                           Offer To Purchase Units in
                       Urban Improvement Fund Limited 1973
                                for $400 Per Unit

Dear Limited Partner:

Enclosed with this letter is an offer to purchase limited partnership units in
Urban Improvement Fund Limited 1973 (the "Partnership") for $400 per unit [See
"THE OFFER-Introduction"]. This offer expires on July 8, 2002. If you are
interested in selling your units, please read the enclosed offer carefully.

FACTORS TO CONSIDER IN EVALUATING THIS OFFER

o    Highest Offer Price
     When adjusted to account for the Partnership's recent liquidating
     distributions, the Purchaser's $400 per unit offer price represents a
     premium over the most recent offer to purchase units made by an affiliate
     of the general partner of the Partnership. The Purchaser's offer price is
     net to the seller and the Purchaser will pay all transfer fees associated
     with the sale of your units.

o    The Partnership is Primarily Invested in Government-Subsidized Housing
     The Partnership currently holds limited partnership interests in eleven
     limited partnerships (the "Local Partnerships"). The Local Partnerships
     primarily own low-income housing projects that are subject to government
     regulations limiting the amount of money that the Local Partnerships can
     distribute to the Partnership. Government regulations also limit the
     properties' rent levels and may limit the Local Partnerships' ability to
     refinance or sell these properties.

o    Opportunity for Liquidity
     The Lexington Fund's offer provides liquidity to limited partners and will
     give them an opportunity to liquidate this investment. The Partnership has
     been in existence for 29 years. Given the long-term nature of the leases
     encumbering the Partnership's properties, the Purchaser anticipates that
     the Partnership will continue to operate for the foreseeable future. By
     selling your limited partnership units, you give yourself the opportunity
     to place the proceeds from a sale into other, potentially better
     performing, investments. You may also simplify your tax returns by
     eliminating future K-1 reporting for this Partnership.

o    Offer Price May Not Represent the Full Value of Your Units
     No independent party has been retained by the Purchaser or any other person
     to evaluate or render any opinion to limited partners with respect to the
     fairness of the offer price, and no representation is made as to any
     fairness or other measures of value that may be relevant to limited
     partners. Because of the two-tiered nature of the Partnership, the
     government-regulated income restrictions and the potential inability to
     sell or refinance a portion of the Partnership's assets, the Purchaser was
     unable to calculate a net asset value (NAV) for units and the Purchaser's
     offer price may be viewed as speculative in nature. As a result, it is
     uncertain whether the offer price reflects the value that would be realized
     upon the sale of units by a limited partner to a third party. [See "THE
     OFFER-Section 7-Purpose and Effects of the Offer"]



o    Conflict of Interest
     The Purchaser is making the Offer with a view toward making a profit.
     Accordingly, there is a conflict between the Purchaser's desire to acquire
     your units at a low price and your desire to sell your units at a high
     price. The Purchaser's intent is to acquire the units at a discount to the
     value it might ultimately realize from owning the units.

o    Effects of a Sale of Your Units
     Limited partners who sell their units will be giving up the opportunity to
     participate in any future potential benefits associated with ownership of
     units, including the right to participate in any future distribution of
     cash or property.

The Purchaser

The Lexington Fund is in the business of acquiring fractional investment
interests for long-term retention and seeks to purchase units in the Partnership
in advancement of that strategy. The units acquired as a result of this offer
will be held as long-term investments and not with a view to a resale. The
Lexington Fund does not acquire general partner positions and is not engaged in
property management.

Please read the enclosed offer carefully. It contains important information
concerning this offer, the Partnership and the Purchaser. If you wish to sell
your units, complete the enclosed Agreement of Sale according to the directions
on the agreement, sign where indicated and return it in the pre-addressed return
envelope.
