salary will be reviewed annually by the Compensation Committee of the Board (the “Compensation Committee”) and may be increased but not decreased. The term Annual Base Salary as utilized in this Retention Agreement will refer to Annual Base Salary as in effect from time to time.

Annual Cash Incentive Award Opportunity. During each year of the Employment Period, you will be eligible to earn an annual cash incentive award with a target opportunity of 100% of Annual Base Salary (the “Target Incentive Payment”), which will be determined by the Compensation Committee of the Board and payable in accordance with the annual cash incentive plan applicable to other senior executives of the Company. Notwithstanding the foregoing, if the Closing Date occurs in the 2021 fiscal year, your 2021 incentive award will be at least equal to the amount you would have earned under the applicable Sterling incentive plan based on actual performance using reasonable assumptions through the end of such year, and be reduced by any pro rata incentive amount paid to you upon Closing for the portion of the 2021 fiscal year prior to the Closing Date.

Equity Compensation Opportunity. During each year of the Employment Period (commencing with the 2022 grant cycle, assuming you have not received a grant in respect of 2022 prior to the Closing Date), you will be granted annual long-term incentive awards with a target grant date fair value of 200% of Annual Base Salary. The grant timing, form and terms and conditions of your long-term incentive awards will be as determined by the Compensation Committee of the Board and no less favorable than those applicable to other senior executives of the Company.

Benefits; Expense Reimbursement. You will be entitled to employee benefits and perquisites on terms that are no less favorable than those provided to other senior executives of the Company, as in effect from time to time. The Company will reimburse your reasonable and documented business expenses in accordance with the Company’s business reimbursement policy applicable to other senior executives of the Company.

Company Change in Control Agreement; Company Non-Competition Agreement. Following the Term, you will enter into (1) a change in control agreement with the Company providing for severance benefits with a multiple of two in the event of a change in control of the Company occurring after the expiration of the Term and (2) a non-competition agreement with the Company providing for severance benefits with a multiple of one in the event of a termination not in connection with a change in control of the Company after the expiration of the Term, in each case substantially consistent with the forms applicable to other senior executives of the Company as then in effect.

Indemnification. The Company will indemnify you (including, for the avoidance of doubt, by providing you with advancement of expenses) to the fullest extent permitted by law against any actual or threatened action, suit or proceeding and provide you with directors’ and officers’ insurance coverage, in each case, with respect to your services as an executive officer and director of the Company and the Bank, on terms no less favorable than those applicable to any other executive officers and directors of the Company and the Bank. In addition, you will continue to have the indemnification and directors’ and officers’ coverage set forth in Section 6.7 of the Merger Agreement.

4. Termination of Employment other than for Cause, Death, or Disability or for Good Reason

If, during the Term, the Company terminates your employment other than for Cause (as defined below) and other than by reason of your death or disability (as defined in the Company’s long-term disability plan or policy that covers you), or you resign your employment with Good Reason (as defined below), the Company shall pay or provide to you the following:

(1)

as soon as reasonably practicable following the Date of Termination (as defined below) and in no event later than 30 days thereafter, (A) a lump sum cash payment consisting of any (i) accrued Annual Base Salary, (ii) any annual cash incentive award earned by you and awarded by the Compensation Committee for a completed fiscal year (with any portion of such incentive award that was previously deferred to be paid in accordance with the applicable deferral arrangement and any election thereunder), (iii) unused vacation accrued through the Date of Termination, and (iv) any unreimbursed expenses incurred through the Date of Termination that are subject to reimbursement pursuant to the Company’s policies, in each case to the extent unpaid (the “Accrued Obligations”), and (B) to the extent not theretofore paid or provided, any other amounts or benefits required to be paid or provided or which you are eligible to receive under any plan, program, policy, practice, contract, or agreement of the Company through the Date of Termination, with any amounts or benefits that constitute non-qualified deferred compensation under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), including the applicable regulations thereunder (“Section 409A”) to be paid or settled at the earliest permissible date for purposes of Section 409A (collectively, the “Other Benefits”);

(2)

a lump sum cash payment equal to the product of (A) the sum of the Annual Base Salary and Target Incentive Payment and (B) three, paid as soon as reasonably practicable after the Release (as defined below) effective date (without revocation by you) and no later than the 60th calendar day following the Date of Termination;

(3)

a prorated annual cash incentive award for the fiscal year in which the Date of Termination occurs based upon the period of time elapsed during such fiscal year prior to the Date of Termination, calculated on a basis no less favorable than is applicable to other senior executives of the Company and assuming that any individual performance goals are satisfied in full, payable at the time that annual incentive awards are paid to other senior executives of the Company (with any portion of such incentive award that was previously deferred to be paid in accordance with the applicable deferral arrangement and any election thereunder);

(4)

a lump sum equal to the product of (A) the sum of (x) the annual premium for coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 in effect as of the Date of Termination for the level of coverage in effect for you under the Company’s group health plan and (y) the annual premium for coverage (based on the rate paid by the Company for active employees) under the Company’s life insurance plans and (B) three, paid as soon as reasonably practicable after the Release effective date (without revocation by you) and no later than the 60th calendar day following the Date of Termination (the “Benefits Continuation Payment”);

(5)

the amount equal to the sum of all Company contributions to which you are eligible as of immediately prior to the Date of Termination under the Company’s qualified defined contribution plans and any excess or supplemental defined contribution plans that you would be eligible to receive as if your employment continued for three years after the Date of Termination, assuming for this purpose that (A) your benefits under such plans are fully vested, (B) your eligible compensation for purposes of such plans in each of the three years is that set forth in Section 3 of this Retention Agreement and that such amounts are paid in equal monthly installments over such three-year period, (C) to the extent that the Company contributions are determined based on your deferrals, that your contribution or deferral elections, as appropriate, are those in effect immediately prior to the Date of Termination, and (D) to the extent that the Company contributions are discretionary, assuming such contributions are made at the rate of any discretionary contributions made by the Company during the plan year immediately preceding the Date of Termination, paid as soon as reasonably practicable after the Release effective date (without revocation by you) and no later than the 60th calendar day following the Date of Termination; and

(6)

any outstanding long-term incentive awards granted to you will vest in full with respect to any service vesting requirement, with any performance-vesting awards to remain outstanding and be eligible to be earned based on the level of performance achieved as determined on a basis no less favorable than that applicable to other senior executives of the Company, as if you had remained employed for the full performance period, without proration and without regard to any applicable one year holding period, and with any such vested awards that constitute deferred compensation subject to Section 409A to be settled at the earliest permissible date for purposes of Section 409A.

The payments and benefits provided under this Section 4 (other than the Accrued Obligations and the Other Benefits) are subject to your: (i) execution, delivery to the Company, and non-revocation within the period after the Date of Termination specified in a release of claims substantially in the form attached hereto as Exhibit A (the “Release”). In the event you breach the terms of Section 5, all payments and benefits provided under this Section 4 (other than the Accrued Obligations and the Other Benefits) will, to the extent unpaid, be subject to forfeiture by you and, to the extent paid, be subject to clawback and recoupment by the Company.

For purposes of this Retention Agreement and your outstanding equity awards granted prior to, on or after the Closing Date, the following terms shall have the meanings set forth below:

“Cause” means your failure or refusal to substantially perform your duties hereunder (after notice from the Company and a reasonable opportunity to cure), willful misconduct, breach of fiduciary duty involving personal profit, breach of the Company’s or the Bank’s Code of Ethics, material violation of the Sarbanes-Oxley requirements for officers of public companies that in the reasonable opinion of the Board will likely cause substantial financial harm or substantial injury to the reputation of the Company or the Bank, willfully engaging in actions that in the reasonable opinion of the Board will likely cause substantial financial harm or substantial injury to the business reputation of the Company or the Bank, willful violation of any law, rule or regulation (other than routine traffic violations or similar offenses) or final cease-and-desist order, or material breach of any provision of this Retention Agreement. The cessation of your employment shall not be deemed to be for Cause unless and until there shall have been delivered to you a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters of the entire membership of the Board at a meeting of the Board called and held for such purpose (after reasonable notice is provided to you and you are given an opportunity with your counsel to be heard before the Board), finding that, in the good faith opinion of the Board, you are guilty of the conduct constituting Cause, and specifying the particulars thereof in detail. For purposes hereof, no act or failure to act, on your part, shall be considered “willful” unless it is done, or omitted to be done, by you in bad faith or without reasonable belief that your action or omission was in the best interests of the Company and the Bank. Any act, or failure to act, based upon the direction of the Board or the Bank Board or the advice of counsel for the Company or the Bank shall be conclusively presumed to be done, or omitted to be done, by you in good faith and in the best interests of the Company or the Bank.

“Date of Termination” means the date of your termination of employment with the Company and its affiliates.

“Good Reason” means the occurrence of any of the following events without your consent: (1) a material reduction of any element of the compensation required to be provided to you in accordance with any of the provisions of this Retention Agreement; (2) a material adverse change in your title or duties with the Company and the Bank from those set forth in this Retention Agreement, which change would cause your position to become one of materially lesser responsibility, importance or scope; (3) the Company requiring you to be based at any office or location other than as provided in this Retention Agreement resulting in an increase in your commute of 50 miles or more; or (4) a material breach of this Retention Agreement by the Company or the Bank. Notwithstanding the foregoing, no such event shall constitute “Good Reason” unless (a) you shall have given written notice of such event to the Company within 90 days after the initial occurrence thereof, (b) the Company and the Bank shall have failed to cure the situation within 30 days following the delivery of such notice (or such longer cure period as may be agreed upon by the parties) (the “Cure Period”), and (c) you terminate employment within 30 days after expiration of such Cure Period. For the avoidance of doubt, you hereby agree that the termination of the Employment Agreement or the changes in the terms and conditions of your employment from those in effect immediately prior to the Closing Date shall not constitute a basis to terminate your employment for Good Reason under this Retention Agreement or otherwise.

5. Restrictive Covenants

A. General

You acknowledge that the restrictions of this Section 5, including, without limitation, the scope and duration of such restrictions, are reasonable and necessary to protect the legitimate business interests of the Company. In view of your importance to the success of the Merger, if you compete with the Company after your services with the Company cease, the Company will likely suffer significant and irreparable harm. For purposes of this Section 5, all references to the Company shall include the Company, Sterling or any of their respective affiliates, including their predecessor and successor entities, and the scope of any such restrictions shall relate to the business of the Company, including Sterling, as it exists prior to, on or after the Closing Date.

B. Confidential Information

While providing services to the Company and thereafter, you shall hold in a fiduciary capacity for the benefit of the Company all secret or confidential information, knowledge or data relating to the Company and its businesses, which shall have been obtained by you during your service with the Company and which shall not be or become public knowledge (other than by acts by you or representatives of you in violation of this Retention Agreement). After termination of your services with the Company for any reason, you shall not, without the prior written consent of the Company, (1) communicate or divulge any such information, knowledge or data to anyone other than the Company and those designated by it; or (2) use to your advantage or to the detriment of the Company any such information, knowledge or data. The restrictions in this Section 5.B shall not apply to any information to the extent that you are required to disclose such information by law; provided that you (x) notify the Company of the existence and terms of such obligation; (y) give the Company a reasonable opportunity to seek a protective or similar order to prevent or limit such disclosure; and (z) disclose only that information actually required to be disclosed. Notwithstanding any provision of this Retention Agreement to the contrary, nothing contained herein is intended to, or shall be interpreted in a manner that does, limit or restrict you from exercising any legally protected whistleblower rights (including pursuant to Rule 21F under the Securities Exchange Act of 1934). At the end of your provision of services to the Company, you shall return to the Company all confidential information in any form (including all copies and reproductions thereof) and all other property whatsoever of the Company in your possession or under your control.

