Acadia Realty Trust Announces it is Increasing its "Dutch Auction" Tender Offer
    to 5,384,615 Shares and Extending the Tender Offer Period to 11:59 P.M.,
                        Eastern Time on February 1, 2002

        New York, NY (January 18, 2002) - Acadia Realty Trust (NYSE: AKR), a
fully integrated shopping center and real estate investment trust, today
announced that it is extending the tender offer period for its modified Dutch
auction tender offer from 11:59 P.M. Eastern time, on January 22, 2002, until
11:59 P.M. Eastern time, on February 1, 2002.

        Acadia also announced that in lieu of a separate agreement to sell his
common shares and operating partnership units which are convertible into common
shares (in combination "Shares"), Ross Dworman, Chairman of Acadia's Board of
Directors, will tender 600,000 Shares pursuant to the terms of the tender offer
at the price determined by the modified Dutch auction. Accordingly, Acadia has
terminated the agreement for the separate purchase of up to 600,000 of Ross
Dworman's Shares and has amended the tender offer to increase by 600,000 the
number of Shares it is offering to purchase (from 4,784,615 to 5,384,615).

        Kenneth M. Bernstein, Acadia's President and Chief Executive Officer,
said "There appeared to be concern about Mr. Dworman selling his shares to the
company outside the formal tender offer. To address those concerns we have made
these changes."

        The total amount of funds required to purchase 5,384,615 Shares, the new
maximum number of Shares sought in the offer, at $6.50 per share, is $35
million. The maximum number of Shares sought is approximately 16% of the Shares
outstanding.

        Acadia commenced the tender offer on December 20, 2001, when it offered
to purchase for cash up to 4,784,615 of its Shares, subject to the terms and
conditions set forth in the Offer to Purchase dated December 20, 2001 and the
related Letter of Transmittal. The terms of the tender offer include a purchase
price for each tendered Share of not more than $6.50 nor less than $6.05 net to
the seller in cash, without interest.

        As of January 17, 2002, 2,790,000 Shares have been tendered to Acadia in
the offer (not including 600,000 Shares that Mr. Dworman will tender). On
December 19, 2001, the last trading day prior to the announcement of the tender
offer, the New York Stock Exchange closing price for Acadia common shares was
$6.26. On January 18, 2002 the closing price was $6.32 per share.

        While Acadia's Board of Trustees has approved this tender offer, neither
Acadia nor its Board of Trustees is making any recommendation to shareholders as
to whether to tender or refrain from tendering their Shares or as to the price
or prices at which they may choose to tender


their Shares. Shareholders must make their own decision as to whether to tender, how many Shares to tender and the price or prices at which such Shares should be tendered. Acadia Realty Trust, headquartered on Long Island, NY, is a self-administered equity real estate investment trust structured as an UPREIT, which specializes in the operation, management, leasing, renovation and acquisition of shopping centers properties. The Company currently owns and operates 53 properties totaling approximately 10 million square feet, primarily in the eastern half of the United States. Acadia's principal executive offices are located in Port Washington, New York, with a corporate office located in Manhattan. This press release is for informational purposes only and is not an offer to buy or the solicitation of an offer to sell any Shares.
