 WITNESSETH: 
 WHEREAS, the Executive is
a key employee of the Company or one or more of its Subsidiaries (as defined below) and has made and is expected to continue to make major contributions to the short and long-term profitability, growth and financial strength of the Company;

 WHEREAS, the Company recognizes that the possibility of a Change in Control (as defined below) exists and that such possibility, and the
uncertainty it may create among management, may result in the distraction or departure of management personnel, to the detriment of the Company and its stockholders; 
 WHEREAS, the Company desires to assure itself of both present and future continuity of management and desires to establish certain minimum severance benefits for certain of its senior executives, including the
Executive, applicable in the event of a Change in Control; and 
 WHEREAS, the Company wishes to ensure that its senior executives are not
unduly distracted by the circumstances attendant to the possibility of a Change in Control and to encourage the continued attention and dedication of such executives, including the Executive, to their assigned duties with the Company, and

 WHEREAS, the Company desires to provide additional inducement for the Executive to remain in the employ of the Company.

his duties) and his continued willful failure to cure such breach or nonperformance within the time period set by the Board but in no event less than thirty (30) business days after his receipt of such notice; and, for purposes of this clause
(E), no act or failure to act on Executive’s part shall be deemed “willful” unless it is done or omitted by Executive without his reasonable belief that such action or omission was in the best interest of the Company (assuming

willful under this Agreement).

immediately following such Merger, substantially all of the holders of the Outstanding Company Voting Securities immediately prior to Merger beneficially own, directly or indirectly, more than 50% of the common stock of the corporation resulting

other disposition, substantially all of the holders of the Outstanding Company Voting Securities immediately prior to the consummation of such sale or other disposition beneficially own, directly or indirectly, more than 50% of the common stock of

Executive. In the event that the Parties are not able to agree on the choice of a physician, each shall select one physician who, in turn, shall select a third physician to render such certification. All costs relating to the determination of
whether Executive has incurred a Disability shall be paid by the Company. Executive agrees to submit to any examinations that are reasonably required by the attending physician or other healthcare service providers to determine whether he has a
Disability.

Executive’s employment for Cause or Disability, without Executive’s express written consent: 
 (i) A reduction by
more than 10% in Executive’s Base Salary and Target Bonus, as compared with the Base Salary and most recently established Target Bonus, or if no Target Bonus has been set then the Bonus most recently paid, prior to the Change in Control or the

Company;

any other material provision of this Agreement; or

Executive cannot terminate his employment hereunder for Good Reason unless he (A) first notifies the Board in writing of the event (or events) which the Executive believes constitutes a Good Reason event under subparagraphs (i), (ii),
(iii) or (iv) (above) within 120 days from the date of such event, and (B) provides the Company with at least 30 days to cure, correct or mitigate the Good Reason event so that it either (1) does not constitute a Good Reason event
hereunder or (2) Executive agrees, in writing, that after any such modification or accommodation made by the Company that such event shall not constitute a Good Reason event hereunder. 
  

 4 

 (j) “Retirement” means the termination of Executive’s employment
for normal retirement at or after attaining age sixty-five (65) provided that, on the date of his retirement, Executive has accrued at least five years of active service with the Company. 
 (k) “Retirement Plans” means the benefit plans of the Company that are intended to be qualified under
Section 401(a) of the Code and any supplemental executive retirement benefit plan or any other plan that is a successor thereto if the Executive was a participant in such Retirement Plan on the date of the Change in Control.

continuing until the earlier of (i) the second anniversary of the occurrence of the Change in Control, or (ii) the Executive’s death; provided, however, that commencing on each anniversary of the Change in Control, the Severance

be so extended. 
 (m) “Subsidiary” means any subsidiary as defined in Section l(f)(i).

