Exhibit Index 17 Signatures 18 Exhibits 19 INDEPENDENT AUDITOR'S REPORT To the Exelon Corporation Employee Savings Plan Committee: We have audited the accompanying statements of net assets available for benefits of the EXELON CORPORATON EMPLOYEE SAVINGS PLAN (the "Plan") as of December 31, 2002 and 2001, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the EXELON CORPORATION EMPLOYEE SAVINGS PLAN as of December 31, 2002 and 2001, and the changes in net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States of America. Our audits were made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held at end of year as of December 31, 2002 is presented for purposes of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974, as amended. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, is fairly stated, in all material respects, in relation to the basic financial statements taken as a whole.

The following description of the Exelon Corporation Employee Savings Plan (the "Plan") is provided for general information purposes only. The official text of the Plan, as amended, should be read for more complete information. a. General. The Plan was established by Commonwealth Edison Company, effective March 1, 1983, to provide a systematic savings program for eligible employees and to supplement such savings with employer contributions. On March 30, 2001 the Commonwealth Edison Employee Savings and Investment Plan was combined with the PECO Energy Company Employee Savings Plan to become the Exelon Corporation Employee Savings Plan. The Plan is subject to the applicable provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), and the Internal Revenue Code of 1986, as amended (the "Code"). The Plan provides generally that any regular employee of Exelon Corporation (the "Corporation") and any other affiliated company that adopts the Plan with the consent of the Corporation is eligible to elect to participate in the Plan. There were 23,872 and 24,532 participants in the Plan at December 31, 2002 and 2001, respectively. The Corporation is the administrator of the Plan ("Plan Administrator") and has the sole authority to appoint and remove members of the Plan committee, the trustee, and any investment manager which may be provided for under the trust. The Plan committee has the responsibility for day-to-day administration of the Plan. Fidelity Management Trust Company is the Plan trustee ("Trustee") and Fidelity Investments Institutional Operations Company, Inc. is the Plan recordkeeper. b. Contributions. The Plan permits salaried and non-union hourly employees to contribute between 1% and 20% of their normal base pay each pay period on a pre-tax basis, an after-tax basis or a combination of the two. For Exelon subsidiaries that have adopted the Plan on behalf of their salaried and non-union hourly employees, the company matches contributions at a rate of 100% of the first 5% of contributions (whether pre-tax or after-tax). The Plan permits union-represented employees to contribute between 1% and 15% of the sum of their normal base pay plus certain overtime on a pre-tax basis and between 1% and 10% on an after-tax basis. Although the Plan permits contributions of up to 15% of base pay on a pre-tax basis and up to 10% of base pay on an after-tax basis, the combined maximum employee contributions may not exceed 20%. For Exelon subsidiaries that have adopted the Plan on behalf of their union employees, the company matches contributions at a rate of 100% of the first 2% contributed, 84% of the following 1% contributed, 83% of the following 2% contributed, and 25% of the following 1% contributed. Effective August 1, 2002, during any calendar year in which participants attain age 50 or older, they may elect to make additional pre-tax contributions, called "catch-up" contributions to the Plan. In order to be eligible to make catch-up contributions, participants must anticipate that their Plan pre-tax contributions will reach the applicable annual IRS limit on that type of contribution or be contributing at the maximum base pay level. c. Investment Options. The Plan investments are fully participant directed. The investment options provided under the Plan are described as follows: The Exelon Corporation Stock Fund seeks to increase the value of each account over the long term by investing in Exelon Corporation common stock and short-term investments. The amount of the short-term investments is based upon a target established by the Plan sponsor, but the actual amount 5 EXELON CORPORATION EMPLOYEE SAVINGS PLAN ---------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) ----------------------------------------- of short term investments on any given business day will vary with the amount of cash awaiting investment and participant activity of the fund (contributions, redemptions, exchanges, and withdrawals).

Each Freedom Fund invests in a combination of underlying Fidelity stock, bond, and money market mutual funds. The allocation strategy among the underlying stock, bond, and money market mutual funds contained in each Freedom Fund with a target retirement date is based on the number of years until a participant's anticipated retirement. For the funds with a target retirement date, the mix of underlying funds will gradually become more conservative over time. The Fidelity Freedom Income Fund seeks high current income and, as a secondary objective, some capital appreciation for those already in retirement.

These securities are issued by U.S. and foreign corporations, governments, banks and U.S. agencies such as Fannie Mae and the Student Loan Marketing Association. These investments are considered low risk due to the financial strength of the issuers and the short-term maturity of the investments. The BGI Extended Equity Market Fund Class K is a fund managed by Barclays' Global Investors, N.A. that invests in small and mid-sized U.S. stocks. The fund invests in stocks that comprise the BGI Extended Market Index ("Index"). The fund will invest in these types of investments in approximately the same proportion as the Index.

The following funds were discontinued as of April 30, 2002: U.S. Equity Index Commingled Pooled, White Oak Growth Fund, and the Fidelity Retirement Money Market Fund. The assets were transferred to the other various funds described above. e. Participant Loans. A participant may, upon application, borrow from the Plan. Only one loan is permitted to a participant in any calendar year (with a maximum of five loans outstanding at any time) and the loan shall not be less than $1,000. The aggregate amount of all outstanding loans may not exceed the lesser of (i) 50% of a participant's vested balance in the Plan or, (ii) $50,000 minus the excess of the highest outstanding balance of all loans from the Plan to the participant during the previous 12-month period over the outstanding balance of all loans from the Plan to the participant on the day the loan is made. For a general purpose loan, the maximum period is five years. For a home loan the maximum term is fifteen years, and the minimum is five years. The interest rate on all loans is the prime rate for commercial loans plus 1%. No lump-sum or installment distribution from the Plan will be made to a participant who has received a loan, or to a beneficiary of any such participant, until the loan, including interest, has been repaid out of the funds otherwise distributable. f. Vesting of Participants' Accounts. A participant's after-tax contributions account, before-tax contributions account, employer matching contributions account, and rollover account are fully vested at all times. g. Withdrawals by Participants While Employed. A participant may withdraw up to the entire balance of the participant's after-tax contributions account once each calendar year. After making such a withdrawal, the participant must wait six months before making a new election to resume contributions to the Plan. A participant may also withdraw up to an amount equal to the balance in his or her rollover account. A participant may make withdrawals from the participant's before-tax contributions, but only if the participant has attained age 59-1/2 or, prior to that age, only in an amount required to alleviate financial hardship as defined in the Code and regulations thereunder. Financial hardship withdrawals from a before-tax contributions account suspend the participant's right to make contributions to the Plan for six months. While any loan to the participant remains outstanding, the amount available for withdrawal shall be the balance in such account less the balance of all outstanding loans. h. Distributions upon Termination of Employment. Upon termination of employment, retirement, total disability or death of a participant, distribution of the balances of the participant's after-tax contributions account, before-tax contributions account, rollover account and employer matching contributions account is made to the participant or, in the event of the participant's death, to the participant's designated beneficiary or beneficiaries. Such distribution will be made, as elected by the participant, in the form of either a lump-sum payment or in substantially equal annual installments over a period not exceeding the lesser of 15 years or the life expectancy of the participant or beneficiary, as the case may be. A participant may elect to defer distributions until age 70-1/2. If the value of a participant's 9 EXELON CORPORATION EMPLOYEE SAVINGS PLAN ---------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) ----------------------------------------- account is greater than $5,000 the participant can leave his or her account in the plan. Distributions will be taxed as ordinary income in the year withdrawn and may also be subject to an early withdrawal penalty if taken before age 59 1/2, unless eligible rollover distributions are rolled over to another qualified plan or an IRA. A 20% mandatory federal income tax withholding applies to withdrawals that are eligible for rollover, but which are not directly rolled over to another qualified plan or an IRA. i. Administrative Expenses. Administrative expenses for recordkeeping services as well as trustee services, which include custodial, administrative and fiduciary services, are paid out of the Plan assets. j. Participant Accounts. Each participant's account is credited with the participant's contribution and allocations of (a) the Company's contribution and (b) Plan earnings, and charged with an allocation of administrative expenses. Allocations are based on participant elections or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. k. Reclassifications. Certain 2001 amounts have been reclassified to conform to 2002 presentation. These reclassifications have no effect on the net assets available for benefits as of December 31, 2001. (2) Summary of Significant Accounting Policies. The significant accounting policies followed by the Plan are as follows: a. General. The Plan follows the accrual method of accounting for recording contributions from participants and employers, income from investments, purchases and sales of investments, and administrative expenses. Benefits are recorded when paid. b. Use of Estimates. The preparation of financial statements in conformity with generally accepted accounting principles requires the plan administrator to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results may differ from those estimates. c. Investment Valuation and Income Recognition. The Plan presents in the statements of changes in net assets available for benefits the net appreciation (depreciation) in the fair value of its investments which consists of the realized gain (loss) on the sale of securities and the unrealized appreciation (depreciation) in the fair value of investments. Guaranteed investment contracts are fully benefit responsive and are reported at contract value, which is cost plus accrued interest; for synthetic investment contracts, contract value is equal to the fair value of the collateral plus the benefit responsive wrap value. Investments in Exelon Corporation Common Stock are valued at the closing sales price as reported on the New York Stock Exchange. 10 EXELON CORPORATION EMPLOYEE SAVINGS PLAN ---------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) ----------------------------------------- Short-term investments held by various institutional funds of the UBS Global Asset Management Trust Company are stated at cost which approximates current value. Investments in certain of the various funds that make up the UBS Multi-Asset Portfolio are valued at the latest reported sale price on the valuation date used for securities traded on United States and foreign stock exchanges. Investments valued in foreign currencies are converted into U.S. dollars based on quoted foreign exchange rates on that date and are valued at the latest quoted bid price or at estimated current value as determined by the fund trustee. Investments of registered securities are valued at the last sale price, or if no sale price, at the closing bid price. Short-term securities maturing within sixty days of their purchase date are valued at amortized cost or original cost plus accrued interest, both of which approximate current value. Participant loans are valued at cost, which approximates fair value. Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. d. Recent Accounting Pronouncements. In June 1998, the Financial Accounting Standards Board (FASB) issued SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities," to establish accounting and reporting standards for derivatives. SFAS No. 133 was subsequently amended by SFAS No. 137 and SFAS No. 138. These new standards require that all derivatives be recognized at their fair value as either assets or liabilities on the balance sheet and specify the accounting for changes in fair value depending upon the intended use of the derivative. The Plan was required to adopt SFAS No. 133, as amended, in the fiscal year ended December 31, 2001. (3) Net Appreciation/Depreciation of Investments. During 2002 and 2001, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated/(depreciated) in value as follows: 2002 2001 ---- ---- Exelon Corporation Common Stock $ 15,044,105 $(49,279,285) Registered Investment Companies (289,937,862) (150,433,690) Collective Institutional Investment Trust Funds (3,976,004) (21,318,659) ------------- -------------- $(278,869,761) $(221,031,634) ============= ============== 11 EXELON CORPORATION EMPLOYEE SAVINGS PLAN ---------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) ----------------------------------------- (4) Investments. The current values of the Plan's investments at December 31, 2002 and 2001, which represent 5% or more of the Plan's net assets, are summarized as follows: 2002 2001 ---- ----- Fidelity Managed Income Portfolio II $224,024,411 $277,550,439 UBS Collective Investment Trust, Multi Asset Portfolio Fund 155,999,960 167,140,136 Exelon Corporation Common Stock 119,920,775 112,994,136 Fidelity Magellan Fund 143,155,225 193,440,584 Fidelity Growth Company Fund 166,097,506 243,554,370 Fidelity U.S. Equity Index Commingled Pool - 165,086,228 BGI Equity Index T Fund 112,827,032 - Fidelity Dividend Growth Fund 112,395,883 141,508,736 Legg