On behalf of the several Agents (as defined herein)

Ladies and Gentlemen:

Sanchez Energy Corporation, a corporation organized under the laws of the State of Delaware (the “Company”), proposes to issue and sell to certain investors (collectively, the “Investors” and each an “Investor”) that are both QIBs (as that term is used in Rule 144A under the Act (as defined below)) and accredited investors (as that term is used in Regulation D under the Act) up to $250 million aggregate liquidation preference of the Company’s Cumulative Perpetual Convertible Preferred Stock, Series B (the “Securities”), which will be convertible into shares of the Company’s common stock, par value $0.01 per share (the “Underlying Securities”), on such pricing terms as will be set forth in a final term sheet dated on or about the date hereof (the “Final Term Sheet”).

The Securities will be offered and sold to the Investors without being registered under the Securities Act of 1933, as amended (the “Act”), in reliance on exemptions therefrom.

In connection with the sale of the Securities, the Company has prepared a preliminary private placement memorandum relating to the Securities and the terms of the offering (the “Preliminary Memorandum”), and will prepare the Final Term Sheet and a final private placement memorandum relating to the Securities and the final pricing terms of the offering (the “Final Memorandum”).  In addition, the Company has prepared an investor presentation dated March 2013 (the “Investor Presentation”) and the risk factors (“Risk Factors”) set forth in the Purchase Agreements (as defined herein), which information together with the Exchange Act Filings (as defined herein), have been made available to the Investors along with the Preliminary Memorandum and, on the date hereof, the Final Term Sheet, and prior to the Closing Date (as defined herein), the Final Memorandum.

1.                             Agreement to Act as Agent; Placement of Securities.

(a)          Subject to the terms and conditions herein set forth, the Company appoints RBC Capital Markets, LLC, as the Company’s exclusive placement agent (in such capacity, the “Placement Agent”), on behalf of itself and the other agents named on Schedule I hereto (together with the Placement Agent, the “Agents” and each an

“Agent”), on a reasonable best efforts basis, in connection with the issuance and sale by the Company of the Securities to the Investors and each of the Agents severally agrees, subject to the representations, warranties and agreements herein set forth, to so act.

(b)         This Agreement is not a commitment, express or implied, on the part of the Agents to commit any capital.  Under no circumstances will any Agent be obligated to purchase any Securities for its own account.  In soliciting purchases of Securities, the Agents shall act solely as the Company’s agents and not as principals and therefore the Agents shall have no authority to bind the Company.  Each Agent may retain other brokers or dealers to act as sub-agents on its behalf in connection with the offering and sale of the Securities.

(c)          The purchases of the Securities by the Investors shall be evidenced by the execution and delivery of securities purchase agreements, which (1) in the case of Investors who sign purchase agreements in connection with the pricing of the Securities (including such Investors who subsequently increase their commitments thereunder following the pricing of the Securities by delivering amended signature pages thereto as contemplated thereby), shall be substantially in the form of Exhibit A-1 (the “Signed Investor Purchase Agreements”), and (2) in the case of other Investors who sign purchase agreements following the pricing of the Securities, shall be substantially in the form of Exhibit A-2 (the “Additional Investor Purchase Agreements” and together with the Signed Investor Purchase Agreements, collectively, the “Purchase Agreements”), which such Purchase Agreements shall become valid and binding agreements (severally and not jointly) between each respective Investor and the Company upon confirmation and acceptance by such Investors and the Company of the Final Term Sheet and final allocations of Securities to such Investors.

(d)         The Company and U.S. Bank National Association, as escrow agent (“Escrow Agent”), has entered into an Escrow Agreement (the “Escrow Agreement”), pursuant to which an escrow account will be established, at the Company’s expense, for the benefit of the Company and the Investors (the “Escrow Account”).  Prior to the Closing Date (as defined herein), each Investor will deposit in the Escrow Account the full amount of the purchase price for the Securities being purchased by such Investor (the “Escrow Funds”), except for Investors that are registered investment companies under the Investment Company Act of 1940, as amended, for which alternative arrangements have been made under the Purchase Agreements (the “Alternative Arrangements”).

(e)          As compensation for services rendered prior to and as of the Closing Date, the Company shall pay to the Agents an aggregate fee equal to 3.50% of the aggregate gross proceeds received by the Company on the Closing Date from the sale of the Securities (the “Placement Fee”), such Placement Fee to be divided among the Agents according to the corresponding percentages for the Agents as set forth on Schedule I hereto; provided that if the aggregate gross proceeds from the offer and sale of all Securities to be offered and sold to Investors pursuant to the Purchase Agreements exceeds $175 million, the Placement Agent shall receive 100% of the Placement Fee attributable to such excess amount received by the Company. The Placement Fee shall be

2

payable by Federal Funds wire transfer to an account or accounts designated by RBC Capital Markets, LLC on behalf of all Agents.

(f)            No Securities that the Company has agreed to sell pursuant to the Purchase Agreements shall be deemed to have been purchased and paid for, or sold by the Company, until such Securities shall have been delivered to the applicable Investor (or its authorized agent) against payment by such Investor (or its authorized agent) or irrevocably deposited with the facilities of The Depository Trust Company through Continental Stock Transfer & Trust Company (the “Transfer Agent”) against payment therefor pursuant to Section 4 hereof.  If the Company shall default in its obligations to deliver Securities to an Investor (or its authorized agent) whose offer it has accepted, and from which it has received payment for such Securities, the Company agrees to indemnify and hold harmless the Agent Entities (as defined herein) against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject which arise out of or are based upon such default of the Company; provided that the Company shall have no such obligations in the event an Investor fails to follow the procedures set forth in the Purchase Agreement with respect to such Investor for acceptance of the Securities and such failure is the cause of such default.

(g)         The Company acknowledges and agrees that each Agent has been retained to act solely as agent to the Company, and not in any capacity for any other person, and the Company’s engagement of each Agent is not intended to confer rights upon any person (including shareholders, employees or creditors of the Company) not a party hereto as against any Agent or its affiliates, or their respective directors, officers, employees or agents, successors, or assigns.  Each Agent shall act as an independent contractor under this Agreement, and not in any other capacity including as a fiduciary, and any obligations arising out of its engagement shall be owed solely to the Company.

2.                             Representations and Warranties of the Company.  The Company represents and warrants to, and agrees with each Agent as set forth below in this Section 2.

14

8.          Indemnification and Contribution.

(a)   The Company agrees to indemnify and hold harmless each Agent, each person, if any, who controls such Agent within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, and each affiliate of such Agent within the meaning of Rule 405 under the Act (“Agent Entities”) from and against any and all losses, claims, damages and liabilities arising out of or in connection with the transactions contemplated by this Agreement, or any claim, litigation, investigation or proceedings relating to the foregoing, regardless of whether any such Agent Entity or any such other person is a party thereto (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Memorandum, the Final Term Sheet or the Final Memorandum, in any amendment thereof or supplement thereto, or in the Company’s Exchange Act Filings (taken together with the Investor Presentation and the applicable Risk Factors), or caused by any omission or alleged omission to state therein a material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading.

(b)   In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a), such person (the “indemnified party”) shall promptly notify the Company in writing and the Company, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the Company may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the Company and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the Company and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the Company shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by RBC Capital Markets, LLC. The Company shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Company agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested the Company to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the Company agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by the Company of the aforesaid request, (ii)

15

the Company shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ notice of its intention to settle.  The Company shall not, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(c)   To the extent the indemnification provided for in Section 8(a) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then the Company, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the applicable Agent on the other hand from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company on the one hand and of such Agent on the other hand, and other equitable considerations. The relative benefits received by the Company on the one hand and an Agent on the other hand in connection with the offering of the Securities shall be deemed to be in the same proportion as (i) the total value received or proposed to be received by the Company pursuant to any sale of the Securities (whether or not consummated) bears to (ii) the fee paid or proposed to be paid to such Agent in connection with such sale. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(d)   The Company agrees that no indemnified party shall have any liability to the Company or any person asserting claims on behalf of or in right of the Company in connection with or as a result of any Agent’s engagement under this Agreement or any matter referred to in this Agreement, in each case to the extent relating to an Agent’s obligations under Section 1(a) (but not, for the avoidance of doubt, its obligations under Section 3) or the implied covenant of good faith and fair dealing (to the extent applicable), except to the extent that it shall be determined by a court of competent jurisdiction in a judgment that has become final and that is no longer subject to appeal or other review that any losses, claims, damages, liabilities or expenses incurred by the Company resulted from the gross negligence or willful misconduct of such Agent in performing the services that are the subject of this Agreement.

9.          Termination. This Agreement may be terminated in the sole discretion of the Placement Agent by notice to the Company given prior to the Closing Date in the event that:

16

(a)   the Company shall have failed, refused or been unable in any material respect to perform the obligations and satisfy the conditions on its part to be performed or satisfied hereunder at or prior thereto or, if at or prior to the Closing Date;

(b)   any of the Company or any of its subsidiaries shall have sustained any loss or interference with respect to its businesses attributable to any event or development or series thereof that, in the sole judgment of the Placement Agent, individually or in the aggregate, has a material adverse effect on the Company and its subsidiaries, taken as a whole (including, without limitation, a change in control of the Company or any of its subsidiaries), except in each case as described in the Company’s Exchange Act Filings on the date hereof (exclusive of any amendment or supplement thereto);

(c)   (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE MKT LLC, the NASDAQ Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade or (ii) trading of any securities of the Company shall have been suspended on any exchange;

(d)   (i) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred or (ii) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities;

(e)   there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the Placement Agent’s judgment, is material and adverse and which, singly or together with any other event specified in this Section 9, makes it, in the Placement Agent’s judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Securities on the terms and in the manner contemplated in the Preliminary Memorandum, the Final Term Sheet or the Final Memorandum; or

(f)    any securities of the Company shall have been downgraded by any nationally recognized statistical rating organization or any such organization shall have publicly announced that it has under surveillance or review, or has changed its outlook with respect to, its ratings of any securities of the Company (other than an announcement with positive implications of a possible upgrading).

Termination of this Agreement pursuant to this Section 9 shall be without liability of any party to any other party except as provided in Sections 7 and 8 hereof.

10.        Survival of Agreements, Representations, Warranties and Indemnities. The respective agreements, representations, warranties, indemnities and other statements of the Company or its officers and of the Agents set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Agent or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities.  The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.