C. Non-Solicitation/No Hire of Employees

During the period of your service with the Company and the additional period ending on the date that is one year after the date of termination of your service with the Company in all capacities for any reason (the “Non-Solicitation Period”), you shall not, without the prior written consent of the Company, directly or indirectly, in any manner, on your own behalf or on behalf of any other person, corporation, partnership, firm, institution or other business entity, (1) offer employment (or a consulting, agency,independent contractor or other similar position) to, or otherwise hire, any person who is (or was at any time during the six months prior to such offer or hiring) an employee, consultant, representative, officer or director of the Company, or (2) Solicit (as defined below) any such person to (x) accept employment (or any aforesaid position) with any company or entity with which you are then employed, providing services or otherwise affiliated, or (y) cease his or her relationship with the Company for any reason. This Section 5.C shall not apply to solicitation, recruitment, encouragement, inducement or termination during the period of your service with the Company on behalf of the Company.

D. Non-Solicitation of Clients or Customers

During the Non-Solicitation Period, you shall not, directly or indirectly, in any manner, on your own behalf or on behalf of any other person, corporation, partnership, firm, institution or other business entity, Solicit a Client (as defined below) to (1) transact business with a Competitive Enterprise (as defined below but without regard to the geographic limitations therein), (2) reduce the amount of business that any Client has customarily done or contemplates doing with the Company or (3) cease or refrain from doing business with the Company, or, in any manner, interfere with or damage (or attempt to interfere with or damage) any relationship between the Company and a Client.

E. Non-Competition

During the period of your service with the Company and the additional period ending on the date that is two years after the date of termination of your service with the Company in all capacities for any reason, you shall not, directly or indirectly, in any manner, associate with or provide services to, in any capacity (including, without limitation, as an officer, agent, employee, partner, director, consultant or advisor and whether or not for compensation), any Competitive Enterprise (as defined below). For the avoidance of doubt, the foregoing restrictions shall not restrict you from associating with or providing services in any capacity to a private equity firm, hedge fund or equity sponsor, in each case, provided that you may not engage with, or provide advice or services to, any of the foregoing with respect to investments or potential investments in a Competitive Enterprise that engages in commercial banking or financial services/financial technology activities that are directly competitive with the Company.

F. Cooperation

During the period of your service with the Company in any capacity and following the cessation of your service for any reason, you shall, upon reasonable notice, (1) furnish such information and assistance to the Company, as may reasonably be requested by the Company, with respect to any matter, project, initiative or effort for which you are or were responsible or have relevant knowledge or had substantial involvement in while providing services to the Company, and (2) cooperate with the Company during the course of all third-party proceedings arising out of the Company’s business about which you have knowledge or information; provided, however, that you shall not be required to provide information or assistance with respect to any litigation between you and the Company.

G. Definitions

For purposes of this Retention Agreement, the following terms shall have the meanings set forth below:

(1) “Client” means any client, customer or business relation, whether a person or entity, and whether current, former (within the 12-month period after such relationship has been terminated) or prospective (meaning such person or entity is reasonably anticipated to become a customer or client or commence such business relationship, provided that there are demonstrable efforts or plans to establish such relationship) of the Company.

(2) “Competitive Enterprise” means any person, firm, corporation, other entity or business enterprise in whatever form that engages in, or owns or controls a significant interest in any entity that engages in, (A) the provision of depository, administrative or other services or products relating to health savings accounts, in the Unites States, or (B) any other activity in which the Company is engaged, in the states comprising the New England region or any other state in the United States in which the Company has a business presence (as of your date of termination, in the case of your termination of services with the Company). The activities covered by clause (B) of the previous sentence include, without limitation, the solicitation and acceptance of deposits of money or commercial paper, the solicitation and funding of loans and the provision of other banking services, including business and consumer lending, asset-based financing, residential mortgage funding, mortgage warehouse lending, equipment financing, commercial and residential mortgage lending and brokerage, deposit services (including municipal deposit services), trade financing, the sale of annuities, life and health insurance products, title insurance services, private banking, wealth management and investment advisory services, the sale or servicing of banking and financial products and services, factoring/accounts receivable management services and real estate investment trusts.

(3) “Solicit” means any direct or indirect communication of any kind whatsoever, regardless of by whom initiated, inviting, inducing, advising or encouraging (or attempting to do the foregoing) or requesting, any person or entity, in any manner, to take or refrain from taking any action.

H. Remedies; Judicial Modification

You acknowledge and agree that the terms of this Section 5: (1) are reasonable in light of all of the circumstances, (2) are sufficiently limited to protect the legitimate interests of the Company, (3) impose no undue hardship on you and (4) are not injurious to the public. You further acknowledge and agree that: (x) your breach of the provisions of this Section 5 will cause the Company irreparable harm, which likely cannot be adequately compensated by money damages, and (y) if the Company elects to prevent you from breaching such provisions by obtaining an injunction against you, there is a reasonable probability of the Company’s eventual success on the merits. You consent and agree that if you commit any such breach or threaten to commit any breach, the Company shall be entitled to temporary, preliminary, and/or permanent injunctive relief from a court of competent jurisdiction, without posting any bond or other security and without the necessity of proof of actual damage, in addition to, and not in lieu of, such other remedies as may be available to the Company for such breach, including cessation of its obligation to pay you the compensation and benefits provided under this Retention Agreement, the right to recoup any such compensation or benefits previously paid under this Retention Agreement and the recovery of money damages. If any of the provisions of this Section 5 are determined to be wholly or partially unenforceable, you hereby agree that this Retention Agreement or any provision hereof may be reformed so that it is enforceable to the maximum extent permitted by law, and in the case when such provision is not capable of being reformed, it shall be severed and all remaining provisions of this Retention Agreement shall be enforced. If any of the provisions of this Section 5 are determined to be wholly or partially unenforceable in any jurisdiction, such determination shall not be a bar to or in any way diminish the Company’s right to enforce any such covenant in any other jurisdiction.

I. Jurisdiction

You agree to submit to the exclusive jurisdiction of the courts of the State of Connecticut and the Federal courts of the United States of America located in Connecticut in respect to the interpretation and enforcement of the provisions under this Section 5, and waive as a defense in any action, suit or proceeding for the interpretation or enforcement under this Section 5, that you are not subject thereto or that such action, suit or proceeding may not be brought or is not maintainable in said courts or that this Retention Agreement may not be enforced in or by said courts or that venue is improper.

6. Section 409A.

It is the intent of the parties that the payments and benefits under this Retention Agreement will be exempt from or otherwise comply with the provisions of Section 409A, and each payment under this Retention Agreement will be treated as a separate payment for purposes of Section 409A. In no event may you, directly or indirectly, designate the calendar year of payment. The parties intend that the terms and provisions of this Retention Agreement will be interpreted and applied in a manner that satisfies the requirements and exemptions of Section 409A. All reimbursements of costs and expenses or in-kind benefits provided under this Retention Agreement will be made or provided in accordance with Section 409A, including, where applicable, that the right to reimbursement or in-kind benefits will not be subject to liquidation and may not be exchanged for any other benefit, the amount of expenses eligible for reimbursement (or in-kind benefits paid) in one year will not affect amounts reimbursable or provided as in-kind benefits in any subsequent year, and all expense reimbursements that are taxable income to you will in no event be paid later than the end of the calendar year next following the year in which you incur the expense.

Notwithstanding any other provision of this Retention Agreement to the contrary, if you are considered a “specified employee” for purposes of Section 409A (as determined in accordance with the methodology established by the Company as in effect on the date of termination), any payment that constitutes nonqualified deferred compensation within the meaning of Section 409A that is otherwise due to you under this Retention Agreement during the six-month period following your separation from service (as determined in accordance with Section 409A) on account of your separation from service will be accumulated and paid to you on the first business day of the seventh month following your separation from service (the “Delayed Payment Date”). If you die during the postponement period, the amounts and entitlements delayed on account of Section 409A will be paid to the personal representative of your estate on the first to occur of the Delayed Payment Date or 30 calendar days after the date of your death.

7. Limitation on Payments under Certain Circumstances.

Notwithstanding any other provision of this Retention Agreement, in the event that any payment or benefit received or to be received by you in connection with the Merger or a “change in ownership or control” (within the meaning of Section 280G of the Code) of the Company occurring following the Closing Date (whether pursuant to the terms of this Retention Agreement or any other plan, arrangement or agreement) (collectively, the “Total Benefits”) would be subject to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), the Total Benefits shall be reduced to the extent necessary so that no portion of the Total Benefits is subject to the Excise Tax; provided, however, that no such reduction in the Total Benefits shall be made if by not making such reduction, your Retained Amount (as defined below) would be greater than your Retained Amount if the Total Benefits are so reduced.

All determinations required to be made under this Section 7 shall be made by Golden Parachute Tax Solutions LLC or another mutually agreed nationally recognized certified public accounting firm or other professional organization that is a certified public accounting firm recognized as an expert in determinations and calculations for purposes of Section 280G of the Code selected by the Company prior to a change in control (the “Accounting Firm”), which determinations shall be conclusive and binding on you and the Company absent manifest error. All fees and expenses of Accounting Firm shall be borne solely by the Company. Prior to any reduction in the Total Benefits pursuant to this Section 7, the Accounting Firm shall provide you and the Company with a report setting forth its calculations and containing related supporting information. In the event that any such reduction is required, the Total Benefits shall be reduced in the following order: (i) the Benefits Continuation Payment, (ii) the payment under Section 4(2), (iii) any other portion of the Total Benefits that are not subject to Section 409A (other than the Total Benefits resulting from any accelerated vesting of equity awards), (iv) the Total Benefits that are subject to Section 409A in reverse order of payment, and (v) the Total Benefits that are not subject to Section 409A and arise from any accelerated vesting of equity awards. The parties hereby elect to use the applicable federal rate that is in effect on the date that this Retention Agreement is entered into for purposes of determining the present value of any payments provided for hereunder for purposes of Section 280G of the Code.

For purposes of this Retention Agreement, “Retained Amount” shall mean the present value (as determined in accordance with Sections 280G(b)(2)(A)(ii) and 280G(d)(4) of the Code) of the Total Benefits net of all federal, state and local taxes imposed on you with respect thereto. In connection with making determinations under this Section 7, the Accounting Firm shall take into account the value of any reasonable compensation for services to be rendered by you before or after the change in ownership or control, including the noncompetition provisions set forth in this Retention Agreement or that may otherwise apply to you, and the Company shall cooperate in the valuation of any such services, including any noncompetition provisions.

8. Miscellaneous.

This Retention Agreement is personal to you and, without the prior written consent of the Company, shall not be assignable by you. This Retention Agreement and any rights and benefits hereunder will inure to the benefit of and be enforceable by your legal representatives, heirs, or legatees. This Retention Agreement and any rights and benefits hereunder will inure to the benefit of and be binding upon the Company and its successors and assigns.

The Company may withhold from any amounts payable under this Retention Agreement such federal, state, local, or foreign taxes as shall be required to be withheld pursuant to any applicable law or regulation.

The Company’s obligation to make the payments provided for in this Retention Agreement and otherwise to perform its obligations hereunder will not be affected by any set-off, counterclaim, defense, or other claim, right, or action that the Company or its subsidiaries or affiliates may have against you or others, except as provided in this Retention Agreement related to compliance with the covenants in Section 5. In no event will you be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to you under any of the provisions of this Retention Agreement, and such amounts will not be reduced regardless of whether you obtain other employment.

Upon the expiration or termination of this Retention Agreement or your services, the respective rights and obligations of the parties hereto, including your obligations under Section 5, shall survive such expiration or termination consistent with the terms of this Retention Agreement and otherwise to the extent necessary to carry out the intentions of the parties hereunder.