the immediately preceding year, the Company or the Executive shall have given notice that it or the Executive, as the case may be, does not wish to have the Term extended; (ii) if a Change in Control occurs during the Term, the Term shall
expire and this Agreement will terminate on the last day of the Severance Period; and (iii) subject to Section 3(c), if, prior to a Change in Control, the Executive ceases for any reason to be an employee of the Company or any Subsidiary
(including termination arising in connection with the Company ceasing to beneficially own 50% or more of the Voting Stock of a Subsidiary), or ceases to be an employee at a level previously designated for the benefits set forth in Annex A
hereto, thereupon without further action the Term shall be deemed to have expired and this Agreement will immediately terminate and be of no further effect. For purposes of this Section l(n), the Executive shall not be deemed to have ceased to be an
employee of the Company and any Subsidiary by reason of the transfer of Executive’s employment between the Company and any Subsidiary, or among any Subsidiaries. 
 (o) “Termination Date” means the date on which the Executive’s employment is terminated (the effective date of which

dental or other insurance (whether funded by actual insurance or self-insured by the Company or a Subsidiary). 
 2. Operation of
Agreement. This Agreement will be effective and binding immediately upon its execution, but, anything in this Agreement to the contrary notwithstanding, except as provided in Section 3(c), this Agreement will not be operative unless and
until a Change in Control occurs. Upon the occurrence of a Change in Control at any time during the Term, without further action, this Agreement will become immediately operative. 
 3. Termination Following a Change in Control. 
 (a) In the event of the occurrence of a Change in Control, the Executive’s employment may be terminated by the Company or a Subsidiary during the Severance Period and the Executive will be entitled to the
benefits provided by Section 4 unless such termination is the result of the occurrence of one or more of the following events: 
 (i) The Executive’s death, Disability or Retirement; or 
 (ii) Cause. 
 If, during the Severance Period, the Executive’s employment is terminated by the Company or any Subsidiary other than pursuant to
Section 3(a)(i) or 3(a)(ii), the Executive will be entitled to the benefits provided by Section 4. 
 (b) In the
event of the occurrence of a Change in Control, the Executive may terminate employment with the Company and any Subsidiary during the Severance Period for Good Reason with the right to severance compensation as provided in Section 4.

 (c) Anything in this Agreement to the contrary notwithstanding, if a Change in Control occurs and not more than twelve
months prior to the date on which the Change in Control occurs, the Executive’s employment with the Company ceases at the previously designated level or is terminated by the Company (or the Executive terminates his employment for Good Reason),
such cessation or termination of employment will be deemed to be a cessation or termination of employment after a Change in Control for purposes of this Agreement if the Executive has reasonably demonstrated that such cessation or termination of
employment (i) was at the request of a third parry who has taken steps reasonably calculated to effect a Change in Control, or (ii) otherwise arose in connection with or in anticipation of a Change in Control. 
 (d) A termination by the Company pursuant to Section 3(a) or by the Executive pursuant to Section 3(b) will not affect any
rights that the Executive may have pursuant to any agreement, policy, plan, program or arrangement of the Company or Subsidiary providing Employee Benefits, which rights shall be governed by the terms thereof, except for any rights to severance
compensation to which Executive may be 

  

