                          TRO CONTRIBUTION AGREEMENT

         THIS TRO CONTRIBUTION AGREEMENT (the "Agreement") is made as of the
30th day of July, 1997, by and among PENNSYLVANIA REAL ESTATE INVESTMENT
TRUST, an unincorporated association in business trust form created under
Pennsylvania law pursuant to a Trust Agreement dated December 27, 1960, as
last amended and restated on December 16, 1987 ("PREIT"), PREIT ASSOCIATES,
L.P., a Delaware limited partnership (the "Partnership"), THE RUBIN
ORGANIZATION, INC., a Pennsylvania corporation ("TRO"), THE RUBIN
ORGANIZATION-ILLINOIS, INC., an Illinois corporation ("TRO Illinois" and,
together with TRO, the "Companies" and each, a "Company"), the persons
identified on Schedule A hereto, constituting all of the shareholders of TRO
(collectively, the "Current TRO Shareholders"), and the entities identified on
Schedule B hereto (collectively, the "Former TRO Debtholders," and together
with the Current TRO Shareholders, the "TRO Shareholders"). An index of
defined terms is attached as an appendix hereto.

                                  Background

         PREIT has qualified as a real estate investment trust under Section
856(c) of the Internal Revenue Code of 1986, as amended (the "Code").

         The Companies are engaged in the business of managing and developing,
and providing consulting, brokerage and related services with respect to, real
estate (the "Business").

         PREIT is the sole general partner of the Partnership. PREIT Property
Trust, a Pennsylvania business trust, the beneficial interests in which are
held entirely by PREIT ("PREIT Subsidiary"), is currently the sole limited
partner of the Partnership.

         The Current TRO Shareholders are the record and beneficial owners of
all of the outstanding capital stock of TRO.

         Prior to the closing of the acquisition by the Partnership of TRO
capital stock contemplated herein: (i) TRO shall be recapitalized so that its
capital stock shall consist of Class A Voting Common Shares, par value $.01
per share (the "Voting Common Shares"), Class B Non-Voting Common Shares, par
value $.01 per share (the "Non-Voting Common Shares"), and Convertible
NonParticipating Preferred Shares, par value $.01 per share (the "Preferred
Shares"), each of which is convertible on a one-for-one basis into Non-Voting
Common Shares; (ii) in connection with such recapitalization, the Current TRO
Shareholders shall exchange all of the currently outstanding capital stock of
TRO for newly-issued Non-Voting Common Shares, and the Former TRO Debtholders
shall exchange approximately $6,000,000 of







indebtedness owed by TRO to such parties for newly-issued Preferred Shares;
(iii) TRO shall issue Voting Common Shares authorized as part of such
recapitalization to the PREIT-RUBIN, Inc. Employee Stock Ownership Trust (the
"Employee Stock Ownership Trust"), which shall thereupon own all of the
outstanding Voting Common Shares and hold all such shares pursuant to the
terms of the PREIT-RUBIN, Inc. Employee Stock Ownership Plan (the "Employee
Stock Ownership Plan"); and (iv) the outstanding capital stock of TRO Illinois
shall be transferred to TRO (the "TRO Consolidation").

         As a result of the transactions described in subclauses (i) through
(iii) of the immediately preceding paragraph (collectively, the "TRO Recap"),
immediately prior to the closing of the acquisition of the Preferred Shares
and Non-Voting Common Shares by the Partnership as contemplated herein, all of
the outstanding Preferred Shares shall be owned by the Former TRO Debtholders,
all of the outstanding Voting Common Shares shall be owned by the Employee
Stock Ownership Trust and all of the outstanding Non-Voting Common Shares
shall be owned by the Current TRO Shareholders.

         Immediately prior to or concurrent with the closing of the
acquisition of the Preferred Shares and Non-Voting Common Shares contemplated
herein, PREIT intends to contribute substantially all of its assets to the
Partnership in return for the issuance to PREIT Subsidiary of Class A limited
partner interests in the Partnership ("Class A Units") as contemplated by the
First Amended and Restated Agreement of Limited Partnership of PREIT
Associates, L.P. that is to be executed and delivered at such closing (the
"Amended Partnership Agreement").

         The parties hereto desire to set forth, inter alia, the terms and
conditions by which the Partnership will acquire all of the outstanding
Preferred Shares from the Former TRO Debtholders and all of the outstanding
Non-Voting Common Shares from the Current TRO Shareholders in return for the
issuance of Class A Units.

         The acquisition of the outstanding Preferred Shares and NonVoting
Common Shares contemplated herein is part of a larger transaction in which,
inter alia: (i) the Partnership will acquire from TRO or TRO Affiliates (as
hereinafter defined) all of the right, title and interest of TRO or the TRO
Affiliates in and to The Court at Oxford Valley, Hillview Shopping Center and
Northeast Tower Center (collectively, the "Existing Properties") pursuant to
the terms and conditions of the Contribution Agreement dated as of the date

                                      -2-






Hill Partner, Inc. and Rubin Oxford Valley Associates, L.P. and the
Contribution Agreement dated the date hereof (the "Northeast Contribution
Agreement") among PREIT, the Partnership, Roosevelt Blvd. Co., Inc. and
certain individuals; (ii) the Partnership will acquire all the right, title
and interest of (1) Magnolia Retail Associates, L.L.C. in and to Magnolia
Mall, Florence, South Carolina (the "Magnolia Mall") pursuant to an assignment
by PREIT to the Partnership of all of PREIT's rights and obligations under
that certain Purchase and Sale Agreement dated June 30, 1997 (the "Magnolia

L.L.C., as seller, obtained by an assignment by TRO to PREIT pursuant to an
Agreement Regarding Assignment of Purchase and Sale Agreements dated June 30,
1997 (the "EPD Assignment Agreement") by and between TRO and PREIT; and (2)
Diversified Equity Corporation of Illinois, Inc. in and to North Dartmouth
Mall, Dartmouth, Massachusetts (the "North Dartmouth Mall" and, together with
Magnolia Mall, the "EPD Properties") pursuant to an assignment by TRO to PREIT
to be made, in accordance with the terms of the EPD Assignment Agreement, on
the Closing Date hereunder of all of TRO's rights and obligations under the
Purchase and Sale Agreement dated June 30, 1997 by and between TRO, as buyer,

Date hereunder of all of PREIT's rights and obligations under the North
Dartmouth Agreement to the Partnership; and (iii) the Partnership will acquire
from TRO Predevelopment, LLC, a limited liability company controlled by
certain TRO Affiliates and TRO Shareholders, all of the right, title and
interest of such limited liability company (the "Predevelopment Partnership")
in and to the following predevelopment properties: the Blue Route Metroplex,
Christiana Strip Shopping Center, Red Rose Commons, certain properties in York
and Warrington, Pennsylvania and, under certain circumstances described in the

(collectively, the "Predevelopment Properties") pursuant to the terms and
conditions of the Predevelopment Properties Contribution Agreement dated as of
the date hereof (the "Predevelopment Properties Contribution Agreement") among
PREIT, the Partnership and TRO Predevelopment, LLC.

                      NOW, THEREFORE, in consideration of the premises and
the mutual representations, warranties, covenants and agreements contained
herein, the parties hereto, intending to be legally bound, hereby agree as
follows:


                SECTION 1. ACQUISITION OF PREFERRED SHARES AND
                           NON-VOTING COMMON SHARES

         1.2 Issuance of Class A Units.

                      (a)  In consideration for the sale, transfer,

jurisdiction identified in Section 3.1 of the Disclosure Letter delivered by
the TRO Shareholders to PREIT and the Partnership on the date hereof (the "TRO

such qualification except where the failure to be so qualified would not have
a material adverse effect on the condition (financial or otherwise), assets,
results of operations or business of such Company (a "Material Adverse
Effect").

