For purposes of this Agreement, “free writing prospectus” has the meaning set forth in Rule 405 under the Securities Act; “Time of Sale Prospectus” means the Preliminary Prospectus, together with the free writing prospectuses, if any, each identified in Schedule II hereto (each, a “Permitted Free Writing Prospectus”), and other information conveyed to purchasers of the Units at or prior to the Time of Sale as set forth in Schedule II hereto; “Time of Sale” means : p.m. (Central Time) on the date of this Agreement; “road show” has the meaning set forth in Rule 433(h)(4) under the Securities Act, and “bona fide electronic road show” has the meaning set forth in Rule 433(h)(5) under the Securities Act.

potential environmental liabilities to third parties known to be arising from the Partnership’s operations or, to the Partnership Parties’ knowledge, that of its contract operator on the Partnership Properties).

Other than with respect to items that would not reasonably be expected to have a Material Adverse Effect, each pension plan established and which is currently maintained by any Partnership Party or New Source Energy that is intended to be qualified under Section 401 of the Code is so qualified and, to the knowledge of the Partnership Parties, no event or fact exists which would adversely affect such qualification. To the knowledge of the Partnership Parties as of the date of this Agreement, none of the Partnership Parties or New Source Energy or any ERISA Affiliate currently maintains, contributes to or has any liability (contingent or otherwise) with respect to a “defined benefit plan” (within the meaning of Section 3(35) of ERISA) or a pension plan that is subject to Title IV of ERISA.

(oo) At the Closing Date and each Option Closing Date, if any, after giving effect to the Transactions, except as otherwise would not have a Material Adverse Effect, the buildings, structures and equipment to be owned by the Partnership Parties are in good operating condition and repair and have been reasonably maintained consistent with standards generally followed in the industry (giving due account to the age and length of use, ordinary wear and tear excepted), are adequate and suitable for their present uses and, in the case of buildings and other structures, are structurally sound.

(pp) At the Closing Date and each Option Closing Date, if any, after giving effect to the Transactions, the Partnership Parties will possess all certificates, authorizations and permits issued by the appropriate federal, state or foreign regulatory authorities necessary to conduct their respective businesses, except where the failure to so comply would not have a Material Adverse Effect, and neither of the Partnership Parties has received any notice of proceedings relating to the revocation or modification of any such certificate, authorization or permit which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would have a Material Adverse Effect.

(qq) The Partnership maintains “internal control over financial reporting” (as defined in Rules 13a-15 and 15d-15 under the Exchange Act). The Partnership’s internal control over financial reporting has been designed by the General Partner’s principal executive officer and principal financial officer, or under their supervision, to provide reasonable assurance regarding the reliability of financial reporting and

the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and is effective in performing the functions for which it was established. Except as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus, since the end of the Partnership’s most recent audited fiscal year, there has been (i) no significant deficiency or material weakness in the design or operation of the Partnership’s internal control over financial reporting (whether or not remediated) which is reasonably likely to adversely affect the Partnership’s ability to record, process, summarize and report financial information, and (ii) no change in the Partnership’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Partnership’s internal control over financial reporting.

(vv) Neither of the Partnership Parties nor, to the knowledge of the Partnership Parties, any director, officer, agent, employee or affiliate of the Partnership Parties is aware of or has taken any action, directly or indirectly, that would result in a violation by such persons of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder; and the Partnership Parties have instituted and maintain policies and procedures designed to ensure continued compliance therewith, including without limitation a system of internal

accounting controls sufficient to provide reasonable assurances that (i) transactions are executed in accordance with management’s general or specific authorization, (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets, (iii) access to assets is permitted only in accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(ww) The operations of the Partnership Parties are, and have been conducted at all times, in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all applicable jurisdictions, the rules and regulations thereunder and any related or similar applicable rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”), except to the extent that any such noncompliance would not, individually or in the aggregate, result in a Material Adverse Effect, and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Partnership Parties with respect to the Money Laundering Laws is pending or, to the best knowledge of the Partnership Parties, threatened. Neither of the Partnership Parties nor, to the knowledge of the Partnership Parties, any director, officer, agent, employee, affiliate or person acting on behalf of the Partnership Parties is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Partnership will not directly or indirectly use the proceeds of this offering, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

