PROXY STATEMENT

These proxy materials are delivered by the Board of Directors of Enterprise Financial Services Corp (the “Company” or “EFSC”), in connection with the solicitation of proxies to be voted at the 2016 Annual Meeting of Stockholders or any adjournment or postponement thereof. The meeting will be held at the Ritz-Carlton Amphitheater, 100 Carondelet Plaza, St. Louis, Missouri 63105 on Thursday, May 5, 2016 at 5:00 p.m. local time.

This Proxy Statement and the proxy card were first provided to stockholders on or about March 16, 2016.

QUESTIONS ABOUT THE MEETING AND THESE PROXY MATERIALS

What may I vote on?

1. The election of 11 directors named in this Proxy Statement to hold office until the next Annual Meeting of Stockholders or until their successors are elected and have qualified.

2. Proposal A, ratification of the selection of Deloitte & Touche LLP as independent registered public accounting firm.

3. Proposal B, an advisory (non-binding) vote to approve our executive compensation, as disclosed in this proxy statement.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE FOR THE ELECTION AS DIRECTORS OF THE NOMINEES NAMED HEREIN, AND A VOTE IN FAVOR OF PROPOSAL B. THE AUDIT COMMITTEE UNANIMOUSLY RECOMMENDS A VOTE IN FAVOR OF PROPOSAL A.

Who can vote at the meeting? Our Board of Directors has set March 7, 2016 as the record date for the Annual Meeting. All stockholders who owned our common stock at the close of business on the record date may vote at the Annual Meeting. On the record date, there were 20,021,077 shares of common stock outstanding. Shares held as of the record date include shares that are held directly in your name as the stockholder of record and those shares held for you as a beneficial owner through a stockbroker, bank or other nominee.

How do I vote my shares? If your shares are registered directly in your name with our stock transfer agent, Computershare, you are considered a stockholder of record and the beneficial owner of those shares. As a stockholder of record, you have the right to grant your voting proxy directly to the Company, or to vote in person at the meeting. You may submit your proxy by mail, over the internet at www.proxyvote.com, or via the telephone at 1-800-690-6903.

If your shares are held in a stock brokerage account or by a bank, you are still considered the beneficial owner of those shares, but your shares are said to be held in “street name.” Generally, only stockholders of record may vote in person at the meeting. If your shares are held in street name, you will receive a form from your broker or bank seeking instruction as to how your shares should be voted. If you desire to vote shares held in street name in person at the meeting, you need to contact your broker and ask how to obtain a “legal proxy” to directly vote such shares.

Internet Availability of Proxy Solicitation and Other Annual Meeting Materials. Rules adopted by the U.S. Securities & Exchange Commission, or SEC, permit us to mail a notice to our stockholders advising that our proxy statement, annual report to stockholders, electronic proxy card and related materials are available for viewing, free of charge, on the Internet. Stockholders may then access these materials and vote over the Internet or request delivery of a full set of materials by mail or email. These rules help us lower the cost of conducting our annual meeting by reducing costs associated with printing and postage.

We will begin mailing the required Notice of Internet Availability of Proxy Materials to stockholders on or about March 16, 2016. The proxy materials will be posted on the Internet, at www.proxyvote.com, no later than the day we begin mailing the Notice. If

1

you receive the Notice, you will not receive a paper or email copy of the proxy materials unless you request one in the manner set forth in the Notice.

The Notice of Internet Availability of Proxy Materials contains the following important information:

• The date, time and location of the annual meeting;

• A brief description of the matters to be voted on at the meeting;

• A list of the proxy materials available for viewing on www.proxyvote.com and the control number you will use to access the site; and

• Instructions on how to access and review the proxy materials online, how to vote your shares over the Internet, and how to get a paper or email copy of the proxy materials, if that is your preference.

Can I change my vote? Yes. If you are the stockholder of record, you may revoke your proxy at any time before the Annual Meeting by:

• entering a new vote by Internet or telephone;

• returning a later-dated proxy card;

• sending written notice of revocation to the Secretary of the Company; or

• attending the Annual Meeting and voting by ballot.

To change your vote for shares you hold in street name, you will need to follow the instructions provided by your broker or bank.

How are shares of Common Stock voted at the meeting? Each holder of common stock is entitled to one vote for each share of common stock held with respect to each matter to be voted upon.

All shares of common stock represented at the Annual Meeting by properly executed proxies received prior to or at the Annual Meeting which are not properly revoked will be voted at the Annual Meeting in accordance with the instructions indicated on the proxies. If no contrary instructions are indicated, proxies will be voted FOR the election of the Board's director nominees and FOR approval of Proposals A and B.

How many votes are required to elect each director? A plurality of votes cast at the Annual Meeting is required for the election of each director, which effectively means that the 11 persons receiving the most votes will be elected as directors. While directors are elected by a plurality of votes cast, our Board has adopted a majority voting policy for directors. This policy states that in an uncontested election, any nominee who receives a greater number of votes "withheld" from his or her election than votes "for" such election is required to submit his or her resignation to the Board. The Nominating and Corporate Governance Committee of the Board is required to make recommendations to the Board with respect to any such tendered resignation. The Board will act on the tendered resignation within 90 days from the certification of the vote and will publicly disclose its decision, including its rationale. Only votes “for” or “withheld” are counted in determining whether a plurality has been cast in favor of a nominee. If you withhold authority to vote with respect to the election of some or all of the nominees, your shares will not be voted with respect to those nominees indicated. For a “withheld” vote, your shares will be counted for purposes of determining whether there is a quorum and will have a similar effect as a vote against that director nominee under our majority voting policy for directors.

How many votes are required to adopt the other proposals? Proposals A and B will be adopted if a majority of the votes cast on the respective proposal are in favor.

How do I vote if my shares are held in a benefit plan? If you are a current or former employee of the Company or one of its subsidiaries and you have any portion of your investment funds allocated to the EFSC Common Stock Fund in the EFSC Incentive Savings Plan ("Savings Plan"), you may instruct the Savings Plan’s trustees how to vote the shares of common stock allocated to your account under the Savings Plan. You will instruct the voting of your stock in the same manner as other stockholders, i.e., by submitting your voting instructions by telephone or through the Internet or by requesting a proxy card to sign and return. Please see the Notice of Internet Availability of Proxy Materials we sent to you or this proxy statement for specific instructions on how to provide voting instructions by any of these methods. Please note that your voting instructions for stock you hold in the Savings Plan must be returned by 11:59 p.m. Eastern Time on May 2, 2016.

What if I don’t give specific voting instructions or abstain?

If you indicate a choice on your proxy on a particular matter to be acted upon, the shares will be voted as indicated.

If you are a stockholder of record and you return a signed proxy card but do not indicate how you wish to vote, the shares will be voted in favor of the election as directors of the nominees described in this proxy statement, for the proposals A and B. If you do not return the proxy card, your shares will not be voted and will not be deemed present for the purpose of determining whether a quorum exists.

2

Under the rules of the New York Stock Exchange, which regulates stock brokers, Proposal A, the ratification of the selection of Deloitte & Touche LLP as the Company's independent registered public accounting firm, is considered a routine matter, and your brokerage firm or other nominee will be entitled to vote your shares in their discretion on this proposal even if you do not provide voting instructions to your broker or other nominee. However, the election of directors and Proposal B-the advisory (non-binding) vote to approve our executive compensation, are not considered routine matters, and brokers will not be permitted to vote on these matters if beneficial owners fail to provide voting instructions. The shares that cannot be voted by brokers on non-routine matters are commonly referred to as “broker non-votes.”

Abstentions and broker non-votes (assuming a quorum is present) will have no effect on the election of directors or on Proposals A and B.

Who pays for this proxy solicitation? The Company will pay the entire cost of preparing, assembling, printing, mailing and distributing these proxy materials. In addition to solicitation by mail, proxies may be solicited in person or by telephone or by other means by the Company’s directors, officers or employees, who will not receive any additional compensation for solicitation activities. The Company has engaged Broadridge Financial Solutions, Inc., for a fee to be determined, to assist in the distribution and tabulation of proxies. The Company will also reimburse brokerage firms and other nominees, custodians and fiduciaries for costs incurred by them in mailing proxy materials to the beneficial owners of common stock as of the record date.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTEFOREACH OF THE

INDIVIDUALS LISTED ABOVE FOR ELECTION AS DIRECTORS OF THE COMPANY.

BOARD AND COMMITTEE INFORMATION

The Board of Directors has determined that having an independent director serve as Chairman of the Board is in the best interest of stockholders at this time. The structure ensures a greater role for the independent directors in the oversight of the Company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of the Board.

The Board is actively involved in oversight of risks that could affect the Company. This oversight is conducted primarily through committees of the Board, as disclosed in the descriptions of each of the committees below and in the charters of each of the committees, but the full Board has retained responsibility for general oversight of risks. The Board satisfies this responsibility through reports by each committee chair regarding the committee’s considerations and actions, as well as through regular reports directly from officers responsible for oversight of particular risks within the Company.

All Committee members are appointed by the Board. In addition, the Board has established membership standards for each committee which requires that a certain number of committee members must be “independent directors,” as that term is defined in Rule 5605(a)(2) of the NASDAQ rules.

The Board met six times in 2015. All directors attended at least 75% of all meetings of the full Board and of those committees on which they served in 2015. The Company’s Board of Directors periodically held executive sessions of the members of the Board who met the then current standards of independence. Executive sessions of the Board were presided over by the Chairman. While there is no formal policy concerning director attendance at the annual meeting, all members of the Board are encouraged to attend if reasonably able to do so. All 11 of the then current members of the Board attended the 2015 annual meeting.

For Committee service, the Chairpersons received an additional retainer as follows: Audit Committee ($10,000), Compensation Committee ($8,000) and Nominating and Governance Committee ($6,000). Non-Chairperson committee members receive $1,000 per committee meeting attended. Chairman Murphy received only an annual fee of $75,000.

Directors also receive attendance fees and stipends for service on the Board of Directors of Enterprise Bank & Trust and representing the holding company board on other committees and on the Bank's advisory boards. In 2015, Mr. Arnold received cash fees of $18,000 and Mr. Eulich received cash fees of $12,200 for their services on the Bank's board of directors.

Directors select whether to receive their holding company board compensation in 100% common stock or 50% cash / 50% common stock. Shares issued are calculated using the fair value on the date of payment and are not subject to vesting requirements. The shares are issued under the stockholder approved Stock Plan for Non-Management Directors.

EXECUTIVE COMMITTEE

The Executive Committee is empowered to act on behalf of, and to exercise the powers of, the full Board of Directors in the management of the business and affairs of the Company when the full Board of Directors is not in session, except to the extent limited by applicable Delaware law.

All actions by the committee are reported at the next regular Board of Directors meeting. In addition, approved Executive Committee minutes are shared with all Directors. In 2015, the committee met six times.

The Committee consists of six members, including five non-employee directors who are “independent directors” as defined in the NASDAQ standards. For 2015, the independent members of the Executive Committee consisted of Directors Murphy (Committee Chairman), DeCola, Van Trease, Heeter, and Eulich. The non-independent member of the Committee was Director Benoist.

AUDIT COMMITTEE

The Audit Committee oversees the Company’s financial reporting process on behalf of the Board of Directors by reviewing all audit processes and fees, the financial information provided to the stockholders and the Company’s systems of internal financial controls. The Audit Committee has the authority and responsibility to select and evaluate and, where appropriate, replace the Company’s independent registered public accounting firm (the “independent auditors”).

The Audit Committee is responsible for oversight of Company risks relating to accounting matters, financial reporting, legal and regulatory compliance and the Company’s anonymous "whistleblower" reporting system. To satisfy these oversight responsibilities, the Committee separately meets regularly with the Company’s chief financial officer, its director of internal audit, Deloitte & Touche LLP and management. The Committee chair periodically meets between formal Committee meetings with the Company’s chief financial officer, its director of internal audit, and Deloitte & Touche LLP. The Committee also receives regular reports regarding issues such as the status and findings of audits being conducted by the internal and independent auditors, the status of material litigation, accounting changes that could affect the Company’s financial statements and proposed audit adjustments.

All members of the Audit Committee meet the NASDAQ independence standards. In 2015, the Audit Committee consisted of Directors Van Trease (Committee Chairperson), Arnold, Guest, Downey, and Havel. The Audit Committee met five times in 2015.

The Board of Directors has determined that Directors Guest, Havel, and Van Trease satisfy the requirements of an “ audit committee financial expert” as defined in Item 407(d)(5) of Regulation S-K and satisfy the definition of “financially sophisticated” under NASDAQ Rule 5605(c).

The Company’s Board has determined that none of the Directors on the Audit Committee have a relationship with the Company or the Bank that would interfere with the exercise of independent judgment in carrying out their responsibilities as director. None of them is, or have been for the past three years, an employee of the Company or the Bank, and none of their immediate family members is, or have for the past three years, been an executive officer of the Company or the Bank.

As noted in the Audit Committee’s charter, which is available in the investor relations section of the Company’s website at www.enterprisebank.com, the Company’s management is responsible for preparing the Company’s financial statements. The Company’s independent auditors are responsible for auditing the financial statements. The activities of the Audit Committee are in no way designed to supersede or alter those traditional responsibilities. The Audit Committee’s role does not provide any special assurances with regard to the Company’s financial statements, nor does it involve a professional evaluation of quality of audits performed by the independent auditors. The Audit Committee reassesses the adequacy of the charter on an annual basis.

