expected to have, individually or in the aggregate, a Material Adverse Effect; the Partnership has fulfilled and performed all its material obligations with respect to such rights-of-way, and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or would result in any impairment of the rights of the Partnership with respect to such rights-of-way, except for such revocations, terminations and impairments that could not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect; and none of such rights-of-way contains any restriction that is materially burdensome to the Partnership.

(v) Permits. The Partnership and each of its subsidiaries have such permits, licenses, patents, franchises, certificates of need and other approvals, consents or authorizations of governmental or regulatory authorities (“Permits”) as are necessary under applicable law to own their properties and conduct their businesses in the manner described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, except for any of the foregoing that could not, in the aggregate, reasonably be expected to have a Material Adverse Effect; each of the Partnership and its subsidiaries has fulfilled and performed all of its obligations with respect to the Permits, and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or results in any other impairment of the rights of the holder or any such Permits, except for any of the foregoing that could not reasonably be expected to have a Material Adverse Effect.

(q) Each Selling Unitholder (or the Custodian or one or more attorneys-in-fact on behalf of such Selling Unitholder) shall have furnished to the Underwriter on the Delivery Date a certificate, dated the Delivery Date, stating that such Selling Unitholder has carefully examined the Registration Statement, the Prospectus and the Pricing Disclosure Package, and the information with respect to such Selling Unitholder contemplated by Section 4(g) is true and correct in all material respects and did not and does not contain any untrue statement of a material fact and did not and does 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 Registration Statement, in the light of the circumstances under which they were made) not misleading.

(r) None of the Trust, the Underlying Properties, the PCEC Parties or any of the Partnership’s subsidiaries shall have sustained, since the date of the latest audited financial statements included or incorporated by reference in the Pricing Disclosure Package, any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree or (ii) since such date there shall not have been any change in the capitalization or long-term debt of the Trust or the Partnership or any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), results of operations, properties or business of the Trust or the Partnership, the effect of which, in any such case described in clause (i) or (ii), is, individually or in the aggregate, in the judgment of the Underwriter, 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 Delivery Date on the terms and in the manner contemplated in the Pricing Disclosure Package.

(s) 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 New York Stock Exchange, The NASDAQ Global Select Market, The NASDAQ Global Market, The NASDAQ Capital Market or The American Stock Exchange or in the over-the-counter market, or trading in Trust Units on any exchange or in the over-the-counter market, shall have been suspended or materially limited or the settlement and clearance 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 general moratorium on commercial banking activities 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) 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 Underwriter, impracticable or inadvisable to proceed with the public offering or delivery of the Units being delivered on the Delivery Date on the terms and in the manner contemplated in the Pricing Disclosure Package.

(t) On or prior to the Delivery Date, the Trust and the PCEC Parties shall have furnished to the Underwriter such further certificates and documents as the Underwriter may reasonably request.

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

12. Indemnification and Contribution.

(a) The PCEC Parties, jointly and severally, and the Trust each hereby agrees to indemnify and hold harmless the Underwriter, its directors, officers, employees, agents and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and any “affiliate” (within the meaning of Rule 405 under the Securities Act) of the Underwriter participating in the offering of the Units, 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 Units), to which the Underwriter, affiliate, 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, (C) any “issuer information” (as defined in Rule 433 under the Securities Act) in any “free writing prospectus” (as defined in Rule 405 under the Securities Act) used or referred to by the Underwriter with the prior consent of the Trust and the Partnership (any such issuer information with respect to whose use the Trust and the Partnership has given its consent, “Permitted Issuer Information”), (D) any materials or information provided to investors by, or with the approval of, the Trust and the PCEC Parties in connection with the marketing of the offering of the Units, including any “road show” (as defined in Rule 433 under the Securities Act) not constituting an Issuer Free Writing Prospectus (“Marketing Materials”), (E) any Blue Sky application or other document prepared or executed by the PCEC Parties or the Trust (or based upon any written information furnished by the PCEC Parties or the Trust for use therein) specifically for the purpose of qualifying any or all of the Units under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”) or (F) any Testing-the-Waters Communication or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in light of the circumstances under which they were made) not misleading, and shall reimburse the Underwriter and each such affiliate, director, officer, employee, agent or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Underwriter, affiliate, 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 neither the PCEC Parties nor the Trust shall 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, any Marketing Materials or any Blue Sky Application, in reliance upon and in conformity with written information concerning the Underwriter furnished to the Trust by the Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 12(g). The foregoing indemnity agreement

is in addition to any liability which the PCEC Parties or the Trust may otherwise have to the Underwriter or to any affiliate, director, officer, employee, agent or controlling person of the Underwriter.

