                                1. PAYMENT TERMS

         Principal and interest due under this Note shall be paid as follows:

                  (a)      A payment of interest only on the date hereof for the
period from the date hereof through September 30, 1999, both inclusive;

                  (b)      A constant payment of $14,034.35, on the first day of
November, 1999 and on the first day of each calendar month thereafter, up to and
including the first day of September, 2009; and

                  (c)      On the Anticipated Repayment Date and on the first
day of each calendar month thereafter until this Note is paid in full, in the
manner set forth in Section 18 of this Note;

with payments under this Note to be applied pursuant to the provisions of
Section 18 of this Note, or if the provisions of Section 18 of this Note are not
yet effective, as follows:

                           (i)      First, to the payment of interest and other
         costs and charges due in connection with this Note or the Debt, as
         Lender may determine in its sole discretion; and

                           (ii)     The balance shall be applied toward the
         reduction of the principal sum;

                                                   MORGAN GUARANTY TRUST COMPANY

<PAGE>

and on the first day of October, 2009 (the "Maturity Date" or the "Anticipated
Repayment Date"), the entire outstanding principal balance hereof, together with
all accrued but unpaid interest thereon, shall be due and payable in full,
provided, however, that in the event such amounts are not paid in full on such
date, the Maturity Date shall be extended to the first day of October, 2029 (the
"Extended Maturity Date"). Interest on the principal sum of this Note shall be
calculated on the basis of a three hundred sixty (360) day year and paid for the
actual number of days elapsed. All amounts due under this Note shall be payable
without setoff, counterclaim or any ether deduction whatsoever.

                                   2. INTEREST

         The term "Applicable Interest Rate" as used in this Note shall mean (a)
from the date of this Note through but not including the Anticipated Repayment
Date, a rate per annum equal to Eight and Seven One Hundredths Percent (8.07%)
(the "Initial Interest Rate"), and (b) from and after the Anticipated Repayment
Date through and including the date this Note is paid in full, a rate per annum
equal to the greater of (i) the Initial Interest Rate plus two percent (2.0%),
or (ii) the Treasury Index (as hereinafter defined) plus two and one-tenth
percent (2.1%) plus two percent (2%) ((i) or (ii), as applicable, the "Revised
Interest Rate"). The term "Treasury Index" for purposes of this Section 2 means
the yield calculated by the linear interpolation of the yields, as reported in
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 Anticipated Repayment Date, of U.S. Treasury constant
maturities with maturity dates (one longer and one shorter) most nearly
approximating ten (10) years after the Anticipated Repayment Date. (In the event
Release H.I5 is no longer published, Lender shall select a comparable
publication to determine the Treasury Rate.)

                                   3. SECURITY

         This Note is secured by, and Lender is entitled to the benefits of, the
Security Instrument, the Assignment, the Environmental Agreement, and the other
Loan Documents (hereinafter defined). The term "Security Instrument" means the
Deed of Trust and Security Agreement dated the date hereof given by Borrower for
the use and benefit of Lender covering the estate of Borrower in certain
premises as more particularly described therein (which premises, together with
all properties, rights, titles, estates and interests now or hereafter securing
the Debt and/or other obligations of Borrower under the Loan Documents, are
collectively referred to herein as the "Property"). The term "Assignment" means
the Assignment of Leases and Rents of even date herewith executed by Borrower in
favor of Lender. The term "Environmental Agreement" means the Environmental
Indemnity Agreement of even date herewith executed by Borrower in favor of
Lender. The term "Escrow Agreement" means the Escrow Agreement for Reserves and
Impounds of even date herewith executed by Borrower in favor of Lender. The term
"Loan Documents" refers collectively to this Note, the Security Instrument, the
Assignment, the Environmental Agreement, the Escrow Agreement and any and all
other documents executed in connection with this Note or 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 or pertains to indebtedness
evidenced by this Note.

                                   4. LATE FEE

         If any installment payable under this Note is not received by Lender
within ten (10) days after the date on which it is due (without regard to any
applicable cure and/or notice period), Borrower shall pay to Lender upon demand
an amount equal to the lesser of (a) five percent (5%) of such unpaid sum or (b)
the maximum amount permitted by applicable law to defray the expenses incurred
by Lender in handling and processing such delinquent payment and to compensate
Lender for the loss of the use of such delinquent payment, and such amount shall
be secured by the Loan Documents.

                           5. DEFAULT AND ACCELERATION

         So long as an Event of Default exists, Lender may, at its option,
without notice or demand to Borrower, declare the Debt immediately due and
payable. All remedies hereunder, under the Loan Documents and at law or in
equity shall be cumulative. In the event that it should become necessary to
employ counsel to collect the Debt or to protect or foreclose the security for
the Debt or to defend against any claims asserted by Borrower arising from or
related to the Loan Documents, Borrower also agrees to pay to Lender on demand
all costs of collection or defense incurred by Lender, including reasonable
attorneys' fees for the services of counsel whether or not suit be brought.

                               6. DEFAULT INTEREST

         Upon the occurrence of an Event of Default Borrower shall pay interest
on the entire unpaid principal sum and any other amounts due under the Loan
Documents at the rate equal to the lesser of (a) the maximum rate permitted by
applicable law, or (b) the greater of (i) five percent (5%) above the Applicable
Interest Rate or (ii) five percent (5%) above the Prime Rate (hereinafter
defined), in effect at the time of the occurrence of the Event of Default (the
"Default Rate"). The term "Prime Rate" means the prime rate reported in the
Money Rates section of The Wall Street Journal. In the event that The Wall
Street Journal should cease or temporarily interrupt publication, the term
"Prime Rate" shall mean the daily average prime rate published in another
business newspaper, or business section of a newspaper, of national standing and
general circulation chosen by Lender. In the event that a prime rate is no
longer generally published or is limited, regulated or administered by a
governmental or quasi-governmental body, then Lender shall select a comparable
interest rate index which is readily available and verifiable to Borrower but is
beyond Lender's control. The Default Rate shall be computed from the occurrence
of the Event of Default until the actual receipt and collection of a sum of
money determined by Lender to be sufficient to cure the Event of Default.
Amounts of interest accrued at the Default Rate shall constitute a portion of
the Debt, and shall be deemed secured by the Loan Documents. 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.

                                  7. PREPAYMENT

                  (a)      The principal balance of this Note may not be prepaid
in whole or in part (except with respect to the application of casualty or
condemnation proceeds) prior to the Maturity Date. If following the occurrence
of any Event of Default, Borrower shall tender payment to Lender or Lender shall
receive proceeds (whether through foreclosure or the exercise of the other
remedies available to Lender under the Security Instrument or the other Loan
Documents), Borrower shall pay in addition to interest accrued and unpaid on the
principal balance of this Note and all other sums then due under this Note and
the other Loan Documents a prepayment consideration in an amount equal to the
greater of (A) one percent (1%) of the outstanding principal balance of this
Note at the time such payment or proceeds are received, or (B) (x) the present
value as of the date such payment or proceeds are received of the remaining
scheduled payments of principal and interest from the date such payment or
proceeds are received through the Maturity Date (including any balloon payment)
determined by discounting such payments at the Discount Rate (as hereinafter
defined), less (y) the amount of the payment or proceeds received. The term
"Discount Rate" means the rate which, when compounded monthly, is equivalent to
the Treasury Rate (as hereinafter defined), when compounded semi-annually. The
term "Treasury Rate" means the yield calculated by the linear interpolation of
the yields, as reported in 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 date the payment or such proceeds
are received, of 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 except in the case of manifest error. Notwithstanding
the foregoing, Borrower shall have the additional privilege to prepay the entire
principal balance of this Note (together with any other sums constituting the
Debt) on any scheduled payment date occurring on or after that date which is
three (3) months preceding the Maturity Date without any fee or consideration
for such privilege.

                  (b)      If the prepayment results from the application to the
Debt of the casualty or condemnation proceeds from the Property, no prepayment
consideration will be imposed. Partial prepayments of principal resulting from
the application of casualty or condemnation proceeds to the Debt shall not
change the amounts of subsequent monthly installments nor change the dates on
which such installments are due, unless Lender shall otherwise agree in writing.

                  (c)      (i)      Notwithstanding any provision of this
Section 7 to the contrary, at any time during which voluntary prepayment of this
Note is prohibited by Section 7(a) hereof and after the earlier of (1) the date
which is two (2) years after the "startup day," within the meaning of Section
860G(a)(9) of the Internal Revenue Code of 1986, as amended from time to time or
any successor statute (the "Code"), of a "real estate mortgage investment
conduit," within the meaning of Section 860D of the Code, that holds this Note,
and (2) a regularly scheduled payment date on or after that date which is four
(4) years after the date of this Note, and provided no Event of Default (or any
event which with the passage of time or the giving of notice, or both,

                                                   MORGAN GUARANTY TRUST COMPANY

under any of the Loan Documents, Borrower may cause the release of the Property
(in whole but not in part) from the lien, terms and conditions (including
without limitation the assignment of leases) of the Security Instrument and the
other Loan Documents other than this Note upon the satisfaction of the following
conditions precedent:

         date (the "Release Date") on which the Defeasance Deposit (hereinafter
         defined) is to be made;

                                    (B)      the payment to Lender of interest

         including the Release Date;

                                    (C)      the payment to Lender of all other
         sums, not including scheduled interest or principal payments, due under
         this Note, the Security Instrument and the other Loan Documents;

                                    (D)      the payment to Lender of the

                                    (E)      the delivery to Lender of:

                                             (1)      a security agreement, in
                                    form and substance satisfactory to Lender,
                                    creating a first priority lien on the

                                    "Security Agreement");

                                             (2)      a release of the Property
                                    from the lien of the Security Instrument
                                    (for execution by Lender) in a form
                                    appropriate for the jurisdiction in which
                                    the Property is located;

                                    set forth in this subparagraph (i) have been
                                    satisfied;

                                    a perfected first priority security interest
                                    in the Defeasance Deposit and the U.S.
                                    Obligations purchased by Lender on behalf of
                                    Borrower;

                                    adequate to provide payment on or prior to,
                                    but as close as possible to, all successive

                                             (7)      payment of all of Lender's
                                    expenses incurred in connection with the

                                    documents or instruments as Lender may

         In connection with the conditions set forth in subsection (c)(i)(E)
above, Borrower hereby appoints Lender as its agent and attorney-in-fact for the
purpose of using the Defeasance Deposit to purchase U.S. Obligations which
provide payment on or prior to, but as close as possible to, all successive
scheduled payment dates after the Release Date upon which interest and principal
payments are required under this Note (including the amounts due on the Maturity
Date) and in amounts equal to the scheduled payments due on such dates under
this Note (the "Scheduled Defeasance Payments"). Borrower, pursuant to the
Security Agreement or other appropriate document, shall authorize and direct
that the payments received from the U.S. Obligations may be made directly to
Lender and applied to satisfy the obligations of the Borrower under this Note.

         (ii)     Upon compliance with the requirements of this subsection (c),
the Property shall be released from the lien of the Security Instrument and the
pledged U.S. Obligations shall be the sole source of collateral securing this
Note. Any portion of the Defeasance Deposit in excess of the amount necessary to
purchase the U.S. Obligations required by subparagraph (c)(i) above and satisfy
the Borrower's obligations under this subsection (c) shall be remitted to the
Borrower with the release of the Property from the lien of the Security
Instrument.

         (iii)    For purposes of this subsection (c), the following terms shall
have the following meanings:

                           (A)      The term "Defeasance Deposit" shall mean an
                  amount equal to 100% of the remaining principal amount of this
                  Note, the Yield Maintenance Premium, any costs and expenses
                  incurred or to be incurred in the purchase of the U.S.
                  Obligations necessary to meet the Scheduled Defeasance
                  Payments and any revenue, documentary stamp or intangible
                  taxes or any other tax or charge due in connection with the
                  transfer of this Note or otherwise required to accomplish the
                  agreements of this subsection;

                           (B)      The term "Yield Maintenance Premium" shall
                  mean the amount (if any) which, when added to the remaining
                  principal amount of this Note, will be sufficient to purchase
                  U.S. Obligations providing the required Scheduled Defeasance
                  Payments; and

                           (C)      The term "U.S. Obligations" shall mean
                  direct non-callable obligations of the United States of
                  America.

                  (iv)     Upon the release of the Property in accordance with
this subsection (c), Borrower shall, at Lender's request, assign all its
obligations and rights under this Note, together with the pledged Defeasance
Deposit, to a successor special purpose entity designated by Borrower and
approved by Lender in its sole discretion. Such successor entity shall execute
an assumption agreement in form and substance satisfactory to Lender in its sole
discretion pursuant to which it shall assume Borrower's obligations under this
Note and the Security Agreement. In connection with such assignment and
assumption, Borrower shall (x) deliver to Lender an opinion of counsel in form
and substance and delivered by counsel satisfactory to Lender in its sole
discretion stating, among other things, that such assumption agreement is
enforceable against Borrower and such successor entity in accordance with its
terms and that this Note, the Security Agreement and the other Loan Documents,
as so assumed, are enforceable against such successor entity in accordance with
their respective terms, and (y) pay all costs and expenses incurred by Lender or
its agents in connection with such assignment and assumption (including, without
limitation, the review of the proposed transferee and the preparation of the
assumption agreement and related documentation). In connection with such
assignment and assumption, Borrower and any Guarantor may be released of
personal liability under the Note and the other Loan Documents, but only as to
acts or events occurring after the closing of such assignment and assumption.

                  (v)      Upon the release of the Property in accordance with
this subsection (c), Borrower shall have no further right to prepay this Note
pursuant to the other provisions of this Section 7 or otherwise.

                                8. 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 this 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. Notwithstanding
anything to the contrary contained herein or in any of the other Loan Documents,
it is not the intention of Lender to accelerate the maturity of any interest
that has not accrued at the time of such acceleration or to collect unearned
interest at the time of such acceleration.

                                   9. WAIVERS

                  (a)      Except as specifically provided in the Loan
Documents, Borrower and any endorsers, sureties or guarantors hereof jointly and
severally waive presentment and demand for payment, notice of intent to
accelerate maturity, notice of acceleration of maturity, protest and notice of
protest and non-payment, all applicable exemption rights, valuation and
appraisement, notice of demand, and all other notices in connection with the
delivery, acceptance, performance, default or enforcement of the payment of this
Note and the bringing of suit and diligence in taking any action to collect any
sums owing hereunder or in proceeding against any of the rights and collateral
securing payment hereof. Borrower and any surety, endorser or guarantor hereof
agree (i) that the time for any payments hereunder may be extended from time to
time without notice and consent, (ii) to the acceptance by Lender of further
collateral, (iii) the release by Lender of any existing collateral for the
payment of this Note, (iv) to any and all renewals, waivers or modifications
that may be granted by Lender with respect to the payment or other provisions of
this Note, and/or (v) that additional Borrowers, endorsers, guarantors or
sureties may become parties hereto all without notice to them and without in any
manner affecting their liability under or with respect to this Note. No
extension of time for the payment of this Note or any installment hereof shall
affect the liability of Borrower under this Note or any endorser or guarantor
hereof even though the Borrower or such endorser or guarantor is not a party to
such agreement.

                  (b)      Failure of Lender to exercise any of the options
granted herein to Lender upon the happening of one or more of the events giving
rise to such options shall not constitute a waiver of the right to exercise the
same or any other option at any subsequent time in respect to the same or any
other event. The acceptance by Lender of any payment hereunder that is less than
payment in full of all amounts due and payable at the time of such payment shall
not constitute a waiver of the right to exercise any of the options granted
herein to Lender at that time or at any subsequent time or nullify any prior
exercise of any such option without the express written acknowledgment of the
Lender.

                                 10. EXCULPATION

                  (a)      Notwithstanding anything in the Loan Documents to the
contrary, but subject to the qualifications below, Lender and Borrower agree
that:

                           (i)      Borrower shall be liable upon the Debt and
         for the other obligations arising under the Loan Documents to the full
         extent (but only to the extent) of the security therefor; provided,
         however, that in the event (A) of fraud, wilful misconduct or material
         misrepresentation by Borrower, its members, its principals, its
         affiliates, its agents or its employees or by any Guarantor or any
         Indemnitor in connection with the loan evidenced by this Note, (B) of
         Borrower's breach or default under Section 8.2 of the

                                                   MORGAN GUARANTY TRUST COMPANY

         Security Instrument, or (C) the Property or any part thereof becomes an
         asset in a voluntary bankruptcy or insolvency proceeding, the
         limitation on recourse set forth in this Subsection 10(a) will be null
         and void and completely inapplicable, and this Note shall be with full
         recourse to Borrower.

                  (ii)     If a default occurs in the timely and proper payment
         of all or any part of the Debt, 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 the Security Instrument, the Other Loan
         Documents and the interest in the Property, the Rents and any other
         collateral given to Lender created by the Security Instrument and the
         Other Loan Documents; provided, however, that any judgment in any
         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
         herein provided, sue for, seek or demand any deficiency judgment
         against Borrower in any action or proceeding, under or by reason of or
         under or in connection with this Note, the Other Loan Documents or the
         Security Instrument.

                  (iii)    The provisions of this Subsection 10(a) shall not (A)
         constitute a waiver, release or impairment of any obligation evidenced
         or secured by this Note, the Other Loan Documents or the Security
         Instrument; (B) 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; (C) 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 Loan
         Documents; (D) impair the right of Lender to obtain the appointment of
         a receiver; (E) impair the enforcement of the Assignment executed in
         connection herewith; (F) impair the right of Lender to enforce the
         provisions of Article 11 of the Security Instrument; or (G) impair the
         right of Lender to obtain a deficiency judgment or judgment on this
         Note, against Borrower if necessary to obtain any insurance proceeds or
         condemnation awards to which Lender would otherwise be entitled under
         the Security Instrument; provided, however, Lender shall only enforce
         such judgment against the insurance proceeds and/or condemnation
         awards.

                  (iv)     Notwithstanding the provisions of this Article to the
         contrary, Borrower shall be personally liable to Lender for the Losses
         it incurs due to: (A) the misapplication or misappropriation of Rents;
         (B) the misapplication or misappropriation of insurance proceeds or
         condemnation awards; (C) Borrower's failure to return or to reimburse
         Lender for all Personal Property 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; (D) any act of actual waste
         or arson by Borrower, any principal, affiliate, general partner or
         member thereof or by any Indemnitor or any Guarantor; (E) any fees or
         commissions paid by Borrower to any principal, affiliate, general
         partner or member of Borrower, any Indemnitor or any Guarantor in
         violation of the terms of this Note, the Security

         comply with the provisions of Section 11.2 of the Security Instrument;
         or (G) any breach of the Environmental Indemnity.

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

                                  11. AUTHORITY

         Borrower (and the undersigned representative of Borrower, if any)

                               17. NO ORAL CHANGE

         The provisions of this Note and the Loan Documents may be amended or
revised only by an instrument in writing signed by the Borrower and Lender. This
Note and all the other Loan Documents embody the final, entire agreement of
Borrower and Lender and supersede any and all prior commitments, agreements,
representations and understandings, whether written or oral, relating to the
subject matter hereof and thereof and may not be contradicted or varied by
evidence of prior, contemporaneous or subsequent oral agreements or discussions
of Borrower and Lender. There are no oral agreements between Borrower and
Lender.

          17B.. ESTABLISHMENT OF COLLATERAL ACCOUNT - LOCKBOX AGREEMENT

         Except as expressly set forth in section 18(a)(v) of this Note,
Borrower hereby covenants and agrees, on or before the Collateral Account
Effective Date (as hereinafter defined), to enter into one or more clearing and
deposit agreements acceptable to Lender between Borrower, Lender and one or more
financial institutions (which may be Lender or an affiliate or subsidiary of
Lender) acceptable to Lender (together with any modification, amendment,
substitution or replacement thereof, hereinafter collectively referred to as the
"Lock-Box Agreement") in form and substance satisfactory to Lender which shall
provide, among other things, that all Rents and other sums collected from, or
arising with respect to, the Property be deposited in the deposit account (the
"Collateral Account") established in connection with such Lock-Box Agreement,
and that such amounts shall be disbursed in accordance with this Note. Borrower
shall not have a right of withdrawal in respect to the Collateral Account.
Borrower shall pay all costs and expenses required under the Lock-Box Agreement
or in connection with the Collateral Account and all of Lender's out-of-pocket
costs and expenses in connection with the preparation and negotiation of the
Lock-Box Agreement. On or before the Collateral Account Effective Date, Borrower
shall deliver to Lender for delivery, at Borrower's expense, by certified mail,
return receipt requested, to all tenants of the Property an irrevocable written
notice in form and substance satisfactory to Lender directing such tenants to
pay their rent and other amounts due under their leases to the depository under
the Lock-Box Agreement for deposit into the Collateral Account. Additionally,
each lease, license and occupancy agreement executed after the Collateral
Account Effective Date affecting any of the Property must provide, in a manner
approved by Lender, that tenant, lessee or licensee, as appropriate, is required
to make all payments due to Borrower under the terms of such lease, license or
occupancy agreement to the depository of the Collateral Account by check,
cashiers check or money order made payable to Lender or its successors or
assigns. Upon the occurrence of any default under this Note or the Security
Instrument, Lender may apply any sums then held pursuant to the Lock-Box
Agreement to the payment of the Obligations (as defined in the Security
Instrument) in any order in its sole discretion. Until expended or applied,
amounts held in the Collateral Account pursuant to the Lock-Box Agreement shall
constitute additional security for the Obligations. The Lock-Box Agreement when
and if executed shall be a "Loan Document" for all purposes under this Note, the
Security Instrument and the other Loan Documents. Borrower hereby irrevocably
constitutes and appoints Lender the attorney-in-fact of Borrower, coupled with
an interest, to, upon Borrower's failure to do so in accordance with the terms
hereof, without notice to Borrower, execute and deliver the Lock-Box Agreement
and the notices to tenants described in this Section 17B and to take any other
action necessary or desirable in Lender's judgment to carry out the intention of
this Section 17B.

         collect from the Collateral Account (as defined in Section 19 below) to
         the extent of funds on deposit in such account, on the Collateral
         Account Effective Date and on the first day of each calendar month
         thereafter, up to but excluding the Anticipated Repayment Date the
         following payments to be applied by Lender in the listed order of
         priority:

                           (1)      First, to the payment of the amount set
                  forth in Section 1(b) of this Note (the "MONTHLY DEBT SERVICE
                  PAYMENT AMOUNT") to be applied first to the payment of
                  interest computed at the Initial Interest Rate with the
                  remainder applied to the reduction of the outstanding
                  principal balance of this Note;

                           (2)      Second, to payments to the Tax and Insurance

                  of the Escrow Agreement;

                           (4)      Fourth, to payments for monthly Operating
                  Expenses (as hereinafter defined), pursuant to the terms and
                  conditions of the related Approved Budget (as hereinafter
                  defined);

                           (5)      Fifth, to payment for Extraordinary Expenses
                  (as hereinafter defined) approved by Lender, if any;

                  under the Loan Documents; and

                           (7)      Lastly, any excess amounts shall remain on
                  deposit in the Collateral Account.

