EV Energy Partners, L.P., a Delaware limited partnership (the “Partnership”) and EV Energy Finance Corp., a Delaware corporation (“Finance Corp”) propose to issue and sell to the several Underwriters listed in Schedule I hereto (the “Underwriters”), for whom you are acting as a representative (the “Representative”), $200,000,000 aggregate principal amount of their 8.0% Senior Notes due 2019 (the “Notes”). The Partnership and Finance Corp are referred to collectively as the “Issuers.” The Notes will be issued pursuant to an Indenture dated as of March 22, 2011 (the “Indenture”) among the Partnership, Finance Corp, the guarantors listed in Schedule II hereto (the “Guarantors”) and U.S. Bank National Association, as trustee (the “Trustee”), and will be guaranteed on an unsecured senior basis by each of the Guarantors (the “Guarantees” and, together with the Notes, the “Securities”).

The Notes constitute “Additional Notes” (as defined in Section 1.01 of the Indenture) under the Indenture. The Issuers have previously issued $300,000,000 aggregate principal amount of their 8.0% Senior Notes due 2019 (the “Existing Notes”) under the Indenture. Except as otherwise disclosed in the Disclosure Package and the Final Prospectus, the Notes will have terms identical to the Existing Notes, and the Notes and the Existing Notes will be treated as a single series of debt securities for all purposes under the Indenture.

The Issuers and the Guarantors are herein collectively referred to as the “EVEP Parties”. Each of the EVEP Parties, EV Energy GP, L.P., a Delaware limited partnership and general partner of the Partnership (the “General Partner”), and EV Management, LLC, a Delaware limited liability company and general partner of the General Partner (“GP LLC”) are referred to collectively herein as the “Partnership Entities.”

The EVEP Parties confirm their agreement with the several Underwriters concerning the purchase and sale of the Notes, as follows:

The Issuers will not be obligated to deliver any of the Notes except upon payment for all the Notes to be purchased as provided herein.

(b) The Issuers understand that the Underwriters intend to make a public offering of the Notes as soon after the effectiveness of this Agreement as in the judgment of the Representative is advisable, and initially to offer the Notes on the terms set forth in the Disclosure Package and the Prospectus. The Issuers acknowledge and agree that the Underwriters may offer and sell Notes to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Notes purchased by it to or through any Underwriter.

Additionally, neither the Representative nor any other Underwriter is advising any EVEP Party or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The EVEP Parties shall consult with their own advisors concerning such matters and shall be responsible for making their own independent investigation and appraisal of the transactions contemplated hereby, and neither the Representative nor any other Underwriter shall have any responsibility or liability to the EVEP Parties with respect thereto. Any review by the Representative or any Underwriter of any EVEP Parties, the transactions contemplated hereby or other matters relating to such transactions will be performed solely for the benefit of the Representative or such Underwriter and shall not be on behalf of the EVEP Parties or any other person

(xiv) During the period from the date hereof through and including the date that is 90 days after the date hereof, the Issuers and each of the Guarantors will not, without the prior written consent of the Representative, on behalf of the Underwriters, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by any of the EVEP Parties and having a tenor of more than one year.

(xv) The Issuers will assist the Underwriters in arranging for the Notes to be eligible for clearance and settlement through DTC.

(j) Subsequent to the execution and delivery to this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the NASDAQ shall have been suspended, the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) trading in any securities of the Partnership on any exchange or in the over-the-counter market shall have been suspended, (iii) a banking moratorium shall have been declared by federal or state authorities, (iv) the United States shall have become engaged in 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 (v) there shall have occurred such a material adverse change in general economic, political or financial conditions or any other calamity or crisis, 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), as to make it, in the judgment of the Representative, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering, issuance or sale of the Securities being delivered on such Delivery Date on the terms and in the manner contemplated in the Final Prospectus.

(ii) such EVEP Party has examined the Registration Statement, the Disclosure Package and the Final Prospectus and any amendment or supplement thereto, as well as each electronic roadshow used in connection with the offering, and nothing has come to such EVEP Party’s attention that would lead it to believe that: (A)(1) the Registration Statement, including the documents incorporated therein by reference, as of the most recent Effective Date, (2) the Final Prospectus, including any documents incorporated by reference therein, as of the date of the Final Prospectus and as of the Delivery Date, and (3) the Disclosure Package, as of the Execution Time, contained and contain any untrue statement of a material fact and omitted and 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; and (B) since the Effective Date, there has occurred any event required to be set forth in an amendment or supplement to the Registration Statement, the Final Prospectus, the Disclosure Package and any amendment or supplement thereto which has not been so set forth;

