                          EDISON MISSION HOLDINGS CO.

     SOLICITATION OF CONSENTS TO AMENDMENTS AND WAIVERS WITH RESPECT TO THE
      INDENTURE GOVERNING ITS 8.137% SENIOR SECURED BONDS DUE 2019 AND ITS
                      8.734% SENIOR SECURED BONDS DUE 2026

                                                               November __, 2001

To Brokers, Dealers, Commercial Banks,
  Trust Companies and Other Nominees:

    Edison Mission Holdings Co. is soliciting consents pursuant to the consent
solicitation statement, dated November __, 2001, from holders of its 8.137%
Senior Secured Bonds due 2019 and its 8.734% Senior Secured Bonds due 2026,
which we refer to collectively as the outstanding bonds, to the effectuation of
a sale-leaseback transaction and the adoption of proposed amendments, proposed
waivers and an authorization, which are all described in the consent
solicitation statement, with respect to the indenture under which the
outstanding bonds have been issued and related security documents. The term
"registered holder" as used herein means any person in whose name outstanding
bonds were registered in the register maintained by The Bank of New York (as
successor to United States Trust Company of New York), as trustee under the
indenture, as of the close of business on November 16, 2001, which we refer to
as the record date. The term "holder" as used herein means (1) a registered
holder or (2) any other person who has been authorized by proxy or in any other
manner acceptable to Edison Mission Holdings (or any other person claiming title
by or through such person) to vote the outstanding bonds on behalf of a
registered holder.

    Only holders may consent by executing and delivering a consent form, and
this consent will be binding on all subsequent transferees of the outstanding
bonds. The Depositary Trust Company, which we refer to as DTC, has authorized
its participants who held the outstanding bonds through DTC as of the record
date to deliver a consent form. Accordingly, for purposes of the consent
solicitation, the term "holder" shall be deemed to include participants in the
DTC system. In order to cause a consent to be given with respect to outstanding
bonds held through DTC, a DTC participant must complete and sign the consent
form, and mail or deliver it to The Bank of New York, c/o United States Trust
Company of New York, as trustee, at its address set forth on the back cover
page of the consent solicitation statement pursuant to the procedures set forth
in the consent solicitation statement. A beneficial owner of an interest in
outstanding bonds held through a DTC participant must complete and sign a letter
of instructions and deliver it to the DTC participant in order to cause a
consent to be given with respect to such outstanding bonds.

    Edison Mission Holdings will make to holders whose properly executed and
completed (and not revoked) consent forms (which include a consent) are received
by trustee at or before 5:00 p.m., New York City time, on December __, 2001,
unless the applicable expiration date is extended as provided in the consent
solicitation statement, a cash payment of U.S $     per U.S.$1,000 principal
amount of the bonds in respect of which consent has been validly given, which we
refer to as the consent payment. Consents may be revoked at any time up to the
consent date, which is the earlier of (A) 5:00 p.m. New York City time on
December __, 2001 and (B) the time on which Edison Mission Holdings receives the
requisite consents. Although the amended and restated indenture will become
effective upon its execution and delivery by Homer City Funding and the trustee,
the proposed amendments will not become operative unless and until the
sale-leaseback transaction is consummated. Holders who do not consent or who
consent after the expiration date will be subject to the amended and restated
indenture and their outstanding bonds will be replaced with pass-through bonds,
(assuming it is approved by holders of at least a majority of all outstanding
bonds and the sale-leaseback transaction is consummated) but will not receive
the consent payment.
