BOARD OF DIRECTORS AND COMMITTEES

Board Leadership Structure

The Board does not have a formal policy addressing whether or not the roles of Chairman and Chief Executive Officer should be separate or combined. The directors serving on the Board possess considerable professional and industry experience, significant experience as directors of both public and private companies and a unique knowledge of the challenges and opportunities that the Company faces. As such, the Board believes that it is in the best position to evaluate the needs of the Company and to determine how best to organize the Company’s leadership structure to meet those needs.

At present, the Board has chosen to combine the positions of Chairman and Chief Executive Officer. While the Board believes it is important to retain the flexibility to determine whether the roles of Chairman and Chief Executive Officer should be separated or combined in one individual, the Board believes that the current Chief Executive Officer is the individual with the necessary experience, commitment and support of the other members of the Board to effectively carry out the role of Chairman.

In addition, the Board has evaluated the appropriate leadership structure for the Board and relevant corporate governance trends, and in 2014, appointed Randall M. Albert as Lead Independent Director. The responsibilities of the Lead Independent Director include acting as chair at meetings of the Board when the Chairman is not present, and preparing the agenda and presiding over executive sessions of the non-management directors of the Board.

10

The Board believes this structure promotes better alignment of strategic development and execution, more effective implementation of strategic initiatives and clearer accountability for the Company’s success or failure. Moreover, the Board believes that combining the Chairman and Chief Executive Officer positions does not impede independent oversight of the Company. Seven of the nine members of the Board are independent under NYSE rules, and the Lead Independent Director provides additional independent oversight for the Board and management.

Director Independence

Rather than adopting categorical standards, the Board assesses director independence on a case-by-case basis, in each case consistent with applicable legal requirements and the listing standards of the NYSE. After reviewing all relationships each director has with the Company, including the nature and extent of any business relationships between the Company and each director, as well as any significant charitable contributions the Company makes to organizations where its directors serve as board members or executive officers, the Board has affirmatively determined that the following directors have no material relationships with the Company and are independent as defined by the current listing standards of the NYSE: Messrs. Phillips, Zorich, Swanson, Burroughs, Albert, Paterson and Winkler. Neither Mr. Benjamin Hulburt, the Company’s Chairman, President and Chief Executive Officer, nor Mr. Christopher Hulburt, the Company’s Executive Vice President, General Counsel and Secretary, is considered by the Board to be an independent director because of their employment with the Company.

Executive Sessions

To facilitate candid discussion among the Company’s directors, the non-management directors meet in regularly scheduled executive sessions. Following his appointment as Lead Independent Director in November 2014, Mr. Randall M. Albert has presided over these meetings.

Director Nominations

Pursuant to the Company’s Corporate Governance Guidelines, the Board is responsible for identifying individuals qualified to become Board members and nominees for directorship are selected by the Board. The Board takes into account many factors, including, but not limited to, general understanding of marketing, finance and other disciplines relevant to the success of a large publicly traded company in today’s business environment; understanding of the Company’s business on a technical level; and educational and professional background. The Board evaluates each individual in the context of the Board as a whole, with the objective of recommending a group that can best support the success of the business and, based on its diversity of experience, represent stockholder interests through the exercise of sound judgment.

Although the Board is willing to consider candidates recommended by our stockholders, it has not adopted a formal policy with regard to the consideration of any director candidates recommended by our stockholders. The Board believes that a formal policy is not necessary or appropriate because of the small size of the Board and because the current Board already has a diversity of business background and industry experience. Additionally, the Board does not have a formal diversity policy in place for the director nomination process, but instead considers diversity of a candidate’s viewpoints, professional experience, education and skill set as a factor in the consideration and assessment of a candidate as set forth above.

Stockholders Agreement

In connection with the closing of our IPO,initial public offering (our “IPO”), we entered into the Stockholders Agreement with Eclipse Holdings and its limited partners, including the EnCap Funds and certain investment funds controlled by certain members of our management team (collectively, the Management Funds and Eclipse Management.“Stockholders”). The Stockholders Agreement provides that we Eclipse Holdings and its limited partnersthe Stockholders will take certain actions, such as soliciting proxies or voting shares of our common stock, to cause the Board to consist of the following

members: (i) Benjamin W. Hulburt, for so long as he remains our President and Chief Executive Officer; (ii) Christopher K. Hulburt, for so long as he remains our Executive Vice President, Secretary and General Counsel; and (iii) a number of members designated by the EnCap Funds, currently up to five, which number will be adjusted in the future based on the level of beneficial ownership of our shares of common stock by the EnCap Funds and their affiliates. For so long as the EnCap Funds and its affiliates beneficially own at least 50% of our

11

outstanding common stock, we Eclipse Holdings and its limited partnersthe Stockholders have agreed take certain actions to cause at least one of the directors designated by the EnCap Funds to be a member of each committee of the Board (subject to applicable legal requirements and stock exchange rules). In addition, we Eclipse Holdings and its limited partnersthe Stockholders have agreed to take certain actions to cause Benjamin W. Hulburt to be elected as Chairman of the Board.

Other than with respect to the election of the Board, each limited partner of Eclipse HoldingsStockholder is entitled to instruct Eclipse Holdings regarding how to vote the number of shares of our common stock held by Eclipse Holdings on the applicable voting record date that such limited partner would receive following a complete distribution on the applicable voting record date of the shares of our common stock held by Eclipse Holdings.it holds in its sole discretion.

Board’s Role in Risk Oversight

In the normal course of its business, the Company is exposed to a variety of risks, including market risks relating to changes in commodity prices, interest rates, technical risks affecting the Company’s resource base, political risks and credit and investment risk. The Board oversees the strategic direction of the Company, and in doing so considers the potential rewards and risks of the Company’s business opportunities and challenges, and monitors the development and management of risks that impact the Company’s strategic goals. The Audit Committee of the Board (the “Audit Committee”) assists the Board in fulfilling its oversight responsibilities by monitoring the effectiveness of the Company’s systems of financial reporting, auditing, internal controls and legal and regulatory compliance. The Compensation Committee assists the Board in fulfilling its oversight responsibilities by overseeing the Company’s compensation policies and practices.

Attendance at Meetings

Pursuant to the Company’s Corporate Governance Guidelines, directors are encouraged to attend the annual meetings of stockholders. The entire Board attended the Company’s 20152017 annual meeting of stockholders.

The Board held 129 meetings during 2015.2017. No director attended fewer than 75% of the meetings of the Board and of the committees of the Board on which that director served.

The Board currently has two committees: the Audit Committee and the Compensation Committee. The Audit Committee held 65 meetings and the Compensation Committee had 4 meetings during 2015.2017.

Status as a “Controlled Company”

Certain private equity funds managed by EnCap beneficially own a majority of our common stock, and as a result, we are a “controlled company” within the meaning of the NYSE’s corporate governance standards. Under the NYSE’s rules, a company of which more than 50% of the voting power is held by another person or group of persons acting together is a controlled company and may elect not to comply with certain NYSE corporate governance requirements, including the requirements that:

We are currently utilizing the exemption relating to the nominating and governance committee, and we may utilize this exemption for so long as we are a controlled company.

Committees

Audit Committee

The Audit Committee consists of Messrs. Paterson (Chair), Albert and Winkler, each of whom is independent under the rules of the SEC and the listing standards of the NYSE. As required by the rules of the SEC and listing standards of the NYSE, the Audit Committee consists solely of independent directors. The Board has also determined that each member of the Audit Committee is financially literate, and that Mr. Paterson satisfies the definition of “audit committee financial expert.”

12

The Audit Committee oversees, reviews, acts on and reports on various auditing and accounting matters to the Board, including: the selection of our independent accountants, the scope of our annual audits, fees to be paid to the independent accountants, the performance of our independent accountants and our accounting practices. In

addition, the Audit Committee oversees our compliance programs relating to legal and regulatory requirements. We have adopted an Audit Committee Charter defining the committee’s primary duties in a manner consistent with the rules of the SEC and applicable stock exchange or market standards. A copy of our Audit Committee Charter is posted on our website atwww.eclipseresources.com in the “Corporate Governance—Committee Charters”Governance” subsection under the “Investor Center” section.

Compensation Committee

Because the Company is a controlled company within the meaning of the NYSE corporate governance standards, the Company is not required to have a Compensation Committee composed entirely of independent directors. However, the Board appointed Messrs. Burroughs (Chair), Albert and Winkler to our Compensation Committee on January 20, 2015, each of whom is independent under the rules of the SEC and the listing standards of the NYSE.

Prior to January 20, 2015, all final determinations regarding executive officer compensation were made byIn 2017, the Board by analyzing the appropriateness of the base salary for each of our executive officers in light of the base salaries of other similarly situated executive officers in the peer group that we have identified, with the assistance ofCompensation Committee engaged Meridian Compensation Partners, LLC (“Meridian”), an independent compensation consultant engaged by the Board, both on a stand-alone basis and as a component of total compensation. In 2015, the Compensation Committee engaged Meridian to review our compensation arrangements for our executive officers and independent directors, including an analysis of both the competitive market and the design of the compensation arrangements. As part of its reports to the Compensation Committee, Meridian evaluated the compensation arrangements of our peer companies and provided competitive compensation data and analysis relating to the compensation of our executive officers and independent directors.

The Compensation Committee reviews, evaluates and approves the agreements, plans, policies and programs of the Company to compensate the Company’s executive officers and directors. The Compensation Committee’s goal is to ensure that the Company’s compensation programs are designed to provide a competitive level of compensation to attract and retain talented directors and executives, reward and encourage maximum corporate and individual performance, promote accountability and assure that employees and director interests are aligned with the interests of the Company’s stockholders. Pursuant to its charter, the Compensation Committee may delegate to its Chairman, any one of its members or any subcommittee it may form, the responsibility and authority for any particular matter, as it deems appropriate from time-to-time under the circumstances.  To the extent necessary, the Compensation Committee or the Board may delegate the approval of award grants and other transactions and responsibilities regarding the administration of compensatory programs to a subcommittee consisting solely of members of the Compensation Committee who are (a) “Non-Employee Directors” for purposes of Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and/or (b) “outside directors” within the meaning of Section 162(m) of the Internal Revenue Code of 1986 in effect as of November 1, 2017.

Nominating & Governance Committee

Pursuant to our corporate reorganization, the Series C-1 Units and Series C-2 Units were exchanged for Series C-1 Units and Series C-2 Units in Eclipse Holdings, and such Incentive Units are held by Eclipse Management, L.P. (“Eclipse Management”), a limited partner of Eclipse Holdings of which management members holding Series C-1 and Series C-2 units are partners. Holders of Incentive Units have economic rights as limited partners of Eclipse Management that approximate the economic rights such holders had when directly holding their Incentive Units. Holders of Incentive Units participate in distributions from Eclipse Holdings through Eclipse Management after distributions have been made to the EnCap Funds, with the level of participation in such distributions adjusting upwards if such distributions satisfy additional specified hurdle rates and return on investment factors. Through Eclipse Management, holders of Series C-2 units participate in distributions from Eclipse Holdings after holders of Series C-1 units have received specified cash distributions. The Incentive Units vest on varying schedules as determined by the vesting schedule set forth in each grant agreement (generally in equal annual amounts over a set period of time or upon a sale of Eclipse).

Our management’s indirect ownership of limited partner interests in Eclipse Holdings provides our management with a strong incentive to continue to grow the value of our company. Specifically, the level of participation of Eclipse Management in the distributions from Eclipse Holdings adjusts following any “payout,” which occurs when: (i) the aggregate distributions to the EnCap Funds, when discounted at the applicable hurdle rate from the respective dates of such distributions to January 31, 2011, equal the aggregate capital contributions of the EnCap Funds, when discounted at the applicable hurdle rate from the respective dates of such capital contributions to January 31, 2011; and (ii) the aggregate distributions that the EnCap Funds have received equal or exceed the product of the applicable return on investment factor and the aggregate capital contributions made by the EnCap Funds. Eclipse Management will: (i) participate in 12.07% of distributions following the first payout (i.e., a payout using a hurdle rate of 8% per annum compounded monthly and a return on investment factor of 1.10); (ii) participate in 22.42% of distributions following the second payout (i.e., a payout using a hurdle rate of 20% per annum compounded monthly and a return on investment factor of 1.75); and (iii) participate in 27.59% of distributions following the third payout (i.e., a payout using a hurdle rate of 30% per annum compounded monthly and a return on investment factor of 2.50).

Distributions from Eclipse Holdings to Eclipse Management (and therefore indirectly to the former holders of Incentive Units) are made from the assets of Eclipse Holdings through either (i) an in-kind distribution of our common stock held by Eclipse Holdings, or (ii) a cash distribution generated by the sale of such common stock at the discretion of the board of Eclipse Holdings. Compensation expense for the Incentive Units is calculated based on the fair value of the award at the date of grant and is recognized over the requisite service period. Such charges to stock compensation expense for awards that continue to vest subsequent to our corporate reorganization are recorded by us and credited to additional paid-in capital. If the vesting of the Incentive Units is accelerated through a sale or transfer of all or substantially all of our common stock or assets, any unrecognized compensation cost will be recorded at that time.

In 2013, Mr. DeNezza was granted Incentive Units in connection with the commencement of his employment with us. The Incentive Units issued to Mr. DeNezza in 2013 are subject to vesting, with one-third of each class of the Incentive Units vesting on each anniversary of his hire date. The first two-thirds of each class of Incentive Units vested in fiscal 2015, and one-third remains unvested, though the vesting may accelerate upon the earlier of a sale or transfer of substantially all of the interests or assets of Eclipse, including by way of a merger.

Additional Narrative Disclosure

Retirement Benefits

We currently maintain a retirement plan intended to provide benefits under section 401(k) of the Internal Revenue Code of 1986, as amended, under which employees, including our Named Executive Officers, are allowed to contribute portions of their compensation to a tax-qualified retirement account. Under our 401(k) plan, we provide matching contributions equal to 100% of the first 6% of employees’ eligible compensation contributed to the plan.

Employment, Severance or Change in Control Agreements

As disclosed above under “—Employment Agreements,” in August 20142017 we entered into amended and restated employment agreements with each of our Named Executive Officers. The employment agreements provide each Named Executive Officer with certain severance benefits upon termination. If the Named Executive Officer’s employment is terminated by us “without Cause” or by the Named Executive Officer for “Good Reason” (as such terms are defined in the employment agreements), then:

18

If the Named Executive Officer’s employment is terminated upon the Named Executive Officer’s death or “Disability” (as defined in the employment agreements), then we will make a lump sum payment to the Named Executive Officer equal to one times the Named Executive Officer’s annual base salary as of the termination date and we will provide the Named Executive Officer with the Post-Employment Health Coverage.

In September 2015, the Compensation Committee approved the Eclipse Resources Corporation Change in Control Severance Policy (the “Change in Control Policy”). The Change in Control Policy became effective on September 11, 2015 and, unless renewed by the Board, will expire on the first anniversary of such date. The Change in Control Policy covers certain senior employees of the Company (each, a “Participant,” and collectively, the “Participants”), including the Named Executive Officers, and provides for cash payments and other benefits in the event of a “Qualifying Termination” (as defined in the Change in Control Policy) that occurs during the period (the “Change in Control Protection Period”) beginning six months before and ending 24 months after a “Change in Control” (as defined in the Change in Control Policy).

Under the Change in Control Policy, if a Qualifying Termination occurs during the Change in Control Protection Period, the Named Executive Officers will be entitled to receive the Named Executive Officer’s “Annual Cash Bonus Amount” (as defined in the Change in Control Policy) and three times the sum of the Named Executive Officer’s “Base Salary” (as defined in the Change in Control Policy) and “Target Bonus Amount” (as defined in the Change in Control Policy).

In addition, Participants will be eligible to receive reimbursements from the Company for amounts necessary to continue the health care coverage under the Company’s group health plans for the Participant and the Participant’s eligible dependents for a period of up to 18 months following a Qualifying Termination. Further, the cash payment due under the Change in Control Policy to a Named Executive Officer will be reduced by the amount of cash payments, if any, provided under the terms of an individually negotiated agreement, including the employment agreements described above, in effect on the date of such Named Executive Officer’s termination that relates to severance benefits. Cash payments and other benefits under the Change in Control Policy are subject to the Participant’s execution of a Separation and Release Agreement releasing the Company from claims by such Participant.

Because ofDuring 2017, under the additional activity and time responsibility of our committee chairs and Lead Independent Director, the Compensation Committee and Board approved an amended and restated director compensation program on May 11, 2015 (the “Amended Director Compensation Program”).

ITEM TWO: RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee has selected Grant Thornton LLP as the independent registered public accounting firm of the Company for the year ending December 31, 2016.2018. Grant Thornton LLP has audited the Company’s and its predecessor’s financial statements since 2011. The audit of the Company’s annual consolidated financial statements for the year ended December 31, 20152017 was completed by Grant Thornton LLP on March 3, 2016.2, 2018.

The Board is submitting the selection of Grant Thornton LLP for ratification at the Annual Meeting. The submission of this matter for ratification by stockholders is not legally required, but the Board and the Audit Committee believe the submission provides an opportunity for stockholders through their vote to communicate with the Board and the Audit Committee about an important aspect of corporate governance. If the stockholders do not ratify the selection of Grant Thornton LLP, the Audit Committee will reconsider, but will not be required to rescind, the selection of that firm as the Company’s independent registered public accounting firm. Representatives of Grant Thornton LLP are expected to be present at the Annual Meeting and will have the opportunity to make a statement if they desire to do so. Such representatives are also expected to be available to respond to appropriate questions.

The Audit Committee has the authority and responsibility to retain, evaluate and replace the Company’s independent registered public accounting firm. The stockholders’ ratification of the appointment of Grant Thornton LLP does not limit the authority of the Audit Committee to change the Company’s independent registered public accounting firm at any time.

THE BOARD UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS VOTE “FOR” THE RATIFICATION OF THE SELECTION OF GRANT THORNTON LLP AS THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM OF THE COMPANY FOR THE YEAR ENDING DECEMBER 31, 2016.2018.

AUDIT MATTERS

The material in this report is not “soliciting material,” is not deemed “filed” with the SEC, and is not to be incorporated by reference into any filing under the Securities Act of 1933, as amended or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in such filing.

Audit Committee Report

Pursuant to its charter, the Audit Committee’s principal functions include the duty to: (i) oversee the appointment, compensation, retention and oversight of the work of the independent auditors hired for the purpose of

21

issuing an audit report or performing other audit, review or attest services for the Company; (ii) pre-approve audit or non-audit services proposed to be rendered by the Company’s independent registered public accounting firm; (iii) annually review the qualifications and independence of the independent registered public accounting

firm’s senior personnel that are providing services to the Company; (iv) review with management and the independent registered public accounting firm the Company’s annual and quarterly financial statements, earnings press releases and financial information and earnings guidance provided to analysts and ratings agencies; (v) oversee the Company’s internal audit; (vi) ratify related party transactions as set forth in the Company’s Related Persons Transactions Policy; (vii) review with management the Company’s major financial risk exposures;exposures; (viii) assist the Board in monitoring compliance with legal and regulatory requirements; (ix) prepare the report of the Audit Committee for inclusion in the Company’s proxy statement; and (x) annually review and reassess its performance and the adequacy of its charter.

While the Audit Committee has the responsibilities and powers set forth in its charter, and the Company’s management and the independent registered public accounting firm are accountable to the Audit Committee, it is not the duty of the Audit Committee to plan or conduct audits or to determine that the Company’s financial statements and disclosures are complete and accurate and are in accordance with generally accepted accounting principles and applicable laws, rules and regulations.

In performing its oversight role, the Audit Committee has reviewed and discussed the Company’s audited financial statements with the Company’s management and independent registered public accounting firm. The Audit Committee has also discussed with the independent registered public accounting firm the matters required to be discussed by the Public Company Accounting Oversight Board Auditing Standard No. 16,1301, Communications with Audit Committees. The Audit Committee has received the written disclosures and the written statement from the independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence. The Audit Committee has also considered whether the provision of non-audit services by the independent registered public accounting firm to the Company is compatible with maintaining the independent registered public accounting firm’s independence and has discussed with the independent registered public accounting firm its independence.

Based on the reviews and discussions described in this Audit Committee Report, and subject to the limitations on the roles and responsibilities of the Audit Committee referred to herein and in its charter, the Audit Committee recommended to the Board that the Company’s audited financial statements for the year ended December 31, 20152017 be included in the Form 10-K, which was filed with the SEC on March 4, 2016.2, 2018. The Audit Committee also selected Grant Thornton LLP as the Company’s independent registered public accounting firm for the year ending December 31, 2016.2018.

Members of the Audit Committee rely, without independent verification, on the information provided to them and on the representations made by the Company’s management and independent registered public accounting firm. Accordingly, the Audit Committee’s oversight does not provide an independent basis to determine that management has maintained appropriate accounting and financial reporting principles or appropriate internal controls and procedures designed to assure compliance with accounting standards and applicable laws and regulations. Furthermore, the Audit Committee’s considerations and discussions referred to above do not assure that (i) the audit of the Company’s financial statements has been carried out in accordance with generally accepted auditing standards, (ii) the Company’s financial statements are presented in accordance with generally accepted accounting principles, or (iii) Grant Thornton LLP is in fact independent.

Members of the Audit Committee:

Richard D. Paterson (Chairman)

Randall M. Albert

Joseph C. Winkler, III

Audit and Other Fees

The table below sets forth the aggregate fees and expenses billed by Grant Thornton LLP, the Company’s independent registered public accounting firm, for the last two fiscal years to the Company and its predecessor, Eclipse I:Company:

(1) Includes professional services for the audit of our annual financial statements, reviews of the financial statements included in our Form 10-Q filings, and services that are normally provided in connection with statutory and regulatory filings or engagements.

(2) Includes fees associated with assurance and related services that are reasonably related to the performance of the audit or review of our financial statements. This category includes fees related to consulting services.

(3) Includes fees associated with tax compliance, tax advice and tax planning.

The Audit Committee has considered whether the provision of the above services other than audit services is compatible with maintaining Grant Thornton LLP’s independence and has concluded that it is consistent.

The Audit Committee has the sole authority to appoint or replace the independent auditor and is directly responsible for the compensation and oversight of the work of the independent auditor. The Audit Committee is responsible for the engagement of the independent auditor to provide permissible non-audit services, which require pre-approval by the Audit Committee (other than with respect tode minimis exceptions described in the rules of the NYSE or the SEC that are approved by the Audit Committee). The Audit Committee ensures that approval of non-audit services by the independent auditor are disclosed to investors in periodic reports filed with the SEC.

ITEM THREE: OTHER BUSINESS

The Board knows of no other business to be brought before the Annual Meeting. If, however, any other business should properly come before the Annual Meeting, the persons named in the accompanying form of proxy will vote the proxy in their discretion as they may deem appropriate, unless the proxy directs otherwise.
