(aaa) The Units have been approved for listing on the New York Stock Exchange (the “NYSE”), subject only to official notice of issuance.

(bbb) Except for this Agreement, there are no contracts, agreements or understandings between the Partnership and any person that would give rise to a valid claim against the Partnership or any Underwriter for a brokerage commission, finder’s fee or other like payment in connection with the offering and sale of the Units contemplated by this Agreement.

(ccc) Each certificate signed by or on behalf of any Partnership Entity and delivered to the Underwriters or counsel for the Underwriters pursuant to this Agreement shall be deemed to be a representation and warranty by each such Partnership Entity to the Underwriters as to the matters covered thereby.

None of the Loews Entities has offered, or caused the Underwriters to offer, Common Units to any person pursuant to the Directed Unit Program with the specific intent to unlawfully influence (i) a customer or supplier of the Loews Entities to alter the customer’s or supplier’s level or type of business with the Loews Entities, or (ii) a trade journalist or

publication to write or publish favorable information about the Loews Entities or their respective products or businesses.

(a) On the basis of the representations and warranties contained in, and subject to the terms and conditions of, this Agreement, the Partnership agrees to sell 15,000,000 Firm Units to the several Underwriters, and each of the Underwriters, severally and not jointly, agrees to purchase the number of Firm Units set forth opposite such Underwriter’s name in Schedule 1 hereto.

(b) In addition, the Partnership grants to the Underwriters an option to purchase up to an additional 2,250,000 Option Units. Such option (the “Option”) is exercisable in the event that the Underwriters sell more than the number of Firm Units in the offering and is exercisable as provided in Section 4 hereof. Each Underwriter agrees, severally and not jointly, to purchase that number of Option Units (subject to such adjustments to eliminate fractional units as the Representatives may determine) that bears the same proportion to the total number of Option Units to be sold on any Delivery Date by the Partnership to the Underwriters pursuant to this Agreement as the number of Firm Units set forth opposite the name of such Underwriter in Schedule 1 hereto bears to 15,000,000 Firm Units.

(d) The Partnership shall not be obligated to deliver any of the Units to be delivered on any Delivery Date except upon payment for all the Units to be purchased on such Delivery Date as provided herein.

Time shall be of the essence, and delivery of the Firm Units at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder.

(b) The Option granted in Section 2 hereof will expire 30 days after the date of this Agreement; provided, however, that if such date falls on a day that is not a business day, the Option will expire on the next succeeding business day. The Option may be exercised in whole or in part from time to time by written notice to the Partnership by the Representatives. Such notice shall set forth the aggregate number of Option Units as to which the Option is being exercised, the names in which the Option Units are to be registered, the denominations in which the Option Units are to be issued and the date and time, as determined by the Representatives, when the Option Units are to be delivered; provided, however, that such date and time shall not be earlier than the First Delivery Date, earlier than the second business day after the date on which the Option shall have been exercised nor later than the fifth business day after the date on which the Option shall have been exercised. The date and time specified for delivery of any Option Units are sometimes referred to herein as a “Second Delivery Date,” and the First Delivery Date and any Second Delivery Date are sometimes each referred to herein as a “Delivery Date.”

(ii) No stop order suspending the effectiveness of the Registration Statement has been issued, and no proceedings for that purpose have been instituted or, to their knowledge, threatened; and

(iii) They have carefully examined the Registration Statement and the Prospectus and, in their opinion, (A) the Registration Statement, as of the Effective Time, and the Prospectus, as of its date and as of such Delivery Date, did not and do not contain any untrue statement of a material fact and did not and do not omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of the Prospectus, in the light of the circumstances under which such statements were made) and (B) since

the Effective Time, no event has occurred that should have been set forth in a supplement or amendment to the Registration Statement or the Prospectus that has not been so set forth.

(m) Since the date of the latest audited financial statements included in the Prospectus (exclusive of any amendment or supplement thereto after the date hereof), (i) no Partnership Entity shall have sustained any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, any labor dispute or any court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus, (ii) no Partnership Entity shall have become a party to or the subject of any litigation or court or governmental action, investigation, order or decree that is adverse to any Partnership Entity and (iii) there shall not have been any adverse change in the partners’ capital, members’ equity or short- or long-term debt of any Partnership Entity or any adverse change, or any development involving a prospective adverse change, in or affecting the condition (financial or otherwise), results of operations, securityholders’ equity, properties, management, business or prospects of any Partnership Entity, otherwise than as set forth or contemplated in the Prospectus, the effect of which, in any such case, is, in the judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or delivery of the Units being delivered on such Delivery Date on the terms and in the manner contemplated herein and in the Prospectus.

