To Whom It May Concern:

     As you are aware, we have extended the Expiration Date of our Offer and
Consent Solicitation to 11:59 p.m. Eastern time on May 14, 2004. As a result,
your clients have until this time to tender their Units and consent to the
Merger Proposal as provided in our Offer to Purchase Offer and Consent
Solicitation Statement, dated March 24, 2004 (the "Offer to Purchase").

     Our records indicate some or all of your clients have not yet tendered
their Units or consented to our proposal to effect the Merger as provided in the
Offer to Purchase. For your convenience, we have attached to this letter a list
of the names of your clients who have not yet tendered their Units or voted on
the Merger Proposal.

     The Offer and the Merger are each conditioned on, among other things,
approval of the Merger Proposal by Unitholders holding more than 50% of the
Units that ARV Assisted Living, Inc. or its subsidiaries do not own. Therefore,
if we do not receive such approvals, your clients may not receive the $400 per
Unit Offer Price, even if they have validly tendered their Units and consented
to the Merger Proposal.

     Anyone wishing to tender their Units must complete and fax his or her
Agreement of Assignment and Transfer previously sent to such person immediately
to ACS Securities Services, Inc. at (866) 275-3710 on or prior to the Expiration
Date and mail in the originals of such materials as provided in the Offer to

     Furthermore, anyone wishing to consent to the Merger Proposal must complete

the same number on or prior to the Expiration Date.

     Unless otherwise defined herein, all capitalized terms used herein shall
have the meanings assigned to them in the Offer to Purchase.

     If you have any questions, please call the Information Agent at (866)
275-3707 or Ms. Connie Lester at (714) 435-4338.

                                          Very truly yours,

                                          ARVP III Acquisition, L.P.
