SECTION 1.  Description of Securities.  The Partnership proposes to issue and sell through or to the Manager, as sales agent and/or principal, the Partnership’s common units representing limited partner interests of the Partnership (the “Common Units”), having an aggregate gross sales price of up to $100,000,000 (the “Maximum Amount” and such Common Units hereinafter referred to as the “Units”) on the terms set forth in Section 3 of this Agreement.  The Partnership agrees that whenever it determines to sell the Units directly to the Manager as principal, it will enter into a separate agreement (each, a “Terms Agreement”), in form and substance satisfactory to the Manager, relating to such sale in accordance with Section 3 of this Agreement.

The Partnership has also entered into an Equity Distribution Agreement (the “Alternative Agreement”), dated as of even date herewith, with Knight Capital Americas, L.P. (the “Alternative Manager” and together with the Manager, the “Sales Managers”).  This Agreement and the Alternative Agreement are hereinafter referred to collectively as the “Sales Agreements.”  The aggregate gross sales price of the Units that may be sold pursuant to the Sales Agreements shall not exceed the Maximum Amount.

SECTION 2.  Representations and Warranties of the Partnership.  The Partnership represents and warrants to and agrees with the Manager that:

(a)                                       The Partnership meets the requirements for use of a registration statement on Form S-3 (the “registration statement”) in respect of the Units, including a form of prospectus, that was prepared and filed by the Partnership (File No. 333-163554) and became effective on March 30, 2010, in conformity with the requirements of the Securities Act of 1933, as amended, and the rules and regulations thereunder (collectively called the “Act”), and the rules and regulations of the Securities and Exchange Commission (the “Commission”) thereunder (the “Rules and Regulations”).  The Commission has not issued an order preventing or suspending the use of the Basic Prospectus (as defined below), the Prospectus Supplement (as defined below), the Prospectus (as defined below) or any Permitted Free Writing Prospectus (as

defined below), or the effectiveness of the Registration Statement (as defined below), and no proceeding for that purpose or pursuant to Section 8A of the Act has been instituted or, to the Partnership’s knowledge, threatened by the Commission.  Except where the context otherwise requires, “Registration Statement,” as used herein, means the registration statement, as amended at the time of such registration statement’s most recent effective date for purposes of Section 11 of the Act, as such section applies to the Manager, as well as any new registration statement, post-effective amendment or new shelf registration statement as may have been filed pursuant to Sections 4(f) or (g) of this Agreement, including (1) all documents filed as exhibits thereto or incorporated or deemed to be incorporated by reference therein; (2) any information contained or incorporated by reference in a prospectus filed with the Commission pursuant to Rule 424(b) under the Act, to the extent such information is deemed, pursuant to Rule 430B or Rule 430C under the Act, to be part of the registration statement at the time of such registration statement’s effectiveness for purposes of Section 11 of the Act, as such section applies to the Manager; and (3) any registration statement filed to register the offer and sale of Units pursuant to Rule 462(b) under the Act.  Except where the context otherwise requires, “Basic Prospectus,” as used herein, means the base prospectus filed as part of each Registration Statement, together with any amendments or supplements thereto.  Except where the context otherwise requires, “Prospectus Supplement,” as used herein, means the final prospectus supplement, relating to the Units, filed by the Partnership with the Commission pursuant to Rule 424(b) under the Act on or before the second business day after the date hereof (or such earlier time as may be required under the Act), in the form furnished by the Partnership to the Manager in connection with the offering of the Units.  Except where the context otherwise requires, “Prospectus,” as used herein, means the Prospectus Supplement together with the Basic Prospectus attached to or used with the Prospectus Supplement.  Notwithstanding the foregoing, if any revised basic prospectus, prospectus supplement or prospectus shall be provided to the Manager by the Partnership for use in connection with the offering and sale of the Units which differs from the Basic Prospectus, Prospectus Supplement or Prospectus, as the case may be (whether or not such revised basic prospectus, prospectus supplement or prospectus is required to be filed by the Partnership pursuant to Rule 424(b) of the Act), the terms “Basic Prospectus,” “Prospectus Supplement” and “Prospectus” shall refer to such revised basic prospectus, prospectus supplement or prospectus, as the case may be, from and after the time it is first provided to the Manager for such use.  “Permitted Free Writing Prospectuses,” as used herein, means the documents listed on Schedule A attached hereto and any other “issuer free writing prospectus” (as defined in Rule 433 of the Act) that the Partnership and the Manager shall agree from time to time is a Permitted Free Writing Prospectus.  Any reference herein to the registration statement, the Registration Statement, the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus shall be deemed to refer to and include the documents, if any, incorporated by reference, or deemed to be incorporated by reference, therein (the “Incorporated Documents”), including, unless the context otherwise requires, the documents, if any, filed as exhibits to such Incorporated Documents.  Any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Basic Prospectus, the Prospectus Supplement, the Prospectus or any Permitted Free Writing Prospectus shall be deemed to refer to and include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (collectively, the “Exchange Act”) on or after the initial effective date of the Registration Statement, or the date of the Basic

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; the estimates of such reserves and standardized measure thereof as described in the Registration Statement, the Prospectus and any Permitted Free Writing Prospectus and future net cash flow reflected in the reserve report of Cawley, Gillespie & Associates, Inc. regarding the Partnership’s reserves has been prepared in a manner that complies with the applicable requirements of the Rules and Regulations; and other than normal production of the reserves, intervening market commodity price fluctuations, fluctuations in demand for such products, adverse weather conditions, unavailability or increased costs of rigs, equipment, supplies or personnel, the timing of third party operations and other factors, or as otherwise described in the Registration Statement, the Prospectus and any Permitted Free Writing Prospectus, the Partnership is not aware of any facts or circumstances that would result in a material adverse change in the aggregate net reserves, or the present value of future net cash flows therefrom, as described in the Registration Statement, the Prospectus and any Permitted Free Writing Prospectus.