(n) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the NYSE or the American Stock Exchange or in the over-the-counter market, or trading in any securities of the Partnership or any other Loews Entity on any exchange or in the over-the-counter market, shall have been suspended or materially limited, the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by federal or state authorities, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States or (iv) a material adverse change in general economic, political or financial conditions, including, without limitation, changes resulting from terrorist activities or any other calamity or crisis after the date hereof or from the effect of international conditions on the financial markets in the United States, that would make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the public offering or delivery of the Units being delivered on such Delivery Date on the terms and in the manner contemplated herein and in the Prospectus.

(o) Subsequent to the execution and delivery of this Agreement, if any debt securities of any of the Partnership Entities are rated by any “nationally recognized statistical rating organization,” as such term is defined by the Commission for purposes of Rule 436(g)(2) of the Rules and Regulations, (i) no downgrading shall have occurred in the rating accorded such debt securities and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative

implications, its rating of any securities of any of the Partnership Entities; provided, however, that this paragraph (o) shall not apply to any downgrade contemplated by an existing notice of surveillance or review.

(p) The NYSE shall have approved the Units for listing, subject only to official notice of issuance.

(q) The Lock-Up Agreements between the Representatives and the securityholders, executive officers and directors of the Partnership Entities listed in Schedule 3 hereto shall have been delivered to the Representatives on or before the date hereof.

(r) The Representatives shall have received from the BPHC Parties such additional documents and certificates as the Representatives or counsel for the Underwriters may reasonably request.

(s) The Representatives shall have received evidence satisfactory to them that each of the Transactions (other than the offering of the Units), including the closing of the borrowings under the Credit Agreement, has occurred or will occur as of the First Delivery Date on substantially the terms described in the Prospectus.

All opinions, letters, documents, evidence and certificates mentioned above or elsewhere in this Agreement shall be in compliance with the provisions hereof only if they are in form and substance reasonably satisfactory to counsel for the Underwriters.

8. Indemnification and Contribution.

(a) The BPHC Parties, jointly and severally, shall indemnify and hold harmless each Underwriter, each of such Underwriter’s directors, officers, managers and employees and each person, if any, who controls such Underwriter 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 (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Units), to which such Underwriter, director, officer, manager, employee 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 (A) the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto (in the case of any Preliminary Prospectus or the Prospectus, in the light of the circumstances under which such statements were made), (B) any “blue sky” application or other document prepared or executed by the Partnership (or based upon any written information furnished by the Partnership for use therein) specifically for the purpose of qualifying any or all of the Units under the securities laws of any state or other jurisdiction (any such application, document or information, a “Blue Sky Application”) or (C) any materials or information provided to investors by, or with the written approval of, the Partnership in connection with the marketing of the offering of the Units (“Marketing Materials”), including any road show or investor presentations made to

investors by the Partnership (whether in person or electronically), (ii) the omission or alleged omission to state in the Registration Statement, any amendment or supplement thereto, any Blue Sky Application or any Marketing Materials any material fact required to be stated therein or necessary to make the statements therein not misleading, (iii) the omission or alleged omission to state in any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto any material fact necessary to make the statements therein, in the light of the circumstances under which such statements were made, not misleading or (iv) 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 Units 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 clauses (i), (ii) or (iii) above (provided that the BPHC Parties shall not be liable under this clause (iv) 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 act or failure to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct), and shall reimburse each such Underwriter, director, officer, manager, employee and controlling person promptly upon demand for any legal or other expenses reasonably incurred by such Underwriter, director, officer, manager, employee or controlling person 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 BPHC 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, alleged untrue statement, omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Prospectus, any amendment or supplement thereto in reliance upon and in conformity with written information concerning such 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 and provided further, that this paragraph (a) with respect to any Preliminary Prospectus shall not inure to the benefit of any Underwriter (or any person controlling such Underwriter) on account of any loss, claim, damage, liability or action arising from the sale of Units to any person by such Underwriter if such Underwriter failed to send or give a copy of the Prospectus, as the same may be amended or supplemented, to such person within the time required by the Securities Act and the Rules and Regulations, and the untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact in the Preliminary Prospectus was corrected in the Prospectus, unless such failure to deliver the Prospectus resulted from non-compliance by the Partnership with Sections 5(c) or 5(d) hereof. The foregoing indemnity agreement is in addition to any liability that the BPHC Parties may otherwise have to any Underwriter or to any director, officer, manager, employee or controlling person of such Underwriter.

