                               PROSPECTUS SUMMARY


         This Summary only  highlights the more detailed  information  appearing
elsewhere in this prospectus or incorporated  herein by reference.  As this is a
summary, it may not contain all information that is important to you. You should
read this entire  prospectus  carefully  before deciding whether to purchase our
common shares.

                                   The Company

         We are a  fully-integrated  and  self-managed  real  estate  investment
trust. We are primarily engaged in the ownership, acquisition, redevelopment and
management of neighborhood  and community  shopping  centers,  and multi- family
properties.  We were organized in March, 1993, and until August,  1998, our name
was Mark Centers  Trust.  Our common shares trade on the New York Stock Exchange
under the symbol "AKR."

         We are formed  under the laws of the State of Maryland.  Our  principal
executive offices are located at 20 Soundview Marketplace,  Port Washington, New
York 11050. Our phone number is (516) 767-8830.

                         Securities That May Be Offered

         This prospectus  relates to the offer and sale from time to time by the
persons listed under the "Selling  Shareholders"  section of this  prospectus of
(i) up to 16,061,238 common shares and (ii) up to 10,658,081 common shares which
may be issued  upon the  exchange  of OP Units held by  certain  of the  Selling
Shareholders  including  294,933  OP  Units  issuable  upon  the  conversion  of
preferred  OP units.  We are  registering  the  common  shares  covered  by this
prospectus to satisfy our obligations under registration  rights agreements with
the Selling Shareholders.

         We will not  receive  any  cash  proceeds  from the sale of the  common
shares by the Selling Shareholders.

                                  Risk Factors

         Investing in our common shares  involves  various risks. In considering
whether to purchase our common shares, you should carefully consider the matters
discussed under "Risk Factors" beginning on page 8 of this prospectus.

                            Tax Status of the Company

         Acadia has elected to qualify as a REIT under  Sections 856 through 860
of the  Internal  Revenue  Code of 1986 in each year since  1993.  As long as we
qualify for  taxation  as a REIT,  we  generally  will not be subject to federal
income tax on that  portion of our  ordinary  income and  capital  gains that is
distributed to our  shareholders.  Even if we qualify for taxation as a REIT, we
may be subject to certain  state and local taxes on our income and  property and
to federal  income  and  excise  taxes on our  undistributed  income.  See "Risk
Factors--Risk  factors  relating to our  business as a REIT" (p.9) and  "Federal
Income Tax Considerations" (p.17) for a more detailed explanation.

         You should consider  carefully the following risk factors together with
all of the other  information  included or  incorporated  by  reference  in this
prospectus  before  you  decide to  purchase  our common  shares.  This  section
includes or refers to certain  forward-looking  statements.  You should refer to
the explanation of the  qualifications  and limitations on such  forward-looking
statements discussed on page 6 of this prospectus.

We could encounter problems as a result of our use of debt.

         We borrow money to pay for the  acquisition,  development and operation
of properties and for other general corporate purposes. Our declaration of trust
(as amended) and our bylaws do not limit the amount of indebtedness  that we may
incur. By borrowing  money, we expose ourselves to several  problems,  including
the following:

        o      inability to meet existing obligations;

        o      reduced access to additional debt; and

        o      loss of our property as a result of any default on existing debt.

         As of September  30,  1999,  Acadia had total  mortgage  debt of $308.6
million of which $249.5  million was  fixed-rate  and $59.1 million was variable
rate based upon either LIBOR or the lender's  commercial paper rate plus certain
spreads. Our mortgage indebtedness is generally nonrecourse to us. However, even
with respect to nonrecourse mortgage indebtedness,  we could be obligated to pay
our  lenders   deficiencies   resulting   from,   among  other  things,   fraud,
misapplication of funds and environmental liabilities.

         A downturn  in the  economy  could make it  difficult  for us to borrow
money on favorable terms. If we are unable to borrow, we might need to sell some
of our  assets  at  unfavorable  prices  in  order  to pay our  loans.  We could
encounter several problems, including:

        o         insufficient cash flow necessary to meet required payments of
                  principal and interest;

        o         an increase on variable interest rates on indebtedness; and

        o         the inability to refinance existing indebtedness on favorable
                  terms or at all.

Increase in market interest rates could have an adverse effect on the price of
our common shares.

         One of the factors that may  influence the prices for the common shares
in public trading markets will be the annual yield from our distributions on the
common  shares as  compared  to  yields on  certain  financial  instruments.  An
increase  in market  interest  rates  will  result in higher  yields on  certain
financial  instruments,  which could adversely  affect the market prices for our
common shares.

We may suffer an uninsured loss.

         We maintain comprehensive  liability,  fire, flood (where appropriate),
extended  coverage,  and rental loss insurance with respect our properties  with
policy specifications,  limits, and deductibles  customarily carried for similar
properties.  Certain types of losses,  however, may be either uninsurable or not
economically insurable, such as losses due to earthquakes, riots or acts of war.
Should an  uninsured  loss  occur,  we could lose both our  investments  in, and
anticipated cash flow from, a property.

The loss of a key executive officer could have an adverse effect on the company.

         Although we have entered into  employment  agreements with our Chairman
and  Chief  Executive  Officer,  Ross  Dworman  and our  President,  Kenneth  F.
Bernstein, the loss of any of their services could have an adverse effect on our
operations.

Risk factors relating to our business as a REIT:

As a real estate company, our ability to generate revenues and pay distributions
to our shareholders is affected by the risks inherent in owning real property
investments.

         We derive most of our revenue from  investments in real property.  Real
property investments are subject to different types and degrees of risk that may
reduce the value of our assets and our ability to generate revenues. The factors
that may reduce our revenues, net income and cash available for distributions to
shareholders include the following:

        o        local conditions, such as an oversupply of space or a reduction
                 in demand for real estate in an area;

        o        competition from other available space;

        o        the ability of the owner to provide adequate maintenance;

        o        insurance and variable operating costs;

        o        government regulations;

        o        changes in interest rate levels;

        o        the availability of financing;

        o        potential liability due to changes in environmental and other
                 laws; and

        o        changes in the general economic climate.

We may not be able to sell our assets if we need to do so.

         Real estate investments are relatively  illiquid,  and therefore we may
not be able to sell one or more of our  properties in order to respond  promptly
to changes in economic or other  conditions.  In addition,  the Internal Revenue
Code limits a REIT's ability to sell  properties held for fewer than four years.
Our inability to sell one or more of our properties  could harm our  performance
and ultimately our ability to make distributions to our shareholders.

We could have financial problems as a result of our tenants' financial
difficulty.

         Our  commercial  and  residential  tenants  may,  from  time  to  time,
experience downturns in their  businesses/personal  finances which may result in
their  failure to make  their  rental  payments  to us when due.  Missed  rental
payments,  in the  aggregate,  could  impair  our  funds  from  operations  and,
subsequently,  our  ability  to  make  distributions  to  our  shareholders.  In
addition,  at any time,  our tenants may seek the  protection of the  bankruptcy
laws and have their leases either rejected or terminated.  Our tenants'  failure
to affirm their leases  following  bankruptcy  could similarly  impair our funds
from operations and ability to make distributions.

Our acquisition and development of real estate could cost more than we
anticipate.

         We may acquire existing retail and multi-family  housing  properties to
the extent we can acquire these  properties on acceptable  terms. We could incur
higher than anticipated costs for improvements to these properties


909738.9
                                        9

<PAGE>



to conform them to standards established for the intended market position. Once
improved, the properties may not perform as expected.

         We also intend to pursue retail and  multi-family  housing  development
projects.  Developing  properties  generally  carries  more risk than  acquiring
existing   properties.   For  example,   development  projects  usually  require
governmental  and  other  approvals,  which  we  may  not  be  able  to  obtain.
Furthermore,   approvals   frequently   require   the   improvement   of  public
infrastructure  or other  activities  to mitigate  the  effects of the  proposed
development,  which may cost more than we anticipate. Our development activities
will also entail other risks, including:

        o         that we will devote financial and management resources to
                  projects which may not come to fruition;

        o         that we will not complete a development project as scheduled;

        o         that we will incur higher construction costs than anticipated;

        o         that occupancy rates and rents at a completed project will be
                  less than anticipated; and

        o         that expenses at a completed development will be higher than
                  anticipated.

These risks may harm our results of operations and impair our ability to make
distributions to our shareholders.

         Integrating the aforementioned  acquisition and development  properties
into our current systems and procedures  presents a challenge to our management.
Failure to do so could  cause us  financial  harm and impair our ability to make
distributions to our shareholders.

We could incur unanticipated expenses if we fail to qualify as a REIT.

         We have elected to qualify as a REIT under the Internal  Revenue  Code.
We  believe  that  since  1993  we  have   satisfied   the  REIT   qualification
requirements.  However,  the IRS  could  challenge  our REIT  qualification  for
taxable years still subject to audit. Moreover, we may fail to qualify as a REIT
in future  years.  Qualification  as a REIT involves the  application  of highly
technical and complex  Internal Revenue Code provisions for which there are only
limited judicial or  administrative  interpretations.  For example,  in order to
qualify as a REIT,  we must derive at least 95% of our gross  income in any year
from qualifying sources,  and we must distribute annually to shareholders 95% of
our REIT  taxable  income,  excluding  net  capital  gains.  In  addition,  REIT
qualification  involves the  determination of factual matters and  circumstances
not entirely within our control.

         If we were to operate in a manner that prevented us from  qualifying as
a REIT,  or if we were to fail to qualify  for any  reason,  a number of adverse
consequences  would result. If in any taxable year we fail to qualify as a REIT,
we would not be allowed to deduct distributions to shareholders in computing our
taxable  income.  Furthermore,  we would be subject to federal income tax on our
taxable income at regular corporate rates.  Unless entitled to statutory relief,
we would also be  disqualified  from  treatment  as a REIT for the four  taxable
years following the year during which  qualification was lost. As a result,  the
funds available for distribution to our  shareholders  would be reduced for each
of the years  involved.  Although we currently  intend to operate as a qualified
REIT, future economic, market, legal, tax or other considerations may impair our
REIT  qualification  or may  cause  our board of  trustees  to  revoke  the REIT
election. See "Federal Income Tax Considerations" (p.17).

We could incur costs from environmental problems even though we did not cause,
contribute to or know about them.

         Because we own, operate,  manage and develop real estate, for liability
purposes we may be considered  under the law to be an owner or operator of those
properties  or as having  arranged for the disposal or treatment of hazardous or
toxic  substances.  As a result,  we could have to pay  removal  or  remediation
costs.  Federal,  state and local  laws often  impose  liability  regardless  of
whether the owner or operator knew of, or was responsible for, the presence of

909738.9
                                       10

<PAGE>



the  hazardous or toxic  substances.  The presence of those  substances,  or the
failure to properly remediate them, may impair the owner's or operator's ability
to sell or rent the property or to borrow using the  property as  collateral.  A
person  who  arranges  for the  disposal  or  treatment  of  hazardous  or toxic
substances  may also be liable  for the costs of  removing  or  remediating  the
substances at a disposal or treatment facility,  whether or not that person owns
or operates the facility.  Furthermore,  environmental laws impose liability for
release  of  asbestos-containing  materials  into the air.  If we were ever held
responsible  for releasing  asbestos-containing  materials,  third parties could
seek  recovery from us for personal  injuries.  Thus, we might have to pay other
costs,  including  governmental fines and costs related to personal injuries and
property damage,  resulting from the environmental  condition of our properties,
regardless  of whether we actually  had  knowledge  of or  contributed  to those
conditions.

Rent control/stabilization legislation may reduce the rental income we receive
from residential properties.

         While  none  of  our  five   residential   properties  are  located  in
jurisdictions which have adopted rent  control/stabilization  legislation,  such
legislation may be enacted in these jurisdictions in the future.  Similarly,  we
may purchase  additional  properties in jurisdictions  where such legislation is
already in place. In either event, our income from  residential  leases could be
reduced, as could our ability to recover increases in operating expenses and the
costs of capital improvements.

Laws benefitting disabled persons may result in unanticipated expenses.

         A number of Federal,  state and local laws ensure that disabled persons
have  reasonable  access to public  buildings.  For  example,  the Fair  Housing
Amendments  Act of 1988 (the "FHAA")  requires that apartment  properties  first
occupied after March 13, 1990, be accessible to the  handicapped.  Noncompliance
with the FHAA could  result in an  imposition  of fines,  an award of damages to
private litigants,  and/or an order to correct any non-complying  feature (which
could result in substantial capital expenditures).  Although we believe that our
properties are  substantially  in compliance  with laws such as the FHAA, we may
incur unanticipated expenses associated with such laws.

                                   OUR COMPANY

         Our  company  (formerly  known  as  Mark  Centers  Trust)  is  a  fully
integrated   and   self-managed   REIT  focused   primarily  on  the  ownership,
acquisition, redevelopment and management of neighborhood and community shopping
centers and multi-family  properties.  All of our assets are held by, and all of
our operations are conducted through, the operating  partnership (formerly known
as Mark Centers Limited Partnership) and its majority owned partnerships.  As of
September  30,  1999,  our  company  owned  a  71%  interest  in  the  operating
partnership and the Selling  Shareholders owned the remaining 29% in the form of
OP Units,  which are exchangeable on a one-for-one  basis (subject to adjustment
for certain events) for common shares. Our company will at all times be the sole
general partner of the operating partnership.

         Our principal offices are located at 20 Soundview Marketplace, New York
11050, and our telephone number is (516) 767-8830.


                        DESCRIPTION OF OUR COMMON SHARES

         The following  description  of our common shares does not purport to be
complete and is qualified  in its  entirety by reference to our  declaration  of
trust and bylaws, each as amended and restated,  copies of which are exhibits to
the  registration  statement of which this  prospectus is a part. See "Where you
can find more information" (p.5).

General

         Under our declaration of trust, we have authority to issue  100,000,000
common shares,  par value $0.001 per share. All common shares,  when issued, are
duly authorized,  fully paid and  nonassessable.  This means that the full price
for the shares has been paid at the time of issuance and  consequently  that any
holder of such shares will not later be required to pay us any additional  money
for the same. As of September 30, 1999, 26,044,615 common shares were issued and
outstanding,  as were 10,484,143  common OP Units which are convertible into the
same number of common shares. In addition,  2,212 convertible preferred OP Units
were  issued at a price of $1,000 per Unit to certain  Selling  Shareholders  on
November 18, 1999.  These preferred OP Units,  which are convertible into common
OP Units at a  conversion  price of $7.50 per common Unit,  have a  distribution
preference and entitle the holder to a 9.0% dividend  yield.  Any OP Units which
result from the  conversion of such preferred OP Units are subject to a 12-month
lock-up  period  ending  November  16,  2000,  during  which time they cannot be
converted into common shares.


Distributions

         Common shareholders may receive distributions out of assets that we can
legally use to pay  distributions,  when and if they are authorized and declared
by our board of trustees.  Each common shareholder shares in the same proportion
as other  common  shareholders  out of the assets that we can legally use to pay
distributions after we pay or make adequate provision for all of our known debts
and  liabilities  in the event we are  liquidated,  dissolved or our affairs are
would up.

Voting Rights

         Holders  of  common  shares  have  the  power  to vote  on all  matters
presented to our  shareholders,  including  the election of trustees,  except as
otherwise  provided by Maryland law. Our  declaration of trust prohibits us from
merging or selling all or  substantially  all of our assets without the approval
of a  two-thirds  of the  outstanding  shares that are  entitled to vote on such
matters. Holders of common shares are entitled to one vote per share.



909738.9
                                       12

<PAGE>



         There is no cumulative  voting in the election of our  trustees,  which
means that holders of more than 50% of the common shares voting for the election
of  trustees  can  elect  all of the  trustees  if they  choose to do so and the
holders of the remaining shares cannot elect any trustees.

Other Rights

         All common shares have equal  dividend,  liquidation  and other rights,
and have no preference,  appraisal or exchange rights,  except for any appraisal
rights  provided  by  Maryland  Law.  Holders  of  our  common  shares  have  no
conversion, sinking fund or redemption rights, or preemptive rights to subscribe
for any of our securities.

Restrictions on Transfer

         To qualify as a REIT under the Internal  Revenue Code of 1986,  we must
satisfy certain ownership requirements. Specifically, not more than 50% in value
of our outstanding common shares may be owned,  directly or indirectly,  by five
or fewer individuals (as defined in the Internal Revenue Code of 1986 to include
certain  entities) during the last half of a taxable year, and the common shares
must be beneficially  owned by 100 or more persons during at least 335 days of a
taxable  year of  twelve  months  or  during a  proportionate  part of a shorter
taxable year. We must also satisfy  certain income  requirements to maintain our
REIT status.  One such  requirement is that at least 75% of our company's  gross
income for each  calendar  year must  consist of rents  from real  property  and
income from certain other real property investments.  This is complicated by the
fact that the rents  received by the operating  partnership  will not qualify as
rents from real property if we own, actually or  constructively,  10% or more of
the  ownership  interests  in  our  lessees,   within  the  meaning  of  section
856(d)(2)(B)  of the  Internal  Revenue Code of 1986,  as amended.  See "Federal
Income Tax Considerations--Requirements for Qualification--Income Tests" (p.19).

         Because  our  board of  trustees  believes  it is  essential  for us to
continue to qualify as a REIT,  our  declaration  of trust  contains  provisions
aimed at satisfying the requirements described above. In regard to the ownership
requirements,  the  declaration  of  trust  provides  that  subject  to  certain
exceptions,  no person may own, or be deemed to own by virtue of the attribution
provisions of the Internal Revenue Code of 1986, more than 4% of our outstanding
common   shares.   The  Trustees  may  waive  this  4%  limitation  if  evidence
satisfactory  to them or our tax counsel is presented  that such  ownership will
not jeopardize our status as a REIT. As a condition of such waiver, the Trustees
may require opinions of counsel  satisfactory to them and/or an undertaking from
the applicant with respect to preserving our REIT status.

         The trustees of Mark Centers  Trust waived the 4% ownership  limitation
in August,  1998 when certain affiliates of RD Capital,  Inc. received shares in
consideration of their contribution to Mark Center Limited  Partnership.  On two
subsequent occasions,  our trustees permitted investors owing in excess of 4% of
the trust's  outstanding shares to acquire additional shares through open market
purchases transacted during specified three-month windows.

         In addition,  our  declaration  of trust  provides  that any  purported
transfer or  issuance of shares or  securities  transferable  into shares  which
would (i) violate the 4% limitation described above, (ii) result in shares being
owned by fewer than 100  persons  for  purposes  of the REIT  provisions  of the
Internal  Revenue Code of 1986, (iii) result in Acadia being "closely held" with
the meaning of Section  856(h) of the  Internal  Revenue  Code of 1986,  or (iv)
otherwise  jeopardize our REIT status under the Internal Revenue Code (including
a transfer which would cause Acadia to own, actually or constructively,  9.8% or
more of the ownership  interests in one of our lessees) will be null and void ab
initio (from the beginning). Moreover, common shares transferred, or proposed to
be transferred, in contravention of the above will be subject to purchase by the
Acadia  at a price  equal  to the  lesser  of (i) the  price  stipulated  in the
challenged transaction and (ii) the fair market value of such shares (determined
in accordance with the rules set forth in our declaration of trust).

         All certificates representing the common shares bear a legend referring
to the restrictions described above.



909738.9
                                       13

<PAGE>



         The  ownership  limitations  described  above  could have the effect of
delaying,  deferring  or  preventing  a takeover or other  transaction  in which
holders of some,  or a majority,  of common  shares might  receive a premium for
their shares over the then  prevailing  market price or which such holders might
believe to be otherwise in their best interest.

Registration Rights

         The Selling  Shareholders and certain other holders of OP Units entered
into Registration  Rights and Lock-Up Agreements with Acadia whereby the Selling
Shareholders and OP Unit holders agreed not to sell or otherwise  transfer their
common shares and Units during a specified lockup period in exchange for certain
registration  rights.  We are filing the  registration  statement  of which this
prospectus is a part pursuant to the such agreements.

         The  Registration  Rights and Lock-Up  Agreements  provide that we will
indemnify and hold harmless the Selling  Shareholders  against  losses,  claims,
damages,   or  liabilities  (or  actions  in  respect  thereof)  to  which  such
individuals  may become  subject under Federal and state  securities  laws which
arise out of (i) any untrue  statement or alleged untrue statement of a material
fact  contained in a  registration  statement  (or any  amendment or  supplement
thereto)  pursuant  to which  their  common  shares  were  registered  under the
Securities Act of 1933, as amended, (ii) the omission or alleged omission from a
registration  statement  of a material  fact  required  to be stated  therein or
necessary  to make the  statements  therein  not  misleading,  (iii) any  untrue
statement  or alleged  untrue  statement  of a material  fact  contained  in any
prospectus,  or (iv)  the  omission  or  alleged  omission  from a  registration
statement of a material fact necessary in order to make the statements  therein,
in the light of the  circumstances  under which they were made, not  misleading.
The  Registration  Rights  and  Lock-Up  Agreements  also  provide  that we will
reimburse certain of the Selling  Shareholders  (and the officers,  directors or
controlling  persons of those Selling  Shareholders)  for any legal or any other
expenses   reasonably   incurred  by  such   individuals   in  connection   with
investigating or defending any such loss, claim, damage, liability or action.

         However,  the  indemnity  discussed  above  does not apply to a Selling
Shareholder if the loss, claim, damage or liability arises out of (i) any untrue
statement or omission made by Acadia in a  registration  statement,  preliminary
prospectus  or prospectus  (or any amendment or supplement  thereto) in reliance
upon,  and in  conformity  with,  written  information  furnished to Acadia by a
Selling  Shareholder  specifically  for  use in,  or the  preparation  of,  such
registration  statement,  preliminary prospectus or prospectus (or any amendment
or supplement thereto), or (ii) such Selling Shareholder's failure to deliver an
amended or  supplemental  prospectus,  after having been provided  copies of any
such amended or  supplemental  prospectus  by Acadia,  if such loss,  liability,
claim, damage or expense would not have arisen had such delivery occurred.

Transfer Agent and Registrar

         The  transfer  agent and  registrar  for our common  shares is American
Stock Transfer & Trust Company with has an address at 40 Wall Street,  New York,
NY 10005.

Declaration of Trust and Bylaw Provisions and Certain Provisions of Maryland Law

         Number of  Trustees;  Election of Trustees,  Removal of  Trustees,  the
Filling  of  Vacancies.  Our  declaration  of trust  provides  that the board of
trustees  will consist of not less than two nor more than fifteen  persons,  and
that the number of  trustees  will be set by the  trustees  then in office.  Our
board  currently  consists of six  trustees,  each of whom serves until the next
annual  meeting of  shareholders  and until his  successor  is duly  elected and
qualified.  Election of each trustee requires the approval of a plurality of the
votes cast by the  holders of common  shares in person or by proxy at our annual
meeting. The board of trustees does not have a nominating committee.  Our bylaws
provide that the  shareholders  may, at any time,  remove any  trustee,  with or
without cause, by the  affirmative  vote of a majority of all the votes entitled
to be cast on the matter and may elect a successor to fill any resulting vacancy
for the balance of the term of the removed  trustee.  Any vacancy  (including  a
vacancy created by an increase in the number of trustees) will be filled, at any
regular meeting or at any special meeting called for that purpose, by a majority
of the trustees.

         Limitation of Liability and  Indemnification  of Trustees and Officers.
Our  bylaws  and  declaration  of trust  authorize  our  company,  to the extent
permitted  under  Maryland  law, to indemnify its trustees and officers in their
capacity as such.  Section  8-301(15) of the Maryland  General  Corporation  Law
("MGCL")  permits a Maryland  REIT to indemnify or advance  expenses to trustees
and officers to the same extent as is permitted  for directors and officers of a
Maryland  corporation  under the MGCL The MGCL  requires a Maryland  corporation
(unless its charter provides otherwise, which our declaration of trust does not)
to  indemnify a director or officer  who has been  successful,  on the merits or
otherwise,  in the  defense  of any  proceeding  to  which he is made a party by
reason of his service in that capacity.  The MGCL permits a Maryland corporation
to  indemnify  its present and former  directors  and  officers,  among  others,
against  judgments,   penalties,  fines,  settlements  and  reasonable  expenses
actually incurred by them in connection with any proceeding to which they may be
made a party by reason of their service in those or other  capacities  unless it
is  established  that (a) the act or  omission  of the  director  or officer was
material to the matter  giving rise to the  proceeding  and (i) was committed in
bad faith or (ii) was the result of active and  deliberate  dishonesty,  (b) the
director or officer  actually  received an improper  personal  benefit in money,
property or services or (c) in the case of any criminal proceeding, the director
or  officer  had  reasonable  cause  to  believe  that the act or  omission  was
unlawful.  However,  a Maryland  corporation  may not  indemnify  for an adverse
judgment  in a suit by or in the right of the  corporation  or for a judgment of
liability on the basis that a personal benefit was improperly  received,  unless
in either case a court orders  indemnification  and then only for  expenses.  In
addition,  the MGCL permits a corporation  to advance  reasonable  expenses to a
director or officer upon the corporation's  receipt of a written  affirmation by
the  director or officer of his or her good faith  belief that he or she has met
the standard of conduct necessary for  indemnification  by the corporation and a
written  undertaking  by such  director or officer on his or her behalf to repay
the amount paid or  reimbursed  by the  corporation  if it shall  ultimately  be
determined that the standard of conduct was not met.

         Our bylaws also permit the  company,  subject the approval of our board
of  trustees,  to indemnify  and advance  expenses to any person who served as a
predecessor of the company in any of the capacities  described  above and to any
employee or agent of the company or a predecessor of the company.

         In addition  to the above,  our company  has  purchased  and  maintains
insurance  on behalf  of all of its  trustees  and  executive  officers  against
liability asserted against or incurred by them in their official capacities with
the  company,  whether  or not the  company  is  required  or has the  power  to
indemnify them against the same liability.

