ITEM 9. WHOLESALE GENERATORS AND FOREIGN UTILITY COMPANIES

Part I

a.)     Sithe Energies, Inc.
        335 Madison Avenue, 28th Fl.
        New York, New York  10017

        Sithe Energies, Inc. (Sithe) is an independent power generator in North
        America utilizing primarily fossil and hydro generation. The purchase
        involves approximately 10,000 megawatts (MW) of generation consisting of
        3,800 MW of existing merchant generation, 2,500 MW under construction,
        and another 3,700 MW of generation in various stages of development, as
        well as Sithe's domestic marketing and development businesses. The
        generation assets are located primarily in Massachusetts and New York,
        but also include plants in Pennsylvania, California, Colorado and Idaho,
        as well as Canada and Mexico.

        Exelon owns 49.9% of Sithe and holds the option to purchase the
        remaining 50.1% interest in Sithe between December 2002 and December
        2005 at a price based on prevailing market conditions.


        AmerGen Energy Company, L.L.C.
        200 Exelon Way,  Suite 345
        Kennett Square,  Pennsylvania  19348

        Exelon and British Energy, Inc., a wholly owned subsidiary of British
        Energy plc, formed AmerGen Energy Company, L.L.C. (AmerGen) to pursue
        opportunities to acquire and operate nuclear generating stations in the
        United States. Exelon owns a 50% equity interest in AmerGen. AmerGen
        owns and operates Clinton Nuclear Power Station, Three Mile Island Unit
        No. 1 Nuclear Generating Facility, and Oyster Creek Nuclear Generation
        Facility with an aggregate capacity of 2,378 MW.


b.)     At December 31, 2000, Exelon's aggregate capital investment in all EWGs
        and FUCOs was approximately $748.0 million of which $704.0 was invested
        in Sithe and $44.0 million was invested in AmerGen.

        Exelon Generation and British Energy have each agreed to provide up to
        $100 million to AmerGen at any time for operating expenses. Exelon
        anticipates that Exelon Generation's capital expenditures will be funded
        by internally generated funds, Exelon Generation borrowings or capital
        contributions from Exelon. Exelon Generation's borrowings may be
        initially guaranteed by Exelon as a result of Exelon Generation's lack
        of separate operational history.

c.)     Exelon accounts for its investments in Sithe and AmerGen using the
        equity method of accounting whereby Sithe and AmerGen financial
        statements are not consolidated with the financial statements of Exelon.

        At December 31, 2000, the consolidated capitalization ratio of Exelon
        was: debt 66%, common equity 31%, and preferred securities of
        subsidiaries of 3%. (For these purposes, "consolidated debt" means all
        long-term debt, long-term debt due within one year, notes payable and
        other short-term obligations, including any short-term debt and
        non-recourse debt of EWG/FUCO Projects, to the extent normally
        consolidated under applicable financial reporting rules).

d.)     As permitted by the Merger U-1, AmerGen receives services from ComEd and
        PECO including engineering, regulatory support, systems integration,
        accounting and general services. These services are performed at cost,
        pursuant to the Affiliate Interests Agreement in the case of ComEd and
        pursuant to the Mutual Services Agreement in the case of PECO, and it is
        expected that each company wil provide AmerGen with approximately
        $300,000 in services annually. In addition, Exelon Generation Company
        LLC will provide AmerGen with similar services valued at approximately
        $49,900,000, at cost, pursuant to a contract being drafted.

Part II

        An organization chart showing the relationship of each EWG to other
        system companies is included as Exhibit H. (filed herewith on Form SE)


Part III

As determined pursuant to the December 8, 2000 Order, the Modified Rule 53 Test
applicable to Exelon's investments in EWGs and FUCOs issued in connection with
the Financing U-1, is $4,000.0 million. At December 31, 2000, Exelon's
"aggregate investment" (as defined in rule 53(a) under PUHCA) in all EWGs and
FUCOs was approximately $748.0 million, and accordingly, at December 31, 2000,
Exelon's remaining investment capacity under the Modified Rule 53 Test was
approximately $3,252.0 million.