                  (ii)     For the calendar year in which the Collateral Account
         Effective Date occurs and for each calendar year thereafter until this
         Note is paid in full, Borrower shall submit to Lender for Lender's
         written approval an annual budget (an "ANNUAL BUDGET") not later than
         (i) 60 days prior to the Collateral Account Effective Date for the
         calendar year in which the Collateral Account Effective Date occurs and
         (ii) sixty (60) days prior to the commencement of each calendar year
         thereafter, in form satisfactory to Lender setting forth in reasonable
         detail budgeted monthly operating income and monthly operating capital
         and other expenses for the Property. Each Annual Budget shall contain,
         among other things, limitations on management fees, third party service
         fees and other expenses as Lender may reasonably determine. Each Annual
         Budget must be satisfactory

<PAGE>

         to Lender in its sole discretion and each such Annual Budget approved
         by Lender in accordance with the terms hereof shall hereinafter be
         referred to as an "Approved Budget." Until such time as Lender approves
         a proposed Annual Budget, the most recently Approved Budget shall
         apply; provided, that such Approved Budget shall be adjusted to reflect
         actual increases in real estate taxes, insurance premiums and utilities
         expenses.

                  (iii)    In the event that Borrower must incur any
         extraordinary operating expense or capital expense not set forth in the
         applicable Approved Budget or reserved for in the On-going Replacement
         Fund (each, an "EXTRAORDINARY EXPENSE"), then Borrower shall promptly
         deliver to Lender a reasonably detailed explanation of such proposed
         Extraordinary Expense for Lender's approval.

                  (iv)     For the purposes of this Note, "OPERATING EXPENSES"
         shall mean, for any period, the operating expenses for the operation
         and maintenance of the Property as set forth in an Approved Budget to
         the extent such expenses are actually paid by Borrower and excluding
         (1) expenses for which Borrower shall be reimbursed from, or which
         shall be paid for out of, any Funds (as defined in the Escrow
         Agreement), and (2) any management fees payable to affiliates of the
         Borrower unless Lender has approved the same in its sole discretion
         pursuant to an Approved Budget or otherwise pursuant to a management
         agreement approved by Lender.

                  (v)      Notwithstanding the other provisions of this Section
         18(a), in the event that, not less than ten (10) business days prior to
         the Collateral Account Effective Date, Borrower delivers to Lender
         either (i) a written commitment (the "COMMITMENT") for the refinancing
         of the Loan evidenced by this Note from a Qualified Lender (as
         hereinafter, defined), which reasonably provides for the consummation
         of such refinance prior to the Anticipated Repayment Date or (ii) other
         evidence in form and substance satisfactory to Lender in its sole
         determination of Borrower's ability to refinance the loan evidenced by
         this Note prior to the Collateral Account Effective Date, then, in
         either such event, the terms of Sections 17B and 18(a)(i), (a)(ii),
         (a)(iii) and (a)(iv) of this Note shall be inoperative, provided,
         however, that upon (x) the failure of such refinance to be consummated
         in accordance with the terms of the Commitment or such other evidence,
         as applicable, (y) the termination of the Commitment for any reason or
         (z) any adverse change in circumstances with respect to Borrower or any
         principals of Borrower, the Property, the proposed lender or otherwise,
         as determined by Lender in its sole determination, which, if Lender's
         reasonable judgment, significantly decreases the likelihood of such

and the terms and conditions of that certain Assignment of Rents and Leases, of
even date herewith between Borrower and Lender, Lender grants to Borrower a
revocable license to collect and receive the Rents. Borrower shall hold the

hereafter held by Lender, including, without limitation, any sums deposited in
the Funds (as defined in the Escrow Agreement), all insurance proceeds described

additional security for the Obligations until expended or applied as provided in
this Security Instrument.

         TO HAVE AND TO HOLD the above granted and described Property unto and
to the use and benefit of Trustee, and the successors and assigns of Trustee,
forever;

         PROVIDED, HOWEVER, these presents are upon the express condition that,
if Borrower shall well and truly pay to Lender the Debt at the time and in the
manner provided in the Note and this Security Instrument, shall well and truly
perform the Other Obligations as set forth in this Security Instrument and shall
well and truly abide by and comply with each and every covenant and condition
set forth herein and in the Note, these presents and the estate hereby granted
shall cease, terminate and be void; provided however, that Borrower's obligation
to indemnify and hold harmless Lender pursuant to the provisions hereof with
respect to matters relating to any period of time during which this Security
Instrument was in effect shall survive any such payment or release.

         Section 2.4 - PAYMENTS

                  Unless payments are made in the required amount in immediately
available funds at the place where the Note is payable, remittances in payment
of all or any part of the Debt shall not, regardless of any receipt or credit
issued therefor, constitute payment until the required amount is actually
received by Lender in funds immediately available at the place where the Note is
payable (or any other place as Lender, in Lender's sole discretion, may have
established by delivery of written notice thereof to Borrower) and shall be made
and accepted subject to the condition that any check or draft may be handled for
collection in accordance with the practice of the collecting bank or banks.
Acceptance by Lender of any payment in an amount less than the amount then due

         Borrower covenants and agrees that:

         Section 3.1 - INCORPORATION BY REFERENCE

                  All the covenants, conditions and agreements contained in (a)
the Note, and (b) all and any of the documents other than the Note or this
Security Instrument now or hereafter executed by Borrower and/or others and by
or in favor of Lender in connection with the creation of the Obligations, the
payment of any other sums owed by Borrower to Lender or the performance of any
Obligations (collectively the "Other Loan Documents"), are hereby made a part of
this Security Instrument to the same extent and with the same force as if fully
set forth herein. The term "Loan Documents" as used herein shall individually
and collectively refer to the Note, this Security Instrument and the Other Loan
Documents; provided, however, that notwithstanding any provision of this
Security Instrument to the contrary, the Obligations of the indemnitor(s) under
that certain Environmental Indemnity Agreement of even date herewith executed by
Borrower and Douglas Donatelli, Nicholas Smith and Louis Donatelli (whether one
or more, "Indemnitor")] in favor of Lender (the "Environmental Indemnity") shall
not be deemed or construed to be secured by this Security Instrument or
otherwise restricted or affected by the foreclosure of the lien hereof or any
other exercise by Lender of its remedies hereunder or under any other Loan
Document, such Environmental Indemnity being intended by the signatories thereto
to be its (or their) unsecured obligation.

and in each case (A) in an amount equal to the lesser of the principal balance

this Security Instrument shall mean actual replacement value (exclusive of costs
of excavations, foundations, underground utilities and footings) with a waiver
of depreciation; (B) containing an agreed amount endorsement with respect to the

percent (1%) of the face value of the policy; and (D) containing Demolition
Costs, Increased Cost of Construction and "Ordinance or Law Coverage" or

ability to rebuild the Improvements is restricted or prohibited. The Full
Replacement Cost may be redetermined from time to time by an appraiser or
contractor designated and paid by Lender or by an engineer or appraiser in the
regular employ of the insurer. No omission on the part of Lender to request any
such appraisals shall relieve Borrower of any of its obligations under this
Subsection;

                           (ii)     comprehensive general liability insurance
against claims for personal injury, bodily injury, death or property damage

elevators, as well as liquor liability insurance in a minimum amount of
$2,000,000.00 if any part of the Property is covered by a liquor license; (B) to
continue at not less than the aforesaid limit until required to be changed by
Lender in writing by reason of changed economic conditions making such
protection inadequate; (C) to cover at least the following hazards: (1) premises
and operations; (2) products and completed operations on an "if any" basis; (3)
independent contractors; (4) blanket contractual liability for all written and
oral contracts; (5) contractual liability covering the indemnities contained in
Article 11 hereof to the extent the same is available; and (D) to be without
deductible;

                           (iii)    business income insurance (A) with loss
payable to Lender; (B) covering losses of income and Rents derived from the
Property and any non-insured property on or adjacent to the Property resulting
from any risk or casualty whatsoever; (C) containing an extended period of
indemnity endorsement which provides that after the physical loss to the
Improvements and Personal Property has been repaired, the continued loss of
income will be insured until such income either returns to the same level it was
at prior to the loss, or the expiration of eighteen (18) months from the date of
the loss, whichever first occurs, and notwithstanding that the policy may expire
prior to the end of such period; and (D) in an amount equal to 100% of the
projected gross income from the Property for a period of eighteen (18) months.
The amount of such business income insurance shall be determined by Lender prior
to the date hereof and at least once each year thereafter based on Borrower's
reasonable estimate of the gross income from the Property for the succeeding
eighteen (18) month period. All insurance proceeds payable to Lender pursuant to
this Subsection 3.2(a) shall be held by Lender and shall be applied to the
obligations secured hereunder from time to time due and payable hereunder and
under the Note; provided, however, that nothing herein contained shall be deemed
to relieve Borrower of its obligations to pay the obligations secured hereunder
on the respective dates of payment provided for in the Note except to the extent
such amounts are actually paid out of the proceeds of such business income
insurance;

rating of A- or better and a financial class of VIII or better by A.M. Best Co.
or claims paying ability rating of A or better issued by Standard & Poor's
Ratings Group (each such insurer shall be referred to below as a "Qualified
Insurer"). Such Policies shall not be subject to invalidation due to the use or
occupancy of the Property for purposes more hazardous than the use of the
Property at the time such Policies were issued. Not less than thirty (30) days
prior to the expiration dates of the Policies theretofore furnished to Lender
pursuant to Subsection 3.2(a), certified copies of the Policies marked "premium
paid" or accompanied by evidence satisfactory to Lender of payment of the
premiums due thereunder (the "Insurance Premiums"), shall be delivered by
Borrower to Lender; provided, however, that in the case of renewal Policies,
Borrower may furnish Lender with binders therefor to be followed by the original
Policies when issued.

                  (c)      Borrower shall not obtain (i) separate insurance
concurrent in form or contributing in the event of loss with that required in
Subsection 3.2(a) to be furnished by, or which may be reasonably required to be
furnished by, Borrower, or (ii) any umbrella or blanket liability or casualty
Policy unless, in each case, Lender's interest is included therein as provided
in this Security Instrument and such Policy is issued by a Qualified Insurer. If
Borrower obtains separate insurance or an umbrella or a blanket Policy, Borrower
shall notify Lender of the same and shall cause certified copies of each Policy
to be delivered as required in Subsection 3.2(a). Any blanket insurance Policy
shall specifically allocate to the Property the amount of coverage from time to
time required hereunder and shall otherwise provide the same protection as would
a separate Policy insuring only the Property in compliance with the provisions
of Subsection 3.2(a).

                  (d)      All Policies of insurance provided for or
contemplated by Subsection 3.2(a) shall name Lender, its successors and assigns,
including any servicers, trustees or other designees of Lender, and Borrower as
the insured or additional insured, as their respective interests may appear, and
in the case of property damage, boiler and machinery, and flood insurance, shall
contain a so-called New York standard non-contributing Lender clause in favor of
Lender providing that the loss thereunder shall be payable to Lender.

                  (e)      All Policies of insurance provided for in Subsection
3.2(a) shall contain clauses or endorsements to the effect that:

                           (i)      no act or negligence of Borrower, or anyone
acting for Borrower, or of any tenant under any Lease or other occupant, or
failure to comply with the provisions of any Policy which might otherwise result
in a forfeiture of the insurance or any part thereof, shall in any way affect
the validity or enforceability of the insurance insofar as Lender is concerned;

                           (ii)     the Policy shall not be materially changed
(other than to increase the coverage provided on the Property thereby) or
canceled without at least thirty (30) days' prior written notice to Lender and
any other party named therein as an insured;

                           (iii)    each Policy shall provide that the issuers
thereof shall give written notice to Lender if the Policy has not been renewed
thirty (30) days prior to its expiration; and

                           (iv)     Lender shall not be liable for any Insurance
Premiums thereon or subject to any assessments thereunder.

                  (f)      Borrower shall furnish to Lender within ten (10)
calendar days after Lender's request therefor, a statement certified by Borrower
or a duly authorized officer of Borrower of the amounts of insurance maintained
in compliance herewith, of the risks covered by such insurance and of the
insurance company or companies which carry such insurance and, if requested by
Lender, verification of the adequacy of such insurance by an independent
insurance broker or appraiser acceptable to Lender.