         Business Combinations. Section 8-301(14) of the MGCL permits a Maryland
REIT to enter to a  business  combination  (including  a merger,  consolidation,
share  exchange or, in certain  circumstances,  an asset transfer or issuance or
reclassification  of  equity  securities)  on  the  same  terms  as  a  Maryland
corporation  under the  MGCL.  Under the  MGCL,  certain  business  combinations
between a Maryland  corporation and any person who beneficially owns 10% or more
of the  voting  power of such  corporation's  shares,  or an  affiliate  of such
corporation  who, at any time within the  two-year  period  prior to the date in
question,  was the  beneficial  owner of 10% or more of the voting  power of the
then-outstanding voting shares of such corporation (an "Interested Stockholder")
or an affiliate  thereof,  are  prohibited  for five years after the most recent
date on which the  Interested  Stockholder  becomes an  Interested  Stockholder.
Thereafter,  any such business  combination  must be recommended by the board of
directors of such  corporation and approved by the affirmative  vote of at least
(a) 80% of the votes  entitled  to be cast by holders of  outstanding  shares of
voting stock of such  corporation and (b) two-thirds of the votes entitled to be
cast by holders  of shares of voting  stock of such  corporation  other than the
shares held by the Interested  Stockholder  with whom (or with whose  affiliate)
the business combination is to be affected,  unless, among other conditions, the
corporation's  common  shareholders  receive a minimum  price (as defined in the
MGCL) for their shares and the  consideration is received in cash or in the same
form as previously paid by the Interested Stockholder for its shares.

         Control Share Acquisitions.  The MGCL provides that "control shares" of
a Maryland  corporation acquired in a "control share acquisition" have no voting
rights  except  to the  extent  approved  by a vote of  two-thirds  of the votes
entitled to be cast on the matter,  excluding  shares owned by the acquirer,  by
officers or by directors who are employees of the corporation.  "Control Shares"
are voting shares of stock which,  if  aggregated  with all other such shares of
stock previously  acquired by the acquirer,  or in respect of which the acquirer
is able to exercise or direct the  exercise of voting  power  (except  solely by
virtue of a revocable proxy), would entitle the acquirer to exercise

909738.9
                                       15

<PAGE>



voting power in electing  directors within one of the following ranges of voting
power: (i) one-fifth or more but less than one-third, (ii) one-third or more but
less than a majority,  or (iii) a majority or more of all voting power.  Control
Shares do not include shares which the acquiring person is then entitled to vote
as a result of having previously obtained stockholder approval. A "control share
acquisition"  means the  acquisition  of  control  shares,  subject  to  certain
exceptions.

         A person who has made or proposes to make a control share  acquisition,
upon  satisfaction  of  certain  conditions  (including  an  undertaking  to pay
expenses),  may  compel  the board of  directors  of the  corporation  to call a
special  meeting of stockholders to be held within 50 days of demand to consider
the  voting  rights of the  shares.  If no request  for a meeting  is made,  the
corporation may itself present the question at any stockholders meeting.

         If voting  rights are not  approved at the meeting or if the  acquiring
person  does not  deliver an  acquiring  person  statement  as  required  by the
statute,  then, subject to certain  conditions and limitations,  the corporation
may redeem  any or all of the  control  shares  (except  those for which  voting
rights have previously been approved) for fair value determined,  without regard
to the absence of voting  rights for the control  shares,  as of the date of the
last control share acquisition by the acquirer or of any meeting of stockholders
at which the voting rights of such shares are  considered  and not approved.  If
voting rights for control shares are approved at a stockholders  meeting and the
acquirer becomes entitled to vote a majority of the shares entitled to vote, all
other  stockholders may exercise  appraisal rights. The fair value of the shares
as  determined  for purposes of such  appraisal  rights may not be less than the
highest price per share paid by the acquirer in the control  share  acquisition,
and certain limitations and restrictions otherwise applicable to the exercise of
dissenters' rights do not apply in the context of a control share acquisition.

         The  foregoing  does  not  apply  to  shares   acquired  in  a  merger,
consolidation  or  share  exchange,  if  the  corporation  is  a  party  to  the
transaction, or to acquisitions approved or exempted by the charter or bylaws of
the  corporation.  Pursuant to the MGCL, the company has exempted  control share
acquisitions  involving  trustees  and  employees  of the company and any person
approved by the trustees of the company in their sole discretion.

         Amendments to Our Declaration of Trust. In general,  the declaration of
trust may be amended by the  affirmative  vote or written consent of the holders
of not less than a majority of the common shares then  outstanding  and entitled
to vote thereon. However, amendments with respect to certain provisions relating
to  the  ownership   requirements,   reorganizations   and  certain  mergers  or
consolidations or the sale of substantially  all of the company's assets,  which
amendments require the affirmative vote or written consent of the holders of not
less than two-thirds of the common shares then  outstanding and entitled to vote
thereon.  The  Trustees of our  company,  by a  two-thirds  vote,  may amend the
provisions  of the  declaration  of trust from time to time to effect any change
deemed  necessary  by the  Trustees to allow  Acadia to qualify and  continue to
qualify as a REIT

         Dissolution of Our Company or its REIT Status. The declaration of trust
permits  the  termination  and  the  discontinuation  of our  operations  by the
affirmative  vote of the holders of not less than a majority of the  outstanding
shares entitled to vote at a meeting of shareholders called for that purpose. In
addition,  the  declaration  of trust permits the Trustees to terminate our REIT
status at any time.

         Anti-Takeover  Effect of Certain  Provisions of Maryland Law and of the
Declaration of Trust.  The limitation on ownership of common shares set forth in
our  declaration  of trust,  as well as the  provisions of the MGCL dealing with
business  combinations and control share  acquisitions  could have the effect of
discouraging  offers to acquire  Acadia or of hampering  the  consummation  of a
contemplated acquisition.

                     INTERESTS OF NAMED EXPERTS AND COUNSEL

         Martin L. Edelman, a trustee of the company, is counsel to the law firm
of Battle  Fowler LLP.  Battle  Fowler LLP is rendering an opinion as to certain
tax matters in the registration statement of which this prospectus is a part.


                        FEDERAL INCOME TAX CONSIDERATIONS

         The  following  is a summary of  material  federal  income tax  matters
relating to the  operations  of our company that may be relevant to  prospective
Acadia  shareholders.  It is based upon current law and is not tax advice.  This
discussion  does not address  all  aspects of  taxation  that may be relevant to
particular   shareholders   in  light  of  their  personal   investment  or  tax
circumstances,   or  to  certain  types  of  shareholders  (including,   without
limitation,    insurance   companies,   tax-exempt   organizations,    financial
institutions,  broker-dealers,  foreign  corporations  and  persons  who are not
citizens or residents of the United States)  subject to special  treatment under
the  federal  income  tax laws,  nor does it give a detailed  discussion  of any
state, local or foreign tax  considerations.  In the opinion of our tax counsel,
the   following   discussion   accurately   reflects  the  federal   income  tax
considerations  relating to the  operations of the company that are likely to be
material to an Acadia shareholder.

         EACH  PROSPECTIVE  SHAREHOLDER  OF THE COMPANY IS ENCOURAGED TO CONSULT
ITS OWN  TAX  ADVISOR  REGARDING  THE  SPECIFIC  TAX  CONSEQUENCES  TO IT OF THE
PURCHASE, OWNERSHIP AND SALE OF THE COMPANY'S COMMON SHARES AND OF THE COMPANY'S
ELECTION TO BE TAXED AS A REIT, INCLUDING THE FEDERAL, STATE, LOCAL, FOREIGN AND
OTHER TAX  CONSEQUENCES  OF SUCH PURCHASE,  OWNERSHIP,  SALE AND ELECTION AND OF
POTENTIAL CHANGES IN APPLICABLE TAX LAWS.

         General.  We made an election to be taxed as a REIT for federal  income
tax  purposes  commencing  with our taxable year ended  December  31,  1993.  We
believe the company is organized and operates in such a manner as to qualify for
taxation  as a REIT  under  the  Internal  Revenue  Code of 1986.  We  intend to
continue to operate in such a manner. However, no assurance can be given that we
will operate in a manner so as to qualify or remain qualified.

         The requirements  relating to the federal income tax treatment of REITs
and  their  shareholders  are  highly  technical  and  complex.   The  following
discussion  sets forth only the  material  aspects of those  requirements.  This
summary is qualified  in its  entirety by the  applicable  Code  provisions  and
Treasury  Regulations  promulgated  thereunder,  and administrative and judicial
interpretations thereof.

         Opinion  of Our  Tax  Counsel.  In the  opinion  of  our  tax  counsel,
commencing with the taxable year ended December 31, 1999, we have been organized
and have operated in conformity with the  requirements  for  qualification  as a
REIT within the meaning of the  Internal  Revenue  Code of 1986 and our proposed
method of operation  of the company  will enable  Acadia to continue to meet the
requirements for qualification and taxation as a REIT under the Internal Revenue
Code of 1986. It must be emphasized that the opinion of our tax counsel is based
on various assumptions and is conditioned upon certain  representations  made by
the company and others as to factual matters.  Moreover,  such qualification and
taxation as a REIT  depends  upon our  ability to meet,  through  actual  annual
operating results, the distribution levels, diversity of share ownership and the
various other  qualification  tests  imposed under the Internal  Revenue Code of
1986 that are discussed  below,  the results of which have not been and will not
be reviewed by our tax counsel.  Accordingly, no assurance can be given that the
actual results of the company's operations for any one taxable year will satisfy
such requirements.

         Taxation of Our  Company.  As long as we qualify to be taxed as a REIT,
we  generally  will not be  subject to federal  corporate  income  taxes on that
portion of its ordinary income or capital gain that is distributed  currently to
shareholders.  This is because the REIT provisions of the Internal  Revenue Code
of 1986 generally  allow a REIT to deduct  dividends  paid to its  shareholders.
This deduction for dividends paid to shareholders  substantially  eliminates the
federal  "double  taxation" on earnings  (once at the  corporate  level and once
again at the  shareholder  level) that  generally  results from  investment in a
corporation.

         Even if we qualify to be taxed as a REIT,  we may be subject to federal
income  tax in the  following  circumstances.  First,  a REIT  will be  taxed at
regular   corporate  rates  on  any   undistributed   REIT  taxable  income  and
undistributed net capital gains. Second, under certain circumstances, a REIT may
be subject to the "alternative  minimum tax" on its items of tax preference,  if
any. Third,  if a REIT has (i) net income from the sale or other  disposition of
"foreclosure property" (generally, property acquired by reason of a default on a
lease or an  indebtedness  held by a REIT)  that is held  primarily  for sale to
customers in the ordinary  course of business or (ii) other non-  qualifying net
income  from  foreclosure  property,  it will be subject  to tax at the  highest
corporate  rate  on  such  income.  Fourth,  if a REIT  has  net  income  from a
"prohibited  transaction"  (generally,  a sale or other  disposition of property
held primarily for sale to customers in the ordinary  course of business,  other
than foreclosure property), such income will be subject to a 100% tax. Fifth, if
a REIT should fail to satisfy the 75% gross  income test or the 95% gross income
test (as discussed below), and has nonetheless maintained its qualification as a
REIT because certain other  requirements  have been met, it will be subject to a
100% tax on the net income  attributable  to the  greater of the amount by which
the REIT fails the 75% or 95% test, multiplied by a fraction intended to reflect
the REIT's  profitability.  Sixth,  if a REIT  should  fail to  distribute  with
respect to each  calendar  year at least the sum of (i) 85% of its REIT ordinary
income  for such  year,  (ii) 95% of its REIT  capital  gain net income for such
year, and (iii) any  undistributed  taxable income from prior periods,  the REIT
will be subject to a 4% excise tax on the excess of such  required  distribution
over the amounts  actually  distributed.  Seventh,  if a REIT acquires any asset
from  a  C  corporation  (i.e.,  a  corporation  generally  subject  to  a  full
corporate-level  tax) in a  transaction  in which  the basis of the asset in the
REIT's hands is  determined by reference to the basis of the asset (or any other
property) in the hands of the C corporation  and the REIT recognizes gain on the
disposition  of such asset during the ten-year  period  beginning on the date on
which such asset was  acquired  by the REIT,  then the excess of the fair market
value of such property at the beginning of the applicable  ten-year  period over
the REIT's  adjusted  basis in such asset as of the  beginning of such  ten-year
period,  or built in gain,  will  generally  be subject to a tax at the  highest
regular corporate rate.

         Requirements for Qualification. To qualify as a REIT under the Internal
Revenue Code of 1986,  an  enterprise  must elect to be so treated and must meet
the  requirements,  discussed below,  relating to its  organization,  sources of
income, nature of assets, and distributions of income to shareholders.

         Organizational Requirements.  The Internal Revenue Code of 1986 defines
a REIT as a  corporation,  trust or  association:  (i) that is managed by one or
more trustees or directors;  (ii) the beneficial ownership of which is evidenced
by transferable shares or by transferable  certificates of beneficial  interest;
(iii)  that  would  be  taxable  as a  domestic  corporation  but for  the  REIT
provisions  of the  Internal  Revenue  Code of  1986;  (iv)  that is  neither  a
financial  institution nor an insurance company subject to certain provisions of
the Internal Revenue Code of 1986; (v) the beneficial ownership of which is held
by 100 or more  persons;  and (vi) during the last half of each taxable year not
more than 50% in value of the outstanding  shares owned,  directly or indirectly
through  the  application  of  certain  attribution  rules,  by  five  or  fewer
individuals (as defined in the Internal  Revenue Code of 1986 to include certain
entities).  In addition,  certain other tests,  described  below,  regarding the
nature of a REIT's income and assets, also must be satisfied.  The Code provides
that  conditions  (i)  through  (iv),  inclusive,  must be met during the entire
taxable  year and that  condition  (v) must be met during at least 335 days of a
taxable year of 12 months,  or during a proportionate  part of a taxable year of
less than 12  months.  Conditions  (v) and (vi) will not apply  until  after the
first taxable year for which an election is made to be taxed as a REIT.

         For  taxable  years  beginning  after  1997,  if a REIT  complies  with
Treasury  Regulations  that  provide  procedures  for  ascertaining  the  actual
ownership  of its  shares for such  taxable  year and the REIT did not know (and
with the exercise of reasonable  diligence  could not have known) that it failed
to meet the requirement of condition

909738.9
                                       18

<PAGE>



(vi)  above for such  taxable  year,  the REIT will be treated as having met the
requirement of condition (vi) for such year.

         We have satisfied the  requirements set forth in (i) through (iv) above
and believe that we have sufficient  diversity of share ownership to allow it to
satisfy conditions (v) and (vi) above. Our declaration of trust includes certain
restrictions  regarding  transfers of common  shares that are intended to assist
the company in satisfying the share ownership  requirements described in (v) and
(vi) above.  See  "Description of our Common  Shares--Restrictions  on Transfer"
(p.13).

         In addition,  an  enterprise  may not elect to become a REIT unless its
taxable year is the calendar year. Acadia's taxable year is the calendar year.

         In the case of a REIT that is a  partner  in a  partnership,  such REIT
will be deemed to own its  proportionate  share of the assets of the partnership
and will be deemed to be entitled to the income of the partnership  attributable
to such share. In addition,  the character of the assets and gross income of the
partnership will retain the same character in the hands of the REIT for purposes
of the REIT  requirements,  including  satisfying  the  income  and asset  tests
described herein. Thus, Acadia's proportionate share of the assets,  liabilities
and  items  of  income  of the  operating  partnership,  and  of our  subsidiary
partnerships, limited liability companies, joint ventures and business trusts in
which the company or the  operating  partnership  have and will have an interest
are and will be treated as assets, liabilities and items of income of Acadia for
purposes  of applying  the  requirements  described  herein,  provided  that the
operating   partnership   and  our  subsidiary   partnerships   are  treated  as
partnerships  for federal  income tax purposes.  See  "--Income  Taxation of the
operating partnership, the Subsidiary Partnerships and Their Partners" (p.24).

         Income Tests. In order for us to maintain  qualification  as a REIT, we
must satisfy two gross income tests  annually.  First, at least 75% of our gross
income  (excluding gross income from prohibited  transactions)  for each taxable
year must be derived  directly or indirectly from  investments  relating to real
property or mortgages on real property  (including  "rents from real  property,"
dividends from qualified REITs and, in certain circumstances,  interest) or from
"qualified temporary  investment income" (generally,  income attributable to the
temporary  investment of new capital received by the REIT). Second, at least 95%
of our gross income  (excluding gross income from prohibited  transactions)  for
each taxable year must be derived from such real property  investments  and from
dividends,  interest,  and  gain  from  the  sale or  disposition  of  stock  or
securities or from any  combination of the foregoing.  In addition,  for taxable
years prior to 1998, short-term gain from the sale or other disposition of stock
or securities,  gain from prohibited  transactions and gain on the sale or other
disposition  of real  property  held  for  less  than  four  years  (apart  from
involuntary conversions and sales of foreclosure property) must have represented
less than 30% of the gross  income of our  predecessor  (including  gross income
from prohibited transactions) for each taxable year.

         Substantially  all of our income is expected  to be rental  income from
rents.  In order for such  income to qualify as "rents from real  property"  for
purposes of  satisfying  the 75% and 95% gross  income  tests,  we must  satisfy
several  conditions.  First, the amount of rent must not be based in whole or in
part on the income or profits  of any  person,  although  rents  generally  will
qualify as rents from real  property if they are based on a fixed  percentage of
receipts  or sales.  Second,  rents  received  from a tenant will not qualify as
"rents from real  property"  if the  company,  or an owner of 10% or more of the
company, directly or constructively, owns 10% or more of such tenant (a "Related
Party  Tenant").  Third,  if rent  attributable  to personal  property leased in
connection  with a lease of real  property is greater than 15% of the total rent
received  under the lease,  the portion of rent  attributable  to such  personal
property  will not qualify as "rents from real  property."  Finally we generally
must not  operate or manage the  property  or furnish or render  services to the
tenants of such property,  other than through an "independent  contractor"  from
whom we derive no income. However, the "independent contractor" requirement does
not apply to the extent the services rendered by us are customarily furnished or
rendered in connection  with the rental of the real  property in the  geographic
area in which the property is located.  Based on our  experience we believe that
all  services  provided  to  tenants  by  us  will  be  considered  "usually  or
customarily  rendered" in connection with the rental of retail and multi- family
space,  although  there  can be no  assurance  that  the IRS  will  not  contend
otherwise.

                                       19

<PAGE>



         We believe that our real estate investments, which include an allocable
share of income  from the  operating  partnership,  will  give  rise to  income,
substantially  all of which  will  qualify  as "rents  from real  property"  for
purposes of the 75% and 95% gross income tests.  We will not (i) charge rent for
any  property  that is based in whole or in part on the income or profits of any
person  (other than being  based on a  percentage  of  receipts of sales);  (ii)
receive rents in excess of a de minimis amount from Related Party Tenants; (iii)
derive more than a de minimus amount of rents  attributable to personal property
which  constitute  greater than 15% of the total rents received under the lease;
or (iv) perform non-customary services considered to be rendered to the occupant
of property, other than through an independent contractor from whom we derive no
income.

         We may  receive  fees  in  exchange  for  the  performance  of  certain
management  activities  for third parties with respect to properties in which we
do not own an interest.  Such fees will result in nonqualifying income under the
95% and 75% gross income tests. If the sum of the income realized by us (whether
directly or through our interest in the operating  partnership or our subsidiary
partnerships)  which does not satisfy the  requirements  of the 95% gross income
test (collectively,  "Non-Qualifying Income") exceeds 5% of our gross income for
any taxable year, our status as a REIT would be jeopardized. We have represented
that the amount of  Non-Qualifying  Income in any taxable year,  including  such
fees, will not exceed 5% of our annual gross income for any taxable year.

         If we fail to satisfy one or both of the 75% or 95% gross  income tests
for any taxable year, we may nevertheless  qualify as a REIT for such year if we
are entitled to relief under certain  provisions of the Internal Revenue Code of
1986. These relief provisions  generally will be available if (i) the failure to
meet such tests was due to reasonable cause and not due to willful neglect, (ii)
a schedule of the sources of qualifying income is attached to the federal income
tax  return of the  company  for such  taxable  year,  and  (iii) any  incorrect
information on the schedule was not due to fraud with intent to evade tax. It is
not  possible,  however,  to  state  whether  in all  circumstances  we would be
entitled  to the  benefit of these  relief  provisions.  As  discussed  above in
"--Taxation of our company," even if these relief  provisions apply, a tax would
be imposed with respect to the excess net income.  No similar  relief  provision
would apply if the 30% income  test had been failed for a taxable  year prior to
1998 and, in such case,  Acadia would cease to qualify as a REIT.  See"--Failure
to Qualify" (p.21).

         Asset Tests. In order for us to qualify as a REIT, at the close of each
quarter of its taxable  year we must also  satisfy  three tests  relating to the
nature of the our assets.  First,  at least 75% of the value of its total assets
must be  represented  by real estate assets (which for this purpose  include (i)
our  allocable  share of real estate  assets held by  partnerships  in which the
company or a "qualified REIT  subsidiary"  owns an interest,  (ii) stock or debt
instruments  purchased  with the proceeds of a share offering or a long-term (at
least five  years)  debt  offering  and held for not more than one year from the
date the company receives such proceeds, and (iii) shares in qualified REITs and
cash,  cash items and government  securities.  Second,  not more than 25% of our
total assets may be represented by securities  other than those in the 75% asset
class.  Third, of the investments  included in the 25% asset class, the value of
any one issuer's  securities may not exceed 5% of the value of our total assets,
and the company may not own more than 10% of any one issuer's outstanding voting
securities  (excluding  securities  of a qualified  REIT  subsidiary  or another
REIT).

         We  anticipate  that we will be able to comply with these asset  tests.
Acadia is currently  deemed to, and will continue to be deemed to, hold directly
its  proportionate  share of all real estate and other  assets of the  operating
partnership and our subsidiary partnerships, and it should be considered to hold
its proportionate share of all assets deemed owned by those partnerships through
the partnerships' ownership of partnership interests in other partnerships. As a
result,  the company  intends to hold more than 75% of its assets as real estate
assets.  In addition,  we do not plan to hold any securities  representing  more
than 10% of any one issuer's  voting  securities,  other than any qualified REIT
subsidiary,  nor  securities of any one issuer  exceeding 5% of the value of our
gross assets.

         After initially meeting the asset tests at the close of any quarter, we
will not lose our REIT  status for failing to satisfy the asset tests at the end
of a later quarter  solely by reason of changes in asset values.  If the failure
to satisfy the asset tests  results from an  acquisition  of securities or other
property during a quarter, the failure can be cured by disposition of sufficient
nonqualifying  assets within 30 days after the close of that quarter.  We intend
to  maintain  adequate  records of the value of our assets to ensure  compliance
with the asset tests and will take such other

909738.9
                                       20

<PAGE>



action  within 30 days after the close of any quarter as may be required to cure
any  noncompliance.  However,  there can be no assurance  that such other action
always will be successful.

         Annual  Distribution  Requirements.  In order to be taxed as a REIT, we
will be required to meet certain annual distribution requirements.  We will have
to distribute  dividends (other than capital gain dividends) to our shareholders
in an  amount  at  least  equal to (1) the sum of (a) 95% of our  "REIT  taxable
income"  (computed  without  regard  to the  dividends  paid  deduction  and the
company's  net  capital  gain)  and  (b)  95% of the net  income,  if any,  from
foreclosure  property in excess of the  special  tax on income from  foreclosure
property,   minus  (2)  the  sum  of  certain  items  of  noncash  income.  Such
distributions  must be paid in the taxable year to which they relate,  or in the
following  taxable  year if  declared  before the company  timely  files its tax
return for such year and if paid on or before the first regular dividend payment
after such declaration.

         To the extent that we do not  distribute all of our net capital gain or
distribute  at least 95% (but less than  100%) of our REIT  taxable  income,  as
adjusted,  we will be subject to tax on the  undistributed  portion,  at regular
ordinary  and capital  gains  corporate  tax rates.  Furthermore,  if we fail to
distribute  for  each  calendar  year at  least  the sum of (a) 85% of our  REIT
ordinary  income for such year,  (b) 95% of our REIT capital gain net income for
such year, and (c) any undistributed ordinary income and capital gain net income
from prior periods,  we will be subject to a 4% excise tax on the excess of such
required distribution over the amounts actually  distributed.  We intend to make
timely distributions sufficient to satisfy this annual distribution requirement.

         We expect that our taxable income  typically will be less than our cash
flow,  due to the  allowance  of  depreciation  and  other  noncash  charges  in
computing our taxable income.  Accordingly, we anticipate that we generally will
have  sufficient  cash  or  liquid  assets  to  enable  it to  satisfy  the  95%
distribution requirement.

         It is possible that from time to time we may not have  sufficient  cash
or other liquid assets to meet the 95%  distribution  requirement  due to timing
differences  between  the  actual  receipt  of  income  and  actual  payment  of
deductible  expenses  and the  inclusion  of such income and  deduction  of such
expenses  in  arriving  at our  taxable  income if the  amount of  nondeductible
expenses  such as principal  amortization  or capital  expenditures  exceeds the
amount of noncash deductions.  In the event that such situation occurs, in order
to meet the 95%  distribution  requirement,  we may find it necessary to arrange
for  short-term,  or possibly  long-term,  borrowings or to pay dividends in the
form of consent  dividends.  If the  amount of  nondeductible  expenses  exceeds
noncash  deductions,  we may  refinance  our  indebtedness  to reduce  principal
payments and borrow funds for capital expenditures.

         Under certain circumstances in which an adjustment is made that affects
the amount that should have been distributed for a prior taxable year, we may be
able to rectify  the  failure to meet such  distribution  requirement  by paying
"deficiency  dividends" to shareholders in the later year, which may be included
in our deduction for dividends  paid for the earlier year.  Thus, we may be able
to avoid being taxed on amounts distributed as deficiency dividends; however, we
will be required to pay interest  based upon the amount of any  deduction  taken
for deficiency dividends.

