3. Sale and Delivery of Offered Units.

(a) Sale of Offered Units by the Manager, as Sales Agent. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to issue and sell Offered Units from time to time through the Manager, acting as sales agent, and the Manager agrees to use its commercially reasonable efforts to sell, as sales agent for the Company, the Offered Units on the following terms.

(i) The Offered Units are to be sold on a daily basis or otherwise as shall be agreed to by the Company and the Manager on any day that (A) is a trading day for the NYSE (other than a day on which the NYSE is scheduled to close prior to its regular weekday closing time), (B) the Company, through any of the individuals listed as Authorized Representatives on Schedule III hereto, has instructed the Manager by telephone (confirmed promptly by electronic mail) to make such sales and (C) the Company has satisfied its obligations under Section 6 of this Agreement. The Company will designate the maximum amount of the Offered Units to be sold by the Manager daily as agreed to by the Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and the minimum price per

Unit at which such Offered Units may be sold. Subject to the terms and conditions hereof, the Manager shall use its commercially reasonable efforts to sell on a particular day all of the Offered Units designated for sale by the Company on such day. The gross sales price of the Offered Units sold under this Section 3(a) shall be the market price for the Common Units sold by the Manager under this Section 3(a) on the NYSE at the time of sale of such Offered Units.

(ii) The Company acknowledges and agrees that (A) there can be no assurance that the Manager will be successful in selling the Offered Units, (B) the Manager will incur no liability or obligation to the Company or any other person or entity if it does not sell Offered Units for any reason other than a failure by the Manager to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Offered Units as required under this Agreement, and (C) the Manager shall be under no obligation to purchase Offered Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by the Manager and the Company in writing pursuant to a Terms Agreement.

(iii) The Company shall not authorize the issuance and sale of, and the Manager shall not be obligated to use its commercially reasonable efforts to sell, any Offered Units at a price lower than the minimum price therefor designated from time to time by the Company’s Board of Directors (the “Board”), or a duly authorized committee thereof, and notified to the Manager in writing. The Company or the Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail), suspend the offering of the Offered Units for any reason and at any time; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Offered Units sold hereunder prior to the giving of such notice.

(iv) The Manager hereby covenants and agrees not to make any sales of the Offered Units on behalf of the Company, pursuant to this Section 3(a), other than (A)(1) by means of ordinary brokers’ transactions between members of the NYSE, any other national securities exchange or facility thereof, a trading facility of a national securities association, or an alternative trading system that qualify for delivery of a Prospectus to the NYSE in accordance with Rule 153 under the Act, (2) to or through a market maker, or (3) directly on or through an electronic communication network, a “dark pool” or any similar market venue and (B) such other sales of the Offered Units on behalf of the Company in its capacity as agent of the Company as shall be agreed by the Company and the Manager pursuant to a Terms Agreement.

(v) The compensation to the Manager for sales of the Offered Units with respect to which the Manager acts as sales agent under this Agreement shall be up to 2.0% of the gross sales price of the Offered Units sold pursuant to this Section 3(a) and payable as described in subsection (vii) below. The foregoing rate of compensation shall not apply when the Manager acts as principal, in which case the Company may sell Offered Units to the Manager as principal at a price

agreed upon at the relevant Applicable Time pursuant to a Terms Agreement. The gross proceeds less the Manager’s commission, shall constitute the net proceeds to the Company for such Offered Units (the “Net Proceeds”). Payment of the Net Proceeds after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales (the “Transaction Fees”), for Offered Units sold by the Company on any Settlement Date shall be made to the Company by federal funds wire transfer to the account of the Company against delivery of such Offered Units to the Manager’s account, or an account of the Manager’s designee, at The Depository Trust Company (“DTC”).

(vi) The Manager shall provide written confirmation (which may be by facsimile or electronic mail) to the Company following the close of trading on the NYSE each day in which the Offered Units are sold under this Section 3(a) setting forth the number of the Offered Units sold on such day, the aggregate gross sales proceeds and the Net Proceeds to the Company, and the compensation payable by the Company to the Manager with respect to such sales. Such compensation shall be set forth and invoiced in periodic statements from the Manager to the Company, with payment to be made by the Company promptly after its receipt thereof.

