ITEM 5.           Other Events

         On December 31, 1998, the Registrant  entered into an agreement,  among
the Registrant,  Jack  Wertheimer,  Jr. and Marvin L. Slomowitz (the "Settlement
Agreement")  with respect to certain legal actions brought by Mr.  Wertheimer in
federal  district court and in state court stemming from the  termination of Mr.
Wertheimer's employment with the Registrant.

         The Settlement  Agreement  provides for, among other things, (i) mutual
releases of the parties thereto,  (ii)  indemnification by the Registrant of Mr.
Wertheimer for actions taken by him as an officer of the Registrant  (other than
fraudulent conduct), and (iii) a payment of settlement consideration as follows:
(w)  $1,000,000 by December 31, 1998, (x) $900,000 on or prior to April 1, 1999,
and (y) five (5) annual payments of $200,000 each for a period of five (5) years
commencing January 10, 2000 (the "Annual Payments"). The Annual Payments will be
secured by a standby  letter of credit and are  subject to  acceleration  by Mr.
Wertheimer upon a default of the Registrant.

         Mr.  Wertheimer,  the  former  President  of the  Registrant,  filed  a
complaint  against the  Registrant,  its  Trustees and the  Registrant's  former
in-house General Counsel and Chief Financial  Officer in state court in December
1994,  followed by a complaint in federal  district  court in November 1995. The
federal  complaint,  which, like the state court action, was filed in connection
with the  termination  of Mr.  Wertheimer's  employment,  included  a civil RICO
action in which Mr. Wertheimer alleged that the Board of Trustees conspired with
Mr.  Slomowitz  (the  "Principal  Shareholder")  to terminate  Mr.  Wertheimer's
employment.  Further,  Mr.  Wertheimer  alleged that the  defendants  engaged in
securities  fraud in connection with the  Registrant's  initial public offering,
and that the Principal  Shareholder  had defrauded or overcharged the Registrant
in various corporate  transactions.  The federal complaint sought treble damages
under RICO, as well as damages arising from Mr.  Wertheimer's  alleged  wrongful
termination  of  employment,  invasion of  privacy,  intentional  infliction  of
emotional distress, fraud and misrepresentation. The motions to dismiss the RICO
and tort claims filed by the Registrant and the other defendants were granted in
part and denied in part by the court in December 1996.  Specifically,  the court
dismissed Mr. Wertheimer's claims for wrongful discharge,  fraud, negligence and
misrepresentation,  but declined to dismiss the  remainder of the claims at that
time.  In their  answer to the  federal  complaint,  the  defendants  denied all
allegations of wrongdoing, and the Registrant and the Principal Shareholder also
filed  counterclaims  against Mr.  Wertheimer  alleging that Mr. Wertheimer made
material  misrepresentations  in  connection  with his hiring and  breached  his
employment contract and fiduciary duties to the Registrant.

         On December 31, 1998, the Registrant issued a press release,  a copy of
which is attached hereto as Exhibit 99.1, announcing the Settlement Agreement.

option, deliver notice of nonpayment to Acadia Realty Trust as set forth in

Pennsylvania enter judgment by confession against Acadia.

         THIS PARAGRAPH SETS FORTH A WARRANT OF AUTHORITY FOR AN ATTORNEY TO
CONFESS JUDGMENT AGAINST ACADIA REALTY TRUST. IN GRANTING THIS WARRANT OF
AUTHORITY TO CONFESS JUDGMENT AGAINST ACADIA REALTY TRUST, ACADIA REALTY TRUST

HAS OR MAY HAVE TO PRIOR NOTICE AND AN OPPORTUNITY FOR HEARING UNDER THE
RESPECTIVE CONSTITUTIONS AND LAWS OF THE UNITED STATES AND THE COMMONWEALTH OF
PENNSYLVANIA.

