On June 23, 2009, Boardwalk Pipeline Partners, LP (the "Partnership") entered into a Unit Purchase Agreement (the "Unit Purchase Agreement") with Boardwalk Pipelines Holding Corp. ("BPHC") to sell 6,684,857 common units representing limited partner interests in the Partnership (the "Units") to BPHC in a private placement (the "Private Placement"). The negotiated purchase price for the Units was $21.99 per unit, the closing price of the common units on the New York Stock Exchange on June 22, 2009, for an aggregate purchase price of approximately $147 million. The Private Placement was exempt from registration under the Securities Act of 1933, as amended, pursuant to Section 4(2) thereof because it did not involve a public offering. On June 26, 2009, the Partnership issued and sold the 6,684,857 common units to BPHC pursuant to the Unit Purchase Agreement. An additional $3 million was contributed to the Partnership on behalf of Boardwalk GP, LP, the Partnership's general partner (the "General Partner"), to maintain its 2% general partner interest. A copy of the Unit Purchase Agreement is filed as Exhibit 10.1 to this Form 8-K and is incorporated herein by reference. The description of the Unit Purchase Agreement in this report is a summary and is qualified in its entirety by the terms of the Unit Purchase Agreement.

After giving effect to the Private Placement, BPHC, a wholly-owned subsidiary of Loews Corporation, owns approximately 114.2 million of the Partnership's common units and all of the class B units. The General Partner is an indirect, wholly-owned subsidiary of BPHC and holds a 2.0% general partner interest in the Partnership and all of the Partnership's incentive distribution rights.

On June 26, 2009, in connection with the Unit Purchase Agreement, the Partnership entered into a Second Amended and Restated Registration Rights Agreement (the "Registration Rights Agreement") with BPHC, amending and restating the amended and restated registration rights agreement dated November 4, 2008. Pursuant to the Registration Rights Agreement, the Partnership is required to file a shelf registration statement to register the Units issued to BPHC upon request of BPHC. 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. A copy of the Registration Rights Agreement is filed as Exhibit 4.1 to this Form 8-K and is incorporated herein by reference. The description of the Registration Rights Agreement in this report is a summary and is qualified in its entirety by the terms of the Registration Rights Agreement.