(vii) Settlement for sales of the Offered Units pursuant to this Section 3(a) will occur on the third Business Day following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Offered Units sold through the Manager for settlement on such date shall be issued and delivered by the Company to the Manager against payment of the Net Proceeds for the sale of such Offered Units. Settlement for all such Offered Units shall be effected by free delivery of the Offered Units to the Manager’s account at DTC in return for payments in same day funds delivered to the account designated by the Company. If the Company or its transfer agent (if applicable) shall default on its obligation to deliver the Offered Units on any Settlement Date, the Company shall (A) indemnify and hold the Manager harmless against any loss, claim or damage arising from or as a result of such default by the Company and (B) pay the Manager any commission to which it would otherwise be entitled absent such default. If the Manager breaches this Agreement by failing to deliver the Net Proceeds less any Transaction Fees to the Company on any Settlement Date for the Offered Units delivered by the Company, the Manager will pay the Company interest based on the effective overnight federal funds rate on such unpaid amount less any compensation due to the Manager.

(viii) At each Applicable Time, Settlement Date and Representation Date (as defined in Section 4(k)), the Company shall be deemed to have affirmed each representation and warranty contained in this Agreement (and any certificate delivered pursuant to Section 3(e) that remains in effect at such time or date) as if such representation and warranty were made as of such date, modified as necessary to relate to the Registration Statement and the Prospectus as amended

as of such date. Any obligation of the Manager to use its commercially reasonable efforts to sell the Offered Units on behalf of the Company shall be subject to the continuing accuracy of the representations and warranties of the Company herein, to the performance by the Company of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 6 of this Agreement.

(b) Sale of Common Units by the Manager, as Principal. If the Company wishes to issue and sell the Offered Units pursuant to this Agreement but other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify the Manager of the proposed terms of such Placement. If the Manager, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Company wishes to accept amended terms, the Manager and the Company will enter into a Terms Agreement setting forth the terms of such Placement. The terms set forth in a Terms Agreement will not be binding on the Company or the Manager unless and until the Company and the Manager have each executed such Terms Agreement accepting all of the terms of such Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement will control.

(c) Terms Agreement. Each sale of the Offered Units to the Manager shall be made in accordance with the terms of this Agreement and, if applicable, a Terms Agreement, which will provide for the sale of such Offered Units to, and the purchase thereof by, the Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Offered Units by the Manager. The commitment of the Manager to purchase the Offered Units pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties of the Company herein contained and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the number of the Offered Units to be purchased by the Manager pursuant thereto, the price to be paid to the Company for such Offered Units, any provisions relating to rights of, and default by, underwriters acting together with the Manager in the reoffering of the Offered Units, and the time and date (each such time and date being referred to herein as a “Time of Delivery”) and place of delivery of and payment for such Offered Units. Such Terms Agreement shall also specify any requirements for opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 6 of this Agreement and any other information or documents required by the Manager.

Under no circumstances shall the number and aggregate amount of the Offered Units sold pursuant to this Agreement and any Terms Agreement exceed (i) the aggregate amount set forth in Section 1, (ii) the number of Common Units available for issuance under the currently effective Registration Statement or (iii) the number and aggregate amount of the Offered Units authorized from time to time to be issued and sold under this Agreement by the Board, or a duly authorized committee thereof, and notified to the Manager in writing.

(e) Regulation M. Each of the Company and the Manager acknowledges that, as of the date hereof, the Common Units are not an “actively traded security” exempt from the requirements of Rule 101 of Regulation M under the Exchange Act by subsection (c)(1) of such rule (an “Actively Traded Security”). In the event the Common Units become an Actively

Traded Security, the Company will notify the Manager of such event as soon as practicable, and deliver to the Manager a certificate (the “Regulation M Certificate”) of the Company signed by its Chief Executive Officer and its Chief Financial Officer, stating that the Company represents, on the date specified in such certificate, that the Common Units are an Actively Traded Security. Notwithstanding any other provision of this Agreement, the Company shall not request the sale of any Offered Units that would be sold, and the Manager shall not be obligated to sell any Offered Units, unless and until the condition in Section 6(m) is satisfied. Further, in the event that the Common Units have become an Actively Traded Security, and then either party has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Common Units, it shall notify the other party of such change as soon as practicable, and further sales of the Offered Units under this Agreement and any Terms Agreement (but not settlement of sales that occurred when the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act were satisfied) shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(f) Ratings Downgrade. If there is any decrease in the rating of any of the Company’s debt securities by any “nationally recognized statistical rating organization” (as such term is defined under Section 3(a)(62) of the Exchange Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change, the Company will notify the Manager of such event as soon as practicable, and the Company shall not request the sale of any Offered Units, and the Manager shall not be obligated to sell any Offered Units, unless it agrees to act as sales agent pursuant to this Agreement.

