SEPARATION AGREEMENT AND RELEASE

Exhibit 10.9

SEPARATION AGREEMENT AND RELEASE

This Separation Agreement and Release (“Agreement”) is entered into by Matador Resources Company, a Texas corporation (“Matador” or “the Company”), and Wade I. Massad (“Employee”) as of August 10, 2012 (the “Agreement Date”). Matador and Employee are referred to as the “Parties.” This Agreement cancels and supersedes all prior agreements relating to Employee’s employment with Matador, including the Nonqualified Stock Option Agreement by and between Matador and Employee dated February 1, 2012 (the “Stock Option Agreement”) except as provided in this Agreement.

WHEREAS, Matador and Employee entered into an Employment Agreement as of December 1, 2011 (the “Employment Agreement”). This Agreement is entered into by and between Employee and Matador pursuant to the Employment Agreement;

WHEREAS, because of Employee’s employment as an employee of Matador, Employee has obtained intimate, proprietary and unique knowledge of all aspects of Matador’s business operations, current and future plans, financial plans and other confidential and proprietary information;

WHEREAS, Employee’s employment with Matador and all other positions, if any, held by Employee in Matador or any of its subsidiaries or affiliates, including officer positions, terminated effective as of July 31, 2012 (the “Separation Date”);

WHEREAS, following the Separation Date and based upon the contributions Employee has made to Matador, Matador and Employee intend to enter into an arrangement whereby Employee will provide certain services to Matador on a consulting basis;

WHEREAS, except as otherwise provided herein, the Parties desire to finally, fully and completely resolve all matters that now or may exist between them, including, but not limited to those concerning the Employment Agreement (except for the post-termination obligations contained in the Employment Agreement), Employee’s job performance and activities while employed by Matador and Employee’s hiring, employment and separation from Matador, and all matters related to benefits and compensation connected with such employment;

NOW, THEREFORE, in consideration of the premises and mutual covenants and agreements hereinafter set forth, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto agree as follows:

1. End of Employee’s Employment. Employee’s employment with Matador terminated on the Separation Date.

2. Certain Payments and Benefits.

(a) Accrued Obligations. In accordance with Matador’s customary payroll practices, Matador shall pay Employee for all unpaid salary, unreimbursed business expenses, and any accrued but unused vacation through the Separation Date (“Accrued Obligations”).

1

(b) Payments. Subject to Employee’s consent to and fulfillment of Employee’s obligations in this Agreement and Employee’s post termination obligations in the Employment Agreement, provided that Employee does not revoke this Agreement pursuant to Section 12 hereof, Matador shall pay Employee the amount of $60,000, minus normal payroll withholdings and taxes, (“Bonus Payment”), payable in a lump sum payment. The Bonus Payment will not be treated as compensation under Matador’s 401(k) Plan or any other retirement plan. If Employee is eligible for and timely elects continuation coverage under Matador’s group health plan in accordance with the Consolidated Omnibus Reconciliation Act of 1985, as amended (“COBRA”), Matador agrees to pay the entire cost of the premiums for such coverage for Employee and his eligible dependents for the period of coverage beginning on July 31, 2012 and ending on the earliest of (i) December 31, 2012, (ii) the date that Employee obtains full-time employment with another employer or dies or (iii) the date Employee’s coverage under Matador’s health plan terminates for any reason (other than non-payment of premiums). Matador shall be under no obligation to pay the cost of such premiums if such payment subjects Matador to any penalty, excise or other tax associated with such payment or coverage. If Employee is eligible for additional COBRA continuation coverage after the expiration of the period set forth herein, Employee may continue such coverage, provided Employee shall be solely responsible for the payment of any premiums for such COBRA continuation coverage. Matador shall provide Employee under separate cover at his home address, information necessary and required by law regarding the COBRA election. Benefits provided under this Section 2(b) to Employee or his eligible dependents shall be modified to the extent benefits under an applicable plan are modified for active employees of Matador.

(c) Waiver of Additional Compensation or Benefits. Other than the compensation and payments provided for in this Agreement and the post-termination benefits provided for in this Agreement and in the Employment Agreement, Employee shall not be entitled to any additional compensation, benefits, payments or grants under any agreement, benefit plan, severance plan or bonus or incentive program established by Matador or any of Matador’s affiliates, including, but not limited to the Stock Option Agreement, other than any vested retirement plan benefit or any vested equity grants. Employee agrees that the release in Paragraph 3 covers any claims Employee might have regarding Employee’s compensation, bonuses, stock options or grants and any other benefits Employee may or may not have received during Employee’s employment with Matador.