(bb)           Since the date of the most recent financial statements of the Partnership included or incorporated by reference in the Registration Statement, the Prospectus and any Permitted Free Writing Prospectus, (i) there has not been any change in the equity interests or outstanding indebtedness of any of the Partnership or the Subsidiaries that is material to the Partnership, or any material adverse change, or any development involving a prospective material adverse change, in or affecting the business, properties, management, financial position, partners’ equity, results of operations or prospects of the Partnership or the Subsidiaries, taken as a whole; (ii) the Partnership and the Subsidiaries have not entered into any transaction or agreement (other than in the ordinary course of business) that, singly or in the aggregate, is material to the Partnership or the Subsidiaries, taken as a whole, or incurred any liability or obligation, direct or contingent, that is material to the Partnership or the Subsidiaries, taken as a whole (other than in the ordinary course of business); and (iii) the Partnership and the Subsidiaries have not sustained 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 disturbance or dispute or any action, order or decree of any court or arbitrator or governmental or regulatory authority, except in the case of each of clauses (i), (ii) and (iii), as otherwise disclosed in the Registration Statement, the Prospectus and any Permitted Free Writing Prospectus.

(cc)           None of the Partnership and its Subsidiaries is now, and after the sale of the Units to be sold by the Partnership hereunder and the application of the net proceeds from such sale as described in the Registration Statement and the Prospectus under the caption “Use of Proceeds” will be, an “investment company” or a company “controlled by” an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(dd)           Except as described in the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus, the Partnership and the Subsidiaries have good and marketable title to, or, with respect to properties held under lease, have valid rights to lease or otherwise use, all items of real and personal property and assets that are material to the businesses of the Partnership and the Subsidiaries, in each case free and clear of all liens,

12

of each of clauses (i) and (ii) above, for any such failure to so pay or file or deficiency that (A) is being contested in good faith and for which adequate reserves have been established in accordance with generally accepted accounting principles, or (B) would not reasonably be expected to have a Material Adverse Effect.

(ii)             The Partnership and the Subsidiaries have insurance covering their respective properties, operations, personnel and businesses, which insurance is in amounts and insures against such losses and risks as are reasonable for companies engaged in similar business in similar industries; and none of the Partnership or the Subsidiaries has (i) received notice from any insurer or agent of such insurer that capital improvements or other expenditures are required or necessary to be made in order to continue such insurance; or (ii) any reason to believe that they will not be able to renew their existing insurance coverage as and when such coverage expires or to obtain similar coverage at reasonable cost from similar insurers as may be necessary to continue their business.

(jj)             The Common Units are an “actively-traded security” excepted from the requirements of Rule 101 of Regulation M under the Exchange Act by subsection (c)(1) of such rule.

(kk)           The Partnership has established and maintains “disclosure controls and procedures” (as such term is defined in Rule 13a-15(e) under the Exchange Act), which (i) are designed to ensure that material information relating to the Partnership, including its consolidated subsidiaries, is made known to the Partnership’s principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared; (ii) have been evaluated for effectiveness as of the end of the period covered by the Partnership’s most recent Quarterly Report on Form 10-Q filed with the Commission; and (iii) are effective in all material respects to perform the functions for which they were established.

(ll)             Since the date of the most recent balance sheet of the Partnership reviewed or audited by KPMG and the audit committee of the board of directors of G&P LLC:  (i) none of the Partnership or the Subsidiaries is aware of (A) any significant deficiencies in the design or operation of internal controls that could adversely affect the ability of any such entities to record, process, summarize and report financial data that it has not notified the Manager of in writing and is not using commercially reasonable efforts to remediate, or any material weaknesses in internal controls; or (B) any fraud, whether or not material, that involves management or other employees who have a significant role in the internal controls of any such entity; and (ii) since that date, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

(mm)        The Partnership maintains systems of “internal control over financial reporting” (as defined in Rule 13a-15(f) of the Exchange Act) that comply with the requirements of the Exchange Act and have been designed by, or under the supervision of, G&P LLC’s principal executive and principal financial officers, or persons performing similar functions, to provide reasonable assurance that (i) transactions are validly executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded

13

as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accounts for assets is compared with the existing assets at reasonable intervals and appropriate action is taken with respect to any differences.

(nn)           Nothing has come to the attention of the Partnership that has caused the Partnership to believe that the statistical and market-related data included or incorporated by reference in the Registration Statement, the Prospectus or any Permitted Free Writing Prospectus are not based on or derived from sources that are reliable and accurate in all material respects.

(oo)           (i) Each employee benefit plan, within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), for which the Partnership or any member of its “controlled group” (defined as any organization which is a member of a controlled group of corporations within the meaning of Section 414 of the Internal Revenue Code of 1986, as amended (the “Code”)) would have any liability (each, a “Plan”) has been maintained in all material respects in compliance with its terms and the requirements of any applicable statutes, orders, rules and regulations, including but not limited to ERISA and the Code; (ii) to the knowledge of the Partnership, no prohibited transaction, within the meaning of Section 406 of ERISA or Section 4975 of the Code, has occurred with respect to any Plan excluding transactions effected pursuant to a statutory or administrative exemption; and (iii) no Plan is subject to Title IV of ERISA; except, in the case of each of clauses (i) and (ii) above, for any such failure to maintain or comply or the occurrence of any transaction as would not reasonably be expected to have a Material Adverse Effect.

15

Partnership and based on assumptions believed by the Partnership to be reasonable.  With respect to the Specified Historical Operating Results, nothing has come to the attention of the Partnership that causes it to believe that the financial information contained in the Specified Historical Operating Results is not true, correct and accurate in all material respects.

In addition, any certificate signed by any officer of the Partnership or any of the Subsidiaries and delivered to the Manager or counsel for the Manager in connection with the offering of the Units shall be deemed to be a representation and warranty by the Partnership, as to matters covered thereby, to the Manager.

SECTION 3.  Sale and Delivery of Securities.

(a)             On the basis of the representations, warranties and agreements herein contained, but subject to the terms and conditions herein set forth, the Partnership agrees to issue and sell through the Manager, as sales agent, and the Manager agrees to use its reasonable efforts to sell, as sales agent for the Partnership, the Units on the following terms.

(i)        The Units are to be sold on a daily basis or otherwise as shall be agreed to by the Partnership and the Manager on any day that (A) is a trading day for the NASDAQ (a “Trading Day”) (other than a trading day on which the NASDAQ is scheduled to close prior to its regular weekday closing time); (B) the Partnership has instructed the Manager by telephone (confirmed promptly by electronic mail) from any of the individuals listed as authorized representatives of the Partnership on Schedule B hereto, as updated from time to time (the “Authorized Partnership Representatives”) to make such sales; and (C) the Partnership has satisfied its obligations under Section 6 of this Agreement.  The Partnership will designate the maximum number of Units to be sold and the minimum price at which Units can be sold by the Manager daily as agreed to by the Manager and in any event not in excess of the amount of Units available for issuance under the currently effective Registration Statement.  Subject to the terms and conditions hereof, the Manager shall use its reasonable efforts to offer and sell all of the Units designated on any day; provided, however, that the Manager shall have no obligation to offer or sell any Units, and the Partnership acknowledges and agrees that the Manager shall have no such obligation, in the event an offer or sale of the Units on behalf of the Partnership may in the judgment of the Manager constitute the sale of a “block” under Rule 10b-18(a)(5) under the Exchange Act or a “distribution” within the meaning of Rule 100 of Regulation M under the Exchange Act or the Manager reasonably believes it may be deemed an “underwriter” under the Act in a transaction that is other than by means of ordinary brokers’ transactions between members of the NASDAQ that qualify for delivery of a Prospectus to the NASDAQ in accordance with Rule 153 under the Act (such ordinary brokers’ transactions are hereinafter referred to as “At the Market Offerings”).  On any Trading Day, the Partnership shall sell Units through the Manager or the Sales Manager, but in no event through both.

(ii)       Notwithstanding the foregoing, the Partnership, through any of the Authorized Partnership Representatives, may instruct the Manager by telephone (confirmed promptly by electronic mail) not to sell the Units if such sales cannot be effected at or above the price designated by the Partnership in any such instruction.  In addition, the Partnership or the Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail), suspend the offering of the Units; provided, however, that such

16

suspension shall not affect or impair the parties’ respective obligations with respect to the Units sold hereunder prior to the giving of such notice.

(iii)      The Manager hereby covenants and agrees not to make any sales of the Units on behalf of the Partnership, pursuant to this Section 3(a), other than (A) by means of At the Market Offerings and (B) such other sales of the Units on behalf of the Partnership in its capacity as agent of the Partnership as shall be agreed by the Partnership and the Manager.

(iv)      The compensation to the Manager, as an agent of the Partnership, for sales of the Units shall be 2.0% of the gross sales price of the Units sold pursuant to this Section 3(a).  The remaining proceeds, after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in connection with such sales, shall constitute the net proceeds to the Partnership for such Units (the “Net Proceeds”).

(v)       The Manager shall provide written confirmation to the Partnership following the close of trading on the NASDAQ each day in which the Units are sold under this Section 3(a) setting forth the aggregate amount of the Units sold on such day, the aggregate gross sales proceeds, any transaction fees deducted pursuant to Section 3(a)(iv), the Net Proceeds to the Partnership, and the aggregate compensation payable by the Partnership to the Manager with respect to such sales.

(vi)      Settlement for sales of the Units pursuant to this Section 3(a) will occur on the third Trading Day following the date on which such sales are made (provided that, if such third Trading Day is not a business day (as defined below), then settlement will occur on the next succeeding trading day that is also a business day), unless another date shall be agreed upon by the Partnership and the Manager (each such date, a “Settlement Date”).  As used in the preceding sentence and in Section 7 below, the term “business day” means any day other than a Saturday, Sunday or other day on which commercial banks in The City of New York are authorized or required by law, regulation or executive order to close.  On each Settlement Date, the Units sold through the Manager for settlement on such date shall be issued and delivered by the Partnership to the Manager against payment of the Net Proceeds for the sale of such Units.  Settlement for all such Units shall be effected by free delivery of the Units by the Partnership or its transfer agent to the Manager’s account, or to the account of the Manager’s designee, at The Depository Trust Company (“DTC”) through its Deposit and Withdrawal at Custodian System (“DWAC”) or by such other means of delivery as may be mutually agreed upon by the parties hereto, which in all cases shall be freely tradable, transferable, registered Common Units eligible for delivery through DTC, in return for payments in same day funds delivered to the account designated by the Partnership.  If the Partnership, or its transfer agent (if applicable), shall default on its obligation to deliver the Units on any Settlement Date, the Partnership shall (A) indemnify and hold the Manager harmless against any loss, claim or damage arising from or as a result of such default by the Partnership; and (B) pay the Manager any commission to which it would otherwise be entitled absent such default.  The Authorized Partnership Representatives shall be the contact persons for the Partnership for all matters related to the settlement of the transfer of the Units through DWAC for purposes of this Section 3(a)(vi).

17

(vii)     At each Time of Sale, Settlement Date and Representation Date (as defined in Section 4(p)), the Partnership shall be deemed to have affirmed each representation and warranty contained in this Agreement as if such representation and warranty were made as of such date, but modified to incorporate the disclosures contained or incorporated by reference in the Registration Statement and the Prospectus, in each case as amended or supplemented as of such date.  Any obligation of the Manager to use its reasonable efforts to sell the Units on behalf of the Partnership shall be subject to the continuing accuracy of the representations and warranties of the Partnership herein (as modified in the manner described above), to the performance by the Partnership of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 6 of this Agreement.

(b)             If the Partnership wishes to issue and sell the Units other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify the Manager of the proposed terms of such Placement.  If the Manager, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Partnership, wishes to accept amended terms, the Manager and the Partnership will enter into a Terms Agreement setting forth the terms of such Placement.  In the event of a conflict between the terms of this Agreement and the terms of any Terms Agreement, the terms of such Terms Agreement will control.

(c)             (i)            Under no circumstances shall the Partnership cause or request the offer or sale of any Units if, after giving effect to the sale of such Units, the aggregate gross sales proceeds or the aggregate number of the Units sold pursuant to this Agreement, the Alternative Agreement or any Placement would exceed the lesser of (A) the Maximum Amount, (B) the amount available for offer and sale under the currently effective Registration Statement and (C) the amount authorized from time to time to be issued and sold under this Agreement or the Alternative Agreement by G&P LLC’s board of directors, or a duly authorized committee thereof, and notified to the Manager in writing.  Under no circumstances shall the Partnership cause or request the offer or sale of any Units at a price lower than the minimum price authorized from time to time by the G&P LLC’s board of directors or a duly authorized committee thereof.

(ii)           If either party has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Units, it shall promptly notify the other party and sales of the Units under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(d)             Each sale of the Units to or through the Manager shall be made in accordance with the terms of this Agreement or, if applicable, a Terms Agreement.

(e)             Subject to such further limitations on offers and sales of Units or delivery of instructions to offer and sell Units as are set forth herein and as may be mutually agreed upon by the Partnership and the Manager, offers and sales of Units pursuant to this Agreement shall not be requested by the Partnership and need not be made by the Manager at any time when or during any period in which the Partnership is or is deemed to be in possession of material non-public information.

18

(f)              The Partnership acknowledges and agrees that (i) there can be no assurance that the Manager will be successful in selling the Units, (ii) the Manager will incur no liability or obligation to the Partnership or any other person or entity if it does not sell Units for any reason other than a failure by the Manager to use its reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Units in accordance with the terms of this Agreement, and (iii) the Manager shall be under no obligation to purchase Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed in writing by the Manager and the Partnership.

SECTION 4.  Covenants of the Partnership.  The Partnership agrees with the Manager:

(a)             To notify the Manager promptly of the time on or after the date of this Agreement when the Registration Statement or any amendment to the Registration Statement has been filed or become effective or when the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus or any supplement to any of the foregoing has been filed; to prepare and file with the Commission, promptly upon the Manager’s request, any amendments or supplements to the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus that, in the Manager’s reasonable opinion, may be necessary or advisable in connection with the offering of the Units by the Manager; and to cause the Basic Prospectus, the Prospectus Supplement and the Prospectus and each amendment or supplement to the Basic Prospectus, the Prospectus Supplement or the Prospectus to be filed with the Commission as required pursuant to the applicable paragraph of Rule 424(b) of the Act (without reliance on Rule 424(b)(8)) or, in the case of any Incorporated Document, to be filed with the Commission as required pursuant to the Exchange Act, within the time period prescribed; to cause each Permitted Free Writing Prospectus to be filed with the Commission as required by Rule 433 of the Act (to the extent such filing is required by such rule) and to retain copies of each Permitted Free Writing Prospectus that is not required to be filed with the Commission in accordance with Rule 433 of the Act.

(b)             To promptly advise the Manager, confirming such advice in writing, of any suspension of the Manager’s obligations under Rule 15c2-8 under the Exchange Act or any request by the Commission for amendments or supplements to the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus (in each case including, without limitation, any Incorporated Document) or for additional information with respect thereto, or of notice of examination, institution of proceedings for or the entry of a stop order suspending the effectiveness of the Registration Statement and, if the Commission should enter a stop order suspending the effectiveness of the Registration Statement, to use its best efforts to obtain the lifting or removal of such order as soon as possible; to promptly advise the Manager of any proposal to amend or supplement the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus (other than any amendment or supplement to be effected by the Partnership’s filing of a report, document or proxy or information statement pursuant to Sections 13, 14 or 15(d) of the Exchange Act, which shall be subject to the provisions of clause (2) of Section 4(d) below), and to provide the Manager and its counsel copies of any such documents for review and comment a reasonable amount of time prior to any proposed filing and not to file or use any such amendment or supplement (other than any prospectus supplement relating to the offering of other

19

securities (including, without limitation, the Common Units)) to which the Manager shall have objected in writing.

(c)             To make available to the Manager, as soon as practicable after this Agreement becomes effective, and thereafter from time to time to furnish to the Manager, as many copies of the Prospectus and each Permitted Free Writing Prospectus (or of the Prospectus or any Permitted Free Writing Prospectus as amended or supplemented if the Partnership shall have made any amendments or supplements thereto after the effective date of the Registration Statement) as the Manager may request for the purposes contemplated by the Act; in case the Manager is required to deliver (whether physically, deemed to be delivered pursuant to Rule 153 or through compliance with Rule 172 under the Act or any similar rule), in connection with the sale of the Units, a prospectus after the nine-month period referred to in Section 10(a)(3) of the Act, or after the time a post-effective amendment to the Registration Statement is required pursuant to Item 512(a) of Regulation S-K under the Act, the Partnership will prepare, at its expense, such amendment or amendments to the Registration Statement and the Prospectus as may be necessary to permit compliance with the requirements of Section 10(a)(3) of the Act or Item 512(a) of Regulation S-K under the Act, as the case may be.

(d)             (1) Subject to clause (2) of this Section 4(d), to file promptly all reports and documents and any preliminary or definitive proxy or information statement required to be filed by the Partnership with the Commission in order to comply with the Exchange Act for so long as a prospectus is required by the Act to be delivered (whether physically, deemed to be delivered pursuant to Rule 153 or through compliance with Rule 172 under the Act or any similar rule) in connection with any sale of Units; and (2) to provide the Manager, for its review, with a copy of any reports and statements and other documents to be filed by the Partnership pursuant to Section 13, 14 or 15(d) of the Exchange Act a reasonable amount of time prior to any proposed filing, and to promptly notify the Manager of such filing.

(e)             If the Partnership receives from the Commission a notice pursuant to Rule 401(g)(1) under the Act or otherwise ceases to be eligible to use a Form S-3 registration statement, the Partnership will (i) promptly notify the Manager; (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Units, in a form satisfactory to the Manager; (iii) use its best efforts to cause such registration statement or post-effective amendment to be declared effective as soon as practicable (if such filing is not otherwise effective immediately pursuant to Rule 462 under the Act); and (iv) promptly notify the Manager of such effectiveness.  The Partnership will take all other action necessary or appropriate to permit the public offering and sale of the Units to continue as contemplated in the Registration Statement that was the subject of the notice under Rule 401(g)(2) under the Act or for which the Partnership has otherwise become ineligible.  References herein to the Registration Statement relating to the Units shall include such new registration statement or post-effective amendment, as the case may be.

(f)              If immediately prior to the third anniversary (the “Renewal Deadline”) of the initial effective date of the Registration Statement, any of the Units remain unsold by the Manager, the Partnership will, prior to the Renewal Deadline file, if it has not already done so and is eligible to do so, a new shelf registration statement relating to the Units, in a form reasonably satisfactory to the Manager,  and use its commercially reasonable efforts to

20

(d)           If the indemnification provided for in this Section 7 is unavailable to an indemnified party under subsections (a) and (b) of this Section 7 or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership, on the one hand, and the Manager, 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, on the one hand, and of the Manager, on the other, in connection with the statements or omissions which resulted in such losses, damages, expenses, liabilities or claims, as well as any other relevant equitable considerations.  The relative benefits received by the Partnership, on the one hand, and the Manager, on the other, shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Partnership, and the total underwriting discounts and commissions received by the Manager, bear to the aggregate public offering price of the Units.  The relative fault of the Partnership, on the one hand, and of the Manager, on the other, shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Partnership or by the Manager and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(e)           The Partnership and the Manager agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in subsection (d) above.  Notwithstanding the provisions of this Section 7, the Manager shall not be required to contribute any amount in excess of underwriting discounts and commissions received by it under this Agreement.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f)            The Partnership and the Manager agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Partnership, against any of the Partnership’s officers or directors in connection with the issuance and sale of the Units, or in connection with the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

SECTION 8.  Representations and Agreements to Survive Delivery.  The indemnity and contribution agreements contained in Section 7 and the covenants, warranties and representations of the Partnership contained in this Agreement or in certificates delivered pursuant hereto shall remain in full force and effect regardless of any investigation made by or on behalf of the Manager or any of its affiliates or its or their employees, members, partners, directors, officers, and agents or any person (including each employee, member, partner, director, officer and agent

31

of such person) who controls the Manager within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, or by or on behalf of the Partnership, its directors or officers or any person who controls the Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the issuance and delivery of the Units.

SECTION 9.  Termination.

(a)             The Partnership shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Units in its sole discretion at any time.  Any such termination shall be without liability of any party to any other party except that (i) if any of the Units have been sold through the Manager for the Partnership, then Section 4(aa) shall remain in full force and effect; (ii) with respect to any pending sale, through the Manager for the Partnership, the obligations of the Partnership, including in respect of compensation of the Manager, shall remain in full force and effect notwithstanding the termination; and (iii) the provisions of Sections 5, 7, 8, 10, 11, 12, 16, 17, 18, 19 and 20 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b)           The Manager shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Units in its sole discretion at any time.  Any such termination shall be without liability of any party to any other party except that the provisions of Sections 5, 7, 8, 10, 11, 12, 16, 17, 18, 19 and 20 of this Agreement shall remain in full force and effect notwithstanding such termination.

(c)           This Agreement shall remain in full force and effect unless terminated pursuant to Sections 9(a) or (b) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that the provisions of Sections 5, 7, 8, 10, 11, 12, 16, 17, 18, 19 and 20 of this Agreement shall remain in full force and effect notwithstanding such termination.

(d)           Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Manager or the Partnership, as the case may be.  If such termination shall occur prior to the Settlement Date for any sale of the Units, such sale shall settle in accordance with the provisions of Section 3(a)(vi) of this Agreement.

SECTION 13.  Press Releases and Disclosure.  The Partnership may issue a press release in compliance with Rule 134 under the Act describing the material terms of the transactions contemplated hereby as soon as practicable following the date hereof, and may file with the Commission a Current Report on Form 8-K describing the material terms of the transaction contemplated hereby, and the Partnership shall consult with the Manager prior to making such disclosures, and the parties shall use all reasonable efforts, acting in good faith, to agree upon a text for such disclosures that is reasonably satisfactory to all parties.  No party hereto shall issue thereafter any Current Report on Form 8-K or press release or like public statement (including, without limitation, any disclosure required in reports filed with the Commission pursuant to the Exchange Act) related to this Agreement or any of the transactions contemplated hereby without the prior written consent of the other party, except as may be necessary or appropriate in the opinion of the party seeking to make disclosure to comply with the requirements of applicable law or stock exchange rules.  If any such press release or like public statement is so required, the

33

party making such disclosure shall consult with the other party prior to making such disclosure, and the parties shall use all reasonable efforts, acting in good faith, to agree upon a text for such disclosure that is reasonably satisfactory to all parties.

SECTION 14.  Adjustments for Stock Splits.  The parties acknowledge and agree that all Common Unit-related numbers contained in this Agreement shall be adjusted to take into account any stock split effected with respect to the Units.

SECTION 15.  Entire Agreement.  This Agreement constitutes the entire agreement and supersedes all other prior and contemporaneous agreements and undertakings, both written and oral, among the parties hereto with regard to the subject matter hereof.

SECTION 16.  Counterparts.  This Agreement may be signed by the parties in one or more counterparts which together shall constitute one and the same agreement among the parties.

SECTION 17.  Law; Construction.  This Agreement and any claim, counterclaim or dispute of any kind or nature whatsoever arising out of or in any way relating to this Agreement (“Claim”), directly or indirectly, shall be governed by, and construed in accordance with, the internal laws of the State of New York.

SECTION 18.  Headings.  The Section headings in this Agreement have been inserted as a matter of convenience of reference and are not a part of this Agreement.

SECTION 19.  Submission to Jurisdiction.  Except as set forth below, no Claim may be commenced, prosecuted or continued in any court other than the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, which courts shall have jurisdiction over the adjudication of such matters, and the Partnership consents to the jurisdiction of such courts and personal service with respect thereto.  The Partnership hereby consents to personal jurisdiction, service and venue in any court in which any Claim arising out of or in any way relating to this Agreement is brought by any third party against the Manager or any indemnified party.  Each of the Manager and the Partnership (on its behalf and, to the extent permitted by applicable law, on behalf of its stockholders and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement.  The Partnership agrees that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the Partnership and may be enforced in any other courts to the jurisdiction of which the Partnership is or may be subject, by suit upon such judgment.

SECTION 20.  Successors and Assigns.  This Agreement shall be binding upon the Manager and the Partnership and their successors and assigns and any successor or assign of any substantial portion of the Partnership’s and the Manager’s respective businesses and/or assets.  Neither party may assign or otherwise transfer this Agreement without the prior written consent of the other party.

SECTION 22.  Miscellaneous.  The Manager, an indirect, wholly-owned subsidiary of UBS AG, is not a bank and is separate from any affiliated bank, including any U.S. branch or agency of UBS AG.  Because the Manager is a separately organized entity, it is solely responsible for its own contractual obligations and commitments, including obligations with respect to sales and purchases of securities.  Securities sold, offered or recommended by the Manager are not deposits, are not insured by the Federal Deposit Insurance Corporation, are not guaranteed by a branch or agency, and are not otherwise an obligation or responsibility of a branch or agency.

UBS Securities LLC
c/o UBS Securities LLC

Ladies and Gentlemen:

This opinion is provided to you pursuant to Section 6(c) of the Equity Distribution Agreement, dated May 30, 2012 (the “Agreement”), by and between Eagle Rock Energy Partners, L.P. (the “Partnership”) and UBS Securities LLC, as sales agent (the “Manager”), pursuant to which the Partnership may offer and sell, through the Manager, common units representing limited partner interests in the Partnership (“Common Units”), having an aggregate gross sales price of up to $100,000,000 (the “Units”), pursuant to the terms set forth in Section 3 of the Agreement.  Any capitalized term used in this opinion and not defined herein shall have the meaning assigned to such term in the Agreement; and any references in this opinion to information that is “contained,” “included” or “stated” (or other references of like import) in the Registration Statement or the Prospectus mean and include all information and documents that are incorporated or deemed to be incorporated by reference therein.

We have acted as counsel to the Partnership in connection with the offer and sale by the Partnership of the Units.  In connection with the opinions expressed below, we have examined the following:

(a)                                 a copy of the Certificate of Limited Partnership of the Partnership as filed with the Secretary of State of the State of Delaware on May 25, 2006, certified as of a recent date, and a copy, certified by the Secretary of Eagle Rock Energy G&P, LLC (“G&P LLC”) to be a true copy, of the Second Amended and Restated Agreement of Limited Partnership of the Partnership dated May 24, 2010, as amended as of the date hereof (as amended, the “Partnership Agreement”);

(b)                                 a copy of the Certificate of Limited Partnership of Eagle Rock Energy GP, L.P. (the “General Partner”) as filed with the Secretary of State of the State of Delaware on May 25, 2006, certified as of a recent date, and a copy, certified as of a recent date by the Secretary of G&P LLC to be a true copy, of the Agreement of Limited Partnership of the General Partner dated May 25, 2006;

(c)                                  a copy of the Certificate of Formation of G&P LLC as filed with the Secretary of State of the State of Delaware on May 25, 2006, certified as of a recent date, a copy, certified as of a recent date by the Secretary of G&P LLC to be a true copy, of the Second Amended and Restated Limited Liability Company Agreement of G&P LLC dated October 27, 2006, and a

(d)                                 the Constituent Documents of the Partnership’s other Subsidiaries, certified as of a recent date, as applicable;

(e)                                  copies of (i) an excerpt from the minutes of the Board of Directors (the “Board”) of G&P LLC meeting held on October 27, 2009, and (ii) an excerpt from the minutes of the Board meeting held on April 24, 2012, each certified as of a recent date by the Secretary of G&P LLC;

(f)                                   a copy of the Registration Statement;

(g)                                  the Prospectus;

(h)                                 the Agreement;

(i)                                     reports, dated as of recent dates, prepared by CT Lien Solutions purporting to describe all financing statements on file as of the dates thereof in the office of the Secretary of State of the State of Delaware, naming the Partnership or certain of its subsidiaries as debtors;

(j)                                    evidence satisfactory to us of the effectiveness of the Registration Statement; and

(k)                                 such other documents as we have deemed appropriate for purposes of the opinions expressed below.

Based on the foregoing, and subject to the qualifications and limitations set forth below, we are of the opinion that:

1.                                      Each of the Partnership, the General Partner, G&P LLC and the Partnership’s other Significant Subsidiaries (as defined in Rule 405 of the Rules and Regulations) identified on Schedule I hereto validly exists and is in good standing under the laws of its jurisdiction of organization, is duly registered or qualified to do business and is in good standing in each jurisdiction set forth opposite its name on Schedule I hereto, and each has all power and authority necessary to own or lease its properties and to conduct its businesses in which it is engaged as described in the Registration Statement, the Prospectus and the Permitted Free Writing Prospectuses attached hereto as Annex A.

2.                                      The Partnership has full limited partnership right, power and authority to execute and deliver this Agreement and to perform its obligations thereunder

3.                                      The General Partner is the sole general partner of the Partnership, with all necessary limited partnership authority to act as general partner of the Partnership.

4.                                      G&P LLC is the sole general partner of the General Partner, with all necessary limited liability company authority to act as general partner of the General Partner.

5.                                     The Agreement has been duly authorized, executed and delivered by the Partnership.

A-2

6.                                      Upon due action by the Authorized Partnership Representatives pursuant to Section 3(a)(i) of the Agreement, the Units will have been duly authorized and, when paid for in accordance with the terms of this Agreement, will be duly authorized for sale and issuance, and when issued and delivered by the Partnership against payment of the consideration set forth herein, will be validly issued, fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by matters described in Sections 17-303, 17-607 and 17-804 of the DRULPA).

7.                                      The Common Units, including the Units, conforms in all material respects to the description thereof, if any, contained in the Registration Statement, the Prospectus and the Permitted Free Writing Prospectuses attached hereto as Annex A.

8.                                      Each of the Registration Statement and the Prospectus (except as to the financial statements and schedules, and other financial data derived therefrom, and the oil and natural gas reserve estimates contained or incorporated by reference in the Registration Statement and the Prospectus, as to which we express no opinion) appears on its face to comply as to form in all material respects with the requirements of the Act (including, in the case of the Prospectus, Section 10(a) of the Act); and the Registration Statement meets, and the offering and sale of the Units as contemplated by the Agreement complies with, the requirements of Rule 415 under the Act (including, without limitation, Rule 415(a)(5)).

9.                                      The Registration Statement has become effective under the Act and, to our knowledge, no stop order proceedings with respect thereto are pending or threatened under the Act, and any required filing of the Prospectus and any supplement thereto pursuant to Rule 424 or Rule 430B under the Act has been made in the manner and within the time period required by such Rule 424 (without giving effect to Rule 424(b)(8)) and in compliance with Rule 430B under the Act, and any required filing of a Permitted Free Writing Prospectus pursuant to Rule 433 under the Act has been made in the manner, within the time period and otherwise in compliance with such Rule 433.

10.                               No approval, authorization, consent or order under any federal law, the laws of the State of New York or under the DRULPA or approval, authorization, consent of or filing with any New York or Delaware governmental or regulatory commission, board, body, authority or agency is required in connection with the issuance and sale of the Units by the Partnership or the transactions contemplated by the Agreement other than registration of the issuance of the Units under the Act except (A) such as may be required under the blue sky laws of any jurisdiction or the by-laws and rules of FINRA in connection with the offer and sale of the Units in the manner contemplated herein and in the Prospectus (as to which we express no opinion) and (B) such other that have been obtained or taken and are in full force and effect.

11.                               The execution, delivery and performance by the Partnership of the Agreement, the issuance of the Units and the consummation of the transactions contemplated by the Agreement does not and will not (i) assuming application of the proceeds from the sale of the Units in the manner set forth in the Prospectus, violate, or constitute a breach or

A-3

default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which any of the Partnership or the Subsidiaries is a party or by which any of them or any of their respective properties may be bound, that is filed or incorporated by reference as an exhibit to (A) the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2011 and (B) each current or periodic report filed by the Partnership with the Commission from the date of filing of such Annual Report on Form 10-K to the date hereof; (ii) result in any violation of the provisions of the Constituent Documents of the Partnership or (iii) result in the violation of the Delaware General Corporations Law, the Delaware LLC Act, the DRULPA, the laws of the State of New York or Texas or federal law or any Applicable Order; provided, however, that the opinion expressed in clause (iii) herein shall not include state or federal securities or “Blue Sky” laws or other antifraud statutes, rules or regulations; provided further, however, that “Applicable Order” means judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory authority identified in a certificate of the Partnership and provided to such counsel.

12.                               The Partnership Agreement has been duly authorized, executed and delivered by the Partnership and the General Partner and is a valid and legally binding agreement of the Partnership and the General Partner, enforceable against the Partnership and the General Partner in accordance with its terms; provided that the enforceability thereof is subject to (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting the rights and remedies of creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (ii) public policy, applicable law relating to fiduciary duties and indemnification and contribution and an implied covenant of good faith and fair dealing.

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

14.                               The statements in the Registration Statement and the Prospectus under the headings “Material U.S. Federal Income Tax Consequences,” insofar as such statements constitute summaries of documents or legal proceedings or refer to matters of law or legal conclusions, constitute accurate summaries of the matters described therein in all material respects.

15.                               No person has the right, pursuant to the terms of any contract, agreement or other instrument described in or filed as an exhibit to the Registration Statement or any Incorporated Document, to cause the Partnership to register under the Act any Common Units or other equity interests in the Partnership or to include any such interest in the Registration Statement or the offering of the Units contemplated thereby, other than as have been effectively complied with, satisfied or waived.

16.                               The opinion of Vinson & Elkins L.L.P. that is filed as Exhibit 8.1 to the Registration Statement is confirmed, and the Manager may rely upon such opinion as if it were addressed to the Manager.

A-4

In rendering the opinions expressed herein, we have

(A)                               relied, with respect to matters of fact, upon the representations of the Partnership contained in the Agreement, certificates of officers and employees of G&P LLC, to the extent we deemed appropriate, and information obtained from public officials,

(B)                               assumed that all documents submitted to us as originals are authentic, that all copies submitted to us conform to the originals thereof, and that the signatures on all documents examined by us are genuine,

(C)                               assumed that each certificate from governmental officials reviewed by us is accurate, complete and authentic, and all official public records are accurate and complete,

(D)                               with respect to the opinions expressed in paragraph (1) concerning “good standing,” we have relied solely on a review of “good standing” certificates dated as of a date not less than two weeks prior to the date hereof,

(E)                                with respect to the opinions expressed in paragraph (6), relied on reports, dated as of recent dates, prepared by Corporation Service Company, purporting to describe all financing statements on file as of the dates thereof in the office of the Secretary of State of the State of Delaware, naming the Partnership or certain of its subsidiaries as debtors, and

(F)                             not expressed an opinion with respect to (i) any permits to own or operate any real or personal property or (ii) state or local taxes or tax statutes to which any of the limited partners of the Partnership, any of the limited partners of the General Partner, G&P LLC or any of the Significant Subsidiaries may be subject.

In addition, we have participated in conferences with officers of G&P LLC and other representatives of the Partnership, representatives of the independent public accountants of the Partnership and representatives of the Manager at which the contents of the Registration Statement, the Basic Prospectus, the Prospectus and the Permitted Free Writing Prospectuses (if any) were discussed and, although we are not passing upon and do not assume responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Basic Prospectus, the Prospectus or any Permitted Free Writing Prospectus (except as and to the extent stated in subparagraphs 7, 8 and 14 above), on the basis of the foregoing, nothing has come to our attention that causes us to believe that (i) the Registration Statement, at each time it is considered to have become effective as to the Manager pursuant to Section 11(d) of the Act and Rule 430B promulgated thereunder, contained an 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 or (ii) the Prospectus, as of the date hereof [Note: initial opinion to be dated as of the date of program commencement; subsequent opinions to be dated as of the applicable Representation Date], together with the Permitted Free Writing Prospectuses (if any) identified in Annex A, includes an untrue statement of a material fact or omits 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 (it being understood that we make no statement herein with respect to (i) the financial statements and schedules, and other financial data derived therefrom, (ii) the representations and warranties and other statement of fact included in exhibits

A-5

Ladies and Gentlemen:

This opinion is provided to you pursuant to Section 6(d) of the Equity Distribution Agreement, dated May 30, 2012 (the “Agreement”), by and between Eagle Rock Energy Partners, L.P. (the “Partnership”) and UBS Securities LLC, as sales agent (the “Manager”), pursuant to which the Partnership may offer and sell, through the Manager, common units representing limited partner interests in the Partnership (“Common Units”), having an aggregate gross sales price of up to $100,000,000 (the “Units”), pursuant to the terms set forth in Section 3 of the Agreement.  Any capitalized term used in this opinion and not defined herein shall have the meaning assigned to such term in the Agreement; and any references in this opinion to information that is “contained,” “included” or “stated” (or other references of like import) in the Registration Statement or the Prospectus mean and include all documents and information that is incorporated or is deemed to be incorporated by reference therein.

