(a)If Executive’s employment hereunder shall terminate at the expiration of the term provided in Section 3.1 because Executive provided written notice of non-renewal to the Company, for any reason described in Section ‎0,  ‎0, or ‎0 or pursuant to Executive’s resignation for other than Good Reason, then all compensation and all benefits to Executive hereunder shall terminate contemporaneously with such termination of employment, except that Executive’s equity incentive awards shall be governed by the terms thereof (subject to clause (v) below) and Executive shall be entitled to (i) payment of all accrued and unpaid Base Salary to the Date of Termination (or, to the extent specifically provided in Section 3.3, to the Specified Date of Termination),  (ii) reimbursement for all incurred but unreimbursed expenses for which Executive is entitled to reimbursement in accordance with Section ‎0,  (iii) payment of all accrued and unused paid vacation for the calendar year in which the Date of Termination occurs, (iv) benefits to which Executive is entitled under the terms of any applicable benefit plan or program,  (v) if such termination is a result of Executive’s resignation for other than Good Reason and if the Company required a Date of Termination prior to the Specified Date of Termination pursuant to Section 3.3, then the Company shall cause all stock options and other equity-based incentive awards, if any, awarded to Executive by the Company that become vested based solely on continued employment to have the same vesting status as of the Date of Termination as Executive would have achieved under the terms of such awards had Executive remained continuously employed by the Company until the Specified Date of Termination, and (vi) if, on the Date of Termination, the Company does not have a right to terminate Executive’s employment under Section 3.2(c), any unpaid Annual Bonus for the calendar year ending on or prior to the Date of Termination (or, to the extent specifically provided in Section 3.3, ending on or prior to the Specified Date of Termination), which amount shall be payable in a lump-sum on the date such annual bonuses are paid to executives who have continued employment with the Company (provided, however, that if Executive is a specified employee (as such term is defined in section 409A of the Code and as determined by the Company in accordance with any method permitted under section 409A of the Code (a “Specified Employee”)) and the payment of the amount described in this clause (vi) would be subject to additional taxes and interest under section 409A of the Code because the timing of such payment is not delayed as provided in section 409A(a)(2)(B)(i) of the Code and the regulations thereunder, then such amount (together with interest on a non-compounded basis, from the date such payment would have been made had this payment delay not applied to the actual date of payment, at the prime rate of interest announced by

12

Wells Fargo Bank, National Association (or any successor thereto) at its principal office in Charlotte, North Carolina on the date of Executive’s termination of employment (or the first business day following such date if such termination does not occur on a business day) (the “Applicable Rate”)) shall be paid within five business days after the Section 409A Payment Date). 

(b)If Executive’s employment hereunder shall terminate at expiration of the term provided in Section 3.1 because the Company provided written notice of non-renewal to Executive,  pursuant to Executive’s resignation for Good Reason or by action of the Company pursuant to Section ‎0 for any reason other than those encompassed by Section ‎0,  ‎0, or ‎0, then all compensation and all benefits to Executive hereunder shall terminate contemporaneously with such termination of employment, except that Executive’s equity incentive awards shall be governed by the terms thereof and (i)  Executive shall be entitled to receive the compensation and benefits described in clauses Error! Reference source not found. through (iv) of Section ‎0, (ii) if, on the Date of Termination, the Company does not have a right to terminate Executive’s employment under Section 3.2(c), Executive shall be entitled to receive the compensation described in clause (vi) of Section 7.1(a), and (iii)   if, on the Date of Termination, the Company does not have a right to terminate Executive’s employment under Section ‎0,  ‎0, or ‎0 and subject to Executive’s delivery, within 50 days after the Date of Termination, and non-revocation of an executed release substantially in the form of the release contained at Appendix B (the “Release”), Executive shall receive the following additional compensation and benefits from the Company:

(A)the Company shall pay to Executive a bonus for the calendar year in which the Date of Termination occurs in an amount equal to the Annual Bonus for such year as determined in good faith by the Board in accordance with the criteria established pursuant to Section ‎0 and based on the Company’s performance for such year, which amount shall be prorated through and including the Date of Termination (based on the ratio of the number of days Executive was employed by the Company during such year (or, to the extent specifically provided in Section 3.3, the number of days Executive would have been employed by the Company during such year as of the Specified Date of Termination) to the number of days in such year), payable in a lump-sum on or before the date such annual bonuses are paid to executives who have continued employment with the Company (but in no event earlier than 60 days after the Date of Termination nor later than the June 30 next following such calendar year); provided, however, that if Executive is a Specified Employee and the payment of the amount described in this clause (A) would be subject to additional taxes and interest under section 409A of the Code because the timing of such payment is not delayed as provided in section 409A(a)(2)(B)(i) of the Code and the regulations thereunder, then such amount (together with interest on a non-compounded basis, from the date such payment would have been made had this payment delay not applied to the actual date of payment, at the Applicable Rate) shall be paid within five business days after the Section 409A Payment Date;

(B)the Company shall pay to Executive an amount equal to the Severance Multiple times the sum of (i) Executive’s Base Salary as of the Date of

13

Termination and (ii) 60% of Executive’s Base Salary as of the Date of Termination, which amount shall be paid in a lump sum payment on the date that is 60 days after the Date of Termination occurs; and

(C)during the portion, if any, of the 18-month period following the Date of Termination that Executive elects to continue coverage for Executive and Executive’s spouse and eligible dependents, if any, under the Company’s group health plans under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (COBRA), and/or sections 601 through 608 of the Employee Retirement Income Security Act of 1974, as amended, the Company shall promptly reimburse Executive on a monthly basis for the difference between the amount Executive pays to effect and continue such coverage and the employee contribution amount that active senior executive employees of the Company pay for the same or similar coverage under such group health plans.  Notwithstanding the preceding provisions of this clause (C), if the provision of the benefit described in such clause cannot be provided in the manner described in such clause without penalty, tax or other adverse impact on the Company, then the Company and Executive shall negotiate in good faith to determine an alternative manner in which the Company may provide a substantially equivalent benefit to Executive without such adverse impact on the Company.

8.2Non-Competition; Non-Solicitation.  Executive and the Company agree to the non-competition and non-solicitation provisions of this ‎0 in consideration for the Confidential Information provided by the Company to Executive pursuant to Article V of this Agreement, to protect the trade secrets and confidential information of the Company or its affiliates disclosed or entrusted to Executive by the Company or its affiliates or created or developed by Executive for the Company or its affiliates, to protect the business goodwill of the Company or its affiliates developed through the efforts of Executive and/or the business opportunities disclosed or entrusted to Executive by the Company or its affiliates and as an additional incentive for the Company to enter into this Agreement.    

(a)Subject to the exceptions set forth in Section ‎0 below, Executive expressly covenants and agrees that during the Prohibited Period (i) Executive will refrain from carrying on or engaging in, directly or indirectly, any Competing Business in the Restricted Area (excluding hiring, engaging or paying a Competing Business as a contractor or subcontractor for services) and (ii) Executive will not, and Executive will cause Executive’s affiliates not to, directly or indirectly, own, manage, operate, join, become an employee of, partner in, owner or member of (or an independent contractor to), control or participate in, be connected with or loan money to, sell or lease equipment or property to, or otherwise be affiliated with any business, individual, partnership, firm, corporation or other entity which engages in a Competing Business in the Restricted Area, as Executive expressly agrees that each of the foregoing activities would represent carrying on or engaging in a Competitive Business, as prohibited by this Section 8.2(a).

(b)Notwithstanding the restrictions contained in Section ‎0: (i) Executive or any of Executive’s affiliates may own an aggregate of not more than 2% of the outstanding stock of any class of any corporation engaged in a Competing Business, if such stock is listed on a national securities exchange or regularly traded in the over-the-counter market

15

by a member of a national securities exchange, without violating the provisions of Section ‎0, provided that neither Executive nor any of Executive’s affiliates has the power, directly or indirectly, to control or direct the management or affairs of any such corporation and is not involved in the management of such corporation (except to the extent permitted in clause (ii) of this sentence); and (ii) Executive may serve in a senior executive or director capacity for a corporation which (directly or through its subsidiaries) is engaged in a Competing Business, without violating the provisions Section ‎0, provided that the revenues attributable to such Competing Business for the four fiscal quarters of such corporation ending on or before the date of the commencement of Executive’s service in such capacity comprise less than 10% of the consolidated total revenue of such corporation for such four fiscal quarters.

(c)Executive further expressly covenants and agrees that during the Prohibited Period, Executive will not, and Executive will cause Executive’s affiliates not to (i) engage or employ, solicit or contact with a view to the engagement or employment of, or recommend or refer to any person or entity (other than the Company or one of its affiliates) for engagement or employment any person who is an officer or employee of the Company or any of its affiliates or (ii) canvass, solicit, approach or entice away or cause to be canvassed, solicited, approached or enticed away from the Company or any of its affiliates any person  or entity who or which is a customer of any of such entities during the period during which Executive is employed by the Company. 

(d)The restrictions contained in Section ‎0 shall not apply to any product or service that the Company provided during Executive’s employment but that the Company no longer provides at the Date of Termination.  Further, notwithstanding the other provisions of this Section 8.2, within the State of Oklahoma, the restrictions of Sections 8.2(a) and 8.2(c)(ii) shall be limited to preventing Executive from directly soliciting the sale of goods, services or a combination of goods and services from any established customer of the Company, as may exist from time-to-time.  

(e)Before accepting employment with any other person or entity while employed by the Company or during the Prohibited Period, the Executive will inform such person or entity of the restrictions contained in this Article VIII.

8.3Relief.  Executive and the Company agree and acknowledge that the limitations as to time, geographical area and scope of activity to be restrained as set forth in Section ‎0 are reasonable and do not impose any greater restraint than is necessary to protect the legitimate business interests of the Company.  Executive and the Company also acknowledge that money damages would not be sufficient remedy for any breach of this ‎0 by Executive, and the Company or its affiliates shall be entitled to enforce the provisions of this ‎0 by terminating payments then owing to Executive under this Agreement or otherwise and to specific performance and injunctive relief as remedies for such breach or any threatened breach.  Such remedies shall not be deemed the exclusive remedies for a breach of this ‎0 but shall be in addition to all remedies available at law or in equity, including the recovery of damages from Executive and Executive’s agents. However, if it is determined that Executive has not committed a breach of this ‎0, then the Company shall resume the payments and benefits due under this Agreement and promptly pay to Executive all payments (together with interest on a non-compounded basis, from the date each such payment

16

would have been made had such payment not been suspended to the actual date of payment, at the Applicable Rate) and benefits that had been suspended pending such determination.

8.4Reasonableness; Enforcement.  Executive hereby represents to the Company that Executive has read and understands, and agrees to be bound by, the terms of this ‎0.  Executive acknowledges that the geographic scope and duration of the covenants contained in this ‎0 are the result of arm’s-length bargaining and are fair and reasonable in light of (a) the nature and wide geographic scope of the operations of the Business, (b) Executive’s level of control over and contact with the Business in all jurisdictions in which it is conducted, (c) the fact that the Business is conducted throughout the Restricted Area and (d)the amount of Confidential Information that Executive is receiving in connection with the performance of Executive’s duties hereunder.  It is the desire and intent of the parties that the provisions of this ‎0 be enforced to the fullest extent permitted under applicable Legal Requirements, whether now or hereafter in effect and therefore, to the extent permitted by applicable Legal Requirements, Executive and the Company hereby waive any provision of applicable Legal Requirements that would render any provision of this ‎0 invalid or unenforceable.

8.5Reformation.   The Company and Executive agree that the foregoing restrictions are reasonable under the circumstances and that any breach of the covenants contained in this ‎0 would cause irreparable injury to the Company.  Executive understands that the foregoing restrictions may limit Executive’s ability to engage in certain businesses anywhere in the Restricted Area during the Prohibited Period, but acknowledges that Executive will receive sufficient consideration from the Company to justify such restriction.  Further, Executive acknowledges that Executive’s skills are such that Executive can be gainfully employed in non-competitive employment, and that the agreement not to compete will not prevent Executive from earning a living.  Nevertheless, if any of the aforesaid restrictions are found by a court of competent jurisdiction to be unreasonable, or overly broad as to geographic area or time, or otherwise unenforceable, the parties intend for the restrictions herein set forth to be modified by the court making such determination so as to be reasonable and enforceable and, as so modified, to be fully enforced.  By agreeing to this contractual modification prospectively at this time, the Company and Executive intend to make this provision enforceable under the law or laws of all applicable States, Provinces and other jurisdictions so that the entire agreement not to compete and this Agreement as prospectively modified shall remain in full force and effect and shall not be rendered void or illegal.  Such modification shall not affect the payments made to Executive under this Agreement.

ARTICLE IX

DISPUTE RESOLUTION

9.1Arbitration.  All claims or disputes between Executive and the Company or its parents, subsidiaries and affiliates (including, without limitation, claims relating to the validity, scope, and enforceability of this ‎0 and claims arising under any federal, state or local law regarding the terms and conditions of employment or prohibiting discrimination in employment or governing the employment relationship in any way) shall be submitted for final and binding arbitration in Houston, Texas in accordance with the then-applicable rules for resolution of employment disputes of the American Arbitration Association (“AAA”).  The arbitration shall be conducted by a single arbitrator chosen pursuant to the then-applicable rules for resolution of employment disputes of

17

the AAA, and the Company shall bear the costs of such arbitration.  For the avoidance of doubt, the Company’s assumption of costs referenced in the previous sentence applies to the costs of the AAA only, and does not include attorney or expert fees or other fees or costs incurred by Executive.  The arbitrator shall apply the substantive law of the State of Texas (excluding Texas choice-of-law principles that might call for the application of some other state’s law), or federal law, or both as applicable to the claims asserted.  The results of the arbitration and the decision of the arbitrator will be final and binding on the parties and each party agrees and acknowledges that these results shall be enforceable in a court of law.    No demand for arbitration may be made after the date when the institution of legal or equitable proceedings based on such claim or dispute would be barred by the applicable statute(s) of limitations.  In the event either party must resort to the judicial process to enforce the provisions of this Agreement, the award of an arbitrator or equitable relief granted by an arbitrator, the party successfully seeking enforcement shall be entitled to recover from the other party all costs of such litigation including, but not limited to, reasonable attorneys fees and court costs.    To the fullest extent permitted by law, all proceedings conducted pursuant to this agreement to arbitrate, including any order, decision or award of the arbitrator, shall be kept confidential by all parties. Notwithstanding the foregoing, Executive and the Company further acknowledge and agree that a court of competent jurisdiction residing in Houston, Texas shall have the power to maintain the status quo pending the arbitration of any dispute under this ‎0, and this ‎0 shall not require the arbitration of any application for emergency, temporary or preliminary injunctive relief (including temporary restraining orders) by either party pending arbitration, including, without limitation, any application for emergency, temporary or preliminary injunctive relief for any claim arising out of Article V or Article VIII of this Agreement; provided, however, that the remainder of any such dispute beyond the application for such emergency, temporary or preliminary injunctive relief shall be subject to arbitration under this ‎0.    THE PARTIES ACKNOWLEDGE THAT, BY SIGNING THIS AGREEMENT, THEY ARE KNOWINGLY AND VOLUNTARILY WAIVING ANY RIGHTS THAT THEY MAY HAVE TO A JURY TRIAL OR, EXCEPT AS EXPRESSLY PROVIDED HEREIN, A  COURT TRIAL OF ANY CLAIM THAT IS SUBJECT TO THIS ARTICLE IX.

ARTICLE X

CERTAIN EXCISE TAXES

10.1Certain Excise Taxes.   Notwithstanding anything to the contrary in this Agreement, if Executive is a “disqualified individual” (as defined in section 280G(c) of the Code), and the payments and benefits provided for in this Agreement, together with any other payments and benefits which Executive has the right to receive from the Company or any of its affiliates, would constitute a “parachute payment” (as defined in section 280G(b)(2) of the Code), then the payments and benefits provided for in this Agreement shall be either (a) reduced (but not below zero) so that the present value of such total amounts and benefits received by Executive from the Company and its affiliates will be one dollar ($1.00) less than three times Executive’s “base amount” (as defined in section 280G(b)(3) of the Code) and so that no portion of such amounts and benefits received by Executive shall be subject to the excise tax imposed by section 4999 of the Code or (b) paid in full, whichever produces the better net after-tax position to Executive (taking into account any applicable excise tax under section 4999 of the Code and any other applicable taxes).  The reduction of payments and benefits hereunder, if applicable, shall be made by reducing, first, payments or benefits to be paid in cash hereunder in the order in which such

18

payment or benefit would be paid or provided (beginning with such payment or benefit that would be made last in time and continuing, to the extent necessary, through to such payment or benefit that would be made first in time) and, then, reducing any benefit to be provided in-kind hereunder in a similar order.  The determination as to whether any such reduction in the amount of the payments and benefits provided hereunder is necessary shall be made by the Company in good faith.  If a reduced payment or benefit is made or provided and through error or otherwise that payment or benefit, when aggregated with other payments and benefits from the Company (or its affiliates) used in determining if a “parachute payment” exists, exceeds one dollar ($1.00) less than three times Executive’s base amount, then Executive shall immediately repay such excess to the Company upon notification that an overpayment has been made.  Nothing in this Section 10.1 shall require the Company to be responsible for, or have any liability or obligation with respect to, Executive’s excise tax liabilities under section 4999 of the Code.    Notwithstanding the foregoing, if shareholder approval (obtained in a manner that satisfies the requirements of section 280G(b)(5) of the Code) of a payment or benefit to be provided to Executive by the Company or any other person (whether under this Agreement or otherwise) would prevent Executive from receiving a “parachute payment” (as defined in section 280G(b)(2) of the Code), then, upon the request of Executive and his agreement (to the extent necessary) to subject his entitlement to the receipt of such payment or benefit to shareholder approval, the Company shall seek such approval in a manner that satisfies the requirements of section 280G of the Code and the regulations thereunder.

This Release Agreement (this “Agreement”) constitutes the release referred to in that certain Employment Agreement (the “Employment Agreement”) dated as of April __, 2012, by and between David J. Nightingale (“Executive”) and Rockwater Energy Solutions, Inc. (the “Company”).

1.General Release.

(a)For good and valuable consideration, including the Company’s provision of certain payments and benefits to Executive in accordance with Section 7.1(b)(iii) of the Employment Agreement, Executive hereby releases, discharges and forever acquits the Company, its affiliates and subsidiaries, the past, present and future stockholders, members, partners, directors, managers, employees, agents, attorneys, heirs, legal representatives, successors and assigns of the foregoing, as well as all employee benefit plans maintained by the Company or any of its affiliates or subsidiaries and all fiduciaries and administrators of any such plan, in their personal and representative capacities (collectively, the “Company Parties”), from liability for, and hereby waives, any and all claims, rights, damages, or causes of action of any kind related to Executive’s employment with any Company Party, the termination of such employment, and any other acts or omissions related to any matter on or prior to the date of this Agreement (collectively, the “Released Claims”).

(c)In no event shall the Released Claims include (i) any claim which arises after the date of this Agreement, (ii) any claims for the payments and benefits payable to Executive under Section 7.1(b) of the Employment Agreement, (iii) any claims to the equity interests in the Company Parties that Executive holds as of the date of this Agreement which remain subject to

B-1

the terms and conditions, as applicable, of the Company’s stockholders agreement (as may be amended from time to time) and any specific equity award agreement between Executive and a Company Party,  and (iv) any claim for or right to indemnification under the policies or governing instruments of the Company Parties and for coverage under any directors and officers liability insurance policies maintained by the Company Parties.
