NOW, THEREFORE, in consideration of such employment and the mutual covenants and promises herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Executive agree as follows:

1 EMPLOYMENT AND RESPONSIBILITIES

Subject to the terms set forth herein, the Company agrees to employ the Executive as President and Chief Executive Officer of the Company commencing on May 15, 2014 (such date, the “Effective Date”), and Executive hereby accepts such employment.

The Executive shall also serve the Company and its subsidiaries and affiliates in such capacities as the Board may request. While employed, the Executive shall report to the Chairman of the Board, and Executive shall devote his full business time and attention to the business and affairs of the Company, and shall use his best efforts to advance the interests of the Company; provided that, Executive may (i) serve on for-profit boards or committees with the prior written approval of the Board; or (ii) serve on civic or charitable boards or committees, provided, that such activities do not, individually or in the aggregate, interfere with the performance of the Executive’s duties and responsibilities with respect to the Company.

2 TERM

This Agreement shall be effective as of the Effective Date. The Executive’s employment hereunder shall begin on the Effective Date and shall continue until the day preceding the third anniversary of the Effective Date, unless terminated prior thereto by the Company or the Executive in accordance with Section 5 below (the “Expiration Date” and such period of employment being the “Employment Period”). Nothing in this Agreement shall mandate or prohibit a continuation of the Executive’s employment following the expiration of the Employment Period upon such terms and conditions as the Company and the Executive may agree, and thereafter, the Executive shall be employed on an at-will basis unless the parties agree to the contrary.

(ii) Notwithstanding the foregoing, the Company agrees and acknowledges that the provisions of this Section 6.4 relating to ownership and disclosure of Work Product do not apply to any inventions or other subject matter for which no equipment, supplies, facility, or trade secret information of the Company or an affiliate was used and that are developed entirely on Executive’s own time, unless: (a) the invention or other subject matter relates (1) to the business of the Company or an affiliate, or (2) to the actual or demonstrably anticipated research or development of the Company or any affiliate, or (b) the invention or other subject matter results from any work performed by the Executive for the Company or any affiliate.

6.6 Right to Injunction; Survival of Undertakings

(i) In recognition of the confidential nature of the Confidential Information, and in recognition of the necessity of the limited restrictions imposed by this Agreement, the Executive and the Company agree that it would be impossible to measure solely in money the damages which the Company would suffer if the Executive were to breach any of his obligations hereunder. The Executive acknowledges that any breach of any provision of this Agreement would irreparably injure the Company. Accordingly, the Executive agrees that if he breaches any of the provisions of Section 6 of this Agreement, the Company shall be entitled, in addition to any other remedies to which the Company may be entitled under this Agreement or otherwise, to an injunction to be issued by a court of competent jurisdiction, to restrain any breach, or threatened breach, of any provision of this Agreement without the necessity of posting a bond or other security therefor, and the Executive hereby waives any right to assert any claim or defense that the Company has an adequate remedy at law for any such breach.

(ii) If a court determines that any covenant included in this Section 6 is unenforceable in whole or in part because of such covenant’s duration or geographical or other scope, such court shall have the power to modify the duration or scope of such provision, as the case may be, so as to cause such covenant as so modified to be enforceable. Furthermore, if a court determines that a certain form of remedy or relief sought by the Company for the breach of a covenant included in this Section 6 is unavailable under applicable law, such a finding shall not prohibit the Company from obtaining a different form of remedy or relief with respect to such breach which such court has not found to be unavailable.

(iii) All of the provisions of this Agreement shall survive any separation from service of the Executive.

6.7 Effect of Breach of Covenants. In the event that the Executive violates or is in breach of any of the restrictive covenant contained in this Agreement or the Release, the Executive forfeits his right to receive any payment or benefit under this Agreement.

6.8 Survival of Representations. The provisions contained in this Section 6 shall survive the Expiration Date and the termination of the Executive’s employment with the Company.

7 SECTION 409A

7.1 Overview. The intent of the parties is that the payments and benefits under this Agreement comply with or be exempt from Section 409A and the regulations and guidance promulgated thereunder (collectively, “Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”) and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. If the Executive notifies the Company that he has received advice of a licensed attorney with tax experience that any provision of this Agreement would cause the Executive to incur any additional tax or interest under Section 409A (with specificity as to the reason therefor) or the Company independently makes such determination, the Company may, to the extent possible and after consulting with the Executive, reform such provision to try to comply with Section 409A through good faith modifications to the minimum extent reasonably appropriate to conform with Section 409A. To the extent that any provision hereof is modified in order to comply with or be exempt from Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Executive and the Company of the applicable provision without violating the provisions of Section 409A.

7.2 Separation from Service. If any payment, compensation or other benefit provided to the Executive under this Agreement in connection with his “separation from service” (within the meaning of Section 409A) is determined, in whole or in part, to constitute “nonqualified deferred compensation” within the meaning of Section 409A and the Executive is a specified employee (as defined in Section 409A(2)(B)(i)) at the time of separation from service, no part of such payments shall be paid before the day that is six (6) months plus one (1) day after the date of separation or, if earlier, ten (10) business days following the Executive’s death (the “New Payment Date”). The aggregate of any payments and benefits that otherwise would have been paid and/or provided to the Executive during the period between the Termination Date and the New Payment Date shall be paid to the Executive in a lump sum on such New Payment Date. Thereafter, any payments and/or benefits that remain outstanding as of the day immediately following the New Payment Date shall be paid without delay over the time period originally scheduled, in accordance with the terms of this Agreement. Notwithstanding anything to the contrary herein, to the extent that the foregoing delay applies to the provision of any ongoing welfare benefits, the Executive shall pay the full cost of premiums for such welfare benefits due and payable prior to the New Payment Date and the Company shall pay the Executive an amount equal to the amount of such premiums which otherwise would have been paid by the Company during such period on or within five (5) business days following the New Payment Date.