         Failure to Qualify.  If Acadia  fails to qualify for taxation as a REIT
in any taxable year, and the relief provisions do not apply, we would be subject
to tax (including any applicable  alternative minimum tax) on our taxable income
at regular  corporate rates.  Distributions to shareholders in any year in which
we fail to qualify will not be  deductible by us nor will they be required to be
made.  In such  event,  to the  extent of current or  accumulated  earnings  and
profits,  all  distributions to shareholders will be taxable as ordinary income,
and  subject  to  certain  limitations  of the  Internal  Revenue  Code of 1986,
corporate  distributees  may be eligible for the  dividends-received  deduction.
Unless entitled to relief under specific statutory  provisions,  we also will be
disqualified  from taxation as a REIT for the four taxable  years  following the
year during which qualification was lost. It is not possible to state whether in
all circumstances we would be entitled to such statutory relief.

         Taxation  of  U.S.  Shareholders  of  the  Company.  As  used  in  this
prospectus, the term "U.S. Shareholder" means a holder of our common shares that
(for United States  federal income tax purposes) (i) is a citizen or resident of
the United States, (ii) is a corporation,  partnership,  or other entity created
or  organized  in or under the laws of the  United  States  or of any  political
subdivision thereof, (iii) is an estate the income of which is subject to United
States federal income taxation  regardless of its source or (iv) is a trust if a
United  States  court  is  able  to  exercise   primary   supervision  over  the
administration  of the  trust and one or more  United  States  persons  have the
authority to control all  substantial  decisions  of the trust.  For any taxable
year for which Acadia qualifies for taxation as a REIT,  amounts  distributed to
taxable U.S. Shareholders will be taxed as follows:

         Distributions Generally. Distributions to U.S. Shareholders, other than
capital gain dividends  discussed  below,  will be taxable as ordinary income to
such holders up to the amount of the company's  current or accumulated  earnings
and profits.  Such  distributions  are not  eligible for the  dividends-received
deduction for corporations. To the extent that the Acadia makes distributions in
excess of its current or accumulated  earnings and profits,  such  distributions
will first be treated as a tax-free return of capital, reducing the tax basis in
the  U.S.  Shareholders'  shares,  and  distributions  in  excess  of  the  U.S.
Shareholders'  tax basis in their respective shares will be taxable as an amount
realized  from the sale of such  shares.  Dividends  declared  by the company in
October, November, or December of any year payable to a shareholder of record on
a  specified  date in any such month will be treated as both paid by the company
and received by the  shareholder on December 31 of such year,  provided that the
dividend  is  actually  paid by the  company  during  January  of the  following
calendar year.  Shareholders may not include on their own income tax returns any
tax losses of the company.

         We will be treated as having  sufficient  earnings and profits to treat
as a dividend any  distribution  by the company up to the greater of our current
or accumulated  earnings and profits. As a result,  shareholders may be required
to treat certain  distributions that would otherwise result in a tax-free return
of capital as taxable  dividends.  Moreover,  any "deficiency  dividend" will be
treated as a "dividend" (an ordinary dividend or a capital gain dividend, as the
case may be), regardless of the company's earnings and profits.

         Capital  Gain  Dividends.  Dividends  to  U.S.  Shareholders  that  are
properly designated by us as capital gain dividends will be treated as long-term
capital gain (to the extent they do not exceed the company's  actual net capital
gain)  for  the  taxable  year  without  regard  to the  period  for  which  the
shareholder has held his shares. Shareholders, however, may be required to treat
up to 20% of certain  capital gain  dividends as ordinary  income.  Capital gain
dividends   are  not  eligible   for  the   dividends-received   deduction   for
corporations.

         Individual U.S. Shareholders and U.S. Shareholders that are estates and
trusts  currently  are  subject to federal  income tax on net  capital  gains at
different tax rates depending upon the nature of the gain and the holding period
of the asset  disposed  of.  Although a REIT is taxed on its  undistributed  net
capital  gains,  for taxable  years  beginning  after 1997,  a REIT may elect to
include all or a portion of such  undistributed  net capital gains in the income
of its  shareholders.  In such event,  the shareholder  will receive a credit or
refund for the amount of tax paid by the REIT on such  undistributed net capital
gains.

         Passive   Activity   and   Loss;   Investment   Interest   Limitations.
Distributions  by us and gain from the  disposition of common shares  ordinarily
will not be treated as passive activity income, and therefore, U.S. Shareholders
generally  will not be able to apply any "passive  losses"  against such income.
Dividends  from the company (to the extent  they do not  constitute  a return of
capital)  generally  will be treated as  investment  income for  purposes of the
investment interest limitation.  Net capital gain from the disposition of common
shares and capital gain  dividends  generally  will be excluded from  investment
income unless the taxpayer elects to have the gain taxed at ordinary rates.

         Dispositions of Common Shares.  A U.S.  Shareholder will recognize gain
or loss on the sale or exchange of common shares to the extent of the difference
between the amount  realized on such sale or exchange and the holder's tax basis
in such shares.  Such gain or loss generally will constitute  long-term  capital
gain or loss if the holder has held such  shares for more than one year and,  in
the case of an individual, will be taxed at a lower rate. Losses incurred on the
sale or  exchange of common  shares held for six months or less (after  applying
certain holding period

                                       22

<PAGE>



rules),  however,  generally will be deemed long-term capital loss to the extent
of any long-term  capital gain dividends  received by the U.S.  Shareholder with
respect to such shares.

         Treatment of Tax-Exempt U.S. Shareholders. The Internal Revenue Service
has ruled that amounts  distributed by a REIT out of its earnings and profits to
a tax-exempt pension trust did not constitute unrelated business taxable income.
Although  rulings  are merely  interpretations  of law by the  Internal  Revenue
Service and may be revoked or  modified,  based on this  analysis,  indebtedness
incurred by us in connection  with the  acquisition of an investment  should not
cause any income derived from the investment to be treated as unrelated business
taxable income upon the distribution of such income as dividends to a tax-exempt
entity. A tax-exempt entity that incurs  indebtedness to finance its purchase of
shares,  however, will be subject to unrelated business taxable income by virtue
of the debt-financed income rules.

         In addition,  tax-exempt  pension and certain other  tax-exempt  trusts
that hold more than 10% (by value) of the interests in a REIT may be required to
treat a percentage of REIT dividends as unrelated  business taxable income.  The
requirement  applies only if (i) the  qualification of the REIT depends upon the
application  of  a   "look-through"   exception  to  the   restriction  on  REIT
shareholdings by five or fewer  individuals,  including such trusts and (ii) the
REIT is "predominantly  held" by such trusts; i.e., either (A) at least one such
trust holds more than 25% (by value) of the  interests in the REIT or (B) one or
more such trusts  (each of whom own more than 10% by value of the  interests  in
the REIT) hold in the aggregate more than 50% (by value) of the interests in the
REIT.  It is not  anticipated  that  our REIT  qualification  will  depend  upon
application of the  "look-through"  exception or that we will be  "predominantly
held" by such trusts.

         Special  Tax  Considerations  for  Foreign   Shareholders.   The  rules
governing   United  States  federal  income  taxation  of   non-resident   alien
individuals, foreign corporations,  foreign partnerships, and foreign trusts and
estates (collectively,  "Non-U.S.  Shareholders") are complex, and the following
discussion  is intended  only as a summary of such rules.  Prospective  Non-U.S.
Shareholders  should consult with their own tax advisors to determine the impact
of federal,  state,  and local income tax laws on an  investment in the company,
including  any reporting  requirements,  as well as the tax treatment of such an
investment under their home country laws.

         In  general,  Non-U.S.  Shareholders  will be subject to United  States
federal  income tax with  respect  to their  investment  in the  company if such
investment is "effectively connected" with the Non-U.S. Shareholder's conduct of
a trade or business in the United States. A corporate  Non-U.S.  Shareholder who
receives income that is (or is treated as)  effectively  connected with a United
States  trade or  business  also may be subject to the branch  profits tax under
section 884 of the Internal Revenue Code of 1986 which is payable in addition to
United States corporate income tax. The following discussion applies to Non-U.S.
Shareholders whose investment in the company is not so effectively connected. We
expect to withhold  United States income tax, as described  below,  on the gross
amount of any distributions  paid to a Non-U.S.  Shareholder  unless (i) a lower
treaty rate  applies  and the  required  form  evidencing  eligibility  for that
reduced rate is filed with the company,  or (ii) the Non-U.S.  Shareholder files
an Internal  Revenue  Service Form 4224 or  applicable  successor  form with the
company, claiming that the distribution is "effectively connected" income.

         A distribution by us that is not  attributable to gain from the sale or
exchange  by us of a  United  States  real  property  interest  and  that is not
designated  by us as a capital  gain  dividend  will be treated  as an  ordinary
income  dividend to the extent made out of current or  accumulated  earnings and
profits.  Generally,  an ordinary  income  dividend  will be subject to a United
States  withholding  tax  equal to 30% of the gross  amount of the  distribution
unless  such tax is  reduced  or  eliminated  by an  applicable  tax  treaty.  A
distribution of cash in excess of our earnings and profits will be treated first
as a return of capital  that will reduce a Non-U.S.  Shareholder's  basis in its
holding  of our  common  shares  (but not below  zero) and then as gain from the
disposition  of such shares,  the tax treatment of which is described  under the
rules discussed below with respect to dispositions of shares.

         Distributions  by us that  are  attributable  to gain  from the sale or
exchange of a United States real  property  interest will be taxed to a Non-U.S.
Shareholder under the Foreign Investment in Real Property Tax Act of 1980. Under
the Foreign Investment in Real Property Tax Act, such distributions are taxed to
a Non-U.S. Shareholder as

909738.9
                                       23

<PAGE>



if such distributions  were gains  "effectively  connected" with a United States
trade or business.  Accordingly,  a Non- U.S.  Shareholder  will be taxed at the
normal  capital  gain rates  applicable  to a U.S.  Shareholder  (subject to any
applicable  alternative minimum tax and a special alternative minimum tax in the
case of non-resident alien  individuals).  Distributions  subject to the Foreign
Investment in Real Property Tax Act also may be subject to a 30% branch  profits
tax in the hands of a foreign  corporate  shareholder  that is not  entitled  to
treaty exemption.

         We  are   required  to   withhold   from   distributions   to  Non-U.S.
Shareholders,  and remit to the Internal Revenue Service,  (i) 35% of designated
capital gain dividends (or, if greater,  35% of the amount of any  distributions
that could be  designated  as capital gain  dividends)  and (ii) 30% of ordinary
dividends paid out of earnings and profits.  In addition,  if we designate prior
distributions  as capital gain dividends,  subsequent  distributions,  up to the
amount of such prior  distributions  not  withheld  against,  will be treated as
capital gain dividends for purposes of withholding.  A distribution in excess of
the company's earnings and profits may be subject to 30% dividend withholding if
at the time of the distribution it cannot be determined whether the distribution
will be in an amount  in  excess of our  current  or  accumulated  earnings  and
profits.  Tax treaties  may reduce our  withholding  obligations.  If the amount
withheld by us with respect to a distribution to a Non-U.S.  Shareholder exceeds
the shareholder's  United States tax liability with respect to such distribution
(as determined under the rules described in the two preceding  paragraphs),  the
Non- U.S.  Shareholder  may file for a refund of such excess  from the  Internal
Revenue Service. It should be noted that the 35% withholding tax rate on capital
gain dividends  currently  corresponds to the maximum income tax rate applicable
to  corporations,  but is higher than the 20% maximum  rate on capital  gains of
individuals.

         Unless our common  shares  constitute  a "United  States real  property
interest" within the meaning of the Foreign  Investment in Real Property Tax Act
or are  effectively  connected  with a U.S.  trade or  business,  a sale of such
shares by a Non-U.S.  Shareholder generally will not be subject to United States
taxation.  Our common  shares will not  constitute a United States real property
interest   if   the   company   is   a    "domestically-controlled    REIT."   A
domestically-controlled  REIT is a REIT in which at all times during a specified
testing  period  less  than 50% in  value  of its  shares  is held  directly  or
indirectly  by Non-U.S.  Shareholders.  It is currently  believed  that we are a
domestically-controlled  REIT,  and  therefore  that the sale of  shares  in our
company  will not be subject to taxation  under the Foreign  Investment  in Real
Property Tax Act.  However,  because the common shares are publicly  traded,  no
assurance   can  be   given   that   the   company   will   continue   to  be  a
domestically-controlled  REIT.  Notwithstanding the foregoing,  capital gain not
subject to the Foreign  Investment in Real Property Tax Act will be taxable to a
Non-U.S.  Shareholder  if  the  Non-U.S.  Shareholder  is  a  nonresident  alien
individual  who is present in the United  States for 183 days or more during the
taxable year and certain other  conditions  apply, in which case the nonresident
alien  individual  will be  subject  to a 30% tax on such  individual's  capital
gains.  If our company  did not  constitute  a  domestically-  controlled  REIT,
whether a Non-U.S. Shareholder's,  sale of common shares would be subject to tax
under the  Foreign  Investment  in Real  Property  Tax Act as a sale of a United
States real property interest would depend on whether the shares were "regularly
traded"  (as  defined by  applicable  Treasury  Regulations)  on an  established
securities market (e.g., the NYSE) and on the size of the Selling  Shareholder's
interest in the company.  If the gain on the sale of the  company's  shares were
subject to taxation  under the Foreign  Investment in Real Property Tax Act, the
Non-U.S.  Shareholder  would  be  subject  to  the  same  treatment  as  a  U.S.
Shareholder with respect to such gain (subject to applicable alternative minimum
tax and a  special  alternative  minimum  tax in the case of  nonresident  alien
individuals).  In any  event,  a  purchaser  of common  shares  from a  Non-U.S.
Shareholder  will not be required under the Foreign  Investment in Real Property
Tax Act to withhold on the purchase  price if the  purchased  common  shares are
"regularly  traded" on an established  securities  market or if our company is a
domestically-controlled  REIT.  Otherwise,  under the Foreign Investment in Real
Property Tax Act the  purchaser of our common shares may be required to withhold
10% of the purchase price and remit such amount to the Internal Revenue Service.

         Income   Taxation  of  the  Operating   Partnership,   our   Subsidiary
Partnerships and Their Partners.  The following  discussion  summarizes  certain
federal income tax considerations  applicable to our investment in the operating
partnership  and  the  indirect  interest  of  our  company  in  our  subsidiary
partnerships.

         Classification   of  the  Operating   Partnership  and  Our  Subsidiary
Partnerships.  We will be  entitled  to include  in our income our  distributive
share of the income and to deduct  our  distributive  share of the losses of the
operating partnership (including the operating partnership's share of the income
or losses of our subsidiary partnerships) only

909738.9
                                       24

<PAGE>



if the operating partnership (or our subsidiary  partnerships) is classified for
federal  income tax purposes as  partnerships  or, in the case of certain of our
subsidiary partnerships that are single-member limited liability companies,  are
disregarded as an entity separate from such member,  rather than as associations
taxable as corporations.  With certain  exceptions,  an unincorporated  domestic
organization  formed on or after  January  1, 1997 that has two or more  members
will be treated as a  partnership  for  federal  income tax  purposes  absent an
election  by such  organization  to be  treated as an  association  taxable as a
corporation. Such an organization formed prior to January 1, 1997 was treated as
a partnership  for federal income tax purposes  rather than as a corporation for
periods  prior to  January  1,  1997 only if it had no more than two of the four
corporate  characteristics  that the  Treasury  Regulations  applicable  to such
organizations  used to  distinguish  a partnership  from a  corporation  for tax
purposes. These four characteristics were continuity of life,  centralization of
management,  limited liability,  and free  transferability of interests.  Unless
such  organization   elects  otherwise,   the  classification   claimed  by  the
organization  prior to January  1, 1997 will  continue  for  periods on or after
January 1, 1997, and such classification will be respected for all prior periods
if  the  organization  had a  reasonable  basis  for  such  classification,  the
organization  and all  members of the  organization  recognized  the federal tax
consequences of any change in the  organization's  classification  within the 60
months prior to January 1, 1997, and neither the organization nor any member was
notified  in  writing on or before  May 8, 1996 that the  classification  of the
organization was under examination.

         We expect  that the  operating  partnership  and all of our  subsidiary
partnerships  formed on and after  January 1, 1997  either will have two or more
members at all times or, in the case of certain of our subsidiary  partnerships,
will have a single member, and that none of those organizations will elect to be
treated as an  association  for federal  income tax purposes.  In addition,  our
subsidiary  partnerships  in  existence  prior to  January  1,  1997 and  owned,
directly  or  indirectly,  by the  company  and its  predecessor  claimed  to be
partnerships  for all periods  prior to January 1, 1997 and were not notified in
writing on or before May 8, 1996 that such classification was under examination.
In the  opinion  of our tax  counsel,  which is based on the  provisions  of the
partnership  agreement  of the  operating  partnership  and on  certain  factual
assumptions and  representations,  the operating  partnership and our subsidiary
partnerships have been,  continue to be and will be, treated as partnerships for
federal  income tax  purposes or, in the case of those  subsidiary  partnerships
that are single-member  limited liability  companies,  will be disregarded as an
entity separate from such member. However, neither the operating partnership nor
any of our  subsidiary  partnerships  have  requested,  nor do  they  intend  to
request, a ruling from the Internal Revenue Service that they will be treated as
partnerships or disregarded, as applicable, for federal income tax purposes. Our
tax  counsel's  opinion is not binding on the  Internal  Revenue  Service or the
courts.

         A  publicly-traded  partnership  is a partnership  whose  interests are
traded  on an  established  securities  market  or are  readily  tradeable  on a
secondary  market (or the  substantial  equivalent  thereof).  A publicly traded
partnership  will be treated as a  corporation  for federal  income tax purposes
unless at least 90% of such  partnership's  gross  income for each  taxable year
consists of  "qualifying  income," which  generally  includes any income that is
qualifying income for purposes of the 95% gross income test applicable to REITs.
It is unclear whether the right of unit holders in the operating  partnership to
exchange  their  units  for  shares  of the  company  would  be  treated  as the
"substantial equivalent" of the units being readily tradeable.  However, because
it is anticipated that the operating partnership will meet the Qualifying Income
Exception,  it should not be treated as a corporation under the  publicly-traded
partnership  rules.  In  addition,  Treasury  Regulations  provide  certain safe
harbors that, if applicable,  will cause partnership  interests to be treated as
interests  that  are  not  readily  tradeable  on  a  secondary  market  or  the
substantial  equivalent thereof. If for any reason the operating  partnership or
one of our  subsidiary  partnerships  were taxable as a corporation  for federal
income tax purposes,  our company would not be able to satisfy the  requirements
for REIT status.

         Partners,  Not  Partnerships,  Subject to Tax. A  partnership  is not a
taxable entity for federal income tax purposes. Rather, a partner is required to
take into account its allocable share of a partnership's  income, gains, losses,
deductions, and credits for any taxable year of the partnership ending within or
with the taxable year of the partner,  without regard to whether the partner has
received or will receive any distributions from the partnership.

         Partnership   Allocations.   Although  a  partnership   agreement  will
generally  determine the  allocation of income and losses among  partners,  such
allocations  will be  disregarded  for tax purposes  under section 704(b) of the
Internal  Revenue  Code of 1986 if they do not  comply  with the  provisions  of
section 704(b) of the Internal Revenue Code of 1986 and the Treasury Regulations
promulgated thereunder as to substantial economic effect.

         If an allocation is not recognized for federal income tax purposes, the
item  subject to the  allocation  will be  reallocated  in  accordance  with the
partners' interests in the partnership,  which will be determined by taking into
account all of the facts and circumstances  relating to the economic arrangement
of the partners with respect to such item. The allocations of taxable income and
loss of the operating  partnership and our subsidiary  partnerships are intended
to comply with the  requirements of section 704(b) of the Internal  Revenue Code
of 1986 and the Treasury Regulations promulgated thereunder.

         Sale  of  Partnership  Property.  Generally,  any  gain  realized  by a
partnership  on the sale of property held by the  partnership  for more than one
year and allocated to a partner will be long-term  capital gain,  except for any
portion of such gain that is treated as depreciation or cost recovery recapture.
However,  under the REIT  requirements  imposed by the Internal  Revenue Code of
1986, our share, as a partner, of any gain realized by the operating partnership
or our subsidiary  partnerships on the sale of any property held as inventory or
other property held primarily for sale to customers in the ordinary  course of a
trade or business will be treated as income from a prohibited  transaction  that
is subject to a 100% penalty tax. See "--Taxation of Our Company" (p.18).

         Information Reporting  Requirements and Backup Withholding Tax. We will
report to our U.S.  Shareholders  and the Internal Revenue Service the amount of
distributions paid during each calendar year and the amount of tax withheld,  if
any. Under certain  circumstances,  U.S.  Shareholders  may be subject to backup
withholding  at a  rate  of 31%  with  respect  to  distributions  paid.  Backup
withholding will apply only if the shareholder (i) fails to furnish its taxpayer
identification  number  (which,  for an individual,  would be such  individual's
Social Security  number),  (ii) furnishes an incorrect  taxpayer  identification
number,  (iii) is notified by the  Internal  Revenue  Service that it has failed
properly to report  payments of interest and  dividends,  or (iv) under  certain
circumstances, fails to certify, under penalty of perjury, that it has furnished
a  correct  taxpayer  identification  number  and has not been  notified  by the
Internal Revenue Service that it is subject to backup withholding for failure to
report interest and dividend  payments.  Backup  withholding will not apply with
respect to payments made to certain exempt recipients,  such as corporations and
tax-exempt  organizations.  U.S.  Shareholders  should  consult  their  own  tax
advisors regarding their qualification for exemption from backup withholding and
the procedure for obtaining  such an  exemption.  Backup  withholding  is not an
additional tax. Rather,  the amount of any backup  withholding with respect to a
payment to a U.S.  Shareholder  will be allowed  as a credit  against  such U.S.
Shareholder's  United States  federal  income tax liability and may entitle such
U.S.  Shareholder  to a  refund,  provided  that  the  required  information  is
furnished to the Internal Revenue Service.

         Additional  issues may arise  pertaining to  information  reporting and
backup withholding with respect to Non- U.S. Shareholders. Non-U.S. Shareholders
should consult their tax advisors with respect to any such information reporting
and backup withholding requirements.

         State and Local Tax  Considerations.  We are, and our  shareholders may
be, subject to state or local taxation in various state or local  jurisdictions,
including  those  in  which  the  company,   its  shareholders,   the  operating
partnership  or our subsidiary  partnerships  transact  business or reside.  The
state and local tax  treatment of the company,  the operating  partnership,  our
subsidiary  partnerships  and our  shareholders  may not  conform to the federal
income tax consequences discussed above. Consequently,  prospective shareholders
should  consult  their own tax advisors  regarding the effect of state and local
tax laws on their investment in the company.

         Possible  Federal Tax  Developments.  The rules  dealing  with  federal
income taxation are constantly under review by the Internal Revenue Service, the
Treasury  Department,  Congress and the courts.  New federal tax  legislation or
other  provisions  may be enacted  into law or new  interpretations,  rulings or
Treasury  Regulations could be adopted or judicial  decisions  rendered,  all of
which  could  affect  the  taxation  of the  company  and its  shareholders.  No
prediction  can  be  made  as to the  likelihood  of  passage  of  any  new  tax
legislation or other provisions either directly

or indirectly affecting the company and its stockholders.  Consequently, the tax
treatment  described  herein may be modified  prospectively  or retroactively by
such legislative, judicial or administrative action.


                              SELLING SHAREHOLDERS

         As described elsewhere in this prospectus, the Selling Shareholders are
persons who either have  received our  restricted  common  shares or may receive
common shares in exchange for their OP Units. The following table sets forth, as
of March 2,  2000 the name of each  Selling  Shareholder,  the  number of common
shares  beneficially  owned by each  Selling  Shareholder,  and the  number  and
percentage  of our  common  shares  to be  beneficially  owned  by each  Selling
Shareholder  following  the  offering to which this  prospectus  relates.  Since
Selling  Shareholders  may sell all, some or none of their shares that are to be
offered by this  prospectus,  no estimate can be made of the aggregate number of
common shares  offered by this  prospectus,  or the  aggregate  number of common
shares that will be owned by each Selling  Shareholder  upon  completion  of the
offering to which this prospectus relates. Except as otherwise noted below, none
of the Selling  Shareholders has, within the past three years, had any position,
office or other material relationship with Acadia.

         The common shares  offered by this  prospectus may be offered from time
to time directly by the Selling Shareholders named below or by pledgees, donees,
transferees or other successors in interest thereto:

                              PLAN OF DISTRIBUTION

         This prospectus  relates to the offer and sale from time to time by the
persons listed under the Selling  Shareholders  section of this prospectus of up
to 26,719,319 common shares. We have issued 16,061,238  restricted common shares
to  certain  Selling  Shareholders  and may issue  further  shares to the extent
certain other Selling Shareholders exchange their 10,658,081 OP Units, including
294,934 OP Units  issuable upon the  conversion  of preferred OP Units,  held by
them in our subsidiary, the operating partnership, for an equal number of common
shares. We have registered the Selling Shareholders' common shares for resale to
provide them with freely tradeable  securities.  However,  registration of their
shares  does not  necessarily  mean that  they  will  offer or sell any of their
shares.  We will not receive  any  proceeds  from the  offering or sale of their
shares.

         Selling  Shareholders  (or  pledgees,   donees,  transferees  or  other
successors  in  interest)  may sell the common  shares to which this  prospectus
relates  from time to time on the New York  Stock  Exchange,  where  our  common
shares are listed for  trading,  in other  markets  where our common  shares are
traded, in negotiated transactions, through underwriters or dealers, directly to
one or more  purchasers,  through  agents or in a combination of such methods of
sale.  They will sell the common  shares at prices  which are  current  when the
sales take place or at other prices to which they agree. All costs, expenses and
fees in connection  with the  registration  of the common shares  offered hereby
will be borne by us. Brokerage commissions and similar selling expenses, if any,
attributable  to the sale of common shares  offered  hereby will be borne by the
Selling Shareholders.

         The Selling  Shareholders  may effect such  transactions by selling the
common shares offered hereby  directly to purchasers or through  broker-dealers,
which  may  act  as  agents  or  principals.  Such  broker-dealers  may  receive
compensation  in the form of discounts,  concessions,  or  commissions  from the
Selling  Shareholders  and/or the purchasers of the common shares offered hereby
for  whom  such  broker-dealers  may  act as  agents  or to  whom  they  sell as
principal, or both (which compensation as to a particular broker-dealer might be
in excess of customary commissions).

         In connection with an underwritten offering, underwriters or agents may
receive compensation in the form of discounts, concessions or commissions from a
Selling  Shareholder  or from  purchasers of the shares which are the subject of
this prospectus for whom they may act as agents,  and  underwriters may sell the
shares which are the subject of this prospectus to or through dealers,  and such
dealers  may  receive  compensation  in the form of  discounts,  concessions  or
commissions  from the  underwriters  and/or  commissions from the purchasers for
whom  they  may  act as  agents.  We  have  agreed  to  indemnify  each  Selling
Shareholder against certain liabilities, including liabilities arising under the
Securities  Act.  The Selling  Shareholders  may agree to  indemnify  any agent,
dealer or broker-dealer that participates in transactions involving sales of the
common shares offered hereby against certain liabilities,  including liabilities
arising under the Securities Act.

         The  shares  which  are  the  subject  of this  prospectus  may be sold
directly or through  broker-dealers acting as principal or agent, or pursuant to
a distribution by one or more  underwriters on a firm commitment or best-efforts
basis.  The methods by which the shares which are the subject of this prospectus
may be sold  include:  (a) a block trade in which the  broker-dealer  so engaged
will  attempt to sell such shares as agent but may position and resell a portion
of the block as principal to  facilitate  the  transaction;  (b)  purchases by a
broker-dealer  as principal  and resale by such  broker-  dealer for its account
pursuant  to  this   prospectus;   (c)  ordinary   brokerage   transactions  and
transactions  in  which  the  broker  solicits   purchasers;   (d)  an  exchange
distribution in accordance  with the rules of the New York Stock  Exchange;  (e)
privately  negotiated  transactions;  and  (f)  underwritten  transactions.  The
Selling  Shareholders and any underwriters,  dealers or agents  participating in
the  distribution  of the shares which are the subject of this prospectus may be
deemed to be  "underwriters"  within the meaning of the Securities  Act, and any
profit  on  the  sale  of  such  shares  by the  Selling  Shareholders  and  any
commissions received by any such broker-dealers may be deemed to be underwriting
commissions  under the  Securities  Act.  None of the Selling  Shareholders  has
informed us as to their plan of distribution.

Item 15.  Indemnification of Directors and Officers.

         Our bylaws and  declaration  of trust  authorize  our  company,  to the
extent  permitted  under Maryland law, to indemnify its trustees and officers in
their capacity as such.  Section  8-301(15) of the Maryland General  Corporation
Law  ("MGCL")  permits a  Maryland  REIT to  indemnify  or advance  expenses  to
trustees  and  officers to the same extent as is  permitted  for  directors  and
officers of a Maryland  corporation  under the MGCL The MGCL requires a Maryland
corporation  (unless its charter  provides  otherwise,  which our declaration of
trust does not) to indemnify a director or officer who has been  successful,  on
the merits or otherwise,  in the defense of any proceeding to which he is made a
party by reason of his  service in that  capacity.  The MGCL  permits a Maryland
corporation  to indemnify its present and former  directors and officers,  among
others, against judgments, penalties, fines, settlements and reasonable expenses
actually incurred by them in connection with any proceeding to which they may be
made a party by reason of their service in those or other  capacities  unless it
is  established  that (a) the act or  omission  of the  director  or officer was
material to the matter  giving rise to the  proceeding  and (i) was committed in
bad faith or (ii) was the result of active and  deliberate  dishonesty,  (b) the
director or officer  actually  received an improper  personal  benefit in money,
property or services or (c) in the case of any criminal proceeding, the director
or  officer  had  reasonable  cause  to  believe  that the act or  omission  was
unlawful.  However,  a Maryland  corporation  may not  indemnify  for an adverse
judgment  in a suit by or in the right of the  corporation  or for a judgment of
liability on the basis that a personal benefit was improperly  received,  unless
in either case a court orders  indemnification  and then only for  expenses.  In
addition,  the MGCL permits a corporation  to advance  reasonable  expenses to a
director or officer upon the corporation's  receipt of a written  affirmation by
the  director or officer of his or her good faith  belief that he or she has met
the standard of conduct necessary for  indemnification  by the corporation and a
written  undertaking  by such  director or officer on his or her behalf to repay
the amount paid or  reimbursed  by the  corporation  if it shall  ultimately  be
determined that the standard of conduct was not met.

         Our bylaws  also  permit the  company,  subject to the  approval of our
board of trustees, to indemnify and advance expenses to any person who served as
a predecessor of the company in any of the capacities described above and to any
employee or agent of the company or a predecessor of the company.

         In addition  to the above,  our company  has  purchased  and  maintains
insurance  on behalf  of all of its  trustees  and  executive  officers  against
liability asserted against or incurred by them in their official capacities with
the  company,  whether  or not the  company  is  required  or has the  power  to
indemnify them against the same liability.

      The undersigned registrant hereby undertakes:

                  (1)      To file, during any period in which offers or sales
are being made, a post-effective amendment to this registration statement;

                           (i)      To  include  any   prospectus   required  by
Section 10(a)(3) of the Securities Act of 1933;

                           (ii)     To  reflect in the  prospectus  any facts or
events  arising after the effective date of the  registration  statement (or the
most recent  post-effective  amendment  thereof)  which,  individually or in the
aggregate,  represent a fundamental  change in the  information set forth in the
registration statement.  Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was  registered)  and any deviation  from the low or
high and of the estimated maximum offering range may be reflected in the form of
a prospectus pursuant to Rule 424(b) if, in the aggregate, the changes in volume
and price represent no more than a 20% change in the maximum aggregate  offering
price set forth in the "Calculation of Registration  Fee" table in the effective
registration statement; and

                           (iii)    To include  any  material  information  with
respect to the plan of distribution not previously disclosed in the registration
statement  or any  material  change  to  such  information  in the  registration
statement;

                  Provided,  however,  that paragraphs (1)(i) and (1)(ii) do not
apply if the  registration  statement is on Form S-3,  Form S-8 or Form F-3, and
the information  required to be included in a post-effective  amendment by those
paragraphs  is  contained  in periodic  reports  filed with or  furnished to the
Commission by the  registrant  pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 that are  incorporated  by  reference  in the  registration
statement.

                  (2) That, for the purpose of determining  any liability  under
the Securities Act of 1933, each such  post-effective  amendment shall be deemed
to be a new registration  statement relating to the securities offering therein,
and the  offering  of such  securities  at that  time  shall be deemed to be the
initial bona fide offering thereof.

                  (3) To remove from registration by means of a post-effective
amendment any of the securities being registered which remain unsold at the
termination of the offering.

         The  undersigned  registrant  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
registrant's  annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 (and, where applicable,  each filing of an employee benefit
plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in the  registration  statement shall be
deemed to be a new  registration  statement  relating to the securities  offered
therein,  and the offering of such securities at that time shall be deemed to be
the  initial  bona  fide  offering  thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the  registrant  pursuant  to the  provisions  referred  to in  Item  15 of this
Registration  Statement,  or otherwise,  the registrant has been advised that in
the  opinion  of the SEC  such  indemnification  is  against  public  policy  as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for  indemnification  against  such  liabilities  (other than the payment by the
registrant of expenses incurred or paid by a director,  officer,  or controlling
person of the  registrant  in the  successful  defense of any action,  suit,  or
proceeding) is asserted by such

<PAGE>



director, officer, or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction  the question as to whether such  indemnification  by it is against
public  policy  as  expressed  in the act,  and will be  governed  by the  final
adjudication of such issue.

      re:      Acadia Realty Trust Registration of Common Shares of Beneficial
               Interest on Form S-3

Ladies and Gentlemen:

         We have acted as special counsel for Acadia Realty Trust, a Maryland
real estate investment trust (the "Trust"), in connection with the preparation
and filing of a registration statement on Form S-3 (the "Registration
Statement") under the Securities Act of 1933, as amended, pursuant to which the
Trust intends to register an aggregate of 26,719,319 shares of its Common Shares
of Beneficial Interest, par value $.001 per share ("Common Shares"), for resale
by the "Selling Shareholders" listed in the Registration Statement and the
prospectus included therein. This opinion is being furnished to you as a
supporting document for such Registration Statement.

         In this connection we have examined and considered the original or
copies, certified or otherwise identified to our satisfaction, of the following:

                   (i) The Declaration of Trust of the Trust including all
amendments thereto, as in effect on the date hereof,

                   (ii) The By-Laws of the Trust, including all amendments
thereto, as in effect on the date hereof,

                   (iii) The Resolutions of the Board of Trustees of the Trust,
adopted at meetings of the Board of Trustees on April 14, 1998 and May 28, 1998,
which among other things: (a) authorize the issuance of such number of Common
Shares and limited partnership interests in Acadia Realty Limited Partnership
("OP Units") as is necessary to effectuate the transactions contemplated by the
Contribution and Share Purchase Agreement dated April 15, 1998 (the "RDC
Transaction") and (b) reserve for issuance such number of Common Shares as is
necessary to effectuate the RDC Transaction,

Acadia Realty Trust                     2                        March 1, 2000



                   (iv) The Resolutions of the Board of Trustees of the Trust,
adopted pursuant to Unanimous Written Consent of the Trustees on February 17,
2000, which, among other things: (a) authorize the issuance of such number of
Common Shares and OP Units as is necessary to effectuate the transactions
contemplated by the Agreement of Contribution dated November 8, 1999 (the
"Pacesetter Transaction"), (b) reserve for issuance such number of Common Shares
and OP Units as is necessary to effectuate the Pacesetter Transaction, and (c)
authorize the filing of the Registration Statement,

                   (v) The Registration Statement filed with the Securities and
Exchange Commission, and

                   (vi) The Certificate of the Secretary of the Trust dated
March 1, 2000.

         In addition, we have obtained from public officials, officers and other
representatives of the Trust, and others such certificates, documents and
assurances as we considered necessary or appropriate for purposes of rendering
this opinion. In our examination of the documents listed in (i)-(vi) above and
the other certificates and documents referred to herein, we have assumed the
legal capacity of all natural persons, the genuineness of all signatures on
documents not executed in our presence and facsimile or photostatic copies of
which we reviewed, the authenticity of all documents submitted to us as
originals, the conformity to the original documents of all documents submitted
to us as certified or photostatic copies and the authenticity of the originals
of such documents. Without limiting the generality of the foregoing we have
relied upon the representations of the Trust as to the accuracy and completeness
of (i) the Declaration of Trust and the By-laws of the Trust; (ii) the
Registration Statement; and (iii) the representations of the Trust that (a) the
resolutions of the Trustees, dated April 14, 1998 and May 28, 1998, (b) the
resolutions of the Trustees dated February 17, 2000, (c) the Declaration of
Trust, and (d) the By- laws of the Trust have not been rescinded, modified or
revoked and no proceedings for the amendment, modification, or rescission of any
of such documents are pending or contemplated.

         Based upon the assumptions, qualifications, and limitations set forth
herein, and relying upon the statements of fact contained in the documents that
we have examined, we are of the opinion, as of the date hereof, that when the
Registration Statement becomes effective and any conditions for the issuance of
Common Shares have been complied with (including, for example, conversion of OP
Units in accordance with the Amended and Restated Agreement of Limited
Partnership of Acadia Realty Limited Partnership and conversion of OP Units
converted from preferred OP Units), the Common Shares shall constitute legally
issued, fully paid and nonassessable, and valid and binding obligations of the
Trust.

         In addition to the assumptions set forth above, the opinions set forth
herein are also subject to the following qualifications and limitations:

written consent. This opinion letter is rendered as of the date hereof, and we

Registration Statement and to the reference to our firm under the caption "Legal

                  Re:    Tax opinion

Gentlemen:

                  We have acted as counsel to Acadia Realty Trust, a Maryland
real estate investment trust (the "Company"), in connection with the
registration of up to 26,719,319 common shares of beneficial interest of the
Company (the "Shares"), $0.001 par value. The Shares may be offered for sale by
selling stockholders (the "Offering") pursuant to a registration statement (the
"Registration Statement") to be filed by the Company with the Securities and
Exchange Commission on Form S-3. All of the net proceeds of the Offering will be
retained by the selling stockholders and none of the net proceeds of the
Offering will be contributed to the Company or to Acadia Realty Limited
Partnership, a Delaware limited partnership (the "Operating Partnership"). You
have requested our opinion as to certain federal income tax matters in
connection with the Offering.

                  The Operating Partnership owns equity interests in existing
shopping centers (and certain other real property) and associated personal
property (the "Properties"). The Operating Partnership owns some of the
Properties directly and owns the remaining Properties through limited liability
companies or subsidiary partnerships (collectively, the "Subsidiary
Partnerships").

                  In connection with the opinions rendered below, we have
examined the following:

filed with the Secretary of State of Maryland;

                  2. the Company's Amended Bylaws;

                  3. the Registration Statement, including the prospectus
contained as part of the Registration Statement (the "Prospectus");

                  4. the Amended and Restated Agreement of Limited Partnership
of the Operating Partnership dated as of March 22, 1999 (the "Operating
Partnership Agreement"), among the Company, as general partner and several other

authorized, executed, and delivered; is authentic, if an original, or is
accurate, if a copy; and has not been amended;

                  2. during each taxable year, including its short taxable year
ending December 31, 1993, the Company has operated and will operate in such a
manner that will make the representations contained in the Representation
Letter, dated March 1, 2000 and executed by the President of the Company (the
"Representation Letter"), true for such years;

                  3. the Company will not make any amendments to its

                  4. neither the Operating Partnership or any Subsidiary
Partnership will make an election to be taxed as an association taxable as a
corporation or other than as a partnership pursuant to Treasury Regulation
ss.301.7701-3(c).

                  In connection with the opinions rendered below, we also have
relied upon the correctness of the representations contained in the
Representation Letter.

                  For purposes of our opinions, we made such factual and legal
inquiries, including examination of the documents set forth above, as we have
deemed necessary or appropriate for purposes of our opinion. For purposes of
rendering our opinion, however, we have not made an independent investigation of
the facts contained in the documents and assumptions set forth above, the
representations set forth in the Representation Letter, or the Prospectus. We
consequently have relied upon the representations in the Representation Letter
that the information presented in such documents or otherwise furnished to us is
accurate and complete in all material respects relevant to our opinion.

                  We have acted as counsel to the Company since August 12, 1998.
Accordingly, the first full taxable year for which we have acted as counsel to
the Company is the taxable year ending December 31, 1999, and our opinion
rendered below does not address any period before January 1, 1999. We have
assumed that, for periods prior to January 1, 1999, the Company qualified to be
taxed as a REIT pursuant to sections 856 through 860 of the Code and that the
Operating Partnership and the Subsidiary Partnerships were properly treated for
federal income tax purposes as partnerships and not as associations taxable as
corporations or as publicly traded partnerships.

                  In addition, to the extent that any of the representations
provided to us in the Representation Letter are with respect to matters set
forth in the Internal Revenue Code of 1986, as amended (the "Code"), or the
Treasury regulations thereunder (the "Regulations"), we have reviewed with the
individual making such representation the relevant portion of the Code and the
applicable Regulations and are reasonably satisfied that such individual
understands such provisions and is capable of making such representations.

                  Based on the documents and assumptions set forth above, the
representations set forth in the Representation Letter, and the discussion in
the Prospectus under the caption "Federal Income Tax Considerations" (which is
incorporated herein by reference), we are of the opinion that:

Acadia Realty Trust                                               March 1, 2000




                  (a) commencing with the Company's taxable year ending December
         31, 1999, the Company qualified and will qualify to be taxed as a REIT
         pursuant to sections 856 through 860 of the Code, and the Company's
         proposed method of operation will enable it to continue to meet the
         requirements for qualification and taxation as a REIT under the Code;

                  (b) the descriptions of the law and the legal conclusions
         contained in the Prospectus under the caption "Federal Income Tax
         Considerations" are correct in all material respects, and the
         discussion contained therein fairly summarizes the federal tax
         considerations that are material to a holder of the Common Shares; and

                  (c) the Operating Partnership and the Subsidiary Partnerships
         will be treated for federal income tax purposes as partnerships and not
         as associations taxable as corporations or as publicly traded
         partnerships.

We assume no obligation to advise you of any changes in our opinion subsequent
to the delivery of this opinion letter. The Company's qualification and taxation
as a REIT depends upon the Company's ability to meet on a continuing basis,
through actual annual operating and other results, the various requirements
under the Code with regard to, among other things, the sources of its gross
income, the composition of its assets, the level of its distributions to
stockholders, and the diversity of its stock ownership. We will not review on a
continuing basis the Company's compliance with the documents or assumptions set
forth above, or the representations set forth in the Representation Letter.
Accordingly, no assurance can be given that the actual results of the Company's
operations the sources of its income, the nature of its assets, the level of the
Company's distributions to its stockholders and the diversity of the Company's
stock ownership for any given taxable year will satisfy the requirements for
qualification and taxation as a REIT.

                  The foregoing opinions are based on current provisions of the
Code and the Regulations, published administrative interpretations thereof, and
published court decisions. The Internal Revenue Service has not issued
Regulations or administrative interpretations with respect to various provisions
of the Code relating to REIT qualification. No assurance can be given that the
law will not change in a way that will prevent the Company from qualifying as a
REIT, or the Operating Partnership or the Subsidiary Partnerships from being
classified as partnerships for federal income tax purposes.

                  We hereby consent to the filing of this opinion as an exhibit
to the Registration Statement. We also consent to the references to Battle
Fowler LLP under the captions "Federal Income Tax Considerations" and "Legal
Matters" in the Prospectus.

      determining Capital Accounts as a result of a distribution other than in
      complete liquidation of a Partner's Partnership Interest, the amount of

      basis of the asset) from the disposition of the asset and shall be taken

Partner's sole discretion, and the Contributing Partner or (b) the quotient
(rounded to the nearest whole number) arrived at by dividing (x) the Gross Asset
Value of the property contributed as additional Capital Contributions (net of
any debt to which such property is subject or assumed by the Partnership in
connection with such contribution) by (y) the Market Price (as hereinafter
defined). The number of OP Units issued to the General Partner under clause (ii)
of this Section 3.2(B) shall be equal to the number of Common Shares issued. As
used in this Section 3.2(B), "Market Price" means the average, for the most
recent twenty (20) trading days for the Common Shares preceding the date on
which such OP Units are to be issued pursuant to this Section 3.2(B), of the
last reported sale price per Common Share at the close of trading on each such
date as reported by the Wall Street Journal (New York Edition) or such other
reputable stock price reporting service as may be selected by the General
Partner.

          Any additional Partnership Interests which may be issued may be OP
Units or other Partnership Interests in one or more classes, or one or more
series of such classes, with such designations, preferences and relative,
participating, optional or other special rights, powers and duties, including
rights, powers and duties which may be senior, pari passu or junior to OP Units,
all as shall be determined by the General Partner in its sole and absolute
discretion subject to Delaware law, including, without limitation (i) the
allocations of items of Partnership income, gain, loss, deduction and credit to
each such class or series of Partnership Interests; (ii) the right of each such
class or series of Partnership Interests to share in Partnership distributions;
and (iii) the rights of each such class or series of Partnership Interests upon
dissolution and liquidation of the Partnership; provided that no such additional
Partnership Interests shall be issued to the General Partner unless either
(A)(1) the additional Partnership Interests are issued in connection with the
issuance of shares of Securities by the General Partner, which Securities have
designations, preferences and other rights such that the economic interests
attributed to such Securities are substantially similar to the designations,
preferences and other rights of the additional Partnership Interests issued to
the General Partner in accordance with this Section 3.2(B), and (2) subject to
any exceptions set forth in this Section 3.2(B), the General Partner shall make
a Capital Contribution to the Partnership in an amount equal to the proceeds
raised in connection with the issuance of such shares of the General Partner, or
(B) the additional Partnership Interests are issued to all the Partners in
proportion to their respective Percentage Interests.

          C.    Percentage Interest Adjustments. In the event that the
Partnership issues additional Partnership Interests (including additional
classes of Partnership Interests, (but excluding OP Units issued upon the
redemption of Preferred Units), the General Partner shall allocate to such
additional Partnership Interests a Percentage Interest in the Partnership equal
to a fraction, the numerator of which is equal to either (a) such amount as may
be fixed by agreement between the General Partner, in the General Partner's
sole discretion, and the Contributing Partner or (b) the amount of cash, if
any, plus the Gross Asset Value of the

796300.10
                                       -8-

<PAGE>



property, if any, contributed as additional Capital Contributions (net of any
debt to which such property is subject or assumed by the Partnership in
connection with such contribution) with respect to such additional Partnership
Interests and the denominator of which is equal to the fair market value (as
determined by the General Partner as of the date of such contribution taking
into account such contribution) of all the Partnership Interests for all
outstanding classes of Partnership Interests (including such additional
Partnership Interests). To the extent that any such issuance of additional
Partnership Interests results in an overall decrease (the "Percentage Decrease")
in the aggregate Percentage Interests in the Partnership represented by all of
the Partnership Interests that were outstanding before the issuance of the
additional Partnership Interests, the Percentage Decrease shall be allocated
among the classes of Partnership Interests outstanding prior to the issuance of
the additional Partnership Interests in accordance with such classes' respective
Percentage Interests in the Partnership as determined prior to the issuance of
the additional Partnership Interests. Similarly, to the extent that a redemption
by the General Partner of any Partnership Interests for cash results in an
overall increase (the "Percentage Increase") in the aggregate Percentage
Interests in the Partnership represented by the remaining Partnership Interests
outstanding after the redemption (the "Remaining Interests"), the Percentage
Increase shall be allocated among the classes of Remaining Interests by
multiplying the Percentage Increase by a fraction equal to the aggregate
pre-redemption Percentage Interests of all Remaining Interests of the particular
class divided by the aggregate pre-redemption Percentage Interests of all
Remaining Interests of all classes. Upon the redemption of any Preferred Units
for OP Units, the aggregate Percentage Interest allocated to that class of
Preferred Units shall be reduced by the total Percentage Interests attributable
to the redeemed Preferred Units (the "Preferred Redemption Percentage"), and the
aggregate Percentage Interest allocated to the OP Units shall be increased by
that Preferred Redemption Percentage.

          D.    From time to time, the General Partner shall cause the
Partnership to issue additional general Partnership Interests to the General
Partner in connection with the issuance by the General Partner of additional
Common Shares in exchange for OP Units as provided in Section 3.8 hereof. The
amount of general Partnership Interests issued under this Section 3.3(D) shall
be equal to the amount of OP Units exchanged for Common Shares (subject to the
anti-dilution protections set forth in Section 3.8).

          E.    If the Common Shares (or any other class of Securities of the
General Partner for which a class of Partnership Interests may be redeemed)
undergoes any split or reverse split, then without further action or consent by
the General Partner or any Limited Partner, each corresponding class of
Partnership Interests that is redeemable for Securities shall be split or
combined in accordance with the same ratio used to split or combine the
Securities. For example, if the Common Shares undergo a reverse 2 for 1 split
(i.e. every two shares of old Common Shares are converted into one share of new
Common Shares) then the corresponding class of Partnership Interests that are
redeemable for such Common Shares shall undergo a similar reverse split (i.e.
every two old OP Units shall be converted into one new OP Unit). Similarly, if
any class of Partnership Interests into which another class of

796300.10
                                       -9-

<PAGE>



Partnership Interests is convertible undergoes any split or reverse split, then
without further action or consent by the General Partner or any Limited Partner
the latter class of Partnership Interests shall be split or combined in
accordance with the same ratio used to split or combine the first class of
Partnership Interests.

          3.3 Additional Capital.

          A.    No Partner shall be assessed or, except as provided for in
Section 3.3(B) below, required to contribute additional funds or other property
to the Partnership. Any additional funds or other property required by
the Partnership, as determined by the General Partner in its sole discretion,
may, at the option of the General Partner and without an obligation to do so
(except as provided for in Section 3.3(B) below), be contributed by the
General Partner as additional Capital Contributions. If and as the General
Partner or any other Partner makes additional Capital Contributions to the
Partnership, each such Partner shall receive additional Partnership Interests
as provided for in Section 3.2(B) above. The General Partner shall also have
the right (but not the obligation) to raise any additional funds required for
the Partnership by causing the Partnership to borrow the necessary funds from
third parties on such terms and conditions as the General Partner shall deem
appropriate in its sole discretion. If the General Partner elects to cause the
Partnership to borrow the additional funds, it may cause one or more of the
Partnership's assets to be encumbered to secure the loan. Except as provided
for in Section 3.3(C) below, no Limited Partner shall have the right to
contribute additional Capital Contributions to the Partnership without the
prior written consent of the General Partner.

          B.    (i) The net proceeds of any and all funds raised by or through
the General Partner through the issuance of additional Securities shall be
contributed to the Partnership as additional Capital Contributions, and in such
event the General Partner shall be issued additional Partnership Interests
pursuant to Section 3.2(B) above.

              (ii) If the Partnership requires funds at any time or from time to
time in excess of funds available to the Partnership through borrowings and
prior or additional Capital Contributions, the General Partner may, but shall
not be required to, borrow such funds from a financial institution or other
lender or through public debt offerings and lend such funds to the Partnership
on the same terms and conditions as are applicable to the General Partner.

