GENERAL INFORMATION

Introduction

This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors of Enterprise Bancorp, Inc. (the “Company”), the parent holding company of Enterprise Bank and Trust Company (the “Bank”), for the 2018 Annual Meeting of Stockholders of the Company (the “Annual Meeting”), to be held on Tuesday, May 1, 2018, at 3:30 p.m. local time, at the UMass Lowell Inn and Conference Center, 50 Warren Street, Lowell, Massachusetts 01852 and at any adjournments or postponements thereof. This Proxy Statement, the accompanying Notice of Annual Meeting and the accompanying proxy card are first being mailed to stockholders on or about April 2, 2018.

The Annual Meeting has been called for the following purposes: (1) to elect six Directors of the Company, each to serve for a three-year term (“Proposal One”); (2) to vote on the ratification of the Audit Committee’s appointment of RSM US LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2018 (“Proposal Two”); and (3) to transact such other business as may properly come before the meeting or any adjournments or postponements thereof.

Record Date

The Board of Directors has fixed the close of business on March 2, 2018 as the record date for the determination of stockholders entitled to notice of, and to vote at, the Annual Meeting and any adjournments or postponements thereof (the “Record Date”). Only holders of record of the Company’s common stock (the “Common Stock”) at the close of business on the Record Date will be entitled to vote. At the close of business on the Record Date, there were 11,635,044 shares of the Common Stock issued and outstanding. The holders of shares of the Common Stock outstanding as of the close of business on the Record Date will be entitled to one vote for each share held of record upon each matter that may properly come before the Annual Meeting or any adjournments or postponements thereof.

Proxies

If you are the record holder of your shares (i.e., you hold your shares in your own name with our transfer agent, as opposed to through a bank, broker or other nominee), you may vote at the Annual Meeting in person or by proxy. Proxies may be delivered electronically via the Internet, by telephone, or in writing by mail. If you intend to deliver a proxy electronically or by phone, you may do so by following the instructions included with your proxy card.

If you hold your shares in “street name,” such as in a stock brokerage account or through a bank or other nominee, such bank, broker or other nominee should provide you with these proxy materials, including a voting instruction card. If you hold your shares in “street name” and have not received these proxy materials, including a voting instruction card, from your bank, broker or other nominee, please contact the institution that holds your shares. As a street name stockholder, you may also be eligible to vote your shares via the Internet or by telephone by following the voting instructions provided by the bank, broker or other nominee that holds your shares, using either the Internet address or the toll-free telephone number provided on the voting instruction card (if the bank, broker or other nominee provides these voting methods). Otherwise, please complete, sign and date the voting instruction card and return it promptly.

If you vote electronically or by telephone and you properly follow the instructions included with your proxy card for doing so by no later than the deadline indicated in such instructions or if you vote by mail and you return to the Company the enclosed proxy card properly executed in time to be voted at the Annual Meeting, then the shares represented by your proxy, regardless of the method of delivery, will be voted in accordance with your voting instructions, unless you subsequently revoke your proxy as further explained below.

If you properly deliver your proxy without including any instructions as to how your proxy should be voted, then your proxy will be voted as follows: (1) FOR the election of Gino J. Baroni, John P. Clancy, Jr., James F. Conway, III, John T. Grady, Jr., Mary Jane King and Shelagh E. Mahoney, as the six nominees of the Board of Directors, as Directors of the Company; (2) FOR the ratification of the Audit Committee’s appointment of RSM US LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2018; and (3) in such manner as the proxy holders decide on such other matters as may properly come before the Annual Meeting or any adjournments or postponements thereof.

The presence of a stockholder at the Annual Meeting will not automatically revoke a stockholder’s proxy. A stockholder may, however, revoke a proxy at any time before such proxy is voted at the Annual Meeting by filing with the Secretary of the Company a written notice of revocation, by delivering to the Company a duly executed proxy bearing a later date, or by properly delivering a proxy electronically or by telephone at a later date. All written notices of revocation and other written communications with respect to revocation of proxies in connection with the Annual Meeting should be addressed as follows: Enterprise Bancorp, Inc., 222 Merrimack Street, Lowell, Massachusetts 01852, Attention: Michael A. Spinelli, Secretary.

It is not anticipated that any matters other than those set forth in Proposals One and Two will be brought before the Annual Meeting. The Company has not received any proper proposals from its stockholders to be included in this Proxy Statement or otherwise brought before the Annual Meeting. Please see the additional information under the heading “Stockholder Proposals” on pages 44-45 of this Proxy Statement for a description of the requirements that must be satisfied in order for any Director nomination or other stockholder proposal, which is not otherwise included in this Proxy Statement, to be presented by any stockholder at the Annual Meeting. If any other matters properly come before the Annual Meeting, the persons named as proxies will vote upon such matters in their discretion in accordance with their best judgment.

In addition to use of the mails, proxies may be solicited personally or by telephone, fax or e-mail by officers, Directors and employees of the Company, none of whom will be specially compensated for such solicitation activities. Arrangements will also be made with brokerage houses and other custodians, nominees and fiduciaries for forwarding solicitation materials to the beneficial owners of shares held of record by such persons, and the Company will reimburse such persons for their reasonable out of pocket expenses incurred in connection with that solicitation. The cost of soliciting proxies will be borne by the Company.

Quorum; Vote Required

The presence, in person or by proxy, of at least a majority of the total number of outstanding shares of the Common Stock is necessary to constitute a quorum at the Annual Meeting for the transaction of business. Abstentions, withheld votes and shares held by a bank, broker or other nominee that are voted on any matter will be counted as present for purposes of determining the presence or absence of a quorum for the transaction of business at the Annual Meeting.

The number of affirmative votes required for approval of the matters to be considered at the Annual Meeting is as follows:


•	Proposal One - Election of Class of Directors

Each Director is required to be elected by a majority of the votes cast by stockholders present, in person or by proxy, at the Annual Meeting. At the Annual Meeting, the maximum number of Directors to be elected is six.


•	Proposal Two - Ratification of Appointment of Independent Registered Public Accounting Firm

The ratification of the appointment of RSM US LLP as our independent registered public accounting firm for 2018 requires that the votes cast by stockholders present, in person, or by proxy, at the Annual Meeting favoring the ratification exceed the votes cast by stockholders present, in person or by proxy, at the Annual Meeting opposing the ratification.

In voting for the election of Directors, you may vote “FOR” all nominees or “WITHHOLD” your vote from all nominees or from only certain specified nominees. Withholding a vote from all or some of the nominees is effectively a vote against such nominee(s).

In voting for the ratification of the appointment of RSM US LLP as our independent registered public accounting firm for 2018, you may vote “FOR” or “AGAINST” such ratification or you may “ABSTAIN” from voting on the matter. Under Massachusetts law, an abstention is not considered a vote cast at a meeting and, consequently, abstentions will have no effect on the voting for this proposal.

Under existing stock exchange rules, banks, brokers, or other nominees may vote shares held for a customer in street name on matters that are considered to be “routine” even if they have not received voting

instructions from their clients. A broker “non-vote” occurs when a bank, broker, or other nominee has not received voting instructions from a customer and does not vote the customer’s shares either because the matter is not considered routine or because the bank, broker or other nominee does not exercise its prerogative to vote even if the matter is considered routine.

Proposal One, namely the election of Directors, is not considered a “routine” matter, which means that if your shares are held in street name, your bank, broker, or other nominee may not vote your shares on this matter unless you provide timely instructions for such voting. Proposal Two, namely the ratification of the appointment of the independent registered public accounting firm, is considered a “routine” matter, which means that if your shares are held in street name your bank, broker, or other nominee may vote your shares on this matter in its sole discretion if you do not provide timely instructions for voting your shares. Broker non-votes will have no effect on the voting for Proposals One and Two.

The Directors and executive officers of the Company have indicated that they intend to vote all shares of the Common Stock that they are entitled to vote in favor of Proposals One and Two. On the Record Date, the Directors and executive officers of the Company in the aggregate had the right to vote 2,127,514 shares of the Common Stock, representing approximately 18.29% of the outstanding shares of the Common Stock as of such date.

PROPOSAL ONE

ELECTION OF CLASS OF DIRECTORS

The Company’s Amended and Restated By-Laws (the “By-Laws”) provide that the number of Directors shall be set by a majority vote of the entire Board of Directors. Currently, the number of Directors for the Company is set at 19. Under the Company’s Restated Articles of Organization and By-Laws, this number is divided into three classes, as nearly equal in number as possible, with the Directors in each class serving a term of three years and until their respective successors are duly elected and qualified, or until his or her earlier resignation, death or removal. As the term of one class expires, a successor class is elected at the annual meeting of stockholders for that year.

At the Annual Meeting, there are six Directors to be elected to serve until the 2021 Annual Meeting of Stockholders and until their respective successors are duly elected and qualified, or until his or her earlier resignation, death or removal. The Board of Directors has nominated, upon the recommendation of the Board’s Corporate Governance/Nominating Committee, each of Gino J. Baroni, John P. Clancy, Jr., James F. Conway, III, John T. Grady, Jr., Mary Jane King and Shelagh E. Mahoney, for election as a Director for a three-year term.

The Board of Directors believes that all of the nominees will stand for election and will serve as a Director if elected. However, if any nominee fails to stand for election or is unable or refuses to accept election, the proxies will be voted for the election of such other person or persons as the Board of Directors may recommend. Alternatively, in lieu of designating a substitute, the Board of Directors may reduce the number of Directors.

PROPOSAL TWO

RATIFICATION OF APPOINTMENT OF INDEPENDENT

REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has appointed RSM US LLP to serve as the independent registered public accounting firm of the Company for the year ending December 31, 2018.

While the Company is not required to submit the ratification of the Audit Committee’s appointment of the Company's independent registered public accounting firm to a vote of stockholders, the Board considers the selection of the independent registered public accounting firm to be an important matter and is therefore submitting the selection of RSM US LLP for ratification by stockholders as a matter of good corporate practice.

In the event a majority of the votes cast are against the ratification of the appointment of RSM US LLP, the Audit Committee may consider the vote and the reasons therefore in future decisions of its appointment of the Company’s independent registered public accounting firm. Even if the appointment is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time if it is determined that such a change would be in the best interests of the Company.

Representatives of RSM US LLP are expected to attend the Annual Meeting at which time they will have an opportunity to make a statement if they wish to do so and will be available to answer any appropriate questions from stockholders.

The following table sets forth the fees paid or accrued by the Company for professional services provided by the Company’s independent registered public accounting firms, RSM US LLP and KPMG LLP.



	2017	2016
Audit Fees - RSM	$334,750	$319,000
Additional Audit Fees - RSM	$6,500	$0
Additional Audit Fees - KPMG	$80,000	$130,000
Audit-Related Fees - KPMG	$0	$10,000
Tax Related Fees - RSM	$63,341	$33,075
Totals	$484,591	$492,075

Audit Fees

Fees billed for professional services rendered for the audit of the Company’s annual consolidated financial statements on Form 10-K and the review of the consolidated financial statements included in the Company’s quarterly reports on Form 10-Q as filed with the SEC during the year.

Additional Audit Fees

Additional audit fees paid or accrued for consents related to certain of the Company’s SEC filings which referenced prior year audited financial statements.

Audit-Related Fees

The audit-related fees billed by KPMG LLP to the Company in 2016 were related to the change in independent registered public accounting firms for the 2016 fiscal year.

Tax Fees

Fees billed for tax preparation services performed in each of these two years by RSM US LLP.

All Other Fees

No additional fees were paid to RSM US LLP or KPMG LLP in 2017 and 2016.

The Audit Committee must approve in advance any audit or permissible non-audit engagement or relationship between the Company and its independent registered public accounting firm. The Audit Committee has delegated to its chairman this approval authority, subject to the requirement that the chairman report the terms of any such engagement or relationship to the full Audit Committee at its next regularly scheduled meeting. All of the services described above, including those described under the headings, “Audit-Related Fees,” “Tax Fees,” and “All Other Fees” were provided in conformance with such pre-approval requirements. The Audit Committee has determined that providing the services described above under the headings “Audit-Related Fees,” “Tax Fees,” and “All Other Fees” is compatible with maintaining the independence of RSM US LLP and KPMG LLP.

Recommendation of Directors

The Board of Directors recommends that the stockholders vote FOR Proposal Two.

(1)	All of the listed Directors are also Directors of the Bank. The years listed in the foregoing table are the respective years in which each named individual first became a Director of the Company and the Bank or, if prior to the Company’s formation in 1996, of the Bank.

Independence of Board of Directors

The Board of Directors has determined that Directors Baroni, Clementi, Conway, Cowan, Grady, King, Koutsos, Lerner, Mahoney, Moloney, Pedroso, Putziger, Reid and Spinelli were “independent” of the Company’s management as of the date of this Proxy Statement, on the basis of the independence standards contained in Rule 5605(a)(2) of the Marketplace Rules of The NASDAQ Stock Market. Messrs. Duncan, Main and Clancy, who are all current employees of the Company, Mr. Ansin who is a former employee of the Company and Mr. Deschene as further described below were determined not to be independent of the Company.

In determining the independence of Mr. Deschene, the Board considered the cross-representation of Directors who serve on both the boards of Mr. Deschene’s employers, Wellforce and Circle Health, and the Company. Mr. Clancy currently serves on the board of directors of Wellforce which is responsible for approving the compensation for Mr. Deschene. Primarily due to this cross representation, Mr. Deschene has not been deemed independent.

Board Leadership Structure and the Board’s Role in Risk Oversight

Mr. Duncan, who through December 31, 2006 served as the Company’s Chief Executive Officer, serves as the Executive Chairman of the Board and Mr. Clancy serves as the Chief Executive Officer of the Company. The Board has implemented this structure in order to enhance succession planning for Company management while recognizing the individual roles and responsibilities of the Chief Executive Officer and Executive Chairman and taking into consideration the size, growth potential and complexity of the Company’s operations.

The Board of Directors annually appoints a Chairman, Vice Chairman, and Secretary. These Board offices are currently held by Mr. Duncan as Chairman, Mr. Conway as Vice Chairman and Mr. Spinelli as Secretary. The Board of Directors also appoints an independent Lead Director. As Lead Director, Mr. Conway presides over executive sessions of independent Directors. In addition to these offices, the Board of Directors maintains active committees to which specific risk oversight responsibilities have been delegated by the Board. Committee chairpersons and members are elected each year by the Board to a one-year term.

Regular meetings of the Board and its committees are held to review strategy, policy and results of operations, including discussions of risk. The frequency of meetings is determined by, among other things, strategy, operations and the number and significance of risk matters that are discussed at either the Board or committee meetings. Each committee chairperson is provided an opportunity to present a report to the full Board at each regularly scheduled Board meeting and is required to provide a full report of past accomplishments and future strategies to the full Board on an annual basis.

The Board of Directors is responsible for oversight of the Company’s risk management. The Chief Executive Officer, the Company’s Executive Vice President-Chief Risk Officer and other members of senior management provide regular reports to the Board on the Company’s management of risk. Additionally, on a semi-annual basis, the Company’s Chief Risk Officer reports to the Board of Directors on the effectiveness of the Company’s risk management program.

Meetings of Board of Directors and Committees

There were nine meetings of the Board of Directors during the year ended December 31, 2017. During such period, each Director attended more than 75% in the aggregate of the total number of meetings of the Board of Directors and of each of the committees of the Board of Directors on which he or she served.

A description of the functions and responsibilities of each committee of the Board of Directors is set forth below.

Audit Committee. The Audit Committee consists solely of independent Directors and assists the Board in its general oversight of our financial reporting, financial risk assessment, internal controls, and audit functions, and is directly responsible for the appointment, compensation, retention and oversight of the work of the Company’s independent registered public accounting firm and the Company’s Director of Internal Audit. The committee meets quarterly with RSM US LLP and management to review our interim financial results, and to discuss various topics and events that may have significant financial impact, before the publication of quarterly earnings news releases.

Among other responsibilities, the committee also monitors: the adequacy of internal controls relating to financial reporting, compliance by the Company with commercial and consumer legal and regulatory requirements, compliance with fair lending and community reinvestment activities, management of relationships with third party service providers, the qualifications and independence of the Company’s independent registered public accounting firm, performance of the Company’s Internal Audit Director and independent registered public accounting firm, the business conduct and ethical standards of the Company, and the treatment of complaints received by management regarding accounting, internal accounting controls, or auditing matters. The Board of Directors has determined that Carol Reid, Audit Committee Chair, who is one of the six independent Directors serving on the committee, qualifies to serve as an Audit Committee Financial Expert (as such term is defined under applicable SEC rules). The committee operates under a written charter, a copy of which can be found on the Company’s website (www.enterprisebanking.com).

In determining the independence of the Audit Committee members, the Board of Directors has used, as

required for a company with shares listed on the NASDAQ Global Market, the definition of independence contained in Section 5605(a)(2) of the Marketplace Rules of The NASDAQ Stock Market as well as the additional independence requirements contained in Section 10A(m)(3) of the Securities Exchange Act of 1934, as amended, and Rule 10A-3(b)(1) of the SEC, and has applied such definition and additional criteria consistently to all members of the Audit Committee.

Compensation Committee. The Compensation Committee consists solely of independent Directors and “Non-Employee Directors” (as defined by Rule 16b-3 of the Securities Exchange Act of 1934, as amended) and is responsible for establishing the Company’s compensation philosophy and executive compensation standards, performing the annual Chairman evaluation and recommending executive compensation, any employment agreements and Director compensation to the Board for approval. The committee is also responsible for overseeing the administration of the Company’s employee benefit, incentive and compensation programs, determining the effectiveness of the Company's compensation-related risk management practices, and reviewing and approving the Chief Executive Officer succession plan, and recommending such plan to the Board of Directors for approval. The committee operates under a written charter, a copy of which can be found on the Company’s website (www.enterprisebanking.com). See “Compensation Committee Matters” for further information on the Compensation Committee.

Corporate Governance/Nominating Committee. The Corporate Governance/Nominating Committee consists solely of independent Directors and is responsible for establishing effective governance controls and procedures for the Company and its Directors. The committee’s specific responsibilities include recommending to the Board its determination of the independence of each Director, the composition of each Board committee, nominees for each Board committee chairperson, the Company’s response to any stockholder proposals, nominees for election to the Board of Directors, and the appointment of Board officers. The committee is also responsible for monitoring the effectiveness and performance of the Board and its various committees. The committee operates under a written charter, a copy of which can be found on the Company’s website (www.enterprisebanking.com).

Banking Technology Steering Committee (“BTSC”). BTSC is responsible for overseeing the information security program, project management, the protection of customer data, responses to breaches of customer data, and other technology, information security and cyber security related functions of the Bank. In addition, the committee reviews the adequacy of the Company’s business continuity and disaster recovery plans and the deployment of new technologies with particular attention to operational risk management, and determines the appropriateness of acceptable operating risks that have been identified by management. The committee monitors the results of third

party testing and risk assessments as part of the Company’s ongoing efforts to maintain a secure operating environment.

Enterprise Wealth Management Committee (“EWMC”). EWMC is responsible for overseeing that prudent care and discretion are followed in the investment and fiduciary oversight of client assets to properly manage and report client and Bank market risk exposures. The committee is responsible for approving general investment standards and the selection of independent investment advisors and for monitoring investment, advisor and portfolio performance. The committee periodically reviews management’s strategic planning initiatives and direction for the wealth management services provided under the Enterprise Wealth Management label and is also responsible for the oversight of the sale of non-deposit investment (i.e., brokerage) products through Enterprise Wealth Services using an independent third-party broker.

Executive Committee. The Executive Committee is appointed by the Board to assist the Board in fulfilling its responsibilities pertaining to the oversight of management of the Company. The committee is responsible for reviewing and discussing corporate matters, as identified by the Board of Directors and/or Executive Management, and recommending appropriate actions.

Loan Committee. The Loan Committee reviews information and reports relating to the composition, status, delinquency and classification of consumer, residential, construction and commercial loans within the Bank’s loan portfolio as well as any non-performing and past due loans and/or OREO assets (i.e., foreclosed property held by the Bank). The committee also reviews certain larger construction lending projects and relationships and reviews stress testing to determine potential risk exposure(s) related to the commercial real estate portion of the loan portfolio. The overall mission of the committee is to monitor the trends in asset and credit quality of the Bank’s loan portfolio as well as various other internal and external factors and controls that may impact loan growth, quality, concentration risk and overall credit risk exposure. In addition to these duties, the committee is responsible for reviewing the results of third party loan review and stress testing engagements, monitoring non-performing past due loans and the adequacy of the allowance for loan losses, including the methodology applied to calculate the level of the allowance for loan losses. The committee not only identifies and informs the Board of any unfavorable trends that it may detect in the Bank’s loan portfolio, but also recommends actions that may be taken to mitigate portfolio risk reviewing and approving charge-offs. The committee regularly reviews and makes recommendations on the adequacy of the allowance for loan losses. The Loan Committee is responsible for approving and/or ratifying loans above certain limits and overseeing the credit quality of the loan portfolio.

Strategic Planning Committee. The Strategic Planning Committee oversees strategic planning activities in the areas of: geographic branch expansion, opportunities to diversify revenue streams, the potential acquisition of expansion of business lines, and the critical analysis of existing business lines. Working with management, outside consultants and banking industry experts, the committee assesses market and industry conditions in an effort to identify future opportunities, risks, necessary evolution and changes for the Company and the Bank. The committee is also responsible for coordinating an annual board strategic planning session and for setting the general strategic direction and focus of the Company.

Code of Business Conduct and Ethics

The Company has adopted a Code of Business Conduct and Ethics that sets forth standards of ethical business conduct for all directors, officers, and employees of the Company and its subsidiaries. The purpose of the Code of Business Conduct and Ethics is to provide directors, officers, and employees with a framework to make honest,

ethical, and legal decisions, ensure full, fair, accurate, timely, and understandable public disclosures in periodic reports required to be filed by the Company, require compliance with applicable laws, rules and regulations, and encourage prompt internal reporting of violations of the Code of Business Conduct and Ethics. All officers and employees are required to annually certify that they have read and agree to abide by the terms of the Code of Business Conduct and Ethics. Additionally, the Code of Business Conduct and Ethics is in conformity with the requirements of the Sarbanes-Oxley Act of 2002 and the NASDAQ rules. A copy of the Code of Business Conduct and Ethics and any amendments to or waivers of the requirements therein are available on the Company's website at www.enterprisebanking.com.

Board Attendance at Annual Meetings

Directors are required to attend the Company's annual meeting of stockholders. Absences will be allowed for serious personal or business obligations that cannot be rescheduled. All of the Directors who were serving in 2017 attended the 2017 annual meeting.

DIRECTOR COMPENSATION

All members of the Board of Directors are Directors of the Company and of the Bank. In 2017, non-employee Directors were paid $750 for attendance at each of the Board of Directors meetings, excluding the Board’s annual strategic meeting, for which they were paid $1,000. Non-employee Directors also receive fees for attendance at committee meetings as detailed in the following table:



Committee	2017 Committee Member Meeting Fee
Audit Committee	$700
Compensation and Corporate Governance/Nominating Committees	$600
Banking Technology Steering, Enterprise Wealth Management, Loan and Strategic Planning Committees	$500
Executive Committee (effective 4/18/17)	$600

In addition to these per meeting fees, in 2017, non-employee Directors were also paid annual retainers for their membership on the Board of Directors and for their additional services in various Board-related and other corporate capacities as detailed in the following table:



	Annual Retainer
Board of Directors	$26,419 (1)
Lead Director	$8,000
Audit Committee Chairperson	$7,500
Compensation Committee Chairperson	$6,000
Corporate Governance/ Nominating Committee Chairperson	$6,000
Corporate Governance/ Nominating Committee Vice-Chairperson (currently no Vice-Chairperson)	$3,000
Banking Technology Steering Committee Chairperson	$6,000
Enterprise Wealth Management Committee Chairperson	$6,000
Enterprise Wealth Management Committee Vice-Chairperson	$3,000
Loan Committee Chairperson (2)	$6,000
Loan Committee Vice-Chairperson	$3,000
Loan Committee members	$2,400
Strategic Planning Committee Chairperson	$6,000
Secretary	$500

Cash retainers for membership on the Board of Directors and the Loan Committee were paid in equal monthly installments for each member. All other cash retainers were paid in equal quarterly installments.


(1)	This amount reflects the annual cash retainer and awards of 6,944 shares of restricted stock with a grant date value of $13,219 per non-employee Director. The shares of restricted stock generally vest over a two-year period.


(2)	This retainer is paid only when the Loan Committee Chairperson is a non-employee Director.

Directors who are also full-time salaried officers of the Bank were not paid for attending Board of Directors or committee meetings in 2017 and did not receive retainers of any kind for their services in any capacity as Directors.

For the year 2017, non-employee Directors had the option to make an irrevocable election (by December 31, 2016) to receive shares of Common Stock in lieu of receiving all or a portion of cash fees. The number of shares issued to non-employee Directors pursuant to this election was based on the closing price of the Common Stock on the NASDAQ Global Market on January 3, 2017. For the year 2017, the Company issued a total of 7,326 shares of Common Stock to eight non-employee Directors at a per share issuance price of $38.39. These shares were issued in January 2018. For the year 2018, non-employee Directors have the same option to receive shares of Common Stock in lieu of cash fees at a per share issuance price of $33.50, which reflects the value of the Common Stock on January 2, 2018, based on the closing price of the Common Stock on the NASDAQ Global Market on that date.

The Company believes that giving non-employee Directors the option to receive stock in lieu of cash fees and granting to them restricted stock awards with time-vesting requirements further aligns such Directors’ interests with those of the Company’s stockholders.

The following table details the total compensation paid to each non-employee Director for the year ended December 31, 2017.

COMPENSATION DISCUSSION AND ANALYSIS

Overview

This section details the Company’s executive compensation philosophy and contains a discussion of each material element of the Company’s executive officer compensation program as it relates to the following “named executive officers” (the “Named Executive Officers”) whose compensation information is detailed below:

George L. Duncan Executive Chairman

John P. Clancy, Jr. Chief Executive Officer

Richard W. Main President

James A. Marcotte Chief Financial Officer and Treasurer

Stephen J. Irish Managing Director of Wealth Management and Chief Operating Officer

Executive Compensation Philosophy and Objectives

The Company’s executive compensation program is designed to attract, motivate, and retain highly qualified executive officers, who are vital to achieving the financial goals set by the Board of Directors and enhancing long-term value for stockholders, while operating the Company in a safe and sound manner. The Company’s executive compensation philosophy provides that total annual compensation levels should:

(1) reflect compensation levels of those found in other banking organizations of comparable asset size, performance and geography;

(2) reflect individual responsibilities, contribution, leadership, experience, skill set and performance; and

(3) provide incentive to achieve business and financial objectives within reasonable risk parameters.

The Company at least annually assesses total compensation paid to its executive officers. As part of this process, the Compensation Committee assesses and evaluates the elements of total compensation listed below under the 2017 Executive Compensation Program paid to executive officers, including the Named Executive Officers, as a group and individually.

Compensation Committee and Independent Consultant Roles

Consistent with our philosophy, the Compensation Committee regularly obtains information regarding compensation levels in the Company’s industry through various sources, including compensation surveys conducted by banking industry associations and independent compensation consultants. The Compensation Committee also reviews the responsibilities and performance of the Company’s executive officers. Elements of compensation are

established with the goal of incentivizing and rewarding the executive officers for individual performance and organizational short- and long-term goals without encouraging excessive risk-taking.

Under the Compensation Committee Charter, the Compensation Committee follows the process outlined under the “Role of the Compensation Committee” as described further under Compensation Committee Matters on page 28 below.

The Compensation Committee annually engages a compensation consulting firm to review the elements of the Company’s executive compensation and to provide comparative market information on total executive compensation including base salary, incentive cash compensation, and incentive equity compensation for the Compensation Committee’s review. The Compensation Committee engaged McLagan Partners, Inc. (“McLagan”) to conduct a comparative market review of the Company’s executive compensation programs for 2017. In addition to survey data, a peer group was developed consisting of publicly traded banks within the Northeast region of the United States, excluding the New York City metro area, with similar asset size and performance results to the Company and with a loan portfolio substantially consisting of commercial loans. At the time the peer group was selected, the Company was positioned at approximately the median of the peer group in terms of total assets, with asset size of the peer group ranging from $1.2 billion to $5 billion. The information was not gathered to benchmark executive compensation to particular levels within the peer and survey group; rather, it was reviewed to assess the competitiveness of total executive compensation. For 2018, the Compensation Committee engaged Pearl Meyer & Partners, LLC (“Pearl Meyer”) to assess executive compensation programs.

Working with McLagan, the Compensation Committee selected the following peer group:



OceanFirst Financial Corp.	Hingham Institute for Savings
Meridian Bancorp, Inc.	Western New England Bancorp, Inc.
Century Bancorp, Inc.	Lake Sunapee Bank Group
Univest Corp. of Pennsylvania	Citizens & Northern Corp.
Washington Trust Bancorp, Inc.	First Connecticut Bancorp, Inc.
Bryn Mawr Bank Corp.	BSB Bancorp, Inc.
Peapack-Gladstone Financial	Bar Harbor Bankshares
Camden National Corporation	Chemung Financial Corporation
Financial Institutions, Inc.	Codorus Valley Bancorp, Inc.
First of Long Island Corp.	SI Financial Group, Inc.
Merchants Bancshares, Inc.	Penns Woods Bancorp, Inc.

Compensation Elements and Rationale

Executive compensation may include any or a combination of the following components in addition to an executive’s base salary: incentive cash compensation, incentive equity awards, supplemental retirement benefit, supplemental life insurance benefit, income protection following a termination of employment under various circumstances, including following a change in control of the Company, and automobiles and club memberships for business development purposes. Each of these components is reviewed, both separately and from a total compensation perspective, and approved by the Compensation Committee and the independent members of the Board of Directors on at least an annual basis. The Company believes that by using a combination of these elements it is best able to find an effective balance in motivating each executive to achieve long-term and short-term goals without taking unnecessary or excessive risks that could threaten the Company’s financial condition or prospects, thereby enhancing long-term stockholder value. In establishing the components of compensation for each individual executive officer, the Compensation Committee considers the performance and responsibilities of the individual, the executive’s designation or role within the Company, the cost to the Company of the various components of compensation to be

provided, the tax and accounting implications in designing the Company’s compensation programs, and the support received from stockholders in 2014 and 2017 “Say on Pay” advisory votes. The Compensation Committee did not change its approach in 2018 and applied rationale similar to that used in the prior year. The Compensation Committee will continue to consider the outcome of the Company’s “Say on Pay” vote when making future compensation decisions for the Named Executive Officers.

Based upon the comprehensive reviews and comparative assessments performed by McLagan and various other factors, including a review of each executive’s responsibilities, experience in his role, leadership, contributions, overall performance, and a review of the various components of compensation provided to the individual executive, the Compensation Committee determined that the 2017 base salaries for Messrs. Duncan, Main, and Clancy would remain unchanged and Messrs. Marcotte and Irish were increased from 2016 levels, in part, to maintain alignment with the competitive range of base salaries found in the peer group for their positions. The base salary increases for 2017 were as follows: Mr. Marcotte from $246,373 to $258,692 and Mr. Irish from $246,373 to $258,692 in March 2017. In May 2017, Mr. Irish’s base salary increased from $258,692 to $310,000 due to his advancement to Managing Director of Wealth Management in addition to his role as Chief Operating Officer. For 2017, Mr. Main’s base salary remained at $309,000, Mr. Duncan’s base salary remained at $412,000, and Mr. Clancy’s base salary remained at $489,250.

For 2018, the Compensation Committee reviewed the various components of the compensation provided to each executive, assessed each executive’s responsibilities, leadership, overall performance, and contributions, and reviewed the comparative assessment provided by Pearl Meyer. The Compensation Committee determined that the base salaries for Messrs. Duncan, Main and Clancy will remain unchanged for 2018. The Compensation Committee determined that the base salaries for Marcotte and Irish would increase from 2017 levels, in part, to maintain alignment with the competitive range of base salaries found in the peer group for their positions. The base salary increases effective March 2018 are as follows: Mr. Marcotte from $258,692 to $270,333 and Mr. Irish from $310,000 to $328,600.

Incentive Compensation (Cash)

The terms of incentive cash compensation for executive officers are established by the Compensation Committee, subject to approval by the independent members of the Board of Directors, on an annual basis. Certain senior officers, including the Named Executive Officers, are eligible for incentive cash compensation through the Company’s Variable Compensation Incentive Plan. Payments for executives under the Variable Compensation Incentive Plan for 2017 were determined by various weighted elements of the Company’s performance, including net income, deposit growth, loan growth, loan quality, and non-interest revenue. Additionally, to focus executives on managing salary and benefits expense, the Plan included a multiplier for executives that reduced or increased their overall payout based on performance compared to specific targets for this area. Target incentive payout percentages of an executive officer’s base compensation earned in the plan year were 45% for Messrs. Duncan and Main, 50% for Mr. Clancy, 32.5% for Mr. Marcotte and, due to Mr. Irish’s advancement to Managing Director of Wealth Management and Chief Operating Officer, his target incentive payout increased from 32.5% to 35% in May 2017.

In 2017, the Company reported two unbudgeted items that impacted the net income results of the Company. Due to the Tax Cuts and Jobs Act, the Company incurred a tax expense charge of $4.8 million in the fourth quarter

of 2017. The Company excluded this expense from net income for the purposes of the 2017 Variable Compensation Incentive Plan. Additionally, the Company made an adjustment of $922,000 to plan results for an unanticipated reduction in tax expense due to a new accounting standard in 2017 that impacted the tax treatment of equity compensation. Under the terms of the 2017 Variable Compensation Incentive Plan, the Compensation Committee and Board of Directors determined that these two items were extraordinary events and adjusted the actual 2017 net income plan results by approximately $3.9 million for purposes of the 2017 Variable Compensation Incentive Plan payments.

Performance factors and their relative weighting as well as the performance for each factor under the plan are shown in the table below.



Performance Factor	Weight	Threshold		Target				Stretch	Level for 2017	Weighted Results
Performance Factor	Weight	0.5	0.75	1	1.25	1.5	1.75	2	Level for 2017	Weighted Results

Result Payable to Target Prior to Multiplier: 1.325

The salaries and benefits expense met the range to multiply the plan results by 1.05, increasing the overall results payable to target to 1.39125. The actual salaries and benefits fixed expense at year end was $41.623 million. The annualized salaries and benefits expense multiplier for 2017 was 1.05 if the expense was less than $41.794 million, 1.0 if the expense was between $41.794 million and $42.494 million, and 0.95 if more than $42.494 million in expense.

In 2017, the Compensation Committee approved payouts under the 2017 Variable Compensation Incentive Plan for the Named Executive Officers. Messrs. Duncan and Main received an actual payout of 62.61%, which resulted in the following cash payments: $257,937.85 for Mr. Duncan and $193,453.34 for Mr. Main. Mr. Clancy received an actual payout of 69.56%, which resulted in a cash payment of $340,334.44. Mr. Marcotte received an actual payout of 45.22%, which resulted in a cash payment of $115,683.84. Mr. Irish received an actual payout of 48.69%, which resulted in a cash payment of $139,957.19.

On March 20, 2018, the Board approved the Company’s 2018 Variable Compensation Incentive Plan. The 2018 plan applies to all of the Named Executive Officers. The Board approved specific performance factors, performance targets and percentage payout amounts for 2018 for each of the Named Executive Officers. The target payout percentage for Messrs. Duncan, Main, Clancy, and Marcotte remained unchanged from 2017 levels and were as follows: Mr. Clancy at 50%; Messrs. Duncan and Main at 45%; Mr. Marcotte at 32.5% of their actual annual regular earnings. To further align with the Company’s financial results and to ensure total cash compensation is within a competitive range, Mr. Irish’s target payout percentage was increased to 37.5% for 2018. As in 2017, payments for participants under the 2018 Variable Compensation Incentive Plan will be determined by various elements of the Company’s performance, including net income, deposit growth, loan growth, loan quality, and non-interest revenue.

Long-Term (Equity) Incentive Compensation

The Company attempts to align the interests of its executives with the long-term interests of stockholders through the granting of equity-based compensation awards, which have been in the form of stock options and restricted stock. Equity awards are intended to (1) enhance management’s sense of ownership and commitment to the long-term success of the Company, (2) encourage and reward management performance that increases the long-term success and stockholder value of the Company, and (3) attract and retain the senior leadership and management talent

the Company needs to be successful. At this time, the Compensation Committee anticipates that restricted stock, as well as stock options, will continue to serve as the primary vehicles to be used to achieve these objectives.

In connection with its compensation program, the Compensation Committee evaluates the issuance of equity grants to employees on an annual basis. Historically, equity grants have been considered and made during the first quarter of each year. The total number of stock options or restricted stock granted to all employees is determined after considering various factors, including measures on stockholder dilution, such as overhang and run rate. The number of stock options or value of restricted stock awards granted to individual employees, including executives, is also based upon various factors, but is primarily based upon an employee’s level of responsibility and individual performance and contribution, and, with respect to the Named Executive Officers and other senior management, the desired mix of compensation. Stock options and restricted stock grants for employees other than executive officers are recommended by the Chief Executive Officer and the total grant is subject to the approval of the Compensation Committee and Board of Directors. In addition to the recommendation of the Chief Executive Officer and Compensation Committee approval, stock options and restricted stock awards granted to executive officers must also be approved by independent members of the Board of Directors. In all cases, the exercise price of the stock option and the value of the restricted stock is established based on the market price of the Company’s common stock on the date of the grant.

On March 21, 2017, the Named Executive Officers received the following equity grants under the Enterprise Bancorp’s 2009 Stock Incentive Plan: 2,157 stock options and 4,548 shares of restricted stock to Mr. Duncan; 2,088 stock options and 4,402 shares of restricted stock to Mr. Clancy; 1,150 stock options and 2,428 shares of restricted stock to Mr. Main; 729 stock options and 1,534 shares of restricted stock to Mr. Marcotte; and 729 stock options and 1,534 shares of restricted stock to Mr. Irish. The shares of restricted stock will vest based on the Company reaching the specific targets in earnings per share cumulative totals set forth below. Specific incremental targets were set to align executive management with stockholder interests by requiring earnings targets be met for awards to vest rather than incremental time based vesting. If such targets are not met by December 31, 2021, unvested shares will be forfeited. The stock options, all of which are non-qualified stock options, have an exercise price of $30.46 per share (the market price of the Company’s common stock on the date of grant) and will vest 50% at year two and 50% at year four. The equity grant vesting schedules are aligned with the Company’s long-term performance goals.

The number of options and shares of restricted stock granted to the Named Executive Officers for 2017 were considered to be within competitive ranges for executive management based on the compensation consultant reports, and the Compensation Committee believes such equity grants meet the Company’s objective of executive employee participation in the Company’s equity compensation program aligning the executives’ interests with those of the stockholders.

On March 20, 2018, the Company granted to employees a total of 14,755 nonqualified stock options, at an exercise price of $34.33 per share (which reflected the market price of the Company’s common stock on the date of the grant), and 37,225 shares of restricted stock. For the Named Executive Officers and certain other specific senior employees, restricted stock grants will vest based on the Company reaching specific targets in earnings per share cumulative totals. For all other employees, restricted stock grants will vest 25% per year. Stock option grants to both Named Executive Officers and other employees will vest 50% at year two and 50% at year four. The Compensation Committee believes the equity grant vesting schedules are aligned with the Company’s long term performance goals.

The amounts granted to the Named Executive Officers in 2018 were as follows: 2,040 options and 4,036 shares of restricted stock to Mr. Duncan; 1,976 options and 3,906 shares of restricted stock to Mr. Clancy; 1,089 options and 2,154 shares of restricted stock to Mr. Main; 688 options and 1,362 shares of restricted stock to Mr. Marcotte; and 688 options and 1,362 shares of restricted stock to Mr. Irish. The number of options and shares of restricted stock granted to the Named Executive Officers for 2018 were considered to be within competitive ranges for executive management based on the compensation consultant reports, and the Compensation Committee believes

such equity grants meet the Company’s objective of executive employee participation in the Company’s equity compensation program aligning the executives’ interests with those of the stockholders.

Supplemental Retirement Benefit and Supplemental Life Insurance Benefit

The Compensation Committee believes that providing a supplemental retirement benefit, which is implemented through salary continuation agreements, and supplemental life insurance benefits serve as long-term retention tools, as well as provide a reward component to the executive.

The Bank is party to salary continuation and supplemental life insurance agreements with each of Messrs. Duncan and Main. The terms of these salary continuation agreements, and the annual amounts payable to the executives thereunder, are described further at page 39 below. The annual expense incurred by the Company in maintaining this supplemental retirement benefit for each executive equals the annual increase of the present value of the accumulated benefit to be paid to the executive. This amount is included for each of the executives in the Summary Compensation Table at page 30 below under the heading “Change in Pension Value and Nonqualified Deferred Compensation Earnings.”

The supplemental life insurance benefits that are payable to Messrs. Duncan and Main are included in the amounts shown as payable in the event of death in the table at page 39 below and are specifically referenced in footnote 3 to the table.

In 2006 and 2015, the Company initiated a supplemental life insurance benefit plan for a number of its employees in management positions. Under these plans, the Company has provided supplemental life insurance benefits to the employees, subject to certain restrictions. Messrs. Clancy, Marcotte and Irish participate in both the 2006 and 2015 plans. The amounts of their supplemental life insurance benefits are included in the amounts shown as payable in the event of death in the table at page 39 below and are specifically referenced in footnote 3 to the table.

Income Protection and Non-Compete

In addition to the above noted elements of compensation, Messrs. Duncan, Main and Clancy have employment agreements with the Company, which include non-competition restrictions, and Mr. Irish and Mr. Marcotte have change in control/non-competition agreements with the Company. These agreements provide the executive with income protection in the event of a termination of his employment under certain circumstances, including following a change in control of the Company. The Compensation Committee believes these agreements are an important tool in retaining key executives while providing protection to the Company by restricting the executive’s ability to compete in the Company’s marketplace if he were to leave prior to or as a result of any change in control. The Compensation Committee believes that the non-competition protection afforded by these agreements is beneficial in the Company’s competitive marketplace and that the payment amounts and related conditions thereto contained in the agreements are consistent with reasonable industry standards. The maximum amounts that may be paid to any executive under any of these agreements are limited by automatic “cutback” provisions that ensure payments will not exceed the limits specified under Section 280G of the Internal Revenue Code. The terms of these agreements are described at pages 36-38 below and the amounts payable thereunder to the executives under various termination scenarios are included in the table at page 39 below.

Perquisites

In addition to their participation in the Company’s general employee benefit plans, as described in footnote 5 of the Summary Compensation Table at page 30 below, the Company provides company-owned vehicles for the use of Messrs. Duncan, Main and Clancy. The Company also pays dues related to club memberships for business development purposes for Messrs. Duncan, Main, and Clancy. The Compensation Committee believes that the cost

of these additional perquisites is modest for the size of the Company and that providing them is consistent with maintaining a competitive total compensation and benefits package for senior management and for business development purposes.

Policies & Practices

Executive Officers and Directors Stock Ownership Guidelines

The Company has established stock ownership guidelines for its executive officers and Directors. The Company believes that the executive officer and Director stock ownership guidelines further strengthen the individual’s commitment to the Company’s future and further aligns their interests with those of the Company’s stockholders. The executive officers and Directors are required to meet the specific stock ownership guidelines as listed below. The individual will be required to meet the stock ownership guideline within five years of being hired or promoted to an executive officer or elected as a Director or from the implementation date of the guidelines. As of December 31, 2017, all executive officers and Directors met or exceeded the ownership guidelines.



Position	Stock Ownership Guideline
Executive Chairman and Chief Executive Officer	Three times base salary at date of calculation
President	Two times base salary at date of calculation
Executive Officer	One time base salary at date of calculation
Director	Five times total Board of Director cash and equity retainer

Ownership is calculated on the last business day of the calendar year using the closing price or book value of the Company’s common stock, whichever is greater and includes: shares owned outright individually or as a co-owner with a spouse, including those in the 401(k) self-directed brokerage account or Employee Stock Purchase Plan; shares owned but held in trust or in the name of an immediate family member; unvested restricted shares; and 60% of the difference between the market price and the exercise price of the employee’s vested stock options under Enterprise Bancorp’s 2009 and 2016 Stock Incentive Plans.

Incentive Compensation Recovery

In order to further align management’s interests with the interests of stockholders and support good governance practices, all incentive compensation awards made to officers with a title of senior vice president or above include a clawback provision. If the Company’s reported financial or operating results are determined by the Company to be subject to material negative restatement due to material noncompliance with any financial reporting requirement under the securities laws, fraud, or misconduct (other than a restatement caused by a change in applicable accounting rules or interpretations), the Company may require recoupment of full or partial payouts made under the short- and long-term compensation plans to participants with an officer status of Senior Vice President or above.

Anti-Hedging Policy

The Board has adopted, as part of the Company’s Insider Trading Policy, a policy prohibiting Directors, executive officers and employees from engaging in hedging activities involving the Company’s common stock by making an investment to reduce the risk of adverse price movements in the Company’s common stock.

COMPENSATION COMMITTEE MATTERS

Role of the Compensation Committee

The Compensation Committee of the Board of Directors is comprised of five members, all of whom are currently deemed to be independent. In determining the independence of the members, the Board of Directors has used the definition of (i) independence contained in Rule 5605(d)(2)(A) of the Marketplace Rules of the NASDAQ Stock Market, and (ii) “non-employee directors” within the meaning of Exchange Act Rule 16b-3, and has applied this definition consistently to all members of the Compensation Committee. The responsibility of the Compensation Committee is to review the performance of the Executive Chairman and recommend his compensation to the independent members of the Board of Directors for review and approval. The Executive Chairman and Compensation Committee review the performance of the Chief Executive Officer and President and recommend their compensation to the independent members of the Board of Directors for review and approval. The Company’s Chief Executive Officer evaluates the performance of the remaining executive officers and recommends their compensation to the Compensation Committee. The Compensation Committee reviews the Chief Executive Officer’s recommendations and submits its recommendation to the independent members of the Board of Directors for approval. During 2017, the independent members of the Board of Directors approved all recommendations presented by the Compensation Committee.

The Compensation Committee has the authority to retain or obtain advice from independent advisors, such as outside legal counsel and consulting firms, as it deems necessary to perform its role. After taking into consideration the factors set forth in NASDAQ Marketplace Rule 5605(d)(3)(D), the Compensation Committee obtained the services of McLagan, an Aon Hewitt Company in 2017 to provide market assessment information to the Compensation Committee, which is discussed in further detail in the Company’s Compensation Discussion and Analysis at pages 21-27 above. McLagan was paid $26,635 for these services in 2017. The Compensation Committee reviewed all factors, as provided by Management, for any potential or actual conflicts of interest with McLagan and the Board of Directors or the Company and determined there were no potential or actual conflicts with the Board of Directors or the Company.

The Compensation Committee operates under a written charter, a copy of which can be found on the Company’s website (www.enterprisebanking.com). The Compensation Committee annually reviews its charter and recommends any changes to the full Board of Directors. The charter requires the Compensation Committee to meet at least four times every year. In 2017, the Compensation Committee met six times.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Company’s Compensation Discussion and Analysis contained at pages 21-27 above (the “CD&A”) with management and based on this review and discussion the Compensation Committee has recommended to the Board of Directors that the CD&A be included in this Proxy Statement.

Risk Assessment of Compensation Policies and Practices

The Company has implemented an annual risk assessment of its compensation policies and practices, which is intended to determine whether any of its existing compensation policies or practices create incentives for taking unnecessary or excessive risks that are reasonably likely to have a material adverse effect on the Company. On the basis of its 2017 annual assessment, the Compensation Committee has determined that no changes to the Company’s existing compensation policies and practices are necessary at this time.

(1)	The 2017 salary includes 26 pay periods versus 26 pay periods in 2016 and 27 pay periods in 2015.


(2)	The value of the stock awards is based on the fair market value of the Common Stock on the date of grant. The fair market value was calculated as the closing price of the Common Stock on the NASDAQ Global Market on the date of grant, March 21, 2017, which equaled $30.46 per share.

(3)

The value of the option awards is based on the fair market value of the awards as calculated using the Black-Scholes option valuation model. For assumptions used in calculating the value of option awards and the accounting treatment of the awards, refer to footnote 12 at page 120 of the Company’s Annual Report on Form 10-K, which is incorporated herein by reference. For information on vesting, refer to the table “Outstanding Equity Awards at Fiscal Year-End” and the associated footnote 1 at page 34-36 below.

(4)

For each of Messrs. Duncan and Main this amount is equal to the increase in 2017, 2016 and 2015 of the present value of the accumulated benefit attributable to the executive’s supplemental retirement plan, excluding the impact of the decrease in the liability from the change in discount rate in 2015. The amounts shown in 2017, 2016 and 2015 take into account payments received by Mr. Duncan and Mr. Main through their supplemental retirement plan in each of those years. In 2017, the discount rate used to determine the present value of the accumulated benefit was updated to 4.50% from 4.75% resulting in the value to the employee increasing $18,081 and $14,703 for Messrs. Duncan and Main, respectively. In 2016, the discount rate used to determine the present value of the accumulated benefit was unchanged from 2015 at 4.75%. In 2015, the discount rate used to determine the present value of the accumulated benefit was updated to 4.75% from 4.50% resulting in the value to the employee decreasing $23,592 and $18,414 for Messrs. Duncan and Main, respectively. There were no changes to the terms or amounts of the benefit paid to the employees based on the discount rate change.

Pay Ratio Disclosure for Enterprise Bancorp, Inc.

As required by Item 402(u) of Regulation S-K, we are providing the following information:

For fiscal 2017, our last completed fiscal year:


•	The median of the annual total compensation of all employees of our company (other than Mr. Clancy), was $59,548; and


•	The annual total compensation of Mr. Clancy, our Chief Executive Officer, was $1,024,380.

Based on this information, the ratio for 2017 of the annual total compensation of our Chief Executive Officer to the median of the annual total compensation of all employees is 17 to 1.

We completed the following steps to identify the median of the annual total compensation of all our employees and to determine the annual total compensation of our median employee and CEO:


1.	As of October 2, 2017, our employee population consisted of approximately 495 individuals, including any full-time, part-time, temporary, or seasonal employees employed on that date.

To find the median of the annual total compensation of all our employees (other than our CEO), we used wages from our payroll records as reported to the Internal Revenue Service on Form W-2 for fiscal 2017. In making this determination, we annualized the compensation of full-time and part-time permanent employees who were employed on October 2, 2017, but did not work for us the entire year. No full-time equivalent adjustments were made for part time employees.


3.	We identified our median employee using this compensation measure and methodology, which was consistently applied to all our employees included in the calculation.


4.	After identifying the median employee, we added together all of the elements of such employee’s compensation for 2017 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $59,548.


5.	With respect to the annual total compensation of our CEO, we used the amount reported in the “Total” column of our 2017 Summary Compensation Table.

(3)	The market value of the shares subject to restricted stock awards that have not vested is based upon the value of the Common Stock on December 29, 2017, the last business day of the Company’s last completed fiscal year. The closing market price of the stock on the NASDAQ Global Market on December 29, 2017 was $34.05.

AGREEMENTS WITH NAMED EXECUTIVE OFFICERS

The Company and the Bank are parties to employment agreements with Messrs. Duncan, Main and Clancy and change in control/noncompetition agreements with Messrs. Irish and Marcotte. The Bank is also a party to salary continuation agreements with Messrs. Duncan and Main and supplemental life insurance agreements with Messrs. Duncan, Main, Clancy, Irish and Marcotte.

Each of the employment agreements with Messrs. Duncan, Main and Clancy is for a fixed term of three years, subject to an automatic “rolling” renewal each year, unless either the Company or the executive provides a notice of non-renewal, in which case the agreement will expire at the end of the then-current term. Each of Messrs. Duncan, Main and Clancy is guaranteed a minimum base salary under the terms of his employment agreement: $400,000 for Mr. Duncan; $300,000 for Mr. Main; and $475,000 for Mr. Clancy. At least annually, these amounts are reviewed for increases by the Board. Additionally, Messrs. Duncan, Main, and Clancy are guaranteed minimum target total direct compensation, including base salary, target incentive bonus opportunity, and equity grant value: $720,000 for Mr. Duncan, $505,000 for Mr. Main, and $845,000 for Mr. Clancy. Actual total direct compensation will vary based on the Bank’s performance.

The amount of severance payments and benefits, if any, which may be due to any of the Named Executive Officers under any of the agreements referenced above following any form of termination of the executive is summarized generally below and is further quantified in the table at page 39 of this Proxy Statement.

Under the employment agreements with Messrs. Duncan, Main and Clancy, if the executive dies or for Messrs. Duncan and Main is terminated at any time as a result of his long-term disability (as defined in the agreement), the executive or his beneficiary will be paid a lump sum equal to his highest annual compensation (as defined in the agreement to include the sum of the executive’s highest annual base salary and highest annual cash bonus paid at any time prior to the date of termination since January 1, 2004). Upon termination for disability, Messrs. Duncan, Main, and Clancy and each of their spouses and any other eligible dependents will continue to receive health and welfare benefits at no cost, subject to limitations described in the agreement for a period of 18 months or upon the executive’s death, his spouse and any other eligible dependents will continue to receive health and welfare benefits at no cost, subject to limitations described in the agreement; provided, however, that if the executive dies or is terminated as a result of a long-term disability either within three years before or two years after the occurrence of a change in control of the Company (as defined in the agreement), then, in addition to such continuing health and welfare benefits, the executive or executive’s beneficiary will be paid a lump sum equal to three times the executive’s previous highest annual compensation (as defined in the agreement) (such

lump sum payment being referred to herein as the “Lump Sum Payment”), subject to reduction for any prior lump sum payment that may have been paid following the termination for death or long-term disability of the executive.

In addition to the foregoing death benefits payable to Messrs. Duncan, Main and Clancy under their employment agreements, the beneficiaries of each of the Named Executive Officers will also be paid the death benefits provided under the executive’s supplemental life insurance agreement, the amounts of which are included in footnote 3 to the table at page 39 below.

Under the employment agreements with Messrs. Duncan, Main and Clancy, if the executive chooses to terminate his employment at any time without good reason, including on or after a specified retirement age (62 for Mr. Clancy and Mr. Main has met the specified age of 63), he will be entitled to receive any bonus actually awarded or earned for a prior or current year, but not yet paid as of date of termination and continuing health and welfare benefits for 18 months on the same terms as were available to him as an employee, subject to limitations as described in the agreement, unless the executive chooses to terminate his employment without good reason either within three years before or one year after the occurrence of a change in control, in which case the executive will be paid the Lump Sum Payment.

In addition to the rights provided to Messrs. Duncan and Main under their employment agreements, the salary continuation agreements referenced above also provide additional annual compensation benefits payable to Messrs. Duncan and Main, subject to acceleration upon a change in control (as defined in the agreement), and became payable to the executive for a 20-year period upon his reaching a specified age (68 for Mr. Duncan, which he reached on June 8, 2008, and 63 for Mr. Main, which he reached on April 3, 2010), whether or not the executive retired or remained employed with the Company. The annual amounts payable to each of Messrs. Duncan and Main under their salary continuation agreements are $149,500 and $95,300, respectively.

Under the employment agreements with Messrs. Duncan, Main and Clancy, if the Company (including any successor) terminates the executive at any time for cause, whether before or after the occurrence of a change in control, the executive will be entitled to receive any accrued but unpaid compensation and benefits and will not be entitled to receive any severance payments or benefits. However, if the Company (including any successor) terminates the executive at any time without cause, whether before or after the occurrence of a change in control, then the executive will be paid the Lump Sum Payment, be reimbursed for professional outplacement service, and will be entitled to receive continuing health benefits for 18 months at no cost to the executive, subject to limitations as described in the agreement.

Under the employment agreements with Messrs. Duncan, Main and Clancy, if the executive chooses to terminate his employment at any time for good reason (as defined in the agreement to include, among several other reasons, a 10% reduction in the executive’s base salary, annual target incentive, or annual equity grant value or material diminution in his authority, duties or responsibilities), whether before or after the occurrence of a change in control, then the executive will be paid the Lump Sum Payment, be reimbursed for professional outplacement service, and will be entitled to receive continuing health benefits for 18 months at no cost to the executive, subject to limitations as described in the agreement.

Each of the employment agreements with Messrs. Duncan, Main and Clancy also provides that the parties may agree to a flexible work arrangement for the remaining term of the agreement. Under the terms of such arrangement, if executive reduces his work schedule below 80% of full-time status, the parties may agree to modify the executive’s position, time and effort, and compensation and the Bank will continue to provide the executive with full benefits, subject to the limitations described in the agreement or equivalent cash compensation taking into account state and federal income taxes.

Under each of the employment agreements with Messrs. Duncan, Main and Clancy, the executive is subject to confidentiality, non-compete and non-solicitation restrictions for up to one year after the termination of his employment for any reason if the termination occurs before a change in control. The non-compete restrictions

do not apply following any termination of the executive’s employment that occurs after a change in control, and any non-compete restrictions that may be in effect at the time of a change in control automatically expire upon such change in control. If the executive breaches any applicable confidentiality, non-compete or non-solicitation covenants, then the Company may enforce a right to recoup prior severance payments made to the executive.

Under the terms of the change in control/noncompetition agreement with Messrs. Irish and Marcotte, the executive will be paid a lump sum equal to 1.5 times his previous highest annual compensation (as defined in the agreement to include the sum of the executive’s highest annual base salary and highest annual cash bonus paid within the most recent three years prior to the date of termination), together with certain other specified payments and benefits, including continuation of health and welfare benefits for 18 months on the same terms as were available to the executive as of the date of termination or, if more favorable, as of the date of the change in control, if the executive’s employment is terminated for any reason, whether at the initiative of the Company or of the executive and whether or not for cause, within two years after the date of a change in control of the Company. If Mr. Irish’s or Mr. Marcotte’s employment is terminated for any reason within one year prior to the occurrence of a change in control, other than for cause, then he is entitled to receive all of the payments and benefits that he would have been entitled to receive if such termination had occurred within two years after the date of such change in control.

Messrs. Irish and Marcotte are also subject to confidentiality, non-compete and non-solicitation restrictions for one year following a termination of employment for any reason prior to a change in control (and assuming a change in control does not occur within this one-year period). If Mr. Irish’s or Mr. Marcotte’s termination in the absence of any change in control is initiated by the Company for any reason other than for cause, then he will be paid a lump sum equal to 75% of the sum of his then-current annual base salary and the amount of any annual incentive or other bonus paid to him with respect to the most recently completed fiscal year prior to the date of termination, subject to recoupment by the Company if he breaches any of the applicable confidentiality, non-compete and non-solicitation covenants.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE OF CONTROL

The following table summarizes the estimated payments and benefits to be provided to the Named Executive Officers, as of December 31, 2017, under the various termination scenarios referenced in the table for each of the Named Executive Officers. The estimates shown below factor in base salary and incentive compensation payments, the value realized from accelerated vesting of stock options and restricted stock, the value realized from accelerated vesting of supplemental retirement benefits and other benefits and payments to be paid to the Named Executive Officers under the terms of any agreement or plan that is not generally available to all employees. The following calculations were made without giving consideration to any possible “cutback” or other reduction of payments or benefits that could be required under an executive’s employment or other contract:



Name	Change in Control (1)		Voluntary Termination (Includes Early Retirement) (2)		Involuntary Not for Cause Termination by Company or, if Applicable, Good Reason Termination by Employee		For Cause Termination		Normal Retirement (2)		Death (2)(3)		Disability
George L. Duncan (4)	$	2,549,270	$	277,283	$	2,027,095	$	257,938	$	277,283	$	2,660,472	$	1,123,761

(1)

With respect to each of Messrs. Duncan, Clancy, Main, Irish and Marcotte the amount shown includes the amount payable, including the estimated expense of continuing benefits, under various termination scenarios either preceding or following a change in control under the executive's employment agreement or, in the case of Messrs. Irish and Marcotte, their change in control/noncompetition agreement, which are described in further detail under the heading “Agreements With Named Executive Officers" at pages 36-38 above.

