2006 Earnings Guidance The outlook for 2006 adjusted (non-GAAP) operating earnings is Exelon stand-alone and excludes unrealized mark-to-market adjustments from non-trading activities, income resulting from investments in synthetic fuel-producing facilities, significant impairments of intangible assets, certain severance costs, and costs associated with the proposed merger with PSEG. These estimates do not include any impact of future changes to GAAP. Earnings guidance is based on the assumption of normal weather.