          C.    So long as a dividend reinvestment plan is in effect for the
holders of the Common Shares, each Limited Partner shall have the right to
reinvest any or all cash distributions payable to it from time to time pursuant
to this Agreement by having some or all (as the Limited Partner elects) of such
distributions contributed to the Partnership as additional Capital
Contributions, and in such event the Partnership shall issue to each such
Limited Partner additional OP Units pursuant to Section 3.2(B) above. The
General Partner shall create and administer a reinvestment program to effect the
foregoing in substantial

796300.10
                                      -10-

<PAGE>



conformance with any dividend reinvestment program available from time to time
to holders of the Common Stock.

          3.4    Capital Accounts. A separate capital account("Capital Account")
shall be maintained for each Partner.

          A.    To each Partner's Capital Account there shall be credited such
Partner's Capital Contributions, such Partner's distributive share of Profits
and any items in the nature of income or gain which are specifically allocated
pursuant to Section 7.3 or Section 7.4 hereof, and the amount of any Partnership
liabilities assumed by such Partner or which are secured by any Partnership
property distributed to such Partner.

          B.    To each Partner's Capital Account there shall be debited the
amount of cash and the Gross Asset Value of any Partnership property distributed
to such Partner pursuant to any provision of this Agreement, such Partner's
distributive share of Losses and any items in the nature of expenses or losses
which are specifically allocated pursuant to Section 7.3 or Section 7.4 hereof,
and the amount of any liabilities of such Partner assumed by the Partnership or
which are secured by any property contributed by such Partner to the
Partnership.

          C.    In the event all or a portion of a Partnership Interest is
transferred in accordance with the terms of this Agreement (including a transfer
of OP Units in exchange for Common Shares of the General Partner, pursuant to
Section 3.8), the transferee shall succeed to the Capital Account of the
transferor to the extent it relates to the transferred Partnership Interest.

          D.    In determining the amount of any liability for purposes of
Sections 3.4(A) and 3.4 (B) hereof, there shall be taken into account Code
Section 752(c) and any other applicable provisions of the Code and Regulations.

          E.    This Section 3.4 and the other provisions of this Agreement
relating to the maintenance of Capital Accounts are intended to comply with
Regulations Section 1.704-1(b), and shall be interpreted and applied in a manner
consistent with such Regulations. In the event the General Partner shall
determine that it is prudent to modify the manner in which the Capital Accounts,
or any debits or credits thereto (including, without limitation, debits or
credits relating to liabilities which are secured by contributed or distributed
property or which are assumed by the Partnership, or the Partners) are computed
in order to comply with such Regulations, the General Partner may make such
modification, provided that it is not likely to have a material effect on the
amounts distributed to any Partner pursuant to Section 14 hereof upon the
dissolution of the Partnership or would otherwise not have a material adverse
effect on any Partner or any Partner's Capital Account. The General Partner also
shall (i) make any adjustments that are necessary or appropriate to maintain
equality between the Capital Accounts of the Partners and the amount of
Partnership capital reflected on the

796300.10
                                      -11-

<PAGE>



Partnership's balance sheet, as computed for book purposes, in accordance with
Regulations Section 1.704-1(b) (2) (iv) (g), and (ii) make any appropriate
modifications in the event unanticipated events might otherwise cause this
Agreement not to comply with Regulations Section 1.704-1(b), provided, that such
adjustments or modifications, to the extent they may be made in the discretion
of the General Partner, shall not, either singly or in the aggregate, have a
material adverse effect on any Partner or any Partner's Capital Account.

          3.5    Interest on and Return of Capital.

          A.    No Partner shall be entitled to any interest on its Capital
Account or on its contributions to the capital of the Partnership.

          B.    Except as expressly provided for in this Agreement, not Partner
shall have the right to demand or to receive the return of all or any part of
his capital contributions to the Partnership and there shall be no priority of
one Partner over the other as to the return of capital contributions or
withdrawals or distributions of profits and losses. No Partner shall have the
right to demand or receive property other than cash in return for the
contributions of such Partner to the Partnership.

          3.6    Negative Capital Accounts. No Partner shall be required to pay
to the Partnership any deficit or negative balance which may exist in its
Capital Account.

          3.7    Limit on Contributions and Obligations of Partners. Neither the
Limited Partners nor the General Partner shall be required to make any
additional advance or contributions to or on behalf of the Partnership or to
endorse any obligations of the Partnership.

          3.8    Conversion of OP Units. Subject to the further provisions of
this Section 3.8, the General Partner hereby grants to each Limited Partner the
right to exchange any or all of the OP Units held by that Partner for Common
Shares, with one OP Unit being exchangeable for one Common Share. Such right
may be exercised by a Limited Partner at any time and from time to time upon
not less than ten (10) days prior written notice to the General Partner or at
such times as may be otherwise agreed to by the Limited Partner, on the one
hand, and the Partnership or the General Partner, on the other hand. The
General Partner shall at all times reserve and keep available out of its
authorized but unissued Common Shares, solely for the purpose of effecting the
exchange of OP Units for Common Shares, such number of Common Shares as shall
from time to time be sufficient to effect the conversion of all outstanding OP
Units not owned by the General Partner. No Limited Partner shall, by virtue of
being the holder of one or more OP Units, be deemed to be a shareholder of or
have any other interest in the General Partner. The exchange of OP Units for
Common Shares described in this Section 3.8 may be effected by the contribution
of Common Shares from the General Partner to the Partnership and the redemption
by the Partnership of OP Units held by a Limited Partner. In the event of any
change in the outstanding Common Shares by reason of any share

796300.10
                                      -12-

<PAGE>



dividend, split, recapitalization, merger, consolidation, combination, exchange
of shares or other similar corporate change, the number of OP Units held by each
Partner shall be proportionately adjusted so that one OP Unit remains
exchangeable for one Common Share without dilution. In the event the General
Partner issues any Common Shares in exchange for OP Units pursuant to this
Section 3.8, any such OP Units so acquired by the General Partner shall
immediately thereafter be canceled by the Partnership and the Partnership shall
issue to the General Partner new OP Units pursuant to Section 3.2(B)(ii) hereof.
Notwithstanding the foregoing provisions of this Section 3.8, a Limited Partner
shall not have the right to exchange OP Units for Common Shares if (i) in the
opinion of counsel for the General Partner, the General Partner would, as a
result thereof, no longer qualify (or it would be likely that the General
Partner no longer would qualify) as a Real Estate Investment Trust; (ii) such
exchange would, in the opinion of counsel for the General Partner, constitute or
be likely to constitute a violation of applicable securities laws; or (iii) such
exchange would result in a Limited Partner exceeding the ownership limitation
provisions in the Declaration of Trust of the General Partner, as such
provisions shall then be in effect. If the General Partner is unable to issue
Common Shares in accordance with this Section 3.8, it shall cause the
Partnership to redeem the requested OP Units for cash for an amount equal to the
Market Price (as defined in Section 3.2(B)) calculated as if one OP Unit equaled
one Common Share (subject to the anti-dilution protections set forth in this
Section 3.8).

          No fractional Common Shares shall be issued in return for OP Units. If
more than one OP Unit shall be requested to be redeemed at the same time by the
same Limited Partner, the number of full Common Shares that shall be issuable
upon the redemption thereof shall be computed on the basis of the aggregate
number of Common Shares represented by the OP Units so presented. If any
fraction of a Common Share would, except for the provisions of this Section 3.8,
be issuable on the redemption of any OP Units (or specified portion thereof),
the General Partner shall pay an amount in cash equal to the Market Price
(determined as of the trading day immediately preceding the date upon the
closing of the conversion of the OP Units is to occur), multiplied by such
fraction.

          4.    Principal Office. The principal office of the Partnership shall
be located at the principal office of the General Partner, or at such other
place as the General Partner may designate after giving written notice of such
designation to the other Partners.

          5. Purpose and Powers of the Partnership.
             -------------------------------------

          A.    The purposes of the Partnership shall be to acquire, purchase,
own, operate, manage, develop, redevelop, construct, improve, invest in,
finance, refinance, sell, lease and otherwise deal with real property and
assets related thereto, and interests therein (including, without limitation,
debt), whether directly or indirectly, alone or in association with others.
The purposes of the Partnership include, but are not limited to:


796300.10
                                      -13-

<PAGE>



          (i)    acquiring, developing, operating, leasing and managing real
      property and conducting any other lawful business relating thereto;

          (ii)    mortgaging, exchanging, selling, encumbering or otherwise
      disposing of all or any part of a real property or any interest therein;

          (iii)    constructing, reconstructing, altering, modifying and
      subtracting from or adding to a real property or any part thereof;

          (iv)    organizing and holding partnership interests in partnerships
      owning or otherwise having an interest in, whether directly or indirectly,
      one or more real properties; and

          (v)    in general, the making of any investments or expenditures, the
      borrowing and lending of money and the taking of any and all actions which
      are incidental or related to any of the purposes recited above.

          It is agreed that each of the foregoing is an ordinary part of the
Partnership's business and affairs. Property may be acquired subject to, or by
assuming, the liens, encumbrances, and other title exceptions which affect such
property. The Partnership may also be a partner, general or limited, in
partnerships, general or limited, and joint ventures created to accomplish all
or any of the foregoing.

          B.    The Partnership purposes may be accomplished by taking any
action which is not prohibited under the Act and which is related to the
acquisition, ownership, development, improvement, operation, management,
financing, leasing, exchanging, selling or otherwise encumbering or disposing
of all or any portion of the assets of the Partnership, or any interest therein.

          C.    Notwithstanding anything to the contrary contained in this
Agreement, for so long as Acadia Realty Trust is a Partner, the Partnership
shall operate in such a manner and the Partnership shall take or omit to take
all actions as may be necessary (including making appropriate distributions from
time to time), so as to permit Acadia Realty Trust (i) to continue to qualify as
a Real Estate Investment Trust under Sections 856 through 860 of the Code so
long as such requirements exist and as such provisions may be amended from time
to time, or corresponding provisions of succeeding law (the "REIT
Requirements"), and (ii) to minimize its exposure to the imposition of an excise
tax under Section 4981(a) of the Code or a tax under Section 857(b) (5) of the
Code, so long as such taxes may be imposed and as such provisions may be amended
from time to time, or corresponding provisions of succeeding law, each of (i)
and (ii) to at all times be determined (a) as if Acadia Realty Trust's sole
asset is its Partnership Interest, and (b) without regard to the action or
inaction of Acadia Realty Trust with respect to distributions (by way of
dividends or otherwise) and the timing thereof. In addition, the Partnership
shall take no action with respect to a sale, exchange or other disposition of
any

796300.10
                                      -14-

<PAGE>



property owned by the Partnership with respect to which a material issue exists
as to whether such sale, exchange or other disposition would cause Acadia Realty
Trust to incur a prohibited transaction tax under Section 857(b) (6) of the
Code.

          D.    Without the consent of all of the Limited Partners affected
thereby, the General Partner may not change its policy of holding its assets and
conducting its business solely through the Partnership or structure any
transactions described in Section 5(E) or 5(F) in a manner which will change the
General Partner's policy of holding its assets and conducting its business
through the Partnership (or the Surviving Partnership (defined below), if
applicable)), if the result of such transaction is the recognition of gain for
federal income tax purposes by such Limited Partners.

          E.    Whether or not Section 5(D) hereof is applicable, the General
Partner shall not, unless Section 5(F) is applicable, engage in any merger,
consolidation or other combination with or into another person, sale of all or
substantially all of its assets or any reclassification, recapitalization or
similar transaction (each a "Termination Transaction"), unless such Termination
Transaction is one in connection with which each Limited Partner either will
receive, or will have the right to elect to receive, for each OP Unit held by
such Limited Partner, an amount of cash, securities, or other property equal to
the product of the number of Common Shares into which such OP Unit is
convertible (or in the case of a Series A Preferred Unit, the number of OP Units
into which such Series A Preferred Unit is convertible) and the greatest amount
of cash, securities or other property paid to a holder of one Common Share in
consideration of one Common Share pursuant to the terms of the Termination
Transaction; provided that; if, in connection with the Termination Transaction,
a purchase, tender or exchange offer shall have been made to and accepted by the
holders of the outstanding Common Shares, each holder of OP Units (but not
Series A Preferred Units or any other class of Partnership Interests that is not
directly redeemable for Common Shares) shall receive, or shall have the right to
elect to receive, the greatest amount of cash, securities, or other property
which such holder would have received had it exercised its exchange right (as
set forth in Section 3.8) and received Common Shares in exchange for its OP
Units immediately prior to the expiration of such purchase, tender or exchange
offer and had thereupon accepted such purchase, tender or exchange offer and
then such Termination Transaction shall have been consummated.

          F.    Whether or not Section 5(D) hereof is applicable, the General
Partner may merge, or otherwise combine its assets, with another entity without
satisfying the requirements of Section 5(E) hereof if: (i) immediately after
such merger or other combination, substantially all of the assets directly or
indirectly owned by the surviving entity, other than OP Units held by such
General Partner, are owned directly or indirectly by the Partnership or another
limited partnership or limited liability company which is the survivor of a
merger, consolidation or combination of assets with the Partnership (in each
case, the "Surviving Partnership"); (ii) the Limited Partners own a percentage
interest of the Surviving Partnership based on the relative fair market value of
the net assets of the Partnership (as determined

796300.10
                                      -15-

<PAGE>



pursuant to Section 5(G)) and the relative fair market value of the other net
assets of the Surviving Partnership (as determined pursuant to Section 5(G))
immediately prior to the consummation of such transaction; (iii) the rights,
preferences and privileges of each class of Limited Partners in the Surviving
Partnership are at least as favorable as those in effect immediately prior to
the consummation of such transaction and as those applicable to any other
limited partners or non-managing members of the Surviving Partnership; and (iv)
such rights of the Limited Partners include the right to exchange their
interests in the Surviving Partnership for at least one of: (A) the
consideration available to such Limited Partners pursuant to Section 5(E), or
(B) if the ultimate controlling person of the Surviving Partnership has publicly
traded common equal securities, such common equity securities, with an exchange
ratio based on the relative fair market value of such securities (as determined
pursuant to Section 5(G)) and the Common Shares.

          G.    In connection with any transaction permitted by Section 5(E) or
5(F), the relative fair market values shall be reasonably determined by the
General Partner in good faith as of the time of such transaction and, to the
extent applicable, shall be no less favorable to the Limited Partners than the
relative values reflected in the terms of such transactions.

          6.    Term. The term of the Partnership shall continue until the
Partnership is terminated upon the occurrence of an event described in
Section 14.1 below.

          7. Allocations.
             -----------

          7.1    Profits. After giving effect to the special allocations set
forth in Sections 7.3 and 7.4 hereof, Profits for any fiscal year shall be
allocated among the Partners in proportion to their respective Percentage
Interests.

          7.2 Losses.

          A.    After giving effect to the special allocations set forth in
Sections 7.3 and 7.4 hereof, Losses for any fiscal year shall be allocated among
the Partners in proportion to their respective Percentage Interests.

          B.    The Losses allocated pursuant to Section 7.2(A) hereof shall not
exceed the maximum amount of Losses that can be so allocated without causing any
Limited Partner to have an Adjusted Capital Account Deficit at the end of any
fiscal year. All Losses in excess of the limitations set forth in this Section
7.2(B) shall be allocated to the General Partner.

          7.3    Special Allocations. Subject to Section 7.6 hereof, the
following special allocations shall be made in the following order:

          A.    Minimum Gain Chargeback. Except as otherwise provided in
Regulations Section 1.704-2(f), notwithstanding any other provision of this
Section 7, if there

796300.10
                                      -16-

<PAGE>



is a net decrease in Partnership Minimum Gain during any fiscal year, each
Partner shall be specially allocated items of Partnership income and gain for
such fiscal year (and, if necessary, subsequent fiscal years) in an amount equal
to such Partner's share of the net decrease in Partnership Minimum Gain,
determined in accordance with Regulations Section 1.704-2(g). The items to be so
allocated shall be determined in accordance with Regulations Section 1.704-
2(f)(6) and 1.704-2(j)(2). This Section 7.3(A) is intended to comply with
minimum gain chargeback requirements in Section 1.704-2(f) of the Regulations
and shall be interpreted consistently therewith.

          B.    Partner Minimum Gain Chargeback. Except as otherwise provided in
Regulations Section 1.704-2(i)(4), notwithstanding any other provision of this
Section 7, if there is a net decrease in Partner Nonrecourse Debt Minimum Gain
attributable to a Partner Nonrecourse Debt during any Partnership fiscal year,
each Partner who has a share of the Partner Nonrecourse Debt Minimum Gain
attributable to such Partner Nonrecourse Debt determined in accordance with
Regulations Section 1.704-2(i) (5) shall be specially allocated items of
Partnership income and gain for such fiscal year (and, if necessary, subsequent
fiscal years) in an amount equal to such Partner's share of the net decrease in
Partner Nonrecourse Debt Minimum Gain attributable to such Partner Nonrecourse
Debt, determined in accordance with Regulations Section 1.704-2 (i) (4). The
items to be so allocated shall be determined in accordance with Regulations
Sections 1.704-2(i) (4) and 1.704-2(i) (2). This Section 7.3(B) is intended to
comply with the minimum gain chargeback requirement in Regulations Section
1.704-2(i) (4) and shall be interpreted consistently therewith.

          C.    Qualified Income Offset. In the event any Partner unexpectedly
receives any adjustments, allocations, or distributions described in
Regulations Section 1.704-1(b) (2) (ii) (d) (4), Section 1.704-1(b)(2) (ii)
(d) (5), or Section 1.704-1(b) (2) (ii) (d) (6), items of Partnership income
and gain shall be specially allocated to each such Partner in an amount and
manner sufficient to eliminate, to the extent required by the Regulations, the
Adjusted Capital Account Deficit of such Partner as quickly as possible,
provided that an allocation pursuant to this Section 7.3(C) shall be made only
if and to the extent that such Partner would have an Adjusted Capital Account
Deficit after all other allocations provided for this Section 7 have been
tentatively made, as if this Section 7.3(C) were not in the Agreement.

          D. Gross Income Allocation. In the event any Partner has an Adjusted
Capital Account Deficit at the end of any Partnership fiscal year, each such
Partner shall be specifically allocated items of Partnership income and gain
in the amount of such excess as quickly as possible, provided that an
allocation pursuant to this Section 7.3 (D) shall be made only if and to the
extent that such Partner would have an Adjusted Capital Account Deficit after
all other allocations provided for in this Section 7 have been made as if
Section 7.3(C) hereof and this Section 7.3(D) were not in the Agreement.

          E.    Nonrecourse Deductions. Nonrecourse Deductions for any fiscal
year shall be allocated among the Partners in accordance with their respective
Percentage Interests.

                                      -17-

<PAGE>




          F.    Partner Nonrecourse Deductions. Any Partner Nonrecourse
Deductions for any fiscal year shall be specially allocated to the Partner
who bears the economic risk of loss with respect to the Partner Nonrecourse
Debt to which such Partner Nonrecourse Deductions are attributable, in
accordance with Regulations Section 1.704-2(i) (1).

          G.    Section 754 Adjustments. The Partnership shall make a timely
election under Section 754 such that the General Partner may adjust the tax
basis of the Partnership assets pursuant to Section 743(b), if appropriate, upon
an exchange of OP Units for Common Shares. In addition, to the extent an
adjustment to the adjusted tax basis of any Partnerships asset pursuant to Code
Sections 734(b) or 743(b) is required, pursuant to Regulations Section
1.704-1(b) (2) (iv) (m) to be taken into account in determining Capital Accounts
as a result of a distribution to a Partner in complete liquidation of his
interest in the Partnership, the amount of such adjustment to Capital Accounts
shall be treated as an item of gain (if the adjustment increases the basis of
the asset) or loss (if the adjustment decreases such basis) and such gain or
loss shall be specifically allocated to the Partner in accordance with such
Partner's Percentage Interest in the event that Regulations Section 1.704-1(b)
(2) (iv) (m) (2) applies, or the Partners to whom such distribution was made in
the event that Regulations Section 1.704-1(b) (2) (iv) (m) (4) applies.

          H.    Allocations with Respect to Partnership Interests other than OP
Units. In the event the Partnership issues additional classes of Preferred Units
or other classes of Partnership Interests other than OP Units, then the General
Partner shall determine, in its sole discretion, the Profits and Losses
attributable to each class (subject to the requirement that the Profits
attributed to any class must bear a reasonable relationship to the amount of
cash distributions to that class) and shall allocate the Profits and Losses of
each class of Partnership Interests among the Partners in such class in
proportion to their respective percentage interests in such class, after giving
effect to any and all special allocations set forth in Sections 7.3 and 7.4
above.

          7.4    Curative Allocations. The allocations set forth in Sections
7.2(B), 7.3(A), 7.3(B), 7.3(C), 7.3(D), 7.3(E), 7.3(F) and 7.3(G) hereof (the
"Regulatory Allocations") are intended to comply with certain requirements of
the Regulations under Sections 704(b) and 514(c) (9) (E) of the Code. It is the
intent of the Partners that, to the extent possible, all Regulatory Allocations
shall be offset either with other Regulatory Allocations or with special
allocations of other items of Partnership income, gain, loss, or deduction
pursuant to this Section 7.4. Therefore, notwithstanding any other provision of
this Section 7 (other than the Regulatory Allocations and Section 7.6), the
General Partner shall make such offsetting special allocations of Partnership
income, gain, loss, or deduction in whatever manner it determines appropriate so
that, after such offsetting allocations are made, each Partner's Capital Account
balance is, to the extent possible, equal to the Capital Account balance such
Partner would have had if the Regulatory Allocations were not part of the
Agreement and all Partnership items were allocated pursuant to Sections 7.1 and
7.2(A), and

796300.10
                                      -18-

<PAGE>



so that, to the greatest extent possible, such allocations comply with the
Regulations under Code Section 514(c) (9) (E). In exercising its discretion
under this Section 7.4, the General Partner shall take into account future
Regulatory Allocations under Section 7.3 (A) and 7.3(B) that, although not yet
made, are likely to offset other Regulatory Allocations previously made under
Sections 7.3(E) and 7.3(F).

          7.5 Other Allocation Rules.

          A.    For purposes of determining the Profits, Losses, or any other
items allocable to any period, Profits, Losses, and any such other items shall
be determined on a daily, monthly or other basis, as determined by the General
Partner using any permissible method under Code Section 706 and the Regulations
thereunder.

          B.    The Partners are aware of the income tax consequences of the
allocations made by this Section 7 and hereby agree to be bound by the
provisions of this Section 7 in reporting their shares of Partnership income and
loss for income tax purposes.

          C.    Solely for purposes of determining a Partner's proportionate
share of the "excess nonrecourse liabilities" of the Partnership within the
meaning of Regulations Section 1.752-3(a) (3), the Partners' interests in
Partnership Profits are equal to their respective Percentage Interests.

          7.6 Tax Allocations: Code Section 704(c).

          A.    Notwithstanding any other provision herein to the contrary,
income, gain, loss, and deduction with respect to any property contributed to
the capital of the Partnership shall, solely for tax purposes, be allocated
among the Partners so as to take account of any variation between the adjusted
basis of such property to the Partnership for federal income tax purposes and
its initial Gross Asset Value in accordance with Code Section 704(c) and
Regulations Section 1.704-3 using the "traditional method" unless otherwise
determined by the General Partner and the Contributing Partner.

          B.    In the event the Gross Asset Value of any Partnership asset is
adjusted pursuant to the definition of "Gross Asset Value" contained in Section
2 hereof, subsequent allocations of income gain, loss, and deduction with
respect to such asset shall take account of any variation between the adjusted
basis of such asset for federal income tax purposes and its Gross Asset Value in
the same manner as set forth in Section 7.6A above.

          C.    Allocations pursuant to this Section 7.6 are solely for purposes
of federal, state, and local taxes and shall not affect, or in any way be taken
into account in computing, any Partner's Capital Account or share of Profits,
Losses, other items, or distributions pursuant to any provision in this
Agreement.

          8. Cash Available for Distribution.
             -------------------------------

          8.1    Operating Cash Flow. As used in this Agreement, "Operating Cash
Flow" shall mean and be defined as all cash receipts of the Partnership from
whatever source (but excluding Capital Cash Flow and proceeds of Capital
Contributions) during the period in question in excess of all items of
Partnership expense (including prepaid expense, financing costs and similar
items but excluding non-cash expenses such as depreciation and costs and
expenses paid with Capital Contributions) and other cash needs of the
Partnership, including, without limitation, amounts paid by the Partnership as
principal on debts and advances, during such period, capital expenditures and
any reserves (as reasonably determined by the General Partner) established or
increased during such period provided that the expenses listed in Section 8.2
shall not be considered expenses under this Section 8.1. In the discretion of
the General Partner, reserves may include cash held for future acquisitions.
Operating Cash Flow shall be distributed to or for the benefit of the Partners
not less frequently than annually, and shall be distributed (i) first, to
holders of any class of Preferred Units in accordance with their Percentage
Interests in an amount equal to all preferential distributions on such Preferred
Units as set forth in the Unit Certificate for such class and at the times set
forth therein, and (ii) thereafter, to the extent of the remaining amount, to
and among the other Partners in accordance with their respective Percentage
Interests; or

          8.2    Capital Cash Flow. As used in this Agreement, "Capital Cash
Flow" shall mean and be defined as collectively (a) gross proceeds realized in
connection with the sale of any assets of the Partnership, (b) gross financing
or refinancing proceeds, (c) gross condemnation proceeds (excluding condemnation
proceeds applied to restoration of remaining property) and (d) gross insurance
proceeds (excluding rental insurance proceeds or insurance proceeds applied to
restoration of property), less (a) closing costs, (b) the cost to discharge any
Partnership financing encumbering or otherwise associated with the asset(s) in
question, (c) the establishment of reserves (as determined by the General
Partner, and which may include cash held for future acquisitions), and (d) other
expenses of the Partnership then due and owing. Subject to Section 14.2 below,
if applicable, Capital Cash Flow shall be distributed to or for the benefit of
the Partners not less frequently than annually and in any event as provided in
the Unit Certificate and shall be distributed first to the holders of Preferred
Units in the order of their preference and next to the other Partners, in
accordance with the respective Percentage Interests of the Partners on the date
of such distribution.