(aaa) The Partnership (i) has not alone engaged in communications with potential investors in reliance on Section 5(d) of the Securities Act other than Permitted Section 5(d) Written Communications with the consent of the Representatives with entities that are QIBs or IAIs and (b) has not authorized anyone other than the Representatives to engage in such communications; the Partnership reconfirms that the Representatives have been authorized to act on its behalf in undertaking Section 5(d) Communications; as of the Applicable Time, each Section 5(d) Written Communication, when considered together with the Time of Sale Prospectus, did not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; each Section 5(d) Written Communication, if any, does not, as of the date hereof, conflict with the information contained in the Registration Statement, the Preliminary Prospectus and the Prospectus; and the Partnership has filed publicly on the Commission’s XXXXX database at least 21 calendar days prior to any “road show” (as defined in Rule 433 under the Act), any confidentially submitted registration statement and registration statement amendments relating to the offer and sale of the Units.

2. Agreements to Sell and Purchase. On the basis of the representations and warranties herein contained, but subject to the conditions herein set forth, the Partnership hereby agrees to sell, and each Underwriter agrees, severally and not jointly, to purchase from the Partnership, at a purchase price of $ per unit (the “Purchase Price”), the amount of Firm Units set forth opposite such Underwriter’s name in Schedule I hereto.

On the basis of the representations and warranties herein contained, but subject to the conditions herein set forth, the Partnership hereby grants to the Underwriters, severally and not jointly, an option to purchase, ratably in accordance with the number of Firm Units to be purchased by each Underwriter, up to Option Units, at a price equal to the Purchase Price (the “Over-Allotment Option”) [less an amount per unit equal to any cash distribution declared by the Partnership and payable by the Partnership on the Firm Units but not payable on the Option Units. The Over-Allotment Option will expire at the close of business on the 30th day after the date hereof (such thirty-day period, the “Option Period”) and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments that may be made in connection with the offering and distribution of the Firm Units upon notice by the Representatives to the Partnership setting forth the number of Option Units to be purchased by the Underwriters and the time and date of payment and delivery for such Option Units. Each time and date of payment and delivery for such Option Units (an “Option Closing Date”) must be at least two business days after the written notice is given and may not be earlier than the closing date for the Firm Units or later than ten business days after the date of such notice. If the Over-Allotment Option is exercised as to all or any portion of the Option Units, the Partnership will sell to the Underwriters that number of Option Units as to which the Underwriters are exercising the Over-Allotment Option, each Underwriter agrees, severally and not jointly, to purchase the number of Option Units (subject to such adjustments to eliminate fractional units as the Representatives may determine) that bears the same proportion to the total number of Option Units to be purchased on such Option Closing Date as the number of Firm Units set forth in Schedule I hereto opposite the name of such Underwriter bears to the total number of Firm Units.

3. Payment and Delivery. Payment for and delivery of the Firm Units shall be made at the office of Xxxxxx & Xxxxxx L.L.P., 0000 Xxxxxx Xxxxxx, Xxxxx 0000, Xxxxxxx, Xxxxx 00000, or at such other place as shall be agreed upon by the Representatives and the Partnership, at 10:00 a.m., Central Time, on , 201 , or at such other time on the same or such other date, not later than , 201_, as shall be agreed upon in writing by the Representatives and the Partnership.

Payment for the Firm Units and the Option Units, if any, shall be made to the Partnership by wire transfer of immediately available funds to a single bank account designated by the Partnership against delivery to the Representatives for the respective accounts of the Underwriters of the Units to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Firm Units and the Option Units, if any, that it has agreed to purchase. Xxxxx, individually and not as a Representative of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Firm Units and the Option Units, if any, to be purchased by any Underwriter whose funds have not been received by the Closing Date or the relevant Option Closing Date, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

The Firm Units and Option Units shall be registered in such names and in such denominations as the Representatives shall request in writing not later than one full business day prior to the Closing Date or the applicable Option Closing Date, as the case may be. The Firm Units and Option Units shall be delivered to the Representatives on the Closing Date or an Option Closing Date, as the case may be, for the respective accounts of the several Underwriters, with any transfer taxes payable in connection with the transfer of the Units to the Underwriters duly paid, against payment of the Purchase Price therefor.

