On May 1, 2009, Boardwalk Pipelines, LP (the "Borrower"), a wholly owned subsidiary of Boardwalk Pipeline Partners, LP, entered into an unsecured subordinated loan agreement (the "Subordinated Credit Agreement") for an aggregate principal amount of up to $200.0 million with Boardwalk Pipelines Holding Corp. ("BPHC"), an affiliate of the Borrower. The Borrower is entitled to borrow the loans available under the Subordinated Credit Agreement in minimum increments of $25,000,000 at any time during the one (1) year period after the closing of the Subordinated Credit Agreement. Loans under the Subordinated Credit Agreement will mature on the date six months after the later of (i) the Scheduled Maturity Date, as defined in the Amended and Restated Revolving Credit Agreement dated June 29, 2006 (as amended and as may be further amended replaced or refinanced from time to time, the "Senior Credit Agreement"), which is expected to mature on June 29, 2012; and (ii) if a Term Out Period (as defined in the Senior Credit Agreement) has become effective under the Senior Credit Agreement, the last day of the Term Out Period. Any amounts borrowed under the Subordinated Loan Agreement will bear interest at an annual rate of 8.0%. On May 4, 2009, the Borrower borrowed $100.0 million under the Subordinated Credit Agreement.

If an event of default occurs under the Subordinated Credit Agreement, BPHC may terminate the Subordinated Loan Commitment (as defined in the Subordinated Credit Agreement) and accelerate the maturity of all outstanding Subordinated Loans (as defined in the Subordinated Credit Agreement) as well as exercise other rights and remedies. Each of the following will be an event of default under the Subordinated Credit Agreement:

· failure to pay any principal, interest, fees, expenses or other amounts when due;

· failure of any representation or warranty to be true and correct in any material respect;

· default by the Borrower or an affiliate of the Borrower in the payment of any amount due with respect to other indebtedness in excess of $25.0 million, or any default in the performance of any obligation or condition with respect to such indebtedness beyond the applicable grace period if the effect of the default is to permit or cause the acceleration of the indebtedness;

· bankruptcy or insolvency events involving the Borrower or an affiliate of the Borrower;

· the entry of, and failure to pay, one or more adverse judgments in excess of $25.0 million in the aggregate (or in the case of a non-monetary judgment, having a material adverse effect) against which enforcement proceedings are brought or that are not stayed pending appeal; and

· the invalidity or unenforceability of any material provision in the Subordinated Credit Agreement or related documents;

If an event of default occurs as a result of any bankruptcy or insolvency events involving the Borrower or an affiliate of the Borrower, the Subordinated Loan Commitment shall terminate immediately and the Subordinated Loans (with accrued interest thereon) and all other amounts owing under the Subordinated Credit Agreement and related documents shall immediately become due and payable. Indebtedness under the Subordinated Credit Agreement will be subordinated in right of payment to indebtedness under the Senior Credit Agreement, but will rank equal in right of payment to all other indebtedness of the Borrower.

The information in Item 1.01 with respect to the Subordinated Credit Agreement dated May 1, 2009, is hereby incorporated by reference into this Item 2.03.
