                       ACADIA REALTY LIMITED PARTNERSHIP,
                              ACADIA REALTY TRUST,

                                KLAFF REALTY, LP

                                       AND

                              KLAFF REALTY, LIMITED

                                FEBRUARY 15, 2005



                            AGREEMENT OF CONTRIBUTION

                THIS AGREEMENT OF CONTRIBUTION (the "Agreement") is entered into
as of February 15, 2005 by and among Acadia Realty Limited Partnership, a
Delaware limited partnership ("Acadia"), Acadia Realty Trust, a Maryland real
estate investment trust (the "REIT"), Klaff Realty, LP, a Delaware limited
partnership, and Klaff Realty, Limited, an Illinois corporation (each a
"Contributor," and collectively, the "Contributors").

                                    RECITALS:

                A.      The Contributors are engaged in the retail management
services business (the "Retail Services Business") and desire to become limited
partners in Acadia by contributing to Acadia assets, including goodwill, related
to the Retail Services Business, as a going concern (the "Contributed
Property"), and Acadia has agreed to admit the Contributors as limited partners.

                B.      Acadia and Contributors desire to enter into the
Agreement to set forth certain additional terms and conditions upon which
Contributors will transfer the Contributed Property to Acadia.

                                    ARTICLE I

                            CONTRIBUTION OF PROPERTY

                I.1.    CONTRIBUTION AND ACQUISITION OF CONTRIBUTED PROPERTY

                Subject to the terms and conditions hereof, Contributors agree

Contributors, all of Contributors' right, title and interest in and to the

interest in Acadia with rights, preferences and privileges as set forth in the
partnership agreement of Acadia (the "Units") (the foregoing, together with all
other transactions contemplated by this Agreement being referred to herein as
the "Contribution"). The Contributors have provided, and Acadia acknowledges
receipt of, the Contributed Property as of the Closing Date. The Contribution
shall be consummated, as set forth in Article II hereof, in a transaction
intended to qualify for nonrecognition of gain to Contributors pursuant to
Section 721 of the Internal Revenue Code of 1986, as amended (the "Code").

                I.2.    CLOSING

                The closing of the transactions contemplated by this Agreement
(the "Closing") shall be deemed to have occurred on February 15, 2005 (the
"Closing Date") at the offices of Acadia, upon satisfaction or waiver of the
conditions set forth in Article VI hereof.

                I.3.    CONTRIBUTOR REPRESENTATIVE

                The Contributors hereby appoint Hersch M. Klaff as their
representative in connection with this Agreement (the "Contributor
Representative") and with respect to any



decisions to be made by Contributors under this Agreement, Acadia and the REIT
may rely exclusively on instructions from the Contributor Representative.

                                   ARTICLE II

                                 EXCHANGE AMOUNT

                II.1.   EXCHANGE AMOUNT

                (a)     Units Delivered at Closing. In exchange for the
contribution of the Contributed Property, the Contributors shall receive in the
aggregate, at the Closing, 250,000 Units. Each Contributor shall be entitled to
receive the number of Units set forth in Schedule 1 hereto.

                (b)     Distribution of Units. At the Closing, Acadia shall
issue the Units to the Contributors in accordance with written instructions
provided to Acadia by the Contributor Representative at least two business days
prior to the Closing.

                                   ARTICLE III

               REPRESENTATIONS AND WARRANTIES OF THE CONTRIBUTORS

                Contributors jointly and severally represent and warrant to
Acadia as follows:

                III.1.  ORGANIZATION AND STANDING

                Each Contributor is a limited partnership, corporation or a
limited liability company, duly formed, validly existing and in good standing
under the laws of its jurisdiction of organization and is duly qualified to do
business in each jurisdiction where the conduct of its business requires
qualification. Each Contributor has the full and unrestricted power and
authority to own, operate and lease its assets, to carry on its business as
currently conducted, to execute and deliver this Agreement, and each other
agreement, instrument or document relating hereto or contemplated hereby or
thereby (the "Other Agreements") to which it is a party and to carry out the
transactions contemplated hereby or thereby.

