 REGIONS EQUIPMENT FINANCE 
 CONTINUING GUARANTY AGREEMENT 
 (the “Guaranty”)

 COMPANIES: TX ENERGY SERVICES, LLC AND C.C. FORBES, LLC 

MASTER AGREEMENT 
 DATED: JUNE 6, 2012 (the “Master Agreement”) 
 WHEREAS, the
undersigned (hereinafter referred to as the “Guarantor”) has agreed to guarantee the payment of all credit heretofore or hereafter extended and all advances heretofore or hereafter made by Regions Equipment Finance Corporation
(“REFCO”) and/or Regions Commercial Equipment Finance, LLC (“RCEF”) to TX ENERGY SERVICES, LLC and C.C. FORBES, LLC (hereinafter referred to individually as a “Company” and
collectively as the “Companies”), and of all other Liabilities (as hereinafter defined) of the Company to REFCO and/or RCEF (REFCO and RCEF are hereinafter collectively referred to as “Regions”) under the Master
Agreement referenced above and all Schedules thereto (collectively, the “Agreement”). 
 NOW, THEREFORE,
because the Guarantor will be benefited by the success of the Companies and in consideration of the premises, the entering into of the Agreement (as hereinafter defined), in order to induce Regions to extend to the Companies from time to time such
extensions of credit, advances and forbearances as Regions in its sole discretion may deem prudent and wise; and for other good and valuable consideration, the adequacy, sufficiency and receipt of which are hereby acknowledged, the Guarantor agrees
as follows: the Guarantor unconditionally and absolutely hereby guarantees the due and punctual payment to Regions when and as the same shall become due and payable (whether by acceleration or otherwise) of the following (collectively, the
“Liabilities”): all indebtedness, obligations and liabilities of the Company to REFCO and/or RCEF of every kind, character and description whatsoever, direct or indirect, absolute or contingent, due or to become due, now existing or
hereafter incurred, contracted or arising, joint or several, liquidated or unliquidated under the Agreement, and regardless whether incurred as maker, drawer, endorser, surety, guarantor or otherwise, and all other leases or financings entered into
by the Company and Regions under the Agreement, and any and all extensions and renewals of all or any part of the same. 
 The
Guarantor further agrees that, in the event Regions grants to any Company one or more extensions or renewals of any of the Liabilities, or any part thereof, or permits or requires any other modification in any of the terms of the Liabilities, or any
part thereof, in any manner which may be acceptable to Regions, with or without notice to the Guarantor, this Guaranty shall, and is hereby made to extend to and cover such extended, renewed or modified Liabilities, on whatever terms and conditions
the same may be extended, renewed or modified, and without regard to the number of times or the manner in which the same may have been or shall be extended, renewed or modified. 

The Guarantor further agrees (a) to pay any and all of the Liabilities upon demand at any time after maturity thereof (whether by
acceleration or otherwise), including, without limitation, all rent or periodic payments due under the Agreement and all other obligations for payments to, or for the benefit of, Regions under the Agreement; (b) to be bound by all of the terms
and provisions appearing on the face of any instrument or agreement evidencing, securing, guaranteeing, or executed in connection with any of the Liabilities and of any renewal instrument or agreement (collectively, the “Documents”)
(including any terms waiving notice and agreeing to pay costs and expenses of collection in the event of default) just as though the Guarantor had signed such instrument or agreement; (c) that Regions will not be required first to resort to any
Company or any other maker, endorser, surety or guarantor (Company and each such company, maker, endorser, surety or guarantor being hereinafter individually called an “Obligor”) or to the security pledged or granted to Regions by
any instrument or agreement, or otherwise assigned or conveyed to it, but in case of default in the payment of any of the Liabilities Regions may forthwith look to the Guarantor for payment under the provisions hereof; and (d) that
Regions’ enforcement of the Guarantor’s obligations hereunder shall not be stayed or otherwise delayed by any claim (including without limitation, a counterclaim) that any Obligor may have against Regions. 

The Guarantor hereby further agrees that the obligations of the Guarantor hereunder are absolute, unconditional, present and continuing
guaranties of payment and not of collectibility, and shall not be subject to any counterclaim, recoupment, set-off, reduction or defense based upon any claim that the Guarantor may have against any Company, the Obligors or Regions and shall not be
discharged, impaired, modified or otherwise affected by (a) the unenforceability, non-existence, invalidity or non-perfection of (i) any of the Liabilities, (ii) any Documents, (iii) any renewal instrument or agreement or
(iv) any lien, pledge, assignment, security interest or conveyance given as security therefor; (b) any understanding or agreement that any other person, firm or corporation was or is to execute this Guaranty or any other document
evidencing, guaranteeing or securing the Liabilities, or any part thereof; (c) Regions’ resort or failure or refusal to resort to any other security or remedy for the collection of the Liabilities, or any part thereof; (d) the sale,
exchange, release, surrender, or impairment of any collateral or other security for the Liabilities, or any part thereof; (e) the insolvency or bankruptcy of any Obligor or the failure of Regions to file a claim against such bankrupt Obligor
for such Obligor’s liability or obligation to Regions; (f) any modification, amendment, supplement, or change in the status or terms of any of the Liabilities or any collateral or other security for the Liabilities, or any part thereof;
(g) any default by the Company in payment of any of the Liabilities; (h) any compromise, settlement, release, discharge, termination, waiver, or extension of time for payment, performance, or observance of, any obligation of any Obligor
with respect to any of the Liabilities; (i) the application of any payments, proceeds of collateral or other sums to any of the Liabilities in such order as Regions may elect; (j) any exercise or non-exercise of any right, remedy, power,
or privilege of Regions with respect to any of the Liabilities or any collateral or other security therefor; (k) any failure, omission, delay, or lack of diligence on the part of Regions to enforce, assert, or exercise any such right, power,
privilege, or remedy; (l) any claim (including, but not limited to, a counterclaim) that any Obligor may have against Regions; or (m) any other event, circumstance or condition, whether or not the Guarantor shall have notice or knowledge
thereof. 
 The Guarantor further agrees that it shall not be necessary for Regions to give the Guarantor notice of or to obtain
consent or approval of the Guarantor in connection with, (a) the making of any advances or any extensions of credit or the terms thereof, or of any renewal or extension of or other modification with respect to the Liabilities, or any part
thereof; (b) any of the matters described in clauses (a) through (m) of the preceding paragraph; or (c) Regions’ acceptance of and reliance on this Guaranty. The terms hereof shall inure to the benefit of the successors and
assigns of Regions and shall be binding, jointly and severally, upon the Guarantor, its successors and assigns. 

 Neither any failure nor any delay on the part of Regions in exercising any right, power or
privilege under this Guaranty shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further exercise or the exercise of any other right, power or privilege. No modification, amendment or waiver of
any provision of this Guaranty shall be effective unless in writing and signed by a duly authorized officer of Regions, and then the same shall be effective only in the specific instance and for the purpose for which given. No notice to or demand on
the Guarantor in any case shall entitle the Guarantor to any other or further notice or demand in the same, similar or other circumstances. 
 The Guarantor hereby agrees to indemnify and hold Regions harmless against any loss or expense, including reasonable attorneys’ fees and disbursements, that may result from any failure of any Obligor
to pay any of the Liabilities when and as due and payable or that may be incurred by or on behalf of Regions in enforcing payment of any of the Liabilities against any of the Guarantor or any of the Obligors. 

The Guarantors to the extent it now is or hereafter becomes an “insider”, as defined in 11 U.S.C. §101 (or any amendment
or successor thereto or replacement thereof), of any Company hereby waives and relinquishes all rights (including, without limitation, rights of subrogation) that the Guarantor now has or hereafter may have to recover from or be reimbursed by the
Companies or the Companies’ property, or from any person, firm, or corporation that may now or hereafter have such a right to recover from or be reimbursed by any Company or the Companies’ property, any amounts paid by the Guarantor to
satisfy, in whole or in part, the Liabilities. The provisions of this paragraph are made for the express benefit of the Companies as well as Regions and may be enforced independently by any Company. 

