FOR IMMEDIATE RELEASE

ARV ASSISTED LIVING, INC. AGREES TO GOING PRIVATE MERGER AT A PRICE OF $3.90 PER SHARE

COSTA MESA, CA – January 3, 2003—ARV Assisted Living, Inc. (AMEX: SRS) announced today that it has entered into a definitive merger agreement with Prometheus Assisted Living, L.L.C.

Under the terms of the transaction, ARV’s stockholders, other than Prometheus and its affiliates, will receive $3.90 per share in cash. This price reflects a premium of approximately 53% over the $2.55 closing price of the ARV common shares on September 20, 2002, the last trading day prior to the Company’s announcement on September 23, 2002 that it had received a preliminary transaction proposal from Prometheus. In addition, the price represents a premium of approximately 14% over the midpoint of the $3.25- $3.60 price range contained in Prometheus’s preliminary proposal.

The merger agreement follows the completion of a process undertaken by a Special Committee, consisting of two independent directors of ARV, to evaluate the preliminary transaction proposal received from Prometheus and consider other options available to ARV. After considering alternatives and negotiating with Prometheus, the Special Committee unanimously recommended the transaction to the Company’s full Board of Directors. Based upon that recommendation, the Company’s Board unanimously approved the transaction.

Cohen & Steers Capital Advisors LLC served as financial advisor to the Special Committee and delivered an opinion that the merger consideration of $3.90per share to be received by ARV’s stockholders, other than Prometheus and its affiliates, is fair to those stockholders from a financial point of view.

ARV will file proxy materials with the Securities and Exchange Commission for a special meeting of stockholders to vote on the proposed merger. ARV anticipates that the special meeting will be held in March 2003, subject to the timing of SEC clearance of the proxy materials.

Completion of the merger will be subject to certain closing conditions, including approval by holders of a majority of ARV’s outstanding shares and receipt of necessary regulatory approvals. Prometheus currently owns approximately 43.5 % of ARV’s outstanding shares and its affiliate holds a warrant, which if exercised, would result in Prometheus and its affiliates, together, owning approximately 45.8% of the ARV’s outstanding shares.

In a related development, ARV and Prometheus also announced today that they have reached agreements with respect to settlements of the stockholder class action lawsuits that were filed in the Delaware Court of Chancery and in the California Superior Court, Orange County, shortly after the announcement of Prometheus’ preliminary proposal. The settlements, which remain subject to court approval, are reflected in signed memoranda of understanding and are intended to resolve all claims that have or may be filed in connection with the proposed merger and related disclosures.

Prometheus has indicated that it intends, following the completion of the transaction, to combine ARV with Atria, Inc. and Kapson Senior Quarters Corp. (also assisted living companies), subject to receipt of all necessary approvals and consents. The transaction is not conditioned on this combination. The Company does not expect the transaction to have any adverse impact on residents in the Company’s assisted living communities.

ARV also announced today that the U.S. government and ARV have entered into a settlement, granting mutual releases, of all outstanding Medicare claims relating to the Company’s former GeriCare unit. Under the settlement agreement, and without admitting liability, ARV agreed to pay $1,625,000 to the U.S. government. ARV acquired GeriCare in 1996, and the Medicare certified outpatient rehabilitation provider ceased operations in 1998.

ADDITIONAL INFORMATION AND WHERE TO FIND IT.

This announcement is neither a solicitation of a proxy, an offer to purchase nor a solicitation of an offer to sell shares of ARV. In connection with the proposed transaction, ARV will file a proxy statement with the SEC.
