         NOW, THEREFORE, in consideration of the terms and conditions contained
herein, and of any extensions of credit now or hereafter made to or for the
benefit of Borrower by Bank, the parties hereto, intending to be legally bound
hereby, agree as follows:

1. THE LINE; USE OF PROCEEDS.

         1.1 Line of Credit. Bank will establish for Borrower for and during the
period from the date hereof and until April 21, 2001 (the "Expiration Date"),
subject to the terms and conditions hereof (including without limitation the
Borrowing Base set forth in Section 1.4 herein), a revolving line of credit (the
"Line") pursuant to which Bank will from time to time make loans to Borrower in
an aggregate outstanding principal amount not to exceed at any time Twenty
Million Dollars ($20,000,000). Within the limits of the Line, Borrower may
borrow, repay and reborrow under the Line. The Line shall be subject to all
terms and conditions set forth in all of the Loan Documents which terms and
conditions are incorporated herein. Borrower's obligation to repay advances
under the Line shall be evidenced by Borrower's promissory note (the "Line
Note") in the face amount of Twenty Million Dollars ($20,000,000), dated the
date of this Agreement, payable to the order of Bank, and otherwise in form and
substance satisfactory to Bank.

         1.2 Use of Proceeds. Borrower agrees to use advances under the Line (i)
to acquire commercial real estate or an interest therein, (ii) to fund loans
secured by commercial real estate, (iii) to purchase loans secured by commercial
real estate, or an interest therein, and (iv) to reduce indebtedness secured by
senior liens on property which Borrower owns or holds a loan or an interest in a
loan, and for no other purpose (including without limitation, the payment of
distributions or dividends to partners or shareholders of RAIT or RAIT, LP, as
the case may be, or for working capital).

         1.3 Advances of the Line. Borrower shall give Bank not less than 3
Business Days prior written notice of a proposed advance of the Line (each a
"Line Request"). Each Line Request shall (i) state the use of the proceeds of
the Line being requested (including the real estate project to which such use
relates), (ii) contain a description of the economics of such real estate
project, and (iii) contain such other information as Bank may request in the
exercise of its reasonable discretion. Provided that all of the conditions
precedent to Bank making such advance have occurred, and provided further that
the making of such advance will not cause Borrower to be in default of the
covenants and conditions set forth in this Agreement (including without
limitation Sections 7.1 and 7.2 herein), Bank shall make the proceeds of

                                      -6-
<PAGE>

such advance available to Borrower by crediting the amount thereof to RAIT, LP's
deposit account with Bank.

         1.4 Borrowing Base. Notwithstanding anything contained herein to the
contrary, but subject to the provisions of Section 4.4(b) herein, the aggregate
outstanding principal balance of the Line shall not exceed at any time forty
percent (40%) of the Appraised Value of the Real Estate ("Borrowing Base").
Borrower shall from time to time repay an aggregate amount of principal of the
Line Note equal to the amount, if any by which the aggregate then unpaid
principal balance of the Line Note exceeds the limits stated in the previous
sentence.

2. INTEREST RATE.

         2.1 Interest on the Line. Interest on the unpaid outstanding principal
balance of the Line will accrue from the date of advance until final payment
thereof at a per annum rate equal to the Prime Rate in effect from time to time
(such interest rate to change immediately upon any change in the Prime Rate).

         2.2 Default Interest. From the maturity of the obligations evidenced by
the Line Note, as well as upon the occurrence of an Event of Default, the
outstanding principal balance and all other sums due hereunder and under the
Line Note shall bear interest at a rate which is four percent (4%) in excess of
the non-default rate otherwise set forth herein ("Default Rate").
Notwithstanding the provisions of 42 Pa. C.S. ss. 8101 to the contrary, the
Default Rate shall apply to all sums evidenced by the Line Note as set forth
above, including after entry of a judgment or judgments against Borrower, and
said judgment or judgments shall bear interest at the Default Rate until
satisfied in full.

         2.3 Calculation. Interest will be computed on the basis of a year of
360 days and paid for the actual number of days elapsed.