(b) Each Underwriter shall, severally and not jointly, indemnify and hold harmless each BPHC Party, each of such BPHC Party’s directors, officers, managers and employees and each person, if any, who controls such BPHC 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 BPHC Party, director, officer, manager, employee 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 (A) the Registration Statement, any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto or (B) any Marketing Materials, (ii) the omission or alleged omission to state in the Registration Statement, any amendment or supplement thereto, or any Marketing Materials any material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) the omission or alleged omission to state in any Preliminary Prospectus, the Prospectus or any amendment or supplement thereto any material fact necessary to make the statements therein, in the light of the circumstances under which such statements were made, not misleading, but in each case only to the extent that the untrue statement, alleged untrue statement, 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 such Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 8(e) hereof, and shall reimburse each such BPHC Party, director, officer, manager, employee and controlling person for any legal or other expenses reasonably incurred by such BPHC Party, director, officer, manager, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred. The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to any BPHC Party or to any director, officer, manager, employee or controlling person of such BPHC 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 such claim or the commencement of such action; provided, however, that the failure to so 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 so 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, managers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Underwriters against the BPHC Parties under this Section 8 if (i) the BPHC Parties and the Underwriters shall have so mutually agreed; (ii) the BPHC Parties have failed within a reasonable time to

retain counsel reasonably satisfactory to the Underwriters; (iii) the Underwriters and their respective directors, officers, managers, employees and controlling persons 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 BPHC Parties; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Underwriters or their respective directors, officers, managers, employees or controlling persons, on the one hand, and the BPHC Parties or their respective directors, managers, officers, employees 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 such event the fees and expenses of such separate counsel shall be paid by the BPHC Parties. No indemnifying party shall (i) without the prior written consent of the indemnified parties, which consent shall not be unreasonably withheld, settle, 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 such indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each such 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 such indemnified party or (ii) be liable for any settlement of any such claim, action, suit or proceeding effected without its written consent, which consent shall not be unreasonably withheld; provided that if such claim, action, suit or proceeding be 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. Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to Section 8(f) hereof in respect of such action or proceeding, then in addition to such separate firm for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for Citigroup Global Markets Inc., the directors, officers, managers, employees and agents of Citigroup Global Markets Inc., and all persons, if any, who control Citigroup Global Markets Inc. within the meaning of either the Securities Act or the Exchange Act for the defense of any losses, claims, damages and liabilities arising out of the Directed Unit Program.

(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), 8(b) or 8(f) 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 BPHC Parties, on the one hand, and the Underwriters, on the other hand, from the offering of the Units 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 BPHC Parties, on the one hand, and the Underwriters, on the other hand, 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 BPHC Parties, on the one hand, and the Underwriters, on the other hand, with respect to the offering of the Units shall be deemed to be in the same proportion as the total net proceeds received by the Partnership from the offering of the Units purchased under this Agreement (before deducting expenses), 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 Units 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 of the offering of the Units under this Agreement, as set forth in the table on the cover page of the Prospectus. 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 BPHC Parties or the Underwriters, to the intent of the parties and to their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The BPHC 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 or 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 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 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 BPHC Parties acknowledge that the table of Underwriters on page [147], the second full paragraph under the heading “Commissions and Expenses” on page [147], the information under the heading “Offering Price Determination” on page [148], the first sentence under the heading “Stabilization, Short Positions and Penalty Bids” on page [149] and the information under the heading “Discretionary Sales” on page [150], in each case appearing under the caption “Underwriting” in the Prospectus, are correct and constitute the only information concerning such Underwriters furnished in writing to the Partnership by or on behalf of the Underwriters specifically for inclusion in the Registration Statement and the Prospectus.

(f) The BPHC Parties, jointly and severally, agree to indemnify and hold harmless Citigroup Global Markets Inc., the directors, officers, managers, employees and agents of Citigroup Global Markets Inc. and each person who controls Citigroup Global Markets Inc. within the meaning of either the Securities Act or the Exchange Act (the “Citigroup Entities”) from and against any and all losses, claims, damages and liabilities to which they may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim), insofar as such losses, claims damages or liabilities (or actions in respect thereof) (i) arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in any material prepared by or with the approval of any BPHC Party for distribution to Participants in the Directed Unit Program in connection with the Directed Unit Program 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 (in the case of the Prospectus or any Preliminary Prospectus, in the light of the circumstances under which such statements were made), (ii) are caused by the failure of any Participant to pay for and accept delivery of the securities that, immediately following the Effective Time of the Registration Statement, were subject to a properly confirmed agreement to purchase; or (iii) relate to or arise out of or in connection with the Directed Unit Program, except that this clause (iii) shall not apply to the extent that such loss, claim, damage or liability is finally judicially determined to have resulted primarily from the bad faith, gross negligence or willful misconduct of the Citigroup Entities.

9. Defaulting Underwriters. If, on any Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, each remaining non-defaulting Underwriter shall be obligated to purchase the Units that the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date in the proportion that the number of Firm Units set forth opposite the name of such remaining non-defaulting Underwriter in Schedule 1 hereto bears to the total number of Firm Units set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule 1 hereto; provided, however, that no remaining non-defaulting Underwriter shall be obligated to purchase any Units that the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date if the total number of such Units exceeds 9.09% of the total number of Units to be purchased on such Delivery Date, and no remaining non-defaulting Underwriter shall be obligated to purchase more than 110% of the number of Units that it agreed to purchase on such Delivery Date pursuant to the terms of Section 2 hereof. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but not the obligation, to purchase, in such proportion as may be agreed upon among them, all Units to be purchased on such Delivery Date. If the remaining non-defaulting Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the Units that the defaulting Underwriter or Underwriters agreed but failed to purchase on such Delivery Date, this Agreement (or, with respect to any Second Delivery Date, the obligation of the Underwriters to purchase, and of the Partnership to sell, the Option Units) shall terminate without liability on the part of any non-defaulting Underwriters or the BPHC Parties, except that the BPHC 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 who, pursuant to this Section 9, purchases Units that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the BPHC Parties for damages caused by its default. If other underwriters are obligated or agree to purchase the Units of a defaulting or withdrawing Underwriter, either the Representatives or the Partnership may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

10. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Partnership prior to delivery of and payment for the Firm Units if, prior to that time, any of the events described in Sections 7(m), 7(n) or 7(o) hereof shall have occurred or if the Underwriters shall decline to purchase the Units for any reason permitted under this Agreement.

11. Reimbursement of Underwriters’ Expenses. If the sale of the Units provided for herein is not consummated because any condition of the Underwriters’ obligations set forth in Section 7 hereof is not satisfied, because of any termination pursuant to Section 10 hereof or because of any refusal, inability or failure on the part of any BPHC Party to perform any agreement herein or comply with any provision hereof (including, without limitation, with respect to the Transactions) other than by reason of a default by any of the Underwriters, the BPHC Parties will reimburse the Underwriters severally through the Representatives 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 Units.

12. Research Independence. In addition, the BPHC Parties acknowledge that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold and make statements or investment recommendations and/or publish research reports with respect to the Partnership and/or the offering that differ from the views of its investment bankers. Each BPHC Party hereby waives and releases, on its own behalf and on behalf of Loews, to the fullest extent permitted by law, any claims that Loews or such BPHC Party 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 Loews or the BPHC Parties by such Underwriters’ investment banking divisions. The BPHC 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 Loews Entities.

13. No Fiduciary Duty. Notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters, each BPHC Party acknowledges and agrees that in

connection with the offering contemplated by this Agreement (the “Offering”): (i) there exists no fiduciary or agency relationship between any Loews Entity, on the one hand, and the Underwriters, on the other hand; (ii) the relationship between the Loews Entities, on the one hand, and the Underwriters, on the other, is entirely and solely commercial and based on arms-length negotiations, and the Underwriters are not acting as advisors, expert or otherwise, to any Loews Entity; (iii) notwithstanding anything in this Agreement to the contrary, the Underwriters may have financial interests in connection with the Offering in addition to the difference between the public offering price and the purchase price paid to the Partnership by the Underwriters for the Units, and the Underwriters have no obligation to disclose, or account to any Loews Entity for, any of such additional financial interests. Each BPHC Party hereby waives and releases, on its own behalf and on behalf of Loews, to the fullest extent permitted by law, any claims that Loews or such BPHC Party may have against the Underwriters with respect to any breach or alleged breach of fiduciary duty in connection with the Offering.
