Important Notice Regarding the Availability of Proxy Materials for the
Shareholder Meeting to be Held on April 28, 2016

The proxy statement and the Company's annual report on Form 10-K are available at www.cardinalbank.com/InvestorRelations/2016ProxyMaterials

This Proxy Statement is furnished to holders of common stock, par value $1.00 per share ("Common Stock"), of Cardinal Financial Corporation (the "Company") in connection with the solicitation of proxies by our Board of Directors to be used at the 2016 Annual Meeting of Shareholders to be held on April 28, 2016 at 10:00 A.M., at the Fair Lakes Hyatt, 12777 Fair Lakes Circle, Fairfax, Virginia, and at any adjournment thereof (the "Meeting"). At the Meeting, three directors will be elected for a term of three years each. Shareholders will also be asked to approve a non-binding resolution to endorse the Company's executive compensation program and to ratify the appointment of Yount, Hyde & Barbour, P.C. as the Company's independent auditors for 2016.

Our principal executive offices are located at 8270 Greensboro Drive, Suite 500, McLean, Virginia 22102. The approximate date on which this Proxy Statement and the accompanying proxy card are being mailed to our shareholders is March 24, 2016.

The Board of Directors has fixed the close of business on March 1, 2016 as the record date (the "Record Date") for the determination of the holders of shares of Common Stock entitled to receive notice of and to vote at the Meeting. At the close of business on the Record Date, there were 32,533,465 shares of Common Stock outstanding held by 628 shareholders of record. Each share of Common Stock is entitled to one vote on all matters to be acted upon at the Meeting.

As of February 29, 2016, our directors and executive officers and their affiliates, as a group, owned of record and beneficially a total of 2,069,576 shares of Common Stock, or approximately 6.23% of the shares of Common Stock outstanding on such date. Our directors, which include the nominees for election, and our executive officers have indicated an intention to vote their shares of Common Stock FOR the election of the nominees set forth on the enclosed proxy, FOR the approval of the non-binding resolution to endorse the Company's executive compensation program and FOR the ratification of Yount, Hyde & Barbour, P.C. as our independent auditors for 2016.

A shareholder may abstain or (only with respect to the election of directors) withhold his vote (collectively, "Abstentions") with respect to each item submitted for shareholder approval. Abstentions will be counted for purposes of determining the existence of a quorum. Abstentions will not be counted as voting in favor of or against the relevant item.

A broker who holds shares in "street name" has the authority to vote on certain items when it has not received instructions from the beneficial owner. Except for certain items for which brokers are prohibited from exercising their discretion, a broker is entitled to vote on matters presented to shareholders without instructions from the beneficial owner. "Broker shares" that are voted on at least one matter will be counted for purposes of determining the existence of a quorum for the transaction of business at the Meeting. Where brokers do not have or do not exercise such discretion, the inability or failure to vote is referred to as a "broker nonvote." Under the circumstances where the broker is not permitted to, or does not, exercise its discretion, assuming proper disclosure to us of such inability to vote, a broker nonvote will not be counted as voting in favor of or against the particular matter, or otherwise as a vote cast on the matter. A broker cannot vote without instructions on the election of directors or on the approval of the non-binding resolution to endorse the Company's executive compensation program; therefore, there may be broker nonvotes on Proposals 1 and 2. A broker may vote on the ratification of the appointment of our independent auditors; therefore, no broker nonvotes are expected to exist in connection with Proposal 3. Abstentions and broker nonvotes will have no effect on the outcome of any of the Proposals.

Our shareholders are requested to complete, date and sign the accompanying form of proxy and return it promptly to us in the enclosed envelope. If a proxy is properly executed and returned in time

for voting, it will be voted as indicated thereon. If no voting instructions are given, proxies received by us will be voted for election of the directors nominated for election, for the approval of the non-binding resolution to endorse the Company's executive compensation program and for the ratification of Yount, Hyde & Barbour, P.C. as our independent auditors for 2016.

Shareholders can also deliver proxies by using the Internet. The Internet voting procedures are designed to authenticate shareholders' identities, to allow shareholders to give their voting instructions and to confirm that such instructions have been recorded properly. Instructions for voting over the Internet are set forth on the enclosed proxy card. If your shares are held in street name with your bank or broker, please follow the instructions enclosed with this Proxy Statement.

Any shareholder who executes a proxy has the power to revoke it at any time before it is voted by giving written notice of revocation to us, by executing and delivering a substitute proxy dated as of a later date to us or by attending the Meeting and voting in person. If a shareholder desires to revoke a proxy by written notice, such notice should be mailed or delivered, so that it is received on or prior to the date of the Meeting, to Jennifer L. Deacon, Secretary, Cardinal Financial Corporation, 8270 Greensboro Drive, Suite 500, McLean, Virginia 22102. If your shares are held in street name with your bank or broker and you want to change or revoke voting instructions you have given to the record holder of your shares, please follow the directions given by your bank or broker.

We will pay all of the costs associated with this proxy solicitation. In addition, certain of the officers and employees of the Company or our subsidiaries, without additional compensation, may use their personal efforts, by telephone or otherwise, to obtain proxies. We will also reimburse banks, brokerage firms and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses in forwarding proxy materials to the beneficial owners of the shares.

The following table sets forth certain information, as of February 29, 2016, with respect to beneficial ownership of shares of Common Stock by each of the members of the Board of Directors (including the nominees for election to the Board of Directors), by each of the executive officers named in the "Summary Compensation Table" below and by all directors, nominees and executive officers as a group.

The following table sets forth information, as of December 31, 2015, regarding the number of shares of Common Stock beneficially owned by all persons known by us who own five percent or more of our outstanding shares of Common Stock.

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires our directors and executive officers, and any persons who beneficially own more than 10% of the outstanding shares of Common Stock, to file with the Securities and Exchange Commission ("SEC") reports of ownership and changes in ownership of shares of Common Stock. Directors and executive officers are required by SEC regulations to furnish us with copies of all Section 16(a) reports that they file, and we assist these individuals in this process. Based upon a review of SEC Forms 3, 4, and 5 and based on representations that no Forms 3, 4, and 5 other than those already filed were required to be filed, we believe that, except as disclosed below, all Section 16 (a) filing requirements applicable to those certain

executive officers, directors, and beneficial owners of more than 10% of our Common Stock were timely met during the year ended December 31, 2015.

Certain of our directors and officers participate in our deferred income plan pursuant to which they receive deferred stock units each pay period for the amount of compensation that they defer. During the year ended December 31, 2015, the following reports were not timely filed in connection with the receipt of these deferred stock units. Each of these reports covered a single deferred stock unit transaction: Mr. Beck—fifteen reports; Mr. Bergstrom—twenty-seven reports; Mr. Buck—fifteen reports; Mr. Clineburg—twenty-seven reports; Mr. Dewberry—fifteen reports; Ms. Frazier—twenty-seven reports; Mr. Garcia—fifteen reports; Mr. Lambert—fifteen reports; Ms. Lang—fifteen reports; Mr. Peterson—fifteen reports; Mr. Reynolds—twenty-seven reports; Ms. Starr—fifteen reports; Mr. Wendel—twenty-seven reports and Mr. Wiltse—fifteen reports.

Under our Articles of Incorporation and Bylaws, the Board of Directors is divided into three classes as nearly equal in number as possible. Normally, directors in only one class are elected each year, each for a three-year term on the Board. This year, the class of directors whose terms expire in 2016 are up for election. In the election of directors, those receiving the greatest number of votes will be elected even if they do not receive a majority.

The Nominating Committee of the Board of Directors selected the nominees for election as directors. The Board of Directors has no reason to believe that any of the nominees will be unavailable.

The business and affairs of the Company are managed under the direction of the Board of Directors in accordance with the Virginia Stock Corporation Act and our Articles of Incorporation and Bylaws. Members of the Board are kept informed of our business through discussions with the Executive Chairman and other officers, by reviewing materials provided to them and by participating in meetings of the Board of Directors and its committees.

In February 2016, we split the positions of Chairman and Chief Executive Officer, which were previously held by the same officer, Mr. Clineburg. This change was made as a result of our beginning our leadership transition within the Company. The former structure was previously appropriate in light of Mr. Clineburg's role, particularly with respect to the risk oversight function as Mr. Clineburg has over 40 years experience in the banking industry, in particular in the Washington, D.C. area. As Executive Chairman, Mr. Clineburg will focus on a seamless transition in leadership along with corporate strategy and mergers and acquisitions. Mr. Bergstrom, as President and Chief Executive Officer will be responsible for the day to day oversight and management of the Company. We believe this structure is now appropriate for our organization as leadership responsibilities transfer to Mr. Bergstrom. Along with the Board of Directors and its various committees as discussed below, both Mr. Clineburg and Mr. Bergstrom will now provide the necessary oversight over the Company's various risks. We operate in the banking industry, which is impacted heavily by credit risk, market risk, interest rate risk, investment risk, liquidity risk, fiduciary risk and reputational risk. Each of these types of risks are managed on a regular basis, and most times daily. Mr. Clineburg and Mr. Bergstrom participate in various internal risk committees to provide guidance and leadership through certain risks that the Company faces. Mr. Clineburg also has successfully executed a turnaround, and his vision and leadership have been instrumental in the strong performance of the organization, which will be invaluable support to Mr. Bergstrom as he begins his new role with the Company.

