It is understood that the Underwriters propose to offer the Units to the public upon the terms and conditions set forth in the Registration Statement hereinafter defined. 3. PURCHASE, SALE AND DELIVERY OF THE OPTION UNITS. The Partnership hereby grants an option to the Underwriters to purchase from the Partnership up to 540,000 Option Units, on the same terms and conditions as the Firm Units; provided, however, that such option may be exercised only for the purpose of covering any over-allotments that may be made by the Underwriters in the sale of the Firm Units.

Such registration statement and any post-effective amendments thereto have become effective under the 1933 Act. The Company also has filed, or proposes to file, with the SEC pursuant to Rule 424(b) of the 1933 Act Rules and Regulations, a prospectus supplement specifically relating to the Units. Copies of such registration statement, including any amendments thereto, each related prospectus contained therein, and the exhibits, financial statements and schedules thereto have heretofore been delivered by the Partnership to the Underwriters. The term "REGISTRATION STATEMENT" as used herein means the registration statement as amended at the time it became effective under the 1933 Act (the "EFFECTIVE DATE"), including financial statements and all exhibits and any information deemed to be part of the Registration Statement pursuant to Rule 430A or 430C of the 1933 Act Rules and Regulations. If it is contemplated, at the time this Agreement is executed, that a post-effective amendment to such registration statement will be filed and must be declared effective before the offering of Units may commence, the term "REGISTRATION STATEMENT" as used herein means the registration statement as amended by said post-effective amendment. The term "PROSPECTUS" as used herein means the base prospectus in the form included in the Registration Statement at the time it was declared effective (the "BASE PROSPECTUS") together with the prospectus supplement relating to the offering of the Units dated the date hereof in the form first filed with the SEC on or after the date hereof pursuant to Rule 424(b) under the 1933 Act (the "PROSPECTUS SUPPLEMENT"). Any preliminary form of the Prospectus which has heretofore been filed with the SEC pursuant to Rule 424(b) is herein called the "PRELIMINARY PROSPECTUS". Any reference in this Agreement to the registration statement, the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act, as of the date of the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Prospectus Supplement or the Prospectus, as the case may be, and any reference to any amendment or supplement 3 to the Registration Statement, the Base Prospectus, the Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any documents filed after such date under the Securities Exchange Act of 1934, as amended (the "1934 ACT"), and the rules and regulations thereunder (the "1934 ACT RULES AND REGULATIONS"), which, upon filing, are incorporated by reference therein, as required by paragraph (b) of Item 12 of Form S-3. As used herein, the term "INCORPORATED DOCUMENTS" means the documents which are incorporated by reference in the Registration Statement, Preliminary Prospectus, the Prospectus, or any amendment or supplement thereto during the period the Prospectus is required to be delivered in connection with the sale of the Units by the Underwriters or any dealer. For purposes of this Agreement, the words "amend," "amendment," "amended," "supplement" or "supplemented" with respect to the Registration Statement or the Prospectus shall mean amendments or supplements to the Registration Statement or the Prospectus, as the case may be. (b) No Stop Order; No Material Misstatements or Omissions. Neither the SEC nor any state or other jurisdiction or other regulatory body has issued, and neither is, to the knowledge of any of the Genesis Parties, threatening to issue, any stop order under the 1933 Act or other order suspending the effectiveness of the Registration Statement (as amended or supplemented) or preventing or suspending the use of the Preliminary Prospectus or the Prospectus or suspending the qualification or registration of the Units for offering or sale in any jurisdiction nor instituted or, to the knowledge of any of the Genesis Parties, threatened to institute proceedings for any such purpose. The Registration Statement, in the form in which it became effective and also in such form as it may be when any post-effective amendment thereto becomes effective, the Preliminary Prospectus and the Prospectus comply or will comply, as the case may be, in all material respects with the requirements of the 1933 Act and the 1933 Act Rules and Regulations. Neither the Registration Statement nor any amendment thereto, as of December 8, 2005, which is the date that any Preliminary Prospectus or Prospectus will first be used in connection with the sale (including, without limitation, contract of sale) of the Units to the public (the "FIRST SALE DATE"), and the applicable effective date, contained or will contain, as the case may be, any untrue statement of a material fact or omitted or will omit to state any material fact required to be stated therein or necessary to make the statements therein, not misleading; none of the Preliminary Prospectus, as of the First Sale Date, the Prospectus, as of its issue date, nor any supplement thereto, as of the date of such supplement, contained or will contain, as the case may be, any untrue statement of a material fact or omitted or will 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; provided, however, that the Partnership makes no representation or warranty as to information contained in or omitted from the Registration Statement, the Preliminary Prospectus or the Prospectus, or any such amendment or supplement, in reliance upon, and in conformity with, written information furnished to the Partnership relating to the Underwriters by or on behalf of the Underwriters expressly for use in the preparation thereof (as provided in Section 13 hereof).

