                        Curable Property Default with respect to an Individual
                        Property to be released from the Lien of the related

                        issue two substitute notes, one note having a principal

2.6.2.  Interest on the Loan shall be paid in arrears in monthly installments
-----                                                                        
(the amount of each such installment, the "MONTHLY DEBT SERVICE PAYMENT AMOUNT")
                                           -----------------------------------  
on the tenth day of each calendar month up to and including the tenth day of

occurrence of the Default in the payment of principal, interest or other sums
due under the Loan Documents or the Event of Default until the actual receipt
and collection of the Debt (or that portion thereof that is then due) or the
cure of any other Event of Default.  Interest at the Default Rate, to the extent
permitted by applicable law, shall be added to the Debt and shall be secured by
the Mortgages.  This subsection, 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.

          SECTION 2.6  PAYMENTS AND COMPUTATIONS.

Borrower shall be computed on the basis of the actual number of days elapsed in
a 360-day year.

          2.6.3  INTENTIONALLY OMITTED

          2.6.4  PAYMENTS AFTER ANTICIPATED REPAYMENT DATE. (a)  For the partial
                 -----------------------------------------                      
year period commencing on the Anticipated Repayment Date, and for each Fiscal
Year thereafter, the Borrower shall submit to Lender for Lender's written
approval the Annual Budget not later than thirty (30) days prior to the
commencement of such period or Fiscal Year.  Such Annual Budget shall be in form
and substance reasonably satisfactory to Lender setting forth in reasonable
detail budgeted monthly operating income and monthly operating capital and
monthly operating and other expenses for the Properties, including all planned
capital expenditures in respect of the Properties for such period or Fiscal
Year. Each such 

                                      -23-
<PAGE>
 
Annual Budget approved by Lender shall hereinafter be referred to as an
"APPROVED ANNUAL BUDGET". Until such time that Lender approves a proposed Annual
 ----------------------
Budget, the most recently Approved Annual Budget shall apply; provided that,
such Approved Annual Budget shall be adjusted to reflect actual increases in
real estate taxes, insurance premiums and utilities expenses.

                 (b) In the event that, after the Anticipated Repayment Date,
the Borrower must incur an extraordinary operating expense or capital expense
not set forth in the Annual Budget (each an "EXTRAORDINARY EXPENSE"), then the

Borrower shall promptly deliver to Lender a reasonably detailed explanation of
such proposed Extraordinary Expense for the Lender's approval.

                 (c) From and after the Anticipated Repayment Date, interest
shall accrue on the unpaid principal balance from time to time outstanding on
the Note at the Matured Performing Rate. Borrower shall continue to make
payments of interest in monthly installments beginning on the Anticipated
Repayment Date and on the tenth day of each calendar month thereafter up to and
including the Maturity Date in an amount equal to the Monthly Debt Service
Payment Amount and, notwithstanding the following provision with respect to
Accrued Interest, the failure to make any such payment as and when due shall
constitute an Event of Default. Each Monthly Debt Service Payment Amount paid
after the Anticipated Repayment Date shall be applied to the payment of interest
computed at the Regular Interest Rate. Interest accrued at the Matured
Performing Rate and not paid pursuant to the preceding sentence shall be
deferred and added to the Debt and shall earn interest at the Matured Performing
Rate to the extent permitted by applicable law (such accrued interest is
hereinafter defined as "ACCRUED INTEREST"). In addition to such payments of
                        ----------------
interest, from and after th Anticipated Repayment Date, Borrower shall make
payments in reduction of the outstanding principal balance of the Loan in
monthly installments beginning on the Anticipated Repayment Date and on the
tenth day of each calendar month thereafter up to and including the Maturity
Date in an amount equal to the Excess Cash Flow for the immediately preceding
calendar month. All of the Debt, including any Accrued Interest, shall be due
and payable on the Maturity Date.

          2.6.5  PAYMENTS RECEIVED IN THE CASH COLLATERAL ACCOUNT.
                 ------------------------------------------------  
Notwithstanding anything to the contrary contained in this Agreement or the
other Loan Documents, and provided no Event of Default has occurred and is
continuing, Borrower's obligations with respect to the monthly payment of
principal and interest and amounts due for the Tax and Insurance Escrow Fund,
the Ground Lease Escrow Fund and any other payment reserves established pursuant
to this Agreement or any other Loan Document shall be deemed satisfied to the
extent sufficient amounts are deposited in the Cash Collateral Account to
satisfy such obligations on the dates each such payment is required, regardless
of whether any of such amounts are so applied by Lender.

that (a) the Substitution Conditions are satisfied with respect to Substitute
Properties other than a Substituted Property damaged by a casualty or affected

                 and assumption of lessee's interest in the Ground Lease
                 (together with the ground lessor's consent thereto), as
                 applicable, conveying all of Borrower's right, title and
                 interest in and to the Substituted Property to an entity other
                 than Borrower and a letter from Borrower countersigned by a

          (ii)   Lender shall have received an appraisal of the Substitute
                 Property dated no more than sixty (60) days prior to the
                 substitution by an appraiser acceptable to the Rating Agencies,
                 indicating an appraised value of the Substitute Property that
                 is equal to or greater than the value of the Substituted
                 Property determined by Lender at the time of the encumbrance of
                 the Substituted Property by the related Mortgage in connection
                 with the Initial Advance or a Subsequent Advance, as
                 applicable.

          (iii)  After giving effect to the substitution, the Debt Service
                 Coverage Ratio for the Loan for all of the Properties is not
                 less than the Debt Service Coverage Ratio for the Loan for all
                 of the Properties as of the Outside Closing Date and as of the
                 date immediately preceding the substitution.

          (iv)   The Net Operating Income for the Substitute Property does not
                 show a downward trend over the three (3) years immediately
                 prior to the date of substitution or, with respect to a
                 Substitute Property for which information regarding the Net
                 Operating Income of such Substitute Property for the three (3)
                 years immediately prior to the date of substitution cannot be
                 obtained by Borrower after Borrower's exercise of diligent
                 efforts, the Net Operating Income shall not show a downward
                 trend for such period of time immediately prior to the date of
                 substitution as

                 may be determined from the information regarding such Net
                 Operating Income available.

          (v)    The Net Operating Income and Debt Service Coverage Ratio (for
                 the twelve (12) month period immediately preceding the
                 substitution) for the Substitute Property is greater than one
                 hundred twenty-five percent (125%) of the Net Operating Income
                 and Debt Service Coverage Ratio (for the twelve (12) month
                 period immediately preceding the substitution) for the related

                 Service Coverage Ratio with respect to a Substitute Property or
                 a Substituted Property shall be calculated using the Net
                 Operating Income with respect to such Substitute Property or
                 the Substituted Property, as applicable, and the principal and
                 interest due and payable on the Note with respect to the
                 related Pro rata Substitute Release Amount or Pro rata Release
                 Amount, as applicable.

          (vi)   Lender shall have received evidence in writing from the Rating
                 Agencies to the effect that such substitution will not result
                 in a withdrawal, qualification or downgrade of the respective
                 ratings in effect immediately prior to such substitution for
                 the Securities issued in connection with the Securitization
                 that are then outstanding.

          (vii)  No Default or Event of Default shall have occurred and be
                 continuing and Borrower shall be in compliance in all material
                 respects with all terms and conditions set forth in this
                 Agreement and in each Loan Document on Borrower's part to be
                 observed or performed. Lender shall have received a certificate
                 from Borrower confirming the foregoing, stating that the
                 representations and warranties of Borrower contained in this
                 Agreement and the other Loan Documents are true and correct in
                 all material respects on and as of the date of the substitution
                 with respect to Borrower, the Properties and the Substitute
                 Property and containing any other representations and
                 warranties with respect to Borrower, the Properties, the
                 Substitute Property or the Loan as the Rating Agencies may
                 require, unless such certificate would be inaccurate, such
                 certificate to be in form and substance satisfactory to the
                 Rating Agencies.

                 the same content as the certification of the Survey of the
                 Substituted Property prepared by a professional land surveyor

                 other things, a metes and bounds description of the real

                 shall certify that the surveyed property is not located in a
                 "one-hundred-year flood hazard area."

                 Substance, such report shall include an estimate of the cost of

                 Property is located stating that the Loan Documents delivered
                 with respect to the Substitute Property pursuant to clause
                 (viii) above are valid and enforceable in accordance with their
                 terms, subject to the laws applicable to creditors' rights and
                 equitable principles, and that Borrower is qualified to do
                 business and in good standing under the laws of the
                 jurisdiction where the Substitute Property is located or that

                                      -29-
<PAGE>
 
                 delivery of such Loan Documents and the performance by Borrower
                 of its obligations thereunder will not cause a breach of, or a

                 the related Mortgage and the execution and delivery of the
                 related Loan Documents does not and will not affect or impair
                 the ability of Lender to enforce its remedies under all of the
                 Loan Documents or to realize the benefits of the cross-
                 collateralization provided for thereunder; (D) an update of the

                 counsel acceptable to the Rating Agencies stating that the
                 substitution and the related transactions do not constitute a

                 insolvency laws and (F) an opinion of counsel acceptable to the
                 Rating Agencies that the substitution does not constitute a

                 the Code or otherwise cause a tax to be imposed on a

such consent is required, it has been obtained prior to the Closing Date).