         2.4 Limitation of Interest to Maximum Lawful Rate. In no event will the
rate of interest payable hereunder exceed the maximum rate of interest permitted
to be charged by applicable law (including the choice of law rules) and any
interest paid in excess of the permitted rate will be refunded to Borrower. Such
refund will be made by application of the excessive amount of interest paid
against any sums outstanding hereunder and will be applied in such order as Bank
may determine. If the excessive amount of interest paid exceeds the sums
outstanding, the portion exceeding the sums outstanding will be refunded in cash
by Bank. Any such crediting or refunding will not cure or waive any default by
Borrower. Borrower agrees, however, that in determining whether or not any
interest payable hereunder exceeds the highest rate permitted by law, any
non-principal payment, including without limitation prepayment fees and late
charges, will be deemed to the extent permitted by law to be an expense, fee,
premium or penalty rather than interest.

                                      -7-

<PAGE>

3. PAYMENTS AND FEES.

         3.1 Interest Payments on the Line. Borrower will pay interest on the
outstanding principal balance of the Line monthly, on the first day of each
calendar month commencing on May 1, 1999.

         3.2 Principal Payments on the Line. Borrower will pay the outstanding
principal balance of the Line, together with any accrued and unpaid interest
thereon, and any other sums due pursuant to the terms hereof, on the Expiration
Date.

         3.3 Commitment Fee. Borrower shall pay to Bank a commitment fee of Two
Hundred Thousand Dollars ($200,000) to be paid upon the execution of this
Agreement.

         3.4 Late Charge. In the event that Borrower fails to pay any
principal, interest or other fees or expenses payable hereunder for a period of
at least ten (10) days after the same shall become due, in addition to paying
such sums, Borrower will pay to Bank a late charge equal to four percent (4%),
of such past due payment as compensation for the expenses incident to such past
due payment.

         3.5 Payment Method. Borrower irrevocably authorizes Bank to debit all
payments required to be made by Borrower hereunder or otherwise under the Line,
on the date due, from any deposit account maintained by Borrower with Bank
(other than escrow funds owned legally by Borrower but held in escrow for the
beneficial interest of another Person). Otherwise, Borrower will be obligated to
make such payments directly to Bank. All payments are to be made in immediately
available funds. If Bank accepts payment in any other form, such payment shall
not be deemed to have been made until the funds comprising such payment have
actually been received by or made available to Bank.

         3.6 Application of Payments. Prior to the occurrence of an Event of
Default, any and all payments on account of the Line will be applied for, to any
amounts due to Bank pursuant to the Loan Documents, other than principal and
interest on the Line; second, to accrued interest due under the Line; and third,
to outstanding principal under the Line. Following the occurrence of an Event of
Default, any and all payments on account of the Line will be applied to accrued
and unpaid interest, outstanding principal and other sums due hereunder or under
the Loan Documents, in such order as Bank, in its discretion, elects. If
Borrower makes a payment or payments and such payment or payments, or any part
thereof, are subsequently invalidated, declared to be fraudulent or
preferential, set aside or are required to be repaid to a trustee, receiver, or
any other person under any bankruptcy act, state or federal law, common law or
equitable cause, then to the extent of such payment or payments, the obligations
or part thereof hereunder intended to be satisfied shall be revived and
continued in full force and effect as if said payment or payments had not been
made.

                                      -8-
<PAGE>

         3.7 Loan Account. Bank will open and maintain on its books a loan
account with respect to advances made, repayments, prepayments, the computation
and payment of interest and fees and the computation and final payment of all
other amounts due and sums paid to Bank under this Agreement. Except in the case
of manifest error in computation, such account will be conclusive and binding on
the Borrower as to the amount at any time due to Bank from Borrower under this
Agreement or the Note.

