VOLUNTARY RETIREMENT AGREEMENT AND GENERAL RELEASE

Exhibit 10.1

VOLUNTARY RETIREMENT AGREEMENT AND GENERAL RELEASE

THIS VOLUNTARY RETIREMENT AGREEMENT AND GENERAL RELEASE (“Agreement”) is by and between Sanchez Oil and Gas Corporation, a Delaware corporation (“Company”), Sanchez Energy Corporation, a Delaware corporation (“SN” and together with the Company, the “Sanchez Companies”), and Michael G. Long (“Executive”) an individual.

RECITALS:

A.                                    The Company and Executive agree to terminate the employment relationship between them;

B.                                    Executive agrees to settle and release any and all actual or potential claims of Executive against the Sanchez Companies arising out of or in connection with the service or employment of Executive with the Sanchez Companies, the terms and conditions of Executive’s service or employment, the termination of such service or employment, and any other action, event, or matter prior to the date of this Agreement; and

C.                                    Executive has substantial knowledge of the Sanchez Companies’ operations, customers, vendors, suppliers, and other proprietary and confidential information belonging to the Sanchez Companies, and the Sanchez Company desire to protect such information from disclosure by Executive.

NOW THEREFORE, in consideration of the mutual promises and covenants contained herein and for other good and valuable consideration, the parties agree as follows:

1.                                      Voluntary Retirement.  This Agreement evidences the Executive’s voluntary retirement from the Company and as an officer of SN.  Effective as of a date to be mutually determined by the Company and the Executive, but no later than May 31, 2015, (the “Retirement Date”) the Executive shall retire from his position as an employee of the Company and resign all officer positions with the Sanchez Companies and their respective affiliates.

2.                                      Compensation.  In consideration for executing this Agreement, and complying with its terms, the Sanchez Companies agree to pay Executive the following severance payments (collectively the “Severance Payments”):

a.                                      Prorated Bonus.  Within 10 days of the execution of this Agreement by the Executive (the “Effective Date”), and the determination of the Retirement Date, the Executive shall receive a lump-sum cash payment (less required payroll withholdings) equal to the sum of (a) $50,000 and (b) the product of:

(i)                                     90% of the Executive’s annual base salary immediately prior to the Effective Date; and

(ii)                                  a fraction, the numerator of which is the number of days in calendar 2015 through the Retirement Date and the denominator of which is 365.

An example of how the Prorated Bonus would be calculated without regard to payroll withholdings, assuming a Retirement Date of April 30, 2015 and annual base salary of $450,000, is as follows: $50,000 +  (($450,000 *.90) * (120/365))  = $183,150.67.

The Executive will not be eligible for any other bonus payments with respect to the 2015 calendar year, or any subsequent calendar year.

b.                                      Medical Continuation.  Upon retirement the Executive and his dependents currently receiving group health, vision, and dental plan coverage will be given the opportunity to elect continuation of coverage at their current elections under the Company’s group health, vision, and dental plan in accordance with the applicable plan terms and as required by Section 4890B of the Internal Revenue Code (“COBRA”).  For a period of 18 months after the Retirement Date, the Company will pay the normal COBRA premium charged by the Company for such continuation coverage, less the amount of any contribution required for similarly situated active employees.

c.                                       Restricted Stock Awards:  Upon retirement, and the subsequent execution of the  Waiver and Release attached hereto as Exhibit “A” and the expiration of its seven (7) day revocation period without revocation, the Executive’s outstanding awards of restricted stock will be amended to become fully vested.

d.                                      Executive acknowledges and agrees that the Sanchez Companies have no legal obligation to pay these Severance Payments and do so only in exchange for the promises provided in this Agreement.  The Sanchez Companies’ obligations to make any payments otherwise due under the Agreement shall cease in the event the Executive fails to comply with the terms of this Agreement or the Waiver and Release attached as Exhibit “A”.

3.                                      Sufficient Consideration.  Executive acknowledges that the Severance Payments constitute sufficient consideration for Executive’s promises and commitments hereunder and are in addition to any amounts to which Executive already was entitled.

4.                                      Release and Transition Services.  In return for the Severance Payments, Executive hereby releases and forever discharges the Sanchez Companies, and their predecessors, successors, affiliates, directors and officers, employees and agents, insurers, employee benefit plans and the fiduciaries and agents of said plans (collectively

2

the “Releasees”), from any and all claims which Executive had, now has, or may thereafter claim to have had or discover arising from Executive’s application, hiring, employment, compensation, services, or termination of employment by the Sanchez Companies or Releasees.  These claims include, but are not limited to: (a) any and all claims based upon unpaid wages or other compensation; (b) any and all claims based on violations of Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1991, the Americans with Disabilities Act, the Age Discrimination in Employment Act, the Employee Retirement Income Security Act, the Family and Medical Leave Act, the Equal Pay Act, the Older Worker’s Benefit Protection Act, Title 42 U.S.C. § 1981, claims in connection with workers’ compensation or “whistle blower” statutes; the Energy Reorganization Act, as amended, 42 U.S.C. §§ 5851, the Sarbanes-Oxley Act of 2002, and the Pregnancy Discrimination Act; (c) any and all claims under Texas statutory or common law, including but not limited to claims brought under the Texas Commission on Human Rights Act, The Texas Pay Day Law, claims for employment discrimination or harassment, wrongful discharge, or breach of public policy; and (d) any and all claims under state, federal, or common law relating to wrongful discharge, discrimination, harassment, including but not limited to breach of express or implied contract, promissory estoppel, emotional distress, defamation, invasion of privacy rights, fraud, or misrepresentation.  Executive intends this Release to be as broad and comprehensive as possible so that the Releasees shall never be liable, directly or indirectly, to the Executive for any claims, demands, actions, or causes of action of whatsoever nature or character released herein; provided, however, that this release shall not apply to (1) any existing right Executive has to indemnification, contribution, or right to require a defense from the Sanchez Companies; (2) any directors and officers and general liability insurance coverage; (3) any rights Executive may have as a shareholder of the Sanchez Companies; and (4) any rights which cannot be waived or released as a matter of law.

By signing this Agreement, Executive acknowledges that he has not filed any complaints, charges, or claims for relief against any of the Releasees with any local, state, or federal court or administrative agency.  It is further understood, acknowledged, and agreed by the Executive that nothing in this Agreement shall interfere with any of the Executive’s rights to file a charge, cooperate, or participate in an investigation or proceeding conducted by the Equal Employment Opportunity Commission, or other federal or state regulatory or law enforcement agency.  However, the consideration provided to the Executive in accordance with this Agreement shall be the sole relief provided for any claims released herein, and the Executive shall not be entitled to recover and agrees to waive any monetary benefits or recovery against the Releasees in connection with any such claim, charge, or proceeding without regard to who has brought such claim, charge, or proceeding.

In return for the Severance Payments and in addition to the foregoing releases, Executive agrees to serve as a consultant in connection with providing the Sanchez Companies with assistance and consultation as reasonably requested and for a period of one year from the date of this Agreement with respect to the transitioning of his role as Chief Financial Officer of SN to both his interim successor (currently contemplated to be Mr. Gleeson Van Riet) and his ultimate successor to be identified by SN.  In this regard,

Executive agrees to be reasonably available at reasonable times to provide limited assistance to such successors in their transition to Chief Financial Officer of SN.

5.                                      The Age Discrimination In Employment Act.  Executive specifically understands and acknowledges that the Age Discrimination in Employment Act of 1967, as amended, provides Executive the right to bring a claim against the Sanchez Companies if Executive believes that he/she has been discriminated against on the basis of age.  Executive understands the rights afforded under this Act and agrees that Executive shall not file any claim or action against the Releasees based on any alleged violation(s) of the Age Discrimination in Employment Act, based on acts, omissions or events occurring on or prior to the Effective Date of this Agreement.  Executive hereby waives any right to assert a claim for relief available under the Age Discrimination in Employment Act, including, but not limited to, back pay, attorneys’ fees, damages, lost benefits, reinstatement, or injunctive relief for any act or omission by the Releasees up through the Effective Date of this Agreement.

6.                                      Non-Competition.  In exchange for the Severance Payments and the confidential information the Executive will be provided and/or have access to after the Effective Date but prior to the Retirement Date, which Executive acknowledges constitutes good and valuable consideration, Executive agrees that for a period of twelve (12) months commencing on the Retirement Date (the “Non-Competition Period”), Executive shall not, directly or indirectly, without the prior written permission of the  Sanchez Companies:
