                  connection with the ownership, operation and maintenance of
                  the Property and other property related to the Property.

         2.        CONSIDERATION.

         (a) The aggregate consideration (the "Consideration") payable by OP
for 100% of the Interests shall be the difference between $21,150,000 and the
principal amount on the Closing Date of the Existing Loan, subject to
adjustments at Closing pursuant to Section 16 and the reductions described in
Paragraph (e) of Section 3 and Paragraph (c) of Section 18. The Consideration,
as so adjusted, is referred to herein as the "Adjusted Consideration."

         (b) On the Closing Date, each of the Partners who has accepted the
Offer shall, pursuant to the Joinder Agreement and Assignment, assign his, her
or its Interests to OP in exchange for the Exchange Price. "Exchange Price"
for an Interest means the portion of the Adjusted Consideration allocable to
such Interest, as set forth on Schedule 1. At Closing, the General Partners
shall establish from Partnership funds otherwise distributable to the Partners
on or before the Closing Date a "Reserve Amount". "Reserve Amount" means the
sum of: (a) an amount equal to the current liabilities of the Partnership on
the Closing Date (other than the principal amount of the Existing Loan) which
would be accrued on a balance sheet of the Partnership as at the Closing Date
prepared in accordance with generally accepted accounting principles, together
with such other amounts as the General Partners may reasonably require (the
"Liabilities Reserve") and (b) $200,000 (the "Indemnity Reserve"). The Reserve
Amount shall be held and disbursed by the Disbursing Agent (as defined in
Paragraph (c) of this Section 2) as described in Paragraph (c) of this Section
2 and in Paragraphs (a) and (b) of Section 3. The Reserve Amount shall
initially be used to pay (xx) all amounts to satisfy the current liabilities
of the Partnership and other liabilities of the Partnership other than the
Transferred Liabilities ("Liabilities Claims") and (yy) any amounts paid or
subject to claims of OP by reason of a material breach or material
misrepresentation of any representations, warranties, covenants or agreements
of the Partnership which survive Closing (but only during the period of such
survival) ("Indemnity Claims"). In the event that any Partner shall not have
executed and delivered a Joinder Agreement and Assignment on or before the
Closing Date, OP shall have the right to terminate this Agreement on the
Closing Date and receive a return of the Earnest Money Deposit and no party
hereto shall thereafter have any liability hereunder.

         (c) At Closing, the General Partners shall deliver in immediately
available funds from moneys otherwise distributable to the Partners (but not
from proceeds of Consideration) to Holt, Ney, Zatcoff & Wasserman, LLP (the
"Disbursing Agent") the Reserve Amount. The Reserve Amount shall be held and
disbursed pursuant to the terms of an escrow agreement that shall be in form
and substance substantially similar to that attached hereto as Exhibit H.


                                      5



         (d) Partners who have elected to receive cash in exchange for all or
any portion of their Partnership Interests shall be paid so much of the
Exchange Price as they have elected to receive in cash at the Closing.

         (e) Partners who are accredited under applicable securities laws and
who have elected to receive OP Units at least seven days prior to the Closing
Date in exchange for all or any portion of their Partnership Interests shall
be paid so much of the Exchange Price as they have elected to receive in OP
Units by the issuance of OP Units. The number of OP Units to be issued to each
Unit Partner shall be that portion of the Exchange Price as the such Unit
Partner has elected to receive in OP Units divided by the twenty (20) day
trailing average of the closing price of PREIT Common Shares on the New York
Stock Exchange for the twenty (20) business days preceding the third business
day prior to the Closing Date.

         3.       RELEASE OF RESERVES; CLOSING COSTS.

         (a) Rules Applicable to Reserve Amount While Held by the Disbursing
Agent.

         (i) If any claim (a "Claim") is made by OP for payment out of the
Reserve Amount held by the Disbursing Agent of an Indemnity Claim or a
Liability Claim, OP shall thereafter notify the General Partners and the
Disbursing Agent of such Claim. At such time as there is a Final Determination
(as hereinafter defined) with respect to any such Claim, OP and the General
Partners shall jointly instruct the Disbursing Agent to make disbursements out
of the Reserve Amount appropriate to reflect such Final Determination. A
"Final Determination" with respect to a Claim shall occur when: (x) OP and the
General Partners agree in writing to a payment from the Reserve Amount with
respect to a Claim; or (y) the arbitrator determining the disposition of a
Claim pursuant to Section (iv) below renders a final decision with respect to
a Claim determining that a payment is to be made from the Reserve Amount to
OP; or (z) provided that the General Partners (on behalf of all of the former
Partners of the Partnership) shall have been given an opportunity to
participate in the defense of such third-party claim throughout the course of
such third-party claim, the Claim is made on account of a judgment rendered by
a court of competent jurisdiction requiring, on a third-party's claim, a
specified payment on account of such Claim to the third-party claimant and
such judgment has become final and not subject to further appeal.

         (ii) On December 31, 1998, and thereafter, at any time and from time
to time, within 10 days after the written request of the General Partners, OP
shall send a notice (the "Anniversary Notice") to the Disbursing Agent and to
the General Partners describing each then outstanding Claim with respect to
which a Final Determination has not theretofore been made and specifying what
OP believes, acting reasonably and in good faith, to be the aggregate amount
of damages that have been incurred theretofore or are likely to be incurred
thereafter as a result of or arising out of each such Claim (the "Damage
Amount").

                                      6



         (iii) If the General Partners and OP do not agree, the determination
of the Damage Amount with respect to any disputed Claim shall be immediately
submitted to prompt and binding arbitration before an arbitrator appointed by
the Philadelphia, Pennsylvania, office of the American Arbitration Association
in accordance with its rules, and acting in accordance with its rules. If any
such Disputed Amount relates to a third-party claim that is then in litigation
or is otherwise unresolved, the standard to be applied by the arbitrator in
determining the Damage Amount shall be the aggregate amount of damages that
have been or are likely thereafter to be incurred by OP, including OP'
attorneys' fees, court costs and other costs of defense, arising out of such
claim. The award of the arbitrator shall be communicated to the parties and
the Disbursing Agent and shall constitute a Final Determination, which shall
be final, binding and not subject to appeal, with respect to all the Claims
that are the subject of such award, notwithstanding that an underlying
third-party claim still remains unresolved or is subsequently resolved in a
manner inconsistent with the arbitrator's award.

