Exelon and PSEG Announce Agreement with U.S. Department Of Justice

CHICAGO and NEWARK (June 22, 2006) — Exelon Corporation (NYSE: EXC) and Public Service Enterprise Group Incorporated (NYSE: PEG) announced today that they have reached a comprehensive agreement with the Antitrust Division of the United States Department of Justice (DOJ), which resolves all competition issues reviewed by the DOJ in connection with the proposed merger of Exelon and PSEG.

Under the terms of the DOJ agreement, Exelon and PSEG will divest fossil-fuel fired electric generating stations with a total capacity of approximately 5,600 megawatts, assuring that the merger will not adversely affect competition. No divestiture of nuclear capacity or nuclear plants would be required by DOJ, as the increased fossil divestiture will resolve all competition issues. The fossil divestiture required by the settlement with DOJ will satisfy the requirements imposed by the Federal Energy Regulatory Commission (FERC) to divest fossil generation. The virtual nuclear divestiture approved by FERC in June 2005 continues to be a FERC requirement even though it is not required by DOJ. The divestitures will be required only if the merger closes.

“Our agreement with DOJ is a major milestone, and we are moving ahead to get our last remaining regulatory approval from the New Jersey Board of Public Utilities,” said John W. Rowe, chairman, president, and CEO of Exelon. “The DOJ’s comprehensive investigation and analysis encompassed millions of pages of documents, including testimony and other evidence presented by the staff of the New Jersey Board of Public Utilities, the New Jersey Ratepayer Advocate, and many other parties in the New Jersey proceedings. We are hopeful that the DOJ resolution will provide positive momentum that will enable us to complete our discussions in New Jersey as soon as possible.”

The final decision on whether to proceed with the merger will rest with the boards of both Exelon and PSEG after the terms and conditions of regulatory requirements are known.

Closing is anticipated in the third quarter upon completion of all required regulatory actions.

The agreement with DOJ requires Exelon Electric & Gas to enter into agreements within 150 days after the merger closes to sell the following power plants and would give DOJ approval rights over the buyers to assure a competitive market after the divestiture:

• Linden, a 1,544 MW combined cycle natural gas and peaking (gas/oil) facility owned by PSEG (Linden, N.J.)

• Eddystone, a 1,408 MW coal-fired, mid-merit (oil/gas) and peaking (oil) facility owned by Exelon (Eddystone, Pa.)

• Mercer, a 777 MW coal- and natural gas/oil-fired facility owned by PSEG (Hamilton, N.J.)

• Hudson, a 991 MW coal- and natural gas-fired facility owned by PSEG (Jersey City, N.J.)

• Sewaren Units 1-4, a 453 MW natural gas/oil steam facility owned by PSEG (Woodbridge, N.J.)

• Cromby, a 345 MW coal- and natural gas/oil-fired facility owned by Exelon (Phoenixville, Pa.)

The divestiture would be the largest required in an energy company merger, involving 26 generating units located at these six plants.

The agreement with DOJ is embodied in a consent decree filed with the United States District Court for the District of Columbia. The consent decree resolves all competition issues found by DOJ after an exhaustive evaluation over 15 months involving a review of approximately 9 million pages of documents, scores of interviews and depositions, and extensive analysis of the competitive effects of the proposed merger. DOJ’s analysis included the energy and capacity markets in PJM, the vertical market concentration issues associated with combination of the electric and gas assets of the two companies, and the New Jersey Basic Generation Service (BGS) auction.

“We believe the comprehensive nature of DOJ’s review, with its antitrust expertise and considerable resources, provides substantial assurance that the merger will not adversely affect competition, considering the extensive divestiture required and the approval and enforcement mechanisms that are included in the consent decree. Following the divestitures required by DOJ, the combined company will have less fossil generation in the PJM East region than PSEG has today. The agreement will allow us to keep our nuclear generation. In fact, we believe the merger will be pro-competitive and, with increased output of low-cost nuclear generation resulting from the merger, will provide substantial energy cost reductions to customers in New Jersey and Pennsylvania as well as improved safety and reliability,” added E. James Ferland, chairman and CEO of PSEG.

Exelon and PSEG expect to begin the asset-sale process shortly, in order to execute sales promptly following the close of the merger.