         3.8 Indemnity; Loss of Margin. Borrower will indemnify Bank against any
loss or expense which Bank sustains or incurs as a consequence of an Event of
Default, including, without limitation, any failure of Borrower to pay when due
(at maturity, by acceleration or otherwise) any principal, interest, fee or any
other amount due under this Agreement or the other Loan Documents. If Bank
sustains or incurs any such loss or expense it will from time to time notify
Borrower in writing of the amount determined in good faith by the Bank to be
necessary to indemnify Bank for the loss or expense. Such amount will be due and
payable by Borrower to Bank within ten (10) days after presentation by Bank of a
statement setting forth a brief explanation of and Bank's calculation of such
amount, which statement shall be conclusively deemed correct absent manifest
error. Any amount payable to the Bank under this Section will bear interest at
the default rate payable under the Line from the due date until paid, both
before and after judgment.

         In the event that any present or future law, rule, regulation, treaty
or official directive or the interpretation or application thereof by any
central bank, monetary authority or governmental authority, or the compliance
with any guideline or request of any central bank, monetary authority or
governmental authority (whether or not having the force of law):

                  (a) subjects Bank to any tax with respect to any amounts
payable under this Agreement or the other Loan Documents by Borrower or
otherwise with respect to the transactions contemplated under this Agreement or
the other Loan Documents (except for taxes on the overall net income and/or
revenues of Bank imposed by the United States of America, the Commonwealth of
Pennsylvania, or any political subdivision of either of them); or

                  (b) imposes, modifies or deems applicable any deposit
insurance, reserve, special deposit, capital maintenance, capital adequacy, or
similar requirement against assets held by, or deposits in or for the account
of, or loans or advances or commitment to make loans or advances by, the Bank;
or

                  (c) imposes upon Bank any other condition with respect to
advances or extensions of credit or the commitment to make advances or
extensions of credit under this Agreement,

and the result of any of the foregoing is to increase the costs of Bank, reduce
the income receivable by or return on equity of Bank or impose any expense upon
Bank with respect to

                                      -9-
<PAGE>


any advances or extensions of credit or commitments to make advances or
extensions of credit under this Agreement, Bank shall so notify Borrower in
writing. Borrower agrees to pay Bank the amount of such increase in cost,
reduction in income, reduced return on equity or capital, or additional expense
within ten (10) days after presentation by Bank of a statement concerning such
increase in cost, reduction in income, reduced return on equity or capital, or
additional expense. Such statement shall set forth a brief explanation of the
amount and Bank's calculation of the amount (in determining such amount the Bank
may use any reasonable averaging and attribution methods), which statement shall
be conclusively deemed correct absent manifest error. If the amount set forth in
such statement is not paid within ten (10) days after such presentation of such
statement, interest will be payable on the unpaid amount at the default rate
payable under the Line from the due date until paid, both before and after
judgment.

         3.9 Extension of Expiration Date. On or before May 21 of each year
commencing on May 21, 2000, Bank will notify Borrower that (i) it has elected to
extend the Expiration Date then in effect by twelve (12) months, or (ii) it will
not extend the Expiration Date then in effect. A failure by Bank to send any
such notice shall be deemed to be an election by Bank not to extend the
Expiration Date then in effect. In the event Bank determines in the exercise of
its sole discretion that it will extend the Expiration Date then in effect,
Borrower shall, at least five (5) days prior to the then current Expiration Date
pay to Bank an extension fee of One Hundred Thousand Dollars ($100,000). If
Borrower shall fail to pay such extension fee to Bank as and when required,
Bank's election to extend the Expiration Date shall be deemed to be canceled and
shall be null and void and of no further force or effect and the Expiration Date
then in effect shall continue as if Bank had not provided any notice of election
to extend.

         4.3 Covenants Regarding Collateral. So long as the Line Note remains

consent of Bank, which consent shall not be unreasonably withheld or delayed:

                  (a) Borrower shall not obtain any other loans or other
financing secured by an encumbrance, lien, mortgage, security interest or other
interest in any of the Collateral, or assign, sell, transfer (voluntarily or by

                  (b) Borrower shall receive or collect monthly (or otherwise if
so provided by the terms of the Collateral Documents) payment of principal and
interest pursuant to and in accordance with the terms and conditions of the
Collateral Documents.