The amounts shown also include the present value attributable to accelerated vesting of death benefit payable under the Bank’s executive supplemental life insurance plan, which is $75,421 for Mr. Clancy, $66,762 for Mr. Irish and $67,652 for Mr. Marcotte, and the value attributable to the accelerated vesting of outstanding stock options and unvested restricted stock, which is $520,111 for Mr. Duncan, $515,583 for Mr. Clancy, $282,096 for Mr. Main, $176,326 for Mr. Irish and $176,326 for Mr. Marcotte. The value of any outstanding stock options and unvested restricted stock is based upon the value of the Common Stock on December 29, 2017, which was $34.05 per share, the closing market price of the stock on the NASDAQ Global Market on that date.


(2)	With respect to each of Messrs. Duncan, Clancy, Main, Irish and Marcotte assumes that termination has not occurred within the time periods before or after a change in control specified in his employment agreement or change in control/noncompetition agreement as applicable.


(3)	Includes amounts payable under supplemental life insurance benefits, which equal the following amounts for each of the executives: $1,556,056 for Mr. Duncan; $286,726 for Mr. Clancy; $791,496 for Mr. Main; $278,689 for Mr. Irish; and $268,623 for Mr. Marcotte.

(4)

In addition to the amounts payable to Messrs. Duncan and Main under the various scenarios shown in the table above, each of the executives has a fully vested right to receive annual amounts payable over a 20 year period under the executive’s salary continuation agreement. These annual amounts, payable in monthly installments, are paid to the executive regardless of his employment status, unless the executive is terminated for cause, in which case he would forfeit his right to receive any further payments following the date of termination. In 2017, both Messrs. Duncan and Main were eligible to receive payments under their salary continuation agreements, and each received the full annual amount to which he is entitled, detailed in the table below.

PENSION BENEFITS

The following table sets forth additional information concerning the supplemental retirement benefits as of December 31, 2017:



Name	Plan Name	Number of Years of Credited Service (#)	Present Value of Accumulated Benefit ($) (1)		Payments During Last Fiscal Year ($)
George L. Duncan	Supplemental Employee Retirement Plan	29	$	1,229,590	$	149,500
Richard W. Main	Supplemental Employee Retirement Plan	29	$	888,715	$	95,300


(1)	The present value of accumulated benefit was valued at the established present value of the payments to be received by the executives upon reaching the specified ages noted above at a discount rate of 4.50%. The annual benefit will be payable in twelve monthly installments.

DIRECTOR NOMINATIONS AND STOCKHOLDER COMMUNICATIONS

Proposed director nominees are recommended to the Board of Directors for its approval by the Company’s Corporate Governance/Nominating Committee.

The Corporate Governance/Nominating Committee’s Charter and the Company's Corporate Governance Guidelines outline director qualifications, appointment to and removal from the Board of Directors and its various committees, structure and operations of the Board of Directors and its various committees and its reporting function to the Board of Directors. A copy of the Corporate Governance/Nominating Committee’s Charter and the Company's Corporate Governance Guidelines can be found on the Company's website (www.enterprisebanking.com/investor-relations.html).

In evaluating candidates, the Committee considers independence, experience relevant to the needs of the Company, leadership qualities and the ability to represent the broad interests of stockholders. In selecting new Directors, consideration is given to both the personal qualities and abilities of individual candidates and the existing collective skills and aptitudes of the Board of Directors as a whole.

Although it does not have a formal diversity policy, in addition to the criteria described above, the Board and the Corporate Governance/Nominating Committee also consider professional, personal and geographic diversity in their review of candidates. Overall, candidates are selected based on a review of qualifications that are considered in the best interest of the stockholders.

Nominees for election to the Board of Directors may be identified and submitted to the Committee for its consideration by Directors, stockholders and/or management. The Committee may also retain a professional search firm to assist with the identification of qualified candidates.

Stockholders may submit nominations for candidates for election to the Board of Directors in accordance with the applicable requirements contained in the Company’s By-Laws to the attention of the Company's Secretary at the Company’s principal office located at 222 Merrimack Street, Lowell, Massachusetts 01852.

Stockholders may also communicate directly with members of the Board of Directors by sending such communications to a specified director or group of Directors or to the Board of Directors in its entirety, addressed c/o the Secretary of the Company at the Company's principal office at the foregoing address.

AUDIT COMMITTEE REPORT

The Audit Committee of the Company's Board of Directors (the “Audit Committee”) is comprised of six independent Directors and operates under a written charter. The Audit Committee reviews and reassesses the adequacy of the Audit Committee charter on an annual basis. The Board of Directors has determined that Carol Reid, who is one of these six independent Directors, qualifies to serve as an Audit Committee Financial Expert (as such term is defined under applicable SEC rules). The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of the work of the Company’s independent registered public accounting firm, which reports directly to the Audit Committee. The Audit Committee evaluates the Company’s independent registered public accounting firm and the lead audit engagement partner, at a minimum, on an annual basis with consideration given to past performance, the quality of communications with the Audit Committee and management, professional qualifications, expertise and reputation of the firm, and continued independence.

Management is responsible for the Company’s internal controls, the financial reporting process and compliance by the Company with legal and regulatory requirements. The Company’s independent registered public accounting firm is responsible for performing an independent audit of the Company's consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) and for auditing whether the Company maintained, in all material respects, effective internal controls over financial reporting and for issuing reports thereon. The Audit Committee’s responsibility is to monitor and oversee these processes. The Audit Committee’s responsibilities also include resolving any disagreements that may arise between management and the Company's independent registered public accounting firm. In addition, the Audit Committee is responsible for the oversight of financial reporting, oversight of the Company’s Internal Audit function, oversight of management’s efforts to manage third party risk, the oversight of compliance by the Company with legal and regulatory requirements, and oversight of procedures established for the receipt, retention and treatment of any complaints that may be received by the Company regarding accounting, internal controls or auditing matters and the confidential, anonymous submission by employees of the Company of any concerns that may arise regarding questionable accounting or auditing matters.

The Audit Committee has met and held discussions with management and the Company’s independent registered public accounting firm. Management has represented to the Audit Committee that the Company’s consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles, and the Audit Committee has reviewed and discussed the consolidated financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has discussed with the Company’s independent registered public accounting firm the matters required to be discussed under the professional standards of the AICPA and Public Company Accounting Oversight Board.

The Company’s independent registered public accounting firm has also provided to the Audit Committee the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and the Audit Committee has discussed with the Company’s independent registered public accounting firm that firm’s independence.

Based upon the Audit Committee’s discussions with management and the Company’s independent registered public accounting firm, and the Audit Committee’s review of the representation of management and the reports of the Company’s independent registered public accounting firm to the Audit Committee, the Audit

Committee recommended that the Board of Directors include the audited consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017 as filed with the SEC.

The Committee and the Board of Directors have also recommended, subject to shareholder ratification, the selection of RSM LLP, as the Company’s independent registered public accounting firm for the year ending December 31, 2018.

TRANSACTIONS WITH CERTAIN RELATED PERSONS

Since January 1, 2017, neither the Company nor the Bank has been a party to any transaction or series of transactions in which the amount involved exceeded $120,000 and which any director, executive officer, or holder of more than 5% of our stock, or any member of the immediate family of any such person, had or will have a direct or indirect material interest other than standard compensation arrangements described in “Executive Compensation” and the transaction described below.

Director Kenneth Ansin previously served as Senior Vice President, Regional Community Banking Director for the Bank. During 2017, Mr. Ansin received total compensation, including regular base earnings, value of equity awards and certain benefit expenses that are provided to all employees, in the amount of $146,940 from the Bank.

Certain Directors and executive officers of the Company are also customers of the Bank and have entered into loan, wealth management and brokerage and deposit transactions with the Bank in the ordinary course of business. In addition, certain Directors are also directors, trustees, officers or stockholders of corporations and non-profit entities or members of partnerships that are customers of the Bank and that enter into loan and other transactions with the Bank in the ordinary course of business. Such loan transactions with Directors and executive officers of the Bank and with such corporations, non-profit entities and partnerships are on such terms, including interest rates, repayment terms and collateral, as those prevailing at the time for comparable transactions with persons who are not affiliated with the Bank and do not involve more than a normal risk of collectability or present other features unfavorable to the Bank. Charitable contributions have been made in the normal course of business to certain non-profit organizations where Directors serve as officers or directors of these organizations.

The Audit Committee reviews disclosures made in this Proxy Statement and all other reports and filings of the Company required under the federal securities laws regarding all related-party transactions that are required to be disclosed under the requirements of Item 404 of the SEC’s Regulation S-K. Any transactions involving the Company (including any subsidiaries) and related parties must be conducted on an arm's-length basis and any consideration paid or received by the Company in connection with any such transaction shall be on terms no less favorable to the Company than terms that would be available under the same or similar circumstances with an unaffiliated third party. With respect to any such transaction, the related party's interest is disclosed to the Corporate Governance/Nominating Committee prior to any action being taken.