               (iv) DEFAULT. As of the Closing Date, the Ground Lease is in full
force and effect and, to the best of Borrower's knowledge, no default has
occurred under the Ground Lease and there is no existing condition which, but
for the passage of time or the giving of notice, could result in a default under
the terms of the Ground Lease.

               (v) NOTICE. The Ground Lease requires the Landlord thereunder to
give notice of any default by the Borrower to the Lender. The Ground Lease, or
an estoppel letter received by the Lender from the Landlord, further provides
that notice of termination given under the Ground Lease is not effective against
the Lender unless a copy of the notice has been delivered to the Lender in the
manner described in the Ground Lease.

               (vi) CURE. The Lender is permitted the opportunity (including,
where necessary, sufficient time to gain possession of the interest of the
Borrower under the Ground Lease) to cure any default under the Ground Lease,
which is curable after the receipt of notice of any default before the Landlord
thereunder may terminate the Ground Lease.

               (vii) TERM. The Ground Lease has a term which extends not less
than ten (10) years beyond the Maturity Date of the Loan.

               (viii) NEW LEASE. The Ground Lease requires the Landlord to enter
into a new lease upon termination of the Ground Lease for any reason, including
rejection of the Ground Lease in a bankruptcy proceeding.

               (ix) INSURANCE PROCEEDS. Under the terms of the Ground Lease and
the related Mortgage, taken together, any related insurance and condemnation
proceeds will be held by Lender and applied either to the repair or restoration
of the applicable Individual Property or to the payment of the Debt in
accordance with the Loan Documents. In the event that insurance proceeds exceed
One Hundred Thousand and No/100 Dollars ($100,000) and are not otherwise
required to be paid to Lender pursuant to the Loan Documents, such insurance
proceeds will be paid to the Landlord and Borrower in escrow in an interest-
bearing account and applied to the repair or restoration of the applicable
Individual Property.

covenants and agreements made in this Agreement or in the other Loan Documents
by Borrower shall be deemed to have been relied upon by Lender notwithstanding
any investigation heretofore or hereafter made by Lender or on its behalf.

          V.    AFFIRMATIVE COVENANTS
                ---------------------

          SECTION 5.1  BORROWER COVENANTS.
                       ------------------ 

          From the date hereof and until payment and performance in full of all
obligations of Borrower under the Loan Documents or the earlier release of the
Liens of all Mortgages encumbering the Properties (and all related obligations)
in accordance with the terms of this Agreement and the other Loan Documents,
Borrower hereby covenants and agrees with Lender that:

          (a) Existence; Compliance with Legal Requirements; Insurance.
              --------------------------------------------------------  
Borrower shall do or cause to be done all things necessary to preserve, renew
and keep in full force and effect its partnership existence, rights, licenses,
permits and franchises and comply in all material respects with all Legal
Requirements applicable to it and the Properties (except for those Legal
Requirements being contested by Borrower in accordance with this Agreement and
other Loan Documents).  Borrower shall at all times maintain, preserve and
protect all of its material property used in the conduct of its business and
shall keep all of the Properties in good working order and repair (except for
ordinary wear and tear and damage from a casualty or condemnation pending any
required restoration thereof), and from time to time make, or cause to be made,
all reasonably necessary repairs, renewals, replacements, betterments and
improvements thereto, all as more fully provided in the Mortgages encumbering
such Properties.  Borrower shall keep each of the Properties insured at all
times by financially sound and reputable insurers, to such extent and against
such risks, and maintain liability and such other insurance, as is more fully
provided in this Agreement.

          (b) Taxes and Other Charges.  Borrower shall pay all Taxes and Other
              -----------------------                                         
Charges now or hereafter levied or assessed or imposed against the Properties or
any part thereof prior to delinquency or the imposition of any fine or penalty;
provided, however, Borrower's obligation to directly pay Taxes shall be
suspended for so long as Borrower complies with the terms and provisions of
                                                                           
Section 7.3 hereof.  Borrower shall not suffer and shall promptly cause to be
-----------                                                                  
paid and discharged any lien or charge whatsoever which may be or become a lien
or charge against any of the Properties (subject to Borrower's right to contest
Taxes and Other Charges in accordance with this Section 5.1(b)), and shall
                                                ---------------           
promptly pay for all utility services provided to the Properties.  Borrower
shall furnish to Lender receipts for 

                                      -55-
<PAGE>
 
the payment of the Taxes and the Other Charges prior to the date the same shall
become delinquent (provided, however, that Borrower is not required to furnish
such receipts for payment of Taxes in the event that such Taxes have been paid
by Lender pursuant to Section 7.3 hereof). 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 Taxes or Other
Charges, provided that (i) no Event of Default has occurred and remains uncured,
(ii) Borrower is permitted to do so under the provisions of any mortgage or deed
of trust affecting any of the Properties, (iii) 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 and such proceeding shall be conducted in accordance with all
applicable statutes, laws and ordinances, (iv) no Individual Property nor any
part thereof or interest therein will be in danger of being sold, forfeited,
terminated, canceled or lost, and (v) Borrower shall promptly upon final
determination thereof pay the amount of any such Taxes or Other Charges,
together with all costs, interest and penalties which may be payable in
connection therewith. In addition, if the Taxes or Other Charges are not paid in
full when the Borrower commences such contest, then the following shall apply:
(A) such proceeding shall suspend the collection of Taxes or Other Charges from
the applicable Individual Property, and (B) Borrower shall have furnished such
security as may be required in the proceeding, or as may be reasonably requested
by Lender or sufficient funds are on deposit in the Tax and Insurance Escrow
Fund to pay any such Taxes or Other Charges pursuant to Section 7.3, to insure
                                                        -----------
the payment of any such Taxes or Other Charges, together with all interest and
penalties thereon. Lender may pay over any such cash deposit or part thereof
held by Lender to the claimant entitled thereto at any time when, in the
reasonable judgment of Lender, the entitlement of such claimant is established
after Borrower's appeals have been exhausted.

          (c) Litigation.  Borrower shall give prompt written notice to Lender
              ----------

Borrower which might materially adversely affect Borrower's financial condition
or business or any of the Properties.

than as permitted pursuant to this Agreement, the Environmental Indemnity and
the other Loan Documents) any of the Properties or any part thereof at
reasonable hours upon reasonable advance notice subject to the rights of
tenants, subtenants and licensees with respect to the Properties.

          (e) Notice of Default.  Borrower shall promptly advise Lender of any
              -----------------                                               
material adverse change in Borrower's financial condition, or of the occurrence
of any Default or Event of Default of which Borrower has knowledge.

          (f) Cooperate in Legal Proceedings.  Borrower shall cooperate fully
              ------------------------------                                 
with Lender with respect to any proceedings before any court, board or other
Governmental Authority which may in any way affect the rights of Lender
hereunder or any rights obtained by Lender under any of the other Loan Documents
and, in connection therewith, permit Lender, at its election and at its cost, to
participate in any such proceedings.

reimbursed for any expenses reasonably incurred in connection therewith
(including reasonable attorneys' fees and disbursements, and the payment by
Borrower of the expense of an appraisal on behalf of Lender in case of a fire or
other casualty affecting any of the Properties or any part thereof) out of such
Insurance Proceeds.

          (i)  Further Assurances; Supplemental Mortgage Affidavits.  Borrower
               ----------------------------------------------------