Edwards & Sons, Inc. or by any Underwriter through A.G. Edwards & Sons, Inc., expressly for use in the preparation thereof (as provided in Section 13 hereof). (b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Genesis Parties from and against any losses, damages or liabilities to which the Genesis Parties may become subject, under the 1933 Act or otherwise, insofar as such losses, damages or liabilities (or actions or claims 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 or in any amendment or supplement thereto or any 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 (ii) any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Prospectus or Prospectus or in any amendment or supplement thereto or any omission or alleged omission to state therein a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Preliminary Prospectus, the Prospectus or any such amendment or supplement, in reliance upon and in conformity with written information relating to the Underwriters furnished to the Partnership by A.G.

Edwards & Sons, Inc., expressly for use in the preparation thereof (as provided in Section 13 hereof), and will reimburse the Genesis Parties for any legal or other expenses incurred by the Genesis Parties in connection with investigating or defending any such action or claim as such expenses are incurred (including such losses, damages, liabilities or expenses to the extent of the aggregate amount paid in settlement of any such action or claim, provided that (subject to Section 7(c) hereof) any such settlement is effected with the written consent of the Underwriters). (c) Promptly after receipt by an indemnified party under Section 7(a) or 7(b) hereof of notice of any claim or the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an indemnifying party under Section 7(a) or 7(b) hereof, notify each such indemnifying party in writing of the claim or action, but the failure so to notify such indemnifying party shall not relieve such indemnifying party from any liability except to the extent that it has been prejudiced in any material respect by such failure or from any liability that 22 it may have to any such indemnified party otherwise than under Section 7(a) or 7(b) hereof. In case any such any claim or action shall be brought against any such indemnified party and it shall notify each indemnifying party thereof, each such indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party under Section 7(a) or 7(b) hereof similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of such indemnified party, be counsel to such indemnifying party), and, after notice from such indemnifying party to such indemnified party of its election so to assume the defense thereof, such indemnifying party shall not be liable to such indemnified party under Section 7(a) or 7(b) hereof for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. The indemnified party shall have the right to employ its own counsel in any such action, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the employment of counsel by such indemnified party at the expense of the indemnifying party has been authorized by the indemnifying party, (ii) the indemnified party shall have been advised by such counsel that there may be a conflict of interest between the indemnifying party and the indemnified party in the conduct of the defense, or certain aspects of the defense, of such action (in which case the indemnifying party shall not have the right to direct the defense of such action with respect to those matters or aspects of the defense on which a conflict exists or may exist on behalf of the indemnified party) or (iii) the indemnifying party shall not in fact have employed counsel reasonably satisfactory to such indemnified party to assume the defense of such action, in any of which events such fees and expenses to the extent applicable shall be borne, and shall be paid as incurred, by the indemnifying party. If at any time such indemnified party shall have requested such indemnifying party under Section 7(a) or 7(b) hereof to reimburse such indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(a) or 7(b) hereof effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of such request for reimbursement, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 45 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request for reimbursement prior to the date of such settlement. No such indemnifying party shall, without the written consent of such indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not such indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of such indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any such indemnified party. In no event shall such indemnifying parties be liable for the fees and expenses of more than one counsel, including any local counsel, for all such indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. 