The Partnership will designate the maximum number of Units to be sold and the minimum price per Unit at which such Units may be sold by such Manager daily as agreed to by such Manager and in any event not in excess of the amount of Units available for issuance under the currently effective Registration Statement and the Prospectus or in excess of the amount of Units authorized from time to time to be issued and sold under this Agreement by the General Partner’s board of directors, or a duly authorized committee thereof, and notified to such Manager in writing. Subject to the terms and conditions hereof, the Manager shall use its commercially reasonable efforts to offer and sell all of the Units designated on any day; provided, however, that such Manager shall have no obligation to offer or sell any Units, and the Partnership acknowledges and agrees that such 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 such 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 such Manager reasonably believes it may be deemed an “underwriter” under the Securities Act in a transaction that is other than by means of ordinary brokers’ transactions on the NYSE that qualify for delivery of a Prospectus in accordance with Rule 153 under the Securities Act.

(ii) Notwithstanding the foregoing, the Partnership, through any of the Authorized Partnership Representatives, may instruct such Manager by telephone (confirmed promptly by electronic mail) or 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 such Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail) or electronic mail, suspend the offering of the Units for any reason and at any time (a “Suspension”); provided, however, that such Suspension shall not affect or impair the parties’ respective obligations with respect to the Units sold hereunder prior to the giving of such notice.

On each Settlement Date, the Units sold through such Manager for settlement on such date shall be issued and delivered by the Partnership to such 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 such Manager’s account, or to the account of such 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 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 such Manager harmless against any loss, claim or damage arising from or as a result of such default by the Partnership and (B) pay such 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).

(vii) At each Time of Sale, Settlement Date, and Delivery Date (as defined in Section 4(q)), the Partnership shall be deemed to have affirmed each representation and warranty contained in this Agreement. Any obligation of any Manager to use its commercially 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, 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.

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.

(b) Each Manager, severally and not jointly, agrees to indemnify, defend and hold harmless the Partnership, its directors and officers, and any person who controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Partnership or any such person may incur under the Securities Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning any Manager furnished in writing by or on behalf of such Manager to the Partnership expressly for use in, the Registration Statement (or in the Registration Statement as amended by any post effective amendment thereof by the Partnership), or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was not contained in such information and which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning any Manager furnished in writing by or on behalf of such Manager to the Partnership expressly for use in, the Prospectus Supplement or arises out of or is based upon any omission or alleged omission to state a material fact in the Prospectus Supplement in connection with such information, which material fact was not contained in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

(c) If any action, suit or proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against the Partnership or any Manager (as applicable, the “indemnifying party”) pursuant to subsection (a) or (b), respectively, of this Section, such indemnified party shall promptly notify such

indemnifying party in writing of the institution of such Proceeding and such indemnifying party shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all fees and expenses; provided, however, that the omission to so notify such indemnifying party shall not relieve such indemnifying party from any liability which such indemnifying party may have to any indemnified party or otherwise. The indemnified party or parties shall have the right to employ its or their own counsel in any such case, but the fees and expenses of such counsel shall be at the expense of such indemnified party or parties unless the employment of such counsel shall have been authorized in writing by the indemnifying party in connection with the defense of such Proceeding or the indemnifying party shall not have, within a reasonable period of time in light of the circumstances, employed counsel to defend such Proceeding or such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from, additional to or in conflict with those available to such indemnifying party (in which case such indemnifying party shall not have the right to direct the defense of such Proceeding on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by such indemnifying party and paid as incurred (it being understood, however, that such indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding). The indemnifying party shall not be liable for any settlement of any Proceeding effected without its written consent but, if settled with its written consent, such indemnifying party agrees to indemnify and hold harmless the indemnified party or parties from and against any loss or liability, as incurred, by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second sentence of this Section 7(c), then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

(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 Managers, 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 relevant Manager(s) severally, 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 relevant 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 discounts and commissions received by the relevant Manager, bear to the aggregate public offering price of the Units. The relative fault of the Partnership, on the one hand, and of the relevant 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 relevant 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 each of the Managers 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, no Manager shall be required to contribute any amount in excess of commissions received by it under this Agreement. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f) The Partnership and each of the Managers 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 General Partner’s officers or directors in connection with the issuance and sale of the Units, or in connection with the Registration Statement or the Base Prospectus.

SECTION 12. No Fiduciary Relationship.

Each Manager hereby expressly disclaims any fiduciary or similar obligations to the Partnership, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Partnership hereby confirms its understanding and agreement to that effect. The Partnership and each of the Managers agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by any Manager to the Partnership regarding such transactions, including, but not limited to, any opinions or views with respect to the price or market for the Partnership’s securities, do not constitute advice or recommendations to the Partnership.

SECTION 17. Law; Construction.

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 any Manager or any indemnified party. Each of the Managers and the Partnership (on behalf of themselves and, to the extent permitted by applicable law, on behalf of their respective securityholders and affiliates) waive 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.

If the foregoing correctly sets forth the understanding between the Partnership and the Managers, please so indicate in the space provided below for that purpose, whereupon this Agreement and your acceptance shall constitute a binding agreement between the Partnership and the Managers. Alternatively, the execution of this Agreement by the Partnership and its acceptance by or on behalf of the Managers may be evidenced by an exchange of telegraphic or other written communications.

	By:	/s/ Peter J. Gvazdauskas
		Peter J. Gvazdauskas
		Chief Financial Officer and Treasurer

(a) The Partnership is validly existing in good standing as a limited partnership under the Delaware LP Act with all necessary limited partnership power and authority to own its properties and to conduct its business as described in the Prospectus. The Partnership has been duly registered or qualified as a foreign limited partnership for the transaction of business under the laws of each jurisdiction set forth opposite its name in Annex I to this opinion.

(b) The General Partner is the sole general partner of the Partnership with a 1.6% general partner interest in the Partnership; such general partner interest has been duly authorized and validly issued in accordance with the Partnership Agreement; and the General Partner owns such general partner interest free and clear of all liens, encumbrances (except restrictions on transferability as set forth in the Partnership Agreement), security interests, charges or claims (i) in respect of which a financing statement under the Uniform Commercial Code of the Commonwealth of Pennsylvania naming the General Partner as debtor is on file in the office of the Secretary of the Commonwealth of the Commonwealth of Pennsylvania or (ii) otherwise known to such counsel, without independent investigation, other than those created by or arising under the Delaware LP Act.

(c) The General Partner owns all of the Incentive Distribution Rights; and all of the Incentive Distribution Rights have been duly authorized and validly issued in accordance with the Partnership Agreement, and are fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act and except as described in the Prospectus); and the General Partner owns the Incentive Distribution Rights free and clear of all liens, encumbrances (except with respect to the Incentive Distribution Rights and restrictions on transferability as set forth in the Partnership Agreement), security interests, charges or claims (i) in respect of which a financing statement under the Uniform Commercial Code of the Commonwealth of Pennsylvania naming the General Partner as debtor is on file in the office of the Secretary of the Commonwealth of the Commonwealth of Pennsylvania or (ii) otherwise known to such counsel, without independent investigation, other than those created by or arising under the Delaware LP Act.

(d) Upon due action by an Authorized Partnership Representative pursuant to Section 3(a)(i) of the Agreement and by Michael J. Hennigan, in his capacity as the member of the Pricing Committee of the Board of Directors of the General Partner in accordance with the resolutions adopted by the Board of Directors of the General Partner on January 15, 2015 and October 19, 2015 relating to the authorization of the Registration Statement and the authorization of the issuance and sale of the Units (the “Resolutions”), the Units to be issued and sold by the Partnership pursuant to the Agreement and the limited partner interests represented thereby will have been duly authorized and, when issued and delivered against payment therefor in accordance with the terms of the Agreement (or the Terms Agreement, if applicable), will be validly issued, fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act and except as described in the Prospectus).

(e) Except as described in the Registration Statement or provided for in the Partnership Agreement and for rights that have been waived, (i) no person has the right to require the registration under the Securities Act of any securities of the Partnership and (ii) there are no rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any partnership or member interests in any of the Partnership Entities, in each case, pursuant to any agreement or other instrument to which any such

Partnership Entity is a party or by which any of them may be bound listed as an exhibit to the Registration Statement, the Partnership’s most recent Annual Report on Form 10-K and any Quarterly Reports on Form 10-Q filed subsequent thereto or any Current Reports on Form 8-K filed by the Partnership since the beginning of the current calendar year.

(f) The Partnership has all necessary limited partnership power and authority to issue, sell and deliver the Units, in accordance with and upon the terms and conditions set forth in the Agreement, the Partnership Agreement, the Resolutions, the Registration Statement and Prospectus.

(g) The Agreement has been duly authorized and validly executed and delivered by the Partnership.

(h) Assuming due authorization, execution and delivery by the General Partner of the Partnership Agreement, the Partnership Agreement constitutes a valid and legally binding obligation of each of the Partnership Entities who are parties thereto, enforceable against each such Partnership Entity in accordance with its respective terms, subject to (A) 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 (B) public policy, applicable law relating to fiduciary duties and indemnification and contribution and an implied covenant of good faith and fair dealing.

(i) None of the offering, issuance and sale by the Partnership of the Units, the execution, delivery and performance of the Agreement by the Partnership or the consummation of the transactions contemplated thereby (i) constitutes or will constitute a violation of the agreement of limited partnership, limited liability company agreement or any other governing document of the Partnership or any Material Subsidiary, (ii) constitutes or will constitute a breach or violation of, or a default (or an event that, with notice or lapse of time or both, would constitute such a default) under, any agreement filed as an exhibit to the Registration Statement, the Partnership’s most recent Annual Report on Form 10-K and any Quarterly Reports on Form 10-Q filed subsequent thereto or any Current Reports on Form 8-K filed by the Partnership since the beginning of the current calendar year, (iii) violates or will violate the Delaware LP Act, the Delaware LLC Act, New York law or federal law, or (iv) results or will result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Partnership or any Subsidiary, which conflicts, breaches, violations, defaults or liens, in the case of clauses (ii), (iii) or (iv), would, individually or in the aggregate, have a material adverse effect on the consolidated financial condition, business, assets or results of operations of the Partnership and its consolidated subsidiaries taken as a whole; provided, however, that no opinion need be expressed pursuant to the preceding clause (iii) in relation to any federal or state securities laws, tax laws or anti-fraud laws.

(j) No permit, consent, approval, authorization, order, registration, filing or qualification (“consent”) under the Delaware LP Act, the Delaware LLC Act, New York law or federal law is required for the offering, issuance and sale by the Partnership of the Units, the execution, delivery and performance of the Agreement by the Partnership, or the consummation of the transactions contemplated thereby, except (i) for such consents required under the Securities Act or the Exchange Act or under state securities or “Blue Sky” laws, as to which such counsel need not express any opinion, (ii) for such consents that have been obtained or made, (iii) for such consents that, if not obtained or made, would not, individually or in the aggregate, have a material adverse effect on the consolidated financial condition, business, assets or results of operations of the Partnership and its consolidated subsidiaries taken as a whole or (iv) as disclosed in the Prospectus.

(k) The statements contained in the Registration Statement and the Prospectus under the captions “Cash Distributions,” “Conflicts of Interest and Fiduciary Responsibilities” and “Description of

the Common Units,” insofar as they constitute descriptions of legal proceedings or documents referred to therein or refer to statements of law or legal conclusions, are accurate in all material respects; and the Units conform as to legal matters in all material respects to the descriptions thereof contained in the Registration Statement and the Prospectus.

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

(m) The Registration Statement was declared effective on September 10, 2015; with your consent, based solely on a review of the list of stop orders contained on the Commission’s website at http://www.sec.gov/litigation/stoporders.shtml and http://www.sec.gov/litigation/admin.shtml on December 4, 2015, we confirm that no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings for that purpose have been initiated by the Commission; and the filing of the Prospectus pursuant to Rule 424(b) has been made in the manner and within the time period required by such Rule.

(n) The Registration Statement, as of the latest Effective Date, and the Prospectus, as of its date (except for the financial statements and the notes and the schedules thereto and the other financial, accounting and related statistical data included in the Registration Statement or the Prospectus, as to which such counsel need not express any opinion), comply as to form in all material respects with the requirements of the Securities Act and the Rules and Regulations.

(o) None of the Partnership Entities is an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.

In addition, such counsel shall state that, because it has not conducted any independent investigation or verification with regard to the information set forth in the Registration Statement or the Prospectus (except to the extent set forth in paragraphs (k) and (l) above), such counsel is not (except as aforesaid) passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements contained therein. Such counsel shall state it has participated, however, in conferences with officers and other representatives of the General Partner and the Partnership, representatives of the independent registered public accounting firms of the General Partner and the Partnership and your representatives, at which the contents of the Registration Statement and the Prospectus and related matters were discussed. Based on the foregoing (relying as to factual matters in respect of the determination of materiality to a significant extent upon statements made by officers and other representatives of the General Partner and the Partnership), such counsel shall state no facts have come to such counsel’s attention that lead such counsel to believe that (i) the Registration Statement (other than (A) the financial statements included or incorporated by reference therein, including the notes and schedules thereto and the auditors’ reports thereon and (B) the other financial and accounting data included or incorporated by reference therein, as to which such counsel need not comment), as of the most recent 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 [Note: initial opinion to be dated as of the date of program commencement; subsequent opinions to be dated as of the applicable Delivery Date], it being understood that such counsel expresses no comment with respect to representations and warranties and other statements of fact included in exhibits to the Registration Statement, or (ii) the Prospectus (other than (A) the financial statements included or incorporated by reference therein, including the notes and schedules thereto and the auditors’ reports thereon and (B) the other financial and accounting data included or incorporated by reference therein, as to which such counsel need not comment), as of its date and as of the date hereof, contained or contains an untrue statement of a material fact or omitted 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.

