Notwithstanding the foregoing, no “Change of Control” shall be deemed to have occurred if there is consummated any transaction or series of integrated transactions immediately following which the record holders of the common stock of the Company immediately prior to such transaction or series of transactions continue to own, directly or indirectly, in the same proportions as their ownership in the Company, an entity that owns all or substantially all of the assets or voting securities of the Company immediately following such transaction or series of transactions.

Notwithstanding the foregoing:

(i) If Executive takes a leave of absence for purposes of military leave, sick leave or other bona fide leave of absence, Executive will not be deemed to have incurred a Separation from Service for the first six (6) months of the leave of absence, or if longer, for so long as Executive’s right to reemployment is provided either by statute or by contract.

(iii) If, following Executive’s termination of employment, Executive continues to provide services to the Company or a 409A Affiliate in a capacity other than as an employee, Executive will not be deemed to have Separated from Service as long as Executive is providing bona fide services at a rate that is greater than twenty percent (20%) of the level of services rendered by Executive, on average, during the immediately preceding 12 months of service.

(m) “Severance Payment” shall mean the Executive’s Base Salary at the time of the Termination Date plus the average of the annual bonuses earned by the Executive with respect to each of the three completed fiscal years of the Company preceding the year in which the Termination Date occurs (or such lesser number of fiscal years for which the Executive was employed by the Company as its Chief Executive Officer (beginning on the date hereof), with any partial year’s bonus being annualized with respect to such fiscal year) multiplied by the severance multiplier set forth above; provided that if Executive’s Termination Date occurs on or following a Change of Control, the multiplier described above shall be increased to the post-Change of Control

6

severance multiplier set forth above and any reduction in Executive’s Base Salary since the date of the Change of Control shall be ignored.

(n) “Successor” shall mean the person to which this Agreement is assigned upon a Sale of Business within the meaning of Section 10.

3. Employment of Executive.

(a) Position.

(i) Executive shall serve in the position set forth above in a full-time capacity. In such position, Executive shall have such duties and authority as is customarily associated with such position and shall have such other titles and duties, consistent with Executive’s position, as may be assigned from time to time by the Board.

(ii) Executive will devote Executive’s full business time and best efforts to the performance of Executive’s duties hereunder and will not engage in any other business, profession or occupation for compensation or otherwise which would conflict or interfere with the rendition of such services either directly or indirectly, without the prior written consent of the Board; provided that nothing herein shall preclude Executive, subject to the prior approval of the Board, from accepting appointment to or continue to serve on any board of directors or trustees of any business organization or any charitable organization; further provided in each case, and in the aggregate, that such activities do not conflict or interfere with the performance of Executive’s duties hereunder or conflict with Section 7.

(b) Base Salary. Orion shall pay Executive a Base Salary at the respective annual rate set forth above, payable in regular installments in accordance with the Company’s usual payroll practices. Executive shall be entitled to such increases in Executive’s base salary, if any, as may be determined from time to time by the Board.

(c) Bonus Incentives. Executive shall be entitled to participate in such annual and/or long-term cash and equity incentive plans and programs of Orion as are generally provided to the senior executives of Orion or as otherwise provided by the Board or the Compensation Committee thereof. On and after a Change of Control, to assure that Executive will have an opportunity to earn incentive compensation, the Executive shall be included in a bonus plan of the Employer which shall satisfy the standards described below (such plan, the “Bonus Plan”). Bonuses under the Bonus Plan shall be payable with respect to achieving such financial or other goals reasonably related to the business of the Company as the Company shall establish (the “Goals”), all of which Goals shall be attainable, prior to the end of the post-Change of Control renewal period (as set forth above), with approximately the same degree of probability as the most attainable goals under the Company’s bonus plan or plans as in effect at any time during the 180-day period immediately prior to the Change of Control (whether one or more, the “Company Bonus Plan”) and in view of the Company’s existing and projected financial and business circumstances applicable at the time. The amount of the bonus (the “Bonus Amount”) that Executive is eligible to earn under the Bonus Plan shall be no less than

7

100% of the Executive’s target award provided in such Company Bonus Plan (such bonus amount herein referred to as the “Targeted Bonus”), and in the event the Goals are not achieved such that the entire Targeted Bonus is not payable, the Bonus Plan shall provide for a payment of a Bonus Amount equal to a portion of the Targeted Bonus reasonably related to that portion of the Goals which were achieved. Payment of the Bonus Amount shall not be affected by any circumstance occurring subsequent to the end of the post-Change of Control renewal period, including termination of Executive’s employment.

(d) Employee Benefits. Executive shall be entitled to participate in the Company’s employee benefit plans (other than annual and/or long-term incentive programs, which are addressed in subsection (c)) as in effect from time to time on the same basis as those benefits are generally made available to other senior executives of Orion. On and after a Change of Control, Executive shall be included: (i) to the extent eligible thereunder (which eligibility shall not be conditioned on Executive’s salary grade or on any other requirement which excludes persons of comparable status to the Executive unless such exclusion was in effect for such plan or an equivalent plan immediately prior to the Change in Control of the Company), in any and all plans providing benefits for the Company’s salaried employees in general (including but not limited to group life insurance, hospitalization, medical, dental, and long-term disability plans) and (ii) in plans provided to executives of the Company of comparable status and position to Executive (including but not limited to deferred compensation, split-dollar life insurance, supplemental retirement, stock option, stock appreciation, stock bonus, cash bonus and similar or comparable plans); provided, that, in no event shall the aggregate level of benefits under the plans described in clause (i) and the plans described in clause (ii), respectively, in which Executive is included be less than the aggregate level of benefits under plans of the Company of the type referred to in such clause, respectively, in which Executive was participating immediately prior to the Change in Control.

(e) Business Expenses. The reasonable business expenses incurred by Executive in the performance of Executive’s duties hereunder shall be reimbursed by the Company in accordance with Company policies.

(f) Other Perquisites. Executive shall be entitled to receive the other benefits and perquisites set forth in Exhibit A.

4. Termination of Employment. Executive’s employment with the Company will terminate during the term of the Agreement, and this Agreement will terminate on the date of such termination, as follows:

(a) Executive’s employment will terminate upon Executive’s death.

(b) If Executive is Disabled, and if within thirty (30) days after Orion notifies the Executive in writing that it intends to terminate the Executive’s employment, the Executive shall not have returned to the performance of the Executive’s duties hereunder on a full-time basis, Orion may terminate the Executive’s employment, effective immediately following the end of such thirty (30)-day period.

(c) Orion may terminate Executive’s employment with or without Cause (other than as a result of Disability which is governed by subsection (b)) by providing written notice to Executive that indicates in reasonable detail the facts and circumstances

8

alleged to provide a basis for such termination. If the termination is without Cause, Executive’s employment will terminate on the date specified in the written notice of termination. If the termination is for Cause, the Executive shall have thirty (30) days from the date the written notice is provided, or such longer period as Orion may determine to be appropriate, to cure any conduct or act, if curable, alleged to provide grounds for termination of Executive’s employment for Cause. If the alleged conduct or act constituting Cause is not curable, Executive’s employment will terminate on the date specified in the written notice of termination. If the alleged conduct or act constituting Cause is curable but Executive does not cure such conduct or act within the specified time period, Executive’s employment will terminate on the date immediately following the end of the cure period. Notwithstanding the foregoing, a determination of Cause shall only be made in good faith by the Board, and after a Change of Control, by the Board of Directors of the Successor, which may terminate Executive for Cause only after providing Executive (i) written notice as set forth above, (ii) the opportunity to appear before such board and provide rebuttal to such proposed termination, and (iii) written notice following such appearance confirming such termination and certifying that the decision to terminate Executive for Cause was approved in good faith by at least sixty-six percent (66%) of the members of such board, excluding Executive. Unless otherwise directed by Orion, from and after the date of the written notice of proposed termination, Executive shall be relieved of his duties and responsibilities and shall be considered to be on a paid leave of absence pending any final action by the Board or the Board of Directors of the Successor confirming such proposed termination.

(d) Executive may terminate his employment for or without Good Reason by providing written notice of termination to Orion that indicates in reasonable detail the facts and circumstances alleged to provide a basis for such termination. If Executive is alleging a termination for Good Reason, Executive must provide written notice to Orion of the existence of the condition constituting Good Reason within ninety (90) days of the initial existence of such condition, and Orion must have a period of at least thirty (30) days following receipt of such notice to cure such condition. If such condition is not cured by Orion within such thirty (30)-day period, Executive’s termination of employment from the Company shall be effective on the date immediately following the end of such cure period.

5. Payments upon Termination.

(a) Entitlement to Severance. Subject to the other terms and conditions of this Agreement, Executive shall be entitled to the Accrued Benefits, and to the severance benefits described in subsection (c), in either of the following circumstances while this Agreement is in effect:

(i) Executive’s employment is terminated by Orion without Cause, except in the case of death or Disability; or

(ii) Executive terminates his employment with the Company for Good Reason.

If Executive dies after receiving a notice by Orion that Executive is being terminated without Cause, or after providing notice of termination for Good Reason, the Executive’s estate, heirs and beneficiaries shall be entitled to the Accrued Benefits and the severance

9

benefits described in subsection (c) at the same time such amounts would have been paid or benefits provided to Executive had he or she lived.

(b) General Release Requirement. As an additional prerequisite for receipt of the severance benefits described in subsection (c), Executive must execute, deliver to Orion, and not revoke (to the extent Executive is allowed to do so) a General Release.

(c) Severance Benefits; Timing and Form of Payment. Subject to the limitations imposed by Section 6, if Executive is entitled to severance benefits, then:

(i) Company shall pay Executive the Severance Payment in a lump sum within ten (10) days following the Executive’s Separation from Service, or if later, the date on which the General Release is no longer revocable, or if later, the date on which the amount payable under Section 6 is determined, but in no event may be payment be made more than 2 ¹/₂ months after the year in which Executive’s Separation from Service occurs;

(ii) At the same time that the Severance Payment is made, Company shall pay Executive a lump sum amount equal to the Executive’s annual target cash bonus opportunity (if any) as established by the Board or the Compensation Committee of the Board for the fiscal year in which the Separation from Service occurs, multiplied by a fraction, the numerator of which is the number of days that have elapsed during the annual performance period to the date of the Executive’s Separation from Service and the denominator of which is 365; and

(iii) Executive shall be entitled to pay premiums for COBRA continuation coverage for the length of such coverage at the same rate as is being charged to active employees for similar coverage.

All payments shall be subject to payroll taxes and other withholdings in accordance with the Company’s (or the applicable employer of record’s) standard payroll practices and applicable law.

(d) Other Termination of Employment. If Executive’s employment terminates for any reason other than those described in subsection (a), the Executive (or the Executive’s estate in the event of his death), shall be entitled to receive only the Accrued Benefits. Executive must be terminated for Cause pursuant to and in accordance with Section 4(c) of this Agreement in order for the consequences of such a Cause termination to apply to Executive under any stock option or similar equity award agreement with the Company to which Executive is then a party. The Company’s obligations under this Section 5 shall survive the termination of this Agreement.

6. Limitations on Severance Payments and Benefits. Notwithstanding any other provision of this Agreement, if any portion of the Severance Payment or any other payment under this Agreement, or under any other agreement with or plan of the Company (in the aggregate “Total Payments”), would constitute an “excess parachute payment,” then the Total Payments to be made to Executive shall be reduced such that the value of the aggregate Total Payments that Executive is entitled to receive shall be One Dollar ($1) less than the maximum amount which Executive may receive without becoming subject to the tax imposed by Code Section 4999 or which the Company may pay without loss of deduction under Code

10

Section 280G(a); provided that the foregoing reduction in the amount of Total Payments shall not apply if the After-Tax Value to Executive of the Total Payments prior to reduction in accordance herewith is greater than the After-Tax Value to Executive if Total Payments are reduced in accordance herewith. For purposes of this Agreement, the terms “excess parachute payment” and “parachute payments” shall have the meanings assigned to them in Code Section 280G, and such “parachute payments” shall be valued as provided therein. Present value for purposes of this Agreement shall be calculated in accordance with Code Section 1274(b)(2). Within twenty (20) business days following delivery of the notice of termination or notice by Orion to Executive of its belief that there is a payment or benefit due Executive that will result in an excess parachute payment as defined in Code Section 280G, Executive and Orion, at Orion’s expense, shall obtain the opinion (which need not be unqualified) of nationally recognized tax counsel selected by Orion’s independent auditors and acceptable to Executive in Executive’s sole discretion, which opinion sets forth: (A) the amount of the Base Period Income, (B) the amount and present value of Total Payments, (C) the amount and present value of any excess parachute payments without regard to the limitations of this Section 6, (D) the After-Tax Value of the Total Payments if the reduction in Total Payments contemplated under this Section 6 did not apply, and (E) the After-Tax Value of the Total Payments taking into account the reduction in Total Payments contemplated under this Section 6. As used in this Section 6, the term “Base Period Income” means an amount equal to Executive’s “annualized includible compensation for the base period” as defined in Code Section 280G(d)(1). For purposes of such opinion, the value of any noncash benefits or any deferred payment or benefit shall be determined by Orion’s independent auditors in accordance with the principles of Code Sections 280G(d)(3) and (4), which determination shall be evidenced in a certificate of such auditors addressed to Orion and Executive. For purposes of determining the After-Tax Value of Total Payments, Executive shall be deemed to pay federal income taxes and employment taxes at the highest marginal rate of federal income and employment taxation in the calendar year in which the Termination Payment is to be made and state and local income taxes at the highest marginal rates of taxation in the state and locality of Executive’s domicile for income tax purposes on the date the Termination Payment is to be made, net of the maximum reduction in federal income taxes that may be obtained from deduction of such state and local taxes. Such opinion shall be dated as of the Termination Date and addressed to Orion and Executive and shall be binding upon the Company and Executive. If such opinion determines that there would be an excess parachute payment and that the After-Tax Value of the Total Payments taking into account the reduction contemplated under this Section is greater than the After-Tax Value of the Total Payments if the reduction in Total Payments contemplated under this Section did not apply, then the Termination Payment hereunder or any other payment determined by such counsel to be includible in Total Payments shall be reduced or eliminated as specified by Executive in writing delivered to Orion within five business days of Executive’s receipt of such opinion or, if Executive fails to so notify Orion, then as Orion shall reasonably determine, so that under the bases of calculations set forth in such opinion there will be no excess parachute payment. If such legal counsel so requests in connection with the opinion required by this Section, Executive and Orion shall obtain, at Orion’s expense, and the legal counsel may rely on in providing the opinion, the advice of a firm of recognized executive compensation consultants as to the reasonableness of any item of compensation to be received by Executive. Notwithstanding the foregoing, the provisions of this Section 6, including the calculations, notices and opinions provided for herein, shall be based upon the conclusive presumption that the following are reasonable: (1) the compensation and benefits provided for in Section 3 and (2) any other compensation, including but not limited to the Accrued Benefits, earned prior to the date of Executive’s Separation from Service by the Executive pursuant to the Company’s compensation programs if such payments would have been made in the future in any event, even though the timing of such payment is triggered by the

11

Change in Control or the Executive’s Separation from Service. If the provisions of Code Sections 280G and 4999 are repealed without succession, then this Section 6 shall be of no further force or effect.

7. Covenants by Executive.

(a) Confidentiality and Non-Disclosure. During Executive’s employment with the Company and for a period of two years following Executive’s Separation from Service, he or she agrees that he or she will not, except in furtherance of the business of the Company, disclose, furnish, or make available to any person or use for the benefit of himself or any other person any confidential or proprietary information or data of the Company including, but not limited to, trade secrets, customer and supplier lists, pricing policies, operational methods, marketing plans or strategies, product development techniques or plans, business acquisition or disposition plans, new personnel employment plans, methods of manufacture, technical process, and formulae, designs and design projects, inventions and research projects and financial budgets and forecasts except (i) information which at the time is available to others in the business or generally known to the public other than as a result of disclosure by Executive not permitted hereunder, and (ii) when required to do so by a court of competent jurisdiction, by any governmental agency or by any administrative, legislative or regulatory body; provided that in this instance Executive shall make reasonable efforts to inform the Company of any such request prior to any disclosure so as to permit the Company a meaningful opportunity to seek a protective order or similar adjudication. Upon termination of his employment with the Company, Executive will immediately return to the Company all written or electronically stored confidential or proprietary information in whatever format it is contained.

(b) Non-Competition/Non-Solicitation.

(i) During Executive’s employment with the Company and for a period of two years following Executive’s Separation from Service, Executive agrees not to directly or indirectly engage, or assist any business or entity, in Competitive Business Activity in any capacity, including without limitation as an employee, officer, or director of, or consultant or advisor to, any person or entity engaged directly or indirectly in a business which engages in Competitive Business Activity, in North America or anywhere that Orion or its Successor does business at the time of Executive’s termination of employment, without the written consent of the Board.

(ii) During Executive’s employment with the Company and for a period of two years following Executive’s Separation from Service, Executive agrees not to, in any form or manner, directly or indirectly, on his own behalf or in combination with others (1) solicit, induce or influence any customer, supplier, lender, lessor or any other person with a business relationship with the Company to discontinue or reduce the extent of such business relationship, or (2) recruit, solicit or otherwise induce or influence any employee of the Company to discontinue their employment with the Company.

(c) Disclosure and Assignment to the Company of Inventions and Innovations.

12

(i) Executive agrees to disclose and assign to the Company as the Company’s exclusive property, all inventions and technical or business innovations, including but not limited to all patentable and copyrightable subject matter (collectively, the “Innovations”) developed, authored or conceived by Executive solely or jointly with others during the period of Executive’s employment, including during Executive’s employment prior to the date of this Agreement, (1) that are along the lines of the business, work or investigations of the Company to which Executive’s employment relates or as to which Executive may receive information due to Executive’s employment with the Company, or (2) that result from or are suggested by any work which Executive may do for the Company or (3) that are otherwise made through the use of Company time, facilities or materials. To the extent any of the Innovations is copyrightable, each such Innovation shall be considered a “work for hire.”

(ii) Executive agrees to execute all necessary papers and otherwise provide proper assistance (at the Company’s expense), during and subsequent to Executive’s employment, to enable the Company to obtain for itself or its nominees, all right, title, and interest in and to patents, copyrights, trademarks or other legal protection for such Innovations in any and all countries.

(iii) Executive agrees to make and maintain for the Company adequate and current written records of all such Innovations;

(iv) Upon any termination of Executive’s employment, Executive agrees to deliver to the Company promptly all items which belong to the Company or which by their nature are for the use of Company employees only, including, without limitation, all written and other materials which are of a secret or confidential nature relating to the business of the Company.

(v) In the event Company is unable for any reason whatsoever to secure Executive’s signature to any lawful and necessary documents required, including those necessary for the assignment of, application for, or prosecution of any United States or foreign application for letters patent or copyright for any Innovation, Executive hereby irrevocably designates and appoints Company and its duly authorized officers and agents as Executive’s agent and attorney-in-fact, to act for and in Executive’s behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the assignment, prosecution, and issuance of letters patent or registration of copyright thereon with the same legal force and effect as if executed by Executive. Executive hereby waives and quitclaims to Company any and all claims, of any nature whatsoever, which Executive may now have or may hereafter have for infringement of any patent or copyright resulting from any such application.

(d) Remedies Not Exclusive. In the event that Executive breaches any terms of this Section 7, Executive acknowledges and agrees that said breach may result in the immediate and irreparable harm to the business and goodwill of the Company and that damages, if any, and remedies of law for such breach may be inadequate and indeterminable. The Company, upon Executive’s breach of this Section 7, shall therefore be entitled (in addition to and without limiting any other remedies that the Company may seek under this Agreement or otherwise at law or in equity) to (1) seek from any court of

13

competent jurisdiction equitable relief by way of temporary or permanent injunction and without being required to post a bond, to restrain any violation of this Section 7, and for such further relief as the court may deem just or proper in law or equity, and (2) in the event that the Company shall prevail, its reasonable attorneys fees and costs and other expenses in enforcing its rights under this Section 7.

(e) Severability of Provisions. If any restriction, limitation, or provision of this Section 7 is deemed to be unreasonable, onerous, or unduly restrictive by a court of competent jurisdiction, it shall not be stricken in its entirety and held totally void and unenforceable, but shall remain effective to the maximum extent possible within the bounds of the law. If any phrase, clause or provision of this Section 7 is declared invalid or unenforceable by a court of competent jurisdiction, such phrase, clause, or provision shall be deemed severed from this Section 7, but will not affect any other provision of this Section 7, which shall otherwise remain in full force and effect. The provisions of this Section 7 are each declared to be separate and distinct covenants by Executive.

8. Notice. Any notice, request, demand or other communication required or permitted herein will be deemed to be properly given when personally served in writing or when deposited in the United States mail, postage prepaid, addressed to Executive at the address appearing at the end of this Agreement and to the Company with attention to the Chairman of the Board of Orion and the General Counsel of Orion. Either party may change its address by written notice in accordance with this paragraph.

9. Set Off; Mitigation. The Company’s obligation to pay Executive the amounts and to provide the benefits hereunder shall be subject to set-off, counterclaim or recoupment of amounts owed by Executive to the Company. However, Executive shall not be required to mitigate the amount of any payment provided for pursuant to this Agreement by seeking other employment or otherwise.

10. Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective executors, administrators, successors and assigns. If Orion experiences a Change of Control, or otherwise sells, assigns or transfers all or substantially all of its business and assets to any person or if Orion merges into or consolidates or otherwise combines (where Orion does not survive such combination) with any person (any such event, a “Sale of Business”), then Orion shall assign all of its right, title and interest in this Agreement as of the date of such event to such person, and Orion shall cause such person, by written agreement in form and substance reasonably satisfactory to Executive, to expressly assume and agree to perform from and after the date of such assignment all of the terms, conditions and provisions imposed by this Agreement upon the Company. Failure of Orion to obtain such agreement prior to the effective date of such Sale of Business shall be a breach of this Agreement constituting “Good Reason” hereunder, except that for purposes of implementing the foregoing the date upon which such Sale of Business becomes effective shall be the Termination Date. In case of such assignment by Orion and of assumption and agreement by such person, as used in this Agreement, “Orion” shall thereafter mean the person which executes and delivers the agreement provided for in this Section 10 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of law, and this Agreement shall inure to the benefit of, and be enforceable by, such person. Executive shall, in his discretion, be entitled to proceed against any or all of such persons, any person which theretofore was such a successor to Orion, and Orion (as so defined) in any action to enforce any rights of Executive hereunder. Except as provided in this Section 10, this Agreement shall not be assignable by

14

Orion. This Agreement shall not be terminated by the voluntary or involuntary dissolution of Orion.

11. Arbitration. Any controversy or claim arising out of or relating to this Agreement or the breach of this Agreement that cannot be mutually resolved by the Executive and the Company, including any dispute as to the calculation of the Executive’s Benefits, Base Salary, Bonus Amount or any Severance Payment hereunder, shall be submitted to arbitration in Milwaukee, Wisconsin, in accordance with the procedures of the American Arbitration Association. The determination of the arbitrator shall be conclusive and binding on the Company and the Executive, and judgment may be entered on the arbitrator’s award in any court having jurisdiction.

12. Applicable Law and Jurisdiction. This Agreement is to be governed by and construed under the laws of the United States and of the State of Wisconsin without resort to Wisconsin’s choice of law rules. Each party hereby agrees that the forum and venue for any legal or equitable action or proceeding arising out of, or in connection with, this Agreement will lie in the appropriate federal or state courts in the State of Wisconsin and specifically waives any and all objections to such jurisdiction and venue.

13. Captions and Paragraph Headings. Captions and paragraph headings used herein are for convenience only and are not a part of this Agreement and will not be used in construing it.

14. Invalid Provisions. Subject to Section 7(e), should any provision of this Agreement for any reason be declared invalid, void, or unenforceable by a court of competent jurisdiction, the validity and binding effect of any remaining portion will not be affected, and the remaining portions of this Agreement will remain in full force and effect as if this Agreement had been executed with said provision eliminated.

15. No Waiver. The failure of a party to insist upon strict adherence to any term of this Agreement on any occasion shall not be considered a waiver of such party’s rights or deprive such party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement.

16. Entire Agreement. This Agreement contains the entire agreement of the parties with respect to the subject matter of this Agreement except where other agreements are specifically noted, adopted, or incorporated by reference. This Agreement otherwise supersedes any and all other agreements (including the Executive’s prior Executive and Severance Agreement and, with respect to the definition of Cause and the process for Cause termination, any stock option or similar equity award agreements with the Company to which Executive may now or hereafter be a party), either oral or in writing, between the parties hereto with respect to the employment of Executive by Company, and all such agreements shall be void and of no effect. Each party to this Agreement acknowledges that no representations, inducements, promises, or agreements, oral or otherwise, have been made by any party, or anyone acting on behalf of any party, which are not embodied herein, and that no other agreement, statement, or promise not contained in this Agreement will be valid or binding.

17. Modification. This Agreement may not be modified or amended by oral agreement, but only by an agreement in writing signed by Orion and Executive.

15

18. Counterparts. This Agreement may be signed in counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument.

IN WITNESS WHEREOF, this Agreement is effective as of September 27, 2012.