(e) To advise the Representatives promptly of any request by the Commission for amendments or supplements to the Registration Statement, any Preliminary Prospectus or Prospectus or for additional information with respect thereto, or of notice of institution of proceedings for, or the entry of a stop order, suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus, the Time of Sale Prospectus or the Prospectus; and if the Commission should enter such a stop order, to use its best efforts to obtain the lifting or removal of such order as soon as possible.

(f) If the Time of Sale Prospectus is being used to solicit offers to buy the Units at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(g) If, during such period after the first date of the public offering of the Units as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) under the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the

(k) Except as set forth in this Agreement, during the period beginning on and including the date of this Agreement and continuing to and including 180 days after the date of this Agreement, and without the prior written consent of Xxxxx, the Partnership will not (i) issue, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or

indirectly, any Common Units or any securities convertible into or exercisable or exchangeable for Common Units, except that the Partnership may issue Common Units or any securities convertible or exchangeable into Common Units as payment of any part of the purchase price for businesses that are acquired by the Partnership; provided that any recipient of such Common Units must agree in writing to be bound by the terms of this Section 5(k) for the remaining term of the 180-day restricted period, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Units, whether such transaction described in clause (i) or (ii) above is to be settled by delivery of the Common Units or such other securities, in cash or otherwise, (iii) file any registration statement with the Commission relating to the offering of any Common Units or any securities convertible into or exercisable or exchangeable for Common Units, or (iv) publicly announce an intention to effect any transaction specified in clause (i), (ii) or (iii) above. The restrictions contained in the preceding sentence shall not apply to (A) the Units to be sold hereunder, (B) the issuance of Common Units, and options to purchase Common Units pursuant to the Partnership’s option plans under the terms of such plans in effect on the date hereof, provided such options are granted at fair market value and in amounts and with exercise terms consistent with the Partnership’s past practice, or the sale of Common Units to employees pursuant to the Partnership’s employee purchase plans (or the filing of a registration statement on Form S-8 to register Common Units issuable under such plans), or (C) the issuance by the Partnership of Common Units upon the exercise of an option or warrant or the conversion of a security outstanding on the date of the Underwriting Agreement of which Xxxxx has been advised in writing. Notwithstanding the foregoing, if (1) during the last 17 days of the 180-day restricted period the Partnership issues an earnings release or material news or a material event relating to the Partnership occurs; or (2) prior to the expiration of the 180-day restricted period, the Partnership announces that it will release earnings results during the 16-day period beginning on the last day of the 180-day period, the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event. The Partnership shall promptly notify Xxxxx of any earnings release, news or event that may give rise to an extension of the initial 180-day restricted period.

(l) To comply with Rule 433(d) under the Securities Act (without reliance on Rule 164(b) under the Act) and with Rule 433(g) under the Securities Act.

(m) Not to take, directly or indirectly, any action designed, or which will constitute, or has constituted, or might reasonably be expected to cause or result in the stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Units.

(n) Not, at any time at or after the execution of this Agreement, to offer or sell any Units by means of any “prospectus” (within the meaning of the Securities Act) or use any “prospectus” (within the meaning of the Securities Act) in connection with the offer or sale of the Units, except in each case other than the Prospectus.

(o) To maintain a transfer agent and, if necessary under the jurisdiction of incorporation of the Partnership, a registrar for the Common Units.

(p) To apply the net proceeds to the Partnership from the sale of the Units in the manner set forth under the caption “Use of Proceeds” in the Prospectus.

(q) The Partnership will promptly notify the Representatives if the Partnership ceases to be an Emerging Growth Company at any time prior to the later of (a) the time when a prospectus relating to the Units is not required by the Securities Act to be delivered (whether physically or through compliance with Rule 172 under the Securities Act or any similar rule) and (b) the expiration of the lock-up period described in Section 6(m) above.

(r) If at any time following the distribution of any Permitted Section 5(d) Communication, there occurred or occurs an event or development as a result of which such Permitted Section 5(d) Communication included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Partnership will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Permitted Section 5(d) Communication to eliminate or correct such untrue statement or omission.