Mason Value Trust Institutional Shares 188,387,040 249,075,664 Fidelity Contrafund 128,875,927 148,202,380 PIMCO Total Return Fund - Inst. Class 98,193,027 - (5) Investment Contracts. In 2002 and prior years, the Plan entered into several benefit-responsive investment contracts with various insurance companies and other financial institutions. The contract providers maintain the contributions in a general account. Some investment contracts are purchased in conjunction with the investment by the Plan in fixed-income securities. Investment contracts provide for the payment of a specified rate of interest. The account is credited with earnings at the specified rate and charged for participant withdrawals and administrative expenses. The contracts are included in the financial statements at contract value, as reported to the Plan by the contract providers. Contract value represents contributions made under the contract, plus earnings, less participant withdrawals and administrative expenses. Plan participants may ordinarily direct the withdrawal or transfer of all or a portion of their investment at contract value. There are no reserves against contract value for credit risk of the contract issuer or otherwise. The weighted average yield for all such contracts was approximately 5.9 percent for 2002 and 5.7 percent for 2001. The crediting interest rate was 6.0 percent at December 31, 2002 and 2001. The crediting interest rate generally cannot be less than the contract rate. (6) Investments in Derivative Financial Instruments. The UBS Collective Investment Trust, Multi-Asset Portfolio Fund and some of the funds in which it invests participate in various equity index futures contracts and foreign currency contracts. The assets of this fund are invested as follows: 51% equities, 22% bonds, 10% real estate, 11% derivatives, and 6% venture capital. A futures contract is an agreement involving the delivery of a particular asset on a specified future date at an agreed upon price. Risks of entering into futures contracts include the possibility that there may be an illiquid market and that changes in the value of the contracts may not correlate with changes in the value of the underlying securities. Open futures contracts are valued at the settlement price established each day on the exchange on which they are traded. These contracts are marked to market daily with the resulting gain or loss included in the net realized gain or loss from futures contracts. A forward exchange contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated forward rate. Risks associated with such contracts include movement in the value of the foreign currency relative to the U.S. dollar and the ability of the counterparty to perform. 12 EXELON CORPORATION EMPLOYEE SAVINGS PLAN ---------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONTINUED) ----------------------------------------- The contracts are valued at foreign exchange rates, and the changes in value of open contracts are recognized as unrealized appreciation/depreciation. The realized gain or loss on forward currency contracts represents the difference between the value of the original contracts and the closing value of such contracts. Similarly, some or all of the Fidelity funds, the Morgan Stanley International Equity Portfolio, and the BGI EAFE Equity Index Fund-Class K may use (1) foreign currency contracts to facilitate transactions in foreign securities and to manage the fund's currency exposure and (2) futures and options contracts to manage its exposure to the stock and bond markets and to fluctuations in the interest rates and currency values. Such funds also may invest in indexed securities whose values are linked either directly or inversely to changes in foreign currencies, interest rates, commodities, indices, or other underlying instruments. (7) Risks and Uncertainties. The Plan provides for various investment options in several investment securities and instruments, including common stock of Exelon Corporation. Investment securities are exposed to various risks, such as interest rate, market and credit risks. Due to the level of risks associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risks and values in the near term would materially affect participants' account balances and the amounts reported in the statement of net assets available for benefits and the statement of changes in net assets available for benefits. No collateral or other security is required by the Trustee to collateralize these financial statements. (8) Income Tax Status. The Internal Revenue Service ("IRS") has issued a determination letter that the Plan, as amended and restated January 1, 1995, is a qualified plan under Section 401(a) and 401(k) of the Code, and the Trust established under the Plan, as in effect as of the amendments of January 1, 1995, is tax exempt under Section 501(a) of the Code. Although the Plan has been amended