Such counsel’s opinion may be limited to matters governed by the federal laws of the United States of America to the extent specifically referred to therein, the Delaware LP Act, the Delaware LLC Act, and the laws of the State of New York and such counsel need not express any opinion as to the law of any other jurisdiction. Such counsel need not express any opinion with respect to the title of any of the Partnership Entities to any of their respective real or personal property, and such counsel need not express any 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 any of the Partnership Entities may be subject.

Capitalized terms used herein without definition shall have the respective meanings ascribed to them in the Agreement to which this Exhibit is attached.

(a) The General Partner has been duly formed and is validly subsisting as a limited liability company under the Pennsylvania LLC Act with all necessary limited liability company power and authority to own or lease its properties and assets and to conduct its business as general partner of the Partnership as described in the GP LLC Agreement and pursuant to the Pennsylvania LLC Act.

(b) The Partnership Agreement has been duly authorized and validly executed and delivered by the General Partner.

(c) The GP LLC Agreement constitutes a valid and legally binding obligation of the members of the General Partner, enforceable against each such member in accordance with its terms, subject to (A) 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 (B) public policy, applicable laws relating to fiduciary duties and indemnification and contribution and an implied covenant of good faith and fair dealing.

(d) None of the execution, delivery and performance of the Agreement by the Partnership, and the consummation of the transactions contemplated thereby, (i) constitutes or will constitute a violation of the GP LLC Agreement or the General Partner’s certificate of formation, (ii) constitutes or will constitute a breach or violation of, or a default (or an event that, with notice and lapse of time or both, would constitute such a default) under, any agreement, to which the General Partner is a party, filed as an exhibit to the Registration Statement, the Partnership’s most recent Annual Report on Form 10-K and any Quarterly Reports on Form 10-Q filed subsequent thereto or any Current Reports on Form 8-K filed by the Partnership since the beginning of the current calendar year, or (iii) violates or will violate any present statute, rule or regulation promulgated by the United States or the Commonwealth of Pennsylvania which in such counsel’s experience is normally applicable both to limited liability companies which are not engaged in regulated business activities and to transactions of the type contemplated by the Agreement. Such counsel is not aware of any orders, judgments, decrees or injunctions of any court or governmental agency or body directed to the General Partner or any of its properties in a proceeding to which it or its property is subject that would impair the ability to consummate the transactions contemplated by the Agreement.

(e) No permit, consent, approval, authorization, order, registration, filing or qualification (“consent”) of or with any court, governmental agency or body of the Commonwealth of Pennsylvania having jurisdiction over the General Partner or any of its properties is required for the execution, delivery and performance of the Agreement by the Partnership or the consummation of the transactions contemplated thereby, except for such consents (i) required under the Securities Act, the Exchange Act and state securities or “Blue Sky” laws, as to which no opinion need be expressed, (ii) which have been obtained or made; (iii) which are of a routine or administrative nature expected in the reasonable judgment of such counsel to be obtained in the ordinary course of business; or (iv) which are disclosed in the Prospectus.

In rendering such opinion, among other customary exceptions, qualifications and limitations, such counsel may (A) rely in respect of matters of fact upon the representations of the Partnership set forth in

the Agreement and in certificates of officers and employees of the Partnership and upon information obtained from public officials, (B) assume that all documents submitted to such counsel as originals are authentic, that all copies submitted to such counsel conform to the originals thereof, and that the signatures on all documents examined by such counsel are genuine, (C) state that such opinions are limited to federal laws (exclusive of patent law) and the laws of the Commonwealth of Pennsylvania and (D) state that such counsel expresses no opinion with respect to state or local taxes or tax statutes to which any of the limited partners of the Partnership may be subject.