                  (g)      If at any time Lender is not in receipt of written
evidence that all insurance required hereunder is in full force and effect,
Lender shall have the right but not the obligation, without notice to Borrower,
to take such action as Lender deems necessary to protect its interest in the
Property, including, without limitation, the obtaining of such insurance
coverage as Lender in its sole discretion deems appropriate, and all expenses
incurred by Lender in connection with such action or in obtaining such insurance
and keeping it in effect shall be paid by Borrower to Lender upon demand and
until paid shall be secured by this Security Instrument and shall bear interest
at the Default Rate (as hereinafter defined).

                  (h)      If the Property shall be damaged or destroyed, in
whole or in part, by fire or other casualty, Borrower shall give prompt notice
thereof to Lender.

                           (i)      In case of loss covered by Policies, Lender
may either (1) settle and adjust any claim without the consent of Borrower, or
(2) allow Borrower to agree with the insurance company or companies on the
amount to be paid upon the loss; provided, that Borrower may adjust losses
aggregating not in excess of $100,000.00 if such adjustment is carried out in a
competent and timely manner, and provided that in any case Lender shall and is
hereby authorized to collect and receive any such insurance proceeds; and the
expenses incurred by Lender in the adjustment and collection of insurance
proceeds shall become part of the Debt and be secured hereby and shall be
reimbursed by Borrower to Lender upon demand (unless deducted by and reimbursed
to Lender from such proceeds). Notwithstanding the foregoing, provided there has
been no Event of Default (hereinafter defined), if the potential loan proceeds
exceed the outstanding principal amount of the Loan then Borrower may settle and
adjust any such claim.

                           (ii)     In the event of any insured damage to or
destruction of the Property or any part thereof (herein called an "Insured
Casualty"), if (A) in the reasonable judgment of Lender, the Property can be
restored within Nine Months after insurance proceeds are made available to an
economic unit not less valuable (including an assessment by Lender of the impact
of the termination of any Leases due to such Insured Casualty) and not less
useful than the same was prior to the Insured Casualty, and after such
restoration will adequately secure the outstanding balance of the Debt, and (B)
no Event of Default (hereinafter defined) shall have occurred and be then
continuing, then the proceeds of insurance shall be applied to reimburse
Borrower for the cost of restoring, repairing, replacing or rebuilding the
Property or part thereof subject to Insured Casualty, as provided below; and
Borrower hereby covenants and agrees forthwith to commence and diligently to
prosecute such restoring, repairing, replacing or

                                                   MORGAN GUARANTY TRUST COMPANY

rebuilding; provided, however, in any event Borrower shall pay all costs (and if
required by Lender, Borrower shall deposit the total thereof with Lender in
advance) of such restoring, repairing, replacing or rebuilding in excess of the
net proceeds of insurance made available pursuant to the terms hereof.

                           (iii)    Except as provided above, the proceeds of
insurance collected upon any Insured Casualty shall, at the option of Lender in
its sole discretion, be applied to the payment of the Debt or applied to
reimburse Borrower for the cost of restoring, repairing, replacing or rebuilding
the Property or part thereof subject to the Insured Casualty, in the manner set
forth below. Any such application to the Debt shall not be considered a
voluntary prepayment requiring payment of the prepayment consideration provided
in the Note, and shall not reduce or postpone any payments otherwise required
pursuant to the Note, other than the final payment on the Note.

                           (iv)     If proceeds of insurance, if any, are made
available to Borrower for the restoring, repairing, replacing or rebuilding of
the Property, Borrower hereby covenants to restore, repair, replace or rebuild
the same to be of at least equal value and of substantially the same character
as prior to such damage or destruction, all to be effected in accordance with
applicable law and plans and specifications approved in advance by Lender.

                           (v)      If Borrower is entitled to reimbursement out
of insurance proceeds held by Lender, such proceeds shall be disbursed from time
to time upon Lender being furnished with (1) evidence satisfactory to it (which
evidence may include inspection[s] of the work performed) that the restoration,
repair, replacement and rebuilding covered by the disbursement has been
completed in accordance with plans and specifications approved by Lender, (2)
evidence satisfactory to it of the estimated cost of completion of the
restoration, repair, replacement and rebuilding, (3) funds, or, at Lender's
option, assurances satisfactory to Lender that such funds are available,
sufficient in addition to the proceeds of insurance to complete the proposed
restoration, repair, replacement and rebuilding, and (4) such architect's
certificates, waivers of lien, contractor's sworn statements, title insurance
endorsements, bonds, plats of survey and such other evidences of cost, payment
and performance as Lender may reasonably require and approve; and Lender may, in
any event, require that all plans and specifications for such restoration,
repair, replacement and rebuilding be submitted to and approved by Lender prior
to commencement of work. With respect to disbursements to be made by Lender: (A)
no payment made prior to the final completion of the restoration, repair,
replacement and rebuilding shall exceed ninety percent (90%) of the value of the
work performed from time to time; (B) funds other than proceeds of insurance
shall be disbursed prior to disbursement of such proceeds; and (C) at all times,
the undisbursed balance of such proceeds remaining in the hands of Lender,
together with funds deposited for that purpose or irrevocably committed to the
satisfaction of Lender by or on behalf of Borrower for that purpose, shall be at
least sufficient in the reasonable judgment of Lender to pay for the cost of
completion of the restoration, repair, replacement or rebuilding, free and clear
of all liens or claims for lien and the costs described in Subsection 3.2(h)(vi)
below. Any surplus which may remain out of insurance proceeds held by Lender
after payment of such costs of restoration, repair, replacement or rebuilding
shall be paid to any party entitled thereto. In no event shall Lender assume any
duty or obligation for the adequacy, form

or content of any such plans and specifications, nor for the performance,
quality or workmanship of any restoration, repair, replacement and rebuilding.

                           (vi)     Notwithstanding anything to the contrary
contained herein, the proceeds of insurance reimbursed to Borrower in accordance
with the terms and provisions of this Security Instrument shall be reduced by
the reasonable costs (if any) incurred by Lender in the adjustment and
collection thereof and in the reasonable costs incurred by Lender of paying out
such proceeds (including, without limitation, reasonable attorneys' fees and
costs paid to third parties for inspecting the restoration, repair, replacement
and rebuilding and reviewing the plans and specifications therefor).

         Section 3.3 - PAYMENT OF TAXES, ETC.

                  (a)      Borrower shall pay all taxes, assessments, water
rates, sewer rents, governmental impositions, and other charges, including
without limitation, vault charges and license fees for the use of vaults, chutes
and similar areas adjoining the Land, now or hereafter levied or assessed or
imposed against the Property or any part thereof (the "Taxes"), all ground
rents, maintenance charges and similar charges, now or hereafter levied or
assessed or imposed against the Property or any part thereof (the "Other
Charges"), and all charges for utility services provided to the Property as same
become due and payable. Borrower will deliver to Lender, promptly upon Lender's
request, evidence satisfactory to Lender that the Taxes, Other Charges and
utility service charges have been so paid or are not then delinquent. Borrower
shall not allow and shall promptly cause to be paid and discharged any lien or
charge whatsoever which may be or become a lien or charge against the Property.
Except to the extent sums sufficient to pay all Taxes and Other Charges have
been deposited with Lender in accordance with the terms of this Security
Instrument, Borrower shall furnish to Lender paid receipts for the payment of
the Taxes and Other Charges prior to the date the same shall become delinquent.

                  (b)      After prior written notice to Lender, Borrower, at
its own expense, may contest by appropriate legal proceeding, promptly initiated
and conducted in good faith and with due diligence, the amount or validity or
application in whole or in part of any of the Taxes, provided that (i) no Event
of Default has occurred and is continuing under the Note, this Security
Instrument or any of the Other Loan Documents, (ii) Borrower is permitted to do
so under the provisions of any other mortgage, deed of trust or deed to secure
debt affecting the Property, (iii) such proceeding shall suspend the collection
of the Taxes from Borrower and from the Property or Borrower shall have paid all
of the Taxes under protest, (iv) such proceeding shall be permitted under and be
conducted in accordance with the provisions of any other instrument to which
Borrower is subject and shall not constitute a default thereunder, (v) neither
the Property nor any part thereof or interest therein will be in danger of being
sold, forfeited, terminated, canceled or lost, (vi) Borrower shall have set
aside and deposited with Lender adequate reserves for the payment of the Taxes,
together with all interest and penalties thereon, unless Borrower has paid all
of the Taxes under protest, and (vii) Borrower shall have furnished the security
as may be required in the proceeding, or as may be requested by Lender to insure
the payment of any contested Taxes, together with all interest and penalties
thereon.

         Section 3.4 - CONDEMNATION

                  (a)      Borrower shall promptly give Lender notice of the
actual or threatened commencement of any condemnation or eminent domain
proceeding and shall deliver to Lender copies of any and all papers served in
connection with such proceedings. Lender is hereby irrevocably appointed as
Borrower's attorney-in-fact, coupled with an interest, with exclusive power to
collect, receive and retain any award or payment for said condemnation or
eminent domain and to make any compromise or settlement in connection with such
proceeding, subject to the provisions of this Security Instrument.
Notwithstanding any taking by any public or quasi-public authority through
eminent domain or otherwise (including but not limited to any transfer made in
lieu of or in anticipation of the exercise of such taking), Borrower shall
continue to pay the Debt at the time and in the manner provided for its payment
in the Note and in this Security Instrument and the Debt shall not be reduced
until any award or payment therefor shall have been actually received and
applied by Lender, after the deduction of expenses of collection, to the
reduction or discharge of the Debt. Lender shall not be limited to the interest
paid on the award by the condemning authority but shall be entitled to receive
out of the award interest at the rate or rates provided herein or in the Note.
Borrower shall cause the award or payment made in any condemnation or eminent
domain proceeding, which is payable to Borrower, to be paid directly to Lender.
Lender may apply any award or payment to the reduction or discharge of the Debt
whether or not then due and payable (such application to be free from any
prepayment consideration provided in the Note, except that if an Event of
Default, or an event which with notice and/or the passage of time, or both,
would constitute an Event of Default, has occurred, then such application shall
be subject to the full prepayment consideration computed in accordance with the
Note). If the Property is sold, through foreclosure or otherwise, prior to the
receipt by Lender of the award or payment, Lender shall have the right, whether
or not a deficiency judgment on the Note shall have been sought, recovered or
denied, to receive the award or payment, or a portion thereof sufficient to pay
the Debt.

         Section 3.5 - USE AND MAINTENANCE OF PROPERTY

                  Borrower shall cause the Property to be maintained and
operated in a good and safe condition and repair and in keeping with the
condition and repair of properties of a similar use, value, age, nature and
construction. Borrower shall not use, maintain or operate the Property in any
manner which constitutes a public or private nuisance or which makes void,
voidable, or cancelable, or increases the premium of, any insurance then in
force with respect thereto. The Improvements and the Personal Property shall not
be removed, demolished or materially altered (except for normal replacement of
the Personal Property or system elements of the Improvements with items of the
same utility and of equal or greater value and non-structural alterations in
connection with tenant improvements under leases approved by Lender or for which
Lender's approval is not required under this Security Instrument) without the
prior written consent of Lender. Borrower shall promptly repair, replace or
rebuild any part of the Property which may be destroyed by any casualty, or
become damaged, worn or dilapidated or which may be affected by any proceeding
of the character referred to in Section 3.4 hereof and shall complete and pay
for any structure at any time in the process of construction or repair on the
Land. Borrower shall not initiate, join in or consent to any change in any
private restrictive covenant, zoning law or other public or private restriction,
limiting or defining the uses which

                                                   MORGAN GUARANTY TRUST COMPANY

                                       13

<PAGE>

may be made of the Property or any part thereof which would decrease the value
of the Property. If under applicable zoning provisions the use of all or any
portion of the Property is or shall become a nonconforming use, Borrower will
not cause or permit the nonconforming use to be discontinued or abandoned
without the express written consent of Lender unless there are replacement
tenants with conforming uses.

