Introduction

        This Amendment No. 3 to the Issuer Tender Offer Statement on Schedule TO
relates to the tender offer by Acadia Realty Trust, a Maryland real estate
investment trust ("Acadia" or the "Company"), to purchase up to 4,784,615 of its
Common Shares of Beneficial Interest (including common units of limited
partnership interest convertible into our common shares), par value $.001 per
share ("Shares"). Acadia is offering to purchase these Shares at a price not
greater than $6.50 nor less than $6.05 per Share, net to the seller in cash,
upon the terms and subject to the conditions described in the Offer to Purchase,
dated December 20, 2001 ("Offer to Purchase"), and related Letter of
Transmittal, which, as amended or restated from time to time, together
constitute the "Offer."

        The information in the Offer to Purchase and the related Letter of
Transmittal, copies of which were previously filed with the Schedule TO as
Exhibit 99.a(1)(i) and Exhibit 99.a(1)(ii), respectively, is incorporated in
this Amendment No. 3 to Schedule TO by reference.

Item 1. Summary Term Sheet.

1.      The answer to the question "How many Shares will Acadia purchase?" in
        the "Summary" section of the Offer to Purchase is hereby amended and
        restated to replace the number "4,784,615" with the number "5,384,615."

2.      The twelfth question and related answer in the "Summary" section of the
        Offer to Purchase are hereby amended and restated to read as follows:

               Has any executive officer or trustee indicated an intention to
               tender Shares in the Offer?

               Yes. Ross Dworman, the Chairman of our Board of Trustees and
               former Chief Executive Officer, has indicated an intention to
               tender 600,000 Shares at a price determined by the modified Dutch
               auction. See Section 9.

Item 4. Terms of the Transaction.

1.      The front cover page, the "Introduction" section, Section 1, Section 5
        and Section 6 of the Offer to Purchase are hereby amended to replace,
        wherever they appear, the number "4,784,615" with the number
        "5,384,615."

2.      The language from the second sentence of the fifth paragraph until the
        end of the fifth paragraph in the "Introduction" section of the Offer to
        Purchase is hereby amended and restated to read as follows:

               The 5,384,615 Shares that we are offering to purchase represent
               approximately 18.8% of the Shares outstanding (or 15.9% if all of
               the Units were converted to Shares outstanding) as of December
               20, 2001.

3.      The second sentence of the first paragraph in Section 9 of the Offer to
        Purchase is hereby amended and restated to read as follows:

               With the exception of Ross Dworman, who has indicated an
               intention to tender 600,000 Shares at a price determined by the
               modified Dutch auction, no executive officers or trustees have
               indicated an intention to tender Shares in the Offer and no
               Shares are to be purchased from any executive officer or trustee
               in the Offer.

4.      Item 4 of the Schedule TO is hereby amended by inserting the following
        language:





               The Expiration Date of the Offer has been extended from 11:59

               Offer further.

Item 8. Interest in Securities of the Subject Company.

1.      Section 9 of the Offer to Purchase is hereby amended by inserting the
        following language immediately after the second sentence of the first
        paragraph:

               Neither we nor, to the best of our knowledge, any of our
               affiliates, trustees or executive officers, or any of the
               executive officers or trustees of our affiliates, is a party to
               any contract, arrangement, understanding or relationship with any
               other person relating, directly or indirectly, to the Offer with
               respect to the Shares (including, but not limited to, any
               contract, arrangement, understanding or relationship concerning
               the transfer or the voting of any such securities, joint
               ventures, loan or option arrangements, puts or calls, guaranties
               of loans, guaranties against loss or the giving or withholding of
               proxies, consents or authorizations).

2.      Section 9 of the Offer to Purchase is hereby amended by deleting the
        subsection captioned "Arrangement with Mr. Dworman with Respect to the
        Shares" in its entirety.

Item 10. Financial Statements.

1.      The first sentence of the subsection captioned "Summary Unaudited Pro
        Forma Financial Information" in Section 12 of the Offer to Purchase is
        hereby amended by deleting the words "and the agreement with Mr.
        Dworman."

Item 11. Additional Information.

1.      The fourth sentence of the second paragraph in Section 10 of the Offer
        to Purchase is hereby amended and restated in its entirety to read as
        follows:

               Since announcing our disposition plan, we have sold six non-core
               assets: a major mixed office/retail property in Florida, two
               large residential complexes in Maryland, one retail property in
               South Carolina and two retail properties in Pennsylvania.

2.      The third paragraph in Section 10 of the Offer to Purchase is hereby
        amended and restated in its entirety to read as follows:

               We are in various stages of the disposition process with respect
               to the remaining 22 non-core assets, including a 17 property
               portfolio currently under contract for sale which secures a
               cross-collateralized loan.

3.      The first sentence of the fourth paragraph in Section 10 of the Offer to
        Purchase is hereby deleted in its entirety.

4.      The second and third sentences of the fourth paragraph in Section 10 of
        the Offer to Purchase are hereby amended and restated in their entirety
        to read as follows:

               The sale of one of the residential complexes has generated
               considerable taxable gain, which will be partially offset by a
               taxable loss on the sale of one of the retail properties in
               Pennsylvania. We currently believe that we will be required under
               the tax laws to make a distribution in excess of our historical
               distribution of between $0.20 to $0.35 per Share.

               conditioned upon the buyer obtaining our lender's consent to the
               assumption of the existing loan secured by the properties.

6.      Section 10 of the Offer to Purchase is hereby amended by deleting the
        last bullet-point of the subsection captioned "Benefits of the Offer,"
        and by deleting the words "and our agreement to purchase Shares from Mr.
        Dworman" in the first sentence and replacing the words "and the Dworman
        share purchase" with the word "is"in the last sentence of the first
        bullet-point of the subsection captioned "Risks of the Offer."

7.      Item 11 of the Schedule TO is hereby amended by inserting the following
        language:
