DEAR EL PASO STOCKHOLDER:

     Thank you for  returning  your WHITE  proxy for the Annual  Meeting of
Stockholders of El Paso Corporation  scheduled to be held on June 17, 2003.
We are assisting the El Paso board of directors  (the "Board of Directors")
with the solicitation of proxies from its stockholders.

     To avoid the possibility of your vote being challenged or disqualified
for the reason(s)  indicated below, we ask that you sign, date and mail the
enclosed  new  WHITE  proxy in the  postage-paid  envelope  provided.  As a
reminder,  you are urged to vote for your Board's  nominees,  to reject the
Zilkha/Wyatt  proposals  and to NOT sign any blue  proxy they may send you.

     |_|  The proxy you previously  returned was undated.  (Please date the
          enclosed proxy, and sign it with the name shown on the proxy.)

     |_|  The  proxy  you  previously   returned  was  not  signed  by  all
          registered  owners. (If shares are registered in the name of more
          than one person, each person should sign the proxy. If shares are
          held by joint  owners and one is  deceased,  the  enclosed  proxy
          should be signed by the  remaining  joint  owner(s),  who  should
          indicate that they are the surviving  joint  owner(s).  If two or
          more owners hold shares as tenants-in-common and one is deceased,
          the   enclosed   proxy  should  be  signed  by  the  executor  or
          administrator of the deceased owner, and proof of the signatory's
          status as an executor or  administrator  should be returned  with
          the proxy.)

      |_| The  proxy  you  previously   returned   omitted  your  title  or
          authority.   (If  you  are   signing   as   attorney,   executor,
          administrator,   corporate  officer,   authorized  officer  of  a
          partnership,  trustee or guardian, please sign and give your full
          title on the enclosed proxy.)

      |_| The proxy you  previously  returned,  as marked,  did not clearly
          specify your voting instructions.  (Please sign, date and clearly
          mark the enclosed proxy.)

      |_| Other
               ------------------------------------------------------------
          (Please date and sign with the name shown on the enclosed proxy.)

     The Annual Meeting will be held on Tuesday,  June 17, 2003. Since time
is short, we would sincerely  appreciate your signing,  dating and promptly
mailing the enclosed WHITE proxy card today.

     If you have any  questions or need  assistance  in voting your shares,
please call us toll free at 1-800-322-2885. Thank you for your cooperation.

                                            Very truly yours,


                                            MACKENZIE PARTNERS, INC.