         3.2 Power and Authority.

valid and binding obligation of each TRO Shareholder enforceable against him
or it in accordance with its terms, except as such enforceability may be
limited by bankruptcy, insolvency, reorganization or similar laws affecting
creditors' rights generally or by general equitable principles. When executed
and delivered as contemplated herein, the other Shareholder Transaction
Documents shall, assuming due authorization, execution and delivery thereof by
the other parties thereto, constitute the legal, valid and binding obligation
of each TRO Shareholder that is a party thereto enforceable against him or it
in accordance with their respective terms, except as such enforceability may
be limited by bankruptcy, insolvency, reorganization or similar laws affecting
creditors' rights generally or by general equitable principles.

                  (b) Each Company has all requisite corporate power and
authority to execute, deliver and perform its obligations under this Agreement
and all other Shareholder Transaction Documents to which such Company is a
party. The execution, delivery and performance by each Company of this
Agreement and the other Shareholder Transaction Documents to which it is a
party have been duly authorized by all necessary corporate action on the part
of such Company. This Agreement has been duly and validly executed and
delivered by each Company and constitutes the legal, valid and binding

equitable principles. When executed and delivered as contemplated herein, each
of the other Shareholder Transaction Documents to which a Company is a party
shall, assuming due authorization, execution and delivery thereof by the other
parties thereto, constitute a legal, valid and binding obligation of such
Company enforceable against it in accordance with its terms, except as such
enforceability may be limited by bankruptcy, insolvency, reorganization or
similar laws affecting creditors' rights generally or by general equitable
principles.

properties or any of either Company's directors, officers, partners or
shareholders in their capacities as such, before or by any court, government

or before an arbitrator of any kind. Except as described in Section 3.7(a) of
the TRO Disclosure Letter, no such pending claim, action, suit, proceeding or
investigation, if determined adversely, would result in a liability that is
not covered by insurance in excess of $25,000 in the case of any single action
or $100,000 in the case of all such actions in the aggregate. To the knowledge
of the TRO Shareholders, except as described in Section 3.7(a) of the TRO
Disclosure Letter, no such claim, action, suit, proceeding or investigation is
presently threatened or contemplated. Except as disclosed in Section 3.7(a) of
the TRO Disclosure Letter, there are no unsatisfied judgments, penalties or

knowledge of the TRO Shareholders, no officer, director, partner, shareholder
or employee of either Company is subject to any Order that prohibits such
officer, director, partner, shareholder or employee from engaging in or
continuing any conduct, activity or practice relating to the Business. The

satisfy obligations to Persons other than TRO that are entitled to a portion
of such fees or are entitled to receive any compensation in respect of
services compensated in whole or in part by such fees, shall equal or exceed
$1.3 million.

                  (c) The Balance Sheet and the Interim TRO Balance Sheet

                  (a) Each Company has either good and valid title to, or has
a valid, subsisting and unchallenged leasehold interest in or right to use,
all assets and properties owned, used or leased by it. Each Company owns all
of the assets and properties (whether tangible or intangible) that are
reflected as owned in its books and records (including, without limitation,
all assets reflected in the interim financial statements referred to in
Section 3.8 other than the assets listed in Section 3.12 of the TRO Disclosure
Letter as being held under capitalized leases), free and clear of all security
interests, liens, claims, pledges, charges, easements, equitable interests,

leased by the Companies are in the possession or under the control of the
Companies and are suitable for the purposes for which they are being used, are
in good condition and repair, ordinary wear and tear excepted, and are of a
condition and nature sufficient for the conduct of the Business as it has been
conducted since January 1, 1997.

                  (b) Upon consummation of the TRO Consolidation contemplated
by Section 5.14, TRO will acquire good and valid title to all of the
outstanding shares of capital stock of TRO Illinois, free and clear of all
Encumbrances (other than applicable securities law restrictions).

                  (a) Section 3.11(a) of the TRO Disclosure Letter sets forth
a true, correct, and complete list of each parcel of real property owned,
leased, occupied or otherwise used by either Company other than real property
in which the Companies have no equity or other interest except their interests
as providers of management, consulting or related services (such real
property, together with all buildings, structures, fixtures and improvements
located thereon or appurtenant thereto, are, collectively, the "Real
Property").

                  (b) Section 3.11(b) of the TRO Disclosure Letter sets forth
a complete list of all real property in which either Company, any TRO
Shareholder or any TRO Affiliate has or has the right to acquire, directly or
indirectly, any equity or other interest (including, without limitation, as a
provider of management, consulting or other related services in respect of
real estate or as a holder of development or other rights with respect to real
estate) other than (i) real property that constitutes a single-family
residence or (ii) in the case of all such Persons other than Ronald Rubin,
George Rubin, Joseph Strauss and their affiliates, real property in which such
Person's only interest is passive ownership. Such list accurately and fully
describes each parcel of such real property and the nature of each such
Person's interest therein. For purposes of this Agreement, "TRO Affiliate"
means: (i) any corporation of which one or more TRO Shareholders owns or
otherwise possesses the power to direct the vote, directly or indirectly, of
an amount of voting securities sufficient to elect a majority of the board of
directors of such corporation and (ii) any other Person controlled by,
controlling, or under common control with one or more TRO Shareholders. For
the purposes of this definition, "control" means the power to direct the
management or policies of a Person, directly or indirectly, whether through
the ownership of voting securities, by contract or otherwise; provided that
any Person of which any one or more TRO Shareholders owns beneficially or of
record, either directly or through one or more intermediaries, more than 35%
of the ownership interests shall be conclusively presumed to be a TRO
Affiliate except that a Person that holds or that will hold title to a
Predevelopment Property or to an Existing Property, that is managed
exclusively by Ken Goldenberg or one of his affiliates and in which Ken
Goldenberg or one of his affiliates owns 50% or more of the outstanding equity
interests shall not constitute a TRO Affiliate hereunder.

(f) assets" as such term is defined in Code section 341(f)(4). Neither Company
has agreed to or is required to make any adjustments under Code section 481(a)
by reason of a change in accounting method or otherwise. The books and records
of each Company are sufficient to prove the correctness of all tax returns for
open tax years and to determine and to prove the adjusted tax basis for
federal income tax purposes of each asset of such Company.

shall bear all costs and expenses arising from the preparation of the Proxy
Statement and the financial statements required to be filed by PREIT with

                                     -45-






the Securities and Exchange Commission, and PREIT shall pay TRO, at the
Closing or promptly following termination of this Agreement, upon submission
to PREIT of reasonably detailed invoices with respect thereto, an amount equal
to the reasonable legal fees (the "Requested Legal Expenses") incurred by TRO
as the result of a written request of PREIT, or its counsel, to assist in the
preparation of the Proxy Statement or the compliance by PREIT with the
Securities and Exchange Commission or American Stock Exchange rules and
regulations; provided that if there is a Closing, such amount shall be
included in the Closing Loan provided for in Section 5.17 hereof and provided
further that if this Agreement is terminated following a breach of this
Agreement by either Company or by any TRO Shareholder, such payment to TRO by
PREIT shall not be required. Notwithstanding the foregoing, if this Agreement
is terminated pursuant to Section 9.2 hereof solely on account of the failure
to fulfill the condition set forth in Section 9.1(f) herein, then PREIT shall
pay up to a maximum of $1,000,000 in the aggregate of all reasonable
Transaction Costs incurred by the Companies and the TRO Shareholders upon
submission to PREIT of reasonably detailed invoices and such other information
related thereto as PREIT may reasonably request. TRO shall pay all of its
Transaction Costs, other than the Transaction Costs to be reimbursed by PREIT
as described above, prior to Closing.