         (b)      Rules Applicable to Amounts Disbursed to the General Partners.

         (i) On December 31, 1998, the Disbursing Agent shall disburse to the
General Partners that portion of the Reserve Amount that has not been paid,
disbursed or is then subject to a pending and unresolved Liability or
Indemnity Claim. The General Partners may then elect (i) to continue to hold
such disbursed amounts in trust for the benefit of the Partners, as a fund
against which to pay unanticipated claims (the "Contingency Reserve"), and/or
(ii) to distribute some or all of such amounts to the Partners in accordance
with their interests.

         (ii) At any time, and from time to time, after December 31, 1998,
that there is a Final Determination that any remaining portion, if any, of the
Reserve Amount is no longer subject to Liability or Indemnity Claims, OP and
the General Partners shall jointly instruct the Disbursing Agent to distribute
such remaining portion to the General Partners. The General Partners may then
elect (i) to continue to hold such disbursed amounts in trust for the benefit
of the Holders, as a fund against which to pay unanticipated claims (the
"Contingency Reserve"), and/or (ii) to distribute some or all of such amounts
to the Holders in accordance with their interests. Notwithstanding the above,
Dissenting Partners shall not be entitled to a distribution of any portion of
the Indemnity Reserve.

         (iii) Subject to the following sentence, not later than January 15,
1999 (provided that there have been no unanticipated Claims asserted against
the Partnership), the General Partners shall distribute any balance remaining
in the Contingency Reserve to the Partners in accordance with their interests.
In the event that on January 15, 1999 there are unanticipated claims pending
or asserted, or the General Partners have reason to believe that such
unanticipated claims may be asserted, the General Partners may continue to
hold the Contingency Reserve until such time as the General Partners deem
prudent, after which any undisbursed amount remaining in the Contingency
Reserve shall be disbursed by the General Partners to the Holders in
accordance with their interests. In no event shall OP or PREIT have any
liability to any Partner in respect of any portion of the Reserve Amount or
the Contingency Reserve.


                                      7

 



        (c) No Claim shall be valid unless a claim is made on or before
December 31, 1998 (or, with respect to any Claim of which notice has been
provided to the General Partners on or before December 31, 1998, such later
date as may be approved by the General Partners).

         (d) OP shall pay all recording fees, its attorneys' fees, the costs
of obtaining a binder or commitment from a title insurance company, the
premium for its title insurance policy, the costs for updating any surveys,
the costs of any environmental surveys and studies, all (if any) Pennsylvania
state and local recordation and/or transfer taxes, the fee described in
section 20 payable to CB Richard Ellis and all other costs and expenses
incidental to or in connection with closing this transaction customarily paid
for by the purchaser of similar property. The Partnership shall pay its
attorneys' fees and all other costs and expenses incidental to or in
connection with closing this transaction customarily paid for by the seller of
similar property, including any costs required to clear title to the Property
in accordance with Section 13 hereof.

         (e) The Consideration shall be reduced by the amount of the fee
described in section 20 payable to CB Richard Ellis and one-half of any
transfer taxes imposed on this transaction, if any.

         (f) On, or at any time prior to, the Closing Date, the General
Partners shall have the right to spend on behalf of the Partnership and/or
distribute to the partners of the Partnership any and all cash and securities
held by the Partnership (other than amounts in its Security Deposit accounts,
unless otherwise provided pursuant to Subsection 16(d)), it being specifically
agreed and understood that OP is not purchasing the cash and securities of the
Partnership, and that a portion of the amounts so distributed shall be applied
to fund the Reserve Amount.

         (g) Promptly following the Closing, (i) the Reserve Amount shall be
adjusted to reflect inaccuracies (if any) in the determination made at the
Closing of the current liabilities of the Partnership on the Closing Date, and
(ii) a payment shall be made to reflect inaccuracies (if any) in the
determination made at Closing of the Partnership's cash and securities.

         4.       OP UNITS.

         (a) Distributions with respect to the OP Units shall be paid pursuant
to the provisions of the Partnership Agreement.

         (b) The OP Units will be redeemable in accordance with the provisions
of the Operating Partnership Agreement.

         (c) The OP Units will be transferable in accordance with the
provisions of the Operating Partnership Agreement.

                                      8



         (d) Upon the terms and conditions of a Registration Rights Agreement,
in the form of Exhibit C attached hereto, to be dated the Closing Date, the
Unit Partners shall have registration rights with regard to any of PREIT
Common Shares which may be issued upon redemption of the OP Units (the
"Registration Rights"). The exercise of Registration Rights shall be without
cost to the Partners.

         5. EXISTING LOAN. To the extent that there are any prepayment or
assumption fees (including any lender approval fees and fees and expenses of
the lender's lawyers and TPA fees and charges) in connection with the Existing
Loan or substituting OP as the general partner with respect to the Existing
Loan, OP shall be responsible for payment of those fees. OP and the
Partnership acknowledge and agree that it is most likely that either the
Existing Loan or a new mortgage ("New Mortgage") will need to be in place in
order to protect the tax deferred nature of the transaction for the Unit
Partners.

         6. PERMITTED EXCEPTIONS. The Property at Closing shall be subject
only to the following (the "PERMITTED EXCEPTIONS"):

         (a)      the Existing Loan;

         (f)      such other agreements and matters as may be agreed to by
                  the General Partners and OP.

         7.1 OBLIGATIONS AND COVENANTS OF OP AND PREIT. OP and PREIT covenant
and agree with the Partnership, both before and after Closing:

         (a) Distributions with respect to the OP Units will be at least equal
in amount and identical in timing to the dividends on PREIT Common Shares,
except that the initial distribution payable with respect to the OP Units
issued to the Unit Partners shall be made on the date on which PREIT shall pay
the dividend to holders of PREIT Common Shares that relates to the earnings
for the calendar quarter in which the OP Units were issued to the Unit
Partners, and shall be prorated such that the Unit Partners will receive a
pro-rata distribution for the period from the date on which the OP Units were
issued to the Unit Partners to, and including, the last day of the calendar
quarter in which the OP Units were so issued.

