(g) Issuer Free Writing Prospectuses Conform to the Requirements of the Securities Act.

(iii) they have examined the Registration Statement, the Prospectus and the Pricing Disclosure Package, and, in their opinion (A) (1) the Registration Statement, as of the Effective Date, (2) the Prospectus, as of its date and on the applicable Delivery Date, or (3) the Pricing Disclosure Package, as of the Applicable Time, did not contain any untrue statement of a material fact and did not omit to state a material fact required to be stated therein or necessary to make the statements therein (except in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading, and (B) since the Effective Date, no event has occurred that should have been set forth in a supplement or amendment to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus that has not been so set forth.

(j) Except as described in the most recent Preliminary Prospectus and the Prospectus, (i) none of the Partnership Entities shall have sustained since the date of the latest audited financial statements included in the most recent Preliminary Prospectus and the Prospectus any loss or interference with its business from fire, flood, explosion or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree; (ii) nor shall there have been a change in the partners’ capital, members’ interest, or long-term debt of any of the Partnership Entities or change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), results of operations, properties, management, business or prospects of the Partnership Entities taken as a whole, the effect of which, in any such case described in clause (i) or (ii), in the judgment of the Representatives is so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Units being delivered on the applicable Delivery Date on the terms and in the manner contemplated in the Prospectus.

(k) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the NYSE, the NYSE Amex Equities or the Nasdaq Global Market or in the over-the-counter market, or trading in any securities of the Partnership on

any exchange or in the over-the-counter market, shall have been suspended or materially limited or the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by federal or state authorities, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States or (iv) there shall have occurred such a material adverse change in general economic, political or financial conditions, including, without limitation, as a result of terrorist activities after the date hereof (or the effect of international conditions on the financial markets in the United States shall be such) as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the public offering or delivery of the Units being delivered on the applicable Delivery Date on the terms and in the manner contemplated in the Prospectus.

(l) The NYSE shall have approved the Units for listing.

(m) The Lock-Up Agreements between the Representatives and each person or entity set forth on Schedule 5, delivered to the Representatives on or before the date of this Agreement, shall be in full force and effect on each Delivery Date.

All such opinions, certificates, letters and documents mentioned above or elsewhere in this Agreement shall be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to the Representatives and to counsel for the Underwriters.

8. Indemnification and Contribution.

(a) Each of the Partnership Parties, jointly and severally, shall indemnify and hold harmless each Underwriter, its directors, officers, employees and agents, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of the Units), to which that Underwriter, director, officer, employee, agent or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto or (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) used or referred to by any Underwriter or (ii) (A) the omission or alleged omission to state in any the Registration Statement or in any amendment or supplement thereto any material fact required to be stated therein or necessary to make the statements therein not misleading or (B) the omission or alleged omission to state in any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, and shall reimburse each Underwriter and each such director, officer, employee, agent or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee, agent or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Partnership Parties shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information, in reliance upon and in conformity with written information concerning an Underwriter furnished to the Partnership Parties by or on behalf of an Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 8(e). The foregoing indemnity agreement is in addition to any liability that the Partnership Parties may otherwise have to the Underwriters or to any director, officer, employee, agent or controlling person of the Underwriters.

(b) Each Underwriter severally shall indemnify and hold harmless each of the Partnership Parties, their respective directors, managers, officers and employees, and each person, if any, who controls any of the Partnership Parties within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Partnership Parties or any such director, manager, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or (ii) (A) the omission or alleged omission to state in the Registration Statement or in any amendment or supplement thereto any material fact required to be stated therein or necessary to make the statements therein not misleading or (B) the omission or alleged omission to state in any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning an Underwriter furnished to the Partnership by or on behalf of an Underwriter specifically for inclusion

therein, which information is limited to the information set forth in Section 8(e). The foregoing indemnity agreement is in addition to any liability that the Underwriters may otherwise have to the Partnership Parties or any such director, manager, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced by such failure; provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees, agents and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 8 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers, employees, agents and controlling persons shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees, agents or controlling persons, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Partnership, on

the one hand, and the Underwriters, on the other, from the offering of the Units or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership Parties, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Partnership, on the one hand, and the Underwriters, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Units purchased under this Agreement (before deducting expenses) received by the Partnership, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Units purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Partnership Parties and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), an Underwriter shall not be required to contribute any amount in excess of the amount by which the gross proceeds from the sale of the Units underwritten by it exceeds the amount of any damages that the Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(e) The Underwriters confirm and the Partnership Parties acknowledge that the statements regarding the delivery of the Units by the Underwriter set forth on the cover page of the Prospectus and the concession figure in the fifth paragraph and the statements in the thirteen, fourteenth and fifteenth paragraphs dealing with stabilization or related activities appearing under the caption “Underwriting (Conflicts of Interest)” in the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning the Underwriters furnished in writing to the Partnership by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, Registration Statement, the Prospectus any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

9. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Partnership prior to delivery of and payment for the Units if, prior to that time, any of the events described in Sections 7(j) or 7(k) shall have occurred or if the Underwriters shall decline to purchase the Units for any reason permitted under this Agreement.

10. Reimbursement of Underwriters’ Expenses. If the Partnership shall fail to tender the Units for delivery to the Underwriters by reason of any failure, refusal or inability on the part of any of the Partnership Parties to perform any agreement on its part to be performed, or because any other condition of the Underwriters’ obligations hereunder required to be fulfilled by the Partnership Parties is not fulfilled for any reason, the Partnership Parties will, jointly and severally, reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Units, and upon demand the Partnership Parties shall pay the full amount thereof to the Underwriters. If this Agreement is

terminated by reason of the default of the Underwriters or pursuant to Section 7(k), the Partnership Parties shall not be obligated to reimburse the Underwriters on account of their expenses.

11. Research Analyst Independence. The Partnership Parties acknowledge that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Partnership and/or the offering that differ from the views of their respective investment banking divisions. The Partnership Parties hereby waive and release, to the fullest extent permitted by law, any claims that the Partnership Parties may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by its independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Partnership Parties by such Underwriters’ investment banking divisions. The Partnership Parties acknowledge that each Underwriter is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

12. No Fiduciary Duty. The Partnership Parties acknowledge and agree that in connection with this offering and sale of the Units or any other services the several Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Partnership Parties and any other person, on the one hand, and any Underwriter, on the other, exists; (ii) no Underwriter is acting as an advisor, expert or otherwise, to any of the Partnership Parties, including, without limitation, with respect to the determination of the public offering price of the Units, and such relationship between the Partnership Parties, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Partnership Parties shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their affiliates may have interests that differ from those of the Partnership Parties. Each of the Partnership Parties hereby waive any claims that any such entity may have against each Underwriter with respect to any breach of fiduciary duty in connection with this offering.

13. Default by One or More of the Underwriters. If, on any Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Units that the defaulting Underwriter agreed but failed to purchase on such Delivery Date in the respective proportions which the number of Initial Units set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of Initial Units set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Units on such Delivery Date if the total number of Units that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 9.09% of the total number of Units to be purchased on such Delivery Date, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the number of Units that it agreed to purchase on such Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Units to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the Units that the defaulting Underwriter or Underwriters agreed but failed to purchase on such

Delivery Date, this Agreement (or, with respect to any Option Units Delivery Date, the obligation of the Underwriters to purchase, and of the Partnership to sell, the Option Units) shall terminate without liability on the part of any non-defaulting Underwriter or any of the Partnership Parties, except that the Partnership Parties will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 10. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 13, purchases Units that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Partnership Parties, including expenses paid pursuant to Sections 6 and 10, for damages caused by its default. If other Underwriters are obligated or agree to purchase the Units of a defaulting or withdrawing Underwriter, either the Representatives or the Partnership may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

14. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 15, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

17. Definition of the Terms “Business Day” and “Subsidiary.” For purposes of this Agreement, (a) “business day” means each Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close and (b) “subsidiary” has the meaning set forth in Rule 405 of the Rules and Regulations.

18. Governing Law. THIS AGREEMENT AND ANY CLAIM, CONTROVERSY OR DISPUTE RELATING TO OR ARISING OUT OF THIS AGREEMENT SHALL BE GOVERNED AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

(a) The Partnership has been duly formed and is validly existing in good standing as a limited partnership under the Delaware LP Act with all necessary partnership power and authority to own or lease its properties and to conduct its business, in each case in all material respects as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus. The Partnership has been duly registered or qualified as a foreign limited partnership for the transaction of business under the laws of the jurisdictions set forth on a schedule to such opinion.