5. Indemnification and Contribution.

(a) The EVEP Parties, jointly and severally, will indemnify and hold harmless each Underwriter, the directors, officers, employees, agents and affiliates of each Underwriter, and each person who controls any Underwriter or any affiliate within the meaning of the 1933 Act or the 1934 Act, from and against any losses, damages or liabilities, joint or several, to which the Underwriters may become subject under the 1933 Act or otherwise, insofar as such losses, damages or liabilities (or actions or claims in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Final Prospectus, the Disclosure Package, any Issuer Free Writing Prospectus or any amendment or supplement thereto or (B) any Blue Sky application or other document prepared or executed by any of the Partnership Entities (or based upon any written information furnished by any of the Partnership Entities) or the omission or alleged omission to state in any Preliminary Prospectus, the Final Prospectus, the Disclosure Package, any Issuer Free Writing Prospectus or any amendment or supplement thereto a material fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, and will reimburse each of the Underwriters for any legal or other out-of-pocket expenses incurred by such Underwriter in connection with investigating, preparing, pursuing or defending against or appearing as a third party witness in connection with any such loss, damage, liability or action or claim, including, without limitation, any investigation or proceeding by any governmental agency or body, commenced or threatened, including the reasonable fees and expenses of counsel to the indemnified party, as such expenses are incurred (including such losses, damages, liabilities or expenses to the extent of the aggregate amount paid in settlement of any such action or claim, provided that (subject to Section 5(c) hereof) any such settlement is effected with the written consent of the General Partner); provided, however, that the EVEP Parties shall not be liable in any such case to the extent, but only to the extent, that any such loss, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Final Prospectus, the Disclosure Package, any Issuer Free Writing Prospectus or any amendment or supplement thereto or any Blue Sky Application, in reliance upon and in conformity with written information relating to the Underwriters furnished to the EVEP Parties by the Representative, expressly for use in the preparation thereof (as provided in Section 11 hereof).

(b) Each of the Underwriters, severally and not jointly, will indemnify and hold harmless the EVEP Parties from and against any losses, damages or liabilities to which the EVEP Parties may become subject under the 1933 Act or otherwise, insofar as such losses, damages or liabilities (or actions or claims in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or the omission or alleged omission to state therein a material fact required to be stated therein or necessary in order 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 Final Prospectus, the Disclosure Package, any Issuer Free Writing Prospectus or any amendment or supplement thereto or Blue Sky Application or the omission or alleged omission to state in any Preliminary Prospectus, the Final Prospectus, the Disclosure Package, any Issuer Free Writing Prospectus or any amendment or supplement thereto a material fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, any Preliminary Prospectus, the Final Prospectus, the Disclosure Package, any Issuer Free Writing Prospectus or any amendment or supplement thereto, in reliance upon and in conformity with written information relating to the Underwriters furnished to the Partnership by the Underwriters, expressly for use in the preparation thereof (as provided in Section 11 hereof), and will reimburse the EVEP Parties for any legal or other expenses incurred by the EVEP Parties in connection with investigating or defending any such action or claim as such expenses are incurred (including such losses, damages, liabilities or expenses to the extent of the aggregate amount paid in settlement of any such action or claim, provided that (subject to Section 5(c) hereof) any such settlement is effected with the written consent of the Underwriters).

(c) Promptly after receipt by an indemnified party under Section 5(a) or 5(b) hereof of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under Section 5(a) or 5(b) hereof, notify each such indemnifying party in writing of the commencement thereof, but the failure so to notify such indemnifying party shall not relieve such indemnifying party from any liability it may have under Section 5(a) or 5(b) hereof except to the extent that it has been prejudiced in any material respect by such failure, and such failure shall not relieve such indemnifying party from any liability that it may have to any such indemnified party otherwise than under Section 5(a) or 5(b) hereof. In case any such action shall be brought against any such indemnified party and it shall notify each indemnifying party of the commencement thereof, each such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party under Section 5(a) or 5(b) hereof similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of such indemnified party, be counsel to such indemnifying party), and, after notice from such indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party under Section 5(a) or 5(b) hereof for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. The indemnified party shall have the right to employ its own counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party at the expense of the indemnifying party has been authorized by the indemnifying party, (ii) the indemnified party shall have been advised by such counsel that there may be a conflict of interest between the indemnifying party and the indemnified party in the conduct of the defense, or certain aspects of the defense or that the indemnified party may have different available defenses, of such action (in which case the indemnifying party shall not have the right to direct the defense of such action with respect to those matters or aspects of the defense on which a conflict exists or may exist on behalf of the indemnified party) or (iii) the indemnifying party shall not in fact have employed counsel reasonably satisfactory to such indemnified party to assume the defense of such action, in any of which events such fees and expenses to the extent applicable shall be borne, and shall be paid as incurred, by the indemnifying party. If at any time such indemnified party shall have requested such indemnifying party under Section 5(a) or 5(b) hereof to reimburse such indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 5(a) or 5(b) hereof effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of such request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request for reimbursement prior to the date of such settlement. No such indemnifying party shall, without the written consent of such indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not such indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (A) includes an unconditional release of such indemnified party from all liability arising out of such action or claim and (B) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any such indemnified party. In no event shall such indemnifying parties be liable for the fees and expenses of more than one counsel, other than one local counsel, for all such indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances.

