Section 8 — Other Events.
Item 8.01. Other Events.

On February 8, 2006, Exelon Corporation (Exelon) and Public Service Enterprise Group Incorporated (PSEG) issued a joint press release including an update on the schedule for the review by the New Jersey Board of Public Utilities (NJBPU) of the proposed merger of PSEG and Exelon. A copy of the press release is attached as Exhibit 99 to this Report on Form 8-K. There are a number of regulatory approvals or other regulatory actions required to consummate the merger, including those described in previous Reports on Form 8-K.

Remaining regulatory reviews include the U.S. Department of Justice, among others. Exelon and PSEG now expect to complete all of the regulatory reviews and close the merger in the third quarter of 2006. It may occur earlier if a settlement is concluded and accepted by the NJBPU.

Although Exelon and PSEG believe that the expectations as to timing of the regulatory proceedings described above are reasonable, no assurances can be given as to the timing of the receipt of any required regulatory approvals or that all required approvals will be received.