          8.3    Consent to Distributions. Each of the Partners hereby consents
to the distributions provided for in this Agreement. The General Partner shall
determine, in accordance with the terms of this Agreement and the Unit
Certificates, the amounts to be distributed to the Partners from time to time.


796300.10
                                      -20-

<PAGE>



          8.4    Distributions to General Partner's Shareholders. To the extent
available after providing for the preferences and the rights of the Partners,
Operating Cash Flow and Capital Cash Flow shall be distributed to the General
Partner in the amount necessary to satisfy the payment of distributions to the
General Partner's shareholders as such distributions are determined by the
General Partner.

          8.5    Additional Classes of Partnership Interests. Notwithstanding
the foregoing provisions of this Article 8, in the event the Partnership issues
additional classes of Partnership Interests other than OP Units, then the
General Partner shall determine, in its sole discretion (subject to Section
7.3(H)), the amount of distributions of Operating Cash Flow and Capital Cash
Flow attributable to each class in accordance with the Unit Certificates and
shall distribute such Operating Cash Flow and Capital Cash Flow to each class of
Partnership Interests among the Partners in such class in proportion to their
respective Percentage Interests in such class or otherwise as required pursuant
to the terms of such Partnership Interests.

          9. Management of Partnership.
             -------------------------

          9.1    General Partner. The General Partner shall be the sole manager
of the Partnership business, and shall have the right and power to make all
decisions and take any and every action with respect to the property, the
business and affairs of the Partnership and shall have all the rights, power and
authority generally conferred by law, or necessary, advisable or consistent with
accomplishing the purposes of the Partnership. All such decisions or actions
made or taken by the General Partner hereunder shall be binding upon all of the
Partners and the Partnership. The powers of the General Partner to manage the
Partnership business shall include, without limitation, the power and authority
to:

          (i)    operate any business normal or customary for the owner of or
      investor in real properties;

          (ii)    perform any and all acts necessary or appropriate to the
      operation of the Partnership assets, including, but not limited to,
      applications for rezoning, objections to rezoning of other property and
      the establishment of bank accounts in the name of the Partnership;

          (iii)    procure and maintain with responsible companies such
      insurance as may be available in such amounts and covering such risks as
      are deemed appropriate by the General Partner;

      Partnership;

796300.10
                                      -21-

<PAGE>




          (vi)    borrow money, finance and refinance the assets of the
      Partnership or any part thereof or interest therein and in connection
      with such borrowing, execute and deliver documents that evidence and
      secure the loans which permit the holders of the loans to confess
      judgment against the Partnership;

          (vii)    coordinate all accounting and clerical functions of the
      Partnership and employ such accountants, lawyers, property managers,
      leasing agents and other management or service personnel as may from time
      to time be required to carry on the business of the Partnership;

          (viii)    acquire, encumber, sell, ground lease or otherwise dispose
      of any or all of the assets of the Partnership, or any part thereof or
      interest therein; and

          (ix)    organize one or more partnerships or corporations which are
      controlled, directly or indirectly, by the Partnership and make any
      capital contributions required pursuant to the partnership agreements of
      any such partnerships.

          9.2    Limitations on Powers and Authorities of Partners.
Notwithstanding the powers of the General Partner set forth in Section 9.1
above, no Partner shall have the right or power to do any of the following:

          (i)    do any act in contravention of this Agreement, or any amendment
      hereto; or

          (ii)    do any act which would make it impossible to carry on the
      ordinary business of the Partnership, except to the extent that such act
      is specifically permitted by the terms hereof (it being understood and
      agreed that, except as hereafter provided in this Section 9.2, a sale of
      any or all of the assets of the Partnership, for example, would be an
      ordinary part of the Partnership's business and affairs and is
      specifically permitted hereby; or

          9.3    Limited Partners. The Limited Partners shall have no right or
authority to act for or to bind the Partnership and no Limited Partner shall
participate in the conduct or control of the Partnership's affairs or business;
provided, however, that the exercise of the Limited Partners' rights under this
Agreement shall not be considered to be participation in such conduct or
control.

          9.4    Liability of General Partner. The General Partner shall not be
liable or accountable, in damages or otherwise, to the Partnership or to any
other Partner for any error of judgment or for any mistakes of fact or law or
for anything which it may do or refrain from doing hereafter in connection with
the business and affairs of the Partnership except (i) in the

796300.10
                                      -22-

<PAGE>



case of fraud, willful misconduct (such as an intentional breach of fiduciary
duty or an intentional breach of this Agreement) or gross negligence, and (ii)
for other breaches of this Agreement, but the liability of the General Partner
under this clause (ii) shall be limited to its interest in the Partnership as
more particularly provided for in Section 9.8 below. The General Partner shall
not have any personal liability for the return of any Limited Partner's capital.

          9.5    Indemnity. The Partnership shall indemnify and shall hold the
General Partner (and the officers and directors thereof) harmless from any loss
or damage, including without limitation reasonable legal fees and court costs,
incurred by it by reason of anything it may do or refrain from doing hereafter
for and on behalf of the Partnership or in connection with its business or
affairs; provided, however, that (i) the Partnership shall not be required to
indemnify the General Partner (or any officer or director thereof) for any loss
or damage which it might incur as a result of its fraud, willful misconduct or
gross negligence in the performance of its duties hereunder and (ii) this
indemnification shall not relieve the General Partner of its proportionate part
of the obligations of the Partnership as a Partner. The right of indemnification
set forth in this Section 9.5 shall be in addition to any rights to which the
person or entity seeking indemnification may otherwise be entitled and shall
inure to the benefit of the successors and assigns or any such person or entity.
No Partner shall be personally liable with respect to any claim for
indemnification pursuant to this Section 9.5, but such claim shall be satisfied
solely out of assets of the Partnership. Notwithstanding the foregoing
provisions of this Section 9.5, the General Partner shall be entitled to
reimbursement by the Partnership for any amounts paid by it in satisfaction of
indemnification obligations owed by the General Partner to present or former
directors of the General Partner or its predecessors, as provided for in or
pursuant to the Articles of Incorporation and By-Laws of the General Partner.

          9.6    Other Activities of Partners and Agreements with Related
Parties. The General Partner shall devote its full-time efforts in furtherance
of the Partnership business and shall conduct all of its activities
exclusively through the Partnership and shall not conduct or engage in any
way in any other business; provided, however, that the General Partner may
enter into or conduct business through a wholly owned subsidiary or otherwise
if such business is in connection with, or incidental to, the management
of the business of the Partnership. Except as may otherwise be agreed to in
writing, each Limited Partner, and its affiliates, shall be free to engage in,
to conduct or to participate in any business or activity whatsoever, including,
without limitation, the acquisition, development, management and exploitation
of real and personal property (other than property of the Partnership), without
any accountability, liability or obligation whatsoever to the Partnership or to
any other Partner, even if such business or activity competes with or is
enhanced by the business of the Partnership. The General Partner, in the
exercise of its power and authority under this Agreement, may contract and
otherwise deal with or otherwise obligate the Partnership to entities in which
the General Partner or any one or more of the officers, directors or
shareholders of the General Partner may have an ownership or other financial
interest, whether direct or indirect; provided, however, that without the
approval of a majority of the disinterested trustees of the General

796300.10
                                      -23-

<PAGE>



Partner, the General Partner will not (i) acquire from or sell to any trustee,
officer or employee of the General Partner or the Partnership, or any person in
which a trustee, officer or employee of the General Partner or the Partnership
owns more than a 1% interest, or acquire from or sell to any affiliate of any of
the foregoing, any of the assets or other property of the General Partner, (ii)
make any loan to or borrow from any of the foregoing persons, (iii) engage in
any other transaction with any of the foregoing persons or (iv) dispose of any
of the initial 31 properties set forth on Schedule B hereto; provided further
that the foregoing shall not affect , or be deemed a waiver by the Limited
Partners of, the General Partner's fiduciary obligations to the Partnership.

          9.7 Other Matters Concerning the General Partner.

          A.    The General Partner shall be protected in relying, acting or
refraining from acting on any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, bond, debenture, or other
paper or document believed by it to be genuine and to have been signed or
presented by the proper party or parties.

          B.    The General Partner may exercise any of the powers granted or
perform any of the duties imposed by this Agreement either directly or through
agents. The General Partner may consult with counsel, accountants, appraisers,
management consultants, investment bankers and other consultants selected by it,
each of whom may serve as consultants for the Partnership. An opinion by any
consultant on a matter which the General Partner believes to be within its
professional or expert competence shall be full and complete protection as to
any action taken or omitted by the General Partner based on the opinion and
taken or omitted in good faith. The General Partner shall not be responsible for
the misconduct, negligence, acts or omissions of any consultant or contractor of
the Partnership or of the General Partner, and shall assume no obligations other
than to use due care in the selection of all consultants and contractors.

          C.    No mortgagee, grantee, creditor or any other person dealing with
the Partnership shall be required to investigate the authority of the General
Partner or secure the approval of or confirmation by any Limited Partner of any
act of the General Partner in connection with the conduct of the Partnership
business.

          D.    The General Partner may retain such persons or entities as it
shall determine (subject to Section 9.6, including the General Partner or any
entity in which the General Partner shall have an interest or with which it is
affiliated) to provide services to or on behalf of the Partnership. The General
Partner shall be entitled to reimbursement from the Partnership for its
out-of-pocket expenses (subject to Section 9.6, including, without limitation,
amounts paid or payable to the General Partner or any entity in which the
General Partner shall have an interest or with which it is affiliated) incurred
in connection with Partnership business. Such expenses shall be deemed to
include those expenses required in connection with the administration of the
Partnership such as the maintenance of Partnership books and records,

796300.10
                                      -24-

management of the Partnership property and assets and preparation of information
respecting the Partnership needed by the Partners in the preparation of their
individual tax returns.

          9.8 Partner Exculpation.

          A.    Except for fraud, willful misconduct and gross negligence, no
Partner shall have any personal liability whatever, whether to the Partnership
or to the other Partner, for the debts or liabilities of the Partnership or its
obligations hereunder, and the full recourse of the other Partner shall be
limited to the interest of that Partner in the Partnership. To the fullest
extent permitted by law, no officer, director or shareholder of the General
Partner shall be liable to the Partnership for money damages except for (i)
active and deliberate dishonesty established by a final judgment or (ii) actual
receipt of an improper benefit or profit in money, property or services. Without
limitation of the foregoing, and except for fraud, willful misconduct and gross
negligence, no property or assets of any Partner, other than its interest in the
Partnership, shall be subject to levy, execution or other enforcement procedures
for the satisfaction of any judgment (or other judicial process) in favor of any
other Partner(s) and arising out of, or in connection with, this Agreement. This
Agreement is executed by the officers of each Partner solely as officers of the
same and not in their own individual capacities. No advisor, trustee, director,
officer, partner, employee, beneficiary, shareholder, participant or agent of
any Partner (or of any Partner of a Partner) shall be personally liable in any
matter or to any extent under or in connection with this Agreement, and the
Partnership, each Partner and their respective successors and assigns shall look
solely to the interest of the other Partner in the Partnership for the payment
of any claim or for any performance hereunder.


          9.9    General Partner Expenses and Liabilities.

          A.    All costs and expenses incurred by the General Partner in
connection with its activities as the General Partner hereunder, all costs and
expenses incurred by the General Partner in connection with its continued
corporate existence, qualification as a Real Estate Investment Trust under the
Code and otherwise, and all other liabilities incurred or suffered by the
General Partner in connection with the pursuit of its business and affairs as
contemplated hereunder and in connection with its activities as the General
Partner hereunder, shall be paid (or reimbursed to the General Partner, if paid
by the General Partner) by the Partnership.

          B.    Notwithstanding any provisions to the contrary set forth in this
Agreement, the amount of any distributions, payments or reimbursements pursuant
to this Agreement to the General Partner shall be reduced by any amount derived
by the General Partner from any investments owned directly by the General
Partner (including without limitation amounts derived from its ownership of
those subsidiaries described in Section 9.6).


796300.10
                                      -25-

<PAGE>



          C.    Notwithstanding anything contained herein to the contrary, if
the proceeds actually received and thereafter contributed to the Partnership
by the General Partner pursuant to any additional issuance as described in
Section 3.2(B) are less than the gross proceeds of such issuance as a result
of any underwriter's discount or other expenses paid or incurred in connection
with such issuance, then the General Partner shall be deemed to have made a
Capital Contribution to the Partnership in the amount of the gross proceeds of
such issuance and the Partnership shall be deemed simultaneously to have
reimbursed the General Partner pursuant to this Section 9.9 for the amount of
such underwriter's discount or other expenses.

          10.    Banking. The funds of the Partnership shall be kept in accounts
designated by the General Partner and all withdrawals therefrom shall be made on
such signature or signatures as shall be designated by the General Partner.

          11. Accounting.
              ----------

          11.1    Fiscal Year. The fiscal year of the Partnership shall end on
the last day of December of each year, unless another fiscal year end is
selected by the General Partner.

          11.2    Books of Account. The Partnership books of account shall be
maintained at the principal office designated in Section 4 above or at such
other locations and by such person or persons as may be designated by the
General Partner. The Partnership shall pay the expense of maintaining its books
of account. Each Partner shall have, during reasonable business hours and upon
reasonable prior notice, access to the books of the Partnership and in addition,
at its expense, shall have the right to copy such books. The General Partner, at
the expense of the Partnership, shall cause to be prepared and distributed to
the Partners annual financial data sufficient to reflect the status and
operations of the Partnership and its assets and to enable each Partner to file
its federal income tax return.

          11.3    Method of Accounting. The Partnership books of account shall
be maintained and kept, and its income, gains, losses and deductions shall be
accounted for, in accordance with sound principles of accounting consistently
applied, or such other method of accounting as may be adopted hereafter by the
General Partner. All elections and options available to the Partnership for
Federal or state income tax purposes shall be taken or rejected by the
Partnership in the sole discretion of the General Partner.

          11.4    Section 754 Election. In case of a distribution of property
made in the manner provided in Section 734 of the Code (or any similar provision
enacted in lieu thereof), or in the case of a transfer of any interest in the
Partnership permitted by this Agreement made in the manner provided in Section
743 of the Code (or any similar provision enacted in lieu thereof), the General
Partner, on behalf of the Partnership, may, in its sole discretion, file an
election under Section 754 of the Code (or any similar provision enacted in lieu
thereof) in accordance with the procedures set forth in the applicable
Regulations.

          11.5    Tax Matters Partner. The General Partner is hereby designated
the Tax Matters Partner (hereinafter referred to as the "TMP") of the
Partnership and shall have all the rights and obligations of the TMP under the
Code.

          11.6    Administrative Adjustments. If the TMP receives notice of a
Final Partnership Administrative Adjustment (the "FPAA") or if a request for an
administrative adjustment made by the TMP is not allowed by the United States
Internal Revenue Service (the "IRS") and the IRS does not notify the TMP of the
beginning of an administrative proceeding with respect to the Partnership's
taxable year to which such request relates (or if the IRS so notifies the TMP
but fails to mail a timely notice of an FPAA), the TMP may, but shall not be
obligated to, petition a Court for readjustment of partnership items. In the
case of notice of an FPAA, if the TMP determines that the United States District
Court or Claims Court is the most appropriate forum for such a petition, the TMP
shall notify each person who was a Partner at any time during the Partnership's
taxable year to which the IRS notice relates of the approximate amount by which
its tax liability would be increased (based on such assumptions as the TMP may
in good faith make) if the treatment of partnership items on his return was made
consistent with the treatment of partnership items on the Partnership's return,
as adjusted by the FPAA. Unless each such person deposits with the TMP, for
deposit with the IRS, the approximate amount of his increased tax liability,
together with a written agreement to make additional deposits if required to
satisfy the jurisdictional requirements of the Court, within thirty days after
the TMP's notice to such person, the TMP shall not file a petition in such

          12. Transfers of Partnership Interests.
              ----------------------------------

          A.    General Partner. In no event may the General Partner at any time
assign, sell, transfer, pledge, hypothecate or otherwise dispose of all or any
portion of its Partnership Interest, except by operation of law and in a manner
consistent with the rights of other Partners.

          B. Limited Partner.
             ---------------

          (i) No Limited Partner or substituted Limited Partner shall, without
      the prior written consent of the General Partner (which consent may be
      given or withheld in the sole discretion of the General Partner), sell,
      assign, distribute or otherwise transfer (a "Transfer") all or any part of
      his interest in the Partnership except by operation of law, gift (outright
      or in trust) or by sale, in each case to or for the benefit of a Permitted
      Transferee (as defined below), except for (a) pledges or other collateral
      transfers effected by a Limited Partner to secure the repayment of a loan
      and (b) the exchange of OP Units for Common Shares, pursuant to Section
      3.8 above. For purposes of this Section 12(B)(i), the term "Permitted
      Transferee" means (i) any partner or other equity owner of a Limited
      Partner; (ii)

796300.10
                                      -27-

<PAGE>



an equity owner of any partner or other equity owner of a Limited Partner; (iii)
members of the Immediate Family (as defined below) of any equity owner of a
Limited Partner (or any equity owner thereof) and trusts for the benefit of one
or more members of the Immediate Family of the Limited Partner (or any equity
owner thereof) created for a state and/or gift tax purposes and/or (iv) any
public charity, public foundation or charitable institution as defined in
Section 501(C)(3) of the Code or (v) any entity entirely owned and controlled by
the Limited Partner or by any of the persons or entities described in clauses
(i) through (iv). For purposes of this Section 12(B)(i), the term "Immediate
Family" means, with respect to any natural person, such natural person's spouse,
parents, parents-in-law, descendants, nephews, nieces, brothers, sisters,
brothers-in-law, sisters-in-law and children-in-law. A Limited Partner shall
notify the General Partner of any Transfer of beneficial interest or other
interest which occurs without a transfer of record ownership, as well as any
pledge or other collateral transfer. No part of the interest of a Limited
Partner shall be subject to the claims of any creditor, any spouse for alimony
support, or to legal process, and may not be voluntarily or involuntarily
alienated or encumbered except as may be specifically provided for in this
Agreement. A Limited Partner shall not be permitted to retire or withdraw from
the Partnership except as expressly permitted by this Agreement.

          (ii) An assignee, legatee, distributee or other transferee (whether by
      conveyance, will or the laws of intestacy, operation of law or otherwise)
      (a "Transferee") of all or any portion of a Limited Partner's interest in
      the Partnership shall be entitled to receive Profits, Losses and
      distributions hereunder attributable to such interest acquired by reason
      of such Transfer, from and after the effective date of the Transfer of
      such interest; provided, however, anything in this Agreement to the
      contrary notwithstanding, (a) no Transferee shall be considered a
      substituted Limited Partner until such Transfer has been consented to by
      the General Partner and (b) the Partnership and the General Partner shall
      be entitled to treat the transferor of such interest as the absolute owner
      thereof in all respects, and shall incur no liability for the allocation
      of Profits and Losses or distributions which are made to such transferor
      until such time as the written instrument of Transfer has been received by
      the General Partner and the "effective date" of the Transfer has passed.
      The "effective date" of any Transfer shall be the last day of the month
      set forth on the written instrument of Transfer or such other date
      consented to in writing by the General Partner as the "effective date."

          C.    Admission Adjustments. The General Partner shall, when
necessary, cause this Agreement to be amended from time to time to reflect the
addition or withdrawal of Partners, including the corresponding adjustments to
Percentage Interests in accordance with Section 3.2(C).

          13.    Death, Legal Incompetency, Etc. of a Limited Partner. The
death, legal incompetency, insolvency, dissolution or bankruptcy of a Limited
Partner shall not dissolve or terminate the Partnership. Upon the death or
incapacity of an individual Limited Partner, such individual Limited Partner's
interest in the Partnership shall be transferred either by will, the

laws of intestacy or otherwise to the legal representative or successor of such
individual Limited Partner.

          14.    Termination, Liquidation and Dissolution of Partnership.
                 -------------------------------------------------------

          14.1    Termination Events. The Partnership shall be dissolved and its
affairs wound up in the manner hereinafter provided upon the earliest to occur
of the following events:

          (i)    December 31, 2080; or

          (ii)    the agreement of those Partners holding at least ninety-five
      percent (95%) of the Percentage Interests of all of the Partners entitled
      to vote, determining that the Partnership should be dissolved;

          (iii) the General Partner shall hold in excess of ninety-five percent
      (95%) of the Percentage Interests of all of the Partners; or

          (iv)    the entry of a final judgment, order or decree of a court of
      competent jurisdiction adjudicating as bankrupt either the Partnership or
      the General Partner, and the expiration without appeal of the period, if
      any, allowed by applicable law to appeal therefrom.

          14.2 Method of Liquidation. Upon the happening of any of the events
specified in Section 14.1 above, the General Partner (or if there be no General
Partner, a liquidating trustee selected by those Limited Partners holding in the
aggregate more than fifty percent (50%) of the Percentage Interests held by all
Limited Partners entitled to vote) shall immediately commence to wind up the
Partnership's affairs and shall liquidate the assets of the Partnership as
promptly as possible, unless the General Partner, or the liquidating trustee,
shall determine that an immediate sale of Partnership assets would cause undue
loss to the Partnership, in which event the liquidation may be deferred to a
reasonable time. The Partners shall continue to share Operating Cash Flow,
Capital Cash Flow, Profits and Losses during the period of liquidation in the
same proportions as before dissolution. The proceeds from liquidation of the
Partnership, including repayment of any debts of Partners to the Partnership,
shall be applied in the order of priority as follows:

          A.    Debts of the Partnership, including repayment of principal and
interest on loans and advances made by the General Partner pursuant to Section
3.3 above; then

          B.    To the establishment of any reserves deemed necessary or
appropriate by the General Partner, or by the person(s) winding up the affairs
of the Partnership in the event there is no remaining General Partner of the
Partnership, for any contingent or unforeseen liabilities or obligations of the
Partnership. Such reserves established hereunder shall be held

796300.10
                                      -29-

<PAGE>



for the purpose of repaying any such contingent or unforeseen liabilities or
obligations and, at the expiration of such period as the General Partner, or
such person(s) deems advisable, the balance of such reserves shall be
distributed in the manner provided hereinafter in this Section 14.2 as though
such reserves had been distributed contemporaneously with the other funds
distributed hereunder; then

          C.    Then, to the Partners in accordance with their respective
Capital Account balances, after giving effect to all contributions,
distributions and allocations for all periods.

          14.3    Date of Termination. The Partnership shall be terminated when
all notes received in connection with such disposition have been paid and all
of the cash or property available for application and distribution under
Section 14.2 above (including reserves) shall have been applied and distributed
in accordance therewith.

          15.    Power of Attorney. Each Limited Partner hereby irrevocably
constitutes and appoints the President of the General Partner, with full power
of substitution, its true and lawful attorney, for him and in his name, place
and stead and for his use and benefit to do the following and for no other
purpose and provided the taking of any action authorized under this Section will
not result in any liability to the Limited Partners, to sign, swear to,
acknowledge, file and record:

          (i)    this Agreement, and subject to Section 16 below, amendments to
      this Agreement;

          (ii)    any certificates, instruments and documents (including assumed
      and fictitious name certificates) as may be required by, or may be
      appropriate under, the laws of the State of Delaware or any other State or
      jurisdiction in which the Partnership is doing or intends to do business,
      in order to discharge the purposes of the Partnership or otherwise in
      connection with the use of the name or names used by the Partnership;

          (iii)    any other instrument which may be required to be filed or
      recorded by the Partnership on behalf of the Partners under the laws of
      any State or by any governmental agency in order for the Partnership to
      conduct its business;

          (iv)    any documents which may be required to effect the continuation
      of the Partnership, the admission of a substitute or additional Partner,
      or the dissolution and termination of the Partnership, provided such
      continuation, admission or dissolution and termination is not in violation
      of any provision of this Agreement; and


796300.10
                                      -30-

<PAGE>



          (v)    any documents which may be required or desirable to have the
      General Partner appointed, and act as, the "Tax Matters Partner" as
      described in the Code.

          The foregoing grant of authority is a special power of attorney
coupled with an interest, is irrevocable and shall survive the death or
incapacity of any individual Limited Partner, and shall survive the delivery of
any assignment by a Limited Partner of the whole or any portion of his interest
in the Partnership.

          16. Amendment of Agreement.
              ----------------------

          A.    (i) Amendments to this Agreement may only be proposed by the
General Partner.

                (ii) (a) The General Partner shall submit any proposed amendment
      to the Limited Partners.

                     (b) The General Partner shall seek the written vote of the
                Partners on the proposed amendment or shall call a meeting to
                vote thereon and to transact any other business that it may deem
                appropriate.

                     (c) For purposes of obtaining a written vote, the General
                Partner may require a response within a reasonable specified
                time, but not less than fifteen (15) days, and failure to
                respond in such time period shall constitute a vote which is
                consistent with the General Partner's recommendation with
                respect to the proposal.

                     (d) Except as provided in Section 16(B) or 16(C), a
                proposed amendment shall be adopted and be effective as an
                amendment hereto if it is approved by the General Partner and it
                receives the consent of Partners holding at least a majority of
                the Percentage Interests of the Partners (including Partnership
                Interests held by the General Partner).