(d) If the indemnification provided for in this Section 5 is unavailable to or insufficient to indemnify or hold harmless an indemnified party under Section 5(a) or 5(b) hereof in respect of any losses, damages or liabilities (or actions or claims in respect thereof) referred to therein, then each indemnifying party under Section 5(a) or 5(b) hereof shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages or liabilities (or actions or claims in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the EVEP Parties, on the one hand, and the Underwriters, on the other hand, from the offering of the Securities. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under Section 5(c) hereof and such indemnifying party was prejudiced in a material respect by such failure, then each such indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault, as applicable, of the EVEP Parties, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, damages or liabilities (or actions or claims in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by, as applicable, the EVEP Parties, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Partnership bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault, as applicable, of the EVEP Parties, 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 EVEP Parties, on the one hand, or the Underwriters, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The EVEP Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 5(d). The amount paid or payable by such an indemnified party as a result of the losses, damages or liabilities (or actions or claims in respect thereof) referred to above in this Section 5(d) shall be deemed to include any legal or other expenses incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 5(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Securities 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 0000 Xxx) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 5(d) are several in proportion to their respective purchase obligations and not joint.

(e) The obligations of the EVEP Parties under this Section 5 shall be in addition to any liability that the EVEP Parties may otherwise have and shall extend, upon the same terms and conditions, to each officer, director, employee, agent or other representative and to each person, if any, who controls any Underwriter within the meaning of the 1933 Act; and the obligations of each of the Underwriters under this Section 5 shall be in addition to any liability that the respective Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Partnership and the General Partner who signed the Registration Statement and to each person, if any, who controls the EVEP Parties within the meaning of the 1933 Act.

6. Representations and Agreements to Survive Delivery. The respective representations, warranties, agreements and statements of the EVEP Parties and the Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain operative and in full force and effect regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, the EVEP Parties or any of their officers, directors or any controlling persons and shall survive delivery of and payment for the Securities hereunder.

7. Defaulting Underwriter. If, on the Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the principal amount of the Notes that the defaulting Underwriter agreed but failed to purchase on the Delivery Date in the respective proportions that the principal amount of the Notes set forth opposite the name of each remaining non-defaulting Underwriter in Schedule I hereto bears to the aggregate principal amount of the Notes set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule I hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Notes on the Delivery Date if the aggregate principal amount of the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the aggregate principal amount of the Notes to be purchased on such Delivery Date and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the principal amount of the Notes that it agreed to purchase on such Delivery Date pursuant to the terms of Section 1. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Underwriters who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, the aggregate principal amount of the Notes to be purchased on the Delivery Date. If the remaining Underwriters, or other underwriters satisfactory to the Underwriters, do not elect to purchase the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase on the Delivery Date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or any EVEP Party except that the Partnership will continue to be liable for the payment of expenses to the extent set forth in Section 9. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule I hereto who, pursuant to this Section 7, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Partnership for damages caused by its default. If other Underwriters are obligated or agree to purchase the Notes of a defaulting or withdrawing Underwriter, either the Underwriters or the Partnership may postpone such Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Disclosure Package, the Final Prospectus or in any other document or arrangement.

8. Termination. This Agreement may be terminated by the Representative on behalf of the Underwriters at any time at or prior to the Delivery Date by notice to the Partnership if any condition specified in Section 4 hereof shall not have been satisfied on or prior to the Delivery Date. Any such termination shall be without liability of any party to any other party except as provided in Sections 5 and 9 hereof. If the Representative on behalf of the Underwriters terminates this Agreement as provided in this Section 8, it shall notify the Partnership by telephone or telegram, confirmed by letter.