3. General Release and Waiver. In consideration of the payments and other consideration provided for in this Agreement, that being good and valuable consideration, the receipt, adequacy and sufficiency of which are acknowledged by Employee, Employee, on Employee’s own behalf and on behalf of Employee’s agents, administrators, representatives, executors, successors, heirs, devisees and assigns (collectively, the “Releasing Parties”) hereby fully releases, remises, acquits and forever discharges Matador and all of its affiliates, and each of their respective past, present and future officers, directors, shareholders, equity holders, members, partners, agents, employees, consultants, independent contractors, attorneys, advisers, successors and assigns (collectively, the “Released Parties”), jointly and severally, from any and all claims, rights, demands, debts, obligations, losses, causes of action, suits, controversies, setoffs, affirmative defenses, counterclaims, third party actions, damages, penalties, costs, expenses, attorneys’ fees, liabilities and indemnities of any kind or nature whatsoever (collectively, the “Claims”), whether known or unknown, suspected or unsuspected, accrued or unaccrued, whether at law, equity, administrative, statutory or otherwise, and whether for injunctive relief, back pay, fringe benefits,

2

reinstatement, reemployment, or compensatory, punitive or any other kind of damages, which any of the Releasing Parties ever have had in the past or presently have against the Released Parties, and each of them, arising from or relating to Employee’s employment with Matador or its affiliates or the termination of that employment or any circumstances related thereto, or (except as otherwise provided below) any other matter, cause or thing whatsoever, including without limitation all claims arising under or relating to employment, employment contracts, employee benefits or purported employment discrimination or violations of civil rights of whatever kind or nature, including without limitation all claims arising under the Age Discrimination in Employment Act (“ADEA”), the Americans with Disabilities Act as amended, the Family and Medical Leave Act of 1993, the Equal Pay Act of 1963, the Rehabilitation Act of 1973, Title VII of the United States Civil Rights Act of 1964, 42 U.S.C. § 1981, the Fair Labor Standards Act, the Employee Retirement Income Security Act, the Civil Rights Act of 1991, the Civil Rights Acts of 1866 and/or 1871, the Sarbanes-Oxley Act, the Genetic Information Nondiscrimination Act, the Lily Ledbetter Act, the Texas Commission on Human Rights Act, the Texas Payday Law, the Texas Labor Code or any other applicable federal, state or local employment statute, law or ordinance, including, without limitation, any disability claims under any such laws, claims for wrongful discharge, claims arising under state law, contract claims including breach of express or implied contract, alleged tortious conduct, claims relating to alleged fraud, breach of fiduciary duty or reliance, breach of implied covenant of good faith and fair dealing, and any other claims arising under state or federal law, as well as any expenses, costs or attorneys’ fees. Employee further agrees that Employee will not file or permit to be filed on Employee’s behalf any such claim. Notwithstanding the preceding sentence or any other provision of this Agreement, this release is not intended to interfere with Employee’s right to file a charge with the Equal Employment Opportunity Commission (the “EEOC”), or other comparable agency, in connection with any claim Employee believes Employee may have against Matador or its affiliates. However, by executing this Agreement, Employee hereby waives the right to recover in any proceeding Employee may bring before the EEOC or any state human rights commission or in any proceeding brought by the EEOC or any state human rights commission on Employee’s behalf. This release shall not apply to any of Matador’s obligations under this Agreement or post-termination obligations under the Employment Agreement, any vested retirement plan, benefits, any vested equity grants or COBRA continuation coverage benefits. Employee acknowledges that certain of the payments and benefits provided for in Section 2 of this Agreement constitute good and valuable consideration for the release contained in this Section 3.

4. Return of Matador Property. Employee may retain all equipment, records, files, programs or other materials and property in Employee’s possession which belong to Matador or any of its affiliates that are required for any services to be provided by Employee to Matador following the Separation Date on a consulting basis; however, at any time Matador may request a return of all such items and Employee shall promptly return such items to Matador.

5. Non-Disparagement. Employee agrees that Employee will not, directly or indirectly, disclose, communicate, or publish any disparaging information concerning Matador or the Released Parties, or cause others to disclose, communicate, or publish any disparaging information concerning the same. Matador, on its own behalf and on behalf of its officers and directors, agrees that they will not, directly or indirectly, disclose, communicate or publish any disparaging information concerning Employee, or cause others to disclose, communicate, or publish any disparaging information concerning Employee.

6. Change in Relationship. Nothing in this Agreement shall be construed in any way as an admission by either Party of any acts of wrongdoing, violation of any statute, law or legal or contractual right. Employee represents to Matador that he has faithfully fulfilled his duties under the Employment Agreement to date and both parties intend to enter into an arrangement whereby Employee will provide certain services to Matador on a consulting basis.

7. Voluntary Execution of the Agreement. Employee and Matador represent and agree that they have had an opportunity to review all aspects of this Agreement, and that they fully understand all the provisions of the Agreement and are voluntarily entering into this Separation Agreement and Release. Employee further represents that Employee has not transferred or assigned to any person or entity any claim involving Matador or any portion thereof or interest therein.

8. Ongoing Obligations. Employee reaffirms and understands Employee’s ongoing obligations in the Employment Agreement, including Sections 8, 9, 10, 11 and 21.

9. Binding Effect. This Agreement shall be binding upon Matador and upon Employee and Employee’s heirs, administrators, representatives, executors, successors and assigns and Matador’s representatives. In the event of Employee’s death, this Agreement shall operate in favor of Employee’s estate and all payments, obligations and consideration will continue to be performed in favor of Employee’s estate.

10. Severability. Should any provision of this Agreement be declared or determined to be illegal or invalid by any government agency or court of competent jurisdiction, the validity of the remaining parts, terms or provisions of this Agreement shall not be affected and such provisions shall remain in full force and effect.

11. Entire Agreement. Except for the post-termination obligations in the Employment Agreement, any vested retirement plan benefits and any vested equity grant agreements, this Agreement sets forth the entire agreement between the parties, and fully supersedes any and all prior agreements, understandings, or representations between the parties pertaining to Employee’s employment with Matador, the subject matter of this Agreement or any other term or condition of the employment relationship between Matador and Employee. Employee represents and acknowledges that in executing this Agreement, Employee does not rely, and has not relied, upon any representation(s) by Matador or its agents except as expressly contained in this Agreement or the Employment Agreement. Employee and Matador agree that they have each used their own judgment in entering into this Agreement.

12. Knowing and Voluntary Waiver. Employee, by Employee’s free and voluntary act of signing below, (i) acknowledges that Employee received this Agreement on July 24, 2012 and has been given a period of twenty-one (21) days to consider whether to agree to the terms contained herein, (ii) acknowledges that Employee has been advised to consult with an attorney prior to executing this Agreement, (iii) acknowledges that Employee understands that this Agreement specifically releases and waives all rights and claims Employee may have under the ADEA prior to the date on which Employee signs this Agreement, and (iv) agrees to all of the terms of this Agreement and intends to be legally bound thereby. The Parties acknowledge and agree that each Party has reviewed and negotiated the terms and provisions of this Agreement and has contributed to

its preparation (with advice of counsel). Accordingly, the rule of construction to the effect that ambiguities are resolved against the drafting party shall not be employed in the interpretation of this Agreement. Rather, the terms of this Agreement shall be construed fairly as to both Parties and not in favor of or against either Party, regardless of which Party generally was responsible for the preparation of this Agreement.

This Agreement will become effective, enforceable and irrevocable on the eighth day after the date on which it is executed by Employee (the “Effective Date”). During the seven-day period prior to the Effective Date, Employee may revoke Employee’s agreement to accept the terms hereof by giving notice to Matador of Employee’s intention to revoke. If Employee exercises Employee’s right to revoke hereunder, Employee shall not be entitled, except as required by applicable wage payment laws, including, but not limited to, Accrued Obligations, to any payment hereunder until Employee executes and does not revoke a comparable release of claims, and to the extent such payments or benefits have already been made, Employee agrees that Employee will immediately reimburse Matador for the amounts of such payments and benefits to which he is not entitled.

13. Notices. All notices and other communications hereunder will be in writing. Any notice or other communication hereunder shall be deemed duly given if it is delivered personally or sent by registered or certified mail, return receipt requested, postage prepaid, and addressed to the intended recipient as set forth:
