facilities of DTC. Delivery of the documents required by Section 7 hereof with
respect to the Units shall be made at the Place of Closing at or prior to 11:00

Underwriters such representations, warranties, agreements, opinions, letters,
certificates and covenants with respect to the Option Units as are required to

      sold any Units by means of any "prospectus" (within the meaning of the
      Act) or used any "prospectus" (within the meaning of the Act) in
      connection with the offer or sale of the Units, in each case other than
      the Preliminary Prospectuses and the Permitted Free Writing Prospectuses,
      if any; the Partnership has not, directly or indirectly, prepared, used or
      referred to any Permitted Free Writing Prospectus except in compliance
      with Rules 164 and 433 under the Act; assuming that such Permitted Free
      Writing Prospectus is so sent or given after the Registration Statement
      was filed with the Commission (and after such Permitted Free Writing
      Prospectus was, if required pursuant to Rule 433(d) under the Act, filed
      with the Commission), the sending or giving, by any Underwriter, of any
      Permitted Free Writing Prospectus will satisfy the provisions of Rule 164
      and Rule 433 (without reliance on subsections (b), (c) and (d) of Rule
      164); each of the Preliminary Prospectuses is a prospectus that, other
      than by reason of Rule 433 under the Act, satisfies the requirements of
      Section 10 of the Act, including a price range where required by rule;
      neither the Partnership nor the Underwriters are disqualified, by reason
      of subsection (f) or (g) of Rule 164 under the Act, from using, in
      connection with the offer and sale of the Units, "free writing
       prospectuses" (as defined in Rule 405 under the Act) pursuant to Rules 164
      and 433 under the Act; the Partnership is not an "ineligible issuer" (as
      defined in Rule 405 under the Act) as of the eligibility determination
      date for purposes of Rules 164 and 433 under the Act with respect to the
      Offering contemplated by the Registration Statement; the parties hereto
      agree and understand that the content of any and all "road shows" (as
      defined in Rule 433(h) under the Act) related to the Offering is solely
      the property of the Partnership; the Partnership has caused there to be
      made available at least one version of a "bona fide electronic road show"
      (as defined in Rule 433(h)(5) under the Act) in a manner that, pursuant to
      Rule 433(d)(8)(ii) under the Act, causes the Partnership not to be
      required, pursuant to Rule 433(d) under the Act, to file with the
      Commission any road show.

            (c) Other Sales. The Partnership has not sold or issued any Units
      during the six-month period preceding the date of the Preliminary
      Prospectus, other than pursuant to acquisitions, employee benefit plans,
      qualified options plans or other employee compensation plans or pursuant
      to outstanding options, rights or warrants described in the Disclosure
      Package and the Prospectus.

            (d) Formation and Due Qualification. Formation and Due
      Qualification. Each of the Partnership Entities has been duly formed or
      incorporated and is validly existing as a limited partnership or limited
      liability company, as the case may be, in good standing under the laws of
      its respective jurisdiction of formation or incorporation, and is, or at
      the Closing Date will be, duly registered or qualified to do business and
      is in good standing as a foreign limited partnership or foreign limited
      liability company, as the case may be, in each jurisdiction in which its
      ownership or lease of property or the conduct of its businesses requires
      such registration or qualification, except where the failure so to
      register or qualify would not (i) have a material adverse effect on the
      consolidated financial position, partners' or members' equity, results of
      operations, business or prospects of the Partnership Entities taken as a
      whole (a "Material Adverse Effect") or (ii) subject the limited partners
      of the Partnership to any material liability or disability, as

                                        10

      set forth under its name on Schedule II to this Agreement. Each of the
      Partnership Entities has all limited partnership or limited liability
      company, as the case may be, power and authority necessary to own or lease
      its properties currently owned or leased or to be owned or leased at the
      Closing Date, to assume the liabilities assumed or being assumed by it
      pursuant to the Transaction Documents and to conduct its business as
      currently conducted and as to be conducted at the Closing Date, in each
      case in all material respects as described in the Prospectus.

            (e) Ownership of the General Partner Interest in the Partnership. At
      the Closing Date and the Option Closing Date, after giving effect to the
      Transactions, the General Partner will be the sole general partner of the
      Partnership with a 2% general partner interest in the Partnership. Such
      general partner interest will be duly authorized and validly issued in
      accordance with the partnership agreement of the Partnership (as the same
      may be amended or restated at or prior to the Closing Date, the
      "Partnership Agreement") and will be fully paid (to the extent required
      under the Partnership Agreement) and nonassessable (except as such
      nonassessability may be affected by Section 17-303 and 17-607 of the
      Delaware Revised Uniform Limited Partnership Act (the "Delaware LP Act")),
      and the General Partner will own such general partner interest free and
      clear of all liens, encumbrances (except restrictions on transferability
      described in the Prospectus), security interests, equities, charges or
      claims.

            (f) Ownership of Sponsor Units and the Incentive Distribution

      distribution rights in the Partnership (as defined in the Partnership
      Agreement, the "Incentive Distribution Rights"); all of such Sponsor Units
      and Incentive Distribution Rights and the limited partner interests
      represented thereby will be duly authorized and validly issued in
      accordance with the Partnership Agreement, and will be fully paid (to the
      extent required under the Partnership Agreement) and nonassessable (except
      as such nonassessability may be affected by Sections 17-303 and 17-607 of
      the Delaware LP Act and as otherwise described in the Prospectus under the
      caption "The Partnership Agreement--Limited Liability," "Risk
      Factors--Risks Inherent in an Investment in Us--Your liability may not be
      limited if a court finds that unitholder action constitutes control of our
      business" and "Risk Factors--Risks Inherent in an Investment in
      Us--Unitholders may have liability to repay distributions that were

      delivered to the Underwriters against payment therefor in accordance with
      the terms hereof will be validly issued, fully paid (to the extent
      required under the Partnership Agreement) and nonassessable (except as
      such nonassessability may be affected by Sections 17-303 and 17-607 of the
      Delaware LP Act and as otherwise described in the Prospectus under the
      caption "The Partnership Agreement--Limited Liability," "Risk
      Factors--Risks Inherent in an Investment in Us--Your liability may not be

      Us--Unitholders may have liability to repay distributions that were

      Entities (other than liens created under the Credit Facility), which
      conflicts, breaches, violations, defaults or liens, in the case of clauses
      (ii), (iii) or (iv), would, individually or in the aggregate, have a

      the Partnership Entities to perform their obligations under this Agreement
      or the Operative Agreements.

            (s) No Consents. No permit, consent, approval, authorization, order,
      registration, filing or qualification ("Consent") of or with any court,

      incorporation, bylaws or other constituent document, (ii) in violation of
      any law, statute, ordinance, administrative or governmental rule or
      regulation applicable to it or of any order, judgment, decree or
      injunction of any court or governmental agency or body having jurisdiction
      over it or (iii) in breach, default (or an event which, with notice or
      lapse of time or both, would constitute such a default) or violation in
      the performance of any obligation, agreement or condition contained in any
      bond, debenture, note or any other evidence of indebtedness or in any
      agreement, indenture, lease or other instrument to which it is a party or
      by which it or any of its properties may be bound, which breach, default
      or violation in the case of clause (ii) or (iii) would, if continued, have
      a Material Adverse Effect or materially impair the ability of any of the
      Partnership Entities to perform their obligations under this Agreement or
      the Operative Agreements. To the knowledge of the EVEP Parties, no third
      party to any indenture, mortgage, deed of trust, loan agreement or other
      agreement or instrument to which any of the Partnership Entities is a
      party or by which any of them is bound or to which any of their properties
      is subject, is in breach, default or violation of any such agreement,

      terms of the Partnership Agreement, will conform in all material respects
      to the descriptions thereof contained in the Registration Statement, the
      Prospectus and the Disclosure Package.

            (v) Independent Public Accountants. The accountants, Deloitte &
      Touche LLP, who have certified or shall certify the audited financial
      statements included in the Registration Statement, the Preliminary
      Prospectus and the Prospectus (or any amendment or supplement thereto),
      were independent registered public accountants with respect to the
      Partnership and the General Partner as required by the 1933 Act and the
       1933 Act Rules and Regulations during the periods covered by the financial
      statements on which they reported.

            (w) Financial Statements. As of June 30, 2006, the Partnership would
      have had, on the consolidated pro forma basis indicated in the Prospectus

      therein. The historical financial statements (including the related notes
      and supporting schedules) included in the Registration Statement, the
      Preliminary Prospectus and the Prospectus, together with the related notes
      (and any amendment or supplement thereto) comply as to form in all
      material respects with the requirements of Regulation S-X under the 1933

      operations and cash flows of the entities purported to be shown thereby on
      the basis stated therein at the respective dates or for the respective
      periods to which they apply and have been prepared in accordance with

      Registration Statement, the Preliminary Prospectus and the Prospectus (and
      any amendment or supplement thereto) have been prepared in all material
      respects in accordance with the applicable requirements of Article 11 of
      Regulation S-X of the Commission; the assumptions used in the preparation
      of such pro forma financial statements are, in the opinion of the
      management of the General Partner, reasonable; and the pro forma
      adjustments reflected in such pro forma financial statements have been
      properly applied to the historical amounts in compilation of such pro
      forma financial statements. There are no financial statements (historical
      or pro forma) that are required to be included in the Registration
      Statement, the Prospectus and the Disclosure Package that are not included
      as required.

      the right, in all material respects, to explore, develop or produce
      hydrocarbons as described, and subject to the limitations contained, in
      the Registration Statement, the Prospectus and the Disclosure Package. The
      care taken by the Partnership Entities in acquiring or otherwise procuring
      such leases or mineral interests was generally consistent with standard
      industry practices in the areas in which the Partnership Entities operate
      for acquiring or procuring leases and interests therein to explore,

            (z) Information Underlying Reserve Report. The factual information
      underlying the estimates of pro forma reserves of the Partnership

      Prospectus, including, without limitation, production volumes, costs of
       operation and development, current prices for production, agreements
      relating to current and future operations and sales of production, was
      true and correct in all material respects on the dates such estimates were
      made and such information was supplied and was prepared in accordance with
      customary industry practices; other than normal production of the reserves
      and intervening market commodity price fluctuations, the Partnership
      Entities are not aware of any facts or circumstances that would result in
      a material adverse change in the reserves, or the present value of future
      net cash flows therefrom, as described in the Prospectus and as reflected
      in the Reserve Report Letter; estimates of such reserves and present
      values as described in the Pricing Prospectus and reflected in the Reserve
      Report Letter comply in all material respects with the applicable

      Act.

      Package, any material loss or interference with its business from fire,
      explosion, flood or other calamity, whether or not covered by insurance,
      or from any labor dispute or court or governmental action, investigation,
      order or decree, otherwise than as set forth or contemplated in the
      Registration Statement, the Prospectus and the Disclosure Package. Except
      as disclosed in the Registration Statement, the Prospectus and the
      Disclosure Package (or any amendment or supplement thereto), subsequent to
      the respective dates as of which such information is given in the
      Registration Statement, the Prospectus and the Disclosure Package (or any
      amendment or supplement thereto), (i) none of the Partnership Entities has
      incurred any liability or obligation, indirect, direct or contingent, or
      entered into any transactions, not in the ordinary course of business,
      that, singly or in the aggregate, is material to the Partnership Entities,
      (ii) there has not been any material change in the capitalization, or
      material increase in the short-term debt or long-term debt, of any
      Partnership Entity and (iii) there has not been any material adverse
      change, or any development involving or which may reasonably be expected
      to involve, singly or in the aggregate, a prospective material adverse
      change in or affecting the general affairs, business, prospects,
      properties, management, condition (financial or other), partners' equity,
      members' equity, net worth or results of operations of the Partnership
      Entities.

      is not so described. There are no outstanding loans, advances (except
      normal advances for business expenses in the ordinary course of business)
      or guarantees of indebtedness by any Partnership Entity to or for the
      benefit of any of the officers, directors or managers of any Partnership

      Registration Statement, the Prospectus and the Disclosure Package. No
      Partnership Entity has, in violation of the Sarbanes-Oxley Act of 2002,
      directly or indirectly, extended or maintained credit, arranged for the
      extension of credit or renewed an extension of credit, in the form of a
      personal loan to or for any director, manager or executive officer of any
      Partnership Entity.