23 (d) If the indemnification provided for in this Section 7 is unavailable to or insufficient to indemnify or hold harmless an indemnified party under Section 7(a) or 7(b) hereof in respect of any losses, damages or liabilities (or actions or claims in respect thereof) referred to therein, then each indemnifying party under Section 7(a) or 7(b) hereof shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages or liabilities (or actions or claims in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Genesis Parties, on the one hand, and the Underwriters, on the other hand, from the offering of the Units. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under Section 7(c) hereof and such indemnifying party was prejudiced in a material respect by such failure, then each such indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault, as applicable, of the Genesis Parties, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions that resulted in such losses, damages or liabilities (or actions or claims in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by, as applicable, the Genesis Parties, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion as the total net proceeds from the offering of the Units provided for in this Agreement (before deducting expenses) received by the Partnership bear to the total underwriting discounts and commissions received by the Underwriters. The relative fault, as applicable, of the Genesis Parties, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Genesis Parties, on the one hand, or the Underwriters, on the other hand, and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Genesis Parties and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to above in this Section 7(d). The amount paid or payable by such an indemnified party as a result of the losses, damages or liabilities (or actions or claims in respect thereof) referred to above in this Section 7(d) shall be deemed to include any legal or other expenses incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters in this Section 7(d) to contribute are several in proportion to their respective underwriting obligations with respect to the Units and not joint. 24 (e) The obligations of the Genesis Parties under this Section 7 shall be in addition to any liability that the Genesis Parties may otherwise have and shall extend, upon the same terms and conditions, to each officer, director, employee, agent or other representative and to each person, if any, who controls any Underwriter within the meaning of the 1933 Act; and the obligations of the Underwriters under this Section 7 shall be in addition to any liability that the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Partnership and the General Partner who signed the Registration Statement and to each person, if any, who controls the Genesis Parties within the meaning of the 1933 Act. 8. REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY. The respective representations, warranties, agreements and statements of the Genesis Parties and the Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain operative and in full force and effect regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, the Genesis Parties or any of their officers, directors or any controlling persons and shall survive delivery of and payment for the Units hereunder. 9. SUBSTITUTION OF UNDERWRITERS. (a) If any Underwriter shall default in its obligation to purchase the Units which it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for themselves or another party or other parties to purchase such Units on the terms contained herein. If within thirty-six hours after such default by any Underwriter the non-defaulting Underwriters do not arrange for the purchase of such Units, then the Partnership shall be entitled to a further period of thirty-six hours within which to procure another party or parties reasonably satisfactory to the non-defaulting Underwriters to purchase such Units on such terms. In the event that, within the respective prescribed periods, the non-defaulting Underwriters notify the Partnership that they have so arranged for the purchase of such Units, or the Partnership notifies the non-defaulting Underwriters that it has so arranged for the purchase of such Units, the non-defaulting Underwriters or the Partnership shall have the right to postpone the Closing Date for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Partnership agrees to file promptly any amendments to the Registration Statement or the Prospectus which in the opinion of the non-defaulting Underwriters may thereby be made necessary. The term "UNDERWRITER" as used in this Agreement shall include any persons substituted under this Section 9 with like effect as if such person had originally been a party to this Agreement with respect to such Units. (b) If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters made as provided in subsection (a) above, the aggregate number of Units which remains unpurchased does not exceed one-eleventh of the total Units to be sold on the