Borrower shall not take any steps whatsoever to convert the Property, or any
portion thereof, to a condominium or cooperative form of management.

         Section 3.6 - WASTE

                  Borrower shall not commit or suffer any waste of the Property
or, without first obtaining such additional insurance as may be necessary to
cover a proposed change in use of the Property, make any change in the use of
the Property which will in any way materially increase the risk of fire or other
hazard arising out of the operation of the Property, or take any action that
might invalidate or give cause for cancellation of any Policy, or do or permit
to be done thereon anything that may in any way impair the value of the Property
or the security of this Security Instrument. Borrower will not, without the
prior written consent of Lender, permit any drilling or exploration for or
extraction, removal, or production of any minerals from the surface or the
subsurface of the Land, regardless of the depth thereof or the method of mining
or extraction thereof.

         Section 3.7 - COMPLIANCE WITH LAWS; ALTERATIONS

                  (a)      Borrower shall promptly comply with all existing and
future federal, state and local laws, orders, ordinances, governmental rules and
regulations or court orders affecting or which may be interpreted to affect the
Property, or the use thereof, including, but not limited to, the Americans with
Disabilities Act (the "ADA") (collectively "Applicable Laws").

                  (b)      Notwithstanding any provisions set forth herein or in
any document regarding Lender's approval of alterations of the Property,
Borrower shall not alter the Property in any manner which would increase
Borrower's responsibilities for compliance with Applicable Laws without the
prior written approval of Lender. Lender's approval of the plans,
specifications, or working drawings for alterations of the Property shall create
no responsibility or liability on behalf of Lender for their completeness,
design, sufficiency or their compliance with Applicable Laws. The foregoing
shall apply to tenant improvements constructed by Borrower or by any of its
tenants. Lender may condition any such approval upon receipt of a certificate of
compliance with Applicable Laws from an independent architect, engineer, or
other person acceptable to Lender.

                  (c)      Borrower shall give prompt notice to Lender of the
receipt by Borrower of any notice related to a violation of any Applicable Laws
and of the commencement of any proceedings or investigations which relate to
compliance with Applicable Laws.

                  (d)      Borrower shall take appropriate measures to prevent
and will not engage in or knowingly permit any illegal activities at the
Property.

         Section 3.8 - BOOKS AND RECORDS

                  (a)      Borrower shall keep accurate books and records of
account in accordance with sound accounting principles in which full, true and
correct entries shall be promptly made with respect to Borrower, the Property
and the operation thereof, and will permit all such books and records (including
without limitation all contracts, statements, invoices, bills and claims for
labor, materials and services supplied for the construction, repair or operation
to Borrower of the Improvements) to be inspected or audited and copies made by
Lender and its representatives during normal business hours and at any other
reasonable times upon reasonable advance written notice except in emergencies.
Borrower represents that its chief executive office is as set forth in the
introductory paragraph of this Security Instrument and that all books and
records pertaining to the Property are maintained at the Property or such other
location as may be expressly disclosed to Lender in writing. Borrower will
furnish, or cause to be furnished, to Lender on or before forty-five (45)
calendar days after the end of each calendar quarter the following items, each
certified by Borrower as being true and correct, in such format and in such
detail as Lender or its servicer may request:

                           (i)      a written statement (rent roll) dated as of
the last day of each such calendar quarter identifying each of the Leases by the
term, space occupied, rental required to be paid (including percentage rents and
tenant sales), security deposit paid, any rental concessions, all rent
escalations, any rents paid more than one (1) month in advance, any special
provisions or inducements granted to tenants, any taxes, maintenance and other
common charges paid by tenants, all vacancies and identifying any defaults or
payment delinquencies thereunder; and

                           (ii)     quarterly and year-to-date operating
statements prepared for each calendar quarter during each such reporting period
detailing the total revenues received, total expenses incurred, total cost of
all capital improvements, total debt service and total cash flow.

                  (b)      Within ninety (90) calendar days following the end of
each calendar year, Borrower shall furnish a statement of the financial affairs
and condition of the Borrower and the Property including a statement of profit
and loss for the Property in such format and in such detail as Lender or its
servicer may request, and setting forth the financial condition and the income
and expenses for the Property for the immediately preceding calendar year
prepared by an independent certified public accountant. Borrower shall deliver
to Lender copies of all income tax returns, requests for extension and other
similar items contemporaneously with its delivery of same to the Internal
Revenue Service.

                  (c)      Borrower will permit representatives appointed by
Lender, including independent accountants, agents, attorneys, appraisers and any
other persons, upon reasonable advance notice except in emergencies, subject to
the rights of tenants, to visit and inspect during its normal business hours and
at any other reasonable times any of the Property and to make photographs
thereof, and to write down and record any information such representatives
obtain, and shall permit Lender or its representatives to investigate and verify
the accuracy of the information furnished to Lender under or in connection with
this Security Instrument or any of the Other Loan Documents and to discuss all
such matters with its officers, employees and representatives. Borrower will
furnish to Lender at Borrower's expense all evidence which

                                       15

<PAGE>

Lender may from time to time reasonably request as to the accuracy and validity
of or compliance with all representations and warranties made by Borrower in the
Loan Documents and satisfaction of all conditions contained therein. Any
inspection or audit of the Property or the books and records of Borrower, or the
procuring of documents and financial and other information, by or on behalf of
Lender, shall be for Lender's protection only, and shall not constitute any
assumption of responsibility or liability by Lender to Borrower or anyone else
with regard to the condition, construction, maintenance or operation of the
Property, nor Lender's approval of any certification given to Lender nor relieve
Borrower of any of Borrower's obligations.

         Section 3.9 - PAYMENT FOR LABOR AND MATERIALS

                  Borrower will promptly pay when due all bills and costs for
labor, materials, and specifically fabricated materials incurred in connection
with the Property and never permit to exist beyond the due date thereof in
respect of the Property or any part thereof any lien or security interest, even
though inferior to the liens and the security interests hereof, and in any event
never permit to be created or exist in respect of the Property or any part
thereof any other or additional lien or security interest other than the liens
or security interests hereof, except for the Permitted Exceptions (as
hereinafter defined).

         Section 3.10 - PERFORMANCE OF OTHER AGREEMENTS

                  Borrower shall observe and perform each and every term to be
observed or performed by Borrower pursuant to the terms of any agreement or
recorded instrument affecting or pertaining to the Property, or given by
Borrower to Lender for the purpose of further securing an obligation secured
hereby and any amendments, modifications or changes thereto.

                         ARTICLE 4 - SPECIAL COVENANTS

         Borrower covenants and agrees that:

         Section 4.1 - PROPERTY USE

                  The Property shall be used only for office/warehouse purposes,
and for no other use without the prior written consent of Lender, which consent
may be withheld in Lender's sole and absolute discretion.

         Section 4.2 - ERISA

                  (a)      It shall not engage in any transaction which would
cause any obligation, or action taken or to be taken, hereunder (or the exercise
by Lender of any of its rights under the Note, this Security Instrument and the
Other Loan Documents) to be a non-exempt (under a statutory or administrative
class exemption) prohibited transaction under the Employee Retirement Income
Security Act of 1974, as amended ("ERISA").

                  (b)      It shall deliver to Lender such certifications or
other evidence from time to time throughout the term of the Security Instrument,
as requested by Lender in its sole discretion, that (i) Borrower is not an
"employee benefit plan" as defined in Section 3(3) of ERISA, which is subject to
Title I of ERISA, or a "governmental plan" within the meaning of Section 3(32)
of ERISA; (ii) Borrower is not subject to state statutes regulating investments

outstanding class of equity interests in Borrower are held by "benefit plan
investors" within the meaning of 29 C.F.R. Section 2510.3-101(f)(2); or

                           (iii)    Borrower qualifies as an "operating company"
or a "real estate operating company" within the meaning of 29 C.F.R. Section
2510.3-101 (c) or (e) or an investment company registered under The Investment
Company Act of 1940.

         Section 4.3 - SINGLE PURPOSE ENTITY

                  Borrower covenants and agrees that it has not and shall not:

                  (a)      engage in any business or activity other than the

dispose of all or substantially all of its assets or change its legal structure,
without in each case Lender's consent;

                  (d)      fail to preserve its existence as an entity duly
organized, validly existing and in good standing (if applicable) under the laws
of the jurisdiction of its organization or formation, or without the prior
written consent of Lender, amend, modify, terminate or fail to comply with the
provisions of Borrower's Partnership Agreement, Articles or Certificate of

STAMP LAWS

                  (a)      If any law is enacted or adopted or amended after the
date of this Security Instrument which imposes a tax, either directly or
indirectly, on the Debt or Lender's interest in the Property, requires revenue
or other stamps to be affixed to the Note, this Security Instrument, or the
Other Loan Documents, or imposes any other tax or charge on the same, Borrower
will pay the same, with interest and penalties thereon, if any. If Lender is
advised by counsel chosen by it that the payment of tax by Borrower would be
unlawful or taxable to Lender or unenforceable or provide the basis for a
defense of usury, then Lender shall have the option, by written notice of not
less than ninety (90) calendar days, to declare the Debt immediately due and
payable.

                  (b)      Borrower will not claim or demand or be entitled to

any part thereof, for real estate tax purposes by reason of this Security
Instrument or the Debt. If such claim, credit or deduction shall be required by
law, Lender shall have the option, by written notice of not less than ninety
(90) calendar days, to declare the Debt immediately due and payable.

amount of the original principal amount of the Note, (ii) the unpaid principal
amount of the Note, (iii) the rate of interest of the Note, (iv) the terms of
payment and maturity date of the Note, (v) the date installments of interest
and/or principal were last paid, and (vi) that, except as provided in such
statement, there are no defaults or events which with the passage of time or the
giving of notice or both, would constitute an event of default under the Note or
this Security Instrument; provided, however, Lender shall not be entitled
hereunder to receive more than one (1) such statement in each calendar year.

                  (b)      Subject to the provisions of the Leases, Borrower
shall deliver to Lender, promptly upon request (but not more frequently than
once annually so long as Borrower is not in default hereunder), duly executed
estoppel certificates from any one or more lessees as required by Lender
attesting to such facts regarding the Lease as Lender may require, including but

Rents have been paid more than one month in advance, and that the lessee claims
no defense or offset against the full and timely performance of its obligations
under the Lease.

                  (c)      Upon any transfer or proposed transfer contemplated
by Section 16.1 hereof, at Lender's request, Borrower, any Guarantors and any
Indemnitors shall provide an estoppel certificate to the Investor (defined in
Section 16.1) or any prospective Investor in such form, substance and detail as
Lender, such Investor or prospective Investor may require.

         Section 7.5 - [INTENTIONALLY OMITTED]

         Section 7.6 - REPLACEMENT DOCUMENTS

                  Upon receipt of an affidavit of an officer of Lender as to the
loss, theft, destruction or mutilation of the Note or any Other Loan Document
which is not of public record, and, in the case of any such mutilation, upon
surrender and cancellation of such Note or Other Loan Document, Borrower, at its
expense, will issue, in lieu thereof, a replacement Note or Other Loan Document,
dated the date of such lost, stolen, destroyed or mutilated Note or Other Loan
Document in the same principal amount thereof and otherwise of like tenor.

         Section 8.1 - LENDER RELIANCE

                  Borrower acknowledges that Lender has examined and relied on
the creditworthiness of Borrower and experience of Borrower and its general
partners, members, principals and (if Borrower is a trust) beneficial owners in
owning and operating properties such as the Property in agreeing to make the
Loan, and will continue to rely on Borrower's ownership of the Property as a
means of maintaining the value of the Property as security for repayment of the
Debt and the performance of the Other Obligations. Borrower acknowledges that
Lender has a valid interest in maintaining the value of the Property so as to
ensure that, should Borrower default in the repayment of the Debt or the
performance of the Other Obligations, Lender can recover the Debt by a sale of
the Property.

