obligations of the Issuer contained in the exchange and registration rights
agreement in respect of the Old Bonds, dated February 15, 2000, by and among the
Issuer and the guarantors and initial purchasers referred to therein.


     We are requesting that you contact your clients for whom you hold Old Bonds

     for the information of your clients;

          3. A Notice of Guaranteed Delivery relating to the Old Bonds which is
     to be used to accept the Exchange Offer if certificates for Old Bonds are
     not immediately available or time will not permit all required documents to
     reach the Exchange Agent prior to the Expiration Date (as defined below) or
     if the procedure for book-entry transfer cannot be completed on a timely
     basis;

          4. A form of letter which may be sent to your clients for whose
     account you hold Old Bonds registered in your name or the name of your
     nominee, with space provided for obtaining such clients' instructions with

the Exchange Agent, all in accordance with the instructions set forth in the

     If a registered holder of Old Bonds desires to tender, but such Old Bonds
are not immediately available, or time will not permit such holder's Old Bonds
or other required documents to reach the Exchange Agent before the Expiration
Date, or the procedure for book-entry transfer cannot be completed on a timely