since receiving the determination letter, the Plan Administrator and the Plan's tax counsel believe that the Plan is currently designed and being operated in compliance with the applicable requirements of the Code. Therefore, they believe that the Plan was qualified and the related trust was tax-exempt as of the financial statement date. (9) Plan Amendments. If a participant invests any portion of his or her account in the Exelon Corporation Stock Fund and is eligible to receive dividend distributions from the Plan, then effective January 1, 2002, the participant is deemed to have elected to have the dividends reinvested in the Exelon Corporation Stock fund. If the participant prefers to receive any such dividends in cash, he or she can so elect by contacting Fidelity. Dividends distributed to the participant in cash from the Plan are subject to income tax as a dividend, and affected participants will receive an IRS Form 1099DIV for the dividends in the year following receipt (Form 1099R if participants take a full distribution of their Plan accounts). (10) Plan Termination. The Plan may be amended, modified or terminated by the Corporation at any time, subject to certain rights of participants under the Plan. The Plan may also be terminated if the Plan is disqualified by the IRS. Termination of the Plan with respect to a participating employer may occur if there is no successor employer in the event of dissolution, merger, consolidation or reorganization of such employer company. In the event of full or partial termination of the Plan, assets of affected participants of the terminating employer or employers shall remain 100% vested and distributable at fair market value in the form of cash, securities or annuity contracts, in accordance with the provisions of the Plan. The Corporation has no current intentions of terminating the Plan. 13 EXELON CORPORATION EMPLOYEE SAVINGS PLAN ----------------------------------------- NOTES TO FINANCIAL STATEMENTS (CONCLUDED) ----------------------------------------- (11) Plan Mergers. Effective November 1, 2002, the net assets ($1,080,732) of the Systems Corp. 401(k) Retirement Plan, were merged with and into the Plan. Effective March 30, 2001, the net assets of the following plans were merged with and into the Plan: PECO Energy Company Employee Savings Plan $720,059,169 Bumler Heating and Specialties, Inc. 401(k) Profit Sharing and Savings Plan 1,426,975 Midwest Mechanical 401(k) Profit Sharing and Savings Plan 2,784,099 V.A. Smith Company 401(k) Profit Sharing and Savings Plan 222,762 ------------ $724,493,005 ============ (12) Related Party Transactions. Investment options in the Plan include mutual funds managed by Fidelity Management Trust Company, the Trustee as defined by the Plan. Also, the Plan holds shares of Exelon Corporation common stock. These transactions qualify as exempt party-in-interest transactions. There have been no known prohibited transactions with a party-in-interest. 14 EXELON CORPORATION EMPLOYEE SAVINGS PLAN ---------------------------------------- SCHEDULE OF ASSETS (HELD AT END OF YEAR) ---------------------------------------- AS OF DECEMBER 31, 2002 ----------------------- Schedule H, Part IV, Item 4i, Form 5500 --------------------------------------- Employer Identification Number 23-2990190, Plan Number 003 ----------------------------------------------------------- No of Shares or Current No. of Units Description Cost** Value ------------------------- ------------------------------------------------------------ ---------------- ------------------ COMMON STOCKS ------------- * 6,011,725 shares Exelon Corporation Common Stock $ 119,920,775 ------------------ COLLECTIVE FUNDS ---------------- * 142,126 units UBS Collective Investment Trusts, Multi-Asset Portfolio Fund 155,999,960 * 4,443,759 units BGI Equity Index T 112,827,032 * 16,018 units BGI EAFE Equity Index K 166,105 * 49,135,114 shares BGI Money Market I 49,135,114 * 29,692 shares BGI Extended Market K 557,312 * 460,317 shares BGI US Debt K 8,571,101 * 224,024,411 units Fidelity Managed Income Portfolio II 224,024,411 ------------------ 551,281,035 ------------------ REGISTERED INVESTMENT COMPANIES ------------------------------- * 1,813,009 shares Fidelity Magellan Fund 143,155,225 * 3,338,755 shares Fidelity Contrafund 128,875,927 * 4,689,371 shares Fidelity Growth Company Fund 166,097,506 * 2,695,324 shares Fidelity Low-Priced Stock Fund 67,841,300 * 5,035,658 shares Fidelity Dividend Growth Fund 112,395,883 * 361,842 shares Fidelity Freedom Income Fund 3,835,524 * 617,292 shares Fidelity Freedom 2000 Fund 6,796,385 * 1,922,531 shares Fidelity Freedom 2010 Fund 21,993,756 * 2,378,581 shares Fidelity Freedom 2020 Fund 25,308,106 * 1,303,933 shares Fidelity Freedom 2030 Fund 13,352,277 * 119,612 shares Fidelity Freedom 2040 Fund 700,926 * 9,202,720 shares PIMCO Total Return Fund (Institutional Class) 98,193,027 * 4,703,928 shares T.