Closing Date, then the Partnership shall have the right to require each non-defaulting Underwriter to purchase the Units which such Underwriter agreed to purchase hereunder and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Units which such Underwriter agreed to purchase hereunder) of the Units of such defaulting Underwriter or Underwriters for which such arrangements have not 25 been made; provided that nothing herein shall relieve a defaulting Underwriter from liability for its default. (c) If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters made by the non-defaulting Underwriters and the Partnership as provided in subsection (a) above, the number of Units which remains unpurchased exceeds one-eleventh of the total Units to be sold on the Closing Date, or if the Partnership shall not exercise the right described in subsection (b) above to require the non-defaulting Underwriters to purchase Units of the defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Option Closing Date, the obligations of the Underwriters to purchase and of the Partnership to sell the Option Units) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Genesis Parties except for the expenses to be borne by the Partnership and the Underwriters as provided in Section 11 hereof and the indemnity and contribution agreements in Section 7 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default. 10. TERMINATION. (a) This Agreement may be terminated by the Underwriters at any time at or prior to the Closing Date by notice to the Partnership if any condition specified in Section 6 hereof shall not have been satisfied on or prior to the Closing Date. Any such termination shall be without liability of any party to any other party except as provided in Sections 7 and 11 hereof. (b) This Agreement also may be terminated by the Underwriters, by notice to the Partnership, as to any obligation of the Underwriters to purchase the Option Units, if any condition specified in Section 6 hereof shall not have been satisfied at or prior to the Option Closing Date or as provided in Section 9 of this Agreement. If the Underwriters terminate this Agreement as provided in Sections 10(a) or 10(b), they shall notify the Partnership by telephone or telegram, confirmed by letter. 11. COSTS AND EXPENSES. The Partnership will bear and pay the costs and expenses incident to the registration of the Units and public offering thereof, including, without limitation, (a) all expenses (including transfer taxes) incurred in connection with the delivery to the several Underwriters of the Units, the filing fees of the SEC, the fees and expenses of the Partnership's counsel and accountants, (b) the preparation, printing, filing, delivery and shipping of the Registration Statement, the Preliminary Prospectus, the Prospectus and any amendments or supplements thereto and the printing, delivery and shipping of this Agreement and other underwriting documents, including the Agreement Among Underwriters, the Selected Dealer Agreement, Underwriters' Questionnaires and Powers of Attorney and Blue Sky Memoranda, and any instruments or documents related to any of the foregoing, (c) the furnishing of copies of such documents to the Underwriters, (d) the registration or qualification of the Units for offering and sale under the securities laws of the various states and other jurisdictions, including the fees and disbursements of counsel to the Underwriters relating to such registration or qualification and in connection with preparing any Blue Sky Memoranda or related analysis, (e) the filing fees of the NASD (if any) and fees and disbursements of counsel to the Underwriters relating to any review of the offering by the NASD, (f) all printing and engraving costs related to preparation of 26 the certificates for the Units, including transfer agent and registrar fees, (g) all fees and expenses relating to the authorization of the Units for trading on the American Stock Exchange; (h) all travel expenses, including air fare and accommodation expenses, of representatives of the Partnership in connection with the offering of the Units, and (i) all of the other costs and expenses incident to the performance by the Partnership of the registration and offering of the Units; provided, that (except as otherwise provided in this Section 11) the Underwriters will bear and pay all of their own costs and expenses, including the fees and expenses of the Underwriters' counsel, the Underwriters' transportation expenses and any advertising costs and expenses incurred by the Underwriters incident to the public offering of the Units. If this Agreement is terminated by the Underwriters in accordance with the provisions of Section 10(a) (other than pursuant to Section 6(h)(i), (iii), (iv) or (v)), the Partnership shall reimburse the Underwriters for all of their reasonable out-of-pocket expenses, including the reasonable fees and disbursements of counsel to the Underwriters. 12.

COUNTERPARTS.