          (o) Estoppel Statement.  After request by Lender, Borrower shall

          (r) Leasing Matters.  Borrower may enter into new Leases without the
              ---------------                                                 
consent of Lender, provided that each such new Lease shall provide for rental
rates and terms comparable to existing local market rates and terms (taking into
account the type and quality of tenant, the term of the Lease, the tenant
inducements or concessions under the Lease and the size and quality of the
demised space), shall be arm's-length transactions with bona fide, independent
third party tenants and shall be written on the standard form of lease which
shall have been approved by Lender in its reasonable discretion, without any
change thereto that would have a material adverse effect on the value of the
related Individual Property or materially and adversely affect the value of the
Lease as security for the Debt.  Upon request, Borrower shall furnish Lender
with executed copies of all Leases.  In addition, all renewals of Leases and all
proposed leases shall provide for rental rates and terms comparable to existing
local market rates and terms (taking into account the type and quality of
tenant, the term of the Lease, the tenant inducements or concessions under the
Lease and the size and quality of the demised space) and shall be arm's-length
transactions with bona fide, independent third party tenants.  All Leases shall
provide that they are subordinate to the Mortgage with respect to the related
Individual Property and that the tenant agrees to attorn to Lender, unless
Lender agrees otherwise.  Borrower (i) shall observe and perform in all material
respects all the material obligations imposed upon the landlord under the Leases
and shall not do or permit to be done anything to materially and adversely
affect the value of the Leases as security for the Debt; (ii) shall promptly
send copies to Lender of all notices of default which Borrower shall send or
receive thereunder; (iii) shall enforce all of the material terms, covenants and
conditions contained in the Leases upon the part of the lessee thereunder to be
observed or performed, short of termination thereof, which Borrower deems
reasonably prudent to enforce; (iv) shall not collect any of the Rents more than
one (1) month in advance of when due under the applicable Lease; (v) shall not
execute any other assignment of the lessor's interest in the Leases or the Rents
and (vi) shall not, without the prior written consent of Lender, amend, modify,
waive the provisions of, terminate, reduce the rents under or shorten the term
of any Lease.  Notwithstanding the foregoing, Borrower may, without Lender's
consent (y) amend, modify or waive the provisions of any Leases if such action
does not have a material adverse effect upon the value of the related Individual
Property (taking into account the circumstances of the affected Lease) and (z)
terminate, reduce the rents under or shorten the term of any Leases if such
action (taking into account the planned alternative use of the related demised
space and the circumstances of the affected Lease) does not materially and
adversely affect the value of the related Individual Property.  Borrower shall
not, without the prior consent of Landlord (A) alter, modify or change the terms
of any guaranty, letter of credit or other credit support with respect to the
Leases (a "LEASE GUARANTY") or cancel or terminate such Lease Guaranty (other
           --------------                                                    
than such an action required by the terms of such Lease Guaranty or the related
Lease) if such action could materially and adversely affect the value of the
related Individual Property, or (B) consent to any assignment of or subletting
under the Leases not in accordance with their terms if such action could
materially and adversely affect the value of the related Individual Property.

          (s) Alterations.  Borrower shall obtain Lender's prior written
              -----------                                               
consent, which consent shall not be unreasonably withheld or delayed to any
alterations to any Improvements on any Individual Property that may have a
material adverse effect on Borrower's financial condition, the value of such
Individual Property or the Net Operating 

                                      -60-
<PAGE>
 
Income with respect to such Individual Property, other than tenant improvement
work performed pursuant to the terms and provisions of a Lease and not adversely
affecting any structural component of any Improvements, any utility or HVAC
system contained in any Improvements or the exterior of any building
constituting a part of any Improvements or alterations performed in connection
with the restoration of an Individual Property after the occurrence of a
casualty in accordance with the terms and provisions of this Agreement. If the
total unpaid amounts due and payable with respect to alterations to the
Improvements on the Properties (other than such amounts to be paid or reimbursed
by tenants under the Leases) shall at any time exceed five percent (5%) of the
outstanding principal balance of the Loan (the "THRESHOLD AMOUNT"), Borrower
                                                ----------------
shall promptly deliver to Lender as security for the payment of such amounts and
as additional security for Borrower's obligations under the Loan Documents any
of the following: (i) cash, (ii) U.S. Obligations, (iii) other securities having
a rating acceptable to Lender and that the applicable Rating Agencies have
confirmed in writing will not, in and of itself, result in a downgrade,
withdrawal or qualification of the initial, or, if higher, then current ratings
assigned in connection with any Securitization or (iv) a completion bond or
letter of credit issued by a financial institution having a rating by Standard &
Poor's Ratings Group of not less than A-1+ if the term of such bond or letter of
credit is no longer than three (3) months or, if such term is in excess of three
(3) months, issued by a financial institution having a rating that is acceptable
to Lender and that the applicable Rating Agencies have confirmed in writing will
not, in and of itself, result in a downgrade, withdrawal or qualification of the
initial, or, if higher, then current ratings assigned in connection with any
Securitization. Such security shall be in an amount equal to the excess of the
total unpaid amounts with respect to alterations to the Improvements on the
Properties (other than such amounts to be paid or reimbursed by tenants under
the Leases) over the Threshold Amount and may be reduced from time to time by
the cost estimated by Lender to terminate any of the alterations and restore the
related Individual Property to the extent necessary to prevent any material
adverse effect on the value of such Individual Property.

otherwise replace the Manager or enter into any other management agreements with
respect to any of the Properties; provided, however, that Borrower may replace
the Manager under the Management Agreement with an Affiliate of Manager, which

          (e) Debt Cancellation.  Borrower shall not cancel or otherwise forgive
              -----------------

              ----------------------                                         
party to, any transaction with an Affiliate of Borrower or any of the partners
of Borrower except in the ordinary course of business and on terms which are

shall not be unreasonably withheld or delayed.  If under applicable zoning
provisions the use of all or any portion of any of the Properties is or shall
become a nonconforming use, Borrower shall not cause or permit the nonconforming
use to be discontinued or abandoned without the prior written consent of Lender,

Personal Property, including contingent liability from Operation of Building
Laws, Demolition Costs and Increased Cost of Construction Endorsements, in each
case (A) in an amount equal to one hundred percent (100%) of the "Full

utilities and footings) with a waiver of depreciation, but the amount shall in
no event be less than the outstanding principal balance of the Loan; (B)
containing an agreed amount endorsement with respect to the Improvements and
Personal Property waiving all co-insurance provisions; (C) providing for no
deductible in excess of Ten Thousand and No/100 Dollars ($10,000) for all such
insurance coverage; and (D) containing an "Ordinance or Law Coverage" or
"Enforcement" endorsement if any of the Improvements or the use of the
Individual Property shall at any time constitute legal non-conforming structures
or uses.  In addition, Borrower shall obtain (y) flood hazard if any portion of
the Improvements is currently or at any time in the future located in a
federally designated "special flood hazard area", flood hazard insurance in an
amount equal to the lesser of (1) the outstanding principal balance of the Note

Improvements contain elevators, Five Million and No/100 Dollars ($5,000,000);
(B) to continue at not less than the aforesaid limit until required to be

replaced and operations are resumed, whichever first occurs, and notwithstanding
that the policy may expire prior to the end of such period; and (D) in an amount
equal to one hundred percent (100%) of the projected gross income from the
Individual Property for a period of twelve (12) months from the date that the
Individual Property is repaired or replaced and operations are resumed. The
amount of such business income insurance shall be determined 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 twenty-four
(24) month period. All proceeds payable to Lender pursuant to this subsection
shall be held by Lender and shall be applied to the obligations secured by the
Loan Documents 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 by the Loan Documents
on the respective dates of payment provided for in the Note and the other Loan
Documents except to the extent such amounts are actually paid out of the
proceeds of such business income insurance;

               (iv) at all times during which structural construction, repairs
or alterations are being made with respect to the Improvements, and only if the
Individual Property coverage form does not otherwise apply, (A) owner's

the commercial property insurance policy required under subsection (i) above;

               (vii) umbrella liability insurance in an amount not less than Ten
Million and No/100 Dollars ($10,000,000) per occurrence on terms consistent with
the commercial general liability insurance policy required under subsection (ii)
above;

owned vehicles, including rented and leased vehicles containing minimum limits
per occurrence, including umbrella coverage, of Five Million and No/100 Dollars
($5,000,000); and

               (ix) upon sixty (60) days' written notice, such other reasonable
insurance and in such reasonable amounts as Lender from time to time may
reasonably request against such other insurable hazards which at the time are

any such change with the requirements of Section 7.1.1(a).  The Policies shall

paying ability rating of "AA" (or its equivalent) or better by at least two (2)
of the Rating Agencies one of which shall be Standard & Poor's Ratings Group if
Standard & Poor's Ratings Group is one of the Rating Agencies issuing a rating

Lender, evidence that the Policies have been renewed and, no later than five (5)
days prior to the date due, evidence satisfactory to Lender of payment of the
premiums due thereunder (the "INSURANCE PREMIUMS"), shall be delivered by

Borrower to Lender; provided, however, that Borrower's obligation to directly
pay Insurance Premiums shall be suspended for so long as Borrower complies with
the terms and provisions of Section 7.3.
                            ----------- 

          (c) Any blanket insurance Policy shall specifically allocate to the
Individual 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 Section
                                                                -------

Borrower as the insured and Lender as the additional insured, as its interests
may appear, and in the case of property damage, boiler and machinery, flood and
earthquake insurance, shall contain a so-called New York standard non-
contributing mortgagee clause in favor of Lender providing that the loss
thereunder shall be payable to Lender.

          (e) All Policies of insurance provided for in Section 7.1.1(a)(v)
                                                        -------------------
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, other than the failure to pay the
related Insurance Premium, 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 thereby) or canceled without at least thirty (30)
days' written notice to Lender and any other party named therein as an
additional insured; and

                                      -66-

days prior to its expiration; and

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

          (f) 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, 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 reasonable
discretion deems necessary to satisfy the requirements of Section 7.1.1(a), and
                                                          ----------------     
all premiums 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 the Mortgages and shall bear interest
at the Default Rate.

          (g) If the Individual Property shall be damaged or destroyed, in whole
or in part, by fire or other casualty, Borrower shall give prompt notice of such
damage to Lender and shall promptly commence and diligently prosecute the
completion of the repair and restoration of the Individual Property as nearly as
possible to the condition the Individual Property was in immediately prior to
such fire or other casualty, with such alterations as may be reasonably approved
by Lender (a "RESTORATION") and otherwise in accordance with Section 7.1.3.
              -----------                                    -------------  
Borrower shall pay all costs of such Restoration whether or not such costs are
covered by insurance.  Lender may, but shall not be obligated to make proof of
loss if not made promptly by Borrower;

          (h) In the event of foreclosure of the Mortgage with respect to the
Individual Property, or other transfer of title to the Individual Property in
extinguishment in whole or in part of the Debt all right, title and interest of
Borrower in and to the Policies  that are not blanket Policies then in force
concerning the Individual Property and all proceeds payable thereunder shall
thereupon vest in the purchaser at such foreclosure or Lender or other
transferee in the event of such other transfer of title.

          SECTION 7.1.2  CONDEMNATION.  Borrower shall promptly give Lender
                         ------------                                      
notice of the actual or threatened commencement of any condemnation or eminent
domain proceeding affecting any of the Properties and shall deliver to Lender
copies of any and all papers served in connection with such proceedings.  Lender
may participate in any such proceedings, and Borrower shall from time to time
deliver to Lender all instruments requested by it to permit such participation.
Borrower shall, at its expense, diligently prosecute any such proceedings, and
shall consult with Lender, its attorneys and experts, and cooperate with them in
the carrying on or defense of any such proceedings. 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
Agreement and the Debt shall not be reduced until any award or payment therefor
(an "AWARD") shall have been actually received and applied by Lender, after the

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. If the Property or any portion thereof is taken
by a condemning authority, Borrower shall promptly commence and diligently
prosecute the Restoration of the Property and otherwise comply with the
provisions of Section 7.1.3. If the Property is sold, through foreclosure
              -------------                                               
or otherwise, prior to the receipt by Lender of the Award, 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 a portion thereof sufficient to
pay the Debt.

No/100 Dollars ($500,000) and the costs of completing the Restoration shall be
less than Five Hundred Thousand and No/100 Dollars ($500,000), the Net Proceeds
will be disbursed by Lender to Borrower upon receipt, provided that all of the

Thousand and No/100 Dollars ($500,000) or the costs of completing the
Restoration is equal to or greater than Five Hundred Thousand and No/100 Dollars

               does not result in the loss of reasonably adequate access to the
               Individual Property or the related Improvements.

               (ii) The Net Proceeds shall be held by Lender in an interest-
          bearing account and, until disbursed in accordance with the provisions

          shall be disbursed by Lender to, or as directed by, Borrower from time
          to time during the course of the Restoration, upon receipt of evidence
          reasonably satisfactory to Lender that (A) all materials installed and
          work and labor performed (except to the extent that they are to be
          paid for out of the requested disbursement) in connection with the
          Restoration have been paid for in full, and (B) there exist no notices
          of pendency, stop orders, mechanic's or materialman's liens or notices
          of intention to file same, or any other liens or encumbrances of any
          nature whatsoever on the Individual Property arising out of the
          Restoration which have not either been fully bonded to the reasonable
          satisfaction of Lender and discharged of record or in the alternative
          fully insured to the satisfaction of Lender by the title company
          issuing the Title Insurance Policy.

               (iii)  All plans and specifications required in connection with
          the Restoration shall be subject to prior review and acceptance in all

          contractors, subcontractors and materialmen engaged in the
          Restoration, as well as the contracts under which they have been
          engaged, shall be subject to prior review and acceptance by Lender and
          the Casualty Consultant and such acceptance shall not be unreasonably
          withheld.  All reasonable costs and expenses incurred by Lender in
          connection with making the Net Proceeds available for the Restoration
          including, without limitation, reasonable counsel fees and
          disbursements and the Casualty Consultant's fees, shall be paid by
          Borrower.

               (iv) In no event shall Lender be obligated to make disbursements
          of the Net Proceeds in excess of an amount equal to the costs actually
          incurred from time to time for work in place as part of the
          Restoration, as certified by the Casualty Consultant, minus the
                                                                -----

          amount equal to ten percent (10%) of the costs actually incurred for
          work in place as part of the Restoration, as certified by the Casualty
          Consultant, until the Restoration has been completed.  The Casualty
          Retainage shall in no event, and notwithstanding anything to the
          contrary set forth above in this Section 7.1.3(b), be less than the
                                           ----------------                  
          amount actually held back by Borrower from contractors, subcontractors
          and materialmen engaged in the Restoration.  The Casualty Retainage
          shall not be released until the Casualty Consultant certifies to
          Lender that the Restoration has been completed in accordance with the
          provisions of this Section 7.1.3(b) and that all approvals necessary
                             ----------------                                 
          for the re-occupancy and use of the Individual Property have been
          obtained from all appropriate governmental and quasi-governmental
          authorities, and Lender receives evidence satisfactory to Lender that
          the costs of the Restoration have been paid in full or will be paid in
          full out of the Casualty Retainage; provided, however, that Lender
          will release the portion of the Casualty Retainage being held with
          respect to any contractor, subcontractor or materialman engaged in the
          Restoration as of the date upon which the Casualty Consultant
          certifies to Lender that the contractor, subcontractor or materialman
          has satisfactorily completed all work and has supplied all materials
          in accordance with the provisions of the contractor's, subcontractor's
          or materialman's contract, the contractor, subcontractor or
          materialman delivers the lien waivers and evidence of payment in full
          of all sums due to the contractor, subcontractor or materialman as may
          be reasonably requested by Lender or by the title company issuing the
          Title Insurance Policy, and Lender receives an endorsement to the
          Title Insurance Policy insuring the continued priority of the lien of
          the related Mortgage and evidence of payment of any premium payable
          for such endorsement.  If required by Lender, the release of any such
          portion of the Casualty Retainage shall be approved by the surety
          company, if any, which has issued a payment or performance bond with
          respect to the contractor, subcontractor or materialman.

               (v) Lender shall not be obligated to make disbursements of the
          Net Proceeds more frequently than once every calendar month.

               (vi) If at any time the Net Proceeds or the undisbursed balance
          thereof shall not, in the reasonable opinion of Lender in consultation
          with the Casualty Consultant, be sufficient to pay in full the balance
          of the costs which are estimated by the Casualty Consultant to be
          incurred in connection with the completion of the Restoration,
          Borrower shall deposit the deficiency (the "NET PROCEEDS DEFICIENCY")

          with Lender before any further disbursement of the Net Proceeds shall
          be made.  The Net Proceeds Deficiency deposited with Lender shall be
          held by Lender and shall be disbursed for costs actually incurred in
          connection with the Restoration on the same conditions applicable to
          the 

                                      -71-

          disbursement of the Net Proceeds, and until so disbursed pursuant
          to this Section 7.1.3(b) shall constitute additional security for the

          Debt and other obligations under the Loan Documents.

               (vii)  The excess, if any, of the Net Proceeds and the remaining
          balance, if any, of the Net Proceeds Deficiency deposited with Lender
          after the Casualty Consultant certifies to Lender that the Restoration
          has been completed in accordance with the provisions of this Section
                                                                       -------
          7.1.3(b), and the receipt by Lender of evidence satisfactory to Lender
          --------                                                              
          that all costs incurred in connection with the Restoration have been
          paid in full, shall be remitted by Lender to Borrower, provided no
          Event of Default shall have occurred and shall be continuing under the
          Note, this Security Instrument or any of the Other Security Documents.

          (c) All Net Proceeds not required (i) to be made available for the
Restoration or (ii) to be returned to Borrower as excess Net Proceeds pursuant
to Section 7.1.3(b)(vii) may be retained and applied by Lender toward the
   ---------------------                                                 
payment of the Debt, without the payment of any premium or penalty in connection
with the prepayment of any portion of the principal balance of the Loan, or, at
the discretion of Lender, the same may be paid, either in whole or in part, to
Borrower for such purposes as Lender shall designate, in its discretion.  All
Net Proceeds retained and applied by Lender to the Debt shall be applied (A)
first, to the payment of all interest then due and owing under the Loan, (B)
second, to the payment of all other amounts then due and owing under the Loan
and the Loan Documents and (C) third, to the outstanding principal amount of the
Loan and the reduction of the Pro rata Release Amount with respect to the
Individual Property affected by the related casualty or condemnation; provided,
however, that the application of Net Proceeds set forth in clause (C) shall not
reduce the outstanding principal balance of the Loan for purposes of calculating
the Pro rata Release Amount of any Individual Property other than the Individual
Property affected by the related casualty or condemnation.  If the Net Proceeds
applied as set forth in clause (C) above exceed the Pro rata Release Amount of
the Individual Property affected by the related casualty or condemnation, the
Pro rata Release Amount of each Individual Property other than the affected
Individual Property shall be reduced by the product of (1) such excess Net
Proceeds multiplied by (2) the quotient of the Pro rata Release Amount of such
other Individual Property divided by the total Pro rata Release Amounts of all
of the Properties other than the affected Individual Property.