            (dd) Rights-of-Way. Upon consummation of the Transactions on the
      Closing Date, each of the Partnership Entities will have such easements,
      rights-of-way, permits or licenses (collectively, "rights-of-way") and
      consents with respect to the transfer of any of the foregoing, as are
      necessary to conduct its business in the manner described, and subject to
      the limitations contained, in the Registration Statement, the Prospectus
      and the Disclosure Package, except for (i) qualifications, reservations
      and encumbrances that would not have a Material Adverse Effect and (ii)

      Partnership Entities has, or upon consummation of the Transactions at the
      Closing Date will have, fulfilled and performed all of its material
      obligations with respect to such rights-of-way or consents and no event
      has occurred that allows, or after notice or lapse of time would allow,
      revocation or termination thereof or would result in any impairment of the
      rights of the holder of any such rights-of-way or consents, except for
      such revocations, terminations and impairments that would not have a
      Material Adverse Effect; and, except as described in the Registration
      Statement, the Prospectus and the Disclosure Package, none of such
      rights-of-way or consents contains any restriction that is materially
      burdensome to the business of the Partnership Entities, taken as a whole.

            (ee) Sufficiency of Contribution Documents. The Contribution

      not already held by them that are, individually or in the aggregate,
      required to enable the Partnership and the Subsidiaries to conduct their
      operations (in all material respects as contemplated by the Prospectus),
      subject to the conditions, reservations and limitations contained in the
      Contribution Documents and those set forth in the Prospectus. The
      Operating Subsidiaries, upon execution and delivery of the Contribution
      Documents, succeeded or will succeed in all material respects to the
      business, assets, properties, liabilities and operations reflected by the
      pro forma financial statements of the Partnership included in the
      Prospectus, except as disclosed in the Prospectus and the Contribution
      Documents.

            (ff) Permits. Each of the Partnership Entities has, or at the
      Closing Date will have, such permits, consents, licenses, franchises,
      certificates and authorizations of governmental or regulatory authorities
      ("permits") as are necessary to own its properties and to conduct its
      business in the manner described in the Disclosure Package and the
      Prospectus, subject to such qualifications as may be set forth in the
      Disclosure Package and the Prospectus and except for such permits that, if
      not obtained, would not, individually or in the aggregate, have a Material
      Adverse Effect; except as set forth in the Registration Statement, the
      Prospectus and the Disclosure Package, each of the Partnership Entities
      has, or at the Closing Date will have, fulfilled and performed all its
      material obligations with respect to such permits which are or will be due
      to have been fulfilled and performed by such date and no event has
      occurred that would prevent the permits from being renewed or reissued or
      which allows, or after notice or lapse of time would allow, revocation or
      termination thereof or results in any impairment of the rights of the
      holder of any such permit, except for such non-renewals, non-issuances,
      revocations, terminations and impairments that would not, individually or
      in the aggregate, have a Material Adverse Effect.

      books, records and accounts, which, in reasonable detail, accurately and

      consolidated subsidiaries, is made known to the General Partner's

      obtained extensions with respect to) all material federal, state, local
      and foreign income and franchise tax returns required to be filed through
      the date hereof, which returns are complete and correct in all material
      respects, and has timely paid all taxes due thereon, other than those (i)
      which are being contested in good faith and for which adequate reserves

      with the terms and conditions of such permits or liability would not,
      individually or in the aggregate, have a Material Adverse Effect. The term

      insurance covering the properties, operations, personnel and businesses of
      the Partnership Entities against such losses and risks and in such amounts
      as is reasonably adequate for the conduct of their respective businesses
      and the value of their respective properties and as

                                       21
<PAGE>

      is customary for companies engaged in similar businesses in similar
      industries. None of the Partnership Entities, EVMP or EVOC has received

      reasonably likely to (A) individually or in the aggregate have a Material

      issuance or sale of the Units, or (C) in any manner draw into question the
      validity of this Agreement.

            (pp) No Distribution of Other Offering Materials. None of the
      Partnership Entities have distributed and, prior to the later to occur of
      (i) the Closing Date and (ii) completion of the distribution of the Units,
      will not distribute, any prospectus (as defined under the 1933 Act) in

      the customer's or supplier's level or type of business with the
      Partnership Entities, or (ii) a trade journalist or publication to write
      or publish favorable information about the Partnership Entities or their
      products or services.

            (ss) Brokers. Except as described in the Prospectus, there are no

      Entity or any Underwriter for a brokerage commission, finder's fee or
      other like payment in connection with this offering of the Units.