(b) The General Partner has been duly formed and is validly existing in good standing as a limited liability company under the Delaware LLC Act with all necessary limited liability company power and authority to own or lease its properties and to conduct its business, in each case in all material respects as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus. The General Partner is duly registered or qualified as a foreign limited liability company for the transaction of business under the laws of the jurisdictions set forth on a schedule to such opinion.

(c) The Units and the limited partner interests represented thereby have been duly authorized by the Partnership Agreement and are 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(a), 17-607 and 17-804 of the Delaware LP Act).

(d) The Partnership is the sole member of the General Partner; such membership interest has been duly authorized and validly issued in accordance with the General Partner LLC Agreement, and is fully paid (to the extent required under General Partner LLC Agreement) and nonassessable (except as such nonassessability may be affected by matters described in Sections 18-303(b), 18-607 and 18-804 of the Delaware LLC Act); and the Partnership owns its membership interest free and clear of all Liens (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the Partnership as a debtor is on file in the office of the Secretary of State of the State of Delaware or (ii) otherwise known to such counsel, without independent investigation, other than those created by or arising under the Delaware LLC Act.

(e) The General Partner is the sole general partner of the Partnership with a non-economic management interest in the Partnership; such interest has been duly authorized and validly issued in accordance with the Partnership Agreement; and the General Partner owns such interest free and clear of all Liens (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the General Partner as a debtor is on file in the office of the Secretary of State of the State of Delaware or (ii) otherwise known to such counsel, without independent investigation, other than those created by or arising under the Delaware LP Act or contained in the Partnership Agreement.

To such counsel’s knowledge and except as provided in the Partnership Agreement and the Registration Rights Agreement, dated May 17, 2012, by and among the Partnership and the investors named on Schedule A thereto, neither the filing of the Registration Statement or the offering or sale of the Units as contemplated by this Agreement gives rise to any rights for or relating to the registration of any Units or other securities of the Partnership.

Exhibit A-1

(g) Each of the Partnership Parties has the requisite partnership or limited liability company power and authority, as the case may be, to execute and deliver this Agreement and to perform its obligations hereunder. All corporate, partnership or limited liability company action, as the case may be, required to be taken by any of the Partnership Parties or any of their respective partners, unitholders or members for the execution and delivery of this Agreement and the consummation of the transactions contemplated by this Agreement have been validly taken.

(ii) The General Partner LLC Agreement is a valid and legally binding agreement of the Partnership, enforceable against the Partnership in accordance with its terms;

provided that, with respect to each agreement described above, the enforceability thereof may be limited by (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding at law or in equity), and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.

(j) None of the execution, delivery and performance of this Agreement by the Partnership Parties, the offering and sale of the Units or the consummation of the transactions contemplated hereby (A) constitutes or will constitute a violation of the Partnership Organizational Agreements or the other organizational documents of any of the Partnership Parties, (B) constitutes or will constitute a breach or violation of, or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under, any agreement listed on a schedule to such opinion; (C) results or will result in the creation or imposition of any Liens upon any property or assets of any of the Partnership Entities, under any agreement listed on a schedule to such opinion; or (D) results or will result in a violation of the Delaware LP Act or the Delaware LLC Act or any federal statute, which violations or Liens, in the case of clauses (B), (C) or (D), would reasonably be expected to have a Material Adverse Effect or would materially impair the ability of the Partnership Parties to perform their obligations under this Agreement.

(k) No permit, consent, approval, authorization, order, registration, filing or qualification (“consent”) under the Delaware LP Act or the Delaware LLC Act or federal law is required for the execution, delivery and performance of this Agreement by the Partnership Parties or the consummation of the transactions contemplated hereby by the Partnership Parties, except for (i) such consents required under the Securities Act and the Exchange Act or under state securities or “Blue Sky” laws (as to which such counsel need not express any opinion) and (ii) such consents that have been, or prior to the Initial Delivery Date will be, obtained.

Exhibit A-2

“Material Provisions of Our Partnership Agreement” insofar as they purport to constitute summaries of the Partnership Agreement, the Common Units, matters of the Delaware LP Act or legal conclusions, are accurate summaries in all material respects.

(n) The opinion of ▇▇▇▇▇▇ & ▇▇▇▇▇▇ L.L.P. that is filed as Exhibit [8.1] to a Current Report on Form 8-K of the Partnership dated November [ ], 2012 is confirmed and the Underwriters may rely upon such opinion as if it were addressed to them.

