(2) the Prospectus has been timely filed with the Commission in accordance withSection 5(a)(i) of this Agreement; no stop order suspending the effectiveness of the Registration Statement or any part thereof has been issued; and no proceedings for that purpose have been instituted or, to the knowledge of such officers, threatened by the Commission; all requests of the Commission, if any, for inclusion of additional information in the Registration Statement or the Prospectus or otherwise has been complied with; and the Commission has not notified the Issuers of any objection to the use of the form of the Registration Statement or any post-effective amendment thereto; and

(j) None of the Partnership Entities shall have sustained, since the date of the latest audited financial statements included or incorporated by reference in the Preliminary Prospectus (i) any material loss or interference with its business from fire, explosion, flood, accident or other

(k) Subsequent to the execution and delivery of this Agreement, (i) no downgrading shall have occurred in the rating accorded the debt securities of any of the Partnership Entities that are rated by any “nationally recognized statistical rating or organization” (as that term is defined by the Commission for purposes of Section 3(a)(62) of the Exchange Act) and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any debt securities of any of the Partnership Entities.

Section 8.Indemnification and Contribution.

(a) Each of the Partnership Parties, jointly and severally, shall indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter, affiliates of any Underwriter who have participated in the distribution of the Securities as underwriters, 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 Securities), to which that Underwriter, director, officer, employee, agent, affiliate 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) the 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 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 (D) any material or information provided to investors by, or with the approval of, the Partnership in connection with the marketing or the offering of the Securities other than those described inclauses (A)-(C) above (the “Marketing Materials”), (ii) the omission or alleged omission to state in the 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, or Marketing Materials, any material fact required to be stated therein or necessary to make the statements therein (in the case of all of the foregoing, other than the Registration Statement, in the light of the circumstances under which such statements were made) not misleading, or (iii) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Securities or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered byclause (i) or(ii) above (provided that the Partnership Parties shall not be liable under thisclause (iii) to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct), and shall reimburse each Underwriter and each such director, officer, employee, agent, affiliate or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee, agent, affiliate 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 the 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 or any Marketing Materials, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Partnership Parties through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information specified inSection 8(e) hereof. The foregoing indemnity agreement is in addition to any liability which the Partnership Parties may otherwise have to any Underwriter or to any director, officer, employee, agent, affiliate or controlling person of that Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Partnership Parties, their respective employees, the officers and directors of the General Partner and the OLP GP, and each person, if any, who controls 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 officer, director, 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 the 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 (ii) the omission or alleged omission to state in the 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 (in the case of all of the foregoing, other than the Registration Statement, in the 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 such Underwriter furnished to the Partnership Parties through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth inSection 8(e) hereof. The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the Partnership Parties or any such officer, director, employee or controlling person.

(c) Promptly after receipt by an indemnified party under thisSection 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 thisSection 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 thisSection 8 except to the extent it has been materially prejudiced 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 thisSection 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 thisSection 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 Representatives shall have the right to employ counsel to represent jointly the Representatives and those other Underwriters and their respective directors, officers, employees, agents, affiliates and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Partnership Parties under thisSection 8 if, (i) the Partnership Parties and the Underwriters shall have so mutually agreed; (ii) the Partnership Parties have failed within a reasonable time to retain counsel reasonably satisfactory to the Underwriters; (iii) the Underwriters and their respective directors, officers, employees, agents, affiliates 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 Partnership Parties; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Underwriters or their respective directors, officers, employees, agents, affiliates or controlling persons, on the one hand, and the Partnership Parties, 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 Partnership Parties. 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 thisSection 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party underSection 8(a) or8(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 Parties, on the one hand, and the Underwriters on the other, from the offering of the Securities or (ii) if the allocation provided byclause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to inclause (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 Parties, 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 Securities purchased under this Agreement (before deducting expenses) received by the Operating 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 Securities 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 thisSection 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) 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 thisSection 8(d) shall be deemed to include, for purposes of thisSection 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 thisSection 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Securities underwritten by it exceeds the amount of any damages that such 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. The Underwriters’ obligations to contribute as provided in thisSection 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Partnership Parties acknowledge and agree that the statements regarding delivery of the Securities by the Underwriters set forth on the cover page of, and the concession and reallowance figures and the paragraphs relating to stabilization by the Underwriters appearing under the caption “Underwriting” in, the Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Partnership Parties by or on behalf of the Underwriters specifically for inclusion in the Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials.

Section 9.Defaulting Underwriters.