(g) Material Non-Public Information. Notwithstanding any other provision of this Agreement, the Company shall not request the sale of any Offered Units that would be sold, and the Manager shall not be obligated to sell any Offered Units, during any period in which the Company is, or it is reasonably likely that it is, in possession of material non-public information; provided that, for any such period, unless otherwise agreed between the Company and the Manager, for purposes of this paragraph (f), such period shall end on the date on which the Company’s next Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be, is filed with the Commission.

The Company has properly completed the Prospectus, in a form approved by the Manager, and filed such Prospectus, as amended at the Execution Time, with the Commission pursuant to the applicable paragraph of Rule 424(b) by the Execution Time and will cause any supplement to the Prospectus to be properly completed, in a form approved by the Manager, and will file such

The Company will use its commercially reasonable efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its commercially reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

The Company will pay the expenses of printing or other production of all documents relating to the offering.

(g) No Issuer Free Writing Prospectus. The Company agrees that, unless it has or shall have obtained the prior written consent of the Manager, and the Manager agrees with the Company that, unless it has or shall have obtained, 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 Offered Units that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule II hereto. Any such free writing prospectus consented to by the Manager or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (ii) 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.

7. Indemnification and Contribution.

(a) The Company agrees to indemnify and hold harmless the Manager, the directors, officers, employees, affiliates and agents of the Manager and each person who controls the Manager 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 any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Offered Units as originally filed or in any amendment thereof, or in the Base Prospectus, the Prospectus Supplement, the Prospectus, or any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto or arise out of or are based upon 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, 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 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 by the Manager specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Company may otherwise have.

(b) The Manager agrees to indemnify and hold harmless the Company, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Company within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Company to the Manager, but only with reference to written information relating to the Manager furnished to the Company by the Manager specifically for inclusion in the documents referred to in the foregoing indemnity, which information is limited to the name and the address of the Manager. This indemnity agreement will be in addition to any liability which the Manager may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 7 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 7, 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) 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 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.

(d) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Company and the Manager agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Company and the Manager may be subject in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and by the Manager on the other from the offering of the Offered Units; provided, however, that in no case shall the Manager be responsible for any amount in excess of the underwriting discount or commission, as the case may be, applicable to the Offered Units purchased by the Manager hereunder. If the allocation provided by the immediately preceding sentence is

unavailable for any reason, the Company and the Manager severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Company on the one hand and of the Manager 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 shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Manager shall be deemed to be equal to the total underwriting discounts and commissions, in each case as determined by this Agreement or any applicable Terms Agreement. 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 on the one hand or the Manager 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 and the Manager 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 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person who controls the Manager within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of the Manager shall have the same rights to contribution as the Manager, and each person who controls the Company within the meaning of either the Act or the Exchange Act, each officer of the Company who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company, subject in each case to the applicable terms and conditions of this paragraph (d).

(d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Manager or the Company, as the case may be. If such termination shall occur prior to the Settlement Date or Time of Delivery for any sale of the Offered Units, such sale shall settle in accordance with the provisions of Section 3(a)(vii) of this Agreement.

(e) In the case of any purchase of the Offered Units by the Manager pursuant to a Terms Agreement, the obligations of the Manager pursuant to such Terms Agreement shall be subject to termination, in the absolute discretion of the Manager, by notice given to the Company prior to the Time of Delivery relating to such Offered Units, if at any time prior to such delivery and payment (i) trading in the Company’s Common Units shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchanges, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) 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 Manager, impractical or inadvisable to proceed with the offering or delivery of the Offered Units as contemplated by the Prospectus (exclusive of any amendment or supplement thereto).

9. Representations and Indemnities to Survive. The respective agreements, representations, warranties and indemnities of the Company and of the Manager set forth in or made pursuant to this Agreement by or on behalf of them, respectively, will remain in full force and effect, regardless of any investigation made by the Manager or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Offered Units.

