To Our Clients:

     We are enclosing for your consideration a Prospectus (the "Prospectus")

Preferred Stock") of EXCO.

     Your attention is directed to the following:

     - EXCO Shareholders will receive one transferable Right for each share of
       Common Stock of EXCO held as of the close of business on the Record Date.
       No fractional rights or cash in lieu thereof will be paid, and the number
       of Rights distributed to each holder of Common Stock will be rounded up
       to the nearest whole number of Rights.

     - Rights [will] be admitted for trading on the Nasdaq National Market, on
       which EXCO's Common Stock is traded. Assuming a market exists, Rights may
       be purchased or sold through normal brokerage channels or sold through

       "Subscription Price".)

     - Oversubscription Privilege:  Any holder of Rights who fully exercises all
       Rights held by him is entitled to subscribe at the Subscription Price for
       shares that were not otherwise subscribed for during the basic
       subscription. However, if such oversubscriptions exceed the number of
       shares available, the shares available will be allocated among those who
       oversubscribed based on the number of shares subscribed for by such
       holder pursuant to the basic subscription privilege, as more fully
       described in the Prospectus.

     - The expiration date of the rights offering is 5:00 p.m. New York time, on
                   , 2001, unless extended by EXCO.

held in your Account, we have received your transferable Rights. We will
exercise or sell your Rights only in accordance with your instructions. IF YOU
DO NOT GIVE US YOUR INSTRUCTIONS, YOUR RIGHTS WILL BECOME VALUELESS AFTER THE
EXPIRATION DATE.

     Please forward your instructions to us immediately by completing the form
on the reverse side. Your Rights will expire at 5:00 p.m. New York time,
            , 2001, unless the rights offering is extended by EXCO.