                  (c) Prior to the occurrence of an Event or Default, Borrower
shall not alter, amend, extend, cancel or otherwise change any terms or
conditions of the Collateral Documents if as a result thereof there would occur
an Event of Default or Potential Default. Following the occurrence of an Event
of Default, Borrower shall not alter, amend, cancel or otherwise change any
provision of the Collateral Documents.

                  (d) In the event Borrower goes into possession of any of the
Real Estate, should Bank thereafter decide to go into possession pursuant to
this Agreement, Borrower shall immediately vacate the affected Real Estate and
perform whatever acts or execute whatever documents required by Bank, in its
sole discretion, to expedite Bank's possession of the affected Real Estate.

                  (e) Borrower shall keep accurate and complete records of
Payments and the Collateral Documents and shall furnish Bank with such
information as Bank may request, including without limitations, the information
required by Section 8 herein.

                  (f) Following the occurrence of an Event of Default Borrower,

<PAGE>


surrender of any Collateral Document; or (iii) solicit or accept any prepayment
of monies under any Collateral Document.

                  (h) Borrower shall not release or terminate any of its
interest in, to or under any Collateral Document.

                  (i) Borrower shall not propose or consent to any plan of

         4.4 Default Under Collateral Documents.

                  (a) Borrower shall give Bank written notice of the occurrence
of an event of default or a default under the terms of any Collateral Document
("Collateral Document Default") within five (5) Business Days after becoming
aware of a Collateral Document Default, specifying the loan to which such
Collateral Document Default relates, the nature of the Collateral Document
Default, and such other information as Bank may request. Notwithstanding the
provisions of Section 12.1(p) herein, provided that Bank receives evidence
satisfactory to it that, notwithstanding a Collateral Document Default, (i)
Borrower remains in compliance with the covenants set forth in Sections 7.1 and
7.2 herein, and (ii) Borrower maintains a Debt Service Coverage Ratio of not
less than 3.0 to 1, such Collateral Document Default shall not constitute an
Event of Default hereunder.

                  (b) Following the occurrence and during the continuation of
any Collateral Document Default, (i) Borrower will provide Bank with such
information relating thereto and to the Collateral Documents and Real Estate to
which such Collateral Document Default relates as Bank may request, and (ii)
Bank may at any time declare that the Real Estate to which such Collateral
Document Default relates has become ineligible for the purposes of calculating
the Borrowing Base and that the fair market value of such Real Estate shall no
longer constitute a portion of the Appraised Value for the purposes of
calculating the Borrowing Base. In the event of any such declaration by Bank,
Borrower shall, within ninety (90) days thereafter, but subject to the
immediately following sentence, either (x) repay the outstanding principal
amount of the Line in an amount equal to the amount by which the then unpaid
principal balance of the Line exceeds the Borrowing Base (after taking into
account the exclusion of the Appraised Value of such Real Estate), or (y) in
lieu of such repayment, deliver to Bank Substitute Collateral where the
Appraised Value of the Real Estate to which such Substitute Collateral relates,
when added to the Appraised Value of all other Real Estate then constituting
eligible Collateral, will cause the then outstanding principal balance of the
Line to be in compliance with the Borrowing Base. Any such delivery of
Substitute Collateral shall be accompanied by all such financing statement
amendments and other documents and instruments as Bank may require to reflect
its security interest in and to the Substitute Collateral (including without
limitation appropriate amendments to Exhibits "A" and "B"

                                      -13-


<PAGE>


hereto). Notwithstanding the foregoing to the contrary, if the applicable
Obligor cures the Collateral Document Default to the satisfaction of Bank within
such ninety (90) - day period, the Appraised Value of the Real Estate to which
such Collateral Document Default relates shall once again be included for the
purposes of calculating the Borrowing Base and Borrower shall not be required to
make any repayment of the Line or to deliver Substitute Collateral to Bank with
respect to such Collateral Document Default.

