                   ARVP II ACQUISITION, L.P. EXTENDS OFFER FOR
        AMERICAN RETIREMENT VILLAS PROPERTIES II UNTIL SEPTEMBER 10, 2004



COSTA MESA, C.A. - (BUSINESS WIRE) - August 27, 2004 - ARVP II Acquisition, L.P.
(the "Purchaser") announced today that it has extended the expiration date of
its tender offer to purchase all of the limited partnership units (other than
units owned by ARV Assisted Living, Inc. or its affiliates) of American
Retirement Villas Properties II, a California limited partnership, (the
"Partnership") for $400 per unit in cash, less the amount of any cash
distributions made or declared with respect to the units on or after March 24,
2004, in accordance with the terms of the Purchaser's Offer to Purchase and
Consent Solicitation Statement, dated March 24, 2004 (the "Offer to Purchase").
The offer has been extended to 11:59 p.m. Eastern time, on September 10, 2004,
unless further extended (the "Expiration Date"). If the offer is further
extended, the Purchaser will issue a press release no later than 9:00 a.m.,
Eastern time, on the next business day after the day on which the offer and
consent solicitation were previously scheduled to expire. Unitholders who have
already validly tendered their units will receive $400 per unit in accordance
with the Offer to Purchase, unless they withdraw their units in accordance with
the Offer to Purchase. As of the close of business on August 26, 2004,
approximately 9,300.921 units, or approximately 55.70% of all outstanding units
(other than units held by ARV Assisted Living, Inc. or its affiliates) had been
validly tendered and not withdrawn.



The Purchaser is offering to purchase all the units (other than units held by
ARV Assisted Living, Inc. or its affiliates) at a price of $400 per unit in
cash, less the amount of any cash distributions made or declared with respect to
the units on or after March 24, 2004, in accordance with the terms of the Offer
to Purchase. ARV Assisted Living, Inc., the general partner of the Partnership,
directly or indirectly wholly-owns the Purchaser, and is a wholly-owned
subsidiary of Atria Senior Living Group, Inc. ARV Assisted Living, Inc. also
owns approximately 52.5% of the limited partnership units of the Partnership. As
of the close of business on August 26, 2004, approximately 9,300.921 units, or
approximately 55.70% of all outstanding units (other than units held by ARV
Assisted Living, Inc. or its affiliates) had been validly tendered and not
withdrawn.



In connection with the fairness hearing held on August 25, 2004 before the
California Corporations Commissioner regarding the proposed merger of the
Purchaser with and into the Partnership described in the Offer to Purchase, the
Purchaser provided an updated analysis of its estimated liquidation value per
unit in response to a query from an interested limited partner. Utilizing the
same assumptions and methodology in the Offer to Purchase, and based upon the
Partnership's most recently reported unaudited financial information from the
Partnership's Form 10-Q for the quarter ended June 30, 2004 filed with the
Securities and Exchange Commission on August 16, 2004, the Purchaser estimates
the liquidation value per unit to be $374.17, as shown below:

1    Consists of cash ($4,510,000) and net working capital ($540,000) as of June
     30, 2004. Net working capital is defined as current assets less current
     liabilities.





As shown above, the Offer Price of $400 continues to represent a premium to the
Purchaser's estimate of the liquidation value per Partnership unit of $374.14.
The Offer Price also exceeds the prices paid in the most recent secondary market
sales transactions reported to the Partnership and effective in January,
February and April, 2004, in which units were purchased at a price of $325 per
Unit, less the $150 transfer fee payable by the seller.


At the conclusion of the fairness hearing, the hearing officer stated that he
would take under consideration the request for approval of the proposed merger
as well as the documents and information submitted into the record with respect
to the transaction, and that he expected to issue a decision on whether to issue
a permit approving the proposed merger on behalf of the California Corporations
Commissioner within 10 to 14 days.



As announced by the Purchaser on August 13, 2004, as of the close of business on
Thursday, August 12, 2004, a total of 8387.8 units, or approximately 50.23% of
all outstanding units (other than units owned by ARV or its affiliates) had been
voted in favor of the proposed merger. As a result of the Purchaser's receipt of
sufficient consents approving the proposed merger, all votes previously
delivered in the consent solicitation have become effective and may not be
changed. Accordingly, unitholders are not required to take any further action
with respect to the consent solicitation.