         Section 8.2 - NO SALE/ENCUMBRANCE

                  (a)      Borrower agrees that Borrower shall not, without the
prior written consent of Lender, sell, convey, mortgage, grant, bargain,
encumber, pledge, assign, or otherwise transfer the Property or any part thereof
or permit the Property or any part thereof to be sold, conveyed, mortgaged,
granted, bargained, encumbered, pledged, assigned, or otherwise transferred.
Lender shall not be required to demonstrate any actual impairment of its
security or any increased risk of default hereunder in order to declare the Debt
immediately due and payable upon Borrower's sale, conveyance, mortgage, grant,
bargain, encumbrance, pledge, assignment, or transfer of the Property without
Lender's consent.

voluntary or involuntary sale, conveyance or transfer of such corporation's
stock (or the stock of any corporation directly or indirectly controlling such
corporation by operation of law or otherwise) or the creation or issuance of new
stock in one or a series of transactions by which an aggregate often percent
(10%) or more of such corporation's stock shall be vested in a party or parties

traded on a nationally recognized stock exchange); (iv) if Borrower, Guarantor,
or any general partner of Borrower or Guarantor is a limited liability company
or limited partnership, the voluntary or involuntary sale, conveyance or
transfer by which an aggregate of fifty percent (50%) or more of the ownership
interest in such limited liability company or fifty percent (50%) or more of the
limited partnership interests in such limited partnership shall be vested in

no Event of Default under the Loan Documents has occurred and is continuing, and
if each of the following conditions precedent have been fully satisfied (as
determined in Lender's sole and absolute discretion): (i) the grantee's or
transferee's integrity, reputation, financial condition, character and
management ability are satisfactory to Lender in its sole discretion, and all
information relating thereto requested by Lender is delivered to Lender at least

its sole general partner's) single purpose and bankruptcy remote character are
satisfactory to Lender in its sole discretion, and all information relating
thereto requested by Lender is delivered to Lender at least 30 days prior to the
proposed transfer, (iii) Lender has obtained such estoppels from any guarantors
of the Note or replacement guarantors and such other legal opinions, Securities
and similar matters as Lender may require, (iv) all of Lender's costs and
expenses associated with the sale or transfer (including reasonable attorneys'
fees) are paid by Borrower or the grantee or transferee, (v) the payment of a
transfer fee not to exceed 1% of the then unpaid principal balance of the loan
evidenced by the Note and secured hereby (the "Loan"), (vi) the execution and
delivery to Lender of a written assumption agreement and substitute guaranty (in
its sole and absolute discretion) and such modifications to the Loan Documents
executed by such parties and containing such terms and conditions as Lender may
require in its sole and absolute discretion prior to such sale or transfer
(provided that in the event the Loan is included in a REMIC and is a performing
Loan, no modification to the terms and conditions shall be made or permitted
that would cause (A) any adverse tax consequences to the REMIC or any holders of
any Mortgage-Backed Pass-Through Securities, (B) the Security Instrument to fail
to be a Qualifying Security Instrument under applicable federal law relating to
REMIC's, or (C) result in a taxation of the income from the Loan to the REMIC or
cause a loss of REMIC status), and (vii) the delivery to Lender of an
endorsement (at Borrower's sole cost and expense) to Lender's policy of title

created by this Security Instrument in form and substance acceptable to Lender
in its sole judgment.

                  (d)      Without limiting the foregoing, if Lender shall
consent to any such transfer, the written assumption agreement described in
Subsection 8.3(c)(vi) above shall provide for the release of Borrower and, if
approved by Lender, each Guarantor and Indemnitor of personal liability under
the Note and Other Loan Documents, but as to acts or events occurring, or
obligations arising, after the closing of such transfer.

         Section 8.4 - NO IMPLIED FUTURE CONSENT

                  Lender's consent to one sale, conveyance, alienation,
mortgage, encumbrance, pledge or transfer of the Property shall not be deemed to
be a waiver of Lender's right to require such consent to any future occurrence
of same. Any sale, conveyance, alienation, mortgage, encumbrance, pledge or
transfer of the Property made in contravention of this Article 8 shall be null
and void and of no force and effect.

         Section 8.5 - COSTS OF CONSENT

any such sale, conveyance, alienation, mortgage, encumbrance, pledge or
transfer.

alteration, improvement, demolition or removal of any of the Improvements
without the prior consent of Lender;

                  (i)      damage to the Property in any manner which is not

agent for the Property resigns or is removed, (ii) the ownership, management or

                  (k)      this Security Instrument shall cease to constitute a
first-priority lien on the Property (other than in accordance with its terms);

                  (1)      seizure or forfeiture of the Property, or any portion

         Section 9.2 - DEFAULT INTEREST

                  Borrower will pay, from the date of an Event of Default

balance of the Note at a per annum rate equal to the lesser of (a) the greater
of (i) five percent (5%) plus the Prime Rate (as defined in the Note), and (ii)
five percent (5%) plus the Applicable Interest Rate (as defined in the Note),
and (b) the maximum interest rate which Borrower may by law pay or Lender may
charge and collect (the "Default Rate").

                        ARTICLE 10 - RIGHTS AND REMEDIES

         Section 10.1 - REMEDIES

                  Upon the occurrence of any Event of Default, Borrower agrees
that Lender may take such action, by or through Trustee, by Lender itself or
otherwise, without notice or demand, as it deems advisable to protect and
enforce its rights against Borrower and in and to the Property, including, but
not limited to, the following actions, each of which may be pursued concurrently
or otherwise, at such time and in such order as Lender may determine, in its
sole discretion, without impairing or otherwise affecting the other rights and
remedies of Lender:

                  (a)      Right to Perform Borrower's Covenants. If Borrower
has failed to keep or perform any covenant whatsoever contained in this Security
Instrument or the Other Loan Documents, Lender may, but shall not be obligated
to any person to do so, perform or attempt to perform said covenant and any
payment made or expense incurred in the performance or attempted performance of
any such covenant, together with any sum expended by Lender that is chargeable
to Borrower or subject to reimbursement by Borrower under the Loan Documents,
shall be and become a part of the "Debt", and Borrower promises, upon demand, to
pay to Lender, at the place where the Note is payable, all sums so incurred,
paid or expended by Lender, with interest from the date when paid, incurred or
expended by Lender at the Default Rate.

                  (b)      Right of Entry. Lender may, prior or subsequent to
the institution of any foreclosure proceedings, enter upon the Property, or any
part thereof, and take exclusive possession of the Property and of all books,
records, and accounts relating thereto and to exercise without interference from
Borrower any and all rights which Borrower has with respect to the management,
possession, operation, protection, or preservation of the Property, including
without limitation the right to rent the same for the account of Borrower and to
deduct from such Rents all costs, expenses, and liabilities of every character
incurred by Lender in collecting such Rents and in managing, operating,
maintaining, protecting, or preserving the Property and to apply the remainder
of such Rents on the Debt in such manner as Lender may elect. All such costs,
expenses, and liabilities incurred by Lender in collecting such Rents and in
managing, operating, maintaining, protecting, or preserving the Property, if not
paid out of Rents as hereinabove provided, shall constitute a demand obligation
owing by Borrower and shall bear interest from the date of expenditure until
paid at the Default Rate, all of which shall constitute a

portion of the Debt. If necessary to obtain the possession provided for above,
Lender may invoke any and all legal remedies to dispossess Borrower, including
specifically one or more actions for forcible entry and detainer, trespass to
try title, and restitution. In connection with any action taken by Lender
pursuant to this Subsection 10.l(b), Lender shall not be liable for any loss
sustained by Borrower resulting from any failure to let the Property, or any
part thereof, or from any other act or omission of Lender in managing the
Property unless such loss is caused by the willful misconduct of Lender, nor
shall Lender be obligated to perform or discharge any obligation, duty, or
liability under any Lease or under or by reason hereof or the exercise of rights
or remedies hereunder. Borrower shall and does hereby agree to indemnify Lender
for, and to hold Lender harmless from, any and all liability, loss, or damage,
which may or might be incurred by Lender under any such Lease or under or by
reason hereof or the exercise of rights or remedies hereunder, and from any and
all claims and demands whatsoever which may be asserted against Lender by reason
of any alleged obligations or undertakings on its part to perform or discharge
any of the terms, covenants, or agreements contained in any such Lease. Should
Lender incur any such liability, the amount thereof, including without
limitation costs, expenses, and reasonable attorneys' fees, together with
interest thereon from the date of expenditure until paid at the Default Rate,
shall be secured hereby, and Borrower shall reimburse Lender therefor
immediately upon demand. Nothing in this Subsection 10.1(b) shall impose any
duty, obligation, or responsibility upon Lender for the control, care,
management, leasing, or repair of the Property, nor for the carrying out of any
of the terms and conditions of any such Lease; nor shall it operate to make
Lender responsible or liable for any waste committed on the Property by the
tenants or by any other parties, or for any hazardous substances or
environmental conditions on or under the Property, or for any dangerous or
defective condition of the Property or for any negligence in the management,
leasing, upkeep, repair, or control of the Property resulting in loss or injury
or death to any tenant, licensee, employee, or stranger. Borrower hereby assents
to, ratifies, and confirms any and all actions of Lender with respect to the
Property taken under this subsection.

                  (c)      Right to Accelerate. Lender may, without notice
(except as provided in Section 9.1(p) above) demand, presentment, notice of
nonpayment or nonperformance, protest, notice of protest, notice of intent to
accelerate, notice of acceleration, or any other notice or any other action, all
of which are hereby waived by Borrower and ail other parties obligated in any
manner whatsoever on the Debt, declare the entire unpaid balance of the Debt
immediately due and payable, and upon such declaration, the entire unpaid
balance of the Debt shall be immediately due and payable.

                  (d)      Foreclosure-Power of Sale. Lender may institute a
proceeding or proceedings, judicial, or nonjudicial, by advertisement or
otherwise, for the complete or partial foreclosure of this Security Instrument
or the complete or partial sale of the Property under power of sale or under any
applicable provision of law. Lender may, through the Trustee, sell the Property,
and all estate, right, title, interest, claim and demand of Borrower therein,
and all rights of redemption thereof, at one or more sales, as an entirety or in
parcels, with such elements of real and/or personal property, and at such time
and place and upon such terms as it may deem expedient, or as may be required by
applicable law, and in the event of a sale, by foreclosure or otherwise, of less
than all of the Property, this Security Instrument shall continue as a lien and
security interest on the remaining portion of the Property.

                  (e)      Rights Pertaining to Sales. Subject to the
requirements of applicable law and except as otherwise provided herein, the
following provisions shall apply to any sale or sales of all or any portion of
the Property under or by virtue of Subsection 10.1(d) above, whether made under
the power of sale herein granted or by virtue of judicial proceedings or of a
judgment or decree of foreclosure and sale:

                           (i)      Trustee or Lender may conduct any number of
sales from time to time. The power of sale set forth above shall not be
exhausted by any one or more such sales as to any part of the Property which
shall not have been sold, nor by any sale which is not completed or is defective
in Lender's opinion, until the Debt shall have been paid in full.

                           (ii)     Any sale may be postponed or adjourned by
public announcement at the time and place appointed for such sale or for such
postponed or adjourned sale without further notice.

                           (iii)    After each sale, Lender, Trustee or an
officer of any court empowered to do so shall execute and deliver to the
purchaser or purchasers at such sale a good and sufficient instrument or
instruments granting, conveying, assigning and transferring all right, title and
interest of Borrower in and to the property and rights sold and shall receive
the proceeds of said sale or sales and apply the same as specified in the Note.
Each of Trustee and Lender is hereby appointed the true and lawful
attorney-in-fact of Borrower, which appointment is irrevocable and shall be
deemed to be coupled with an interest, in Borrower's name and stead, to make all
necessary conveyances, assignments, transfers and deliveries of the property and
rights so sold, Borrower hereby ratifying and confirming all that said attorney
or such substitute or substitutes shall lawfully do by virtue thereof.
Nevertheless, Borrower, if requested by Trustee or Lender, shall ratify and
confirm any such sale or, sales by executing and delivering to Trustee, Lender
or such purchaser or purchasers all such instruments as may be advisable, in
Trustee's or Lender's judgment, for the purposes as may be designated in such
request.

