Certain terms used herein are defined in Section 21 hereof.

1.Representations and Warranties. (i) The Company, the Operating Partnership and the General Partner, jointly and severally, represent and warrant to, and agree with, each Underwriter as set forth below in this Section 1(i).

(a) The Company meets the requirements for use of Form S-3 under the Act and has prepared and filed with the Commission not earlier than three years prior to the date hereof a registration statement (Reg. No. 333-186316) on Form S-3, including a related Basic Prospectus, for registration under the Act of the offering and sale of the Securities. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, have become effective.

(i) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Selling Unitholder agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Selling Unitholder, at the purchase price set forth in Schedule I hereto, the number of Underwritten Securities opposite such Underwriter’s name in Schedule II hereto.

(b) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Selling Unitholder hereby grants an option to the several Underwriters to purchase, severally and not jointly, up to the number of Option Securities set forth in Schedule I hereto at the same purchase price per share as the Underwriters shall pay for the Underwritten Securities. Said option may be exercised in whole or in part at any time and from time to time on or before the 30th day after the date of the Final Prospectus upon written notice by the Representatives to the Company and the Selling Unitholder setting forth the number of Option Securities as to which the several Underwriters are exercising the option and the settlement date. The number of Option Securities to be purchased by each Underwriter shall be the same percentage of the total number of Option Securities to be purchased by the several Underwriters as such Underwriter is purchasing of the Underwritten Securities, subject to such adjustments as you in your absolute discretion shall make to eliminate any fractional shares.

3. Delivery and Payment. Delivery of and payment for the Underwritten Securities and the Option Securities (if the option provided for in Section 2(b) hereof shall have been exercised before the Closing Date) shall be made on the date specified in Schedule I hereto or at such time on such later date

not more than three Business Days after the foregoing date as the Representatives shall designate, which date may be postponed by agreement among the Representatives, the Company and the Selling Unitholder or as provided in Section 9 hereof (such date and time of delivery and payment for the Securities being herein called the “Closing Date”). Delivery of the Securities shall be made to the Representatives for the respective accounts of the several Underwriters against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the order of the Selling Unitholder by wire transfer payable in same-day funds to an account specified by the Selling Unitholder. Delivery of the Securities shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct.

The Selling Unitholder will pay all applicable state transfer taxes, if any, involved in the transfer to the several Underwriters of the Securities to be purchased by them from the Selling Unitholder and the respective Underwriters will pay any additional stock transfer taxes involved in further transfers.

If the option provided for in Section 2(b) hereof is exercised on or after the Closing Date, the Selling Unitholder will deliver the Option Securities (at the expense of the Company) to the Representatives, through the facilities of The Depository Trust Company, on the date specified by the Representatives (which shall be within three Business Days after exercise of said option) for the respective accounts of the several Underwriters, against payment by the several Underwriters through the Representatives of the purchase price thereof to or upon the order of the Selling Unitholder by wire transfer payable in same-day funds to an account specified by the Selling Unitholder. If settlement for the Option Securities occurs after the Closing Date, the Selling Unitholder and the Company will deliver to the Representatives on the settlement date for the Option Securities, and the obligation of the Underwriters to purchase the Option Securities shall be conditioned upon receipt of, supplemental opinions, certificates and letters confirming as of such date the opinions, certificates and letters delivered on the Closing Date pursuant to Section 6 hereof.

4. Offering by Underwriters. It is understood that the several Underwriters propose to offer the Securities for sale to the public as set forth in the Disclosure Package and the Final Prospectus.

5. Agreements. (i) The Company, the Operating Partnership and the General Partner, jointly and severally, agree with the several Underwriters that:

(a) Prior to the termination of the offering of the Securities, the Company will not file any amendment of the Registration Statement or supplement (including the Final Prospectus or any Preliminary Prospectus) to the Basic Prospectus or any Rule 462(b) Registration Statement unless the Company has furnished you a copy for your review prior to filing and will not file any such proposed amendment, supplement or Rule 462(b) Registration Statement to which you reasonably object. The Company will cause the Final Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Representatives with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Representatives of such timely filing. The Company will promptly advise the Representatives, prior to the termination of the offering of the Securities, (i) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (ii) when any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Final Prospectus or for any additional information relating to the offering of the Securities, (iv) of

the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice that would prevent its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or prevention and, upon such issuance, occurrence or prevention, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or prevention, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement become or be declared effective as soon as practicable.