A-1 EXHIBIT B OPINION OF AKIN GUMP STRAUSS HAUER & FELD LLP 1. Formation and Due Qualification. The General Partner is validly existing as a corporation and is in good standing under the laws of the State of Delaware with all corporate power and authority necessary to own or lease, as the case may be, its properties, to conduct its business and to act as a general partner of the Partnership, in each case in all material respects as described in the Prospectus. The General Partner is duly registered or qualified to do business as a foreign corporation and, based solely on the various certificates from the applicable public officials, is in good standing as a foreign corporation or as a limited partnership in each jurisdiction set forth under its name on Schedule III to this Agreement. Each of the Partnership Entities is validly existing as a partnership and is in good standing under the laws of the State of Delaware with all partnership power and authority necessary to own or lease, as the case may be, its properties and to conduct its business, in each case in all material respects as described in the Prospectus. Each of the Partnership Entities is duly registered or qualified to do business as a foreign partnership and, based solely on the various certificates from the applicable public officials, is in good standing as a foreign partnership in each jurisdiction set forth under its name on Schedule III to this Agreement. 2. Ownership of the General Partner Interest in the Partnership. The General Partner is the sole general partner of (i) the Partnership and owns (of record) a 2.0% general partner interest in the Partnership, (ii) the Operating Partnership and owns (of record) a 0.01% general partner interest in the Operating Partnership and (iii) each Subsidiary, but owns no economic interest therein. Such general partner interests have been duly authorized and validly issued to the General Partner in accordance with the Partnership Agreement and the Operating Partnership's partnership agreement, and the General Partner owns such general partner interest, free and clear of all liens, encumbrances, security interests, charges or claims (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the General Partner as debtor is on file as of a recent date in the office of the Secretary of State of the State of Delaware or (ii) otherwise known to such counsel, other than those (A) created under the Delaware LP Act, (B) created in connection with the Credit Facility, (C) created by the Partnership Agreement or the Operating Partnership's partnership agreement or (D) as disclosed in the Prospectus. 3. Limited Partner Interests Outstanding. As of the date hereof, the issued and outstanding limited partner interests of the Partnership (prior to the issuances of any Units pursuant to this Agreement or to the General Partner on the date hereof) consist of 9,313,811 Common Units and the Incentive Distribution Rights. All outstanding Common Units and the Incentive Distribution Rights and, in each case, the limited partner interests represented thereby have been duly authorized and validly issued in accordance with the Partnership Agreement, and are fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303 and 607 of the Delaware LP Act). B-1 4. Valid Issuance of the Units. The Units to be issued and sold to the Underwriters by the Partnership pursuant to this Agreement and the limited partner interests represented thereby have been duly authorized in accordance with the Partnership Agreement and, when issued and delivered to the Underwriters against payment therefor in accordance with the terms of this Agreement, will be validly issued, fully paid (to the extent required under the Partnership Agreement) and nonassessable (except as such nonassessability may be affected by Sections 17-303 and 17-607 of the Delaware LP Act). 5. Ownership of the Subsidiaries. The Partnership, directly or indirectly, owns (of record) (i) 100% of the limited partner interests in each of the Subsidiaries and (ii) 50% of the partnership interests in T&P Syngas; such limited partner interests and partnership interest have been duly authorized and validly issued in accordance with the partnership agreements of the respective Subsidiaries and T&P Syngas, respectively, and are fully paid (to the extent required under their respective limited partnership agreement) and non-assessable (except, with respect to those Subsidiaries that are limited partnerships, as such nonassessability may be affected by Sections 17-303 and 17-607 of the Delaware LP Act and, with respect to T&P Syngas, as the non-assessability of the partnership interests in T&P Syngas may be affected by the partnership agreement of T&P Syngas or the Delaware Revised Uniform Partnership Act), in each case, free and clear of all liens, encumbrances, security interests, charges or claims (i) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the Partnership or any Subsidiary as debtor is on file as of a recent date in the office of the Secretary of State of the State of Delaware or (ii) otherwise known to such counsel other than those (A) created under the Delaware LP Act, (B) created in connection with the Credit Facility, (C) created the partnership agreements or the constituent documents of the Subsidiaries and T&P Syngas, (D) created by the Partnership Agreement or (E) as disclosed in the Prospectus. 