                III.2.  AUTHORIZATION; NO CONFLICTS

                The execution and delivery of this Agreement and the Other
Agreements by each Contributor and the performance by each Contributor of its
covenants and agreements under this Agreement and the Other Agreements have
been, or at Closing will have been, duly authorized by all necessary action on
the part of such Contributor. The execution, delivery and performance by each
Contributor of this Agreement and each Other Agreement to which such Contributor
is a party, the fulfillment of and compliance with the respective terms and
provisions hereof and thereof, and the consummation by such Contributor of the
transactions contemplated hereby and thereby, do not and will not: (a) conflict
with, or violate any provision of the organization documents of any Contributor;
(b) conflict with, or violate any provision of, any statute, law, ordinance,
regulation, rule, order, writ or injunction having applicability to any
Contributor, any of its assets or the Contributed Property; (c) conflict with,
result in any breach of, or constitute a

                                       -2-


default under the Contributed Property; (d) result in or require the creation or
imposition of or result in the acceleration of any indebtedness or of any
encumbrance of any nature upon, or with respect to, the Contributed Property;
except (in the case of clauses (b), (c) and (d) above) for such conflicts,
violations, breaches or defaults as will not have a material adverse effect on
the Contributed Property or the business or financial condition of any
Contributor or the consummation of this transaction.

                III.3.  BINDING OBLIGATIONS

                This Agreement and each Other Agreement executed and delivered
by each Contributor on or prior to the date hereof constitutes a valid and
binding obligation of such Contributor, enforceable in accordance with its
terms; and each Other Agreement to be executed by each Contributor pursuant
hereto or thereto, when executed and delivered in accordance with the provisions
hereof or thereof, shall be a valid and binding obligation of such Contributor,
enforceable in accordance with its terms.

                III.4.  NO LITIGATION

                There are no actions, suits, claims, arbitrations, proceedings
or investigations pending or, to the knowledge of any Contributor, threatened
against, affecting or involving the Contributed Property, any Contributor or its
businesses or assets, or the transactions contemplated by this Agreement, at law
or in equity, or before or by any court, arbitrator or governmental authority,
domestic or foreign, that could reasonably be expected to have a material
adverse effect on the Contributed Property or the business or financial
condition of any Contributor or to challenge or impair the ability of any
Contributor to consummate the Contribution.

                III.5.  CONTRIBUTED PROPERTY

                (a)     The Contributed Property is wholly owned by the
Contributors, free and clear of all liens and encumbrances.

                (b)     The Contributed Property is in full force and effect and
is the legal, valid and binding obligation of each of the parties thereto,
enforceable against such parties in accordance with its terms. None of the
Contributors is in default, and there exists no condition or act which with the
giving of notice or passage of time or otherwise will cause a default with
respect to the Contributed Property. Except as otherwise disclosed to Acadia, no
Fees under the Contributed Property for any period after the Closing Date shall
have been paid prior to the Closing Date. In no event, however, do the
Contributors represent, warrant, covenant or guaranty the payment of any Fees to
Acadia or the amount of any Fees that Acadia may receive in the future.

                III.6.  SECURITIES LAW MATTERS

                (a)     Each Contributor acknowledges that Acadia intends the
offer and issuance of the Units to be exempt from registration under the
Securities Act and applicable state securities laws by virtue of (i) the status
of each Contributor and each equity owner of such Contributor as an Accredited
Investor (as defined below), and (ii) Section 4(2) of the Securities

                                       -3-


Act of 1933, as amended (the "Securities Act") and/or Regulation D promulgated
under Section 4(2) of the Securities Act ("Regulation D"), and that Acadia will
rely in part upon the representations and warranties made by each Contributor in
this Agreement in making the determination that the offer and issuance of the
Units qualify for exemption under Rule 506 of Regulation D as an offer and sale
only to Accredited Investors (as defined below).

                (b)     Each Contributor, each of such Contributor's equity
owners and each other person or entity who has a right to vote upon or approve
the transactions contemplated hereby or who will receive a distribution of Units
pursuant to Section II.1(b) are "accredited investors" as defined in Regulation
501(a) under Regulation D ("Accredited Investors"). Each Contributor has
provided to Acadia a true, correct and complete copy of such Contributor's
organizational documents.

                (c)     Each Contributor and each other person or entity who
will receive a distribution of Units pursuant to Section II.1(b) will acquire
the Units for their own account and not with a view to or for sale in connection
with any "distribution" thereof within the meaning of the Securities Act.

                (d)     Each Contributor and its equity owners have sufficient
knowledge and experience in financial, tax and business matters to enable them
to evaluate the merits and risks of investment in the Units. Each Contributor
and its equity owners have the ability to bear the economic risk of acquiring
the Units. Each Contributor acknowledges that (i) the transactions contemplated
by this Agreement and the Other Agreements involve complex tax consequences for
each Contributor and its equity owners, and each Contributor and its equity
owners are relying solely on the advice of their own tax advisors in evaluating
such consequences, (ii) neither Acadia nor the REIT has made (or shall be deemed
to have made) any representations or warranties as to the tax consequences of
such transaction to any Contributor or any of its equity owners, and (iii)
references in this Agreement to the intended tax effect of the Contribution and
the other matters described herein shall not be deemed to imply any
representation by Acadia or the REIT as to a particular tax effect that may be
obtained by any Contributor or its equity owners. Each Contributor and its
equity owners remain solely responsible for all tax matters relating to each
Contributor and its equity owners.

                (e)     Each Contributor and each other person or entity who
will receive a distribution of Units pursuant to Section II.1(b) has been
supplied with, or had access to, information to which a reasonable investor
would attach significance in making an investment decision to acquire the Units
and any other information they have requested. Each Contributor and each other
person or entity who will receive a distribution of Units pursuant to Section
II.1(b) has had an opportunity to ask questions of and receive information and
answers from Acadia and the REIT concerning Acadia, the REIT, the Units, and the
common shares of beneficial interest ("Common Shares") into which the Units may
be exchanged, and to assess and evaluate any information supplied to them by
Acadia or the REIT, and all such questions have been answered and all such
information has been provided to their full satisfaction.

                (f)     Each Contributor and each other person or entity who
will receive a distribution of Units pursuant to Section II.1(b) acknowledges
that the Units are not registered

                                       -4-


under the Securities Act or any state securities laws and cannot be resold
without registration thereunder or exemption therefrom.

                                   ARTICLE IV

              REPRESENTATIONS AND WARRANTIES OF ACADIA AND THE REIT

                A.      Acadia Representations. Acadia represents and warrants
to Contributors as follows:

                IV.1.   ORGANIZATION AND STANDING

                Acadia is a limited partnership duly organized, validly existing
and in good standing under the laws of the State of Delaware and has the full
and unrestricted partnership power and authority to own, operate and lease its
assets and to carry on its business as currently conducted. Acadia is duly
qualified to conduct business as a foreign limited partnership and is in good
standing in each jurisdiction where the nature of the business conducted by
Acadia or the character of the assets owned, leased or otherwise held by it
makes any such qualification necessary, except where the failure to be so
qualified would not have a material adverse effect upon the business of Acadia
as currently conducted.

                IV.2.   AUTHORIZATION; NO CONFLICTS

                The execution, delivery and performance by Acadia of this
Agreement and each Other Agreement to which Acadia is a party, the fulfillment
of and compliance with the respective terms and provisions hereof and thereof,
and the consummation by Acadia of the transactions contemplated hereby and
thereby, do not and will not: (a) conflict with, or violate any provisions of,
the certificate of limited partnership or agreement of limited partnership of
Acadia; (b) conflict with, or violate any provision of, any statute, law,
ordinance, regulation, rule, order, writ or injunction having applicability to
Acadia or any of its assets; or (c) conflict with, result in any breach of, or
constitute a default under any agreement to which Acadia is a party or by which
it or any of its assets are bound; except (in the case of clauses (b) and (c)
above) for such conflicts, violations, breaches or defaults as will not have a
material adverse effect on the business or financial condition of Acadia or the
consummation of the Acquisition.

                IV.3.   BINDING OBLIGATIONS

                This Agreement and each Other Agreement executed and delivered
by Acadia constitutes a valid and binding obligation of Acadia, enforceable in
accordance with its terms; and each Other Agreement to be executed by Acadia
pursuant hereto or thereto, when executed and delivered in accordance with the
provisions hereof or thereof, shall be a valid and binding obligation of Acadia,
enforceable in accordance with its terms.

                IV.4.   NO LITIGATION

                There are no actions, suits, claims, arbitrations, proceedings
or investigations pending or, to the knowledge of Acadia, threatened against,
affecting or involving Acadia or its business or assets or the transactions
contemplated by this Agreement, at law or in equity, or

                                       -5-


before or by any court, arbitrator or governmental authority, domestic or
foreign, that could reasonably be expected to have a material adverse effect on
the business or financial condition of Acadia or challenge or impair the ability
of Acadia to consummate the Contribution.

                IV.5.   THE UNITS

                At the Closing, the Units to be issued to Contributors pursuant
to Article II hereof will be duly authorized for issuance by Acadia to
Contributors and upon issuance in accordance with this Agreement will be validly
issued, fully paid and non-assessable

                IV.6.   NO TAX AUDITS

                Acadia is not a party to any pending action, audit or proceeding
by any taxing authority for any assessment or collection of any federal, state
or local taxes.

                IV.7.   TAX REPORTING

                Acadia will treat the transfer of the Contributed Property to
Acadia for federal income tax purposes as a contribution that qualifies for
nonrecognition of gain pursuant to Section 721 of the Code. Acadia, however,
makes no representation or warranty that these positions will be respected.

                IV.8.   CAPITALIZATION

                As of September 30, 2004, 29,691,479 common units of limited
partnership ("Common OP Units") were issued and outstanding, of which 29,299,224
Common OP Units are held by the REIT and 392,255 Common OP Units are held by the
limited partners of Acadia. In addition, 1,580 Series A Preferred Units are
issued and outstanding with an aggregate liquidation preference of $1,580,000
and 4,000 Series B Preferred OP Units issued and outstanding with aggregate
liquidation preference of $4,000,000 and will rank pari passu with the Series B
Preferred Units.

                IV.9.   GOVERNMENTAL CONSENTS AND APPROVALS

                Acadia has obtained each and every consent, approval, permit or
order of, and has made each and every filing with, any individual, partnership,
corporation, trust or other entity, government agency or political subdivision
required to be obtained or made in connection with: (A) its execution, delivery
and performance of this Agreement and (B) its consummation of the transactions
contemplated hereby.

                IV.10.  ABSENCE OF CERTAIN CHANGES OR EVENTS; UNDISCLOSED
                        LIABILITIES AND AGREEMENTS

                Since September 30, 2004:

                (a)     there has not been any material adverse change in the
financial position or results of operations of Acadia from that reflected in the
consolidated financial statements of the REIT as of September 30, 2004, or any
material adverse change in the business, assets or

                                       -6-


prospects of Acadia (including the imposition of any material adverse regulatory
requirements or the loss of any material permits, licenses or franchises).

                (b)     there has not been any material damage, destruction or
other casualty loss with respect to property owned or leased by Acadia not
covered by insurance.

                (c)     Acadia has not conducted its business otherwise than in
the ordinary course.

                B.      REIT Representations. The REIT hereby represents and
warrants to the Contributors as follows:

                        (i)     Organization, Good Standing, Corporate Power and
        Authorization. The REIT is a real estate investment trust duly
        organized, validly existing and in good standing under the laws of the
        State of Maryland and has full right, power and authority to enter into
        this Agreement and to assume and perform all of its obligations. The
        REIT is duly qualified to conduct business as a foreign real estate
        investment trust and is in good standing in each jurisdiction where the
        nature of the business conducted by the REIT or the character of the
        assets owned, leased or otherwise held by it makes any such
        qualification necessary, except where the failure to be so qualified
        would not have a material adverse effect upon the business of the REIT
        as currently conducted. The execution and delivery of this Agreement and
        the performance by the REIT of its obligations under this Agreement will
        require no further action, consent or approval of the REIT's
        shareholders or trustees, or of any other individuals or entities in
        order to constitute this Agreement as a binding and enforceable
        obligation of the REIT.

                VIII.5. CONDITIONS OF INDEMNIFICATION

                The obligations and liabilities of Contributors and Acadia
hereunder with respect to their respective indemnities pursuant to this Article
VIII resulting from any Claim shall be subject to the following terms and
conditions:

                (a)     The indemnified party shall give prompt written notice
to the indemnifying party of any Claim which is asserted against, resulting to,
imposed upon or incurred by such indemnified party and which may give rise to
liability of the indemnifying party pursuant to this Article VIII, stating (to
the extent known or reasonably anticipated) the nature and basis of such Claim
and the amount thereof.

                (b)     If the facts pertaining to a Claim arise out of the
Claim of any third party, or if there is any Claim against a third party
available by virtue of the circumstances of the Claim, the indemnifying party
may assume the defense of such action or proceeding at such indemnifying party's
own expense with counsel chosen by the indemnifying party and approved by the
indemnified party, which approval shall not be unreasonably withheld; provided,
however, that the indemnifying party shall not agree to settlement of any such
action or proceeding which provides for any relief other than the payment of
monetary damages or which could have a material precedential impact or effect on
the business or financial condition of the indemnified party without the prior
written consent of the indemnified party; and provided,

                                      -14-


further, that if the indemnified party reasonably determines that a conflict of
interest exists where it is advisable for the indemnified party to be
represented by separate counsel or that, upon advice of counsel, there may be
legal defenses available to it which are different from or in addition to those
available to the indemnifying party, then the indemnifying party shall not be
entitled to assume such defense and the indemnified party shall be entitled to
separate counsel at the indemnifying party's expense. If the indemnifying party
is not entitled to assume the defense of such action or proceeding as a result
of the proviso to the preceding sentence, the indemnifying party's counsel shall
be entitled to conduct the indemnifying party's defense and the indemnified
party's counsel shall be entitled to conduct the indemnified party's defense, it
being understood that both such counsel will cooperate with each other to
conduct the defense of such action or proceeding as efficiently as possible. If
the indemnifying party is not so entitled to assume the defense of such action
or does not assume such defense, after having received the notice referred to in
subparagraph (a) above, the indemnifying party will pay the reasonable fees and
expenses of counsel for the indemnified party. In such event, however, the
indemnifying party will not be liable for any settlement effected without the
written consent of the indemnifying party. If an indemnifying party is entitled
to assume, and assumes, the defense of such action or proceeding in accordance
with this paragraph, the indemnifying party shall not be liable for any fees and
expenses of counsel for the indemnified party incurred thereafter in connection
with such action or proceeding. Whether or not the indemnifying party chooses to
so defend or prosecute such Claim, all the parties hereto shall cooperate in the
defense or prosecution thereof and shall furnish such records, information and
testimony, and attend such conferences, discovery proceedings, hearings, trials
and appeals, as may be reasonably requested in connection therewith. The
indemnifying party shall be subrogated to all rights and remedies of the
indemnified party.

                                      -15-


any reason, the Receiving Party shall return all such information to the
Disclosing Party. The provisions of this section shall not apply to any
information which is a matter of public record or lawfully obtainable from other
sources and shall not prevent either party from complying with applicable laws,
rules, regulations and court orders, including, without limitation, governmental
regulatory, disclosure, tax and reporting requirements. Notwithstanding the
foregoing, the parties may disclose the tax treatment and tax structure of the
transactions contemplated by this Agreement and all materials of any kind
related to such tax treatment and tax structure.

                (b)     Public Notices. Between the date hereof and for a period
ending one (1) year after the Closing Date, no party hereto shall release or
cause or permit to be released any press notices or advertising promotion or
other publicity relating to this transaction without first giving reasonable
notice to, and consulting with, each other party and, as required herein,
obtaining the written consent of each other party. No provisions in this Section
XI.1(b) shall preclude a party from discussing the substance or any relevant
details of such transactions with any of its attorneys, accountants,
professional consultants, lenders, partners, affiliates, investors, or any
prospective lender, partner or investor, as the case may be, or prevent a party
hereto, from complying with laws, rules, regulations and court orders, including
without limitation, governmental regulatory, stock exchange, disclosure, tax and
reporting requirements (including, in the case of Acadia and the REIT,
disclosure by the REIT of information that it determines is necessary or
appropriate in accordance with its obligations as a public company under rules
of the New York Stock Exchange, the Securities and Exchange Commission or other
regulatory body) or making an announcement or making any communication to its
shareholders in accordance with its corporate policy.

                X.2.    NO REPRESENTATION WITH REGARD TO TAX TREATMENT

                Notwithstanding any provision of this Agreement, no party hereto
makes any representation regarding (and shall have no liability with respect to)
the tax consequences to any other party hereto or to any of its direct or
indirect partners of the transactions contemplated herein or in any Other
Agreements.

                                   ARTICLE XI

                                  MISCELLANEOUS

                XI.1.   ADDITIONAL ACTIONS AND DOCUMENTS

                Each of the parties hereto hereby agrees to take or cause to be
taken such further actions, to execute, deliver and file or cause to be
executed, delivered and filed such further documents, and will obtain such
consents, as may be necessary or as may be reasonably requested in order to
fully effectuate the purposes, terms and conditions of this Agreement.

                XI.2.   EXPENSES

                Each party hereto shall pay its own expenses incident to this
Agreement and the transactions contemplated hereunder, including all legal and

                XI.3.   ASSIGNMENT

                No party hereto shall assign its rights and/or obligations under
this Agreement, in whole or in part, whether by operation of law or otherwise,
without the prior written consent of the other parties hereto. Notwithstanding
anything to the contrary in the preceding sentence, at any time after the
Closing Date, Acadia may assign its rights and/or obligations under this
Agreement to an affiliate, or any other person or entity in connection with a
merger, consolidation, sale or contribution of all or substantially all of its
or the REIT's assets, or other similar corporate transaction; provided, that no
assignment pursuant to the preceding clause shall release the assigning party
from its respective liabilities and obligations hereunder.

                XI.4.   ENTIRE AGREEMENT; AMENDMENT

                This Agreement, including the Exhibits and other documents
referred to herein or furnished pursuant hereto, constitute the entire agreement
among the parties hereto with respect to the transactions contemplated herein,
and supersede all prior oral or written agreements, commitments or
understandings with respect to the matters provided for herein; provided, that
nothing in this Section XI.4 shall have any effect on the Other Agreements. No
amendment, modification or discharge of this Agreement shall be valid or binding
unless set forth in writing and duly executed and delivered by the party against
whom enforcement of the amendment, modification, or discharge is sought.

                XI.5.   WAIVER

                No delay or failure on the part of any party hereto in
exercising any right, power or privilege under this Agreement or under any other
documents furnished in connection with or pursuant to this Agreement shall
impair any such right, power or privilege or be construed as a waiver of any
default or any acquiescence therein. No single or partial exercise of any such
right, power or privilege shall preclude the further exercise of such right,
power or privilege, or the exercise of any other right, power or privilege. No
waiver shall be valid against any party hereto unless made in writing and signed
by the party against whom enforcement of such waiver is sought and then only to
the extent expressly specified therein.

                XI.6.   SEVERABILITY

                If any part of any provision of this Agreement or any other
agreement or document given pursuant to or in connection with this Agreement
shall be invalid or unenforceable in any respect, such part shall be ineffective
to the extent of such invalidity or unenforceability only, without in any way
affecting the remaining parts of such provision or the remaining provisions of
this Agreement.

                XI.7.   GOVERNING LAW

                This Agreement, the rights and obligations of the parties
hereto, and any claim or disputes relating thereto, shall be governed by and
construed in accordance with the laws of the State of New York (excluding the
choice of law rules thereof).
