Dear Limited Partner:

     We are continuing to offer to purchase units in your Partnership, Riverside
Park Associates Limited Partnership for $38,250 per unit. Subject to the terms
of the offer, we are offering to purchase any and all of the units in your
partnership. Our offer price is $250 HIGHER than the price that has recently
been offered by any unaffiliated third parties. IF IT IS LIQUIDITY YOU DESIRE,
OUR OFFER PROVIDES YOU WITH THE GREATEST PURCHASE PRICE CURRENTLY BEING OFFERED.

     We are offering to purchase more Units than the unaffiliated third parties
are currently offering to purchase. OUR OFFER PROVIDES YOU WITH THE GREATEST
CHANCE TO RECEIVE THE HIGHEST PURCHASE PRICE CURRENTLY BEING OFFERED FOR THE
GREATEST NUMBER OF UNITS.

     There are advantages and disadvantages to you of accepting or declining our
offer. The terms of the offer are more fully described in the Offer to Purchase,
dated May 15, 2000, a Supplement, dated June 14, 2000 and the enclosed
Supplement, dated June 23, which you should read carefully. These documents
describe the material risks and opportunities associated with the offer,
including certain tax considerations. The general partner of the Partnership is
our affiliate. The general partner of your partnership makes no recommendation
as to whether you

should tender or refrain from tendering your units in any offer. Although the
general partner believes the offer of AIMCO Properties, L.P. is fair, the
general partner also believes that you must make your own decision whether or
not to participate in any offer, based upon a number of factors, including
several factors that may be personal to you, such as your financial position,
your need or desire for liquidity, your preferences regarding the timing of when
you might wish to sell your units, other financial opportunities available to
you, and your tax position and the tax consequences to you of selling your
units. However, the general partner notes that the our offer is currently at the
highest price of the offers and if you wish to sell your units for cash, you
should do so at the highest price. Therefore, the general partner recommends
against tendering in the unaffiliated third parties' offer. LIMITED PARTNERS ARE
URGED TO READ OUR OFFER TO PURCHASE, THE SUPPLEMENT AND THE RELATED MATERIALS
CAREFULLY AND IN THEIR ENTIRETY BEFORE DECIDING WHETHER TO TENDER THEIR UNITS.

     You should be aware, however, that, as with any rational investment
decision, we are making our offer with a view to making a profit.

     Our offer will expire on July 10, 2000, unless otherwise extended. If you
have not already sent in your Letter of Transmittal to accept our offer, please
remember, the enclosed letter of Transmittal must be received on or before July
10, 2000. If you have any questions concerning the terms of the offer, or need
assistance in completing the forms necessary to tender your units, please

                                                     Very truly yours,



                                                     AIMCO PROPERTIES, L.P.
