         3.       Notice of Guaranteed Delivery;

         4.       Letter that may be sent to your clients for whose accounts you
                  hold Old Notes in your name or in the name of your nominee;
                  and

         5.       Letter that may be sent from your clients to you with such
                  client's instruction with regard to the Exchange Offer.

         We urge you to contact your clients promptly. Please note that the
Exchange Offer will expire on the Expiration Date unless extended.

         The Exchange Offer is not conditioned upon any minimum number of Old

         Pursuant to the Letter of Transmittal, each holder of Old Notes will

own account in exchange for Old Notes that were acquired as a result of
market-making activities or other trading activities, it must acknowledge that
it will deliver a prospectus in connection with any resale of such New Notes.

         The enclosed Letter to Clients contains an authorization by the
beneficial owners of the Old Notes for you to make the foregoing