estimates will be payable during the next ensuing twelve (12) months in order to
accumulate with Lender sufficient funds to pay all such Taxes at least ten (10)
days prior to their respective due dates, and (ii) one-twelfth of the Insurance
Premiums that Lender estimates will be payable for the renewal of the coverage
afforded by the Policies with respect to all of the Properties upon the

all such Insurance Premiums at least thirty (30) days prior to the expiration of
the Policies (said amounts in (i) and (ii) above hereinafter called the "TAX AND
                                                                         -------
INSURANCE ESCROW FUND").  The Tax and Insurance Escrow Fund and the payments of
---------------------                                                          
interest or principal or both, payable pursuant to the Note, shall be added
together and shall be paid as an aggregate sum by Borrower to Lender.  Lender
will maintain the Tax and Escrow Fund in a segregated account and shall be
invested and reinvested by Lender, at Borrower's direction, in one or more
Eligible Investments, subject to the following restrictions:  (A) such Eligible
Investments and the proceeds thereof shall be deemed a part of the Tax and
Insurance Escrow Fund; (B) each such Eligible Investment shall be made in the
name of Lender (in its capacity as such) or in the name of a nominee of Lender
under its complete and exclusive dominion and control or, if applicable law
provides for perfection of pledges of an instrument not evidenced by a
certificate or other instrument through registration of such pledge on books
maintained by or on behalf of the issuer of such investment, such pledge may be
so registered; (C) Lender shall have the sole control over such investment, the
income thereon and the proceeds thereof; (D) other than investments described in
clause (B) above, any certificate or other instrument evidencing such investment
shall be delivered directly to Lender or its agent; and (E) the proceeds of each
investment shall be remitted by the purchaser thereof directly to Lender.
Lender will apply the Tax and Insurance Escrow Fund to payments of Taxes and
Insurance Premiums required to be made by Borrower pursuant to Section 5.1
                                                               -----------
hereof and under the Mortgages.  In making any payment relating to the Tax and
Insurance Escrow Fund, Lender may do so according to any bill, statement or
estimate procured from the appropriate public office (with respect to Taxes) or
insurer or agent (with respect to Insurance Premiums), without inquiry into the
accuracy of such bill, statement or estimate or into the validity of any tax,
assessment, sale, forfeiture, tax lien or title or claim thereof, unless
Borrower has notified Lender of Borrower's intention to contest any such Tax in
accordance with Section 5.1(b) hereof and promptly proceeds with such contest.
                --------------                                                 
If the amount of the Tax and Insurance Escrow Fund shall exceed the amounts due
for Taxes and Insurance Premiums pursuant to Section 5.1 hereof, Lender shall,
                                             -----------                      
in its sole discretion, return any excess to Borrower or credit such excess
against future payments to be made to the Tax and Insurance Escrow Fund.  Any
amount remaining in the Tax and Insurance Escrow Fund after the Debt has been
paid in full shall be returned to Borrower.  In allocating such excess, Lender
may deal with the Person shown on the records of Lender to be the owner of the
Properties.  If at any time Lender reasonably determines that the Tax and
Insurance Escrow Fund is not or will not be sufficient to pay the items set
forth in clauses (i) and (ii) above, Lender shall notify Borrower of such
determination and Borrower shall increase its monthly payments to Lender by the
amount that Lender estimates is sufficient to make up the deficiency at least
ten (10) days prior to delinquency of the Taxes and/or thirty (30) days prior to
expiration of the Policies, as the case may be.

          7.3.2  GRANT OF SECURITY INTEREST.  Borrower hereby pledges, assigns
                 --------------------------                                   
and grants a security interest to Lender, as security for payment of all sums
due under the Loan and the performance of all other terms, conditions and
provisions of the Loan Documents and this Agreement on Borrower's part to be
paid and performed, of all Borrower's right, title and interest in and to the
Tax and Insurance Escrow Fund.  Borrower shall not, without obtaining the prior
written consent of Lender, further pledge, assign or grant any security interest
in the

Tax and Insurance Escrow Fund or permit any lien or encumbrance to attach

                 --------------------------------------------                 
or applied as above provided, any amounts in the Tax and Insurance Escrow Fund
shall constitute additional security for the Debt.  Upon the occurrence of an
Event of Default, Lender may apply any sums then present in the Tax and
Insurance Escrow Fund to the payment of the following items in any order in its
sole discretion: (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; or (v) all other sums payable pursuant to
this Agreement and the other Loan Documents.

                       --------------------- 

          SECTION 7.5  GROUND LEASE ESCROW FUND.
                       ------------------------ 

          Borrower shall pay to Lender, together with the scheduled payment of
principal and interest under the Loan each month, an amount that is estimated by
Lender to be due and payable by Borrower under the Ground Lease for all rent and
any and all other charges which may be due by Borrower under the Ground Lease in
order to accumulate with Lender sufficient funds to pay all sums payable under
the Ground Lease at least ten (10) Business Days prior to the dates due (said
amounts, hereinafter called the "GROUND LEASE ESCROW FUND").  The Ground Lease
                                 ------------------------                     
Escrow Fund is for the purpose of paying all sums due under the Ground Lease.
Upon Borrower's failure to pay any rent or other charges due under the Ground
Lease after the receipt of any notice and the expiration of any cure period
available to Borrower pursuant to the Ground Lease, Lender may, in its
discretion, apply any amounts held in the Ground Lease Escrow Fund to the
payment of such rent or other charges; provided however, that the provisions of
this Section 7.5 shall not be deemed to create any obligation on the part of
     -----------                                                            
Lender to pay any such rent or other charges from amounts on deposit in the
Ground Lease Escrow Fund.  Borrower hereby pledges, assigns and grants a
security interest to Lender, as security for payment of all sums due under the
Loan and the performance of all other terms, conditions and provisions to be
paid and performed, of all Borrower's right, title and interest in and to the
Ground Lease Escrow Fund.  Borrower shall not, without obtaining the prior
written consent of Lender, further pledge, assign or grant any security interest
in the Ground Lease Escrow Fund or permit any lien or encumbrance to attach
thereto, or any levy to be made thereon, or any UCC-1 Financing Statements,
except those naming Lender as the secured party, to be filed with respect
thereto.  Upon the occurrence of an Event of Default, Lender may apply any sums
then present in the Ground Lease Escrow Fund to the payment of the Debt in any
order in its sole discretion.  Until expended or applied as above provided, the
Ground Lease Escrow Fund shall constitute additional security for the Debt.
Notwithstanding the foregoing, the Borrower shall not be required to make
monthly deposits to the Ground Lease Escrow Fund so long as on the Closing Date
and for the remainder of the Term, the Borrower has deposited and maintains in
the Ground Lease Escrow Fund sufficient amounts for the payment of three (3)
months of rent and any and all other charges under the Ground Lease.  Such
initial deposit may be increased by Lender in the amount Lender deems is

                                      -74-
<PAGE>
 
necessary in its reasonable discretion based on any increases in the rent due
under the Ground Lease.

provided, however, that in the case of any such representation or warranty that
is susceptible of cure, if such representation or warranty shall remain uncured

contained in Section 6.1 that is not susceptible of cure or any covenant

contained in Section 4.1(ee) hereof;
             ---------------        

              (x) with respect to any term, covenant or provision set forth
herein which specifically contains a notice requirement or grace period, if
Borrower shall be in default under such term, covenant or condition after the
giving of such notice or the expiration of such grace period;

              (xi) if any of the assumptions contained in the Insolvency Opinion
delivered to Lender in connection with the Loan, or in any other "non-
consolidation" opinion delivered subsequent to the closing of the Loan, is or
shall become untrue in any material respect;

              (xii) if Borrower shall fail to comply with the terms and
provisions of (a) that certain letter agreement dated the date hereof between
Borrower and Lender with respect to the Initial Advance post closing-obligations
or (b) the certain letter agreement between Borrower and Lender regarding post-
closing obligations with respect to the Subsequent Advance;

              (xiii) if a default on the part of Borrower shall have occurred
under the Ground Lease and continued beyond any applicable notice and grace
period;

              (xiv) if Borrower shall continue to be in Default under any of the
other terms, covenants or conditions of this Agreement not specified in
subsections (i) to (xiii) above, for ten (10) days after notice to Borrower from
Lender, in the case of any Default which can be cured by the payment of a sum of
money, or for thirty (30) days after written notice from Lender in the case of
any other Default; provided, however, that if such non-monetary Default is
susceptible of cure but cannot reasonably be cured within such 30-day period and
provided further that Borrower shall have commenced to cure such Default within
such 30-day period and thereafter diligently and expeditiously proceeds to cure
the same, such 30-day period shall be extended for such time as is reasonably
necessary for Borrower in the exercise of due diligence to cure such Default,
such additional period not to exceed one hundred eighty days (180); or

              (xv) if there shall be default under any of the other Loan
Documents beyond any applicable cure periods contained in such documents,
whether as to Borrower or any of the Properties, or if any other such event
shall occur or condition shall exist, if the 

                                      -76-
<PAGE>
 
effect of such event or condition is to accelerate the maturity of any portion
of the Debt or to permit Lender to accelerate the maturity of all or any portion
of the Debt.

