         On November 17, 2003, we commenced a litigation settlement offer to
acquire all of the outstanding units of your partnership as part of a
court-approved settlement of class and derivative litigation brought on behalf
of limited partners in your partnership and others. The expiration date of our
offer as set forth in the Litigation Settlement Offer dated November 17, 2003
(the "Litigation Settlement Offer") was December 16, 2003. We have extended our
offer, and our offer and your withdrawal rights will now expire at midnight, New
York City time, on December 19, 2003 (unless we further extend the deadline).

         Our offer is made upon the terms and subject to the conditions set
forth in the Litigation Settlement Offer, this Supplement and the accompanying
Letter of Transmittal (which, together with any supplements or amendments,
collectively constitute the "Offer"). Upon the terms and subject to the
conditions set forth in the Offer, we will accept any and all units validly
tendered in response to our Offer.

         You may withdraw your tender of units pursuant to the Offer at any time
prior to December 19, 2003, including any extensions.

         You will not pay any partnership transfer fees if you tender your units
pursuant to the Offer. You will pay any other fees or costs, including any
transfer taxes.

         Our offer price will be reduced for any distributions subsequently made
or declared by your partnership prior to the expiration of our Offer.

         If you have already tendered your units in accordance with the original
letter of transmittal that was mailed with the Litigation Settlement Offer, you
need not take any further action to continue to tender your units.
