     (l) Except as described in the Pricing Disclosure Package and the Prospectus, (i) neither the Partnership nor any of its subsidiaries shall have sustained, since the date of the latest audited financial statements included or incorporated by reference in the Pricing Disclosure Package and the Prospectus, 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 capital or long-term debt of the Partnership or any of its subsidiaries or any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), results of operations, unitholders’ equity, properties, management, business or prospects of the Partnership and its subsidiaries taken as a whole, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Representatives, 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 such Delivery Date on the terms and in the manner contemplated in the Pricing Disclosure Package and the Prospectus.
     (m) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in the Common Units shall have been suspended by the Commission or the New York Stock Exchange, (ii) trading in securities generally on the New York Stock Exchange or the American Stock Exchange shall have been suspended or materially limited or the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on the New York Stock Exchange, (iii) a banking moratorium shall have been declared by federal or New York State authorities, (iv) a material disruption in commercial banking or clearance services in the United States, (v) 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 (vi) a calamity or crisis the effect of which on the financial markets is such as to make it, in the sole judgment of the Representatives, impracticable or inadvisable to proceed with the offering or delivery of the Units being delivered on such Delivery Date on the terms and in the manner contemplated in the Pricing Disclosure Package and the Prospectus.
     (n) The New York Stock Exchange shall have approved the Units for listing, subject only to official notice of issuance.
     (o) The Lock-Up Agreements between the Representatives and the persons listed on Schedule IV, delivered to the Representatives on or before the date of this Agreement, shall be in full force and effect on such Delivery Date, except to the extent waived, released, suspended or terminated in writing by the Representatives.
     All such opinions, certificates, letters and documents 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 the Underwriters and to counsel for the Underwriters.
     8. Indemnification and Contribution.
     (a) Each of the Enterprise Parties, jointly and severally, agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of any Underwriter and

22


 

each person who controls any Underwriter within the meaning of either the Securities Act or the Exchange Act from and against any and all losses, claims, damages or liabilities, joint or several, to which that Underwriter, director, officer, employee or controlling person may become subject under the Securities 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 (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Pricing Disclosure Package, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or the omission or the alleged omission to state in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Pricing Disclosure Package, any Issuer Free Writing Prospectus or in any amendment or supplement thereto any material fact required to be stated therein or necessary to make the statements therein 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 Enterprise Parties 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 Enterprise Parties by the Underwriters through the Representatives specifically for inclusion therein, which information consists solely of the information specified in Section 8(b). This indemnity agreement will be in addition to any liability which the Enterprise Parties may otherwise have.
     (b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless each Enterprise Party, the directors of the General Partner, the respective officers of the General Partner who sign the Registration Statement, and each person who controls the Enterprise Parties within the meaning of either the Securities Act or the Exchange Act to the same extent as the foregoing indemnity from the Partnership to the Underwriters, but only with reference to written information relating to the Underwriters furnished to the Partnership by the Underwriters through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Underwriters may otherwise have. The Enterprise Parties acknowledge that the following statements set forth in the most recent Preliminary Prospectus and the Prospectus: (A) the names of the Underwriters, (B) the last paragraph of the cover page regarding delivery of the Units and (C) under the heading “Underwriting,” (1) the sentence relating to concessions, (2) the paragraphs (including the bullet points contained therein) under the heading “Price Stabilization, Short Positions and Penalty Bids,” and (3) the paragraphs under the heading “Electronic Distribution,” constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectuses or in any amendment or supplement thereto.
     (c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or 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 claim or 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

23


 

forfeiture by the indemnifying party of substantive 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 reasonable fees, costs 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 reasonably 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) 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 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 reasonably 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 contain any statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.
     (d) In the event that the indemnity provided in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Enterprise Parties and the Underwriters 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, the “Losses”) to which the Enterprise Parties and the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Enterprise Parties on the one hand and by the Underwriters on the other from the offering of the Units; provided, however, that in no case shall (i) any Underwriter be responsible for any amount in excess of the amount by which the total price of the Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Enterprise Parties and the Underwriters shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Enterprise Parties 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 Enterprise Parties shall be