         Upon the occurrence of a default of this Agreement and Acadia Realty
Trust's failure to cure such Default after notice, Acadia hereby irrevocably
authorizes and empowers any attorney of any Court of record in the Commonwealth
of Pennsylvania to appear for and to enter and confess judgment against Acadia

                                        3







         5. Simultaneously with execution of this Agreement, Acadia shall
establish an escrow fund in the amount of $1,000,000 with Battle Fowler LLP as
escrow agent. The escrow fund will collateralize Acadia's obligation to make the
$900,000 payment on April 1, 1999 and the five $200,000 payments and will be
released upon presentation to Wertheimer of a mutually acceptable standby
irrevocable letter of credit to secure the payments that have not yet been made
at the time the letter of credit is provided. The irrevocable letter of credit
shall either have a termination date, or be renewable for a period, coextensive
with the payment obligations hereunder and shall specify a draw down procedure
identical to the payment procedure set forth in Paragraph 4 and Schedule A of
the Escrow Agreement attached hereto as Exhibit A. Additional terms applicable
to the escrow fund are set forth in the Escrow Agreement attached hereto as
Exhibit A. The irrevocable letter of credit shall be obtained from a domestic
commercial bank with a deposit base of at least $500 million. Wertheimer shall
pay the costs or fees associated with obtaining the irrevocable letter of credit
up to a maximum of 1.5% of the amount of the letter of credit. In the event that
the costs or fees associated with obtaining the letter of credit exceed 1.5% of
the letter of credit amount, then Acadia will pay the excess costs or fees if it
still intends to provide a letter of credit. Upon request of Acadia, Wertheimer
agrees to provide to Escrow Agent a written acknowledgment of receipt of the
mutually agreeable irrevocable letter of credit.

         6. In the event of a change in control at Acadia, then every
installment not yet paid under this Agreement shall be accelerated and shall
become immediately due and payable. For purposes of this Agreement, change in
control means the sale or disposition of a majority of Acadia's outstanding
capital stock, property, assets or business; or a third


                                        4





person including a "group" as used in Section 13(d)(3) of the Securities
Exchange Act of 1934 (the "Exchange Act"), becomes the beneficial owner,
directly or indirectly, of 51% or more of the combined voting power of Acadia's
outstanding voting securities; or the consolidation of Acadia with or merger
into any other entity on a basis whereby Acadia is not the surviving entity; or
the consolidation of Acadia as a result of an unaffiliated entity being reverse
merged into Acadia whereby control is changed pursuant to the definitions of
this paragraph.

         7. Wertheimer hereby releases and discharges Acadia Realty Trust (f/k/a
Mark Centers Trust), Marvin L. Slomowitz, Marcia Corporation, Lawrence Longua,
Bernhardt Denmark, Harvey Shanus, Joseph Castle II, John Vincent Weber, Marvin
Levine, Steven Pomerantz, and Joshua Kane (collectively, "Defendants") and each
of their past, present, and future employees, representatives, attorneys,
agents, predecessors, subsidiaries, divisions, affiliates, directors, officers,
shareholders, successors, and assigns, from all claims or causes of action --

or not, and including but not limited to all claims for attorneys' fees and
costs -- which against Defendants he ever had, now has or hereafter may have,
arising out of or based on any event from the beginning of the world to the date
of this Settlement Agreement and General Release.

         8. Wertheimer covenants, agrees, and represents that he has not and
will not file or otherwise initiate any type of proceeding with a governmental
agency based on the subject matter of the Lawsuits.

Marvin L. Slomowitz, in his individual capacity, hereby release and discharge
Wertheimer and his representatives, agents, attorneys, successors, and assigns

unsuspected, and whether involved in the Lawsuits or not, and including, but not
limited to all claims for attorneys' fees and costs -- which against Wertheimer
they ever had, now have or hereafter may have, arising out of or based on any
event from the beginning of the world to the date of this Settlement Agreement
and General Release. Acadia will use reasonable efforts to secure full and
complete general releases for Wertheimer from each of the other Defendants.

         10. While agreeing to compromise and settle this Lawsuit, the parties
deny liability to each other. It is understood and agreed that by entering into
this Settlement Agreement and General Release, the parties in no way admit any
liability to each other. Nothing in this Agreement shall constitute precedent or
evidence in another proceeding, with the exception that this Agreement shall be
admissible evidence in any proceeding to enforce the terms hereof.

         11. Promptly upon execution of this Agreement, counsel for the parties
shall file with the Courts the documents necessary to obtain the dismissal of
the Lawsuits with prejudice.

         12. Wertheimer, on the one hand, and Acadia Realty Trust and Slomowitz,
on the other, each agree that they will not make disparaging remarks about the
other or publicize any statements or opinions concerning Wertheimer's experience
as an officer of Mark Centers Trust.


                                        6





         13. The terms of this Agreement inure to the benefit of, and are
binding upon the heirs, successors, and assigns of the parties hereto, and
Wertheimer's right to receive payments under this Agreement is assignable to
Wertheimer's successors, assigns, and heirs.

         14. Wertheimer acknowledges and agrees that he is liable for and will
pay all taxes for which he personally is responsible under federal and state law
as a result of the payments made to him under this Agreement. Wertheimer shall
defend, indemnify, and hold harmless Acadia for any claim arising from
Wertheimer's failure to pay such taxes when due.

         15. The prevailing party in any lawsuit alleging a breach of this
Agreement shall be entitled to recover the reasonable attorneys' fees and costs
incurred in connection with such a lawsuit. 

         16. The parties to this Agreement acknowledge that they have carefully

them by their attorneys. They warrant and represent that they relied upon their
own judgment and that of their legal counsel regarding the proper, sufficient,
and agreed-upon consideration for the terms and provisions of this Agreement and
that no statement or representation by the other parties or their agents,
employees, officers, directors, or legal representatives has influenced or
induced them to execute this Agreement. 

         17. Acadia's Board of Trustees has approved the terms of this Agreement
and has authorized Acadia to enter into this Agreement. 

         18. This Agreement contains the complete and final agreement between

FOR IMMEDIATE RELEASE         FOR MORE INFORMATION CONTACT:
December 31, 1998             Suzanne R. West, Investor Relations @ 212.421.8830


NEW YORK,  December 31, 1998 -- Acadia Realty Trust (NYSE:AKR), a New York-based
real estate  investment  trust,  formerly  known as Mark Centers Trust  ("MCT"),
announced today that it has resolved a significant litigation exposure.

The  litigation  stemmed from a complaint  filed by a former  officer of MCT who
claimed wrongful termination. The settlement of $2.9 million will be paid over a
period of six years,  with a  significant  portion to be paid in 1998. A Company
spokesperson  noted that the  settlement  is  consistent  with new  management's
original underwriting in connection with its investment in MCT.

According to Kenneth F. Bernstein,  Acadia's President,  "Since assuming control
of MCT in August 1998, new management has  implemented an aggressive  turnaround
policy.  We have actively  sought to resolve  outstanding  problems,  dispose of
non-core and under-performing assets, and take other essential steps to position
Acadia  for  superior  earnings  growth.  The  resolution  of this  longstanding
litigation  is another  tangible  sign to  investors  that we are serious  about
correcting the previous problems that limited the growth of this Company."

Acadia Realty Trust,  headquartered on Long Island,  NY, is a  self-administered
equity real estate  investment trust structured as an UPREIT,  which specializes
in the operation,  management,  leasing,  renovation and acquisition of shopping
centers and multi-family properties.  The Company currently owns and operates 58
properties  totaling  approximately  11.5 million square feet,  primarily in the
eastern half of the United  States.  Acadia's  executive  offices are located in
Manhattan.

within the meaning of the Private  Litigation Reform Act of 1995 and as such may
involve known and unknown risk,  uncertainties and other factors which may cause
the actual  results,  performances  or  achievements  of Acadia to be materially
different from any future results,  performances  or  achievements  expressed or
implied by such  forward-looking  statements.  Such  forward-looking  statements