The Guarantor further agrees that this Guaranty shall remain in full force and effect until revoked or terminated by a written
instrument, signed by the Guarantor and delivered to Regions and acknowledged in writing by Regions, and even after any such revocation or termination, shall be and remain effective as to any Liabilities then outstanding; and that this Guaranty
shall not be construed as being terminated by payment in full of the Liabilities to Regions, if, thereafter, in the absence of written revocation or termination by the Guarantor acknowledged by Regions, the Company obtains or incurs additional or
new Liabilities. Notwithstanding the foregoing sentence, this Guaranty and the Guarantor’s obligations hereunder shall continue to be effective or be automatically reinstated, as the case may be, any time payment of all or any part of the
Liabilities is recovered (a “Recovered Payment”) from Regions as a result of a preference or other claim made under any bankruptcy, insolvency, dissolution, liquidation, reorganization, receivership, or similar law or otherwise. The
collateral, if any, securing this Guaranty may be held by Regions until it is satisfied that all time periods during which the payment of all or any part of the Liabilities may be recovered from Regions as a result of a preference or other claim
under any bankruptcy, insolvency, dissolution, liquidation, reorganization, receivership, or similar law or otherwise have elapsed. The Guarantor will notify Regions immediately and in writing if Guarantor’s mailing address changes. 

Any act or circumstance that shall toll any statute of limitations applicable to the Liabilities, or any of them, shall also toll the
statute of limitations applicable to the Guarantor’s liability for the Liabilities under this Guaranty. 
 The term
“Guarantor” as used herein refers to Forbes Energy Services Ltd. The Guarantor is prohibited from assigning this Guaranty, or their obligations and duties hereunder, without the advance written approval of Regions. 

This Guaranty shall be governed by, and construed in accordance with, the laws of the State of New York. THE GUARANTOR HEREBY WAIVES ALL
RIGHTS TO TRIAL BY JURY IN ANY LITIGATION ARISING UNDER THIS GUARANTY. For purposes of any action or proceeding involving this Guaranty, the Guarantor hereby expressly submits to the jurisdiction and venue of all federal and state courts located in
the State of New York, New York County, and consents to be served with any process on paper by registered mail or by personal service within or without said state and county in accordance with applicable law, provided a reasonable time for
appearance is allowed. The Guarantor, to the fullest extent it may effectively do so, waives the defense of an inconvenient forum of any such action or proceeding. Nothing in this paragraph shall affect the right of Regions to serve legal process in
any other manner permitted by law or affect the right of any party to bring any action or proceeding in the courts of any other jurisdiction. The provisions of this Guaranty shall be severable and if any provision shall be invalid, void or
unenforceable in whole or in part for any reason, the remaining provisions shall remain in full force and effect. 
 This
Guaranty and the other Documents contain the entire understanding and agreement between the Guarantor and Regions with respect to the obligations of the Guarantor hereunder and supersede any prior agreements, understandings, promises, and statements
with respect to such obligations. 
 Witness the signature of the undersigned on the day and year first written above.

 NOTICE TO SIGNERS 
 You are being asked to guarantee all obligations and liabilities of the Company to Regions, including all future obligations of the Company entered into with Regions prior to the time you revoke or
terminate this Guaranty in writing as set forth in this Guaranty and including all payment or other performance due under the Company’s Agreement or Documents with Regions whether or not any equipment or other personal property leased or
financed thereunder is satisfactory. Think carefully before you do. If the Company doesn’t pay the obligations, you will have to. Be sure you can afford to pay if you have to, and that you want to accept this responsibility. 

You may have to pay up to the full amount of the obligations if the Company does not pay. You may also have to pay late fees or
collection costs, which increase this amount. 
 Regions can collect the obligations from you without first trying to
collect from the Company or any other party. Regions can use the same collection methods against you that can be used against the Company. 
 This notice is not part of the contract and does not vary or add to the terms of the Guaranty. 
 CAUTION - IT IS IMPORTANT THAT YOU THOROUGHLY READ THIS CONTRACT BEFORE YOU SIGN IT.

 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. 

  
 3 

 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 

  
 4 

 
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:

delivered (which deliveries may be by facsimile or other electronic method of delivery) shall be deemed an original and all of which together shall constitute one and the same instrument.

 16. No Assignment of Claims. Employee represents and agrees that Employee has
not transferred or assigned, to any person or entity, any claim involving Matador, or any portion thereof or interest therein.