         4.5 Release of Collateral. Borrower shall provide Bank with at least
ten (10) Business Days prior written notice of any proposed repayment in full of
any Collateral Documents in connection with which the Collateral Documents will
be released, or of any other requested release of the Collateral Documents, to
the extent Borrower shall receive the same and otherwise as much prior written
notice as is possible. Provided that Borrower shall either (x) repay the
outstanding principal amount of the Line in an amount equal to the amount by
which the then unpaid principal balance of the Line exceeds the Borrowing Base
(after taking into account the exclusion of the Appraised Value of the Real
Estate to which such release will relate), or (y) in lieu of such repayment,
deliver to Bank Substitute Collateral where the Appraised Value of the Real
Estate to which such Substitute Collateral relates, when added to the Appraised
Value of all other Real Estate that will remain following such release, will
cause the then outstanding principal balance of the Line to be in compliance
with the Borrowing Base, Bank shall, upon receipt of such repayment or
Substitute Collateral, release its lien on the applicable Collateral Documents.

         4.6 Power of Attorney. Borrower does hereby appoint and constitute Bank
as Borrower's true and lawful attorney, irrevocably, such appointment to be
coupled with an interest, with full power (in the name of borrower or
otherwise), (a) to ask, require, demand, receive, compound and give acquittance
for any and all Payments due and to become due under or arising out of any
Collateral Document to which Borrower is or may be come entitled, (b) to enforce
compliance by any Obligor with all of the terms and provisions of any Collateral
Document, (c) to endorse any checks or other instruments or orders in connection
therewith, and (d) to file any claims or take any action or institute any
proceedings which Bank may deem to be necessary or advisable in the premises.

         4.7 Collateral Document Remedies. Upon the occurrence of an Event of
Default, Bank shall have, but shall not be limited to, the following rights, in
addition to the rights accorded by the Uniform Commercial Code, as amended from
time to time, and at law or in equity, each of which may be exercised at any
time:

                  (a) to declare by written notice to Borrower that Borrower's
interest in the Collateral Documents shall terminate and be of no further force
or effect, that Bank shall have all right, title and interest in and to the
Collateral Documents, and that Bank shall have the sole right to exercise any
and all rights and remedies provided in or arising out of the Collateral
Documents;

                                      -14-

all Collateral Documents to Bank, together with all other information relating
to the Collateral Documents, the Real Estate, or the loans pertaining thereto,
as Borrower shall maintain (including without limitation accounting records).

                  (c) to transfer all or any part of the Collateral Documents
into the name of Bank or its nominee;

                  (d) to demand and be entitled to (by notice to the Obligors or
any management company or trustee holding and/or collecting the same) all
Payments;

                  (e) to release any or all Collateral Documents;

                  (f) to endorse any Collateral Documents or the proceeds
thereof in the name of Borrower;

                  (g) to sell all or any part of the Collateral Documents upon
any exchange or at public or private sale, at Bank's option, at any time or
times, following advertisement in the generally accepted manner for material of
the same type as the Collateral, upon five (5) days prior written notice of the
time of any private sale or the time and place of any public sale, and, at any
such sale, Bank or its nominee shall have the right to become the purchaser
thereof;

                  (h) to accept in settlement for any Collateral Document a sum
less than the face value without notice to Borrower;

                  (i) to demand and be entitled to all rents under all leases or
rental agreements with respect to any Real Estate, to the extent permitted by
the Collateral Documents; and/or

                  (j) to do any and all acts, including, but not limited to,
executing, signing, acknowledging, sealing and delivering any agreement,
contract, modification, rescission, note, deed, check, receipt, conveyancing
instrument, release, discharge, or document of any kind whatsoever in the name,
place and stead of Borrower, as attorney in fact, in furtherance of the remedies
afforded Bank herein, under the Uniform Commercial Code, as amended from time to
time, at law or in equity. Borrower agrees that the rights and powers specified
above are irrevocable and coupled with an interest.