In addition, we have a Lead Director to provide independent oversight over the Board of Directors. Our Lead Director, Mr. Dewberry, is responsible for leading the meetings of the Independent Directors. In conjunction with the Nominating Committee, he is charged with managing the nominations process for the Board of Directors. In addition, our Lead Director is responsible for chairing the meetings of the Board of Directors at times when our Executive Chairman is not available to do so, or when there may be a potential conflict of interest. He also serves as a non-exclusive conduit to the Executive Chairman of the views and concerns of the Independent Directors.

Risk management is an integral part of the responsibilities held by the Board of Directors. The risks that are inherent to our business include but are not limited to credit risk, market risk, interest rate risk, investment risk, liquidity risk, fiduciary risk and reputational risk. The Board of Directors discusses risks related to our business strategy as part of their overall decision making process. In addition, the majority of our Board of Directors serve on one or more committees that oversee the management of the risks identified above. In addition to the daily oversight and management of risk by management, our Executive Chairman and our President and Chief Executive Officer discussed above, certain risks are managed by our committees with expertise in those areas.

The Audit Committee has oversight over our accounting and financial reporting processes and the audits of the Company's financial statements. This committee, through the assistance of our Internal

Audit Group, identifies the significant risks or exposures of the organization and completes a risk assessment. In addition, the committee assesses the steps taken by our management team to minimize these risks to the organization.

The Compensation Committee assists the Board in the fulfillment of its risk oversight responsibilities with respect to executive compensation. The primary purpose of the Compensation Committee is to ensure that the compensation and benefits for senior management and the Board of Directors is fair and appropriate, is aligned with the interests of our shareholders and does not pose a risk to the financial health of the Company or its affiliates.

Our Loan Committee is charged with the responsibility of maintaining both a quality loan portfolio and a strong credit culture throughout the organization. The members of this committee are involved in the risk-decision process which is managed in a disciplined fashion to maintain an acceptable risk profile characterized by soundness, diversity, quality, prudence, balance and accountability.

The Board of Directors has determined that 10 of its 11 members are independent as defined by the listing standards of the Nasdaq Stock Market ("Nasdaq"), including the following: Messrs. Beck, Buck, Dewberry, Garcia, Lambert, Nassetta, Peterson, and Wiltse and Ms. Lang and Ms. Starr. In reaching this conclusion, the Board of Directors considered that the Company and its subsidiaries conduct business with companies of which certain members of the Board of Directors or members of their immediate families are or were directors or officers. See "Certain Relationships and Related Transactions" below for additional information on certain transactions with members of our Board of Directors. There were no other transactions, relationships or arrangements between the Company and any of our independent directors.

Our Code of Ethical Conduct applies to all of our directors, officers and employees (collectively, "Employees"). It is a standard for responsible and professional behavior that should serve as a guide for all business dealings. Our Code requires:

Ethical business conduct and compliance with all local, state and federal laws, rules and regulations are vital in maintaining the public's trust and confidence. In all our endeavors, two fundamental principles will apply:

Each Employee is required to be aware of the principles in the Code, to adhere to its guidelines, and to seek assistance from senior management, supervisory personnel, or the Human Resources Department when any questions arise about the Code, or when a situation develops that may present a problem under the Code. The Code provides a mechanism for Employees to report potential violations anonymously, and we do not permit retaliation of any kind against Employees for good faith reports of ethical violations. Our Board of Directors exercises reasonable oversight with respect to the implementation and effectiveness of this Code. Our Code of Ethics can be found on our website at www.cardinalbank.com.

The Board of Directors holds regular meetings each year, including an annual meeting. During 2015, the Board of Directors held 12 regular meetings and two special meetings. Each director attended at least 75% of the aggregate of the 2015 meetings of the Board of Directors and its committees on which he or she served.

Independent directors meet periodically outside of regularly scheduled Board meetings. Sidney O. Dewberry serves as our Lead Director and oversees the meetings. The Independent directors met once during 2015.

We encourage the members of our Board of Directors to attend the Annual Meeting of Shareholders. At last year's Annual Meeting of Shareholders, all of the directors were in attendance.

The Board of Directors has an Executive Committee, an Audit Committee, a Compensation Committee, a Loan Committee, and a Nominating Committee. All Committees met at various times during 2015. Specific information regarding the Audit Committee, the Compensation Committee and the Nominating Committee is presented below.

The Audit Committee consists of Mr. Lambert, as Chairman, Messrs. Beck, Peterson and Wiltse and Ms. Starr. The Board of Directors has determined that each of the members of the Audit Committee is independent in accordance with Nasdaq's listing standards and the requirements of the SEC. The Board of Directors has also determined that all of the members of the Audit Committee have sufficient knowledge in financial and auditing matters to serve on the Audit Committee and that Mr. Lambert qualifies as an "audit committee financial expert" as defined by regulations of the SEC.

The Audit Committee has adopted a charter, which provides guidance to the committee, the entire Board and the Company regarding its purposes, goals, responsibilities, functions and its evaluation. The Audit Committee Charter is attached as Exhibit A to this Proxy Statement. The Audit Committee is responsible for the selection and recommendation of the independent accounting firm for the annual audit. It reviews and accepts the reports of our independent auditors, internal auditor, and federal and state examiners. The Audit Committee met eight times during the year ended December 31, 2015.

Additional information with respect to the Audit Committee is discussed under "Audit Information" below.

The Compensation Committee consists of Mr. Buck, as Chairman, and Messrs. Dewberry, Garcia and Peterson, all of whom the Board in its business judgment has determined are independent as defined by Nasdaq's listing standards and the requirements of the SEC. The Compensation Committee reviews senior management's performance and compensation and reviews and sets guidelines for compensation of all employees. The Compensation Committee met eight times during the year ended December 31, 2015.

The Compensation Committee has adopted a charter, which provides guidance to the Compensation Committee, the Board of Directors and the Company regarding the administration of the compensation programs and policies of the Company. The Compensation Committee is responsible for maintaining compensation policies that support our achievement of overall goals and objectives and that such policies are designed with full consideration of all of our accounting, tax, securities law, and regulatory requirements. A copy of the charter is included as Exhibit B to this Proxy Statement.

Additional information with respect to the Compensation Committee is discussed under "Executive Compensation" below.

The Nominating Committee consists of Mr. Dewberry, as Lead Director, and Messrs. Beck, Buck, Garcia, Lambert, Nassetta, Peterson, Wiltse and Ms. Lang and Ms. Starr. The Board of Directors in its business judgment has determined that all members involved in the nominations process are independent as defined by Nasdaq's listing standards. As the Nominating Committee selects the nominees for election as directors, our Board of Directors currently believes it is important that all of our independent directors participate in the nomination process in order to bring multiple perspectives within the evaluation process for incumbent directors as well as nominations of potential candidates to the Board of Directors. The Nominating Committee is responsible for selecting and recommending to the Board of Directors with respect to (i) nominees for election at the Annual Meeting of Shareholders and (ii) nominees to fill Board vacancies. The Nominating Committee does not have a charter that governs the nominations process. The Nominating Committee met once during the year ended December 31, 2015.

In identifying potential nominees, the Nominating Committee takes into account such factors as it deems appropriate, including the current composition of the Board of Directors to ensure diversity among its members. Diversity includes the range of talents, experiences and skills that would best complement those that are already represented on the Board, the balance of management and independent directors and the need for specialized expertise. The Nominating Committee considers candidates for Board membership suggested by its members and by management and the Nominating Committee will also consider candidates suggested informally by a shareholder of the Company.

The Nominating Committee believes that the following guidelines are the standards by which potential nominees should be evaluated:

Shareholders entitled to vote for the election of directors may recommend candidates for the Nominating Committee to consider formally in connection with an annual meeting. Information with respect to shareholder nominations is discussed under "Proposals for 2017 Annual Meeting" below.

Under the process used by us for selecting new candidates to the board of directors, the Nominating Committee, identifies the need to add a new board member with specific qualifications or to fill a vacancy on the board. The Executive Chairman may also provide input in the nominations process. The Lead Director will initiate a search, working with staff support and seeking input from the board of directors and senior management, hiring a search firm, if necessary, and considering any candidates recommended by shareholders. An initial slate of candidates that will satisfy criteria and otherwise qualify for membership on the board may be presented to the Nominating Committee. A determination is made as to whether members of the board have relationships with preferred candidates and can initiate contacts. At least one member of the Nominating Committee, along with the Executive Chairman, interviews prospective candidates. The Nominating Committee meets to conduct further interviews of prospective candidates, if necessary or appropriate, and to consider and recommend final candidates for approval by the full board of directors.

The following table shows the compensation earned by each of the directors for service as a director during 2015. Mr. Clineburg's compensation earned for his services as a member of the Board of Directors is included in the "Executive Compensation" section below.

Each director is entitled to receive cash compensation for his or her service on the Board of Directors. Each director is paid an annual retainer of $5,000, $3,000 for each Board meeting attended, $2,250 for each Executive Committee meeting attended, and $1,750 for each committee meeting attended. J. Hamilton Lambert, in his capacity as Audit Committee Chairman, receives an additional retainer of $16,000 annually.

Each non-employee director can participate in our deferred income plan for non-employee directors. Under this plan, a non-employee director may elect to defer all or a portion of any director-related fees including retainers and fees for serving on board committees. Director deferrals are matched 50% by us and are vested immediately. Such match is not to exceed $50,000 in any particular plan year.

Shareholders and other interested parties may communicate directly with the Board of Directors. All communications should be directed to our Corporate Secretary at the address below and should prominently indicate on the outside of the envelope that it is intended for the Board of Directors or for non-management directors.

The primary objective of our executive compensation program is to attract and retain highly skilled and motivated executive officers that significantly contribute to the company's success. The executive officers are expected to manage the Company to promote its growth and profitability, minimize risk, leading to long term value for our shareholders. As such, the compensation program is designed to provide levels of compensation that reflect the executive's role in the organization and reward both the individual's and the organization's performance. We assess our executive officers' performance both objectively and subjectively using both financial measures (such as return on average assets, return on average equity, efficiency ratio, credit quality, net income to target and total return to shareholders) and non-financial goals and objectives (including strategic objectives, safety and soundness, risk management and service to the community). The Compensation Committee (the "Committee") believes that evaluating performance in this manner aligns the interests of our executive officers with the achievement of long-term sustainable financial performance and resulting increases in shareholder value. We believe that our compensation program contributes to achieving these results.

At our 2015 Annual Meeting of Shareholders, approximately 52% of the shareholders who voted on the "say on pay" proposal approved the compensation we pay to our named executive officers.

In making decisions regarding its executive compensation program, the Committee has considered specific comments received from shareholders, including those in connection with the advisory vote on executive compensation. The Committee has undertaken an effort to re-evaluate the appropriateness and competitiveness of the Company's total compensation program in light of shareholder feedback generally and to ensure the Company's executive compensation program represents the best interests of shareholders. The Committee is committed to performing a thorough assessment and making changes as deemed necessary to attract and retain the highest quality talent in a very competitive labor market, to reward for achieving the Company's objectives, and to align with the best interests of the Company and its shareholders.

In response to shareholder concerns, the Committee approved two policies (1) stock ownership and retention guidelines for its named executive officers and (2) a formal compensation recovery (clawback) policy for its named executive officers. Both of these policies are discussed below.

We reported record net income of $47.3 million, or $1.43 per diluted common share, for the year ended December 31, 2015, compared to net income of $32.7 million, or $1.00 per diluted common share, in 2014. Net interest income increased $8.7 million to $116.4 million for the year ended December 31, 2015, compared to $107.7 million for the year ended December 31, 2014, a result of increase in interest earning assets. Provision for loan losses was $1.4 million for the year ended December 31, 2015, compared to $1.9 million for 2014. Non-interest income increased $13.5 million to $52.7 million for the year ended December 31, 2015 as compared to $39.2 million for 2014 due primarily to an increase in realized and unrealized gains on mortgage banking activities from our mortgage banking business segment. Non-interest expense was $96.3 million for the year ended December 31, 2015 compared to $96.2 million for the year ended December 31, 2014.

Organic balance sheet growth continued as at December 31, 2015, total assets were $4.03 billion, an increase of 18.6%, or $630.8 million, from $3.40 billion at December 31, 2014. Total loans

receivable, net of deferred fees and costs, increased 18.4%, or $475.2 million, to $3.06 billion at December 31, 2015, from $2.58 billion at December 31, 2014. Total deposits increased 19.6%, or $497.4 million, to $3.03 billion at December 31, 2015, from $2.54 billion at December 31, 2014.

Shareholders' equity at December 31, 2015 was $413.1 million, an increase of $35.8 million from $377.3 million at December 31, 2014. The increase in shareholders' equity was attributable to the recognition of net income of $47.3 million less dividends paid to shareholders totaling $14.2 million for the year ended December 31, 2015. Book value per share at December 31, 2015 and 2014 was $12.76 and $11.76, respectively. Total risk-based capital to risk-weighted assets was 11.37% at December 31, 2015 compared to 11.78% at December 31, 2014. Accordingly, we were considered "well capitalized" for regulatory purposes at December 31, 2015.

The principal elements of our executive compensation program are annual base salary, short-term incentive compensation through annual cash bonuses, long-term incentives through the grants of equity-based awards and participation in our deferred income plans. In addition, we provide our executives with benefits that are generally available to all of our salaried employees.

We view the principal elements of our executive compensation as related but distinct, and target to deliver competitive annual total compensation opportunities to the Company's executive officers commensurate with individual and Company performance. Our Compensation Committee has not adopted any formal policies or guidelines for allocating total compensation between long-term and short-term compensation, between cash and non-cash compensation, or among different forms of compensation. We determine the appropriate level for each compensation element based, in part, but not exclusively, on our view of internal equity and consistency, performance, the competitive landscape and other information we deem relevant. We believe that equity-based awards are the primary motivator in attracting and retaining executives over the long-term and align executives' interests with those of our shareholders, and that salary and cash bonuses are important considerations in the short-term.

Annually, our Compensation Committee performs a strategic review of our executive officers' total compensation and Company stock holdings. Through this review, the Committee determines whether they adequately compensate our executive officers for both individual and organizational results, relative to external compensation benchmarks. The Committee considers the Company's internal objectives (financial and non-financial), the individual executive's contribution to Company objectives, external peer compensation levels and peer performance in making annual compensation decisions for the Company's executive officers. The Committee also receives annual evaluations prepared by the Executive Chairman regarding the performance of each executive officer. As part of the process, the Committee also evaluates the performance of the Executive Chairman and of the President and Chief Executive Officer each year and makes all decisions regarding their base salary adjustments and short and long term incentive payments. The Executive Chairman and President and Chief Executive Officer are not present during any deliberations regarding their compensation.

The Committee approved a formal Compensation Recovery (clawback) Policy during the past year. In the event the Company is required to prepare an accounting restatement due to material noncompliance with any financial reporting requirement under securities laws, the named executive officers shall reimburse the Company for or forfeit any bonus or other incentive-based or equity-based compensation received by that person during the fiscal year preceding the accounting restatement. This policy applies to current and former named executive officers of the Company.

The Committee has committed not to enter into any future executive arrangements with a tax gross-up provision of any kind. Only one legacy agreement exists with a gross-up provision.

The Company's compensation program fosters long term equity ownership and is specifically designed to align the interests of executives with those of our shareholders. All named executive officers build equity ownership through purchases in the open market, contributing their own funds into the Company's 401(k) plan and its Executive Deferred Income Plan, through purchases of our Common Stock through an option exercise, and through vesting of restricted stock units. During the past year, the Committee approved stock ownership retention guidelines for its named executive officers. This policy requires that the Chief Executive Officer hold shares of the Company's Common Stock equal to three times their base salary. For all other named executive officers, the policy states that they are required to hold shares of our Common Stock equal to two times their respective base salaries. In the instance a named executive officer does not meets their ownerhsip guideline, the executive may only execute up to 50% of their stock option exercise (net of tax) to sell into the open market. The remaining 50% of the shares within the option exercise are required to be owned by the executive. There is no target date to retain ownership in our Common Stock and the value of their ownership is based on our one-year average market price of our Common Stock at the end of each calendar year. As of December 31, 2015, all named executive officers meet and/or exceed the stock ownership retention guidelines.

The Compensation Committee has authority over the selection, use, and retention of any compensation consultant or any other experts engaged to assist the Committee in discharging its responsibilities. During 2015, the Committee engaged an independent compensation consultant, Pearl Meyer (PM). PM is a recognized leader in executive compensation strategy and governance. Additionally, PM has significant experience with community banks and the related compensation practices. PM assisted the Committee in its assessment of the compensation peer group and executive compensation benchmarking. These are the only services performed PM for the Committee and PM had no other relationship with the Company or its management, nor did it provide any other services to the Company. In accordance with NASDAQ and SEC rules, the Compensation Committee assessed the independence of PM and concluded that no conflicts of interest exist that would prevent PM from providing independent and objective advice to the Committee.

During 2014 as part of its annual review, the Committee performed an assessment of our compensation peer group. The assessment compared the Company's current asset size, financial performance and economic and geographic market to our original peer group. In addition, the Committee, along with the guidance of its consultant, analyzed publicly traded bank holding companies in metropolitan areas similar to the Washington MSA within the geographic region of Atlanta, Georgia to Boston, Massachusetts. As a result of this additional analysis, a new peer group was developed during 2014 to include a select group of eighteen publicly traded banks in similar metropolitan areas. At December 31, 2015, institutions in our peer group had median assets of $4.7 billion and a median market cap of $711 million. Furthermore, because the Company has a diversified revenue stream which includes a mortgage company that generates significant fee revenue, the selection criteria included companies with revenue as a percentage of assets between 3.04% to 5.36%. Finally, the analysis considered total shareholder return over a one year, three year and five year period of time. The Committee believes the competitive characteristics and business mix of the major metropolitan areas in which the new peer group operates aligns closely with the Washington MSA demographics. Our objective in peer group selection is to position the Company near the median of the peer group size, while also considering the comparability of business and the quality of each comparator.

During the annual review of the compensation peer group performed by the Committee in 2015 (with the assistance of PM), it was determined that no changes to the peer group were necessary for 2015. Hudson Valley Holding Corporation was removed from the peer group due to acquisition.

In addition to determining the adequacy of the total compensation offered to our executive officers compared to peers, we compare our performance to the peer group using twelve financial performance measures as well as total shareholder return. As of December 31, 2015, the Company compared very favorably to its peers and was near the 75th percentile of the peer group in both the unweighted average of shareholder return and the unweighted average of the twelve financial measures, including measures used for internal targets. The financial results for 2015 also exceeded the unweighted three-year average for Cardinal's twelve financial measures. The three-year average includes financial results for 2013 which were negatively affected by the results of the mortgage subsidiary and placed the Company in the bottom quartile of financial performance. It is to be noted that in keeping with the Company's compensation practices, the named executive officers did not receive any short term incentive compensation for 2013's performance. Since that time, the Company's financial performance

has returned to its historical top quartile performance for both 2014 and 2015. Below are two tables that report the results of the peer group analysis:

In February 2016, Mr. Clineburg transitioned to Executive Chairman while remaining Principal Executive Officer. Christopher W. Bergstrom, formerly the Regional President of Cardinal Bank and Chief Risk Officer of the Company, was appointed President and Chief Executive Officer of the Company.

As a result of the transition to Executive Chairman, the Committee offered, which Mr. Clineburg accepted, an additional three-year term with the amendment to his existing employment agreement. Furthermore, the Committee worked with PM to evaluate Mr. Clineburg's current retirement package. It was their desire to commend Mr. Clineburg for the outstanding performance of the Company during his 15 year tenure by offering additional retirement benefits and equity awards commensurate with similarly situated transitioning Chief Executive Officers to which Mr. Clineburg declined. Upon completion of the leadership transition, the Committee will review Mr. Clineburg's base salary, and make adjustments that are commensurate for his role as Executive Chairman and Principal Executive Officer.

The Committee recognized Mr. Bergstrom's new responsibilities as President and Chief Executive Officer by increasing his salary to $450,000, an increase of $75,000 or 20% of his previous salary and awarded him 16,500 restricted shares and 3,000 stock options to vest ratably over three years with 33% vesting immediately and 33% vesting on the anniversary dates of the grant over the next two years.

We generally set annual base salaries for the executive officers based on the executive's experience, individual performance for the prior year and our prior year financial results. We also consider comparative salary data for the peer group identified above and believe that base salaries should be set at a level that enables us to hire and retain individuals in the banking/finance industry that can drive achievement of the Company's overall strategic business goals.

The Committee annually evaluates the performance of the Chief Executive Officer based on our financial performance, achievements in implementing our long-term strategy, and the personal observations of the Chief Executive Officer's performance by the members of the Committee and Board of Directors. During 2015, Mr. Clineburg was the Company's Chairman and Chief Executive Officer. While the Committee acknowledges the current leadership transition, they considered Mr. Clineburg's overall performance as the Chief Executive Officer as outstanding for 2015. The Committee recognized a number of key successes during 2015 when determining his overall performance; a few of which are noted below:

For other named executive officers, the Committee reviewed with Mr. Clineburg the 2015 performance evaluations for those executive officers, including pay mix of base salary, bonus and long term incentives against the peer group's average aggregate pay mix of base salary, bonus, and long term incentives. Based upon Mr. Clineburg's recommendation and current competitive positioning provided by PM, the Committee increased the salaries of Ms. Frazier by 5.3% to $395,000, Mr. Reynolds by 10.2% to $325,000, and Mr. Wendel by 4% to $260,000, effective March 2016.

See "Annual Compensation of Executive Officers" for additional information on the named executive officers' employment agreements.

We annually review the Company's performance relative to internal goals, peer performance and each executive officer's individual performance and responsibility to assess the payment of short-term incentive compensation. Financial and non-financial performance goals, and applicable metrics, are set at the beginning of each year to help guide general decision making of executives. An annual bonus target as a percent of total direct compensation is evaluated for each executive officer based on the executive's job level and competitive peer data. The Committee makes a discretionary assessment of actual financial results compared to target and the results of our peer group, and non-financial performance metrics relative to strategic objectives, safety and soundness, effectiveness in managing

risk, and community service. The Committee believes that total direct compensation for executive officers (base salary, short-term and long-term compensation) should vary based on the Company's performance and return to shareholders, and should be generally consistent relative to performance against the Company's peer group. All these considerations are taken into account in determining short-term incentive compensation for each executive officer.

While there were formal measurements and targets, the executive bonuses are awarded at the Committee's discretion and are given based upon the Committee's determination of each executive officer's contribution to our growth and profitability as well as non-financial performance metrics.

The financial measures used to evaluate 2015 corporate performance as compared to budget and the prior year were Net Income, Return on Assets, Return on Equity and Efficiency Ratio. These measures were based upon operating results which is defined as reported net income. The Committee recognizes ongoing operating results as the best means to evaluate financial performance and aligns management with the shareholder in terms of creating long term shareholder value. As shown in the table below, actual results far exceed targets and improved substantially over 2014.


Measure	2015 Target		2015 Operating Results		% of Target		2014 Operating Results (excluding M&A costs)		% Improvement over Prior Year
Net Income (in 000's)	$	40,787		$	47,334			116.05	%	38,816		21.94	%
Return on Average Assets		1.16	%		1.29	%		111.21	%	1.15	%	12.17	%
Return on Average Equity		10.42	%		11.76	%		112.86	%	10.78	%	9.09	%
Efficiency Ratio		61.00	%		56.95	%		106.64	%	62.17	%	8.40	%

Overall business results of the Company were significantly improved over 2014, including but not limited to:

In making annual bonus decisions for 2015, the Committee took into consideration the significant improvement in financial results over 2014, the strong performance versus the peer group and other non-financial factors including safety and soundness, to determine that the overall performance is near the top quartile of its peer group.

The Committee approves annually at the end of each year an overall pool of discretionary annual cash bonuses to be awarded to all officers. Certain members of the executive management team, along with the Mr. Clineburg, then allocate discretionary bonuses to officers, not including those executive officers of the Company. Mr. Clineburg then prepares and recommends to the Committee the annual

cash bonuses for certain members of executive team (other than himself) based upon actual results compared to the target results and peer group.

The Committee reviewed the Company's performance and recommendations made by Mr. Clineburg and approved an overall Officer Bonus Pool for cash bonuses for 2015 in the amount of $4,220,000. Based on its assessment of performance, the Committee approved the following short term incentive cash bonuses to be distributed from the Officer Bonus Pool to named executive officers (other than himself): $450,000 for Mr. Bergstrom; $450,000 for Ms. Frazier; $375,000 for Mr. Reynolds and $90,000 for Mr. Wendel.

With regard to Mr. Clineburg, the Committee reviewed the overall company performance as described above as well as his responsibility to assess the payment of short term incentive compensation for 2015. Furthermore, the Committee examined the competitive positioning of Mr. Clineburg's total cash compensation as it relates to the corporate performance relative to the peer group and the competitive market compensation of the peer group. After considering all of these factors, the Committee approved a short term incentive bonus of $900,000 to be distributed from the Officer Bonus Pool. Based upon information provided by PM, the Committee believes that the positioning of total cash compensation is competitive given the Company's performance.

The Committee and the Executive Chairman continue to be committed to a pay for performance philosophy, in particular as it relates to direct compensation (cash and equity awards), For example, the financial performance for 2013 was below the targets and in the bottom quartile of financial performance when compared to the peer group. According to the Executive Chairman's recommendation, the Committee did not award cash incentive bonuses to named executive officers, including him, for 2013.

Each year, the Committee also considers the desirability of granting long-term incentive awards under our 2002 Equity Compensation Plan, which was last amended as approved by shareholders in 2011 (the "Equity Plan"). The Equity Plan authorizes the granting of options, which may be incentive stock options or non-qualified stock options, stock appreciation rights, restricted stock awards, phantom stock awards or performance share awards to our directors, eligible officers and our key employees. We believe that equity ownership aligns our executives with our shareholders, promotes a long-term focus on profitability and shareholder value and is consistent with our compensation philosophy. As a result, it is our view that equity grants are an integral part of total compensation. The Committee evaluated its use of a combination of restricted stock and stock options for long-term incentive awards as opposed to only stock options as in years past. It was determined that a mix of stock options and restricted stock was consistent with trends in competitive compensation practices within the financial services industry.

In determining equity awards to the named executive officers, the Committee considers Company and individual performance, total compensation and performance relative to peers, and the role and scope of executive responsibility.

For equity awards to the executive management group, other than Mr. Clineburg, the Committee reviewed with Mr. Clineburg recommended individual awards, taking into account the respective scope of accountability and contributions of each member of the executive management team, and Company performance results for the preceding year. The Committee also reviewed total direct compensation (base salary, short term cash incentives plus equity) of the executive officers, relative to the market data of our peer group and in the context of performance compared to the same group. The Committee considers the recommendations provided for equity awards, which are then approved by the Committee and ratified by our Board of Directors.

Although awarded in calendar year 2016, the following equity awards were made to executive officers on February 16, 2016 as part of their total direct compensation package for 2015 performance: Mr. Bergstrom received a grant of options to purchase 2,000 shares of our Common Stock and 8,500 shares of restricted stock for his performance as Regional President and Chief Risk Officer of the Company. Ms. Frazier and Mr. Reynolds each received a grant of options to purchase 2,000 shares of our Common Stock and 8,500 shares of restricted stock. Mr. Wendel received a grant of options to purchase 1,000 shares of our Common Stock and 5,000 shares of restricted stock. Equity awards for 2015 performance vest ratably over three years with 33% vesting immediately and 33% vesting on the anniversary dates of the grant over the next two years.

In addition the above grants, the Committee also awarded stock options to purchase 5,000 shares of Common Stock and 35,000 shares of restricted stock to Mr. Clineburg. The equity awards vest 33% immediately and 33% vests annually on the anniversary of the grant date over the next two years. This grant of equity awards by the Committee was based, among other things, on the Company's 2015 performance, the review of his total direct compensation relative to peers, as well as the Committee's perception of his past and expected future leadership and contributions to achievement of our long-term goals. Based upon information provided by PM, the Committee deemed Mr. Clineburg's total direct compensation to be competitive given the Company's performance.