I am Senior Vice President, General Counsel, Chief Compliance Officer and Secretary of Eagle Rock Energy G&P, LLC, a Delaware limited liability company (“G&P LLC”) and the sole general partner of Eagle Rock Energy GP, L.P., a Delaware limited partnership (the “General Partner”) and the sole general partner of the Partnership, and have acted as counsel to the Partnership in connection with the offer and sale by the Partnership of the Units.  In connection with the opinions expressed below, I have examined the following:

(a)                                 a copy of the Certificate of Limited Partnership of the Partnership as filed with the Secretary of State of the State of Delaware on May 25, 2006, certified as of a recent date, and a copy of the Second Amended and Restated Agreement of Limited Partnership of the Partnership dated May 24, 2010, as amended;

(b)                                 a copy of the Certificate of Limited Partnership of the General Partner as filed with the Secretary of State of the State of Delaware on May 25, 2006, certified as of a recent date, and a copy of the Agreement of Limited Partnership of the General Partner dated May 25, 2006;

(c)                                  a copy of the Certificate of Formation of G&P LLC as filed with the Secretary of State of the State of Delaware on May 25, 2006, certified as of a recent date, and a copy of the Third Amended and Restated Limited Liability Company Agreement of the General Partner dated July 30, 2010;

(i)                                     reports, dated as of recent dates, prepared by CT Lien Solutions purporting to describe all financing statements on file as of the dates thereof in the office of the Secretary of State of the State of Delaware, naming the Partnership or certain of its subsidiaries as debtors;

(j)                                    evidence satisfactory to me of the effectiveness of the Registration Statement; and

(k)                                 such other documents as I have deemed appropriate for purposes of the opinions expressed below.

Based on the foregoing, and subject to the qualifications and limitations set forth below, I am of the opinion that:

(i)                                     To the best of my knowledge, except as described in the Registration Statement and the Prospectus, there are no legal, governmental or regulatory investigations, actions, suits or proceedings pending to which any of the Partnership or its Subsidiaries is or may be a party or to which any property of any of the Partnership or its Subsidiaries is or may be the subject which, individually or in the aggregate, if determined adversely to such Partnership or its Subsidiaries, would reasonably be expected to have a Material Adverse Effect; and no such investigations, actions, suits or proceedings are threatened or, to the best of my knowledge, contemplated by any governmental or regulatory authority or threatened by others.

(ii)                                  The descriptions in the Registration Statement and the Prospectus of statutes, legal, governmental and regulatory proceedings and contracts and other documents (other than the Units) are accurate in all material respects; and, to the best of my knowledge, (i) there are no current or pending legal, governmental or regulatory actions, suits or proceedings that are required under the Act to be described in the Registration Statement and the Prospectus and that are not so described in the Registration Statement and the Prospectus and (ii) there are no statutes, regulations or contracts and other documents that are required under the Act to be filed as exhibits to the Registration Statement or described in the Registration Statement and the Prospectus and that have not been so filed as exhibits to the Registration Statement or described in the Registration Statement and the Prospectus.

(iii)                               Except as described in the Registration Statement and the Prospectus, the Partnership owns (i) 100% of the capital stock of Eagle Rock Energy Finance Corp., a Delaware corporation, Eagle Rock Energy G&P Holding, Inc., a Delaware corporation, Eagle Rock Energy Acquisition

II, Inc., a Delaware corporation, (ii) 100% of the limited liability company interests of each Eagle Rock Marketing, LLC, a Delaware limited liability company, Eagle Rock Pipeline GP, LLC, a Delaware limited liability company, Eagle Rock Gas Services, LLC, a Delaware limited liability company, EROC Production, LLC, a Delaware limited liability company, and Eagle Rock Mid-Continent Holding, LLC, a Delaware limited liability company, (iii) 99.5% of the limited liability company interests of G&P LLC, (iv) a 99.999% limited partner interest of EROC Midstream Energy, L.P., a Delaware limited partnership, (v) a 99% limited partner interest of each of Eagle Rock Pipeline, L.P., a Delaware limited partnership, and Eagle Rock Upstream Development II, L.P., a Texas limited partnership, and (vi) a 95% limited partner interests of each of Eagle Rock Acquisition Partnership, L.P., a Delaware limited partnership, and Eagle Rock Acquisition Partnership, II L.P., a Delaware limited partnership. All such capital stock, limited liability company interests or limited partnership interest, as the case may be, are owned free and clear of all liens, encumbrances (except restrictions on transferability as described in the Registration Statement and the Prospectus), security interests, equities, charges and other claims (other than those arising under the Credit Agreement) (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the Partnership is on file as of a recent date in the office of the Secretary of State of the State of Delaware or (ii) otherwise known to me, without independent investigation, other than those created by or arising under the Delaware General Corporation Law (the “DGCL”) or the Delaware LLC Act.

I am licensed to practice law in the State of Texas.  In rendering these opinions (i) I have relied upon certificates and representations of other officers of G&P LLC and of the subsidiaries and of other individuals whom I consider reliable, as well as the representations and warranties contained in the Agreement, with respect to the accuracy of certain factual matters contained therein, and (ii) I have assumed that all documents submitted to me as originals are authentic, that all copies submitted to me conform to the originals thereof, and that the signatures on all documents examined by me are genuine. The foregoing opinions are limited in all respects to the DGCL, the DRULPA, the Delaware LLC Act, the laws of the State of Texas and applicable federal law, in each case as in effect on the date hereof.  This opinion is provided in my capacity as Senior Vice President, General Counsel and Corporate Secretary of G&P LLC and not in my individual capacity as an attorney.  The opinions expressed herein are for your benefit and may be relied upon only by you.  This opinion speaks as of the date hereof, and I disclaim any obligation to update this opinion.