6. No Preemptive Rights, Registration Rights or Options. Except as described in the Prospectus or, in the case of transfer restrictions, options to purchase, other rights to subscribe or to purchase, voting restrictions and preemptive rights, created by the constituent documents of each Partnership Entity, there are no options, warrants, preemptive rights or other rights to subscribe for or to purchase, nor any restriction upon the voting or transfer of, any partnership interests in any Partnership Entity pursuant to any partnership agreement or other constituent document of any Partnership Entity or any other agreement or instrument listed as an exhibit to the Registration Statement or to any document filed by the Partnership with the SEC pursuant to the 1934 Act after December 31, 2004 (the "SEC Documents"). To the knowledge of such counsel, neither the filing of the Registration Statement nor the offering or sale of the Units as contemplated by this Agreement gives rise to any rights for or relating to the registration of any Units or other securities of any Partnership Entity other than as described in the Prospectus or as provided in the Partnership Agreement. 7. Authority and Authorization. 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 this Agreement and the Partnership Agreement. 8. Due Authorization, Execution and Delivery of Agreement. This Agreement has been duly authorized, executed and delivered by each of the Genesis Parties. B-2 9. Enforceability of Partnership Entity Operative Agreements. (i) The Partnership Agreement has been duly authorized, executed and delivered by the General Partner and is a valid and legally binding agreement of the General Partner, enforceable against the General Partner in accordance with its terms; provided, however, that the enforceability of each such agreement is subject to (a) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors' rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (b) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing. 10. No Conflicts. None of the offering, issuance and sale by the Partnership of the Units, the execution, delivery and performance of this Agreement by the Genesis Parties or the performance of the actions required to be taken by the Genesis Parties pursuant to this Agreement conflicts or will conflict with or constitutes or will constitute a breach or violation of or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under, or 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 (other than those created in connection with the Credit Facility) pursuant to, (i) the partnership agreement or other constituent document of any of the Partnership Entities, (ii) any agreement or other instrument filed as an exhibit to the Registration Statement or the SEC Documents, (iii) the Delaware LP Act, the Delaware General Corporation Law (the "DGCL"), the laws of the State of Texas or federal law or (iv) any order, judgment, decree or injunction of any court or governmental agency or body known to such counsel directed to any of the Partnership Entities or any of their properties in a proceeding to which any of them or their property is a party, which conflict, breach, violation, default, lien, charge or encumbrance, in the case of clauses (ii), (iii) or (iv), would in our judgment reasonably be expected to have a Material Adverse Effect or a material adverse effect on the ability of the Genesis Parties to consummate the transactions provided for in this Agreement; provided, however, that no opinion is expressed pursuant to this paragraph with respect to federal or state securities laws and other anti-fraud laws. 11. No Consents. No permit, consent, approval, authorization, order, registration, filing or qualification ("CONSENT") under the Delaware LP Act, the DGCL, Texas law or federal law is required in connection with the offering, issuance and sale by the Partnership of the Units, the execution, delivery and performance of this Agreement by the Partnership or the performance of the actions required to be taken by the Genesis Parties pursuant to this Agreement, other than (i) such consents required under state securities or "Blue Sky" laws or (ii) such consents that have been obtained or made. 12. Accuracy of Statements. The statements set forth in the Prospectus under the captions "Price Range of Common Units and Distributions," "Business--Credit Facility," "Description of our Equity Securities," "Cash Distribution Policy," and "Description of Our Partnership Agreement," insofar as they summarize any agreement, statute or regulation or refer to statements of law or legal conclusions, are accurate and fair summaries in all material respects; and the Common Units (including the Units) and the Incentive Distribution Rights conform in all material respects to the descriptions thereof contained in the Prospectus under the captions "Price B-3 Range of Common Units and Distributions," "Description of Our Equity Securities," "Cash Distribution Policy," and "Description of Our Partnership Agreement." 13. Tax Opinion. The opinion of Akin Gump Strauss Hauer & Feld LLP that is filed as Exhibit 8.1 to the Registration Statement is confirmed, and the Underwriters may rely upon such opinion as if it were addressed to them. 14. Effectiveness of Registration Statement. The Registration Statement was declared effective under the 1933 Act on September 1, 2005; to the knowledge of such counsel, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Prospectus pursuant to Rule 424(b) has been made in the manner and within the time period required by such Rule. 15.