6. Expenses. The Partnership agrees to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Partnership’s counsel and the Partnership’s accountants in connection with the registration and delivery of the Units under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any Preliminary Prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by, or referred to by the Partnership and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, as may be reasonably requested by the Underwriters for use in connection with the offering and sale of the Units, (ii) all costs and expenses related to the preparation, printing, issuance and delivery of the certificates for the Units to the Underwriters, including any transfer or other taxes payable thereon, (iii) the costs of printing or producing any securities or blue sky memorandum in connection with the offer and sale of the Units under the securities laws of the jurisdictions in which the Units may be offered or sold and all expenses in connection with the qualification of the Units for offer and sale under such securities laws as provided in Section 6(j) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the blue sky memorandum, (iv) all filing fees incurred in connection with the review of the terms of the sale of the Units by FINRA. (v) all fees and expenses in connection with the preparation and filing of the registration statement on Form 8-A relating to the Common Units and all costs and expenses incident to listing the Units on the

NYSE, (vi) the costs and charges of any transfer agent, registrar or depositary, (vii) the costs and expenses of the Partnership relating to investor presentations on any road show undertaken in connection with the marketing of the offering of the Units, including, without limitation, expenses associated with the preparation or dissemination of any road show, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the Partnership, travel and lodging expenses of the representatives and officers of the Partnership Parties and any such consultants, and one-half the costs and expenses of any aircraft chartered in connection with the road show, (viii) the document production charges and expenses associated with printing this Agreement, (ix) all expenses in connection with any offer and sale of the Units outside of the United States, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with offers and sales outside of the United States, and (x) all other costs and expenses incident to the performance of the obligations of the Partnership hereunder for which provision is not otherwise made in this Section; provided, that except as provided in this Section 6, the Underwriters shall pay their own costs and expenses, including the costs and expenses of their counsel.

The Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, transfer taxes payable on resale of any of the Units by them and any advertising expenses connected with any offers they may make. Notwithstanding the above, if the sale of the Units provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 5 is not satisfied, because of any termination of this Agreement by the Underwriters pursuant to Section 9(b) hereof or because of any refusal, inability or failure on the part of the Partnership to perform any obligation or covenant hereunder or comply with any provision hereof other than by reason of a default by any of the Underwriters, the Partnership will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, through the Representatives on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereby.

7. Indemnity and Contribution. (a) The Partnership Parties, jointly and severally, agree to indemnify and hold harmless each Underwriter, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and affiliates of any Underwriter who have or are alleged to have participated in the distribution of Units as underwriters, within the meaning of Rule 405 under the Securities Act 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) caused by, arising out of or based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, or 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, or (ii) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, or the Prospectus or any amendment or supplement thereto, or any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which there were made, not misleading; provided, however, that the Partnership Parties shall not be liable under this Section 7(a) to the extent that such losses, claims, damages or liabilities are caused by, arise out of or are based upon any such untrue statement or omission or alleged untrue statement or omission made therein in reliance upon and in conformity with information relating to any Underwriter furnished to the Partnership Parties in writing by such Underwriter through the Representatives expressly for use therein, it being agreed that the only information furnished by or on behalf of the Underwriters to the Partnership Parties expressly for use therein consists of the information described as such in Section 7(b) hereof.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Partnership Parties, the directors of the General Partner, the officers of the General Partner who sign the Registration Statement and each person, if any, who controls the Partnership Parties within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act 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) described in the indemnity contained in Section 7(a) above, as incurred, but only with respect to such untrue statements or omissions or alleged untrue statements or omissions made in the Registration Statement or any amendment thereof, any Preliminary Prospectus, the Time of Sale Prospectus, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, or the Prospectus, in reliance upon and in conformity with information relating to such Underwriter furnished to the Partnership Parties in writing by such Underwriter through the Representatives expressly for use therein, it being agreed that the only information furnished by the Underwriters to the Partnership Parties expressly for use therein is the information set forth (i) in the last paragraph of the cover page regarding delivery of the Units and, under the heading “Underwriting,” (ii) the list of Underwriters and their respective participation in the sale of the Units, (iii) the sentences related to concessions and reallowances and (iv) the paragraphs related to stabilization, syndicate covering transactions and penalty bids and the information regarding the limitations on sales to discretionary accounts in the Registration Statement, the Time of Sale Prospectus and the Prospectus.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to this Section 7 such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it

from any liability that it may have otherwise than on account of this indemnity agreement. The indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party 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 indemnifying party 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 indemnifying party 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 indemnifying party 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 (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, and (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Partnership Parties, the directors of the General Partner, the officers of the General Partner who sign the Registration Statement and each person, if any, who controls the Partnership Parties within the meaning of either such Section, and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by Xxxxx. In the case of any such separate firm for the Partnership Parties, and such directors, officers and control persons of the Partnership Parties, such firm shall be designated in writing by the Partnership Parties. The indemnifying party 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 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 second and third 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 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.

(d) To the extent the indemnification provided for in 7(a) or 7(b) is unavailable to or insufficient to hold harmless any indemnified party above in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party 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 Partnership Parties on the one hand and the Underwriters on the other hand from the offering of the Units 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 Partnership Parties on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Partnership on the one hand and the Underwriters on the other hand in connection with the offering of the Units shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Units (before deducting expenses) received by the Partnership bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus. The relative fault of the Partnership on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the respective number of Units they have purchased hereunder, and not joint.

(e) The Partnership Parties and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 7(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 7(d) shall be deemed to include, subject to the limitations set forth above, 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 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f) The indemnity and contribution provisions contained in this Section 7 and the representations, warranties and other statements of the Partnership contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, or the Partnership, its officers or directors or any person controlling the Partnership and (iii) acceptance of and payment for any of the Units.

8. Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Partnership, if after the execution and delivery of this Agreement and prior to the Closing Date (a) trading generally shall have been suspended or materially limited or minimum prices shall have been established on, or by, as the case may be, any of the New York Stock Exchange, or the NASDAQ Global Market, (b) trading of the Partnership’s Common Units shall have been suspended or materially limited on the NYSE, (c) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (d) any moratorium or material limitation 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 declaration by the United States of a national emergency or war, or any other calamity or crisis, the effect of which on financial markets makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Units as contemplated in the Time of Sale Prospectus or the Prospectus (exclusive of any supplement thereto).

9. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase and pay for any of the Units that it has or they have agreed to purchase hereunder, and the aggregate number of Units which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Units to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Units set forth opposite their respective names in Schedule I hereto bears to the aggregate number of Firm Units set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase and pay for the Units which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Units that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such number of Units without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Units and the aggregate number of Firm Units with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Units to be purchased on such date, and arrangements satisfactory to the Representatives and the Partnership for the purchase of such Firm Units are not made within 36 hours

after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Partnership. In any such case either the Representatives or the Partnership 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, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Option Units and the aggregate number of Option Units with respect to which such default occurs is more than one-tenth of the aggregate number of Option Units to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Option Units to be sold on such Option Closing Date or (ii) purchase not less than the number of Option Units that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

10. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Partnership and the Underwriters set forth or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or the Partnership or any of the officers, directors, employees, agents or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Units. The provisions of Sections 6 and 7 hereof shall survive the termination or cancellation of this Agreement.

11. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Units, represents the entire agreement between the Partnership, on the one hand, and the Underwriters, on the other, with respect to the preparation of any Preliminary Prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Units.

(b) The Partnership acknowledges that in connection with the offering of the Units: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Partnership or any other person; (ii) the Underwriters owe the Partnership only those duties and obligations set forth in this Agreement and prior written agreements (to the extent not superseded by this Agreement), if any; and (iii) the Underwriters may have interests that differ from those of the Partnership. The Partnership waives to the full extent permitted by applicable law any claims it may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Units.

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

13. Applicable Law. This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York.

14. Headings. The headings of the sections of this Agreement have been inserted for convenience of reference only and shall not be deemed a part of this Agreement.

15. Notices. All communications hereunder shall be in writing and effective only upon receipt and if to the Underwriters shall be delivered, mailed or sent to the Representatives in care of Xxxxxx X.

EXHIBIT A

FORM OF OPINION OF COMPANY’S COUNSEL

TO BE DELIVERED PURSUANT TO SECTION 5(d)

1. The Partnership is a limited partnership duly formed under the Delaware LP Act, is validly existing as a limited partnership in good standing under the laws of Delaware, has the limited partnership power and authority to own its property and to conduct its business as described in the Time of Sale Prospectus and is duly qualified to transact business and is in good standing in each jurisdiction listed on Annex A hereto;

2. The General Partner is a limited liability company duly formed under the Delaware LLC Act, is validly existing as a limited liability company in good standing under the laws of Delaware, has the limited liability company power and authority to own its property and to conduct its business as described in the Time of Sale Prospectus and is duly qualified to transact business and is in good standing in each jurisdiction listed on Annex A hereto;

3. After giving effect to the Transactions, the issued and outstanding partnership interests of the Partnership consist of [•] Common Units, [•] Subordinated Units, [•] General Partner Units and the Incentive Distribution Rights. Other than the Sponsor Units and the Incentive Distribution Rights, the Units are the only limited partner interests of the Partnership issued and outstanding on the date hereof;

4. The Units to be sold by the Partnership have been duly authorized for issuance and sale to the Underwriters pursuant to the Underwriting Agreement and, when issued and delivered by the Partnership in accordance with the terms of the Underwriting Agreement against payment of the consideration set forth therein, will be validly issued and fully paid (to the extent required by the Partnership Agreement) and non assessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act);

5. Except as described in the Registration Statement, the Time of Sale Prospectus and the Prospectus, the issuance and sale of the Units to be sold by the Partnership pursuant to the Underwriting Agreement are not subject to any preemptive rights, rights of first refusal or other similar rights of any securityholder of the Partnership or any other person arising under the organizational or governing documents of the Partnership;

6. This Agreement has been duly authorized, executed and delivered by the Partnership and the General Partner;

7. Neither the execution and delivery by the Partnership and General Partner of, nor the performance by the Partnership or General Partner of its obligations under, this Agreement will conflict with, contravene, result in a breach or violation of, or imposition of any lien, charge or encumbrance upon any property or assets of the Partnership or General Partner, or constitute a default under (i) the Delaware LP Act, the Delaware LLC Act, the laws of the State of Texas or federal law (the “Applicable Laws”); (ii) the certificate of formation, partnership agreement or operating agreement of the Partnership or General Partner; or (iii) any contract, agreement, obligation, covenant or instrument filed as exhibit to the Registration Statement , except for such conflict, contravention, breaches, violations, defaults, liens, charges or encumbrances, in the case of clauses (i) and (iii) that would not result in a Material Adverse Effect, it being understood that we do not express an opinion in clause (iii) of this paragraph (7) with respect to any securities or other anti-fraud laws;

8. No approval, authorization, consent, order or filing of or with any court or governmental body or agency under the Applicable Laws, is required in connection with the issuance and sale of the Units, the execution, delivery or performance by any of the Partnership Parties of the Underwriting Agreement, or for the consummation by the Partnership Parties of the Transactions contemplated by the Underwriting Agreement, other than (i) such as have been obtained under the Securities Act or the Exchange Act, (ii) such as may be required under the securities or blue sky laws of the various jurisdictions in which the Units are being offered by the Underwriters or the by-laws and rules of FINRA; (iii) such consents as have been obtained or made and (iv) such consents that, if not obtained, would not be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect;

9. The Registration Statement has been declared effective; to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings therefor have been initiated by the Commission. The Preliminary Prospectus has been filed in accordance with Rule 424(b) under the Act and the Prospectus has been filed in accordance with Rule 424(b) and 430A under the Act.

10. The Registration Statement at the time it was declared effective, including the information deemed to be a part thereof pursuant to Rule 430A under the Act, and the Prospectus, as of its date, each appeared on their fact to be appropriately responsive in all material respects to the applicable form requirements for registration statements on Form S-1 under the Act and the rules and regulations of the Commission thereunder; it being understood, however, that we express no view with respect to Regulation S-T or the financial statements, schedules, or other financial data, included in, or omitted from, the Registration Statement or the Prospectus. For purposes of this paragraph, we have assumed that the statements made in the Registration Statement and the Prospectus are correct and complete.