         5.12 Confidentiality. From and after the Closing Date, no TRO
Shareholder shall disclose directly or indirectly to any Person, other than in
the ordinary course of the employ of such TRO Shareholder by PREIT or any
affiliate thereof, without the prior written authorization of PREIT, any
client lists, pricing strategies, client and employee files and records, any
proprietary data or trade secrets of either Company, or any financial or other
information about either Company not in the public domain.

         5.13 Voting Agreements of Sylvan M. Cohen and Leonard I. Korman.
Contemporaneously with the execution and delivery of this Agreement, Sylvan M.
Cohen and Leonard I. Korman shall each deliver to TRO a duly executed voting
agreement in the form attached hereto as Exhibit 5.13.

         5.14 TRO Consolidation. Immediately prior to Closing, the TRO
Shareholders that own shares of capital stock of TRO Illinois will convey all
of such shares, free and clear of all Encumbrances and constituting all of the
outstanding shares of capital stock of TRO Illinois, to TRO.

         5.15 TRO Recap. Prior to Closing, TRO shall take, and the TRO
Shareholders shall cause TRO to take, all actions necessary or appropriate to
effect the TRO Recap. In connection with the consummation of the TRO Recap,
the TRO Shareholders shall, inter alia. (i) cause TRO to amend and restate its
articles of

                                     -46-






incorporation and bylaws in the forms set forth in Exhibit 5.15-A hereto,
thereby changing its corporate name and effecting changes in its capital stock
necessary to effect the TRO Recap and (ii) cause TRO to adopt the Employee
Stock Ownership Trust in the form set forth in Exhibit 5.15-B hereto and to
create the Employee Stock Ownership Trust pursuant to the trust agreement set
forth in Exhibit 5.15-C hereto.

         5.16 Predevelopment Properties; Concord Pike; Girard Estate. After
Closing, no TRO Shareholder or TRO Affiliate shall have any interest in the
development or ownership of any Predevelopment Property, the Girard Estate
project or the Concord Pike property other than as a result of the
participation of TRO, the Partnership or an affiliate thereof and other than
as provided in the Predevelopment Properties Contribution Agreement.

         5.17 Closing Loan; Purchase of Equity Fund.

                  (a) On the date hereof, TRO has delivered to PREIT a
preliminary statement and no later than 5 business days prior to Closing TRO
shall deliver to PREIT a final statement (the "Closing Loan Statement")
setting forth in reasonable detail the nature and amount of: (i) all
reasonable out-of-pocket expenses (other than amounts advanced under the
Goldenberg Letter Agreement that are included in the Equity Fund) theretofore
paid or incurred but not yet paid by TRO, any TRO Shareholder or any TRO
Affiliate to third parties in connection with the acquisition and development
of the EPD Properties and those properties that constitute Predevelopment
Properties as of the Closing, in each case to the extent not theretofore
reimbursed out of proceeds arising from the Predevelopment Properties; (ii)
all reasonable start-up expenses theretofore incurred by TRO with respect to
the management of the EPD portfolio of properties up to a maximum of
$1,500,000; and (iii) the Requested Legal Expenses described in Section 5.11,
in each case together with detailed invoices and other documentation that
PREIT may reasonably request in order to verify the foregoing. At the Closing,
either PREIT or the Partnership shall loan (the "Closing Loan") to TRO an
amount equal to the aggregate amount of the expenses set forth on the Closing
Loan Statement. Promptly following the Closing, TRO shall use the proceeds of
the Closing Loan to retire all indebtedness of TRO to third parties with
respect to the expenses set forth on the Closing Loan Statement.

                  (b) The Closing Loan Statement shall be accompanied by a
statement of the outstanding principal amount of the Equity Fund and the
interest factor thereon then payable in accordance with the terms of the
Goldenberg Letter Agreement. Immediately prior to the Closing, TRO will sell,
assign and transfer to the Partnership all of TRO's right, title and interest
in the Equity Fund, and the Partnership will pay TRO an amount of cash equal
to the amount of the Equity Fund and interest factor. To the extent

                                     -47-






that TRO does not own the entirety of the Equity Fund and the interest factor
on the date hereof, it shall acquire rights thereto from the TRO Shareholders,
together with written representations and warranties in such form and
substance as PREIT shall reasonably request with respect to ownership and
right to assign.

                  (c) At the Closing, the Partnership shall assume all of the
liabilities and obligations of TRO and TRO Shareholders under the Goldenberg
Letter Agreement arising after Closing other than liabilities or obligations
arising from a breach of or default under such agreement prior to Closing.

         5.18 Acquisitions by TRO Affiliates. Prior to Closing, the TRO
Shareholders shall cause the TRO Affiliates not to, without the prior written
consent of PREIT, acquire, directly or indirectly, any ownership or other
interest in any retail or residential real property that is not currently
listed in Section 3.11(b) of the TRO Disclosure Letter and that is of a type
that would have been includable in such list if such interest had been held
prior to the date hereof.

         5.19 Board of Trustees.

                  (a) The Board of Trustees of PREIT (the "Board") shall take
all actions necessary or appropriate to appoint or elect Ronald Rubin, George
Rubin and Rosemarie Greco to be trustees of the Trust as of the Closing so
that, after such appointment or election, the Board of Trustees will consist
of six current members as of the date hereof and the three new members so
elected or appointed. In the event that any of the foregoing is unavailable to
serve as trustees as of the Closing, the Board shall elect or appoint one or
more substitutes therefor designated by TRO, provided, however, that if
Rosemarie Greco is unavailable, TRO shall designate a substitute that is
wholly independent of PREIT, the Companies, the TRO Shareholders and the TRO
Affiliates that is of recognized standing and is otherwise acceptable to the
Board.

                  (b) Immediately following the Closing, the Board shall cause
a special committee of the Board to be formed (the "Special Committee"). The
Special Committee shall consist of three independent trustees of PREIT, one of
whom shall initially be Rosemarie Greco (or her substitute). The
responsibilities of the Special Committee shall be to address and resolve
following Closing matters pertaining to the transactions contemplated herein.
If following Closing the holders of more than 33-1/3% of the then-outstanding
Class A Units issued to TRO Shareholders or TRO Affiliates or any trustee of
PREIT request from time to time that the Special Committee consider (x)
whether the contemplated incurrence by PREIT of non-project specific
indebtedness or the raising by PREIT of equity capital may have an unintended
and

                                     -48-






inequitable effect on PREIT or the holders of the Class A Units or (y) whether
the breach by PREIT of any of its representations and warranties set forth
herein has had any adverse effect upon PREIT's Adjusted FFO, the Special
Committee shall consider such request and may, but shall not be required to,
make any adjustments that the Special Committee deems appropriate in its sole
discretion, including, without limitation, any adjustment to the applicable
Annual Hurdles and Annual Targets (and the TRO Shareholders acknowledge that
the members of the Special Committee shall have no personal liability for
their decisions). If after Closing, there is a final judgment or settlement
with respect to litigation instituted prior to the date hereof by [the
Bermans] and as a result thereof PREIT or one of its affiliates is required to
pay an amount greater than the amount currently reserved therefor on PREIT's
financial statements, PREIT is required to write off revenues that were
recorded on PREIT's financial statements prior to the date hereof or the
percentage interest of PREIT in any property as it is currently accounted for
is reduced, such percentage of such holders shall have the right to cause the
Special Committee to consider the adverse effect of any such event upon the
earn-out set forth in Section 2.2. The Special Committee shall, in respect of
matters described in the immediately preceding sentence, be required to make
appropriate adjustments. In considering the appropriateness of any such
adjustment, the Special Committee shall consider adjustments as may be
appropriate to address any adverse effect on the earn-out specified in Section
2.2.

         5.20 Distributions Prior to Closing; Howell Shopping Center.

                  (a) Notwithstanding anything to the contrary set forth
herein, prior to the Closing Date (and therefore prior to the consummation of
the TRO Recap and TRO Consolidation), TRO may, to the extent lawful, pay a
dividend to its shareholders consisting of: (i) all cash and cash equivalents
owned by TRO, including, without limitation, cash proceeds of the Closing Loan
(but excluding any cash and cash equivalents that are to be used in order to
satisfy the representation and warranty set forth in Section 3.9(b) hereof);
(ii) all accounts receivable other than rent roll receivables, tenant
deposits, funds held on behalf of others, and fully collectible accounts
receivable identified by TRO on a schedule delivered to the Partnership
pursuant to Section 5.29 that are to be retained by TRO in order to satisfy
the representation and warranty set forth in Section 3.9(b) hereof; and (iii)
all assets specifically listed on Schedule 5.20(a) hereto. No account
receivable shall be distributed to shareholders if treatment as a receivable
or the distribution would be a breach of Section 5.26 hereof.

                  (b) Notwithstanding anything to the contrary herein, prior
to the Closing, TRO shall cause all of TRO's right, title and interest in and
to predevelopment rights described on

                                     -49-






Schedule 5.20(b) hereto to be transferred to the Predevelopment Partnership.

                  (c) (i) Unless a contract approved in form and substance by
PREIT (such approval not to be unreasonably withheld) giving Home Depot the
right to purchase Howell Shopping Center is in effect as of Closing, Howell
Shopping Center shall constitute a Predevelopment Property. If such a contract
(the "Howell Purchase Agreement") is in effect as of Closing, Howell Shopping
Center shall not constitute a Predevelopment Property except under the
circumstances described below.

                           (ii)  This subparagraph shall apply only if Howell
Shopping Center is not a Predevelopment Property as of Closing. Prior to the
Closing Date, TRO, the TRO Affiliates and the TRO Shareholders shall assign to
a newly-formed New Jersey limited liability company (the "Howell LLC") all of
their rights to the proceeds of the disposition of their interest in the
Howell Shopping Center. The TRO Shareholders shall cause the Howell LLC to
have no assets or liabilities (other than for payment of current services
rendered by third parties and any debt incurred by Howell LLC to acquire the
property constituting the Howell Shopping Center) except for its rights under
the Howell Purchase Agreement and all beneficial interests in the Howell
Shopping Center held by TRO, the TRO Shareholders or its TRO Affiliates prior
to Closing and the obligation to reimburse the TRO Shareholders and the TRO
Affiliates for the expenses and fees accrued as of the Closing (the expenses
and fees incurred as of the date hereof are set forth on Schedule 5.20(c)),
provided that such obligation shall be payable only out of the proceeds of the
disposition of the Howell Shopping Center that are received by the Howell LLC.
The Partnership and TRO Shareholders shall cause the Howell LLC, following its
receipt of the proceeds of a sale of Howell Shopping Center to Home Depot
pursuant to the Howell Purchase Agreement and the satisfaction of such
obligation and the other permitted liabilities referred to in the preceding
sentence, to distribute the net proceeds to its members. If the Howell
Purchase Agreement expires, terminates or is otherwise abandoned by Howell LLC
or Home Depot at any time, the Partnership shall have the right and option to
have Howell LLC assign all of its right, title and interest in and to Howell
Shopping Center to the Partnership (or its designee) in exchange for the
Partnerships's membership interest in Howell LLC, in which case Howell
Shopping Center shall from and after such date be treated as a Predevelopment
Property under the Predevelopment Properties Contribution Agreement, all
predevelopment costs and expenses with respect thereto will be paid by the
Partnership to Howell LLC which shall use the payment to satisfy the
obligations of Howell LLC and the TRO Shareholders shall cause Howell LLC to
become a party to the Predevelopment Properties Contribution Agreement. If the
Partnership does not exercise its option to take an assignment within 30 days
of written notice from the

                                     -50-






Howell LLC that such option has arisen as aforementioned, the Partnership
shall have no further rights or obligations in respect of the Howell Shopping
Center or the Howell LLC and Howell LLC shall have the right, subject to the
terms of the other agreements referred to herein, to develop, own or dispose
of such property.

         5.21 Employees. No later than 15 days prior to Closing, TRO shall
deliver to PREIT a list of current employees whose employment shall be
terminated by TRO prior to Closing. TRO shall be solely responsible for any
severance pay, accrued salary, pension benefits, unemployment compensation,
vacation pay and any other obligations created or owing as a consequence of
such termination of employment, and the TRO Shareholders shall cause TRO to
take all actions necessary to discharge all of such liabilities and
obligations in full prior to Closing so that as of Closing TRO shall have no
further liabilities or obligations with respect thereto.

         5.22 Employment Agreements. Contemporaneously with the execution and
delivery of this Agreement, TRO has executed and delivered Employment
Agreements with George Rubin, Joseph Coradino, Patricia Berns, Leonard Shore,
Alan Feldman, Doug Grayson and Eric Mallory and PREIT has executed and
delivered Employment Agreements with Ronald Rubin and Edward Glickman, in all
cases to be effective upon Closing. Prior to Closing, TRO and Joseph Straus,
Jr. may enter into an employment agreement satisfactory to PREIT. All
employment and other commission, compensation, equity participation or similar
agreements between any of the foregoing Persons and either Company shall be
terminated as of the Closing and neither Company shall have any further
obligation thereunder (other than to pay accrued and unpaid salary that is
included in the amount described in subclause (iv) of Section 3.9(b) and
accrued and unpaid bonuses that are included in subclause (v) of Section
3.9(b)).

         5.23 PREIT Fiscal Year. After the Closing, PREIT shall take all
action necessary or appropriate to change its fiscal year for financial
reporting purposes to a calendar year basis effective no later than the fourth
calendar quarter of 1997.

         5.24 Contribution of PREIT Assets. PREIT shall take all action that
may be necessary or appropriate, as of the Closing or promptly thereafter, to
effect the contribution of substantially all of PREIT's assets to the
Partnership substantially in accordance with the plan of contribution set
forth in Exhibit 5.24 hereto. In exchange for such contribution, the
Partnership shall issue to PREIT Subsidiary that number of additional Class A
Units that, when aggregated with the numbers of Class A Units issued to PREIT
Subsidiary as of the date hereof, equals the number of outstanding PREIT
Shares as of the Closing.


                                     -51-






         5.25 TRO Board Meetings. After Closing, TRO shall give PREIT advance
written notice of all meetings of its board of directors and PREIT shall be
entitled to designate, from time to time, a representative who shall be
entitled to be present at all of such meetings but who shall not have any vote
in any such proceedings of the TRO board of directors.

         5.26 Receivables. For the period from January 1, 1997 to the Closing
Date, neither Company shall recognize any revenues or related receivables from
management fees, leasing commissions, consulting fees, brokerage fees,
shopping center advertising agency fees and all other items of revenue other
than the Development Fees (which shall be handled in accordance with the last
sentence hereof) and the South Park rent roll receivable paid prior to Closing
unless both of the following conditions are met: (1) the applicable Company
does not have any substantive obligation for future performance relating to
the amounts recognized as revenues or receivables, whether imposed by written
contract or otherwise; and (2) collection of the amount recorded as a
receivable is reasonably assured and if amounts are due more than one-year
from the transaction date, any such amounts recorded shall be discounted to
their net present value using the prime rate of interest in effect at the time
as recorded in The Wall Street Journal. Any amounts received on account of any
item of revenue shall be reflected as a deposit liability on the applicable
Company's balance sheet until both of these conditions are met.
Notwithstanding the foregoing, the development fees listed on Schedule 5.26
hereto (the "Development Fees") shall be recognized as receivables of either
Company for purposes of Sections 3.9 or 5.20 or any other provision of this
Agreement only to the extent such fees remain unpaid as of the Closing, are
scheduled to be paid pursuant to Schedule 5.26 prior to Closing and have been
earned by either Company prior to Closing in accordance with the percentage of
completion method of accounting under GAAP.

         5.27 Life Insurance. If requested by PREIT to do so, Ronald Rubin
will promptly take all action, including undergoing medical examinations,
required in order to secure the issuance of the life insurance policy
contemplated in Section 6.15.

         5.28 Liabilities.

                  (a) The TRO Shareholders and PREIT acknowledge that their
original expectation was that, at Closing, the Companies would be free of all
liabilities and obligations except (x) obligations to perform future services
under Contracts disclosed pursuant to this Agreement; (y) contested claims by
third parties identified pursuant to this Agreement that PREIT agreed to
accept, and (z) ordinary course of business accounts and taxes payable. The
TRO Shareholders have advised PREIT that there are other liabilities and
obligations which may not be fully

                                     -52-






discharged prior to Closing. In order to induce PREIT to enter into this
Agreement and to accept the existence at Closing of certain liabilities and
obligations:

         (i)      Prior to the distribution of the Proxy Statement to the
                  shareholders of PREIT and, in any event, within 24 days
                  from the date hereof, the TRO Shareholders shall cause
                  TRO to be irrevocably and absolutely released by
                  writings reasonably satisfactory in form and substance
                  to PREIT from all guarantees, indemnities, obligations,
                  undertakings or liabilities of any nature whatsoever
                  (other than non-contractual obligations or liabilities
                  which might arise solely from TRO's status as a former
                  general partner in Twelfth Street Hotel Associates,
                  L.P. of which the TRO Shareholders are unaware) in
                  respect of the PSFS Building in Philadelphia,
                  Pennsylvania, including, without limitation,
                  contractual liabilities or obligations (whether
                  absolute, accrued, contingent, liquidated, unliquidated
                  or otherwise) arising by virtue of any interest that
                  TRO may have had, directly or indirectly, in such
                  property and those set forth in Section 5.28(i) of the
                  TRO Disclosure Letter, which the TRO Shareholders
                  represent and warrant are the only such guarantees,
                  indemnities, obligations, undertakings or liabilities
                  in connection with the PSFS Building that affect either
                  Company;

         (ii)     Prior to the distribution of the Proxy Statement to the
                  shareholders of PREIT and, in any event, within 24 days
                  from the date hereof, the TRO Shareholders shall cause
                  each beneficiary of the guarantee by TRO identified in
                  Section 5.28(ii) of the TRO Disclosure Letter to have
                  irrevocably and absolutely released TRO from all
                  obligations and liabilities in respect thereto by a
                  writing reasonably satisfactory in form and substance
                  to PREIT;

        (iii)     The TRO Shareholders shall cause the Companies as of Closing
                  to be free and clear of all liabilities and obligations of any
                  nature (whether absolute, accrued, contingent, liquidated,
                  unliquidated or otherwise) that (A) are due and payable or
                  performable at or prior to Closing and that are not otherwise
                  expressly identified and dealt with pursuant to this Section
                  5.28, including, without limitation, those liabilities and
                  obligations set forth in Section 5.28(iii) of the TRO
                  Disclosure Letter, and (B) that are due or payable or
                  performable at or after the Closing and that are not otherwise
                  expressly identified and dealt with pursuant to this Section
                  5.28;


                                     -53-






         (iv)     All Damages arising out of claims identified in Section
                  5.28(iv) of the TRO Disclosure Letter shall, to the
                  extent not satisfied in full prior to Closing, be
                  subject to indemnification pursuant to Section 10.1(b)
                  hereof by Ronald Rubin and George Rubin (who, for
                  purposes of this Section 5.28 and Section 10 hereof,
                  shall include all entities controlled by either or both
                  thereof which receive Class A Units issued on the
                  Closing Date);

         (v)      The TRO Shareholders shall cause the representations and
                  warranties set forth in Section 3.9(b) with respect to the
                  liabilities and obligations referred to in subclauses (i),
                  (iii), (iv), (v) and (vi) of the first sentence of Section
                  3.9(b) to be true and correct as of Closing; and

         (vi)     Ronald Rubin and George Rubin shall indemnify and hold
                  harmless PREIT and the Partnership pursuant to Section
                  10.1(b) against any Damages arising from any of the
                  liabilities or obligations listed in Section 5.28(vi) of the
                  TRO Disclosure Letter.

                  (b) At Closing, Ronald Rubin and George Rubin (and the
entities referred to in (iv) above) shall execute and deliver a pledge
agreement in form and substance reasonably satisfactory to PREIT by which they
shall pledge to the Partnership (in order to secure their indemnification
undertakings in Section 10.1(b) and 10.1(c)) such number of Class A Units
issued to them hereunder and under the Court at Oxford Valley Contribution
Agreement on the Closing Date as shall be equal in value to 150% of the
maximum amount of all liabilities and obligations referred to in subclauses
(i), (ii), (iii) and (vi) above (except as otherwise specifically provided
under Section 5.28(vi) of the TRO Disclosure Letter) which have not been fully
released or paid prior to Closing as security for their indemnities hereunder
with respect to such obligations and liabilities pursuant to Section 10.1(b)
and 10.1(c) hereof. For this purpose, each Class A Unit shall be deemed to
have a value of $_____. The requirement for a pledge to cover potential
Damages resulting from non-compliance with subclauses (i), (ii) and (iii) if
Closing occurs shall not affect any condition to Closing in favor of PREIT
with respect to such covenants or the obligations under 10.1(b) or 10.1(c) for
breaches of the covenants set forth in this Section 5.28.

         5.29 Accounts Receivable. (a) The TRO Shareholders shall deliver to
PREIT at least 5 business days prior to Closing a schedule identifying any
accounts receivable that are to be retained by TRO in order for the TRO
Shareholders to satisfy their representations and warranties set forth in
Section 3.9(b). TRO shall provide PREIT with all information and documentation

                                     -54-






reasonably requested by PREIT in order for PREIT to confirm the nature and
status of such accounts receivable.

                  (b) The TRO Shareholders acknowledge that if any account
receivable is used to cover an amount referred to in subclause (I) through
(IX) of Section 3.9(b) and such account receivable is not paid as of the
earlier of (i) 90 days after it is due and payable or (ii) one year following
Closing, such account receivable shall be deemed not to have constituted a
"fully collectible" account receivable, and the TRO Shareholders shall be
responsible under Section 10.1(b) to pay TRO the amount of such account
receivable promptly after such date. Upon payment therefor by the TRO
Shareholders, TRO shall assign its right, title and interest in and to any
such account receivable to the Person designated by Ronald Rubin.


            SECTION 6. CERTAIN CONDITIONS PRECEDENT TO PREIT'S AND
                        THE PARTNERSHIP'S OBLIGATIONS.

