         (ii)     the balance toward the reduction of the principal sum;

and the balance of the principal sum and all interest thereon shall be due and
payable on the tenth day of April, 2008 (the "Maturity Date"). Interest on the

         The term "Applicable Interest Rate" as used in the Security Instrument

<PAGE>


                       ARTICLE 3. DEFAULT AND ACCELERATION


         (a) The whole of the principal sum of this Note, (b) interest, default
interest, late charges and other sums, as provided in this Note, the Security
Instrument or the Other Security Documents (defined below), (c) all other
monies agreed or provided to be paid by Borrower in this Note, the Security
Instrument or the Other Security Documents, (d) all sums advanced pursuant to
the Security Instrument to protect and preserve the Property (defined below)
and the lien and the security interest created thereby, and (e) all sums
advanced and costs and expenses incurred by Lender in connection with the Debt
(defined below) or any part thereof, any renewal, extension, or change of or
substitution for the Debt or any part thereof, or the acquisition or perfection
of the security therefor, whether made or incurred at the request of Borrower
or Lender (all the sums referred to in (a) through (e) above shall collectively
be referred to as the "Debt") shall without notice become immediately due and
payable at the option of Lender if any payment required in this Note is not
paid on or prior to the date when due or on the Maturity Date or on the
happening of any other default, after the expiration of any applicable notice
and grace periods, herein or under the terms of the Security Instrument or any
of the Other Security Documents (collectively, an "Event of Default").

                          ARTICLE 4. DEFAULT INTEREST

         Borrower does hereby agree that upon the occurrence of an Event of
Default, Lender shall be entitled to receive and Borrower shall pay interest on
the entire unpaid principal sum at a rate equal to the lesser of (a) five
percent (5%) plus the Applicable Interest Rate and (b) the maximum interest
rate which Borrower may by law pay (the "Default Rate"). The Default Rate shall
be computed from the occurrence of the Event of Default until the earlier of
the date upon which the Event of Default is cured or the date upon which the
Debt is paid in full. Interest calculated at the Default Rate shall be added to
the Debt, and shall be deemed secured by the Security Instrument. This clause,
however, shall not be construed as an agreement or privilege to extend the date
of the payment of the Debt, nor as a waiver of any other right or remedy
accruing to Lender by reason of the occurrence of any Event of Default.

                             ARTICLE 5. PREPAYMENT

         (a) The principal balance of this Note may not be prepaid in whole or
in part prior to the fourth Loan Year (defined below). During the fourth Loan
Year or any time thereafter, the principal balance of this Note may be prepaid
in whole, but not in part, upon not less than thirty (30) days and not more
than forty (40) days prior written notice to Lender specifying the date on
which prepayment is to be made (the "Prepayment Date") and upon payment of:

         (i)      all accrued interest to and including the Prepayment Date;

         (ii)     all interest which would have accrued on the principal
                  balance of this Note after the Prepayment Date to and
                  including the next succeeding ninth day of a calendar month
                  following the Prepayment Date (the "Interest Shortfall


                                      -2-

<PAGE>



                  Payment"), if such prepayment occurs on a date which is not
                  the tenth day of a month;

         (iii)    all other sums due under this Note, the Security Instrument
                  and all Other Security Documents; and

         (iv)     a prepayment consideration (the "Prepayment Consideration")
                  in an amount equal to the present value as of the Prepayment
                  Date of the Calculated Payments (defined below) from the
                  Prepayment Date through the Maturity Date determined by
                  discounting such payments at the Discount Rate (defined
                  below).


Notwithstanding anything to the contrary herein, provided no Event of Default
exists under this Note, the Security Instrument or the Other Security
Documents, in the event of any prepayment which occurs during the three (3)
months prior to the Maturity Date, no Prepayment Consideration shall be due in
connection therewith, but Borrower shall be required to pay all other sums due
hereunder, including, without limitation, the Interest Shortfall Payment, if
any.

         (b) The "Calculated Payments" are monthly payments of interest only
which would be due based on the principal amount outstanding on the Prepayment
Date and assuming an interest rate per annum equal to the difference (if such
difference is greater than zero) between (i) the Applicable Interest Rate minus
(ii) the Treasury Rate (defined below). The "Discount Rate" is the rate which,
when compounded monthly, is equivalent to the Treasury Rate (defined below)
when compounded semi-annually. The "Treasury Rate" is the yield calculated by
the linear interpolation of the yields, as reported in the Federal Reserve
Statistical Release H.15-Selected Interest Rates under the heading U.S.
Government Securities/Treasury constant maturities for the week ending prior to
the Prepayment Date, of the U.S. Treasury constant maturities with maturity
dates (one longer and one shorter) most nearly approximating the Maturity Date.
In the event Release H.15 is no longer published, Lender shall select a
comparable publication to determine the Treasury Rate. Lender shall notify
Borrower of the amount and the basis of determination of the required
Prepayment Consideration which shall be conclusive and binding on Borrower
absent manifest error. "Loan Year" as used in this Note shall mean each 365 or
366, as applicable, day period commencing on the next succeeding tenth day of a
calendar month after the date of this Note (or the date of this Note if it is
dated the tenth day of a calendar month).

         (c) If any notice of prepayment is given under this Article 5, the
principal balance of this Note and the other sums required under this
prepayment section shall be due and payable on the Prepayment Date. Lender
shall not be obligated to accept any prepayment of the principal balance of
this Note unless it is accompanied by all sums due in connection therewith.
Notwithstanding anything contained in this Article 5 to the contrary, provided
no Event of Default exists, no Prepayment Consideration shall be due in
connection with a complete or partial prepayment resulting from the application
of insurance proceeds or condemnation awards pursuant to Sections 3.3 and 3.6
of the Security Instrument, but Borrower shall be required to pay all other
sums due hereunder, including, without limitation, the Interest Shortfall
Payment, if applicable.

<PAGE>


         (d) If a Default Prepayment (defined below) occurs, Borrower shall pay
to Lender the entire Debt, including, without limitation, the following
amounts:

         (i)      if the Default Prepayment occurs prior to the time when
                  prepayment of the principal balance of this Note is
                  permitted, an amount equal to the sum of (A) the present
                  value of the interest payments which would have accrued on
                  the principal balance of this Note (outstanding as of the
                  date of such Default Prepayment) at the Applicable Interest
                  Rate from the date of such Default Prepayment to the first
                  day prepayment is permitted pursuant to this Note discounted
                  at a rate equal to the Treasury Rate except that such
                  Treasury Rate shall be based on the U.S. Treasury constant
                  maturity most nearly approximating the date upon which
                  prepayment is first permitted pursuant to this Note, and (B)
                  an amount equal to the greater of (1) one percent (1%) of
                  the principal balance of this Note outstanding on the date of
                  such Default Prepayment, and (2) the present value as of the
                  first day of the fourth Loan Year of the Calculated Payments
                  based on the Treasury Rate in effect at the time of such
                  Default Prepayment from the first day of the fourth Loan Year
                  through the Maturity Date determined by discounting such
                  payments at the Discount Rate; and

         (ii)     if the Default Prepayment occurs at a time when prepayment of
                  the principal balance of this Note is permitted, the
                  Prepayment Consideration and the Interest Shortfall Payment,
                  if applicable.

For purposes of this Note, the term "Default Prepayment" shall mean a prepayment
of the principal amount of this Note made after the occurrence of any Event of
Default or an acceleration of the Maturity Date under any circumstances,
including, without limitation, a prepayment occurring in connection with
reinstatement of the Security Instrument provided by statute under foreclosure
proceedings or exercise of a power of sale, any statutory right of redemption
exercised by Borrower or any other party having a statutory right to redeem or
prevent foreclosure, any sale in foreclosure or under exercise of a power of
sale or otherwise.

                              ARTICLE 6. SECURITY

         This Note is secured by the Security Instrument and the Other Security
Documents. The term "Security Instrument" as used in this Note shall mean the
mortgage and security agreement dated the date hereof in the principal sum of
$12,000,000 given by Borrower to (or for the benefit of) Lender covering the
fee estate and a contemplated leasehold estate as described in Article 24 of
the Security Instrument of Borrower in certain premises located in Philadelphia
County, Commonwealth of Pennsylvania, and other property, as more particularly
described therein (collectively, the "Property") and intended to be duly
recorded in said County. The term "Other Security Documents" as used in this
Note shall mean all and any of the documents other than this Note or the
Security Instrument now or hereafter executed by Borrower and/or others and by
or in favor of Lender, which wholly or partially secure or guarantee payment of
this Note. Whenever used, the singular number shall include the plural, the
plural number shall include the


                                      -4-
<PAGE>




singular, and the words "Lender" and "Borrower" shall include their respective
successors, assigns, heirs, executors and administrators.