(b) Each Selling Unitholder, severally in proportion to the number of Units to be sold by each of them and not jointly, shall indemnify and hold harmless the Underwriter, its directors, officers, employees, agents and each person, if any, who controls the Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and any “affiliate” (within the meaning of Rule 405 under the Securities Act) of the Underwriter participating in the offering of the Units, 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 Units), to which the Underwriter, affiliate, 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 any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or any “free writing prospectus” (as defined in Rule 405), prepared by or on behalf of the Selling Unitholder or used or referred to by the Selling Unitholder in connection with the offering of the Units in violation of Section 9(a) (a “Selling Unitholder Free Writing Prospectus”), or in any Marketing Materials, (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, 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 the Selling Unitholder furnished to the Trust specifically for inclusion therein, and shall reimburse the Underwriter and each such affiliate, director, officer, employee, agent or controlling person promptly upon demand for any legal or other expenses reasonably incurred by the Underwriter, affiliate, 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 or (iii) any breach of any certificate or other agreement delivered pursuant hereto or contemplated hereby; provided, however, that the Selling Unitholder 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 Marketing Materials, in reliance upon and in conformity with written information concerning the Underwriter furnished to the Trust by the Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 12(g). The liability of the Selling Unitholder under the indemnity agreement contained in this paragraph shall be limited to an amount equal to the total gross proceeds from the offering of the Units purchased under the Agreement received by

the Selling Unitholder, as set forth in the table on the cover page of the Prospectus. The foregoing indemnity agreement is in addition to any liability which the Selling Unitholder may otherwise have to the Underwriter or to any affiliate, director, officer, employee, agent or controlling person of the Underwriter.

(c) The Underwriter shall indemnify and hold harmless the Trust, the PCEC Parties, each Selling Unitholder, their respective trustees, directors, officers and employees, and each person, if any, who controls the Trust, the PCEC Parties or each Selling Unitholder within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Trust, the PCEC Parties, such Selling Unitholder or any such trustee, director, 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 in any Marketing Materials or Blue Sky Application, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, 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 the Underwriter furnished to the Partnership or the Trust by the Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 12(g). The foregoing indemnity agreement is in addition to any liability that the Underwriter may otherwise have to the Trust, the PCEC Parties, such Selling Unitholder or any such trustee, director, officer, employee or controlling person.

(d) Promptly after receipt by an indemnified party under this Section 12 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 12, 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 12 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, 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 12. 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 12 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 trustees, 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 12 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 trustees, 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 trustees, 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 (x) 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 a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, or (y) 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.

(e) Notwithstanding the foregoing, the Trust shall not be obligated to make any payments to an indemnified party under this Section 12 until the earlier to occur of the following: (a) with respect to a final, nonappealable judgment of a court of competent jurisdiction or a settlement agreement, neither PCEC Party has paid such indemnified party the amount owed within 30 days of the due date under such judgment or settlement, (ii) with respect to expenses, neither PCEC Party has paid such indemnified party the amount owed within 30 days of submission by the indemnified party for reimbursement of such expenses or (iii) the Partnership or the General Partner shall become the subject of any bankruptcy or insolvency proceedings or publicly declares its inability to pay its debts as they become due.

(f) If the indemnification provided for in this Section 12 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 12(a), 12(b) or 12(c) 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 PCEC Parties, the Selling Unitholders and the Trust, on the one hand, and the Underwriter, 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 PCEC Parties, the Selling Unitholders and the Trust, on the one hand, and the Underwriter, 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 PCEC Parties, the Selling Unitholders and the Trust, on the one hand, and the Underwriter, 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 PCEC Parties, the Selling Unitholders and the Trust, 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 Underwriter 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 Trust, the PCEC Parties, the Selling Unitholders or the Underwriter, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Trust, the PCEC Parties, the Selling Unitholders and the Underwriter agree that it would not be just and equitable if contributions pursuant to this Section 12(f) 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 12(f) shall be deemed to include, for purposes of this Section 12(f), 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 12(f), in no event shall the Underwriter be required to contribute any amount in excess of the total underwriting discounts and commissions received by the Underwriter with respect to the offering of the Units exceeds the amount of any damages that the Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(g) The Underwriter confirms and the Trust, the Selling Unitholders and the PCEC Parties acknowledge and agree that the (i) first sentence under “Commissions and Expenses” and (ii) paragraphs under “Stabilization and Short Positions,” each under the caption “Underwriting” in the most recent Preliminary Prospectus and Prospectus are correct and constitute the only information concerning the Underwriter furnished in writing to the Partnership by or on behalf of the Underwriter specifically for inclusion in

any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials.