          B.    (i) Notwithstanding anything to the contrary contained in
Section 16(A), the General Partner shall have the power, without the consent
of the Limited Partners, to amend this Agreement as may be required to
facilitate or implement any of the following purposes:

                     (a) to add to the obligations of the General Partner or
                surrender any right or power granted to the General Partner or
                any Affiliate of the General Partner for the benefit of the
                Limited Partners;

                     (b) to reflect the admission, substitution, termination, or
                withdrawal of Partners in accordance with this Agreement (which
                may be effected through the amendment or replacement of Annex
                A);

                     (c) to set forth the designations, rights, powers, duties,
                and preferences of the holders of any additional Partnership
                Interests issued pursuant to Section 3.2 hereof;

                     (d) to reflect a change that does not adversely affect the
                Limited Partners in any material respect, or to cure any
                ambiguity, correct or supplement any provision in this Agreement
                not inconsistent with law or with other provisions, or make
                other changes with respect to matters arising under this
                Agreement that will not be inconsistent with law or with the
                provisions of this Agreement; and

                     (e) to satisfy any requirements, conditions, or guidelines
                contained in any order, directive, opinion, ruling or regulation
                of a federal or state agency or contained in federal or state
                law.

                (ii) The General Partner shall promptly provide notice to the
      Limited Partners when any action under this Section 16(B) is taken.

          C.    Notwithstanding Sections 16(A) and 16(B) hereof, this Agreement
shall not be amended with respect to any Partner adversely affected without
the consent of such Partner(s) adversely affected if such amendment would

          17.3    Successors and Assigns. Any person acquiring or claiming an
interest in the Partnership, in any manner whatsoever, shall be subject to and
bound by all of the terms, conditions and obligations of this Agreement to which
his predecessor-in-interest was subject or bound, without regard to whether such
person has executed a counterpart hereof or any other document contemplated
hereby. No person, including the legal representative, heir or legatee of a
deceased Partner, shall have any rights or obligations greater than those set
forth in the Partnership or become a Partner thereof except as this Agreement,
and no person shall acquire an interest in expressly permitted by and pursuant
to the terms of this Agreement. Subject to the foregoing, and the provisions of
Section 12 above, this Agreement shall be binding upon and inure to the benefit
of the Partners and their respective successors, assigns, heirs, legal
representatives, executors and administrators.

          17.4    Duplicate Originals. For the convenience of the Partners, any
number of counterparts hereof may be executed, and each such counterpart shall
be deemed to be an original instrument, and all of which taken together shall
constitute one agreement.

herein have been inserted as a matter of convenience of reference only and
shall not control or affect the meaning or construction of any of the terms or
provisions herein.

the State of Delaware. Except to the extent the Act is inconsistent with the
provisions of this Agreement, the provisions of such Act shall apply to the

          17.7    Other Instruments. The parties hereto covenant and agree that
they will execute such other and further instruments and documents as, in the
opinion of the General Partner, are or may become necessary or desirable to

796300.10
                                      -33-

<PAGE>



          17.8    General Partner with Interest as Limited Partner. If the
General Partner ever has an interest as a Limited Partner in the Partnership,
the General Partner shall, with respect to such interest, enjoy all of the
rights and be subject to all of the obligations and duties of a Limited Partner.

          17.9    Legal Construction. In case any one or more of the provisions
contained in this Agreement shall for any reason be held to be invalid, illegal
or unenforceable in any respect, such invalidity, illegality or unenforceability
shall not affect any other provision hereof and this Agreement shall be
construed as if such invalid, illegal or unenforceable provision had never been
contained herein.

          17.10    Gender. Whenever the context shall so require, all words
herein in any gender shall be deemed to include the masculine, feminine or
neuter gender, all singular words shall include the plural, and all plural
words shall include the singular.

          17.11    Prior Agreements Superceded. This Agreement supercedes any
prior understandings or written or oral agreements amongst the Partners, or
any of them, respecting the within subject matter and contains the entire
understanding amongst the Partners with respect thereto.

          17.12    No Third Party Beneficiary. The terms and provisions of this
Agreement are for the exclusive use and benefit of the General Partner and the
Limited Partners and shall not inure to the benefit of any other person or
entity.

          17.13    Purchase for Investment. Each Partner represents, warrants
and agrees that it has acquired and continues to hold its interest in the
Partnership for its own account for investment only and not for the purpose of,
or with a view toward, the resale or distribution of all any part thereof, nor
with a view toward selling or otherwise distributing such interest or any part
thereof at any particular time or under any predetermined circumstances
provided, however, that in no event shall the exercise of a Partner's conversion
rights under this Agreement be deemed a violation of this covenant. Each Partner
further represents and warrants that it is a sophisticated investor, able and
accustomed to handling sophisticated financial matters for itself, particularly
real estate investments, and that it has a sufficiently high net worth that it
does not anticipate a need for the funds it has invested in the Partnership in
what it understands to be a highly speculative and illiquid investment.

          17.14    Waiver. No consent or waiver, express or implied, by any
Partner to or of any breach or default by any other Partner in the performance
by such other Partner of its obligations hereunder shall be deemed or construed
to be a consent to or waiver of any other breach or default in the performance
by such other Partner of the same or any other obligations of such Partner
hereunder. Failure on the part of any Partner to complain of any act or failure
to act on the part of any other Partner or to declare any other Partner in
default, irrespective of how long such failure continues, shall not constitute
a waiver by such Partner of its rights hereunder.

                    AMENDED & RESTATED PARTNERSHIP AGREEMENT
                    ----------------------------------------

                  THIS FIRST AMENDMENT, dated as of November 15, 1999, to the
Amended and Restated Partnership Agreement, dated as of March 22, 1999, (the
"Partnership Agreement"), of ACADIA REALTY LIMITED PARTNERSHIP, a Delaware

defined herein shall have the meanings given such terms in the Partnership
Agreement.

                                   BACKGROUND
                                   ----------

                  Since the date of the Partnership Agreement, certain Limited
Partners have (i) converted their OP Units to Common Shares of the General
Partner and (ii) transferred their OP Units to a new Limited Partner.

                  The General Partner, pursuant to the exercise of such
authority and in accordance with Section 12(C) of the Partnership Agreement, has
determined to execute this First Amendment to the Partnership Agreement to
evidence the changes to the ownership of OP Units due to the conversion and
transfer of such OP Units.

                  NOW, THEREFORE, the parties hereto, for good and sufficient
consideration and intending to be legally bound, hereby amend the Partnership
Agreement as follows:

                  1.    Annex "A" of the Partnership Agreement is hereby amended
and restated to reflect (i) changes to the ownership of OP Units due to the
conversion and transfer of certain OP Units and (ii) the admission of Cheerful
Corporation as a new Limited Partner as of ________, 1999 whose authorized
signature appears on the signature page hereto, which Limited Partner shall have
such number of OP Units as is set forth opposite such Limited Partner's name on
Annex "A". Annex "B" of the Partnership Agreement is hereby amended and restated
to reflect the Capital Contribution made by the new Limited Partner.

                  2.    By execution of this First Amendment to the Partnership
Agreement, the new Limited Partner agrees to be bound by each and every term of
the Partnership Agreement as amended hereby from and after the date hereof.

                  3.    This First Amendment may be executed in counterparts,
each of which shall constitute an original, but all together shall constitute
one and the same document.

                  4.    Except as expressly set forth in this First Amendment,
the Partnership Agreement is hereby ratified and confirmed in each and every
respect.

                    ----------------------------------------

         THIS SECOND AMENDMENT, dated as of November 18, 1999, to the Amended
and Restated Partnership Agreement, dated as of March 22, 1999, as amended by
the First Amendment dated as of November 15, 1999 (collectively, the
"Partnership Agreement"), of ACADIA REALTY LIMITED PARTNERSHIP, a Delaware
limited partnership (the "Partnership"). Capitalized terms used herein but not
defined herein shall have the meanings given such terms in the Partnership
Agreement.

                                   BACKGROUND
                                   ----------

         The Partnership is a party to a certain Agreement of Contribution dated
as of November 8, 1999 (the "Contribution Agreement") pursuant to which, among
other things, the Partnership has agreed to acquire partnership interests in
Pacesetter/Ramapo Associates, a New York limited partnership, in consideration
for, among other things, Preferred Units in the Partnership. Pursuant to Section
3.2(B) of the Partnership Agreement, the General Partner of the Partnership has
the power and authority to issue additional Partnership Interests to Persons in
exchange for additional Capital Contributions.

         The General Partner, pursuant to the exercise of such authority and in
accordance with Section 12(C) of the Partnership Agreement, has determined to
execute this Second Amendment to the Partnership Agreement to evidence the
issuance of additional Partnership Interests and the admission of the other
signatories hereto (the "Pacesetter Partners") as Limited Partners of the
Partnership.

         NOW, THEREFORE, the parties hereto, for good and sufficient
consideration and intending to be legally bound, hereby amend the Partnership
Agreement as follows:

         1.    Annex "A" of the Partnership Agreement is hereby amended and
restated to reflect the admission as Limited Partners on the date hereof of the
Pacesetter Partners whose authorized signatures appear on the signature page
hereto, each of whom shall have such number of Preferred Units as is set forth
opposite such signatory's name on Annex "A". Annex "B" of the Partnership
Agreement is hereby amended and restated to reflect the Capital Contributions
made by the Pacesetter Partners.

         2.    The Preferred Units issued hereby shall have the rights,
preferences, privileges and designations set forth in Annex "C" which is hereby
incorporated into the Partnership Agreement.

         3.    By execution of this Second Amendment to the Partnership
Agreement, each of the Pacesetter Partners agrees to be bound by each and every
term of the Partnership Agreement as amended hereby from and after the date
hereof.

         4.    This Second Amendment may be executed in counterparts, each of
which shall constitute an original, but all together shall constitute one and
the same document.

         5.    Except as expressly set forth in this Second Amendment, the
Partnership Agreement is hereby ratified and confirmed in each and every
respect.

                            [SIGNATURE PAGE FOLLOWS]

             (i) "Registrable Shares" means the Fund Shares and the Conversion
Shares and any other Shares issued in respect of such shares (because of share
splits, share dividends, reclassifications, recapitalizations, or similar
events); provided, however, that Shares which are Registrable Shares shall cease
to be Registrable Shares (x) upon any sale pursuant to a Registration Statement,
or any other sale or transfer of the Registrable Shares in any manner to any
person or entity other than as expressly provided herein, or (y) in the event
that Registrable Shares may be freely sold and/or transferred pursuant to Rule
144(k) under the Securities Act; provided, however, that notwithstanding the
provisions of clause (y), for purposes of such clause (y), the Fund Shares shall
be deemed to be Registrable Shares until 42 months after the Closing Date.

             (j) "Securities Act" means the Securities Act of 1933 or any

          2. Piggy-Back Registration.

             (a) If at any time and from time to time during the period
commencing upon the first anniversary of the Closing Date (the "Anniversary
Date") and ending upon the earlier of (i) such time as when all of the
Registrable Shares have been disposed of and (ii) three years after the
conversion into Shares of all OP Units issued under the Contribution Agreement,
the Company proposes to file a Registration Statement, it will, prior to such
filing, give written notice to the RDC Funds and to the Owners of its intention
to do so and, upon the written request of the RDC Funds and the Owners given
within 20 days after the Company provides such notice (which request shall
specify the number Registrable Shares intended to be disposed of by each RDC
Fund and such responding Owner and the intended method of disposition thereof),
the Company, subject to the provisions hereof, shall use commercially reasonable
efforts to cause all Registrable Shares which the Company has been requested by
the RDC Funds and the Owners to register to be registered under the Securities
Act to the extent necessary to permit their sale or other disposition in
accordance with the intended methods of distribution specified in the request of
the RDC Funds and the Owners; provided, that the Company shall have the right to
postpone or withdraw any registration effected pursuant to this Section 2(a)
hereof without obligation or liability to the RDC Funds and the Owners.

             (b) In connection with any offering under this Section 2 involving
an underwriting, the Company shall not be required to include any Registrable
Shares in such underwriting unless the Participating Holders accept the terms of
the underwriting as agreed upon between the Company and the underwriters
selected by it, and then only in such quantity as will not, in the opinion of
the underwriters, jeopardize the success of the offering by and for the account
of the

                                        2

Company. If, in the opinion of the managing underwriter, the registration of
all, or part of, theRegistrable Shares which the holders thereof have requested
be included would materially and adversely affect such public offering, then the
Company shall be required to include in the underwriting only that number of
Registrable Shares, if any, which the managing underwriter believes may be sold
without causing such material and adverse effect. If the number of Registrable
Shares to be included in the underwriting in accordance with the foregoing is
less than the total number of Registrable Shares which the holders thereof have
requested be included, then the holders of the Registrable Shares shall
participate in the underwriting pro rata based upon the relative number of
Shares each holder of such other securities has requested be included in such
registration; provided, however, that nothing herein shall be construed to
modify or otherwise impair or limit the rights of any holder of Shares or other
person to whom registration rights have been granted by the Company prior to the
date hereof and where such rights would be superior to the rights of the Holders
of Registrable Shares.

          3. Demand Registration Rights. Upon the request of either (i) the RDC
Funds or (ii) the Owners owning of record not less than sixty-five percent (65%)
of the Registrable Shares owned of record by all Owners (the "Demanding
Holders"), subject to the provisions hereof, the Company will use commercially
reasonable efforts to cause such of the Registrable Shares as may be requested
by the RDC Funds and/or the Demanding Holders to be registered under the
Securities Act as promptly as possible. The Company shall not be required to
effect more than two registrations per year pursuant to this Section 3;
provided, however, that each obligation shall be deemed satisfied when a
Registration Statement covering Registrable Shares specified in notices received
as aforesaid, for sale in accordance with the method of disposition specified by
the RDC Funds and/or the Demanding Holders shall become effective and shall have
remained effective for at least 60 days (provided that if the reason the
Registration Statement does not become effective is as a direct result of the
gross negligence or willful misconduct of any one or more of the RDC Funds or
another Demanding Holder, such attempt at registration shall satisfy the
requirements of a "demand" registration under this Section 3). The Company will
be entitled to include in any registration statement referred to in this Section
3 for sale in accordance with the method of disposition specified above,
securities to be sold by the Company for its own account and securities of any
other holder having registration rights, unless in the opinion of the managing
underwriter (if such method of disposition shall be an underwritten public
offering), such inclusion would materially and adversely affect the marketing of
the Registrable Shares to be sold.

          4. Certain Shelf Registration. In addition to the registration rights
granted by the Company in Sections 2 and 3 hereof, on the Anniversary Date or as
soon thereafter as is reasonably practicable, the Company shall, at its expense,
use commercially reasonable efforts to register the Registrable Shares for
resale including for issuance upon conversion or exchange of OP Units, through a
shelf Registration Statement pursuant to Rule 415 under the Securities Act,
which shelf Registration Statement shall cover only the Registrable Shares. The
Company shall, at its expense, use commercially reasonable efforts to maintain
the effectiveness of such shelf Registration Statement until the earlier of (i)
such time as when all of the Registrable Shares have been disposed of or (ii)
three years after the conversion or exchange of all of the OP Units issued under
the Contribution Agreement into Shares.

          5. Registration Procedures. If and whenever the Company is required by
the  provisions  of this  Agreement  to effect  the  registration  of any of the
Registrable Shares under the Securities Act, the Company shall:

             (a) prepare and file with the Commission a Registration Statement
with respect to such Registrable Shares and use commercially reasonable efforts
to cause that Registration Statement to become and remain effective, provided,
however, that the Company may discontinue any registration of its securities
which is being effected pursuant to Section 2 herein at any time prior to the
effective date of the Registration Statement relating thereto;

             (b) subject to the provision of Section 4, as soon as reasonably
practicable prepare and file with the Commission any amendments and supplements
to the Registration Statement and the prospectus included in the Registration
Statement as may be necessary to keep the Registration Statement effective until
the earlier of (i) the period of time required by the Commission, or (ii) 180
days from the effective date for registrations pursuant to Section 2 and 60 days
from the effective date for registrations pursuant to Section 3;

             (c) as soon as reasonably practicable furnish to each Participating
Holder such reasonable numbers of copies of the prospectus, including a
preliminary prospectus, in conformity with the requirements of the Securities
Act, and such other documents as the Participating Holders may reasonably
request in order to facilitate the public sale or other disposition of the
Registrable Shares owned by such Participating Holders and included in the
Registration Statement;

             (d) as soon as reasonably practicable use commercially reasonable
efforts to register or qualify the Registrable Shares covered by the
Registration Statement under the securities or Blue Sky laws of states within
the United States as the Participating Holders shall reasonably request;
provided, however, that the Company shall not be required in connection with
this subsection 5(d) to: (i) qualify as a foreign corporation in any
jurisdiction where, but for the requirements of this subsection 5(d), it would
not be obligated to be so qualified; (ii) execute a general consent to service
of process in any jurisdiction; (iii) subject itself to taxation in any such
jurisdiction; or (iv) register in any state requiring, as a condition to
registration, escrow or surrender of any Company securities held by any security
holder other than the Participating Holders; and

             (e) if an underwritten public offering, obtain a comfort letter
from the Company's independent public accountants in customary form and covering
such matters of the type customarily covered by comfort letters and an opinion
from the Company's counsel in the form filed as an exhibit to the Registration
Statement, in each case addressed to the Participating Holders.

          If the Company has delivered a preliminary or final prospectus to a
Participating Holder and, after having done so, the prospectus is amended to
comply with the requirements of the Securities Act, the Company shall promptly
notify such Participating Holder and, if requested, such Participating Holder
shall immediately cease making offers of Registrable Shares and return all
prospectuses to the Company. The Company shall promptly provide Participating
Holders with revised prospectuses and, following receipt of the revised
prospectuses, Participating Holders shall be free to resume making offers of the
Registrable Shares.

          Notwithstanding any other provisions of this Agreement to the
contrary, upon receipt by a Participating Holder of a written notice signed by
the Chief Executive Officer, Chief Operating Officer or Chief Financial Officer
of the Company, to the effect set forth below, the Company shall not be
obligated during a reasonable period of time thereafter to effect any
registrations pursuant to this Agreement, and each such Participating Holder
agrees that it will immediately suspend sales of Shares under any effective
Registration Statement for a reasonable period of time, in either case not to
exceed 90 days, at any time during which, in the Company's reasonable judgment,
(i) there is a development involving the Company or any of its affiliates which
is material but which has not yet been publicly disclosed or (ii) sales pursuant
to the Registration Statement would materially and adversely affect an unwritten
public offering for the account of the Company or any other material financing
project where a proposed or pending material merger or other material
acquisition or material business combination or material disposition of the
Company's assets, to which the Company or any of its affiliates is, or is
expected to be, a party. In the event a registration is postponed or sales by a
Participating Holder pursuant to an effective Registration Statement are
suspended in accordance with this paragraph, there shall be added to the period
during which the Company is obligated keep a Registration Statement effective
the number of days for which the Registration Statement was postponed or sales
were suspended.

          6. Expenses of Registration. The Company will pay all Registration
Expenses of all registrations under this Agreement. For purposes of this
Agreement, the term "Registration Expenses" shall mean all expenses incurred by
the Company in complying with this Agreement, including without limitation, all
registration and filing fees, exchange listing fees, printing expenses, the fees
and disbursements of counsel for the Company and the reasonable fees and
disbursements of one counsel selected by the Participating Holders, the fees and
disbursements of the Company's accountants, state Blue Sky fees and expenses,
and the expense of any special audits incident to or required by any such
registration, but excluding underwriting discounts and selling commissions.

          7. Indemnification.

             (a) Indemnification of Participating Holders. In the event of any
registration of any of the Registrable Shares under the Securities Act pursuant
to this Agreement, the Company will indemnify and hold harmless each
Participating Holder, each of its directors and officers and each other person,
if any, who controls such Participating Holder within the meaning of the
Securities Act or the Exchange Act, against any losses, claims, damages or
liabilities to which such Participating Holder or controlling person may become
subject under the Securities Act, the Exchange Act, Blue Sky laws or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in any Registration Statement under
which such Registrable Shares were registered under the Securities Act, any
preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or supplement to such Registration Statement, or
arise out of or are based upon the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading;
and the Company will reimburse such Participating Holder and each such
controlling person for any legal or any other expenses reasonably incurred by
such Participating Holder or controlling person in connection with investigating
or defending any such loss, claim, damage, liability or action; provided,
however, that the Company will not be liable in any such case to

743441.2
                                        5

<PAGE>



             the extent that any such loss, claim, damage or liability arises
out of or is based upon any untrue statement or omission made in such
Registration Statement, preliminary prospectus or prospectus, or any such
amendment or supplement, in reliance upon and in conformity with information
furnished to the Company, in writing, by or on behalf of any Participating
Holder or controlling person specifically for use in the preparation thereof;
and provided further, however, that any indemnification contained in this
paragraph with respect to any preliminary prospectus shall not inure to the
benefit of any person who otherwise is entitled to indemnification hereunder on
account of any loss, liability, claim, damage or expense if a copy of an amended
or supplemental preliminary prospectus, or the final prospectus, shall have been
delivered or sent to such person within the time required by the Securities Act,
and the untrue statement or omission of a material fact was corrected in such
amended or supplemental preliminary prospectus or final prospectus and provided
that such person did not deliver such amended or supplemental preliminary
prospectus or final prospectus on a timely basis.

             (b) Indemnification of the Company. In the event of any
registration of any of the Registrable Shares under the Securities Act pursuant
to this Agreement, each Participating Holder will indemnify and hold harmless
the Company, each of its directors and officers and each person, if any, who
controls the Company within the meaning of the Securities Act or the Exchange
Act, against any losses, claims, damages or liabilities, joint or several, to
which the Company, such directors and officers or controlling persons may become
subject under the Securities Act, Exchange Act, Blue Sky laws or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of a material fact contained in any Registration Statement under which
such Registrable Shares were registered under the Securities Act, any
preliminary prospectus or final prospectus contained in the Registration
Statement, or any amendment or supplement to the Registration Statement, or
arise out of or are based upon any omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading,
if the statement or omission was made in reliance upon and in conformity with
information furnished in writing to the Company by or on behalf of such
Participating Holder or controlling person, specifically for use in connection
with the preparation of such Registration Statement, prospectus, amendment or
supplement. No Participating Holder shall be liable pursuant to this Section
7(b) for any amount in excess of the proceeds of the offering received by such
Participating Holder.

             (c) Notice of Claim. Each party entitled to indemnification under
this Section 7 (the "Indemnified Party") shall give notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such claim or any litigation resulting therefrom; provided that counsel for the
Indemnifying Party, who shall conduct the defense of such claim or litigation,
shall be approved by the Indemnified Party (whose approval shall not be
unreasonably withheld); and, provided, further, that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Section 7 unless the failure to
provide such notice materially prejudices the defense by the Indemnifying Party
against such claim. The Indemnified Party may participate in such defense at
such party's expense (provided that the counsel of the Indemnifying Party shall
control the defense of such claim or proceeding); provided, however, that the
Indemnifying Party shall pay such expense if representation of such Indemnified
Party by the counsel retained by the Indemnifying Party would, in the opinion of
counsel of the Indemnified Party, be inappropriate due to actual or potential

743441.2
                                        6

<PAGE>



differing interests between the Indemnified Party and any other party
represented by such counsel in such proceeding, it being understood, however,
that in such event, the Indemnifying Party shall be liable for the reasonable
fees and expenses of only one counsel for the Indemnified Parties. No
Indemnifying Party, in the defense of any such claim or litigation shall as to
an Indemnified Party, except with the consent of such Indemnified Party, consent
to entry of any judgment or enter into any settlement which does not include as
an unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect of such claim or
litigation, and no Indemnified Party shall consent to entry of any judgment or
settle such claim or litigation without the prior written consent of the
Indemnifying Party.

          8. Underwriting Agreement. In the event that Registrable Shares are
sold pursuant to a Registration Statement in an underwritten offering, each
Participating Holder agrees to enter into an underwriting agreement in customary
form with the underwriter or underwriters selected for the underwriting
(together with the Company and other holders of securities distributing their
Shares through such underwriting), containing customary representations and
warranties with respect to such Participating Holder, including without
limitation, customary provisions with respect to indemnification by such
Participating Holder of the underwriters of such offering.

          9. Rule 144. The Company covenants that it will file the reports
required to be filed by it under the Securities Act and the Exchange Act and the
rules and regulations adopted by the Commission thereunder (or, if the Company
is not required to file such reports, it will, upon the request of the holders
of the Registrable Securities, make publicly available such information as
necessary to permit sales pursuant to Rule 144 under the Securities Act) and it
will do all such other acts and things from time to time as reasonably requested
by the holders of the Registrable Securities to the extent required from time to
time to enable the holders of the Registrable Shares to sell Registrable Shares
without registration under the Securities Act within the limitation of the
exemptions provided by Rule 144 under the Securities Act, as such Rule may be
amended from time to time, or any similar rule or regulation hereunder adopted
by the Commission.

          10. Cooperation. The Holders shall furnish to the Company such
information regarding the Holders and the distribution proposed by Participating
Holders as the Company may from time to time request in writing, and shall do
such reasonable acts and things as the Company may from time to time request,
with respect to any registration, qualification or compliance referred to in
this Agreement and in order to permit the Company to comply with the
requirements of law. Any failure by a Holder to make available such information
or to do such acts and things shall constitute a waiver by such Holder of its
rights to include such Holder's Registrable Shares in any such registration.

          11. Standstill. Each Holder, if requested by the Company and an
underwriter of Shares or other securities of the Company, shall agree not to
sell or otherwise transfer or dispose of any Registrable Shares or other
securities of the Company held by such Holder for a specified period of time
(not to exceed 180 days) following the effective date of a Registration
Statement. Such agreement shall be in writing in a form satisfactory to the
Company and such underwriter. The Company may impose stop transfer instructions
with respect to the Registrable Shares or other securities subject to the
foregoing restriction until the end of the standstill period.