          (b) Upon the occurrence of an Event of Default (other than an Event of
Default described in clauses (vi), (vii) or (viii) above) and at any time
thereafter Lender may, in addition to any other rights or remedies available to
it pursuant to this Agreement and the other Loan Documents or at law or in
equity, take such action, without notice or demand, that Lender deems advisable
to protect and enforce its rights against Borrower and in and to all or any of
the Properties, including, without limitation, declaring the Debt to be
immediately due and payable, and Lender may enforce or avail itself of any or
all rights or remedies provided in the Loan Documents against Borrower and any
or all of the Properties, including, without limitation, all rights or remedies
available at law or in equity; and upon any Event of Default described in
clauses (vi), (vii) or (viii) above, the Debt and all other obligations of
Borrower hereunder and under the other Loan Documents shall immediately and
automatically become due and payable, without notice or demand, and Borrower
hereby expressly waives any such notice or demand, anything contained herein or
in any other Loan Document to the contrary notwithstanding.

          (c) The parties hereto acknowledge that a Default or an Event of
Default arising solely from a Non-Curable Property Default shall no longer exist
upon the release of the Individual Property affected by such Non-Curable
Property Default from the Lien of the Mortgage thereon (and related Loan
Documents) pursuant to Section 2.4.2 or Section 2.7.
                       -------------    ----------- 

          SECTION 8.2  REMEDIES.
                       -------- 

          (a) Upon the occurrence and during the continuance of an Event of
Default, all or any one or more of the rights, powers, privileges and other
remedies available to Lender against Borrower under this Agreement or any of the
other Loan Documents executed and delivered by, or applicable to, Borrower or at
law or in equity may be exercised by Lender at any time and from time to time,
whether or not all or any of the Debt shall be declared due and payable, and
whether or not Lender shall have commenced any foreclosure proceeding or other
action for the enforcement of its rights and remedies under any of the Loan
Documents with respect to all or any of the Properties.  Any such actions taken
by Lender shall be cumulative and concurrent and may be pursued independently,
singly, successively, together or otherwise, at such time and in such order as
Lender may determine in its sole discretion, to the fullest extent permitted by
law, without impairing or otherwise affecting the other rights and remedies of
Lender permitted by law, equity or contract or as set forth herein or in the
other Loan Documents.  Without limiting the generality of the foregoing,
Borrower agrees that if an Event of Default is continuing (i) Lender is not
subject to any "one action" or "election of remedies" law or rule, (ii) all
liens and other rights, remedies or privileges provided to Lender shall remain
in full force and effect until Lender has exhausted all of its remedies against
the Properties and each Mortgage has been foreclosed, sold and/or otherwise
realized upon in satisfaction of the Debt or the Debt has been paid in full, and
(iii) to the extent permitted by applicable law, Borrower hereby waives any and
all rights it may have by statute to assert that Lender is not entitled to any
additional recovery from the Properties because 

                                      -77-
<PAGE>
 
Lender has not claimed a deficiency within the time prescribed by such statute
or otherwise failed to meet the procedural requirement for claiming a deficiency
judgment.

          (b) With respect to Borrower and the Properties, nothing contained
herein or in any other Loan Document shall be construed as requiring Lender to
resort to any Individual Property for the satisfaction of any of the Debt in
preference or priority to any other Individual Property, and Lender may seek
satisfaction out of all of the Properties or any part thereof, in its absolute
discretion in respect of the Debt.  In addition, Lender shall have the right
from time to time to partially foreclose the Mortgages in any manner and for any
amounts secured by the Mortgages then due and payable as determined by Lender in
its sole discretion including, without limitation, the following circumstances:
(i) in the event Borrower defaults beyond any applicable grace period in the
payment of one or more scheduled payments of principal and interest, Lender may
foreclose one or more of the Mortgages to recover such delinquent payments, or
(ii) in the event Lender elects to accelerate less than the entire outstanding
principal balance of the Loan, Lender may foreclose one or more of the Mortgages
to recover so much of the principal balance of the Loan as Lender may accelerate
and such other sums secured by one or more of the Mortgages as Lender may elect.
Notwithstanding one or more partial foreclosures, the Properties shall remain
subject to the Mortgages to secure payment of sums secured by the Mortgages and
not previously recovered.

          (c) Lender shall have the right from time to time to sever the Note
and the other Loan Documents into one or more separate notes, mortgages and
other security documents (the "SEVERED LOAN DOCUMENTS") in such denominations as
                               ----------------------                           
Lender shall determine in its sole discretion for purposes of evidencing and
enforcing its rights and remedies provided hereunder.  Borrower shall execute
and deliver to Lender from time to time, promptly after the request of Lender, a
severance agreement and such other documents as Lender shall request in order to
effect the severance described in the preceding sentence, all in form and
substance reasonably satisfactory to Lender.  Borrower shall not be obligated to
pay any costs or expenses incurred in connection with the preparation,
execution, recording or filing of the Severed Loan Documents and the Severed
Loan Documents shall not contain any representations, warranties or covenants
not contained in the Loan Documents and any such representations and warranties
contained in the Severed Loan Documents will be given by Borrower only as of the
Closing Date.

          SECTION 8.3  REMEDIES CUMULATIVE.
                       ------------------- 

          The rights, powers and remedies of Lender under this Agreement shall
be cumulative and not exclusive of any other right, power or remedy which Lender
may have against Borrower pursuant to this Agreement or the other Loan
Documents, or existing at law or in equity or otherwise.  Lender's rights,
powers and remedies may be pursued singly, concurrently or otherwise, at such
time and in such order as Lender may determine in Lender's sole discretion.  No
delay or omission to exercise any remedy, right or power accruing upon an Event
of Default shall impair any such remedy, right or power or shall be construed as
a waiver thereof, but any such remedy, right or power may be exercised from time
to time and as often as may be deemed expedient.  A waiver of one Default or
Event of Default with respect to Borrower shall not be construed to be a waiver
of any subsequent 

                                      -78-
<PAGE>
 
Default or Event of Default by Borrower or to impair any remedy, right or power
consequent thereon.

multi-class securities (the "SECURITIES") secured by or evidencing ownership
                             ----------                                     
interests in the Note and the Mortgages, including, without limitation, to:

          (a)  (i)  provide such financial and other information with respect to
               the Properties, the Borrower and the Manager, (ii) provide
               budgets relating to the Properties and (iii) to permit to be

               reasonably requested by the holder of the Note or the Rating
               Agencies or as may be reasonably necessary or appropriate in
               connection with the Securitization (the "PROVIDED INFORMATION"),
                                                        --------------------   
               together, if customary, with appropriate verification of and/or
               consents to the use of the Provided Information through letters
               of auditors or opinions of counsel of independent attorneys
               reasonably acceptable to the Lender and acceptable to the Rating
               Agencies; provided, however, that Phase II reports and other
               invasive testing may not be performed at any of the Properties
               until Borrower has received reasonably appropriate
               indemnifications and evidence of insurance from any Person
               preparing such report or performing such testing;

          (b)  cause counsel to render opinions as to non-consolidation,
               fraudulent conveyance, and true sale or any other opinion
               customary in securitization transactions with respect to the
               Properties and Borrower and its affiliates, which counsel and
               opinions shall be reasonably satisfactory to the holder of the
               Note and the Rating Agencies;

          (c)  make such representations and warranties as of the closing date
               of the Securitization with respect to the Properties, Borrower,
               and the Loan Documents as are customarily provided in
               securitization transactions and 

                                      -79-
<PAGE>
 
               as may be reasonably requested by the holder of the Note or the
               Rating Agencies and consistent with the facts covered by such
               representations and warranties as they exist on the date thereof
               to the extent such representations and warranties are true as of
               the closing date of the Securitization, including the
               representations and warranties made in the Loan Documents to the
               extent such representations and warranties are true as of the
               closing date of the Securitization; and

          (d)  execute such amendments to the Loan Documents and organizational
               documents and enter into a lockbox or similar arrangement with
               respect to the Rents as may be reasonably requested by the holder
               of the Note or as may be requested by the Rating Agencies or as
               may be otherwise necessary to effect the Securitization;
               provided, however, that the Borrower shall not be required to
               modify or amend any Loan Document if such modification or
               amendment would (i) change the interest rate, the stated maturity
               or the amortization of principal set forth in the Note, or (ii)
               modify or amend any other material economic term of the Loan or
               materially increase Borrower's obligations or liabilities under
               the Loan Documents.  Notwithstanding the foregoing, Lender may
               elect to change the Maturity to the Anticipated Repayment Date in
               connection with the Securitization and Borrower shall execute
               such amendments to the Loan Documents as Lender shall determine
               are necessary to reflect such change.

