 ACADIA REALTY TRUST ANNOUNCES FINAL RESULTS OF DUTCH AUCTION TENDER OFFER FOR
   ITS SHARES AND APPROVES REQUEST OF YALE UNIVERSITY TO PURCHASE 2.3 MILLION
                       SHARES FROM INSTITUTIONAL INVESTOR

New York, NY (February 7, 2002) - Acadia Realty Trust (NYSE: AKR), a fully
integrated shopping center and real estate investment trust, today announced the
final results of its modified Dutch auction tender offer, which expired at 11:59
P.M. Eastern Time on February 1, 2002.

Consistent with the preliminary results announced February 4, 2002, Acadia will
purchase all of the 5,523,974 shares properly tendered at a purchase price of
$6.05 per share and not withdrawn prior to expiration of the offer. The
5,523,974 shares to be purchased are comprised of the 5,384,615 shares Acadia
offered to purchase and 139,359 shares to be purchased pursuant to Acadia's
right to purchase up to an additional 2% of its shares outstanding. Due to the
exercise of such right, there will be no proration and all shares tendered at
$6.05 per share will be purchased. For this purpose, shares tendered at $6.05
include shares tendered by those shareholders who indicated in their letter of
transmittal that they were willing to accept the price determined in the offer.
An additional 1,986,773 shares were tendered at prices greater than $6.05 and as
a result, will not be purchased by the Company. All shares purchased in the
offer will receive the same price. Following the purchase of the shares tendered
in the tender offer, Acadia will have 24,955,349 common shares and 3,468,059
common units of limited partnership interest convertible into common shares
outstanding. The aggregate purchase price being paid for the 5,523,974 shares
will be $33,420,043.

Payment for shares accepted for purchase, and the return of all other shares
tendered but not accepted for payment, will be made promptly by American Stock
Transfer & Trust Company, the depositary for the tender offer.

Acadia also announced that the Board of Trustees has voted to permit Yale
University, which currently owns 6,155,092 common shares of the Company, to
acquire 2,266,667 additional common shares from the Howard Hughes Medical
Institute by granting a conditional waiver of the provision in Acadia's
Declaration of Trust that prohibits ownership positions in excess of 4% of the
Company. The waiver is limited to this particular transaction. Additionally, as
a condition to approving the waiver, Acadia's Board and Yale University agreed
to establish a voting trust whereby all shares that Yale University owns in
excess of 30% of the Company's outstanding common shares, will be voted in the
same proportion as all other shares voted, excluding Yale. Following its
acquisition of the 2,266,667 additional common shares and after giving effect to
the reduction in outstanding common shares as a result of the tender offer, Yale
University's ownership would increase to 33.8% of Acadia's outstanding common
shares.