7.3 Termination of Employment. A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits subject to Section 409A upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Section 409A, and for purposes of any such provision of this Agreement, references to a “resignation,” “termination,” “terminate,” “termination of employment” or like terms shall mean separation from service (within the meaning of Section 409A).

13

7.4 Expenses and Reimbursements. All expenses or other reimbursements as provided herein shall be payable in accordance with the Company’s policies in effect from time to time, but in any event shall be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by the Executive. With regard to any provision herein that provides for reimbursement of costs and expenses or in-kind benefits, except as permitted by Section 409A: (a) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit; and (b) the amount of expenses eligible for reimbursements or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year.

7.5 Installment Payments. For purposes of Section 409A, the Executive’s right to receive any installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days (e.g., payment shall be made within thirty (30) days following the Termination Date), the actual date of payment within the specified period shall be within the sole discretion of the Company.

7.6 No Representations or Warranties. Nothing contained in this Agreement shall constitute any representation or warranty by the Company or the Executive regarding compliance with Section 409A. The Company has no obligation to take any action to prevent the assessment of any excise tax under Section 409A on any person and none of the Company, its subsidiaries or affiliates, or any of their employees or representatives shall have any liability to the Executive with respect thereto.

If the Executive should die while any amounts are still payable, or any benefits are still required to be provided, to the Executive hereunder, all such amounts or benefits, unless otherwise provided herein, shall be paid or provided in accordance with the terms of this Agreement to the Executive’s devisee, legatee or other designee or, if there be no such person, to the Executive’s estate.

8.4 Waivers

No delay or failure by any party hereto in exercising, protecting or enforcing any of its rights, titles, interests or remedies under this Agreement, and no course of dealing or performance with respect thereto, will constitute a waiver thereof. The express waiver by a party hereto of any right, title, interest or remedy in a particular instance or circumstance will not constitute a waiver thereof in any other instance or circumstance. All rights and remedies shall be cumulative and not exclusive of any other rights or remedies.

8.5 Conditions Precedent, Warranties

The Executive represents and warrants to the Company that (i) the Executive is not a party to or bound by any confidentiality, noncompetition, nonsolicitation, employment, consulting or other agreement or restriction which could conflict with, or be violated by, the performance of the Executive’s duties to the Company or obligations under this Agreement; and (ii) the Executive is not subject to any agreements with any other employer. The Executive

8.6 Recoupment. Notwithstanding anything herein to the contrary, this Agreement shall not impact any rights or restrictions under the Company’s Recoupment Policy for incentive compensation, as adopted by the Board and referred to in the Company’s most recent proxy statement filed with the Securities and Exchange Commission, as in effect on the date hereof or as such policy may be modified from time to time as a result of regulations to which the Company is subject, and the Executive acknowledges and agrees he remains subject to the terms of such policy following the Termination Date.

8.7 Severability

If any provision of this Agreement is held invalid, illegal or unenforceable under applicable law, for any reason, including, without limitation, the duration of such provision, its geographical scope or the extent of the activities prohibited or required by it, then, to the full extent permitted by law (a) all other provisions will remain in full force and effect and will be liberally construed in order to carry out the intent of the parties hereto as nearly as may be possible, (b) such invalidity, illegality or unenforceability will not affect the validity, legality or enforceability of any other provision hereof, and (c) any court or arbitrator having jurisdiction thereover shall (and will have the power to) reform such provision to the extent necessary for such provision to be enforceable under applicable law.

8.8 Counterparts

This Agreement, and any amendment or modification entered into pursuant to Section 9.10 hereof, may be executed in any number of counterparts (including facsimile counterparts), each of which counterparts, when so executed and delivered, shall be deemed to be an original and all of which counterparts, taken together, will constitute one and the same instrument.

8.9 Applicable Law

This Agreement, and all claims or causes of action or other matters (whether in contract, tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of this Agreement or the consummation of any of the transactions contemplated hereby, shall be governed by and construed in accordance with the laws of the state of Oklahoma applicable to contracts made and performed in Oklahoma, excluding any conflict or choice of law rule or principle that might otherwise refer construction or interpretation thereof to the substantive laws of another jurisdiction.

8.10 Entire Agreement

This Agreement, the CIC Agreement and the award agreements under the Equity Plan or otherwise providing for equity awards under Section 3.4 hereof (the “Equity Awards”) constitute the entire agreement between the Company and the Executive relating to employment of the Executive with the Company and the subject matter addressed herein, and supersede and cancel

16

any and all previous or contemporaneous contracts, arrangements or understandings, whether oral or written between the Company and the Executive relating to his employment with or termination from the Company. If any provision of any agreement, plan, program, policy, arrangement or other written document between or relating to the Company and the Executive (hereinafter referred to as an “Other Document”) conflicts with any provision of this Agreement, the CIC Agreement and the Equity Awards, the provisions of this Agreement, the CIC Agreement and the Equity Awards shall control and prevail. Notwithstanding the foregoing, if any provision of an Other Document conflicts with duration of any restrictive covenant set forth in Section 6 hereof, the provision providing for the greater length of time shall prevail. No amendment, modification, waiver, termination or discharge of any provision of this Agreement, nor consent to any departure therefrom by either party, will in any event be effective unless the same is in writing, specifically identifying this Agreement and the provision intended to be amended, modified, waived, terminated or discharged and signed by the Company and the Executive, and will be effective only in the specific instance and for the specific purpose for which given.