The Audit Committee has considered whether the provision by Deloitte & Touche LLP of the services covered by the audit fees is compatible with maintaining Deloitte & Touche LLP’s independence and concluded that it is compatible. The Audit Committee is responsible for pre-approving all auditing services and permitted non-auditing services to be performed by the Company’s independent auditors. The Chairperson of the Audit Committee has authority to approve in advance all audit or non-audit services to be performed by the independent auditors, but must report any such approval to the full Audit Committee at the next regularly scheduled meeting.

The Report of the Audit Committee appears on page 35 of this Proxy Statement.

NOMINATING AND CORPORATE GOVERNANCE COMMITTEE

The Nominating and Corporate Governance Committee assists the Board in identifying and recommending qualified director nominees for election at the stockholders’ annual meeting. The charter for the Nominating and Corporate Governance Committee may be found in the investor relations section of the Company’s website at www.enterprisebank.com. The Committee also recommends membership on Board committees, reviews and assesses the Company's governance guidelines, policies and practices, and oversees an annual Board self-evaluation.

All members of the Committee meet the NASDAQ independence standards. Nominating and Corporate Governance Committee members for 2015 were Directors Heeter (Committee Chairperson), DeCola, Mullins, and Murphy. The Committee met four times in 2015.

The Nominating and Corporate Governance Committee may consider candidates for Board membership coming to its attention through current Board members, search firms, stockholders and other persons. The Nominating and Corporate Governance Committee identified Mr. Holmes and recommended him for election to the Board. Suggestions for nominees from stockholders are evaluated in the same manner as other nominees. Any stockholder nomination must be submitted in writing to the Secretary,

8

Enterprise Financial Services Corp, 150 North Meramec, Clayton, Missouri 63105 and should include the stockholder’s name, address and number of the Company’s shares owned by the stockholder along with the nominee’s name and qualifications in accordance with the procedures set forth in our bylaws, as described in Proposals of Stockholders on page 36. No stockholder has properly nominated anyone for election as a director at the Annual Meeting.

There is no fixed process for identifying and evaluating potential candidates to be nominees for directors, and there is no fixed set of qualifications that must be satisfied before a candidate will be considered. Rather, the Nominating and Corporate Governance Committee has the flexibility to consider such factors as it deems appropriate. These factors may include education, diversity, experience with business and other organizations comparable with EFSC, the interplay of the candidate’s experience with that of other members of the Board of Directors, and the extent to which the candidate would be a desirable addition to the Board of Directors and to any of the committees of the Board of Directors. The Nominating and Corporate Governance Committee will evaluate nominees for directors submitted by stockholders in the same manner in which it evaluates other director nominees.

Stockholders may communicate directly to the Board of Directors, including individual directors, by sending a letter to the Board at: Enterprise Financial Services Corp Board of Directors, 150 North Meramec, Clayton, Missouri 63105. All communications directed to the Board of Directors will be received and processed by the Secretary of the Company and will be transmitted to the Chairperson of the Nominating and Corporate Governance Committee without any editing or screening.

COMPENSATION COMMITTEE

The Compensation Committee consists of Directors DeCola (Committee Chairman), Eulich, Holmes, Mullins, and Murphy. The Compensation Committee met seven times in 2015. The Compensation Committee is comprised solely of non-employee directors, all of whom the Board has determined are independent pursuant to the NASDAQ rules. The responsibilities of the Committee are set forth in its charter, which is available in the investor relations section of the Company’s website at www.enterprisebank.com, and includes the responsibility for establishing, implementing and continually monitoring compliance with the Company’s compensation philosophy. Members of the Committee are outside directors within the meaning of Section 162(m) of the Internal Revenue Code of 1986. During fiscal year 2015, no Member was an executive officer of another entity on whose compensation committee or board of directors an executive officer of the Company served.

The Compensation Committee is responsible for risks relating to employment policies and the Company’s compensation and benefits systems. To assist it in satisfying these oversight responsibilities, the Committee has retained its own compensation consultant and meets regularly with management and with outside counsel to understand the financial, human resources and stockholder implications of compensation decisions being made.

The Compensation Committee Report appears on page 21 of this Proxy Statement.

RISK COMMITTEE

The Risk Committee assists the Board in carrying out its responsibilities with respect to the comprehensive oversight of the types and levels of risk being incurred by the organization, and the effectiveness of the methods used to identify, monitor, manage, and report those risks. The charter for the Risk Committee may be found at the Company's website at www.enterprisebank.com.

The responsibilities of the Risk Committee are to review the Company's Risk Appetite Statement and Risk Tolerances, evaluate the Company's risk priorities, and to monitor and evaluate the Company's risk profile as determined by management. Also, the Risk Committe oversee the composition and activities of the Bank's Operational Risk Committee ("ORC").

All members of the Committee are non-employee directors or other non-director, non-employee individuals. The Risk Committee in 2015 consisted of Directors Arnold (Committee Chairman), Downey, Guest, and Mullins, and three other non-directors, non-employees. The Committee met four times in 2015.

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

This section provides information regarding our compensation programs for our Chief Executive Officer, Chief Financial Officer and the three most highly compensated other executive officers (our "Named Executive Officers") for fiscal year 2015, including our overall compensation philosophy, components of compensation that we provide, and the objectives and intended incentives of our compensation programs. Our “Named Executive Officers” for fiscal year 2015 were as follows:

Name	Title	Age
Peter F. Benoist	President and Chief Executive Officer	68
Keene S. Turner	Executive Vice President and Chief Financial Officer	36
Scott R. Goodman	President - Enterprise Bank & Trust	52
Stephen P. Marsh	Executive Vice President, Chairman and Chief Credit Officer - Enterprise Bank & Trust	60
Frank H. Sanfilippo	Executive Vice President - Chief Operating Officer	53

Compensation Objectives

Principles. Our compensation philosophy is to provide competitive compensation that rewards executives for performance and management of risk. We develop and administer compensation programs consistent with the following principles:

• Compensation will include a substantial performance-based component which is:

• based on clearly defined goals;

• aligned with measurable business results, appropriate risk management and increase in stockholder value; and

• linked to successful implementation of our business plan.

• Compensation is designed to attract, motivate and retain valuable performers.

• Compensation will be fair and competitive based on market data.

Alignment. We believe our compensation system is operating consistent with these principles and that our executive compensation is aligned with the Company’s performance. Mr. Benoist’s total compensation, as measured in the Summary Compensation Table, has been reasonably correlated with performance of our stock, based on its year end closing price.

11

Stockholder Approval. Our stockholders have consistently approved our executive compensation program by high margins in every stockholder advisory vote on executive compensation that we have conducted. Last year, stockholders approved our executive compensation program by a ratio of 97.8% of votes cast. These votes are advisory and not binding upon the Committee, however the Committee takes the outcome of the votes into consideration in making executive compensation decisions. The Committee works with management and its outside advisors to provide improved disclosure of our executive compensation program in the Company’s proxy statements.