24


 

deemed to be equal to the total net proceeds from the Offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the 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 Enterprise Parties 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 Enterprise Parties and each of 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), 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. For purposes of this Section 8, each person who controls any Underwriter within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee and agent of any Underwriter shall have the same rights to contribution as the Underwriters, and each person who controls the Enterprise Parties within the meaning of either the Securities Act or the Exchange Act, each officer of the General Partner who shall have signed the Registration Statement and each director of the General Partner shall have the same rights to contribution as the Enterprise Parties, subject in each case to the applicable terms and conditions of this paragraph (d).
     9. No Fiduciary Duty. Each Enterprise Party hereby acknowledges that each Underwriter is acting solely as an underwriter in connection with the purchase and sale of the Units. Each Enterprise Party further acknowledges that each Underwriter is acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s-length basis and in no event do the parties intend that each Underwriter acts or be responsible as a fiduciary to any of the Partnership Entities, their management, unitholders, creditors or any other person in connection with any activity that each Underwriter may undertake or have undertaken in furtherance of the purchase and sale of the Units, either before or after the date hereof. Each Underwriter hereby expressly disclaims any fiduciary or similar obligations to any of the Partnership Entities, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Enterprise Parties hereby confirm their understanding and agreement to that effect. The Enterprise Parties and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriters to any of the Partnership Entities regarding such transactions, including but not limited to any opinions or views with respect to the price or market for the Units, do not constitute advice or recommendations to any of the Partnership Entities. Each Enterprise Party hereby waives and releases, to the fullest extent permitted by law, any claims that any Enterprise Party may have against each Underwriter with respect to any breach or alleged breach of any fiduciary or similar duty to any of the Partnership Entities in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.
     10. Defaulting Underwriters. If, on any Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the Units that the defaulting Underwriter agreed but

25


 

failed to purchase on such Delivery Date in the respective proportions which the number of Firm Units set forth opposite the name of each remaining non-defaulting Underwriter in Schedule I hereto bears to the total number of Firm Units set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule I hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Units on such Delivery Date if the total number of Units that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 10% of the total number of Units to be purchased on such Delivery Date, and any remaining non-defaulting Underwriters shall not be obligated to purchase more than 110% of the number of Units that it agreed to purchase on such Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Units to be purchased on such Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the Units that the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to any Second Delivery Date, the obligation of the Underwriters to purchase, and of the Partnership to sell, the Option Units) shall terminate without liability on the part of any non-defaulting Underwriters or the Partnership, except that the Partnership will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 12. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule I hereto that, pursuant to this Section 10, purchases Units that a defaulting Underwriter agreed but failed to purchase.
     Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Partnership for damages caused by its default. If other Underwriters are obligated or agree to purchase the Units of a defaulting or withdrawing Underwriter, either the Representatives or the Partnership may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.
     11. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Partnership prior to delivery of and payment for the Firm Units if, prior to that time, any of the events described in Sections 7(l) or 7(m) shall have occurred or if the Underwriters shall decline to purchase the Units for any reason permitted under this Agreement.
     12. Reimbursement of Underwriters’ Expenses. If the sale of the Units provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 7 hereof is not satisfied, because of any termination pursuant to Section 7(m)(i) hereof or because of any refusal, inability or failure on the part of any Enterprise Party to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Underwriters, the Partnership 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 the Underwriters in connection with the proposed purchase and sale of the Units. If this Agreement is terminated pursuant to

26


 

Section 10 hereof by reason of the default of one or more of the Underwriters, the Partnership shall not be obligated to reimburse any defaulting Underwriter on account of such Underwriter’s expenses.
     13. Research Analyst Independence. Each of the Enterprise Parties acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to each of the Enterprise Parties and/or the offering that differ from the views of their respective investment banking divisions. Each of the Enterprise Parties hereby waives and releases, to the fullest extent permitted by law, any claims that the Enterprise Parties may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Partnership by such Underwriters’ investment banking divisions. Each of the Enterprise Parties acknowledges that each of the Underwriters 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.
     14. Issuer Information. Each Underwriter severally agrees that such Underwriter, without the prior written consent of the Partnership, has not used or referred to publicly and shall not use or refer to publicly any “free writing prospectus” (as defined in Rule 405 but excluding any Issuer Free Writing Prospectus identified on Schedule V hereto and any electronic road show constituting a free writing prospectus under Rule 433) required to be filed by the Partnership with the Commission or retained by the Partnership under Rule 433. Any such free writing prospectus consented to by the Representatives or the Partnership is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Partnership 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.
     15. Notices. All statements, requests, notices and agreements hereunder shall be in writing, and:
     (a) if to the Underwriters, shall be delivered or sent by mail or facsimile transmission to Citigroup Global Markets Inc. General Counsel (Fax: (212)  ###-###-####) and confirmed to the General Counsel, Citigroup Global Markets Inc., at 388 Greenwich Street, New York, New York 10013, Attention: General Counsel.

