          WHEREAS, Commonwealth Edison Company, an Illinois corporation (the

          WHEREAS, the ESIP was amended and restated, effective January 1, 1995;
and

          WHEREAS, the Company desires to amend the Plan to reflect certain
changes in the ESIP definitions made by such amendment and restatement and to
provide additional deferrals equal to the amount that would have been credited
to a Participant's Before-Tax Contributions Accounts pursuant to 
<PAGE>
 
Section 8.1(f) the ESIP on account of dividends distributed to such Participant
but for the Dollar Limit or the Before-Tax Contribution Limit.

          NOW, THEREFORE, pursuant to the power of amendment contained in
Section 8 of the Plan, the Plan is hereby amended, effective as of January 1,
1995, as follows:

      1.  All references in the Plan to the term "Compensation Conversion
Account" shall be amended to the term "Before-Tax Contributions Account."

      (b) Section 4.2 of the ESIP, relating to the dollar limit;

      (c) Section 4.4 of the ESIP, relating to the Before-Tax Contribution Limit

          Each such election shall be deemed to authorize the Participant's
          compensation by an amount equal to the amount that would have been
          credited to the Participant's Before-Tax Contributions Account
          pursuant to the deemed election contained in the fourth sentence of
          Section 3.2 of the ESIP (providing for additional Before-Tax
          Contributions equal to dividends distributed to the Participant
          pursuant to Section 8.1(f) of the ESIP) but for the provisions
          described in clauses (a), (b), (c) and (d) of the preceding sentence.