 6 

 
entitled upon termination of employment under any severance or employment agreement between the Company and the Executive which rights, to the extent not
greater than those provided by this Agreement, shall, during the Severance Period, be superseded by this Agreement. 
 4. Severance
Compensation. 
 (a) If, following the occurrence of a Change in Control, the Company or Subsidiary terminates the
Executive’s employment during the Severance Period other than pursuant to Section 3(a)(i) or 3(a)(ii), or if the Executive terminates his employment pursuant to Section 3(b), provided that the Executive executes a release
substantially in the form rendered by senior executives of the Company prior to the Change in Control, subject to Section 20, the Company will pay to the Executive the amounts described in Annex A in substantially equal monthly
installment payments over a 24-month period beginning within 30 days after the Termination Date including credited interest on the unpaid balance at six percent (6%) per annum and will continue to provide to the Executive the benefits described
on Annex A for the periods described therein. 
 (b) Without limiting the rights of the Executive at law or in equity,
if the Company fails to make any payment or provide any benefit required to be made or provided hereunder on a timely basis, the Company will pay interest on the amount or value thereof at an annualized rate of interest equal to six percent
(6%) per annum. Such interest will be payable as it accrues on demand. The Executive will also be entitled to recover attorneys’ fees, costs and expenses related to the Company’s failure to pay. 
 5. Limitation on Payments and Benefits. Notwithstanding any provision of this Agreement to the contrary, if any amount or benefit to be paid or
provided under this Agreement would be an “Excess Parachute Payment,” within the meaning of Section 280G of the Code, but for the application of this sentence, then the payments and benefits to be paid or provided under this Agreement
will be reduced to the minimum extent necessary (but in no event to less than zero) so that no portion of any such payment or benefit, as so reduced, constitutes an Excess Parachute Payment; provided, however, that the foregoing reduction will be
made only if and to the extent that such reduction would result in an increase in the aggregate payment and benefits to be provided, determined on an after-tax basis (taking into account the excise tax imposed pursuant to Section 4999 of the
Code, any tax imposed by any comparable provision of state law, and any applicable federal, state and local income and employment taxes). Whether requested by the Executive or the Company, the determination of whether any reduction in such payments
or benefits to be provided under this Agreement or otherwise is required pursuant to the preceding sentence will be made at the expense of the Company by the Company’s independent accountants in effect prior to the Change in Control. The fact
that the Executive’s right to payments or benefits may be reduced by reason of the limitations contained in this Section 5 will not of itself limit or otherwise affect any other rights of the Executive other than pursuant to this
Agreement. In the event that any payment or benefit intended to be provided under this Agreement or otherwise is required to be reduced pursuant to this Section 5, the Executive will be entitled to designate the payments and/or benefits to be
so reduced in order to give effect to this Section 5. The Company will provide the Executive with all information reasonably requested by the Executive to permit the Executive to make such designation. In the event that 

  

 7 

 
the Executive fails to make such designation within 10 business days of the Termination Date, the Company may effect such reduction in any manner it deems
appropriate. 
 6. No Mitigation Obligation. The Company hereby acknowledges that it will be difficult and may be impossible for the
Executive to find reasonably comparable employment following the Termination Date. Accordingly, the payment of the severance compensation by the Company to the Executive in accordance with the terms of this Agreement is hereby acknowledged by the
Company to be reasonable, and the Executive will not be required to mitigate the amount of any payment provided for in this Agreement by seeking other employment or otherwise, nor will any profits, income, earnings or other benefits from any source
whatsoever create any mitigation, offset, reduction or any other obligation on the part of the Executive hereunder or otherwise, except as expressly provided in the last sentence of Paragraph 2 of Annex A. 
 7. Confidentiality & Nondisparagement. 
 (a) During the Term, the Company agrees that it will disclose to Executive its confidential or proprietary information (as defined in this Section 7(a)) to the extent necessary for Executive to carry out his
obligations to the Company. The Executive hereby covenants and agrees that he will not, without the prior written consent of the Company, during the Term or thereafter disclose to any person not employed by the Company, or use in connection with
engaging in competition with the Company, any confidential or proprietary information of the Company. For purposes of this Agreement, the term “confidential or proprietary information” will include all information of any nature and in any
form that is owned by the Company and that is not publicly available (other than by Executive’s breach of this Section 7(a)) or generally known to persons engaged in businesses similar or related to those of the Company. In addition,
confidential or proprietary information will include, without limitation, the Company’s financial matters, customers, employees, industry contracts, strategic business plans, product development (or other proprietary product data), marketing
plans, and all other secrets and all other information of a confidential or proprietary nature. For purposes of the preceding two sentences, the term “Company” will also include any Subsidiary (collectively, the “Restricted
Group”). The foregoing obligations imposed by this Section 7(a) will not apply (i) during the Term, in the course of the business of and for the benefit of the Company, (ii) if such confidential or proprietary information has
become, through no fault of the Executive, generally known to the public or (iii) if the Executive is required by law to make disclosure (after giving the Company notice and an opportunity to contest such requirement). 
 (b) The Executive hereby covenants and agrees that the Executive will not make, publish or cause to be made or published any public or
private statement disparaging the Company or its present or former officers, directors or employees. 
 8. Remedies. Executive
acknowledges that the restrictions contained in Section 7 of this Agreement, in view of the nature of the Company’s business, are reasonable and necessary to protect the Company’s legitimate business interests, and that any violation
of this Agreement would result in irreparable injury to the Company. In the event of a breach or a threatened 

  

 8 

 
breach by Executive of any provision of Section 7 of this Agreement, the Company shall be entitled to a temporary restraining order and injunctive
relief restraining Executive from the commission of any breach, and to recover the Company’s attorneys’ fees, costs and expenses related to the breach or threatened breach. Nothing contained in this Agreement shall be construed as
prohibiting the Company from pursuing any other remedies available to it for any such breach or threatened breach, including, without limitation, the recovery of money damages, attorneys’ fees, and costs. These covenants and disclosures shall
each be construed as independent of any other provisions in this Agreement, and the existence of any claim or cause of action by Executive against the Company, whether predicated on this Agreement or otherwise, shall not constitute a defense to the
enforcement by the Company of such covenants and agreements. 
 9. Arbitration. Subject to Section 8, any dispute or other
controversy (hereafter a “Dispute”) arising under or in connection with this Agreement, whether in contract, in tort, statutory or otherwise, shall be finally and solely resolved by binding arbitration in Oklahoma City, Oklahoma,
administered by the American Arbitration Association (the “AAA”) in accordance with the Employment Dispute Resolution Rules of the AAA, this Section 9 and, to the maximum extent applicable, the Federal Arbitration Act. Such
arbitration shall be conducted by a single arbitrator (the “Arbitrator”). If the parties cannot agree on the choice of an Arbitrator within 30 days after the Dispute has been filed with the AAA, then the Arbitrator shall be selected
pursuant to the Employment Dispute Resolution Rules of the AAA. The Arbitrator may proceed to an award notwithstanding the failure of any party to participate in such proceedings. The prevailing party in the arbitration proceeding may be entitled to
an award of reasonable attorneys’ fees incurred in connection with the arbitration in such amount, if any, as determined by the Arbitrator in his discretion. The costs of the arbitration shall be borne equally by the parties unless otherwise
determined by the Arbitrator in the award. 
 To the maximum extent practicable, an arbitration proceeding hereunder shall be concluded
within 180 days of the filing of the Dispute with the AAA. The Arbitrator shall be empowered to impose sanctions and to take such other actions as the Arbitrator deems necessary to the same extent a judge could impose sanctions or take such other
actions pursuant to the Federal Rules of Civil Procedure and applicable law. Each party agrees to keep all Disputes and arbitration proceedings strictly confidential except for disclosure of information required by applicable law which cannot be
waived. 
 The award of the Arbitrator shall be (a) the sole and exclusive remedy of the parties, and (b) final and binding on the
parties hereto except for any appeals provided by the Federal Arbitration Act Only the district courts of Oklahoma shall have jurisdiction to enter a judgment upon any award rendered by the Arbitrator, and the parties hereby consent to the personal
jurisdiction of such courts and waive any objection that such forum is inconvenient. This Section 9 shall not preclude (i) the parties at any time from agreeing to pursue non-binding mediation of the Dispute prior to arbitration hereunder
or (ii) the Company from pursuing the remedies available under Section 8 in any court of competent jurisdiction. 
  