         4.8 Cumulative Remedies. All rights and remedies granted herein or in
the Collateral Documents or otherwise available to Bank shall be cumulative and
concurrent and may be pursued singly, successively, or together at Bank's sole
option, and may be exercised from time to time and as often as occasion therefor
shall occur until the Line and all other

                                      -15-

<PAGE>


amounts due hereunder, are paid in full; and the failure to exercise any such
right or remedy shall in no event be construed as a waiver or release of same by
Bank. Bank may resort to any security it holds in such order and manner as Bank
sees fit.

         4.8 Nonlimitation of Bank's Rights under Note and Collateral Documents.
Nothing contained herein shall prejudice or be construed to prejudice the right
of Bank to commence and prosecute, or to prevent Bank from commencing and
prosecuting, any action which it may deem advisable or which it may be entitled
to commence and prosecute for the foreclosure of the Note and the Collateral
Documents and any of them, or to prejudice any other rights of Bank.

         4.9 Nonassumption of Liability by Bank. Bank does not by the execution
and acceptance of this Agreement or by making demand or collecting monies under
the Note, the Collateral Documents or any lease or rental agreement with respect
to any of the Real Estate, assume any liability or become liable in any manner
whatsoever for the performance of any of the terms and conditions thereof,
unless and until Bank shall expressly assume such obligations by a writing to
the Obligors instructing them to make Payments directly to Bank, it being
understood and agreed that notice to such Obligors to make Payments to a lockbox
shall not be deemed to be such an express assumption; nor shall Bank be liable
for any act, offsets or defenses which Borrower or any such Obligor may have
against each other. Nothing contained in this Section 4.9 shall be deemed to
relieve Bank from any obligations arising out of its gross negligence or wilful
misconduct.

         4.10 Bank's Discretion. The Collateral Documents shall be dealt with
and enforced by Bank in its sole discretion. In the course of its administration
of the Collateral Documents, Bank may, without notice to Borrower, use its
discretion with respect to the exercising, or refraining from, any rights or
actions which may be vested in it or which it may be entitled to take or assert
under law or by agreement with Borrower or otherwise.

         4.11 Release. Bank shall not be liable to Borrower for any action taken
or omitted or for errors in judgment. Bank does not assume or warrant and shall
have no responsibility or liability (express or implied) for the collectability,
enforceability, genuineness or validity of the Collateral Documents; or the
financial condition or legal status of any Obligor.

         4.12 General. The above-described security interests, assignments, and
liens shall not be rendered void by the fact that no Bank Indebtedness exists as
of any particular date, but shall continue in full force and effect until the
Bank Indebtedness has been repaid, Bank has no agreement or commitment
outstanding pursuant to which Bank may extend credit to or on behalf of Borrower
and Bank has executed termination statements or releases with respect thereto.
IT IS THE EXPRESS INTENT OF THE BORROWER THAT ALL OF THE COLLATERAL SHALL SECURE
NOT ONLY THE OBLIGATIONS UNDER THE

                                      -16-

LOAN DOCUMENTS, BUT ALSO ALL OTHER PRESENT AND FUTURE OBLIGATIONS OF BORROWER
TO BANK.

         4.13 Additional Documents and Future Actions. Borrower will, at its

advisable to perfect, protect, maintain or enforce the security interests in the
Collateral, to permit Bank to protect or enforce its interest in the Collateral,
or to carry out the terms of the Loan Documents. Each Borrower hereby authorizes
and appoints Bank as its attorney-in-fact, with full power of substitution, to
take such actions as Bank may deem advisable to protect the Collateral and its
interests thereon and its rights hereunder, to execute on Borrower's behalf and
file at Borrower's expense financing statements and assignments, and amendments
thereto, in those public offices deemed necessary or appropriate by Bank to
establish, maintain and protect a continuously perfected security interest in
the Collateral, and to execute on that Obligor's behalf such other documents and
notices as Bank may deem advisable to protect the Collateral and its interests
therein and its rights hereunder. Such power being coupled with an interest is

financing statement and agrees that such filing is sufficient as a financing
statement.

arising will become immediately due and payable without any further demand or
notice;

receive no further extensions of credit thereunder;

         If an Event of Default occurs under Section 12.1(e) or (f), all Bank
Indebtedness shall become immediately due and payable.

