Section 1 – Registrant’s Business and Operations

Item 1.01 Entry into a Material Definitive Agreement.

On February 23, 2006, Commonwealth Edison Company (ComEd) issued a press release reporting that ComEd had entered into a $1 billion senior secured 3-year revolving credit agreement (Credit Agreement) with JPMorgan Chase Bank N.A., as administrative agent, and the lenders party to the Credit Agreement. A copy of ComEd’s press release is attached hereto as Exhibit 99.1.

Pursuant to the Credit Agreement, ComEd may borrow, repay, and reborrow funds, subject to the terms and conditions of the Credit Agreement, at any time and from time to time up to February 20, 2009. Borrowings under the Credit Agreement and other specified obligations of ComEd and its subsidiaries to the lenders party to the Credit Agreement are secured by a First Mortgage Bond of ComEd in the principal amount of $1,008,000,000 issued pursuant to the Mortgage dated July 1, 1923, as amended and supplemented by supplemental indentures, including the Supplemental Indenture dated August 1, 1944 (Mortgage) and the Supplemental Indenture dated as of February 1, 2006. The Mortgage is a first mortgage lien on ComEd’s utility assets.

The Credit Agreement was established to finance the working capital needs of ComEd and its subsidiaries and for other general corporate purposes. The credit facility is also available for the issuance of letters of credit. Lending commitments under the Credit Agreement terminate on February 20, 2009.

Loans under the Credit Agreement carry interest at a variable rate determined, at ComEd’s option, by either the Base Rate or a Eurodollar Rate, plus, in either case, an applicable margin determined with reference to ComEd’s senior secured long term debt ratings. ComEd is also required to pay a utilization fee equal to 0.25% of all loans and outstanding letters of credit, for each day that the outstanding principal amount of loans under the facility, plus the undrawn amount of outstanding letters of credit and unpaid letter of credit reimbursement obligations, exceeds 50% of the aggregate commitment of the lenders under the Credit Agreement. The Credit Agreement also requires a commitment fee payable by ComEd on the last day of each calendar quarter and on the date on which the commitments to lend under the Credit Agreement are reduced to zero. The commitment fee is a per annum rate, determined according to ComEd’s senior secured debt ratings, on the average daily unused amount of the facility.

The Credit Agreement includes representations and warranties, affirmative and negative covenants, and events of default customary for financing transactions of this type. In addition, under the Credit Agreement, ComEd may issue additional First Mortgage Bonds under the Mortgage only if, after giving effect to the proposed issuance, ComEd would continue to have available sufficient bondable credits to support the issuance of at least an additional $1.75 billion of First Mortgage Bonds under the Mortgage. The Credit Agreement also requires ComEd to maintain a ratio of adjusted funds from operations to net interest expense of at least 2.25 to 1.0.

Reference is made to the complete Credit Agreement attached as Exhibit 99.2 for additional covenants, terms and conditions, including events of default.

On February 22, 2006, ComEd, Exelon Corporation (Exelon), PECO Energy Company (PECO), and Exelon Generation Company LLC (Generation) executed amendments to three credit facilities to which ComEd was a party with Exelon, PECO and Generation. The amendments remove ComEd as a borrower and remove provisions that would treat ComEd as a significant subsidiary under: (1) the Three Year Credit Agreement dated October 31, 2003; (2) the Five Year Credit Agreement dated July 16, 2004; and (3) the Credit Agreement dated October 28, 2005.