         All of the terms, covenants and conditions contained in the Security
Instrument and the Other Security Documents are hereby made part of this Note
to the same extent and with the same force as if they were fully set forth
herein.

                           ARTICLE 7. SAVINGS CLAUSE

         This Note is subject to the express condition that at no time shall
Borrower be obligated or required to pay interest on the principal balance due
hereunder at a rate which could subject Lender to either civil or criminal
liability as a result of being in excess of the maximum interest rate which
Borrower is permitted by applicable law to contract or agree to pay. If by the
terms of this Note, Borrower is at any time required or obligated to pay
interest on the principal balance due hereunder at a rate in excess of such
maximum rate, the Applicable Interest Rate or the Default Rate, as the case may
be, shall be deemed to be immediately reduced to such maximum rate and all
previous payments in excess of the maximum rate shall be deemed to have been
payments in reduction of principal and not on account of the interest due
hereunder. All sums paid or agreed to be paid to Lender for the use,
forbearance, or detention of the Debt, shall, to the extent permitted by
applicable law, be amortized, prorated, allocated, and spread throughout the
full stated term of the Note until payment in full so that the rate or amount
of interest on account of the Debt does not exceed the maximum lawful rate of
interest from time to time in effect and applicable to the Debt for so long as
the Debt is outstanding.

                            ARTICLE 8. LATE CHARGE

         If any sum payable under this Note is not paid on or prior to the date
on which it is due, Borrower shall pay to Lender upon demand an amount equal to
the lesser of five percent (5%) of the unpaid sum or the maximum amount
permitted by applicable law to defray the expenses incurred by Lender in
handling and processing the delinquent payment and to compensate Lender for the
loss of the use of the delinquent payment and the amount shall be secured by
the Security Instrument and the Other Security Documents.

                           ARTICLE 9. NO ORAL CHANGE

         This Note may not be modified, amended, waived, extended, changed,
discharged or terminated orally or by any act or failure to act on the part of
Borrower or Lender, but only by an agreement in writing signed by the party
against whom enforcement of any modification, amendment, waiver, extension,
change, discharge or termination is sought.

                    ARTICLE 10. JOINT AND SEVERAL LIABILITY

         If Borrower consists of more than one person or party, the obligations
and liabilities of each person or party shall be joint and several.

                              ARTICLE 11. WAIVERS

         Borrower and all others who may become liable for the payment of all
or any part of the Debt do hereby severally waive presentment and demand for
payment, notice of dishonor, protest and notice of protest and non-payment and
all other notices of any kind. No release of any security for the Debt or
extension of time for payment of this Note or any installment hereof, and no
alteration, amendment or waiver of any provision of this Note, the Security
Instrument or the Other Security Documents made by agreement between Lender or
any other person or party shall release, modify, amend, waive, extend, change,
discharge, terminate or affect the liability of Borrower, and any other person
or entity who may become liable for the payment of all or any part of the Debt,
under this Note, the Security Instrument or the Other Security Documents. No
notice to or demand on Borrower shall be deemed to be a waiver of the
obligation of Borrower or of the right of Lender to take further action without
further notice or demand as provided for in this Note, the Security Instrument
or the Other Security Documents. If Borrower is a partnership, the agreements
contained herein shall remain in full force and effect, notwithstanding any
changes in the individuals or entities comprising the partnership, and the term
"Borrower," as used herein, shall include any alternate or successor
partnership, but any predecessor partnership and its partners shall not thereby
be released from any liability. If Borrower is a corporation, the agreements
contained herein shall remain in full force and effect notwithstanding any
changes in the shareholders comprising, or the officers and directors relating
to, the corporation, and the term "Borrower" as used herein, shall include any
alternate or successor corporation, but any predecessor corporation shall not
be relieved of liability hereunder. If Borrower is a limited liability company,
the agreements herein contained shall remain in full force and effect,
notwithstanding any changes in the individuals or entities comprising the
limited liability company and the term "Borrower," as used herein, shall
include any alternate or successor limited liability company, but any
predecessor limited liability company and its members shall not be released
from any liability. (Nothing in the foregoing sentence shall be construed as a
consent to, or a waiver of, any prohibition or restriction on transfers of
interests in such partnership, corporation or limited liability company which
may be set forth in the Security Instrument or any Other Security Document.)