Overview of the Compensation Process

The Compensation Committee of the Board of Directors (the “Committee”) administers the Company's executive compensation programs under the authority of its charter. The Committee has responsibility for establishing, implementing and monitoring compliance with the Company's compensation philosophy.

The Committee has overall responsibility relating to compensation for the officers and other associates of the company. Other than with respect to Named Executive Officers, the Committee delegates certain of those functions to management. In the case of Named Executive Officers, the Committee establishes and reviews base salaries, short-term incentives, and long-term incentives, including measurement metrics and goals. With respect to executives below this level, the Committee reviews management's recommendations with respect to these matters. In the case of our non-executive associates, the Committee reviews, approves, and monitors overall compensation practices. The Committee retains oversight over compensation programs that are delegated to management, including evaluating compensation practices to determine that they do not encourage inappropriate risk to the Company.

Committee Agendas, Scheduling, and Keeping of the Minutes.The Committee Chairman, with input from the Committee, works with the Company's Senior Vice President of Human Resources, in preparing the agenda and calendar for the year. The Corporate Secretary takes minutes of the Committee's meetings. The Committee reviews and approves all minutes. The minutes are shared with the full Board upon approval.

12

Performance Reviews. Each of our executive officers performs an annual self-evaluation of his or her performance. Our Chief Executive Officer conducts performance evaluations or has final approval over performance evaluations for the other Named Executive Officers. The Executive Committee conducts the annual performance evaluation of our Chief Executive Officer, with input from the non-employee members of the Board. The Executive Committee discusses the Chief Executive Officer’s performance with the full board, excluding any employee directors and reports the Chief Executive Officer’s leadership rating to the Compensation Committee.

The performance review of our executive officers includes individual performance criteria consisting of financial and operational performance goals for specific lines of business, management of risk and development of teams and leadership.

The performance review of our Chief Executive Officer is based on the financial performance of the Company, the increase in stockholder value, growth in the human capital of the organization, succession planning, input from the outside members of the Board of Directors, the Company's overall management of risk, and development and execution of our strategy. The Committee discusses the Executive Committee's evaluation of the Chief Executive Officer without the Chief Executive Officer being present. A Committee member presents the Committee's decisions for compensation of each executive officer to the full Board of Directors.

Compensation Consultant. In 2015, the Committee again engaged Pay Governance to provide consulting services with respect to executive compensation. Pay Governance does not own any securities of the Company, nor do the consultants have any other business relationships with the Company or other individual associates. The Committee decides the nature and scope of any compensation consultant’s assignments and the Chairman of the Committee, with the Senior Vice President of Human Resources, approves the budget and invoices relating to consultants.

Pay Governance’s work for the Committee in 2015 included: (i) review and analysis of compensation data from the peer group of 23 companies discussed below for purposes of analyzing the competitiveness of the Company’s compensation for executive officers and (ii) providing business and technical advice on executive compensation matters, including short-term and long-term incentive compensation. In 2015, Pay Governance provided no material services to the Company separate from its service to the Committee.

Comparisons to Peer Group. The Committee uses competitive data to compare its compensation levels to a group of peer companies with respect to the following elements of compensation for Named Executive Officers:

• Base salary;

• Short-term annual incentives;

• Equity compensation elements such as performance contingent grants of stock; and

• Other elements that to date have been reported publicly under SEC rules.

• The Committee selects the peer group with the advice of the Company’s compensation consultant and input from management.

The peer group companies were selected to reflect financial institutions of comparable assets size to the Company with operations in markets that are geographically comparable to the Company’s markets. The Committee believes that these component companies represent institutions that compete for the Company’s talent pool. The Committee does not set rigid benchmarks for compensation of Named Executive Officers. The Committee's objective is to offer total target compensation for Named Executive Officers that is competitive with the Company's peers considering the relative performance of the executive and the Company. The Committee evaluates the competitiveness of the Company's executive compensation by comparisons to the peer group, including median compensation for executives having comparable responsibility at financial institutions of comparable asset size.

13

In 2015, our peer group consisted of the following 23 component companies:

Arrow Financial Corporation	Lakeland Financial Corp.
Bank of the Ozarks, Inc.	MidWest One Financial Group, Inc.
BNC Bancorp	Pinnacle Financial Partners Inc.
Cardinal Financial Corp.	QCR Holdings Inc.
CoBiz Financial Inc.	Republic Bancorp Inc.
Eagle Bancorp, Inc.	Simmons First National Corporation
Fidelity Southern Corporation	Southside Bancshares Inc.
Financial Institutions Inc.	Southwest Bancorp Inc.
First Financial Bankshares Inc.	Stock Yards Bancorp, Inc.
The First of Long Island	Suffolk Bancorp
Heartland Financial USA Inc.	Tompkins Financial Corporation
Home Bancshares, Inc. (Conway, AR)

As the Company's size and operations change, the Committee will evaluate, with the advice of its compensation consultants, whether changes should be made to the peer group.

In addition to comparisons to the peer group, and in the interest of taking internal equity into account, the Committee examines the relationship of one Named Executive Officer's total compensation and components to other Named Executive Officers.

Setting Compensation. The Committee considers the results of performance evaluations, peer group comparisons, and a review of the Company's goals and objectives. Based on this review, the Committee approves, and reports to the Board of Directors its decisions regarding the base salary, short term incentive compensation targets and long-term equity awards for our Named Executive Officers for the current year, as well as short term incentive compensation earned for the prior year.

Compensation Components

Our executive compensation consists of three components:

• base salary,

• short-term annual incentive awards, and

• long-term equity incentive compensation.

We also provide modest levels of perquisites, described later, to our Named Executive Officers. Named Executive Officers may elect to participate in a Deferred Compensation Plan that is available to certain other executives as well. We do not provide any executive benefits in the form of supplemental executive retirement plans, top hat plans, or special health care plans. Named Executive Officers also participate in other associate benefit programs that are provided or available to the general associate population such as health care, disability, life insurance and a defined contribution plan. These programs are described later. The Summary Compensation Table on page 24 provides additional information.

The Committee does not have a firm policy for the allocation of compensation components. Allocations of compensation among the various components are intended to align compensation with achievement of performance goals and appropriate risk management while remaining competitive in comparison to the Company’s peer group.

Base Salaries.We use base salary to recognize and compensate for requisite competencies, experience, and knowledge that we believe our Named Executive Officers must possess. In setting base salaries, the Committee considers the Named Executive Officer's experience, the difficulty that might be encountered in replacing the Named Executive Officer, and how limited the pool of qualified people might be. The Committee also considers comparisons to the peer group to determine competitive levels of base salary for Named Executive Officers.

With recommendations from the Chief Executive Officer and the Senior Vice President of Human Resources, the Committee annually reviews Named Executive Officer base salaries based on individual and Company performance, the individual's level of responsibility, peer group competitive data, internal equity considerations, compensation history, and terms and conditions of each Named Executive Officer's employment agreement.

14

Based on these factors, in 2015, the Committee approved increases in rates of base salaries for the Company's Named Executive Officers as follows:

Mr. Benoist    -    3%

Mr. Turner    -    25%

Mr. Goodman    -    8.5%

Mr. Marsh    -    3%

Mr. Sanfilippo    -    3%

Mr. Benoist, Mr. Marsh, and Mr. Sanfilippo received a standard merit increase. Mr. Turner and Mr. Goodman received market adjustments to appropriately reflect their responsibilities as Chief Financial Officer and President of the Bank, respectively.

Short-Term Annual Incentives. We use short-term incentive programs to drive an executive's performance in a given year by focusing on key goals. Our short-term incentive program sets a threshold, target and exceptional level of short-term incentive awards that a Named Executive Officer is eligible to earn. In the first quarter of each year, our Chief Executive Officer and the Senior Vice President of Human Resources, with the input of other members of management where appropriate, present proposed performance grids to the Committee for review and approval. For other executives, the Chief Executive Officer of the Company reviews the goals and sets the potential incentive amounts for each goal and performance level. The relative importance of each goal to all goals is determined. The relative weighting determines potential incentive payments for each goal. The Committee uses comparisons to the Company's peer group to determine target levels of payments.

For performance below threshold level of any goal, there is no payment with respect to that goal. Payout for performance falling between the threshold, target and exceptional levels is determined using straight-line interpolation. The Committee retains discretion to make awards above the exceptional level amount if actual performance exceeds exceptional level goals, subject to the maximum incentive amount permitted in the Annual Incentive Plan approved by our stockholders. Short-term annual incentives for 2015 were payable in cash.

The Company's 2015 short term incentive program utilized four goals that were applied across all Named Executive Officers. The Committee believes these goals align executives' incentives with the Company's stockholders and encourage superior performance in critical areas, such as efficient operations, profitability, prudent growth and effective risk management. The minimum target amount of annual incentives for Mr. Benoist is set forth in his employment agreement.

All Named Executive Officers had the same three Company performance goals and weightings for the 2015 Short-Term Incentive Plan. Following is a summary of the Company performance goals and the actual results of the Company for fiscal 2015.

(in thousands)	% Weight At Target	Threshold		Goals Target		Exceptional		Actual
Core Pre-Tax Income	40%	$	36,096	$	40,107	$	44,118	$	46,721
Core Deposits	20%	$	2,201,393	$	2,317,256	$	2,363,601	$	2,449,582
Core Fee Income	20%	$	22,641	$	25,157	$	27,673	$	25,576

The Core Pre-Tax Income goal is measured as income before tax expense without direct income and expenses related to purchased credit impaired ("PCI") assets, as well as an internal estimate of associated asset funding costs. The Committee has discretion to make adjustments for non-recurring or extraordinary items.

The Core Deposits goal is measured by calculating total deposits of the Company's banking subsidiary (excluding certificates of deposit).

The Core Fee Income goal is measured as the Company's noninterest income less gain or loss on sale of investment securities and components of noninterest income directly related to PCI assets.

In addition to the above three Company-based goals, 20% of each Named Executive Officer’s short term incentive award is based on his or her leadership rating. The “Leadership Rating” goal consists of a rating of between zero and four. The threshold level is a rating of two, the target level is a rating of three and the exceptional level is a rating of four.

15

Following is a summary of the value of short term incentive awards for Named Executive Officers in fiscal 2015 at the threshold, target and exceptional levels and the amount paid based on actual performance:

Name		Threshold		Target		Exceptional		Actual
Peter F. Benoist
	Award Value	$	87,500	$	175,000	$	262,500	$	247,914
						% of Target		141.7		%
Keene S. Turner
	Award Value	$	50,000	$	100,000	$	150,000	$	141,665
						% of Target		141.7		%
Scott R. Goodman
	Award Value	$	37,500	$	75,000	$	112,500	$	106,249
						% of Target		141.7		%
Stephen P. Marsh
	Award Value	$	37,500	$	75,000	$	112,500	$	106,249
						% of Target		141.7		%
Frank H. Sanfilippo
	Award Value	$	28,750	$	57,500	$	86,250	$	75,708
						% of Target		131.7		%

Long-Term Incentive Compensation. Our objectives for long-term incentive compensation for our Named Executive Officers include:

•Aligning incentives with increases in stockholder value;

•Using long-term incentives to attract and retain talented executives;

•Encouraging long-term risk management practices; and

•Using long-term incentives as a tool to define, encourage, and promote high performance.

The Committee also considers the comparisons to the 23 bank peer group discussed above to determine competitive levels of long-term incentive compensation and the share of total compensation comprised by long-term incentive awards.

Grants under the Long-Term Incentive Plan are currently in the form of performance contingent stock which vests upon achievement of performance goals during a three year performance period. Previously, the Company made awards using restricted stock units (“RSUs”) or shares of restricted stock. The Committee believes that awards of performance contingent stock provide more competitive equity incentive compensation to executives in comparison to the Company’s peers.

We believe the following characteristics of our Long-Term Incentive Plan provide our executive officers with incentives for long term performance and prudent risk-management:

• The value of awards are intrinsically tied to Company performance relative to a comparison group selected to represent

companies with performance characteristics similar to the Company’s;

•The plan clearly aligns interests of Company managers with the economic interests of stockholders;

•The incentives provide no value until the performance period is over and performance has been achieved;

•The plan facilitates retention of executives as awards are subject to a three year performance period; and

•The plan promotes stock ownership by management.

Compensation under the Long-Term Incentive Plan involves two steps:

16

• Grant: A participant first receives a “grant”, which is the setting of performance standards and the amount of incentives which will be awarded if those standards are satisfied. The performance period is typically three years.

• Award: If the performance standards are satisfied, the participant receives an “award” of the equity incentives. Currently, awards are in the form of fully vested shares of stock.

Each year management makes a recommendation to the Committee for grants to Named Executive Officers and pools of other associates of the Company. The Committee reviews this proposal in light of the Committee’s goals and philosophies for incentive compensation and marketplace information, including information provided by compensation consultants. The Committee makes the final determination of the amount and structure of grants to each Named Executive Officer. The Committee approves the aggregate value of grants and the performance goals applicable to non-executive associates. Grants for our Named Executive Officers are denominated in shares.

Awards for 2013-2015 Performance Period

Grants for the 2013-2015 Performance Period provided for the possibility of awards at a threshold, target and exceptional level based on the Company’s performance against two financial goals: (1) relative total shareholder return measured against a comparison group of 40 banks and bank holding companies with assets between $1.0 billion and $10.0 billion, commercial loans greater than 20% of total loans and consumer loans less than 10% of total loans, and (2) cumulative earnings per share. The institutions in the total shareholder return comparison group were selected because their size and mix of loan products allow for meaningful comparison of the Company’s performance.

