Ladies and Gentlemen:

New Source Energy Corporation, a Delaware corporation (the “Company”), proposes, subject to the terms and conditions stated herein, to issue and sell an aggregate of shares (the “Firm Shares”) of the Company’s common stock, $0.001 par value per share (the “Common Stock”), to the several underwriters named in Schedule I (collectively, the “Underwriters”), for whom BMO Capital Markets Corp. (“BMOCM”) and KeyBanc Capital Markets Inc. (“KBCM”) are acting as representatives (the “Representatives”). The Company has also agreed to grant to the Underwriters an option (the “Option”) to purchase up to an additional shares of Common Stock (the “Option Shares”) on the terms and for the purposes set forth in Section 1(b). The Firm Shares and the Option Shares are hereinafter collectively referred to as the “Shares.”

As a part of the offering contemplated by this Agreement, SunTrust ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇, Inc. (in such capacity, the “Designated Underwriter”) has agreed to reserve out of the Firm Shares to be purchased by the Designated Underwriter up to shares in the aggregate for sale (either directly or through Fidelity Capital Markets, a division of National Financial Services LLC) to the Company’s employees, officers and directors and other parties associated with the Company (collectively, “Participants”), as set forth in the Prospectus (as defined herein) under the heading “Underwriting” (the “Directed Share Program”). The Firm Shares to be sold by the Designated Underwriter pursuant to the Directed Share Program (the “Directed Shares”) will be sold pursuant to this Agreement at the initial public offering price. Any Directed Shares not subscribed for by the end of the business day on which this Agreement is executed will be offered to the public by the Designated Underwriter as set forth in the Prospectus.

(b) Purchase of Option Shares. Subject to all the terms and conditions of this Agreement, the Company grants the Option to the several Underwriters to purchase, severally and not jointly, all or part of the Option Shares from the Company at the same price per share as the Underwriters shall pay for the Firm Shares. The Option may be exercised only to cover over-allotments in the sale of the Firm Shares by the Underwriters and may be exercised in whole or in part at any time upon written notice (the “Option Shares Notice”) by the Representatives to the Company no later than 12:00 noon, New York City time, on or before the 30th day after the date of this Agreement, at least two and no more than five business days before the date specified for closing in the Option Shares Notice (the “Option Closing Date”) setting forth the aggregate number of Option Shares to be purchased and the time and date for such purchase.

Each of the Registration Statement, any Rule 462(b) Registration Statement and any post-effective amendment thereto, at the time it became effective and at all subsequent times, complied and will comply in all material respects with the Act and the Rules and Regulations, and did not and will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading. The Prospectus, as amended or supplemented, as of its date and at all subsequent times, complied and will comply in all material respects with the Act and the Rules and Regulations, and did not and will not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Each preliminary prospectus and the Prospectus delivered to the Underwriters for use in connection with this offering is identical to the electronically transmitted copies thereof filed with the Commission on ▇▇▇▇▇, except to the extent permitted by Regulation S-T. The foregoing representations and warranties in this Section 3(c) do not apply to any statements or omissions made in reliance on and in conformity with information relating to any Underwriter furnished in writing to the Company by the Representatives specifically for inclusion in the Registration Statement or Prospectus or any amendment or supplement thereto, it being understood and agreed that the only such information is that described as such in Section 6(b) hereof.

6. Indemnification.

(a) Indemnification of the Underwriters. The Company shall indemnify and hold harmless each Underwriter, the directors, officers, employees, counsel and agents of each Underwriter and each person, if any, who controls each Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any and all losses, claims, liabilities, expenses and damages (including any and all investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding between any of the indemnified parties and any indemnifying parties or between any indemnified party and any third party, or otherwise, or any claim asserted), to which they, or any of them, may become subject under the Act, the Exchange Act or other federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, liabilities, expenses or damages arise out of or are based on (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including any information deemed to be a part thereof pursuant to Rules 430A, 430B or 430C, as applicable, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, any Issuer Free Writing Prospectus or the Prospectus (or any amendment or supplement thereto) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (iii) any untrue statement or alleged untrue statement of a material fact contained in any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Shares, including any road show or investor presentations made to investors by the Company (whether in person or electronically) or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Company shall not be liable to the extent that

such loss, claim, liability, expense or damage arises from the sale of the Shares in the public offering to any person by an Underwriter and is based on an untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to any Underwriter furnished in writing to the Company by the Representatives on behalf of any Underwriter expressly for inclusion in the Registration Statement, any preliminary prospectus, any Issuer Free Writing Prospectus or the Prospectus. This indemnity agreement will be in addition to any liability that the Company might otherwise have.

(b) Indemnification of the Company. Each Underwriter shall, severally and not jointly, indemnify and hold harmless the Company, each person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, each director of the Company and each officer of the Company who signs the Registration Statement to the same extent as the indemnity set forth in Section 6(a), but only insofar as losses, claims, liabilities, expenses or damages arise out of or are based on any untrue statement or omission or alleged untrue statement or omission made in reliance on and in conformity with information relating to such Underwriter furnished in writing to the Company by the Representatives on behalf of such Underwriter expressly for use in the Registration Statement, any preliminary prospectus or the Prospectus, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter: . This indemnity will be in addition to any liability that each Underwriter might otherwise have.

(c) Indemnification of the Independent Underwriter. Without limitation and in addition to its obligation under the other subsections of this Section 6, the Company agrees to indemnify and hold harmless the Independent Underwriter (as defined in Section 9), its officers and employees and each person, if any, who controls the Independent Underwriter within the meaning of Section 15 of the Act or Section 20 of the Exchange Act from and against any loss, claim, damage, liability or expense, as incurred, arising out of or based upon the Independent Underwriter’s acting as a “qualified independent underwriter” (within the meaning of FINRA Conduct Rule 5121) in connection with the offering contemplated by this Agreement, and agrees to reimburse each such indemnified person for any legal or other expense reasonably incurred by them in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or expense results from the gross negligence or willful misconduct of the Independent Underwriter. Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to this Section 6(c) in respect of such action, then in addition to such separate firm for any indemnified parties other than the Independent Underwriter and the controlling persons specified below, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for the Independent Underwriter and all persons, if any, who control the Independent Underwriter within the meaning of either Section 15 of the Act or Section 20 of the Exchange Act, if, in the reasonable judgment of the Independent Underwriter, there may exist a conflict of interest between the Independent Underwriter and such other indemnified parties. Any such separate counsel shall be designated in writing by the Independent Underwriter.

(d) Indemnification Procedures. Any party that proposes to assert the right to be indemnified under this Section 6 shall, promptly after receipt of notice of commencement of any action against such party in respect of which a claim is to be made against an indemnifying party or parties under this Section 6, notify each such indemnifying party of the commencement of such action, enclosing a copy of all papers served, but the omission so to notify such indemnifying party shall not relieve the indemnifying party from any liability that it may have to any indemnified party under the foregoing provisions of this Section 6 unless, and only to the extent that, such omission results in the forfeiture of substantive rights or defenses by the indemnifying party. If any such action is brought against any indemnified party and it notifies the indemnifying party of its commencement, the indemnifying party will be entitled to participate in and, to the extent that it elects by delivering written notice to the indemnified party promptly after receiving notice of the commencement of the action from the indemnified party, jointly with any other indemnifying party similarly notified, to assume the defense of the action, with counsel satisfactory to the indemnified party, and after notice from the indemnifying party to the indemnified party of its election to assume the defense, the indemnifying party will not be liable to the indemnified party for any legal or other expenses except as provided below and except for the reasonable costs of investigation subsequently incurred by the indemnified party in connection with the defense. The indemnified party will have the right to employ its own counsel in any such action, but the fees, expenses and other charges of such counsel will be at the expense of such indemnified party unless (i) the employment of counsel by the indemnified party has been authorized in writing by the indemnifying party, (ii) the indemnified party has reasonably concluded (based on advice of counsel) that there may be legal defenses available to it or other indemnified parties that are different from or in addition to those available to the indemnifying party, (iii) a conflict or potential conflict exists (based on advice of counsel to the indemnified party) between the indemnified party and the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party) or (iv) the indemnifying party has not in fact employed counsel to assume the defense of such action within a reasonable time after receiving notice of the commencement of the action, in each of which cases the reasonable fees, disbursements and other charges of counsel shall be at the expense of the indemnifying party or parties. It is understood that the indemnifying party or parties shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees, disbursements and other charges of more than one separate firm admitted to practice in such jurisdiction at any one time for all such indemnified party or parties. All such fees, disbursements and other charges shall be reimbursed by the indemnifying party promptly as they are incurred. An indemnifying party shall not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld or delayed), but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party 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 an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the third and fourth sentences of this paragraph, the indemnifying party 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 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party

shall, without the prior written consent of each indemnified party, settle or compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding relating to the matters contemplated by this Section 6 (whether or not any indemnified party is a party thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising or that may arise out of such claim, action or proceeding and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(e) Contribution. In order to provide for just and equitable contribution in circumstances in which the indemnification provided for in the foregoing paragraphs of this Section 6 is applicable in accordance with its terms but for any reason is held to be unavailable from the Company or the Underwriters, the Company and the Underwriters shall contribute to the total losses, claims, liabilities, expenses and damages (including any investigative, legal and other expenses reasonably incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claim asserted, but after deducting any contribution received by the Company from persons other than the Underwriters, such as persons who control the Company within the meaning of the Act, officers of the Company who signed the Registration Statement and directors of the Company, who also may be liable for contribution) to which the Company and the Underwriters may be subject in such proportion as shall be appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Company bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. If, but only if, the allocation provided by the foregoing sentence is not permitted by applicable law, the allocation of contribution shall be made in such proportion as is appropriate to reflect not only the relative benefits referred to in the foregoing sentence but also the relative fault of the Company, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions which resulted in such loss, claim, liability, expense or damage, or action in respect thereof, as well as any other relevant equitable considerations with respect to such offering. Such relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or Representatives on behalf of the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 6(e) were to be determined by pro rata allocation or by any other method of allocation (even if the Underwriters were treated as one entity for such purpose) which does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, liability, expense or damage, or action in respect thereof, referred to above in this Section 6(e) shall be deemed to include, for purpose of this Section 6(e), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 6(e), no Underwriter shall be required to contribute any amount in excess of the underwriting discounts and commissions received by it, and no person found 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 Underwriters’ obligations to contribute as provided in this Section 6(e) are several in proportion to their respective underwriting obligations and not joint.

(f) Survival. The indemnity and contribution agreements contained in this Section 6 and the representations, warranties and agreements of the Company contained in this Agreement or in certificates or other instruments delivered pursuant hereto shall remain operative and in full force and effect regardless of (i) any investigation made by or on behalf of the Underwriters, including the Independent Underwriter in its capacity as such, (ii) acceptance of any of the Shares and payment therefor or (iii) any termination of this Agreement.

(g) Indemnification Pursuant to the Directed Share Program. The Company agrees to indemnify and hold harmless the Designated Underwriter and its affiliates and each person, if any, who controls the Designated Underwriter or its affiliates within the meaning of Section 15 of the Act or Section 20 of the Exchange Act (“Indemnified Entities”), from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) (i) arising out of or based on any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the consent of the Company for distribution to Participants in connection with the Directed Share Program, or arising out of or based on any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; (ii) arising out of or based on the failure of any Participant to pay for and accept delivery of Directed Shares that the Participant has agreed to purchase; or (iii) related to, arising out of, or in connection with the Directed Share Program other than losses, claims, damages or liabilities (or expenses relating thereto) that are finally judicially determined to have resulted from the bad faith or gross negligence of one or more Indemnified Entities. Section 6(d) shall apply equally to any proceeding brought against the Indemnified Entities in respect of which indemnity may be sought against the Company pursuant to the immediately preceding sentence, except that the Company shall be liable for the expenses of one separate counsel (in addition to any local counsel) for the Indemnified Entities separate and in addition to counsel for the persons who may seek indemnification pursuant to Section 6(a), in any such proceeding, action or suit.

7. Termination. The obligations of the several Underwriters under this Agreement may be terminated at any time on or prior to the Closing Date (or, with respect to the Option Shares, on or prior to the Option Closing Date), by notice to the Company from the Representatives, without liability on the part of any Underwriter to the Company, if, prior to delivery and payment for the Firm Shares (or the Option Shares, as the case may be), in the sole judgment of the Representatives, any of the following shall occur:

(a) trading or quotation in any of the equity securities of the Company shall have been suspended or limited by the Commission or by an exchange or otherwise;

(b) trading in securities generally on the New York Stock Exchange or the Nasdaq Global Market shall have been suspended or limited or minimum or maximum prices shall have been generally established on such exchange, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by such exchange or by order of the Commission or any court or other governmental authority;

(d) a material disruption in securities settlement, payment or clearance services in the United States or other relevant jurisdiction shall have occurred;

(e) the United States shall have become engaged in new hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States or there shall have occurred such a material adverse change in general economic, political or financial conditions, including, without limitation, as a result of terrorist activities after the date hereof (or the effect of international conditions on the financial markets in the United States shall be such), or any other calamity or crisis shall have occurred, the effect of any of which is such as to make it impracticable or inadvisable to market the Shares on the terms and in the manner contemplated by the General Disclosure Package and Prospectus;

(f) if the Company shall have sustained a loss material or substantial to the Company by reason of flood, fire, accident, hurricane, earthquake, theft, sabotage, or other calamity or malicious act, whether or not such loss shall have been insured, the effect of any of which is such as to make it impracticable or inadvisable to market the Shares on the terms and in the manner contemplated by the General Disclosure Package and Prospectus; or

(g) if there shall have been a Material Adverse Change.

8. Substitution of Underwriters. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase any of the Firm Shares which it or they have agreed to purchase hereunder, and the aggregate number of Firm Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, the other Underwriters shall be obligated, severally, to purchase the Firm Shares on such date which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase, in the proportions which the number of Firm Shares which they have respectively agreed to purchase pursuant to Section 1 bears to the aggregate number of Firm Shares which all such non-defaulting Underwriters have so agreed to purchase, or in such other proportions as the Representatives may specify; provided that in no event shall the maximum number of Firm Shares which any Underwriter has become obligated to purchase pursuant to Section 1 be increased pursuant to this Section 8 by more than one-ninth of the number of Firm Shares agreed to be purchased by such Underwriter without the prior written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase any Firm Shares and the aggregate number of Firm Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase exceeds one-tenth of the aggregate number of the Firm Shares and arrangements satisfactory to the Company and the Representatives for the purchase of such Firm Shares are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company (except as provided in

Section 4(l)) for the purchase or sale of any Shares under this Agreement. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, the General Disclosure Package and in the Prospectus or in any other documents or arrangements may be effected. Any action taken pursuant to this Section 8 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

9. Qualified Independent Underwriter.

(a) The Company hereby confirms its engagement of the services of ▇▇▇▇▇▇▇ ▇▇▇▇ & Company L.L.C. (in such capacity, the “Independent Underwriter”) without compensation as, and the Independent Underwriter hereby confirms its agreement with the Company to render services as, a “qualified independent underwriter” within the meaning of FINRA Rule 5121 with respect to the offering and sale of the Shares.

(b) The Independent Underwriter has participated in the preparation of the Registration Statement, the General Disclosure Package and the Prospectus and has complied in all material respects with all of the requirements of FINRA Rule 5121 applicable to it in connection with the offering and sale of the Shares.

Ladies and Gentlemen:

In consideration of the agreement of the several Underwriters, for which BMO Capital Markets Corp. (“BMOCM”) and KeyBanc Capital Markets Inc.

Notwithstanding the foregoing, and subject to the conditions below, the undersigned may transfer Stock or such other convertible, exercisable or exchangeable securities without the prior written consent of BMOCM and KBCM, provided that (1) BMOCM and KBCM receive a signed lock-up agreement in the form of this letter agreement for the balance of the Lock-Up Period from each donee, trustee, distributee, or transferee, as the case may be, (2) any such transfer shall not involve a disposition for value, (3) such transfers are not publicly reportable
