ITEM 10. DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE

Our Directors

STEVEN E. WEST, age 52. Mr. West has served as a director of our company since December 2011 and Chairman of the Board since October 2012. Mr. West served as our Chief Executive Officer from January 1, 2009 to December 31, 2011. Since January 2011, Mr. West has been a partner at Wexford Capital LP, focusing on Wexford’s private equity energy investments.

Mr. West holds a Bachelor of Science degree in Accounting from California State University, Chico. We believe Mr. West’s background in finance, accounting and private equity energy investments, as well as his executive management skills developed as part of his career with Wexford, its portfolio companies and other financial institutions qualify him to serve on our board of directors.

TRAVIS D. STICE, age 51. Mr. Stice has served as our Chief Executive Officer since January 2012 and as a director of our company since November 2012. Prior to his current positions with us, he served as our President and Chief Operating Officer from April 2011 to January 2012.

MICHAEL P. CROSS, age 61. Mr. Cross has served as a director of our company since October 2012. Mr. Cross is President and owner of Michael P. Cross, Inc., an independent oil and natural gas producer, a position he has held since July 1994.

Business Administration. We believe that Mr. Cross’s strong oil and gas background and executive management experience qualify him for service on our board of directors.

DAVID L. HOUSTON, age 60. Mr. Houston has served as a director of our company since October 2012. Since 1991, Mr. Houston has been the principal of Houston & Associates, a firm that offers life and disability insurance, compensation and benefits plans and estate planning. Prior to 1991, Mr. Houston was President and Chief Executive Officer of Equity Bank for Savings, F.A., an Oklahoma-based savings bank and is the former chair of the Oklahoma State Ethics Commission and the Oklahoma League of Savings Institutions. In May 1992, in settlement of administrative litigation (and without any finding or admission of guilt) brought by the U.S. Office of Thrift Supervision against him in his capacity as an executive officer of a thrift institution, Mr. Houston entered into a consent order under which he agreed not to serve as an officer of, or participate in the affairs of, insured depository institutions. The order relates to alleged violations of certain lending practices in early 1990 or before. Mr. Houston served on the board of directors and executive committee of Deaconess Hospital, Oklahoma City, Oklahoma, from January 1993 until December 2008 and is the former chair of the Oklahoma State Ethics Commission and the Oklahoma League of Savings Institutions.

He is currently a Managing Member of Greyhawke Capital Advisors LLC, or Greyhawke, which he co-founded in 1998.

Mr. Plaumann holds an M.B.A. and a B.A. in Business from the University of Central Florida. We believe that Mr. Plaumann’s service on the boards of other public companies and his executive management experience, including previous experience as chairman of audit committees, qualifies him for service on our board of directors.

Investors Rights Agreement

In connection with our acquisition of oil and natural gas properties from Gulfport Energy Corporation, or Gulfport, immediately prior to the completion of our initial public offering in October 2012, we entered into an investors rights agreement with Gulfport under which Gulfport has a right, for so long as it beneficially owns more than 10% of our outstanding common stock, to designate one individual as a nominee to serve on our board of directors. Such nominee, if elected to our board of directors, will also serve on each committee of the board of directors so long as he or she satisfies the independence and other requirements for service on the applicable committee. So long as Gulfport has the right to designate a nominee to our board of directors and there is no Gulfport nominee actually serving as our director, Gulfport will have the right to appoint one individual as an advisor to the board of directors who shall be entitled to attend board and committee meetings. Mr. David Houston is Gulfport’s nominee pursuant to the investor rights agreement.

ITEM 11. EXECUTIVE COMPENSATION

As an “emerging growth company,” as defined in the Jumpstart our Business Startups Act of 2012, we are not required to include a Compensation Discussion and Analysis section and have elected to comply with the scaled disclosure requirements applicable to emerging growth companies.

Overview

This executive compensation section provides an overview of our executive compensation policy and each element of compensation that we provide.

Executive Compensation Policy

Our general compensation policy is guided by several key principles:


•	designing competitive total compensation programs to enhance our ability to attract and retain knowledgeable and experienced senior management level employees;

Table of Contents


•	motivating employees to deliver outstanding financial performance and meet or exceed general and specific business, operational and individual objectives;


•	setting compensation and incentive levels relevant to the market in which the employee provides service; and


•	providing a meaningful portion of the total compensation to our named executive officers in equity, thus assuring an alignment of interests between our senior management level employees and our stockholders.

Our compensation committee determines, subject to the terms of the employment agreements with our named executive officers, the mix of compensation, both among short-term and long-term compensation and cash and non-cash compensation, to establish structures that it believes are appropriate for each of our named executive officers. We have not retained compensation consultants to advise us on compensation matters. In making compensation decisions with respect to each element of compensation, the compensation considers numerous factors, including:


•	the individual’s particular background and circumstances, including training and prior relevant work experience;


•	the individual’s role with us and the compensation paid to similar persons at comparable companies;


•	the demand for individuals with the individual’s specific expertise and experience at the time of hire;


•	achievement of individual and company performance goals and other expectations relating to the position;


•	comparison to other executives within our company having similar levels of expertise and experience and the uniqueness of the individual’s industry skills; and


•	aligning the compensation of our executives with the performance of our company on both a short-term and long-term basis.

Executive Compensation Program Elements

The following describes each element of our executive compensation program.

Base Salary

Our named executive officers’ base salaries are determined in accordance with their respective employment agreements. Subject to applicable employment agreements, the compensation committee may increase base salaries to align such salaries with market levels for comparable positions in other companies in our industry if we identify significant market changes. Additionally, the compensation committee may adjust base salaries as warranted throughout the year for promotions or other changes in the scope or breadth of an executive’s role or responsibilities. The compensation committee may also evaluate our named executive officers’ salaries together with other components of their compensation to ensure that the executive’s total compensation is in line with our overall compensation philosophy. Pursuant to the employment agreements with the named executive officers, as amended, the base salaries of such named executive officers can be increased or decreased from time to time by the compensation committee, but not decreased below the original base salary for such executive officer. The current base salaries for Mr. Stice, Mr. Hollis and Mr. White are $400,000, $276,000, and $236,500, respectively.

Discretionary Annual Performance Bonus

In accordance with our named executive officers’ employment agreements, the board of directors will have the authority to award annual cash bonuses to our named executive officers that have achieved their respective performance goals determined by the board of directors for the applicable year. Pursuant to the terms of their respective employment agreements, the amount of the annual cash bonus that each of our named executive officers (with the exception of Mr. Stice) is eligible to receive is equal to 50% of such officer’s annual base salary. Mr. Stice is entitled to receive an annual bonus of at least 66% of his base salary and may receive an annual bonus of up to 133% of such his base salary upon the achievement of performance goals to be determined by the board of directors. Mr. Stice’s target annual bonus is 100% of his base salary upon achievement of his performance goals. We have not established any specific performance goals for our named executive officers. For 2012, the discretionary annual bonuses were paid to our named executive officers based on their respective performances and contribution to our company in 2012 and other factors generally, including our company’s performance in 2012, the value these executives bring to our company, market trends, economic climate, experience, leadership and employee retention. None of these factors was given materially greater weight than the other factors in determining the officers’ bonuses.

Table of Contents

Long Term Equity Incentive Compensation

We seek to promote an ownership culture among our executive officers in an effort to enhance our long-term performance. We believe the use of stock and stock-based awards offers the best approach to achieving our compensation goals. In connection with our initial public offering, or IPO, we adopted the Diamondback Energy, Inc. 2012 Equity Incentive Plan, or the 2012 Plan. The purpose of the 2012 Plan is to enable us, and our affiliates, to attract and retain the services of the types of employees, consultants and directors who will contribute to our long term success and to provide incentives that will be linked directly to increases in share value that will inure to the benefit of our stockholders. The 2012 Plan provides a means by which eligible recipients of awards may be given an opportunity to benefit from increases in value of our common stock through the granting of equity awards. The terms of 2012 Plan are described in more detail below.

Other Compensation and Perquisites

Consistent with our compensation philosophy, our compensation committee provides benefits to our executives that are substantially the same as those currently being offered to our other employees, including health insurance, life and disability insurance and a 401(k) plan. The benefits and perquisites that may be available to our executive officers from time to time in addition to those available to our other employees include a car allowance and club dues. A description of the 401(k) plan is below.

Employment Agreements

The following summarizes the material terms of the employment agreements we have with our named executive officers.

Travis D. Stice. Effective April 2011, we entered into an employment agreement with Mr. Stice, our Chief Executive Officer, which employment agreement was amended and restated on August 20, 2012 and further amended effective January 1, 2013. The employment agreement has a three-year term commencing as of April 18, 2011 and provides for an annual base salary that can be increased or decreased from time to time by the compensation committee, but not decreased below the original base salary of $300,000. For 2013, Mr. Stice’s salary has been set at $400,000. Mr. Stice is also entitled to receive an annual bonus of at least 66% of his base salary and may receive an annual bonus of up to 133% of such his base salary upon the achievement of performance goals to be determined by the board of directors. Mr. Stice’s target annual bonus is 100% of his base salary upon achievement of his performance goals. Mr. Stice is entitled to participate in such life and medical insurance plans and other similar plans that we establish from time to time for our executive employees, and is paid a $900 monthly vehicle allowance. Pursuant to the terms of his employment agreement, prior to the completion of the IPO, Mr. Stice had an option to acquire a 1.0% membership interest in our subsidiary Windsor Permian LLC for an aggregate exercise price of $3.6 million, subject to adjustment in the event of certain asset sales. Such option would have vested in four equal annual installments commencing on the first anniversary of the effective date of Mr. Stice’s employment agreement and would have been exercisable for five years from the effective date of his employment agreement or until his earlier termination. In connection with the completion of the IPO, this option was cancelled and replaced with the right to receive: (a) $1,000,000 in cash, of which two-thirds was payable at the time of the IPO and one-third will be payable on the first anniversary of the IPO if Mr. Stice is still employed by us or if he is terminated by us prior to that date without “cause” as defined below; (b) restricted stock units in an amount equal to $1,000,000 divided by the IPO price per share of $17.50; and (c) options to purchase 300,000 shares of our common stock at the IPO price per share of $17.50. The vesting schedule and exercise rights for these options and the restricted stock units are the same as the original option. Mr. Stice has agreed to certain restrictive covenants in his employment agreement, including, without limitation, his agreement not to compete with us, not to interfere with any of our employees, suppliers or regulators and not to solicit our customers or employees, in each case during Mr. Stice’s affiliation with us and for a period of six months thereafter. Mr. Stice’s continued employment with us is “at-will,” meaning that either we or Mr. Stice may terminate the employment relationship at any time and for any reason, with or without notice. However, if (i) we terminate Mr. Stice’s employment without “cause,” (ii) Mr. Stice resigns for good reason, meaning such resignation follows a material uncured breach by us of the employment agreement or a material diminution in Mr. Stice’s position, duties or authority, or (iii) Mr. Stice’s employment is terminated due to death or disability, then we will be obligated to continue paying Mr. Stice’s base annual salary until the expiration of the term of his employment agreement and, in the case of termination without cause or upon death or disability, to honor our obligations with respect to the option described above; provided, in each case, that Mr. Stice continues to comply with the restrictive covenants described above and (except in the case of clause (iii) above) executes a full general release in our favor. Upon his death or disability, Mr. Stice is entitled to his base salary for the remainder of the term and a prorated portion of his minimum bonus for the period prior to such event. In the event Mr. Stice’s employment is terminated for “cause,” our obligations will terminate with respect to the payment of any base salary or bonuses and the option described above effective as of the termination date. For purposes of Mr. Stice’s employment agreement, “cause” is generally defined as Mr. Stice’s (a) willful and knowing refusal or failure to perform his duties in any material

Table of Contents

respect, (b) willful misconduct or gross negligence in performing his duties, (c) material breach of his employment agreement or any other agreement with us, (d) conviction of, or a plea of guilty or nolo contendere to, a criminal act that constitutes a felony or involves fraud, dishonesty or moral turpitude, (e) indictment for a felony involving embezzlement, theft or fraud, (f) filing of a voluntary, or consent to an involuntary, bankruptcy petition, (g) dishonesty in connection with his responsibilities as an employee or (h) failure to comply with directives of our board of directors. In addition, (x) in the event that more than 50% of the combined voting power of our then outstanding stock is controlled by one or more parties that is not Wexford Capital LP or an affiliate of Wexford Capital LP or an underwriter temporarily holding securities pursuant to an offering of securities and there is a material change in Mr. Stice’s position, duties or authority or Mr. Stice is required to move outside a 50 mile radius of Midland, Texas or (y) upon termination without cause or due to death or disability, the options and restricted stock units described above will vest immediately.

Jeff White. Effective September 2011, we entered into an employment agreement with Mr. White, our Vice President—Operations, which employment agreement was amended and restated on August 20, 2012 and further amended effective January 1, 2013. The employment agreement has a three-year term and provides for an annual base salary that can be increased or decreased from time to time by the compensation committee, but not decreased below the original base salary of $220,000. For 2013, Mr. White’s base salary has been set at $236,500. Subject to Mr. White’s achievement of certain performance goals as determined by our board of directors for each fiscal year, Mr. White is entitled to an annual bonus of 50% of his annual base salary. Upon entering into the employment agreement, Mr. White received an $85,000 signing bonus and he received a $170,000 cash bonus in 2012 as a result of the IPO not having been completed within one year of his hiring. Mr. White is also entitled to participate in any life and medical insurance plans and other similar plans that we establish from time to time for our executive employees. Pursuant to the terms of his employment agreement, prior to the completion of the IPO, Mr. White had an option to acquire a 0.5% membership interest in our subsidiary Windsor Permian LLC for an aggregate exercise price of $2.5 million, subject to adjustment in the event of certain asset sales. Such option would have vested in four equal annual installments commencing on the first anniversary of the effective date of Mr. White’s employment agreement and would have been exercisable for five years from the effective date of his employment agreement or until his earlier termination (except for termination upon death, disability or by us without cause). In connection with the completion of the IPO, this option was cancelled and replaced with the right to receive: (a) $350,000 in cash; (b) restricted stock units in an amount equal to $600,000 divided by the IPO price per share of $17.50; and (c) options to purchase 100,000 shares of our common stock at the IPO price per share of $17.50. The vesting schedule and exercise rights for these options and the restricted stock units are the same as the original option. Mr. White has agreed to certain restrictive covenants in his employment agreement, including, without limitation, his agreement not to compete with us, not to interfere with any of our employees, suppliers or regulators and not to solicit our customers or employees, in each case during Mr. White’s affiliation with us and for a period of six months thereafter. Mr. White’s continued employment with us is “at-will,” meaning that either we or Mr. White may terminate the employment relationship at any time and for any reason, with or without notice. However, if (i) we terminate Mr. White’s employment without “cause,” (ii) Mr. White resigns for good reason, meaning such resignation follows a material uncured breach by us of the employment agreement or a material diminution in Mr. White’s position, duties or authority, or (iii) Mr. White’s employment is terminated due to death or disability, then we will be obligated to continue paying Mr. White’s base annual salary until the expiration of the term of his employment agreement and, in the case of termination without cause or upon death or disability, to honor our obligations with respect to the option described above; provided, in each case, that Mr. White continues to comply with the restrictive covenants described above and (except in the case of clause (iii) above) executes a full general release in our favor. In the event Mr. White’s employment is terminated for “cause,” our obligations will terminate with respect to the payment of any base salary or bonuses and the option described above effective as of the termination date. For purposes of Mr. White’s employment agreement, “cause” is generally defined as Mr. White’s (a) willful and knowing refusal or failure to perform his duties in any material respect, (b) willful misconduct or gross negligence in performing his duties, (c) material breach of his employment agreement or any other agreement with us, (d) conviction of, or a plea of guilty or nolo contendere to, a criminal act that constitutes a felony or involves fraud, dishonesty or moral turpitude, (e) indictment for a felony involving embezzlement, theft or fraud, (f) filing of a voluntary, or consent to an involuntary, bankruptcy petition, (g) dishonesty in connection with his responsibilities as an employee or (h) failure to comply with directives of our board of directors. In addition, (x) in the event that more than 50% of the combined voting power of our then outstanding stock is controlled by one or more parties that is not Wexford Capital LP, an affiliate of Wexford Capital LP or an underwriter temporarily holding securities pursuant to an offering of securities and there is either a material change in Mr. White’s position, duties or authority or Mr. White is required to move outside a 50 mile radius of Midland, Texas or (y) upon termination without cause or due to death or disability, the options and restricted stock units described above will vest immediately.

Michael Hollis. Effective September 2011, we entered into an employment agreement with Mr. Hollis, our Vice President—Drilling, which employment agreement was amended and restated on August 20, 2012 and further amended effective January 1, 2013. The employment agreement has a three-year term and provides for an annual base salary that can be increased or decreased from time to time by the compensation committee, but not decreased below the original base salary of $230,000. For 2013, Mr. Hollis’ base salary has been set at $276,000. Subject to Mr. Hollis’ achievement of certain

Table of Contents

performance goals as determined by our board of directors for each fiscal year, Mr. Hollis is entitled to an annual bonus of 50% of his annual base salary. Upon entering into the employment agreement, Mr. Hollis received a $30,000 signing bonus. Mr. Hollis is also entitled to participate in any life and medical insurance plans and other similar plans that we establish from time to time for our executive employees. Pursuant to the terms of his employment agreement, prior to the completion of the IPO, Mr. Hollis had an option to acquire a 0.5% membership interest in our subsidiary Windsor Permian LLC for an aggregate exercise price of $2.5 million, subject to adjustment in the event of certain asset sales. Such option would have vested in four equal annual installments commencing on the first anniversary of the effective date of Mr. Hollis’ employment agreement and would have been exercisable for five years from the effective date of his employment agreement or until his earlier termination (except for termination upon death, disability or by us without cause). In connection with the completion of the IPO, this option was cancelled and replaced with the right to receive: (a) $350,000 in cash; (b) restricted stock units in an amount equal to $600,000 divided by the IPO price per share of $17.50; and (c) options to purchase 100,000 shares of our common stock at the IPO price per share of $17.50. The vesting schedule and exercise rights for these options and the restricted stock units are the same as the original option. Mr. Hollis has agreed to certain restrictive covenants in his employment agreement, including, without limitation, his agreement not to compete with us, not to interfere with any of our employees, suppliers or regulators and not to solicit our customers or employees, in each case during Mr. Hollis’ affiliation with us and for a period of six months thereafter. Mr. Hollis’ continued employment with us is “at-will,” meaning that either we or Mr. Hollis may terminate the employment relationship at any time and for any reason, with or without notice. However, if (i) we terminate Mr. Hollis’ employment without “cause,” (ii) Mr. Hollis resigns for good reason, meaning such resignation follows a material uncured breach by us of the employment agreement or a material diminution in Mr. Hollis’ position, duties or authority, or (iii) Mr. Hollis’ employment is terminated due to death or disability, then we will be obligated to continue paying Mr. Hollis’ base annual salary until the expiration of the term of his employment agreement and, in the case of termination without cause or upon death or disability, to honor our obligations with respect to the option described above; provided, in each case, that Mr. Hollis continues to comply with the restrictive covenants described above and (except in the case of clause (iii) above) executes a full general release in our favor. In the event Mr. Hollis’ employment is terminated for “cause,” our obligations will terminate with respect to the payment of any base salary or bonuses and the option described above effective as of the termination date. For purposes of Mr. Hollis’ employment agreement, “cause” is generally defined as Mr. Hollis’ (a) willful and knowing refusal or failure to perform his duties in any material respect, (b) willful misconduct or gross negligence in performing his duties, (c) material breach of his employment agreement or any other agreement with us, (d) conviction of, or a plea of guilty or nolo contendere to, a criminal act that constitutes a felony or involves fraud, dishonesty or moral turpitude, (e) indictment for a felony involving embezzlement, theft or fraud, (f) filing of a voluntary, or consent to an involuntary, bankruptcy petition, (g) dishonesty in connection with his responsibilities as an employee or (h) failure to comply with directives of our board of directors. In addition, (x) in the event that more than 50% of the combined voting power of our then outstanding stock is controlled by one or more parties that is not Wexford Capital LP, an affiliate of Wexford Capital LP or an underwriter temporarily holding securities pursuant to an offering of securities and there is either a material change in Mr. Hollis’ position, duties or authority or Mr. Hollis is required to move outside a 50 mile radius of Midland, Texas or (y) upon termination without cause or due to death or disability, the options and restricted stock units described above will vest immediately.

2012 Plan

Eligible award recipients under the 2012 Plan are employees, consultants and directors of our company and its affiliates. Incentive stock options may be granted only to our employees. Awards other than incentive stock options may be granted to employees, consultants and directors. The shares that may be issued pursuant to awards consist of our authorized but unissued common stock, and the maximum aggregate amount of such common stock which may be issued upon exercise of all awards under the plan, including incentive stock options, may not exceed 2,500,000 shares, subject to adjustment to reflect certain corporate transactions or changes in our capital structure. At any time after the Company is subject to the deduction limitations under Section 162(m) of the Internal Revenue Code, the maximum number of shares of common stock issuable under our equity incentive plan to any one participant during a calendar year shall not exceed 1,000,000 shares.

Share Reserve. The aggregate number of shares of common stock initially authorized for issuance under the plan is 2,500,000 shares. However, (i) shares covered by an award that expires or otherwise terminates without having been exercised in full and (ii) shares that are forfeited to, or repurchased by, us pursuant to a forfeiture or repurchase provision under the plan may return to the plan and be available for issuance in connection with a future award.

Administration. Our board of directors (or our compensation committee or any other committee of the

board of directors as may be appointed by our board of directors from time to time) administers the plan. Among other responsibilities, the plan administrator selects participants from among the eligible individuals, determines the number of shares that will be subject to each award and determines the terms and conditions of each award, including methods of payment, vesting schedules and limitations and restrictions on awards. The plan administrator may amend, suspend, or terminate the plan at any time. Amendments will not be effective without stockholder approval if stockholder approval is

Table of Contents

required by applicable law or stock exchange requirements. Unless terminated earlier, our equity incentive plan will terminate in October 2022.

Stock Options. Incentive and nonstatutory stock options are granted pursuant to incentive and nonstatutory stock option agreements. Employees, directors and consultants may be granted nonstatutory stock options, but only employees may be granted incentive stock options. The plan administrator determines the exercise price of a stock option, provided that the exercise price of a stock option generally cannot be less than 100% (and in the case of an incentive stock option granted to a more than 10% stockholder, 110%) of the fair market value of our common stock on the date of grant, except when assuming or substituting options in limited situations such as an acquisition. Generally, options granted under the plan vest ratably over a five-year period and have a term of ten years (five years in the case of an incentive stock option granted to a more than 10% stockholder), unless specified otherwise by the plan administrator in the option agreement.

Acceptable consideration for the purchase of common stock issued upon the exercise of a stock option will be determined by the plan administrator and may include (i) cash or check, (ii) a broker-assisted cashless exercise, (iii) the tender of common stock previously owned by the optionee, (iv) stock withholding and (v) other legal consideration approved by the plan administrator, such as exercise with a full recourse promissory note (not applicable for directors and executive officers).

Unless the plan administrator provides otherwise (solely with respect to intervivos transfers to certain family members and estate planning vehicles), nonstatutory options generally are not transferable except by will or the laws of descent and distribution. An optionee may designate a beneficiary, however, who may exercise the option following the optionee’s death. Incentive stock options are not transferable except by will or the laws of descent and distribution.

Restricted Awards. Restricted awards are awards of either actual shares of common stock (e.g., restricted stock awards), or of hypothetical share units (e.g., restricted stock units) having a value equal to the fair market value of an identical number of shares of common stock, that will be settled in the form of shares of common stock upon vesting or other specified payment date, and which may provide that such restricted awards may not be sold, transferred, or otherwise disposed of for such period as the plan administrator determines. The purchase price and vesting schedule, if applicable, of restricted awards are determined by the plan administrator. A restricted stock unit is similar to a restricted stock award except that participants holding restricted stock units do not have any stockholder rights until the stock unit is settled with shares. Stock units represent an unfunded and unsecured obligation for us and a holder of a stock unit has no rights other than those of a general creditor.

Performance Awards. Performance awards entitle the recipient to vest in or acquire shares of common stock, or hypothetical share units having a value equal to the fair market value of an identical number of shares of common stock that will be settled in the form of shares of common stock upon the attainment of specified performance goals. Performance awards may be granted independent of or in connection with the granting of any other award under the plan. Performance goals will be established by the plan administrator based on one or more business criteria that apply to the plan participant, a business unit, or our company and our affiliates. Performance goals will be objective and will be intended to meet the requirements of Section 162(m) of the Internal Revenue Code. Performance goals must be determined prior to the time 25% of the service period has elapsed but not later than 90 days after the beginning of the service period. No payout will be made on a performance award granted to a named executive officer unless all applicable performance goals and service requirements are achieved. Performance awards may not be sold, assigned, transferred, pledged or otherwise encumbered and terminate upon the termination of the participant’s service to us or our affiliates.

Stock Appreciation Rights. Stock appreciation rights may be granted independent of or in tandem with the granting of any option under the plan. Stock appreciation rights are granted pursuant to stock appreciation rights agreements. The exercise price of a stock appreciation right granted independent of an option is determined by the plan administrator, but as a general rule will be no less than 100% of the fair market value of our common stock on the date of grant. The exercise price of a stock appreciation right granted in tandem with an option is the same as the exercise price of the related option. Upon the exercise of a stock appreciation right, we will pay the participant an amount equal to the product of (i) the excess of the per share fair market value of our common stock on the date of exercise over the strike price, multiplied by (ii) the number of shares of common stock with respect to which the stock appreciation right is exercised. Payment will be made in cash, delivery of stock, or a combination of cash and stock as deemed appropriate by the plan administrator.

Adjustments in capitalization. In the event that there is a specified type of change in our common stock without the receipt of consideration by us, such as pursuant to a merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction, appropriate adjustments will be made to the various limits under, and the share terms of, the plan including (i) the number and class of shares reserved under the plan, (ii) the maximum number of

Table of Contents

stock options and stock appreciation rights that can be granted to any one person in a calendar year and (iii) the number and class of shares and exercise price, strike price, or purchase price, if applicable, of all outstanding stock awards.

Corporate Transactions. In the event of a change in control transaction (other than a transaction resulting in Wexford Capital LP or an entity controlled by, or under common control with Wexford Capital LP maintaining direct or indirect control over the Company), or a corporate transaction such as a dissolution or liquidation of our company, or any corporate separation or division, including, but not limited to, a split-up, a split-off or a spin-off, or a sale in one or a series of related transactions, of all or substantially all of the assets of our company or a merger, consolidation, or reverse merger in which we are not the surviving entity, then all outstanding stock awards under the plan may be assumed, continued or substituted for by any surviving or acquiring entity (or its parent company), or may be cancelled either with or without consideration for the vested portion of the awards, all as determined by the plan administrator. In the event an award would be cancelled without consideration paid to the extent vested, the award recipient may exercise the award in full or in part for a period of ten days.

401(k) Plan

We participate in a 401(k) Plan. Employees may elect to defer a portion of their compensation up to the statutorily prescribed limit. Each pay period we make a matching contribution to each employee’s deferral, not to exceed six percent. An employee’s interests in his or her deferrals are 100% vested when contributed. An employee’s interests in the matching contribution are vested at the rate of 20% for each completed year of eligibility. The 401(k) Plan is intended to qualify under Section 401(a) of the Internal Revenue Code. As such, contributions to the 401(k) Plan and earnings on those contributions are not taxable to the employee until distributed from the 401(k) Plan, and all contributions are deductible by us when made.

Effect of Our Compensation Policies and Practices on Risk and Risk Management

The Compensation Committee reviews the risks and rewards associated with our compensation policies and programs. We believe that such policies and programs encourage and reward prudent business judgment and appropriate risk-taking over the long term. With respect to specific elements of compensation:


•	We believe that our programs balance short- and long-term incentives for our executive officers providing for an appropriate mix of fixed, discretionary and equity compensation that overall encourages long-term performance.

•

We believe that annual base salaries for our named executive officers do not encourage excessive risk-taking as they are fixed amounts that are subject to discretionary increases by our compensation committee or the board of directors upon the recommendation of our compensation committee, as the case may be, based, among other factors, on annual performance evaluations. We also believe that such annual base salaries are set at reasonable levels, as compared to the base salaries of similarly situated individuals at our peer group companies, and therefore do not encourage our named executive officers to be overly conservative with respect to taking appropriate amount of risk to increase stockholder value.

•

Our annual bonuses are designed to award achievement of short-term results. The payment and amounts of such bonuses are within the discretion of and determined by our compensation committee or the board of directors upon the recommendation of our compensation committee, as the case may be, based on the Company’s performance for the prior fiscal year and annual performance evaluations of our named executive officers.

•

Stock options and restricted stock units granted to our named executive officers are subject to time vesting provisions. We award stock options to align compensation with company performance, as the options become valuable to the executive only if the stock price increases from the date of grant. Also, stock options require a long-term commitment by executives to realize the appreciation potential of the options. We award restricted stock units to ensure that our executives have a continuing stake in the long-term success of the Company as the value of the award will depend on the stock price at and after the time of vesting. We believe that our long-term equity awards do not encourage excessive risk taking that may be associated with equity awards that vest based strictly on achieving certain targets. We also believe that our long-term equity awards provide incentive to our named executive officers to take appropriate amount of risk.


•	As described above in the discussion of the employment agreements of the named executive officers, our named executive officers are entitled to certain benefits that are payable upon the occurrence of their termination without “cause,” resignation for “good reason,” or certain change in control transactions.

Based on the foregoing, the Compensation Committee believes that the Company does not utilize compensation policies and programs creating risks that are reasonably likely to have a material adverse impact on the Company.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

Director Independence

Our board of directors has determined that David L. Houston, Michael P. Cross and Mark L. Plaumann meet the standards regarding independence set forth in the Nasdaq listing standards and are free of any relationship which, in the opinion of our board of directors, would interfere with the exercise of independent judgment in carrying out their responsibilities as directors of the Company.

Our board of directors has determined that each member of the Audit Committee is independent for purposes of serving on such committee under the Nasdaq listing standards and applicable federal law. In addition, our board of directors has determined that each current member of the Audit Committee is financially literate under the Nasdaq listing standards and that Mark L. Plaumann qualifies as the “audit committee financial expert,” as such term is defined in Item 407(d) of Regulation S-K.

Our board of directors has also determined that each member of the Compensation Committee and the Nominating Committee meets the independence requirements applicable to those committees under the Nasdaq rules. In addition, our board of directors determined that each member of our compensation committee is an “outside director” in accordance with Section 162(m) of the Internal Revenue Code and a “non-employee director” in accordance with Rule 16b-3 under the Securities Exchange Act of 1934, as amended.

Review and Approval of Related Party Transactions

Our board of directors has adopted a policy regarding related party transactions. Under the policy, the audit committee reviews and approves all relationships and transaction in which we and our directors, director nominees and executive officers and their immediate family members, as well as holders of more than 5% of any class of our voting securities and their immediate family members, have a direct or indirect material interest. The policy provides that, the following do not create a material direct or indirect interest on behalf of the related party and are therefore not related party transactions:


•	a transaction involving compensation of directors;


•	a transaction involving compensation of an executive officer or involving an employment agreement, severance arrangement, change in control provision or agreement or special supplemental benefit of an executive officer;


•	a transaction with a related party involving less than $120,000;


•	a transaction in which the interest of the related party arises solely from the ownership of a class of our equity securities and all holders of that class receive the same benefit on a pro rata basis;


•	a transaction involving indemnification payments and payments under directors and officers indemnification insurance policies made pursuant to our certificate of incorporation or bylaws or pursuant to any policy, agreement or instrument of the Company or to which the Company is bound; and

Table of Contents


•	a transaction in which the interest of the related party arises solely from indebtedness of a 5% shareholder or an “immediate family member” of a 5% shareholder.

The policy supplements the conflict of interest provisions in our Code of Business Conduct and Ethics.

Prior to the implementation of this policy and the adoption of the Code of Business Conduct and Ethics, the review and approval of related party transactions was the responsibility of our management, and all of the transactions discussed under “Related Party Transactions” below have been approved by our management, subject to a conflicts of interest policy set forth in our employee handbook, pursuant to which all of our employees must avoid any situations where their personal outside interest could conflict, or even appear to conflict, with the interests of the Company. Although our management believes that the terms of the related party transactions described below are reasonable, it is possible that we could have negotiated more favorable terms for such transactions with unrelated third parties.

Gulfport Transaction and Investor Rights Agreement

On May 7, 2012, we entered into an agreement with Gulfport Energy Corporation, or Gulfport, in which we agreed to acquire from Gulfport, prior to the effectiveness of the registration statement relating to our initial public offering, all of Gulfport’s oil and natural gas properties in the Permian Basin in exchange for (i) shares of our common stock representing 35% of our common stock outstanding immediately prior to the closing of our initial public offering and (ii) approximately $63.6 million in the form of a non-interest bearing promissory note that was repaid in full upon the closing of our initial public offering. The Gulfport transaction was completed on October 11, 2012. The aggregate consideration payable to Gulfport was subject to a post-closing cash adjustment calculated to be approximately $18.6 million and paid to Gulfport in January 2013. Under the agreement, Gulfport is generally responsible for all liabilities and obligations with respect to its Permian Basin properties arising prior to the closing of the transaction and we are responsible for such liabilities and obligations arising after the closing of the transaction. At the closing of the Gulfport transaction, we entered into an investor rights agreement with Gulfport in which Gulfport was granted certain (i) demand and “piggyback” registration rights, (ii) director nomination rights and (iii) information rights. Mr. David Houston, one of our directors, was designated by Gulfport in accordance with its director nomination rights. Mike Liddell, who served as the Operating Member and Chairman of our subsidiary Diamondback O&G LLC (formerly known as Windsor Permian LLC) prior to the completion of our IPO, is the Chairman of the Board and a director of Gulfport and has a 10% interest in DB Holdings. Charles E. Davidson, the Chairman and Chief Investment Officer of Wexford Capital, beneficially owned approximately 13.3% of Gulfport’s outstanding common stock as of December 5, 2011 and approximately 9.5% as of March 13, 2012, which interest was reduced to less than 1% as of September 28, 2012.

Administrative Services

We entered into a shared services agreement, dated March 1, 2008, with Everest Operations Management LLC (formerly, Windsor Energy Resources LLC), or Everest, an entity controlled by Wexford Capital, our equity sponsor. Under this agreement, Everest provided us with administrative and payroll services and office space in Oklahoma City, Oklahoma and we reimbursed Everest in an amount determined by Everest’s management based on estimates of the amount of office space provided and the amount of its employees’ time spent performing services for us. The reimbursement amounts were determined based upon underlying salary costs of employees performing Company related functions, payroll, revenue or headcount relative to other companies managed by Everest, or specifically identified invoices processed, depending on the nature of the cost. The initial term of the shared services agreement with Everest was two years. Since the expiration of such two-year period on March 1, 2010, the agreement, by its terms, continued on a month-to-month basis until we discontinued all services under this shared services agreement prior to the closing of our IPO. For the year ended December 31, 2012, we incurred total costs to Everest of approximately $4.4 million, and at December 31, 2012, we owed $13,000 to Everest under this shared services agreement.

Effective January 1, 2012, we entered into a shared services agreement with Everest under which we provide Everest and, at its request, certain of its affiliates with consulting, technical and administrative services, including payroll, human resources administration, accounts payable and treasury services. The initial term of this shared services agreement is two years. Upon expiration of the initial term, the agreement will continue on a month-to-month basis until cancelled by either party upon thirty days’ prior written notice. Everest, or its affiliates, reimburse us for our dedicated employee time and administrative costs based on the pro rata share of time our employees spend performing these services, including pro rata benefits and bonuses of such employees. For the year ended December 31, 2012, Everest and its affiliates reimbursed us $2.1 million for services and overhead under this shared services agreement and, at December 31, 2012, Everest and its affiliates owed us $1,000.

Windsor Permian

In connection with the completion of our IPO, we acquired all the equity interests in Diamondback O&G LLC and Windsor UT LLC from Wexford Capital in exchange for 14,697,496 shares of our common stock.

Table of Contents

Subordinated Note

Effective May 14, 2012, we issued a subordinated note to an affiliate of Wexford Capital pursuant to which, as amended, the Wexford Capital affiliate could, from time to time, advance up to an aggregate of $45.0 million. These advances were solely at the lender’s discretion and neither Wexford Capital nor any of its affiliates had any commitment or obligation to provide future capital support to us. The note bore interest at a rate equal to LIBOR plus 0.28% or 8% per annum, whichever was lower. Interest was due quarterly in arrears beginning on July 1, 2012. Interest payments were payable in kind by adding such amounts to the principal balance of this note. The unpaid principal balance and all accrued interest on the note were due and payable in full on January 31, 2015 or the earlier completion of our IPO. Any indebtedness evidenced by this note was subordinate in the right of payment to any indebtedness outstanding under our revolving credit facility. On September 30, 2012, there was $30.0 million in aggregate principal amount outstanding under this note. We repaid the outstanding borrowings under this note with a portion of the net proceeds of our IPO.

Drilling Services

Bison Drilling and Field Services LLC, or Bison, has performed drilling and field services for us under master drilling agreements and master field services agreements. These agreements are terminable by either party on 30 days’ prior written notice, although neither party will be relieved of its respective obligations arising from a drilling contract being performed prior to such termination. Bison was a wholly-owned subsidiary of Diamondback O&G LLC until March 31, 2011, when various entities controlled by Wexford Capital started contributing capital to Bison. These contributions aggregated $11.5 million and ultimately diluted Diamondback O&G LLC’s ownership interest to 52.2%. In September 2011, Diamondback O&G LLC sold a 25% interest in Bison to Gulfport for $6.0 million, subject to adjustment. At the time of the transaction, an affiliate of Wexford Capital beneficially owned approximately 13.3% of Gulfport’s common stock, but that ownership is now less than 1%. In April 2012, Gulfport increased its ownership interest in Bison to 40%. As a result of these transactions, Diamondback O&G LLC’s ownership interest in Bison was reduced to 22%, with the remaining equity interests in Bison held by Gulfport and various entities controlled by Wexford Capital. In June 2012, Diamondback O&G LLC distributed its remaining interest in Bison to its member, which are entities controlled by Wexford Capital. For the year ended December 31, 2012, we were billed $16.0 million by Bison for drilling services. We owed $120,000 to Bison as of December 31, 2012.

Midland Lease

We occupy our corporate headquarters in Midland, Texas under a five-year lease, effective May 15, 2011, with Fasken Midland, LLC, or Fasken, an entity controlled by an affiliate of Wexford Capital. During the year ended December 31, 2012, we paid $155,000 to Fasken under this lease. The current monthly rent of $11,284 under the lease will increase approximately 4% annually on June 1 of each year during the remainder of the lease term except on May 1, 2013 and June 1, 2013, our monthly rent under the lease will increase by approximately 9% and 3%, respectively. We are currently in discussions with Fasken to lease, beginning this fall, approximately 4,000 additional square feet of office space at our corporate headquarters for an initial base rent of approximately $8,000 per month.

Oklahoma City Lease

We occupy office space in Oklahoma City, Oklahoma under a sixty-seven month lease agreement, effective January 1, 2012, with Caliber Investment Group, LLC, or Caliber, an entity controlled by an affiliate of Wexford Capital. During the year ended December 31, 2012, we paid $329,000 to Caliber under this lease. Our monthly base rent will be $16,687 for the remainder of the lease term. We are also responsible for paying a portion of specified costs, fees and expenses associated with the operation of the premises. We are currently negotiating an amendment to this agreement with Caliber to lease additional square footage, which we anticipate would increase our monthly base rent by approximately $2,500.

Area of Mutual Interest and Related Agreements

Effective as of November 1, 2007, we and Gulfport entered into an area of mutual interest agreement to jointly acquire oil and gas leases in the Permian Basin. The agreement provides that each party must offer the other party the right to participate in 50% of each such acquisition. The parties also agreed, subject to certain exceptions, to share third-party costs and expenses in proportion to their respective participating interests and pay certain other fees as provided in the agreement. The agreement, which continued in force on a month-to-month basis, was terminated upon Gulfport’s contribution to us of its oil and gas properties located in the Permian Basin.

In connection with the area of mutual interest agreement, we, Gulfport and Windsor Energy Group, L.L.C., or Energy Group, an entity controlled by Wexford Capital, as the operator, entered into a joint development agreement, effective as of November 1, 2007, pursuant to which we and Gulfport agreed to develop certain jointly-held oil and gas leases in the Permian Basin and Energy Group agreed to act as the operator under the terms of a joint operating agreement, effective as of November 1, 2007. In the event either party had a majority interest in a prospect (as defined in the development agreement), the majority party could designate the operator of its choice. The parties agreed to designate Energy Group as the operator with respect to the contract area as provided in the joint operating agreement. As operator of these properties, Energy Group was responsible

Table of Contents

for the daily operations, monthly operation billings and monthly revenue disbursements for the properties in which we held an interest. Effective February 26, 2010, the agreement with Energy Group was terminated and we became the operator of these properties. Upon becoming operator effective February 26, 2010, we began providing joint interest billing services. For the year ended December 31, 2012, we billed Gulfport $46.4 million, and we billed an entity controlled by Wexford Capital $2.0 million for such services. At December 31, 2012, Gulfport owed us $0.7 million, and the Wexford Capital controlled entity owed us zero. Our joint development agreement with Gulfport was terminated in October 2012 upon Gulfport’s contribution to us of its oil and gas properties located in the Permian Basin.

Investment in Muskie Holdings LLC

During 2011, Diamondback O&G LLC purchased certain assets, real estate and rights in a lease covering land in Wisconsin that is prospective for mining oil and natural gas fracture grade sand for $4.2 million from an unrelated third party. On October 7, 2011, Diamondback O&G LLC contributed these assets, real estate and lease rights to a newly-formed entity, Muskie Holdings LLC, or Muskie, in exchange for a 48.6% equity interest. The remaining equity interests in Muskie are held 25% by Gulfport and 26.4% by entities controlled by Wexford Capital. Through additional contributions from the Wexford Capital-controlled entities to Muskie, Diamondback O&G LLC’s equity interest decreased to approximately 33%. In June 2012, Diamondback O&G LLC distributed its remaining interest in Muskie to its member, which is an entity controlled by Wexford Capital.

MidMar

We are party to a gas purchase agreement, dated May 1, 2009, as amended, with MidMar Gas LLC, or MidMar, an entity that owns a gas gathering system and processing plant in the Permian Basin. Under this agreement, MidMar is obligated to purchase from us, and we are obligated to sell to MidMar, all of the gas conforming to certain quality specifications produced from certain of our Permian Basin acreage. Following the expiration of the initial ten-year term, the agreement will continue on a year-to-year basis until terminated by either party on 30 days’ written notice. Under the gas purchase agreement, MidMar is obligated to pay us 87% of the net revenue received by MidMar for all components of our dedicated gas, including liquid hydrocarbons, and the sale of residue gas, in each case extracted, recovered or otherwise processed at MidMar’s gas processing plant, and 94.56% of the net revenue received by MidMar from the sale of such gas components and residue gas, extracted, recovered or otherwise processed at the Chevron Headlee plant. Travis D. Stice, our Chief Executive Officer, has served as a manager on MidMar’s board of managers since April 2011 and as Vice President and Secretary of MidMar since April 2012. An entity controlled by Wexford Capital in which Gulfport and certain entities controlled by Wexford Capital are members owns approximately a 28% equity interest in MidMar. The remaining equity interests in MidMar are owned by nonaffiliated third parties. For the year ended December 31, 2012, MidMar paid us $3.0 million, and at December 31, 2012, MidMar owed us $6,000 for our portion of the net proceeds from the sale of such gas products and residue gas by MidMar.

Advisory Services Agreement

During the period January 1, 2012 through October 11, 2012, Wexford Capital provided certain professional services to us, for which we were billed approximately $0.2 million. On October 11, 2012, we entered into an advisory services agreement with Wexford Capital under which Wexford Capital agreed to provide us with general financial and strategic advisory services related to our business in return for an annual fee of $500,000, plus reasonable out-of-pocket expenses. This agreement has a term of two years and will continue for additional one-year periods unless terminated in writing by either party at least ten days prior to the expiration of the then current term. The agreement may be terminated at any time by either party upon 30 days’ prior written notice. In the event we terminate the agreement, we are obligated to pay all amounts due through the remaining term of the agreement. In addition, in this agreement we have agreed to pay Wexford Capital to-be-negotiated market-based fees approved by our independent directors for such services as may be provided by Wexford Capital at our request in connection with future acquisitions and divestitures, financings or other transactions in which we may be involved. The services provided by Wexford Capital under the advisory services agreement will not extend to our day-to-day business or operations. In this agreement, we have agreed to indemnify Wexford Capital and its affiliates from any and all losses arising out of or in connection with the agreement except for losses resulting from Wexford Capital’s or its affiliates’ gross negligence or willful misconduct.

Registration Rights

We have entered into a registration rights agreement with DB Holdings and an investor rights agreement with Gulfport. Under these agreements, each of DB Holdings and Gulfport has certain demand and “piggyback” registration rights.