Stock options are granted with an exercise price equal to the Common Stock's fair market value at the date of grant. Based on past practices, our outstanding stock options have different vesting periods. Director stock options have ten year terms and vest and become fully exercisable at the grant date. Certain employee stock options have ten year terms and vest and become fully exercisable in 20% annual increments beginning as of the grant date. In addition, we have granted stock options to our executives that have ten year terms and with one third vesting immediately and the remaining balance vesting in one third annual increments beginning after their first year of grant.

Restricted stock awards are granted at the fair market value at the date of vesting. Like our stock option grants, our restricted stock awards may have different vesting periods similar to those described above. Currently, restricted stock awards that have been granted vest ratably over three years with 33% vesting immediately and 33% vesting on the anniversary date of the grant over the next two years for our named executive officers. For certain employee restricted stock grants, these grants vest over three years with no portion vesting immediately.

We adopted a supplemental executive retirement plan for Mr. Clineburg effective October 2005 as provided for in his employment agreement. The plan is intended to be unfunded and maintained primarily for the purpose of providing deferred compensation to Mr. Clineburg. Upon retirement, Mr. Clineburg will be entitled to an annual retirement benefit equal to $20,000 per month payable for 180 months. The benefits in the plan were fully vested on November 1, 2010 with his new employment agreement, described below in "Annual Compensation of Executive Officers." Our expense related to the plan was approximately $59,000 for 2015.

families and other dependents. This plan is also designed to provide us with a vehicle to address limitations on our contributions under any tax-qualified defined contribution plan.

Participants in the Executive Deferral Plan may elect from various investment funds, including a Company common stock fund that tracks the value of our Common Stock, for the amounts of compensation that they defer. Any of our employees who are an executive vice president or above may be eligible to participate in the Executive Deferral Plan. We provide a deemed match for each participant's contribution that does not exceed the greater of 50% of the participant's deferral or $50,000 per participant per year. This match is deemed invested in our Common Stock and vests 25% immediately and the remaining match of 75% vests over the next three years on the anniversary dates of the matching contribution.

Our executives are eligible to participate in all of our employee benefit plans, such as medical, dental, vision, group life and disability insurance and our 401(k) plan, in each case on the same basis as our other employees.

Mr. Clineburg, Mr. Bergstrom, and Mr. Reynolds receive other annual compensation for the use and maintenance of company owned automobiles and country club dues. Ms. Frazier receives other annual compensation for the use and maintenance of a company owned vehicle. We provide a company owned automobile to Mr. Clineburg, Mr. Bergstrom, Mr. Reynolds, and Ms. Frazier due to the amount of travel required as representatives of the Company. Country club memberships facilitate these executives' roles as a Company representative in the communities we serve.

Internal Revenue Code section 162(m) allows us to deduct compensation in excess of $1 million paid to our executive officers if certain criteria are satisfied. The Committee believes that grants of options and restricted stock under the Equity Plan will not qualify for the performance based compensation exception to the deductibility limit due to the lack of individual limits in the Equity Plan. Bonus awards do not meet such criteria because the Committee exercises discretion in determining awards based on such factors the Committee deems relevant as described above under "Components—Short-Term Incentive Compensation". The Committee does not, however, anticipate awarding compensation that would result in the loss of a material tax deduction.

We have reviewed our compensation policies for all of our employees to determine if they compensate or encourage our employees to take any unnecessary risk that may have a material adverse effect on our financial condition. We determined that the compensation policies we have in place are not reasonably likely to have a material adverse effect on us and do not encourage our employees to take excessive risks due to the internal controls and procedures we have in place throughout our organization. Among other things, our executive compensation program reflects the following policies and practices:

The Compensation Committee has reviewed the Compensation Discussion and Analysis included in this Proxy Statement and discussed it with our management. Based on this review and discussion, the Compensation Committee recommended that the Compensation Discussion and Analysis be included in our Annual Report on Form 10-K for the year ended December 31, 2015 and this Proxy Statement.

Such match is not to exceed $50,000 in any particular plan year and vests 25% immediately and the remainder in equal annual installments thereafter over three years from the date of the participants' contribution. In addition, during 2015 each named executive officer received grants of restricted stock, of which a portion vested immediately.

We believe the compensation for the named executive officers is representative of comparable levels within our industry. Annual cash bonuses and stock option awards are approved by the Compensation Committee and based, among other criteria, on Cardinal's overall financial performance. The Company does not specifically target to deliver a set percentage of total compensation in each individual element of pay (salary, annual incentive/bonus, long-term incentive/equity) for each of the named executive officers. The Company's compensation programs are described in detail in the Compensation Discussion and Analysis presented earlier in this proxy.

During November 2010, we entered into an employment agreement that superseded and replaced Mr. Clineburg's previous employment agreement with us. This agreement was amended on February 10, 2016 as a result of his appointment as Executive Chairman of the Company. This amendment extended the term of Mr. Clineburg's employment agreement to February 10, 2019. Thereafter, on February 10, 2019 and on each anniversary of that date, the term of the agreement will be extended for one year unless either party is notified in writing 90 days before such date. The agreement provides for his services as Executive Chairman of our Board of Directors. As Executive Chairman, Mr. Clineburg will continue to be responsible for mergers and acquisitions and strategic corporate direction. He will assist in the transition in corporate leadership of the Company and will be the liaison between the Board of Directors and other members of executive management. As such, the transitional period that was previously in Mr. Clineburg's agreement was deleted.

The amendment to Mr. Clineburg's agreement provides for reimbursement of Mr. Clineburg's legal expenses by the Company in the event his employment agreement is challenged after a change in control.

No other material changes were made to Mr. Clineburg's employment agreement. Mr. Clineburg continues to receive his existing base salary of $725,000 and is eligible to receive bonuses at the

discretion of our Board of Directors, in cash or stock, or both, and director's fees and any retainers for service on the Company's Board. Mr. Clineburg is entitled to participate in our employee benefit plans and programs for which he is or will be eligible. Mr. Clineburg remains 100% vested in all present and future benefits under his supplemental executive retirement plan and deferred income plan. The agreement continues to provide Mr. Clineburg with an automobile and will indemnify Mr. Clineburg for losses and expenses resulting from any payments or benefits from us that are found to constitute "parachute payments" under Section 280G of the Internal Revenue Code.

The agreement provides that Mr. Clineburg will receive a lump-sum severance payment if his employment is terminated without "cause" by us, for "good reason" by Mr. Clineburg, or following a "change in control" of the Company (as those terms are defined in the Agreement). If the termination is without cause or for good reason, the payment will be equal to one year salary plus the highest bonus paid during the previous five years. If Mr. Clineburg is terminated without cause or resigns within one year following a change in control, the payment will be equal to 2.99 times Mr. Clineburg's average aggregate annual compensation during the most recent five calendar years. On any termination, other than a termination for cause by us, Mr. Clineburg's unvested equity compensation will immediately vest.

The agreement contains restrictive covenants relating to the protection of confidential information, non-disclosure, non-competition and non-solicitation. The covenants not to compete or solicit continue generally for a period of 12 months following the last day of Mr. Clineburg's employment.

During 2012, the Compensation Committee amended Mr. Clineburg's agreement to limit the amount of accrued unpaid vacation leave. Mr. Clineburg is entitled to receive six weeks of vacation leave each calendar year. He may accumulate and carry over up to 40 hours of unused vacation from year to year. Any unused vacation leave in excess of 40 hours will be forfeited by Mr. Clineburg at the end of each year.

Mr. Bergstrom has an employment agreement with us, which is terminable at will by either party. The employment agreement was effective as of February 12, 2002. The employment agreement provides for a base salary, eligibility for annual performance bonus and stock option grants, and participation in our benefits plans, all of which may be adjusted by us in our discretion. In addition, his employment agreement is subject to certain restrictive covenants in the event Mr. Bergstrom voluntarily terminates his employment or is terminated for cause. Specifically, he is prohibited from rendering competing banking services in the local area and from soliciting our clients, prospective clients or employees for 12 months following the date of his termination. Mr. Bergstrom's employment agreement provides for severance payments equal to 12 months of his current base salary in the event of termination without cause and 24 months of his current base salary and continued group health and dental insurance benefits for 24 months in the event of termination without cause by us or termination by him for good reason within 12 months of a change in control. Good reason may include (1) a material diminution in Mr. Bergstrom's base compensation, authority, duties, or responsibility; (2) a change to who Mr. Bergstrom reports to directly after a change in control, if that corporate officer does not report directly to the Board of Directors of the Company or its successor; (3) a material change in geographic location; or (4) any other change to Mr. Bergstrom's employment by the Company or its successor that would constitute a material breach of the employment agreement.

In March 2010, Ms. Frazier executed an employment agreement with us. The initial term of her agreement was three years with automatic renewals for rolling one year periods not to exceed five years from the commencement date. On July 15, 2014, the Compensation Committee approved an amendment to Ms. Frazier's employment agreement with us to eliminate this provision, which would have required the term of her agreement to terminate by no later than March 30, 2015. Her agreement provides for a base salary, eligibility for annual performance bonus and stock option grants, and participation in our benefits plans, all of which may be adjusted by us in our discretion. In addition, the employment agreement is subject to certain restrictive covenants in the event she voluntarily terminates her employment or is terminated for cause. Specifically, Ms. Frazier is prohibited from rendering competing banking services in the local area and from soliciting our clients, prospective clients or employees for 12 months following the date of her termination. Her employment agreement provides for severance payments equal to 12 months of her current base salary in the event of termination without cause. In the event her employment is terminated following a change in control, her employment agreement provides for severance payments equal to 12 months of two times her current base salary (plus her current base salary for the remainder of the 12 month period following the change of control if she is terminated during that time).

F. Kevin Reynolds has an employment agreement with us which is terminable at will by either party. The employment agreement was effective as of February 12, 2002. The employment agreement provides for a base salary, eligibility for annual performance bonus and stock option grants, and participation in our benefits plans, all of which may be adjusted by us in our discretion. In addition, his employment agreement is subject to certain restrictive covenants in the event Mr. Reynolds voluntarily terminates his employment or is terminated for cause. Specifically, he is prohibited from rendering competing banking services in the local area and from soliciting our clients, prospective clients or employees for 12 months following the date of his termination. Mr. Reynolds' employment agreement provides for severance payments equal to 12 months of his current base salary in the event of termination without cause and 18 months of his current base salary in the event of his termination without cause by us or voluntary termination by him following a change in control.

Mr. Wendel does not currently have an employment agreement with us. As an officer of the Company, he receives a base salary and is eligible to participate in our annual cash bonus plan and stock option plan as determined and approved by our Compensation Committee and Board of Directors. He is eligible to participate in our deferred income plan and all other benefit plans that are generally available to our salaried employees.

See "Potential Payments Upon Termination of Employment or Change-in-Control" below for additional information regarding severance payments to our named executive officers.

We granted plan-based awards to the named executive officers in 2015. Certain executive officers received plan-based awards of stock pursuant to our deferred income plan. Grants of stock options and restricted stock disclosed in the Compensation Discussion and Analysis above that were granted during 2016 were based on each executive officer's 2015 performance.

(1): Each officer, as participants in our deferred income plan, received matches of phantom stock units in 2015. We match 50% of the contributions made by our named executive officers in our deferred income plan. Such match is not to exceed $50,000 in any particular plan year and vests 25% immediately and the remainder in equal annual installments thereafter over three years from the date of the participants' contributions. Contributions to the plan, and subsequently the match, are made to each participant's account each pay period, which is twice monthly, or a total of 24 pay periods during 2015.
(2): Each of the named executive officers received restricted stock awards during 2015 which are included in the "All Other Stock Awards" column in the table above. The grant date for the restricted stock awards to each of the named executive officers is March 18, 2015. The vesting period for each of the restricted stock grants is one-third immediately, and one-third on the subsequent anniversaries of the grant over the next two years. Grants to each of the named executive officers is as follows: Clineburg 11,500 (1,500 shares of this grant were granted to Mr. Clineburg on November 24, 2015 in his capacity as director and vested immediately); Wendel 2,000; Bergstrom 3,000; Frazier 3,000 and Reynolds 2,000.
(3): The grant date for the stock option awards granted to each of the named executive officers is March 18, 2015. These stock option awards vest one-third immediately, and one-third on the subsequent anniversaries of the grant over the next two years.

The following table presents information for those named executive officers that participate in our deferred income plan that had stock awards that vested during 2015. We also present information for those named executive officers that participate in our deferred income plan that had stock awards that vested during 2015.

The following table sets forth information as of December 31, 2015 with respect to Mr. Clineburg's participation in our supplemental executive retirement plan. No other named executive officers participate in our supplemental executive retirement plan.

The Board of Directors adopted the Cardinal Financial Corporation Supplemental Executive Retirement Plan (the "Plan"), effective October 1, 2005, for the purpose of supplementing the retirement benefits payable under our tax-qualified plans. The Plan is intended to be unfunded and maintained primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees. The Plan must be administered and construed in a manner that is consistent with that intent. The Plan is intended to satisfy the requirements of Section 409A of the Internal Revenue Code of 1986, as amended, and Treasury Regulations issued thereunder.

Upon retirement, Mr. Clineburg will be entitled to an annual retirement benefit equal to $20,000 per month payable for 180 months. Upon our change in control, Mr. Clineburg will be entitled to an additional benefit equal to $10,000 per month for a period of 180 months, commencing on the first day of the month following the change in control. If Mr. Clineburg ceases to be an eligible employee or whose employment with us is terminated with cause, he shall immediately cease to be a participant in the plan and forfeit all rights under the plan.

The following table shows the changes in the balance of the named executive officers' nonqualified deferred income plan:

We currently have in place a deferred income plan for our executive officers—the Cardinal Financial Corporation Executive Deferred Income Plan (the "Executive Deferral Plan"). The purpose of the Executive Deferral Plan is to offer participants the opportunity to defer voluntarily current compensation, including salary and annual cash bonuses, for retirement income and other significant future financial needs for themselves, their families and other dependents. This plan is also designed to provide us with a vehicle to address limitations on our contributions under any tax-qualified defined contribution plan. Participants in the Executive Deferral Plan may elect from various investment funds, including a Company Common Stock fund that tracks the value of our Common Stock, for the amounts of compensation that they defer. Any of our employees who are an executive vice president or above may be eligible to participate in the Executive Deferral Plan.

Each participant in the Executive Deferral Plan may annually elect to defer all or a portion of his or her compensation for the plan year. At a minimum, the deferral contribution cannot be less than five percent or $2,000. We provide a deemed match for each participant's contribution that does not exceed the greater of 50% of the participant's deferral or $50,000 per participant per year. This match is deemed invested in our Common Stock and vests 25% immediately and the remaining match of 75% vests over the next three years on the anniversary dates of the matching contribution. Participant's earnings in our deferred income plan are based on the performance of the participant's deemed investments they selected from the available investment options in the plan.

All distributions from the Executive Deferral Plan are made in cash, with the exception of those contributions deemed to be invested in our Common Stock, which are paid in shares of Common Stock in an amount equal to the number of whole shares of Common Stock credited to the participant's account as of the date of the distribution. Any fractional shares are paid in cash. Automatic distributions occur if the participant dies or if the participant becomes disabled. At that time, any

unvested portion of their match will vest immediately. If the participant terminates their employment with us, their vested balance will be distributed in lump sum, provided that the participant is not a key employee, in which case distribution will occur six months after their termination of service.

In the event of Mr. Clineburg's termination following a change of control, Mr. Clineburg's employment agreement with us provides for a lump-sum severance payment equal to 2.99 times his average total compensation, over the most recent five calendar year period of his employment with us prior to the termination. As of December 31, 2015, this amount was, in the aggregate, $9,405,121. Additionally, the change in control provision under his supplemental executive retirement plan vests immediately and he is entitled to begin receiving payments of $10,000 per month for 15 years, in addition to the payments he is otherwise entitled to under the plan. Mr. Clineburg's benefits upon normal retirement are discussed in "Pension Benefits" above.

In the event of termination following a change in control, Mr. Bergstrom will receive a lump-sum severance payment equal to 24 months of his base salary as of December 31, 2015, or $750,000, plus benefits continuation for 24 months following termination. Mr. Reynolds will receive a lump-sum severance payment in the event of termination following a change in control equal to 18 months of his base salary as of December 31, 2015, or $442,500. Ms. Frazier, in the event of termination following a change in control, will receive a lump-sum severance payment equal to 24 months of her base salary as of December 31, 2015, or $750,000.

Additionally, under the terms of our equity compensation plan, accelerated vesting will occur in the event of a change in control. Typically, the payments relating to stock options represent the value of the unvested and accelerated stock options, calculated by multiplying the number of accelerated options by the difference between the exercise price and the closing price of our Common Stock on the applicable date. For unvested restricted stock awards, the payments represent the value of the unvested shares multiplied by the closing price of our Common Stock on the applicable date.

At December 31, 2015, Messrs. Clineburg, Wendel, Bergstrom and Reynolds and Ms. Frazier had unvested options of 86,669, 12,751, 30,418, 17,501, and 30,418, respectively. For Mr. Clineburg, the value of the accelerated vesting of his stock options that were in the money and granted to him is $408,506 at December 31, 2015. For Mr. Wendel, the value of the accelerated vesting of his stock options that were in the money and granted to him is $51,415 at December 31, 2015. For Mr. Bergstrom, the value of the accelerated vesting of his stock options that were in the money and granted to him is $170,381 at December 31, 2015. For Ms. Frazier, the value of the accelerated vesting of her stock options that were in the money and granted to her is $170,381 at December 31, 2015. For Mr. Reynolds, the value of the accelerated vesting of his stock options that were in the money and granted to him is $83,928 at December 31, 2015.

At December 31, 2015, Messrs. Clineburg, Wendel, Bergstrom and Reynolds and Ms. Frazier had unvested restricted stock awards of 6,667, 1,334, 2,001, 1,334 and 2,001, respectively. For Mr. Clineburg, the value of the accelerated vesting of his restricted stock awards granted to him is $151,674 at December 31, 2015. For Mr. Wendel, the value of the accelerated vesting of his restricted stock awards granted to him is $30,349 at December 31, 2015. For Mr. Bergstrom, the value of the accelerated vesting of his restricted stock awards granted to him is $45,523 at December 31, 2015. For Ms. Frazier, the value of the accelerated vesting of her restricted stock awards granted to her is $45,523 at December 31, 2015. For Mr. Reynolds, the value of the accelerated vesting of his restricted stock awards granted to him is $30,349 at December 31, 2015.

In the event Mr. Clineburg is terminated without cause or good reason, his employment agreement with us provides for a lump-sum severance payment equal to one year's annual base salary plus the highest of his bonuses paid in the last five calendar years prior to the year in which he was terminated. As of December 31, 2015, this amount was $1,675,000.

If Mr. Bergstrom is terminated without cause or good reason, his employment agreement with us provides for a lump-sum severance payment equal to 12 months of his current base salary. As of December 31, 2015, this amount was $375,000.

If Mr. Reynolds is terminated without cause or good reason, his employment agreement with us provides for a lump-sum severance payment equal to 12 months of his current base salary. As of December 31, 2015, this amount was $295,000.

If Ms. Frazier is terminated without cause or good reason, her employment agreement with us provides for a lump-sum severance payment equal to 12 months of her current base salary. As of December 31, 2015, this amount was $375,000.

Under our deferred income plans, matching contributions as well as the deemed earnings upon matching contributions fully vest upon death, disability, change of control or retirement. At December 31, 2015, the unvested balances in the deferred income plan for the named executive officers are: Wendel $54,374; Bergstrom $86,784: Reynolds $67,378; and Frazier $57,241. Mr. Clineburg, as part of his employment agreement with us, is fully vested in current and future matching contributions to our deferred income plan.

The following table shows potential payments to our named executive officers under existing employment agreements, plans or arrangements for various events involving a change of control or termination of employment of each of our named executive officers, assuming a December 31, 2015 termination date, and where applicable, using the closing price of our Common Stock of $22.75 at December 31, 2015.

Some of our directors and officers are at present, as in the past, our banking customers. As such, we have had, and expect to have in the future, banking transactions in the ordinary course of our business with directors, officers, principal shareholders and their associates, on substantially the same terms, including interest rates and collateral on loans, as those prevailing at the same time for comparable transactions with persons not related to Cardinal Bank. These transactions do not involve more than the normal risk of collectibility or present other unfavorable features. The aggregate outstanding balance of loans to directors, executive officers and their associates, as a group, at December 31, 2015 totaled approximately $79.2 million, or 19.4% of the bank's equity capital at that date.

William E. Peterson, a director, is the manager and a 3.1% owner of Fairfax Corner Mixed Use, L.C. Fairfax Corner Mixed Use, L.C. owns a building in the Fairfax Corner shopping center and leases office space to George Mason Mortgage, LLC ("George Mason"). The lease commenced on July 1, 2002. We extended the lease during 2013 until June 30, 2019. The rent that George Mason pays to Fairfax Corner Mixed Use, L.C. ranges from $1.0 million to $1.2 million annually over the next four years. Common area expense reimbursements to the lessor are included in the lease. Rent payments and common area expense reimbursements totaled $1.3 million in 2015. George Mason also leases a loan origination office from a limited liability company of which Mr. Peterson is a minority owner. The rent that George Mason pays for the use of this space under existing lease arrangements ranges from $172,000 to $179,000 annually over the next three years. Rent payments totaled $149,000 in 2015.

William G. Buck, a director, has an indirect ownership in a limited liability company that owns the building where we lease branch office space for one of our locations. Certain of his immediate family members own a minority interest in the limited liability company. The rent that we pay for use of this space under the existing lease is $32,000 annually with the lease set to expire in September 2016. Rent payments under the lease totaled $32,000 in 2015.

We have not adopted a formal policy that covers the review and approval of related person transactions by our Board of Directors. The Board, however, does review all proposed related party transactions for approval. During such a review, the Board will consider, among other things, the related person's relationship to the Company, the facts and circumstances of the proposed transaction, the aggregate dollar amount of the transaction, the related person's relationship to the transaction and any other material information. Those directors that are involved in a proposed related party transaction are excused from the board and/or committee meeting during the discussion and vote of the proposal.

The Dodd-Frank Wall Street Reform and Consumer Protection Act, enacted in July 2010, requires that we provide our shareholders with the opportunity to vote to approve, on a nonbinding, advisory basis, the compensation of our named executive officers as disclosed in this proxy statement in accordance with Item 402 of the Securities and Exchange Commission's Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion.

Accordingly, we ask our shareholders to vote on the following resolution at the Annual Meeting:

The vote on this resolution is not intended to address any specific element of compensation; rather, the vote relates to the compensation of our named executive officers, as described in this proxy statement. A majority of votes cast by the holders of Shares of Common Stock is required for approval of the resolution above. However, the vote is advisory, which means that the vote is not binding on the Company, our Board of Directors or the Compensation Committee of the Board of Directors. To the extent there is any significant vote against our named executive officer compensation as disclosed in this proxy statement, the Compensation Committee will evaluate whether any actions are necessary to address the concerns of shareholders.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS VOTE FOR THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT.

The five members of the Audit Committee are independent as that term is defined in the listing standards of Nasdaq and by regulations of the SEC. The Audit Committee operates under a written charter that the Board of Directors has adopted.

Audit Fees. The aggregate amount of fees billed by KPMG LLP for professional services rendered for the audit of our annual financial statements for the fiscal years ended December 31, 2015 and 2014, and the review of the financial statements included in our Quarterly Reports on Form 10-Q for those fiscal years, were $795,000 and $565,000, respectively.

Audit-Related Fees. The aggregate amount of fees billed by KPMG LLP for professional services rendered for audit-related services was $33,000 for each of the fiscal years ended December 31, 2015 and 2014. These services included the audit of our 401(k) plan.

Tax Fees. The aggregate amount of fees billed by KPMG LLP for professional services rendered in connection with the preparation of our tax returns for each of the fiscal years ended December 31, 2015 and 2014 was $66,000 and $76,000, respectively.

All Other Fees. Additional fees billed by KPMG LLP for services not reported above for the year ended December 31, 2014 include $115,000 for the audit procedures over the Company's acquisition of United Financial Banking Companies, Inc. which occurred during 2014. There were no additional fees billed by KPMG LLP for 2015.

On January 20, 2016, the Audit Committee approved the selection of Yount, Hyde & Barbour, P.C. ("YHB") to serve as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2016. On January 22, 2016, the Company notified KPMG LLP that it had been dismissed as the Company's independent registered public accounting firm upon the completion of their audit of the Company's consolidated financial statement as of and for the year ended December 31, 2015 and the effectiveness of internal control over financial reporting as of December 31, 2015, and the issuance of their reports thereon. The decision to change the Company's independent registered public accounting firm was approved by the Company's Audit Committee.

The audit reports of KPMG LLP on the effectiveness of internal control over financial reporting as of December 31, 2015 and 2014 did not contain any adverse opinion or disclaimer of opinion, nor

were they qualified or modified as to uncertainty, audit scope, or accounting principles, except that KPMG LLP's report indicates that the Company did not maintain effective internal control over financial reporting as of December 31, 2015 and 2014 because of the effect of a material weakness on the achievement of the objectives of the control criteria and contains an explanatory paragraph that states that there was a material weakness over the Company's process to record new or modified loans into the loan sub-ledger system for the year ended December 31, 2014. For the year ended December 31, 2015, there was a material weakness over the Company's process of estimating the allowance for loan losses.

During the fiscal years ended December 31, 2015 and 2014 and the subsequent interim period through March 15, 2016, there were no: (i) disagreements with KPMG LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of KPMG LLP, would have caused KPMG LLP to make reference in connection with their opinion to the subject matter of the disagreement, or (ii) "reportable events" as described in Item 304 (a)(1)(v) of Regulation S-K, except that (a) KPMG LLP advised the Company of material weakness over the Company's process to record new or modified loans in to the sub-ledger system; (b) during the fourth quarter of 2014, management identified and remediated a material weakness in internal control over financial reporting relating to the precision of management review controls and documentation supporting the qualitative factors considered by management in the allowance for loan losses estimation process and (c) KPMG LLP advised the Company of a material weakness over the Company's process of estimating the allowance for loan losses.

KPMG LLP has furnished a letter to the SEC dated January 26, 2016 stating that it agrees with the above statements.

During the fiscal years ended December 31, 2014 and 2015 and in the interim period from January 1, 2016 through January 20, 2016, neither the Company nor anyone on its behalf consulted YHB regarding the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements, and no written report or oral advice was provided to the Company that YHB concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue. During the fiscal years ended December 31, 2014 and 2015 and in the interim period from January 1, 2016 through January 20, 2016, neither the Company nor anyone on its behalf consulted YHB regarding any matter that was the subject of a disagreement or reportable event as defined in Regulation S-K, Item 304(a)(1)(iv) and Item 304(a)(1) (v), respectively.

On January 26, 2016, the Company filed a Current Report on Form 8-K with the SEC with respect to the above referenced change in the Company's independent registered public accounting firm.

It is the policy of the Audit Committee that our independent auditor may provide only those services that have been pre-approved by the Audit Committee. Unless a type of service to be provided by the independent auditor has received general pre-approval, it requires specific pre-approval by the Audit Committee. The term of any general pre-approval is twelve months from the date of pre-approval, unless the Audit Committee or a related engagement letter specifically provides for a different period. The Audit Committee will annually review and pre-approve the services that may be provided by the independent auditor without obtaining specific pre-approval.

Requests or applications to provide services that require specific approval by the Audit Committee must be submitted to the Audit Committee by both the independent auditor and the Chief Financial Officer or Chief Accounting Officer, and must include a joint statement as to whether, in their view,

the request or application is consistent with the Securities and Exchange Commission's rules on auditor independence.

The Audit Committee is composed of five directors, each of whom is independent within the meaning of the listing standards of the Nasdaq Stock Market. The Audit Committee operates under a written charter adopted by the Board of Directors. The Audit Committee reviews its charter at least annually and revises it as necessary to ensure compliance with current regulatory requirements.

In this context, the Audit Committee has met and held discussions with management and KPMG LLP, our independent registered public accounting firm. Management represented to the Audit Committee that our consolidated financial statements for the year ended December 31, 2015 were prepared in accordance with U.S. generally accepted accounting principles. The Audit Committee has reviewed and discussed these consolidated financial statements with management and KPMG LLP, including the scope of the independent registered public accounting firm's responsibilities, critical accounting policies and practices used and significant financial reporting issues and judgments made in connection with the preparation of such financial statements.

The Audit Committee has discussed with KPMG LLP the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (AICPA Professional Standards Vol. 1, AU section 380) as adopted by the Public Company Accounting Oversight Board in Rule 3200T. The Audit Committee has also received the written disclosures and the letter from KPMG LLP relating to the independence of that firm as required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant's communications with the Audit Committee concerning independence, and has discussed with KPMG LLP the firm's independence from us. Moreover, the Audit Committee has considered whether the provision of the audit services described above is compatible with maintaining the independence of the independent auditors.

In addition, the Audit Committee has discussed with management its assessment of the effectiveness of internal control over financial reporting and has discussed with KPMG LLP its opinion as to both the effectiveness of our internal control over financial reporting and management's assessment thereof.

Based upon its discussions with management and KPMG LLP and its review of the representations of management and the report of KPMG LLP to the Audit Committee, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2015 for filing with the Securities and Exchange Commission. By recommending to the Board of Directors that the audited consolidated financial statements be so included, the Audit Committee is not opining on the accuracy, completeness or presentation of the information contained in the audited financial statements.

The Audit Committee has appointed Yount, Hyde & Barbour, P.C. ("YHB") as the Company's independent public accountant for the year ending December 31, 2016. This will be the first year for which YHB will act as the Company's independent public accountant. A representative of YHB is expected to be present at the Meeting, will have the opportunity to make a statement if he or she desires to do so and will be available to respond to appropriate questions.

The Company is not required to obtain shareholder ratification or other approval of the retention of YHB as the Company's independent public accountant. As a matter of good corporate governance, the Board of Directors is requesting that the shareholders ratify the appointment of YHB as our independent public accountant for the year ending December 31, 2016.

A majority of votes cast by the holders of shares of Common Stock is required for the ratification of the appointment of the independent auditors. If the appointment of YHB as our independent auditors is ratified, the Audit Committee may, in its discretion, change the appointment at any time during the year should it determine such a change would be in the best interest of the Company and our shareholders. If the shareholders, however, do not ratify the appointment, the Audit Committee will reconsider whether to retain YHB but may proceed with the retention of YHB if it deems it to be in the best interest of the Company and our shareholders.

THE BOARD OF DIRECTORS RECOMMENDS THAT THE SHAREHOLDERS VOTE TO RATIFY THE APPOINTMENT OF YHB AS THE COMPANY'S INDEPENDENT PUBLIC ACCOUNTANT FOR THE YEAR ENDING DECEMBER 31, 2016.

A copy of our 2015 Annual Report to Shareholders and a copy of our Annual Report on Form 10-K for the year ended December 31, 2015 has been furnished to shareholders. Additional copies may be obtained by written request to the Secretary of the Company at the address indicated below. Such documents are not part of the proxy solicitation materials.

UPON RECEIPT OF A WRITTEN REQUEST OF ANY PERSON WHO, ON THE RECORD DATE, WAS RECORD OWNER OF COMMON STOCK OR WHO REPRESENTS IN GOOD FAITH THAT HE OR SHE WAS ON SUCH DATE THE BENEFICIAL OWNER OF SUCH STOCK ENTITLED TO VOTE AT THE ANNUAL MEETING OF SHAREHOLDERS, WE WILL FURNISH TO SUCH PERSON, WITHOUT CHARGE, A COPY OF OUR ANNUAL REPORT ON FORM 10-K FOR THE FISCAL YEAR ENDED DECEMBER 31, 2015 AND THE EXHIBITS THERETO REQUIRED TO BE FILED WITH THE SEC UNDER THE SECURITIES EXCHANGE ACT OF 1934. ANY SUCH REQUEST SHOULD BE MADE IN WRITING TO JENNIFER L. DEACON, SECRETARY, CARDINAL FINANCIAL CORPORATION, AT 8270 GREENSBORO DRIVE, SUITE 500, MCLEAN, VIRGINIA 22102.

Under the regulations of the SEC, any shareholder desiring to make a proposal to be acted upon at the 2017 annual meeting of shareholders must cause such proposal to be received, in proper form, at our principal executive offices at 8270 Greensboro Drive, Suite 500, McLean, Virginia 22102, no later than November 24, 2016 in order for the proposal to be considered for inclusion in our Proxy Statement for that meeting. It is urged that any such proposals be sent by certified mail, return receipt requested.

Our Bylaws also prescribe the procedures that a shareholder must follow to nominate directors or to bring other business before shareholders' meetings. Under the Bylaws, notice of a proposed nomination or a shareholder proposal meeting certain specified requirements must be received by us not less than 60 nor more than 90 days prior to any meeting of shareholders called for the election of directors, provided in each case that, if fewer than 70 days' notice of the meeting is given to shareholders, such written notice shall be received not later than the close of the 10th day following the day on which notice of the meeting was mailed to shareholders. Assuming a date of April 21, 2017 for the 2017 annual meeting of shareholders, we must receive any notice of nomination or other business no later than February 20, 2017 and no earlier than January 21, 2017.

Our Bylaws require that the shareholder's notice set forth as to each nominee (i) the name, age, business address and residence address of such nominee, (ii) the principal occupation or employment of such nominee, (iii) the class and number of shares of the Company that are beneficially owned by such nominee, and (iv) any other information relating to such nominee that is required under federal securities laws to be disclosed in solicitations of proxies for the election of directors, or is otherwise required (including, without limitation, such nominee's written consent to being named in a proxy statement as nominee and to serving as a director if elected). Our Bylaws further require that the shareholder's notice set forth as to the shareholder giving the notice (i) the name and address of such shareholder and (ii) the class and amount of such shareholder's beneficial ownership of our capital stock. If the information supplied by the shareholder is deficient in any material aspect or if the foregoing procedure is not followed, the chairman of the annual meeting may determine that such shareholder's nomination should not be brought before the annual meeting and that such nominee shall not be eligible for election as a director of the Company. Any shareholder may obtain a copy of our Bylaws, without charge, upon written request to the Secretary of the Company.

The Board of Directors is not aware of any matters to be presented for action at the meeting other than as set forth herein. However, if any other matters properly come before the Meeting, or any adjournment thereof, the person or persons voting the proxies will vote them in accordance with their best judgment.

The Audit Committee shall consist of at least four but no more than eight directors. The members of the Audit Committee shall meet legal and regulatory independence and experience requirements, and at least one member shall have accounting or related financial expertise. The members of the Audit Committee shall be appointed by the Board of Directors and may be replaced by the Board. No member of the Audit Committee can have participated in the preparation of the Corporation's or any of its subsidiaries' financial statements at any time during the past three years.

Organization—The board of directors shall have a compensation committee composed of three or more outside directors who are independent of the management of the corporation, not employed by the organization, and are free of any relationship that would interfere with their exercise of independent judgment as a committee member. Specifically, each member of the compensation committee must be (i) "independent" in accordance with the listing requirements of the Nasdaq Stock Market, (ii) a "non-employee director" for purposes of Rule 16b-3 under the Securities Exchange Act of 1934, as amended, and (iii) an "outside director" for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended.

Statement of Policy—The compensation committee shall provide assistance to the corporate directors in fulfilling their responsibility to the shareholders, potential shareholders, and investment community to ensure that the company's officers, key executives, and board members are compensated in accordance with the company's total compensation objectives and executive compensation policy. The committee shall advise, recommend, and approve compensation policies, strategies, and pay levels necessary to support organizational objectives.

The compensation committee shall maintain free and open means of communication between the board of directors, the independent consultants, the internal human resources professionals, and the chief executive officer of the corporation.

Responsibilities—The compensation committee's policies should remain flexible to react to changing conditions and to ensure the board of directors and shareholders that: (1) the achievement of the overall goals and objectives of the corporation can be supported by adopting an appropriate executive compensation policy and implementing it through an effective total compensation program, and (2) the total compensation program and practices of the corporation are designed with full consideration of all accounting, tax, securities law, and other regulatory requirements and are of the highest quality.

The compensation committee must distinguish its oversight responsibility from involvement in the company's day-to-day management and the conduct of any independent compensation reviews. The committee must not be considered an adversary of management, rather it is part of the corporation's governance and oversight process.

The committee must work with management in accordance with its charter to demonstrate a clear relationship of pay levels to organization performance and returns to shareholders. The compensation committee will always be mindful of the fact that compensation structures not properly aligned with organizational objectives become a barrier to the organization's effectiveness in delivering sustainable returns to shareholders.

This charter shall not be construed in a manner that imposes, upon the compensation committee or its members, additional duties and responsibilities or a higher standard of conduct or care than that imposed upon directors or committees of boards of directors generally, pursuant to applicable law.