12. No fiduciary duty. The Company hereby acknowledges that (a) the purchase and sale of the Offered Units pursuant to this Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the Manager and any affiliate through which it may be acting, on the other, (b) the Manager is acting solely as sales agent and/or principal in connection with the purchase and sale of the Company’s securities and not as a fiduciary of the Company and (c) the Company’s engagement of the Manager in connection with the offering and the process leading up to the offering is as independent contractor and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether the Manager has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Manager has rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

Exhibit A - 3

to which any of them or their respective property is a party or (D) results or will result in the creation or imposition of any Lien upon any property or assets of any of the Company Entities under any agreement or instrument filed as an exhibit to the Registration Statement to which any of the Company Entities is a party or by which any of them or any of their respective properties may be bound, which 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 or would materially impair the ability of the Company to consummate the transactions provided for in this Agreement or any applicable Terms Agreement.

15. No permit, consent, approval, authorization, order, registration, filing or qualification (“consent”) of or with any U.S. Federal or Delaware court, governmental agency or body, or under the Delaware LLC Act, the Delaware LP Act, the DGCL or federal law is required in connection with the offering, issuance or sale by the Company of the Offered Units, the application of the proceeds therefrom as described under “Use of Proceeds” in the Disclosure Package and the Prospectus, the execution, delivery and performance of this Agreement and any applicable Terms Agreement by the Company, or the consummation by the Company of the transactions contemplated by this Agreement or any applicable Terms Agreement other than those (i) for registration of the Offered Units under the Act and filings and consents required under the Exchange Act, (ii) applicable state securities or “Blue Sky” laws of any jurisdiction, as to which such counsel need not express any opinion, (iii) that have been obtained or made and (iv) that, if not obtained, would not, individually or in the aggregate, have a Material Adverse Effect.

The statements set forth in the Prospectus under the captions “How We Make Cash Distributions,” “Description of the Common Units” and “The Operating Agreement” insofar as they purport to constitute summaries of provisions of federal or New York statutes, rules or regulations, the Delaware LP Act or the Delaware LLC Act or of any specific agreement or instrument, constitute accurate summaries thereof in all material respects; and the descriptions of the Common Units contained in the Prospectus under the captions “Prospectus Summary—The Offering,” “How We Make Cash Distributions,” “Description of the Common Units” and “The Operating Agreement” constitute accurate summaries of the terms of the Common Units in all material respects, provided, however, that such counsel need not express any opinion with respect to any laws other than the laws of the State of Delaware and the federal laws of the United States.

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

amendments and supplements thereto made by the Company prior to the date of such opinion letter (other than the financial statements, the notes and schedules thereto and other financial data included in or omitted from the Registration Statement or the Prospectus, as to which such counsel need not express any opinion) appear on their face to comply as to form in all material respects with the requirements of the Act.

20. The Company is not, and after sale of the Offered Units to be sold by the Company hereunder and application of the net proceeds from such sale as described in the Disclosure Package and the Prospectus under the caption “Use of Proceeds,” will not be, an “investment company” within the meaning of the Investment Company Act.

In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon certificates of officers and other employees of the Company Entities and upon information obtained from public officials, (ii) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (iii) state that their opinion is limited to federal laws, the Delaware LP Act, the Delaware LLC Act and the DGCL, (iv) with respect to the opinions expressed as to the due qualification or registration as a foreign corporation, limited partnership or limited liability company, as the case may be, of the Niska-Delaware Group Entities, state that such opinions are based upon certificates of foreign qualification or registration provided by the Secretary of State of the states listed on an annex to be attached to such counsel’s opinion (each of which shall be dated as of a date not more than fourteen days prior to the applicable Time of Delivery and shall be provided to counsel to the Manager) and express no conclusions beyond what are stated in such certificates, (v) state that they express no opinion with respect to (A) any permits to own or operate any real or personal property or (B) state or local taxes or state or local tax statutes to which any of the members of the Company or any of the Company Entities may be subject, and (vi) with respect to the existence of any Lien for which a financing statement under the Uniform Commercial Code of any state is on file, such counsel’s opinion is based solely upon such counsel’s review of a specific search of such state’s Secretary of State (each of which shall be as of a date not more than fourteen days prior to the applicable Time of Delivery and shall be provided to counsel to the Manager).

In addition, such counsel shall state that they have participated in conferences with officers and other representatives of the Company and the independent registered public accounting firm of the Company, and representatives of the Manager, at which the contents of the Registration Statement, the Disclosure Package and the Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing upon, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement, the Disclosure Package and the Prospectus (except to

Exhibit A - 5

the extent specified in the foregoing opinion), based on the foregoing, no facts have come to such counsel’s attention that lead such counsel to believe that:

(A) the Registration Statement, on 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,

(B) the Disclosure Package, as of the Applicable Time, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or