            (tt) Market Stabilization. None of the Partnership Entities (i) has
      taken, and none of such persons shall take, directly or indirectly, any
      action designed to cause or

                                       22
<PAGE>

      result in, or which has constituted or which might reasonably be expected
      to constitute, the stabilization or manipulation of the price of the Units
      to facilitate the sale or resale of the Units in violation of any law,
      rule or regulation or (ii) since the initial filing of the Registration
       Statement, except as contemplated by this Agreement, (A) has sold, bid
      for, purchased or paid anyone any compensation for soliciting purchases of
      the Units or (B) has paid or agreed to pay to any person any compensation

      market-related data included in the Registration Statement, the
      Preliminary Prospectuses, and the Disclosure Package, if any, are based on

      reliable and accurate, and the Partnership has obtained the written
      consent to the use of such data from such sources to the extent required.

            (vv) NASD Affiliations. To the Partnership's knowledge, there are no
      affiliations or associations between any member of the National
      Association of Securities Dealers, Inc. ("NASD") and any of the
      Partnership's officers or directors or the Partnership's 5% or greater
      securityholders, except as set forth in the Registration Statement, the
      Preliminary Prospectuses and the Prospectus.

      Any certificate signed by any officer of any Partnership Entity or EVMP
and delivered to the Underwriters or to counsel for the Underwriters pursuant to
this Agreement shall be deemed a representation and warranty by such Partnership
Entity or EVMP to each Underwriter as to the matters covered thereby.

      6.     ADDITIONAL COVENANTS.

            (a) The EVEP Parties (but not including the EnCap Entities) jointly
      and severally covenant and agree with the several Underwriters with
      respect to the provisions of this Section 6(a), and the EnCap Entities
      severally as to themselves only covenant and agree with the several
      Underwriters with respect to Section 6(a)(xiii) solely as such section
      relates to the EnCap Entities, that:

                  (i) The Partnership will timely transmit copies of the
            Prospectus in a form approved by the Underwriters, and any
            amendments or supplements thereto (subject to the provisions of this
            Section 5), to the SEC for filing pursuant to Rule 424(b) of the
            1933 Act Rules and Regulations or, if applicable, Rule 430A(a)(3) of
            the 1933 Act Rules and Regulations.

            exhibits thereto, of any amendments and supplements to the
            Registration Statement and (ii) a signed copy of each consent and
            certificate included in, or filed as an exhibit to, the Registration
            Statement as so amended or supplemented; the Partnership will
            deliver to the Underwriters as soon as practicable after the date of
            this Agreement as many copies of the Preliminary Prospectus,
            Prospectus and any amendment or supplement thereto as

                                       23
<PAGE>

            the Underwriters may reasonably request for the purposes
            contemplated by the 1933 Act; if there is a post-effective amendment
            to the Registration Statement that is not effective under the 1933
            Act, the Partnership will use its best efforts to cause the
            post-effective amendment to the Registration Statement to become
            effective as promptly as possible, and it will notify the
            Underwriters, promptly after it shall receive notice thereof, of the
            time when the post-effective amendment to the Registration Statement
            has become effective; the Partnership will promptly advise the
            Underwriters of any request of the SEC for amendment of the
            Registration Statement or for supplement to the Prospectus or for
            any additional information, and of the issuance by the SEC or any
            state or other jurisdiction or other regulatory body of any stop
            order under the 1933 Act or other order suspending the effectiveness
            of the Registration Statement (as amended or supplemented) or
            preventing or suspending the use of the Preliminary Prospectus, any
            Permitted Free Writing Prospectus or the Prospectus or suspending
            the qualification or registration of the Units for offering or sale
             in any jurisdiction, and of the institution or threat of any
            proceedings therefor, of which the Partnership shall have received
            notice or otherwise have knowledge prior to the completion of the
            distribution of the Units; and the Partnership will use its best
            efforts to prevent the issuance of any such stop order or other
            order and, if issued, to secure the prompt removal thereof.

                  (iii) The Partnership will not file any amendment or
            supplement to the Registration Statement, the Prospectus, Permitted
            Free Writing Prospectus or any other free writing prospectus (or any

             of the 1933 Act Rules and Regulations that differs from the
            Prospectus as filed pursuant to such Rule 424(b)), of which the
            Underwriters shall not previously have been advised or to which the
            Underwriters shall have reasonably objected in writing after being
            so advised unless the Partnership shall have determined based upon
            the advice of counsel that such amendment or supplement is required
            by law; and the Partnership will promptly notify the Underwriters
            after it shall have received notice thereof of the time when