11. The Common Units, the Subordinated Units and the Incentive Distribution Rights conform in all material respects to the descriptions thereof contained in the Registration Statement, the Preliminary Prospectus and the Prospectus under the captions “Our Cash Distribution Policy and Restrictions on Distributions,” “Provisions of our Partnership Agreement Relating to Cash Distributions,” “Description of the Common Units,” and “The Partnership Agreement.”

12. The statements included in the Registration Statement, the Time of Sale Prospectus and the Prospectus under the captions “Provisions of our Partnership Agreement Relating to Cash Distributions,” “Conflicts of Interest and Fiduciary Duties,” “Business-Regulation of the Oil and Natural Gas Industry,” “Certain Relationships and Related Party Transactions,” “The Partnership Agreement,” and “Material Tax Consequences,” insofar as they purport to summarize any agreement, statute or regulation, are accurate summaries in all material respects;

13. The Partnership is not, and after giving effect to the offering and sale of the Units and the application of the proceeds thereof as described in the Prospectus will not be, required to register as an “investment company” as such term is defined in the Investment Partnership Act of 1940, as amended; and

14. Nothing has come to the attention of such counsel that causes such counsel to believe that:

(1) the Registration Statement or the prospectus included therein, at the time the Registration Statement became effective contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

Ladies and Gentlemen:

The undersigned understands that Xxxxxx X. Xxxxx & Co. Incorporated (“Baird”), Xxxxxx Xxxxxxxx & Company, Incorporated, BMO Capital Markets Corp., and Xxxxxxxxxxx & Co. Inc. (together with Baird, the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with New Source Energy Partners L.P., a Delaware limited partnership (the “Partnership”), relating to a proposed underwritten public offering (the “Public Offering”) of common units representing limited partner interests in the Partnership (the “Common Units”).

To induce you and the other Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of Baird on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 180 days after the date of the Underwriting Agreement (the “Restricted Period”), (1) issue, offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Units or any securities convertible into or exercisable or exchangeable for Common Units except that the Partnership may issue Common Units or any securities convertible or exchangeable into Common Units as payment of any part of the purchase price for businesses that are acquired by the Partnership; provided that any recipient of such Common Units must agree in writing to be bound by the terms of this Section 5(k) for the remaining term of the 180-day restricted period,, (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or such other securities, in cash or otherwise, (3) file any registration statement with the Commission relating to the offering of any Common Units or any securities convertible into or exercisable or exchangeable for Common Units, or (4) publicly announce an intention to effect any transaction specified in clause (1), (2) or

(3). The foregoing sentence shall not apply to (a) transactions relating to Common Units or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) shall be required or shall be voluntarily made in connection with subsequent sales of Common Units or other securities acquired in such open market transactions, (b) transfers of Common Units or any security convertible into Common Units as a bona fide gift, (c) transfers by will or intestate succession to the undersigned’s family or to a trust, the beneficiaries of which are exclusively the undersigned or members of the undersigned’s family, (d) pro rata distributions of Common Units or any security convertible into Common Units to limited partners or unitholders of the undersigned, or (e) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act; provided that in the case of any transfer or distribution pursuant to clause (b), (c) or (d), (i) each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of Common Units, shall be required or shall be voluntarily made during the restricted period referred to in the foregoing sentence. In addition, the undersigned agrees that, without the prior written consent of Baird on behalf of the Underwriters, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any Common Units or any security convertible into or exercisable or exchangeable for Common Units. The undersigned also agrees and consents to the entry of stop transfer instructions with the Partnership’s transfer agent and registrar against the transfer of the undersigned’s Common Units except in compliance with the foregoing restrictions.

If:

(1) during the last 17 days of the Restricted Period the Partnership issues an earnings release or material news or a material event relating to the Partnership occurs; or

(2) prior to the expiration of the Restricted Period, the Partnership announces that it will release earnings results during the 16-day period beginning on the last day of the restricted period;

then the restrictions imposed by this agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

The undersigned shall not engage in any transaction that may be restricted by this agreement during the 34-day period beginning on the last day of the Restricted Period unless the undersigned requests and receives prior written confirmation from the Partnership or Baird that the restrictions imposed by this agreement have expired.

The undersigned understands that the Partnership and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Partnership and the Underwriters.

Very truly yours,