                                      12



         (b) The General Partners may retain copies of any and all books and
records pertaining to the Partnership and the operation of the Property so
that the General Partners may wind up the affairs of the previously conducted
business.

         (c) At the Closing, OP shall deliver to each Unit Partner good and
marketable title to the OP Units allocated to such Unit Partner, free and
clear of all liens, charges, encumbrances and restrictions, except as
contained in the Operating Partnership Agreement, the Registration Rights
Agreement, and the Lock-Up Agreement, and shall, by execution of the
Amendment, admit each Unit Partner as a limited partner in OP.

         (d) At all times during the Tax Protection Period (as defined in the
following sentence), OP shall (and following the Tax Protection Period OP
shall use reasonable efforts to) allocate to each Unit Partner, for Federal
income tax purposes, (i) pursuant to Section 752 of the Code, nonrecourse debt
of OP in an aggregate amount not less than the Basis Protection Amount
(calculated as provided in subsection (e)) of such Partner, as adjusted from
time to time, and (ii) sufficient qualified nonrecourse financing (within the
meaning of Section 465 of the Code) to prevent the application of Subsection
465(e) of the Code to such Partner. For purposes of this Agreement, the "Tax
Protection Period" means the period commencing on the Closing Date and
continuing thereafter for eight years.

         (e) The initial Basis Protection Amount of each Unit Partner shall be
equal to the amount of such Unit Partners capital account deficit in the
Partnership as at (just prior to) the contribution of such Partner's Interest
in the Partnership to OP on the Closing Date (and without taking into account
the book-up adjustment to be made thereto in connection with such
contribution). For the Tax Protection Period, the Basis Protection Amount of
each Unit Partner shall be adjusted annually to reflect changes occasioned at
the level of OP, including, without limitation, distributions made by OP, to
the extent (and only to the extent) that such changes produce changes in the
tax basis of such Unit Partner for his interest in OP. OP agrees that the
methodology chosen under Section 704(c) of the Code in connection with the
Unit Partners' contributions of their Interests to OP hereunder shall be the
"traditional" method.

         (f) For the Tax Protection Period, OP shall not sell, exchange,
transfer or otherwise dispose of the Property, or any replacement of the
Property (in any event, a "Property Transfer"), unless such Property Transfer
occurs in such manner as to be tax free to each Unit Partner or unless OP
reimburses each Unit Partner on an after-tax basis for any tax liability
resulting from such Property Transfer by reason of Section 704(c) of the Code.
Following the Tax Protection Period, OP shall use reasonable efforts to
utilize Section 1031 of the Code to prevent or minimize recognition of taxable
gain by the Unit Partners in connection with each disposition of the Property
or any replacement thereof.

                                      13



         (g) OP and PREIT shall cause the Existing Loan to be paid as and when
the same becomes payable.

         (h) OP and PREIT shall take such action from time to time as may be
necessary to assure that, after the Closing, no Unit Partner has an obligation
to make a contribution to OP, except (i) to the extent expressly agreed upon
by such Unit Partner or (ii) as provided by applicable law or the Operating
Partnership Agreement.

         (i) OP and PREIT shall take such action from time to time as may be
necessary to prevent any power of attorney granted by a Unit Partner pursuant
to the Operating Partnership Agreement from being employed to produce an
effect which, if produced by an amendment to the Operating Partnership
Agreement, would cause such amendment to be ineffective unless adopted with
the consent of such Partner.

         7.2 CONSENTS AND SPECIAL AGREEMENTS OF THE PARTNERS. By execution of
a Joinder Agreement and Assignment in the form of Exhibit B hereto, each
Partner:

         (a) Irrevocably consents to each of the transactions contemplated
hereby, including, without limitation (i) the transfer of all of the
Interests, including the Interests of the General Partner, to OP and/or its
permitted assigns; (ii) the admission and substitution of OP and its permitted
assigns as substitute general or limited partners of the Partnership and the
sole partners of the Partnership on and after the Closing Date; and (iii) the
termination of the Partnership under the Code by reason of the foregoing.

         (b) Consents to an amendment to the Agreement of Limited Partnership
of the Partnership, effective on the date of this Agreement, deleting the
first two sentences of Section 6.4 thereof.

         (c) If a Unit Partner, irrevocably consents to an amendment to the
Operating Partnership Agreement establishing a sixty (60) day redemption
period for OP Units issued on or after August 1, 1998 (including, without
limitation, the OP Units to be issued pursuant to the terms hereof).
      
         8. REPRESENTATIONS AND WARRANTIES OF THE PARTNERSHIP.

         (a) The Partnership and each Accepting Partner hereby, jointly and
severally, represents and warrants that each of the following numbered
sentences is true, complete and accurate as of the date of this Agreement and,
subject to any qualifications made on the Closing Date necessary to make such
representations and warranties continue to be true and correct on the Closing
Date by reason of changes in such matters covered thereby between the date

sentences. The truth, completeness and accuracy of the following numbered
sentences (aside from omissions and inaccuracies which are not material or not
adverse to the interests of the Partnership or OP), and without regard to the
Closing Date Qualifications, as of the Closing Date shall be a condition
precedent to OP's obligation to effect the Closing, but if OP proceeds to
effect the Closing only the following numbered sentences, subject to the
Closing Date Qualification, shall survive the Closing. For purposes of the
following numbered sentences, the Partnership will be considered to have
knowledge of a fact if and only if that fact is actually known to Michael I.

                  thereunder; and no event has occurred that, with the giving
                  of notice, or the passage of time, or both, would constitute

                  outstanding Interests and the percentage interest in

                  the event that any Partner listed on Schedule 1 transfers
                  any Interests prior to the Closing Date, the Partnership
                  shall use good faith reasonable efforts to promptly provide

                  include the names of the transferor and the transferee, the

                  Interests owned by such Partner and owns such Interests free
                  and clear of all liens, claims, charges or encumbrances;

                  assignee of any portion of the Interests which OP is
                  entitled to acquire hereunder, shall own all of the
                  Interests in the Partnership, free and clear of all liens,
                  charges and encumbrances except those arising by reason of
                  actions taken by OP or its assignee.

                  the Partnership; and (iii) as otherwise disclosed in this
                  Agreement, the Partnership has no material liability or

                  or to become due, absolute, contingent or otherwise,
                  including liabilities for taxes (or any interest or
                  penalties thereto).