13. [RESERVED]

14. Termination. The obligations of the Underwriter hereunder may be terminated by the Underwriter by notice given to and received by the Partnership and the Trust prior to delivery of and payment for the Units if, prior to that time, any of the events described in Sections 11(r) and 11(s) shall have occurred or if the Underwriter shall decline to purchase the Units for any reason permitted under this Agreement.

15. Reimbursement of Underwriter’s Expenses. If (a) the Partnership shall fail to tender the Units for delivery to the Underwriter for any reason, or (b) the Underwriter shall decline to purchase the Units for any reason permitted under this Agreement, the PCEC Parties will reimburse the Underwriter for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Underwriter) incurred by the Underwriter in connection with this Agreement and the proposed purchase of the Units, and upon demand the PCEC Parties shall pay the full amount thereof to the Underwriter.

16. Research Analyst Independence. Each of the PCEC Parties, the Selling Unitholders and the Trust acknowledges that the Underwriter’s research analysts and research department are required to be independent from its investment banking division and are subject to certain regulations and internal policies, and that the Underwriter’s research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Partnership, the Trust and/or the offering that differ from the views of its investment banking division. Each of the PCEC Parties, the Selling Unitholders and the Trust hereby waives and releases, to the fullest extent permitted by law, any claims that the PCEC Parties, the Selling Unitholders or the Trust, as the case may be, may have against the Underwriter with respect to any conflict of interest that may arise from the fact that the views expressed by its independent research analysts and research department may be different from or inconsistent with the views or advice communicated to the PCEC Parties, the Selling Unitholders or the Trust by the Underwriter’s investment banking division. Each of the PCEC Parties, the Selling Unitholders and the Trust acknowledges that the 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.

17. No Fiduciary Duty. The PCEC Parties, the Selling Unitholders and the Trust each acknowledges and agrees that in connection with this offering and sale of the Units or any other services the Underwriter 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 Underwriter: (a) no fiduciary or agency relationship between the PCEC Parties, the Selling Unitholders, the Trust and any other person, on the one hand, and the Underwriter, on the other, exists; (b) the Underwriter is not acting as an advisor, expert or otherwise, to either the PCEC Parties, the Selling Unitholders or the Trust,

including, without limitation, with respect to the determination of the public offering price of the Units, and such relationship between the PCEC Parties, the Selling Unitholders and the Trust, on the one hand, and the Underwriter, on the other, is entirely and solely commercial, based on arms-length negotiations; (c) any duties and obligations that the Underwriter may have to the PCEC Parties, the Selling Unitholders or the Trust shall be limited to those duties and obligations specifically stated herein; and (d) the Underwriter and its affiliates may have interests that differ from those of the PCEC Parties, the Selling Unitholders and the Trust. The PCEC Parties, the Selling Unitholders and the Trust each hereby waives any claims that the PCEC Parties, the Selling Unitholders or the Trust may have against the Underwriter with respect to any breach of fiduciary duty in connection with this offering.

18. Notices, etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

(a) if to the Underwriter, shall be delivered or sent by mail or facsimile transmission to ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC, ▇▇▇▇ ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇, Attention: Equity Syndicate Desk, with a copy to the Legal Department;

19. Persons Entitled to Benefit of Agreement.

Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 19, any legal or equitable right, remedy or claim

under or in respect of this Agreement or any provision contained herein. Nothing in this Agreement shall affect or modify in any respect the provisions of Section 6 of the Registration Rights Agreement dated as of May 8, 2012 between the Partnership and the Trust.

20. Survival. The respective indemnities, representations, warranties and agreements of the PCEC Parties, the Selling Unitholders, the Trust and the Underwriter contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Units and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them.

21. Definition of the Terms “Business Day”, “Affiliate” and “Subsidiary”.

9. The Registration Statement, on the latest Effective Date, and the Prospectus, as of its date and the date hereof, each appeared on their face to be appropriately responsive in all material respects to the requirements of the Act; except that in each case such counsel need express no view with respect to Regulation S-T or the oil and gas reserves data, or other financial data, included or omitted from, the Registration Statement or the Prospectus. For purposes of this paragraph, such counsel may assume that the statements made in the Registration Statement and the Prospectus are correct and complete.

FORM OF OPINION OF DAY ▇▇▇▇▇▇ & ▇▇▇▇▇▇ LLP

1. The Conveyance has caused all right, title and interest of the Partnership in and to the Conveyed Interests to be conveyed to the Trust and has caused the Conveyed Interests to constitute fully conveyed and vested real property interests.

Such purchasers and creditors of the Partnership will be deemed to purchase with notice of, and subject to, such Conveyed Interests.

In rendering such opinion, such counsel may state that its opinion is limited to matters governed by the laws of the State of California.