                           (iv)     Any and all statements of fact or other
recitals made in any of the instruments referred to in Subsection 10.1(e)(iii)
given by Trustee or Lender shall be taken as conclusive and binding against all
persons as to evidence of the truth of the facts so stated and recited.

                           (v)      Any such sale or sales shall operate to
divest all of the estate, right, title, interest, claim and demand whatsoever,
whether at law or in equity, of Borrower in and to the properties and rights so
sold, and shall be a perpetual bar both at law and in equity against Borrower
and any and all persons claiming or who may claim the same, or any part thereof
or any interest therein, by, through or under Borrower to the fullest extent
permitted by applicable law.

                           (vi)     Upon any such sale or sales, Lender may bid
for and acquire the Property and, in lieu of paying cash therefor, may make
settlement for the purchase price by crediting against the Debt the amount of
the bid made therefor, after deducting therefrom the expenses of the sale, the
cost of any enforcement proceeding hereunder, and any other sums

                                                   MORGAN GUARANTY TRUST COMPANY

                                       32

<PAGE>

which Trustee or Lender is authorized to deduct under the terms hereof, to the
extent necessary to satisfy such bid.

                           (vii)    Upon any such sale, it shall not be
necessary for Trustee, Lender or any public officer acting under execution or
order of court to have present or constructively in its possession any of the
Property.

                  (f)      Lender's Judicial Remedies. Lender, or Trustee upon
written request of Lender, may proceed by suit or suits, at law or in equity, to
enforce the payment of the Debt to foreclose the liens and security interests of
this Security Instrument as against all or any part of the Property, and to have
all or any part of the Property sold under the judgment or decree of a court of
competent jurisdiction. This remedy shall be cumulative of any other nonjudicial
remedies available to Lender under this Security Instrument, the Note or the
Other Loan Documents. Proceeding with a request or receiving a judgment for
legal relief shall not be or be deemed to be an election of remedies or bar any
available nonjudicial remedy of Lender.

                  (g)      Lender's Right to Appointment of Receiver. Lender, as
a matter of right and (i) without regard to the sufficiency of the security for
repayment of the Debt and without notice to Borrower, (ii) without any showing
of insolvency, fraud, or mismanagement on the part of Borrower, (iii) without
the necessity of filing any judicial or other proceeding other than the
proceeding for appointment of a receiver, and (iv) without regard to the then
value of the Property, shall be entitled to the appointment of a receiver or
receivers for the protection, possession, control, management and operation of
the Property, including (without limitation), the power to collect the Rents,
enforce this Security Instrument and, in case of a sale and deficiency, during
the full statutory period of redemption (if any), whether there be a redemption
or not, as well as during any further times when Borrower, except for the
intervention of such receiver, would be entitled to collection of such Rents.
Borrower hereby irrevocably consents to the appointment of a receiver or
receivers. Any receiver appointed pursuant to the provisions of this subsection
shall have the usual powers and duties of receivers in such matters.

                  (h)      Commercial Code Remedies. Lender may exercise any and
all rights and remedies granted to a secured party upon default under the
Uniform Commercial Code, including, without limiting the generality of the
foregoing: (i) the right to take possession of the Personal Property or any part
thereof, and to take such other measures as Lender may deem necessary for the
care, protection and preservation of the Personal Property, and (ii) request
Borrower at its expense to assemble the Personal Property and make it available
to Lender at a convenient place acceptable to Lender. Any notice of sale,
disposition or other intended action by Lender with respect to the Personal
Property sent to Borrower in accordance with the provisions hereof at least five
(5) days prior to such action, shall constitute commercially reasonable notice
to Borrower.

                  (i)      Apply Escrow Funds. Lender may apply any Funds (as
defined in the Escrow Agreement) and any other sums held in escrow or otherwise
by Lender in accordance with the terms of this Security Instrument or any Other
Loan Document to the payment of the following items in any order in its
uncontrolled discretion:

                                                   MORGAN GUARANTY TRUST COMPANY

                           (i)      Taxes and Other Charges;

                           (ii)     Insurance Premiums;

                           (iii)    Interest on the unpaid principal balance of
the Note;

                           (iv)     Amortization of the unpaid principal balance
of the Note; and

                           (v)      All other sums payable pursuant to the Note,
this Security Instrument and the Other Loan Documents, including without
limitation advances made by Lender pursuant to the terms of this Security
Instrument.

                  (j)      Other Rights. Lender (i) may surrender the Policies
maintained pursuant to this Security Instrument or any part thereof, and upon
receipt shall apply the unearned premiums as a credit on the Debt, and, in
connection therewith, Borrower hereby appoints Lender as agent and
attorney-in-fact (which is coupled with an interest and is therefore
irrevocable) for Borrower to collect such premiums; and (ii) may apply the Tax
and Insurance Escrow Fund (as defined in the Escrow Agreement) and/or the
Replacement Escrow Fund (as defined in the Escrow Agreement) and any other funds
held by Lender toward payment of the Debt; and (iii) shall have and may exercise
any and all other rights and remedies which Lender may have at law or in equity,
or by virtue of any of the Loan Documents, or otherwise.

                  (k)      Discontinuance of Remedies. In case Lender shall have
proceeded to invoke any right, remedy, or recourse permitted under the Loan
Documents and shall thereafter elect to discontinue or abandon same for any
reason, Lender shall have the unqualified right so to do and, in such event,
Borrower and Lender shall be 'restored to their former positions with respect to
the Debt, the Loan Documents, the Property or otherwise, and the rights,
remedies, recourses and powers of Lender shall continue as if same had never
been invoked.

                  (1)      Remedies Cumulative. All rights, remedies, and
recourses of Lender granted in the Note, this Security Instrument and the Other
Loan Documents, any other pledge of collateral, or otherwise available at law or
equity: (i) shall be cumulative and concurrent; (ii) may be pursued separately,
successively, or concurrently against Borrower, the Property, or any one or more
of them, at the sole discretion of Lender; (iii) may be exercised as often as
occasion therefor shall arise, it being agreed by Borrower that the exercise or
failure to exercise any of same shall in no event be construed as a waiver or
release thereof or of any other right, remedy, or recourse; (iv) shall be
nonexclusive; (v) shall not be conditioned upon Lender exercising or pursuing
any remedy in relation to the Property prior to Lender bringing suit to recover
the Debt; and (vi) in the event Lender elects to bring suit on the Debt and
obtains a judgment against Borrower prior to exercising any remedies in relation
to the Property, all liens and security interests, including the lien of this
Security Instrument, shall remain in full force and effect and may be exercised
thereafter at Lender's option.

                  (m)      Bankruptcy Acknowledgment. In the event the Property
or any portion thereof or any interest therein becomes property of any
bankruptcy estate or subject to any state or federal insolvency proceeding, then
Lender shall immediately become entitled, in addition to

all other relief to which Lender may be entitled under this Security Instrument,
to obtain (i) an order from the Bankruptcy Court or other appropriate court
granting immediate relief from the automatic stay pursuant to Section 362 of the
Bankruptcy Code so to permit Lender to pursue its rights and remedies against
Borrower as provided under this Security Instrument and all other rights and
remedies of Lender at law and in equity under applicable state law, and (ii) an
order from the Bankruptcy Court prohibiting Borrower's use of all "cash
collateral" as defined under Section 363 of the Bankruptcy Code. In connection
with such Bankruptcy Court orders, Borrower shall not contend or allege in any
pleading or petition filed in any court proceeding that Lender does not have
sufficient grounds for relief from the automatic stay. Any bankruptcy petition
or other action taken by the Borrower to stay, condition, or inhibit Lender from
exercising its remedies are hereby admitted by Borrower to be in bad faith and
Borrower further admits that Lender would have just cause for relief from the
automatic stay in order to take such actions authorized under state law.

                  (n)      Application of Proceeds. The proceeds from any sale,
lease, or other disposition made pursuant to this Security Instrument, or the
proceeds from the surrender of any insurance policies pursuant hereto, or any
Rents collected by Lender from the Property, or the Tax and Insurance Escrow
Fund or the Replacement Escrow Fund (as defined in the Escrow Agreement) or
proceeds from insurance which Lender elects to apply to the Debt pursuant to
Article 3 hereof, shall-be applied by Trustee, or by Lender, as the case may be,
to the Debt in the following order and priority: (1) to the payment of all
expenses of advertising, selling, and conveying the Property or part thereof,
and/or prosecuting or otherwise collecting Rents, proceeds, premiums or other
sums including reasonable attorneys' fees and a reasonable fee or commission to
Trustee, not to exceed five percent of the proceeds thereof or sums so received;
(2) to that portion, if any, of the Debt with respect to which no person or
entity has personal or entity liability for payment (the "Exculpated Portion"),
and with respect to the Exculpated Portion as follows: first, to accrued but
unpaid interest, second, to matured principal, and third, to unmatured principal
in inverse order of maturity; (3) to the remainder of the Debt as follows:
first, to the remaining accrued but unpaid interest, second, to the matured
portion of principal of the Debt, and third, to prepayment of the unmatured
portion, if any, of principal of the Debt applied to installments of principal
in inverse order of maturity; (4) the balance, if any or to the extent
applicable, remaining after the full and final payment of the Debt to the holder
or beneficiary of any inferior liens covering the Property, if any, in order of
the priority of such inferior liens (Trustee and Lender shall hereby be entitled
to rely exclusively on a commitment for title insurance issued to determine such
priority); and (5) the cash balance, if any, to the Borrower. The application of
proceeds of sale or other proceeds as otherwise provided herein shall be deemed
to be a payment of the Debt like any other payment. The balance of the Debt
remaining unpaid, if any, shall remain fully due and owing in accordance with
the terms of the Note and the other Loan Documents.

                  (a)      Borrower shall indemnify, defend and hold Lender and
Trustee harmless against: (i) any and all claims for brokerage, leasing,
finder's or similar fees which may be made relating to the Property or the Debt,
and (ii) any and all liability, obligations, losses, damages, penalties, claims,
actions, suits, costs and expenses (including Lender's reasonable attorneys'
fees, together with reasonable appellate counsel fees, if any) of whatever kind
or nature which may be asserted against, imposed on or incurred by Lender or
Trustee in connection with the Debt, this Security Instrument, the Property, or
any part thereof, or the exercise by Lender or Trustee of any rights or remedies
granted to it under this Security Instrument; provided, however, that nothing
herein shall be construed to obligate Borrower to indemnify, defend and hold
harmless Lender from and against any and all liabilities, obligations, losses,
damages, penalties, claims, actions, suits, costs and expenses enacted against,
imposed on or incurred by Lender by reason of Lender's willful misconduct or
gross negligence.

                  (b)      If Lender is made a party defendant to any litigation
or any claim is threatened or brought against Lender concerning the secured
indebtedness, this Security Instrument, the Property, or any part thereof, or
any interest therein, or the construction, maintenance, operation or occupancy
or use thereof, then Lender shall notify Borrower of such litigation or claim
and Borrower shall indemnify, defend and hold Lender harmless from and against
all liability by reason of said litigation or claims, including reasonable
attorneys' fees (together with reasonable appellate counsel fees, if any). The
right to such attorneys' fees (together with reasonable appellate counsel fees,
if any) and expenses incurred by Lender in any such litigation or claim of the
type described in this Subsection 11.1 (b), whether or not any such litigation
or claim is prosecuted to judgment, shall be deemed to have accrued on the
commencement of such claim or action and shall be enforceable whether or not
such claim or action is prosecuted to judgment. If Lender commences an action
against Borrower to enforce any of the terms hereof or to prosecute any breach
by Borrower of any of the terms hereof or to recover any sum secured hereby.
Borrower shall pay to Lender its reasonable attorneys' fees (together with
reasonable appellate counsel fees, if any) and expenses. If Borrower breaches
any term of this Security Instrument, Lender may engage the services of an
attorney or attorneys to protect its rights hereunder, and in the event of such
engagement following any breach by Borrower, Borrower shall pay Lender
reasonable attorneys' fees (together with reasonable appellate counsel fees, if
any) and expenses incurred by Lender, whether or not an action is actually
commenced against Borrower by reason of such breach. All references to
"attorneys" in this Subsection 11.1 (b) and elsewhere in this Security
Instrument shall include without limitation any attorney or law firm engaged by
Lender and Lender's in-house counsel, and all references to "fees and expenses"
in this Subsection 11.l(b) and elsewhere in this Security Instrument shall
include without limitation any fees of such attorney or law firm and any
allocation charges and allocation costs of Lender's in-house counsel.