         The obligation of PREIT and the Partnership to consummate the
acquisition of the Contributed TRO Shares and to take the other actions
required to be taken by them at the Closing is subject to the fulfillment by
or at the Closing of each of the following conditions, any or all of which may
be waived by PREIT in its sole discretion:

         6.1 Representations and Warranties. Each of the representations and
warranties of the TRO Shareholders set forth in this Agreement that is
qualified by materiality shall be true and correct, and each of the
representations and warranties of the TRO Shareholders set forth in this
Agreement that is not so qualified shall be true and correct in all material

                  (b) by mutual consent of PREIT and TRO;

                  (c) by TRO and the TRO Shareholders, on the one hand, or

Shareholders' Meeting or at any adjournment or postponement thereof; or

                  (g) by PREIT, if: (i) the Board shall have determined in
good faith that the consummation of the transactions contemplated herein would

any significant portion of the assets or equity securities of a third party,
or (C) a purchase by a third party of all or any significant portion of the

faith that the Alternative Transaction is reasonably likely to be consummated;
and (iii) after consultation with its financial advisors, the Board shall have
determined in good faith that the Alternative Transaction would be more

         9.2 Procedure for Termination; Effect of Termination.

9.1 shall give written notice thereof to each other party hereto, whereupon
this Agreement shall terminate and the transactions contemplated hereby shall
be abandoned without further action by any party and all further obligations
of the parties under this Agreement will terminate; provided, however, that if
such termination is pursuant to Section 9.1(c), the terminating party's right
to pursue all legal remedies (including damages and/or specific performance)
contemplated by Section 10 will survive such termination unimpaired except as
limited by Section 9.2(b) and provided further that if such termination is
pursuant to Section 9.1(g), PREIT shall promptly thereafter pay TRO the sum of
$2 million and provided further that if such termination is pursuant to
Section 9.1(f), the obligations of the parties pursuant to Section 5.11 shall
survive termination.

                  (b) Following a termination pursuant to Section 9.1(c), each
TRO Shareholder other than Ronald Rubin and George Rubin shall have no
liability for breaches of covenants, agreements, obligations, representations
or warranties set forth herein except to the extent that such TRO Shareholder
(i) breached a covenant, agreement or obligation set forth herein the
performance of which was within his power to control, (ii) made an intentional
misrepresentation or (iii) is the only TRO

                                     -63-

Following a termination pursuant to Section 9.1(c), neither Ronald Rubin,
George Rubin, the Companies, PREIT nor the Partnership shall have any
liability for breaches of covenants, agreements or obligations set forth
herein to the extent that such breaches arise from the actions of, or failure
to act by, Persons other than the parties hereto and the TRO Affiliates and
notwithstanding such party's best efforts to cause such Person to act in a
manner that would result in the satisfaction of such party's covenants,
agreements and obligations hereunder.


                         SECTION 10. INDEMNIFICATION.

         10.1 Indemnification by TRO Shareholders. Subject to the limitations
set forth in Section 10.3, each TRO Shareholder shall indemnify, defend and
hold harmless PREIT, the Partnership and TRO (collectively, "Buyer Indemnified
Persons") against and in respect of any and all losses, costs, expenses
(including, without limitation, costs of investigation and reasonable defense
and attorneys' fees), claims, damages, obligations, liabilities or diminutions
in value, whether or not involving a third party claim (collectively,
"Damages"), arising out of, based upon or otherwise in respect of: (a) any
inaccuracy in or breach of any representation or warranty of such TRO
Shareholder made in or pursuant to this Agreement (including, without
limitation, the certificate referred to in Section 8.2(a)(ii) which, for this
purpose, will be deemed to have stated, inter alia, that the TRO Shareholders'
representations and warranties in this Agreement were true and correct as of
the Closing Date as if made on the Closing Date); (b) any breach or
nonfulfillment of any covenant or obligation of any TRO Shareholder contained
in this Agreement; or (c) any of the matters described in Schedule 10.1
hereto.

         10.2 Indemnification by PREIT. PREIT shall indemnify, defend and hold
harmless the TRO Shareholders against and in respect of any and all Damages
arising out of, based upon or otherwise in respect of: (a) any inaccuracy in
or breach of any representation or warranty of PREIT made in or pursuant to
this Agreement (including, without limitation, the certificate referred to in
Section 8.2(b)(v) which, for this purpose, will be deemed to have stated,
inter alia, that PREIT's representations and warranties in this Agreement were
true and correct as of the Closing Date as if made on the Closing Date); or
(b) any breach or nonfulfillment of any covenant or obligation of PREIT or the
Partnership contained in this Agreement.

         10.3 Limitations on Liability.

                  (a) No TRO Shareholder shall have any obligation to
indemnify any Buyer Indemnified Person against Damages pursuant to Section
10.1(a) of this Agreement arising out of or

                                     -64-






based upon any inaccuracy in or breach of any representation or warranty
(other than those set forth in Section 3.6) made in or pursuant to this
Agreement unless and until the aggregate of all such Damages suffered or
incurred by Buyer Indemnified Persons exceeds $350,000; in which event the
Buyer Indemnified Persons shall be entitled to indemnification for the full
amount of all Damages suffered or incurred; provided, however, that the above
limitation shall not be applicable to any claim for Damages pursuant to
Sections 10.1(b) (other than an indemnity claim based upon a breach of Section
5.28(a)(iii)(B), which shall be subject to such limitation to the same extent
as a claim for breach of Section 3.9 as described below) or 10.1(c) or based
upon a breach of any representation or warranty made in or pursuant to (x)
Sections 3.1, 3.2, 3.3, 3.4, 3.10(b), 3.28 or 3.31 or (y) Section 3.9, in the
case of a breach of any of the representations and warranties set forth in
Section 3.9 other than due to the existence of liabilities of a nature not
required to be reflected in financial statements prepared in accordance with
GAAP of which the TRO Shareholders had no knowledge prior to Closing.

                      (b) No TRO Shareholder shall have any obligation
to indemnify any Buyer Indemnified Person against Damages based upon any
inaccuracy in or breach of any representation or warranty set forth in Section
3.6 unless and until the aggregate of all such Damages suffered or incurred by
Buyer Indemnified Persons exceeds $50,000; in which event the Buyer
Indemnified Persons shall be entitled to indemnification for the full amount
of all such Damages suffered or incurred.

                      (c)  Following Closing, (i) the TRO Shareholders
shall not be obligated to indemnify Buyer Indemnified Persons against Damages
pursuant to Section 10.1 to the extent that such indemnification payment
(other than indemnification payments in respect of fraud or intentional
misrepresentation), when aggregated with all prior indemnification payments
(other than indemnification payments in respect of fraud or intentional
misrepresentation) by or on behalf of the TRO Shareholders to Buyer
Indemnified Persons or reasonably paid by or on behalf of the TRO Shareholders
to third parties for the benefit of Buyer Indemnified Persons pursuant to this
Agreement, would exceed the Aggregate Value (as hereafter defined), and (ii)
each TRO Shareholder other than Ronald Rubin and George Rubin shall not be
obligated to indemnify Buyer Indemnified Persons against Damages pursuant to
Section 10.1 to the extent that such indemnification payment, when aggregated
with all prior indemnification payments by or on behalf of such TRO
Shareholder to Buyer Indemnified Persons or reasonably paid by or on behalf of
such TRO Shareholder to third parties for the benefit of Buyer Indemnified
Persons pursuant to this Agreement, would exceed the Proportionate Aggregate
Value (as defined below) attributable to such TRO Shareholder, provided that
the limitation of this subclause (ii) shall not apply to the extent an
indemnity claim

                                     -65-






is brought with respect to a breach of a representation and warranty made
solely by such TRO Shareholder and not by such TRO Shareholder and other TRO
Shareholders or with respect to a matter involving fraud or intentional
misrepresentation by such TRO Shareholder. The "Aggregate Value" means an
amount equal to the value of all Class A Units theretofore issued pursuant to
Sections 1.2 and 2.2 (it being acknowledged that for this purpose units that
would have been issued but for an exercise of the set-off rights specified in
Section 10.7 shall be deemed to have been issued), such value to be calculated
by multiplying the number of units times the per share Value (as defined in
the Amended Partnership Agreement) of a PREIT Share as of the date of issuance
of such units.

                  (d) Following Closing, the liability of each TRO Shareholder
other than Ronald Rubin and George Rubin for each indemnity claim pursuant to
Section 10.1 shall be limited to that fraction of the aggregate Damages
incurred by Buyer Indemnified Persons with respect to such claim that is equal
to the quotient whose numerator equals the portion of the Aggregate Value
attributable to units theretofore issued to such TRO Shareholder (for this
purpose units that would have been issued but for an exercise of the set-off
rights specified in Section 10.7 shall be deemed to have been issued) (the
"Proportionate Aggregate Value") and the denominator of which equals the
Aggregate Value; provided, however, that the foregoing shall not limit the
liability of Ronald Rubin or George Rubin, each of whom shall be jointly and
severally liable for 100% of the aggregate Damages incurred (subject to the
cap on aggregate Damages set forth above in subclause (i) of Section 10.3(c)),
and provided further that the foregoing limitation shall not apply to the
extent that an indemnity claim is brought with respect to a breach of a
representation and warranty made solely by such TRO Shareholder and not by
such TRO Shareholder and other TRO Shareholders or with respect to a matter
involving fraud or intentional misrepresentation by such TRO Shareholder.

                  (e) No claim arising out of or based upon any inaccuracy in
or breach of any representation or warranty made in or pursuant to this
Agreement shall be made unless a claim arises and written notice is delivered
to the indemnifying party within the Basic Claims Period (as defined below);
provided that any such claim arising out of or based upon any inaccuracy in or
breach of any representation or warranty made in or pursuant to (x) Sections
3.16, 3.17 or 3.20 may be made at any time before the expiration of the latest
to expire statute of limitations period applicable to an action brought by the
appropriate taxing or other regulatory agency with respect to the matters
forming the basis for such claim and (y) Sections 3.4, 3.25 or 3.28 may be
made at any time. For purposes hereof, "Basic Claims Period" means the period
beginning on the date hereof and ending on the

                                     -66-






date five months after the fiscal year end for first full fiscal year of PREIT
after Closing.

                  (f) Disclosures made after the date hereof and any knowledge
that is acquired about the accuracy or inaccuracy of or compliance with any
representation, warranty, covenant or obligation set forth herein shall not in
any manner affect rights to indemnification hereunder based on any such
representation, warranty, covenant or obligation or be deemed in any manner to
amend the TRO Disclosure Letter. The waiver by PREIT of any condition based on
the accuracy of any representation or warranty, or compliance with any
covenant or obligation, will not affect any right to indemnification based on
such representations, warranties, covenants and obligations unless otherwise
expressly agreed in writing by PREIT. To the extent that any claim for
indemnification may be made under Section 10.1(a) and Section 10.1(c), then
such claim shall be deemed for all purposes to have arisen only under Section
10.1(c) and not under Section 10.1(a).

                  (g) Each party's rights under this Section 10 shall be its
sole remedy against the other parties in respect of any matters arising under
this Agreement, subject to a party's rights, if any, to seek and obtain
specific performance with respect to covenants, agreements and obligations set
forth herein.

                  (h) No party may assert a claim for indemnification pursuant
to Section 10.1 unless the Closing has occurred or this Agreement has been
terminated pursuant to Section 9.

                  (i) The limitations of this Section 10.3 shall not be
applicable in respect of Damages arising from or relating to any breach of
representations or warranties with respect to the Equity Fund.

         10.4 Procedure For Indemnification - Third Party Claims.

                  (a) Within thirty days after receipt by an indemnified party
of notice of the commencement of any proceeding against it to which the
indemnification in this Section 10 *relates, such indemnified party shall, if
a claim is to be made against an indemnifying party under Section 10, give
notice to the indemnifying party of the commencement of such proceeding, but
the failure to so notify the indemnifying party will not relieve the
indemnifying party of any liability that it may have to any indemnified party,
except to the extent that the indemnifying party demonstrates that the defense
of such proceeding is materially prejudiced by the indemnified party's failure
to give such notice.


                                     -67-






                  (b) If any proceeding referred to in paragraph (a) above is
brought against an indemnified party and it gives notice to the indemnifying
party of the commencement of such proceeding, the indemnifying party will be
entitled to participate in such proceeding and, to the extent that it wishes
(unless (i) the indemnifying party is also a party to such proceeding and the
indemnified party determines in good faith that joint representation would be
inappropriate, or (ii) the indemnifying party fails to provide reasonable
assurance to the indemnified party of its financial capacity to defend such
proceeding and provide indemnification with respect to such proceeding), to
assume the defense of such proceeding with counsel reasonably satisfactory to
the indemnified party and, after notice from the indemnifying party to the
indemnified party of its election to assume the defense of such proceeding,
the indemnifying party will not, as long as it diligently conducts such
defense, be liable to the indemnified party under Section 11 for any fees of
other counsel or any other expenses with respect to the defense of such
proceeding, in each case subsequently incurred by the indemnified party in
connection with the defense of such proceeding, other than reasonable costs of
investigation. If the indemnifying party assumes the defense of a proceeding,
(A) it will be conclusively established for purposes of this Agreement that
the claims made in that proceeding are within the scope of and subject to
indemnification; (B) no compromise or settlement of such claims may be
effected by the indemnifying party without the indemnified party's consent
unless (1) there is no finding or admission of any violation of Law by the
indemnified party (or any affiliate thereof) or any violation of the rights of
any Person and no effect on any other claims that may be made against the
indemnified party, and (2) the sole relief provided is monetary damages that
are paid in full by the indemnifying party. The indemnified party will have no
liability with respect to any compromise or settlement of the claims
underlying such proceeding effected without its consent. If notice is given to
an indemnifying party of the commencement of any proceeding and the
indemnifying party does not, within ten days after the indemnified party's
notice is given, give notice to the indemnified party of its election to
assume the defense of such proceeding, the indemnifying party will be bound by
any determination made in such proceeding or any compromise or settlement
effected by the indemnified party.

                  (c) Notwithstanding the foregoing, if an indemnified party
determines in good faith that there is a reasonable probability that a
proceeding may adversely affect it or its affiliates other than as a result of
monetary damages for which it would be entitled to indemnification under this
Agreement, the indemnified party may, with respect to those issues, by notice
to the indemnifying party, assume the exclusive right to defend, compromise,
or settle such proceeding, but the indemnifying party will not be bound by any
determination of a

                                     -68-






proceeding so defended or any compromise or settlement effected without its
consent.

         10.5 Procedure for Indemnification - Other Claims. A claim for any
matter not involving a third party claim may be asserted by notice to the
party from whom indemnification is sought.

         10.6 Acknowledgement. Each TRO Shareholder hereby acknowledges that
the representations, warranties and covenants made by him herein are made in
his capacity as a shareholder of TRO and not as director, officer or employee
of either Company; accordingly, each TRO Shareholder acknowledges and confirms
that following the Closing he shall not have any claim for indemnification by
TRO, the Partnership, PREIT or any affiliate thereof as an officer, trustee,
director or employee thereof in respect of any Damages due or owing by such
TRO Shareholder pursuant to the terms of this Agreement.

         10.7 Right of Set-Off. PREIT and the Partnership shall have the right
to set-off, against any Class A Units which may be owed by PREIT or the
Partnership to any TRO Shareholder, any amount owed by such TRO Shareholder to
any Buyer Indemnified Person pursuant to this Section 10. To the extent that a
TRO Shareholder contests an indemnification claim of PREIT or the Partnership
that would be the basis for the exercise of a right to set off against any
Class A Units owed to such TRO Shareholder, the Partnership shall issue such
Class A Units and deposit them with an escrow agent reasonably satisfactory to
such TRO Shareholder until the earlier to occur of (i) resolution of such
dispute by a final nonappealable order of a court of competent jurisdiction or
(ii) the mutual agreement of such TRO Shareholder and PREIT that such units
should be released from escrow.

         10.8 Indemnification Payments. The TRO Shareholders shall be entitled
to use cash or Class A Units to make indemnification payments hereunder. In
the event Class A Units are used, each such unit shall be valued based on the
per share Value (as defined in the Amended Partnership Agreement) of a PREIT
Share as of the date such unit is tendered to PREIT as an indemnification
payment hereunder.

         10.9 Transfer of Units. Ronald Rubin and George Rubin shall not, and
each shall cause their affiliates not to, transfer any Class A Units issued
pursuant to this Agreement to any of them (or any interest therein) for one
year following such issuance unless the transferee executes and delivers to
PREIT prior to such transfer an agreement, in form and substance reasonably
satisfactory to PREIT, by which such transferee shall agree that all such
transferred units (and proceeds thereof)

                                     -69-






shall be subject to and available to pay the indemnification undertakings of
the TRO Shareholders pursuant to Section 10.1.

                           SECTION 11. MISCELLANEOUS.

         11.1 Survival of Representations and Warranties.

                  (a) The representations and warranties made by the parties
in this Agreement and in the certificates, documents and other agreements
delivered pursuant hereto shall survive the Closing. Anything in this
Agreement to the contrary notwithstanding: (i) the representations and
warranties of the TRO Shareholders hereunder, and the right of the Buyer
Indemnified Persons to indemnification for breach thereof, shall not be
affected by any investigation of the Companies, any TRO Shareholder or any TRO
Affiliate made by PREIT or its agents or representatives and (ii) the
representations and warranties of PREIT hereunder, and the right of the TRO
Shareholders to indemnification for breach thereof, shall not be affected by
any investigation of PREIT or the Partnership or its affiliates made by TRO or
its agents or representatives.

                  (b) In the event of any inconsistency between the statements
made in the body of this Agreement and those contained in the TRO Disclosure
Letter (other than an express exception to a specifically identified
statement), those in this Agreement shall control.

         11.2 Further Assurances. Each party hereto shall use best efforts to
comply with all requirements imposed hereby on such party and to cause the
transactions contemplated hereby to be consummated as contemplated hereby and
shall, from time to time and without further consideration, either before or
after the Closing, execute such further instruments and take such other
actions as any other party hereto shall reasonably request in order to fulfill
its obligations under this Agreement and to effectuate the purposes of this
Agreement and the transactions contemplated herein. Each party shall promptly
notify the other parties of any event or circumstance known to such party that
could prevent or delay the consummation of the transactions contemplated
hereby or which would indicate a breach or non-compliance with any of the
terms, conditions, representations, warranties or agreements of any of the
parties to this Agreement.

         11.3 Notices. All notices or other communications permitted or
required under this Agreement shall be in writing and shall be sufficiently
given if and when hand delivered to the persons set forth below or if sent by
documented overnight delivery service or registered or certified mail, postage
prepaid, return receipt requested, or by telegram, telex or telecopy, receipt
acknowledged, addressed as set forth below or to such other person or persons

         11.4 Assignment and Benefit.

                  (a) The parties hereto shall not assign this Agreement or
any rights hereunder, or delegate any obligations hereunder, without prior
written consent of the other party. Subject to the foregoing, this Agreement
and the rights and obligations set forth herein shall inure to the benefit of,
and be binding upon, the parties hereto, and each of their respective
successors, heirs and assigns.

                  (b) This Agreement shall not be construed as giving any
person, other than the parties hereto and their permitted successors, heirs
and assigns, any legal or equitable right, remedy or claim under or in respect
of this Agreement or any of the provisions herein contained, this Agreement
and all provisions and conditions hereof being intended to be, and being, for
the sole and exclusive benefit of such parties, and permitted successors,
heirs and assigns and for the benefit of no other person or entity.

         11.5 Amendment, Modification and Waiver. The parties may amend or
modify this Agreement in any respect, and PREIT and TRO may: (a) extend the
time for the performance of any of the obligations of the other, (b) waive any
inaccuracies in representations and warranties by the other, (c) waive
compliance by the other with any of the obligations contained in this
Agreement, or (d) waive the fulfillment of any condition precedent to the
performance under this Agreement of the waiving party; provided, however, that
after the approval of the transactions contemplated by this Agreement by the
shareholders of PREIT, there shall be no material amendment or modification of
this Agreement unless the Board of Trustees of PREIT concludes that such
amendment or modification is in the best interests of the PREIT shareholders.
Any such amendment, or modification, extension or waiver shall be in writing.
The waiver by a party of any breach of any provision of this Agreement shall
not constitute or operate as a waiver of any other breach of such provision or
of any other provision hereof, nor shall any failure to enforce any provision
hereof operate as a waiver of such provision or of any other provision hereof.

         11.6 Governing Law; Consent to Jurisdiction. This Agreement is made
pursuant to, and shall be construed and enforced in accordance with, the laws
of the Commonwealth of Pennsylvania (and United States federal law, to the
extent applicable), irrespective of the principal place of business, residence
or domicile of the parties hereto, and without giving effect to otherwise
applicable principles of conflicts of law. Any legal action, suit or
proceeding arising out of or relating to this Agreement may be instituted in
any federal court or in any state court in the Commonwealth of Pennsylvania,
and each party waives any objection which such party may now or hereafter

                                     -72-






have to the laying of the venue of any such action, suit or proceeding, and
irrevocably submits to the jurisdiction of any such court. Any and all service
of process and any other notice in any such action, suit or proceeding shall
be effective against any party if given as provided herein. Nothing herein
contained shall be deemed to affect the right of any party to serve process in
any other manner permitted by law or to commence legal proceedings or
otherwise proceed against any other party in any jurisdiction other than
Pennsylvania. Nothing contained herein or in any Transaction Document shall
prevent or delay PREIT or the Partnership from seeking, in any court of
competent jurisdiction, specific performance or other equitable remedies in
the event of any breach or intended breach by any TRO Shareholder or either
Company of any of its or his obligations hereunder.

         11.7 Section Headings and Defined Terms. The section headings
contained herein are for reference purposes only and shall not in any way
affect the meaning and interpretation of this Agreement. The terms defined
herein and in any agreement executed in connection herewith include the plural
as well as the singular and the singular as well as the plural, and the use of
masculine pronouns shall include the feminine and neuter. Except as otherwise
indicated, all agreements defined herein refer to the same as from time to
time amended or supplemented or the terms thereof waived or modified in
accordance herewith and therewith.

         11.8 Severability. The invalidity or unenforceability of any
particular provision, or part of any provision, of this Agreement shall not
affect the other provisions or parts hereof, and this Agreement shall be
construed in all respects as if such invalid or unenforceable provisions or
parts were omitted.

         11.9 Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original; and any person may
become a party hereto by executing a counterpart hereof, but all of such
counterparts together shall be deemed to be one and the same instrument. It
shall not be necessary in making proof of this Agreement or any counterpart
hereof to produce or account for any of the other counterparts.

         11.10 Entire Agreement. This Agreement, together with the TRO
Disclosure Letter and the agreements, exhibits, and certificates referred to
herein or delivered pursuant hereto, constitute the entire agreement between
the parties hereto with respect to the subject matter hereof and supersede all
prior agreements and understandings, including without limitation, the Letter
Agreement (other than Section IV thereof).

         11.11 Guaranty of Performance by TRO Predevelopment, LLC. Ronald
Rubin and George Rubin hereby guarantee that TRO Predevelopment, LLC will
perform its indemnification obligations

                                     -73-