                             ARTICLE 12. TRANSFER

         Upon the transfer of this Note, Borrower hereby waiving notice of any
such transfer, Lender may deliver all the collateral mortgaged, granted,
pledged or assigned pursuant to the Security Instrument and the Other Security
Documents, or any part thereof, to the transferee who shall thereupon become
vested with all the rights herein or under applicable law given to Lender with
respect thereto, and Lender shall thereafter forever be relieved and fully
discharged from any liability or responsibility in the matter; but Lender shall
retain all rights hereby given to it with respect to any liabilities and the
collateral not so transferred.

                      ARTICLE 13. WAIVER OF TRIAL BY JURY

         BORROWER HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, THE
RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM, WHETHER IN
CONTRACT, TORT OR OTHERWISE, RELATING DIRECTLY OR INDIRECTLY TO THE LOAN
EVIDENCED BY THIS NOTE, THE APPLICATION FOR THE LOAN EVIDENCED BY THIS NOTE,
THIS NOTE, THE SECURITY INSTRUMENT OR THE OTHER SECURITY DOCUMENTS OR ANY ACTS
OR OMISSIONS OF LENDER, ITS OFFICERS, EMPLOYEES, DIRECTORS OR AGENTS IN
CONNECTION THEREWITH.

                            ARTICLE 14. EXCULPATION

        (a) Except as otherwise provided herein, in the Security Instrument or
in the Other Security Documents, Lender shall not enforce the liability and
obligation of Borrower to perform and observe the obligations contained in this
Note or the Security Instrument by any action or proceeding wherein a money
judgment shall be sought against Borrower, except that Lender may bring a
foreclosure action, action for specific performance or other appropriate action
or proceeding to enable Lender to enforce and realize upon this Note, the
Security Instrument, the Other Security Documents, and the interest in the
Property, the Rents (as defined in the Security Instrument) and any other
collateral given to Lender created by this Note, the Security Instrument and the
Other Security Documents; provided, however, that any judgment in any such
action or proceeding shall be enforceable against Borrower only to the extent of
Borrower's interest in the Property, in the Rents and in any other collateral
given to Lender. Lender, by accepting this Note and the Security Instrument,
agrees that it shall not, except as otherwise provided in Section 11.10 of the
Security Instrument, sue for, seek or demand any deficiency judgment against
Borrower in any such action or proceeding, under or by reason of or under or in
connection with this Note, the Other Security Documents or the Security
Instrument. The provisions of this Section shall not, however, (i) constitute a
waiver, release or impairment of any obligation evidenced or secured by this
Note, the Other Security Documents or the Security Instrument; (ii) impair the
right of Lender to name Borrower as a party defendant in any action or suit for
judicial foreclosure and sale under the Security Instrument; (iii) affect the
validity or enforceability of any indemnity, guaranty, master lease or similar
instrument made in connection with this Note, the Security Instrument, or the
Other Security Documents; (iv) impair the right of Lender to obtain the
appointment of a receiver; (v) impair the enforcement of the Assignment of
Leases and Rents executed in connection herewith; or (vi) impair the right of
Lender to enforce the provisions of Sections 11.10, 13.2, 13.3 and 13.4 of the
Security Instrument.

         (b) Notwithstanding the provisions of this Article 14 to the contrary,
Borrower shall be personally liable to Lender for the Losses (as defined in the
Security Instrument) it incurs due to: (i) fraud or intentional
misrepresentation by Borrower or any other person or entity in connection with
the execution and the delivery of this Note, the Security Instrument or the
Other Security Documents; (ii) Borrower's misapplication or misappropriation of
Rents received by Borrower after the occurrence of an Event of Default; (iii)
Borrower's misapplication or misappropriation of tenant security deposits or
Rents collected in advance; (iv) the misapplication