(a) If, on the Delivery Date, any Underwriter defaults in its obligations to purchase the principal amount of Notes which it has agreed to purchase under this Agreement, the remaining non-defaulting Underwriters may in their discretion arrange for the purchase of such principal amount of Notes by the non-defaulting Underwriters or other persons satisfactory to the Partnership Parties on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such principal amount of Notes, then the Partnership Parties shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such principal amount of Notes on such terms. In the event that within the respective prescribed periods, the non-defaulting Underwriters notify the Partnership Parties that they have so arranged for the purchase of such principal amount of Notes, or the Partnership Parties notify the non-defaulting Underwriters that they have so arranged for the purchase of such principal amount of Notes, either the non-defaulting Underwriters or the Partnership Parties 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 Parties or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement, and the Partnership agrees to promptly prepare any amendment or supplement to the Registration Statement, the Prospectus or in any such other document or arrangement that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed inSchedule 1 hereto that, pursuant to thisSection 9, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the principal amount of Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Partnership Parties as provided inSection 9(a), the total principal amount of Notes that remains unpurchased does not exceed one-eleventh of the total aggregate principal amount of all of the Notes, then the Partnership Parties shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the total principal amount of Notes that such Underwriter agreed to purchase hereunder) of the principal amount of Notes of such defaulting Underwriter or Underwriters for which such arrangements have not been made;

provided that the non-defaulting Underwriters shall not be obligated to purchase more than 110% of the total principal amount of Notes that it agreed to purchase on the Delivery Date pursuant to the terms ofSection 2.

(c) If, after giving effect to any arrangements for the purchase of the principal amount of Notes of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Partnership Parties as provided inSection 9(a), the total principal amount of Notes that remains unpurchased exceeds one-eleventh of the total aggregate principal amount of all of the Notes, or if the Partnership Parties shall not exercise the right described inSection 9(b), then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters except that the provisions ofSection 8 shall not terminate and shall remain in effect. Any termination of this Agreement pursuant to thisSection 9 shall be without liability on the part of the Issuers, except that the Issuers will continue to be liable for the payment of expenses as set forth inSections 6 and11 and except that the provisions ofSection 8 shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Partnership Parties or any non-defaulting Underwriter for damages caused by its default.

Section 10.Termination.

The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Issuers prior to delivery of and payment for the Securities, if at any time prior to such delivery and payment, (i) trading in any securities of the Issuers shall have been suspended on any exchange or in the over-the-counter market by the Commission or the NYSE, (ii) trading in securities generally on the NYSE, NYSE Alternext US, the Nasdaq Stock Market, or in the over-the-counter market shall have been suspended or limited or minimum prices shall have been established on any such exchange or market by the Commission, by such exchange, or by any other regulatory body or governmental authority, (iii) a banking moratorium shall have been declared either by Federal or New York State authorities, or (iv) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis, the effect of which on financial markets in the United States is such as to make it, in the sole judgment of the Representatives, impractical or inadvisable to proceed with the offering, sale or delivery of the Securities as contemplated in the Preliminary Prospectus or the Final Prospectus (exclusive of any amendment or supplement thereto).

Section 11.Reimbursement of Underwriters’ Expenses.

If the Issuers shall fail to tender the Securities 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 to the Underwriters’ obligations hereunder required to be fulfilled by any of the Partnership Parties is not fulfilled for any reason the Partnership Parties will 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 Securities, and upon demand the Partnership Parties shall pay the full amount thereof to the Representatives. If this

(p) The statements contained in the Pricing Disclosure Package and the Prospectus under the caption “Certain United States Federal Income Tax Considerations,” insofar as such statements purport to refer to statements of law or legal conclusions, are accurate and complete in all material respects.

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, the Pricing Disclosure Package or the Prospectus (except to the extent set forth in paragraphs (l) and (p) 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.

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 the financial statements, schedules or other financial data, included therein, incorporated by reference therein, or omitted therefrom and the Form T-1 of the Trustee, 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, 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, (ii) the Pricing Disclosure Package (other than the financial statements, schedules or other financial data, included therein, incorporated by reference therein, or omitted therefrom, as to which such counsel need not comment), as of the Applicable Time, contained an untrue statement of a material fact or omitted 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, or (iii) the Prospectus (other than the financial statements, schedules or other financial data, included therein, incorporated by reference therein, or omitted therefrom, as to which such counsel need not comment), as of its date and the Delivery Date, 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.