         (39)     Except as previously disclosed to OP, all of the ranges and
                  refrigerators in the Property are the property of the
                  Partnership and not of the tenants.

                                      19

                  state, county, local or foreign government, or subdivision
                  or agency thereof with respect to the assets or the business
                  of the Partnership, and including any interest, penalties or
                  additions attributable thereto.

         (41)     At least 90% of the Interests in the Partnership are owned

Partners set forth in this Agreement, subject to the Closing Date
Qualifications, including, without limitation, the following indemnity, shall

from and against any and all losses, costs, claims, liabilities, damages and
expenses, including, without limitation, reasonable attorneys' fees, arising
as the result of a material breach of any of the representations and
warranties of the Partnership and Partners set forth in this Agreement which

this Agreement, neither the General Partners nor any other Partner shall have
any personal liability, and no action of any kind shall be commenced or
maintained against any of them or their respective assets, with respect to
this Agreement and/or the transactions described in this Agreement, and OP,
its successors and assigns, shall look solely to (i) prior to the Closing
Date, the assets of the Partnership and (ii) from and after the Closing Date,

representations or warranties of any kind, whether as to merchantability, or
fitness for a particular purpose, or otherwise.

                  result in any breach of, any contract, agreement, law, rule
                  or regulation to which either PREIT or OP is a party, or by
                  which either PREIT or OP is bound.

                  delivered, and constitutes a legal and binding obligation of
                  OP and PREIT, enforceable in accordance with its terms,
                  except as such enforcement may be limited by bankruptcy and
                  other laws affecting creditors rights generally.

         (4)      Each instrument to be executed and delivered by OP and/or
                  PREIT pursuant to this Agreement, or in connection herewith,
                  will, when executed and delivered, be valid and enforceable
                  against OP and/or PREIT in accordance with its terms, except
                  as such enforcement may be limited by bankruptcy and other
                  laws affecting creditors' rights generally and principles of
                  equity applicable to the availability of the remedy of
                  specific performance.

         (5)      To the best knowledge of OP, there is no litigation,
                  proceeding or investigation pending, or threatened, against
                  or affecting OP, or PREIT, that might affect the validity of
                  this Agreement, or any action taken, or to be taken, by OP,
                  or PREIT, pursuant to this Agreement, or that might have a
                  material adverse effect on the business of OP.

         (6)      At the Closing, OP shall deliver to each Unit Partner good
                  and marketable title to the OP Units allocated to such Unit
                  Partner, free and clear of all liens, charges, encumbrances

                  Commission, are true and correct in all material respects

                  liquidation, dissolution or recomposition of PREIT or OP, or
                  the debts of PREIT or OP, under any law relating to

                  debtors, or seeking the appointment of a receiver, trustee,
                  custodian or other similar official for PREIT or OP.

                  consents to the transfers hereunder of their Interests by
                  all of the Partners shall have been obtained.

         (8)      The Partnership possesses as of the date hereof and shall

                  letters executed by the General Partners in the form of
                  Exhibit G hereto; that will, in OP's reasonable opinion,

                  and without undue expense, financial statements for the
                  Property that will comply with Rule 3-14 of Regulation S-X

Partnership and the Partners under this Agreement shall be subject to the
satisfaction of the conditions set forth following (the "Partnership's
Conditions"):

                                      24



         (1)      All of the representations and warranties of OP and PREIT
                  set forth in this Agreement shall be true, accurate and
                  correct as of the Closing Date (as if made on the Closing
                  Date).

         (2)      OP shall have delivered to the Partnership all of the
                  documents and other items required to be delivered by OP
                  under the terms of this Agreement.

         (3)      The fulfillment by OP of such other conditions to Closing as
                  are set forth in this Agreement.

         (b) Each of the Partnership's Conditions is for the benefit of the
Partnership, and, accordingly, any such condition may be waived by the
Partnership at any time.

         (c) If any of the Partnership's Conditions shall not have been
fulfilled by OP or otherwise satisfied on or before the dates specified above
or if no date is specified by the Closing Date, or waived by the Partnership,
the Partnership shall have the right to terminate this Agreement by written
notice to OP, in which event this Agreement shall, thereafter, be deemed to be
null, void and of no further force or effect, and neither party shall have any
further rights or obligations under this Agreement, but subject to the
provisions of Section 23 of this Agreement.

         11A. CONDITION TO ALL PARTIES' OBLIGATIONS.

         (a) The obligations of all of the parties under this Agreement shall
be subject to the satisfaction of the condition set forth following (the
"Mutual Condition"):

         (1)      The Existing Lender shall have approved the transfer of the
                  Existing Loan (and/or substitution of OP as general partner
                  of the Partnership) or OP shall have received a commitment
                  for substitute financing which can be closed within 45 days
                  after the execution of this Contribution Agreement.

         (b) If the Mutual Condition shall not have been fulfilled or
otherwise satisfied or waived by both parties, either party shall have the
right to terminate this Agreement by written notice to the other party, in
which event the Earnest Money Deposit shall be returned to OP and this
Agreement shall, thereafter, be deemed null, void and of no further force or
effect, and neither party shall have any further rights or obligations under
this Agreement, but subject to the provisions of Section 23 of this Agreement.