                                      -7-
<PAGE>

or the misappropriation of insurance proceeds or condemnation awards; (v)
Borrower's failure to pay Taxes (as defined in the Security Instrument), Other
Charges (as defined in the Security Instrument) (except to the extent that sums
sufficient to pay such amounts have been deposited in escrow with Lender
pursuant to the terms of the Security Instrument), charges for labor or
materials or other charges that can create liens on the Property (unless bonded
pursuant to the terms of the Security Instrument); (vi) Borrower's failure to
return or to reimburse Lender for all Personal Property (as defined in the
Security Instrument) taken from the Property by or on behalf of Borrower and
not replaced with Personal Property of the same utility and of the same or
greater value; (vii) any act of actual waste or arson by Borrower, any
principal, affiliate, member or general partner thereof or by any Indemnitor
(as defined in the Security Instrument) or Guarantor (as defined in the
Security Instrument); (viii) any fees or commissions paid by Borrower to any
principal, affiliate, member or general partner of Borrower, Indemnitor or
Guarantor in violation of the terms of this Note, the Security Instrument or
the Other Security Documents; or (ix) Borrower's failure to comply with the
provisions of Sections 4.2, 7.1, 12.1 and 12.2 of the Security Instrument.

         (c) Notwithstanding the foregoing, the agreement of Lender not to
pursue recourse liability as set forth in Subsection (a) above SHALL BECOME
NULL AND VOID and shall be of no further force and effect in the event of
Borrower's default under Sections 3.11 (for ten (10) days after notice by
Lender), 4.3 or 8.1, 8.2, 8.3 or 8.4 of the Security Instrument, or in the
event of Principal's (as defined in the Security Instrument) default under
Section 4.3 of the Security Instrument or if the Property or any part thereof
shall become an asset in (i) a voluntary bankruptcy or insolvency proceeding,
or (ii) an involuntary bankruptcy or insolvency proceeding which is not
dismissed within ninety (90) days of filing.

         (d) Nothing herein shall be deemed to be a waiver of any right which
Lender may have under Section 506(a), 506(b), 1111(b) or any other provision
of the U.S. Bankruptcy Code to file a claim for the full amount of the
indebtedness secured by the Security Instrument or to require that all
collateral shall continue to secure all of the indebtedness owing to Lender in
accordance with this Note, the Security Instrument and the Other Security
Documents.

                             ARTICLE 15. AUTHORITY

         Borrower (and the undersigned representative of Borrower, if any)
represents that Borrower has full power, authority and legal right to execute
and deliver this Note, the Security Instrument and the Other Security Documents
and that this Note, the Security Instrument and the Other Security Documents

construed, applied and enforced in accordance with the laws of the State of New

                         ARTICLE 17. SERVICE OF PROCESS

         (a) (i) Borrower will maintain a place of business or an agent for
service of process in New York, New York and give prompt notice to Lender of
the address of such place of business and of the name and address of any new
agent appointed by it, as appropriate. Borrower further agrees that the failure
of its agent for service of process to give it notice of any service of process
will not impair or affect the validity of such service or of any judgment based
thereon. If, despite the foregoing, there is for any reason no agent for
service of process of Borrower available to be served, and if it at that time
has no place of business in New York, New York, then Borrower irrevocably
consents to service of process by registered or certified mail, postage
prepaid, to it at its address given in or pursuant to the first paragraph
hereof.

                  (ii) Borrower initially and irrevocably designates Wachtel &
Masyr, LLP, with offices on the date hereof at 110 East 59th Street, New York,
New York 10022, to receive for and on behalf of Borrower service of process in
New York, New York with respect to this Note.

         (b) With respect to any claim or action arising hereunder or under the
Security Instrument or the Other Security Documents, Borrower (a) irrevocably
submits to the nonexclusive jurisdiction of the courts of the State of New York
and the United States District Court located in the Borough of Manhattan in New
York, New York, and appellate courts from any thereof, and (b) irrevocably
waives any objection which it may have at any time to the laying on venue of
any suit, action or proceeding arising out of or relating to this Note brought
in any such court, irrevocably waives any claim that any such suit, action or
proceeding brought in any such court has been brought in an inconvenient forum.

          (c) Nothing in this Note will be deemed to preclude Lender from
 bringing an action or proceeding with respect hereto in any other
 jurisdiction.

                            ARTICLE 18. COUNSEL FEES

          In the event that it should become necessary to employ counsel to
 collect the Debt or to protect or foreclose the security therefor, Borrower
 also agrees to pay all reasonable fees and expenses of Lender, including,
 without limitation, reasonable attorney's fees for the services of such
 counsel whether or not suit be brought.

                              ARTICLE 19. NOTICES