(b) If, at any time prior to the filing of the Final Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, the Company will (i) notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package in a form approved by the Representatives, such approval not to be unreasonably withheld, conditioned or delayed, to correct such statement or omission; and (iii) supply any amendment or supplement to you in such quantities as you may reasonably request.

(c) If, at any time when a prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus (as it may be then supplemented) would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Final Prospectus to comply with the Act, including in connection with use or delivery of the Final Prospectus, the Company promptly will (i) notify the Representatives of such event, (d) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment to the Registration Statement or supplement to the Final Prospectus which will correct such statement or omission or effect such compliance and (i) supply any supplemented Final Prospectus to you in such quantities as you may reasonably request.

(e) As soon as practicable, the Company will make generally available to its security holders and to the Representatives an earnings statement or statements of the Company and its consolidated subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158.

(f) The Company will furnish to the Representatives, upon request, and counsel for the Underwriters, upon request, without charge, signed copies of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Representatives may reasonably request. The Company will pay the expenses of printing or other production of all documents relating to the offering.

(g) The Company will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives may designate, will maintain such qualifications in effect so long as required for the distribution of the Securities and will pay any fee of FINRA in connection with its review of the offering; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject.

(h) The Company agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute a “free writing prospectus” (as defined in Rule 405) required to be filed with the Commission or retained by the Company under Rule 433. Any such free writing prospectus consented to by the Representatives or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(i) The Company will not, without the prior written consent of UBS Securities LLC, offer, sell, contract to sell, pledge, grant any options or warrants to purchase Common Units or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or the General Partner of the Company or any person in privity with the Company or any affiliate of the Company (other than each executive officer of the General Partner who is providing to the Underwriters a letter substantially in the form of Annex I hereto pursuant to Section 6(j) hereto), directly or indirectly), including through the filing (or participation in the filing) of a registration statement with the Commission in respect of, or the establishment of or increase in a put equivalent position in or liquidation or the decrease in a call equivalent position in, within the meaning of Section 16 of the Exchange Act, any Common Units or rights that represent the right to receive Common Units or any securities that are senior to or pari passu with Common Units or publicly announce an intention to effect any such transaction, for a period of forty-five (45) days from the Execution Time, other than pursuant to employee benefit plans or unit option plans, or upon the conversion or exchange of convertible or exchangeable securities outstanding as of the date of this Agreement. For the avoidance of doubt, neither Energy Transfer Partners, L.P., nor any of its subsidiaries, including Heritage ETC, L.P., is an affiliate of the Company.

(j) The Company will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(k) The Company agrees to pay the costs and expenses relating to the following matters: (i) the preparation, printing or reproduction and filing with the Commission of the Registration Statement (including financial statements and schedules and exhibits thereto), each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus relating to the Underwritten

Securities, and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus, and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Securities; (iv) the registration of the Securities under the Act and the listing of the Securities on the New York Stock Exchange; (v) any registration or qualification of the Securities for offer and sale under the securities or blue sky laws of the several states (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such registration and qualification) and the preparation, printing and delivery to the Underwriters of copies of the blue sky survey and any supplement thereto; (vi) any filings required to be made with FINRA (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such filings); (vii) the fees and expenses of the Company’s accountants and of ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ LLP and the fees and expenses of counsel (including local and special counsel) for the Company; the fees and expenses of the transfer agent; and (viii) all other costs and expenses incident to the performance by the Company of its obligations hereunder.

(ii) The Selling Unitholder agrees with the several Underwriters that:

(a) The Selling Unitholder will not, without the prior written consent of UBS Securities LLC, offer, sell, contract to sell, pledge, or otherwise dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Selling Unitholder or any person in privity with the Selling Unitholder or any affiliate of the Selling Unitholder, directly or indirectly), including through the filing (or participation in the filing) of a registration statement with the Commission other than the Registration Statement in respect of, or the establishment of or increase in a put equivalent position in or liquidation or the decrease in a call equivalent position in, within the meaning of Section 16 of the Exchange Act, any Common Units (other than (x) the Securities to be sold pursuant to this Agreement and (y) any Common Units sold or transferred by the Selling Unitholder to any of its affiliates, provided, in the case of this clause (y), that each recipient of such Common Units shall have, prior to any such receipt, entered into a written lock-up agreement with the Representatives that is identical in all material respects to this Section 5(ii)(a) with respect to the then-remaining portion of the Lock-up Period (as defined below)) or rights that represent the right to receive Common Units or any securities that are senior to or pari passu with Common Units or publicly announce an intention to effect any such transaction, for a period of forty-five (45) days from the Execution Time (the “Lock-Up Period”).

(b) The Selling Unitholder will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities.

(c) The Selling Unitholder will advise you promptly, and if requested by you, will confirm such advice in writing, so long as delivery of a prospectus relating to the Securities by an underwriter or dealer may be required under the Act, of any change in the Selling Unitholder Information which comes to the attention of the Selling ▇▇▇▇▇▇▇▇▇▇.

▇▇

(▇) The Selling Unitholder represents that it has not prepared or had prepared on its behalf or used or referred to, and agrees that it will not prepare or have prepared on its behalf or use or refer to, any Free Writing Prospectus, and has not distributed and will not distribute any written materials in connection with the offer or sale of the Securities.

(c) The Representatives shall have received from ▇▇▇▇▇ ▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the sale of the Securities, the Disclosure Package, the Final Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Company and the Selling Unitholder shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters.

(d) The Company shall have furnished to the Representatives a certificate, signed by the President or any Vice President and the principal financial or accounting officer of the General Partner, dated the Closing Date, to the effect that:

(iii) the representations and warranties of the Company, the Operating Partnership and the General Partner in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Company, the Operating Partnership and the General Partner have complied, in all material respects, with

(f) (i) The Company shall have requested and caused PricewaterhouseCoopers LLP, an independent registered public accounting firm, to have furnished to the Representatives, at the Execution Time and at the Closing Date, letters, dated respectively as of the Execution Time and as of the Closing Date, in form and substance satisfactory to the Representatives.

7. Reimbursement of Underwriters’ Expenses.

Underwriters pursuant to Sections 9 or 10 hereof, the Company will reimburse the Underwriters severally, through the Representatives on demand, for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities. If the Company is required to make any payments to the Underwriters under this Section 7 because of the Selling Unitholder’s refusal, inability or failure to satisfy any condition to the obligations of the Underwriters set forth in Section 6, the Selling Unitholder shall reimburse the Company on demand for all amounts so paid.

It is understood that, except as otherwise provided in this Agreement, the Underwriters will pay all their own costs and expenses, including the fees of their counsel, transfer taxes on any transfers of the Securities by the Underwriters and any advertising expenses connected with any offer they make and the transportation and other expenses incurred by the Underwriters in connection with presentations to prospective purchasers of the Securities.

8. Indemnification and Contribution.

(a) (i) The Company, the Operating Partnership and the General Partner, jointly and severally, agree to indemnify and hold harmless each Underwriter, the directors, officers, employees, agents and affiliates of each Underwriter and each person who controls any Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (ii) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement for the registration of the Securities as originally filed or in any amendment thereof or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any untrue statement or alleged untrue statement of any material fact contained in the Basic Prospectus, any Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, or the omission or alleged omission to state therein a material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company, the Operating Partnership and the General Partner will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company, the Operating Partnership and the General Partner by or on behalf of any Underwriter through the Representatives specifically for inclusion therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below. This indemnity agreement will be in addition to any liability which the Company, the Operating Partnership and the General Partner may otherwise have.

(ii) The Selling Unitholder agrees to indemnify and hold harmless the Company, the Operating Partnership and the General Partner, each of their respective directors and each of their respective officers who signs the Registration Statement, each Underwriter, the directors, officers, employees, agents and affiliates of each Underwriter and each person who controls the Company or any Underwriter within the meaning of either the Act or the Exchange Act, to the same extent as

the foregoing indemnity from the Company to each Underwriter, but only with reference to the Selling Unitholder Information. This indemnity agreement will be in addition to any liability which any Selling Unitholder may otherwise have. The liability of the Selling Unitholder under the indemnity agreement contained in this Section 8(a)(ii) shall be limited to an amount equal to the total gross proceeds from the sale of the Securities by the Selling Unitholder under the Agreement.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Company, the Operating Partnership and the General Partner, each of their respective directors, each of their respective officers who signs the Registration Statement, and each person who controls the Company, the Operating Partnership and the General Partner within the meaning of either the Act or the Exchange Act, and the Selling Unitholder, to the same extent as the foregoing indemnity from the Company, the Operating Partnership and the General Partner to each Underwriter, but only with reference to written information furnished to the Company, the Operating Partnership and the General Partner by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter: the information regarding the offering price and sales through affiliates appearing in the third full paragraph under the caption “Underwriters” and the information regarding stabilizing transactions, over-allotment transactions, syndicate covering transactions, and penalty bids appearing in the ninth full paragraph under the caption “Underwriting.” This indemnity agreement will be in addition to any liability which any Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) based on the advice of counsel, the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded, based on the advice of counsel, that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not,

without the prior written consent of the indemnified parties, 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 parties. An indemnifying party will not be liable for any settlement of any action or claim effected without its written consent (which consent will not be unreasonably withheld).

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company, the Operating Partnership, the General Partner, and the Selling Unitholder on the one hand and the Underwriters on the other severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively “Losses”) to which the Company, the Operating Partnership, the General Partner, and the Selling Unitholder and one or more of the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company, the Operating Partnership, the General Partner and the Selling Unitholder on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case under this paragraph (d) shall any Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by such Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Company, the Operating Partnership, the General Partner, and the Selling Unitholder on the one hand and the Underwriters on the other severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company, the Operating Partnership, the General Partner, and the Selling Unitholder on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Company, the Operating Partnership, the General Partner, and the Selling Unitholder shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by the Selling Unitholder, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Company, the Operating Partnership, the General Partner and the Selling Unitholder on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Company, the Operating Partnership, the General Partner and the Selling Unitholder and the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), (x) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation and (y) the Selling Unitholder shall not be required to contribute to any Losses, except for such Losses arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, the Basic Prospectus, any Preliminary Prospectus, the Final Prospectus or

any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with the Selling Unitholder Information. For purposes of this Section 8, each person who controls an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee, agent and affiliate of an Underwriter shall have the same rights to contribution as such Underwriter and each person who controls the Company, the Operating Partnership and the General Partner within the meaning of either the Act or the Exchange Act, each officer of the Company, the Operating Partnership and the General Partner who shall have signed the Registration Statement and each director of the Company, the Operating Partnership and the General Partner shall have the same rights to contribution as the Company, the Operating Partnership and the General Partner, subject in each case to the applicable terms and conditions of this paragraph (d).

(e) The Company, the Operating Partnership, the General Partner and the Selling Unitholder may agree, as among themselves and without limiting the rights of the Underwriters under this Agreement, as to the respective amounts of any liability under the indemnity and contribution agreements contained in Section 8 for which they each shall be responsible.

9. Default by an Underwriter. (vii) If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated severally to take up and pay for (in the respective proportions which the amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; (viii) provided, however, that in the event that the aggregate amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate amount of Securities set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter, the Selling Unitholder or the Company. In the event of a default by any Underwriter as set forth in clause (ii) of this Section 9, the Closing Date shall be postponed for such period, not exceeding seven days, as the Representatives and Company shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Company, the Selling Unitholder and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, by notice given to the Company prior to delivery of and payment for the Securities, if at any time prior to such time (iii) trading in the Company’s securities shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange, (iv) a banking moratorium shall have been declared either by Federal or New York State authorities or (v) 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 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 by the Final Prospectus (exclusive of any supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Company, the Operating Partnership and the General Partner or their officers, of the Selling Unitholder and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of any Underwriter, the Selling Unitholder or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

Furthermore, the Company, the Operating Partnership, the General Partner and the Selling Unitholder agree that they are solely responsible for making their own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Company or the Selling Unitholder on related or other matters). The Company, the Operating Partnership, the General Partner and the Selling Unitholder agree that they will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company or the Selling Unitholder, in connection with such transaction or the process leading thereto.

15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company, the Operating Partnership and the General Partner or the Selling Unitholder and the Underwriters, or any of them, with respect to the subject matter hereof.