All third party costs and expenses incurred by Lender in connection with the
Securitization or other sale or transfer of the Loan and all reasonable third
party costs and expenses incurred by Borrower in connection with the
Securitization or other sale or transfer of the Loan shall be paid by Lender.

its directors, each of its officers who have signed the Registration Statement
and each person or entity who controls the Affiliate within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act
(collectively, the "LEHMAN GROUP"), and Lehman, each of its directors and each
                    ------------
person who controls Lehman within the meaning of Section 15 of the Securities
Act and Section 20 of the Exchange Act (collectively, the "UNDERWRITER GROUP")
                                                           -----------------
for any losses, claims, damages or liabilities (the "LIABILITIES") to which
                                                     -----------
Lender, the Lehman Group or the Underwriter Group may become subject insofar as
the Liabilities arise out of any untrue statement or alleged untrue statement of
any material fact contained in such sections (other than any such statement made
in reliance upon the reports of third parties that do not, to Borrower's
knowledge, contain any untrue statement of a material fact or omit to state a
material fact necessary in order to make the statements made, in light of the
circumstances under which they were made, not misleading) or arise out of the
omission or alleged omission to state therein a material fact known to Borrower
and required to be stated in such sections or necessary in order to make the
statements in such sections or in light of the circumstances under which they
were made, not misleading and (C) agreeing to reimburse Lender, the Lehman Group
and the Underwriter Group for any legal or other expenses reasonably incurred by
Lender and Lehman in connection with investigating or defending the Liabilities;
provided, however, that Borrower will be liable in any such case under clauses
(B) or (C) above only to the extent that any such loss claim, damage, liability
or expense arises out of any such untrue statement or omission made therein in
reliance upon and in conformity with written information furnished to Lender by
or on behalf of Borrower expressly for use in the Disclosure Document; and
provided further, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Borrower by
Lender, any member of the Lehman Group or any member of the Underwriter Group
expressly for use in the Disclosure Document. The foregoing indemnity with
respect to any untrue statement contained in or omission from a preliminary
private placement memorandum or preliminary prospectus shall not inure to the
benefit of any member of the Underwriting Group (or any person controlling such
member of the Underwriting Group) from whom the Person asserting any such loss,
liability, claim, damage or expense purchased any of the Securities which are
the subject thereof if the Borrower shall sustain the burden of proving that any
such loss, liability, claim, damage or expense resulted from the fact that such
Person was not sent or given a copy of the

                                      -81-
<PAGE>
 
final private placement memorandum or final prospectus at or prior to the
written confirmation of the sale of such Security to such Person and the loss,
liability, claim, damage or expense resulted from an untrue statement contained
in or omission from such preliminary private placement memorandum or preliminary
prospectus that was corrected in the final private placement memorandum or final
prospectus.

          (c) In connection with filings under the Exchange Act, Borrower agrees
to indemnify (i) Lender, the Lehman Group and the Underwriter Group for
Liabilities to which Lender, the Lehman Group or the Underwriter Group may
become subject insofar as the Liabilities arise out of or are based upon the
omission or alleged omission to state in the Provided Information or Required
Records a material fact required to be stated in the Provided Information or
Required Records in order to make the statements in the Provided Information or
Required Records, in light of the circumstances under which they were made not
misleading and (ii) reimburse Lender, the Lehman Group or the Underwriter Group
for any legal or other expenses reasonably incurred by Lender, the Lehman Group
or the Underwriter Group in connection with defending or investigating the
Liabilities.

          (d) Lehman agrees to indemnify and hold harmless Borrower, each of its
directors and each person who controls Borrower within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act (the "BORROWER GROUP")
                         ----------                           --------------  
against any and all losses, claims, damages or liabilities, joint or several, to
which such group may become subject, under the Securities Act or otherwise, and
will reimburse such group for any legal or other expenses reasonably incurred by
such group in connection with investigating or defending any such loss, claim,
damage, liability or action, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in a
Disclosure Document or arise out of or are based upon the omission or the
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, but only to the extent that such untrue
statement or alleged untrue statement or omission or alleged omission relates to
information that does not accurately reflect Provided Information.

          (e) Promptly after receipt by an indemnified party under this Section
                                                                        -------
9.2 of notice of the commencement of any action, such indemnified party will, if
---                                                                             
a claim in respect thereof is to be made against the indemnifying party under
this Section 9.2, notify the indemnifying party in writing of the commencement
     -----------                                                              
thereof, but the omission to so notify the indemnifying party will not relieve
the indemnifying party from any liability which the indemnifying party may have
to any indemnified party hereunder except to the extent that failure to notify
causes prejudice to the indemnifying party.  In the event that any action is
brought against any indemnified party, and it notifies the indemnifying party of
the commencement thereof, the indemnifying party will be entitled, jointly with
any other indemnifying party, to participate therein and, to the extent that it
(or they) may elect by written notice delivered to the indemnified party
promptly after receiving the aforesaid notice from such indemnified party, to
assume the defense thereof with counsel satisfactory to such indemnified party,
provided that no compromise or settlement shall be entered without the consent
of such indemnified party, which consent shall not be unreasonably withheld.
After

notice from the indemnifying party to such indemnified party under the
immediately preceding sentence of this Section 9.2 and except as otherwise
                                       -----------                        
explicitly provided herein, the indemnifying party shall not be responsible for
any legal or other expenses subsequently incurred by such indemnified party in
connection with the defense thereof; provided, however, if the defendants in any
such action include both the indemnified party and the indemnifying party and
the indemnified party shall have reasonably concluded that there are any legal
defenses available to it and/or other indemnified parties that are different
from or additional to those available to the indemnifying party, the indemnified
party or parties shall have the right to select separate counsel to assert such
legal defenses and to otherwise participate in the defense of such action on
behalf of such indemnified party or parties.  The indemnifying party shall not
be liable for the expenses of more than one separate counsel unless an
indemnified party shall have reasonably concluded that there may be legal
defenses available to it that are different from or additional to those
available to another indemnified party.  In no event shall an indemnifying party
be liable to an indemnified party under this Section 9.2 for any losses, claims,
                                             -----------                        
damages or liabilities to which such indemnified party may become subject to the
extent the same arise by reason of the gross negligence, illegal acts, fraud or
willful misconduct of such indemnified party.

          (f) In order to provide for just and equitable contribution in
circumstances in which the indemnity agreement provided for in Section 9.2(b),
                                                               ---------------
(c) or (d) is for any reason held to be unenforceable by an indemnified party in
---   ----                                                                      
respect of any losses, claims, damages or liabilities (or action in respect
thereof) referred to therein which would otherwise be indemnifiable under
                                                                         
Section 9.2(b), (c) or (d), the indemnifying party shall contribute to the
-------------------   ----                                                
amount paid or payable by the indemnified party as a result of such losses,
claims, damages or liabilities (or action in respect thereof); provided,
however, that no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation; and provided further, that Borrower will be liable under this
                                                                                
Section 9.2(f) only to the extent that any such loss, claim, damage or liability
--------------                                                                  
(or action in respect thereof) arises out of any untrue statement or omission
made therein in reliance upon and in conformity with written information
furnished to Lender by Borrower expressly for use in the Disclosure Document or
any failure to state any material fact known to Borrower and required to be
stated in such written information in order to make such written information in
light of the circumstances under which they were made not misleading.  In
determining the amount of contribution to which the respective parties are
entitled, the following factors shall be considered: (i) Lehman's and Borrower's
relative knowledge and access to information concerning the matter with respect
to which claim was asserted; (ii) the opportunity to correct and prevent any
statement or omission; and (iii) any other equitable considerations appropriate
in the circumstances.  Lehman and Borrower hereby agree that it would not be
equitable if the amount of such contribution were determined by pro rata or per
capita allocation.

          (g) The liabilities and obligations of both Borrower and Lender under
this Section 9.2 shall survive the termination of this Agreement and the
     -----------                                                        
satisfaction and discharge of the Debt.

