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

8. Indemnification and Contribution.

(a) The Partnership Parties, jointly and severally, shall indemnify and hold harmless each Underwriter, its directors, officers and employees, each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act and any affiliates or selling agents of such Underwriter who have, or who are alleged to have, participated in the distribution of the Securities as Underwriters (such affiliates or selling agents being referred to herein as “Participating Affiliates”), from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Securities) to which such Underwriter, directors, officers, employees, controlling persons or Participating Affiliates may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Pricing Disclosure Package, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus, or in any amendment or supplement thereto, (B) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) used or referred to by any Underwriter, or (C) any “road show” (as defined in Rule 433 of the Rules and Regulations) not constituting an Issuer Free Writing Prospectus (a “Non-Prospectus Road Show”), (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Pricing Disclosure Package, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or in any Permitted Issuer Information, any Non-Prospectus Road Show or any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of the Registration Statement) or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading (in the case of any Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or any Non-Prospectus Road Show) or (iii) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Securities or the offering contemplated hereby, and that is included as part of or referred to in any loss, claim, damage, liability or action arising out of or based upon matters covered by clause (i) or (ii) above (provided that the Partnership Parties shall not be liable under this clause (iii) to the extent that it is determined in a final judgment by a court of competent

jurisdiction that such loss, claim, damage, liability or action resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct), and shall reimburse each such Underwriter and each such director, officer, employee, controlling person or Participating Affiliate promptly upon demand for any legal or other expenses reasonably incurred by such Underwriter, director, officer, employee, controlling person or Participating Affiliate in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Partnership Parties shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Pricing Disclosure Package, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto, or in any Permitted Issuer Information, or any Non-Prospectus Road Show, in reliance upon and in conformity with written information concerning any Underwriter furnished to the Partnership through the Representatives by or on behalf of such Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 8(e) hereof. The foregoing indemnity agreement is in addition to any liability which the Partnership Parties may otherwise have to any Underwriter or to any director, officer, employee, controlling person or Participating Affiliate of such Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless each Partnership Party, its directors, officers, managers who are natural persons and employees and each person, if any, who controls such Partnership Party within the meaning of Section 15 of the Securities Act from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which such Partnership Party or any such director, officer, employee, manager who is a natural person or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Pricing Disclosure Package, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or in any Non-Prospectus Road Show, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Pricing Disclosure Package, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or in any Non-Prospectus Road Show, any material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any Preliminary Prospectus, the Pricing Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus or any Non-Prospectus Road Show, in the light of the circumstances under which any such statements were made), but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Partnership through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 8(e) hereof. The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to any Partnership Party or any director, officer, employee, manager who is a natural person or controlling person of such Partnership Party.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under this Section 8, except to the extent it has been materially prejudiced by such failure; and provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and the indemnified party shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes to assume, jointly with any other similarly notified indemnifying party, the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of the indemnifying party’s election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the Representatives shall have the right to employ counsel to represent jointly the Representatives and those other Underwriters and their respective directors, officers, employees, controlling persons and Participating Affiliates who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the Partnership Parties under this Section 8 if (i) the Partnership Parties and the Underwriters shall have so mutually agreed; (ii) the Partnership Parties have failed within a reasonable time to retain counsel reasonably satisfactory to the Underwriters; (iii) the Underwriters and their respective directors, officers, employees, controlling persons and Participating Affiliates shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the Partnership Parties; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Underwriters or their respective directors, officers, employees, controlling persons or Participating Affiliates, on the one hand, and the Partnership Parties or their respective directors, officer, employees, managers who are natural persons or controlling persons, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the Partnership Parties. No indemnifying party shall (X) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld) settle, or compromise or consent to the entry of any judgment with respect to, any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include any findings of fact or admissions of fault or culpability

as to the indemnified party or (Y) be liable for any settlement of any such claim, action, suit or proceedings effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such claim, action, suit or proceeding, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) hereof in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Partnership Parties, on the one hand, and the Underwriters, on the other, from the offering of the Securities or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership Parties, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Partnership Parties, on the one hand, and the Underwriters, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Securities purchased under this Agreement (before deducting expenses) received by the Issuers, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Securities purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand, bear to the total gross proceeds from the offering of the Securities purchased under this Agreement. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Partnership Parties or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Partnership Parties and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating, defending or preparing to defend any such action or claim. Notwithstanding the provisions of this Section 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Securities underwritten by it exceeds the amount of any damages that such Underwriter has otherwise paid or become liable to pay by reason of any untrue or alleged untrue

statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and the Partnership Parties acknowledge and agree that the table of the names of, and the respective principal amounts of the Securities to be purchased by, each of the Underwriters, the public offering price and the statements regarding delivery of the Securities by the Underwriters set forth on the cover page of, and the concession and reallowance figures and the paragraph relating to stabilization by the Underwriters appearing under the caption “Underwriting” in, the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning the Underwriters furnished in writing to the Issuers by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto.

9. Defaulting Underwriters. If, on the Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriter(s) shall be obligated to purchase the Securities that the defaulting Underwriter(s) agreed but failed to purchase on the Delivery Date in the respective proportions which the principal amount of Securities set forth opposite the name of each remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total principal amount of the Securities set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that the remaining non-defaulting Underwriter(s) shall not be obligated to purchase any of the Securities on the Delivery Date if the total principal amount of Securities that the defaulting Underwriter(s) agreed but failed to purchase on the Delivery Date exceeds 9.09% of the aggregate principal amount of Securities, and any remaining non-defaulting Underwriter shall not be obligated to purchase more than 110% of the principal amount of Securities that it agreed to purchase on the Delivery Date pursuant to the terms of Section 2 hereof. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriter(s), 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, the total aggregate principal amount of Securities. If the remaining non-defaulting Underwriter(s) or other underwriters satisfactory to the Underwriters do not elect to purchase the Securities that the defaulting Underwriter(s) agreed but failed to purchase on the Delivery Date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Partnership Parties, except that the Partnership Parties will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 11 hereof. 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 1 hereto that, pursuant to this Section 9, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to any Partnership Party for damages caused by its default. If other Underwriters are

obligated or agree to purchase the Securities of a defaulting or withdrawing Underwriter, either the Representatives or the Issuers may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Partnership Parties or counsel for the Underwriters may be necessary in the Registration Statement, any Preliminary Prospectus, the Prospectus or in any other document or arrangement.

10. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Issuers prior to delivery of and payment for the Securities if, prior to that time, any of the events described in Section 7(j), Section 7(k) and Section 7(l) hereof shall have occurred or if the Underwriters shall decline to purchase the Securities for any reason permitted under this Agreement.

11. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated (i) because any condition of the Underwriters’ obligations set forth in Section 7 hereof (other than Sections 7(l)(i), (iii), (iv) or (v)) is not satisfied or (ii) because of any refusal, inability or failure on the part of any Partnership Party to perform any agreement herein or comply with any provision hereof other than by reason of a default by any Underwriter, the Partnership Parties will reimburse the Underwriters on demand for all reasonable out-of-pocket expenses (including fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

12. Research Analyst Independence. The Partnership Parties acknowledge that (a) 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 (b) the Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Issuers, the value of the Securities and/or the offering that differ from the views of their respective investment banking divisions. The Partnership Parties hereby waive and release, to the fullest extent permitted by law, any claims that the Partnership 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 Parties or their affiliates by any Underwriter’s investment banking division. The Partnership Parties acknowledge 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 are the subject of the transactions contemplated by this Agreement.

13. No Fiduciary Duty. The Partnership Parties acknowledge and agree that in connection with this offering, sale of the Securities or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (a) no fiduciary or agency relationship between any Partnership Party, any affiliate of a Partnership Party or any other person, on the one hand, and the Underwriters, on the other, exists; (b) the Underwriters are not acting as advisors, expert or otherwise, to the Partnership Parties or any of their affiliates, including, without limitation, with respect to the determination of the public offering price of the Securities, and such relationship

between the Partnership Parties or any of their affiliates, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (c) any duties and obligations that the Underwriters may have to the Partnership Parties or their affiliates shall be limited to those duties and obligations specifically stated herein; and (d) the Underwriters and their respective affiliates may have interests that differ from those of the Partnership Parties and their affiliates. Each Partnership Party hereby waives, on its own behalf and on behalf of its affiliates, any claims that the Partnership Parties or any of their affiliates may have against any Underwriter with respect to any breach or alleged breach of fiduciary duty in connection with this offering.

14. Notices, Etc. 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 Barclays Capital Inc., 000 Xxxxxxx Xxxxxx, Xxx Xxxx, Xxx Xxxx 00000, Attn: Syndicate Registration (Fax: (000) 000-0000); and X.X.

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Partnership shall be entitled to act and rely upon any request, consent, notice or agreement given or made by the Representatives on behalf of the Underwriters.

15. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Partnership Parties and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (a) the representations, warranties, indemnities and agreements of the Partnership Parties contained in this Agreement shall also be deemed to be for the benefit of the directors, officers and employees of the Underwriters and each person or persons, if any, who control any Underwriter within the meaning of Section 15 of the Securities Act and (b) the indemnity agreement of the Underwriters contained in Section 8(b) hereof shall be deemed to be for the benefit of the directors of BGL, the officers of BGL who have signed the Registration Statement and any person controlling BGL within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 15, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. Notwithstanding anything in this Agreement to the contrary, all liabilities and obligations of the Partnership Parties hereunder shall be non-recourse against Loews or any limited partner, stockholder, member, officer, manager, director or employee of any of the Partnership Parties who is a natural person. In that connection, neither Loews nor any such limited partner, stockholder, member, officer, manager, director or employee who is a natural person shall be bound by this Agreement, or be obligated by virtue of this Agreement or the obligations of any party created hereunder to (y) provide funds to any of the Partnership Parties, whether by contributions to capital, loans, returns of monies,

securities or other property, or (z) assume any liabilities of any of the Partnership Parties.

In rendering such opinion, such counsel may state that its opinion is limited to matters governed by the federal laws of the United States of America, the laws of the State of New York, the Delaware LP Act and the Delaware LLC Act.

(b) the Prospectus, as of its date and as of the Delivery Date, contained or contains any untrue statement of a material fact or omitted or omits 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

“applicable law” means those laws, rules and regulations that, in such counsel’s experience, are normally applicable to transactions of the type contemplated by the Debt Documents, without such counsel’s having made any special investigation as to the applicability of any specific law, rule or regulation, and that are not the subject of a specific opinion herein referring expressly to a particular law or laws; provided, however, that such references do not include any municipal or other local laws, rules or regulations, or any antifraud, environmental, labor, state securities or blue sky, tax, insurance or antitrust, laws, rules or regulations, the Natural Gas Act, as amended, or the rules and regulations promulgated thereunder by the Federal Energy Regulatory Commission.
