Dear Limited Partner:

         You should have already received the tender offer documents, including
the Amended and Restated Offer to Purchase dated December 17, 2004, we recently
mailed you offering to acquire your units of limited partnership interest in
MCCOMBS REALTY PARTNERS. The offer was originally scheduled to expire on January
16, 2004. BY THIS LETTER, WE ARE NOTIFYING YOU THAT WE HAVE EXTENDED THE TENDER
OFFER UNTIL MIDNIGHT, NEW YORK TIME, ON JANUARY 30, 2004. As of January 14,
2004, 425 units, or 2.9%, had been tendered to us in response to this offer.

         Our offer provides you with an opportunity to gain liquidity for your
investment and to eliminate the cost and record keeping associated with limited
partnership tax reporting. If we purchase your tendered units, you will receive
cash, but you may recognize a gain or loss for federal income tax purposes.
However, you will not receive a K-1 in respect of your partnership income or
loss after the tax year in which your units are purchased. If you retain your
units, you will continue to be a limited partner. However, you may not be able
to liquidate your investment until the partnership terminates.

         If you have not already done so, please remember, that to accept our
offer the enclosed Amended and Restated Acknowledgement and Agreement must be
received before January 30, 2004.