                  (c)      A waiver of subrogation shall be obtained by Borrower
from its insurance carrier and, consequently, Borrower waives any and all right
to claim or recover against Lender, its officers, employees, agents and
representatives, for loss of or damage to Borrower, the

                        ARTICLE 12 - SECURITY AGREEMENT

         Section 12.1 - SECURITY AGREEMENT

                  This Security Instrument is both a real property mortgage and
a "security agreement" within the meaning of the Uniform Commercial Code. The
Property includes both real and personal property and all other rights and
interests, whether tangible or intangible in nature, of Borrower in the
Property. Borrower by executing and delivering this Security Instrument has
granted and hereby grants to Lender, as security for the Obligations, a security
interest in the Property to the full extent that the Property may be subject to
the Uniform Commercial Code (said portion of the Property so subject to the
Uniform Commercial Code being called in this paragraph the "Collateral").
Borrower hereby agrees with Lender to execute and deliver to Lender, in form and
substance satisfactory to Lender, such financing statements, continuation
statements, other uniform commercial code forms and shall pay all expenses and
fees in connection with the filing and recording thereof, and such further
assurances as Lender may from time to time, reasonably consider necessary to
create, perfect, and preserve Lender's security interest herein granted. This
Security Instrument shall also constitute a "fixture filing" for the purposes of
the Uniform Commercial Code. All or part of the Property are or are to become
fixtures. Information concerning the security interest herein granted may be
obtained from the parties at the addresses of the parties set forth in the first
paragraph of this Security Instrument. If an Event of Default shall occur,
Lender, in addition to any other rights and remedies which they may have, shall
have and may exercise immediately and without demand, any and all rights and
remedies granted to a secured party upon default under the Uniform Commercial
Code, including, without limiting the generality of the foregoing, the right to
take possession of the Collateral or any part thereof, and to take such other
measures as Lender may deem necessary for the care, protection and preservation
of the Collateral. Upon request or demand of Lender, Borrower shall at its
expense assemble the Collateral and make it available to Lender at a convenient
place acceptable to Lender. Borrower shall pay to Lender on demand any and all
expenses, including legal expenses and attorneys' fees, incurred or paid by
Lender in protecting the interest in the Collateral and in enforcing the rights
hereunder with respect to the Collateral. Any notice of sale, disposition or
other intended action by Lender with respect to the Collateral sent to Borrower
in accordance with the provisions hereof at least five (5) days prior to

                                                   MORGAN GUARANTY TRUST COMPANY

                                       40

<PAGE>

such action, shall constitute commercially reasonable notice to Borrower. The
proceeds of any disposition of the Collateral, or any part thereof, may be
applied by Lender to the payment of the Obligations in such priority and
proportions as Lender in its discretion shall deem proper. In the event of any
change in name, identity or structure of any Borrower, such Borrower shall
notify Lender thereof, and promptly after request shall execute, file and record
such Uniform Commercial Code forms as are necessary to maintain the priority of
Lender's lien upon and security interest in the Collateral, and shall pay all
expenses and fees in connection with the filing and recording thereof. If Lender
shall require the filing or recording of additional Uniform Commercial Code
forms or continuation statements, Borrower shall, promptly after request,
execute, file and record such Uniform Commercial Code forms or continuation
statements as Lender shall deem necessary, and shall pay all expenses and fees
in connection with the filing and recording thereof it being understood and
agreed, however, that no such additional documents shall increase Borrower's
obligations under the Note, this Security Instrument and the Other Loan
Documents. Borrower hereby irrevocably appoints Lender as its attorney-in-fact,
coupled with an interest, to file with the appropriate public office on its
behalf any financing or other statements signed only by Lender, as Borrower's
attorney-in-fact, in connection with the Collateral covered by this Security
Instrument. Notwithstanding the foregoing, Borrower shall appear and defend in
any action or proceeding which affects or purports to affect the Property and
any interest or right therein, whether such proceeding effects title or any
other rights in the Property (and in conjunction therewith, Borrower shall fully
cooperate with Lender in the event Lender is a party to such action or
proceeding).

benefit of all appraisement, valuation, stay, extension, reinstatement and
redemption laws now or hereafter in force and all rights of marshalling in the
event of any sale hereunder of the Property or any part thereof or any interest
therein. Further, Borrower hereby expressly waives any and all rights of
redemption from sale under any order or decree of foreclosure of this Security
Instrument on behalf of Borrower, and on behalf of each and every person
acquiring any interest in or title to the Property subsequent to the date of
this Security Instrument and on behalf of all persons to the extent permitted by
applicable law.

         Section 14.2 - WAIVER OF NOTICE

                  Borrower shall not be entitled to any notices of any nature
whatsoever from Lender except with respect to matters for which this Security
Instrument specifically and expressly provides for the giving of notice by
Lender to Borrower and except with respect to matters for which Lender is
required by applicable law to give notice, and Borrower hereby expressly waives
the right to receive any notice from Lender with respect to any matter for which
this Security Instrument does not specifically and expressly provide for the
giving of notice by Lender to Borrower.

         Section 14.3 - SOLE DISCRETION OF LENDER

                  Wherever pursuant to this Security Instrument Lender exercises
any right given to it to approve or disapprove, or any arrangement or term is to
be satisfactory to Lender, the decision of Lender to approve or disapprove or to
decide that arrangements or terms are satisfactory or not satisfactory shall be
in the sole discretion of Lender and shall be final and conclusive, except as
may be otherwise expressly and specifically provided herein.

         Section 14.4 - SURVIVAL

                  The indemnifications made pursuant to Article 11, shall
continue indefinitely in full force and effect and shall survive and shall in no
way be impaired by: any satisfaction or other termination of this Security
Instrument, any assignment or other transfer of all or any portion of this
Security Instrument or Lender's interest in the Property (but, in such case,
shall benefit both Indemnified Parties and any assignee or transferee), any
exercise of Lender's rights and remedies pursuant hereto including but not
limited to foreclosure or acceptance of a deed in lieu of foreclosure, any
exercise of any rights and remedies pursuant to the Note or any of the Other
Loan Documents, any transfer of all or any portion of the Property (whether by
Borrower or by Lender following foreclosure or acceptance of a deed in lieu of
foreclosure or at any other time), any amendment to this Security Instrument,
the Note or the Other Loan Documents, and any act or omission that might
otherwise be construed as a release or discharge of Borrower from the
obligations pursuant hereto.

         Section 14.5 - WAIVER OF TRIAL BY JURY

                  BORROWER HEREBY AGREES NOT TO ELECT A TRIAL BY JURY OF ANY
ISSUE TRIABLE OF RIGHT BY JURY, AND WAIVES ANY RIGHT TO TRIAL BY JURY FULLY TO
THE EXTENT THAT ANY SUCH RIGHT SHALL NOW OR HEREAFTER EXIST WITH REGARD TO THIS
SECURITY INSTRUMENT, THE NOTE OR THE OTHER LOAN DOCUMENTS, OR ANY CLAM,
COUNTERCLAIM OR OTHER ACTION ARISING IN CONNECTION THEREWITH INCLUDING, BUT NOT
LIMITED TO THOSE RELATING TO (A) ALLEGATIONS THAT A PARTNERSHIP EXISTS BETWEEN
LENDER AND BORROWER; (B) USURY OR PENALTIES OR DAMAGES THEREFOR; (C) ALLEGATIONS

HEREBY AUTHORIZED TO FILE A COPY OF THIS PARAGRAPH IN ANY PROCEEDING AS
CONCLUSIVE EVIDENCE OF THIS WAIVER BY BORROWER.

         Section 14.6 - WAIVER OF AUTOMATIC OR SUPPLEMENTAL STAY

                  In the event of the filing of any voluntary or involuntary
petition under the Bankruptcy Code by or against Borrower (other than an
involuntary petition filed by or joined in by Lender), the Borrower shall not
assert, or request any other party to assert, that the automatic stay under
Section 362 of the Bankruptcy Code shall operate or be interpreted to stay,
interdict, condition, reduce or inhibit the ability of Lender to enforce any
rights it has by virtue of this Security Instrument, or any other rights that
Lender has, whether now or hereafter acquired, against any guarantor of the
Debt. Further, Borrower shall not seek a supplemental stay or any other relief,
whether injunctive or otherwise, pursuant to Section 105 of the Bankruptcy Code
or any other provision therein to stay, interdict, condition, reduce or inhibit
the ability of Lender to enforce any rights it has by virtue of this Security
Instrument against any guarantor of the Debt. The waivers contained in this
paragraph are a material inducement to Lender's willingness to enter into this
Security Instrument and Borrower acknowledges and agrees that no grounds exist
for equitable relief which would bar, delay or impede the exercise by Lender of
Lender's rights and remedies against Borrower or any guarantor of the Debt.

                  This Security Instrument shall be governed by and construed in
accordance with applicable federal law and the laws of the Commonwealth of
Virginia, without reference or giving effect to any choice of law doctrine.
Borrower hereby irrevocably submits to the jurisdiction of any court of
competent jurisdiction located in the Commonwealth of Virginia in connection

         Section 16.2 - USURY LAWS

                  This Security Instrument and the Note are subject to the
express condition that at no time shall Borrower be obligated or required to pay
interest on the Debt at a rate which could subject the holder of the Note 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 Security Instrument or the Note, Borrower is at
any time required or obligated to pay interest on the Debt at a rate in excess
of such maximum rate, the rate of interest under the Security Instrument and the
Note shall be deemed to be immediately reduced to such maximum rate and the
interest payable shall be computed at such maximum rate and all prior interest
payments in excess of such maximum rate shall be applied and shall be deemed to

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.

the provisions of any applicable law. If any term of this Security Instrument or
any application thereof shall be invalid or unenforceable, the remainder of this
Security Instrument and any other application of the term shall not be affected
thereby.

trustees, to act instead of the aforenamed Trustee, Lender shall have full power
to appoint a substitute trustee (or, if preferred, multiple substitute trustees)
in succession who shall succeed (and if multiple substitute trustees are

corporation and such appointment be executed in its behalf by any officer of
such corporation, such appointment shall be conclusively presumed to be executed
with authority and shall be valid and sufficient without proof of any action by

pursuant to this Security Instrument or applicable law. Any substitute Trustee
appointed pursuant to any of the provisions hereof shall, without any further
act. deed, or conveyance, become vested with all the estates, properties,
rights, powers, and trusts of its or his predecessor in the rights hereunder
with like effect as if originally named as Trustee herein; but nevertheless,
upon the written request of Lender or of the substitute Trustee, the Trustee
ceasing to act shall execute and deliver any instrument transferring to such
substitute Trustee, upon the trusts herein expressed, all the estates,
properties, rights, powers, and trusts of the Trustee so ceasing to act, and
shall duly assign, transfer and deliver any of the property and moneys held by
such Trustee to the substitute Trustee so appointed in the Trustee's place. No
fees or expenses shall be payable to Trustee, except in connection with a
foreclosure of the Property or any part thereof or in connection with the
release of the Property following payment in full of the Debt.