         12.3 Sale or Other Disposition of Collateral. The sale or other
disposition of the Collateral, or any part thereof, by Bank after an Event of
Default may be for cash, credit or any combination thereof, and Bank may
purchase all or any part of the Collateral at public or, if permitted by law,
private sale, and in lieu of actual payment of such purchase price, may set-off
the amount of such purchase price against the Bank Indebtedness then owing. Any
sales of the Collateral may be adjourned from time to time with or without
notice. Bank shall have the right to conduct such sales at Borrower's premises,
at Borrower's expense, or elsewhere, on such occasion or occasions as Bank may
see fit. Any notice required to be given by Bank of a sale or other disposition
or other intended action by Bank with respect to any of the Collateral which is
deposited in the United States mail, postage prepaid and duly addressed to
Borrower at the address specified in Section 13.1 below, at least five (5)
business days prior to such proposed action, shall constitute fair and
reasonable notice to Borrower of any such action. The net proceeds realized by
Bank upon any such sale or other disposition, after deduction for the expenses
of holding, preparing for sale, selling or otherwise disposing of the Collateral
incurred by Bank in connection therewith and all other costs and expenses
related thereto including attorney fees, shall be applied in such order as Bank,
in its sole discretion, elects, toward satisfaction of the Bank Indebtedness.
Bank shall account to Borrower for any surplus realized upon such sale or other
disposition, and Borrower shall remain liable for any deficiency. The
commencement of any action, legal or equitable, or the rendering of any judgment
or decree for any deficiency shall not affect Bank's security interest in the
Collateral. Borrower agrees that Bank has no obligation to preserve rights to
the

                                      -36-

<PAGE>


Collateral against any other parties. Bank shall be under no obligation to
marshall any assets in favor of Borrower or any other party or against or in
payment of any or all of the Bank Indebtedness.

         12.4 Set-Off. Without limiting the rights of Bank under applicable law,
Bank has and may exercise a right of set-off, a lien against and a security
interest in all property of Borrower now or at any time in Bank's possession in
any capacity whatsoever, including but not limited to any balance of any
deposit, trust or agency account, or any other bank account with Bank, as
security for all Bank Indebtedness. At any time and from time to time following
the occurrence of an Event of Default or a Potential Default, or Bank may
without notice or demand, set off and apply any and all deposits (general or
special, time or demand, provisional or final) at any time held and other
indebtedness at any time owing by Bank to or for the credit of Borrower against
any or all of the Bank Indebtedness and Borrower's obligations under the Loan
Documents.

         If any bank account of Borrower with Bank is attached or otherwise
liened or levied upon by any third party, Bank need not await the running of any
applicable grace period hereunder, but Bank shall have and be deemed to have the
immediate right of set-off and may apply the funds or amount thus set-off
against Borrower's obligations to the Bank.

         12.5 Delay or Omission Not Waiver. Neither the failure nor any delay on
the part of Bank to exercise any right, remedy, power or privilege under the
Loan Documents upon the occurrence of any Event of Default or otherwise shall
operate as a waiver thereof or impair any such right, remedy, power or
privilege. No waiver of any Event of Default shall affect any later Event of
Default or shall impair any rights of Bank. No single, partial or full exercise
of any rights, remedies, powers and privileges by the Bank shall preclude
further or other exercise thereof. No course of dealing between Bank and
Borrower shall operate as or be deemed to constitute a waiver of Bank's rights
under the Loan Documents or affect the duties or obligations of Borrower.

         12.6 Remedies Cumulative; Consents. The rights, remedies, powers and
privileges provided for herein shall not be deemed exclusive, but shall be
cumulative and shall be in addition to all other rights, remedies, powers and
privileges in Bank's favor at law or in equity. Whenever the Bank's consent or
approval is required or permitted, such consent or approval shall be at the sole
and absolute discretion of Bank.

