                                     NOTE

                                                      Philadelphia, Pennsylvania
$65,000,000                                                   September 30, 1997



                  FOR VALUE RECEIVED, PREIT ASSOCIATES, L.P., a Delaware
limited partnership (the "Borrower") promises to pay to the order of
CoreStates Bank, N.A., a national banking association ("Lender") on or before
the Termination Date (as defined in the Revolving Credit Loan Agreement of
even date by and among Borrower, Lender, CoreStates Bank, N.A., as agent,
Firstrust Savings Bank, Fleet Bank, N.A., PNC Bank, National Association, and
Summit Bank (the "Loan Agreement") with respect to the Facility), the lesser
of (x) Sixty Five Million Dollars ($65,000,000) or (y) Lender's Pro Rata Share
of the unpaid principal amount of all Advances made by the Lenders to the
Borrower under the Loan Agreement, in lawful money of the United States of
America and in immediately available funds. All initially capitalized terms
used herein shall have the same meanings ascribed to them in the Loan
Agreement unless the context clearly requires to the contrary.

                  Borrower also promises to pay interest on the unpaid
principal amount of Lenders' Pro Rata Share of all Advances from the Funding
Date to maturity (whether by acceleration or otherwise) with respect to Base
Rate Loans, at the Base Rate per annum, and with respect to Adjusted LIBOR
Loans, at the sum of the Adjusted LIBOR on the relevant Interest Rate
Determination Date plus the Applicable Margin. The applicable basis for
determining the rate of interest with respect to Advances shall be selected by
Borrower at the time a Notice of Borrowing is given pursuant to Section 2.2.2
of the Loan Agreement or a Notice of Rate Election is given pursuant to
Section 2.2.3 of the Loan Agreement. If on any day an Advance is outstanding
with respect to which notice has not been delivered to Agent in accordance
with the terms of the Loan Agreement specifying the basis for determining the
rate of interest, then such Advance shall bear interest as if a Base Rate
Loan. The rate of interest payable with respect to Adjusted LIBOR Loans shall
be recalculated from time to time in accordance with the provisions of Section
2.14 of the Loan Agreement.

                  Interest shall be payable on the Loans in arrears through
the last Business Day of each month, with the first payment to be made on the
first Business Day of the month next following the Closing Date and continuing
thereafter on the first Business Day of each month and at maturity.

                  Any principal payments on the Loans not paid when due and,
to the extent permitted by applicable law, any interest payment on the Loans
not paid when due, and any other amount due to Agent or Lender under the Loan
Agreement or any other Loan Document not paid when due, in any case whether at
stated maturity, by notice of prepayment, by acceleration or otherwise, shall
thereafter bear interest payable upon demand at a rate which is two percent (2%)






per annum in excess of (i) with respect to Adjusted LIBOR Loans, the applicable
Interest Rate until the expiration of the then applicable Interest Period, and
after the expiration of the then applicable Interest Period at a rate which is
two percent (2%) in excess of the Base Rate and (ii) with respect to Base Rate
Loans, at a rate which is two percent (2%) per annum in excess of the Base Rate.

                  This Note is one of the Notes referred to in the Loan
Agreement and is issued pursuant to and entitled to the benefits of the Loan
Agreement, to which reference is hereby made for a more complete statement of
the terms and conditions on which Lender's Pro Rata Share of the Advances
evidenced hereby and by the other Notes were made and are to be repaid. All
recoveries by Lender under this Note or otherwise are subject to the
provisions of Article 9 of the Loan Agreement.

Note shall be made by Borrower without setoff or counterclaim in immediately
available funds and delivered to Agent not later than 12:00 noon (Philadelphia

Floor, 1339 Chestnut Street, FC 1-8-10-67, Philadelphia, Pennsylvania 19107 or
at such other place as shall be designated in writing for such purpose in
accordance with the terms of the Loan Agreement. Funds received by Agent after
that time shall be deemed to have been paid by the Borrower on the next
succeeding Business Day.

                  Whenever any payment on this Note shall be stated to be due
on a day which is not a Business Day, such payment shall be made on the next
succeeding Business Day and such extension of time shall be included in the
computation of the payment of interest on this Note.

                  Borrower authorizes Agent to charge Borrower's accounts with
Agent (but only to the extent there are sufficient funds therein) in order to
cause timely payment to be made to Agent of all principal, interest and fees
hereunder as provided in Section 1.5 of the Loan Agreement.

principal balance hereof subject to the terms and conditions of the Loan
Agreement.

shall be unconditional without regard to the liability or obligations of any
other party and shall not be in any manner affected by any indulgence
whatsoever granted or consented to by Lender, including, but without being
limited to, any extension of time, renewal, waiver or other modification. Any
failure of Lender to exercise any right hereunder shall not be construed as a
waiver of the right to exercise the same or any other right at any time and
from time to time thereafter.

all notices or demands in connection with the delivery, acceptance,
performance, default or enforcement of this Note.

                  Lender may assign a portion or portions of its rights and
obligations under this Note subject to the terms and conditions of the Loan
Agreement.

balance of the principal amount of this Note, together with all accrued but

may become, or may be declared to be, due and payable in the manner, upon the
conditions and with the effect provided in the Loan Agreement.

but only by an agreement in writing and signed by all Lenders (or by such
number of Lenders as all Lenders may from time to time agree in writing) and
Borrower.

reasonable attorneys' fees, as provided in Section 1.6 of the Loan Agreement,

permitted by law, the right to plead any statute of limitations as a defense
to any demand hereunder.

                  If any provision of this Note shall for any reason be held
to be invalid or unenforceable, such invalidity or unenforceability shall not
affect any other provision hereof, but this Note shall be construed as if such
invalid or unenforceable provision had never been contained herein.