 9 

 10. Employment Rights. Nothing expressed or implied in this Agreement will create any right or
duty on the part of the Company or the Executive to have the Executive remain in the employment of the Company or any Subsidiary prior to or following any Change in Control. 
 11. Withholding of Taxes. The Company may withhold from any amounts payable under this Agreement all federal, state, city or other taxes as the
Company is required to withhold pursuant to any applicable law, regulation or ruling. 
 12. Successors and Binding Agreement.

 (a) The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganization
or otherwise) to all or substantially all of the business or assets of the Company, by agreement in form and substance reasonably satisfactory to the Executive, expressly to assume and agree to perform this Agreement in the same manner and to the
same extent the Company would be required to perform if no such succession had taken place. This Agreement will be binding upon and inure to the benefit of the Company and any successor to the Company, including without limitation any persons
acquiring directly or indirectly all or substantially all of the business or assets of the Company whether by purchase, merger, consolidation, reorganization or otherwise (and such successor shall thereafter be deemed the “Company” for the
purposes of this Agreement), but will not otherwise be assignable, transferable or delegable by the Company. 
 (b) This
Agreement will inure to the benefit of and be enforceable by the Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees and legatees. 
 (c) This Agreement is personal in nature and neither of the parties hereto will, without the consent of the other, assign, transfer or
delegate this Agreement or any rights or obligations hereunder except as expressly provided in Sections 12(a) and 12(b). Without limiting the generality or effect of the foregoing, the Executive’s right to receive payments hereunder will not be
assignable, transferable or delegable, whether by pledge, creation of a security interest, or otherwise, other than by a transfer by Executive’s will or by the laws of descent and distribution and, in the event of any attempted assignment or
transfer contrary to this Section 12(c), the Company will have no liability to pay any amount so attempted to be assigned, transferred or delegated. 
 13. Entire Agreement. This Agreement contains the entire agreement of the parties hereto with respect to the matters covered herein; moreover, this Agreement supersedes all prior and contemporaneous agreements
and understandings, oral or written, between the parties concerning the subject matter hereof. 
 14. Governing Law. The validity,
interpretation, construction and performance of this Agreement will be governed by and construed in accordance with the substantive laws of the State of Oklahoma, without giving effect to the principles of conflict of laws of such State. 

15. Validity. If any provision of this Agreement or the application of any provision hereof to any person or circumstance is held invalid,
unenforceable or otherwise illegal, the 

  

 10 

 
remainder of this Agreement and the application of such provision to any other person or circumstance will not be affected, and the provision so held to be
invalid, unenforceable or otherwise illegal will be reformed to the extent (and only to the extent) necessary to make it enforceable, valid or legal. 
 16. Miscellaneous. No provision of this Agreement may be modified, waived or discharged unless such waiver, modification or discharge is agreed to in writing signed by the Executive and the Company. No waiver
by either party hereto at any time of any breach by the other party hereto or compliance with any condition or provision of this Agreement to be performed by such other party will be deemed a waiver of similar or dissimilar provisions or conditions
at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, expressed or implied with respect to the subject matter hereof have been made by either party that are not set forth expressly in this Agreement.
References to Sections are to Sections of this Agreement. References to Paragraphs are to Paragraphs of an Annex to this Agreement. Any reference in this Agreement to a provision of a statute, rule or regulation will also include any successor
provision thereto. 
 17. Waiver of Breach. No waiver by either the Company or the Executive (each, a “Party”) of a breach
of any provision of this Agreement by any other Party, or of compliance with any condition or provision of this Agreement to be performed by such other Party, will operate or be construed as a waiver of any subsequent breach by such other Party or
any similar or dissimilar provision or condition at the same or any subsequent time. The failure of either Party hereto to take any action by reason of any breach will not deprive such Party of the right to take action at any time while such breach
continues. 
 18. Survival. Notwithstanding any provision of this Agreement to the contrary, the parties’ respective rights and
obligations under Sections 3(c), 4, 5, and 7 will survive any termination or expiration of this Agreement or the termination of the Executive’s employment following a Change in Control for any reason whatsoever. 
 19. Notices. For all purposes of this Agreement, all communications, including without limitation notices, consents, requests or approvals,
required or permitted to be given hereunder will be in writing. Any termination by the Company or the Executive shall be communicated by written notice which indicates the specific termination provision of this Agreement relied upon and sets forth

 Annex A 
 Severance Compensation 
 (1) A severance
benefit in an amount equal to [one - Vice Presidents} [two - Sr. Vice Presidents] [2 1/2 - Executive Vice Presidents]
[three—President & CEO] times the sum of (A) Base Salary (as in effect immediately prior to his Termination Date), plus (B) Bonus (in an amount equal to the current annual
Target Bonus for the full year in which the Termination Date occurred or if no Target Bonus has been established then the most recent Bonus paid), which benefit shall be paid in accordance with Section 4(a), subject to Section 20. 

 (2) For a period of 12 months following the Termination Date (the “Continuation Period”), the Company will arrange to
provide the Executive with Welfare Benefits substantially similar to those that the Executive was receiving or entitled to receive immediately prior to the Termination Date (or, if greater, immediately prior to the reduction, termination, or denial
described in Section l(i)(iii)). If and to the extent that any benefit described in this Paragraph 2 is not or cannot be paid or provided under any policy, plan, program or arrangement of the Company or any Subsidiary; as the case may be, then,
subject to Section 20, the Company will itself pay or provide for the payment to the Executive, his dependents and beneficiaries, in accordance with the Company’s payroll procedures (commencing with the first payroll period that begins not
later than thirty (30) days after such Termination Date) an amount equal to the cost of providing such Employee Benefits (at the same rate or level as such Employee Benefits were provided or available at the time such Employee Benefits were
required as a matter of law to be discontinued because Executive ceased to be employed by the Company) for the duration of the Continuation Period along with, in the case of any benefit described in this Paragraph 2 which is subject to tax because
it is not or cannot be paid or provided under any such policy, plan, program or arrangement of the Company or any Subsidiary, an additional amount such that after payment by the Executive, or his dependents or beneficiaries, as the case may be, of
all taxes so imposed, the recipient retains an amount equal to such taxes. Notwithstanding the foregoing, or any other provision of the Agreement, for purposes of determining the period of continuation coverage to which the Executive or any of his
dependents is entitled pursuant to Section 4980B of the Code under the Company’s medical, dental and other group health plans, or successor plans, the Executive’s “qualifying event” will be the termination of the
Continuation Period and the Executive will be considered to have remained actively employed on a full-time basis through that date. Further, for purposes of the immediately preceding sentence and for any other purpose, including, without limitation,
the calculation of service or age to determine the Executive’s eligibility for benefits under any retiree medical benefits or life insurance plan or policy, the Executive shall be considered to have remained actively employed on a full-time
basis through the termination of the Continuation Period. Without otherwise limiting the purposes or effect of Section 5 or this Paragraph 2, Employee Benefits otherwise receivable by the Executive pursuant to this Paragraph 2 will be reduced
to the extent comparable welfare benefits are actually received by the Executive from another employer during the Continuation Period following the Executive’s Termination Date, and any such benefits actually received by the Executive shall
promptly be reported by the Executive to the Company.

 Executive officers are also eligible to receive a cash award each year under the Company’s
2004 Key Officers Incentive Plan (filed as Exhibit 10.13 to the Company’s Form 10-K for the year ended December 31, 2005). An executive’s cash award is calculated by multiplying his annual salary at the end of the year by a percentage
set by the Compensation Committee of the Company’s Board (“Target Percentage”) then, applying an award formula adopted by the Committee for that year. The Target Percentages applicable to the Company’s principal executive
officer, principal financial officer and other named executive officers were increased in 2008 as shown in the following table.
