thereto (“Agreement”), by entering into this Amendment No. 3 (“Amendment”) to
the Agreement:

WHEREAS, each of the Utilities is named as a defendant in litigation currently
pending in the Circuit Court of Cook County, Illinois, captioned Roberson v.
Commonwealth Edison Company, et al., Case No. 00 L 4360, filed April 20, 1999,
and Rutledge v. Commonwealth Edison Company, et al., Case No. 00 L 11290, filed
October 2, 2000, (individually or collectively the “Action(s)”), alleging
personal injury and/or property damage caused by conditions existing or having
existed at the former manufactured gas plant site bounded by Taylor Street,
Lombard Street, Harvard Avenue, and Garfield Avenue in Oak Park, Illinois, now
known as Barrie Park;

WHEREAS, the Barrie Park site is on the Site List, which is Attachment A to the
Agreement and is subject to the Agreement;

WHEREAS, without admitting any liability, the Utilities have determined that it
is in their mutual best interests to delay commencement of litigation of claims
which either Utility may bring against the other Utility arising from the
Actions, including but not limited to claims for contribution and indemnity
(“Potential Utility Claims”), or to resolve such Potential Utility Claims;

NOW THEREFORE, based on the covenants and mutual promises contained herein, it
is hereby agreed by and between each Utility, pursuant to Section 16 of the
Agreement, that the Agreement is modified as follows:
 
1. Applicability. This Amendment applies to all Potential Utility Claims of
either Utility which relate to the Actions and which have not been time barred
prior to the effective date of this Amendment.

2. Shared Costs

2.1. The cost of any settlement and the cost of any judgment entered against
either or both of the Utilities in the Actions will be Shared Costs under the
Agreement and will be subject to all of the provisions of the Agreement, except
as otherwise provided in this Amendment.

2.2 Section 2.2 of the Agreement is amended by adding the following to the end
of Section 2.2(d) prior to the semicolon: “or by Amendment No. 3.”

3. Preservation of Potential Utility Claims

3.1 Neither Utility shall commence litigation, whether by crossclaim or
counterclaim in either Action or in a separate civil action, against the other
Utility regarding Potential Utility Claims until and unless the Agreement is
terminated pursuant to Section 14 of the Agreement.

3.2 Any statute of limitation or repose is tolled for Potential Utility Claims
that either Utility may have against the other Utility until the Agreement is
terminated pursuant to Section 14 of the Agreement.

3.3 Any finding of fact, conclusion of law, determination of liability,
including any determination as to the relative fault or percent allocation of
liability, and/or judgment in either Action shall not have any effect, whether
by res judicata, collateral estoppel, or similar theories, in any proceeding
between the Utilities, including but not limited to, any arbitration under the
Agreement or in any litigation between the Utilities.
 
4. Settlement. The Utilities agree to cooperate in any efforts to settle the
Actions. The Utilities agree that they will not settle either Action without
mutual agreement between the Utilities unless the Agreement is terminated
pursuant to Section 14 of the Agreement.

5. Reservation of Rights. This Amendment shall not constitute nor be
interpreted, construed, or used as evidence of any admission of liability, law
or fact, or a waiver of any right or defense.

6. Authorization. Each of the signatories represents that he or she is fully
authorized to enter into the terms and conditions of, and to execute this
Amendment on his/her own behalf or on behalf of their respective client.

7. Counterparts. This Amendment may be executed in counterparts, each of which
shall be deemed an original but all of which together shall constitute one and
the same instrument.

8. Effective Date. This Amendment is effective as of April 20, 2001.