         12.7 Certain Fees, Costs, Expenses and Expenditures. Borrower agrees
to pay on demand all costs and expenses of Bank, including without limitation:

                  (a) all costs and expenses in connection with the preparation,
review, negotiation, execution, delivery and administration of the Loan
Documents, and the other documents to be delivered in connection therewith, or
any amendments, extensions and

                                      -37-


<PAGE>


increases to any of the foregoing (including, without limitation, attorney's
fees and expenses, and the cost of appraisals and reappraisals of Collateral),
and the cost of periodic lien searches and tax clearance certificates, as Bank
deems advisable;

                  (b) all losses, costs and expenses in connection with the
enforcement, protection and preservation of the Bank's rights or remedies under
the Loan Documents, or any other agreement relating to any Bank Indebtedness, or
in connection with legal advice relating to the rights or responsibilities of
Bank (including without limitation court costs, attorney's fees and expenses of
accountants and appraisers); and

                  (c) any and all stamp and other taxes payable or determined to
be payable in connection with the execution and delivery of the Loan Documents,
and all liabilities to which Bank may become subject as the result of delay in
paying or omission to pay such taxes.

         In the event Borrower shall fail to pay taxes, insurance, assessments,
costs or expenses which it is required to pay hereunder, or fails to keep the
Collateral free from security interests or lien (except as expressly permitted
herein), or fails to maintain or repair the Collateral as required hereby, or
otherwise breaches any obligations under the Loan Documents, Bank in its
discretion, may make expenditures for such purposes and the amount so expended
(including attorney's fees and expenses, filing fees and other charges) shall be
payable by Borrower on demand and shall constitute part of the Bank
Indebtedness.

         With respect to any amount required to be paid by Borrower under this
Section, in the event Borrower fails to pay such amount on demand, Borrower
shall also pay to Bank interest thereon at the Default Rate. Borrower's
obligations under this Section shall survive termination of this Agreement.

         12.8 Time is of the Essence. Time is of the essence in Borrower's
performance of their obligations under the Loan Documents.

13. COMMUNICATIONS AND NOTICES.

         13.1 Communications and Notices. All notices, requests and other

brokerage fee or commission in connection with this transaction. Whether any
such claim is made against Bank by any broker, finder or agent or any other
Person, Borrower agrees to indemnify, defend and hold Bank harmless against any
such claim, at Borrower's own cost and expense, including Bank's attorneys'
fees. Borrower further agrees that until any such claim or demand is adjudicated
in Bank's favor, the amount claimed and/or demanded shall be deemed part of the
Bank Indebtedness secured by the Collateral.

         16.2 No Joint Venture. Nothing contained herein is intended to permit

Agreement be construed as creating a partnership, joint venture or making Bank
an investor in Borrower.

warranties made by Borrower in the Loan Documents or made by or on its behalf in
connection with the transactions contemplated here shall be true at all times

the making by Bank of the loam or advances to Borrower. All

                                      -41-

statements contained in any certificate, statement or other document delivered
by or on behalf of Borrower pursuant hereto or in connection with the
transactions contemplated hereunder shall be deemed representations and
warranties by Borrower.

hereby will bind and inure to the benefit of the parties hereto and their
respective permitted successors and assigns.

party.

delivered in the Commonwealth of Pennsylvania and will be construed in
accordance with and governed by the laws of such Commonwealth.

         16.12 Integration. The Loan Documents shall be construed as integrated
and complementary of each other, and as augmenting and not restricting Bank's
rights, powers, remedies and security. The Loan Documents contain the entire
understanding of the parties thereto with respect to the matters contained
therein and supercede all prior agreements and understandings between the
parties with respect to the subject matter thereof and do not require parol or
extrinsic evidence in order to reflect the intent of the parties. In the event
of

                                      -42-

         16.16 Waiver of Right to Trial by Jury. BORROWER AND BANK WAIVE ANY
RIGHT TO TRIAL BY JURY ON ANY CLAIM, DEMAND, ACTION OR CAUSE OF ACTION (a)
