To receive a Separation Benefit in connection with a reduction in force or other Termination of Employment affecting an employee, an Eligible Employee must sign the following Separation and Release Agreement "A" provided by the Company:

(Employing Company) (“Unit”) and (Employee Name) (“Employee” or, “you”) hereby agree as follows:

Your employment will end/ended (Date Employment Ends).

In consideration for your agreement to the terms and conditions of this Separation and Release Agreement (“Agreement”), Unit will pay you $_________.00 (“Separation Benefit”), in accordance with and subject to the terms of the Amended and Restated Separation Benefit Plan of Unit Corporation and Participating Subsidiaries (the “Plan”). You agree to comply with all terms of the plan.

Payments will be paid in substantially equal installments in accordance with the Agreement.

You know that state and federal laws, including the Age Discrimination in Employment Act and Title VII of the Civil Rights Act of 1964, as amended, prohibit employment discrimination based on age, sex, race, color, national origin, religion, handicap, disability, or veteran status, and that these laws are enforced through the United States Equal Employment Opportunity Commission (“EEOC”), United States Department of Labor, and State Human Rights Agencies and courts of competent jurisdiction.

In exchange for the Separation Benefit described in this Agreement, you agree, on behalf of yourself, your legal representatives, heirs and beneficiaries, to fully and forever relieve, release and discharge Unit, its past, present and future successors, assigns, parent, subsidiaries, operating units, affiliates and divisions (and the agents, representatives, managers, owners, shareholders, officers, directors, employees and attorneys of those entities) (collectively referred to in this Agreement as the “Released Parties”), from all claims, debts, liabilities, demands, obligations, promises, acts, agreements, costs, expenses, damages, actions, and causes of action, whether in law or in equity, whether known or unknown, suspected or unsuspected, arising from your employment with and termination from Unit, as well as any injuries or damages suffered during the course of your employment with Unit, including, but not limited to, any and all claims under Title VII of the Civil Rights Act of 1964 (42 U.S.C. § 2000e, et seq.), as amended by the Civil Rights Act of 1991, which prohibits discrimination and/or harassment in employment based on race, color, national origin, religion or sex; the Civil Rights Act of 1966 (42 U.S.C. §1981, 1983 and 1985), which prohibits violations of civil rights; the Age Discrimination in Employment Act of 1967, as amended, (29 U.S.C. §621, et seq.), which prohibits age discrimination in employment; Section 510 of the Employment Retirement Income Security Act of 1974, as amended (“ERISA”) (29 U.S.C. § 1140), which protects employees from employment discrimination relative to certain employee benefits; the Americans with Disabilities Act of 1990, as amended (42 U.S.C. §12101, et seq.) which prohibits discrimination against the disabled; the Family and Medical Leave Act of 1993 (29 U.S.C. §2601, et seq.), which provides medical and family leave; the Genetic Information Nondiscrimination Act (42 U.S.C. § 2000ff-10), which prohibits discrimination based on genetic information; Uniformed Services Employment and Re-Employment Rights Act of 1994 (38 U.S.C. §§ 4301 et seq.), which prohibits discrimination based on U.S. military service; the Fair Labor Standards Act (42 U.S.C. §201, et seq.), including the Wage and Hour Laws relating to payment of wages; claims for Workers’ Compensation and any and all other federal, state and local laws and regulations, including claims under applicable state anti-discrimination laws.

1 NTD: Additional language to be added to release of any employees are employed in California.

The waiver and release of liability in this Agreement also includes, but is not limited to, a release of the Released Parties by you of any claims for severance pay or severance benefits beyond those specifically set forth in this Agreement, breach of contract, mental pain suffering and anguish, emotional upset, impairment of economic opportunities, unlawful interference with employment rights, defamation, intentional or negligent infliction of emotional distress, fraud, wrongful termination, wrongful discharge in violation of public policy, breach of any express or implied covenant of good faith and fair dealing, that Unit has dealt with you unfairly or in bad faith, and all other common law contract and tort claims.

Nothing in this Agreement, however, releases or diminishes any claims for benefits to which you may be entitled from or under any plan of Unit that is governed by ERISA. Except as described below, you agree and covenant not to file any suit, charge or complaint against the Released Parties in any court or administrative agency, with regard to any claim, demand, liability or obligation arising out of your employment with Unit or separation from Unit. You further represent that no claims, complaints, charges, or other proceedings are pending in any court, administrative agency, commission or other forum relating directly or indirectly to your employment by Unit.

Despite the above provisions or anything else contained in this Agreement to the contrary, this Agreement does not operate to release any claims that may not be released as a matter of law or any claims or rights with respect to the Separation Benefit. Further, this Agreement will not prevent you from doing any of the following:

a.obtaining unemployment compensation, state disability insurance or workers’ compensation benefits from the appropriate agency of the state in which you live and work, provided you satisfy the legal requirements for those benefits (nothing in this Agreement, however, guarantees or otherwise constitutes a representation of any kind that you are entitled to those benefits);

b.asserting any right that is created or preserved by this Agreement, like your right to receive the Separation Benefit; and

c.filing a charge with or participating in any investigation or proceeding conducted by the EEOC or a comparable state or local agency. Notwithstanding the foregoing, you agree that you are giving up (and hereby do give up) any rights to receive remedial relief (like reinstatement, back pay, or front pay) or monetary damages in any charge, complaint, or lawsuit filed by you or by anyone else on your behalf.

As further consideration for the payment of the Separation Benefit, you agree that you will not, in any capacity directly or indirectly and on your own behalf or on behalf of any other person or entity, during the period of time you are receiving Separation Benefits, either (a) solicit or attempt to induce any current customer of Unit to cease doing business with Unit or (b) solicit or attempt to induce any employee of Unit to sever the employment relationship (collectively, the “Protection of Business Requirements”).

Except as provided in the next paragraph, in the event you violate the Protection of Business Requirements, you will not be entitled to any further payments of Separation Benefits under the Plan or this Agreement and you will be obligated to repay Unit all Separation Benefit payments previously received under the Plan and this Agreement.

You agree that you have carefully read and fully understand all the provisions of this Agreement. This is the entire Agreement between you and Unit and is legally binding and enforceable. You agree that you have not relied on any representation or statement, written or oral, not set forth in this Agreement when signing this Agreement.

The parties agree that if a lawsuit relating or pertaining to this Agreement is filed, then the prevailing party will be entitled to collect from the other party the reasonable attorney fees, costs, charges, and expenses it incurs. For purposes of this paragraph, “prevailing party” means the party who has obtained the majority of relief on the disputed claim(s), whether by court order, verdict, or voluntary dismissal (except for in the case of a mutual settlement).

This Agreement shall be governed and interpreted under federal law and the laws of the State of Oklahoma, notwithstanding that State’s choice of law provisions; provided, however, that notwithstanding the foregoing, should state law apply and not be preempted by ERISA, the non-competition provisions contained in Section 4.2 of the Plan shall be governed by and construed in accordance with the law of the State of Delaware, without regard to the conflicts of law principles of such state. If any part of this Agreement is held by a court of competent jurisdiction to be void or voidable, that holding will not apply to render void or voidable the provisions of this Agreement not encompassed in the court’s holding. Where necessary to maintain this Agreement’s validity, a court of competent jurisdiction may modify the terms of this Agreement to the extent necessary to effectuate its purposes as demonstrated by the terms and conditions stated in this Agreement.

You knowingly and voluntarily sign this Agreement.
