Agenda The Exelon Story ComEd PECO Exelon Generation Exelon Today's discussion will focus on "The Next Five Years", including earnings drivers for 2007 - 2011 by Operating Company

The Exelon Story - Value Driven Demonstrated ability to add value during transformation from an integrated utility to a predominantly merchant generator Premier U.S. nuclear generator uniquely positioned to capture market opportunities through operational and commercial excellence Primary source of Exelon's value going forward ~10% average annual operating EPS growth since inception Continued strong growth trend through 2011 Strong balance sheet and financial discipline Realigning value return framework Experienced management team Predictable source of earnings through transition period; preparing for 2011 Completing the transition to a "wires-only" business with a regulatory recovery plan in place Note: See presentation appendix for adjusted (non-GAAP) operating reconciliations to GAAP

ComEd Operating Earnings: 2007 Estimate As a "wires-only" company, ComEd was always expected to earn less on an operating basis in 2007 than in prior years. The unfavorable ICC Order in the Distribution Case further depressed ComEd's 2007 earnings outlook. 510 250 80 20 50 55 - - End of transition period - - Regulatory lag ('04 Test Yr) Inflation CapEx - Depreciation + DST rate request + Load growth - - DST disallowance(2) + DST rehearing outcome $510M - $530M $250M - $300M $80M - $135M (1) 2006 Operating Earnings Guidance; see appendix for reconciliation of adjusted (non-GAAP) operating EPS to GAAP EPS (2) Reflects disallowance of pension asset and A&G expenses and modified capital structure and ROE; refer to Appendix for details (3) Preliminary 2007 Operating Earnings Guidance which will be updated at Exelon's Annual Investor Conference on 12/12/06 Risks & Opportunities +/- Load growth +/- Spending +/- DST rehearing outcome +/- Transmission rate case outcome Key Assumptions(3) Rate Base: $7.6B Equity: ~43% ROE: 2.5 - 4.1% Based on ComEd's Request in the Delivery Service Tariff (DST) Case Based on the ICC Order in the DST Case 2006 Guidance(1) 2007 - DST Request 2007 Preliminary Guidance(3)

Low 80 55 ComEd Operating Earnings: Next Five Years $80M - $135M 2007 - 2011 Earnings Drivers Regular DST Rate Requests (Minimize Regulatory Lag) Rate Base Growth Load Growth After 2007, assuming no rate freeze legislation or similar event, ComEd's earnings are expected to increase as regulatory lag is reduced over time through regular rate requests, putting ComEd on a path toward appropriate returns and solid credit metrics Executing ComEd's Regulatory Recovery Plan Investment is required over the next five years to: Maintain and improve the reliability of ComEd's system Meet growing customer requirements Improve customer service 2011 ComEd - 2011 Assumptions Rate Base: ~$9.6B Equity: ~45% ROE: ~10% 2007 Preliminary Guidance(1) (1) Preliminary 2007 Operating Earnings Guidance which will be updated at Exelon's Annual Investor Conference on 12/12/06

Important ComEd Milestone: Purchased Power Cost Recovery ICC authorized recovery of purchased power costs in the Distribution Case Rate Order - July 2006 Illinois auction approved - September 2006 Culmination of nearly three-year process to approve procurement methodology Resulted in customer rates lower than those in 1995 Implications of a rate freeze extension (if proposed legislation were enacted and upheld) ComEd would pay substantially more for its purchased power and operating costs than it would be allowed to collect Would result in a significant cash flow deficit which would ultimately drive ComEd into insolvency and bankruptcy

Nuclear Going Forward Recently announced intent to apply for Construction & Operating License ("COL") in ERCOT by end of 2008 Preserves option to participate in Energy Policy Act incentives Supports NRC resource planning New nuclear designs offer improved features, passive safety systems, competitive capital costs and shorter construction times ERCOT is an attractive market for new nuclear Growing demand for power and robust market prices State and local support for new nuclear Provides emissions-free generation in an area with air quality concerns Existing presence in ERCOT Exelon's phased approach allows for go/no-go decisions at major funding/commitment milestones

Exelon's changing composition of earnings warrants a new value return policy Existing dividend policy based on a business mix in which the regulated utilities contributed a larger share of earnings Existing share repurchase program designed solely to offset dilution from shares issued under Exelon's incentive plans The new policy will: Establish a base dividend Return excess cash and/or balance sheet capacity through share repurchases After funding maintenance capital and committed dividends In absence of higher value-added growth opportunities Maintain adequate credit metrics on a prospective basis Details of the Value Return Policy will be discussed at Exelon's Annual Investor Conference on December 12th, 2006 Value Return Policy

ComEd Regulatory Update Distribution Rate Case ICC Order provided for $8M increase, vs. the Administrative Law Judges' (ALJs') Proposed Order of $164M and ComEd's original request of $317M Due to the ICC Order, ComEd and Exelon recorded an after-tax impairment charge of ~$776M in 3Q06 based on results of ComEd's interim goodwill impairment analysis On August 30, ICC voted 5-0 to grant key elements of ComEd's request for rehearing (ICC has 150 days to complete rehearing process) Key issues on rehearing Administrative & General Expense: Seeking approval of disallowed costs ($62M improvement to ICC Order) Pension Asset: Seeking to recover pension expense as if ComEd had funded contribution through debt or, alternatively, to recover pension expense as if contribution had never been made ($25-$35M improvement to Order) Common Equity Ratio: Seeking to establish a 46% common equity ratio as recommended in ALJs' Proposed Order, rather than the ICC Order's 42.86% common equity ratio ($17M improvement to Order) Governmental Consolidated Billing (GCB) Rider: Seeking to either eliminate the Rider or ensure acceptable allocation of annual subsidy ($116M) to other customers ICC order anticipated by year-end

ComEd Regulatory Update (cont'd) Residential Rate Stabilization Case On August 29, ComEd submitted a modified plan that ICC Staff supports: "10/10/10" caps from 2007 to 2009; deferral recovery from 2010 to 2012 with 6.5% annual carrying charge Phase-in plan is optional (residential customers may "opt-in" through August 22, 2007) A similar program at Potomac Electric experienced "opt-in" participation rates of 2-3% On October 25, the Administrative Law Judge recommended ICC approval of ComEd's plan ICC decision anticipated late November 2006

Effective January 17, 2005, Generation began overseeing daily plant operations at the Salem and Hope Creek nuclear stations through an Operating Services Contract with PSEG Nuclear, LLC, which terminates on January 17, 2007 with a two- to three-year transition period. Last refueling outages: Salem Unit 1 completed November 2005 and Unit 2 began October 10, 2006.

(b)		Clinton, Oyster Creek and Three Mile Island are operated by AmerGen, wholly owned by Generation.

(c)		A December 2004 order permits Oyster Creek to operate beyond its license expiration if the NRC has not completed its renewal application review.

Exelon Generation — Total Electric Generating Capacity

Owned net electric generating capacity by station at December 31, 2005; does not include properties held by equity method investments:

Base-load units are plants that normally operate to take all or part of the minimum continuous load of a system, and consequently produce electricity at an essentially constant rate. Intermediate units are plants that normally operate to take load of a system during the daytime higher load hours, and consequently produce electricity by cycling on and off daily. Peaking units are plants that usually house low-efficiency, quick response steam units, gas turbines, diesels, or pumped-storage hydroelectric equipment normally used during the maximum load periods.