                                      25



         12. INSPECTION PERIOD. Subject to the rights of existing tenants at
the Property, OP shall have a period to and including the day following the
date of execution hereof (the "Due Diligence Period") within which to cause
one or more surveyors, attorneys, engineers, auditors, architects, and/or
other experts of its choice (i) to inspect any document related to any
Property, including, without limitation, all Leases and related documents,
documents pertaining to the Existing Loan, working drawings, plans and
specifications, surveys, appraisals, engineer's reports, environmental
reports, insurance policies, service contracts, real estate tax receipts and
annual and monthly operating statements, and (ii) to inspect, examine, survey,
appraise and obtain engineering inspection and environmental reports with
respect to the Property, documents pertaining to the Existing Loan, or all of
the Property, and otherwise to do all that, which, in the opinion of PREIT, is
necessary to determine the condition and value of the Property for the uses
intended by OP, provided, however, that OP shall not conduct any environmental
study beyond a Phase 1 level without the consent of the Partnership, which
consent shall not be unreasonably withheld. OP may declare the Due Diligence
Period ended at any earlier time. OP must be satisfied in all respects (in the
sole and absolute discretion of OP) with the results of all reviews,
inspections and investigations conducted by, or under, OP during the Due
Diligence Period. If OP shall not be so satisfied, OP may, within the Due
Diligence Period, terminate this Agreement, in which event OP shall have no
obligation or liability under this Agreement, or with regard to the
Partnership or the Property, and OP shall be entitled to the immediate return
of the Earnest Money Deposit, and this Agreement shall, thereafter, be null,
void and of no further force or effect, all, however, subject to Section 23.
If not so terminated by OP, this Agreement shall continue in full force and
effect according to its terms, and OP shall be considered to have waived any
and all unsatisfactory conditions as a result of which OP could have
terminated this Agreement pursuant to this Section 12, but this Agreement
shall remain subject to all other conditions to OP's obligation to complete
closing as set forth herein. OP shall be responsible for payment of all of the
costs of its due diligence activities, including, without limitation, all
engineering and environmental reports, and all financial and Lease audits. OP
and PREIT shall indemnify and hold the Partnership and the Partners harmless
from and against any and all loss, claims, damage and expense arising out of
entry by OP and its agents onto the Property and any testing performed
thereon; OP and PREIT shall repair any damage which it may cause as a result
of any such entry and testing; OP and PREIT shall cause their entry,
inspections and testing (if any) to be conducted in a manner so as to minimize
disruption to tenants at the Property. The indemnity and repair obligations of
OP and PREIT are collectively referred to herein as the "Inspection
Indemnity."

         OP and PREIT shall give written notice to the Partnership as soon as
the Board has, pursuant to paragraphs (a)(3) and (a)(4) of Section 9 hereof,
acted upon a request for approval of this Agreement and the transactions
envisioned herein. In the event that the Board has failed to approve, or OP
shall fail to give the Partnership notice of approval, within the Due
Diligence Period, the Partnership shall have the right to terminate this
Agreement by giving written notice to OP, in which event the Earnest Money
Deposit shall be returned to OP and neither party shall have any further
obligation under this Agreement, subject to Section 23.

         13.      TITLE.

         (a) At Closing, the Partnership will hold insurable fee simple title
to the Property, free and clear of all liens, charges and encumbrances, except
the Permitted Exceptions.

                                      26



         (b) Within 5 days of the execution of this Contribution Agreement,
the Partnership will furnish and deliver to OP a copy of the most recent title
policy issued with respect to the Property and a copy of the most recent
survey of the Property.

         (c) The obligation of OP to complete the transaction described in
this Agreement is conditioned upon the ability of OP to obtain title insurance
with respect to the Property insuring that, as of the Closing Date, title to
the Property is not subject to any liens, encumbrances or other than the
Permitted Exceptions.

         (d) The Partnership agrees that, upon the request of OP, it will
provide an affidavit in such customary form as shall allow OP to obtain a
non-imputation endorsement to the title policy purchased by OP.

         (e) If any title commitment, UCC search or survey discloses
exceptions to title other than the Permitted Exceptions, or any other matter
which does not conform to the requirements of this Agreement, OP shall so
notify the Partnership in writing, such notice to be furnished to the
Partnership, if at all, within fifteen (15) days following receipt by OP of
the title commitments, the UCC searches and surveys, but not later than the
last day of the Inspection Period. The Partnership shall have the right, but
not the obligation, within fifteen (15) days from the date of the receipt of
such notice by the Partnership (the "Correction Period"), to have each such
unpermitted exception to title removed, or to correct each such other matter,
in each case to the reasonable satisfaction of OP. OP shall have no obligation
to close within the Correction Period unless the Partnership shall have caused
each unpermitted exception to be removed or corrected to the reasonable
satisfaction of OP. If, within the Correction Period, the Partnership fails to
have each such unpermitted exception removed, or to correct each such other
matter as aforesaid, OP may, at its option, and as the sole and exclusive
remedy of OP, either (i) terminate this Agreement, in which event this
Agreement, without further action of the parties, shall become null and void
such that neither party shall have any further rights or obligations under
this Agreement (subject to Section 23), and OP shall be entitled to the
immediate return of the Earnest Money Deposit and any fees or costs incurred
by OP in reviewing the state of title to the Property or obtaining a survey of
the Property, or (ii) elect to take title to each Property as it then is. If
OP fails to make either such election within five (5) days following the
expiration of the Correction Period, OP shall be deemed to have elected option
(ii). Any exception to title (other than a Permitted Exception), or any other
matter which does not conform to the requirements of this Agreement, to which
the OP does not object, as aforesaid (and for this purpose if OP elects (or is
deemed to elect) option (ii) all such exceptions and other matters shall be
considered exceptions and other matters to which OP does not object), shall be
deemed approved by OP, and shall be deemed to be an additional Permitted
Exception. Notwithstanding anything to the contrary contained herein, the
Partnership shall be obligated to remove (or to cause the title company to
affirmatively insure over) at the expense of the Partnership (a) any mortgages
or deeds to secure debt regarding any financing obtained by any Partnership,
other than the Existing Loan; (b) any mechanic's or materialman's lien for
work done on any Property on behalf of the Partnership; and (c) any other
judgments or liens encumbering the Property.

                                      27


         14.      CLOSING DATE.

Partnership, pursuant to their respective rights to do so set forth elsewhere
herein, and within the time(s) herein limited, the closing of the transaction
contemplated by this Agreement (the "Closing") shall occur on the second
business day following the first business day on which all of the conditions
to Closing set forth in Sections 10, 11 and 11A have been satisfied or waived
in writing by the party or parties having a right to do so. OP and PREIT agree
to use commercially reasonable good faith efforts to expeditiously attempt to
obtain all necessary approvals of the Existing Lender. The Closing shall be
held at OP's office, or at such other place, and at such time, as may be
mutually agreed upon by the parties.

         (b) If the Closing shall not have occurred and this Agreement shall
not otherwise have been terminated pursuant to a right to do so set forth
herein by September 30, 1998, then at any time thereafter (and before the
Closing or other termination of this Agreement) either party not in default of
its covenants and agreements hereunder may terminate this Agreement upon at
least five (5) days' notice to the other party, whereupon no party shall have
any further rights or duties hereunder except as provided in Section 23(c).
For purposes of the preceding sentence, OP and PREIT shall collectively be
considered a single party.

         (5)      charges for water, sewer, electricity, fuel, gas, telephone
                  and other utilities, which are not metered or otherwise
                  charged directly to tenants under the Leases; provided that
                  if the consumption of any such utilities is measured by
                  meters, at Closing the Partnership shall furnish a current
                  reading of each meter, and provided, further, that if there
                  is not a meter, or if the meter(s) cannot be read by the
                  relevant utility prior to the Closing, the charges therefor
                  shall be adjusted at the Closing on the basis of the charges
                  for the prior period for which bills were issued, and shall
                  be further adjusted when the bills for the period including
                  the Closing Date are issued;

                  which is or may become payable with respect to the Property
                  in annual installments; such other amounts as are
                  customarily adjusted between parties to similar transactions
                  in the local jurisdiction.

                                      31




         (b) Rents which are due and payable to the Partnership by any tenant
but uncollected as of the Closing Date shall not be adjusted at the Closing.
All rents collected by the Partnership after the Closing Date shall be applied
(i) first to any due but unpaid rentals accruing subsequent to the Closing
Date, then (ii) to any rents past due for the calendar month in which the
Closing Date occurs (subject to adjustment), and (iii) then to any rents due
and unpaid prior to the Closing Date (other than those described in clause
(i)). All rent collected after Closing for any period prior to the Closing
shall belong to the former Partners of the Partnership, and if paid to OP or
the Partnership, OP shall promptly send such rent to the General Partners for
distribution to the former Partners of the Partnership pursuant to the
agreement described in subparagraph (a)(6) of Section 10, less all reasonable
expenses incurred by OP or the Partnership, if any, in regard to the
collection thereof. At the Closing, the Partnership shall deliver to OP a
schedule of all such past due, but uncollected rents owed by tenants. All
rents collected by the Partnership prior to Closing, for rental period(s)
subsequent to the Closing shall be paid by the Partnership (and not
distributed pursuant to Subsection 3(f) of this Agreement) to OP at the
Closing or deducted as an adjustment at Closing. All rents collected by OP or
the Partnership for rental periods after the Closing shall belong to the
Partnership, and if paid to the former Partners of the Partnership, the former
Partners of the Partnership shall promptly send such rent to the Partnership.

         (c) Any adjustment estimated at the Closing shall be finally adjusted
as soon as practicable after the Closing. Any error in the calculation of
apportionments shall be corrected subsequent to the Closing with appropriate
credits to be given based upon corrected adjustments; provided, however, that
all adjustments (except as to errors caused by misrepresentation) shall be
deemed final on December 31, 1998.

         (d) At the option of either party, immediately prior to Closing the
Partnership shall be entitled to distribute to its Partners all amounts held
in its Security Deposit accounts, in which event there shall be an adjustment
at Closing of an amount equal to the aggregate amount of the Security Deposits
(with interest, if required to be paid on such deposits) shown on the updated
Rent Roll provided by the Partnership.

         (e) The Partners shall be responsible for, and shall make
arrangements for payment of, all amounts due to the Closing Date for
employees, salaries, accrued vacation pay, withholding and payroll taxes, and
other benefits, and any management fee affecting the Property (the General
Partners may utilize one or more payroll periods after Closing to finalize
these payments); the Partnership shall be responsible for all such expenses
commencing upon the Closing Date.

         (f) The General Partners and OP shall agree upon the amount of the
current liabilities of the Partnership (other than the Existing Loan) which is
to be included in the Liabilities Reserve.

         17.      POSSESSION. Upon completion of the Closing, the Partnership
shall retain full and complete possession of the Property, subject only to the
Permitted Exceptions and such other agreements and matters as may be agreed to
by the General Partners and OP.

         18.      CONDEMNATION AND DESTRUCTION.

         (a) If, prior to the Closing Date, the Property, or any part of any
building included in the Property, is taken by eminent domain (or is the
subject of a pending or contemplated taking which has not been consummated),
the Partnership shall notify OP of such fact, and OP shall have the option
(which option shall be set forth in a notice from OP to the Partnership given
not later than fifteen (15) business days after receipt of the notice from the
Partnership):


                                      32




         (i)      to terminate this Agreement, in which event, the Earnest
                  Money Deposit shall be returned to OP, and, thereafter, this
                  Agreement shall be deemed to be null, void and of no further
                  force or effect between the parties, subject to Section 23;
                  or

         (ii)     to accept the Interests of the Accepting Partners, without
                  abatement of the Consideration, in which event the
                  Partnership shall be entitled to receive and keep all
                  amounts awarded or to be awarded to the Partnership as the
                  result of the taking (and, without limiting the generality
                  of the foregoing, Subsection 3(f) shall not apply to such
                  amounts).

A failure by OP to make a timely election pursuant to the preceding sentence
shall be considered an election pursuant to clause (ii) thereof.

         (b) If, prior to the Closing Date, all or any material part of any
Property is damaged or destroyed by fire or other casualty, the Partnership
shall notify OP of such fact, and OP shall have the option (which option shall
be set forth in a notice from OP to the Partnership given not later than
fifteen (15) business days after receipt of the notice from the Partnership):

         (i)      to terminate this Agreement, in which event, the Earnest
                  Money Deposit shall be returned to OP, and, thereafter, this
                  Agreement shall be deemed to be null, void and of no further
                  force or effect between the parties, subject to Section 23;
                  or

         (ii)     to accept the Interests of the Accepting Partners, in which
                  event the Partnership shall be entitled to receive and keep
                  the insurance proceeds awarded or to be awarded to the
                  Partnership as the result of such damage or destruction
                  (and, without limiting the generality of the foregoing,
                  Subsection 3(f) shall not apply to such proceeds), and the
                  Consideration shall be reduced by the amount of any
                  deductible under the applicable insurance policies of the
                  Partnership.

A failure by OP to make a timely election pursuant to the preceding sentence
shall be considered an election pursuant to clause (ii) thereof.

         (c) In the event there is damage to or destruction of an immaterial
part of the Property by fire or other casualty, such damage or destruction
shall, subject to receipt of insurance proceeds, be repaired promptly by the
Partnership, and in the event such damage or destruction cannot be fully
repaired by the Closing Date, then the Closing shall be held as scheduled, and
OP shall accept the Interests of the Accepting Partners without abatement of
the Consideration, in which event the Partnership shall be entitled to receive
and keep the insurance proceeds awarded or to be awarded to the Partnership as
the result of such damage or destruction (and, without limiting the generality
of the foregoing, Subsection 3(f) shall not apply to such proceeds), and the
Consideration shall be reduced by the amount of any deductible under the
applicable insurance policies of the Partnership.

                                      33



         (d) An "Immaterial" part of the Property shall be deemed to have been
damaged or destroyed if the cost of repair or replacement thereof shall be
$250,000, or less, and a "Material" part thereof shall be deemed to have been
damaged or destroyed if the cost of repair or replacement thereof shall be
greater than $250,000.

         19.      [INTENTIONALLY OMITTED]

         20. BROKER'S COMMISSION. The Partnership and OP each represent to the
other than the transaction described in this Agreement was not brought about
or assisted in any way by any broker, firm or salesman, or other person or
persons acting or functioning as, or in a role similar to a broker (any such
broker, firm or salesman, or other person, is herein referred to as a
"Broker"), except CB Richard Ellis, to whom OP shall pay a real estate
brokerage commission in the amount of $373,190 at the time of, and in
conjunction with the Closing of the transaction under this Agreement. The
amount of the brokerage commission paid by OP shall be a reduction of the
Consideration as provided in paragraph (e) of Section 3. OP and the
Partnership each agrees to indemnify the other from and against any claim and
expenses, including legal fees, if any other fees or commission is determined
to be due by reason of the employment of any other broker by the indemnifying
party, this indemnity and representation shall survive Closing.

         21. EARNEST MONEY. Concurrently with the execution of this Agreement
by both OP and the Partnership, OP will deposit $250,000 by check (the
"Earnest Money Deposit") with the Disbursing Agent. The Earnest Money Deposit
shall be held pursuant to the terms of an Escrow Agreement in the form of
Exhibit F attached hereto and disbursed as provided in Section 23. As used
anywhere in this Agreement, the term "Earnest Money Deposit" includes all
earnings thereon, if any.

         22. COOPERATION. At all times during the term and pendency of this
Agreement, the Partnership will cooperate fully with OP in all reasonable
manner in providing books, records and other documentation for review,
including, without limitation, all Leases and related documents, copies of
documentation relating to the Existing Loan, working drawings, plans and
specifications, surveys, appraisals, engineer's reports, environmental
reports, insurance policies, service contracts, real estate tax receipts,
copies of tax returns filed by the Partnership, and annual and monthly
operating statements relating to the Property, and in the possession of, or
reasonably available to the Partnership. Subject to existing tenant leases,
the Partnership will provide access to the Property for all physical
inspections required by OP. The Partnership will provide access by the
representatives of OP to all financial and other information relating to the
Property in the possession of or reasonably available to the Partnership as is
sufficient to enable such representatives to prepare audited financial
statements, at the expense of OP, in conformity with Regulation S-X of the
Securities and Exchange Commission (the "Commission"), and any registration
statement, report or disclosure statement required to be filed with the
Commission. OP shall conduct itself and its examinations in a manner to
minimize disruption to the staff and tenants of the Partnership and Property.


                                      34



         23. DEFAULTS AND REMEDIES.

         (a) If the Partnership fails or refuses to perform in accordance with
the terms of this Agreement, including, without limitation, the failure or
refusal to perform any covenant or obligation to be performed by the
Partnership prior to the Closing, or if any of the representations and
warranties of the Partnership contained in this Agreement, shall not be true,
complete and correct at Closing (aside from inaccuracies and omissions which
are not material or not adverse to the interests of the Partnership or OP), OP
may, as its exclusive remedies, seek to specifically enforce any covenant or
obligation which the Partnership fails or refuses to perform or terminate this
Agreement, in which event (or if this Agreement is terminated by either party
pursuant to Subsection 14(b)) the Earnest Money Deposit shall be returned to
OP at which time this Agreement shall be deemed to be null, void and of no
further force or effect between the parties (subject to subsection (c)).

         (b) If OP or PREIT fails or refuses to perform in accordance with the
terms of this Agreement, including, without limitation, the failure or refusal
to perform any covenant or obligation to be performed by OP or PREIT prior to
the Closing, or if any of the representations and warranties of OP or PREIT
contained in this Agreement shall not be true, complete and correct at
Closing, the Partnership may terminate this Agreement, in which event, the
Earnest Money Deposit shall be paid to the Partnership as liquidated damages
(which shall be the sole and exclusive remedy of the Partnership against OP or
PREIT), at which time this Agreement shall be deemed to be null, void and of
no further force or effect between the parties (subject to subsection (c)). In
that regard, the Partnership acknowledges and agrees that (i) the Earnest
Money Deposit is a reasonable estimate of, and bears a reasonable relationship
to, the damages suffered and costs incurred by the Partnership as a result of
having subjected the Interests to the terms of this Agreement; (ii) the actual
damages suffered and costs incurred by the Partnership as a result of such
failure of OP to close under this Agreement would be extremely difficult and
impractical to determine; (iii) OP seeks to limit its liability under this
Agreement to the amount of the Earnest Money Deposit in the event this
Agreement is terminated and the transaction contemplated by this Agreement
does not close due to a default of OP under this Agreement; and (iv) the
Earnest Money Deposit shall be and constitute valid liquidated damages. The
foregoing limitation shall apply only in the event that OP does not close the
transaction contemplated by this Agreement, and such limitation shall not
apply in the event that OP closes and thereafter OP or PREIT breaches one or
more of its obligations hereunder after Closing.

         (c) The Inspection Indemnity and the provisions of Section 20 shall
survive Closing or other termination of this Agreement.

                                      35




         24. OTHER PROHIBITED ACTIVITIES.

         (a) From and after the end of the Due Diligence Period and provided
that this Agreement has not been terminated, the Partnership will cease to
market the Property, and, in that regard, the Partnership will refrain from
soliciting or accepting any offer from any third party, or, engaging in any
discussion with any third party concerning the sale, refinancing or
recapitalization of the Property.

         (b) Both OP and the Partnership agree to keep this Agreement
confidential, and not to disclose its contents to anyone except their
respective lenders, legal counsel and accountants, and except to the Partners
in connection with the Offer and except that PREIT may make such public
announcements and may make such filings with the Securities and Exchange
Commission regarding the transaction contemplated by this Agreement, as may,
in its judgment, be required by, or appropriate under, applicable securities
laws.

         25. RISK OF LOSS. Until the Closing, the risk of loss or damage to
all or any part of any Property, from fire or other casualty, or from
condemnation, shall be borne by the Partnership, subject to the terms of this
Agreement.

         26. NOTICES.

         (a) All notices, demands, or requests made and/or given pursuant to,

written consent of either party, such consent to be granted or withheld for

                                      37



         28. GOVERNING LAW. This Agreement shall be governed, construed and
interpreted in accordance with the laws of the Commonwealth of Pennsylvania
applicable to contracts made and to be performed wholly within the
Commonwealth of Pennsylvania without giving effect to the conflicts-of-laws
principles thereof.

         29. ENTIRE AGREEMENT; AMENDMENT. This Agreement and the various
documents referred to herein contains, or incorporates, all of the terms
agreed upon between the parties with respect to the subject matter, and
supersedes any and all prior written or oral understandings. This Agreement
may not be modified or amended except in, and by, a written instrument
executed by the parties hereto.

         30. WAIVER. No waiver by either party of any failure or refusal of
the other party to comply with any of the obligations of such party hereunder
shall be deemed a waiver of any other or subsequent failure or refusal so to
comply.

         31. HEADINGS. The headings of the various sections and articles of
this Agreement have been inserted only for purposes of convenience, and are
not part of this Agreement, and shall not be deemed in any manner to modify,
explain, qualify or restrict any of the provisions of this Agreement.

         32. CONDITION OF APARTMENTS. The Partnership will use commercially
reasonable efforts, in accordance with its existing business practices, to
ensure that at the time of the Closing the vast majority of apartment units
are in rentable condition. The parties recognize that tenants at the Property
move out at various times and that it may not be possible for all units to be
fully prepared at the time of Closing. Accordingly, the Partnership shall be
fully responsible for insuring that all units that have been vacated 10 or
more days prior to Closing shall be in full rentable condition. In the event
that any apartment unit vacant 10 or more days prior to Closing is not in
rentable condition, OP shall receive a closing credit equal to the amount
reasonably necessary to bring that unit to rentable condition based on a
standard typical for the Property. For units vacated within 10 days prior to
Closing, the Partnership will continue to use commercially reasonable efforts,
in accordance with its existing business practices, to prepare such units for
subsequent tenancy, however, if any such units are not in full rentable
condition at the time of Closing there shall be no credit given to OP.

         33. MISCELLANEOUS.

         (a) The Partnership acknowledges that audited financial statements
pertaining to the Property for a minimum of one, and a maximum of three, prior
calendar year(s) of operation, and the portion of the calendar year in which
the Closing occurs, up to the Closing Date, are required to be filed by OP
with the Securities and Exchange Commission after the Closing. Accordingly,
the General Partners shall provide OP, and its representatives, with access to
the books and records of the Partnership pertaining to the Property after the
Closing, upon reasonable advance notice, in order to conduct the required
audit, at the expense of OP.

                                      38




         (b) The parties hereto recognize that, at the Closing Date, the
Partnership will terminate for federal income tax purposes. The General
Partners hereby covenant to cause the tax returns to be prepared for the
Partnership for the period up to the Closing Date. Such tax returns shall be
prepared in a matter consistent with the Partnership's prior returns. The
General Partners will provide OP with a copy of the return at least twenty
days prior to the filing of the return. The General Partners shall make the
Section 754 election on the return. OP shall make available to the General
Partners (and their representatives) promptly upon request, all financial and
other information relating to the Partnership which is necessary to permit the
General Partners to file a tax return on behalf of the Partnership for its
taxable year ended on the Closing Date, and for such other purposes as may be
requested by the General Partners in order to wind up business affairs for the
entity and the Partners.

         (c) Time is of the essence of this Agreement. In the computation of
any period of time provided for in this Agreement, or by law, the day of the
act or event from which the period of time runs shall be excluded, and the
last day of such period shall be included, unless it is a Saturday, Sunday, or
legal holiday, in which case the period shall be deemed to run until the end
of the next day which is not a Saturday, Sunday, or legal holiday.

         (d) The General Partners shall cause tax returns for the Partnership
for the period up to the Closing Date to be completed within one hundred
twenty (120) days of the Closing Date. A copy of such final tax return shall
be submitted to OP twenty (20) days before its filing with the IRS.

         (e) The date upon which this Agreement shall have been signed by both
the Partnership and OP shall be considered to be the date of this Agreement.

         (f) The Partnership and the General Partners agree that they will not
trade in common stock of PREIT, or cause such stock to be traded on their
behalf, prior to the Closing Date.

         (g) This Agreement may be executed in counterparts and by facsimile
signatures.


                                      39




         IN WITNESS WHEREOF, the Partnership, OP and PREIT have executed this
Agreement as at the day and year first above written.
