(a)
Subsections (a) and (b) of Item 5 are hereby amended by deleting the text thereof in their entirety and replacing them with the following:

(a) After giving effect to the closing of the sale of common units to the underwriters referenced in Item 6 below, and assuming that the underwriters do not exercise their option to purchase additional common units, BPHC will be the record and beneficial owner of 104,219,466 Common Units, which in the aggregate represents approximately 61.4% of the outstanding Common Units. If the underwriters exercise their option to purchase additional common units in full, BPHC will be the record and beneficial owner of 102,719,466 Common Units, which in the aggregate represents approximately 60.5% of the outstanding Common Units. BPHC also holds 22,866,667 Class B Units which are convertible into equal numbers of Common Units.

By virtue of its ownership of all the outstanding common stock of BPHC, Loews may be deemed to possess indirect beneficial ownership of the Common Units and Class B Units beneficially owned by BPHC.

The filing of this Schedule 13D shall not be construed as an admission by any Reporting Person that, for the purpose of Section 13(d) or 13(g) of the Act, such Reporting Person is the beneficial owner of any securities covered by this Schedule 13D other than securities owned of record by such Reporting Person.

Except as indicated in this Item 5 or as set forth below, neither the Reporting Persons nor, to the best knowledge of the Reporting Persons, any of the persons named in Schedule A to this Schedule 13D owns beneficially, or has any right to acquire, directly or indirectly, any Common Units. Certain of the persons named in Schedule A to this Schedule 13D beneficially own Common Units in the amounts set forth next to their names in Schedule A.

 
(b)
After giving effect to the closing of the sale of common units to the underwriters referenced in Item 6 below, and assuming that the underwriters do not exercise their option to purchase additional common units, BPHC will have the power to vote or direct the vote and the power to dispose of or direct the disposition of the 104,219,466 Common Units and 22,866,667 Class B Units beneficially owned by it. If the underwriters exercise their option to purchase additional common units in full, will have the power to vote or direct the vote and the power to dispose of or direct the disposition of the 102,719,466 beneficially owned by it.

By virtue of its ownership of all the outstanding common stock of BPHC, Loews may be deemed to possess indirect beneficial ownership of the Common Units and Class B Units beneficially owned by BPHC and may be deemed to possess the power to vote or direct the vote and the power to dispose of or direct the disposition of the Common Units and Class B Units beneficially owned by BPHC.

The filing of this Schedule 13D shall not be construed as an admission by any Reporting Person that, for the purpose of Section 13(d) or 13(g) of the Act, such Reporting Person is the beneficial owner of any securities covered by this Schedule 13D other than securities owned of record by such Reporting Person.

Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
  
 
 
Item 6 is hereby amended by deleting the text thereof in its entirety and replacing it with the following:

Issuer Partnership Agreement

Subject to the terms and conditions of the Third Amended and Restated Agreement of Limited Partnership of the Issuer, as amended (the “Issuer Partnership Agreement”), the general partner of the Issuer and its affiliates have the right to cause the Issuer to register for resale under the Securities Act of 1933 and applicable state securities laws any limited partner units that they hold. The Issuer is obligated to pay all expenses incidental to the registration, excluding underwriting discounts and commissions. Pursuant to the terms of the Issuer Partnership Agreement, each Class B Unit will be convertible into common units on a one-for-one basis upon demand by the holder at any time after June 30, 2013.

The Issuer Partnership Agreement additionally contains various provisions with respect to the units governing, among other matters, distributions, transfers and allocations of profits and losses to the partners.

Unit Purchase Agreement.

On June 23, 2009, the Issuer entered into a Purchase Agreement (the “Unit Purchase Agreement”) with BPHC to sell 6,684,857 Common Units. The transactions contemplated by the Unit Purchase Agreement closed on June 26, 2009.

Registration Rights Agreement

In connection with the Unit Purchase Agreement, the Issuer and BPHC amended and restated the registration rights agreement (as so amended and restated, the “Registration Rights Agreement”) dated June 17, 2008, which had previously been amended and restated on November 4, 2008. Pursuant to the Registration Rights Agreement, the Issuer is required to file a shelf registration statement to register, upon request of BPHC, a number of Common Units equal to the sum of (1) the aggregate number of Common Units issuable upon conversion of the Class B Units and (2) 27,869,466. The Registration Rights Agreement also includes provisions dealing with holdback agreements, indemnification and contribution, and allocation of expenses. In addition, pursuant to the terms of the Registration Rights Agreement, with respect to the first 27,869,466 units covered under the Registration Rights Agreement and sold to the public in one or more underwritten offerings, the Partnership shall reimburse selling holders for up to $0.914 per common unit for selling expenses incurred in connection with the sale of such units. These registration rights are transferable to affiliates of BPHC and, in certain circumstances, to third parties.

Underwriting Agreement

On February 18, 2010, BPHC entered into an underwriting agreement with Barclays Capital Inc., Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. Incorporated, UBS Securities LLC and Wells Fargo Securities, LLC, as representatives of the underwriters named therein. Under the terms of the underwriting agreement, which the Issuer has filed as an exhibit to a current report on Form 8-K and we incorporate by reference in this Schedule 13D, BPHC agreed to sell the underwriters 10,000,000 common units, for $28.93 per common unit. BPHC has granted the underwriters an option exercisable for 30 days after February 18, 2010 to purchase, from time to time, in whole or in part, up to an aggregate of 1,500,000 additional common units at same price. In connection with the offering and sale of the common units, which closed on February 23, 2010, BPHC received proceeds, after deducting underwriting commissions and expenses and after giving effect to the reimbursement of a portion of the underwriting commissions by the Issuer pursuant to the Registration Rights Agreement, of $298.4 million.