The performance goals and actual performance for the period are set forth below:

Goal	Weight	Threshold Goal	Target Goal	Exceptional Goal	Actual
Relative Total
Shareholder Return	50%	50th percentile	65th percentile	90th percentile	94th percentile
Cumulative EPS	50%	$4.50 per share	$5.00 per share	$5.50 per share	$5.07 per share
	100%

In determining actual performance against the cumulative EPS goal, the Company excluded the effects (whether positive or negative) of (i) the prepayment which occurred in the fourth quarter of 2013 in connection with refinancing of an aggregate of $30.0 million of advances from the Federal Home Loan Bank of Des Moines at lower interest rates (ii) the prepayment which occurred in the fourth quarter of 2014 in connection with refinancing of an aggregate of $50.0 million of advances from the Federal Home Loan Bank of Des Moines at lower interest rates and (iii) the relocation of the Company’s wealth management group into the Company’s headquarters.

For each goal, achieving threshold performance pays at 50% of target value and achieving exceptional performance pays at 150% of target value. Based on the Company's actual performance during the performance period, in 2016 the Company paid the relative total shareholder return goal at the exceptional level and paid the cumulative earnings per share goal at 107% of the target level. This resulted in awards at 130% of the aggregate target level. Our Named Executive Officers received the following respective awards under the Long-Term Incentive Plan for the 2013-2015 performance period:

Named Executive	2013-2015 LTIP Award
Peter F. Benoist	35,492 shares
Scott R. Goodman	9,766 shares
Stephen P. Marsh	10,640 shares
Frank H. Sanfilippo	7,093 shares

The shares awarded were in the form of immediately vested common stock. Mr. Turner joined the Company in 2013 and his first grant of an opportunity under the long term incentive plan was for the 2014-2016 performance period.

Open Grants for 2014-2016 and 2015-2017 Performance Periods

Long-Term Incentive Plan grants are open with respect to the 2014-2016 and 2015-2017 performance periods. Grants for Named Executive Officers are reflected in the Summary Compensation Table on page 24 and the Grants of Plan-Based Awards table on

17

page 27. Subject to achievement of the performance goals described below, open grants to Named Executive Officers under these Long-Term Incentive Plans will be paid in the form of immediately vested shares of common stock.

2014 - 2016 Performance Period
Goal	Weight	Threshold Goal	Target Goal	Exceptional Goal
Total Shareholder Return	50%	50th percentile	65th percentile	90th percentile
Cumulative EPS	50%	$3.79 per share	$4.29 per share	$4.79 per share
	100%

2015 - 2017 Performance Period
Goal	Weight	Threshold Goal	Target Goal	Exceptional Goal
Total Shareholder Return	50%	50th percentile	65th percentile	90th percentile
Cumulative EPS	50%	$4.50 per share	$5.00 per share	$5.20 per share
	100%

Named Executive Officer Perquisites. We provide perquisites and other personal benefits to Named Executive Officers that we believe are reasonable and consistent with our overall compensation program. See the All Other Compensation - Supplemental Table on page 26 for more information on these items.

Retirement Plans. We expect executives to plan for and fund their own retirement through a defined contribution 401(k) plan and a Deferred Compensation Plan that permits certain executives to defer a limited portion of salary and bonus into any of several investment alternatives. The Company has historically provided an annual Company match to the 401(k) plan. There are no Company contributions to the Deferred Compensation Plan. We do not maintain defined benefit retirement or executive retirement plans or provide for post-retirement benefits.

Allocation of Compensation Components in 2015

We have entered into agreements with our NEOs granting them “double trigger” change in control severance benefits (i.e. the benefit is triggered if the executive is terminated or not offered continued employment upon a change in control of the Company). The amount of the change in control payment is generally two years’ combined base and annual incentive compensation. In addition, the Company's 2013 Incentive Stock Plan provides for vesting of outstanding awards and grants upon a change in control.

18

The Committee believes these agreements serve the best interests of the Company and its stockholders by ensuring that, in considering any proposed change in control, the NEOs would be able to advise the Board objectively about the transaction, without being unduly influenced by personal concerns such as the loss of employment following a change in control. These arrangements are also intended to promote stability and continuity of senior management. In addition, our agreements with our Named Executive Officers generally provide for severance payments upon a termination without cause of up to one year’s combined base and annual incentive compensation. Information on applicable payments under such agreements for Named Executive Officers is contained under the heading “Potential Payments Upon Termination or Change in Control” on page 30.

Section 162(m) of the Internal Revenue Code - Compensation Deductibility Limits

Section 162(m) generally limits the Company’s ability to deduct compensation in excess of $1 million to the Company's chief executive officer and four other highest compensated officers in any tax year. The Committee generally administers the Company’s long-term and short-term incentive plans to attempt to be eligible for deduction under Section 162(m). However, the Committee retains the flexibility to award compensation which does not meet the deductibility requirements of 162(m) if necessary to achieve the objectives described in this discussion.

Clawback Policy

The Company has voluntarily adopted a clawback policy permitting the Committee to recover incentive compensation paid to any executive officer (as defined under federal securities laws) based on materially inaccurate financial information or performance metrics. A copy of the clawback policy is available on the Company’s website at www.enterprisebank.com.

Stock Ownership Guidelines

The Company's stock ownership guidelines provide that non-employee directors and different levels of executives are expected to own a specific amount of our common stock within the later of five years of adopting the program or five years after the date the executive becomes a Named Executive Officer or director as applicable. Named Executive Officers and non-employee directors are expected to make continuing progress towards compliance with the guidelines during the five-year period. For purposes of determining whether an executive or non-employee director is in compliance, or making progress towards compliance, stock is valued at its purchase price or, in the case of stock awarded under the Company's compensation plan, at its value at the time of the Award. The table below shows the guidelines for Named Executive Officers by executive level.

TITLE	STOCK OWNERSHIP GOAL
Chief Executive Officer / President	Greater of 50,000 shares or 5 x Base Salary
All Other Named Executive Officers	Greater of 25,000 shares or 2.5 x Base Salary
Non-Employee Directors	$250,000*

*Non-employee directors are expected to own, or to acquire such amount within five years after the date of becoming a director.

Under the Company’s Insider Trading Policy, Directors and Officers are prohibited from engaging in hedging transactions related to Company stock, such as puts, calls, other derivative transactions, forward sale contracts swaps, and other arrangements intended to hedge exposure to Company stock or provide protection against declines in the value of Company stock.

EXECUTIVE EMPLOYMENT AGREEMENTS

Executive Employment Agreement with Mr. Benoist

Effective May 1, 2008, the Company entered into an Executive Employment Agreement with Mr. Benoist. The agreement, as amended, specifies that Mr. Benoist will serve as President and Chief Executive Officer until December 31, 2016. In exchange for Mr. Benoist's extension of his term of employment, the Company agreed to provide Mr. Benoist with a retention bonus opportunity. Under this arrangement, Mr. Benoist received two cash payments of $250,000 as he remained continuously employed with the Company through December 31, 2013 and December 31, 2014, respectively.

Mr. Benoist's agreement provides him with severance compensation in the event of his termination under certain circumstances. The agreement also has confidentiality and non-compete provisions for his period of employment and for a period of one year after termination of his employment.

The reason for termination determines the amount of severance compensation, if any, due to Mr. Benoist. Generally, he is entitled to payment of accrued base salary, bonus to the extent earned and payable, and accrued benefits through his date of termination. If the Company terminates Mr. Benoist “other than for cause”, he will also be paid as severance compensation the amount of one year base salary and the average of the two most recent years of annual incentives prior to his termination, subject to the execution of a release and waiver of all claims. If he is terminated in a “change in control,” he will be paid as severance compensation two years of base salary and target level bonus, paid in a discounted lump sum, and all unvested equity awards will become vested. Upon “voluntary” termination, termination “for cause”, disability or death, neither Mr. Benoist nor his estate will be entitled to any severance compensation.

Executive Employment Agreement with Mr. Turner

Effective as of September 13, 2013, the Company entered into a Key Executive Employment Agreement with Mr. Turner. Mr. Turner's agreement, as amended, provides for a continuous term until the agreement is terminated in accordance with its provisions. The agreement provides Mr. Turner with severance compensation in the event of his termination under certain circumstances. The agreement also has confidentiality and non-compete provisions for his period of employment and for a period of one year after termination of his employment.

Upon "termination other than for cause" (as defined in the agreement) Mr. Turner is entitled to payment of one year of base salary and target level bonus, paid in a period over one year, and all unvested equity awards will become vested.

If Mr. Turner's employment is terminated in a "change of control" he will be paid as severance two years of base salary and target level bonus in a lump sum payment 10 days after the change of control occurs, and all unvested equity awards will become vested. Upon any other termination, disability or death, neither Mr. Turner nor his estate will be entitled to any severance compensation.

Executive Employment Agreement with Mr. Goodman

Effective as of January 1, 2005, and amended on October 11, 2013, the Company entered into an Executive Employment Agreement with Mr. Goodman. The agreement provides for his continuous employment until the agreement is terminated in accordance with its provisions. The agreement provides Mr. Goodman with severance compensation in the event of his termination under certain circumstances. The agreement also has confidentiality and non-compete provisions for his period of employment and for a period of one year after termination of his employment.

Upon termination without "cause" (as defined in the agreement) or a "constructive termination" (as also defined in the agreement), Mr. Goodman is entitled to payment of one year of base salary and target level bonus, paid in a lump sum.

If Mr. Goodman's employment is terminated by the Company without cause or Mr. Goodman experiences a Constructive Termination (i) within three months prior to and in contemplation of a Change in Control (as defined in the agreement) or (ii) one year following a Change in Control, Mr. Goodman will be entitled to severance pay equal to two year's base salary, plus two times the target amount of his annual cash bonus opportunity for the year, paid in a lump sum, and all unvested equity awards will become vested for the year in which such termination occurs. Upon any other termination, disability or death, neither Mr. Goodman nor his estate will be entitled to any severance compensation.

Executive Employment Agreement with Mr. Marsh

Effective as of July 1, 2008, the Company entered into a Key Executive Employment Agreement with Mr. Marsh. The agreement, as amended, provides for a continuous term until terminated in accordance with its provisions.

The agreement provides Mr. Marsh with severance compensation in the event of his termination under certain circumstances. The agreement also has confidentiality and non-compete provisions for his period of employment and for a period of one year after

22

termination of his employment. The reason for termination determines the amount of severance compensation, if any, due to Mr. Marsh. Generally, he is entitled to payment of accrued base salary, bonus to the extent earned and payable, and accrued benefits through his date of termination. If the Company terminates Mr. Marsh “other than for cause,” he will also be paid as severance compensation the amount of 12 months base salary in a discounted lump sum. If he is terminated in a “change in control,” he will be paid as severance compensation two years of base salary and two years of target level bonus, paid in a discounted lump sum, and all unvested equity awards will become vested. Upon any other termination, disability or death, neither Mr. Marsh nor his estate will be entitled to any severance compensation.

Executive Employment Agreement with Mr. Sanfilippo

Effective as of December 1, 2004, the Company entered into a Key Executive Employment Agreement with Mr. Sanfilippo. Mr. Sanfilippo's agreement, as amended, provides for a continuous term until the agreement is terminated in accordance with its provisions. The agreement provides Mr. Sanfilippo with severance compensation in the event of his termination under certain circumstances. The agreement also has confidentiality and non-compete provisions for his period of employment and for a period of one year after termination of his employment.

The method of termination determines the amount of severance compensation, if any, due to Mr. Sanfilippo. Generally, he is entitled to payment of accrued base salary, bonus to the extent earned and payable, and accrued benefits through his date of termination.

Upon "termination other than for cause" (as defined in the agreement) Mr. Sanfilippo is entitled to payment of one year of base salary and target level bonus, paid in a single lump sum 60 days after termination.

If Mr. Sanfilippo is terminated in a “change in control,” or terminated “other than for cause” while the Company is engaged in bona fide discussions regarding a potential “change in control”, he will be paid as severance compensation two years of base salary and target level bonus, paid in a discounted lump sum, and all unvested equity awards will become vested. Upon any other termination, disability or death, neither Mr. Sanfilippo nor his estate will be entitled to any severance compensation.

NONQUALIFIED DEFERRED COMPENSATION

The following table sets forth information for each NEO during 2015 with respect to our Deferred Compensation Plan. Our Deferred Compensation Plan permits certain executives to participate and defer up to 25% of their base salary and/or up to 100% of their eligible bonus for a plan year. Participants can direct the investment of their accounts among the hypothetical investment alternatives made available under the plan and their accounts are adjusted for deemed investment gains or losses resulting from such investment directions. Participants make an irrevocable election when they elect to participate for a plan year to receive the vested account balance following their retirement date, or at a future date not less than five years after the beginning of the plan year. Participants may make hardship withdrawals under specific circumstances.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Historically, our Named Executive Officers have been entitled to severance and change in control compensation under certain termination of employment events. The amounts potentially payable to our NEOs under our Deferred Compensation Plan are set forth under the Nonqualified Deferred Compensation section above. The following table quantifies the amount of such compensation which would have been received if the terminations had occurred as of December 31, 2015. In the case of acceleration of unvested equity awards, the amount shown is based upon the closing price of $28.35 per share for our common stock as of December 31, 2015, and reflects the value of RSUs and the net cash equivalent due the holder offset by any exercise or "strike" price for stock options and SSARs.

RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING

FIRM - (Proposal A)

The Audit Committee has selected Deloitte & Touche LLP to be the independent registered public accounting firm for fiscal year 2016 and recommends that the stockholders ratify the appointment of the accounting firm. Although stockholder approval is not required by law and is not binding on the Audit Committee, the appointment is submitted by the Audit Committee of the Board of Directors in order to give the stockholders a voice in the designation of auditors. If the stockholders do not ratify the selection of Deloitte & Touche LLP, the engagement of Deloitte & Touche LLP, will not be affected for fiscal year 2016. However, the Audit Committee will review the selection of the independent registered public accounting firm for the next fiscal year. Even if the resolution is approved, the Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if it determines that a change would be in the best interest of the Company and its stockholders.

THE AUDIT COMMITTEE UNANIMOUSLY RECOMMENDS A VOTE FOR THE RATIFICATION OF

DELOITTE & TOUCHE LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC

ACCOUNTING FIRM.

ADVISORY (NON-BINDING) APPROVAL OF EXECUTIVE COMPENSATION — (Proposal B)

We are providing our stockholders the opportunity to vote on an advisory (nonbinding) resolution to approve our executive compensation as described in the section captioned “Compensation Discussion and Analysis,” the tabular disclosure regarding compensation of our NEOs and the narrative disclosure accompanying those tables, all as set forth in pages 11 through 30 of this proxy statement. Our Board determined, as a result of the latest advisory vote regarding how often the Company should include a say-on-pay vote in its proxy materials, that we will have such an advisory vote every year.

The following resolution is submitted for stockholder approval:

Resolved, that the stockholders approve the compensation of the Company’s Named Executive Officers, as disclosed in the Company’s proxy statement for the 2016 Annual Meeting of Stockholders, including the Compensation Discussion and Analysis, the tabular disclosure regarding compensation of our Named Executive Officers and the narrative disclosure accompanying those tables.

Because your vote is advisory, it will not be binding upon the Board, however the Board will take the outcome of this vote into consideration in making future executive compensation decisions.

For the reasons set forth in this Proxy Statement, including the Compensation Discussion and Analysis, and the Report of the Compensation Committee, we believe our compensation policies and procedures are centered on a pay-for-performance culture, are competitive in our marketplace, are strongly aligned with the long-term interests of our stockholders, and the compensation paid to our executives is consistent with such policies and procedures.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTEFORTHIS RESOLUTION.

All such loans and investments have been made in the ordinary course of business, have been made on substantially the same terms, including interest rate paid or charged and collateral required, as those prevailing at the time for comparable transactions with unaffiliated persons, and did not involve more than the normal risk of collectability or present other unfavorable features.

Review, Approval or Ratification with Related Persons

Our Code of Ethics requires that every employee and officer avoid situations where loyalties may be divided between our interests and the employee's own interests. Employees, officers and directors must avoid conflicts of interests that interfere with the performance of their duties or are not in our best interests.

Pursuant to its written charter, the Audit Committee reviews all related-party transactions as such term is used by ASC 850, Related Party Disclosures, or as otherwise required to be disclosed in our financial statements or periodic filings with the Securities and Exchange Commission, other than (a) grants of stock options made by the Board or any committee thereof or pursuant to an automatic grant plan, or (b) payment of compensation authorized by the Board or any committee thereof. Related party transactions include transactions between us, our executive officers and directors, beneficial owners of five percent or greater of our securities, and all other related persons specified under Item 404 of Regulation S-K promulgated by the Securities and Exchange Commission. The Audit Committee considers each proposed transaction in light of the specific facts and circumstances presented, including but not limited to the risks, costs and benefits to us.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires directors, certain officers and all persons who beneficially own more than 10 percent of our Common Stock file reports with the Securities and Exchange Commission with respect to beneficial ownership of our Securities. We have adopted procedures to assist our directors and executive officers in complying with the Section 16(a) filings.

Based solely upon our review of the copies of the filings that we received with respect to the fiscal year ended December 31, 2015, or written representations from certain reporting persons, we believe that all reporting persons except Mr. Murphy and Mr. Mullins made all filings required by Section 16(a) in a timely manner. Mr. Murphy filed one late Form 4, relating to the gift of shares to a gift trust that occurred during 2012, and Mr. Mullins filed one late Form 4, relating to the gift of shares to a family trust that occurred during 2014.

AUDIT COMMITTEE REPORT

The Audit Committee submits the following report:

The Audit Committee's role includes assisting the Board of Directors in monitoring the integrity of the Company's financial statements and related reporting process, compliance by the Company with legal and regulatory requirements, the independent auditors' qualifications, independence and performance, performance of the Company's internal audit function and the business practices and ethical standards of the Company. The Audit Committee operates under a written charter approved by the Board of Directors.

Management is responsible for the Company’s internal controls and financial reporting process. The Company's independent auditor, Deloitte and Touche LLP, is responsible for performing an independent audit of the Company’s consolidated financial statements and internal control over financial reporting in accordance with standards of the Public Company Accounting Oversight Board (United States) ("PCAOB") and to express its opinions on the Company's financial statements in accordance with U.S. generally accepted accounting principles and the Company's internal control over financial reporting. The Audit Committee’s responsibility is to monitor and oversee these processes. In addition, the Audit Committee is directly responsible for the appointment and oversight of the independent auditors, including review of their qualifications, independence and performance.

The Audit Committee has reviewed and discussed the Company’s audited financial statements and internal control report with management and the independent auditors. The Audit Committee discussed with the independent auditors the matters required by PCAOB Auditing Standard No. 16, Communications with Audit Committees as modified or supplemented, the rules of the SEC and other regulations. The Audit Committee received written disclosures and the letter from the independent auditors as required by PCAOB Rule 3526 - Independence regarding the independent accountant's independence and discussed with the auditors their independence. As part of its review, the Audit Committee reviewed the fees paid to Deloitte & Touche and considered whether Deloitte & Touche's performance of non-audit services for the Company was compatible with auditors' independence. The Audit Committee has concluded that Deloitte & Touche is independent from the Company and its management.

Based on the reports and discussions described above, the Audit Committee recommended to the Board of Directors that the Company’s audited financial statements be included in its Annual Report on Form 10-K for the year ended December 31, 2015 for filing with the Securities and Exchange Commission.

Respectfully submitted by the following independent directors, who comprise the Audit Committee,
	Sandra A. Van Trease	William H. Downey	Robert E. Guest, Jr.
	Chairperson
		James M. Havel	John Q. Arnold

The foregoing report of the Audit Committee does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other Company filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent the Company specifically incorporates the report by reference therein.