743441.2
                                        7

<PAGE>



          12. Restriction on Resale. Unless otherwise agreed by the Company,
until the date on which there are no Registrable Shares, each Holder agrees that
it will not resell such Registrable Shares without registration under the
Securities Act, compliance with Rule 144 under the Securities Act or an opinion
of counsel for the Company, addressed to the Company, to the effect that no such
registration is required. All reasonable costs, fees and expenses of counsel in
connection with such opinion shall be borne by the Company.

          13. Lock-Up Agreement. In consideration of the Company's agreement to
provide the Holders with the registration rights as set forth in this Agreement,
each RDC Fund and each Contributing Owner receiving OP Units or Shares agrees
with the Partnership and the Trust that each will not sell, transfer, assign, or
otherwise transfer the OP Units or the Shares to be issued at the Closing (or
Conversion Shares) for one year after the Closing. Notwithstanding the
foregoing, the aforementioned prohibition shall not apply to a transfer of OP
Units (which shall nonetheless comply with any requirements or conditions to
transfer in the Partnership Agreement of the Partnership) or Shares to a
Permitted Transferee or bona fide pledge of OP Units or Shares (provided that
the pledgee agrees to be bound by the terms of this Agreement as if an original
signatory thereto). For purposes of this Section 13, the term "Permitted
Transferees" means (i) any partner or other equity owner of an RDC Fund or an
Owner; (ii) any equity owner of any partner or other equity owner of an RDC Fund
or an Owner; (iii) members of the Immediate Family (as defined below) of any
equity owner of an RDC Fund or an Owner (or any equity thereof) and trusts for
the benefit of one or more members of the Immediate Family of an RDC Fund or an
Owner (or any equity owner thereof) created for estate and/or gift tax purposes
and/or (iv) any public charity, public foundation or charitable institution as
defined in Section 501(c)(3) of the Internal Revenue Code of 1986, as amended.
For purposes of this Section 13, the term "Immediate Family" means, with respect
to any natural person, such natural person's spouse, parents, parents-in-law,
descendants, nephews, nieces, brothers, sisters, brothers-in- law,
sisters-in-law and children-in-law. A transfer to any Permitted Transferee shall
not be deemed effective, and the Company may issue stop transfer instructions to
its transfer agent of the Shares in connection with a purported transfer, unless
and until the transferor shall give the Company written notice stating the name
and address of the Permitted Transferee and identifying the securities which are
being transferred and the Company shall have received the written agreement of
the Permitted Transferee to be bound by the terms of this Agreement as if an
original signatory hereto.

          14. Miscellaneous.

             (a) Controlling Law. This Agreement shall be governed by and
construed in accordance with the laws of the Commonwealth of Pennsylvania.

             (b) Notices. All notices and other communications hereunder shall

                      (ii)   If to a Holder, to the address of such Holder
                             appearing below the Holder's signature on the
                             signature page hereof:

          Any party may alter the address to which communications or copies are
to be sent by giving notice of such change of address in conformity with the
provisions of this paragraph for the giving of notice. Notices given hereunder
shall be deemed received upon actual receipt thereof or, in the case of notice

the manner provided above

             (c) Binding Nature of Agreement. This Agreement shall be binding
upon and inure to the benefit of Company and its successors and assigns and
shall be binding upon each Holder and its heirs, personal properties, successors
and assigns.

             (d) Transfer or Assignment of Registration Rights. Subject to
Section 13 hereof, the rights with respect to any Registrable Shares to cause
the Company to register such securities granted to a Holder by the Company under
this Agreement may be transferred or assigned by a Holder, in whole or in part,
to a transferee or assignee of any Registrable Shares (or any OP Units which are
convertible, exercisable or redeemable, directly or indirectly, for Registrable
Shares); provided that, in such case, the Company shall be given written notice
stating the name and address of said transferee or assignee and identifying the
securities with respect to which such registration rights are being transferred
or assigned and the Company shall have received the written agreement of such
transferee or assignee to be bound by the terms of this Agreement.

             (e) Execution in Counterparts. This Agreement may be executed in
any number of counterparts, each of which shall be deemed to be an original as
against any party whose signature appears thereon, and all of which shall
together constitute one and the same instrument. This Agreement shall become
binding when one or more counterparts hereof, individually taken together, shall
bear the signatures of all of the parties reflected hereon as the signatories.

             (f) Provisions Separable. The provisions of this Agreement are
independent of and separable from each other, and no provision shall be affected
or rendered invalid or unenforceable by virtue of the fact that for any reason
any other or others of them may be invalid or unenforceable in whole or in part.

             (g) Entire Agreement. This Agreement contains the entire
understanding among the parties hereto with respect to the subject matter
hereof, and supersedes all prior and contemporaneous agreements and
understandings, inducements or conditions, express or implied, oral or written,
except as herein contained. This Agreement may not be modified or amended other
than by an agreement in writing.

                    REGISTRATION RIGHTS AND LOCK-UP AGREEMENT

                            (Pacesetter Transaction)


                    REGISTRATION RIGHTS AND LOCK-UP AGREEMENT


          THIS REGISTRATION RIGHTS AND LOCK-UP AGREEMENT (this "Agreement"),  is
made and entered into as of November __, 1999, by and among Acadia Realty Trust,
a Maryland  business trust (the "REIT"),  Acadia Realty Limited  Partnership,  a
Delaware limited partnership (the  "Partnership"),  and the undersigned partners
(each,  a  "Pacesetter  Partner") of  Pacesetter/Ramapo  Associates,  a New York
limited partnership  ("Associates"),  which, at the Closing (the "Closing Date")
of the transactions contemplated by the Purchase and Sale Agreement by and among
Associates,  the REIT, the  Partnership and Acadia  Pacesetter  LLC., a Delaware
limited liability company (the "Purchase  Agreement"),  are receiving  preferred
units of limited  partnership  interests in the Partnership  ("Preferred Units")
which are convertible into common units of limited  partnership  interest in the
Partnership ("OP Units"),  which in turn, are exchangeable for Conversion Shares
(as defined below).

          NOW,  THEREFORE,  in  consideration  of the  premises  and the  mutual
covenants  contained herein, and intending to be legally bound hereby, the REIT,
the Partnership and each of the Pacesetter Partners hereby agree as follows:

          1. Certain Definitions. As used in this Agreement, the following terms
shall have the following respective meanings:

             (a) "Commission" means the Securities and Exchange  Commission,  or
any other federal agency at the time administering the Securities Act.

             (b) "Conversion  Shares" means the Shares issuable upon exchange of
the OP Units from time to time.

             (c) "Exchange  Act" means the  Securities  Exchange Act of 1934, as
amended, or any successor federal statute,  and the rules and regulations of the
Commission  issued under such Exchange Act, as they each may, from time to time,
be in effect.

             (d)  "Holder(s)"  means a holder of Registrable  Shares entitled to
the rights arising hereunder.

             (e) "Participating  Holder" means a Holder whose Registrable Shares
are included in a Registration Statement.

             (f) "Registration Expenses" means the expenses described in Section
4 hereof.

             (g) "Registration  Statement" means a registration  statement filed
by the  REIT  with  the  Commission  for a public  offering  and sale of  equity
securities of the REIT (other than a registration  statement on Form S-8 or Form
S-4, or their successors, or any registration statement covering only securities
proposed  to  be  issued  in  exchange  for  securities  or  assets  of  another
corporation).

             (h) "Registrable  Shares" means (i) the Conversion Shares, (ii) any
other Shares issued in respect of Conversion  Shares, and (iii) any other Shares
issued with  respect to the Shares  issued in clauses  (i) and (ii)  (because of
share splits, share dividends, reclassifications,  recapitalizations, or similar
events); provided, however, that Shares which are Registrable Shares shall cease
to be Registrable Shares

(x) upon any sale  pursuant to a  Registration  Statement,  or any other sale or
transfer of the  Registrable  Shares in any manner to any person or entity other
than a Permitted  Transferee  (as  defined) or as otherwise  expressly  provided
herein,  or (y) in the event that  Registrable  Shares may be freely sold and/or
transferred pursuant to Rule 144(k) under the Securities Act.

             (i) "Securities  Act" means the Securities Act of 1933, as amended,
or  any  successor  federal  statute,  and  the  rules  and  regulations  of the
Commission  issued  under such  Securities  Act, as they each may,  from time to
time, be in effect.

             (j) "Shares"  means  Common  Shares of  Beneficial  Interest of the
REIT, par value $.001 per share.

          2. Certain Shelf Registration.  Upon the written request of any Holder
given no sooner than 90 days prior to the end of the Lock-Up  Period (as defined
herein),  the REIT  shall,  at any time or, from time to time,  at its  expense,
register  the  Registrable   Shares  for  resale  including  for  issuance  upon
conversion  or  exchange  of OP Units,  through a shelf  Registration  Statement
pursuant to Rule 415 under the Securities Act, which the REIT shall use its best
efforts to file within 90 days after the receipt of the request by such  Holder.
The REIT shall, at its expense, use commercially  reasonable efforts to maintain
the effectiveness of such shelf Registration  Statement until the earlier of (i)
such time as when all of the  Registrable  Shares have been  disposed of or (ii)
three years after the  conversion or exchange into Shares of all of the OP Units
issued  upon  conversion  of the  Preferred  Units  issued  under  the  Purchase
Agreement.

          3.  Registration  Procedures.  If and whenever the REIT is required by
the  provisions  of this  Agreement  to effect  the  registration  of any of the
Registrable Shares under the Securities Act, the REIT shall, at its expense:

             (a) prepare and file with the Commission a  Registration  Statement
with  respect  to such  Registrable  Shares  and use best  efforts to cause that
Registration Statement to become effective;

             (b) use commercially  reasonable  efforts to cause the Registration
Statement to remain effective;

             (c) subject to the  provision  of Section 2,  promptly  prepare and
file with the  Commission any  amendments  and  supplements to the  Registration
Statement and the prospectus  included in the  Registration  Statement as may be
necessary to keep the  Registration  Statement  effective for the period of time
required by the Commission;

             (d) promptly furnish to each  Participating  Holder such reasonable
numbers of copies of the  prospectus,  including a  preliminary  prospectus,  in
conformity with the requirements of the Securities Act, and such other documents
as the Participating  Holders may reasonably  request in order to facilitate the
public  sale or  other  disposition  of the  Registrable  Shares  owned  by such
Participating Holders and included in the Registration Statement; and

             (e)   promptly   use  best  efforts  to  register  or  qualify  the
Registrable Shares covered by the Registration Statement under the securities or
Blue Sky laws of states  within the United States as the  Participating  Holders
shall reasonably request; provided, however, that the REIT shall not be required
in connection with this subsection 3(d) to: (i) qualify as a foreign corporation
in any jurisdiction  where, but for the requirements of this subsection 3(d), it
would not be obligated to be so qualified; (ii)

780228.7
                                      - 2 -

<PAGE>



execute a general  consent to service  of  process  in any  jurisdiction;  (iii)
subject  itself to taxation in any such  jurisdiction;  or (iv)  register in any
state requiring, as a condition to registration, escrow or surrender of any REIT
securities held by any security holder other than the Participating Holders.

          If the REIT has  delivered  a  preliminary  or final  prospectus  to a
Participating  Holder and,  after having done so, the  prospectus  is amended to
comply with the  requirements  of the  Securities  Act, the REIT shall  promptly
notify such Participating  Holder and, if requested,  such Participating  Holder
shall  immediately  cease  making  offers of  Registrable  Shares and return all
prospectuses to the REIT. The REIT shall promptly provide  Participating Holders
with revised  prospectuses and,  following receipt of the revised  prospectuses,
Participating  Holders shall be free to resume making offers of the  Registrable
Shares.

          Notwithstanding   any  other  provisions  of  this  Agreement  to  the
contrary,  upon receipt by a Participating  Holder of a written notice signed by
the Chief Executive Officer,  Chief Operating Officer or Chief Financial Officer
of the REIT,  to the effect  set forth  below,  the REIT shall not be  obligated
during a  reasonable  period  of time  thereafter  to effect  any  registrations
pursuant to this Agreement,  and each such  Participating  Holder agrees that it
will  immediately  suspend  sales of  Shares  under any  effective  Registration
Statement for a reasonable period of time, in either case not to exceed 90 days,
at any time during  which,  in the REIT's  reasonable  judgment,  (i) there is a
development  involving the REIT or any of its  affiliates  which is material but
which  has  not yet  been  publicly  disclosed  or (ii)  sales  pursuant  to the
Registration  Statement  would  materially and adversely  affect an underwritten
public  offering  for the  account of the REIT or any other  material  financing
project  or where a  proposed  or  pending  material  merger  or other  material
acquisition  or material  business  combination  or material  disposition of the
REIT's assets,  to which the REIT or any of its affiliates is, or is expected to
be,  a  party.  In  the  event  a  registration  is  postponed  or  sales  by  a
Participating  Holder  pursuant  to  an  effective  Registration  Statement  are
suspended in accordance with this paragraph,  there shall be added to the period
during which the REIT is obligated to keep a  Registration  Statement  effective
the number of days for which the  Registration  Statement was postponed or sales
were suspended.

          4.  Expenses  of  Registration.  The REIT  will  pay all  Registration
Expenses  of all  registrations  under  this  Agreement.  For  purposes  of this
Agreement,  the term "Registration Expenses" shall mean all expenses incurred by
the REIT in complying with this Agreement,  including  without  limitation,  all
registration and filing fees, exchange listing fees, printing expenses, the fees
and  disbursements  of  counsel  for  the  REIT  and  the  reasonable  fees  and
disbursements of one counsel selected by the Participating Holders, the fees and
disbursements of the REIT's accountants,  state Blue Sky fees and expenses,  and
the  expense  of  any  special  audits  incident  to or  required  by  any  such
registration, but excluding underwriting discounts and selling commissions.

          5.  Indemnification.

             (a)  Indemnification of Participating  Holders. In the event of any
registration of any of the Registrable  Shares under the Securities Act pursuant
to this Agreement,  the REIT will indemnify and hold harmless each Participating
Holder,  each of its directors  and officers and each other person,  if any, who
controls such  Participating  Holder within the meaning of the Securities Act or
the Exchange Act,  against any losses,  claims,  damages or liabilities to which
such  Participating  Holder or  controlling  person may become subject under the
Securities  Act, the Exchange Act,  Blue Sky laws or otherwise,  insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue  statement  or alleged  untrue  statement of any
material  fact  contained  in  any  Registration   Statement  under  which  such
Registrable Shares were registered under the Securities Act, any

780228.7

preliminary  prospectus  or  final  prospectus  contained  in  the  Registration
Statement,  or any amendment or supplement to such  Registration  Statement,  or
arise out of or are based  upon the  omission  or  alleged  omission  to state a
material fact required to be stated  therein or necessary to make the statements
therein,  in light of the circumstances in which they were made, not misleading;
and the REIT will reimburse such Participating  Holder and each such controlling
person  for  any  legal  or any  other  expenses  reasonably  incurred  by  such
Participating  Holder or controlling  person in connection with investigating or
defending any such loss, claim, damage, liability or action; provided,  however,
that the REIT will not be liable  in any such case to the  extent  that any such
loss,  claim,  damage or  liability  arises  out of or is based  upon any untrue
statement  or  omission  made  in  such  Registration   Statement,   preliminary
prospectus or prospectus,  or any such amendment or supplement, in reliance upon
and in conformity with information  furnished to the REIT, in writing,  by or on
behalf of any Participating Holder or controlling person specifically for use in
the preparation thereof; and provided further, however, that any indemnification
contained in this paragraph with respect to any preliminary prospectus shall not
inure to the benefit of any person who otherwise is entitled to  indemnification
hereunder on account of any loss, liability,  claim, damage or expense if a copy
of an amended or supplemental  preliminary prospectus,  or the final prospectus,
shall have been delivered or sent to such person within the time required by the
Securities  Act,  and the untrue  statement  or omission of a material  fact was
corrected  in such  amended  or  supplemental  preliminary  prospectus  or final
prospectus  and  provided  that such  person  did not  deliver  such  amended or
supplemental preliminary prospectus or final prospectus on a timely basis.

             (b)  Indemnification  of the REIT. In the event of any registration
of any of the  Registrable  Shares  under the  Securities  Act  pursuant to this
Agreement,  each Participating Holder will indemnify and hold harmless the REIT,
each of its  directors  and officers  and each person,  if any, who controls the
REIT within the meaning of the Securities  Act or the Exchange Act,  against any
losses,  claims,  damages or liabilities,  joint or several,  to which the REIT,
such directors and officers or controlling  persons may become subject under the
Securities  Act,  Exchange  Act,  Blue Sky laws or  otherwise,  insofar  as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based  upon any untrue  statement  or alleged  untrue  statement  of a
material  fact  contained  in  any  Registration   Statement  under  which  such
Registrable  Shares were  registered  under the Securities  Act, any preliminary
prospectus or final prospectus contained in the Registration  Statement,  or any
amendment or supplement to the  Registration  Statement,  or arise out of or are
based upon any omission or alleged omission to state a material fact required to
be stated therein or necessary to make the statements  therein,  in light of the
circumstances in which they were made, not misleading, in each case only if such
statement  or  omission  was  made  in  reliance  upon  and in  conformity  with
information  furnished  in  writing  to  the  REIT  by  or  on  behalf  of  such
Participating  Holder or controlling person,  specifically for use in connection
with the preparation of such Registration  Statement,  prospectus,  amendment or
supplement.  No  Participating  Holder shall be liable  pursuant to this Section
5(b) for any amount in excess of the proceeds of the  offering  received by such
Participating Holder.

             (c) Notice of Claim. Each party entitled to  indemnification  under
this Section 5 (the "Indemnified Party") shall give notice to the party required
to  provide  indemnification  (the  "Indemnifying  Party")  promptly  after such
Indemnified Party has actual knowledge of any claim as to which indemnity may be
sought,  and shall  permit the  Indemnifying  Party to assume the defense of any
such claim or any litigation resulting therefrom;  provided that counsel for the
Indemnifying  Party,  who shall conduct the defense of such claim or litigation,
shall  be  approved  by the  Indemnified  Party  (whose  approval  shall  not be
unreasonably  withheld);  and,  provided,  further,  that  the  failure  of  any
Indemnified  Party to give  notice as  provided  herein  shall not  relieve  the
Indemnifying Party of its obligations under this Section 5 unless the failure to
provide such notice materially prejudices the defense by the Indemnifying Party

against such claim.  The  Indemnified  Party may  participate in such defense at
such party's expense (provided that the counsel of the Indemnifying  Party shall
control the defense of such claim or proceeding);  provided,  however,  that the
Indemnifying  Party shall pay such expense if representation of such Indemnified
Party by the counsel retained by the Indemnifying Party would, in the opinion of
counsel of the Indemnified  Party, be  inappropriate  due to actual or potential
differing   interests   between  the  Indemnified  Party  and  any  other  party
represented by such counsel in such proceeding,  it being  understood,  however,
that in such event,  the  Indemnifying  Party shall be liable for the reasonable
fees  and  expenses  of  only  one  counsel  for  the  Indemnified  Parties.  No
Indemnifying  Party, in the defense of any such claim or litigation  shall as to
an Indemnified Party, except with the consent of such Indemnified Party, consent
to entry of any judgment or enter into any settlement  which does not include as
an  unconditional  term  thereof the giving by the claimant or plaintiff to such
Indemnified  Party of a release  from all  liability in respect of such claim or
litigation,  and no Indemnified  Party shall consent to entry of any judgment or
settle  such  claim or  litigation  without  the prior  written  consent  of the
Indemnifying Party.

          6. Rule 144. The REIT covenants that it will file the reports required
to be filed by it under the  Securities  Act and the  Exchange Act and the rules
and  regulations  adopted by the Commission  thereunder  (or, if the REIT is not
required to file such reports,  it will,  upon the request of the holders of the
Registrable Securities, make publicly available such information as necessary to
permit sales pursuant to Rule 144 under the  Securities  Act) and it will do all
such other  acts and things  from time to time as  reasonably  requested  by the
holders of the  Registrable  Securities to the extent required from time to time
to enable  the  holders of the  Registrable  Shares to sell  Registrable  Shares
without  registration  under the  Securities  Act within the  limitation  of the
exemptions  provided by Rule 144 under the  Securities  Act, as such Rule may be
amended from time to time, or any similar rule or regulation  hereunder  adopted
by the Commission.

          7. Cooperation. The Holders shall furnish to the REIT such information
regarding the Holders and the distribution  proposed by Participating Holders as
the REIT may from time to time reasonably request in writing,  and shall do such
reasonable  acts and  things  as the REIT may from  time to time  request,  with
respect to any  registration,  qualification  or compliance  referred to in this
Agreement  and in order to permit the REIT to comply  with the  requirements  of
law. Any failure by a Holder to make  available  such  information or to do such
acts and  things  shall  constitute  a waiver by such  Holder  of its  rights to
include such Holder's Registrable Shares in any such registration.

          8.  Standstill.   Each  Holder,  if  requested  by  the  REIT  and  an
underwriter of Shares or other  securities of the REIT,  shall agree not to sell
or otherwise  transfer or dispose of any Registrable  Shares or other securities
of the REIT held by such Holder for a specified period of time (not to exceed 90
days) following the effective date of a Registration  Statement.  Such agreement
shall be in writing in a form satisfactory to the REIT and such underwriter. The
REIT may impose  stop  transfer  instructions  with  respect to the  Registrable
Shares or other securities subject to the foregoing restriction until the end of
the standstill period.

          9.  Restriction on Resale.  Unless otherwise agreed by the REIT, until
the date on which there are no  Registrable  Shares,  each Holder agrees that it
will  not  resell  such  Registrable  Shares  without   registration  under  the
Securities Act,  compliance with Rule 144 under the Securities Act or an opinion
of counsel for such Holder reasonably  acceptable to the REIT,  addressed to the
REIT, to the effect that no such registration is required. All reasonable costs,
fees and expenses of counsel in  connection  with such opinion shall be borne by
the REIT.

          10. Lock-Up  Agreement.  In  consideration  of the REIT's agreement to
provide the Holders with the registration rights as set forth in this Agreement,
each of the Pacesetter Partners agrees with the REIT and the Partnership that it
will not sell,  assign,  or otherwise  transfer the OP Units to be issued at the
Closing  (or  Conversion  Shares)  for a period  of one year  commencing  on the
Closing  Date  (the  "Lock-Up  Period").   Notwithstanding  the  foregoing,  the
aforementioned  prohibition shall not apply to (x) conversion to OP Units; (y) a
transfer of OP Units (which shall  nonetheless  comply with any  requirements or
conditions  to transfer in the  Partnership  Agreement  of the  Partnership)  or
Conversion Shares to a Permitted Transferee; or (z) bona fide pledge of OP Units
or Conversion  Shares (provided that the pledgee agrees to be bound by the terms
of this  Agreement as if an original  signatory  thereto).  For purposes of this
Section  10, the term  "Permitted  Transferees"  means (i) any  partner or other
equity  owner of the  Partnership  or  Associates;  (ii) any equity owner of any
partner or other equity owner of the Partnership or Associates; (iii) members of
the Immediate  Family (as defined below) of any person described in (i) or (ii);
and (iv) trusts for the benefit  of, or entities  controlled  by, one or more of
the persons  described  in (i),  (ii) or (iii);  and/or (v) any public  charity,
public  foundation or charitable  institution as defined in Section 501(c)(3) of
the Internal Revenue Code of 1986, as amended.  For purposes of this Section 10,
the term  "Immediate  Family" means,  with respect to any natural  person,  such
natural person's spouse, parents, parents-in-law,  descendants, nephews, nieces,
brothers,   sisters,   brothers-in-law,   sisters-in-law  and  children-  in-law
(including adopted persons). A transfer to any Permitted Transferee shall not be
deemed  effective,  and the REIT may issue  stop  transfer  instructions  to its
transfer agent of the Shares in connection with a purported transfer, unless and
until the  transferor  shall give the REIT written  notice  stating the name and
address of the Permitted  Transferee and  identifying  the securities  which are
being  transferred and the REIT shall have received the written agreement of the
Permitted  Transferee  to be  bound  by the  terms  of this  Agreement  as if an
original signatory hereto.

          11. Miscellaneous.

             (a)  Controlling  Law.  This  Agreement  shall be  governed  by and

upon and inure to the benefit of (i) the REIT and its successors and assigns and
(ii) each Holder and its heirs, successors and assigns.

             (b)  Transfer or  Assignment  of  Registration  Rights.  Subject to
Section 10 hereof,  the rights with respect to any  Registrable  Shares to cause
the REIT to register such securities  granted to a Holder by the REIT under this
Agreement may be transferred or assigned by a Holder,  in whole or in part, to a
transferee  or  assignee  of any  Registrable  Shares (or any OP Units which are
convertible,  exercisable or redeemable, directly or indirectly, for Registrable
Shares);  provided  that, in such case,  the REIT shall be given written  notice
stating the name and address of said  transferee or assignee and identifying the
securities with respect to which such registration  rights are being transferred
or  assigned  and the REIT shall have  received  the written  agreement  of such
transferee or assignee to be bound by the terms of this Agreement.

             (c) Execution in  Counterparts.  This  Agreement may be executed in
any number of  counterparts,  each of which shall be deemed to be an original as
against  any party  whose  signature  appears  thereon,  and all of which  shall
together  constitute one and the same  instrument.  This Agreement  shall become
binding when one or more counterparts hereof, individually taken together, shall
bear the signatures of all of the parties reflected hereon as the signatories.

             (d)  Provisions  Separable.  The  provisions of this  Agreement are
independent of and separable from each other, and no provision shall be affected
or rendered  invalid or  unenforceable by virtue of the fact that for any reason
any other or others of them may be invalid or unenforceable in whole or in part.

             (e)  Entire   Agreement.   This   Agreement   contains  the  entire
understanding  among the  parties  hereto  with  respect to the  subject  matter
hereof,   and   supersedes   all  prior  and   contemporaneous   agreements  and
understandings,  inducements or conditions, express or implied, oral or written,
except as herein contained.  This Agreement may not be modified or amended other
than by an agreement in writing.