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof.
     The Enterprise Parties shall be entitled to rely upon any request, notice, consent or agreement given or made by the Representatives on behalf of the Underwriters.
     16. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Enterprise Parties and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except as provided in Section 8 with respect to affiliates, officers, directors, employees, representatives, agents and controlling persons of the Partnership, the Operating LLC and the Underwriters. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 16, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.
     17. Survival. The respective indemnities, representations, warranties and agreements of the Enterprise Parties and the Underwriters contained in this Agreement or made by or on behalf on them, respectively, pursuant to this Agreement or any certificate delivered pursuant hereto, shall survive the delivery of and payment for the Units and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any of them or any person controlling any of them. The Underwriters acknowledge and agree that the obligations of the Enterprise Parties hereunder are non-recourse to the General Partner.
     18. Definition of the Terms “Business Day” and “Subsidiary”. For purposes of this Agreement, (a) “business day” means any day on which the New York Stock Exchange, Inc. is open for trading and (b) “affiliate” and “subsidiary” have their respective meanings set forth in Rule 405 of the Rules and Regulations.
     19. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.
     20. Jurisdiction; Venue.

Each of the parties (on its behalf and, to the extent permitted by applicable law, on behalf of its limited partners and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The parties agree that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the parties and may be enforced in any other courts to the jurisdiction of which the parties is or may be subject, by suit upon such judgment.

28


 

     21. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument.
     22. Amendments. No amendment or waiver of any provision of this Agreement, nor any consent or approval to any departure therefrom, shall in any event be effective unless the same shall be in writing and signed by the parties hereto.

EXHIBIT A
FORM OF ISSUER’S COUNSEL OPINION
     1. Each of the General Partner, the Partnership, the Operating LLC and the OLPGP is validly existing in good standing as a limited liability company, limited partnership or corporation, as applicable, under the laws of the State of Delaware or the State of Texas, as the case may be. Each of the General Partner, the Partnership, the Operating LLC and the OLPGP has all necessary limited liability company, limited partnership or corporate, as the case may be, power and authority to (i) execute and deliver, and incur and perform all of its obligations under, the Underwriting Agreement and (ii) own or lease its properties and conduct its businesses and, in the case of the General Partner, to act as the general partner of the Partnership and, in the case of the OLPGP, to act as the sole manager of the Operating LLC, in each case in all material respects as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus.

EXHIBIT B
FORM OF CORPORATE COUNSEL’S OPINION
     1. Each of the Partnership Entities (other than the Enterprise Parties) has been duly formed or incorporated, as the case may be, and is validly existing and in good standing under the laws of its respective jurisdiction of formation with all necessary corporate, limited liability company or limited partnership, as the case may be, power and authority to own or lease its properties and conduct its business, in each case in all material respects as described in each of the Pricing Disclosure Package and the Prospectus. Each of the Partnership Entities (other than the Enterprise Parties) is duly registered or qualified as a foreign corporation, limited partnership or limited liability company, as the case may be, for the transaction of business under the laws of each jurisdiction in which its ownership or lease of property or the conduct of its businesses requires such qualification or registration, except where the failure to so qualify or register would not, individually or in the aggregate, have a Material Adverse Effect.
     2. All of the outstanding shares of capital stock, partnership interests or membership interests, as the case may be, of each of the Partnership Entities (other than the Enterprise Parties) have been duly and validly authorized and issued, are fully paid and non-assessable. Except as described in each of the Pricing Disclosure Package and the Prospectus, the Operating LLC and/or the Partnership, as the case may be, directly or indirectly, owns the shares of capital stock, partnership interests or membership interests, as applicable, in each of the Partnership Entities (other than the Enterprise Parties and the General Partner) as set forth on Schedule III to the Underwriting Agreement, free and clear of any lien, charge, encumbrance, security interest, restriction upon voting or any other claim.
     3. There are no preemptive or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any capital stock or partnership or membership interests or capital stock (a) in the Partnership Entities (other than the Enterprise Parties), in each case, pursuant to the organizational documents of any such entity or (b) in the Partnership Entities pursuant to any agreement or other instrument known to such counsel to which any of them is a party or by which any of them may be bound (other than the organizational documents of such entity). To such counsel’s knowledge, neither the filing of the Registration Statement nor the offering or sale of the Units as contemplated by the Underwriting Agreement gave or gives rise to any rights for or relating to the registration of any Common Units or other securities of the Partnership or any of its subsidiaries, other than as have been waived. To such counsel’s knowledge, except for options granted pursuant to employee benefits plans, qualified unit option plans or other employee compensation plans and the Partnership’s DRIP, there are no outstanding options or warrants to purchase any partnership or membership interests or capital stock in any Partnership Entity.
     4. Each of the Enterprise Parties has all requisite right, power and authority to execute and deliver the Underwriting Agreement and to perform its respective obligations thereunder. The Partnership has all requisite partnership power and authority to issue, sell and deliver the Units in accordance with and upon the terms and conditions set forth in the Underwriting Agreement, the Partnership Agreement, the Registration Statement, the Pricing Disclosure Package and the Prospectus. All action required to be taken by the Enterprise Parties

     5. None of (i) the offering, issuance and sale by the Partnership of the Units, (ii) the execution, delivery and performance of the Underwriting Agreement by the Enterprise Parties, or (iii) the consummation of the transactions contemplated hereby (A) conflicts or will conflict with or constitutes or will constitute a violation of the certificate of limited partnership or agreement of limited partnership, certificate of formation or limited liability company agreement, certificate or articles of incorporation or bylaws or other organizational documents of any of the Partnership Entities (other than the Enterprise Parties), (B) conflicts or will conflict with or constitutes or will constitute a breach or violation of, or a default (or an event that, with notice or lapse of time or both, would constitute such a default) under, any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument known to such counsel to which any of the Partnership Entities is a party or by which any of them or any of their respective properties may be bound, or (C) will result, to the knowledge of such counsel, in any violation of any judgment, order, decree, injunction, rule or regulation of any court, arbitrator or governmental agency or body having jurisdiction over any of the Partnership Entities or any of their assets or properties, or (D) results or will result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of any of the Partnership Entities, which conflicts, breaches, violations, defaults or liens, in the case of clauses (B), (C) or (D), would, individually or in the aggregate, have a material adverse effect on the financial condition, business or results of operations of the Partnership Entities, taken as a whole, or could materially impair the ability of any of the Enterprise Parties to perform its obligations under the Underwriting Agreement.
     6. To the knowledge of such counsel, (a) there is no legal or governmental proceeding pending or threatened to which any of the Partnership Entities is a party or to which any of their respective properties is subject that is required to be disclosed in the Pricing Disclosure Package or the Prospectus and is not so disclosed and (b) there are no agreements, contracts or other documents to which any of the Partnership Entities is a party that are required to be described in the Pricing Disclosure Package or the Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required.
     In addition, such counsel shall state that he has participated in conferences with officers and other representatives of the Partnership Entities, the independent registered public accounting firm for the General Partner and the Partnership, your counsel and your representatives, at which the contents of the Registration Statement, the Pricing Disclosure Package and the Prospectus and related matters were discussed, and, although such counsel has not independently verified, is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of, the statements contained or incorporated by reference in, the Registration Statement, the Pricing Disclosure Package and the Prospectus (except as and to the extent set forth in certain opinions above), on the basis of the foregoing, no facts have come to such counsel’s attention that have led him to believe that (relying to a limited extent with respect to factual matters upon statements by officers and representatives of the General Partner and the Partnership and their subsidiaries):

B-2


 

     (i) the Registration Statement, as of the latest Effective Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

Incorporated, UBS Securities LLC and Wachovia Capital Markets, LLC; provided, however, that with respect to the undersigned, the foregoing restrictions do not apply to (i) sales pursuant to “cashless-broker” exercises of options for Common Units in accordance with the Partnership’s benefit plans as consideration for the exercise price and withholding taxes applicable to such exercises and (ii) transfers to any trust for the direct or indirect benefit of each person or the immediate family; provided that it shall be

     In furtherance of the foregoing, the Partnership and its Transfer Agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.
     It is understood that, if the Partnership notifies you that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof that survive termination) shall terminate or be terminated prior to payment for and delivery of the Units, the undersigned will be released from his obligations under this Lock-Up Letter Agreement.
     The undersigned understands that the Partnership and you will proceed with the Offering in reliance on this Lock-Up Letter Agreement.
     Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Partnership and you.
     The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs and personal representatives, in the case of individuals, or successors and assigns, in the case of nonnatural persons, of the undersigned.