(o) The Registration Statement became effective under the Securities Act on April 16, 2010. To the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Prospectus pursuant to Rule 424(b) has been made in the manner and within the time period required by such Rule.

(p) The Registration Statement, on the Effective Date and on the applicable Delivery Date, and the Prospectus, when filed with the Commission pursuant to Rule 424(b) and on the applicable Delivery Date, appeared, on their face, appropriately responsive, in all material respects, to the requirements of the Securities Act and the Rules and Regulations, except that in each case such counsel need express no opinion with respect to the financial statements or other financial, accounting and reserve data contained in or omitted from the Registration Statement or the Prospectus.

(q) The Partnership is not an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

In rendering such opinion, such counsel may (A) rely in respect of matters of fact upon the representations of the Partnership Parties set forth in this Agreement and upon certificates of officers and employees of the Partnership Entities and upon information obtained from public officials, (B) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (C) state that their opinion is limited to federal laws, the Delaware LP Act and the Delaware LLC Act, (D) with respect to the opinions expressed in subparagraphs (a) through (b) above as to the valid existence, good standing, due qualification or registration as a foreign limited partnership or limited liability company, as the case may be, of the Partnership or the General Partner, state that such counsel relied solely on certificates of foreign qualification or registration provided by the Secretary of State of the states listed on Annex I (each of which will be dated not more than fourteen days prior to the applicable Delivery Date and shall be provided to you), (E) with respect to the opinions expressed in clause (i) of paragraphs (d) and (e) above, respectively, such counsel relied solely on reports, dated as of recent dates, purporting to describe all financing statements on file as of the dates specified therein in the office of the Secretary of the State of Delaware naming the Partnership or the General Partner or one of more or them, as debtors, and (F) state that they express no 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 or any Partnership Entity may be subject.

In addition, such counsel shall state that they have participated in conferences with officers and other representatives of the Partnership Parties and the independent public accountants of the Partnership and your representatives, at which the contents of the Registration Statement, the Pricing Disclosure Package and the Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing upon, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement, the Pricing Disclosure Package and the Prospectus (except to the extent specified in the foregoing opinion), based on the foregoing, no facts have come to such counsel’s attention that lead such counsel to believe that

Exhibit A-3

(A) the Registration Statement, as of the latest Effective Date, 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,

(B) the Pricing Disclosure Package, as of the Applicable Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, or

Ladies and Gentlemen:

The undersigned understands that ▇▇▇▇▇ Fargo Securities, LLC (“▇▇▇▇▇ Fargo”), ▇▇▇▇▇▇▇ Lynch, Pierce, ▇▇▇▇▇▇ & ▇▇▇▇▇ Incorporated, Barclays Capital Inc., Citigroup Global Markets Inc., ▇.▇. ▇▇▇▇▇▇ Securities LLC, RBC Capital Markets, LLC and UBS Securities LLC (the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by the underwriters named therein (the “Underwriters”) from PVR Partners, L.P. (the “Partnership”) of common units representing limited partner interests (the “Common Units”) in the Partnership, and that the Underwriters propose to reoffer such Common Units to the public (the “Offering”).

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of ▇▇▇▇▇ Fargo, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any Common Units (including, without limitation, Common Units that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and Common Units that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for Common Units, whether now owned or hereafter acquired, (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any Common Units or securities convertible into or exercisable or exchangeable for Common Units or any other securities of the Partnership or (4) publicly disclose the intention to do any of the foregoing, for a period commencing on the date hereof and ending on the 60th day after the date of the Prospectus relating to the Offering.

In furtherance of the foregoing, the Partnership and its transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

Exhibit C-1

It is understood that, (i) if the Partnership notifies the Underwriters, or the Underwriters advise the Partnership, in writing, prior to the execution of the Underwriting Agreement, that they have determined not to proceed with the Offering or (ii) if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Units to be included in the Offering, the undersigned will be released from all obligations under this Lock-Up Letter Agreement and this Lock-Up Letter Agreement shall automatically terminate and be of no further force and effect.

The undersigned understands that the Partnership and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

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

[Signature page follows]

Exhibit C-2

The undersigned hereby represents and warrants on the date first written above that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof.