          The Borrower will cooperate with Lender to retain the Rating Agencies
to provide rating surveillance services on any certificates issued in a
Securitization.  Such rating surveillance will be at the expense of Lender.

shall not enforce the liability and obligation of Borrower to perform and
observe the obligations contained in the Note, this Agreement or any other Loan
Document 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 Mortgages or any other Loan Document, and the
interest in the Properties, the Rents and any other collateral given to Lender
created by the 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 Properties, in the Rents and in any other collateral
given to Lender.  Lender, by accepting the Note and this Agreement, agrees that
it shall not, except as otherwise provided in Section 7.10 of the Mortgages, sue
for, seek or demand any deficiency judgment against Borrower, its partners or
any officer, employee or director of any partner of Borrower in any action or
proceeding, under or by reason of or under or in connection with the Note, this
Agreement or the other Loan Documents.

executed in connection herewith; (f) impair the right of Lender to obtain a
deficiency judgment or judgment on the Note against Borrower if necessary to

                         ----------------

Loan Documents specifically and expressly provide for the giving of notice by
Lender to Borrower and except with respect to matters for which Borrower is not,

          SECTION 10.11  REMEDIES OF BORROWER.
                         --------------------

Borrower agrees that neither Lender nor its agents shall be liable for any
monetary damages, and Borrower's sole remedies shall be limited to commencing an
action seeking injunctive relief or declaratory judgment.  The parties hereto

          (a)  Borrower covenants and agrees to pay, or if Borrower fails to pay
to reimburse, Lender upon receipt of written notice from Lender for all
reasonable costs and expenses (including reasonable attorneys' fees and
disbursements) incurred by Lender in connection with (i) Borrower's ongoing
performance of and compliance with Borrower's agreements and covenants contained
in this Agreement and the other Loan Documents on its part to be performed or
complied with after the Closing Date, including, without limitation, confirming
compliance with environmental and insurance requirements, other than any such
costs and expenses incurred in connection with the Securitization or other sale
or transfer of the Loan; (ii) Lender's ongoing performance and compliance with
all agreements and conditions contained in this Agreement and the other Loan
Documents on its part to be performed or complied with after the Closing Date,

any payments due from Borrower under this Agreement, the other Loan Documents or
with respect to the Properties or in connection with any refinancing or
restructuring of the credit arrangements provided under this Agreement in the
nature of a "work-out" or of any insolvency or bankruptcy proceedings; provided,
however, that Borrower shall not be liable for the payment of any such costs and
expenses to the extent the same arise by reason of the gross negligence, illegal
acts, fraud or willful misconduct of Lender.  Any cost and expenses due and
payable to Lender in accordance with this Agreement or the other Loan Documents
may be paid from any amounts in the Deposit Account.

          (b) Borrower shall indemnify, defend and hold harmless Lender from and
against any and all other liabilities, obligations, losses, damages, penalties,

misrepresentation by Borrower contained in, this Agreement or the other Loan
Documents, or (ii) the use or intended use of the proceeds of the Loan
(collectively, the "INDEMNIFIED LIABILITIES"); provided, however, that Borrower
                    -----------------------

willful misconduct of Lender.

          SECTION 10.13  EXHIBITS AND SCHEDULES INCORPORATED.
                         ----------------------------------- 

          The Exhibits and Schedules annexed hereto are hereby incorporated
herein as a part of this Agreement with the same effect as if set forth in the
body hereof.

          SECTION 10.14  NO JOINT VENTURE OR PARTNERSHIP;
                         NO THIRD PARTY BENEFICIARIES.
                         -------------------------------

          (a) Borrower and Lender intend that the relationships created
hereunder and under the other Loan Documents be solely that of borrower and
lender.  Nothing herein or therein is intended to create a joint venture,
partnership, tenancy-in-common, or joint tenancy relationship between Borrower
and Lender nor to grant Lender any interest in the Properties other than that of
mortgagee or lender.

          (b) This Agreement and the other Loan Documents are solely for the
benefit of Lender and the Borrower and nothing contained in this Agreement or
the other Loan Documents shall be deemed to confer upon anyone other than the
Lender and the Borrower any right to insist upon or to enforce the performance
or observance of any of the obligations contained herein or therein.  All
conditions to the obligations of Lender to make the Loan hereunder are imposed
solely and exclusively for the benefit of Lender and no other Person shall have
standing to require satisfaction of such conditions in accordance with their
terms or be entitled to assume that Lender will refuse to make the Loan in the
absence of strict compliance with any or all thereof and no other Person shall
under any circumstances be deemed to be a beneficiary of such conditions, any or
all of which may be freely waived in whole or in part by Lender if, in Lender's
sole discretion, Lender deems it advisable or desirable to do so.

          SECTION 10.15  PUBLICITY.
                         --------- 

          All news releases, publicity or advertising by Borrower or their
Affiliates through any media intended to reach the general public which refers
to the Loan Documents or the financing evidenced by the Loan Documents, to the
Lender, Lehman, or any of their Affiliates shall be subject to the prior written
approval of Lender, which approval shall not be unreasonably withheld.

          SECTION 10.16  CROSS-DEFAULT; CROSS-COLLATERALIZATION;
                         WAIVER OF MARSHALLING OF ASSETS.
                         --------------------------------------

          (a) The Borrower acknowledges that Lender has made the Loan to the
Borrower upon the security of its collective interest in the Properties and in
reliance upon the aggregate of the Properties taken together being of greater
value as collateral security than the sum of the Properties taken separately.
The Borrower agrees that the Mortgages are and will be cross-collateralized and
cross-defaulted with each other so that (i) an Event of Default under any of the
Mortgages shall constitute an Event of Default under each of the other Mortgages
which secure the Note; (ii) an Event of Default under the Note or this Loan
Agreement shall constitute an Event of Default under each Mortgage; and (iii)
each Mortgage shall constitute 

                                      -93-
<PAGE>
 
security for the Note as if a single blanket lien were placed on all of the
Properties as security for the Note.

          (b) To the fullest extent permitted by law, Borrower, for itself and
its successors and assigns, waives all rights to a marshalling of the assets of
Borrower, Borrower's partners and others with interests in Borrower, and of the
Properties, or to a sale in inverse order of alienation in the event of
foreclosure of all or any of the Mortgages, and agrees not to assert any right
under any laws pertaining to the marshalling of assets, the sale in inverse
order of alienation, homestead exemption, the administration of estates of
decedents, or any other matters whatsoever to defeat, reduce or affect the right
of Lender under the Loan Documents to a sale of the Properties for the
collection of the Debt without any prior or different resort for collection or
of the right of Lender to the payment of the Debt out of the net proceeds of the
Properties in preference to every other claimant whatsoever.  In addition,
Borrower, for itself and its successors and assigns, waives in the event of
foreclosure of any or all of the Mortgages, any equitable right otherwise
available to the Borrower which would require the separate sale of the
Properties or require Lender to exhaust its remedies against any Individual
Property or any combination of the Properties before proceeding against any
other Individual Property or combination of Properties; and further in the event
of such foreclosure the Borrower does hereby expressly consents to and
authorizes, at the option of the Lender, the foreclosure and sale either
separately or together of any combination of the Properties.

          SECTION 10.17  WAIVER OF COUNTERCLAIM.
                         ---------------------- 

          Borrower hereby waives the right to assert a counterclaim, other than
a compulsory counterclaim, in any action or proceeding brought against it by
Lender or its agents.

          SECTION 10.18  CONFLICT; CONSTRUCTION OF DOCUMENTS; RELIANCE.
                         --------------------------------------------- 

          In the event of any conflict between the provisions of this Loan
Agreement and any of the other Loan Documents, the provisions of this Loan
Agreement shall control.  The parties hereto acknowledge that they were
represented by competent counsel in connection with the negotiation, drafting
and execution of the Loan Documents and that such Loan Documents shall not be
subject to the principle of construing their meaning against the party which
drafted same.  Borrower acknowledges that, with respect to the Loan, Borrower
shall rely solely on its own judgment and advisors in entering into the Loan
without relying in any manner on any statements, representations or
recommendations of Lender or any parent, subsidiary or affiliate of Lender.
Lender shall not be subject to any limitation whatsoever in the exercise of any
rights or remedies available to it under any of the Loan Documents or any other
agreements or instruments which govern the Loan by virtue of the ownership by it
or any parent, subsidiary or affiliate of Lender of any equity interest any of
them may acquire in Borrower, and Borrower hereby irrevocably waives the right
to raise any defense or take any action on the basis of the foregoing with
respect to Lender's exercise of any such rights or remedies.  Borrower
acknowledges that Lender engages in the business of real estate financings and
other real estate transactions and investments which may be viewed as adverse to
or competitive with the business of the Borrower or its affiliates.

          SECTION 10.19  BROKERS AND FINANCIAL ADVISORS.
                         ------------------------------ 

          Borrower hereby represents that it has dealt with no financial
advisors, brokers, underwriters, placement agents, agents or finders in
connection with the transactions contemplated by this Agreement.  Borrower and
Lender hereby agree to indemnify and hold the other harmless from and against
any and all claims, liabilities, costs and expenses of any kind in any way
relating to or arising from a claim by any Person that such Person acted on
behalf of the indemnifying party in connection with the transactions
contemplated herein.  The provisions of this Section 10.19 shall survive the
                                             -------------                  
expiration and termination of this Agreement and the payment of the Debt.

          SECTION 10.20  PRIOR AGREEMENTS.
                         ---------------- 

          This Agreement and the other Loan Documents contain the entire
agreement of the parties hereto and thereto in respect of the transactions
contemplated hereby and thereby, and all prior agreements among or between such
parties, whether oral or written are superseded by the terms of this Agreement
and the other Loan Documents.

          SECTION 10.21  COUNTERPARTS.
                         ------------ 

          This Agreement may be executed in any number of counterparts, each of
which counterparts shall be deemed an original instrument and all of which
together shall constitute a single Security Instrument.
