GUARANTY

                  THIS GUARANTY is made and entered into by PENNSYLVANIA REAL
ESTATE INVESTMENT TRUST, a Pennsylvania business trust form (the "Guarantor"),
for the benefit of CoreStates Bank, N.A., Firstrust Savings Bank, Fleet Bank,
N.A., PNC Bank, National Association, and Summit Bank (the "Banks").

                                  BACKGROUND

                  A. The Guarantor is the sole general partner of Obligor
(as hereinafter defined).

                  B. Pursuant to a Revolving Credit Loan Agreement dated
September 29, 1997 among the Obligor, CoreStates Bank, N.A., as Agent
("Agent") and the Banks (the "Loan Agreement"), the Banks agreed to make
credit facilities available to Obligor. All capitalized terms used but not
specifically defined in this Guaranty have the meanings defined in the Loan
Agreement.

                  C. To induce Banks to make credit facilities available to
Obligor, Banks have required Guarantor to execute and deliver this Guaranty as
a condition precedent thereto.

                  NOW, THEREFORE, intending to be legally bound hereby,
Guarantor agrees as follows:

                  1. OBLIGOR.  The "Obligor" means PREIT Associates, L.P., a
Delaware limited partnership.

                  2. OBLIGATIONS. The "Obligations" means all existing and
hereafter incurred or arising indebtedness, obligations and liabilities of the
Obligor to the Banks, whether absolute or contingent, direct or indirect, and
arising out of the Loan Agreement and the other Loan Documents, and includes,
without limitation, all matured and unmatured indebtedness, obligations and
liabilities of the Obligor under or in connection with existing and future
Advances evidenced by the Notes or otherwise or under Letters of Credit,
including without limitation all interest, expenses, costs (including collection
costs) and fees (including reasonable attorney's fees and prepayment fees)
incurred, arising or accruing (whether prior or subsequent to the filing of any
bankruptcy petition by or against any Obligor) under or in connection with any
of the foregoing. If the term "Obligor" includes more than one person or entity,
the Obligations shall include all Obligations of any one or more of such persons
or entities, whether such Obligations are individual, joint, several or joint
and several.

                  3. UNCONDITIONAL GUARANTY. In consideration of any existing
Obligations and any Obligations which may hereafter arise or be incurred,
Guarantor, intending to be legally bound, absolutely and unconditionally (and
jointly and severally if more than one) guaranties to Banks, and becomes
surety for, the prompt payment, performance and satisfaction when due (whether
by stated maturity, demand, acceleration or otherwise) of all Obligations. The
obligations of Guarantor hereunder shall continue in full force and effect
irrespective of the validity, legality or enforceability of any agreements,
notes or documents pursuant to which any of the Obligations arise, or the
existence, value or condition of any collateral for any of the Obligations, or
of any other guaranty of






the Obligations, or any other circumstance which might otherwise constitute a
legal or equitable discharge of a surety or guarantor.

                  4. COST OF ENFORCEMENT. Guarantor agrees to pay Banks all
costs and expenses (including reasonable attorney's fees) at any time incurred
by or on behalf of Banks in the enforcement of this Guaranty against
Guarantor.

                  5. PAYMENT BY GUARANTOR. Payment by Guarantor is due upon
demand by Banks after the occurrence of an event of default under the
Obligations and is payable in immediately available funds in lawful money of
the United States of America.

                  6. CONTINUING GUARANTY. This Guaranty shall continue in full
force and effect with respect to Guarantor and may not be revoked until all
existing Obligations and all Obligations hereafter incurred or arising have
been paid, performed and satisfied in full.

                  7. WAIVERS AND CONSENTS BY GUARANTOR. Guarantor
unconditionally consents to, and waives as a defense to liability hereunder,
each of the following: (a) any waiver, inaction, delay or lack of diligence by
Agent or Banks or others on behalf of Banks in enforcing its rights against
any Obligor or in any property, or the unenforceability of any such rights,
including any failure to perfect, protect or preserve any lien or security
interest which may be intended directly or indirectly to secure any of the
Obligations, and the absence of notice thereof to Guarantor, (b) the absence
of any notice of the incurrence or existence of any Obligation, (c) any
action, and the absence of notice thereof to Guarantor, taken by Agent or
Banks or any Obligor with respect to any of the Obligations, including any
release, subordination or substitution of any collateral or release,
termination, compromise, modification or amendment of any instrument executed
by or applicable to any Obligor or of any claim, right or remedy against any
Obligor or any property, (d) any impairment of Guarantor's right to
reimbursement by way of subrogation, indemnification or contribution, (e) any
other action taken or omitted by Agent or Banks in good faith with respect to
the Obligations, (f) the absence or inadequacy of any formalities of every
kind in connection with enforcement of the Obligations, including presentment,
demand, notice and protest, and (g) the waiver of any rights of Banks under or
any action taken or omitted by Agent or Banks with respect to any other
guaranty of the Obligations.

                  8. OTHER AGREEMENTS BY GUARANTOR. Guarantor agrees that
there shall be no requirement that Banks document its acceptance of this
Guaranty, evidence its reliance thereon, or that Agent or Banks take any
action against any person or any property prior to taking action against
Guarantor. Guarantor further agrees that Banks' rights and remedies hereunder
shall not be impaired or subject to any stay, suspension or other delay as a
result of any Obligor's insolvency or as a result of any proceeding applicable
to Obligor or Obligor's property under any bankruptcy or insolvency law.
Guarantor also agrees that payments and other reductions on the Obligations
may be applied to such of the Obligations and in such order as Banks may
elect.


                                     (2)



                  9. SUBROGATION AND SIMILAR RIGHTS. Guarantor will not
exercise any rights with respect to Banks or any Obligor related to or
acquired in connection with or as a result of its making of this Guaranty
which it may acquire by way of subrogation, indemnification or contribution,
by reason of payment made by it hereunder or otherwise, until after the date
on which all of the Obligations shall have been satisfied in full. Until such
time any such rights against the Obligor shall be fully subordinate in lien
and payment to any claim in connection with the Obligations which Banks, or
any of them, now or hereafter has against the Obligor. If any amount shall be
paid to Guarantor on account of such subrogation, indemnification or
contribution at any time when all of the Obligations and all other expenses
guaranteed pursuant hereto shall not have been paid in full, such amount shall
be held in trust for the benefit of Banks, shall be segregated from the other
funds of Guarantor and shall forthwith be paid over to Agent to be applied in
whole or in part by Banks against the Obligations, whether matured or
unmatured, in such order as the Banks shall determine in its sole discretion.
If Guarantor shall make payment to Agent or Banks of all or any portion of the
Obligations and all of the Obligations shall be paid in full, Guarantor's
right of subrogation shall be without recourse to and without any implied
warranties by Banks and shall remain fully subject and subordinate to Agent's
and Banks' right to collect any other amounts which may thereafter become due
to the Banks by the Obligor in connection with the Obligations.

                  10. REINSTATEMENT OF LIABILITY. If any claim is made upon
the Banks for repayment or recovery of any amount or amounts received by Banks
in payment or on account of any Obligations and Banks repays all or part of
said amount by reason of (a) any judgment, decree or order of any court or
administrative body having jurisdiction over the Banks or any of its property,
or (b) any settlement or compromise in good faith with any such claimant
(including Obligor), then, and in such event, Guarantor agrees that any such
judgment, decree, order, settlement or compromise shall be binding upon
Guarantor, notwithstanding any termination hereof or the cancellation of any
note or other instrument evidencing any Obligation, and Guarantor shall remain
liable to the Banks hereunder for the amount so repaid or recovered to the
same extent as if such amount had never originally been received by Banks.

                  11. EFFECT OF OTHER AGREEMENTS. The provisions of this
Guaranty are cumulative and concurrent with Agent's or Banks' rights and
remedies against Guarantor under any existing or future agreement pertaining
to or evidencing any of the Obligations. No such additional agreement shall be
deemed a modification or waiver hereof unless expressly so agreed by Banks in
writing. If any Bank holds any other guaranty or surety agreement applicable
to any of the Obligations, the liability of Guarantor hereunder shall be joint
and several with each party obligated on such other guaranty or surety
agreement, unless otherwise agreed by Banks in writing.

                  12. GUARANTOR'S ADDRESS. Guarantor warrants and represents
that the address set forth below is Guarantor's correct mailing address and
agrees immediately to notify Banks in the event of any change therein.

                  13.      MISCELLANEOUS.

                      (b) Any provision of this Guaranty which is prohibited or

remaining portions hereof or affecting the validity or enforceability of such
provisions in any other jurisdiction.

                      (c) The obligations of Guarantor hereunder shall not be
subject to any counterclaim, setoff, deduction or defense based upon any related

Banks or any Obligor, except payment of the Obligations, and shall not be
affected by any change in Obligor's legal status or ownership or by any change
in corporate, partnership or other organizational structure applicable to
Obligor.

                      (d) This Guaranty shall (i) be binding on Guarantor and
its successors and assigns, and (ii) inure, together with all rights and
remedies of Banks hereunder, to the benefit of the Banks and its successors,
transferees and assigns. Notwithstanding the foregoing clause (i), none of the
rights or obligations of any Guarantor hereunder may be assigned or otherwise
transferred without the prior written consent of the Banks.

PROCEEDING IN SUCH COUNTY. THE UNDERSIGNED PARTY AGREES THAT SERVICE OF
PROCESS IN ANY SUCH PROCEEDING MAY BE DULY EFFECTED UPON IT BY MAILING A COPY
THEREOF, BY REGISTERED MAIL, POSTAGE PREPAID, TO THE UNDERSIGNED PARTY.

                  15. WAIVER OF JURY TRIAL. THE UNDERSIGNED HEREBY WAIVES, AND
BANKS BY THEIR ACCEPTANCE HEREOF THEREBY WAIVES, TRIAL BY JURY IN ANY LEGAL
PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN
