                                    2.2.2.   Notice of Borrowing.

                                             Subject to the provisions of this
Article 2, whenever Borrower desires to borrow under this Agreement, Borrower
shall deliver by telecopy to Agent a properly completed and executed Notice of
Borrowing with respect to (i) Adjusted LIBOR Loans no later than 11:00 A.M. at
least three (3) London Business Days in advance of the proposed Funding Date,
or (ii) Base Rate Loans no later than 11:00 A.M. at least one (1) Business Day
in advance of the proposed Funding Date. The Notice of Borrowing shall specify
(i) the proposed Funding Date (which shall be a Business Day), (ii) the amount
of the proposed Advance, if any, (iii) whether an Advance is initially to
consist of Base Rate Loans, Adjusted LIBOR Loans or a combination thereof, and
(v) if such Advance, or any portion thereof, is initially to be one or more
Adjusted LIBOR Loans, the amounts thereof and the initial Interest Periods
therefor; provided that the minimum amount of Advances shall be $500,000 for
Base Rate Loans (unless a Base Rate Loan is to be made to a Venture, in which
event the amount thereof may be less than $500,000, provided that no more than
one Advance is made to such Venture in any calendar month) and $2,000,000 for
Adjusted LIBOR Loans, except that at no time shall the aggregate number of
Interest Periods and Base Rate Loans, excluding Venture Loans, that Agent
shall be required to administer at any time exceed eight (8). Subject to the
foregoing limitations, Loans may be continued as or converted into Adjusted
LIBOR Loans in the manner provided in Section 2.2.3 hereof upon the submission
to Lender of a properly completed and executed Notice of Rate Election.

                                             A Notice of Borrowing or a Notice
of Rate Election for an Adjusted LIBOR Loan shall be irrevocable on and after
the related Interest Rate Determination Date, and Borrower shall be bound to
make, continue or convert to an Adjusted LIBOR Loan in accordance therewith.

                                    2.2.3.   Notice of Rate Election; Failure
                                             to Give Notice.

                                             Whenever Borrower desires to
change or continue the Interest Rate Option on a Loan, Borrower shall deliver
to Agent a Notice of Rate Election with respect to Adjusted LIBOR Loans no
later than 11:00 A.M. at least three (3) London Business Days in advance of
the proposed change or continuation. No notice shall be necessary to continue
any Base Rate Loan at the Base Rate. The Notice of Rate Election shall
specify: (i) the proposed date of change or continuation or conversion (which
shall be a Business Day); (ii) the type of Loan and amount thereof affected;
(iii) whether such interest rate change or continuation is to consist of Base
Rate Loans, Adjusted LIBOR Loans or a combination thereof; and (iv) the
Interest Periods therefor, if applicable. If at the termination of any
Interest Period Borrower has failed to submit a Notice of Rate Election, as
aforesaid, to convert or to continue Adjusted LIBOR Loans at the interest rate
that is based on Adjusted LIBOR, then such Adjusted LIBOR Loans shall
automatically be and become Base Rate Loans as of the termination of the
relevant Interest Period.

                                     (18)


                                             Upon the expiration of any
Interest Period applicable to portions of the Facility bearing interest based
on the Adjusted LIBOR, such portions of the Facility shall be deemed repaid
and reborrowed upon the submission to Agent of a properly completed and
executed Notice of Rate Election pertaining thereto within the requisite time
periods for a change or continuation of an Interest Rate Option, and the
succeeding Interest Period(s) of such continued portions of the Facility shall
commence on the first day of the Interest Period of the portions of the
Facility deemed to be reborrowed and continued.

                                             Adjusted LIBOR Loans may be
converted into Base Rate Loans only on the expiration date of an Interest
Period applicable thereto. In addition, no outstanding portions of the
Facility may be continued as, or be converted into, Adjusted LIBOR Loans when
any Event of Default or Unmatured Event of Default has occurred and is
continuing.

                                             If on any day portions of the
Facility are outstanding with respect to which a Notice of Rate Election has
not been delivered to Agent in accordance with the terms of this Agreement
specifying the basis for determining the Interest Rate Option, then such
portions of the Facility shall bear interest at the Base Rate.

                                    2.2.4.   Funding. By 5:00 p.m. on the day
Agent receives a Notice of Borrowing pursuant to Section 2.2.2, Agent shall
notify each Lender by facsimile transmission of the proposed borrowing. Except
as provided in the following paragraph of this Section 2.2.4, upon
satisfaction of the conditions precedent specified in Sections 4.1 (in the
case of the initial Advances) and 4.2 (in the case of all subsequent
Advances), not later than 11:00 A.M. on the Funding Date specified in the
Notice of Borrowing each Lender shall wire transfer to such account of Agent
as Agent shall designate an amount in immediately available funds equal to the
amount of each Lender's Pro Rata Share of the Advance to be made to Borrower
on such Funding Date. Agent shall cause such Advances to be made available to
Borrower on the Funding Date pertaining thereto by depositing the amount
thereof in the designated account of Borrower with Agent.

                  Each Lender shall make the amount of its Pro Rata Share of
the Advance available to Agent, in same day funds at the office of Agent
located at Broad and Chestnut Streets, Philadelphia, Pennsylvania, 19101, not
later than 11:00 A.M. on the Funding Date. Unless Agent shall have been
notified by any Lender prior to any Funding Date in respect of any Advances
that such Lender does not intend to make available to Agent such Lender's Pro
Rata Share of the Advance on such Funding Date, Agent may assume that such
Lender has made such amount available to Borrower on such Funding Date and
Agent in its sole discretion may, but shall not be obligated to, make
available to Borrower a corresponding amount on such Funding Date by
depositing the proceeds thereof in the designated Deposit Account of Borrower
with Agent. If any Lender's Pro Rata Share is not in fact made available
(either by a wire transfer to Agent or otherwise) to Agent by such Lender,
Agent shall not be required to advance to Borrower on the Funding Date any
amount not made available to Agent by a Lender; provided, that if Agent (or
any other Lender(s)) advances to Borrower on the Funding Date any amount not
made available to Agent by a Lender, Agent (or such Lender) shall notify


                                     (19)


Borrower that Agent (or such Lender) has advanced more than its Pro Rata Share
of such Advance and that such Advance is subject to reclamation in accordance
with the provisions of this Section. Any amount so advanced shall be deemed to
be an Advance which Borrower is obligated to repay as set forth under this
Agreement; and Agent shall be entitled to recover such corresponding amount on
demand from such Lender together with interest thereon, for each day from such
Funding Date until the date such amount is paid to the Agent at the daily
average Federal Funds Effective Rate for such period. If such Lender does not
pay such corresponding amount forthwith upon the Agent's demand therefor, the
Agent shall promptly notify the Borrower and the Borrower shall immediately
pay such corresponding amount to the Agent, together with interest at the
Interest Rate Option chosen by Borrower for such Advance. If such Advance was
in the form of an Adjusted LIBOR Loan, any prepayment penalty under Section
2.2.8.1 for breakage of an Interest Period shall be paid by the Lender which
failed to fund its Pro Rata Share of such Advance.

                  In the event that any Lender fails to advance its Pro Rata
Share of any Advance, then such Lender's Pro Rata Share of the aggregate
principal, interest, fees and recoveries on all Advances will be reduced so as
to be proportionate to the amount such Lender did advance but will not cause a
comparable reduction in such Lender's Pro Rata Share of the expenses of
collection of the Indebtedness from Borrower or other costs or expenses
relating to this Agreement. Such reduction will not affect or limit such
Lender's obligation to advance its full Pro Rata Share of any and all future
Advances or other obligations.

                                    2.2.5.   Interest Periods.

                                             In connection with each Adjusted
LIBOR Loan, Borrower shall elect an Interest Period to be applicable to such
Loan, which Interest Period shall be either a one, two, three, or six month
period; provided that:

                                             2.2.5.1. the first Interest
Period for any Adjusted LIBOR Loan shall commence on the Funding Date of such
Adjusted LIBOR Loan;

                                             2.2.5.2. except as provided in
subsection 2.2.5.3 hereof, if an Interest Period would otherwise expire on a
day which is not a Business Day, such Interest Period shall expire on the next
succeeding Business Day;

                                             2.2.5.3. any Interest Period in
respect of an Adjusted LIBOR Loan which: (i) begins on the last Business Day
of a calendar month (or a day for which there is no numerically corresponding
day in the calendar month at the end of such Interest Period) shall end on the
last Business Day of the relevant calendar month, or (ii) would expire on a
day which is not a Business Day but is a day of the month after which no
further Business Day occurs in that month, such Interest Period shall expire
on the last Business Day of the month;

                                             2.2.5.4. no Interest Period, with
respect to any Loan, shall extend beyond the Termination Date.

                                     (20)


                                    2.2.6.   Post-Maturity Interest.

                                             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 Lenders under this 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 (i) 2% per annum in excess of the applicable Interest Rate
on each Adjusted LIBOR Loan until the expiration of the then applicable
Interest Period, if any, and (ii) after the expiration of the then applicable
Interest Period, if any, and on all Base Rate Loans, at a rate which is 2% per
annum in excess of the Base Rate.

                                    2.2.7.   Adjusted LIBOR and Base Rate.

                                             2.2.7.1. Agent shall give
Borrower prompt notice of the Adjusted LIBOR determined for an Interest
Period, and absent manifest error, each determination of such rates by Agent
shall be conclusive and binding for all purposes hereof.

                                             2.2.7.2. If Borrower requests
that all or any portion of the outstanding Facility bear interest at the
Adjusted LIBOR and (i) Agent determines that, by reason of circumstances
affecting the interbank Eurodollar market generally, deposits in U.S. Dollars
(in the applicable amounts) are not being offered to banks in the interbank
Eurodollar market for the selected Interest Period, or (ii) the Requisite
Lenders certify that the relevant rates of interest referred to in the
definition of Adjusted LIBOR do not accurately reflect the cost to Lenders of
making or maintaining Adjusted LIBOR Loans for the Interest Periods therefor,
then Agent shall forthwith give notice thereof to Borrower, whereupon until
Agent notifies Borrower that the circumstances giving rise to such suspension
no longer exist, (a) the obligation of Lenders to permit applicable portions
of the Facility to bear interest at the Adjusted LIBOR shall be suspended so
long as such circumstances exist, and (b) Borrower shall convert the interest
rates on the applicable portions of the outstanding Facility to the Base Rate
or the available Adjusted LIBOR on the last day of the then current Interest
Period.

                                             2.2.7.3. If, after the date of
this Agreement, the adoption of or any change in Rules, or change in the
interpretation or administration thereof, by a governmental authority, central
bank or comparable agency charged with the interpretation or administration
thereof, or compliance by Lenders with any request or directive (whether or
not having the force of law) of any such authority, central bank or comparable
agency shall make it unlawful or impossible for any Lender to make or maintain
or fund loans at the Adjusted LIBOR, the affected Lender or Lenders shall
promptly notify Borrower and the interest rates on the applicable portions of
the outstanding Facility shall be deemed to have been converted to the Base
Rate, or the Adjusted LIBOR, whichever is available, on either (i) the last
day of the then current Interest Period if the affected Lenders may lawfully
continue to maintain loans at the Adjusted LIBOR to such day, or (ii)
immediately if the affected Lender may not lawfully continue to maintain loans
at the Adjusted LIBOR to such day. The affected Lenders will use their best


                                     (21)


efforts to designate a different lending office if such office may lawfully
continue to maintain loans at the Adjusted LIBOR through the end of the then
current Interest Period. After Borrower's receipt of notice of the illegality
or impossibility for any Lender to make, maintain or fund loans at the
Adjusted LIBOR, Borrower shall not request future Adjusted LIBOR Loans until
the affected Lender or Lenders shall have notified Borrower of the absence or
removal of such illegality or impossibility.

                                             2.2.7.4. If, after the date of
this Agreement, any governmental authority, central bank or other comparable
authority shall at any time impose, modify or deem applicable any reserve
(including, without limitation, any imposed by the Board of Governors of the
Federal Reserve System), any tax (including without limitation, any United
States interest equalization tax or similar tax however named applicable to
the acquisition or holding of debt obligations and any interest or penalties
with respect thereto), duty, charge, fee, deduction, withholding, special
deposit or similar requirement against assets of, deposits with, or for the
account of, or credit extended by, any Lender, or shall impose on any Lender
or the interbank Eurodollar market any other condition affecting loans at the
Adjusted LIBOR, and the result of any of the foregoing is to increase the cost
to any Lender of making or maintaining the interest rate at the Adjusted LIBOR
or to reduce the amount of any sum received or receivable by any Lender under
this Agreement, the Notes or the Venture Notes by an amount deemed by such
Lender to be material, then within five days after demand by such Lender,
Borrower shall pay to such Lender such additional amount or amounts as will
compensate Lender for such increased cost or reduction. Each affected Lender
will promptly notify Borrower and Agent of any event of which it has knowledge
occurring after the date hereof, which will entitle such Lender to
compensation pursuant to this subsection 2.2.7.4. A certificate of any Lender
claiming compensation under this subsection 2.2.7.4 and setting forth the
additional amount or amounts to be paid to such Lender hereunder shall be
conclusive in the absence of manifest error.

                                             2.2.7.5. The Adjusted LIBOR shall
be adjusted automatically on and as of the effective day of any change in the
relevant Reserve Percentage.

                                             2.2.7.6. Promptly upon notice
from Agent to Borrower, Borrower will pay, prior to the date on which
penalties attach thereto, all present and future stamp, documentary and other
similar taxes, levies, or costs and charges whatsoever imposed, assessed,
levied or collected on or in respect of the Loans solely as a result of the
interest rate being determined by reference to the Adjusted LIBOR and/or the
provisions of this Agreement relating to the Adjusted LIBOR and/or the
recording, registration, notarization or other formalization of any thereof
and/or payments of principal, interest or other amounts made on or in respect
of a Loan when the interest rate is determined by reference to the Adjusted
LIBOR (all such taxes, levies, costs and charges being herein collectively
called "Eurodollar Rate Tax"). Promptly after the date on which payment of any
such Eurodollar Rate Tax is due pursuant to applicable law, Borrower will, at
the request of Agent, furnish to Agent evidence, in form and substance
satisfactory to Agent, that Borrower has met its obligation under this
subsection 2.2.7.6. Borrower will indemnify each Lender against, and reimburse


                                     (22)


each Lender on demand for, any Eurodollar Rate Tax, as determined by such
Lender in its good faith discretion. Each such Lender shall provide Borrower
with appropriate receipts for any payments or reimbursements made by Borrower
pursuant to this subsection 2.2.7.6. A certificate of Agent or of any Lender
as to any amount payable pursuant to this Section shall, absent manifest
error, be final, conclusive and binding on all parties hereto.

                                             2.2.7.7. If Agent or any Lender
shall determine that (i) any current Rule, law, regulation, or guideline, the
adoption or imposition of any Rules, law, regulation, or guideline any change
in any Rules, law, regulation or guideline, or the adoption, imposition or
change in the interpretation or administration thereof by a governmental
authority, central bank or comparable agency charged with the interpretation
and administration thereof, or (ii) compliance by any Lender (or any lending
office or any holding company of any Lender) with any request, guideline or
directive whether or not having the force of law regarding special deposit,
capital adequacy, risk based capital, capital or reserve maintenance, capital
ratio, or similar requirements against loans or loan commitments or any
commitments to extend credit or other assets of or any deposits or other
liabilities taken or entered into by any Lender (including the capital
adequacy guidelines promulgated by the Board of Governors of the Federal
Reserve System) and the result of any event referred to in clauses (i) or (ii)
above (x) shall be to increase the cost to Lender of making or maintaining, or
to impose upon any Lender or increase any capital requirement applicable as a
result of the making or maintenance of, the Loans or the obligation of
Borrower hereunder or (y) has or would have the effect of reducing the rate of
return or amounts receivable hereunder on any Loan as a consequence of any
Lender's obligations pursuant to this Agreement or Loans made by any Lender
pursuant hereto to a level below that which such Lender (or such Lender's
holding company) could have achieved but for such adoption, imposition, change
or compliance (taking into consideration such Lender's policies and the
policies of such Lender's holding company with respect to capital adequacy) by
an amount deemed by such holder to be material (which adoption, imposition,
change, or increase in capital requirements or reduction in amounts receivable
may be determined by such Lender's reasonable allocation of the aggregate of
such cost increase, capital increase or imposition or reductions in amounts
receivable resulting from such events), then, from time to time, Borrower
shall pay to such Lenders, on demand by such Lender as set forth below, such
additional amount or amounts as will be necessary to restore the rate of
return to such Lender from the date of such change, together with interest on
such amount from the date demanded until payment thereof in full at the rate
provided in this Agreement. Each Lender (or each Lender's holding company)
shall be entitled to compensation pursuant to this Section 2.2.7.7. A
certificate of any Lender claiming compensation under this Section 2.2.7.7 and
setting forth the increased cost, reduction in amounts receivable, additional
amount or amounts necessary to compensate such Lender (or such Lender's
holding company) hereunder shall be delivered to Borrower and shall be
conclusive in the absence of manifest error. Borrower shall pay each Lender
the amount shown as due on any such certificate delivered by such Lender
within 10 days after Borrower's receipt of same. If any Lender demands
compensation under this Section 2.2.7.7, Borrower may, upon 10 Business Days'
prior notice to Lender, prepay in full, in accordance with Section 2.2.8
hereof, the then outstanding: (i) Base Rate Loans together with accrued
interest thereon to the date of prepayment without penalty; and (ii) Adjusted


                                     (23)


LIBOR Loans, together with accrued interest thereon to the date of prepayment
along with a prepayment premium in an amount equal to the amount of any loss
or expense, including loss of margin, actually incurred by such Lender as a
direct result of such prepayment, as determined by such Lender in good faith,
in each case payable to such Lender. Concurrently with prepaying such Base
Rate Loans or Adjusted LIBOR Loans, Borrower may, subject to the terms of this
Agreement, borrow from Lenders Advances at an Interest Rate Option not so
affected.

                                             2.2.7.8. Failure on the part of
any Lender to demand compensation for any increased costs or reduction in
amounts received or receivable or reduction in return on capital with respect
to any period shall not constitute a waiver of such Lender's right to demand
compensation with respect to such period or any other period. The protection
of this Section 2.2.7 shall be available to Lenders regardless of any possible
contention of the invalidity or inapplicability of the law, rule, regulation,
guideline or other change or condition which shall have occurred or been
imposed.

                                             2.2.7.9. The Base Rate shall be
determined and adjusted daily.

                                    2.2.8.   Prepayment; Repayments;
                                             Prepayment Premium.

                                             2.2.8.1. Voluntary Prepayments.
All prepayments shall be applied among the Lenders in accordance with the Pro
Rata Share of each. In connection with each prepayment:

                                             (a) Borrower shall provide Agent
with at least one (1) Business Day prior notice of Borrower's intention to
prepay, specifying the amount and date of such payment.

                                             (b) Borrower shall concurrently
with any prepayment in full of the Facility pay the full amount of all
interest accrued on the Facility and accrued fees (including without
limitation the Unused Fee attributable to the expired portion of the period
with respect to which such fees have not yet been paid), and payments received
shall be applied first to fees, then to accrued interest and thereafter in
reduction of principal.

                                             (c) Each prepayment of principal
shall be in an amount not less than One Million Dollars ($1,000,000.00)
(exclusive of the interest and fees payable in connection therewith and of the
other amounts payable pursuant to this Agreement upon a prepayment).

                                             (d) Borrower acknowledges that if
Borrower makes a prepayment of any Adjusted LIBOR Loan (whether voluntary or
mandatory), Lenders will not likely be able to reinvest promptly the amount so
prepaid in a loan of comparable creditworthiness and on terms equivalent to
the terms hereof. Accordingly, in the event Borrower makes a prepayment


                                     (24)


(whether voluntary or mandatory) of any portion of the Loans bearing interest
at a rate based on the Adjusted LIBOR during a specified Interest Period on a
day other than the last day of such Interest Period, Borrower will pay to the
Agent upon demand, for the account of the Lenders, any cost or expense
incurred as a result of such prepayment. Each Lender shall certify the amount
of such cost or expense to Borrower and provide Borrower with a written
statement setting forth the cost or expense claimed and the calculations used
in determining such loss and expense, which certification and statement shall
be conclusive in the absence of manifest error.

                                             Prepayments shall be applied
first to interest (to the extent then payable), then to principal with respect
to the portions of the Loans accruing interest at a rate based upon the Base
Rate, and then to principal with respect to those portions of the Loans
accruing interest at a rate based upon the Adjusted LIBOR and among such
portions of the Loans accruing interest at rates based upon the Adjusted LIBOR
to such portions with the earliest expiring Interest Periods.

                                             2.2.8.2. Funding Losses. If the
Borrower fails to borrow any Adjusted LIBOR Loans after a Notice of Borrowing
or Notice of Rate Election has been given to Lender as provided in this
Article 2, Borrower shall reimburse each Lender, on demand, for any resulting
loss or expense incurred by it (or by any existing or prospective participant
in the related Loan), including (without limitation) any loss incurred in
obtaining, liquidating or employing deposits from third parties, provided that
such Lender shall have delivered to the Borrower a certificate as to the
amount of such loss or expense and specifying the calculation thereof, which
certificate shall be conclusive in the absence of manifest error.

                                             2.2.8.3. Termination or Reduction
in Commitments. Borrower shall have the right without premium or penalty
except as provided in Section 2.2.8.1 hereof, upon not less than three (3)
Business Days' prior written notice to Agent, at any time after the Closing
Date to reduce or terminate any or all of the commitments of Lenders regarding
the Facility. Any voluntary termination or reduction in the Commitment Amount
shall permanently reduce the Commitment Amount. No such reduction in
Commitment Amount shall be in an amount less than $3,000,000. If Borrower
desires to terminate or reduce the Commitment Amount as aforesaid, Borrower
shall execute and deliver to Agent such documents and instruments as Agent
shall require. No reduction of the Commitment Amount pursuant to this Section
2.2.8.3 shall reduce any Lender's Pro Rata Share of the reduced Commitment
Amount.

                                    2.2.9.   Manner and Time of Payment.

                                             All payments of principal,
interest and fees hereunder and under the Notes shall be made by Borrower
without notice, set off or counterclaim and in immediately available same day
funds and delivered to Agent not later than 12:00 noon on the date due at its

19101 for the account of Lenders; funds received by Agent after that time

                                     (25)


                                    2.2.10.  Apportionment of Payments.

                                             Aggregate principal and interest
payments in respect of Loans shall be apportioned among all outstanding Loans
to which such payments relate, proportionately to each Lender's respective Pro
Rata Share except to the extent a Lender fails to fund its portion of such
Loan (in which case such Lender shall be entitled to a portion of principal
and interest payments determined with respect to the ratio of Loans made by it
to all outstanding Loans). Agent shall within one Business Day distribute by
wire transfer to each Lender its share of all payments received by Agent for
the benefit of Lenders, provided that immediately available same day funds
received by Agent not later than noon on a Business Day shall be distributed
to Lenders on such Business Day.

                                    2.2.11.  Use of Proceeds.

                                             The Facility shall be used solely
by Borrower (i) to finance the acquisition, expansion and renovation of real
estate assets wholly-owned by Borrower, (ii) to refinance existing
indebtedness, (iii) for its working capital purposes (including without
limitation for investments in and loans to Ventures), and (iv) to fulfill
Borrower's obligations to Ventures to obtain Venture Loans.

                                    2.2.12.  Maximum Available Credit.

                                             Notwithstanding anything herein
to the contrary, the maximum amount of the Loans to Borrower that may be
outstanding at any one time shall not exceed the Commitment Amount, less (i)
the aggregate maximum amount of all Venture Loans then outstanding (including
all unfunded portions thereof), and (ii) the face amount of all outstanding
Letters of Credit.

                                    2.2.13.  Postponement of Termination Date.

                                             2.2.13.1. If Borrower's Leverage
Ratio is, at any time prior to December 31, 1998, less than 50% (i) the
Termination Date shall automatically be postponed to December 31, 2000 and
(ii) Borrower shall have the right to request subsequent postponements of the
Termination Date by written notice received by Agent not earlier than the date
Agent receives the financial statements due pursuant to Section 6.1.9 hereof
in the year such request is made or later than the November 1st of the
calendar year immediately preceding the year in which the then-current
Termination Date occurs. Any such request shall be to extend the Termination
Date by 12 months. Agent shall advise Borrower in writing, not later than 60
days after the later to occur of (i) Agent's receipt of such request or (ii)
Agent's receipt of the financial statements due pursuant to Section 6.1.9
hereof during the calendar year immediately preceding the then-current
Termination Date, whether all Lenders have approved such request, which
approval shall be in Lenders' sole discretion. Each Lender shall advise Agent
in writing, not later than five (5) days before Agent's response to Borrower
is required, whether such Lender approves Borrower's request. If all Lenders


                                     (26)


approve such request, the Termination Date shall be postponed for 12 months
and Borrower, Agent and Lenders shall promptly execute and deliver such
documentation Agent may require to evidence such postponement. If Agent does
not give Borrower written notice of Lenders' approval of the requested
postponement, the then-current Termination Date shall remain unchanged.

                                             2.2.13.2. In the event that
Requisite Lenders, but not all Lenders, approve Borrower's request (such
Lenders that do not approve such request being "Refusing Lenders"), Borrower
may elect to seek to obtain a replacement lender or lenders (which may be one
or more of Lenders or may be another institution acceptable to Agent in good
faith) to purchase the Refusing Lenders' Pro Rata Shares of the Facility and
to become a Lender hereunder. Upon written request of Borrower and Agent, each
Refusing Lender shall assign to the designated replacement Lender(s) all or
any portion of the Refusing Lender's Pro Rata Share of the Facility (provided
that the interest of a replacement Lender in the Facility may not be less than
$10,000,000), such assignment to be without recourse or warranty by the
Refusing Lender, other than a warranty of title to the assigned interest in
the Facility, and to be effected by an instrument of assignment in the form
attached hereto as Schedule 2.2.13.2. If substitute Lenders are so obtained
and the Pro Rata Shares of all Refusing Lenders so assigned by the September
30th immediately preceding the then-current Termination Date, the Termination
Dates shall be postponed to December 31st of the next calendar year;
otherwise, there shall be no postponement of the then-current Termination
Date.

                                  3. SECURITY

                           3.1.     Mortgages.

                                    As security for its obligations under this
Agreement and the Notes, Borrower shall execute, acknowledge and deliver to 
Agent a Mortgage with respect to each Property that is part of the
Initial Unencumbered Property Pool and an assignment of rents, leases and
profits and UCC-1 Financing Statements with respect to each such Property.
Borrower shall cause the General Partner to execute, acknowledge and deliver
to Agent the Mortgage, assignment of rents, leases and profits and UCC-1
Financing Statements pertaining to each Property in the Initial Unencumbered
Property Pool in which the General Partner holds legal title. Such Mortgages
shall be in the aggregate amount of the initial Commitment Amount, allocated
among such Properties as Borrower and Lenders have agreed. Within five (5)
Business Days after written notice by Agent from time to time, Borrower shall
re-execute and acknowledge the Mortgages and deliver the same to Agent.



                                     (27)


                           3.2.     Recording of Mortgages.

                                    3.2.1.   Agent's Right to Record.

                                             Agent and Lenders agree that no
Mortgage nor any assignment of rents, leases and profits or UCC-1 Financing
Statements will be recorded by or at the direction of Agent or Lenders unless
(i) any Event of Default occurs or (ii) at any time (A) the aggregate maximum
principal amount of all then existing outstanding construction loans (other
than non-recourse construction loans) with respect to which (I) Borrower or
any Venture is the borrower and (II) Requisite Lenders have, in the aggregate,
less than a 51% of the lender's interest, exceeds (B) the maximum amount of
Other Indebtedness then permitted under this Agreement, or (iii) as of or
before December 31, 1998, Agent's right to record Mortgages has not been
terminated as set forth in Section 3.2.2 hereof. Upon the occurrence of any of
the foregoing events, Agent shall promptly cause the Mortgages and such
assignments of rents, leases and profits and UCC-1 Financing Statements to be
recorded. If Agent is authorized to record, and does record, any or all of the
Mortgages and other security instruments, all costs incurred by Agent in the
recording of Mortgages and such other security instruments (including, without
limitation, mortgage, documentary or recording stamps or taxes, and all other
taxes payable by Agent by reason of its holding a Note that is secured by
Mortgages) shall be Lenders' Costs, shall be paid or reimbursed by Borrower
upon demand, and shall be secured by the Mortgages.

                                    3.2.2.   Termination of Agent's Right to
                                             Record.

                                             If (i) no event shall theretofore
have occurred that would, pursuant to Section 3.2.1 hereof, permit Agent to
record the Mortgages and, (ii) as of or before December 31, 1998, (A)
Borrower's Leverage Ratio is not more than 50% and the ratio (expressed as a
percentage) of Borrower's Senior Liabilities to Unencumbered Asset Value is
not more than 60% and (B) Borrower has delivered to Agent written notice that
Borrower elects that Agent's right to record the Mortgage be terminated, Agent
shall have no right thereafter to record any Mortgage and shall promptly
return to Borrower all Mortgages theretofore delivered to Agent pursuant to
this Agreement. If Agent's right to record the Mortgage has not so terminated
by December 31, 1998, Agent shall record the Mortgages and the other documents
referred to in Section 3.1 hereof. If Borrower satisfies the requirements of
the aforesaid clause (ii)(A) but shall not deliver the notice required
pursuant to clause (ii)(B), Borrower may, at its election, thereafter deliver
such notice to Agent and the same shall be deemed to be effective as of the
date of Agent's actual receipt thereof, but only if no Event of Default has
theretofore occurred and only if Borrower has not theretofore delivered to
Agent a subsequent Covenant Compliance Certificate indicating that Borrower no
longer satisfies the requirements of clause (ii)(A). For purposes of
determining whether Borrower has satisfied the requirements of the aforesaid
clause (ii)(A) "as of December 31, 1998," Agent shall adjust Borrower's
Company Prepared Financial Statements as of September 30, 1998 for any
offering of equity securities consummated by Borrower or the General Partner
after September 30, 1998, and if Borrower shall satisfy the requirements of
clause (ii)(A) as of December 31, 1998, and no event has theretofore occurred


                                     (28)


that would, under Section 3.2.1 hereof, permit Agent to record the Mortgages,
Agent's right to record the Mortgages shall automatically terminate without
notice from Borrower.

                           3.3      Removals from and Additions to
                                    Unencumbered Property Pool.

                                    3.3.1 Prior to the recording of Mortgages
pursuant to Section 3.2 hereof, Agent shall, within ten (10) Business Days
after each written request by Borrower to Agent, return to Borrower the
Mortgage with respect to any Property within the Unencumbered Property Pool,
provided that (i) such Property shall, retroactively as of the last day of the
most recently concluded Calendar Quarter, no longer be deemed to be part of
the Unencumbered Property Pool, (ii) as a result of the removal of such
Property from the Unencumbered Property Pool the covenant contained in Section
6.1.3 hereof would not have been breached as of the last day of the most
recently concluded Calendar Quarter, and (iii) at no time shall there be fewer
than five (5) Properties in the Unencumbered Property Pool, the combined
average occupancy of which is at least 85%. If a Property is requested to be
removed from the Unencumbered Property Pool in connection with its sale, the
Mortgage will be returned to Borrower concurrently with the closing of such
sale and, for purposes of determining Borrower's continued compliance with
Section 6.1.3 hereof following removal of such Property from the Unencumbered
Property Pool, the sale will be deemed to have occurred on the last day of the
most recently concluded Calendar Quarter.

                                    3.3.2. Borrower may at any time, in
connection with the return of a Mortgage by Agent pursuant to Section 3.3.1
hereof, or otherwise, add Properties to the Unencumbered Property Pool by
executing, acknowledging and delivering to Agent a Mortgage encumbering a
Substituted Unencumbered Property and an assignment of rents, leases and
profits and UCC-1 Financing Statements with respect to such Property, and such
Property will thereupon become part of the Unencumbered Property Pool,
provided that (i) the Substituted Unencumbered Property, in the good faith
determination of Agent and Required Lenders, is of like quality to the
Properties that are then part of the Unencumbered Property Pool, (ii) the
Substituted Unencumbered Property will be deemed to have been added to the
Unencumbered Property Pool as of the last day of the most recently concluded
Calendar Quarter for purposes of determining compliance with the covenant
contained in Section 6.1.3 hereof, (iii) the Property that is to become part
of the Unencumbered Property Pool must be free of all liens and encumbrances,
other than Permitted Liens, and (iv) no Property shall be a Substituted
Unencumbered Property unless Agent has received such environmental reports
with respect to such Property as Agent in good faith requires and such reports
are acceptable to Agent and Required Lender in the good faith exercise of
their business judgment.

                 5. BORROWER'S REPRESENTATIONS AND WARRANTIES.

                           5.1.     Borrower represents and warrants
                                    to each Lender as follows:

                                    5.1.1.   Good Standing.

                                             Borrower is a limited partnership
organized under the laws of the State of Delaware; has the power and authority
to own and operate Borrower's Properties and to carry on Borrower's Business
where and as contemplated; and is duly qualified to do business in, and is in
good standing in, every jurisdiction where the nature of Borrower's Business
requires such qualification.

                                             The General Partner is a "real
estate investment trust" as defined in Section 856 of the Code and is an
unincorporated association in business trust form duly organized and validly
existing under the laws of the Commonwealth of Pennsylvania.

                                    5.1.2.   Power and Authority.

                                             The making, execution, issuance
and performance by Borrower and the General Partner of this Agreement, the
Notes, the Mortgages, and the other Loan Documents to which Borrower or the
General Partner is a party, have been duly authorized by all necessary action
and will not violate any provision of law or regulation or of the partnership
or trust agreement of Borrower or the General Partner; will not violate any
agreement, trust or other indenture or instrument to which Borrower or the
General Partner is a party or by which Borrower or the General Partner or any
of their respective property is bound. This Agreement, the Notes, the
Mortgages and the other Loan Documents have been duly executed and delivered
by Borrower and the General Partner and constitute legal, valid and binding
obligations of Borrower and the General Partner, respectively, enforceable in
accordance with their respective terms.

                                     (32)


                                    5.1.3.   Financial Condition.

                                             5.1.3.1. The audited balance
sheet of the General Partner, together with income and surplus statements as
at and for the General Partner's fiscal year ended August 31, 1996, and the
unaudited balance sheet of the General Partner, together with income and
surplus statements as at and for the nine months ended May 31, 1997 heretofore
furnished to Agent are complete and correct in all respects, have been
prepared in accordance with GAAP, consistently applied, and fairly present the
financial condition of the General Partner as of said dates and the results of
the General Partner's operations for the periods then ended. Except as set
forth on such financial statements, the General Partner does not have any
fixed, accrued or contingent obligation or liability for taxes or otherwise
that is not disclosed or reserved against on its balance sheets. The General
Partner has filed all federal, state and local tax returns required to be
filed by it with any taxing authority. Since May 31, 1997, there has been no
material adverse change in the condition of the General Partner's financial
position or otherwise from that set forth in the balance sheet as of said
date, other than the acquisition by the Borrower of The Rubin Organization,
Inc. and certain of its assets. Borrower does not believe, in the exercise of
reasonable business judgment, that there has been or will likely be a change
relating to the business of the General Partner that would cause a Materially
Adverse Effect on the General Partner. Borrower is not aware of any additional
tax assessment or tax to be assessed that would have a Material Adverse Effect
on the financial condition of the General Partner.

                                             5.1.3.2. The audited balance
sheet of Borrower, together with income and surplus statements as at and for
Borrower's Last Reported Fiscal Year are complete and correct in all respects,
have been prepared in accordance with GAAP, consistently applied, and fairly
present the financial condition of the Borrower as of said dates and the
results of Borrower's operations for the periods then ended. Except as set
forth on such financial statements, Borrower does not have any fixed, accrued
or contingent obligation or liability for taxes or otherwise that is not
disclosed or reserved against on its balance sheets. Borrower has filed all
federal, state and local tax returns required to be filed by it with any
taxing authority. Since the date of such Financial Statements, there has been
no material adverse change in the condition of Borrower's financial position
or otherwise from that set forth in the balance sheet as of said date.
Borrower does not believe, in the exercise of reasonable business judgment,
that there has been or will likely be a change relating to the Business of
Borrower that would cause a Materially Adverse Effect on Borrower. Borrower is
not aware of any additional tax assessment or tax to be assessed that would
have a Material Adverse Effect on the financial condition of Borrower. The

defend, and hold harmless Lenders and Lenders' directors, officers, employees,
agents, attorneys and shareholders from and against any and all losses,
damages, expenses or liabilities of any kind or nature and from any suits,
claims, or demands, including all reasonable counsel fees incurred in
investigating, evaluating or defending such claim, suffered by any of them and
caused by, relating to, arising out of, resulting from, or in any way
connected with this Agreement, the Notes, the Loans, the Venture Notes, the
Turren Note, the other Loan Documents and any transaction contemplated herein
or therein including, but not limited to, claims based upon any act or failure
to act by Agent and Lenders in connection with this Agreement, the Notes, the
Loans, the Venture Notes, the Turren Note, the other Loan Documents and any
transaction contemplated herein or therein; provided that Borrower shall not
be liable for any portion of such losses, damages, expenses or liabilities
resulting from any Lender's gross negligence or willful misconduct or that of
any Lender's directors, officers, employees, agents, attorneys and
shareholders or from any Lender's default under this Agreement. If Borrower
shall have knowledge of any claim or liability hereby indemnified against, it
shall promptly give written notice thereof to Agent for transmittal to
Lenders. THIS COVENANT SHALL SURVIVE PAYMENT OF THE INDEBTEDNESS.

                           6.2.1. Agent shall promptly give Borrower written
notice of all suits or actions instituted against Lenders with respect to
which Borrower has indemnified Lenders, and Borrower shall timely proceed to
defend any such suit or action. Lenders shall also have the right, at the
expense of Borrower, to participate in or, at Lenders' election, assume the
defense or prosecution of such suit, action, or proceeding, and in the latter
event Borrower may employ counsel and participate therein. Each Lender shall
have the right to adjust, settle, or compromise any claim, suit, or judgment
after notice to Borrower, unless Borrower desires to litigate such claim,
defend such suit, or appeal such judgment and simultaneously therewith
deposits with Agent collateral security sufficient to pay any judgment
rendered, with interest, costs, legal fees and expenses; and the right of
Lenders to indemnification under this Agreement shall extend to any money paid
by Lenders in settlement or compromise of any such claims, suits, and
judgments in good faith, after notice to Borrower.

                           6.2.2. If any suit, action, or other proceeding is
brought by Lenders against Borrower for breach of Borrower's covenant of
indemnity herein contained, separate suits may be brought as causes of action
accrue, without prejudice or bar to the bringing of subsequent suits on any
other cause or causes of action, whether theretofore or thereafter accruing.

Lenders at law or in equity or under this Agreement, the Notes and any of the

                           The remedies provided herein, in the Notes and in
the other Loan Documents or otherwise available to Lender at law or in equity
and any warrants of attorney therein contained, shall be cumulative and
concurrent, and may be pursued singly, successively or together at the sole
discretion of Agent, and may be exercised as often as occasion therefor shall
occur; and the failure to exercise any such right or remedy shall in no event
be construed as a waiver or release of the same.

                                   9. AGENT

                  9.1.     Appointment.

                           Each Lender hereby appoints CoreStates Bank, N.A.
as agent hereunder, and each Lender hereby authorizes Agent to act hereunder
and under the other instruments and agreements referred to herein (including,
without limitation, the Notes, the Mortgages, and the other Loan Documents) as
its agent hereunder and thereunder. Agent agrees to act as such upon the
express conditions contained in this Article 9 and in the Loan Documents. The
provisions of this Article 9 are solely for the benefit of Lenders; Borrower
shall not have any rights as a third party beneficiary of any of the
provisions hereof except with respect to the provisions requiring Borrower's
consent or that certain matters be satisfactory to Borrower. In performing its
functions and duties under this Agreement, Agent shall act solely as agent of
Lenders and does not assume and shall not be deemed to have assumed any
obligation towards or relationship of agency or trust with or for Borrower.

                  9.2.     Powers; General Immunity.

                           9.2.1.   Duties Specified.

                                    Each Lender irrevocably authorizes Agent
to take such action on such Lender's behalf and to exercise such powers
hereunder and under the other instruments and agreements referred to herein
(including, without limitation, the Loan Documents) as are specifically
delegated to Agent by the terms hereof and thereof, together with such powers
as are reasonably incidental thereto. Agent shall have only those duties and
responsibilities which are expressly specified in this Agreement and the other
Loan Documents and Agent may perform such duties by or through its agents or
employees. The duties of Agent shall be mechanical and administrative in
nature; Agent shall not have by reason of this Agreement a fiduciary
relationship in respect of any Lender; and nothing in this Agreement,
expressed or implied, is intended to or shall be so construed as to impose
upon Agent any obligations in respect of this Agreement or the other
instruments and agreements referred to herein except as expressly set forth
herein or therein. Agent agrees promptly to transmit to Lenders any documents
which have been transmitted by Borrower to Agent for transmittal to Lenders.
Agent shall take such action as has been determined to be taken by a vote of
the applicable Lenders hereunder. In performing its duties and functions under
this Agreement and the Loan Documents, Agent will exercise the same care which
it normally exercises in making and handling loans and handling collateral in
which it alone is interested, but Agent assumes no further responsibility.

                                     (51)


                           9.2.2.   Powers of Agent.

                                    9.2.2.1. In General.

                                    Unless otherwise specifically limited by
this Section 9.2.2, Agent may take all actions hereunder on behalf of all of
the Lenders without seeking the advise or consent of any of the Lenders.

                                    9.2.2.2. Actions Requiring Certain Votes
of Lenders.

                                    Notwithstanding anything to the contrary
herein contained, Agent agrees that it will not, without the unanimous consent
of the Lenders, take any of the following actions whether voluntary or
involuntary pursuant to this Agreement: (i) decrease any of the rates of
interest with respect to the Loan hereunder; (ii) decrease, or postpone the
required date of payment of, any fees with respect to the Loans hereunder;
(iii) reduce the principal of the Loan; (iv) postpone the date fixed for any
payment of principal of or interest on the Loan; (v) change the definitions of
Pro Rata Shares or Requisite Lenders; (vi) amend Section 3.2 (or any defined
terms or financial covenants referenced therein) or this Section 9.2.2.2;
(vii) waive Agent's duty to record the Mortgages when required pursuant to
Section 3.2.1 hereof; (viii) release any collateral for the Loan on terms
other than as specifically provided herein; (ix) increase the Commitment
Amount, or (x) make any Advance after the occurrence of, and during the
continuation of, any Event of Default.

                                    9.2.2.3. Actions Requiring Votes of
Requisite Lenders.

                                    Notwithstanding anything to the contrary
herein contained, Agent agrees that it will not without the vote of the
Requisite Lenders: (i) declare any Event of Default; (ii) exercise any
remedies upon and after the occurrence of an Event of Default; or (iii)
subject to Section 9.2.2.2 hereof, amend or waive any provision of this
Agreement.

                                    9.2.2.4. Agent's Action when Lender Fails
to Respond.

                                    If Agent requests authority to act in a
specified manner, Agent may, at Agent's option, act as if a Lender had
approved such request if such Lender fails or refuses to respond to Agent's
request within seven (7) Business Days after receipt of Agent's written
request.

                           9.2.3.   No Responsibility for Certain Matters.

                                    Agent shall not be responsible to any
Lender for the execution, effectiveness, genuineness, validity,
enforceability, collectibility or sufficiency of this Agreement, the Notes or
the other Loan Documents, or for any representations, warranties, recitals or


                                     (52)


statements made herein or therein or made in any written or oral statement or
in any financial or other statements, instruments, reports, certificates or
any other documents in connection herewith or therewith furnished or made by
Agent to Lenders or by or on behalf of Borrower to Agent or any Lender except
to the extent Agent has actual knowledge to the contrary that such
representation, warranty, recital or statement is false or incorrect, or be
required to ascertain or inquire as to the performance or observance of any of
the terms, conditions, provisions, covenants or agreements contained herein or
therein or as to the use of the proceeds of the Loans or of the existence or
possible existence of any Event of Default or Unmatured Event of Default or
potential Event of Default or Unmatured Event of Default.

                           9.2.4.   Exculpatory Provisions.

                                    Agent and its officers, directors,
employees and agents shall not be liable to any Lender for any action taken or
omitted hereunder or in connection herewith (including, without limitation,
any act or omission under the Notes or the other Loan Documents) unless caused
by its or their gross negligence or willful misconduct. If Agent shall request
instructions from Lenders with respect to any act or action (including the
determination not to take an action) in connection with this Agreement, the
Notes or the other Loan Documents, Agent shall be entitled to refrain from
such act or taking such action unless and until Agent shall have received
instructions from the Requisite Lenders or the applicable percentage of
Lenders, as the case may be. Without prejudice to the generality of the
foregoing, (i) Agent shall be entitled to rely, and shall be fully protected
in relying, upon any communication, instrument or document believed by it to
be genuine and correct and to have been signed or sent by the proper person or
persons, and shall be entitled to rely and shall be protected in relying on
opinions and judgments of attorneys (who may be attorneys for Borrower),
accountants, experts and other professional advisors selected by it with the
approval of Requisite Lenders; and (ii) no Lender shall have any right of
action whatsoever against Agent as a result of Agent's acting or (where so
instructed) refraining from acting under this Agreement, the Notes, or other
Loan Documents in accordance with the instructions of the Requisite Lenders or
the applicable percentage of Lenders, as the case may be. Agent shall be
entitled to refrain from exercising any power, discretion or authority vested
in it under this Agreement, the Notes, or other Loan Documents unless and
until it has obtained the instructions of the Requisite Lenders.

                           9.2.5.   Agent Entitled to Act as Lender.

                                    The agency hereby created shall in no way
impair or affect any of the rights and powers of, or impose any duties or
obligations upon, Agent in its individual capacity as a Lender hereunder. With
respect to its granting of Loans, Agent shall have the same rights and powers
hereunder as any other Lender and may exercise the same as though it were not
performing the duties and functions delegated to it hereunder, and the terms
"Lender" or "Lenders" or any similar term shall, unless the context clearly
otherwise indicates, include Agent in its individual capacity as a Lender.
Notwithstanding the foregoing, Agent shall not be influenced to act hereunder
in a manner inconsistent with the best interests of Lenders by reason of
Agent's involvement in unrelated transactions with Borrower or with any


                                     (53)


Affiliate of Borrower. Agent and its affiliates may accept deposits from, lend
money to and generally engage in any kind of banking, trust, financial
advisory or other business with Borrower or any Affiliate of Borrower as if it
were not performing the duties specified herein, and may accept fees and other
consideration from Borrower or such Affiliate for services in connection with
this Agreement and otherwise without having to account for the same to
Lenders. Lenders acknowledge that Agent has, and may from time to time
hereafter, enter into lending arrangements with Borrower or Affiliates of
Borrower and that Borrower may grant mortgages, security interests or
otherwise encumber its assets in favor of Agent individually and not as agent
for the Lenders as collateral for such lending arrangements, which shall be
independent of the Loan hereunder, provided that Agent shall not, in
connection with any such transaction, encumber any property of Borrower that
would constitute a breach of any of Borrower's covenants under this Agreement.

                           9.2.6.   No Responsibility for Creditworthiness.

                                    Each Lender represents and warrants that
it has made its own independent investigation of the financial condition and
affairs of Borrower and the General Partner in connection with the making of
the Loans hereunder and has made and shall continue to make its own appraisal
of the creditworthiness of Borrower. Agent shall not have any duty or
responsibility, either initially or on a continuing basis, to make any such
investigation or any such appraisal on behalf of Lenders or, except as
expressly provided in this Agreement, to provide any Lender with any credit or
other information with respect thereto whether coming into its possession
before the making of Loans or any time or times thereafter, and Agent shall
further have no responsibility with respect to the accuracy of or the
completeness of the information provided to Lenders.

                                     (54)


                           9.2.7.   Right to Indemnity.

                                    Each Lender severally agrees to indemnify
Agent, its officers, directors, employees and agents, proportionately to its
Pro Rata Share and to the extent Agent shall not have been reimbursed by
Borrower, for and against any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses (including,
without limitation, counsel fees and disbursements) or disbursements of any
kind or nature whatsoever which may be imposed on, incurred by or asserted
against Agent in performing its duties hereunder or in any way relating to or
arising out of this Agreement, except in its capacity as a Lender; provided
that no Lender shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from Agent's gross negligence or willful
misconduct; and provided further that Agent shall not be entitled to be
indemnified hereunder for amounts paid by Agent in settlement of litigation
prior to final judgment unless such settlement shall be consented to by
Requisite Lenders. If any indemnity furnished to Agent for any purpose shall,
in the opinion of Agent, be insufficient or become impaired, Agent may call
for additional indemnity and cease, or not commence, to do the acts
indemnified against (other than acts constituting Agent's obligations to
Lenders hereunder) until such additional indemnity is furnished.

                           9.2.8.   Resignation; Removal; Successor Agent.

                                    9.2.8.1. Agent may resign from the
performance of all its functions and duties hereunder at any time by giving 45
Business Days' prior written notice to Borrower and Lenders. Agent may be
removed at any time with cause by a notice or concurrent notices in writing
delivered to Borrower and Agent and signed by all Lenders other than Agent.
Such resignation or removal shall take effect upon the acceptance by a
successor Agent pursuant to subsections 9.2.8.2 and 9.2.8.3.

                                    9.2.8.2. Upon any such notice of
resignation or removal, Lenders upon the vote of the Requisite Lenders shall
have the right to appoint a successor Agent which shall be a Lender, or such
other Person as is satisfactory to Borrower. Such successor agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring or removed Agent, and the retiring or removed Agent
shall be discharged from all its duties and obligations as Agent under this
Agreement (except as otherwise provided herein).

                                    9.2.8.3. If a successor Agent shall not
have been so appointed within said 45 Business Day period, a resigning (but
not a removed) Agent, with the consent of Borrower, shall then appoint a
successor Agent, which shall be a commercial bank with capital and surplus of
not less than $5,000,000,000 who shall serve as Agent until such time, if any,
as the Requisite Lenders, with the consent of Borrower, appoint a successor
Agent as provided above.

                                     (55)


                                    9.2.8.4. If at the time of Agent's
resignation or removal pursuant to this Section 9.2.8 Agent's Pro-Rata Share
exceeds 33-1/3%, the term "Requisite Lenders," for purposes of this Section
9.2.8 only, shall mean either (i) Lenders whose aggregate Pro Rata Shares
equal or exceed 66.67% or (ii) all Lenders other than Agent.

                  9.3.     Sharing of Recoveries.

                           Lenders hereby agree that all sums recovered (and
the proceeds of all property recovered) from Borrower by any Lender hereunder,
whether as a result of the enforcement of any Mortgage or other Loan Document
or on foreclosure of any banker's or other lien or any setoff or other claim
on or against any deposit or other balance of Borrower held by any Lender,
shall be on behalf of Lenders and shall be shared by Lenders according to
their respective Pro Rata Shares. If a Lender shall make any recovery, it will
promptly remit to the other Lenders their Pro Rata Shares thereof. No Lender's
Pro Rata Share shall have priority over any other Lender's Pro Rata Share.

                  9.4      Ratable Sharing.

                           Each Lender and each subsequent holder by
acceptance of a Note agree among themselves that with respect to all amounts
received by them which are applicable to the payment of or reduction of a
proportion of the aggregate amount of principal and interest due with respect
to the Notes held by the Lender or holder, which is greater than the
proportion received by any other holder of a Note in respect to the aggregate
amount of principal and interest due with respect to the Notes held by it, or
any other amount payable hereunder, that the Lender or holder of a Note
receiving such proportionately greater payments shall notify each other Lender
and the Agent of such receipt and remit to them such amounts as are necessary
so that all such recoveries of principal and interest with respect to the
Notes shall be proportionate to the Lenders' respective Pro Rata Shares. If
any Lender or holder of a Note receiving such proportionately greater payments
is required to return such proportionately greater payment to any trustee,
receiver or other representative of or for Borrower upon or by reason of the
bankruptcy, insolvency, reorganization or dissolution of any entity comprising
Borrower, then such other Lender(s) which received its or their Pro Rata Share
of such proportionately greater payment must also return such amounts to
Borrower as if such payment or payments from the Lender receiving such
proportionately greater payments had not been made.



                               10. MISCELLANEOUS

                  10.1     Integration.

                           This Agreement, the Notes, and the other Loan
Documents shall be construed as one agreement, and in the event of any
inconsistency, the provisions of the Notes shall control over the provision of
this Agreement or any other Loan Document, and the provisions of this


                                     (56)


Agreement shall control over the provisions of any other Loan Document. This
Agreement, the Notes and the other Loan Documents contain all the agreements
of the parties hereto with respect to the subject matter of each thereof and
supersede all prior or contemporaneous discussions and agreements with respect
to such subject matter.

                  10.2.    Modification.

                           Except as provided in Section 9.2.2.2 hereof, and
provided that no modification of Article 9 hereof may be made without Agent's
consent, modifications or amendments of or to the provisions of this
Agreement, Notes, or any other Loan Document shall be effective only if set
forth in a written instrument signed by Requisite Lenders and Borrower. No
Lender shall amend any Note payable to such Lender without the written consent
of Requisite Lenders.

                  10.3.    Waivers.

                           Except as provided in Section 9.2.2.2 hereof, any
provision of this Agreement, the Notes or any other Loan Document may be
waived if, but only if, such waiver is in writing and is signed by the
Borrower and Requisite Lenders.

                  10.4     Notices.

                           Except as hereinelsewhere specifically allowed with
respect to a Notice of Borrowing or a Notice of Rate Election, any notice or
other communication by one party hereto to the other shall be in writing and

                  10.5.    Survival.

                           The terms of this Agreement and all agreements,
representations, warranties and covenants made by Borrower in any other Loan
Document shall survive the issuance and payment of the Notes and shall
continue as long as any portion of the Indebtedness shall remain outstanding
and unpaid; provided, however, that the covenants set forth in Sections 2.2.7,
6.2, 10.8, and 10.9 hereof shall survive the payment of the Indebtedness.
Borrower hereby acknowledges that Lenders have relied upon the foregoing in
making the Loans.

                  10.6.    Closing.

                           Closing hereunder shall occur on or before October
15, 1997 at the offices of Mesirov Gelman Jaffe Cramer & Jamieson, 1735 Market

time and place as the parties hereto may determine. In the event Closing is
not held on or before October 15, 1997, unless extended by all of the parties
hereto, the rights and obligations of the parties hereto contained herein
shall be terminated and be of no further force or effect except for the
provisions of Sections 6.2, 10.8, and 10.9.

                                     (59)


                  10.7.    Successors and Assigns; Governing Law.

                           This Agreement shall be binding upon and inure to
the benefit of the respective successors and assigns of the parties hereto;
provided, however (i) that Borrower shall not assign this Agreement, or any
rights or duties arising hereunder, without the express prior written consent
of all Lenders and (ii) no Lender may assign its rights or duties arising
hereunder or enter into any participation arrangement other than as permitted
by Section 10.10 hereof without the express prior written consent of Borrower.
This Agreement shall be construed and enforced in accordance with the internal
laws of the Commonwealth of Pennsylvania for contracts made and to be
performed in Pennsylvania.

                  10.8.    Jurisdiction.

                           IN ANY LEGAL PROCEEDING INVOLVING, DIRECTLY OR
INDIRECTLY, ANY MATTER ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE
RELATIONSHIP EVIDENCED HEREBY, BORROWER HEREBY IRREVOCABLY SUBMITS TO THE
NONEXCLUSIVE JURISDICTION OF ANY STATE OR FEDERAL COURT LOCATED IN ANY COUNTY
IN THE COMMONWEALTH OF PENNSYLVANIA WHERE AGENT MAINTAINS AN OFFICE AND AGREES
NOT TO RAISE ANY OBJECTION TO SUCH JURISDICTION OR TO THE LAYING OR
MAINTAINING OF THE VENUE OF ANY SUCH PROCEEDING IN SUCH COUNTY. BORROWER
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
BORROWER.

                  10.9.    Waiver of Jury Trial.

                           BORROWER, AGENT AND EACH LENDER HEREBY WAIVE TRIAL
BY JURY IN ANY LEGAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER
(WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF OR
RELATED TO THIS AGREEMENT OR THE RELATIONSHIPS EVIDENCED HEREBY. THIS
PROVISION IS A MATERIAL INDUCEMENT FOR LENDERS TO ENTER INTO, ACCEPT OR RELY
UPON THIS AGREEMENT.

                  10.10.   Assignment by Lenders; Participation.

                           10.10.1 Each Lender may, with the consent of
Borrower that shall not unreasonably be withheld, delayed or conditioned,
assign, or enter into participation arrangements with respect to, portions of
such Lender's interest in this Agreement, the Facility and the Note and other
Loan Documents evidencing or securing such Lender's interest, provided that


                                     (60)


each Lender shall retain in its own name and not subject to participation an
interest in the Facility that is not less than the greater of (i) fifty-one
percent (51%) of such Lender's Pro Rata Share as of the date hereof or (ii)
$10,000,000. Assignees shall succeed to and assume all of the rights and
obligations hereunder; Lenders entering into participation arrangements shall
include in such arrangements that no such participant shall have any right to
consent to or approve matters hereunder except that such participation
arrangements may grant to the participant the right to approve (i) any
decrease in the rates of interest payable by Borrower with respect to the
Loans, (ii) any change of the final maturity of the Loans that is not
otherwise provided herein, and (iii) any change in the Commitment Amount.

                           10.10.2. Concurrently with any assignment by a
Lender pursuant to Section 10.10.1 hereof, the assigning Lender shall deliver
to Agent and Borrower a copy of the assignment instrument and shall pay to
Agent an assignment fee of $3,500. Borrower, upon request of Agent, shall
promptly execute and deliver to Agent replacement Notes, reflecting the
then-current Pro Rata Shares of each Lender, including the assignee Lender,
which replacement Notes shall be delivered to each Lender upon surrender to
Agent of Borrower's prior Note in favor of such Lender. Promptly after receipt
of each of such prior Notes, Agent shall mark the same "Replaced" and return
it to Borrower.

                  10.11.   Conflicts Between Instruments.

                           In the event of any conflict between the provisions
of this Agreement and the provisions of any Note or any other Loan Document
(including, without limitation any provisions with respect to the delivery of
notice of default and the granting of any opportunity to cure) the provisions
of this Agreement shall prevail, notwithstanding any provision in any other
document to the effect that such other document shall be deemed controlling,
except that the provisions of the Notes shall control over the provisions of
this Agreement. Any Event of Default by Borrower hereunder shall, after the
granting of such notice and expiration of any grace period as may be herein
contained, constitute an event of default under the Notes and the Mortgages,
without regard for any requirement for notice or opportunity to cure contained
in the Notes or the Mortgages.

                  10.12.   Excess Payments.

                           If Borrower shall pay any interest under the terms
of the Notes at a rate higher than the maximum rate allowed by applicable law,
then such excess payment shall be credited against outstanding Advances as
directed by Borrower unless Borrower notifies Lenders in writing to return the
excess payment to Borrower. Notwithstanding anything to the contrary contained
in this Agreement, crediting the excess payments hereunder as a payment of
principal shall not trigger the application of any prepayment penalties that
might otherwise apply to a prepayment of principal hereunder.

                  10.13.   Partial Invalidity.

                                     (61)


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

                  10.14.   Compliance with Rules.

                           Lenders shall not be required by operation or
effect of any provision of this Agreement to violate any statute or regulation
under state or federal law, including all Rules.

                  10.15.   Headings.

                           The heading of any Article or Section contained in
this Agreement is for convenience of reference only and shall not be deemed to
amplify, limit, modify or give full notice of the provisions thereof.

                  10.16.   Counterparts.

                           This Agreement may be signed in counterparts each
of which shall be deemed to be an original and all of which together shall
constitute one and the same agreement.

                  10.17.   Retention of Documents.

                           Unless otherwise provided herein, any documents,
schedules, or other papers delivered to Agent on behalf of Lenders or to any
Lender may be destroyed or otherwise disposed of by Agent or such Lender six
months after they are delivered to or received by Agent or such Lender, unless
Borrower requests the return of such documents, schedules, invoices or other
papers and makes arrangements, at Borrower's expense, for their return.

                  10.18.   Time of the Essence.

                           Time is the essence of this Agreement and of each
of the Loan Documents.

                  10.19.   Future Development Loans.

                           The parties contemplate that Borrower shall, from
time to time prior to the Termination Date, deliver to Agent requests to
provide construction financing for projects to be undertaken by Borrower, by a
Venture, or by an entity in which Borrower, directly or indirectly, has a
substantial interest. Agent shall review such requests in its absolute
discretion, and in no event shall Agent be required to approve any such
request. If Agent does approve a request for such construction financing and
the owner and developer of the project is either Borrower, a wholly-owned
subsidiary of Borrower or a Venture in which Borrower, directly of indirectly,


                                     (62)


is the managing partner or has the ability control the placing of such
construction financing, Agent shall present such request to each of the
Lenders, all of which shall have the right, but not the obligation, to be part
of the lending group for such loan. If the proposed developer of the project
that is the subject of the financing request is not Borrower or an entity
described in the preceding sentence, the request may be presented by Agent to
fewer than all of Lenders, as Borrower may determine. If any Lender to which
Agent presents a financing request pursuant to this Section determines not to
participate in the lending group, Agent may, with the consent of Borrower not
to be unreasonably withheld, include in such lending group financial
institutions that are not a Lender. Nothing in this Section shall obligate any
Lender to provide credit to Borrower or any other Person, other than the
Facility.

                  10.20.   Name of General Partner.

                           The name and designation Pennsylvania Real Estate
Investment Trust is the designation of the Trustees from time to time under
the Trust Agreement as amended

                                     (63)



and restated as of September 29, 1997 and all persons dealing with the
Pennsylvania Real Estate Investment Trust must look solely to the Trust
property for the enforcement of any claims against the Pennsylvania Real
Estate Investment Trust, as neither the Trustees, officers, agents or
shareholders of the Pennsylvania Real Estate Investment Trust assume any
personal liability for obligations entered into by the Pennsylvania Real
Estate Investment Trust by reason of their status as said Trustee, officer,
agent or shareholder.

                  10.21.   Counterpart Execution.

                           This Agreement may be executed in multiple
counterparts, and when each of the named parties hereto has executed such
counterpart copies hereof, such shall constitute a single agreement among such
parties.

         IN WITNESS WHEREOF, Borrower, Agent and Lenders have executed this
Agreement under seal, intending to be legally bound hereby, as of the day and
year first above written.
